Automobile electric tailgate locking device

Abstract

The invention discloses a locking device for an electric tail gate of a vehicle, which comprises a base, a pull ring, a support assembly and a pull wire, wherein the pull ring is movably arranged on the base, the support assembly supplies acting force which can enable the pull ring to be still kept in a locking position when the pull ring is subjected to impact of a tail gate lock, and the pull wire is connected with the support assembly. According to the locking device for the electric tail gate of the vehicle, by arranging the support assembly interactive with the pull ring, the support assembly can be still kept in the locking position when the pull ring is subjected to the impact force generated by the tail gate lock so as to enable the pull ring not to move, so that the pull wire can not be bent or broken, thereby ensuring the service life of the pull wire.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular, the invention relates to an electric tailgate locking device for automobiles. Background technique [0002] The electric tailgate locking device on the existing automobile relies on spring force to counteract the impact force when the tailgate is closed. This structure has the following defects: [0003] 1. At the moment when the tailgate is closed, the pull ring on the locking device will move downward correspondingly due to the impact force of the tailgate. If the state of the spring does not change, it cannot offset the impact caused by the collision between the tailgate lock and the pull ring. The impact force / kinetic energy generated forces the cable to bend, because the cable is a steel wire, which is easy to break when bent; [0004] 2. Because the spring will be deformed, the pull ring will move backwards, so the tailgate needs a relatively large impact force to allow ...

AI Technical Summary

Problems solved by technology

[0003] 1. At the moment when the tailgate is closed, the pull ring on the locking device will move downward correspondingly under the impact force of the tailgate. If the state of the spring does not change, it cannot offset the impact caused by the collision between the tailgate lock and the pull ring. The impact force / kinetic energy generated forces the cable to bend, because the cable is a steel wire, which is easy to break when bent;

[0004] 2. Because the spring will be deformed, the pull ring will move backwards, so the tailgate needs a greater impact force to make the tailgate secondary lock catch the pull ring of the locking device, and the noise generated is louder
