An aircraft, as shown in FIGS. 1 and 2, includes a main body 100, a propeller 150, and a driving device 140 for driving the propeller 150, and further includes a center of gravity of the aircraft On the upper stabilizer bar 110, the stabilizer bar 110 is disposed at the upper end of the aircraft. In the present invention, since the aircraft is provided with a stabilizer bar 110 for the stable flight of the aircraft in the direction of its center of gravity, the stabilizer bar 110 can ensure its stability and balance during flight, making it safer to fly.

1 is a split view of the aircraft, the main body 100 of the aircraft together with the stabilizer bar 110 as a whole has a cone structure, and its internal weight is uniform, so that the center of gravity of the aircraft is on the center of gravity of the main body; and the aircraft and The center of gravity of the body 100 is in its center direction, so that the stabilizer bar 110 is disposed at the center of the body 100 to better stabilize the stabilizer bar 110 for the aircraft to fly stably.

2 is a cross-sectional view of the aircraft. Referring to FIG. 1, the driving device 140 is disposed in the main body 100. The propeller 150 is disposed below the driving device 140, and the propeller 150 is surrounded by the main body, so that the propeller 140 rotates. The air is discharged downward, and the main body 100 is provided with a plurality of uniformly distributed air inlets 131, thereby ensuring that the propeller 150 can normally enter the air and then rotate normally.

The main body includes an upper casing 120 and a lower casing 130. The upper casing 120 is centrally provided with a fixing hole for fixing the stabilizer bar 110, and the stabilizer bar 110 is provided with a limiting portion that cooperates with the fixing hole; The limiting portion of the stabilizer bar 110 is fixedly coupled to the fixing hole at the center of the upper casing 120, and the limiting portion securely fixes the stabilizer bar 110 to the upper casing 120.

The limiting portion is provided with a slot 111 axially to the stabilizer bar 110. As shown in FIG. 2, the limiting portion is provided with a slot 111 in the axial direction of the stabilizer bar, and the two sides of the slot 111 at the pressing limit portion are The side wall makes the limiting portion expand and contract, and the limiting portion is inserted into the fixing hole of the upper casing, and the upper casing is protruded, so that the grooved portion is not restricted by the fixing hole, and the original shape is restored, and then the fixing hole is fixed. The limit is set so that the stabilizer bar is firmly fixed; and it is easy to install and remove. Of course, the stabilizer bar can also be fixed in other ways, such as by a snap.

The aircraft further includes an sensing device for sensing an obstacle. As shown in FIG. 1, the sensing device is plural, and includes a first sensing device 160 for sensing an obstacle in a horizontal direction and a second sensing device for sensing an obstacle in a vertical direction. The sensing device 170 prevents the aircraft from flying too low and prevents the aircraft from being too close to the surrounding obstacles during flight. The sensing device is evenly disposed at the bottom of the lower casing 120, and an inductive device is disposed around the lower casing to prevent the aircraft from continuing to fly in the direction of obstacles. The sensing device is infrared sensing.

The driving device 140 is disposed in the upper casing 120. As can be seen from the figure, the driving device includes a driving motor, a driving gear fixed on an output shaft of the driving motor, a transmission gear meshing with the driving gear, and being fixed at a driven gear on the propeller, the driven gear meshes with the transmission gear, and a battery is fixed in the main body of the aircraft, and the battery is connected with the driving motor to supply power to the driving motor, and the output shaft of the driving motor rotates to drive the driving gear to rotate. The driving gear drives the transmission gear and the driven gear to rotate, thereby rotating the propeller, thereby realizing the flight of the aircraft. The flight of the aircraft is made more stable by the stabilizing action of the stabilizer bar during the flight of the aircraft. The lower casing 130 surrounds the propeller 150 and is disposed horizontally with the propeller 150 such that the propeller is prevented from being exposed.

As shown in FIG. 2, the upper casing 120 extends along the fixing hole with an extending portion 121 for socketing on the stabilizer bar 110.
