Virtual reality walking device having stride length adjusting function

Abstract

The present invention provides a virtual reality walking device comprising: a flywheel which is driven by a foot step part (110) so as to be rotated; a link unit (130) which is provided between the flywheel and the foot step part and provides a walking trajectory to the foot step part; a head-mounted display which provides a virtual reality image; a disk which is attached to the outer circumference of the flywheel so as to integrally rotate with the flywheel, and has grooves (158a) formed at predetermined intervals; a sensor which senses the grooves of the rotating disk; an electric step motor which is attached to the flywheel; a crank of which one end is connected to the electric step motor such that the length thereof can be adjusted, and the other end is connected to the link unit; and a controller which calculates a walking speed on the basis of the number of grooves sensed by the sensor, and is linked with lower-limb walking of a character in the virtual reality image on the basis of the walking speed so as to control the length of the crank, and thus adjusts the stride length of the foot step 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
