Description

Opening and closing device for vehicle door and manufacturing method thereof

technical field

The present invention relates to an opening and closing device for a vehicle door and a manufacturing method thereof, and more particularly, to an opening and closing device for a sliding door of a vehicle.

Background technique

A conventional and typical opening and closing device for a sliding door of a vehicle has: front and rear closing door latch units respectively provided on the front and rear sides of the vehicle door for keeping the door closed; A door latch unit (full door latch unit); and an operating force transmission mechanism (remote control mechanism) functionally connecting the outer and inner door handles of the vehicle door to each latch unit so that by means of the operating force of the door opening handle The latch unit is released (see JP2012-072645, JP2013-253370, JP2007-85138). The operation force transmission mechanism includes: a lock mechanism that cuts off the operation force transmission path extending from the outward opening door handle and the inward opening door handle to the door closing latch unit; and a part (or the whole) of a power release mechanism by means of Motor power releases each latch unit.

In the door opening and closing operations, the inward opening door handle of the sliding door of the vehicle is operated in two directions opposite to each other. The inward opening door handle is respectively connected to the door opening lever connected to the door closing latch unit and the door closing lever connected to the door opening latch unit via different paths by means of connection means. When the inner door handle is operated in the door opening direction, the door closing latch unit is released via the door opening lever, and the vehicle door is placed in an openable state. When the inner door handle is operated in the door closing direction, the door opening latch unit is released via the door closing lever, and the vehicle door is placed in a closable state.

On the other hand, the outward opening door handle of the sliding door of the vehicle is operated in one direction, and the door opening and closing operations function in the same manner. Therefore, when the swing-out door handle is operated, all three latch units are released. This arrangement is a standard configuration used from the standpoint of user convenience and manufacturing economy.

As described above, in the door opening operation and in the door closing operation, the inward opening door handle is operated in opposite directions. Therefore, the door opening lever or the door closing lever is generally provided with a slit for allowing the lost motion of the inward opening door handle to move in both directions. Lost motion means the margin of relative movement allowed for one element before it engages or abuts another element.

Furthermore, in conventional opening and closing devices for vehicle doors, the operating force of the outward opening door handle is typically transmitted to the door closing latch unit via the door opening lever and to the Door open latch unit. Therefore, in order to prevent the operation of the outer door handle from interfering with the operation of the inner door handle, the door opening lever or the door closing lever is generally provided with a slit for lost motion, and the length of the slit is greater than that required to allow the two-way operation of the inner door handle. The length is long.

As an example, FIG. 10 schematically shows a door closing lever A disclosed in JP2012-072645. When the inward opening door handle is operated in the door closing direction, the bent end B of the rod abuts against the door closing lever A, and the closing door lever A is rotated clockwise to the release position as shown by the dashed line, and the door latch unit is opened Released by closing lever A. The travel distance of the bent end B is shown as L1. On the other hand, when the inward opening door handle is operated in the door opening direction, the bent end B of the rod travels a distance L2 within the lost motion slit C, thereby allowing operation of the inward opening door handle.

When the outward opening door handle is operated, the door closing lever A in FIG. 10 rotates clockwise in the same manner as the door closing operation of the inward opening door handle, and releases the door opening latch unit. At this time, the slit C of the door closing lever A is moved by a distance L1 relative to the bent end B (the travel distance of the bent end B relative to the slit C at the moment when the handle of the outward opening door is operated is not exactly equal to that of the inward opening door L1 at the moment when the handle is operated, but can be considered functionally the same). This means that the length of the lost motion of the slit C (the length of the slit C) is used or reduced by the distance L1.

When the inner door handle is operated in the door opening direction at the moment when the lost motion of the slit C is used, that is, when the operation of the outer door handle using lost motion and the door opening operation of the inner door handle are simultaneously performed, the bending End B will move relative to slot C a distance "L1+L2". This means that the length of coverage distance L1 or L2 (whichever is larger) is insufficient for the lost motion of the slot C and that the lost motion of the slot C requires covering the length of L1+L2. Accordingly, the length of slit C in Figure 10 will be greater than that required to cover bi-directional operation of the inward opening door handle.

As will be understood from the above explanation, a conventional opening and closing device for a vehicle door has a door opening lever or a door closing lever provided with a slit for lost motion, and the arm portion of the lever provided with the slit must be formed sufficiently. large to accommodate the slit.

Additionally, the bent end of the rod will be connected to the slot via a resin snap when the lost motion is provided by the slot. However, the assembly of the robot may be delayed due to the work of establishing the connection.

Contents of the invention

An object of the present invention is to provide an opening and closing device for a vehicle door which makes it easy to set lost motion when the operation of the outward opening door handle and the door closing operation of the inward opening door handle are performed simultaneously, and which opens and closes The equipment can limit the increase in the size and weight of the member.

detailed description

An opening and closing apparatus for a sliding door of a vehicle according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a vehicle door 11 provided with an opening and closing device 10 . The vehicle door 11 is slidably attached to a vehicle body 12 . The vehicle body 12 is provided with a power sliding device 13 that moves the vehicle door 11 in the front-rear direction by means of motor power to open and close the vehicle door 11 .

A front striker 15 is provided at the front end of the door opening 14 of the vehicle body 12 , and a front door close latch unit 16 engaged with the front striker 15 is provided at the front end of the vehicle door 11 . A rear striker 17 is provided at the rear end of the door opening 14 of the vehicle body 12 , and a rear door close latch unit 18 engaged with the rear striker 17 is provided at the rear end of the vehicle door 11 . These latch units are provided with a well-known latch/ratchet mechanism and engage with strikers to keep the vehicle door 11 closed.

The vehicle door 11 further includes a door opening latch unit 19 having a latch/ratchet mechanism. When the vehicle door 11 is moved to a predetermined fully open position in the door opening sliding operation, the door open latch unit 19 is engaged with the fully open door striker 20 fixed to the vehicle body 12, and the door open latch unit 19 holds the vehicle door 11 in the fully open position.

The swing-out door handle 21 is provided on the outside of the vehicle door 11 , and the swing-in door handle 22 is provided on the inside of the vehicle door 11 . An operation force transmission mechanism 23 (also referred to as a remote control unit) is provided in the inner space of the vehicle door 11 . The outward opening door handle 21 and the inward opening door handle 22 are functionally connected to the front closed door latch unit 16 , the rear closed door latch unit 18 and the open door latch unit 19 via the operating force transmission mechanism 23 . By the operation of the door open handles 21, 22, the front closed door latch unit 16 and the rear closed door latch unit 18 are disengaged from the strikers 15, 17, respectively, and the vehicle door 11 is placed in an openable state. By the door closing operation of the inner door handle 22, the door open latch unit 19 is disengaged from the full door striker 20, and the vehicle door 11 is placed in a closable state.

FIG. 2 shows a side view of the operation force transmission mechanism 23 seen from the inside of the vehicle. A handle housing 25 is attached to the base plate 24 of the operation force transmission mechanism 23 . The swing-in door handle 22 is pivotally supported by the handle housing 25 via a longitudinal axis 26 and allows the swing-in door handle 22 to rotate about the longitudinal axis 26 in two opposite directions (ie, in the door opening direction and in the door closing direction). An inner lock button 27 is provided at a lower portion of the handle housing 25 .

The swing-in door handle 22 has a first leg 28 and a second leg 29 . The left end of the link 30 is located on the locus of the rotating first leg 28 , and the door closing lever 31 is pivotally connected to the right end of the link 30 . The door closing lever 31 is connected to the door opening latch unit 19 via a connection cable 32 . When the swing-in door handle 22 is operated in the door closing direction, the first leg 28 abuts against the link 30, pushes the link 30 to the right, and rotates the door closing lever 31 clockwise toward the release position. Accordingly, the open latch unit 19 is released, and the vehicle door 11 is placed in a closable state. 9 shows various levers for operating the force transmission mechanism 23, where "C" indicates a door closing operation, "O" indicates a door opening operation, and "L" indicates a locking operation in which the door opening operation is made inoperable.

The second leg 29 of the inward opening door handle 22 is connected to the left end of the opening cable 33 and the cable end 34 is attached to the right end of the opening cable 33 . The cable end 34 has a spherical shape with a larger radial dimension than the opening cable 33 .

At the center of the base plate 24 , an inner door lever 35 is pivotally supported by a shaft 36 . A guide holder 38 made of resin is engaged with the curved engaging part 37 of the inner door lever 35 . The guide holder 38 has a bottomed cup shape having an open end at a side away from the inward opening door handle 22 through which the guide holder 38 can accommodate the cable end 34 . An aperture 39 for opening the cable 33 is provided on the bottom side of the guide holder 38 engaged with the curved engagement part 37 . The aperture 39 at the side facing the inward opening door handle 22 is sized to allow the passage of the opening cable 33 but not the cable end 34 . In this way, the guide holder 38 and the cable end 34 required to provide lost motion are constructed very simply.

The cable end 34 is housed in the guide holder 38 in the standby state. When the inner door handle 22 is operated in the door opening direction, the cable end 34 is pulled to the left (i.e., toward the inner door handle 22), and the cable end 34 rotates the inner door lever 35 in the door opening direction (counterclockwise) . The door opening rotation of the inner door opening lever 35 is transmitted to the connection lever 41 via a child pin 40 , and the rotation of the connection lever 41 is then transmitted to the release lever 43 via the lock pin 42 . The release lever 43 is connected to the front door latch unit 16 and the rear door latch unit 18 via cables. Therefore, by the door opening operation of the inner door handle 22 , the front close door latch unit 16 and the rear close door latch unit 18 are released.

The guide holder 38 is attached to the opening cable 33 in advance, and thereafter is fixed to the bending joint part 37 . The process of attaching the guide holder 38 is rather easy as it can be done simply by engaging the guide holder 38 with the fork-shaped curved engagement part 37 by means of a robot.

When the inner door handle 22 is operated in the door closing direction so that the door closing lever 31 is displaced to the release position, the cable end 34 connected to the inner door handle 22 via the opening cable 33 is moved to the right, and as shown in FIG. 4 alone protrudes from the opening of the guide holder 38 to the right. This separate movement of the cable end 34 provides lost motion relative to the inner door lever 35 and prevents the inner door lever 35 from rotating in a clockwise direction. Furthermore, since it is not necessary to provide a slit for guiding the rightward movement of the cable end 34, the size and weight of the inner door lever 35 can be reduced.

The swing-out door handle 21 is connected to a swing-out door lever 45 via a rod 44 . The swing-out lever 45 is pivotably supported to the base plate 24 via the shaft 36 , and is rotated in the door-opening direction (counterclockwise) by the operation of the swing-out handle 21 . The door opening rotation of the outward opening lever 45 is transmitted to the protrusion 47 of the connection lever 41 via the stepped portion 46, and then from the connection lever 41 to the release lever 43 via the lock pin 42, and thereby releases the front closing door latch unit 16 and the rear closing door latch unit 16 and the rear closing door. Door latch unit 18 .

As shown in FIG. 4 , assuming that by the door closing operation of the inward opening door handle 22 , the outward opening door handle 21 is operated when the cable end 34 alone protrudes rightward from the opening of the guide holder 38 . As described above, as shown in FIG. 3 , the outer door opening lever 45 is rotated in the door opening direction (counterclockwise), and the stepped portion 46 presses the protrusion 47 of the connecting lever 41 and rotates the connecting lever 41 in the counterclockwise direction. The inner door opening lever 35 is then largely rotated in the door opening direction (counterclockwise) in FIG. 4 via the protrusion 47 . However, as will be easily understood from these figures, when the inner door lever 35 is rotated counterclockwise, the guide holder 38 attached to the inner door lever 35 moves only leftward leaving the cable end 34 . Accordingly, a sufficient space for lost motion required when the inward opening door handle 22 and the outward opening door handle 21 are simultaneously operated is ensured between the guide holder 38 and the cable end 34 without requiring an additional mechanism.

The inner locking button 27 is connected to a locking lever 49 via a button rod 48 ( FIG. 6 ). The locking pin 42 is connected to a slot 50 in the right arm of the locking lever 49 and a fork 51 in the lower arm is connected to a locking actuator 52 . A bent connection portion 53 at the right end of the button lever 48 is attached to a lever holder 54 holding the locking lever 49 of the button lever 48 . When the locking lever 49 is rotated in the locking direction, the locking pin 42 is moved to the lower part of the slot 43a of the release lever 43 (shown with a dashed line in FIG. 9 ), thereby preventing the release lever 43 from being rotated by the locking pin 42. . Therefore, the door opening operation of the outward opening door handle 21 and the inward opening door handle 22 becomes inoperable.

The lever holder 54 has an opening formed in a central region, a U-shaped or V-shaped peripheral wall 55 surrounding the opening of the button lever 48 . On the focal point side of the peripheral wall 55 , an insertion hole 57 into which the tip 56 of the curved connection portion 53 is inserted is provided. As shown in FIGS. 6-8 , a locator 59 having a holding plane 58 parallel to the rotation plane of the lock lever 49 is provided along a part of the peripheral wall 55 and faces a part of the opening. The locator 59 is dimensioned to allow approximately half of the opening of the rod holder 54 to be used as an insertion aperture 60 through which the curved connection 53 is inserted. The surface of the positioner 59 is provided with a guide plane 61 inclined downward toward the insertion aperture 60 .

The handle housing 25 to which the inward opening door handle 22 (and the opening cable 33 ) and the inner locking knob 27 (and the knob lever 48 ) are pre-attached is fixed to the base plate 24 by means of screws. The button lever 48 is guided along a portion of the opening of the lever holder 54 that does not face the locator 59 . At this time, the button lever 48 is connected to the inner lock button 27 only in the locked position at the left end. The curved connection 53 on the right end is unstable but faces the aperture 60 of the locking lever 49 in the locked position so that it is almost ready to be inserted into the insertion aperture 60 . The curved connection portion 53 is then smoothly guided into the rod holder 54 via the insertion aperture 60 by means of the guide plane 61 and the peripheral wall 55 of the positioner 59 , and the tip 56 of the curved connection portion 53 is inserted into the insertion hole 57 . Thereafter, as shown in FIGS. 3, 7-8, by switching the locking lever 49 to the unlocked position, the curved connection portion 53 is moved into the holding space 62 below the positioner 59, and the button rod 48 is reliably connected to the Lock lever 49 .

The lost motion provided by the guide retainer 38 and the cable end 34 in the present invention can also be applied to the door closing lever A in FIG. 10 . The invention can easily be applied to any movable element that can be moved in one direction by both the operation of the outward opening door handle 21 and the operation of the inward opening door handle 22 and preferably requires lost motion when rotated in one direction.
