[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] In the existing technology, knee braces used for knee joint rehabilitation are relatively bulky and inconvenient for patients to wear and use in their daily lives during the later stages of knee joint rehabilitation. At the same time, the inner lining material that fits tightly against the leg cannot be removed and cleaned, which makes it easy for bacteria to grow on the knee brace after a period of use, which is not good for the patient's health. Furthermore, when the support structure on one side is damaged, the entire brace needs to be replaced, increasing the cost of use.

[0015] In view of this, the present invention provides a knee brace with a limiting support structure. Through the cooperation of a knitted sleeve, elastic band, first support strip, second support strip, adjusting hinge, telescopic strip, connecting plate, fixing buckle, first fixing hole, second fixing hole, fixing strap, Velcro, and notch, the knee joint limiting support structure is fixed to both sides of the knitted sleeve by Velcro and buckle structure. The patient slips the knitted sleeve onto the knee and uses the fixing strap to secure it at the thigh and calf, allowing the limiting support structure to form a stable support on both sides of the knee. The design incorporates support and restraint to improve the ease and comfort of wearing knee braces, reducing their bulkiness. Furthermore, the knitted sleeve and knee joint restraint support structure are detachable, allowing patients to easily disassemble, clean, or replace the knitted sleeve, preventing bacterial growth after prolonged use. Additionally, if the knee joint restraint support structure on one side is damaged, the damaged side can be replaced separately, improving the ease of maintenance and cost-effectiveness of use. This makes it convenient for patients to wear and use in their daily lives during the later stages of knee rehabilitation.

Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0017] Depend on Figure 1-5 It is known that the knee brace with a limiting support structure includes a knitted sleeve 1. Elastic bands 2 are provided at both ends of the knitted sleeve 1. First support bars 3 are provided on the upper sides of both sides of the knitted sleeve 1, and second support bars 4 are provided on the lower sides of both sides of the knitted sleeve 1. The second support bars 4 are rotatably connected to the first support bars 3 via adjusting hinges 5. Telescopic bars 6 are movably connected to the ends of the first and second support bars 3 and 4 away from the adjusting hinges 5. A connecting plate 7 is provided at the end of the telescopic bars 6 away from the adjusting hinges 5. Fixing buckles 8 are fixedly connected to the upper and lower sides of both sides of the knitted sleeve 1. A first fixing hole 9 is provided on the outer wall of the connecting plate 7. The fixing buckle 8 is connected to the first fixing hole 9. The fixed hole 9 is connected to the connecting plate 7, which has a second fixed hole 10 on both sides of the first fixed hole 9. The front and rear ends of the knitted sleeve 1 are provided with fixing straps 11. One end of the fixing strap 11 is fixedly connected to the second fixed hole 10, and the fixing strap 11 is connected to the second fixed hole 10 on the other side. The outer wall of the fixing strap 11 is provided with Velcro 12. The middle rear side of the knitted sleeve 1 is provided with a notch 13. The notch 13 is located on the back of the knitted sleeve 1 at the patient's popliteal fossa and is edge-locked to reduce the pressure of the knitted sleeve 1 bending and wrinkles on the popliteal fossa when the patient wears the knee brace, thereby improving the wearing comfort.In the specific implementation process, it is worth noting that, through the cooperation between the knitted sleeve 1 and the elastic band 2, and by using a sleeve-structured knitted material, the knee brace can fit snugly against the patient's leg, improving the convenience and comfort of wearing it. Furthermore, the knitted sleeve 1 effectively wicks away sweat, reducing discomfort during prolonged wear in daily life. Simultaneously, the elastic band 2 provides sufficient elasticity at both ends of the knitted sleeve 1, allowing it to tightly wrap around the patient's leg, preventing the knee brace from slipping off during use and improving its stability. Through the cooperation between the knitted sleeve 1, the elastic band 2, the first support bar 3, the second support bar 4, and the adjusting hinge 5, the first and second support bars 3 and 4 are secured with Velcro and pins on the side closest to the knitted sleeve 1. The knitted sleeve 1 is connected to facilitate the disassembly and separation of the first support bar 3, the second support bar 4, and the knitted sleeve 1. The first support bar 3 and the second support bar 4 are made of lightweight, high-strength materials, such as aluminum alloy or carbon fiber, and are connected by an adjusting hinge 5. By adjusting the positions of the flexion and extension adjustment knobs on the adjusting hinge 5, the rotation angle between the first support bar 3 and the second support bar 4 can be limited, so that the flexion and extension of the knee joint can be independently limited. This allows the knee brace to better adapt to the different degrees of knee flexion of different patients according to their recovery. The adjusting hinge 5 is also equipped with a locking button. After adjustment, the locking button can be pressed to lock the adjusting hinge 5 and prevent it from loosening during use. This design enhances the stability and safety of the knee brace, effectively reducing its overall weight while maintaining support strength, making it convenient for patients to wear in daily life. Through the cooperation of the knitted sleeve 1, elastic band 2, first support strip 3, second support strip 4, adjusting hinge 5, telescopic strip 6, connecting plate 7, fixing buckle 8, and first fixing hole 9, the telescopic strip 6 is inserted into the ends of the first and second support strips 3 and 4 away from the adjusting hinge 5, allowing for adjustment and fixation of the telescopic length. Fixing buckles 8 are fixed to both sides of the knitted sleeve 1. By passing the fixing buckles 8 through the first fixing hole 9 and adjusting the telescopic length of the telescopic strip 6, the fixing buckles 8 are limited within the first fixing hole 9, thus achieving fixation between the two ends of the knitted sleeve 1 and the support structure. The knitted sleeve 1 can be disassembled and separated from the support structure by removing the fixing buckle 8 from the first fixing hole 9, so that the knitted sleeve 1 can be disassembled, cleaned, or replaced. Through the cooperation between the knitted sleeve 1, elastic band 2, first support strip 3, second support strip 4, adjusting hinge 5, telescopic strip 6, connecting plate 7, second fixing hole 10, fixing strap 11, and Velcro 12, one end of the fixing strap 11 is fixed to the second fixing hole 10 of the connecting plate 7, and the fixing strap 11 is inserted into the corresponding second fixing hole 10 of the connecting plate 7 on the other side, and then fixed by the Velcro 12 after being pulled back. A stable ring structure is formed at both ends of the limiting support structure on both sides of the knitted sleeve 1, forming a stable binding force at both the upper and lower parts of the patient's knee joint.It can adapt to different patients' leg circumferences, improving the stability and support effect of the knee brace during wear. Notch 13 is located on the back of the knitted sleeve 1 at the patient's popliteal fossa and is edge-locked to reduce pressure on the popliteal fossa caused by the bending and folding of the knitted sleeve 1, improving wearing comfort. Through the cooperation of the knitted sleeve 1, elastic band 2, first support strip 3, second support strip 4, adjusting hinge 5, telescopic strip 6, connecting plate 7, fixing buckle 8, first fixing hole 9, second fixing hole 10, fixing strap 11, Velcro 12, and notch 13, the knee joint limiting support structure is fixed on both sides of the knitted sleeve 1 via Velcro and buckle structures. The patient can then use the knitted sleeve 1 to support the knee brace. The sleeve 1 is slipped onto the knee and secured at the patient's thigh and calf with the fixing strap 11. This ensures that the limiting support structure provides stable support and limitation on both sides of the knee, improving the ease and comfort of wearing the knee brace and reducing its bulkiness. Furthermore, the knitted sleeve 1 and the knee joint limiting support structure are detachable, allowing patients to easily disassemble, clean, or replace the knitted sleeve 1, preventing bacterial growth after prolonged use. Additionally, if the knee joint limiting support structure on one side is damaged, the damaged side can be replaced separately, improving the ease of maintenance and cost-effectiveness of the knee brace. This makes it convenient for patients to wear in their daily lives during the later stages of knee rehabilitation. Furthermore, the outer wall of the telescopic strip 6 is provided with a vertical groove 14, and an adjustment hole 15 is provided at equal intervals on one side of the vertical groove 14. The inner wall of the first support strip 3 and the second support strip 4 away from the adjustment hinge 5 is provided with an installation groove 16. A square tube 17 is connected to the inner wall of the installation groove 16. The inner wall of the square tube 17 is connected to the telescopic strip 6. An adjustment button 18 is provided on one side of the outer wall of the square tube 17. The adjustment button 18 passes through the first support strip 3 and the second support strip 4 respectively. A limit block 19 is provided inside the square tube 17. The limit block 19 is connected to the vertical groove 14. Limit teeth 20 are provided at equal intervals on one side of the outer wall of the limit block 19. The limit teeth 20 are connected to the adjustment hole 15. A compression spring 21 is fixedly connected at equal intervals on the inner wall of the installation groove 16 away from the adjustment button 18. The compression spring 21 abuts against the square tube 17. In the specific implementation process, it is worth noting that, through the cooperation between the first support bar 3, the second support bar 4, the telescopic bar 6, the mounting groove 16, the square tube 17, the adjusting button 18, and the compression spring 21, the compression spring 21 provides elastic force to the square tube 17 towards the adjusting button 18, ensuring that the square tube 17 is always on the side away from the compression spring 21 inside the mounting groove 16. By pressing the adjusting button 18, the square tube 17 moves towards the compression spring 21 inside the mounting groove 16, compressing the compression spring 21. Simultaneously, after stopping the pressing of the adjusting button 18, the square tube 17 resets under the action of the compression spring 21. Through the cooperation between the first support bar 3, the second support bar 4, the telescopic bar 6, the vertical groove 14, the adjusting hole 15, the mounting groove 16, the square tube 17, the adjusting button 18, the limiting block 19, the limiting teeth 20, and the compression spring 21, pressing the adjusting button 18... The square tube 17 is moved closer to the compression spring 21. At the same time, the limiting tooth 20 moves out of the adjustment hole 15, releasing the limitation on the telescopic strip 6 and realizing the telescopic adjustment of the telescopic strip 6. After the adjustment button 18 is stopped, the square tube 17 is reset under the action of the compression spring 21, and the limiting tooth 20 is re-engaged in the adjustment hole 15 to lock the telescopic strip 6. Through the cooperation between the first support bar 3, the second support bar 4, the telescopic strip 6, the vertical groove 14, the adjustment hole 15, the mounting groove 16, the square tube 17, the adjustment button 18, the limiting block 19, the limiting tooth 20 and the compression spring 21, the telescopic strip 6 located at the end of the first support bar 3 and the second support bar 4 can be telescopically adjusted, thereby realizing the length adjustment of the support structure located on both sides of the knee joint, adapting to different leg lengths, meeting the usage needs of different leg types and different age groups, and improving the applicability and comfort of the knee brace. Furthermore, the outer wall of the adjustment button 18 is provided with a groove 22, and the adjustment button 18 is provided with anti-slip textures 23 at equal intervals inside the groove 22; In the specific implementation process, it is worth noting that by adjusting the cooperation between the adjustment button 18, the groove 22 and the anti-slip texture 23, the friction of the adjustment button 18 is improved, the stability and comfort of the user when pressing the adjustment button 18 are increased, and the accuracy and convenience of adjusting the telescopic strip 6 are improved. Furthermore, an annular silicone protective pad 24 is embedded in the side of the knitted sleeve 1 away from the notch 13; In the specific implementation process, it is worth noting that after the knee brace is worn, the ring-shaped silicone protective pad 24 wraps around the lower edge and sides of the patella, restricting abnormal sliding or lateral displacement of the patella during flexion and extension activities, reducing misalignment and friction between the patella and the femoral trochlea. At the same time, when the knee is impacted, the ring-shaped silicone protective pad 24 can also play a buffering role, effectively reducing the impact force on the knee joint and further improving the protective performance of the knee brace. Furthermore, the top of the connecting plate 7 located above is provided with an anti-slip hook 25, which is used to connect the neck strap and provide traction at the top of the knee pad to prevent the knee pad from sliding down and shifting during wearing. In the specific implementation process, it is worth noting that the anti-slip hook 25 is used to connect the neck strap and provide traction at the top of the knee pad to prevent the knee pad from sliding down and shifting during the wearing process.
