[0025] Currently, wireless Bluetooth headphones have become a mainstream accessory for portable audio devices. Their accompanying charging cases are primarily used to store and charge the headphones, serving only as simple charging and storage devices. While the user is wearing the Bluetooth headphones, the charging case is usually not in use and still needs to be carried by the user for later storage and charging.

[0026] However, existing Bluetooth headphone cases have relatively limited functions, only providing basic storage and charging. They cannot offer other auxiliary functions when users are wearing headphones, and they are difficult to integrate with users' daily usage scenarios. As a result, the utilization rate of headphone cases is low, and the overall structure and functional design fail to fully meet users' diverse and convenient usage needs, which to some extent limits the user experience and application scenario expansion of the product.

[0027] The main objective of this invention is to provide an earphone charging case 100 that addresses the problems of existing Bluetooth earphone cases having limited functionality, serving only as storage and charging devices, low utilization when idle, and failing to meet diverse user needs.

The first connecting part 21 is connected to the earphone case 1 in a detachable manner. This connection can be in the form of magnetic mating, snap-fit, plug-in mating, or rotational snap-fit. The first connecting part 21 and the corresponding structure on the earphone case 1 are mutually compatible. After connection, the camera 2 can be stably positioned on the earphone case 1, preventing shaking or loosening. The assembly and disassembly process does not require additional tools, enabling quick assembly and separation between the camera 2 and the earphone case 1. By setting a dedicated first connecting part 21 at one end of the camera 2, a stable and reliable mating relationship is formed between the camera 2 and the headphone box 1. This ensures that the camera 2 is not easily loosened or detached when stored or used, and also enables quick assembly and disassembly, improving the flexibility of use. At the same time, the first connecting part 21 does not occupy the lens area and does not affect the camera function, further improving the structural stability and reliability of the product.

[0036] Please see Figure 1 , Figure 3 and Figure 4 In one embodiment of the present invention, a second connecting part 12 is provided in the receiving groove 11, and a first connecting part 21 is embedded in the receiving groove 11 and connected to the second connecting part 12.

[0037] In this embodiment, the second connecting part 12 is an integrally formed or fixedly embedded structure of the inner wall of the receiving groove 11. The whole can be constructed as a groove, boss, snap-fit ​​seat, magnetic component or conductive contact structure. Its shape is adapted to the first connecting part 21. It is set inside the receiving groove 11 without occupying the receiving space of the camera 2, and without damaging the integrity of the inner wall of the receiving groove 11. The first connecting part 21 is embedded in the receiving groove 11 and connected to the second connecting part 12. After the first connecting part 21 extends into the receiving groove 11, it forms a matching fit with the second connecting part 12. The two achieve a stable connection through plugging, snapping, magnetic attraction or conductive abutment. After connection, the camera 2 is confined in the receiving groove 11 and will not rotate circumferentially or move radially. The disassembly and assembly process can be completed without tools, and the connection state is stable and reliable. By embedding the first connecting part 21 into the receiving groove 11 and cooperating with the second connecting part 12, the camera 2 is hidden, making the camera 2 fit the headphone case 1 more closely and resulting in a cleaner and more streamlined appearance. The internal connection method effectively protects the first connecting part 21 and the second connecting part 12, reducing damage from external impacts and dust, and improving structural durability. Simultaneously, the embedded fit offers higher positioning accuracy and faster assembly, further enhancing the stability and safety of the camera 2 after installation. In another embodiment, please refer to... Figure 1 and Figure 3 To facilitate the removal of the camera 2 from the receiving slot 11, an annular groove is formed around the opening of the receiving slot 11. A ring block is formed at the end of the camera 2 away from the first connecting part 21, which is exposed in the opening of the annular groove. The ring block will not block the shooting area of ​​the camera 2. When the camera 2 needs to be removed, the user can insert his / her fingers into the annular groove and pinch the ring block to remove the camera 2. The setting of the annular groove ensures that the camera 2 does not protrude from the surface of the headphone box 1 after being received in the receiving slot 11, thus ensuring the overall neatness of the headphone box 1.

[0038] Please see Figure 1 , Figure 3 and Figure 4 In one embodiment of the present invention, the earphone housing 1 is provided with a power supply unit 13, the receiving groove 11 is provided with a power supply unit 13 electrically connected to the power supply unit 13, and the side wall of the camera 2 facing the receiving groove 11 is formed with a charging unit 22. The power supply unit 13 and the charging unit 22 abut against each other to charge the camera 2.

[0039] In this embodiment, the power supply unit 13 is an energy storage and power supply structure located inside the earphone case 1. It can be constructed using a lithium battery cell with stable power supply performance combined with an insulating protective shell. The overall structure is block-shaped and does not occupy the receiving slot 11 or the earphone storage area. It can provide stable power output to the earphone case 1 itself and external electrical components without compromising the internal structural layout and overall strength of the earphone case 1. The receiving slot 11 is equipped with the power supply unit 13, which is electrically connected to the power supply unit 13. The power supply unit 13 is a conductive structure embedded in the inner wall of the receiving slot 11. It is made of a metal material with excellent conductivity and oxidation resistance, and can be constructed as conductive bumps, conductive springs, or conductive planes. Electrical connection is achieved through concealed wires. The power supply unit 13 does not protrude from the inner wall of the receiving slot 11, does not affect the embedded assembly of the camera 2, and can stably transmit power without being easily affected by external interference. A charging section 22 is formed on the side wall of the camera 2 facing the receiving groove 11. This charging section 22 is a conductive mating structure formed on the side of the camera 2 facing the receiving groove 11. The material is compatible with the power supply section 13, and it is also made of a conductive and stable metal material. Its shape corresponds to and matches the structure of the power supply section 13. It is set on the side wall of the camera 2, without occupying the lens area and without interfering with the normal operation of the shooting function. The power supply section 13 and the charging section 22 abut against each other so that the power supply section 13 charges the camera 2. When the camera 2 is installed in the receiving groove 11, the power supply section 13 and the charging section 22 automatically form a close-fitting conductive contact, and power conduction can be achieved without additional plugging or manual wiring. The abutment fit is stable and the contact is reliable. The charging docking is completed simultaneously when the camera 2 is fixed, and the power supply is automatically disconnected when separated. By setting corresponding power supply units 13 and charging units 22 on the earphone case 1 and camera 2 respectively, automatic charging is achieved by utilizing the natural contact during assembly of the receiving slot 11, eliminating the need for additional charging cables or charging bases, greatly improving the ease of use and battery life of the camera 2; both the power supply and charging structures are hidden, without compromising the overall appearance and structural compactness of the product, while the contact-type conductive joint has high stability and long service life, enabling the earphone case 1 to not only perform storage, charging, and camera functions, but also further support the battery life of the camera 2, realizing the multi-functional integration of the earphone case 1, and greatly improving the product's practicality and user experience.

[0040] Please see Figure 1 , Figure 2 and Figure 5 In one embodiment of the present invention, the earphone case 1 has a shooting side 14 and a supporting side 15, which are arranged opposite to each other; the shooting side 14 is provided with a camera 2; the supporting side 15 is provided with a supporting part 16, which is rotatably connected to the earphone case 1.

[0041] In this embodiment, the shooting side 14 and the supporting side 15 are two oppositely arranged sides of the earphone case 1. They are positioned at different locations on the earphone case 1, forming a relatively distributed structural layout. This layout can reasonably distinguish between functional areas and supporting areas, avoiding interference between different functional structures, while maintaining the overall balance and regularity of the earphone case 1. The shooting side 14 is equipped with a camera 2. As the functional area of ​​the earphone case 1, the shooting side 14 provides a stable mounting surface for the camera 2. Positioning the camera 2 on this side allows the lens to face the target shooting direction, ensuring an unobstructed field of view. The shooting area and the supporting area are independent of each other, so that the movement of the supporting part 16 will not interfere with the normal shooting operation of the camera 2. The supporting side 15 is equipped with a supporting part 16, which is an auxiliary support structure for the earphone case 1. The supporting part 16 can be made of rigid engineering plastic with structural strength or lightweight metal, and its overall structure is plate-shaped or block-shaped. Located on the supporting side 15 opposite to the shooting side 14, it does not occupy the functional space of the shooting side 14, nor does it affect the assembly and use of the camera 2. The support part 16 is rotatably connected to the earphone case 1. The support part 16 forms a rotatable engagement with the earphone case 1 through a pivot or hinge structure. The rotatable connection structure is hidden inside or on the side edge of the earphone case 1 and does not protrude from the outer contour of the earphone case 1. The support part 16 can be flipped, unfolded, or its angle adjusted relative to the earphone case 1. The rotation process is smooth and the positioning is reliable. It can fit snugly against the earphone case 1 when stored and unfold to form a supporting posture when in use. By dividing the earphone case 1 into a shooting side 14 and a supporting side 15, a separate layout of the functional area and the supporting area is achieved. This ensures that the shooting of the camera 2 is not disturbed and that the support part 16 can stably perform its supporting function. The rotatable connection design of the support part 16 allows the earphone charging case 100 to be placed independently and the shooting angle to be adjusted. Fixed shooting can be achieved without holding the earphone, expanding the usage scenarios for selfies, videos, live streaming, etc. When not in use, the support part 16 can be folded up and fitted snugly against the earphone case 1 without increasing the overall size, maintaining the portability of the product, and further improving the practicality and user experience of the product.

[0042] In one embodiment of the present invention, at least a portion of the structure of the support portion 16 is detachably disposed on the earphone housing 1 and is connected in cooperation with the first connecting portion 21.

[0043] In this embodiment, at least a portion of the structure of the support part 16 is detachably disposed on the earphone case 1. This portion of the structure is a connecting section on the support part 16 for cooperating with the earphone case 1. Its shape is adapted to the corresponding assembly area on the earphone case 1. It can be detachably assembled by means of plugging, snapping or magnetic attraction. When not in use, the partial structure of the support part 16 can be removed without occupying the external space of the earphone case 1 or affecting the appearance integrity of the earphone case 1. The detachable connecting structure is connected to the first connecting part 21. The first connecting part 21 is a special mating structure on the camera 2 for docking with the second connecting part 12 in the receiving slot 11 of the earphone box 1. The two adopt the same type of matching mating form. After the detachable connecting section of the support part 16 is removed, it can be directly and quickly aligned with the first connecting part 21 on the camera 2. It forms a stable lock by relying on magnetic attraction or limit locking. After mating, the support part 16 and the camera 2 are connected as one, with no relative displacement and no loosening or shaking. Moreover, the docking position completely avoids the lens area of ​​the camera 2, so it does not obstruct the shooting field of view or interfere with the imaging effect, ensuring the normal and stable operation of the camera function. By making the partial structure of the support part 16 detachable and adapting it to the first connecting part 21 on the camera 2, the support part 16 can be used for multiple purposes, greatly improving the utilization rate of the internal components of the product. When the structure is installed on the earphone case 1, it can be used as the support part 16 to support the earphone charging case 100 at multiple angles, adapting to the needs of fixed-point shooting and handheld use. After disassembly, it can be used directly as the independent adapter and fixing part 411 of the camera 2. The camera 2 can be flexibly attached and fixed to various flat or flexible carriers such as clothing, backpacks, and desktops with the help of the support part 16, further expanding the scenarios for the standalone use of the camera 2 and meeting diverse needs such as outdoor, daily casual shooting, and fixed shooting.

[0044] Please see Figure 2 In one embodiment of the present invention, the support part 16 includes a connecting block 161 and a mounting block 162. The connecting block 161 and the mounting block 162 are detachably connected. The connecting block 161 is connected to the first connecting part 21. The mounting block 162 is rotatably connected to the earphone box body 1.

[0045] In this embodiment, the support part 16 includes a connecting block 161 and a mounting block 162. The connecting block 161 and the mounting block 162 are two independent functional components of the support part 16, both made of hard engineering plastic with reliable structural strength and wear resistance. Their shapes are compatible with each other, forming the complete structure of the support part 16. They respectively undertake the functions of docking with the camera 2 and rotating with the earphone box 1, making the support part 16 a modular combination structure. The connecting block 161 and the mounting block 162 are detachably connected. They can be separable by means of buckles, plugs, or magnetic attraction. After connection, the whole is stable and does not loosen. Disassembly can be done manually without the aid of tools, which is convenient for using one of the components alone, and also convenient for maintenance, replacement, or flexible combination according to the usage scenario. The connecting block 161 is connected to the first connecting part 21. The connecting block 161 has a docking structure that matches the first connecting part 21 on the camera 2. The two can be stably docked by plugging, snapping, or magnetic attraction. After connection, the support part 16 can be used as an independent support or mounting structure for the camera 2 without obstructing the lens or affecting shooting. Even after the camera 2 is detached from the headphone box 1, it can still achieve stable support for shooting. The mounting block 162 is rotatably connected to the headphone box 1. The mounting block 162 forms a rotatable engagement with the headphone box 1 through a hinge or pivot structure. The rotatable structure is hidden and does not damage the outer contour of the headphone box 1. The mounting block 162 can be flipped open or folded close relative to the headphone box 1 to provide stable support for the headphone box 1 and realize multi-angle shooting. By dividing the support part 16 into a modular and detachable structure consisting of a connecting block 161 and a mounting block 162, the support part 16 simultaneously serves the dual functions of supporting the earphone case 1 and independently supporting the camera 2, achieving multiple uses and significantly improving component utilization. The connecting block 161 can cooperate with the first connecting part 21 on the camera 2, allowing the camera 2 to obtain stable support when used alone, meeting the needs of handheld shooting and multi-angle shooting. The mounting block 162 is rotatably connected to the earphone case 1, ensuring that the earphone case 1 can be stably placed and used. The overall structure is flexible and easy to assemble and disassemble, further expanding shooting scenarios and improving product practicality and user experience.

[0046] Please see Figure 6 In one embodiment of the present invention, the support side 15 is provided with a third connecting part 17, which is connected to the connecting block 161.

[0047] In this embodiment, the support side 15 is provided with a third connecting part 17. The third connecting part 17 is a mating structure provided on the support side 15 of the earphone case 1. It can be constructed as a boss, groove, snap-fit ​​position or magnetic mating surface structure. It is arranged in the preset assembly area of ​​the support side 15, does not protrude from the outer contour of the earphone case 1, and does not interfere with the rotating structure, receiving groove 11 or other components of the support side 15. The third connecting part 17 is mated with the connecting block 161. The two adopt a positioning and detachable mating form. The connecting block 161 can form a stable docking with the third connecting part 17 by embedding, snapping or magnetic adsorption. After assembly, the connecting block 161 and the earphone case 1 are relatively fixed and will not loosen or shift. It provides a reliable connection base for the entire support part 16. At the same time, the disassembly and assembly process does not require tools and can realize quick assembly and separation. By setting a dedicated third connecting part 17 on the support side 15, a precise and stable docking relationship is formed between the connecting block 161 and the earphone box 1, which further improves the overall firmness of the support part 16 after installation and prevents the support part 16 from shaking or falling off during rotation or support.

[0048] In one embodiment of the present invention, the connection areas of the third connecting part 17 and the connecting block 161 are both larger than the connection area of ​​the first connecting part 21.

[0049] In this embodiment, the contact surface between the third connecting part 17 and the connecting block 161 has a larger contact area in its structural layout. The outline shape of this contact area is adapted to the shape of the support side 15 and the connecting block 161, which can form a large-area fit and docking. Moreover, the overall distribution position avoids the assembly area of ​​the camera 2 and the receiving groove 11, and does not interfere with other functional structures. The third connecting part 17 and the connecting block 161 cooperate with each other through a larger contact area. The contact range between the two is wider, which can form a stable and reliable cooperation relationship. During the unfolding, rotation or support force of the support part 16, the whole remains stable and there will be no loosening, swaying or slippage. At the same time, this larger connection area forms a structural distinction from the first connecting part 21, each undertaking its corresponding connection function without affecting each other. By setting the connection area between the third connecting part 17 and the connecting block 161 to be larger than the connection area of ​​the first connecting part 21, the connection strength and stability between the support part 16 and the earphone box 1 can be effectively improved. When the support part 16 bears the supporting force, the force is dispersed, avoiding local stress concentration that could cause component deformation or damage. The larger connection area can reduce the difficulty of assembly alignment and improve the ease of disassembly and assembly. At the same time, it ensures the reliable and stable support function and does not interfere with the normal docking of the camera 2 and the first connecting part 21. This allows the overall structure to achieve multi-angle support shooting while having higher durability and safety of use.
