Description

Technical Field

[0001] The utility model relates to the technical field of sports pneumatic helmets, in particular to a lightweight and breathable sports pneumatic helmet. Background Art

[0002] Sports aerodynamic helmets are the most solid protective barrier for life during cycling. Falling during cycling can cause great damage to the head. Even if the cyclist is riding at a lower speed along a bike path with a smooth slope, safety issues cannot be ignored. Medical research has found that wearing a helmet while riding a bicycle can prevent 85% of head injuries and greatly reduce the degree of injury and accident mortality.

[0003] Chinese patent publication number CN218418600U discloses a new type of safety breathable helmet. When wearing the helmet body while riding, the outside air enters the interior of the helmet body through the air inlet slots and can be smoothly discharged from the helmet body through the side ventilation slots, the bottom ventilation slots and the upper ventilation slots, thereby achieving a ventilation effect. Several groups of frames with successively increasing heights are provided inside the air inlet slots. The frames at the same level are integrally formed and injection-molded inside the helmet body. The arrangement of the frames and their internal integration into the helmet body not only solves the problem of structural instability of the helmet body caused by an increase in ventilation area, but also increases impact resistance and effectively enhances the protection of the head.

[0004] The above technology increases the ventilation performance of the helmet without significantly affecting the strength of the helmet. However, the strength and toughness of the conventional built-in frame are average and the weight is heavy, which makes it difficult to reduce the overall weight of the helmet, affecting the riding experience. In addition, the layout of the hollow structure is not reasonable, making it difficult to maximize the impact resistance of the helmet. For this reason, the utility model discloses a lightweight and breathable sports pneumatic helmet to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a lightweight and breathable sports pneumatic helmet to solve the problem in the above background technology that traditional sports pneumatic helmets are difficult to achieve a balance between ventilation performance and impact resistance.

[0006] To achieve the above objectives, the present invention solves the above technical problems as follows:

[0007] A lightweight, breathable sports pneumatic helmet comprises a helmet body and a Kevlar frame completely enclosed within the helmet body. The outer wall of the helmet body is covered with a helmet shell made of a layer of PC material. The Kevlar frame is centrally arranged at the forehead of the helmet body. At least one main wind tunnel is arranged on the helmet body and within the gaps in the Kevlar frame. A plurality of side wind tunnels are symmetrically arranged on both sides of the helmet body. An exhaust hole unit is provided on the rear side of the helmet body for guiding airflow entering the main wind tunnel and the side wind tunnel to pass through with low wind resistance.

[0008] As a further solution of the present invention, a plurality of linear grooves are provided on the outer wall of the helmet body.

[0009] As a further solution of the present invention, the exhaust hole unit includes a main air hole located on the central axis of the helmet body and two side air holes located on both sides of the main air hole, and a hollow logo indicating the brand of the helmet is integrally formed in the main air hole.

[0010] As a further solution of the present invention, the area on the helmet body and located between the side wind tunnel and the side air hole is a reinforcement portion without any ventilation structure.

[0011] As a further solution of the present invention, the Kevlar frame and the helmet body made of EPS material are integrally formed.

[0012] As a further solution of the present invention, the thickness of the helmet shell is between 0.3-0.7 cm.

[0013] As a further solution of the present invention, the inner wall of the helmet body is provided with a recessed flow channel for guiding the airflow from the main wind tunnel or the side wind tunnel into the main air hole or the side air hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model discloses a lightweight and breathable sports pneumatic helmet. The Kevlar frame located at the forehead is integrally formed with the helmet body. When the helmet body is hit, the local impact force is dispersed to the surrounding area, thereby avoiding or reducing head injuries. This compensates for the defect of reduced structural strength caused by the large number of ventilation structures provided at the front and rear of the helmet body. By embedding the Kevlar frame made of Kevlar material within the helmet made of EPS material, the wind tunnel area can be maximized while ensuring the strength of the helmet, thereby ensuring the ventilation effect of the helmet and further contributing to reducing the weight of the helmet. In combination with the lower density EPS material, the thinner outer helmet shell and the lighter Kevlar frame, the helmet is lightweight while maintaining its strength, thereby achieving a two-way improvement in performance and quality.

[0016] The utility model discloses a lightweight and breathable sports pneumatic helmet. The arrangement of a main wind tunnel, side wind tunnels and exhaust hole units improves the breathability of the helmet, reduces the feeling of stuffiness when worn, helps to guide airflow, reduces wind resistance, and improves comfort when worn and smoothness during exercise. A hollow logo integrally formed with the helmet body is arranged in the main air hole, so that the tail of the helmet has both breathability and brand recognition, and is also more aesthetically pleasing. On the other hand, a solid structure reinforcement portion is retained in the rear area of ​​the sports pneumatic helmet, which avoids a further decrease in the structural strength of the sports pneumatic helmet and can cooperate with the Kevlar frame to better bear the force.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] See also Figure 1-4 The utility model provides a lightweight and breathable sports pneumatic helmet, comprising a helmet body 1 and a Kevlar frame 2 completely wrapped in the helmet body 1. The outer wall of the helmet body 1 is covered with a helmet shell 3 made of a layer of PC material, and the thickness of the helmet shell 3 is between 0.3 and 0.7 cm.

[0025] Specifically, the thinner helmet shell 3 helps to reduce the overall weight of the helmet, making the helmet lighter and also combining aesthetics with practicality.

[0026] Furthermore, the Kevlar frame 2 is centrally arranged at the forehead position of the helmet body 1, and the Kevlar frame 2 and the helmet body 1 made of EPS material are integrally formed;

[0027] Specifically, the Kevlar frame 2 is tightly combined with the helmet body 1 to form a solid overall structure, which can effectively disperse the impact force when hit and reduce direct damage to the head. The one-piece molding process reduces the assembly process, simplifies the production process, improves production efficiency, and reduces manufacturing costs.

[0028] Furthermore, at least one main wind tunnel 11 is provided on the helmet body 1 and in the gap of the Kevlar frame 2;

[0029] Specifically, the main wind tunnel 11 is located in the gap of the Kevlar frame 2, which can maximize the area of ​​the wind tunnel, improve the ventilation efficiency inside the helmet, reduce the wearer's feeling of stuffiness when riding, and reduce the use of materials without sacrificing the strength of the helmet, thereby reducing the weight of the helmet and improving wearing comfort. It is worth noting that the Kevlar frame 2 is a frame-like structure that is narrow at both ends and wide in the middle. A plurality of reinforcing columns are fixed between the two sides of the frame structure, and gaps are reserved between adjacent reinforcing columns.

[0030] Furthermore, a plurality of side wind tunnels 12 are symmetrically arranged on both sides of the helmet body 1;

[0031] Specifically, the side wind tunnel 12 can increase the cross-sectional area of ​​the wind tunnel, thereby increasing the air circulation inside the helmet, enhancing breathability, reducing the wearer's feeling of stuffiness, and enhancing riding comfort.

[0032] Furthermore, the rear side of the helmet body 1 is provided with an exhaust hole unit 13 for guiding the airflow entering the main wind tunnel 11 and the side wind tunnel 12 to pass through with low wind resistance. The exhaust hole unit 13 includes a main air hole 131 located on the central axis of the helmet body 1 and two side air holes 132 located on both sides of the main air hole 131. A hollow logo 133 indicating the brand of the helmet is integrally formed in the main air hole 131.

[0033] Specifically, the main air holes 131 and the side air holes 132 can effectively guide the airflow through the helmet, improve ventilation efficiency, reduce the feeling of stuffiness when worn, and improve the wearer's comfort. This not only enhances brand recognition, but also makes the brand logo more eye-catching and beautiful, which helps to enhance the brand image.

[0034] Furthermore, a plurality of linear grooves 14 are provided on the outer wall of the helmet body 1;

[0035] Specifically, the linear groove 14 helps to maintain the smoothness and dynamism of the overall appearance of the helmet, thereby improving the strength and aesthetics of the product.

[0036] Furthermore, the area on the helmet body 1 between the side wind tunnel 12 and the side air hole 132 is a reinforcement portion 15 without any ventilation structure.

[0037] Furthermore, the presence of the reinforcement portion 15 increases the width of the solid material on the side of the helmet, thereby improving the structural strength of the side of the helmet body 1, which helps to better protect the rider's head when impacted. Without affecting ventilation, the helmet body 1 still has sufficient protection capabilities.

[0038] Furthermore, the inner wall of the helmet body 1 is provided with a recessed flow channel 16 for guiding the airflow from the main wind tunnel 11 or the side wind tunnel 12 into the main air hole 131 or the side air hole 132;

[0039] Specifically, generally speaking, the straight-line distance between the main wind tunnel 11 and the main air hole 131 is the shortest, and the recessed flow channel 16 set between the main wind tunnel 11 and the main air hole 131 can effectively guide the airflow into the main wind tunnel 11. Similarly, the straight-line distance between the side wind tunnel 12 and the side air hole 132 is the shortest, and the recessed flow channel 16 set between the side wind tunnel 12 and the side air hole 132 can effectively guide the airflow into the side wind tunnel 12, which can not only enhance the ventilation performance of the helmet, but also significantly reduce the wind resistance of the helmet. It is worth noting that the position setting of the recessed flow channel 16 is not limited to the above-mentioned distribution method, and is intended to achieve the purpose of guiding the main wind tunnel 11 or the side wind tunnel 12 to pass through the exhaust hole unit 13 with low wind resistance.

[0040] Working principle: When the helmet is put on, the airflow in the main wind tunnel 11 and the side wind tunnel 12 passes through the main air holes 131 and the side air holes 132 with low wind resistance, thereby ensuring ventilation of the head.
