Description

[0001] The present application belongs to the technical field of automobile parts, and particularly relates to a scissor door hinge system and a vehicle comprising the same. BACKGROUND

[0002] With the progress of automobile technology, the appearance of automobiles is constantly updated and iterated, becoming more and more fashionable and high-end. For example, the application of scissor doors makes the appearance of automobiles more attractive and high-end.

[0003] Some existing scissor door structures mainly include a hinge, an extension link, and a spring push rod. The hinge plays a crucial role in the opening height, opening degree, and stability of the door, and the quality of the hinge directly determines the opening / closing action of the door.

[0004] The opening mode of some existing scissor doors, such as the Chinese invention patent with publication number CN113266223A, generally requires opening to the maximum degree first, and then turning upward to the maximum position. The opening or closing action of the door needs to be implemented in two steps, and the door can only be opened or closed in a single direction at each step. This opening mode has poor user experience, the movement is not very smooth, and the human-machine operability when opening or closing the door is also poor.
