Technical Field

[0001] This utility model relates to the field of electric piano pedal technology, specifically a retractable electric piano pedal. Background Technology

[0002] The pedals are an important part of a digital piano. When using the pedals for sustain, it is important to control the duration of the sustain. Press the pedal on the note where sustain is needed, and then release the pedal on the note where sustain is not needed. This can effectively control the sustain effect and make the music smoother and more coherent.

[0003] In the current technology, most of the pedals of digital pianos are external pedals. External pedals may have problems with unreliable connection, are easy to loosen, and in severe cases, the pedals may even fall off. If external pedals are used improperly, such as pressing the sustain pedal for a long time, the music played may become muddy and unclear, affecting the expressiveness of the music.

[0015] Furthermore, a foot pedal controller is fixedly connected to one end of the foot pedal, and the foot pedal controller is fixedly connected to a fifth rotating shaft, which is movably connected to a second belt.

[0016] By adopting the above technical solution, the fifth rotating shaft is driven to rotate by the second belt, and the rotation of the fifth rotating shaft drives the foot pedal controller to rotate, which in turn drives the foot pedal to rotate.

Through the interaction between the first gears 4, second gears 5, first belt 7 and third gears 9, the first gears 4 and second gears 5 mesh and rotate, thereby achieving the effect that the second gears 5 drive the third gears 9 to rotate through the first belt 7.

[0030] Two sets of third gears 9 are movably connected to racks 10, two sets of racks 10 are movably connected to fourth gears 11, and two sets of fourth gears 11 are movably connected to foot pedals 16. Through the interaction between the third gears 9, racks 10, fourth gears 11, second belts 13, and foot pedal controllers 15, the third gears 9 drive the fourth gears 11 to rotate via racks 10, thereby achieving the effect that the fourth gears 11 drive the foot pedal controllers 15 to rotate via second belts 13.

[0031] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The electric piano body 1 and the piano cover 2 are movably connected by a first rotating shaft 3, and a first gear 4 is fixedly connected to the piano cover 2. By setting the above structure, the electric piano body 1 and the piano cover 2 are movably connected together by the first rotating shaft 3, so that the piano cover 2 rotates around the first rotating shaft 3. When the piano cover 2 rotates, it drives the first gear 4 to rotate.

[0032] Please see Figure 3 and Figure 4 Two sets of second gears 5 are fixedly connected to a second rotating shaft 6, and two sets of first belts 7 are movably connected to the second rotating shaft 6. By setting the above structure, the first gear 4 meshes with the second gear 5 to drive the second gear 5 to rotate, which in turn drives the second rotating shaft 6 to rotate. When the second rotating shaft 6 rotates, it drives the third rotating shaft 8 to rotate through the first belts 7.

[0033] Please see Figure 3 and Figure 4 Two sets of third gears 9 are fixedly connected to a third rotating shaft 8, and the third rotating shaft 8 is movably connected to a first belt 7. By setting the above structure, the first belt 7 drives the third rotating shaft 8 to rotate, and the rotation of the third rotating shaft 8 drives the third gear 9 to rotate.

[0034] Please see Figure 3 and Figure 5 Two sets of fourth gears 11 are fixedly connected to a fourth rotating shaft 12, and two sets of second belts 13 are movably connected to the fourth rotating shaft 12. By setting the above structure, the fourth rotating shaft 12 is driven to rotate by the rotation of the fourth gear 11, and the rotation of the fourth rotating shaft 12 drives the fifth rotating shaft 14 to rotate through the second belts 13.

[0035] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 One end of the foot pedal 16 is fixedly connected to a foot pedal controller 15, and the foot pedal controller 15 is fixedly connected to a fifth rotating shaft 14. The fifth rotating shaft 14 is movably connected to a second belt 13. By setting the above structure, the second belt 13 drives the fifth rotating shaft 14 to rotate, and the rotation of the fifth rotating shaft 14 drives the foot pedal controller 15 to rotate, which in turn drives the foot pedal 16 to rotate.

[0036] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 A connecting wire 17 is fixedly connected to one side of the foot pedal controller 15, and the other end of the connecting wire 17 is fixedly connected to the electric piano. By setting the above structure, the foot pedal controller 15 and the electric piano are connected through the connecting wire 17. When the foot pedal 16 is pressed, the electric piano sustains the sound.

[0037] The working principle of this utility model is as follows: When in use, the piano cover 2 is opened. At this time, the first gear 4, which is fixedly connected to the piano cover 2, rotates around the first rotating shaft 3. When the first rotating shaft 4 rotates, it meshes with the second gear 5, causing the second gear 5 to rotate. The rotation of the second gear 5 causes the second rotating shaft 6 to rotate. The second rotating shaft 6 drives the third rotating shaft 8 to rotate through the first belt 7. The rotation of the third rotating shaft 8 drives the third gear 9 to rotate. When the third gear 9 rotates, it meshes with the rack 10, causing the rack 10 to move. When the rack 10 moves, it drives the fourth gear 11 to rotate. The rotation of the fourth gear 11 drives the fourth rotating shaft 12 to rotate. The rotation of the fourth rotating shaft 12 drives the fifth rotating shaft 14 to rotate through the second belt 13. The rotation of the fifth rotating shaft 14 drives the foot pedal controller 15 to rotate, thereby causing the foot pedal 16 to rotate 90 degrees. At this time, the foot pedal 16 can be used.

[0038] When the piano lid 2 is closed after use, the foot pedal 16 rotates back to its initial position for storage, preventing the foot pedal 16 from being bumped and affecting its use.
