[0031] See Figures 1-6 A headphone charging structure includes a charging case 10 and headphone 20. The charging case 10 has a cavity 110, and the headphone 20 can be placed inside the cavity 110.

[0032] The charging module 40 includes at least an earphone charging motherboard 420 disposed on the earphone 20, and two charging pads 410 disposed on the outer wall of the earphone 20, the charging pads 410 being electrically connected to the earphone charging motherboard 420.

[0033] The conductive module 30 includes at least a charging case main board 310 disposed on the earphone 20; two bonding spring elements 320 are disposed in the cavity 110, and the bonding spring elements 320 are electrically connected to the charging case main board 310.

[0034] When the earphone 20 is placed in the cavity 110, the bonding spring element 320 is bonded to the charging piece 410 for conduction.

[0035] In this invention, the sheet-type contact conductivity effectively improves the waterproof performance of the earphone portion, achieving structural waterproofing. The adhesive contact conductivity prevents sweat from seeping into the earphone's interior, protecting the internal modules from corrosion by sweat immersion, thus allowing for normal charging.

[0036] The charging case features a highly elastic contact element that offers superior reliability and durability compared to traditional spring-loaded earbuds. Furthermore, the contact element has a larger surface area and differs significantly from traditional spring-loaded earbuds in structure and principle, possessing its own elasticity and eliminating the need for a spring. Its larger surface area also makes it more corrosion-resistant, easier to clean, and allows for better contact with the earbuds' charging contacts, ensuring effective charging.

[0037] like Figure 4 and Figure 5 As shown, the headphone charging motherboard 420 is provided with a connecting element 430; the charging pad 410 includes a bonding piece 411 disposed on the outer wall of the headphone 20, the bonding piece 411 is provided with a connecting pin 412, and the connecting pin 412 is detachably connected to the connecting element 430. The plug-in assembly not only facilitates assembly but also improves assembly efficiency, optimizes the assembly process, and thus improves production efficiency.

[0038] like Figure 5 As shown, the outer wall of the earphone 20 is provided with a mounting groove 210, and the mounting groove 210 is provided with a through hole 220 communicating with the interior of the earphone 20; the fitting piece 411 is disposed in the mounting groove 210, and the connecting pin 412 passes through the through hole 220 and is detachably connected to the connecting element 430. The mounting groove 210 is provided so that the fitting piece 411 is embedded in the groove, so that the surface of the fitting piece 411 is flush with the surface of the earphone 20, which is not only aesthetically pleasing, but also avoids bumps and knocks.

[0039] like Figure 5As shown, the connecting element 430 includes a connector 431 connected to the headphone charging motherboard 420. The connector 431 has spaced elastic clips 432, forming an insertion space between two spaced elastic clips 432. The connecting pin 412 is movably inserted into this insertion space and held and fixed by the two elastic clips 432. The elastic clips 432 hold the connecting pin 412 to connect the charging piece 410 to the headphone 10, eliminating the need for additional fasteners to fix the charging piece 410, thus facilitating assembly and improving assembly efficiency.

[0040] like Figure 5 As shown, the connecting pin 412 is provided with an annular limiting groove 413; the elastic clip 432 is embedded in the annular limiting groove 413 to constrain the displacement of the connecting pin 412 relative to the earphone 20. The elastic clip 432 cooperates with the annular limiting groove 413 to effectively constrain the position of the charging piece 410 and prevent it from shifting, thereby improving connection stability. This plug-in connection method eliminates the need for soldering between the charging piece 410 and the motherboard, allowing for flexible assembly and easier component replacement.

[0041] like Figure 3 As shown, the bonding spring element 320 includes a mounting base 321 connected to the charging case main board 310, and the mounting base 321 is provided with a bonding spring 322; the cavity 110 is provided with a slot corresponding to the position of the bonding spring 322, and the bonding spring 322 extends through the slot into the cavity 110; when the earphone 20 is placed in the cavity 110, the bonding spring 322 is in contact with the charging pad 410 and conducts electricity. Compared with traditional spring pins, the bonding spring 322 has its own elasticity, eliminating the need for spring assistance, reducing the number of parts and saving production costs. At the same time, because the bonding spring 322 has a large contact area with the charging pad 410, it is more corrosion-resistant, easy to clean, and can make better contact with the charging pad 410 of the earphone.

[0042] like Figure 4 As shown, a storage battery 330 is provided inside the charging compartment 10, and the storage battery 330 is electrically connected to the charging compartment main board 310; the storage battery 330 is connected to a battery main board 340, the battery main board 340 is connected to a charging connector 350, the charging compartment 10 is provided with a charging port, and the charging connector 350 is disposed inside the charging port.

[0043] like Figure 4 As shown, the headphone charging motherboard 420 is connected to the headphone battery 440.

[0044] An external power source is connected to the charging connector 350, and the battery mainboard 340 stores the electricity in the battery 330.

[0045] During charging, the battery 330 delivers electricity through the battery motherboard 340, the bonding spring element 320, and the charging plate 410 to the earphone battery 440 of the earphone 20 for storage.

[0046] like Figure 4 As shown, the charging case 10 is provided with a first magnetic 60, and the earphone 20 is provided with a second magnetic 50; when the first magnetic 60 and the second magnetic 50 are close to each other, they attract each other to constrain the earphone 20 to remain in the cavity 110.

[0047] Furthermore, the first magnetic attractor 60 is a magnet, and the second magnetic attractor 50 is an existing component that attracts the magnet.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
