[0009] An outward-opening pull rod is mounted on the bottom of the housing, the outward-opening pull rod having a long slot parallel to the bottom of the housing, a transition pull rod is disposed in the long slot, the transition pull rod slides along the long slot, and the sliding direction is a direction away from or close to the pawl; the transition pull rod has a stop portion;

[0010] An electric safety gear mounted on the bottom of the housing;

[0011] The electric safety gear is forced to rotate counterclockwise and apply force to the resisting part, causing the transition pull rod to rotate clockwise and causing the engaging protrusion on the transition pull rod to disengage from the engaging recess on the pawl release rod, thereby achieving safety. At this time, when the inner opening mechanism and the outer opening pull rod are toggled to cause the transition pull rod to slide along the long slot toward the direction away from the pawl, the pawl release rod and the pawl are not subject to force and cannot be unlocked; the electric safety gear is forced to rotate clockwise, releasing the force applied to the resisting part, and the transition pull rod rotates counterclockwise under the action of the reset spring, causing the engaging protrusion on the transition pull rod to engage with the engaging recess on the pawl release rod, thereby achieving safety release. At this time, when the inner opening mechanism and the outer opening pull rod are toggled to cause the transition pull rod to slide along the long slot toward the direction away from the pawl, the pawl release rod and the pawl are driven by the transition pull rod to achieve unlocking.

[0012] Optionally, in the novel automobile door lock device, the inner opening mechanism includes: an inner opening pull rod, a rotating shaft and an inner opening pull rod return spring;

[0013] The inner opening pull rod is installed on the side wall of the shell through a rotating shaft, the inner opening pull rod reset spring is installed on the rotating shaft, and the inner opening pull rod is provided with a hook.

[0014] Optionally, in the new automobile door lock device, the inner opening pull rod also has a first shift block. After the inner opening pull rod is connected to a pull wire, the pull wire causes the inner opening pull rod to rotate clockwise, and the first shift block drives the transition pull rod to slide along the long slot in the direction away from the pawl.

[0015] Optionally, in the novel automobile door lock device,

[0016] An outward-opening pull rod rivet passes through the outward-opening pull rod, the first hole axis of the bottom of the shell and a metal bottom plate, and fixes the outward-opening pull rod, the bottom of the shell and the metal bottom plate. The order from top to bottom is the outward-opening pull rod, the bottom of the shell and the metal bottom plate. An outward-opening pull rod return spring is installed on the outward-opening pull rod rivet;

[0017] After the outward-opening pull rod is connected to the pull wire, the pull wire and the long slot are respectively located on both sides of the outward-opening pull rod rivet. The pull wire causes the outward-opening pull rod to rotate counterclockwise and drives the transition pull rod to slide along the long slot toward away from the pawl.

[0018] Optionally, in the novel automobile door lock device,

[0019] The pawl and the pawl release lever are both mounted on the bottom of the housing via pawl rivets and are reset by a pawl spring;

[0020] The lock tongue is mounted on the bottom of the housing through a lock tongue rivet and is reset by a lock tongue spring.

[0022] When in the safety state, the pull wire causes the inner opening pull rod to rotate clockwise, and the bent hook of the inner opening pull rod drives the toggle component to rotate counterclockwise, and the toggle component drives the electric safety gear to rotate clockwise. The electric safety gear releases the force applied to the resisting part, and the transition pull rod rotates counterclockwise under the action of the reset spring, causing the engaging protrusion on the transition pull rod to engage with the engaging concave block on the pawl release rod, thereby completing the safety release.

[0023] Optionally, the novel automobile door lock device further includes a drive unit and an external locking lever;

[0024] The driving unit is arranged at the bottom of the housing and includes a worm and a motor. The motor provides positive and negative forces to the worm. The driving unit is linked to the electric safety gear in a gear manner.

[0025] The outer locking lever is axially arranged at the bottom of the housing through a second hole at the bottom of the housing and is fixed by a back plate, the back plate being parallel to the bottom of the housing. The outer locking lever includes a first end and a second end, which are respectively located on both sides of the outer locking lever rivet. The first end extends out of the housing, and the second end has a protrusion that penetrates into the electric safety gear.

[0026] The driving unit, the external locking lever or the toggle member drives the electric safety gear to rotate counterclockwise to implement the safety;

[0027] The driving unit, the outer locking lever or the toggle member drives the electric safety gear to rotate clockwise to release the safety.

[0028] Optionally, the novel automobile door lock device further includes a child safety mechanism disposed on a side wall of the housing, the child safety mechanism including a child safety dial button, a child safety connecting rod, and an inward-opening transition rod, the inward-opening transition rod and the inward-opening pull rod rotate coaxially, the inward-opening transition rod having a third hole axis, the child safety connecting rod rotating along the third hole axis under the control of the child safety dial button; the inward-opening transition rod having a second dial block, and the child safety connecting rod having a limiting protrusion;

[0029] When the child safety dial button is toggled, the child safety connecting rod is triggered to rotate along the third hole axis, so that the limiting protrusion moves to the first state position. The limiting protrusion in the first state position forms a linkage relationship between the inner opening transition rod and the inner opening pull rod, thereby releasing the child safety. When the inner opening pull rod is toggled, the second dial block on the inner opening transition rod toggles the transition pull rod to slide along the long slot in a direction away from the ratchet.

[0030] Resetting the child safety dial button triggers the child safety connecting rod to rotate along the third hole axis, causing the limiting protrusion to move to the second state position. The limiting protrusion in the second state position cancels the linkage relationship between the inner opening transition rod and the inner opening pull rod, thereby realizing child safety. When the inner opening pull rod is toggled, the inner opening transition rod does not move.

[0031] Optionally, in the novel automobile door lock device, a door light cam is provided on the lock tongue, and the door light cam rotates synchronously with the lock tongue.

[0043] In the prior art, the unlocking and locking of the automobile door lock are achieved by the cooperation of a lock tongue and a pawl. As long as there is a corresponding key, the locking and unlocking functions of the door lock can be achieved. The function is single and cannot meet the needs of users.

[0044] In order to solve the problems existing in the prior art, the present invention provides a new type of automobile door lock device, such as Figure 1-6b As shown, the device includes:

[0045] Shell 023;

[0046] A pawl 028 and a lock tongue 029 are mounted on the bottom of the housing 023. When the pawl 028 and the lock tongue 029 engage, the car door lock is locked. When the pawl 028 and the lock tongue 029 disengage, the car door lock is unlocked. A pawl release lever 09 is provided on the pawl 028, and the pawl 028 and the pawl release lever 09 rotate synchronously. The pawl 028 and the pawl release lever 09 are both mounted on the bottom of the housing 023 via a pawl rivet 031. They are reset by a pawl spring 012 and are buffered by a pawl buffer block 025 to prevent damage to components due to excessive reset speed. The lock tongue 029 is mounted on the bottom of the housing 023 via a lock tongue rivet 026. It is reset by a lock tongue spring and is buffered by a lock tongue buffer block 024 to prevent damage to components due to excessive reset speed.

[0047] The inner opening mechanism 22 is installed on the side wall of the shell 023, and the inner opening mechanism 22 includes: an inner opening pull rod 43, a rotating shaft and an inner opening pull rod reset spring 021. The inner opening pull rod 43 is installed on the side wall of the shell 023 through the rotating shaft, and the inner opening pull rod reset spring 021 is installed on the rotating shaft. The inner opening pull rod 43 has a bent hook.

[0048] An outward-opening pull rod 08 is installed at the bottom of the shell 023, and an outward-opening pull rod rivet 06 passes through the outward-opening pull rod 08, the first hole axis at the bottom of the shell 023 and a metal bottom plate 030, and fixes the outward-opening pull rod 08, the bottom of the shell 023 and the metal bottom plate 030. The order from top to bottom is the outward-opening pull rod 08, the bottom of the shell 023 and the metal bottom plate 030. An outward-opening pull rod return spring 016 is installed on the outward-opening pull rod rivet 06; the outward-opening pull rod 08 also has a 3. A long groove parallel to the bottom, in which a transition rod 03 is arranged. The transition rod 03 slides along the long groove in a direction away from or toward the pawl 028. The transition rod 03 is reset by a transition rod reset spring 010. That is, the transition rod 03 moves away from the pawl 028 under the triggering of the inner opening mechanism 22 and the outer opening rod 08 to unlock, and moves toward the pawl 028 under the action of the transition rod reset spring 010 to reset;

[0049] The transition rod 03 has a resisting portion 32;

[0050] An electric safety gear 02 is mounted on the bottom of the housing 023; the electric safety gear 02 is mounted on the bottom of the housing 023 via a rotating shaft, is reset by a gear reset spring 015, and is damped by an eccentric spring 011;

[0051] The electric safety gear 02 is forced to rotate counterclockwise and exert force on the resisting portion 32, causing the transition pull rod 03 to rotate clockwise and causing the engaging protrusion 33 on the transition pull rod 03 to disengage from the engaging recess 34 on the pawl release rod 09, thereby achieving safety. At this time, when the inner opening mechanism 22 and the outer opening pull rod 08 are toggled to cause the transition pull rod 03 to slide along the long slot toward the direction away from the pawl 028, the pawl release rod 09 and the pawl 028 are not subjected to force and cannot be unlocked; the electric safety gear 02 is forced to rotate clockwise to release the force applied to the resisting portion 32, and the transition rod 03 rotates counterclockwise under the action of the reset spring, causing the engaging protrusion 33 on the transition rod 03 to engage with the engaging recess 34 on the pawl release rod 09 to release the safety. At this time, when the inner opening mechanism 22 and the outer opening rod 08 are pushed to cause the transition rod 03 to slide along the long slot toward and away from the pawl 028, the pawl release rod 09 and the pawl 028 are driven by the transition rod 03 to unlock.

[0052] Furthermore, the inner opening pull rod 43 also has a first shift block. After the inner opening pull rod 43 is connected to a pull wire, the pull wire prompts the inner opening pull rod 43 to rotate clockwise, and the first shift block prompts the transition pull rod 03 to slide along the long slot in the direction away from the pawl 028. Preferably, the inner opening pull rod 43 can be unlocked by a single pull or double pull. After the outer opening pull rod 08 is connected to a pull wire, the pull wire and the long slot are respectively located on both sides of the outer opening pull rod rivet 06. The pull wire prompts the outer opening pull rod 08 to rotate counterclockwise and drives the transition pull rod 03 to slide along the long slot in the direction away from the pawl 028. Preferably, the outer opening pull rod 08 can be connected to either a pull wire or a connecting rod. Furthermore, a keyhole can be provided at the outer opening pull rod 08 to lock or unlock with a key.

[0053] Optionally, the new automobile door lock device 1 also includes: a toggle member 020, which is installed on the side wall of the shell 023 through a rotating shaft, and the toggle member 020 is linked to the inner opening pull rod 43 in a gear manner, and the toggle member 020 is linked to the electric safety gear 02 in a gear manner.

[0054] When the safety is on, the pull wire causes the inner opening lever 43 to rotate clockwise, and the hook of the inner opening lever 43 drives the toggle member 020 to rotate counterclockwise. The toggle member 020 drives the electric safety gear 02 to rotate clockwise, and the electric safety gear 02 releases the force applied to the resisting portion 32. The transition lever 03 rotates counterclockwise under the action of the return spring, causing the engaging protrusion 33 on the transition lever 03 to engage with the engaging recess 34 on the pawl release lever 09, completing the safety release. Then, the pull wire releases the inner opening lever 43, and the inner opening lever 43 is reset under the action of the inner opening lever return spring 021. The pull wire again causes the inner opening lever 43 to rotate clockwise, and the first toggle block on the inner opening lever 43 drives the transition lever 03 to slide along the long slot in the direction away from the pawl 028. The pawl release lever 09 and the pawl 028 are driven by the transition lever 03 to achieve unlocking. It can be seen that when the insurance is on, the car can be unlocked by pulling the inner opening lever 43 twice in the car, thereby avoiding the danger of people being locked in the car.

[0055] Furthermore, in addition to the method of releasing the safety by opening the inner pull rod 43, the safety can also be applied and released by the drive unit and the outer locking lever 013, so the device also includes a drive unit and an outer locking lever 013; the drive unit is arranged on the bottom of the shell 023, and includes a worm 04 and a motor 05, and the motor 05 provides forward and reverse forces to the worm 04, and the drive unit is linked to the electric safety gear 02 in a gear manner; the outer locking lever 013 is arranged on the bottom of the shell 023 through the second hole axis at the bottom of the shell 023, and is fixed by a back plate 07, and the back plate 07 is parallel to the bottom of the shell 023, and the outer locking lever 013 includes a first end and a second end. The two ends are respectively located on both sides of the outer locking lever rivet, the first end extends out of the shell 023, and the second end has a protrusion that penetrates into the electric safety gear 02; the driving unit (controlled by the motor control unit 014), the outer locking lever 013 (manually controlled outside the vehicle) or the toggle component 020 (the inner opening pull rod 43 rotates counterclockwise) drives the electric safety gear 02 to rotate counterclockwise to implement the safety; the driving unit (controlled by the motor control unit 014), the outer locking lever 013 (manually controlled outside the vehicle) or the toggle component 020 (the inner opening pull rod 43 rotates clockwise) drives the electric safety gear 02 to rotate clockwise to implement the safety.

[0056] Preferably, the device further comprises a child safety mechanism provided on the side wall of the housing 023, the child safety mechanism comprising a child safety dial button 40, a child safety connecting rod 41 and an inward-opening transition rod 42, the inward-opening transition rod 42 and the inward-opening pull rod 43 coaxially rotating, the inward-opening transition rod 42 having a third hole axis, the child safety connecting rod 41 rotating along the third hole axis under the control of the child safety dial button 40; the inward-opening transition rod 42 having a second dial block, the child safety connecting rod 41 having a limiting protrusion;

[0057] Toggle the child protection dial button 40 to trigger the child protection connecting rod 41 to rotate along the third hole axis, so that the limiting protrusion moves to the first state position. The first state position is referenced Figure 1 In the middle phantom position, the limiting protrusion in the first state position forms a linkage relationship between the inner opening transition rod 42 and the inner opening pull rod 43 to release the child safety. When the inner opening pull rod 43 is turned, the second shifting block on the inner opening transition rod 42 shifts the transition pull rod 03 to slide along the long slot in the direction away from the pawl 028;

[0058] Reset the child protection dial button 40, trigger the child protection connecting rod 41 to rotate along the third hole axis, so that the limiting protrusion moves to the second state position, the second state position refers to Figure 1 In the middle physical position, the limiting protrusion located in the second state position cancels the linkage relationship between the inner opening transition rod 42 and the inner opening pull rod 43, thereby realizing the child safety. When the inner opening pull rod 43 is turned, the inner opening transition rod 42 does not move.

The novel automobile door lock device according to claim 1, characterized in that: The housing further comprises a child safety mechanism disposed on a side wall of the housing, the child safety mechanism comprising a child safety dial button, a child safety connecting rod, and an inward-opening transition rod, the inward-opening transition rod and the inward-opening pull rod coaxially rotating, the inward-opening transition rod having a third hole axis, the child safety connecting rod rotating along the third hole axis under the control of the child safety dial button; the inward-opening transition rod having a second dial block, and the child safety connecting rod having a limiting protrusion; When the child safety dial button is toggled, the child safety connecting rod is triggered to rotate along the third hole axis, so that the limiting protrusion moves to the first state position. The limiting protrusion in the first state position forms a linkage relationship between the inner opening transition rod and the inner opening pull rod, thereby releasing the child safety. When the inner opening pull rod is toggled, the second dial block on the inner opening transition rod toggles the transition pull rod to slide along the long slot in a direction away from the ratchet. Resetting the child safety dial button triggers the child safety connecting rod to rotate along the third hole axis, causing the limiting protrusion to move to the second state position. The limiting protrusion in the second state position cancels the linkage relationship between the inner opening transition rod and the inner opening pull rod, thereby realizing child safety. When the inner opening pull rod is toggled, the inner opening transition rod does not move.
