An unmanned aircraft, abbreviated as drone and in english as UAV, is an aircraft that is operated by means of a radio remote control device and a self-contained program control device, or is operated autonomously, either completely or intermittently, by an onboard computer. The unmanned aerial vehicle is wide in application field at present and has general application in military use, civil use and other aspects. For military use, unmanned aerial vehicles divide into reconnaissance aircraft and target drone. In civil aspects, unmanned aerial vehicles are widely applied to aerial photography, agriculture, plant protection, miniature self-timer, express transportation, disaster relief, wild animal observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, movie and television shooting and the like.
In some operation tasks, for example disaster relief, military reconnaissance, scientific surveying, because the environment is comparatively complicated, unmanned aerial vehicle will face the test through narrow and small topography at the operation in-process, because above operation task has higher requirements to functions such as unmanned aerial vehicle's continuation of the journey load stability simultaneously again, consequently, the volume that reduces unmanned aerial vehicle in a taste improves its flexibility inadvisable.
Disclosure of Invention
The invention is made to solve the above problems, and an object of the invention is to provide a quad-rotor unmanned aerial vehicle with foldable arms.
The invention provides a quad-rotor unmanned aerial vehicle with foldable arms, which is characterized by comprising the following components: the surface of the machine body is square; the four arms are respectively connected to the four sides of the machine body and are connected with the machine body through springs and hinges; and the propeller is arranged on the horn and consists of a motor bracket, a motor fixed on the motor bracket and a blade connected with the motor.
In the four rotor unmanned aerial vehicle with foldable arms provided by the invention, the four rotor unmanned aerial vehicle can also have the following characteristics: wherein, the screw propeller is a ducted screw propeller.
In the four rotor unmanned aerial vehicle with foldable arms provided by the invention, the four rotor unmanned aerial vehicle can also have the following characteristics: wherein, the support is composed of two crossbeams which are mutually vertical in a cross shape.
Action and Effect of the invention
According to the four-rotor unmanned aerial vehicle with the foldable horn, the horn is connected with the body through the spring and the hinge, so that the extension and contraction of the spring and the turnover of the hinge can be controlled by controlling the thrust of the propeller, and the folding and unfolding of the horn can be further controlled; because the screw comprises motor support, motor and paddle, so can the motor independently drive the paddle rotatory, need not extra driver, saved the cost.
Therefore, the four-rotor unmanned aerial vehicle with the foldable arms is simple in structure, the function of deforming the foldable arms in the flight process of the unmanned aerial vehicle can be realized without an additional driver, and the deformation effect is good. In addition, the time required by the opening and closing deformation of the horn is short, the size of the folded horn is reduced by 50% relative to the size of the stretched horn, so that the size of the folded horn is reduced, the advantages of long endurance, large load and high stability can be kept through a narrow space which can not be penetrated by the existing universal non-deformable four-axis gyroplane, and the folded horn can play an important role in tasks such as rescue, survey and the like.

Detailed Description
In order to make the technical means and functions of the present invention easy to understand, the present invention is specifically described below with reference to the embodiments and the accompanying drawings.
Example (b):
fig. 1 is a schematic structural view of a quad-rotor drone with a foldable horn according to an embodiment of the present invention, and fig. 2 is a side structural view of the quad-rotor drone with a foldable horn according to an embodiment of the present invention.
As shown in fig. 1 and 2, a four-rotor drone 100 with foldable arms of the present embodiment includes: fuselage 10, horn 20, and propeller 30.
The surface of the body 10 is square.
The number of the horn 20 is 4, which is respectively connected to four sides of the body 10 and is symmetrical about the center of the body 10, and is connected to the body 10 by the spring 40 and the hinge 50, the spring 40 and the hinge 50 pull the horn 10 to a vertical position when the propeller 30 stops operating, and the horn 10 is unfolded again when the propeller 30 starts and the thrust of the propeller 30 exceeds the tension of the spring 40.
The surface of the horn 20 is square and has the same side length as the surface of the body 10, and the size of the folded horn 20 is half of the size of the extended horn 20, that is, the size is reduced by 50%.
The hinge 50 is disposed at the connection position of the fuselage 10 and the horn 20, and under the expansion and contraction of the spring 40 and the turning action of the hinge 50, the horn 20 can be turned over under the thrust action of the propeller 30, thereby completing the folding and unfolding of the horn 20.
The propeller 30 is mounted on the arm 10 and is composed of a motor bracket 301, a motor (not shown) fixed on the motor bracket 301, and a blade 302 connected to the motor, and the rotation of the blade 302 is driven by the motor.
In this embodiment, the propeller 30 is a ducted propeller, and the support 301 is composed of two cross-shaped cross beams perpendicular to each other.
The working principle of the four-rotor unmanned aerial vehicle with the foldable horn is as follows:
in the four-rotor unmanned plane with foldable horn 100 of the present invention, when the motor stops operating, the propeller 30 stops operating, at this time, the thrust provided by the propeller 30 is zero, the horn 20 will be pulled to the vertical position to realize folding under the action of the spring 40 and the hinge 50, when the motor operates, the propeller 30 starts and when the thrust of the propeller 30 exceeds the tension of the spring 40, the horn 20 will be unfolded again.
Effects and effects of the embodiments
According to the four-rotor unmanned aerial vehicle with the foldable horn, the horn is connected with the body through the spring and the hinge, so that the extension and contraction of the spring and the turnover of the hinge can be controlled by controlling the thrust of the propeller, and the folding and unfolding of the horn can be further controlled; because the screw comprises motor support, motor and paddle, so can independently drive the paddle rotation through the motor, need not extra driver, save the cost.
According to the collapsible four rotor unmanned aerial vehicle of horn that this embodiment relates to, because the screw that adopts is duct formula screw, so efficiency is higher, and the mobility is stronger.
Consequently, the collapsible four rotor unmanned aerial vehicle of horn of this embodiment simple structure need not extra driver and just can realize the function that unmanned aerial vehicle flight in-process folding horn warp, and warp respond well. In addition, the time required by the opening and closing deformation of the horn is short, the size of the folded horn is reduced by 50% relative to the size of the stretched horn, so that the size of the folded horn is reduced, the advantages of long endurance, large load and high stability can be kept through a narrow space which can not be penetrated by the existing universal non-deformable four-axis gyroplane, and the folded horn can play an important role in tasks such as rescue, survey and the like.
