Description

Technical Field

[0001] This invention belongs to the field of express delivery connection technology, and in particular relates to a drone express delivery connection device. Background Technology

[0002] With the rapid development of the logistics industry and the increasing maturity of drone technology, drone express delivery has gradually become an important development direction in the last-mile delivery field due to its advantages such as flexibility, efficiency, ability to overcome terrain limitations, and direct delivery to end users. Drone express delivery docking device is an electromechanical integrated device used to realize the automated transfer, temporary storage, and positioning docking of express parcels between drones and ground delivery nodes, mobile vehicles, or designated delivery points. Its core function is to solve problems such as accurate docking of drones at the last mile, safe handover of parcels, and adaptability to harsh environments. It is a key transit device in the drone logistics delivery system that connects air transport and ground last-mile delivery.

[0003] A search revealed a patent document with publication number CN113496576B, which discloses an intelligent drone delivery docking device and its application system. The device includes a slide rail assembly, a delivery locker assembly, and an integrated processor. The slide rail assembly comprises two vertically arranged sliding rods, pulleys, and a lifting motor. The pulleys are rotatably connected to the top of the sliding rods, and the lifting motor is fixed to the bottom of the sliding rods. The delivery locker assembly includes a mounting frame, multiple locker units, and a drive motor. One side of the mounting frame has a sliding groove that is slidably connected to the sliding rod. One end of a traction rope is fixed on the mounting frame, and the other end of the traction rope passes around the pulley and connects to the lifting motor. The multiple locker units are horizontally slidably connected to the mounting frame in upper and lower layers. Each locker unit has a door at the top and bottom, and a pickup door on one side of each layer. The integrated processor is installed on the inner wall of one of the locker units. An infrared detector is installed on the top locker unit, and a scanner is installed on the inner wall of each locker unit. The lifting motor, drive motor, door operator, and electromagnetic lock are all connected to the integrated processor via signals. While it can handle parcel delivery relatively well, the parcel box storage lacks organization. It can only receive single parcels and cannot automatically organize and stack multiple parcels. A large number of parcels piling up can easily cause chaos, not only taking up space but also increasing the workload for users to organize them later, and reducing the efficiency of receiving and picking up parcels. Summary of the Invention

[0004] The purpose of this invention is to address the problems mentioned in the background section by providing a drone delivery connection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions: A drone delivery docking device includes a window sill body, a storage component on the window sill body, and a drive component below the storage component; The storage assembly includes a recycling rack and a storage box. The recycling rack can drive the storage box to rotate, and the recycling rack can also drive the storage box to move. The storage box includes two opening and closing blades, two opening and closing frames, and an express delivery tray. The drive assembly can drive the two opening and closing frames to move relative to each other. The drive assembly can also drive the express delivery tray to move up and down. The opening and closing frames can control the opening and closing blades to open and close. Both of the opening and closing blades are equipped with electromagnetic dampers at the connection points with the storage box. The rotation angle of the opening and closing blades can be controlled by adjusting the current flowing into the electromagnetic dampers.

[0006] Preferably, the recycling rack includes a fixed bracket fixed to the main body of the windowsill, a hinge rotatably connected to the fixed bracket, two electric telescopic rods symmetrically rotatably connected to the two fixed brackets, two slide rails symmetrically fixedly connected to the hinge, the two electric telescopic rods rotatably connected to the two slide rails respectively, slide rail blocks slidably connected to the outer surface of the slide rails, the storage box fixedly connected to the slide rail blocks, and an electric telescopic rod 2 fixedly connected to the hinge, the telescopic end of the electric telescopic rod 2 fixedly connected to the storage box.

[0007] Preferably, when the electric telescopic rod is in the retracted state, the slide rail frame and the fixed bracket change from a vertical state to a parallel state.

[0008] Preferably, the drive assembly includes a motor fixed to the storage box, a limiting frame fixed to the storage box above the motor, a movable rod slidably connected inside the limiting frame, a threaded tube fixedly connected to the output end of the motor, a threaded bracket threadedly connected to the outer surface of the threaded tube, a top rod sleeved on the outer surface of the threaded tube, the top rod being fixedly connected to the threaded bracket, and two drive linkages symmetrically rotatably connected to the outer surface of the threaded bracket.

[0009] Preferably, the two movable rods are fixedly connected to the two opening and closing frames respectively, and the connection between the movable rods and the drive linkage is a rotatable connection.

[0010] Preferably, the protective component includes a sealing frame fixed to the storage box, the upper end of the sealing frame having a rectangular groove, the bottom wall of the sealing frame being fixedly connected to an electric telescopic rod three, the telescopic end of the electric telescopic rod three being fixedly connected to a sealing strip, an air pumping device being fixedly connected to the storage box, and an L-shaped pipe being fixedly connected between the air pumping device and the sealing frame.

[0011] Preferably, in the initial state, the sealing strip is attached to the inner wall of the rectangular groove.

[0012] Compared with existing technologies, the advantages of this drone delivery docking device are: 0. This invention sets up electromagnetic damping at the connection between the opening and closing leaf plate and the storage box, and controls the rotation angle of the opening and closing leaf plates on both sides by adjusting the magnitude of the current. This allows multiple packages to fall onto the package tray in sequence along the trajectory of the top, one side, and the other side. The packages can be stacked in an orderly manner without manual intervention, which not only saves storage space but also makes it easier for users to pick up and organize the packages, greatly improving the efficiency of package transfer and storage.

[0013] 1. This invention, through its protective components, effectively solves the problem of lightweight packages being easily blown off in windy weather. An air pump delivers air into the sealed frame, which, in conjunction with the electric telescopic rod and three-drive sealing strip movement, forms an air curtain. This airflow barrier counteracts wind interference, ensuring that the package remains stably placed on the opening and closing blades after the drone is released from its grip. This improves the reliability of package delivery in inclement weather and reduces the risk of damage or loss. The retraction of the electric telescopic rod in the recycling rack allows for easy storage and retrieval when the device is not in use, effectively reducing its footprint on windowsills, maintaining a clean and aesthetically pleasing home environment, and enhancing the device's spatial adaptability.

[0014] 2. In windy conditions, this invention can drive the threaded tube to rotate in the opposite direction by starting the motor, causing the threaded frame to move downwards. Through two drive linkages, two movable rods can be moved towards each other, causing the two opening and closing frames to also move towards each other. This can clamp the express boxes stacked in the storage box, preventing them from shaking in the wind and further ensuring the integrity of the items inside the express boxes.

[0015] 3. This invention achieves automatic separation and closure of the opening and closing frame through the linkage of the motor, threaded tube, threaded frame, and drive linkage of the drive component, thereby controlling the opening and closing of the opening and closing blades. Combined with the automatic folding and unfolding of the recovery frame, the entire process requires no manual operation, reducing labor costs and improving the automation level and ease of use of drone delivery. Moreover, it adopts a modular design, with the storage component, drive component, and protection component being independent and having a simple connection structure. If a component fails later, it can be disassembled and replaced individually without overall overhaul, resulting in higher maintenance efficiency. Attached Figure Description

[0019] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0020] Example: Refer to Figures 1 to 7 A drone delivery docking device includes a window sill body 1, a storage component 2 on the window sill body 1, and a drive component 3 below the storage component 2. The storage component 2 includes a recycling rack and a storage box. The recycling rack can drive the storage box to rotate and can also drive the storage box to move. The storage box includes two opening and closing blades 27, two opening and closing frames 20, and a delivery tray 29. The drive component 3 can drive the two opening and closing frames 20 to move relative to each other and can also drive the delivery tray 29 to move up and down. The opening and closing frames 20 can control the opening and closing of the opening and closing blades 27.

[0021] To further explain, the following settings are implemented to allow the express boxes to be automatically stacked within the storage box 26, such as... Figure 3 and Figure 4 As shown, electromagnetic damping is provided at the connection between the two opening and closing blades 27 and the storage box. The rotation angle of the opening and closing blades 27 can be controlled by adjusting the current flowing into the electromagnetic damping. The two electromagnetic dampings are in a stroke when the two resistances are the same, the resistance on one side increases and the damping on the other side increases. Specifically, due to the electromagnetic damping at the connection between the opening and closing leaf plate 27 and the storage box 26, when the first express box falls, the rotation amplitude of the two opening and closing leaf plates 27 is the same, and the express box will fall directly above the express tray 29. When the second express box falls, the rotation amplitude of one of the opening and closing leaf plates 27 is less than that of the other opening and closing leaf plate 27, and the express box will slide to one side onto the express tray 29. When the third express box falls, the rotation amplitude of the two opening and closing leaf plates 27 is reversed, so that the express box is tilted to the other side, which can automatically stack the express boxes. Compared to existing technologies, this new technology allows multiple packages to fall sequentially onto the package tray 29 along paths from directly above, to one side, and then to the other side. This achieves layered and orderly stacking of packages without human intervention, saving storage space and making it easier for users to pick up and organize their packages, thus significantly improving the efficiency of package delivery and storage.

[0022] To further explain, the following settings are implemented to facilitate the overall recycling of the device, such as... Figure 3 As shown, the recycling rack includes a fixed bracket 21 fixed to the main body 1 of the windowsill. A hinge 22 is rotatably connected to the fixed bracket 21. Two electric telescopic rods 23 are symmetrically rotatably connected to the two fixed brackets 21. Two slide rails 24 are symmetrically fixedly connected to the hinge 22. The two electric telescopic rods 23 are rotatably connected to the two slide rails 24 respectively. A slide rail block 25 is slidably connected to the outer surface of the slide rail 24. A storage box 26 is fixedly connected to the slide rail block 25. An electric telescopic rod 28 is fixedly connected to the hinge 22. The telescopic end of the electric telescopic rod 28 is fixedly connected to the storage box 26. When the electric telescopic rod 23 is in the retracted state, the slide rails 24 and the fixed bracket 21 change from a vertical state to a parallel state. It should be noted that when the two opening and closing leaf plates 27 rotate downward, the express boxes placed on them will fall onto the express tray 29. When the device is not in use, the two electric telescopic rods 23 can be shortened, so that the hinge 22 drives the slide block 25 and the storage box 26 to rotate downward until the top rod 36 rotates to be parallel to the main body of the windowsill 1, so that the storage box 26 used to store express packages can be recycled. Compared to existing technologies, when the electric telescopic rod 23 in the recycling rack retracts, it can drive the slide rail 24 from a state perpendicular to the fixed bracket 21 to a parallel state. Then, through the hinge 22 and the slide rail block 25, it can drive the storage box 26 to rotate downwards to be parallel to the main body of the windowsill 1, realizing the recycling and storage of the device when it is not in use. This effectively reduces the space occupied by the device on the windowsill, keeps the home environment clean and beautiful, and improves the space adaptability of the device.

[0023] To further explain, in windy conditions, the starting motor 31 can drive the threaded tube 34 to rotate in the opposite direction, causing the threaded frame 35 to move downwards. The two drive linkages 37 can drive the two movable rods 33 to move towards each other, causing the two opening and closing frames 20 to also move towards each other. This can clamp the express boxes stacked in the storage box 26, preventing them from being blown around by the wind inside the storage box 26.

[0024] To further explain, the following settings are made for the components within the drive unit, such as... Figure 5 As shown, the drive assembly 3 includes a motor 31 fixed on the storage box 26. Above the motor 31 is a limiting frame 32 fixed on the storage box 26. A movable rod 33 is slidably connected inside the limiting frame 32. A threaded tube 34 is fixedly connected to the output end of the motor 31. A threaded frame 35 is threadedly connected to the outer surface of the threaded tube 34. A top rod 36 is sleeved on the outer surface of the threaded tube 34. The top rod 36 is fixedly connected to the threaded frame 35. Two drive connecting rods 37 are symmetrically rotatably connected to the outer surface of the threaded frame 35. The two movable rods 33 are fixedly connected to the two opening and closing frames 20 respectively. The connection relationship between the movable rods 33 and the drive connecting rods 37 is a rotatable connection. Specifically, when the motor 31 is started, the motor 31 will drive the threaded tube 34 to rotate. During this process, due to the limiting of the threaded frame 35 by the drive linkage 37, the threaded tube 34 cannot drive the threaded frame 35 to rotate. As the threaded tube 34 rotates, it will drive the threaded frame 35 to move upward. During the upward movement of the threaded frame 35, it can drive the two movable rods 33 to move away from each other through the drive linkage 37. The movable rods 33 will drive the two opening and closing frames 20 to move away from each other, thereby releasing the support on the opening and closing blade 27.

[0025] To further explain, the following settings are implemented to prevent delivery boxes from falling in windy conditions, such as... Figure 6 As shown, the protective component 4 includes a sealing frame 41 fixed on the storage box 26. The upper end of the sealing frame 41 has a rectangular groove. The bottom wall of the sealing frame 41 is fixedly connected to an electric telescopic rod 42. The telescopic end of the electric telescopic rod 42 is fixedly connected to a sealing strip 43. In the initial state, the sealing strip 43 is attached to the inner wall of the rectangular groove. An air pumping device 44 is fixedly connected on the storage box 26. An L-shaped pipe 45 is fixedly connected between the air pumping device 44 and the sealing frame 41. It should be noted that when encountering windy weather, due to the different weights of the items in the express box, in order to prevent the express box from being blown off by the wind when the drone releases its grip on the express box, the air pumping device 44 is activated to draw air and transport it through the L-shaped tube 45 to the sealing frame 41 when the drone releases its grip on the express box. At this time, the electric telescopic rod 42 is activated to drive the sealing strip 43 to move downward. The air entering the sealing frame 41 will flow upward quickly, thus forming an air curtain, which can protect the express box placed on the opening and closing blade 27 and ensure that it will not be blown off by the wind. Compared to existing patents, the air pumping device 44 delivers air into the sealing frame 41, and the electric telescopic rod 42 drives the sealing strip 43 to move to form an air curtain. The airflow barrier counteracts wind interference, ensuring that the package remains stably placed on the opening and closing blade plate 27 after the drone is released from its grip. This significantly improves the reliability of package delivery in bad weather and reduces the risk of package damage or loss.

[0026] The functional principle of this invention can be explained through the following operation: After the drone carrying the package arrives above the device, it accurately places the package on the two opening and closing blades 27 of the storage component 2, and then releases the clamp. In response to the problem that packages of different weights are easily blown off in windy weather, the protective component 4 is activated simultaneously. The air pumping device 44 draws in outside air and accurately delivers it to the inside of the sealing frame 41 through the L-shaped pipe 45. At the same time, the telescopic end of the electric telescopic rod 42 drives the sealing strip 43 to move down along the inner wall of the rectangular groove of the sealing frame 41. The sealing strip 43, which was originally attached to the groove wall, is disengaged, opening up a smooth channel for air flow. The high-speed airflow surges upward in the sealing frame 41, forming a dense protective air curtain. The airflow barrier counteracts the wind interference, ensuring that the package remains stable during delivery and subsequent transfer. After the package is placed stably, the motor 31 outputs power, and its output end is fixedly connected to the threaded tube 34, directly driving the threaded tube 34 to rotate around its own axis. Since one end of the drive linkage 37 is rotatably connected to the threaded frame 35 and the other end is rotatably connected to the movable rod 33, and the movable rod 33 is slidably connected in the limiting frame 32, and the limiting frame 32 is fixed on the storage box 26, forming a rigid limiting constraint, so that the threaded tube 34 cannot drive the threaded frame 35 to rotate synchronously when it rotates, thus forcing the threaded frame 35 to move smoothly upward along the threaded structure of the threaded tube 34. When the threaded frame 35 moves upward, the drive linkage 37, which is symmetrically connected at both ends, transmits thrust, pushing the two movable rods 33 to slide in a direction away from each other along the guide trajectory of the limiting frame 32. The movable rod 33 is fixed to the opening and closing frame 20 as one piece, driving the two opening and closing frames 20 to separate synchronously. The opening and closing frame 20, which originally supported the opening and closing blade 27, is removed from the support position. Under the action of the weight of the package, the opening and closing blade 27 rotates downward around the connection with the storage box 26. Electromagnetic damping is provided at the connection between the opening / closing blade 27 and the storage box 26. By precisely adjusting the current supplied to the electromagnetic damping, the rotation angle of the opening / closing blades 27 on both sides can be precisely controlled, realizing automatic layered stacking of express packages. When the first express package is delivered, the same current is supplied to the electromagnetic damping on both sides, the resistance is consistent, and the rotation amplitude of the opening / closing blades 27 is exactly the same, so the express package falls precisely above the express tray 29. When the second express package is delivered, the current of the electromagnetic damping on one side increases and the resistance becomes stronger, while the other side maintains the original current and resistance, so that the rotation amplitude of the opening / closing blades 27 on both sides is different, and the express package slides to one side along the tilt direction. When the third express package is delivered, the current of the electromagnetic damping on both sides is reversed, the rotation amplitude is reversed, and the express package slides to the other side. The whole process does not require manual intervention. Through the linkage of mechanical structure and electromagnetic control, the express packages are stacked neatly, which greatly improves the connection efficiency. When the device completes the delivery or is idle, the electric telescopic rod 23 retracts, with its two ends rotatably connected to the fixed bracket 21 and the slide rail 24, respectively. The fixed bracket 21 is fixed to the windowsill body 1. The retraction force drives the slide rail 24 to rotate around the connection point with the fixed bracket 21, so that the slide rail 24 and the fixed bracket 21 smoothly change from the initial vertical state to the parallel state. The slide rail 24 is fixedly connected to the hinge 22, and the hinge 22 rotates synchronously with the slide rail 24. At the same time, the slide rail block 25 is slidably connected to the outer surface of the slide rail 24, and the slide rail block 25 is fixedly connected to the storage box 26. Under the rotational traction of the hinge 22 and the guiding action of the slide rail 24, the storage box 26 is driven to rotate downward until the storage box 26 is parallel to the windowsill body 1, completing the storage and recycling.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
