Description

TECHNICAL FIELD

[0001] The utility model relates to light guide plate technical field, especially a light guide plate for instrument panel. BACKGROUND

[0002] The automobile instrument panel is the device reflecting the working condition of each system of the vehicle.

[0003] On the mechanical instrument panel, the speed is indicated by the pointer, and the information of the vehicle driving is indicated by the indicator light. The light guide plate is usually used on the instrument panel to uniformly distribute the light, but the current instrument panel needs to display more information, and part of the information is arranged in the rotation range of the pointer of the instrument panel. The traditional uniformly distributed light cannot highlight the display of the specific position, so that the driver cannot quickly capture the required information at night, affecting the driving safety. SUMMARY

[0004] The utility model discloses a light guide plate for instrument panel.

[0005] The utility model discloses a light guide plate for instrument panel, including the board body, the board body includes upper layer and lower layer, a plurality of light guide pipes are arranged to the lower layer, the lower end of light guide pipe is smoothly provided with the expansion part, the upper layer is provided with the half circle empty space in the connecting position of light guide pipe.

[0006] Further setting is that the lower surface of expansion part is the concave structure of arc.

[0007] Further setting is that the light transmittance of lower layer is 70%, and the light transmittance of upper layer is 90%.

[0008] Further setting is that the lower layer is provided with annular edge.

[0009] Further setting is that the inner edge of annular edge is provided with the reflection coating.

[0010] In summary, the utility model has the following beneficial effects: by adopting the upper and lower layer setting, and setting the light guide pipe in the lower layer, the light can be displayed in a certain range of the upper layer through the guide pipe, so that the amount is increased in the position that needs to be highlighted, and the driver can quickly capture the information of the position. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 It is cross section schematic view of light guide plate.

[0012] In the figure: 1, plate body; 2, upper layer; 3, lower layer; 4, light guide pipe; 5, expansion part; 6, empty space; 7, arc-shaped concave structure; 8, ring-shaped edge; 9, reflective coating. DETAILED DESCRIPTION

[0013] The utility model will be explained in further detail below in combination with the drawings.

[0014] A light guide plate for instrument panel, comprising a plate body 1, the plate body 1 includes upper layer 2 and lower layer 3.The light transmittance of lower layer 3 is 70%, and the light transmittance of upper layer 2 is 90%.

[0015] A plurality of light guide pipes 4 are vertically arranged on the lower layer 3, and the positions of the light guide pipes 4 are set according to actual needs, such as being arranged below the icons to be displayed or below the prong protrusions (indicating speed).

[0016] The light guide pipe 4 is made of the material of the inner core of a light guide fiber, and can have better light transmission performance. The lower end of the light guide pipe 4 is smoothly provided with an expansion part 5, the expansion part 5 expands outward in the downward direction, and the bottom thereof is flush with the lower surface of the lower layer 3. At the same time, the lower surface of the expansion part 5 is provided with an arc-shaped concave structure 7. When the LED lamp at the bottom of the instrument panel is on, light can enter the light guide pipe 4 from the arc-shaped concave structure 7 and be transmitted upward through the light guide pipe 4.

[0017] The upper layer 2 is provided with a semicircular empty space 6 at the connecting position with the light guide pipe 4, and light entering the empty space 6 from the light guide pipe 4 is scattered and enters the upper layer 2. Due to the semicircular structure of the empty space 6, a small part of the light will be concentrated in the middle position, but at the same time, it will also be scattered to the periphery, achieving the effect of brighter in the middle, so as to highlight the display of icons or prong protrusions.

[0018] The lower layer 3 is provided with a ring-shaped edge 8, and the inner edge of the ring-shaped edge 8 is provided with a reflective coating 9. Preferably, the edge of the lower layer 3 has two upper and lower chamfers, and the inner edge of the ring-shaped edge 8 is attached to the chamfers.

[0019] The specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, but as long as the modifications are within the scope of the claims of the utility model, they are protected by the patent law.
