Abstract

A foldable trishaw comprises a front fork stand pipe, a saddle rack, a rear wheel rack, a front wheel, rear wheels and a transmission mechanism, wherein the lower part of the rear end of a beam front pipe and the lower part of the front end of a beam middle pipe are connected with each other via a beam-to-beam hinge pair and are fixed through elastic bolts of hinges; the upper part of the front end of the beam front pipe is connected with the front fork stand pipe through a front fork stand pipe hinge pin shaft; the rear end of the beam middle pipe is fixedly connected with the rear wheel rack; an elastic shock-absorbing strip spring and the lower end of the saddle rack are respectively fixed on the beam middle pipe and the rear wheel rack; the upper end of the saddle rack is movably connected with the upper end of the elastic shock-absorbing strip spring by an elastic bolt; and a left rear wheel shaft and a right rear wheel shaft are fixed on the left side and the right side of the rear wheel rack through a shaft support. The foldable trishaw has the characteristics of simple structure, convenience in use, safety and small occupied space. Because the rear wheels have double-axle structures, a sufficient space is reserved between the two rear wheels, and a front fork and the front wheel can be folded in the space. After the front fork and the front wheel are folded, the foldable trishaw can be used as a small trailer, and is particularly suitable to be used as a body-building tool or a traffic tool for middle aged and elderly people.

Description

The foldable pedal three-wheel car

Technical field

The present invention relates to a kind of foldable pedal three-wheel car.

Background technology

The trishaw that an existing front-wheel two trailing wheels form, since bulky, can't fold, be not suitable for middle-aged and old fitness and ride use instead of walk.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structure, easy to use, little, riding safety that takes up room, the foldable pedal three-wheel car that is applicable to middle-aged and old body building and rides instead of walk.

Foldable pedal three-wheel car of the present invention, comprise vertical tube of front fork, Pillar for saddle, rear wheel frame, front fork, front-wheel, trailing wheel and transmission device, between vertical tube of front fork and the rear wheel frame by managing before the car beam, pipe is connected as a single entity in the car beam, before the car beam in the rear end of pipe and the car beam front end of pipe link to each other with hinges between beam, and fix by the hinges resilient latches, in the car beam captive joint with rear wheel frame in the rear end of pipe, the lower end of elastic shock attenuation bar spring and Pillar for saddle is separately fixed in the car beam on pipe and the rear wheel frame, the Pillar for saddle upper end is connected with elastic shock attenuation bar spring movable upper end with resilient latches, also be provided with pipe beam locking plate and Pillar for saddle locking plate in the car beam on the pipe, the left side of rear wheel frame, axle bearing support fixedly left rear axle and right back axle, left rear axle are passed through in right both sides, right back axle respectively with left rear wheel, off hind wheel links to each other.

Foldable pedal three-wheel car of the present invention, folding process is: the resilient latches of vertical tube of front fork hinge is pulled open, making vertical tube of front fork manage hinge pin before the car beam rotates, pipe is close together with vertical tube of front fork before the car beam, hinge elastic force latch with pipe before pipe and the car beam in the car beam pulls open again, pipe is managed the hinge pin rotation before making the car beam in the car beam, before the car beam, middle pipe folding together, Pillar for saddle upper end resilient latches is pulled open, untie elastic shock attenuation bar spring, make in Pillar for saddle and the car beam and manage folding together, meanwhile, pipe beam locking plate in the car beam on the pipe just in time is in the position of vertical tube of front fork hinge elastic force latch, and the Pillar for saddle locking plate in the car beam on the pipe is in resilient latches position, Pillar for saddle upper end, in the resilient latches Inserting Tube beam locking plate with the vertical tube of front fork hinge, pipe is fixing with the front pipe of car beam in the car beam, in the locking plate on the pipe in the resilient latches insertion car beam of Pillar for saddle upper end, pipe is fixing in Pillar for saddle and the car beam, thereby finishes the folding of whole body part.

That foldable pedal three-wheel car of the present invention has is simple in structure, safe and convenient to use, little characteristics take up room, because trailing wheel adopts cross-compound arrangement, so that between two trailing wheels, leave enough spaces for front fork and front-wheel folding, can work as towing dolly after folding and use the usefulness that is particularly suitable for middle-aged and old body building and rides instead of walk.
