Automatic lock of push-pull automobile door

Abstract

The invention relates to the field of automobile parts, and discloses an automatic lock of a push-pull automobile door. The automatic lock comprises a bottom plate, as well as a double-gear lock body, an unlocking mechanism, a first switch, a second switch, a third switch, a ratchet, a first transmission pair, a first paddle, a controller and a motor which are arranged on the bottom plate, wherein the double-gear lock body comprises a three-jaw lock piece and a lock body transmission mechanism. According to the lock, the automobile door is gently pushed and closed to allow the three-jaw locking piece to rotate; first gear locking is realized; the motor controls the first transmission pair to drive the first paddle to push the three-jaw locking piece to continuously rotate to automatically realize second gear locking after the first gear locking; even if the force of closing the door is very small, the automatic second gear locking can be realized as long as the first gear locking can be ensured; the automobile door is locked; the safety during travelling is ensured; and the damage to the automobile door is reduced.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a push-pull automatic door lock. Background technique [0002] Sliding doors are widely used in box-type vehicles such as vans and RVs. Sliding doors generally need to be locked with a second gear lock to ensure the safety of people in the car. The existing sliding door locks generally include a base plate and a second gear lock on the base plate. Body and unlocking mechanism, the second gear lock body includes a three-claw lock and related lock body transmission mechanism, the three-claw lock can rotate and cooperate with the lock hook to lock the car door. The unlocking mechanism cooperates with the lock body transmission mechanism to realize the unlocking of the three-jaw lock body. The second gear of the existing push-pull door lock adopts a mechanical lock, which needs a large driving force to be locked artificially, and there is no device for detecting whether the second gear is ...

AI Technical Summary

Problems solved by technology

The second gear of the existing push-pull door lock adopts a mechanical lock, which needs a large driving force to be locked artificially, and there is no device for detecting whether the second gear is locked. The above-mentioned defects will cause, on the one hand, the door may appear It is possible to drive without being locked, which will make the safety of people and objects in the car not guaranteed. On the other hand, in order to ensure that the second gear is locked, it takes a lot of effort to lock the sliding door. It is easy to damage the car body
