Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically an automotive headlight assembly. Background Technology

[0002] When a car headlight assembly is working, the light source in the headlight assembly generates a large amount of heat while emitting light. This heat accumulates in the headlight assembly cavity, raising the temperature inside the cavity. This, in turn, increases the operating temperature of various components within the headlight assembly cavity (such as the bulb, lens, etc.). This causes these components to operate at higher temperatures for extended periods, accelerating aging and severely impacting their lifespan. Furthermore, the high temperature inside the headlight assembly cavity makes it prone to fogging, significantly affecting the normal operation of the headlight assembly and posing a considerable threat to driving safety.

[0003] Meanwhile, a car headlight assembly with announcement number CN207935971U is disclosed, including a light distribution lens, a rear housing, and a reflector. The light distribution lens and the rear housing are sealed together to form a lamp cavity in the car headlight assembly. It also includes an LED headlight bulb and a wind-cooling heat dissipation device disposed on the rear housing. This application uses an LED headlight bulb with a built-in wind-cooling fan installed on the rear housing to dissipate heat from the lamp body, and at the same time, a wind-cooling heat dissipation device with a built-in external rotor centrifugal fan is provided on the rear housing to exhaust air from the lamp cavity for heat dissipation. This constitutes a dual heat dissipation structure, which significantly improves the heat dissipation effect of the car headlight assembly.

[0004] The high temperatures experienced during use of the aforementioned automotive headlight assembly can damage various electronic components and LEDs inside the headlight, accelerating their aging and failure process. For example, the lifespan of the headlight's driver power supply will be significantly shortened when operating at high temperatures; a headlight that might have been able to last 5 years may need to be replaced in 1-2 years due to heat dissipation issues.

[0005] Therefore, a new automotive headlight assembly is proposed to address the aforementioned issues. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The following describes an embodiment of this utility model based on its overall structure.

[0030] like Figures 1 to 4 As shown, this utility model provides an automotive headlight assembly, including a cooling fan 14. A cooling fin 15 is fixedly mounted on the rear end face of the cooling fan 14, and a heat-conducting column 16 is fixedly mounted on the rear end face of the cooling fin 15. A limiting block 17 is fixedly mounted in the middle of the rear end face of the cooling fan 14, and a nut 18 is fixedly mounted inside the limiting block 17. Through the cooling fan 14, cooling fin 15, and heat-conducting column 16, the cooling fan 14 can accelerate airflow and quickly remove heat; the cooling fin 15 increases the heat dissipation area, enabling more effective heat dissipation to the surrounding environment; and the heat-conducting column 16 can quickly conduct the heat generated by the bulb 10 to the cooling fin 15, improving heat dissipation efficiency and thus extending the service life of components such as the bulb 10.

[0031] In this embodiment, a fixing frame 12 is fixedly provided on the front end face of the cooling fan 14, and a cooling mesh 13 is fixedly provided inside the fixing frame 12. The cooling mesh 13 has cooling holes 19 inside. Through the cooling mesh 13, dust, debris and other objects can be prevented from entering the headlight assembly, avoiding damage to components such as the cooling fan 14 and the bulb 10, thereby improving the reliability and stability of the headlight assembly.

[0032] The nut 18 has a screw 5 inside, and a rotating shaft 4 is fixed on the right end face of the screw 5. A rectangular tube 3 is fixed on the outside of the rotating shaft 4, and the heat dissipation fins 15 are slidably arranged with the rectangular tube 3. Through the screw 5 and the nut 18, the rectangular tube 3 can move linearly under the drive of the screw 5, thereby realizing the fine adjustment of the position of the bulb 10.

[0033] A motor 11 is fixedly installed on the left end face of the rectangular tube 3, and the motor 11 is fixedly installed with the lead screw 5. Through the motor 11, the rotation of the lead screw 5 is automatically controlled. Users can easily adjust the position of the rectangular tube 3 by controlling the operation of the motor 11 without manual operation, which improves the convenience and accuracy of use.

[0034] A support plate 2 is fixedly provided on the rear end face of the rectangular tube 3, and a bulb 10 is fixedly provided on the rear end face of the support plate 2. The support plate 2 provides a stable mounting platform for the bulb 10, ensuring that the bulb 10 will not loosen or shift due to vibration or other factors during vehicle operation, thereby ensuring the stability and reliability of the light.

[0035] A protective shell 1 is fixedly provided on the outer side of the support plate 2. An annular groove 6 is provided inside the protective shell 1, and a threaded hole 7 is provided inside the annular groove 6. The protective shell 1 can prevent the bulb 10 from being impacted and damaged by external objects, and can also play a certain role in waterproofing and dustproofing, thus extending the service life of the bulb 10.

[0036] The threaded hole 7 has a threaded rod 9 inside, and a sealing ring 8 is fixed on the outside of the threaded rod 9. The sealing ring 8 is fitted with the annular groove 6. Through the threaded hole 7 and the threaded rod 9, the sealing ring 8 can fit tightly in the annular groove 6 to form an effective sealing structure, preventing water vapor, dust and other substances from entering the headlight assembly and protecting the bulb 10 and other components from the influence of the external environment.

[0037] The working principle and process of an automotive headlight assembly:

[0038] When installing the car headlight assembly, first, the bulb 10 is fixed to the rear end face of the support plate 2, which is then installed on the rear end face of the rectangular tube 3. Next, the protective shell 1 is installed on the outside of the support plate 2. Using the helical engagement of the threaded rod 9 and the threaded hole 7, the threaded rod 9 is screwed into the threaded hole 7, ensuring that the outer sealing ring 8 fits tightly into the annular groove 6, achieving a sealed installation of the protective shell 1. This effectively prevents dust, moisture, etc., from entering the headlight, creating a good environment for subsequent normal operation. Afterward, the motor 11 is connected to the vehicle's power system, and the bulb 10 is connected to the vehicle's lighting circuit system. When the vehicle needs lighting, the power to the bulb 10 is turned on, and the bulb 10 begins to illuminate, providing necessary lighting for the front of the vehicle. However, the bulb 10 generates a large amount of heat during illumination. If heat is not dissipated in time, it will affect the lifespan and lighting effect of the bulb 10. After the motor 11 starts, it drives the screw 5, which is fixedly connected to it, to rotate. Because the screw 5 is helically set in the screw... Inside the nut 18, the nut 18 is fixed inside the limiting block 17, which in turn is fixed in the middle of the rear end face of the radiator fan 14. Therefore, the rotation of the lead screw 5 will cause the radiator fan 14 to move linearly along the axial direction of the lead screw 5. When the radiator fan 14 moves forward, the fixing frame 12 and the heat dissipation mesh 13 fixed at its front end face also move forward. The radiator fan 14 starts to work, accelerating the airflow. Air enters through the heat dissipation holes 19 on the heat dissipation mesh 13, and quickly exchanges the heat generated by the bulb 10. The heat generated by the bulb 10 is transferred to the rectangular tube 3 through the support plate 2. The rectangular tube 3 is slidably set with the heat dissipation fins 15, and the heat is further transferred to the heat dissipation fins 15. The heat dissipation fins 15 increase the heat dissipation area, which helps to dissipate heat quickly. At the same time, the heat-conducting column 16 fixed at the rear end face of the heat dissipation fins 15 can also transfer the heat out. With the work of the radiator fan 14, the heat is quickly discharged from the headlight assembly, ensuring that the bulb 10 and other components work in a suitable temperature environment.
