However, the existing safety helmet is not firm enough and is easy to be damaged, and on the other hand, the existing safety helmet has poor air permeability and is not beneficial to being worn for a long time in a high-temperature environment.
In view of this, as shown in fig. 1 to 4, the present application provides a high impact helmet with an air permeation function, which includes an outer shell 100, a cushioning foam 200, and a protective mesh 300.
The outer shell 100 defines a head cavity for receiving the head, which, in addition to receiving the head of the user, also receives the cushioning foam 200 and the protective netting 300. The front end of the outer shell 100 is provided with a first air hole 110 communicated with the head cavity, the rear end of the outer shell 100 is provided with a second air hole 120 communicated with the head cavity, and the inner wall surface of the outer shell 100 facing the head cavity is provided with a reinforcing rib 130 extending from the front end to the rear end of the outer shell 100. The reinforcing ribs 130 can enhance the impact resistance of the outer shell 100 and enhance the safety of the helmet.
The cushion foam 200 is disposed in the head chamber of the outer case 100 and attached to the inner wall surface of the outer case 100. The shape of the cushion foam 200 is substantially similar to that of the outer case 100 to serve as a cushion when the head of the user is hit. The front end of the buffer foam 200 is provided with a first through hole communicated with the first vent hole 110, the rear end of the buffer foam 200 is provided with a second through hole communicated with the second vent hole 120, the buffer foam 200 and the outer shell 100 jointly define a first vent passage 410, the first vent passage 410 penetrates through the first vent hole 110, the first through hole, the second through hole and the second vent hole 120, and the first vent passage 410 is located beside the reinforcing rib 130. The external air flows sequentially through the first vent 110, the first through hole, the first vent passage 410, the second through hole, and the second vent 120 to form convection inside the outer case 100.
That is, in the embodiment of the present application, the first air-permeable passage 410 and the second air-permeable passage 420 are provided by a structure in which the reinforcing ribs 130 protrude inside the outer case 100. There is the space that extends along strengthening rib 130 length direction between the left and right sides (the both sides of width direction) of strengthening rib 130 and shell body 100 and buffering foam 200, and this space is used for doing ventilative passageway, kills two birds with one stone, and strengthening rib 130 can strengthen the intensity and the rigidity of shell body 100 on the one hand, and on the other hand need not set up other structures and forms ventilative passageway (the structure of the strengthening rib 130 of ingenious utilization), has reduced manufacturing cost and processing degree of difficulty, also has the gas permeability simultaneously.
The protective net cover 300 is disposed in the head cavity for wearing on the head, and the cushioning foam 200 is disposed between the protective net cover 300 and the outer shell 100, and the upper end of the protective net cover 300 is spaced from the cushioning foam 200. The helmet in the embodiment of the present application is different from a general helmet. The helmet for construction only has the outer shell 100 and the protective net 300, and the helmet for riding only has the outer shell 100 and the cushioning foam 200. In the embodiment of the present application, safety and air permeability are considered, that is, the outer shell 100 is used, and the cushioning foam 200 and the protective net 300 are added at the same time. On one hand, the safety performance is stronger, and the shock resistance is stronger. On the other hand, external air can pass through the gap between the protective net 300 and the cushioning foam 200, so that heat on the head of a user can be taken away conveniently, and the air permeability is better.
Two first air holes 110 and two second air holes 120 are formed in the outer shell 100, two first through holes and two second through holes are formed in the buffering foam 200, the two first air holes 110 are communicated with the two first through holes in a one-to-one correspondence mode, the two second air holes 120 are communicated with the two second through holes in a one-to-one correspondence mode, two first air passages 410 are defined by the buffering foam 200 and the outer shell 100 together, the two first air passages 410 equally divide and respectively penetrate through the first air holes 110, the first through holes, the second through holes and the second air holes 120, and the two first air passages 410 are respectively located on two sides of the reinforcing ribs 130. The two air-permeable passages can make good use of the gap between the two sides of the plate of the reinforcing rib 130 to enhance the air-permeable performance.
Specifically, the stiffener 130 is located at a middle position of the outer case 100, and the width of the stiffener 130 is between one half and one quarter of the width of the outer case 100.
In order to improve the air permeability, two grooves are formed on the cushioning foam 200, and the two grooves respectively extend from a first through hole to a second through hole. The configuration of the groove may increase the cross-sectional area of the first air-permeable passage 410.
In one embodiment, the protective netting 300 has a plurality of air permeable grids disposed thereon. Of course, in other embodiments, there may be only one air permeable mesh 310.
The protective netting 300 may be attached to the cushioning foam 200 and also to the outer shell 100. Therefore, in one embodiment, the outer peripheral side of the protective mesh 300 is connected to the cushion foam 200. In another embodiment, the outer circumferential side of the protective netting 300 is connected to the outer case 100.
When the protective net cover 300 is connected to the cushioning foam 200, the outer circumferential side of the protective net cover 300 is provided with an outwardly extending annular abutment flange which abuts the outer circumferential side of the cushioning foam 200 and completely covers the outer circumferential side of the cushioning foam 200. Specifically, the outside of the butt flange of the protective net cover 300 is connected with a plurality of flanges 320 extending towards the head cavity, the portion of the peripheral side edge of the buffer foam 200 close to the outer shell 100 is provided with a plurality of clamping grooves, each clamping groove defines a bayonet with the outer shell 100, each flange 320 is clamped at the bayonet (it can also be understood that the flange 320 extends over the side edge of the buffer foam 200 and is clamped between the buffer foam 200 and the outer shell 100), so that the protective net cover 300 is connected to the buffer foam 200. The external air flow may sequentially pass through the first vent 110, the first through hole, the gap between the buffer foam 200 and the protective net 300, the second through hole, and the second vent 120 to form convection inside the helmet, so as to take away heat for the head.
According to some embodiments, the cushioning foam 200 and the protective netting 300 are all integrally formed structures.
The same or similar reference numerals in the drawings of the present embodiment correspond to the same or similar components; in the description of the present application, it is to be understood that if there is an orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. based on the orientation or positional relationship shown in the drawings, it is only for convenience of description and simplification of description, but it is not intended to indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and are not to be construed as limitations of the present patent, and specific meanings of the above terms may be understood by those skilled in the art according to specific situations.
