Abstract
The utility model provides an outside rear-view mirror for a vehicle. A plurality of surfaces with different curvature radii are smoothly connected, which forms the mirror surface of the outside rear-view mirror which is a composite curved surface. The curvature radii are more and more smaller from top to bottom. The curvature radius of the mirror surface at the upper half part is very big (and even is a plane surface). The curvature radii of the mirror surface at the lower half part are more and more smaller from top to bottom and from side to side. Therefore, a driver can see a far object from the mirror, the visual field for monitoring a nearby object is large with the mirror, and the mirror has no dead angle of visual field. The mirror surface or the mirror frame of the rear-view mirror can be marked with a reticle which stands for the distance from the latter and a vehicle with the outside rear-view mirror. The reticle can help the driver judge if the variation of a path or the turning is safe at the time.
Description
The utility model belongs to vehicle optical finder field.
Existing vehicle rear-view mirrors has two classes haply, and a class is the boss mirror.Another kind of is plane mirror or near the very big single radian convex lens of the radius of curvature of plane mirror.Though the former visual field face width, image distortion is more serious, and when treating that chaufeur is more clearly seen the image of sending a car later from mirror, it is very near from the distance of this car, thereby makes chaufeur carry out lane change or turn round safety hazard is arranged when handling.Though the latter has the advantage that image is true and look far, but the shortcomings such as dead angle that the visual field is narrow and can't see in the car body both sides (this shortcoming is particularly serious for large and medium-sized passenger vehicle and truck), difficulty when this has brought lane change or turning to chaufeur and dangerous, even therefore traffic accident takes place.Can see a long way off back car clearly in order to make back mirror, can see clearly again from the latter who gets closely, can see clearly near the car body both sides and locate, can see clearly again from car body both sides far away slightly, people once thought thousand and one way, wherein a way knowing of people is the most, make exactly back mirror direction can by chaufeur by handle some machineries or electrically operated device change.The shortcoming of this method is, need be provided with one and overlap comparatively complicated apparatus, and increase the operating performance of chaufeur, and is very inconvenient during use.
The purpose of this utility model is that the external big visual field of a kind of vehicle back mirror is provided.It need not set up any device, can obtain wide, no dead angle, the visual field and the higher effect of image definition.
Another purpose of the present utility model is on the basis of above-mentioned big visual field back mirror, to provide a kind of back that can show to send a car from the vehicle rear-view mirrors of this car approximate distance.
Technical solution of the present utility model is: the minute surface of this back mirror is the compound curved surface that the face slyness by a plurality of different curvature radius is formed by connecting, and radius of curvature is more and more littler from top to bottom.First half curvature mirror radius very big (even being the plane), lower part curvature mirror radius is not only more and more littler from top to bottom, and also is more and more littler from a side to opposite side.
Judge the approximate distance of back car for the ease of chaufeur from this car, can be at the markings of putting on the minute surface of this back mirror or on the picture frame on minute surface both sides through experimental calibration.
When the back car when this spacing is far away, its image appears in the first half minute surface of this back mirror, scene is more clear; Along with send a car shortening with this spacing of back, just toward moving down, because the aforementioned feature of lower part minute surface, chaufeur can therefrom monitor the car body both sides scope of broad all around to its image in mirror, i.e. big, no dead angle, the visual field.
Fig. 1 is the transparent view of a preferred embodiment of this vehicle rear-view mirrors eyeglass that proposes of the utility model application.
Fig. 2 is the section eyeglass figure that gets along the II among Fig. 1-II line.
Fig. 3 is marked with at picture frame to show that the back sends a car from the front elevation of this back mirror of the markings of this car approximate distance, on article one graticule among the figure (going up graticule) is the safety zone, article one, be the warning area between line and the second line, under the second line for forbidding lane change and turning round the district.When back car image appears at the safety zone, can carry out lane change safely and turn round operation; When back car image appeared at the warning area, chaufeur should be enhanced your vigilance when carrying out lane change and turning round manipulation; When back car image appears at the exclusion area, forbid carrying out the operation of turning round of lane change.
Claims (2)
1, a kind of vehicle rear-view mirrors, it is characterized in that the compound curved surface that minute surface is formed by connecting by the face slyness of a plurality of different curvature radius, radius of curvature is more and more littler from top to bottom, first half curvature mirror radius very big (even being the plane), the radius of curvature of lower part minute surface is not only more and more littler from top to bottom, and also is more and more littler from a side to opposite side.
2,, it is characterized in that safety zone, warning area and the exclusion area that is divided into by two graticules that show back car and this car approximate distance arranged on its minute surface or the picture frame according to the vehicle rear-view mirrors of claim 1.
