For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figure 1 As shown, the utility model provides an earphone charging box, including a lower shell assembly 100 and an upper cover assembly 200, the upper cover assembly 200 is rotatably connected to the lower shell assembly 100, and the lower shell assembly 100 can be opened or closed by flipping the upper cover assembly 200.

[0043] It should be noted that the upper cover assembly 200 and the lower shell assembly 100 can be rotatably connected via a rotating shaft or via a flexible cloth.

[0044] The lower shell assembly 100 is provided with a receiving cavity. Specifically, the lower shell assembly 100 is a hollow structure having a receiving cavity. The receiving cavity of the lower shell assembly 100 is used to receive components. The lower shell assembly 100 is used to protect the components disposed in the receiving cavity.

[0045] Combination Figure 1 , Figure 3 and Figure 4 The earphone charging box also includes a wireless charging coil 300, a battery 400 and a main board 500. The wireless charging coil 300, the battery 400 and the main board 500 are all arranged in the accommodating cavity of the lower shell assembly 100. The wireless charging coil 300, the battery 400 and the main board 500 are all placed horizontally, and the wireless charging coil 300, the battery 400 and the main board 500 are arranged in a vertical direction.

[0046] It should be noted that the wireless charging coil 300, the battery 400 and the mainboard 500 are all placed horizontally, which means that the wireless charging coil 300, the battery 400 and the mainboard 500 are all placed flat, that is, the thickness directions of the wireless charging coil 300, the battery 400 and the mainboard 500 are parallel to the vertical direction. It should be noted that within a certain error tolerance range, the wireless charging coil 300, the battery 400 and / or the mainboard 500 may also have a certain inclination angle. In addition, since the wireless charging coil 300, the battery 400 and the mainboard 500 are arranged in the vertical direction, the space occupied by the three in the vertical direction can be saved, thereby making the vertical size of the entire earphone charging box smaller.

[0047] It should be noted that the arrangement order of the wireless charging coil 300, the battery 400 and the mainboard 500 in the vertical direction can be: the wireless charging coil 300, the battery 400 and the mainboard 500 are arranged in sequence from bottom to top, or the wireless charging coil 300, the mainboard 500 and the battery 400 are arranged in sequence from bottom to top, or the battery 400, the wireless charging coil 300 and the mainboard 500 are arranged in sequence from bottom to top, or the battery 400, the mainboard 500 and the wireless charging coil 300 are arranged in sequence from bottom to top, or the mainboard 500, the battery 400 and the wireless charging coil 300 are arranged in sequence from bottom to top, or the mainboard 500, the battery 400 and the wireless charging coil 300 are arranged in sequence from bottom to top.

[0048] It should be noted that the battery 400 and the wireless charging coil 300 are both electrically connected to the mainboard 500, and the wireless charging coil 300 can charge the battery 400 under the action of an external wireless charger. Specifically, the battery 400 and the mainboard 500 can be electrically connected through a battery line 410, and the wireless charging coil 300 and the mainboard 500 can be electrically connected through a coil line 310. In addition, when the wireless charging coil 300, the battery 400 and the mainboard 500 are arranged in a vertical direction, no matter how the positional relationship between the wireless charging coil 300 and the battery 400 is, it should be ensured that the wireless charging coil 300 can charge the battery 400 under the action of an external wireless charger.

[0049] It can be understood that the wireless charging coil 300, the battery 400 and the main board 500 can be stacked on each other, that is, two adjacent components are stacked on each other, so that the vertical space occupied by the wireless charging coil 300, the battery 400 and the main board 500 can be minimized.

[0050] In other embodiments, two adjacent components of the wireless charging coil 300, the battery 400 and the mainboard 500 may be spaced apart to improve the heat dissipation effect of the two adjacent components. In other words, a heat dissipation gap is provided between two adjacent components of the wireless charging coil 300, the battery 400 and the mainboard 500.

[0051] It should be noted that, the spacing between two adjacent components may mean that every two adjacent components are spaced apart from each other, or may mean that only one group of two adjacent components are spaced apart from each other.

[0052] Furthermore, the upper cover assembly 200 is provided with a display screen 700, and the display screen 700 is also electrically connected to the mainboard 500. The mainboard 500 can distribute the power of the battery 400 to the display screen 700 so that the display screen 700 can work normally.

[0053] It should be noted that when the upper cover assembly 200 is in the closed state, the side of the upper cover assembly 200 that is hidden is the inner side of the upper cover assembly 200, and conversely, the side opposite to the inner side of the upper cover assembly 200 is the outer side of the upper cover assembly 200, that is, when the upper cover assembly 200 is in the closed state, the outer side of the upper cover assembly 200 is in an exposed state. The display screen 700 is exposed on the outer side of the upper cover assembly 200, so that when the upper cover assembly 200 is in the closed state, the display screen 700 is in an exposed state, which is convenient for users to observe the display screen 700.

[0054] like Figure 3 As shown, it can be understood that the display screen 700 and the main board 500 are electrically connected through the flexible wire 710, that is, the two ends of the flexible wire 710 are respectively connected to the display screen 700 and the main board 500, so as to achieve electrical conduction between the display screen 700 and the main board 500.

[0055] Combination Figure 1 and Figure 3 It should be noted that the display screen 700 is arranged in the upper cover assembly 200, the main board 500 is arranged in the lower shell assembly 100, and the upper cover assembly 200 is rotatably connected to the lower shell assembly 100. The flexible wire 710 can bend and deform when the upper cover assembly 200 rotates relative to the lower shell assembly 100. In this way, by using the flexible wire 710 to connect the display screen 700 and the main board 500, the reliability of the connection can be guaranteed, and the problem that the hard wire will hinder the rotation of the upper cover assembly 200 or the hard wire is easily broken when the display screen 700 and the main board 500 are connected by using a hard wire can be avoided.

[0056] Furthermore, one end of the flexible wire 710 is connected to the mainboard 500 , and the other end of the flexible wire 710 penetrates into the upper cover assembly 200 from the hinged end of the upper cover assembly 200 and is connected to the display screen 700 .

[0057] First, it should be noted that the hinged end of the upper cover assembly 200 refers to the end at which the upper cover assembly 200 is rotatably connected to the lower shell assembly 100. One end of the flexible wire 710 extends into the accommodating cavity of the lower shell assembly 100 and is connected to the mainboard 500, and the other end of the flexible wire 710 penetrates into the upper cover assembly 200 from the hinged end of the upper cover assembly 200 and is connected to the display screen 700. In this way, the flexible wire 710 can be hidden, which can reduce the risk of the flexible wire 710 being easily torn off due to exposure.

[0058] Specifically, a first opening is provided at a portion of the lower shell assembly 100 close to the hinged end of the upper cover assembly 200, and a second opening is provided at the hinged end of the upper cover assembly 200. One end of the flexible wire 710 extends into the accommodating cavity of the lower shell assembly 100 and is connected to the main board 500, and the other end of the flexible wire 710 passes through the first opening and exits from the lower shell assembly 100, and extends into the interior of the upper cover assembly 200 through the second opening and is connected to the display screen 700.

[0059] It should be noted that the flexible conductor 710 can be a flexible flat cable or a flexible mainboard.

[0060] Combination Figure 1 and Figure 2 In some embodiments, the earphone charging box also includes an interface component 600 disposed in the accommodating cavity of the lower shell component 100, the interface component 600 is electrically connected to the mainboard 500, and a avoidance opening is provided on the side of the lower shell component 100, the interface component 600 is arranged opposite to the avoidance opening, or at least a portion of the interface component 600 is passed through the avoidance opening, and when the interface component 600 is connected to a charger connected to a power source, the battery 400 can be charged.

[0061] In this way, the earphone charging box of the present invention can be used for both wired charging and wireless charging, with a variety of charging methods, and can be adapted to a variety of scenarios.

[0062] Furthermore, the interface assembly 600 includes a carrier plate 610 and an interface body 620 arranged on the carrier plate 610, the carrier plate 610 is located below the main board 500, and a spring piece 630 electrically connected to the interface body 620 is arranged on the carrier plate 610, the spring piece 630 is abutted against the lower side of the main board 500 and electrically connected to the main board 500; wherein, the interface body 620 is arranged opposite to the avoidance opening, or at least a portion of the interface body 620 is passed through the avoidance opening.

[0063] Specifically, a support platform is provided inside the lower shell assembly 100, and the support platform supports the carrier plate 610, and the support platform can also be bonded to the carrier plate 610 or connected by screws or buckles. The carrier plate 610 is used to carry the interface body 620, and the interface body 620 can be electrically connected to the spring 630 through a wire or other conductor. In this way, the spring 630 is electrically connected to the main board 500, and the interface body 620 can be electrically connected to the main board 500. Among them, the interface body 620 is used for inserting the connector of the charger.

[0064] Combination Figure 3 and Figure 5 It should be noted that the carrier plate 610 and the battery 400 are arranged in a horizontal direction, so that the carrier plate 610 can be prevented from occupying additional vertical space of the lower shell assembly 100.

[0065] like Figure 1 As shown, it can be understood that the lower shell assembly 100 includes a lower shell 110, and an earphone support 120 covering an opening on the top of the lower shell 110, and the earphone support 120 and the lower shell 110 together define a accommodating cavity.

[0066] Combination Figure 1 and Figure 2 Specifically, the lower shell 110 is a hollow structure with an opening at the top; the earphone support 120 covers the top opening of the lower shell 110, and the earphone support 120 and the lower shell 110 are jointly arranged to form a accommodating cavity, and the earphone support 120 is used to support the earphone.

[0067] Specifically, the earphone support 120 is also placed horizontally and covers the top opening of the lower shell 110 .

[0068] Furthermore, an earphone slot 121 is provided on the side of the earphone support 120 facing away from the accommodating cavity, and the earphone can be placed in the earphone slot 121 to be restrained, thereby reducing the risk of the earphone moving freely in the earphone charging box.

[0069] Specifically, there are two earphone slots 121 , and the two earphone slots 121 are symmetrically arranged.

[0070] It can be understood that, for a pair of earphones, it includes two earphone monomers 800, and the two earphone monomers 800 can be placed in two earphone slots 121 respectively.

[0071] It should be noted that the shape of the earphone slot 121 can be configured to accommodate open earphones or in-ear earphones. In addition, the earphone can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function, and at the same time, can also be configured with stereo surround and other functions.

[0072] Furthermore, a through hole is provided at the bottom of the earphone slot 121, and a charging column 510 is provided on the mainboard 500. The charging column 510 passes through the through hole. When the earphone is placed in the earphone slot 121, the charging terminal on the earphone is connected to the charging column 510, so that the battery 400 can charge the earphone.

[0073] Specifically in this embodiment, the shape of the earphone slot 121 is configured to accommodate an open earphone, and the open earphone has an earphone body 810 and an ear hook 820 connected to the earphone body 810.
