TECHNICAL FIELD

[0001] The present application relates to the technical field of display device, and particularly relates to a display screen group capable of being freely spliced. BACKGROUND

[0002] In the existing display device application scenarios, such as large-scale conference display, commercial advertisement delivery, stage performance, etc., it is often necessary to flexibly adjust the splicing scale and form of the display screen according to the space of the site, display requirements, etc.

[0003] However, the traditional display screen group has the problems of insufficient splicing flexibility, and it is difficult to conveniently realize the increase or decrease of the number, the adjustment of the angle, the overall form adaptation, etc., which limits the efficient application of the display screen group in diversified scenarios, and there is an urgent need for a display screen group structure with the functions of free splicing and multi-dimensional adjustment. SUMMARY

[0004] In order to overcome the problem of poor splicing flexibility of the existing display screen group, the technical problem of the present application is to provide a display screen group capable of being freely spliced.

[0005] The display screen group capable of being freely spliced comprises a telescopic base, a turnover shaft, a first electric cylinder, an upper telescopic shaft, a lower telescopic shaft, a second electric cylinder, a scissor folding support, a display screen and a connecting piece. The telescopic base serves as a basic support component and provides a stable support basis for the entire display screen group. The top end of the telescopic base is connected with the turnover shaft through a rotary pair. The first electric cylinder is assembled between the telescopic base and the turnover shaft in a rotary connection mode. The first electric cylinder drives the turnover shaft to rotate around the hinge joint with the telescopic base. The middle section of the turnover shaft is rotatably connected with the telescopic base, forming a rotary support point. The upper and lower ends of the turnover shaft are respectively fixedly connected with two left and right upper telescopic shafts and two left and right lower telescopic shafts. The turnover shaft is fixedly connected with two left and right scissor folding supports near the first electric cylinder. The second electric cylinder is connected with the turnover shaft near the two left and right scissor folding supports through a rotary pair. The telescopic shaft of the second electric cylinder is rotatably connected with the first connecting point of the scissor folding support. A plurality of connecting pieces are fixedly connected to the upper telescopic shaft and the lower telescopic shaft. The connecting pieces are hinged structure adaptive components for realizing the hinged assembly of the display screen and the upper and lower telescopic shafts. A plurality of display screens are hingedly connected to the upper telescopic shaft and the lower telescopic shaft through the connecting pieces. The display screens on the same telescopic shaft are connected in a hinged manner, forming a series structure capable of relative rotation. The display screens on different telescopic shafts but adjacent to each other are rotatably connected to the connecting point of the same scissor folding support.

[0006] Optionally, the number of cross linkages of the scissor folding support is increased or decreased to adapt to the splicing requirements of different numbers of display screens, and the number of display screens is freely increased or decreased.

[0007] Optionally, the first electric cylinder is used as an angle adjusting driving component, and the push-pull force generated by the extension and retraction of the first electric cylinder drives the rotation of the turnover shaft around the hinge point of the extension base, thereby realizing the rotation adjustment of the display screen display surface angle.

[0008] Optionally, the display screens are connected in a hinged manner, and the connection forms a wave-shaped layout.

[0009] Optionally, the second electric cylinder changes the position of the connection point with the scissor folding support through the extension and retraction action, drives the extension or folding of the cross link of the scissor folding support, and realizes the folding and unfolding action of the display screen.

[0010] Optionally, the mounting support structure of the upper and lower two groups of display screens is constructed by the upper and lower extension shafts, and the scissor folding support shared in the middle is used to make the upper and lower two groups of display screens realize the unified extension or contraction movement with the extension and retraction action of the scissor folding support.

[0011] Compared with the prior art, the present application has the following advantages: 1. The scissor folding support of the present application adopts a cross link hinge structure, which can provide a structural basis for the free increase and decrease of the number of display screens on the one hand, and can conveniently adjust the number of display screens that can be spliced by increasing or decreasing the number of cross links, and can flexibly expand the display scale; on the other hand, under the driving of the second electric cylinder, the unfolding and folding action of the display screen can be accurately controlled, and the hinge connection between the display screens can be used to realize the diversification of the display form, such as wave shape, planar expansion shape, etc., thereby improving the richness and creativity of the display form.

[0012] 2. The first electric cylinder of the present application is used as a power source for angle adjustment, and the mechanical force generated by the extension and retraction of the first electric cylinder can stably and accurately drive the rotation of the turnover shaft, thereby adjusting the angle of the display screen display surface, which can adapt to the viewing angle requirements of different sites, such as adjusting the direction of the display screen towards different participants in a large meeting to improve the viewing experience, and dynamically adjusting the angle to enhance the visual effect in a stage performance scene.

[0018] The present invention will be further described below with reference to the accompanying drawings and examples.

[0019] Embodiment: A freely connectable display screen group, such as Figures 1-4 As shown, it includes a telescopic base 1, a flip shaft 2, a first electric cylinder 3, an upper telescopic shaft 4, a lower telescopic shaft 5, a second electric cylinder 6, a scissor-type folding bracket 7, a display screen 8 and a connecting piece 9. The telescopic base 1 serves as a basic supporting component to provide a stable supporting foundation for the entire display screen 8 group. The top of the telescopic base 1 is connected to the flip shaft 2 through a rotating pair. The first electric cylinder 3 is assembled between the telescopic base 1 and the flip shaft 2 in a rotating connection manner. The first electric cylinder 3 drives the flip shaft 2 to rotate around the hinge point with the telescopic base 1. The middle section of the flip shaft 2 is rotatably connected to the telescopic base 1 to form a rotating fulcrum. The upper and lower ends of the flip shaft 2 are respectively fixedly connected with the left and right upper telescopic shafts 4 and the left and right lower telescopic shafts 5. The flip shaft 2 is fixedly connected near the first electric cylinder 3. There are two left and right scissor-type folding brackets 7, and the flip axis 2 is connected to the second electric cylinder 6 through a rotating pair near the left and right scissor-type folding brackets 7. The telescopic axis of the second electric cylinder 6 is rotatably connected to the first connection point of the scissor-type folding bracket 7. A plurality of connecting members 9 are fixedly connected to the upper telescopic axis 4 and the lower telescopic axis 5. The connecting member 9 is an adapter component of the hinged structure, which is used to realize the hinged assembly of the display screen 8 and the upper and lower telescopic axes 5. A plurality of display screens 8 are hinged on the upper telescopic axis 4 and the lower telescopic axis 5 through the connecting member 9. The display screens 8 on the same telescopic axis are connected by a hinged manner to form a relatively rotatable series structure. The display screens 8 with different telescopic axes but adjacent to each other are rotatably connected to the connection point of the same scissor-type folding bracket 7.

[0020] like Figure 4 As shown, the scissor-type folding bracket 7 can flexibly adapt to the splicing requirements of different numbers of display screens 8 by changing the number of cross-links. When the display requirements change, there is no need to replace the entire bracket. Only the number of cross-links needs to be adjusted to conveniently increase or decrease the number of display screens 8, allowing the display screen group to be freely expanded or streamlined according to the actual scene, thereby improving splicing flexibility and scene adaptability.

[0021] like Figures 1-2 As shown, the first electric cylinder 3 serves as an angle adjustment drive component. By virtue of the push-pull force generated by its own extension and contraction, it drives the flip axis 2 to rotate around the hinge point with the telescopic base 1. During this process, the flip axis 2 is linked with other components to accurately realize the rotation adjustment of the display surface angle of the display screen 8, which can adapt to different viewing angles, such as facing people in different areas in a meeting scene, and coordinating with the audience's movement lines in an exhibition scene, thereby improving the viewing experience.

[0022] As shown in Figures 1-2 , the display screens 8 are connected by hinged connection and arranged in a wavy shape. This connection allows the display screens 8 to adjust their relative positions and attitudes flexibly when the scissors-type folding support 7 and other components are in action, which can better adapt to the stretching and folding actions of the support, realize diversified morphological changes (such as wavy display), avoid damage to the display screens due to forced deformation, and ensure structural stability and display creativity.

[0023] As shown in Figures 1-4 , the second electric cylinder 6 changes the position of the connection point with the scissors-type folding support 7 through stretching and contraction, drives the cross-link of the scissors-type folding support 7 to expand or contract, and directly relates the folding and unfolding of the display screens 8. This allows the display screen group to quickly adjust its shape according to the use requirements (such as folding when storing and unfolding when displaying), is convenient to operate and can accurately control the display state, and improves the use convenience and controllability of the display shape.

[0024] As shown in Figures 1-4 , the upper and lower stretching shafts 4 and 5 construct the mounting and supporting structures of the upper and lower display screen groups 8, cooperate with the scissors-type folding support 7 shared in the middle, and allow the upper and lower display screens 8 to move synchronously with the stretching and contraction of the scissors-type folding support 7. This design makes the movement of the upper and lower display screen groups coordinated and unified, simplifies the structure, ensures the consistent movement of the upper and lower display screens when adjusting the display shape (such as unfolding and contraction), improves the regularity and coordination of the overall display, and is convenient for unified control and management.

[0025] During the display operation, the process is as follows: first, extend the stretching base 1 and adjust it to the initial supporting height suitable for the subsequent structural movement to provide a basic space; then, start the first electric cylinder 3, the stretching shaft of the first electric cylinder 3 is elongated, and the pushing and pulling force is applied to the turnover shaft 2 to rotate the turnover shaft 2 around the middle segment and the rotating connection point with the stretching base 1, so that the display surface of the display screen 8 faces the target user's visual angle; then, according to the actual display requirements, selectively start the second electric cylinder 6 on the left side, right side or both sides of the turnover shaft 2, the stretching shaft of the second electric cylinder 6 is elongated, a pushing force is applied to the scissors-type folding support 7, and the cross-link structure of the scissors-type folding support 7 is driven to open. Since the display screens 8 are connected by hinged connection, during the opening process of the scissors-type folding support 7, the display screens 8 connected thereto will be unfolded, and at the same time, the upper and lower stretching shafts 4 and 5 will be synchronously opened. The upper and lower stretching shafts 5 provide supporting points for the unfolded display screens 8 through the connecting pieces 9, and ensure the structural stability of the unfolded display screens 8.

[0026] When the number of display screens 8 needs to be increased for display, based on the expandable characteristics of the scissor folding support 7, the number of cross-link sets of the scissor folding support 7 is increased, the effective length is extended, and at the corresponding display screen 8 hinge point positions of the upper and lower telescopic shafts 4 and 5, the newly added display screen 8 is assembled through the connecting piece 9, the splicing and expansion of the display screen 8 are completed, and the display demand of a larger scale is adapted.

[0027] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present application. Those skilled in the art will understand that variations of the present application will be included within the scope of the claims herein.
