Description

Technical Field

[0001] The utility model belongs to the technical field of clearance lamps, and more specifically, particularly relates to a waterproof and anti-fog structure of a clearance lamp. Background Art

[0002] Position lights are usually located at the four corners of a vehicle, two at the front and two at the rear, to illuminate the side of the vehicle. Such lights are generally installed at the edge of the top of the vehicle, which can indicate both the height and width of the vehicle. Safety standards stipulate that vehicles with a height of more than three meters must be equipped with position lights. Position lights are usually brighter than width lights and can better illuminate the side of the vehicle. The presence of water mist inside the position lights is an abnormal phenomenon, which usually means that there is a problem with the sealing of the position lights, causing moisture to enter the lampshade. The existing waterproof and anti-fog structure of position lights is waterproof and anti-fog through sealing strips. Aging of the sealing strips or loosening of the sealing strips due to vibration may cause water to enter the position lights and cause fogging. Therefore, a waterproof and anti-fog structure of position lights is proposed. Utility Model Content

Aging of the sealing strip or loosening of the sealing strip due to vibration may cause water to enter the inside of the position marker light and fogging may occur.

[0024] When the heating wire 12 is not started, the first bimetallic strip 14 is higher than the second bimetallic strip 15. The first bimetallic strip 14 lifts the first baffle 9 through the first connecting piece 16, thereby blocking the inside of the air inlet pipe 7. The second bimetallic strip 15 pulls the second baffle 11 through the second connecting piece 17, so that the inside of the air inlet pipe 7 is connected with the inside of the equipment box 3 and the outer shell 1. The moisture in the outer shell 1 is absorbed by the moisture absorption block 13. After the moisture absorption block 13 fails, the heating wire 12 is started regularly to heat the moisture absorption block 13. Since the moisture absorption block 13 is a graphene desiccant, it can be reused after heating. At the same time, the first bimetallic strip 14 and the second bimetallic strip 15 are deformed by heat. Since the arrangement structure of the first bimetallic strip 14 and the second bimetallic strip 15 is opposite, the first bimetallic strip 14 is lower than the second bimetallic strip 15. The first bimetallic strip 14 is pulled by the first connecting piece 16. The first baffle 9 makes the inside of the exhaust pipe 5 communicate with the inside of the equipment box 3 and the exhaust hole 2. The second bimetallic strip 15 lifts the second baffle 11 through the second connecting piece 17, so that the air inlet pipe 7 is blocked. The moisture generated by the heating of the hygroscopic block 13 is discharged to the outside through the exhaust pipe 5 and the exhaust hole 2 to prevent the moisture from flowing back to the inside of the outer shell 1. After the hygroscopic block 13 is dried, the heating wire 12 stops heating, and the first bimetallic strip 14 and the second bimetallic strip 15 return to their original state, so that the first baffle 9 and the second baffle 11 return to their original position, thereby opening the air inlet pipe 7 and closing the exhaust pipe 5. Through the above process, the water vapor of the position marker lamp can be automatically cleared, which plays a role in waterproofing and fogging, and solves the problem of the existing waterproofing and fogging structure of the position marker lamp. The waterproofing and fogging are performed by the sealing strip. The aging of the sealing strip or the loosening of the sealing strip due to vibration may cause water to enter the interior of the position marker lamp and fogging.

[0025] Specific usage and function of this embodiment: When the electric heating wire 12 is not started, the first bimetallic strip 14 is higher than the second bimetallic strip 15. The first bimetallic strip 14 lifts the first baffle 9 through the first connecting piece 16, thereby blocking the inside of the air intake pipe 7. The second bimetallic strip 15 pulls the second baffle 11 through the second connecting piece 17, so that the inside of the air intake pipe 7 is connected with the inside of the equipment box 3 and the outer shell 1. The moisture in the outer shell 1 is absorbed by the moisture absorption block 13. After the moisture absorption block 13 fails, the electric heating wire 12 is started regularly to heat the moisture absorption block 13. Since the moisture absorption block 13 is a graphene desiccant, it can be reused after heating. At the same time, the first bimetallic strip 14 and the second bimetallic strip 15 are deformed by heat. Since the first bimetallic strip The arrangement structure of the first bimetallic strip 14 is opposite to that of the second bimetallic strip 15, so that the first bimetallic strip 14 is lower than the second bimetallic strip 15. The first bimetallic strip 14 pulls the first baffle 9 through the first connecting piece 16, so that the interior of the exhaust pipe 5 is connected with the interior of the equipment box 3 and the exhaust hole 2. The second bimetallic strip 15 lifts the second baffle 11 through the second connecting piece 17, so that the intake pipe 7 is blocked, and the moisture generated by the heating of the desiccant block 13 is discharged to the outside through the exhaust pipe 5 and the exhaust hole 2 to prevent the moisture from flowing back to the interior of the outer shell 1. After the desiccant block 13 is dried, the heating wire 12 stops heating, and the first bimetallic strip 14 and the second bimetallic strip 15 return to their original state, so that the first baffle 9 and the second baffle 11 return to their original positions, thereby opening the intake pipe 7 and closing the exhaust pipe 5.
