Description

Technical Field

[0001] The present invention relates to the field of vehicle light modules, and more specifically, to a low-beam baffle module with an integrated sunshade. Background Art

[0002] With the development of vehicle lighting technology, ADB headlights are becoming more and more common. However, due to the limitations of vehicle lighting shape and headlight space, modules with dual functions of low beam and ADB are being used in more and more vehicle models. To ensure the uniformity of the ADB light pattern and compliance with regulations, a sunshade is designed in the light entrance area of ​​the ADB inner lens to prevent light from crossing between particles and reduce stray light in the ADB light pattern.

[0003] At present, dual-function modules on the market are designed with two parts, a low-beam baffle and a shading plate, to achieve the low-beam and shading effects respectively, such as patent CN 220911204 U. The number of parts is large, and the internal lens structure is complex. It is necessary to design the installation and positioning structures of the low-beam baffle and the shading plate separately. In addition, the existing solutions are more complicated to assemble and have a long production cycle.

[0004] Therefore, a low-beam baffle module with an integrated sunshade is needed. Summary of the invention

[0005] In view of this, in order to solve the above problems, the present invention proposes a low-beam baffle module with an integrated sunshade, which reduces the number of parts of the product, simplifies the assembly process of the ADB lens, shortens the production cycle of the entire module, saves working hours, improves the utilization rate of light, has better heat dissipation, and increases the service life.
