Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to a propeller storage bin and an unmanned aerial vehicle thereof. Background Art

[0002] At present, a vertical take-off and landing fixed-wing UAV has been launched on the market. It combines the advantages of fixed-wing UAV and multi-axis UAV, not only ensuring the flight performance of the UAV, but also solving the problem of being restricted by the take-off and landing site. However, this type of UAV often simply superimposes the fixed-wing UAV and the multi-axis UAV, uses the relevant structure of the multi-axis UAV to perform vertical take-off and landing, and switches to fixed-wing flight mode after take-off. However, the multi-axis propellers of current UAVs are directly exposed, which produces very large flight resistance, greatly increases the energy consumption of the UAV, and significantly reduces the corresponding flight time and maximum flight speed. At the same time, the exposed propellers increase its volume, seriously affecting its appearance, and the packaging volume and transportation costs also increase significantly; and the storage cavity formed after storage affects the overall shape of the fuselage, making it easy for airflow to generate vortices when passing through the fuselage storage cavity, affecting the flight.

[0003] For example, the patent application with application number CN202021563670.1 includes a fuselage, propellers fixedly arranged at the front and rear ends of the fuselage, and multiple vertical take-off wings, which are rotatably arranged on both sides of the fuselage; and the fuselage is provided with a receiving slot for accommodating the vertical take-off wing, and the receiving slot is provided with a cover plate; a detection device and a driving device are also provided in the receiving slot, and the detection device detects the position of the vertical take-off wing in the receiving slot, and the driving device drives the cover plate to close the receiving slot according to the signal of the monitoring device; after the receiving slot accommodates the vertical take-off wing, the cover plate closes the receiving slot to form a streamlined fuselage, which will not affect the subsequent flight of the UAV, thereby reducing flight resistance, increasing the low-speed operation safety of the UAV, and improving the flight performance of the UAV; it also protects the vertical take-off wing after being stored; so that it is not damaged by external factors.

[0004] However, when the above-mentioned drone is in use, if the servo motor and the position detection device are used to cooperate to make the flying wing stop at a fixed angle after it stops, there is a situation where the servo motor rotates at a large angle and the position detection device needs to gradually determine the angle of the flying wing, thereby reducing the drone's efficiency in storing the flying wing. If the flying wing is fixed in position by causing the flying wing to rotate under force due to collision with the smooth structural layer of the receiving groove, there is a situation where the smoothness of the smooth structural layer decreases after multiple collisions and frictions between the flying wing and the receiving groove, causing the flying wing to wear, thereby reducing the drone's storage effect on the flying wing. It is urgent to design a propeller storage bin and a drone thereof to solve the above-mentioned problem. Utility Model Content
