Title:
HUB CHARGING DEVICE, DISPLAY DEVICE, AND DISPLAY CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/036886
Kind Code:
A1
Abstract:
A hub charging device, a display device and a display control circuit. The hub charging device comprises: a generator assembly (100), a control board (600) and a plurality of storage batteries (900), the control board (600) controlling the generator assembly (100) to sequentially charge the storage batteries (900). The hub charging device further comprises a sensing assembly (510) and a display assembly (400). The control board (600) controls the hub charging device to supply power to the display assembly (400). The control panel (600) controls the color and turning on/off of the display assembly (400), and controls, according to a sensing signal generated by the sensing assembly (510), the display assembly (400) to present a light-emitting pattern corresponding to a pre-display pattern. The device uses the rotation of a hub to drive the generator assembly (100) to generate an induced current, so as to charge the storage batteries (900), and controls, according to the rotation of the hub, the display assembly (400) to display. Each component is simple and easy to manufacture, realizing a low-cost and environment-friendly and efficient power generation display mechanism.
