Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a heat dissipation structure for a shared integrated heat sink for multi-functional taillights in automobiles. Background Technology

[0002] Existing technologies have adopted various technical measures to solve the problem of heat dissipation in vehicle lights:

[0003] In the Chinese utility model patent (publication number CN216047538U, patent title: A high-efficiency heat conduction radiator for LED automotive lamp module), when the shaft rotates, the screw cap and push rod can push the slide plate and horizontal plate to reciprocate left and right. During the reciprocating movement of the horizontal plate, the gear and the vertical plate fixed by the support rod first rotate counterclockwise and then clockwise. The oscillation of the vertical plate accelerates the flow of hot air inside the lamp cover, achieving better heat dissipation. This design overcomes the shortcomings of existing LED automotive lamp module radiators, which mostly rely on fans and heat conduction for heat dissipation inside the lamp cover, resulting in slow heat dissipation and insufficient heat dissipation. Furthermore, this design makes the automotive lamp structure more complex.

[0004] In the Chinese utility model patent (publication number CN222256212U, patent title: A Direct-Plug-in Integrated High-Power Heat Dissipation Vehicle Light), when the light panel is energized to emit light, the panel simultaneously powers an electric fan via a connecting piece. This causes the electric fan to rotate and blow air, dissipating the internal heat through multiple heat dissipation holes and exhaust vents. This rapidly dissipates heat from the integrated light body, preventing overheating and damage, and ensuring the light's lifespan. This design overcomes the problem of poor heat dissipation in direct-plug-in vehicle lights caused by rapid heat accumulation due to high power output. Furthermore, using a fan would make the light structure more complex and increase costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a heat dissipation structure for a shared integrated heat sink for multi-functional taillights in automobiles, thereby solving the problem.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A heat dissipation structure for a shared integrated heat sink for a multi-functional taillight of an automobile includes a lamp housing, a PCB board, an LED lamp, and a heat sink. The heat sink is characterized in that the heat sink is an integrated structure, a heat sink is fixed inside the lamp housing, and the PCB boards on which the brake lights, position lights, rear fog lights, turn signals, and reversing lights of the multi-functional taillight are mounted are all fixed on the heat sink.

[0008] The heat sink is made of aluminum.

[0009] This utility model relates to a heat dissipation structure for a shared integrated heat sink for multi-functional taillights in automobiles. The design is scientific, the structure is simple and compact, which is conducive to the unified planning and overall consideration of the layout of the PCB boards of various functional lights in the taillight. It is easy to install and use, and its operation is safe and reliable. It allows the working LED PCB board to be cooled by a heat sink with a relatively large heat dissipation area, which not only solves the problem of insufficient space in the taillight and the inability to make the heat dissipation structure large, but also improves the heat dissipation efficiency and reduces the heat dissipation cost.

[0013] Taillights play a crucial role in transmitting multiple functional signals at the rear of a vehicle, typically including brake lights, position lights, rear fog lights, turn signals, and reversing lights. Each of these taillight functions generally requires a separate LED PCB board and heat sink. However, the limited space of the taillight's overall structure restricts the arrangement of these LED PCB boards and heat sinks. This invention addresses this specific situation by adopting a heat dissipation structure where the PCB boards for each taillight function share a common heat sink. This approach facilitates unified planning and a more rational layout of the PCB boards for each function. Furthermore, while the shared heat sink is relatively large and occupies limited taillight space, the LEDs for each function typically do not operate simultaneously. This allows the active LED PCB board to utilize the relatively large heat sink area for cooling, maximizing heat dissipation and enhancing overall cooling efficiency. Figure 1 As shown, the present invention relates to a heat dissipation structure for a shared integrated heat sink for a multi-functional taillight of an automobile, comprising a lamp housing, a PCB board 1, an LED lamp 2, and a heat sink 3. In this embodiment, the heat sink 3 is an integrated aluminum heat sink. A heat sink 3 is fixed inside the lamp housing. The brake light, position light, rear fog light, turn signal, and reversing light of the multi-functional taillight, each of which has an LED lamp 2 mounted on a PCB board 1, are all fixed on the heat sink 3.

[0014] This invention relates to a common aluminum heat sink for LED light panels with different functions, which quickly dissipates heat through thermal conduction. This solution is suitable for situations where taillight space is limited and the rigid PCB area cannot be made large. By using a common aluminum heat sink for each functional LED light, heat dissipation costs are reduced, the problem of insufficient taillight space and the inability to make a large rigid PCB area is solved, and heat dissipation efficiency is improved.

[0015] The above description is only a general embodiment of this utility model. For those skilled in the art, there are various other embodiments with modifications and variations, which will not be elaborated here. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model are included within the protection scope claimed by this utility model.
