[0002] The automobile lamp is the lamp on the vehicle, mainly used for road lighting when driving at night and sending various vehicle driving signals to prompt other road users. The automobile lamp includes a headlamp, a tail lamp, a turn signal lamp, etc., wherein the headlamp is divided into a low beam, a high beam, a front turn signal lamp, a front position lamp (wide indication lamp), a front fog lamp, etc. The design of these lamps aims to improve the driving safety at night or in bad weather, to ensure that the driver can clearly see the road conditions in front, and at the same time, to make other road users aware of the existence and movement of the vehicle, so as to avoid traffic accidents.

[0003] During the night, the automobile lamp will emit a large amount of heat due to the loss of internal resistance during the long-term use of the automobile lamp, which is accumulated in the automobile lamp. Since the automobile will also travel in the rain, the automobile lamp will be designed as a waterproof structure to prevent the immersion of external rainwater. However, this design will cause the automobile lamp to be in a relatively closed state, which will easily cause the automobile lamp to be difficult to dissipate the heat in the automobile lamp, and long-term use will cause the temperature in the lampshade to rise rapidly, which will easily affect the service life of the automobile lamp.

[0004] Therefore, based on the above problems, there is an urgent need for an automobile lamp support that can prevent heat accumulation in the automobile lamp, causing continuous temperature rise. SUMMARY

[0005] In view of the current difficulty of heat dissipation of the automobile lamp, the present application provides an automobile lamp support with heat dissipation function to solve the above problems.

When the temperature sensed by the temperature sensing device exceeds the set value, the motor can drive the lifting protective shell to expose the air holes to the outside for cooling.

[0008] Optionally, the air holes are arranged in an array of multiple rows and multiple columns.

[0009] Optionally, a rain shield is arranged on one side of the support frame and above the air holes.

[0010] Optionally, a gravity sensor is arranged above the rain shield, a rain-collecting box is arranged above the gravity sensor, and the gravity sensor is electrically connected to the single-chip microcomputer; when the gravity sensor senses that the gravity of rainwater in the rain-collecting box exceeds a set weight, the single-chip microcomputer drives the lifting protective shell to close the air vent, thereby preventing water from entering.

[0011] Optionally, a heat dissipation fan is arranged inside the support frame, and the heat dissipation fan is arranged to direct air towards the air vent.

[0012] Optionally, a water outlet is arranged on the sidewall of the rain-collecting box, and a drainage channel is fixed to the outside of the rain-collecting box and is in communication with the water outlet.

[0013] Technical effects:

[0014] The application discloses a support frame for a car lamp, which is provided with an air vent on one side for heat dissipation, and a lifting protective shell is arranged outside the air vent; when a temperature sensing device senses that the temperature inside the car lamp exceeds a set temperature, a single-chip microcomputer controls the lifting protective shell to expose the air vent to the outside for heat dissipation.
