Integrated front door lock

Abstract

The invention discloses an integrated front door lock which comprises a lock body (6), a lock body cover plate (1), a lock body seat plate (7), a shell cover (11), a worm gear (21), a worm (22) and a motor (23), wherein a shock absorbing block (4), a T-type rubber block (3), a ratchet shock absorbing block (47) and a micro switch I (5) are installed in the lock body (6), the lock body (6) is covered with the lock body cover plate (1), the side, departing from the lock body cover plate (1), of the lock body (6) is provided with the lock body seat plate (7) which is provided with a pawl (46) for installing a pawl torsional spring (8), the pawl (46) is riveted to the lock body seat plate (7) through a ratchet shaft (9), and a pawl linkage arm (10) is installed on the pawl (46) and used for fixing the pawl torsional spring (8) in a riveted mode. The integrated front door lock is stable in signal feedback, high in transmission efficiency and stable in structure.

Description

technical field [0001] The invention relates to the technical field of automobile door locks, in particular to an integrated front door lock body. Background technique [0002] At present, car front door locks usually use split door locks. The actuator of the split door lock is separated from the lock body. Its locking or unlocking is achieved by connecting the pull rod of the electric actuator with the mechanical part of the lock body to achieve transmission. The actuator and the lock If the relative installation position of the body is deviated or the parts are deformed, the feedback signal will be unstable, which will affect the user's use, the noise will be too large during use, and the transmission efficiency will be low. The one-piece lock body is an improved product of the split-type lock body. It is the result of the integration of the split-type door lock and the electric control actuator of the door lock. It is the development trend of the door lock body at home an...

Problems solved by technology

[0002] At present, car front door locks usually use split door locks. The actuator of the split door lock is separated from the lock body. Its locking or unlocking is achieved by connecting the pull rod of the electric actuator with the mechanical part of the lock body to achieve transmission. The actuator and the lock If the relative installation position of the body is deviated or the parts are deformed, the feedback signal will be unstable, affecting the user's use, the noise is too large during use, and the transmission efficiency is low

The one-piece lock body is an improved product of the split-type lock body. It is the result of the integration of the split-type door lock and the electric control actuator of the door lock. It is the development trend of the door lock body at home and abroad. It has compact structure, excellent dustproof and waterproof, The advantages of high transmission efficiency, the disadvantage is that the manufacturing precision of parts is high, and the production cost is relatively high
