Description

Technical Field

[0001] This utility model relates to the technical field of safe parking and transportation platforms for large multi-rotor drones, specifically to a drone landing platform. Background Technology

[0002] With the rapid advancement of drone technology, its applications in agricultural plant protection, industrial inspection, film and television shooting, and consumer entertainment have experienced explosive growth. As a supporting facility, automated drone airports, by integrating autonomous take-off and landing systems with intelligent fast-charging modules, completely eliminate the need for manual intervention, significantly improving operational efficiency and equipment turnover. The core challenge of this system lies in the precise positioning during the recovery process—due to environmental factors and equipment performance limitations, drones often experience centimeter-level positional deviations during landing, necessitating the configuration of intelligent correction devices to achieve millimeter-level precise repositioning.

[0003] Currently, there are two main technical approaches to centering solutions on the market: The first involves using four independent push rods in conjunction with a multi-motor collaborative drive system. Centering and position correction of the drone are achieved by controlling the displacement of these push rods. However, the multi-motor structure is somewhat complex and difficult to control. Furthermore, the lack of a fixing mechanism after the push rods extend and retract due to the independent motors poses a risk of secondary displacement of the drone, which is detrimental to drone transportation. The second approach utilizes an industrial robotic arm for grasping and positioning, but this requires a six-axis robotic arm, visual positioning, and other multiple systems, resulting in high overall implementation costs. These bottlenecks severely restrict the large-scale commercial application of automated airports. Therefore, there is an urgent need for a low-cost, integrated centering and fixing solution that combines positioning correction and physical locking into a single action through mechanical linkage design. Utility Model Content

[0004] The purpose of this invention is to provide a drone landing platform that can achieve centering, positioning, correction, and physical locking of drones at low cost, while having a simple and reliable structure and being easy to maintain.

[0005] To achieve the above objectives, a drone landing platform is provided, comprising a base with its upper surface serving as a drone landing pad, a front-to-back centering mechanism, a left-to-right centering mechanism, a push rod assembly, and a controller; the front-to-back centering mechanism includes a first motor, a first threaded rod, and a first lower slider assembly disposed on the lower side of the base, and a first upper slider assembly disposed on the upper surface of the base, the first lower slider assembly having two sets driven by the first motor and the first threaded rod to achieve opposite or opposite movement; the first upper slider assembly having two sets including left and right centering rods, the upper surface of the base having a first strip groove, and a protrusion at the upper end of the first lower slider assembly passing through the first strip groove and connecting to the lower bottom surface of the left and right centering rods;

[0006] The push rod assembly includes a bracket, a push rod gripper, and a first electrically controlled telescopic component. The bracket is disposed on the upper surface of the left and right centering rods, the push rod gripper is hinged to the top of the bracket, and the first electrically controlled telescopic component is used to drive the push rod gripper to rotate and fix the drone.

[0007] The front and rear centering mechanism includes a second motor, a drive shaft, a second threaded rod, a third threaded rod, and a second lower slider assembly, as well as a second upper slider assembly disposed on the upper surface of the base. Both the second and third threaded rods are equipped with two sets of second lower slider assemblies. The drive shaft is driven by the second motor and is parallel to the first threaded rod. The two ends of the drive shaft drive the second and third threaded rods to rotate via commutators, respectively, enabling the two sets of second lower slider assemblies to move towards or away from each other. The second upper slider assembly has two sets including front and rear centering rods. The upper surface of the base is provided with a second strip groove. The second lower slider assemblies on the same side of the second and third threaded rods pass through the second strip groove via connecting rods and are connected to both ends of the front and rear centering rods.

[0008] The first electrically controlled telescopic component, the first motor, and the second motor are electrically connected to the controller.

[0009] Furthermore, the front and rear centering rods and the left and right centering rods are each provided with a number of clamping assemblies. Each clamping assembly includes a short plate. One end of the short plate is fixed to the front and rear centering rods by bolts, and the other end is provided with a threaded hole facing the center of the base. The threaded hole is provided with bolts for fixing the drone's feet.

[0010] Furthermore, the upper surface of the base is provided with several lifting rings around its perimeter.

[0011] Furthermore, the lifting ring is mounted on the rotating base.

[0012] Furthermore, a camera mounting plate is provided on the corner of the upper surface of the base, and a camera is mounted on the camera mounting plate. The camera is electrically connected to the controller.

[0013] Furthermore, the upper surface of the base is vertically provided with a plurality of second electrically controlled telescopic rods, the top of the second electrically controlled telescopic rods is provided with a support plate, the support plate is provided with a support block for supporting the cantilever of the UAV, and the second electrically controlled telescopic rods are electrically connected to the controller.

[0014] Furthermore, a pressure sensor is provided between the support plate and the support block, and the pressure sensor is electrically connected to the controller.

[0015] Furthermore, the support plate is semi-cylindrical, and a buffer layer is provided on its upper surface.

[0016] Furthermore, the buffer layer is a silicone layer or a sponge layer.

[0017] Furthermore, it also includes a client that is remotely connected to the controller.

[0018] Principles and advantages:

[0019] 1. The UAV platform in this solution is operated remotely via remote communication. The platform's movement status is fed back to the client in real time, facilitating real-time monitoring of data and movement status.

[0020] 2. After the drone lands on the platform, a front-to-back centering mechanism and a left-to-right centering mechanism are used to push the drone to the exact center of the platform. When the drone is in the center position, bolts from the front-to-back centering mechanism and the left-to-right centering mechanism are used to lock and secure the drone at its four feet. The drone frame is then pressed and locked using push rod grips. This reliably secures the drone to the platform for easy transport. Simultaneously, the second electrically controlled telescopic rod extends and retracts. The support plate and support block at the top of the second electrically controlled telescopic rod support the drone's cantilever, further securing the drone and ensuring its safety during transport.

[0021] 3. This solution features a streamlined structural design, is practical and reliable, and easy to maintain. It eliminates the need for four independent push rods and a multi-motor collaborative drive system to center the UAV and correct its position. Furthermore, it eliminates the need for an industrial robotic arm for grasping and positioning. Therefore, compared to existing technologies, this solution is more streamlined and lower in cost.
