[0034] In this embodiment, Velcro 4 is fixedly connected to both ends of the helmet 1, a sponge lining 5 is arranged on the inner side of the helmet 1, and Velcro 6 is fixedly connected to both ends of the outer wall of the sponge lining 5, and the Velcro 6 is adapted to the Velcro 4. The arrangement of the Velcro 4 and the Velcro 6 facilitates the disassembly and cleaning of the sponge lining 5, and avoids the difficulty in cleaning sweat stains on the sponge lining 5.

[0035] In this embodiment, a reflective sticker 7 is fixedly connected to the rear end of the outer side of the helmet 1, and a plurality of air inlet holes 3 are provided on the helmet 1. The air inlet holes 3 facilitate ventilation of the helmet 1 and improve riding comfort.

[0036] Working principle: during use, after the helmet 1 is worn, in a natural state, the replaceable goggles 15 are located in the upper front of the helmet 1 and will not block the user's vision. When the replaceable goggles 15 are needed, the user can manually push the toggle block 32 to drive the second arc-shaped rack 28 to slide up. Through the setting of the gear 13, the first arc-shaped rack 9 with the replaceable goggles 15 is lowered to protect the user. At the same time, when the second arc-shaped rack 28 slides up, the elastic rope 30 is stretched to store a certain amount of elastic potential energy. When the iron block 34 at the rear end of the second arc-shaped rack 28 fits with the magnet 11, they attract each other, so that the elastic potential energy of the elastic rope 30 cannot be released. The magnetic force between the magnet 11 and the iron block 34 is slightly greater than the elastic force of the elastic rope 30. When the user is riding a bicycle and an accidental collision occurs and the helmet 1 falls, the helmet 1 will decelerate quickly with the user, and the counterweight block 3 Under the action of inertia, the helmet 1 moves forward, so that the iron block 34 of the counterweight 33 is separated from the magnet 11, and then under the action of the elastic rope 30, the second arc-shaped rack 28 slides quickly, driving the first arc-shaped rack 9 and the replaceable goggles 15 to shrink, so that the replaceable goggles 15 slide to the front upper part of the helmet 1, so that when the user falls or crashes, the replaceable goggles 15 will not be broken and cause the user's face to be scratched, which effectively protects the user's face safety. In different use environments, when the replaceable goggles 15 are needed for different purposes such as protection or sunshade, the rectangular clamping block 23 is pulled to separate the two insertion rods 24 from the first insertion hole 18, and then the rectangular clamping block 23 is rotated to make the rectangular clamping block 23 flush with the rectangular inserting block 35. At this time, the replaceable goggles 15 on the helmet 1 can be disassembled and replaced with suitable replaceable goggles 15, thereby improving practicality.
