Description

Technical Field

[0001] The present invention relates to the technical field of aviation safety equipment, and specifically provides an aviation safety seat with multiple protections, which can be used in places such as passenger planes, helicopters, manned drones, and gliding parachutes. Background Art

[0002] With the rapid development of the aviation industry and the low-altitude economy, safety issues have attracted increasing attention. During flight, although a series of safety measures are taken, it is still difficult to completely avoid the occurrence of various sudden dangerous situations, such as plane crashes, emergency landings, mechanical failures, etc. When these dangerous situations occur, the existing aviation safety seats have certain limitations in protecting the lives of passengers.

[0003] For example, an energy-absorbing aircraft seat disclosed in Patent Application No. 201510066859.7 includes a seat, a seat support frame, and a mounting rod. The seat support frame is fixedly installed on the aircraft; it also includes a mounting rod and an energy-absorbing sheet. The energy-absorbing sheet is fixedly installed on the seat support frame, and a suspension hole is designed in the upper middle part of the energy-absorbing sheet. The mounting rod is a longitudinally extending strip structure, the seat is fixed on the mounting rod, and the top of the mounting rod is hooked in the suspension hole of the energy-absorbing sheet. The present invention uses the energy-absorbing sheet to unload, extends the travel of the seat when landing, delays the landing time of the seat, and enables the seat to land under the buffering effect, protecting the safety of the personnel on the seat. Moreover, the structure is simple, space-saving, can achieve energy absorption without additional weight, is easy to install, has a good buffering effect, and the energy-absorbing sheet is easy to replace. However, the seat belts on such safety seats may not provide sufficient protection, especially in extreme cases; for some special flight situations, such as the sideslip of a helicopter, the emergency escape of a passenger plane, the fall of a manned drone, etc., there are no targeted protection and escape measures. And before most aviation accidents occur, the crew inside the aircraft have sufficient advance notice time. When danger comes, passengers can only rely on the captain to land safely.

A downward surrounding rescue drone 9 that can automatically pop out of the seat body 1 is arranged on the back of the seat body 1. In this embodiment, the guanidine nitrate / hydrogen peroxide / sodium azide airbags 6 are distributed at the appropriate positions of the head, back, bottom, both sides and leg supports of the seat. When it is detected that the safety seat quickly drops to a certain height from the ground, the airbags quickly inflate and expand to form a buffer protection area, reducing the impact force on the passenger and protecting important parts such as the passenger's head, neck, chest, abdomen and legs. The inflation speed and inflation volume of the guanidine nitrate / hydrogen peroxide / sodium azide airbags 6 can be intelligently adjusted according to different dangerous situations to provide the best protection effect. The nylon fabric of the guanidine nitrate / hydrogen peroxide / sodium azide airbags 6 has the functions of being detachable, warm, waterproof, floating on water and having a bright color, providing a buffer time for waiting for rescue in different environments. The above-mentioned landing thrust reversers 7 are installed at the bottom of the seat. When the seat drops, the landing thrust reversers are automatically started multiple times according to the situation, generating an upward reverse thrust to slow down the descending speed of the seat and achieve a soft landing, further reducing the impact force on the passenger. And the downward surrounding rescue drone 9 is hidden at the bottom of the seat. During the seat dropping process, the drone can be automatically popped out or started in a dropping manner according to the instructions of the intelligent system and fly around the seat.

[0025] The landing reverse thrust generator 7 is installed on the seat and is automatically activated multiple times in a timely manner to generate an upward reverse thrust, achieving a soft landing; the falling-type surrounding rescue drone 9 can be automatically ejected or dropped according to the instructions of the intelligent system in case of danger, providing air rescue support, surrounding protection and rescue assistance for passengers. The various sensors in the intelligent system integration are used to monitor the flight status and environmental information of the aircraft in real time. The battery provides power support for the entire intelligent system and various protection devices. The drone flight control system controls the flight of the rescue drone. The CPU processes and analyzes the data collected by the sensors, makes decisions according to different dangerous situations, and controls the activation and operation of each protection device.

[0026] Furthermore, an emergency oxygen supply mask 10 is also provided inside the seat body 1.

[0027] Furthermore, an emergency kit 11 is placed at the bottom of the seat body 1.

[0028] Furthermore, the landing reverse thrust generator 7 is automatically activated multiple times in a timely manner on the seat body 1 to generate an upward reverse thrust, achieving a soft landing.

[0029] Furthermore, the five-point seat belt 2 is made of high-strength, wear-resistant and fireproof materials, and has good flexibility and tensile strength.

[0030] Furthermore, there are a total of three parachutes 5, which are evenly distributed on the back and both sides of the seat body 1. The parachute controller 14 in each parachute 5 is electrically connected to the CPU 411. The three parachutes 5 are evenly distributed on the back and both sides of the seat body 1. Adopting advanced burst parachute technology, it has the characteristics of quickly deploying the parachute and the three parachutes opening simultaneously for a stable and comfortable landing. The parachute controller 14 is connected to the CPU 411. When the CPU 411 determines that the safety seat body 1 is in an emergency descent, it can automatically trigger the release of the parachute. Through the comprehensive judgment of the captain and the computer, when the accident is inevitable, the passengers can land safely before the plane crashes; and a parallel device mechanism 412 is built into the parachute 5 and is connected to the CPU 411. Through the seat body 1 safety system's parachute rope retracting device, the influence of the parallel wind and air flow on the seat body 1 is reduced to keep the parachute stable.

[0031] Furthermore, a spare parachute 12 is also provided inside the seat body 1, and the spare parachute controller 13 in the spare parachute 12 is electrically connected to the CPU 411. The added spare parachute 12 serves as an additional safety guarantee and is installed at an appropriate position on the seat body 1. In the case where the parachute 5 fails or cannot be deployed normally, the spare parachute 12 can be activated manually or automatically to ensure that the passengers still have a chance to escape.

[0032] Furthermore, the five-point safety belt 2 can automatically tighten when a dangerous situation is detected to fix the passenger on the seat body 1, and monitor the status of the safety belt in real time and feed back relevant information to the CPU 411.

[0033] Furthermore, the parachute 5 and the reserve parachute 12 can be automatically or manually released when the deployment conditions are met to ensure the safe landing of the passengers.

[0034] Furthermore, the guanidine nitrate / hydrogen peroxide / sodium azide airbag 6 can be rapidly inflated and deployed to form a buffer protection area when a severe collision or emergency landing of the aircraft is detected, and the CPU 411 can automatically adjust the inflation speed and inflation volume according to different dangerous situations.

[0035] The methods for escaping from different aircrafts in case of danger of the seat disclosed by the present invention are as follows: Passenger aircraft: The tail escape method is adopted. In case of emergency, the seat moves to the tail of the aircraft through the sliding track, and then safely leaves the aircraft through the tail, avoiding the danger of passengers being violently hit by the front and middle of the aircraft, being sucked into the engine, etc.

[0036] Manned UAV: ​​Use the falling escape method. When a manned UAV fails, the seat is separated from the main body of the UAV and falls safely to the ground through devices such as parachutes and landing reverse thrust generators.

[0037] Helicopter: Side-slide escape is adopted. When the helicopter is in danger, the seat slides to the side of the helicopter through a special mechanism and separates from the main body of the helicopter to avoid direct impact when the helicopter crashes.

[0038] Emergency kit: The list of items in the emergency kit can be customized according to different emergency scenarios and needs, with self-locking protection and necessary protective life-saving equipment, aiming to provide users with safety protection in scenarios such as health, escape, and emergency rescue.

[0039] High-altitude emergency oxygen mask: used at altitudes above 4,000 meters. When the aircraft is in distress at this altitude, passengers will wear oxygen masks before sliding out of the aircraft to supply oxygen to the passengers, preventing them from suffering from hypoxia, dizziness, or even loss of consciousness.

[0040] Spring hydraulic buffer device: Adding a spring hydraulic buffer device to the safety seat can better cushion the impact of falling to the ground and increase the safety and comfort of the personnel.

[0041] In this embodiment, the seat is manufactured and installed as follows: The frame and shell of the seat are made of high-strength and lightweight aviation materials to ensure that the seat can maintain structural integrity when subjected to large impact forces. High-quality leather and filling cotton are used to ensure the comfort of the seat. Each component is installed on the seat body 1 according to the design requirements, and strict debugging and testing are carried out to ensure that the performance of each component meets the requirements; the various sensors, batteries, CPU and other components of the seat intelligent control system 4 are integrated inside the seat, and through reasonable wiring and interface connections, information interaction and collaborative work between the components are realized; after the installation is completed, the intelligent system is set and calibrated. According to the characteristics and flight parameters of different aircraft, the various parameters of the intelligent system are set, such as the deployment height and speed threshold of the parachute, the inflation conditions of the airbag, the starting height of the landing reverse thrust generator, etc.; the sensor is calibrated to ensure the accuracy and reliability of its measurement data. By simulating various dangerous situations, the decision-making and control functions of the intelligent system are tested and optimized so that it can respond quickly and accurately in practical applications.

[0042] The working principle of the device of the present invention under different dangerous situations is as follows: 1. Aircraft (passenger plane) crash: When the aircraft is in an emergency state that cannot be avoided, the 5-point seat belts will be automatically tightened first to fix the passengers in the seats. If the danger occurs at an altitude of more than 4,000 meters, the emergency oxygen mask must be put on first. Then, the seat will automatically slide out of the aircraft, and the three parachutes on the seat will then automatically deploy, allowing the seat and passengers to slowly descend. At the same time, the airbags will be inflated and deployed at a certain height to provide cushioning protection for the passengers. The landing reverse thrust generator will be activated multiple times in a timely manner to further slow down the descent speed and provide protection for a soft landing. If the main parachute fails, the backup parachute will be automatically activated. During the whole process, the pop-up surround rescue drone will automatically fall or pop up into the air, send a distress signal and guide the rescuers, and multiple measures will ensure the safe landing of the passengers.

[0043] 2. Failure of manned drones: When a manned drone fails, the intelligent system controls the seat to separate from the drone body, and the seat falls safely to the ground through a parachute and landing reverse thrust generator. The falling surround rescue drone flies around the passenger to provide necessary rescue assistance.

[0044] 3. Dangerous situations of helicopters: When the helicopter is in danger, the seats will be separated from the main body of the helicopter by sliding sideways. During the sliding process, the seat belts and airbags will protect the passengers. After separation, the parachute will be deployed and the landing reverse thrust generator will be activated multiple times in a timely manner to ensure a safe and soft landing for the passengers.

[0045] 4. Gliding parachute sports event: The safety seat is separated from the aircraft or drone body. The seat is opened by a parachute, and the falling / pop-up surrounding drone flies around the parachute for shooting. The airbag and landing counter-thrust generator safely descend to the ground, and a process video is generated with one key to safely complete the gliding landing movement. The airbag can quickly inflate and deploy when it detects a severe impact or emergency landing of the aircraft, forming a buffer protection area, and the inflation speed and inflation volume can be intelligently adjusted according to different dangerous situations.

[0046] The advantages of the present invention are as follows: 1. The present invention integrates a variety of advanced protection devices and intelligent systems, which can provide comprehensive and reliable protection for passengers in various dangerous situations, greatly improving the safety of air flight.

[0047] 2. For different types of aircraft and dangerous situations, corresponding escape methods and protection measures are designed, which have strong pertinence and adaptability and can better meet the requirements of aviation safety.

[0048] 3. The integration of the intelligent system enables the seat to monitor the flight status and environmental information in real time, make autonomous decisions and activate the corresponding protection devices, improving the reaction speed and protection effect, and providing passengers with one more option when an accident occurs.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
