Frame assembly for foldable electric vehicle

Abstract

The invention discloses a frame assembly for a foldable electric vehicle. The frame assembly comprises a front triangular bracket assembly, a rear triangular bracket assembly and a saddle assembly, wherein a vehicle head frame, an upper cross beam, a lower cross beam and a supporting rod are arranged on the front triangular bracket assembly; one end of the upper cross beam and one end of the lower cross beam are both hinged on the vehicle head frame while the other ends are hinged at the front end of the saddle assembly; one end of the supporting rod is hinged on the lower cross beam; the other end of the supporting rod is in sliding connection with the upper cross beam; the other end of a connecting rod is hinged on the rear triangular bracket assembly; the rear triangular bracket assembly is hinged at the rear end of the saddle assembly; the saddle assembly comprises a seat upright pipe, a seat upright pipe sleeve and a shell; the seat upright pipe is inserted in the seat upright pipe sleeve in a sliding form; the seat upright pipe sleeve is fixedly connected to the shell; the shell has an accommodating slot; a front end part of the rear triangular bracket assembly is located in the accommodating slot and is propped against the bottom of the accommodating slot; and the seat upright pipe is tightly propped against the front end part of the rear triangular bracket assembly in the accommodating slot. By adopting the frame assembly, the foldable electric vehicle can be smoothly and quickly folded and can be more conveniently locked.

Description

technical field [0001] The invention relates to an electric vehicle component, in particular to a vehicle frame assembly of a folding electric vehicle. Background technique [0002] The vehicle frame assembly of traditional folding electric vehicle all comprises front tripod assembly, rear tripod assembly and vehicle seat assembly, and front tripod assembly and rear tripod assembly are all hinged on the vehicle seat assembly, and The front tripod assembly and the rear tripod assembly can be folded. Folding is divided into two steps. Fold the front tripod assembly first, and then fold the rear tripod assembly. This kind of folding structure has the disadvantages of slow folding speed and incomplete folding. Disadvantage; and the locking method that the traditional folding electric vehicle adopts is very complicated when in use, and the seat riser and the rear tripod are locked by a very complicated locking method, so as to ensure locking when driving.
