Roof display device

Abstract

This invention provides a vehicle roof display device, comprising a support structure, a solar panel mechanism, an electronic paper display mechanism, an electronic control mechanism, and a heat dissipation mechanism. The solar panel mechanism is mounted on the support structure; the electronic paper display mechanism is mounted on the support structure; the electronic control mechanism is mounted on the support structure and electrically connected to the solar panel mechanism and the electronic paper display mechanism; the heat dissipation mechanism is mounted on the support structure, electrically connected to the solar panel mechanism, and corresponds to the electronic control mechanism. This allows the support structure to be mounted on the vehicle roof, utilizing the solar panel to provide power to the electronic paper display mechanism, electronic control mechanism, and heat dissipation mechanism, eliminating the need for complex wiring to draw external power. This enables the electronic paper display mechanism to display mobile advertisements on the vehicle roof, achieving ease of installation and energy saving.

Claims

1. A vehicle roof display device comprising: a support structure disposed on the top of a vehicle; a solar panel disposed at the top of the support structure; at least one electronic paper display mechanism disposed on at least one side of the support structure; an electronic control mechanism disposed on the support structure and electrically connected to the solar panel and the electronic paper display mechanism; and at least one heat dissipation mechanism disposed at at least one end of the support structure and electrically connected to the solar panel, and the heat dissipation mechanism corresponding to the electronic control mechanism; wherein the support structure includes a frame and at least two fixing seats, the fixing seats being respectively disposed on both sides of the bottom of the frame, the solar panel being disposed at the top of the frame, the electronic paper display mechanism being disposed on at least one side of the frame, the electronic control mechanism being disposed on the frame, and the heat dissipation mechanism being disposed at at least one end of the frame; The electronic control mechanism includes a photoelectric conversion module, a rechargeable battery, a playback control module, a light source sensing module, and an auxiliary light source module.
