Abstract

The utility model discloses an automobile rearview mirror, comprising a mirror bracket and a mirror. The mirror is formed by connecting two or more intersected mirror surfaces; the mirror surfaces are in plane or arc structures. The utility model has the advantages of simple structure, easy manufacturing, enlarged back sight range, reduced accidents, and ensured driving safety.

Description

Automobile rearview mirror

Technical field

The utility model relates to a kind of vehicular spare parts, and more particularly, it relates to a kind of automotive rear-view lens device.

Background technology

At present, the minute surface of the automobile rearview mirror of Shi Yonging is single face big radian mirror minute surface or flat mirror minute surface on the market, available electronic or manual mode is adjusted before and after the mirror holder, upper-lower position and angle are adjusted the back viewed area, but because of mirror surface structure determines, back viewed area is confined to certain scope, is the blind area beyond the back viewed area.As shown in Figure 4, in the β zone visible area, the extra-regional γ of β zone is the blind area.Because the zone of blind area is bigger, chaufeur be can't see the vehicle in the blind area, exists the hidden danger of traffic accident.

Summary of the invention

The utility model has overcome deficiency of the prior art, and a kind of simple in structure, big automobile rearview mirror of back viewed area is provided.

Automobile rearview mirror of the present utility model mainly is made up of mirror holder and eyeglass, and described eyeglass connects and composes by the minute surface more than two or two is crossing.

Described eyeglass is planar structure or globoidal structure; The outer angle α of the exterior angle that described minute surface intersects or the string of a musical instrument is 3 ° to 15 °; Described minute surface garden arc radius R is 200mm to 1200mm.

Because the automobile rearview mirror that has adopted technique scheme, the utility model to provide has such beneficial effect and is: (1) is simple in structure, be easy to make, only need on the basis of former automobile rearview mirror, to change slightly, promptly can be made into; (2) enlarge the back viewed area, reduce traffic accident, guarantee traffic safety.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

In the embodiment shown in fig. 1, eyeglass 2 (length setting is 150mm, below two the example identical) be installed on the mirror holder 1; Eyeglass 2 is intersected by two plane mirrors to be formed with garden arc smooth connection, and joining is at 1/3rd places, the minute surface outside, and the exterior angle α of two Plane intersects is 10 °; Eyeglass 2 is glass-mirror or plastic electroplating minute surface; Mirror holder 1 is paid car body by connection and is connected, and available electronic or manual mode is adjusted before and after the mirror holder, upper-lower position and angle.

In second embodiment shown in Figure 2, eyeglass 2 is installed on the mirror holder 1; Eyeglass 2 is made up of two tangent connections of globoidal mirror, and string of a musical instrument joining is two point of contacts that the garden arc is tangent, and the point of contact is at 1/3rd places, the minute surface outside, and the string of a musical instrument exterior angle α of two garden arc points of tangency is 10 °; Two minute surface garden arc radius Rs ₁Be 700mm; R ₂Be 243mm.Other structures are identical with first embodiment.

In the 3rd embodiment shown in Figure 3, eyeglass 2 is installed on the mirror holder 1; Eyeglass 2 is made up of three mutual tangent connections of globoidal mirror, their joinings separately are two point of contacts that the garden arc is tangent separately, two points of tangency are respectively at minute surface 1/3rd places, the outside and 1/3rd places, minute surface inboard, and the string of a musical instrument exterior angle α of two garden arc points of tangency is 4.5 ° separately, α ₁It is 7 °.Three minute surface garden arc radius Rs ₁Be 1000mm, R ₂Be 468mm, R ₃Be 372mm.Other structures are identical with second embodiment.

In the optical principle of prior art automobile rearview mirror shown in Figure 4, in the β zone visible area, the extra-regional γ of β zone is the blind area.As shown in Figure 4, the zone, blind area of γ is bigger.

In the optical principle of first embodiment of automobile rearview mirror shown in Figure 5 and second embodiment, visible area is by vision area Φ and μ stack, the size of visible area is relevant with exterior angle or the outer angle α size of the string of a musical instrument that minute surface intersects, and α is big more, and visible area is big more, and the little visible area of α is also little; As shown in Figure 5, vision area Φ and μ stack are bigger than the vision area β of prior art, though also there is blind area γ ₁, but from Fig. 4 and Fig. 5 as can be known, blind area γ ₁Blind area γ than prior art is little; Because the prior art visible area enlarges, the blind area dwindles, and the thing in the rear view mirror blind zone that is in prior art originally now is in the viewing area.

In the optical principle of the 3rd embodiment of automobile rearview mirror shown in Figure 6, visible area is superposeed by vision area δ, λ and θ, in like manner, and the string of a musical instrument that the size of visible area and minute surface intersect outer angle α, α ₁Size is relevant, α, α ₁Big more visible area is big more, α, α ₁Little visible area is also little; As shown in Figure 6, visible area is bigger than the vision area β of prior art by vision area δ, λ and θ stack, also has blind area γ certainly ₂, Fig. 6 as can be known, blind area γ ₂Blind area γ than prior art is little; Equally, because the prior art visible area enlarges, the blind area dwindles, and the thing in the rear view mirror blind zone that is in prior art originally now is in the viewing area.
