[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0030] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0031] Please see Figure 1 and Figure 2 The power unit 1000 for the unmanned aerial vehicle (UAV) includes a motor assembly 10, an electronic speed controller (ESC) assembly 20, a clamping device 30, a base 50, and a support rod assembly 60. The motor assembly 10, ESC assembly 20, clamping device 30, and support rod assembly 60 are all mounted on the base 50, and the motor assembly 10 is electrically connected to the ESC assembly 20. The motor assembly 10 is typically used to control the rotation of the propeller on the UAV. The high-speed rotation of the motor generates sufficient lift from the propeller to overcome the weight of the UAV, enabling takeoff, hovering, and flight. The ESC assembly 20 controls the rotational speed of the motor. The support rod assembly 60, located in the clamping device 30, serves as the main support structure, connecting the motor mounting base and the UAV frame, and transmitting force and torque.

[0032] To better explain the structure of the power sleeve device 1000, it will be described in conjunction with the first direction Z, the second direction X, and the third direction Y, wherein the first direction Z is perpendicular to the second direction X and the third direction Y.

[0033] For the aforementioned clamping device 30, base 50, and support rod assembly 60, such as Figures 2-4 As shown, the base 50 is provided with a mounting cavity 50a, and the clamping device 30 is disposed in the mounting cavity 50a. The clamping device 30 is fixed relative to the base 50. The clamping device 30 includes a first pipe clamp 31 and a second pipe clamp 32, which are spaced apart from each other along a first direction. The support rod assembly 60 includes a first support rod 601 and a second support rod 602, which are disposed in the first pipe clamp 31 and the second support rod 602, and both the first support rod 601 and the second support rod 602 extend along a second direction.

[0034] In this design, when both the first pipe clamp 31 and the second pipe clamp 32 are in the first state, the first pipe clamp 31 clamps the first support rod 601, and the second pipe clamp 32 clamps the second support rod 602. When both the first pipe clamp 31 and the second pipe clamp 32 are in the second state, the first pipe clamp 31 releases the first support rod 601, and the second pipe clamp 32 releases the second support rod 602. Compared with the single carbon tube structure power sleeve in the prior art, in this application, the first pipe clamp 31 and the second pipe clamp 32 can be used to install the first support rod 601 and the second support rod 602 respectively, thereby realizing the installation of double support rods. The double support rod design can provide stronger structural support, better withstand stress under high load and complex working conditions, and is more convenient. It should be noted that: the first state refers to the state in which both the first pipe clamp 31 and the second pipe clamp 32 are clamped, and at this time, both the first support rod 601 and the second support rod 602 are locked. The second state refers to the state in which both the first pipe clamp 31 and the second pipe clamp 32 are released, and at this time, the first support rod 601 can be removed from the first pipe clamp 31 and the second support rod 602 can be removed from the second pipe clamp 32.

[0035] It is understood that the first support rod 601 and the second support rod 602 can be pipes made of carbon tubes, round tubes, square tubes or other materials, and no specific limitation is made in this application.

[0036] In some embodiments, please refer to the following: Figure 2 and Figure 4 The first pipe clamp 31 includes a first elastic arm 311 and a second elastic arm 312. One end of the first elastic arm 311 is connected to one end of the second elastic arm 312. The other end of the first elastic arm 311 and the other end of the second elastic arm 312 are spaced together to form a first tensioning groove 31a. The first elastic arm 311 and the second elastic arm 312 enclose each other to form a first mounting groove 31b. The first mounting groove 31b is connected to the first tensioning groove 31a. At least a portion of the first support rod 601 is located in the first mounting groove 31b. The first mounting groove 31b is used for mounting the first support rod 601. The size of the opening of the first tensioning groove 31a can be used to adjust the tightness of the first pipe clamp 31. When the opening of the first tensioning groove 31a becomes smaller, the first pipe clamp 31 is in a clamped state. When the opening of the first tensioning groove 31a becomes larger, the first pipe clamp 31 is in a loosened state.

[0037] In some embodiments, there are multiple first pipe clamps 31, which are arranged at intervals along the second direction. The multiple first pipe clamps 31 clamp multiple positions of the first support rod 601 along the second direction, thereby making the first support rod 601 more stably installed on the base 50.

[0038] In some embodiments, the second pipe clamp 32 includes a third elastic arm 321 and a fourth elastic arm 322. One end of the third elastic arm 321 is connected to one end of the fourth elastic arm 322. The other end of the third elastic arm 321 and the other end of the fourth elastic arm 322 are spaced apart to form a second tensioning groove 32a. The third elastic arm 321 and the fourth elastic arm 322 enclose to form a second mounting groove 32b. The second mounting groove 32b communicates with the second tensioning groove 32a. At least a portion of the second support rod 602 is located in the second mounting groove 32b. The second mounting groove 32b is used for mounting the second support rod 602. The size of the opening of the second tensioning groove 32a can be used to adjust the tightness of the second pipe clamp 32. When the opening of the second tensioning groove 32a becomes smaller, the second pipe clamp 32 is in a clamped state. When the opening of the second tensioning groove 32a becomes larger, the second pipe clamp 32 is in a loosened state.

[0039] In some embodiments, there are multiple second pipe clamps 32, which are spaced apart along the second direction and clamp multiple positions of the second support rod 602 along the second direction, thereby making the second support rod 602 more stably installed on the base 50.

[0040] In some embodiments, such as Figure 2 As shown, a first connector 313 is also provided on the base 50. The first connector 313 passes through the opening between the first elastic arm 311 and the second elastic arm 312. The first connector 313 is used to adjust the size of the opening of the first tension groove 31a. The user can tighten or loosen the first connector 313 to make the opening between the first elastic arm 311 and the second elastic arm 312 gradually smaller or larger, that is, to adjust the opening of the first tension groove 31a to make it smaller or larger. When the first connector 313 is tightened, the opening between the first elastic arm 311 and the second elastic arm 312 gradually becomes smaller, and the first pipe clamp 31 is in a clamped state. When the first connector 313 is loosened, the opening between the first elastic arm 311 and the second elastic arm 312 gradually becomes larger, and the first pipe clamp 31 is in a loosened state. Optionally, the first connector 313 is a first screw. Whether clockwise rotation of the first screw corresponds to a tightened state or a loosened state, and whether counterclockwise rotation corresponds to a tightened state or a loosened state, is not specifically limited in this application.

[0041] In some embodiments, a second connector 314 is also provided on the base 50. The second connector 314 passes through the opening between the third elastic arm 321 and the fourth elastic arm 322. The second connector 314 is used to adjust the size of the opening of the second tension groove 32a. The user can tighten or loosen the second connector 314 to make the opening between the third elastic arm 321 and the fourth elastic arm 322 gradually smaller or larger, that is, to adjust the opening of the second tension groove 32a to be smaller or larger. When the second connector 314 is tightened, the opening between the third elastic arm 321 and the fourth elastic arm 322 gradually becomes smaller, and the second pipe clamp 32 is in a clamped state. When the second connector 314 is loosened, the opening between the third elastic arm 321 and the fourth elastic arm 322 gradually becomes larger, and the second pipe clamp 32 is in a loosened state. Optionally, the second connector 314 is a second screw. Whether the clockwise rotation of the second screw corresponds to a tightened state or a loosened state, and whether the counterclockwise rotation corresponds to a tightened state or a loosened state, is not specifically limited in this application.

[0042] It should be noted that in the above embodiments, the tightness of the first pipe clamp 31 and the second pipe clamp 32 can be adjusted respectively using the first connecting member 313 and the second connecting member 314. In this case, the first connecting member 313 adjusts the tightness of the first pipe clamp 31 alone, and the second connecting member 314 adjusts the tightness of the second pipe clamp 32 alone. In some embodiments, the tightness of the first pipe clamp 31 and the second pipe clamp 32 can be adjusted simultaneously using the locking assembly 40, as described in detail below.

[0043] In some embodiments, such as Figure 5 and Figure 6 As shown, in order to facilitate simultaneous adjustment of the tightness of the first pipe clamp 31 and the second pipe clamp 32, the openings of the first loosening groove 31a and the second loosening groove 32a are arranged opposite to each other. The locking component 40 is disposed on the base 50. The locking component 40 can be used to simultaneously adjust the size of the opening of the first loosening groove 31a and the size of the opening of the second loosening groove 32a.

[0044] In some embodiments, please refer to the following: Figure 7 The base 50 is provided with a first connecting groove 50f, which passes through the opening between the first elastic arm 311 and the second elastic arm 312, and the first connecting groove 50f passes through the opening between the third elastic arm 321 and the fourth elastic arm 322. The first connecting groove 50f is connected to the first tensioning groove 31a and the second tensioning groove 32a. The first connecting groove 50f is used for the installation of the locking assembly 40.

[0045] Please refer to the following for details. Figure 8 and Figure 9The locking assembly 40 includes a connecting rod 401, a rotating rod 402, and a locking cam 403. One end of the connecting rod 401 passes through the first connecting groove 50f and extends outward. The rotating rod 402 is rotatably connected to one end of the connecting rod 401. The locking cam 403 is sleeved on the rotating rod 402 and can rotate with the rotating rod 402. When the locking cam 403 rotates to the first position, the connecting rod 401 simultaneously locks the opening of the first tension groove 31a and the opening of the second tension groove 32a. When the locking cam 403 rotates to the second position, the connecting rod 401 simultaneously releases the opening of the first tension groove 31a and the opening of the second tension groove 32a, thereby realizing the simultaneous adjustment of the size of the opening of the first tension groove 31a and the size of the opening of the second tension groove 32a.

[0046] In some embodiments, the locking assembly 40 further includes a first washer 404, which is sleeved on the connecting rod 401. One side of the first washer 404 abuts against the other end of the connecting rod 401, and the other side of the first washer 404 abuts against the first pipe clamp 31 and the second pipe clamp 32. The first washer 404 can make the force between the first pipe clamp 31, the second pipe clamp 32 and the connecting rod 401 more uniform and reduce local pressure.

[0047] In some embodiments, the locking assembly 40 further includes a second washer 405, which is sleeved on the connecting rod 401. One side of the second washer 405 abuts against the first pipe clamp 31 and the second pipe clamp 32, and the other side of the second washer 405 abuts against the locking cam 403. The second washer 405 can make the force between the first pipe clamp 31, the second pipe clamp 32 and the locking cam 403 more uniform and reduce local pressure.

[0048] In some embodiments, please refer to the following: Figure 10The locking cam 403 includes a first locking surface 403a and a second non-locking surface 403b. The distance from the first locking surface 403a to the rotation center of the rotating rod 402 is greater than the distance from the second non-locking surface 403b to the rotation center of the rotating rod 402. When it is necessary to lock the openings of the first loosening groove 31a and the second loosening groove 32a, the user only needs to rotate the locking cam 403 to the first position so that the first locking surface 403a fits against the first pipe clamp 31 and the second pipe clamp 32. At this time, the locking cam 403 cooperates with the connecting rod 401 to compress the first... The first and second tensioning grooves 31a and 32a are connected by a connecting rod 401. When the locking cam 403 rotates to the second position, the first locking surface 403a no longer adheres to the first clamp 31 and the second clamp 32. At this time, the locking cam 403 and the connecting rod 401 no longer press against the openings of the first and second tensioning grooves 31a and 32a, and the connecting rod 401 simultaneously releases the openings of the first and second tensioning grooves 31a and 32a. It can be understood that the first locking surface 403a is, but is not limited to, an arc surface or a flat surface, and the second non-locking surface 403b is, but is not limited to, an arc surface or a flat surface.

[0049] In some embodiments, please refer to the following: Figure 4 The base 50 is also provided with a first inclined opening 50b and a second inclined opening 50c that connects to the mounting cavity 50a. The first pipe clamp 31 and the second pipe clamp 32 are both located in the mounting cavity 50a. The first connector 313 is located at the first inclined opening 50b, and the second connector 314 is located at the second inclined opening 50c. The first inclined opening 50b facilitates the installation of the first connector 313 and provides clearance for its installation. The second inclined opening 50c facilitates the installation of the second connector 314 and provides clearance for its installation.

[0050] In some embodiments, the base 50 is further provided with a first mounting port 50d1 and a second mounting port 50d2 communicating with the mounting cavity 50a, and the first mounting port 50d1 and the second mounting port 50d2 are arranged opposite each other along a third direction. The first mounting port 50d1 and the second mounting port 50d2 are used for mounting the power supply adjustment component 20.

[0051] In some embodiments, the base 50 is also provided with a cable through hole 50e communicating with the mounting cavity 50a. The cable through hole 50e facilitates the cable in the motor assembly 10 to extend into the mounting cavity 50a and connect to the ESC assembly 20.

[0052] In some embodiments, a first mounting surface 51 and a second mounting surface 52 are provided on the base 50. The first mounting surface 51 and the second mounting surface 52 are spaced apart along a first direction. The first mounting surface 51 and the second mounting surface 52 are used for mounting the power supply assembly 10.

[0053] For the aforementioned motor assembly 10, such as Figure 2 As shown, the motor assembly 10 is detachably connected to the outer surface of the base 50, and the motor assembly 10 is connected to the electronic speed controller assembly 20. The motor assembly 10 includes a first motor 101 and a second motor 102, which are symmetrically mounted on the base 50. The first motor 101 is detachably connected to the first mounting surface 51 of the base 50 via a first adapter 1011, and the second motor 102 is detachably connected to the second mounting surface 52 of the base 50 via a second adapter 1021.

[0054] For the aforementioned ESC component 20, such as Figure 2 As shown, the electronic speed controller (ESC) assembly 20 is detachably connected to the outer surface of the base 50. The ESC assembly 20 includes a first speed controller 201 and a second speed controller 202, which are symmetrically mounted on the base 50. The first speed controller 201 covers the first mounting opening 50d1 and is detachably connected to the base 50. The second speed controller covers the second mounting opening 50d2 and is detachably connected to the base 50. The first speed controller 201 is connected to the first motor 101, and the second speed controller 202 is connected to the second motor 102. It is understood that the detachable connection methods between the first speed controller 201 and the base 50, and between the second speed controller 202 and the base 50, include, but are not limited to, screw connections, threaded connections, riveted connections, snap-fit ​​connections, etc.

[0055] In this embodiment, a base 50, a clamping device 30, a support rod assembly 60, an electronic speed control assembly 20, and a motor assembly 10 are provided. The base 50 has a mounting cavity 50a, and the clamping device 30 is disposed within the mounting cavity 50a, fixed relative to the base 50. The clamping device 30 includes a first pipe clamp 31 and a second pipe clamp 32, which are spaced apart from each other along a first direction.

The first support rod 601 is disposed within the first pipe clamp 31, and the second support rod 602 is disposed within the second pipe clamp 32. Both the first and second support rods extend along a second direction, which is perpendicular to the first direction. The electronic speed control assembly 20 is detachably connected to the outer surface of the base 50, and the motor assembly 10 is detachably connected to the base 50. On the outer surface of 0, the motor assembly 10 is connected to the electronic speed control assembly 20. When both the first pipe clamp 31 and the second pipe clamp 32 are in the first state, the first pipe clamp 31 clamps the first support rod 601, and the second pipe clamp 32 clamps the second support rod 602. When both the first pipe clamp 31 and the second pipe clamp 32 are in the second state, the first pipe clamp 31 releases the first support rod 601, and the second pipe clamp 32 releases the second support rod 602.
