Embodiment Construction
[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the invention, not to limit the invention.
[0014] like figure 2 Shown is an embodiment of the present invention, a quick power-off device, including a cylinder 7, the cylinder 7 can be cylindrical or square in cross-section, and can also be oval or other shapes. The shape of the cylinder does not limit the present invention, and the cylinder 7 includes a cylinder wall 71 and a cavity 72. The cross section of the cavity 72 can be a non-rotating shape. In this embodiment, a square is used. One side of cylinder 7, namely figure 2 In the left side, the cavity 72 of the barrel 7 is sealed by the sealing member 3, and the input end 1 and the output end 2 are...

The invention discloses a rapid power-down device, relates to the field of emergency protection and aims to solve the technical problem of poor control of the tightness of a wedge in a rapid power-down device in the prior art. The invention provides the rapid power-down device, wherein the device is provided with a cylinder with a hollow cavity, an input end, an output end, a power source, a first terminal, a second terminal and a punch head; the input end and the output end are arranged on one side of the cylinder and connected with an element to be switched off; the power source is arrangedon the other side of the cylinder and connected with an emergency signal generating device; the first terminal is arranged in the hollow cavity and electrically connected with the input end; the second terminal is arranged in the hollow cavity, elastically propped against the first terminal and electrically connected with the output end; the punch head is embedded in the hollow cavity of the cylinder to receive the power of the power source and punch the first terminal and the second terminal; and the punch head is an insulating member. By using the scheme, the power-down operation can be realized by only punching the first terminal and the second terminal which are propped against each other through the punch head and has no substantial requirement on the tightness of the punch head, so that the consistency of the product can be ensured.
Description
【Technical field】 [0001] The invention relates to an emergency protection device, in particular to a quick power-off device. 【Background technique】 [0002] The quick power-off device is a safety device installed on the vehicle. When the vehicle collides, rolls over and other accidents, the quick power-off device can act in a very short time to complete the power-off operation, so as to cut off the power supply, engine The work of power failure and flameout can effectively prevent possible vehicle short-circuit fire, deflagration, short-circuit explosion of the power battery, and secondary injury to passengers and passers-by caused by the engine continuing to run after a vehicle accident. [0003] like figure 1 Shown is the existing quick power-off device, which uses a wedge 20 that plays a conductive role to connect in the circuit. When an emergency occurs, the power source generates gas, and the wedge 20 is quickly pushed away, so that the wedge 20 is connected. The disc...
