Integrated type vehicle door lock for heavy-truck light-truck commercial vehicle

Abstract

The invention discloses an integrated type vehicle door lock for a heavy-truck light-truck commercial vehicle. The integrated type vehicle door lock 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 furthercomprises a motor, a worm and a gear sub assembly. According to the integrated type vehicle door lock, the inner opening inner locking function and the outer opening outer locking function can be finally achieved through the mutual meshing effect of a ratchet wheel and a pawl; a ratchet wheel signal rocker arm and a microswitch are further arranged so that signal transmission of the vehicle doorstate information can be realized; and the locking and unlocking state signals of the vehicle door lock can be transmitted through the microswitch making contact with the locking linkage block so thatthe center control function of a left vehicle door lock and a right vehicle door lock can be achieved conveniently. The vehicle door lock is of an integrated structure and has the advantages of beingcompact 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 technical field of automobile door locks. More specifically, the present invention relates to an integrated door lock for heavy truck and light truck commercial vehicles. Background technique [0002] The existing car door lock is basically a split structure, the circuit part and the mechanical part are separated, and its locking or unlocking is realized through the connection and transmission of the pull rod of the electric actuator and the mechanical part of the lock body. If there is a deviation in the relative installation position or the deformation of the parts, it will cause a series of performance instability such as the feedback signal, which will affect the user's use. And the lock body of the present invention is an integral lock body, and its actuator and the lock body are integrated, and the above problems can be effectively avoided by the transmission of the internal gear and worm. The integrated lock body i...
