[0019] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0021] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Please see Figures 1 to 2This utility model provides a walking aid device in one embodiment, comprising a walking aid body, wherein the walking aid body includes a support plate that conforms to the back of the human body. The support plate is made of carbon fiber, which is characterized by strength, high quality, and light weight. A waist belt 1 is provided on one side of the support plate to fix the support plate to one side of the human back. In this embodiment, to avoid the support plate directly contacting the human body and causing discomfort due to friction on the skin during walking, the width of the waist belt 1 is set to be greater than the width of the support plate. This setting also helps to increase the area of ​​waist support provided by the waist belt 1. An assisting mechanism 2 is fixedly provided in the middle part of the outer side of the support plate. The assisting mechanism 2 includes a housing 21 and an assisting component. The assisting component includes two motors and a drive component for driving and controlling the operation of the motors. Lifting rods 3 are rotatably connected to both sides of the assisting mechanism 2. One end of the lifting rod 3 is connected to a motor located inside the assisting mechanism 2 via gears. In this embodiment, the motor is a servo motor. The lifting rod 3 extends from the end of the lifting rod 3 away from the assisting mechanism 2 to the front end of the thigh on the same side. The structure features an arc shape, with a thigh fixing component connected to the lifting link 3 near the thigh. The thigh fixing component includes a connecting part 4 and at least one fixing part 5 for securing the connecting part 4 to the thigh. Further, the fixing part 5 includes a fixing plate 52 and a strap 51 for securing the fixing plate 52 to the thigh. The fixing plate 52 and the strap 51 are fixedly connected. In this embodiment, two fixing parts 5 are provided, and the fixing plate 52 portions of the two fixing parts 5 are interconnected to form a single structure. This design allows for a more secure connection with the thigh. The thigh binding is connected to the fixing plate 52 of the two fixing parts 5. One end of the connecting part 4 is fixedly connected to one end of the lifting link 3. When the device is working, the lifting link 3 is driven to rotate by the servo motor, which drives the connecting part 4 in the thigh fixing assembly to lift the fixing part 5, thereby achieving the effect of lifting the thigh and reducing the force of lifting the legs when the human body moves, thus helping the human body to walk for a long time. In addition, the support plate and waist belt 1 can also relieve the lower back pain caused by prolonged standing after walking for a long time, and play a certain role in lower back support.

[0024] See Figure 2Furthermore, the cross-sectional area of ​​the lifting link 3 at the end near the assist mechanism 2 is larger than the cross-sectional area at the end away from the assist mechanism 2. In this embodiment, the lifting link 3 is designed with one end face larger than the other, allowing it to have a certain degree of micro-deformation during lifting, thus buffering stress changes during walking and making the device's walking assistance smoother. Furthermore, in this embodiment, to reduce the weight of the lifting link 3 and thus the burden on the wearer, achieving a lightweight effect, the lifting link 3 is hollow inside. Furthermore, the lifting link 3 is made of carbon fiber material. Using carbon fiber further reduces the weight of the lifting link 3 while ensuring the reliability of its structural strength.

[0025] See Figure 2 A connecting block 6 is provided between the lifting link 3 and the connecting part 4. The circular end of the lifting link 3 is connected to the flat end of the connecting part 4 by the connecting block 6, so that the lifting force of the lifting link 3 can be effectively transmitted to the connecting part 4.

[0026] Furthermore, the waistband 1 is at least partially made of breathable mesh and configured as a breathable mesh structure to facilitate heat dissipation and ventilation.

[0027] In this embodiment, each of the two lifting links 3 is equipped with a switch button 31 and a torque adjustment button 32 for controlling the assist mechanism 2. By pressing and holding the switch button 31, the assist function of the assist component can be activated to assist walking. By pressing the torque adjustment button 32, the assist torque of the servo motor can be changed to achieve different assist effects. The torque adjustment button 32 is a stepped, cyclic adjustment. A fluorescent strip 33 is provided on one side of both the torque adjustment button 32 and the switch button 31 for illuminating the light when walking at night. It should be noted that the fluorescent strip 33 achieves its eye-catching function by reflecting light. In order to increase the reflective area, the fluorescent strip 33 is set to cover the entire outer end face of the lifting link 3. Of course, in some embodiments, the fluorescent strip 33 can also be set as a self-illuminating light strip structure. The energy part can be provided by the assist mechanism 2, or an independent power supply structure can be set and installed in the hollow part of the lifting link 3.

[0028] In summary, the walking aid device in the above embodiments of this utility model drives the lifting rod to rotate around the outer shell via a servo motor in the assistive component. This causes the other end of the lifting rod to simulate the human knee flexion movement, thereby driving the thigh fixation component fixed on the thigh to assist in lifting the thigh and reduce the lifting force of the thigh, thus achieving the function of assisting walking. Furthermore, the support plate and lifting rod are made of carbon fiber, which ensures the structural strength of the device while reducing the overall weight of the device, making the entire device lighter and more effortless to wear, and suitable for long-term walking.
