Fig. 1 is a schematic structural view of a side door lock according to one embodiment of the present disclosure.

As shown in fig. 1, the side door lock of the present disclosure may include a lock body 100, a deadbolt assembly 200, a pawl assembly 300, and a power unlock assembly 400.

The lock body 100 may be formed as a housing portion of a side door lock of the present disclosure, which may include, for example, a back plate, a cover, etc., and accordingly, the latch bolt assembly 200 and pawl assembly 300, etc., may be mounted to the back plate and/or cover. The mounting manner of these components may be implemented in a manner known in the art, and this disclosure will not be repeated here.

In some embodiments of the present disclosure, the bolt assembly 200 is rotatably disposed to the lock body 100, and the axis of rotation of the bolt assembly 200 relative to the lock body 100 is a first axis. The tongue component 200 can include at least a locked position and an unlocked position when the tongue component 200 is rotated.

Fig. 2 is a schematic structural view of a tongue component and pawl assembly according to one embodiment of the present disclosure. Fig. 3 is a schematic view of another angled construction of a latch bolt assembly and pawl assembly according to one embodiment of the present disclosure.

As shown in fig. 2 and 3, in one particular embodiment, the bolt assembly 200 may be in a locked position, a semi-locked position, an unlocked position, in other words, the bolt assembly 200 is capable of moving to one of the locked position, the semi-locked position, and the unlocked position when the bolt assembly 200 is actuated to rotate.

In the state shown in fig. 2, the tongue component 200 is in the locked position. In the orientation shown in fig. 2, the latch bolt assembly 200 is capable of being sequentially in a semi-latched position and an unlatched position when rotated counterclockwise. Conversely, when the tongue component 200 is in the unlocked position and rotated clockwise, it can be placed in the semi-locked position and the locked position in sequence. The side door lock is in a locked state when the latch bolt assembly 200 is in the locked position, and in an unlocked state when the latch bolt assembly 200 is in the unlocked position.

In the present disclosure, the counterclockwise movement process (i.e., the unlocking process) of the latch bolt assembly 200 can be accomplished by the elastic force of the return spring. The clockwise movement of the latch bolt assembly 200 (i.e., the locking process) can be accomplished by the pushing force of the striker on the latch bolt assembly 200, or by pulling the latch bolt assembly 200 by an electric locking mechanism, where the side door latch has an electric locking function. The electric locking mechanism can be realized by adopting a scheme in the prior art, and the disclosure is not repeated one by one.

Referring again to fig. 2 and 3, in the present disclosure, the pawl assembly 300 is configured to cooperate with the latch bolt assembly 200 and retain at least the latch bolt assembly 200 in the latched position, and in particular, the pawl assembly 300 of the present disclosure is capable of retaining the latch bolt assembly 200 in both the latched and semi-latched positions.

In one particular embodiment, the pawl assembly 300 includes a first pawl member 310, a second pawl member 320, a sliding pawl member 330, and the like.

The first pawl member 310 is rotatably disposed on the lock body 100. Wherein the first pawl member 310 is a second axis with respect to the rotational axis of the lock body 100, which may be parallel or substantially horizontal to the first axis. In the orientation shown in fig. 1-3, the first and second axes may each be disposed substantially vertically.

The second pawl member 320 is rotatably disposed on the lock body 100. Wherein the second pawl member 320 is a third axis with respect to the rotational axis of the lock body 100, the third axis being disposed parallel or substantially parallel to the second axis, and the third axis being disposed in spaced relation to the second axis.

Thus, the first pawl member 310 is capable of holding the tongue member 200 in the latched position and the second pawl member 320 is capable of holding the tongue member 200 in the semi-latched position.

The second pawl member 320 of the present disclosure is capable of being driven and rotated by the electric unlocking assembly 400 to effect unlocking of the side door lock. Specifically, as the second pawl member 320 is driven to rotate counterclockwise in the direction shown in fig. 2, it can drive the sliding pawl member 330 to act as well as the first pawl member 310 to act and unlock the side door lock.

Specifically, the second pawl member 320 includes a second pawl first slot feature 321 and a second pawl second slot feature 322, and the rotational axis of the first pawl member 310 is slidably disposed within the second pawl first slot feature 321 such that the first pawl member 310 does not interfere with rotation of the second pawl member 320 when the second pawl member 320 is actuated and rotated.

The sliding pawl member 330 includes a sliding pawl first shaft feature 331 that is slidably disposed within the second pawl second slot feature 322 and that, when rotated, the second pawl member 320 is capable of moving the sliding pawl member 330, i.e., causing a sliding motion, whereby the sliding pawl member 330 is capable of moving away from between the first pawl member 310 and the stop member 340 and allowing the first pawl member 310 to rotate counterclockwise, the first pawl member 310 is capable of releasing the latch bolt member 200 and allowing the latch bolt member 200 to move away from the latched position and toward the unlatched position.

Referring again to fig. 3, the sliding pawl member 330 is also capable of driving the first pawl member 310 in rotation, and in particular, the sliding pawl first shaft feature 331 of the sliding pawl member 330 is capable of moving in a tangential direction of a circumference centered on the third axis when the second pawl member 320 is rotated counterclockwise, at which point the sliding pawl member 330 will urge the first pawl member 310 in a counterclockwise direction.

Those skilled in the art will appreciate that the reverse movement of the first pawl member 310, the second pawl member 320 and the sliding pawl member 330 can be achieved by a return spring, and will not be described in detail herein.

In general, the second pawl member 320 is driven to rotate counterclockwise during unlocking of the side door lock, and when the second pawl member 320 is allowed to rotate clockwise and return, the second pawl member 320 can rotate clockwise and return under the return force provided by the return spring.

Fig. 4 is a schematic diagram of a side door lock according to one embodiment of the present disclosure. Fig. 5 is a schematic structural view of an electric lock assembly according to one embodiment of the present disclosure.

The electric unlocking assembly 400 is configured to cooperate with the pawl assembly 300 to enable the pawl assembly 300 to release the latch bolt assembly 200, in other words, the electric unlocking assembly 400 of the present disclosure is configured to drive the second pawl assembly 320 of the pawl assembly 300 to rotate counterclockwise and unlock the side door lock.

Specifically, the electric unlocking assembly 400 of the present disclosure includes a first motor 410 and a worm gear assembly 420 drivingly connected to the first motor 410. Still further, the worm wheel assembly 420 may include a worm wheel part 421 and a safety driving part 422, one end of the safety driving part 422 is rotatably connected to the worm wheel part 421, and the other end (free end) of the safety driving part 422 protrudes to the outside of the worm wheel part 421. Wherein, a worm is provided on the output shaft of the first motor 410, and the worm can be matched with the worm wheel member 421 to rotate the worm wheel member 421 by the rotation of the worm.

As shown in fig. 5, the guard 422 includes a first side surface 422A and a second side surface 422B. In the orientation shown in fig. 5, the first side surface 422A is formed as an upper surface of the fuse driver 422 and the second side surface 422B is formed as a lower surface of the fuse driver 422. More preferably, the first side surface 422A is formed as a concave cambered surface. The second side surface 422B is formed as a convex arc surface so that the fuse driving part 422 is integrally formed as a curved rod-shaped member.

The worm gear part 421 of the worm gear assembly 420 is provided with a first clamp spring 423, the first clamp spring 423 is used for limiting the safety driving piece 422 to an initial position, and when the safety driving piece 422 leaves the initial position, the first clamp spring 423 is used for resetting the safety driving piece 422 to the initial position.

Specifically, the first clamp spring 423 may be a torsion spring that can be sleeved on the rotation shaft of the worm gear member 421, both end portions of the first clamp spring 423 are disposed substantially in parallel, and two columnar portions 422C are provided on the safety driving member 422, and both end portions of the first clamp spring 423 are used to clamp the columnar portions 422C, whereby the first clamp spring 423 can restrict the safety driving member 422 to the initial position.

The worm gear member 421 of the present disclosure rotates about a fourth axis relative to the lock body 100, and the safety drive 422 is a fifth axis relative to the axis of rotation of the lock body 100, the fourth and fifth axes being disposed parallel or substantially parallel. The worm gear member 421 has a tangential plane passing through the fifth axis, which is tangential to a cylindrical surface centered on a fourth axis, which is located on one side of the tangential plane, and the other end of the safety drive 422 is located on the other side of the tangential plane. At this time, an included angle (an included angle is formed between the tangent plane and the connecting line between one end and the other end of the safety driving member 422) is formed between the safety driving member 422 and the tangent plane, and the angle value of the included angle can be changed along with the rotation of the safety driving member 422.

In a preferred embodiment, the diameter of the columnar portion 422C may be the same as the distance between both end portions of the first clamp spring 423, and at this time, the distance between both end portions of the first clamp spring 423 is the minimum. When the safety driving member 422 rotates, the distance between the two ends of the first clamp spring 423 increases with the change of the angle value of the included angle, and at this time, the two ends of the first clamp spring 423 tend to shrink inwards, so that the safety driving member 422 has a tendency to return to the initial position.

Fig. 6 is a schematic view of another angle configuration of an electric lock assembly according to one embodiment of the present disclosure. Fig. 7 is a schematic structural view of a part of the structure of a side door lock according to an embodiment of the present disclosure.

Specifically, as shown in fig. 6 and 7, the lever member 430 includes a lever first arm feature 431, a lever second arm feature 432, a lever third arm feature 433, a lever slot feature 434, and the like. The lever first arm feature 431, lever second arm feature 432, and lever third arm feature 433 are each formed as an arm of the lever member 430. Wherein the lever first arm feature 431 is capable of cooperating with the cam structure 421A on the worm gear member 421 such that when the worm gear member 421 is rotated, it is capable of pushing the lever member 430 to rotate.

Specifically, in the direction shown in fig. 6, when the worm wheel part 421 rotates clockwise, it can push the operation lever part 430 to rotate counterclockwise. Of course, in the direction shown in fig. 5, when the worm wheel part 421 rotates counterclockwise, it can push the lever part 430 to rotate clockwise. Thus, the lever second arm feature 432 of the lever member 430 is able to urge the second pawl member 320 to rotate. At this time, the second pawl member 320 rotates counterclockwise in the direction shown in fig. 2 and 3, thereby effecting unlocking of the side door lock.

The specific structure of the safety lever 600 and the mating relationship with the worm gear assembly 420 will be described below in connection with fig. 8-13.

As shown in fig. 8 to 13, the safety lever 600 of the present disclosure includes a first engagement portion 630 and a second engagement portion 640, and the safety driver 422 is selectively engaged with the first engagement portion 630 or the second engagement portion 640 to push the safety lever 600 to rotate in different rotational directions.

Wherein, when the safety lever 600 is located at the first position, the safety driving piece 422 can be engaged with the first engaging portion 630 to drive the safety lever 600 from the first position to the second position.

Specifically, the first fitting portion 630 includes a first groove formed at a side portion of the safety lever 600, and an opening of the first groove faces the worm wheel assembly 420.

The first recess includes a first upper side wall 631 and a first lower side wall 632. When the safety lever 600 is in the first position, the other end of the safety drive 422 contacts the first upper side wall 631 (as shown in fig. 9). At this time, since the safety lever 600 is located at the first position, it cannot continue to rotate further counterclockwise, so that the safety driving member 422 will slide along the inner sidewall of the first groove and cooperate with the first lower sidewall 632 (as shown in fig. 10) with further rotation of the worm gear 421.

The safety lever 600 is formed with a boss 650, and the boss 650 is used to form the first upper sidewall 631 of the first recess. In the state shown in fig. 10, when the other end of the safety driving piece 422 is engaged with the first lower sidewall 632, the protrusion 650 contacts the first side surface of the safety driving piece 422 and makes the included angle of the safety driving piece 422 become larger to push the safety lever 600 to rotate clockwise (in the direction shown in fig. 8 to 10) and move from the first position to the second position.

The state shown in fig. 11 is where the safety lever 600 is in the second position. As shown in fig. 11 to 13, when the safety lever 600 is located at the second position, the safety driving member 422 can be engaged with the second engaging portion 640 to drive the safety lever 600 from the second position to the first position.

Specifically, the second fitting part 640 includes a second groove formed at a side of the safety lever 600, and an opening of the second groove faces the worm wheel assembly 420.

In other words, the second groove of the present disclosure is located above the first groove, and the portion between the first groove and the second groove, that is, the above-described protruding portion 650.

The second recess includes a second upper side wall 641 and a second lower side wall 642, and when the safety lever 600 is in the second position, the other end of the safety drive 422 contacts the second upper side wall 641 to push the safety lever 600 to rotate counterclockwise and move from the second position to the first position. That is, when the safety lever 600 is in the second position, the other end of the safety drive 422 is able to pass over the first recess and not engage the first recess, but engage the second recess directly.

Wherein the boss 650 is used to form the second lower side wall 642 of the second recess, and the boss 650 contacts the second side surface 422B of the fuse driver 422 when the other end of the fuse driver 422 is mated with the second upper side wall 641.

In general, when the safety lever 600 is in the first position, the upper end of the safety lever 600 is away from the worm wheel assembly 420, and the lower end of the safety lever 600 is close to the worm wheel assembly 420, and when the safety lever 600 is in the second position, the upper end of the safety lever 600 is close to the worm wheel assembly 420, and the lower end of the safety lever 600 is away from the worm wheel assembly 420. In this manner, the safety lever 600 of the present disclosure can be facilitated to cooperate with the safety drive 422.

Based on the above structure, when the side door lock of the present disclosure is in operation, when the first motor 410 rotates in the first direction, the worm gear 421 of the electric unlocking assembly 400 will rotate counterclockwise (in the direction shown in fig. 5), and the pawl assembly 300 is driven to act by the operating lever 430, so as to unlock the side door lock. When the first motor 410 rotates along the second direction, the worm gear 421 of the electric unlocking assembly 400 will rotate clockwise (in the direction shown in fig. 5), and at this time, the safety driving member 422 will drive the safety lever 600 to act, so as to switch between the up-safety state and the down-safety state of the safety lever 600. Meanwhile, when the safety lever 600 is in the first position, the safety lever 600 is in the unbuckled state, and at this time, the side door lock can be opened by the outside-open lever 510. In addition, when the safety lever 600 is in the second position, the safety lever 600 is in the upper safety state, and the side door lock cannot be opened by the outside-open lever 510.

Based on the above structure, the side door lock in the present disclosure can be unlocked directly through the electric unlocking assembly, and the electric unlocking assembly can also switch the state of the safety pull rod 600. Meanwhile, the electric unlocking component realizes the two functions in forward and reverse rotation, and accordingly, the upper insurance or the unsafe state of the insurance pull rod 600 is not influenced when the side door lock is unlocked in an electric mode.

Fig. 14 is a schematic structural view of a lock cylinder lever according to one embodiment of the present disclosure.

As shown in fig. 4 and 14, the side door lock of the present disclosure may further include a key cylinder draw bar 101, whereby the side door lock can be mounted to a corresponding side door of a driving seat, and accordingly, the side door lock of the present disclosure can be opened and closed by a key. Specifically, when the lock cylinder 102 is rotated, it can drive the lock cylinder lever 101 to move, and the safety lever 600 is driven by the lock cylinder lever 101, and the safety lever 600 is located at the first position or the second position. Further, when the side door lock needs to be opened, the safety pull rod 600 can be driven to the first position, and then the unlocking of the side door lock is achieved through the first manual unlocking assembly 500, and when the side door lock needs to be closed, the safety pull rod 600 can be driven to the second position, so that the unlocking of the side door lock cannot be achieved even though the first manual unlocking assembly 500 is pulled.

Referring again to fig. 6, the side door lock of the present disclosure may also have an electric child protection function. Specifically, the side door lock of the present disclosure further includes a child safety assembly 800, when the child safety assembly 800 is in the upper safety state, the unlocking of the side door lock cannot be achieved through the second manual unlocking assembly 900, and when the child safety assembly 800 is in the lower safety state, the unlocking of the side door lock can be achieved through the second manual unlocking assembly 900.

Specifically, the second manual unlocking assembly 900 of the present disclosure may include an inside open lever rotatably disposed to the lock body 100 and having the same axis of rotation as the lever member 430, and selectively engageable with the lever third arm feature 433 of the lever member 430 to selectively drive rotation of the lever member 430.

Specifically, the child-resistant assembly 800 may include a second motor 810, the second motor 810 being provided to the lock body, and an output shaft of the second motor 810 being provided with a worm capable of meshing with the child-resistant worm wheel 820 and rotating the child-resistant worm wheel 820 by rotation of the worm.

Thus, in the direction shown in fig. 7, when the child-resistant link 830 is driven and moves rightward (e.g., to the right end of the elongated slot), the inside open lever can be in driving connection with the lever member 430, specifically, when the inside open lever is driven and rotates clockwise, the lever member 430 can be driven to rotate clockwise, and unlocking of the side door lock can be achieved. On the other hand, when the child protection link 830 is driven and moved leftward (e.g., to the left end of the elongated slot), the clockwise rotation of the inside open lever does not drive the operation lever part 430 to rotate clockwise, and thus the side door lock cannot be opened by the inside open lever, thereby realizing the child protection function.

In another embodiment, the child protection link 830 of the present disclosure may be manually operated and moved, thereby enabling the child protection function of the present disclosure to be manually turned on or off.

In a preferred embodiment, the side door lock may further comprise a first position detecting means, which may be a travel switch, and detect the position of the child-resistant worm gear 820 through the travel switch. Wherein the travel switch is capable of being actuated and closed when the child-resistant assembly is in the arming state, whereby the controller may inhibit unlocking movement of the first motor based on the closed state of the travel switch. I.e., unlocking of the side door lock cannot be accomplished by the electric unlocking assembly 400 at this time. That is, the overall vehicle controller may shield or turn on the electric unlocking function depending on the state of the child protection assembly.

In a further preferred embodiment, the side door lock may further comprise a second position detecting means, which may be a travel switch, and the position of the safety lever is detected by the travel switch. Wherein the travel switch can be driven and closed when the safety lever is in the upper safety state, whereby the controller can prohibit the unlocking movement of the first motor according to the closed state of the travel switch. I.e., unlocking of the side door lock cannot be accomplished by the electric unlocking assembly 400 at this time. That is, the whole vehicle controller may shield or turn on the electric unlocking function according to the state of the safety lever.

In whole, when the side door of this disclosure is in use, electronic unblock function and manual unblock function can not influence each other, under the outage state after whole car collision, also can be safely unblock through interior open pull rod, have improved the security performance of whole car.
