Embodiment Construction

[0015] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0016] combine Figure 1-5 , the whole mechanism includes a front foot plate part, a rear foot plate part, a support column, a motor transmission part, and a signal detection part. The front foot plate is welded in two parts, and the bottom of the front foot plate 2 is welded with a detection block 19, which can change its output signal potential when the distance from the proximity switch 18 is less than a certain range. The rope column 1 is fixed on the front end of the front foot plate, and its left end protrudes and has grooves for connecting ropes. A spring 17 is connected between the rope column 1 and the top plate 15, which provides pre-tightening force and power for the front foot board to return to the motion for the rope. The front foot plate periphery is fixed with protective frame 3, sticks out the front foot plate to prevent the patient's pin. The ...

Abstract

The invention aims to provide a gait rehabilitation robot footrest device with metatarsal joints, comprising a front foot plate, a rear foot plate, a motor and a cord, wherein the motor comprises an ankle motor, a metatarsal motor, encoders, an approach switch, a supporting plate arranged at one side of the rear foot plate, a supporting head arranged on the supporting plate, a large pulley arranged on the metatarsal motor, a cord post arranged below the front foot plate and a spring connected with the cord post and the ankle motor; both the ankle motor and the metatarsal motor are arranged below the rear foot plate; the ankle motor is connected with the rear foot plate through a connecting block fixed to the bottom of the rear foot plate; the encoders are respectively arranged at high-speed ends of the ankle motor and the metatarsal motor, and the other end of the metatarsal motor is provided with the large pulley; and the cord rounds the cord post, the supporting head and the large pulley. The invention more conforms to the real motion state of feet, achieves a better rehabilitation training effect and is suitable for various crowds, and the training of various motion modes can be finished through changing gait data.

Description

technical field [0001] The invention relates to a medical rehabilitation robot device. Background technique [0002] In recent years, rehabilitation robots have shown more and more advantages in scientific and effective rehabilitation training for patients. Early rehabilitation training can not only maintain the joint range of motion and prevent joint contracture, but also significantly improve the final recovery of the patient's motor function. Among them, passive movement training is a basic method in the rehabilitation training therapy of limb motor function. [0003] The existing gait rehabilitation robots generally realize the simulation of human gait through the swing of thigh and calf and the rotation of ankle, ignoring the role of human foot metatarsal joints in gait. A perfect set of gaits must allow the patient to walk easily and for extended periods of time. The metatarsal joint plays a very important role in the stance phase, the time when the lower extremity ...
