Car sunroof rain equipment - how to conduct waterproof test

The car sunroof is installed on the roof, which can effectively circulate air in the car and increase the intake of fresh air. At the same time, the car sunroof can also broaden the field of vision and other needs. It is especially popular among consumers in the domestic market.

Car sunroofs can be roughly divided into: sliding type, hidden type, hidden inside and outside flip type, panoramic type and curtain type, etc. They are mainly installed on commercial SUVs, sedans and other models.

Product structure, material and power

The car sunroof shower equipment is redesigned based on the equipment design that the customer has been using for many years.

The main frame is made of square tube 100mm*100mm or 80mm*80mm stainless steel material (grade SUS304), and is connected to the ground with expansion bolts (if conditions permit, pre-buried bolts in the ground can increase strength). Since it is installed on-site, the main frame splicing structure is connected with bolts.

The shower nozzles and pipes are installed on the shower tray bracket. The double-layer equipment has one layer of nozzles arranged on the upper and lower sides. The shower tray bracket is welded and spliced ​​with 304 stainless steel profiles. The spray system and shower tray bracket are hoisted on the main frame by a wire rope winch.

The shower tray and the main water pipe are connected by a metal hose (or rubber hose). The shower tray can be raised or lowered by 500mm and the angle can be adjusted by 20 degrees.
