[0030] Reference Figures 1-5 In some specific embodiments, a helmet with a quick-release lens structure includes a shell 1 and a lens 3, with mounting seats 2 provided on both sides of the shell 1, and connecting ends 25 provided at both ends of the lens 3. The connecting ends 25 at both ends of the lens 3 are connected to the mounting seats 2 on both sides of the shell 1, and a first connecting groove 8 and a movable groove 26 are provided on one side of the mounting seat 2. The first connecting groove 8 is connected to the movable groove 26, and a limiting slot 16 is provided on one side of the movable slot 26. A rotating column 4 is provided on one side of the connecting end 25, and a first limiting protrusion 5 is provided on one side of the rotating column 4. The rotating column 4 is rotatably connected to the movable groove 26 so that the first limiting protrusion 5 is plugged into the limiting slot 16. A movable plug-in plate 20 is slidably connected to the inside of the first connecting groove 8, and one end of the movable plug-in plate 20 is provided with a plug-in end 21, which faces the movable groove 26, and a limiting notch 22 is provided on one side of the plug-in end 21. A second limiting protrusion 7 is provided on the other side of the rotating column 4, and the second limiting protrusion 7 is plugged into the limiting notch 22.

[0031] Through the above technical solution, when the lens 3 needs to be removed, the user only needs to slide the movable plug plate 20 so that the plug-in end 21 of the movable plug plate 20 is disengaged from the movable groove 26, the second limiting protrusion 7 is disengaged from the plugging of the limiting notch 22, the first limiting protrusion 5 is disengaged from the plugging of the limiting slot 16, and the rotating column 4 is disengaged from the movable groove 26, thereby facilitating the removal of the damaged lens 3; when a new lens 3 is installed, the movable plug plate 20 is slid so that the plug-in end 21 of the movable plug plate 20 is away from the movable groove 26, the rotating column 4 is inserted into the movable groove 26, the first limiting protrusion 5 is plugged into the limiting slot 16, and then the movable plug plate 20 is slid so that the plug-in end 21 of the movable plug plate 20 is inserted into the movable groove 26, and the second limiting protrusion 7 is plugged into the limiting notch 22, thereby limiting the position of the lens 3, without the need for additional tools, and simplifying the installation method of the lens 3.

[0032] Compared with the traditional articulated connection, the quick-release structure of the present application has obvious advantages. The traditional articulated connection usually requires the use of tools to disassemble the lens 3, which is complicated and time-consuming. The design of the present application allows the user to complete the disassembly and assembly of the lens 3 through simple manual operation without using any tools, greatly shortening the time for replacing the lens 3 from several minutes to a few seconds, thereby improving the user's response efficiency in daily use and emergency situations.

[0033] In addition, under the dual limiting mechanism of the first limiting protrusion 5 being plugged into the limiting slot 16 and the second limiting protrusion 7 being plugged into the limiting notch 22, the stability of the lens 3 under various riding conditions is ensured. Even when driving at high speed or on bumpy roads, the lens 3 can remain stable and will not accidentally fall off or shake, thereby improving riding safety.

[0034] Reference Figures 2-4, in some specific embodiments, a first extension groove 17 is formed on one side of the movable groove 26. The first extension groove 17 communicates with the limit slot 16, and the first limit projection 5 is slidably engaged with the first extension groove 17.

[0035] Referring to Figures 2-4 , in some specific embodiments, a second extension groove 18 is formed on the other side of the movable groove 26. The second extension groove 18 communicates with the limit notch 22, and the second limit projection 7 is slidably engaged with the second extension groove 18.

[0036] Through the above technical solution, when the position of the lens 3 needs to be adjusted, the user can gently rotate the lens 3, so that the first limit projection 5 slides in the first extension groove 17, and the second limit projection 7 slides in the second extension groove 18. Since the first extension groove 17 is connected to the limit slot 16, and the second extension groove 18 communicates with the limit notch 22, the first limit projection 5 and the second limit projection 7 can move within a relatively large range, thereby realizing multi-angle adjustment of the position of the lens 3.

[0037] Referring to Figures 2-5 , in some specific embodiments, a second connection groove 9 is formed on one side of the mounting seat 2. First guiding chutes 11 are formed on both sides of the second connection groove 9. The other end of the movable insertion plate 20 is provided with a movable plate 19. Guiding surfaces 29 are provided on both sides of the movable plate 19. The guiding surfaces 29 on both sides of the movable plate 19 are respectively slidably engaged with the first guiding chutes 11 on both sides of the second connection groove 9.

[0038] Through the above technical solution, the second connection groove 9 provides a moving space for the movable insertion plate 20. The guiding surfaces 29 on the movable plate 19 are slidably engaged with the first guiding chutes 11, ensuring the stability and accuracy of the movable insertion plate 20 during the moving process. This structural design not only enhances the mounting stability of the movable insertion plate 20, but also improves its guiding property, enabling the movable insertion plate 20 to slide more smoothly on the mounting seat 2.

[0039] The contact surfaces of the guiding surfaces 29 and the first guiding chutes 11 can adopt materials with a low coefficient of friction, such as polytetrafluoroethylene (PTFE) coating, to further reduce friction and extend the service life of the components.

[0040] Referring to Figures 2-5 , in some specific embodiments, a reset groove 10 is formed on one side of the mounting seat 2. One end of the movable plate 19 is provided with an elastic support leg 23. The elastic support leg 23 is slidably connected to the reset groove 10. One end of the elastic support leg 23 is provided with a deformation end 30. The deformation end 30 has elasticity. The deformation end 30 and the movable plate 19 are separated to form a movable interval 24.

[0041] Through the above technical solution, when an external force acts on the movable plate 19, such as manually pushing the movable plate 19, the deformable end 30 will be compressed and deformed, so that the deformable end 30 enters the reset groove 10. When the external force disappears, the elastic deformable end 30 will automatically restore to its original shape, thereby driving the movable plate 19 back to its initial position, so that the second limiting protrusion 7 can be plugged into the limiting notch 22. This elastic reset mechanism simplifies the disassembly and assembly operation of the lens 3 and improves the convenience of using the helmet.

[0042] Reference Figure 2 In some specific embodiments, a toggle slot 28 is provided on one side of the movable plate 19 .

[0043] With the above technical solution, by providing the toggle slot 28 on the movable plate 19 , the user can push and pull the movable plate 19 more easily, thereby controlling the movement of the movable plug plate 20 .

[0044] In addition, the toggle groove 28 can adopt a variety of shapes and sizes to adapt to different user needs and finger sizes; for example, it can be designed as a semicircular, rectangular or elliptical groove, with a depth between 3mm and 10mm and a width between 10mm and 30mm; such a design can ensure that most users can operate it easily.

[0045] Reference Figures 2-3 In some specific embodiments, a second guide slot 12 is provided on one side of the mounting seat 2 , and a guide column 6 is provided on one side of the connecting end 25 , and the guide column 6 is slidably engaged with the second guide slot 12 .

[0046] Through the above technical solution, by pushing the lens 3, the guide post 6 slides in the second guide slot 12, thereby increasing the stability of the lens 3 during movement.

[0047] Reference Figures 1-3 In some specific embodiments, a movable spring block 13 is provided on one side of the second guide slot 12 . The movable spring block 13 is elastic, and one side of the movable spring block 13 contacts the guide column 6 .

[0048] Through the above technical solution, when the lens 3 rotates, one side of the movable spring block 13 contacts the guide column 6, which can apply a certain pressure to the guide column 6, so that the movement of the guide column 6 in the second guide groove 12 is subject to a certain resistance, thereby achieving precise control and fixation of the position of the lens 3.

[0049] In addition, the contact surface between the movable spring block 13 and the guide column 6 can be designed into various shapes, such as a flat surface, a curved surface, or a surface with tiny protrusions, so as to increase friction and improve the accuracy of adjustment.

[0050] Reference Figures 1-3, in some specific embodiments, a plurality of limiting bumps 14 are provided on one side of the movable block 13, and an adjusting interval 15 is formed between adjacent limiting bumps 14, and the guide post 6 is inserted into any one of the adjusting intervals 15.

[0051] Through the above technical solution, the user can gently push or pull the lens 3 to move the guide post 6 between different adjusting intervals 15. When the guide post 6 enters a certain adjusting interval 15, the movable block 13 will exert an appropriate pressure on the guide post 6 due to its elasticity, thereby fixing the lens 3 at the required position. This design not only allows the user to adjust the position of the lens 3 according to personal needs, but also maintains the stability of the lens 3 during riding.

[0052] In addition, the movable block 13 can be made of an elastic material such as nylon or elastic plastic, which can provide an appropriate buffering effect while ensuring the adjustment function. The guide post 6 can be made of a wear-resistant material such as stainless steel or high-strength engineering plastic to improve its service life.

[0053] Referring to Figure 1 , in some specific embodiments, the lens 3 is made of a transparent material.

[0054] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
