Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicles (UAVs) and mechanical dogs, and in particular relates to a base station capable of docking UAVs and mechanical dogs. Background Art

[0002] The accelerated pace of urbanization and people's faster pace of life have placed higher demands on the efficiency and convenience of logistics and distribution. This is particularly true in the field of medical supply distribution, such as delivering medicines and medical devices from hospitals to patients' homes. Fast, accurate, and safe delivery methods are crucial for patient treatment and recovery. However, traditional logistics and distribution methods face numerous challenges. The "last mile" of logistics distribution—the distance from the distribution center to the end user—is often delayed due to traffic congestion, high labor costs, and low delivery efficiency. This problem is particularly prominent in older communities, remote areas, or areas with inconvenient transportation. The delivery of medical supplies, such as medicines and first aid supplies, requires not only swift delivery but also guaranteed safety and integrity. Traditional manual delivery methods can lead to errors or delays due to human error, compromising patient treatment outcomes. Drones, as an emerging logistics and distribution tool, offer speed, flexibility, and efficiency, effectively addressing the delivery challenges caused by urban traffic congestion. However, drones have limited endurance and payload capacity, typically limiting them to shorter delivery distances. Furthermore, after entering residential communities, drones face difficulties delivering supplies directly to customers' doorsteps due to the complex internal environment (e.g., obstructed by buildings and densely populated areas). Robotic dogs (or quadruped robots) possess excellent ground adaptability and flexibility, enabling them to navigate complex terrain (e.g., stairways and narrow passageways) and even access high-rise buildings via elevators. However, their relatively slow range and speed make them inadequate for long-distance delivery.

[0003] While both drones and robotic dogs currently have applications in logistics and distribution, there's no mature technical solution that effectively combines the two to achieve seamless integration, from long-distance rapid transportation to precise, intra-community delivery. In particular, the lack of an efficient and reliable base station design for material transfer between drones and robotic dogs results in low efficiency across the entire distribution system.

[0004] Therefore, the present invention aims to propose a terminal delivery system and handover base station that integrates drones and mechanical dogs. Through innovative base station design and intelligent handover process, efficient material handover between drones and mechanical dogs can be achieved, thereby solving the last-mile delivery problem and improving logistics delivery efficiency and user experience. Summary of the Invention

[0005] In light of this, the present invention provides a base station capable of docking drones and robotic dogs. This addresses the existing problem: while both drones and robotic dogs have certain applications in logistics and distribution, there is no mature technical solution that effectively combines the two to achieve seamless transitions from long-distance rapid transportation to precise delivery within residential communities. In particular, the lack of an efficient and reliable base station design for material transfer between drones and robotic dogs leads to low collaborative efficiency across the entire distribution system.

[0006] The technical solution adopted in the present invention is as follows:

[0007] A base station capable of docking a drone and a mechanical dog, comprising:

[0008] A docking chamber, wherein a feeding port is provided through the top of the docking chamber;

[0009] A drone, the drone is located at the top of the docking room, and a clamp for clamping cargo is provided at the bottom of the drone, and the clamp is located above the discharge port;

[0010] A mechanical dog is located in the docking room, a collection box is provided on the back of the mechanical dog, the collection box is located below the discharge port, a sealing door is slidably embedded in the top of the side wall of the collection box and is slidably connected to the door, a placement plate is slidably embedded in the interior of the collection box, and the placement plate is connected to the collection box via a first spring;

[0011] A transmission assembly is provided on the collection box, and the transmission assembly connects the sealing door and the placement plate. When the placement plate moves downward, the transmission assembly can drive the sealing door to close the collection box. When the placement plate moves upward, the transmission assembly can drive the sealing door to open the collection box.

[0012] In this technical solution, it should be noted that an inductive switch door can be set at the discharge port of the docking room, and a QR code for auxiliary positioning of the drone is provided on the inductive switch door. When the drone reaches the designated position on the top of the docking room, the inductive switches can be automatically opened, and the clamp of the drone adopts the existing technology to clamp or loosen the goods. The drone can reach the designated position on the top of the docking room through the existing positioning technology; the mechanical dog adopts the existing technology, and the collection box on the top of the mechanical dog is used to collect the goods dropped from the discharge port. When the goods fall onto the placement plate in the collection box, the sealed door can be automatically closed to ensure that the goods will not fall during transportation; in the specific implementation of this solution, taking the delivery of medicine from the hospital to the patient's home as an example, the drone Covering the distance from the airport to the community entrance (5-10km), the drone, carrying supplies, arrives above the docking room. It uses the QR code on the inductive door to assist in positioning until it securely docks at the designated location on the roof. The inductive door automatically opens, the drone's gripper releases, and the materials drop from the discharge port into the robotic dog's collection box inside the docking room. The weight of the cargo pushes the placement plate downward, which drives the sealing door through the transmission assembly to seal the collection box. This sealing mechanism not only prevents the goods from falling due to bumps or external factors during transportation, but also protects them from environmental influences, ensuring the integrity and safety of medicines or other supplies. The robotic dog then completes its journey through the community, climbing stairs or taking the elevator, and knocks on the door to deliver them to the door. To further enhance the system's intelligence and reliability, this invention incorporates the following technologies: High-precision drone positioning technology: The drone utilizes advanced satellite positioning systems (such as GPS and Beidou navigation systems) combined with visual recognition technology to ensure precise docking at the designated location on the roof of the docking room, even in complex environments. Furthermore, the drone's gripper incorporates intelligent sensors that monitor the cargo's status in real time, ensuring stable and secure gripping. Intelligent control of inductive door opening and closing: The inductive door opening and closing not only utilizes QR code-assisted positioning but also incorporates infrared or ultrasonic sensors to monitor the drone's docking status in real time. When the drone enters the designated location, the sensor automatically triggers the door opening and closing mechanism, enabling seamless docking and improving delivery efficiency. Autonomous navigation and obstacle avoidance technology for the robotic dog: The robotic dog is equipped with laser radar (LiDAR) and visual sensors, enabling it to autonomously plan its route within a residential complex and avoid obstacles and pedestrians in real time. Furthermore, the robotic dog features intelligent elevator interaction, connecting to the elevator control system via a wireless communication module, allowing it to autonomously ride the elevator, further enhancing delivery flexibility and efficiency. Cargo status monitoring and feedback system: During the cargo handover process, the placement plate inside the collection box is equipped with pressure sensors and weight sensors, which can monitor the weight and placement status of the cargo in real time.Once the goods successfully fall into the collection box, the sensor will feed back the information to the base station control system to ensure the reliability of the handover process. At the same time, the closing action of the sealed door will also be confirmed by the sensor to ensure the safety of the goods during transportation. The terminal interaction function of the mechanical dog: After the mechanical dog arrives at the patient's door, it can not only notify the patient by knocking on the door or making a prompt sound, but also display relevant information (such as order number, delivery items, etc.) through the display screen on its back, further enhancing the user experience. In addition, the mechanical dog can also be equipped with an intelligent voice interaction module to conduct simple voice communication with the patient to confirm the receipt status. Through this innovative base station design and intelligent handover process, the present invention realizes the efficient handover of materials between the drone and the mechanical dog, solves the problem of last-mile delivery, and improves the efficiency and reliability of logistics distribution.

[0013] Preferably, a mounting groove is provided on the side wall of the collection box, the mounting groove is vertically arranged, and a first rotating shaft is rotatably connected at the top of the mounting groove; the transmission assembly includes a gear, a rack and a drive assembly, the gear is fixedly sleeved on the first rotating shaft, the rack is arranged at the bottom of the sealing door, the gear and the rack are engaged with each other, and the drive assembly connects the transmission shaft and the placement plate, and when the placement plate moves up or down, the first rotating shaft can be driven to rotate forward or reverse through the drive assembly.

[0014] In this technical solution, it should be noted that when goods fall from the discharge port into the collection box and contact the placement plate, the placement plate moves downward due to the weight of the goods. At this point, the downward movement of the placement plate is transmitted to the first rotating shaft via the drive assembly. The drive assembly is used to convert the vertical movement of the placement plate into rotational movement of the first rotating shaft. As the placement plate moves downward, the drive assembly drives the first rotating shaft to rotate clockwise. This clockwise rotation of the first rotating shaft further rotates the gear on it. Because the gear and rack mesh together, the rotation of the gear drives the rack to move horizontally. The rack's movement is perpendicular to the gear's rotation, which in turn drives the sealing door to close the collection box. Once the robotic dog carries the collection box to the delivery location, the recipient (such as the consignee or a courier pick-up point staff member) needs to open the sealing door to remove the goods. During the process of opening the sealing door, the rack moves horizontally as the sealing door moves. Because the rack and gear mesh together, the rack's movement drives the gear to rotate counterclockwise (assuming it rotates clockwise when closed). The rotation of the gear is transmitted to the first rotating shaft via the drive assembly, in turn driving the attached placement plate upward. This upward movement of the placement plate is of significant design significance. As the placement plate rises, the goods are lifted to a higher position, significantly reducing the need for the recipient to bend or squat, making the collection of goods more convenient and labor-saving. This design not only improves operator comfort but also reduces the physical fatigue and risk of injury caused by frequent bending or squatting. It is particularly suitable for scenarios where frequent collection of goods occurs, such as express delivery stations or medical supply distribution points. The drive assembly converts the vertical movement of the placement plate into rotational motion of the first rotating shaft, which is then driven to close the sealing door through the meshing of the gear and rack. This entire process requires no human intervention, achieving automated cargo collection and sealing operations, significantly improving the efficiency and reliability of logistics distribution. Furthermore, the present invention incorporates a sealing strip along the edge of the sealing door to enhance the sealing of the collection box. The sealing strip can be made of a flexible material (such as rubber or silicone) and can fit tightly against the edge of the collection box opening when the sealing door is closed, preventing dust, rainwater, and other contaminants from entering the collection box, thereby protecting the integrity of the goods.

[0015] Preferably, the driving assembly includes a second rotating shaft, a conveyor belt and a connecting plate. The second rotating shaft is rotatably connected in the mounting groove, and the second rotating shaft is located below the first rotating shaft. The two ends of the conveyor belt are sleeved on two transmission shafts. One end of the connecting plate is connected to the conveyor belt, and the other end is connected to the placement plate.

[0016] In this technical solution, it should be noted that the drive assembly specifically comprises a second rotating shaft, a conveyor belt, and a connecting plate. When goods fall from the discharge port into the collection bin and contact the placement plate, the placement plate is moved downward by the weight of the goods. This downward movement of the placement plate is transmitted to the conveyor belt via the connecting plate. Because the connecting plate is fixedly connected to the conveyor belt, the vertical downward movement of the placement plate causes the conveyor belt to move accordingly on the second rotating shaft. This movement of the conveyor belt further drives the first rotating shaft to rotate clockwise. This clockwise rotation of the first rotating shaft is achieved through the tension and friction of the conveyor belt. As the conveyor belt moves on the second rotating shaft, the friction between the conveyor belt and the first rotating shaft causes the first rotating shaft to rotate. As the first rotating shaft rotates clockwise, the gear on it also rotates. Because the gear meshes with the rack, the rotation of the gear drives the rack to move horizontally. The rack's movement is perpendicular to the rotation of the gear, which in turn drives the sealing door to move horizontally, ultimately closing the collection bin. This unique drive assembly design achieves efficient conversion between the vertical motion of the placement plate and the rotational motion of the first rotating shaft. The meshing of the gear and rack converts the rotational motion into horizontal movement of the sealing door. The introduction of the conveyor belt and connecting plate not only simplifies the transmission structure but also improves the reliability and stability of the system.

[0017] Preferably, the gear is a half gear. When the sealing door is fully opened, the tooth block of the half gear does not contact the rack at the bottom of the sealing door. In the process of the goods falling into the collection box and driving the placement plate to move downward, when the top of the goods is completely lower than the bottom of the sealing door, the tooth block of the half gear contacts the rack and drives the sealing door to close.

[0018] It's important to note that in this technical solution, to prevent damage to the cargo during transfer from the drone to the collection bin, the initial distance between the placement plate and the cargo on the drone's gripper is strictly controlled to prevent damage caused by a large drop. However, due to the height of the cargo, when it lands on the placement plate, the plate moves downward due to gravity, which in turn drives the sealing door to gradually close via the drive assembly. In this case, if the sealing door closes prematurely, it could come into contact with the cargo before it has fully descended below the sealing door, causing motion interference and even damage. To address this potential issue, this solution cleverly incorporates a half-gear design. A half-gear is a special gear with gears on only one portion of its circumference, while the other portion is gearless. This design ensures that during rotation, the half-gear only drives the rack when the gears contact the rack. The specific operating process is as follows: Initially, the sealing door is fully open, and the half-gear is in a specific initial position, with the gearless portion facing the rack. Even if the half-gear rotates due to slight vibration or displacement of the placement plate, the rack remains stationary because the toothless portion of the gear does not mesh with the rack. When the drone releases the cargo onto the placement plate, the plate begins to move downward due to the weight of the cargo. This downward movement of the placement plate is transmitted to the half-gear via a drive assembly (such as a conveyor belt, connecting rod, or other transmission mechanism), causing it to rotate. As the half-gear rotates, its toothed portion gradually approaches the rack. When the top of the cargo is completely below the bottom of the sealing door, the toothed portion of the half-gear rotates to a position that contacts the rack. At this point, the toothed portion of the half-gear engages with the rack, driving the rack horizontally. This meshing of the half-gear and rack drives the sealing door horizontally, gradually closing the collection box. The closing action of the sealing door is initiated only after the cargo is fully seated, thus avoiding motion interference. The edge of the sealing door securely fits the opening of the collection box via a flexible sealing strip, ensuring a good seal. When the robotic dog arrives at the delivery location, the recipient opens the sealed door to retrieve the goods. During the process of opening the sealed door, the rack moves in the opposite direction as the sealed door moves, thereby driving the half-gear to rotate in the opposite direction. Eventually, the half-gear returns to its initial position, with the toothless portion facing the rack again, ready for the next shipment. By adopting a half-gear structure, this solution not only effectively avoids motion interference between the goods and the sealed door, but also ensures the smoothness and reliability of the entire closing and opening process. This innovative design not only protects the integrity of the goods, but also improves the operating efficiency and safety of the entire system, providing an efficient and reliable solution for the logistics distribution system that integrates drones and robotic dogs.

[0019] Preferably, a battery compartment is provided on the fuselage of the drone, and a battery replacement device is provided on the top of the docking room;

[0020] The battery replacement device includes a storage box, which is located on one side of the drone. A pallet is slidably embedded in the storage box. The bottom of the pallet is connected to the storage box through a second spring. Several batteries are stacked on the pallet. A first opening and a second opening are respectively provided on both sides of the storage box for a single battery to pass through. The first opening and the second opening are aligned with the battery compartment, and the first opening is close to the battery compartment. An electric push rod is provided on the side of the storage box away from the drone. A push plate is provided at the output end of the electric push rod, and the push plate faces the second opening.

[0021] It should be noted that in this technical solution, a further optimized design of the present invention addresses the issue of low battery power that can occur during docking. A highly efficient automatic battery replacement device has been designed for drones. This device, integrated into the top of the docking compartment, seamlessly integrates with the drone's battery compartment, enabling rapid battery replacement and significantly improving the drone's operational efficiency and endurance. Specifically, the battery replacement device in the docking compartment includes a storage box located on one side of the drone. A tray is embedded within the box via slide rails. The bottom of the tray is connected to the storage box via a second spring, enabling vertical movement. Several spare batteries are stacked on the tray, arranged in sequence to ensure sufficient power for each replacement. The storage box is provided with a first opening and a second opening on either side. These openings are sized to match the dimensions of individual batteries and are aligned with the entrance and exit of the drone's battery compartment. The first opening, located near the drone's battery compartment, is used to push spare batteries into the compartment; the second opening is for the push plate of an electric actuator to enter and move the spare batteries. On the side of the storage box facing away from the drone, an electric actuator is located, with the push plate connected to its output end, facing the second opening. When the drone reaches the designated position on the top of the docking room, if it detects that the battery power is too low, the battery replacement device will start. The push plate of the electric push rod enters the storage box from the second opening, pushes the spare battery stacked on the top of the pallet out of the first opening, and accurately enters the battery compartment of the drone. At the same time, the old battery in the drone's battery compartment is pushed out from the other side by the new battery and falls into the designated recycling position on the top of the docking room instead of entering the storage box. After the battery replacement is completed, the electric push rod resets, and the pallet moves upward under the elastic force of the second spring, pushing the next spare battery to the top of the storage box. At this time, the spare battery is ready, waiting for the next battery replacement operation. This automated battery replacement mechanism not only improves the endurance of the drone, but also reduces manual intervention and improves the intelligence level of the entire system.

[0022] Preferably, a box is provided on one side of the drone, and the box is located below the battery compartment. A sealing plate is slidably embedded in the box. The bottom of the sealing plate is connected to the box via a third spring. The top of the sealing plate extends upward outside the box and seals one side of the battery compartment. The sealing plate has a first slope on one end facing the storage box, and the first slope is inclined from top to bottom in a direction close to the storage box. A baffle is hinged to the side of the drone away from the storage box via a hinge shaft. A coil spring is connected between the baffle and the hinge shaft. The baffle seals the battery compartment.

[0023] It should be noted that in this technical solution, a further optimized design of the present invention incorporates a sealing plate and baffle structure to ensure a good seal between the drone's battery compartment and when it's not being replaced, while also enabling quick battery replacement. This design not only effectively protects the batteries within the compartment from environmental influences but also enables automated opening and closing during battery replacement, improving system reliability and operational convenience. Specifically, a housing is provided on one side of the drone, located below the battery compartment. A sealing plate is slidably embedded within the housing, with its bottom connected to the housing via a third spring. The top of the sealing plate extends upward beyond the housing, sealing one side of the battery compartment and creating a sealed environment. The end of the sealing plate facing the storage box is provided with a first inclined surface, which slopes downward from top to bottom, toward the storage box. This inclined surface design is one of the key innovations of this solution. Furthermore, a baffle is hinged to the side of the drone facing away from the storage box via a hinged shaft, with a coil spring connected between the baffle and the hinged shaft. The coil spring automatically resets the baffle, sealing the other side of the battery compartment. This design ensures the battery compartment remains sealed when not being replaced, preventing dust, moisture, and other contaminants from entering the compartment. During battery replacement, when the electric actuator pushes the new battery through the first opening of the storage box and into the battery compartment, it first contacts the first inclined surface of the sealing plate. The special design of the first inclined surface breaks down the horizontal thrust of the new battery into a vertical downward pressure. This pressure acts on the sealing plate, causing it to automatically move downward under the influence of the third spring. The downward movement of the sealing plate not only makes room for the new battery to enter, but also prevents the sealing plate from obstructing the new battery's advancement. Simultaneously, the old battery in the compartment, pushed by the new battery, is pushed out from the other side of the compartment. During this process, the old battery contacts the barrier, which, connected to the hinged shaft via a coil spring, automatically opens when subjected to external force. This design ensures that the old battery can be smoothly ejected without obstruction by the barrier. When the external force disappears, the coil spring automatically returns the barrier to its original position, resealing the battery compartment. This sealing plate and barrier design not only seals the battery compartment but also, through a clever mechanical structure, enables automated opening and closing during battery replacement. The design of the first bevel allows the sealing plate to automatically move out of the way when a new battery is inserted, while the combination of a coil spring and an articulated shaft ensures that the baffle automatically opens and resets when the old battery is removed. This design not only improves the efficiency of battery replacement but also reduces the possibility of mechanical failure, providing reliable protection for the efficient operation of the drone. Through this innovative sealing and automatic opening mechanism, this solution ensures the sealing of the battery compartment while enabling rapid battery replacement, significantly improving the drone's efficiency and endurance. This design is particularly suitable for drone applications where frequent battery replacement is required, providing important technical support for the drone's automated operation.

[0024] Preferably, a first guide rail is further provided on the top of the docking room, the first guide rail is parallel to the drone, a first electric slide is provided on the first guide rail and is slidably matched with the drone, a second guide rail is fixedly connected to the top of the first electric slide, the second guide rail is perpendicular to the first guide rail, a second electric slide is slidably connected to the second guide rail and is slidably matched with the drone, and the storage box is provided on the second electric slide.

[0025] It should be noted that in this technical solution, a movable storage box structure was specifically designed to address the potential interference of the storage box with the drone during landing and to ensure precise alignment of the storage box with the battery compartment during battery replacement. This structure, through a combination of a motorized slide and guide rails, enables flexible movement of the storage box, significantly improving system reliability and ease of operation. Specifically, a first guide rail is provided at the top of the docking chamber, parallel to the drone's parking orientation. A first motorized slide is mounted on the first guide rail, slidably engaged with it. A second guide rail is fixedly connected to the top of the first motorized slide, perpendicular to the first rail. A second motorized slide is slidably connected to the second guide rail, on which the storage box is mounted. This design allows the storage box to move in two directions: along the first guide rail, the first motorized slide moves on the first guide rail, driving the entire storage box parallel to the drone. Along the second guide rail, the second motorized slide moves on the second guide rail, enabling fine-tuning of the storage box perpendicular to the drone. This dual-guide rail and dual motorized slide design allows precise control of the storage box's position. During battery replacement, the position of the first and second motorized slides can be adjusted to ensure precise alignment of the second opening of the storage box with the inlet of the drone's battery compartment. This alignment mechanism not only improves battery replacement reliability but also reduces mechanical failures caused by misalignment. Furthermore, during drone landing, the storage box can be moved to a farther position via the first motorized slide to avoid interference with the drone's landing. This design ensures that the drone will not be obstructed by the storage box during landing, improving the overall safety of the system. The dual guide rails and dual motorized slides allow the storage box's position to be precisely adjusted, ensuring precise alignment of the second opening with the inlet of the drone's battery compartment. This design significantly improves the reliability and efficiency of battery replacement. During drone landing, the storage box can be moved to a farther position to avoid interference with the drone's landing. This design enhances the overall safety of the system and ensures smooth operation of the drone during landing. The use of motorized slides makes storage box movement fully automated, reducing manual intervention. This design not only improves operational convenience but also enhances overall system efficiency. By adjusting the position of the motorized slides, the storage box can adapt to different drone models and battery compartment designs, increasing the system's versatility and adaptability. This innovative storage box movement mechanism not only solves the interference problem during drone landing but also improves the reliability of battery replacement through precise alignment. This design provides important technical support for automated battery replacement in drones, significantly improving the efficiency and endurance of drones. Furthermore, to improve the accuracy of the alignment of the second opening with the drone's battery compartment, a comprehensive solution combining sensor technology and mechanical guidance can be used.The specific implementation method is as follows: High-precision positioning sensors are installed on the storage box and the drone's battery compartment to monitor their relative position in real time. These sensors can be photoelectric sensors, laser sensors, or visual sensors (such as cameras). Using the position information obtained by the sensors, the controller can precisely adjust the positions of the first and second motorized slides to ensure alignment of the second opening with the battery compartment.

[0026] Preferably, a recycling box is further provided on the top of the docking room, and the recycling box is located on a side of the drone away from the storage box. The recycling box can be driven by a moving component to move on the top of the docking room.

[0027] It's important to note that in this technical solution, a recycling bin is installed on the roof of the docking compartment to improve the stability and safety of the drone battery replacement process and enable efficient recycling of used batteries. This bin is located on the side of the drone away from the storage bin and is driven by a mobile assembly, allowing it to move across the roof of the docking compartment. This design not only provides a dedicated recycling area for used batteries but also plays an important supporting role in the battery replacement process. The recycling bin moves in the same manner as the storage bin, using rails. When the drone battery is replaced, the old battery is ejected from the battery compartment and falls directly into the recycling bin. The recycling bin ensures centralized management and recycling of used batteries, preventing them from being scattered across the roof of the docking compartment, improving operational safety and convenience. This centralized collection method facilitates subsequent centralized charging, testing, or disposal of used batteries, further optimizing the battery management process. During the battery replacement process, the recycling bin can be moved to the other side of the drone, providing support against the other side. Because the drone may experience slight displacement during battery replacement due to external forces (such as the propulsion of the new battery), the recovery bin's support function effectively prevents the drone from moving, ensuring stability during the battery replacement process. This design physically limits the drone's shaking and improves the reliability of battery replacement, which is particularly important in unmanned automated scenarios.

[0028] Preferably, an electric opening and closing door is provided on one side of the parking room.

[0029] In this technical solution, it should be noted that when the mechanical dog goes out, the electric switch door will open automatically.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0031] 1. Efficiently linking drones and robotic dogs solves the last-mile delivery challenge. This combination of drones and robotic dogs seamlessly transitions from long-distance transport to precise delivery within residential communities. Drones cover the 5-10 km distance from the airport to the residential entrance, while robotic dogs handle shorter distances within the community, including climbing stairs or taking elevators. This collaborative approach significantly improves the efficiency and flexibility of logistics and delivery, making it particularly suitable for applications such as medical supplies, where timeliness and safety are paramount.

[0032] 2. The semi-gear structure and transmission assembly design enable smooth transfer of cargo from the drone to the robotic dog. The special design of the semi-gear prevents motion interference between the cargo and the sealed door, ensuring the integrity and safety of the cargo during transportation. Furthermore, the sealed door's automatic closing mechanism effectively prevents cargo from falling due to bumps or external factors during transportation.

[0033] 3. The use of rail-mounted mobile storage and recovery bins, combined with precise motorized slide control, significantly improves the efficiency and reliability of the battery replacement process. The positions of the storage and recovery bins can be flexibly adjusted based on the specific location of the drone, ensuring precise alignment during battery replacement and reducing mechanical failures caused by misalignment, thus enabling fast and stable battery replacement.

[0034] 4. The recycling bin supports the other side of the drone during battery replacement, preventing the drone from slight movement due to external forces (such as the propulsion of the new battery). This design physically limits the drone's movement and improves the reliability of battery replacement, which is particularly important in unmanned automated scenarios.

[0035] 5. A unique drive assembly design (including a second shaft, conveyor belt, and connecting plate) achieves efficient conversion between the vertical motion of the placement plate and the rotational motion of the first shaft. The introduction of the conveyor belt and connecting plate not only simplifies the transmission structure but also improves system reliability and stability. This design reduces the number of mechanical components, reduces the failure rate, and improves overall system efficiency.

[0036] 6. Through the design of the transmission component, when the sealed door is opened, the placement plate automatically rises, lifting the goods to a higher position, significantly reducing the need for the recipient to bend or squat, making the collection of goods more convenient and labor-saving. This design not only improves the operator's operating comfort, but also reduces the physical fatigue and injury risk caused by frequent bending or squatting. It is particularly suitable for scenarios where goods are frequently collected, such as express delivery stations or medical supply distribution points. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Example 1

[0054] like Figures 1-8 As shown, the embodiment of the present invention discloses a base station capable of docking a drone 3 and a mechanical dog 5, comprising:

[0055] A docking chamber 1, wherein a feeding port 4 is provided on the top of the docking chamber 1;

[0056] The drone 3 is located at the top of the docking chamber 1. The bottom of the drone 3 is provided with a clamp 16 for clamping the cargo, and the clamp 16 is located above the discharge port 4;

[0057] A mechanical dog 5 is located in the docking chamber 1. A collection box 6 is provided on the back of the mechanical dog 5. The collection box 6 is located below the discharge port 4. A sealing door 14 is slidably embedded at the top of the side wall of the collection box 6 and is slidably connected to the sealing door 14. A placement plate 7 is slidably embedded inside the collection box 6. The placement plate 7 is connected to the collection box 6 via a first spring 9.

[0058] The transmission assembly is arranged on the collection box 6, and the transmission assembly transmits and connects the sealing door 14 and the placement plate 7. When the placement plate 7 moves downward, the transmission assembly can drive the sealing door 14 to close the collection box 6. When the placement plate 7 moves upward, the transmission assembly can drive the sealing door 14 to open the collection box 6.

[0059] It should be noted that an inductive switch door can be set at the discharge port 4 of the docking room 1, and a QR code for assisting the positioning of the drone 3 is provided on the inductive switch door. When the drone 3 reaches the designated position on the top of the docking room 1, the inductive switches can be automatically opened, and the clamp 16 of the drone 3 adopts the existing technology, which can clamp or loosen the goods. The drone 3 can reach the designated position on the top of the docking room 1 through the existing positioning technology; the mechanical dog 5 adopts the existing technology, and the collection box 6 on the top of the mechanical dog 5 is used to collect the goods falling from the discharge port 4. When the goods fall onto the placement plate 7 in the collection box 6, the sealing door 14 can be automatically closed to ensure that the goods will not fall during transportation; in the specific implementation of this plan, taking the delivery of medicine from the hospital to the patient's home as an example, the drone 3 covers the machine The distance from the field to the community entrance is 5-10 km. After drone 3, carrying supplies, arrives above docking room 1, it uses the QR code on the inductive door to assist in positioning until drone 3 securely docks at the designated location on the top of docking room 1. At this point, the inductive door automatically opens, and drone 3's gripper 16 releases, allowing the materials to fall from the discharge port 4 into collection box 6 of robotic dog 5 inside docking room 1. The weight of the cargo causes plate 7 inside collection box 6 to move downward, which, through the transmission assembly, drives sealing door 14 to seal collection box 6. This sealing mechanism not only prevents the goods from falling due to bumps or external factors during transportation, but also protects the goods from environmental influences, ensuring the integrity and safety of the medicines or other supplies. Robot dog 5 then completes its journey through the community, climbing stairs or taking the elevator, and knocks on the door to deliver them to the door. To further enhance the system's intelligence and reliability, the present invention incorporates the following technologies: High-precision positioning technology for drone 3: Drone 3 utilizes advanced satellite positioning systems (such as GPS and Beidou navigation systems) combined with visual recognition technology to ensure precise docking at the designated location on top of docking room 1, even in complex environments. Furthermore, drone 3's gripper 16 utilizes intelligent sensors to monitor the cargo's status in real time, ensuring stable and secure gripping. Intelligent control of inductive door opening and closing: Inductive door opening and closing not only utilizes QR code-assisted positioning but also incorporates infrared or ultrasonic sensors to monitor drone 3's docking status in real time. When drone 3 enters the designated location, the sensors automatically trigger the door opening and closing mechanism, enabling seamless docking and improving delivery efficiency. Autonomous navigation and obstacle avoidance technology for robot dog 5: Equipped with laser radar (LiDAR) and visual sensors, robot dog 5 can autonomously plan its path within the residential complex, avoiding obstacles and pedestrians in real time. Furthermore, robot dog 5 features intelligent elevator interaction, connecting to elevator control systems via a wireless communication module, enabling autonomous elevator rides, further enhancing delivery flexibility and efficiency.Cargo Status Monitoring and Feedback System: During the cargo handover process, the placement plate 7 inside the collection box 6 is equipped with pressure sensors and weight sensors to monitor the cargo's weight and placement status in real time. Once the cargo successfully lands in the collection box 6, the sensors transmit this information to the base station control system, ensuring the reliability of the handover process. Furthermore, the closing of the sealing door 14 is confirmed by sensors, ensuring the safety of the cargo during transportation. The end-user interaction function of the robotic dog 5: Upon arriving at the patient's doorstep, the robotic dog 5 not only notifies the patient by knocking or emitting an audible notification, but also displays relevant information (such as order number and delivery items) on its back display, further enhancing the user experience. Furthermore, the robotic dog 5 can be equipped with an intelligent voice interaction module, enabling simple voice communication with the patient to confirm the delivery status. Through this innovative base station design and intelligent handover process, the present invention achieves efficient cargo handover between the drone 3 and the robotic dog 5, solving the last-mile delivery challenge and improving the efficiency and reliability of logistics distribution.

[0060] like Figure 4As shown, in this embodiment, the sidewall of the collection box 6 is provided with a vertical mounting slot, with a first rotating shaft 10 rotatably connected to its top. The transmission assembly includes a gear 13, a rack 15, and a drive assembly. The gear 13 is fixedly mounted on the first rotating shaft 10, and the rack 15 is located at the bottom of the sealing door 14. The gear 13 and rack 15 mesh with each other. The drive assembly connects the transmission shaft to the placement plate 7. When the placement plate 7 moves upward or downward, the drive assembly drives the first rotating shaft 10 to rotate forward or reverse. It should be noted that when cargo falls from the discharge port 4 into the collection box 6 and contacts the placement plate 7, the placement plate 7 moves downward due to the weight of the cargo. At this time, the downward movement of the placement plate 7 is transmitted to the first rotating shaft 10 via the drive assembly. The drive assembly is used to convert the vertical movement of the placement plate 7 into rotational motion of the first rotating shaft 10. As the placement plate 7 moves downward, the drive assembly drives the first rotating shaft 10 to rotate clockwise. The clockwise rotation of the first rotating shaft 10 further rotates the gear 13 on it. Because the gear 13 meshes with the rack 15, the rotation of the gear 13 drives the rack 15 to move horizontally. The movement of the rack 15 is perpendicular to the rotation of the gear 13, which in turn drives the sealed door 14 to close the collection box 6. When the robotic dog 5 arrives at the delivery location carrying the collection box 6, the recipient (such as the consignee or a courier service representative) needs to open the sealed door 14 to remove the goods. During the opening of the sealed door 14, the rack 15 moves horizontally as the door 14 moves. Because the rack 15 meshes with the gear 13, its movement drives the gear 13 to rotate counterclockwise (assuming it rotates clockwise when closed). The rotation of the gear 13 is transmitted to the first rotating shaft 10 via the drive assembly, which in turn drives the attached placement plate 7 upward. This upward movement of the placement plate 7 is of great design significance. As the placement plate 7 rises, the goods are lifted to a higher position, which significantly reduces the degree to which the recipient has to bend or squat, making the picking up of the goods more convenient and labor-saving. This design not only improves the operating comfort of the recipient, but also reduces the risk of physical fatigue and injury caused by frequent bending or squatting. It is particularly suitable for scenarios where goods are frequently collected, such as express stations or medical supplies distribution points. The vertical movement of the placement plate 7 is converted into the rotational movement of the first rotating shaft 10 by the drive component, and the sealing door 14 is further driven to close through the engagement of the gear 13 and the rack 15. The entire process does not require human intervention, realizing the automated operation of cargo reception and sealing, and greatly improving the efficiency and reliability of logistics distribution. Furthermore, the present invention also provides a sealing strip on the edge of the sealing door 14 to enhance the sealing of the collection box 6.The sealing strip can be made of a flexible material (such as rubber or silicone) and can fit tightly with the opening edge of the collection box 6 when the sealing door 14 is closed, preventing external dust, rainwater or other pollutants from entering the collection box 6, thereby protecting the integrity of the goods.

[0061] like Figure 4 As shown, in this embodiment, the drive assembly includes a second rotating shaft 11, a conveyor belt 12, and a connecting plate 8. The second rotating shaft 11 is rotatably connected within the mounting slot and is located below the first rotating shaft 10. The conveyor belt 12 is sleeved onto two drive shafts at both ends. One end of the connecting plate 8 is connected to the conveyor belt 12, and the other end is connected to the placement plate 7. It should be noted that the drive assembly specifically includes the second rotating shaft 11, the conveyor belt 12, and the connecting plate 8. When cargo falls from the discharge port 4 into the collection box 6 and contacts the placement plate 7, the placement plate 7 moves downward due to the weight of the cargo. This downward movement of the placement plate 7 is transmitted to the conveyor belt 12 via the connecting plate 8. Because the connecting plate 8 is fixedly connected to the conveyor belt 12, the vertical downward movement of the placement plate 7 causes the conveyor belt 12 to move accordingly on the second rotating shaft 11. The movement of the conveyor belt 12 further drives the first rotating shaft 10 to rotate clockwise. The clockwise rotation of the first rotating shaft 10 is achieved through the tension and friction of the conveyor belt 12. When the conveyor belt 12 moves on the second rotating shaft 11, the first rotating shaft 10 will be driven to rotate due to the friction between the conveyor belt 12 and the first rotating shaft 10. As the first rotating shaft 10 rotates clockwise, the gear 13 on it also rotates. Since the gear 13 and the rack 15 are engaged with each other, the rotation of the gear 13 will drive the rack 15 to move in the horizontal direction. The moving direction of the rack 15 is perpendicular to the rotation direction of the gear 13, thereby driving the sealing door 14 to move horizontally, and finally closing the collection box 6. Through this unique drive component design, the present invention realizes the efficient conversion between the vertical movement of the placement plate 7 and the rotational movement of the first rotating shaft 10, and converts the rotational movement into the horizontal movement of the sealing door 14 through the engagement of the gear 13 and the rack 15. The introduction of the conveyor belt 12 and the connecting plate 8 not only simplifies the transmission structure, but also improves the reliability and stability of the system.

[0062] like Figure 4As shown, in this embodiment, the gear 13 is a half gear 13. When the sealing door 14 is fully open, the gear block of the half gear 13 does not contact the rack 15 at the bottom of the sealing door 14. As the cargo falls into the collection bin 6 and drives the placement plate 7 downward, once the top of the cargo is completely below the bottom of the sealing door 14, the gear block of the half gear 13 contacts the rack 15, driving the sealing door 14 to close. It should be noted that to ensure that the cargo is not damaged during transfer from the drone 3 to the collection bin 6, the initial distance between the placement plate 7 and the cargo on the drone 3 fixture 16 is strictly controlled to prevent damage to the cargo due to a large drop. However, due to the inherent height of the cargo, when the cargo falls onto the placement plate 7, the placement plate 7 moves downward due to gravity, which in turn drives the sealing door 14 to gradually close via the drive assembly. In this case, if the closing action of the sealing door 14 is initiated prematurely, it may come into contact with the cargo before it has fully descended below the sealing door 14, causing motion interference and even damage to the cargo. To address this potential problem, this solution cleverly designs gear 13 as a half-gear 13. Half-gear 13 is a special gear 13, with only one portion of its circumference having teeth, while the other portion lacks teeth. This design ensures that during rotation, half-gear 13 only drives rack 15 when the teeth contact the rack 15. The specific operation is as follows: In the initial state, the sealing door 14 is fully open, and half-gear 13 is in a specific initial position, with its toothless portion facing rack 15. At this point, even if half-gear 13 rotates due to slight vibration or slight displacement of the placement plate 7, the rack 15 will not be moved due to the lack of meshing between the toothless portion and the rack 15, and the sealing door 14 will remain stationary. When drone 3 releases cargo onto placement plate 7, the placement plate 7 begins to move downward due to the weight of the cargo. This downward movement of the placement plate 7 is transmitted to half-gear 13 via a drive assembly (such as conveyor belt 12, connecting rod, or other transmission mechanism), causing it to rotate. As the half gear 13 rotates, its tooth block part gradually approaches the rack 15. When the top of the goods is completely lower than the bottom of the sealing door 14, the tooth block part of the half gear 13 just rotates to the position of contact with the rack 15. At this time, the tooth block of the half gear 13 begins to mesh with the rack 15, driving the rack 15 to move horizontally. Under the meshing action of the half gear 13 and the rack 15, the rack 15 drives the sealing door 14 to move horizontally, gradually closing the collection box 6. The closing action of the sealing door 14 is not started until the goods are fully in place, thus avoiding the problem of motion interference. The edge of the sealing door 14 is tightly fitted with the opening of the collection box 6 through a flexible sealing strip, ensuring good sealing performance. When the mechanical dog 5 arrives at the delivery location, the person picking up the goods opens the sealing door 14 to take out the goods.During the process of opening the sealing door 14, the rack 15 will move in the opposite direction as the sealing door 14 moves, thereby driving the half-gear 13 to rotate in the opposite direction. Finally, the half-gear 13 returns to its initial position, and the toothless portion faces the rack 15 again, ready for the next cargo reception. By adopting the half-gear 13 structure, this solution not only effectively avoids motion interference between the cargo and the sealing door 14, but also ensures the smoothness and reliability of the entire closing and opening process. This innovative design not only protects the integrity of the cargo, but also improves the operating efficiency and safety of the entire system, providing an efficient and reliable solution for the logistics distribution system in which the drone 3 and the mechanical dog 5 are linked.

[0063] Example 2

[0064] like Figure 5-Figure 8As shown, this embodiment is roughly the same as the above embodiment, except that a battery compartment 19 is provided on the fuselage 18 of the drone 3, and a battery 29 replacement device is provided on the top of the docking room 1; the battery 29 replacement device includes a storage box 17, which is located on one side of the drone 3, and a support plate 33 is slidably embedded in the storage box 17. The bottom of the support plate 33 is connected to the storage box 17 by a second spring 23, and a number of batteries 29 are stacked on the support plate 33. The two sides of the storage box 17 are respectively provided with a first opening 31 and a second opening 32 for a single battery 29 to pass through, the first opening 31 and the second opening 32 are aligned with the battery compartment 19, and the first opening 31 is close to the battery compartment 19, and the side of the storage box 17 away from the drone 3 is provided with an electric push rod 24, and the output end of the electric push rod 24 is provided with a push plate 30, and the push plate 30 faces the second opening 32. It should be noted that in a further optimized design of the present invention, a highly efficient automatic replacement device for the drone's 3 batteries 29 has been designed to address the potential problem of insufficient battery 29 during docking. This device, integrated into the top of the docking chamber 1, seamlessly integrates with the drone's 3 battery compartment 19, enabling rapid battery replacement and significantly improving the drone's 3's operational efficiency and endurance. Specifically, the battery replacement device on the top of the docking chamber 1 includes a storage box 17 located on one side of the drone 3. A support plate 33 is embedded within the box via slide rails. The bottom of the support plate 33 is connected to the storage box 17 via a second spring 23, enabling vertical movement. Several spare batteries 29 are stacked on the support plate 33, arranged in sequence to ensure sufficient power for each replacement. A first opening 31 and a second opening 32 are respectively formed on either side of the storage box 17. The dimensions of these openings match those of a single battery 29 and align with the entrance and exit of the drone's 3 battery compartment 19. The first opening 31, located near the drone 3's battery compartment 19, is used to push the spare battery 29 into the compartment. The second opening 32 allows the push plate 30 of the electric actuator 24 to enter and move the spare battery 29. On the side of the storage box 17 facing away from the drone 3, an electric actuator 24 is installed. Its output end is connected to the push plate 30, which faces the second opening 32. When the drone 3 reaches a designated location at the top of the docking chamber 1, if the battery 29 is detected to be low on charge, the battery 29 replacement mechanism is activated. The push plate 30 of the electric actuator 24 enters the storage box 17 through the second opening 32, pushing the spare battery 29, stacked on the topmost portion of the tray 33, out of the first opening 31 and into the drone 3's battery compartment 19. Simultaneously, the old battery 29 in the drone 3's battery compartment 19 is pushed out from the other side by the new battery 29, landing in the designated recovery location at the top of the docking chamber 1, rather than entering the storage box 17.After battery 29 is replaced, electric push rod 24 returns to its original position, and support plate 33 moves upward under the elastic force of second spring 23, pushing the next spare battery 29 to the top of storage box 17. At this point, spare battery 29 is ready for the next battery 29 replacement operation. This automated battery 29 replacement mechanism not only improves the endurance of drone 3 but also reduces manual intervention, enhancing the intelligence level of the entire system.

[0065] like Figure 6As shown, in this embodiment, a box 22 is provided on one side of the fuselage 18. The box 22 is located below the battery compartment 19. A sealing plate 20 is slidably embedded in the box 22. The bottom of the sealing plate 20 is connected to the box 22 by a third spring 34. The top of the sealing plate 20 extends upwardly out of the box 22 and seals one side of the battery compartment 19. The end of the sealing plate 20 facing the storage box 17 is provided with a first inclined surface 21, which is inclined from top to bottom in a direction approaching the storage box 17. A baffle 35 is hinged to the side of the drone 3 away from the storage box 17 via a hinge shaft. A coil spring is connected to the baffle 35 and seals the battery compartment 19. It should be noted that in a further optimized design of the present invention, the structures of the sealing plate 20 and the baffle 35 are specially designed to ensure that the battery compartment 19 of the drone 3 maintains good sealing when not being replaced and to enable rapid replacement of the battery 29. This design not only effectively protects the batteries 29 in the battery compartment 19 from environmental influences but also enables automated opening and closing during battery 29 replacement, improving system reliability and operational convenience. Specifically, a housing 22 is provided on one side of the drone 3, located below the battery compartment 19. A sealing plate 20 is slidably embedded within the housing 22, with the bottom of the sealing plate 20 connected to the housing 22 via a third spring 34. The top of the sealing plate 20 extends upward beyond the housing 22, sealing one side of the battery compartment 19 and creating a sealed environment. The end of the sealing plate 20 facing the storage box 17 is provided with a first inclined surface 21, which slopes downward toward the storage box 17. This inclined surface design is one of the key innovations of this solution. Furthermore, a baffle 35 is hingedly connected to the side of the drone 3 facing away from the storage box 17 via a hinge shaft. A coil spring is connected between the baffle 35 and the hinge shaft. The coil spring automatically resets the baffle 35, sealing the other side of the battery compartment 19. This design ensures that the battery compartment 19 remains sealed when not being replaced, preventing dust, moisture, or other contaminants from entering the compartment 19. During battery 29 replacement, when the electric actuator 24 pushes a new battery 29 through the first opening 31 of the storage box 17 and into the battery compartment 19, the new battery 29 first contacts the first inclined surface 21 of the sealing plate 20. Due to the special design of the first inclined surface 21, the horizontal thrust of the new battery 29 is converted into a vertical downward pressure. This pressure acts on the sealing plate 20, causing it to automatically move downward under the influence of the third spring 34. The downward movement of the sealing plate 20 not only makes room for the new battery 29 to enter, but also prevents the sealing plate 20 from obstructing the advancement of the new battery 29. Simultaneously, the old battery 29 in the battery compartment 19, pushed by the new battery 29, is pushed out from the other side of the compartment 19. During this process, the old battery 29 contacts the barrier 35. Because the barrier 35 is connected to the hinge shaft via a coil spring, it automatically opens when subjected to external force.This design ensures that the old battery 29 can be smoothly ejected without being obstructed by the baffle 35. When the external force disappears, the coil spring automatically resets the baffle 35, resealing the battery compartment 19. This design of the sealing plate 20 and baffle 35 not only seals the battery compartment 19 but also, through a clever mechanical structure, enables automated opening and closing during battery 29 replacement. The design of the first inclined surface 21 allows the sealing plate 20 to automatically move out of the way when a new battery 29 is inserted, while the combination of the coil spring and hinged shaft ensures that the baffle 35 automatically opens and resets when the old battery 29 is ejected. This design not only improves the efficiency of battery 29 replacement but also reduces the possibility of mechanical failure, providing a reliable guarantee for the efficient operation of the drone 3. Through this innovative sealing and automatic opening mechanism, this solution ensures the sealing of the battery compartment 19 while enabling rapid battery 29 replacement, significantly improving the efficiency and endurance of the drone 3. This design is particularly suitable for drone 3 applications where frequent battery 29 replacement is required, providing important technical support for the automated operation of the drone 3.

[0066] like Figure 7As shown, in this embodiment, the top of the docking chamber 1 is further provided with a first guide rail 25, which is parallel to the drone 3. A first motorized slide 26 is mounted on the first guide rail 25, which slidably engages with it. A second guide rail 27 is fixedly connected to the top of the first motorized slide 26, which is perpendicular to the first guide rail 25. A second motorized slide 28 is slidably mounted on the second guide rail 27, which slidably engages with it. The storage box 17 is mounted on the second motorized slide 28. It should be noted that a movable storage box 17 structure is designed to address the potential interference of the storage box 17 with the drone 3 during landing and to ensure precise alignment of the storage box 17 with the battery compartment 19 during battery 29 replacement. This structure, through the combination of the motorized slide and the guide rail, enables flexible movement of the storage box 17, significantly improving system reliability and operational convenience. Specifically, the top of the docking chamber 1 is provided with a first guide rail 25, which is parallel to the parking direction of the drone 3. A first motorized slide 26 is mounted on the first guide rail 25, which slidably engages with it. A second guide rail 27 is fixedly connected to the top of the first motorized slide 26, which is perpendicular to the first guide rail 25. A second motorized slide 28 is slidably connected to the second guide rail 27, and the storage box 17 is mounted on the second motorized slide 28. This design allows the storage box 17 to move in two directions: along the first guide rail 25, the first motorized slide 26 moves on the first guide rail 25, driving the entire storage box 17 parallel to the drone 3. Along the second guide rail 27, the second motorized slide 28 moves on the second guide rail 27, allowing the storage box 17 to be fine-tuned perpendicular to the drone 3. This dual-guide rail and dual motorized slide design allows the position of the storage box 17 to be precisely controlled. During battery 29 replacement, the positions of the first motorized slide 26 and the second motorized slide 28 are adjusted to ensure that the second opening 32 of the storage box 17 is precisely aligned with the entrance to the drone 3's battery compartment 19. This alignment mechanism not only improves the reliability of battery 29 replacement but also reduces mechanical failures caused by misalignment. In addition, when the drone 3 lands, the storage box 17 can be moved to a farther position by the first electric slide 26 to avoid interfering with the landing of the drone 3. This design ensures that the drone 3 will not be obstructed by the storage box 17 during the landing process, thereby improving the overall safety of the system. Through the design of double guide rails and double electric slides, the position of the storage box 17 can be precisely adjusted to ensure that the second opening 32 is precisely aligned with the entrance of the battery compartment 19 of the drone 3. This design significantly improves the reliability and efficiency of battery 29 replacement. When the drone 3 lands, the storage box 17 can be moved to a farther position to avoid interfering with the landing of the drone 3. This design improves the overall safety of the system and ensures the smooth operation of the drone 3 during the landing process. The use of the electric slide makes the movement of the storage box 17 fully automated, reducing manual intervention.This design not only improves operational convenience but also enhances the overall efficiency of the system. By adjusting the position of the electric slide, the storage box 17 can adapt to different models of drones 3 and battery compartment 19 designs, increasing the system's versatility and adaptability. Through this innovative mechanism for moving the storage box 17, the present invention not only resolves interference issues during drone 3 landing but also improves the reliability of battery 29 replacement through a precise alignment mechanism. This design provides important technical support for automated battery 29 replacement in drones 3, significantly improving the efficiency and endurance of drones 3. Furthermore, to enhance the accuracy of alignment between the second opening 32 and the drone 3's battery compartment 19, a comprehensive solution combining sensor technology and a mechanical guide mechanism can be employed. A specific implementation method is as follows: High-precision positioning sensors are installed on both the storage box 17 and the drone 3's battery compartment 19 to monitor their relative position in real time. These sensors can be photoelectric sensors, laser sensors, or visual sensors (such as cameras). Using the position information captured by the sensors, the controller precisely adjusts the positions of the first and second electric slides 26 and 28 to ensure proper alignment of the second opening 32 with the battery compartment 19.

[0067] like Figure 5As shown, in this embodiment, a recycling bin 36 is also provided on the top of the docking chamber 1. The recycling bin 36 is located on the side of the drone 3 away from the storage bin 17 and can be driven by a movable assembly to move across the top of the docking chamber 1. It should be noted that to improve the stability and safety of the drone 3 battery 29 replacement process and to effectively recycle the old batteries 29, a recycling bin 36 is provided on the top of the docking chamber 1. The recycling bin 36 is located on the side of the drone 3 away from the storage bin 17 and is driven by a movable assembly to move across the top of the docking chamber 1. This design not only provides a dedicated recycling area for old batteries 29 but also plays an important auxiliary role in the battery 29 replacement process. The recycling bin 36 moves in the same manner as the storage bin 17, using a guide rail. When the drone 3 battery 29 is replaced, the old battery 29 is ejected from the battery compartment 19 and falls directly into the recycling bin 36. The presence of the recycling box 36 ensures that the old batteries 29 can be centrally managed and recycled, preventing the old batteries 29 from being scattered randomly on the top of the docking room 1, and improving the safety and convenience of the operation. This centralized recycling method facilitates the subsequent unified charging, testing or processing of the old batteries 29, further optimizing the battery 29 management process. During the process of replacing the battery 29, after the recycling box 36 is moved to the other side of the drone 3, it can support the other side of the drone 3. Since the drone 3 may produce slight displacement due to external forces (such as the propulsion force of the new battery 29) during the battery 29 replacement process, the support function of the recycling box 36 can effectively prevent the movement of the drone 3 and ensure the stability of the battery 29 replacement process. This design limits the shaking of the drone 3 by physical means, improves the reliability of battery 29 replacement, and is particularly important in unmanned automation scenarios.

[0068] like Figure 1 As shown, in this embodiment, an electric switch door 2 is provided on one side of the parking room 1. It should be noted that when the mechanical dog 5 goes out, the electric switch door 2 will automatically open.

[0069] The working principle of the present invention is:

[0070] Docking of drone 3 and cargo transfer: After drone 3, carrying cargo, arrives above docking chamber 1, it uses the QR code on the inductive door to assist positioning. Using a high-precision satellite positioning system (such as GPS or Beidou Navigation System) combined with visual recognition technology, it docks precisely at the designated location on the top of docking chamber 1. The inductive door automatically opens upon arrival. The clamp 16 on drone 3's bottom releases, allowing the cargo to drop from the discharge port 4 into the collection box 6 inside docking chamber 1, housed within the robotic dog 5. The loading plate 7 inside the collection box 6 moves downward under the weight of the cargo, driving the first rotating shaft 10 clockwise via drive components (such as the conveyor belt 12 and connecting rods). The half gear 13 on the first rotating shaft 10 meshes with the rack 15, driving the sealing door 14 horizontally to seal the collection box 6. At this point, the flexible sealing strip on the edge of the sealing door 14 tightly fits the opening of the collection box 6, preventing the cargo from falling during transport and protecting it from the external environment. The placement plate 7 inside the collection box 6 is equipped with pressure sensors and weight sensors to monitor the weight and placement status of the goods in real time. The sensors feed this information back to the base station control system to ensure the reliability of the goods handover process.

[0071] Starting and Navigating the Robot Dog 5: After receiving the package in the collection box 6, the Robot Dog 5 plans a path using autonomous navigation and obstacle avoidance technologies (such as LiDAR and vision sensors) to avoid obstacles and pedestrians within the residential area. The Robot Dog 5 also features intelligent elevator interaction, connecting to the elevator control system via a wireless communication module to enable autonomous elevator travel. When the Robot Dog 5 arrives at the patient's door with the package, it notifies the patient by knocking on the door or sounding a notification. The display on the back of the Robot Dog 5 displays relevant information (such as the order number and the delivered item). The Robot Dog 5 is also equipped with an intelligent voice interaction module for simple communication with the patient to confirm the delivery status.

[0072] Cargo removal and opening of sealed door 14: The patient opens sealed door 14, and rack 15 moves in the opposite direction of sealed door 14, driving half gear 13 to rotate counterclockwise, causing placement plate 7 to rise, lifting the cargo to a higher position for easier access by the patient. After sealed door 14 is opened, the patient removes the cargo, and robot dog 5 returns to docking room 1 to wait.

[0073] Replacing Drone 3's Battery 29: When Drone 3 reaches the designated location at the top of docking chamber 1 and detects that the battery 29 is low on charge, the battery 29 replacement mechanism activates. The push plate 30 of the electric push rod 24 enters through the second opening 32 of the storage box 17, pushing the spare battery 29 stacked on the top of the tray 33 out of the first opening 31 and into the battery compartment 19 of Drone 3. The old battery 29 in Drone 3's battery compartment 19 is pushed out from the other side by the new battery 29, landing in the designated recycling location at the top of docking chamber 1. The recycling bin 36, using moving components (such as an electric slide and guide rails), moves to the other side of Drone 3, collecting the old batteries 29 and preventing them from being scattered.

[0074] The battery 29 is replaced: the electric push rod 24 is reset, and the support plate 33 moves upward under the elastic force of the second spring 23, pushing the next spare battery 29 to the top of the storage box 17, preparing for the next battery 29 replacement.

[0075] The circuits, electronic components and modules involved are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.
