An algorithm-controlled hydraulic oil pump knee exoskeleton device and system

Abstract

The invention discloses an algorithm-controlled hydraulic oil pump knee exoskeleton device and system. The system includes a detection device located on the leg fixing piece, an adjustment module, a control terminal, a Bluetooth module, and a display terminal. The control terminal uses a PID algorithm to control the electric hydraulic pump. , the detection device includes a vibrator and a sensor, the vibrator sends vibration waves to the legs of the human body, the sensor senses the vibration waves emitted from the human body, and sends the detected vibration waves to the adjustment module, and the adjustment module The frequency and time curves of the control terminal are automatically adjusted, and the control terminal sends the adjustment data to the display terminal through the Bluetooth module. The system of the present invention adopts a closed-loop control algorithm to alleviate the problem of large errors in the hydraulic push rod, and adjusts the control end according to the bone data detected by the detection module, which can effectively reduce the discomfort of the thigh during mechanical movement, and visualize the data through the display terminal . The data record of assisting walking is displayed through the APP.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, particularly to an algorithmically controlled hydraulic oil pump knee exoskeleton apparatus and system. Background [0002] For independent mobility assistance for people with weak legs and feet, there are two main technical solutions: elastic knee pads and motor leg assist devices. [0003] Elastic knee pads: 1. Compression requires more physical exertion, and cannot solve the problem of weak legs from the root. 2. When wearing, it is not convenient to sit down. [0004] Motor boost: 1. The force is small, and the effect is very limited. 2. Low energy conversion efficiency. 3. Fever is large. 4. Usually requires an oversized 18650 battery pack, placed at the waist, not easy to move. [0005] And in the transmission process is easy to strain the bone, can not be adjusted moderately. Contents of the Invention [0006] In order to solve at least or partially solve the above problems, an...

AI Technical Summary

Problems solved by technology

[0003] Elastic knee pads: 1. It takes more energy to compress, and cannot solve the root cause of the weakness of the legs

2. When wearing it, it is inconvenient to sit down

[0004] Motor assist: 1. The force is small and the effect is very limited

2. Low energy conversion efficiency

3. High fever

4. Usually requires a super large 18650 battery pack, which is placed on the waist and is not easy to move

[0005] And it is easy to strain the bones during the transmission process, and it is impossible to adjust appropriately
