Description

Folding locking mechanism of electric vehicle frame Technical Field The utility model relates to the field of folding of frames of electric vehicles, in particular to a folding locking mechanism of a frame of an electric vehicle. Background The electric vehicle is accepted by the public more and more with the advantages of convenience, green environmental protection and the like. The electric vehicle is based on the structure of the existing bicycle to reform the electric vehicle, and the electric vehicle can be driven by electric energy to run rapidly by adding a battery, a driving system and an electric control system, so-called an electric vehicle frame is an integral frame used by the electric vehicle; The utility model provides a light-duty electric motor car, is CN207060274U to prior art patent number, discloses a light-duty electric motor car, including electric motor car frame main part, electric motor car frame main part comprises front end frame and the rear end frame that sets up in this electric motor car frame main part side of setting in this electric motor car frame main part one side, the side-mounting of handheld frame has the seat package, just the seat package embedding sets up in the rear end frame, the support kun is installed to the bottom of seat package, just support kun is closely welded with the rear end frame, a plurality of evenly distributed's rear wheel connects the frame in the bottom of rear end frame, this kind of light-duty electric motor car frame is with controller, burglar alarm, lithium cell and converter installation in front portion of front end frame to cover with the theftproof apron, be favorable to improving light-duty electric motor car frame's theftproof performance, the controller is installed in L pipe department, can carry out the forced air cooling heat dissipation for the controller in the electric motor car advancing the in-process, and can effectual waterproof, reduces the fault rate of controller.
