Sealing connection mechanism for electric vehicle headlamp

Abstract

The invention relates to the related technical field of electric vehicle headlamps, and discloses a sealing connection mechanism for an electric vehicle headlamp. The mechanism comprises a frame and alampshade, an annular embedding groove matched with the lampshade is formed in the right side port of the frame, an annular mounting groove is formed in the annular inner side wall of the annular embedding groove, an annular bag cushion matched with the inner side wall of the annular mounting groove is mounted on the inner side of the annular mounting groove, an air guide connector pipe of the annular bag cushion penetrates through the frame and extends to the inner side of the frame, and an airtight core is mounted at the tail end of the air guide connector pipe of the annular bag cushion. According to the sealing connection mechanism for an electric vehicle headlamp, a matched connection gap between the lampshade and the frame can be effectively filled and sealed, the sealing connectionmechanism is different from a traditional structural mode of pressing sealing by a sealing strip, the lampshade and the frame can be adjusted and sealed many times, whether a sealing cavity is in a completely-sealed using state or not can be judged, demisting treatment is carried out while the lampshade is free of disassembly, and operation and maintenance by related operators are facilitated.

Description

technical field [0001] The invention relates to the related technical field of electric vehicle headlights, in particular to a sealed connection mechanism for electric vehicle headlights. Background technique [0002] Battery car is also called electric car. It is a pure electric motor vehicle driven by a battery (battery) and driven by a motor (DC, AC, series excitation, separate excitation). In recent years, it has been widely popularized in our country. The headlight mechanism on electric vehicles is generally connected to the car body through a clamping method, and a sealing strip is bonded to the clamping structure to ensure that the lampshade and the car body At the same time, it is necessary to do waterproof treatment on the inside of the lampshade to prevent the sealed structure in the lampshade from being immersed in water to produce water mist, which will affect the lighting sight of the rider driving at night. In the prior art, water mist is generated inside the l...
