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 comprises a detection device, an adjusting module, a control end, a Bluetooth module and a display terminal which are located on a leg fixing piece, wherein the control end controls an electric hydraulic pump through a PID algorithm; the detection device comprises a vibrator and a sensor, the vibrator sends out vibration waves to the legs of a human body, the sensor senses the vibration waves emitted from the human body and sends the detected vibration waves to the adjusting module; the adjusting module automatically adjusts the control end according to the frequency of the vibration waves and a time change curve; and the control end sends adjustment data to the display terminal through the Bluetooth module. According to the system, a closed-loop control algorithm is adopted, the problem of large errors of a hydraulic push rod is relieved, the control end is adjusted according to skeleton data detected by the detection module, discomfort of thighs during mechanical movement can be effectively reduced, and data visualization is achieved through the display terminal; and the data record of assisted walking is displayed through an APP.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an algorithm-controlled hydraulic oil pump knee exoskeleton device and system. Background technique [0002] For the independent action assistance of the weak legs and feet, there are two main technical solutions: elastic knee pads and motor leg assist devices. [0003] Elastic knee pads: 1. It takes more energy to compress, and it cannot solve the root cause of the weakness of the legs. 2. It is inconvenient to sit down when wearing it. [0004] Motor assist: 1. The force is small and the effect is very limited. 2. Energy conversion efficiency is low. 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 make appropriate adjustments. Contents of the invention [0006] In order to at least solve o...
