A three-degree-of-freedom parallel training device for ankle joint rehabilitation comprises a support, a parallel mechanism and a treading device, the parallel mechanism comprises four driving branch chains and a constraint branch chain, the parallel mechanism belongs to the category of redundant drive parallel mechanisms, the driving branch chains are connected with a fixed platform through hooke joints and connected with a movable platform through spherical hinges, and the constraint branch chains are connected with the fixed platform through spherical hinges. Each constraint branch chain comprises a height-adjustable push rod and three connecting rods, the push rods are fixedly connected with the fixed platform through screws, the connecting rods are connected with the movable platform and the connecting rods through revolute pairs, and the axis spaces of the three revolute pairs are converged at the motion center of the ankle joint; the support is fixedly connected with the motor through a screw, and an output shaft of the motor is connected with the constraint branch chain. The treading device comprises a pressure sensor and a pedal and is arranged on the movable platform. According to the ankle rehabilitation training device, the rehabilitation effect of the ankle rehabilitation training device is improved, the flexibility and applicability of the ankle rehabilitation training device are improved through the height-adjustable push rod and the redundant drive parallel mechanism, and the use comfort of a rehabilitative person is improved.
Description
technical field [0001] The invention relates to the field of ankle rehabilitation, in particular to a three-degree-of-freedom parallel training device with high flexibility and high adaptability for ankle joint rehabilitation. [0002] technical background [0003] In daily life, ankle sprain is the most common injury. This kind of injury can occur in both the elderly and children. The treatment of ankle is a long-term process. There are many treatment methods. You can try sports recovery by yourself. It is slow, the recovery effect is not good and it is easy to cause secondary sprains, and ankle rehabilitation institutions can also be used for treatment. Currently, ankle rehabilitation institutions on the market can achieve the purpose of treating ankles, but they have low flexibility and low adaptability. The scientific structure and existing technical means should ensure that the rehabilitation mechanism has high stability and avoid secondary sprains during the rehabilitat...
