Abstract
The utility model relates to an optics product, in particular to the rear view broad angle lens for automobile safety. The utility model is characterized in that on the structure foundation of the original card type fresnel magnifying lens, the lens thickness is designed into 0. 4 to 1. 5 mm, the mark space distance is 0. 3 to 1. 00 mm, the focal length is 200 to 700 and the viewing lens area is 0. 1m<2>-1m<2>. The magnification of the viewing field is 3 to 7 times. The rear view broad angle lens for automobile safety are made from plastic, such as the polyvinyl chloride material with thinness and convenience and convenient installation and also the view field of the driver is enlarged and thus the utility model plays a great function to for safety driving.
Description
Technical field
The utility model relates to optical goods, especially for the automotive safety backsight wide-angle eyeglass that can observe outside situation behind the car on the vehicle rear window glass with great visual angle.
Background technology
Vehicle rear-view mirror in the past all is that glass is made, and needs to guarantee certain Qu Guangdu, thereby eyeglass is thicker, and use is all inconvenient with storage, and cost height, and the easy fragmentation of shattering in the transportation are difficult for keeping and maintenance.Especially the backsight minute surface is very little, and the driver is difficult for seeing clearly, if paste a wide-angle viewing mirror on the car back window glass, observes outside situation behind the car, reduces the blind area, in the time of will drive a vehicle behind the car situation very clear, will give the driver and bring great convenience.The card form Fresnel eye gauge that once had plastics to make on the market, its structure be for being card form and transparent on the whole, the eye gauge zone of forming by Fresnel optics circle diagram lines on the one side, and another side is a burnishing surface.When reading newspaper, the elderly uses.
The utility model content
The purpose of this utility model is at above-mentioned defective, and a kind of automotive safety backsight wide-angle eyeglass that the automobile back is observed outside situation behind the car with great visual angle that is used for is provided.
The technical solution of the utility model is with the thick 0.4mm-1.5mm of being made as of sheet, and inter-ridge distance is 0.3mm-1.00mm, focal length 200 to 700, visor area 0.1m
2-1m
2The field range magnification factor is 3-7 times.
Said angular field of view top is 13 degree, and limit portion is 35 degree, and the bottom is 28 degree.
Said this mirror is to make with plastic material such as polyvinylchloride.
The utility model has the advantages that owing to can be attached on the vehicle rear window glass, can observe outside situation behind the car with great visual angle, reduce the blind area, situation comes into plain view behind the car during with driving, but the effect nation of amplification helps chaufeur to broaden one's vision, and guarantees safety.
Description of drawings
Further describe embodiment below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1,1-integral body, 2-eye gauge zone.Whole (1) is SMD, and is transparent, and one side is a burnishing surface, and another side is Fresnel optics circle diagram lines eye gauge zone (2), and its sheet is thick to be 0.4mm-1.5mm, and inter-ridge distance is 0.3mm-1.00mm, focal length 200 to 700, visor area 0.1m
2-1m
2, this mirror field range is amplified 3-7 doubly.This mirror is made of plastic, as pvc material.Burnishing surface is the light face, and during use, with car back window glass cleaning surfaces, the light face with this mirror pastes mutually with glass surface then, can use for a long time behind the size bubble in the crowded clean interlayer, and can not be out of shape.Just can see the situation of outside behind the car on the car rear window eyeglass during driver drives vehicle from the room mirror, field range is amplified 3-7 doubly, and chaufeur is broadened one's vision, and situation behind the car is come into plain view, and safe driving is had very big effect.Because field range enlarges 3-7 doubly, the visual field is also just same to be enlarged, and the object in the visual field then dwindles, but image is very clear.Make very thin lightly again with pvc material, dress pastes convenient.
