Electric bicycle for physical training fitness

Abstract

The invention relates to the technical field of fitness equipment, and discloses an electric bicycle for physical training fitness. The electric bicycle for physical training fitness comprises chain wheels, wherein a chain is movably mounted on the chain wheels; chain pins are fixedly mounted on the chain; each chain pin is located between every two adjacent wheel teeth of each chain wheel; and sliding chutes are formed in the wheel teeth of the chain wheels. According to the electric bicycle for physical training fitness provided by the invention, through the arrangement of push plates and the sliding chutes, when the chain pins make contact with the push plates on the wheel teeth of the chain wheels, the push plates can be pushed to move rightwards, and then hard collision between the chain pins and the wheel teeth of the chain wheels is converted into elastic collision, so that friction loss between the chain pins and the wheel teeth of the chain wheels is reduced, and the situation that due to abrasion between the wheel teeth of the chain wheels and the chain pins, clamping is not tight, teeth jumping occurs, and finally the transmission efficiency of a chain transmission mechanism is affected is avoided; and meanwhile, the push plates move rightwards, then the surfaces of the push plates and the side walls of the sliding chutes jointly form clamping grooves, and the clamping grooves are used for clamping the chain pins pushing the push plates, so that the situation that the transmission efficiency of the chain mechanism is affected due to the fact that the wheel teeth of the chain wheels and the chain pins are not tightly clamped is avoided.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to an electric bicycle for physical training and fitness. Background technique [0002] Electric bicycles for sports training and fitness are also called spinning bicycles. It is a kind of indoor fitness equipment. It has a similar structure to bicycles, but it overcomes all the shortcomings of bicycles when they are driven outdoors, thus making spinning bicycles more safe. . [0003] Existing spinning bicycles are similar to bicycles when in use. People step on the pedals, and then drive the counterweight flywheel to rotate through the chain transmission mechanism connected to the pedals. After that, the above-mentioned process is continuously cycled, thereby achieving the purpose of fitness. But in the above process, since the chain transmission mechanism is driven by the sprocket to move the chain engaged with it, the chain pins on the chain and the teeth of the sprock...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of existing spinning bicycles proposed in the background technology, the present invention provides an electric bicycle for physical training and fitness, which can reduce the wear between the chain pin and the gear teeth, and avoid affecting the transmission of the chain transmission mechanism. The advantages of efficiency, solve the technical problems raised in the above background technology
