[0044] In the present technical solution, the bracket frame 16 is in a rectangular frame structure, which is installed at the edge of the piano case structure 2 where the piano surface is set. At the same time, in order to install the upper part of the piano surface, a decorative baffle 7 is provided to block a part of the liftable smart screen 3. The decorative baffle 7 can also position the liftable smart screen 3.

[0045] As a supplement to the present technical solution, a transmission seat 15 is arranged in the middle of the smart large screen 12 close to the bracket frame 16, and a screw rod 14 passing through the transmission seat 15 is installed in the middle of the bracket frame 16, and the screw rod 14 and the transmission seat 15 are connected by threads.

[0046] In order to facilitate the installation of the screw rod 14 in this technical solution, a screw rod support 19 is arranged in the middle of the bracket frame 16 to facilitate the assembly of the screw rod. At the same time, sliders 13 matching the vertical slide rails 17 are arranged at both ends of the smart large screen 12. The sliders 13 wrap the vertical slide rails 17 to prevent the smart large screen 12 from slipping when sliding.

[0047] As a supplement to the present technical solution, a servo motor 18 connected to the screw rod 14 is installed on the upper part of the bracket frame 16. In the present technical solution, a driving gear 20 is installed on the main shaft of the servo motor 18. The driving gear 20 is meshed with a driven gear 21 located at the upper end of the screw rod 14 to realize digital operation. The button can control the smart large screen 12 to move up or down.

[0048] As a supplement to the present technical solution, the right end of the rear cover 8 adopts an inclined surface structure with the lower end tilted toward the left, and the left end of the front cover 9 adopts an inclined surface structure with the lower end tilted toward the right. The hinge 26 is arranged in a docking space 25 formed by the two inclined surfaces. By setting the docking space 25, it is ensured that the torque of the hinge 26 supports the front cover 9 and the rear cover 8, avoiding the concave middle part of the foldable piano cover 5, ensuring the beauty of the piano surface, and at the same time, by setting the docking space 25, the folding operation is made more flexible.

[0049] Example

[0050] When it is necessary to play the piano, first open the piano cover through the finger groove between the foldable piano cover 5 and the stop block 22, then flip up the front cover 9 so that the front cover 9 is overlapped on the rear cover 8, then bend the stop bar 10 and overlap it on the front cover 9, and finally flip over the rear cover 8 so that the cutout 24 of the rear cover 8 contacts the support block 29. At this time, the entire foldable piano cover 5 is stored in the piano case structure 2, and the lower end of the rear cover 8 faces the storage opening 6 for shielding.

[0051] After the foldable piano cover 5 is opened, the lifting smart large screen 3 is lowered, and the servo motor 18 is started. The servo motor 18 drives the active gear 20, the active gear 20 drives the driven gear 21, and the driven gear 21 drives the screw rod 14. Under the action of the external thread of the screw rod 14, the transmission seat 15 and the smart large screen 12 slide downward. When the smart large screen 12 moves to the extreme position, the foldable piano cover 5 will be covered. After completing the whole action, you can play.

[0052] When the liftable smart large screen 3 is lowered to the extreme position, it corresponds to the piano keys. When fingering practice is needed, the liftable smart large screen 3 will display virtual keys that are exactly the same as the piano keys. The virtual keys will automatically indicate according to the digital music score, allowing beginners to practice according to the instructions, which greatly facilitates the beginners' copying practice.
