Description

Technical Field

[0001] This invention relates to the field of aircraft technology, specifically to an aircraft fuselage airbag protection device. Background Technology

[0002] Manned aircraft typically employ multiple (e.g., four, eight, or even more) propellers, usually arranged symmetrically in a cross or circular pattern, to achieve stable flight and attitude control. By adjusting the rotational speed of each propeller, the aircraft's attitude and altitude can be altered. Compared to traditional single-rotor helicopters, this design eliminates the need for complex propeller tilt adjustment mechanisms, simplifying mechanical design. Due to the multiple propellers, these aircraft typically have a high payload capacity, capable of carrying personnel or cargo. For manned aircraft, safety is paramount. While the multiple-propeller design improves stability and payload capacity, it also increases potential points of failure. A malfunction in any propeller can affect the aircraft's stability and safety. Furthermore, these aircraft are susceptible to weather conditions such as wind shear and turbulence during flight, leading to instability or loss of control. To achieve stable flight and attitude control, these aircraft require sophisticated flight control systems and sensors.

[0003] Airbag systems for manned aircraft were first used in airplanes to prevent pilots from being ejected from the cockpit during high-speed flight, ensuring their safety. This same airbag system is equally applicable to manned aircraft, protecting the lives of pilots and passengers in critical moments. In the event of a collision, the airbag inflates rapidly within a very short time (e.g., 30 milliseconds), forming a cushion to protect the pilot and passengers from impact injuries. This process is extremely rapid, almost instantaneous, effectively reducing the injury to personnel. However, airbag protection devices can only deploy from inside the fuselage, failing to provide effective protection at the bottom of the fuselage, resulting in inadequate protection. Furthermore, pilot fatigue during long flights is also a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to provide an aircraft fuselage airbag protection device that can provide protection both inside and outside the fuselage simultaneously, thereby improving the device's protective capabilities.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aircraft fuselage airbag protection device, comprising an airframe and a seat body, and further comprising:

[0006] A box is bolted to both sides inside the body. A first airbag is fixed inside the box. An air pump is bolted to the top inside the seat body. An air supply pipe is connected to the outlet end of the air pump. A connecting box is also bolted to the inside of the seat body. The end of the air supply pipe away from the air pump is connected to the connecting box.

[0007] A vertical pipe is connected to the bottom of the connecting box, and a storage box is bolted to the lower part of the seat body. The bottom end of the vertical pipe is connected to the storage box. A connecting pipe is connected to one side of the storage box, and a first solenoid valve is installed on the surface of the connecting pipe.

[0008] A first delivery pipe and a second delivery pipe are interconnected with the connecting pipe. The first delivery pipe and the second delivery pipe are interconnected with the connecting pipe through a three-way interface. The other two ends of the first delivery pipe are interconnected with the first airbags on both sides. A box is provided through the bottom of the machine body. A second airbag is fixed inside the box. Cylinders are bolted to the four sides inside the box. The second delivery pipe is interconnected with the cylinders. A connecting pipe is provided on one side of the top of the cylinder, and the end of the connecting pipe away from the cylinder is interconnected with the second airbag.

[0009] A sealing mechanism for sealing the bottom of the enclosure;

[0010] A relaxation mechanism that works in conjunction with the air pump to help the driver relax.

[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 connecting box. One end of the transmission rod is bolted to the impeller. The bracket is bolted to the inside of the seat body. A crossbar is rotatably connected to the surface of the bracket. The transmission rod is rotatably connected to the bracket. A transmission column is rotatably connected to the front of the bracket. One end of the transmission column is connected to the crossbar via a bevel gear. A turntable is bolted to the other end of the transmission column. Massage blocks are fixed to the surface of the turntable.

[0012] Preferably, there are several crossbars connected to each other via belt drive, and the drive rod is connected to the drive column above via belt drive.

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

[0014] Preferably, a pipe is also connected to one side of the storage box, and a second solenoid valve is installed on the surface of the pipe.

[0015] Preferably, the sealing mechanism includes a baffle, a fixed sleeve, and a piston. The baffle is located at the lower part of the interior of the box. There are four sets of fixed sleeves, all fixed at the four corners of the top of the baffle. The piston is slidably connected to the inner wall of the cylinder. A movable rod is fixed to one end of the cylinder and is slidably connected to the inlet and outlet of the cylinder. A connecting plate is bolted to the end of the movable rod away from the piston. A movable column is bolted to the other side of the connecting plate. Movable sleeves are bolted to the four corners of the upper interior of the box, and the movable column is slidably connected to the inner wall of the movable sleeve. A circular plate is also bolted to the surface of the movable column. A compression spring is fixed to the side of the circular plate near the movable sleeve, and the other end of the compression spring is fixed to the surface of the movable sleeve.

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

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

[0018] Preferably, the bottom of the box is an open design.

[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. This invention uses an air pump to allow external gas to enter the storage tank through the air supply pipe, connecting box, and vertical pipe, creating high-pressure gas inside the storage tank. Simultaneously, during the gas supply process, the impeller is rotated, which in turn drives the transmission rod and crossbar to rotate, and then drives the transmission column to rotate, thereby causing the turntable and massage block to rotate, massaging the driver's back and relieving driver fatigue.

[0022] 2. During the abnormal descent of the aircraft, the present invention opens the first solenoid valve, allowing gas to pass through the first and second delivery pipelines and the cylinder, and then enter the interior of the first and second airbags, thereby causing the first and second airbags to inflate and expand, providing protection both inside and outside the fuselage simultaneously, thus improving the protective performance of the device.

[0023] 3. The baffle of this invention protects the second airbag inside the box when the device is not in use. When the airbag is supplied with air, the gas pushes the piston and the movable rod to move, thereby moving the movable column to disengage it from the inside of the fixed sleeve, releasing the baffle and facilitating the ejection of the second airbag.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-13 An airbag protection device for an aircraft fuselage includes a fuselage 1 and a seat body 2. The seat body 2 is fixed inside the fuselage 1. The device also includes a sealing mechanism 19 and a relief mechanism 20. Boxes 3 are bolted to both sides inside the fuselage 1. A first airbag 4 is fixed inside the box 3. An air pump 5 is bolted to the upper part inside the seat body 2. An air supply pipe 6 is connected to the outlet end of the air pump 5. A connecting box 7 is also bolted to the inside of the seat body 2, and the end of the air supply pipe 6 away from the air pump 5 is connected to the connecting box 7, connecting the air pump 5 and the connecting box 7 together. A vertical pipe 8 is connected to the bottom of the connecting box 7. A storage tank 9 is bolted to the lower part inside the seat body 2. The bottom end of the vertical pipe 8 is connected to the storage tank 9. A one-way valve 10 is also installed on the surface of the vertical pipe 8 to prevent gas from flowing back from the vertical pipe 8 when gas is stored in the storage tank 9. A connecting pipe 11 is provided on one side of the storage box 9. A first solenoid valve 12 is installed on the surface of the connecting pipe 11. The first solenoid valve 12 is connected to the central control computer of the aircraft. A first delivery pipe 13 and a second delivery pipe 14 are respectively connected to the connecting pipe 11. The first delivery pipe 13 and the second delivery pipe 14 are connected to the connecting pipe 11 through a three-way interface. The other two ends of the first delivery pipe 13 are respectively connected to the first airbags 4 on both sides. A box 18 is provided through the bottom of the fuselage 1. The bottom of the box 18 is an open design. A second airbag 17 is fixed inside the box 18. A cylinder 15 is bolted to all four sides inside the box 18. The second delivery pipe 14 is connected to the cylinder 15. A connecting pipe 16 is provided on one side of the top of the cylinder 15, and the end of the connecting pipe 16 away from the cylinder 15 is connected to the second airbag 17.

[0040] The soothing 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 connecting box 7. One end of the transmission rod 202 is bolted to the impeller 201. The bracket 203 is bolted to the inside of the seat body 2. A crossbar 204 is rotatably connected to the surface of the bracket 203. There are several crossbars 204, which are connected to each other by belt drive, so that when one set of crossbars 204 rotates, it can drive the other sets of crossbars 204 to rotate together. The transmission rod 202 is rotatably connected to the bracket 203. The transmission rod 202 is connected to the upper... The drive column 205 is connected via belt drive, enabling the drive rod 202 to drive the lower crossbar 204 to rotate synchronously during rotation. The drive column 205 is also rotatably connected to the front of the bracket 203. One end of the drive column 205 is connected to the crossbar 204 via bevel gear drive, and the other end of the drive column 205 is bolted to a turntable 206. Massage blocks 207 are fixed to the surface of the turntable 206. Several massage blocks 207 are arranged in a circular array on the surface of the turntable 206. During the pilot's use of the aircraft, an air intake is provided on the back of the seat body 2. The air pump 5, when activated, allows outside air to enter through its inlet. The air then passes through the air supply pipe 6, connecting box 7, and vertical pipe 8 before entering the storage tank 9, filling it with high-pressure gas. This gas is used to supply air to the first airbag 4 and the second airbag 17 in emergencies. Simultaneously, as the gas passes through the connecting box 7, it drives the impeller 201 to rotate. The impeller 201 drives the transmission rod 202 to rotate, which in turn drives the crossbar 204 via a belt. The crossbar 204, through a bevel gear, drives the transmission column 205 and the turntable 206 to rotate. This causes the massage block 207 to rotate, massaging the pilot's back to relieve fatigue. A drain pipe 21 is also connected to one side of the storage box 9. A second solenoid valve 22 is installed on the surface of the drain pipe 21. The aircraft's central control computer is electrically connected to the second solenoid valve 22. A pressure sensor 23 is also installed through the top of the storage box 9. The probe end of the pressure sensor 23 is located inside the storage box 9 to monitor the air pressure inside the storage box 9. When the air pressure inside the storage box 9 is too high, the second solenoid valve 22 opens, allowing part of the gas inside the storage box 9 to be discharged through the drain pipe 21, thus achieving depressurization.

[0041] The sealing mechanism 19 includes a baffle 191, a fixing sleeve 192, and a piston 193. The baffle 191 is located at the lower part of the interior of the housing 18 and is made of lightweight plastic. Four sets of fixing sleeves 192 are fixed to the four corners of the top of the baffle 191. The piston 193 is slidably connected to the inner wall of the cylinder 15. A movable rod 194 is fixed to one end of the cylinder 15 and slidably connected to the inlet and outlet of the cylinder 15. A connecting plate 195 is bolted to the end of the movable rod 194 away from the piston 193, and a movable column 196 is bolted to the other side of the connecting plate 195. Movable sleeves 199 are bolted to the four upper corners of the interior of the housing 18, and the movable columns 196 are slidably connected to the inner walls of the movable sleeves 199. Next, a circular plate 198 is also bolted to the surface of the movable column 196. A compression spring 197 is fixed to the side of the circular plate 198 near 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 interior of the fixed sleeve 192 to fix the baffle 191. This prevents the second airbag 17 at the bottom of the box 18 from being directly exposed to the outside during 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 aircraft's central control computer detects that the aircraft is falling, it controls the opening of the first solenoid valve 12, allowing air inside the storage tank 9 to pass through the connecting pipe 11, the first delivery pipe 13, and the second delivery pipe 14. The gas passing through the first delivery pipe 13 enters the interior of the first airbag 4, causing the first airbag 4 to inflate. The surface of the box 3 also has a gap groove for the first airbag 4 to pop out from inside the box 3. At the same time, the gas passing through the second delivery pipe 14 enters the interior of the cylinder 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. The piston 193 moves away from the fixed sleeve 192, and overcomes the reaction force from the compression spring 197 to release the fixation of the baffle 191, causing the baffle 191 to detach from the aircraft fuselage. At the same time, the baffle 191 is made of lightweight plastic, so it will not cause significant damage to the area below when it falls. Afterwards, when the piston 193 passes through the end of the connecting pipe 16 connected to the cylinder 15, the gas enters the interior of the second airbag 17 through the connecting pipe 16, causing the second airbag 17 to inflate and expand, providing protection at the bottom of the fuselage 1. Together with the first airbag 4, it protects the fuselage 1 and the pilot from both inside and outside, improving the protective performance of the device.
