[0039] See Figure 1 、 Figure 2 The baffle 609 is engaged with the inner side of the slot 601, and the baffle 609 is adapted to the side groove 607. The ingenious setting of the baffle 609 significantly improves the stability of the locking mechanism, effectively prevents accidental unlocking due to external force, and ensures the safety and stability of the electronic piano in the folded state.

[0040] See Figure 1 、 Figure 2The hook piece 5 is plugged into the slot 601, and a movable slot 602 is opened at the rear inside of the slot 601. After the hook piece 5 is plugged into the slot 601, the blocking piece 609 can be pressed into the side slot 607. This setting simplifies the user's operation process. Just insert the hook piece 5 into the slot 601 to automatically lock it. No additional manual operation is required, which greatly improves the convenience of use.

[0041] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 There is a card block 603 that slides inside the movable slot 602, and a lever 604 is set on one side of the card block 603. The combination of the card block 603 and the lever 604 provides the user with an intuitive and easy-to-operate unlocking mechanism. Just gently push the lever to easily release the lock between the card block and the hook, making it easy to quickly fold the electronic piano.

[0042] See Figure 1 、 Figure 4 The lever 604 runs through one side of the first half of the piano 1, and a pick 605 is provided at one end of the lever 604. The addition of the pick 605 makes the unlocking operation more intuitive and convenient. The user does not need to laboriously find the position of the lever, and can complete the unlocking by simply touching the pick, which improves the user experience.

[0043] See Figure 1 、 Figure 2 A spring 606 is provided on the outside of the lever 604, and the spring 606 abuts against the block 603 and the movable groove 602. The addition of the spring 606 provides the block 603 with an automatic reset force, ensuring that the block can accurately return to its initial position after each unlocking, preparing for the next locking, and improving the reliability and service life of the locking mechanism.

[0044] See Figure 3 、 Figure 4 The spring 606 is used to cause the block 603 to reset, and after the hook piece 5 is plugged into the slot 601, the block 603 can be fixed with the hook piece 5, making it easy to splice the first half piano 1 and the second half piano 2. This arrangement makes the electronic piano extremely stable in the unfolded state, able to withstand various forces during the performance, and ensure the smooth progress of the performance.

[0045] See Figure 1 、 Figure 2 After the pick 605 is pushed outward, the block 603 and the hook 5 can be effectively unlocked, making it easier to fold the first half piano 1 and the second half piano 2. This quick unlocking mechanism allows users to quickly fold the electronic piano, saving time and energy and improving the convenience of carrying and storage.

[0046] Example 2:

[0047] See Figure 1 、 Figure 4 The inner side of the first half piano 1 is provided with a first magnetic groove 7 and a first magnetic block 9, and the inner side of the second half piano 2 is provided with a second magnetic groove 8 and a second magnetic block 10. The ingenious setting of the magnetic grooves and the magnetic blocks enhances the connection strength and positioning accuracy between the two halves of the piano, making the electronic piano more stable and reliable during the folding process.

[0048] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The first magnetic groove 7 is positioned relative to the second magnetic block 10, the first magnetic block 9 is positioned relative to the second magnetic groove 8, and the first magnetic groove 7 can be plugged into the second magnetic block 10, the first magnetic block 9 can be plugged into the second magnetic groove 8, and the outer surfaces of the first magnetic block 9 and the second magnetic block 10 are provided with a flexible sheet 11. The first magnetic block 9 and the second magnetic block 10 can be used to support the unfolded folding electronic piano, ensuring that the magnetic grooves and the magnetic blocks can be accurately aligned and generate magnetic attraction during the folding process, thereby maintaining the tight connection and stable positioning of the two halves of the piano. The provision of the flexible sheet 11 not only protects the magnetic blocks from external impact and wear, but also increases the friction between the magnetic blocks and the contact surface, making the magnetic connection more stable and reliable. At the same time, while playing a connecting and positioning role, the magnetic blocks can also serve as support points to support the unfolded folding electronic piano, thereby improving the stability and load-bearing capacity of the electronic piano.

[0049] The implementation principle of the present invention is as follows: First, when the electronic piano needs to be unfolded, the first half piano 1 and the second half piano 2 can be gently unfolded outward with the rotating shaft 4 as the center until they reach a fully unfolded state. When the two half pianos are fully unfolded, the hook piece 5 on the top of the second half piano 2 is inserted into the slot 601 on the top of the first half piano 1. As the hook piece goes deeper, it presses the baffle 609 on the inner wall of the slot 601 into the side groove 607. The adaptive setting of the baffle 609 and the side groove 607 ensures the smoothness and stability of the baffle during the rotation process. At the same time, the torsion spring rotating shaft 608 provides the baffle with a reset force. Once the hook piece 5 is fully inserted into the slot 601, the block 603 in the movable slot 602 will be further engaged and fixed with the hook piece 5 under the action of the spring 606, thereby enhancing the stability of the connection between the two half pianos.

[0050] After the electronic piano is unfolded and locked, you can start using it. Play using key 3 and adjust the volume, tone and other settings as needed;

[0051] After use, you can find the pick 605 on the side of the first half of the piano 1 and push it outward. This action drives the block 603 to move through the lever 604, so that it is unlocked from the hook 5 on the top of the second half of the piano 2. Under the action of the spring 606, the block 603 will automatically return to the initial position, ready for the next locking operation. After the two half pianos are separated, the blocking piece 609 will return to its original position to cover the slot 601 and protect the slot 601.

[0052] Parts not involved in the present invention are the same as those in the prior art or can be implemented by using the prior art, and will not be described in detail here.
