[0003] The commonly used lifting platform generally has only one parking apron. A driving mechanism for driving the parking apron to lift is arranged below the parking apron. The unmanned aerial vehicle is taken off or landed when the parking apron is lifted to the top. Although this lifting platform is simple to operate, it can only park one unmanned aerial vehicle and cannot meet the parking demand of multiple unmanned aerial vehicles. Therefore, some people have developed a lifting platform with multiple parking aprons. However, the arrangement of multiple parking aprons is often accompanied by multiple supporting layers and related supporting expansion structures, so that the volume of the entire lifting platform is large and can only be installed on a large vehicle for use. However, the large vehicle is limited by many height restrictions in urban roads, so that the unmanned aerial vehicle intelligent airport cannot travel in some areas, affecting the flexibility and mobility of the unmanned aerial vehicle intelligent airport.

[0031] The following will be further described in detail through specific embodiments:

[0032] ​The reference numerals in the accompanying drawings include: interface component 1, plug-in component 2, first cable tray 11, interface groove 12, plug connector 21, telescopic head 22, second cable tray 23, helical spring 24, guide tube 25, upper left parking apron 311, upper right parking apron 312, rotating outer wall 41, left sliding groove 42, right sliding groove 43, ball screw fixing seat 44, ball screw helical pair, ball screw connecting plate, through groove 5, proximity switch 51, and roof plate 6.

[0033] It should be noted that the UAV vehicle-mounted lifting platform in this solution is protected in the same batch of patent applications, and this application only protects the telescopic connection structure used for the UAV vehicle-mounted lifting platform. To facilitate a clearer explanation of the telescopic connection structure, a simple structural and operational description of the UAV vehicle-mounted lifting platform is provided.

[0034] Example 1

[0035] With the widespread use of drones, intelligent drone airports have emerged. An intelligent drone airport refers to an integrated intelligent device that provides various services for drones, including takeoff, landing, recovery, and charging. To enhance the mobility and flexibility of intelligent drone airports, most current models are vehicle-mounted, allowing for free movement.

[0036] The most critical component of a drone smart airport is the lifting platform used to park the drones. The lifting platform moves to a suitable location for drone takeoff and landing via a lifting mechanism, and then is retracted into a vehicle. Commonly used lifting platforms include single-story or multi-story helipads, each corresponding to a different drone. Figure 1 and Figure 2 The existing structure is shown.

[0037] As attached Figure 1 The existing lifting platform shown has only a single-level helipad, with a single-level drive mechanism underneath to raise and lower the helipad. When the single-level drive mechanism raises the helipad to its highest point, it reaches the take-off and landing position for the drone, which is typically an unobstructed location. This type of lifting platform can only park drones on a single level, limiting the number of drones that can be parked simultaneously, making it unsuitable for parking multiple drones at the same time.

[0038] As attached Figure 2 The existing lifting platform shown no longer uses a single-level helipad in order to accommodate more drones at the same time. Figure 2The lifting platform shown includes a first-level helipad and a second-level helipad, positioned vertically. To ensure unobstructed takeoff and landing of drones on both helipads, support plates are installed below the first and second helipads, allowing them to slide horizontally left and right. Because the first and second helipads need to be completely offset horizontally and not obstructed by the two support plates, allowing drones on the second helipad to take off and land unobstructed, the horizontal length of the entire lifting platform is very long. Combined with the structure of the two helipads and support plates, the vertical length of the entire lifting platform is also very long, resulting in a large overall size and footprint. This means it can only be installed on large vehicles with ample internal space. However, the movement of these large vehicles in urban areas is restricted; they cannot enter many height-restricted areas, directly impacting the drivable area of ​​the drone airport and affecting its mobility and flexibility.

[0039] In view of this, we have developed a small-sized automatic lifting platform for double-layer helipads that does not take up much space when the two layers of helipads are deployed.

[0040] like Figure 7 As shown, the drone vehicle-mounted lifting platform in this solution is a double-layer automatic lifting platform with two symmetrically arranged rotating outer walls 41. Two upper and lower landing pads are slidably connected between the two rotating outer walls 41. Each landing pad includes two landing pads on the left and right sides. Each of the two landing pads on one layer can accommodate a small drone, or a large drone can be accommodated together on both landing pads on the same layer. Figure 7The upper left and upper right helipads 311 and 312 on the upper level can be used to park a small drone individually, or they can be combined to accommodate a large drone, allowing for flexible use based on user needs. The inner side of the rotating outer wall 41 is equipped with sliding rails for each helipad to move. Each rail is roughly rectangular with rounded corners, allowing the two helipads to rotate and move according to their shape. Because each helipad on both levels can rotate with the rails, and the two helipads on the same level move sequentially rather than side-by-side at the same height, the area at any given height is limited to the size of one helipad. This avoids the need for the two helipads to be completely flat, effectively shortening the overall length of the double-layer helipad. The lateral distance of the automatic lifting platform for the helipad is also reduced because the slide rail in this solution is installed on the inner side of the rotating outer wall 41, and the height of the rotating outer wall 41 is almost the height between the two helipads. This effectively reduces the vertical length of the entire double-layer automatic lifting platform, making the entire double-layer automatic lifting platform smaller in both its own size and the space it occupies during use. It can even be installed and used in ordinary small and medium-sized vehicles, increasing its applicability and thus increasing the area that the UAV intelligent airport can operate in, thereby increasing the mobility and flexibility of the UAV intelligent airport.

[0041] like Figure 7 As shown, the drone vehicle-mounted lifting platform has a vertically arranged ball screw mounting base 44 installed on the outer side of each rotating outer wall 41. A vertically arranged left sliding groove 42 and a right sliding groove 43 are symmetrically installed on both sides of the ball screw mounting base 44. The arrangement of the ball screw mounting base 44, the left sliding groove 42, and the right sliding groove 43 provides the lifting power for the entire drone vehicle-mounted lifting platform to move up and down.

[0042] The slide rail between the two rotating outer walls 41 is specifically a wheel mechanism, which connects to the upper and lower helipads. There are two sets of wheel mechanisms, including a left wheel mechanism and a right wheel mechanism arranged opposite each other; each wheel mechanism has an outer wheel track, an inner wheel track, and a straight track. The outer wheel track is a square track, and the straight track is a vertical straight track that communicates with both the upper and lower track sections of the outer and inner wheel tracks; the wheel mechanism contains a drive control mechanism for rotating the outer wheel track. The inner wheel track consists of a first inner track located below the upper track section of the outer wheel track, and a second inner track located above the lower track section of the outer wheel track. The inner wheel track communicates with the outer wheel track.

[0043] Each helipad has bearing assemblies at both ends of its bottom. Each bearing assembly includes an upper bearing pair and a lower bearing pair; each bearing pair consists of two bearings spaced a predetermined distance apart. The upper and lower bearing pairs are also spaced a certain distance apart. The bearing assemblies at both ends are connected to the wheel track on the left and right wheel mechanisms, respectively; when the wheel tracks rotate, they move the bearing assemblies together.

[0044] A lifting mechanism, consisting of a ball screw and other components, is used to drive a rotating mechanism to move up and down. The rotating mechanism has a connecting part that connects to the transmission part of the ball screw, thereby driving the ball screw to move the rotating mechanism up or down.

[0045] In this solution, the two-layer helipad moves in a staggered vertical motion, which can effectively save space occupied when the helipad changes position vertically. This is conducive to the large-capacity miniaturization of the entire mobile airport. This solution can simultaneously accommodate one large UAV and two small UAVs or four small UAVs.

[0046] like Figure 3 and Figure 5 As shown, the drone's vehicle-mounted lifting platform can be viewed by opening the roof panel. Figure 4 and Figure 6 As shown, open the rear door to view the drone's vehicle-mounted lifting platform from the rear door.

[0047] The UAV vehicle-mounted lifting platform in this solution is a double-layer automatic helipad platform installed inside the vehicle of the UAV smart airport. The top of the vehicle has a retractable door for UAVs to enter and exit. The UAV vehicle-mounted lifting platform can switch between upper and lower helipads in a relatively small vehicle, which facilitates the take-off and landing control of multiple UAVs. The UAV vehicle-mounted lifting platform in this solution has the characteristics of easy operation, small size and large capacity, and high efficiency.

[0048] In this embodiment, the telescopic connection mechanism for the UAV vehicle-mounted lifting platform is used to connect with the UAV vehicle-mounted lifting platform when it moves to the top floor helipad. This allows the two helipads at the top floor to communicate with other cables and equipment of the entire smart airport through the telescopic connection mechanism. By setting up the telescopic connection mechanism, the helipads can quickly connect with other structures and control systems of the mobile airport when they rotate to the top floor position.

[0049] like Figure 8 and Figure 9 As shown, a telescopic connection mechanism for a vehicle-mounted lifting platform for unmanned aerial vehicles includes a paired interface component 1 and a plug component 2; the plug component 2 can be inserted into the interface component 1 to conduct the connection circuit between the plug component 2 and the interface component 1.

[0050] like Figure 7As shown, the interface component 1 is welded onto each landing pad of the UAV vehicle-mounted platform; the plug-in component 2 is installed at the top of the rotating outer wall 41 near the interface component 1. Both the interface component 1 and the plug-in component 2 have rectangular shells, and the width of the plug-in component 2's shell is greater than the width of the interface component 1's shell. By installing the interface component 1 and the plug-in component 2 near each other on the landing pad and the rotating outer wall 41, the plug-in component 2 only needs to cross the distance between the landing pad and the rotating outer wall 41 when it extends near the interface component 1, which facilitates alignment and has a short extension distance. The shell width of the plug-in component 2 is greater than the shell width of the interface component 1, which facilitates the installation of a proximity switch 51 inside the shell of the plug-in component 2 to detect whether the landing pad is parked on the top layer of the UAV vehicle-mounted lifting platform. When proximity switch 51 detects that the corresponding landing pad is positioned at the top layer of the UAV vehicle-mounted lifting platform, i.e., when the outer shell of interface component 1 and the outer shell of connector 2 are facing each other, and when the connector 21 on telescopic head 22 corresponds to the corresponding charging port or data connection port in interface slot 12, it facilitates connector 2 to approach interface component 1 and insert connector 21 into the corresponding charging port or data connection port. In this embodiment, there is only one type of connector 21, and there is also only one corresponding charging port or data connection port at the bottom of interface slot 12. Of course, multiple different connectors 21 can be installed on one telescopic head 22, with different charging ports or data connection ports installed at the bottom of interface slot 12.

[0051] like Figure 8 and 9 As shown, the interface component 1 includes an interface slot 12 with one open end and a first cable conduit 11 for routing wires through the interface slot 12. The bottom of the interface slot 12 is provided with a charging port and / or a data connection port. The charging port or data connection port at the bottom of the interface slot 12 uses commercially available components. After connecting to these components with wires, the wires are routed through the first cable conduit 11 to connect to various functional module circuits installed in the helipad. Each functional module circuit can be configured according to the user's actual needs, such as a weighing module circuit, a temperature module circuit, a Bluetooth module circuit, or other commonly used functional module circuits. The installation of the module circuits is not a matter to be protected in this solution and will not be described further here.

[0052] The connector 2 is used to dock with the interface component 1, which rotates to the top of the drone's lifting platform. The connector 2 includes a telescopic head 22 that matches the inner contour shape of the interface slot 12. In this embodiment, the telescopic head 22 is an elliptical cylinder with an elliptical cross-section and a smooth outer surface. This helps the telescopic head 22 to enter the interface slot 12, which matches the outer contour shape, with as little obstruction as possible, effectively reducing the docking time between the connector 2 and the interface component 1.

[0053] The telescopic head 22 has a connector 21 for electrical connection to the charging port and / or data connection port at one end near the interface slot 12, and a second cable tray 23 for routing the connector 21 at the other end away from the interface slot 12. The connector 21 is a commonly used connector. The wires connected to the connector 21 pass through the telescopic head 22, through the second cable tray 23, and then through the cable channel 5 to connect to other electronic devices installed on the UAV vehicle-mounted lifting platform and other electronic devices and circuits in the entire UAV smart airport.

[0054] A helical spring 24 is sleeved around the second cable tube 23. One end of the helical spring 24 is connected to the telescopic head 22, and the other end is connected to the outer wall of the connector 2. During the extension or retraction of the telescopic head 22, the helical spring 24 acts as a buffer to stabilize the telescopic head 22. The second cable tube 23 is located at the center of the telescopic head 22, and the helical spring 24 surrounds the second cable tube 23, so that the helical spring 24 provides a relatively balanced buffering force to the telescopic head 22 in the lateral direction as much as possible during the lateral movement of the telescopic head 22.

[0055] The end of the telescopic head 22 furthest from the interface slot 12 is connected to four guide tubes 25, symmetrically arranged on both sides of the helical spring 24. A miniature electric push rod is installed inside each guide tube 25 to push the telescopic head 22 and the connector 21 closer to or further away from the interface slot 12. This arrangement makes the telescopic head 22 extend and retract more smoothly, allowing it to be inserted into the interface slot 12 more quickly and accurately. The end of the miniature electric push rod is fixed to the outer wall of the interface component 1; any miniature electric push rod of the corresponding size and extension length can be sourced from the market.

[0056] In this embodiment, the interface component 1 is located at the midpoint of the side length of the single landing pad near the outer wall 41 of the rotary gate. Both the interface component 1 and the connector 2 have rectangular shells. The width of the shell of the interface component 1 is one-tenth to one-fifth of the side length of the landing pad, and the width of the shell of the connector 2 is greater than the width of the shell of the interface component 1. This design facilitates the installation of the connector 2 and the interface component 1, allows for quick alignment and connection of the connector 2 and the interface component 1, and does not excessively occupy or affect the volume and usable space of the UAV vehicle-mounted lifting platform.

[0057] In this embodiment, both the first wire bundle 11 and the second wire bundle 23 are rectangular tubular structures, but flat tubular structures can also be used for easy connection. A heat dissipation coating can also be applied to the outer walls of the first wire bundle 11 and the second wire bundle 23 to improve heat dissipation efficiency.

[0058] This embodiment can be used in conjunction with a new type of UAV vehicle-mounted lifting platform. Under limited structural settings, it can complete charging and / or information transmission for the landing pad in the UAV vehicle-mounted lifting platform. This makes the UAV landing pad not only limited to simple parking functions, but also provides the premise and foundation for installing more functional module circuits on the landing pad, making future UAV vehicle-mounted lifting platforms more intelligent.

[0059] The interface component 1 and the plug-in component 2 have a simple structure but a clever design that allows for quick plug-in operations. Furthermore, both the proximity switch 51 and the miniature electric push rod are made of readily available, smaller electronic components. In addition, the clever design of the installation positions of the interface component 1 and the plug-in component 2 does not increase the volume or usable space of the drone vehicle-mounted lifting platform, but it can utilize the time spent parking on the top floor to complete charging and / or information transmission operations.

[0060] Example 2

[0061] like Figure 10 As shown, unlike Embodiment 1, in this embodiment, the connector 2 is installed on the roof panel 6, and the interface slot 12 in the interface component 1 opens upwards. Neither connector 2 nor interface component 1 has a shell, further reducing the volume occupied. The guide tube 25 in connector 2 is directly installed below the roof panel 6. The guide tube 25 does not need to be installed with a micro electric push rod; it only serves as a guide and connection. When the interface component 1 rises to the roof with the UAV vehicle-mounted lifting platform, connector 2 is inserted into interface component 1. After the connection is completed, interface component 1 descends with the UAV vehicle-mounted lifting platform, connector 2 and interface component 1 separate, the roof panel 6 is flipped open to reveal the roof exit, and the UAV vehicle-mounted lifting platform raises the top helipad to be flush with the roof.

[0062] The rotating outer wall 41 of the drone vehicle-mounted lifting platform is equipped with a proximity switch 51 to detect whether the landing pad has reached the top layer of the lifting platform.

[0063] Of course, a miniature electric push rod can also be installed in the guide tube 25. The end of the miniature electric push rod is directly fixed to the roof panel 6, so that when the interface piece 1 rises with the lifting platform, the plug-in piece 2 can also be pushed downward by the miniature electric push rod.

[0064] In this embodiment, by installing the connector 2 onto the roof panel 6, the wiring of the connector 2 can be routed along the roof panel 6, making wiring and connection with other electronic devices and circuits of the drone smart airport more convenient. Moreover, by utilizing the lifting power of the lifting platform itself, the power required for the connector 2 to extend near the interface piece 1 can be reduced or eliminated, resulting in greater energy savings.

[0065] Example 3

[0066] Unlike Embodiment 1, in this embodiment, the telescopic head 22 has an elliptical cross-section, with the cross-sectional area at the end near the interface groove 12 being smaller than that at the end away from the interface groove 12. In other words, the telescopic head 22 is a cone-shaped structure that gradually increases in size from the end near the interface groove 12 to the end away from the interface groove 12, and the inner contour of the interface groove 12 is correspondingly changed. This design reduces resistance and makes insertion of the telescopic head 22 into the interface groove 12 smoother.

[0067] Example 4

[0068] Unlike Embodiment 1, the guide tube 25 has an elastic corrugated structure, and the electric actuators are housed within the helical spring 24. The center point of the four electric actuator force application points is the center point of the force-bearing surface of the telescopic head 22, making the extension and retraction of the connector 2 more stable.

[0069] Example 5

[0070] In this embodiment, the telescopic stroke distance of the miniature electric actuator is greater than or equal to 1.5-2 times the distance between the helipad and the adjacent rotating outer wall 41, so that the miniature electric actuator can push the connector 21 to connect with the charging port or data connection port and support it to complete charging or information transmission.

[0071] Example 6

[0072] In this embodiment, the telescopic head 22 has various types of connectors 21, including charging connectors for charging and communication connectors for communication transmission. The distribution center formed by the center lines connecting the centers of all charging connectors and communication connectors coincides with the center of the end face of the telescopic head 22 near the interface slot 12. Thus, regardless of the number of connectors 21 on a single telescopic head 22, the force on the telescopic head 22 remains balanced. Of course, in this embodiment, the number of connectors 21 on a single telescopic head 22 is generally limited to no more than three. This ensures that as many connections as possible are completed within a limited volume, and that normal operation is not affected by overheating or other factors.

[0073] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
