Description

Technical Field

[0001] This utility model relates to the technical field of drone assisted take-off and landing equipment, specifically to a lightweight and foldable drone take-off and landing platform. Background Technology

[0002] With the popularization of drone technology, its application in field operations such as forestry inspection, power surveying, and disaster relief is becoming increasingly widespread. The safe takeoff and landing of drones places clear demands on the flatness and stability of the operating site: uneven surfaces can easily cause drones to tip over during takeoff, become unbalanced during landing, or cause damage to the propellers from collisions with ground obstacles. To ensure stable takeoff, a drone takeoff platform needs to be designed. However, traditional takeoff platforms cannot be folded and stored, occupying a large space and being inconvenient to carry and use. Therefore, foldable drone takeoff platforms have been designed, for example: 1. Chinese Patent: Foldable UAV Takeoff Platform for Multi-Environment Applications, Application No.: 201820616332.6, Application Date: April 26, 2018, Abstract: This utility model discloses a foldable UAV takeoff platform for multi-environment applications, including a foldable platform plate and multiple retractable foldable telescopic rod assemblies; wherein, the multiple retractable foldable telescopic rod assemblies are evenly arranged at the bottom of the foldable platform plate, and the retractable foldable telescopic rod assemblies and the foldable platform plate are freely rotatable and engaged through a rotating shaft; the center position of the foldable platform plate is an unextended panel, and multiple extension fold lines are provided on the foldable platform plate and along the periphery of the unextended panel; the foldable platform plate is used to achieve folding by following the extension fold lines; the unextended panel located at the center of the foldable platform plate is also provided with marking lines to facilitate UAV takeoff and landing identification. The foldable UAV takeoff platform for multi-environment applications provided by this utility model has the technical advantages of strong environmental adaptability, height adjustment, and expandability and foldability.

[0003] 2. Chinese Patent: A Portable Drone Take-off and Landing Platform with Adjustable Four-Legged Landing Surface and Foldable Design, Application No.: 201711092793.4, Application Date: 2017.11.08, Abstract: This invention relates to a portable drone take-off and landing platform with an adjustable four-legged landing surface and foldable design, particularly suitable for use in power transmission line inspections by drones, belonging to the technical field of power transmission line maintenance equipment. It includes a foldable landing surface, a foldable and height-adjustable support mechanism installed below the landing surface, and a drone mounting mechanism, a drone fixing mechanism, and a leveling mechanism on the landing surface for mounting the drone. This invention has a simple structure, is easy to carry, low in cost, has adjustable four legs, and a foldable landing surface, making it suitable for use in mountainous areas, farmland, grasslands, and other terrains with overgrown weeds and uneven surfaces.

[0004] Application research revealed that while the aforementioned takeoff platform solved the problems of folding and storage and adaptability to basic terrain for UAV takeoff platforms, it still has significant technical limitations: First, no reinforced structure was designed for the load-bearing stability of the folding platform plate. If the platform plate is made of flexible materials such as canvas, it is prone to collapse in the middle under the pressure of the UAV or the action of wind, which cannot guarantee the flatness of the takeoff plane or meet the stable support requirements during landing. Second, the retractable folding telescopic rod assembly only relies on the conical bottom to adapt to muddy ground. In rocky or hardened ground environments where the conical structure cannot be inserted, there is a lack of suitable fixing structure, which can easily lead to slippage and displacement, and insufficient fixing reliability. It is difficult to meet the high requirements for platform stability and multi-terrain adaptability in scenarios such as field surveying, geological exploration, and emergency rescue. Summary of the Invention

[0005] The purpose of this invention is to address the core pain points of existing drone take-off and landing platforms, such as the easy collapse of flexible platform panels, the limited terrain adaptability of support structures, and the insufficient portability of foldable platforms, and to provide a drone take-off and landing platform that is simple in structure, lightweight, foldable, and adaptable to multiple terrains.

[0006] This utility model is achieved using the following technical solution: A lightweight, foldable drone take-off and landing platform includes a foldable canvas platform. Each of the four corners of the foldable canvas platform has an upper connecting seat fixedly mounted on its bottom. A scissor brace is hinged between each two adjacent upper connecting seats. The scissor brace is a foldable aluminum frame made of high-strength, lightweight aluminum alloy, giving the foldable canvas platform a foldable, cross-shaped support structure. When folded, its volume is significantly reduced, allowing it to be packed into a storage bag. The tops of the two support rods of the scissor brace are hinged to the two adjacent upper connecting seats. The bottom ends of the two adjacent scissor braces are hinged to a lower connecting seat. The lower connecting seat has vertically arranged ground spike holes, into which ground spikes are inserted. Bolt holes communicating with the ground spike holes are provided on the side of the lower connecting seat, and locking bolts are installed in the bolt holes to lock and fix the ground spike holes. The ground spikes can be inserted into the ground to secure the platform. Adjusting the locking bolts changes the height of the ground spike support, providing a basis for horizontal alignment. The bottom of the folding canvas platform is fixed with cross-shaped steel cables. Each of the four corners of these cables is connected to one of the four corners of the platform's bottom. This means two high-strength galvanized steel cables are diagonally connected at the bottom of the platform, directly supporting the central area of ​​the canvas. This transforms the single-point load-bearing capacity of the canvas into full-area tensile support, ensuring the platform's surface flatness and preventing the flexible platform from collapsing. The folding canvas platform is made of high-strength, wear-resistant Oxford cloth, possessing sufficient load-bearing capacity to withstand the impact of drone takeoff and landing. Its dimensions perfectly match the aluminum folding frame.

[0007] A further preferred embodiment: a tension rope connects the upper connecting seat and the corresponding lower connecting seat. The tension rope is made of high-strength, wear-resistant polyester rope. After the folded canvas platform is unfolded, the tension rope is used to tautly connect the upper connecting seat and the corresponding lower connecting seat.

[0008] A further preferred embodiment includes a counterweight mechanism connected to the ground stake. When used on rocky or hardened surfaces where anchors cannot be inserted, the platform is secured by placing a weight on the counterweight mechanism, utilizing gravity and friction, thus adapting to various types of outdoor terrain.

[0009] A further preferred embodiment: The counterweight mechanism includes a counterweight plate and a connecting sleeve. The counterweight plate is fixedly connected to the connecting sleeve, which is fitted onto the ground nail. A fixing bolt is installed on the side of the connecting sleeve for locking with the ground nail hole. The connecting sleeve can be fixed in position on the ground nail by tightening or loosening the fixing bolt. After adjusting it to the appropriate position, the fixing bolt is tightened, and then the counterweight is placed on the counterweight plate.

[0010] This lightweight, foldable drone takeoff and landing platform has the following advantages: 1. Dual protection against collapse and stability: In the combined tension system, the tension support formed by the cross-shaped steel wire ropes directly supports the middle of the canvas. Compared with the traditional unsupported canvas platform, the flatness is improved by more than 90%, avoiding collisions when the drone takes off and lands; the four-sided tension ropes improve the deformation resistance of the frame by more than 60%, making the overall structure more stable.

[0011] 2. Multi-terrain adaptability: Through the matching design of ground stakes and counterweight devices, it is adaptable to more than 90% of the core operating terrain in the field, and the switching operation does not require tools, making it highly convenient for field use.

[0012] 3. Lightweight and portable: The combination of aluminum frame and canvas material results in an overall weight of ≤2.0kg. When folded, the volume is only 1 / 4 of the unfolded state. Folding and unfolding operations are convenient and quick, meeting the needs of rapid deployment in field operations. Attached Figure Description

[0014] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments. The described embodiments are only a part of this utility model, and not all of them.

[0015] Example 1

[0016] A lightweight, foldable drone take-off and landing platform includes a foldable canvas platform 8. Each of the four corners of the foldable canvas platform 8 has an upper connecting seat 7 fixedly installed at its bottom. A scissor brace 6 is hinged between each two adjacent upper connecting seats 7. The scissor brace 6 is an aluminum folding frame made of high-strength, lightweight aluminum alloy, giving the foldable canvas platform 8 a foldable, cross-shaped support structure. After folding, its volume is significantly reduced, allowing it to be packed into a storage bag. The tops of the two support rods of the scissor brace 6 are hinged to the two adjacent upper connecting seats 7, and the bottom ends of the two adjacent scissor braces 6 are hinged to a lower connecting seat 3. The lower connecting seat 3 has vertically arranged ground nail holes 4, with ground nails 1 inserted into the ground nail holes 4. Bolt holes communicating with the ground nail holes 4 are provided on the side of the lower connecting seat 3, with locking bolts 2 installed in the bolt holes to lock and fix the ground nail holes 4. The ground nails 1 can be inserted into the muddy ground to fix the platform. Adjusting the locking bolts 2 can change the support height of the ground nails 1, providing a basis for horizontal calibration. The bottom of the folding canvas platform 8 is fixed with cross-shaped steel wire ropes 9. The four corners of these cross-shaped steel wire ropes 9 are fixedly connected to the four corners of the bottom of the folding canvas platform 8. This means that two high-strength galvanized steel wire ropes are diagonally connected to the bottom of the folding canvas platform 8, directly supporting the central area of ​​the canvas. This transforms the single-point load-bearing of the canvas into full-area tensile support, ensuring the flatness of the platform surface and solving the problem of flexible platform panel collapse. The folding canvas platform 8 is made of high-strength, wear-resistant Oxford cloth, possessing sufficient load-bearing capacity to withstand the impact of drone takeoff and landing, and its dimensions perfectly match the aluminum folding frame.

[0017] A tension rope 5 connects the upper connecting seat 7 to the corresponding lower connecting seat 3. The tension rope 5 is made of high-strength, wear-resistant polyester rope. After the folding canvas platform 8 is unfolded, the tension rope 5 is used to tautly connect the upper connecting seat 7 and the corresponding lower connecting seat 3.

[0018] The ground stake 1 is connected to a counterweight mechanism. When used on rocky or hardened surfaces where anchors cannot be inserted, a weight is placed on the counterweight mechanism, and the platform is fixed by gravity and friction, making it suitable for various types of outdoor terrain.

[0019] The counterweight mechanism includes a counterweight plate 10 and a connecting sleeve 12. The counterweight plate 10 is fixedly connected to the connecting sleeve 12, which is fitted onto the ground nail 1. A fixing bolt 11 for locking the connecting sleeve 12 with the ground nail hole 4 is installed on the side of the connecting sleeve 12. The connecting sleeve 12 can be fixed in position on the ground nail 1 by tightening or loosening the fixing bolt 11. After adjusting it to a suitable position, the fixing bolt 11 is tightened, and then the counterweight is placed on the counterweight plate 10.

[0020] The operating steps for using this lightweight, foldable drone take-off and landing platform are as follows: Step 1: Take out the folded integrated main unit, unfold the aluminum folding frame to the fully extended state, and unfold the folding canvas platform synchronously with the frame to ensure that the frame is not loose and the folding canvas platform is fully unfolded. Step 2: Check the cross-shaped steel wire ropes at the bottom of the canvas platform. If they are loose, tighten the fixing bolts on the four corner connectors of the frame by hand to make the steel wire ropes taut to form a complete tensile support net and ensure that the canvas surface is flat. Step 3: Connect the four tension ropes to the upper and lower connecting seats respectively; tighten the tension ropes, and check the overall stability of the frame after all four tension ropes are tied. Step 4: Insert ground nails into the ground nail holes of the four lower connectors respectively; Step 5: Choose the fixing method according to the terrain: For muddy ground, directly insert the ground nail vertically into the ground until it is stable; for rock or hardened ground, install a counterweight device at the bottom of the ground nail, that is, insert the connecting sleeve and tighten the fixing bolt, and then place a weight on the counterweight plate to strengthen the fixation. Step 6: Adjust the fixing position of the lower connecting seat and the ground nail by tightening the locking bolts to ensure that the folding canvas platform is level; Step 7: After the drone takes off and lands, remove the weights (if used) and counterweights, remove the ground spikes, loosen the tension ropes, fold the frame to its storage position, and put it into the storage bag.
