Self-feedback type electric folding bicycle

Abstract

The invention relates to a self-feedback type electric folding bicycle, comprising a U-shaped bicycle beam, a handlebar component, a front fork component, a rear fork component, a pedal plate component, a front wheel, a rear wheel, a saddle component and an internal battery, wherein the internal battery is arranged in an internal cavity of the bicycle beam; the front part and the rear part of the bicycle beam are provided with a forward turning joint and a backward turning joint respectively; after the front fork component is turned around the forward turning joint, the front wheel is caused to fall into a range surrounded by the bicycle beam; meanwhile, after a rear fork turns around the backward turning joint, the rear wheel falls into the surrounding range of the bicycle beam at the same time; a self-power-generation device is fixedly arranged on the rear fork component; during riding, the rear wheel drives the self-power-generation device to generate power; the generated electric energy is stored in a capacitor, i.e. in the capacitor on the battery periphery, through a wire; and the capacitor is connected with the battery in an electronic control way. With the adoption of the self-feedback type electric folding bicycle, the service time of the battery is improved through the self-feedback type power generation device; especially, such a bicycle is applicable for long-distance riding; and moreover, the structure is compact, and the shape is attractive.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to a self-feedback electric folding bicycle which is convenient to be folded and carried, and which can recover energy when the vehicle brakes or goes downhill. Background technique [0002] Electric vehicles take up a lot of space when parked here. Therefore, developing an electric vehicle that can fully reduce the total volume after being folded can make use of the box-type electric vehicle high-density three-dimensional parking device, making electric vehicles a priority for public transportation. The concept of green travel creates conditions. Especially in the context of urban traffic congestion and high oil prices, it is more and more necessary to use environmentally friendly transportation methods for work and travel. In order for users to use bicycles for transportation when the distance is long, it is usually On the basis of traditional bicycles, batteries and motors are ...

Problems solved by technology

[0004] There are also some solutions that choose wheels with a small diameter, which reduces the volume, but the wheels with a diameter that is too small have poor passability and reduce the comfort when riding.

Existing Chinese invention patent CN102180215A discloses a kind of 6 inches folding bicycle, comprises link mechanism, seat tube, saddle, rear fork, vehicle body front frame, front fork, handlebar, front wheel, rear wheel and driving mechanism, by using The link folding mechanism increases the folding speed. The five-way tube is used as the folding shaft to make the link folding mechanism more reasonable and compact, and the distance between the seat and the pedals is widened. The V-shaped folding handle and folding stem are adopted. The cooperation of the tube makes the bicycle fold smaller. Although this disclosed invention meets the requirement of folding the body smaller, it is not comfortable to ride in practice, and it does not have a power supply mechanism, and the diameter of the front and rear wheels is very small, which is uncomfortable Because the cycling distance is too long to meet the needs of modern cities
