Description
Technical Field
The invention belongs to the field of mechanical design of unmanned aerial vehicles, and particularly relates to a novel unmanned aerial vehicle paddle protective cover.
Background
Nowadays, unmanned aerial vehicle is more extensive in the application in each field, and in order to realize some more complicated tasks, unmanned aerial vehicle has to develop towards bigger volume, and the bulky means bigger quality, and in order to realize bigger load, unmanned aerial vehicle's paddle also need constantly to be increaseed, and the motor needs higher rotational speed, and this has also brought very big potential safety hazard, and unmanned aerial vehicle injures people's incident and frequently takes place.
Therefore, it is an urgent problem to those skilled in the art to develop a structure capable of reliably protecting the blades of the unmanned aerial vehicle.
Disclosure of Invention
In order to solve the problems, the invention discloses a novel unmanned aerial vehicle blade protective cover.
In order to achieve the purpose, the invention provides the following technical scheme:
a novel unmanned aerial vehicle blade protection cover comprises an annular main body, an installation support and a bottom net; the mounting support comprises spokes and a motor connecting piece; the number of the spokes is odd, and the spokes are uniformly distributed on the surface of the motor connecting piece by taking the motor connecting piece as the center; the annular main body is arranged on a circle formed by the outer ends of the spokes in a matching way; the bottom layer net is arranged on the lower end face of the annular main body and filled between every two adjacent spokes.
Further, the number of spokes is 5.
Further, a circle of protrusions are arranged on the outer side of the annular main body along the circumferential direction; the protrusion is a protrusion with a wide outer part and a narrow inner part.
Further, the annular main body comprises an upper layer main body and a lower layer main body which are distributed up and down; the upper layer main body and the lower layer main body are both annular and are fixed through nylon columns.
Further, the annular main body and the spokes are made of light and deformation-resistant materials; the bottom layer web is made of a material that is fine and has high tensile strength.
Further, the annular body and the spokes are made of carbon plate.
The novel unmanned aerial vehicle blade protective cover provided by the invention has the following characteristics:
1. the annular main body adopts a double-layer design, and is not easy to deform when being collided compared with the existing layer;
2. the mounting support is connected with the peripheral annular main body by 5 spokes to seal the protective cover, so that the spokes are mainly pulled when the unmanned aerial vehicle horizontally flies and collides with an obstacle, and possible instability of the protective cover under the condition of pressure is solved; meanwhile, the odd spokes avoid the resonance of the unmanned aerial vehicle under the influence of the airflow of the blades;
3. the sectional area of the spokes in the horizontal direction is smaller than that of 3 spokes due to the selection of 5 spokes and larger than that of 7 spokes, so that the unmanned aerial vehicle has excellent aerodynamic performance and is not easy to cause great damage to other objects when the unmanned aerial vehicle crashes, and the 5 spokes enable the bottom net woven on the spokes to be uniformly distributed so that the bottom net can provide protection at the edge of the protective cover compared with 3 spokes, turbulence generated by the 7 spokes near the spokes is smaller, the bottom net can timely limit the rotation of the blades when the blades fall down abnormally, and the damage to ground personnel and property is reduced;
4. the motor connecting piece has the function of connecting spoke, connecting unmanned aerial vehicle horn pipe clamp concurrently for unmanned aerial vehicle's the maintenance of being convenient for rationally assembled, and processing is simple.
Therefore, compared with the prior art, the unmanned aerial vehicle with the large blades solves the contradiction between the requirement of reliable safety protection of the unmanned aerial vehicle with the large blades and the limited power redundancy of the unmanned aerial vehicle, and ensures that the blades of the unmanned aerial vehicle can be prevented from being interfered by objects from the lower part and the horizontal direction in the flying process under the condition of not causing overlarge flying resistance of the unmanned aerial vehicle as much as possible.
