Light guide fixing assembly for vehicle lamp, vehicle lamp and vehicle

Abstract

The invention relates to a light guide fixing assembly for a vehicle lamp, the vehicle lamp and a vehicle. The light guide fixing assembly comprises a main lining frame (1), a light guide (2) and a front lining frame (3), a light guide containing groove (7) is formed in the main lining frame (1), and the light guide (2) is mounted on the light guide containing groove (7) and comprises a first ribpart (21) and a second rib part (22) which extend on the whole length of the light guide (2) and radially relatively protrude out. The front lining frame (3) is fixed to the main lining frame (1) andcovers the partial outer surface of the light guide (2), a first gap (4) and a second gap (5) are formed between the main lining frame (1) and the front lining frame (3), and the first rib part (21) and the second rib part (22) of the light guide (2) are clamped into the first gap (4) and the second gap (5) correspondingly. According to the light guide fixing assembly, when the light guide (2) isturned on, light emitting uniformity can be kept on the whole length of the light guide (2), and the part material cost and the man-hour cost in the assembly process are reduced.

Description

technical field [0001] The present invention generally relates to the field of vehicle components, and more specifically, relates to a light guide fixing assembly for vehicle lights (especially headlights). The invention also relates to a vehicle light comprising such a light guide fixing assembly, and to a vehicle comprising such a light guide. Background technique [0002] With the development of automobile technology, the requirements for the luminous effect of vehicle lights (especially headlights, including low beams and high beams) are also getting higher and higher. Current vehicle lamps are usually equipped with a light guide. However, considering the uniformity of light emission when the light guide is lit, there are high requirements for the way the light guide is fixed on the lamp. [0003] Figure 1 to Figure 3 A schematic diagram of a light guide fixing assembly used in a vehicle lamp in the prior art is schematically shown, and the light guide 2 is fixed on th...

Problems solved by technology

[0004] However, especially for larger-sized vehicle headlights, the length of the light guide of the headlight is relatively large, for example, it can be close to about 600mm, and the method of fixing both ends usually cannot meet the assembly and vibration requirements of the headlight

Moreover, the non-uniformity of the component structure due to the existence of multiple local fixed fulcrums may lead to uneven luminous brightness when the light guide is lit, especially bright spots will be generated at the fulcrum position, thereby affecting the luminous effect

In addition, due to the need to set multiple connecting plates on the light guide and the corresponding connecting parts on the main lining frame, the local fixing structure is relatively complicated, which increases the man-hour cost during the assembly process, and the existence of multiple screws also increases the part cost.
