When the connecting belt 6 is pulled, only one side of the connecting belt 6 needs to be pulled. Under the transmission of the gear 10, both shafts 4 can be rotated, so that the connecting belt 6 on the other side can be released from the outside of the shaft 4. By using the clamping joint 9 and the clamping box 8, the installation box 2 can be bound and installed on the seat, which is convenient for disassembly and installation. The inflatable air cushion 1 can provide impact protection for the human body. A micro air pump 12 is fixedly installed on the rear surface of the inflatable air cushion 1, which is located inside the mounting box 2. The output end of the micro air pump 12 is connected to the inside of the inflatable air cushion 1. The micro air pump 12 is electrically connected to the flying car intelligent controller. When the car is impacted, the micro air pump 12 is automatically started to control the inflatable air cushion 1 to inflate rapidly.

A spring 43 is fixedly connected between the control box 30 and the lifting plate 32, and a toggle block 44 is fixedly connected to the front surface of the lifting plate 32 located inside the toggle slot 31; The exhaust hole 27 is connected to the inside of the inflatable air cushion 1. Under normal conditions, the docking hole 29 and the exhaust hole 27 are in a misaligned state. When the flying car is impacted, the micro air pump 12 starts to inflate, which can expand the inflatable air cushion 1, wrap the human body, and protect the human body. After the protection is completed, the rack 33 can be driven to move by pressing the toggle block 44, and the multiple toothed discs 28 can be rotated at the same time, so that the docking hole 29 is connected to the exhaust hole 27. At this time, under the pull of the spring 25, the inflatable airbag 1 is reset, and the gas is discharged from the docking hole 29, which is convenient for the human body to detach from the inflatable air cushion, and avoids the human body being unable to detach from the inflatable air cushion 1 in time after the inflatable air cushion 1 is inflated to protect the human body.
