[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an electric piano music stand with automatic page turning, which has the following beneficial effects:

[0018] 1. This automatic page-turning electric piano music stand, through the setting of a fixed base frame, adjustment mechanism, and fixing mechanism, allows for manual adjustment of the extension plate height via a handle to meet usage needs in different situations. Before adjustment, the connecting plate is pulled by the handle, causing the connecting plate to slide two right-angle blocks on the fixed plate, simultaneously moving the locking block. Align the locking block with the corresponding locking hole on the extension plate. After the height adjustment is complete, the handle is released. Under the elastic force of the fixing spring, the U-shaped plate moves the right-angle blocks and connecting plate back to their original positions, causing the locking block to engage in the locking hole, thereby fixing the extension plate to the fixed base frame, ensuring the stability of the support plate height, and achieving the purpose of height adjustment.

[0019] 2. This automatic page-turning electric piano music stand, through the setting of a flipping mechanism and a pushing mechanism, starts a dual-axis motor. Its top output shaft drives the swing plate to swing, and the bottom output shaft drives the rotating wheel to rotate. When the rotating wheel rotates, it generates friction with the piano sheet music paper on the front side of the support plate, causing the paper to curl, making the sheet music easier to flip up by the flipping rod, improving the smoothness and reliability of page turning. Subsequently, the servo motor is started, and its output shaft drives the rotating shaft to rotate. The rotating shaft drives the flipping rod to rotate through the mounting ring. When the flipping rod rotates to contact the curled sheet music, it can flip up the sheet music, realizing the purpose of automatic page turning. Attached Figure Description

[0032] The fixing mechanism 3 includes a fixing plate 31. Fixing plates 31 are fixedly installed on both the left and right sides of the fixing base frame 1, providing installation positions for components such as right-angle blocks 32 and U-shaped plates 36. These plates form the basic support structure of the fixing mechanism.

[0034] The limiting component 7 includes a T-shaped plate 71. The bottom of the support plate 5 is fixedly installed with the T-shaped plate 71, which provides a sliding track for the sliding plate 72, allowing the sliding plate 72 to slide on its outer side, thereby adjusting the distance between the two limiting plates 77. Two sliding plates 72 are slidably installed on the outer side of the T-shaped plate 71, which can move left and right on the T-shaped plate 71 and adapt to different widths of sheet music by changing their own position. The front side of the sliding plate 72 has an installation groove 73, and the inner side of the installation groove 73 has a movable plate 74 slidably installed. The rear side of the movable plate 74 is fixedly installed with a telescopic spring 75 that is fixedly connected to the rear side of the inner wall of the installation groove 73, providing elasticity to the movable plate 74, so that the limiting plate 77 can automatically adjust its position according to the thickness of the sheet music and effectively limit the sheet music. A connecting rod 76 extending to the outer side of the sliding plate 72 is fixedly installed on one side of the movable plate 74, and a limiting plate 77 that fits against the front side of the support plate 4 is fixedly installed on the rear side of the connecting rod 76.

[0035] The right side of the sliding plate 72 is provided with a mounting strip hole that matches the movement trajectory of the connecting rod 76. The mounting strip hole is connected to the right side of the inner wall of the mounting groove 73. The rear side of the limiting plate 77 is provided with an anti-slip pad, which increases the friction between the plate and the sheet music and prevents the sheet music from slipping.

[0036] The flipping mechanism 8 includes a motor frame 81. The motor frame 81 extending to the rear side is fixedly installed on the top of the support plate 4. A servo motor 82 is fixedly installed on the inner side of the motor frame 81 as the power source of the flipping mechanism. Its output shaft drives the rotating shaft 83 to rotate, providing power for the rotation of the flipping rod 85. A rotating shaft 83 extending to the front side of the support plate 4 is fixedly installed at the output shaft of the servo motor 82. A mounting ring 84 is fixedly installed on the outer side of the rotating shaft 83. A flipping rod 85 is fixedly installed on the right side of the mounting ring 84. During rotation, it contacts the sheet music and flips the sheet music, realizing the automatic page-turning function.

[0037] The pushing mechanism 9 includes a mounting base 91. The mounting base 91, located to the right of the flipping rod 85, is fixedly mounted on the front side of the support plate 4, providing a mounting position for the rotating block 92 and serving to connect the support plate and the rotating block 92. The rotating block 92, extending to its left side, is rotatably connected to the inner side of the mounting base 91 and can rotate within the mounting base 91, providing a mounting base for the mounting frame 93 and allowing the mounting frame 93 to have a certain swing space. The mounting frame 93 is fixedly mounted on the left side of the rotating block 92. A dual-axis motor 94 is fixedly mounted on the rear side of the inner wall of the mounting frame 93. The top output shaft of the dual-axis motor 94 extends to the top of the mounting frame 93 and a swing plate 95 is fixedly mounted thereon. The bottom output shaft of the dual-axis motor 94 extends to the bottom of the mounting frame 93 and a rotating wheel 96 that fits against the front side of the support plate 4 is fixedly mounted thereon.

[0038] During the page-turning process, the dual-axis motor 94 drives the swing plate 95 and the rotating wheel 96 to rotate counterclockwise synchronously. After one side of the page is turned, the swing plate 95 continues to rotate. At this time, it will contact the front side of the support plate 4 and lift the mounting frame 93, causing it to deflect under the support of the mounting base 91 and the rotating block 92. This causes the rotating wheel 96 to leave the sheet music. During the period when the swing plate 95 is in contact with the support plate 4, the rotating wheel 96 no longer turns the paper. After the swing plate 95 is separated from the support plate 4, the mounting frame 93 drives the rotating wheel 96 to reset under the action of gravity and contact the paper again to turn the page.

[0039] A rubber ring is provided on the outer side of the rotating wheel 96 to increase the friction between it and the support plate 4. During rotation, the friction helps to push the sheet music and improves the smoothness and reliability of page turning. A circular hole adapted to the rotating shaft 83 is provided on the inner side of the support plate 4.

[0040] In use, place the fixed base frame 1 in a suitable position, such as next to a piano. Pull the connecting plate 33 by the handle 34. The connecting plate 33 causes the two right-angle blocks 32 to slide on the fixed plate 31, and at the same time, it causes the locking block 35 to move. Align the locking block 35 with the corresponding locking hole on the extension plate 201. After the height adjustment is completed, release the handle 34. Under the elastic force of the fixed spring 38, the U-shaped plate 36 causes the right-angle blocks 32 and the connecting plate 33 to reset, so that the locking block 35 is locked into the locking hole, thereby fixing the extension plate 201 on the fixed base frame 1. Then, adjust the tilt angle of the support plate 4 according to the user's height and playing habits. Start the servo motor 206. Its output shaft drives the threaded rod 207 to rotate, causing the threaded block 208 to move up and down along the threaded rod 207. The U-shaped frame 209 moves up and down accordingly, causing the extension plate 201 to move on the fixed base frame 1. The inner side slides up and down, thereby driving the support plate 4 to swing up and down through the fixed seat 202 and support rod 203, realizing the adjustment of the piano music stand tilt angle. After the adjustment is completed, the servo motor 206 is turned off, and the sheet music is placed on the tray 5 so that the bottom of the sheet music is located behind the stop bar 6. According to the width of the sheet music, the sliding plate 72 is pushed to slide on the T-shaped plate 71, and the distance between the two limit plates 77 is adjusted so that the limit plates 77 are close to the front side of the last two pages of the sheet music to limit the sheet music. During the playing process, the servo motor 82 and the dual-axis motor 94 are started. The servo motor 82 drives the flipping rod 85 to rotate, realizing the automatic page turning of the sheet music. The dual-axis motor 94 drives the swing plate 95 to swing and the rotating wheel 96 to rotate, assisting the sheet music to turn the pages and ensuring the page turning process is smooth. During the performance, the start and stop of the motor can be controlled as needed to realize continuous or intermittent automatic page turning.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] In summary, this automatic page-turning electric piano music stand, by setting up a fixed base frame 1, an adjustment mechanism 2, and a fixing mechanism 3, allows for manual adjustment of the height of the extension plate 201 via a handle 210, meeting usage needs in different situations. Before adjustment, the connecting plate 33 is pulled by the handle 34. The connecting plate 33 causes two right-angle blocks 32 to slide on the fixed plate 31, simultaneously moving the locking block 35. The locking block 35 is aligned with the corresponding locking hole on the extension plate 201. After the height adjustment is completed, the handle 34 is released. Under the elastic force of the fixing spring 38, the U-shaped plate 36 drives the right-angle blocks 32 and the connecting plate 33 to reset, causing the locking block 35 to engage in the locking hole, thereby fixing the extension plate 201 to the fixed base frame 1, ensuring the stability of the support plate 4's height, and achieving the purpose of height adjustment. By setting up a flipping mechanism 8 and a pushing mechanism, the height of the extension plate 201 can be further adjusted. 9. Start the dual-axis motor 94. Its top output shaft drives the swing plate 95 to swing, and its bottom output shaft drives the rotating wheel 96 to rotate. When the rotating wheel 96 rotates, it generates friction with the sheet music paper on the front side of the support plate 4, causing the paper to curl. This makes it easier for the sheet music to be flipped up by the flip rod 85, improving the smoothness and reliability of page turning. Then, start the servo motor 82. Its output shaft drives the rotating shaft 83 to rotate. The rotating shaft 83 drives the flip rod 85 to rotate through the mounting ring 84. When the flip rod 85 rotates to contact the curled sheet music, it can flip up the sheet music, achieving the purpose of automatic page turning. This solves the problem that without an automatic page turning structure, the performer does not have enough time to turn the sheet music, the operation is more troublesome, and it has a certain impact on the user experience. In addition, the height is fixed, making it inconvenient to adjust the height of the music stand as needed.
