[0051] Example
[0052] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this embodiment provides a wireless charging box for headphones, including a shell 10, a heat-conducting frame 11, a charging compartment 12, a weighted base 14 and a charging component 15.
[0053] Specifically, the heat-conducting frame 11 is arranged in the shell 10, and two receiving ports 101 are symmetrically arranged on the top of the shell 10. The number of charging compartments 12 is two corresponding to the number of receiving ports 101, and the number of charging coils 13 is also two corresponding to the number of receiving ports 101. Both charging compartments 12 are arranged on the heat-conducting frame 11, and the compartment opening of one charging compartment 12 is arranged on one receiving port 101, and the compartment opening of the other charging compartment 12 is arranged on the other receiving port 101. The charging coil 13 is arranged between the charging compartment 12 and the heat-conducting frame 11, and is electrically connected to the charging assembly 15 arranged on the heat-conducting frame 11. The two charging compartments 12 can cooperate to accommodate a pair of wireless headphones for charging. The specific charging principle is common knowledge in the art, and this application will not elaborate on it here.
[0054] In addition, the counterweight base 14 is arranged at the bottom of the shell 10, and the top of the counterweight base 14 passes through the shell 10 and extends into the shell 10. The counterweight base 14 can increase the weight of the bottom of the wireless charging box, so that the wireless charging box can be stably placed upright when connected for charging and is not easy to tip over, thereby avoiding the bending of the charging cable to affect the charging efficiency and the service life of the charging cable.
[0055] Furthermore, since the charging coil 13 generates heat when it is working, in order to dissipate the heat faster, the heat-conducting frame 11 and the weight base 14 can be made of metal materials with good thermal conductivity. An optional material of the heat-conducting frame 11 and the weight base 14 is aluminum alloy. Specifically, the heat generated by the charging coil 13 when it is working can be dissipated by conduction from the heat-conducting frame 11, so that the heat quickly flows into the entire housing 10 with the air, and is quickly dissipated to the outside of the housing 10 through the weight base 14, thereby quickly reducing the temperature inside the housing 10, which will not affect the charging time, and at the same time solve the problem of heating during charging of the wireless headset box, improve the charging efficiency, so that users have a better user experience and have good practicality.
[0056] like Figure 4 and Figure 5As shown, in this embodiment, a thermally conductive silicone gasket 131 is provided at the bottom of the charging coil 13. The thermally conductive silicone gasket 131 has good thermal conductivity. By providing the thermally conductive silicone gasket 131 at the bottom of the charging coil 13, the heat dissipation speed can be improved. The thermally conductive silicone gasket 131 also has a certain compression performance, which can play a good shockproof effect on the charging coil 13, and prevent the charging coil 13 from shifting due to shaking caused by the user during use.
[0057] like Figure 4 and Figure 5 As shown, in this embodiment, the charging component 15 includes a circuit board 151, a battery (not shown in the figure) electrically connected to the circuit board 151, and a charging interface 152 electrically connected to the circuit board 151. The charging interface 152 is arranged on the shell 10, and the wireless charging box can be connected and charged through the charging interface 152.
[0058] In addition, the top of the circuit board 151 is provided with a fixing piece 1511 for locking the circuit board 151 on the heat-conducting frame 11. The fixing piece 1511 can be a screw or a bolt, or can be glue or a welding rod. The circuit board 151 is fixed by gluing or welding to ensure the stability of the installation of the circuit board 151 and avoid the shaking of the user during use, which may cause the circuit board 151 to shift and collide. The top of the counterweight base 14 is provided with a slot 141 for avoiding the circuit board 151. The top of the circuit board 151 is installed on the heat-conducting frame 11, and the bottom can be inserted into the slot 141 to reduce the occupied space, thereby ensuring the overall miniaturization of the wireless earphone box.

[0064] like Figure 4 and Figure 5 As shown, the present embodiment also includes a support column 16, and two support columns 16 are symmetrically arranged. One support column 16 is arranged on the top of the heat-conducting frame 11 and connected to the top of the side frame 104, and the other support column 16 is also arranged on the top of the heat-conducting frame 11 and connected to the top of the side frame 104. The two symmetrically arranged support columns 16 form a good support for the side frame 104 to prevent the side frame 104 from being deformed by force during use.
[0065] like Figure 4 and Figure 5As shown, in this embodiment, a support portion 121 for supporting the charging compartment 12 is provided between the charging compartment 12 and the heat-conducting frame 11. The support portion 121 and the charging compartment 12 are integrally formed and can be fixed by screws to the support portion 121 and the heat-conducting frame 11, so that the charging compartment 12 is firmly installed on the heat-conducting frame 11, and the position of the charging compartment 12 is raised by the support portion 121, so that there is an installation space between the charging compartment 12 and the heat-conducting frame 11 for installing the charging coil 13 and the heat-conducting silicone gasket 131. In addition, the edge of the accommodating opening 101 is protrudingly provided with a clamping portion 1011 for clamping the top of the charging compartment 12, and the clamping portion 1011 can further play a role in fixing and limiting the charging compartment 12 to ensure the stability of the charging compartment 12.
