Description

Technical Field

[0001] The invention belongs to the technical field of A42B3 / 00 helmets, and in particular relates to a helmet used by myopic people when wearing a mask. Background Art

[0002] The new mandatory national standard for electric bicycles, "Electric Bicycle Safety Technical Specifications", was implemented in April 2019, requiring that safety helmets must be worn when riding electric bicycles. On the other hand, with the increasing number of smog weather in my country, people's awareness of wearing masks to prevent smog when traveling has gradually increased. When myopic people wear masks, the hot air generated by the nose breathing can easily fog the lenses of myopic glasses, making it difficult to see the objects in front. This phenomenon is more obvious when wearing a helmet. How to solve the problem of myopic glasses lenses being fogged by breathing air when wearing a mask is a technical problem that must be solved when myopic people wear masks and ride electric bicycles. Summary of the invention

[0003] The purpose of the present invention is to provide a helmet for myopic people to use when wearing a mask, which can prevent fog from being generated on the lenses of myopic glasses due to oral and nasal breathing.

[0004] The technical solutions of the present invention are as follows:

[0005] A helmet used by myopic people when wearing a mask comprises a helmet shell and a helmet lens, wherein two gaps are opened in parallel on the helmet lens, and elastic seals corresponding to the gaps are arranged on the inner side of the helmet lens, and the elastic seals are clamped on the gaps to achieve sealing of the gaps, one end of the elastic seal is movably connected to the helmet lens, and the other end of the elastic seal is a free end.

[0006] The inventive concept of the present invention is that after the elastic seal is pulled out from the gap, it can be bent from bottom to top toward the face of the person. The free ends of the elastic seal exert pressure on the parts of the mask located on both sides of the user's nose, so that the upper part of the mask can be closely attached to the face of the person, reducing the breath of the nose from rushing out from the upper edge of the mask, and reducing the impact of the breath on the glasses. Since the mask is a layer of cloth, the mask has the function of assisting in fixing the free end of the elastic seal, so that the free end of the elastic seal is not easy to slide on the face of the person, thereby ensuring the compression effect of the elastic seal on the upper part of the mask. At the same time, after the elastic seal leaves the gap, the outside air enters from the gap during the user's riding process, and the air inside and outside exchange, which can further prevent the glasses from fogging. If the rider does not wear a mask, the elastic seal is stuck in the gap, which is no different from a normal helmet.

[0007] As an improvement, a steel sheet is provided inside the elastic seal strip, which can enhance the strength and deformation recovery performance of the elastic seal strip after deformation.

[0008] As a further improvement, the elastic seal includes a sheet and a strip for inserting into the gap, the strip being arranged along the length direction of the sheet and protruding from the outer surface of the sheet. The free end of the elastic seal is twisted so that the outer side of the sheet and the strip are in contact with the human face, so that the elastic seal is twisted and stretched between the helmet lens and the human face, so that the elastic seal can generate lateral tension, causing the mask to be laterally attached to the human face, further preventing the breath from rushing from the upper edge of the mask to the lens of the myopic glasses.

[0009] As a further improvement, the two gaps on the helmet lens are arranged vertically and spaced 3-6 cm apart. The distance between the two gaps is determined according to the structure of the human face.

[0010] In summary, the beneficial effects of the present invention are: simple structure, novel design, and easy use. When a rider wears a mask, it can prevent the breath from fogging the lenses of the myopic glasses, and it can also enhance the stability of the helmet on the rider's head, thereby improving the safety and health of the rider.

[0015] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0016] Example 1

[0017] like Figure 1 As shown, the helmet used by myopic people wearing masks according to the present invention comprises a helmet shell 1 and a helmet lens 2. The helmet shell 1 and the helmet lens 2 refer to the common structures in the prior art. The present invention only improves the helmet lens 2.

[0018] like Figure 1 , Figure 2As shown, two gaps 3 are arranged side by side on the helmet lens 2, and the two gaps 3 on the helmet lens 2 are arranged vertically, so that air can circulate inside and outside the helmet. The width of the gap 3 is preferably 0.1-0.2 cm. If it is too wide, the air flow inside and outside the helmet will be too large, and the face of the person will be easily cold when the temperature is low. Since the mask has a warming effect, when the temperature is low, the mask can resist some cold air entering the helmet through the gap 3.

[0019] The apex of the gap 3 is located in the middle of the helmet lens 2 so as not to affect the rider's vision.

[0020] An elastic seal 4 corresponding to the gap 3 is arranged on the inner side of the helmet lens 2. The elastic seal 4 is stuck on the gap 3 to seal the gap 3. One end of the elastic seal 4 is movably connected to the helmet lens 2, and the other end of the elastic seal 4 is a free end.

[0021] like Figure 3 As shown, a steel sheet 41 is provided inside the elastic seal 4 to ensure the elasticity of the elastic seal 4. The outside of the elastic seal 4 is wrapped with silicone to ensure comfort. The elastic seal 4 includes a sheet 42 and a strip 43 for inserting into the gap 3. The top of the sheet 42 is hinged to the helmet lens 2, and the sheet 42 can rotate at a certain angle around the hinge point. The strip 43 is arranged along the length direction of the sheet 42 and protrudes from the outer surface of the sheet 42. The strip 43 is used to insert into the gap 3.

[0022] The outer wall of a general mask is not smooth, and the free end of the elastic seal 4 is against the mask, and the free end is not easy to slide. In addition, due to the elastic force of the elastic seal 4, the elastic seal 4 is not easy to move after being against the mask.

[0023] According to the volume size of the helmet, the two gaps 3 can be selected within 3-6 centimetres. Because the sheet body 42 can rotate at a certain angle around the hinge point, the elastic seal 4 has a stronger adaptability for the size of the face.

[0024] Since the elastic seal 4 has a certain deformation ability, before the elastic seal 4 is pressed against the mask, the free end of the elastic seal 4 is twisted toward the nose. Figure 3 The free end of the elastic seal 4 is twisted and abuts against the mask, and the outer sides of the strip 43 and the sheet 42 are pressed against the face of the person, and the torsion of the elastic seal 4 stretches the mask laterally toward both sides of the nose, which is conducive to the upper edge of the mask being close to the face of the rider, and can further prevent the breath from leaking upward from the upper edge of the mask.
