Abstract

This invention discloses a vibration-tactile training knee brace device for hearing-impaired dancers. Through the cooperation of an electromagnetic block, a magnetic block, and a traction belt, the movable part of the silicone ring on the knee brace is dynamically expanded. When the hearing-impaired dancer performs a compound movement of kneeling followed by an inward lateral slide, the electromagnetic block is activated, moving the traction belt and causing the movable part to expand outward. This allows the protective area of ​​the silicone ring to expand outward before the knee lateral slides inward, thus actively adhering to and continuously wrapping the inner edge of the knee. This effectively avoids the protection failure problem caused by relative sliding in traditional knee braces during such movements. Furthermore, the cooperation of a small suction cup, a silicone pad, and a thin flexible tube provides stable support for the silicone ring during a single kneeling movement, ensuring stable cushioning performance. When an inward lateral slide is required, the movement of the magnetic block can drive airflow to release the adhesion between the small suction cup and the silicone pad, achieving a switch between static locking and dynamic unlocking of the knee brace.

Description

Technical Field

[0001] This invention relates to the field of physical exercise, and in particular to a knee brace for training hearing-impaired dancers based on vibration tactile sensation. Background Technology

[0002] For hearing-impaired dancers, knee braces are far more than simple protective gear; they are core equipment for safeguarding their artistic careers and enhancing training effectiveness. On one hand, through cushioning and shock absorption, they effectively prevent acute injuries and chronic strain to the patella and meniscus during high-frequency, high-impact movements such as kneeling, gliding, and jumping, ensuring training safety and continuity. On the other hand, by installing vibration-sensing devices on the knee braces, they can provide real-time guidance on movement technique and transmit rhythmic information, thereby assisting hearing-impaired dancers in conducting better training.

[0003] The prior art CN201810691334.6 discloses a sports knee brace, in which a silicone ring is fixedly connected inside the hollowed-out groove, and an elastic spacer allows the user's skin to maintain a certain gap with the main body of the device without restraint. When the user squats and stands up, it will not cause a burden or tightness to the legs, thus improving the practicality of the main body of the device.

[0004] The prior art CN202222162559.7 discloses a knee pad for dance training. By setting up structures such as elastic bands, support strips and sponges, the elastic bands work together to make the circumferentially set extended pad fit the leg more fully. The elasticity of multiple elastic bands, together with the sponge in the protective pad, increases the cushioning effect while the leg moves, thus avoiding leg injury during training.

[0005] The knee brace structures in the aforementioned prior art all utilize cushioning pads or silicone rings for cushioning and protection during operation, mainly targeting the vertical impact of dancers, such as the impact protection from kneeling down. However, when dancers perform a kneeling and then inward sliding motion, the knee is prone to relative sliding between the knee and the cushioning pad, or the inner side of the knee may cross the inner area of ​​the silicone ring, causing the knee to easily slip out of the cushioning pad area when sliding outward, thus limiting the protection of the knee. Summary of the Invention

[0006] The core of this invention lies in the use of an electromagnetic block, a magnetic block, and a traction belt to dynamically expand the movable part of the silicone ring in the knee brace, thus solving the problem of protective failure caused by relative slippage during such movements in traditional knee braces. Simultaneously, the use of a small suction cup, a silicone pad, and a thin flexible tube allows for switching between static locking and dynamic unlocking, ensuring stable cushioning protection of the silicone ring during a single kneeling motion.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A vibration-tactile training knee brace for hearing-impaired dancers includes a knee brace layer for protecting the knee body. A vibration-tactile module is detachably installed on the surface of the knee brace layer near the inner side of the knee body. Two symmetrically arranged D-ring buckles are installed on one side of the knee brace layer, and two symmetrically arranged restraint straps are installed on the other side of the knee brace layer. The knee brace layer includes a surface layer, a buffer layer, and a skin-friendly layer arranged from the outside to the inside. The skin-friendly layer is close to the surface of the knee body. A silicone ring consisting of a fixed part and a movable part is installed through the inside of the buffer layer, and the movable part is close to the inner side of the knee body. Three guide boxes are installed near the edge inside the buffer layer. A magnetic block is slidably connected inside each guide box. A traction strap is connected to the surface of each magnetic block. The tail ends of the three traction straps are connected to the surface of the movable part. An electromagnetic block connected to the vibration-tactile module is installed on the inner wall of the guide box, and the electromagnetic block and the magnetic block repel each other.

[0009] Furthermore, a heat-insulating pad is installed on the side of the guide box near the skin-friendly layer, and the skin-friendly layer is made of breathable material, while a heat-conducting pad is installed on the side of the guide box near the surface layer.

[0010] Furthermore, the fixed part is bonded to the surface of the surface layer, while the movable part is slidably bonded to the surface of the surface layer.

[0011] Furthermore, after the knee pad is worn on the knee body, the three guide boxes are all located on the inside of the knee body. The buffer layer has three cavities inside to accommodate the three guide boxes, and the inner wall of the cavity opposite to the silicone ring is connected to a cushioning sponge.

[0012] Furthermore, a placement opening is provided on the side of the buffer layer near the surface layer corresponding to the cavity position. The traction belt consists of a retaining part and an outgoing part, wherein the outgoing part is fixed to the surface of the magnetic block and extends to the outside of the guide box, and the tail end of the retaining part is fixed to the surface of the moving part.

[0013] Furthermore, the end surfaces of the left-behind section and the outgoing section, which are close to each other, are respectively fitted with a felt side and a hook side of Velcro.

[0014] Preferably, three sets of small suction cups are arranged on the surface of the active part near the surface layer, with two small suction cups in each set. A silicone pad matching the three sets of small suction cups is embedded in the surface of the surface layer near the active part. A thin flexible tube is installed through the surface of the small suction cup, and the tail ends of the two thin flexible tubes in each set of small suction cups are respectively threaded to the inside of the three guide boxes.

[0015] Furthermore, the surface of the silicone pad near the moving part is flush with the surface of the surface layer near the moving part, and the thickness of the silicone pad is less than the thickness of the surface layer.

[0016] Compared with the prior art, the advantages of this invention are:

[0017] (1) This solution achieves dynamic expansion of the movable part of the silicone ring of the knee brace through the cooperation of electromagnetic blocks, magnetic blocks and traction belts. When the hearing-impaired dancer performs the compound action of kneeling down and then sliding inward, the electromagnetic blocks are activated to drive the traction belt to move, so that the movable part expands outward. This allows the protective area of ​​the silicone ring to expand outward in advance before the knee slides inward, thereby actively adhering to and continuously wrapping the inner edge of the knee. This effectively avoids the problem of protection failure caused by relative sliding in traditional knee braces during such actions, upgrading the knee brace from passive protection to active adaptive protection, improving safety during training and reducing foreign object interference.

[0018] (2) This solution solves the problem of possible slippage of the movable part under the vertical pressure applied by the patella when kneeling in one kneeling by using a combination of small suction cups, silicone pads and thin tubing. The suction cups provide stable support for the silicone ring when kneeling in one kneeling, ensuring stable cushioning performance. When it is necessary to perform the inward sliding action, the movement of the magnetic block can be used to drive the airflow to release the adhesion between the small suction cups and silicone pads, realizing the switching between static locking and dynamic unlocking.

[0032] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0033] Example 1:

[0034] Please see Figures 1-4 A vibration-tactile training knee brace for hearing-impaired dancers includes a knee brace layer 1 for protecting the knee body. A vibration-tactile module is detachably installed on the surface of the knee brace layer 1 near the inner side of the knee body. Two symmetrically arranged D-ring buckles are installed on one side of the knee brace layer 1, and two symmetrically arranged restraint straps 2 are installed on the other side of the knee brace layer 1. The knee brace layer 1 includes a surface layer 101, a cushioning layer 102, and a skin-friendly layer 103 arranged from the outside to the inside, wherein the skin-friendly layer 103 is close to the surface of the knee body, and the inner side of the cushioning layer 102... A silicone ring 3 consisting of a fixed part 31 and a movable part 32 is installed through the part, and the movable part 32 is close to the inner side of the knee body. Three guide boxes 5 are installed inside the buffer layer 102 near the edge. A magnetic block 51 is slidably connected inside each guide box 5. A traction strap 53 is connected to the surface of each magnetic block 51. The tail ends of the three traction straps 53 are connected to the surface of the movable part 32. An electromagnetic block 52 connected to the vibration tactile module is installed on the inner wall of the guide box 5, and the electromagnetic block 52 and the magnetic block 51 repel each other.

[0035] The fixed part 31 is bonded to the surface of the surface layer 101, and the movable part 32 is slidably connected to the surface of the surface layer 101.

[0036] Specifically, when using the knee brace of this application, the knee brace can be worn on the knee body of the hearing-impaired dancer (hereinafter referred to as the dancer) using the D-ring buckle and restraint strap 2. During the dancer's training, the vibration tactile module (which can be detached and installed by means of a snap fastener, or by other means, and is a vibration device built into the knee brace layer 1, and transmits different vibration movements through wireless signal transmission to provide a prompting effect, thereby assisting the hearing-impaired dancer in training; its working principle is existing technology and will not be elaborated here) is connected to the main control equipment in the training room via Bluetooth. It transmits the information of each movement beat to the knee body through vibration signals. Since most dance movements, such as squatting, kicking, jumping, turning, and sliding, rely heavily on the precise movement of the knee joint for power generation, control, and center of gravity transfer, placing the vibration tactile module on the knee brace layer 1 can directly transmit rhythm and movement instructions to the core muscle groups such as the quadriceps and hamstrings that control the movement of the knee joint.

[0037] When the dancer performs a kneeling motion, the kneecap is directly and vertically pressed against the buffer layer 102. At this time, the patella in the kneecap is directly fastened to the silicone ring 3 to achieve cushioning and shock absorption protection. The buffer layers 102 on the inner and outer sides of the silicone ring 3 cover and cushion the area around the patella. During this process, the three guide boxes 5 are all located in the outer area of ​​the patella (located near the edge of the knee pad layer 1). Therefore, the presence of the guide boxes 5 will not affect the protective effect of the knee pad layer 1 on the dancer's kneecap, and the dancer will experience less foreign body sensation when using it.

[0038] Please see Figures 5-6 When the dancer performs the movement of first kneeling and then sliding inwards, the angle between the inner edge of the patella and the ground gradually decreases. During this process, the inner edge of the patella will squeeze the area of ​​the silicone ring 3 near the inner side of the knee body, causing the inner edge to gradually move past the silicone ring 3 to the buffer layer 102 on the outer side of the silicone ring 3. Because the protective effect of the buffer layer 102 is less than that of the silicone ring 3 (in order to avoid the knee pad being too thick and affecting the flexibility of the knee body, the thickness of the knee pad layer 1 needs to be controlled, so the buffer layer 102 made of sponge material is thinner, but the shock absorption effect of the silicone ring 3 is significantly better than that of the buffer layer 102, so the buffer layer 102 provides less protection to the knee than the silicone ring 3 when performing the sliding inwards movement).

[0039] To improve the above-mentioned problems, and to ensure that the inner edge of the dancer is still surrounded by the movable part 32 for continuous cushioning protection when performing the inward lateral slide, a signal can be sent to the electromagnetic block 52 before the dancer is about to perform the inward lateral slide. This is because the vibration tactile module contains information about the dancer's entire dance sequence. During training, it not only transmits this information to the dancer via vibration signals but also connects with the electromagnetic block 52. During the dancer's training, just before the inward lateral slide, the electromagnetic block 52 is activated in advance, causing the movable part 32 to expand ahead of time. Subsequently, it sends a vibration signal corresponding to the inward lateral slide to the knee pad layer 1, allowing the dancer to perform the inward lateral slide normally and maintaining the smoothness of the training. This activates the electromagnetic block 52 and generates a repulsive force against the magnetic block 51, causing the magnetic block 51 to move away from the movable part 32. This, in turn, pulls the non-elastic material traction band 53 away from the movable part 32, causing the movable part 32 to expand outward by a small area (e.g., Figure 5 As shown in area a), the inner edge of the patella of the dancer's knee can still engage with the movable part 32 during the inward lateral slide, thus providing effective cushioning and shock absorption protection through the movable part 32.

[0040] As the inward sliding motion continues, the distance between the dancer's inner edge and the ground gradually decreases. This will exert a squeezing effect on the guide box 5. Because the guide box 5 is made of non-elastic material, the contact and squeezing between the inner edge and the guide box 5 will cause the guide box 5 to continue moving away from the moving part 32 along the cavity 104, thereby avoiding the feeling of a foreign object on the inner edge.

[0041] Please see Figure 3 A heat insulation pad 6 is installed on the side of the guide box 5 near the skin-friendly layer 103, and the skin-friendly layer 103 is made of breathable material. A heat-conducting pad 4 is installed on the side of the guide box 5 near the surface layer 101.

[0042] The use of heat insulation pad 6 can prevent the heat generated by electromagnetic block 52 when working from being transferred to the surface of the knee body, while the use of heat conduction pad 4 can allow the heat generated by electromagnetic block 52 when working to be transferred to the surface layer 101 to assist in heat dissipation. Both heat insulation pad 6 and heat conduction pad 4 are made of elastic materials, which can form a flexible covering treatment on the surface of guide box 5.

[0043] Please see Figure 4 After the knee pad 1 is worn on the knee body, the three guide boxes 5 are all located on the inner side of the knee body. The buffer layer 102 has three cavities 104 inside to accommodate the three guide boxes 5. The inner wall of the cavity 104 opposite to the silicone ring 3 is connected to the buffer sponge 7.

[0044] Specifically, after the inward sliding operation is completed, the electromagnetic block 52 is de-energized, and under the elastic action of the movable part 32, the magnetic block 51 is reset. If the inward sliding operation has a large amplitude and exerts a squeezing effect on the buffer sponge 7, the guide box 5 will also be reset under the elastic action of the buffer sponge 7.

[0045] Please see Figures 7-8 The buffer layer 102 has a placement opening 8 on the side surface near the surface layer 101 corresponding to the position of the cavity 104. The traction belt 53 consists of a guarding part 531 and an outgoing part 532, wherein the outgoing part 532 is fixed to the surface of the magnetic block 51 and extends to the outside of the guide box 5, and the tail end of the guarding part 531 is fixed to the surface of the movable part 32.

[0046] The end surfaces of the stationary section 531 and the outgoing section 532, which are close to each other, are respectively fitted with a felt side and a hook side of Velcro.

[0047] Specifically, when disassembling and cleaning the knee pad layer 1, after removing the vibration tactile module, the guide box 5 needs to be removed (because an electromagnetic block 52 is installed inside, it needs to be removed to avoid damage to the circuit during cleaning). At this time, the surface layer 101 is lifted accordingly, and then the placement opening 8 is opened (the design of the placement opening 8 is the same as the principle of an envelope-style pillowcase). The guide box 5 in the corresponding cavity 104 is removed, and the traction strap 53 is stretched so that the tail end of the retaining part 531 extends out of the placement opening 8. Then the outer part 532 is peeled off, and the guide box 5 can be removed. Then cleaning can be carried out.

[0048] Example 2:

[0049] Please see Figures 9-10 Three sets of small suction cups 9 are arranged on the surface of the movable part 32 near the surface layer 101. Each set of small suction cups 9 consists of two small suction cups. Silicone pads 11 that match the three sets of small suction cups 9 are embedded on the surface of the surface layer 101 near the movable part 32. Thin flexible tubes 10 are installed through the surface of the small suction cups 9, and the tail ends of the two thin flexible tubes 10 in each set of small suction cups 9 are respectively threaded to the inside of the three guide boxes 5.

[0050] The surface of the silicone pad 11 near the movable part 32 is flush with the surface of the surface layer 101 near the movable part 32, and the thickness of the silicone pad 11 is less than the thickness of the surface layer 101.

[0051] Specifically, in Embodiment 1, the movable part 32 is in sliding contact with the surface of the surface layer 101. Therefore, under vertical pressure (i.e., during a single kneeling action), the movable part 32 will slide under the pressure of the patella of the knee body, thereby weakening the overall buffering and protective effect of the silicone ring 3. To improve this phenomenon, a thin flexible tube 10, a small suction cup 9, and a silicone pad 11 are added based on Embodiment 1.

[0052] When vertical pressure is applied, the electromagnetic block 52 is in the off state. At this time, under the vertical pressure, the small suction cup 9 on the surface of the movable part 32 is pressed and achieves stable adsorption with the silicone pad 11, so that the surface layer 101 and the movable part 32 are in a constrained connection state, thereby providing stable support for the silicone ring 3, so that the silicone ring 3 can provide stable buffer protection for the patella.

[0053] When the inward sliding action is required laterally, as in Embodiment 1, the electromagnetic block 52 needs to be activated, the magnetic block 51 moves and generates a squeezing action, which can exert pressure on the left side of the magnetic block 51 inside the guide box 5 (within...). Figure 11 (For example) The space is compressed so that the internal gas can be discharged into the small suction cup 9 through the thin hose 10, so that the suction effect of the small suction cup 9 is released. Then the movable part 32 can move and expand under the action of the traction belt 53 as in Example 1.

[0054] The above description is merely a preferred embodiment of the present invention; it encompasses all the protection scope of the present invention. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solutions and improved concepts of the present invention, should be covered within the protection scope of the present invention.
