Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicles (UAVs) and their auxiliary equipment, specifically relating to a UAV release platform based on a flywheel self-stabilizing mechanism, which is used to improve the safe release and take-off performance of UAVs in complex environments. Background Technology

[0002] With the widespread application of drones in surveying, agricultural plant protection, power line inspection, logistics distribution, and film and television shooting, higher requirements have been placed on the reliability and safety of drones. Traditional drone release platforms usually adopt fixed structures or simple mechanical release methods. When installed on dynamic carriers such as vehicles and ships, they are susceptible to external vibrations and interference, leading to unstable attitude during the release process, which in turn affects the safe takeoff of the drone and may even cause equipment damage or mission failure. Summary of the Invention

[0003] The purpose of this invention is to provide a drone release platform based on a flywheel self-stabilizing mechanism. Through the flywheel self-stabilizing mechanism and related structural design, relying on the pure mechanical gyroscope effect, the platform can achieve real-time horizontal correction under external interference, ensuring the accuracy and safety of the drone release process. At the same time, the bottom of the support is designed with a universal installation interface, which is suitable for installation on various carriers and has good versatility and reliability.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a drone release platform based on a flywheel self-stabilizing mechanism, comprising: a self-stabilizing platform (2), a flywheel (1), a drone gripper (6), a motor (3), a lead screw (4), and a support (5). The self-stabilizing platform (2) is provided with a flywheel (1); the drone gripper (6) is used to grip and release the drone; the motor (3) and the lead screw (4) are used to drive the slip ring to realize the opening and closing action of the gripper; the support (5) is used to fix the platform to a vehicle, ship, or other carrier. The flywheel (1) is installed below the self-stabilizing platform (2), and the angular momentum generated by its high-speed rotation enables the platform to be horizontally corrected in real time when subjected to external vibration or tilting interference. The control system detects the precession of the flywheel, determines the direction and amplitude of the interference, and adjusts the platform attitude in a timely manner. The motor (3) drives the lead screw (4) to rotate, so that the drone gripper (6) installed on the slip ring performs gripping and release control, thereby realizing the safe release of the drone.

[0005] The beneficial effects of this invention are mainly reflected in the following aspects: the self-stabilizing effect generated by the flywheel ensures that the platform can maintain a horizontal state in various complex environments; the motor-driven lead screw transmission structure realizes precise control of the UAV gripper, ensuring accurate release action; the platform has a simple structure and is suitable for various carriers, with high versatility and expandability, and can meet the needs of different application scenarios.

[0014] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.

[0015] like Figure 1 As shown, a UAV release platform based on a flywheel self-stabilizing mechanism mainly includes a self-stabilizing platform (2), a flywheel (1), a UAV gripper (6), a motor (3), a lead screw (4), and a support (5). The support (5) is used to fix the platform to a vehicle, ship, or other carrier. The bottom of the support (5) is provided with universal mounting holes, which are compatible with the mounting interfaces of vehicles and other carriers, ensuring that the platform has a stable foundation during operation.

[0016] like Figure 3 and Figure 4As shown, the flywheel (1) is installed below the self-stabilizing platform (2), and its shaft is connected to the self-stabilizing platform (2) through a universal support assembly. The flywheel (1) rotates at high speed around the vertical axis to generate stable angular momentum. When the self-stabilizing platform (2) is subjected to external vibration or tilting disturbance, the overturning torque generated by the external disturbance is canceled by the reverse torque generated by the precession of the flywheel (1), thereby limiting the tilt angle of the platform. At the same time, the control system is selected as an auxiliary component. Based on the precession of the flywheel, the external disturbance is judged, and the flywheel speed is adjusted to assist the attitude adjustment, so as to realize the self-adaptability of the platform attitude. However, the basic steady state of the platform is generated by the mechanical precession of the flywheel.

[0017] like Figure 5 As shown, the UAV gripper (6) uses a mechanical transmission structure to achieve gripping and release. The UAV gripper (6) and the slip ring (9) are connected by a connecting rod (8). The UAV gripper (6) and the connecting rod (8) are connected by a revolute joint A (10). The connecting rod (8) and the slip ring (9) are connected by a revolute joint B (12). The UAV gripper (6) is radially installed on the edge of the self-stabilizing platform (2) through a revolute joint C (11). The UAV gripper (6) is arranged in a mirror image on both sides of the lead screw (4). The two UAV grippers (6) are identical in structure and connection method. During the opening and closing of the UAV gripper (6), the motor (3) drives the lead screw (4) to rotate, causing the slip ring to move up and down, which drives the gripper installed on the slip ring to perform gripping and release operations. Normally, in the standby state, the UAV gripper (6) is in the gripping state; when the UAV take-off command is received, the motor (3) drives the lead screw (4) to rotate, the UAV gripper (6) opens, and the UAV release operation is completed.

[0018] like Figure 6 As shown, during the release and takeoff of the UAV, the flywheel (1) continuously plays a self-stabilizing role, so that the self-stabilizing platform (2) remains stable on the vehicle, ship and other carriers, avoiding abnormal attitude of the UAV caused by the shaking of the carrier, and improving the safety of UAV takeoff and mission success rate.

[0019] like Figure 7 As shown, in other embodiments, the present invention can also add multiple sets of drone grippers or optimize the platform structure according to specific application needs to support the simultaneous release of multiple drones or adapt to different environmental conditions. For those skilled in the art, various improvements and variations can be made to the above embodiments without departing from the spirit and technical solutions of the present invention, and all such improvements and variations should be within the protection scope of the present invention.

[0020] The above embodiments are merely preferred embodiments of the present invention. Any equivalent substitutions and modifications made within the spirit and scope of the present invention should be considered as protected content of the present invention.
