Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and more particularly to a door lock assembly and a vehicle having the door lock assembly. Background Technology

[0002] Currently, mainstream car companies often equip their mid-to-high-end models with feature-rich central locking systems. The working principle is as follows: a drive motor rotates, driving a cooperating electric worm gear. The driven electric worm wheel rotates, and through the engagement of a boss on the worm wheel and a locking / unlocking arm, the locking / unlocking arm moves to a predetermined locking or unlocking position. When the locking / unlocking arm is in the unlocking position, the inner and outer handles can actuate the opening linkage arm, pushing the fixed sleeve that engages with the pawl, thus unlocking the door. When the locking / unlocking arm is in the locked position, it drives the driven anti-locking rocker arm to rotate. The vertical axis movement of the opening linkage arm, which engages with the anti-locking rocker arm's hole, is restricted. At this time, the door cannot be opened using the inner and outer handles; only by pulling the locking cable of the inner handle, which rotates the locking / unlocking arm, can the door switch to the unlocking state, achieving mechanical unlocking. This central locking structure requires more mounting posts in the housing and occupies a large cavity area. Furthermore, the electric worm gear has a limited function and a relatively limited unlocking method, leaving room for improvement. Summary of the Invention

[0050] The following is for reference. Figures 1-10 The door lock assembly 100 according to an embodiment of the present invention is described, wherein a mechanical lock assembly 51 and an electric unlocking assembly 52 are provided to drive the locking linkage 53 to switch the locking assembly 3 between a unlocked state and an engaged state. When the lock is unlocked, mechanical unlocking can be performed, and when the lock is engaged, electric unlocking can be performed. The unlocking function is complete and the vehicle unlocking security is high.

[0051] like Figures 1-10 As shown, a door lock assembly 100 according to an embodiment of the present invention includes: a drive rocker arm 2, a locking component 3, and a central control mechanism.

[0052] The drive rocker arm 2 and the locking assembly 3 are provided. The drive rocker arm 2 is rotatably mounted on the door lock housing 1. That is, the drive rocker arm 2 is mounted on the door lock housing 1 and can rotate relative to the door lock housing 1. For example, the drive rocker arm 2 is rotatably connected to the fixed structure on the door lock housing 1. It should be noted that the drive rocker arm 2 is the actuator for unlocking the car door. The door is unlocked by driving the drive rocker arm 2 to rotate relative to the door lock housing 1.

[0053] The locking assembly 3 is movably mounted on the door lock housing 1 and has a switchable unlocked state and an engaged state. The locking assembly 3 is configured to push the drive rocker arm 2 to unlock the door when the lock is unlocked, and its movement trajectory is offset from that of the drive rocker arm 2 when the lock is engaged.

[0054] In other words, during the sliding process of the locking assembly 3 relative to the door lock housing 1, the locking assembly 3 can engage and disengage the drive rocker arm 2, and can switch between the two states. In the disengaged state, the locking assembly 3 can push the drive rocker arm 2 to rotate relative to the door lock housing 1, thereby unlocking the car door. However, in the engaged state, the movement trajectory of the locking assembly 3 is misaligned with that of the drive rocker arm 2, so it cannot drive the drive rocker arm 2 to rotate and thus cannot unlock the car door.

[0055] Specifically, the locking component 3 is movably installed on the door lock housing 1, and the locking component 3 has two extreme positions. In the two extreme positions, the locking component 3 is in the locked state and the unlocked state, respectively. When the locking component 3 is in the unlocked state, the locking component 3 pushes the drive rocker arm 2 to rotate, thereby unlocking the door. The unlocking method of the locking component 3 is door opening unlocking from the outside.

[0056] Furthermore, when the locking component 3 is in the locked state, the locking component 3 cannot drive the drive rocker arm 2 to rotate, that is, the door cannot be unlocked through the locking component 3, thus the locked unlocking is invalid and the door cannot be unlocked by pulling it outward. Therefore, the unlocking status of the door can be flexibly controlled according to the locked and unlocked state of the central control mechanism, making the door unlocking safer and more reliable. Moreover, the entire door unlocking transmission chain is short, the unlocking efficiency is high, the applicability is stronger, and the structure is simple, the size is compact, and the development cost is low.

[0057] The central control mechanism includes a mechanical lock assembly 51, an electric unlocking assembly 52, and a locking linkage 53. The mechanical lock assembly 51 and the electric unlocking assembly 52 are used to drive the locking linkage 53 to switch the locking assembly 3 between the unlocked state and the locked state. In other words, the mechanical lock assembly 51 and the electric unlocking assembly 52 can act as a driving structure to drive the locking linkage 53 to switch the locking assembly 3 from the unlocked state to the locked state, or from the locked state to the unlocked state, thereby realizing the locking and unlocking of the locking assembly 3.

[0058] Specifically, the mechanical lock assembly 51 and the electric unlocking assembly 52 can be connected to the locking link 53 respectively. The mechanical lock assembly 51 can be connected to the left side of the locking link 53. The mechanical lock assembly 51 is used to mechanically unlock and lock the locking assembly 3. Specifically, the mechanical lock assembly 51 pushes the left side of the locking link 53 to drive the locking link 53 to move. At the same time, the locking link 53 acts on the locking assembly 3 to move the locking assembly 3 from the unlocked state to the locked state, thereby realizing the mechanical switching of the state of the locking assembly 3.

[0059] Furthermore, the electric opening component 52 is connected to the middle position of the locking link 53. The electric opening component 52 is used to electrically unlock and lock the locking component 3. Specifically, the electric opening component 52 pushes the middle position of the locking link 53 to drive the locking link 53 to move. At the same time, the locking link 53 acts on the locking component 3 to move the locking component 3 from the unlocked state to the locked state, thereby realizing the electric switching of the state of the locking component 3.

[0060] Therefore, by setting the mechanical lock assembly 51 and the electric unlocking assembly 52 to drive the locking linkage 53 to move, the position of the locking assembly 3 relative to the drive rocker arm 2 is switched. In the unlocked state, the locking assembly 3 pushes the drive rocker arm 2 to unlock the door. The door can be unlocked selectively as needed, and the transmission distance is short and the transmission efficiency is better.

[0061] According to an embodiment of the present invention, the door lock assembly 100 is configured to cooperate between the central control mechanism, the drive rocker arm 2 and the locking component 3, thereby realizing the switching of locking and unlocking of the central control mechanism, and enabling both electric and mechanical unlocking functions. The transmission distance is short, the transmission efficiency is better, the reliability and durability of the door lock assembly 100 are improved, and the applicability is strong.

[0062] In some embodiments, the electric opening assembly 52 includes an electric opening drive 521 and an electric opening worm gear 522. The output end of the electric opening drive 521 is provided with an electric opening worm 523. The electric opening worm gear 522 is rotatably mounted on the door lock housing 1. The electric opening worm 523 meshes with the electric opening worm gear 522 for transmission. The electric opening worm gear 522 is adapted to push the locking link 53 to move during rotation, thereby driving the locking assembly 3 to move. That is, the electric opening drive 521 drives the electric opening worm 523 to rotate, thereby driving the electric opening worm gear 522 to rotate. The electric opening worm gear 522 pushes the locking link 53 to move, thereby driving the locking assembly 3 to move, thus realizing the electric drive of the locking assembly 3 to move.

[0063] Specifically, the electric worm gear 522 is mounted on the door lock housing 1 and is rotatable relative to the door lock housing 1. For example, if there is a mounting post 11 on the door lock housing 1, the electric worm gear 522 is provided with a mounting hole. The electric worm gear 522 is mounted on the mounting post 11 of the door lock housing 1 through the mounting hole, and the electric worm gear 522 can rotate around the mounting post 11. The electric drive component 521 can be a drive motor. The output end of the motor shaft of the drive motor is coaxially connected to the electric worm gear 523, and the electric worm gear 523 meshes with the electric worm gear 522 for transmission. In this way, the driving force of the drive motor is transmitted to the electric worm gear 522 through the electric worm gear 523, realizing the rotation of the electric worm gear 522. After the electric worm gear 522 rotates, it pushes the locking link 53 to move. The locking link 53 drives the locking assembly 3 to move. The overall movement process of the electric drive is simple and convenient to switch.

[0064] In some embodiments, the electrically operated assembly 52 further includes a locking slide bar 524, which is slidably mounted on the door lock housing 1 and has a locked position and an unlocked position. That is, the locking slide bar 524 has a locked position and an unlocked position during its sliding relative to the door lock housing 1. Specifically, the locking slide bar 524 is slidably mounted on the door lock housing 1, such as... Figure 2 As shown, the door lock housing 1 is provided with a mounting groove 12, and the locking slide rod 524 is slidably installed in the mounting groove 12. The locking slide rod 524 has two extreme positions, in which the locking slide rod 524 is locked and unlocked respectively.

[0065] The electrically operated worm gear 522 is configured to push the locking link 53 away from the locking assembly 3 and drive the locking slide bar 524 to the locking position when it rotates in the first direction. The electrically operated worm gear 522 is configured to push the locking link 53 against the locking assembly 3 when it rotates in the second direction. When the locking slide bar 524 is in the locking position, it is used to circumferentially limit and lock the electrically operated worm gear 522 when it rotates to the maximum position in the second direction.

[0066] In other words, when the electric worm gear 522 rotates in the first direction, it pushes the locking link 53 to move the locking slide 524 to the locking position, thereby switching the locking slide 524 from unlocking to locking. When the electric worm gear 522 rotates in the second direction, and when it rotates to the maximum position, the electric worm gear 522 locks with the locking slide 524 in the locking position, thereby achieving a limit lock between the two.

[0067] The first direction can be clockwise, and the second direction can be counterclockwise. When the electric worm gear 522 rotates clockwise, it pushes the locking link 53 to move to the right and disengage from the locking assembly 3. At the same time, the locking link 53 drives the locking slide 524 to move to the right limit position, which is the locking position of the locking slide 524. When the electric worm gear 522 rotates counterclockwise, it pushes the locking link 53 to move to the left and press against the locking assembly 3, and pushes the locking assembly 3 to the upper safe state. When the electric worm gear 522 rotates to the maximum position and is circumferentially limited by the locking link 53, the electric worm gear 522 can be circumferentially limited and locked. At this time, the locking assembly 3 is in the upper safe state and the door lock cannot be opened by mechanical means.

[0068] In some embodiments, the door lock assembly 100 further includes a first elastic member 6, which is installed between the door lock housing 1 and the locking slide bar 524. The first elastic member 6 is used to apply an elastic force to the locking slide bar 524 to switch from the locked position to the unlocked position. Thus, by applying an elastic force to the locking slide bar 524 through the first elastic member 6, the locking slide bar 524 can be switched to the unlocked position.

[0069] Specifically, such as Figures 5-9As shown, the first elastic element 6 is installed inside the locking slide rod 524. One end of the first elastic element 6 abuts against the locking slide rod 524, and the other end abuts against the door lock housing 1. The first elastic element 6 can be a spring or similar structure. When the locking linkage 53 pushes the locking slide rod 524 to the right to the locked position, the spring is in a compressed state, and the door lock housing 1 applies a leftward elastic force to the spring. The electric opening worm gear 522 is provided with a coaxially connected center spring 526. The center spring 526 applies a clockwise pushing force to the electric opening worm gear 522, so that after the electric opening worm gear 522 disengages from the locking slide rod 524 and is unlocked, the spring applies a leftward elastic force to the locking slide rod 524, which can return the locking slide rod 524 to the unlocked position, thereby releasing the limiting effect of the locking slide rod 524 on the electric opening worm gear 522.

[0070] In some embodiments, the locking slide bar 524 has a circumferential limiting surface 5241 and a bending structure 5242 for circumferentially limiting the electrically operated worm gear 522. The electrically operated worm gear 522 has a circumferential stop surface 5221, which is adapted to limit and press against the circumferential limiting surface 5241 when the electrically operated worm gear 522 rotates to its maximum position in the second direction. The electrically operated worm gear 522 has a limiting protrusion 5222, which is adapted to press against the bending structure 5242 when the electrically operated worm gear 522 rotates in the second direction to restrict the locking slide bar 524 from switching from the locked position to the unlocked position.

[0071] Specifically, such as Figure 2 As shown, the right end of the locking slide bar 524 is provided with a bending structure 5242, which is bent toward the locking link 53. A circumferential limiting surface 5241 is formed on the left side of the bending structure 5242. Figure 7 , Figure 9 As shown, a limiting protrusion 5222 is provided on the side of the electric opening worm gear 522 near the locking slide bar 524. The limiting protrusion 5222 protrudes from the surface of the electric opening worm gear 522 and extends circumferentially along the electric opening worm gear 522. A circumferential stop surface 5221 is formed on one side of the rotation center of the electric opening worm gear 522. When the electric opening worm gear 522 rotates counterclockwise, the limiting protrusion 5222 rotates counterclockwise and presses against the bent structure 5242 of the locking slide bar 524. When the electric opening worm gear 522 rotates to its maximum position, the circumferential stop surface 5221 presses against the circumferential limiting surface 5241. This can limit the locking slide bar 524 of the electric opening worm gear 522, thereby restricting the locking slide bar 524 from switching from the locked position to the unlocked position. Its pressing and limiting is stable and reliable.

[0072] Furthermore, after the electrically operated worm gear 522 and the locking slide rod 524 are circumferentially limited, the electrically operated worm gear 522 stops moving. At this time, the neutral spring 526 applies an elastic force to the electrically operated worm gear 522, causing it to rotate in the neutral direction, thus resetting the electrically operated worm gear 522. Figure 8 As shown, the electrically operated worm gear 522 disengages from the locking slide bar 524, and the locking slider moves to the left and then resets, as... Figure 9 As shown.

[0073] In some embodiments, the locking link 53 is provided with a 531, and the locking slide bar 524 is provided with a pushing protrusion 525. The pushing protrusion 525 extends into the movable groove 531. The movable groove 531 has a first inner end face 5311 and a second inner end face 5312 that are relatively distributed. The locking link 53 is adapted to push the pushing protrusion 525 through the first inner end face 5311 of the movable groove 531 to drive the locking slide bar 524 to the locking position. When the locking position is unlocked, the pushing protrusion 525 presses against the second inner end face 5312. That is, the locking slide bar 524 can be switched between the locking position and the unlocking position by pushing the pushing protrusion 525 through the first inner end face 5311 or the second inner end face 5312 of the movable groove 531, respectively.

[0074] Specifically, the locking slide bar 524 is located on the lower side of the locking link 53, and the left side region of the locking link 53 is provided with a movable groove 531, such as... Figure 2 As shown, the movable groove 531 can be installed through the vertical direction. The top of the locking slide rod 524 is provided with a pushing protrusion 525. Both the pushing protrusion 525 and the movable groove 531 can be constructed as square structures, and the outer dimensions of the pushing protrusion 525 are smaller than the outer dimensions of the movable groove 531. During installation, the pushing protrusion 525 is extended into the movable groove 531 and can slide relative to the movable groove 531. The movable groove 531 has a first inner end face 5311 and a second inner end face 5312. The first inner end face 5311 and the second inner end face 5312 are distributed opposite to each other in the left-right direction. Figure 5 As shown, pushing the protrusion 525 to the right on the first inner end face 5311 can move the locking slide bar 524 from the unlocked position to the locked position, and vice versa. Figure 6 As shown, the second inner end face 5312 of the movable groove 531 pushes the protrusion 525 to the left, which can drive the locking slide bar 524 from the locked position to the unlocked position.

[0075] Therefore, through the cooperation of the movable groove 531 and the pushing protrusion 525, the locking link 53 can drive the locking slide bar 524 to switch between the locked position and the unlocked position. The switching method is simple and convenient. Moreover, by placing the locking slide bar 524 on the lower side of the locking link 53, the required volume of the locking slide bar 524 is reduced, leaving more space for the central control mechanism on the right side. This facilitates the installation and expansion of more structures and is conducive to the development trend of miniaturization, compactness and functional enrichment of the door lock assembly 100.

[0076] In some embodiments, the drive rocker arm 2 is provided with an unlocking groove 21, and the electric opening worm gear 522 is provided with an unlocking protrusion 5223. The unlocking protrusion 5223 extends into the unlocking groove 21 and is adapted to press against the inner wall of the unlocking groove 21 when the electric opening worm gear 522 rotates in the second direction to push the drive rocker arm 2 to unlock. That is, through the pressing cooperation between the unlocking protrusion 5223 and the unlocking groove 21, the electric opening worm gear 522 can push the drive rocker arm 2 to rotate, thereby unlocking the door.

[0077] Specifically, such as Figure 10 As shown, the drive rocker arm 2 is provided with an unlocking groove 21, which extends circumferentially along the rotation axis of the drive rocker arm 2. The electric unlocking worm gear 522 is provided with an unlocking protrusion 5223 on the side near the drive rocker arm 2. The unlocking protrusion 5223 protrudes along the surface of the electric unlocking worm gear 522. The unlocking protrusion 5223 can be constructed as a square, and the four sides of the unlocking protrusion 5223 are provided with transition arcs, so that the structure of the unlocking protrusion 5223 is smooth. When the electric unlocking worm gear 522 rotates in the counterclockwise direction, the unlocking protrusion 5223 presses against the inner wall of the unlocking groove 21 to push the drive rocker arm 2 to rotate in the counterclockwise direction, thereby realizing electric unlocking.

[0078] In some embodiments, the electrically operated worm gear 522 is provided with a drive protrusion 5224, and the locking link 53 is provided with a push groove 532. The drive protrusion 5224 extends into the push groove 532, and a first push surface 5321 and a second push surface 5322 are formed in the push groove 532. The electrically operated worm gear 522 is configured such that when it rotates in a first direction, the drive protrusion 5224 presses against the first push surface 5321, and when it rotates in a second direction, the drive protrusion 5224 presses against the second push surface 5322. That is, by rotating the electrically operated worm gear 522 in both directions, the drive protrusion 5224 drives the first push surface 5321 or the second push surface 5322 to move, thereby achieving the switching of the locking link 53 moving to the left or to the right.

[0079] Specifically, such as Figure 10As shown, the electrically operated worm gear 522 has a drive protrusion 5224 on the side near the locking link 53. The drive protrusion 5224 protrudes along the surface of the electrically operated worm gear 522. The drive protrusion 5224 can be square, and all four sides of the drive protrusion 5224 have transition arcs, making the structure of the drive protrusion 5224 smooth. The drive protrusion 5224 is arranged opposite to the unlocking protrusion 5223. The middle area of ​​the locking link 53 has a push groove 532. The push groove 532 can extend in the left and right direction and is open on the side facing the drive protrusion 5224, which facilitates the drive protrusion 5224 and even the push groove 532 to drive the locking link 53 to move. The push groove 532 forms a first push surface 5321 and a second push surface 5322. The first push surface 5321 and the second push surface 5322 are distributed opposite to each other in the left and right direction, and they are inclined in the direction away from each other. During installation, the push protrusion 525 is extended into the push groove 532. Figure 5 As shown, when the electrically operated worm gear 522 rotates clockwise, the drive protrusion 5224 presses against the first pushing surface 5321, causing the locking linkage 53 to move to the right; conversely, when it rotates counterclockwise, the locking linkage 53 moves to the right. Figure 6 As shown, the electric worm gear 522 rotates counterclockwise, driving the protrusion 5224 to press against the second pushing surface 5322, which in turn drives the locking link 53 to move to the left.

[0080] In some embodiments, the mechanical lock assembly 51 includes a lock cylinder connecting arm 511 and a lock cylinder driving arm 512. Both the lock cylinder connecting arm 511 and the lock cylinder driving arm 512 are rotatably mounted on the door lock housing 1. The lock cylinder connecting arm 511 is adapted to drive the lock cylinder driving arm 512 to drive the locking link 53 to move under the user's drive. That is, the user drives the lock cylinder connecting arm 511 to drive the lock cylinder driving arm 512 to rotate and drive the locking link 53 to move, thereby realizing the switching of the locking assembly 3 between the unlocked state and the locked state.

[0081] Specifically, both the lock cylinder connecting arm 511 and the lock cylinder driving arm 512 are rotatably mounted on the door lock housing 1. In actual design, such as Figure 2 As shown, the left side of the door lock housing 1 is provided with a mounting slot 13. The lock cylinder connecting arm 511 and the lock cylinder driving arm 512 are concentrically installed in the mounting slot 13 and can rotate relative to the door lock housing 1. The locking link 53 is provided with a left connecting shaft hole 534 at one end near the locking driving arm 512. The left connecting shaft hole 534 is connected to the lock cylinder driving arm 512, so that the left side of the locking driving arm 512 is connected to the locking link 53. When there is no external mechanical force, the locking link 53 is in the leftmost position and the locking link 53 pushes the locking assembly 3 to the upper safe state. When the user needs to unlock, the user can insert the mechanical key into the key hole to drive the lock cylinder connecting arm 511 to rotate clockwise, which drives the locking link 53 to move to the right, thereby realizing the unlocking of the locking assembly 3.

[0082] In some embodiments, the locking assembly 3 includes a pawl 31 and a pawl slider 32, both of which are rotatably mounted on the door lock housing 1. The pawl slider 32 is slidable relative to the pawl 31. The pawl slider 32 is adapted to push the drive rocker arm 2 to rotate when the lock is released. When the lock is engaged, the rotation trajectory of the pawl slider 32 about the rotation axis of the pawl 31 is offset from that of the drive rocker arm 2.

[0083] In other words, when the door is unlocked, the pawl slider 32 rotates to drive the rocker arm 2 to rotate, thus unlocking the door. When the door is engaged, the trajectory of the pawl slider 32 rotating around the pawl 31 is offset from that of the rocker arm 2, so the door cannot be unlocked. Thus, the door unlocking can be switched by the cooperation between the pawl slider 32 and the rocker arm 2.

[0084] Specifically, both the pawl 31 and the pawl slider 32 are movably mounted on the door lock housing 1. In the actual design, the pawl 31 has a mounting hole, through which it is mounted on the mounting post 11 of the door lock housing 1. The pawl 31 can rotate around the mounting post 11. The pawl slider 32 is movably connected to the upper side of the pawl 31, and the rotation of the pawl 31 can drive the pawl slider 32 to rotate. Thus, when the lock is released, if... Figure 4 , 5 As shown, after the pawl 31 rotates, it drives the pawl slider 32 to rotate, and the pawl slider 32 pushes the drive rocker arm 2 to rotate, thereby unlocking the car door.

[0085] And, when in an insured state, such as Figure 3 , 6 As shown in Figure 8, because the rotation trajectory of the pawl slider 32 is misaligned with that of the drive rocker arm 2, the rotation of the pawl 31 drives the pawl slider 32 to rotate but cannot drive the drive rocker arm 2 to rotate. Therefore, the door cannot be unlocked by the pawl 31, and the unlocking is ineffective.

[0086] In some embodiments, the locking assembly 3 further includes an elastic reset member 33, which presses against the pawl 31 and the pawl slider 32. The elastic reset member 33 is used to push the pawl slider 32 to move so that the locking assembly 3 switches from the locked state to the unlocked state. That is, by applying an elastic force to the pawl slider 32 through the elastic reset member 33, the pawl slider 32 switches to the unlocked state so that the door can be unlocked in the unlocked state. Thus, when the mechanical lock assembly 51 or the electric unlocking assembly 52 drives the locking linkage 53 to separate from the pawl slider 32, the elastic reset member 33 can make the pawl slider 32 move automatically to realize the switch from the locked state to the unlocked state.

[0087] Specifically, the elastic reset member 33 presses against the pawl 31 and the pawl slider 32. In actual design, a fixed boss 321 can be provided on the pawl slider 32, and the elastic reset member 33 is sleeved on the fixed boss 321. One end of the elastic reset member 33 abuts against the pawl slider 32, and the other end abuts against the door lock housing 1. The elastic reset member 33 can be a pawl spring. In the locked state, the pawl slider 32 pushes the pawl spring, and the pawl spring applies an elastic force to the pawl slider 32. When the locking linkage 53 moves to the right limit position, the pawl spring pushes the pawl 31 relative to the pawl slider 32 to the unlocked state through the elastic force. Thus, the locking assembly 3 can be switched from the locked state to the unlocked state. The movement process is simple, the switching is convenient and free, and the repeatability is good.

[0088] In addition, the pawl 31 is also provided with a third return spring 311 coaxially distributed, which is used to reset the pawl 31 after it is activated, so as to realize the reset after the door is pulled outward to unlock.

[0089] In some embodiments, the door lock assembly 100 further includes a child lock mechanism 4 and a rotary rocker arm 7.

[0090] The child lock mechanism 4 includes a rocker arm 41 and a first clutch lever 42. The rocker arm 41 is rotatably mounted on the door lock housing 1 and coaxially arranged with the drive rocker arm 2. The first clutch lever 42 is movably mounted inside the door lock housing 1 and has an open child lock position and an closed child lock position. The rocker arm 41 is adapted to drive the first clutch lever 42 to unlock the drive rocker arm 2 when the first clutch lever 42 is in the closed child lock position. When the first clutch lever 42 is in the open child lock position, the trajectory of the rocker arm 41 is offset from that of the drive rocker arm 2.

[0091] In other words, during the movement of the first clutch lever 42 relative to the door lock housing 1, the first clutch lever 42 has a child lock closed position and a child lock open position. When the child lock is closed, the rocker arm 41 pushes the first clutch lever 42 to drive the drive rocker arm 2 to rotate relative to the door lock housing 1, thereby unlocking the door. When the child lock is open, the trajectory of the rocker arm 41 driving the first clutch lever 42 to rotate is misaligned with the drive rocker arm 2, and the door cannot be unlocked. That is, the door unlocking can be switched through the cooperation between the first clutch lever 42 and the drive rocker arm 2.

[0092] Specifically, the door lock housing 1 is provided with a mounting post 11, and the rocker arm 41 is provided with a mounting hole. The rocker arm 41 is coaxially mounted to the mounting post 11 with the drive rocker arm 2 through the mounting hole and rotates around the mounting post 11. The first clutch rod 42 is slidably connected to the rocker arm 41, such as... Figures 3-6As shown, the rocker arm 41 has a first movable groove 412, and the first clutch lever 42 has a first movable part 421. The first movable part 421 extends into the first movable groove 412 and slidably engages with the rocker arm 41. The first clutch lever 42 has two extreme positions. When the first clutch lever 42 moves to the right extreme position, it separates from the drive rocker arm 2, which is the child lock unlocking position. When the first clutch lever 42 moves to the left extreme position, it contacts the drive rocker arm 2, which is the child lock deactivating position. The rotation of the rocker arm 41 drives the first clutch lever 42 to push the drive rocker arm 2 to rotate, thereby unlocking the door. The door unlocking mechanism, where the rocker arm 41 drives the drive rocker arm 2 to rotate, is an inward-pulling unlocking mechanism.

[0093] The rotating rocker arm 7 is rotatably mounted on the door lock housing 1. The rotating rocker arm 7 is connected to the locking linkage 53. The locking linkage 53 is adapted to drive the first clutch lever 42 from the child lock position to the child lock position while driving the locking assembly 3 to switch from the unlocked state to the locked state. In other words, by rotating the rotating rocker arm 7 relative to the door lock housing 1, the locking linkage 53 can be switched between the unlocked state and the locked state, and the first clutch lever 42 can be switched between the locked position and the unlock position. Thus, the rotating rocker arm 7 can realize two modes of movement, thereby reducing the number of parts in the door lock assembly 100.

[0094] Specifically, the rotating rocker arm 7 is located on the right side of the rocker arm 41, and the door lock housing 1 is provided with a mounting post 11. The rotating rocker arm 7 is provided with a mounting hole, through which the rotating rocker arm 7 can be rotatably mounted on the fixed post. The locking link 53 is provided with a right connecting shaft hole 535 at one end near the rotating rocker arm 7. The rotating rocker arm 7 is provided with a connecting shaft 71, and the right connecting shaft hole 535 is connected to the connecting shaft 71, so that one end of the rotating rocker arm 7 is connected to the right end of the locking link 53. After the rotating rocker arm 7 rotates counterclockwise, it pushes the locking link 53 to move to the left to drive the locking assembly 3 to switch from the unlocked state to the locked state. The other end of the rotating rocker arm 7 is connected to the first clutch lever 42. The first clutch lever 42 moves away from the rocker arm 41, that is, it switches from the child lock position to the child lock position. At this time, the door cannot be unlocked by driving the rocker arm 2 to rotate through the locking assembly 3 and the rocker arm 41.

[0095] In some embodiments, the child lock mechanism 4 further includes a child lock worm gear and a second clutch lever 44. The child lock worm gear is connected to the second clutch lever 44, and the second clutch lever 44 is slidably connected to the rocker arm 41. The child lock worm gear is used to push the second clutch lever 44 to drive the rocker arm 41 to rotate. In other words, the child lock worm gear can push the second clutch lever 44 to drive the rocker arm 41 to rotate, thereby driving the drive rocker arm 2 to rotate, thereby unlocking the car door.

[0096] Specifically, the door lock housing 1 is provided with a mounting post 11, and the child lock worm gear is provided with a mounting hole. The child lock worm gear can be rotatably mounted to the fixed post through the mounting hole. The child lock worm gear is connected to the second clutch lever 44. Figure 4 As shown, the rocker arm 41 is provided with a second movable groove 413, and the second clutch lever 44 is provided with a second movable part 441. The second movable part 441 extends into the second movable groove 413 and is slidably engaged with the rocker arm 41. When the child lock worm gear rotates clockwise, it drives the second clutch lever 44 to push the rocker arm 41 to rotate clockwise, thereby driving the drive rocker arm 2 to rotate, so as to realize the automatic unlocking of the car door.

[0097] And / or, the rocker arm 41 is connected to a drive cable 411 for pulling the rocker arm 41 to rotate. Specifically, the drive cable 411 is connected to one end of the rocker arm 41, and the drive cable 411 is spaced apart from the rotation axis of the rocker arm 41, so that the drive cable 411 can pull the rocker arm 41 to rotate around its own rotation axis. When the child lock is engaged, pulling the drive cable 411 drives the rocker arm 41 to rotate, thereby driving the first clutch lever 42 to push the drive rocker arm 2 to rotate, which can realize the door can be unlocked from the inside.

[0098] Among them, such as Figure 2 As shown, it should be noted that the rocker arm 41 is also provided with a first return spring 414 coaxially distributed for resetting after the rocker arm 41 moves, and the drive rocker arm 2 is provided with a second return spring 22 coaxially distributed for resetting after the drive rocker arm 2 moves. Furthermore, the door lock assembly 100 is also provided with a motor mounting housing cover plate 9, and the door lock housing 1 is connected to the motor mounting housing cover plate 9 to achieve enclosure and protection of various door lock components.

[0099] In some embodiments, the door lock assembly 100 further includes a switching elastic element 8, which is connected to the rotating rocker arm 7. The switching elastic element 8 is used to apply an elastic force to the rotating rocker arm 7 to continue rotating when the electric opening assembly 52 drives the locking link 53 to move to the maximum position. That is, when the electric opening assembly 52 drives the locking link 53 to move to the maximum position, the switching elastic element 8 applies an elastic force in the same direction to the rotating rocker arm 7 to make the locking link 53 move to a set position.

[0100] Specifically, the switching elastic element 8 is connected to the rotating rocker arm 7. The switching elastic element 8 is constructed as a switching spring. One end of the switching spring is connected to the rotating rocker arm 7, and the other end is connected to the door lock housing 1. When the locking link 53 drives the rotating rocker arm 7 to rotate, the switching spring changes from gradually compressing to opening outward as the rotating rocker arm 7 rotates. When the electric opening component 52 cannot push the locking link 53 to continue moving, the thrust of the switching spring pushes the rotating rocker arm 7 to continue rotating, so that the locking link 53 continues to move to the set position. This allows the locking component 3 to switch between unlocking and locking, and the first clutch lever 42 to switch between the child lock position and the child lock position.

[0101] In some embodiments, the locking link 53 has at least one hollow hole 533 for energy absorption and noise reduction, such as... Figure 2-6 As shown, multiple hollow holes 533 are provided, and the multiple hollow holes 533 are spaced apart on the locking link 53. The hollow holes 533 are triangular in shape, and the adjacent sides of the hollow holes 533 are arranged parallel to each other, which can ensure the structural strength requirements of the locking link 53. Thus, by setting multiple hollow holes 533, when the locking link 53 is in contact, the multiple hollow holes 533 can slowly release the impact energy and reduce noise. Compared with the solid structure, the hollow structure is beneficial to improving the user experience.

[0102] The present invention also proposes a vehicle.

[0103] The vehicle according to the embodiments of the present invention is provided with a door lock assembly 100 of any of the above embodiments, which is configured to cooperate between the central control mechanism, the drive rocker arm 2 and the locking component 3, realize the switching of locking and unlocking of the central control mechanism, and realize electric unlocking and mechanical unlocking functions. The transmission distance is short, the transmission efficiency is better, the reliability and durability of the door lock assembly 100 are improved, and the applicability is strong.
