For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0042] The following is combined with Figure 1-7 The technical solution of the utility model is further illustrated through specific implementation methods.

[0043] A preferred embodiment in the present application is a snap-on dual-density foam helmet, which includes a foamed polypropylene (EPP) shell 1, a foamed polystyrene (EPS) shell 2, an aramid KEVLAR fiberboard 3 and a snap-on structure 4. An opening area 11 is provided in the middle area of ​​the EPP shell 1, the EPS shell 2 is installed in the opening area 11, and the KEVLAR fiberboard 3 is attached to the top of the EPS shell 2; a snap-on structure 4 is provided between the EPP shell 1 and the EPS shell 2, and the EPS shell 2 is installed in the opening area 11 based on the snap-on structure 4.

[0044] Specifically, EPP (Expanded Polypropylene) is expanded polypropylene, EPS (Expandab l ePo l ystyrene) is expanded polystyrene, the EPP shell 1 has high strength, high toughness, good cushioning performance and environmental protection, the EPS shell 2 has the advantage of light weight, can reduce the weight of the foam helmet, reduce the wearer's weight, and avoid excessive consumption of the wearer's physical strength, the KEVLAR fiberboard 3 is aromatic polyamide fiber (abbreviated as "aramid"), the KEVLAR fiberboard 3 is Kevlar fiberboard, which has high strength and impact resistance. Fitting the KEVLAR fiberboard 3 to the top of the EPS shell 2 can effectively absorb and disperse impact force, and can significantly improve the protective performance of the helmet, thereby protecting the wearer's head from injury. A snap structure 4 is provided between the EPP shell 1 and the EPS shell 2, and the installation of the EPP shell 1 and the EPS shell 2 is achieved through the snap structure 4. This technical solution solves the problems of dual-density combined foam helmets such as glue bonding being not environmentally friendly, easy to aging and falling off, and complex structure.

[0045] In an optional embodiment, the buckle structure 4 includes: a plurality of first connecting embedded buckles 41, a plurality of second connecting embedded buckles 42 and a plurality of third connecting embedded buckles 43;

[0046] The EPP housing 1 is provided with a plurality of first connecting embedded buckles 41;

[0047] The EPS shell 2 is provided with a plurality of third connecting embedded buckles 43;

[0048] Each of the first connecting embedded buckles 41 and the corresponding third connecting embedded buckles 43 are vertically arranged opposite each other;

[0049] Each of the first connecting embedded buckles 41 is installed on a corresponding one of the third connecting embedded buckles 43 , and the second connecting embedded buckle 42 is sleeved on the junction of the first connecting embedded buckle 41 and the third connecting embedded buckle 43 .

[0050] Specifically, the first connecting embedded buckle 41 and the third connecting embedded buckle 43 are installed vertically opposite each other by snap-fitting. This design makes the connection between the EPP shell 1 and the EPS shell 2 more secure and not easy to loosen or fall off due to external force; and the second connecting embedded buckle 42 is sleeved on the junction of the first connecting embedded buckle 41 and the third connecting embedded buckle 43, thereby further enhancing the overall structural stability of the foam helmet, ensuring that the foam helmet can remain intact when impacted, and effectively protecting the wearer's head.

[0051] In an optional embodiment, the first connecting embedded buckle 41 includes a first body 411 and a first base 412. The first body 411 has a protrusion 4111. The first body 411 is mounted on the upper surface of the first base 412. The first base 412 is mounted on the edge of the opening area 11.

[0052] The second connecting embedded buckle 42 includes a second body 421, and the second body 421 is provided with a through hole 4211;

[0053] The third connecting embedded buckle 43 includes a third body 431 and a third base 432. The third body 431 is provided with a barb 4311. The third body 431 is mounted on the lower surface of the third base 432. The third base 432 is mounted on the EPS shell 2.

[0054] When each of the first connecting embedded buckles 41 is snap-fitted and installed on a corresponding one of the second connecting embedded buckles 42, the protrusion 4111 clamps the through hole 4211; when each of the third connecting embedded buckles 43 is snap-fitted and installed on a corresponding one of the first connecting embedded buckles 41, the protrusion 4111 clamps the barb 4311.

[0055] Specifically, the protrusion 4111 is clamped with the through hole 4211, so that the first connection embedded buckle 41 and the second connection embedded buckle 42 form a firm mechanical connection; the through hole 4211 is clamped with the barb 4311, so that the second connection embedded buckle 42 and the third connection embedded buckle 43 form a firm mechanical connection. This assembly relationship stabilizes the connection between the EPP shell 1 and the EPS shell 2. In addition, the snap-on connection does not require additional screws, nuts or other fasteners, which simplifies the assembly process of the helmet, improves production efficiency, and also makes it convenient for users to disassemble and repair the helmet when needed.

[0056] In an optional embodiment, the EPP housing 1 is provided with a plurality of first mounting openings 12 , each of the first mounting openings 12 is evenly spaced and arranged at an edge of the opening area 11 , and the first base 412 is installed at the first mounting opening 12 .

[0057] Specifically, the setting of the first mounting port 12 enables the first base 412 to be firmly mounted on the EPP shell 1, thereby enhancing the overall structural stability of the foam helmet, and the evenly spaced setting of the first mounting ports 12 can ensure that the first base 412 can evenly distribute external force after installation, thereby improving the impact resistance of the foam helmet.

[0058] In an optional embodiment, the EPS shell 2 is provided with a plurality of second mounting ports 21 , each of the second mounting ports 21 is arranged vertically opposite to a corresponding first mounting port 12 , and the third base 432 is installed at the second mounting port 21 .

[0059] Specifically, by arranging the second mounting opening 21 and the first mounting opening 12 in a vertically opposed relationship, and installing the third base 432 on the second mounting opening 21, a tight connection between the EPP shell 1 and the EPS shell 2 can be ensured. This design not only enhances the structural integration of the foam helmet, but also improves its impact resistance and overall stability. Furthermore, when a part of the foam helmet needs to be repaired or replaced, it can be done by removing the component on the corresponding mounting opening, reducing maintenance costs and time.

[0060] In an optional embodiment, the EPS shell 2 presents an elliptical structure that is wide in the front and narrow in the back in a vertical projection, and the EPS shell 2 presents an arc-shaped structure that is short in the front and high in the back in a horizontal projection.

[0061] Specifically, the elliptical structure of the EPS shell 2, which is wide in front and narrow in the back, ensures that the front of the foam helmet has enough width to cover the wearer's forehead area. At the same time, the back of the foam helmet gradually narrows, naturally fitting the wearer's head contour; the arc-shaped structure of the EPS shell 2, which is short in front and high in the back, conforms to the natural curve of the human head, and realizes a smooth transition from the front to the back of the foam helmet, ensuring the wearer's comfort and stability when wearing it. Moreover, since the EPS shell 2 has the advantage of being light in weight, it effectively reduces the oppressive feeling of the foam helmet on the wearer's head, thereby improving the wearing comfort.

[0062] In an optional embodiment, the foam helmet further includes a forehead pad 51 and a top pad 52;

[0063] The forehead pad 51 is installed at the front end of the EPP shell 1 , and the top of the head pad 52 is installed inside the EPP shell 1 .

[0064] Specifically, the forehead pad 51 can fit the forehead area of ​​the wearer, reduce the pressure of the foam helmet on the wearer's head, and improve the wearing comfort. The top of the head pad 52 is located inside the foam helmet, which can further disperse the pressure of the foam helmet on the wearer's head and reduce fatigue when worn for a long time. The forehead pad 51 and the top of the head pad 52 are usually made of soft and elastic materials, such as EPS foam, memory foam, etc. These materials can provide additional cushioning in the event of an accident and further protect the wearer's head safety.

[0065] In an optional embodiment, the foam helmet includes a first headlight mounting buckle 61, a second headlight mounting buckle 62 and a headlight 63, and the EPP shell 1 is provided with a headlight mounting slot 13;

[0066] The second headlight mounting buckle 62 is snap-fitted into the headlight mounting groove 13;

[0067] The first headlight mounting buckle 61 is snap-fitted to the second headlight mounting buckle 62;

[0068] The headlight 63 is mounted on the first headlight mounting buckle 61 .

[0069] Specifically, the headlight 63 is installed on the EPP housing 1 through the first headlight mounting buckle 61 and the second headlight mounting buckle 62, which is simpler and faster than traditional screw fixing or glue bonding, which means that if the headlight 63 is damaged or needs to be upgraded, the user can easily replace it.

[0070] In an optional embodiment, the first headlight mounting buckle 61 is provided with a male buckle 611 , one end of the second headlight mounting buckle 62 is provided with an arc-shaped mounting portion 621 , and the other end of the second headlight mounting buckle 62 is provided with a female buckle 622 ;

[0071] The arc-shaped mounting portion 621 is snap-fitted to the headlight mounting groove 13 , and the male buckle 611 is snap-fitted to the female buckle 622 .

[0072] Specifically, through the snap connection mode of the male buckle 611 and the female buckle 622, the installation and disassembly of the headlight 63 becomes very simple and quick, and the male buckle 611 and the female buckle 622 ensure the stability of the headlight 63 after installation, reducing the risk of loosening or falling off due to vibration or impact, and the arc-shaped mounting portion 621 can better fit the headlight mounting groove 13 for installation, reducing the installation gap between the second headlight mounting buckle 62 and the EPP shell 1.

[0073] In an optional embodiment, the EPP housing 1 further includes a rear light mounting hole 14, and the rear light mounting hole 14 is provided at the rear of the EPP housing 1;

[0074] The foam helmet further includes a rear light belt clip hook 71 and a rear light belt 72 . The rear light belt 72 passes through the rear light belt clip hook 71 and is installed in the rear light installation hole 14 . The rear light belt clip hook 71 is clamped and installed at the rear of the EPP shell 1 .

[0075] Specifically, the rear light strip 72 can alert people behind, thereby effectively reducing the probability of accidents such as collisions due to insufficient light brightness. The rear light strip clip 71 can make the rear light strip 72 easily pass through and clamped at the rear of the EPP shell 1, which not only simplifies the installation process, but also facilitates the wearer's disassembly and replacement in daily use.
