Title:
NOVEL QUICK-FOLDING ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2016/173560
Kind Code:
A3
Abstract:
A novel quick-folding electric vehicle, comprising: a main beam (1), a rear wheel (2), a crossbeam (3), a support (4), and a seat pad (5) capable of moving back and forth. A bolt (7) is arranged at the intersection point of a lower end of the support and the main beam, the lower end of the support is provided with a supporting post (8), the support and the supporting post are rotatably arranged around the bolt, an angle less than 180 degrees is formed between the supporting post and the support, and a lower end of the supporting post is provided with drag wheels (9). During folding, the seat pad slides forwards from a rear portion of the crossbeam, the seat pad drives the support and the supporting post to rotate around the bolt in an anticlockwise manner, the drag wheels move downwards and backwards and gradually come into contact with the ground, and after the drag wheels have come into contact with the ground, the rear wheel leaves the ground, the seat pad moves to a front portion of the crossbeam, the folding action is complete, and the vehicle enters a state for being dragged or lying flat. During dragging, the drag wheels are located at a central rear-biased position of a vehicle body, and when a person is standing, the vehicle body is tilted, the centre of gravity naturally moves backwards, the pressure produced by the vehicle body on the person is relatively small, and effort is saved during dragging. During folding, the seat pad moves forwards and does not move backwards, saving space at a rear portion of the vehicle body. When the vehicle is folded and lies flat, the drag wheels are in contact with the ground, and it is difficult for the vehicle body to be toppled over.
