Description

Technical Field

[0001] This utility model relates to the field of aerospace technology, and in particular to a mobile and fixed unmanned aerial vehicle (UAV) airport. Background Technology

[0002] Drone airports are used for storing and retrieving drones. Currently, drone airports are either fixedly deployed at specific operational locations to form fixed airports, or mobile airports built on vehicles based on their characteristics. A single drone airport cannot simultaneously function as both a fixed and mobile airport, limiting its application scenarios. Furthermore, during vehicle movement, swaying and collisions can occur, requiring locking structures to secure the drones and prevent damage from impacts with the airport's internal structure or other equipment. Current locking structures are relatively complex and cannot meet the requirements for efficient and reliable locking. Summary of the Invention

[0003] Based on the above analysis, the present invention aims to provide a mobile and fixed unmanned aerial vehicle (UAV) airport to solve the problems that current UAV airports cannot simultaneously accommodate both fixed and mobile configurations, and that the airport locking structure cannot meet the requirements for efficient and reliable locking.

[0004] The objective of this utility model is mainly achieved through the following technical solutions:

[0005] A mobile and fixed unmanned aerial vehicle (UAV) airport includes a mobile carrier device and an airport unit; the airport unit is disposed on the mobile carrier device.

[0006] The airport unit includes a parking apron, fixed components, and a support base, with the support base located at the lower part of the airport unit;

[0007] The fixing component includes a claw hook and a claw hook groove; the claw hook groove is located at the bottom of the landing pad; the claw hook can extend out of the claw hook groove to hook the drone's landing gear and lock the drone.

[0008] Furthermore, the claw hook is rotatable; when the claw hook rotates to 15°-165°, the claw hook can extend from the claw hook groove to hook the tripod, thereby locking the drone; when unlocking, the claw hook reverses and disengages from the tripod, thereby releasing the drone.

[0009] Furthermore, the airport unit also includes a propeller assembly; the propeller assembly is used to move the propellers of the UAV that exceed the width of the airport unit into the airport unit.

[0010] Furthermore, there are two propeller assemblies; the two propeller assemblies are arranged at a distance from each other on one side of the landing pad, and the two propeller assemblies are used to actuate the same propeller blade of the UAV.

[0011] Furthermore, the propeller assembly includes propeller components and a propeller drive structure; when the propeller assembly is stored, the two propeller components are horizontally arranged; when the propeller assembly propels the propeller, the propeller components rotate in a plane perpendicular to the propeller blade, and the rotation is achieved by the propeller drive structure; the two propeller components rotate in opposite directions.

[0012] Furthermore, the blade has a blade rotation trajectory, and the projection of the blade rotation trajectory on the helipad has a first intersection point and a second intersection point with the inner edge line of the helipad. When the two propeller components are in a vertical state, their projections on the helipad are located at the first intersection point and the second intersection point, respectively.

[0013] Furthermore, four claw hooks are provided, which are symmetrically arranged in the middle of the landing pad, and the openings of the claw hooks face outwards towards the landing gear.

[0014] Furthermore, the claw hook is hook-shaped with an arc-shaped interior, and the shape of the arc is adapted to the shape of the tripod.

[0015] Furthermore, the airport unit also includes a centering component; the centering component includes an X-axis centering part and a Y-axis centering part; there are two X-axis centering parts, which are arranged in parallel and can move towards each other simultaneously;

[0016] The Y-axis centering component has two parts, which are arranged in parallel and can move towards each other simultaneously.

[0017] Furthermore, the airport unit also includes an apron lifting assembly; the apron lifting assembly includes a drive screw structure, a drive chain, and a drive motor.

[0018] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0019] (1) The airport unit of this utility model is placed on a mobile carrier device, so that the fixed airport has the function of a mobile airport. The bottom of the airport unit is provided with multiple support seats, so that the airport unit can be stably placed on a conventional rigid base as a fixed airport. Therefore, the airport of this utility model has the functions of both a fixed airport and a mobile airport, which improves the flexibility of the airport, expands the application scenarios of UAV airports, improves the flexibility of the airport and the operating efficiency of UAVs, expands the operating service radius of the airport, and increases the cross-regional operation capability of the airport.

[0020] (2) Compared with the prior art, the fixing component of this utility model uses a claw hook and a claw hook groove, with the claw hook set in the claw hook groove. The claw hook can be retracted into the claw hook groove to prevent interference with the UAV; the claw hook can also extend out of the claw hook groove to hook the UAV's landing gear, thereby locking the UAV. This utility model uses a claw hook to lock the UAV, which is simple in structure and can quickly and efficiently fix the UAV in place, ensuring the stability of the UAV. This ensures that the UAV can be reliably fixed during takeoff and landing and during airport operation, avoiding damage caused by collisions between the UAV and the airport's internal structure or other equipment. The claw hook in this utility model can rotate within the claw hook groove. When rotated to 15°-165°, it can extend out of the claw hook groove to lock, and when rotated in the opposite direction, it can release the lock; when the claw hook rotates to less than 15° and greater than 165°, the claw hook is below the landing pad and does not interfere with the movement of the UAV.

[0021] (3) In this invention, a propeller-shifting component is used to move propeller blades that exceed the width of the airport into the airport interior, thereby making full use of the airport's storage space and avoiding damage to the propeller blades. Compared with the prior art, the propeller-shifting component in this invention can move both foldable and non-foldable propeller blades. Two sets of propeller-shifting components are used for each propeller blade. The two propeller-shifting components are arranged at intervals and opposite each other, rotating sequentially in different directions in a plane perpendicular to the propeller blade to move the propeller blade. When the two propeller-shifting components are in a vertical state, their projections on the apron are respectively located at the first intersection point and the second intersection point of the projection of the propeller blade's rotation trajectory on the apron and the inner edge line of the apron, so as to accurately move the propeller blade. The propeller-shifting component uses carbon fiber rods, which has a lightweight effect.

[0022] (4) The centering component of this utility model is used to center a UAV that has not landed in the center position, thereby reducing the storage volume of the airport, optimizing space utilization, reducing the difficulty of charging and recharging the UAV, and enabling the precise use of components set in specific positions, thus improving the functionality of the airport. The centering component includes an X-axis centering component and a Y-axis centering component, each with a drive structure, so that the X-axis centering component and the Y-axis centering component can be used independently. By having the X-axis centering component and the Y-axis centering component move independently and simultaneously towards each other, the UAV is moved, achieving rapid centering of the UAV in the X-axis and Y-axis directions.

[0023] (5) This utility model has four claw hooks, which are symmetrically arranged in the middle of the landing pad, with the openings facing the direction of the UAV landing gear on the outside. This facilitates accurate gripping of the UAV landing gear or detachment of the UAV landing gear, thereby improving the accuracy and efficiency of operation. The claw hooks are hook-shaped with an arc-shaped interior. The arc shape is adapted to the shape of the UAV landing gear to improve the stability of gripping.

[0024] (6) The helipad lifting assembly in this utility model is used to lower the UAV to the corresponding stored position after the UAV is centered and the propellers are turned on, and to raise the UAV to the takeoff position when the UAV takes off. This utility model uses a transmission motor to drive a transmission chain, which in turn drives a lead screw to raise and lower the helipad.

[0025] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained from what is particularly pointed out in the description and drawings. Attached Figure Description

Detailed Implementation

[0039] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0040] A specific embodiment of this utility model is as follows: Figure 1 As shown, a mobile and fixed unmanned aerial vehicle (UAV) airport is disclosed, including a mobile carrier device 1 and an airport unit 2. The airport unit 2 is disposed on the mobile carrier device 1 and can move with the mobile carrier device 1. Exemplarily, the mobile carrier device 1 in this embodiment is a transport vehicle.

[0041] Airport unit 2 is used to house and store drones 3, provide energy to drones 3, and perform data acquisition, communication, and network relay. Airport unit 2 is designed according to the carrying space requirements of drones 3 and mobile carrier equipment 1.

[0042] Airport unit 2 is placed on mobile support equipment 1, giving fixed airport unit 2 the function of mobile airport unit 2. Exemplarily, airport unit 2 is placed on mobile support equipment 1 using bolt connections. Airport unit 2 has multiple support bases 26 at its bottom, allowing it to be stably placed on a conventional rigid base as a fixed airport. Therefore, the airport in this embodiment combines the functions of a fixed airport and a mobile airport, improving airport flexibility, expanding the application scenarios of UAV airports, increasing airport flexibility and UAV operational efficiency, expanding the airport's operational service radius, and enhancing the airport's cross-regional operational capabilities.

[0043] like Figure 2 and Figure 3As shown, airport unit 2 includes a parking apron 21, a centering component 22, a fixing component 23, and a propeller component 24.

[0044] The landing pad 21 serves as a platform for the UAV 3 to take off, land, park, recharge, and transmit information. The centering component 22 and the fixing component 23 are both located on the landing pad 21, while the propeller assembly 24 is located on the outer side of the landing pad 21.

[0045] like Figure 4 and Figure 5 As shown, the centering component 22 is positioned above the apron 21 to center the UAV 3 that has not landed in the center position, thereby reducing the storage volume of the airport unit 2, optimizing space utilization, reducing the difficulty of charging and recharging the UAV 3, and enabling modules set in specific positions to be used precisely, thus improving the functionality of the airport unit 2.

[0046] The centering component 22 includes an X-axis centering component 221 and a Y-axis centering component 222. The X-axis centering component 221 and the Y-axis centering component 222 are arranged in parallel and symmetrically. Exemplarily, in this embodiment, the Y-axis centering component 222 is located above the X-axis centering component 221. Both the X-axis centering component 221 and the Y-axis centering component 222 are two centering rods.

[0047] The drive structure of the X-axis centering component 221 includes an X-axis transmission belt 2212 and an X-axis motor 2211. The X-axis motor 2211 can drive the X-axis transmission belt 2212 to move. The two ends of the X-axis transmission belt 2212 are connected to the X-axis centering component 221. The X-axis motor 2211 causes the X-axis centering component 221 to move towards each other simultaneously through the X-axis transmission belt 2212, thereby driving the UAV 3 to move and achieving rapid centering of the UAV 3 in the X-axis direction.

[0048] The drive structure of the Y-axis centering component 222 includes a Y-axis transmission belt 2222 and a Y-axis motor 2221. The Y-axis motor 2221 can drive the Y-axis transmission belt 2222 to move. The two ends of the Y-axis transmission belt 2222 are connected to the Y-axis centering component 222. The Y-axis motor 2221 causes the Y-axis centering component 222 to move towards each other simultaneously through the Y-axis transmission belt 2222, thereby driving the UAV 3 to move and achieving rapid centering of the UAV 3 in the Y-axis direction.

[0049] Before the drone 3 lands on the landing pad 21, the X-axis centering component 221 and the Y-axis centering component 222 are deployed; after the drone 3 lands on the landing pad 21, the X-axis centering component 221 and the Y-axis centering component 222 are recovered respectively, so that the main body of the drone 31 is centered in the middle of the landing pad 21.

[0050] like Figure 3 and Figure 5As shown, the fixing component 23 includes a claw hook 231. A claw hook groove 232 is provided at the bottom of the landing pad 21; the claw hook 231 is disposed in the claw hook groove 232. When the claw hook 231 is retracted, the claw hook 231 is at the lower part of the landing pad to prevent interference with the drone; when locked, the claw hook 231 extends out of the claw hook groove, hooks the drone's landing gear, and locks the drone.

[0051] Compared with the prior art, this embodiment uses a claw hook 231 and a claw hook groove 232 to lock the UAV 3. When in use, the claw hook 231 extends out of the claw hook groove 232 and is higher than the landing pad 21. When stored, it is placed under the landing pad 21 to prevent interference. The structure is simple, fast and efficient, and ensures the stability of the UAV 3. It can be reliably fixed during the take-off and landing of the UAV 3 and the operation of the airport unit 2, avoiding damage caused by the UAV 3 colliding with the internal structure of the airport 2 or other equipment.

[0052] Exemplarily, the claw hook 231 rotates within the claw groove and extends out of the claw hook slot 232 to hook the landing gear 32 of the drone 3, thereby locking the drone 3. Exemplarily, the claw hook 231 is equipped with a claw hook motor 2311. Driven by the claw hook motor 2311, when the claw hook 231 rotates to 15°-165°, the claw hook 231 extends out of the claw hook slot 232; when rotated to less than 15° and greater than 165°, the claw hook 231 is located below the landing pad 21, without affecting the centering of the drone 3. During unlocking, the claw hook motor 2311 drives the claw hook 231 to reverse, thereby unlocking and releasing the drone 3.

[0053] As another possible embodiment, the claw hook 231 has a lifting structure. When stored, the claw hook 231 descends to the lower part of the landing pad 21 without affecting the operation of the drone 3. When in use, the claw hook 231 rises to the upper part of the landing pad 21 in the claw hook groove 232, hooks the footrest 32 of the drone 3, and locks the drone 3. When unlocking, the claw hook 231 rises first, disengages from the footrest 32 of the drone 3, and then descends to the lower part of the landing pad 21.

[0054] For example, such as Figure 3 As shown, four claw hooks 231 are provided. Preferably, the claw hooks 231 are symmetrically arranged in the middle of the landing pad 21, with the openings of the claw hooks 231 facing the outer drone landing gear 32, which facilitates accurate attachment to the drone 3 or detachment of the drone 3, improving the accuracy and efficiency of the operation.

[0055] Preferably, the claw hook 231 is hook-shaped with an arc-shaped interior, the arc shape matching the shape of the drone landing gear 32 to improve gripping stability. Due to the need to adapt to the configuration of the mobile airport unit 2, the airport unit 2 cannot exceed the width of the vehicle body. For long-wheelbase drones 3, when the drone 3 lands inside the airport unit 2, the propellers of the drone 3 extending beyond the width of the airport unit 2 need to be moved inside the airport unit 2 to ensure that the drone 3 can be stored inside. In this embodiment, the propeller-moving component 24 can move both the foldable and non-foldable propellers 33. Exemplarily, in this embodiment, the non-foldable propellers 33 of the drone 3 extending beyond the width of the airport unit 2 are moved inside the airport unit 2.

[0056] like Figure 6 and Figure 7 As shown, this embodiment provides two propeller assembly 24 for the movement of the same propeller blade 33. The propeller assembly 24 is located on the outside of the airport unit 2, and the two propeller assemblies 24 are spaced apart and opposite to each other, including a first propeller assembly 24 and a second propeller assembly 24. The first propeller assembly 24 includes a first propeller component 241, which has a first drive structure 2411. The second propeller assembly 24 includes a second propeller component 242, which has a second drive structure 2421.

[0057] In this embodiment, to reduce the weight of airport unit 2, the propeller component is made of carbon fiber rod. The drive structure of the propeller component consists of a propeller motor and a reducer. The carbon fiber rod is connected to the output end of the reducer, and the propeller motor and reducer drive the carbon fiber rod to rotate in a plane perpendicular to the propeller blade 33.

[0058] To prevent interference between the two carbon fiber rods during retraction after propeller deployment, the installation height of the first propeller assembly 24 is different from that of the second propeller assembly 24. For example, the installation height of the first propeller assembly 24 is greater than that of the second propeller assembly 24. It should be noted that, in order for the carbon fiber rods to reach the propeller blades 33, the length of the carbon fiber rods is greater than the height of the propeller blades 33 when the UAV 3 lands on the apron 21 of the airport unit 2. Since the two propeller assemblies 24 are arranged opposite to each other, the rotation direction of the first propeller assembly 241 is opposite to that of the second propeller assembly 242. Figure 9 and Figure 10 As shown, in the stowed state, the first paddle component 241 and the second paddle component 242 are horizontally positioned.

[0059] like Figure 8As shown, in order to ensure that the propeller-shifting component can accurately shift the propeller blade 33, the projection of the rotation trajectory of the propeller blade 33 onto the landing pad 21 during propeller shifting has a first intersection point and a second intersection point with the inner edge line of the landing pad 21. When the first propeller-shifting component 241 is in a vertical state, its projection onto the landing pad 21 is located at the first intersection point, and when the second propeller-shifting component 242 is in a vertical state, its projection onto the landing pad 21 is located at the second intersection point.

[0060] In use, the first propeller component 241 and the second propeller component 242 rotate upwards sequentially. It should be noted that the first propeller component 241 rotates clockwise, and the second propeller component 242 rotates counterclockwise. During rotation, the first propeller component 241 contacts the propeller blade 33 and propels it into the airport unit 2 until the first propeller component 241 reaches a vertical position. The second propeller component 242 continues to propel the propeller blade 33 into the airport unit 2 until the second propeller component 242 reaches a vertical position, at which point the propeller blade 33 is propelled into the airport unit 2.

[0061] Furthermore, the airport unit 2 also includes a parking apron lifting assembly 25, used to lower the UAV 3 to the stored corresponding position after centering and propeller control, and to raise the UAV 3 to the takeoff position when it takes off. Figure 6 As shown, the helipad lifting assembly 25 includes a transmission screw structure 251; the transmission screw structure 251 is disposed at the lower part of the helipad 21. The transmission screw structure 251 includes a screw and a nut, the nut being connected to the helipad 21 to drive the helipad 21 to lift.

[0062] Furthermore, the helipad lifting assembly 25 also includes a drive chain and a drive motor 252. The output shaft of the drive motor 252 is connected to the drive chain, and the drive chain is connected to a lead screw; the drive motor 252 drives the drive chain to move, which in turn drives the lead screw to move. To prevent dust and dirt, a chain cover plate 253 is provided on the outside of the drive chain.

[0063] The usage method of this embodiment is as follows:

[0064] Step 1: Centering component 22 centers drone 3. Before drone 3 lands on landing pad 21, centering component 22 is activated; after drone 3 lands on landing pad 21, the X-axis centering component 221 drive structure is activated, and the X-axis centering rods move in opposite directions simultaneously, driving drone 3 to be centered in the X-axis direction; the Y-axis centering component 222 drive structure is activated, and the Y-axis centering rods move in opposite directions simultaneously, driving drone 3 to be centered in the Y-axis direction.

[0065] Step 2: The fixing component 23 locks the drone 3. After the drone 3 is centered, the claw hook 231 of the fixing component 23 rotates under the drive of the claw hook motor 2311 and extends out from the claw hook groove 232 to hook the foot 32 of the drone 3, thus fixing the drone 3.

[0066] Step 3: The propeller assembly 24 moves the propeller blades 33 of the UAV 3 that extend beyond the width of the airport unit 2 into the airport unit 2. The propeller drive mechanism is activated; the carbon fiber rod in the first propeller assembly 24 begins to rotate clockwise upwards. When the carbon fiber rod is vertical, part of the propeller blades 33 is moved into the airport unit 2. The carbon fiber rod in the second propeller assembly 24 begins to rotate counterclockwise upwards. When the carbon fiber rod is vertical, the remaining part of the propeller blades 33 is moved into the airport unit 2. At this point, the projection of the outermost edge of the propeller blades 33 onto the apron 21 is tangent to the inner edge of the airport unit 2.

[0067] Step 4: The helipad lifting assembly 25 lowers the drone 3 to the storage position. The drive motor 252 of the lifting assembly is activated, driving the drive chain to rotate, which in turn rotates the lead screw connected to the drive chain. The helipad 21, connected to the nut, begins to descend to the storage position.

[0068] Step 5: Close the hatch of Airport Unit 2 to ensure the safety of the internal components of Airport Unit 2 and the UAV 3.

[0069] When the drone 3 takes off, firstly, the helipad lifting assembly 25 raises the drone 3 to the takeoff position; secondly, the fixing assembly 23 unlocks the drone 3; then the drone 3 takes off.

[0070] Furthermore, six weather stations 27 are set up to monitor the surrounding environment's temperature, humidity, wind direction, wind speed, rainfall, and atmospheric pressure, ensuring the safe take-off and landing of the UAV 3 and guaranteeing the smooth progress of flight missions.

[0071] Furthermore, a 5G / WIFI antenna and a folded communication antenna are also provided, used for remote control signals of the control platform and signal transmission between UAV 3 and airport unit 2, respectively. After UAV 3 takes off, the folded antenna rises, ensuring unobstructed transmission and reception areas for the communication antenna, thus improving the transmission efficiency of both the antenna and UAV 3. When UAV 3 prepares to land on airport unit 2, the communication antenna falls down to be level with the top surface of airport unit 2, providing more landing space for UAV 3 and reducing landing risks.

[0072] Furthermore, an RTK antenna is installed for positioning of UAV 3 and airport unit 2, ensuring accurate return and landing of UAV 3; airport unit 2 is also equipped with an airport status indicator light 28 to display the working status of airport unit 2; a battery storage and charging cabinet for UAV 3 and an airport unit control cabinet are provided; an external power input port and an external network input port are provided to supply power, replenish power and provide external network access to airport unit 2; a charging box for UAV 3 is provided for replenishing the power of UAV 3; and a cooling fan is provided to prevent the battery of UAV 3 from entering the thermal protection state at high temperatures, thereby improving the battery life of UAV 3.

[0073] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
