Description

Technical Field

[0001] The utility model relates to the field of vehicle lamp light guide plates, in particular to a vehicle lamp light guide plate which can be overlapped in plurality and is convenient to replace. Background Art

[0002] The light guide plate is made of optical-grade acrylic / PC sheet, and then made of 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 spread to all angles, and then destroy the reflection conditions and emit from the front of the light guide plate.

[0003] Chinese patent publication number CN216595599U discloses an improved light guide plate, comprising a first light guide plate and a second light guide plate, each of which is provided with a snap-on assembly, the snap-on assembly comprising a slide groove formed on the front surface of the first light guide plate, a threaded rod located inside the first light guide plate being movably connected to the interior of the slide groove, a movable rod located inside the first light guide plate being fixedly connected to the bottom end of the threaded rod, a snap-on plate being fixedly connected to the rear surface of each end of the movable rod, and a support seat movably connected to the snap-on plate being fixedly connected to the rear surface of the inner cavity of the first light guide plate. The improved light guide plate, by providing the snap-on assembly, allows the user to align the snap-on plate on the first light guide plate with the snap-on hole on the second light guide plate when installing and removing the light guide plate, so that the snap-on plate is firmly connected by magnetic attraction. When removing the light guide plate, the snap-on plate is driven to slide on the support seat and detach from the iron plate by sliding down the threaded rod, thereby achieving the effect of quick removal and installation.

[0004] The light guide plate of the headlight of the above patent is usually installed on the car as a single piece. When the light guide plate is damaged and cannot work normally and needs to be replaced, it is necessary to remove the damaged light guide plate and install a new one, which is a relatively complicated process. Utility Model Content

[0005] The purpose of the present utility model is to provide a vehicle lamp light guide plate that is easy to replace by overlapping multiple light guide plates. A strip slide is provided on the light guide plate, and a slider is provided at the lower end of the light guide plate; and a limit groove is provided in the light guide plate, a limit rod is provided in the limit groove, and a pull ring is provided at one end of the limit rod. When the light guide plate is installed on the car, multiple light guide plates can be overlapped by inserting the strip slide into the strip slide provided on the lower light guide plate. When the top light guide plate is damaged, it is only necessary to pull the pull ring to pull out the damaged light guide plate, and the undamaged light guide plate on the lower layer can continue to work normally, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a vehicle lamp light guide plate that is easily replaced by being overlapped in multiple ways, comprising a light guide plate body, a limiting groove being provided in the light guide plate body, a limiting rod being provided in the limiting groove, and a limiting block being provided, the limiting block being provided at one end of the limiting rod, a rotating bearing being provided at the end of the limiting rod away from the limiting block, a slide rail being provided at the upper end of the light guide plate body, and a slider being provided at the lower end of the light guide plate body.

[0007] Preferably, the rotary bearing is provided with a connecting rod at one end away from the limiting rod, and the connecting rod is movably connected to the rotary bearing.

[0008] Preferably, the connecting rod is provided with a connecting block at one end away from the rotary bearing, and the connecting block and the connecting rod are provided as one piece.

[0009] Preferably, the connecting block is provided with a pull ring at one end away from the connecting rod, and the pull ring is integrally provided with the connecting block.

[0010] Preferably, the slide rail and the slider are both provided with a first reserved bolt hole.

[0011] Preferably, a fixing block is provided on the light guide plate body, and the fixing block and the light guide plate body are integrally provided.

[0012] Preferably, a second reserved bolt hole is provided on the fixing block, and the second reserved bolt hole is integrally provided with the fixing block.

[0013] Preferably, a magnet adsorption groove is provided on the outer surface of the slide rail, and the magnet adsorption groove and the slide rail are integrally provided.

[0014] Preferably, the slider is provided with a magnet at a position corresponding to the magnet adsorption groove, and the magnet is adhesively connected to the slider.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] According to the utility model, before installing the light guide plate body on the car, the user first stacks several light guide plate bodies up and down. When the uppermost light guide plate body is damaged, the user only needs to pull the pull ring to drive the limit rod to move in the limit groove until the limit block provided on the limit rod abuts against the inner wall of the limit groove, so that the limit rod can no longer be withdrawn. Then the light guide plate body will be pulled out by the force applied to the pull ring, and the damaged light guide plate body will be pulled out, and the lower undamaged light guide plate body can continue to work normally. Moreover, since the limit rod and the limit block are made of the same material as the light guide plate body, the light transmittance of the light guide plate body will not be affected, which effectively avoids the problem that the existing headlight light guide plate is usually installed on the car as a single piece. When the light guide plate is damaged and cannot work normally and needs to be replaced, the damaged light guide plate needs to be disassembled and a new light guide plate needs to be installed, which is a relatively complicated process.
