Detailed Implementation Methods

[0031] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0032] Please see Figures 1 to 11 This embodiment provides a TWS earphone case with replaceable batteries, including an upper shell 1. The upper shell 1 is connected to a housing 2 for placing earphones. A lower shell 3 is connected below the housing 2. The lower shell 3 has an installation position 5 for placing batteries 4. The lower shell 3 is detachably connected to a battery cover 6 for closing the installation position 5. A locking structure 7 is provided between the housing 2 and the battery cover 6 to fix the two together.

[0033] In this embodiment, the upper shell 1 of the earphone case is hinged to the receiving compartment 2, and the lower shell 3 is fixed below the receiving compartment 2 by a snap-fit ​​or threaded connection. The mounting position 5 of the lower shell 3 is used to place the battery 4, and its shape is adapted to the battery 4 to ensure that the battery 4 is stable after installation. The lower shell 3 is detachably connected to the battery cover 6 by a locking structure 7. Since the locking mechanism 7 is located inside the earphone case, this connection method ensures both the firmness of the connection and does not affect the appearance of the case.

[0034] Because the TWS earphone case of this embodiment has a replaceable battery, when the battery capacity of the earphone case is insufficient or the battery is damaged, the user can easily open the battery cover 6 to replace the new battery instead of replacing the entire earphone case. This significantly improves the ease of use and lifespan of the TWS earphone case, overcomes the shortcomings of traditional non-replaceable battery earphone cases with limited battery life, and provides users with longer-lasting power guarantee for using earphones in various scenarios.

[0035] The locking structure 7 between the housing 2 and the battery cover 6 effectively enhances the stability of their connection, preventing the battery cover 6 from being accidentally opened during daily use, avoiding the battery 4 from becoming loose or shifting, ensuring that the headphone case can work normally, and also improving the overall stability and reliability of the headphone case structure, reducing the risk of damage to internal components due to the loose battery cover, and extending the service life of the headphone case. Moreover, since the locking mechanism 7 is located inside the charging case, this connection method not only ensures the firmness of the connection, but also does not affect the appearance of the case, keeping the headphone case in a simple and beautiful appearance.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the locking structure 7 includes a connecting part 71 located at the bottom of the receiving compartment 2 and detachably connected to the battery cover 6. The connecting part 71 has a mounting through hole 72 penetrating the receiving compartment 2, so that fasteners can pass through the mounting through hole 72 from the top of the receiving compartment 2 and be fixed to the battery cover 6.

[0037] In this embodiment, the connecting part 71 in the locking structure 7 is located at the bottom of the receiving compartment 2 and is detachably connected to the battery cover 6. The connecting part 71 has a mounting through hole 72 that penetrates the receiving compartment 2. When it is necessary to fix the battery cover 6, a fastener such as a screw is used to pass through the mounting through hole 72 from the top of the receiving compartment 2 and then to securely connect with the battery cover 6. This design makes the connection between the battery cover 6 and the receiving compartment 2 stable and reliable. Through the cooperation of the connecting part 71 of the locking structure 7, the mounting through hole 72, and the fastener, the battery cover 6 is tightly fixed to the receiving compartment 2. In daily use, whether the headphone case is placed in a backpack and shakes with the movement of the body or is subjected to a slight external impact, the battery cover 6 can remain stably closed, effectively preventing the battery 4 from being accidentally exposed or falling off, ensuring the normal use of the headphone case and the safety of the battery. For example, during daily commutes, the user puts the headphone case in a pocket or handbag, and even after frequent movement and collisions, the battery cover 6 will not come loose. When maintenance or replacement of the battery cover 6 or the housing 2 is required, the battery cover 6 and the housing 2 can be easily separated simply by removing the fasteners from the mounting through-hole 72. This operation is simple and convenient. This improves the efficiency of the assembly process during production and facilitates quick disassembly and repair by after-sales service personnel or users themselves when dealing with related issues, reducing maintenance and time costs and improving the maintainability of the entire TWS earphone case.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the mounting position 5 includes a battery slot 51, and an assembly slot 52 matching the shape of the battery cover 6 is provided above the battery slot 51.

[0039] In this embodiment, the mounting position 5 of the lower shell 3 includes a battery slot 51, in which the battery 4 can be precisely placed. The size of the battery slot 51 is closely matched with that of the battery 4, effectively preventing the battery 4 from shaking or shifting within it. Above the battery slot 51, there is a mounting groove 52 that matches the shape of the battery cover 6. When the battery cover 6 is installed, it can be perfectly fitted into the mounting groove 52.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, a first assembly hole 521 communicating with the interior of the lower shell 3 is provided on one side of the assembly groove 52, and a locking part 61 is provided on one side of the battery cover 6 that can extend into the first assembly hole 521 and be fixed to the mounting through hole 72 by fasteners.

[0041] In this embodiment, one side of the mounting groove 52 is provided with a first mounting hole 521 communicating with the interior of the lower shell 3, and the battery cover 6 has a locking part 61 that can extend into the first mounting hole 521 on the corresponding side. The connecting part 71 of the locking structure 7 forms a detachable connection with the battery cover 6 at the bottom of the receiving compartment 2. The mounting through hole 72 provided therein allows the fastener to pass through from above the receiving compartment 2 and be fixed to the locking part 61 extending into the first mounting hole 521, thereby tightly locking the battery cover 6 onto the mounting groove 52. Through the synergistic effect of the first mounting hole 521, the locking part 61, the mounting through hole 72, and the fastener, an extremely stable locking mechanism for the battery cover 6 is constructed. In daily use, whether the headphone case is frequently opened and closed, or subjected to various bumps and shakes during carrying, the battery cover 6 can always remain firmly closed, effectively preventing the battery 4 from accidentally falling out and ensuring the safety and stability of the headphone case and the internal battery. Furthermore, since the locking components are all located within the internal structure, the connection traces are almost invisible from the outside, maintaining the overall simplicity and aesthetics of the earphone case and enhancing the product's appearance and quality.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the locking part 61 is provided with a first insertion part 611 on each side, which can be connected to the assembly groove 52, and the assembly groove 52 is provided with an insertion hole 522 corresponding to the first insertion part 611.

[0043] When installing the battery cover 6, first insert the locking part 61 into the first mounting hole 521, and at the same time insert the first insertion part 611 into the insertion hole 522. Then, use fasteners to pass through the mounting through hole 72 to complete the final fixation.

[0044] In this embodiment, the first insertion part 611 is preferably a detachable snap-fit. The cooperation between the first insertion part 611 and the insertion hole 522 provides additional connection stability between the battery cover 6 and the mounting groove 52. In daily use, even when subjected to relatively severe external impacts or frequent opening and closing operations, this multi-connection method can effectively distribute the force, preventing the battery cover 6 from becoming loose, shifting, or even falling off, ensuring that the battery 4 is always in a safe and stable closed environment, guaranteeing the normal use of the headphone case and the safety of the battery. For example, when using the headphone case in sports scenarios, such as during running or fitness activities, the multi-connected battery cover 6 can still remain tightly closed despite the shaking and collisions.

[0045] Furthermore, the design of the first insertion part 611 and the insertion hole 522 not only enhances the connection strength but also provides precise positioning. When installing the battery cover 6, the user can quickly and accurately place the battery cover 6 in the correct position based on the correspondence between the first insertion part 611 and the insertion hole 522, and then perform the fixing operation of the locking part 61 and the mounting through hole 72, which greatly improves the convenience and efficiency of assembly.

[0046] Furthermore, as a preferred embodiment of this solution and not a limitation, one end of the assembly groove 52 is provided with a positioning groove 523, and the battery cover 6 is provided with a second insertion part 62 corresponding to the positioning groove 523 on the side facing the mounting position 5.

[0047] In this embodiment, the cooperation between the positioning groove 523 and the second insertion part 62 further improves the installation efficiency of the battery cover 6 and the connection stability between it and the mounting position 5.

[0048] Furthermore, as a preferred embodiment of this solution and not a limitation, a groove 53 is provided at the upper edge of one side of the mounting position 5 to facilitate battery removal. When replacing the battery, the user does not need to use complicated tools to remove it. Simply insert a finger into the edge of the groove 53 to form surface contact with the battery 4, and it can be easily pried out.

[0049] Furthermore, as a preferred embodiment of this solution and not a limitation, the receiving compartment 2 is provided with a sealing element 21 for concealing the mounting through hole 72. The sealing element 21 is preferably a silicone plug that is easy to remove, which not only serves an aesthetic purpose but also provides a certain degree of protection for the mounting through hole 72 and related internal connection structures. It can prevent dust, moisture, and other impurities from entering the internal structure of the headphone case through the mounting through hole 72, reducing problems such as short circuits and corrosion caused by impurities, thereby extending the service life of the internal components of the headphone case and improving the reliability and stability of the product.

[0050] Furthermore, as a preferred embodiment of this solution and not a limitation, the housing 2 includes two symmetrically arranged headphone slots 22, with the mounting through hole 72 provided between the two headphone slots 22. This achieves efficient utilization of the internal space of the housing 2.

[0051] Furthermore, as a preferred embodiment of this solution and not a limitation, the bottom of the mounting position 5 is provided with a connector 54 for electrical connection with the battery. Since the connector 54 is located at the bottom of the mounting position 5, its position is fixed and it fits well with the battery 4. This eliminates the need for complex wiring operations when replacing the battery 4; the user simply places the new battery in the battery slot 51 in the correct orientation, and the electrical connection is automatically completed. This convenient design greatly improves the efficiency of battery replacement, reduces the difficulty of user operation, and allows users to quickly replace the battery when it is low on power, rapidly restoring the earphone's usability and enhancing the overall practicality and user-friendliness of the product.

[0052] Furthermore, as a preferred embodiment of this solution and not a limitation, the battery cover 6 is provided with a structural reinforcing rib 63 on the end face facing the mounting position 5, which can abut against the battery.

[0053] In this embodiment, the contact between the structural reinforcing rib 63 and the battery 4 effectively enhances the stability of the battery 4 within the battery slot 51. This prevents the battery 4 from shifting or loosening significantly due to external forces, avoiding problems such as electrical connection interruptions. It ensures that the headphones can receive a continuous and stable power supply, improves the reliability of the product, and reduces the probability of malfunctions caused by battery displacement.

[0054] Meanwhile, by limiting the excessive movement of the battery 4, the structural reinforcing rib 63 can also prevent the battery 4 from unnecessary collisions and friction with the inner wall of the battery compartment 51 or other internal structures, thereby protecting the outer shell of the battery 4 and internal components such as the battery cells from damage. It also reduces the potential risk of damage to other related components in the mounting position 5, such as the connector 54, which helps to extend the service life of the battery 4 and the entire headphone case, reduce the user's operating costs and maintenance frequency, and improve the product's durability and cost-effectiveness.

[0055] Furthermore, the presence of the structural reinforcing rib 63 creates a tighter and more stable overall structure between the battery cover 6, the battery 4, and the mounting position 5. This integrity not only protects the battery 4 but also improves the overall mechanical properties of the headphone case, allowing it to better distribute stress when subjected to various external forces. This further enhances the structural strength of the headphone case, ensuring the product's normal operation in complex environments and improving user satisfaction.
