[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

It should be understood that such terms can be used interchangeably where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, products, or apparatus.
[0029] See Figure 1 This invention provides a drone 100 and a drone power supply device 10. The drone 100 includes the drone power supply device 10 and a drone body 20. The drone power supply device 10 is disposed as follows: Figure 1 Above the main body 20 of the drone shown.
[0030] Further, see Figure 2 and Figure 3The UAV power supply device 10 includes: a mounting platform 12, a guide structure 14, a first gripper 162, and a second gripper 164. The guide structure 14 includes a first guide portion 142 and a second guide portion 144 that are interconnected and intersecting. The first guide portion 142 and the second guide portion 144 are disposed on the mounting platform 12 and form a fan-shaped guide space 146 on the side away from the mounting platform 12. The fan-shaped guide space 146 has a top axis area 1462, which is formed at the intersection of the first guide portion 142 and the second guide portion 144; the top axis area 1462 is used to accommodate a cable 15. The first gripper 162 is movably connected to the mounting platform 12 on one side of the first guide portion 142, and the second gripper 164 is movably connected to the mounting platform 12 on one side of the second guide portion 144. The first gripper 162 and the second gripper 164 can reciprocate relative to the guide structure 14 and can connect to each other at the intersection and lock the cable 15.
[0031] First, combined Figure 1 and Figure 2 The power supply device 10 for the drone provided in this embodiment of the invention is disposed on the main body 20 of the drone. When the drone 100 needs to dock with the cable 15, the drone 100 will gradually approach the cable 15 from below. Therefore, the guide structure 14, by setting the fan-shaped guide space 146, will dock with the cable 15 with a larger tolerance space. The cable 15 will be more easily placed within the fan-shaped guide space 146. After the cable 15 is in the fan-shaped guide space 146, since the first guide part 142 and the second guide part 144 are arranged crosswise, when the drone 100 continues to rise at this time, the cable 15 will... Figure 2 In the fan-shaped guide space 146 shown, the cable 15 gradually moves downward relative to the guide structure 14 until it reaches the top shaft area 1462 and is in a position as shown. Figure 3 The position relative to the guide structure 14 is shown. During the above process, due to the intersecting arrangement of the first guide portion 142 and the second guide portion 144, the drone 100 can be gradually guided upwards, so that the cable 15 eventually resides in the top axis region 1462. For example, the cable 15 abuts against the inner wall of the first guide portion 142, and as the drone 100 rises relative to the cable 15, the cable 15 will slide into the top axis region 1462 while still attached to the inner wall of the first guide portion 142.
[0032] When the cable 15 is in the top shaft area 1462, the first gripper 162 and the second gripper 164 move from... Figure 2 The state shown moves to Figure 3The state shown indicates that the two devices are interconnected and the cable 15 is locked. Therefore, the UAV power supply device 10 provided in this embodiment of the invention reduces the difficulty of docking the UAV with the high-voltage overhead cable by setting the guide structure 14, and increases the fault tolerance space for docking; and in conjunction with the first gripper 162 and the second gripper 164, the UAV locks the high-voltage overhead cable in the air, thereby realizing the smooth docking of the UAV with the high-voltage overhead cable.
[0033] Further, see Figure 4 The first gripper 162 and the second gripper 164 are both U-shaped, and each of the first gripper 162 and the second gripper 164 contains a corresponding U-shaped electromagnetic induction element. When the first gripper 162 and the second gripper 164 are connected to each other, they form a ring-shaped limiting structure and lock the cable. Furthermore, the two U-shaped electromagnetic induction elements form a ring-shaped electromagnetic induction structure. Therefore, in this embodiment of the invention, the first gripper 162 and the second gripper 164, through the ring structure formed by their interconnection, limit the cable 15. Moreover, the first gripper 162 and the second gripper 164 not only function to lock the cable 15, but also, by correspondingly providing the U-shaped electromagnetic induction elements 166 within the first gripper 162 and the second gripper 164, achieve the technical effect of locking the cable 15 with a ring structure, and also achieve the technical effect of forming a closed magnet by cooperating with the ring-shaped magnetic induction structure formed by the two U-shaped electromagnetic induction elements 166.
[0034] Specifically, the U-shaped electromagnetic induction element can be formed by stacking silicon steel sheets to create a U-shape, and a conductor such as a copper coil can be wound around the silicon steel sheets, for example, at the bottom of the U-shaped structure, to form a current transformer. Therefore, the UAV power-collecting device 10 provided in this embodiment can collect the magnetic field energy around the high-voltage cable and convert it into electrical energy to charge the UAV's battery without altering the power infrastructure. The UAV 100 can grasp the high-voltage cable through the UAV power-collecting device 10 and attach and hover on the high-voltage cable, simultaneously collecting power.
[0035] When the two U-shaped electromagnetic induction elements form a closed loop and, under the influence of the current flowing through the cable 15, form a closed magnet, the conductor will be subjected to the magnetic field of the closed magnet, generating a magnetically induced current. This achieves the technical effect of supplying power to the power source, such as a lithium battery, included in the UAV 100. Furthermore, to insulate and protect the internal circuitry of the current transformer, the U-shaped electromagnetic induction element or the current transformer has an insulating encapsulation layer. This insulating encapsulation layer can be used, for example, by applying insulating glue and molding to encapsulate the U-shaped electromagnetic induction element and the conductor, while leaving the contact surfaces of the two U-shaped electromagnetic induction elements unencapsulated. Additionally, to further enhance insulation protection, the first gripper 162 and the second gripper 164 can also be made of insulating materials such as plastic. Thus, the first gripper 162 and the second gripper 164 can both lock and connect to the cable 15 and provide insulation protection for the current transformer. Furthermore, to better provide insulation and ensure that the UAV power supply device 10 can smoothly connect to the cable 15 through the guide structure 14, the guide structure 14 can be made of an insulating material with a certain strength, such as polyetheretherketone (PEEK), and the guide structure 14 can be as follows: Figure 2 The guide structure 146 is positioned above the first gripper 162 and the second gripper 164, thus extending above them. Therefore, when the UAV power-collecting device 10 approaches the cable 15 from below, the cable 15 generally does not come into contact with the first gripper 162 and the second gripper 164, allowing the cable 15 to smoothly fall into the guide space 146 and ultimately into the top axis area 1462. Furthermore, through the aforementioned guide structure 14, and because it is made of insulating material, the guide structure 14 also provides insulation protection for other circuit components of the UAV 100.
[0036] Further, see Figure 4The UAV power supply device 10 also includes a transmission belt 182. The mounting platform 12 is provided with a first transmission member 184 and a second transmission member 186 along the direction of reciprocating motion. The first transmission member 184 and the second transmission member 186 are respectively disposed on both sides of the guide structure 14; the transmission belt 182 is sleeved on the first transmission member 184 and the second transmission member 186, forming opposite sides of the transmission belt; the first gripper 162 and the second gripper 164 are respectively connected to the two sides of the transmission belt. By sleeved on the first transmission member 184 and the second transmission member 186, the transmission belt 182 is arranged in a ring, forming opposite sides of the transmission belt 182. Based on this, the first gripper 162 and the second gripper 164 are disposed on the opposite sides of the transmission belt 182, thereby achieving that when the ring-shaped transmission belt 182 rotates, for example in… Figure 4 When the transmission belt 182 rotates counterclockwise, the first gripper 162 and the second gripper 164 will move closer to each other, thus bringing them sufficiently close together. The connection between the first gripper 162 and the second gripper 164 is achieved through the electromagnetism generated by the built-in U-shaped electromagnetic induction elements. Conversely, when the transmission belt 182 rotates clockwise, the first gripper 162 and the second gripper 164 can separate.
[0037] Furthermore, see Figure 4 The UAV power supply device 10 also includes a drive motor 188. The drive motor 188 is connected to the mounting platform 12; the first transmission member 184 is the driving wheel, and the second transmission member 186 is the driven wheel; the shaft of the drive motor 188 is connected to the driving wheel. Thus, the UAV power supply device 10 provided in this embodiment of the invention can achieve relative movement between the first gripper 162 and the second gripper 164 by using only a single drive motor 188, thereby reducing the production cost of the UAV power supply device 10. Specifically, the drive motor 188 is, for example, a DC servo module integrating a motor, reducer, controller, driver, and network, which is lightweight and small in size. The transmission belt 182 is, for example, a T-tooth MXL type, the driving wheel is an MXL type synchronous pulley with small steps and flanges, the driven wheel is an MXL type synchronous pulley with bearings and flanges, and the driving wheel is fixedly connected to the output shaft of the drive motor 188.
[0038] Furthermore, a limit rod 122 is provided on the mounting platform 12, and the limit rod 122 is arranged along the direction of the reciprocating motion. The first gripper 162 and the second gripper 164 are slidably connected to the limit rod 122. By setting the limit rod 122, the movement direction of the first gripper 162 and the second gripper 164 can be further limited to ensure the movement stability of the first gripper 162 and the second gripper 164. In addition, a support base 124 can also be provided on the mounting platform 12, and the support base 124 is, for example, arranged on both sides of the mounting platform 12. Figure 4 As shown, the positions correspond to the first transmission member 184 and the second transmission member 186. The two ends of the limiting rod 122 can be respectively connected to the two support seats 124 to increase the connection reliability between the limiting rod 122 and the mounting platform 12. Specifically, the first gripper 162 and the second gripper 164 can each be provided with a sliding bearing 168 and a pressure plate 161, respectively. The limiting rod 122 is slidably connected through the sliding bearing 168, and the transmission belt 182 is connected through the pressure plate 161.
[0039] Further, see Figure 5 and Figure 6 The UAV power supply device 10 also includes a buffer locking mechanism 11. The buffer locking mechanism 11 is connected to the mounting platform 12 and is located at the intersection. When the first gripper 162 and the second gripper 164 are connected, they respectively engage with the buffer locking mechanism 11. To prevent damage caused by collisions between the first gripper 162 and the second gripper 164 during the connection process, the buffer locking mechanism 11 is provided. Because the first gripper 162 and the second gripper 164 need to engage with the buffer locking mechanism 11 for connection, the buffer locking mechanism 11 effectively reduces the moving speed of the first gripper 162 and the second gripper 164, thereby mitigating collisions and preventing damage. Furthermore, since the buffer locking mechanism 11 is connected to the mounting platform 12, when the first gripper 162 and the second gripper 164 are connected to each other and lock the cable 15, the weight of the mechanism below the mounting platform 12 will also be transferred to the first gripper 162, the second gripper 164, and the cable 15 through the buffer locking mechanism 11.
[0040] During the docking process between the cable 15 and the UAV power receiving device 10, the UAV power receiving device 10 often needs to be rotated and adjusted according to the extension direction of the cable 15 to ensure that the cable 15 successfully falls into the top shaft area 1462. Therefore, the buffer locking mechanism 11 avoids applying large forces to the limiting rod 122 and the support base 124; and as Figure 4 As shown, the position of the buffer locking mechanism 11, in conjunction with the positions of the two support seats 124, reduces the torque applied to the limiting rod 122 when the mounting platform 12 drives the guide structure 14 and the first gripper 162 and the second gripper 164 to rotate; thereby reducing the degree of deformation of the limiting rod 122 and the mounting platform 12.
[0041] Specifically, the buffer locking mechanism 11 includes a retainer 112 and an elastic buffer member 114. The retainer 112 has a slot on the side facing the first gripper 162. The elastic buffer member 114 connects to the retainer 112, with one end located within the slot. The first gripper 162 has a protrusion 1622; when the first gripper 162 engages with the buffer locking mechanism 11, the protrusion 1622 is located within the slot and abuts against the elastic buffer member 114. Specifically, the elastic buffer member 114 may be, for example, made of... Figure 7 The buffer ball 1142 and the buffer spring 1144 are connected. When the protrusion 1622 enters the slot, the protrusion 1622 abuts against the buffer ball 1142. The retainer 112 can be connected to the mounting platform 12 via a threaded connection structure such as a set nut 1146. Specifically, for example, a protrusion can be formed on the side of the protrusion 1622 that abuts against the buffer ball 1142. When the protrusion 1622 abuts against the buffer ball 1142, the protrusion 1622... Figure 7 When the first gripper 162 enters the slot as shown, the cooperation between the protrusion and the buffer locking mechanism 11 makes it difficult for the first gripper 162 to disengage from the buffer locking mechanism 11.
[0042] Furthermore, the card holder 112 can be, for example, a symmetrical structure, meaning the second gripper 164 engages with the buffer locking mechanism 11 using the same structural design. Moreover, through the aforementioned set nut 1146 and buffer spring 1144, users or manufacturers can adjust the screw-in depth of the set nut 1146 by combining the magnetic field strength of the electromagnetic induction structure, or replace different buffer springs 1144 to adjust the resistance generated by the elastic buffer member 114 when the protrusion 1622 enters the slot. This allows the elastic buffer member 114 to provide a better buffering effect and prevents the first gripper 162 and the second gripper 164 from failing to connect smoothly due to excessive resistance.
[0043] Further, see Figure 6 and Figure 8 The drone power supply device 10 also includes a rotating assembly 13. The rotating assembly 13 includes a housing 132 and a rotary motor 134. One end of the housing 132 is connected to the drone body 20. The rotary motor 134 is located inside the housing 132, and its shaft 136 is connected to the mounting platform 12, driving the mounting platform 12 to rotate and align with the top shaft area 1462 and the cable 15. When the drone power supply device 10 connects to the cable 15, the drone 100 needs to rotate to adjust the cable 15 so that it can smoothly fall into the top shaft area 1462 and allow the first gripper 162 and the second gripper 164 to lock the cable 15 securely. The rotation adjustment process can be achieved by rotating the drone body 20 to adjust the mounting platform 12. However, considering that the rotation angle of the drone body 20 may be difficult to adjust, the rotating assembly 13 is used for fine-tuning.
[0044] Specifically, the housing 132 is, for example, a flange support, and the rotary motor 134 is, for example, a flange support. Figure 8 The coupling 133, bearing 131, and bearing cap 138 serve to define and reinforce the rotating shaft 136. Furthermore, the flange support increases the distance between the UAV power supply device 10 and the UAV body 20, thereby protecting the various integrated circuits on the UAV body 20 from interference from the magnetic field induced by the cable 15. The rotary motor 134 may also be externally equipped with... Figure 6 The shielding housing 135 shown.
[0045] In addition, the UAV body 20 includes, for example, an avionics motherboard. To protect the avionics motherboard from the magnetic field generated by the cable 15, a metal shell of appropriate shape can be used to encapsulate and shield the avionics motherboard, depending on its location on the UAV body 20 and the distribution of the magnetic field lines generated by the cable 15. On the cables, electromagnetic noise crosstalk generated by the interconnecting cables is reduced through comprehensive measures such as using shielded twisted-pair cables, interface filtering, and ground clearance design.
[0046] Furthermore, the drone power supply device 10 may include, for example, a visual recognition sensor. The visual recognition sensor may be located on the top of the drone 100, for example, on the mounting platform 12 in an unobstructed position, and is used to identify the position of the cable 15 and transmit the position data of the cable 15 to the drone body 20, providing data guidance for the drone to autonomously locate the cable 15. Furthermore, since the drone power supply device 10 provided in this embodiment of the invention obtains power through electromagnetic induction, the drone body 20, the mounting platform 12, the buffer locking mechanism 11, and other structures can all be made of insulating materials or covered with insulating layers such as plastic or rubber. The drone body 20 may, for example, be made of carbon fiber material.
[0047] Furthermore, it is understood that the foregoing embodiments are merely illustrative examples of the present invention. Provided that the technical features do not conflict, are fixed and do not contradict the purpose of the present invention, the technical solutions of the various embodiments can be arbitrarily combined and used.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
