Abstract

The invention discloses an electric automobile collision power-off switch trigger mechanism. A switch box upper body and a switch box lower body are in fixed connection. A center of the switch box upper body is opened with a through hole. A mandrel passes through the through hole from top to bottom. A middle part of the mandrel is fixed provided with a position sleeve. An upper end of the position sleeve is connected with the switch box upper body through a butterfly steel wire. A lower end of the position sleeve is fixedly provided with a switch motion block. A front wiring block and a back wiring block are provided between the switch box upper body and the switch box lower body, and both the wiring blocks contact with the switch motion block. According to the invention, when an electric automobile is in collision, a circuit supplying power outwardly of a power battery pack can be automatically and rapidly cut off, electric leakage caused by collision is avoided, a problem of vehicle electric leakage of the electric automobile caused by collision is solved, and a safety requirement of the electric automobile is satisfied. The electric automobile collision power-off switch trigger mechanism employs a mechanical structure and has the advantages of simple structure, easy assembly, and sensitive and reliable working, a complex circuit and a complex software system are avoided, and production cost is low.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a trigger mechanism of a collision power-off switch on the electric vehicle. Background technique [0002] At present, the technology of new energy vehicles, especially electric vehicles, has gradually matured, and electric vehicles have entered the stage of test and demonstration operation. During the use of electric vehicles, collisions will inevitably occur, and after the collision, leakage will occur due to damage to the high-voltage circuit such as insulation damage, which will cause the body and chassis to be charged, which will easily cause secondary injuries to the occupants and vehicles, and even cause Start a fire. How to maximize the safety of people and vehicles in the car and meet the safety requirements of electric vehicles is a technical problem that electric vehicle companies need to solve urgently. Contents of the invention [0003] The ...
