Problems solved by technology

[0003] The traditional quick power-off device is generally designed with fuse resistance, so that when there is an abnormal state in the car, such as a collision, the current in the car will increase, but the heat generated by the current is not enough to blow the fuse, so the current in the car Continue to increase and generate heat, causing fire in the car or electric shock accidents, which means that the response of the power-off device is insufficient

Embodiment Construction

[0027] The present invention will be further described below in conjunction with specific examples.

[0028] see figure 1 , a collision power-off protection device of the present invention includes a casing 1 and a safety piece 2 fixed in the casing 1, the casing 1 can be made of plastic material, and the two ends of the safety piece 2 extend out of the casing 1 A connecting end 21 is formed, and the connecting end 21 is connected to an external circuit to be protected. The insurance sheet 2 can be punched and formed by copper sheet or aluminum sheet.

[0029] see image 3 , also includes an ignition device 3 and an energy transmission part 4; the ignition device 3 is fixed on the first end of the housing 1; Break the fuse 2. After the ignition device 3 is detonated, there is enough energy to push the energy transfer member 4 for energy transfer. Under the action force and reaction force, the energy transfer member 4 is separated from the ignition device 3 and acts in two ...

Abstract

The invention discloses a collision outage protective device which comprises a shell and a safety lever which is fixed in the shell, wherein two ends of the safety lever stretch out of the shell and form connecting ends and the connecting ends connect external circuits to be protected. The collision outage protective device further comprises an ignition device and an energy transferring member, wherein the ignition device is fixed at a first end of the shell, the energy transferring member is arranged between the ignition device and the safety lever and is used for transferring energy of the ignition device and striking off the safety lever. The collision outage protective device has the advantages of being simple in structure, low in cost, quick in outage and safe and reliable.

Description

technical field [0001] The invention relates to a power-off protection device, in particular to a collision power-off protection device. Background technique [0002] With the development of science and technology, more and more electric power generation vehicles are widely used by people, such as electric vehicles, cars, trucks, buses, airplanes, helicopters, ships, etc. When these electric vehicles have accidents or short circuits, etc. It will cause the internal current of the car to be too large, which is prone to accidents such as fire or electric shock. Therefore, a device that can quickly cut off the power in an emergency can ensure the safety of passengers in the car and the safety of people in public places. [0003] The traditional quick power-off device is generally designed with fuse resistance, so that when there is an abnormal state in the car, such as a collision, the current in the car will increase, but the heat generated by the current is not enough to blow...
