Self-gravity auxiliary walking device

Abstract

The invention relates to the field of auxiliary walking, and discloses a self-gravity exoskeleton auxiliary walking device. According to the device, the pressure of a human body on the ground can be converted into supporting and lifting effects on knee joints and thighs. According to the device, a person steps on the pedal to generate pressure, so that the shape of the bottom structure is changed, the sliding rail at the bottom of the pedal is driven to move to generate pulling force on the rope in the device, and then the supporting arm is pulled to rotate along the rotating shaft to apply supporting force to thighs and knee joints. The invention has the advantages of low cost, no battery endurance problem, environmental protection and the like, and can effectively solve the defects in the prior art. The device comprises the implementation steps that a person steps on the pedal, the bottom connecting structure is stressed to generate structural change, and the rope pulls the supporting arm to stably rotate by a proper angle along the rotating shaft.

Description

Technical Field

[0001] The present invention relates to the field of assisted walking, and in particular to an assisted walking device capable of converting the pressure of a human body on the ground into supporting and lifting effects on the thigh. Background Art

[0002] Currently, there are some common drawbacks in walking-assistance devices, such as the widespread use of motors, which results in excessive weight, high cost, and battery life issues. This device can effectively address these issues. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a method of using one's own gravity to assist walking.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] The walking-assist device of the present invention generates pressure when a person steps on a pedal, causing the bottom structure to change shape. This drives the slide rail at the bottom of the pedal to move, which in turn pulls the rope in the device downward. This pulls the support arm upward along the axis to lift the thigh, applying support force to the thigh and reducing the burden on the knee joint. Its characteristic is that it converts the pressure of the human body on the ground into support and lifting effect on the thigh.

[0006] The present invention has the following beneficial effects:

[0007] 1. Low cost, the whole set of work can be completed with only mechanical structure;

[0008] 2. No battery life issues, can be used continuously;

[0009] 3. Use its own gravity to convert into power for exoskeleton-assisted walking, which is green and environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is the overall structure diagram of the device. The triangular shape of the bottom connecting structure (1) in the figure is used to produce structural changes when it is subjected to pressure, sliding on the slide rail, thereby generating tension on the rope;

[0011] The use of the movable pulley in the rope shortening device (2) increases the rotation angle of the support arm at the thigh and shortens the displacement of the traction rope, so that the folding distance of the device during assisted walking meets the needs of the human body;

[0012] The use of the semicircular block (3) at the joint connection is used to enable the rope-traction thigh-side device to exert force stably and evenly when rotating along the axis. DETAILED DESCRIPTION

[0013] The auxiliary walking device of the present invention can be implemented according to the following steps:

[0014] When a person steps on the pedal, pressure is generated, causing the bottom connection structure (1) to change shape, driving the slide rail to slide, thereby generating tension on the rope.

[0015] The rope cleverly drives the rope-traction thigh-side device to rotate along the axis to a suitable angle through the rope shortening device (2), and the semicircular block (3) at the joint connection can exert a stable supporting force on the thigh, thereby effectively reducing the burden on the knee joint and achieving the purpose of assisting walking.

Claims

1. A walking aid device that generates pressure when a person steps on a pedal, causing the bottom structure to change shape. This drives the slide rail at the bottom of the pedal to move, which in turn generates a downward pull on the rope in the device, thereby pulling the support arm upward along the axis to lift the leg, exerting support force on the thigh and reducing the burden on the knee joint. Its characteristics are: Convert the pressure of the human body on the ground into support and lifting effect on the thighs.

2. The walking assist device according to claim 1, wherein: The triangular shape of the bottom connecting structure (1) is used to slide on the slide rail when the bottom connecting structure (1) is subjected to force and undergoes structural changes, thereby generating tension on the rope.

3. The walking assist device according to claim 1, wherein: The use of the movable pulley in the rope shortening device (2) is used to reduce the length change of the upper rope so that the folding distance of the device during the assisting walking process meets the needs of the human body.

4. The walking assist device according to claim 1, wherein: The use of the semicircular block (3) at the joint connection is used to enable the rope-traction thigh-side device to exert force stably and evenly when rotating along the axis.
