Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting heat dissipation technology, and more specifically, it relates to automotive lighting modules with active heat dissipation. Background Technology

[0002] Suitable operating temperature is crucial for the luminous efficiency and color stability of vehicle lights. Overheating can cause changes in the filament resistance of the bulb, resulting in decreased light brightness and color shift, which can affect the driver's judgment of road conditions. Heat dissipation can keep the vehicle lights within a reasonable operating temperature range, ensuring stable light performance and providing the driver with good visual conditions. Existing vehicle light modules with active cooling systems face harsh working environments due to dust and noise generated during driving, leading to a higher fan failure rate. Failure to maintain these systems in a timely manner can easily cause the vehicle lights to overheat, thus affecting driving safety. Therefore, a vehicle light module with active cooling system is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a vehicle headlight module with active cooling, which can automatically switch power when the cooling fan motor fails. This solves the problem mentioned in the background art, where dust and noise generated during driving create a harsh working environment for the active radiator, leading to a higher fan failure rate. Failure to repair in a timely manner can easily cause the headlight to overheat, thus affecting driving safety.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vehicle headlight module with active heat dissipation, comprising an LED headlight module and a bracket.

Multiple fan blades are fixed to the outer circumference of the rotating ring. A first transmission disk is slidably connected to the outer side of the output shaft of the first motor. A second transmission disk is slidably connected to the outer side of the output shaft of the second motor. A groove is formed on the side of the second transmission disk away from the rotating ring. A spring abuts against the inner side of the groove. Two connecting belts are also fixed to the side of the second transmission disk away from the rotating ring. A connecting groove is formed on the opposite side of the first and second transmission disks. A connecting rod is rotatably connected between the two connecting grooves. The connecting rod is made of Teflon material.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a vehicle headlight module with active heat dissipation, including an LED headlight module 1 and a bracket 2. A first motor 3 and a second motor 4 are fixed to the inner side of the bracket 2. A first connecting ring 5 and a second connecting ring 6 are respectively fixed to the opposite side of the first motor 3 and the second motor 4. Two blades 16 are fixed to the inner side of the second connecting ring 6. A rotating ring 7 is slidably connected between the first connecting ring 5 and the second connecting ring 6. A ball bearing 17 is provided between the rotating ring 7 and the first connecting ring 5 and the second connecting ring 6. Multiple fan blades 8 are fixed to the outer circumference of the rotating ring 7. A first transmission disk 9 is slidably connected to the outer side of the output shaft of the first motor 3. A second transmission disk 10 is slidably connected to the outer side of the output shaft of the second motor 4. A groove 11 is formed on the side of the second transmission disk 10 away from the rotating ring 7. A spring 1 is abutting the inner side of the groove 11. 2. Two connecting belts 13 are fixed on the side of the second transmission disc 10 away from the rotating ring 7. Connecting grooves 14 are opened on the opposite side of the first transmission disc 9 and the second transmission disc 10. A connecting rod 15 is rotatably connected between the two connecting grooves 14. The connecting rod 15 is made of Teflon. The center of the first connecting ring 5 and the center of the second connecting ring 6 are on the same axis. The center of the rotating ring 7 and the center of the second connecting ring 6 are on the same axis. The center of the first transmission disc 9 coincides with the center of the output shaft of the first motor 3. The first transmission disc 9 and the rotating ring 7 mesh and drive each other. The center of the second transmission disc 10 coincides with the center of the output shaft of the second motor 4. The second transmission disc 10 and the rotating ring 7 mesh and drive each other. One end of the connecting belt 13 is fixedly connected to the outside of the second motor 4. One end of the spring 12 abuts against the outside of the second motor 4. The first motor 3 drives the rotating ring 7 to rotate via the first transmission disk 9. The rotating ring 7 drives multiple fan blades 8 to rotate, thereby driving air to dissipate heat from the LED headlight module 1. When the internal speed sensor of the first motor 3 detects a fault, it starts the second motor 4. The second motor 4 drives the second transmission disk 10 to rotate. During this process, the connecting belt 13 on the second transmission disk 10 is cut by the blade 16 on the second connecting ring 6 and breaks, thereby releasing the spring 12. The spring 12 pushes the second transmission disk 10 to engage with the rotating ring 7, thereby driving the rotating ring 7 and the fan blades 8 to rotate. At the same time, the second connecting ring... 6. The first transmission disc 9 is moved by the connecting rod 15, so that the first transmission disc 9 is away from the rotating ring 7. This prevents the rotating ring 7 from transmitting power to the first motor 3 when it rotates, thus avoiding the waste of some power of the second motor 4. At the same time, it prevents the first motor 3 from jamming and jamming the second motor 4. Through the above process, the power can be automatically switched when the cooling fan motor is damaged. This solves the problem that the active radiator works in a harsh environment due to dust and noise generated during driving, which increases the fan damage rate. If maintenance is not carried out in time, the headlights may overheat, thus affecting driving safety.

[0022] The specific usage and function of this embodiment: In this utility model, the first motor 3 drives the rotating ring 7 to rotate through the first transmission disk 9. The rotating ring 7 drives multiple fan blades 8 to rotate, thereby driving air to dissipate heat from the LED vehicle light module 1. When the internal speed sensor of the first motor 3 detects a fault, it starts the second motor 4. The second motor 4 drives the second transmission disk 10 to rotate. During this process, the connecting belt 13 on the second transmission disk 10 is cut by the blade 16 on the second connecting ring 6 and breaks, thereby releasing the spring 12. The spring 12 pushes the second transmission disk 10 to mesh with the rotating ring 7, thereby driving the rotating ring 7 and the fan blades 8 to rotate. At the same time, the second connecting ring 6 pushes the first transmission disk 9 to move through the connecting rod 15, so that the first transmission disk 9 moves away from the rotating ring 7, avoiding the power being transmitted to the first motor 3 when the rotating ring 7 rotates, thus avoiding the waste of some power of the second motor 4. At the same time, it avoids the first motor 3 from jamming and jamming the second motor 4. Through the above process, the power can be automatically switched when the cooling fan motor is damaged.
