Different wiring of the motor 400 may affect the direction of rotation of the motor 400. In an embodiment, different motors 400 may require different rotational directions to rotate in order to allow the unmanned aerial vehicle 100 to fly smoothly as a whole, for example, adjacent motors 400 rotate in opposite directions so that the torques applied to the fuselage 200 by the plurality of motors 400 and the propeller 700 cancel each other out. Therefore, the steering of the motor 400 is important for smooth flight of the unmanned aerial vehicle 100, and the steering of the motor 400 can be set correspondingly through different connection modes of the motor 400 and the three-phase line 810.

The first surface 611d and the second surface 611e are two opposite surfaces of the first shell 611, wherein the first surface 611d is disposed toward the receiving space 613.

Specifically, the first through hole 611a and the second through hole 611b penetrate the first surface 611d and the second surface 611e, and are communicated with the receiving space 613. The first through hole 611a is used for the first fastener 641 to pass through to electrically connect the first connector 630 and the circuit board 620. The second through hole 611b is used for the second fastening element 642 to pass through so as to electrically connect the circuit board 620 and the first conductive assembly 671.

The electro-tilt mount 500 has a fitting portion 510 and a groove 520 thereon so that the electron governor 600 can be mounted on the horn 300 through the electro-tilt mount 500.

In this embodiment, referring to fig. 4 to 8 and fig. 10, a mounting portion 612a is disposed on the second housing 612, and the mounting portion 612a is detachably connected to the mounting portion 510, so as to mount the electronic governor 600 outside the machine arm 300. In some embodiments, the mounting portion 612a is a mounting hole, the mounting portion 510 is a mounting hole, and a fastener such as a screw is inserted through the mounting portion 612a and the mounting portion 510 to fix the second housing 612 and the electric tuning mount 500, and the horn 300 is sandwiched between the second housing 612 and the electric tuning mount 500, thereby fixing the electronic governor 600 to the outside of the horn 300. It can be understood that, in other embodiments, any suitable connection manner may be selected for the mounting portion 612a and the assembling portion 510 according to actual requirements, for example, the mounting portion 612a is designed as a snap groove, and the assembling portion 510 is designed as a snap, or the mounting portion 612a is designed as a snap groove, and the mounting portion 612a and the assembling portion 510 are combined by means of a snap, and the like, as long as the second housing 612 and the electrically tunable mounting base 500 can be detachably connected.

In the above embodiment, when the electronic governor 600 has a fault, the electronic governor 600 can be disassembled without detaching and taking out the electronic governor 600 from the inside of the machine arm, so that the electronic governor 600 can be quickly repaired and/or replaced, and the operability and efficiency of the repair can be improved.

Referring to fig. 10 and 13, a fitting portion 612b is disposed on a side of the second housing 612 away from the accommodating space 613, so as to form a penetrating portion for the horn 300 to penetrate through in cooperation with the electrical tuning mounting base 500. In this embodiment, the fitting portion 612b is an arc-shaped concave portion, the groove 520 is an arc-shaped groove, and the penetrating portion is a closed annular through hole structure.

In the above embodiment, when the electronic governor 600 fails and needs to be overhauled, since the electronic governor 600 is mounted outside the horn 300, the first housing 611 and the second housing 612 are detachably connected, and the circuit board 620 is accommodated in the accommodating space 613 formed by the first housing 611 and the second housing 612, the first housing 611 and the second housing 612 can be directly disassembled without detaching the electronic governor 600 from the inside of the horn 300 and taking out the electronic governor or first detaching the electronic governor 600 from the electrically tunable mounting base 500, so that components inside the electronic governor 600, such as the circuit board 620, can be overhauled and/or replaced quickly, and the operability and efficiency of overhaul are improved.

The electronic governor 600 generates a large amount of heat during operation. In a preferred embodiment, in order to improve the heat dissipation efficiency of the circuit board, the first shell 611 and the second shell 612 may be made of metal such as copper, copper alloy, aluminum alloy, or the like, or conductive material such as conductive plastic, conductive rubber, or the like. In this embodiment, the first shell 611 and the second shell 612 are both made of metal, such as aluminum alloy.

Referring to fig. 4 to 8, the circuit board 620 is mounted in the receiving space 613. Specifically, the circuit board 620 may be carried on the second housing 612. The circuit board 620 may be populated with control circuitry and integrated with electronic components such as capacitors, inductors, diodes, etc. Circuit board 620 can be electrically connected to motor 400, flight control system 830, and power supply 820.

The circuit board 620 is provided with a first conductive pillar 621 and a second conductive pillar 622. The first conductive pillar 621 is connected to the first fastening member 641 to electrically connect the circuit board 620 and the first connector 630. The second conductive post 622 is connected to the second fastener 642 to electrically connect the circuit board 620 and the first conductive assembly 671. In the present embodiment, the structure of the second conductive pillars 622 is the same as that of the first conductive pillars 624. For convenience of description, the first conductive pillar 621 is taken as an example for description.

Referring to fig. 4 to 8, the first conductive pillar 621 includes a hollow portion 621a, a transition portion 621b, and a base portion 621 c. Wherein the hollow portion 621a has a fixing hole 621d adapted to the first fastening member 641. One end of the transition portion 621b is connected to the hollow portion 621a, and the other end of the transition portion 621b is connected to the base portion 621 c. In some embodiments, the transition portion 621b has a larger profile than the hollow portions 621a and the base portion 621c to save raw materials. One end of the base portion 621c is connected to the hollow portion 621a, and the other end of the base portion 621c is electrically connected to the circuit board 620. It is understood that in other embodiments, the transition portion 621b may be omitted and the hollow portion 621a is directly connected to the base portion 621 c.

Referring to fig. 4 to 12, a first connector 630 is used to electrically connect the motor 400 and the electronic governor 600. Specifically, the first connector 630 includes a first conductive member 631 and a first package member 632. First conductive member 631 is electrically connected to one end of three-phase line 810. The first conductive member 631 may be made of a conductive material such as copper, a copper alloy, an aluminum alloy, a conductive plastic, a conductive rubber, or the like. The first conductive member 631 is encapsulated in the first encapsulation member 632, and the first conductive member 631 is at least partially exposed from the first encapsulation member 632.

The first conductive member 631 includes a conductive ring and a connector portion. The conductive ring is fixedly connected with the joint part. In this embodiment, the conductive ring and the joint portion are integrally formed. It is understood that in other embodiments, the conductive ring and the joint portion may be separate components, and in this case, the conductive ring and the joint portion may be fixed by welding or the like.

The conductive ring has a first through hole 631c for the first fastener 641 to pass through. For example, when the first fastening member 641 is a screw, the stud of the first fastening member 641 may pass through the first through hole 631c and be electrically connected to the circuit board 620, and the nut of the first fastening member 641 may be abutted against a side of the conductive ring departing from the circuit board 620 to be electrically connected to the conductive ring. The connector portion is used to electrically connect the conductive ring and the three-phase line 810.

The first package member 632 is used to package the first conductive member 631, and the first package member 632 may also package a portion of the three-phase line 810. In the process of manufacturing the first package 632, the connected three-phase lines 810 and the first conductive elements 631 may be fixed together in an injection mold, and the first package 632 may be obtained by injection molding through processes such as encapsulation molding and the like. The first package 632 may be made of an insulating material, for example, the material of the first package 632 may be plastic. The overall shape of the first package 632 may be square, circular, trapezoidal, etc., without limitation. The first enclosure 632 may be disposed on the first housing 611 when the motor 400 is connected to the circuit board 620.

The first package 632 has a third surface 632a, a fourth surface 632b and a first connection portion 632c that are opposite to each other. In the present embodiment, the first connection portion 632c passes through the third surface 632a and the fourth surface 632b, and the fourth surface 632b is disposed toward the first case 611. The first connection portion 632c includes a first opening portion 632d and a second opening portion 632e that are electrically connected to each other. The conductive ring is disposed at the connection position of the first opening portion 632d and the second opening portion 632e, and both the first opening portion 632d and the second opening portion 632e are communicated with the first through hole 631 c. The fourth face 632b of the first enclosure 632 may be coupled with the second face 611e of the first housing 611 when the first connector 630 is mounted. Specifically, the fourth surface 632b of the first package 632 may be abutted against the second surface 611e of the first shell 611. The first fastener 641 penetrates the first opening portion 632d, the first through hole 631c, the second opening portion 632e and the first through hole 611a to electrically connect the first conductive member 631 and the circuit board 620.

As a preferred embodiment, at least a portion of the first conductive member 631 may be exposed from the first connection portion 632c to allow the first fastening member 641 to be mounted on the first connection portion 632c and electrically connect the first conductive member 631 and the circuit board 620. Specifically, the conductive loop may be exposed from the first opening 632 d. The first opening 632d may be formed on the third surface 632a, and the second opening 632e may be formed on the fourth surface 632 b. The cross-sectional dimension of the first opening portion 632d is larger than the cross-sectional dimension of the second opening portion 632e, and the cross-sectional dimension of the first opening portion 632d is matched with the maximum cross-sectional dimension of the first fastening member 641. When the first fastening member 641 is a screw, the first opening portion 632d is sized to just receive the head of the screw, and the second opening portion 632e cannot provide a receiving space for the head of the screw. Therefore, when the user needs to mount the first connector 630, the user can fixedly connect the first connector 630 and the first shell 611 by the first fastening member 641 only when the first connector 630 is in a state where the fourth surface 632b is coupled to the second surface 611e of the first shell 611 and the first opening portion on the third surface 632a is exposed. Therefore, the first connector 630 ensures that the motor 400 is connected with the electronic governor 600 in a predetermined connection manner, and prevents a user from reversely mounting the first connector 630.

In this embodiment, the first fastening member 641 is a screw. In some embodiments, after the first fastening member 641 is mounted in place, the head of the first fastening member 641 can be completely received in the first opening 632d without protruding from the third surface 632a, and the user can further determine whether the first fastening member 641 protrudes from the third surface 632a and is mounted correctly. It is understood that in other embodiments, the head of the first fastening member 641 may be partially received in the first opening 632d, as long as the first fastening member 641 can electrically connect the first conductive member 631 to the circuit board 620. In other embodiments, the first fastening member 641 may have any other suitable structure as long as the first fastening member 641 can electrically connect the first conductive member 631 with the circuit board 620 and fasten the first connector 630, the first housing 611, and the circuit board 620.

Since the first conductive member 631 is electrically connected to the three-phase line 810, and the other end of the three-phase line 810 is electrically connected to the motor 400, when the motor is installed, a user only needs to conduct the exposed first conductive member 631 to the circuit board 620 through the conductive first fastening member 641, so as to electrically connect the motor 400 and the electronic speed regulator 600.

In some embodiments, the number of the first conductive members 631 is plural, and the number of the first connection portions 632c is plural, and each of the first conductive members 631 is exposed from a corresponding one of the first connection portions 632 c. In this embodiment, the number of the first conductive members 631 is three, each first conductive member 631 is connected to one of the three-phase lines 810, the plurality of first conductive members 631 are packaged together in the same first package 632, and the three-phase lines 810 are not scattered, so that the structure is compact. The number of the first connection portions 632c is multiple, each first conductive member 631 is exposed from a corresponding one of the first connection portions 632c, and a plurality of first fastening members 641 may be disposed, wherein each first fastening member 641 passes through one of the first connection portions 632c and the first conductive member 631 to electrically connect the circuit board 620 and the first connector 630. The number of the first through holes 611a may also be plural, and each of the first through holes 611a is aligned with one of the first connection portions 632 c. Of course, the number of the first conductive members 631 is not limited to three, and may be set differently according to different requirements, for example, the number of the first conductive members 631 is one, two, four, five, six or more.

Referring to fig. 4 to 12, the first conductive element 671 and the second conductive element 672 are disposed outside the first shell 611. First conductive element 671 is adapted for electrical connection with power source 820 and second conductive element 672 is adapted for electrical connection with flight control system 830.

The first conductive assembly 671 includes a second conductive member 671a and a second package 671 b. The second conductive member 671a has a second through hole 671c electrically connected to the power source 820 through a conductive wire. The second package 671b has a fifth surface 671d, a sixth surface 671e, and a second connection portion 671 f. The second conductive member 671a is encapsulated in the second encapsulation 671 b. The second connection portion 671f penetrates the fifth surface 671d and the sixth surface 671e, and communicates with the second penetration hole 671 c. When the first conductive member 671 is mounted, the sixth surface 671e of the second package 671b may be combined with the second surface 611e of the first case 611. Specifically, the sixth surface 671e of the second package 671b may abut against the second surface of the first housing. The second fastening member 642 penetrates the second connecting portion 671f, the second through hole 671c and the second through hole 611b to electrically connect the second conductive member 671a and the circuit board 620.

In a preferred embodiment, the second conductive member 671a may be at least partially exposed from the second connection portion 671f to allow the second fastening member 642 to be mounted on the second connection portion 671f and electrically connect the first conductive member and the circuit board 620. The cross-sectional dimension of the second connection portion 671f near the fifth surface 671d is larger than that of the second connection portion 671f near the sixth surface 671 e. The cross-sectional dimension of the second connecting portion 671f near the fifth surface 671d is adapted to the dimension of the second fastening member 642. When the second fastening member 642 is a screw, the portion of the second connecting portion 671f near the fifth surface 671d can just receive the head of the screw, and the portion of the second connecting portion 671f near the sixth surface 671e cannot provide a receiving space for the head of the screw. Therefore, when the user needs to mount the first conductive assembly 671, the user can fixedly connect the first conductive assembly 671 and the first housing via the second fastening member 642 only when the first conductive assembly 671 is in a state that the sixth surface 671e is combined with the second surface of the first housing and the fifth surface 671d is exposed. Therefore, the first conductive assembly 671 ensures that the motor is connected with the electronic governor 600 in a predetermined connection manner, and prevents a user from reversely mounting the first conductive assembly 671.

In this embodiment, the second fastening member 642 is a screw, and after the second fastening member 642 is mounted in place, the head of the second fastening member 642 can be completely accommodated in the second connecting portion 671f without protruding from the fifth surface 671d, and the user can further determine whether the second fastening member 642 protrudes from the fifth surface 671d to determine whether the second fastening member is mounted correctly and in place. It is understood that, in other embodiments, the head of the second fastening member 642 may be partially received in the second opening 632e, as long as the second fastening member 642 can electrically connect the second conductive member 671a to the circuit board 620.

Since the second conductive member 671a is electrically connected to the power source 820 through a wire. Specifically, the second conductive member 671a is electrically connected to one end of a wire, and the other end of the wire is electrically connected to the power supply 820, so that when the electronic speed regulator 600 is installed, the user only needs to conduct the exposed second conductive member 671a to the circuit board 620 through the conductive second fastening member 642, and the purpose of electrically connecting the power supply and the electronic speed regulator 600 can be achieved.

In some embodiments, the number of the first conductive members 671 is two, each of the second packages 671b is provided with a second connection portion 671f, each of the second conductive members 671a is exposed from the corresponding first connection portion 632c, one of the second conductive members 671a is connected to the positive electrode of the power source 820, and the other second conductive member 671a is connected to the negative electrode of the power source 820. It is understood that, in other embodiments, the first conductive assembly 671 may be designed into any other suitable structure according to different requirements, for example, two second connection portions 671f are disposed on the second package 671b, and two second conductive members 671a are disposed on the same second package 671b, as long as the first conductive assembly 671 can electrically connect the power source 820 and the circuit board 620.

The second conductive assembly 672 has a first electrical connection portion 672a, the circuit board 620 is provided with a second electrical connection portion 623, and the first electrical connection portion 672a penetrates through the socket portion 611c to be electrically connected with the second electrical connection portion 623. The first electrical connection 672a may be at least one of a metal male, a metal female, or a metal contact. The second electrical connection portion 623 is at least one of a metal female connector, a metal male connector, a metal contact, or the like, which is engaged with the first electrical connection portion 672 a.

The first fastening member 641 and the second fastening member 642 may be made of a conductive material such as copper, copper alloy, aluminum alloy, conductive plastic, conductive rubber, or the like.

In order to prevent rainwater or substances such as sprayed liquid during operation of the unmanned aerial vehicle from entering the accommodating space along the first through hole to damage the circuit board 620, the working reliability of the electronic speed regulator is ensured, and a first waterproof assembly 650 is further sleeved outside the first fastening piece 641 to seal a gap at the joint of the first shell 611 and the first fastening piece 641. Specifically, first flashing assembly 650 includes a first flashing 651 and a second flashing 652.

The first waterproof member 651 is provided on the first surface 611d of the first housing 611, and prevents water from flowing into the accommodating space from the first through hole 611 a. Specifically, the first waterproof member 651 includes a body 651a and a first hole structure 651 b. The two opposite sides of the main body 651a respectively abut against the first surface 611d of the first shell 611 and the transition portion 621b of the first conductive post 621. The first hole structure 651b is used for the hollow portion 621a of the first conductive post 621 to pass through, and has a hollow boss 651c protruding from the body 651 a. The outside of the hollow boss 651c abuts against the first through hole 611a and is in interference fit with the first through hole 611a, when the first fastener 641 assembles the first connector 630, the first housing 611, and the first conductive post 621 in place, the hollow portion 621a of the first housing 611 and/or the first conductive post 621 presses the hollow boss 651, so as to prevent water from entering the accommodating space 613 through the first through hole 611a and through a gap at a connection between the first conductive post 621 and the first through hole 611a, thereby improving the waterproof performance of the electronic speed regulator 600.

It can be understood that the shape of the first hole structure 651b can be designed into any suitable shape according to actual requirements, for example, a circular hole structure, a square hole structure, an elliptical hole structure, etc., as long as the first fastening member 641 can be inserted. In the present embodiment, the first hole structure 651b is a circular hole structure.

In certain embodiments, the first waterproof member 651 may further include a convex portion 651 d. A convex portion 651d is provided on a side of the body 651a facing away from the second housing 612. The convex portion 651d is an annular structure, which is provided at a distance from the first hole structure 651b in the radial direction of the first hole structure 651 b. The convex portion 651d is interference-fitted with the first face 611d of the first housing 611. When the first fastener 641 assembles the first connector 630, the first housing 611, and the first conductive post 621 in place, the first housing 611 and/or the transition portion 621b of the first conductive post 621 presses the protrusion 651d, so that even if water flows from the gap between the first through hole 611a and the hollow portion of the first conductive post 621 to the first surface 611d of the first housing 611, the protrusion 651d can prevent the water from further entering the receiving space 613, thereby performing a secondary waterproof function, and further improving the waterproof performance of the electronic governor 600. It is understood that in other embodiments, the convex portion 651d may be omitted.

In the present embodiment, the number of the first hole structures 651b is three, and one convex portion 651d is provided corresponding to each first hole structure 651 b. It is understood that in other embodiments, the number of the first hole structures 651b and the first hole structures 651b can be set according to different requirements, for example, one, two or more.

The second waterproof member 652 is provided on the second surface 611e of the first housing 611, and is configured to seal a connection between the first housing 611 and the first connector 630, so as to prevent water from flowing into the accommodating space 613 from the first through hole 611a, and further improve the waterproof effect of the electronic governor 600. In this embodiment, the fourth surface 632b of the first enclosure 632 is provided with an installation groove 632f, the second waterproof member 652 has a second hole structure 652a for the first connection portion 632c to pass through, and the second waterproof member 652 is used to prevent water from entering the first through hole 611 a. Specifically, one side of the first through hole 611a facing the second surface 611e has a step surface 611h, one end of the first connecting portion facing the fourth surface 632b abuts against the step surface 611h, and two opposite sides of the second waterproof member 652 respectively abut against one end of the first through hole 611a facing the second surface 611e and the bottom wall of the mounting groove 632 f. The number of the second hole structures 652a may be one, two, three or more according to different requirements. When the number of the second hole structures 652a is two or more, the connecting ribs 652b are connected between the adjacent second hole structures 652a, and the outer contour size of the second hole structures 652a is larger than the contour size of the connecting ribs 652 b.

The first waterproof member 651 and the second waterproof member 652 are each a waterproof elastic member, such as an elastic member made of rubber or the like. When the first fastener 641 assembles the first connector 630, the first housing, and the first conductive post in place, the first housing and/or the first connector 630 may press the first waterproof member 651 and/or the second waterproof member 652, so that the first waterproof member 651 and/or the second waterproof member 652 is elastically deformed, thereby playing a role in waterproofing, and improving the waterproofing performance of the electronic governor 600.

Similarly, the second protective cover 682 can be installed according to different requirements, and is not described herein again.

Referring to fig. 4-8, in some embodiments, electronic governor 600 further includes a protective cover 687. Specifically, the protection cover 687 is connected to the second surface 611e of the first housing 611 and covers the first protection cover 681 and the first connector 630 to prevent water from entering the first connection portion of the first package 632, thereby further improving the waterproof performance. The protective cover 687 and the first shell 611 can be connected by connecting pieces such as screws, buckles, glue and the like according to different requirements.

When the electronic governor 600 is assembled, the circuit board 620 is placed on the second housing 612.

The first connector 630 is placed on the second surface 611e of the first housing 611 such that the second waterproof member 652 is seated on the mounting groove 632 f. The first fastener 6412 is inserted into the first connection portion 632c, the first through hole 631c, and the first through hole 611a to connect with the first conductive pillar 621, so as to electrically connect the first conductive member 631 and the circuit board 620.
