Description

Technical Field

[0001] The invention relates to the technical field of sports protective equipment, in particular to an adjustable anti-sprain sports knee pad. Background Art

[0002] The knee is an extremely important part in sports, but it is also a relatively fragile part that is easily injured. In some sports activities, the excessive pressure on the knees, coupled with strenuous exercise, can easily cause diseases of the knee joint. Wearing knee pads can ensure that the knee is not easily injured.

[0003] Most existing knee pads are made of elastic fabrics and cannot specifically protect against knee sprains. Ordinary protective gear is easy to shift during exercise, and the fixation effect decreases after long-term use, affecting the protective effect. There is a lack of dynamic pressure regulation. If worn too tightly for a long time, it may affect blood circulation. In addition, during multi-person sports, the knee joint is not only facing the risk of twisting, but is also often subjected to external impact forces due to collisions or accidental contact, which may cause soft tissue contusion, bone contusion or even fracture. Existing knee pads only rely on elastic materials to absorb impact force, resulting in poor anti-collision effect. Therefore, in order to solve the above defects, the inventors propose an adjustable anti-sprain sports knee pad. Summary of the Invention

[0004] The main purpose of the present invention is to provide an adjustable anti-sprain sports knee pad, which can effectively solve the problem that the sports knee pad in the prior art only relies on elastic materials to absorb impact force, resulting in poor anti-collision effect.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] An adjustable anti-sprain sports kneepad includes a kneepad body and straps mounted on the upper and lower sides of the kneepad body. A first anti-collision pad is provided on the front surface of the outer surface of the kneepad body and on both the left and right sides of the outer surface of the kneepad body, and a second anti-collision pad is provided on the rear surface of the outer surface of the kneepad body. The first anti-collision pad includes a first memory foam layer, and an EVA bottom layer is fixedly mounted on the bottom of the first memory foam layer.

[0007] The second anti-collision pad includes a second memory foam layer, and a TPU skeleton layer is provided inside the second memory foam layer. Connecting belts are fixedly installed on both sides of the first anti-collision pad and the second anti-collision pad, and a fixing strip is fixedly installed on one side of the connecting belt. Two connecting blocks are provided on the front and rear sides of the outer surface of the knee pad body and on the left and right sides of the knee pad body.

[0008] Preferably, a fixing hole is provided on one side of the interior of the connecting block, and silicone pads are fixedly installed on both sides of the inner wall of the fixing hole. A driving cavity is provided on one side of the connecting block, and a limiting rod is slidably connected to the interior of the driving cavity. One end of the limiting rod extends to the interior of the fixing hole. Two springs are fixedly installed on one side of the interior of the driving cavity, and the limiting rod is fixedly connected to the two springs on one side of the interior of the driving cavity.

[0009] Preferably, a movable cavity is provided inside the connecting block, and a connecting rod is slidably connected inside the movable cavity, and one side of the connecting rod extends into the interior of the driving cavity and is fixedly connected to the limiting rod.

[0010] Preferably, a guide hole is provided on the inner top surface of the movable cavity, a shift block is fixedly installed on one side of the connecting rod located inside the movable cavity, and the shift block extends through the guide hole to the outside of the connecting block.

[0011] Preferably, a limiting hole is provided on one side of the fixing strip.

[0012] Preferably, an annular support area is provided on one side of the patella on the outer surface of the kneepad body, protective strips are provided on both sides of the knee joint on the outer surface of the kneepad body, and two angle sensors are provided on one side of the outer surface of the kneepad body.

[0013] Preferably, the knee pad body includes a skin-friendly layer, an elastic support belt is fixedly installed on the outer surface of the skin-friendly layer, and a wear-resistant and breathable mesh is fixedly installed on the outer surface of the elastic support belt.

[0014] Preferably, the protective strip comprises a skin-friendly breathable layer, an elastic buffer layer is fixedly mounted on the outer surface of the skin-friendly breathable layer, and a memory alloy wire mesh is provided inside the elastic buffer layer.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention discloses an adjustable anti-sprain sports kneepad, which is provided with a first anti-collision pad and a second anti-collision pad. In actual work:

[0017] 1. The data from the two angle sensors are synchronously transmitted to the built-in control chip, driving the memory alloy mesh to expand and contract. When the wearer exercises, the mesh contracts and tightens to enhance the wrapping. When the wearer is stationary, the mesh relaxes to reduce pressure. The 45° oblique weaving pattern forms cross damping through the fiber direction and the potential torque direction. When the knee joint is subjected to horizontal lateral force, the obliquely woven fibers can generate a reverse component of force to offset part of the torque.

[0018] 2. Pull the shift block to move the limit rod toward the inside of the drive cavity and squeeze the spring, insert the fixing bar into the fixing hole, and the silicone pad will deform to increase friction. Release the shift block, and the squeezed spring will push the limit rod into the limit hole to complete the installation of the first anti-collision pad and the second anti-collision pad. When the knee joint is subjected to a momentary impact, the anti-collision module disperses the impact force through the "layered buffering" mechanism. The memory foam absorbs the impact energy through material deformation, prolongs the action time, and reduces the peak pressure. The EVA bottom layer uses the elastic deformation of the material to further absorb energy, and at the same time evenly diffuses the remaining impact force to the surrounding soft tissue to avoid local concentrated force, thereby effectively improving the anti-collision effect and effectively avoiding knee joint injuries caused by external collisions.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] The present invention discloses an adjustable anti-sprain sports knee pad, such as Figure 1-9 As shown, it includes a kneepad body 1 and straps 2 installed on the upper and lower sides of the kneepad body 1. The two straps 2 are respectively located at the thigh and calf of the kneepad body 1.

[0031] The knee pad body 1 includes a skin-friendly layer 1033, and an elastic support belt 1032 is fixedly installed on the outer surface of the skin-friendly layer 1033, and a wear-resistant and breathable mesh 1031 is fixedly installed on the outer surface of the elastic support belt 1032, which mainly undertakes external friction protection and basic ventilation without complex density changes. The wear-resistant and breathable mesh 1031 is made of polyester fiber. The wear-resistant and breathable mesh 1031 adopts a three-dimensional warp knitting structure, and the warp and weft yarns are tightly interwoven to avoid mesh deformation due to stretching during exercise.

[0032] The elastic support belt 1032 is made of aramid fiber and adopts an oblique cross-weaving process. The oblique fibers form a 45° angle with the direction of movement of the knee joint, dispersing external forces in the horizontal and front-to-back directions. The cross-weaving points form "mechanical nodes" to enhance local shear resistance.

[0033] The material of the skin-friendly layer 1033 is Modal, and the comfort of the skin-friendly layer 1033 is further improved by adding a hydrophilic agent.

[0034] Since different parts of the knee joint are subjected to significant differences in force during exercise, gradient density weaving technology is used to target high-stress areas, such as the sides of the patella and the areas covered by the medial and lateral collateral ligaments, with high-density weaving to enhance local wrapping strength, while the density is reduced in low-stress areas to avoid excessive restraint that affects blood circulation.

[0035] In addition, a high-density annular support area 1021 is designed around the patella, and gradient density technology is used to enhance local wrapping, limit abnormal displacement of the patella, and reduce the risk of dislocation.

[0036] A first anti-collision pad 4 is provided on the front side of the outer surface of the kneepad body 1 and on the left and right sides of the outer surface of the kneepad body 1, and a second anti-collision pad 5 is provided on the rear side of the outer surface of the kneepad body 1. The three first anti-collision pads 4 can protect the front side and left and right sides of the knee joint. The first anti-collision pad 4 includes a first memory foam layer 401, and an EVA bottom layer 402 is fixedly installed on the bottom of the first memory foam layer 401. When the knee joint is subjected to an instantaneous impact, the anti-collision pad disperses the impact force through a "layered buffering" mechanism. The memory foam layer absorbs impact energy through material deformation, prolongs the action time, and reduces the peak pressure. The EVA bottom layer 402 utilizes the elastic deformation of the material to further absorb energy, and at the same time evenly diffuses the remaining impact force to the surrounding soft tissues to avoid local concentrated force, thereby reducing the impact force acting on the wearer's knee joint.

[0037] The second anti-collision pad 5 includes a second memory foam layer 501, and a TPU skeleton layer 502 is provided inside the second memory foam layer 501. The memory foam layer has a slow rebound characteristic so that it is slowly compressed when subjected to continuous pressure, such as when the back of the knee is lightly touched during squatting, and rebounds quickly after the pressure disappears, avoiding movement jams caused by rigid support. The TPU skeleton layer 502 is embedded in the second memory foam layer 501 to provide basic support force to prevent the second anti-collision pad 5 from excessively collapsing or shifting during exercise. Through the composite structure of memory foam and high-rebound TPU skeleton, while ensuring impact resistance, it has excellent deformation following ability, so that the second anti-collision pad 5 does not affect the wearer's normal squatting, going up and down stairs and other daily bending movements.

[0038] Connecting belts 404 are fixedly installed on both sides of the first crash pad 4 and the second crash pad 5, and a fixing strip 405 is fixedly installed on one side of the connecting belt 404. Two connecting blocks 101 are provided on the front and rear sides of the outer surface of the knee pad body 1 and on the left and right sides of the knee pad body 1.

[0039] A fixing hole 102 is provided on one side of the interior of the connecting block 101, and silicone pads 103 are fixedly installed on both sides of the inner wall of the fixing hole 102. When the fixing bar 405 is inserted into the fixing hole 102, the silicone pad 103 will be squeezed by the fixing bar 405 and deformed, thereby increasing the friction force, so that the fixing bar 405 can be more stably located in the fixing hole 102.

[0040] A driving cavity 104 is provided on one side of the interior of the connecting block 101, and a limiting rod 106 is slidably connected to the interior of the driving cavity 104. One end of the limiting rod 106 extends to the interior of the fixing hole 102. Two springs 105 are fixedly installed on one side of the interior of the driving cavity 104, and the limiting rod 106 is located on one side inside the driving cavity 104 and is fixedly connected to the two springs 105. When the limiting rod 106 moves toward the interior of the driving cavity 104, it will squeeze the two springs 105.

[0041] A movable cavity 108 is provided inside the connecting block 101, and a connecting rod 107 is slidably connected inside the movable cavity 108. One side of the connecting rod 107 extends to the inside of the driving cavity 104 and is fixedly connected to the limit rod 106. A guide hole 110 is provided on the inner top surface of the movable cavity 108. A shift block 109 is fixedly installed on one side of the connecting rod 107 located inside the movable cavity 108, and the shift block 109 extends to the outside of the connecting block 101 through the guide hole 110. A limiting hole 403 is provided on one side of the fixing bar 405. When the wearer manually pushes the shift block 109 to move along the guide hole 110, it will drive the connecting rod 107 and the limit rod 106 to move.

[0042] When installing the first anti-collision pad 4 and the second anti-collision pad 5, the wearer manually pushes the shift block 109 to move along the guide hole 110, so that the limit rod 106 moves toward the inside of the driving cavity 104, and at the same time the limit rod 106 squeezes the two springs 105, and then the fixing bar 405 is inserted into the fixing hole 102. During the insertion process, the silicone pad 103 will be squeezed by the fixing bar 405 and deformed, thereby increasing the friction. When the fixing bar 405 is fully inserted into the fixing hole 102, the wearer releases the shift block 109, and the squeezed spring 105 will push the limit rod 106 to reset, so that the limit rod 106 is inserted into the limit hole 403 of the fixing bar 405. Then repeat this step to complete the installation of the first anti-collision pad 4 and the second anti-collision pad 5.

[0043] Therefore, the first crash pad 4 and the second crash pad 5 can be installed and disassembled. After long-term use, the first crash pad 4 and the second crash pad 5 can be disassembled for cleaning or replacement.

[0044] The outer surface of the kneepad body 1 is provided with protective strips 1022 on both sides of the knee joint. The protective strips 1022 include a skin-friendly and breathable layer 1043. The skin-friendly and breathable layer 1043 is made of medical-grade thermoplastic polyurethane. When worn, it directly contacts the skin, provides a skin-friendly touch, and reduces friction discomfort during exercise.

[0045] An elastic buffer layer 1041 is fixedly installed on the outer surface of the skin-friendly and breathable layer 1043, and a memory alloy mesh 1042 is provided inside the elastic buffer layer 1041. The elastic buffer layer 1041 is made of a blend of spandex and polyester fibers. The spandex provides high elasticity and adapts to the length changes during flexion and extension of the knee joint. The polyester fiber enhances the durability of the base material to avoid fiber breakage due to frequent stretching during exercise. It also adopts oblique cross-weaving to be consistent with the overall 45° direction of the protective strip 1022 to disperse the force and improve the overall elastic uniformity.

[0046] The memory alloy mesh 1042 embedded in the elastic buffer layer 1041 provides rigid support to ensure ligament protection under lateral torsion.

[0047] The interior of the kneepad body 1 is also provided with a memory alloy mesh 1042, which is not evenly covered but has a density and a weaving direction adjusted according to biomechanical zoning to achieve tightness where it should be tight and looseness where it should be loose.

[0048] The wire mesh density in the patellar area is the highest. It is woven along the annular direction of the patella and fits closely with the annular support area 1021 around the patella, directly participating in the dynamic stability of the patellar trajectory. The wire mesh density in the ligament attachment area is second highest. It is woven at a 45° angle along the direction of the ligament and cooperates with the 45° oblique weaving pattern to enhance torsional resistance. The wire mesh density in the popliteal fossa and the outside of the tibial plateau is the lowest. The weaving direction is consistent with the stretching direction of the thigh and calf muscles to avoid hindering the normal flexion and extension of the joint. The wire mesh density at the junction of the patellar area and the ligament area changes gradually to avoid stiffness caused by local stress concentration.

[0049] The memory alloy wire mesh 1042 in the kneepad body 1 and the memory alloy wire mesh 1042 in the protective strip 1022 are both made of nickel-titanium alloy, and the metal wires at the nodes are in direct contact, forming natural conduction.

[0050] Two angle sensors 3 are provided on one side of the outer surface of the kneepad body 1. The angle sensor 3 reflects the flexion and extension angle of the knee joint by detecting the change in the distance between the thigh and the calf, and sends an adjustment instruction to the wire mesh. The memory alloy wire mesh 1042 converts the electrical signal of the sensor into mechanical expansion and contraction, and synchronously adjusts the overall tightness of the kneepad. When the knee joint is straightened, the wire mesh contracts and the kneepad is tightened moderately to stabilize the joint. When the knee joint is deeply bent, the wire mesh stretches to avoid excessive compression of the popliteal blood vessels and nerves, while maintaining the support force of the patellar area.

[0051] The kneepad body 1 has a built-in micro rechargeable battery as the power source for the angle sensor 3, and the thigh strap 2 of the kneepad body 1 is integrated with a wireless charging coil, which can be charged contactlessly via a mobile phone or a dedicated charging base.

[0052] The working principle of the present invention is as follows: the wearer manually pushes the shift block 109 to move along the guide hole 110, so that the limiting rod 106 moves toward the inside of the driving cavity 104, and at the same time the limiting rod 106 squeezes the two springs 105, and then the fixing bar 405 is inserted into the fixing hole 102. During the insertion process, the silicone pad 103 will be squeezed by the fixing bar 405 and deformed, thereby increasing the friction. When the fixing bar 405 is fully inserted into the fixing hole 102, the wearer releases the shift block 109, and the squeezed spring 105 will push the limiting rod 106 to reset, so that the limiting rod 106 is inserted into the limiting hole 403 of the fixing bar 405. Then repeat this step to complete the installation of the first anti-collision pad 4 and the second anti-collision pad 5.

[0053] When the knee joint is subjected to a momentary impact, the anti-collision pad disperses the impact force through a layered buffering mechanism. The memory foam layer absorbs the impact energy through material deformation, prolongs the action time, and reduces the peak pressure. The EVA bottom layer 402 uses the elastic deformation of the material to further absorb energy, while evenly spreading the remaining impact force to the surrounding soft tissues to avoid local concentrated force, thereby reducing the impact force acting on the wearer's knee joint.

[0054] The angle sensor 3 reflects the flexion and extension angle of the knee joint by detecting the change in the distance between the thigh and the calf, and sends adjustment instructions to the wire mesh. The memory alloy wire mesh 1042 converts the electrical signal of the sensor into mechanical expansion and contraction, and synchronously adjusts the overall tightness of the knee pad. When the knee joint is straightened, the wire mesh contracts and the knee pad is tightened moderately to stabilize the joint. When the knee joint is deeply bent, the wire mesh stretches to avoid excessive compression of the popliteal blood vessels and nerves, while maintaining the support force of the patellar area.
