The intelligent grand piano cover comprises a first grand piano cover, a second grand piano cover, a first screen plate, a second screen plate, two supports, two electric push rods and two connecting rod mechanisms, wherein the two supports, the two electric push rods and the two connecting rod mechanisms are distributed on the two sides of the first grand piano cover. The electric push rods are rotatably installed on the corresponding supports, the two sides of the first guitar cover are assembled on the supports and the electric push rods through connecting rod mechanisms, the second guitar cover is rotatably installed on the edge of the first guitar cover, the first screen plate is installed in the first guitar cover, and the second screen plate is movably arranged in the first guitar cover and is close to the second guitar cover. The two sides of the second screen plate are connected with the connecting rod mechanism; when the electric push rod stretches out and draws back, the connecting rod mechanism can be driven to move so as to open and close the first guitar cover, meanwhile, the movement of the connecting rod mechanism can push the second guitar cover to rotate to unfold and close, and the movement of the connecting rod mechanism can drive the second screen plate to move so as to complete stretching out and retracting back. The guitar cover can be automatically opened and closed, and the display function with a comfortable visual angle is achieved.

Description

technical field [0001] The invention relates to the technical field of pianos, in particular to an intelligent cover of a grand piano.

In order to prevent liquids, dust, impurities, foreign objects, etc. from damaging the piano, the role of the piano cover should not be underestimated. It provides protection for the keys and reduces the impact of climate change on the wooden keys. However, the traditional grand piano cover is quite heavy and needs to be opened and closed manually. The keyboard cover and the back cover of the keyboard are usually connected by loose leaves, and there is no damping effect between the loose leaves. When the flip cover is manually lowered, it falls quickly due to gravity, which is easy to damage the piano. The body even smashed the player's fingers. Furthermore, with the development of science and technology, digital inf...

Problems solved by technology

However, the traditional grand piano cover is quite heavy and needs to be opened and closed manually. The keyboard cover and the keyboard back cover are usually connected by a loose leaf, and there is no damping effect between the loose leaves. The body of the piano even hurt the player's fingers

Furthermore, with the development of science and technology, digital information is becoming more and more important. A large number of electronic sheet music, multimedia resources, and teaching software cannot be reasonably presented in front of the performers. They can only be placed on flip covers or pianos with the help of tools such as tablets. , the visual effect is poor, and the height and inclination of the cover are not suitable after the cover is fully opened, which makes the player feel uncomfortable
