[0032] 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.
[0033] The present invention provides an earphone charging compartment 1. Figures 1 to 3 As shown, the earphone charging case 1 includes a base 11, a flip cover 12, a main control circuit board 13, a flexible circuit board 14, and a display screen 15. The main control circuit board 13 is mounted in the base 11, and the display screen 15 is mounted on the flip cover 12. The side of the flip cover 12 is provided with a shaft mounting boss 121 protruding toward the inside of the flip cover 12. The shaft mounting boss 121 is mounted with a shaft 19. The flip cover 12 is rotatably connected to the base 11 via the shaft 19, so that the flip cover 12 can be closed and opened on the base 11.
[0034] The flexible circuit board 14 is installed in the base 11 and the flip cover 12. The flexible circuit board 14 passes through the rotating shaft mounting boss 121 and is electrically connected to the main control circuit board 13 and the display screen 15 respectively; the flexible circuit board 14 is bent corresponding to the rotating shaft mounting boss 121 to form a bending avoidance groove 141, and the rotating shaft mounting boss 121 is located in the bending avoidance groove 141.
[0035] The hinge mounting boss 121 protruding inwardly of the earphone charging case 1 of the present invention can enhance the structural strength of the rotating connection of the flip cover 12, and can make the connection of the flip cover 12 more stable. At the same time, a flexible circuit board 14 is used to realize the electrical connection between the display screen 15 arranged on the flip cover 12 and the main control circuit board 13 arranged in the base 11. The flexible circuit board 14 is bent at the position corresponding to the hinge mounting boss 121 to form a bending avoidance groove 141, so that when the flexible circuit board 14 passes through the position of the hinge mounting boss 121, it can avoid the hinge mounting boss 121 through the bending avoidance groove 141. When the flip cover 12 rotates, the interference between the hinge mounting boss 121 and the flexible circuit board 14 is reduced, the flexible circuit board 14 is not easily damaged, and the electrical connection of the flexible circuit board 14 is stable.
[0036] The display screen 15 can be used to display the power level and charging status of the earphone charging compartment 1. Of course, the user can also interactively control the earphones through the screen, adjust the sound effect settings of the earphones, switch songs, etc. The display screen 15 can be further protected by a transparent protective cover 151. The main control circuit board 13 is the control circuit board of the earphone charging compartment 1, which is responsible for the charging and discharging of the earphone charging compartment 1, the control of the display screen 15, etc. The flexible circuit board 14 (Flexible Printed Circuit, FPC) is a printed circuit board with high reliability and flexibility. Compared with traditional rigid PCBs, FPC can be bent and curled, and is suitable for applications in scenarios where space is limited or flexible connections are required. The conductive material (usually copper) therein can also be used to make a conductive circuit and use it as a wire. Furthermore, the top of the base 11 is arranged in an inclined plane from top to bottom, and the flip cover 12 is arranged accordingly.
[0037] Alternatively, as Figures 4 to 6 As shown, the earphone charging case 1 also includes an elastic member 16, which is installed at the rotational connection between the flip cover 12 and the base 11, and is respectively connected to the flip cover 12 and the base 11 to provide an elastic positioning force for closing and opening the flip cover 12. The flexible circuit board 14 is bent corresponding to the elastic member 16 to form an avoidance position 142, and the avoidance position 142 avoids the elastic member 16 and / or the installation position of the elastic member 16. The avoidance position 142 is bent corresponding to the elastic member 16 on the flexible circuit board 14, which can effectively avoid the elastic member 16 and its installation position. This design can reduce the interference between the elastic member 16 and the flexible circuit board 14 when the flip cover 12 rotates, and reduce the risk of damage to the flexible circuit board 14 due to friction and wear. Furthermore, the curved avoidance groove 141 formed on the flexible circuit board 14 at the shaft mounting boss 121, combined with the avoidance position 142 on the elastic member 16, works together to make the connection of the flexible circuit board 14 more stable during the rotation of the flip cover 12, ensuring that the electrical connection between the display screen 15 and the main control circuit board 13 is not easily affected during the rotation of the flip cover 12, thereby improving the electrical performance and reliability of the entire earphone charging.
[0038] Specifically, further combining Figure 8 As shown, the flexible circuit board 14 includes a first connecting section 143, a second connecting section 144, a first curved section 145, and a first bent section 146. The first connecting section 143 is electrically connected to the display screen 15, and the second connecting section 144 is electrically connected to the main control circuit board 13. The first bent section 145 is connected to the first connecting section 143 and is arranged transversely relative to the first connecting section 143. The first bent section 146 is L-shaped and connects to the first curved section 145 and the second connecting section 144, respectively. A bending avoidance groove 141 is formed in the first curved section 145, and the first bent section 146 and the first curved section 145 together form an avoidance position 142. The first connecting section 143 and the second connecting section 144 are electrically connected to the display screen 15 and the main control circuit board 13, respectively, ensuring electrical connection between the display screen 15 and the main circuit board 13. The bending avoidance groove 141 is provided on the first bending section 145 . The first bending section 145 and the first bending section 146 together form an avoidance position 142 , so that the flexible circuit board 14 can effectively avoid the shaft mounting boss 121 and the elastic member 16 when the flip cover 12 rotates, thereby reducing mechanical interference and protecting the flexible circuit board 14 from damage.
[0039] Specifically, if Figure 5 and Figure 6As shown, the headphone charging case 1 also includes a support gasket 17, which is positioned within the flip cover 12 and attached to the portion of the flexible circuit board 14 where the bend avoidance groove 141 is located. Positioned on the inside of the flip cover 12 and attached to the bend avoidance groove 141 of the flexible circuit board 14, the support gasket 17 provides additional physical support for the flexible circuit board 14, helping to protect it from impact or pressure during rotation, thereby reducing wear and damage to the flexible circuit board 14. When the flip cover 12 rotates, the flexible circuit board 14 is susceptible to mechanical stress, particularly in the bend avoidance groove 141 area near the hinge mounting boss 121. The support gasket 17 distributes this stress, reducing direct forces acting on the flexible circuit board 14, thereby improving its durability. It also provides shielding for the flexible circuit board 14. The support gasket 17 can be a silicone gasket, rubber gasket, or foam gasket, among others. The support gasket 17 can be glued to the inside of the flip cover 12 or to the flexible circuit board 14.
[0040] like Figure 7 As shown, a first mounting seat 122 is provided on the side of the rotating shaft mounting boss 121 near the base 11. A second mounting seat 111a is provided within the base 11. The elastic member 16 is a torsion spring, mounted on the first mounting seat 122 and the second mounting seat 111a, respectively. A clearance position 142 clears the torsion spring and the first mounting seat 122. Providing the first mounting seat 122 within the base 11 and the second mounting seat 111a within the flip cover 12 provides stable support and positioning for the torsion spring. The elastic properties of the torsion spring enable it to provide appropriate positioning force, ensuring that the flip cover 12 is precisely positioned in the desired position when opened or closed. The clearance position 142 allows the flexible printed circuit board 14 to clear the torsion spring and the first mounting seat 122, reducing potential interference or damage to the flexible printed circuit board 14 caused by the torsion spring and the first mounting seat 122 when the flip cover 12 rotates. Specifically, the first mounting seat 122 is provided with a mounting hole 122a, into which one end of the torsion spring is mounted.
[0041] Furthermore, if Figure 9As shown, the base 11 is provided with an earphone receiving seat 111, which is provided with two side-by-side earphone receiving cavities 111b. A second mounting seat 111a is provided on the outer wall between the two earphone receiving cavities 111b. The second mounting seat 111a is provided on the outer wall between the two earphone receiving cavities 111b to provide support and fixation for the second mounting seat 111a. The second mounting seat 111a also helps to improve the structural stability of the two earphone receiving cavities 111b. Furthermore, the location of the second mounting seat 111a between the two earphone receiving cavities 111b facilitates the installation of the torsion spring. Furthermore, two opposing rotating shaft mounting seats 111c are provided near the edge of the earphone receiving seat 111 near the rotating shaft 19. The ends of the rotating shaft 19 are rotatably mounted in the two rotating shaft mounting seats 111c. Specifically, the main control circuit board 13 is mounted on the bottom of the earphone receiving seat 111. A battery 18 electrically connected to the main control circuit board 13 is also provided between the earphone receiving seat 111 and the main control circuit board 13.
[0042] Specifically, the second mounting base 111a includes two vertically opposed limiting edges 111a1, with one end of the torsion spring mounted between the two limiting edges 111a1. The provision of two opposing limiting edges 111a1 provides a stable mounting position and precise positioning for the torsion spring, ensuring that the torsion spring is less likely to shift after installation and maintains proper working condition. This simplifies the assembly process of the torsion spring, requiring only one end of the torsion spring to be secured between the limiting edges 111a1 and the other end to be secured in the corresponding position. Furthermore, when the flip cover 12 rotates, the support pad 17 is pressed against the headphone receiving base 111.
[0043] like Figures 1 to 9 As shown, the present invention also discloses an earphone kit, including a Bluetooth headset 2 and the above-mentioned earphone charging compartment 1. The Bluetooth headset 2 can be stored in the base 11 and charged. Since the earphone kit has the above-mentioned earphone charging compartment 1, it also has the technical effects of the above-mentioned earphone charging compartment 1, which will not be repeated here.
[0044] 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.
