Rotatable outdoor electronic display device

Abstract

The invention discloses an outdoor electronic display device capable of rotating to avoid wind. The device comprises at least two columns; a pair of annular sliding grooves fixedly arranged at the upper ends of at least two upright columns corresponding to each other. The upper end and the lower end of the shell are respectively slidably arranged on the sliding rails in a pair of annular sliding grooves through the sliding blocks. The housing further comprises a pair of display screens respectively arranged on the outer side wall of the housing and two ventilation holes spaced between the pairof display screens. A pair of first wind speed sensors are respectively arranged on the border frames of a pair of display screens; A pair of second wind speed sensors are respectively arranged on the outer frames of the two ventilation holes; A drive assembly includes an annular rack; Drive motors and gears; and single-chip microcomputer. The device can meet the requirements of information display such as advertisements with abundant pictures of merchants. The display position of a pair of display screens can be adjusted according to the real-time wind direction and wind force so as to prolong the service life of the pair of display screens; And effective use of wind power, energy conservation and environmental protection.

Problems solved by technology

In order to sell products, merchants often use various methods for advertising. At present, the application of print advertising equipment is very common. There are traditional advertising light box equipment and various electronic advertising devices. Shopping malls, stations, airports can be seen everywhere, and indoors A large number of LCD screens or touch screens are also used for advertising display and human-computer interaction, and the publicity effect is remarkable, but this is only for indoor display and advertising

If you use a liquid crystal display to display outdoors, although the display effect is remarkable, but because the liquid crystal display is exposed to the outside for a long time, it is easy to damage the display and its supporting equipment when encountering strong winds or stormy weather, resulting in greatly shortening the service life of the display and its supporting equipment. Service life, frequent updating of equipment, increase the cost of advertising
