Problems solved by technology

For example, when turning at a high speed, the tricycle is prone to rollover, and the riding experience is poor; tricycles generally cannot be folded and take up a lot of space; Less comfortable ride
There is also an important defect that existing tricycles cannot form two-wheeled vehicles through deformation, and cannot be operated as conveniently and flexibly as two-wheeled vehicles

Abstract

The invention discloses a foldable tricycle which comprises a frame and wheels. The frame comprises a first supporting rod, a main beam and two second supporting rods which are sequentially connected,the first supporting rod is hinged to one end of the main beam, the second supporting rods are hinged to the other end of the main beam through a universal joint, a first limit device for limiting the universal joint to rotate is arranged on the universal joint, the first limit device is used for controlling the universal joint to be in a movable state or a locking state, the second supporting rods, the main beam and the first supporting rod are sequentially connected to form a Y-shaped or T-shaped structure, and the wheels are mounted at free ends of the first supporting rod and the second supporting rods. The foldable tricycle has the advantages that riding is comfortable, and the tricycle is high in safety and foldable and can be changed into a two-wheeler.

Description

technical field [0001] The invention relates to the field of tricycles, in particular to a foldable tricycle. Background technique [0002] Tricycles have special applications in many fields, such as children toddler, the disabled, the elderly as a scooter, etc. The tricycle has the advantages of good stability, simple manipulation and wide application range because it includes three wheels. However, precisely because the tricycle has three wheels, it also brings some technical problems. For example, when turning at a high speed, the tricycle is prone to rollover, and the riding experience is poor; tricycles generally cannot be folded and take up a lot of space; The ride comfort is low. Another important defect is that existing tricycles cannot form two-wheeled vehicles through deformation, and cannot be as convenient and flexible as two-wheeled vehicles. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the purpose of the prese...
