[0028] Please refer to the following: Figure 1 , Figure 2 and Figure 3 This application provides a charging case 100, which generally refers to an earphone charging case. The charging case 100 includes a main body 10, a flip cover 20, and a rotating assembly 30 connected between the main body 10 and the flip cover 20. The flip cover 20 is rotatably connected to the main body 10 through the rotating assembly 30 to realize the opening and closing of the charging case 100. When the charging case 100 is closed, a receiving cavity 11 for accommodating earphones (not shown) is formed between the flip cover 20 and the main body 10. When the flip cover 20 is opened, the receiving cavity 11 is exposed, making it easy to take out or put in the earphones.

[0029] The charging case 100 also includes a main circuit board 40, a display screen 50, and a flexible circuit board 60. The main body 10 is provided with a receiving cavity 12 for receiving the main circuit board 40. The rotating component 30 is provided with a transmission channel 31. The display screen 50 is located outside the receiving cavity 11 and is mounted on the flip cover 20. One end of the flexible circuit board 60 is electrically connected to the main circuit board 40, and the other end passes through the transmission channel 31 and is electrically connected to the display screen 50.

[0030] Specifically, the main circuit board 40 is the core control unit of the entire charging case 100, responsible for managing battery power supply, charging status detection, and other functions. The transmission channel 31 within the rotating assembly 30 ensures that the flexible printed circuit board 60 (FPC) is not pulled or damaged during the opening and closing of the flip cover 20, maintaining a stable electrical connection while adapting to the opening and closing action of the flip cover 20. The display screen 50 communicates with the main circuit board 40 via the flexible printed circuit board 60, displaying real-time information such as battery level and earphone connection status. This allows users to intuitively see the usage status of the charging case 100 and the earphone status during use, improving the practicality of the charging case 100.

[0031] In the aforementioned charging case 100, the rotating component 30 is used to open and close the charging case 100, making it easy to put in and take out the earphones. The display screen 50 is integrated on the flip cover 20, allowing users to conveniently use all the functions of the charging case 100 and the earphones through interactive operation with the display screen 50, enriching the functions of the charging case 100 and improving the practicality of the product.

[0032] Please refer to the following: Figure 1 , Figure 2 and Figure 4 In one embodiment, the rotating assembly 30 includes a first connector 32, a second connector 33, and a rotating shaft (not shown). The first connector 32 is connected to the main body 10, and the second connector 33 is disposed on one side of the first connector 32 and connected to the flip cover 20. The rotating shaft rotatably connects the first connector 32 and the second connector 33. The first connector 32 has a first through hole 321, and the second connector 33 has a second through hole 331. The first through hole 321 and the second through hole 331 communicate to form a transmission channel 31.

[0033] Specifically, the pivot is responsible for rotatably connecting the first connector 32 and the second connector 33, so that the first connector 32 and the second connector 33 can rotate smoothly relative to each other, thereby enabling the flip cover 20 to open or close relative to the main body 10.

[0034] Meanwhile, the first through hole 321 of the first connector 32 and the second through hole 331 of the second connector 33 are interconnected, forming a continuous transmission channel 31. The transmission channel 31 provides a safe and unobstructed path for the flexible circuit board 60, allowing the flexible circuit board 60 to extend from inside the main body 10 to the display screen 50 on the flip cover 20, reducing the risk of damage to the flexible circuit board 60 due to the opening and closing action of the flip cover 20.

[0035] Understandably, since the flexible circuit board 60 can pass directly through the transmission channel 31 within the rotating assembly 30 without having to detour through other complex paths, it simplifies the internal wiring of the charging compartment 100, thereby helping to reduce the overall size of the charging compartment 100. The rotating assembly 30 not only provides stable mechanical support but also ensures the stability of electrical connections, improving the overall reliability of the charging compartment 100.

[0036] Meanwhile, the side of the second connector 33 facing away from the first connector 32 is exposed between the main body 10 and the flip cover 20, and the side of the second connector 33 facing away from the first connector 32 is a single, integral structure. This ensures that regardless of whether the main body 10 and the flip cover 20 are in the open or closed state, only the side of the second connector 33 facing away from the first connector 32 is exposed at the connection between the main body 10 and the flip cover 20, and the exposed side is a single, integral structure, thus ensuring the overall integrity of the appearance of the rotating assembly 30.

[0037] In one embodiment, the first connector 32 and the second connector 33 are fabricated using metal injection molding (MIM). In other embodiments, the first connector 32 and the second connector 33 can also be formed using processes such as metal insert injection molding, and no limitation is imposed here.

[0038] In one embodiment, the first connector 32 and the second connector 33 can be integrally formed to have high structural strength.

[0039] In one embodiment, the material of the shaft includes any one of stainless steel, titanium alloy, and aluminum, without limitation.

[0040] Please refer to the following: Figure 2 , Figure 4 , Figure 5 and Figure 6 In one embodiment, the first connector 32 includes a mounting bracket 322 and two first mounting portions 323. The mounting bracket 322 surrounds a first through hole 321, and the outer side of the mounting bracket 322 is provided with a first groove 3221 (see Figure 1). Figure 4The pivot is located in the first groove 3221. Two first mounting parts 323 are spaced apart on both sides of the mounting bracket 322, and the two first mounting parts 323 are used to fix and connect to the side of the main body 10.

[0041] Specifically, the mounting bracket 322 is the core support structure of the first connector 32, and the first through hole 321 on the mounting bracket 322 is used for the flexible circuit board 60 to pass through. The first groove 3221 is used to accommodate the rotating shaft, so that it is stably embedded and realizes the rotation function. The first groove 3221 can also play a limiting and guiding role to ensure that the rotating shaft does not shift laterally during rotation. The dual-point fixing method of the two first mounting parts 323 improves the stability of the connection structure between the first connector 32 and the main body 10, and prevents loosening or displacement caused by single-point force.

[0042] Please refer to the following: Figure 2 and Figure 4 In one embodiment, each first mounting part 323 is provided with at least one first mounting hole 3231, so that screws or other fixing components can pass through the first mounting hole 3231 to fix the first mounting part 323 to the main body 10.

[0043] In this embodiment, the number of first mounting holes 3231 on each first mounting part 323 is two. It can be understood that the number of first mounting holes 3231 on each first mounting part 323 can also be three, four or other numbers, depending on the requirements, and is not limited here.

[0044] In one embodiment, the mounting bracket 322 and the two first mounting parts 323 are integrally formed, which improves the structural strength of the first connector 32.

[0045] Please refer to it again. Figure 2 , Figure 4 , Figure 5 and Figure 6 In one embodiment, the second connector 33 includes a first connecting portion 332 and a second connecting portion 333. The first connecting portion 332 is disposed on one side of the mounting bracket 322 and has a sleeve protrusion 3321 that extends into the first groove 3221 and is sleeved on the outside of the rotating shaft. The side of the first connecting portion 332 facing away from the mounting bracket 322 has a second groove 3322. The second connecting portion 333 is connected to the side of the first connecting portion 332 facing away from the mounting bracket 322, and a second through hole 331 is formed between the surface of the second connecting portion 333 facing the first connecting portion 332 and the second groove 3322.

[0046] Specifically, the sleeve protrusion 3321 on the first connecting part 332 can have a through hole or an annular structure inside and be sleeved on the outside of the rotating shaft to form a rotational fit to achieve a rotatable connection between the flip cover 20 and the main body 10. The rotating shaft passes through the first groove 3221 of the mounting bracket 322 and is wrapped by the sleeve protrusion 3321 of the first connecting part 332, achieving a stable rotational connection between the flip cover 20 and the main body 10. At the same time, the surface of the second connecting part 333 facing the first connecting part 332 is opposite to the second groove 3322 on the first connecting part 332, forming a complete second through hole 331 between them for the flexible circuit board 60 to pass through.

[0047] It is understandable that the first through hole 321 in the first connector 32 and the second through hole 331 in the second connector 33 form a complete transmission channel 31 for the flexible circuit board 60. The flexible circuit board 60 starts from the main circuit board 40, enters the second through hole 331 through the first through hole 321, and finally connects to the display screen 50 on the flip cover 20, realizing the electrical connection between the display screen 50 and the main circuit board 40.

[0048] Meanwhile, the side of the second connecting part 333 facing away from the first connecting part 332 is exposed between the main body 10 and the flip cover 20, and the side of the second connecting part 333 facing away from the first connecting part 332 is an integral, one-piece structure. This ensures that regardless of whether the main body 10 and the flip cover 20 are in the open or closed state, only the side of the second connecting part 333 facing away from the first connecting part 332 is exposed at the connection between the main body 10 and the flip cover 20, and the exposed side is an integral, one-piece structure, thus ensuring the appearance integrity of the rotating assembly 30.

[0049] Please refer to it again. Figure 2 and Figure 4 In one embodiment, a second mounting portion 3323 is provided at each end of the first connecting portion 332. Each second mounting portion 3323 is provided with at least one second mounting hole 3324 so that screws or other fixing components can pass through the second mounting hole 3324 to fix the second mounting portion 3323 to the flip cover 20.

[0050] In this embodiment, the number of second mounting holes 3324 on each second mounting part 3323 is two. It can be understood that the number of second mounting holes 3324 on each second mounting part 3323 can also be three, four or other numbers, depending on the requirements, and is not limited here.

[0051] In one embodiment, the first connecting part 332 and the second connecting part 333 are integrally formed, thereby improving the structural strength of the second connecting part 33.

[0052] Please refer to the following: Figure 1 , Figure 2 and Figure 4 In one embodiment, the rotating assembly 30 further includes an elastic element 34 connected between the first connector 32 and the second connector 33 to limit the rotation angle of the second connector 33 relative to the first connector 32. The elastic element 34 provides resistance when the flip cover 20 is opened to a preset angle, preventing further rotation and improving the stability of the charging case 100 during the opening and closing processes.

[0053] In one embodiment, the elastic element 34 includes a torsion spring. In other embodiments, the elastic element 34 may also include a tension spring, a compression spring, etc., depending on the requirements, and is not limited here.

[0054] In one embodiment, when the elastic element 34 is a torsion spring, the dividing point of the force generated by the torsion spring is between 30 and 40 degrees when the opening angle of the flip cover 20 is less than 30 degrees. That is, when the opening angle of the flip cover 20 is less than 30 degrees, the spring force provided by the torsion spring is relatively small, allowing the user to easily control the opening and closing speed of the flip cover 20 and avoid the flip cover 20 suddenly opening or closing due to excessive spring force. When the opening angle of the flip cover 20 is between 30 and 40 degrees, the spring force of the torsion spring increases, helping the flip cover 20 to reach the fully open position more smoothly. When the opening angle of the flip cover 20 exceeds 40 degrees, the torsion spring may no longer provide additional spring force, or the spring force provided may tend to stabilize, in order to prevent excessive force from damaging the structure.

[0055] Please refer to the following: Figure 3 , Figure 7 and Figure 8 In one embodiment, the main body 10 includes a bottom surface 13 and a first side surface 14, a second side surface 15, a third side surface 16, and a fourth side surface 17 arranged around the bottom surface 13 and connected end to end. The first side surface 14 and the third side surface 16 are arranged opposite each other along a first direction X, and the second side surface 15 and the fourth side surface 17 are arranged opposite each other along a second direction Y. The first side surface 14 is rotatably connected to the flip cover 20 via a rotating assembly 30. The first direction X and the second direction Y are perpendicular to each other. The bottom surface 13, the first side surface 14, the second side surface 15, the third side surface 16, and the fourth side surface 17 form a semi-enclosed shell structure of the main body 10.

[0056] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 7 In one embodiment, the charging case 100 further includes two sets of microphone assemblies 70, respectively mounted on a first side 14 and a third side 16 of the main body 10, and the microphone assemblies 70 are electrically connected to the main circuit board 40. The two sets of microphone assemblies 70 help to capture sound signals from different directions, providing a more comprehensive sound coverage.

[0057] In one embodiment, each microphone assembly 70 includes two microphones, namely four microphones on the first side 14 and the third side 16, making the recorded sound source clearer.

[0058] Please refer to the following: Figure 1 , Figure 2 and Figure 8 In one embodiment, the charging case 100 further includes a speaker 80 mounted on the second side 15 of the main body 10 and electrically connected to the main circuit board 40. The speaker 80 enables the charging case 100 to play audio, enhancing the interaction between the user and the charging case 100, making operation more intuitive and convenient, and further improving the practicality of the charging case 100.

[0059] Please refer to it again. Figure 1 , Figure 2 and Figure 7 In one embodiment, the charging case 100 further includes a power button 90, which is installed on the first side 14 of the main body 10 and spaced apart from the microphone assembly 70. The power button 90 is electrically connected to the main circuit board 40 and is used to control the opening or closing of the charging case 100 under external triggering, thereby achieving the purpose of starting or closing the entire charging case 100.

[0060] Please refer to it again. Figure 1 , Figure 2 and Figure 3 In one embodiment, the charging case 100 further includes an interface 101 mounted on the fourth side 17 of the main body 10. The interface 101 is electrically connected to the main circuit board 40 and is used to connect to external devices.

[0061] In one embodiment, interface 101 may be a charging interface, allowing a user to replenish power to the charging case 100 itself.

[0062] In another embodiment, the interface 101, which serves as a charging port, can also be reused as a digital interface to support data transmission between the charging case 100 and external devices.

[0063] Please refer to the following: Figure 1 , Figure 3 , Figure 7 , Figure 8 and Figure 9 This application provides a wireless earphone 200, which includes earphones and the aforementioned charging case 100.

[0064] The aforementioned earphones support Bluetooth or other wireless communication protocols and have audio playback functions. The charging case 100 used with the earphones has storage and charging functions, and integrates intelligent modules such as display screen 50, microphone component 70, speaker 80, power button 90, and interface 101. It supports multiple functions such as human-computer interaction, voice control, and external device connection, improving the practicality of the wireless earphones 200.

[0065] In one embodiment, when the wireless earphone 200 is a translation earphone, the microphone assembly 70 on the charging case 100 is used to capture clear sound signals to ensure translation accuracy, especially when two-way or multi-way translation is required. The speaker 80 ensures that the translation result is clearly conveyed to the user and can also be used to play the translated speech. The display screen 50 on the charging case 100 can be used to display information such as the current translation status, making it easy for the user to intuitively understand the translated content.

[0066] Specifically, the charging case 100 in the wireless earbuds 200 can realize core functions such as voice translation, external sound playback, and voice display after translation. At the same time, it can also charge the earbuds and improve the battery life of the wireless earbuds 200.

[0067] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
