Description

Technical Field

[0001] This invention relates to the field of LED display technology, and in particular to a posture adjustment device for an air-opening and docking display screen. Background Technology

[0002] After years of rapid development, the LED industry has seen a flourishing of various display screen types, including indoor and outdoor screens, curved screens, irregularly shaped screens, and transparent screens, gradually entering people's field of vision and enriching and influencing their lives. With the progress of social civilization and the further improvement of people's cognitive level, there is also a corresponding pursuit of higher quality of life.

[0003] Existing indoor information display screens on the market, such as stadium information screens, are mostly fixed to walls for reliability and security reasons. This sacrifices flexibility and limits the application of the screens. Sometimes, the screens need to be transformed according to the content, such as separating or bringing them closer together. Therefore, existing technology uses suspended screen splicing and interlocking technology to suspend the screens in the air and drive them to move or unfold. However, due to their heavy weight and suspension by steel wires, their position needs to be constantly adjusted during docking to ensure the accuracy of the two screens' alignment. Summary of the Invention

[0004] In view of this, the present invention provides an attitude adjustment device for an aerial opening and closing docking display screen to solve the above-mentioned technical problems.

[0005] An attitude adjustment device for an aerial opening and closing docking display screen is disclosed. This device adjusts the position of the suspended display screen, which includes a fixed screen and two rotating screens rotatably mounted at both ends of the fixed screen. The attitude adjustment device includes two tracks and two attitude adjustment mechanisms slidably mounted on the tracks. Each attitude adjustment mechanism includes a support, two first adjustment components mounted on the support, two steering components mounted on the support, and two second adjustment components mounted on the steering components. Each first adjustment component includes two first wire reels mounted on the support and two first wires connecting the first wire reels to the display screen. One end of each first wire is connected to a first wire reel, and the other end is connected to the top of the fixed screen. The steering components drive the second adjustment components to rotate. Each second adjustment component includes a base mounted at one end of a rotating shaft, two second wire reels mounted on the base, and two second wires connecting the second wire reels to the display screen. One end of each second wire is connected to a second wire reel, and the other end is connected to the top of the rotating screen.

[0006] Furthermore, the display screen also includes a plurality of first folding push rods located at the connection between the rotating screen and the fixed screen. One end of the first folding push rod is movably disposed on the fixed screen, and its output end is movably connected to the rotating screen. The rotating screen can be opened or closed by extending or closing the first folding push rod.

[0007] Furthermore, the attitude adjustment mechanism also includes two pulley assemblies disposed at both ends of the bracket, the pulley assemblies being used to connect the bracket and the track to support the sliding of the bracket.

[0008] Furthermore, the two first wire reels are arranged side by side and each is equipped with a drive device to control its rotation individually, so as to wind up or unwind the first wire. The two first wire reels are located directly above the front and rear surfaces of the fixed screen, and the two first wires are respectively connected to the top of the front and rear surfaces of the fixed screen.

[0009] Furthermore, the steering assembly includes a circular slide rail mounted on the bracket, a rotating shaft rotatably inserted into the bracket and located at the center of the circular slide rail, a connecting rod mounted at one end of the rotating shaft, a movable component mounted on the bracket, and a second folding push rod mounted on the movable component.

[0010] Furthermore, the center of the circular slide rail is located at the rotational connection between the fixed screen and the rotating screen.

[0011] Furthermore, the connecting rod is provided at one end of the rotating shaft, and the second adjustment component is provided at the other end. One end of the second folding push rod is provided on the movable part, and its output end is connected to the connecting rod. When the output end of the second folding push rod extends or retracts, it drives the connecting rod to swing around the center of the rotating shaft, thereby driving the rotating shaft and the second adjustment component provided on the rotating shaft to rotate, so that they move along the circular slide rail.

[0012] Furthermore, the rotating shaft is vertically connected to the base.

[0013] Furthermore, the two second wire drums are located directly above the front and rear surfaces of the rotating screen, and the two second wires are respectively connected to the top of the front and rear surfaces of the rotating screen.

[0014] Compared with existing technologies, the attitude adjustment device for the aerial opening and closing docking display screen provided by this invention connects the top of the fixed screen and the rotating screen on both the front and rear sides via steel wires through a first adjustment component and a second adjustment component. Each steel wire can be individually controlled to raise and lower, allowing control of the position of a single display screen. The steering component can drive the second adjustment component to rotate circumferentially, thereby adjusting the opening direction of the display screen. This allows for six degrees of freedom of adjustment, ensuring the accuracy of the display screen docking. Attached Figure Description

[0023] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0024] like Figures 1 to 8 The diagram shows a schematic representation of the attitude adjustment device for an aerial opening and closing docking display screen provided by this invention. The attitude adjustment device includes two tracks 10, two suspended display screens 20, and two attitude adjustment mechanisms 30 slidably mounted on the tracks 10. It is conceivable that the attitude adjustment device also includes other functional modules, such as sensors, connecting components, etc., which are technologies well-known to those skilled in the art and will not be described in detail here.

[0025] The track 10 is used to slide the attitude adjustment mechanism 30, so that the two attitude adjustment mechanisms 30 can move along the track 10 under the drive of an external drive device to dock or separate.

[0026] The display screen 20 is a folding display screen, which forms a U-shape when folded. The display screen 20 includes a fixed screen 21, two rotating screens 22 rotatably mounted at both ends of the fixed screen 21, and multiple first folding push rods 23 located at the connection points between the rotating screens 22 and the fixed screen 21. When the display screen 20 is unfolded, the fixed screen 21 and the rotating screens 22 are parallel to each other. The unfolding principle and structure are existing technology and will not be described in detail here. One end of each first folding push rod 23 is movably mounted on the fixed screen 21 via a movable component such as a universal joint, and its output end is movably connected to the rotating screen 22. The extension and retraction of the first folding push rod 23 can cause the rotating screen 22 to unfold or close.

[0027] The attitude adjustment mechanism 30 includes a bracket 31, two pulley assemblies 32 disposed at both ends of the bracket 31, two first adjustment components 33 disposed on the bracket 31, two steering components 34 disposed on the bracket 31, and two second adjustment components 35 disposed on the steering components 34.

[0028] The bracket 31 is used to support the above-mentioned functional modules. Therefore, the bracket 31 is provided with a variety of functional structures, such as screws, bolts, clamps, etc., to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs, and will not be described in detail here.

[0029] The pulley assembly 32 is used to connect the bracket 31 and the track 10 to support the sliding of the bracket 31. The pulley assembly 32 should be existing technology and will not be described in detail here.

[0030] The first adjustment assembly 33 includes two first wire reels 331 mounted on the bracket 31, and two first wires 332 connecting the first wire reels 331 and the display screen 20. The two first adjustment assemblies 33 are respectively located directly above both ends of the fixed screen 21. The two first wire reels 331 are arranged side-by-side and each is equipped with a drive device, such as a motor, to individually control their rotation, thereby winding or unwinding the first wires 332 to control their length. The two first wire reels 331 are located directly above the front and rear surfaces of the fixed screen 21. One end of each first wire 332 is connected to a first wire reel 331, and the other end is connected to the top of the fixed screen 21. Therefore, the two first wires 332 are respectively connected to the top of the front and rear surfaces of the fixed screen 21, and the position of the fixed screen 21 can be controlled by driving the first wire reels 331. For example, simultaneously raising or lowering the reels adjusts the height, while raising one and lowering the other adjusts the tilt.

[0031] The steering assembly 34 is used to drive the second adjustment assembly 35 to rotate. The steering assembly 34 includes a circular slide rail 341 disposed on the bracket 31, a rotating shaft 342 rotatably inserted into the bracket 31 and located at the center of the circular slide rail 341, a connecting rod 343 disposed at one end of the rotating shaft 342, a movable part 344 disposed on the bracket 31, and a second folding push rod 23 disposed on the movable part 344.

[0032] The center of the circular slide rail 341 is located at the rotatable connection between the fixed screen 21 and the rotating screen 22. It supports the sliding of the second adjustment component 35. When the rotating screen 22 is unfolded, the second adjustment component 35, which suspends the rotating screen 22, also slides to the corresponding position directly above it. One end of the rotating shaft 342 is provided with the connecting rod 343, and the other end is provided with the second adjustment component 35. When the rotating shaft 342 rotates, it can drive the second adjustment component 35 to rotate around the circumference of the circular slide rail 341, thereby controlling the position of the second adjustment component 35. One end of the second folding push rod 23 is mounted on the movable member 344, and its output end is connected to the connecting rod 343. The movable member 344 can support the swinging of one end of the second folding push rod 23. In this embodiment, a universal joint is used. When the output end of the second folding push rod 23 extends or retracts, it can drive the connecting rod 343 to swing around the center of the pivot 342, thereby driving the pivot 342 and the second adjustment component 35 mounted on the pivot 342 to rotate, so that they move along the circular slide rail 341 to the position corresponding to the unfolded position. It should be noted that the unfolding of the display screen 20 is achieved through the first folding push rod 23. If the first folding push rod 23 is locked, it only moves the second adjustment component 35, which will only adjust the opening direction of the display screen 20 horizontally, and will not cause the display screen 20 to unfold directly.

[0033] The second adjustment assembly 35 includes a base 351 disposed at one end of the rotating shaft 342, two second wire drums 352 disposed on the base 351, two second wires 353 connecting the second wire drums 352 and the display screen 20, and two upper pulley assemblies 354 disposed on the base 351.

[0034] The rotating shaft 342 is vertically connected to the base 351 to drive the base 351 to rotate horizontally. The structure of the second wire drum 352 is the same as that of the first wire drum 331, both having a drive device such as a motor to individually control their rotation, which will not be described in detail here. The two second wire drums 352 are located directly above the front and rear surfaces of the rotating screen 22. One end of the second wire 353 is connected to the second wire drum 352, and the other end is connected to the top of the rotating screen 22. Therefore, the two second wires 353 are respectively connected to the top of the front and rear surfaces of the rotating screen 22 and can be raised and lowered by the drive of the second wire drums 352 to control the position of the rotating screen 22. The upper pulley assembly 354 is used to connect to the circular slide rail 341.

[0035] During docking, adjustments to the six degrees of freedom along the XYZ axes are required. The adjustment of the X-axis rotation is as follows: Figure 4As shown, the rotation angle of the X-axis can be adjusted by controlling the second wire 353 of the second adjustment component 35 to wind up or unwind it, so that the meshing surfaces of the two displays 20 are relatively parallel. Adjustment of the X-axis offset is as follows: Figure 5 As shown, the rotating screen 22 can be finely adjusted by extending or retracting the first and second folding push rods 23, causing it to rotate. The second adjustment component 35 also moves accordingly. At this time, the two displays 20 will form a parallelogram shape, but this should be within the structural tolerance. Adjustments to the Y-axis rotation are as follows... Figure 6 As shown, the rotation angle of the Y-axis can be adjusted by controlling the raising and lowering of the steel wires on both sides through the second steel wire drum 352 and the first steel wire drum 331. For the adjustment of the Y-axis offset, this direction is the normal meshing direction of the two displays, i.e., the sliding direction, so no adjustment is needed. The adjustment of the Z-axis rotation is as follows... Figure 7 The second folding push rod 23 drives the steering assembly 34, causing the second adjustment assembly 35 to rotate, thereby adjusting the horizontal orientation of the opening of the display screen 20. Adjustment of the Z-axis offset is as follows... Figure 8 As shown, this direction is the height direction, indicating a misalignment. This can be adjusted by controlling the raising and lowering of all the steel cables. This achieves six degrees of freedom of adjustment, allowing the display screen to be adjusted even in any incorrect position, ensuring the accuracy of the display screen alignment.

[0036] Compared with existing technologies, the attitude adjustment device for the aerial opening and closing docking display screen provided by this invention connects the top of the fixed screen 21 and the rotating screen 22 on both the front and rear sides via steel wires, through a first adjustment component 33 and a second adjustment component 35. Each steel wire can be individually controlled to raise and lower, allowing control of the position of a single display screen. The steering component 34 can drive the second adjustment component 35 to rotate circumferentially, thereby adjusting the opening direction of the display screen 20. This allows for six degrees of freedom of adjustment, ensuring the accuracy of the display screen docking.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions or improvements within the spirit of the present invention are covered within the scope of the claims of the present invention.
