[0003] In order to improve the heat dissipation effect, some existing headlights are designed with a gas circulation pipe on the lamp housing and a filter embedded in the pipe to effectively filter dust. Although this design can prevent dust from entering the interior of the lamp housing and maintain its cleanliness, when the gas flows through the filter, some dust particles will adhere to the surface of the filter, resulting in a decrease in the ventilation performance of the filter, which in turn easily affects the heat dissipation effect of the headlight. Therefore, a heat dissipation mechanical structure of the headlight assembly is proposed. Utility Model Content

When the gas flows through the filter, some dust particles will adhere to the surface of the filter, resulting in a decrease in the ventilation performance of the filter, which in turn easily affects the heat dissipation effect of the headlight.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a heat dissipation mechanical structure of a vehicle lamp assembly, comprising a lamp housing, lamp beads, a heat conducting plate, a radiator and a light-transmitting mirror, and also comprising:

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The present application realizes rapid cooling of the interior of the headlight by arranging an air inlet, an air outlet, a heat dissipation mechanism and a filtering mechanism. When the headlight is in working state, the air inlet, the air outlet and the heat dissipation mechanism work together to effectively discharge part of the heat inside the lamp housing, thereby ensuring the normal operating temperature of the headlight. At the same time, the filter in the filtering mechanism filters the incoming airflow, effectively blocking dust particles from entering the lamp housing, thereby maintaining a clean environment inside the headlight. When some dust particles in the airflow adhere to the surface of the filter, the fan blades driven by the power of the airflow will drive the rotating rod to rotate, causing the cleaning rod to rotate, thereby cleaning the dust particles attached to the surface of the filter in real time. This design effectively avoids the situation where dust particles adhere to the surface of the filter, resulting in a decrease in the ventilation performance of the filter, thereby ensuring the continuous and stable heat dissipation effect inside the headlight.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 4 , the utility model provides a technical solution:

[0027] A heat dissipation mechanical structure of a vehicle lamp assembly includes a lamp housing 1, a lamp bead 2, a heat conducting plate 3, a radiator 4 and a light transmitting mirror 5, and also includes:

[0028] The air inlet 6 is provided on the outer surface of the lamp housing 1;

[0029] The exhaust port 7 is provided on the outer surface of the lamp housing 1 and is located on one side of the air inlet 6;

[0030] The heat dissipation mechanism 8 is arranged on the upper part of the lamp housing 1;

[0031] The filter mechanism 9 is arranged on the upper part of the lamp housing 1 and is fixedly connected to the heat dissipation mechanism 8 .

[0032] Specifically, such as Figure 1 and Figure 2 As shown, there are multiple air inlets 6 and multiple air outlets 7 , which can effectively disperse the airflow, thereby improving the air circulation efficiency inside the lamp housing 1 .

[0033] Specifically, such as Figure 1 、 Figure 2 and Figure 3As shown, the heat dissipation mechanism 8 includes a fan 81 arranged on the upper part of the lamp housing 1, the input end of the fan 81 is provided with a connecting pipe 1 82, the output end of the fan 81 is provided with a connecting pipe 2 83, the connecting pipe 2 83 is fixedly connected to the lamp housing 1, and the output end of the connecting pipe 2 83 is located at the air inlet 6.

[0034] Specifically, such as Figure 1 、 Figure 3 and Figure 4 As shown, the filtering mechanism 9 includes a shell 91 arranged on the upper part of the lamp housing 1, the inner wall of the shell 91 is provided with a support frame 92, the inner surface of the shell 91 on one side of the support frame 92 is provided with a filter 93, the inner surface of the support frame 92 is rotatably connected to a rotating rod 94, the rotating rod 94 is rotatably connected to the filter 93, the outer surface of the rotating rod 94 is provided with fan blades 95, and the outer surface of the rotating rod 94 away from the fan blades 95 is provided with a cleaning rod 96, and the cleaning rod 96 is located on the outside of the filter 93.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, the filter screen 93 is cylindrical, which can increase the contact area with the external airflow, thereby improving the filtering efficiency of the external airflow.

[0036] Specifically, such as Figure 1 、 Figure 3 and Figure 4 As shown, the materials of the connecting pipe 1 82, the connecting pipe 2 83, the shell 91 and the support frame 92 are all made of polypropylene plastic, which has the characteristics of high temperature resistance, light weight, high hardness and corrosion resistance.

[0037] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the exhaust port 7 is provided with a one-way valve 10, and the air flow input end of the shell 91 is provided with a one-way valve 2 11. When air flows into the lamp housing 1, the one-way valve 10 and the one-way valve 2 11 can automatically open to allow the air flow to pass smoothly. When there is no air flow inside the lamp housing 1, the one-way valve 10 and the one-way valve 2 11 can automatically close to seal the exhaust port 7 and the air flow input end of the shell 91 respectively, thereby reducing the intrusion of external pollutants.

[0038] Working principle: When in use, connect the airflow input end of the shell 91 to the external air duct. When the headlight starts working, the lamp bead 2 emits light and generates heat. Part of the heat is effectively transferred to the radiator 4 through the heat conduction plate 3 for heat dissipation. At the same time, the fan 81 is started, and the suction force it generates allows the external airflow to smoothly pass through the external air duct into the interior of the shell 91. After entering the shell 91, the airflow will first be filtered by the filter 93 to remove impurities and dust particles therein. The filtered airflow then contacts the fan blades 95. Driven by the airflow, the fan blades 95 will begin to rotate slowly, thereby driving the rotating rod 94 Rotate slowly to make the cleaning rod 96 rotate slowly to clean the dust particles attached to the surface of the filter 93 to prevent the filter 93 from being blocked. At the same time, the airflow filtered by the filter 93 will continue to enter the interior of the lamp housing 1 through the connecting pipe 1 82, the fan 81 and the connecting pipe 2 83. When the airflow flows inside the lamp housing 1, it will take away some heat and then be discharged through the exhaust port 7. During this process, the one-way valve 1 10 and the one-way valve 2 11 are both in an automatically open state to ensure the smooth flow of the airflow. When the car light is finished working, the one-way valve 10 and the one-way valve 2 11 will automatically close to seal the exhaust port 7 and the airflow input end of the shell 91 respectively.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
