Description

Technical Field

[0001] This utility model relates to the field of helmet technology, and in particular to a displaceable cushioning liner structure for reducing helmet impact injuries. Background Technology

[0002] The helmet liner is an important component of a helmet, mainly serving to cushion, provide comfort, ensure breathability, and keep warm. It can effectively absorb and disperse external impacts, reducing injury to the head. At the same time, its good breathability and moisture-wicking properties can prevent the head from feeling stuffy and smelly.

[0003] Chinese Patent Publication No. CN216796645U discloses a helmet liner with heat absorption, shock absorption, and energy absorption effects. It is installed inside a helmet and includes at least one liner panel. Each liner panel comprises a fabric layer at its base, a cushioning layer above the fabric layer with shock absorption and energy absorption effects, a gel layer above the cushioning layer with heat absorption effects, and a thin film layer above the gel layer and connected to the fabric layer to completely enclose the cushioning layer and gel layer. The cushioning layer is made of a material with non-Newtonian fluid properties. This invention has a simple and reasonable structure, making it particularly suitable for summer use. It achieves good helmet protection through the shock absorption and energy absorption effects of the non-Newtonian fluid-like cushioning layer, while the gel layer absorbs heat through contact with the wearer's head to ensure a cool feeling on the wearer's head, effectively reducing the stuffiness of wearing a helmet and improving the wearing experience.

[0004] The above-mentioned technology achieves shock absorption and heat absorption effects by combining multiple materials. The complex structural design increases the production cost of the inner lining structure, making it unsuitable for widespread use. Utility Model Content

[0005] The purpose of this invention is to provide a displaceable cushioning liner structure for reducing helmet impact injuries, thereby solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems:

[0007] A displaceable cushioning liner structure for mitigating helmet impact injuries, comprising:

[0008] The bottom layer, one side of which is connected to the inner wall of the helmet;

[0009] The surface layer is located in the area of ​​the bottom layer facing the human head. The surface layer is provided with at least one buffer area. The buffer area is recessed from the surface layer away from the bottom layer to form an open cavity or thickened to form a boss structure, so that the buffer area can deform and displace when subjected to external force.

[0010] The buffer area gradually narrows from the surface layer towards the side away from the bottom layer.

[0011] As a further embodiment of this invention, a gap is formed between adjacent buffer areas.

[0012] As a further embodiment of this utility model, the surface layer is made of EVA, EPP, PEBA or PU material.

[0013] As a further embodiment of this invention, the bottom layer is connected to a local area of ​​the helmet's inner wall via Velcro.

[0014] In addition, this utility model also provides a displaceable cushioning liner structure for reducing helmet impact injuries, including the aforementioned structure, and further including:

[0015] The intermediate layer is connected to the bottom layer on one side and is attached to the side of the top layer with an open cavity on the other side, so that the intermediate layer deforms together with the top layer and the bottom layer when subjected to external force.

[0016] As a further embodiment of this utility model, the intermediate layer is made of EVA, EPP, PEBA or PU material.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model discloses a displaceable buffer liner structure for reducing helmet impact injuries. It uses low-density, high-elasticity EVA, EPP, PEBA or PU material as the buffer element. It has the advantage of being lightweight, which can reduce the burden on the head and reduce fatigue. When an external force is applied to the helmet, the buffer area deforms, gradually dispersing the impact force to the surrounding area, avoiding concentrated force, thereby reducing the direct impact on the head.

[0019] This utility model discloses a displaceable buffer liner structure for reducing helmet impact injuries. Upon impact, it forms an "air cushion effect," where the internal air pressure increases instantaneously, generating dynamic buffering force. The open cavity or protrusion structure can increase the deformation threshold of the buffer area, preventing the head from feeling too tight. It can prolong the impact time, reduce the instantaneous impact intensity, and enhance the buffering effect.

[0020] This utility model discloses a movable buffer liner structure for reducing helmet impact injuries. When impacted, the air pressure inside the open cavity changes rapidly. The change in air pressure inside the cavity is similar to an "air cushion". When impacted, the increase in air pressure can provide additional buffering force, thereby prolonging the impact time and reducing the instantaneous impact intensity, so that a single surface layer can also achieve effective buffering.

[0021] This utility model discloses a displaceable buffer liner structure for reducing helmet impact injuries. The buffer element relies on its own elasticity to conform to the shape of the head to a certain extent. The gap between adjacent buffer areas serves as a natural air channel, forming a complete ventilation system that promotes airflow inside the helmet, removes heat and moisture from the head, and makes the helmet more comfortable to wear.

[0022] This utility model discloses a displaceable cushioning liner structure for reducing helmet impact injuries. The bottom layer is made of velvet material and is fixed to the nylon hook and loop fastener on the inner wall of the helmet. It can be disassembled by simple pulling, making the liner structure easy to remove and install, and convenient to clean. Attached Figure Description

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1, please refer to Figure 1-3This utility model provides a displaceable cushioning liner structure for mitigating helmet impact injuries, comprising a bottom layer 1 and a top layer 2. The bottom layer 1 is connected to the inner wall of the helmet on one side, and the bottom layer 1 and the helmet are separate structures. The bottom layer 1 can be directly installed inside the helmet, or indirectly installed by connecting the bottom layer 1 to an internal helmet support. The top layer 2 and the bottom layer 1 are bonded and fixed as a single structure to ensure structural stability. The top layer 2 is located in the area of ​​the bottom layer 1 facing the human head and can be installed on the top, side, or forehead of the helmet for precise protection. The top layer 2 has at least one cushioning area 21, which can be designed as a single area or... Designed in multiple ways, the multiple buffer areas 21 are arranged in a certain order, which helps to better distribute the pressure of the helmet on the head. The buffer areas 21 are recessed from the surface layer 2 to the side away from the bottom layer 1 to form an open cavity 211, so that the buffer areas 21 can deform and displace when subjected to external force. The open cavity 211 can deform when subjected to external force, absorbing and dispersing impact energy. This deformation mechanism can significantly prolong the impact time and reduce the instantaneous impact intensity. It is worth noting that the design of the open cavity 211 also takes into account breathability. When the buffer area 21 is under pressure, it can promote the flow of air inside the helmet and remove heat and moisture from the head.

[0033] Furthermore, the buffer area 21 gradually narrows from the surface layer 2 toward the side away from the bottom layer 1, and the buffer area 21 has a triangular structure with chamfered edges.

[0034] Specifically, the gradually narrowing buffer zone 21 can deform more easily when subjected to external force, thereby more effectively absorbing and dispersing impact energy;

[0035] Specifically, the stability of the triangle allows the buffer area 21 to better maintain its shape when subjected to external forces, while the design of the apex of the triangle can more effectively disperse the impact force.

[0036] Specifically, the chamfered structure reduces friction and pressure on the head from the edge of the buffer area 21, avoiding discomfort caused by prolonged wear or impact, and significantly improving wearing comfort.

[0037] Furthermore, a gap is formed between adjacent buffer areas 21;

[0038] Specifically, the gaps, acting as air channels, promote airflow inside the helmet, carrying away heat and moisture generated by the head, thus keeping the head dry and comfortable. Good breathability can significantly reduce the stuffiness when wearing a helmet for a long time and improve the wearing experience. It is worth noting that the buffer areas 21 are arranged in an array, and the gaps between adjacent buffer areas 21 are interconnected, forming a grid-like ventilation channel, which effectively enhances the helmet's heat dissipation performance.

[0039] Specifically, the gap allows each buffer zone 21 to deform independently, avoiding mutual interference between adjacent buffer zones 21, and each buffer zone 21 can effectively absorb and disperse the impact force.

[0040] Furthermore, the surface layer 2 is made of EVA, EPP, PEBA, or PU material;

[0041] Specifically, EVA, EPP, PEBA, or PU materials have excellent cushioning and shock absorption properties. They can deform when subjected to external impact, absorbing and dispersing impact energy, thereby effectively reducing the direct impact on the head. EVA, EPP, PEBA, or PU materials are soft and elastic, conforming to the shape of the head and providing a comfortable wearing experience, reducing discomfort caused by prolonged wear. In addition, EVA, EPP, PEBA, or PU materials have a certain degree of breathability, which can promote airflow inside the helmet, carrying away heat and moisture from the head, making the helmet more comfortable to wear.

[0042] Furthermore, the bottom layer 1 is connected to a local area of ​​the inner wall of the helmet via Velcro;

[0043] Specifically, the bottom layer 1 is made of velvet and is fixed to the Velcro surface of the helmet's inner wall. It can be easily removed by pulling, making the inner lining structure easy to disassemble and install, and convenient to clean. The partial connection method allows the bottom layer 1 to have some room to move when subjected to external force, so as to better deform in coordination with the top layer 2 and the middle layer 3, further dispersing the impact force and enhancing the overall cushioning effect.

[0044] Example 2, please refer to Figure 4 and Figure 5 Unlike Embodiment 1, the buffer area 21 is recessed from the surface layer 2 toward the side away from the bottom layer 1 to form an open cavity 211 or is thickened to form a boss structure 212, so that the buffer area 21 can deform and displace when subjected to external force.

[0045] In this embodiment, the boss structure 212 provides more buffer space by increasing the material thickness, which can absorb more impact energy, so that the local buffer thickness reaches 5 mm-6 mm, which can maintain good buffer performance after multiple uses and repeated impacts, and extend the service life of the inner lining structure.

[0046] Example 3, please refer to Figure 6 Unlike embodiment 1, it also includes an intermediate layer 3, one side of which is connected to the bottom layer 1, and the other side is attached to the side of the surface layer 2 with an open cavity 211, so that the intermediate layer 3 deforms together with the surface layer 2 and the bottom layer 1 when subjected to external force.

[0047] In this embodiment, the intermediate layer 3 is fixedly connected to the surface layer 2 and the bottom layer 1 by adhesive bonding to ensure the stability of the structure. The intermediate layer 3 not only increases the buffer thickness, allowing the impact force to be dispersed over a larger range, but also further seals the open cavity 211. When subjected to external force, the air pressure inside the cavity will rise rapidly, similar to an "air cushion," providing additional buffering force. This design not only prolongs the duration of the impact force but also reduces the instantaneous impact intensity.

[0048] Furthermore, the intermediate layer 3 is made of EVA, EPP, PEBA, or PU material;

[0049] Specifically, the thickness of the middle layer 3 is not less than 1 mm. When an external force is applied to the helmet, the middle layer 3 can work together with the surface layer 2 and the bottom layer 1 to disperse the impact force and further improve the cushioning effect.
