Abstract

The invention relates to a rear-view structure of a safety cap brim, including a safety cap brim and two reflecting mirrors, wherein, the first mirror of the two reflecting mirrors is arranged on rear part of the cap brim, and the second mirror is arranged on the front part of the cap brim; thereby, the first mirror can reflect the rear images onto the second mirror, and then the second mirror reflects the images to eyes of the users, thus, the cap brim is provided with a function of back vision.

Description

technical field [0001] The invention relates to the rear view structure of the visor of a safety hat. Background technique [0002] 1. There is a safety helmet on the market, such as Figure 7 As shown, the safety helmet includes a shell 5, a visor 3 and a goggle 8, each side of the shell is provided with a screw hole, and the visor of the cap is respectively provided with a hole 4 corresponding to the screw hole 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 helmet on the market. The helmet includes a shell and a visor. The upper front edge of the shell is provided with fixing buckles (usually three)...

[0007] Question 2: the reflection of the above-mentioned three mirrors presents the rear "positive image", that is to say, the rear image seen by the user's eyes from the reflector (the third mirror 13) is a positive image; because the reflector (the third mirror 13) The third mirror) is very close to the front of the user's eyes (with a magnifying effect), so two images will appear in front of the user's eyes, one is the actual front image, and the other is the rear reflected image. When the above two images are "positive When the user is not paying attention, the user is likely to be confused by the two images in front of him and create an illusion. For example, if a car is 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 , it is so easy to cause a collision with the car behind, which affects driving safety

[0008] Problem 3: It is difficult to manufacture and produce a channel on the upper part of the helmet shell, and three mirrors on the top of the channel; the helmet shell must be re-moulded, and its structure must be redesigned, so its development The cost is relatively high; when a part is damaged, the entire helmet may have to be replaced, which is less economical
