electric hood lock

Abstract

The invention discloses an electric hood lock, which comprises a lock tongue, a lock buckle, a safety baffle, a drive motor connected to the lock tongue and the safety baffle through a transmission mechanism, and a remote control key. When it is necessary to open the hood lock, press the Press the unlock button of the remote control key once, the drive motor will rotate forward, and the safety baffle will be switched from the locked state to the unlocked state through the transmission mechanism; press the unlock key of the remote control key again, the drive motor will continue to rotate forward, and through the transmission mechanism Drive the lock tongue to switch from the locking position to the release position, and the lock buckle and the lock tongue are disengaged at this time; when the cover lock needs to be closed, press the lock key of the remote control key, and the drive motor reverses to reset, and the lock tongue is released first. The position is reset to the locked position; then the safety baffle is reset from the unlocked state to the locked state. On the premise of ensuring the safe opening of the machine cover lock, the present invention can realize the automatic opening and closing of the machine cover lock, thereby being convenient to use, simple in structure, and beneficial to processing, manufacturing and popularization.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle manufacturing, and in particular relates to an electric hood lock. Background technique [0002] The existing automobile front cover usually includes a deadbolt and a buckle arranged between the front cover and the vehicle body, and two sets of control mechanisms for unlocking the deadbolt and the catch are provided, wherein one set of control mechanisms is arranged in the cab, Another set of control mechanisms is set in the front cabin. When opening the hood lock, you need to manually open the catch in the cab, and then go to the front hood and manually toggle the second gear lock hook to open the front hood, thereby ensuring the safety of the front hood and avoiding accidents caused by drivers. Mishandling in the cab resulted in the sudden opening of the front hood. Although this machine cover lock structure and corresponding unlocking method can improve safety performance, there are ...

AI Technical Summary

Problems solved by technology

Although this machine cover lock structure and corresponding unlocking method can improve safety performance, there are following defects: there are many action steps, and it is troublesome to unlock. Then go to the front cover and open the second gear lock hook

[0003] Although there are also people who try to use motors to realize the automatic opening of the hood lock, for safety reasons, the hood lock needs to include two opening steps, and accordingly, it needs to have two reset steps, and the opening step and the reset step The sequence is opposite. Generally, people need to use two motors (or corresponding power components) and set up two sets of locking systems to realize the partial opening of the cover lock, which will cause the overall structure of the cover lock to be complicated.
