Description

Technical Field

[0001] This utility model relates to the field of automotive lighting accessories, and in particular to a high-efficiency heat sink structure for automotive lights. Background Technology

[0002] Car lights are crucial for road safety, playing a significant role in guiding following vehicles and pedestrians. They are especially important at night and in poor visibility conditions such as heavy fog. With the development of modern automobiles, there is an increasing demand for more specialized car lights, particularly headlights used to illuminate the road and objects in front of the vehicle.

[0003] The prior art can be referenced in Chinese authorized utility model patent CN211232755U, which specifically describes a novel LED automotive lamp heat sink, comprising a housing and antennae. The housing has detachable fasteners on both sides of its top edge, a mounting bolt hole on one side of each fastener, and a plastic retaining post on the side of each mounting bolt hole. A side plate is provided on one side wall of the housing, and a heat dissipation aluminum fin is provided intermittently at the bottom of the housing. A clip is provided on one side of the heat dissipation aluminum fin on the housing. This prior art, by setting up the housing, clips, and clips, allows the heat dissipation structure to be connected to the LED lamp in a plate-like form, reducing the space occupied by the heat dissipation structure within the lamp cover.

[0004] The aforementioned existing technology has the following shortcomings in actual implementation: installation is not very convenient, and the part connected to the car is fixed and cannot be adjusted. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a high-efficiency heat sink structure for vehicle lights, thereby resolving the issues present in the prior art.

[0006] To achieve the above objectives, the present invention provides a high-efficiency heat sink structure for automotive lights, comprising: a heat sink;

[0007] Two connecting plates are provided, respectively disposed opposite to each other at both ends of the heat sink, and the connecting plates are slidable;

[0008] One end of the connecting plate has a connecting screw hole.

[0009] Furthermore, the heat sink has receiving and releasing slots at both ends on one side, and the connecting plate is slidably arranged inside the receiving and releasing slots.

[0010] Furthermore, the inner walls on both sides of the receiving and discharging slot are provided with sliding grooves, and the connecting plate is provided with sliders on both sides, the sliders being slidably connected to the sliding grooves.

[0011] Furthermore, multiple heat dissipation columns are provided on the other side of the heat sink.

[0012] Furthermore, the heat sink has a ventilation groove inside, and a fixing pipe is provided at both ends of one side of the heat sink, and the fixing pipe is connected to the ventilation groove.

[0013] Furthermore, a movable tube is slidably disposed inside the fixed tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. When installing the heat sink, move the connecting plate out of the receiving slot so that the connecting screw holes are out of the receiving slot. Then use screws to fix the connecting plate, thereby fixing the position of the heat sink. The movable connecting plate makes it easy to adjust the position of the connecting screw holes, which makes it easy to change the connection part with the car and facilitates installation. After adjusting the position of the connecting plate, use screws to fix the position of the connecting plate.

[0016] Second, the ventilation slots allow gas to flow inside the heat sink, thereby enhancing the heat dissipation effect. During installation, one of the movable tubes is pulled out from inside the fixed tube and extended into the car's air intake position. Then, the position of the movable tube is fixed. During driving, the gas enters the interior of the fixed tube through the movable tube, and then further enters the interior of the ventilation slot. After flowing, it is discharged from the other movable tube, thus facilitating a more effective heat dissipation.

[0017] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of this utility model are now described with reference to the accompanying drawings. However, the scope of protection of this utility model is not limited to the following description.

[0025] Reference Figure 1-5 As shown, a high-efficiency heat sink structure for automotive lights includes: a heat sink 1; two connecting plates 4, which are respectively disposed opposite to the two ends of the heat sink 1 and are slidable; one end of the connecting plate 4 is provided with a connecting screw hole 5, and both ends of one side of the heat sink 1 are provided with a receiving groove 3, the connecting plate 4 is slidably arranged inside the receiving groove 3, and both sides of the receiving groove 3 are provided with sliding grooves 6, and both sides of the connecting plate 4 are provided with sliders 7, which are slidably connected to the sliding grooves 6, and multiple heat dissipation columns 2 are provided on the other side of the heat sink 1.

[0026] This utility model provides a technical solution where, in use, a heat sink 1 is installed inside a car and contacts the headlights. The heat sink 1 dissipates heat from the headlights, and the heat dissipation column 2 further enhances the heat dissipation effect. When installing the heat sink 1, the connecting plate 4 is moved out of the receiving groove 3, allowing the connecting screw hole 5 to move out of the receiving groove 3. Then, screws are used to fix the connecting plate 4, thereby fixing the position of the heat sink 1. The movable connecting plate 4 facilitates adjustment of the position of the connecting screw hole 5, thus facilitating changes to the connection point with the car and simplifying installation. After adjusting the position of the connecting plate 4, screws are used to fix its position. The provided groove 6 and the sliders 7 on both sides of the connecting plate 4 facilitate its movement.

[0027] Preferably, the heat sink 1 has a ventilation groove 8 inside, and a fixed tube 9 is provided at both ends of one side of the heat sink 1. The fixed tube 9 is connected to the ventilation groove 8, and a movable tube 10 is slidably provided inside the fixed tube 9.

[0028] Specifically, during use, the ventilation slots 8 allow gas to flow inside the heat sink 1, thereby enhancing the heat dissipation effect. During installation, one of the movable pipes 10 is pulled out from inside the fixed pipe 9 and extended into the car's air intake position. Then, the position of the movable pipe 10 is fixed. During driving, the gas enters the interior of the fixed pipe 9 through the movable pipe 10, and then further enters the interior of the ventilation slot 8. After flowing, it is discharged from the other movable pipe 10, thus facilitating a more effective heat dissipation.

[0029] Working principle: During use, the heat sink 1 is installed inside the car and contacts the headlights. The heat sink 1 dissipates heat from the headlights, and the heat dissipation column 2 further enhances the heat dissipation effect. When installing the heat sink 1, the connecting plate 4 is moved out of the receiving groove 3, allowing the connecting screw hole 5 to move out of the receiving groove 3. Then, the connecting plate 4 is fixed with screws, thus fixing the position of the heat sink 1. The movable connecting plate 4 allows for adjustment of the position of the connecting screw hole 5, facilitating changes to the connection point with the car and simplifying installation. After adjusting the position of the connecting plate 4, it is fixed with screws. The sliding groove 6 and the sliders 7 on both sides of the connecting plate 4 facilitate its movement.

[0030] The ventilation slots 8 allow gas to flow inside the heat sink 1, thereby enhancing the heat dissipation effect. During installation, one of the movable pipes 10 is pulled out from inside the fixed pipe 9 and extended into the car's air intake position. Then, the position of the movable pipe 10 is fixed. During driving, the gas enters the interior of the fixed pipe 9 through the movable pipe 10, and then further enters the interior of the ventilation slots 8. After circulation, it is discharged from the other movable pipe 10.
