Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of helmet, specifically relates to a riding helmet with sticky layer. BACKGROUND

[0002] With the rapid development of modern traffic, the riding safety accidents occur frequently, and head injury is one of the main reasons causing serious consequences. Among the many safety protection equipment, the riding helmet is particularly important because it directly protects the head, and the safety of the rider in the traffic accident has been the focus of research and development.

[0003] Although the existing riding helmet design has made certain progress in the primary impact protection, for example, by using various cushioning materials and structural designs to absorb and disperse impact force, however, the existing riding helmet often cannot provide sufficient protection when facing secondary impact, resulting in more serious injuries to the rider, therefore, how to improve the protection ability of the riding helmet in the secondary impact has become a problem to be solved in the technical field of helmet. SUMMARY

[0004] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a riding helmet with sticky layer which can improve the secondary protection ability of the helmet when riding.

[0005] In order to solve the above problems, the technical scheme adopted by the utility model is as follows:

[0006] A riding helmet with sticky layer, comprising a helmet body, a sticky layer attached to the outer surface of the helmet body, an outer shell layer provided on the outer side of the sticky layer, an air layer sealed between the outer shell layer and the sticky layer, and a support structure connected between the outer shell layer and the sticky layer, the support structure being uniformly distributed in the form of adhering to the helmet body.

[0007] The outer shell layer and the support structure are made of the same brittle material.

[0008] Further, the sticky material in the sticky layer includes reactive adhesive and / or water-based adhesive and / or solvent-based adhesive and / or roll paper adhesive and / or acrylic adhesive and / or silicone adhesive and / or pressure-sensitive adhesive.

[0009] Further, the brittle material includes one or more of polystyrene foam, thin-walled polycarbonate glass fiber and enhanced brittle resin.

[0010] Further, the thickness of the outer shell layer is 0.5-1mm.

[0011] Further, the outer shell layer and the support structure are integrally formed.

[0012] Furthermore, the support structure is cylindrical.

[0013] Furthermore, the supporting structures are more densely distributed in the forehead, top of the head, and back of the head compared to other areas.

[0014] Furthermore, the support structure is connected to the helmet body by a hot-melt adhesive.

[0015] Furthermore, the bottom of the helmet body is provided with a detachable fixing buckle.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes an adhesive layer on the surface of a cycling helmet to prevent secondary impacts. The outer shell layer ensures that, in the absence of impact, the adhesive layer remains unaffected by road debris, dust, or other environmental factors, maintaining the helmet's smooth exterior. This solution can handle unexpected situations in various traffic environments, has a relatively simple overall structure, is easy to use, and has a wide range of applications.

[0022] The present invention will be further described below with reference to specific embodiments.

[0023] like Figures 1-3 As shown, the cycling helmet with an adhesive layer of the present invention includes a helmet body 1, and an adhesive layer 10 is attached to the outer surface of the helmet body 1. The adhesive material of the adhesive layer 10 includes reactive adhesives and / or water-based adhesives and / or solvent-based adhesives and / or roll paper adhesives and / or acrylic adhesives and / or silicone adhesives and / or pressure-sensitive adhesives.

[0024] On the outside of the adhesive layer 10, there is also a shell layer 30, and between the shell layer 30 and the adhesive layer 10, there is an air layer 20, and in the air layer 20, the shell layer 30 and the adhesive layer 10 are connected by a special support structure 40. The support structure 40 is multiple and uniformly distributed in the form of adhering to the helmet body 1.

[0025] Further, the shell layer 30 and the support structure 40 are made of the same brittle material, so that when the helmet collides, the shell layer 30 and the support structure 40 can be broken synchronously. The brittle material includes polystyrene foam and / or thin-walled polycarbonate glass fiber and / or enhanced brittle resin.

[0026] In addition, the thickness of the shell layer 30 is 0.5-1mm, which can be integrally formed with the support structure 40 by molding, injection molding and resin transfer molding.

[0027] In this embodiment, the support structure 40 is cylindrical, with a diameter of 1-5mm, a height of 2-10mm, and a spacing between adjacent support structures of 10-30mm. In the high-risk areas of the forehead, the top of the head and the back of the brain, the diameter of the support structure 40 is increased to 3-5mm, and the spacing is reduced to 10-15mm.

[0028] In this embodiment, the support structure 40 and the helmet body 1 are connected by hot melt adhesion.

[0029] The working principle of the utility model is: when the cycling helmet collides with other objects for the first time, the shell layer 30 and the support structure 40 are broken, and thus during the first collision, the adhesive layer 10 is exposed to the air surface and adheres to the object about to collide, thereby preventing the head from being subjected to secondary collision.

[0030] In other aspects, the bottom of the helmet body 1 is also provided with a detachable fixing buckle 50, and the user can quickly detach the helmet after the collision through the quick-release fixing buckle, thereby improving the protection effect of secondary damage.

[0031] In this embodiment, the thickness of the air layer 20 is less than the thickness of the adhesive layer 10 by 1-5mm, which is the best in this range.

[0032] In the patent US11484083B, there is also a design related to the shell layer and the adhesive layer, but the difference is that the support structure used in the comparative document is a spring, which is used to reduce shock damage. In this scheme, the support structure is the same fragile material as the shell layer, which is contrary to the purpose of improving strength. Instead, it needs to break after being hit. The shell layer and the support structure in this scheme can be considered as independent of the helmet body 1, which is very different from the comparative document as part of the helmet body.

[0033] Secondly, the role of the adhesive layer 10 in the comparative document is to further reduce the shock wave in cooperation with the spring, while in this scheme, the adhesive material needs to flow out to adhere to the road debris and sundries. Finally, the shell layer in the comparative document is a hard material used as the first layer of protection for the helmet, while in this scheme, the shell layer 30 is only used as a protective layer for the adhesive layer 10 to maintain its adhesion. The essence of this scheme is still to use the adhesive effect of the adhesive layer 10 to prevent secondary impact. In general, both have similar structures, but the essential concept and functional idea are different.
