Forced defogging device for automobile headlamp

Abstract

The invention relates to the technical field of automobile components, and discloses a forced defogging device for an automobile headlamp. The forced defogging device comprises a lamp holder, whereina decorative plate is fixedly arranged on the front side of the lamp holder; a lampshade is fixedly arranged on the front side of the decorative plate; positioning blocks are fixedly arranged on the front sides of the bottom ends of the decorative plate and the lampshade; an insertion block is fixedly arranged at the bottom of the lamp holder; a first fixing part is fixedly arranged on the back side of the right end of the lamp holder; a second fixing part is fixedly arranged on the back side of the top of the lamp holder; the back side of the lamp holder is provided with a first wiring port;and the back side of the lamp holder is provided with a second wiring port positioned in the right side of the first wiring port. Compared with the defogging devices in the market, the forced defogging device for the automobile headlamp has the advantages of facilitating the repair and maintenance operations of a user, shortening the defogging time to 3 to 5 minutes, avoiding the influence on thelighting effect during driving and lowering the potential safety hazard for a driver driving on the road, along with simple structure, lower purchasing cost and rapid defogging.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a device for forced defogging of automobile headlights. Background technique [0002] The headlight is an important component of the electric device of the car. It not only plays the role of appearance decoration, but also provides lighting and signal indication for the driver and other vehicle users during night driving. The shape of the headlight has changed in recent years. With the development trend of flat narrowing, the internal space of lamps is getting smaller and smaller, which brings great difficulties to the design of internal and external ventilation systems of lamps. In addition, with sunlight and light source radiation, the temperature distribution inside the lamp is uneven, and the internal convection and communication between lamps and lanterns The process of external air exchange is very complicated, and if the fog problem occurs in the functional area o...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for forced defogging of automobile headlights, which has the advantages of good defogging effect, etc., and solves the problems in the prior art mainly by optimizing the temperature imbalance inside and outside the headlights. , starting from the internal air circulation and temperature to analyze the root of the fog in the headlights, and improving the fogging problem by increasing the air flow rate inside the headlights and exchanging air with the outside, because the headlights have a small space and are greatly affected by the environment So solve the problem of unsatisfactory fog effect
