Electrically opening trunk lock capable of reliably being opened

Abstract

The invention discloses an electrically opening trunk lock capable of reliably being opened. The electrically opening trunk lock comprises a motor, wherein the motor is in transmission connection with an unlocking mechanism; the unlocking mechanism is in transmission connection with a meshing locking device which has a locking state and an opening state. The electrically opening trunk lock also comprises an electric control device, an opening state detection device and a box cover opening degree detection mechanism, wherein the electric control device is respectively connected with the motor, the opening state detection device and the box cover opening degree detection mechanism; when in unlocking, a trunk lock opening state signal is sent out to the electric control device by the opening state detection device; the motor is stopped rotating by the electric control device; after the trunk lock is opened formerly, the box cover is slightly bounced upwards; before the box cover is opened, the box cover is easy to fall back at the force of gravity, so that the meshing locking device is relocked; the meshing locking device can be kept opening state through the motor by the arrangement of the electric control device and the opening state detection device, even if the box cover falls back, the electrically opening trunk lock can not be meshed and locked again, so that the opening reliability is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a trunk lock with an electric opening function. Background technique [0002] With the rapid development of the global economy, automobiles are gradually becoming popular in people's lives as a consumer product, and people have higher and higher requirements for the intelligence and comfort of automobiles. Existing cars are generally equipped with BCM body control modules, and sensors (such as gated light switches) are often used to detect the position of various components in the car body. [0003] At present, the electric opening process of the luggage lock with electric opening function is: the motor rotates and the dead bolt rotates through the transmission mechanism, disengages from the lock hook, and the lock hook rotates downward to release the restriction on the lock cylinder to realize opening. This opening method has the disadvantage of unreliable open...

AI Technical Summary

Problems solved by technology

This opening method has the disadvantage of unreliable opening: after opening, the trunk lid and the trunk lock fall back down under the action of gravity, which will easily cause the lock hook and the dead bolt to reset and re-engage together, so that the trunk lid will be re-engaged. atresia

For the trunk lock with electric locking function, since the trunk lid only needs to be pressed to the half-lock position to trigger the door control light switch, the required force is small, so it is easier to open the trunk lid and fall back to the half-lock position , causing the trunk lock to lock again

[0005] At present, there is no luggage lock on the market that can solve the above-mentioned problem of unreliable opening without relying on the electric lift system
