Description

Technical Field

[0001] The present invention relates to the field of display screens, and in particular to a windproof folding screen and a lifting stage. Background Art

[0002] LED display is a flat panel display composed of small LED module panels. It is used to display various information such as text, images, videos, and video signals.

[0003] Existing display screens can be roughly divided into two types based on their size: small displays, used on mobile phones, computers, tablets, or TVs; and large displays, such as advertising screens installed on buildings or foldable screens composed of multiple display panels.

[0004] The folding screen's components are connected by flexible connections (wires, hinges, and hinges, etc.). When the screen is hung and unfolded, these connections lack the rigidity to withstand external forces, making them difficult to bear and withstand wind. High winds or external forces can cause the screen to shake or even break at the flexible connections, posing a significant safety risk. Summary of the Invention

[0005] In order to solve the technical problem of insufficient strength between unit blocks of the folding screen in the above-mentioned prior art, the present invention proposes a windproof folding screen and a lifting stage.

[0006] The technical solution adopted in the present invention is:

[0007] The present invention proposes a windproof folding screen, comprising: an upper hanging bar, a plurality of unit panels connected to each other below the upper hanging bar to form a whole display surface, two upper and lower adjacent unit panels being hinged, the upper hanging bar being driven to move upward or downward by a lifting device so that the unit panels are folded or unfolded from the bottom, and further comprising: a supporting structure arranged on the back side of the single-panel element display surface and driven by a lifting device to be able to expand upward or contract downward from the bottom, and a plurality of connecting members for tightening or supporting the unit panels are connected between the supporting structure and the plurality of unit panels.

[0008] In one embodiment, the support structure includes two telescopic rods spaced vertically apart and a plurality of crossbars transversely connecting the two telescopic rods. The telescopic rods are composed of multiple sections of sleeves, each of which increases in cross-sectional size from top to bottom and is nested together. Each crossbar connects two opposing sleeves, such that the crossbars are arranged parallel from top to bottom and are connected to the tops of the sleeves. Limiting devices are provided at the top and bottom of each sleeve.

[0009] The unit boards are arranged in an array, and the crossbars are connected to the tops or bottoms of multiple unit boards in a horizontal row through multiple connecting members arranged in a row, and each row of connecting members is arranged at intervals of two horizontal rows of unit boards.

[0010] In another embodiment, the support structure includes: a plurality of folding support bars arranged at intervals, a plurality of second cross bars transversely connecting the folding support bars and parallel to the upper hanging bars, the folding support bars are composed of a plurality of connecting bars hinged end to end, the second cross bars are connected at the hinges of the connecting bars, and a second cross bar is provided for every two connecting bars.

[0011] The unit boards are arranged in an array, and the second crossbar connects the tops or bottoms of multiple unit boards in a row via a plurality of the connecting members arranged in a row, with each row of connecting members being provided every other row of unit boards. The connecting rods are arranged in parallel and spaced apart, and each end of each rod is provided with a hook for connecting the unit boards to the crossbar.

[0012] The present invention also proposes a lifting stage, comprising: a stage with a lifting opening, a lifting platform arranged at the lifting opening, and a lifting device for driving the lifting platform to rise and fall. The stage is characterized in that the stage further comprises the above-mentioned folding screen, and the upper hanging bar and the top of the supporting structure are connected to the bottom surface of the lifting platform.

[0013] Furthermore, a storage platform is provided below the stage, and when the upper hanging bar moves downward, the unit panels between the storage platform and the stage are folded and stored.

[0014] Preferably, the lifting platform is square, and the four folding screens are respectively arranged on the four sides of the bottom surface of the lifting platform.

[0015] Compared to existing technologies, the support structure of the present invention allows the folding screen to expand or retract along with the display module during its deployment. Connectors lower the back of the display module to connect to the support structure. The nodes connecting the support structure and the display module via the connectors maintain their relative positions during deployment and retraction, allowing the connectors to remain supported on the back of the display module. This increases the mechanical strength of the folding screen, providing resistance to wind and external forces. The folding screen is also integrated with a lifting stage, enhancing the stage effect.

[0025] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and may encompass internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0026] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0027] The present invention proposes a windproof folding screen, comprising: an upper hanging bar, a lower hanging bar, a plurality of unit panels 1, a support structure, and a connector 3. The upper hanging bar and the lower hanging bar are arranged in parallel, and the unit panels 1 are connected between the upper hanging bar and the lower hanging bar to form a display module, forming an entire display surface. Two adjacent unit panels 3 are hinged so that the two unit panels can be unfolded 180 degrees or fit together, and the upper and lower hinges of each unit panel can be rotated in opposite directions so that all the unit panels can be folded together. The upper hanging bar is driven up and down by a lifting device, so that when the upper hanging bar rises, the folded unit panels 1 of the display module are unfolded and raised from bottom to top in sequence, and when the upper hanging bar falls, the unfolded unit panels 1 are folded from bottom to top in sequence. The support structure is arranged on the back of the display module and can be driven by the lifting device to unfold upward or retract downward from the bottom to match the unfolding or folding of the unit panels. There are multiple connectors 3 connected between the support structure and the multiple unit boards. The nodes where the support structure and the display module are connected by the connectors maintain their relative positions during the unfolding or folding process, so that the connectors can always be connected to the back of the display module, thereby increasing the mechanical strength of the folding screen and achieving the effect of resisting wind and external forces.

[0028] Specifically, the unit boards 1 are arranged in an array, with four unit boards 1 in a horizontal row forming a display unit. Multiple display units are disposed between the upper and lower hanging bars. The upper and lower unit boards 1 are hingedly connected, and other hinged connections are also possible, all within the scope of the present invention. Two adjacent display units can be hingedly connected.

[0029] like Figure 1 、 Figure 2 As shown, in one embodiment, the support structure includes two telescopic rods 41 and multiple crossbars 42. The two telescopic rods 41 are spaced vertically and spaced apart along the transverse direction of the unit board. The telescopic rods 41 are composed of multiple sleeves 411, which increase in cross-sectional size from top to bottom and nest together. Each sleeve is provided with a stopper at the top and bottom. These stoppers, which may be raised rings, prevent the sleeve 411 from completely retracting into the other sleeve 411 below when it is moved downward, nor completely separating from the other sleeve 411 below it when it is moved upward. A crossbar 42 is connected between each sleeve 411 of the two telescopic rods 41. The crossbars 42 are parallel to the upper suspension bars, so that the multiple crossbars 42 are arranged in parallel from top to bottom. Each crossbar 42 is connected to the top of a pair of sleeves 411, so that the sleeve 411 is not directly restricted by the crossbar 42 when it is retracted into the other sleeve 411.

[0030] The unit panels 1 are arranged in an array, with each section of sleeve 411 corresponding to two horizontal rows of unit panels. The crossbars 42 of the sleeves 411 can be connected to multiple unit panels in a horizontal row near their hinge points via multiple connectors 3, maintaining a constant relative position between the crossbars 42 and the hinge points of the unit panels 1. The connectors 3 can be connected to the top or bottom of the multiple unit panels, and the multiple connectors 3 are spaced parallel to each other to ensure balanced support force across a horizontal row of unit panels 1.

[0031] When the lifting device drives the upper hanging bar to move downward, the telescopic rod 41 also contracts downward, and the bottom unit plate 1 begins to fold. At the same time, the cross bar 42 moves vertically downward following the sleeve 411, causing the connecting member 3 to move downward and maintain a supporting state during the movement.

[0032] The crossbar 42 is cylindrical and can be configured in two ways: one is to connect directly and horizontally between the two telescopic rods 41; the other is to bend the ends of the crossbar 42 vertically inward, and the bent vertical section is connected vertically to the side of the telescopic rod 41 close to the unit board, so that the horizontal portion of the crossbar 42 is close to the side of the unit board 1.

[0033] The connecting member 3 can be a rigid member with hooks 31 at both ends. One end passes through the through hole on the unit plate 1, and the hook 31 at the other end is directly hooked on the cross bar 42, so that the connecting member 3 connects the cross bar 42 and the unit plate 1. At the same time, the connecting member 3 has a certain amount of movable margin to prevent it from being too tight and affecting the folding of the unit plate and the supporting structure.

[0034] The connecting member 3 may also be a steel wire, with both ends directly wound around the unit plate 1 and the crossbar for fixation.

[0035] like Figures 3 to 5 As shown, in another embodiment, the support structure includes: three folding support bars 51 and multiple second cross bars 52. The folding support bar 51 is composed of multiple connecting bars 511 hinged end to end, and the two connecting bars 511 hinged at both ends of each connecting bar 511 rotate in opposite directions, and the plane where the rotation direction is located is parallel to the plane where the unfolded unit board 1 is located, so that the connecting bars 511 of the folding support bar 51 can be folded back and forth without affecting the unfolding and folding of the unit board 1. The second cross bar 52 connects the three folding support bars 51 transversely and is specifically installed at the hinge of two adjacent connecting bars 511 of each folding support bar 51 and is located on one side of the corresponding unit board 1, so as not to affect the unfolding and folding of the folding support bar 51. Each connecting bar 511 corresponds to a unit board 1, and a second cross bar 52 is provided every two connecting bars 511, so that the cross bars are arranged in parallel from top to bottom.

[0036] The second crossbar 52 is connected to the unit panels 1 in a horizontal row at a corresponding height, near the hinge points, via multiple connectors 3, to maintain a constant relative position between the second crossbar 52 and the hinge points of the unit panels 1. The connectors 3 can be connected to the top or bottom of the unit panels 1, with the multiple connectors 3 spaced parallel to each other to ensure balanced support for the unit panels 1 in a horizontal row.

[0037] A row of rings 521 are provided at intervals along the length direction of the second cross bar on one side of the second cross bar corresponding to the unit plate. Ring hooks 31 are provided at both ends of the connector 3. The ring hook 31 at one end is connected to the ring 521, and the ring hook at the other end passes through the through hole on the unit plate 1, so that the connector 3 connects the second cross bar 52 and the unit plate 1, and is convenient for disassembly of the connector 3. The combination of the ring hook and the ring gives the connector a certain amount of movable margin to prevent it from being too tight and affecting the folding of the unit plate and the folding bracket.

[0038] like Figure 1 、 Figure 3 As shown, the present invention also proposes a lifting stage, including: a stage 6, a lifting platform 7, a lifting device and at least one folding screen. A lifting opening is provided in the middle of the stage 6, and the lifting platform 7 is arranged at the lifting opening. The lifting platform 7 is lifted and lowered by the lifting device. The lifting device is a feasible existing technology and can be a stage elevator or a stage lifting column, which will not be described in detail. The upper hanging bar and the supporting structure are connected to the bottom surface of the lifting platform 7. When the lifting platform 7 is raised, the upper hanging bar follows the lifting platform to rise, so that the unit board 1 of the display module gradually unfolds from the bottom, and at the same time, the supporting structure follows the lifting platform to unfold upward to provide support. It can not only enhance the stage effect, but also maintain the overall strength of the display module.

[0039] A storage platform is provided under the stage 6, and the unit panels are stored on the storage platform after being folded. At the same time, when the upper hanging bar moves downward, the unit panels between the storage platform and the stage are folded and stored, so that the unit panels higher than the stage remain in an expanded state.

[0040] Specifically, the display module of the folding screen is arranged at the edge of the bottom surface of the lifting platform. The lifting platform is square, and a total of 4 folding screens are arranged parallel to the four sides of the bottom surface of the lifting platform, so that after the lifting platform is raised, there are screens set on all four sides for display. The folding screen can also be set as one, two or three, or the lifting platform can be triangular, pentagonal or other polygonal, all of which are within the protection scope of the present invention.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
