Abstract

The invention discloses a display panel of an electric bicycle, and the display panel is characterized by comprising a linear Hall element, an electric quantity display board and a controller, wherein the linear Hall element and the controller are connected with the electric quantity display board; and the electric quantity display board comprises an LED (light emitting diode) display lamp which indicates the working state of the electric bicycle. The display panel disclosed by the invention has the advantages of simple structure, convenience in installation and low production cost and can display the working state and fault state of the electric bicycle.

Description

technical field [0001] The invention relates to an electric bicycle, in particular to an electric bicycle display panel and a control method thereof. Background technique [0002] An electric bicycle refers to a special bicycle that uses a battery as an auxiliary energy source, has two wheels, and can realize human riding, electric or electric assist functions. An electric bicycle is a mechatronic personal vehicle that is equipped with operating components such as a motor, a controller, a battery, a handlebar, and a display instrument system on the basis of an ordinary bicycle. The existing electric bicycle display instrument system displays the electric quantity through the pointer, which is complex in structure, high in cost, and cannot display the fault state of the electric bicycle. Contents of the invention [0003] The purpose of the present invention is to provide an electric bicycle display panel with simple structure and easy installation, which can display the w...
