Description

Technical Field

[0001] The present invention relates to a wearable gait guidance device placed at the waist, belonging to the technical field of rehabilitation equipment, and in particular to a modular gait guidance device with a projection function and combined with mechanical programmable angle scanning. Background Art

[0002] As people pay more and more attention to their health, the demand for gait guidance and rehabilitation equipment is growing. Rehabilitation patients, children, fitness people and the elderly all have a need for gait guidance to improve their gait posture.

[0003] At present, in addition to some products on the market, there are many patents involving design solutions in related fields, but they all still have some areas to be improved or optimized. For example:

[0004] 1. The patent "A gait guidance device for shoes, soles and shoes including the device" (Chinese patent application 202110848996.1) discloses a gait guidance device for shoes and matching soles and business shoes. By embedding an elastic support beam in the sole and a transverse guide rod biased to the outside of the support beam, combined with the transverse groove, longitudinal groove, oblique groove and S-shaped groove design of the sole, a method of gait guidance is performed by using structural deformation to absorb the impact of walking inertia and guide the center of gravity to return to the center line. However, this patent is more intended to complete gait correction through footwear in a passive form, and does not involve electronic control and projection. Its guidance method is not intuitive enough. Users need to be distracted to feel the sensation of the sole of the foot, and cannot use vision to directly guide leg movements. Moreover, this solution cannot be conveniently used in the field of rehabilitation.

[0005] 2. The patented "A Lower Limb Assisted Mobility Rehabilitation Device" (Chinese patent application 202310393743.9) utilizes a U-shaped omnidirectional mobile chassis equipped with four sets of MY3 omnidirectional wheels with adaptive suspension to achieve multidirectional mobility. It incorporates a cam-and-rocker mechanism to simulate the bionic motion trajectory of the hip and knee joints, and utilizes an adjustable support frame and damping buffer system to stabilize the patient's position and achieve gait guidance. This active gait guidance device suffers from complex and high costs, making it difficult to use in teaching areas such as running guidance and children's walking training.

[0006] 3. The patent "A wearable gait guide for Parkinson's patients" (Chinese patent application CN201920433704.6) uses straps to secure a base to the head, waist, or knees. The light-emitting module on the base projects green / blue parallel stripes of light to form dynamic stripes. An angle adjustment component adjusts the projection distance of the light spot, and an integrated speaker provides rhythmic audio stimulation, utilizing multimodal sensory stimulation to improve freezing gait. This solution's mechanical angle adjustment device is prone to performance degradation, and the fixed voice control module is costly and unfriendly to the hearing-impaired.

[0007] Therefore, the technical field urgently needs a gait guiding wearable device which is suitable for various target groups, simple in structure, small in size, low in cost and good in auxiliary effect in addition to the gait guiding function for rehabilitation needs in the above-mentioned patents.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technical personnel in this field without making creative efforts are within the scope of protection of this invention.

[0037] The projection module 2 has two sets of symmetrically arranged optical systems 21 to guide the user's left and right gaits respectively. The optical system 21 includes a light source 211, a right-angle reflection prism 212 and a light spot generating lens 213.
