[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.
[0028] The present invention provides an earphone charging case. Figures 1 to 4 As shown, the earphone charging compartment includes a bottom shell 1, a flip cover 2, a main control circuit board 3, a first flexible circuit board 4, a display screen 5, an earphone storage seat 6 and a charging connector 7; the flip cover 2 is rotatably connected to the bottom shell 1 so that the flip cover 2 can be closed and opened on the bottom shell 1; the display screen 5 is arranged on the flip cover 2, and the main control circuit board 3, the earphone storage seat 6 and the first flexible circuit board 4 are arranged in the bottom shell 1, and the main circuit board 3 is located at the bottom of the earphone storage seat 6; the first flexible circuit board 4 is electrically connected to the main circuit board 3, and is led out from the back side of the earphone storage seat 6 to the flip cover 2 and electrically connected to the display screen 5; the charging connector 7 is electrically connected and installed on the main circuit board 3 and docked with the opening on the back side of the bottom shell 1.
[0029] The portion of the first flexible circuit board 4 inside the bottom case 1 includes a bending avoidance section 41 electrically connected to the main control circuit board 3. The bending avoidance section 41 is located next to the charging connector 7 and is bent away from the charging connector 7 to avoid the charging connector 7.
[0030] The headphone charging compartment's main control circuit board 3 and display screen 5 are connected via a first flexible circuit board 4. The portion of the first flexible circuit board 4 within the bottom housing 1 is configured as a curved escape section 41, which bends away from the charging connector 7, thereby avoiding the charging connector 7. This not only takes advantage of the flexible circuit board's inherent sheet-like regularity and integration compared to conventional wires, avoiding the difficulties of layout and assembly caused by cluttered layout and the potential for interference with the charging port, but also avoids interference between the charging connector 7 and the curved escape section 41, making it less likely to generate electromagnetic interference that could affect the display on the display 5.
[0031] Specifically, the first flexible circuit board 4 is a flexible printed circuit board (FPC). The display screen 5 is used to display the usage status of the headphone charging compartment, such as the power level and charging status of the headphone charging compartment. The main control circuit board 3 controls the charging and discharging of the headphone charging compartment, the display screen 5, etc., which will not be described in detail here. The display screen 5 is installed on the front face of the flip cover 2. The first flexible circuit board 4 is led out from the rotation connection between the flip cover 2 and the bottom shell 1 to the flip cover 2 and connected to the display screen 5. Figure 3 As shown, the flip cover 2 includes an inner cover 21 and an outer cover 22 , and the first flexible circuit board 4 is connected to the display screen 5 between the inner cover 21 and the outer cover 22 .
[0032] Furthermore, a first support pad 8 is installed at the location of the headphone receiving seat 6 corresponding to the bend avoidance section 41, and the bend avoidance section 41 is supported on the first support pad 8. In this embodiment, the first support pad 8 is provided at the location of the headphone receiving seat 6 corresponding to the bend avoidance section 41 to support the bend avoidance section 41. The first support pad 8 can provide support, cushioning protection, and positioning for the bend avoidance section 41, thereby improving the service life and stability of the first flexible circuit board 4. Specifically, the first support pad 8 can be made of foam, etc.
[0033] Further integration Figure 5As shown, the headphone receiving seat 6 has a support plate 61 at a position corresponding to the bend avoidance section 41, and the first support pad 8 is mounted on the support plate 61. In this solution, the headphone receiving seat 6 has a support plate 61 at a position corresponding to the bend avoidance section 41, and the first support pad 8 is mounted on the support plate 61. The support plate 61 provides a flat mounting surface for the first support pad 8, improving the installation convenience and stability of the first support pad 8. The first support pad 8 can be bonded to the support plate 61 with glue. The first support pad 8 is in the shape of a rectangular parallelepiped, and the shape of the support plate 61 corresponds to the shape of the first support pad 8.
[0034] The portion of the first flexible circuit board 4 within the bottom case 1 includes a concave curved section 42 connected to the bend avoidance section 41. This section bends toward the headphone cradle 6. This section provides a pull margin when the flip cover 2 rotates, preventing damage to the first flexible circuit board 4 due to insufficient length margin when the flip cover 2 is opened. Furthermore, the concave curved section 42 improves the electrical connection stability of the display screen 5. This extends the folding life of the first flexible circuit board 4 when the flip cover 2 is repeatedly opened and closed. Currently, this lifespan can exceed 10,000 folds, compared to only approximately 2,000 to 5,000 folds for other flexible circuit board structures.
[0035] Specifically, the inwardly curved section 42 abuts against the headphone receiving seat 6. More specifically, the headphone receiving seat 6 is provided with two opposing abutting ribs 62 corresponding to the inwardly curved section 42 and extending toward the main control circuit board 3 and the flip cover 2. The inwardly curved section 42 abuts against the two abutting ribs 62. The abutting ribs 62 provide support and positioning for the inwardly curved section 42, ensuring that the inwardly curved section 42 is positioned in the predetermined position.
[0036] Furthermore, the two sides of the concave curved section 42 extend outward to form abutting portions 421, and the two abutting portions 421 respectively abut against the two abutting ribs 62. The provision of the abutting portions 421 can increase the lateral area of the concave curved section 42, ensuring that the concave curved section 42 can stably abut against the two abutting ribs 62. Specifically, the headphone receiving seat 6 has two headphone receiving grooves 64, one of which is provided on the wall surface of one headphone receiving groove 64 within the bottom shell 1, and the other is provided on the wall surface of the other headphone receiving groove 64 within the bottom shell 1.
[0037] Furthermore, the headphone charging compartment also includes a battery 9, which is mounted on the bottom of the main control circuit board 3 and electrically connected to the main control circuit board 3. This arrangement of the battery 9 on the bottom of the main control circuit board 3 creates a compact overall structure with high space utilization. The battery 9 provides power to the display 5 and simultaneously charges the Bluetooth headset via the main control circuit board 3. The battery 9 itself is charged via the aforementioned charging connector 7.
[0038] Further integration Figure 6 As shown, the earphone charging compartment also includes a battery mount 10, which is mounted on the bottom of the main control circuit board 3. The battery mount 10 has a mounting cavity 101 that opens toward the bottom of the bottom shell 1. The battery 9 is mounted in the mounting cavity 101. The mounting cavity 101 has first openings 102 at both ends. The battery mount 10 can improve the installation convenience and stability of the battery 9 while providing protection for the battery 9. The mounting cavity 101 that opens toward the bottom of the bottom shell 1 facilitates the assembly of the battery 9 into the mounting cavity 101. The battery 9 can be further fixed in the mounting cavity 101 by glue.
[0039] like Figure 4 and Figure 5 As shown, a plurality of studs 63 are provided at the bottom of the earphone receiving seat 6 , and the main control circuit board 3 and the battery mounting seat 10 are fixedly mounted on the corresponding studs 63 by screws.
[0040] The end of the bending avoidance section 41 is provided with a connecting plug 43, and the bending avoidance section 41 is electrically connected to the main control circuit board 3 through the connecting plug 43. A accommodating groove 103 is provided on the side of the battery mounting base 10 facing the main control circuit board 3, corresponding to the connecting plug 43. A second support pad 20 is provided in the accommodating groove 103, and the connecting plug 43 is supported on the second support pad 20. The second support pad 20 can support and protect the connecting plug 43, and can also improve the connection stability between the connecting plug 43 and the main control circuit board 3. The setting of the accommodating groove 103 can play the role of limiting the installation of the second support pad 20, while avoiding the installation space to facilitate the connection of the connecting plug 43. In addition, it can also reduce the gap between the battery mounting base 10 and the main control circuit board 3, making the structure more compact. The second support pad 20 can be a sponge, which can be bonded to the accommodating groove 103 by glue.
[0041] The present invention also discloses an earphone kit, comprising a Bluetooth headset and the aforementioned earphone charging compartment. The Bluetooth headset can be stored and charged in the earphone storage seat 6. This earphone kit has the same structure and benefits as the earphone charging compartment in the aforementioned embodiment. The structure and benefits of the earphone charging compartment have been described in detail in the aforementioned embodiment and will not be repeated here.
[0042] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Those skilled in the art may modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
