Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of truck side skirts, and particularly relates to a side skirt electric turnover system. BACKGROUND

[0002] As a kind of dynamics kit, the truck side skirt can effectively reduce the air resistance of the truck during driving, which is conducive to reducing fuel consumption. With the implementation of the new national standard, long-nose trucks gradually appear on the market. Compared with traditional flat-nose trucks, long-nose trucks need to install side skirts on both sides of the frame due to their unique structure and high chassis. Compared with small cars, the running conditions of trucks are more severe, the failure rate is higher, and the engine and transmission are arranged below the cab. Once a fault occurs, the side skirt needs to be manually disassembled. Therefore, the traditional manual turnover side skirt method cannot meet the convenience of customer use, and the electric turnover system of the side skirt gradually becomes a trend. SUMMARY
