Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, in particular to an automobile headlight. Background Art
[0002] Car headlights, also known as headlamps, are usually installed on both sides of the car's head and are used to illuminate the road at night. However, as consumers' requirements for car use increase, car headlights, as one of the important accessories, also need further improvement.
[0003] The announcement number is CN218032967U, and the subject name is a kind of anti-fogging structure for automobile headlights. It proposes that "the upper air inlet box can be used to intake air into the headlight housing when the vehicle is driving, and then be discharged through the lower air outlet box, so that the air can flow in the headlight housing, which can improve the cooling of the headlight housing, and can effectively remove the fog in the headlight housing to prevent fogging. When in use, the defogging efficiency is faster and the effect is better. The humidity monitor can monitor the humidity in the headlight housing when in use. When the humidity is high, the micro motor can be started by the controller 7 to open the adjusting baffle, which can facilitate the intake of air into the headlight housing, thereby achieving the effect of active dehumidification."
[0004] From the above disclosed technical contents, the above existing technology realizes the anti-fogging effect by setting a ventilation structure to enable the air inside the automobile headlights to circulate with the external environment. This is feasible in theory, but in actual use, the automobile has to face various bad weather conditions, such as strong winds and heavy rains, which affect the use of the ventilation structure and will cause rainwater to enter the interior of the automobile headlights through the ventilation structure. It can be seen that the existing technology still needs further improvement. Utility Model Content
