Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Firstly, this utility model provides a router charging circuit.

[0034] See Figure 1 The present invention provides a router charging circuit, which specifically includes:

[0035] Power interface 10, transmitting circuit 11, rectifier and voltage regulator circuit 12, charging management circuit 13, MCU, backup power module 14, switch button 3 and manual switch 15;

[0036] The power interface 10, switch button 3, and manual switch 15 are all fixed to the router's outer casing 1, while the transmitting circuit 11, rectifier and voltage regulator circuit 12, charging management circuit 13, MCU, and backup power module 14 are all fixed inside the router's outer casing 1. Specifically, the connection relationships between the components are as follows:

[0037] Power interface 10 is connected to transmitting circuit 11, and is used to connect an external power source to power the entire router charging circuit. Transmitting circuit 11 is connected to the MCU and rectifier / regulator circuit 12. Transmitting circuit 11 filters, adjusts, and amplifies the power supply voltage signal before outputting it to rectifier / regulator circuit 12. Rectifier / regulator circuit 12 rectifies and regulates the power supply voltage signal, outputting a stable current signal. Rectifier / regulator circuit 12 is connected to the MCU and charging management circuit 13. Charging management circuit 13 is connected to backup power module 14 and the MCU. Charging management circuit 13 monitors the power level of backup power module 14 in real time and sends corresponding control commands to the MCU based on the power level of backup power module 14. The MCU controls the transmitting circuit 11 and rectifier / regulator circuit 12 to perform corresponding operations based on the control commands. Backup power module 14 is connected to the router and provides power to the router during power outages. MCU is connected to switch button 3, which is used to turn on the router and the MCU. The manual switch 15 is connected to the backup power module 14, and the manual switch 15 is used to turn the backup power module 14 on and off.

[0038] The router can be powered externally via power interface 10; simultaneously, the transmitting circuit 11 is also powered externally via power interface 10. When switch button 3 is turned on, the charging management circuit 13 first detects the power level of the backup power module 14 and determines whether charging is needed. When charging is needed, the charging management circuit 13 sends a charging command to the MCU, which then controls the transmitting circuit 11 and the rectifier-regulator circuit 12 to start operating. The transmitting circuit 11 filters, adjusts, and amplifies the power voltage signal before outputting it to the rectifier-regulator circuit 12. The current signal output after processing by the rectifier-regulator circuit 12 enters the charging management circuit 13, and is then output to the backup power module 14 to begin charging. During charging, the charging management circuit 13 continuously monitors the power level of the backup power module 14. When fully charged, the charging management circuit 13 sends a stop charging command to the MCU, which then controls the transmitting circuit 11 and the rectifier-regulator circuit 12 to stop operating. In case of power outages or other emergencies, pressing the manual switch 15 to turn on the backup power module 14 will provide power to the router. The backup power module 14 can be implemented using existing technologies, such as lithium batteries.

[0040] The specific parameters of each device are as follows:

[0041] The first chip U1 can be implemented using the AD9851 chip. After the power supply voltage signal is regulated and amplified by the AD9851 chip, the output sine wave or square wave signal is further filtered by a low-pass filter circuit composed of resistor R7 (seventh resistor), resistor R8 (eighth resistor), capacitors C1 to C5 (first capacitor), inductor L1, and inductor L2. The output signal voltage value is then sent to the rectifier and voltage regulator circuit 2. The first diode D1 mainly stabilizes the voltage; while the first inductor L1 and the second inductor L2 mainly filter, filter noise, stabilize current, and suppress electromagnetic interference. The first inductor L1 and the second inductor L2, together with capacitors C1 to C5, form an LC filter circuit, which suppresses higher-frequency interference signals, thereby outputting a relatively pure DC current signal.

[0043] The capacitance values ​​of the first capacitor C1 to the fifth capacitor C5 are 2.2P, 3.3P, 22P, 33P, and 22P, respectively.

[0044] like Figure 2 As shown, the rectifier and voltage regulator circuit 12 mainly consists of a ninth resistor R9, a second diode D2, sixth capacitors C6 through ninth capacitors C9, and a third inductor L3. The ninth resistor R9, second diode D2, and sixth capacitors C6 through ninth capacitors C9 are connected in parallel. The third inductor L3 is connected to the seventh capacitor C7 and the eighth capacitor C8, respectively. The ninth capacitor C9 is connected to the eighth resistor R8. Simultaneously, the connection terminals of the seventh capacitor C7 and the eighth capacitor C8 are connected to the MCU. The interaction between the ninth resistor R9, second diode D2, sixth capacitors C6 through ninth capacitors C9, and third inductor L3 achieves rectification and voltage regulation of the power supply voltage signal to output a stable current signal. Among these, the eighth capacitor C8 serves as a filter capacitor, the ninth capacitor C9 can suppress high-frequency interference, the seventh capacitor C7 can prevent self-oscillation that may occur from the leads, the sixth capacitor C6 can reduce the ripple voltage in the output voltage, and the second diode D2 serves as a protection diode to prevent damage to the sixth capacitor C6 due to discharge when the input terminal is short-circuited.

[0048] like Figure 2As shown, the charging management circuit 13 mainly consists of capacitors C10 to C12 (tenth to twelfth), resistors R10 to R12 (tenth to twelfth), diode D3 and diode D4 (fourth), and chip U2. One end of the parallel connection of capacitors C10, R10, and C11 is connected to pin 5 of chip U2. Simultaneously, the other end of the parallel connection of capacitors C10, R10, and C11 is connected to the backup power module 4. Pin 2 of chip U2 is connected to the MCU. Pin 4 of chip U2 is connected to resistor R11. The eleventh resistor R11 is connected to the ninth resistor R9, the second diode D2, the sixth capacitor C6, the seventh capacitor C7, and the third inductor L3. The eighth pin 8 of the second chip U2 is connected to the negative terminal of the fourth diode D4, and the positive terminal of the fourth diode D4 is connected to the seventh pin 7 of the second chip U2. The negative terminal of the fourth diode D4 is also connected to the eleventh resistor R11. The sixth pin 6 of the second chip U2 is connected to the twelfth resistor R12. The twelfth resistor R12 is connected to the positive terminal of the third diode D3, and the negative terminal of the third diode D3 is connected to the twelfth capacitor C12 and the eleventh resistor R11. Real-time detection of the power level of the backup power module 14 is achieved through the interaction between the tenth capacitor C10 to the twelfth capacitor C12, the tenth resistor R10 to the twelfth resistor R12, the third diode D3, the fourth diode D4, and the second chip U2. Simultaneously, corresponding control commands can be sent to the MCU based on the power level of the backup power module 14. In this circuit, both the third diode D3 and the fourth diode D4 serve as charging status indicator lights for the second chip U2. Specifically, the third diode D3 can be set to red to indicate that it is in charging mode, and the fourth diode D4 can be set to green to indicate that charging is complete. During the charging process, if the charging current exceeds the set range or a short circuit occurs, the second chip U2 can automatically cut off the input power supply, thereby protecting the backup power module 4.

[0049] The specific parameters of each device are as follows:

[0050] The second chip, U2, can be implemented using the TP4056 chip.

[0051] The resistance values ​​of the tenth resistor R10 to the twelfth resistor R12 are 1K, 10K, and 10K respectively.

The USB interface 7 is fixed to the right side of the housing 1, while the WAN interface 8, LAN interface 9, and power interface 10 are all fixed to the rear surface of the housing 1. The hinge mounting base 6, fixed to the rear surface of the housing 1, is used to mount the antenna 2. The lower end of the antenna 2 is mounted on the hinge mounting base 6 via the hinge 5, allowing the antenna 2 to fold around the hinge 5 onto the upper surface of the housing 1. The number of antennas 2, hinges 5, and hinge mounting bases 6 is the same. The number of antennas 2 can be set according to actual needs; in this embodiment, there are four antennas 2.
