The utility model provides a lining structure of a wind guide type helmet, which comprises a lining body 10 matched with a head, wherein the inner surface of the lining body 10 is provided with a plurality of internal wind guide grooves 11 extending from the front end to the rear end of the lining body 10, and the outer surface of the lining body 10 is provided with a plurality of external wind guide grooves 12 extending from the front end to the rear end of the lining body 10; the internal air guide groove 11 and the external air guide groove 12 are distributed in a non-overlapping manner in the vertical direction.

In specific implementation, as shown in fig. 1 to 7, the lining structure of the air-guiding helmet includes a lining body 10 matched with the head, and preferably, the lining body 10 is made of engineering plastics. The inner surface and the outer surface of the lining body 10 are respectively provided with a plurality of internal air guide grooves 11 and external air guide grooves 12 extending from the front end to the rear end of the lining body 10, and the internal air guide grooves 11 and the external air guide grooves 12 are uniformly distributed on the inner surface and the outer surface of the lining body 10. As shown in fig. 4 and 5, the cross-sectional views of the lining body 10 are schematic, and the internal air guiding groove 11 and the external air guiding groove 12 are not distributed in a overlapped manner in the vertical direction, so as to avoid a problem that the total thickness of the lining body 10 is greatly weakened due to the overlapped distribution of the internal air guiding groove 11 and the external air guiding groove 12, and thus ensure the overall strength of the lining body 10.

In this embodiment, the internal air guiding grooves 11 include a plurality of spaced parallel grooves symmetrically disposed on the top and the lower edge of the lining body 10, and the external air guiding grooves 12 include a plurality of spaced parallel grooves symmetrically disposed on the top of the lining body 10. The distribution positions of the internal air guide grooves 11 and the external air guide grooves 12 can be set according to different user groups, for example, the distribution distance of the air guide grooves is short in a helmet special for children, the distribution distance of the air guide grooves is middle in a helmet for adult women, and the distribution distance of the air guide grooves is long in a helmet for adult men.

Preferably, the width of the external air guiding groove 12 is greater than the width of the internal air guiding groove 11, so that negative pressure is generated inside in the air flowing process, and the air flow rate is increased.

It should be noted that the internal air guiding groove 11 and the external air guiding groove 12 shown in the drawings of the specification are only shown to have a guide groove structure extending from a front end to a rear end, and the specific groove structure and distribution position are not limited.

According to the air guide type helmet lining structure provided by the utility model, the plurality of air guide grooves which are not vertically distributed in a staggered manner are arranged on the inner surface and the outer surface of the lining body, so that air can enter the helmet lining in an enlarged manner, and the purposes of ventilation and heat dissipation are realized. Not only improved the inside air mobility of helmet, increased the travelling comfort of wearing, still further improved impact resistance for the security performance is more excellent.

Preferably, the external air guiding groove 12 of the lining body 10 is provided with a plurality of air guiding holes 13 penetrating through the inner and outer surfaces.

During specific implementation, a plurality of air guide holes 13 penetrating through the inner surface and the outer surface are formed in the external air guide groove 12 of the lining body 10, and when a wearer uses the helmet, air enters the interior of the lining structure of the helmet from the external air guide groove 12 through the air guide holes 13, so that air circulation inside and outside the helmet is realized, and the heat dissipation and cooling effects are further improved. In this embodiment, the number of the air guiding holes 13 is 4, and the air guiding holes 13 are respectively disposed in the external air guiding grooves 12 at the left, right, front, and rear sides of the lining body 10, wherein each air guiding hole 13 can allow air at both sides to realize air convection, so that heat in the lining body 10 can be conveniently conducted out through the outside air. For example, when the wearer wears the helmet 10 and moves forward, the wind outside the helmet liner enters the interior of the liner body 10 from the wind guide holes 13 at the front end through the external wind guide grooves 12, and flows out from the wind guide holes 13 at the rear end to dissipate the heat. It should be noted that, in other embodiments of the present invention, the number of the air guiding holes 13 may be other, and specifically may be set according to the actual use requirement of the user, which is not limited herein.
