Abstract

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.

Description

technical field

[0001] The invention relates to the technical field of automobile hooks, in particular to an automatic ejection hook for electric automobiles. Background technique

[0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Due to the smaller impact on the environment than traditional cars, the prospect of electric vehicles is widely optimistic, but the current technology of electric vehicles is not mature, one of the more important points is that there is a certain risk of spontaneous combustion in the batteries of electric vehicles, especially It is a new energy vehicle with ternary lithium.

[0003] When a car spontaneously ignites, in some cases, in order to reduce losses, it is necessary to quickly remove the accident vehicle from its original position to prevent fires or casualties. However, the flame when t...
