Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of protective appliance, especially a helmet with a composite inner lining. BACKGROUND

[0002] As an important safety protection product, helmets are widely used in transportation, sports, industry and other fields, and its main role is to protect the wearer's head from injury when subjected to external impact. The helmet is usually composed of an outer shell, a buffer layer and an inner lining. Among them, the material selection and structure design of the buffer layer and the inner lining play a key role in the protection performance and wearing comfort of the helmet.

[0003] At present, the commonly used material for the helmet lining is expanded polystyrene (EPS), which has the advantages of light weight and good cushioning performance. EPS material can absorb and disperse energy when subjected to impact through foaming molding process, thereby reducing the injury to the head. However, in the prior art, the EPS lining is usually directly foamed and molded in the helmet shell, which has some disadvantages. On the one hand, the overall weight of the helmet is still heavy, which can easily cause fatigue to the wearer after a long time of wearing; on the other hand, although the cushioning performance of EPS material is good, its protection strength still needs to be further improved under high energy impact.

[0004] In addition, some existing helmets use a combination of plastic brackets and EPS material, which can improve the structural strength of the helmet to some extent, but such structure often requires complex production process, and still has limitations in reducing weight and enhancing protection strength.

[0005] Therefore, how to reduce the weight of the helmet while further enhancing the protection strength of the helmet is a technical problem to be solved in the current helmet design field. SUMMARY

[0006] The utility model discloses in order to solve above -mentioned existing technical problem, provide a kind of helmet with composite inner lining.

[0007] The technical scheme of the utility model is realized as follows:

[0008] A helmet with a composite inner lining, comprising an outer shell, the outer shell is fixedly connected with a protective layer for protecting the head of a user, the protective layer comprises a filler layer and a composite layer, the outer wall of the filler layer is attached to the inner wall of the outer shell, and a cavity for accommodating the composite layer is reserved at the part where the filler layer and the outer shell are attached.

[0009] Further, the connecting surface of the composite layer and the filler layer is provided as a smooth surface or a concave-convex surface, and the maximum thickness of the composite layer is less than the thickness of the filler layer.

[0010] Furthermore, the composite layer is made of a composite material, and the composite layer and the filler layer are bonded together by hot melt bonding or secondary molding.

[0011] Furthermore, a soft pad is installed at the bottom edge of the outer casing, the top surface of the soft pad is connected to the protective layer, and the shape of the soft pad matches the shape of the lower edge of the outer casing.

[0012] Furthermore, an eye shield is fixedly installed on the outer shell, with one end of the eye shield embedded in the connection between the inner wall of the outer shell and the protective layer.

[0013] Furthermore, a windproof cover is movably connected to the outer shell, with both ends of the windproof cover rotatably connected to the two sides of the outer shell. An adjustment knob for adjusting and fixing the rotation angle of the windproof cover is provided at the connection between the windproof cover and the outer shell.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention increases the overall energy absorption performance of the helmet by reserving a cavity between the filling layer and the outer shell and setting a composite layer between the helmet shell and the filling layer. At the same time, by using composite materials and adjusting the material density to reduce the weight of the product, the user experience is improved. The high performance of the composite materials is used to optimize the overall performance of the helmet, which not only reduces the weight of the helmet, but also enables the helmet to absorb and disperse energy more effectively when it is impacted, thereby improving the protective performance.

[0019] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] likeFigs. 1-2 As shown, a helmet with a composite liner includes an outer shell 1, and a protective layer 2 for protecting the user's head is fixedly connected inside the outer shell 1. The protective layer 2 includes a filling layer 3 and a composite layer 4. The outer wall of a portion of the filling layer 3 is attached to the inner wall of the outer shell 1, and a cavity 5 is reserved at the part where the filling layer 3 and the outer shell 1 are attached to accommodate the composite layer 4.

[0021] In this embodiment, the outer shell 1 is the main structure of the helmet, primarily serving a protective function. It can withstand external impacts, disperse impact forces, and provide support for the protective layer 2. The protective layer 2 consists of a filling layer 3 and a composite layer 4. The filling layer 3 is located inside the outer shell 1, serving as a buffer and energy absorber. It partially fits the outer shell 1 and has a reserved cavity 5 to accommodate the composite layer 4. The filling layer 3, through its material properties such as EPS foam, absorbs impact energy and reduces the direct impact force on the head. At the same time, the reserved cavity 5 provides installation space for the composite layer 4, further optimizing the helmet's structure. The composite layer 4 is the interlayer between the filling layer 3 and the outer shell 1, made of high-performance composite materials, such as lightweight high-energy-absorbing materials. It is bonded to the filling layer 3 through hot-melt bonding or secondary molding. Composite materials typically have a low density, which can significantly reduce the weight of the helmet, and have a higher energy absorption coefficient, which can further absorb and disperse impact energy, enhancing the helmet's protective performance.

[0022] In some embodiments, the composite layer 4 can be made of a lattice structure material, which can significantly reduce the weight of the helmet and improve its ability to absorb impact energy.

[0023] Furthermore, the connection surface between the composite layer 4 and the filling layer 3 is set as a smooth surface or an uneven surface, and the maximum thickness of the composite layer 4 is less than the thickness of the filling layer 3;

[0024] Smooth surfaces reduce friction between materials, facilitating molding and processing while ensuring uniform transmission of impact force. Concave-convex surface design increases the contact area and friction between composite layer 4 and filler layer 3, thereby more effectively dispersing and absorbing energy upon impact. This allows the impact force to be dispersed in multiple directions, reducing local stress concentration and improving the overall protective performance of the helmet. Specifically, concave-convex surfaces can enhance the bonding strength between composite layer 4 and filler layer 3 by increasing mechanical interlocking, further improving the structural stability of the helmet.

[0025] Furthermore, the composite layer 4 is made of composite material, and the composite layer 4 and the filler layer 3 are bonded together by hot melt bonding or secondary molding.

[0026] Furthermore, a soft pad 6 is installed at the bottom edge of the outer shell 1. The top surface of the soft pad 6 is connected to the protective layer 2, and the shape of the soft pad 6 matches the shape of the lower edge of the outer shell 1.

[0027] Furthermore, an eye shield 7 is fixedly installed on the outer shell 1, with one end of the eye shield 7 embedded in the connection between the inner wall of the outer shell 1 and the protective layer 2; the eye shield 7 can protect the wearer's eyes from external factors such as splashes, sandstorms, and ultraviolet rays.

[0028] Furthermore, a windproof cover 8 is movably connected to the outer shell 1. The two ends of the windproof cover 8 are rotatably connected to both sides of the outer shell 1. An adjustment knob 9 for adjusting and fixing the rotation angle of the windproof cover 8 is provided at the connection between the windproof cover 8 and the outer shell 1.

[0029] The windproof cover 8 can effectively block the direct wind, reduce wind noise, and improve the wearer's comfort during high-speed movement or harsh environments. By adjusting the knob 9, the wearer can adjust the angle of the windproof cover 8 as needed to achieve personalized protection.

[0030] In some embodiments, the adjustment knob 9 is typically provided with several locking teeth inside or connected to it. These locking teeth mesh with the support structure of the windproof cover 8, such as gears or arc-shaped toothed plates. When the user turns the windproof cover 8, the angle change of the windproof cover 8 is fixed at a certain position through the meshing relationship of the locking teeth.

[0031] In this embodiment, the outer shell 1 serves as the main structure, bearing external impacts and dispersing the impact force. The filling layer 3 in the protective layer 2 absorbs impact energy through its material properties, reducing the direct impact force on the head. The composite layer 4 further absorbs and disperses impact energy using its high-performance composite material, enhancing the protective performance. The connection surface between the composite layer 4 and the filling layer 3 is designed as a smooth surface or an uneven surface, and is combined with hot-melt bonding or secondary molding to optimize energy transfer and structural stability.

[0032] The soft padding strip 6 in this utility model can provide additional cushioning and comfort, the eye shield 7 and the windproof cover 8 provide eye protection and wind protection respectively, and the windproof cover 8 is fixed at the required angle by adjusting the knob 9 to ensure the safety and comfort of the wearer in different environments.

[0033] Through the synergistic effect of the outer shell 1 and the protective layer 2, the helmet achieves multi-level absorption and dispersion of impact force. At the same time, the high-performance material of the composite layer 4 is used to reduce the weight of the helmet and improve its protective performance. The concave-convex design further enhances the bonding strength between the composite layer 4 and the filling layer 3 and optimizes energy absorption efficiency. The additional functions of the eye shield 7 and the windproof visor 8 enhance the practicality and adaptability of the helmet. The overall design aims to provide a lightweight helmet with high protective performance and a good wearing experience.

Those skilled in the art should understand that the embodiments and descriptions above are merely illustrative of the principles of the utility model.
