Abstract

The invention discloses an electric folding tricycle which comprises a frame assembly, a handlebar, a saddle, a front wheel and two rear wheels, wherein the frame assembly comprises a front frame assembly and a rear frame assembly; the rear frame assembly comprises a frame rear beam; symmetrically hinged parallelogram-shaped mechanisms are arranged on two sides of the frame rear beam; each of the two rear wheels is arranged on one rod piece of each of the two parallelogram-shaped mechanisms; a sliding rear beam is arranged at the rear end of the frame rear beam, and two crank block mechanisms symmetric about the frame rear beam are formed; after being locked by a locking bolt, the whole rear frame assembly is fixed; the front frame assembly comprises a frame front beam; the frame front beam is connected with the frame rear beam through a connection hinge; a frame front pipe is hinged to the frame front beam; a frame front pipe lock bar is connected between the frame front beam and the frame front pipe; when the electric folding tricycle is needed to be folded, relevant connection pieces are removed or loosened to draw and fold the front frame assembly and the rear frame assembly; and after being folded, the electric folding tricycle has a regular shape and is extremely small in size, so that the electric folding tricycle is convenient to carry and store.

Description

technical field [0001] The invention relates to a tricycle, in particular to an electric folding tricycle. Background technique [0002] In recent years, due to the increasingly serious problems of global environmental pollution, resource shortage, urban traffic congestion, and social aging, tricycles are favored by people, especially old people, for their environmental protection, fitness, safety, stability and convenience. But at the same time, a series of problems have emerged, such as insufficient parking area, parking on the sidewalk, and easy theft. In the face of today's congested traffic conditions and environmental protection and convenience, there is an urgent need for a lightweight and portable vehicle to serve people's daily life, which brings great room for development of folding bikes. [0003] Tricycles are more and more popular with the elderly because of their safe and stable riding. Most existing tricycles cannot be folded, take up a lot of space, and are ...
