Description

A small manned aircraft anti-fall airbagTechnical Field

[0001] The invention belongs to the technical field of small manned aircraft, in particular to an anti-fall airbag.Background Art

[0002] IWith the continuous progress of science and technology, people's living standards are also constantly improving, so people have a higher pursuit of leisure life and travel quality, manned plane travel, flight experience, special scenic spots flight sightseeing and aerial photography, etc., have always been a pursuit of high-quality leisure life. In recent years, with the rapid development of aircraft technology, various types of aircraft continue to emerge, especially the application of small manned aircraft, more and more become the focus of research.

[0003] The existing aircraft are mainly divided into two categories: fixed-wing and rotary-wing. The traditional fixed wing has the advantages of fast flight speed and low energy consumption, but the wing structure is not strong enough to be easily damaged, the takeoff and landing requirements are high, and the takeoff and landing distance are long.

[0004] Rotary-wing aircraft has the advantages of convenient take-off and landing, but it has some disadvantages such as high energy consumption, low safety factor, poor load capacity, slow horizontal flight speed and easy crash.

[0005] Most of the existing manned aircraft do not have emergency escape devices, when flying at high altitude, if there is an emergency situation, can not ensure the safety of personnel. Therefore, how to provide a manned aircraft that can enable personnel to escape safely is an urgent problem for technicians in this field.Technical Solution

[0006] In order to solve the above problems, the invention provides a small manned aircraft anti-fall airbag, which is designed to intelligently and automatically pop-up anti-fall airbag at the bottom of the small manned aircraft to prevent the small manned aircraft from crashing or sinking into the water and effectively protect the safety of the manned aircraft when the height is not high, the parachute cannot fully play a role or falls into rivers, reservoirs, lakes and sea.

[0007] The technical scheme adopted by the invention is:

[0008] The utility model relates to a small manned aircraft anti-fall airbag, which comprises a shell, an airbag, a spring, a baffle, a connecting cloth, latex, a mounting part and an air outlet. The airbag is tightly folded in the shell, one end of the airbag is a connecting cloth, and the connecting cloth is provided with latex, which plays a buffering role to prevent the airbag from impacting the ground and causing local damage or rupture due to excessive force. One end of the air bag is the installation part, the side of the installation part is provided with a baffle plate, and the spring behind the baffle plate is provided. When the air pressure of the air bag is too large, the baffle plate is compressed by the spring and the gas is discharged through the air outlet.

[0009] Further, the mounting part comprises a mounting part housing, an inertial sensor, a controller, an air bag generator, an electrical igniter and a storage battery. The air bag generator is fixed on the inner wall of the mounting part housing, and the electric igniter is installed in the middle of the air bag generator, and the air bag generator is interconnected with the air bag through the air hole; An inertial sensor is installed on the inner wall of the right side of the mounting part housing, a battery is installed on the inner wall of the left side of the mounting part housing, and a controller is installed on the inner wall of the upper part of the mounting part housing. Preferably, the interior of the air bag generator is provided with an ignition agent, the lower part of the ignition agent is provided with a nitrogen generator, and the left and right sides of the nitrogen generator are installed with a filter. Preferably, the battery is electrically connected with an electrical igniter, an inertial sensor and a controller through a conduction line, respectively, and the controller is electrically connected with an electrical igniter and an inertial sensor.

[0010] Further, the sensor includes a spring pressure sensor of the support leg of a small manned aircraft, an inertial sensor, a water level sensor, etc. When the support leg of a small manned aircraft lands on the ground, the force sensor of the support leg spring will send the force data back to the controller. If the force data is too large for a fall, the controller will judge it as abnormal and send out the anti-fall airbag signal. When the load-bearing spring sensor of the support leg of small manned aircraft fails, the ground will impact the aircraft when falling, and the inertial sensor will play a role. Or the plane falls into the water, the plane's water level sensor will also send out the anti-fall airbag signal. Further, after receiving the sensor signal, the controller issues an electric igniter ignition command to the air bag generator, the electric igniter ignites the ignition agent, the ignition agent fires the nitrogen generator, and a large amount of nitrogen is generated into the air bag through the air hole, and the air bag is released from the lower gap under high pressure to form the air bag.

[0011] Further, the air bag is composed of nine layers of materials, from the outside to the inside, specifically anti-corrosion layer, waterproof layer, flame retardant layer, anti-puncture layer, carbon fiber layer, anti-rupture layer, base layer, sealing layer, compressive layer. The anti-corrosion layer is an epoxy resin paint with a thickness of 0.05-0.1 mm; The waterproof layer is JS waterproof coating, the thickness is 0.05-0.1 mm; The flame retardant layer is a non-toxic fireproof coating with a thickness of 0.05-0.1 mm; The anti-puncture breaking layer is polyvinylidene chloride, with a thickness of 0.3-0.5 mm; The carbon fiber layer is a carbon fiber cloth with a thickness of 0.3-0.5 mm; The anti-rupture layer is polyvinylidene chloride with a thickness of 0.3-0.5 mm; The base layer is nylon, the thickness is 0.5-0.8 mm; The sealing layer is an aerogel felt - polyurethane with a thickness of 0.1-0.2 mm; The compressive layer is a polyurethane elastomer with a thickness of 0.1-0.2 mm.

[0012] Further, the shell and the mounting part are made of carbon fiber material to reduce the overall weight of the anti-fall airbag; At the same time, the airbag is provided with a buffer structure to prevent the local force from being too large and the airbag from breaking when hitting the ground. The airbag adopts a nine-layer structure setup, especially the use of carbon fiber material with high tensile strength, which has both light weight and high strength.Advantageous Effects

[0014] Under the safety concept of "life first, people first", the invention fills the gap of safety protection for small manned aircraft and provides a choice of safety protection for small manned aircraft falling or sinking into water;

[0015] A small manned aircraft falling to the ground requires the airbag to have high strength. The airbag adopts a nine-layer structure setting, especially a carbon fiber material with high tensile strength, which has light weight and high strength; At the same time, a buffer structure is provided to prevent the local force from being too large and the air bag from breaking when the upper part hits the ground;

[0016] All shells of the invention are made of carbon fiber material, so that the anti-fall airbag has the characteristics of high temperature resistance, high strength and light weight;
