Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-7, in the mechanical lock device of the vehicle door, an outer lock cover 1, an inner lock cover 3 and a guide frame 4 are fixedly installed on a passenger car door leaf, one end of a lock pin 5 penetrates through the guide frame 4 fixed with the passenger car door leaf, an outer sleeve spring 6 is sleeved on the outer side of the lock pin, the other end of the lock pin is hinged with an operation plate 10 through a connecting rod 7, the operation plate 10 is sleeved on a connecting shaft 11, the connecting shaft 11 penetrates through the inner lock cover 3 to be fixedly connected with a handle 2, a lock cylinder 8 is fixed on the outer lock cover 1, and a lock cylinder connecting rod 9. The inner locking cover 3 is formed with a locking groove 12 having a locking end 13 and an unlocking end 14 at both ends thereof. The pin 15 and the connecting rod 7 can slide in the locking groove 12, wherein the pin 15 is close to the locking end 13 and the connecting rod 7 is close to the unlocking end 14. The pin 15 is fixedly connected to the handle 2.

As shown in fig. 8-9, when the utility model is used, the locking outside the vehicle is: a key is inserted into the lock cylinder 15 to rotate anticlockwise so as to drive the lock cylinder connecting rod 9 to rotate, the lock cylinder connecting rod 9 is contacted with the operating panel 10, and the operating panel 10 synchronously rotates anticlockwise so as to drive the connecting rod 7 to enter the groove locking end 13 and enter a dead point position; the lock pin 5 is connected with the operating panel 10 through the connecting rod 7 and is pushed out in a linkage mode with the operating panel 10, the spring 6 is in a compression state at the moment, the spring 6 cannot reset due to the fact that the operating panel 10 enters a dead point position, and the lock pin 5 can keep an extending state to achieve locking.

Unlocking outside the vehicle: a key is inserted into the lock core 15 to rotate clockwise to drive the lock core connecting rod 9 to rotate, the lock core connecting rod 9 is contacted with the operating panel 10, and the operating panel 10 synchronously rotates clockwise to drive the connecting rod 7 to leave the groove locking end 13 and separate from a dead point position; the spring 6 resets to push the lock pin 5 to move, the connecting rod 7 and the operating panel 10 are linked to the groove unlocking end 14, and the lock pin 5 retracts to realize unlocking.

Unlocking in the vehicle: when the mechanical lock is in a locking state, the operating handle 2 rotates anticlockwise, the pin shaft 15 rotates synchronously, and the pin shaft 15 pushes the connecting rod 7 to slide along the locking groove 12, leave the groove locking end 13 and leave a dead point position; the spring 6 resets to push the lock pin 5 to move, the connecting rod 7 and the operating panel 10 are linked to the groove unlocking end 14, and the lock pin 5 retracts to realize unlocking.

Preventing the inside of the vehicle from being locked: when the mechanical lock is in an unlocking state, the operating handle 2 rotates clockwise, the pin shaft 15 rotates synchronously, the pin shaft 15 is close to the locking end 13, the connecting rod 7 is close to the unlocking end 14, the pin shaft 15 can only idle to the locking end 13 along the locking groove 12, and cannot be linked with the connecting rod 7, so that the locking of the mechanical lock cannot be realized, and the situation that the door cannot be opened normally due to the locking of the door caused by misoperation of passengers is prevented.

Noise reduction: during the running process of the vehicle, the mechanical lock is in an unlocking state, the spring 6 applies thrust to the lock pin 5, the thrust is decomposed to the operating plate 10 along the connecting rod 7, the operating plate 10 is pressed to be in the groove unlocking end 14, a balance state is achieved, the movement of the lock pin 5 and the rotation of the operating plate 10 are reduced, and therefore noise during the running process of the vehicle is reduced.
