Detailed Description

The present invention will be described in further detail with reference to the drawings and the following detailed description.

Referring to fig. 1 to 2, the manned unmanned aerial vehicle anti-falling guide umbrella in the embodiment includes an umbrella body 1, an umbrella rope 2 arranged at the bottom end of the umbrella body 1, an opening arranged at the top end of the umbrella body 1, a first barrel bag 3 and a second barrel bag 4, wherein the first barrel bag 3 and the second barrel bag 4 are made of the same material as the umbrella body 1 and are made of the existing parachute material. The first barrel bag 3 is of a bag body structure with a triangular cross section and is communicated with the upper part and the lower part, namely the first barrel bag 3 is of an opening structure communicated with the upper part and the lower part, the second barrel bag 4 is of a bag body structure with a triangular cross section and an opening at the bottom end and the top end, wherein the bottom end of the first barrel bag 3 is communicated with the opening, namely the bottom end edge of the first barrel bag 3 is sewn with the opening edge at the top end of the umbrella body 1 to form a whole; meanwhile, the top end of the first barrel bag 3 is communicated with the bottom end of the second barrel bag 4, and the overall dimension of the first barrel bag 3 is larger than that of the second barrel bag 4.

Specifically, the height of the first barrel bag 3 in the embodiment is one third of the diameter of the umbrella body 1, and the length of the bottom edge of the first barrel bag 3 is one half of the height; the height of the second barrel bag 4 is half of the height of the first barrel bag 3, and the length of the bottom edge of the second barrel bag 4 is one third of the length of the bottom edge of the first barrel bag 3. It can be understood that, in practice, the specific external dimensions of each of the first barrel bag 3 and the second barrel bag 4 can be flexibly changed according to practical situations, such as the carrying capacity of the manned unmanned aerial vehicle and the size of the umbrella body 1. Similarly, in actual use, the external dimension of the guide umbrella can be correspondingly flexibly changed according to actual requirements so as to meet the use requirements.

In addition, referring to fig. 4, the guiding umbrella in this embodiment further includes a manned box 6 connected to the umbrella body 1, a power device (not shown in the figure) arranged on the manned box 6 and used for driving the wings 7 to rotate, and an umbrella box 5, wherein the wings 7 are installed on two sides of the manned box 6 and provide a supporting force for the manned box 6 to fly up, the umbrella box 5 is installed on the top end of the manned box 6, and the bottom end of the umbrella body 1 is connected to the manned box 6 through the umbrella box 5. It can be understood that the wings 7 and the corresponding power devices on the manned unmanned aerial vehicle can adopt the existing common unmanned manned structure, namely the existing wing mounting structure. In addition, in order to improve the comfort of passengers on the landing site, a landing frame 8 having a buffering function is mounted on the bottom end of the man-carrying case 6.

Referring to fig. 3, when the umbrella body 1 in the embodiment is unfolded and unfolded, under the action of the air power, the umbrella body can simultaneously play the following three functions of stabilizing the umbrella body:

A. at the moment that the umbrella body of the guiding umbrella is opened, due to the gravity action of the manned unmanned aerial vehicle, air sequentially enters the first barrel bag 3 and the second barrel bag 4 through the opening at the top of the umbrella body and correspondingly forms strong vertical airflow in the first barrel bag 3 and the second barrel bag 4, the flow rate of the vertical airflow in the umbrella body is several times of that of the airflow outside the umbrella body, and the influence of wind power and wind direction outside the umbrella body on the state of the umbrella body is greatly weakened according to the aerodynamic principle;

B. the first barrel bag 3 and the second barrel bag 4 can be rapidly formed under the action of vertical airflow to form two large and small triangular barrel bags, the barrel bags respectively form two windward surfaces and one leeward surface under the action of aerodynamic force, and the leeward surfaces of the barrel bags can generate acting force opposite to the windward surfaces under the action of the aerodynamic force, so that the influence of the windward airflow on the umbrella body can be greatly reduced, namely the influence of the wind force and the wind direction outside the umbrella on the vertical state of the guide umbrella can be further reduced;

C. the first barrel bag 3 and the second barrel bag 4 are respectively provided with a plurality of quadrilateral side surfaces, can generate the orientation, balance and stabilization effects similar to the empennages of airplanes and missiles under the action of aerodynamic force, and can play an important role in maintaining the vertical descending state of the guide umbrella.

To sum up, above-mentioned direction umbrella that has a barrel bag in this embodiment both can avoid the appearance that the umbrella body rises rapidly under the effect of aerodynamic, greatly reduces the interference of wind-force outside the umbrella, wind direction, can make the umbrella body remain stable vertical direction state again to guarantee manned unmanned aerial vehicle can not appear deviating and the phenomenon of swaying, have great meaning to manned unmanned aerial vehicle safety.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalent technologies, the present invention is also intended to include such modifications and variations.
