Abstract

The utility model discloses a panoramic inside-view mirror for a motor vehicle, which comprises the inner reflective surface or the outer reflective surface of a mirror sheet. The utility model is characterized in that the mirror sheet is provided with at least one reflective surface for work. The radius of the spherical curvature of the inner reflective surface or the outer reflective surface of the mirror sheet is 330 mm to 860 mm. The utility model overcomes the disadvantage that the traditional plane inner-view mirror has a small visual field. The visual field of the panoramic inside-view mirror for a motor vehicle is expanded to more than five times the visual field of the plane inner-view mirror. The panoramic inside-view mirror for a motor vehicle is suitable for various automobiles. The utility model is used for clearly observing the dynamic situation in a carriage in order to solve a driver's problem of back view.

Description

A kind of panorama introscope of self-propelled vehicle

Technical field

The utility model belongs to the endoscope apparatus of using in the car, and specifically a kind of front upper place that is installed in the operator's compartment is observed in the car and the outer dynamic device of rear window when being used for the driver and driving.

Background technology

The introscope that the current mobility car uses mainly divides two kinds:

1, be simple flat plate glass chip introscope (inside and outside equal plane) (Fig. 1), low price.

2, the interior or outer reflecting surface of a kind of introscope of part motorcoach use in recent years adopts the common sphere introscope sheet (Fig. 2) of radius of curvature circular arc between 1000～1800 millimeters, this class eyeglass than the visual field range of planar optics improved 2～3 times but because of the restriction that is subjected to the eyeglass overall dimensions with block very big that the forward visibility reason can not do again, final or do not satisfy chaufeur and can observe the interior most of situation of full car, promote not open always.

Summary of the invention

For on the basis of traditional similar size of introscope sheet external form (similar area), field range is expanded 5～10 times than planar optics, reaching both broadens one's vision satisfies the range of observation of chaufeur, can more clearly observe again the purpose of observable dynamic change, new improvement project is proposed.

The technical solution of the utility model is: by changing most important technology essential factor---the technical parameter of eyeglass reflex arc curvature of face radius is realized visual field range and visibility.

The panorama introscope of this self-propelled vehicle comprises the interior reflective surface or the external reflectance face of eyeglass, it is characterized in that being provided with at least on the eyeglass reflecting surface of a work usefulness, and the sphere curvature radius of the interior reflective surface of its eyeglass or external reflectance face is 330 millimeters to 860 millimeters.

Positive effect of the present utility model is:

1, taximan particularly by panorama introscope of the present utility model, can very clearly observe back seat occupant's dynamic security situation, can effectively prevent unexpected potential safety hazard.Even the article that client's article are forgotten on the seat can be seen fully aware ofly.

2, sample of the present utility model only need come back through on probation on several cars, mini-bus, bus, chaufeur and one look the panorama introscope; just can come into plain view to the current intelligence in the car; needn't often later look last case, fundamentally solve the sorrow of back " Gu " of chaufeur.

The specific embodiment

Be illustrated below in conjunction with embodiment and accompanying drawing thereof:

Referring to accompanying drawing 1, this is the traditional introscope that uses at present, is made up of shell 2 and eyeglass 1, because the interior reflective surface A or the external reflectance face B of eyeglass 1 are the plane style, the observed visual field of is very narrow.

Referring to accompanying drawing 2, this is the common spheric glass of circular arc between 1000 millimeters～1800 millimeters at inner arc reflecting surface A that uses on the public transport Oversize vehicle or outer arc reflecting surface B sphere curvature radius in recent years, the easily manufactured cost of this class eyeglass is not high yet, but field range also has only 2～3 times on common plane eyeglass.

Referring to accompanying drawing 3, this is dolly type panorama introscope eyeglass 1 constructional drawing of the present utility model, the sphere curvature radius of its interior reflective surface A is that the sphere curvature radius of 400 millimeters or external reflectance face B is 402 millimeters, if adopt above-mentioned in any one reflecting surface of A or outer B just can play desirable result of use.

For the panorama introscope eyeglass that the public transport Oversize vehicle is used, the radius of curvature that the sphere curvature radius of its interior reflective surface can be taken as 800 millimeters or external reflectance face is taken as 802 millimeters.The inside and outside reflection of work usefulness can be chosen as required.

Fig. 4 is a concave lens structure.Its work reflecting surface is inner arc reflecting surface A (being concave surface).

Fig. 5 is the convex lens structure.Its work reflecting surface is outer arc reflecting surface B (being convex surface).

Claims

1, a kind of panorama introscope of self-propelled vehicle, the interior reflective surface (A) or the external reflectance face (B) that comprise eyeglass (1), it is characterized in that being provided with at least on the eyeglass (1) reflecting surface (A or B) of a work usefulness, the interior reflective surface (A) of its eyeglass (1) or the sphere curvature radius of external reflectance face (B) are 330 millimeters to 860 millimeters.
