Description
Technical Field

Background
Motor vehicle door locks usually have a mechanical locking device for locking a specific operating device, for example a door handle, so that unauthorized operation (for example a thief) cannot open the door into the vehicle. In modern motor vehicles, this design is usually equipped with at least one motor integrated inside the door lock, which allows the electric actuation of the above-mentioned locking decoration, working in conjunction with the anti-theft and safety modules of the entire vehicle. This function is also referred to as central locking. At the same time, the national standard also requires that the locking state must be electrically released in the case of motor vehicle collision, so that people outside the vehicle can rescue the vehicle.
In particular, some vehicle models are equipped with an electric opening device. The motor vehicle door with the device does not need to pull a mechanical handle to reach specified displacement by conventional force, and the vehicle body can drive the door lock to be electrically unlocked only by pressing a specific button or slightly operating a handle to trigger a switch, so that the operation comfort is obviously improved. This function is also referred to as electrically opening the door. Generally, the function can be realized by separately providing a motor and a corresponding transmission mechanism.

A fuse member 109 is rotatably mounted on the housing for arming and disarming. When the direction of fig. 1 and 2 is viewed, the clockwise rotation of the safety member 109 is for unlocking, the safety member 109 drives the locking unit (not shown in the figure, which is a locking structure in the prior art) to enable the door lock to enter the unlocking mode, the counterclockwise rotation of the safety member 109 is for locking, and the safety member 109 drives the locking unit to enable the door lock to enter the locking mode.
The swing link 110 is rotatably mounted on the housing.
One end of the safety lever 111 is rotatably mounted on the safety member 109, and the other end is rotatably mounted on the swing lever 110. As shown in fig. 1, the swing link 110 and the safety member 109 are respectively located at both sides of the first gear 102 and the second gear 107, and the safety lever 111 passes through the first gear 102 and the second gear 107.
The bumper 111 is provided with a first protrusion 1111, a second protrusion 1112, and a third protrusion 1113.
The first protrusion 1111 and the second protrusion 1112 are located in a section of the second gear 107 where the safety lever 111 passes, the first protrusion 1111 is located on the end side of the swing link of the eccentric protrusion 71, the second protrusion 1112 is located on the end side of the safety member of the eccentric protrusion 71, and the height of the eccentric protrusion 71 can push the first protrusion 1111 or the second protrusion 1112 when the second gear 107 rotates. The partial areas of the first protrusion 1111 and the second protrusion 1112 are located within the circumference of the eccentric protrusion 71. The third protrusion 1113 corresponds to the sliding member 41, and when the safety lever 111 moves, the safety lever 111 drives the third protrusion 1113 to move away from or press the sliding member 41.
When the first gear 102 is in the non-unlocking position, i.e., the initial position, the securing member 109 is in the upper securing state, and the radius of the coupling member 42 from the center of the first gear 102 is larger than the radius of the small radius arc of the first recess 21, the eccentric protrusion 71 is close to the second protrusion 1112, the first return spring 105 is in the free state, the second return spring is in the free state, and the third return spring 108 is in the free state.
The distance from the third protrusion 1113 to the sliding member 41 and the shape of the safety lever 111 are such that when the first gear 102 is in the non-unlocking position, the safety member 109 is in the upper safety state, and the radius from the coupling member 42 to the center of the first gear 102 is greater than the radius of the small-radius arc of the first groove 21, when the first gear 102 drives the second gear 107 to rotate, such that the second gear 107 drives the eccentric protrusion 71 to rotate towards the second protrusion 1112, and pushes the second protrusion 1112 to push the safety lever 111 to move, and when the safety lever 111 pushes the safety member 109 from the upper safety state to the lower safety state, the third protrusion 1113 can compress the coupling block 104, such that the radius from the coupling member 42 to the center of the first gear 102 is less than or equal to the radius of the small-radius arc of the first groove 21. The distance between the first protrusion 1111, the second protrusion 1112 and the eccentric protrusion 71 is such that after the third return spring 108 returns the second gear 107, the eccentric gear 71 approaches the first protrusion 1111; and the distance between the first protrusion 1111, the second protrusion 1112 and the eccentric protrusion 71 is such that when the first gear 102 is at the non-unlocking position (initial position), the safety member 109 is in the upper safety state, and the radius from the coupling member 42 to the center of the first gear 102 is greater than the radius of the small radius arc of the first groove 21 (during coupling), when the first gear 102 drives the second gear 107 to rotate, so that the second gear 107 drives the eccentric protrusion 71 to rotate towards the first protrusion 1111, the guide block 103 pushes the shift lever 106 to rotate, and when the shift lever 106 shifts the unlocking unit to complete unlocking, the eccentric protrusion 71 cannot contact the first protrusion 1111.
Specifically, the first protrusion 1111 and the second protrusion 1112 are disposed in parallel with each other, and form an acute angle with the bumper 111 toward an end of the bumper 111 where the safety member 109 is installed. The first projection 1111 and the second projection 1112 are both parallel to the gear face of the second gear 107. The third protrusion 1113 is located at one end of the bumper 111 where the swing link is installed.
In this embodiment, the end of the safety lever 111 where the safety member is installed is provided with a strip-shaped hole 1114, the safety member 109 is provided with a second rotating shaft 91, the second rotating shaft 91 is installed in the strip-shaped hole 1114, the second rotating shaft 91 can slide in the strip-shaped hole 1114 and can also rotate in the strip-shaped hole 1114 relative to the strip-shaped hole.
As shown in fig. 7, the action of the motor vehicle door lock of the present invention in a specific use is as follows:
action process 1: when the door lock is locked, the first gear 102 is at the initial position, the securing member 109 is in the secured state, and the radius from the coupling member 42 to the center of the first gear 102 is greater than the radius of the small radius arc of the first groove 21 (at the time of coupling), the eccentric protrusion 71 approaches the second protrusion 1112, that is, the state in fig. 1 starts. When the direction of fig. 1 is seen, the motor 11 drives the first gear 102 to rotate clockwise through the worm 12, and drives the guide block 103 to rotate clockwise, so as to push the shift lever 109 to rotate, the shift lever 109 rotates, the unlocking unit is shifted to unlock, after unlocking is completed, the motor 11 stops rotating, and the shift lever 109 resets under the elastic force of the second return spring; when the first gear 102 rotates clockwise, the second gear 107 is driven to rotate anticlockwise, the eccentric protrusion 71 rotates anticlockwise, when the first gear 102 stops rotating, the eccentric protrusion 71 does not contact the first protrusion 1111, the safety lever 111 does not move, decoupling and unlocking are not performed, and only the unlocking task is performed. After the motor 11 stops rotating, the second gear 107 is reset by clockwise rotation and the first gear 102 is reset by counterclockwise rotation by the elastic force of the third return spring 108.
Action process 2: starting from the state shown in fig. 1, when the motor 11 drives the first gear 102 to rotate counterclockwise through the worm 12 as viewed in the direction of fig. 1, since the step surface 211 moves in the opposite direction of the coupling member 42, the first gear 102 cannot rotate to drive the coupling block 104 to rotate and further cannot drive the guide block 103 to rotate, and thus, the unlocking cannot be performed; the first gear 102 rotates counterclockwise to drive the second gear 107 to rotate clockwise, the second gear 107 drives the eccentric protrusion 71 to rotate clockwise to push the second protrusion 1112, so that the safety rod 111 moves to drive the safety member 109 to rotate clockwise, the safety is relieved from the upper safety state, the safety rod 111 moves to simultaneously press the third protrusion 1113 against the coupling block 104, so that the coupling block 104 moves towards the center of the first gear 102, and when the safety member 109 is relieved from the upper safety state to the lower safety state, the radius from the coupling member 42 to the center of the first gear 102 is smaller than or equal to the radius of the small radius arc of the first groove 21. After the safety relief is completed, the motor 11 stops rotating, and under the action of the elastic force of the third return spring 108, the second gear 107 rotates counterclockwise to reset, and drives the first gear 102 to rotate clockwise to reset, at this time, the eccentric protrusion 71 is close to the first protrusion 1111, and the state of the motor vehicle door lock is as follows: when the first gear 102 is in the initial position, the securing member 109 is in the unsecured state, and the radius of the coupling member 42 to the center of the first gear 102 is smaller than or equal to the radius of the small radius arc of the first groove 21 (decoupled).
Then, as seen in the direction of fig. 1, the motor 11 drives the first gear 102 to rotate clockwise through the worm 12, so as to drive the second gear 107 to rotate counterclockwise, the second gear 107 drives the eccentric protrusion 71 to rotate counterclockwise, the eccentric protrusion 71 pushes the first protrusion 1111, so as to push the safety lever 111 to move, and the safety lever 111 drives the safety member 109 to rotate counterclockwise, so as to complete the upper safety from the safety release state; meanwhile, since the coupling member 42 is in the decoupling state, when the first gear 102 rotates clockwise, the step surface 211 cannot contact the coupling member 42, and therefore, the first gear 102 cannot rotate to drive the coupling block 104 to rotate, when the safety lever 111 moves leftward and the third protrusion 1113 moves away from the center of the first gear 102, the third protrusion 1113 slowly releases the extrusion on the coupling block 104, but at this time, because of the limitation of the small radius arc of the first groove 21, the first return spring 105 is still in the compressed state, the first gear 102 cannot rotate to drive the coupling block 104 to rotate, and therefore, the guide block 103 cannot be driven to rotate, and therefore, unlocking cannot be performed. After the upper insurance is completed, the motor 11 stops rotating, the second gear 107 rotates clockwise to reset under the action of the elastic force of the third return spring 108, the first gear 102 is driven to rotate anticlockwise to reset, after the first gear 102 resets, the sliding member 41 slides along the guide block towards the center far away from the first gear 102 under the action of the elastic force of the first return spring 105, the radius from the coupling member 42 to the center of the first gear 102 is larger than the radius (coupling) of the small-radius arc of the first groove 21, at this time, the eccentric protrusion 71 is close to the second protrusion 1112, and the state of the motor vehicle door lock is the state shown in fig. 1.
The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.
