Abstract
An internally watched external reference mirror for motor vehicle is composed of object lens, optical fibre and eye lens, and features that the image received by its object lens is transmitted via optical fibre to the eye lens installed on the front panel. Its advantages include convenient watch and high running safety.
Description
The present invention relates to a kind of self-propelled vehicle outside rear-view mirror, particularly a kind of internally watched external rear-view mirror of motor-driven vehicles.
The automobile design manufacturing is gradually improved, but the never change of the essential structure principle of its outside rear-view mirror promptly utilizes the line reflection characteristic work of light, and there is following shortcoming in it:
1, chaufeur should be watched the place ahead attentively under steam constantly, often watches car rear side situation by the outside rear-view mirror of car body two sides again.The drawback of doing like this is that sight line often departs from the place ahead.Though the time is very short, safety hazard also appears easily.If watching the outside rear-view mirror time is 1 second, the speed of a motor vehicle be 60 kms/hour, car has been advanced 16 meters in 1 second.
2, human eye is when watching object, when particularly watching a little object, gets used to sight line is focused on object itself, and retina is could imaging clear like this.And the scene that human eye must be watched the back by the reflection of minute surface when watching outside rear-view mirror, promptly sight line focuses on virtual image place behind the minute surface.Particularly for the outside rear-view mirror in the co-pilot seat outside, because of distance is far away, it is more inconvenient to watch.As shown in Figure 1.
For overcoming above-mentioned shortcoming, the invention provides a kind of can be behind car front panel direct viewing car the self-propelled vehicle outside rear-view mirror of situation.
Internally watched external rear-view mirror of motor-driven vehicles of the present invention partly is made up of objective lens, fibre-optic bundle and eyepiece, and eyepiece is placed in front panel and watches position easily.As shown in Figure 2.Its principle of work is:
The rear scene projects fibre-optic bundle and leads people's end (2) after objective lens (1) refraction is dwindled.Objective lens (1) is superimposed together by two convex lens, to dwindle focal length.The image that imports fibre-optic bundle (3) is by mouth (4) output, conducts to bevelled mirror (7) (effect of bevelled mirror is with image Rotate 180 ° on the one dimension direction) after the birefringence of planoconvex lens (5), (6) is amplified.Refraction back planoconvex lens (8) amplifies once more, is projected to eyepiece (9).Eyepiece (9) is convex lens, and lateral surface is frosted processing, forms the frosted glass surface.Conduct next image in outside ground glass surface imaging from inboard transparent area, its light ray propagation mode such as Fig. 3, Fig. 4, shown in Figure 5.
The area of conter of objective lens (1) should have certain brightness to guarantee the shown image of eyepiece greater than the area of eyepiece (9).In order to improve the delivery quality of image, the importing end of fibre-optic bundle and mouth respectively have a slice area greater than the fibre-optic bundle cross-sectional area, and plano lens that material is identical with it and light transmitting fiber end weld.
The invention has the advantages that simple in structure, dependable performance, the source of not consuming energy is watched conveniently, the objective lens installation site is flexible, even can be installed in tailstock portion, as shown in Figure 6, total width is reduced.Also can combine, both light-permeables of coated glass cover (10) promptly are set outside objective lens (1), can reflect the inside and outside dual-purpose of looking again with the outside rear-view mirror of existing type.As shown in Figure 7.

Fig. 1 is the use scheme drawing of existing outside rear-view mirror;
Fig. 2 is an eyepiece position scheme drawing of the present invention;
Fig. 3 is the light path scheme drawing of overlooking of the present invention;
