[0034] Combine the following Figure 1-Figure 11 The power supply system of a drone according to an embodiment of the present invention is described.

[0035] The embodiment of the first aspect of the present invention provides a drone power supply system, such as Figures 4 to 10 As shown, the drone power system includes a housing 100 , a high-voltage board 200 and a signal board 300 .

[0036] Among them, the shell 100 has a first surface 110 and a second surface 120 relative to each other, the strong current board 200 is arranged on the first surface 110, and the side of the strong current board 200 facing away from the shell 100 has a strong current connection end 210, the number of the strong current connection ends 210 corresponds to the number of drone arms, and the strong current connection end 210 is used to connect the strong current interface of the corresponding electric adjustment of the arm; the signal board 300 is arranged on the second surface 120, and the side of the signal board 300 facing away from the shell 100 has a signal connection end 310, the signal connection end 310 corresponds to the number of arms, and the signal connection end 310 is used to connect the signal interface of the corresponding electric adjustment of the arm.

[0037] It can be understood that the shell 100 integrates a high-power board 200 and a signal board 300, and the high-power board 200 and the signal board 300 are arranged on two opposite surfaces of the shell 100, and a high-power connection terminal 210 is integrated on the high-power board 200, and the high-power connection terminal 210 is used to connect to the high-power interface of the electric regulator, and the electric regulator is connected to the motor of the drone arm to provide power to the motor; the signal board 300 is integrated with a signal connection terminal 310, and the signal connection terminal 310 is connected to the signal interface of the electric regulator to regulate the electrical signal to control the speed of the motor.

[0038] It should be noted that the drone has an arm with a motor installed on it. The motor is the power source of the drone and is responsible for generating lift and other necessary power. The motor works under the control of an electric regulator, which can be supported by the arm.

[0039] It can be understood that each arm has a motor and an electric regulator. When the drone has multiple arms, the number of motors and electric regulators is multiple. Correspondingly, the number of strong current connection terminals 210 and signal connection terminals 310 is multiple. Therefore, the number of strong current connection terminals 210 and signal connection terminals 310 is equal to the number of drone arms, and each strong current connection terminal 210 and signal connection terminal 310 is connected to the electric regulator on the corresponding arm.

[0040] The drone power supply system provided by the embodiment of the present invention integrates the strong power connection terminal 210 through the strong power board 200 and the signal connection terminal 310 through the signal board 300, thereby reducing the internal messy wiring harness, and the strong power board 200 and the signal board 300 are arranged on two opposite surfaces of the shell 100, thereby avoiding the connection cables of the strong power connection terminal 210 and the connection cables of the signal connection terminal 310 from being entangled with each other, thereby reducing the difficulty of installation and maintenance.

[0041] It should be noted that the UAV power supply system provided in the embodiment of the present invention has a simple structure, is easy to disassemble and assemble, and has low maintenance costs; and by arranging the high-voltage board 200 and the signal board 300 on two opposite surfaces of the shell 100, it can save equipment installation space; in addition, the UAV power supply system of this embodiment can be used for the current and electrical regulation signal distribution of air-to-ground collaborative tethered fire-fighting UAVs.

[0042] According to an embodiment of the present invention, a connection port is provided on the strong current board 200, a first end of a strong current connection terminal 210 is connected to the connection port, and a second end of the strong current connection terminal 210 has a plug-in portion, and the plug-in portion is used to connect to a strong current interface of an electric regulator. It should be noted that the first end of the strong current connection terminal 210 is an end close to the center of the housing 100, and the second end of the strong current connection terminal 210 is an end away from the center of the housing 100.

[0043] For example, the connection port is a welding port arranged on the high-voltage board 200, and the first end of the high-voltage connection terminal 210 has a welding portion connected to the welding port, which is welded to the welding port through the welding portion to realize the electrical connection between the high-voltage connection terminal 210 and the high-voltage board 200, and the plug-in portion of the second end of the high-voltage connection terminal 210 can be a high-voltage female plug connector, and the high-voltage interface of the electric regulator is connected to one end of the high-voltage current line, and the other end of the high-voltage current line is connected to a high-voltage male plug connector that cooperates with the high-voltage female plug connector, and the connection between the high-voltage male plug connector and the high-voltage female plug connector can be realized.

[0044] Optionally, the arrangement of the signal connection terminal 310 and the signal board 300 can be the same as the arrangement of the strong current connection terminal 210 and the strong current board 200. Specifically, the signal board 300 has a connection port, the first end of the signal connection terminal 310 is welded to the connection port, and the second end of the signal connection terminal 310 has a plug-in portion, which is used to connect to the signal interface of the electric regulator.

[0045] It should be noted that the signal connection terminal 310 and the signal board 300 can also be arranged in a manner that the signal board 300 has a first connection contact, and the first end of the signal connection terminal 310 has a second connection contact that cooperates with the first connection contact. The electrical connection between the signal connection terminal 310 and the signal board 300 can be achieved through the contact between the first connection contact and the second connection contact. The signal connection terminal 310 can be fixed on the signal board 300 by bonding or mechanical connection.

[0046] It should be noted that in the prior art, the positive and negative poles of the OT terminal are exposed to the outside. During the installation and maintenance process, it is necessary to use screws and nuts to tighten the copper nose interface to achieve circuit connection, which has poor stability and safety. However, the high-voltage board 200 of the present invention integrates the high-voltage connection terminal 210, and the signal board 300 integrates the signal connection terminal 310. The plug-in connection with the electric adjustment can be achieved through the high-voltage connection terminal 210 and the signal connection terminal 310, which has good stability and safety; and the high-voltage board 200 and the signal board 300 are arranged on two opposite surfaces of the housing 100, so that the high-voltage connection terminal 210 and the signal connection terminal 310 are respectively located on both sides of the housing 100. In this way, the high-voltage connection terminal 210 and the signal connection terminal 310 are physically isolated through the housing 100, which effectively prevents mis-insertion, is convenient for plugging and unplugging, and the interface plug-in and unplugging actions are frequent and not easy to be damaged, which is more conducive to electrical maintenance and repair.

[0047] According to an embodiment of the present invention, the high-voltage board 200 is integrated with a welding wire interface for connecting a battery and a power controller, and is connected to a ground power supply device through a cable to continuously supply power to the UAV, thereby improving the UAV's endurance and completing ground-to-air signal transmission.

[0048] In one embodiment of the present invention, Figures 6 to 10 As shown, the shell 100 is annular, and correspondingly, the high-voltage board 200 and the signal board 300 are both annular; the UAV can be a multi-rotor UAV, the UAV includes multiple arms, each arm is provided with an electric regulator, and the UAV includes multiple electric regulators; correspondingly, the high-voltage board 200 has multiple high-voltage connection terminals 210, and the multiple high-voltage connection terminals 210 are arranged along the circumferential direction, and the signal board 300 has multiple signal connection terminals 310, and the multiple signal connection terminals 310 are arranged along the circumferential direction, and the positions of the high-voltage connection terminals 210 and the signal connection terminals 310 correspond to each other.

[0049] Preferably, multiple strong electric connection terminals 210 are evenly distributed along the circumference, multiple signal connection terminals 310 are evenly distributed along the circumference, the number of strong electric connection terminals 210 is equal to the number of signal connection terminals 310, and the strong electric connection terminals 210 and the signal connection terminals 310 correspond to each other in axial position.

[0050] For example, the UAV includes a main body 700 and six arms evenly distributed along the circumference of the main body 700, each arm is provided with an electric regulator and a motor, the high-voltage board 200 has six high-voltage connection terminals 210 evenly distributed along the circumference, and the six high-voltage connection terminals 210 correspond to the six arm positions, and the signal board 300 has six signal connection terminals 310 evenly distributed along the circumference, and the six signal connection terminals 310 also correspond to the six arm positions.

[0051] Optionally, the model of the high-voltage connection terminal 210 can be LCB30, so that the electric speed controller can be connected through LCB30 to evenly distribute power to the six motors; the signal board 300 integrates J30JA-9 and J30JA-15 interfaces, connects the flight control and the electric speed controller, and regulates the electrical signal to control the motor speed.

[0053] Optionally, the first connection portion 130 , the second connection portion 220 and the third connection portion 320 may all be connection holes, and the connection members may be connection screws.

[0054] Furthermore, there is a gap between the second connection part 220 and the connector, and the gap serves as a physical isolation between the second connection part 220 and the connector, so as to avoid the risk of the connector being charged. The second connection part 220 and the third connection part 320 are electrically connected through the connector, so that the strong power board 200 and the signal board 300 are electrically connected, which increases the risk of short circuit and causes fire or equipment damage. It should be noted here that there may also be a gap between the third connection part 320 and the connector to leave a safe distance; of course, there may also be gaps between the second connection part 220 and the connector, and between the third connection part 320 and the connector.

[0055] It should be noted that when the connecting member is connected to the third connecting part 320, the first connecting part 130 and the second connecting part 220, an isolating member may be provided between the second connecting part 220 and the connecting member; of course, an insulating member may also be provided between the third connecting part 320 and the connecting member, and an isolating member may also be provided between the second connecting part 220 and the connecting member, and between the third connecting part 320 and the connecting member.

[0056] Optionally, the shell 100 is provided with a plurality of circumferentially arranged first connection portions 130, the first connection portion 130 is a first through hole opened on the shell 100, the first surface 110 of the shell 100 has a first boss corresponding to the first through hole, the first boss has a second through hole coaxial with the first through hole, the second through hole and the first through hole have the same diameter, the second surface 120 of the shell 100 has a second boss corresponding to the first through hole, the second boss has a step hole, the large end of the step hole is coaxially connected to the first through hole, and the diameters are equal; the third connection portion 320 of the signal board 300 is a connection hole matching the second through hole; the second connection portion 220 of the high-voltage board 200 is a connection hole matching the small end of the step hole.

[0057] For example, the first connection part 130 is located at the inner ring end of the housing 100 close to the center; the third connection part 320 is located at the inner ring edge of the signal board 300, and the third connection part 320 can be a notch sleeved on the first boss, and the second surface 120 of the housing 100 also has a first annular support plate for supporting the signal board 300; the strong current board 200 abuts against the second boss, and the second connection part 220 is a connection hole coaxial with the small end of the step hole, and the first surface 110 of the housing 100 also has a second annular support plate for supporting the strong current board 200, so that the strong current board 200 is supported by the second boss and the second annular support plate. Preferably, the second boss is supported on the inner ring end of the strong current board 200, and the second annular support plate is supported on the outer ring end of the strong current board 200.

[0058] In other embodiments, the first connecting portion 130 of the shell 100 may include two parts, one part of the first connecting portion 130 is used to cooperate with the third connecting portion 320 to achieve the fixation of the signal board 300 on the shell 100; the other part of the first connecting portion 130 is used to cooperate with the first connecting portion 130 to achieve the fixation of the high-voltage board 200 on the shell 100. In this way, the connection position of the signal board 300 on the shell 100 and the connection position of the high-voltage board 200 on the shell 100 are located at different positions of the shell 100, thereby avoiding the risk of electrical connection between the high-voltage board 200 and the signal board 300.

[0059] In one embodiment of the present invention, Figure 5 and Figure 6 As shown, a relay 230 is installed on the side of the high-voltage board 200 facing away from the shell 100, which can significantly improve the flexibility, reliability and safety of the UAV power supply system. The relay 230 can not only realize efficient power supply management, but also provide necessary protection functions to ensure the stable operation of the UAV under various conditions.

[0060] Optionally, the installation height of the relay 230 is slightly higher than the height of the high-voltage board 200 to prevent wear on the high-voltage board 200 during installation and UAV flight.

[0061] In another embodiment of the present invention, a protective resistor 240 is installed on the side of the high-voltage board 200 away from the housing 100, which can improve the safety, stability and reliability of the UAV power system. By limiting transient current and short-circuit current, the protective resistor 240 can effectively protect sensitive components in the circuit and ensure the long-term stable operation of the power system. It should be noted here that the high-voltage board 200 integrates the relay 230 and the protective resistor 240 at the same time, which can prevent hazards such as overload, high temperature, and surge, maximize the safety factor of the product, and make over-power overload protection safer.

[0064] It can be understood that the mounting plate 400 is a ring plate corresponding to the strong current plate 200, and the outer ring surface of the mounting plate 400 is provided with a notch in the radial direction, and the number of the notches is equal to the number of the strong current connection terminals 210, and the positions correspond one to one, and the notch serves as a housing space for the strong current connection terminals 210. It should be noted here that the notch of the mounting plate 400 also provides a connection space for the strong current connection terminals 210 to be plugged in with the electric adjustment.

[0065] In other embodiments, a protrusion may be provided on the housing 100 , and the relay 230 and the protection resistor 240 may be provided on the protrusion to keep a safe distance from the high-voltage board 200 for physical isolation.
