When the vehicle reconnection is completed, the locking mechanism 5 is unlocked, and the locking driving piece 52 drives the locking piece 53 to retract, namely, the locking of the guide piece 4 is released; after the locking member 53 is retracted, the locking drive member 52 is self-locking. Then, the guide driving member 31 is unlocked, the guide driving member 31 drives the guide member 4 to retract, and since the guide driving member 31 itself is provided with a self-locking structure, when the guide driving member 31 is retracted to the original state, the guide driving member 31 performs self-locking, so that the guide member 4 is in a retracted and locked state. The space occupied by the guide 4 is now significantly reduced. Thereby solving the technical problem that the vehicle hood can not realize compact design due to the large occupied space of the guide piece 4 in the prior art.
