Description

Technical Field

[0001] The utility model relates to the field of light guide plates, in particular to a light guide plate used in a vehicle, and an installation structure of the light guide plate and a light-increasing component. Background Art

[0002] The light guide plate is made of optical-grade acrylic / PC sheet, and then uses high-tech materials with extremely high refractive index and non-light absorption. The light guide points are printed on the bottom of the optical-grade acrylic sheet using laser engraving, V-shaped cross grid engraving, and UV screen printing technology. The optical-grade acrylic sheet is used to absorb the light emitted from the lamp and stay on the surface of the optical-grade acrylic sheet. When the light hits each light guide point, the reflected light will diffuse to all angles, and then destroy the reflection conditions and be emitted from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can emit light evenly.

[0003] In the prior art, the light guide plate is provided with a positioning protrusion for positioning the light-increasing component. The light-increasing component is stacked on the light guide plate through the positioning protrusion. The setting of the positioning protrusion prevents the light-increasing component from moving arbitrarily on the light guide plate, thereby avoiding affecting the normal display of the display screen. However, the front end of the light guide plate only partially rests on the light bar. When the light guide plate expands thermally, the light guide plate squeezes part of the light bar, which can easily cause the light bar to deform and affect the service life of the light source.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content

At the same time, a soft pad is provided at the upper end of the reinforcing protrusion and the abutting surface, so that the light guide plate is in contact with the light bar through the soft pad, further reducing damage to the light bar, and the lower end of the reinforcing protrusion extends downward beyond the lower wall surface of the first avoidance groove, and the reinforcing protrusion can also play a positioning role for positioning the light-enhancing component.
