Detailed Description

The invention discloses a novel inflatable shock-absorbing air bag system which comprises an air bag 1, an air bag installation interface 2, a fan 3, an electric regulator 4, a signal controller 5 and a power supply 6. The invention is used for a deceleration recovery system of a certain type of unmanned aerial vehicle. Because the steady speed that falls after the parachuting was retrieved can't make the equipment safety landing in the unmanned aerial vehicle, can cause unmanned aerial vehicle equipment damage, so in order to further reduce the speed of falling to the ground after the unmanned aerial vehicle parachuting was retrieved, reduce and fall to the ground and strike overload, need design a shock attenuation gasbag system and reduce the biggest overload, protection unmanned aerial vehicle equipment.

The device is characterized in that an air bag installation interface, a fan and an electric controller are sequentially installed at one end of an air inlet of an air bag, and then a signal controller and a power supply are sequentially installed at the other end of the electric controller.

This device is when out of operation state, and the gasbag is folded into the fritter and is installed in unmanned aerial vehicle gasbag cabin, and signal controller is in the closed condition, and the signal can not be received in the electricity accent, and voltage and electric current are zero, and the rotational speed of fan is zero.

When this device during operation, signal controller work, give the electricity signal of telecommunication, the fan begins the rotation, inflates for the gasbag by the gasbag air inlet, and gasbag volume is bigger and bigger under the atmospheric pressure effect struts unmanned aerial vehicle gasbag cabin cover, finally forms preset's shape. Then the fan lasts work and aerifys for the gasbag, and when unmanned aerial vehicle fell to the ground, gaseous by exhaust hole discharge in the gasbag, the impact kinetic energy when falling to the ground is consumed through the collision of gasbag and ground, reduces the biggest overload to protection unmanned aerial vehicle equipment.

The invention is further described in the following with reference to the accompanying figures 1-11 of the specification.

The side of the air bag mounting interface 2 is provided with two holes for passing through a screw, a nut and a gasket to connect the air bag 1 and the fan 3, and meanwhile, the air bag mounting interface 2 is connected with the air bag 1 through AB glue, so that a cylindrical opening on the air bag 1 is tightly connected with the side of the air bag mounting interface 2. The bottom of the air bag mounting interface 2 is provided with four round holes for penetrating screws, nuts and gaskets to be connected with the unmanned aerial vehicle umbrella cabin. The end of fan 3 has 3 aviation plugs for be connected with 3 aviation plugs of electricity accent 4. Wherein, the wind direction of the fan can be changed by changing the connection sequence of the aviation plugs. One end of the electric controller 4 is provided with 3 aviation plugs for being connected with 3 aviation plugs of the fan 3, the other end of the electric controller is connected with the signal controller 5 and the power supply 6, the electric controller is used for adjusting the rotating speed of the fan by adjusting voltage and current, the signal controller 5 is used for providing electric signals for the electric controller 4, so that the rotating speed of the fan 3 is controlled by the electric controller 4, and the power supply 6 is used for providing electric energy for the fan 3 and the electric controller 4.

Air inlet one end at gasbag 1 installs gasbag installation interface 2, fan 3 in proper order, transfers 4, signal controller 5, power 6, wherein connects through screw, nut and gasket between signal gasbag installation interface 2 and the fan 3, glues fixed connection through screw, nut, gasket and AB between gasbag 1 and the gasbag installation interface 2, connects through the aviation plug between fan 3 and the electricity transfer 4.
