Detailed Implementation

[0035] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 10As shown, a helmet includes a shell 1. The shell 1 has a front vent 31 connecting its inner and outer sides. A cover 4 is movably mounted on the shell 1, comprising a cover body 41. The cover body 41 has a first guide portion 42 and a second guide portion 43. The shell 1 has a first guide groove 321 adapted to the first guide portion 42. The first guide portion 42 can slide along the first guide groove 321 and rotate relative to it. The shell 1 also has a second abutting wall 33 and a swing groove 34 adapted to the second guide portion 43. The second abutting wall 33 can abut against the second guide portion 43 and cause the cover body 41 to abut against it. On the helmet shell 1, a first positioning part 322 is provided in the first guide groove 321. The first guide part 42 can cooperate with the first positioning part 322 to fix the second guide part 43 relative to the second abutment wall 33, and make the cover body 41 cover the end of the front windshield 31, thereby restricting or preventing air from passing through the front windshield 31 and entering the helmet shell 1. Under the action of external force, the first guide part 42 can disengage from the first positioning part 322 and make the cover body 41 move to the side of the front windshield 31, so that the front windshield 31 can be exposed. The second guide part 43 can move in the swing groove 34 and make the cover body 41 rotate away from the front windshield 31.

[0037] In the above structure, the cover body 41 can move to the side of the front air window 31, exposing the front air window 31. During use, air can directly enter the helmet shell 1 through the front air window 31, which helps improve the helmet's breathability and reduce the temperature inside the helmet shell 1 during use. Furthermore, because the cover body 41 rotates away from the front air window 31, it can guide the airflow during use, improving the air intake efficiency of the front air window 31. The first guide groove 321, the second abutment wall 33, and the swing groove 34 facilitate the stable movement of the cover body 41 and the helmet shell 1. The first positioning part 322 facilitates the cover body 41 covering the front air window 31, preventing the front air window 31 from opening accidentally during use.

[0038] In this invention, the front windshield 31 is located at the front end of the helmet shell 1. When the user wears the helmet and rides, air will naturally enter the interior of the helmet shell 1 through the front windshield 31. The cover body 41 is located in front of the front windshield 31. When the first guide part 42 moves along the first guide groove 321, the cover body 41 can move above the front windshield 31. When the second guide part 43 moves in the swing groove 34, the lower side of the cover body 41 tilts upward.

[0039] In this invention, the helmet shell 1 is provided with auxiliary air holes 311 connecting the inner and outer sides of the helmet shell 1, and the cover body 41 covers the auxiliary air holes 311. The second guide part 43 is controlled to move in the swing groove 34, causing one side of the cover body 41 to swing away from the helmet shell 1, creating a gap between the cover body 41 and the helmet shell 1. The auxiliary air holes 311 are located on the side of the gap, allowing air to enter the helmet shell 1 through the gap and the auxiliary air holes 311. The auxiliary air holes 311 facilitate increasing the amount of air entering the helmet shell 1 during use, which helps improve the helmet's breathability and reduce the temperature inside the helmet shell 1 during use.

[0040] A hinge portion 323 is provided in the first guide groove 321. The first guide portion 42 cooperates with the hinge portion 323 to restrict the sliding of the first guide portion 42 along the first guide groove 321. The first guide portion 42 can rotate relative to the hinge portion 323 and allow the second guide portion 43 to swing in the swing groove 34. Under the action of external force, the first guide portion 42 can cooperate with or disengage from the first hinge portion 323. The hinge portion 323 facilitates the swinging of the second guide portion 43 in the swing groove 34 and prevents the free movement of the first guide portion 42 in the first guide groove 321 from affecting the swinging of the second guide portion 43 in the swing groove 34, making it convenient for the user to control the relative movement of the windshield 31 and the helmet shell 1.

[0041] Preferably, the swing groove 34 is provided with a plurality of second positioning parts 341. The second guide part 43 cooperates with the second positioning parts 341 to restrict the movement of the second guide part 43 in the swing groove 34. Under the action of external force, the second guide part 43 can disengage from the second positioning parts 341, thereby allowing the second guide part 43 to move along the swing groove 34 and allowing the cover body 41 to rotate relative to the helmet shell 1. The provision of the second positioning parts 341 facilitates the fixation of the second guide part 43 in the swing groove 34, preventing the cover body 41 and the helmet shell 1 from rotating freely during use and affecting the normal use of the helmet.

[0042] In this utility model, the cover body 41 near the helmet shell 1 is provided with a pressing protrusion 411. The pressing protrusion 411 extends in the direction of movement of the helmet shell 1 and can abut against the helmet shell 1 to support the cover body 41. The pressing protrusion 411 helps to reduce the friction between the cover body 41 and the helmet shell 1 when the cover 4 and the helmet shell 1 move relative to each other, making it easier for the user to flexibly control the cover 4 and make it easier for the user to use the helmet.

[0043] In this embodiment, at least two sets of second positioning parts 341 are provided in the swing groove 34. One set of second positioning parts 341 is provided at the end of the swing groove 34, and the swing groove 34 is provided at one end of the second abutment wall 33. The second guide part 43 is controlled to disengage from the second abutment wall 33, and the first guide part 42 is inserted into the swing groove 34 and cooperates with the set of second positioning parts 341. At this time, the cover body 41 is completely disengaged from the front end of the front windshield 31, and the abutment protrusion 411 at the lower part of the cover body 41 abuts against the helmet shell 1. The second guide part 43 is controlled to move in the swing groove 34, and the lower part of the cover body 41 is tilted upward, and the abutment protrusion 411 is moved away from the helmet shell 1. At this time, the cover body 41 not only facilitates the entry of air into the gap between the cover body 41 and the helmet shell 1, but also facilitates the entry of air into the front windshield 31.

[0044] The helmet shell 1 includes a detachably connected shell 2 and a connecting seat 3. A first guide groove 321, a second abutment wall 33, and a swing groove 34 are all disposed on the connecting seat 3. During the production of the helmet shell 1, the shell 2 and the connecting seat 3 are manufactured separately. This structure facilitates the production and processing of the first guide groove 321, the second abutment wall 33, and the swing groove 34, and makes the production and processing of the helmet shell 1 easier. Preferably, the shell 2 is provided with a fixing groove 21, and the connecting seat 3 is fixedly disposed in the fixing groove 21.

[0045] The front windshield 31 and the auxiliary air vent 311 are both mounted on the connecting seat 3. The housing 2 is provided with an air-avoiding groove 25 that communicates with the front windshield 31 and the auxiliary air vent 311. Air entering the front windshield 31 and the auxiliary air vent 311 can enter the interior of the helmet 1 through the air-avoiding groove 25.

[0046] In this embodiment, the connecting seat 3 is provided with a snap-fit ​​protrusion 36 and an elastic hook 37. The housing 2 is provided with a first snap-fit ​​portion 23 and a second snap-fit ​​portion 24 that are respectively adapted to the snap-fit ​​protrusion 36 and the elastic hook 37. Under the action of external force, the elastic hook 37 can disengage from the second snap-fit ​​portion 24, thereby allowing the snap-fit ​​protrusion 36 to disengage from the first snap-fit ​​portion 23. This structure facilitates the disassembly and installation of the housing 2 and the connecting seat 3, and facilitates the assembly, production, disassembly, and maintenance of the helmet shell 1. This structure is similar to the installation structure of a battery cover on an electrical appliance.

[0047] The main body 41 of the cover is provided with a third guide part 44, and the shell 1 is provided with a third abutting wall 35. The rotation center of the first guide part 42 during relative rotation in the first guide groove 321 is the first rotation axis. The second guide part 43 and the third guide part 44 are respectively provided on both sides of the first rotation axis. The second guide part 43 abuts against the second abutting wall 33, which allows the third guide part 44 to abut against the third abutting wall 35, and fixes the cover plate relative to the shell 1. By controlling the movement of the second guide part 43 in the swing groove 34, the third guide part 44 can move away from the third abutting wall 35. The arrangement of the third abutting wall 35 and the third guide part 44 facilitates the stable abutment of the cover body 41 against the shell 1, avoids the cover body 41 from deforming and tilting up during use, improves the aesthetics of the helmet, and also prevents air from entering the shell 1 through the tilted part of the cover body 41 in cold weather.

[0048] The helmet shell 1 described in this invention is provided with a through groove. The second guide portion 43 includes a protrusion 431 passing through the through groove. A retaining block 432 adapted to the retaining wall is provided on the side of the protrusion 431. The retaining block 432 and the cover body 41 are respectively provided on both sides of the through groove. The retaining block 432 abuts against the second retaining wall 33 and the cover body 41 abuts against the helmet shell 1. In this structure, the retaining block 432 is located inside the helmet shell 1, which avoids damage to the second guide portion 43 during use. Moreover, this structure facilitates the stable installation of the cover 4 and the helmet shell 1, and prevents the cover 4 and the helmet shell 1 from shaking during use.

[0049] The through-groove described in this utility model includes a first through-groove 22 and a second through-groove 312 respectively disposed on the shell 2 and the connecting seat 3. The first through-groove 22 and the second through-groove 312 are interconnected. The first guide part 42, the second guide part 43 and the third guide part 44 pass through the through-groove and enter the interior of the shell 1. The connecting seat 3 is provided with a connecting protrusion 32. The first guide groove 321 is disposed on the connecting protrusion 32. The connecting protrusion 32 passes through the first through-groove 22 and allows the first guide groove 321 to enter the shell 2. The connecting seat 3 is also provided with a plurality of protruding structures. The second abutting wall 33, the third abutting wall 35 and the swing groove 34 are all disposed on the protruding structures. The protruding structures pass through the first through-groove 22 and allow the second abutting wall 33, the third abutting wall 35 and the swing groove 34 to enter the shell 2.

[0050] The first guide groove 321 has an elastic groove 324 at at least one end. When an external force controls the engagement or disengagement of the first guide part 42 and the first positioning part 322, the elastic groove 324 can deform, causing the width of the first guide groove 321 to change. The elastic groove 324 facilitates the deformation of the first guide groove 321, preventing damage to the first guide groove 321 during engagement or disengagement of the first guide part 42 and the first positioning part 322, thus extending the service life of the helmet.

[0051] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
