[0041] refer to figure 1 , an anti-fogging device 100 for vehicle lights, wherein the anti-fogging device 100 includes a container 10, the container 10 has a first air hole 11 and a second air hole 12 for circulating air, the air can flow from the first air hole 11 1. One of the second air holes 12 flows into the container 10 and flows out of the container 10 through the other air hole.

[0042] refer to figure 2 , the anti-fogging device 100 further includes a cold source 20 , and the cold source 20 is arranged in the container 10 for cooling and dehumidifying the air flowing through the container 10 . Specifically, when the air flows through the container 10, the cold source 20 can cool the air, and when the temperature of the air is lowered, the water vapor mixed in the air can be condensed into dew, thereby achieving the technical effect of cooling and dehumidification.

[0043] The anti-fogging device 100 is installed on the vehicle lamp so that the container 10 commun...

[0056] refer to image 3 , this embodiment also provides a vehicle light 200, wherein the vehicle light 200 includes a lamp holder 201, a light-emitting part 202 is arranged inside the lamp holder 201, and the lamp holder 201 has a light distribution mirror 203 for emitting light. The light mirror 203 is oppositely arranged, so that the light emitting component 202 can directly emit light to the light distribution mirror 203 and pass through the light distribution mirror 203 to provide illumination. The lamp holder 201 also has a ventilation hole 204 , the ventilation hole 204 allows the air inside the lamp holder 201 to circulate with the outside air, and is used to balance the air pressure inside and outside the vehicle lamp 200 .

[0057] In this embodiment, the vehicle lamp 200 further includes an anti-fogging device 100 , one of the first air hole 11 and the second air hole 12 of the container 10 communicates with the air hole 204 , and the other communicates with the out...

[0070] In the second embodiment, the balance of air pressure inside and outside the lamp holder 201 is achieved through the vent hole 204 and the vent pipe 205 to achieve air flow. When the air inside the lamp holder 201 flows to the outside through the vent hole 204 and the vent pipe 205 , the higher temperature inside air will take away the cold energy of the cold source 20 , which is not conducive to cooling the outside air when it enters the inside of the lamp holder 201 .

[0071] refer to Figure 4 , in this embodiment, the air vent includes an air inlet 204a and an air outlet 204b, and the air vent includes an air inlet 205a and an air outlet 205b; the air inlet 205a communicates with the air inlet 204a, and the air outlet 205b communicates with the air outlet 204b , the anti-fogging device 100 is fixedly arranged on the air intake pipeline 205a. Specifically, the air intake line 205a is provided with an air intake one-way valve aa, and the air outlet line 205b is prov...

Abstract

The invention discloses a fogging prevention device, an automobile lamp, an automobile and a fogging prevention control method. The fogging prevention device comprises a container and a cold source, the container is provided with a first air hole and a second air hole which are used for circulating air, and the cold source is arranged in the container and used for reducing temperature and removingdampness for the air flowing through the container and can cools the air flowing through the container. When the temperature of the air is reduced, vapor mixed in the air is condensed into dew to beseparated out as the temperature is reduced, so that dehumidification can be achieved. The fogging prevention device is mounted to the automobile lamp, so that the container is communicated with the inside of the automobile lamp, the air entering the inside of the automobile lamp is relatively dry, humidity in the automobile lamp cannot be excessive, and fogging of the automobile lamp can be prevented.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an anti-fogging device, a vehicle lamp, an automobile and an anti-fogging control method. Background technique [0002] The automobile lamp includes a lamp holder and a light-emitting part arranged inside the lamp holder, the light-emitting part can emit light for realizing illumination when the car is running. When the lights are turned on, the light-emitting components emit heat, which heats up the air inside the lamp holder and increases the air pressure; when the lights are turned off, the air inside the lamp holder cools down and reduces the air pressure. [0003] In order to balance the air pressure inside and outside the lamp holder and prevent the seal failure of the lamp holder, in the prior art, vent holes are usually artificially provided on the lamp holder, so that the vent holes communicate with the inside of the lamp holder and the outside atmospheric pressure. ...
