Description

Technical Field

[0001] The present invention relates to the technical field of drone nests, and in particular to a fast-charging drone nest, a drone, and an automatic charging method. Background Art

[0002] A drone is an unmanned aircraft, controlled by a radio remote control and its own programmable controller, or operated fully or intermittently autonomously by an onboard computer. Compared to manned aircraft, drones are often better suited for missions deemed too "dull, dirty, or dangerous." Drones can be categorized by application into military and civilian applications. Civilian applications are primarily quadcopters, with applications in a variety of fields, including aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, and disaster relief. Civilian drones, on the other hand, are all powered by electricity and require batteries. As battery capacity increases, their size and weight increase, placing a significant burden on the drone. Consequently, drones generally have shorter flight ranges. For example, when conducting long-distance power transmission line inspections, drone nests are often installed at intervals along the flight path. When the battery is low, the drone can recharge at the nest and resume its mission.

[0003] However, there are two main methods of charging drone nests in the existing technology. One is wireless charging, where the drone can be charged by landing directly on the nest without any wired connection. However, the charging power of wireless charging technology is low, the loss is serious, and the heat is high. The other is contact charging through contacts. Although it can achieve a higher charging power than wireless charging, the drone needs to land precisely in the designated charging area and align the contacts, resulting in a slow landing speed and a low charging success rate. In addition, the contacts are exposed to the outside for a long time and are prone to oxidation, resulting in poor contact and a high failure rate. Therefore, it is necessary to improve it. Summary of the Invention

[0051] The following are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.

[0052] A fast-charging drone nest, such as Figures 1 to 7As shown, it includes a frame 1, a box body 2, an automatic positioning device, a charging mechanism and a control circuit. The frame 1 is installed inside the box body 2. A parking platform 11 is provided on the upper part of the frame 1. The charging mechanism and the automatic positioning device are installed on the frame 1. The control circuit is electrically connected to the automatic positioning device and the charging mechanism respectively. The automatic positioning device is provided with a longitudinal positioning mechanism 3 and a transverse positioning mechanism 4. The longitudinal positioning mechanism 3 includes a clamping fixed rod 31, a clamping sliding rod 32, a clamping drive mechanism and two longitudinal slide rails 35. The clamping fixed rod 31 is fixedly installed on the rear edge of the parking platform 11. The two longitudinal slide rails 35 are respectively installed on the left and right sides of the parking platform 11. The left and right ends of the clamping sliding rod 32 are respectively slidably installed on the two longitudinal slide rails 35. The clamping drive mechanism is connected to the clamping sliding rod 32, and the clamping sliding rod 32 moves away from and close to the clamping fixed rod 31; the transverse positioning mechanism 4 includes A pushing sliding rod 41, a pushing driving mechanism and two transverse slide rails 45, the two transverse slide rails 45 are respectively installed on the front and rear sides of the parking platform 11, the left and right ends of the pushing sliding rod 41 are respectively slidably installed on the two transverse slide rails 45, the pushing driving mechanism is transmission-connected to the pushing sliding rod 41, the charging mechanism is arranged at one end of the clamping fixing rod 31, the pushing sliding rod 41 moves away from and close to the charging mechanism, and the pushing sliding rod 41 and the clamping sliding rod 32 are cross-arranged; the charging mechanism is provided with a charging seat 51, a charging plug 52 for connecting to the drone charging socket 85 and a position signal transmitter, the charging seat 51 is installed at one end of the clamping fixing rod 31, the charging plug 52 is arranged on the charging seat 51 and protrudes from the side of the charging seat 51 facing the pushing sliding rod 41, the position signal transmitter is fixedly installed on the charging seat 51, and the position signal transmitter and the charging plug 52 are respectively electrically connected to the control circuit.

[0053] Traditional drone nests are charged either through wireless charging or through contact connection. Wireless charging often has a designated charging area, and the drone needs to land accurately in the designated area. If the landing deviation is large, it will lead to failure to charge, requiring a second takeoff and landing, and the landing speed is slow. It also consumes more electricity during landing, and it is easy to lose power and fall during landing. Contact connection charging requires more precise landing requirements. In order to ensure conductivity, the contacts are often made of copper. Long-term exposure to the outside is prone to oxidation, resulting in insufficient charging contact or even failure to charge, poor stability, and low charging power and slow charging speed. When the drone of the present invention lands, it receives a position signal transmitter. To obtain the position of the charging seat 51, you only need to adjust the landing posture and rotate the charging socket 85 to the side facing the charging seat 51. There is no need for complicated landing steps. The drone is positioned horizontally through the automatic positioning device so that the drone reaches the charging position. There is no need to use complex landing auxiliary mechanisms for precise landing, which reduces landing accuracy, increases the landing speed of the drone, simplifies the structure, reduces costs, improves landing efficiency, and reduces accidental power outages and crashes during landing due to insufficient power of the drone. Wired charging is performed through a wired connection, with a charging power of up to 240W, fast charging speed, no interference from external magnetic fields, and strong stability. There is no need for manual wiring, a high degree of automation, and easy use.

[0054] Specifically, the clamping fixing rod 31 is provided with an arc-shaped first fixing groove 311 on the side facing the clamping sliding rod 32, and the clamping sliding rod 32 is provided with an arc-shaped second fixing groove on the side facing the clamping fixing rod 31. A transverse slide rail 45 is installed on the rear side of the longitudinal slide rail 35, and the other transverse slide rail 45 is installed on the front side of the parking platform 11. The middle part of the clamping fixing rod 31 and the clamping sliding rod 32 is respectively provided with a penetrating slide groove 36 along the length direction, and the left and right ends of the pushing sliding rod 41 respectively pass through the two slide grooves 36 and are slidably connected to the two transverse slide rails 45. When the drone is landing, the clamping sliding rod 32 moves toward the clamping fixing rod 31 until the drone is clamped between the clamping sliding rod 32 and the clamping fixing rod 31. The drone is clamped more tightly in the middle through the arc-shaped first fixing slot 311 and the second fixing slot to prevent the drone from accidentally falling off. When clamping, the cross bar 83 of the drone falls into the first fixing slot 311 and the second fixing slot. When clamped, the outer side surfaces of the two cross bars 83 respectively abut against the inner side walls of the first fixing slot 311 and the second fixing slot, so that the two cross bars 83 are tangent to the first fixing slot 311 and the second fixing slot, respectively, thereby further improving the positioning accuracy, pushing the sliding rod 41 to slide in the slide groove 36, and can accurately press against the ends of the two cross bars 83 when performing lateral positioning, while reducing the installation space.

[0055] Specifically, a buffer mechanism is provided at one end of the clamping sliding rod 32 close to the charging mechanism, and the buffer mechanism includes a buffer rod 61 and a buffer spring 62. A buffer slide hole 321 is opened along the length direction at one end of the clamping sliding rod 32 close to the charging mechanism. The buffer slide hole 321 is connected with the slide groove 36 of the clamping sliding rod 32. The buffer rod 61 is slidably installed in the buffer slide hole 321. The inner end of the buffer rod 61 is provided with a buffer portion 611, and the outer end of the buffer rod 61 is provided with a limiting portion 612. The buffer spring 62 is sleeved on the buffer rod 61, and one end of the buffer spring 62 presses against the buffer portion 611 and the other end presses against the inner wall of the slide groove 36. When performing lateral positioning, the push-slide rod 41 is moved toward the drone, pushing the drone toward the charging seat 51. The drone first touches the buffer portion 611 of the buffer rod 61. Under the push of the push-slide rod 41, the buffer rod 61 slides outward and squeezes the buffer spring 62 at the same time; the buffer mechanism gives the drone a reverse thrust in the moving direction to prevent the drone from moving too fast and causing offset and jamming; after charging is completed, the push-slide rod 41 is moved in the opposite direction, and the buffer spring 62 is gradually released. Under the action of the buffer spring 62, the buffer rod 61 is pushed to slide inward, thereby pushing the drone out and disconnecting the charging socket 85 and the charging plug 52.

[0056] Specifically, a plurality of balls 37 are spaced apart on the upper and / or lower walls of the chute 36. The balls 37 roll in engagement with the push-slide rod 41. The balls 37 reduce the contact area between the push-slide rod 41 and the inner wall of the chute 36, thereby reducing friction. The rolling balls 37 make the push-slide rod 41 slide more smoothly, thereby reducing the driving pressure of the push-drive mechanism.

[0057] Specifically, if Figure 3 As shown, the clamping drive mechanism includes a clamping drive motor 33, a longitudinal synchronous belt 34, two longitudinal synchronous wheels and two longitudinal screw rods. The two longitudinal screw rods are respectively rotatably installed in the inside of the two longitudinal slide rails 35 along the length direction, and the two longitudinal synchronous wheels are respectively fixedly installed on the same side of the two longitudinal screw rods. The longitudinal synchronous belt 34 is connected to the two longitudinal synchronous wheels, the clamping drive motor 33 is connected to any one of the longitudinal screw rods, and the control circuit is electrically connected to the clamping drive motor 33; the pushing drive mechanism includes a pushing drive motor 42, a transverse synchronous belt 43, two transverse synchronous wheels 44 and two transverse screw rods 46. The two transverse screw rods 46 are respectively rotatably installed in the inside of the two transverse slide rails 45 along the length direction, and the two transverse synchronous wheels 44 are respectively fixedly installed on the same side of the two transverse screw rods 46. The transverse synchronous belt 43 is connected to the two transverse synchronous wheels 44, the pushing drive motor 42 is connected to any one of the transverse screw rods 46, and the control circuit is electrically connected to the pushing drive motor 42. The clamping drive mechanism and the pushing drive mechanism are both driven by screws, which have a simple structure and low cost, and can provide effective fixing force when clamping and fixing.

[0058] Specifically, the charging mechanism is also provided with a telescopic drive mechanism, which includes an electric cylinder 53. A charging mounting portion 312 is provided at one end of the clamping and fixing rod 31. The charging mounting portion 312 is provided with a charging slide hole 313 that passes through the charging mounting portion 312 along the length direction of the clamping and fixing rod 31. The charging seat 51 is slidably mounted on the charging slide hole 313. The electric cylinder 53 is fixedly mounted on the outside of the charging mounting portion 312. The electric cylinder 53 is provided with a telescopic rod 54. The outer end of the telescopic rod 54 is inserted into the charging slide hole 313 and connected to the charging seat 51. The control circuit is electrically connected to the electric cylinder 53. The electric cylinder 53 drives the charging seat 51 to slide. When not charging, the charging seat 51 retracts into the charging slide hole 313 to protect the charging plug 52 from the sun and rain, thereby improving stability. When charging, after the automatic positioning device completes the positioning of the drone, the electric cylinder 53 pushes the charging seat 51 out until the charging plug 52 is inserted into the charging socket 85. When charging is completed, the electric cylinder 53 retracts the charging seat 51 into the charging slide hole 313 again, thereby disconnecting the charging socket 85 and the charging plug 52, preventing insufficient thrust of the buffer spring 62 from causing the charging socket 85 and the charging plug 52 to fail to disconnect, thereby further improving stability.

[0059] Specifically, the charging plug 52 adopts a Type-C plug, and the control circuit is further provided with a fast charging circuit and a detection unit. The control circuit is electrically connected to the fast charging circuit and the detection unit respectively, and the charging circuit and the detection unit are electrically connected to the Type-C plug respectively. When the detection unit detects that the Type-C plug is connected to the drone, the detection unit sends a charging signal to the fast charging circuit to drive the fast charging circuit to quickly charge the drone. The use of the Type-C plug improves adaptability. Type-C can carry a maximum charging power of 240W, which increases the charging speed. When the Type-C plug is inserted into the Type-C socket, the detection unit detects that a connection is established with the drone, and then sends a charging signal to the fast charging circuit to ensure that the fast charging circuit does not power the Type-C plug when no connection is established with the drone, thereby reducing energy consumption, preventing electric shock, and improving safety.

[0060] Specifically, the drone nest is also provided with a docking monitoring device, which includes at least one infrared transmitter 71 and at least one infrared receiver 72. The infrared transmitter 71 is installed on the clamping fixed rod 31 or the clamping sliding rod 32, and the infrared receiver 72 is installed on the clamping sliding rod 32 or the clamping fixed rod 31. The infrared transmitter 71 and the infrared receiver 72 are arranged opposite to each other, and the infrared receiver 72 receives the infrared signal emitted by the infrared transmitter 71 in real time. The infrared transmitter 71 and the infrared receiver 72 are electrically connected to the control circuit respectively. In the initial state, the clamping sliding rod 32 moves to the frontmost side of the parking platform 11, and the pushing sliding rod 41 moves to the farthest end of the charging mechanism. When the UAV lands, the UAV blocks the infrared connection signal between the infrared transmitter 71 and the infrared receiver 72. The infrared receiver 72 cannot receive the infrared signal and then sends a docking signal to the control circuit. The control circuit automatically starts the automatic positioning device. No manual operation is required throughout the process, thereby improving the degree of automation. Preferably, after the UAV docks, the UAV sends a docking signal to the control circuit of the UAV nest. The control circuit starts the automatic positioning device only after receiving the docking signal from the docking monitoring device and the UAV at the same time, ensuring that the automatic positioning device is started after the UAV has landed stably.

[0061] The parking platform 11 is also provided with an air cooling mechanism, which includes a heat sink 12 and at least one fan. The parking platform 11 is provided with a cooling chamber with an upward opening, and the heat sink 12 is covered in the cooling chamber. The heat sink 12 is provided with a plurality of heat dissipation ports 121 arranged at intervals. The fan is fixedly installed on the frame 1, and the air outlet of the fan is connected to the cooling chamber; two box covers 21 are provided on the upper part of the box body 2, and the two box covers 21 are respectively hinged to the box body 2 through a connecting rod assembly 22. A cover opening drive mechanism is provided inside the box body 2, and the cover opening drive mechanism is electrically connected to the transmission structure. The fan blows the air into the cooling chamber and then blows it upward from each heat dissipation port 121, thereby dissipating the heat of the drone, reducing the heat generated during charging, preventing the heating of the drone from causing a decrease in charging power, and further increasing the charging speed. Correspondingly, heat dissipation holes are opened on the box cover 21, and an air inlet is opened on the box body 2. Cold air enters the box body 2 from the air inlet, and is blown toward the drone under the action of the fan. The cold air takes away the heat of the drone and becomes hot air, which is blown out from the heat dissipation holes to establish a circulating air duct and improve the heat dissipation effect. The box cover 21 protects the components and drone inside the box body 2, extending the service life of the drone and the drone nest.

[0062] A fast-charging drone, such as Figure 8As shown, the drone includes a fuselage 81, landing gear, a charge management circuit, and a rechargeable battery 82. The battery and charge management circuit are both installed inside the fuselage 81, and the landing gear is installed at the bottom of the fuselage 81. The landing gear includes two crossbars 83 and at least two vertical rods 84. The upper ends of the two vertical rods 84 are respectively fixedly connected to the fuselage 81, and the lower ends of the two vertical rods 84 are respectively fixedly connected to the corresponding two crossbars 83. The two crossbars 83 are spaced and arranged in parallel. The outer end of each crossbar 83 is provided with a charging socket 85, which adopts a Type-C socket. The rechargeable battery 82 has two built-in battery cells, which are electrically connected to the charge management circuit, and the charge management circuit is electrically connected to the Type-C socket. During fast charging, both battery cells are charged simultaneously, at least doubling the charging efficiency. Preferably, a Type-C socket is provided at each end of the two cross bars 83, and each Type-C socket is electrically connected to the charging management circuit. Before landing, the drone only needs to make the cross bar 83 as parallel as possible to the clamping fixing rod 31, which simplifies the posture adjustment steps and further improves the landing speed.

[0063] A fast charging automatic charging method comprises the following steps:

[0064] In the charging preparation step, the drone sends a charging request signal to the drone nest, and the control circuit controls the cover-opening drive mechanism to open the two box covers 21. Preferably, the drone sends the charging request signal to the control center, which then sends the coordinates of a nearby idle drone nest to the drone and simultaneously sends the charging request signal to the drone nest. Through unified coordination by the control center, drone charging efficiency is improved and drones are prevented from flying to drone nests without charging locations.

[0065] Landing identification steps, such as Figure 4 As shown, the position signal transmitter transmits a position signal to the UAV. After the UAV determines the position of the charging mechanism, it adjusts its posture so that the Type-C socket installed on the crossbar 83 faces the Type-C plug and lands on the parking platform 11. The docking monitoring device detects that the UAV is docked and sends a docking signal to the control circuit; the position signal transmitter uses an electromagnetic wave transmitter or an infrared transmitter, and a receiver for receiving the electromagnetic wave transmitter or infrared transmitter signal is installed on the UAV accordingly, so that the UAV adjusts its posture and lands.

[0066] UAV positioning step: After the UAV lands, it sends a docking signal to the control circuit. The UAV blocks the infrared connection signal between the infrared transmitter 71 and the infrared receiver 72. The infrared receiver 72 cannot receive the infrared signal and then sends a docking signal to the control circuit. After the control circuit receives two docking signals at the same time, Figure 5As shown, the control circuit controls the clamping drive motor 33 to drive the clamping sliding rod 32 to move toward the drone until the drone is clamped between the clamping sliding rod 32 and the clamping fixed rod 31, completing the longitudinal positioning; Figure 6 As shown, the control circuit controls the pushing drive motor 42 to drive the pushing sliding rod 41 to move toward the UAV until the pushing sliding rod 41 presses the UAV onto the buffer mechanism, completing the lateral positioning.

[0067] Plug insertion steps, such as Figure 7 As shown, the control circuit controls the electric cylinder 53 to drive the charging base 51 to move toward the drone until the Type-C plug is inserted into the Type-C socket;

[0068] Identify the charging steps, the detection unit detects that the Type-C plug is connected to the drone, and sends a charging signal to the fast charging circuit. The fast charging circuit quickly charges the drone. At the same time, the control circuit controls the cover opening drive mechanism to close the two box covers 21 and turn on the fan.

[0069] After charging is completed, the control circuit controls the electric cylinder 53 to drive the charging seat 51 to retract into the charging slide hole 313, disconnecting the Type-C charging plug and the Type-C socket, pushing the sliding rod 41 to move in the opposite direction, and gradually releasing the buffer spring 62. Under the action of the buffer spring 62, the buffer rod 61 is pushed to slide inward, thereby pushing the drone out; the clamping sliding rod 32 moves forward to release the drone, and the two box covers 21 are opened, the drone flies out, and charging is completed.
