Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a lifting type UAV charging apron and a method for using the same. Background Art

[0002] As drone technology matures, its applications in civil, police, and military fields have rapidly expanded. Among them, small battery-powered drones dominate the market. However, battery life has always been a major factor restricting drone applications. Currently, drone charging pads are commonly used to ensure their endurance.

[0003] Traditional drone charging aprons mostly adopt a fixed design, and the installation area needs to be selected in a flat and open area, which limits its flexibility and adaptability in complex and changeable environmental conditions, such as urban high-rise areas or uneven terrain in the wild. In addition, traditional drone charging aprons are still stuck in the simple fixed-point docking and charging stage, and cannot adapt to the docking and charging needs of drones at different altitudes. The docking accuracy and docking stability between the charging plug and the socket are poor, which can easily lead to the problem of low charging efficiency. Summary of the Invention

[0004] In order to address the deficiencies of the above-mentioned prior art, the present invention provides a lifting drone charging pad and a method for using the same, which can adjust the height according to actual needs, ensuring the flexibility of drone use and its charging needs at different heights, and ensuring that the drone can accurately complete docking during landing, thereby improving charging efficiency.

[0005] The technical solution of the present invention is: a lifting type drone charging landing pad, comprising a vertical pole, a platform body, and a lifting mechanism that drives the platform body to move along the height direction of the vertical pole. The platform body has a charging seat for docking with a charging plug at the bottom of the drone. The vertical pole is provided with a cable for powering the charging seat and a drag chain for dragging the cable along the height direction of the vertical pole. The charging seat and the charging plug are mated through conical contact surfaces, and the inner conical groove of the charging seat and the outer cone of the charging plug are respectively provided with corresponding charging portions. The charging seat is provided with an electromagnet assembly for providing magnetic attraction to the charging plug. The installation method of combining the vertical pole and the lifting platform is not affected by environmental conditions and can automatically adjust the landing pad height according to the height requirements of the drone, thereby improving the flexibility and adaptability of the drone docking. The charging seat and the charging plug are connected by a conical surface mating method to ensure the reliability of the docking. The magnetic attraction of the electromagnet assembly improves the firmness of the charging plug after connection, thereby ensuring charging efficiency.

[0006] The charging portion of the outer cone comprises multiple conductive rings arranged side by side along the axis, while the charging portion of the inner conical slot comprises multiple conductive springs arranged side by side along the axis. One end of each conductive spring is embedded in the charging base and electrically connected to the cable, while the other end is curved inward toward the charging base. The charging base includes a mounting slot connected to the inner conical slot. The electromagnet assembly includes an electromagnet positioned within the mounting slot and an elastic member connecting the electromagnet to the bottom of the mounting slot. The charging base and the charging plug utilize elastic contact. The conductive springs exert an upward thrust on the outer cone of the charging plug. With the electromagnet and the charging plug in contact, the elastic member pulls down on the charging plug to balance this thrust. At this point, the conductive springs form interference contact with the conductive rings, further ensuring stable charging transmission.

[0007] A through hole is provided at the bottom of the mounting groove, a guide sleeve is fixed in the through hole, a guide shaft matching the guide sleeve is fixed at the bottom of the electromagnet, the elastic member is a tension spring sleeved on the outside of the guide shaft, and both ends of the tension spring are fixedly connected to the electromagnet and the guide sleeve respectively.

[0008] The platform body is slidably connected to the vertical pole via a sliding assembly. The lifting mechanism includes a winch located on the inner side of the lower end of the vertical pole and a fixed pulley located on the outer side of the upper end of the vertical pole. Rope holes are opened at positions corresponding to the vertical pole tube wall and the fixed pulley. The steel wire rope wound on the winch passes through the rope holes and the fixed pulley in sequence and is fixedly connected to the platform body.

[0009] The sliding assembly includes a guide rail portion fixed on the outside of the vertical pole and a pulley slidingly cooperating with the guide rail portion. The pulley is fixedly connected to the platform body via a pulley frame.

[0010] One end of the cable is embedded in the drag chain and electrically connected to the control unit. The other end of the cable passes through the cable hole and fixed pulley, then follows a line channel within the platform body to the charging station, where it is electrically connected to the charging unit on the inner conical groove. The cable has an integrated section tied to the wire rope at the location where it passes through the cable hole and fixed pulley. The length of this integrated section is no less than the distance the platform body moves along the height of the vertical pole. The cable is embedded in the drag chain and moves with the wire rope, ensuring that it is not excessively pulled or entangled.

[0011] A distance trigger module is installed on the platform body, and the distance trigger module is communicated with the lifting mechanism via the control unit. The distance trigger module is used to set the trigger distance with the platform body as the starting point. When the drone that needs to be charged enters the trigger distance, the distance trigger module sends information to the control unit and controls the operation of the lifting mechanism.

[0012] An infrared receiving module is provided on the outside of the charging base, and an infrared transmitting module is provided on the bottom of the drone. The infrared receiving module is communicatively connected with the electromagnet assembly via a control unit. The infrared receiving module is configured to receive infrared light emitted by the infrared transmitting module and send a signal to the control unit. The control unit controls the operation of the electromagnet assembly according to the received signal.

[0013] A spoke-type tension sensor is provided in the guide sleeve, and the spoke-type tension sensor is communicatively connected to the control unit. The spoke-type tension sensor is used to set a tension threshold. When the tension detected by the spoke-type tension sensor reaches the tension threshold, a signal is sent to the control unit, and the control unit controls the cable to supply power to the charging base.

[0014] A method for using a lifting drone charging pad comprises the following steps: S1. When the drone needs to dock, the platform body senses the approach of the drone through the distance trigger module, and the control unit controls the action of the lifting mechanism to drive the platform body down to the required height. The drone uses the visual guidance system to identify the position of the platform body and the charging base and lands; S2. The charging plug at the bottom of the drone is inserted into the inner conical groove of the charging base. The infrared receiving module outside the charging base receives the infrared light emitted by the infrared transmitting module at the bottom of the drone, and the control unit controls the electromagnet to energize. S3. The charging plug at the bottom of the drone continues to approach the electromagnet and is attracted by it. The tension spring is in a stretched state, exerting a downward force on the electromagnet and driving the charging plug to continue to move downward until the tension detected by the spoke-type tension sensor reaches the set tension threshold. At this time, the conductive rings of the charging plug maintain pressure contact with the conductive springs of the charging base, and the control unit controls the cable to supply power to the charging base, completing the charging of the drone.

[0015] In summary, the present invention mainly has the following beneficial effects: This solution adopts an installation method that combines a vertical pole and a lifting platform. It is not affected by environmental conditions and can automatically adjust the height of the helipad according to the height requirements of the drone, thereby improving the flexibility and adaptability of the drone docking. The charging seat and the charging plug are connected in a conical surface matching manner to ensure the reliability of the docking. Under the magnetic adsorption of the electromagnet assembly, the firmness of the charging plug after connection is improved, thereby ensuring charging efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the term "coupling" can refer to the manner in which electrical connection is achieved for signal transmission.

[0022] like Figure 1 and Figure 6 As shown, the present invention provides a lifting type drone charging apron, comprising a pole 1, a platform body 2 and a lifting mechanism for driving the platform body 2 to move in the height direction of the pole 1, the platform body 2 having a charging seat 8 for docking with a charging plug 301 at the bottom of the drone 3, a cable 701 for supplying power to the charging seat 8 and a drag chain 7 for dragging the cable 701 to move in the height direction of the pole 1 are arranged in the pole 1, and an installation method combining the pole 1 and the lifting platform is adopted, which is not affected by environmental conditions and can automatically adjust the height of the apron according to the height requirements of the drone 3, thereby improving the flexibility and adaptability of the drone 3 docking. Specifically, the lifting mechanism in this embodiment includes a winch 5 located on the inner side of the lower end of the pole 1 and a fixed slide located on the outer side of the upper end of the pole 1. Wheel 6, the platform body 2 is slidably connected to the vertical pole 1 through a sliding component, and rope holes are opened on the tube wall of the vertical pole 1 and the corresponding positions of the fixed pulley 6. The steel wire rope 501 wound on the winch 5 passes through the rope hole and the fixed pulley 6 in sequence and is fixedly connected to the platform body 2; one end of the cable 701 is built into the drag chain 7 and is electrically connected to the control unit, and the other end of the cable 701 passes through the rope hole and the fixed pulley 6 in sequence, and reaches the charging seat 8 position along the line channel 202 set in the platform body 2, and is electrically connected to the charging part on the inner conical groove 802. The cable 701 has an integrated section tied with the steel wire rope 501 at the position passing through the rope hole and the fixed pulley 6, and the length of the integrated section is not less than the distance the platform body 2 moves along the height direction of the vertical pole 1. The cable 701 moves together with the steel wire rope 501 through the integrated section. At the same time, the cable 701 inside the vertical pole 1 moves linearly along the height direction of the vertical pole 1 with the assistance of the drag chain 7, ensuring that the cable 701 is not excessively pulled and entangled during the lifting and lowering process of the platform body 2. Preferably, a connecting rope seat 204 for binding the steel wire rope 501 and a locking joint 203 for fixing the cable 701 to the platform body 2 are fixed on the platform body 2. A line channel 202 for laying the cable 701 is also provided on the platform body 2. One end of the line channel 202 is connected to the locking joint 203, and the other end of the line channel 202 is connected to the charging seat 8.

[0023] like Figure 5 As shown, in this embodiment, the sliding assembly includes a guide rail 101 fixed on the outside of the vertical pole 1 and a pulley 9 that slides with the guide rail 101. The pulley 9 is fixedly connected to the platform body 2 via a pulley frame 901. With the cooperation of the pulley 9 and the guide rail 101, the platform body 2 can be smoothly raised and lowered on the outside of the vertical pole 1.

[0024] The pole 1 used in this embodiment can generally be a street light pole 1, which is universal and extensive. A pole 1 that is compatible with agricultural pest control equipment can also be used, so that it is suitable for docking and charging of agricultural monitoring drones 3. A control cabinet 4 is fixed to the outside of the lower end of the pole 1, and the relevant control unit is set in the control cabinet 4 for controlling the relevant equipment and components in this charging apron.

[0025] like Figure 2-Figure 4 As shown, the charging seat 8 and the charging plug 301 are in contact with each other through conical surfaces to ensure the reliability of the docking between the two. The inner conical groove 802 of the charging seat 8 and the outer cone of the charging plug 301 are respectively provided with corresponding charging parts. The charging seat 8 is provided with an electromagnet 10 component for providing magnetic attraction to the charging plug 301. Specifically, a galvanized iron ring 304 is embedded in the bottom of the charging plug 301. Through magnetic adsorption with the electromagnet 10 component after power is turned on, the firmness of the charging plug 301 after connection is improved, thereby ensuring charging efficiency.

[0026] Further preferably, the charging portion of the outer cone is a plurality of conductive rings 303 arranged side by side along the axial direction, and the charging portion of the inner cone groove 802 is a plurality of conductive springs 805 arranged side by side along the axial direction. Specifically, the number of the conductive rings 303 and the number of the conductive springs 805 are both 5, which are used to connect the live wire, the neutral wire, the ground wire, the signal wire A and the signal wire B in sequence; Figure 4 As shown, one end of the conductive spring 805 is embedded in the charging seat 8 and electrically connected to the cable 701, and the other end of the conductive spring 805 is bent in an arc shape toward the inside of the charging seat 8. The charging seat 8 is provided with a mounting groove 803 connected to the inner conical groove 802, and the electromagnet 10 assembly includes an electromagnet 10 located in the mounting groove 803 and an elastic member for connecting the electromagnet 10 and the bottom of the mounting groove 803; since the charging seat 8 and the charging part of the charging plug 301 adopt elastic contact, the conductive spring 805 will form an upward thrust on the outer cone of the charging plug 301. Under the adsorption connection between the electromagnet 10 and the charging plug 301, the elastic member pulls down the charging plug 301 to balance the above thrust. At this time, the conductive spring 805 is in interference contact with the conductive ring 303, so that the two can complete stable and precise docking, thereby further ensuring the stability of the charging transmission process.

[0027] In order to ensure the stability of the electromagnet 10 before and after the adsorption with the galvanized iron ring 304 of the charging plug 301 is completed, a through hole 804 is opened at the bottom of the mounting groove 803, and a guide sleeve 12 is fixed in the through hole 804. A guide shaft 1001 that matches the guide sleeve 12 is fixed at the bottom of the electromagnet 10. The elastic member is a tension spring 11 that is sleeved on the outside of the guide shaft 1001. The two ends of the tension spring 11 are fixedly connected to the electromagnet 10 and the guide sleeve 12 respectively.

[0028] A distance trigger module 201 is installed on the platform body 2. The distance trigger module 201 is communicated with the lifting mechanism via the control unit. The distance trigger module 201 is used to set the trigger distance starting from the platform body 2. When the drone 3 that needs to be charged enters the trigger distance, the distance trigger module 201 sends information to the control unit and controls the operation of the lifting mechanism. In this embodiment, the distance trigger module 201 can use a ToF sensor module to measure the distance to the drone 3 by calculating the round-trip time for photons to leave the sensor, be emitted to the drone 3, and be reflected back to the sensor. A photoelectric proximity sensor module can also be used to sense the distance between the drone 3 and the platform body 2.

[0029] An infrared receiving module 801 is provided on the outside of the charging seat 8, and an infrared transmitting module 302 is provided on the bottom of the drone 3. The infrared receiving module 801 is communicated with the electromagnet 10 component through the control unit. The infrared receiving module 801 is configured to receive infrared light emitted by the infrared transmitting module 302 and send a signal to the control unit. The control unit controls the operation of the electromagnet 10 component according to the received signal.

[0030] A spoke-type tension sensor is installed within the guide sleeve 12 and is in communication with the control unit. The spoke-type tension sensor is used to set a tension threshold. When the tension detected by the spoke-type tension sensor reaches the tension threshold, the control unit sends a signal, which controls the cable 701 to supply power to the charging station 8. The selection of these sensors enhances the control unit's precision in controlling the charging pad.

[0031] In order to ensure that the apron can still operate stably under complex outdoor environmental conditions and extend the service life of the equipment, such as Figure 1 As shown, a protective cover 13 is installed on the vertical pole 1. The protective cover 13 is located between the fixed pulley 6 and the guide rail 101, and the platform body 2 is located in the orthographic projection area of ​​the protective cover 13.

[0032] Charging the drone 3 using the above-mentioned lifting drone charging pad includes the following steps: S1. When the drone 3 needs to be docked, the platform body 2 senses the approach of the drone 3 through the distance trigger module 201, and the control unit controls the winch 5 in the lifting mechanism to release the line, driving the platform body 2 to descend to the required height. The drone 3 identifies the position of the platform body 2 and the charging seat 8 through the visual guidance system and lands. Specifically in the embodiment, an RTK precise positioning and visual guidance solution is adopted. RTK consists of a ground reference station and an airborne receiving module. The satellite signal received by the reference station is sent to the drone 3 in real time through a wireless communication network. The airborne receiver jointly solves the received satellite signal and the received reference station signal in real time to obtain the coordinate increment (baseline vector) between the reference station and the drone 3, thereby playing a role in guiding the aircraft over a large range; visual guidance is to install a high-definition camera on the platform body 2. When the drone 3 is within the field of view, the camera recognizes the characteristics of the drone 3, locks and tracks it, and outputs the offset of the drone 3 in real time until the drone 3 is accurately guided to land in a small range.

[0033] S2. The charging plug 301 at the bottom of the drone 3 is inserted into the inner conical groove 802 of the charging base 8. The outer cone of the charging plug 301 and the inner conical groove 802 of the charging base 8 cooperate to compensate for a certain range of docking deviation. At this time, the infrared receiving module 801 outside the charging base 8 receives the infrared light emitted by the infrared transmitting module 302 at the bottom of the drone 3, and the control unit controls the electromagnet 10 to be energized.

[0034] S3. The charging plug 301 at the bottom of the drone 3 continues to approach the electromagnet 10 and is attracted to the electromagnet 10 through the galvanized iron ring 304. The tension spring 11 is in a stretched state, generating a downward pulling force on the electromagnet 10 and driving the charging plug 301 to continue to move downward until the tension detected by the spoke-type tension sensor reaches the set tension threshold. At this time, the conductive rings 303 of the charging plug 301 maintain pressure contact with the conductive springs 805 of the charging seat 8, and the control unit controls the cable 701 to supply power to the charging seat 8 to complete the charging of the drone 3.

[0035] In order to protect the drone 3 during the charging process, the control unit controls the winch 5 in the lifting mechanism to reel in, driving the platform body 2 to rise below the protective cover 13. The present invention adopts an automatic lifting mechanism, which can automatically adjust the height of the platform body 2 according to the height requirements of the drone 3, thereby improving the flexibility and adaptability of the drone 3 docking; combined with advanced visual guidance technology and precise mechanical drive devices, it ensures that the drone 3 can quickly and accurately dock with the charging seat 8 during the landing process, reducing docking errors and improving charging efficiency.
