Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a supply box configured with an deployable and clamping take-off and landing platform. Background Technology

[0002] With the development of drone technology, its applications are becoming increasingly widespread. For example, photography, which is commonly used by the general public, involves equipping rotary-wing drones with cameras and remotely controlling the drone's cruise via mobile phones while simultaneously taking pictures. For building inspection and maintenance, rotary-wing drones are equipped with extendable arms, and sometimes even suction cup structures are installed at the front of the extendable arms to attach them to the building surface and perform inspection work. For field environmental monitoring, cameras and other monitoring equipment are mounted on drones, which then fly to a preset location, land, and continuously monitor the operation before returning to base after completing the task.

[0003] A typical drone on the market includes a fuselage, frame, landing gear, towing arms, and rotors. It is equipped with a control system and power supply. The drone can be taken off remotely via remote control or mobile phone, then cruise to a preset location to perform hovering or ground operations, and land at the designated times for ground operations, completion of operations, or power supply replacement.

[0004] For example, Chinese patent document "Compressed Air Landing Unmanned Aerial Vehicle Landing Mechanism and Unmanned Aerial Vehicle, Publication No. CN219313065U" describes a landing gear comprising a closed assembly and at least three landing gear assemblies evenly distributed around the circumference of the unmanned aerial vehicle body. Another example is Chinese patent document "Pressure Rod Landing Unmanned Aerial Vehicle Landing Mechanism and Unmanned Aerial Vehicle, Publication No. CN219884123U," which describes a landing gear assembly comprising a pressure rod and a locking clamp. The pressure rod is slidably positioned below the unmanned aerial vehicle body, and the locking clamp is located around the pressure rod, capable of locking or releasing the pressure rod. Yet another example is Chinese patent document "Unmanned Aerial Vehicle Take-off and Landing Platform - Publication No. CN218489927U," which describes a method of fixing the unmanned aerial vehicle to the center of the shell through bidirectional centering.

[0005] As mentioned above, drone landing gear typically takes off and lands on a landing platform. Landing platforms are usually arranged in a fixed area, which results in a large storage volume. Utility Model Content

[0006] The purpose of this invention is to address the above-mentioned problems by providing a UAV resupply box, which arranges landing gear struts on the rotor guard frame, thereby increasing the surface area enclosed by the various landing gear struts and improving the stability of the landing gear structure.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] The drone supply box includes a box body and a liftable platform cover located at its upper opening. The liftable platform cover serves as a take-off and landing platform. The take-off and landing platform includes a platform body and a lifting mechanism. The lifting mechanism is located below the platform body to push the platform body up or down. The platform body includes two clamping plate assemblies, which are arranged laterally to form a platform in the unfolded state. Each clamping plate assembly includes a side plate and a middle plate. The inner lateral end of the side plate is rotatably connected to the outer lateral end of the middle plate. The take-off and landing platform also includes two pushing and rotating components. Each clamping plate assembly is equipped with... There is a push-rotating component, and the lifting component is connected to each clamping plate assembly to push it up or down. When the lifting component pushes the clamping plate assembly down, the push-rotating component can force the outer lateral end of the side plate and the inner lateral end of the middle plate to move backward and rotate a certain angle to the clamping state. When the lifting component pushes the clamping plate assembly up, the push-rotating component can force the outer lateral end of the side plate and the inner lateral end of the middle plate to move backward and rotate a certain angle to the unfolded state. The lateral width of the inner cavity of the box is smaller than the lateral width of the two clamping plate assemblies in the unfolded state.

[0009] The push-rotating component is a motor kit, including a motor and a synchronous gear. The side plate and the middle plate are connected by the synchronous gear in opposite directions so that the side plate and the middle plate can rotate synchronously in opposite directions. The motor drive is connected to the synchronous gear drive.

[0010] The distance between the rotating connecting shafts of the two clamping plate assemblies is the same as the distance between the landing feet of the drone to be landed, and the inner distance between the side plates and the middle plate of the clamping plate assembly is less than or equal to the width of the landing feet when clamped. Applied to drone landing, during descent, the ends of the two clamping plate assemblies furthest from the rotatable connecting shaft rotate laterally about the longitudinal rotatable connecting shaft, pushing the landing feet towards the rotatable connecting shaft and clamping them, thus achieving longitudinal centering and locking the landing feet and the drone.

[0011] When unfolded, the inner ends of the two middle plates are close to each other. Each middle plate has a protruding interlocking tooth on its top surface at its inner end. Several interlocking teeth are evenly distributed longitudinally on the corresponding middle plates. In the unfolded state, the interlocking teeth of the two middle plates are spaced apart, with the bottom surface of each tooth resting on the top surface of the opposite middle plate. This interlocking tooth structure at the inner ends of the two middle plates provides stable fixation and eliminates the need for internal support structures, thus increasing storage space and facilitating simplified support structures and lightweight design.

[0012] As mentioned above, the platform cover is divided into two rotatable clamping structures. Each part includes a side plate and a middle plate rotatably connected to it. Under the action of the lifting and pushing components, the lateral outer end of the side plate and the lateral inner end of the middle plate rotate a certain angle in the direction of movement and rearward. This allows it to switch between the unfolded state and the clamped state. In the unfolded state, the platform area is larger, which is conducive to ensuring the landing of the UAV. In the clamped state, the overall volume of the supply box is smaller, which is conducive to transportation.

[0013] Based on the aforementioned solution, in an improved solution, the clamping plate assembly further includes a partition plate. The inner lateral end of the side plate is rotatably connected to the outer lateral end of the partition plate, and the inner lateral end of the partition plate is rotatably connected to the outer lateral end of the middle plate. The lateral width of the partition plate is equal to the width of the landing gear feet of the UAV to be landed. Thus, through the partition plate arrangement, the distance between the side plate and the middle plate is adapted to the width of the landing gear feet, ensuring stable clamping of the landing gear feet without causing outward extrusion.

[0014] Based on the aforementioned solution, in an improved version, the UAV resupply box further includes a horizontal push rod and a clamp. The fixed end of the horizontal push rod is positioned at the clamping height within the box, and the clamp is positioned at the telescopic end of the horizontal push rod. The horizontal push rod can extend and retract longitudinally, and the clamp can grip or release the target object, thereby pushing the target object onto the take-off and landing platform when the platform is in the clamping state. This enables the operation of pushing the target object onto the take-off and landing platform.

[0015] Based on the aforementioned solution, in an improved version, the UAV resupply box also includes a material box and a slide. The fixed end of the horizontal push rod is arranged on the slide and can move left and right and up and down. The material box is below the clamped height position, and the opening of the material box faces the slide and the horizontal push rod. Several target objects are arranged sequentially inside the material box. In this way, the operation of taking out and pushing target objects to the take-off and landing platform can be realized.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. The drone of this utility model divides the platform cover into two rotatable clamping structures. Each part includes a side plate and a middle plate rotatably connected to it. Under the action of the lifting and pushing components, the lateral outer end of the side plate and the lateral inner end of the middle plate rotate a certain angle in the direction of movement and rearward, so that it can switch between the unfolded state and the clamped state. In the unfolded state, the platform area is larger, which is conducive to ensuring the landing of the drone. In the clamped state, the overall volume of the supply box is smaller, which is conducive to transportation.

[0018] 2. The two middle plates adopt an interlocking tooth structure on their inner sides, which can be stably fixed and saves the space for setting up a support structure in the inner cavity of the box. This can increase storage space and facilitate the simplification of the support structure and lightweight design.

[0019] 3. Through the arrangement of the side plates, the distance between the side plates and the middle plates is adapted to the width of the lifting feet, so as to stably clamp the lifting feet without causing outward squeezing, and avoid deviation from the preset height due to the clamping process.

[0025] Example 1

[0026] See Figure 1 and Figure 2 The supply box is defined to have a horizontal x and a vertical y, where xy is the horizontal direction and z is the vertical direction.

[0027] See Figures 1-17The UAV supply box of this embodiment 1 includes a box body 21 and a liftable platform cover arranged at its upper opening. The liftable platform cover is a take-off and landing platform. The take-off and landing platform includes a platform body and a lifting component. The lifting component is arranged under the platform body to push the platform body up or down. The platform body includes two clamping plate assemblies. The two clamping plate assemblies are arranged in sequence along the lateral direction to form a platform in the unfolded state. The clamping plate assemblies include a side plate 22 and a middle plate 23. The lateral inner end of the side plate 22 and the lateral outer end of the middle plate 23 are rotatably connected. The take-off and landing platform also includes two rotating components. Each clamping plate assembly is equipped with one rotating component. The lifting component is connected to each clamping plate assembly to push it up or down. When the lifting component pushes the clamping plate assembly down, the rotating component can force the lateral outer end of the side plate and the lateral inner end of the middle plate to move backward and rotate a certain angle to the clamped state. When the lifting component pushes the clamping plate assembly up, the rotating component can force the lateral outer end of the side plate and the lateral inner end of the middle plate to move backward and rotate a certain angle to the unfolded state. The lateral width of the inner cavity of the box is smaller than the lateral width of the two clamping plate groups in the unfolded state.

[0028] The drone body 1 includes a fuselage 15, a frame 11, landing gear (landing feet) 12, a support arm 13, and rotors 14. The rotor motors and drive shafts used have solid or hollow structures. The fuselage houses a lithium battery pack and a controller circuit board, connected and controlling the rotor's start and stop via standard cables. Both the drone body and its control system are existing technologies and will not be elaborated upon here; for example, DJI drones on the market; another example is the Chinese patent document "Landing Mechanism for a Press-Bar Landing Drone and Drone," publication number CN219884123U, where the landing gear assembly includes a pressing bar and a locking clamp. The pressing bar is slidably positioned below the drone body, and the locking clamp is located around the pressing bar, capable of locking or releasing it. The supply box structure is equipped with a lifting platform cover and uses a conveying mechanism to pick up target objects and transport them to the drone, where they are assembled with hook components, etc. This is also existing technology. This application improves the structure of the platform (landing platform) of existing supply boxes (such as supply parking areas) to enable unidirectional centering and clamping functions. Based on this, it utilizes existing conveying mechanisms to achieve a horizontal conveying example and existing hook assemblies to achieve an assembly example. The lifting components are existing lifting equipment; taking four lifting push rods (electric push rods) 24 as an example, they are equipped with a controller, which can be connected and controlled according to the instruction manual and the factory standard power data cable.

[0029] The side plate 22 and the middle plate 23 are connected by a hinge 221. The hinge shaft is connected to the telescopic end (top) of the lifting push rod through the top frame 222. The fixed end (bottom) of the lifting push rod is connected to a crossbar 241 and a vertical bar 242 for stable connection. This allows the side plate and the middle plate to be rotatably connected, and to push the side plate and the middle plate to rise or fall.

[0030] When unfolded, the inner ends of the two middle plates are close to each other. Each middle plate 23 has a protruding tooth 232 on its top surface at its inner end. Several teeth are evenly distributed longitudinally on the corresponding middle plates. When unfolded, the teeth of the two middle plates are spaced apart, with the bottom surface of each tooth resting on the top surface of the opposite middle plate. This interlocking tooth structure at the inner ends of the two middle plates provides stable fixation and eliminates the need for internal support structures, increasing storage space and facilitating simplified support structures and lightweight design. To optimize the interlocking effect, in a preferred embodiment, a tooth groove 231 is provided in the interlocking area. The tooth groove 231 fits the tooth 232, allowing the tooth to insert into the tooth groove during slow unfolding to achieve a tenon-and-mortise connection. Lateral positioning is also provided, improving connection stability. In other examples, as an alternative to supporting the inner side of the middle plate, a support plate can be installed below and connected to the top of the lifting push rod via a strut to achieve support and fixation. However, this solution will occupy internal space.

[0031] The rotating component is a passive, non-driven component, specifically a limiting frame, including an inner limiting frame 25 and an outer limiting frame 251. The inner and outer limiting frames 25 and 251 extend longitudinally and are arranged laterally at a certain distance to form a U-shaped clamping structure. The rotating connecting shaft between the side plate 22 and the middle plate 23 is directly above the center of the clamping position of the limiting frame on the same side. Its bottom side is connected to the inner wall of the housing, and its top surface presses against the bottom surface of the side plate and the middle plate, clamping them towards the top. When the lifting component pushes the clamping plate assembly down to the clamping height, the pressing action of the outer limiting frame 251 and the inner limiting frame 25 gradually approaches the lateral outer end of the side plate and the lateral inner end of the middle plate, forcing the lateral outer end of the side plate and the lateral inner end of the middle plate to move backward and rotate a certain angle to the clamping state; thus, it has the function of clamping the lifting feet. When the lifting component pushes the clamping plate assembly to rise and extend to the unfolded state, the pressing force of the outer and inner limiting frames gradually moves away from the lateral outer end of the side plate and the lateral inner end of the middle plate, forcing the lateral outer end of the side plate and the lateral inner end of the middle plate to move backward and rotate a certain angle to the unfolded state; thus, it has the function of serving as a lifting platform.

[0032] To apply the clamping function, the position of its rotating connecting shaft needs to be selected, i.e., the hinge position needs to be defined. This application mainly applies it to UAV landing. Therefore, the distance between the rotating connecting shafts of the two clamping plate assemblies is the same as the distance between the landing feet of the UAV to be landed. In this way, for a conventional four-legged structure, the two rotatable side plates and the middle plate can respectively adapt to and define the landing feet on both sides. Moreover, the inner distance between the side plates and the middle plate of the clamping plate assembly in the clamped state is less than or equal to the width of the landing foot. Thus, after rotating and contracting at a certain angle, the landing foot can be firmly clamped. It can be seen that when applied to UAV landing, during descent, the ends of the two clamping plate assemblies furthest from the rotatable connecting shaft rotate in the lateral direction of the rearward movement around the longitudinal rotatable connecting shaft, pushing the landing foot towards the rotatable connecting shaft and clamping the landing foot, achieving longitudinal centering and locking of the landing foot and the UAV.

[0033] During use, the descent process is as follows: In the initial unfolded state, the angle between the top surfaces of the side panel and the middle panel is 180°. The lifting push rod is activated to initiate the descent, causing the side panel and middle panel to descend. The outer lateral end of the side panel rests against the side wall of the housing, and thus, as it descends, it gradually rotates towards its top surface until its end enters the housing. Then, the side panel and middle panel contact the outer and inner limit frames respectively. The lifting push rod continues to descend, and the bottom surfaces of the side panel and middle panel, under the influence of the outer and inner limit frames, gradually rotate towards their top surfaces. Then, as the lifting push rod continues to descend, the angle between the top surfaces of the side panel and the middle panel gradually decreases (from 180° to 0°) until the top surfaces of the side panel and the middle panel reach the clamping position to clamp the lifting feet. Conversely, during the ascent process, the side panel and middle panel gradually unfold from the clamped state to the unfolded state, and the angle between the top surfaces of the side panel and the middle panel gradually increases from near 0° to 180°.

[0034] As mentioned above, the platform cover is divided into two rotatable clamping structures. Each part includes a side plate and a middle plate rotatably connected to it. Under the action of the lifting and pushing components, the lateral outer end of the side plate and the lateral inner end of the middle plate rotate a certain angle in the rearward direction, thus allowing it to switch between the unfolded state and the clamped state. In the unfolded state, the platform area is larger, which is conducive to ensuring the landing of the UAV. In the clamped state, the overall volume of the supply box is smaller, which is conducive to transportation. Figure 10 As shown, surface p is the area of ​​the platform required in the conventional unfolded state. That is, within the error range, the center of surface p is selected for landing, and the platform can land in this area. Since this application can cover surface p in the unfolded state, boxes of different specifications smaller than the area of ​​surface p can be designed as needed.

[0035] Example 2

[0036] Based on the aforementioned Embodiment 1, this Embodiment 2 is an improvement to assemble the target object by horizontal transport, as detailed below.

[0037] See Figures 1-17 The UAV supply box in this embodiment 2 also includes a horizontal push rod 31 and a clamp 32. The fixed end of the horizontal push rod 31 is arranged at the clamping height position inside the box body 21, and the clamp 32 is arranged at the telescopic end of the horizontal push rod 31. The horizontal push rod 31 can extend and retract longitudinally, and the clamp 32 can clamp or release the target object 35 so as to push the target object to the take-off and landing platform when the take-off and landing platform is in the clamping state. The conveying mechanism is illustrated using a horizontal push rod (electric push rod) as an example, and the clamp is illustrated using an electromagnetic clamp as an example. For example, in Chinese patent document "Electromagnetic Clamping Device, Publication No. CN200963761," the moving iron and fixed iron are attracted to clamp the lower pressure rod placed between them. Furthermore, the contact surfaces of the moving iron and fixed iron can be designed with an arc shape to increase the contact area and improve the clamping effect. Similarly, in Chinese patent document "Electromagnetic Clamping Device, Publication No. CN205600748U," the upper and lower clamping plates approach each other to clamp the lower pressure rod placed between them. Again, the contact surfaces of the upper and lower clamping plates can be designed with an arc shape to increase the contact area and improve the clamping effect. Existing components can be directly applied to this application, and will not be elaborated further here. In this way, the horizontal pushing of the target object to the lifting platform can be achieved.

[0038] Example 3

[0039] This embodiment 3, based on the aforementioned embodiment 2, has the function of storing and retrieving target objects. For other details not covered, please refer to the aforementioned embodiments 1 and 2.

[0040] See Figure 1 and Figure 17The UAV supply box in this embodiment 3 also includes a material box 34 and a slide table 33. The fixed end of the horizontal push rod 31 is arranged on the slide table and can move left and right and up and down. The material box 34 is below the clamping height position. The opening of the material box 34 faces the slide table 33 and the horizontal push rod 31. Each cell 341 in the material box 34 is arranged with several target objects 35. Among them, there are loading assemblies in UAV parking and supply warehouses, which can be fixed by hook components, etc. The slide table is also an existing component, namely a multi-axis linear module slide table, such as the two-cycle slide table FSL120XY-H2 of Fuyu Technology. The material box adopts a conventional open limit box as an example to pull out the target objects placed in the recessed groove. Existing components can be directly applied to this application, and will not be described in detail here. As shown in the figure, the top of the target object is equipped with a clamping section 351 and a hanging hole 352. The horizontal push rod extends outward into the material box, and once in position, the clamp grips the target object. Then, the slide rises to a certain height (e.g., 5cm) to pull out the target object. Next, the horizontal push rod retracts the discharge box. Then, the slide rises and moves left and right to the preset longitudinal center line and preset hanging height. Finally, the horizontal push rod extends outward to convey the target object to the hook assembly 16. The hook assembly hooks into the hanging hole to complete the assembly. Then, the clamp is released, and the horizontal push rod retracts, completing the assembly process. This allows for the removal and pushing of the target object to the lifting platform. Of course, other conveyor mechanisms such as belt conveyors and chains are not features of this application and will not be described in detail here.

[0041] Example 4

[0042] The difference between this embodiment 4 and the aforementioned embodiments 1-3 is that a spring is used as a pushing component to enable it to have an elastic contraction and clamping function. For details not covered, please refer to the aforementioned embodiments 1-3.

[0043] The aforementioned embodiments 1-3 use a limiting frame as a pushing and turning component. In the unfolded state, the side plate relies on its own weight to press against the side wall of the box. There is no locking and stopping structure, so there may be a phenomenon of being blown up and shaking in strong winds.

[0044] See Figure 18 and Figure 19In the supply box of this embodiment 4, the push-rotating component is a passive push-rotating component without driving force, specifically a spring, including an inner spring 25a and an outer spring 251a. Two or more inner springs are arranged sequentially along the longitudinal direction. As shown in the figure, taking two as an example, the upper end of the inner spring is hinged to the middle plate, and the lower end of the inner spring is hinged to a certain height below the middle plate. Two or more outer springs are arranged sequentially along the longitudinal direction. As shown in the figure, taking two as an example, the upper end of the outer spring is hinged to the side plate, and the lower end of the outer spring is hinged to a certain height below the side plate. The upper end of the spring is connected to the side plate and the middle plate, while the lower end of the spring is connected to the side wall of the box body through a bracket. When the lifting mechanism pushes the clamping plate assembly downwards to the clamping state, the outer and inner springs are compressed, creating a restoring force that forces the lateral outer end of the side plate and the lateral inner end of the middle plate to rotate backwards by a certain angle to the clamping state. When the lifting mechanism pushes the clamping plate assembly upwards to the unfolded state, the outer and inner springs are stretched, creating a restoring force that forces the lateral outer end of the side plate and the lateral inner end of the middle plate to rotate backwards by a certain angle to the unfolded state. The lifting push rod rests on the middle of the top frame 222a. Thus, in the unfolded state, the restoring force generated by the stretched springs pulls down and presses the lateral outer end of the side plate and the lateral inner end of the middle plate together, improving the stability of the unfolded state.

[0045] Example 5

[0046] This embodiment 5, based on the aforementioned embodiments 1-4, has a structure that improves the clamping effect between the side plate and the middle plate. For details not covered, please refer to the aforementioned embodiments 1-4.

[0047] The side plate and the middle plate are rotatably connected. If the gap is too small, it will cause a sharp corner clamping phenomenon, which may cause the landing feet to be squeezed outward, resulting in a deviation from the preset height when the drone is clamped. If the gap is too large, it will cause the drone to get stuck in the gap when moving back to center, which may cause forced clamping and damage to the landing feet, or even cause the landing feet to fall into the gap, resulting in a height deviation.

[0048] For this reason, see Figures 20-27 In the supply box of this embodiment 5, the clamping plate assembly also includes a partition plate 22b. The inner lateral end of the side plate is rotatably connected to the outer lateral end of the partition plate, and the inner lateral end of the partition plate is rotatably connected to the outer lateral end of the middle plate. Referring to the aforementioned embodiments 1-4, a partition plate is provided between the side plate and the middle plate. The side plate and the partition plate are connected by hinges, and the partition plate and the middle plate are also connected by hinges. Specifically, for application to UAVs, the lateral width of the partition plate is equal to the width of the landing gear feet of the UAV to be landed. Thus, through the partition plate arrangement, the distance between the side plate and the middle plate is adapted to the width of the landing gear feet to stably clamp the landing gear feet without causing outward extrusion.

[0049] Example 6

[0050] The difference between this embodiment 5 and the aforementioned embodiments 1-5 is that it uses a motor as a rotating component, making its rotation control more proactive.

[0051] See Figures 20-27 In the supply box of this embodiment 6, the push-rotating component is a driven, active push-rotating component, specifically a motor assembly, including a motor 26 and a synchronous gear 27. The side plate and the middle plate are connected by the synchronous gear in opposite directions so that the side plate and the middle plate can rotate synchronously in opposite directions, and the motor transmission is connected to the synchronous gear transmission. The rotational connection between the side plate and the middle plate is achieved by a long rotating shaft with bearings. Gear slots 22a1 and bearing slots 22a2 are opened on the side plate a 22a. The long rotating shaft is fixed to the side plate by a clamp 272, and the bearing seat 273 is fixed to the side plate 22b. The long rotating shaft 271 is rotatably connected to the bearing seat by a bearing 274. Similarly, the side plate 22b and the middle plate 23a are assembled. The synchronous gears 27 of the two long rotating shafts are connected by synchronous opposite-direction rotational meshing. The motor 26 is bolted to the plate-shaped top frame b 222b. It is controlled independently from the lifting push rod. The rotation control is performed by the motor, which allows for more active control of the rotation of the side plate and the middle plate. In addition to being able to rotate the side plates and middle plates during ascent or descent, just like a passive pusher, the motor kit can also rotate the side plates and middle plates before descent. For example, in windy weather, when a drone needs to be clamped quickly after landing, starting the motor directly can achieve the clamping purpose faster.

[0052] Example 7

[0053] The difference between this embodiment 7 and the aforementioned embodiment 6 is that it adopts a pin-shaft rotating connection structure. For details not covered, please refer to the aforementioned embodiments 1-6.

[0054] See Figure 28 In this embodiment 7, the supply box is rotatably connected using a short pin 271a. For the connection of bearings and other components, please refer to the foregoing.

[0055] Example 8

[0056] The aforementioned UAV supply box solutions in Embodiments 1-7 include a take-off and landing platform solution. This Embodiment 8 provides a brief description of this solution. For any further details, please refer to Embodiments 1-7.

[0057] See Figures 1-28The lifting platform of this embodiment 8 includes a platform body and a lifting component. The lifting component is arranged under the platform body to push the platform body up or down. The platform body includes two clamping plate assemblies, which are arranged in sequence along the lateral direction to form a platform in the unfolded state. It also includes two pushing components, each clamping plate assembly is equipped with one pushing component. The clamping plate assembly includes a side plate and a middle plate. The lateral inner end of the side plate and the lateral outer end of the middle plate are rotatably connected. The pushing component is arranged below the clamping plate assembly. The lifting component is connected to each clamping plate assembly to push it up or down. When the lifting component pushes the clamping plate assembly down, the pushing component can force the lateral outer end of the side plate and the lateral inner end of the middle plate to move backward and rotate a certain angle to the clamped state. When the lifting component pushes the clamping plate assembly up, the pushing component can force the lateral outer end of the side plate and the lateral inner end of the middle plate to move backward and rotate a certain angle to the unfolded state.

[0058] The distance between the rotating connecting shafts of the two clamping plates is the same as the distance between the landing feet of the drone to be landed, and the distance between the inner sides of the side plates and the middle plate of the clamping plates is less than or equal to the width of the landing feet when they are clamped.

[0059] In one specific example, the pusher is a motor assembly, including a motor and a synchronous gear. The side plate and the middle plate are connected by the opposite rotational meshing of the synchronous gear so that the side plate and the middle plate can rotate synchronously in opposite directions, and the motor drive is connected to the synchronous gear drive.

[0060] In a specific example, the pusher is a limiting frame, including an inner limiting frame and an outer limiting frame. The inner and outer limiting frames extend longitudinally and are arranged laterally at a certain distance to form a U-shaped clamping structure. The rotational connection shaft between the side plate and the middle plate is directly above the center of the clamping position of the limiting frame on the same side. When the lifting component pushes the clamping plate assembly down to the clamping height, the pressing force of the outer and inner limiting frames gradually approaches the lateral outer end of the side plate and the lateral inner end of the middle plate, forcing the lateral outer end of the side plate and the lateral inner end of the middle plate to move backward and rotate a certain angle to the clamping state. When the lifting component pushes the clamping plate assembly up to the unfolded state, the pressing force of the outer and inner limiting frames gradually moves away from the lateral outer end of the side plate and the lateral inner end of the middle plate, forcing the lateral outer end of the side plate and the lateral inner end of the middle plate to move backward and rotate a certain angle to the unfolded state.

[0061] In a specific example, the pusher is a spring, including inner springs and outer springs. Two or more inner springs are arranged longitudinally, with the upper end of the inner spring hinged to the middle plate and the lower end of the inner spring hinged to a certain height below the middle plate. Two or more outer springs are arranged longitudinally, with the upper end of the outer spring hinged to the side plate and the lower end of the outer spring hinged to a certain height below the side plate. When the lifting component pushes the clamping plate assembly downward to the clamping state, the outer and inner springs are compressed to form a restoring force, forcing the lateral outer end of the side plate and the lateral inner end of the middle plate to move backward and rotate a certain angle to the clamping state. When the lifting component pushes the clamping plate assembly upward to the unfolded state, the outer and inner springs are stretched to form a restoring force, forcing the lateral outer end of the side plate and the lateral inner end of the middle plate to move backward and rotate a certain angle to the unfolded state.

[0062] In a specific example, the clamping plate assembly also includes a partition plate, wherein the inner lateral end of the side plate is rotatably connected to the outer lateral end of the partition plate, and the inner lateral end of the partition plate is rotatably connected to the outer lateral end of the middle plate; wherein the lateral width of the partition plate is equal to the width of the landing gear landing feet of the UAV to be landed.

[0063] In a specific example, the transverse inner ends of the two middle plates are close to each other in the unfolded state. The top surface of the transverse inner end of each middle plate is provided with a tooth protruding from its end. Several teeth are evenly distributed longitudinally on the corresponding middle plates. The teeth of the two middle plates are arranged alternately in the unfolded state, and the bottom surface of the tooth rests on the top surface of the opposite middle plate.

The take-off and landing mechanism of the UAV in the above embodiments is mainly applied to UAVs, but it is also applicable to other devices used in the same / equivalent scenarios.
