Additionally, during assembly, internal components (such as batteries and circuit boards) can be installed into the middle frame first, followed by the installation of the first and second panels on either side of the middle frame. This assembly method is intuitive and simple, greatly reducing assembly difficulty and time. Moreover, due to the stability of the sandwich structure, the assembled earphone charging case exhibits better structural strength and durability. Attached Figure Description

[0038] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] Existing flip-top wireless earphone cases are popular for their convenient opening and closing design and comprehensive protection of the earphones. However, the earphones occupy most of the space inside the case, which limits the size of the battery and thus affects the battery capacity and battery life. At the same time, the overall size of the earphone case is relatively large, which is not conducive to portability.

[0042] To overcome the above technical problems, refer to Figures 5-12 This embodiment provides an earphone charging case 1, including a shell 11. The shell 11 includes a middle frame 111, a first panel 112 and a second panel 113. The first panel 112 and the second panel 113 are respectively installed on the two open sides of the middle frame 111. A device mounting cavity 115 is formed in the inner cavity of the middle frame 111. Two earphone placement slots 114 are formed on the outer periphery of the middle frame 111.

[0043] In this embodiment, the earphone charging case 1 can be used to store earphones 2 and also to charge earphones 2. Therefore, circuit boards, batteries 12, and other necessary charging components will be installed in the component mounting cavity 115 of the outer shell 11.

[0044] The middle frame 111 is specifically a frame structure with a central cavity, so as to... Figure 6 In the position shown, the entire earphone charging case 1 is laid flat, and the cavity in the middle of the middle frame 111 is open from top to bottom. Openings of the cavity are formed on the upper and lower sides of the middle frame 111, respectively. Therefore, the first panel 112 and the second panel 113 cover the upper and lower sides of the middle frame 111 and close the openings on the upper and lower sides of the cavity, thereby forming a closed device mounting cavity 115 inside the housing, providing support, fixation, isolation, dustproof and waterproof protection for various devices installed inside.

[0045] An earphone placement slot 114 is provided on the outer periphery of the middle frame 111 to accommodate the earphone 2. After the earphone 2 is placed, it will not occupy the space inside the outer shell 11, so there is more space inside the outer shell 11 to accommodate various devices such as the battery 12.

[0046] In summary, based on the earphone charging case 1 provided in this embodiment, its outer shell 11 includes a middle frame 111, a first panel 112, and a second panel 113. The middle frame 111 and the first and second panels 112 on both sides form a device mounting cavity 115 for mounting the battery 12 and related circuit boards and other devices. Furthermore, by designing the earphone placement slot 114 on the outer periphery of the middle frame 111, rather than traditionally occupying the entire internal space, more ample installation space is provided for key components such as the battery 12. This not only effectively solves the problem of limited battery 12 volume but also increases the battery 12 capacity, thereby extending the overall battery life of the earphone 2 and the earphone 2 charging case, meeting the user's need for long-term use. The improved design, through a more compact layout, allows the earphone charging case 1 to reduce its overall size while maintaining sufficient internal space.

[0047] Furthermore, the outer shell 11 of this design adopts a sandwich structure consisting of a first panel 112, a middle frame 111, and a second panel 113. The manufacturing process allows for the separate molding of the first panel 112, the middle frame 111, and the second panel 113, followed by assembly. Due to the simpler structure and lower demolding difficulty, efficient injection molding can be used for processing. This not only improves production efficiency but also significantly reduces processing costs. Injection molding offers advantages such as fast molding speed, high precision, and mass production capability, making it ideal for processing this sandwich structure outer shell 11. Additionally, during assembly, internal components (such as the battery 12 and circuit boards) can be installed into the middle frame 111 first, followed by the installation of the first panel 112 and the second panel 113 onto the sides of the middle frame 111. This assembly method is intuitive and simple, greatly reducing assembly difficulty and time. Moreover, due to the stability of the sandwich structure, the assembled earphone charging case 1 exhibits better structural strength and durability.

[0048] In one embodiment, reference is made to Figure 9 and Figure 10 The headphone placement slot 114 includes a head placement area 1141 and a head placement area 1142. The first panel 112 and the second panel 113 respectively include a main body 1121 and a side edging 1122 connected to the side of the main body 1121. The main body 1121 is adapted to form the device mounting cavity 115 by enclosing the middle frame 111. The side edging 1122 extends to the outer periphery of the middle frame 111 and covers the head placement area 1142.

[0049] Specifically, the earphone 2 includes an earphone head 21 and an earphone stem 22. When stored, the earphone stem 22 is located in the stem placement area 1142, and the earphone head 21 is located in the head placement area 1141. The side edge 1122 covers the stem placement area 1142, forming a deep hole structure that can accommodate the earphone stem 22 in conjunction with the middle frame 111. The opening of this deep hole is located on the side where the head placement area 1141 is located. When placing the earphone 2, the earphone stem 22 of the earphone 2 can be aligned with the head placement area 1141 and inserted, so that the earphone head 21 falls into the head placement area 1141. The side edge 1122 enhances the aesthetic appearance of the earphone charging case 1, improves its structural strength, and provides complete coverage of the earphone stem 22. This effectively improves the stability of the earphone 2 when stored and avoids the risk of the earphone 2 falling out of the earphone charging case 1.

[0050] In one embodiment, the two machine rod placement areas 1142 are respectively disposed on two opposite sides of the middle frame 111, and the two machine head placement areas 1141 are disposed on the same side of the middle frame 111.

[0051] Specifically, the earphone stem 22 has a long handle structure, while the earphone head 21 has a relatively short and rounded structure. The stem placement area 1142 is located on two opposite sides of the middle frame 111, and the two head placement areas 1141 are set on the same side of the middle frame 111. This fully utilizes the space around the middle frame 111, effectively preventing the earphone stems 22 from interfering with or overlapping each other when stored, and also providing a more spacious head placement area 1141 for the earphone head 21. This layout ensures the stability of the earphone 2 when stored and improves the utilization rate of space.

[0052] In addition, the two rod placement areas 1142 are respectively located on the two opposite sides of the middle frame 111, so that the earphone charging case 1 presents structural symmetry, which enhances the aesthetics of the product.

[0053] In one embodiment, reference is made to Figure 10 A charging port 1111 is provided on the side of the middle frame 111 away from the head placement area 1141.

[0054] Specifically, a battery 12 is also installed inside the earphone charging case 1. To charge the battery 12, a battery charging unit 14 is usually required. To allow the external charging cable to connect to the battery charging unit 14, a charging port 1111 needs to be reserved on the middle frame 111. Placing the charging port 1111 on the side away from the headphone placement area 1141 avoids interference between the charging cable and the earphones 2 when they are stored. This layout ensures that the space around the earphone charging case 1 is used efficiently, while also ensuring a smooth charging process.

[0055] In one embodiment, reference is made to Figure 7The inner and / or outer walls of the middle frame 111 are provided with magnetic components 16, which are adapted to attract and hold the earphones 2 placed in the earphone placement slot 114.

[0056] The magnetic attachment 16 securely holds the earphones 2 in the earphone slot 114, preventing them from slipping or moving during charging or carrying. This design ensures the stability of the earphones 2 within the charging case, avoiding poor charging contact or damage caused by earphone movement. The magnetic attachment 16 makes it easier for users to place or remove the earphones 2. Users simply need to gently bring the earphones 2 close to the magnetic attachment 16, and they will automatically be attracted into place. Similarly, when removing the earphones 2, users only need to apply slight force to detach them from the magnetic attachment 16. This design reduces user inconvenience during operation and improves ease of use.

[0057] In specific implementation, a magnetic suction element 16 can be provided on the inner wall of the middle frame 111, or a magnetic suction element 16 can be provided on the outer wall of the middle frame 111, or a magnetic suction element 16 can be provided on both the inner and outer walls of the middle frame 111.

[0058] In one embodiment, the earphone placement slot 114 includes a headphone placement area 1141 and a headphone rod placement area 1142, and the magnetic suction member 16 includes a headphone magnetic suction member 161 and a headphone rod magnetic suction member 162. The headphone magnetic suction member 161 is disposed on the middle frame 111 corresponding to the headphone placement area 1141, and the headphone rod magnetic suction member 162 is disposed on the middle frame 111 corresponding to the headphone rod placement area 1142.

[0059] The headphone placement area 1141 and the shaft placement area 1142 are respectively provided with headphone magnetic attachment 161 and shaft magnetic attachment 162, which can realize multi-point adsorption and fixation of the earphone 2 after storage. This helps to enhance the stability of the earphone 2 after storage and prevent the earphone 2 from falling off.

[0060] In one embodiment, reference is made to Figure 10 The inner side of the middle frame 111 is provided with an earphone charging unit 15. The earphone charging unit 15 includes charging pins. The middle frame 111 is provided with pin holes 1112 that communicate with the earphone placement slot 114. The charging pins are exposed in the earphone placement slot 114 through the pin holes 1112.

[0061] The headphone charging unit 15 is used to connect with the stored headphone 2 to charge the headphone 2. The user only needs to place the headphone 2 in the headphone placement slot 114, and the charging pins will automatically connect with the charging interface of the headphone 2 without the need for cumbersome plugging and unplugging operations.

[0062] In one embodiment, in the region of each of the headphone placement slots 114, the pin hole 1112 is disposed between the head magnetic member 161 and the shaft magnetic member 162.

[0063] In this structure, the pin hole 1112 is located between the head magnetic 161 and the stem magnetic 162, which means that the contact point between the earphone 2 and the charging pin is located between the head magnetic 161 and the stem magnetic 162. There is magnetic attraction on both sides of the contact point, and the magnetic attraction on both sides is balanced, which is more conducive to ensuring the stability of the contact between the earphone 2 and the charging pin, thereby ensuring stable charging.

[0064] In one embodiment, reference is made to Figure 8 The device mounting cavity 115 houses the battery 12, the main control board 13, and the battery charging unit 14.

[0065] Battery 12 serves as the primary energy source for the earphone charging case 1, providing the necessary power to the entire system. The main control board 13 is the core control component of the earphone charging case 1, responsible for managing and coordinating the operation of each component. It receives user commands, such as opening or closing the charging case and checking the battery 12's charge level, and accordingly controls the operating status of components such as the battery charging unit 14 and indicator lights. The main control board 13 also monitors the battery 12's charge level and charging status to ensure the safe use of the battery 12 and the smooth charging process. The battery charging unit 14 is responsible for charging the battery 12, ensuring that the battery 12 can continuously provide power to the earphone charging unit 15. It receives electrical energy by connecting to an external power source (such as a USB interface, TYPE-C interface, or power adapter) and converts it into voltage and current suitable for charging the battery 12.

[0066] In one embodiment, the battery 12 and the main control board 13 are disposed in the device mounting cavity 115 along a through direction parallel to the cavity of the middle frame 111.

[0067] The parallel arrangement of the battery 12 and the main control board 13 can make full use of the longitudinal space in the device mounting cavity 115 and avoid unnecessary space waste. This layout makes the internal structure of the earphone charging case 1 more compact, which is conducive to reducing the overall size and weight and improving portability.

[0068] In one embodiment, combined with Figure 12 The battery charging unit 14 includes a charging control board 141 and a charging connector 142. A charging socket 1111 corresponding to the charging connector 142 is provided on one side of the middle frame 111. An avoidance groove 121 is provided on the side of the battery 12 near the charging socket 1111. The charging control board 141 is at least partially embedded in the avoidance groove 121.

[0069] The charging control board 141 is responsible for receiving electrical energy from an external power source and regulating and managing it to ensure that the battery 12 can be charged safely and efficiently; the charging connector 142 is responsible for physically connecting to the external power source and transmitting electrical energy to the charging control board 141.

[0070] A clearance groove 121 is provided on the side of the battery near the charging port 1111. The presence of the clearance groove 121 allows the charging control board 141 to be at least partially embedded inside the battery 12, thereby saving space and making the entire headphone charging case 1 more compact.

[0071] In one embodiment, the first panel 112 and the second panel 113 have the same shape and size.

[0072] In this way, the first panel 112 and the second panel 113 can be produced simultaneously using the same mold, without the need to design different molds for different panels. This not only saves on mold development and maintenance costs, but also improves production. Since the first panel 112 and the second panel 113 are the same, large-scale mass production can be achieved, further reducing production costs and increasing output.

[0073] During assembly, since the first panel 112 and the second panel 113 are identical, workers do not need to distinguish them, which simplifies the assembly process and reduces the possibility of assembly errors.

[0074] In addition, the identical shape and size make the first panel 112 and the second panel 113 visually form a unified whole, enhancing the overall aesthetics of the device.

[0075] In one embodiment, the first panel 112 and the second panel 113 are respectively provided with positioning protrusions 1123, and the middle frame 111 is correspondingly provided with positioning grooves 1113, and the positioning protrusions 1123 are engaged in the positioning grooves 1113.

[0076] The design of the positioning protrusion 1123 and the positioning groove 1113 enables the panel to quickly and accurately find the correct position during assembly, avoiding misalignment and deviation during the assembly process. After the positioning protrusion 1123 is engaged with the positioning groove 1113, a firm connection is formed, ensuring that the panel will not loosen or fall off due to external force, which helps to extend the service life of the equipment.

[0077] Optionally, the first panel 112 and the middle frame 111, and the second panel 113 and the middle frame 111 are respectively bonded and fixed with waterproof adhesive.

[0078] On the other hand, refer to Figures 1-4 A wireless earphone assembly is provided, comprising:

[0079] Two earphones 2;

[0080] The earphones 2 can be placed in the earphone placement slot 114 of the earphone charging case 1.

[0081] Based on the earphone charging case 1 of this embodiment, the wireless earphone assembly of this embodiment has the advantages of large battery capacity and small overall size.
