Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and more particularly to a drive device and a UAV. Background Technology

[0002] Drones are typically equipped with landing gear to support the entire aircraft. Related technologies incorporate drive and detection components to adjust the landing gear's position. For example, the drive and detection components work together to adjust the landing gear to a retracted position, ensuring it remains outside the fisheye lens's field of view during panoramic photography. Alternatively, the drive and detection components may work together to adjust the landing gear to an extended position, ensuring a smooth landing for the drone.

[0003] The drive and detection components are typically electrically connected to the circuit board; however, the current distribution of drive and detection components is unreasonable, resulting in a large circuit board size. Utility Model Content

[0004] The embodiments of this application propose a drive device and a drone to improve the above-mentioned technical problems.

[0005] The embodiments of this application achieve the above objectives through the following technical solutions.

[0006] An embodiment of this application provides a drive device applicable to the landing gear of a drone. The drive device includes a circuit board, a drive component, and a detection component. The drive component is disposed on the circuit board and is used to drive the landing gear of the drone to switch between different positions. The drive component has a first electrical connection portion. The detection component is disposed on the circuit board and is used to detect the position information of the landing gear. The detection component has a second electrical connection portion, wherein the first electrical connection portion and the second electrical connection portion are disposed on the same side of the circuit board.

[0007] In some embodiments, the housing of the detection component is mounted on the drive component, or the detection component is integrated into the drive component.

[0008] In some embodiments, the detection component is partially embedded within the driving component.

[0009] In some embodiments, both the second electrical connection portion and the first electrical connection portion are located at least partially on the outside of the drive assembly.

[0010] In some embodiments, the second electrical connection portion and the first electrical connection portion are both located on the side of the drive assembly away from the bottom of the housing.

[0011] In some embodiments, the circuit board includes a first board body and a second board body, the first board body being electrically connected to a first electrical connection portion, one end of the second board body being electrically connected to the first board body, and the other end of the second board body being electrically connected to the second electrical connection portion.

[0012] In some embodiments, the first electrical connection portion includes a plurality of conductive posts, which are distributed along the length direction of the first plate and also along the width direction of the first plate, and are electrically connected to the first plate.

[0013] In some embodiments, the second electrical connection portion includes a plurality of pins distributed along the length of the second board and electrically connected to the second board.

[0014] In some embodiments, the drive assembly includes a power output shaft, a drive motor, and a reducer. The driving force output by the power output shaft is used to drive the landing gear to switch between different positions. The reducer is connected between the output end of the drive motor and the power output shaft. The electrical connection part of the drive motor serves as the first electrical connection part.

[0015] In some embodiments, the drive motor and the detection component are located on opposite sides of the power output shaft in the radial direction.

[0016] The embodiments of this application provide a drone, which includes a fuselage, landing gear, and a drive device according to any of the above embodiments. The drive device is mounted on the fuselage, and the landing gear is mounted on the drive assembly.

[0017] In some embodiments, the drive unit is mounted on the bottom of the housing, and both the second electrical connection portion and the first electrical connection portion are located on the side of the drive unit away from the bottom of the housing.

[0018] In some embodiments, there are multiple landing gears, including a first landing gear and a second landing gear. The drive assembly includes a first output shaft and a second output shaft arranged coaxially. The first landing gear is mounted on the first output shaft, and the second landing gear is mounted on the second output shaft. The driving force output by the first output shaft is used to drive the first landing gear to rotate to switch between different positions, and the driving force output by the second output shaft is used to drive the second landing gear to rotate to switch between different positions. The detection assembly is used to detect the rotation angle of the first output shaft or the second output shaft.

[0019] In any of the embodiments described above, the drive component is mounted on the circuit board to drive the landing gear of the drone to switch between different positions. The detection component is also mounted on the circuit board to detect the landing gear's position information. The second electrical connection portion of the detection component and the first electrical connection portion of the drive component are located on the same side of the circuit board. This helps avoid the situation where the second and first electrical connection portions are located on different sides of the circuit board, resulting in an excessively large circuit board size. It helps reduce the size and complexity of the circuit board, optimizes the internal spatial layout of the drone, improves the neatness of the internal wiring, and leaves more space for other structures. It also helps shorten the signal transmission path length, reduces the possibility of signal interference, and improves the stability and reliability of signal transmission. Furthermore, the smaller circuit board size helps simplify the assembly process, reduce maintenance difficulty, facilitates the quick location and resolution of potential electrical connection problems, and shortens maintenance time.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0029] See Figure 1 and Figure 2 The embodiments of this application provide a drone 100, which can be an aerial photography drone, such as a panoramic aerial photography drone.

[0030] In some embodiments, the drone 100 may include a fuselage 10 and a fisheye lens, and the number of fisheye lenses may be at least one.

[0031] For example, if the drone 100 includes a fisheye lens, the fisheye lens 21 may be located at the top of the fuselage 10, or the fisheye lens 22 may be located at the bottom 12 of the fuselage 10, or the fisheye lens may be located at the head of the fuselage 10, or the fisheye lens may be located at the tail of the fuselage 10.

[0032] For example, if the drone 100 includes at least two fisheye lenses, the at least two fisheye lenses can be located in different parts of the fuselage 10, such as a fisheye lens 21 located at the top of the fuselage 10 and a fisheye lens 22 located at the bottom 12 of the fuselage 10.

[0033] The top of the fuselage 10 can refer to the part of the fuselage 10 that is away from the ground, tabletop, or other horizontal surface when the drone 100 has landed and come to a stable stop on the ground, tabletop, or other horizontal surface. The bottom 12 of the fuselage 10 can refer to the part of the fuselage 10 that faces the ground, tabletop, or other horizontal surface when the drone 100 has landed and come to a stable stop on the ground, tabletop, or other horizontal surface.

[0034] See Figures 2 to 4 In some embodiments, the drone 100 may include a drive unit 101 and landing gear 40. The drive unit 101 is mounted on the fuselage 10, for example, the drive unit 101 may be mounted on the bottom of the fuselage 10. The drive unit 101 can be used to drive the landing gear 40 to switch between different positions.

[0035] In some embodiments, the drive unit 101 can be directly fixed to the fuselage 10 by fastening structures such as screws and bolts. Alternatively, the drive unit 101 can be connected to the fuselage 10 by shock-absorbing structures, elastic structures, etc., so that the shock-absorbing structures, elastic structures, etc. can provide shock absorption for the drive unit 101, and can also absorb the dimensional deviations of parts, differences in machining accuracy, and errors accumulated during assembly, so as to facilitate the assembly of the drive unit 101 with the landing gear 40.

[0036] In some embodiments, the landing gear 40 is mounted on a drive unit 101, and the driving force output by the drive unit 101 is used to rotate the landing gear 40 to switch between different positions. For example Figure 3 As shown, the driving force output by the drive unit 101 is used to rotate the landing gear 40 relative to the fuselage 10 to a supported position. For example... Figure 4 As shown, the driving force output by the drive unit 101 is used to rotate the landing gear 40 relative to the fuselage 10 to the retracted position.

[0037] The landing gear 40 exhibits different attitudes depending on its position, such as the supported position or the retracted position. For example, the landing gear 40 may include a connecting end 411 and a supporting end 412, which may be located at opposite ends of the landing gear 40. The connecting end 411 is connected to the drive unit 101. When the landing gear 40 is in the supported position, the distance between the supporting end 412 and the fuselage 10 is greater than the distance between the supporting end 412 and the fuselage 10 when the landing gear 40 is in the retracted position. When the landing gear 40 is in the supported position, the supporting end 412 is located below the connecting end 411, so that when the UAV 100 lands and touches the ground, the supporting end 412 of the landing gear 40 can serve as the contact point with the ground.

[0038] In some embodiments, the support end 412 of the landing gear 40 in the supported position is located below the connecting end 411. This can mean that when the drone 100 lands and comes to a stop on the ground, tabletop, or other horizontal surface, the distance between the support end 412 of the landing gear 40 in the supported position and the ground, tabletop, or other horizontal surface is less than the distance between the connecting end 411 and the ground, tabletop, or other horizontal surface.

[0039] In some embodiments, the landing gear 40 can be fixed to the drive unit 101 by fastening structures such as screws and bolts. For example, the connecting end 411 can be fixed to the drive unit 101 by fastening structures such as screws and bolts.

[0040] See Figure 5 and Figure 6 In some embodiments, the drive unit 101 may include a drive assembly 30, a detection assembly 50, and a circuit board 60. The landing gear 40 may be mounted on the drive assembly 30.

[0041] A drive assembly 30 is mounted on the circuit board 60 and is used to switch the landing gear 40 between different positions. A detection assembly 50 is also mounted on the circuit board 60 and is used to detect the position information of the landing gear 40. This position information may include whether the landing gear 40 is in a supported position, a retracted position, etc.

[0042] The drive assembly 30 has a first electrical connection portion 32, and the detection assembly 50 has a second electrical connection portion 51. The second electrical connection portion 51 and the first electrical connection portion 32 are disposed on the same side of the circuit board 60, so the circuit board 60 can receive the detection data of the detection assembly 50 and control the drive assembly 30 according to the detection data.

[0043] For example, the angle corresponding to the landing gear 40 being in the retracted position is set to 0 degrees, and the angle corresponding to the landing gear 40 being in the supported position is set to 120 degrees. During the process of the circuit board 60 controlling the drive assembly 30 to rotate the landing gear 40 from the retracted position to the supported position, when the detection assembly 50 detects that the landing gear 40 has rotated to 120 degrees, it indicates that the landing gear 40 is in the supported position. At this time, the circuit board 60 can receive the detection data from the detection assembly 50 and control the drive assembly 30 to stop rotating the landing gear 40. During the process of the circuit board 60 controlling the drive assembly 30 to rotate the landing gear 40 from the supported position to the retracted position, when the detection assembly 50 detects that the landing gear 40 has rotated back to 0 degrees, it indicates that the landing gear 40 is in the retracted position. At this time, the circuit board 60 can receive the detection data from the detection assembly 50 and control the drive assembly 30 to stop rotating the landing gear 40.

[0044] Furthermore, since the second electrical connection portion 51 and the first electrical connection portion 32 are located on the same side of the circuit board 60, it helps to avoid the situation where the second electrical connection portion 51 and the first electrical connection portion 32 are located on different sides of the circuit board 60, which would result in the circuit board 60 being too large. This helps to reduce the size and complexity of the circuit board 60, optimize the internal spatial layout of the drone 100, improve the neatness of the internal wiring of the drone 100, and also leave more space for other structures. It also helps to shorten the length of the signal transmission path, reduce the possibility of signal interference, and improve the stability and reliability of signal transmission.

[0045] In addition, the smaller circuit board size (60) helps simplify the assembly process, reduce maintenance difficulty, facilitates the quick location and resolution of potential electrical connection problems, and shortens maintenance time.

[0046] In some embodiments, circuit board 60 may be a rigid circuit board, a flexible circuit board, or a rigid-flex circuit board.

[0047] In some embodiments, the first electrical connection portion 32 is disposed on the circuit board 60. For example, the first electrical connection portion 32 may be soldered to the circuit board 60, or the first electrical connection portion 32 may be pressed onto the circuit board 60 by a fixing structure. The second electrical connection portion 51 is disposed on the circuit board 60. For example, the second electrical connection portion 51 may be soldered to the circuit board 60, or the second electrical connection portion 51 may be pressed onto the circuit board 60 by a fixing structure.

[0048] In some embodiments, the first electrical connection portion 32 may include a conductive post 320 electrically connected to the circuit board 60, which helps the first electrical connection portion 3232 to carry higher current.

[0049] In some embodiments, the second electrical connection portion 51 may include a pin 510, which is electrically connected to the circuit board 60. The pin 510 is small in size, which helps to reduce the space occupied by the second electrical connection portion 51.

[0050] In some embodiments, the housing 52 of the detection component 50 can be mounted on the drive component 30, or the detection component 50 can be integrated into the drive component 30. This helps to combine the detection component 50 and the drive component 30 into a separate module, which helps to reduce the connection distance between the two, making the overall structure more compact, optimizing the internal space layout of the UAV 100, and also facilitates the rapid assembly of the module formed by combining the detection component 50 and the drive component 30 onto the fuselage 10, which helps to simplify the assembly process, reduce additional fixing and connection steps, and reduce assembly difficulty.

[0051] In some embodiments, the housing 52 of the detection component 50 can be assembled to the drive component 30 by fastening structures such as screws and bolts, or the housing 52 of the detection component 50 can be bonded to the drive component 30.

[0052] In some embodiments, the detection component 50 is integrated into the drive component 30. This can mean that the detection component 50 is assembled into the drive component 30 as a complete structure, or it can mean that the core of the detection component 50 (including a rotating shaft, an angle measuring element, a second electrical connection part 51, etc.) is directly assembled into the drive component 30 and the housing of the drive component 30 is used as a protective enclosure.

[0053] In some embodiments, the detection component 50 may be partially embedded within the drive component 30. This helps to arrange the detection component 50 and the drive component 30 more compactly, helps the detection component 50 to make better use of the internal space of the drive component 30, and reduces the space occupied by the detection component 50 protruding from the drive component 30.

[0054] In some embodiments, both the second electrical connection portion 51 and the first electrical connection portion 32 may be located at least partially outside the drive assembly 30. This facilitates electrical connection between the circuit board 60 and the second electrical connection portion 51, the first electrical connection portion 32, etc., which helps to simplify the electrical connection process, simplify the layout of the circuit board 60, reduce the complexity of the circuit board 60, improve assembly efficiency, and facilitate the design and manufacture of the circuit board 60.

[0055] Furthermore, since the electrical connection parts (first electrical connection part 32 and second electrical connection part 51) are externally located, it is convenient for users to observe the connection status between the circuit board 60 and the electrical connection parts. This facilitates visual management of the connection points, ensures the stability and reliability of the connection, and helps reduce system failures caused by poor connections. Moreover, during maintenance, there is no need to disassemble the drive assembly 30 internally; users can directly inspect and maintain the electrical connection parts and wiring from the outside of the drive assembly 30. This helps reduce maintenance difficulty, shorten maintenance time, and improve the maintenance efficiency of the drone 100.

[0056] In some embodiments, the second electrical connection portion 51 may be located partially or entirely on the outside of the drive assembly 30.

[0057] In some embodiments, the first electrical connection portion 32 may be located partially or entirely on the outside of the drive assembly 30.

[0058] In some embodiments, both the second electrical connection 51 and the first electrical connection 32 can be located on the side of the drive unit 101 opposite to the bottom 12 of the fuselage 10. This effectively utilizes the vertical space inside the drone 100, facilitating user inspection and maintenance of the electrical connections on the side of the drive unit 101 opposite to the bottom 12 of the fuselage 10. It also helps prevent direct impact on the electrical connections caused by vibration and collision between the drive unit 101 and the bottom 12 of the fuselage 10, enhancing the protection of the second electrical connection 51 and the first electrical connection 32, extending their service life, and improving the stability and reliability of the drone 100.

[0059] In some embodiments, the circuit board 60 may include a first board body 610 and a second board body 620. The first board body 610 is electrically connected to the first electrical connection portion 32, one end of the second board body 620 is electrically connected to the first board body 610, and the other end of the second board body 620 is electrically connected to the second electrical connection portion 51. Thus, by dividing the circuit board 60 into two boards and electrically connecting them to the detection component 50 and the driving component 30 respectively, the complexity of the circuit board 60 is reduced, and the circuit connection is simplified.

[0060] In some embodiments, the first electrical connection portion 32 may include a plurality of conductive posts 320, which are distributed along the length direction of the first plate 610 and also along the width direction of the first plate 610. The plurality of conductive posts 320 are electrically connected to the first plate 610. Thus, the distribution of the plurality of conductive posts 320 helps to match the length and width directions of the first plate 610, making better use of the spatial positions of the first plate 610 in both directions. This helps to improve the utilization rate of the first plate 610 and also helps to prevent the volume of the first plate 610 from being too large, leaving too much space unused, thereby contributing to a smaller size of the first plate 610.

[0061] In this application, the term "multiple" means two or more, such as two, three, four, five, six or other quantities.

[0062] In some embodiments, the number of conductive posts 320 can be four, and the four conductive posts 320 can be arranged in a two-row, two-column layout.

[0063] In some embodiments, the second electrical connection portion 51 may include a plurality of pins 510 distributed along the length direction of the second board body 620 and electrically connected to the second board body 620. Thus, the distribution of the plurality of pins 510 helps to match the length direction of the second board body 620, making better use of the space in the length direction of the second board body 620. The second board body 620 does not need to be enlarged in the width direction to accommodate the plurality of pins 510, which helps to prevent the volume of the second board body 620 from becoming too large, leaving more space and thus contributing to a smaller size of the second board body 620.

[0064] In some embodiments, the number of pins 510 can be three, and the three pins 510 are distributed sequentially along the length direction of the second plate 620.

[0065] In some embodiments, the drive assembly 30 may include a power output shaft 31, a drive motor 33, and a reducer 34. The driving force output by the power output shaft 31 is used to drive the landing gear 40 to switch between different positions. The reducer 34 is connected between the output end of the drive motor 33 and the power output shaft 31. The electrical connection portion of the drive motor 33 may serve as the first electrical connection portion 32 of the drive assembly 30.

[0066] Thus, the combined use of reducer 34 and drive motor 33 enables precise control of the landing gear 40's rotational speed. The gear ratio of reducer 34 can adjust the output speed, helping to improve the smoothness of the landing gear 40 during position switching. Furthermore, reducer 34 can increase the torque of the power output shaft 31. Even with a constant output power of drive motor 33, reducer 34 can achieve greater torque output from the power output shaft 31 through the reduction ratio, contributing to improved stability and load-bearing capacity of the landing gear 40 in complex environments. Since reducer 34 bears most of the torque output, it helps reduce the direct pressure on drive motor 33, reducing motor wear, extending the service life of drive motor 33, and lowering maintenance costs.

[0067] In some embodiments, the reducer 34 may be a reduction gear set.

[0068] In some embodiments, the drive motor 33 and the detection component 50 can be located on opposite radial sides of the power output shaft 31. This separation of the drive motor 33 and the detection component 50 by the power output shaft 31 helps reduce electromagnetic interference between them, particularly the interference of the magnetic field generated by the drive motor 33 during operation on the detection component 50, thus improving the accuracy and stability of angular displacement measurement. Furthermore, the heat generated by the drive motor 33 during operation helps reduce the thermal impact on the detection component 50.

[0069] In some embodiments, the detection component 50 may include a rotary angular displacement sensor 501, the shaft 53 of which is connected to the power output shaft 31. This helps ensure that the shaft 53 of the angular displacement sensor 501 rotates synchronously with the power output shaft 31, allowing the angular displacement sensor 501 to directly reflect the rotation of the power output shaft 31, thus improving the accuracy of the angular displacement sensor 501 measurement and ensuring accurate determination of the landing gear 40's position.

[0070] In some embodiments, the angular displacement sensor 501 may be a potentiometer-type angular displacement sensor.

[0071] In some embodiments, the rotating shaft 53 of the angular displacement sensor 501 and the power output shaft 31 can be arranged in parallel. This parallel arrangement can effectively reduce the space occupied by the angular displacement sensor 501 and the power output shaft 31, which helps to make the angular displacement sensor 501 and the power output shaft 31 more compact, helps to avoid the space waste caused by the vertical or cross arrangement of the two, helps to optimize the spatial layout within the UAV 100, and provides more installation space for other components.

[0072] In some embodiments, the rotating shaft 53 of the angular displacement sensor 501 and the power output shaft 31 can be connected by a gear structure.

[0073] In some embodiments, the drive device 101 may further include a first transmission gear 71 and a second transmission gear 72. The first transmission gear 71 is mounted on the power output shaft 31, and the second transmission gear 72 is mounted on the rotating shaft 53 of the angular displacement sensor 501 and meshes with the first transmission gear 71. Thus, the gear transmission has high precision and efficiency, which helps to ensure that the rotational motion of the power output shaft 31 is efficiently and accurately transmitted to the rotating shaft 53 of the angular displacement sensor 501, thereby improving transmission efficiency.

[0074] Furthermore, gear transmission enables precise proportional relationships, facilitating the determination of the rotational speed of the shaft 53 of the angular displacement sensor 501 by adjusting the gear ratio of the first transmission gear 71 and the second transmission gear 72. This ensures accurate proportional transmission and guarantees the accuracy of angular displacement measurements. Gear transmission also boasts high wear resistance and a long service life. Compared to other transmission methods, such as belt or chain drives, gear transmission can withstand greater torque and more frequent start-stop cycles, contributing to extended system lifespan, reduced maintenance frequency and costs. Additionally, it features a compact structure, small footprint, lower noise, and less vibration, enhancing the quietness and stability of the UAV 100's operation.

[0075] In some embodiments, the first transmission gear 71 and the power output shaft 31 can be fixed by a key (such as a flat key, a semi-circular key, a spline, etc.) or an interference fit.

[0076] In some embodiments, the second transmission gear 72 and the rotating shaft 53 of the angular displacement sensor 501 can be fixed by a key (such as a flat key, a semi-circular key, a spline, etc.) or an interference fit.

[0077] In some embodiments, there are multiple landing gears 40, and the multiple landing gears 40 may include a first landing gear 410 and a second landing gear 420. One of the first landing gear 410 and the second landing gear 420 may serve as the landing gear on the left side of the drone 100, and the other may serve as the landing gear on the right side of the drone 100.

[0078] In some embodiments, the drive assembly 30 may include a first output shaft 310 and a second output shaft 320. Both the first output shaft 310 and the second output shaft 320 can serve as the structure of the power output shaft 31.

[0079] The first landing gear 410 is mounted on the first output shaft 310. The driving force output by the first output shaft 310 is used to rotate the first landing gear 410 to switch between different positions. The second landing gear 420 is mounted on the second output shaft 320. The driving force output by the second output shaft 320 is used to rotate the second landing gear 420 to switch between different positions. For example, the driving force output by the first output shaft 310 is used to rotate the first landing gear 410 relative to the fuselage 10 to the supported position, and the driving force output by the second output shaft 320 is used to rotate the second landing gear 420 relative to the fuselage 10 to the supported position. Another example is that the driving force output by the first output shaft 310 is used to rotate the first landing gear 410 relative to the fuselage 10 to the retracted position, and the driving force output by the second output shaft 320 is used to rotate the second landing gear 420 relative to the fuselage 10 to the retracted position.

[0080] In some embodiments, the first output shaft 310 and the second output shaft 320 are coaxially arranged, and the detection component 50 is used to detect the rotation angle of the first output shaft 310 or the second output shaft 320. Thus, the coaxial arrangement of the first output shaft 310 and the second output shaft 320 helps the first landing gear 410 and the second landing gear 420 to switch positions synchronously, helping to avoid problems such as fuselage imbalance or landing stability issues caused by asynchrony, and improving the maneuverability and safety of the UAV 100 during takeoff and landing. Furthermore, the coaxial design allows the UAV 100 to simultaneously control the first landing gear 410 and the second landing gear 420 using the same drive unit 101, which helps simplify the mechanical structure, reduce the number of parts, and help reduce the overall weight of the UAV 100.

[0081] In some embodiments, the coaxial arrangement can be understood as the first output shaft 310 and the second output shaft 320 being different output ends of the same shaft, or as the output ends of two shafts connected by a coupling or other structure.

[0082] In this application, unless otherwise expressly specified or limited, the terms "assembly," "connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a mechanical connection; they can be a direct connection or an indirect connection via an intermediate medium; they can refer to the internal communication of two components; they can refer to mere surface contact; or they can refer to surface contact connection via an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0083] Furthermore, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as referring to specific or particular items.
