Vehicle self-saving expander

Abstract

The invention relates to a vehicle self-saving expander comprising a supporting mechanism and a power mechanism, wherein the supporting mechanism is used for expanding a deformed vehicle body; the power mechanism is used for supplying expanded power for the supporting mechanism; the power mechanism comprises a portable air pump and a storage battery, wherein the storage battery is used for supplying electricity to the air pump; the lower end of the supporting mechanism is arranged in a cylinder body in a sliding mode, an air bag is arranged between the bottom surface of the supporting mechanism and the bottom surface of the cylinder body, the air pump arranged in the power mechanism inflates the air bag through an air transporting pipe; and the supporting mechanism comprises supporting blocks, wherein the supporting blocks are used for supporting the deformed vehicle body and are telescopically arranged at the upper end of the supporting mechanism; and an expander stroke comprises a spiral driving stroke and an air-bag pulling stroke. The vehicle self-saving expander has the advantages of larger stroke, stable power-source support, small volume, light weight, simple manufacturing process, convenient assembly and disassembly and lower cost.

Description

technical field [0001] The invention relates to a rescue device used after a car accident occurs, in particular to an expander for self-rescue of people in the car. Background technique [0002] Cars are one of the most important means of transportation. Traffic accidents are often caused by drivers’ illegal driving, slippery roads and pedestrians’ failure to obey traffic rules during driving, and major traffic accidents are likely to cause the occupants of the car to be arrested. The deformed seat or frame is pressed down. In this case, if the occupants of the car cannot escape in a short time, it will not only delay the timing of medical treatment, but also cause secondary injuries. Therefore, there is a need for a car accident when the self-rescue device. [0003] At present, the existing self-rescue devices used for automobile accidents generally have certain defects, such as a commonly used airbag jack, which includes an airbag and a power source. The power source is h...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned deficiencies in the prior art, the main purpose of the present invention is to solve the problem that the stroke of the support mechanism of the self-rescue device currently used in automobiles is too small to expand a large enough escape space, and further solve the problem that the traditional expander The size and weight are too large to be inconvenient to use, as well as the lack of power source support, and a vehicle self-rescue expander with a larger stroke, smaller size and weight, and sufficient power source support is provided
