[0002] With the continuous development of fields such as industrial safety protection, fire rescue, military operations and extreme sports, high-performance safety helmets, as key personal protective equipment, are becoming increasingly important. In various complex environments, the inner lens of the helmet is crucial for ensuring the user's visual clarity, protective effect and situational awareness.

[0003] However, existing helmets are not convenient to adjust and control the opening and closing of the visor, and it is difficult to conveniently adjust the visor state according to actual needs. This reduces the convenience of using the device and makes it difficult for users to focus on sports that require a helmet, such as cycling, thus affecting the user's safety. Utility Model Content

[0004] The purpose of this utility model is to provide a helmet lens control structure. By setting up a control unit, it solves the problem that existing helmets are not convenient to adjust the opening and closing of the lens during use, and it is difficult to conveniently adjust the lens state according to actual needs, thereby reducing the convenience of using the device, making it difficult for users to focus on sports that require a helmet, such as cycling, and thus affecting the user's safety.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a helmet lens control structure, including a helmet shell and further comprising: a lens section disposed on the helmet shell; two control sections, which are mirror images of each other mounted on the helmet shell; and two locking sections, which are mirror images of each other disposed inside the helmet shell. The control section includes a control component mounted on the helmet shell; and a support component disposed on the helmet shell. The control component includes a first rotating shaft disposed inside the helmet shell, with a gear fixedly connected to its outer wall. A second rotating shaft is disposed inside the helmet shell, with a half-gear fixedly connected to its outer wall. A transmission component is disposed on the second rotating shaft. The gear and the half-gear mesh with each other. The first rotating shaft, the gear, the second rotating shaft, the half-gear, and the transmission component constitute the control component, which, in conjunction with the support component, provides a transmission basis for lens adjustment. The support component ensures stable installation and rotation of all components, jointly achieving lens opening and closing control.

[0007] Furthermore, the lens section includes a lens disposed on the helmet shell; the lens is made of transparent material, and as the core component of the lens section, the lens is made of transparent material and disposed on the helmet shell, and is a key component for achieving clear visual observation.

[0008] Furthermore, the locking part includes an elastic component disposed on the half gear; and a snap-fit ​​component disposed inside the helmet shell. The elastic component and the snap-fit ​​component are components of the locking part, respectively disposed inside the half gear and the helmet shell, providing structural support for locking the lens position.

[0009] Furthermore, the support assembly includes a support block fixedly connected to the helmet shell, the rear side of the first rotating shaft is rotatably connected to the support block, the second rotating shaft rotatably passes through the support block, and a bracket is fixedly connected to the outer wall of the first rotating shaft, with the outer wall of the bracket fixedly connected to the lens.

[0010] Furthermore, the elastic component includes a mounting groove formed on the half gear, and two spring telescopic rods are fixedly connected to the inner wall of the mounting groove. The two spring telescopic rods are mirror images of each other. The mounting groove provides mounting space for the spring telescopic rods. The two mirrored spring telescopic rods, as parts of the elastic component, provide elastic driving force for the locking part.

[0011] Furthermore, the buckle assembly includes a buckle block fixedly connected to the side of the two spring telescopic rods away from the pivot. A limit pin is fixedly connected to the front side of the support block. The outer wall of the limit pin contacts the inner wall of the buckle block. The buckle block is connected to the spring telescopic rods. The limit pin is fixed on the support block. As parts of the buckle assembly, the two lock the position of the lens through contact and cooperation.

[0012] Furthermore, the transmission component includes a handle fixedly connected to the outer wall of the second rotating shaft; the front side of the handle contacts the support block. The handle, as a transmission component, is fixed on the second rotating shaft and contacts the support block, and is a key component that facilitates user operation to drive the lens to rotate.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting up a control unit, the visor inside the helmet can be adjusted. Through the coordinated action of the control components and support components, and with the meshing transmission of gears and half gears, the external operation is converted into the rotation of the visor, thereby realizing the opening and closing adjustment of the visor. At the same time, the support components provide a stable mounting and support base for each rotating part, ensuring the smoothness and stability of the entire adjustment process. This allows users to easily adjust the visor state according to actual needs, while allowing users to focus more on sports that require a helmet, such as cycling, thereby ensuring the safety of the user.

[0015] 2. The locking mechanism is designed to secure the lens after it has been adjusted to the desired position. Through the cooperation of the elastic component and the buckle component, the buckle component engages with the relevant parts when the lens reaches the appropriate position. The elastic force of the elastic component maintains the locked state, effectively preventing the lens from rotating unnecessarily due to accidental contact or vibration during use. This ensures the stability of the lens position, protects the user's vision from interference, and enhances the safety and reliability of helmet use.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 As shown, this utility model is a helmet internal lens control structure, including a helmet shell 111, and further including: a lens part 1, which is disposed on the helmet shell 111; a control part 2, two of which are mounted on the helmet shell 111 in a mirror image; and a locking part 3, two of which are disposed inside the helmet shell 111 in a mirror image. The lens part 1 includes a lens 112 disposed on the helmet shell 111; the lens 112 is made of transparent material.

[0027] The control unit 2 includes a control component 21 mounted on the helmet shell 111; and a support component 22 mounted on the helmet shell 111. The control component 21 includes a first rotating shaft 211 disposed inside the helmet shell 111, with a gear 212 fixedly connected to its outer wall. A second rotating shaft 213 is disposed inside the helmet shell 111, with a half gear 214 fixedly connected to its outer wall. A transmission component is disposed on the second rotating shaft 213. The gear 212 meshes with the half gear 214. The support component 22 includes components fixedly connected to the helmet shell 111. The support block 221 on 11 has a rotating shaft 211 rotatably connected to the rear side of the support block 221. A rotating shaft 213 rotatably passes through the support block 221. A bracket 222 is fixedly connected to the outer wall of the rotating shaft 211. The outer wall of the bracket 222 is fixedly connected to the lens 112. The transmission component includes a handle 215 fixedly connected to the outer wall of the rotating shaft 213. The front side of the handle 215 contacts the support block 221. By setting the control unit 2, the opening and closing adjustment of the lens is realized, which allows the user to conveniently adjust the lens state according to actual needs and improves the convenience of use.

[0028] The locking part 3 includes an elastic component 31, which is disposed on the half gear 214; and a buckle component 32, which is disposed inside the helmet shell 111. The elastic component 31 includes a mounting groove 311 formed on the half gear 214, and two spring telescopic rods 312 are fixedly connected to the inner wall of the mounting groove 311. The two spring telescopic rods 312 are mirror images of each other. The buckle component 32 includes a locking block 321 fixedly connected to the side of the two spring telescopic rods 312 away from the second pivot 213. A limit pin 322 is fixedly connected to the front side of the support block 221. The outer wall of the limit pin 322 contacts the inner wall of the locking block 321. By setting the locking part 3, unnecessary rotation of the lens due to accidental contact or vibration during use is prevented, thereby ensuring that the user's vision is not interfered with.

[0029] A specific application of this embodiment is as follows: In use, rotating the handle 215 causes the handle 215 to drive the half gear 214 to rotate via the second rotating shaft 213. The half gear 214 then drives the first rotating shaft 211 to rotate via the gear 212. Consequently, the first rotating shaft 211 drives the lens 112 to rotate via the bracket 222. The lens 112 then drives the control unit 2 on the other side to operate synchronously, thereby opening the lens 112. During this process, when the half gear 214 rotates, the locking block 321 moves in a circular motion around the second rotating shaft 213. After being squeezed by the limiting pin 322, it approaches the second rotating shaft 213, causing the two spring telescopic rods 312 to be compressed until the limiting pin 322 slides into another semi-circular groove on the locking block 321. The spring telescopic rod 312 rebounds, causing the locking block 321 to reset, so that the limiting pin 322 locks the locking block 321 to prevent the half gear 214 from rotating, thereby preventing the lens 112 from rotating accidentally. When closing the lens 112, reversing the handle 215 will close the lens 112 through a similar process described above.
