Problems solved by technology

[0004] The operator usually holds the remote control to control the drone wirelessly; affected by the operator's actual operation proficiency, once the balance of the entire drone is not controlled, it is affected by the special structure of the drone, especially the arm The wing 3 on the 2 is located at the end of the arm 2, and the position of the wing 3 is the most vulnerable. Once it touches the ground and crashes, the wing 3 is very easy to break

Embodiment 1

[0038] An unmanned aerial vehicle disclosed by the present invention includes a body 1 and a plurality of arms 2. In this embodiment, the number of arms 2 is four, and the four arms 2 are evenly distributed around the body 1. The arms 2 deviate from The end of the body 1 is provided with wings 3, and each wing 3 is driven forward and reverse by a motor.

[0039] One end of the machine arm 2 is hinged to the body 1 through the hinge shaft 4, the hinge shaft 4 is provided with a torsion spring 5, and the body 1 is provided with four through holes 8 corresponding to the wings 3, the number is also four, and the torsion spring 5 is used to drive The arm 2 is turned over to the side of the body 1 and the wing 3 is close to the outside of the body 1 . After the arm 2 is folded, the wing 3 enters the through hole 8 correspondingly.

[0040] On each wing 3, a telescopic power assembly 7 is installed, and the telescopic power assembly 7 selects a cylinder, and a limit hole 6 is provide...

Embodiment 2

[0043]Embodiment 2: The difference from Embodiment 1 is that the following technical solutions are added. The body 1 is provided with a sliding groove 15 and a trigger groove 16. One end of the sliding groove 15 runs through the body 1 near the hinge point of the machine arm 2. On the other side, a protective rod 17 is provided for sliding in the sliding groove 15, and one end of the triggering groove 16 communicates with the inside of the sliding groove 15, and the other end communicates with the side wall of the body 1, and a triggering rod 19 is provided for sliding in the triggering groove 16 to protect The end of the rod 17 is provided with a first inclined guide surface 18, and the end of the trigger lever 19 is provided with a second inclined guide surface 20, the first inclined guide surface 18 is offset against the second inclined guide surface 20, and the trigger rod 19 deviates from the second inclined guide surface. The end of the surface 20 protrudes from the outer...

Abstract

The invention relates to an unmanned aerial vehicle, which includes a body and a plurality of arms, the plurality of arms are evenly distributed around the body, the end of the arm facing away from the body is provided with a wing, and one end of the arm is hinged by a hinge shaft On the body, a torsion spring is provided on the hinge shaft, and the torsion spring is used to drive the arm to turn over to one side of the body and make the wing close to the outside of the body; it also includes a telescopic power assembly installed on the wing, the A limiting hole is provided on the outer wall of the machine body, and the telescoping head of the telescopic power assembly can be inserted into the limiting hole to keep the machine arm stretched; the telescopic power assembly can be controlled by the remote controller to perform telescopic action. The invention has the effect of greatly reducing the damage to the wings when the plane crashes.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. [0003] Traditional UAV structure see figure 1 , its structure includes a body 1, a plurality of arms 2 are installed on the body 1, and a plurality of arms 2 form a circular array centered on the middle of the body 1, one end of the arm 2 is connected to the body 1, and the other end extends to the body 1 In addition, the end of the arm 2 facing away from the body 1 is provided with a motor and a wing 3, and the motor drives the wing 3 to rotate; in actual use, the motor drives the wing 3 to rotate, the wing 3 stirs the air, and the airflow is dir...
