Description

Technical Field

[0001] The utility model belongs to the technical field of musical instruments, and particularly relates to a piano cover buffer structure and a piano. Background Art

[0002] Electronic musical instruments such as digital pianos and electronic organs are widely used in music creation. These electronic musical instruments are usually equipped with a flip-up piano cover for covering or exposing components such as the required console or keyboard. In actual use, users need to frequently open or close the piano cover to adjust the playing state. However, in the prior art, when the front cover is flipped up, the front cover and the rear cover cannot be flush, and when using a buffer mechanism, the installation structure of the buffer mechanism is complex and difficult to debug. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a piano cover buffer structure and a piano, which are mainly used to solve the defects such as the front cover not being flush with the rear cover after being flipped up and the complex installation of the buffer mechanism in the prior art.

[0004] To solve the above problems, the technical solutions adopted by the utility model are as follows:

[0005] In a first aspect, the utility model provides a piano cover buffer structure, including:

[0006] A piano body fixed bracket;

[0007] A rear cover, fixed to the top of the piano body fixed bracket;

[0008] A front cover, whose left and right ends are respectively connected to the sides of the piano body fixed bracket through a buffer bracket module, and the rear end of the front cover is hinged to the rear cover;

[0009] The buffer bracket module includes a double-rotating shaft connection component and a damper. The damper is connected to the side of the piano body fixed bracket. One end of the double-rotating shaft connection component is connected to the damper, and the other end is connected to the bottom of one end of the front cover. The double-rotating shaft connection component rotates around its double-rotating shaft by its own structure when the front cover is flipped.

[0010] In some embodiments, the double-rotating shaft connection component includes a first bracket, a second bracket, and a third bracket;

[0011] The first end of the first bracket is connected to the damper, and the second end is rotatably connected to the first end of the second bracket through a rivet column structure;

[0012] The second bracket includes an adjacent straight section and arc section. The straight section is connected to the first bracket, and the arc section is connected to the third bracket;

[0013] The first end of the third bracket is rotatably connected to the end of the arc segment through a rivet column structure, and the second end is fixed to the bottom of one end of the front cover plate.

[0014] In some embodiments, the length of the arc segment is greater than the length of the straight line segment.

[0015] In some embodiments, the damper is an adjustable damping device.

[0016] In a second aspect, the utility model provides a piano, comprising a piano cover buffer structure as described above.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] The front cover is connected to the piano body fixing bracket through the buffer bracket modules at both ends. By using the buffer bracket module to buffer the opening and closing action of the front cover, the front cover can be smoothly turned over. In addition, most of the buffer bracket module is hidden in the side of the piano body fixing bracket, and a small part of the structure is exposed at the bottom of both ends of the front cover, which has good concealment.

[0019] Through the design of the double-shaft connecting assembly, the double-shaft connecting assembly itself can rotate around the double shafts during the flipping process of the front cover, which greatly reduces the friction resistance during the movement of the front cover;

[0020] The arc segment design of the second bracket further optimizes the flipping trajectory of the front cover, making it smoother.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] In the description of the present invention, when it is described that a specific device is located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When it is described that a specific device is connected to other devices, the specific device may be directly connected to other devices without an intermediate device, or may not be directly connected to other devices but have an intermediate device.

[0031] For technologies, methods, and devices known to those of ordinary skill in the relevant fields, they may not be discussed in detail, but in appropriate cases, the technologies, methods, and devices should be regarded as part of the specification.

[0032] Referring to Figures 1 to 5 , in a first aspect, the present embodiment provides a piano cover buffer structure, including:

[0033] A piano body fixed bracket 1, with piano keys arranged directly in front of the piano body fixed bracket 1;

[0034] A rear cover plate 2, fixed to the top of the piano body fixed bracket 1, and the rear cover plate 2 does not displace when the front cover plate 3 is flipped;

[0035] A front cover plate 3, which is in the shape of a long plate, and its left and right ends are respectively connected to the sides of the piano body fixed bracket 1 through buffer bracket modules 4, and the rear end of the front cover plate 3 is hinged to the rear cover plate 2;

[0036] The buffer support module 4 includes a double-rotating shaft connection component 41 and a damper 42. The damper 42 is connected to the side of the body fixing bracket 1. One damper 42 is connected to each of the left and right sides of the body fixing bracket 1. One end of the double-rotating shaft connection component 41 is connected to the damper 42, and the other end is connected to the bottom of one end of the front cover 3. A part of the double-rotating shaft connection component 41 near the damper 42 is hidden under the rear cover 2, and only a part of the double-rotating shaft connection component 41 near the front cover 3 is exposed. The double-rotating shaft connection component 41 has two rotating shafts and is of a multi-section structure. When the front cover 3 is flipped, the structure of the double-rotating shaft connection component 41 rotates around its double rotating shaft 43 by itself.

[0037] As Figure 2 shown, when closing the cover, most of the double-rotating shaft connection component 41 shrinks under the rear cover 2 and on the side of the body fixing bracket 1; as Figure 3 shown, when flipping the cover, a part of the double-rotating shaft connection component 41 is exposed. It can be seen that, in terms of the structure of the double-rotating shaft connection component 41 itself, there are two rotation axes for rotation.

[0038] Referring to Figure 4 and Figure 5 , specifically, the double-rotating shaft connection component 41 includes a first bracket 51, a second bracket 52, and a third bracket 53;

[0039] The first end of the first bracket 51 is connected to the damper 42, and the second end is rotatably connected to the first end of the second bracket 52 through a rivet column structure 6;

[0040] The second bracket 52 includes an adjacent straight segment 54 and an arc segment 55. The straight segment 54 is connected to the first bracket 51, and the arc segment 55 is connected to the third bracket 53;

[0041] The first end of the third bracket 53 is rotatably connected to the end of the arc segment 55 through a rivet column structure 6, and the second end is fixed to the bottom of one end of the front cover 3.

[0042] It should be noted that through the design of the double-rotating shaft connection component 41, during the flipping process of the front cover 3, the structure of the double-rotating shaft connection component 41 itself can rotate around the double rotating shaft 43, that is, rotation will occur between the first bracket 51 and the second bracket 52, and between the second bracket 52 and the third bracket 53, greatly reducing the frictional resistance during the movement of the front cover 3 and improving the smoothness of the opening and closing of the front cover 3; further, through the rivet column structure 6, by making good use of the combination of the rivet column, gasket, and press riveting process, the effect of no friction, no jamming, and no noise between the brackets can be achieved.

[0043] As an implementation manner, the length of the arc segment 55 is greater than that of the straight segment 54. The design of the arc segment 55 of the second bracket 52 further optimizes the flipping trajectory of the front cover plate 3, making it smoother and more fluent, reducing the vibration and impact during the opening and closing process. Moreover, since the length of the arc segment 55 is greater than that of the straight segment 54, by reasonably utilizing the lever principle, the force is transmitted to the damper 42, achieving a good damping and buffering effect.

[0044] As an implementation manner, the damper 42 is an adjustable damping device. The adjustable damper 42 enables the user to adjust the opening and closing speed of the front cover plate 3 according to requirements, improving the usage flexibility and meeting the requirements of different usage scenarios.

[0045] In a second aspect, this embodiment provides a piano, including a piano cover buffering structure as described in the above embodiment.

[0046] Optionally, this piano is a digital piano.

[0047] In summary, compared with the prior art, the above embodiment provides a piano cover buffering structure and a piano. The front cover plate 3 is connected to the piano body fixed bracket 1 through the buffer bracket modules 4 at both ends. By using the buffer bracket modules 4 to buffer and control the opening and closing actions of the front cover plate 3, the smooth flipping of the front cover plate 3 can be realized. Moreover, most of the buffer bracket modules 4 are hidden on the side of the piano body fixed bracket 1, and a small part of the structure is exposed at the bottom of both ends of the front cover plate 3, with good concealment;

[0048] Through the design of the double-rotating shaft connection component 41, during the flipping process of the front cover plate 3, the structure of the double-rotating shaft connection component 41 itself can rotate around the double-rotating shaft 43, greatly reducing the frictional resistance during the movement of the front cover plate 3;

[0049] The design of the arc segment 55 of the second bracket 52 further optimizes the flipping trajectory of the front cover plate 3, making it smoother and more fluent.

[0050] The above implementation manners are only the preferred implementation manners of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
