Description

Emergency power-off device and emergency power-off method for vehicle accident Technical Field The invention belongs to the technical field of vehicle safety devices, and particularly relates to a vehicle accident emergency power-off device and an emergency power-off method. Background At present, a fuse is generally used for preventing spontaneous combustion caused by overlarge current when a circuit is in short circuit of a vehicle, but the fuse is easily changed by privacy, so that the situation that the circuit is in short circuit to cause the ignition of the vehicle in the past due to accident collision is that, in particular, the situation that inflammables such as vehicle-mounted oil gas and the like are burnt once the inflammables are burnt, the risk degree is higher, and the situation that people are trapped, alive and burned is also frequent. Disclosure of Invention In order to overcome the technical problems, the invention provides the emergency power-off device and the emergency power-off method for the vehicle accident, which are used for cutting off the power supply of the whole vehicle by means of the inertia of the vehicle when the accident occurs, preventing the short circuit of the circuit from firing, protecting the life safety of the vehicle owner and preventing property loss. The invention adopts the following technical scheme: The utility model provides a vehicle accident emergency power-off device, includes the shell, set up spud pile and activity stake in the shell, the spud pile has terminal one, the activity stake has terminal two, activity stake and spud pile dock in order to communicate terminal one and terminal two electricity mutually, set up the inertial hammer in the shell, the inertial hammer drives the activity stake and leaves the spud pile in order to break off terminal one and terminal two when the device meets the impact. Preferably, the fixed pile is fixedly arranged on the bottom wall of the shell, the movable pile is hinged on the top wall of the shell, a retaining spring is arranged between the movable pile and the shell, the retaining spring maintains the state that the movable pile is abutted against the fixed pile, the hammer handle end of the inertial hammer is hinged on the side wall of the shell, the hammer head end of the inertial hammer is positioned above, and a magnet is arranged on the inner wall of the shell and adsorbs the hammer head end of the inertial hammer.
