Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific examples of implementation, but not as a limitation of the present invention.

[0041] Such as figure 1 As shown, a flexible walking exoskeleton is mainly composed of a portable control box 1, a wearable flexible actuator 2, and the like. The portable control box 1 is the control and power output part of the flexible walking exoskeleton; the wearable flexible actuator 2 is a flexible power-assisted part installed on the knee joints of the user's left and right legs.

[0042] Such as Figure 1-2 As shown, the portable control box 1 mainly includes a control box installation shell 101, a protective cover 102, a micro air pump 103, an air circuit installation plate 104, a five-way adapter 105, a three-way solenoid valve A 106, and a three-way solenoid valve B 107, three-way solenoid valve C 108, three-way solenoid valve D 109, drive and control module 110, lit...

Abstract

The invention discloses a flexible walking-aid exoskeleton. The exoskeleton includes a portable control box, wearable flexible actuators and the like. A wearable inertial measurement unit module is used for acquiring a lower-limb movement picture in real time, and a core signal source is provided for a drive and control module. Under the excitation of the signal source, the drive and control module is used for understanding, judgment, decision making and anomaly detection of the human-body lower-limb movement picture, the output flow of a micro inflatable pump is controlled in real time, and asolenoid valve component is controlled for switching of air channels. Based on the real-time movement state of the lower limbs of a user, pressure control is conducted on corresponding air bags of the wearable flexible actuators on the left leg and the right leg, in the walking process, torque for aiding the knee joint in bending and stretching is provided for the left leg and the right leg, andthe purpose of providing flexible walking aid for the elderly with knee-joint sport injuries and weak walking ability is achieved.

Description

technical field [0001] The invention belongs to the technical field of flexible exoskeleton robots, lower limb exoskeletons and flexible actuators, and particularly relates to a flexible walking aid exoskeleton. Background technique [0002] There are more than 220 million elderly people with weak walking ability in my country. Due to the decline of physiological functions, there are phenomena such as reduced range of motion of joints, decreased ligament elasticity and absolute muscle strength. They need walking assistance to improve their quality of life. In addition, there are more than 130 million patients with knee arthritis in my country. Knee arthritis is the No. 2 killer of people over 50 years old who are incapacitated, second only to cardiovascular diseases, and the cost is high, with an average annual direct cost of more than 7,000 yuan. A suitable knee exoskeleton can enhance the leg muscle strength of the elderly with weak walking ability, knee joint injury and k...
