Abstract

The invention provides a portable electric vehicle linkage folding mechanism. In the folding mode, a linkage mode is adopted, that is, a plurality of folding steps are achieved through a simple action by a single hand on the premise that a handlebar part is not replaced, so that an ideal folding effect is achieved on the premise of greatly improving the folding efficiency. According to the portable electric vehicle linkage folding mechanism, only one folding action needs to be done, synchronous automatic folding of the other folding steps is achieved through a mechanical linkage device so that the folding efficiency can be improved, and one-second folding is truly achieved.
