Description

Technical Field

[0001] The utility model relates to the field of coaxial UAVs, in particular to a coaxial UAV power sleeve interlocking structure. Background Art

[0002] A drone refers to an unmanned aircraft that is controlled by a radio remote control device and a self-contained program control device, including civil drones and military drones. With the development of technology, drone technology has gradually matured, and its specific applications are in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting, creating romance and so on.

[0003] A common traditional coaxial drone on the market today is a drone with two sets of rotors installed on the same vertical axis. These two sets of rotors rotate in opposite directions. The advantage of this design is that they can offset each other's anti-torque, making the drone more stable in the air, while also improving its maneuverability and controllability.

[0004] However, the above-mentioned traditional coaxial drones still have certain problems. For example, the drone may become unstable when flying at high speed or encountering severe weather conditions such as strong winds. In order to ensure the performance of the drone, more mechanical components are often required, which not only increases the complexity of the drone, but also increases the manufacturing cost. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a coaxial UAV power sleeve interlocking structure to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coaxial UAV power sleeve interlocking structure, comprising a UAV body, a locking shaft center column rotatably installed on the top of the UAV body, and a connecting block installed on the top of the locking shaft center column, a first limit plate fixedly installed on the bottom end of the connecting block, and a second limit plate fixedly installed on the outer wall of the connecting block, a fixed column fixedly installed on the top of the locking shaft center column, and a limit slide groove corresponding to the first limit plate and the second limit plate is opened in the fixed column, a coaxial motor is threadedly installed on the outer wall of the connecting block, and a wing is fixedly installed on the outer wall of the coaxial motor.

[0007] By adopting the above technical solution, the movement of the motor is restricted, which effectively reduces the shaking during flight, allowing the drone to maintain a good flight state even in complex environments. Since the number of mechanical parts is reduced, it will be more convenient and quicker during daily maintenance and repair. Although the structure adopts an advanced interlocking design, the overall structure is simple, which helps to reduce production costs and allow more people to enjoy the convenience brought by high technology.

[0008] Furthermore, the fixing column, the first limiting plate and the second limiting plate are all provided with threaded holes, and the threaded holes all pass through the fixing column, the first limiting plate and the second limiting plate.

[0009] By adopting the above technical solution, bolts can be used to fix the first limiting plate and the second limiting plate to their corresponding fixing columns through the threaded holes.

[0010] Furthermore, multiple groups of first limiting plates are symmetrically installed at the end of the connecting block, and multiple groups of second limiting plates are symmetrically installed on the outer wall of the connecting block, and the multiple groups of first limiting plates and the multiple groups of second limiting plates are respectively distributed at the four corners of the connecting block.

[0011] By adopting the above technical solution, the limiting effect provided by the four corners further improves the overall stability of the connecting block after installation.

[0012] Furthermore, multiple groups of first limiting plates and multiple groups of second limiting plates are installed on the top and bottom ends of the connecting block, and the multiple groups of first limiting plates and multiple groups of second limiting plates on the top and bottom ends of the connecting block are symmetrically designed.

[0013] By adopting the above technical solution, a coaxial structure is formed by connecting the top end and the bottom end to the lock shaft center column.

[0014] Furthermore, the first limiting plate and the second limiting plate are both L-shaped, and the limiting sliding groove corresponds to the shorter side of the L-shaped design.

[0015] By adopting the above technical solution, the installation of the connecting block and the lock shaft center column is simple and quick.

[0016] Furthermore, multiple groups of fixed columns are installed at equal angles on the outer wall of the end of the lock shaft center column, and the limiting slide grooves of the fixed columns corresponding to the multiple groups of first limiting plates are facing away from the second limiting plates, and the limiting slide grooves of the fixed columns corresponding to the multiple groups of second limiting plates are designed to be at a right angle to the angle between the first limiting plates.

[0017] By adopting the above technical solution, multiple groups of first limiting plates can be aligned with the limiting slots of the corresponding fixed columns and directly slidably installed, so that multiple groups of second limiting plates can be installed into the limiting slots of the corresponding fixed columns at the same time.

[0018] In summary, the present invention has the following beneficial effects:

[0019] This utility model effectively reduces shaking during flight by limiting the movement of the motor, allowing the drone to maintain a good flight state even in complex environments. Since the number of mechanical parts is reduced, daily maintenance and repairs will be more convenient and quicker. Although the structure adopts an advanced interlocking design, the overall structure is simple, which helps to reduce production costs and allow more people to enjoy the convenience brought by high technology.
