Embodiment Construction

[0017] refer to Figure 1 to Figure 3 , a controllable magnetic hysteresis damping joint rehabilitation tool of the present invention, comprising the following components: a shell assembly, including a barrel-shaped shell 11, and a second part fixed on the outside of the bottom of the shell 11 for connecting one side of the joint. A handle 12, the so-called "barrel shape" refers to a hollow cylindrical structure known to those skilled in the art and has only one end plate. The position of the end plate is the bottom, and the other end is an opening. The body assembly includes a disc-shaped cover body 21, a second handle 22 fixed on the outer end surface of the cover body 21 for connecting the other side of the joint, and a concave stop is provided on the inner wall of the opening of the housing 11 , the outer wall of the cover body 21 is provided with a protruding notch matching with the notch notch, and the cover body 21 is supported on the notch notch of the housing 11 throu...

Abstract

The invention belongs to the mechanical transmission technical field in mechanical engineering and relates to a controllable hysteresis damping joint rehabilitation tool. The invention aims to solve the technical problem of the lack of reliable joints for providing external damping. The controllable hysteresis damping joint rehabilitation tool mainly comprises a shell and a cover body which are connected with two sides of a joint respectively; a sealed space is formed between the shell and the cover body and is filled with a magnetorheological fluid; a damping code disc is fixed onto the shellor the cover body; and when a joint rotates, the damping code disc rotates with the shell and the cover body, so that resistance is formed between the damping code disc and the magnetorheological fluid; a user can control the resistance through controlling the magnitude of current in a coil; since the change of the current affects the viscosity of the magnetorheological fluid, the resistance of the damping code disc and the magnetorheological fluid can be changed, and therefore, the stress state of the joint at different motion angles can be effectively improved, and potential hurt to the body of the user during a rehabilitation training process can be decreased. Thus, the controllable hysteresis damping joint rehabilitation tool is of great significance for prolonging the service time ofan astronaut.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission in mechanical engineering, in particular to a controllable hysteresis damping joint rehabilitation tool. Background technique [0002] Astronauts' work load is reduced in the weightless environment of space, which reduces muscle stress, leading to various adverse physiological effects such as muscle atrophy and bone loss. Long-term weightlessness will cause changes in various functions of the human body, and the most obvious physiological changes are the incremental decrease in calcium and changes in bone mass. During the recovery training process of astronauts, joint rehabilitation training is particularly important. Improper training methods can easily cause secondary injuries during the rehabilitation process. In order to improve the effect of joint rehabilitation training, controllable external damping can effectively improve the stress on joints at different motion angles, th...
