Problems solved by technology

At present, the lower extremity exoskeleton at home and abroad mainly has many parts, heavy weight, poor comfort and convenience, and cannot be put on and taken off quickly.
Then there is the danger of mechanical inertia in the rigid frame structure, and the form of rigid armor makes users lack psychological identity
Most importantly, the current rigid armored lower extremity exoskeleton is a load-bearing solution, which is mainly used to enhance the soldiers' weight-holding and load-bearing capacity, provide support for patients who are paralyzed or have lower limb diseases and cannot walk, and use equipment to drive patients to walk with lower limbs. Not suitable for elderly people with limited walking ability who need partial walking assistance

Embodiment Construction

[0037] 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.

[0038] Such as figure 1As shown, a flexible hip joint booster exoskeleton is mainly composed of a negative pressure control system 1 , a hip joint flexible booster component 2 and an inertial measurement unit component 3 .

[0039] The negative pressure control system 1 is the control center of the flexible hip-assisted exoskeleton, which is responsible for the data processing, drive control and negative pressure output control of the flexible hip-assisted exoskeleton. The joint flexible power assist component provides negative pressure input and negative pressure unloading, providing users with assisting hip joint movement consistent with gait.

[0040] The hip joint flexible assisting component 2 is the execution part of the hip joint flexible assisting of the left and right le...

Abstract

The invention discloses a flexible hip joint assistance exoskeleton. The flexible hip joint assistance exoskeleton comprises a negative pressure control system, a hip joint flexible assistance assembly and an inertia measuring unit assembly. The hip joint flexible assistance assembly adopts a negative pressure retraction elastomer driver as a hip joint assistance actuator; the negative pressure retraction elastomer driver can receive negative pressure input and unloading of the negative pressure control system; when negative pressure is input, linear displacement becomes shorter, and tension is obtained; when negative pressure is unloaded, in the process when the self-reaction state is recovered to the self-natural state, reverse linear displacement and restoring force are obtained. The negative pressure control system processes user gait data in real time, wherein the data is collected and fed back by the inertia measuring unit assembly, the negative pressure input and unloading process of the negative pressure retraction elastomer driver in the hip joint flexible assistance assembly is controlled in real time, assistance is provided for the hip joint of a user according to the gait rule in the walking process, and the walking assistance purpose is achieved.

Description

technical field [0001] The invention belongs to the technical field of flexible hip joint assisting exoskeleton and lower limb exoskeleton, and in particular relates to a flexible hip joint assisting exoskeleton. Background technique [0002] Since the beginning of the 21st century, the phenomenon of population aging in my country has become increasingly serious, and how to improve the quality of life of the elderly has received widespread attention from the society. Exoskeleton technology is a new type of human motion assisting robot technology. Applying exoskeleton technology to the field of walking aids for the elderly will enhance the lower limb exercise ability of the elderly, and has advantages in cost and practicability. It is a walking aid device for the elderly. new direction of research. [0003] At present, the lower extremity exoskeleton at home and abroad is mainly in the form of rigid frame armor structure, which can provide support and enhance exercise abilit...
