Problems solved by technology

Although these devices can solve the problem of using pedal power to drive the rear wheels to rotate and walk, but because they rely on gear sets to change speed, the structure is complicated and heavy; the installation accuracy is high; and the pedals can only be returned by springs.
Patents ZL02234418.7, ZL200320105635.5 and invention patent application number are 200310105597.8 documents all disclose or substantially disclose a kind of scooter device that utilizes pedal (or pedal connecting rod) to pull chain, and chain drives gear set variable speed transmission again, this type of device The spring return mechanism is also used, and when two pedals are used, the interactive return between the two pedals cannot be realized.

Abstract

A manual scooter is disclosed, which comprises bracket, front wheel and back wheel, drive set of back wheel, two pedals and their power drive gear. The pedals movably connect the bracket to conduct alternated up and down interaction. In said back wheel drive set are fitted with two sets of cord wheel coaxial with the back wheel and two single-direction mechanisms connected respectively to corresponding cord wheel. The two single-direction mechanisms are in drive connection with the back wheel. The said pedal power drive gear is a pull-type drive gear that comprises two guy cables in drive connection respectively with corresponding cord wheel. In the power drive gear can be fitted with pulley group or large small cord wheel set speed-changing mechanism.

Description

Technical field: [0001] The invention relates to a scooter that relies on human body weight or pedaling force, in particular to a scooter that pulls the double one-way mechanism to drive the rear wheel to walk by the way that the up and down of the two pedals are mutually linked, and realizes the automatic return of the pedal and the cable Scooter device. Background technique: [0002] Present commercially available two to three-wheel scooter mainly utilizes inertial walking after obtaining power by a pedal of the people, and it needs one foot to pedal frequently, which is not very convenient. In the published patent documents, patents ZL01222047.7 and ZL02202242.2 disclose a scooter device that utilizes a pedal direct transmission link (rack) to drive a gear set to change speed. Although these devices can solve the problem of utilizing pedal power to drive the rear wheels to rotate and walk, because they are geared to change speed, the structure is complicated and heavy; t...
