17 B multi-functional door lock assembly

Abstract

The invention discloses a 17 B multi-functional door lock assembly. The door lock assembly comprises a lock body, an opening rocker arm, an outer opening rocker arm, an inner opening rocker arm, a locking push rod, an outer locking rocker arm, a locking linkage block, an inner locking rocker arm and an inner locking linkage arm, and further comprises a motor, a worm, and a gear division assembly;functions of inner opening, outer opening and locking are achieved through mutual meshing effect of ratchets and pawls; the door lock assembly further comprises a ratchet signal rocker arm and a microswitch, and the signal transmission of vehicle door state information can be realized; and the microswitch in contact with the locking linkage block can realize the transmission of vehicle door lock locking and unlocking state signals so as to realize a central control function of a left door lock and a right door lock. According to the door lock assembly, the vehicle door lock is of an integratedstructure, and has the advantages of having a double-pull function, being compact in structure, good in dustproof and waterproof performance, high in transmission efficiency, better in control performance and the like.

Description

technical field [0001] The invention relates to the field of door locks, in particular to a 17B multifunctional door lock assembly. Background technique [0002] At present, most of the car door locks are split-type door locks. The locking or unlocking of the split-type door locks is realized through the connection and transmission of the pull rod of the electric actuator and the mechanical part of the lock body, but the relative installation of the electric actuator and the mechanical part of the lock body The position is easy to deviate, and the parts of the two are also easy to deform, which will cause the feedback signal to be unstable and affect the user's use. Moreover, because the electric actuator and the mechanical part of the lock body are two separate structures, they need to be separated during use. Connected together, this will greatly increase the number of structural parts, which not only increases the manufacturing cost, but also makes the assembly of the spl...

[0002] At present, most of the car door locks are split-type door locks. The locking or unlocking of the split-type door locks is realized through the connection and transmission of the pull rod of the electric actuator and the mechanical part of the lock body, but the relative installation of the electric actuator and the mechanical part of the lock body The position is easy to deviate, and the parts of the two are also easy to deform, which will cause the feedback signal to be unstable and affect the user's use. Moreover, because the electric actuator and the mechanical part of the lock body are two separate structures, they need to be separated during use. Connected together, this will greatly increase the number of structural parts, which not only increases the manufacturing cost, but also makes the assembly of the split lock body more complicated, and in order to ensure the structural strength of the split lock, it can only increase the manufacturing accuracy requirements of the parts
