Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) auxiliary equipment technology, specifically to a device for safe take-off and landing of UAVs in complex terrain. Background Technology

[0002] With the development of drone technology, its application scenarios have expanded to complex terrain environments such as outdoor exploration, mountain rescue, and agricultural plant protection.

[0003] However, existing UAV take-off and landing platforms have poor support structure adaptability during use, mostly consisting of fixed legs or single-degree-of-freedom folding legs, which cannot adapt to uneven or steep terrain, easily causing the take-off and landing panel to tilt. Furthermore, they lack anti-sinking design, making them prone to sinking on soft ground, affecting stability. At the same time, their wind resistance is insufficient, and crosswinds can easily cause UAVs to deviate during take-off and landing, or even collide and be damaged. Leveling depends on manual operation, which is inefficient and has poor accuracy. Therefore, we propose a safe take-off and landing platform device for UAVs in complex terrain. Utility Model Content

[0004] In view of the problems existing in the above-mentioned safe take-off and landing platform devices for UAVs in complex terrain, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a safe take-off and landing platform device for UAVs in complex terrain. It solves the problems of existing UAV take-off and landing platforms, which have poor adaptability of support structure, mostly fixed legs or single-degree-of-freedom folding legs, which cannot adapt to uneven or steep terrain, easily causing the take-off and landing panel to tilt. In addition, they lack anti-sinking design, are prone to sinking on soft ground, affecting stability. At the same time, they have insufficient wind resistance, and crosswinds can easily cause UAVs to deviate during take-off and landing, or even collide and be damaged. Leveling depends on manual operation, which is inefficient and has poor accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A safe take-off and landing platform device for unmanned aerial vehicles (UAVs) in complex terrain includes a take-off and landing panel, fixed sleeves, and anti-sinking pads. The bottom of the take-off and landing panel has multiple telescopic inner rods, each with a fixed sleeve slidably mounted on its surface. Pressure sensors are fixedly installed on the tops of each fixed sleeve, and anti-sinking pads are fixedly installed on the bottoms of each pressure sensor. First wind deflectors are hinged to both sides of the take-off and landing panel, and second wind deflectors are hinged to both ends of the take-off and landing panel. Multiple locking blocks are fixedly installed at both ends of the two first wind deflectors, and multiple slots are provided on both sides of the surfaces of the two second wind deflectors, with each slot corresponding to a locking block.

[0007] Preferably, a plurality of ball joint seats are fixedly installed at the bottom of the lifting panel, and a plurality of telescopic inner rods are respectively fixedly connected to the bottom of the plurality of ball joint seats. A telescopic rod is fixedly installed inside each of the plurality of fixed sleeves, and the moving ends of the plurality of telescopic rods are respectively fixedly connected to the bottom of the plurality of telescopic inner rods.

[0008] Preferably, anti-sinking posts are slidably provided on both sides of the plurality of anti-sinking pads, and locking bolts are threaded on both sides of the top of the plurality of anti-sinking pads, with the plurality of locking bolts respectively tightly fitting the surfaces of the plurality of anti-sinking posts.

[0009] Preferably, the surfaces of the two first wind deflectors and the two second wind deflectors are all provided with honeycomb-shaped ventilation holes.

[0010] Preferably, a tilt sensor is fixedly installed on the top of the landing panel, and the surface of the landing panel is provided with an anti-slip texture.

[0011] Preferably, a controller is fixedly installed at the bottom of the lifting panel, and the controller is electrically connected to the pressure sensor, tilt sensor and telescopic rod respectively.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model achieves multi-angle rotation of the support leg through a ball joint seat and adjusts the length of the telescopic inner rod by driving the telescopic rod. It can adapt to complex terrain with unevenness or large slopes, solving the problem of poor adaptability of existing fixed legs and single-degree-of-freedom structures. At the same time, the anti-sinking foot pads, together with the adjustable anti-sinking columns, can flexibly increase the support area according to the softness of the ground. And the position is fixed by locking bolts, which effectively prevents sinking on soft ground such as soil and grass, thus improving stability.

[0013] 2. In this utility model, the first and second windproof guide plates are combined into an enclosed structure through the combination of card blocks and slots. Combined with honeycomb ventilation holes, the crosswind kinetic energy is dispersed, reducing the drone's take-off and landing deviation caused by crosswinds and reducing the risk of collision. At the same time, relying on the linkage between the tilt sensor and the controller, the telescopic rod is automatically driven to complete the leveling calibration, replacing manual operation, improving the leveling efficiency and accuracy, and solving the problems of low efficiency and poor accuracy of manual leveling. Furthermore, the anti-slip texture of the take-off and landing panel and the real-time force monitoring of the pressure sensor further ensure the stability and safety of the drone's take-off and landing process.

[0022] This utility model discloses a safe take-off and landing platform device for unmanned aerial vehicles (UAVs) in complex terrain. The surfaces of the two first wind deflector plates 6 and the two second wind deflector plates 7 are all provided with honeycomb-shaped ventilation holes 14.

[0023] This utility model discloses a safe take-off and landing platform device for unmanned aerial vehicles in complex terrain. The top of the take-off and landing panel 1 is fixedly installed with an angle sensor 15, and the surface of the take-off and landing panel 1 is provided with anti-slip texture 16 to monitor the tilt of the take-off and landing panel 1 in real time and improve the anti-slip degree of the take-off and landing panel 1.

The controller 17 combines the force information of each support point fed back by the pressure sensor 5 and automatically controls the extension and retraction of the corresponding telescopic rod 11 until the take-off and landing panel 1 reaches a horizontal state. The anti-slip texture 16 enhances the friction between the UAV and the take-off and landing panel 1. The pressure sensor 5 continuously monitors the force of each support leg to avoid tilting or sinking caused by single-point overload. The honeycomb ventilation holes 14 disperse the crosswind kinetic energy while the wind deflector forms a barrier, reducing the interference of airflow on the take-off and landing of the UAV.
