Foldable foot-driven draw-bar box

Abstract

The invention relates to a draw-bar box, in particular to a foldable foot-driven draw-bar box. The foldable foot-driven draw-bar box comprises a handlebar assembly, a steering wheel, a folding joint,a riding pedal, a gear transmission gearbox, a spline sliding clutch, a main frame, a subframe, a transmission shaft, a support groove, a rear wheel and a rear gear transmission system, wherein the steering wheel is arranged at the bottom of a handlebar; the handlebar is hinged to one end of the subframe through the folding joint; the other end of the subframe is hinged to the main frame; the riding pedal is hinged to the gear transmission gearbox; the gear transmission gearbox is connected with or disconnected from the transmission shaft through the spline sliding clutch; the transmission shaft is connected with the rear gear transmission system; the rear wheel is connected with the rear gear transmission system; the support groove is formed in the main frame; and the handlebar assembly,the subframe and the main frame are folded in three stages, and then put into the support groove. Through three-section folding, the draw-bar box is compact and small after folding; the complete switching between foot driving and hand dragging can be realized; and the steering is convenient and flexible.

Description

technical field [0001] The invention relates to a trolley case, in particular to a foldable trolley case for pedaling. Background technique [0002] With the acceleration of the pace of life, people are increasingly pursuing the convenience and speed of travel, but it is very inconvenient to travel with heavy objects. When the passenger travels, the suitcase is completely dragged by the passenger on foot. When carrying a large amount of articles, it is a very big burden for the passenger, which makes the passenger inconvenient to move. The walking drag that traditional suitcases rely on is relatively slow and will take a certain amount of time, making it impossible for people to arrive at the target location in time. Though bicycle has load function but because of its volume is too large, can't take on the means of transportation such as train plane, and because its load capacity is less, so be difficult to use in long-distance or mid-distance travel.

AI Technical Summary

Problems solved by technology

However, there are following deficiencies: 1. It does not have a folding function, and the volume is large and inconvenient to use

2. The clutch between the pedal transmission shaft and the rear wheel drive shaft cannot be realized, the pedal driving and the hand towing cannot be completely separated, and the complete switch between the pedal driving and the hand towing cannot be realized

3. Rear wheel steering is inconvenient
