[0029] The inner lining 1 refers to an internal buffer layer, and its main function is to absorb the impact force of external collision to protect the head. The inner lining 1 can be made of foam material or fibrous material. The outer shell 2 can be made of harder materials such as plastic or carbon fiber. If an accidental collision occurs, the outer shell 2 is the first line of defense to protect the head and is used to disperse the impact force. In some embodiments, the outer shell 2 is made of a translucent material.

[0030] See also Figures 2 to 4 As shown, the inner liner 1 is provided with a first inner air duct 11 penetrating therethrough and a connecting groove 12 communicating with the first inner air duct 11.

[0034] In some embodiments, at least two rows of the first inner air ducts 11 and at least two of the first connecting grooves 121 are located in the middle of the liner 1 .

[0035] In some embodiments, the lining 1 is provided with a flow channel 15, and the flow channel 15 is not connected to the wearing space 10 to prevent water from entering the wearing space 10, so as to achieve the waterproof performance of the helmet; when the helmet is worn, the water outlet 1521 of the flow channel 15 is arranged downward to allow the water in the flow channel 15 to flow out, preventing the increased amount of water from entering the wearing space 10, so as to improve the waterproof performance of the helmet.

[0036] In some embodiments, the flow channel 15 is recessed from the outer surface 14 to a certain depth but does not penetrate the inner surface 13. In some embodiments, a portion of the flow channel 15 may also be located inside the liner 1 instead of being exposed on the outer surface 14.

[0037] In some embodiments, the communication groove 12 may be a part of the flow channel 15 .

[0038] In some embodiments, the flow channel 15 includes a first flow channel 151 and a pair of second flow channels 152. The pair of second flow channels 152 are arranged on both sides of the liner 1, the first flow channel 151 is arranged on the rear side of the liner 1, the first flow channel 151 is connected to the pair of second flow channels 152, and when the helmet is worn, the water outlets 1521 of the pair of second flow channels 152 are both arranged downward.

[0039] In some embodiments, the first external air duct 21 is provided in plurality, wherein the projection of one of the first external air duct 21 on the inner liner 1 is located in the first flow channel 151 , and the projections of two of the first external air ducts 21 on the inner liner 1 are respectively located in a pair of the second flow channels 152 .

The communication groove 12 includes a pair of second communication grooves 122, which are respectively located on both sides of the liner 1 and respectively connect the second inner air duct 16 and the second flow channel 152 to increase the air permeability.

[0042] In some embodiments, the first connecting groove 121 extends from the rear side of the liner 1 to the front side of the liner 1 and connects the first flow channel 151 with the second inner air channel 16 .

[0043] In some embodiments, after the helmet is worn, the first flow channel 151 is tilted downward to the left and right sides of the helmet to facilitate water outflow and prevent water from entering the wearing space 10 after increasing, so as to increase the waterproof performance of the helmet.

[0044] In some embodiments, the first connecting groove 121 extends from the rear side of the liner 1 to the front side of the liner 1 and connects the first flow channel 151 with the second inner air channel 16 .

The first external air duct 21 is connected to the first internal air duct 11, so that the wearing space 10 is connected to the external space, so as to achieve the ventilation effect of the helmet. The projection of the entrance of the first external air duct 21 on the inner lining 1 is offset from the entrance of the first internal air duct 11. External wind can enter the first internal air duct 11 through the first external air duct 21, and then be discharged after taking away the heat of the head through the first internal air duct 11, so as to achieve the effect of ventilation; on rainy days, after rainwater enters the first external air duct 21, since the projection of the entrance of the first external air duct 21 on the inner lining 1 is offset from the entrance of the first internal air duct 11, rainwater cannot enter the first internal air duct 11, so as to achieve the purpose of waterproofing, so that the helmet is both ventilated and waterproof.

[0046] The first external air duct 21 may be provided in plurality, and the plurality of first external air ducts 21 may be provided at different positions of the outer shell 2, such as the front, rear, left, right, and top, and may have the same or different directions to increase the air permeability.

[0047] After the helmet is worn, the entrance of the first outer air duct 21 is located behind the entrance of the first inner air duct 11 , which has a better effect of preventing rainwater from entering the first inner air duct 11 .

[0048] The connecting groove 12 connects the first inner air duct 11 and the first outer air duct 21. The connecting groove 12 is easy to process and shape, and the size of the connecting groove 12 can be made relatively large, so the ventilation effect is better.

[0049] In some embodiments, the communicating groove 12 may also be replaced by a through hole.

A pair of second flow channels 152 extend forward of the liner 1 and are connected to the second internal air duct 16, so that the ventilation effect is better.

[0053] In some embodiments, the shell 2 includes a first outer surface 23 and a second outer surface 24, the second outer surface 24 covers at least a portion of the first flow channel 151, and the first external air duct 21 is provided on the second outer surface 24. After the helmet is worn, the second outer surface 24 is tilted downward relative to the first outer surface 23, which can prevent rainwater from entering the first external air duct 21, so as to prevent rainwater from entering the wearing space 10, thereby increasing the waterproof effect.
