Problems solved by technology

Since the display frame cannot be raised and lowered as required, it can only be displayed in the form of a small screen, and the display effect and safety are relatively poor
Therefore, various special vehicle manufacturers are working hard to develop lift-type LED screens. However, in the case of a narrow space on the top of the car, how to raise a wider LED screen in a small area requires not only a high lifting height, but also the impact of the entire vehicle. Height restriction, the overall height of retraction should be low, which has become an urgent problem to be solved by various special vehicle manufacturers

Abstract

The invention discloses an unfolding-type mobile service publicizing vehicle. A side board on one side of a compartment is a movable door; a first support is symmetrically arranged at the front and back ends of the movable door respectively and connected with a second support in the compartment by a hydraulic cylinder; the middle parts of the front and back ends of a display screen frame are hinged with a positioning seat on a top board by a support arm respectively; a front linear guide rail and a back linear guide rail which are parallel to each other are fixed on the top board and providedwith a slide block respectively; the slide blocks are fixed with the display screen frame; an electric motor is arranged between the two linear guide rails; the output shaft of the electric motor is coaxially connected with a lead screw; and nuts matched with the lead screw are fixed in the centers of the sides of the display screen frame. The using space of the mobile service publicizing vehiclecan be effectively expanded so as to accommodate more exhibition stands, exhibits and visitors; and a light-emitting diode (LED) screen lifting mechanism in the unfolding-type mobile service publicizing vehicle takes up small space, meets the lifting requirement of the LED screen of the mobile service publicizing vehicle, and is characterized in that: the mechanism moves stably, is safe and reliable, and the like.

Description

technical field [0001] The invention belongs to the technical field of special vehicles, and in particular relates to an unfolded mobile service publicity vehicle. Background technique [0002] As a mobile service publicity platform, the mobile service publicity vehicle can be used for promotion and publicity of products, or pre-planning and real-time display of certain large-scale activities. At present, mobile service publicity vehicles mainly use the internal space of the vehicle body as an area for display and publicity. Due to the limited internal space of the vehicle body, the effect of display and publicity will be restricted. In order to cooperate with the publicity, the mobile service publicity vehicle is usually equipped with an LED screen, and the LED screen is installed on the display frame, and the display frame is fixed to the roof of the carriage. Since the display stand cannot be raised and lowered as required, it can only be displayed in the form of a small...
