[0025] Referring to Fig. 1 and Fig. 2, the present embodiment provides an automobile door lock applied to an automobile door of a vehicle, wherein the vehicle includes a car or recreation vehicle, and the automobile door lock is configured to lock the automobile door and plays a role in protecting safety so as to guarantee the safety of life and property.
[0026] The automobile door lock provided in the present embodiment includes an outward-opening handle assembly 300, an inward-opening handle assembly 200, a central structure assembly 100, and at least one lock body assembly 400, wherein the outward-opening handle assembly 300, the inward-opening handle assembly 200 and the lock body assembly 400 are all connected to the central structure assembly 100; the outward-opening handle assembly 300 controls the lock body assembly 400 via the central structure assembly 100 to perform an unlocking action; the inward-opening handle assembly 200 controls the lock body assembly 400 via the central structure assembly 100 to perform an unlocking action, and the outward-opening handle assembly 300 and the inward-opening handle assembly 200 do not interfere with each other.
[0027] Referring to Fig. 3, Fig. 4 and Fig. 5, the above central structure assembly 100 is provided inside the automobile door and includes a transmission structure 110 and a safety structure 120.
[0028] The transmission structure 110 includes a bottom board 111, an outward-opening linkage board 112, an inward-opening linkage board 113 and an opening linkage board 114 that are rotatably provided on the bottom board 111. The outward-opening linkage board 112, the inward-opening linkage board 113 and the opening linkage board 114 are provided along a normal direction of the bottom board 111 in sequence, that is, the inward-opening linkage board 113 is located between the outward-opening linkage board 112 and the opening linkage board 114, and the outward-opening linkage board 112 is closer to the bottom board 111 than the opening linkage board 114. The outward-opening linkage board 112 is configured to be linked with the opening linkage board 114 to rotate, and the inward-opening linkage board 113 is configured to be linked with the outward-opening linkage board 112 to rotate.
[0029] In the present embodiment, the outward-opening linkage board 112 is connected to the outward-opening handle assembly 300, that is, the outward-opening handle assembly 300 controls the outward-opening linkage board 112 to rotate; the inward-opening linkage board 113 is connected to the inward-opening handle assembly 200, that is, the inward-opening handle assembly 200 controls the inward-opening linkage board 113 to rotate; and each lock body assembly 400 is connected to the opening linkage board 114, that is, the opening linkage board 114 can control the lock body assembly 400 to perform an unlocking action.
[0030] Further preferably, the bottom board 111 is provided with a central control rotating shaft 1110, wherein the outward-opening linkage board 112, the inward-opening linkage board 113 and the opening linkage board 114 are all provided on the central control rotating shaft 1110, that is, the outward-opening linkage board 112, the inward-opening linkage board 113 and the opening linkage board 114 can all rotate around an axis of the central control rotating shaft 1110.
[0031] The safety structure 120 includes a safety swing arm mechanism 121, a safety actuator 122, and a safety linkage board 123, wherein the safety swing arm mechanism 121 is provided on the opening linkage board 114, the safety swing arm 122 and the safety linkage board 123 are both provided on the bottom board 111, and the safety actuator 122 drives the safety linkage board 123 to rotate so as to drive the safety swing arm mechanism 121 to switch between the first position and the second position.
[0032] In the present embodiment, it is defined that when the safety swing arm mechanism 121 is located at the first position, a safety is unlocked, and when the safety swing arm mechanism 121 is located at the second position, the safety arrangement is locked.
[0033] In an initial state, the safety swing arm mechanism 121 is located at the first position, that is, the safety arrangement is unlocked, the opening linkage board 114 and the outward-opening linkage board 112 are in linkage cooperation, that is, when the outward-opening linkage board 112 rotates, the opening linkage board 114 is driven to rotate together, and then the opening linkage board 114 drives the lock body assembly 400 to perform an unlocking action.
[0034] When the safety linkage board 123 drives the safety swing arm mechanism 121 to switch to the second position, that is, the safety arrangement is locked, the linkage cooperation of the opening linkage board 114 and the outward-opening linkage board 112 is released, and the inward-opening linkage board 113 abuts against the safety linkage board 123, that is, when the outward-opening linkage board 112 rotates, the opening linkage board 114 is not driven to rotate together, so that the opening linkage board 114 does not drive the lock body assembly 400 to perform an unlocking action. However, in this state, when the inward-opening linkage board 113 rotates, the safety linkage board 123 can be pushed to rotate so as to release the restriction of the safety linkage board 123 on the safety swing arm mechanism 121, so that the safety swing arm mechanism 121 automatically switches back to the first position from the second position to unlock the safety arrangement. That is, when the safety arrangement is locked, driving the inward-opening linkage board 113 to rotate for the first time cannot drive the opening linkage board 114 to rotate together, and only when the inward-opening linkage board 113 is driven to rotate again, the inward-opening linkage board 113 will be linked with the opening linkage board 114 to rotate together so as to drive the lock body assembly 400 to perform an unlocking action.
[0035] In the present embodiment, when the safety arrangement is locked, the inward-opening linkage board 113 and the outward-opening linkage 112 are in ratchet cooperation because the linkage cooperation of the opening linkage board 114 and the outward-opening linkage board 112 is released. At this moment, when the outward-opening linkage board 112 rotates, the inward-opening board 113 remains stationary; and when the inward-opening linkage board 113 rotates, the outward-opening linkage board 112 is driven to rotate synchronously so as to unlock the safety arrangement at the same time. When the safety arrangement is unlocked, the linkage cooperation of the opening linkage board 114 and the outward-opening linkage board 112 is restored, the inward-opening linkage board 113 is driven to rotate again, and the inward-opening linkage board 113 drives the outward-opening linkage board 112 to rotate synchronously, so that the opening linkage board 114 is driven to rotate to drive the lock body assembly 400 to perform an unlocking action.
[0036] The safety swing arm mechanism 121 includes a swing arm body 1211 and a linkage shaft 1212, wherein the swing arm body 1211 is rotatably provided on the opening linkage board 114 via a swing arm rotating shaft 1210, the linkage shaft 1212 is provided at one end, away from the swing arm rotating shaft 1210, of the swing arm body 1211, and the linkage shaft 1212 extends toward the bottom board 111.
[0037] Further preferably, the opening linkage board 114 is provided with a first long kidney-shaped hole 1140 for allowing the linkage shaft 1212 to pass through, wherein the first long kidney-shaped 1140 is in an arc shape that is adaptive to a trajectory of the linkage shaft 1212 moving with the swing arm body 1211. Moreover, the first long kidney-shaped hole 1140 includes a first end part and a second end part that are distributed along a length direction, wherein the first end part is close to a rotation center of the opening linkage board 114, and the second end part is far away from the rotation center of the opening linkage board 114.
[0038] The outward-opening linkage board 112 is provided with an L-shaped linkage slot 1120 for accommodating the linkage shaft 1212, wherein the L-shaped linkage slot 1120 has a first slot section 1120a and a second slot section 1120b that are communicated, that is, the first slot section 1120a and the second slot section 1120b are connected to form an L shape, further, the first slot section 1120a extends toward a rotation center of the outward-opening linkage board 112, and the second slot section 1120b extends along a circumferential direction of the outward-opening linkage board 112.
[0039] The operating principles of the safety swing arm mechanism 121, the outward-opening linkage board 112, and the opening linkage board 114 are as follows:
in the initial state, the safety swing arm mechanism 121 is located at the first position, in this case, the safety arrangement is unlocked; and the linkage shaft 1212 is located at the first end part and the first slot section 1120a, so that the linkage cooperation of the outward-opening linkage board 112 and the opening linkage board 114 is realized. It can be understood that because the linkage shaft 1212 is located at the first end part of the first long kidney-shaped hole 1140 and the first slot section 1120a of the L-shaped linkage slot 1120, when the outward-opening linkage board 112 rotates, the linkage shaft 1212 abuts against the outward-opening linkage board 112 and the opening linkage board 114 at the same time, and when the outward-opening linkage board 112 rotates, the opening linkage 114 is driven to rotate together.
[0040] When the safety swing arm mechanism 121 switches to the second position, in this case, the safety arrangement is locked; and the linkage shaft 1212 is located at the second end part of the first long kidney-shaped hole 1140 and the second slot section 1120b of the L-shaped linkage slot 1120, so that the linkage cooperation of the outward-opening linkage board 112 and the opening linkage board 114 is released. It can be understood that because the linkage shaft 1212 is located at the second end part and the second slot section 1120b, when the outward-opening linkage board 112 rotates, the outward-opening linkage board 112 does not contact the linkage shaft 1212, and when the outward-opening linkage board 112 rotates, the opening linkage board 114 is not driven to rotate.
[0041] The safety swing arm mechanism 121 further includes a safety reset spring, wherein the safety reset spring is sheathed on the swing arm rotating shaft 1210, the safety reset spring and the swing arm body 1211 as well as the opening linkage board 114 are in abutting cooperation, the safety reset spring is configured to keep the safety swing arm mechanism 121 at the first position, that is, to keep the linkage shaft 1212 at the first end part and in the first slot section 1120a. Therefore, it can be understood that by the safety reset spring, the safety swing arm mechanism 121 always has a tendency to move from the second position to the first position. Optionally, the safety reset spring is a torsional spring.
[0042] Rotation directions of the safety linkage board 123 includes a first rotation direction and a second rotation direction, wherein the first rotation direction is opposite to the second rotation direction, as shown in Fig. 4, the first rotation direction of the safety linkage board 123 is anticlockwise, and the second rotation direction is clockwise.
[0043] Further preferably, the safety linkage board 123 is provided with a U-shaped notch 1230 adaptive to the linkage shaft 1212, wherein the U-shaped notch 1230 has a side wall surface.
[0044] When the safety linkage board 123 is located between the outward-opening linkage board 112 and the inward-opening linkage board 113, an opening of the U-shaped notch 1230 faces the linkage shaft 1212 in the safety swing arm mechanism 121.
[0045] When the safety is locked, the side wall surface of the U-shaped notch 1230 abuts against the linkage shaft 1212 in the safety swing arm mechanism 121, at this moment, when the safety linkage board 123 is driven to rotate in the first rotation direction, the side wall surface of the U-shaped notch 1230 does not abut against the linkage shaft 1212, the safety swing arm mechanism 121 moves toward the first position under the action of the safety reset spring, the linkage shaft 1212 moves toward the first end part of the first long kidney-shaped hole 1140, and at the same time, the linkage shaft 1212 enters the first slot section 1120a of the L-shaped linkage slot 1120 so as to unlock the safety arrangement.
[0046] When the safety arrangement is unlocked and the safety linkage board 123 is driven to rotate in the second rotation direction again, the side wall surface of the U-shaped notch 1230 pushes against the linkage shaft 1212 of the safety swing arm mechanism 121 to move toward the second position so as to overcome an elastic force of the safety reset spring, at this moment, the side wall surface of the U-shaped notch 1230 abuts against the linkage shaft 1212 so as to push the linkage shaft 1212 to move toward the second end part of the first long kidney-shaped hole 1140, and at the same time, the linkage shaft 1212 enters the second slot section 1120b of the L-shaped linkage slot 1120 so as to lock the safety arrangement.
[0047] It can be seen from the above that through the switching of the safety linkage board 123 between the first rotation direction and the second rotation direction, the switching of the safety swing arm mechanism 121 between the first position and the second position is realized, that is, the switching of the safety arrangement between unlocking and locking is realized.
[0048] In the present embodiment, when the safety arrangement is locked, because the inward-opening linkage board 113 abuts against the safety linkage board 123, the inward-opening linkage board 113 can push against the safety linkage board 123 by driving the inward-opening linkage board 113 to rotate so as to unlock the safety arrangement. When the inward-opening linkage board 113 is driven to rotate again, the inward-opening linkage board 113 drives the opening linkage aboard 114 via the outward-opening linkage board 112 to rotate together so as to drive the lock body assembly 400 to perform an unlocking action.
[0049] Specifically, the inward-opening linkage board 113 further includes a rotating body part 1130 and a toggling arm 1131 connected to the rotating body part 1130, wherein the rotating body part 1130 and the bottom board 111 are in rotations cooperation, that is, the rotating body part 1130 is mounted on the central control rotating shaft 1110.

[0082] With reference to the drawings, various functions of the automobile door lock provided in the present embodiment are realized as follows:
- (I) safety locking:
1.1) the safety arrangement is locked by the safety actuator 122: the remote key assembly or the PEPS button 330 on the outward-opening hand shank 320 is pushed, and the safety actuator 122 is started up, so that the safety arrangement linkage board 123 is driven to rotate in the second rotation direction, the side wall surface of the U-shaped notch 1230 pushes against the linkage shaft 1212 of the safety swing arm mechanism 121 to move toward the second position so as to overcome the elastic force of the safety reset spring, at this moment, the side wall surface of the U-shaped notch 1230 abuts against the linkage shaft 1212 so as to push the linkage shaft 1212 to move toward the second end part of the first long kidney-shaped hole 1140, and at the same time, the linkage shaft 1212 enters the second slot section 1120b of the L-shaped linkage slot 1120 so as to lock the safety arrangement.
1.2) the safety arrangement is locked by the safety button 230: the safety button 230 located at the inward-opening handle base 210 is pushed to drive the safety linkage board 123 via the second stay wire component 231 to rotate in the second rotation direction so as to lock the safety arrangement.
1.3) the safety arrangement is locked by the automobile key: the automobile key is inserted into the key hole of the lock cylinder 340 and twisted to drive the safety linkage board 123 via the transmission pin 350 to rotate in the second rotation direction so as to lock the safety arrangement.
- (II) safety unlocking:
2.1) the safety arrangement is unlocked by the safety actuator 122: the remote key assembly or the PEPS button 330 on the outward-opening hand shank 320 is pushed, and the safety actuator 122 is shut down, so that the safety linkage board 123 is driven to rotate back to the first rotation direction, the side wall surface of the U-shaped notch 1230 does not abut against the linkage shaft 1212, the safety swing arm mechanism 121 moves toward the first position under the action of the safety reset spring, the linkage shaft 1212 moves toward the first end part of the first long kidney-shaped hole 1140, and at the same time, the linkage shaft 1212 enters the first slot section 1120a of the L-shaped linkage slot 1120 so as to unlock the safety arrangement.
2.2) the safety arrangement is unlocked by the safety button 230: the safety button 230 is pushed reversely to drive the safety linkage board 123 via the second stay wire component 231 to rotate back to the first rotation direction, and under the action of the reset spring, the safety swing arm mechanism 121 returns to the first position so as to unlock the safety arrangement.
2.3) the safety arrangement is unlocked by the automobile key: the automobile key is inserted into the key hole of the lock cylinder 340 and twisted reversely to drive the safety linkage board 123 via the transmission pin 350 to rotate back to the first rotation position so as to unlock the safety arrangement.
- (III) controlling the lock body assembly 400 to perform an unlocking action by pulling
the outward-opening hand shank 320:
3.1) in a safety locking state, pulling the outward-opening hand shank 320 cannot control the lock body assembly 400 to perform an unlocking action: specifically, the 320 is pulled to drive the outward-opening linkage board 112 to rotate in an unlocking direction through the linkage relationship between the outward-opening switching mechanism 360 and the pull rod 321. At this moment, because the linkage shaft 1212 is located at the second slot section 1120b of the L-shaped linkage slot 1120, the outward-opening linkage board 112 does not contact the linkage shaft 1212, so that rotating the outward-opening linkage board 112 cannot drive the opening linkage 114 to rotate, and thus the lock body assembly 400 cannot be controlled to perform the unlocking action.
3.2) in a safety unlocking state, pulling the outward-opening hand shank 320 drives the outward-opening linkage board 112 to rotate in the unlocking direction through the linkage relationship between the outward-opening switching mechanism 360 and the pull rod 321. At this moment, because the linkage shaft 1212 is located at the first slot section 1120a of the L-shaped linkage slot 1120, when the outward-opening linkage board 112 rotates, the linkage shaft 1212 will abut against the outward-opening linkage board 112 and the opening linkage board 114 at the same time, and when the outward-opening linkage board 112 rotate, the opening linkage board 114 is driven to rotate together. When the opening linkage board 114 rotates, the switching swing arm piece 432 is driven via the third stay wire component 114a to rotate, the switching swing arm piece 432 drives the stop hook 423 via the lock body opening connection rod 433 to rotate, the stop hook 423 drives the rotating tongue piece 422 to rotate so as to release the cooperation between the rotating tongue piece 422 and the U-shaped lock latch 500, thereby completing the unlocking action.
- (IV) controlling the lock body assembly 400 to perform an unlocking action by pulling
the inward-opening hand shank 220:
4.1) in a safety unlocking and child lock unlocking state, the automobile door is opened by the inward-opening hand shank 220: the inward-opening hand shank 220 is pulled to drive the inward-opening linkage board 113 via the first stay wire component 221 to rotate in the unlocking direction. At this moment, the inward-opening linkage board 113 drives the outward-opening linkage board 112 via the driving shaft 1151 in the child lock structure 115 to rotate together. Because the safety arrangement is unlocked, the outward-opening linkage board 112 can drive the opening linkage board 114 to rotate together. When the opening linkage board 114 rotates, the switching swing arm piece 432 is driven via the third stay wire component 114a to rotate, the switching swing arm piece 432 drives the stop hook 423 via the lock body opening connection rod 433 to rotate, and the stop hook 423 drives the rotating tongue piece 422 to rotate so as to release the cooperation between the rotating tongue piece 422 and the U-shaped lock latch 500, thereby completing the unlocking action.
4.2) in a safety locking and child lock unlocking state, the automobile door is opened by inward-opening hand shank 220: when the inward-opening hand shank 220 is pulled for the first time, the inward-opening linkage board 113 is driven via the first stay wire component 221 to rotate in the unlocking direction. At this moment, the inward-opening linkage board 113 drives the outward-opening linkage board 112 via the driving shaft 1151 in the child lock structure 115 to rotate together. Because the safety arrangement is locked, the outward-opening linkage board 112 cannot drive the opening linkage board 114 to rotate. At the same time, when the inward-opening linkage board 113 rotates, the safety linkage board 123 can be pushed via the safety toggling pin 1132 on the toggling arm 1131 to rotate so as to release the restriction of the safety linkage board 123 on the safety swing arm mechanism 121, so that the safety swing arm mechanism 121 automatically switches from the second position to the first position to unlock the safety arrangement.
When the inward-opening hand shank 220 is pulled for the second time, the action of opening the automobile door by the inward-opening hand shank 220 is the same as that in the above safety arrangement unlocking and child lock unlocking state.4.3) in a child lock locking state, the automobile door cannot be opened by the inward-opening hand shank 220: when the inward-opening hand shank 220 is pulled, the inward-opening linkage board 113 is driven via the first stay wire component 221 to rotate in the unlocking direction. At this moment, the inward-opening linkage board 113 cannot drive the outward-opening linkage board 112 via the driving shaft 1151 in the child lock structure 115 to rotate together, so that the lock body assembly 400 cannot be controlled to perform the unlocking action.
- (V) emergency unlocking: in any case, the opening linkage board 114 can be directly driven to rotate by pulling the emergency switch stay wire 130 so as to control the lock body assembly 400 to perform the unlocking action. After the unlocking action is completed, the opening linkage board, the inward-opening linkage board and the outward-opening linkage board return back to the original positions under the action of the torsional springs.
