Detailed Description

The present invention will be further described with reference to fig. 1 to 4.

The utility model relates to an unmanned aerial vehicle, it includes the frame.

The utility model relates to a frame, like figure 1, the frame includes bottom plate 11, horn 13, motor cabinet 14 and foot rest 15, and foot rest 15 sets up the downside at horn 13, like figure 2, and bottom plate 11 is provided with at least three arm link 12, and the quantity of arm link 12 matches with the quantity of horn 13. Specifically, unmanned aerial vehicle's function module is installed on bottom plate 11, and unmanned aerial vehicle's motor is installed on motor cabinet 14, and motor cabinet 14 is installed on horn 13, and horn 13 is installed with arm connection end 12. Further, for making the frame atress balanced, unmanned aerial vehicle's functional module should install in the middle part position of bottom plate 11, and each arm link 12 should encircle bottom plate 11 evenly setting along the circumference, and is corresponding, and motor cabinet 14 also is along circumference evenly distributed. For example: the number of the arm connecting ends 12 is three, and the three arm connecting ends 12 are located at three vertexes of the regular triangle; the number of the arm connection ends 12 is set to four, and the four arm connection ends 12 should be located at four vertices of a square.

One end of the horn 13 is used for being detachably mounted with the arm connecting end 12, the other end of the horn 13 is used for being detachably mounted with the motor base 14, and maintenance cost can be reduced by adopting a split type detachable frame structure. If adopt integral type rack construction, the frame appears damaging then needs to replace whole frame, and adopts split type detachable rack construction, and the part that the maintenance only need replace the damage part.

As shown in fig. 3, in some embodiments of the present invention, the arm 13 and the foot rest 15 are integrated, so that the time for assembling and disassembling the foot rest 15 is saved, a connection structure is not required to be designed, the structure of the frame is simplified, the weight of the frame is reduced, and the cost is reduced. In addition, when unmanned aerial vehicle takes off and land, foot rest 15 can not take place to shift, and intensity is high.

In some embodiments of the present invention, the frame should be as light as possible in order to overcome the dead weight of the fuselage, and therefore the bottom plate 11 is made of glass fiber board. Common frame materials comprise plastics and carbon fibers, wherein the plastics are low in density, light in weight, low in price and easy to manufacture, but the strength and the rigidity are not large, and screws are easy to loosen when the paddle rotates at a high speed. The carbon fiber has low density, high strength and rigidity, stable flight and damping effect, and is difficult to machine and high in cost. The glass fiber board is synthesized by glass fiber materials and high-heat-resistance composite materials, has high mechanical property and dielectric property, good heat resistance and moisture resistance and good processability.
