Description

Technical Field

[0001] This invention relates to the field of drone logistics delivery and intelligent terminal receiving equipment technology, specifically to a fully automated drone express delivery intelligent receiving terminal device suitable for indoor wall installation in homes, featuring retractable storage, adaptive landing, automatic alignment and clamping, interference-free pushing, and layered sealed storage. Background Technology

[0002] With the development of the low-altitude economy, drone delivery has become an important direction for last-mile logistics. However, the availability of terminal devices capable of automated in-home receiving has become a key bottleneck restricting the widespread adoption of this model. Existing parcel receiving devices are mostly single-function fixed storage boxes, which generally suffer from the following problems: a lack of a buffer receiving platform for precise docking with drones, resulting in poor delivery stability and packages easily falling or being damaged; a lack of automatic centering and sealing protection structures during parcel storage, making packages susceptible to wind, rain, and dust, and positional deviations affecting subsequent automated processing; the devices are typically single-compartment structures, unable to achieve multi-layered storage, insufficient capacity for continuously receiving multiple packages, and low space utilization; furthermore, the fixed overall structure prevents flexible adjustment of the receiving point based on the drone's hovering position, resulting in low levels of automation and intelligence, and failing to meet the practical needs of multi-batch, isolated storage. Summary of the Invention

[0003] The purpose of this invention is to provide a smart receiving terminal for drone express delivery, so as to solve the technical problems existing in the prior art, such as poor docking accuracy, lack of sealing protection, and inability to continuously and automatically store data.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a drone delivery intelligent receiving terminal, including a terminal body, wherein the improvement is that a telescopic slide rail device, an unfolding landing platform device, a clamping and sealing device, a pushing device and a layered storage device are integrated on the terminal body.

[0005] The telescopic slide rail device is used to drive the actuators installed at its ends to move back and forth between the indoor storage position and the outdoor working position that extends outdoors.

[0006] The deployable landing platform device is installed at the far end of the telescopic slide rail device and is used to deploy when working outdoors to form a stable receiving surface and passageway for drones to dock and form a package delivery opening.

[0007] The clamping and sealing device, installed below the deployment and landing platform, integrates bidirectional centering and clamping functions and port swing sealing functions. Its function is to perform bidirectional centering and clamping of packages falling into the receiving chamber, preventing interference with the delivery during the drone's flight. After the drone flies away and the device retracts into the chamber, the trapezoidal clamping plate loosens slightly. The rear sealing mechanism provides a seal, and when it is necessary to remove the package from the receiving chamber, it swings to open the passage.

[0008] The pushing device is installed below the clamping and sealing device and is used to smoothly and horizontally push the positioned package from the receiving chamber to the layered storage device at the rear of the terminal body after the sealing door is opened.

[0009] The layered storage device is located inside the terminal body and adopts a multi-layered tray vertical nesting arrangement. It is equipped with a drive system for overall lifting and independent layer lifting, which is used for the safe storage of multiple packages with vertical layering and independent locking.

[0010] As a further improvement to this invention, the telescopic slide rail device adopts two sets of three-stage telescopic structures symmetrically arranged on both sides. Through the nested cooperation of the inner, middle, and outer layers of slide rails, it achieves sequential and orderly extension and retraction. Four electric push rods are configured on both sides, which, through synchronous linkage with the control system, drive different levels of slide rails to extend or retract sequentially, thereby smoothly delivering the end effector to the outdoor working position or retracting it to the indoor storage position. This sequential extension and retraction method effectively increases the extension stroke while ensuring the structural rigidity and operational stability of the end effector in the long overhang state, overcoming the limitations of wall obstruction and providing reliable mechanical support for the precise docking and deployment of drones in open spaces.

[0011] As a further improvement of the present invention: the deployment and landing platform device adopts a symmetrical telescopic deployment structure with a lead screw and nut and a connecting rod drive. The drive motor drives the lead screw to rotate, causing the lead screw and nut to move back and forth along the axial direction, which in turn drives the landing platform plates on both sides to deploy synchronously in opposite directions or retract in opposite directions through the hinged connecting rod drive structure. A linear guide rail slider mechanism is provided at the bottom of the platform plate as a guide to ensure the smoothness and precision of the deployment and retraction actions.

[0012] As a further improvement of the present invention: In the clamping and sealing device, the bidirectional centering clamping mechanism consists of symmetrically arranged centering electric push rods and trapezoidal clamping plates. The push rods on both sides feed synchronously, driving the trapezoidal clamping plates to push the package bidirectionally without off-center load until the package is pushed to the preset center position, and then the reserved space is released. The port swing sealing mechanism consists of a sealing drive motor, a first synchronous wheel, a second synchronous wheel, a synchronous belt A, and a sealing door. The sealing drive motor drives the sealing door to swing around the rotating shaft, realizing the opening and sealing of the receiving chamber.

[0013] As a further improvement of the present invention: the pushing device adopts a linear pushing structure with a synchronous belt and two guide rods. The first and second guide rods are set in parallel to provide precise guidance for the dual-axis slider connector with a triangular push plate installed. The pushing motor drives the triangular push plate to move back and forth along the guide rod axis through synchronous belt B, smoothly pushing the package into the storage area.

[0014] As a further improvement to this invention: the layered storage device adopts a multi-layered independent storage tray structure arranged vertically in a nested configuration. The overall structure consists of an upper integrated rope lifting structure and a layered rope lowering structure, used to achieve continuous reception, layer-by-layer isolated storage, and sequential descent of multiple layers of packages. The upper integrated rope lifting structure is driven by a main hoist system to raise and lower the entire storage chamber, adapting to different retrieval heights and facilitating users to retrieve multiple stored packages at once. The layered rope lowering structure, through a winch and pulley system, drives each layer of storage trays to rise and fall independently, allowing each tray to descend one layer height, creating space for the next empty tray and achieving orderly layer-by-layer storage of multiple packages. Each layer of storage trays is also equipped with an electromagnetic lock to secure the nested storage trays layer by layer and release them sequentially, ensuring that only one layer is released at a time. The electromagnetic locks employ a power-off self-locking structure to ensure that the trays will not fall off in the event of an accidental power outage, guaranteeing storage safety.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects: This invention links a progressively extendable sliding rail device with a foldable, deployable landing platform device, enabling the entire execution unit—including a clamping and sealing device and a pushing device—to be smoothly delivered outdoors. This overcomes the physical obstruction of walls, achieving precise docking and delivery of drones in open spaces, significantly improving the adaptability and success rate of delivery. After delivery, the integrated clamping and sealing device automatically centers and seals the package, ensuring positional accuracy for subsequent pushing operations while effectively isolating external environmental interference. Combined with the dual-guide rod pushing mechanism of the pushing device, the package is smoothly transferred to the internal multi-layered storage unit. This layered storage unit utilizes an innovative dual-winch collaborative drive mode—"main hoisting system 609 overall lifting, hoisting machine layered independent material dropping"—and multi-point electromagnetic locks to achieve continuous, layered, independent, and sealed storage of multiple batches of express packages. The entire process, from receiving to warehousing, requires no manual intervention, and its automation level, operational reliability, and protection level are significantly superior to existing technologies.

Detailed Implementation

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. It should be noted that the described embodiments are only some embodiments of the present invention, and other implementations obtained based on the core concept of the present invention are all within the protection scope of the present invention.

[0025] In the description of this invention, it should be understood that the terms "front end," "rear end," "far end," "near end," "upper," "lower," "left," "right," "inner," and "outer," indicating orientation or positional relationships, are defined based on the orientation or positional relationships shown in the accompanying drawings and the actual state of the device when it is installed on the wall. Specifically, "front" or "far end" refers to the outdoor direction, and "rear" or "near end" refers to the indoor direction. These terms are used only for simplification and are not intended to require the invention to be constructed and operated in a specific orientation, nor should they be construed as limiting the invention.

[0026] Furthermore, the terms "first" and "second" are used only to distinguish similar components, such as "first electric actuator 203" and "second electric actuator 213," and do not indicate any specific order or importance. The terms "installation," "connection," and "fixing" should be interpreted broadly, and unless otherwise explicitly defined, they cover detachable or non-detachable connections achieved through conventional mechanical connection methods such as screws, welding, riveting, and snap-fitting, as well as indirect connections achieved through intermediate components.

[0027] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] Please also refer to Figure 1 and Figure 2 This embodiment provides a drone delivery intelligent receiving terminal, primarily for use in residential settings. The terminal body 101 is mainly installed on an indoor wall near a window and reliably fixed to the wall via a wall mounting bracket 104. The shell 102 of the terminal body 101 forms the load-bearing frame and external protective shell of the entire device. The terminal integrates five collaborative core devices: a telescopic slide rail device 201, a landing platform device 301, a clamping and sealing device 401, a pushing device 501, and a layered storage device 601. The landing platform device 301, clamping and sealing device 401, and pushing device 501 are integrated sequentially from top to bottom, forming a unified front-end execution assembly, which is fixed to the front end of the telescopic slide rail device 201. The layered storage device 601 is independently located in the rear space of the terminal body 101. When the terminal is not in operation, the telescopic slide rail device 201, together with its front-end actuator assembly, is completely retracted into the indoor side of the terminal body 101. At this time, the movable window sash 103 at the front of the terminal body 101 is closed. The device is compact and does not occupy indoor space.

[0029] Please refer to this carefully. Figure 3 The core function of the telescopic slide rail device 201 is to smoothly and with a large stroke reciprocate between the front-end receiving actuator and the outdoor working position. To achieve this goal, this solution adopts a strictly symmetrical dual-sided power drive and a three-stage slide rail progressive telescopic structure. Taking one side as an example, its structure includes a fixed base 202. A first electric push rod 203 is installed on the inner wall of the fixed base 202, and its cylinder tail is fixed. The output end of the push rod is rigidly connected to an L-shaped slide rail connecting plate 205 through a connecting seat 204. At the same time, the first set of outer slide rails 207 of the first set of three-stage telescopic slide rails 206 is fixedly installed on the outer wall of the fixed base 202. The side of the first inner slide rail 208 of the first group of three-stage telescopic slide rails 206 is locked to the outer side of the horizontal edge of the L-shaped slide rail connecting plate 205 by screws. When the first electric push rod 203 extends or retracts, its thrust acts directly on the L-shaped slide rail connecting plate 205, thereby causing the first inner slide rail 208 of the first group of three-stage telescopic slide rails 206 to slide relative to the first outer slide rail 207, completing the first stage of extension or retraction. Furthermore, on the inner side of the horizontal edge of the L-shaped slide rail connecting plate 205, the second outer slide rail 210 of the second group of three-stage telescopic slide rails 209 is fixedly installed. A U-shaped slide rail connecting plate 212 is fixedly installed on the second inner slide rail 211 of the second group of three-stage telescopic slide rails 209. A second electric push rod 213 is assembled inside the U-shaped slide rail connecting plate 212. The output end of the second electric push rod 213 extends backward and connects to the aforementioned L-shaped slide rail connecting plate 205. When the drone carrying the package arrives at the window, the system first controls the telescopic slide rail device 201. The four electric push rods on both sides move synchronously under the coordination of the control system. The extension process is carried out in two simultaneous steps: First, the first electric push rod 203 pushes the L-shaped slide rail connecting plate 205 and the entire second-stage assembly mounted on it forward. The travel in this stage mainly comes from the unfolding of the first set of three-stage telescopic slide rails 206. Second, the second electric push rod 213 uses the L-shaped slide rail connecting plate 205 as a fulcrum to push its own U-shaped slide rail connecting plate 212 and the end effector assembly forward. The travel in this stage comes from the unfolding of the second set of three-stage telescopic slide rails 209. Through the superposition of the two sets of three-stage slide rails, the device is compact in its retracted state, while when fully extended, it can achieve an effective working stroke far exceeding the wall thickness. The end effector assembly can extend through the open movable window sash 103 to the outside, ensuring the landing platform fully extends into the open outdoor space.

[0030] Please refer to this carefully. Figure 4The deployment and landing platform device 301 is mounted on the U-shaped slide rail connecting plate 212 and moves in and out together with the telescopic slide rail device 201. Its main body is a fixed frame 302 symmetrically arranged along the center line, and all components are mounted on this fixed frame 302. A drive motor 303 is mounted on one side of the fixed frame 302. The output shaft of the drive motor 303 is coaxially connected to a lead screw 305 arranged horizontally in the front-back direction via a coupling 304. The front end of the lead screw 305 is fixed to the fixed frame 302 via a bearing seat 306, allowing it to rotate freely. A lead screw nut 307 is threaded onto the lead screw 305; this nut cannot rotate but can only move axially along the lead screw 305. A connector 308 is fixed to the upper end of the nut, which is in turn fixedly connected to a slider 309 above it. Two parallel positioning optical axes 310 pass through both sides of the slider 309. The front and rear ends of the positioning optical axes 310 are fixed to the fixed frame 302 through optical axis seats A311, ensuring high-precision linear guidance of the lead screw nut 307 during movement. The connector 308 and the front end of the fixed frame 302 are respectively connected to a set of left-right symmetrical linkage transmission structures 312 through hinge pins. Specifically, each side has a structure consisting of two connecting rods hinged together. The outer ends of the linkage structures are hinged to a vertically set push plate 313. A landing platform plate 314 is fixed to the outer surface of the left and right push plates 313 with screws. The bottom of the landing platform plate 314 is equipped with a linear guide rail 315 slider pair arranged in the left-right direction as a guide. The guide rail slider 316 is installed on the upper surface of the U-shaped slide rail connecting plate 212. Once the drone reaches the window and hovers, the drive motor 303 rotates forward, and the lead screw 305 rotates, driving the lead screw nut 307 to move backward from its front limit position. The connecting piece 308 then moves backward, and through the linkage transmission structure 312, the backward pulling force is converted into a pushing force on both sides of the two push plates 313, driving the two landing platform plates 314 to smoothly unfold back-to-back along the bottom linear guide rail 315 until they reach the set rear position. At this point, the two landing platform plates 314 are fully unfolded, forming a flat and wide receiving surface, naturally exposing a rectangular delivery channel opening in the middle. When the package is delivered and needs to be returned indoors, the drive motor 303 reverses, and the lead screw nut 307 moves forward, pulling the two landing platform plates 314 together through the linkage transmission structure 312, achieving a folded-back design that significantly reduces the lateral dimensions for easy retraction.

[0031] Please combine Figure 5 and Figure 1The receiving housing 402 of the clamping and sealing device 401 is a box-shaped structure with a through-hole in the middle and openings at the top and rear. It is fixedly installed below the mounting frame 302 of the unfolding landing platform device 301. When the landing platform plate 314 unfolds, the package dropped by the drone passes through the central channel opening and falls directly into the inner cavity of the receiving housing 402. After the package falls in, two symmetrically installed centering electric push rods 403 on the left and right sides of the receiving housing 402 simultaneously push two trapezoidal clamping plates 404 towards the center. The trapezoidal inclined surfaces generate a guiding force on the package, pushing it to the geometric center of the receiving chamber without off-center loading, and applying a preset holding force to firmly clamp it. At the rear end of the receiving housing 402, a port swing sealing mechanism is provided. This mechanism includes a sealing drive motor 405, on the output shaft of which a first synchronous pulley 406 is mounted. The first synchronous pulley 406 transmits power to a second synchronous pulley 407 via a synchronous belt A408. The second synchronous pulley 407 is fixedly connected to a rotating shaft 409, on which a sealing door 410 is fixedly mounted. Throughout the entire process of receiving and centering the package, the sealing door 410 remains closed, tightly fitting against the rear end face of the receiving housing 402. When the entire mechanism retracts into the room and the pushing device 501 is ready to push the package out, the clamping and sealing device 401 will first perform a "slight loosening" action, that is, the centering electric push rods 403 on both sides will simultaneously retreat a small preset distance to release the strong pressure on the package, but the trapezoidal clamping plate 404 will still remain on both sides of the package to form a lateral limiting channel; then, the sealing drive motor 405 will start, and through the synchronous belt A408, it will drive the sealing door 410 to swing and rotate about 90 degrees around the rotating shaft 409 to open the rear channel.

[0032] Please combine Figure 6The pushing device 501 is installed below the base plate of the receiving housing 402 of the clamping and sealing device 401. Its structure includes a pushing motor 502, with a driving synchronous pulley 503 fixed on the output shaft of the pushing motor 502, and an idler pulley 504 at one end. A synchronous belt B505 is tensioned between the two. The lower end of a dual-axis slider connector 506 is clamped and fixed to one side of the synchronous belt B505, and a triangular push plate 507 is fixedly installed on the upper end of the connector. The body of the dual-axis slider connector 506 is slidably mounted on two parallel first guide rods 508 and second guide rods 509. The first guide rods 508 and second guide rods 509 are fixedly installed below the clamping and sealing device 401 by four sets of optical axis seats B510, ensuring that the two guide rods are parallel and stably arranged. When the sealed door 410 is opened, the push motor 502 starts, driving the dual-axis slider connector 506 to move from back to front along the guide rod via the synchronous belt B505. The triangular pusher plate 507 then pushes the package smoothly out of the receiving chamber, through the opening of the sealed door 410, and finally into the rear layered storage device 601. After pushing is complete, the push motor 502 reverses, bringing the triangular pusher plate 507 back to its initial rear position.

[0033] Please refer to this carefully. Figure 7The layered storage device 601 is the key to the continuous multi-parcel receiving and independent storage of this invention. It mainly consists of four parts: five-layer storage trays 602, 603, 604, 605, and 606; an upper integrated rope lifting structure; a layered rope lowering structure; and an electromagnetic lock 612. The five-layer storage trays are arranged in a vertical nesting and stacked manner. To manage the lifting of these trays, the device is equipped with two sets of rope drive systems. The first set is the upper integrated rope lifting structure, which consists of a main hoisting system 609, a steel wire rope 608, and guide rollers. The rollers are mounted on a fixed frame 607, and the steel wire rope 608 is connected to the frame of the uppermost tray or the entire tray group. When the user needs to retrieve all the stored parcels, the main hoisting system 609 can be controlled to lower the entire stack of trays to a position convenient for the user to retrieve the parcels. The second system is a tiered rope lowering structure, used to achieve independent lifting control of each pallet layer. Two winches 610 are fixedly installed on both sides of the base. Each winch 610 is wound with a steel wire rope. One end of the steel wire rope is fixed to the drum of the winch 610, and the other end extends downward, passes around the pulley block 611 installed under the bottom pallet, returns upward, and is finally fixed to the fixed base 202. Through this rope winding method of the moving pulley block, when the winch 610 winds up and unwinds the steel wire rope, it can control the pallet to fall slowly or rise smoothly with a small driving force. Working in conjunction with the tiered rope lowering structure are multiple electromagnetic locks 612 located on the left and right sides of the pallet group. They are installed on the base via U-shaped mounting parts 613. All electromagnetic locks 612 adopt a power-off self-locking design, that is, when no power is supplied, the locking tongue remains extended under the action of the internal spring, hooking or supporting the edge of the pallet to ensure absolute safety.

[0034] The automatic storage process of the layered storage device 601 is as follows: In the initial state, the top empty pallet is locked in the receiving position by the electromagnetic lock 612 above it, and the remaining empty pallets are stacked sequentially and locked below by their respective electromagnetic locks 612. When the first package is pushed onto the first layer storage pallet 602 by the pushing device 501, the winch 610 coordinates the release of the rope, causing the first layer storage pallet 602 carrying the package to fall smoothly a distance equal to the height of one layer. At this time, the winch 610 releases the rope to lower the second layer storage pallet 603 down to the receiving position, completing the automatic replacement of empty pallets. For subsequent packages, the above cycle of "receiving-unlocking-falling-replacement" is repeated, thus realizing the layered storage of multiple packages from bottom to top.

[0035] Based on the above description, the complete receiving process of the intelligent receiving terminal for drone express delivery of the present invention is as follows: Step S1, after the system receives the signal that the drone is about to arrive, the movable window 103 at the front of the main body 101 of the control terminal opens, and the four electric push rods 203 and 213 in the telescopic slide rail device 201 move in sync, driving the two sets of three-stage slide rails to extend step by step, and pushing the unfolding landing platform device 301, clamping sealing device 401 and pushing device 501, which are in the retracted state, as a whole, through the window and smoothly pushing them to the outdoor working position outside the window. Step S2, after the mechanism is in place, the drive motor 303 of the unfolding landing platform device 301 starts, driving the lead screw 305 to rotate, and through the lead screw nut 307 and the connecting rod transmission structure 312, the left and right landing platform plates 314 are smoothly unfolded to both sides to form a wide landing receiving surface, and at the same time the delivery channel in the middle opens. In step S3, the drone briefly docks on the landing platform 314 and delivers the package through the passageway into the receiving housing 402 of the clamping and sealing device 401 below. After delivery, the drone can fly away. Immediately, the centering electric push rods 403 on both sides of the clamping and sealing device 401 simultaneously push the trapezoidal clamping plates 404 to clamp the package in a non-eccentric, bi-directional centering manner, precisely fixing it in the center of the receiving chamber. In step S4, while maintaining a stable clamp on the package, the system performs the actions in reverse order: "platform retraction first, then slide rail retraction." The landing platform device 301 is unfolded and folded back, and the telescopic slide rail device 201 retracts the entire end effector assembly along with the package into the terminal body 101. The movable window 103 then closes, thus completing the safe transfer of the package from outdoors to indoors. In step S5, on the indoor side, the trapezoidal clamping plate 404 of the clamping sealing device 401 is slightly loosened to release the strong clamping while retaining the lateral limit; then, the sealing door 410 of the port swing sealing mechanism swings open, opening the rear channel; the push motor 502 of the push device 501 then starts, and the triangular push plate 507 smoothly pushes the package onto the empty pallet already positioned in the receiving position in the layered storage device 601. After pushing is completed, the sealing door 410 closes, and the triangular push plate 507 returns to its original position. In step S6, in the layered storage device 601, the electromagnetic lock 612 corresponding to the current layer pallet carrying the package is energized and unlocked, and the winch 610 releases the rope, causing the pallet to fall one layer height; the electromagnetic lock 612 corresponding to the empty pallet below is energized and unlocked, and descends under the drive of the winch 610, completing the empty pallet replacement. At this point, the system returns to the ready state to receive the next package.
