Intelligent weight-reducing gait trainer

Abstract

The invention discloses an intelligent weight-reducing gait trainer. The intelligent weight-reducing gait trainer comprises a track, a power supply system, a weight-reducing device, a walking device and a controller, wherein the power supply system is mounted in the track; the weight-reducing device is connected with the track through the walking device; the power supply system, the weight-reducing device and the walking device are all connected with the controller; and the weight-reducing device mainly comprises a winding drum motor, a screw winding drum, a screw shaft, a sliding rail, a pullrope, a fixed pulley, a movable pulley, a steering wheel, a first mounting plate, a second mounting plate and a fixing plate. The pitch of a wire groove in the screw winding drum is equal to the thread pitch of a thread of the screw shaft, and the screw winding drum moves axially along with rope outlet of the pull rope, so that the rope outlet direction of the pull rope is unchanged, the pull rope is prevented from being separated from the pulleys, and the overall size of the device is reduced; and meanwhile, the angle change of the pull rope is reduced, so that the measurement error of a force sensor is reduced, the weight-reducing precision is guaranteed, the reliability of the weight-reducing device is improved, and rehabilitation of a patient is facilitated.

Description

technical field [0001] The invention relates to rehabilitation medical equipment, in particular to an intelligent weight-reducing gait trainer. Background technique [0002] Intelligent weight loss trainer is an important equipment for patients to use for rehabilitation training. The current intelligent weight loss trainer mainly includes floor-type intelligent weight loss trainer and sky rail intelligent weight loss trainer. The sky rail intelligent weight loss training device is a sky rail intelligent weight loss training system installed on the ceiling. According to the change of the patient's center of gravity, the tension on the patient is adjusted to keep the weight of the patient's lower limbs constant. Although the current intelligent weight loss training device can provide rehabilitation training, it still has the following defects: due to the constant change of the outlet angle of the stay rope, in order to prevent the stay rope from falling off, the weight loss de...

AI Technical Summary

Problems solved by technology

Although the current intelligent weight loss training device can provide rehabilitation training, it still has the following defects: due to the constant change of the outlet angle of the stay rope, in order to prevent the stay rope from falling off, the weight loss device connected to the walking device needs to be of a longer size, so that The weight reduction device is large in size and heavy in weight, so the track needs to provide a large bearing capacity; at the same time, because the angle of the pull rope is constantly changing, it will affect the measurement accuracy of the force sensor, thereby affecting the accuracy of the weight reduction device, and then affecting Rehabilitation training effect; there is also easy slippage between the walking device and the track in the trainer, which affects the patient's rehabilitation training; the power supply system of the trainer is prone to leakage, and will interfere with the movement of the walking device, affecting rehabilitation training
