Abstract

The utility model discloses a vehicle wing mirror without blind area which relates to an improved vehicle wing mirror. The vehicle wing mirror without blind area is an optics device which is composed of a non-coaxal magnifier or a coaxial magnifier and a concave curved surface reflector. The vehicle wing mirror without blind area is also composed of a non-coaxal magnifier or a coaxial magnifier, a plane reflector and a concave lens. An included angle is arranged between the magnifier and the reflector and can be regulated. The driver can visually observe the images of the objects at both sides of the vehicle on the concave curved surface reflector through the non-coaxal magnifier. The vehicle wing mirror without blind area completely eliminates the blind area at both sides of the vehicle and solves the problem that the objects in the blind area at both sides of the vehicle can not be visually observed.

Description

Power actuated vehicle non-blind area rearview mirror

The utility model relates to a kind of improved power actuated vehicle rearview mirror.

The existing power actuated vehicle particularly rearview mirror of automobile is mainly plane mirror (as Figure 13) or convex reflecting mirror (as Figure 14).The extensive application of convex reflecting mirror mainly is because it can enlarge driver's the visual field, thereby reduces the blind area of vehicle both sides.But, because the imaging in the convex reflecting mirror and exists bigger distortion less than plane mirror, make the actual distance between the correct judgment object of driver that certain difficulty be arranged, therefore, having limited convex reflecting mirror curvature can not be excessive, like this, the vehicle both sides still exist certain blind area.The existing method that solves the blind area is an electronics blind area detection system, promptly the blind area of vehicle body both sides is surveyed incessantly by electronics package, when having detected object and be present in the blind area, indicator lamp can be pointed out to the driver, but the shortcoming of this kind method is to carry out direct viewing to the vehicle both sides.

The purpose of this utility model is to eliminate the blind area of vehicle both sides, and solution can't be to the problem of vehicle both sides direct viewing, thereby reduces the generation of traffic accident.

The concrete technical scheme that realizes above-mentioned purpose is described below in conjunction with the accompanying drawings: improved on existing rearview mirror basis, a kind of non-blind area rearview mirror of mainly being made up of eye gauge 1, catadioptre 2, supporter 5 and housing 4 is provided, eye gauge 1 and catadioptre 2 are contained on the supporter 5, become angle between eye gauge 1 and the catadioptre 2, the setting value span at angle is 45 °～135 °, and eye gauge 1, catadioptre 2 and supporter 5 are contained in the housing 4 that has diffuser.

Eye gauge 1 and catadioptre 2 can be connected on the supporter 5 that has the ball groove by the spheroid that has cylinder 7 fixed thereon respectively, in the ball groove of this spheroid 7 on supporter 5, and employing flush fit, after the application of force, spheroid 7 can rotate in the ball groove, after removing power, spheroid 7 can keep relative position in the ball groove.

Angle between eye gauge 1 and the catadioptre 2 is adjustable, and it adjusts variation range between ± 10 °.

Eye gauge 1 can adopt non-coaxial or coaxial eye gauge, and catadioptre 2 can adopt convex surface catadioptre or convex reflecting mirror.

When eye gauge 1 adopted non-coaxial or coaxial eye gauge, catadioptre 2 can adopt plane mirror, and mounts concavees lens 3 at the CDEF of diffuser face.

Said non-coaxial eye gauge is meant that its focus is not positioned on the central axis of non-coaxial eye gauge, its principle such as Figure 11, the focus of common eye gauge is on the central axis of eye gauge (as Figure 10), if only get the part of eye gauge, the focus of this eye gauge is constant, and variation has taken place in the position of central axis, and promptly the focus of eye gauge no longer is positioned on the central axis, and having got a part of eye gauge so promptly becomes a non-coaxial eye gauge.

Said convex surface catadioptre is different from convex reflecting mirror.The shape of convex reflecting mirror is a part of taking off on sphere, and the shape of convex surface catadioptre can be described as a part of taking off on similar ellipsoidal surface, in other words conj.or perhaps in a part of rotating the curved surface that is become around its two-end-point line AE by a different smooth curve ABCDE (seeing Figure 12) of each section curvature.

The core of technical scheme provided by the utility model is with eye gauge and combination together, and the angle between the two can be adjusted in a big way, can make the driver observe imaging on catadioptre by eye gauge, that is to say driver observation to reality be become on the eye gauge upright, the virtual image of amplifying, be equivalent to install the catadioptre bigger than actual size in the vehicle body both sides, therefore, the convexity of catadioptre can be bigger, thereby enlarged driver's the visual field, dead zone-eliminating, and can observe vehicle after the body side intuitively, the pedestrian, the generation that can avoid traffic accident.This apparatus structure is simple, and is easy to adjust, is fit to batch manufacturing.

Implement the best mode 1 of this programme, 6 be described as follows in conjunction with the accompanying drawings: eye gauge 1 adopts non-coaxial eye gauge, and catadioptre 2 adopts the convex surface catadioptre.

Non-coaxial eye gauge 1 is contained in the hollow rectangle frame 8, one side of this rectangle frame 8 and one has spheroid 7 employings of small column and is suitable for the thread connection of dismounting, convex curve catadioptre 2 is installed on dull and stereotyped 6, dull and stereotyped 6 centers have the hole, in negative thread is arranged, dull and stereotyped like this 6 with spheroid 7 also be to pass through thread connection.The spheroid that connects non-coaxial eye gauge can be identical with the scantling of structure of this spheroid.

Supporter 5 by dull and stereotyped 5 ' and dull and stereotyped 5 " form by screw is fastening; dull and stereotyped 5 ' as and dull and stereotyped 5 " respectively to have two part spherical pores, like this when dull and stereotyped 5 ' and dull and stereotyped 5 " be fastened to a time-out by screw; just form two ball grooves; the diameter of the diameter of these two ball grooves and spheroid 7 is a flush fit; free to rotate when adding external force; as to keep ortho states to be advisable after removing power; to pass through the variation of spheroid 7 relative position in the ball groove like this, just can regulate the angle between non-coaxial eye gauge 1 and the convex surface catadioptre 2, the angle initialization value of is got 70 °, and the angle variation range is between ± 10 °.

The shell of this device can be made up of main body and diffuser two parts, connects (as connecting or clamping with screw) by removable method between the two.Base portion is a supporting body, and it is made by hard material (as plastics, metal etc.), but the foregoing supporter 5 of insert thereon.Diffuser is made by transmission substance (as glass, light-passing plastic etc.), and its function mainly is the cleaning that keeps the core apparatus of non-blind area rearview mirror.

Like this core apparatus shown in the accompanying drawing 5 is packed in the housing, be about to the supporter shown in the accompanying drawing 5 and be installed on the main body of shell, non-coaxial eye gauge is corresponding with the ABCF face of diffuser, has just formed a complete non-blind area rearview mirror.Embodiment 2: as above-mentioned non-blind area rearview mirror, substitute convex surface catadioptre 2 by a plane mirror, and the inner face of diffuser CDEF mount one with the equal-sized monoplane of face CDEF concavees lens, this structure also can be finished the function of non-blind area rearview mirror, its light path scheme drawing is seen Fig. 7.

Above-mentioned eye gauge and concavees lens also all can adopt Fresenl mirror (Fresnellense).

During use, substitute existing self-propelled vehicle rearview mirror with the non-blind area rearview mirror, the installation site is constant, about car each one, non-coaxial eye gauge is positioned near the vehicle window, (seeing accompanying drawing 9, accompanying drawing 10) takes away diffuser, can regulate angle between eyeglass, be as the criterion with the image that obtains being fit to oneself observe, refill diffuser, be a non-blind area rearview mirror that regulates.
