[0029] Please refer to Figures 1 to 5 As shown, this embodiment provides a bilateral OA knee brace massage rehabilitation device, including a knee brace body 1. A vibration motor 2 is detachably installed on the inner side of the knee brace body 1, and a controller 5 is fixedly installed on the outer side of the knee brace body 1. The end of the first wire 201 of the vibration motor 2 is electrically connected to a first terminal, and the first terminal is snapped into the output end of the controller 5.

[0030] Working principle: The controller 5 provides power and control signals to the vibration motor 2, which are transmitted through the first wire 201 to make the vibration motor 2 work, generate vibration, and massage the knee. The detachable design makes it easy to replace or repair the vibration motor 2.

[0031] In this embodiment, the knee pad body 1 has a threading hole 101 through which the first wire 201 of the vibration motor 2 passes.

[0032] The wire hole 101 provides a channel for the first wire 201, allowing the wire to pass through from the inside of the knee brace body 1 and connect to the controller 5 on the outside. At the same time, it ensures the integrity and sealing of the knee brace body 1, and avoids the wire being exposed, which may affect its use or cause safety hazards.

[0033] In this embodiment, four vibration motors 2 are provided, and the four vibration motors 2 are distributed in a rectangular shape on the inner side of the knee brace body 1.

[0034] The four vibration motors are arranged in a rectangular pattern to massage the area around the knee more evenly, covering a larger area and improving the massage effect. They act on the knee from multiple directions simultaneously to better relieve knee fatigue and pain.

[0035] Furthermore, at least two wire holes 101 are provided. At least two wire holes 101 can facilitate the passage of the first wire 201 of each vibration motor 2, avoiding the wires from getting tangled together, making installation and wiring easier, and also providing sufficient space for the wires to prevent them from being squeezed or damaged.

[0036] In this embodiment, an electric heating pad 3 is also included. The electric heating pad 3 is detachably installed on the inner side of the knee brace body 1. The end of the second wire 301 of the electric heating pad 3 is electrically connected to a second terminal, which is snapped into the output end of the controller 5.

[0037] The controller 5 provides power to the electric heating pad 3, which is transmitted through the second wire 301 to make the electric heating pad 3 heat up, providing heat to the knee, promoting blood circulation in the knee area, relieving muscle tension and pain. The detachable design makes it convenient to choose whether to use the electric heating function as needed, as well as to replace or repair the electric heating pad 3.

[0038] In this embodiment, the inner side of the knee pad body 1 is fixedly sewn with a first Velcro surface 102, and the back of the vibration motor 2 and the back of the electric heating pad 3 are both fixedly glued with a first Velcro hook surface.

[0039] By combining the first hook and loop fastener 102 and the first hook and loop fastener hook, the vibration motor 2 and the electric heating pad 3 are detachably connected to the knee pad body 1, which facilitates installation and disassembly. At the same time, the hook and loop fastener connection method can ensure the connection is firm and prevent the vibration motor 2 and the electric heating pad 3 from shifting during use.

[0040] In this embodiment, a skin-friendly layer 4 is fixedly connected to the inner side of the knee brace body 1. The vibration motor 2 and the electric heating pad 3 are both located between the skin-friendly layer 4 and the knee brace body 1. A slit 401 is provided on the skin-friendly layer 4.

[0041] The skin-friendly layer 4 can improve the user's comfort and reduce the direct stimulation of the skin by the knee brace body 1, vibration motor 2 and electric heating pad 3. The slit 401 can make the skin-friendly layer 4 better adapt to the bending and movement of the knee and avoid restricting the movement of the knee. At the same time, when the vibration motor 2 and electric heating pad 3 malfunction, the user can remove the damaged vibration motor 2 or skin-friendly layer 4 through the slit 401.

[0042] In this embodiment, the skin-friendly layer 4 is a polyurethane breathable layer.

[0043] The polyurethane breathable layer has excellent breathability, allowing the skin to breathe and preventing stuffiness and dampness caused by sweating during use, thus improving comfort and hygiene. At the same time, the polyurethane material also has a certain degree of elasticity and softness, further enhancing its skin-friendly effect.

[0044] In this embodiment, a shielding layer 6 for shielding the first wire 201 and the second wire 301 is provided on the outer side of the knee brace body 1. One side of the shielding layer 6 is fixedly sewn to the outer side of the knee brace body 1, and a third hook and loop fastener 601 is fixedly sewn to the other side of the shielding layer 6. A third hook and loop fastener 107 is fixedly sewn to the outer side of the knee brace body 1.

[0045] The shielding layer 6 is used to shield the first wire 201 and the second wire 301, making the knee brace look neater and more beautiful. At the same time, it can also protect the wires from external friction, pulling and damage. The third hook and loop side 601 and the third hook and loop side 107 cooperate to facilitate the opening and closing of the shielding layer 6, making it easy to inspect or repair the wires.

[0046] In this embodiment, the upper and lower ends of both sides of the knee pad body 1 are respectively sewn with a first connecting strap 103 and a first connecting ear 104. The end of the first connecting strap 103 is fixedly sewn with a second hook and loop fastener 105, and the end of the first connecting ear 104 is fixedly sewn with a second hook and loop fastener 106.

[0047] By cooperating with the second Velcro hook side 105 and the second Velcro loop side 106 on the first connecting strap 103 and the first connecting ear 104, the knee brace body 1 can be fixed on the knee and can be adjusted according to the user's leg circumference to ensure the fit and stability of the knee brace, so that the knee brace will not easily slip off or shift during use.

[0048] Considering that this bilateral OA knee massage rehabilitation device needs to simultaneously control the vibration motor 2 and the electric heating pad 3, and requires stable power transmission and signal control functions, the Arduino Nano can be selected as the controller 5. The Arduino Nano is compact and easy to install on the outside of the knee brace body 1. It also has a wealth of input / output interfaces, which can meet the control needs of multiple vibration motors 2 and electric heating pads 3. In addition, its programming is flexible, and parameters such as the vibration frequency of the vibration motor 2 and the heating temperature of the electric heating pad 3 can be adjusted according to actual usage requirements.
