Description

  The present invention relates to latching devices for closure devices such as automotive doors and rear door locks, and is particularly useful in electrical central locking systems for vehicles, although not necessarily excluding others. The invention disclosed in this application discloses elements of a latch device, a system incorporating such an element, and a method of manufacturing the latch device. Generally speaking, an object of each invention is to simplify and make such a latching device more compact, thereby reducing its cost and vehicle weight.

  Electronically controlled central locking systems are well known, representative examples of such systems are disclosed in GB-A-2167482, etc., and improved versions are disclosed in PCT publication WO 97/28338, which is the assignee of the present application. Yes. These systems provide centralized control of locking and unlocking of vehicle doors and other closures such as rear doors, bonnets, gasoline caps, and other functions such as lights. This system is designed to mechanically cooperate with a normal type lock mechanism, which includes an external key mechanism and an internal door lock knob on each door. It is normal. With this locking mechanism, the inner and outer door handles are inactivated or neutral.

  The latch mechanism for vehicle doors is WO97 / 19242 entitled “Latch and Latch Actuator Arrangements”, WO97 / 19243 entitled “Latch Actuator Arrangement”, and WO97 / 19 entitled “Latch Actuator Arrangement”. 28337 etc. An electric motor incorporated in the latch and usually controlled by a central locking device is adapted to drive the mechanism for locking and unlocking the latch. Door latches manufactured by other patent publications, such as EP-A-397966 (filed by Roltra-Morese Spa) or GB-A-2221719 (filed by Kiekert GmbH & C0 Kommanditgesellschaft) The problems were size, weight and complexity.

  In addition, a mechanism using an electric motor to complete the closing of a partially closed door is known from US-A-5423582 (Kiekert GmbH & C0 Kommanditgesellschaft application), etc. EP-A-625625 (filed by General Mortors Corporation), etc. which discloses power-assisted door opening and closing are also known. None of these were integrated with the electric central lock. Some of the inventions disclosed in this application provide an integrated electric central lock and electric door opening and / or closing, and even the possibility of using a common electric motor for all of these functions. To do. This presents a substantial improvement over existing technology.

  EP-A-743413 (Application for Rockwell Light Vehicle System (UK) Limited) entitled “Vehicle Door Latch Assembly” to clarify potential savings in the number of latch elements that need to be assembled during manufacturing And so on. That is, a very large number of elements are required here in the vehicle door latch. The present invention can greatly reduce the number of elements by simplifying the mechanical operation of the latch and the cooperation of the latch with the electric motor drive.

  It is important in terms of safety measures to enable a drive system for electric operation such as locking or opening or closing of a door to be overridden by a manual mechanical drive device in the event of an electric failure or failure. Each individual invention can be used in a latch with full mechanical override.

  In order to provide a door opening and closing drive clutch that drives the latch by driving the door handle even in the event of a failure or jamming of the electric drive mechanism, the present invention provides the following section C.1, referred to as claim C.1.1 below. A latch device according to claim 1 is provided.

  Double locks or so-called deadlock or “superlock” mechanisms for vehicles are known per se. When the door is locked by a key mechanism or an electric central lock, it cannot be unlocked by the internal door knob. It can only be unlocked by the internal doorknob if it has been previously locked by the doorknob. In order to accomplish this effectively and simply, the invention provides an automatic door notch with a deadlock type device as defined in claim C.2.1.

  Child safety locks for automobile rear doors are widely known as well. Child safety locks typically have a small lever inside the latch that is opened when the door is opened or only by a special tool to release the internal door handle from the door latch. The present invention makes it possible to carry out such a mechanism at a distance from the latch by means of a driver control panel in the front of the vehicle or a remote-controlled hand-held transmitter, and therefore provides a latch device according to claim C.3.1. Is.

  In order to minimize the cost and weight of the vehicle, the present invention achieves a reduction in the number of key mechanisms. For this reason, a plurality of latches are connected to one key mechanism according to the invention of claim C.4.1. ing.

  Existing vehicle door latches generally include elements within the housing and elements projecting outside the housing, which increases the size of the device. As shown in Kiekert, U.S. Pat. No. 5,419,597, etc., the lever that releases the latch and opens the door and is connected to the door handle by a cable generally protrudes from the latch housing. According to the inventors' knowledge, latch pawls (sometimes referred to as “locking members” as a generic term), pawl release levers connected to the door handle, and preferably pawl release levers are selective to the pawls By providing a common center of rotation for the rotary connecting member for connecting to the door, it is possible to simplify the latch device and accommodate the door handle operating lever in the latch housing. The invention in this respect is claimed in claim C.5.1.

  Door latches typically include a housing to which the elements are permanently riveted so that the door latch cannot be disassembled non-destructively. According to the present invention, in order to solve this problem and simplify the assembly method, the holding means for holding the parallel plate is provided in the housing of the latch assembly, which is described in claim C.6.1. That's right.

In a door latch device incorporating an electric actuating member for locking and unlocking, when one of the door handles is pulled, the locking and unlocking is temporarily blocked and the handle is released. There are those that are designed to release such prevention. Therefore, this device requires repeated operation for locking or unlocking. In order to solve this problem, the present invention allows the operation to be continued until it is completed once the handle is released, and it is not necessary to repeat the operation. In order to achieve this, the present invention is provided with a latch device as described in claim C.7.1.
An automobile key typically generates a rotational output drive by a spindle on the center of rotation or a radial arm connected to the spindle. In order to make the latch assembly more compact and simple, the inventors have found that it is desirable to convert such a rotation mechanism to linear motion within the latch housing for locking or unlocking. Therefore, the present invention constitutes a latch device as defined in claim C.8.1.

  In a drive actuator for coupling an electric motor drive to various actuating members in a latch assembly for door opening and / or closing and / or locking and unlocking or other functions such as child safety restraints It has been found that a rotary type positioning device provided with an elastic connector between the molded part and the molded part on the rotational positioning mechanism is particularly effective. When the positioning mechanism completes its operation over a certain rotational phase, the elasticity of the coupler allows the positioning device to allow continuous rotation past the actuator and prevents jamming. This also simplifies the mechanical structure by allowing positional tolerances. Accordingly, the present invention provides a latch assembly as set forth in claim C.9.1.

  As described above, some of the inventions disclosed herein relate to the opening of a motorized door, i.e., the release of an electrically driven latch mechanism that opens the door. The invention described in claim C.10.1 provides selective connection to a door opening mechanism of a latching device, such as inside or outside a door handle, under the control of a common electric motor. The present invention is particularly advantageous because it provides motorized control independently for each door handle, avoiding the need for the use of mechanical controls for child safety locks. Inevitably, the present invention provides a latch mechanism according to claim C.10.1.

  Some existing latching mechanisms are provided with a so-called emergency door opening device, which allows the door to be unlocked by operating the internal door handle without having to lift the internal door knob. At that time, the door remains unlocked, ensuring that the door can be opened by the internal door handle. This prevents them from being trapped in the vehicle without knowing what they are sitting on. Normally, the door latch is unlocked when the vehicle is moving, but there may be situations where the door latch should be locked when the vehicle is stationary or even moving. The invention of claim C.11.1 provides a compact and simple latch device with an emergency door opening device.

  A particularly important invention is the combination of an electric lock using a common electric motor and an electric door latch release (door opening), which is provided by the invention of claim C.12.1. The invention of claim C.13.1 also provides an electrically driven door closing device using the same electric motor. Preferably, such a latching device also provides selective electrical control of, for example, an internal or external door handle for opening the door, and preferably also provides an electrically operated child safety device.

  The latch device typically includes a latch bolt for engaging a fixed striker in the door frame, and a latch claw for releasably holding the latch bolt to moor the latch bolt. Electric door opening can be achieved by driving the latch pawl. According to the inventors' knowledge, a motorized door latch release and door opening device using a linear actuator acting directly on the latch pawl is particularly advantageous, which device is independent by external mechanical means such as a door handle. The door can be opened. This invention is set forth in claim C.16.1.

  An advantageous alternative to an electrically operated door opening device on the manually operated door opening device, which uses a rotary actuator acting directly on the latch pawl, is described in claim C.17.1.

  An electrically driven door closing device requires a driving force to be applied to the latch bolt, which then pulls the stationary striker and pulls the door to its fully closed position. According to the inventors' knowledge, a particularly advantageous device is to have an electric rotary actuator acting on the bolt. This is described in claim C.18.1. Preferably, this device also provides door opening and the same motorized device, preferably the same rotary actuator, is used to release the latch pawl and open the door.

  As an advantageous variant to the device of claim C.18.1 using a rotary actuator, the present invention also provides a linear actuator acting directly on the latch bolt, which is optional but also a door An opening device can be provided. This is described in claim C.19.1.

  For all these devices, it is preferred that any motorized function can be overridden purely mechanically, i.e. the mechanical drive is independent.

  When the door is fastened with respect to the door latch device, the door may be locked against the will. This is particularly dangerous in the case of centrally controlled electric locking devices in which one door lock is linked to all door locks. The anti-locking device when the existing door is closed and closed is generally of an extremely complex construction, and the purpose of claim C.20.1 is the advantage of the compactness and simplicity of the invention of the other claims It is an object of the present invention to provide an anti-lock device for doors with impact closure.

  This object is achieved by appropriately setting the direction of the reciprocating sliding connecting member in the latch device. According to the claims of C.21.1, the anti-lock function at impact closure is achieved differently, so that the actuator does not move in the latch device whenever the latch device is in an unmoored condition and the door is open. To be secured. The latch device has a fixed molded part that cooperates with the coupling actuator only in its unlocked state.

  As described above, cables, typically Bowden cables, are used to link the latch mechanism to the door handle, key mechanism, and the like. The usual means of connecting the cable end to the actuator arm consists of a special molding on the arm for engaging the cylindrical nipple at the cable end. According to the inventors' knowledge, it is necessary to provide a specially shaped actuator arm for holding the cable nipple, and the invention of claim C.22.1 is a simple plane to form a suitable actuator arm. Can be used. The flange at one end of the blank is folded back to form a suitable formation for receiving and holding the nipple while allowing its free rotation.

  In order that the present invention may be better understood, preferred embodiments of the invention will be described by way of example only, but with reference to the accompanying drawings, in which common reference numerals are consistently the same or equivalent Intended to represent parts.

Centrally Locked Motor Vehicle FIGS. 1 and 2 show a conventional device for locking vehicle doors and other closure devices. The latches L1 to L4 are bolted to each of the four passenger doors, the latch L5 is bolted to the rear door (trunk), and the latch L6 is bolted to the gasoline lock cap. The vehicle battery is connected to a central electronic control system 90, which is connected to the latch by electrical wiring (not shown).

  As shown in FIG. 2, each door has an internal and external handle, a key mechanism which is usually a cylinder type key mechanism, and an internal door knob. The door knob has an unlock position where the knob protrudes from the door frame, and the knob is a door frame. It is constrained so as to move linearly between the locking position and a slightly protruding position. The striker in the form of a cylindrical bar is fixed vertically to the door frame. The door latch mechanism L1 is bolted to the door and the latch bolt engages the striker to hold the door in its closed position, as will be described in detail below. The door has an elastically deformable seal (not shown) that is deformed as the door closes against the frame, and the seal opens the door as soon as the striker is released by the latch bolt. . However, even in the absence of such a seal, the latch bolt is normally spring biased towards the open position so that the latch opens the door.

  The function of the latch L1 will be described in more detail with reference to FIG. This figure also shows a central electronic control unit 90 and a battery, to which the central electronic control unit is connected by an electric cable. A striker 10 is also shown, which is partially surrounded by the jaws of the latch bolt 11.

  The latch claw 20 engages with the edge of the latch bolt, and selectively latches the latch bolt at full depth or half depth according to a normal method. The claw is rotated under the control of various connecting members, and the connecting members include external and internal handles, internal door knobs (if installed), and mechanical child safety lock control devices (if installed). Are linked to each. The electric motor 70 is controlled by the central electronic control unit in accordance with the rotational position of the latch bolt 11 detected by the position sensor and the switch in the latch L1, as described with reference to FIGS.

  Position detection provides the information needed to control most electric functions, including information related to door locks, closures and opening, and not necessarily specified in the following description, Information related to what is included in the latch device.

  The electric motor is controlled to operate the pawl to release the latch bolt for opening the electric door. The electric motor is also controlled to selectively connect the external handle and knob to properly operate the pawl. However, in certain arrangements, separate electric motors can be provided for this purpose, depending on design needs and available space.

  A central electronic control unit 90 is shown in FIG. 4 with four doors and rear doors and an electric motor shown at A for the filler (gasoline) cap clasp and for the engine room clasp. In this example, the internal lock is simply actuated by the electric switch R6, avoiding the need for an internal door knob, but such a knob may be provided. The function of this circuit will not be described in detail here, please refer to the above-mentioned WO97 / 28338 for more details.

  The electronic control system will be described below with reference to FIGS. According to the present invention, position detection using a microswitch is provided, and the microswitch reverses the polarity of the power supply to the motor in accordance with the reciprocating motion of the main body driven by the motor, in this case, the latch bolt 11. This mechanically responsive power supply is operated with electronic control by a relay switch to initiate door opening, as will be described below with reference to FIG.

  As shown in FIG. 5, the cam member 101 is arranged to rotate about the same shaft 15 as the latch bolt 11 and is driven by a projection 140 that engages with the recess 141 in the latch bolt 11. As shown in FIG. 5, the latch housing 100 has three parallel layers that are interconnected by a hinge on a shaft 15 for both the cam member 101 and the latch bolt 11. . The cam member 101 can slide up and down on the rotation shaft, and the cam driven micro switch actuators 111, 121 and 131 are caused to follow the rectangular cam tracks C, B and A shown in FIG. The cam member 101 is biased upward by the spiral spring 19 in the upward direction in FIG. 5 and downward in the direction of the arrow 191 in FIG. The microswitches 110, 120, and 130 that overlap the three layers are rigidly connected to the latch housing 100, and the corresponding microphone switch actuators are moved along the respective rectangular cam tracks.

  The surface of the cam member 101 facing the microswitch stack is shown on an enlarged scale in FIG. The unmarked portion of each cam track is the deepest portion indicated by the line 102 in FIG. 4, and the darkly imprinted portion in FIG. 6 is the shallow floor surface for the cam track indicated by the line 103 in FIG. Represents. The ramp from the deep region to the shallow region is represented by an imprint of intermediate darkness in FIG. Each rectangular cam track is delimited by the illustrated rectangular wall and by the central walls 104, 105 and 106. The pin-type microswitch actuators 111, 121 and 131 are represented by circles, and these circles represent the positions of movement along the respective cam tracks. When the door is opened, the microswitch actuator is in the upper right corner of the cam track in FIG. When the door starts to close, its relative position is moved in the direction indicated by the letter L in FIG. 6 toward the positions indicated by A, B, and C. In this position, the door is completely closed.

  A molded portion H extending obliquely across the central cam track B and continuing to the end face of the intermediate wall 105 causes the entire cam assembly 101 to resist spring bias as the latch bolt 11 moves toward the door open position. Push up in direction M. This is due to the sliding cam action of the pin 121 on the step H. Continued movement in direction K returns the microswitch actuator to position F, where the spring force 191 returns the microswitch actuator to the upper right corner shown in FIG. 6 and the cam assembly is moved in direction N. The ramp E pushes the cam actuator into the respective microswitch and switches the microswitch from “off” to “on”. The steep step H causes the microswitch actuator to pop out again under elasticity, turning off the microswitch.

  The motor control will be described below with reference to FIGS. 7 and 8, which are alternative circuit arrangement examples. In a motor vehicle, each door is controlled by its own motor 70, and each door has a red warning light 80, which allows the driver to warn that the door has been opened. . The vehicle includes a central electronic control unit 90, which includes a normal type integrated stop current detection circuit 91. The first micro switch 110 controls the switching of the door warning lamp 80. The second microswitch 120 provides a motor power polarity suitable for door closing control. The third micro switch 130 supplies electric power of the opposite polarity of the motor suitable for door opening control. The mechanical arrangement of FIGS. 5 and 6 can ensure the correct operating sequence of these microswitches. Using normal indications, NO indicates normally an open terminal, NC normally indicates a closed terminal, and C indicates a common terminal. When the door is closed, the microswitch actuator is in positions A, B and C in FIG. 6, and all microswitches are off. Movement to the open position causes the microswitch actuator to move along the arrow K in FIG. 6, and after a slight intermediate movement, the microswitch 130 is turned on and the actuator 131 rides on the ramp E. This opens the power assist door. When the actuator 111 rides on a dedicated ramp while the door is open, the door warning light control switch is turned on. When the door reaches the end of the power assist motion, the door opening switch 130 is turned off and only the door warning light remains on. When the door is reclosed, the door closure control microswitch is switched on as soon as the actuator 121 rides on the ramp from line F in FIG. The warning light is turned off while the door is closed.

  When fully closed, the door closing microswitch 120 is switched off when the actuator 121 falls from the step G in FIG.

  Preferably, the door opening is initiated by a central electronic controller, which is provided by the relay switch 140 of FIG. The signal from the central control circuit 90 turns on the relay 140 along the wiring 150, feeds the motor, and turns on for a period of time sufficient to move the mechanical device to the position where the third microswitch 130 is switched on. Let me stay. The relay switch is then turned off or times out.

The stop current detection circuit 91 will not require detailed description. In this example, this circuit is a circuit breaker that provides overcurrent protection, and can be reset by manual operation when trip current detection of the drive motor current is performed in the ground return circuit, and the current detection is applied at the appropriate voltage. This can be done by a resistor that is amplified by an integrated differential amplifier. The second amplifier determines the voltage difference between the resistance value and the reference voltage value provided by the temperature stable diode. The second differential amplifier operates as a comparator, compares at the logic level, and outputs a stop signal.
A remote control transmitter is normally provided to control the central locking system, such as for locking or unlocking from the outside of the vehicle. The same command signal can be used by the central control system to open a door or a specific door by remote control. However, the same type of remote control can be employed in accordance with the present invention to operate the electric safety lock device.

  The central control circuit is preferably capable of receiving input from sensors, some of which are located inside the latch and determine the position of the pawl, latch bolt and pawl actuator, or any other part of the latch mechanism To do. Some other sensor is preferably located somewhere in the vehicle to monitor vehicle engine status and the like. For example, the current supplied to the drive motor can be cut off by the central control circuit 90 when the engine is started and the vehicle is moving. This is a safeguard against accidental opening of the electric door. In another embodiment, when the door movement is hindered and the motor drive is stopped, the current detection circuit 91 sends a message to the central control circuit 90, which may release the door handle or position the door. The current that feeds the motor is cut off until a predetermined suitable condition such as manual movement is detected.

  In motorized vehicles, the particular configuration described above provides significant cost advantages. By incorporating the switch in the latch housing, the wiring length is minimized and the necessary wiring is linked to only the two wirings in FIG. 7 that link the door latch to the central control unit or the four wirings in FIG. It is possible to reduce to only 150, 151 and 152. Wiring and assembly costs can be minimized by integrating the door warning light into the door latch, such as by a simple plug-in lamp. Consolidating the door opening and closing microswitches in the same stack is the most efficient arrangement and minimizes wiring length.

Electric door opening and / or closing The operation of latch bolts and pawls in relation to door movement will now be described with reference to FIGS. 19-21 and the issued patent specification.

  As shown in FIG. 9, the latch bolt 11 accessible to the periphery of the striker 10 has notches 13 and 14 for mooring the claw 20 in full latch and half latch respectively. The latch bolt 11 is spring-biased clockwise toward the open position, and the pawl 20 is spring-biased counterclockwise (B5) to the anchor position in FIG. 6 where the latch bolt is moored. The electric motor 70 has a rotation output shaft having a crown-bevel gear mechanism with respect to the rotation output drive unit 50, the rotation output drive unit 50 is arranged to rotate in the direction D1, and the protruding pin 30 positioned eccentrically is a claw. 20 is driven in the direction D2 toward the unlocked position. If the rotation in the direction D1 continues, the pin 30 pulls the pawl 20 back by the spring force in the direction D5, and again latches the latch bolt after the door is closed.

  The pin 30 returns to the original neutral position NP as shown in FIG. 9 when driven by the electric motor 70 in the reverse direction, otherwise by the force of the pawl 20 returning to the mooring position. And in this neutral position, it waits for the next door opening operation | movement.

  Obviously, alternative output drive coupling means such as screws or spur gears can be employed. Further, the pin 30 can be replaced with a cam device having an appropriate shape that comes into contact with the claw.

  In this device, the door is opened when the pawl is moved to its unlocked position under the force of an elastically deformed door seal. The fact that the latch bolt 11 is spring biased also contributes to the opening of the door.

  An alternative form of door opening device is shown in FIG. The output drive of the electric motor 70 is in the form of a rack-pinion device 31, which generates a linear drive in the direction D <b> 1, and the rack is in contact with the claw 20. When it is detected that the latch bolt has moved to its fully unlocked position, the electric motor is switched off or driven in the reverse direction, and the rack 31 is returned to the neutral position shown in FIG. When the switch is off, the rack remains in the door open position until the door is closed. Closing the door causes the pawl to rotate to the latched engagement position and simultaneously return the rack to its neutral position. This is assisted by the pawl 20 being spring biased.

  The detection of the position of the latch bolt naturally corresponds to the apparatus shown in FIG. 9, whereby the electric motor is either switched off or driven in the reverse direction.

  The apparatus of FIGS. 9 and 10 is suitable for a side door of a vehicle. The rear door and the trunk are different from those shown in that they usually have a single notch 13 for full latching of the bolt. Similarly, various alternative transmissions are of course possible.

  The latch device shown in FIG. 11 provides power door closing and electric door opening. It is an opening and closing mechanism driven by the same electric motor 70. The electric motor selectively drives the rotational positioning drive member 50 in either direction D1 or D4. A neutral position NP shown in FIG. 11 corresponds to a position where the pin 34 does not contact the door latch 11. The positioning drive member 50 is rotationally biased toward its neutral position by a torsion spring 36 attached coaxially to the member 50, and is restrained by a bar 35 fixed to the latch housing. The torsion spring 36 has two rims 33 </ b> A and 33 </ b> B that engage with opposite sides of the protruding pin 34. Thus, when member 50 is driven clockwise in direction D1, pin 34 drives rim 33A of the spring, which causes member 50 to return in the opposite direction toward the neutral position. Similarly, counterclockwise movement D4 causes pin 34 to displace spring rim 33B, and similarly spring returns member 50.

  In this embodiment, the pawl 20 is locked or unlocked indirectly by the actuating plate 38, which is pivotally attached to the pawl 20 at 40 and has the arcuate slot 39 and the protruding pin 32 of the member 50. To the rotational positioning drive mechanism 50. The arcuate slot 39 of the actuating plate 38 is coaxial with the rotating member 50, and its function is to allow a relative rotation of the rotating member 50 of about 70 ° in the clockwise direction D1 for closing the door without interference.

  The extension 37 of the latch bolt 11 protrudes above the rotational positioning drive member 50 for selective engagement with the pin 34. Due to the closing of the door, the pin 34 is driven in the direction D1 until the position A where the latch bolt 11 will reach as a result of manual partial closing of the door. Completion of the closing of the door is accomplished by a pin 34 that abuts the extension 37 and drives the extension to the fully latched position B in direction D3. When it is electrically detected that the latch bolt 11 is completely latched, the motor is switched off and the rotating member 50 is returned to the neutral position NP by the spring 36.

  In order to open the door electrically, the motor drives the pin 34 and drives it counterclockwise D4, pulls the pin 32 and immediately pulls the end of the slot 39, pulls the claw 20 in the direction D5, Release in direction D6. Then, as the door moves away from the frame in the direction D8, the latch bolt opens in the direction D7 under elasticity. When it is electrically detected that the latch bolt has reached the fully unlocked position, the motor is switched off and the rotating member 50 returns to its neutral position NP under elasticity.

  The motorized position sensor is properly positioned in the latch, so that, for example, when the pawl 20 is actuated to its unlocked position, it is prevented from falling to the half latched position in the notch 14.

  This device can be housed in a single housing, is compact and simple to manufacture, improves soundproofing and reduces manufacturing costs.

  The latch device of FIG. 12 is a modification of FIG. 11, and can open and close the door. In this example, the operating plate 41, which is an alternative to the plate 38, is arranged to slide on the pivot shaft 43 of the rotational positioning drive member 50. The plate has a slot 45 for guiding on the pivot 43. The actuating plate 41 has an end flange 44 </ b> A that hangs downward to engage and engage with the pin 34 of the rotating member 50. The operation plate 41 can slide between positions C and C1 corresponding to the mooring position and the release position of the claw 20, respectively.

  In order to cause the door to close, the pin 34 is rotated clockwise in the direction D3 and is brought into contact with the latch bolt extension 37 at A to drive the latch bolt extension to the position A1. After moving slightly beyond the point A1, the cam pin 34 moves away from the latch bolt and rotates in the direction D3 toward the second neutral position NP1. Accordingly, the first neutral position NP1 is located immediately before the cam pin 34 is engaged with the latch bolt extension 37. The second neutral position NP2 is located immediately after A1 and before the pin engages with the flange 44A. When separated from the latch bolt, the cam pin 34 is stopped at the second neutral position NP2 by elastic deformation means such as a spring (not shown) after the motor is switched off under the control of an appropriate electric position sensor (not shown). . The motor can also be stopped in the second neutral position by a controlled drive of the motor in the reverse direction.

  In order to open the door electrically, the motor is energized and drives the cam pin from its neutral position 34B to the position 34C in the direction D3, where the cam pin contacts the actuator plate 41 at point C1, at which point the flange Reaches position 44B in direction D7. This is done by clawing to rotate in direction D4 to the fully released position, and latch bolt to rotate in direction D5, and at the same time move away from the striker in direction D6. The cam pin 34 continues to move in the same direction until it reaches the first neutral point NP1.

  In any neutral position, the latch bolts and pawls can be freely operated manually in the usual way between the mooring position and the release position. This normal mechanical operation is prevented only during the opening and closing of the motorized door. This provides a complete mechanical override as a safety measure against the malfunction of the electric mechanism.

  Unlike the device of FIG. 11, the rotary positioning drive member 50 is rotated in a single direction, but its movement is either braked or partially reversed by a reverse electric drive.

  The configuration of FIG. 12 is more compact than the configuration of FIG. 11 and has the advantage of soundproofing.

  The modification of FIG. 13 shows an electric door opening and closing device using the same electric motor 70. In this example, the rotary drive output at 50 is converted into linear motion by a rack-pinion. The rack 56 is formed integrally with a reciprocating body having an end contact surface 55 for engaging with the latch bolt extension 37. At the other end, the rack is connected to a coil spring 58 at 57 and the coil spring is mounted on a latch housing frame 59 for compression and tension. The spring serves to return the reciprocating body to the neutral position NP, absorb the shock, and reduce noise.

  The reciprocating body 56 is drivingly connected to the actuator plate 52 by a pin 54 moving in the slot 53 so that the reciprocating body can be driven to close the door without interfering with the latch bolt. The actuator plate 52 is pivotally attached to the claw 20 at 51 sites.

  Similar to the arrangement of FIGS. 11 and 12, the electric drive mechanism is isolated from the normal mechanical latching action, whereby the door handle operates the pawl in its neutral position NP.

  Thus, to open the door, the reciprocating body 56 is driven from its neutral position to the extreme position P1 in the direction D3, after which the electric motor is switched off and returns to the neutral position. The electric door opening is achieved by driving the reciprocating body in the direction D5 from the neutral position toward the second extreme position P2, pulling the operating lever 52 and releasing the pawl.

  Since this configuration has a larger gear ratio, a smaller drive motor can be used.

  Another embodiment of the door opening and closing mechanism is shown in FIG. Instead of the rack-pinion device, the linear reciprocating body 71 is driven by the cam pin 34 of the rotational positioning drive member 50 in either the linear direction D1 or D2. The cam pin 34 rides on a cam 74 fixed to the reciprocating body 71 and is driven at a limited angle or phase range such as about 40 ° of the rotating member 50. Similarly, the reciprocating body 71 is biased toward the neutral position by a compression spring 72 attached to the frame 73. The reciprocating body has an end molding portion 78 that is drivingly abutting the latch bolt extension 37 and moves the latch bolt extension from position A to position B. An actuator plate 77 corresponding to the plate 52 is provided to link the reciprocating body 71 to the claw 20 for closing the electric door. Similar to the configuration of FIG. 13, the pin 75 on the reciprocating body slides in the groove 76 of the actuator plate 77.

  The configuration of FIG. 14 has the added advantage of flexibility and provides ease of movement to the neutral position of the drive mechanism when motorized operation is permanently inhibited.

  An alternative device for opening the electrical door is shown in FIG. In this example, the reciprocating body 83 similarly constrained to move linearly is driven from the electric motor 70 by a lead screw in the form of a screw 81 and an internal screw nut 82. The lead screw 81 is driven by the bevel gear device 80 from the rotation output drive unit. Similarly, the reciprocating body is biased to the neutral position by a tension-compression spring 86. The slot 84 connected to the pin 85 of the claw 20 provides sufficient freedom to allow independent mechanical opening as before. In this example, no door closing is provided, but it is possible to incorporate the door closing device of FIGS. 12 and 13 into this device. This device is simplified and provides the reciprocating body 83 with only one neutral position A and one working position B.

  This arrangement has the further advantage that the mechanical door opening and closing is completely independent of the electric device at all stages of the electric door opening. It also has the advantage that a relatively small motor can be used due to the high gear ratio and that it is extremely compatible and simple. As before, the compression-tension spring provides a backlash prevention device that reduces noise by absorbing the inertia of the machine after the motor is switched off, which also extends the life of the drive mechanism.

  Another variation of the opening and closing mechanism is shown in FIG. In this example, the reciprocating body 95 is linearly driven by a lead screw 96 between two spaced tension springs 97 and 98, which are mounted between the fixed brackets 99 and 200 on the lead screw 96. The lead screw is driven by a bevel gear that is powered by a motor 70. Similarly, the actuator plate 91 is connected to the reciprocating body 95 by a pin 92 that slides in the slot 94, and the reciprocating body 95 has a contact surface at an end 93A, and this contact surface is a neutral position 93B that is a position A. And a lower position 93C, which is a position C where the pawl is released, and an upper extreme position 93A, which is a position B where the latch bolt is completely closed.

  Preferably, the nut 95 and the screw 96 formed integrally with the reciprocating body have meshing teeth cut at 45 ° with respect to the rotational axis of the lead screw 96, so that the reciprocating body can drive the lead screw and vice versa. Is true. This means of constraining the nut 95 for linear motion can take any suitable form, such as a rail (not shown) fixed or integral with the groove and latch housing (not shown).

  The springs 97, 98 can be replaced by a single spring that can be used as a compression or tension spring connected to the nut 95. This can also be a torsion spring connected to the drive mechanism.

  In the above configuration, electric position detection is adopted for controlling the power supply to the electric motor. A control circuit can be incorporated into the current sensor, which provides an indicator that the latch bolt has reached its latched position. That is, only the movement beyond that position increases the current. Similarly, the inertia of the moving part can be canceled by temporarily reversing the polarity of the electric drive.

  This arrangement has advantages corresponding to those of the apparatus of FIGS.

  With respect to any of the devices shown in FIGS. 9 to 16, a clutch mechanism can be provided at the rotation output portion of the electric motor 70. A normal centrifugal clutch is preferred. This eliminates the induced current generated in the motor when it is driven by mechanical parts. This also assists in reducing the load on the return spring used to provide a mechanical return to the neutral position after the electric drive.

  FIG. 17 shows another modification of the electric door opening and closing latch device described above. In this example, the actuator plate 202 is pivotally attached to the claw 20 near the engagement point with the latch bolt 11 at a portion 203. Therefore, since there is no lever action, the actuator plate can be operated in the reverse direction. The actuator plate 202 is rotated around the rotation shaft of the rotary positioning drive mechanism 50 by an end fork provided with rims 205 and 206 provided on both sides of the swing shaft, or moves linearly in the operation direction D4. Be bound.

  In this example, the cam pins 34 are replaced by a plurality of radial cams, all of which are integral with the rotating mechanism 50 and arranged in two separate planes perpendicular to the pivot axis. In the first plane, the radial cam 207 selectively contacts and drives the latch bolt extension 37. In another plane, the radial cams 209 and 208 spaced about 100 ° engage respectively with the hanging lug 204 of the door opening actuating plate 202 and the W-shaped leaf spring 210 fixed to the latch housing. The W-shaped plate spring 210 is a shock absorber when the cam 208 rides on any rim and makes the cam center. Spring 210 prevents backlash and positions the device in the neutral position as shown.

  To close the door, as before, the rotating member 50 is driven clockwise in the direction D1 to drive the cam 207 relative to the latch bolt extension 37. To open the door electrically, the rotating member 50 is driven in the direction D1 from the neutral position, engages the lug 204, drives the drive plate 202 in the direction D4, and releases the pawl.

  When the electric drive is interrupted for some reason, the drive device returns to the neutral position by a spring (not shown) connected to the drive device. This realizes mechanical override at the time of electric failure.

  The latch device of FIG. 18 (A) uses one electric motor 70 and one rotation positioning drive device 50, and the independent control of the door opening and closing mechanism on the one hand, and the electric lock on the other hand. Yes. The door opening and closing mechanism includes a reciprocating body 215 constrained to move linearly and connected to a tension-compression spring 218, as described in connection with FIG. The rotating member 50 comprises a single cam pin 34, which can be rotated in either direction D1, D5 between two neutral positions NP1 and NP2, in which the cam pin has a W-shaped fixed spring 220 and 219 are restrained respectively. The actuating member 222 is constrained to move linearly in either direction D11, D12 between positions C1 and C2, and the actuating member has a toggle lever 221 at the end for engagement with the cam pin 34. The toggle lever 221 can be of the type described and described later in connection with FIG. The toggle lever is pivotally attached to the end of the actuating member 222 and biased toward a neutral position perpendicular to the length direction of the actuating member 222 by a torsion spring 223. This arrangement causes the cam pin 34 to drively contact the toggle 221 and drive the actuating member in the direction D11, but releases the actuating member when the toggle is elastically deformed against the torsion of the spring, and the cam pin 34 To continue the rotational movement. In this example, the toggle can be driven in either direction by a cam pin 34.

  Similar to the W-shaped spring 210 of FIG. 17, the springs 219 and 220 have a function of absorbing rotational impact when the pin rides on the extension rim of the spring from either direction. The cam pin is then moved to settle in the central recess between the two outer rims of the pin. This prevents overriding from occurring unintentionally.

  The locking and unlocking of the electric door using the actuating member 222 will be described in more detail later with reference to FIGS. 24, 26, 30 to 38. Briefly, the actuating member interacts with the key mechanism to selectively unlock or lock the pawl 20 to prevent or allow the door handle or the like to be transmitted to the pawl.

  A variation of the door opening mechanism of FIG. 10 that provides electric locking and unlocking under the control of the same electric motor 70 is shown in FIG. In this example, the rack-pinion device integrated with the linear reciprocating body drives the pawl 20 on the contact surface 231. The pawl 20 includes an extension bar 232 that is driven by a cable or other link to the contact surface 231 or even a latch lock mechanism (not shown). Similarly, the tension-compression spring 235 biases the reciprocating body toward the neutral position N.

  For motorized locking, the notch 234 in the reciprocating body is engaged with the end 1814 of a lever pivoted on 1810 at the center 1812 which is directed to the neutral position shown by a torsion spring 1813 on the pivot shaft 1812. Spring biased. The opposing rim 1811 engages in a notch in the actuating member 300 that can move in either direction D7 to lock and unlock the latch.

  FIG. 18 (C) shows another device for opening and closing the door, which is similar to the device described below with respect to FIG. The rotating member 50 acts directly on the claw 20 having the extension arm 20A and the latch bolt extension 37. The cam pin 30 is biased toward the neutral position N by a spring 1804 positioned around the fixed lock 1801.

  The door is closed by driving the cam pin for the extension 37 in position A towards position B. It is then forced back to the neutral position by a spring. When the motor is driven in the reverse direction, the cam pin 30 moves in the direction D2, contacts the claw 20A, and releases the latch bolt. Again, the cam pin 30 is returned to the neutral position by an electric or return spring.

  As an alternative, the claw 20 can be manually released by a lever 246 and a cable 245 by an externally operable means such as a handle.

  In this example, the end portion 20A of the claw 20 is lifted by the bent portion so that the latch bolt extension portion 37 can be overridden.

  This particular arrangement allows for a reduction in drive torque and makes the device more adaptable.

Door Opening and / or Closing under Electric Power The configuration shown in Figures 19-21 provides an electric door opening which causes the pawls to be first released and then the latch bolts to be driven electrically And is designed to ensure full opening. This arrangement provides a power driven door closure similar to the previous arrangement.

  Referring to FIGS. 19-21 in the drawings, a vehicle door closing device includes a striker 10 connected to a vehicle door frame, and a latch bolt 11 forming a part of a latch device supported on an edge of the vehicle door. It comprises. The form of the latch bolt 11 of FIG. 19 is unique to the present invention, but its general function is normal and it is not necessary to describe it in detail here. The latch bolt 11 is pivotally attached at 15 sites, and is driven by the relative movement of the striker 10 in a U-shaped notch 12 formed in the latch bolt 11 and rotates as indicated by an arrow 18. The latch bolt 11 has two separate notches 13 and 14 for engagement with the lock pawl 20 on its outer periphery. The notch 13 is for locking the latch bolt in a certain rotational position. In this position, the striker 10 is restrained and the vehicle door is kept closed. The door can be opened to the right in FIG. 1, so that the pawl 20 is released from the locked position in the notch 13 and the striker 10 is driven under the cam action of the recess 12 to drive the latch bolt 11 clockwise 18. And the striker 10 is no longer restrained. However, if the locking claw 20 is engaged with another notch 14 in a so-called half-latch position, the door is in a partially open semi-constrained state.

  The lock pawl 20 is pivotally attached at 21 and the pivot points 15 and 21 are both fixed to a latch housing (not shown). The pawl 20 includes end teeth 24 for locking engagement at the notches 13 and 14. At the same end, the claw is provided with a pin 23, on which a link arm 25 is pivotally connected, and the link arm is connected to a door handle for driving the claw. By lifting the door handle, the link arm 25 moves in the direction of the arrow 26, pulls the claw 20 counterclockwise as shown by the arrow 22, and moves the claw to its unlocked position (not shown).

  According to the invention, the latch bolt 11 is drivingly connected to an electric motor 70 of the type normally used for central locking of the vehicle door. This connection structure, described in detail below, also incorporates a device for releasing the pawl.

  The motor 70 is connected to the latch bolt 11 via gears 40, 50, 60. The gear 40 shown separately in FIG. 20 meshes with the teeth 16 on the latch bolt 11 at 45 sites. This gear is mounted for rotation about a shaft 42, which is in common with the large diameter gear 50 shown separately in FIG. The gear 50 is drivingly connected to the gear 40 with a play of rotation of 60 °. Therefore, a pair of slots 52 and 53 are provided on one side surface of the gear 50, and a pair of driving pins 44 connected to the gear 40 through the slots. , 43 protrudes. This 60 ° free play is important in this embodiment because it allows for proper sequence of claw release and latch bolt drive.

  The rotational movement of the gear 50 in the direction indicated by the arrow 41 is controlled by direct engagement with the spindle of the motor 70. In the embodiment of FIG. 19, this connection is made by meshing the gear 71 on the motor spindle 62 with the teeth 62 of the crown gear 60, and the gear 60 is connected to a small-diameter gear 61 that drives the teeth 54 of the gear 60. It is like that. In an alternative embodiment shown in FIG. 21, the worm gear 72 is driven directly by the motor spindle and drives the gear 50 directly.

  The gear 50 has a U-shaped recess 51, and this recess cams the rim 33 protruding from the hook 32 at the end of the claw actuator 30. The actuator 30 is constrained by a molding portion on a latch housing (not shown), and reciprocates in the direction of the arrow 34 in FIG. 19 so as to be mechanically linked to the pin 23 of the claw 20. . The upper end of the claw actuator 30 is formed in a dog leg shape having an extension part in which a slot surrounding the pin 23 is formed. This arrangement provides free play in the drive connection between the pawl actuator 30 and the pawl 20.

  The operation of the power assisted door latch will be described below. It should be noted that the door latch can be mechanically driven without motor power or operated under motor drive. This is an important safety point.

  First, the operation under power will be described. As shown in FIG. 19, when the door is closed, the latch bolt 11 is in its mooring position, and the lock claw 20 is in the lock position. The pawl actuator 30 is in engagement with the gear 50. When the door opening command is received from the central control circuit 90, the motor 70 drives the gear 50 counterclockwise as indicated by 41. At the first 60 ° rotation, the gear 40 remains stationary and does not attempt to rotate the latch 11. Otherwise, the latch and pawl will jam. The notch 51 pushes the claw actuator 30 in the direction of the arrow 34, and the claw actuator immediately pushes the pin 23, drives the claw counterclockwise as shown by the arrow 22, and moves the claw toward the unlock position. When the rotation of the gear 50 continues, the extension portion 33 of the claw actuator 30 is lifted, and the extension portion rides on the peripheral surface of the gear 50 and temporarily prevents re-invasion. To continue the rotation beyond 60 °, the walls of the slots 52 and 53 are engaged with the pins 44 and 43 of the small-diameter gear 40, and the latch bolt 11 is driven in the direction of the arrow 18. Such a power-type operation can intentionally avoid the half-latch state. Thus, the latch bolt is rotated and the notch 14 passes through the tooth 24 and the outer surface of the bolt 11 is engaged with the tooth 24 of the claw 20, thereby avoiding re-entry of the claw.

  In the electronic position sensor described below, the motor drive unit is switched off with the vehicle door partially opened to pass through the unconstrained position. It can then be conveniently opened completely by the passenger or driver.

  The clockwise driving of the latch bolt has a favorable effect of pushing the door opened by the reaction against the striker 10. This facilitates the opening movement of the door, and such opening movement continues until it is decelerated by the amount of friction of the door hinge in accordance with the tilt of the vehicle.

  When the door is closed, the door reaches the same position, just beyond the half-latch position, and switches on the electric motor again with reverse polarity (described below). The motor then provides a power assisted door closure to ensure that the door is properly closed and locked. Similarly, a half-latch position is not possible with a power-assisted closing operation. When the door begins to fully close, the counterclockwise rotation of the latch bolt is accompanied by the clockwise rotation of the small diameter gear 40 along with the large diameter gear 50. After such a first phase of rotation, the extension 33 of the pawl actuator 30 translates downward and downward. Free play between the pawl actuator and the pawl 20 allows the pawl 20 to ride on the slot 14 and then enter the slot 13 without jamming under a spring bias in the clockwise direction. When the teeth 24 are immersed in the slot 13, the device returns to the state of FIG.

  Without power assistance, the latch can be controlled by the door handle through the link arm 25. The mechanical interaction remains the same and the opening and closing of the door causes the motor spindle to rotate, but this provides only a small amount of mechanical resistance. When the link arm 25 is lifted, the claws are removed, the door is allowed to open, and the latch bolt 11 is rotated clockwise by the striker 10. Again, the pawl actuator 30 is disengaged from the gear 50 and the door is released. It should be noted that the mechanical operation sequence is the same, so that power-assisted closure follows non-power-assisted opening and vice versa. When the latch is actuated purely mechanically, the teeth 24 of the pawl 20 can be located in a half-latch position within the notch 14. This is an additional advantage of the safety mechanism.

  A variation of the arrangement of FIGS. 10 and 18 (B) providing door opening and closing is shown in FIG. Needless to say, the contact surface 231 of the reciprocating body 233 claws and drives on the extension arm 232 to move the extension arm to its position 232A. Continued movement in the same direction drives the latch bolt extension 37 to its release position 37A. Similar to the configuration of FIG. 18 (B), the notch 234 engages with a link lever (1810 in FIG. 18 (B)) for electric locking and unlocking.

  A motorized opening mechanism particularly suitable for trunks and rear doors is shown in FIG. The rotation output drive unit 50 of the motor 70 is rigidly connected to the lead screw 240, and this lead screw is screwed into the inner screw in the nut portion 243 and has an internal hole for accommodating the lead screw 240. The end contact surface of the reciprocating body 242 engages and drives the claw 20. As in the other configurations, the claw portion 244 is connected to an external manual control unit such as a handle via a lever 246 by a link 245, and the latch is released by a key mechanism, an internal door knob, or an electric control mechanism (not shown). Then, the door can be opened. The nut 243 and the reciprocating body are illustrated by at least one of the following mechanisms after each drive: a return spring acting on the nut, a return nut acting on the pawl, and a motor refeed that moves the nut in direction D6. Return to the neutral position. The nut 243 is restrained from moving in a linear direction by suitable means such as a rail fixed to the housing.

  According to an alternative embodiment, the lead screw 240 meshes with the internal thread 241 in the rotary drive gear 50, and the lead screw is formed integrally with the reciprocating body 242. Other mechanically equivalent operations will be apparent to the skilled reader.

  A compact latching device is shown in FIG. The housing 250 has a rounded corner and a flat rectangular box with a U-shaped opening that houses the striker 10. The housing includes an end plate 252 and a side wall 251 facing each other, and an internal compartment 253 for accommodating the electric motor 70 and the rotation output gear 50 is formed. Cables 256, 258 for driving the respective levers 255 and 257 protrude through the side walls and are connected to the levers by nipples held in the end moldings. A preferred specific connection structure will be described later with reference to FIG.

  Of particular importance for the compactness of this arrangement is that several elements are mounted on the same pivot shaft 21 including the pawl 20. This latch device provides motorized locking and unlocking.

  The claw 20 includes a lever arm formed with a fork 259, and the lever arm is driven to rotate. The claw release lever 255 is pivotally attached to the claw shaft 21 and can be driven by an external manual control unit such as an internal or external door handle. The rotational movement of the claw release lever 255 is transmitted to the claw fork only by the rotary coupling members 300, 400 carrying the hanging lugs 262 arranged parallel to the pivot axis. The clockwise rotation of the claw release lever 255 causes its end notch 263 to engage the lug 262, and then the lug is driven relative to the fork 259. This guides the pawl 20 to the release position and allows the door to open.

  The rotary coupling members 300 and 400 are pivotally mounted around the pivot shaft 21, but can be slid perpendicularly to the pivot shaft by an egg-shaped slot formed in both members 300 and 400. . The locking member 300 is a straight line between the leftmost position shown in FIG. 24 where the door is unlocked and the rightmost position where the claw release lever 255 is no longer connected to the claw 20, in other words, neutral. Restrained to move. The rotary sliding member 400 includes an arcuate slot that extends over the pin 301 of the locking member 300 and integrally forms a hanging lug 262. The slot acts as a rotary sliding member and allows rotational sliding movement integral with the claw release lever 255 when these are connected by the lug 262. When the locking member 300 is moved to the right to the locking position that neutralizes the claw release lever, the lug 262 is moved with it and is no longer engaged with the notch 263 of the claw release lever.

  The rotary coupling members 300 and 400 are selectively driven by the output disk 500 together with the eccentric pin driven by the bevel gear 50 of the motor 70. The pin drives the locking member 300 through a notch or other shaped part. Such a coupling device will be described in more detail with reference to FIGS. 25, 26, 35-38 in various alternative embodiments.

  Mechanical locking and unlocking is achieved by lever 257 from a key mechanism or internal knob, for example. This drives the lock member 300 and biases the electric motor when it is not powered. Thus, the latch device provides independent mechanical and motorized locking and unlocking.

  A member 254, only part of which is shown, is also drivingly connected to a portion of the locking member 300 for locking and unlocking.

  As long as the rotary sliding member 400 with a lug 262 permanently connected to the fork 259 of the pawl 20 is rotationally driven, it will move out of the housing to move between the locked and unlocked positions. Boss or elongated block 260 is blocked. When the fork 259 rides on the boss 260, the lug 262 cannot move in the radial direction of the pivot shaft 21 past the boss 260 in any radial direction.

Anti-Lock on Shock Closure Boss 260 also has a preferred function to provide anti-lock on impact closure of the latch. The boss 260 prevents the door from being unintentionally locked and keeps the door handle open and the pawl is in its unengaged position, which is due to the radial engagement of the lug 262 with the boss 260 and the locking member 300. This can be achieved by preventing the sliding. Therefore, even if the door latch is not locked and the door is closed, the rotary coupling members 300 and 400 are held in the housing, preventing the door from being unintentionally locked.

  Even without such a locking device having a boss 260, the latch device can be configured to have an anti-locking function during impact closure. In the configuration shown in FIG. 24 and also shown in FIGS. 25 and 26, the locking position of the locking member 300 is the right side away from the striker 10. The direction of the latch bolt is such that the door is closed in the left direction. Thus, if the latch is unlocked prior to closing the door, the locking member 300 will be completely on the right and any impact when closing the door will not affect its position. However, if the door is locked and then locked, the locking member is urged to continue to move to the left toward the unlocked position under the impact and rebounds to the locked position, however. In any case, unintended movement from the unlock position to the lock position does not occur. Thus, in use, the locked position is substantially deeper than the unlocked position of the connecting member 300 from the striker 10.

Selective Electric Lock Two alternative configurations for motorized lock and unlock are described with reference to FIGS. Each configuration includes two claw release levers 700, 800 for connection to external manual operations such as internal and external door handles, each of which generally corresponds to the claw release lever 255 described in connection with FIG. . Each pawl release lever is selectively coupled to the pawl 20 by its own rotational coupling coupling member 300, 400 and 350, 450. Each such rotary coupling member comprises a lock member 300, 350, which is connected to a rotary slide member 400, 450, respectively, which corresponds to the correspondence described above in connection with FIG. It has functions similar to elements. These are arranged around a common pivot 21, provide maximum compactness and simplicity, and allow a claw release lever with a sufficient ratio to the claw to be accommodated in the housing It is.

  In addition, each latch device comprises a separate lever 900, which is connected to an external control mechanism via a cable 901, where the external control mechanism is used for the rear door or the front door. Depending on whether it is used for a door, it may be a child safety switch or an internal door knob. Another lever 900 has a pivot at 902 in the housing and is connected to a lever arm, which has an end pin 903 connected to a suitable one of the rotary coupling members.

  In the configuration of FIG. 25, the locking members 300 and 350 have respective protruding pins 304 and 354 that engage with the cam pins 501 on the rotational positioning drive member 500. In FIG. 25, the locking member is driven independently in the opposite direction, while in the configuration of FIG. 26, the locking member can be driven integrally and can be reciprocated in direction D7 or D8, however, the locking member Can be driven independently as an alternative method. The latching device of FIGS. 25 and 26 is sufficiently receptive for use with a child safety locking device and / or emergency door opening device and provides selective engagement with either or both external door handles. It is like that. It can also be integrated with an electric locking device controlled by the same electric motor or different motors.

  In the case of FIG. 25, for example, the front door is used, and the external door handle is connected to the claw release lever 700 via the cable 701 and can be locked by the lever 900 by the internal door knob. The internal handle will actuate lever 800. For the rear door, the door handle connection is reversed and the lever 900 overlaps, otherwise it can be used as a mechanical child safety lever.

  The operation of the configuration of FIG. 25 is as follows. The rotary coupling members 300, 400 drive the lugs 410 and 420 between the illustrated leftmost position and the rightmost position where the lug 420 is away from the notch 803 and the lug 401 is away from the notch 453. The lug 420 is permanently engaged with the jaw of the fork 259 on the pawl 20.

  The rotary coupling members 350 and 450 include a lug 451 on the left side that can be driven clockwise by a notch 702 on the claw release lever 700. As described above, the claw release lever is also rotatably connected to the lever 900 by the pin 903. The rotary sliding member 450 forms a notch 452 that is driven clockwise by a lug 802 on the claw release lever 800. Further, the rotary sliding member forms a notch 453, and this notch drives the lug 410 of the other rotary sliding member 400 at its leftmost position.

  The lever 700 drives the lugs 451 and 420 only in the illustrated position. If the rotary sliding member 450 is moved to the left, the lug 451 is no longer connected to the notch 702 and the lever 700 is neutralized.

  Driving the lever 800 through the notch 803 directly drives the lug 420 only when the rotary sliding member is in the leftmost position shown. As a result, the nail 20 is driven.

  Whenever the rotary coupling members 350, 450 are in the neutral leftmost position (not shown) that neutralizes the lever 700, the action of the other release lever 800 with the lug 802 acting on the notch 452 of the rotary sliding member 450. It automatically returns to the illustrated coupling position. Thus, when the inner door handle is actuated on the door latch neutralized by the child safety lever, subsequent actuation of the inner door helps open the door. In other words, the operation of the external handle overrides the child safety function. Similarly, this arrangement provides an emergency door lock override, which causes the lever 800 to lift the internal doorknob connected to the lever 900 when operating the internal handle.

  The configuration of FIG. 26 operates in the same manner as the configuration of FIG. The difference is that both rotary sliding members 400, 450 cooperate with the claw fork on the right side of the device. Corresponding parts are denoted by the same reference numerals. FIG. 26 (B) schematically shows the detailed structure on the right side.

  This arrangement eliminates the need for a mechanical child safety lever since the selective operation of the internal door handle can be controlled electrically from the central electronic control unit. The use of the outer door handle as a mechanical override mechanism allows the inner handle to be opened, which is beneficial for use as a police vehicle and child safety.

  This configuration achieves double locking, such as by neutralizing the internal doorknob connected to the lever 900 as in FIG. Thus, a single electric motor can control the double lock, providing selective locking of the internal and external handles and the child safety control. The electric child safety lock is possible without the provision of any independent mechanical device by selective independent control of the internal door handle.

  Existing door latches require a large number of mechanical units due to the double lock and usually employ two motors.

Continuation of lock / unlock function after temporary blocking by mechanical door handle operation The claw release lever 700 of FIGS. 25 and 26 represents the neutral position at 700A and the complete operation position at 700B in FIG. . In operation, the corresponding rotary coupling lug 420 at position d can only be partially driven from its unlocked neutral position 420A toward the fully locked coupling position 420C. This is because the lug abuts against the edge of the lever 700 at 420B. Once the door handle is released, the lever returns to position e and the lug 420 is free to move from 420B to the fully connected position 420C. The electric motor can be re-powered under the control of the central lock control unit 90 in order to achieve a continuous movement from B to C to the left even after the first attempt has been blocked. However, an alternative mechanical device is to provide a mechanical elastic bias that guides the lug from 420B to 420C. Preferably, an over-centered spring device is provided, the unstable center position of which corresponds to the middle of the lug position between positions 420A and 420C, just to the right of the intermediate position 420B where the lug engages the lever 700. is there. Thus, the lug is biased to the right until it moves to the intermediate position and beyond this intermediate position, it is biased to the left. Such over-center spring devices are well known and can typically employ torsion springs whose ends are connected to a lug and a housing, respectively.

  An alternative construction of the rotary sliding member 400 and claw 20 of FIGS. 25 and 26 is shown in FIG. The forks are not formed on the claws but on the rotary sliding member 400, and the lengths of the fork arms 430 and 431 are changed. This configuration facilitates sealing and separation of the rotary coupling member and lever, and the rotary coupling member and lever can be integrally sealed with the drive gear and the motor. In the arrangement of FIG. 28, the pawl and latch bolt are more easily separated from this sealed assembly because pin 20A can pass on pivot 21 through a sealable opening in the housing. This provides better noise protection and can improve the life of the latch actuator by eliminating grit and other abrasive materials.

Electro-Mechanical Child Safety Device The electro-mechanical child safety device used with the above latch device is shown in FIG. Another electric motor 70 drives a lever 194 pivotally attached at 195 and is pivotally attached to the lever 194 through a slot 193 at a location 192 through a sliding block 191. The block 191 is constrained to move linearly and is driven by a lead screw 198 driven by a motor through a reduction gear device. The lever 194 has a pin 196 at its pivot end, and the pin 196 is connected to the actuating lever 197, which can reciprocate linearly between positions c and d, thereby providing a child safety device. Drive. As described above, the actuating lever selectively connects the child safety device to the pawl and selectively releases the internal handle. The electric drive eliminates the need for a mechanical child safety lever or switch in the rear door latch.

Combination type electric lock and door opening and closing The configuration shown in FIGS. 30 to 38 is a single electric motor, and the electric door lock and unlock (central lock) and latch device for door opening and / or closing etc. It controls independent functions. Several independent innovations are disclosed for other configurations.

  The latch device of FIG. 30 discloses a rotary positioning drive member 50 having a single cam pin 30, which has two neutral positions Np1 and Np2 and is also provided by a spring 1009 which also absorbs shocks. The spring is biased to the position. Controlled actuation in directions D1 and D2 causes independent actuation of the lever arm 1001 for door locking and the cam finger 1004 of the reciprocating mechanism 1006. The electronic lock is achieved by rotating the lever 1001 in the direction D11 or D12 against the return torsion spring 1002 and appropriately operating the pair of lock members 300 and 350 together. As shown in the figure, the cam 1003 of the lever 1001 rotates from the neutral position C to one of the extreme positions C1 and C2 depending on the rotation direction of the cam pin 30.

  The opening of the door is accomplished by a reciprocating body 1006 having a contact surface 1005 acting on the lever 1008 of the pawl 20. The door is closed by the contact surface 1010 at the lower end of the reciprocating body, and the lower end of the reciprocating body abuts on the latch bolt extension 37 to move the latch bolt extension from position B to position B1. As shown, the cam finger 1004 moves between the neutral position Np and the extreme positions P1 and P2. As before, the reciprocating body is controlled by a tension-compression coil spring 1007.

  The configuration of FIG. 31 shows how a single cam finger 1012 on the rotary positioning drive member 50 controls three functions. The single lever 1001 shown in FIG. 30 is replaced with two levers 1010 and 1011 arranged at equiangular intervals around the rotating member 50. The cam finger 1012 has three neutral positions Np1, Np2, and Np3, and the cam finger is biased by a spring (not shown) with respect to these positions. This allows independent control of the two locking members 300 and 350 shown.

  Another embodiment is shown in FIG. 32, in which the fourth actuating member is selectively driven by the cam fingers 1012, and the four actuating members 1020 to 1023 are spaced around the rotating member 50 at equal intervals. The This allows a single drive motor to selectively lock the two handles as shown in FIG. 31 and to control auxiliary functions such as opening and closing the electric door and child safety. In the modification shown in FIG. 32, different cams 1012 can be arranged on different camshafts on the camshaft (not shown) in the axial direction of the rotating member 50, and the flexibility of multiple functions can be enhanced.

  Another variation is shown in FIG. 33, which is particularly suitable for rear door or trunk latches. A single cam pin 30 selectively drives the pawl 20 through the rotating lever 1030, which is mounted coaxially with the pawl and arranged with a hanging flange 1031 that drives the pawl in direction D3 but in direction D7. Only rotates freely and does not drive the nails. Thus, the cam pin 30 can rotate clockwise in the direction D6, and the lever 1030 rotates without being blocked by the claw. The cam pin 30 also drives the lever arm 1034, thereby driving the lock member 300, which is also coupled to the key mechanism via the link 1033. The lock mechanism connects the handle or knob to the claw 20 via the link device 245.

  As in the other embodiments, the rotating member 50 is spring-biased to a neutral position by a wavy rotating cam surface or the like, and the leaf spring 1037 is urged in the radial direction against the wavy rotating cam surface.

  FIG. 34 illustrates how the cam pin 30 can be arranged to drive the two sliding lock members 300 and 350 through appropriate pins or protrusions 304 and 354. FIG. The protrusion 354 can be moved between positions A, A1, A2 and A3 by the cam pin 30. Protrusion 304 is movable between positions B, B1, B2 and B3 accordingly. The stable positions of the protrusions 304 and 354 are positions on the broken lines indicated by A1, A2 and B1, B2, and the protrusion is displaced between these positions by the cam pin 30 and returns to these positions after passing the cam pin 30. In order to allow the cam pin 30 to pass through, the projections are elastically movable outward toward their respective extreme positions A, A3, B and B3. Illustratively, the elasticity is achieved by arranging the protrusions on the locking member 300 to take the form of a toggle 1050 as shown in FIG. 35, the toggle being pivotally attached at 1052 and by a torsion spring 1053. Biased to a central position, its spring is located on the pivot and is held by a fixed block 1054. The toggle or finger 1050 is rotationally displaced toward P1 and returned to the neutral position P by the spring arm 1051. Similarly, the toggle is displaced to the position P2 and returned to the neutral position by the spring arm 1055.

  Other forms of elastic forming are possible as well. As shown in FIG. 36, the cam pin 30 is fixed and rides on a V-shaped leaf spring 1070, where the leaf spring is held in the box-shaped portion of the actuator 1080. It is one part. Alternatively, as shown in FIG. 37, the pin or button 30 is arranged to slide within the actuator housing of any of the rotating members 50, thereby allowing the pin or button to pass through the cooperating cam. Immerse yourself to allow.

  In the configuration of FIG. 38, the rotating cam 1083 engages flexible elongate arms 1081 and 1082, which are elastically deformable in the radial direction of the rotating member 50, so that after the operational phase of rotation. The passage of the cam 1083 is allowed.

Key Actuating Mechanism The operation of the key mechanism suitable for use with the latch device shown in FIGS. 25 and 26 will be described with reference to FIGS. A typical cylinder-type key mechanism has a rotation output, and this rotation output needs to be converted into a linear displacement of the lock members 300, 350 and the like. This is achieved by a special form of cam disk 5000 arranged to be driven by a key mechanism. In the configurations of FIGS. 39 and 41, the cam surface causes the opposing linear movement of the locking member, and in the configurations of FIGS. 40 and 42, the direction of movement is the same. In each case, this configuration allows independent mechanical actuation of the same locking member.

  As shown in FIGS. 39 and 41, the cam disk 5000 has a wedge-shaped cam surface in each of its four quadrants Q1 to Q4, and the cam surface extends from a low position to a high position in the plane of the disk. The high position is sufficiently separated from the surface of the disk by a locking member in the radial direction to displace the required linear distance. In this example, the quadrant facing the diameter of the cam surface is the opposing surface of the disk. Corresponding to the examples of FIGS. 40 and 42, the opposing quadrants of the cam surface are on the same surface of the disk. 39 and 40, regions D3 and D4 represent directions orthogonal to the plane of the disk 5000, and the lock member moves with respect to this plane.

  In operation, the key drives the disk 5000 a quarter turn clockwise or counterclockwise to lock or unlock, and this movement is the corresponding linear movement of the locking members 300, 350 by tilting the quadrant Is converted to

  The locking device is also shown in FIG. 43, which corresponds to the system of FIGS. 39 and 41, where the locking member moves in the opposite direction when actuated. The adapter 2007 with a splined cylindrical recess 2006 is connected to the conversion disk 5000, which can be driven by a key 2001 with a splined end 2005. In this configuration, because of the arcuate spline 2005, angular tolerances are allowed in the cone 2003. Key rotation in direction 2004 drives adapter 2007, which drives disk 5000 in the appropriate direction of rotation.

  For added safety against theft, the cylindrical sleeve 2002 is preferably placed along the shaft of the key 2001 and covered with a stick-resistant material such as Teflon, silicone or adhesive grease. . This prevents saw teeth from biting the shaft.

  In an alternative embodiment, a conventional key mechanism is connected to the latch by a cable or rod or lever.

  The cylinder key as shown in FIG. 44 (A) is provided with a radial arm 2011 connected to the key shaft 2001. In such a rotation lever 2011, by providing a diamond opening 2010 (FIG. 44 (B)) or 2100, 2200 (FIG. 44 (C)) on the end flange of the locking member, A device as shown in FIG. 44 (C) can be used to drive the respective locking members 300, 350. The edge of the rhombus opening behaves as a cam surface during the rotation of the lever 2011, and drives the locking member in an appropriate direction in the same direction as FIG. 44 (B) or the opposite direction of FIG. 44 (C). In the configuration of FIG. 44 (D), the key lock mechanism 3003 is provided with a radial cam 3004, which is engaged in the notch 3005 of the lever 3001, and rotates 3006 in the direction 3007. Lever 3001 includes a protrusion that engages a notch formed in an actuation lever 3002 that is linearly movable in direction 3008. Naturally, this is one of the locking members 300 and 350. In the case of two locking members, the two levers 3001 are installed on the same rotating shaft 3006.

Double Lock As a modified example or an additional example of the electric double lock device described above, FIG. 45 shows a mechanical configuration. The key mechanism lever 451 moves in parallel with the internal door knob mechanism 452, and the ends of these mechanisms are connected by a pivot lever 453 pivotally attached to both mechanisms as shown. A torsion spring 455 mounted on the pivot of the lever 453 on the key mechanism 451 has two rims, which are arranged around the stationary guide 456 and extend around the cam pin 457. Rotation of lever 453 from the neutral position in FIG. 45 in either direction of rotation tensions the spring and the appropriate rim of the spring acts on pin 457, returning it to the neutral position. The protrusion 460 on the key mechanism 451 prevents the lever 453 from rotating beyond the illustrated position AA.

  The two parallel guides 458 and 459 are fixed to the latch housing, and their lengths are equal, but are shifted in a linear direction as shown.

  In the unlocked position shown in FIG. 45, the door can be locked by a key mechanism that moves in the direction D1, and at this time, the pin 457 follows the line BB. The door can only be unlocked by following the opposite with a key mechanism. Even if an attempt is made to unlock the internal door knob 452 by lifting it in the direction D3, the lever 453 rotates in the direction D4, and the pin moves to the position 457A. At this position, the pin contacts and is restrained by the right guide rail 458. . This constitutes a double lock, deadlock or super lock.

  However, when the door is locked by the internal door knob 452, the lever 453 is rotated in the direction D2, the pin follows the path AA with respect to the left side of the guide rail 459, and the pin 457 slides with respect to the guide rail. . The guide rail 457 extends long downward and does not prevent the pin 457 from returning along the line AA.

  The claw release lever 460 or the actuator itself can be configured as shown in FIG. During manufacture, the sheet metal 460 forms a transverse flange 469 at one end, which has circular openings 461 and 462, which are laterally aligned on the lever, at both ends. Formed in the part. A slot 463 is formed in the flange 469 and opens the opening 462 outward. During manufacture, the flange 469 is bent at 467 and 468 to face the main portion 460 as shown, where it is aligned with the openings 461 and 462. To join the finished lever of the cylindrical nipple 466 at the end of the cable 465 such as a Bowden cable, the nipple is inserted into the opening from the flange side, the cable 465 is inserted through the slot 463, and the cable is rotated clockwise. And can be achieved by locking in its position in a freely rotatable manner. It is also possible to restrain the cable nipple when the flange is bent during manufacture. This avoids the need for rivets and release lever molds.

Latch Actuator Housing As described above, the latch actuator can be formed into a compact box-shaped housing. As shown in FIG. 47, the housing is composed of two opposed end plates 3017 and 3018 and a side wall 3027. This arrangement is secured to the door frame 3023 by suitable bolts 3024, 3025 and 3026, which are for the pivot 30 and the latch bolt 11 for the shaft 3019, pawl 20 and other mechanisms 3020, 3021 and 3022, respectively. Screwed into the pivot 15. The pivot shafts 21 and 15 are provided with upward projections extending through the plate 3017 and are provided with radial engagement portions 3015 and 3028, respectively.

  The elongate closure plate 3010 includes keyhole shaped openings 3012 and 3013 that connect with protruding pivots 3015 and 3028. During manufacture, the elements of one latching device are assembled as shown, the face plate 3017 is inserted on three spindles, and the closing plate 3010 has a large circular opening in each keyhole 3012 and 3013 with an enlarged portion. Positioned to pass 3015, 3028. In this respect, the corresponding opening 3011 in the closing plate is slightly offset from the axis of the spindle 3019 as shown. The closure plate 3010 can then be slid in the direction A on the face plate 3017 and locked in place. The interior of each keyhole slides to hold the respective spindle on pivots 21 and 25. The closure plate then strikes the enlarged portion or stud 3015 and 3028. At this point, the opening 3011 of the closing plate reaches the axis of the spindle 3019, and then the closing cap 3014 is pushed into the corresponding opening of the opening 3011 and the face plate 3017 so that it does not slide. Can be fixed to.

  This configuration allows for a non-destructive disassembly of the latch device by simply removing the cap 3014, sliding the closure plate 3010, then removing the closure plate and dismantling the remaining portion of the latch assembly. . As a result, the failed part can be replaced at any time.

  A dedicated closure plate can be provided at each end of the latch housing.

Multiple Locking Key Mechanism As shown in FIG. 48, a single key mechanism 481 with an exit radial lever 482 rotatable in either direction D1 or D2 is placed through respective cables 483 and 484; Two different locking mechanisms 485 and 486 can be actuated, respectively. Bowden cables are preferred, but alternative linkages are of course possible. By way of example, a key mechanism on a vehicle door may be coupled to the door and to different door latches via respective cables. However, the key mechanism may be anywhere on the vehicle body accessible from the outside. This makes it possible to reduce the number of required key mechanisms and to make the door more streamlined. As a matter of course, the present invention is not limited to the door but can be applied to other closing devices, and three or more locks can be connected to the same key mechanism via respective cables. Furthermore, the present invention is a system that can be adapted to allow the key mechanism to be spaced from the latch.

Clutch mechanism As shown in FIG. 49, the electric drive for the door opening and closing mechanism can be released by the operation of a mechanical actuator such as a door handle. This ensures that the mechanism does not shut down in the event of a power system failure. The motor output spindle 60 </ b> A drives the rotation output drive unit 60 from the spindle 492 extending from the housing 491. The rotation drive unit 60 is connected to a spline gear 496 which meshes with an internal spline connection gear 498. The connecting gear 498 forms a conical cam surface 497 and is axially spring biased to mesh with an exit gear 1490 that drives a rotating cam unit 1493, which unit is a first cam that operates a pawl by a link arm 1491. 1495 and a second cam 1494 for driving the latch bolt 11. The connecting gear 498 selectively engages the final output gear 1490 by mutually opposing teeth at 499 in meshing engagement. The connecting gear 498 is axially separated from the engagement with the output gear when driven by the link arm 495 whose one end is also visible in FIG. The flange 494 on the link arm forms a wedge-shaped cam 4941 that cooperates with the conical cam surface 497 to drive the connecting gear 498 axially and pressurize the spring. The link R495 is elastically biased by a spring 493 toward the neutral position in FIG.

  Thus, the link arm selectively disengages the clutch, preventing the electric drive force from interfering with the mechanical drive force, and vice versa.
