Foldable electric vehicle and its folding connecting device

Abstract

The invention discloses a folding connection device, which comprises a bracket, two clutch pin shafts arranged side by side on the bracket, and two pivot members pivotably connected to the two clutch pin shafts respectively. The clutch pin is axially movably connected with the bracket, and the clutch pin is provided with a pivot limiting part that restricts the pivoting of the pivoting member relative to the bracket. One side of the bracket and the pivoting member is respectively provided with a pivoting The limit part is a limit hole for limit fit, and the clutch pin is clutched and switched between pivotable and fixed relative to the bracket. The beneficial effect of the folding connection device is that the folding connection device adopts a pin shaft with a clutch function, which simplifies the structure. The invention also discloses a foldable electric vehicle adopting the above-mentioned folding connection device, which includes a vehicle frame. The vehicle frame comprises a first split body and a second split body respectively connected to the above two pivoting parts. After the electric bike is folded, , the first split body is aligned with the second split body, and the space occupied by the folded frame is halved when unfolded.

Description

technical field [0001] The invention relates to a walking-replacing tool and its accessories, in particular to a foldable electric vehicle and a folding connection device thereof. Background technique [0002] With the development of low-carbon economy, my country's electric vehicle industry is developing at a high speed. At present, there are many types of electric vehicles with different structures, but generally there are problems such as large body, heavy weight, and inconvenient storage, so folding electric vehicles have emerged as the times require. However, for folding electric vehicles, the placement of the folded wheels is usually a difficult point in design. Therefore, the position of the wheels in the folded position of the car body is one of the focuses of research and development. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a folding connection device that facilitates the folding and use of the...
