Description
Technical Field
The invention relates to the technical field of aircraft airbag mounting equipment, in particular to an aircraft airbag mounting device.
Background
An important recovery mode of the unmanned aerial vehicle at the present stage is a mode of combining a recovery umbrella and a buffer air bag, wherein the buffer air bag can reduce the speed of the unmanned aerial vehicle from 6-7m/s to 0 in 100ms on the premise of not damaging the structure of the unmanned aerial vehicle as much as possible. The whole working process of the buffer air bag is as follows: when the recovery umbrella is opened for about 5-10s, the buffer air bag starts to be inflated, the air bag completes inflation before the unmanned aerial vehicle falls to the ground, the air bag is deflated at the moment of falling to the ground, and meanwhile, the speed of the unmanned aerial vehicle is reduced to 0. The opening and closing of the airbag cover plate in the whole process is critical, and according to the overall requirements, the airbag cover plate opening and closing mechanism needs to meet the following two basic requirements: firstly, the cover plate of the air bag should be firmly closed before the air bag is inflated, so that the unmanned aerial vehicle is ensured to have a smooth outer surface; and secondly, the air bag is required to be quickly opened before or after starting to inflate, so that the air bag is not prevented from rushing out of the unmanned aerial vehicle.
In order to ensure that the unmanned aerial vehicle has a smooth outer surface and simultaneously ensure the normal operation of the air bag, the air bag cover plate generally adopts the following schemes: firstly, a strong magnet is used for restraining a cover plate, before an air bag works, the strong magnet adsorbs the cover plate to a cover plate mounting frame to ensure that the outer surface of the unmanned aerial vehicle is smooth, after the air bag begins to be inflated, the adsorption force of the magnet is overcome by the expansion of the air bag, and then the cover plate is pushed open, and the method can simultaneously meet two basic requirements of an opening and closing mechanism but has the problem of electromagnetic compatibility, namely, the magnet can seriously influence a control system of the unmanned aerial vehicle; secondly, the thorn structure is used, the joint surfaces of the cover plate and the mounting frame are made into thorn structures, so that the cover plate and the mounting frame can be jointed together through mutual occlusion of thorns, but the thorn structures are difficult to process, the matching tolerance of the thorn structures is difficult to ensure, and the biting force of the thorn structures is difficult to ensure the larger overload resistance and the expansion effect of the air bag; thirdly, the cover plate is driven to be opened and closed through the electric control steering engine, but the scheme increases the weight of the opening and closing mechanism and reduces the reliability.
