Description
Technical field:
The utility model relates to automotive field, particularly relates to auto meter 3D scale illumination structure, particularly a kind of light guide structure for auto meter 3D scale.
Background technology:
Instrument is parts very important in automobile, directly can affect the impression of driver.Scale as an important element in instrument, for speed and the rotating speed instruction of instrument.Dial of meter is typically designed to plane formula, in prior art, dial scale (plane scale) is realized by the form of ink printing on dial plate, 3D scale in recent years as a very important design element adopt by increasing car load factory.There are special requirement in some car load factories for the illumination of 3D scale at present, require that the light sector of the illumination of 3D scale and other parts of dial plate separates, work as car door opening, chaufeur into the car time, 3D scale can light separately, and when chaufeur opens backlight, whole dial plate just lights together.And existing light structures provides independent illumination by not giving 3D scale, cause 3D scale illumination effect uneven.
Summary of the invention:
The purpose of this utility model is to provide a kind of light guide structure for auto meter 3D scale, the described this light guide structure for auto meter 3D scale will solve in prior art can not provide independent illumination to 3D scale, causes the technical matters affecting illuminating effect.
This light guide structure for auto meter 3D scale of the present utility model, this auto meter comprises pointer, scale case ring, dial plate, lamp-box frame and pcb board, described dial plate excircle is provided with dial scale, 3D scale is also provided with at described dial plate excircle, wherein, 3D scale light pipe is also provided with in described instrument, described 3D scale light pipe entirety is more than half toroidal, 3D scale is located on described 3D scale light pipe, 3D scale light pipe is corresponding at circumferencial direction with described 3D scale, the below at described 3D scale light pipe two ends is respectively equipped with a LED, otch is provided with at 3D scale light pipe and described 3D scale correspondence position.
Further, described 3D scale light pipe is made up of the light pipe of circular in cross-section or ellipse.
Further, described otch is positioned at the lateral surface of described 3D scale light pipe, and described 3D scale is positioned at the medial surface of 3D scale light pipe.
Further, described otch is formed by two facets are crossing, the axes normal of these two faceted intersection lines and described 3D scale light pipe.
Further, the bottom surface of described 3D scale is provided with white thermoprint or little dermatoglyph structure.
The utility model is compared with prior art, and its effect is actively with obvious.The utility model adopts independently light pipe structure to provide illumination separately to 3D scale in the light guide structure for auto meter 3D scale, achieves the requirement of the independent backlight of 3D scale; By controlling the size of minimal incision *, and the form of bottom surface thermoprint or thin dermatoglyph achieves the excellent homogeneity of light.

Detailed description of the invention:
Embodiment 1:
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, light guide structure for auto meter 3D scale of the present utility model, this auto meter comprises pointer 1, scale case ring 2, dial plate 4, lamp-box frame 5 and pcb board 6, described dial plate 4 excircle is provided with dial scale 40, 3D scale 32 is also provided with at described dial plate 4 excircle, wherein, 3D scale light pipe 3 is also provided with in described instrument, described overall more than half annulus of 3D scale light pipe 3, 3D scale 32 is located on described 3D scale light pipe 3, 3D scale light pipe 3 is corresponding at circumferencial direction with described 3D scale 32, the below at described 3D scale light pipe two ends is respectively equipped with a LED 7 and 8, otch 31 is provided with at 3D scale light pipe 3 and described 3D scale 32 correspondence position.The length that 3D scale light pipe circumferentially extends is determined with distribution by the quantity of 3D scale, and the circumferential angle of this 3D scale light pipe is at about 300 degree usually.
Further, described 3D scale light pipe 3 is made up of the light pipe of circular in cross-section or ellipse.
Further, described otch is positioned at the lateral surface of described 3D scale light pipe, and described 3D scale is positioned at the medial surface of 3D scale light pipe.
Further, described otch is formed by two facets are crossing, the axes normal of these two faceted intersection lines and described 3D scale light pipe.
Further, the bottom surface of described 3D scale is provided with white thermoprint or little dermatoglyph structure.
As shown in Figure 3,7 and 8 is LED, and 3 is 3D scale light pipe, and 9 is index path, and the light of LED is conducted in total by light pipe 3.
As shown in Figure 4,10 is chief ray, and 3 is light pipe, and when chief ray 10 runs into minimal incision * 31, the direction of light changes, and produces time light 11, thus illuminates 3D scale 32.
As shown in Figure 5,3D high range bottom surface adopts white thermoprint or thin dermatoglyph, can allow the good scattering of light, thus obtains the homogeneity of good light.
