Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle helmet lenses, in particular to a motorcycle helmet with a lens disassembly and assembly mechanism. Background Art

[0002] Motorcycle helmet lenses not only protect against the sun and fog, but also protect the eyes from dust, insects and other debris. Common materials include plexiglass, polycarbonate, glass and composite materials. After a period of use, motorcycle helmet lenses will be scratched and need to be disassembled, replaced or repaired.

[0003] For example, the announcement number CN205547528U discloses a detachable motorcycle helmet, including an outer shell having an empty space on the shell at a position of the user's face, a transparent cover movably installed on the empty space for the user to cover the face, an open structure below the empty space, non-through card slots on both sides of the transparent cover, a long transparent cover fitted with the outer surface of the transparent cover on the outer surface of the transparent cover, and card strips matching the non-through card slots on both sides of the long transparent cover. The motorcycle helmet is fixed with a shorter transparent cover on the helmet, and then a detachable long transparent cover is arranged on the transparent cover, so as to meet the needs of users in different usage scenarios. The main components of the product are common components, which greatly reduces the user's purchase cost compared to purchasing helmets of two structures. However, the motorcycle helmet still has other shortcomings in use. Since the motorcycle helmet is provided with a detachable long transparent cover on the transparent cover, only the long transparent cover can be disassembled, and the transparent cover fixed on the motorcycle helmet cannot be effectively disassembled. Therefore, there are still certain shortcomings when using the device. Utility Model Content
