A wearable lower limb assist device with built-in air pressure

Abstract

The invention relates to a built-in air pressure type wearable lower limb auxiliary device. The device comprises an air push rod (10), fixing parts and a connection rod (8), wherein the air push rod (10) comprises a push rod cavity (2) with built-in air pressure, a push rod piston (1) and a push rod body (3), the push rod piston (1) is arranged in the push rod cavity (2) and can move along the inner wall of the push rod piston, and one side of the push rod piston (1) is further connected with the push rod body (3) penetrating through the push rod cavity (2) in a sealed mode; the fixing parts comprise the thigh fixing part (9) and the shank fixing part (4), and the thigh fixing part (9) is movably connected with one end of the push rod cavity (2); the two ends of the connecting rod (8) are movably connected with the cavity wall of the push rod cavity (2) and the shank fixing part (4) respectively. Compared with the prior art, the device has the advantages of being simple in structure, low in cost, diverse in function and the like.

Description

technical field [0001] The invention relates to a lower limb assisting device, in particular to a built-in pneumatic wearable lower limb assisting device. Background technique [0002] Wearable power-assisted device is a relatively new research field in recent years, it can help people expand the movement ability of their limbs and reduce the burden of heavy objects on people. At present, the existing wearable power-assisted devices in the world mainly include the HAL series lower extremity exoskeleton of the University of Tsukuba in Japan, the EHPA research project of DARPA in the United States, and the C-LEG intelligent bionic leg of Ottobock in Germany. [0003] However, traditional wearable power-assisted devices that require external power have the following disadvantages: [0004] 1. The entire device includes mechanical devices, power devices and control devices that can be worn on various parts of the human body, as well as various sensors that detect human body mov...

AI Technical Summary

Problems solved by technology

[0004] 1. The whole device includes mechanical devices, power devices and control devices that can be worn on various parts of the human body, as well as various sensors for detecting human motion information, resulting in excessive self-weight, which reduces its portability to a certain extent

[0005] 2. The high cost of equipment such as sensors and high-power motors reduces the practicability and popularity of the entire device
