[0021] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0022] An embodiment of the present invention relates to a foldable flip key cover for a piano, such as Figure 1 and Figure 2 As shown, it includes a piano key assembly 1, a piano case 17 and a storage opening 18. The piano key assembly 1 is arranged at the lower part of the piano case 17, and the storage opening 18 is arranged on the side of the piano case 17 close to the piano keys. A key pressing block 9 is arranged in the middle part of the upper end surface of the piano key assembly 1, and the key pressing block 9 is rotatably connected to one end of the rear key cover 2 close to the storage opening 18, and the other end of the rear key cover 2 is rotatably connected to the front key cover 3. The rear key cover 2 is L-shaped, and its end close to the key pressing block 9 extends upward to form a support rod 14. When the rear key cover 2 and the front key cover 3 are arranged horizontally, the support rod 14 of the rear key cover 2 blocks the storage opening 18. When the rear key cover 2 and the front key cover 3 are folded and stored in the piano case 17, the lower end surface of the rear key cover 2 blocks the storage opening 18.

[0023] In the present technical solution, a storage opening 18 is provided at the lower part of the baffle 19 of the piano case 17 close to the keys, so that the folded rear key cover 2 and the front key cover 3 can enter the piano case, thereby increasing the overall area of ​​the piano surface.

[0024] In the present technical solution, the original whole key cover is divided into a front key cover 3 and a rear key cover 2, so that the processing steps are simplified during the processing, and the front key cover 3 and the rear key cover 2 are not easy to deform, and the structure is more stable. At the same time, by setting a connecting piece, the front key cover 3, the rear key cover 2 and the groove 5 form a foldable structure. When stored, the space for placing the display screen will be vacated, and the area between the keys and the key cover is spacious, which is convenient for the player to perform a convenient teaching and playing mode according to the content displayed on the display screen, expand the playing area, and improve the player's playing feeling.

[0025] As a supplement to the present technical solution, a vertically arranged foldable slot guard 5 is provided at the end of the lower side of the front key cover 3 close to the piano keys.

[0026] By providing the foldable slot 5 , the entire piano cover can be folded and arranged to be conveniently stored in the piano case 17 .

[0027] As a supplement to the present technical solution, the rear key cover 2 and the front key cover 3 are connected to each other via a long hinge 7. By providing the long hinge 7, the front key cover 3 can be quickly folded, making the folding operation more flexible.

[0028] As a supplement to the present technical solution, the end where the rear key cover 2 and the front key cover 3 are connected is a sloped structure with the lower end tilted toward the left, and the end where the front key cover 3 and the rear key cover 2 are connected is a sloped structure with the lower end tilted toward the right, forming a docking space with a triangular cross-section between the two.

[0029] By setting the docking space, the hinge can provide support force to the rear key cover 2 and the front key cover 3 to prevent the docking part of the two from sinking, thereby ensuring a beautiful appearance.

[0030] As a supplement to the technical solution, a hinge structure with supporting elasticity is arranged between the docking spaces.

[0031] The supporting force provided by the elastic hinge structure matches the weight of the front key cover 3 and the rear key cover 2, thereby ensuring that the joint portion of the front key cover 3 and the rear key cover 2 is in a horizontal state.

[0032] like Figures 3 to 6 As shown, as a supplement to the present technical solution, the front key cover 3 is provided with a rounded transition portion 11 on the upper side of the end of the groove block 5, and the upper part of the end of the rear key cover 2 close to the key pressing block 9 is provided with a rounded structure 10 matching the rounded transition portion 11. By providing the rounded transition portion 11, the beauty of the front end of the cover body is ensured when the key cover is opened, and by providing the rounded structure 10, the front key cover 3 is conveniently stored in the rear key cover 2.

[0033] As a supplement to the present technical solution, a cutout 16 is provided on the upper part of the support rod 14 near the key pressing block 9, and a support block 15 which can fit with the cutout 16 is provided in the middle part of the piano key assembly 1. By providing the cutout 16, the support rod 14 is conveniently matched with the support block 15, thereby improving the supporting strength.

[0034] As a supplement to the present technical solution, a support baffle 4 corresponding to the groove 5 is vertically arranged on the piano key assembly 1, and a pad 12 is arranged on the upper end of the support baffle 4. By setting the pad 12, direct contact between the groove 5 and the support baffle 4 is avoided, ensuring that no wear occurs between the two.

[0035] As a supplement to the present technical solution, a notch groove 13 is provided at the upper end of the support baffle 4. The notch groove 13 facilitates the user to insert his fingers to open the piano cover.

[0036] A key pressing block 9 is provided in the present technical solution. The key pressing block 9 can effectively and conveniently install the rear key cover 2, and can support and position the rear key cover 2 while positioning the keys. At the same time, a cavity is provided on the lower end surface of the key pressing block 9. The cavity can avoid local interference between the key pressing block 9 and the piano key assembly 1, ensuring that the normal movement of the keys is not affected when the piano cover is folded.

[0037] When the key cover of the technical solution is opened, first Figure 3 As shown, the front key cover 3 is flipped upward around the long hinge 7 until the front key cover 3 is overlapped on the upper end surface of the rear key cover 2, and then Figure 4 As shown, the slot guard 5 is placed around the slot guard hinge 6 and lowered downward so that the slot guard 5 is stacked on the front key cover 3. Figure 5 As shown, the rear key cover 2 is laid down so that the lower end surface of the rear key cover 2 can form a matching inclined surface with the piano case, thereby completing the opening of the entire key cover.

[0038] This technical solution is mainly used on pianos with display screens. In order to increase the space for placing the display screen and avoid the key cover blocking the display screen, the entire key cover is arranged in a folding manner. The key cover is folded and gathered into the piano case, and then the display screen is lowered through the lifting structure, so that the display screen can be close to the piano keys, making the player more comfortable when playing, and also reducing the degree of playing fatigue.

[0039] The rear key cover 2 is L-shaped, and the force of the key cover is concentrated on the intersection of the L shape. The angle design has an arc support to ensure that the rear key cover is not deformed in the length direction and has no twisting.

[0040] The rear key cover 2, the front key cover 3 and the slot block 5 are easy to assemble and can be directly installed by marking, which reduces labor intensity, improves work efficiency and enhances product quality.

[0041] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them in a similar manner without departing from the scope defined by the spirit of the present invention.
