Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, specifically to a detachable radiator automotive taillight. Background Technology

[0002] Currently, automotive lights all use LED light sources, which have advantages such as energy saving, small size, fast response speed, and long lifespan. However, as the power of LEDs increases, the heat generated also increases. If this heat cannot be effectively dissipated, it will lead to a shortened LED lifespan and reduced luminous efficiency. Therefore, heat sinks need to be added to the light fixtures.

[0003] Most commercially available rear fog lights and other lighting fixtures have their radiators installed on the sides of the base housing, resulting in excessive thickness and other dimensions that make them inconvenient to install inside the vehicle. The radiators are also easy to remove, so improvements are needed. Utility Model Content

[0004] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0005] This application discloses a detachable radiator automotive taillight, including a radiator for heat conduction, a base, and a light distribution lens. The light distribution lens is provided at the light outlet formed at the first end of the base. The bottom end of the base is provided with an installation port for installing internal components, and a radiator for heat conduction is provided at the installation port to seal the installation port. The radiator is provided with a wiring hole for wire harness passage.

[0006] This solution changes the installation position of the radiator, blocking the mounting port at the rear end of the bottom housing with the radiator, which helps to reduce the thickness of the lamp and the space required for the lamp to be installed on the vehicle body. The radiator configuration at the rear end of the bottom housing also facilitates the removal and installation of the radiator. The wiring holes on the radiator facilitate the electrical connection of various components inside the bottom housing.

[0007] Furthermore, the radiator includes a plate-shaped body, with a plurality of protrusions spaced apart on the end face of the body facing away from the bottom shell, and wiring holes provided on the body near the side protrusions. The spaced protrusions help to improve the heat dissipation effect, and the wiring holes formed on the side of the area where the protrusions are located help to reduce the molding difficulty.

[0008] Furthermore, a protrusion is provided on the end face of the main body facing the mounting port. The protrusion is embedded in the mounting port, and the end face of the main body surrounding the protrusion abuts against the end face of the mounting port, thereby improving the stability of the radiator installation.

[0009] Furthermore, positioning holes are provided on both sides of the main body and a positioning post is provided at the corresponding tail end of the bottom shell. The positioning post extends into the positioning hole, and the heat sink is pre-fixed to the bottom shell by the insertion of the positioning post and the positioning hole, which facilitates subsequent fixing operations.

[0010] Furthermore, the main body is provided with mounting holes and a fixing post is provided at the tail end of the bottom shell. The fixing post is provided with a fastening hole corresponding to the position of the mounting hole. For example, a screw can be passed through the mounting hole and screwed into the fastening hole to improve the stability of the installation.

[0011] Furthermore, the end face of the main body has a protruding wiring hole, which serves to protect the wire.

[0012] Furthermore, a fixing post two is provided at the tail end of the bottom shell on one side of the mounting port, and a fastening hole two is provided axially at the end face of the fixing post two. The rear bumper brush of the car is screwed into the fastening hole two to fix the bottom shell and the rear bumper, which facilitates installation.

[0013] Furthermore, it also includes a second light distribution lens, wherein the first light distribution lens is located at the groove formed in the middle of the second light distribution lens. If the first and second light distribution lenses are different colors, the two-tone color scheme helps to improve the aesthetics.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figures 1-5 As shown, in this example, a detachable radiator automotive taillight includes a radiator 2 for heat conduction, a base shell 1, and a light-distributing lens 3. The base shell 1 is flat and cylindrical, with a light outlet formed at its front end. The light-distributing lens 3 is installed at the light outlet and is fixed to the light outlet by vibration friction welding. A second light-distributing lens 4 can also be added, such as the light-distributing lens 3 located at a groove formed in the middle of the second light-distributing lens 4. The first and second light-distributing lenses form a two-tone design, which is more aesthetically pleasing. The second light-distributing lens is also fixed to the end face of the base shell at the light outlet by vibration friction welding.

[0027] In this example, the rear end of the bottom shell 1 is formed with a mounting port 10 for installing internal components. For example, a lamp panel or other components are installed into the cavity of the bottom shell 1 through the mounting port 10. A heat sink 2 for heat conduction is placed at the mounting port 10, and the mounting port is sealed by the heat sink. Wiring holes 23 for wire harnesses are formed on the heat sink 2. The heat sink may include a plate-shaped body 21 with several protruding pillars 22 at intervals on the end face of the body 21 facing away from the bottom shell 1. Wiring holes 23 are formed along the thickness direction on the end face of the body 21 adjacent to the side protruding pillars. The protruding pillars improve heat dissipation, and wires and wire harnesses that connect to the components inside the bottom shell cavity can pass through the wiring holes and connect to the corresponding mechanisms on the vehicle body. This configuration reduces the thickness and other dimensions of the lamp, helping to reduce the lamp's volume and facilitating installation on the vehicle body. The structure that fixes the heat sink at the rear end also facilitates the installation or removal of the heat sink.

[0028] To facilitate radiator installation, positioning holes 24 are formed along the thickness direction on both sides of the main body 21, and a positioning post 13 is formed at the tail end of the corresponding bottom shell 1. During installation, the positioning post 13 extends into the positioning hole 24 of the radiator 2 to pre-fix the radiator. Mounting holes 25 can also be added to the main body 21, such as mounting holes 25 formed along the thickness direction at both ends of the main body 21, and a fixing post 14 corresponding to the tail end of the bottom shell 1. A fastening hole 15 is formed axially at the position of the fixing post 14 corresponding to the mounting hole. During installation, screws are passed through the mounting hole and screwed into the fastening hole 15, improving installation stability.

[0029] To improve the installation stability of the radiator, a plate-shaped protrusion 26 can be formed outward at the middle of the end face of the main body 21 facing the mounting port 10. The protrusion 26 is embedded in the mounting port 10, and the end face of the main body 21 surrounding the protrusion 26 abuts against the end face of the mounting port 10. Figure 5 As shown.

[0030] This light fixture is installed and fixed at point 5 on the rear bumper of the vehicle. Figure 4 , Figure 5 As shown, a fixing post 2 11 can also be formed at the tail end of the bottom shell 1 on one side of the mounting port 10. A fastening hole 2 12 is formed axially at the end face of the fixing post 2 11. During installation, the bolts of the rear bumper of the car are screwed into the fastening hole 2 to fix the bottom shell and the rear bumper.

[0031] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope.
