The invention discloses a lock catch structure, a hood lock, a vehicle and a design method for the crushing force of the hood lock, and relates to the technical field of vehicles. The lock catch structure is used for the vehicle and comprises a lock ring and a pressing ring, the lock ring is suitable for being locked or unlocked with a lock body on a vehicle body, the pressing ring is installed on the lock ring, the pressing ring is suitable for being connected with a hood, and under the action of collision force, the pressing ring deforms under the load effect so that the hood can move downwards relative to the lock ring. According to the lock catch structure, when collision occurs, collision force acts on the hood, so that the hood can directly or indirectly extrude the pressing ring, the pressing ring deforms under the load effect, the hood moves downwards relative to the lock ring, the acting force of the hood on the head of an impacted person is reduced, the impact acceleration borne by the head of the impacted person is reduced, and the safety of the head of the impacted person is improved. Therefore, the impacted person can be effectively protected.
本申请公开了一种锁扣结构、机罩锁、车辆及机罩锁压溃力的设计方法,涉及车辆技术领域。该锁扣结构用于车辆,锁扣结构包括锁环和压环,锁环适于与车身上的锁体锁止或解锁,压环安装于锁环,压环适于与机罩连接,在碰撞力的作用下,压环受荷载作用发生形变,以使机罩相对于锁环向下移动。根据本申请的锁扣结构,在碰撞发生时,碰撞力作用于机罩上,使机罩能够直接或间接挤压压环,压环受荷载作用发生形变,以使机罩相对于锁环向下移动,有利于减小机罩对被撞击者头部的作用力,降低被撞击者头部受到的冲击加速度,从而能够有效保护被撞击者。
