Description

Technical Field

[0001] This utility model mainly relates to the field of human movement assistance technology, specifically a knee joint movement assistance support bracket. Background Technology

[0002] A knee support brace is a wearable sports protection device that spans the thigh and calf through a mechanical structure, acting on the knee joint. Its core function is to provide external support during movement, distributing the physiological load on the knee joint, limiting abnormal range of motion, and preventing injury, reducing fatigue, and aiding rehabilitation by cushioning impact and assisting in force application.

[0003] Most existing knee support devices use rigid support, which can provide static stability but cannot effectively cushion the instantaneous impact on the knee joint when the foot lands. Secondly, the assist transmission mechanism of traditional devices is often out of sync with the natural flexion and extension movements of the human knee joint, resulting in movement delays or mismatches in force lines. This not only affects the effectiveness of the assist, but the resulting jerking and incoordination can also interfere with the user's normal gait, disrupt the continuity of movement, and may lead to compensatory sports injuries with long-term use. Utility Model Content

[0004] This utility model mainly provides a knee joint movement assist support bracket to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A knee joint motion assist support bracket includes a first bracket and a second bracket. A force adjuster is fixedly installed on the top of the first bracket, and a first support component is provided at the bottom of the first bracket. The second bracket has a second support assembly at the top and a pedal assembly at the bottom of one side.

[0006] Preferably, the first support assembly includes a spring, a first connecting block, and a protective sleeve. The spring is fixedly installed at the bottom of the first bracket, and the first connecting block is fixedly installed at the bottom of the spring. A protective sleeve is provided on the outside of the spring.

[0007] Preferably, the second support component includes a support block, a placement groove, and a steel wire rope. The top of the bracket is provided with multiple support blocks, and the multiple support blocks are connected to each other by a rotating shaft. The top of the uppermost support block is fixedly connected to the bottom of the first connecting block. Placement grooves are provided on both sides of one end of the surface of the support block, and steel wire ropes are installed inside the two placement grooves. The tops of the two steel wire ropes are fixedly connected to the bottom of the first connecting block, and the bottoms are fixedly connected to the top of the second bracket.

[0008] Preferably, the pedal assembly includes a mounting block, a second connecting block, and a foot pedal. The mounting block is fixedly mounted on one bottom side of the second bracket, and the second connecting block is connected to one bottom side of the mounting block via a pivot. The foot pedal is also connected to one bottom side of the second connecting block via a pivot.

[0009] Preferably, the protective sleeve is a retractable corrugated tube structure, and the top end of the protective sleeve is interference-fitted with the bottom of the first bracket, and the bottom end is interlocked with the top of the first connecting block or snap-fitted.

[0010] Preferably, the bottom of the foot pedal has textured patterns for anti-slip purposes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Throughout the exercise, the spring not only acts as an energy storage element but also plays a crucial role in cushioning. When the foot lands and experiences impact, the compression of the spring effectively absorbs and disperses the instantaneous impact force acting on the knee joint. During the exertion phase, its elastic release process is smooth and continuous, avoiding the movement abruptness and joint stress concentration that may result from rigid support. At the same time, multiple support blocks, in conjunction with steel cables, ensure that the power transfer is highly synchronized with the natural flexion and extension of the knee joint, providing stable and smooth support and protection for the knee joint and effectively reducing the risk of sports injuries.

[0015] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0016] Please refer to the appendix carefully. Figure 1-4A knee joint motion assist support bracket includes a first bracket 1 and a second bracket 2. The first bracket 1 is fixed to the user's thigh via Velcro, and the second bracket 2 is fixed to the user's lower leg via Velcro, together forming a cross-joint support base for the knee joint. A force adjuster 3 is fixedly installed on the top of the first bracket 1. The force adjuster 3 adjusts the preload applied to the elastic element in real time according to the user's weight and physical condition. A first support component 4 is provided at the bottom of the first bracket 1. The first support component 4 includes a spring 401, a first connecting block 402, and a protective sleeve 403. The upper end of the spring 401 is welded to the bottom of the first bracket 1 to achieve rigidity. The lower end is fixed and firmly connected to the first connecting block 402 in the same way, making the spring 401 the core medium for transmitting and converting force. The protective sleeve 403 adopts a retractable corrugated tube structure. The top of the protective sleeve 403 is wrapped around the bottom outside of the first bracket 1 by interference fit, and the bottom of the protective sleeve 403 is connected to the top of the first connecting block 402 in the same way, effectively preventing common foreign objects such as mud, sand, water and dust from entering the spring 401, preventing the spring 401 from failing or malfunctioning due to impurities. The top of the second bracket 2 is provided with a second support component 5. The second support component 5 includes a support block 501, a placement groove 502, and a steel wire rope 503. The components are connected in series via a pivot, forming a flexible bending structure in the sagittal plane. The top of the uppermost support block 501 is fixedly connected to the bottom of the first connecting block 402. Each support block 501 has symmetrical placement slots 502 on both sides of one end. Steel wire ropes 503 are placed in the placement slots 502 on both sides, with their tops passing through the first connecting block 402 and fixed by a pressure plate, and their bottoms connected to the top of the second bracket 2. This ensures uniform force distribution and avoids structural distortion caused by unilateral force. When the knee joint bends, the angle between the support blocks 501 changes, transmitting the movement of the lower leg to the spring 401, while simultaneously releasing the spring 401. The force is transmitted in the opposite direction to the lower leg, achieving efficient force transmission and ensuring a high degree of synchronization between the assisted movement and the natural movement of the human body. A pedal assembly 6 is provided on the bottom side of the second support 2. The pedal assembly 6 includes a mounting block 601, a second connecting block 602, and a foot pedal 603. The mounting block 601 is fixed at a suitable height on the side wall of the second support 2. Its bottom is connected to the upper end of the second connecting block 602 through a pivot. The lower end of the second connecting block 602 is connected to the rear of the foot pedal 603 through a pivot, so that the foot pedal 603 can adapt to the user's foot movement angle. The bottom of the foot pedal 603 is provided with anti-slip texture 7 to increase the static friction between the sole of the foot and the pedal and prevent the foot from slipping when pedaling.

[0017] The specific operation method of this utility model is as follows: In use, the user secures the first support 1 to the thigh and the second support 2 to the calf using Velcro. The user can pre-operate the force adjuster 3 according to their own weight. The adjuster changes the initial compression of the spring 401 by pushing it downward, thereby setting the support force. When the knee is bent, the user steps on the foot pedal 603, whose bottom anti-slip texture 7 effectively prevents slipping. The force is transmitted to the second support 2 through the second connecting block 602 and the mounting block 601, causing it to tend to move upward. This upward force is then converted into an upward force through the steel wire rope 503. The tension of the steel wire rope 503 causes it to slide within the placement groove 502 of the support block 501, pulling the first connecting block 402. This causes the pre-compressed spring 401 to be further compressed and store more energy. When the leg is straightened, the double-compressed spring 401 releases energy, exerting a downward pushing force on the support block 501 through the first connecting block 402 and an upward lifting force on the second support 2 through the steel wire rope 503. These two forces work together to assist in straightening the knee joint, thereby significantly reducing the burden on the leg muscles and achieving a labor-saving effect.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
