TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile body structure, in particular to a hard-top electric convertible mechanism and a convertible. BACKGROUND

[0002] With the rapid development of the automobile industry, the automobile not only bears the function of transportation, but also becomes a carrier to show personal taste and lifestyle. Convertibles gradually enter people's lives. The existing convertibles are divided into hard-top and soft-top. The soft-top convertible has better foldability, but the soft-top material is relatively soft and the structural strength is weak. The structure of the hard-top convertible is more stable.

[0003] At present, the hard-top convertible is folded and stored in the trunk in a translational or rotational folding manner. The trunk part often needs to be opened with a hydraulic rod. The driving distance of the hydraulic rod is relatively long, which causes the movement of the trunk to lag behind, the opening and closing speed to be slow, and the folding efficiency of the convertible to be reduced.
