An electric power-assisted bicycle

Abstract

The present invention relates to a bicycle, more specifically an electric power-assisted bicycle, including a wheel hub, an arc wheel, a skeleton, a bogie, a seat, a power mechanism and a transmission shaft. To improve the stability during the movement of the device, further, by setting the arc wheel, adjust the contact position between the arc wheel and the ground, and when there is a certain protrusion on the ground, the arc wheel can pre-adjust the position, so as to avoid the protrusion. The movement of the device is more stable, further equipped with a power mechanism, the power mechanism can switch between manual and electric power to meet different use requirements, and further the connection position of the bogie and seat on the frame can be adjusted to meet different requirements. Usage requirements.

Description

technical field [0001] The invention relates to a bicycle, more specifically an electric power-assisted bicycle. Background technique [0002] Bicycles are applied to all aspects of life because of their convenience. With the development of science and technology, more convenient electric bicycles have gradually entered people's field of vision. Electric bicycles refer to the use of batteries as auxiliary energy on the basis of ordinary bicycles. A mechatronic personal vehicle equipped with operating components such as motors, controllers, batteries, handlebars and brake handles, and display instrument systems; [0003] An electric power-assisted bicycle in the prior art includes a bicycle chassis, a front support shaft, an audio amplifier, a battery, a traveling motor and a driving seat. A front pole socket is installed at one end of the bicycle chassis, and the front pole socket is A front support shaft is plugged in, a front traveling wheel is installed at the lower end ...

AI Technical Summary

Problems solved by technology

[0003] An electric power-assisted bicycle in the prior art includes a bicycle chassis, a front support shaft, an audio amplifier, a battery, a traveling motor and a driving seat. A front pole socket is installed at one end of the bicycle chassis, and the front pole socket is A front support shaft is plugged in, a front traveling wheel is installed at the lower end of the front support shaft, a front operation control rod is installed at the upper end of the front support shaft, and a front handle insertion rod is inserted at the upper end of the front operation control rod. A speed control handle is installed on the upper end of the handle insertion rod, an audio amplifier is installed on one side of the front operation control lever, a USB interface is installed on one side of the audio amplifier, and a rear wheel bracket is installed on the lower side of one end of the bicycle chassis. The lower side of the rear wheel bracket is equipped with a rear traveling wheel through the rear rotating shaft, and the upper side of one end of the bicycle chassis is equipped with a driving seat through the seat frame; most electric power-assisted bicycles in the prior art are based on the two wheels of the bicycle. Improvement, in the case of electric propulsion, the speed is generally faster and the stability during the movement cannot be guaranteed
