[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Such as Figures 1-6As shown in the figure, a safety helmet with airbag protection includes a helmet body shell 10 as an installation carrier. Inside the helmet body shell 10, a hemispherical intake compartment 11 adapted to the helmet body shell 10 is installed. Inside the intake compartment 11, a soft rubber compartment 15 is provided, and inside the soft rubber compartment 15, a hemispherical airbag 13 is provided. Through holes 131 are evenly arranged inside the hemispherical airbag 13. Ventilation holes 12 are evenly provided on the outer and inner sides of the soft rubber compartment 15. The top of the through holes 131 communicates with the inside of the intake compartment 11 through the ventilation holes 12. A buffer spring 132 is arranged inside the through holes 131. A cotton webbing helmet liner 14 is arranged inside the soft rubber compartment 15, which has the function of ventilation. Inside the cotton webbing helmet liner 14, a cross buffer frame 16 is arranged, and the four corners of the cross buffer frame 16 are fixedly connected to the edge positions inside the helmet body shell 10. Intake holes 17 communicating with the inside of the intake compartment 11 are evenly arranged at the edge positions outside the helmet body shell 10. A control compartment 20 is installed at the tail end outside the helmet body shell 10, and a one-way intake valve 22 is installed at the output end of the control compartment 20. Through the one-way intake valve 22, external air can be stably transported into the inside of the hemispherical airbag 13. The output end of the one-way intake valve 22 communicates with the inside of the hemispherical airbag 13. A one-way exhaust valve 23 is installed at the top of the control compartment 20, and the input end of the one-way exhaust valve 23 communicates with the inside of the hemispherical airbag 13. Through the one-way exhaust valve 23, the air inside the hemispherical airbag 13 can be discharged to the outside. A control panel 24 is installed outside the control compartment 20.

[0028] In this embodiment, fixed shafts 30 are symmetrically installed on both sides of the helmet body shell 10, and a protective cover 31 is jointly hinged on the outer sides of the two groups of fixed shafts 30. When using this safety helmet on a rainy day, the protective cover 31 can be flipped to the top of the helmet body shell 10 to cover the top of the helmet body shell 10, preventing rainwater from entering the inside of the intake compartment 11 through the intake holes 17.

[0029] In this embodiment, one side of the two groups of fixed shafts 30 close to each other extends into the inside of the helmet body shell 10 and a chin strap 32 is jointly arranged. A regulator adapted to the chin strap 32 is arranged on the chin strap 32. Adjusting the chin strap 32 through the regulator helps to make the safety helmet fit more stably on the user's head.

[0030] In this embodiment, a number of support columns 18 are evenly installed at the inner bottom of the intake compartment 11, and the tops of the number of support columns 18 are fixedly connected to the inside of the helmet body shell 10, which helps to improve the stress capacity of the intake compartment 11, and thus can ensure the stability of the external air flowing through the inside of the intake compartment 11.

[0031] In this embodiment, a round hole is formed at the position near the input end of the micro air pump 21 at the bottom inside the control bin 20, and a circular filter screen is installed inside the round hole, which helps to filter the air entering the inside of the hemispherical airbag 13.

[0032] In this embodiment, an annular air-permeable pad 19 is installed at the edge position inside the cap body shell 10, and the caliber of the inner circle of the annular air-permeable pad 19 gradually decreases from bottom to top, which helps to make the contact part between the user's head and the inner edge of the safety helmet more comfortable after the user wears the safety helmet.

[0033] In this embodiment, a breathable soft cushion layer is arranged inside the cross buffer frame 16, and breathable holes are evenly formed on the surface of the cross buffer frame 16, which helps to improve the comfort during the contact between the user's head and the inside of the cross buffer frame 16, and the breathable holes help to blow the outside air to the contact part between the user's head and the inside of the cross buffer frame 16, so that the whole head of the user will not be too stuffy.

[0034] Working principle: Before use, connect the power supply. After the user wears the safety helmet, the safety helmet is stably worn on the head by tightening the chin strap 32. Then, the micro air pump 21 is controlled by the control panel 24 to input air into the inside of the hemispherical airbag 13. The outside air enters the inside of the hemispherical airbag 13 after passing through the one-way intake valve 22, thereby increasing the pressure inside the hemispherical airbag 13 and forcing the hemispherical airbag 13 to deform, causing the inner side of the hemispherical airbag 13 to expand and drive the cross buffer frame 16 to fit towards the user's head top. If there is too much air inside the hemispherical airbag 13, part of the air inside the hemispherical airbag 13 can be discharged to the outside through the one-way exhaust valve 23. The outside air enters the inside of the intake compartment 11 through the intake hole 17 during the movement of the user, and then passes through the ventilation hole 12 and the penetration through hole 131, and blows towards the user's head top through the gaps on the cotton woven belt cap liner 14, cooling the part of the user's head inside the safety helmet. When the top of the cap body shell 10 is impacted, the impact force applied to the cap body shell 10 forces both the hemispherical airbag 13 and the cross buffer frame 16 to deform, buffering the impact received by the cap body shell 10.
