Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle lamp reflectors, and more specifically, relates to a reflective device for an integrated vehicle lamp. Background Art

[0002] Light reflectors are widely used in optical lighting, signal indication and other devices, such as vehicle lamps of motor vehicles. With the progress of technology and the diversification of consumer demands, the functions required by vehicle lamps are becoming more and more abundant. For example, high beam lamps, low beam lamps, position lamps, daytime running lamps, turn signals, brake lamps, etc. In the current vehicle lamp modules of motor vehicles, the light reflectors for realizing the above various function lamps are independently arranged, thus occupying independent spaces respectively. And for the light reflectors to realize different functions, different requirements may be imposed on the positions of different light sources. Once the reflection angle is small, its warning property will be seriously affected. Therefore, there is an urgent need to study an integrated reflective device for vehicle lamps with a wide application range and strong applicability. Summary of the Utility Model

[0003] In view of this, the technical problem to be solved by the utility model is to provide a reflective device for an integrated vehicle lamp, so as to avoid the trouble of the conventional vehicle lamp reflectors being independently arranged, having a single structure and a low reflection angle.

[0004] To solve the above technical problem, the utility model discloses a reflective device for an integrated vehicle lamp, which comprises:

[0005] A reflective housing having spaced upper and lower lamp cavities, and lamp holes are respectively provided at the centers of the upper and lower lamp cavities. The lower lamp cavity is composed of an inner concave bowl surface surrounding the lamp hole and reflection planes respectively arranged around the inner concave bowl surface and extending forward;

[0006] Strip-shaped light guiding edges arranged on the inner wall of the upper lamp cavity and distributed horizontally;

[0007] A plurality of quadrilateral light guiding blocks arranged on the inner concave bowl surface;

[0008] Multiple groups of enhanced reflection units arranged on the reflection planes.

[0009] According to an embodiment of the utility model, the strip-shaped light guiding edges are convex in arc and have a width of 1.5 - 2.5 mm.

[0010] According to an embodiment of the utility model, the enhanced reflection units are arranged as a plurality of connected semi-circular linear light guiding edges with a width of 1 mm.

[0011] According to an embodiment of the utility model, mounting stud holes are provided around the reflective housing.

[0012] According to an embodiment of the present utility model, a step is provided at the edge of the lamp hole.

[0013] Compared with the prior art, the present utility model can achieve the following technical effects:

[0014] By integrating the upper lamp cavity and the lower lamp cavity into the reflective housing to form two lamp cavities, the adaptability is improved. At the same time, strip-shaped light guide ribs are arranged on the inner wall of the upper lamp cavity, which is suitable for light sources with lower functions such as width indication lights. Quadrilateral light guide blocks and enhanced reflection units are respectively arranged in the lower lamp cavity, which is suitable for light sources with strong warning functions of fog lights, thereby increasing the reflection angle and further enhancing the warning effect.

[0015] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned technical effects simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Among them, the lower lamp cavity 12 has a relatively large space and is composed of an inner concave bowl surface 20 and a reflection plane 30. The upper lamp cavity 11 has a relatively small space, and strip-shaped light guide ribs 40 are arranged on the inner wall to realize the reflective light guide of the light source installed in the middle lamp hole, and a width indicator lamp can be installed. A quadrilateral light guide block 50 is arranged on the inner concave bowl surface 20 of the lower lamp cavity 12 to realize large-angle reflection, improve warning performance, and a fog lamp can be installed. In addition, multiple groups of enhanced reflection units 60 are also installed at the reflection plane 30 to further increase the reflection angle, increase the emission range, and improve the warning performance.
