Abstract

The utility model relates to a double-reflecting surface non-blind zone rear-view mirror for a motor vehicle which comprises a shaped reflector. The reflecting surface of the reflector is composed of a main reflecting surface and a secondary reflecting surface which are connected with each other, the main reflecting surface is adjacent to one side of the motor vehicle, and the secondary reflecting surface is far away from one side of the motor vehicle. The length of the secondary reflecting surface is 20-40% of the length of the whole reflecting surface. Because the two reflecting surfaces are respectively aligned to the two reflecting regions of the rear of the motor vehicle, the blind area which is caused by the rear viewing of the single reflecting surface can be eliminated; the rear viewing without blind area can be realized. By using the main reflecting surface, the mirror image can be ensured to have the distortion of the minimal degree. The utility model is suitable for an automobile, and the utility model is also suitable for a motorcycle which can make a left handle and a right handle rotate.

Description

Double-reflecting face non-blind area back mirror

The utility model relates to the non-blind area back mirror of a kind of back mirror of automobile-use, particularly a kind of double-reflecting face.

In the prior art, the back mirror of automobile-uses such as automobile, motor bike mostly is the back mirror of single reflecting surface, and the blind area is arranged when being used for backsight.There is a kind of back mirror to adopt the bigger complex-curved reflecting surface of curvature, then causes the big distortion of mirror image to eliminate the backsight blind area.

The purpose of this utility model is to provide a kind of back mirror of double-reflecting face, both can eliminate rear view mirror blind zone, does not cause excessive mirror image distortion again.

In order to achieve the above object, the utility model adopts following technical proposals: the same catadioptre that includes a formation of lots with prior art of the utility model.The reflecting surface that it is characterized in that catadioptre constitutes by linking to each other with secondary reflector away from car one side near the primary reflection surface of car one side, and the length of secondary reflector is the 20-40% of entire emission face length degree.Because the reflecting surface of catadioptre has primary reflection surface and two reflecting surfaces of secondary reflector, can aim at latter two echo area of car respectively, thereby the non-blind area backsight is realized in the blind area can eliminate single reflecting surface backsight the time.The vision area of closer distance behind the primary reflection surface backsight car wherein, and longer-distance vision area behind the secondary reflector backsight car.

The primary reflection surface of above-mentioned reflecting surface and secondary reflector can be sphere, the radian of primary reflection surface sphere is 1000 °～2000 °, sphere radian for common used back mirror, guarantee the mirror image distortion of minimum degree, and the radian of secondary reflector sphere can be 600 °～900 °, though bigger mirror image distortion is arranged, it has or not vehicle or obstacle at a distance after being used to observe car, does not influence result of use; The length of secondary reflector is that 20～30% of entire emission face length degree gets final product, and is applicable on the automobile.

The primary reflection surface of above-mentioned reflecting surface and secondary reflector also can be the plane, and should have an angle between primary reflection surface and the secondary reflector this moment, and this angle is 110 °～170 °, and the length of secondary reflector is 30～40% of entire emission face length degree.The back mirror of this double-reflecting face is specially adapted on the motor bike that handle swings, and when handle was swung, catadioptre did not still lose its back vision function because of the secondary reflector that certain knuckle is arranged.

The utility model compared with prior art, have following conspicuous advantage: reflecting surface of the present utility model by two aligning cars after primary and secondary two reflecting surfaces of two echo areas constitute, can eliminate the backsight blind area, wherein primary reflection surface does not cause excessive mirror image distortion again.This double-reflecting face non-blind area back mirror is applicable on the various power actuated vehicles, also on the motor bike that swings applicable to handle, realizes the non-blind area backsight.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structural representation of an embodiment of the utility model.

Fig. 2 is the cutaway view at A-A place among Fig. 1.

Fig. 3 is the left view of Fig. 1.

Fig. 4 is the structural representation of another embodiment of the utility model.

Fig. 5 is the section-drawing at B-B place among Fig. 4.

Fig. 6 is the left view of Fig. 4.

An optimum implementation of the present utility model is: referring to Fig. 1, Fig. 2 and Fig. 3, be installed in the back mirror on the left side of car shown in the figure, structural principle is identical on the contrary mutually for the back mirror direction on the right.This back mirror includes the catadioptre 2 of a formation of lots, and its reflecting surface 3 constitutes by linking to each other with secondary reflector 1 away from car one side near the primary reflection surface 4 of car one side, and the length a of secondary reflector 1 is 30% of entire emission face 3 length l.Primary reflection surface 4 and secondary reflector 1 are sphere, and the radian of primary reflection surface 4 spheres is 1200 °, and secondary reflector 1 sphere radian is 800 °.

Another embodiment of the present utility model: referring to Fig. 4, Fig. 5 and Fig. 6, the primary reflection surface 4 and the secondary reflector 1 of this catadioptre 2 reflecting surfaces 3 are the plane, angle theta between primary reflection surface 4 and the secondary reflector 1 is 120 °, and the length a of secondary reflector 1 is 33% of entire emission face 3 length l.
