[0002] Automotive lamps are an indispensable part of a vehicle. They not only play a role in lighting but also convey various signals to ensure driving safety. With the progress of technology, the materials and technologies of automotive lamps are constantly updated. In particular, LED lamps are becoming increasingly popular due to their advantages such as energy conservation, environmental protection, and long lifespan.

[0003] Chinese Patent Publication (Publication No.: CN 211902742 U) discloses a heat dissipation structure of an automotive lamp; it includes a lamp cover, an illuminating lamp is installed inside the lamp cover, a probe is movably connected to the right side of the outer wall of the illuminating lamp, a temperature sensor is installed on the right side of the probe, an alarm lamp is electrically connected to the front end face of the temperature sensor, the front end of the alarm lamp penetrates through the lamp cover and extends to the front side of the lamp cover, a ventilation pipe is fixedly connected to the front end face of the lamp cover, a solenoid valve is installed on the inner wall of the ventilation pipe, and a duct fan is fixedly installed at the front end of the inner wall of the lamp cover; by making the probe contact the outside of the illuminating lamp, the real-time temperature information of the illuminating lamp can be transmitted to the temperature sensor, and then when the temperature of the illuminating lamp is higher than the preset maximum temperature, the alarm lamp starts to flash, thereby reminding the user to open the solenoid valve and the duct fan, so that the air inside the lamp cover circulates with the outside air, thus achieving the effect of dissipating heat and cooling the illuminating lamp, and at the same time avoiding dust from entering the lamp cover when not ventilated;

A transparent lamp cover 4 is fixedly installed on the front side of the heat dissipation cover 3. A heat dissipation mechanism 2 is arranged in the inner cavity of the heat dissipation cover 3. The heat dissipation mechanism 2 includes ventilation holes 201, air guide covers 204, blades 205, pressing plates 212, insertion rods 213 and slots 214.

[0032] Embodiment 2

[0033] In one embodiment, sliders 5 are fixedly connected to the rear sides of the four sliding sleeves 209. Chutes 6 are provided in the rear sides of the two cavities 206. The rear sides of the four sliders 5 are slidably connected to the inner cavities of the two chutes 6.

[0034] By providing the sliders 5 and the chutes 6, when the sliding sleeve 209 moves, it can drive the slider 5 to slide in the inner cavity of the chute 6, improving the stability of the sliding sleeve 209 during movement. By providing the pulling grooves 7, the movement of the pull rod 215 can be limited to prevent the pull rod 215 from shifting during movement.

By providing the limiting grooves 9, the movement of the cavity 206 can be limited to prevent the cavity 206 from shifting during movement. By providing the connecting plates 10 and the connecting holes 11, it is convenient to connect the lamp body 1 to the vehicle body. By providing the mounting plates 12 and the mounting holes 13, it is convenient to connect the heat dissipation cover 3 to the vehicle body.

[0035] When the present utility model is working: The heat dissipation fan 203 generates an air flow, and the heat in the lamp body 1 is dissipated outward through the cooperation of the ventilation holes 201, the air guide cover 204 and the blades 205. Since the heat dissipation fan 203 is inside the heat dissipation cover 3, it will not block the light-transmitting lamp cover 4 and will not affect the light-transmitting effect of the light-transmitting lamp cover 4. By holding the pull rod 215 and moving it outward, the pull rod 215 drives the sliding sleeve 209 to slide outward on the surface of the sliding rod 207, and compresses the return spring 208, causing the return spring 208 to deform. Through the cooperation of the connecting rod 210 and the fixing block 211, the pressing plate 212 and the inserting rod 213 are driven to move outward, so that the inserting rod 213 disengages from the inner cavity of the inserting slot 214, separating the heat dissipation cover 3 from the lamp body 1, facilitating the cleaning of the dust inside the heat dissipation cover 3 and the light-transmitting lamp cover 4, and improving the heat dissipation effect of the heat dissipation fan 203;

[0036] When the heat dissipation cover 3 needs to be installed on the lamp body 1, by holding the pull rod 215 and moving it outward, the pull rod 215 drives the sliding sleeve 209 to slide outward on the surface of the sliding rod 207, and squeezes the return spring 208, causing the return spring 208 to deform. Through the cooperation of the connecting rod 210 and the fixing block 211, the pressing plate 212 and the insertion rod 213 are driven to move outward, so that the insertion rod 213 moves outward. Place the lamp body 1 inside the heat dissipation cover 3, align the slot 214 with the limiting slot 9. Then release the pull rod 215, and the return spring 208 deforms again due to the loss of the acting force, driving the sliding sleeve 209 to slide inward on the surface of the sliding rod 207, driving the pressing plate 212 and the insertion rod 213 to move inward, so that the inner sides of the insertion rods 213 penetrate through the inner cavity of the limiting slot 9 and are inserted into the inner cavity of the slot 214, fixing the heat dissipation cover 3 and the lamp body 1, which is convenient for people to use.

[0037] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
