Unmanned-aerial-vehicle shock absorption gasbag and unmanned-aerial-vehicle gasbag shock absorption device

Abstract

The invention discloses an unmanned-aerial-vehicle shock absorption gasbag. A gasbag is of a cylindrical structure after air inflation, and air releasing holes are formed in the two circular side faces, and are covered with replaceable air releasing films. The tolerant pressure value of the air releasing films ranges from 200 kPa to 300 kPa. Based on the gasbag, the invention also discloses an unmanned-aerial-vehicle gasbag shock absorption device; the size of an air inflation part of the unmanned-aerial-vehicle gasbag shock absorption device is small, the air inflation speed can be automatically adjusted, and the problem that as the air inflation speed cannot be adjusted through a traditional air inflation part, the gasbag is not inflated fully or inflated excessively is solved; startingand stopping of an air blower are automatically controlled through a photosensitive light sensor, and controlling is easy and reliable.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle shock-absorbing airbag and an unmanned aerial vehicle airbag shock-absorbing device. Background technique [0002] With the development and application of UAVs, in the landing buffer mode of the UAV recovery system, the airbag buffer device is increasingly popular due to its light weight, foldable into a small volume storage before inflation, and easy realization of small deceleration and overload. favored by machine designers. At present, the traditional solutions for inflating parts of airbags are gas cylinders, pyrotechnics, or inflating pumps, etc. The start and stop of the inflating parts are controlled by the flight control computer according to the preset program. [0003] The main defect is that the traditional scheme has advantages such as relatively simple circuit and easy implementation, but there are mainly the following shortcomings...

AI Technical Summary

Problems solved by technology

The large volume of the gas cylinder is inconvenient to install and the cost is high; the explosive device is small in size but is easily restricted by environmental conditions and other factors, such as temperature, humidity, etc., and the reliability is not high; the air pump is large in size and the inflation speed is uncontrollable Inflation or insufficient inflation; the start and stop of the inflatable parts in the traditional solution is controlled by the flight control computer according to the preset program, and it cannot sense the surrounding environment to deal with complex landing terrain; the size of the traditional vent hole is not easy to control, and if it is too large, the airbag will not be fully filled Affect the cushioning effect, if it is too small, it will easily lead to the inability to quickly deflate and make the body bounce instantly when it hits the ground
