Description

Technical Field

[0001] The present invention relates to the technical field of aircraft, and in particular to an aircraft fuselage safety airbag protection device. Background Art

[0002] Manned aircraft usually use multiple (such as four, eight, or even more) propellers for layout. These propellers are usually symmetrically distributed in a cross or circle to achieve stable flight and attitude control of the aircraft. By adjusting the speed of each propeller, the attitude and altitude of the aircraft can be changed. Compared with traditional single-rotor helicopters, this design does not require complex propeller angle adjustment devices, thereby simplifying the mechanical design. Due to the use of multiple propellers, this type of aircraft usually has a strong load-bearing capacity and can carry people or cargo for flight. For manned aircraft, safety is of vital importance. Although the design of multiple propellers improves the stability and load-bearing capacity of the aircraft, it also increases the failure points. Once a propeller fails, it may affect the stability and safety of the aircraft. In addition, this type of aircraft may be affected by meteorological conditions such as wind shear and turbulence during flight, resulting in unstable flight or loss of control. In order to achieve stable flight and attitude control, this type of aircraft needs to be equipped with complex flight control systems and sensors.

[0003] The airbag device of manned aircraft was first used on airplanes. Its function is to prevent pilots from being thrown out of the cockpit during high-speed flight and ensure their safety. This airbag device is also applicable to manned aircraft and can protect the lives of pilots and passengers at critical moments. When a manned aircraft collides, the airbag can be inflated quickly in a very short time (such as 30 milliseconds) to form a soft cushion to protect the driver and passengers from impact damage. This process is very fast and is completed almost in an instant, thereby effectively reducing the damage to personnel caused by the collision. However, the airbag protection device can only pop out the airbag protection inside the fuselage and cannot effectively protect the bottom of the fuselage. The protection is poor, and the driver is prone to fatigue during long-term driving, which is also one of the safety hazards. Summary of the invention

[0004] The object of the present invention is to provide an aircraft fuselage airbag protection device, which can simultaneously implement protection inside and outside the fuselage, thereby improving the protection of the device itself.

The other two ends of the first delivery pipeline are respectively communicated with the first airbags on both sides. A box body penetrates through the bottom of the body. A second airbag is fixed inside the box body. Cylindrical bodies are bolted on the four sides inside the box body. The second delivery pipeline is communicated with the cylindrical bodies. A connecting pipe is communicated with one side of the top of the cylindrical body, and the end of the connecting pipe away from the cylindrical body is communicated with the second airbag;

[0009] A closing mechanism for sealing the bottom of the box body;

[0010] A soothing mechanism that cooperates with the air pump and is used to relax the driver.

[0011] Preferably, the soothing mechanism includes an impeller, a transmission rod and a bracket. The impeller is rotatably connected to the inner wall of the connection box. One end of the transmission rod is bolted to the impeller. The bracket is bolted inside the seat body. A cross bar is also rotatably connected to the surface of the bracket. The transmission rod is rotatably connected to the bracket. A transmission column is also rotatably connected in front of the bracket. One end of the transmission column is in transmission connection with the cross bar through bevel gears. The other end of the transmission column is bolted with a turntable, and a massage block is fixed on the surface of the turntable.

[0012] Preferably, the number of the cross bars is several and they are in belt transmission connection with each other. The transmission rod and the upper transmission column are in belt transmission connection.

[0013] Preferably, the number of the massage blocks is several and they are distributed in an annular array on the surface of the turntable.

[0014] Preferably, a drain pipe is also communicated with one side of the storage box, and a second electromagnetic valve is installed on the surface of the drain pipe.

[0015] Preferably, the closing mechanism includes a baffle, a fixed sleeve and a piston. The baffle is arranged at the lower part inside the box body. There are four groups of fixed sleeves, which are fixed at the four corners of the top of the baffle. The piston is slidably connected to the inner wall of the cylinder body. One end of the cylinder body is fixed with a movable rod, and the movable rod is slidably connected to the inlet and outlet of the cylinder body. A connecting plate is bolted to the end of the movable rod away from the piston. An activity column is bolted to the other side of the connecting plate. Activity sleeves are bolted to the four corners above the inside of the box body, and the activity column is slidably connected to the inner wall of the activity sleeve. A circular plate is also bolted to the surface of the activity column. A compression spring is fixed to the side of the circular plate close to the activity sleeve, and the other end of the compression spring is fixed to the surface of the activity sleeve.

[0016] Preferably, the baffle is a lightweight plastic plate.

[0017] Preferably, the compression spring is sleeved on the surface of the activity column, and the outer diameter of the compression spring is smaller than the outer diameter of the circular plate.

[0019] Preferably, a one-way valve is also installed on the surface of the vertical pipe.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. By turning on the air pump of the present invention, external gas enters the inside of the storage box through the air delivery pipe, the connection box and the vertical pipe, so that there is high-pressure gas inside the storage box. At the same time, during the process of supplying gas to the inside, by pushing the impeller to rotate, the transmission rod and the cross bar are driven to rotate, and the transmission column is driven to rotate, so that the turntable and the massage block rotate to massage the driver's back and relieve the driver's fatigue.

[0022] 2. During the abnormal falling process of the aircraft, the first electromagnetic valve of the present invention is opened so that the gas enters the inside of the first airbag and the second airbag respectively after passing through the first delivery pipeline, the second delivery pipeline and the cylinder body, so that the first airbag and the second airbag bulge and expand, realizing protection inside and outside the fuselage at the same time, and improving the protection performance of the device.

[0023] 3. Through the setting of the baffle of the present invention, when the device is not in use, the second airbag inside the box body is protected. When supplying gas to the airbag, the piston and the movable rod are pushed by the gas to move, driving the activity column to move, so that it disengages from the inside of the fixed sleeve, and the baffle is released from fixation, thus facilitating the ejection of the second airbag.

Detailed implementation manners

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1 - 13 , an aircraft fuselage airbag protection device, including an aircraft body 1 and a seat body 2. The seat body 2 is fixed inside the aircraft body 1. The device further includes a closing mechanism 19 and a soothing mechanism 20. Boxes 3 are bolted on both sides inside the aircraft body 1. A first airbag 4 is fixed inside the box 3. An air pump 5 is bolted above the inside of the seat body 2. The outlet end of the air pump 5 is connected and provided with an air delivery pipe 6. A connection box 7 is also bolted inside the seat body 2, and the end of the air delivery pipe 6 far from the air pump 5 is communicated with the connection box 7, connecting the air pump 5 and the connection box 7 together. A vertical pipe 8 is communicated and provided at the bottom of the connection box 7. A storage tank 9 is bolted below the inside of the seat body 2. The bottom end of the vertical pipe 8 is communicated with the storage tank 9. A one-way valve 10 is also installed on the surface of the vertical pipe 8 to prevent the gas from flowing back inside the vertical pipe 8 when storing gas inside the storage tank 9. A communication pipe 11 is communicated and provided on one side of the storage tank 9. A first solenoid valve 12 is installed on the surface of the communication pipe 11. The first solenoid valve 12 is connected to the central control computer of the aircraft. The communication pipe 11 is respectively communicated and provided with a first delivery pipeline 13 and a second delivery pipeline 14. The first delivery pipeline 13 and the second delivery pipeline 14 are communicated with the communication pipe 11 through a tee joint. The other two ends of the first delivery pipeline 13 are respectively communicated with the first airbags 4 on both sides. A box body 18 penetrates through the bottom of the aircraft body 1. The bottom of the box body 18 is of an open design. A second airbag 17 is fixed inside the box body 18. Cylinders 15 are bolted on the four sides inside the box body 18. The second delivery pipeline 14 is communicated with the cylinders 15. A connecting pipe 16 is communicated and provided on one side of the top of the cylinder 15, and the end of the connecting pipe 16 far from the cylinder 15 is communicated with the second airbag 17.

[0040] The relaxation mechanism 20 includes an impeller 201, a transmission rod 202 and a bracket 203. The impeller 201 is rotatably connected to the inner wall of the connection box 7. One end of the transmission rod 202 is bolted to the impeller 201. The bracket 203 is bolted inside the seat body 2. A cross bar 204 is also rotatably connected to the surface of the bracket 203. The number of cross bars 204 is several and they are connected by belt drive between each other, so that when one group of cross bars 204 rotates, it can drive other groups of cross bars 204 to rotate together. The transmission rod 202 is rotatably connected to the bracket 203, and the transmission rod 202 is connected to the upper transmission column 205 by belt drive, so that when the transmission rod 202 rotates, it can drive the lower cross bar 204 to rotate synchronously. A transmission column 205 is also rotatably connected to the front of the bracket 203. One end of the transmission column 205 is connected to the cross bar 204 by bevel gears. The other end of the transmission column 205 is bolted with a turntable 206. Massage blocks 207 are fixed on the surface of the turntable 206. The number of massage blocks 207 is several and they are distributed in an annular array on the surface of the turntable 206. During the process of the driver using the aircraft, holes for air intake are opened on the back of the seat body 2. By turning on the air pump 5, external air enters through the inlet end of the air pump 5, and then enters the inside of the storage tank 9 through the air delivery pipe 6, the connection box 7 and the vertical pipe 8, filling the inside of the storage tank 9 with high-pressure gas, which is used to supply gas to the first airbag 4 and the second airbag 17 in case of emergency. At the same time, when the gas passes through the inside of the connection box 7, the gas can push the impeller 201 to rotate. The impeller 201 drives the transmission rod 202 to rotate. The transmission rod 202 drives the cross bar 204 to rotate through a belt. The cross bar 204 drives the transmission column 205 and the turntable 206 to rotate through bevel gears, so that the massage blocks 207 rotate to massage the back of the driver and relieve fatigue. A drain pipe 21 is also communicated with one side of the storage tank 9. A second electromagnetic valve 22 is installed on the surface of the drain pipe 21. The central control computer of the aircraft is electrically connected to the second electromagnetic valve 22. A pressure sensor 23 is also penetrated through the top of the storage tank 9. The probe end of the pressure sensor 23 is located inside the storage tank 9 to monitor the air pressure inside the storage tank 9. When the air pressure inside the storage tank 9 is too high, the second electromagnetic valve 22 is opened, allowing some of the gas inside the storage tank 9 to be discharged through the drain pipe 21 to achieve pressure relief.

[0041] The closing mechanism 19 includes a baffle 191, a fixed sleeve 192 and a piston 193. The baffle 191 is arranged at the lower part inside the box body 18. The baffle 191 is a lightweight plastic plate to make it lighter. The number of fixed sleeves 192 is four groups, which are fixed at the four corners of the top of the baffle 191. The piston 193 is slidably connected to the inner wall of the cylinder body 15. One end of the cylinder body 15 is fixed with a movable rod 194. The movable rod 194 is slidably connected to the inlet and outlet of the cylinder body 15. The end of the movable rod 194 away from the piston 193 is bolted with a connecting plate 195. The other side of the connecting plate 195 is bolted with a movable column 196. Movable sleeves 199 are bolted at the four corners above the inside of the box body 18, and the movable column 196 is slidably connected to the inner wall of the movable sleeve 199. A circular plate 198 is also bolted on the surface of the movable column 196. A compression spring 197 is fixed on the side of the circular plate 198 close to the movable sleeve 199, and the other end of the compression spring 197 is fixed to the surface of the movable sleeve 199. Under the reaction force of the compression spring 197, the circular plate 198 and the movable column 196 are subjected to a force towards the fixed sleeve 192, so that one end of the movable column 196 is inserted into the inside of the fixed sleeve 192 to fix the baffle 191, preventing the second airbag 17 at the bottom of the box body 18 from being directly exposed outside during the normal use of the aircraft and being punctured after the aircraft lands. The compression spring 197 is sleeved on the surface of the movable column 196, and the outer diameter of the compression spring 197 is smaller than the outer diameter of the circular plate 198.

[0042] When the central control computer of the aircraft detects that the aircraft is falling, it controls the first electromagnetic valve 12 to open, so that the air inside the storage tank 9 passes through the connecting pipe 11, the first delivery pipeline 13 and the second delivery pipeline 14. The gas passing through the first delivery pipeline 13 enters the inside of the first airbag 4, causing the first airbag 4 to bulge and expand. A gap groove is also opened on the surface of the box body 3 for the first airbag 4 to pop out from the inside of the box body 3. At the same time, the gas passing through the second delivery pipeline 14 enters the inside of the cylinder body 15 and pushes the piston 193 to move. Then the piston 193 drives the movable rod 194 and the connecting plate 195 to move, thereby driving the movable column 196 to move, making the movable column 196 and the circular plate 198 move away from the fixed sleeve 192 and overcoming the reaction force from the compression spring 197 to release the fixation of the baffle 191, so that the baffle 191 is separated from the fuselage of the aircraft. At the same time, the baffle 191 is made of lightweight plastic and will not cause great losses to the lower part when falling. After that, when the piston 193 passes through the end of the connecting pipe 16 connected to the cylinder body 15, the gas passes through the connecting pipe 16 and enters the inside of the second airbag 17, causing the second airbag 17 to bulge and expand, realizing protection at the bottom of the fuselage 1. Cooperating with the first airbag 4, it protects the fuselage 1 and the driver inside and outside, improving the protection performance of the device.
