[0058] The terminology used in the various embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the various embodiments of this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of this disclosure pertain. Terms (such as those defined in a generally used dictionary) are to be interpreted as having the same meaning as in the context of the relevant technical field and are not to be interpreted as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this disclosure.

[0059] Existing waterproof headphone charging cases have a waterproof sleeve on the base of the charging case that covers the housing. The outer perimeter of the waterproof sleeve has a rim that extends downward and covers the outer perimeter of the housing. When the flip cover is closed on the base, a gap is formed at the joint between the base and the flip cover. The rim corresponds to the position of the gap, which can prevent water from entering the headphone charging case through the gap between the base and the flip cover. This is equivalent to setting a sealed waterproof component, i.e., a waterproof sleeve, between the base and the flip cover, thereby achieving the waterproof function.

[0060] It is evident that the waterproof function in existing technologies is achieved by starting with the sealing structure at the connection point, using multiple scattered seals to achieve the waterproof function of the earphone charging case; as is well known, this scattered seal design suffers from poor sealing performance.

[0061] Example 1:

[0062] This disclosure provides an embodiment:

[0063] To address the issue of poor waterproofing performance in existing waterproof charging cases for headphones, this embodiment provides a waterproof charging device for headphones, such as... Figure 1 and 2 The device includes: a first connector 1, a charging module 2, a second connector 3, and a flexible component 4; wherein, the first connector 1 is disposed at one end of the flexible component 4 for holding the earphones; the charging module 2 is disposed within the first connector 1 by means of a screw fastening structure or other connection method for charging the earphones; the second connector 3 is disposed at the other end of the flexible component 4 for forming a sealed space using the flexible component 4 when fastened with the first connector 1. Preferably, in this embodiment, the first connector 1 is preferably an earphone charging case in the prior art; the second connector 3 is preferably a cover in the prior art.

[0064] Furthermore, to fulfill the functions of placing and charging earphones, such as... Figure 2 The charging module 2 includes a battery 201 and a charging circuit board 202. The battery 201 is fixed in the first connector 1 by means of adhesive or other methods. The charging circuit board 202 is installed in the first connector 1 by a bolt fastening structure and is electrically connected to the battery 201. It is used to connect to an external power source through a charging port 1A to charge the battery 201. The first connector 1 is provided with a placement slot 1D for placing earphones. The placement slot 1D is provided with electrodes electrically connected to the charging circuit board 201. The electrodes are electrically connected to the earphones and are used to charge the earphones through the battery 201.

[0065] In this embodiment, as Figure 3 The flexible component 4 is a whole; and for the headphone charging device, the parts that need to be sealed include the external connection port of the charging module 2, and the gap after the first connector 1 and the second connector 3 are fastened together.

[0066] To seal the above gaps, the flexible component 4 in this embodiment, as shown... Figure 3It includes: a first flexible part 401, a second flexible part 402 and a third flexible part 403; wherein, the first flexible part 401 is connected to the first connector 1; one end of the second flexible part 402 is connected to the first flexible part 401; the third flexible part 403 is connected to the other end of the second flexible part 402 and is connected to the second connector 3.

[0067] In order to seal the gap after the first connector 1 and the second connector 3 are fastened together:

[0068] In this embodiment, as Figure 4-6 The first connector 1 has a waterproof protrusion 1B that matches the shape of the first connector 1 on the side facing the second connector 3; the waterproof protrusion 1B is made of the same material as the first connector 1, which can be a rigid material such as ABS that is injection molded.

[0069] To further improve the reliability of the fastening, such as Figure 7 and 8 The second connecting member 3 includes: a cover body 301 and at least one fastening member 302; wherein, the fastening members 302 are evenly distributed on the side of the cover body 301 near the third flexible part 403; the third flexible part 403 is provided with a through hole 403A for the fastening member 302 to pass through; the waterproof protrusion 1B is provided with a fastening part 1BB that matches the number and shape of the fastening members 302 for fastening; preferably, the area of ​​the cover body 301 is larger than the area of ​​the third flexible part 403, and the area of ​​the through hole 403A is smaller than the cross-sectional area of ​​the fastening member 302, thereby improving the waterproof performance.

[0070] Specifically, such as Figure 9 The fastening member 302 has a mating part 302AA at its end near the waterproof protrusion 1B; the mating part 302AA and the fastening part 1BB form a fastening structure. Simultaneously, the fastening connection between the second connecting member 3 and the waterproof protrusion 1B allows the third flexible part 403 to be pressed between the second connecting member 3 and the waterproof protrusion 1B during fastening, thus providing waterproofing.

[0071] Because of the use of flexible material, when the first connector 1 and the second connector 3 are fastened together, the third flexible part 403 is pressed against the waterproof protrusion 1B, causing deformation. At this time, the third flexible part 403 cooperates with the waterproof protrusion 1B, which can be regarded as a cooperation structure between the sealing gasket and the sealing protrusion, thereby increasing the sealing performance.

[0072] Considering that the first flexible part 401 is connected to the first connector 1, there is also a risk of water leakage. In this embodiment, a stepped waterproof structure is provided between the first connector 1 and the first flexible part 401.

[0073] To seal the charging port:

[0074] Please refer to Figure 2 The first connector 1 is provided with a charging hole 1A; the charging hole 1A is connected to the charging circuit board 202 and is used to connect to an external power source; a sealing part 402A is provided on the second flexible part 402; and for ease of use, a recessed area 1C is provided on the side of the first connector 1 near the second flexible part 402, which is used to facilitate the sealing part 402A to seal the charging hole 1A when the second connector 3 is fastened.

[0075] For preferred options, please refer to [the following]. Figure 3 The shape of the sealing part 402A matches the shape of the charging hole 1A, and the sealing part 402A is made of the same flexible material as the flexible part 4, such as silicone.

[0076] In use, due to the use of flexible member 4, the second flexible part 402 not only connects the first flexible part 401 and the third flexible part 403, but also seals the charging port 1A; at the same time, when the first connecting member 1 and the second connecting member 3 are fastened together, such as Figure 10 The mating part 302AA at the top of the fastener 302 and the fastening part 1BB are matched and connected; given that the second flexible part 402 is a flexible part, the cover body 301 can rotate at a small angle relying on the second flexible part 402; and after rotation, the mating part 302AA rotates to the area of ​​the waterproof protrusion 1B where the fastening part 1BB is not provided, such as Figure 4 At point M, the mating part 302AA and the fastening part 1BB are disengaged, so that the first connector 1 and the second connector 3 can be reopened.

[0077] Those skilled in the art will understand that the accompanying drawings are merely schematic diagrams of a preferred embodiment, and the modules or processes shown in the drawings are not necessarily essential for implementing this disclosure.

[0078] Those skilled in the art will understand that the modules in the apparatus of the implementation scenario can be distributed within the apparatus of the implementation scenario as described, or they can be located in one or more apparatuses different from this implementation scenario, with corresponding changes. The modules of the above-described implementation scenario can be combined into one module, or they can be further divided into multiple sub-modules.

[0079] The serial numbers in this disclosure are for descriptive purposes only and do not represent the merits or demerits of the implementation scenario.

[0080] The above disclosure only discloses a few specific implementation scenarios. However, this disclosure is not limited to these. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this disclosure.
