[0055] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle, i.e., the Z direction.

[0056] The following is for reference. Figures 1-18 The door lock assembly 100 according to an embodiment of the present invention is described, which reduces the volume of the door lock assembly 100, thereby reducing the installation space required for the door lock assembly 100, improving vehicle lightweighting, and reducing installation costs.

[0057] like Figures 1-18 As shown, the door lock assembly 100 according to an embodiment of the present invention includes: a door lock housing 1, an electric opening worm gear 2, a locking linkage 3, and an electric opening locking rod 4.

[0058] The door lock housing 1 is provided with a rotatable electric opening rocker arm 5. The electric opening locking rod 4 is slidably installed on the door lock housing 1 and has a locked position. The locking link 3 is slidably connected to the electric opening locking rod 4. The locking link 3 has a locked state and an unlocked state. When the electric opening locking rod 4 is in the locked position, when the electric opening worm gear 2 pushes the locking link 3 to switch to the locked state and moves to the limit position, the electric opening locking rod 4 limits and locks the electric opening worm gear 2.

[0059] Among them, vehicle door locks are an important component in ensuring vehicle safety. The structural principle of vehicle door locks directly affects the ease of use and safety of the vehicle. The vehicle door lock unlocks or unlocks by rotating the electric worm gear 2, which drives the locking linkage 3 to move. This can prevent accidental door opening due to accidental contact with the door lock, thus improving safety. Furthermore, the electric worm gear 2 can directly drive the electric rocker arm 5 to rotate, thereby opening the door and enabling multiple ways to open the door, improving ease of use.

[0060] Specifically, the door lock assembly 100 includes a door lock housing 1, within which a cavity is formed. This cavity can be used to install components required for the operation of the door lock assembly 100. The door lock housing 1 also provides waterproofing and dustproofing for the internal components. The door lock assembly 100 can be installed with the vehicle door through the door lock housing 1. The door lock assembly 100 contains an electrically operated rocker arm 5, which is rotatable relative to the door lock housing 1. When the rocker arm 5 rotates, the vehicle door can be opened. The door lock assembly 100 also includes a locking link 3, which is located inside the door lock housing 1 and is movable relative to it. The locking link 3 has a locked state and an unlocked state. When the locking link 3 is moved to the locked state, the vehicle door lock is locked, preventing accidental opening of the door and improving safety. When the locking link 3 is moved to the unlocked state, the vehicle door can be opened and closed normally.

[0061] Furthermore, the door lock assembly 100 is also equipped with an electrically operated locking rod 4, which is also located inside the door lock housing 1 and is slidable relative to the door lock housing 1. The locking link 3 is slidably connected to the electrically operated locking rod 4, and the electrically operated locking rod 4 is provided with a locked position. The door lock assembly 100 is also equipped with an electrically operated worm gear 2, which can push the locking link 3 to switch between the unlocked state and the locked state. When the electrically operated worm gear 2 pushes the locking link 3 to move to the locked state, the vehicle door lock is locked, which can prevent accidental opening of the door and improve the safety of use.

[0062] Furthermore, when the electric worm gear 2 pushes the locking link 3 to the unlocked state, the door can be opened and closed normally. When the electric locking lever 4 is in the locked position, the electric worm gear 2 can push the locking link 3 to switch from the unlocked state to the locked state. When the electric worm gear 2 moves to the limit position, the electric locking lever 4 can limit and lock the electric worm gear 2, thereby limiting the running position of the electric worm gear 2 and ensuring the overall operational reliability of the door lock assembly 100.

[0063] According to an embodiment of the present invention, the door lock assembly 100 is slidably connected to the electric unlocking locking rod 4 via the locking link 3, thereby reducing the volume of the door lock assembly 100, reducing the installation space required for the door lock assembly 100, improving vehicle lightweighting, reducing installation costs, improving performance, and expanding applicability.

[0064] In some embodiments, the electrically operated worm gear 2 is configured to drive the electrically operated locking rod 4 to the locking position when the locking linkage 3 is switched to the unlocked state.

[0065] Specifically, the electric opening worm gear 2 is located inside the door lock housing 1 and is movable relative to the locking link 3, allowing the electric opening worm gear 2 to push the locking link 3 to switch between the locked and unlocked states. When the electric opening worm gear 2 pushes the locking link 3 to the locked state, the vehicle door lock is engaged, preventing accidental opening of the door and improving safety. When the electric opening worm gear 2 pushes the locking link 3 to the unlocked state, the door can be opened and closed normally to meet different usage needs. When the electric opening worm gear 2 pushes the locking link 3 from the locked state to the unlocked state, the locking link 3 drives the electric opening locking rod 4 to move towards the locked position. This allows the electric opening worm gear 2 to push the locking link 3 to switch to the locked state and move to its limit position, at which point the electric opening locking rod 4 can limit and lock the electric opening worm gear 2, ensuring operational reliability.

[0066] In some embodiments, the electric opening worm gear 2 is rotatably mounted on the door lock housing 1. The electric opening worm gear 2 is configured to push the locking link 3 to switch to the unlocked state when rotating in a first direction, and to push the locking link 3 to switch to the locked state when rotating in a second direction.

[0067] Specifically, the door lock assembly 100 is equipped with an electrically operated worm gear 2, which is located inside the door lock housing 1 and is rotatable relative to the door lock housing 1. The electrically operated worm gear 2 has an intermediate position and can rotate in a first direction or a second direction. When the electrically operated worm gear 2 rotates in the first direction, it can push the locking linkage 3 to switch from the locked state to the unlocked state. The locking linkage 3 is slidably connected to the electrically operated locking rod 4, so that the electrically operated locking rod 4 can also move toward the locked position. When the locking linkage 3 switches to the unlocked position... When in the unlocked state, the electric worm gear 2 returns to the middle position, and the door lock is unlocked, allowing the door to be opened or closed normally. When the electric worm gear 2 rotates in the second direction, it can push the locking linkage 3 from the unlocked state to the locked state, and the electric locking lever 4 remains in the locked position. When the electric worm gear 2 rotates to the limit position in the second direction, the electric locking lever 4 can limit and lock the electric worm gear 2. When the locking linkage 3 switches to the locked state, the electric worm gear 2 returns to the middle position, and the door lock is locked, satisfying multiple needs.

[0068] Furthermore, one of the first direction and the second direction can be set to a clockwise direction and the other can be set to a counterclockwise direction. That is, the first direction can be set to a clockwise direction and the second direction can be set to a counterclockwise direction, or the first direction can be set to a counterclockwise direction and the second direction can be set to a clockwise direction. In this embodiment, the first direction always refers to the clockwise direction and the second direction always refers to the counterclockwise direction.

[0069] In some embodiments, the door lock assembly 100 further includes a first elastic element 6, and the electric unlocking stop lever 4 also has an unlocked position. The first elastic element 6 is installed between the door lock housing 1 and the electric unlocking stop lever 4, and the first elastic element 6 is used to apply an elastic force to the electric unlocking stop lever 4 to switch from the locked position to the unlocked position.

[0070] Specifically, such as Figures 1-3 and Figure 5 As shown, the door lock assembly 100 is also provided with a first elastic element 6, which can be a spring or the like. The first elastic element 6 is installed between the door lock housing 1 and the electrically operated locking rod 4, and the electrically operated locking rod 4 also has an unlocked position. When the electrically operated locking rod 4 is in the unlocked position, it can slide with the locking link 3. When the first elastic element 6 is compressed, it can generate a reaction force to restore its original shape. The locking link 3 and the electrically operated locking rod 4 are slidably connected. When the electrically operated worm gear 2 rotates in the first direction, it can push the locking link 3 to move, so that the locking link 3 switches from the locked state to the unlocked state. When switched to the unlocked state, the electrically operated locking rod 4 can also slide relative to the door lock housing 1 along with the locking link 3, thereby allowing the electrically operated locking rod 4 to move from the unlocked position to the locked position. At this time, the first elastic element 6 is compressed by the force of the electrically operated locking rod 4. When the electrically operated worm gear 2 pushes the locking link 3 to switch from the unlocked state to the locked state, the first elastic element 6 can apply a force to the electrically operated locking rod 4 to restore its deformation, so that the electrically operated locking rod 4 can move from the locked position to the unlocked position, thereby allowing the electrically operated locking rod 4 to reset. Its structure is simple, the installation cost is low, and the operational reliability is guaranteed.

[0071] In some embodiments, the door lock housing 1 is provided with a mounting shell portion 11, and a mounting cavity 111 is formed in the mounting shell portion 11. The electric unlocking and locking rod 4 is slidably mounted in the mounting cavity 111. One end of the first elastic member 6 abuts against the inner wall of the mounting cavity 111 and the other end abuts against the electric unlocking and locking rod 4.

[0072] Specifically, the door lock housing 1 is used to install the components required for the operation of the door lock assembly 100, and as such... Figures 1-3 and Figures 5-7As shown, the door lock housing 1 is provided with a mounting shell portion 11, which can be a rectangular shell or the like. A mounting cavity 111 is formed within the mounting shell portion 11. One end of the mounting cavity 111 is open, and the open side faces the locking linkage 3. The electrically operated locking rod 4 matches the mounting cavity 111, allowing the electrically operated locking rod 4 to be installed in the mounting cavity 111 through the open opening. The electrically operated locking rod 4 can slide relative to the mounting cavity 111. A first elastic member 6 is disposed within the mounting cavity 111, and one end of the first elastic member 6 presses against the mounting cavity 111. The inner wall of the electric locking rod 4 is pressed against the electric locking rod 4 at the other end, so that when the electric locking rod 4 slides relative to the mounting cavity 111, the electric locking rod 4 can apply a force to the first elastic member 6, or the first elastic member 6 can apply an elastic force to the electric locking rod 4, so that the electric locking rod 4 slides relative to the mounting cavity 111, thereby allowing the electric locking rod 4 to switch between the locked position and the unlocked position. The structure is simple, the installation cost is low, and the mounting cavity 111 can restrict the movement direction of the electric locking rod 4, ensure the movement path of the electric locking rod 4, and improve the operational reliability.

[0073] In some embodiments, the mounting housing 11 has a movable opening 112 at one end facing the electrically operated worm gear 2, and the electrically operated locking rod 4 has a limiting locking part 41. In the locked position, at least a portion of the limiting locking part 41 extends out of the mounting cavity 111 to limit and lock the electrically operated worm gear 2.

[0074] Specifically, the electrically operated locking rod 4 can be installed inside the mounting housing 11 and can slide relative to the mounting housing 11. The mounting housing 11 is provided with a movable opening 112, and the movable opening 112 is located at the end of the mounting housing 11 facing the electrically operated worm gear 2. The movable opening 112 is a through hole. The electrically operated locking rod 4 is provided with a limiting locking part 41, and the limiting locking part 41 can pass through the movable opening 112 and thus extend out of the mounting cavity 111 through the movable opening 112.

[0075] Furthermore, when the electric locking lever 4 is in the unlocked position, at least a portion of the limiting locking part 41 is located within the mounting cavity 111, that is, the limiting locking part 41 can be partially located within the mounting cavity 111 and partially located outside the mounting cavity 111. When the electric locking lever 4 is in the locked position, at least a portion of the limiting locking part 41 can extend out of the mounting cavity 111 through the movable opening 112, thereby allowing the limiting locking part 41 to limit and lock the electric worm gear 2, so as to avoid the limiting locking part 41 affecting the normal operation of the electric worm gear 2 and ensure the operational stability of the electric worm gear 2.

[0076] In some embodiments, the limiting locking part 41 is formed with a circumferential limiting surface 412, and the electrically operated worm gear 2 is provided with a circumferential stop surface 21. The circumferential stop surface 21 is adapted to limit and press against the circumferential limiting surface 412 when the electrically operated worm gear 2 rotates to the limit position in the second direction; and the limiting locking part 41 is provided with a bending structure 411, and the electrically operated worm gear 2 is provided with a limiting protrusion 22. The limiting protrusion 22 is adapted to press against the bending structure 411 when the electrically operated worm gear 2 rotates in the second direction to limit the limiting locking part 41 from retracting into the movable opening 112.

[0077] Specifically, the electrically operated locking rod 4 is provided with a limiting locking part 41, which can pass through the movable opening 112. When the electrically operated locking rod 4 is in the locked position, the limiting locking part 41 extends out of the movable opening 112 to limit and lock with the electrically operated worm gear 2. The limiting locking part 41 forms a circumferential limiting surface 412 on the side facing the locking link 3. The electrically operated worm gear 2 is provided with a circumferential stop surface 21. When the electrically operated locking rod 4 is in the locked position and the electrically operated worm gear 2 rotates to the limit position in the second direction, the circumferential stop surface 21 can press against the circumferential limiting surface 412, thereby stopping the electrically operated worm gear 2 from rotating. At this time, the electrically operated worm gear 2 can rotate in the first direction to return to the intermediate position, so that the circumferential stop surface 21 presses against the circumferential limiting surface 412, which can ensure the reliability of the limiting.

[0078] Furthermore, such as Figure 12 and Figures 14-15 As shown, the limiting locking part 41 is also provided with a bending structure 411. The bending structure 411 extends toward the open side of the mounting cavity 111 and can extend outside the mounting cavity 111. The electric opening worm gear 2 is provided with a limiting protrusion 22. When the electric opening locking rod 4 is in the locked position and the electric opening worm gear 2 rotates in the second direction, the limiting protrusion 22 can press against the bending structure 411 extending outside the mounting cavity 111, thereby limiting the limiting locking part 41 to partially retract into the movable opening 112 under the elastic force of the first elastic member 6, so that when the electric opening worm gear 2 rotates to the limit position, the circumferential stop surface 21 can press against the circumferential limiting surface 412, thereby stopping the electric opening worm gear 2 from rotating.

[0079] In some embodiments, a limiting post 113 is provided in the mounting cavity 111, and one end of the first elastic member 6 is sleeved outside the limiting post 113. A mounting groove 42 is formed in the electrically operated locking rod 4, and the mounting groove 42 is open toward the limiting post 113. The other end of the first elastic member 6 extends into the mounting groove 42 and presses against the inner wall of the mounting groove 42.

[0080] Specifically, a limiting post 113 is provided inside the mounting cavity 111, and the limiting post 113 extends toward the side opposite to the electrically operated worm gear 2. One end of the first elastic member 6 can be sleeved on the limiting post 113. The electrically operated locking rod 4 is installed inside the mounting cavity 111 of the mounting housing 11, and a mounting groove 42 is formed inside the electrically operated locking rod 4. Figure 4 As shown, the mounting groove 42 is open towards the limiting post 113. That is, when the electrically operated locking rod 4 is installed in the mounting cavity 111 of the mounting housing 11, the bottom wall of the mounting cavity 111 can contact the mounting groove 42 of the electrically operated locking rod 4, thereby forming a mounting groove 42 that is only open towards the limiting locking part 41. The other end of the first elastic member 6 can extend from the opening into the mounting groove 42 to press against the inner wall of the electrically operated locking rod 4, so that the mounting groove 42 can limit the first elastic member 6, avoid the first elastic member 6 from being deflected due to force, and ensure the operational stability of the electrically operated locking rod 4.

[0081] Furthermore, the other end of the first elastic member 6 extends into the mounting groove 42 and presses against the inner wall of the mounting groove 42, so that when the electric locking rod 4 moves toward the electric worm gear 2, it can compress the first elastic member 6, thereby allowing the first elastic member 6 to apply elastic force to the electric locking rod 4, so that the electric locking rod 4 moves from the locked position to the unlocked position. Sleeving the first elastic member 6 outside the limiting post 113 can ensure the reliability of the operation of the first elastic member 6.

[0082] In some embodiments, one of the mounting housing 11 and the electrically unlocking locking rod 4 is provided with a sliding protrusion 43 and the other is provided with a sliding guide groove 114. The sliding protrusion 43 can slide into the sliding guide groove 114 so that the mounting housing 11 and the electrically unlocking locking rod 4 slide into each other.

[0083] Specifically, one of the mounting housing 11 and the electrically unlocking locking rod 4 is provided with a sliding protrusion 43 and the other is provided with a sliding guide groove 114. That is, the sliding protrusion 43 can be provided on the mounting housing 11 or on the electrically unlocking locking rod 4, and the sliding guide groove 114 can be provided on the mounting housing 11 or on the electrically unlocking locking rod 4. In actual use, the sliding protrusion 43 can be provided on the mounting housing 11 and the sliding guide groove 114 can be provided on the electrically unlocking locking rod 4, or the sliding guide groove 114 can be provided on the mounting housing 11 and the sliding protrusion 43 can be provided on the electrically unlocking locking rod 4. In this embodiment, as shown... Figures 2-4 As shown, the sliding guide groove 114 is provided on the mounting housing 11, and the sliding protrusion 43 is provided on the electrically unlocking locking rod 4.

[0084] Furthermore, the sliding protrusion 43 can extend into the sliding guide groove 114, and the sliding protrusion 43 can slide relative to the sliding guide groove 114. When the electrically unlocking locking rod 4 is installed in the mounting housing 11, the sliding protrusion 43 can extend into the sliding guide groove 114, thereby allowing the electrically unlocking locking rod 4 and the mounting housing 11 to slide together. When the electrically unlocking locking rod 4 is subjected to the force of the locking link 3, causing the electrically unlocking locking rod 4 to slide relative to the mounting housing 11, and when the electrically unlocking locking rod 4 is subjected to the elastic force of the first elastic member 6 and slides relative to the mounting housing 11, the sliding protrusion 43 can move along the sliding guide groove 114, thereby limiting the electrically unlocking locking rod 4 and ensuring the operational reliability of the electrically unlocking locking rod 4.

[0085] In some embodiments, there are multiple sliding protrusions 43 that are spaced apart and distributed on two opposite sides of the electrically operated locking rod 4, and there are multiple sliding guide grooves 114 that are provided in a one-to-one correspondence with the multiple sliding protrusions 43.

[0086] Specifically, a sliding guide groove 114 is disposed on the mounting housing 11, and a sliding protrusion 43 is disposed on the electrically unlocking locking rod 4. When the electrically unlocking locking rod 4 is installed in the mounting cavity 111 of the mounting housing 11, the sliding protrusion 43 can extend into the sliding guide groove 114, and the sliding protrusion 43 can slide relative to the sliding guide groove 114, thereby limiting the position of the electrically unlocking locking rod 4. Figures 3-4 As shown, multiple sliding protrusions 43 are provided, and the multiple sliding protrusions 43 are respectively opened at intervals on two opposite sides of the electrically operated locking rod 4. At the same time, multiple sliding guide grooves 114 are also provided, and the multiple sliding guide grooves 114 are also opened at intervals on two sides of the mounting housing 11. The multiple sliding protrusions 43 and the multiple sliding guide grooves 114 are provided in a one-to-one correspondence.

[0087] When the electrically unlocking locking rod 4 moves relative to the mounting housing 11, the sliding guide groove 114 limits the sliding protrusion 43, thereby causing the sliding protrusion 43 to be subjected to force. Setting multiple sliding protrusions 43 allows the force to be applied to multiple sliding protrusions 43 respectively, avoiding the situation where a single sliding protrusion 43 is subjected to excessive force and breaks. In this embodiment, four sliding protrusions 43 are provided, and the four sliding protrusions 43 are symmetrically arranged at intervals on two opposite sides of the electrically unlocking locking rod 4, so that the sliding protrusions 43 on the two opposite sides of the electrically unlocking locking rod 4 are subjected to the same force, avoiding deformation caused by uneven force and extending service life.

[0088] In some embodiments, the locking link 3 is provided with a movable groove 31, and the electrically unlocking locking rod 4 is provided with a pushing protrusion 44. The pushing protrusion 44 extends into the movable groove 31, and a first inner end face 311 and a second inner end face 312 are formed in the movable groove 31. The locking link 3 is adapted to push the pushing protrusion 44 through the first inner end face 311 of the movable groove 31 to drive the electrically unlocking locking rod 4 to move to the locking position.

[0089] Specifically, the locking link 3 is provided with a movable groove 31, and the electrically operated locking rod 4 is provided with a pushing protrusion 44. The pushing protrusion 44 can extend into the movable groove 31, and a first inner end face 311 and a second inner end face 312 are formed in the movable groove 31. The first inner end face 311 and the second inner end face 312 are distributed opposite to each other. When the locking link 3 moves, the pushing protrusion 44 can press against the first inner end face 311 of the movable groove 31, so that the first inner end face 311 can push against the pushing protrusion 44. Applying a force causes the first inner end face 311 to push the push protrusion 44, which in turn causes the electrically unlocking locking rod 4 to slide relative to the mounting cavity 111, allowing the electrically unlocking locking rod 4 to move to the locked position. When the electrically unlocking locking rod 4 is subjected to the elastic force of the first elastic element 6 and switches from the locked position to the unlocked position, the push protrusion 44 can move from the second inner end face 312 to the first inner end face 311, thereby realizing the switching of the position of the electrically unlocking locking rod 4. The structure is simple and highly reliable.

[0090] In some embodiments, the sliding direction of the electric unlocking locking lever 4 relative to the door lock housing 1 is the same as the extending direction of the movable groove 31.

[0091] Specifically, the locking link 3 is provided with a movable groove 31, and the electrically unlocking locking rod 4 is provided with a pushing protrusion 44. The pushing protrusion 44 can extend into the movable groove 31, and when the locking link 3 moves, the pushing protrusion 44 can press against the first inner end face 311 of the movable groove 31, thereby allowing the first inner end face 311 to apply a force to the pushing protrusion 44, causing the electrically unlocking locking rod 4 to slide relative to the mounting cavity 111. When the electrically unlocking locking rod 4 is subjected to the elastic force of the first elastic member 6, it moves from the locked position. When the switch is to the unlock position, the push protrusion 44 can move from the second inner end face 312 to the first inner end face 311. The electric unlocking locking rod 4 is disposed in the mounting shell portion 11 of the door lock housing 1, and the push protrusion 44 of the electric unlocking locking rod 4 extends into the movable groove 31. The sliding direction of the electric unlocking locking rod 4 relative to the door lock housing 1 is set to be the same as the extension direction of the movable groove 31, so that the electric unlocking locking rod 4 and the locking linkage 3 can move in the same direction, ensuring the reliability of the operation of the electric unlocking locking rod 4.

[0092] In some embodiments, the push protrusion 44 is configured to have a cutout 441.

[0093] Specifically, such as Figure 4As shown, the electrically operated locking rod 4 is provided with a pushing protrusion 44, and the pushing protrusion 44 is provided with a hollow hole 441. When the electrically operated worm gear 2 pushes the locking link 3 from the unlocked state to the locked state, the electrically operated locking rod 4 can limit and lock the electrically operated worm gear 2, so that the electrically operated worm gear 2 rotates to the limit position in the second direction. At this time, the locking link 3 has completed the state switching. The pushing protrusion 44 abuts against the second inner end face 312 of the locking link 3, and then the electrically operated worm gear 2 returns to the middle position. Under the action of the elastic force of the first elastic element 6, the electrically operated locking rod 4 slides away from the electrically operated worm gear 2 until the pushing protrusion 44 abuts against the first inner end face 311 of the locking link 3. When the pushing protrusion 44 abuts against the first inner end face 311 of the locking link 3, the hollow hole 441 provided in the middle of the pushing protrusion 44 can play a buffering role, reduce the noise generated by the collision, and improve the comfort of use.

[0094] The hollow hole 441 is located at the center of the push protrusion 44 and is concentric with the push protrusion 44, so that the wall thickness of the push protrusion 44 is the same, thereby ensuring that the structural strength of each surface of the push protrusion 44 is the same, avoiding deformation of the push protrusion 44 due to the force, and extending the service life of the electric unlocking locking rod 4. In addition, the push protrusion 44 is set as a rectangular body with rounded corners, which can concentrate stress at the variable edge and avoid damage to the locking link 3 when it is pressed against the locking link 3, thus extending the service life of the locking link 3.

[0095] In some embodiments, the electrically operated worm gear 2 is provided with a drive protrusion 23, and the locking link 3 is provided with a push groove 32. The drive protrusion 23 extends into the push groove 32, and a first push surface 321 and a second push surface 322 are formed in the push groove 32. The electrically operated worm gear 2 is configured such that when it rotates in a first direction, the drive protrusion 23 presses against the first push surface 321, and when it rotates in a second direction, the drive protrusion 23 presses against the second push surface 322.

[0096] Specifically, the locking link 3 is provided with a push groove 32, and the electrically operated worm gear 2 is provided with a drive protrusion 23. The drive protrusion 23 can be placed in the push groove 32, thereby allowing the electrically operated worm gear 2 to push the locking link 3 to move through the drive protrusion 23. Figure 9 As shown, the push groove 32 is constructed as a groove with one side open, and the groove is open towards the electric worm gear 2. The drive protrusion 23 protrudes from one side, so that the drive protrusion 23 of the electric worm gear 2 can push the locking link 3 to move by pressing against the inner wall of the push groove 32.

[0097] Furthermore, a first pushing surface 321 and a second pushing surface 322 are formed in the pushing groove 32, and the driving protrusion 23 of the electrically operated worm gear 2 can press against the first pushing surface 321 or the second pushing surface 322 to push the locking linkage 3 to move, and as... Figure 11As shown, when the electrically operated worm gear 2 rotates in the first direction, the drive protrusion 23 can press against the first pushing surface 321, thereby pushing the locking linkage 3 from the locked state to the unlocked state, as shown. Figure 16 As shown, when the electric worm gear 2 rotates in the second direction, the drive protrusion 23 can press against the second push surface 322, thereby pushing the locking linkage 3 to switch from the unlocked state to the locked state. Its structure is simple and can ensure operational reliability.

[0098] The push groove 32 is constructed as a groove with one side open to the electric worm gear 2, and an installation port is formed on the side edge of the push groove 32 facing the locking link 3. The installation port is open to the electric worm gear 2, and the size of the installation port is larger than the size of the drive protrusion 23. The drive protrusion 23 of the electric worm gear 2 can be inserted into the push groove 32 through the installation port. Then, the drive protrusion 23 can press against the first push surface 321 or the second push surface 322 of the push groove 32 when the electric worm gear 2 rotates. The installation port facilitates the installation of the electric worm gear 2 and the locking link 3 and improves the overall flexibility.

[0099] In some embodiments, the door lock assembly 100 further includes a second elastic element 7, which is installed between the electric opening worm gear 2 and the door lock housing 1, and is used to apply a centering elastic force to the electric opening worm gear 2.

[0100] Specifically, the door lock assembly 100 is further provided with a second elastic element 7, which can be a spring or the like. The second elastic element 7 is disposed inside the door lock housing 1 and is coaxially disposed with the electric opening worm gear 2. The second elastic element 7 is installed between the electric opening worm gear 2 and the door lock housing 1. When the second elastic element 7 is compressed, it can generate a reaction force to restore its original shape. When the driving member 8 drives the electric opening worm gear 2 to rotate in the first direction, the electric opening worm gear 2 can push the locking linkage 3 to move. During the rotation of the electric opening worm gear 2, the second elastic element 7 is compressed by the force of the electric opening worm gear 2. After the electric opening worm gear 2 has rotated in the first direction, the second elastic element 7 can apply an elastic force in the second direction to the electric opening worm gear 2, so that the electric opening worm gear 2 can rotate in the second direction and thus reset.

[0101] Furthermore, when the driving component 8 drives the electrically operated worm gear 2 to rotate in the second direction, the electrically operated worm gear 2 can push the locking linkage 3 to move. During the rotation of the electrically operated worm gear 2, the second elastic element 7 is compressed by the force exerted by the electrically operated worm gear 2. After the electrically operated worm gear 2 has completed rotating in the second direction, the second elastic element 7 can apply an elastic force in the first direction to the electrically operated worm gear 2, so that the electrically operated worm gear 2 can rotate in the first direction and then reset. The structure is simple and highly reliable, and the operational stability of the electrically operated worm gear 2 can be guaranteed.

[0102] In some embodiments, the electrically operated rocker arm 5 is provided with an unlocking groove 51, and the electrically operated worm gear 2 is provided with an unlocking protrusion 24. The unlocking protrusion 24 extends into the unlocking groove 51 and is adapted to press against the inner wall of the unlocking groove 51 when the electrically operated worm gear 2 rotates in the second direction to push the electrically operated rocker arm 5 to unlock.

[0103] Specifically, an electrically operated rocker arm 5 is installed inside the door lock housing 1. The electrically operated rocker arm 5 is rotatable relative to the door lock housing 1, and can open the car door when it rotates. When the locking linkage 3 is in the locked state, the electrically operated worm gear 2 rotates in the second direction, thereby pushing the electrically operated rocker arm 5 to rotate, and so on. Figure 18 As shown, the electrically operated rocker arm 5 is provided with an unlocking groove 51, and the electrically operated worm gear 2 is provided with an unlocking protrusion 24. When the electrically operated worm gear 2 rotates in the second direction and presses against the electrically operated rocker arm 5, the unlocking protrusion 24 can extend into the unlocking groove 51, thereby pushing the unlocking groove 51 to move, so as to push the electrically operated rocker arm 5 to move. The unlocking groove 51 can limit the unlocking protrusion 24, preventing the unlocking protrusion 24 from shifting when pushing the electrically operated rocker arm 5 to rotate, thus ensuring the stability of operation. Moreover, the structure and cooperation between the unlocking protrusion 24 and the unlocking groove 51 are simple, which can reduce manufacturing costs.

[0104] In some embodiments, the door lock assembly 100 further includes a drive member 8 and a drive worm gear 9, the output end of the drive member 8 is connected to the drive worm gear 9, and the drive worm gear 9 engages with the electrically operated worm wheel 2 for transmission.

[0105] Specifically, the door lock assembly 100 is equipped with a drive component 8 and a drive worm gear 9, such as Figure 1 and Figures 8-14 As shown, the driving component 8 can be configured as a drive motor, and the driving component 8 is provided with an output shaft 81, which is connected to the drive worm 9. That is, the output end of the driving component 8 is connected to the drive worm 9. The driving component 8 outputs power through the output shaft 81, which can drive the drive worm 9 to rotate. The electric opening worm wheel 2 is disposed inside the door lock housing 1 and can rotate relative to the door lock housing 1. The drive worm 9 meshes with the electric opening worm wheel 2, so that when the output shaft 81 of the driving component 8 drives the drive worm 9 to rotate, the drive worm 9 meshes with the electric opening worm wheel 2 for transmission, which can drive the electric opening worm wheel 2 to rotate.

[0106] Furthermore, when the power output by the drive component 8 rotates in different directions, the drive worm 9 also rotates in different directions. This allows the electrically operated worm gear 2, which meshes with the drive worm 9, to rotate in either the first or second direction. The electrically operated worm gear 2 can drive the locking link 3 to move. Moreover, the direction of movement of the locking link 3 varies depending on the rotation direction of the electrically operated worm gear 2. This allows the locking link 3 to switch between locked and unlocked states. In other words, the state of the locking link 3 can be switched by changing the rotation direction of the power output by the drive component 8. The structure is simple and can improve the reliability of power transmission.

[0107] In this embodiment, the complete operation of the door lock assembly 100 is as follows:

[0108] like Figures 8-9 As shown, the electric unlocking locking rod 4 is in the initial position. At this time, the electric unlocking locking rod 4 is subjected to the pre-tightening limiting force of the first elastic element 6, which makes the pushing protrusion 44 of the electric unlocking locking rod 4 fit together with the first inner end face 311 of the locking link 3, thereby enabling the electric unlocking locking rod 4 to move synchronously when the locking link 3 moves.

[0109] like Figures 10-11 As shown, when the drive unit 8 receives the lock unlock signal, it can rotate through the output shaft 81, which in turn drives the drive worm gear 9 to rotate, causing the electric unlock worm wheel 2 to rotate in the first direction. At this time, the drive protrusion 23 of the electric unlock worm wheel 2 presses against the first pushing surface 321 of the locking link 3, thereby driving the locking link 3 to move. The first inner end surface 311 of the locking link 3 can press against the pushing protrusion 44 of the electric unlock locking rod 4, thereby driving the electric unlock locking rod 4 to slide relative to the mounting housing 11.

[0110] Since the driving force applied by the electric worm gear 2 to the locking link 3 is greater than the elastic force generated by the first elastic element 6, the pushing protrusion 44 of the electric locking rod 4 is always in contact with the first inner end face 311 of the locking link 3 during the sliding process of the electric locking rod 4 in the mounting cavity 111. When the electric worm gear 2 rotates to the preset limit position, the driving protrusion 23 of the electric worm gear 2 will separate from the first pushing surface 321 of the locking link 3. The end of the locking link 3 away from the electric locking rod 4 is connected to a rotating rocker arm, which can continue to drive the locking link 3 to move until the unlocking is completed. At this time, the user can open the car door from inside or outside the car.

[0111] like Figures 12-13 As shown, after unlocking, the electric worm gear 2 will rotate in the second direction under the action of the second elastic element 7, and then return to the middle position. At this time, the locking link 3 is maintained in the unlocked state by the force of the rotating rocker arm.

[0112] like Figures 14-16As shown, after the lock unlocking is completed and the electric worm gear 2 is reset, a locking signal is input to the drive unit 8, and the drive unit 8 starts in reverse. The output shaft 81 rotates, driving the drive worm 9 to rotate, which in turn drives the electric worm gear 2 meshing with it to rotate in the second direction. When the electric worm gear 2 rotates in the second direction to the position where the drive protrusion 23 of the electric worm gear 2 is in critical contact with the second pushing surface 322 of the locking link 3, the limiting protrusion 22 of the electric worm gear 2 and the bending structure 411 of the electric locking rod 4 are engaged. Also at the critical contact position, the electric worm gear 2 continues to rotate in the second direction. At this time, the bent structure 411 of the electric locking rod 4 will be locked with the limiting protrusion 22 of the electric worm gear 2, and the locking link 3 will be pushed to the locked state by the electric worm gear 2. When the electric worm gear 2 continues to rotate in the second direction until the circumferential stop surface 21 of the electric worm gear 2 contacts the circumferential limiting surface 412 of the electric locking rod 4, the electric worm gear 2 is limited, so that the rotation of the electric worm gear 2 in the second direction stops.

[0113] After the electric worm gear 2 is limited by the electric locking rod 4, it will rotate to the middle position along the first direction under the elastic force of the second elastic element 7. When the electric worm gear 2 rotates along the first direction until the limiting protrusion 22 of the electric worm gear 2 separates from the bending structure 411 of the electric locking rod 4, the electric locking rod 4 will slide along the mounting cavity 111 to the unlock position under the elastic force of the first elastic element 6 until the pushing protrusion 44 of the electric locking rod 4 fits together with the first inner end face 311 of the locking link 3. The pushing protrusion 44 is provided with a hollow hole 441. When the pushing protrusion 44 collides with the locking link 3, the hollow hole 441 can play a buffering role, so that the collision kinetic energy is released in a gradient, thereby reducing noise.

[0114] like Figures 17-18 As shown, when the electric locking lever 4 is switched to the unlocked position and the locking linkage 3 is in the unlocked state, after the limiting protrusion 22 of the electric unlocking worm gear 2 separates from the bending structure 411 of the electric locking lever 4, the electric unlocking worm gear 2 rotates to the middle position in the first direction under the action of the second elastic member 7. At this time, an electrolytic unlocking signal is input to the drive member 8, and the drive member 8 can continue to start in reverse. The output shaft 81 rotates, driving the drive worm gear 9 to rotate, which in turn drives the electric unlocking worm gear 2 meshing with it to rotate in the second direction. At this time, the electric locking lever 4 is in the unlocked position, and the electric unlocking worm gear 2 will rotate in the second direction until the unlocking protrusion 24 of the electric unlocking worm gear 2 presses against the unlocking groove 51 of the electric unlocking rocker arm 5, thereby driving the electric unlocking rocker arm 5 to rotate, and thus realizing the electric unlocking to open the car door.

[0115] The present invention also proposes a vehicle.

[0116] The vehicle according to an embodiment of the present invention is provided with a door lock assembly 100 as described above.

[0117] According to an embodiment of the present invention, the vehicle is provided with a door lock assembly 100, and the door lock assembly 100 is slidably connected to the electric unlocking locking rod 4 via the locking link 3, thereby reducing the volume of the door lock assembly 100, reducing the installation space required for the door lock assembly 100, improving vehicle lightweighting, reducing installation costs, improving performance, and expanding applicability.
