Description

technical field [0001] The invention relates to the technical field of doors of automobile compartments, in particular to a door system and a vehicle. Background technique [0002] With the development of social economy, fuel economy regulations are currently being tightened, but battery technology is not advanced and mature enough, and battery prices remain high. Lightweight has become one of the important development trends of traditional internal combustion engine vehicles and new energy vehicles. Lightweight vehicles are to reduce the curb weight of vehicles as much as possible under the premise of ensuring the strength and safety performance of vehicles, so as to improve the dynamic performance of vehicles. Reduce fuel consumption and reduce exhaust pollution. At present, automobile lightweight has become an effective measure to reduce automobile emissions and improve combustion efficiency. [0003] At present, the rear split doors of commercial vehicles are usually s...

AI Technical Summary

Problems solved by technology

[0003] At present, the rear split doors of commercial vehicles are usually steel stamping structures. Although the shape can meet the design requirements, due to the high density of steel plates, the weight of the entire door is relatively heavy, which is prone to quality problems such as door sinking.

[0004] Moreover, usually the rear split door of a commercial vehicle can be opened by 90 degrees, but it is restricted by the limit mechanism and cannot continue to open a larger opening.
