Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) station equipment technology, and specifically relates to an UAV station. Background Technology

[0002] With the development of drone technology as an unmanned aerial vehicle, drones are being used in various fields. A drone is a flight device that uses battery power to rotate multiple propellers to fly in the air. Drones are configured to fly in various modes based on the operation of a user's remote control.

[0003] Drones consume a lot of batteries, so they need to be charged for extended flight. Existing drone landing equipment uses visual beacon recognition or satellite positioning, which has low positioning accuracy and the beacons are easily interfered with by other light sources. Furthermore, drones only use GPS information to land at the drone station, which leads to the following problems: the resonance center between the drone station and the drone is not precisely aligned, thus reducing charging efficiency and reliability. The reduced charging efficiency and reliability also increase charging time, making automatic charging or battery replacement impossible. In addition, the onboard equipment is not easy to replace.

[0004] Therefore, a drone station is proposed to address the shortcomings of existing technologies. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this invention provides a drone station with a three-layer structure that houses the drone body, backup battery, and onboard equipment respectively; it supports automatic take-off and landing of the drone, automatic battery replacement, automatic battery charging and discharging management, and automatic replacement of onboard equipment; the overall design is simple, easy to control, and highly reliable.

[0006] The technical solution of this invention to solve the above-mentioned technical problems is as follows: This unmanned aerial vehicle (UAV) station includes an upper plate, a middle plate, and a bottom plate arranged sequentially from top to bottom for parking UAVs. The bottom plate is provided with multiple support columns for supporting the upper plate and the middle plate. The upper plate is provided with a circular groove. The middle plate is annular and has multiple charging compartments arranged circumferentially on it. The circular groove is provided with a positioning component for locating the location of the UAV for replacing the spare battery. The middle plate is provided with a battery driving component for moving the multiple charging compartments and a battery loading / unloading component for loading and unloading the spare battery of the UAV. The bottom plate is provided with multiple onboard equipment loading / unloading components for loading and unloading UAVs at intervals in the middle. The bottom plate is provided with a carrier laser transmitter for guiding the UAV to land accurately.

[0007] Beneficial effects: The three-layer structure houses the drone body, backup battery, and onboard equipment respectively; it supports automatic take-off and landing of the drone, automatic battery replacement, automatic battery charging and discharging management, and automatic replacement of onboard equipment; the overall design is simple, easy to control, and highly reliable.

[0008] Furthermore, the positioning assembly includes a bearing gear ring, a gear ring drive gear, a centering lever, and a lever drive servo. The bearing gear ring is rotatably disposed within the circular groove. The gear ring drive gear is disposed on the upper plate and meshes with the bearing gear ring.

A plurality of lever drive servos are circumferentially spaced at the bottom of the upper plate, and the output ends of the lever drive servos are drively connected to the centering lever.

[0009] The beneficial effect of adopting the above-mentioned further solution is that when the drone lands on the bearing gear ring, the servo motor is first driven by the lever to drive the centering lever to push the drone to the middle position, and then the bearing gear ring is driven by the gear ring to rotate so that the drone's battery compartment outlet is aligned with the position of the spare battery that can be replaced.

[0010] Furthermore, two sets of first laser ranging sensors are vertically installed inside the circular groove for detecting whether the drone is inside the station.

[0011] The beneficial effect of adopting the above-mentioned further solution is to accurately determine whether the drone has landed within the station.

[0012] Furthermore, the upper plate is equipped with a photoelectric sensor for locating the location where the drone can replace its battery.

[0013] The beneficial effect of adopting the above-mentioned further solution is to determine whether the drone has been rotated to the position for battery replacement.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the battery compartment drive motor drives the battery compartment drive wheel to rotate the battery compartment to the correct position where the drone needs to replace the spare battery.

[0016] Furthermore, the battery loading / unloading assembly includes a lifting motor, a battery loading / unloading bridge drive servo, a battery loading / unloading carrier bridge, a battery loading / unloading worm drive motor, a battery loading / unloading worm, a battery loading / unloading turbine, and a battery loading / unloading drive gear. A lifting motor worm is vertically arranged through the middle of the lifting motor. The lifting motor worm is fixedly mounted on the mounting plate via a mounting base. The lifting motor is fixedly connected to the battery loading / unloading bridge drive servo. The output end of the battery loading / unloading bridge drive servo is pivotally connected to the battery loading / unloading carrier bridge. Multiple sets of battery loading / unloading drive gears are spaced apart and parallel on the battery loading / unloading carrier bridge. The battery loading / unloading worm is located at the bottom of the battery loading / unloading carrier bridge. Each set of battery loading / unloading drive gears is connected via a rotating shaft. The rotating shaft has a battery loading / unloading turbine meshing with the battery loading / unloading drive gear. The battery loading / unloading worm drive motor for driving the battery loading / unloading worm is located at the bottom of the battery loading / unloading carrier bridge.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the height of the entire battery loading and unloading transport bridge is controlled by the lifting motor, and the battery loading and unloading worm gear drive motor drives the battery loading and unloading drive gear through the worm gear to load and unload the battery back and forth.

[0018] Furthermore, a first position alignment sensor is provided at the bottom front end of the battery loading and unloading transport bridge, and a first laser probe is provided at the center of the base plate to cooperate with the first position alignment sensor, ensuring that the battery loading and unloading transport bridge, the drone battery compartment, and the charging compartment are on the same straight line during battery disassembly. A second position alignment sensor is provided at the rear end of the battery loading and unloading transport bridge, and a second laser probe is provided at the bottom of the middle plate to locate the No. 0 battery compartment, ensuring that the battery loading and unloading transport bridge, the drone battery compartment, and the charging compartment are on the same straight line during battery installation.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the first position alignment sensor and the second position alignment sensor can accurately position the battery loading and unloading carrier bridge, the drone battery compartment and the charging compartment on the same straight line, regardless of the battery installation and removal process.

[0020] Furthermore, the loading and unloading airborne equipment assembly includes a tripod, bearing brackets, slide rails, rollers, a horizontal drive motor, a reducer, a horizontal drive gear, a rack, an airborne equipment drive connection assembly, a slide rail, an airborne equipment bracket, and an airborne equipment slide rail.

The horizontal drive gear meshes with the rack, which is fixed to the base plate. The top of the tripod is equipped with the airborne equipment bracket. One end of the airborne equipment bracket is provided with the airborne equipment slide rail for the passage of a rotating support on the UAV. The tripod is equipped with an airborne equipment drive connection assembly for engaging the rotating support and driving it to slide into the airborne equipment slide rail.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the airborne equipment is pushed and pulled by the airborne equipment drive motor under the tripod, and the tripod can move back and forth in the radial direction of the base plate to align with the drone mounting frame to realize the installation and unloading of equipment.

The push rod is fixedly provided with a hook for engaging the rotating bracket.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the back-and-forth movement of the push rod driven by the airborne equipment drive motor causes the rotating bracket at the bottom of the UAV to be engaged with the hook, thereby driving the rotating bracket in the airborne equipment slide, thus realizing the placement and unloading of the airborne equipment.

[0024] Furthermore, the top of the tripod is provided with a slide rail for guiding the airborne equipment, and the slide rail and the airborne equipment slide groove are on the same straight line.

[0025] The beneficial effect of adopting the above-mentioned further solutions is that they serve as a guide and facilitate accurate positioning. Attached Figure Description

Detailed Implementation

[0036] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0037] Example 1

[0038] like Figure 1-2This embodiment provides a drone station, including: an upper plate 1, a middle plate 2, and a bottom plate 3 arranged sequentially from top to bottom for parking drones 18. The bottom plate 3 is provided with multiple support columns 14 for supporting the upper plate 1 and the middle plate 2. The number of support columns 14 depends on the actual situation. The top of the support column 14 for fixing the middle plate 2 is fixedly connected to the bottom of the middle plate 2, and the top of the support column 14 for fixing the upper plate 1 is fixedly connected to the bottom of the upper plate 1. The upper plate 1 has a circular groove, and the middle plate 2 is annular. Multiple charging compartments 8 are arranged circumferentially on the layer plate 2. The battery compartment 18 is the location for storing and charging the batteries of the UAV station. It is a ring-shaped turntable structure with 16 battery charging slots around the ring turntable. Each slot has an independent charging and power management circuit. A maximum of 16 battery slots can be installed on the ring turntable. The ring design is adapted to the ring structure of the UAV station and can effectively utilize the station space. The ring turntable with an internal toothed ring is driven to rotate by a stepper motor gear. It selects empty slots to store the UAV's battery or selects fully charged batteries for the UAV to use. The control is simple and convenient. The circular groove is equipped with a positioning component for locating the position of the UAV 18 to replace the spare battery 20. The middle layer plate 2 is equipped with a battery driving component 10 for moving the multiple charging compartments 8 and a battery loading and unloading assembly 11 for loading and unloading the spare battery 20 of the UAV 18. Multiple onboard equipment loading and unloading assemblies 15 for loading and unloading the onboard equipment of the UAV 18 are arranged circumferentially at intervals on the middle part of the bottom plate 3.

[0039] Preferably, in this embodiment, the positioning component includes a bearing gear ring 4, a gear ring drive gear 5, a centering lever 6, and a lever drive servo 7. The bearing gear ring 4 is rotatably disposed in the circular groove, and the gear ring drive gear 5 is rotatably disposed on the upper plate 1. The gear ring drive gear 5 is meshed with the bearing gear ring 4, and the gear ring drive gear 5 is driven by the output end of a gear ring drive motor disposed at the bottom of the upper plate 1. A plurality of lever drive servos 7 are circumferentially spaced at the bottom of the upper plate 1, and the output end of the lever drive servos 7 is driven by the centering lever 6. Two sets of first laser ranging sensors 13 for detecting whether the UAV is in the station are also vertically disposed in the circular groove. The upper plate 1 is provided with a photoelectric sensor 12 for locating the location of the UAV 18 for battery replacement.

[0040] The upper level of the station is equipped with a rotatable UAV-carrying gear ring 4. The gear ring has an outer gear ring, which is driven by a lever-driven servo motor 7 to drive the gear ring drive gear 5 to rotate, thereby adjusting the direction of the UAV. Two photoelectric sensors 12 on the upper plate 1 determine whether the UAV has rotated to the battery replacement position. Six centering levers 6, which are evenly distributed along the ring and controlled by servo motors, are installed below the gear ring 4 to adjust the position of the UAV to the center position of the station. Two sets of mutually perpendicular first laser rangefinder sensors 13 are used to determine whether the UAV 18 has entered the cabin and whether its position is centered.

[0041] Preferably, in this embodiment, as Figure 5 As shown, the battery drive unit 10 includes a battery compartment drive motor 101 and a battery compartment drive wheel 102. The battery compartment drive motor 101 is mounted on a mounting plate 9, and the mounting plate 9 is fixed on a support column 14. The output end of the battery compartment drive motor 101 is connected to the battery compartment drive wheel 102. The middle plate 2 is provided with an annular passive gear. The battery compartment drive wheel 102 is meshed with the passive gear. The battery compartment drive motor 101 drives the battery compartment drive wheel 102 to rotate the battery compartment to the correct position where the drone needs to replace the spare battery.

[0042] Preferably, in this embodiment, as Figure 6As shown, the battery loading / unloading assembly 11 includes a lifting motor 111, a battery loading / unloading bridge drive servo 112, a battery loading / unloading transport bridge 113, a battery loading / unloading worm gear drive motor 114, a battery loading / unloading worm gear 115, a battery loading / unloading turbine 116, and a battery loading / unloading drive gear 117. A lifting motor worm gear is vertically arranged through the middle of the lifting motor 111. The lifting motor worm gear is fixedly mounted on the mounting plate 9 via a mounting base plate 23. 111 is fixedly connected to the battery loading / unloading bridge drive servo 112. The output end of the battery loading / unloading bridge drive servo 112 is pivotally connected to the battery loading / unloading transport bridge 113. Multiple sets of battery loading / unloading drive gears 117 are spaced apart and parallel on the battery loading / unloading transport bridge 113. The bottom of the battery loading / unloading transport bridge 113 is provided with the battery loading / unloading worm gear 115. Each set of battery loading / unloading drive gears 117 is connected through a rotating shaft. The rotating shaft is provided with gears that mesh with the battery loading / unloading drive gears 117. The battery loading and unloading turbine 116 is combined with the battery loading and unloading carrier bridge 113. The bottom of the battery loading and unloading carrier bridge 113 is provided with a battery loading and unloading worm drive motor 114 for driving the battery loading and unloading worm 115. The front bottom of the battery loading and unloading carrier bridge 113 is provided with a first position alignment sensor 24. The center of the base plate 3 is provided with a first laser probe 17 for cooperating with the first position alignment sensor 24 to ensure that the battery loading and unloading carrier bridge 113, the battery compartment of the UAV 18 and the charging compartment 8 are on the same straight line during the battery removal process. The rear end of the battery loading and unloading carrier bridge 113 is provided with a second position alignment sensor 21. The bottom of the middle plate 2 is provided with a second laser probe 22 for locating the zero battery compartment to ensure that the battery loading and unloading carrier bridge 113, the battery compartment of the UAV 18 and the charging compartment 8 are on the same straight line during the battery installation process. The base plate 3 is also provided with a second laser range sensor 16 for locating the position of the UAV 18 to facilitate the installation and removal of the battery.

[0043] After the drone 18 is centered and the battery compartment is aligned with the battery replacement position, the battery loading and unloading carrier bridge 113 rotates. The battery loading and unloading bridge drives the servo motor 112 to control the rotation and aligns with the drone battery compartment through the first position alignment sensor 18. The first position alignment sensor 24 is the position alignment sensor between the battery loading and unloading carrier bridge 113 and the drone 18. It consists of a small laser emitter, a receiver and a reflector. The laser emitter emits a linear light source. The reflector design makes the light source reflect to the laser receiver positions of the drone 18 and the battery compartment, so that the battery loading and unloading carrier bridge 113, the drone battery compartment and the charging compartment 8 are on the same straight line. Subsequently, the lifting motor 111 of the battery loading and unloading transport bridge 113 controls the bridge body to dock with the UAV battery compartment, so that the battery loading and unloading drive gear 117 on the bridge meshes with the rack under the battery to pull the battery. The lifting motor 111 is a through lead screw stepper motor. After the battery is completely transported onto the bridge, the lifting motor 111 continues to control the bridge body to maintain the same height as the charging compartment so that the battery can be pushed into the charging position.

[0044] Conversely, during the battery installation process for the drone, the battery loading and unloading transport bridge rotates, driving the servo motor to rotate and aligning with the drone's battery compartment via the second position alignment sensor 21. Since the battery loading and unloading transport bridge 113, the drone's battery compartment, and the charging compartment 8 are on the same straight line, the bridge is aligned with the charging compartment. The lifting motor of the battery loading and unloading transport bridge controls the bridge body to maintain the same height as the charging compartment so that the battery can be pulled out from the charging position. The battery loading and unloading drive gear 117 drives the battery out of the compartment. After the battery is completely transported onto the bridge, the lifting motor 111 of the battery loading and unloading transport bridge 113 continues to control the bridge body to maintain the same height as the drone's battery compartment, and then pushes the battery into the drone, completing the battery installation operation.

[0045] Preferably, in this embodiment, the loading and unloading airborne equipment assembly 15 includes a tripod 151, bearing brackets 152, a slide rail 153, rollers 154, a horizontal drive motor 155, a reducer 156, a horizontal drive gear 157, a rack 158, an airborne equipment drive connection assembly, a slide rail 1511, an airborne equipment bracket 1512, and an airborne equipment slide rail 1513.

The triangular frame 151 is equipped with a horizontal drive motor 155 and a reducer 156. The output end of the horizontal drive motor 155 is connected to the reducer 156, and the output end of the reducer 156 is connected to the horizontal drive gear 157. The horizontal drive gear 157 is meshed with... The rack 158 is fixed to the base plate 3. The top of the tripod 151 is provided with the airborne equipment bracket 1512. One end of the airborne equipment bracket 1512 is provided with the airborne equipment slide groove 1513 for the rotating bracket 19 on the UAV 18 to pass through. The tripod 151 is provided with an airborne equipment drive connection assembly for engaging the rotating bracket 19 and driving the rotating bracket 19 to slide into the airborne equipment slide groove 1513. The drive connection assembly includes an airborne equipment drive motor, a push rod 159, and a hook 1510. The airborne equipment drive motor is mounted on the tripod 151. The output end of the airborne equipment drive motor is threadedly connected to the push rod 159. The push rod 159 is fixedly provided with a hook 1510 for engaging the rotating bracket 19. The top of the tripod 151 is provided with a slide rail 1511 for guiding the airborne equipment. The slide rail 1511 and the airborne equipment slide groove 1513 are on the same straight line.

[0046] The onboard equipment will be changed as the UAV 18 performs different tasks. For this purpose, the UAV station is designed with an onboard equipment loading and unloading component 15, which specifically involves the UAV station part and the UAV mounting part.

The airborne device is placed on the slope. The airborne device drive motor is located below the slope to control the extension and retraction of the push rod, just like a screw drive, which drives the hook 1510 to move back and forth, thereby hooking the rotating bracket 19 and placing the airborne device on it on the airborne device bracket 1512.
