Wearable human gait mimicking lower limb rehabilitation walking aid device

Abstract

The invention provides a wearable human gait mimicking lower limb rehabilitation walking aid device. The device comprises a support frame, a waist part, a thigh pole, a shank pole, foot parts, and a drive module. The drive module is installed on the support frame and is fixed above the waist part, the top end of the thigh pole and the bottom of the waist part are connected in a hinged mode to form a hip joint, the lower end of the thigh pole and the upper end of the shank pole are connected in a hinged mode to form the knee joint, and the lower end of the shank pole and the foot part are connected in a hinged mode to form the ankle joint. The drive module through multiplexed outputs drives multiple flexible cables, each flexible cable as driven by the drive module one-by-one correspondingly pulls the thigh poles and the shank poles on both sides, and the completion of the movement during the gait cycle by the thigh poles, the shank poles and the foot parts is achieved. According to the wearable human gait mimicking lower limb rehabilitation walking aid device, the flexible cables are used to drive each joint part of the lower limbs to simulate human muscles and power the walking, with some flexibility and in line with the motion characteristics of the lower limbs of human bodies, and when the two lower limbs are driven, just two gear motors are used, and the energy consumption is low.

Description

technical field [0001] The invention relates to the technical field of rehabilitation walking aids, in particular to a wearable humanoid gait lower limb rehabilitation walking aid. Background technique [0002] According to relevant surveys, there are nearly 100,000 new patients with physical disability and spinal cord injury every year in my country, and with the serious aging, the body and various physiological functions of the elderly decline, stroke hemiplegia and lower limb injuries caused by traffic accidents lead to physical and mental health problems of patients. Severe injuries pose a serious burden to family members and society. The lower limb rehabilitation device is a rehabilitation device with wide application value. [0003] Rehabilitation walker device or rehabilitation robot is a product that combines modern technological progress and human rehabilitation medical needs. It belongs to the category of medical robots. Its main function is to help patients complet...

Problems solved by technology

However, these walking aids are often complex in structure, and the control system is expensive, resulting in extremely high prices.

[0005] The patent number is 201310419611.5, and the technical solution disclosed in the patent document named "Human-like gait lower limb rehabilitation walking aid device" uses a linkage mechanism to simulate the normal walking motion of a human being. Its structure is simple, but it does not have flexibility and impact. The force is large, the adjustment is inconvenient, and it cannot fit the user's body well

Patent No. 201310689890.7, in the patent document titled "Wearable Lower Limb Rehabilitation Training Device", drives the knee joint and hip joint to move respectively through two sets of linkage mechanisms. The structure is relatively simple, but it is also not flexible and requires many a motor, the coordination of the knee and hip joints cannot be guaranteed

Neither can rehabilitate individual joints
