The front pressure-adjustable energy-absorbing and releasing air bag 2 is fixed together by a sealing batten 11, a plastic bag shell 12 and a non-plastic bottom plate 14 in fig. 4 through a second screw bolt 10. The non-plastic bottom plate structure is shown in figure 5 and is formed by welding or bolting a sealing bottom plate 19 and a backing plate 18, the back surface of the non-plastic bottom plate is connected with a connecting piece 17 through a third bolt 15, and the sealing bottom plate 19 is provided with a pressure-adjustable air release valve 21, an inflation pile 20 and a pressure gauge pile; the backing plate 18 is constructed as shown in fig. 6, and has a plurality of hollow holes, which facilitates the installation of the third bolts 15 and the adjustment of the pressure-adjustable air release valve 21, and simultaneously reduces the overall weight of the non-plastic base plate 14. The structural appearance of the sealing bottom plate 19 is as shown in figure 7, the sealing bottom plate has a certain radian, and reinforcing ribs are arranged on the back surface of the sealing bottom plate, so that the overall rigidity is improved; the front surface of the sealing bottom plate 19 is provided with a rib fixed with the capsule shell; the appearance of the plastic capsule shell 12 is shown in fig. 8, a transverse and longitudinal shape-limiting brace is arranged in the plastic capsule shell 12, the plastic capsule shell can be connected with a corresponding fixed edge strip on a sealing bottom plate 19 through a fourth bolt 13, and the capsule shell 12 is fixed on a non-plastic bottom plate 14 in a sealing mode through a sealing pressing strip 11. The front of the capsule shell 12 is arc-shaped. The above parts are connected with the vehicle body through a fifth bolt 16 by a connecting piece 17 fixed on a backing plate 18, the structural appearance of the connecting piece is schematically shown in figure 9, and the mounting position can be selected according to the vehicle type through the screw hole position on the backing plate 18.

The structure of the pressure-adjustable air release valve is shown in fig. 10, a mechanical pressure-adjusting device which is composed of a second spring 27, a top column 28, a pressure-adjusting wheel disc main body 29 and an eccentric circle 30 in fig. 10 is matched with a pressing block 26, a first spring 25, a piston 24 and a shell 22 to form the pressure-adjustable air release valve main body, and the pressure-adjustable air release valve main body is arranged on a sealing bottom plate 19 of front and rear pressure-adjustable energy absorption and release airbags 2 and 4 through the assembly and the matching with a fixing nut 23. The structure and appearance of the housing 22 of the pressure-adjustable bleed valve are shown in fig. 11. The pressure-adjustable air escape valve pressure regulating method is characterized in that a pressure-adjustable knob main body 29 fixed on a pressure-adjustable rotary rod 31 through a twisting pin 32 is used for rotating an eccentric circle 30 fixed on the pressure-adjustable rotary rod 31, a top column 28 installed on the pressure-adjustable knob main body 29 can be clamped into a special hemispherical groove formed in a shell 22 to be fixed when the pressure-adjustable air escape valve rotates to a specified position, at the moment, the eccentric circle 30 can press a pressing block 26 to move downwards (upwards) due to rotation, the length of a first spring 25 is adjusted, and the pressure of a piston 24 is controlled to be pressed downwards, so that the pressure regulating effect is realized.

When the front and rear pressure-adjustable energy-absorbing and releasing airbags 2 and 4 are used, gas with certain pressure intensity is stored in the front pressure-adjustable energy-absorbing and releasing airbag 2 and the rear pressure-adjustable energy-absorbing and releasing airbag 4 in advance to keep the shape of the airbags, and the pressure-adjustable air release valve 21 is used simultaneously, so that the size of the impact force transmitted to the non-plastic bottom plate 14 is selected, and the vehicle body is ensured not to deform when the internal air pressure reaches the maximum threshold value. (when driving in a low-speed city, the air pressure is lower, the air leakage pressure threshold value of the air leakage valve is adjusted to be lower, and smaller impact force is generated to pedestrians; when driving in a high-speed city, the internal pressure of the air bag is higher, the air leakage pressure threshold value of the air leakage valve is also adjusted to be higher, and the absorbed and released energy is increased). During collision, the air bag mainly deforms forwards and backwards due to the action of the transverse and longitudinal shape limiting strips, the volume of internal air is reduced, the pressure is increased, the air is released when the pressure is released, the air pressure in the air bag is kept unchanged, and the energy absorption and release effects are realized; when the air is not completely released, the energy absorption and release adjustable air bag shell 12 is pressed due to collision to increase the air pressure in the air bag, the impact force is converted into the air pressure in the air bag, and the air pressure is uniformly dispersed to the non-plastic bottom plate 14 and is uniformly transmitted to the vehicle body through the fixing piece 17. Because the front end of the capsule shell 12 transversely runs in an arc shape, a collided person (object) can be bounced away from the positive running direction of the vehicle after collision, and secondary injury is prevented.

The use method and the principle are the same as those of the front pressure-adjustable energy-absorbing and releasing air bag 2 and the rear pressure-adjustable energy-absorbing and releasing air bag 4. The size of the designed space in the hub body 33 can be changed as required, flammable components such as batteries and the like can be placed in the space, the possibility of fire caused by impact extrusion is reduced, the heat preservation effect on the batteries can be realized, and the winter driving mileage of the electric vehicle is prolonged. If the front pressure-adjustable energy-absorbing and releasing air bag 2, the rear pressure-adjustable energy-absorbing and releasing air bag 4 and the frame pressure-adjustable energy-absorbing and releasing air bag 3 are filled with non-toxic and non-combustible gas such as nitrogen, the possibility of combustion of the automobile can be reduced when collision and air leakage occur, and the fire extinguishing effect can be realized. Because the air bag has corresponding volume, the effect of increasing buoyancy is realized, the automobile floats, the vehicle and personnel are prevented from being damaged by water, and the integration of the vehicle and the ship is realized.
