Description
Technical field
The present invention relates to technical field of automobile parts, and in particular to a kind of multi-curvature rear view mirror lens.
Background technology
The automobile rearview mirror of general vehicle is plane mirror or the convex mirror of single curvature, generally existing visual field short of width
The problem of, or there are blind areas, or have image distortion, thus driver can not accurately disturbance in judgement object position and vehicle body and barrier
The distance for hindering object will seriously affect traffic safety.According to statistics, since rear view mirror blind zone causes traffic accident to account for about in China
30%.Therefore, the research topic that the small rearview mirror of a big visual field, small blind area, and image fault is instantly important how is designed.
It is different to be proposed many functions, external form as the important component on automobile on the market in recent years for rearview mirror
Product.The imaging effect of rearview mirror is related with the radius of curvature of minute surface, and radius of curvature is bigger, and image fault is smaller, but visual field model
It encloses also smaller；Conversely, radius of curvature is bigger, field range is also bigger, but image fault also can be serious.According to mirror shape
Difference, existing rearview mirror can substantially be divided into following a few classes：The first kind is plane mirror, and radius of curvature is infinity, image
It is undistorted, but field range very little, it is also easy to produce larger blind area, many inconvenience are brought to driving；Second class is single mirror, minute surface
Shape be single curvature convex mirror, it reduces plane mirror curvature mirror radius, its essence is using image fault as cost with
Expand field range；Third class is hyperbolic mirror.It is small mostly to install convex surface additional on plane mirror for double curvature rearview mirror on the market now
Justify mirror to realize, although it solves the contradiction of image distortion and visual field size to a certain extent, due to needing to drive
Person observes the region of different curvatures on minute surface, makes troubles to driving and judgement, while the design of two minute surfaces considerably increases
Cost, in appearance also unsightly.4th class is more Qu Jing, and its essence is 3/4 range is plane, outside 1/4 on the inside of minute surface
Range is the curved surface of curvature gradual change, and effect is roughly the same with hyperbolic mirror, and only two pieces of mirrors are put in a face, there are still
The problem of inconvenient observation, while also increasing the difficulty that driver judges vehicle body and obstacle distance.Such as application No. is
A kind of multi-curvature vehicle rearview eyeglass is disclosed in the patent of CN201220074757.1, eyeglass ontology includes first curvature portion
And torsion portion, first curvature portion radius of curvature are more than torsion portion, although this can solve distortion and blind area on surface
Contradiction, but near the minute surface stitching position of two different curvatures, radius of curvature variation is violent, can cause image distortion, drives
Member is difficult to the distance by rearview mirror accurately disturbance in judgement object.
The defect of existing rearview mirror becomes apparent on truck.Present rearview mirror of truck on the market is by 6 pieces of convex surface microscope groups

Mend the wide-angle lens below blind mirror and main rearview mirror.As the term suggests main rearview mirror main detection is wheel or more, parking stall 4m it
Region afterwards, its radius of curvature are R1800mm, and the larger distortion of field range is smaller；Front lower visor is mainly observed under Chinese herbaceous peony
Orientation is set, and is mended blind mirror and is mainly observed vehicle body bottom right side position, wide-angle lens is mainly used for making up the defect of main rearview mirror, for seeing
Examine wheel position.The radius of curvature of this three pieces of minute surfaces is about R200-300mm, and radius of curvature is smaller, and distortion is very serious.So
For entire backsight microscope group, although being learnt from other's strong points to offset one's weaknesses by multiple minute surfaces so that rearview mirror of truck almost realizes zero blind area, at
Image distortion is extremely serious, and driver will produce serious spinning sensation when observing, and it is dangerous to increase driving.
It can be seen from the above, many methods have been proposed for the improvement of car rear-view, however it is directed to truck backsight
The improvement of mirror is considerably less.In a practical situation, truck driver be mostly night or road conditions poor suburb, mountain area travel, more
The danger of plus driving, so proposing that a kind of improvement to rearview mirror of truck is extremely important.
