[0002] With the rapid development of wireless headphone technology, open-back headphones and ear-clip headphones have gradually become popular choices in sports scenarios due to their comfort and good breathability.

[0003] Existing wireless earphones use Pogo pin technology for charging. However, this pin-type charging method is not very sweat-proof and waterproof. After the user wears it for exercise, sweat can easily penetrate into the earphone from the charging metal core of the earphone body, causing the internal electronic components to be corroded and the earphone cannot be charged normally.

[0004] The charging pins in the charging case will be corroded due to condensation of sweat, and friction will be generated, causing the pins to be unable to bounce up, affecting the charging case's ability to charge the earphones.

[0005] The existing needle-type charging method has a small contact surface and is not easy to clean; the surface of the charging metal core is easily covered with impurities, affecting effective charging. Summary of the invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an earphone charging structure.

[0016] Preferably, the connecting pin is provided with an annular limiting groove;

[0017] The elastic clip is embedded in the annular limiting groove to restrict the connection pin from moving relative to the earphone.

[0018] Preferably, the bonding conductive element comprises a mounting seat connected to the mainboard of the charging compartment, and the mounting seat is provided with a bonding spring sheet;

[0019] The cavity is provided with a slot corresponding to the position of the fitting elastic sheet, and the fitting elastic sheet extends through the slot into the cavity;

[0042] See also Figure 1-Figure 6 A headset charging structure includes a charging compartment 10 and a headset 20. The charging compartment 10 is provided with a cavity 110. The headset 20 can be placed in the cavity 110.

[0043] A charging module 40, wherein the charging module 40 at least includes an earphone charging mainboard 420 disposed on the earphone 20, and two charging sheets 410 are disposed on the outer wall of the earphone 20, and the charging sheets 410 are electrically connected to the earphone charging mainboard 420;

[0044] The conductive module 30 at least includes a charging compartment mainboard 310 disposed on the earphone 20; two elastic sheet elements 320 are disposed in the cavity 110, and the elastic sheet elements 320 are electrically connected to the charging compartment mainboard 310;

[0045] When the earphone 20 is placed in the cavity 110 , the elastic sheet element 320 and the charging sheet 410 are in contact with each other for electrical conduction.

[0046] In the present invention, the sheet-type contact conduction adopted can effectively improve the waterproof performance of the earphone part and realize structural waterproofness. The fitting contact conduction adopted can prevent sweat from penetrating into the earphone; protect the internal module from being soaked and corroded by sweat, so that normal charging can be achieved.

[0047] As for the charging compartment, the spring element of the charging compartment has high elasticity, and its reliability and durability are better than those of traditional spring pins. The spring element has a larger area, which is quite different from the spring pin in structure and principle. It has its own elastic force and does not require spring assistance. Due to its larger area, it is more corrosion-resistant and easy to clean, and can better contact with the charging plate of the headset to ensure effective charging.

[0048] like Figure 4 and Figure 5 As shown, the earphone charging mainboard 420 is provided with a connecting element 430; the charging sheet 410 includes a fitting sheet 411 provided on the outer wall of the earphone 20, and the fitting sheet 411 is provided with a connecting pin 412, and the connecting pin 412 is detachably connected to the connecting element 430. Plug-in assembly is not only convenient for assembly but also can improve assembly efficiency, optimize the assembly process, and thus improve production efficiency.

[0049] 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 that is interconnected with the interior of the earphone 20; the bonding sheet 411 is provided 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 bonding sheet 411 is embedded in the groove so that the surface of the bonding sheet 411 is flush with the surface of the earphone 20, which is not only beautiful in appearance, but also has no protrusion to avoid bumps.

[0050] like Figure 5As shown, the connecting element 430 includes a connecting seat 431 connected to the headset charging mainboard 420, and the connecting seat 431 is provided with elastic clips 432 at intervals, and a plug-in space is formed between the two elastic clips 432 at intervals, and the connecting pin 412 is movably plugged into the plug-in space and clamped and fixed by the two elastic clips 432. The elastic clip 432 clamps the connecting pin 412 to connect the charging sheet 410 to the headset 10, so that the charging sheet 410 does not need to be fixed by another fixing part, which has the effect of facilitating assembly and improving assembly efficiency.

[0051] 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 to prevent it from being displaced, thereby improving the connection stability. This plug-in connection method eliminates the need for welding between the charging piece 410 and the motherboard, making assembly flexible and component replacement more convenient.

[0052] like Figure 3 As shown, the bonding spring element 320 includes a mounting base 321 connected to the charging compartment mainboard 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 into the cavity 110 through the slot; when the earphone 20 is placed in the cavity 110, the bonding spring 322 is bonded and conductive with the charging sheet 410. Compared with the traditional elastic needle, the bonding spring 322 has its own elastic force and does not require spring assistance, which reduces the number of parts and saves production costs. At the same time, because the bonding spring 322 has a large contact area with the charging sheet 410, it is more corrosion-resistant and easy to clean, and can better contact with the charging sheet 410 of the earphone.

[0053] like Figure 4 As shown, a battery 330 is arranged in the charging bin 10, and the battery 330 is electrically connected to the charging bin mainboard 310; the battery 330 is connected to the battery mainboard 340, and the battery mainboard 340 is connected to the charging connector 350. The charging bin 10 is provided with a charging port, and the charging connector 350 is arranged in the charging port.

[0054] like Figure 4 As shown, the earphone charging mainboard 420 is connected to an earphone battery 440 .

[0055] The external power source is connected to the charging connector 350 , and the electricity is stored in the battery 330 via the battery main board 340 .

[0056] When charging, the storage battery 330 transmits electricity to the earphone battery 440 of the earphone 20 through the battery main board 340, the elastic sheet element 320, and the charging sheet 410 for storage.

[0057] like Figure 4 As shown, the charging case 10 is provided with a first magnetic component 60, and the earphone 20 is provided with a second magnetic component 50; when the first magnetic component 60 and the second magnetic component 50 are close to each other, the two are attracted to each other to constrain the earphone 20 to remain in the cavity 110.

[0058] Furthermore, the first magnetic attraction member 60 is a magnet, and the second magnetic attraction member 50 is an existing element that attracts the magnet.
