Description

Technical Field

[0001] This utility model relates to the field of helmet technology, and in particular to a novel flip-up helmet lens structure. Background Technology

[0002] Helmets are essential tools for head protection and are indispensable in transportation, especially for motorcyclists and their passengers, as wearing a helmet ensures their safety. Full-face helmets should be used for competitive sports or high-speed driving. However, in lower latitude regions, such as southern towns in my country, long summers with high temperatures and humidity force motorcyclists to use half-face helmets. In winter, low temperatures and strong winds require full-face helmets for both safety and warmth, necessitating the storage of two types of helmets, which undoubtedly causes inconvenience. Therefore, a flip-up helmet has emerged on the market. This type of helmet adds a movable chin strap to the half-face helmet design, resembling a full-face helmet when closed and a half-face helmet when flipped up.

[0003] A search revealed that Chinese utility model patent CN202221915521.6 discloses a multi-functional combination helmet. Its features include a helmet body with detachable face shield, spectacle lens, and visor. Each of these components—face shield, spectacle lens, or visor—is individually mounted on the helmet body. A connector is located at the front of the helmet body, and rotating connectors are located on both sides. The face shield is used as a flip-up helmet, the spectacle lens as a visored helmet, and the visor as a non-visored helmet. The advantage is that the necessary accessories can be assembled according to actual usage needs, allowing one helmet to meet multiple usage scenarios, and the accessories are very easy to assemble and disassemble.

[0004] While the existing helmets meet basic usage requirements, their visors are connected to the helmet body via rotating connectors. The visor's rotation angle is adjusted solely by the interlocking action between a protrusion and a locking groove. When the visor encounters significant wind resistance, it tends to close automatically, affecting its performance. Furthermore, the structure is relatively complex, requiring tools for installation, making it inconvenient. Therefore, further improvements to the existing technology are necessary. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a new type of flip-up helmet lens structure to address the above-mentioned defects of the prior art. By adding a spring clip to hold the snap-fit ​​strip in place, the lens body is held in place, thus preventing the lens from closing easily and automatically. This design has good performance, a simple structure, and is easier to install.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
