Abstract

The invention discloses a vehicle-mounted large LED (light-emitting diode) combined screen and an opening and closing method. The vehicle-mounted large LED combined screen comprises a carrying vehicle, a large LED combined screen and a carriage; one of two longitudinal side walls of the carriage is a longitudinal side wall capable of turning over; one longitudinal side of a top cover is hinged to the upper side of a fixed side wall; the lower side of the longitudinal side wall capable of turning over is hinged to the longitudinal side edge of a platform of the carrying vehicle; the large LED combined screen comprises an upper overturn screen and a lower fixed screen; a pair of longitudinal side wall opening and closing push rods capable of turning over, a pair of overturn push rods and a pair of top cover opening and closing push rods are respectively arranged in the carriage. The opening and closing method comprises the following steps of 1) sequentially opening the top cover, the longitudinal side wall capable of turning over and the upper overturn screen according to an opening procedure, so that the upper overturn screen and the lower fixed screen are vertically spliced to form an integral large screen; 2) performing a closing procedure in an opposite way. The large LED combined screen is compact in structure and convenient to use, the service life of the large LED combined screen is prolonged, and lots of manpower and material resources are saved.

Description

technical field [0001] The present invention relates to a mobile large-scale LED display screen, in particular to a large-scale LED composite screen installed on a van, the large-scale LED composite screen consists of at least two large-scale LED display screens It is combined and belongs to the technical field of special vehicles. Background technique [0002] With the continuous development of display technology combining sound and light, large-scale LED combined screens are more and more widely used in outdoor plazas, campuses, sports fields for cultural performances or sports activities, and some places that need to display live scenes. At present, fixed large-scale LED combination screens are relatively common, and are generally erected on fixed places or buildings, such as gymnasiums and urban landmarks. When it needs to be applied in a temporary outdoor place, it needs to be transported to the site two to three days in advance, and then a lot of manpower and material...
