Ankle rehabilitation robot

Abstract

The invention discloses an ankle joint rehabilitation robot, comprising a right drive unit, a left drive unit, a bottom drive unit, a triangular support frame, a sole support plate, a damping unit and a bottom plate, wherein the drive unit and the left drive unit are located on the sole of the foot On both sides of the support plate, the right drive unit and the left drive unit are located on both sides of the sole support plate in a lever structure, and the bottom drive unit is located between the right drive unit, the left drive unit, the triangular support frame and the sole support plate. On the bottom plate at the bottom end, the end of the damping unit is connected with one end of the sole support plate. The present invention uses a linear motor to realize the driving technology of complex curved trajectory, so that the linear motors on both sides of the ankle joint drive the soles of the human body to complete flexion, extension and inversion, and the linear motor at the bottom completes the internal and external rotation of the ankle joint. A buffer spring is installed to improve the wearer's comfort, and it has the characteristics of small size, light weight, etc., and is easy to carry.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an ankle joint rehabilitation robot. Background technique [0002] The ankle joint is a three-degree-of-freedom joint with six movements of flexion and extension, inversion, and internal and external rotation. Most assisted rehabilitation robots only focus on a single action of flexion and extension, that is, only one degree of freedom, and cannot achieve comprehensive assisted rehabilitation. [0003] The ankle joint plays an important role in the whole human body to sense the ground state, adjust the balance, and buffer the ground reaction force. With the increase of age, muscle atrophy, inflammation and pain caused by joint diseases, and muscle contracture caused by stroke are gradually produced. The ankle joint directly affects normal walking, and there are still many deficiencies in the current joint rehabilitation treatment in my country: [0004] 1. Mainly rely on the hospi...

AI Technical Summary

Problems solved by technology

[0004] 1. Mainly rely on the rehabilitation physiotherapist in the hospital, not only there are many rehabilitation training items, but also the degree of rehabilitation varies depending on the personal judgment and level of the doctor;

[0005] 2. There is a shortage of rehabilitation physicians in my country, the number of patients is huge, and the proportion is seriously unbalanced. Patients may lose the golden recovery time during the waiting time for appointments, and the recovery cycle will also increase as a result, resulting in slow recovery and low efficiency;

[0006] 3. The equipment used in the hospital is also expensive, and the function is relatively single. Different rehabilitation stages need to use different equipment for physical therapy, which is a big economic burden for the hospital and the individual patients
