The clamping block is formed on the mask 2, and the clamping portion is made of a material with memory deformation property, such as hard rubber, to avoid mechanical fracture.

[0067] Embodiment 3:

[0068] The helmet with stable mask fastening provided in the embodiment further has the following technical features in addition to the technical solutions in the above embodiments.

[0069] The shell 1 and the inner liner are provided with a plurality of air permeation channels communicating with the outside.

[0070] The air permeation channel of the helmet improves the wearing experience through the following core functions:

[0071] Heat dissipation: The air flow entering through the front air holes forms a circulation inside the helmet, taking away the heat of the head and relieving the stuffy feeling caused by long-time wearing.

[0072] Keep dry: Air flow accelerates evaporation of sweat, reduces head moisture, and maintains freshness during cycling.

[0073] Reduce wind resistance: Optimized air duct design can guide air flow, reduce wind resistance during high-speed cycling, and enhance the stability of the helmet.

[0074] Anti-fog and dehumidification: Part of the air inlet is designed to adjust the air flow to prevent the lens from fogging due to temperature difference, and to improve the clarity of the line of sight.

[0075] Auxiliary breathing: Special air vents deliver air at a fixed rate, and are equipped with filter screens to block particulate matter, ensuring safe breathing.

[0076] In addition, high-end helmets are designed with dense air holes and insect screens to further optimize ventilation efficiency and practicality.

[0077] Embodiment 4:

[0078] The helmet with stable mask fastening provided in the embodiment further has the following technical features in addition to the technical solutions in the above embodiments.

[0079] A valve door is arranged on the shell 1 and installed on the opening of the air permeation channel.

[0080] Function:

[0081] Adjust the ventilation efficiency

[0082] By manually or automatically adjusting the opening and closing degree of the valve door, the size of the air flow entering the helmet can be accurately controlled, and the ventilation intensity can be freely switched.

[0083] Adapt to environmental changes

[0084] Low temperature / low speed scenario: closing the valve can reduce the direct blowing of cold air on the head, avoiding rapid loss of body temperature;

[0085] High temperature / high speed scenario: opening the valve can accelerate heat dissipation, while optimizing the air duct design to reduce wind resistance and enhance riding stability.

[0086] Dust and water-proof design

[0087] Some valves use sealing structure or filter screen to block rain, dust and other foreign matter from entering the inside of the helmet in closed state, keeping the inside dry and clean.

[0088] Auxiliary safety function

[0089] Some valves are linked with the anti-fog system of the lens, balancing the temperature difference between inside and outside by adjusting the airflow direction to prevent the lens from fogging and affecting the vision. In addition, the safety valve design can prevent the helmet from deforming or being uncomfortable to wear due to excessive air pressure.

[0090] Such valves realize dynamic adaptation of the ventilation system through physical opening and closing mechanism (such as rotation, push-pull) or intelligent sensing control, taking into account comfort and safety.

[0091] Example 5:

[0092] This embodiment provides a helmet with stable mask fastening, which, in addition to the technical solutions of the above-mentioned embodiments, has the following technical features.

[0093] Breathable channels are respectively arranged at the mouth, top of the head and back of the head of the helmet.

[0094] Top of the head and back of the head: air flow enters from the front (such as the mouth or forehead) and flows naturally along the surface of the head, forming a complete cycle through the exhaust holes at the top of the head and the back of the head, efficiently taking away heat and moisture.

[0095] Mouth area: the ventilation port near the mouth and nose can be adjusted to the breathing rhythm, directly introducing fresh air, reducing the retention of exhaled carbon dioxide and improving the comfort of breathing.

[0096] Top of the head: the head sweat glands are concentrated, and heat is easy to accumulate. The top air hole can quickly guide out the hot and humid air flow to prevent stuffiness.

[0097] Back of the head: the back exhaust hole cooperates with the natural wind direction during riding to accelerate air flow discharge, avoid vortex interference and maintain stable ventilation.

[0098] Adapt to different environmental conditions

[0099] Mouth adjustable design: some helmets are equipped with switchable valves at the mouth, which can adjust the air intake according to temperature or wind speed (such as reducing cold wind direct blowing in cold weather and enhancing heat dissipation in high temperature weather).

[0100] Back anti-foreign design: the rear exhaust hole is usually equipped with a dust screen or a guide vane to block rain, flying insects, etc. from entering, ensuring the internal cleanliness.

[0101] The head and back areas have high structural strength, and the air holes do not weaken the overall protective performance of the helmet;

[0102] The mouth ventilation avoids blocking the line of sight or interfering with the lens function, while reducing the wind noise impact during high-speed riding.

[0103] The combination of air holes in these three positions can achieve a closed-loop ventilation system of "low wind resistance intake → high-efficiency heat dissipation → rapid moisture removal", balancing comfort, safety, and environmental adaptability.

[0104] When the mask 2 is opened, the side of the hinged rod of the mask 2 relative to the clamping rod 6 is provided with an anti-falling part, and the anti-falling part is provided with a first inclined surface, and the edge of the hinge hole formed by the clamping rod 6 is provided with a second inclined surface.

[0105] The anti-falling part has the same curvature as the edge of the hinge hole formed by the clamping rod 6, and the anti-falling part is formed by extending outwardly from the end of the hinged rod, when the mask 2 needs to be disassembled, the clamping rod 6 is separated from the fixed clamp body, so that the anti-falling part can be removed, realizing disassembly, the first inclined surface and the second inclined surface can be set without manually separating the clamping rod 6 from the fixed clamp body, and the anti-falling part can be installed in the hinge hole by the downward pressing mode.

[0106] The end of the stop rod 8 of the mask 2 is provided with a hooking part hooked on the back of the first main body 3.

[0107] The hooking part prevents the stop rod 8 from axially sliding in the groove, and prevents the cooperation failure of the stop rod 8 and the groove due to axial sliding.

[0108] It should be noted that the hooking part and the anti-falling part form a double clamping structure, which can increase the stability of the mask 2 installation structure.

[0109] The embodiments of the present application are described above in combination with the drawings, and in the case of no conflict, the embodiments and the features in the embodiments can be combined with each other, the present application is not limited to the above-mentioned specific embodiments, the above-mentioned specific embodiments are only illustrative, not limiting, and those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the protection scope of the claims.
