Problems solved by technology

Existing power-assisted mechanical legs (such as Chinese patent application 200410069529.5) have defects in stability, and are difficult to control during use. Moreover, due to the oil pressure system, the structure is relatively complicated, the weight is also relatively large, and it is cumbersome to use. Walking is more strenuous
In order to achieve better results in use of the power-assisted mechanical legs of this structure, the air valve of the oil cylinder needs to be continuously adjusted. Under different environments and conditions, the use of mechanical legs is more cumbersome.

Abstract

The invention relates to an elastic booster, in particular to a run and jump assistant mechanical leg. The structure of the run and jump assistant mechanical leg is as follows: the run and jump assistant mechanical leg comprises an upper power-assisted leg and a lower power-assisted leg which are connected with each other through a pin shaft, wherein the lower end of the lower power-assisted leg is connected with a tail margin; the upper power-assisted leg and the lower power-assisted leg are provided with three leggings together; the middle part of the upper power-assisted leg is connected with an upper strut through a pin shaft; the lower end of the upper strut is connected with a lower strut through a pin shaft and the lower end of the lower strut is connected with a tension spring which is arranged on the lower power-assisted leg; and lower middle sections of the upper power-assisted leg and the lower power-assisted leg are respectively provided with long openings. The elastic booster has a simple structure and light weight, is easy to control and convenient to use, and is particularly suitable to be used by cross-country people.

Description

technical field [0001] The invention relates to an elastic power-assisted device, in particular to a mechanical leg for running and jumping. Background technique [0002] The run-up and jump-up mechanical legs are mainly used for single-person off-road use. They are directly installed on the human legs to provide assistance when people are walking. Existing power-assisted mechanical legs (such as Chinese patent application 200410069529.5) have defects in stability, and are difficult to control during use. Moreover, due to the oil pressure system, the structure is relatively complicated, the weight is also relatively large, and it is cumbersome to use. Walking is more laborious. In order to achieve better results in use of the power-assisted mechanical legs of this structure, the air valve of the oil cylinder needs to be continuously adjusted. Under different environments and conditions, the use of the mechanical legs is relatively cumbersome. Contents of the invention ...
