Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to a portable, foldable dock-type UAV take-off and landing platform. Background Technology

[0002] With the increasing popularity of drone applications, drone operation scenarios are becoming more and more diverse. When rotary-wing drones take off and land with a load, there are usually the following situations: (1) When the load height is above the drone landing gear, if the load is not large, it can be fixed to the drone. Rotary-wing drones only need a certain area of ​​horizontal space for take-off and landing; (2) When the load height is below the drone landing gear, the drone needs to be equipped with a sling and hook to hang the load. Usually, the drone takes off, hooks the load with the hook, and then takes off. The same applies when landing. The load needs to be placed in a designated position first and then the hook needs to be released before the drone lands. When the sling is long enough, people can usually help to hook the load. However, when the sling is short, it is necessary to control the drone and hook to hook the load, which requires high operation skills and is inefficient. For the second situation where the load height is below the drone landing gear and the sling cannot be too long, a take-off and landing method and platform that can improve both site applicability and take-off and landing efficiency is needed.

[0003] Chinese patent document CN206706593U discloses a foldable drone take-off and landing platform, including a take-off and landing platform that can be folded downwards along its center of symmetry and support leg assemblies located below the four corners of the platform. Each support leg assembly is hinged to the platform via a hinge connector. Each support leg assembly includes an outer support leg and an inner support leg. The outer support leg has a downward-opening channel along a vertical direction inside, and the inner support leg is slidably positioned within the channel along the vertical direction of the outer support leg. The outer and inner support legs are locked in place by a positioning component. This design allows the drone to take off from any location on the construction site, regardless of terrain conditions, saving time, improving efficiency, facilitating drone supervision and management on construction sites, and making it easy to store and carry.

[0004] While the aforementioned patented solution allows for easy portability of the take-off and landing platform through folding, it doesn't provide a simple take-off and landing experience for drones carrying loads, as the platform lacks a designated area to accommodate the load. Even with gaps in the platform to accommodate the load, the supporting structure is compromised, reducing the platform's stability. The platform's swaying during take-off and landing poses a potential safety hazard to both the drone and its load. Utility Model Content

[0005] To overcome the technical problems of existing take-off and landing platforms being unusable by drones carrying loads, and the support structure of the platform still occupying a large space after folding, making it inconvenient to carry and use, this utility model aims to provide a portable, foldable dock-type drone take-off and landing platform. By setting up a multi-stage folding base and side frames, and a removable top frame between the two side frames, the folded volume is reduced while ensuring the support strength after assembly. Two foldable platform plates with spaced gaps are set on the upper part of the two side frames, providing space for the drone's under-mounted load, thus improving the convenience of take-off and landing.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a portable, foldable dock-type drone take-off and landing platform, comprising a base frame, two side frames respectively disposed on the upper end of the base frame, a top frame detachably connected to the upper end of the two side frames, and two platform plates respectively rotatably connected to the upper end of the two side frames; a gap for accommodating load is provided between the two platform plates; wherein, the top frame includes two crossbars rotatably connected at their ends and two adapters respectively disposed at the other end of the two crossbars; the adapters are provided with limiting grooves for insertion into adjacent side frames; at least one pin is slidably connected to the adapter, and the pin can be selectively inserted into the corresponding side frame.

[0007] The drone's landing gear takes off and lands on the platform, and the drone's under-mounted load is located in the gap, which facilitates the drone's takeoff and landing.

[0008] Furthermore, two right-angle positioning parts are provided between the base frame and the side frame; the right-angle positioning part includes a long plate provided on the base frame, a short plate provided on the side frame, a support rod rotatably connected at one end to the short plate, and a limiting buckle rotatably connected on the long plate for engaging with the other end of the support rod; the end of the long plate near the adjacent side frame is rotatably connected to the end of the short plate near the base frame.

[0009] Specifically, the long plate is provided with a sliding groove along its length that is slidably connected to the support rod; the middle part of the limiting buckle is rotatably connected to the upper part of the sliding groove; the center of gravity of the limiting buckle is located on the side of its rotation axis close to the short plate; the end of the limiting buckle can be selectively rotated to the top or bottom of the sliding groove.

[0010] During the sliding of the support rod along the slide groove, the support rod enables the limiting buckle to rotate. When the long plate is perpendicular to the short plate, the limiting buckle rotates under the action of gravity with an eccentric setting, blocking the support rod from sliding along the slide groove, thereby fixing the long plate and the short plate relatively, that is, fixing the side frame and the base frame relatively.

[0011] Preferably, the cross-sections of the long plate and the short plate are U-shaped; the short plate is located inside the opening of the long plate, and the opening of the short plate is directly opposite the opening of the long plate; there are two support rods, which are respectively arranged on both sides of the long plate; a connecting shaft that is rotatably connected to the short plate is provided between the two support rods; and an opening groove for accommodating the connecting shaft is provided on the long plate.

[0012] When folded for storage, the short board enters the long board, and the connecting shaft enters the opening slot, reducing the folded volume.

[0013] Furthermore, the base frame includes two half-frames whose ends are rotatably connected to each other; the side frame is disposed at the other end of the half-frame; the rotation axis of the half-frame is located at the lower end of the base frame.

[0014] Furthermore, the side frame includes three rectangular frames whose ends are rotatably connected in sequence; the two rotation axes of the side frame are respectively disposed on both sides of the rectangular frames.

[0015] Specifically, linear positioning parts for locking positions are respectively provided between the two half-frames, between the two adjacent rectangular frames, and between the two crossbars; the linear positioning part includes a slide rod and two hand-tightening screws respectively threaded to both ends of the slide rod; the half-frames, the rectangular frames, and the crossbars are respectively provided with T-slots that are slidably connected to the slide rods.

[0016] Specifically, the adapter is provided with two pins; the two pins are respectively inserted into two adjacent sides of the rectangular frame.

[0017] The base frame, side frame, and top frame can all be folded in multiple stages, which helps to reduce the volume after folding.

[0018] Preferably, the platform is rotatably connected to the side of the side frame away from the base frame; the side of the platform away from the crossbar is provided with a chamfer within the gap.

[0019] Preferably, the lower end of the side frame is threaded with two support legs; the base frame is located above the support legs.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model adopts a foldable frame design made of aluminum alloy profile, which makes the take-off and landing platform lightweight, flexible and convenient to disassemble and carry. The take-off and landing platform can also be adjusted for level by the support legs, which also reduces the site requirements for drone take-off and landing.

[0022] 2. This utility model, through the design of a dock-type frame structure, not only solves the safety problem of take-off and landing with a load (load height lower than the drone landing gear), but also saves site space and improves the operational efficiency of drone operations.

[0023] 3. This utility model, through its embedded linear positioning part design and interlocking right-angle positioning part setting, not only provides a more stable support effect for the folding frame and ensures the safety of drone take-off and landing, but also ensures that the folded size is small and easy to carry by hand.

[0024] 4. This utility model has a simple, compact structure, and is mostly assembled and manufactured using common parts, resulting in low overall cost and thus reducing usage costs. Attached Figure Description

[0045] Usage: During takeoff, the drone, equipped with a lanyard and hook, is first placed on the unfolded and adjusted takeoff and landing platform. The hook can carry various loads. The drone, loaded with its cargo, takes off to a certain height. The drone's landing gear detaches from the platform 5, ensuring the load below does not touch the platform 5. If it does touch the platform 5, it can rotate freely upwards; being lifted will not affect flight safety. Alternatively, it can be moved horizontally out of the overall frame along the opening of the slot 8. Then, the drone can be pulled up for flight.

[0046] The landing process is the exact opposite of the takeoff process; the drone first lands on the floor specified in the manual. Figure 7 At the specified height, align the drone's lanyard with the gap 8, move it horizontally to the middle, and simultaneously align the drone's tripod with the platform 5, then descend onto the platform 5.

[0047] Folding and storage process: Fold the platform 5 open to both sides so that it hangs down naturally, pull out all the pins 43, and remove the top frame 4 from the two side frames 2. Loosen the hand screws 32 on the top frame, slide the slide rod 31 onto one of the crossbars 41, fold the two crossbars 41 in half, and tighten a hand screw here to fix the slide rod 31 relative to the crossbar 41. Similarly, loosen all the hand screws 32 and slide the slide rod 31 onto one of the rectangular frames 21 or half-frames 11. Then, rotate the limit buckle 64 on the base frame 1 so that it no longer abuts against the support rod 63, as shown. Figure 6 As shown, the entire frame is folded.

[0048] Unfolding process: such as Figure 6 As shown, pull the whole assembly apart, place the two half-frames 11 horizontally, slide the corresponding slide rods 31 to the middle of the two half-frames 11, and tighten the hand screws 32. Rotate the bottom rectangular frame 21 to vertical, and slide the support rod 63 along the slide groove 611 until it abuts against the lower end of the limit buckle 64 and is limited. Then adjust each rectangular frame 21 to vertical in sequence and lock it through the linear positioning part 3.

[0049] Finally, unfold the crossbar 41 and lock it with the linear positioning part 3. Align the two side frames 2 with the limiting grooves 421 and insert them. Insert the pins 43 into the corresponding T-slots. Flip the platform 5 to the top of the side frames 2 to complete the assembly.

[0050] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
