[0030] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0031] like Figures 1-9 As shown, this embodiment provides a brim, including a helmet body 1, a brim body 2, a buckle assembly 3, and a top ventilation assembly 4.

[0032] The helmet brim body 2 includes a front brim member 21, two side connecting plates 22, and an insert plate 23. The two side connecting plates 22 are connected to both sides of the front brim member 21, and the insert plate 23 is provided in the middle of the front brim member 21. The helmet body 1 has a first mounting groove on both sides and a second mounting groove on the top of the helmet body 1.

[0033] The buckle assembly 3 includes two sets of lateral snap-fit ​​components, which are respectively disposed in the first mounting slots on both sides of the helmet body 1. The lateral snap-fit ​​components include a fixed mounting plate 31 and a snap-fit ​​plate 32. The two fixed mounting plates 31 are installed in the first mounting slots on the left and right sides of the helmet body 1, and the two snap-fit ​​plates 32 are respectively installed on the inward side of the two side connecting plates 22 near their ends. The fixed mounting plates 31 and the snap-fit ​​plates 32 are snapped together by pushing. Specifically, a notch 311 is formed in the middle of the fixed mounting plate 31, and rails 312 are formed on the upper and lower sides of the notch 311. A sliding groove 3121 is formed on the two rails 312 facing each other. An elastic plate 313 is formed on the left or right side of the notch 311, and the elastic plate 313 is inclined outward from the fixed mounting plate 31.

[0034] A through hole 321 is formed on the buckle plate 32. Protrusions are formed on the upper and lower sides of the through hole 321. A slider 3221 is formed on the outward side of the protrusions. A pressing plate 323 is provided in the through hole 321. A pressing block 3232 is formed on the inward side of the pressing plate 323. A pressing relief hole is formed on the side connecting plate 22. The pressing relief hole corresponds to the through hole 321. The pressing block 3232 is used to press the elastic plate 313. Preferably, a pressing post 3231 is formed on the outward side of the pressing plate 323. The pressing post 3231 extends out of the pressing relief hole. In this embodiment, the pressing post 3231 is a prism with a rectangular cross-section. The shape of the pressing relief hole is adapted to it. The shape of the pressing post 3231 can be adjusted according to actual needs and cost conditions. After the slider 3221 of the buckle plate 32 is assembled with the sliding groove 3121 of the fixed mounting plate 31, the end of the elastic plate 313 extends into the through hole 321 and abuts against the side wall of the through hole 321.

[0035] Preferably, the two sides of the protrusion are connected by a connecting plate to form a protrusion frame 322. The end of the elastic plate 313 extends into the protrusion frame 322 and abuts against the side wall of the protrusion frame 322. By forming a protrusion frame 322 between the protrusion and the connecting plate, the elastic plate 313 does not need to be inserted into the through hole 321 to achieve locking and abutting, reducing the tilt angle and deformation of the elastic plate 313.

[0036] The top ventilation component 4 is disposed in the second mounting slot. The top ventilation component 4 includes a base 41, a push plate 42 and a top cover 43. A ventilation hole is formed on the top of the helmet body 1, and a corresponding hole is formed on the base 41. Specifically, a protruding ring is formed below the corresponding hole. The protruding ring extends into the ventilation hole and is locked, which plays a limiting role. The base 41 is installed above the helmet body 1 and the corresponding holes and ventilation holes are aligned. The top cover 43 is placed on top of the base 41. An air inlet 11 is formed on the front side of the top cover 43. A cavity is formed between the top cover 43 and the base 41. The push plate 42 is placed in the cavity and is slidably connected. A baffle 423 is provided on the front side of the push plate 42. The baffle 423 is adapted to the air inlet 11. An operating port is formed on the upper surface of the top cover 43. The push plate 42 controls the connection and blockage between the ventilation port and the air inlet 11 by moving back and forth. Specifically, a push-pull protrusion 424 is formed on the upper surface of the push plate 42. The push-pull protrusion 424 extends out of the operating port. The push plate 42 is moved by the push-pull protrusion 424 to realize the connection and blockage between the ventilation port and the air inlet 11.

[0037] Preferably, a through hole is formed on the base 41, and a deformation frame 411 is provided at the through hole. There is a deformation gap between the deformation frame 411 and the helmet body 1. A protrusion 412 is formed on the deformation frame 411. A limiting strip 421 is formed on the lower surface of the push plate 42. The limiting strip 421 contacts the protrusion 412. A limiting recess 422 is formed in the middle of the limiting strip 421. The limiting recess 422 is adapted to the upper surface of the protrusion 412. The setting of the limiting recess 422 and the protrusion 412 can ensure that the push plate 42 will not move due to shaking and gravity factors in the ventilation state, causing the baffle 423 to block the connection between the ventilation port and the air inlet 11.

[0038] A clearance opening is formed at the rear end of the top cover 43, and a plug plate 413 is formed at the rear end of the base 41. The plug plate 413 is located at the clearance opening. A plug hole 414 is provided on the plug plate 23. A plug plate 23 is formed in the middle of the front visor 21. A plug 231 is provided at the end of the plug plate 23. The plug 231 is adapted to the plug hole 414. Specifically, the plug 231 includes a connecting part 2311, an inclined part 2312, and a locking part 2313. The upper end of the inclined part 2312 is connected to the rear end of the connecting part 2311. The locking part 2313 is connected to the lower end of the inclined part 2312 and extends rearward. A plug-in chamber is formed between the plug plate 413 and the helmet body 1. The plug hole 414 is located at the upper end of the plug-in chamber. The locking part 2313 extends into the plug-in chamber and abuts against the upper surface of the plug-in chamber to achieve locking. A clearance opening corresponding to the operating port is formed on the plug plate 23.

[0039] Installation principle: First, insert the plug 231 on the plug plate 23 into the socket 414 of the base 41. Then, press the front end piece 21 downward so that the plug 231 abuts against the upper surface of the insertion chamber and the two side connecting plates 22 move to one side of the fixed mounting plate 31. Then, align the slider 3221 on the buckle plate 32 on the side connecting plate 22 with the sliding groove 3121 on the surface of the track 312 on the fixed mounting plate 31, and then insert it and move it to the bottom. During the movement, the elastic plate 313 will be abutted by the convex frame 322 and deform inward until the elastic plate 313 is located inside the convex frame 322. Then, the elastic plate 313 will reset and extend into the convex frame 322 to abut against the side wall of the convex frame 322 to achieve locking.

[0040] Tripping principle: Press the pressing post 3231 on the side connecting plate 22, the pressing plate 323 deforms, the pressing block 3232 presses the elastic plate 313, causing it to exit the convex frame 322, and then pull the side connecting plate 22 outward to achieve tripping. Finally, pull the plug 231 out of the socket 414.
