Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and in particular relates to a heat dissipation type automobile lampshade. Background Art

[0002] Car lights are essential components of a vehicle, encompassing both the lamp and the bulb. One function of the lamp is to focus and re-emit the light emitted by the bulb, thereby enhancing its brightness and range. Car lights typically include turn signals, brake lights, rear fog lights, and backup lights. These lights are positioned in different locations within the taillight housing, requiring the light emitted by each lamp to be clearly visible through the taillight housing.

[0003] Existing halogen bulbs consume a lot of power and have a short lifespan, increasing vehicle owners' operating costs. Furthermore, the lamps operate under high voltage, posing a safety hazard. They also suffer from poor heat dissipation, shortening their lifespan, and poor sealing, which hinders dust protection. Utility Model Content

[0012] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0013] 1. By providing a first curved heat sink 11 and a second curved heat sink 12, a better heat dissipation effect can be obtained. The interior of the shell can be divided into an upper and lower part by the heat insulation plate 4. A lamp body 5 is provided in the upper shell 2. The lamp body 5 generates heat when it emits light. The heat insulation plate 4 can prevent the heat generated in the lower shell 3 from entering the upper shell 2, accelerating the increase in the temperature of the lamp body 5, and preventing the performance of the light source of the lamp body 5 from being affected by excessive temperature; the lamp body 5 can be in contact with the central column 1, and the generated heat will be transferred to the second curved heat sink 12 through the central column 1 and the first curved heat sink 11. The heat can be dissipated to the bottom of the heat insulation plate 4 through the second curved heat sink 12, and the heat can be dissipated to the outside through the heat dissipation holes 31 on the lower shell 3 to avoid temperature increase; and the heat is transferred from the first curved heat sink 11 to the second curved heat sink 12, so that the heat dissipation effect is increased, which is convenient for dissipating the heat inside the shell; the bottom surface of the first curved heat sink 11 is in contact with the top surface of the corresponding second curved heat sink 12, which is convenient for heat transfer;

[0014] 2. The upper housing 2 and connecting block 6 are sealed via a threaded structure. The annular flexible sealing strip 8 of the upper housing 2 abuts against the annular sealing flange 7 of the connecting block 6.

Furthermore, the annular flexible sealing edge 10 is also flexible and abuts against the inner wall of the sealing groove 9 even when the upper housing 2 is not tightened. This creates a dual sealing effect, enhancing sealing performance and providing excellent dustproofing. The annular flexible sealing edge 10 is slightly tilted inward of the connecting block 6 to enhance the deformation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] It should be noted that existing halogen bulbs consume relatively high amounts of electricity and have a relatively short lifespan, increasing the cost of use for car owners. Furthermore, the lamps operate under high voltage, posing a safety hazard. They also have poor heat dissipation, which shortens their service life, and poor sealing, leading to poor dustproofing. Therefore, to address the safety hazard, poor heat dissipation, and poor dustproofing associated with existing lamps, this solution incorporates first and second curved heat sinks 11 and 12, resulting in improved heat dissipation.

[0027] In this embodiment, the lamp body 5 can contact the central column 1, and the heat generated will be transferred to the second curved heat sink 12 through the central column 1 and the first curved heat sink 11. The heat can be dissipated to the bottom of the heat insulation plate 4 through the second curved heat sink 12, and the heat can be dissipated to the outside through the heat dissipation holes 31 on the lower shell 3 to avoid temperature increase.
