[0021] Existing lower limb exercise assisting devices generally use spring structures or electric systems for assisting. However, if the electric assisting device repeatedly replaces the battery or charges frequently, it will lead to high costs and environmental pollution, and will inevitably limit the advantages of wearable devices in terms of portability and convenience. Therefore, in the assisting process of lower limb exercise assisting devices, knee joint assisting devices mostly use springs to provide assisting power, and the assisting effect is not very obvious.

[0022] In view of the above problems, the utility model installs a first spring assembly and a second spring assembly to support the thigh guard and the calf guard to recover after the thigh guard and the calf move relative to each other, thereby forming a power source. When the thigh guard and the calf move relative to each other, electric energy is generated by the Farasis energy assembly, and the generated electric energy is stored in a battery through a rectifier circuit board. External power supply is provided, and the power generation source is easy to obtain and environmentally friendly, and can also power electrical equipment on the device.

[0023] The technical solution of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0024] See also Figure 1-3 The utility model provides a knee joint assist and energy capture device, including a thigh guard 1, a calf guard 2, and a Funeng component 5;

[0025] In this embodiment, the thigh guard 1 and the calf guard 2 are connected through the Farasis component 5, and the Farasis component 5 is used to generate electrical energy after the thigh guard 1 and the calf guard 2 move relative to each other. Specifically, the Farasis component 5 includes a rotating shaft 8, one end of which is mounted on the calf guard 2, and the other end of the rotating shaft 8 is rotatably supported on the thigh guard 1 through a bearing 13. A bracket 9 is mounted on the thigh guard 1, and the inner side of the bracket 9 is annular and evenly distributed with piezoelectric sheets 12. A gear 10 is also mounted on the rotating shaft 8, and each tooth tip on the gear 10 is equipped with a contact head 11 for contacting the piezoelectric sheet 12. During the patient's walking process, the thigh guard 1 and the calf guard 2 rotate relative to each other, and the rotating shaft 8 drives the gear 10 to rotate. Since the bracket 9 is fixedly installed, the contact head 11 on the gear 10 can hit the piezoelectric sheet 12 during clockwise or counterclockwise rotation, and the piezoelectric sheet 12 generates electricity after deformation. A rectifier circuit board 6 and a battery 7 are also installed on the calf guard 2, which are used to collect the electric energy generated by the Farasis energy component 5. After the piezoelectric sheet 12 is deformed and generates electricity, the electric energy generated by the deformation of the piezoelectric sheet 12 enters the rectifier circuit board 6 through a wire for rectification and voltage stabilization and then stored in the battery 7. The battery 7 is a rechargeable battery 7.

[0026] In this embodiment, the first spring assembly 3 is installed on the inner side of the thigh guard 1 and the calf guard 2, and the second spring assembly 4 is installed on the outer side of the thigh guard 1 and the calf guard 2. The thigh guard 1 and the calf guard 2 move relative to each other, and the elastic potential energy is obtained through the first spring assembly 3 and the second spring assembly 4 to form an assisting force; the first spring assembly 3 generates a restoring force for the thigh guard 1 and the calf guard 2 in the process of bending along the rear side, respectively, to form a supporting and assisting effect, and the second spring assembly 4 generates a restoring force for the thigh guard 1 and the calf guard 2 in the process of bending along the front side, respectively, to form a supporting and assisting effect, thereby forming two assisting sources when the thigh guard 1 and the calf guard 2 move relative to each other.

[0027] On the basis of the above, an electric power assist device can also be provided. Specifically, the electric power assist device includes a power assist motor 14 installed on the thigh guard 1. The output end of the power assist motor 14 is connected to the rotating shaft 8, and the rotating shaft 8 is connected to an angle sensor 16 through a gear transmission mechanism 15. A controller 17 is also installed on the calf guard 2. The controller 17 uses a PLC, so that when the patient uses the utility model, in a mode without electric power assist, the rotation angles of the thigh guard 1 and the calf guard 2 during use are detected, and stored through the angle sensor 16 and the controller 17, so that the power assist motor 14 is reversed to form electric power assist. The generated electric energy is stored in the battery 7 to power the power assist motor 14, which well meets the needs of patients and can be charged without or with less charge, thereby achieving the purpose of energy saving and environmental protection.

[0028] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
