Description

Technical Field

[0001] This invention relates to the field of drone logistics technology, specifically to a rooftop receiving device for drone logistics and personnel transportation. Background Technology

[0002] With the rapid development of drone logistics technology, its application scenarios are expanding from point-to-point delivery of small packages to more large-scale and commercially valuable urban building delivery. In existing technologies, drone logistics receiving devices are mostly designed for small and medium-sized goods and are often installed in windows or balconies on the side of buildings. For example, Chinese Patent CN120534740A discloses a "drone logistics window receiving device" that, through a retractable receiving platform and a robotic arm gripping structure, enables the guidance of drones and the reception of goods within a limited window space, effectively solving the problem of poor adaptability of traditional fixed platforms.

[0003] However, existing technology has significant limitations when delivering large items (such as building materials, large equipment boxes, and bulk daily necessities) to the rooftop areas of high-rise buildings in cities: 1. Insufficient load-bearing capacity: The window receiving device has a lightweight structure, and its telescopic mechanism, transmission components and receiving platform have limited load-bearing capacity, which cannot meet the requirements for the safe landing and storage of large goods.

[0004] 2. Space and stability limitations: The limited space at the window location restricts the deployment range and structural strength of the device. While rooftop platforms offer the advantage of open space, existing window receiving device structures cannot utilize this advantage to form a stable, large-area receiving plane, making it difficult to cope with the significant impact and off-center loads that may occur when large goods are dropped.

The second landing pad, formed by the extended carrying container, provides a flexible secondary working surface, which can be used for secondary sorting or specialized handling of special cargo. This design leverages the openness of the rooftop to ensure the safety and stability of heavy-load landings, while also optimizing and diverting the workflow through a double-layer structure. The beneficial effects are: it forms an independent and complementary double-layer connection operation surface, which solves the problems of low efficiency and mutual interference when a single platform is used to receive complex goods.

[0018] 3.

The limiting mechanism is not a simple fixed limit, but can actively move and automatically stack and gather the goods in the box when the carrier box receives the goods. The beneficial effects are: it has intelligent cargo sorting function, which not only optimizes the utilization of space inside the container and reduces the risk of jamming or damage caused by cargo tipping or scattering, but also improves the reliability and processing efficiency of the entire receiving device under continuous and batch operation.

[0024] Example 1: Reference Figures 1-6 The present invention discloses a rooftop receiving device for drone logistics and personnel transportation, comprising: To achieve efficient classification and storage of drone cargo and intensive use of rooftop space, in this embodiment: a receiving cabinet 1 is installed on the rooftop of a building.

The top of the horizontal section of the receiving cabinet 1 is provided with multiple loading ports. The middle of the first landing pad 11 is provided with a square hole that matches the loading port of the receiving cabinet 1. Two baffles 12 are slidably installed at the top of the horizontal section of the receiving cabinet 1 through an electric guide rail.

In order to guide the drone to land accurately on the roof and drop low-profile goods, in this embodiment: the carrier box 21 is slidably disposed in the horizontal cavity 3, the top of the carrier box 21 is provided with a second landing pad 22, the top of the carrier box 21 is provided with a delivery port, the middle of the second landing pad 22 is provided with a square hole that matches the delivery port of the carrier box 21, and the open opening of the carrier box 21 is provided with a box door 24 through an elastic locking mechanism; In order to achieve stable and precise extension and retraction of the carrier box within the horizontal cavity 3, in this embodiment: a drive mechanism is used to adjust the carrier box 21 to enter and exit the horizontal cavity 3. The drive mechanism includes: a first servo motor 31, which is mounted on the outer wall of the carrier box 21 near the vertical cavity 2 via a plate. The output shaft of the first servo motor 31 is provided with a gear 32. A rack 33 is provided on the bottom wall of the horizontal cavity 3. The gear 32 and the rack 33 are meshed. Two linear guide rails 34 are provided on the bottom wall of the horizontal cavity 3. The carrier box 21 is mounted on the top of the slider of the two linear guide rails 34. To achieve automatic stacking of internal goods during the pulling and pulling movement of the carrying box 21, in this embodiment: a limiting mechanism is set inside the transverse cavity 3. The limiting mechanism includes: a rotating shaft 43; first support blocks 41 are respectively provided on opposite side walls of the transverse cavity 3; second support blocks 42 are respectively provided on opposite side walls of the transverse cavity 3; rectangular holes 23 are provided on opposite sides of the carrying box 21; the first support blocks 41 are slidably installed in the rectangular holes 23; the second support blocks 42 are located outside the carrying box 21; and the rotating shaft 43 is rotatably installed on the same side of the transverse cavity 3. Between the first support block 41 and the second support block 42, a limit plate 44 is provided at one end of the rotating shaft 43 near the box door 24. The two limit plates 44 are perpendicular to each other. A second servo motor 45 is provided on the side wall of one of the second support blocks 42. The output shaft of the second servo motor 45 is fixedly connected to the adjacent rotating shaft 43 through a coupling. A transmission mechanism is provided between the two rotating shafts 43.

The elastic locking structure includes a U-shaped locking rod 61. Cabinet door 4 and box door 24 are respectively rotatably installed in the vertical cavity 2 and the opening of the carrier box 21 by torsion springs. U-shaped locking rods 61 are provided on the side walls of cabinet door 4 and box door 24. Electric actuators 62 are provided in the carrier box 21 and receiving cabinet 1. The output end of electric actuator 62 is matched with U-shaped locking rods 61.

[0025] To achieve efficient and safe personnel transfer in scenarios such as drone logistics reception, rooftop equipment maintenance, emergency handling, and manual cargo verification, this invention designs a dedicated personnel transfer area on the rooftop platform, and integrates it with the functions of the first helipad 11 and the receiving cabinet 1. The core of personnel transfer lies in using drones as vertical transport tools to transport professionals from the ground or other safe take-off and landing points to the rooftop receiving platform. To this end, this invention specifically designates and marks an independent personnel transfer helipad next to the first helipad 11. This helipad meets higher safety standards than cargo helipads in terms of size, structural strength, and surface anti-slip treatment, and is equipped with high-brightness guide lights and status indicator lights on its surface.

[0026] When a personnel transfer mission is scheduled, the building's control center or authorized personnel can send instructions through the system. First, the guide lights on the personnel transfer helipad activate, emitting specific light signals to provide precise visual landing guidance for the drone. The drone carrying personnel (which must be a multi-rotor or compound-wing manned drone compliant with safety regulations) receives a wireless clearance signal from the rooftop device, flies along the guided route to the personnel transfer helipad, and lands stably. To ensure absolute safety, after the drone lands and its rotors stop spinning, the personnel are escorted safely off the helipad and into the rooftop work position. The entire transfer process involves data interaction and coordination between the device's main control system and the drone's flight control system, enabling rapid and automated point-to-point personnel transfer from the air to the rooftop platform. This significantly expands the device's application capabilities and response speed in complex logistics tasks and integrated building management.

[0027] The working principle and usage process of this invention are as follows: First, to guide the drone to land accurately on the rooftop and drop high-sized cargo, the first landing pad 11 provides a landing platform for the drone. Two baffles 12 above it can slide via electric guide rails. When the drone approaches, several signal transmitters installed around the first landing pad 11 are activated, sending landing coordinates and attitude correction signals to the drone. After the drone lands, the two baffles 12 installed on both sides of the first landing pad 11 align and close along the electric guide rails, completing the physical positioning of the drone's landing gear. Simultaneously, photoelectric sensors embedded at the edge of the first landing pad 11 detect that the drone is in a stable state and trigger a cargo drop permission signal. Upon receiving the signal, the drone releases its loaded cargo, which is accurately placed into the designated vertical cavity 2 through the square hole in the middle of the first landing pad 11 and the cargo inlet at the top of the horizontal section of the receiving cabinet 1 below.

[0028] To guide the drone to land precisely on the rooftop and drop low-profile goods, the carrier box 21 located within the transverse cavity 3 begins operation. Its drive mechanism activates, and the first servo motor 31 drives the gear 32 to rotate. The gear 32 meshes with a rack 33 fixed to the bottom wall of the transverse cavity 3, driving the entire carrier box 21 to slide smoothly along two linear guide rails 34, extending it outward from the transverse cavity 3. Once extended, the second landing pad 22 on its top is exposed, serving as a take-off and landing platform for the drone. The drone can drop goods through the square hole in the center of the second landing pad 22 into the delivery port on top of the carrier box 21. Simultaneously, during the pulling motion of the carrier box 21, a limiting mechanism within the transverse cavity 3 automatically aligns the internal goods during this process. Before the carrier box 21 moves outward, the second servo motor 45 drives a rotating shaft 43 to rotate. The synchronous belt 52, which is wound between two pulleys 51, drives another rotating shaft 43 to rotate synchronously. This causes the two vertically opposite limiting plates 44, which are fixed to the two rotating shafts 43 near the end of the box door 24, to rotate 90 degrees and be positioned in the channel of cargo movement. In conjunction with the sliding of the carrier box 21, the cargo is blocked and moves into the carrier box 21. The drone then drops the next low-profile cargo into the carrier box 21. Then the limiting mechanism resets, and the carrier box 21 retracts into the horizontal cavity 3 under the action of the drive mechanism. The box door 24 of its open opening is also automatically locked and controlled to open through a torsion spring and an elastic locking mechanism composed of a U-shaped locking rod 61 and an electric actuator 62.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
