A slider 25 is provided inside the knob switch 24. A sliding groove 37 is provided on the rotating part 34, and the slider 25 extends into the sliding groove 37; when the knob switch 24 is rotated, the slider 25 inside the knob switch 24 rotates, and the rotation of the slider 25 drives the sliding groove 37 of the rotating part 34 to rotate, thereby causing the rotating part 34 to drive the sunglasses 30 to rotate along the rotating hole 35;

[0027] The goggles mount 21 is fixedly arranged on the helmet body 10. The goggles mount 21 is provided with an arc-shaped hollow groove 23. A buckle 22 adapted to the arc-shaped hollow groove 23 is further arranged on the inner side of the goggles 20. The goggles 20 and the goggles mount 21 are rotatably connected through the arc-shaped hollow groove 23 and the buckle 22.

[0028] By buckling the buckle 22 with the arc-shaped hollow groove 23, the rotational connection of the goggles 20 is realized, avoiding the connection of the goggles 20 to the helmet body 10 through a rotating shaft, thereby providing an operating space for the rotational adjustment of the rotary switch of the present utility model for the sunglasses 30; by arranging a slider 25 inside the rotary switch 24 and a sliding groove 37 on the rotating part 34, when the rotary switch 24 is rotated, the slider 25 is driven to rotate in the sliding groove 37. Due to the rotation of the slider 25, the sliding groove 37 will be stressed in a direction offset by a certain angle from the slotting direction, and then the sliding groove 37 rotates along the rotating hole 35. At the same time, the clamping groove 33 and the rotating part 34 drive the sunglasses 30 to rotate together.

The positioning block 26 can move along the positioning groove 27 and snap into the positioning hole 28.

[0030] Such as Figure 7 , a rotating handle 41 is arranged on the outer side of the rotary switch 24; the design of the rotating handle 41 is more ergonomic, making the rotary switch 24 easier to rotate. At the same time, when the diameter of the rotary switch 24 is 6 - 8 cm, it does not affect the aesthetics of the helmet and can also provide a relatively large torque, enabling the user to rotate it easily.

[0031] Such as Figure 2 and Figure 6 , a notch 29 is arranged on the edge of the arc-shaped hollow groove 23. The notch 29 is adapted to the buckle 22; the design of the notch 29 enables the goggles 20 to be easily separated and replaced axially on the goggles mounting plate 21.

[0032] Such as Figures 4 to 5 , baffles 38 are arranged on both sides of the sunglasses mount 31; the baffles 38 can limit the rotation angle of the rotating part 34 within a certain range, avoiding damage to the part structure caused by excessive rotation.

[0033] Such as Figure 1 , a decorative plate 42 is further arranged on the outer side of the rotary switch 24.

[0034] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
