Problems solved by technology

[0002] With the advent of winter, the gradually widening temperature difference between day and night often causes the headlights to fog up, which affects the light transmittance of the car headlights, weakens the lighting effect at night, and poses a huge hidden danger to the safety of driving at night. In addition, the fogging of the headlights will easily cause the headlights to form astigmatism, which will not form a proper focus correctly, and will cause dazzling light pollution to vehicles in the opposite direction; and the relevant electrical components in the lights will also be corroded by water vapor, which will affect the use life

Embodiment 1

[0025] see Figure 1-5 , a car headlight with good waterproof effect, comprising a lamp housing 1, a lamp tube 2, a reflector 3 and a light distribution mirror 20, the light distribution mirror 20 is installed in the lamp housing 1, and the lamp housing 1 and the distribution mirror A light tube 2 and a reflector 3 are installed in the cavity formed by the light mirror 20. The light tube 2 is installed in the reflector 3, and an air hole 19 is also opened on the lamp housing 1. The light distribution mirror 20 A generation module is also provided below, and the generation module includes a reaction chamber 13, a limiting chamber 14, a first wedge block 15 and a fan 18, and the reaction chamber 13 communicates with an elastic bag 22, and the elastic bag 22 is installed in a position-limiting In the cavity 14, a small hole is also opened above the limiting cavity 14; a first wedge-shaped block 15 and a second wedge-shaped block 16 are provided in the gap directly above the small...

Embodiment 2

[0033] In order to further improve the water collection capacity of this design, improvements have also been added on the basis of Embodiment 1, the improvements are: please refer to Figure 1-5 , the opening and closing plate 12 includes a fourth expansion plate 121, a third expansion plate 122, a second expansion plate 123, and a first expansion plate 124, which are sequentially arranged from bottom to top, and are rotatably connected by a turning slot 126, and the turning slot 126 is pierced with a rotating shaft 9, and the bottom surface of the first expansion plate 124 is also fixedly connected with a support shaft 11, and the rotating shaft 9 and the support shaft 11 are fixedly connected; the first expansion plate 124, the second expansion plate 123 and the third expansion plate 122 are provided with sliding grooves 125, and the end faces of the fourth expansion plate 121, the third expansion plate 122, the second expansion plate 123 and the first expansion plate 124 are...

Embodiment 3

[0037] In order to sweep away the moisture on the surface of the light distribution mirror 20, improvements are also added on the basis of the above-mentioned embodiments, the improvements are: please refer to Figure 1-5 , a gear 10 is installed on the rotating shaft 9; and the side of the rotating shaft 9 is also provided with a sweeping mechanism, and the sweeping mechanism includes a brush plate 4, a connecting column 6 and a rack 8, and the brush plate 4 It is fixedly connected to the connecting column 6, and the connecting column 6 is penetrated in the rack 8, and the rack 8 and the gear 10 are meshed for transmission; the brush plate 4 is also bonded with a brush 5 .

[0038] A clamping block 7 is also provided on the side of the connecting column 6 , and is slidably clamped in the lamp housing 1 through the clamping block 7 .

[0039] When in use, when the power mechanism drives the rotating shaft 9 to rotate, it further drives the gear 10 to rotate, and through the me...

Abstract

The automobile headlamp with the good waterproof effect comprises a lamp shell, a lamp tube, a reflecting plate and a lens, a generation module is further arranged below the lens and comprises a reaction cavity, a limiting cavity, a first wedge block and a fan, preferably, a flow guide groove is formed in the lens, and an opening and closing plate is arranged below the lens; when water vapor is condensed on the lens, water drops firstly move into the flow guide groove, then slide onto the opening and closing plate through the flow guide effect of the flow guide groove, slide into the reactioncavity from the opening and closing plate and react with chemical substances in the reaction cavity to absorb a large amount of heat, and then a cold source with the low temperature is formed in the internal space where the headlamp is located, and the formation of the cold source can further promote the water vapor to liquefy to form water drops, so that the water collection capacity in the headlamp is improved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an automobile headlight with good waterproof effect. Background technique [0002] With the advent of winter, the gradually widening temperature difference between day and night often causes the headlights to fog up, which affects the light transmittance of the car headlights, weakens the lighting effect at night, and poses a huge hidden danger to the safety of driving at night. In addition, the fogging of the headlights will easily cause the headlights to form astigmatism, which will not form a proper focus correctly, and will cause dazzling light pollution to vehicles in the opposite direction; and the relevant electrical components in the lights will also be corroded by water vapor, which will affect the use life. [0003] The causes of fogging in the headlights of automobiles can be roughly divided into three categories. First, moisture desorption caused by temperature difference, ...
