[0033] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0034] The specific implementation of this application is described in detail below in conjunction with specific embodiments.

[0035] like Figure 1 and Figure 4 As shown, a rear housing 100 of an automobile auxiliary light provided in an embodiment of the present application includes a main body, a first heat dissipation fin group, and a second heat dissipation fin group.

[0036] The first heat dissipation fin group is arranged on the leeward side of the main body, and the first heat dissipation fin group includes a plurality of U-shaped fins 105, which are arranged circumferentially around the center of the main body. The two ends of the U-shaped fins 105 extend to the outer periphery of the main body, and the middle part of the U-shaped fins 105 is bent toward the center of the main body.

[0037] The second heat dissipation fin group is arranged between two adjacent U-shaped fins 105, and the second heat dissipation fin group includes a plurality of curved fins spaced apart from the edge of the main body to the center, the two ends of the curved fins extend to the periphery of the main body, and the middle part of the curved fins is bent toward the center of the main body.

[0038] Among them, along the direction approaching the center of the main body, the heights of the multiple curved fins increase and are less than the height of the U-shaped fins 105, and there is a distance between the middle parts of two adjacent U-shaped fins 105 to form an air guide groove 106, and the air guide groove 106 extends toward the center of the main body.

[0039] In the embodiment of the present application, after passing through the windward side of the main body of the rear housing 100, the air will converge toward the central negative pressure zone on the leeward side of the main body. The height of the multiple curved fins increases gradually as they approach the center of the main body of the rear housing 100 and is less than the height of the U-shaped fins 105. The air flows through each curved fin and the U-shaped fins 105 in sequence, which has good air flow performance, can reduce air obstruction and reduce wind noise, while also enhancing the contact between the curved fins and the air, improving the heat dissipation effect. In addition, the center spacing between two adjacent U-shaped fins 105 is arranged to form an air guide groove 106 extending toward the center of the main body, allowing air to smoothly enter the central negative pressure zone, further reducing wind resistance and wind noise.

[0040] like Figure 2 and Figure 6 As shown, in some embodiments of the present application, the windward side of the main body has a front surface for mounting the light-emitting assembly 400 of the vehicle auxiliary light and the transparent mask 200. The leeward side, opposite the windward side, is provided with a first heat dissipation fin group and a second heat dissipation fin group. The first and second heat dissipation fin groups are integrally formed with the main body. This enhances heat conduction, improves heat dissipation, and simplifies the assembly process. It should be noted that the windward side and the leeward side merely represent two sides of the main body.

[0041] like Figure 1 As shown, in one example of the present application, the outer periphery of the main body can be square, such as Figure 8 As shown, the outer periphery of the main body can be circular. In other embodiments, the main body can be of other shapes, which are not limited here. The rear housings 100 with different main body shapes have basically the same heat dissipation fin structure on the leeward side. The following description uses a square rear housing 100 as an example.

[0042] like Figure 4 and Figure 5 As shown, as a preferred embodiment of the present application, a heat dissipation frame 107 or a first fin 101 is provided in the U-shaped fin 105, and the first fin 101 is provided in parallel with the plane portion of the U-shaped fin 105. It should be noted that the two ends of the U-shaped fin 105 are plane portions parallel to each other, and the middle portion is a curved portion connecting the two plane portions. In this embodiment, by providing a heat dissipation frame 107 or the first fin 101 in the U-shaped fin 105, it is possible to fully utilize the space and increase the area of ​​the fin to improve the heat dissipation effect. The first fin 101 is provided in parallel with the plane portion of the U-shaped fin 105, and the air duct formed between the two is directed to the center of the rear housing 100, so that the obstruction to the airflow can be reduced.

[0043] Specifically, refer to Figure 5As shown, in some embodiments, a heat dissipation frame 107 is provided in the upper and lower U-shaped fins 105, and a first fin 101 is provided in the left and right U-shaped fins 105. The heat dissipation frame 107 is a rectangular frame, and two parallel sides thereof are parallel to the plane part of the U-shaped fin 105, so that the air duct formed between the two is directed to the center of the rear shell 100, thereby reducing the obstruction to the airflow.

[0044] like Figure 4 and Figure 6 As shown, as another preferred embodiment of the present application, a second fin 102 is further provided between the heat dissipation frame 107 and the planar portion of the U-shaped fin 105, and the U-shaped fin 105 and the second fin 102 pass through the main body and extend to the windward side of the main body. In this embodiment, the U-shaped fin 105 and the second fin 102 pass through the main body and extend to the windward side of the main body, and are directly blown by the front of the airflow, thereby further improving the heat dissipation effect. In some embodiments, the U-shaped fin 105 and the second fin 102 only partially extend to the windward side of the rear housing 100 to avoid occupying too much space on the windward side. It should be noted that, as Figure 6 As described above, the air duct between the U-shaped fin 105 and the second fin 102 on the windward side is separated from the air duct between the U-shaped fin 105 and the second fin 102 on the leeward side, and the air flow cannot directly pass through the rear housing 100 through the above two air ducts.

[0045] like Figure 4 and Figure 5 As shown, as another preferred embodiment of the present application, at least part of the U-shaped fins 105 are provided with air vents near the center of the main body. In this embodiment, the provision of the air vents can reduce the air obstruction of the U-shaped fins 105 and reduce wind noise.

[0046] In some embodiments of the present application, Figure 5As shown, the rear shell 100 is observed from the perspective of the leeward side of the main body. The main body of the rear shell 100 has a rectangular outer periphery, and four U-shaped fins 105 are provided. The four U-shaped fins 105 are respectively arranged on the longitudinal and transverse symmetry axes of the rectangular outer periphery, and the openings of each U-shaped fin 105 are respectively facing one side of the rectangular outer periphery. The second heat dissipation fin group includes a third fin 103 and a fourth fin 104. The two ends of the third fin 103 and the fourth fin 104 extend to two adjacent sides of the rectangular outer periphery respectively. The height of the third fin 103 is smaller than that of the fourth fin 104, and the height of the fourth fin 104 is smaller than that of the U-shaped fin 105. The two U-shaped fins 105 arranged on the longitudinal symmetry axis of the rectangular outer periphery are provided with the air outlet, and the two air outlets are symmetrically arranged. The two U-shaped fins 105 arranged on the transverse symmetry axis of the rectangular outer periphery do not have the air outlet. In this embodiment, four U-shaped fins 105 are provided, corresponding to the four sides of the rectangular periphery, and a second heat dissipation fin group is provided in the area of ​​the four corners of the rectangular periphery, which can fully utilize the space behind the rear shell to arrange more heat dissipation fins and improve the heat dissipation effect, and the air outlets are symmetrically arranged to ensure air conduction in the two vertically arranged U-shaped grooves.

[0047] like Figure 5 and Figure 6 As shown in FIG. 1 , as another preferred embodiment of the present application, the thickness of the U-shaped fins 105, the curved fins, the first fins 101, the second fins 102, and the heat dissipation frame 107 gradually decreases in the direction away from the main body. In this embodiment, each fin is configured to have a thick base and a thin top. Each fin can absorb sufficient heat from the main body of the rear housing 100 and quickly transfer it to the thinner top, thereby improving the heat dissipation effect. Figure 5 As shown, a reinforcing rib 120 is provided on the main body of the rear housing 100 , and the reinforcing rib 120 is connected to each fin to improve the strength of each fin.

[0049] In the embodiment of the present application, a wire connecting the circuit board 410 and the external power supply is provided at the center of the rear shell. When the first lamp bead is lit, the light is gathered and emitted forward through the reflective cup 430, which can illuminate a farther place and can be used as a high beam. By lighting the second lamp bead, the light of the second lamp bead is irradiated onto the light guide bar 420, and the light is dispersed and transmitted through the light guide bar 420, which can be used as a daytime running light or a low beam. In this way, switching between multiple light sources can be achieved to meet the user's lighting needs. In addition, the heat dissipation structure of the rear shell 100 can reduce wind resistance, enhance heat dissipation, and ensure the normal use of the auxiliary light.

[0050] In one embodiment of the present application, the rear housing 100 is provided with a retaining groove 110 that matches the edge shape of the transparent mask 200. The edge of the transparent mask 200 is inserted into the retaining groove 110 to achieve the installation of the transparent mask 200. In some embodiments, the light-emitting assembly 400 further includes a decorative plate 450, which is disposed in front of the circuit board 410 to shield the circuit board 410.

[0051] like Figure 3 As shown in FIG. , as a preferred embodiment of the present application, a face frame 300 is sheathed around the transparent face shield 200. The face frame 300 is affixed to the rear housing 100 and has a hollowed-out area for light to pass through. In this embodiment, the transparent face shield 200 is a plastic shell that is easily damaged by impact. The face frame 300 is wrapped around the transparent outer surface to effectively protect the transparent face shield 200. The face frame 300 can be made of metal or hard plastic.

In this embodiment, the heat conducting portion 311 on the face frame 300 extends to abut against the outer wall of the transverse groove 210, which can protect the transparent mask 200, and the heat generated by the light guide strip 420 in the transverse groove 210 can also be transferred away through the heat conducting portion 311, thereby improving the heat dissipation effect. Specifically, in some embodiments, such as Figure 3 As shown, the transverse groove 210 is arranged in the middle of the transparent mask 200 and is arranged horizontally. Figure 7As shown, the mounting frame 440 is long and horizontally arranged. Multiple light guide strips 420 are spaced apart along the length of the mounting frame 440. Decorative panels 450 are placed above and below the mounting frame 440, each of which has two reflective cups 430 arranged horizontally. In this way, the light guide strips 420 can divide the entire transparent mask into two parts, improving the visual effect.

[0053] like Figure 3 As shown, as a preferred embodiment of the present application, the automotive auxiliary light further includes a protective cover 320 for shielding the hollowed-out area of ​​the face frame 300.

The mounting bracket is provided with an arc-shaped hole, and the rear housing 100 is provided with a threaded hole. A fastening screw passes through the arc-shaped hole and is connected to the threaded hole to achieve fixation of the mounting bracket to the rear housing 100. In this embodiment, the illumination angle of the automobile auxiliary light can be adjusted by rotating the mounting bracket and the rear housing 100. After adjustment, the mounting bracket is fixed to the rear housing 100 by passing the fastening screw through the arc-shaped hole and being connected to the threaded hole. When readjustment is required, it is only necessary to loosen the fastening screw and rotate the automobile auxiliary light. The fastening screw moves in the arc-shaped hole, making adjustment convenient and eliminating the need to completely remove the fastening screw to prevent loss.

[0055] like Figure 4 As shown, a wire is provided at the center of the rear housing 100 , and the wire passes through the rear housing 100 and is connected to the circuit board 410 .
