Description

Technical Field

[0001] This application relates to the field of drone flight assistance technology, and in particular to a fixed-wing drone flight assistance device. Background Technology

[0002] With the increasing diversification of people's lives and the growing maturity of drone technology, drones are being used more and more widely in fields such as environmental monitoring, agricultural plant protection, aerial photography, firefighting, surveillance, and reconnaissance. Fixed-wing drone takeoff aids are devices that assist drones in taking off. Small fixed-wing drones typically use a hand-launch method. The operator uses arm strength to throw the drone, giving it an initial velocity and allowing it to fly.

[0003] In existing technologies, the hand-launching method for assisting flight can easily damage the drone and makes it difficult to control the flight direction and angle. Therefore, we propose a fixed-wing drone flight assistance device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that use hand-launching for flight assistance, which can easily damage the drone and make it difficult to control the flight direction and angle. Therefore, this invention proposes a fixed-wing drone flight assistance device.

[0005] The fixed-wing UAV flight aid device provided in this application adopts the following technical solution:

[0006] A fixed-wing unmanned aerial vehicle (UAV) flight aid device, comprising:

[0007] Support;

[0008] Support plates are provided, and two support plates are fixedly installed on the top of the support.

[0009] The support frame is rotatably mounted on two support plates. A catapult mechanism is installed inside the support frame to assist the drone in taking flight.

[0010] There are two baffles, both of which are fixedly installed on the top of the support frame, and both baffles are provided with guide grooves.

[0011] Elastic ropes are provided, and one end of each elastic rope is fixedly connected to the inner wall of one side of the support frame.

[0012] Furthermore, a movable seat is slidably installed inside the support frame, and a screw is rotatably installed on the support frame. The screw is threadedly connected to the movable seat. A second motor is fixedly installed on the outside of the support frame. The output shaft of the second motor is fixedly connected to one end of the screw. When the second motor is turned on, the screw drives the movable seat to move horizontally.

[0013] Furthermore, two first sliding grooves are formed on one side of the inner wall of the support frame. A buffer plate is slidably installed in each of the two first sliding grooves. A damping spring is fixedly connected to each of the two buffer plates. One end of each damping spring is fixedly connected to one side of the inner wall of the two first sliding grooves. The two damping springs and the two buffer plates can provide a buffering effect for the sliding rod.

[0014] Furthermore, a second inclined block is fixedly installed on one inner wall of the support frame, and a rectangular hole is opened on one side of the slide rod and one side of the movable seat. The rectangular hole communicates with the slot. The second inclined block cooperates with the first inclined block. When the second inclined block presses against the first inclined block, the second inclined block drives the first inclined block to move vertically downward.

[0015] Furthermore, a second sliding groove is provided on the bottom inner wall of the mounting groove, and a first inclined block is slidably installed in the second sliding groove. A compression spring is fixedly connected to the bottom of the first inclined block, and one end of the compression spring is fixedly connected to the bottom inner wall of the second sliding groove. A slot is provided at the bottom of the sliding rod, and the slot cooperates with the first inclined block. When the first inclined block is engaged with the slot, the first inclined block can position the sliding rod.

[0016] Furthermore, the ejection mechanism includes a slide rod, a mounting groove is provided on the top of the movable seat, the slide rod is slidably installed in the mounting groove, a slide block is fixedly connected to the top of the slide rod, and the other ends of multiple elastic ropes are fixedly connected to the outside of the slide rod.

[0017] Furthermore, a first motor is fixedly installed on the outer side of the support plate, and a rotating shaft is rotatably installed on both support plates. One end of each rotating shaft is fixedly connected to the outer side of the support frame. The output shaft of the first motor is fixedly connected to one end of the rotating shaft. When the first motor is turned on, the rotating shaft drives the support frame to rotate.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. When the first motor is turned on, the first motor drives the rotating shaft to rotate, which in turn drives the support frame to rotate, thereby adjusting the flight angle of the drone. By adjusting the position of the base, the takeoff direction of the drone can be adjusted.

[0020] 2. When the second motor is turned on, the screw drives the movable seat to move horizontally. When the movable seat moves to a certain position, the second inclined block presses against the first inclined block. When the first inclined block separates from the slot, multiple elastic ropes drive the slide rod and slide seat to reset instantly through deformation force. Thus, the slide seat can launch the drone for flight assistance.

[0021] This invention can assist the drone in flight by launching it during use, thus avoiding damage to the drone. It also allows for easy adjustment of the drone's flight direction and angle. The structure is simple and easy to use. Attached Figure Description

[0035] Reference Figure 3 and Figure 4 The ejection mechanism includes a slide rod 11. A mounting groove 10 is provided on the top of the movable seat 9. The slide rod 11 is slidably installed in the mounting groove 10. A slide block 12 is fixedly connected to the top of the slide rod 11. The other ends of multiple elastic ropes 16 are fixedly connected to the outer side of the slide rod 11. Two first slide grooves 13 are provided on one side of the inner wall of the support frame 4. A buffer plate 15 is slidably installed in each of the two first slide grooves 13. A damping spring 14 is fixedly connected to each of the two buffer plates 15. One end of each damping spring 14 is fixedly connected to one side of the inner wall of the two first slide grooves 13.
