Virtual reality walking device with stride adjustment

Abstract

The invention provides a walking device for virtual reality, which is characterized in that it includes: a flywheel driven to rotate by the pedal part (110); a link unit (130), arranged between the pedal part and the flywheel, providing walking to the pedal part a track; a head-mounted display for providing a virtual reality image; a disk attached to the outer periphery of the above-mentioned flywheel for integral rotation and having grooves (158a) formed at predetermined intervals; a sensor for detecting the rotation of the above-mentioned disk groove; an electric stepping motor attached to the above-mentioned flywheel; a crank whose one end is connected to the above-mentioned electric stepping motor to be able to adjust the length, and the other end is connected to the above-mentioned link unit; and a control part according to the number of grooves detected by the sensor Calculating the walking speed, based on this, adjusting the length of the crank in linkage with the walking of the lower limbs of the character in the virtual reality image, to adjust the stride length of the pedal part.

Description

technical field [0001] The invention relates to a walking rehabilitation device, which has the function of providing virtual reality and adjusting the stride according to the role in the virtual reality. Specifically, as the user's walking speed increases, the stride increases proportionally, and these variables (speed, step Frame) is reflected in the motion of the character in virtual reality (VR), allowing the user's motion to align with that of the character, allowing them to focus on walking rehabilitation. Background technique [0002] Generally, walking rehabilitation equipment is used for rehabilitation treatment of patients with mobility impairment due to lower limb paralysis or muscle weakness. [0003] Due to aging, accidents, stress and other factors, the number of disabled people with brain lesions and patients with lower limb joint surgery is increasing rapidly. For them, the most needed and effective rehabilitation may be walking related training. In walking t...

Problems solved by technology

[0005] However, the existing technology is based on the walking rehabilitation equipment with 4-joint and 5-joint links. People can only change the stride adjustment manually, and do not have the function of naturally adjusting the stride according to the acceleration of walking speed. Based on 4 The traditional end-effect walking rehabilitation equipment linked by sections and 5 sections does not have a virtual reality system linked to the walking mode provided by the driving department
