[0034] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0035] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "left," and "right" are generally used to define the orientation of the accompanying drawings, and "inner" and "outer" refer to the inner and outer parts of the relevant components. Furthermore, terms such as "first" and "second" are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0037] Helmets are safety protection devices for the head, and they are widely used in various industries. During use, helmets will inevitably suffer some damage or dirt, whether on the outside or inside.

[0038] The helmets in the relevant technologies are one-piece helmets, and the top cover of the helmet cannot be removed. When the exterior or interior of the helmet is damaged or soiled, the entire helmet needs to be replaced, resulting in high costs and wasted resources.

[0039] Therefore, such as Figures 1-4 As shown, this disclosure provides a split helmet, including an upper cover 1 and a lower shell 2.

[0040] The upper cover 1 is detachably connected to the lower shell 2.

[0041] The upper cover 1 includes a first cover 11 and a second cover 12. The second cover 12 has a first surface and a second surface that are arranged opposite to each other. The first cover 11 covers the first surface of the second cover 12, and the second surface of the second cover 12 is connected to the lower shell 2.

[0042] The upper cover 1 comprises two parts, namely a first cover 11 and a second cover 12, which are connected face to face.

[0043] In the above technical solution, the first cover 11 and the second cover 12 interact with each other, providing mutual support and strengthening the structure, thereby improving the overall structural strength of the upper cover 1 and enhancing its impact resistance. Furthermore, the detachable connection between the upper cover 1 and the lower shell 2 allows them to be separated. This means that if either the upper cover 1 or the lower shell 2 is damaged or soiled, it can be replaced individually without needing to purchase the entire helmet, reducing helmet purchase costs and minimizing resource waste, thus enabling reuse.

[0044] Optionally, in one embodiment of this disclosure, the lower shell 2 includes a shell 21 and a covering layer 22, with the covering layer 22 covering the top surface of the shell 21, and the second surface of the second cover 12 connected to the covering layer 22. This arrangement improves the structural strength of the lower shell 2, thereby further enhancing the overall structural strength of the split helmet and improving its impact resistance.

[0045] The cover layer 22 covers the top surface of the shell 21, and the cover layer 22 wraps around the top surface of the shell 21, so that the cover layer 22 can provide a cushioning effect when the helmet falls. It can be understood that the cover layer 22 and the second cover 12 are located between the first cover 11 and the shell 21. The first cover 11 is the outermost layer of the entire split helmet, while the shell 21 is the innermost layer of the entire split helmet, and the shell 21 is fitted onto the user's head.

[0046] Optionally, in one embodiment of this disclosure, the second surface of the second cover 12 is provided with an assembly part 13, and the top surface of the cover layer 22 is provided with a mating part 23. The assembly part 13 and the mating part 23 are connected, and the mating of the assembly part 13 and the mating part 23 can restrict the relative movement of the second cover 12 and the cover layer 22. The assembly part 13 and the mating part 23 facilitate the assembly and positioning of the second cover 12 and the cover layer 22, enabling rapid installation while preventing relative movement between them, thus ensuring the reliability and stability of the entire split helmet. Furthermore, the assembly part 13 strengthens the structure of the second cover 12, and the mating part 23 strengthens the structure of the cover layer 22, thereby improving the structural strength of the second cover 12 and the cover layer, further enhancing the overall structural strength of the split helmet and its impact resistance.

[0047] When the second cover 12 covers the covering layer 22, the assembly part 13 can be connected with the mating part 23. The assembly part 13 and the mating part 23 mutually limit each other, thus restricting the second cover 12 and the covering layer 22. Therefore, the second cover 12 and the covering layer 22 will not move relative to each other. In other words, during the use of the split helmet, the second cover 12 and the covering layer 22 remain in a relatively fixed state, which will not affect the user's use or the impact resistance of the split helmet.

[0048] Optionally, in one embodiment of this disclosure, the assembly part 13 includes a first sub-assembly part 131 and a second sub-assembly part 132, and the mating part 23 includes a first sub-mating part 231 and a second sub-mating part 232.

[0049] The first sub-assembly part 131 is connected to the first sub-mating part 231, and both the first sub-assembly part 131 and the first sub-mating part 231 extend along a first direction. The second sub-assembly part 132 is connected to the second sub-mating part 232, and both the second sub-assembly part 132 and the second sub-mating part 232 extend along a second direction. The first direction and the second direction intersect.

[0050] The first sub-assembly part 131 corresponds to the first sub-fitting part 231, and both extend along a first direction. Through the mutual cooperation of the first sub-assembly part 131 and the first sub-fitting part 231, positioning and restriction functions are achieved in one direction. The second sub-assembly part 132 corresponds to the second sub-fitting part 232, and both extend along a second direction. Through the mutual cooperation of the second sub-assembly part 132 and the second sub-fitting part 232, positioning and restriction functions are achieved in another direction. Thus, positioning and restriction functions in two directions can be achieved, improving the positioning and restriction functions of the second cover 12 and the covering layer 22, and ensuring their mutual fixation.

[0051] Optionally, in one embodiment of this disclosure, one of the assembly part 13 and the mating part 23 is configured as a protrusion, and the other is configured as a groove, with the protrusion engaging in the groove. By engaging the protrusion in the groove, the protrusion contacts the groove wall and bottom, achieving positioning and restraint. The protrusion and groove are also convenient for manufacturing, resulting in low manufacturing costs.

[0052] In some examples, the mounting portion 13 is configured as a protrusion, and the mating portion 23 is configured as a groove. The protrusion is a structure in which the second surface of the second cover 12 protrudes towards the covering layer 22, and the groove is formed by the top of the covering layer 22 being recessed inward in a direction away from the second cover 12. Both the protrusion and the groove are configured as strip-shaped structures.

[0053] Alternatively, in another embodiment of this disclosure, both the assembly portion 13 and the mating portion 23 are configured as protrusions.

[0054] Optionally, in one embodiment of this disclosure, the hardness of the cover layer 22 is less than that of the shell 21. The shell 21 is made of plastic, and the cover layer 22 is made of foamed material. With this arrangement, the cover layer 22 provides cushioning and shock absorption, while the shell 21 provides support, thus supporting the cover layer 22. In some examples, the shell 21 is injection molded from plastic raw materials, while the cover layer 22 is formed by EPS (polystyrene) foaming. By controlling the foaming density of the EPS, the impact resistance of the entire split helmet can be adjusted.

[0055] Optionally, in one embodiment of this disclosure, the second cover 12 is made of foamed material, and the foaming density of the covering layer 22 is different from that of the second cover 12. This arrangement allows for different shock absorption effects between the second cover 12 and the covering layer 22, enabling adjustments to the impact resistance of the split helmet as needed, allowing for localized adjustments. Furthermore, the helmet development cycle can be significantly shortened during manufacturing. After production, the helmet undergoes testing; if the test fails, the foaming density of the second cover 12 or the covering layer 22 can be adjusted based on the test results to modify the cushioning and shock absorption effect. This eliminates the need to modify the mold or adjust the structure of the first cover or lower shell, resulting in a shorter cycle and more convenient manufacturing compared to existing helmets. It should be noted that the foaming density of the covering layer 22 and the second cover 12 refers to the degree of foaming during manufacturing, which can be reflected in the difference in the size of the internal pores.

[0056] Optionally, in one embodiment of this disclosure, a hook 14 is provided on the second surface of the second cover 12, and a buckle 24 is provided on the top surface of the covering layer 22. The hook 14 is connected to the buckle 24. Through the cooperation of the buckle 24 and the hook 14, the second surface of the second cover 12 and the covering layer 22 can be detachably connected, which is convenient to operate and has high connection strength.

[0057] The hook 14 can be hooked into the buckle 24 to achieve connection between the two. In some examples, there can be multiple hooks 14 and buckles 24, which are spaced apart and correspond one-to-one. Multiple hooks 14 are spaced apart along the circumferential edge of the second cover 12, and multiple buckles 24 are spaced apart along the circumferential edge of the cover layer 22. In some examples, the buckles 24 can be connected to the housing 21, and the cover layer 22 does not cover the buckles 24, so that the buckles 24 are exposed from the top surface of the cover layer 22 for connection with the hooks 14.

[0058] Optionally, in another embodiment of this disclosure, the second surface of the second cover 12 and the covering layer 22 are provided with connecting holes. A locking pin can be installed in the connecting hole to connect the second cover 12 and the covering layer 22. The locking pin can be removed from the connecting hole for disassembly. There can be multiple connecting holes, spaced apart and corresponding one-to-one. The multiple connecting holes are spaced apart along the circumferential edge of the second cover 12, and the multiple latches 24 are spaced apart along the circumferential edge of the covering layer 22.

[0059] Optionally, in one embodiment of this disclosure, the hardness of the first cover 11 is greater than that of the second cover 12. The first cover 11 is made of plastic, and the second cover 12 is made of foamed material. With this arrangement, the second cover 12 provides cushioning and shock absorption, while the first cover 11 provides support, thus supporting the second cover 12. In some examples, the first cover 11 is injection molded from plastic raw material, serving as an exterior component and directly contacting the external environment. The second cover 12 is formed by EPS (polystyrene) foaming. By controlling the foaming density of the EPS, the impact resistance of the entire split helmet can be adjusted. Through the dual-layer shock absorption effect of the second cover 12 and the covering layer 22, the impact resistance of the entire split helmet can be improved, and the shock absorption effect of the second cover 12 and the covering layer 22 can be adjusted according to different needs.

[0060] Optionally, in one embodiment of this disclosure, the split helmet includes a first lamp body 3 and a second lamp body 4. In a first direction, the lower shell 2 has a first end and a second end disposed opposite to each other. The first lamp body 3 is connected to the first end of the lower shell 2, and the second lamp body 4 is connected to the second end of the lower shell 2. Illumination in two positions or two directions can be achieved through the first lamp body 3 and the second lamp body 4 to meet different needs.

[0061] In some examples, the first direction is the front-to-back direction of the split helmet. That is, the first end of the lower shell 2 can be the front end, and the first light body 3 is used to illuminate the front. The second end of the lower shell 2 can be the rear end, and the second light body 4 is used to indicate what is behind. Of course, in other examples, the first direction can also be the left-to-right direction of the split helmet, and the first and second ends of the lower shell 2 can be the left and right sides. The first light body 3 and the second light body 4 can be LED lights.

[0062] Optionally, in one embodiment of this disclosure, the split helmet further includes a battery 5 and an electrical connector 6. The top of the lower shell 2 is provided with a first mounting groove 25 and a second mounting groove 26. The battery 5 is connected in the first mounting groove 25, and the electrical connector 6 is connected in the second mounting groove 26. One end of the electrical connector 6 is connected to the battery 5, and the other end of the electrical connector 6 is connected to the first lamp body 3 and the second lamp body 4. The upper cover 1 closes the first mounting groove 25 and the second mounting groove 26.

[0063] The battery 5 is capable of charging and discharging, and it supplies power to the first lamp body 3 and the second lamp body 4. The electrical connector 6 acts as an electrical conductor to provide power. It is understood that the electrical connector 6 extends to and connects to both the first lamp body 3 and the second lamp body 4.

[0064] The first mounting slot 25 can accommodate the battery 5, ensuring that the battery 5 does not interfere with the connection between the upper cover 1 and the lower shell 2. The second mounting slot 26 can accommodate the electrical connector 6, ensuring that the electrical connector 6 does not interfere with the connection between the upper cover 1 and the lower shell 2. In some examples, the electrical connector 6 has a first sub-component and a second sub-component. The first sub-component is connected to the first lamp body 3, and the second sub-component is connected to the second lamp body 4. The second mounting slot 26 has two parts: a first part and a second part. The first part accommodates the first sub-component, and the second part accommodates the second sub-component.

[0065] Optionally, ventilation holes can be provided on both the upper cover 1 and the lower shell 2.
