Problems solved by technology
[0002] At present, quadrotor UAVs have been widely used in the commercial field or in the field of life; for traditional quadrotor UAVs, the design and layout of its power mechanism make the internal space of the quadrotor UAV fuselage unfavorable for loading and unloading. big other equipment
When the traditional quadrotor UAV is in the working flight state or idle non-working state, the quadrotor UAV is in an extended state as a whole, which takes up a relatively large space and is not convenient for the storage and transportation of the quadrotor UAV.

Embodiment Construction
[0062] Such as figure 1 As shown, it includes a fuselage 1, an arm mechanism 2, and a rotor mechanism 3, such as figure 1 , 2 As shown, the structures installed on both sides of the fuselage 1 are the same. For one side of the fuselage 1: one end of the two arm mechanisms 2 is symmetrically installed on one side of the fuselage 1, and the other ends are respectively equipped with rotor mechanisms. 3.
[0063] Such as image 3 Shown, above-mentioned rotor mechanism 3 has the blade 8 that makes quadrotor UAV fly.
[0064] Such as Figure 5 As shown, the above-mentioned machine arm mechanism 2 includes a first sleeve 17, a second sleeve 16, a hollow ball 15, a hemispherical shell 10 and a swing rod 9, as figure 2 As shown, wherein the first sleeve 17 is installed on the side of the fuselage 1; as Figure 5 As shown, one end of the second sleeve 16 is installed in the first sleeve 17 by sliding fit, and the other end is equipped with a hollow ball 15; the hemispherical shel...

The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a foldable four-rotor unmanned aerial vehicle, which includes a fuselage, an arm mechanism, and a rotor mechanism. It can swing to the four directions of the vertical state, as far as possible to meet the actual situation that the quadrotor UAV needs to be folded. When the unlocking bar releases the rotation limit of the hemispherical shell, the third sliding bar drives the third rack to move, and the third rack drives the second gear to rotate counterclockwise through the first gear and the rotating shaft; the counterclockwise rotation of the second gear , so that the first rack drives the first limiting plate to move upward, and the second rack drives the second limiting plate to move downward, so that the first limiting plate and the second limiting plate can release the first sleeve , the limit of the second sleeve, and then the second sleeve can slide freely in the first sleeve; finally, after the pendulum is folded into a vertical state by swinging, the purpose of reducing the space occupied by the quadrotor UAV is achieved .
Description
technical field [0001] The invention belongs to the technical field of drones, in particular to a foldable quadrotor drone. Background technique [0002] At present, quadrotor UAVs have been widely used in the commercial field or in the field of life; for traditional quadrotor UAVs, the design and layout of its power mechanism make the internal space of the quadrotor UAV fuselage unfavorable for loading and unloading. Great other equipment. When the traditional quadrotor UAV is in the working flight state or idle non-working state, the quadrotor UAV is in an extended state as a whole, which takes up a relatively large space and is not convenient for the storage and transportation of the quadrotor UAV. In order to take up less space for the quadrotor drone in an idle non-working state, it is necessary to design a foldable quadrotor drone; at the same time, in order to ensure that the quadrotor drone is mounted It can be stored together with the quadrotor UAV, so the foldabl...
