Description

Technical Field

[0001] The present application relates to the technical field of sports protection equipment, and particularly to an anti-impact protection sheet structure. Background Art

[0002] Currently, in modern sports, in order to protect athletes from injuries, various protection equipment is often required. Among them, the anti-impact protection sheet structure can effectively reduce the harm caused by external impact forces to the human body. However, traditional protection sheets often have a balance problem between hardness and comfort. If the protection sheet is too hard, it may cause physical discomfort or even injury, while if the protection sheet is too soft, it may not provide sufficient protection function. In addition, traditional protection sheets are usually relatively thick, resulting in relatively poor air permeability and sweat absorption effects, which will seriously affect the comfort and performance of athletes during long-term and high-intensity sports. Utility Model Content

[0003] In order to improve the follow-up performance of the anti-impact protection sheet structure on the premise of ensuring anti-impact performance, the present application provides an anti-impact protection sheet structure.

[0004] The anti-impact protection sheet structure provided by the present application adopts the following technical solutions:

[0005] An anti-impact protection sheet structure includes a buffer layer formed in an ergonomic shape and an anti-impact layer provided on one side of the buffer layer, and a plurality of Y-shaped holes are arranged on the anti-impact layer.

[0006] By adopting the above technical solutions, the buffer layer is used to fit with the body of the exerciser, the anti-impact layer is mainly used to absorb impacts, and the Y-shaped holes can provide a deformation space for bending in two directions, namely inward and outward, to improve the follow-up performance of the anti-impact layer and the buffer layer or the human body during exercise.

[0007] Optionally, the sizes of the Y-shaped holes are all equal. Each Y-shaped hole has three strip-shaped holes with equal lengths and a center point. One end of each strip-shaped hole intersects at the center, and the included angles between adjacent two strip-shaped holes are equal and are 120°.

[0008] By adopting the above technical solutions, the Y-shaped holes with equal sizes and regular shapes can, on the one hand, make the bending performance of the anti-impact layer the same at all angles, and on the other hand, facilitate air permeability and reduce the discomfort of the human body.

[0009] Optionally, the directions of a plurality of the Y-shaped holes are the same. For any one of the plurality of Y-shaped holes, the three strip-shaped holes respectively point to the center points of three different Y-shaped holes adjacent to this Y-shaped hole. The three strip-shaped holes of this Y-shaped hole correspond to the three different adjacent Y-shaped holes one by one. The distances from the ends of the three strip-shaped holes of this Y-shaped hole far from the center point of this Y-shaped hole to the center points of the corresponding Y-shaped holes are all equal, and this distance is less than the length of the strip-shaped hole.

[0010] By adopting the above technical solution, the closely arranged Y-shaped holes can further improve the bending performance of the impact-resistant layer, thereby increasing the follow-up performance of the impact-resistant layer and the buffer layer or the human body during movement. At the same time, it is also convenient to absorb impacts and is conducive to the diffusion and absorption of external loads.

[0011] Optionally, the buffer layer includes a double-density foam layer, and the double-density foam layer has a laminated surface layer and an inner layer, and the density of the surface layer is greater than that of the inner layer.

[0012] By adopting the above technical solution, it can not only provide a certain impact-resistant protection force through the surface layer, but also ensure the comfort of the wearer through the inner layer.

[0013] Optionally, the surface layer is provided with a fixing groove for fixing the impact-resistant layer, and the fixing groove penetrates through the surface layer of the double-density foam layer.

[0014] By adopting the above technical solution, the surface layer can improve the impact-resistant performance by embedding the impact-resistant layer, and also makes the overall structure more stable and firm, extending the service life of the protective sheet structure.

[0015] Optionally, the buffer layer is provided with ventilation holes, and the ventilation holes correspond to the Y-shaped holes one by one.

[0016] By adopting the above technical solution, the ventilation holes corresponding to the Y-shaped holes one by one can improve the overall ventilation performance of the protective sheet structure, enabling the wearer's body to directly contact the air through the ventilation holes and the Y-shaped holes, and improving the comfort of the wearer.

[0017] Optionally, a water-absorbing cloth is provided on one side of the inner layer away from the surface layer.

[0018] By adopting the above technical solution, the water-absorbing cloth can absorb the sweat secreted on the skin surface of the wearer during exercise, reducing the discomfort of the wearer.

[0019] Optionally, the water-absorbing cloth is connected to the inner layer by high-temperature lamination.

[0020] By adopting the above technical solution, the high-temperature lamination connection directly connects the water-absorbing cloth to the inner layer, improving the ventilation performance.

[0021] Optionally, the material of the impact-resistant layer is tpe or eva.

[0022] By adopting the above technical solution, tpe or eva has good buffering and earthquake-resistant performance.

[0023] Optionally, the ergonomic shape is designed based on any one of the shapes of the human coccyx, the human chest, the human back, or the human knee.

[0024] By adopting the above technical solution, the buffer layer can adapt to different parts of the wearer's body, so as to fit the wearer's body and reduce discomfort.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The Y-shaped holes can provide deformation space for bending in both the inner and outer directions, improving the follow-up performance of the impact-resistant layer and the buffer layer or the human body during movement;

[0027] 2. The combination of Y-shaped holes and ventilation holes increases the overall ventilation area of the protective sheet structure, enhances the ventilation effect, and improves the comfort of the user. Brief Description of the Drawings

Detailed Description of the Embodiments

[0035] The following will further describe the present application in detail with reference to the Figure 1-6 drawings.

[0036] Embodiment 1 of the present application discloses an impact-resistant protective sheet structure.

[0037] Embodiment 1

[0038] As Figure 1 and Figure 2As shown in the figure, the anti-impact protection sheet structure includes a buffer layer 1 formed in an ergonomic shape and an anti-impact layer 2 provided on one side of the buffer layer 1. A strap groove 106 may be provided in the buffer layer 1 for positioning the strap, and the strap is used to fix the anti-impact protection sheet structure to the wearer. A plurality of Y-shaped holes 201 are arranged on the anti-impact layer 2, and ventilation holes 105 corresponding to the Y-shaped holes 201 one by one are provided on the buffer layer 1.

[0039] The buffer layer 1 is used to closely fit with the wearer's body as a benchmark, aiming to provide basic support; while the anti-impact layer 2 focuses on absorbing the impact force generated during exercise to ensure sports safety. The Y-shaped hole 201 structure significantly enhances the follow-up performance between the anti-impact layer 2 and the buffer layer 1 or the human body during exercise by providing a bending deformation space in two dimensions, namely, inward and outward, thereby improving the overall sports experience and protection effect.

[0040] As Figure 1-Figure 3 shown in the figure, in this embodiment, the ergonomic shape is designed based on the shape of the human back. The material of the anti-impact layer 2 is EVA. The EVA material is softer than the TPE material. Since the buffer layer 1 needs to fit with the human back, the contact area is relatively large. Using the EVA material has less impact on the follow-up performance of the buffer layer 1 and can reduce the discomfort of the wearer. Since the buffer layer 1 needs to fit with the human back and the contact area is relatively large, a ventilation groove 104 matching the human spine can be provided on the side of the buffer layer 1 away from the anti-impact layer 2. The ventilation groove 104 can effectively reduce the stuffy feeling on the back when wearing the protection sheet for a long time and improve the comfort. In addition, the design of the ventilation groove 104 can also reduce the weight of the anti-impact protection sheet structure to a certain extent, so that the wearer will not feel too heavy during exercise or long-term work.

[0041] As Figure 1 shown in the figure, in addition, in order to provide additional protection for the coccyx, the part of the buffer layer 1 close to the coccyx may not be provided with the anti-impact layer 2, but instead, an anti-impact protection sheet structure with a buffer layer 1 designed based on the shape of the human coccyx is fixed thereon.

[0042] As Figure 1As shown, specifically, the sizes of the Y-shaped holes 201 are all equal. The Y-shaped hole 201 has three strip-shaped holes with equal lengths and a center point. One end of each strip-shaped hole intersects at the center, and the included angles between adjacent strip-shaped holes are equal and 120°. The directions of multiple Y-shaped holes 201 are the same. For any one of the multiple Y-shaped holes 201, the three strip-shaped holes respectively point to the center points of three different adjacent Y-shaped holes 201. The three strip-shaped holes of this Y-shaped hole 201 correspond one by one to the three different adjacent Y-shaped holes 201. The distances from the ends of the three strip-shaped holes of this Y-shaped hole 201 that are far from the center point of this Y-shaped hole 201 to the center points of the corresponding Y-shaped holes 201 are all equal, and this distance is less than the length of the strip-shaped hole.

[0043] The Y-shaped hole 201 structure and arrangement not only have geometric symmetry and regularity, but also in the actual application scenario, the design of the Y-shaped holes 201 in the impact-resistant layer 2 can reduce the overall weight of the impact-resistant protection sheet structure. Its design with consistent and regular Y-shaped holes 201 not only ensures the uniform bending performance of the impact-resistant layer 2 in all directions, but also optimizes the air permeability, effectively reducing the discomfort of the human body. In addition, the three strip-shaped holes of each Y-shaped hole 201 all point to the center of the adjacent Y-shaped hole 201, and this layout enhances the stability and impact resistance of the overall structure. This characteristic not only strengthens the bending performance of the impact-resistant layer 2, but also improves its followability with the buffer layer 1 or the human body during movement. At the same time, it is also beneficial to the absorption of impact force and the uniform diffusion of external load, thereby enhancing the protection efficiency of the overall structure.

[0044] As Figure 1 shown, the buffer layer 1 includes a dual-density foaming layer. The dual-density foaming layer has a laminated surface layer 101 and inner layer 102, and the density of the surface layer 101 is greater than that of the inner layer 102. The double-layer structure formed by the dual-density foaming of the buffer layer 1 can not only provide a certain impact-resistant protection force through the surface layer 101, but also ensure the comfort of the wearer through the inner layer 102.

[0045] As Figure 1As shown in the figure, in order to position the impact-resistant layer 2 relative to the buffer layer 1, the surface layer 101 is provided with a fixing groove 103 for fixing the impact-resistant layer 2. The fixing groove 103 penetrates through the surface layer 101 of the double-density foaming layer. The impact-resistant layer 2 is embedded in the surface layer 101 and fixed to the inner layer 102 by glue, which can not only improve the impact resistance performance but also make the overall structure more stable and firm, and extend the service life of the protective sheet structure. Correspondingly, the ventilation holes 105 are provided in the inner layer 102, and the ventilation holes 105 in the inner layer 102 correspond to the Y-shaped holes 201 one by one. In this embodiment, since the impact-resistant layer 2 is not provided in the part of the buffer layer 1 close to the coccyx, the ventilation holes 105 in this part are provided in both the inner layer 102 and the surface layer 101 at the same time, and the ventilation holes 105 in this part can cooperate with the ventilation holes 105 of the impact-resistant protective sheet structure having the buffer layer 1 designed based on the shape of the human coccyx.

[0046] As Figure 3 shown in the figure, a water-absorbing cloth 3 is provided on the side of the inner layer 102 away from the surface layer 101, and the water-absorbing cloth 3 is connected to the inner layer 102 by high-temperature lamination. The water-absorbing cloth 3 can absorb and disperse excess liquid to keep the wearer dry and comfortable. In traditional processes, the water-absorbing cloth 3 is usually connected to other structures by glue, which will cause a glue layer to be generated between the water-absorbing cloth 3 and other structures, so that the liquid absorbed by the water-absorbing cloth 3 cannot evaporate in time, causing discomfort to the wearer. The high-temperature lamination connection enables the water-absorbing cloth 3 to be directly connected to the inner layer 102, improving the air permeability, so that the moisture absorbed by the water-absorbing cloth 3 can directly contact the air through the ventilation holes 105 and the Y-shaped holes 201, facilitating the evaporation of the moisture absorbed by the water-absorbing cloth 3. On the other hand, the high-temperature lamination connection enables the water-absorbing cloth 3 to be directly connected to the inner layer 102, facilitating cleaning, so that the cleaning water flow can pass through the water-absorbing cloth 3 and flow out along the ventilation holes 105 and the Y-shaped holes 201.

[0047] Example 2

[0048] As Figure 4 shown in the figure, the difference between this embodiment and Embodiment 1 is that the ergonomic shape is designed based on the shape of the human coccyx, and the material of the impact-resistant layer 2 is tpe. Since during the movement of the wearer, the follow-up performance requirement of the coccyx part for the impact-resistant protective sheet structure is relatively low, a tpe material with a higher hardness and stronger impact resistance ability compared with the eva material can be used as the impact-resistant layer 2 to protect the coccyx.

[0049] Example 3

[0050] As Figure 5As shown, the difference between this embodiment and embodiment 1 is that the ergonomic shape is designed based on the shape of the human chest, and the material of the impact-resistant layer 2 is EVA. Since the buffer layer 1 needs to fit the human chest during the wearer's movement, resulting in a large contact area, and since the chest cavity of the human body rises and falls during breathing, the follow-up performance requirements of the anti-impact protective sheet structure are relatively high, so the EVA material, which is softer than the TPE material, can be used as the impact-resistant layer 2 to protect the chest. At the same time, in order to further improve the follow-up performance of the anti-impact protective sheet structure with the rise and fall of the chest cavity, the impact-resistant layer 2 can be designed as two symmetrical parts. In order to further protect the hip joint, the buffer layer 1 and the impact-resistant layer 2 can also extend from the chest to the hip joint.

[0051] Example 4

[0052] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the ergonomic shape is designed based on the shape of the human knee, and the material of the impact-resistant layer 2 is TPE. Since the knee is the most vulnerable part in the statistics of sports injuries, the impact resistance of the impact-resistant protective sheet structure is required to be high, so TPE material with higher hardness and stronger impact resistance than EVA material can be used as the impact-resistant layer 2 to protect the knee. At the same time, during exercise, as the wearer bends and stretches his knees, the buffer layer 1 will scrape against the calf. In order to reduce the discomfort caused by the scraping, the part of the buffer layer 1 close to the calf can be provided with a tortoise scale structure 4, thereby improving the follow-up performance with the wearer's calf.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
