Back vision structure of protective helmet visor

Abstract

The invention relates to a rearview structure of a visor of a safety helmet, which comprises a visor body and three reflecting mirrors; a first reflecting mirror of the three reflecting mirrors is arranged at the rear part of the visor body, a third reflecting mirror is arranged at the front part of the visor body, and a second reflecting mirror is arranged on the visor body between the first mirror and the third mirror, therefore, the first mirror can reflect a rear image to the second reflecting mirror which can reflect the rear image to the third mirror; then, the third reflecting mirror reflects the rear image to the eyes of a user, thus leading the visor body to have rearview function.

Description

technical field [0001] The present invention relates to the rear view structure of the visor of the safety helmet. Background technique [0002] 1. There is a safety helmet on the market, such as Figure 6 As shown, the safety helmet includes a shell 6, a visor 4 and a goggle 9, each side of the shell is provided with a screw hole, and both sides of the visor are respectively provided with a hole 5 corresponding to the screw holes on both sides of the shell, the goggles Both sides are also respectively provided with a hole corresponding to the screw holes on both sides of the shell. Therefore, the visor of the hat and the goggles can be fixed on the screw holes on both sides of the shell through the holes through the shared screw; The accommodating space can be located in the accommodating space when the goggles are lifted up. [0003] 2. There is a brim of a safety helmet on the market, which is provided with fixing elements (usually three) of fixing buttons or holes, so t...

Problems solved by technology

[0006] Problem 1: The third mirror 13 of the above-mentioned three mirrors is arranged at the front part of the top in the channel, that is, the front edge of the helmet shell. This way makes the third mirror very close to the user's eyes, although it will make the The reflection image has the effect of magnification, but it will make the user see two kinds of images, the upper and the lower, at the same time. The upper is the reflected image of the rear, and the lower is the actual front image; the two images of the upper and the lower are easy to cause confusion. Let the user create an illusion, for example: there is a car approaching quickly from behind, if the user is distracted, he may mistakenly regard the car coming from behind as the car coming from the front and brake suddenly, so it is easy to cause the car behind to collide. Affect driving safety

[0007] Problem 2: To set up a channel on the upper part of the shell of the helmet, and then install three mirrors on the top of the channel, it will be more difficult to manufacture; and the shell of the helmet must be re-moulded, and its structure must be redesigned. Therefore, its development investment cost is relatively high; and when a part is damaged, the entire helmet may have to be replaced, which is not economical.

[0008] Problem 3: The three mirrors are located in the channel, making it difficult to clean and wipe
