[0002] At present, the helmets worn by people riding motorcycles, electric vehicles and racing cars are usually provided with air windows on the top or side of the helmet, so as to ventilate during driving. However, when the air window is designed to be long, the air window is jammed when pushed by one hand, which brings inconvenience to the driver. In order to overcome this problem, it is necessary to develop a new helmet ventilation structure, which can effectively solve the problem of jamming of the long ventilation opening during operation. SUMMARY

[0003] In order to overcome the shortcomings of the prior art, the utility model aims at providing a helmet air window structure capable of solving the problem of jamming of a long air window during operation.

[0005] Further, the surface piece is provided with a clamping groove 32 at both ends of the bottom, and the clamping groove 32 is embedded in the protruding part of the wire.

[0006] Further, the surface piece is provided with a clamping groove type buckle in the middle of the bottom, and the clamping groove type buckle is buckled in the fixing hole of the bottom piece and is embedded in the protruding part of the wire.

[0007] Further, the length of the clamping groove type buckle, the buckle and the clamping groove of the surface piece is less than the length of the fixing hole of the bottom piece, so that there is space for the surface piece to move up and down.

[0008] Further, the bottom piece is provided with a ventilation hole at the bottom, and the distance between the ventilation hole and the top of the bottom piece is greater than the distance between the bottom of the surface piece and the top of the bottom piece when the surface piece is pushed up, so that the ventilation hole is exposed when the surface piece is pushed up.

[0009] The utility model has the advantages that the bottom piece and the surface piece are connected through the wire, so that the surface piece of the air window can move up and down at both ends under the driving of the wire when pushed by one hand, and the problem of jamming of the long air window during operation is effectively solved.
