[0043] The embodiment of the present disclosure provides a hanging matrix screen 5 device that can be raised and lowered and flipped. Under the drive of external force, the rotating shafts 2 on both sides can rotate respectively. Then, the reels 3 on both sides are driven to rotate respectively, and finally the multiple first steel wire ropes or multiple second steel wire ropes on both sides are respectively wound up or opened. When the multiple first steel wire ropes or multiple second steel wire ropes on both sides are wound up or opened at the same time, the various positions of the second bracket 4 can be synchronously raised or lowered, thereby realizing the lifting function of the screen 5. When the multiple first steel wire ropes or multiple second steel wire ropes on both sides are not wound up or opened synchronously, or one of the multiple first steel wire ropes or multiple second steel wire ropes on both sides is wound up or opened while the other remains unchanged, the second bracket 4 can be rotated forward or backward, thereby realizing the flipping function of the screen 5. In addition, the screen 5 can be flipped 90° in both the front and rear directions, and the display content of the screen 5 can be displayed at multiple angles, thereby improving the display effect.

[0044] Optionally, combined Figures 3 to 10 As shown, it also includes a motor 6, a driving sprocket, a driven sprocket and a chain 7. The motor 6 is installed on the first bracket 1, and is located on both sides of the first bracket 1 along the width direction of the first bracket 1. The motors 6 on both sides are used to provide driving force. The driving sprockets are respectively installed on the rotating ends of the motors 6 on both sides, and rotate under the drive of the motors 6 on both sides. The driven sprockets are respectively installed on the rotating shafts 2 on both sides, and are respectively used to drive the driven sprockets on both sides to perform rotation-seeking motion. The chains 7 are respectively installed between the driving sprocket and the driven sprocket on the same side, and are respectively used to transmit driving force.

[0045] In the disclosed embodiment, the motors 6 on both sides are controlled to work respectively, so as to drive the driving sprockets on both sides to rotate. The chains 7 on both sides can drive the driven sprockets on both sides to rotate respectively. Finally, the rotating shafts 2 on both sides are driven to rotate respectively, so as to realize the function of free rotation of the rotating shafts 2 on both sides.

[0046] Optionally, combined Figures 3 to 10 As shown, it also includes a first guide rail 8, a first slider 9, a support plate 10, a support seat 11 and a guide wheel 12. The first guide rail 8 is installed on the first bracket 1 along the length direction of the first bracket 1, and is located on both sides of the first bracket 1 along the width direction of the first bracket 1. The first guide rails 8 on both sides are respectively used to support and install the rotatable first slider 9. The first slider 9 is slidably installed on the first guide rails 8 on both sides, and plays a guiding and supporting role together with the first guide rails 8 on both sides. The support plates 10 are respectively installed on the first sliders on both sides, and can slide along the length direction of the first bracket 1 under the guiding and supporting action of the first guide rails 8 and the first slider 9 on both sides. The support seats 11 are evenly installed on the support plates 10 on both sides along the length direction of the first bracket 1, and the multiple support seats 11 on both sides are respectively used to support and install the rotatable guide wheels 12. The guide wheels 12 are respectively installed on the multiple support seats 11 on both sides, and are respectively used to guide the directions of the multiple first steel wire ropes and the multiple second steel wire ropes on both sides.

[0047] In the disclosed embodiment, the multiple first steel wire ropes and the multiple second steel wire ropes are respectively wound around the drums 3 on both sides after passing through the multiple guide wheels 12 on both sides. During use, as the multiple first steel wire ropes and the multiple second steel wire ropes are wound or unfolded, the support plates 10 on both sides move along the length direction of the first bracket 1. This then drives the multiple support seats 11 on both sides to move along the length direction of the first bracket 1, and finally drives the multiple guide wheels 12 on both sides to move along the length direction of the first bracket 1. Thus, the multiple first steel wire ropes and the multiple second steel wire ropes on both sides are guided in direction, so that the multiple first steel wire ropes and the multiple second steel wire ropes on both sides can be evenly wound around the drums 3 on both sides, or evenly unfolded from the drums 3 on both sides.

[0048] Optionally, combined Figure 3 , Figure 4 , Fig. 9 and Fig.10 As shown, it also includes a lead screw 13 and a nut 14. The lead screw 13 is rotatably mounted on the first bracket 1 along the length direction of the first bracket 1, and is located on both sides of the first bracket 1 along the width direction of the first bracket 1. The lead screws 13 on both sides can perform rotational motion relative to the first bracket 1. The nuts 14 are respectively mounted on the lead screws 13 on both sides, and are respectively connected to the support plates 10 on both sides, and are used to convert rotational motion into linear motion. Among them, the lead screws 13 on both sides can be controlled to rotate so that the support plates 10 on both sides move along the length direction of the first bracket 1.

[0049] In the disclosed embodiment, the ball screws 13 on both sides can rotate under the drive of external force. Under the guiding and supporting action of the first guide rails 8 and the first slider 9 on both sides, the nuts 14 on both sides can drive the support plates 10 on both sides to move along the length direction of the first bracket 1. Finally, the multiple first steel wire ropes and multiple second steel wire ropes on both sides are guided in direction, so that the multiple first steel wire ropes and multiple second steel wire ropes on both sides can be evenly wound on the reels 3 on both sides, or evenly opened from the reels 3 on both sides.

[0050] Optionally, combined Figure 3 , Figure 4 , Fig. 9 and Fig.10 As shown, it also includes a driving gear, a driven gear and a toothed belt 15. The driving gears are respectively installed on the rotating shafts 2 on both sides, and rotate under the drive of the rotating shafts 2 on both sides.

The toothed belts 15 are respectively installed between the driving gears on both sides and the driven gears on both sides, and are respectively used to transmit driving force.

[0051] In the disclosed embodiment, when the rotating shafts 2 on both sides rotate, the driving gears on both sides can be driven to rotate. Through the toothed belts 15 on both sides, the driven gears on both sides can be driven to rotate. Then the ball screws 13 on both sides are driven to rotate, and the directions of the multiple first steel wire ropes and multiple second steel wire ropes on both sides are guided. Through the design of the driving gears, the driven gears and the toothed belts 15, the screws 13 on both sides can rotate simultaneously with the rotating shafts 2 on both sides, thereby improving the coordination of the movement of the related parts and reducing the number of driving sources used.

[0052] Optionally, combined Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig. 9 and Fig.10 As shown, a scissor arm 20 is also included. The scissor arm 20 is installed between the first bracket 1 and the second bracket 4.

[0053] In the embodiment of the present disclosure, a scissor arm 20 is also included, which is installed between the first bracket 1 and the second bracket 4. The scissor arm 20 is used to improve the stability of the second bracket 4 during movement, thereby improving the stability of the screen 5 during movement. In addition, the volume is small after folding, which reduces the space occupied by the device.

[0054] Optionally, combined Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, it also includes a second guide rail 16 and a second slider 17. The second guide rail 16 is installed on the first bracket 1 along the length direction of the first bracket 1, and is used to support and install the slidable second slider 17. The second slider 17 is slidably installed on the second guide rail 16, and together they play the role of guiding support. Wherein, the scissor arm 20 includes a plurality of support rods that are cross-mounted and connected at the ends. One of the two support rods at the head end of the scissor arm 20 is rotatably installed on the second slider 17, so that one of the two support rods at the head end of the scissor arm 20 can slide and rotate relative to the first bracket 1. The other of the two support rods at the head end of the scissor arm 20 can be rotatably installed on the first bracket 1, so that the other of the two support rods at the head end of the scissor arm 20 can rotate relative to the first bracket 1. One of the two support rods at the tail end of the scissor arm 20 can be rotatably installed on the screen 5, so that one of the two support rods at the tail end of the scissor arm 20 can rotate relative to the first and second brackets 4.

[0055] In the embodiment disclosed herein, since one of the two support rods located at the head end of the scissor arm 20 can slide and rotate relative to the first bracket 1, the other of the two support rods located at the head end of the scissor arm 20 can rotate relative to the first bracket 1, and one of the two support rods located at the tail end of the scissor arm 20 can rotate relative to the first and second brackets 4, while ensuring the stability of the second bracket 4 during movement, it is still possible to perform lifting and flipping movements.
