In order to make the objects, technical solutions and advantageous technical effects of the present utility model more apparent, the present utility model will be further described in detail with reference to the accompanying drawings and detailed description. It should be understood that the detailed description is intended to illustrate the utility model, and not to limit the utility model.

It is also to be understood that the terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be further understood that the term "and/or" as used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.

In an embodiment of the present utility model, a self-priming lock 100 for a sliding door of an automobile is provided for self-priming locking and unlocking of the sliding door of the automobile, for example, manual door locking or sliding door locking of a vehicle such as an MPV.

As shown in fig. 1-3, an automotive sliding door self-priming lock 100 includes: the self-priming device comprises a first clamping plate 10, a second clamping plate 20, a stop pawl 30, a self-priming assembly 40, an unlocking assembly 50 and a base 60.

The base 60 is intended to be secured to other components of the vehicle. The base 60 includes a seat plate 61, a connection plate 62 vertically connected to the seat plate 61, and a cover 63 provided on a side of the connection plate 62 remote from the seat plate 61. The seat plate 61 and the cover plate 63 can be fixed by rivets, and the assembly process is simple and convenient. Specifically, the seat plate 61, the connection plate 62, and the cover plate 63 together enclose a receiving groove 601. The second clamping plate 20 and the locking claw 30 are both accommodated in the accommodating groove 601, so that the second clamping plate 20 and the locking claw 30 are prevented from falling off from the base 60, and the movement of the second clamping plate 20 and the locking claw 30 in the accommodating groove 601 is not affected.

The first clamping plate 10 is rotatably connected to the bottom of the base 60 and is used for locking or unlocking the sliding door. The shape of the first clamping plate 10 can be designed correspondingly according to the specific requirement of locking. In this embodiment, the first card 10 includes a first locking groove 101, and the first locking groove 101 is used for accommodating a locking component on the sliding door. The seat plate 61 is provided with a second locking groove 611. When the first clamping plate 10 rotates to the position right below the base 60, the side wall of the first locking groove 101 drives the locking component to move into the second locking groove 611, the opening of the second locking groove 611 is closed through the side wall of the first locking groove 101, and the opening of the first locking groove 101 is closed through the side wall of the second locking groove 611, so that the locking component is limited in the second locking groove 611, and the vehicle door is locked; when the first card 10 rotates to form an acute angle with the seat plate 61, the opening of the first locking groove 101 is opened at this time, so that the locking component is separated from the first card 10. Of course, in other embodiments, the first card 10 may also implement the locking function by other locking manners, which is not limited to the above-mentioned exemplary embodiment.

Referring to fig. 6, the second clamping plate 20 is rotatably connected to a side of the base 60 facing away from the first clamping plate 10, and is fixedly connected to the first clamping plate 10 coaxially. Wherein, the first clamping plate 10 and the second clamping plate 20 are connected through a first central shaft 21 provided with a edging structure. That is, the first central shaft 21 is cylindrical, and at least one side is chamfered, and correspondingly, the first clamping plate 10 and the second clamping plate 20 are provided with round holes with chamfered edges, so that the first clamping plate 10 and the second clamping plate 20 can be sleeved on the first central shaft 21 and cannot rotate relatively, and meanwhile, the second clamping plate 20 can drive the first clamping plate 10 to rotate.

Wherein, the edge of the second clamping plate 20 extends outwards to form a first driving arm 22 and a first clamping protrusion 23 respectively. In this embodiment, the second clamping plate 20 is substantially circular, and the first driving arm 22 and the first clamping protrusion 23 extend from the peripheral side of the second clamping plate 20, so as to form a protruding structure correspondingly.

Referring to fig. 6, the locking claw 30 is rotatably connected to the base 60 and disposed near the second clamping plate 20, and the edge extends outwards to form a second driving arm 32 and a second clamping protrusion 33 respectively. Specifically, the locking pawl 30 is attached to the base 60 by a second central shaft 31 having a chamfered edge structure. In the present embodiment, the locking pawl 30 is substantially circular, and the second drive arm 32 and the second catching convex 33 extend from the peripheral side of the locking pawl 30, respectively, so as to form a convex structure accordingly. The second driving arm 32 and the second locking protrusion 33 are respectively arranged at two opposite sides of the locking claw 30.

It should be noted that, the extending heights of the first clamping protrusion 23 and the second clamping protrusion 33 are smaller than the minimum distance between the second clamping plate 20 and the locking claw 30, and the sum of the extending heights of the first clamping protrusion 23 and the second clamping protrusion 33 is larger than the minimum distance between the second clamping plate 20 and the locking claw 30. The extending height of the first engaging protrusion 23 is the distance between the free end of the first engaging protrusion 23 and the circumferential side of the second engaging plate 20, and the extending height of the second engaging protrusion 33 is the distance between the free end of the second engaging protrusion 33 and the circumferential side of the locking claw 30.

Wherein, since the extending heights of the first clamping convex 23 and the second clamping convex 33 are smaller than the minimum distance between the second clamping plate 20 and the locking claw 30, the first clamping convex 23 can pass through the gap between the second clamping plate 20 and the locking claw 30 so as to be abutted with the second clamping convex 33; since the sum of the extending heights of the first clamping protrusion 23 and the second clamping protrusion 33 is larger than the minimum distance between the second clamping plate 20 and the locking claw 30, the second clamping protrusion 33 can abut against the side surface of the first clamping protrusion 23, so that the first clamping protrusion 23 cannot rotate freely, and the locking of the rotation state of the second clamping plate 20 is finally realized. Further, the sides of the first clamping protrusion 23 and the second clamping protrusion 33 may be cambered surfaces, so that the first clamping protrusion 23 is easier to clamp into the locking limiting point of the second clamping protrusion 33.

Further, as shown in fig. 4, a first coil spring 24 is disposed on a side of the second clamping plate 20 facing away from the base 60, and when the first clamping plate 10 is in the unlocked state, the first coil spring 24 drives the first driving arm 22 to rotate from the locking position a and maintain the first driving arm 22 in the unlocking position B, so that the first driving arm 22 abuts against the self-priming assembly 40. That is, the first coil spring 24 has a tendency to disengage the first card protrusion 23 and thus the second card protrusion 33, thereby resetting the second card 20 and maintaining the first card 10 in the unlocked state.

Wherein, a first mounting groove 211 is formed at an end portion of the first central shaft 21 away from the second clamping plate 20. The base 60 is also provided with a fixing groove 64. One end of the first coil spring 24 is fitted into the first fitting groove 211, and the other end is fitted into the fixing groove 64. When the first driving arm 22 rotates from the unlock position B (i.e., the initial position) to the lock position a (i.e., the lock limit of the second click protrusion 33 and the first click protrusion 23), the first coil spring 24 is strained, thereby providing elastic potential energy to the first coil spring 24.

Further, as shown in connection with fig. 4, the side of the pawl 30 facing away from the base 60 is provided with a second coil spring 34. The first coil spring 24 and the second coil spring 34 are both accommodated in the accommodating groove 601. The winding direction of the first coil spring 24 is opposite to the winding direction of the second coil spring 34. That is, the first coil spring 24 has a tendency to disengage the first catching convex 23 from the second catching convex 33, and the second coil spring 34 has a tendency to maintain the second catching convex 33 to lock the first catching convex 23, and since the first card board 10 to which the first coil spring 24 is connected is locked with the sliding door, the resistance received is large, and the resistance received by the holding pawl 30 is small, and therefore the second coil spring 34 holds the holding pawl 30 against the limit point of the holding pawl 30 to maintain the locked state. In addition, when the unlocking action is completed, the locking pawl 30 is reset to the original state by the second coil spring 34. Wherein, the stop pawl 30 can also be provided with a limiting block 56 on the base, and the second coil spring 34 can drive the second driving arm 32 to be reset to the position of the limiting block 56 of the stop pawl 30.

Wherein, a second mounting groove 311 is provided at an end of the second central shaft 31 remote from the locking claw 30. One end of the second coil spring 34 is mounted in the second mounting groove 311, and the other end is mounted in the fixing groove 64.

In an embodiment of the present utility model, as shown in connection with fig. 5, the self-priming assembly 40 is used to drive the first drive arm 22 to rotate from the unlocking position B to the locking position a, so that the second locking protrusion 33 locks the first locking protrusion 23, thereby maintaining the first locking plate 10 in the locked state by the second locking plate 20.

Further, the cover 63 is provided with a relief hole 631 for the first driving arm 22 to pass through at an end far from the seat 61. The shape of the escape hole 631 coincides with the trajectory shape of the first drive arm 22 that rotates from the unlock position B to the lock position a. That is, the escape hole 631 is an arc-shaped hole, and one end thereof away from the locking claw 30 is the unlocking position B, and one end thereof close to the locking claw 30 is the locking position a.

Specifically, the self-priming assembly 40 includes a self-priming fixing plate 41 fixed to the base 60, a self-priming shaft 42 having both ends connected to the base 60 and the self-priming fixing plate 41, a self-priming arm 43 having one side hinged to the self-priming shaft 42, and a self-priming driving part 44 connected to the side of the self-priming arm 43 away from the self-priming shaft 42. That is, the self-priming drive unit 44 is eccentrically disposed with respect to the self-priming shaft 42. In this embodiment, the self-priming driving portion 44 is a cable, and can drive the self-priming arm 43 to rotate under the driving of electric or manual force. The side of the self-priming arm 43 near the cover 63 is provided with a third driving arm 45, and the third driving arm 45 is used for driving the first driving arm 22 to rotate from the unlocking position B to the locking position a under the driving of the self-priming driving part 44, and at this time, since the first clamping protrusion 23 rotates synchronously with the first driving arm 22, the first clamping protrusion 23 is clamped by the second clamping protrusion 33 for locking.

Further, a first torsion spring 46 is sleeved on the self-priming shaft 42, and the first torsion spring 46 is used for driving the third driving arm 45 to reset to the unlocking position B. That is, when the third driving arm 45 drives the first driving arm 22 to move to the locking position a, the self-priming driving portion 44 is released, and the self-priming arm 43 is reset by the first torsion spring 46, so that the third driving arm 45 moves to the unlocking position B, and the next locking operation is performed, and the unlocking of the second card 20 is not hindered.

In the embodiment of the present utility model, as shown in fig. 5, the unlocking component 50 abuts against the second driving arm 32, and is used for driving the locking claw 30 to rotate, so that the second locking protrusion 33 unlocks the first locking protrusion 23, and the first clamping plate 10 unlocks.

Specifically, the unlocking assembly 50 includes an unlocking fixing plate 51 fixed on the base 60, an unlocking shaft 52 provided on the unlocking fixing plate 51, an unlocking arm 53 having one side hinged to the unlocking shaft 52, and an unlocking driving portion 54 connected to the side of the unlocking arm 53 away from the base 60. The unlocking arm 53 abuts the second driving arm 32 on a side close to the unlocking driving portion 54. Wherein, the length between the unlocking driving part 54 and the unlocking shaft 52 is longer than the length of the unlocking arm 53 at the opposite side of the unlocking shaft 52, thereby forming a labor-saving lever structure. The unlocking driving part 54 is a pull rope, and can drive the unlocking arm 53 to rotate under the drive of electric or manual operation so as to drive the locking claw 30 to rotate, so that the second clamping protrusion 33 releases the locking state of the first clamping protrusion 23.

Further, a second torsion spring 55 is sleeved on the unlocking shaft 52. The second torsion spring 55 is used to drive the unlocking arm 53 to return to the original position.

The unlocking arm 53 is in lever connection with the locking claw 30, so that the structure is simple, labor is saved, the transmission chain is single, no redundant moment is generated, the unlocking force of the lock body is small, and the structure is compact. The initial position of the unlocking arm 53 may be limited by the base 60, that is, one end of the unlocking arm 53 away from the unlocking driving portion 54 is simultaneously abutted by the unlocking driving portion 54 and the step structure of the base 60, so that the unlocking arm 53 and the second coil spring 34 limit the locking claw 30 together, and the locking claw 30 is prevented from rotating too much, so that the first locking protrusion 23 is also disengaged from the locking state of the second locking protrusion 33.

The principle of the unlocking process of the utility model is as follows:

The stay rope of the unlocking driving part 54 is driven by the unlocking driving motor or external force, and the stay rope drives the unlocking arm 53 to rotate around the unlocking shaft 52, so that the part, which is close to the unlocking driving part 54, of the unlocking arm 53 with the unlocking shaft 52 as a boundary can pry up the second driving arm 32 of the locking claw 30, and the second driving arm 32 moves along with the unlocking arm 53 at the same time, at the moment, the second clamping plate 20 is separated from the locking of the second clamping protrusion 33 and is reset through the first coil spring 24 (namely, the first driving arm 22 rotates from the locking position A to the unlocking position B); since the first card 10 and the second card 20 are fixedly connected through the first central shaft 21, the first card 10 moves to the unlocking position B along with the second card 20 at the same time, and thus, the unlocking state is maintained. When the unlocking operation is completed, the pawl 30 and the unlocking arm 53 are returned to the original state by the second torsion spring 55.

The principle of the locking process of the utility model is as follows:

the cable of the self-priming driving part 44 pulls the self-priming arm 43 to rotate around the self-priming shaft 42 when driven by electric power; because the third driving arm 45 is abutted against the first driving arm 22, the first driving arm 22 can absorb the thrust of the third driving arm 45, and at the moment, the second clamping plate 20 is driven to rotate from the unlocking position B to the locking position A; because the first clamping plate 10 is fixedly connected with the second clamping plate 20 through the first central shaft 21, the first clamping plate 10 moves along with the second clamping plate 20 at the same time; when the second clamping plate 20 moves, the first clamping protrusion 23 of the second clamping plate 20 pushes the locking claw 30 to do rotary motion through the second clamping protrusion 33, and when the second clamping plate 20 rotates to a preset position, the second clamping protrusion 33 of the locking claw 30 with the second coil spring 34 locks the first clamping plate 10 and the second clamping plate 20. After the second card 20 is locked, the self-priming arm 43 is returned to the initial position by the first torsion spring 46.

It can be understood that the assembly structure of the unlocking fixing plate 51 and the self-priming fixing plate 41 belongs to a '匚' cantilever, and the stress in the middle of the two ends of the structure is fixed, so that the stress is not easy to deform, and the structure is superior to the traditional 'L' -cantilever. After the part is molded, the utility model only relates to a riveting process, the internal stress of the assembly after riveting is small, the unlocking module is optimized, and the unlocking stroke belongs to a labor-saving mechanism. Meanwhile, the utility model has small opening stroke and large overrun stroke, and can be suitable for various unlocking mechanisms.

The utility model also provides an automobile sliding door, comprising the self-priming lock 100 of the automobile sliding door according to any one of the embodiments.

In summary, the self-priming lock 100 for the sliding door of the automobile and the sliding door of the automobile provided by the utility model have the advantages that the self-priming component 40 drives the first driving arm 22 to rotate from the unlocking position B to the locking position A, and the unlocking component 50 drives the locking claw 30 to rotate so as to enable the second clamping protrusion 33 to release the locking state of the first clamping protrusion 23, so that the whole structure is simple, the volume is small, the unlocking force is small, the self-priming sliding door is not easy to deform, the manufacturing process is simple, the structure is reliable, various use conditions can be met, the service life is prolonged, in addition, the assembly structure of the utility model belongs to a '匚' cantilever, the two ends of the structure are fixed, the middle stress is applied, and the structure is superior to the traditional L-shaped cantilever.
