Description

Technical Field

[0001] This utility model relates to a central control device for a folding electric bicycle, belonging to the field of electric bicycles. Background Technology

[0002] Cycling is a popular sport in daily life, and it is inseparable from bicycles. Traditional bicycles are usually large in size due to the limitations of their frames, which makes them inconvenient to carry. Therefore, folding bicycles that are easy to carry have emerged. On the other hand, because traditional bicycles are relatively strenuous when going uphill or on long distances, electric-assisted bicycles have been developed.

[0003] Electric bicycles are mechatronic personal transportation vehicles that use batteries as auxiliary power and are based on ordinary bicycles, equipped with motors, controllers, batteries, throttles, brakes, and display systems. Ordinary bicycles, once the primary mode of transportation due to their small size, light weight, low price, and convenience, are increasingly favored as pollution-free, noise-free, lightweight, and energy-efficient vehicles. With the development of urban roads, the faster pace of life, and the improvement of living standards, electric bicycles, with their labor-saving, safe, fast, and economical features, are popular among women and the elderly, becoming a new consumer trend. Compared to cars, electric bicycles have advantages such as lower energy consumption, no pollution, and convenient operation. Currently, most electric bicycles use a ring-shaped bracket fixed to the bottom of the instrument panel, which is then attached to the handlebars and secured with threads.

[0004] Chinese patent CN217533096U discloses an instrument panel bracket for an electric-assisted bicycle, including an instrument panel, a headlight, a first bracket, and a second bracket. The instrument panel is mounted above the center of the handlebars via the first bracket, and the mounting angle between the instrument panel and the first bracket is adjustable. The second bracket is detachably connected to the first bracket, and its mounting angle relative to the first bracket can be adjusted. The headlight is fixedly mounted on the second bracket and positioned in front of the center of the handlebars. This invention integrates the instrument panel and headlight onto the same bracket in the middle of the handlebars. The instrument panel is attached to the handlebars via a ring bracket and then secured with threads. This connection has poor stability; when the vehicle vibrates, the bracket and instrument panel shake significantly, causing the bolts to loosen. Frequent bolt adjustments are required, making the operation cumbersome and inconvenient. Furthermore, the instrument panel is exposed outside the handlebars, and all wiring is external, resulting in unstable electrical connections. Utility Model Content
