Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 as shown, figure 1 It is a structural schematic diagram when the solar cell of the present invention is installed on the top of the countdown card. The solar cell-3 of the present invention is installed on the position above the top of the countdown card display screen 1 through the solar bracket 2, and the shape can be designed to be similar to an umbrella structure, so that While supplying power to the countdown card, it can also shade the countdown card from the sun, rain, water and dust, and prolong the life of the countdown card. According to needs, the solar battery can also be made into a herringbone structure. The solar battery-3 accepts sunlight during the day, directly supplies power to the countdown card or charges the energy storage device of the countdown card, so as to continue to supply power under insu...

Abstract

The invention discloses a countdown card adopting a solar power supply mode, which includes a countdown card body and a solar battery power supply device for providing working current for the countdown card, and is characterized in that a solar battery power supply device is arranged on the power supply part of the countdown card. The current generated by the solar cell through photoelectric conversion passes through the power supply control circuit to supply power for the countdown card. The solar cell is placed on the top of the countdown card or on the front of the countdown card or on the side of the countdown card or on the back of the countdown card or near the place that can receive light place. The solar countdown card has the advantages of long service life, no pollution, simple structure, good use effect and wide application. incidence and prolong their lifespan. The solar countdown card not only saves electricity, but also promotes the concept of environmental protection to the public.

Description

technical field [0001] The invention relates to a novel countdown board, in particular to a countdown board using a solar power supply mode. Background technique [0002] In today's society, with the continuous introduction of major events and celebrations in the fields of politics, economy, sports, and education, such as the Olympics, World Expo, festivals, college entrance examinations, etc., countdown cards are now more and more widely used. [0003] The main body of the existing countdown card generally includes two parts: the countdown card bracket and the display screen.
