Embodiment 1

[0035]Embodiment 1: The wireless communication module on the pressure sensor and the wireless communication module on the servo control unit are both connected to the external communication module on the controller. The external communication module on the controller is also connected to an intelligent device, and the pressure sensor passes through the The wireless communication module transmits the data measured by the pressure sensor to the controller, and the control system on the controller transmits the pressure data to the intention judgment module, and orders the intention judgment module to judge the intention through the pressure data, and the intention judgment module sends the judgment result The control system sends commands to the motion control module according to the judgment results of the intention judgment module. The motion control module sends commands to the servo control unit through the external communication module. There is a wireless communication modul...

Embodiment 2

[0036] Embodiment 2: After wearing, the controller starts to record the walking data of the user. The data includes the different degrees of effort of the left and right legs, the step distance of the legs, the step frequency, the body tilt and other information. After understanding the situation through the data, the user manually sets the degree of force of each booster of the exoskeleton-assisted robot to correct and To help users walk, the size of the left and right legs of the exoskeleton can be adjusted. For people with limited mobility, going up stairs is an environment that needs more assistance. When the legs move upward, the booster starts to exert force. After the movement stops, The power assist will also stop immediately, and at the same time, the external communication module of the exoskeleton robot can transmit the wearer's physical state and motion state data to the App in real time, so as to realize real-time monitoring of the user's physical signs.

Abstract

The invention discloses a booster-based hip and knee joint assisted external skeleton mechanism and belongs to the technical field of human body assistance. The booster-based hip and knee joint assisted external skeleton mechanism comprises a connecting external skeleton, a left limb external skeleton and a right limb external skeleton. The right limb external skeleton comprises a body width adjusting external skeleton, a hip joint booster, a thigh external skeleton, a knee joint booster, a shank external skeleton and a baffle plate. Leg lifting action of thighs and shanks can be assisted effectively by the assisted external skeleton mechanism designed by special employees with assisted power on hip and knee joints, so that sport consumption is alleviated and limb dyskinesia is relieved. Two hip joint pitching degrees of freedom and two knee joint pitching degrees of freedom are available. An ultrathin torque motor is used for driving. The mechanism can be attached to the body effectively, so that the mechanism is more compact in structure. Three training modes are available: a tracking mode through which the walking action is smoother, a symmetrical mode which guides a user to bend left and right legs during walking and a pedal mode which adjusts the center of gravity of the user.

Description

technical field [0001] The invention relates to an exoskeleton mechanism, in particular to a hip and knee joint booster exoskeleton mechanism based on a booster, which belongs to the technical field of human body boosting. Background technique [0002] Exoskeleton-assisted robots will improve the ability of the human body to walk and move, and reduce the work intensity of workers. Workers in the manufacturing and logistics industries are faced with a large number of mechanical operations of repeatedly carrying heavy objects every day. The waist, shoulders and other parts are under huge load pressure, which is prone to occupational diseases such as lumbar disc herniation, and at the same time, the work efficiency is not high. This solution provides an exoskeleton power-assisted robot, which is convenient for workers to use during work and reduces the weight on the body during work. [0003] The essence of an exoskeleton is a structure that can be fixed on the human body. It ...
