An automobile door lock 1 according to an embodiment of the present invention is described below with reference to the drawings.

As shown in fig. 1 to 6, an automobile door lock 1 according to an embodiment of the present invention includes a lock case 100, a latch tongue 200, a latch arm 300, a driving unit 400, and a fork 500.

The latch bolt 200 is rotatably installed at the lock case 100 between a fully opened position and a fully closed position, and the latch bolt 200 rotates between the fully closed position and the fully opened position, and is engaged with the lock case 100 to lock and unlock the door of the vehicle. The lock arm 300 is rotatably mounted to the lock case 100 between a locked position, in which the lock arm 300 holds the latch tongue 200 at the fully closed position, and an unlocked position, in which the lock arm 300 allows the latch tongue 200 to rotate to the fully open position. The drive unit 400 is mounted to the lock housing 100 and drives the lock arm 300 to rotate between the locked and unlocked positions. The fork 500 is rotatably installed on the lock case 100, the lock arm 300 is stopped by the fork 500 after rotating to the unlock position, and the latch 200 jacks up the fork 500 to release the stop of the lock arm 300 after rotating to the full open position.

For example, when the door of the automobile needs to be opened, the unlocking signal is output through a key or an external switch of the tailgate, the driving unit 400 drives the locking arm 300 to rotate to the unlocking position, at this time, the locking arm 300 is stopped by the shift fork 500 and cannot rotate back to the locking position (as shown in fig. 5), until the lock tongue 200 jacks up the shift fork 500 after rotating to the fully open position, the stopping of the locking arm 300 is released, and the locking arm 300 can rotate back to the locking position (as shown in fig. 6).

According to the automobile door lock 1 provided by the embodiment of the utility model, by arranging the shifting fork 500, the locking arm 300 can be stopped at the unlocking position by using the shifting fork 500, and the locking arm 300 is prevented from rotating back to the locking position again before the bolt 200 rotates to the full-open position, so that a snow load function is realized, repeated locking can be avoided, the situation that a user needs to unlock for many times is eliminated, and the use is more convenient.

In addition, according to the automobile door lock 1 provided by the embodiment of the utility model, the snow load function is realized through the shifting fork 500, the shifting fork 500 is utilized to establish the motion relationship between the locking arm 300 and the lock tongue 200, compared with a mode that the locking arm and the lock tongue are directly matched in the technology, the mold opening cost of the locking arm 300 and the lock tongue 200 is lower, and the shifting fork 500 is used as a modularized component and can be flexibly disassembled and assembled, so that the automobile door lock 1 can be freely switched between two states of having the snow load function and not having the snow load function, for example, for some vehicles without the snow load function, the shifting fork 500 can be independently disassembled and assembled to realize the basic function of the door lock, and the application of the automobile door lock 1 is more flexible.

Therefore, the automobile door lock 1 provided by the embodiment of the utility model has the advantages of flexible application, capability of giving consideration to snow-load function and cost and the like.

In some embodiments of the present invention, as shown in fig. 3, the car door lock 1 further includes a fork return elastic member 600, and the fork return elastic member 600 is connected to the fork 500 and the lock case 100, respectively.

For example, the fork return spring 600 may be a torsion spring. When the locking arm 300 rotates from the locking position to the unlocking position, the shifting fork 500 is jacked up, and the shifting fork 500 overcomes the elasticity of the shifting fork return elastic member 600 to rotate. When the locking arm 300 is in the unlocking position, the shift fork 500 is reset by the elastic force of the fork reset elastic member 600 and stops against the locking arm 300. When the latch bolt 200 rotates to the fully open position, the shift fork 500 is jacked up again, the shift fork 500 overcomes the elastic force of the shift fork reset elastic member 600 to rotate, the stopping of the locking arm 300 is released, the locking arm 300 rotates to the locking position, and after the latch bolt 200 rotates back to the fully closed position again, the shift fork 500 resets under the elastic force of the shift fork reset elastic member 600.

Further, as shown in fig. 3 to 6, the locking arm 300 is provided with a first boss 310, a side wall of the first boss 310 is provided with a blocking rib 311, and the shift fork 500 is configured with a first recess 510 recessed in a direction away from the first boss 310.

When the locking arm 300 is located at the locking position, the cylindrical surface of the first protrusion 310 is engaged with the first recess 510, and the first recess 510 provides a receiving space for the first protrusion 310 to avoid interference. During the rotation of the locking arm 300 to the unlocking position, the first boss 310 jacks up the fork 500. Wherein the cylinder of first concave part 510 and first projection 310 is smooth arc surface, and the cylinder of first projection 310 is the convex surface, and first concave part 510 is the concave surface, and first projection 310 has higher laminating nature with first concave part 510 to keep smooth transition, reduced the resistance of first projection 310 and the relative slip process of first concave part 510, make the motion trail of locking arm 300 and shift fork 500 more reasonable.

After the locking arm 300 rotates to the unlocking position, the shifting fork 500 is stopped at the connection position of the first protruding column 310 and the blocking rib 311 under the elastic force of the shifting fork resetting elastic piece 600, so that the locking arm 300 is kept at the unlocking position, and the locking arm 300 is prevented from rotating back to the locking position. The shape formed at the joint of the first convex column 310 and the blocking rib 311 is matched with the shape of the end of the shifting fork 500, so that the shifting fork 500 is stopped at the joint of the first convex column 310 and the blocking rib 311, and the shifting fork 500 has high stability, so that the locking arm 300 is kept at the unlocking position, and the snow-load function is realized.

Alternatively, the lock case 100 may be configured with a guide groove 150, an end of the first boss 310 far away from the locking arm 300 may be fitted in the guide groove 150, and the first boss 310 may slide along the guide groove 150 during the rotation of the locking arm 300, so as to define a movement path of the first boss 310 and the locking arm 300, and improve the movement stability of the first boss 310 and the locking arm 300.

Further, as shown in fig. 2 and 4, one end of the fork 500 is rotatably mounted to the lock case 100, a fork return elastic member 600 is located at the one end of the fork 500, and a first recess 510 is provided adjacent to the other end of the fork 500. During the rotation of the locking arm 300 to the unlocking position, the first boss 310 jacks up the other end of the shift fork 500. After the locking arm 300 rotates to the unlocking position, the other end of the shifting fork 500 is stopped at the connection position of the first protruding column 310 and the blocking rib 311. Thus, the movement range of the free end of the fork 500 is fully utilized, and the locking arm 300 can be better stopped and released.

In some embodiments of the present invention, as shown in fig. 3 to 6, the locking bolt 200 is provided with the second boss 210, the fork 500 is configured with a protrusion 520 protruding toward the second boss 210 and a second recess 530 recessed away from the second boss 210, and the protrusion 520 may be located between the first recess 510 and the second recess 530.

When the latch tongue 200 is located at the fully closed position, the second protrusion 210 is engaged with the second recess 530. When the latch 200 is at the fully open position, the second protrusion 210 pushes up the fork 500 by pushing the protrusion 520. The cylindrical surface of the second convex column 210, the convex part 520 and the second concave part 530 are smooth arc surfaces, so that smooth transition is maintained, the resistance of the second convex column 210 for jacking the shifting fork 500 is reduced, and the movement tracks of the lock tongue 200 and the shifting fork 500 are more reasonable.

Therefore, the first concave part 510, the convex part 520 and the second concave part 530 are sequentially formed from the other end to the one end of the shift fork 500 along the length direction, so that not only can the stability of the shift fork 500 at the initial position be ensured, but also the shift fork 500 can be jacked up by the locking arm 300 and the locking tongue 200.

In some embodiments of the present invention, as shown in fig. 3-6, the latch arm 300 is configured with a latch tooth 320 and the latch tongue 200 is configured with a latch slot 220.

When the latch arm 300 is located at the latch position and the latch tongue 200 is located at the fully closed position, the latch tooth 320 is engaged with the latch groove 220. At this time, the locking tooth 320 cooperates with the locking groove 220 to keep the latch tongue 200 at the fully closed position, thereby locking the vehicle door. When the locking arm 300 is located at the unlocking position and the locking tongue 200 is located at the fully closed position, the locking tooth 320 is separated from the locking groove 220, and the locking tongue 200 can rotate to the fully open position, so that the vehicle door can be unlocked.

For example, the locking tooth 320 is formed on the side of the locking arm 300 facing the locking tongue 200 and protrudes, the locking groove 220 is formed on the side of the locking tongue 200 facing the locking arm 300 and is recessed, and the locking tongue 200 is fixed by the locking tooth 320 engaging with the locking groove 220. The latch tongue 200 is unlocked by the latch arm 300 being disengaged from the latch groove 220, allowing the latch tongue 200 to be rotated toward the fully open position.

In some embodiments of the present invention, as shown in fig. 2 and 3, the driving unit 400 includes a motor 410, a worm gear 430, and a worm gear return elastic member 440.
