Description

Technical Field

[0001] This utility model belongs to the field of sports protective gear technology, and in particular relates to a protective gear for extreme sports. Background Technology

[0002] In today's booming sports industry, the importance of sports protective gear as key equipment for ensuring athlete safety is self-evident. As people's demands for sports experience and safety protection continue to rise, technological innovation in sports protective gear is also constantly advancing. It has gradually evolved from traditional, simple protective equipment into high-performance products that integrate various advanced materials and design concepts. Early sports protective gear mostly used ordinary fabrics and rubber, providing only basic cushioning and friction protection. Today, however, various new materials such as silicone and carbon fiber are widely used, resulting in significant progress in lightweight and high-strength protection.

[0003] Existing sports protective gear primarily absorbs and disperses impact by incorporating flexible padding, elastic layers, or support structures in key protective areas. It commonly uses foam materials such as rubber, EVA, silicone, and polyurethane, and enhances its protective effect through multi-layer composites, localized thickening, or embedded skeleton designs. This type of protective gear provides a certain level of cushioning and comfort during general sports activities and offers good protection in ordinary environments. However, extreme sports, such as skiing, skateboarding, rock climbing, and BMX, are highly challenging and stimulating. In these high-intensity, high-impact scenarios, athletes are often subjected to extreme conditions including high-speed movement, falls from heights, and violent collisions. Participants face a higher risk of injury during these activities, thus placing higher demands on sports protective gear: it must not only possess excellent impact resistance and abrasion resistance but also ensure dynamic fit, wearing comfort, and adaptability to extreme environments.

[0004] For example, Chinese patent CN102872579A discloses a sports protective gear. This design employs a multi-layered composite structure. The outer layer is made of a relatively strong and wear-resistant material to improve scratch resistance, while the inner layer uses a soft material to enhance skin comfort. Thick padding layers are incorporated in specific areas to enhance the absorption of localized impacts, making it suitable for elbow and knee joint safety protection in extreme sports such as roller skating, cycling, and skateboarding. However, with the continuous improvement of extreme sports technology and the diversification of scenarios, existing protective gear structures still have the following problems in practical use: First, regarding impact absorption capacity, the cushioning structure of existing protective gear mostly uses traditional foam materials such as ordinary EVA and PU, and its energy absorption method mainly relies on the compression and rebound characteristics of the material itself. When facing the instantaneous high-intensity impact load during extreme sports (such as high-speed falls, weightlessness, etc.), the energy absorption rate and cushioning efficiency of traditional foam layers are limited, and they are prone to insufficient cushioning, deformation and collapse, etc., making it difficult to effectively protect vulnerable parts such as bones and joints from injury. Second, regarding structural dynamic adaptability, most existing protective gear is molded as a single piece, providing strong structural continuity but weak flexibility and lacking a detailed response mechanism to the dynamic patterns of joint movements. In extreme sports, the elbows, knees, wrists, and other joints need to frequently perform complex movements such as flexion, extension, rotation, and abduction. The rigid structure of the protective gear can easily create points of constraint, leading to limited movement for the wearer and even inducing secondary injuries.

[0005] Furthermore, extreme sports are often accompanied by complex external environments such as high temperatures, extreme cold, humidity, and intense friction. Existing protective gear mostly adopts traditional thermoforming structures or multi-layer adhesive structures, which are prone to problems such as interlayer delamination, surface wear, and edge cracking. Especially in humid or low-temperature environments, the material properties fluctuate greatly, leading to a decrease in the protective performance of the protective gear, a worse wearing experience, and even material failure, resulting in safety hazards.

[0006] Therefore, there is an urgent need for high-performance protective gear specifically designed for extreme sports to fill the market gap and meet the higher safety requirements of extreme sports enthusiasts. Utility Model Content

[0007] This invention aims to solve the problems of insufficient cushioning and energy absorption, poor structural adaptability, and poor comfort of existing sports protective gear in extreme sports scenarios. It discloses a special protective gear for extreme sports with a multi-layered cushioning structure, modular symmetrical arrangement, and high-performance material combination. By constructing a multi-level protection system including a protective cover, a cushioning pad, and elastic protective units, it utilizes an integrated molded foam elastic structure and high-performance D3O material to work together, and introduces a symmetrical arrangement of multiple protruding units and a spacer groove design to significantly improve the impact force dispersion ability and wearing comfort, achieving a stable protective effect under high-intensity sports conditions.

[0008] This utility model provides protective gear for extreme sports, comprising: The protective gear itself is used to be worn over and on the body to protect specific parts. The protective device includes an elastic protective unit, a protective cover, and a buffer pad layer. The elastic protective unit is provided with a first elastic protrusion unit, and a first receiving groove is provided on the first elastic protrusion unit that is recessed toward the side away from the protective cover. The protective cover is fastened and installed on the outside of the elastic protective unit. A protective cover plate is provided on the protective cover that protrudes toward the side away from the elastic protective unit. A second receiving groove is provided in the protective cover plate. The buffer pad layer is received and fixed between the first receiving groove and the second receiving groove and is covered and fixed by both. A connecting structure is used to secure the protective device to the body of the protective gear, and the protective cover is disposed on the outer side of the body of the protective gear.

[0009] In a preferred embodiment of this application, the elastic protective unit includes a connecting plate, the first elastic protrusion unit is disposed on the connecting plate and is disposed toward the side close to the protective cover, and the second receiving groove of the protective cover is nested on the outer edge of the first elastic protrusion unit.

[0010] In a preferred embodiment of this application, the buffer pad is integrally formed from D3O material, and the thickness of the buffer pad is H. The distance between the upper edge of the first receiving groove near the protective cover and the bottom plate of the first receiving groove is L, where H > L.

[0011] In a preferred embodiment of this application, the thickness H of the buffer pad is slightly less than the sum of the depths of the second receiving groove and the first receiving groove.

[0012] In a preferred embodiment of this application, the elastic protective unit is integrally manufactured from a supercritical physical foaming material, and the elastic protrusion base plate of the first elastic protrusion unit is disposed on the side of the connecting plate away from the protective cover.

[0013] In a preferred embodiment of this application, a plurality of second elastic protrusion units are provided in the first receiving groove, and a spacer groove is provided between two adjacent second elastic protrusion units.

[0014] In a preferred embodiment of this application, the thickness of the second elastic protrusion unit is less than the depth of the first receiving groove, and the buffer pad extends into the side of the first receiving groove and is configured to cooperate with the second elastic protrusion unit.

[0015] In a preferred embodiment of this application, the protective cover includes a connecting cover plate, which is disposed corresponding to the connecting plate body, and the protective cover plate is disposed on the connecting cover plate and protrudes toward the side away from the elastic protective unit.

[0016] In a preferred embodiment of this application, an arc-shaped transition portion is provided on the outer periphery of the protective cover on the side away from the elastic protective unit.

[0017] In a preferred embodiment of this application, the connecting tissue is any one or more combinations of adhesive, suture, or thermo-pressed connecting structures.

[0018] Compared with existing technologies, the protective gear for extreme sports described in this utility model has the following advantages: This application constructs a composite protective system that absorbs energy layer by layer by incorporating a protective cover, a buffer layer, and an elastic protective unit into the protective gear structure. The outermost protective cover bears and initially disperses the external impact force, while the inner D3O buffer layer rapidly absorbs energy through compression deformation within a double-receiving groove clamping structure. The remaining impact is further dissipated by the supercritical physical foaming elastic unit at the bottom. This layered absorption path achieves efficient energy dissipation and mitigation of the impact force. At the same time, the receiving groove structure limits the deformation path, effectively preventing buffer failure or displacement. This allows the protective gear to maintain structural integrity and high energy absorption efficiency when facing high-speed, instantaneous, and multi-directional impacts during extreme sports, thereby significantly improving the overall impact resistance and protective reliability.

[0024] like Figures 1-7 As shown, this application discloses a protective gear for extreme sports, including... Protective gear body 100, used for wearing on the body to protect the body parts; The protective device 200 includes an elastic protective unit 1, a protective cover 2, and a buffer pad 3. The elastic protective unit 1 is provided with a first elastic protrusion unit 102, and a first receiving groove 103 is provided on the first elastic protrusion unit 102, which is recessed towards the side away from the protective cover 2. The protective cover 2 is fastened and installed on the outside of the elastic protective unit 1. A protective cover plate 202 is provided on the protective cover 2, which is protruded towards the side away from the elastic protective unit 1. A second receiving groove 203 is provided in the protective cover plate 202. The buffer pad 3 is accommodated and fixed between the first receiving groove 103 and the second receiving groove 203 and is covered and fixed by both. A connecting mechanism 300 is used to fix the protective device 200 to the protective gear body 100, and the protective cover 2 is disposed on the protective gear body 100 facing outward.

[0025] This application discloses a protective gear for extreme sports, comprising a protective body 100 disposed on the surface of the protected area of ​​the body, a protective device 200 disposed on its outer side, and a connecting mechanism 300 for achieving a stable connection between the two. The protective device 200 consists of an elastic protective unit 1, a protective cover 2, and a buffer pad 3 sandwiched between the two. The elastic protective unit 1 is provided with a first elastic protrusion 102 having an opening facing the protective cover 2 to form a first receiving groove 103. The first receiving groove 103 is used to embed and position the buffer pad 3. The protective cover 2 is integrally connected or detachably installed on the outside of the elastic protective unit 1, and is provided with an outwardly protruding protective cover plate 202. The inner side of the protective cover plate 202 is provided with a second receiving groove 203, which cooperates with the first receiving groove 103 to clamp the buffer pad 3 in the assembled state, realizing a multi-layered structural fitting and protective combination. The buffer pad 3 is made of a material with good energy absorption properties, such as D3O. The material is designed to deform rapidly upon impact to absorb energy. Simultaneously, the structure of the first elastic protrusion unit 102 provides a second layer of buffer deformation space, and the material's resilience enhances the overall shock absorption process. The connecting structure 300 is constructed using various methods such as stitching, bonding, heat pressing, or fastening to ensure that the entire protective device does not loosen or shift during vigorous movement. This results in a multifunctional protective gear system that is structurally sound, highly energy-efficient, stable, and has good assembly and disassembly adaptability. During use, when the human body is impacted during movement, the protective cover 2 is the first part to contact and bear the impact force. The protective cover 2, through its protective cover plate 202 and internal second receiving groove 203, partially transmits the impact force to the part clamped within it. The buffer pad 3 undergoes controllable deformation along its thickness direction under the bidirectional constraint of the first receiving groove 103 and the second receiving groove 203, absorbing part of the energy and dispersing the impact stress. Subsequently, the residual impact force continues to act on the first elastic protrusion unit 102 in the elastic protective unit 1 located on the outside of the protective gear body 100. This protrusion structure further absorbs and dissipates the impact energy through the elastic deformation of the material itself, while alleviating the risk of injury caused by local pressure concentration. The entire protective process forms a three-level synergistic mechanism of the protective cover 2 blocking, the buffer pad 3 deforming and absorbing energy, and the first elastic protrusion unit 102 buffering again. It is suitable for extreme sports protection scenarios for multiple high-risk parts such as the knee, elbow, calf, and wrist.

[0026] The protective gear disclosed in this application for extreme sports establishes a three-level buffer path through the clamping buffer structure formed between the first elastic protruding unit 102, the buffer pad 3, and the protective cover 2. This allows for the layered and distributed absorption of impact energy when subjected to high-intensity or repetitive impacts, significantly improving the protective performance of the gear in extreme sports scenarios. The combined use of the first receiving groove 103 and the second receiving groove 203 limits the stress area and compression deformation of the buffer pad 3, improving the energy absorption efficiency and stability of the buffer pad 3 and effectively preventing pad displacement or deformation failure. The protective cover 2 is placed on the outermost layer as a rigid barrier to block the impact and wear directly acting on the buffer pad 3 and the protruding unit, extending the service life of the buffer material and elastic structure. At the same time, it avoids wear and damage caused by contact between the protective gear and sports equipment, the ground, etc. The structure is clearly layered and compactly fitted, ensuring both protective performance and comfort and flexibility. Users can receive good protection while freely performing various movements during extreme sports.

[0027] As a preferred example of this application, the elastic protective unit 1 includes a connecting plate 101, and a first elastic protrusion unit 102 is disposed on the connecting plate 101 and facing towards the side near the protective cover 2. The second receiving groove 203 of the protective cover 202 is nested in the outer edge of the first elastic protrusion unit 102. In the example of this application, the connecting plate 101 in the elastic protective unit 1 is disposed outside the contour of the first elastic protrusion unit 102 for connection and fixation with the protective body 100. The first elastic protrusion unit 102 is disposed on the side of the connecting plate 101 facing the protective cover and protrudes in a direction perpendicular to the connecting plate 101. Then, a recessed structure is formed in the first elastic protrusion unit 102 away from the protective cover 2 to form a first receiving groove 103 for accommodating and supporting the buffer pad layer 3. The protective cover 202 is... The protruding structure located on the outside of the protective cover 2 extends away from the elastic protective unit 1, and its internal structure has a second receiving groove 203, which works together with the first receiving groove 103 to define the buffer pad layer 3. The sidewall of the second receiving groove 203 extends inward to the outer edge of the first elastic protruding unit 102, so that the protective cover 202 and the first elastic protruding unit 102 form a fitted and enclosing relationship through the internal receiving groove, thereby forming a buffer protection system that is structurally mutually restrictive and functionally mutually coordinated during use.

[0028] This application introduces a fitting unit with limiting, guiding and supporting functions into the protective structure by setting the first elastic protrusion unit 102 on the connecting plate 101 and making it protrude towards the protective cover 2, and simultaneously using the second receiving groove 203 set in the protective cover 202 to nest and cover the outer edge of the protrusion structure. This allows for the formation of a clearer force transmission path and buffer deformation channel when subjected to impact, effectively avoiding structural instability caused by excessive elastic deformation amplitude or directional deviation during impact, and further enhancing the protective device's ability to dissipate impact force and its tolerance.

[0029] As a preferred example of this application, the buffer pad 3 is integrally formed from D3O material, and the thickness of the buffer pad 3 is H. The distance between the upper edge of the first receiving groove 103 near the protective cover 2 and the bottom plate of the first receiving groove 103 is L, where H > L. In the example of this application, the buffer pad 3 is integrally formed from D3O polymer buffer material, and its overall thickness is H. The first receiving groove 103 provided on the first elastic protrusion unit 102 has a limited depth L, which is defined as the vertical distance between the upper edge of the first receiving groove 103 near the protective cover 2 and its bottom plate, where H is greater than L. This allows the buffer pad 3 to protrude from the first elastic protrusion unit 102 in the installed state. Since the D3O material has the non-Newtonian property of being soft in static conditions and instantly hardening under dynamic impact, its overall configuration can quickly transform into a high-rigidity state to resist impact when encountering external force, and quickly recover to a soft state after the external force is released, thereby achieving continuous buffer protection against multiple impacts. In the example of this application, the ratio of L to H is set to 0.5~0.8, and the thickness H of the buffer pad 3 is slightly less than (e.g., less than 3mm~10mm) the sum of the depths of the second receiving groove 203 and the first receiving groove 103, so that the buffer pad 3 is in a preloaded state after the elastic protective unit 1 and the protective cover 2 are assembled. At the moment the impact force arrives, the internal structure of the D3O material undergoes molecular locking transformation, and the material hardens instantly to form a rapid interception of the impact force. The buffer pad 3 in the compressed state deforms along the direction of the first receiving groove 103, so that it absorbs most of the impact force in a limited space. The energy is neither excessively compressed due to its large size and loses its elasticity, nor insufficient in size and fails to form an effective buffer. After the impact force is initially absorbed, the remaining part further acts on the first elastic protrusion unit 102 below. This structure, supported by the connecting plate 101, produces a slight elastic deformation to further disperse the impact force. When it is finally transmitted to the human body surface, the energy has been greatly weakened, achieving a protective effect. At the same time, the buffer pad layer has a rapid deformation recovery capability due to the D3O material, and can rebound to its original state in a short time, preparing for the next round of impact and ensuring that the protective performance does not weaken during continuous use.

[0030] As a preferred example of this application, the elastic protective unit 1 is integrally prepared from supercritical physical foaming material, and the elastic protrusion base plate 104 of the first elastic protrusion unit 102 is disposed on the side of the connecting plate 101 away from the protective cover 2. In the example of this application, the elastic protective unit 1 is integrally molded using supercritical physical foaming material. The supercritical physical foaming material is formed by processing under conditions close to or exceeding the material's critical temperature and critical pressure. It has a uniform and dense internal structure, a high closed-cell rate, and a stable distribution. The foaming process uses physical gas foaming, avoiding chemical residues. It has advantages such as being non-toxic, odorless, lightweight, environmentally friendly, and safe. The connecting plate 101 and the first elastic protrusion unit 102 are made of the same material and are formed in one piece. This not only effectively avoids the mechanical weakness caused by poor interface bonding in traditional splicing structures, but also provides excellent buffering and energy absorption performance through the closed-cell structure of the material. When subjected to force, it can release energy through micropore compression, improving the overall buffering efficiency and impact resistance. Using physical gas foaming instead of chemical foaming processes eliminates the need to add any toxic or irritating chemicals. The product is odorless, does not irritate the skin, and has good biocompatibility and environmental friendliness. The elastic protective unit 1 described in this application is manufactured using a polyolefin elastomer-SEBS elastomer formula. The formula is pure, and a purely physical foaming process is employed, using nitrogen from the air and carbon dioxide collected from industrial waste gas as foaming agents to form numerous micro-nano-level pores within the material. Compared to traditional chemical foaming processes, this method does not use chemical foaming agents or cross-linking agents, resulting in a product with no odor, no formamide or other toxic or harmful residues, 100% safety for skin contact, and excellent energy absorption properties and wearability. Preferably, the elastic protrusion base plate 104 of the first elastic protrusion unit 102 in this application is specially provided on the side away from the protective cover 2 and directly adheres to the human skin. In motion, it can absorb part of the lateral disturbance energy due to skin friction and local deformation. It can also transfer the local impact force to the surrounding tissue through the skin contact surface, thereby reducing the risk of injury caused by concentrated impact. At the same time, the high fit significantly improves the wearing stability, avoids slippage and misalignment, and ensures the continuous and effective operation of the protective structure. The supercritical physical foaming material itself is lightweight and has a certain degree of breathability, which also allows the overall protective gear to maintain strong protective performance without affecting the flexibility of movement and wearing comfort, meeting the dual needs of high-intensity protection and comfortable wearing in extreme sports scenarios.

[0031] As a preferred example of this application, such as Figure 8As shown, a plurality of second elastic protrusion units 105 are provided in the first receiving groove 103, and a spacer groove 106 is provided between two adjacent second elastic protrusion units 105. In the example of this application, by providing a plurality of second elastic protrusion units 105 in the first receiving groove 103, each second elastic protrusion unit 105 is arranged along the width or length direction of the protective gear, and a spacer groove 106 is provided between two adjacent second elastic protrusion units 105, the spacer groove 106 allows each second elastic protrusion unit 105 to be independent of each other in the unloaded state, and to respond to impacts independently in the loaded state without producing deformation behavior that restricts or interferes with each other. The plurality of second elastic protrusion units 105 are all integrally formed of supercritical physical foaming material. It can work together with the upper protective cover 2, the lower elastic protective unit 1, and the buffer pad 3 to form a tiered buffer system, thereby decomposing and absorbing external impacts in layers. At the same time, the setting of the spacer groove 106 not only gives the local structure higher flexibility, but also improves the overall structure's responsiveness and multi-directional adaptability. Multiple second elastic protrusion units 105 are divided into elastic areas by the spacer groove 106, so that the buffer pad 3 can maintain good flexibility and compliance in motion, which helps the wearer maintain the fit and comfort of the protective gear during dynamic processes such as bending, stretching, and turning.

[0032] This application provides multiple second elastic protrusion units 105 within the first receiving groove 103 and spacer grooves 106 between adjacent units. This allows each second elastic protrusion unit 105 to deform independently and buffer independently when subjected to force, improving the rapid response and elastic adjustment capabilities of the entire protection system to local impacts. This multi-zone distributed deformation mechanism effectively reduces the risk of single-point impact caused by concentrated force, and enhances the uniformity and safety of force on multiple moving parts of the human body during vigorous movement. The presence of the spacer grooves 106 ensures that the overall structure maintains high flexibility and fit under different types of impacts such as bending, torsion, and compression, making it less prone to misalignment or displacement, thereby ensuring the stability of the protection device during high-speed changes in movement.

[0033] As a preferred example of this application, the thickness of the second elastic protrusion unit 105 is less than the depth of the first receiving groove 103, and the buffer pad 3 extends into the side of the first receiving groove 103 and is configured to cooperate with the second elastic protrusion unit 105. This structure, by controlling the thickness of the second elastic protrusion unit 105, maintains a reserved gap between the buffer pad 3 and the bottom of the first receiving groove 103 in the uncompressed state, thereby providing compression space for the buffer pad 3. At the same time, a collaborative buffering area is formed through the contact interface between the buffer pad 3 and the second elastic protrusion unit 105. When the protective gear is subjected to external impact during use, the buffer pad 3 is preferentially pressed into the first receiving groove 103 and deforms together with the second elastic protrusion unit 105, absorbing and dispersing the impact energy. The impact force is transmitted from the local area to the surrounding area through the rebound of the second elastic protrusion unit 105, thereby forming a multi-level slow-release mechanism of zoned buffering and staggered absorption, improving the deformation response capability of the overall protective structure.

[0034] As a preferred example of this application, such as Figures 9-13 As shown, multiple second elastic protrusion units 105 are arranged symmetrically along the transverse centerline and / or longitudinal centerline of the connecting plate 101. By constructing a symmetrical structure, the shape of the connecting plate can be adjusted according to the target application area, while maintaining the symmetrical logic of the protrusion unit arrangement. This results in a structure with stronger universal adaptability and uniformity, while also facilitating mold structure standardization, improving overall production efficiency, and reducing processing costs.

[0035] As a preferred example of this application, the second elastic protrusion unit 105 includes a central protrusion 1051 located at the center of the first receiving groove 103. The central protrusion 1051 is symmetrically arranged along at least one centerline of the first receiving groove 103, and a plurality of peripheral protrusions 1052 are symmetrically arranged along the center of the central protrusion 1051 or along a transverse or longitudinal centerline. In the example of this application, the second elastic protrusion unit 105 is set at the center of the first receiving groove 103, and the plurality of peripheral protrusions 1052 are symmetrically distributed with the central protrusion 1051 as the center of symmetry or along the central axis. The second elastic protrusion unit 105 is arranged in a "center-surround" structure. Each protrusion has an independent deformation space when subjected to force, and local deformation and linkage energy absorption are achieved through the elastic response mechanism of the material. The centrally symmetrical layout of the overall structure helps to maintain the force balance in all directions, which is suitable for scenarios where protective gear is subjected to multi-directional impacts from different moving parts such as elbows, knees, and legs.

[0036] As a preferred example of this application, the projected contours of the peripheral protrusion 1052 and / or the central protrusion 1051 within the first receiving groove 103 are one or more combinations of arc, circle, polygon, ellipse, and fan shape. This application uses a reasonable combination of different geometric contours distributed within the space of the first receiving groove 103, so that each protrusion has both the characteristics of smooth curved transitions and balanced force distribution in its structural form, and the ability to form responsive support in a specific direction. Spacing grooves 106 are provided between the protrusions, each having its own independent deformation space. Through the optimization of the above-mentioned contour structure and shape combination, the adaptability and deformation efficiency of the protective gear during the cushioning process are improved without increasing material consumption, making it suitable for dynamic cushioning response requirements in multi-angle impact scenarios.

[0037] As a preferred example of this application, the spacing groove 106 includes a plurality of first spacing grooves 1061 and a plurality of second spacing grooves 1062, wherein the first spacing grooves 1061 and the second spacing grooves 1062 are arranged in a cross shape. In the example of this application, the spacer slot 106 is composed of a plurality of first spacer slots 1061 and a plurality of second spacer slots 1062. The plurality of first spacer slots 1061 and second spacer slots 1062 are arranged intersectingly, and the overall distribution is in a grid-like, staggered, or other geometrically intersecting structure. The number, direction, width, and depth of the first spacer slots 1061 and second spacer slots 1062 can be flexibly adjusted according to the stress requirements, structural dimensions, and functional layout of the specific protected parts. In a preferred case, the first spacer slots 1061 are arranged along the longitudinal or transverse direction of the first receiving slot 103, and the second spacer slots 1062 are arranged at a certain angle to the first spacer slots 1061. The two sets of spacer slots together reasonably divide the plurality of second elastic protrusion units 105 into relatively independent buffer units. The overall structural layout is regular and rich in layers, with good flexibility, dynamic adaptability, and three-dimensional buffer partitioning effect, further enhancing the overall protective capability, structural stability, and wearing comfort of the protective gear, and improving the functionality and aesthetics of the product.

[0038] As a preferred example of this application, the protective cover 2 includes a connecting cover plate 201, which is correspondingly disposed with the connecting plate body 101. The protective cover plate 202 is disposed on the connecting cover plate 201 and protrudes toward the side away from the elastic protective unit 1. In the example of this application, the protective cover 2 is composed of the connecting cover plate 201 and the protective cover plate 202. The connecting cover plate 201 serves as a fixed support to stably connect the protective cover 2 to the outside of the protective gear body 100. The protective cover plate 202 is disposed on the connecting cover plate 201 and protrudes toward the side away from the elastic protective unit 1. A second receiving groove 203 is formed on its side close to the elastic protective unit 1. The second receiving groove 203 is correspondingly disposed with the buffer pad layer 3 in terms of spatial position and external outline to realize a nested protective structure for the buffer pad layer 3.

[0039] As a preferred example of this application, an arc-shaped transition portion 204 is provided on the outer periphery of the protective cover 202 on the side away from the elastic protective unit 1. In this example, the outer periphery edge of the protective cover 202 on the side away from the elastic protective unit 1 is provided with an integrally extended arc-shaped transition portion 204. The arc-shaped transition portion 204 has a smooth curved surface shape and is distributed around the edge of the protective cover 202. It is naturally connected to the main body of the protective cover 202 without obvious sharp corners or abrupt structures, avoiding the formation of sharp edges or pressure points. Without affecting the protection range and protection effect, it reduces friction, snagging or discomfort when in contact with the human body, clothing or sports equipment, while improving the overall safety and comfort of the protective gear. The arc-shaped structure gives the overall appearance smooth lines and enhances the aesthetics of the product.

[0040] As a preferred example of this application, the connecting structure 300 is any one or more combinations of adhesive, stitching, or thermocompression connection structures. In the example of this application, the connecting structure 300 is used to reliably connect the protective body 100 and the protective device 200. The connecting structure 300 includes any one or more combinations of adhesive, stitching, or thermocompression connection structures. The specific connection method is flexibly selected according to the material characteristics, structural layout, and actual usage requirements of the protective body 100 and the protective device 200. The adhesive structure uses a high-performance adhesive to smoothly bond different components. The stitching structure uses high-strength stitches to penetrate the connection part to form a stable mechanical connection. The thermocompression connection structure uses heating and pressure to fuse or deform the materials at the connection part, forming a dense and firm bond. The three methods can be used individually or in combination to ensure the stability of the overall structure, meet different process conditions and usage requirements, improve the structural strength of the knee brace, wearing comfort, and production efficiency, and ensure the reliability and durability of the knee brace product in various sports scenarios. As a preferred example of this application, the elastic protective unit 1 and the protective cover 2 in the protective device 200 clamp and fix the buffer pad layer 3 and then sew them integrally onto the protective body 100.

[0041] This application discloses a high-performance protective gear structure suitable for extreme sports. A three-tiered protection system is constructed through the coordinated use of a protective cover 2, a buffer layer 3, and an elastic protective unit 1. The outer protective cover 2 uses a protective structure with a hardness greater than that of the elastic protective unit 1 to withstand the initial impact and protect the internal structure from direct wear. The middle buffer layer 3 uses D3O material with instantaneous hardening and resilience properties, achieving rapid energy absorption and dispersion upon impact. The bottom elastic protective unit 1 uses a supercritical physical foaming integrated molding process to form a multi-layered buffer structure, continuing secondary energy dissipation during residual impact transmission, effectively reducing the impact intensity borne by the human body. Simultaneously, multiple independent protrusions and spacer grooves 106 are designed inside the elastic unit, enabling it to exhibit good local deformation. With its capacity and multi-directional buffering response performance, it further enhances the absorption and adaptability to complex impacts. The first receiving groove 103 and the second receiving groove 203 together define and stabilize the position of the buffer pad 3, preventing it from failing due to slippage or force displacement. The overall structure forms an upper and lower clamping relationship, which not only improves the protective stability, but also enhances the consistency of structural assembly and the convenience of disassembly and assembly. In addition, the elastic protruding base plate 104 of the elastic protective unit 1 can directly fit the human skin area, with good fit and wearing stability. The entire protective system takes into account energy absorption efficiency, structural flexibility and dynamic adaptability, and can be widely used in high-risk sports joints such as elbows and knees. While ensuring the flexibility of movement, it significantly improves the safety protection level of users in extreme sports.
