The invention relates to the technical field of automobile hooks and discloses an automatic ejection hook for an electric automobile. The automatic ejection hook comprises a thermal bimetallic plate;in a state of vehicle spontaneous combustion, the thermal bimetallic plate is heated to bend rightwards to push a trigger rod to move rightwards; the trigger rod moves rightwards to be inserted into apressing groove; a locking rod is pushed to move downwards under the action of the inclined surface of the inner bottom wall of the pressing groove; the locking rod moves downwards to drive a protruding part to move downwards. The locking of the projection part on the ejection block is relieved; at the moment, the ejection block impacts rightwards under the action of the elastic force of an ejection spring; a punching rod is driven to impact rightwards; a movable block and a hook are ejected out, a firefighter can hook the hook conveniently, then the spontaneous combustion vehicle is draggedaway more conveniently, the trailer is more convenient, the safety of the trailer is improved, and economic losses are reduced; the design is novel, the structure is simple, operation is easy, and theadvantage that the trailer hook can be ejected automatically when the vehicle spontaneously combusts is achieved.

    本发明涉及汽车挂钩技术领域,且公开了一种用于电动汽车的自动弹射挂钩,包括热双金属板,车辆自燃时,热双金属板受热向右弯曲推动触发杆向右移动,触发杆向右移动插进压槽中,并在压槽内底壁斜面的作用下推动锁定杆向下移动,锁定杆向下移动带动凸起部向下移动,解除凸起部对弹射块的锁定,此时弹射块会在弹射弹簧的弹力作用下向右冲击,进而带动冲杆向右冲击,把活动块和挂钩弹射出去,方便消防人员勾取挂钩,进而把自燃车辆拖走,拖车更加的方便,不仅增加了拖车的安全性,也减少了经济损失,本发明设计新颖,结构简单,操作容易,具有车辆自燃时能够自动弹射拖车挂钩的优点。
