All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Embodiments of the present invention are described below with reference to fig. 1 to 3.

According to an embodiment of the present invention, in one aspect, there is provided a locker applied to a vehicle having an active protection hood system, the vehicle including a front cover 5 provided at a front end of a vehicle body and a lock engagement device, the locker comprising: the lock comprises a mounting seat 1, a lock body 2 and a locking structure 4, wherein the mounting seat 1 is suitable for being fixedly arranged at the bottom of the front end of a front cover 5, the lock body 2 is movably arranged at the mounting seat 1 through a first driving structure, the lock body 2 is suitable for being matched with a locking matching device to fix the front cover 5, the lock body 2 is provided with a jacking state moving away from the front cover 5 and jacking the front cover 5 to a preset height and an initial state moving close to the front cover 5 and returning the front cover 5 to the initial height, at least one side of the lock body 2 is provided with the locking structure 4, each locking structure 4 comprises a locking seat 401 and a stop assembly, the stop assembly is telescopically arranged at the locking seat 401 through a second driving structure, the stop assembly is provided with a first abutting surface 4021 and a second abutting surface 4031, the locking structure 4 is provided with an unlocking state enabling the lock body 2 to move relative to the mounting seat 1, and is provided with a first locking state enabling the lock body 2 to be matched with the lock body 2 through the first abutting surface 4021 and enabling the lock body 2 to be kept in the jacking state, and a second locking state is kept in the initial locking state by the second abutting surface 4031.

By applying the locking device of the embodiment, the locking structure 4 is arranged on one side of the lock body 2, the lock body 2 can move relative to the mounting seat 1 through the first driving structure, after the front cover 5 is matched with the lock body 2 through the lock body 2 in an initial state and the locking matching device, the second abutting surface 4031 of the stop component is matched with the lock body 2 at the moment, so that the lock body 2 and the mounting seat 1 form a whole, the front cover 5 is prevented from being fixed and unstable due to random movement of the lock body 2, when the rear end of the front cover 5 is actively lifted, the stop component is switched to an unlocking state, the first driving structure drives the lock body 2 to rapidly lift the front end of the front cover 5, the stop component is changed into a second locking state through the first abutting surface 4021 in a matched manner with the lock body 2, and the lock body 2 at the moment forms a whole again, the front cover 5 can still keep a lifting state when the front cover 5 is impacted, a certain lifting height is avoided, the front cover 5 can be stably kept, the front cover 5 cannot be easily damaged around the front cover 2, and the existing interference structure can not be easily solved when the front cover is actively lifted.

Specifically, the first driving structure of the embodiment is an active driving structure, when the first driving structure is in an active state, the lock body 2 can be actively driven to move, when the locking structure 4 is changed into an unlocking state, if the first driving structure is in an inactive state, the lock body 2 can not move at will, so that the situation that the lock body 2 freely jacks up the front cover 5 in a normal state is avoided;

compared with a passive energy storage driving structure such as a spring and the like, the spring is in a continuous compression state in a normal state, if the structure for maintaining the spring in the compression state is loosened, the spring is easy to break through the compression structure to be directly in an excited state to stretch and jack the front end of the front cover 5 when no accident occurs to the vehicle, and the structural reliability is insufficient.

Meanwhile, the requirement of the active front cover 5 from triggering to bouncing to a specified height is usually completed within 25ms, and the spring is in a compressed state for a long time, so that the spring is easy to reach the fatigue limit and lose efficacy, meanwhile, the weight load of the front cover is bounced only by virtue of the spring force, the bouncing time is ensured, and the lifting speed and the lifting force provided when the front cover 5 is lifted are limited.

Further, after the front cover 5 is lifted by the spring in the passive energy storage driving structure, no additional locking device is provided, so that the front end of the front cover 5 falls back when external force is applied, and the stop assembly of the embodiment can ensure that the lock body 2 keeps a lifting state through the first abutting surface 4021, thereby effectively improving the lifting reliability.
