[0023] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of the smart piano case provided in one embodiment of this application in one state. Figure 2 for Figure 1 The diagram shows a three-dimensional structural representation of the smart instrument case in another state. It is understood that the instrument case is used to store and protect musical instruments, especially bowed string instruments such as the erhu, violin, and ruan. This application uses an erhu case as an example for illustration. It is understood that the erhu (not shown) includes a body and bow that are fitted together; its specific structure is well known to those skilled in the art and will not be described in detail here.
[0024] The instrument case includes a main body 11, an electronic device assembly 13, and a power management module 15. The main body 11 includes a first main body 111 and a second main body 113 that are movably connected. The first main body 111 and the second main body 113 cooperate to form a receiving space, which is used to accommodate the musical instrument, the electronic device assembly 13, and part of the power management module 15.

It supplies power to the internal electrical devices of the smart piano box 1 through the circuit, and at the same time supplies power to other electronic devices connected to the smart piano box 1, such as mobile phones and handheld fans.
[0026] Please refer to the following: Figure 2 For example, the accommodating space is provided with multiple accommodating slots, including but not limited to a first accommodating slot, a second accommodating slot, a third accommodating slot, a fourth accommodating slot, and a fifth accommodating slot. The instrument body and the bow are accommodated in the first accommodating slot, the interactive terminal 131 is accommodated in the second accommodating slot, the audio output unit 135 is accommodated in the third accommodating slot, the audio input unit 133 is accommodated in the fourth accommodating slot, and the rechargeable power supply 151 is accommodated in the fifth accommodating slot. For heat dissipation and to facilitate charging of the instrument, the fifth accommodating slot and the first accommodating slot are respectively located on the first main body 111 and the second main body 113. In particular, the fifth accommodating slot is correspondingly arranged with the first accommodating slot so that the rechargeable power supply 151 corresponds to the soundbox of the instrument body. For ease of interaction, the second accommodating slot is located near the end of the first main body 111 so that the interactive terminal 131 is installed near the end of the first main body 111. For ease of wiring, the second accommodating slot, the third accommodating slot, and the fifth accommodating slot are arranged adjacent to each other.
[0027] The charging / discharging interface 155 is located on the outer surface of the first body 111 corresponding to the fifth receiving slot. The rechargeable power supply 151, which is housed in the fifth receiving slot, is electrically connected to the charging / discharging interface 155 via a connecting wire to charge an external device or to charge the rechargeable power supply 151 from an external power source.
[0028] It is understood that the charging and discharging interface 155 is a physical interface for inputting electrical energy (charging) and outputting electrical energy (discharging / powering), such as a USB-A interface, a USB-C interface, a DC interface, or an XT60 interface.
[0029] It is understood that the audio input unit 133 refers to a hardware device that can capture sound (sound waves), convert it into electrical signals (analog signals) that can be processed, stored or transmitted by a computer or other digital device, and finally convert it into digital signals, such as a condenser microphone, a dynamic microphone or a ribbon microphone.
[0030] It is understood that the audio output unit 135 is a hardware device that can receive digital audio signals, convert them into analog electrical signals, and ultimately drive physical components to generate sound waves (sound), such as a speaker or a monitor speaker.
[0031] It is understood that the interactive terminal 131 is a human-computer interaction device with a display screen, such as an e-reader, tablet computer, or electronic music reader.
[0032] It is understood that in other embodiments, the first body 111 or the second body 113 may also be provided with more of the aforementioned receiving slots to realize the storage function.
[0033] Please refer to the following: Figure 2 The intelligent piano case 1 also includes a door device 17, which opens and closes like a door to open or close the receiving slot. The door device 17 includes a door body 171 and a handle 173. One end of the door body 171 is movably connected to the first main body 111 and the second main body 113, for example, via a hinge or latch. The opposite end is fixedly connected to the handle 173. The door body 171 opens and closes by pulling the handle 173.
[0034] The receiving slot has an opening on its side or bottom wall, through which the charging / discharging circuit's connecting wires pass to electrically connect to the electronic device assembly 13. In this embodiment, the connecting wire can be a USB cable, with its USB interface located at the opening on the side or bottom wall of the receiving slot. After the components of the electronic device assembly 13 are housed in the receiving slot, the USB interface can be plugged into the USB interface of the electronic device or, using another USB cable, into the USB interfaces of the components of the electronic device assembly 13, thereby enabling the management and control of the charging / discharging process.
[0035] Specifically, the first main body 111 also has an opening 1111, which connects the receiving space and the receiving space. The charging and discharging circuit lines pass through the opening 111 to electrically connect to the instrument body for charging. In this way, the instrument can be charged even when the smart instrument case is in the closed state, making the charging time more reasonable and providing convenience for the performer's outdoor practice.
[0036] For further information, please refer to [link / reference]. Figure 1 The smart piano case 1 also includes a support mechanism 19, which is pivotally connected to the first main body 111 and / or the second main body 113. The support mechanism 19 maintains the piano case in an inclined state relative to the ground.
[0037] The support mechanism 19 includes a first shaft, a second shaft, and a sleeve. One end of the sleeve 195 is pivotally connected to the piano case. The sleeve 195 is sleeved on the first shaft 191. The second shaft 193 is detachably connected to the end of the first shaft 191 away from the sleeve 195.
[0038] It is understood that the sleeve 195 is a tubular structural component with a hollow structure, which can be a round tube, a square tube, or other types of tubular structural components, depending on the actual design requirements. In this embodiment, the sleeve 195 can be a round tube structure, the first shaft 191 can be a circular cylinder structure, and the second shaft 193 can be a square cylinder structure.
[0039] Specifically, please refer to Figure 3 , Figure 3 for Figure 1 The diagram shows an exploded three-dimensional representation of the support mechanism. One end of the sleeve 195 is fixedly connected to a rotating shaft. The extending direction of the rotating shaft 197 intersects the extending direction of the sleeve 195. In this embodiment, the extending direction of the rotating shaft 197 is perpendicular to the extending direction of the sleeve 195. The sleeve 195 is pivotally connected to the outer surface of the first body 111 via the rotating shaft 197.
[0040] The outer surface of the first shaft 191 is provided with a slide rail groove, and the inner wall of the sleeve 195 is provided with a slider (not shown in the figure) corresponding to the slide rail groove. The slider is configured to cooperate with the inner wall of the slide rail groove 1911 with clearance. The advantage of providing the slide rail groove 1911 is that it guides the relative movement between the first shaft 191 and the second shaft 193, and can limit their relative movement within a certain stroke.
[0041] The first shaft 191 is provided with a clearance groove corresponding to the second shaft 193, and the second shaft 193 is partially received in the clearance groove 1913, so that the support mechanism 19 occupies little space, has a simple structure, and is easy to store. It is understood that other clearance designs can be adopted in other embodiments. For example, the clearance groove 1913 can also be provided in the second shaft 193, and the first shaft 191 can be partially received in the clearance groove 1913.
[0042] The first shaft 191, at its end away from the sleeve 195, is pivotally connected to the second shaft 193 via a connector. The first shaft 191 and the second shaft 193 are provided with a first threaded hole and a second threaded hole corresponding to the connector 199. One end of the connector 199 is detachably connected to the first shaft 191 and the second shaft 193 via a threaded connection, while the other end is suspended. In this embodiment, the connector 199 can be a lifting eye bolt. The second shaft 193 is provided with a positioning post, and the first shaft 191 is provided with a corresponding positioning hole. The positioning post 1931 and the positioning hole 1915 are clearance-fitted.
[0043] The second shaft 193 has a first end and a second end along its extension direction, the first end 1933 being inclined relative to its adjacent surface. The second end is provided with a fixing hole, the center line of the fixing hole 1935 being in the same plane as the center line of the positioning post 1931.
[0044] Please refer to the following: Figure 3 and Figure 4 For ease of demonstration of the support mechanism 19, Figure 4 The demonstration is based on the example of the smart piano case 1 being in a closed state. It is understood that the function of the support mechanism 19 is unaffected regardless of the state of the smart piano case 1.
[0045] By assembling and disassembling the connector 199, the support mechanism 19 switches between a first state and a second state. The first state is the state when the support mechanism 19 is not working, and the second state is the state when the support mechanism 19 is working, wherein: In the first state, the extension directions of the sleeve 195, the first shaft 191 and the second shaft 193 are parallel to each other, and the first shaft 191 and the second shaft 193 are detachably connected by the connector 199.
[0046] In the second state, the second shaft 193 rotates at a certain angle relative to the first shaft 191, and the connector 199 is threaded into the first threaded hole and locked in the fixing hole 1935, so that the support mechanism 19 forms a stable T-shaped structure; the sleeve 195, the first shaft 191 and the second shaft 193 rotate synchronously at a certain angle relative to the piano case, and the first end 1933 of the second shaft 193 abuts against the ground to support the piano case.
[0047] In this embodiment, the number of support mechanisms 19 is one. In other embodiments, the number of support mechanisms 19 can be increased according to actual design requirements, and the number is at least one.
[0048] Please combine Figures 1 to 4 The smart piano case 1 is kept tilted relative to the ground by the support mechanism 19, and the interactive terminal 131 is set near the end of the second main body 113, which can provide a more convenient music reading operation for standing playing practice.
[0049] In summary, this application achieves unified power supply for electronic devices and audio equipment inside the guitar case by incorporating a rechargeable battery, solving the problem of users frequently replacing batteries of different specifications and improving power supply efficiency and convenience. A charging interface on the surface of the guitar case allows for external battery replenishment, reducing the frequency of power supply replacements. The power management module's wiring is housed within the internal storage space of the main body, reducing the damage to the circuitry from external dust and moisture. The defined position of the interactive terminal, combined with the changing states of the support mechanism, provides a superior music reading experience.
[0050] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
