Description

Technical Field

[0001] The present invention relates to the field of rotating display, and in particular to a foldable rotating display device. Background Art

[0002] The flat rotating holographic display screen uses a rotating LED light bar to achieve a holographic display effect. Due to the inherent limitations of the structure, the display size of a single rotating device is limited. In situations where a larger display screen is required, multiple devices will be used for splicing display. Since the light bar movement area of ​​a single holographic device is circular, when the screen is spliced, the light bars of two adjacent devices will collide and may cause deformation and damage to the light bars. The usual solution is to adjust the front and back positions of the two adjacent devices so that they are in a front and back position in space, thereby avoiding possible collisions between the light bars. However, due to the adjustment of the front and back positions, the display screen is not actually on the same plane, so once the viewer's position changes, the display screen will inevitably be misaligned, greatly affecting the display effect of the screen.

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is sought, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0015] In the description of the present application, it should be understood that the terms "center", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0016] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the feature. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0017] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0018] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0019] like Figure 1 and Figure 2 As shown, in this embodiment, the holographic display device is composed of a base 1, a device body 2, a power-off type electromagnet 3, a ferromagnetic metal sheet 4, a light bar 5, a flexible electrical connection 6, and a hinge 7.

[0020] The top of the device body 2 is connected to the light bar 5 by a hinge 7. The light bar 5 can rotate backward around the connection and switch between a folded state and an unfolded state. Except when the device is working normally and has completed the speed synchronization with the same group of linked screen devices, the light bar 5 is in a folded state. The control panel controls the light bar 5 to ensure that the light bar 5 will not be incorrectly unfolded. When the device is working normally and has completed the speed synchronization with the same group of linked screen devices, the control panel releases the light bar 5. Under the action of centrifugal force, the light bar automatically unfolds and returns to normal, realizing normal display of the picture. When multiple rotating display devices are displayed in combination on the same plane, if the devices do not operate synchronously normally, the devices are in a folded state, such as Figure 2As shown, at this time, the de-energized electromagnet 3 is not energized, and is attracted together with the ferromagnetic metal sheet 4, pulling the light bar to fold backwards, ensuring that the light bar 5 of the device will not collide with the light bar 5 of the adjacent device.

[0021] When the device is in normal synchronization, the device is in the expanded state, such as Figure 1 As shown, at this time, the de-energized electromagnet is energized to release the ferromagnetic metal sheet 4. The light bar slowly returns to the normal state under the action of centrifugal force and hinge 7 damping, and switches to the unfolded state.

[0022] 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 is used to ensure that the light bar is in a folded state when the power is off, and the energized electromagnet is energized when the light bar needs to be unfolded to drive the light bar to unfold; the de-energized electromagnet 3 and the ferromagnetic metal sheet 4 can also be replaced with a push-pull electromagnet or a common motor to drive the light bar to switch between the folded state and the unfolded state; the hinge connection between the light bar 5 and the device body can also be replaced with other rotatable connection mechanical structures. The present invention solves the problem of image misalignment during the joint display of rotating display devices by folding the light bar, which has great progressive significance.
