Embodiment Construction

[0022] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0023] Such as figure 1 , figure 2 Shown, a pedal-type stepping bicycle, a pendulum scooter that realizes power transmission and acceleration by human body weight or pedaling force, it includes a front wheel component, a rear wheel component and a vehicle frame component.

[0024] The front wheel components mainly lead and control the driving direction, specifically including the front wheel 10 that dominates the driving direction, the handlebar 3 that controls the driving direction, the brake handlebar 2 that controls the braking or deceleration of the vehicle, the fixed front wheel 10 and the articulated handlebar riser The front fork tube 4 of 1 is hinged with the front fork tube 4 and the handlebar standpipe 1 connected to the handlebar 3.

[0025] The vehicle frame part is mainly...

Abstract

The invention discloses a pedal-type foot step bicycle, which includes a breeches pipe of a front wheel, a riser of a handlebar and a left and a right pedals as well as connecting rod and crank mechanisms which are connected with the left and the right pedals and a speed change mechanism for a sprocket connected with the two groups of connecting rod and crank mechanisms. The bicycle has small size, light weight, stable performance, simple manufacturing process and low manufacture cost and is applicable of being produced in mass. The bicycle is an ideal small-sized sports tool which combines body-building, entertainment, leisure and riding instead of walking together.

Description

technical field [0001] The invention relates to a pedal type stepping bicycle. Background technique [0002] The scooter power transmission device generally all adopts rack, chain and gear transmission at present. The speed change mechanism generally adopts gears and sprockets to accelerate. The structures of these mechanisms are complicated and cumbersome, and the manufacturing and installation precision is high, and the manufacturing cost is high, so they are not suitable for batch production and product commercialization. [0003] Moreover, its two rear wheels of various scooters are all drive wheels at present, so the speed difference of the two rear wheels cannot be automatically adjusted when turning, so the front wheels and handlebars are not controlled smoothly when turning, and the rear wheels are not facing the ground simultaneously. Pure rolling, there is sliding phenomenon, easy to wear tires. [0004] Moreover, the current transmission form of scooters is gen...
