[0030] Specifically, the helmet carbon skeleton 300 is arranged through the plurality of ventilation grooves 101, which can enhance the structural strength of the helmet while maintaining the ventilation performance, improve the protection capability for the head, and since the central axis of the EPS lining 100 and the central axis of the helmet carbon skeleton 300 coincide with each other, the distribution of force is more uniform when the helmet is impacted, and the local concentrated stress is reduced, thereby improving the protection performance of the helmet.

[0031] Further, the EPS lining 100 is provided with a plurality of ventilation grooves 101, and the settlement part 3021 on the helmet carbon skeleton 300 is located between adjacent ventilation grooves 101, so that the settlement part 3021 on the helmet carbon skeleton 300 is in contact with the EPS lining 100.

[0032] Specifically, the contact between the settlement part 3021 and the EPS lining 100 can increase the contact area between the carbon fiber sheet layer 302 and the EPS lining 100 and improve the connection strength therebetween.

[0033] Further, the ventilation grooves 101 extend from the front edge of the helmet to the top rear side.
