Description

Technical Field

[0001] The utility model relates to the field of vehicle lamp modules, and more specifically, to an outer lens support structure of a focal length adjustable vehicle lamp module. Background Art

[0002] Adaptive Driving Beam (ADB) is an intelligent anti-glare high beam system. When targets such as vehicles and pedestrians appear on the road surface, a control system composed of sensors and drive circuits will automatically adjust the high beam illumination area, so as to avoid dazzling the illuminated targets, and at the same time ensure clear high beam illumination during driving. The ADB module has the advantages of good light pattern uniformity, fewer module numbers, and beautiful appearance in the application of vehicle lamp assemblies. With the update of LED technology, the complexity of the ADB module is also continuously increasing.

[0003] With the development of vehicle lamp technology, the application of imaging optics in vehicle lamps is becoming more and more extensive. In order to ensure that the imaging degree of each module meets the design requirements (or the near light part meets the regulation sharpness requirements), a support system that can adjust the distance between the outer lens and the light source is very necessary. At present, there is a lack of a lens support system that can support the focusing of the outer lens, and the outer lens support only plays a fixing role.

[0004] The existing patent authorization publication number: CN221324226U, discloses an adaptive high beam lamp, including a heat dissipation component, a light source component, an inner lens component and an outer lens component. The heat dissipation component includes a mounting substrate and a plurality of heat dissipation fins. The mounting substrate includes a first side surface and a second side surface arranged opposite to each other. The heat dissipation fins are arranged on the first side surface, and the heat dissipation fins are radially distributed; the light source component is fixedly arranged on the second side surface, and the light source component includes a plurality of lamp beads; the inner lens component is fixedly arranged on the side of the light source component away from the heat dissipation component; the inner lens component includes a plurality of inner lenses, and the inner lenses are arranged in one-to-one correspondence with the lamp beads; the outer lens component is fixedly arranged on the second side surface and covers the light source component and the inner lens component; the outer lens component includes an outer lens, and the projection of the outer lens towards the second side surface covers the inner lens. Through the above solution, the heat dissipation effect of the high beam lamp can be improved, the service life can be increased, and the production process cost is relatively low.

[0005] However, the existing technology has the following problems: the lens support can only fix the outer lens, and cannot change the front and rear position of the outer lens within a certain range, cannot achieve precise focusing of products with different specifications, and cannot conveniently adjust the imaging effect; at the same time, if the existing technology wants to modify the distance between the outer lens and the light source, it needs to modify the mold, which brings disadvantages such as high cost and long cycle. Summary of the Utility Model

[0006] Therefore, to solve the above technical problems, the present utility model proposes an outer lens support structure for a focal length adjustable headlight module, which includes an outer lens 10 and a lens support 20 connected to the outer lens 10.

[0010] Further, a damping ring 60 is provided on the outer wall of the fixed base 202.

[0012] Further, the damping ring 60 is made of rubber, which is easy to deform, has a good frictional force effect and is durable.

An air flow channel is formed between adjacent heat dissipation fins 402, so that heat can be dissipated through the air flow channel. The radiator 40 is connected to the lens bracket 20 through a locking screw 100.

[0014] Further, the other side of the mounting substrate 401 is connected to the core optical component 30 by means of a thermal adhesive, screws or riveting.
