[0030] Secondly, the cylinder 109 is fixedly connected with the sliding base 104 and located inside the sliding base 104; the piston 111 is slidably connected with the cylinder 109 and located inside the cylinder 109; the piston rod 110 is fixedly connected with the piston 111 and located on one side of the piston 111; the two ends of the gas conveying pipe 112 are respectively communicated with the cylinder 109 and the air bag 106, and the gas conveying pipe 112 is arranged on the seat body 101; when the vehicle is hit to drive the base 103 to move, the sidewall of the base 103 drives the piston rod 110 to move, so that the piston rod 110 drives the piston 111 to move, the movement of the piston 111 pushes the air inside the cylinder 109 into the gas conveying pipe 112, and the air is injected into the air bag 106 through the gas conveying pipe 112, so that the purpose of inflating the air bag 106 is achieved.

[0031] Meanwhile, the rod body 113 is fixedly connected with the piston 111 and located on one side of the piston 111; the rubber head 114 is fixedly connected with the rod body 113 and located on the side of the rod body 113 away from the piston 111; the impact between the base 103 and the piston rod 110 is buffered by the rubber head 114, so that the piston rod 110 is prevented from being bent due to excessive impact force and the inflation of the air bag 106 is affected.

[0032] In addition, the pressure relief valve 115 is connected with and communicated with the cylinder 109 and located on one side of the cylinder 109; in order to quickly inflate the air bag 106, the air bag 106 can be fully inflated by the movement of the piston 111 with a short stroke, but if the piston 111 continues to compress the air in the cylinder 109 in the process of continuous movement of the seat body 101, the air pressure in the air bag 106 will continue to rise, and when the air pressure exceeds a certain limit, the air bag 106 may explode, causing secondary injury to the passengers; therefore, the pressure relief valve 115 is arranged, so that when the air pressure in the air bag 106 reaches a preset safety value, the pressure relief valve 115 is automatically opened, so that the gas can be discharged through the pressure relief valve 115, thereby preventing the air bag 106 from exploding.

[0033] Finally, the guide rod 116 is fixedly connected with the base 103 and slidably connected with the sliding base 104 and penetrates through the sliding base 104; the movement of the sliding base 104 and the seat body 101 is guided by the guide rod 116, so that the sliding base 104 and the seat body 101 can only move along the length direction of the guide rod 116, thereby improving the stability of the seat body 101 when moving.

[0034] When the vehicle is side-impacted, the vehicle moves and drives the base 103 to move, at this time, the slide base 104 and the seat body 101 move relative to the base 103 under the action of inertia, the base 103 extrudes the piston rod 110 to move, and drives the piston 111 to move, when the piston 111 moves in the cylinder 109, the air inside the cylinder 109 is pushed into the gas pipe 112, and the air is injected into the air bag 106 through the gas pipe 112, so that the air bag 106 expands, thereby driving the support plate 105 to extend out of the seat body 101, at this time, the passenger is supported by the support plate 105, and the impact on the passenger is buffered by the air bag 106, so as to achieve the purpose of protecting the passenger; at the same time, the impact energy is absorbed by the bumper 107, and the impact transmitted to the slide base 104 and the seat body 101 is reduced, further protecting the passenger.
