[0002] Drone parachutes are the last line of defense to ensure the safety of drones and onboard equipment. At present, the technical foundation of active safety measures for drones at home and abroad is weak. Mechanical and signal transmission failures often occur in various sensors and subsystems of drones. Flight control software and remote control equipment control software also often have system loopholes, resulting in frequent crashes of drones during use. Especially when the drone reaches a certain flight altitude, the drone has a fast speed and a large impact during the fall. If it falls to the ground, the drone is basically scrapped. When the landing site conditions do not allow descent or in an emergency, the drone generally uses a parachute to land. Therefore, there is a special need for a drone parachute recovery device that is easy to carry.

[0003] However, the existing parachute recovery devices for drones that are easy to carry are generally fixedly connected to the drone body. If the parachute system fails, it is inconvenient to maintain. When the drone does not need parachute recovery, the parachute recovery device fixed on the drone will affect the flight speed of the drone. When the recovery parachute opens, the drone will be affected by the impact force of the parachute deployment, which may damage the drone. Utility Model Content

When the limiting column 311 follows the slider 312 to move to the appropriate position, it pushes the movable plate 306, and one end of the movable plate 306 is embedded in the first square groove 301. Then the slider 312 is released, and the first spring 310 loses the force of the limiting column 311 and is deformed and reset, driving the limiting column 311 to move. Secondly, one end of the limiting column 311 is embedded in the inside of the recovery base plate 1, and the movable plate 306 limits the umbrella box 2. At this time, the umbrella box 2 is installed on one side of the surface of the recovery base plate 1.

[0026] Furthermore, the buffer mechanism 4 includes a rubber strip 401, a second spring 402, a sliding column 403, a second limit block 404, a cylinder 405, a circular groove 406 and a connecting plate 407. One side of the surface of the recovery base plate 1 is fixedly connected with the rubber strip 401, the second spring 402, the sliding column 403, the second limit block 404, and the second limit block 404. The cylinder 405 is installed on one side of the surface of the sliding column 403. The cylinder 405 is provided with a circular groove 406 inside. The surface of the cylinder 405 is fixedly connected with the connecting plate 407. Through the arrangement of the rubber strip 401, the second spring 402, the sliding column 403, the second limit block 404, the cylinder 405, the circular groove 406 and the connecting plate 407, first, the connecting plate 407 is fixedly installed on the top of the drone. When the drone performs parachute recovery, the recovery base plate 1 is subjected to landing The second spring 402 absorbs the force of the recovery base plate 1, thereby reducing the impact on the connecting plate 407. At this time, the buffering of the force of the recovery base plate 1 on the connecting plate 407 during the deployment of the parachute is completed. Through the arrangement of the slide post 403, the slide post 403 can limit the recovery base plate 1 and the connecting plate 407 when the second spring 402 is deformed, thereby preventing lateral movement between the recovery base plate 1 and the connecting plate 407, thereby preventing instability during recovery. Through the arrangement of the rubber strip 401, the rubber strip 401 itself has elasticity, which can reduce the impact of the recovery base plate 1 on the connecting plate 407 during the deployment of the parachute, and at the same time prevent the second spring 402 from being too large and affecting the stability of the recovery.

Through the setting of the second limit block 404, the second limit block 404 limits the sliding column 403 inside the circular groove 406 to prevent the sliding column 403 from separating from the cylinder 405 when moving.

[0029] Working principle: When installing the umbrella box 2, first align the sliding groove 307 at the bottom of the umbrella box 2 with the first limit block 303, then align the bolt 308 with the first square groove 301, then push the umbrella box 2 into the inside of the recovery base plate 1, and tighten the nut 309 through the threaded connection between the bolt 308 and the nut 309, so that the umbrella box 2 is fixed on one side of the surface of the recovery base plate 1, and then push the slider 312 to make the slider 312 slide inside the second square groove 304, and the slider 312 drives the limit column 311 to move, and the limit column 311 squeezes the first spring 310, and the first spring 310 is subjected to force. After the first cam 310 is released, the first spring 311 is released, and the first spring 310 loses the force of the limiting post 311 and is deformed and reset, thereby driving the limiting post 311 to move. Secondly, one end of the limiting post 311 is embedded in the interior of the recovery base plate 1, and the movable plate 306 limits the umbrella box 2. At this time, the umbrella box 2 is installed on the surface side of the recovery base plate 1, and the shaft post 311 is used to release the first spring 310. 02, the shaft column 302 limits the movable plate 306 and supports the rotation of the movable plate 306. First, the connecting plate 407 is fixedly installed on the top of the drone. When the drone performs parachute recovery, the recovery base plate 1 is subjected to the impact force of the parachute opening, and the sliding column 403 is subjected to the force of the recovery base plate 1 and moves in the circular groove 406 inside the cylinder 405. The second limit block 404 is subjected to the force of the sliding column 403 and moves with the sliding column 403. At the same time, the second spring 402 is deformed by the force of the recovery base plate 1. The second spring 402 absorbs the force of the recovery base plate 1 to reduce the The impact of the connecting plate 407 is completed. At this time, the buffering of the force of the recovery base plate 1 on the connecting plate 407 when the parachute is deployed is completed. Through the setting of the sliding column 403, the sliding column 403 can limit the recovery base plate 1 and the connecting plate 407 when the second spring 402 is deformed, so as to avoid lateral movement between the recovery base plate 1 and the connecting plate 407, which causes instability during recovery. Through the setting of the rubber strip 401, the rubber strip 401 itself has elasticity, which can reduce the impact force of the recovery base plate 1 on the connecting plate 407 when the parachute is deployed, and at the same time avoid the second spring 402 from being too large and affecting the stability of recovery.
