Description

technical field

[0001] The invention relates to a cabin door structure, in particular to a front flap cabin door structure of a passenger car. Background technique

[0002] Hybrid buses operating in the market are 90% identical in terms of design. Its design structure is that the gas cylinder is placed on the side of the middle area. Due to the existence of water tanks on both sides of the rear area, generally in the design, if the battery is placed in the rear hatch of the rear wheel, it will not meet the required power. Therefore, most The manufacturer will place the battery behind the rear passenger area, and design a compartment door in the middle. However, the traditional front flap hatch structure generally requires manual positioning when it is turned over, which is laborious and the degree of automation is not high.

[0003] Therefore be badly in need of a kind of simple in structure, can realize opening the front flap cabin door structure of the passenger car of se...
