Description

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) equipment technology, specifically to a foldable UAV take-off and landing platform and an automatic control method. Technical Field

[0002] This invention belongs to the technical field of low-altitude unmanned aerial vehicle (UAV) take-off and landing support equipment, specifically relating to a UAV take-off and landing platform that can be automatically folded and quickly deployed, particularly suitable for fixed-point take-off and landing operations of UAVs used in low-altitude logistics delivery and security patrol. Background Art

[0003] With the rapid development of the low-altitude economy, the application of drones in civilian logistics and urban security patrols is becoming increasingly widespread, leading to a continuous increase in the demand for corresponding drone take-off and landing platforms. Currently, most conventional drone take-off and landing platforms on the market adopt a one-piece structure with fixed welding, resulting in a fixed overall size that cannot be folded, retracted, or adjusted.

[0004] The existing technology has the following obvious drawbacks: First, the fixed platform is large in size and occupies a lot of space, making it difficult to install in small areas such as building exteriors, shop walls, and rooftops; Second, the platform cannot be folded up and is easily exposed to wind, rain, dust, and aging, and its protruding structure can easily cause safety hazards such as bumps and falls; Third, conventional platforms are mostly manually deployed and adjusted, with low automation, and the deployment and folding operations are cumbersome and inefficient; Fourth, the support structure of ordinary flat-panel take-off and landing platforms is simple, and the downward airflow generated by the drone's take-off and landing can easily cause the platform to sway, resulting in poor take-off and landing stability and a tendency for the drone to deviate and slip.

[0005] Therefore, there is an urgent need to develop a drone take-off and landing platform that can be automatically folded and stored, has strong stability when unfolded, occupies little space, and is adaptable to installation in multiple scenarios, while also providing an automated control method to solve various defects in existing technologies. Summary of the Invention

[0006] The purpose of this invention is to overcome the problems of large footprint, inability to automatically retract, low degree of automation, poor support stability, and weak scene adaptability in the existing technology, and to provide a foldable drone take-off and landing platform and automatic control method. The device has a reasonable structural design, strong linkage transmission stability, and can realize fully automatic unfolding and closed storage, which greatly reduces the space occupied in the storage state. At the same time, the supporting control method has clear logic and can accurately complete the device start-up and shutdown actions.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A foldable unmanned aerial vehicle (UAV) take-off and landing platform includes an external protective shell, a linkage telescopic drive mechanism, and a foldable take-off and landing platform assembly. The linkage telescopic drive mechanism is fixedly installed inside the external protective shell and includes a fixed base, a lower support connecting plate, an upper traction connecting plate, an electric telescopic push rod, a linkage adapter plate, and a hinged connector. The fixed base is rigidly connected to the inner wall of the external protective shell. The lower support connecting plate and the upper traction connecting plate are rotatably connected to the fixed base and the linkage adapter plate respectively at both ends through the hinged connectors. The two ends of the electric telescopic push rod are respectively hinged between the fixed base and the upper traction connecting plate, forming a triangular linkage support structure. The foldable take-off and landing platform assembly is fixedly connected to the outer end face of the linkage adapter plate.

[0008] Furthermore, the folding landing platform assembly includes a central support main board, two symmetrically arranged sets of folding wing plates, a flip-drive electric push rod, and a hinge assembly; a set of folding wing plates is respectively rotatably mounted on the left and right sides of the central support main board through the hinge assembly.

[0009] Furthermore, one end of each set of flip-drive electric push rods is hinged to the bottom of the central bearing main board, and the other end is correspondingly hinged to the inner wall of the folding wing plate, for driving the folding wing plate to flip and open around the hinged hinge assembly.

[0010] Furthermore, the fixed base, lower support connecting plate, upper traction connecting plate, and linkage adapter plate cooperate to form a four-bar linkage transmission mechanism. Through the change of the extension and retraction stroke of the electric telescopic push rod, the linkage adapter plate is driven to complete the horizontal extension and vertical retraction actions along the preset motion trajectory.

[0011] Furthermore, the central support main board and the folding wing plate are uniformly provided with ventilation holes on their surfaces, which can guide the downward airflow generated by the drone's take-off and landing and prevent the airflow from swirling and causing the fuselage to shake; the four edges of the central support main board and the folding wing plate are integrally formed with anti-fall-off limiting barriers to prevent the drone from sliding and deviating.

[0012] Furthermore, the bottom of the outer protective shell is fixedly equipped with adjustable support feet, which can be adjusted according to the installation plane to ensure that the equipment is placed horizontally and improve installation stability.

[0013] This invention also provides an automatic control method for a foldable unmanned aerial vehicle (UAV) take-off and landing platform, comprising the following steps: S1. After receiving the deployment command from the remote control terminal or local controller, the control system first controls the electric telescopic push rod to extend outward, drives the four-bar linkage to move synchronously, and pushes the folding lifting platform assembly horizontally from the inside of the outer protective shell to the preset working position. S2. After the platform extends into position, the position sensor sends a signal to the control system. The control system then synchronously controls two sets of flip-drive electric push rods to extend, pushing the two folding wing plates on both sides to flip upwards to a horizontal state, precisely splicing them with the central support main board to form a complete flat lifting platform. S3. After the drone lands smoothly on the landing platform and completes the loading, unloading and parking of the cargo, the equipment receives the storage and closing command. S4. The control system first controls the retraction of the flip drive electric push rod, which drives the two folding wing plates on both sides to flip down and retract to a vertical state in a synchronous manner. S5. After the folding wing panels are retracted, the control system controls the electric telescopic push rod to retract, driving the entire landing platform assembly to smoothly return to the interior of the outer protective shell, completing the fully enclosed storage and protection. Beneficial effects

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention adopts a four-bar linkage combined with a triangular stable support transmission structure, which has strong mechanical transmission rigidity, stable support after the platform is unfolded, and no shaking or deviation will occur during the take-off and landing of the drone, and has excellent wind resistance performance. 2. The entire unit can be completely folded and stored inside the protective housing, reducing its volume by more than 60% after storage, greatly reducing the space occupied during installation. When not in use, it can be stored in a fully enclosed manner, which is waterproof and dustproof, extending the service life of the equipment. 3. The entire process is driven by an electric push rod, which is fully automatic and requires no manual operation. With the help of automated control logic, it can be remotely controlled to unfold and retract with one button. It has a high degree of automation and is easy to use. 4. The platform is equipped with a ventilated perforated structure, which can effectively guide the airflow during take-off and landing, and avoid air turbulence affecting the smooth landing of the drone. The edge limiting barriers can effectively prevent the fuselage from slipping, making it safer to use. 5. The overall modular structure design makes assembly and disassembly convenient, and it can be adapted to various installation scenarios such as building exterior walls, rooftops, shop platforms, and park ground, making it widely applicable.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1-3 As shown, a foldable UAV take-off and landing platform includes an outer protective shell 1, a linkage telescopic drive mechanism, and a foldable take-off and landing platform assembly. The linkage telescopic drive mechanism is fixedly installed in the internal cavity of the outer protective shell 1. The fixed base 2 is welded and fixed to the inner wall of the outer protective shell 1. The lower support connecting plate 3 and the upper traction connecting plate 4 are both connected to the fixed base 2 and the linkage adapter plate 6 respectively by means of pin hinges. The electric telescopic push rod 5 is inclined and hinged between the fixed base 2 and the upper traction connecting plate 4, forming a stable triangular support transmission structure.

[0019] The folding landing platform assembly is fixedly installed on the outside of the linkage adapter plate 6. A folding wing plate 8 is movably installed on the left and right sides of the central bearing main board 7 through metal hinges. Two sets of flip-drive electric push rods 9 are symmetrically arranged on the bottom sides of the central bearing main board 7, and the two ends of the push rods are hinged to the main board and the wing plate respectively.

[0020] During actual use and assembly, the outer protective shell 1 is leveled and fixed in the installation position using the adjustable support feet 10 at the bottom. After the equipment is powered on, it can enter the standby working state. When it needs to be unfolded for use, the electric telescopic push rod 5 extends, pushing the linkage mechanism to rotate outward, smoothly pushing the entire lifting platform out of the shell; then the flip-driven electric push rod 9 extends, flattening the two folding wing plates 8 and splicing them into a complete lifting plane.

[0021] After the drone takes off and lands, the electric push rods are retracted in reverse order, which can retract the wing panels and the platform, and store the entire structure inside the shell to achieve closed protection.

[0022] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
