Technical Field

[0001] The utility model relates to the technical field of cycling helmets, in particular to a helmet with a ventilation structure. Background Art

[0002] During the use of cycling helmets, especially full-face helmets, the overall coverage of the head structure may lead to poor ventilation. Existing technologies solve the ventilation problem through the design of air inlets, air ducts, and air outlets. The existing technology for the gear design of the helmet air outlet only lies in adjusting the relative position of the cover plate and the air outlet holes, opening or closing more air outlet holes to adjust the ventilation volume. However, due to the size and shape of the ventilation hole structure being restricted by relevant design standards, overly large ventilation holes will affect the safety performance of the helmet.

Detailed Embodiment

[0020] The following combines the drawings and embodiments to further describe the detailed embodiments of the present invention. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention. Embodiment

[0021] As Figures 1 to 4 , a helmet with a ventilation structure includes a helmet body 1, an air inlet 2 opened in front of the helmet body 1, a rear air outlet 3 opened behind the helmet body, an air duct 4 arranged inside the helmet body 1, the air duct 4 extends from the air inlet 2 to the rear air outlet 3, and a switch is arranged at the air inlet 2; an upper air outlet 5 is also designed at the top of the helmet body 1, and the upper air outlet 5 is connected to the air duct 4; a mounting plate 51, a cover plate 52 and a baffle 53 are arranged outside the upper air outlet 5, the mounting plate 51 is arranged on the surface of the helmet body 1, and ventilation holes 512 are also arranged on the surface of the mounting plate, the baffle 53 is arranged on the cover plate 52 at a certain angle, and the cover plate 52 is buckled on the mounting plate 51.

[0022] Using the air duct 4 to connect the air inlet 2, the rear air outlet 3 and the upper air outlet 5 can effectively improve the ventilation effect of the helmet and adapt to situations with higher ambient temperatures such as in summer; using the baffle 53 to limit the air volume discharged from the upper air outlet 5 can adapt to situations with lower ambient temperatures such as in winter.

[0023] As Figures 4 to 5 , a protrusion 54 is designed at the edge of the cover plate 52, a chute 55 suitable for the protrusion 54 is arranged on the mounting plate 51, and the protrusion 54 can cooperate with the chute 55 to enable relative movement between the cover plate 52 and the mounting plate 51; the protrusion 54 is a buckle.

[0024] Through the design of the protrusion 54 and the chute 55, the opening and closing of the upper air outlet 5 can be controlled. Specifically, the relative movement of the cover plate 52 with respect to the mounting plate 51 can be used to select whether the ventilation holes 512 are in communication with the air, and setting the protrusion as a buckle structure is easy for production and maintenance.

[0025] As Figures 4 to 6, the end of the baffle 53 is connected to the cover plate 52 through a rotating shaft 56. The baffle 53 is fixed on the rotating shaft 56. The rotating shaft 56 is also connected with a first bevel gear 57. The axis of the first bevel gear 57 coincides with the rotating shaft 56. A transmission shaft 58 is also arranged on the cover plate 52. A second bevel gear 59 is fixedly arranged on the transmission shaft 58. The second bevel gear 59 meshes with the first bevel gear 57; the baffle 53 includes a main baffle 531 and a secondary baffle 532. A convex block 510 is also designed at the part where the main baffle 531 is connected to the rotating shaft 56. A groove 511 suitable for the convex block 510 is arranged in the mounting plate 51; the shape of the convex block 510 includes a hemispherical surface, and the groove 511 includes a hemispherical surface.

[0026] Using the first bevel gear 57, the transmission shaft 58 and the second bevel gear 59 to connect the main baffle 531 and the secondary baffle 532, only the main baffle 531 can be adjusted to realize the adjustment of all baffles. At this time, the main baffle 531 also has the effect of a baffle adjustment switch. By arranging a convex block 510 at the part where the main baffle 531 is connected to the rotating shaft 56 and arranging a groove 511 suitable for the convex block 510 in the mounting plate 51, when the main baffle 531 is rotated, the convex block 510 is stuck into the groove 511, and the gear adjustment of the baffle 53 can be realized, so as to achieve the purpose of more refined control of the air volume.

[0027] It can be understood that the main baffle 531 and the secondary baffle 532 are only relative concepts in this embodiment. All baffles 53 can be designed with convex blocks 510 and matched with the grooves 511 of the mounting plate 51. However, too many convex blocks 510 and grooves 511 will bring unnecessary resistance and affect the design effect; in addition, setting the baffle 53 closest to the front end of the helmet body 1 as the main baffle 531 can make the operation of the wearer more convenient.

[0028] To make the gear adjustment smoother and reduce wear, the shape of the convex block 510 can be set as a hemispherical surface. Similarly, the groove 511 can also be set as the shape of a hemispherical surface.

[0029] The above is only the preferred implementation mode of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
