Description

Technical Field

[0001] This application relates to the field of power distribution board technology, specifically to a drone power distribution board and a drone. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices. With the development of the UAV industry, more and more auxiliary devices are being added to UAVs, increasing the demand for power and the number of interfaces. Therefore, it is necessary to install a current distribution board on the UAV body to effectively and rationally distribute power to various devices.

[0003] Most drones on the market currently use removable batteries (i.e., non-smart batteries), and the battery level cannot be read like that of smart batteries. Similarly, existing drone power distribution boards do not have power detection capabilities, leaving users unaware of battery consumption.

[0004] Therefore, it is particularly important to provide a drone power distribution board that can accurately detect real-time power consumption. Utility Model Content

[0015] Preferably, the power interface uses an XT90 terminal, the first ESC power supply interface and the second ESC power supply interface use XT60 terminals, and the first power supply interface and the second power supply interface use XT30 terminals.

[0016] Preferably, the power distribution board body has two sides protruding outward from the middle position, and the first power supply interfaces of the power adjustment on both sides of the front are distributed on the protruding positions.

[0017] Preferably, the two ends of the power distribution board body are respectively provided with mounting holes for installation and fixing.

[0018] According to a second aspect of this application, a drone is proposed, including a drone power distribution board as described above.

Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0028] According to a first aspect of this application, a drone power distribution board and a drone are proposed. The specific structure of the drone power distribution board according to an embodiment of this application will be described below with reference to the accompanying drawings.

[0029] Please see Figure 1 and Figure 2 The UAV power distribution board includes a power distribution board body 1, which has a front side 101 and a back side 102. A power interface 2 is located at the center of the first end 103 of the front side 101. Several device interfaces and power supply interfaces are distributed at the first end 103, the second end 104, and both sides of the front side 101. The device interfaces are used to connect auxiliary devices, and the power supply interfaces provide power to the connected devices. A Hall element 3 is located near the power interface 2 on the back side 102. A first pad 4 and a second pad 5 are distributed along both sides of the Hall element 3 on the back side 102. The first pad 4 is electrically connected to the power interface 2, and the second pad 5 is electrically connected to several power supply interfaces. An induction coil 6 passing through the Hall element 3 connects the first pad 4 and the second pad 5.

[0030] By setting Hall element 3 on the power distribution board body 1, during the operation of the UAV, the main current output by the power interface 2 flows through the induction coil 6 and then through the Hall element 3, and is finally distributed to each power supply interface as branch current. Thus, the Hall element 3 can accurately detect the real-time power consumption of each connected auxiliary device through magnetic induction.

[0031] In one specific embodiment, several device interfaces include a gimbal camera interface 7, a 4K FPV camera interface 8, a sky terminal interface 9, and a flight control interface 10, which are distributed on one side of the front 101 of the power distribution board body 1.

[0032] It is understood that in other embodiments, several device interfaces may be distributed on one or both sides of the front of the power distribution board body, and the several device interfaces may be one or more of the following: gimbal camera interface, 4K FPV camera interface, sky terminal interface and flight control interface.

[0033] In one specific embodiment, the power supply interfaces include a first ESC power supply interface 11 distributed on both sides of the front side 101 of the power distribution board body 1, a first power supply interface 12 and a flight control power supply interface 13 at the first end 103 of the power distribution board body 1, and a second power supply interface 14 and a second ESC power supply interface 15 at the second end 104 of the power distribution board body 1. The first power supply interface 12 and the flight control power supply interface 13 are located on both sides of the power interface 2, the second ESC power supply interface 15 is located in the middle of the second end 104, and the second power supply interface 14 is located on one side of the second ESC power supply interface 15.

[0034] It is understood that in other embodiments, the power supply interfaces may be one or more of the following: a first ESC power supply interface, a first power supply interface, a flight control power supply interface, a second power supply interface, and a second ESC power supply interface.

[0035] In one specific embodiment, the first ESC power supply interface 11 serves as the rotor ESC power supply interface, providing power to the rotor ESCs on both sides of the UAV; the second ESC power supply interface 15 serves as the fixed-wing ESC power supply connector, providing power to the fixed wing (tail thrust rotor) at the tail of the UAV.

[0036] It is understood that in this embodiment, the power distribution board is applied to a 4+1 configuration vertical take-off and landing fixed-wing UAV, that is, the UAV has four rotors mounted on the two wings and one fixed wing (tail thrust rotor) mounted on the tail. In other embodiments, the power distribution board can also be applied to multi-rotor UAVs, fixed-wing UAVs, etc., and the number of ESC power supply interfaces of the power distribution board can also be set according to the number of rotors and fixed wings of the UAV, which is not limited here.

[0037] In one specific embodiment, the first power supply interface 12 and the second power supply interface 14 are electrically connected to multiple device interfaces to provide power to connected devices such as servos, gimbal cameras, 4K FPV cameras, sky terminals, and flight controllers.

[0038] In one specific embodiment, the power interface 2 and multiple power supply interfaces adopt XT series terminals. Specifically, the power interface 2 adopts XT90 terminals, the first ESC power supply interface 11 and the second ESC power supply interface 15 adopt XT60 terminals, and the first power supply interface 12 and the second power supply interface 14 adopt XT30 terminals.

[0039] In one specific embodiment, the power distribution board body 1 has two protruding points on the middle of its two sides, and the first ESC power supply interfaces 11 on both sides of the front 101 of the power distribution board body 1 are distributed on the protruding points. This protruding structure ensures that the first ESC power supply interfaces 11 will not interfere with adjacent components when wiring, and at the same time, when the power distribution board is installed on the drone body, it can be embedded and cooperate with the drone body to achieve a better installation effect.

[0040] In one specific embodiment, the first end 103 and the second end 104 of the power distributor body 1 are respectively provided with mounting holes 16 for installation and fixing. The power distributor can be installed and fixed to the drone body by tightening screws in the mounting holes 16.

[0041] In summary, the UAV power distribution board provided in this application, by setting Hall element 3 on the back 102 of the power distribution board body 1, can accurately detect the real-time power consumption of each connected auxiliary device based on the magnitude of the current flowing through the induction coil 6. The multiple device interfaces and power supply interfaces on the power distribution board body 1 are compactly arranged, further simplifying wiring. This allows the power output from the power interface 2 to supply multiple connected devices, reducing not only the size of the entire power distribution board but also its weight, thus lowering the overall weight of the UAV. The protruding structures on both sides of the power distribution board body 1 and the mounting holes 16 at both ends facilitate the fixed installation of the power distribution board with the UAV fuselage structure.

[0042] According to a second aspect of this application, a drone is also proposed, including a drone power distribution board as described in the first aspect above.
