Description

Technical Field

[0001] The utility model relates to the field of automotive lamps, and particularly to an automotive lamp with adjustable distance. Background Technique

[0002] Automotive lamps are installed on automobiles and are devices that provide lighting and signal indication for vehicles when driving at night, in rainy and foggy weather, and other low visibility conditions. The headlamps of automobiles, also known as headlights, are mainly used to illuminate the road ahead of the vehicle to ensure that the driver can clearly see the road conditions ahead at night or under low visibility conditions. Currently, automotive lamps are often fixedly installed on the exterior of automobiles through bolts. Due to the different heights of different automobiles, the lighting distance of automotive lamps is limited. Therefore, an automotive lamp with adjustable distance is needed.

[0003] A patent document with the prior art publication number CN206682798U provides an automotive headlamp, including: a light-emitting component, a reflector cup, and a lens component. Among them, the light path starts from the light source of the light-emitting component, is reflected by the reflector cup, transmitted to the lens component, and diverges outward by the lens component. The automotive headlamp provided by the utility model sets the light source of the light-emitting component and the focal point of the lens component in different horizontal planes, thereby making full use of the lens component, increasing the light flux entering the lens component, and further improving the brightness range of the headlamp. In addition, the light passes through the reflector cup and the lens component, thereby reducing the light temperature and further reducing the temperature of the headlamp, and prolonging the service life of the headlamp. However, when the technology of CN206682798U is in operation, the lamp is fixedly installed in the automobile, which is inconvenient to adjust the installation irradiation distance of the automotive lamp according to the actual use requirements, and it is also inconvenient to disassemble and replace the worn lamp protective cover, thereby affecting the light transmittance of the protective cover. Therefore, an automotive lamp with adjustable distance is urgently needed. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an automotive lamp with adjustable distance to solve the problems that the existing automotive lamps are inconvenient to adjust the installation irradiation distance according to the actual use requirements and are inconvenient to disassemble and replace the worn lamp protective cover.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an automotive lamp with adjustable distance, including a fixed frame. Threaded holes are opened inside the fixed frame, bolts are movably connected inside the threaded holes, a lamp housing is movably connected inside the fixed frame, convex plates are fixedly connected to the outer wall of the lamp housing, limiting holes are opened inside the lamp housing, snap rings are fixedly connected to the outer wall of the lamp housing, and a light bulb is installed inside the lamp housing.

[0006] A threaded groove is provided inside the lamp housing, and a threaded insertion ring is movably connected to the inner wall of the lamp housing. A protective cover is fixedly connected to the outer wall of the threaded insertion ring, and a light-transmitting plate is fixedly connected to the outer wall of the protective cover.

[0007] A polyethylene terephthalate film is fixedly connected to the outer wall of the light-transmitting plate, and a thermoplastic polyurethane film is installed inside the polyethylene terephthalate film.

[0008] Preferably, the bolt is threadedly connected to the fixed frame through the threaded hole, and the bolt is adapted to the threaded hole.

[0009] Preferably, the bolt is snap-fitted to the lamp housing through the limiting hole, and the limiting holes are arranged at equal intervals on the outer wall of the lamp housing.

[0010] Preferably, the fixed frame is of a slotted design, and the fixed frame forms a sliding structure with the lamp housing through the convex plate.

[0011] Preferably, the lamp housing is threadedly connected to the threaded insertion ring through the threaded groove, and the light-transmitting plate is inlaid on one side of the inner wall of the protective cover.

[0012] Preferably, the polyethylene terephthalate film is adhesively connected to the light-transmitting plate, and the polyethylene terephthalate film and the thermoplastic polyurethane film are closely attached to each other.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By setting the fixed frame, bolt, lamp housing, limiting hole and bulb, when pulling the lamp housing, the lamp housing can be driven to slide along the inner wall of the fixed frame. When the bulb extends to the required distance, rotating the bolt can make the bolt insert into the corresponding limiting hole for limiting, which is convenient for adjusting the installation irradiation distance of the automotive lamp according to the actual use requirements, thereby improving the irradiation range and distance of the automotive lamp;

[0015] 2. By setting the threaded groove, threaded insertion ring and protective cover, rotating the protective cover can make the threaded insertion ring rotate and the threaded insertion ring can be removed from the threaded groove, which is convenient for disassembling and replacing the worn protective cover and improves the convenience of overhauling the automotive lamp;

[0016] 3. By setting the light-transmitting plate, polyethylene terephthalate film and thermoplastic polyurethane film, fixedly connecting the polyethylene terephthalate film to the outer wall of the light-transmitting plate can improve the waterproof and anti-fog performance of the light-transmitting plate. Since the thermoplastic polyurethane film is fixedly connected to the outer wall of the polyethylene terephthalate film, the wear resistance of the light-transmitting plate can be improved, thereby increasing the service life of the light-transmitting plate.
