Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an external heat dissipation system for lens-type automotive lights. Background Technology

[0002] With the intensification of market competition, diversified communication in automobiles has become one of the decisive factors for consumers when choosing a new car. Headlights are an important factor in diversified communication. The pursuit of diversified communication mainly stems from the performance of headlights, which places high demands on them. This pursuit of performance is mainly reflected in the lenses of our headlights.

[0003] Currently, most lenses on the market are located inside our car headlights. With the improvement of lens performance, the heat dissipation solutions inside the lens lamps result in very high internal temperatures, as shown in the dual-lens LED front fog light disclosed in patent CN108692255A. Due to the requirements for sealing and dustproofing of lamps, lenses are now basically located inside the lamps, especially in some lamps with limited space. Traditional lenses have high heat dissipation pressure, which is detrimental to the lifespan of the lamps, and also limits dimming and adds a lot of unnecessary costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an external heat dissipation system for lens-mounted vehicle lights, which externalizes the heat dissipation of the lens, effectively improving the heat dissipation effect.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The external heat dissipation system for the lens-type automotive headlight includes a headlight body, a sealing ring, a lens module, a sealed radiator A, a sealed radiator B, and a fan. Part of the lens module is located inside the headlight body, and the other part of the lens module is located outside the headlight body. The lens module is mounted on the sealed radiator B via the sealed radiator A, and the fan is located outside the sealed radiator B. One end of the sealing ring is connected to the sealed radiator A and / or the sealed radiator B, and the other end of the sealing ring is connected to the headlight body.

[0006] Further or preferred: The lens module body is connected to the sealed heat sink A by screws, and the sealed heat sink B is connected to the sealed heat sink A by screws.

[0007] The lamp body and the edge of the sealing ring are sealed together by a snap-fit ​​structure.

[0008] The sealing radiator A is assembled with one end of the sealing ring, and the sealing radiator B is used to press the sealing ring to achieve a sealing setting.

[0009] The lamp body is provided with a ring of lamp body sealing ribs, and the edge of the sealing ring is provided with sealing ring buckles. The sealing ring buckles and the lamp body sealing ribs work together to achieve a sealing setting.

[0010] The sealed radiator A has a groove, and one end of the sealing ring has a sealing rib. The bottom of the sealing rib interferes with the groove of the sealed radiator A. The sealing is achieved by pressing the sealing ring with the sealed radiator B.

[0011] The sealed radiator A and sealed radiator B are connected by screws, and the fan is connected to the sealed radiator B by screws. The fan is a waterproof fan.

[0012] Compared with the prior art, this utility model has the following advantages: The external heat dissipation system of this lens lamp is reasonably designed. By semi-externalizing the lens module, the internal space of the lamp body is optimized, and the heat dissipation effect of the lens is increased without affecting the dimming of the lens, thus improving the heat dissipation performance of the lens. The soft characteristics of the sealing ring and the expansion ring of the sealing ring are used to ensure the range of dimming movement and sealing. Attached Figure Description

The lens body 6 and the sealed heat sink A 5 are assembled first, and the lens body 6 and the sealed heat sink A 5 are connected by screws; both the lens body 6 and the sealed heat sink A 5 are located inside the lamp body 7; specifically, there are 4 screw holes on the main plate and side plate of the sealed heat sink A 5, which are screwed to the lens body for tightening.

[0021] like Figure 3 As shown, the lamp body 1 and the sealing ring 2 are sealed together by a snap-fit ​​structure. The sealing heat sink A is assembled with one end of the sealing ring, and the sealing heat sink B presses down on one end of the sealing ring to achieve a seal. The lamp body has a sealing rib 9, and the edge of the sealing ring has a sealing ring buckle 8. The sealing ring buckle and the lamp body sealing rib cooperate to achieve a seal.
