Description

Technical Field

[0001] This invention relates to the field of drone start-stop technology, and in particular to a rapid take-off and landing system and method for drones. Background Technology

[0002] With the rapid development and widespread application of drone technology across various fields, especially in large-scale swarm applications, the importance of unmanned systems is increasingly prominent. This requires drones to have the ability to rapidly swarm and collaboratively execute tasks. As a core component of unmanned systems, one of the core tasks of drone hangars is to support the rapid and efficient swarm deployment and response of drones. However, existing drone hangar technologies have significant shortcomings in meeting this critical requirement.

[0003] Common solutions on the market fall into two main categories: The first is the "one hangar, one drone" type. While this design allows for relatively quick response for a single drone, it necessitates deploying numerous hangars when large-scale drone swarms are required, leading to high system costs, a large footprint, poor deployment flexibility, and easy target exposure, making it unsuitable for the rapid mobility and stealth requirements of modern battlefields. The second is the less common "one hangar, multiple drones" type. These hangars typically employ a drawer-type horizontal telescopic structure to accommodate multiple drones. Although this reduces the number of hangars to some extent, the drawer-type structure's deployment and retrieval process is time-consuming, failing to meet the extremely short response time requirements for rapid drone swarm takeoff.

[0004] Meanwhile, the complex drawer-type mechanical structure not only makes maintenance difficult but also leads to inefficient use of the hangar's internal space, further limiting the number of drones a single hangar can accommodate or increasing the overall volume of the hangar. Therefore, designing a lifting structure suitable for hangars that can efficiently achieve "one hangar, multiple drones" storage, significantly improve space utilization, simplify the mechanical structure, and ensure that drone swarms can achieve rapid response and takeoff after receiving mission commands is a key technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid take-off and landing system and method for unmanned aerial vehicles (UAVs) to address the above-mentioned shortcomings, thereby solving the problem of the lack of efficient storage structures for multiple UAVs in a single warehouse in the prior art.

[0006] This invention is achieved through the following scheme: A rapid lifting and lowering system for unmanned aerial vehicles (UAVs) includes a UAV, a power mechanism, a transmission mechanism, and a guiding mechanism. The power mechanism is connected to the transmission mechanism. The UAV has a guide rib on its circumferential position, and the guiding mechanism has a guide groove that cooperates with the guide rib. The transmission mechanism has a support plate for supporting the UAV. Multiple support plates are arranged along the length of the transmission mechanism, and under the action of the power mechanism, the support plates can lift and lower multiple UAVs synchronously.

[0007] Based on the structure of the above-mentioned rapid take-off and landing system for unmanned aerial vehicles (UAVs), the UAV includes a fuselage, arms, motors, and propellers. The arms are arranged around the fuselage, the motors are located at the ends of the arms away from the fuselage, the propellers are located at the output ends of the motors, and the guide ridges are symmetrically arranged on both sides of the fuselage. At least two guide ridges are provided on each side of the fuselage. The guide ridges are arranged parallel to each other.

[0008] Based on the structure of the above-mentioned rapid take-off and landing system for unmanned aerial vehicles, the power mechanism includes a power motor, a reducer, and a coupling; the output shaft of the power motor is connected to the coupling through the reducer, and is connected to the transmission mechanism through the coupling.

[0009] Based on the structure of the aforementioned rapid take-off and landing system for unmanned aerial vehicles, the transmission mechanism includes an upper support, a driven shaft, a lower support, a drive shaft, and a transmission chain. The upper support is provided with a first bearing housing that mates with the driven shaft, and the driven shaft is housed within the first bearing housing. The lower support is provided with a second bearing housing that mates with the drive shaft, and the driven shaft is housed within the second bearing housing. The transmission chain is sleeved between the driven shaft and the drive shaft. The drive shaft is connected to a coupling.

[0010] Based on the structure of the above-mentioned rapid take-off and landing system for unmanned aerial vehicles, two parallel first sprockets are arranged on the drive shaft, and two parallel second sprockets are arranged on the driven shaft. The positions of the two first sprockets are matched with the positions of the two second sprockets. A transmission chain is arranged between the first sprockets and the second sprockets, for a total of two sets of transmission chains.

[0011] Based on the structure of the above-mentioned rapid take-off and landing system for unmanned aerial vehicles, a limiting groove is provided in the circumferential position of the transmission chain. The two ends of the limiting groove are respectively connected to the upper support and the lower support, and the limiting groove engages the transmission chain therein.

[0012] Based on the structure of the above-mentioned rapid take-off and landing system for unmanned aerial vehicles, a pin is provided on the end of the pallet near the transmission chain, and a pin hole is provided on the transmission chain, with the pin engaging in the pin hole.

[0013] Based on the structure of the above-mentioned rapid take-off and landing system for unmanned aerial vehicles, a position sensor for detecting the position of the tray is provided on the upper support; and a photoelectric sensor for detecting the presence of the unmanned aerial vehicle is provided at the upper end of the guide mechanism.

[0014] Based on the structure of the above-mentioned rapid take-off and landing system for unmanned aerial vehicles, the guiding mechanism includes two sets of guide rods arranged opposite each other, and the guide groove is disposed on the guide rods arranged opposite each other. The distance between the paired guide rods matches the position of the guide protrusions disposed on opposite sides of the fuselage.

[0015] This solution also provides a method for rapid takeoff and landing of drones, including a drone takeoff method: Step A1: Upon receiving the takeoff command, the photoelectric sensor confirms whether there is a drone at the takeoff location. If no drone is detected, the motor activates, and the transmission chain drives the tray upwards until the position sensor detects the tray and the photoelectric sensor detects the presence of a drone. At this point, the motor stops. Step A2: The drone takes off, the counter increments by one, and if the photoelectric sensor detects no drone again, the motor activates, the transmission chain moves, and the tray moves upward until the position sensor detects the tray and the photoelectric sensor detects the presence of a drone. The drone takes off, the counter increments by one, and the count continues until the total number of drones taken off is reached. It also includes drone landing methods: Step B1: The drone has completed takeoff. Load the drone and the photoelectric sensor confirms whether the drone is at the takeoff location. If the drone is present, the power motor will activate and the transmission chain will drive the tray downwards until the position sensor detects the tray. At this point, the lifting stops and the counter increments by one. Step B2: Load the drone again. The photoelectric sensor confirms again whether there is a drone at the takeoff position. If there is a drone, the power motor will start, and the transmission chain will drive the tray downward until the position sensor detects the tray. At this time, the lifting stops, and the counter increments by one. This continues until the number of drones loaded is complete.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This invention incorporates multiple support plates in the transmission mechanism to support multiple drones. Through the action of the power mechanism, multiple drones can be driven to move synchronously. At the same time, the guiding mechanism is equipped with guide grooves, and guide protrusions are installed on the drones, so that multiple drones can rise and fall stably during the movement, ensuring the safety of individual drones while multiple drones are rapidly rising and falling.

[0017] 2. This solution enables multiple drones in one warehouse, reducing equipment costs for unmanned drone cluster deployment; it also improves the flexibility of the equipment. 3. This solution has high space utilization and a compact structure. Attached Figure Description

[0023] Example 1 like Figures 1-3As shown, the present invention provides a technical solution: A rapid lifting and lowering system for unmanned aerial vehicles (UAVs) includes a UAV 1, a power mechanism 2, a transmission mechanism 3, and a guide mechanism 4. The power mechanism 2 is connected to the transmission mechanism 3. A guide rib 15 is provided on the circumferential position of the UAV 1. A guide groove 42 that cooperates with the guide rib 15 is provided in the guide mechanism 4. A support plate 5 for supporting the UAV is provided in the transmission mechanism 3. Multiple support plates 5 are provided along the length of the transmission mechanism 3. Under the action of the power mechanism 2, the support plates 5 can lift and lower multiple UAVs 1 synchronously.

[0024] Based on the above structure, multiple support plates 5 are set in the transmission mechanism 3 so that they can carry multiple drones. Through the action of the power mechanism 2, multiple drones 1 can be driven to move synchronously. At the same time, a guide groove 42 is set in the guide mechanism 4, and a guide protrusion 15 is set on the drone 1 so that multiple drones 1 can be raised and lowered stably during the movement, ensuring the safety of a single drone 1 while multiple drones 1 are rapidly rising and falling.

[0025] As an example, the drone 1 may include a fuselage 11, arms 12, motors 13 and propellers 14. The arms are arranged around the fuselage 11, the motors 13 are arranged at the ends of the arms away from the fuselage 11, the propellers are arranged at the output ends of the motors 13, and guide ribs 15 are symmetrically arranged on both sides of the fuselage 11. At least two guide ribs 15 are provided on each side of the fuselage 11. The guide ribs 15 are arranged parallel to each other.

[0026] Based on the above structure, guide strips 15 are provided on both sides of the fuselage 11 of the UAV 1. These guide strips 15 can cooperate with the guide strips 15 in the guide mechanism 4 to quickly achieve stable guidance of a single UAV 1, enabling it to rise and fall in a specified direction.

[0027] As an example, the power mechanism 2 may include a power motor 21, a reducer 22, and a coupling 23; the output shaft of the power motor 21 is connected to the coupling 23 through the reducer 22, and is connected to the transmission mechanism 3 through the coupling 23.

[0028] Based on the above structure, the power of the motor 21 can be output to the transmission mechanism 3 stably and efficiently through the reducer 22 and coupling 23, which can avoid the situation where the motor 21 is damaged due to excessive resistance.

[0029] As an example, the transmission mechanism 3 may include an upper support 31, a driven shaft 32, a lower support 33, a drive shaft 34, and a transmission chain 35; the upper support 31 is provided with a first bearing seat 36 that mates with the driven shaft 32, and the driven shaft 32 is disposed in the first bearing seat 36; the lower support 33 is provided with a second bearing seat 37 that mates with the drive shaft 34, and the driven shaft 32 is disposed in the second bearing seat 37; the transmission chain 35 is sleeved between the driven shaft 32 and the drive shaft 34; the drive shaft 34 is connected to the coupling 23.

[0030] Based on the above structure, the power source rotates the coupling 23, which in turn drives the drive shaft 34 to rotate, ultimately causing the transmission chain 35 to rotate, enabling the pallet 5 driven by the transmission chain 35 to move rapidly.

[0031] As an example, two parallel first sprockets are provided on the drive shaft 34, and two parallel second sprockets 38 are provided on the driven shaft 32. The positions of the two first sprockets are matched with the positions of the two second sprockets 38. A transmission chain 35 is provided between the first sprockets and the second sprockets 38, for a total of two sets of transmission chains 35.

[0032] Based on the above structure, the two sets of transmission chains 35 in this solution can more stably drive the pallet 5. Since the two first sprockets rotate synchronously, the two transmission chains 35 can move synchronously, so that the pallet 5 always remains horizontal, preventing the drone 1 from tilting during movement, and enabling the drone 1 to rise and fall more smoothly.

[0033] As an example, a limiting groove 39 is provided in the circumferential position of the transmission chain 35. The two ends of the limiting groove 39 are connected to the upper bracket 31 and the lower bracket 33 respectively. The limiting groove 39 locks the transmission chain 35 in place. The limiting groove 39 can prevent the transmission chain 35 from swaying left and right, thereby ensuring the stability of the lifting process.

[0034] As an example, a pin is provided on the end of the pallet 5 near the drive chain 35, and a pin hole is provided on the drive chain 35, in which the pin is engaged; the pallet 5 is driven to move stably through the drive chain 35.

[0035] As an example, a position sensor 6 for detecting the position of the tray 5 is provided on the upper bracket 31; and a photoelectric sensor 7 for detecting the presence of the drone 1 is provided at the upper end of the guide mechanism 4. Based on the above structure, the position sensor 6 detects whether the pallet 5 has reached the takeoff or landing position. When the position sensor 6 detects an object, it indicates that the pallet 5 has moved into position, and the lifting mechanism stops moving. The photoelectric sensor 7 is used to detect whether there is a drone 1 at the takeoff position. When the sensor detects an object, it indicates that there is a drone 1 at the current takeoff position, and the lifting mechanism cannot continue to rise. After the drone 1 takes off, and the sensor detection result returns to no object, the lifting mechanism resumes operation, and the pallet 5 continues to move along the chain along the chain running trajectory to the back, while simultaneously sending the next drone 1 to the takeoff position to wait for takeoff.

[0036] As an example, the guide mechanism 4 may include two sets of guide rods 41 arranged opposite each other, and guide grooves 42 are disposed on the guide rods 41 arranged opposite each other. The distance between the pair of guide rods 41 matches the position of the guide protrusions 15 arranged on opposite sides of the body 11.

[0037] Based on the above structure, the drone 1 can be smoothly engaged with the paired guide rods 41 to achieve drone 1 guidance.

[0038] In this design, the drone 1 is placed on the tray 5. When the motor 13 runs, it can move the tray 5, thereby moving the drone 1 and achieving lifting and lowering (the tray 5 on which the drone 1 is placed is only in a straight line). Since multiple trays 5 are installed, multiple drones 1 can be placed at the same time, thus enabling multiple drones 1 to lift and lower simultaneously.

[0039] Example 2 This invention provides a technical solution: A method for rapid takeoff and landing of a drone, comprising a takeoff method for drone 1: Step A1: After receiving the takeoff command, the photoelectric sensor 7 confirms whether there is a drone 1 at the takeoff location. If no drone 1 is detected, the power motor 21 is activated and the transmission chain 35 drives the tray 5 upward until the position sensor 6 detects the tray 5 and the photoelectric sensor 7 detects the presence of drone 1. Then the power motor 21 stops operating. Step A2: Drone 1 takes off, the counter increments by one, and the photoelectric sensor 7 detects no drone 1 again. Then the power motor 21 is activated, and the transmission chain 35 drives the tray 5 upward until the position sensor 6 detects the presence of the tray 5 and the photoelectric sensor 7 detects the presence of drone 1. Drone 1 takes off, the counter increments by one, until the number of drone 1 take-offs is completed (keeping the current take-off completed).

[0040] It also includes the drone landing method: Step B1: The drone 1 has completed takeoff. The drone 1 is loaded. The photoelectric sensor 7 confirms whether the drone 1 is at the takeoff position. If the drone 1 is there, the power motor 21 is activated and the transmission chain 35 drives the tray 5 downward until the position sensor 6 detects the tray 5. At this time, the lifting stops and the counter counts by one. Step B2: Load drone 1 again. Photoelectric sensor 7 reconfirms whether drone 1 exists at the takeoff position. If drone 1 exists, the power motor 21 is activated, and the transmission chain 35 drives the tray 5 downward until the position sensor 6 detects the presence of tray 5. At this point, the lifting stops, and the counter increments by one until the number of drones loaded is complete.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
