Abstract
The utility model relates to a double arc single-focusing wide-angle rear-view lens, particularly a reference mirror lens used on reference mirrors on two outer sides of an automobile. An upper and a lower moulds are integrally cast and formed, and a longitudinal curved surface is formed. After the longitudinal curved surface transversely extends on a smooth cambered surface section with a large diameter, then the back one third section of the longitudinal curved surface in a bending radian with a minor diameter gradually extends towards an outer side in a curved way and a double cambered surface section mirror surface is formed. A cambered surface section with a major diameter on the inner side of the longitudinal curved surface and a cambered surface section with a minor diameter on the outer side has two kinds of different radiuses, and in addition, the cambered surface section with the major diameter takes up two thirds of the longitudinal curved surface and the cambered surface section with the minor diameter takes up one third of the longitudinal curved surface. A connection section between the cambered surface section with the major diameter and the cambered surface section with the minor diameter are extended in a progressive way and centerlines of circular arcs of the two radiuses intersect at the same point. The utility model can enlarge the angle of a rearward sight line and reduce a blind spot on the sight line.
Description
The utility model relates to the burnt wide-angle rear-view mirror sheet of a kind of pair of arc list.
The lens structure of automobile rearview mirror of the prior art, the most original person is a simple eyeglass, but can only provide the suitable and limited field-of-view angle of one of apparent direction behind the steerman with it, surpasses this angle and just forms the dead angle blind spot that can't see.So have some car owners to stick a slice convex mirror, so that can see the visual field shadow thing of more lateral, with the auxiliary limitation of original back mirror on the visual field in the outside of back mirror; Yet because the convex mirror area that is sticked is little, though so it can see the angle than the outside, area is very little, effect is limited.
So the producer makes a kind of pair of arc wide-angle rear-view mirror sheet, please refer to the bulletin shadow basis of " dual wide-angle rear-view mirror " novel patent of checking and approving No. the 265708th, bulletin, No. the 84205222nd, application on December 11st, 1, the claim shown in the content of its bulletin is:
A kind of dual wide-angle rear-view mirror, it is one-body molded by having the differential of the arc eyeglass of arc surface curvature slightly, and the inboard former mirror portion and that accounts for most of area that includes accounts for than the super wide-angle in the outside of small size portion, and the former mirror portion's reservation and the same arc surface curvature of eyeglass of eyeglass, and it is characterized in that: the front end of this super wide-angle portion and former mirror portion have same arc surface curvature, its rear end then is made as the arc groove of an asymptotic former mirror portion in addition, make between super wide-angle portion and former mirror portion and have one every line, and because of the more former mirror of the arc surface curvature portion of super wide-angle portion is big, with the deficiency of auxiliary former mirror portion on the backsight visual angle, and reach the purpose that enlarges the backsight visual angle.
Yet that is as above lifted quotes the case structure as proof, please cooperate again and consult shown in its Fig. 4,6, the radian of its super wide-angle portion and former mirror portion differs widely, and each have their own center of arc, between is formed with together every line again, so will form the divided frame of two different proportion sizes on its visual field, so will form image dual not of uniform size shown in Figure 1 in this specification sheets, if and during reflected light rays, then form the glare phenomenon of dropping fire light easily, be easy to cause visual error to jeopardize the safety of driving with confusion.
Main purpose of the present utility model is to provide a kind of pair of arc list burnt wide-angle rear-view mirror sheet, and it is with the one die cast, has the die cast economic benefit of waste material not again easily.
A purpose more of the present utility model is to provide a kind of pair of arc list burnt wide-angle rear-view mirror sheet, when it uses on automobile in device, can enlarge the angle of rear sight line, reduces the blind spot on the sight line, to improve traffic safety.
Another purpose of the present utility model is to provide a kind of pair of arc list burnt wide-angle rear-view mirror sheet, and it can not form two cutting dual pictures that the division is clearly demarcated, can avoid forming Dual Images and the sight line confusion that causes, the situation that jeopardizes traffic safety take place.
The burnt wide-angle rear-view mirror sheets of two arc lists that provide according to the utility model, it is with upper and lower mould one die cast, it is after the level and smooth cambered surface section in the big footpath of one section of a vertical curved surface horizontal expansion, again in the back 1/3rd sections gradually with than the crooked cambered surface section of path laterally bending extension become two arc minute surfaces of less diameter and arc surface section, the big diameter and arc surface section of its inboard 2/3rds has two kinds of different radiuses with the path cambered surface section in the outside 1/3rd, linking section is between the two extended with progressive mode, and center of arc's line of two radius intersects at same point.
Aforesaid the utility model is with the one die cast, and the curved surface in the outside extends with identical radian and thickness, so die cast waste material not again easily; In addition, it is in device when using on automobile, can form suitable stretching out than the crooked radian of path to the sight line in two outsides, rear with its outside, and enlarge the angle of rear sight line, reduces the blind spot on the sight line, to improve traffic safety; Can not form two cutting dual pictures that the division is clearly demarcated with progressive the extension laterally between two different radian curved surface again, can avoid forming Dual Images and the sight line confusion that causes, the situation that jeopardizes traffic safety take place.
Existing conjunction with figs. is enumerated a specific embodiment, introduce structure content of the present utility model in detail and the function and benefit that can reach as after.
Fig. 1 is that illustration is implemented in the video picture of of the prior art pair of arc wide-angle lens.
Fig. 2 is a section of structure of the present utility model.
Fig. 3 is that illustration is implemented in video picture of the present utility model.
Structure section figure of the present utility model as shown in Figure 2, its be mainly with upper and lower mould one die cast be level and smooth cambered surface section 11 backs in the big footpath of one section of a vertical curved surface horizontal expansion, again in the back 1/3rd sections gradually with than the crooked radian of path laterally bending extension become two arc minute surfaces 10 of less diameter and arc surface section 12, though the big diameter and arc surface section 11 of its inboard 2/3rds has two kinds of different radiuses with the path cambered surface section 12 in the outside 1/3rd, but extend with progressive mode in linking section 13 between the two, and make center of arc's line of two radius intersect at same point.
Aforesaid the utility model is with one-body molded die cast, and the path cambered surface section 12 in the outside extends with identical radian and thickness, so die cast waste material not again easily; In addition, it is in device when using on automobile, as shown in Figure 3, can form suitable stretching out than the sight line in two outsides, 12 pairs of rears of crooked cambered surface section of path with its outside, and enlarge the angle of rear sight line, reduces the blind spot on the sight line, to improve traffic safety; Extend laterally with progressive between the cambered surface section 11,12 of two different radian again, can not form two cutting dual pictures that the division is clearly demarcated, can avoid forming Dual Images and the sight line confusion that causes, the situation that jeopardizes traffic safety take place.
In sum, the utility model has reached breakthrough structure really, has the author content of improvement, can reach the Practical Benefit than the tool progressive simultaneously again.
