Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a car lamp with a high-efficiency heat dissipation structure. Background Art

[0002] Car lights are tools for car lighting and issuing various vehicle driving signal prompts. As an important component of the vehicle, car headlights not only affect the safety of driving at night, but also reflect the progress of automobile technology. The headlights used in cars mainly include halogen headlights, xenon headlights and LED headlights. Since car headlights will generate a lot of heat accumulation during long-term use, heat dissipation equipment is needed to assist the headlights in temperature regulation to ensure the service life of the headlights. The heat dissipation equipment usually uses heat dissipation fins and fans to drive air flow for temperature control.

[0003] Although the heat dissipation structure used in the existing car lights has many benefits, it still has the following problems: it lacks a cleaning structure for the heat dissipation device, which results in a large amount of fibrous foreign matter and dust particles adhering to the surface of the heat dissipation fins during long-term use of the heat dissipation device, affecting the effect of the heat dissipation fins and thus affecting the temperature control accuracy of the car lights.

[0030] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the utility model describes a vehicle lamp with a high-efficiency heat dissipation structure, comprising a lampshade 1, a connecting frame 2, a connecting ring 22 and a terminal 14.

A connecting ring 22 is rotatably installed inside the support ring 21, and a circular array of fan blades 23 are installed on the inner wall of the connecting ring 22.

[0031] During use, the motor drives the connecting ring 22 to rotate in a circle through the gear 28 and the rack, so that the fan blades 23 drive the air flow, and the air flow flows in through the gap between the support ring 21 and the lampshade 1, and is arranged side by side to the lower end of the interior of the connecting ring 22. The heat dissipating fins 16 transfer the heat inside the lampshade 1, and the heat dissipation effect of the heat dissipating fins 16 is improved through the flow of air. The connecting ring 22 drives the support rod 24 and the brush 25 to rotate, and the brush 25 contacts the outer wall of the heat dissipating fin 16, so that foreign matter adhered to the outer surface of the heat dissipating fin 16 falls off, and the foreign matter moves according to the direction of the air flow until it is intercepted by the filter 26, thereby achieving the purpose of collecting foreign matter.

[0032] In order to supply power to the light source board 15, for example, Figure 3 As shown, a light source board 15 is provided at the lower end of the inner wall of the lampshade 1 , and a connection terminal 14 is provided on one side of the outer wall of the lower end of the lampshade 1 . The connection terminal 14 is electrically connected to the light source board 15 .

[0033] When in use, an external circuit is connected to the connection terminal 14 to provide power to the light source board 15 , and an external control device can control the working state of the light source board 15 .

[0034] In order to gather light, for example, Figure 2 As shown, a light collecting piece 13 is embedded and installed on one side of the upper end of the inner wall of the lampshade 1. The light collecting piece 13 adopts an arc-shaped design, and the outer wall of the fixing block 11 is installed with connecting pieces 12 distributed in a circular array.

[0035] When in use, the focusing sheet 13 can focus the light inside the lampshade 1 to ensure that the light emission angle meets the requirements, and the external fixing parts can fix the lampshade 1 through the connecting piece 12, so that the lampshade 1 is fixed to the required position of the vehicle.

[0036] In order to maintain the heat dissipation effect of the heat dissipation fins 16, for example, Figure 4 As shown, a support rod 24 is installed on one side of the inner wall of the connecting ring 22 , and brushes 25 equidistantly and parallelly distributed are installed on the outer wall of the upper end of the support rod 24 , and the brushes 25 are located between the heat dissipation fins 16 .

[0037] When in use, the support rod 24 keeps the brush 25 in a stable position, and the brush 25 contacts the outer wall of the heat sink fin 16, which can scrape and clean foreign matter adhering to the outer wall of the heat sink fin 16 and keep the outer wall of the heat sink fin 16 relatively clean.

[0038] For air flow, for example, Figure 4 As shown, a motor body 27 is installed on one side of the outer wall of the support ring 21, a gear 28 is provided on the outer wall of the lower end of the motor body 27, and a rack distributed in a circular array is opened on the lower end of the outer wall of the connecting ring 22, and the gear 28 is engaged with the rack.

[0039] When in use, the motor body 27 drives the gear 28 to rotate in a circular motion, and the gear 28 and the rack are engaged to drive the connecting ring 22 to rotate in a circular motion, thereby driving the fan blades 23 to drive air flow.

[0040] In order to collect foreign matter, for example, Figure 4 As shown, a filter screen 26 is threadedly connected to one side of the lower end of the inner wall of the connecting ring 22. The filter screen 26 does not contact the fan blades 23, and a wiring hole is opened at the center of the filter screen 26. The wiring hole is located at the lower end of the terminal 14, and a sealing ring is fixed to the inner wall of the wiring hole.

[0041] When in use, the filter 26 filters and collects foreign matter inside the connecting ring 22 to prevent the foreign matter from scattering, and the external line is located inside the wiring hole, and the sealing between the filter 26 and the external line is ensured by the sealing ring.

[0042] In order to provide air flow space, for example, Figure 2 As shown, the outer diameter of the support ring 21 is consistent with the outer diameter of the lampshade 1 , and the working position of the support ring 21 is located at the lower end of the heat dissipation fins 16 .

[0043] When in use, external air flows into the interior of the connecting ring 22 through the gap between the supporting ring 21 and the lampshade 1 .

[0045] The staff manually rotates the filter 26 so that the filter 26 is fixed inside the connecting ring 22, and the sealing ring squeezes the external circuit to maintain the sealing between the filter 26 and the external circuit, preventing foreign matter from leaking through the gap between the filter 26 and the external circuit. The staff can collect the filtered foreign matter by removing the filter 26;

[0046] The motor body 27 drives the connecting ring 22 to rotate in a circular motion through the gear 28 and the rack, thereby causing the fan blades 23 to drive the air flow, so that the airflow flows through the gap between the support ring 21 and the lampshade 1 and flows toward the lower end of the inner part of the connecting ring 22;

[0047] The heat dissipation fins 16 transfer the heat inside the lampshade 1 and improve the heat dissipation effect of the heat dissipation fins 16 through the flow of air, thereby improving the heat dissipation effect of the light source board 15 inside the lampshade 1 and ensuring the service life of the entire device.

[0048] The connecting ring 22 drives the support rod 24 and the brush 25 to rotate, and the brush 25 contacts the outer wall of the heat dissipation fin 16, so that foreign matter adhering to the outer surface of the heat dissipation fin 16 falls off, ensuring the cleanliness of the outer wall of the heat dissipation fin 16 and ensuring the heat dissipation efficiency of the heat dissipation fin 16;

[0049] Foreign matter moves according to the direction of air flow until it is intercepted by the filter 26, thereby achieving the purpose of collecting the foreign matter and preventing the foreign matter from being scattered.
