Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, the present embodiment provides an automobile hood lock opening mechanism, which includes: the unlocking driving lever 1, the lock catch 5 and the engine cover lock assembly 3.

The opening shift lever 1 is installed on the front bumper upper cover plate 2, and the engine hood lock assembly 3 is covered by the front bumper upper cover plate 2 and partially exposed. The engine cover bounces after primary unlocking, and a handle at the end part of the opening shifting rod 1 is exposed at the edge of the upper cover plate 2 of the front bumper, so that discovery and identification are facilitated.
