Problems solved by technology

[0002] The knee joint is the largest joint in the human body with the most complex structure and many chances of injury. Traditional prosthetics, in the prior art, passive knee prosthetics mainly simulate the rotation function of the joint through mechanical devices. The rotation damping cannot be adjusted or can only Manually set a limited number of damping states, so when adjusting the damping, most of the pace is adjusted by manually adjusting the dampi

Abstract

The invention discloses a bionic lower limb mechanism which comprises a support. The connecting piece is rotatably arranged on the bracket, and the connecting piece is connected with the artificial thigh; the damping device is arranged below the connecting piece and comprises a damping piece and a connecting frame, the end, close to the support, of the damping piece is rotationally connected with the support, a piston with the adjustable diameter is arranged in the damping piece and is in transmission connection with the connecting piece, the connecting frame is fixed to the outer wall of the damping piece, and the end, away from the damping piece, of the connecting frame is connected with the artificial shank; and the control piece is arranged outside the damping device and used for controlling the diameter of the piston. By means of the damping device, a user can conduct self-adaptive intelligent adjustment on rigidity damping of the damping device conveniently, then the user can adjust the step speed conveniently, and the movement flexibility and environment adaptability of the damping device are improved.

Description

technical field [0001] The invention relates to the technical field of artificial limbs, in particular to a bionic lower limb mechanism. Background technique [0002] The knee joint is the largest joint in the human body with the most complex structure and more chances of injury. Traditional prosthetics, in the prior art, passive knee joint prostheses mainly simulate the rotation function of the joint through mechanical devices, and the rotation damping is not adjustable or can only be used. Manually set a limited number of damping states, so when adjusting the damping, most of the steps are adjusted by manually adjusting the damping of liquid or gas. However, when performing manual adjustment, it is necessary to manually adjust the damping device, which is not only cumbersome. At the same time, due to the user's own reasons, most of them need the assistance of others when adjusting. This process makes the adjustment of the damping difficult and the use effect is poor. There...
