DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings.

[0029] like Figure 1 , 2 As shown, a power bank with integrated signal enhancement function includes a mobile power housing 3.

[0030] The mobile power housing 3 is provided with a power bank module 13 and a signal enhancement host module 19. The mobile power housing 3 is provided with a power switch button 4 for controlling the power bank module on and off. The power bank module has a built-in large-capacity lithium battery, supports fast charging, and can simultaneously power the internal signal enhancement unit and electronic devices such as mobile phones.

[0031] The top of the mobile power housing 3 is provided with a USB interface and a type interface connected to the power bank module. The USB interface is used to power the electronic device, and the type interface is used to support fast charging of the power bank module.

[0032] The signal enhancement host module 19 includes a mode selection module 20, a control unit 15, a GPS signal enhancement unit 17, a mobile phone signal enhancement unit 16 and a built-in output antenna 18. The GPS signal enhancement unit 17 includes a GPS signal enhancement unit switch 21 for controlling the on and off of the GPS signal enhancement unit. The mobile phone signal enhancement unit 16 includes a mobile phone signal enhancement unit switch 26 for controlling the on and off of the mobile phone signal enhancement unit.

[0033] The mobile phone signal external receiving antenna interface 7 is connected to the input end of the mobile phone signal enhancement unit 16, and the output end of the mobile phone signal enhancement unit 16 is connected to the built-in output antenna 18. The GPS external receiving antenna interface 6 is connected to the input end of the GPS signal enhancement unit 17, and the output end of the GPS signal enhancement unit 17 is connected to the built-in output antenna 18. The built-in output antenna 18 adopts a broadband antenna.

[0034] The control unit 15 is respectively connected to the mode selection module 20, the GPS signal enhancement unit 17 and the mobile phone signal enhancement unit 16. The mode selection module 20 is connected to the mode selection button 5 provided on the mobile power housing 3, and the mode selection button 5 is used to select to turn on the GPS signal enhancement unit switch or turn on the mobile phone signal enhancement unit switch or turn off the GPS signal enhancement unit switch and the mobile phone signal enhancement unit switch.

[0035] like Figure 3 , 4 As shown, the power bank with integrated signal enhancement function includes the following parts: a mobile power supply shell, a power bank part and a signal enhancement host part.

[0036] In this embodiment, the power supply part is supported by the type interface 10 to support fast charging of the device, the USB interface 9 is used to power electronic devices such as mobile phones, and the built-in large-capacity lithium battery 14 ensures the signal enhancement host 19 and long-term charging endurance. It is equipped with 4 power indicator lights 1 to indicate the power of the power bank. The power switch 4 is used to control the start and stop of the power supply part to save energy.

[0037] In this embodiment, the signal enhancement part is composed of receiving antennas including a GPS signal receiving antenna 11 and a mobile phone signal receiving antenna 12 , a signal enhancement unit host 19 , and an output antenna 18 .

[0038] The working principle of GPS signal enhancement in this example is as follows:

[0039] Select the GPS antenna interface 6 to install the GPS signal receiving antenna 11. After the installation is completed, turn on the power switch 4, select the GPS signal enhancement mode through the mode selection button 5, the control unit 15 turns on the GPS signal enhancement unit switch 21, the GPS signal enhancement unit 17 starts working, and the GPS receiving antenna 11 transmits the received GPS signal to the GPS signal enhancement unit 17. The enhanced signal is distributed to the mobile device through the built-in output antenna 18.

[0040] The working process of the GPS signal enhancement unit in this example is as follows:

[0041] The GPS signal external antenna 11 receives the GPS signal, and the GPS signal is transmitted to the low noise amplifier Low Noise Amplifier (LNA) 22, which amplifies the received weak GPS signal. After LNA amplification, the signal enters the band pass filter (BPF) 23 to filter out non-GPS signals and noise to ensure the quality of the transmitted signal. The signal processed by the BPF is transmitted to the power amplifier 24 to amplify and enhance the GPS signal. It is passed to the output filter 25 module. The function of the output filter 25 is similar to that of the band pass filter 23, but the frequency range is wider, and the linear distortion and harmonic signals introduced by the power amplifier 24 are filtered out, reducing the out-of-band interference of the signal, and further improving the accuracy and stability of GPS positioning.

[0042] The working principle of mobile phone signal enhancement in this example is as follows:

[0043] Select the mobile phone antenna interface to install 7 mobile phone signal receiving antenna 12. After the installation is completed, turn on the power switch 14, select the mobile phone signal enhancement mode through the mode selection button 5, the control unit 15 turns on the mobile phone signal enhancement unit switch 26, the mobile phone signal enhancement unit 16 starts to work, and the receiving antenna transmits the received mobile phone signal to the mobile phone signal enhancement unit 16 for processing. The enhanced signal is distributed to the mobile phone device through the built-in output antenna 18.

[0044] The working process of the mobile phone signal enhancement unit in this example is as follows:

[0045] The mobile phone signal external antenna 12 receives the mobile phone signal, and the mobile phone signal is transmitted to the low noise amplifier Low Noise Amplifier (LNA) 27, which amplifies the received weak mobile phone signal. After LNA amplification, the signal enters the band pass filter (BPF) 28 to filter out the interference and noise of the mobile phone signal to ensure the quality of the transmission signal. The signal processed by the BPF is transmitted to the power amplifier 29 to amplify and enhance the mobile phone signal. It is transmitted to the output filter 30 module for filtering.

[0046] In this example, the GPS signal enhancement unit 17 and the mobile phone signal enhancement unit 16 adopt a dual-channel mode and are integrated in the signal enhancement host. The control unit 15 selects to open the corresponding channel for signal enhancement, effectively avoiding mutual interference between GPS signals and mobile phone signals in different frequency bands.

[0047] In this example, the built-in output antenna 18 is a broadband antenna adapted to output signals of different frequency bands, and is used to output enhanced GPS signals and mobile phone signals.

[0048] In this example, the display 2 is connected to the control unit 15 to display the working mode and the changes before and after the signal enhancement. The user can select a suitable position according to the signal changes and place the device for signal enhancement.

[0049] The power bank with integrated signal enhancement function in this example is equipped with three working modes: GPS signal enhancement mode, mobile phone signal enhancement mode, and charging mode. The mode selection 20 is performed by key 5, and the command is transmitted to the control unit 15 to select the corresponding working mode. No matter which working mode, the charging function can be supported. If only the charging function of the mobile phone is maintained, the signal enhancement unit can be turned off in the charging mode to save power consumption.

[0050] In this example, the control unit 15 uses the automatic gain control (AGC) technology to dynamically adjust the gain of the amplifier based on the strength of the received signal fed back to the control unit 15, so that the output signal is within the set range, avoiding signal distortion caused by excessive signal amplification, and also avoiding signal interference with public facilities in the area.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
