Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The screen turning mechanism disclosed in the embodiment of the present invention has a simple and compact structure, uses few parts, occupies a small volume, and can realize the reliable unfolding and retracting of the screen, without the need for electric brakes and rotation sensors, and the electromagnetic damping generated by the motor guarantees the protection of the screen. Gentle flipping, effectively avoiding excessive screen movement and improvi...

Abstract

The invention discloses a screen turning mechanism, which is characterized by comprising a rotating shaft and a motor, wherein the rotating shaft is connected with a screen; the motor is connected with the rotating shaft for transmission; an electromagnetic damping loop capable of forming a closed circuit with the motor only when the motor is in a power-off state is connected onto the motor; the rotating shaft is also connected with an elastic mechanism; when the motor is electrified, the rotating shaft is driven to rotate to unfold the screen; the rotating shaft drives the elastic mechanism to generate elastic deformation to perform energy storage; when the motor is powered off, the elastic mechanism releases the stored energy to drive the rotating shaft to rotate for withdrawing the screen. The screen turning mechanism has the advantages that the structure is simple and compact; the occupied size is small; the working life is long; the elastic component is used for realizing the goal of automatically withdrawing the screen during the power off; in addition, in the withdrawal process, the electromagnetic damping is used for decelerating the turning speed, so that the screen can be gently withdrawn; the screen damage due to too fast action is avoided.

Description

technical field [0001] The invention relates to the technical field of a display screen retractable system, in particular to a screen turning mechanism. Background technique [0002] On airplanes or trains, there are usually screen devices used to play movies, advertisements and other information to passengers. In order to reduce the impact of the screen device on the space, the screen device is usually equipped with a retractable mechanism. The retractable mechanism unfolds the screen device, and then retracts the screen device through the retractable mechanism when the screen device is not in use, so as to prevent the screen device from occupying too much space and affect the movement of passengers, and at the same time protect the screen device itself, preventing passengers from The screen device will be damaged by accidental movement. [0003] The screen device in the prior art usually uses a flip mechanism to realize the retraction of the screen. The flip mechanism inc...
