Description

Technical Field

[0001] This utility model relates to the field of rotating displays, specifically to a foldable rotating display device. Background Technology

[0002] Planar rotating holographic displays use rotating LED strips to achieve the holographic effect. Due to the inherent limitations of this structure, the display size of a single rotating device is limited. In situations requiring a larger display screen, multiple devices are used for splicing. Because the movement area of ​​the LED strips in a single holographic device is circular, the LED strips of adjacent devices may collide during image splicing, potentially causing deformation and damage. The usual solution is to adjust the front-to-back positions of adjacent devices to avoid potential collisions. However, this adjustment results in the displayed image not being on the same plane. Consequently, if the viewer's position changes, the displayed image will inevitably become misaligned, significantly affecting the display effect. Summary of the Invention

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0016] In the description of this application, it should be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the equipment or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0017] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0019] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] like Figure 1 and Figure 2 As shown, in this embodiment, the holographic display device consists of a base 1, a device body 2, a power-off electromagnet 3, a ferromagnetic metal sheet 4, a light strip 5, a flexible electrical connection 6, and a hinge 7.

[0021] The top of the main body 2 is connected to the light strip 5 via a hinge 7. The light strip 5 can rotate backward around the connection point and switch between a folded state and an unfolded state. Except when the equipment is working normally and has achieved speed synchronization with other devices in the same group of screens, the light strip 5 is always in the folded state. The control board controls the light strip 5 to ensure that it does not unfold incorrectly. When the equipment is working normally and has achieved speed synchronization with other devices in the same group of screens, the control board releases the light strip 5. Under the action of centrifugal force, the light strip automatically unfolds back to its original position, realizing normal display of the image.

[0022] When multiple rotating display devices are combined and displayed on the same plane, if the devices do not operate synchronously, the devices will be in a folded state, such as... Figure 2As shown, at this time, the de-energized electromagnet 3 is not powered and is attracted together with the ferromagnetic metal sheet 4, pulling the light strip backward to ensure that the light strip 5 of the device will not collide with the light strip 5 of the adjacent device.

[0023] When the equipment is running normally in synchronized mode, it is in the deployed state, such as... Figure 1 As shown, at this time, the de-energized electromagnet is energized, releasing the ferromagnetic metal sheet 4. Under the action of centrifugal force and damping of hinge 7, the light strip slowly returns to the upright position and switches to the unfolded state.

[0024] In other embodiments, the de-energized electromagnet 3 and the ferromagnetic metal sheet 4 can be replaced with a combination of an energized electromagnet and a spring. That is, the spring ensures the light strip is folded in the de-energized state, and the energized electromagnet is energized when the light strip needs to be unfolded, driving the light strip to unfold. The de-energized electromagnet 3 and the ferromagnetic metal sheet 4 can also be replaced with a push-pull electromagnet or a regular motor to drive the light strip between the folded and unfolded states. The hinge connection between the light strip 5 and the device body can also be replaced with other rotatable connecting mechanical structures. This invention solves the problem of image misalignment during the joint display of rotating display devices by using a folded light strip, which is of great progressive significance.
