[0001] The present invention relates to flying car technology, and in particular to an inflatable safety airbag for a flying car. Background Art

[0002] With the rapid development of science and technology, flying cars are gradually moving from concept to reality and becoming an important development direction in the future transportation field. However, flying cars face more complex and severe safety challenges during operation than traditional cars.

[0003] The safety protection system of traditional cars is mainly designed for ground driving scenarios and is difficult to be directly applied to flying cars. During the flight, once an emergency occurs, such as a mid-air collision or an emergency landing caused by a mechanical failure, the existing safety measures often cannot provide adequate protection for the drivers and passengers. For example, the existing seat and seat belt systems have limited protection against impact forces in high-speed flight, and it is difficult to effectively prevent the drivers and passengers from being seriously injured.

[0004] Moreover, the special operating environment of flying cars places higher demands on the performance of airbags. The inflation speed and cushioning effect of ordinary car airbags cannot meet the needs of flying cars flying at high altitudes and high speeds. At the same time, the existing safety protection devices lack targeted protection for the waist and head of the driver and passengers. Under severe impact, the waist and head of the driver and passengers are very susceptible to injury.

[0005] Therefore, developing an inflatable airbag specifically suitable for flying cars to enhance the safety protection capability of flying cars in emergency situations has become an urgent problem to be solved. Summary of the invention

[0006] Purpose of the invention: The purpose of the present invention is to provide enhanced targeted protection capabilities; another purpose of the present invention is to provide an enhanced user experience.

DETAILED DESCRIPTION

[0017] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example like Figure 1-Figure 6 As shown, an inflatable safety airbag for a flying car is provided, comprising a support plate 1, a support seat 2 is fixedly connected between two support plates 1, the outer side walls of the support seat 2 are fixedly connected with a slide rail 3, the outer side walls of the slide rail 3 are slidably connected with a self-locking slider 4, the upper surface of the self-locking slider 4 is commonly fixedly connected with a car seat 5, the outer side wall of the car seat 5 is rotatably connected with a seat back 6 through a self-locking rotating member, the inner side wall of the seat back 6 is symmetrically fixedly connected with a waist protection airbag 7, the upper part of the inner side wall of the seat back 6 is symmetrically fixedly connected with a head protection airbag 8, the outer side wall of the seat back 6 is fixedly connected with an inflation chamber 9, and the car seat 5 and the inner side wall of the seat back 6 are fixedly connected with a plurality of impact probes 14; When the vehicle sensor detects abnormal acceleration or tilt angle, the system determines that it has entered an emergency state. The central processor activates the two-stage inflation device of the inflation chamber 9 within 0.05 seconds. The first-stage high-pressure gas cylinder completes the initial inflation of the head protection airbag 8 within 0.1 seconds at a pressure of 300kPa. The head protection airbag 8 adopts a lateral deployment mode and forms an embracing protection structure through vector nozzle control. After the head protection airbag 8 is filled, the gas will enter the waist protection airbag 7. The internal pressure sensor of the waist airbag 7 adjusts the inflation volume in real time to maintain a human body contact buffer distance of 80-120mm. After the danger is eliminated, the electromagnetic exhaust valve is controlled to deflate at a rate of 5L / s, and the self-locking mechanism is automatically released. The seat assembly returns to the initial position under the action of the electric push rod. The entire reset process takes 8-12 seconds. At the same time, the system automatically completes the cylinder pressure detection and fault self-checking to prepare for the next use.

[0019] In the present embodiment, the inflation chamber 9 includes a cavity 101, a circular groove 102 is provided at the lower part of the cavity 101, a compressed gas tank 103 is connected to the circular groove 102, an inner rear surface of the circular groove 102 is fixedly connected with an air outlet groove 117, an inner side wall of the air outlet groove 117 is fixedly connected with an air outlet transverse groove 104, a top of the air outlet transverse groove 104 is fixedly connected with an air control groove 105, an inner rotational connection of a rotating column 106 is provided with a rotating block plate 107, a spring 108 is fixedly connected between the upper surface of the air block plate 107 and the air control groove 105, a waist air delivery groove 109 is symmetrically provided on the inner side wall of the air control groove 105, a ventilation vertical groove 110 is fixedly connected to the upper surface of the inner side wall of the air control groove 105, a head air delivery groove 111 is fixedly connected to the inner top of the ventilation vertical groove 110, and a waist air delivery groove 112 is fixedly connected to the waist air delivery groove 113. The inside of 109 is fixedly connected with a cylinder 112, and the outer wall of the cylinder 112 is rotatably connected with a wedge block 113 with a hole. The outer wall of the cylinder 112 is located inside the wedge block 113 with a hole and is wound with a torsion spring 114. The left end of the torsion spring 114 is fixedly connected to the inner wall of the wedge block 113 with a hole, and the right end of the torsion spring 114 is fixedly connected to the outer wall of the cylinder 112. The inner wall of the waist air delivery groove 109 is symmetrically fixedly connected with a wedge block 118, and the outer wall of the wedge block 118 is in contact with the outer wall of the wedge block 113 with a hole. The opposite ends of the waist air delivery groove 109 are fixedly connected with a head-connected air pipe 115, and the opposite ends of the head air delivery groove 111 are fixedly connected with a waist-connected air pipe 116. The head-connected air pipe 115 is fixedly connected to the adjacent head protection airbag 8, and the waist-connected air pipe 116 is fixedly connected to the adjacent waist protection airbag 7. After the collision is triggered, the high-pressure gas in the compressed gas tank 103 breaks through the sealing structure of the circular groove 102 and enters the horizontal outlet groove 104 along the outlet groove 117. At this time, the air blocking plate 107 remains in a vertical state under the pulling force of the spring 108, closing the lower channel of the air control groove 105, and forcing the gas to enter the ventilation vertical groove 110 upward. The high-pressure gas directly rushes into the head air supply groove 111 through the ventilation vertical groove 110, and quickly inflates the head protection airbag 8 through the connecting head air pipe 115. At this stage, the perforated wedge block 113 is kept at its original angle by the pre-tightening force of the torsion spring 114, and its through hole is misaligned with the waist air supply groove 109, temporarily blocking the waist air path. When the inflation pressure of the head airbag reaches the critical value, the air pressure in the air control groove 105 pushes the air blocking plate 107 to overcome the resistance of the spring 108 and rotate counterclockwise, opening the entrance of the waist air supply groove 109. When the gas rushes in, it impacts the perforated wedge block 113, causing it to rotate around the cylinder 112 until it is limited by the wedge block 118. At this time, the through hole is aligned with the waist gas delivery groove 109 to form a passage. The gas enters the waist gas delivery groove 109 through the through hole of the perforated wedge block 113, and is transported to the waist protection airbag 7 through the waist air pipe 116. The torsion spring 114 stores energy when the perforated wedge block rotates, providing a reset torque for closing the air circuit. The head and waist air circuits are sequentially controlled through mechanical interlocking, and the delay is jointly determined by the rotation resistance of the air blocking plate and the action time of the perforated wedge block. During the inflation process, the air blocking plate 107 responds to the pressure changes in the air control groove 105 in real time: when the air pressure drops, the spring 108 pulls the air blocking plate partially closed.

[0020] In this embodiment, a buckle safety belt 10 is fixedly connected to the outer wall of the car seat 5, a buckle block 11 is fixedly connected to the outer wall of the seat back 6, and a belt fixing cavity 12 is fixedly connected to the right side of the outer wall of the car seat 5; After the driver and passengers get on the car and sit down, they start the first step of safety protection. They skillfully pick up the buckled safety belt 10 fixed on the outer wall of the car seat 5, smoothly pass it through the buckle block 11 on the outer wall of the seat back 6, and then accurately insert it into the fixed belt clamping cavity 12 on the right outer wall of the car seat 5. With a crisp "click", the safety belt is firmly fixed. Once a collision occurs, the safety belt instantly changes from loose to tight. With its high-strength toughness, it is like a solid rope, tightly binding the body of the driver and passengers, greatly limiting their excessive displacement caused by inertia.

[0021] In this embodiment, a plurality of rotating grooves 15 are symmetrically formed on the inner side wall of the circular groove 102. A blocking cover 16 is connected to the inner thread of the rotating groove 15. A hand-rotating slot 17 is formed on the outer side wall of the blocking cover 16. Under normal conditions, the blocking cover 16 is tightly connected in the rotating groove 15 through the threads on the rotating groove 15, and the hand-turning slot 17 on the outer side wall thereof is convenient for manual disassembly and installation during maintenance.

[0022] In this embodiment, the inner side wall of the seat back 6 is provided with a plurality of ventilation slots 13; The inner wall of the seat back 6 is provided with a plurality of ventilation slots 13. These ventilation slots are regularly distributed and ingeniously embedded in the inner wall of the seat back 6. The design of the ventilation slots 13 is mainly to enhance the riding experience of the driver and the passenger. When the driver and the passenger sit for a long time, the part of the body in contact with the seat back 6 is prone to feel stuffy, and the ventilation slots can effectively promote air circulation.
