Description

High altitude unmanned aerial vehicle compels to land auxiliary device

The technical field is as follows:

the invention belongs to the field of unmanned aerial vehicle auxiliary devices, and particularly relates to a forced landing auxiliary device for an aerial unmanned aerial vehicle.

Background art:

an unmanned aircraft, abbreviated as "drone", and abbreviated in english as "UAV", is an unmanned aircraft that is operated by a radio remote control device and a self-contained program control device, or is operated autonomously, either completely or intermittently, by an onboard computer.

Drones tend to be more suitable for tasks that are too "fool, dirty, or dangerous" than are manned aircraft. Unmanned aerial vehicles can be classified into military and civil applications according to the application field. For military use, unmanned aerial vehicles divide into reconnaissance aircraft and target drone. In the civil aspect, the unmanned aerial vehicle + the industry application is really just needed by the unmanned aerial vehicle; at present, the unmanned aerial vehicle is applied to the fields of 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, disaster relief, film and television shooting, romantic manufacturing and the like, the application of the unmanned aerial vehicle is greatly expanded, and developed countries actively expand industrial application and develop unmanned aerial vehicle technology.

At present, the crowd of unmanned aerial vehicles in China increases gradually, and because what unmanned aerial vehicle realized is well remote control, unmanned aerial vehicle breaks away from the work outside the operator's sight range often, runs into proruption situation, has the risk of crash.

However, the existing unmanned aerial vehicle is not complete in technology, and particularly, effective measures are difficult to take for the sudden situation of the unmanned aerial vehicle in the flight process, so that huge loss is caused to the owner; also some producers have been equipped with the auxiliary device that descends for unmanned aerial vehicle, but most structure is complicated, and is with high costs, is difficult to popularize.

The invention content is as follows:

in order to solve the technical problem, the invention provides an auxiliary device for forced landing of an aerial unmanned aerial vehicle, which comprises: the device comprises an installation accessory, a bearing plate, a locking accessory, an ejection accessory, a paraglider, an execution accessory and a control accessory, wherein the installation accessory is arranged at two ends of the bottom surface of the bearing plate, a warning lamp is arranged at one end of the front side surface of the bearing plate, the bearing accessory is hollow, the execution accessory and the control accessory are arranged inside the bearing accessory, the execution accessory comprises an actuator, a positioning device and a storage battery, the control accessory comprises a gyroscope accelerometer and a time relay, the actuator is arranged in the middle of the bearing plate, the locking accessory is arranged at the upper end of the actuator, a rectangular support table is arranged between the locking accessory and the actuator, the paraglider is arranged at the upper end of the locking accessory, the paraglider comprises an umbrella cover and springs, the springs are arranged on four side surfaces of the umbrella cover, the ejection device is arranged on the bottom surface of, a supporting rod spring is arranged between the supporting rods.

According to the further technical scheme, the positioning device adopts a Beidou positioning device.

According to the further technical scheme, the control accessory is connected with a motor of the unmanned aerial vehicle.

According to the further technical scheme, the actuator is meshed with the locking accessory in a normal state.

Compared with the prior art, the invention has the beneficial effects that:

(1) the invention adopts the design of the paraglider, and can effectively protect the machine body when falling.

(2) The device has simple structure, low cost and convenient popularization.

Description of the drawings:

the accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention and not to limit the invention. In the drawings:

FIG. 1 is an external structural view of the present invention;

FIG. 2 is a view showing the folding of the paraglider according to the present invention;

fig. 3 is a structural view of the ejection accessory of the present invention;
