Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) equipment technology, specifically to a composite wing UAV with a vertical take-off and landing fixed wing. Background Technology
[0002] In layman's terms, drones are a general term for unmanned aerial vehicles. From a professional perspective, they refer to unmanned aerial vehicles that fly autonomously or remotely using radio remote control equipment or the aircraft's own flight control system. Through these technologies, drones can perform various types of tasks and are characterized by being retrievable and reusable.
[0003] In related technologies, compound-wing UAVs can perform tasks such as environmental monitoring, remote sensing, disaster area search and rescue, and emergency rescue in the civilian field. Currently, most compound-wing UAVs are driven by vertical propellers to rise to the ground. They are versatile and can take off in a variety of environments. Compared with ordinary UAVs, they are more practical and have a longer flight endurance.
[0004] However, most compound-wing drones have their throwing devices installed at the bottom of the fuselage. When throwing items, the items may collide with the landing gear. In addition, the bottom of most drones is where batteries and sensors are installed, making subsequent maintenance of the drone inconvenient. To solve the above problems, a compound-wing drone with a vertical fixed wing is proposed. Utility Model Content
[0005] In view of this, the present invention provides a vertical take-off and landing fixed wing for a compound wing UAV. The present invention allows emergency rescue items to be placed in the drop box by opening the compartment door. When it is necessary to drop items, the electronic lock is first unlocked, which causes the bottom of the drop box to lose support and open the drop box door, so that the emergency items can be dropped into the emergency rescue area. This prevents the dropped items from colliding with the landing gear when dropping items, and also facilitates the subsequent maintenance of the UAV.
[0006] To solve the above-mentioned technical problems, this utility model provides a vertical take-off fixed wing for a compound wing UAV, including fixed wings symmetrically arranged on the fuselage of the compound wing UAV, each fixed wing being provided with a vertical power frame, and a connector being provided at the bottom center of each fixed wing. The connector is installed close to the central axis of the fuselage of the compound wing UAV, and a deployment device is provided at the bottom of each connector. A pair of landing gears are symmetrically arranged along the fuselage axis at the bottom of the compound wing UAV fuselage.
[0007] Each connector includes a vertical plate that is connected to the fixed wing on the same side. The vertical plate is used to connect the flat plate to the fixed wing. A flat plate is provided at the bottom of the vertical plate, which is used to connect the vertical plate to the adjusting positioning rod.
[0008] Each plate has an adjustable positioning rod fixed at its bottom. The adjustable positioning rod is used to install throwing boxes of different lengths and widths. Each adjustable positioning rod has multiple positioning holes for installing bolts.
[0009] Each delivery device includes a clamp that mates with the adjusting positioning rod on the same side. The clamp is used to connect the delivery box to the adjusting positioning rod. Each clamp consists of two clamping plates, each with multiple mounting holes. The mounting holes are used to mate with the positioning holes for bolt connection. The mounting holes are also used to install bolts. The clamp and the adjusting positioning rod are connected by bolts after the mounting holes align with the positioning holes, thereby connecting the delivery box to the adjusting positioning rod, with the mounting holes and positioning holes mate.
[0010] The delivery device also includes a delivery box at the bottom of the clamp, which is used to deliver emergency rescue supplies. Inside the delivery box, a pair of delivery doors are rotatably installed at the bottom. The delivery doors are used to open the delivery box from the bottom. Each delivery door includes an upper door and a lower door. The upper door and the lower door are tenon-and-mortise fitted together. Multiple electronic locks are installed at the gap at the bottom of the upper door and the lower door to prevent the delivery doors from opening automatically.
[0011] One end of the electronic bolt lock is connected to the bottom of the upper door panel, and the other end is connected to the lower door panel.
[0012] The drop box has an openable door on the side away from the nose of the compound wing UAV. The door is used to place emergency supplies inside the drop box. The bottom of the door is hinged to the drop box, which makes it easy to open. The top of the door is equipped with a door lock to fix the door. The other end of the door lock is connected to the outer wall of the drop box.
[0013] The landing gear is in an inverted Y-shape, with several ventilation holes on each landing gear. These ventilation holes reduce wind resistance during flight and also dampen the compound-wing UAV during landing, reducing the impact force from the ground that could damage the electronic components of the compound-wing UAV. A shock absorber is fixedly installed at the bottom of each landing gear, further reducing the vibration experienced by the landing gear during landing, thereby protecting the internal electronic components of the compound-wing UAV and extending their service life. The shock absorber adopts a gas flow guiding design.
[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. By opening the cargo door, emergency rescue items can be placed in the drop box. When it is necessary to drop items again, the electronic lock is unlocked first, which causes the bottom of the drop door to lose support and open the drop door, so that the emergency items can be dropped into the emergency rescue area. This prevents the dropped items from colliding with the landing gear when dropping items, and also facilitates the subsequent maintenance of the drone.
[0015] 2. The connector should be installed close to the centerline of the drone fuselage to reduce the impact on flight attitude after the throwing device is loaded with emergency items, and also to reduce the stress on the fixed wings.
[0016] 3. Ventilation holes are used to reduce wind resistance during flight. Ventilation openings are also used to dampen vibrations when the compound wing UAV lands, thereby reducing the impact force from the ground that could damage the electronic components of the compound wing UAV during landing. Shock-absorbing plates are used to further reduce the vibration experienced by the landing gear during landing, thereby protecting the electronic components inside the compound wing UAV and improving the service life of the components.
