Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicles (UAVs), and in particular to a UAV. Background Art

[0002] With the continuous advancement of technology, smart devices have also seen rapid growth. Drones use wireless remote sensing technology to control the flight path of an aircraft. Cameras installed on drones can be used to survey specific areas. To ensure stable flight, drones are typically equipped with multiple symmetrical sets of propellers, each connected to a drive motor that provides direct power. During flight, different sets of propellers rotate in different directions. Therefore, propellers can be categorized as forward-propellers or reverse-propellers, depending on their rotational direction. During flight, drone propellers often collide and become damaged due to improper operation. Therefore, propellers are typically detachable from the drone's fuselage to facilitate replacement. However, the inventors have discovered that current multi-rotor drones have multiple propellers with identical structures and shapes. When replacing damaged propellers, they often get installed the wrong way around: a forward propeller is installed on a reverse-propeller motor, or a reverse propeller is installed on a forward-propeller motor. This can cause the drone to malfunction. Moreover, the arms and fuselage of traditional drones usually do not have error-proofing designs. Due to the lack of error-proofing designs, it takes a long time to debug the drones. Utility Model Content

[0003] Based on this, in order to solve the problem that the forward and reverse propellers are easily installed incorrectly, the utility model provides a drone, and its specific technical solution is as follows:

[0004] A drone, comprising

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with its embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0033] like Figure 1 As shown in ˉ5, an unmanned aerial vehicle in one embodiment of the present invention includes a fuselage 1, wherein the fuselage 1 is provided with a plurality of positive propellers 2 and a plurality of reverse propellers 3, and the fuselage 1 is used to drive the positive propellers 2 and the reverse propellers 3 to rotate; the positive propellers 2 are provided with a plurality of first anti-foolproofing blocks 4 arranged along the counterclockwise direction around the central axis of the positive propellers 2, and the fuselage 1 is provided with a second anti-foolproofing block 5, and the first anti-foolproofing block 4 is clamped with the second anti-foolproofing block 5; the reverse propellers 3 are provided with a plurality of third anti-foolproofing blocks 6 arranged along the clockwise direction around the central axis of the reverse propellers 3, and the fuselage 1 is provided with a fourth anti-foolproofing block 7, and the third anti-foolproofing block 6 is clamped with the second anti-foolproofing block 5.

[0034] In the aforementioned drone, the third anti-misalignment blocks 6 are arranged in a clockwise direction, while the first anti-misalignment blocks 4 are arranged in a counterclockwise direction. This prevents the forward propeller 2 from being installed in the position of the reverse propeller 3, and vice versa. This prevents the forward propeller 2 and the reverse propeller 3 from being installed in the wrong position. This drone solves the problem of the forward propeller 2 and the reverse propeller 3 being easily installed incorrectly.

The second anti-fouling block 5 is installed on the rotor of the first motor 12, and the fourth anti-fouling block 7 is installed on the rotor of the second motor 13. In this way, by installing both the second anti-fouling block 5 and the fourth anti-fouling block 7 on the rotor, anti-fouling is achieved while the forward propeller 2 and reverse propeller 3 can also rotate.
