Description

  The present invention generally relates to door latches, and more specifically, to an automobile door lock unit that holds a grip portion at a plurality of positions using a single claw portion and a rotation prevention lever.

  A latch mechanism is usually used for a lock unit used in an automobile side door. The latch mechanism is known as a catch and receives a grip bolt or striker that is typically located on a window pillar of a car door frame. When the slot of the latch housing is aligned with the recess of the grip portion, the grip portion moves to the unlocked position by urging. When the door is closed, the striker enters the recess through the slot and rotates the gripping portion to the locked position. In this unlocked position, the striker is held in the recess by a claw, and the claw prevents the gripper from rotating in the direction of the unlocked position. In general, the claw portion is strongly biased in the direction of the grip portion, and these two contact surfaces are biased in a direction repelling the acceleration force and disposed at a predetermined angle in order to resist strong acceleration force. Has been. The latch housing is generally made of plastic, and a portion other than the slot region can be sealed with a cover. Such lock units generally include at least one release lever (eg, an inner or outer door handle) and a lock mechanism that can be displaced (eg, a lock cylinder provided at or within the outer door handle, Or a slide button disposed in the window glass region of the door). In such a case, when unlocking the lock mechanism, the inner or outer door handle is interlocked via the mechanism, and the movement separates the connection between the claw part and the grip part against the urging force of the claw part. Thus, the spring-loaded gripping portion can be moved to the unlocked position.

  In general, a lock unit provided in the door, hatch or tailgate of an automobile is provided with a secondary latch engagement position in addition to the main latch engagement position. The secondary latch engagement position is a position between the main latch engagement position and the unlocked position, so that the door can be moved even when the grip portion cannot reach the main latch engagement position. The door is held closed in the secondary latch engagement position so that the door is not moved to the unlocked position, which would obviously endanger the passenger. In addition to preventing the automobile door from opening during movement, the secondary latch engagement position can also be perceived if the user does not close the automobile door with sufficient force. Normally, if the force to close the automobile door is too weak, the door is visually half-opened at the secondary latch engagement position to ensure that the door is not latched securely. Kept. By applying additional force (e.g. leaning on a car door), the latch mechanism can be pushed into the main latch engagement position and the door can be completely closed.

  When the claw portion is released from the main latch engagement position by the operation of the release lever, the claw portion suddenly moves away from the corresponding lock surface of the gripping portion, and the spring-loaded gripping portion moves at a high speed. To move to the unlocking position. The sudden movement of the locking surfaces with respect to each other results in a fairly large opening crack, which is immediately followed by a second loud noise. The second loud noise is generated when the gripping portion gives an impact at the limit locking portion when the gripping portion reaches the unlocked position. In order that the strong force urges the locking surfaces of the claw portion and the gripping portion (and also because the strong force urges the gripping portion in the direction of the restricting locking portion), the automobile door The noise generated by unlocking is very large. Furthermore, the strong impact on the claw portion and the gripping portion can damage the lock unit and significantly limit its useful life, particularly since most of the impact is generated along the lock surface.

  German Patent Application Publication No. 10 2007 003 948A1 discloses a latch mechanism having a plurality of claw portions, and the latch mechanism is required to operate the latch noise and the latch mechanism during unlocking. And reducing both of them. The lock surface and the first claw portion of the gripping portion are correspondingly chamfered and inclined to realize a smooth and gradual slide when the lock surfaces are released from each other. Since the locking surfaces are designed to reduce the synthetic shear force generated by pressing the surfaces while the gripping part is released, the force required for the operation of the locking mechanism also corresponds to it. Decrease. Furthermore, as a result of the reduced force acting on the latch mechanism, the noise introduced during unlocking is significantly reduced.

  However, since the locking surfaces are designed to slide relatively easily with respect to each other, the latching mechanism is not self-latching (ie, the locking surfaces themselves hold the gripper in place). However, a claw rotation prevention lever that holds the first claw portion at the main latch engagement position with respect to the grip portion is required. In addition, a second pawl is also required to achieve a secondary latch engagement position. In order to prevent the claw rotation prevention lever from being engaged at the secondary latch engagement position during locking, the second claw portion includes the gripping portion, the first claw portion, and the rotation. It is arranged in a plane separated from the prevention lever. When the main latch engagement position cannot be reached (for example, when the first claw portion slides away from the grip portion), the bolt extends from the grip portion to the plane of the second claw portion. By pulling out, the bolt comes into contact with the anti-rotation arm of the second claw portion in the unlocking path of the gripping portion, and the secondary latch engagement position is achieved. However, providing the second claw portion on a different plane and guiding the bolt into the grip portion is expensive from the viewpoint of manufacturing. Thus, the design with the plurality of pawls effectively reduces unlocking noise and latch actuation force, while it requires multiple different components in multiple planes of the latch mechanism. Yes, which makes the manufacture of the device complicated and expensive.

  In view of the above-described problems, the present invention provides a lock unit having a claw portion in one embodiment, wherein the claw portion is disposed between a gripping portion and a rotation prevention lever. The grip portion is rotatable about a grip portion rotation axis, and is biased in the unlocking direction toward the unlocking position of the lock unit. In this lock unit, the first concave portion of the grip portion is configured to receive the striker of the automobile. Further, the grip portion includes a second recess, and the second recess is disposed in front of the first recess in the unlocking direction. The claw portion is rotatable and biased in the direction of the grip portion. Further, the claw portion includes an anti-rotation arm, and the anti-rotation arm enters the second recess of the grip portion when the lock unit is in a secondary latch engagement position. The anti-rotation lever causes the anti-rotation arm of the claw portion to abut the grip portion at a main latch engagement position of the lock unit. A rocker lever is disposed so as to intersect the movement paths of both the gripping portion and the rotation prevention lever. When the lock unit is pushed from the secondary latch engagement position to the first latch engagement position, the gripping portion shifts the rocker so that the anti-rotation lever moves away from the claw portion. Moving.

  In a form of this embodiment, the primary latch engagement position and the secondary latch engagement position are provided on the same plane as the grip portion.

  In a form of this embodiment, the present invention provides a single anti-rotation arm for a single pawl to achieve the primary and secondary latch engagement positions. This further simplifies the design and helps ensure consistent operation.

  In a variation of this embodiment, the lock unit uses a smooth release at the lock surface to minimize noise and actuation force.

  In a variation of this embodiment, the secondary pawl is removed, making a conventional two-dimensional gripper available for drilling for primary and secondary loads.

  In this form of embodiment, the steel secondary pawl, spring, and gripping pin are removed, so the present invention provides an inexpensive, smaller and lighter locking unit.

  Furthermore, the design takes into account manufacturing tolerances so that small dimensional changes do not adversely affect the performance of the lock unit.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  Referring to FIGS. 1 and 3, the lock unit 10 according to the embodiment of the present invention is shown in a main latch engagement position and an unlocked position, respectively. The lock unit 10 includes a base plate 12 for attaching the lock unit 10 to a door, hatch or tailgate of an automobile, and a slot 14 provided in the base plate 12 is a striker attached to the automobile body. 16 is opposed. In general, the striker 16 (also referred to as a gripping bolt) is a pin or U-shaped bracket, which is attached to the partition on the rear side of the automobile door frame and extends into the door opening plane. I'm out. The door unit 10 is mounted on the opposite side of the automobile door hinge, the leading edge 13 of the base plate 12 faces the striker 16, and the components of the lock unit 10 are arranged in the automobile door. With such a configuration, when the automobile door is closed, the striker 16 enters the slot 14 of the base plate 12 and the first recess 22 of the gripping portion 20, and starts from the unlocked position (shown in FIG. 3). The grip 20 is rotated to the latch engagement position (shown in FIG. 1).

  When the striker 16 is installed on the automobile door, the lock unit 10 is attached to the automobile body, and a housing or cover is provided in addition to or instead of the base plate 12 regardless of the installation position of the lock unit 10. It will be noted that the component can be further protected.

  In one embodiment, the grip part 20, the claw part 40, and the rotation prevention lever 60 are relatively flat parts made of metal or plastic. Also, the optional housing that covers the base plate 12 and the lock unit 10 can be molded by plastic injection molding. In another embodiment, the lock unit 10 is composed of metal or a combination of metal and plastic parts.

  In FIG. 1, the automobile door is completely closed and the lock unit 10 is in the main latch engagement position. The grip portion 20 is attached to the grip portion rotating shaft 24 through the grip portion mounting hole 26 and holds the striker 16 in the first recess 22. The gripping part 20 is biased by a spring that rotates the gripping part 20 in the unlocking direction S1 around the gripping part rotation shaft 24. The gripping part 20 is latched by a rotation preventing arm 48 of the claw part 40. It is held in the engaged position. The claw portion 40 is held at a predetermined position by a rotation prevention arm 62 of the rotation prevention lever 60. The rotation prevention lever 60 is attached to the lever rotation shaft 68 through the rotation prevention lever attachment hole 69 and is adjacent to the claw portion 40. The gripping main locking portion 32 may be located on the bottom of the first recess 22 or on the outer edge of the gripping portion 20 between the first recess 22 and the second recess 30, and the claw portion 40 rotates. Contact the prevention arm 48. The contact surface 33 of the gripper main locking portion 32 and the contact surface 50 of the claw rotation prevention arm 48 (for example, by incorporating a surface having a positive angular gradient and gradually decreasing in inclination) ) The anti-rotation lever arm 62 is provided to abut against the locking portion 54 of the claw portion 40 because it is designed to slide smoothly away.

  Regardless of the relative position of the rotation prevention lever arm 62 and the claw locking portion 54, the rotation prevention lever 60 is prevented from rotating by the normal force from the claw locking portion 54 that penetrates the lever rotation shaft 68. However, it is preferable to bias the rotation prevention lever 60 around the lever rotation shaft 68 in the direction S <b> 2, and in that case, a twist in which one end is connected to the base plate 12 and the other end is connected to the rotation prevention lever 60. A spring may be used. Therefore, even if a moment acting on the rotation prevention lever 60 is generated by the force from the claw locking portion 54 (that is, even if a vertical force does not penetrate the rotation shaft 68 of the rotation prevention lever), the attachment in the S2 direction is performed. The rotation is blocked by the force, and the contact between the rotation prevention lever arm 62 and the claw locking portion 54 is maintained, thereby maintaining the position of the claw portion 40 and the gripping portion main locking portion 32. Prevents the claw part rotation prevention arm 48 from becoming free.

  In addition, the rotation of the rotation prevention lever 60 and the gripping part 20 and the claw part 40 is restricted to a preset operation range by using a locking restriction part (for example, a protruding part extending from the base plate 12). Could also do. In one embodiment of the present invention, the rotation of the rotation prevention lever 60 is limited in the clockwise direction when in the main latch engagement position, and is biased to that position by the lever spring in the S2 direction.

  In order to open the automobile door, the lock unit 10 moves the anti-rotation lever arm 62 away from the pawl locking portion 54 and past the anti-rotation lever release end 64 to thereby move the main latch engagement shown in FIG. Release from position. Preferably, the anti-rotation lever 60 is connected to an operation link that pulls in the S5 direction. Therefore, as shown in FIG. 2, the anti-rotation lever arm 62 rotates counterclockwise in a direction away from the claw locking portion 54. It becomes possible. The operating link is connected to an inner and / or outer door handle (e.g., designed as a rod assembly or Bowden cable) outside the lock unit 10, and the door handle is connected to the user by the user. It operates by opening the car door. As an alternative, the rotation of the anti-rotation lever 60 is controlled by a servo motor and operated by a switch or sensor.

  Referring to FIG. 2, the lock unit 10 is shown immediately after the grip 20 is released from the main latch engagement position. It will be noted that the release is fairly rapid since only one lever is actuated to release the gripper 20. Once the anti-rotation lever arm 62 opens the pawl locking portion 54, the gripping portion 20 is rotated by the spring force of the gripping portion 20, and the gripping portion main locking portion 32 moves along the pawl rotation prevention arm 48. The claw portion 40 moves smoothly toward the rotation prevention lever 60 about the claw portion pivot shaft 42 in the clockwise direction. Here, the rotation prevention lever arm 62 is accommodated in the concave portion 52 of the claw portion 40 adjacent to the claw locking portion 54.

  Once the gripper main locking portion 32 opens the claw rotation prevention arm 48 at the position shown in FIG. 2, the gripper 20 can freely rotate in the unlocking direction S1. As a result of the rotational speed of the gripping part 20 and the transitional curved surface of the claw part rotation prevention arm 48 and the secondary locking part 34 for the gripping part, the second recess 30 and the secondary locking part of the gripping part 20 As 34 slides past the claw rotation prevention arm 48, the lock unit 10 jumps over the secondary latch engagement position as shown in FIG. The grip 20 continues to rotate until it is stopped in the fully moved position shown in FIG. 3 by the spring plate 12 through the slot 14, by full tension of the spring, or by different locking limits. While the gripping portion 20 rotates, the spring force in the unlocking direction S1 pushes the striker 16 in the direction of the leading edge 13 of the base plate 12 through the slot 14, so that the automobile door is removed from the vehicle body. Leave. In such a method, the lock unit 10 is an automatic unlocking type because it does not require an external operating force after the gripping portion 20 is released.

  When the user closes the automobile door, the striker 16 is inserted into the slot 14 and gives an impact to the striking end 38 of the first recess 22 of the grip 20. Due to the force when closing the door, the striker 16 presses the striking end 38 of the first recess 22 so that the gripping part 20 resists the spring force in the unlocking direction S4 opposite to the unlocking direction S1. Rotate. During the initial rotation, the anti-rotation arm 48 of the claw portion 40 slides along the slide surface 36 of the grip portion 20. Similar to the release of the grip portion 20 when the door is opened, the second recess 30 and the main locking portion 32 slide and pass through the claw portion rotation prevention arm 48, thereby allowing sufficient force to As long as the door is closed, the secondary latch engagement position shown in FIG. 5 is bypassed. In such a case, the gripper 20 reaches the extended movement position shown in FIG. When the main locking part 32 of the grip part 20 opens the anti-rotation arm 48 of the claw part 40, the spring in the S3 direction sufficiently rotates the claw part 40 in the direction away from the anti-rotation lever 60, thereby preventing the anti-rotation lever arm. 62 exits the recessed portion 52 of the claw portion 40, and at this time, the spring in the S2 direction rotates the anti-rotation lever arm 62 in a direction to return to the position below the claw locking portion 54.

  In one embodiment, the anti-rotation lever 60 has a curved tip that facilitates smooth sliding along the claw recess wall 52. The claw concave wall 52 may also be inclined and preferably extends from the claw locking portion 54 toward the gripping portion 20.

  However, if the automobile door is not closed with sufficient force (ie, it is too late to close), the lock unit 10 enters the secondary latch engagement position shown in FIG. The secondary latch engagement position is a position between the main latch engagement position and the unlocking position, so that even when the main latch engagement position is not reached, the automobile door is opened during the movement to mount the automobile. It is intended to prevent the lock unit 10 from being disengaged into an unlocked position where a person may be exposed to considerable risk. The latch mechanism can be released from the main latch engagement position due to an external force applied by an automobile door compression seal, automobile vibration, automobile impact, or the like. That is, when this occurs, the latch mechanism must be in a secondary latch engagement position to avoid opening the door.

  Referring to FIG. 5, a secondary latch engagement position is shown according to one embodiment of the present invention. If it is too late for the user to close the automobile door, the second recess 30 of the gripping part 20 does not slide through the anti-rotation arm 48 of the claw part 40. More precisely, after the slide surface 36 slides and passes through the claw rotation prevention arm 48, the claw rotation prevention arm 48 is pressed into the second recess 30 of the gripper 20, thereby Presenting the secondary latch engagement position. In response to the continued closing operation of the automobile door or in response to an additional external force applied by the user or a servo motor, the gripper 20 continues to rotate in the direction opposite to the unlocking direction S1. When the gripping portion secondary locking portion 34 rotates away from the claw portion rotation prevention arm 48, the spring in the S3 direction rotates the claw portion rotation prevention arm 48 into the second recess 30 of the gripping portion 20. Thereby, the space | interval between the nail | claw latching | locking part 54 and the rotation prevention lever arm 62 opens. The absence of friction and negative tilt angle further reduces the effort of the rocker lever 70 required to move the anti-rotation lever 60.

  Referring to FIG. 6, the locking unit 10 is shown moving from the secondary latch engagement position toward the primary latch engagement position. The grip 20 has a local rocker operating body 37, and the local rocker operating body 37 is configured to shift the rocker arm 71 of the rocker lever 70 with the contact surface 74 of the rocker lever. This actuator 37 is preferably manufactured in the current plastic overmold of the gripping part 20. The operating body may be manufactured from a pin deformed by steel, plastic, die-cast, or excavated. In this embodiment, the rocker lever 70 has a fixed pivot shaft position 73, and supplies a reciprocity correcting force against the spring force in the S <b> 2 direction by the rotation prevention lever operating portion 72. The pivot shaft 73 of the rocker lever 70 can be a fixed pivot shaft or a slide pivot shaft.

  The rocker lever 70 may be attached to a plane along with the grip 20 and the rotation prevention lever 60 by optimally using the available mounting space. The rocker pivot shaft and the operating body are in such a relationship that the rotation prevention lever arm 62 is moved from the path of the claw locking portion 54 before the claw portion rotation prevention arm 48 contacts the grip portion outlet end 31. The grip portion outlet end 31 is curved stepwise, and realizes a smooth slide with respect to the curved end of the claw portion rotation prevention arm 48. However, it is possible to use a plurality of different complementary surfaces at the exit end 31 and the claw rotation prevention arm 48, such as a flat surface curved, chamfered and inclined. And the like.

  As shown in FIG. 7, as the lock unit 10 continues to move from the secondary latch engagement position to the main latch engagement position, the grip 20 operates the rocker lever 70 using the operation unit 37. At the same time, the outlet end 31 moves the claw rotation prevention arm 48 in the direction opposite to the S3 direction.

  As the claw portion rotation prevention arm 48 slides up the grip portion outlet end 31, the rotation prevention lever arm 62 is restrained behind the claw concave portion 52. Further, the rocker operating body 37 of the gripper 20 moves beyond the engagement position with the rocker arm 71 of the rocker lever 70 shown in FIG. When the operating force from the grip portion 20 is relaxed from the rocker lever 70, the urging force applied to the claw locking portion 54 of the rotation preventing lever arm 62 is re-accumulated by the spring force in the S2 direction. As the main locking part 32 of the gripping part 20 approaches the main position, the anti-rotation arm 48 of the claw part 40 slides smoothly from the outlet end 31 of the gripping part 20 to the main locking part 32 through the transition region 39. To do. The positive inclination between the claw portion rotation prevention arm 48 and the gripping portion main locking portion 32 is that the claw portion 40 rotates into the gripping portion 20 only by a slight extension movement of the gripping portion 20 and It is sufficient to open the rotation prevention lever arm 62. Here, the main locking portion 32 for the gripping portion starts to slide down smoothly along the claw portion rotation prevention arm 48. Then, until the anti-rotation lever arm 62 is released and rests under the claw locking portion 54 and the lock unit 10 is returned to the main latch engagement position of FIG. Slide down smoothly along 52.
