Detailed Implementation

[0024] 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.

[0025] Please see Figures 1-6 This utility model provides a technical solution:

[0026] A helmet with a sun visor switching function includes an outer helmet 1. The outer helmet 1 has a switching mechanism 2 inside for switching between helmet and sun visor states. The switching mechanism 2 includes:

[0027] The sliding unit 21 is located inside the outer helmet 1 and includes an inner helmet 211. The top of the inner helmet 211 is provided with an arc-shaped sliding groove 212 and an arc-shaped limiting groove 213. A sliding column 214 is slidably installed inside the arc-shaped sliding groove 212, and a limiting block 215 is fixedly installed above the sliding column 214. The limiting block 215 is located inside the arc-shaped limiting groove 213 and slides accordingly. An arc-shaped fixing rod 216 is fixedly installed at the top of the limiting block 215, and a sun visor 217 is fixedly installed on one side of the arc-shaped fixing rod 216. The arc-shaped fixing rod 216 moves by sliding the sliding column 214 and the limiting block 215 inside the arc-shaped sliding groove 212 and the arc-shaped limiting groove 213, so that the sun visor 217 moves out of the outer helmet 1, realizing the switching between the helmet and sun visor states.

[0028] The drive unit 22 is disposed on the side of the inner helmet 211 and is used to drive the movement of the arc-shaped fixing rod 216.

[0029] In this embodiment, a fixing ring seat 218 is fixedly installed at the bottom of the inner helmet 211, and an arc-shaped through groove 219 is provided on the front side of the fixing ring seat 218. The sunshade 217 slides inside the arc-shaped through groove 219, and the inner corners of the arc-shaped through groove 219 are all rounded.

[0030] The arc-shaped through groove 219 on the front side of the fixed ring seat 218 provides a precise guide track for the telescopic sliding of the sunshade 217. Combined with the rounded corner structure, it significantly reduces the sliding friction resistance and ensures a smooth and unobstructed process for switching the sunshade function.

[0031] In this embodiment, several iron wires 2110 are fixedly installed inside the sunshade 217 to enable the sunshade 217 to bend.

[0032] An iron wire 2110 is embedded inside the sunshade 217, giving the sunshade flexible and adjustable characteristics. Users can manually bend the sunshade to the optimal shading position according to the angle of sunlight, breaking through the angle limitations of traditional fixed sunshades, significantly improving the adaptability and comfort of the sunshade function, and meeting diverse environmental needs.

[0033] In this embodiment, the outer helmet 1 includes a helmet body 11, a fixing ring seat 218 is fixedly installed at the bottom of the helmet body 11, and the inner helmet 211 is fixedly connected to the helmet body 11 through the fixing ring seat 218 and installed inside the helmet body 11. Bushings 12 are fixedly installed on both the left and right sides of the helmet body 11, and a face mask 13 is rotatably installed on the front side of the helmet body 11 through the bushings 12. A locking strap 14 is fixedly installed at the bottom of the helmet body 11.

[0034] By integrating the fixing ring seat 218 into the bottom of the helmet body 11, a compact connection between the inner helmet 211 and the helmet body is achieved, optimizing the utilization of the helmet's internal space. The design of the bushing 12 and the rotatable visor 13 ensures the protective function while preventing interference between the sun visor and the visor when stored.

[0035] In this embodiment, the drive unit 22 includes a round seat 221 fixedly installed on both the left and right sides of the inner helmet 211. The round seat 221 has a hollow groove 222 inside, and a turntable 223 is rotatably installed inside the hollow groove 222. A connecting block 224 is fixedly installed on the top of the turntable 223, and an arc-shaped connecting rod 225 is fixedly installed on the top of the connecting block 224. A rotating torsion column 226 is installed through the outer wall of the round seat 221. One end of the rotating torsion column 226 passes through the helmet body 11 and the round seat 221 and extends to the side of the turntable 223 and is fixedly connected thereto. The rotating torsion column 226 rotates inside the bushing 12.

[0036] The rotating torsion column 226 converts the rotational motion into the arc-shaped linear displacement of the sunshade 217 through the transmission mechanism of the turntable 223 and the arc-shaped connecting rod 225, so that the state switching can be completed by one hand.

[0037] In this embodiment, one end of each of the two arc-shaped connecting rods 225 on the left and right sides of the inner helmet 211 is fixedly connected to both ends of the arc-shaped fixing rod 216, thereby realizing the linkage between the sliding unit 21 and the driving unit 22, and enabling the driving unit 22 to drive the sliding unit 21 to move.

[0038] The arc-shaped connecting rods 225 on the left and right sides are rigidly connected to the two ends of the arc-shaped fixed rod 216, forming a symmetrical power transmission system, which can be driven and operated from both sides.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] During operation, firstly, in the sunshade state, the operator rotates the rotating torsion column 226, which drives the turntable 223 to rotate. The turntable 223 drives the arc-shaped connecting rod 225 to rotate through the connecting block 224. The arc-shaped connecting rod 225 drives the arc-shaped fixed rod 216 to move forward in an arc shape, which in turn drives the sunshade 217 to move in an arc shape. The sunshade 217 moves out of the helmet body 11 through the arc-shaped through groove 219. The sunshade 217 is bent to connect with the wire 2110 to achieve sunshade.

[0041] Then, when the helmet is in the correct position, the rotating torsion column 226 is rotated in the opposite direction, so that 2177 is retracted into the space between the helmet body 11 and the inner helmet 211. The sun visor 217 is pulled down, so that the face mask 13 rotates in an arc shape, thus achieving the helmet position.
