[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Please refer to Figure 1 , Figure 1 This is a structural block diagram of an earphone charging box provided by an embodiment of the present invention. The earphone charging box may include: a communication connection component 10, a first signal link 20, a second signal link 30, an antenna component 40 and a power supply component 50;

[0039] The communication connection component 10 is used to connect with the hotspot terminal, receive the first signal sent by the hotspot terminal, and transmit the second processed signal sent by the second signal link 30 to the hotspot terminal;

[0040] The first signal link 20 is connected to the communication connection component 10 and the antenna component 40 respectively, and is used to perform signal amplification processing on the first signal to obtain a first processed signal, and send the first processed signal to the target terminal through the antenna component 40;

[0041] The second signal link 30 is connected to the communication connection component 10 and the antenna component 40 respectively, and is used to amplify the second signal sent by the target terminal received by the antenna component 40 to obtain a second processed signal, and send the second processed signal to the hotspot terminal through the communication connection component 10; wherein a wireless hotspot connection is established between the hotspot terminal and the target terminal;

[0042] The power supply component 50 is used to use the battery in the earphone charging box to power the first signal link 20, the second signal link 30 and the communication connection component 10.

[0043] It can be understood that the hotspot terminal in this embodiment can be a terminal device that turns on the wireless hotspot, such as a smart phone; the target terminal in this embodiment can be a terminal device connected to the wireless hotspot turned on by the hotspot terminal, that is, a wireless hotspot connection is established between the hotspot terminal and the target terminal. The purpose of this embodiment can be to add a hotspot amplification function to the earphone charging box (such as a TWS charging box) so that the hotspot terminal can use the earphone charging box to wirelessly communicate with the target terminal after the wireless hotspot is turned on, and the communication signal between the hotspot terminal and the target terminal is amplified by the earphone charging box, that is, the hotspot terminal only needs to receive and send signals, and the earphone charging box completes the signal amplification, and uses the battery provided in the earphone charging box itself to power the hotspot terminal, so that after the wireless hotspot is turned on, the hotspot terminal will only consume a small amount of electricity, and most of the power consumption is provided by the earphone charging box, which improves the battery life and heating performance of the hotspot terminal.

[0044] Specifically, the first signal in this embodiment can be a signal that the hotspot terminal needs to send to the target terminal via a wireless hotspot connection, the first processed signal can be a signal obtained after the first signal link 20 performs signal amplification processing on the first signal, and the second signal can be a signal that the target terminal needs to send to the hotspot terminal via a wireless hotspot connection, and the second processed signal can be a signal obtained after the second signal link 30 performs signal amplification processing on the second signal.

[0045] Correspondingly, for the specific signal types of the first signal and the second signal in this embodiment, as well as the specific type of the wireless hotspot connection established between the hotspot terminal and the target terminal, the designer can set it according to the practical scenario and user needs. For example, when the target terminal accesses the network through the hotspot opened with the hotspot terminal, the first signal can be a downlink network signal, the second signal can be an uplink network signal, and the wireless hotspot connection can be a WiFi connection; for example, when the target terminal accesses the Internet through the WiFi hotspot opened by the hotspot terminal, the downlink network signal can be transmitted from the network to the target terminal through the hotspot terminal, the communication connection component 10, the first signal link 20 and the antenna component 40 in sequence; the uplink network signal can be transmitted from the target terminal to the network through the antenna component 40, the second signal link 30, the communication connection component 10 and the hotspot terminal in sequence. When the target terminal accesses the network through the hotspot opened with the hotspot terminal, the first signal can be a downlink network signal, the second signal can be an uplink network signal, and the wireless hotspot connection can also be a Bluetooth connection, that is, the target terminal can access the Internet through the Bluetooth hotspot opened by the hotspot terminal. As long as the hotspot terminal can use the connected earphone charging box to complete the communication of the wireless hotspot connection with the target terminal, this embodiment does not impose any restrictions on this.

[0046] It should be noted that the communication connection component 10 provided in the headset charging box in this embodiment can receive the first signal sent by the hotspot terminal through the connection with the hotspot terminal, and send the second processing signal to the hotspot terminal. The specific device type of the communication connection component 10 in this embodiment, that is, the specific connection method between the communication connection component 10 and the hotspot terminal, can be set by the designer according to the practical scenario and user needs. For example, the communication connection component 10 can be a USB connection component, that is, the communication connection component 10 can be connected to the hotspot terminal via a USB wired connection through the USB interface (such as a Type C interface) it contains; the communication connection component 10 can also be a wireless connection component (such as a Bluetooth connection component), that is, the communication connection component 10 can be connected to the hotspot terminal wirelessly. As long as the communication connection component 10 can receive the first signal sent by the hotspot terminal through the connection with the hotspot terminal, and send the second processing signal to the hotspot terminal, this embodiment does not impose any restrictions on this.

[0047] Correspondingly, the specific circuit structure and type of the first signal link 20 and the second signal link 30 in this embodiment can be set by the designer. For example, when the first signal is a downlink network signal and the second signal is an uplink network signal, the first signal link 20 can be specifically a downlink network signal link for amplifying the downlink network signal, and the second signal link 30 can be specifically an uplink network signal link for amplifying the uplink network signal. The first signal link 20 and the second signal link 30 can both include an amplifier for amplifying the signals received by each. The first signal link 20 and the second signal link 30 can also both include a signal filter for filtering the signals received by each, that is, the signals received by the first signal link 20 and the second signal link 30 can first be filtered by a signal filter and then amplified by an amplifier to complete the signal amplification process. Figure 2 As shown, the downlink network signal link may include a downlink signal filter and an amplifier. The downlink network signal (first signal) sent by the smart phone (hotspot terminal) is first filtered by the downlink signal filter, and then the filtered downlink network signal is amplified by the amplifier to obtain a first processed signal and output to the target terminal through the metal antenna of the antenna component 40; the uplink network signal link may include an uplink signal filter and an amplifier. The uplink network signal (second signal) of the target terminal received by the metal antenna of the antenna component 40 is first filtered by the uplink signal filter, and then the filtered uplink network signal is amplified by the amplifier to obtain a second processed signal and output to the smart phone. As long as the first signal link 20 and the second signal link 30 can amplify the signals received by each other to ensure the signal stability of the communication between the hotspot terminal and the target terminal, this embodiment does not impose any restrictions on this.

[0048] Specifically, the specific connection relationship between the communication connection component 10 and the first signal link 20 and the second signal link 30 in this embodiment can be set by the designer. For example, the communication connection component 10, the first signal link 20 and the second signal link 30 are set in accordance with their respective positions in the charging box. When the communication connection component 10 and the first signal link 20 and the second signal link 30 are set on different PCBAs (printed circuit boards), the FPC (flexible circuit board) of the board can be used to connect the communication connection component 10 to the first signal link 20 and the second signal link 30. That is, the earphone charging box also includes: a communication PCBA provided with the communication connection component 10; wherein the communication PCBA is connected to the main PCBA (i.e., main board) provided with the first signal link 20 and the second signal link 30 through an FPC, and the communication connection component 10 is specifically used to send a first signal to the first signal link 20 and receive a second processed signal sent by the second signal link 30 through the FPC connection between the communication PCBA and the main PCBA. Figure 3 As shown, the data transmission between the mainboard provided with the first signal link 20 and the second signal link 30 and the Type C PCBA provided with the Type C connection component is connected through the FPC. As long as the communication connection component 10 can output the first signal to the first signal link 20 and receive the second processed signal output by the second signal link 30, this embodiment does not impose any restrictions on this.

[0049] It is understandable that the antenna component 40 in this embodiment may include a metal antenna, so that the first processed signal output by the first signal link 20 is output to a free field by using the metal antenna for reception by the target terminal, and the second signal sent by the target terminal is received from the free field and output to the second signal link 30. This embodiment does not limit the number of metal antennas in the antenna component 40, and the antenna component 40 may be provided with one metal antenna or multiple metal antennas.

[0050] Specifically, the specific structure and setting position of the antenna component 40 in this embodiment can be set by the designer according to practical scenarios and user needs. For example, the metal antenna in the antenna component 40 can be directly set in the antenna routing area inside the charging box shell of the earphone charging box, and connected to the first signal link 20 and the second signal link 30 through the antenna connecting component in the antenna component 40; in order to improve the performance of the amplified hotspot function of the earphone charging box, the antenna component 40 may include a preset number of foldable antenna assemblies, so as to utilize the flippable or slidable connection between the antenna shell provided with a metal antenna in the foldable antenna assembly and the charging box shell. When the amplified hotspot function of the earphone charging box is used, the signal transmission performance of the metal antenna is better.

[0051] Correspondingly, when the antenna shell in which a metal antenna is provided in the foldable antenna assembly is flipably connected to the charging box shell, each foldable antenna assembly may include: an antenna shell, a metal antenna in the antenna routing area provided in the antenna shell, and an antenna connecting component; the metal antenna is respectively connected to the first signal link 20 and the second signal link 30 through the antenna connecting component, and a rotating PIN insertion hole is provided on the antenna connecting side of the antenna shell; correspondingly, the earphone charging box may also include: a charging box shell and a preset number of rotating PINs; the charging box shell is provided with rotating PIN matching holes corresponding to each foldable antenna assembly; the rotating PIN insertion hole on each antenna shell is connected to the corresponding rotating PIN matching hole through a rotating PIN, so that the antenna shell can be flipped outward.

[0052] The antenna connection component may be a component in the foldable antenna assembly for connecting the metal antenna with the first signal link 20 and the second signal link 30, such as Figure 3 and Figure 4 As shown, the antenna connection component may include an antenna coaxial cable, an antenna coaxial cable male connector and an antenna coaxial cable female connector. By connecting the antenna coaxial cable male connector to the corresponding antenna coaxial cable female connector on the mainboard, the metal antenna in the foldable antenna assembly can be connected to the first signal link 20 and the second signal link 30 on the mainboard. The antenna connection side where the rotating PIN insertion hole on the antenna housing is located can be a side of the antenna housing that leads out the antenna connection component, such as Figure 4 One side of the antenna coaxial cable is led out of the antenna housing, so that the antenna housing can be turned outward with the rotating PIN inserted in the rotating PIN insertion hole as the axis; Figure 5 As shown, the antenna shells of the two foldable antenna assemblies can be symmetrically arranged on both sides of the charging box shell, so that when the user uses the amplified hotspot function of the earphone charging box, the antennas on both sides of the earphone charging box can be unfolded to make the signal transmission performance of the metal antenna better; when the amplified hotspot function of the earphone charging box is not used, the antenna can be folded back onto the earphone charging box for easy carrying.

[0053] Correspondingly, such as Figure 6 As shown, each rotating PIN can be provided with a protruding structure, which is used to form an interference fit with the rotating PIN when connecting the corresponding rotating PIN insertion hole on the antenna housing and the rotating PIN matching hole on the charging box housing, so that the antenna housing can stay in any flipping position, thereby allowing the antenna housing to remain in a fixed position without being affected by external forces.

[0054] Specifically, the earphone charging box in this embodiment may further include an inner bracket, on which a plurality of Boss columns are provided for fixing a mainboard provided with a first signal link 20 and a second signal link 30 and a communication PCBA provided with a communication connection component 10; Figure 7 and Figure 3 As shown, four Boss columns can be set on the inner bracket, so that the motherboard and Type C PCBA can be fixed to the inner bracket through the motherboard fixing screws and the Type C PCBA fixing screws.

[0055] It should be noted that the power supply component 50 in this embodiment can use the battery in the charging box to power the first signal link 20, the second signal link 30 and the communication connection component 10 after the hotspot amplification function of the earphone charging box is activated.

[0056] Furthermore, when the communication connection component 10 is a USB connection component, the power supply component 50 can also use the battery in the earphone charging box to supply power to the target terminal through the USB connection component, so that the earphone charging box can supply power to the target terminal such as a mobile phone.

[0057] In this embodiment, the embodiment of the present invention adds a hotspot amplification function to the earphone charging box, so that the user does not need to carry an additional portable hotspot device, thereby improving the product utilization rate of the earphone charging box and improving the user experience; and utilizing the first signal link 20 and the second signal link 30 provided in the earphone charging box to amplify the communication signal between the hotspot terminal and the target terminal for establishing a wireless hotspot connection, thereby improving the signal strength and stability; and utilizing the power supply component 50 provided in the earphone charging box to power the first signal link 20, the second signal link 30 and the communication connection component 10 using the battery in the earphone charging box, the power consumption and heat generation of the hotspot terminal when the hotspot is turned on can be reduced, so that the hotspot terminal has better battery life and heating performance.

[0058] In addition, an embodiment of the present invention further provides a portable hotspot system, comprising: a hotspot terminal, a target terminal, and an earphone charging box as provided in the above embodiment;

[0059] Among them, the hotspot terminal is connected to the earphone charging box, and the hotspot terminal establishes a wireless hotspot connection with the target terminal; the hotspot terminal is used to communicate with the target terminal through the wireless hotspot connection using the earphone charging box.

[0060] Optionally, the hotspot terminal may be specifically a mobile phone, and the wireless hotspot connection between the hotspot terminal and the target terminal may be specifically a WiFi connection.
