A motorcycle helmet mainly consists of components such as a shell, a buffer layer, a lining, and a face shield. The material of the lining is mainly flannelette, mesh fabric, etc., which improves wearing comfort, absorbs sweat and discharges moisture. The types of face shields are mainly divided into transparent lenses, sun visors, anti-fog lenses, etc., which play the role of protecting the eyes and preventing sand, flying insects, etc. from entering;

[0003] For this reason, the patent with the publication number CN102429369A discloses a motorcycle helmet, in which a windshield is provided above the installed transparent faceplate of the helmet, and the windshield is connected and communicated with an internal battery on the helmet through an internal circuit. Through the windshield, when riding a motorcycle wearing a helmet and encountering rain, the windshield can be conducted to scrape the rainwater on the transparent face shield, keeping the face shield in a transparent visible state, which is beneficial to safely riding a motorcycle;

[0004] The above-mentioned motorcycle helmet uses a windshield to keep the face shield in a transparent visible state when riding a motorcycle wearing a helmet and encountering rain. However, during the riding process, when encountering hot weather, long-term riding or the face shield getting fogged and the vision being blocked, it is necessary to open the face shield to increase air circulation and restore clear vision. Usually, it is necessary to manually lift the face shield, and the single-handed operation is difficult, which may distract attention during riding and increase safety risks. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-10 , an adjustable multi-mode motorcycle helmet provided by the present invention includes a helmet body 1 and a face shield 3 installed on the top thereof. An adjusting structure 2 is provided on one side of the helmet body 1, and connecting shafts 7 are provided on both sides of the face shield 3; the adjusting structure 2 includes an outer cylinder 21 installed on one side of the helmet body 1, and an activity shaft 22 is provided inside the outer cylinder 21. A sleeve 24 is provided on one side of the activity shaft 22, and a large disc 23 is connected to one side of the sleeve 24. A spring 25 is sleeved outside the activity shaft 22. A support plate 221 is provided at the middle position of the activity shaft 22, and a limiting block 222 is provided on the surface of the activity shaft 22 on one side of the support plate 221. Grooves are provided on the inner wall of the outer cylinder 21 outside the limiting block 222. A sliding structure is formed between the activity shaft 22 and the outer cylinder 21. An extrusion block 223 is installed on one side of the top of the activity shaft 22, and the extrusion block 223 is angled. Four straight grooves 241 are provided on the surface of the sleeve 24, and the four straight grooves 241 are equally spaced on the surface of the sleeve 24, and inclined grooves 242 are provided on one side of each of the straight grooves 241. Sliding structures are formed between the extrusion block 223 and the straight grooves 241 and the inclined grooves 242 respectively;

[0032] Refer to Figure 3 , Figure 8 , Figure 9 and Figure 10As shown, when it is necessary to open the face mask 3 during cycling, press the movable shaft 22 on one side of the helmet body 1, press the movable shaft 22 into the outer cylinder 21, so that the extrusion block 223 fixed thereto displaces inward. Since one side of the extrusion block 223 is angled, it will slide into the inside of the inclined groove 242 opposite to the inclined angle during displacement. A limit block 222 is provided on the surface of the movable shaft 22, and the limit block 222 is engaged and limited with the groove in the outer cylinder 21, so that the movable shaft 22 cannot rotate. Thus, by pressing and pushing the inclined groove 242 with the extrusion block 223, the sleeve 24 rotates. When the extrusion block 223 displaces to the innermost side, the sleeve 24 rotates 45°. At the same time, release the movable shaft 22, and under the action of the resilience of the spring 25, drive the movable shaft 22 to reset, so that the extrusion block 223 slides along 421 to the initial position;

[0033] One side of the large disc 23 is connected with a small disc 231, and first teeth 232 are provided at both ends of the small disc 231. Second teeth 235 are provided at both ends of the inner edge of the large disc 23, and the number of teeth of the second teeth 235 is the same as that of the first teeth 232. A gear 234 is provided at the bottom of the small disc 231, and the gear 234 is meshed with both the first teeth 232 and the second teeth 235. A connection groove 233 is installed on one side of the gear 234. A limit strip is provided outside the connection shaft 7 on one side of the face mask 3, and a limit groove is provided inside the connection groove 233. A sliding structure is formed between the connection shaft 7 and the connection groove 233;

[0034] Refer to Figures 6-8 As shown, when the sleeve 24 rotates 45°, since the sleeve 24 is fixedly connected to the large disc 23, when the sleeve 24 rotates, the large disc 23 rotates synchronously, so that the first teeth 232 on the small disc 231 inside it contact the gear 234. Since the first teeth 232 and the gear 234 are meshed, when the small disc 231 rotates, the gear 234 is driven to rotate simultaneously by the first teeth 232. And the connection groove 233 inside the gear 234 is connected to the connection shaft 7 on one side of the face mask 3. Thus, when the gear 234 rotates, the face mask 3 is driven to flip upward 45°, realizing the function of automatically opening the face mask 3. And when it is necessary to close the face mask 3, press the movable shaft 22 again so that the extrusion block 223 slides and presses the lower set of inclined grooves 242, driving the sleeve 24 and the large disc 23 to rotate 45° again. At this time, the second teeth 235 on the inner wall of the large disc 23 are meshed with the gear 234, causing the gear 234 to rotate in reverse. Thus, the face mask 3 is driven to close through the connection shaft 7. The specific design of the number of teeth of each group of the second teeth 235 and the first teeth 232 makes the gear 234 rotate 45° each time;

[0035] A cleaning cloth 5 is provided at the top of the helmet body 1. An outer shell 11 is provided on the outside of the helmet body 1, and a buffer layer 12 is adhered inside the outer shell 11. A lining 13 is provided inside the buffer layer 12, and magnets are embedded at the edges of the lining 13. An activity groove 15 is provided at the top of the lining 13, and a sliding structure is formed between the activity groove 15 and the face mask 3. A connection hole 14 is installed on one side of the buffer layer 12. One end of the cleaning cloth 5 close to the hook surface 4 is provided with a wool surface 6. The hook surface 4 is provided inside the activity groove 15, and an adhesive structure is formed between the hook surface 4 and the wool surface 6;

[0036] Referring to Figures 3-5 As shown, during the process of closing the face mask 3, a cleaning cloth 5 is provided inside the activity groove 15. When the face mask 3 is closed, the outer surface of the face mask 3 will pass through the bottom of the cleaning cloth 5. Under the friction of the bottom of the cleaning cloth 5, the dirt and blur on the surface of the face mask 3 can be wiped clean, achieving the function of automatic cleaning. Magnets are embedded at the edges of the lining 13, and metal sheets are provided at the corresponding positions of the helmet body 1. The lining 13 is quickly disassembled and assembled by magnetic adsorption. By directly pulling the magnet position of the lining 13, the disassembly of the lining 13 can be achieved, and the effect of being convenient for cleaning or replacement can be realized. At the same time, the face mask 3 is made of PC material with a certain elasticity. After the lining 13 is disassembled, directly press both sides of the face mask 3, so that the connecting shafts 7 are respectively separated from the connecting holes 14 and the connecting grooves 233, realizing the disassembly of the face mask 3. Multiple types of face masks 3 are provided, such as transparent, sunscreen or off-road special face masks 3. Different face masks 3 can be replaced according to needs to achieve the adjustable multi-mode of the helmet.
