Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile lock, concretely is a locking and unlocking device of automobile door lock. BACKGROUND

[0002] The door lock is an important component on the vehicle door, and the existing door lock structure utilizes direct transmission, that is, after electric unlocking, the motor drives the unlocking mechanism to enter the unlocking state, at which time unlocking can be performed. For some special customer requirements, multi-stage transmission needs to be designed, and the current lock cannot meet the above requirements. SUMMARY

[0003] To solve the above technical problems, the utility model provides a locking and unlocking device of automobile door lock, which can realize multi-stage transmission unlocking.

[0004] The technical scheme is as follows: a locking and unlocking device of automobile door lock, characterized in that it comprises a worm connected to a motor, a toothed rotating block cooperating with the worm, a long connecting rod movably connected to one end of the toothed rotating block, a locking block provided at the other end of the long connecting rod, a first limiting groove formed in the locking block, a rotatable rotating transmission block provided below the locking block, a second limiting groove formed in the rotating transmission block, a first moving head at one end of the unlocking transmission block movably arranged in the first limiting groove, and a second moving head at the other end movably arranged in the second limiting groove, a torsional spring installed on the locking block and cooperating with the unlocking transmission block, a guide strip provided at the end of the locking block, and a guide seat formed in the door lock housing and cooperating with the guide strip; when the long connecting rod moves left and right, the unlocking transmission block changes position, and the second moving head moves in the second limiting groove.

[0005] After adopting the utility model, a long connecting rod is designed, which drives the unlocking mechanism to unlock. The unlocking mechanism is composed of an unlocking transmission block and a rotating transmission block, which cooperate to complete the switching of the unlocking and locking states, realizing the multi-stage transmission unlocking function.
