The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] In the description of the present utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figure 1 , Figure 2 As shown, the utility model provides an earphone charging box, which includes a lower shell component 100 and a charging component 200.

[0039] The lower housing assembly 100 defines a receiving chamber 111 .

[0040] It can be understood that the lower shell assembly 100 is a hollow structure with a receiving cavity 111 , and the top of the lower shell assembly 100 is open.

[0041] The charging assembly 200 is disposed in the accommodating cavity 111 .

[0042] It can be understood that the charging component 200 can charge the earphones. Generally speaking, the charging component 200 includes a battery, a motherboard electrically connected to the battery, and a wireless charging coil electrically connected to the motherboard. In other embodiments, the wireless charging coil can be replaced by a pin.

[0043] Furthermore, the earphone charging box also includes a middle shell 300 arranged in the accommodating cavity 111, the middle shell 300 closes the top opening of the lower shell component 100, the charging component 200 is located on the inner side of the middle shell 300, and an earphone groove 310 is formed on the upper side of the middle shell 300, and the earphone groove 310 is used for inserting the earphone. When the earphone is placed in the earphone groove 310, the charging component 200 can charge the earphone.

[0044] like Figure 2 As shown, the lower shell assembly 100 includes an inner shell 110 defining a housing cavity 111 , and an outer shell 120 sleeved on the inner shell 110 , an interlayer 130 for placing a coolant is defined between the inner shell 110 and the outer shell 120 , and the interlayer 130 is separated from the housing cavity 111 .

[0045] Specifically, the inner shell 110 is a hollow structure with a receiving cavity 111, and the top of the inner shell 110 is open, the outer shell 120 is sleeved on the outer side of the inner shell 110, and an interlayer 130 is formed between the outer shell 120 and the inner shell 110, and the interlayer 130 is used for injecting a coolant, wherein the coolant may be water, alcohol, etc. In addition, the interlayer 130 is separated from the receiving cavity 111, which can prevent the coolant in the interlayer 130 from flowing to the receiving cavity 111 and contaminating the charging assembly 200, thereby damaging the charging assembly 200.

[0046] It is understandable that when the earphone charging box of the present invention is used to charge the earphone, the heat generated by the charging component 200 during the charging process can be absorbed by the coolant, thereby achieving the purpose of dissipating the heat of the charging component 200, and compared with the method of reducing the charging current to improve the problem of the over-high temperature of the charging component 200, the heat dissipation method adopted by the present invention will not affect the charging speed of the earphone charging box. In addition, when the earphone charging box stops working, the heat absorbed by the coolant can be slowly dissipated to the outside world in a natural state, thereby achieving the cooling of the coolant.

[0047] Combination Figure 2 and Figure 3 In some embodiments, the lower shell assembly 100 is further provided with an avoidance channel 140 communicating with the accommodating cavity 111 , the avoidance channel 140 is separated from the interlayer 130 , and the charging assembly 200 has a charging connector 210 penetrating through the avoidance channel 140 .

[0048] It is understandable that the charging connector 210 is connected to the mainboard. When the charging connector 210 is connected to an external power source, the external power source can charge the battery, and the battery can store energy to charge the earphone. By opening the avoidance channel 140 in the lower shell component 100, the charging connector 210 can be exposed to the outside world. In addition, the avoidance channel 140 is separated from the interlayer 130, which can prevent the coolant in the interlayer 130 from flowing out through the avoidance channel 140.

[0049] like Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the inner shell 110 is provided with a first avoidance opening 112, and the outer shell 120 is provided with a second avoidance opening 122 arranged opposite to the first avoidance opening 112, and the edge of the first avoidance opening 112 is provided with a first sealing portion 113 extending toward the outer shell 120, and the first sealing portion 113 is sealed with the outer shell 120, and the mouth wall of the first avoidance opening 112, the inner side wall of the first sealing portion 113, and the mouth wall of the second avoidance opening 122 jointly define an avoidance channel 140.

[0050] Specifically, the first avoidance opening 112 is opened at the bottom of the inner shell 110, and the second avoidance opening 122 is opened at the bottom of the outer shell 120, and the second avoidance opening 122 is arranged opposite to the first avoidance opening 112; the first sealing portion 113 is integrally formed on the inner shell 110, and the first sealing portion 113 is arranged around the first avoidance opening 112 and extends toward the outer shell 120 until it abuts against and is sealed with the outer shell 120, so that the mouth wall of the first avoidance opening 112, the inner side wall of the first sealing portion 113, and the mouth wall of the second avoidance opening 122 jointly define a avoidance channel 140, and the avoidance channel 140 is both connected to the accommodating cavity 111 and separated from the interlayer 130.

[0051] like Figure 6 As shown, further, a first positioning groove 1131 is provided on one side of the first sealing portion 113 close to the housing 120 , and a first positioning portion 121 penetrating into the first positioning groove 1131 is provided on an inner wall of the housing 120 .

[0052] It is understandable that when assembling the outer shell 120 and the inner shell 110 , when the outer shell 120 is sleeved on the inner shell 110 , the first positioning portion 121 can be inserted into the first positioning groove 1131 , thereby achieving positioning of the outer shell 120 and the inner shell 110 .

[0053] Specifically, the first positioning groove 1131 is a closed structure connected end to end, and the first positioning portion 121 is a closed protrusion connected end to end. The first positioning portion 121 is inserted into the first positioning groove 1131, which can also improve the sealing effect between the first sealing portion 113 and the shell 120.

[0054] Please refer to Figure 6In another embodiment, the edge of the second avoidance opening 122 is provided with a second sealing portion extending toward the inner shell 110, and the second sealing portion is sealed with the inner shell 110. The mouth wall of the first avoidance opening 112, the inner side wall of the second sealing portion, and the mouth wall of the second avoidance opening 122 jointly define the avoidance channel 140.

[0055] Specifically, the second sealing portion is integrally formed with the outer shell 120, and the second sealing portion is arranged around the second avoidance opening 122 and extends toward the inner shell 110 until it abuts against and is sealed with the inner shell 110, so that the mouth wall of the first avoidance opening 112, the inner side wall of the second sealing portion, and the mouth wall of the second avoidance opening 122 jointly define an avoidance channel 140, and the avoidance channel 140 is both connected to the accommodating cavity 111 and separated from the interlayer 130.

[0056] Furthermore, a second positioning groove is provided on one side of the second sealing portion close to the inner shell 110 , and a second positioning portion penetrating into the second positioning groove is provided on the outer wall of the inner shell 110 .

[0057] It is understandable that when the outer shell 120 and the inner shell 110 are assembled, when the outer shell 120 is sleeved on the inner shell 110 , the second positioning portion can be inserted into the second positioning groove, thereby achieving positioning of the outer shell 120 and the inner shell 110 .

[0058] Specifically, the second positioning groove is a closed structure connected end to end, the second positioning portion is a closed protrusion connected end to end, and the second positioning portion is inserted into the second positioning groove, which can also improve the sealing effect between the second sealing portion and the shell 120.

[0059] like Figure 4 , Figure 5 As shown, in some embodiments, the lower shell assembly 100 is further provided with a liquid injection port 150 communicating with the interlayer 130 , and an exhaust port 160 communicating with the interlayer 130 .

[0060] It is understandable that coolant can be injected into the interlayer 130 through the injection port 150, and during the process of injecting coolant, the gas in the interlayer 130 will be discharged through the exhaust port 160. When the coolant is injected, the injection port 150 and the exhaust port 160 can be blocked to reduce the risk of coolant leakage.

[0061] It should be noted that the liquid injection port 150 and the exhaust port 160 can be sealed with a plug to achieve sealing of the liquid injection port 150 and the exhaust port 160; or sealant can be applied to the liquid injection port 150 and the exhaust port 160 to achieve sealing of the liquid injection port 150 and the exhaust port 160.

[0062] Combination Figure 7 and Figure 8Furthermore, the top of the inner shell 110 has an extension portion 115 extending toward the outer shell 120 , the extension portion 115 is sealed with the top of the outer shell 120 , and the liquid injection port 150 and the exhaust port 160 are both provided at the extension portion 115 .

[0063] It can be understood that the extension portion 115 is used to seal the top of the interlayer 130, and the injection port 150 is opened on the extension portion 115, which can facilitate the injection of coolant into the interlayer 130 from top to bottom, and the exhaust port 160 is opened on the extension portion 115. Before the interlayer 130 is filled with coolant, the coolant will not flow out through the exhaust port 160.

[0064] Furthermore, a first positioning step 116 is provided at the lower side of the extension portion 115 , and a second positioning step 123 which is positioned and matched with the first positioning step 116 is provided at the top of the housing 120 .

[0065] It can be understood that the first positioning step 116 is arranged around the top opening of the inner shell 110, and the second positioning step 123 is arranged around the top opening of the outer shell 120. The first positioning step 116 and the second positioning step 123 are docked together, thereby further improving the positioning effect of the inner shell 110 and the outer shell 120.

[0066] It should be noted that after the outer shell 120 is sleeved on the outer shell 110, the outer shell 120 and the inner shell 110 can be fixed by ultrasonic welding. Specifically, ultrasonic welding can be performed between the first positioning portion 121 and the first positioning groove 1131, and between the first positioning step 116 and the second positioning step 123, so as to improve the sealing of the interlayer 130. In other embodiments, the outer shell 120 and the inner shell 110 can also be fixed by using a sealant.

[0067] like Figure 2 , Figure 7 As shown, in some embodiments, a glue groove 114 is provided on a side of the extension portion 115 away from the interlayer 130, and the middle shell 300 has an overlapping portion 320 overlapping the extension portion 115, the overlapping portion 320 covers the glue groove 114, and an adhesive layer is provided in the glue groove 114 to seal with the overlapping portion 320.

[0068] It can be understood that the charging component 200 and the middle shell 300 can be pre-assembled together. After the inner shell 110 and the middle shell 300 are assembled, glue can be applied to the glue groove 114, and then the assembly consisting of the charging component 200 and the middle shell 300 can be assembled into the lower shell assembly 100, and the overlapping portion 320 can be overlapped on the extension portion 115. The glue can fix the middle shell 300 and seal the gap between the overlapping portion 320 and the extension portion 115.

[0069] like Figure 1As shown, it should be noted that the earphone charging box also includes an upper cover 400, which is rotatably connected to the middle shell 300 or the lower shell assembly 100, and the upper cover 400 is configured to be open or closed.

[0070] When the earphone charging box of the present invention is charging the earphone, the heat generated by the charging component 200 during the charging process can be absorbed by the coolant, thereby achieving the purpose of dissipating heat for the charging component 200. Moreover, compared with the method of reducing the charging current to improve the problem of the over-high temperature of the charging component 200, the heat dissipation method adopted by the present invention will not affect the charging speed of the earphone charging box. In addition, when the earphone charging box stops working, the heat absorbed by the coolant can be slowly dissipated to the outside world in a natural state, thereby achieving the cooling of the coolant.

[0071] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
