The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0036] It should be noted that, unless they conflict, the various features of the embodiments of the present invention may be combined with each other and are all within the scope of protection of this application. Furthermore, although the functional modules are divided in the device schematic, in some cases, the module division may be different from that in the device. Furthermore, the terms "first," "second," and the like used herein do not limit the order of data or execution; they are merely used to distinguish between identical or similar items with substantially the same functions and effects.

[0037] The embodiment of the present invention provides a charging system, please refer to Figure 1 The charging system 100 includes a drone 10 and a charging platform 20. The drone is equipped with a battery pack 11 and a power receiving interface 12. The output end of the battery pack 11 is connected to the first end a of the power receiving interface 12, and the charging end of the battery pack 11 is connected to the second end b of the power receiving interface 12. The charging platform 20 includes a charging interface 21, a control unit 22, a charging switch 23, and a charging power source 24. The first end a of the charging interface 21 is connected to the power supply end of the control unit 22. The charging switch 23 is connected in series between the charging power source 24 and the second end b of the charging interface 21. The first end of the control unit 22 is connected to the control end of the charging switch 23.

[0038] Among them, the first end a of the charging interface 21 is used to connect to the first end a of the power receiving interface 12, and the second end b of the charging interface 21 is used to connect to the second end b of the power receiving interface 12. In this way, when the drone 10 is connected to the charging platform 20, that is, when the power receiving interface 12 and the charging interface 21 are connected, the battery pack 11 supplies power to the control unit 22, so that the control unit 22 outputs a first control signal to the charging switch 23, thereby turning on the charging circuit formed by the charging power supply 24, the charging switch 23, the second end b of the charging interface 21, the second end b of the power receiving interface 12 and the battery pack 11, so that the charging power supply 24 charges the battery pack 11.

[0039] In the charging system 100, when the drone 10 is connected to the charging platform 20, that is, when the power receiving interface 12 is connected to the charging interface 21, the first end a of the power receiving interface 12 is connected to the first end a of the charging interface 21, and the first end a of the power receiving interface 12 is connected to the second end b of the charging interface 21. The battery pack 11 releases electrical energy through the output end, and the energy flows to the power supply end of the control unit 22 through the power receiving interface 12. Then, after receiving power, the control unit 22 outputs a first control signal to the charging switch 23, turning on the charging switch 23, thereby connecting the charging power source 24 to the charging circuit of the battery pack 11, and the battery pack 11 enters the charging state. Specifically, the power receiving interface 12 and the charging interface 21 can be metal contacts, metal structural members, or any other suitable structure for transmitting electrical energy in the prior art, which is not limited here.

[0040] It can be seen that when the drone is low on battery, it can land in a specific charging area and seek charging on the charging platform 20 provided in the embodiment of the present invention. In this charging method, there is no need to manually replace the drone's battery, which reduces labor costs. In addition, in the charging system 100, the control unit 22 of the charging platform 20 is powered by the drone's battery pack 11, rather than by the charging power supply 24 of the charging platform 20. Using this power supply method to wake up the charging platform 20 not only serves as a presence detection between the drone 10 and the charging platform 20, but also reduces the loss of the charging platform 20 during idle time, allowing the drone to charge autonomously when it lands on the charging platform 20, thereby improving the intelligence of the charging system 100.

[0041] In some other embodiments, the charging platform can omit the charging switch. In this case, the first end of the charging interface is connected to the power supply end of the control unit, the second end of the charging interface is connected to the first end of the charging power supply, and the first end of the control unit is directly connected to the charging power supply. In this case, when the control unit is powered, it can directly control the output of the charging power supply, and then control the charging status of the battery pack.

[0042] In order to facilitate data communication between the drone and the charging platform, in some of the embodiments, please refer to Figure 2The third end c of the charging interface 21 is connected to the communication end of the control unit 22. The third end c of the charging interface 21 is used to connect to the third end c of the power receiving interface 12, which is in turn connected to the communication end of the battery pack 11. Thus, when the power receiving interface 12 is connected to the charging interface 21, the third end c of the power receiving interface 12 is connected to the third end c of the charging interface 21, enabling communication between the drone 10 and the charging platform 20 via the communication port, enabling data communication. In the present invention, the battery pack 11 is capable of data communication and is communicatively connected to the control unit 22. In some embodiments, the battery pack 11 includes a communication port for a wired connection to the third end c of the power receiving interface 12. In other embodiments, the battery pack 11 includes a wireless communication module, such as a Bluetooth module, a cellular module, or a local area network module, enabling direct wireless communication with the control unit 22. In practical applications, the communication connection method between the control unit 22 and the battery pack 11 need not be limited to that described in this embodiment, as long as data communication is possible.

[0043] In some embodiments, in the charging system, when the power receiving interface 12 is connected to the charging interface 21, that is, after a communication connection is established between the drone 10 and the charging platform 20, the battery pack 11 is also used to send the charging parameter information of the battery pack 11 to the control unit 22, and the control unit 22 is also used to receive the charging parameter information of the battery pack 11. Specifically, when the drone 10 is connected to the charging platform 20, after the control unit 22 is powered, the control unit 22 communicates with the battery pack 11 through the communication terminal and obtains the voltage, charging status, power level, and battery model information of the batteries in the battery pack 11. In the subsequent charging process, the control unit 22 can determine the voltage and current output by the charging power supply to the drone battery based on the battery parameter information, thereby ensuring the safety of the battery pack 11 and extending the service life of the battery pack 11.

[0044] In some of these examples, see Figure 3 The battery pack 11 includes a battery 111 and a battery management unit 112. A first end of the battery 111 is connected to a first end of the battery management unit 112, a power supply end of the battery management unit 112 is connected to the flight control module 13, a first end a of the power receiving interface 12 is connected to a second end of the battery 111, a second end b of the power receiving interface 12 is connected to a charging end of the battery management unit 112, and a third end c of the power receiving interface 12 is connected to a communication end of the battery management unit 112.

[0045] The battery management unit 112 is used to control the charging and discharging of the battery 111. In the charging system 100, when the power receiving interface 12 of the drone 10 is connected to the charging interface 21 on the charging platform 20, the battery 111 releases electrical energy through the second end to the power supply end of the control unit 22. The control unit 22 receives power and outputs a first control signal to the charging switch 23, turning on the charging switch 23. This connects the charging power source 24, the charging switch 23, the second end b of the charging interface 21, the second end b of the power receiving interface 12, the battery management unit 112, and the charging circuit of the battery 111. The battery 111 enters a charging state. During the charging process, the control unit 22 communicates with the battery management unit 112 and exchanges data. In the charging system 100, the charging circuit of the battery 111 passes through the battery management unit 112. This allows the battery management unit 112 to provide charging protection during the charging process, ensuring the reliability and safety of the charging system 100.

[0046] In some embodiments, the battery management unit is composed of a microprocessor and a switching circuit. The specific circuit structure can refer to the circuit structure in the prior art and is not limited here. The microprocessor and the control unit can both adopt microcontrollers from the STM8, STM16, or STM32 series, or any other suitable microcontroller or single-chip microcomputer that can receive, process, and output data, without limitation here.

[0047] Typically, when the battery pack is installed on the drone body, it is generally in the state of powering the flight control module and the supply current is relatively high. If charging is performed at this time, it is easy to damage the battery. To avoid such damage, in some embodiments, when the power receiving interface is connected to the charging interface, the control unit is also used to send a shutdown command to the battery management unit before outputting the first control signal. After receiving the shutdown command from the control unit, the battery management unit will control the battery to stop supplying power to the flight control module. It should be noted that please refer to Figure 3 When the power receiving interface 12 is connected to the charging interface 21, the second end of the battery 111 is directly connected to the power supply end of the control unit 22, and the power supply circuit does not pass through the battery management unit 112. Therefore, when the battery management unit 112 executes the shutdown command, it will not affect the power supply of the battery 111 to the control unit 22, and the charging system remains in a normal charging working state.

[0048] In some embodiments, the battery management unit is further configured to detect whether the charging status of the battery is normal when the battery is being charged, and to generate an alarm when the charging status of the battery is abnormal. Specifically, the battery pack further includes a charging current detection unit and a temperature detection unit. The charging current detection unit is connected in series in the charging circuit. The battery management unit is connected to the charging current detection unit and the temperature detection unit, respectively. The temperature detection unit is configured to detect the battery temperature and send the battery temperature to the battery management unit. In this charging system, when the battery is being charged, the battery management unit can detect whether the battery temperature is normal through the temperature detection unit, and whether the charging current is normal through the charging current detection unit. If the battery temperature is not within a preset temperature range, and / or the charging current exceeds a preset current value, an alarm is generated to prevent the battery from overheating or overcharging. It is understandable that the battery management unit can also be used to detect whether there is an abnormality in the charging voltage of the battery pack, whether there is a short circuit during charging, or monitor other events that trigger safety alarms. If an abnormality occurs, an alarm is generated.

[0049] Specifically, in some embodiments, the charging system further includes an alarm device connected to the charge management unit, such as a display screen, at least one LED, a buzzer, a microphone, a vibrator, or any other suitable alarm device. When the battery management unit detects an abnormal charging state of the battery pack, it controls the alarm device to operate. The specific control process of the alarm device by the battery management unit can refer to existing technologies and is not limited here.

[0050] In some embodiments, the battery management unit is also used to send an alarm message to the control unit when an alarm event occurs. The control unit is also used to output a second control signal to the charging switch after receiving the alarm message to disconnect the charging circuit, thereby disconnecting the charging circuit and causing the control unit to control the charging power supply to stop charging the battery pack to ensure system safety.

[0051] To improve system reliability, in some embodiments, the battery management unit is further configured to send a charging completion message to the control unit when battery charging is complete. The control unit is further configured to receive the charging completion message and, based on the charging completion message, output a second control signal to the charging switch to disconnect the charging circuit and control the charging power supply to stop charging the battery pack. Thus, when battery charging is complete, the battery management unit sends the charging completion message to the control unit, which in turn outputs a second control signal to the charging switch to disconnect the charging circuit. Specifically, the charging switch can be a relay, a MOS tube, an IGBT, or any other suitable switching circuit, which is not limited here.

[0052] In order to further improve the intelligence of the system, in some embodiments, after executing the step of disconnecting the charging circuit according to the charging completion information, the control unit also sends a power-on command to the battery management unit. After receiving the power-on command, the battery management unit will re-power the flight control module, so that the drone enters a normal working state, thereby improving the intelligence of the system.

[0053] The following combination Figure 3 The charging system shown in the figure describes in detail the specific working process of the charging system provided by the embodiment of the present invention.

[0054] Please refer to Figure 3 and Figure 4 When the power receiving interface 12 of the drone 10 is connected to the charging interface 21 of the charging platform, the control unit 22 is powered. First, the control unit 22 sends a shutdown command to the battery management unit 112 through the communication terminal. The battery management unit 112 disconnects the power supply from the battery 111 to the flight control module 13 according to the shutdown command. Then, the control unit 22 outputs a first control signal to the charging switch 23, turning on the charging switch 23, thereby connecting the charging circuit of the charging power supply 24, the charging switch 23, the second end of the charging interface 21, the second end of the power receiving interface 12, the battery management unit 112, and the battery 111, and the battery 111 enters the charging state. Then, during the charging process of the battery 111, The battery management unit 112 monitors the charging process of the battery 111. If a safety alarm event occurs, it will sound an alarm to remind manual intervention or send an alarm message to the control unit 22. The control unit 22 will disconnect the charging switch 23 according to the alarm message, thereby disconnecting the charging circuit and protecting the battery 111. When the battery 111 is fully charged, the battery management unit 112 will send a charging completion message to the control unit 22. The control unit 22 will disconnect the charging switch according to the charging completion message and send a power-on command to the battery management unit 112. The battery management unit 112 will re-power the flight control module 13 according to the power-on command, and the drone 10 will enter a normal working state. In summary, it can be seen that in this charging system, there is no need for manual replacement of the drone's battery, and the drone's autonomous charging is highly intelligent.

[0055] The present invention provides a charging platform and an unmanned aerial vehicle (UAV). The charging platform includes a charging interface, a control unit, a charging switch, and a charging power supply. The UAV is provided with a power receiving interface and a battery pack. The first end of the power receiving interface is connected to the output end of the battery pack, and the second end of the power receiving interface is connected to the charging end of the battery pack. The charging switch is connected in series between the charging power supply and the second end of the charging interface. The power supply end of the control unit is connected to the first end of the charging interface, and the first end of the control unit is connected to the control end of the charging switch. When the power receiving interface is connected to the charging interface, the battery pack supplies power to the control unit, and the control unit outputs a first control signal to the charging switch, thereby activating the charging circuit so that the charging power supply charges the battery pack. This charging system does not require manual battery removal and can be autonomously charged, resulting in low labor costs and a high degree of intelligence.
