Electric vehicle helmet What is the reason why the lens keeps sliding

1、 No need to remove the inner lens structure

First fold the inner lens, the inner lens will fold together with the foam layer, and then there will be a gap between the inner lens and the shell. Use 502 or glass glue directly and stick a little sponge or soft PU pad at the gap of the shell to prevent the inner lens from falling off automatically. Because sponge or other things are added to block the sliding exit of the inner lens, if you want to knock down the inner lens, you need to use force on the push rod of the inner lens.

2、 Remove endoscopic structure

Take out the whole tank first, and then take out the main body of the foam layer. Generally, the manufacturer will paste some glue on the top or around the main body of the foam layer to prevent the foam from shrinking due to heat, climate or humidity. So when you remove the foam layer, be careful.

After the above two steps are taken apart, the inner lens infrastructure will appear on the left and right sides of the inner lens. You can check to see which side is wrong, and then contact the manufacturer to give you which side. If there is no problem with the base, pull out the inner lens and check the two pins of the inner lens for damage.
