[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The drone nest in this solution is used in automated warehouses. Drones are used to automatically inspect goods, conduct inventory checks, and collect information within the warehouse. After completing their tasks, the drones can return to their nests autonomously or manually.

[0035] like Figures 1-6 As shown, this utility model provides a technical solution: a drone nest for an automated warehouse, including a mounting plate 1 and a controller. The mounting plate 1 is fixed to the top plate of the shelf by bolts 8. A connecting plate 2 is fixed to the side of the mounting plate 1, and a nest shell 3 is fixed to the side of the connecting plate 2. Figure 7 As shown, the drone nests are installed on the top panel of the outermost shelf. In this way, the nests are distributed on the shelves in different areas of the warehouse, and the drones can take off from the nest closest to the mission point, which greatly shortens the flight path and improves the response speed.

[0036] A stopping platform 5 is installed inside the nest shell 3. A lifting assembly is installed at the bottom of the stopping platform 5. The lifting assembly drives the stopping platform 5 to move vertically along the inner cavity of the nest shell 3. For example... Figure 4 As shown, the lifting assembly includes a threaded cylinder 601 movably connected to the bottom of the nest housing 3. A screw 602 fixed to the bottom of the landing platform 5 is movably screwed into the threaded cylinder 601. A first motor 603 electrically connected to the controller is fixed to the bottom of the nest housing 3, and the output end of the first motor 603 is fixed to the end of the threaded cylinder 601. Thus, when the drone returns to the nest, the controller controls the first motor 603 to start, and the first motor 603 drives the threaded cylinder 601 to rotate. Since the screw 602 is screwed to the threaded cylinder 601 and its top end is fixed to the landing platform 5, the rotation of the threaded cylinder 601 is converted into the vertical movement of the screw 602, thereby driving the landing platform 5 to rise to the top opening of the nest housing 3, making it convenient for the drone to land on the landing platform 5. After the drone is safely parked, the first motor 603 reverses, driving the landing platform 5 to descend into the nest housing 3, realizing the storage and protection of the drone.

[0037] Two vertical guide grooves 502 are provided on the inner walls of both sides of the nest shell 3, and guide blocks 503 matching the number of guide grooves are fixed on the side of the landing platform 5. The guide blocks 503 are embedded in the guide grooves and slide along them. In addition, the guide blocks 503 extend to the bottom of the vertical guide grooves 502. This not only effectively prevents the landing platform 5 from deviating or shaking during the lifting process and ensures operational stability, but also raises the landing platform 5 to a certain distance from the top of the nest shell 3, avoiding collision between the UAV and the top of the nest shell 3 when landing, and providing a safe space margin for the UAV to take off and land. At the same time, the cooperation between the guide blocks 503 and the vertical guide grooves 502 can also share the lateral force borne by the lifting assembly, reduce the wear between the threaded cylinder 601 and the screw 602, and extend the service life of the lifting mechanism.

[0038] like Figure 3 As shown, two landing gear placement slots 501 are provided on the top of the parking platform 5 for placing the two landing gears at the bottom of the UAV to prevent the UAV from shifting during parking or takeoff. A clamping component is provided in at least one landing gear placement slot 501 to stably clamp the two ends of the landing gear after the UAV lands.

[0039] like Figure 5 and Figure 6 As shown, the clamping assembly includes a socket cylinder 701 and a push rod 702. The push rod 702 is movably inserted into the socket cylinder 701. Push blocks 703 and pressure plates 711 made of elastic material are fixed to both ends of the push rod 702, respectively. The pressure plates 711 are preferably rubber plates. The push blocks 703 contact the inner wall of the socket cylinder 701. A spring 704 is fixed between the push blocks 703 and the inner wall of the side of the socket cylinder 701. A groove is formed on the plate of the stopping platform 5 that connects to the inner wall of the socket cylinder 701. The cavity is connected by a connecting hole 705, and the two connecting holes 705 are connected by a connecting pipe 706. An exhaust pipe 707 is fixedly connected to the body of the connecting pipe 706. A first solenoid valve 708 is connected to the body of the exhaust pipe 707. A hose 709 is fixedly connected to the body of the connecting pipe 706. A second solenoid valve is connected to the body of the hose 709. An air pump 710 is fixedly fixed to the top of the connecting plate 2, and the air pump 710 is connected to the hose 709.

[0040] Once the drone's landing gear is fully inserted into the placement slot, the controller activates the air pump 710 and opens the second solenoid valve. The gas generated by the air pump 710 enters the inner cavity of the socket cylinder 701 via the hose 709, connecting pipe 706, and connecting hole 705. This pushes the push block 703 to compress the spring 704, causing the pressure plate 711 to move inwards until it presses against the side of the landing gear, thus mechanically securing the drone. The activation time of the air pump 710 can be controlled by a preset program on the controller or detected by a pressure sensor located on the side of the pressure plate 711. Specifically, when the pressure sensor detects the pressure plate... When the pressure between the pressure plate 711 and the landing gear reaches a set threshold, which is obtained by those skilled in the art through a limited number of experiments or by calculation, the controller controls the air pump 710 to stop working and closes the second solenoid valve to ensure that the clamping force of the pressure plate 711 on the landing gear is moderate, which can fix the UAV without damaging the landing gear. When it is necessary to release the UAV, the second solenoid valve is closed and the first solenoid valve 708 is opened. The gas in the socket cylinder 701 is discharged through the exhaust pipe 707. The spring 704 resets and pushes the push block 703 and the pressure plate 711 to retract, releasing the clamping state.

[0041] In addition, a settling trough is provided on the top of the landing platform 5, and a wireless charging module 9 is fixed in the settling trough. The wireless charging module 9 is an electromagnetic induction charging unit based on the Qi or A4WP standard, which can charge the drone battery without contact after the drone is parked. The power can be replenished without human intervention, further improving the automation level of the drone nest.

[0042] To protect the drone from dust, a protective door assembly 4 is installed on the top of the drone's housing 3, wherein, for example... Figure 1 As shown, the protective door assembly 4 includes two swing doors 401. A drive unit is provided on the outside of the two swing doors 401, which drives the two swing doors 401 to move towards each other or away from each other.

[0043] Specifically, the driving component includes two first connecting seats 402 fixed to one side of the housing 3 and two second connecting seats 405 fixed to the other side of the housing 3. A double-ended lead screw 404 is movably connected between the two first connecting seats 402. A screw block 403 is fixed to one side of each of the two swing doors 401, and the two screw blocks 403 are respectively screwed to the two sides of the double-ended lead screw 404. A second motor is fixed to one side of the first connecting seats 402, and the output end of the second motor is fixed to the end of the double-ended lead screw 404. Furthermore, a guide rod 407 is fixed between the two second connecting seats 405, and a fixing block 406 is fixed to the other side of each of the two swing doors 401. The guide rod 407 is movably connected to the fixed block 406. When the drone needs to take off or land, the controller controls the second motor to start, and the second motor drives the double-ended lead screw 404 to rotate. Since the two lead blocks 403 are respectively screwed to the opposite threaded sections on both sides of the double-ended lead screw 404, the rotation of the double-ended lead screw 404 will cause the two lead blocks 403 to drive the swing door 401 to move in opposite directions or in opposite directions along the guide rod 407, thereby realizing the opening and closing of the protective door. When the drone is parked or charging, the swing door 401 moves in opposite directions to close, sealing the top of the drone housing 3, effectively preventing dust, moisture and debris from entering the drone housing, and protecting the drone and internal electronic components from environmental factors.

[0044] The working principle is as follows: the mounting plate 1 is fixed to the top plate of the shelf by bolts 8. When the drone needs to land, the controller first controls the second motor to start, which drives the double-headed screw 404 to rotate, causing the two swing doors 401 to move in opposite directions to open the protective door. At the same time, the first motor 603 starts, and through the cooperation of the threaded cylinder 601 and the screw 602, it drives the landing platform 5 to rise to the top opening of the nest shell 3. After the drone lands in the landing gear placement slot 501 of the landing platform 5, the air pump 710 starts and opens the second solenoid valve. The gas pushes the pressure plate 711 to clamp and fix the landing gear. Then the first motor 603 reverses, driving the landing platform 5 to descend into the nest shell 3. The second motor drives the swing doors 401 to move in opposite directions to close the protective door.
