[0024] In related technologies, a helmet is a protective gear used to protect the head. Helmets can be categorized into different types based on their application, such as a sports helmet 10. Furthermore, since users wear the sports helmet 10 during exercise, in addition to ensuring the user's head safety, the sports helmet 10 also needs to have high breathability.

[0025] The main structure of the sports helmet 10 includes an outer shell 100 and an inner liner 400. The inner liner 400 is disposed inside the outer shell 100, and both the outer shell 100 and the inner liner 400 are provided with ventilation holes, which can improve the breathability of the sports helmet 10. However, existing sports helmets 10 have the problem of low structural strength. To address this, this application proposes a sports helmet 10.

[0026] Please refer to Figure 1 and Figure 2 In some embodiments, the sports helmet 10 includes an outer shell 100 and an inner liner 400. The outer shell 100 is provided with a storage cavity and a first ventilation hole 200. The outer shell 100 may be hemispherical in shape, and its shape may be adapted to the user's head. The outer shell 100 may be made of ABS engineering plastic, which gives the sports helmet 10 high cost-effectiveness and impact resistance. The outer shell 100 may also be made of PC polycarbonate, which gives the sports helmet 10 lightweight and high strength. In addition, the outer shell 100 may also be made of carbon fiber composite material, which gives the sports helmet 10 lighter weight and higher impact resistance. The inner liner 400 is disposed in the storage cavity. The inner liner 400 may be made of expanded polystyrene (EPS) or similar high-density foam materials. The inner liner 400 may also be made of novel cushioning materials such as WaveCel honeycomb structure, which can absorb energy through deformation upon impact, reducing the impact force on the head. The inner liner 400 is provided with a second ventilation hole 500, and the first ventilation hole 200 and the second ventilation hole 500 are connected. Specifically, the outer shell 100 is made of a high-strength material to withstand the initial impact, while the inner liner 400 is made of a softer material to further reduce the impact force, thus allowing the sports helmet 10 to better protect the user. After the first ventilation hole 200 and the second ventilation hole 500 are connected, air from the outside of the sports helmet 10 can enter the user's head, thereby improving the breathability of the sports helmet 10. Furthermore, along the depth direction of the first ventilation hole 200, the wall of the first ventilation hole 200 extends into and covers the wall of the second ventilation hole 500. Specifically, the outer shell 100 has a storage cavity and a first vent 200, and the inner liner 400 is disposed in the storage cavity. The inner liner 400 has a second vent 500, and the first vent 200 and the second vent 500 are connected. This can improve the breathability of the sports helmet 10. Along the depth direction of the first vent 200, the wall of the first vent 200 extends into and covers the wall of the second vent 500. This allows the outer shell 100 to further protect the inner liner 400, improving the strength of the sports helmet 10. In essence, the sports helmet 10 can have high strength.

[0027] Furthermore, the shape of the first vent 200 can be circular, elliptical, rectangular, square, honeycomb, rhomboid, fan-shaped, teardrop-shaped, star-shaped, petal-shaped, grid-shaped, or any combination of two of the above shapes, such as a combination of a circle and a rectangle. The shape of the second vent 500 can be circular, elliptical, rectangular, square, honeycomb, rhomboid, fan-shaped, teardrop-shaped, star-shaped, petal-shaped, grid-shaped, or any combination of two of the above shapes, such as a combination of a circle and a rectangle.

[0028] Furthermore, as mentioned above, along the depth direction of the first vent 200, the wall of the first vent 200 extends into and covers the wall of the second vent 500. Specifically, the first vent 200 covers the wall of the second vent 500 in the following manner. For example, in some embodiments, the wall of the first vent 200 partially covers the wall of the second vent 500. Specifically, the wall of the first vent 200 partially covering the wall of the second vent 500 means that the wall of the first vent 200 covers one-sixth, one-fifth, one-quarter, one-third, or one-half of the wall of the second vent 500, which can improve the overall strength of the sports helmet 10. In addition, after the wall of the first vent 200 covers the wall of the second vent 500, the outer shell 100 can also protect the second vent 500.

[0029] Furthermore, the wall of the first vent 200 mentioned above partially covers the wall of the second vent 500. The covering of the second vent 500 by the first vent 200 can also take other forms. Specifically, in some embodiments, the wall of the first vent 200 completely covers the wall of the second vent 500. Specifically, the complete coverage of the second vent 500 by the wall of the first vent 200 means that the depth of the wall of the first vent 200 is greater than or equal to that of the second vent 500, which can improve the overall strength of the sports helmet 10. In addition, after the wall of the first vent 200 completely covers the wall of the second vent 500, the outer shell 100 can also protect the second vent 500.

[0030] Furthermore, in some embodiments, along the depth direction of the first vent 200, the dimension by which the wall of the first vent 200 covers the wall of the second vent 500 is A, where 2mm ≤ A ≤ 30mm. Specifically, A can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, or 30mm, or any value between any two of the above. When A is less than 2mm, the dimension by which the wall of the first vent 200 covers the wall of the second vent 500 is too small, which will result in lower strength of the sports helmet 10. When A is greater than 30mm, the wall of the first vent 200 covers the wall of the second vent 500 by too much, which will lead to material waste.

[0031] Furthermore, in some embodiments, the wall thickness of the first vent 200 is B, where 2mm ≤ B ≤ 30mm. Specifically, B can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, or 30mm, or any value between any two of the above. When B is less than 2mm, the wall thickness of the first vent 200 is the same as the thickness of the outer shell 100, resulting in a too small thickness of the outer shell 10, which leads to lower strength of the sports helmet 10. When B is greater than 30mm, the thickness of the outer shell 100 is too large, which leads to material waste.

[0032] Further, please refer to Figure 2In some embodiments, the inner liner 400 is provided with a first groove 600, and the outer shell 100 is provided with a second groove 300, which is disposed within the first groove 600. Specifically, after the outer shell 100 is provided with the second groove 300 and the inner liner 400 is provided with the first groove 600, the design of the second groove 300 can improve the strength of the outer shell 100, giving it higher strength. Furthermore, the inclusion of the first groove 600 in the inner liner 400 can also improve the overall strength of the sports helmet 10. It should be added that the second groove 300, embedded in the first groove 600, can also improve the assembly accuracy of the outer shell 100 and the inner liner 400, effectively preventing relative displacement during movement. Simultaneously, the second groove 300, embedded in the first groove 600, can also increase the contact area between the inner liner 400 and the outer shell 100, improving the bonding strength.

[0033] Furthermore, in some embodiments, multiple first grooves 600 and second grooves 300 are provided, with each first groove 600 corresponding to one second groove 300. Specifically, there may be two, three, four, five, six, seven, eight, nine, ten, twenty, thirty, forty, or fifty first grooves 600, etc. The design of multiple first grooves 600 can improve the strength of the inner lining 400. Similarly, there may be two, three, four, five, six, seven, eight, nine, ten, twenty, thirty, forty, or fifty second grooves 300, etc. The design of multiple second grooves 300 can improve the strength of the outer shell 100.

[0034] Although it is mentioned above that the first groove 600 can have two, three, four, five, six, seven, eight, nine, ten, twenty, thirty, forty, or fifty, the number of the first groove 600 is not limited to this. The number of the first groove 600 can also be fifty-one, fifty-five, sixty, sixty-five, seventy, seventy-five, eighty, eighty-five, ninety, or one hundred, etc., which will not be elaborated further here. Similarly, although it is mentioned above that the second groove 300 can have two, three, four, five, six, seven, eight, nine, ten, twenty, thirty, forty, or fifty, the number of the second groove 300 is not limited to this. The number of the second groove 300 can also be fifty-one, fifty-five, sixty, sixty-five, seventy-five, eighty, eighty-five, ninety, or one hundred, etc., which will not be elaborated further here.

[0035] Furthermore, the shapes of the first groove 600 and the second groove 300 can be M-shaped, U-shaped, V-shaped, triangular, trapezoidal, or square. For details, please refer to... Figure 2In some embodiments, the cross-sections of the first groove 600 and the second groove 300 are both V-shaped. The V-shaped design of the first groove 600 and the second groove 300 reduces localized stress concentration and improves the impact resistance of the sports helmet 10.

[0036] Furthermore, in some embodiments, multiple first vents 200 and second vents 500 are provided, with each first vent 200 corresponding to one second vent 500. Specifically, there may be two, three, four, five, six, seven, eight, nine, ten, twenty, thirty, forty, or fifty first vents 200, etc. There may also be two, three, four, five, six, seven, eight, nine, ten, twenty, thirty, forty, or fifty second vents 500, etc. The design of multiple first vents 200 and multiple second vents 500 can effectively improve the breathability of the sports helmet 10, ensuring ventilation in all areas of the sports helmet 10 and effectively preventing the user's head from becoming stuffy. In addition, the corresponding arrangement of each first vent 200 and a second vent 500 ensures that after the airflow enters from the first vent 200 of the outer shell 100, it can directly act on the head through the second vent 500 of the inner liner 400, reducing the detour loss of airflow inside the helmet and improving ventilation efficiency.

[0037] Although the number of first vent holes 200 mentioned above can be two, three, four, five, six, seven, eight, nine, ten, twenty, thirty, forty, or fifty, the quantity of first vent holes 200 is not limited to this. The quantity of first vent holes 200 can also be fifty-one, fifty-five, sixty, sixty-five, seventy, seventy-five, eighty, eighty-five, ninety, or one hundred, etc., which will not be elaborated further here. Similarly, although the number of second vent holes 500 mentioned above can be two, three, four, five, six, seven, eight, nine, ten, twenty, thirty, forty, or fifty, the quantity of second vent holes 500 is not limited to this. The quantity of second vent holes 500 can also be fifty-one, fifty-five, sixty, sixty-five, seventy, seventy-five, eighty, eighty-five, ninety, or one hundred, etc., which will not be elaborated further here.

[0038] Furthermore, in some embodiments, the inner liner 400 and the outer shell 100 are bonded together. Specifically, the adhesive used to bond the inner liner 400 and the outer shell 100 can be a polyurethane adhesive, an acrylic adhesive, an epoxy resin adhesive, a modified epoxy-polyurethane hybrid adhesive, or a hot melt adhesive, etc. Bonding the outer shell 100 and the inner liner 400 together facilitates processing and manufacturing, and effectively saves costs.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
