[0031] Reference below Figure 1-Figure 4 The door lock assembly according to the embodiment of the utility model is described, which has a simple structure, saves space and improves lightness.

[0032] like Figure 1-Figure 4 As shown, the door lock assembly according to the embodiment of the utility model includes a swing arm 2 and a central locking mechanism 3. The central locking mechanism 3 has an upper central locking state and an unlocked central locking state.

[0034] The vehicle door lock is an important component to ensure the safety of the vehicle. The structural principle of the vehicle door lock directly affects the convenience and safety of the vehicle. The vehicle door lock drives the locking arm to move to open the door. During use, in order to avoid accidental opening of the door due to accidental touching of the door lock, a central locking mechanism 3 can be set. When the central locking mechanism 3 is in the upper central locking state, the locking arm of the door cannot be rotated, thereby improving the safety of use.

[0035] Specifically, the door lock assembly is provided with an inner opening mechanism and an outer opening mechanism, and the door lock assembly is also provided with a swing arm 2, which is arranged inside the door lock housing 1 and is movable relative to the door lock housing 1. Both the inner opening mechanism and the outer opening mechanism can cooperate with the swing arm 2 to open the vehicle door, that is, the inner opening mechanism or the outer opening mechanism can move to contact with the swing arm 2, thereby pushing the swing arm 2 to move relative to the door lock housing 1, so that the swing arm 2 can drive the locking arm to move to open the vehicle door, and the outer opening mechanism is provided with a locked state and an unlocked state. When the outer opening mechanism is in the locked state, the outer opening mechanism does not contact with the swing arm 2 when it moves relative to the door lock housing 1, and when the outer opening mechanism is in the unlocked state, the outer opening mechanism can contact with the swing arm 2 when it moves relative to the door lock housing 1, thereby pushing the swing arm 2 to move relative to the door lock housing 1, and the swing arm 2 can drive the locking arm to move to open the vehicle door, thereby improving the safety of use.

[0036] Furthermore, the door lock assembly is provided with a central locking mechanism 3, and the central locking mechanism 3 is provided with an upper central locking state and an unlocked central locking state. When the central locking mechanism 3 is in the upper central locking state, the outer opening mechanism can be in a locked state, and when the central locking mechanism 3 is in the unlocked central locking state, the outer opening mechanism can be in an unlocked state, and when the central locking mechanism 3 is in the unlocked central locking state, the swing arm 2 can be driven by the inner opening mechanism or the outer opening mechanism to drive the locking arm to move so that the vehicle door is unlocked. The central locking mechanism 3 is provided with a driving member 31 and a central control worm gear 32. The driving member 31 is provided with a driving motor 311 and a driving worm 312. The output end of the driving member 31 is power-connected to the central control worm gear 32 That is, the driving member 31 is movably connected to the central control worm gear 32 and can output power to the central control worm gear 32. The driving motor 311 is provided with a motor shaft 3111. The motor shaft 3111 is connected to the driving worm 312. The driving motor 311 outputs power through the motor shaft 3111, thereby driving the driving worm 312 to rotate. The central control worm gear 32 is arranged in the door lock housing 1. The door lock housing 1 is provided with a mounting column. The central control worm gear 32 is rotatably connected to the door lock housing 1 through the mounting column, and the driving worm 312 is meshed with the central control worm gear 32, thereby making it possible for the driving motor 311 to drive the driving worm 312 to rotate, and the driving worm 312 can drive the central control worm gear 32 to rotate.

[0037] The central locking mechanism 3 is also provided with a locking link 33, which is movable relative to the door lock housing 1, and the central control worm gear 32 is movably connected to the locking link 33. The central control worm gear 32 can rotate relative to the door lock housing 1 under the action of the driving worm 312. During the rotation, the central control worm gear 32 can push the locking link 33 to move relative to the door lock housing 1, and during the movement of the locking link 33, the central locking mechanism 3 can be driven to switch between the upper central locking state and the unlocked central locking state. When the central locking mechanism 3 is in the upper central locking state, the inner opening mechanism or the outer opening mechanism cannot push the swing arm 2 to drive the locking arm to move to unlock the vehicle door. When the central locking mechanism 3 is in the unlocked central locking state, the inner opening mechanism or the outer opening mechanism can push the swing arm 2 to drive the locking arm to move to unlock the vehicle door. It has a simple structure, occupies a small space and has high reliability.

[0038] According to the door lock assembly of the embodiment of the utility model, the central control worm gear 32 pushes the locking link 33 to move when rotating, so that the central control lock mechanism 3 can be switched between the upper central control lock state and the unlocked central control lock state. It has a simple structure, can save space in the door lock housing 1, improve the lightweight of the vehicle, have better use effect, and have a wider range of applications.

[0039] In some embodiments, when the central control worm gear 32 rotates in a first direction, it pushes the locking link 33 to move so that the central control locking mechanism 3 switches from the upper central control locking state to the unlocked central control locking state, and when it rotates in a second direction, it pushes the locking link 33 to move so that the central control locking mechanism 3 switches from the unlocked central control locking state to the upper central control locking state. The first direction is opposite to the second direction.

[0040] Specifically, the driving worm 312 is meshed with the central control worm wheel 32 to drive the central control worm wheel 32 to rotate relative to the door lock housing 1, and when the motor rotates in different directions, the direction of its output power is also different, thereby causing the driving worm 312 to rotate in different directions. The driving worm 312 drives the central control worm wheel 32 to rotate, and the different rotation directions of the driving worm 312 cause the central control worm wheel 32 to rotate in different directions.

[0041] Furthermore, the central control worm gear 32 can drive the locking link 33 to move. When the rotation direction of the central control worm gear 32 is different, the direction in which the locking link 33 is driven to move is also different, thereby making the effect of the locking link 33 on the locking assembly different. When the central control worm gear 32 rotates along a first direction, the central control worm gear 32 can push the locking link 33 to move, thereby driving the central control lock mechanism 3 to switch from the upper central control lock state to the unlocked central control lock state. When the central control worm gear 32 rotates along a second direction, the central control worm gear 32 can push the locking link 33 to move, thereby driving the central control lock mechanism 3 to switch from the unlocked central control lock state to the upper central control lock state, and the first direction is opposite to the second direction, that is, the rotation direction of the central control worm gear 32 is opposite, so that the locking link 33 moves in the opposite direction, which can avoid errors during the driving process and ensure the reliability of the locking assembly state.

[0042] Among them, one of the first direction and the second direction can be set to the clockwise direction, and the other can be set to the counterclockwise direction, that is, the first direction can be set to the clockwise direction and the second direction can be set to the counterclockwise direction, or the first direction can be set to the counterclockwise direction and the second direction can be set to the clockwise direction. In this embodiment, the first direction refers to the clockwise direction and the second direction refers to the counterclockwise direction.

[0043] In some embodiments, the central control worm gear 32 is provided with a first pushing portion 321, and the locking link 33 is provided with a movable groove 331. The first pushing portion 321 can be movably extended into the movable groove 331. When the central control worm gear 32 rotates along a first direction, the first pushing portion 321 is suitable for pressing against one end in the movable groove 331. When the central control worm gear 32 rotates along a second direction, the first pushing portion 321 is suitable for pressing against the other end in the movable groove 331.

[0044] Specifically, the central control worm gear 32 can rotate along the first direction or the second direction under the drive of the driving member 31, and the central control worm gear 32 can drive the locking link 33 to move during the rotation process. Figure 4 As shown, the central control worm gear 32 is provided with a first pushing portion 321, and the locking link 33 is provided with a movable groove 331. The first pushing portion 321 can be set as a pushing column, a pushing plate, etc. The first pushing portion 321 can extend into the movable groove 331, and the first pushing portion 321 can be movable in the movable groove 331 relative to the inner wall of the movable groove 331, so that when the central control worm gear 32 rotates along the first direction or the second direction, its first pushing portion 321 can also move relatively in the movable groove 331.

[0045] Furthermore, when the central control worm gear 32 rotates along the first direction, the first pushing portion 321 of the central control worm gear 32 can move in the movable groove 331, and can move to one end in the movable groove 331, and then press against the inner wall of one end of the movable groove 331 to push the locking link 33 to move. When the central control worm gear 32 rotates along the second direction, that is, the central control worm gear 32 rotates in the opposite direction, the first pushing portion 321 of the central control worm gear 32 can move in the movable groove 331, and can move to the other end in the movable groove 331, and then press against the inner wall of the other end of the movable groove 331 to push the locking link 33 to move in the opposite direction, and then the central control locking mechanism 3 can be switched between the upper central control locking state and the unlocked central control locking state through the locking link 33, with a simple structure and high reliability.

[0046] In some embodiments, the movable groove 331 is constructed as a groove that is open on the side of the locking link 33 toward the central control worm gear 32, the first pushing portion 321 is constructed as a pressing protrusion that protrudes on the side of the central control worm gear 32 toward the locking link 33, and the movable groove 331 is formed with an installation opening 3311 that is open on the edge of one side of the locking link 33.

[0047] Specifically, the locking link 33 is provided with a movable groove 331, and the central control worm wheel 32 is provided with a first pushing portion 321, and the first pushing portion 321 can be placed in the movable groove 331, so that the central control worm wheel 32 can push the locking link 33 to move through the first pushing portion 321, and Figure 1 As shown, the movable groove 331 is constructed as a groove with one side open, and the groove is open toward the central control worm gear 32, and the first pushing portion 321 is constructed as a pressing protrusion, one side of the pressing protrusion is protruding, and the pressing protrusion is protruding toward the locking link 33, so that the first pushing portion 321 of the central control worm gear 32 can press the inner wall of the movable groove 331, thereby pushing the locking link 33 to move.

[0048] Furthermore, the movable groove 331 is formed with an installation opening 3311 which is open on one side edge of the locking link 33, and the installation opening 3311 is open toward the central control worm gear 32, that is, the movable groove 331 is configured as an open groove body, and its opening is configured as the installation opening 3311, and the installation opening 3311 is formed on one side of the locking link 33, and the installation opening 3311 is open toward the central control worm gear 32, and the size of the installation opening 3311 is larger than the size of the first pushing portion 321, and the first pushing portion 321 of the central control worm gear 32 can be inserted into the movable groove 331 through the installation opening 3311, and then the first pushing portion 321 can press the movable groove 331 when the central control worm gear 32 rotates. The provision of the installation opening 3311 can facilitate the installation of the central control locking mechanism 3 and improve the overall flexibility.

[0049] In some embodiments, the central locking mechanism 3 of the door lock assembly also includes a worm gear reset member 34, which is installed on the central control worm wheel 32. The worm gear reset member 34 is used to apply an elastic force along the second direction to the central control worm wheel 32 after the driving member 31 drives the central control worm wheel 32 to rotate along the first direction, and is used to apply an elastic force along the first direction to the central control worm wheel 32 after the driving member 31 drives the central control worm wheel 32 to rotate along the second direction.

[0050] Specifically, Figure 1 As shown, the central locking mechanism 3 is also provided with a worm gear reset member 34, which can be set as a spring or the like. The worm gear reset member 34 is arranged in the door lock housing 1 and is coaxially arranged with the central control worm gear 32, and the worm gear reset member 34 is installed on the central control worm gear 32. When the worm gear reset member 34 is compressed, it can generate a reaction force in order to restore the original state. When the driving member 31 drives the central control worm gear 32 to rotate along the first direction, the central control worm gear 32 can push the locking link 33 to move, and during the rotation of the central control worm gear 32, the worm gear reset member 34 is compressed by the force of the central control worm gear 32. After the central control worm gear 32 completes the rotation along the first direction, the worm gear reset member 34 can apply an elastic force along the second direction to the central control worm gear 32, so that the central control worm gear 32 can rotate along the second direction and then reset.

[0051] Furthermore, when the driving member 31 drives the central control worm gear 32 to rotate in the second direction, the central control worm gear 32 can push the locking link 33 to move, and during the rotation of the central control worm gear 32, the worm gear reset member 34 is compressed by the force of the central control worm gear 32. After the central control worm gear 32 completes the rotation in the second direction, the worm gear reset member 34 can apply an elastic force in the first direction to the central control worm gear 32, so that the central control worm gear 32 can rotate in the first direction and then reset. The structure is simple and the reliability is high, which can ensure the operating stability of the central control worm gear 32.

[0052] In some embodiments, the worm gear reset member 34 is constructed as a reset torsion spring, and two ends of the reset torsion spring are pressed against the door lock housing 1 and the central control worm gear 32 respectively.

[0053] Specifically, Figure 1 As shown, a worm gear reset member 34 is provided in the door lock housing 1, and the worm gear reset member 34 is installed on the central control worm wheel 32. When the driving member 31 drives the central control worm wheel 32 to rotate, the worm gear reset member 34 can be compressed, and when the central control worm wheel 32 completes the rotation, the worm gear reset member 34 can apply elastic force to the central control worm wheel 32, so that the central control worm wheel 32 is reset. The worm gear reset member 34 is constructed as a reset torsion spring, and the reset torsion spring is coaxially arranged with the central control worm wheel 32. The central control worm wheel 32 is provided with a mounting column 341 for mounting the reset torsion spring. The reset torsion spring is sleeved outside the mounting column 341, and one end of the worm gear reset member 34 can be pressed against the door lock housing 1, and the other end can be pressed against the central control worm gear 32, so that when the central control worm gear 32 rotates, it can apply a force to the worm gear reset member 34, thereby deforming the worm gear reset member 34, and when the central control worm gear 32 does not apply a force to the worm gear reset member 34, the elastic force generated by the worm gear reset member 34 to restore the deformation can drive the central control worm gear 32 to rotate, thereby completing the reset of the central control worm gear 32, the structure is simple, and the setting cost is low.

[0054] In some embodiments, the central control worm gear 32 is further configured to rotate in the second direction to push the swing arm 2 to unlock the door after the central locking mechanism 3 switches from the unlocked central locking state to the upper central locking state.

[0055] Specifically, the driving member 31 can drive the central control worm gear 32 to rotate in the first direction or the second direction, so that the central control worm gear 32 can drive the locking link 33 to move when rotating, and then the locking link 33 can drive the central control lock mechanism 3 to switch between the unlocked central control lock state and the upper central control lock state. When the central control worm gear 32 rotates in the second direction, it can drive the locking link 33 to move, and then the central control lock mechanism 3 can switch from the unlocked central control lock state to the upper central control lock state, and when the central control lock mechanism 3 is in the upper central control lock state, the outer opening mechanism is in a locked state, that is, the swing arm 2 cannot be driven to move by the inner opening mechanism or the outer opening mechanism, thereby driving the locking arm to move to unlock the vehicle door. At this time, the driving member 31 can drive the central control worm gear 32 to continue to rotate in the second direction, so that the central control worm gear 32 can push the swing arm 2 to rotate in the second direction, and then the swing arm 2 can drive the locking arm to move when rotating, so as to open the vehicle door, thereby meeting various door opening requirements.

[0056] In some embodiments, the central control worm gear 32 is further provided with a second pushing portion 322 , the rocking arm 2 is provided with a pressing recess 21 , and the second pushing portion 322 extends to the pressing recess 21 and is suitable for pushing the rocking arm 2 to move.

[0057] Specifically, when the central locking mechanism 3 is in the upper central locking state, the driving member 31 can drive the central control worm gear 32 to rotate in the second direction, thereby driving the swing arm 2 to rotate, so that the swing arm 2 can drive the locking arm to move when rotating to open the door, and Figure 1 As shown, the central control worm gear 32 is provided with a second pushing portion 322, and the second pushing portion 322 can be set as a pushing column, a pushing protrusion, etc., and the rocking arm 2 is provided with a pressing recess 21. When the central control worm gear 32 rotates along the second direction until it presses against the rocking arm 2, the second pushing portion 322 can extend to the pressing recess 21, and then the second pushing portion 322 can push the rocking arm 2 to move. The pressing recess 21 can limit the second pushing portion 322 to avoid displacement of the second pushing portion 322 when pushing the rocking arm 2, thereby ensuring the stability of operation. The structure and coordination of the pressing recess 21 and the second pushing portion 322 are simple, which can reduce the manufacturing cost.

[0058] In some embodiments, the driving member 31 includes a driving motor 311 and a driving worm 312 . The driving worm 312 is connected to a motor shaft 3111 of the driving motor 311 . The driving worm 312 is meshed with the central control worm wheel 32 for transmission.

[0059] Specifically, Figure 1-Figure 4As shown, the central locking mechanism 3 is provided with a driving member 31 and a central control worm gear 32, the driving member 31 is provided with a driving motor 311 and a driving worm 312, the driving motor 311 is provided with a motor shaft 3111, the motor shaft 3111 is connected to the driving worm 312, the driving motor 311 outputs power through the motor shaft 3111, and then can drive the driving worm 312 to rotate, the central control worm gear 32 is arranged in the door lock housing 1, and the door lock housing 1 is provided with a mounting column, and the central control worm gear 32 is connected to the door lock housing 1. It is rotatably connected to the door lock housing 1 through the mounting column, and the driving worm 312 is meshed with the central control worm gear 32, so that when the driving motor 311 drives the driving worm 312 to rotate, the driving worm 312 can drive the central control worm gear 32 to rotate, so that the central control worm gear 32 can push the locking link 33 to move relative to the door lock housing 1, and during the movement of the locking link 33, the central control lock mechanism 3 can be driven to switch between the upper central control lock state and the unlocked central control lock state, thereby meeting different needs.

[0060] In some embodiments, the door lock assembly includes a swing arm 2 and a central locking mechanism 3. The door lock assembly is provided with a swing arm 2, which is arranged inside the door lock housing 1 and is movable relative to the door lock housing 1. The central locking mechanism 3 is suitable for driving the swing arm 2 to move and drive the locking arm to move to unlock the vehicle door through the inner opening mechanism or the outer opening mechanism in the central lock unlocking state. The outer opening mechanism can be set to a pawl and a pawl slider. The pawl is installed inside the door lock housing 1 through a mounting column and is rotatable relative to the door lock housing. The pawl slider is installed inside the door lock housing 1 through a mounting column. The pawl slider is rotatable relative to the door lock housing and slidable relative to the pawl. The locking link 33 can move to press against the pawl slider so that the pawl slider slides relative to the pawl.

[0061] The pawl slider has a locking position and an unlocking position relative to the pawl. When the pawl slider slides to the unlocking position relative to the pawl, the pawl can drive the pawl slider to push the swing arm 2 to move, and then drive the locking arm to move to unlock the door. At this time, the central locking mechanism 3 is in the unlocked central locking state, and when the pawl slider slides to the locked position relative to the pawl, the pawl drives the pawl slider to rotate, but the rotation trajectory of the pawl slider is staggered with the swing arm 2, and cannot push the swing arm 2 to move, and then cannot drive the locking arm to move. At this time, the central locking mechanism 3 is in the upper central locking state.

[0062] Furthermore, the central locking mechanism and the swing arm 2 can cooperate with each other to open the vehicle door, that is, when the central locking mechanism 3 is in the unlocked central locking state, the inner opening mechanism or the outer opening mechanism can drive the swing arm 2 to move and drive the locking arm to move, thereby opening the vehicle door, and when the central locking mechanism 3 is in the upper central locking state, the inner opening mechanism or the outer opening mechanism does not contact the swing arm 2. At this time, the central locking mechanism 3 can directly drive the swing arm 2 to move and drive the locking arm to move to open the vehicle door, which can improve safety in use.

[0063] The utility model also provides a vehicle.
