Preferably, the circumference of the thick-walled light guide mounting plate 145 extends away from the first light guide bar 110 and the second light guide bar 120 to form a side plate, which is located, for example, above, below, left and/or right of the light guide bracket 170, so as to limit the first light guide bar 110 and the second light guide bar 120 in a direction perpendicular to the light exiting direction, avoiding the positional shift of the first light guide teeth 111 and the second light guide teeth 121, resulting in that the first light guide teeth 111 and the second light guide teeth 121 cannot accurately enter the first thick-walled light guide 141 and the second thick-walled light guide 142.
In a specific embodiment, the light guide support 170 includes a light guide support 170 body and mating plates disposed on two sides of the light guide support 170 body, where the mating plates are used to engage with the side plates, so that the light guide support 170 is more firm.
Preferably, the mating plate is a folded plate, and the mating plate extends toward the side plate and further extends away from the thick-wall light guide opening 162, so that when the light guide bracket 170 is mated with the thick-wall light guide mounting plate 145, the mating plate can be pushed inward to deform the mating plate, thereby disassembling the light guide bracket 170 in the direction.
The present application provides a vehicle (not shown) comprising a shaped lamp light guide assembly 100 as any one of the above. It should be noted that, by providing the light guide assembly 100 for a shaped lamp, the vehicle can achieve one or more of the above technical effects.
Although the present application is disclosed above, the present application is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the application, and the scope of the application should be assessed accordingly to that of the appended claims.
