Abstract
The utility model relates to an external asymmetric blind zone eliminated rear-view mirror, which belongs to optical viewing device of vehicles. The mirror surface of the rear-view mirror is formed by the smooth transition of six parts, wherein the six parts are principal planes at the middle and upper parts and curved surfaces at the lower part and at the left and right sides. The area of the principal plane part accounts 30 to 50% of the forward projected area of the entire rear-view mirror, an angle between the curved surface at the lower part of the mirror surface and the principal planes at the middle and upper parts is at least 45 DEG, and the biggest included angle of the curved surface at the inner side and the principal plane part is at least 45 DEG. The mirror surface is asymmetrically designed to the center of the mirror surface, and the width of the curved surface at the inner side is more than that of the curved surface at the outer side. The utility model uses a combinational design of planes and curved surfaces, enlarges visual fields, also keeps the advantage that images of the plane parts do not deform, and blind zones are eliminated or partially eliminated. The asymmetric design can properly widen the curved surface at the inner side of the rear-view mirror, curvature radiuses are enlarged simultaneously when the included angles are the same, and the deformation degrees of the images in the blind zone are reduced.
Description
Technical field
The utility model relates to the structure design of the external back mirror that a kind of automobile uses, and belongs to the vehicle optical finder.
Background technology
At present, the automobile rearview mirror major part of using in the prior art is still based on plane mirror.The advantage of plane mirror is that image is undistorted, but the visual field is narrow, especially can't see the blind area of Vehicular body front and vehicle both sides.In order to broaden one's vision, dead zone-eliminating, the vehicle mirrors that has adopt complementary surface or plane and curved surface combination.But all can not well eliminate or partly eliminate the blind area of Vehicular body front and vehicle both sides, make the driver can accurately judge driving road-condition.The advantage of curved surface is to have enlarged the visual field, and shortcoming is the serious distortion of image, sees not farly, and the driver can accurately judging distance from the image of curved surface, and is easy to generate dizzy.As long as there is curved surface in minute surface, the distortion of curvature portion image is exactly inevitable.
The content of utility model
The purpose of this utility model provides the asymmetric blind area back mirror that disappears of a kind of external, what can keep that plane mirror sees is far away, the undistorted signal advantage of image can be eliminated again to greatest extent or part is eliminated the blind area of Vehicular body front and vehicle both sides, makes the driver can accurately judge driving road-condition.
The purpose of this utility model is achieved by the following technical solution:
The asymmetric blind area back mirror that disappears of a kind of external, minute surface is combined by plane and curved surface two parts smooth transition, it is characterized in that: described minute surface by the principal plane of middle and upper part and bottom and left and right sides curved surface totally six part smooth transition combine, the area of its principal plane part accounts for 30%～50% of whole back mirror forward projection area.
In order to eliminate under the automobile sided mirror unit and the blind area at rear, the curved surface of described minute surface bottom and the angle between the principal plane of middle and upper part are at least 45 degree.
In order to eliminate the blind area before the headstock, the maximum angle of its inner curve and principal plane part is at least 45 degree.
Described minute surface is an asymmetric design with respect to this minute surface center, and the width of inner curve is greater than the width of outer N-Side surf.
The utlity model has following advantage and beneficial effect: adopt plane and curved surface unitized design to enlarge the visual field, elimination or part have been eliminated the blind area, comprise the blind area of automobile both sides and the blind area before the headstock.Because the plane has been adopted in the middle and upper part of minute surface, image is indeformable, and the driver can judge driving road-condition accurately; Asymmetric design can suitably be widened the curved surface of back mirror inboard, has strengthened radius of curvature when angle is identical, has reduced the deformation extent of this area image.Because between plane and the curved surface all are smooth and continuous, so image is continuous.
Description of drawings
Fig. 1 is the orthogonal projection scheme drawing of the utility model back mirror left side mirror minute surface.
Fig. 2 is the orthogonal projection scheme drawing of the right mirror minute surface of the utility model back mirror.
The specific embodiment
Further be illustrated below in conjunction with accompanying drawing:
This rear-vision mirror face by the curved surface of the principal plane 2 of middle and upper part and bottom and left and right sides curved surface totally six part smooth transition combine, Fig. 1 is forward projection's scheme drawing of back mirror left side mirror minute surface, the expression of the dotted line signal among the figure boundary on each several part curved surface and plane.Dotted line AB shown in the figure is a straight line, and this line also can be a curve, or the smooth combination of straight line and curve, adopts non-directional purpose to be to change the shared area of planar section.The area of its principal plane part 2 should account for 30%～50% of whole back mirror forward projection area.This is the zone that the driver often need observe, and this partial image is indeformable, is convenient to driver's distance between the judgment object accurately, and can not produces spinning sensation.The bottom of back mirror is a curved surface, be used to eliminate or partly eliminate the blind area of automobile both sides, this part curved surface comprises 4,5,6 three parts, is in order to eliminate under the automobile sided mirror unit and the blind area at rear, and the angle between this part curved surface and the plane, middle and upper part should be more than or equal to 45 degree.The inboard of back mirror (i.e. a side of close vehicle body) is a curved surface 3, be used to eliminate the preceding blind area of headstock (this moment, back mirror should be installed in the headstock place), for the blind area before the actv. elimination headstock, the maximum angle of this part curved surface and principal plane part also should be more than or equal to 45 degree.The back mirror outside is a curved surface that width is narrower, and the formed angle in this curved surface and plane does not have exacting requirements, and angle can be about 5～15 degree, and its purpose is to broaden one's vision.
The left mirror of automobile rearview mirror or right mirror itself is asymmetric for the center line of back mirror, adopt asymmetrical design, purpose is suitably to strengthen the width of back mirror inner curve, when identical angle, can increase the radius of curvature of this curved surface, reduce the deformation extent of image.But left mirror and right mirror can be symmetry or asymmetric each other.
Curved surface described in the utility model can be the curved surface of rule, as the part of regular curved surfaces such as the face of cylinder, sphere, ellipsoid surface, ring surface, circular conical surface, also can be custom-designed curved surface.The radius of curvature of each curved surface can be identical, also can be to reduce gradually from inside to outside.
Curvature portion can be made literal or graphical indicia, and the image that the warning driver should the zone does not show its actual distance.
This figure is depicted as the situation of left mirror and right mirror symmetry.Left side mirror and right mirror also can be asymmetric.
