Therefore, it cannot be understood as a limitation on the embodiments of the present application.

[0046] Most of the current amphibious vehicles are to improve the sealing of ordinary vehicles to enable them to act as a hull, and then the scheme of driving in water is to increase the propeller and its drive in the car. For example, the prior art increases the buoyancy of the vehicle in water by adding an air bag to the land vehicle, including a buoyancy air bag, a device for fixing the air bag, a pipeline connected with the air bag, a gas source device, a gas pressure detection and control device, a power and power driving device, and an auxiliary balance detection and control system.

[0047] However, these schemes are only a simple combination of the driving method of a ship and an ordinary vehicle. If a single propeller is used for propulsion, a drive is needed to change the direction of the propeller propulsion to make it turn. If multiple propellers are used for propulsion, multiple drives are also needed. Moreover, it is difficult to make the propeller blades and driving force large. In summary, the current scheme has a series of problems such as complex structure, increased vehicle weight, high cost, and small thrust.

Since the movable blade 3 can at least partially cover the opening of the groove 221 and the movable blade 3 can be rotationally connected with the spoke 22, the air bag 4 located in the groove 221 can be in contact with the movable blade 3, and the air bag 4 with increased volume can exert a pushing force on the movable blade 3, so that the movable blade 3 can rotate relative to the spoke 22, that is, the movable blade 3 can be in an inactive state when the air bag 4 is not inflated, and the movable blade 3 can be opened and in a working state after the air bag 4 is inflated. Since the valve 7 can be used to open and close the gas inlet pipe 5 and the gas outlet pipe 6, the valve 7 can determine whether the movable blade 3 is in a working state. Through the above design, the movable blade 3 required when the vehicle drives in water can be integrated on the rim assembly 1 provided by the vehicle, the structure of the rim assembly 1 used to push the vehicle to drive in water can be simplified, the weight of the whole vehicle can be reduced, and the cost can be reduced.

When the air bag 4 is injected with gas, the movable blade 3 can be opened by the air bag 4 with increased volume, and the opened movable blade 3 can rotate around the rotating shaft 225, thereby the movable blade 3 can form a certain opening angle relative to the spoke 22, which can provide favorable conditions for the self-rescue of the vehicle under water.

[0055] Referring to Figure 5In a possible implementation, the second support 223 and the fixing seat 222 can be respectively located on the side of the spoke 22 provided with the groove 221, and the second support 223, the groove 221 and the fixing seat 222 can be sequentially arranged, that is, the opposite sides of the side of the spoke 22 facing the movable vane 3 can be respectively provided with the second support 223 and the fixing seat 222, and the groove 221 can be located between the second support 223 and the fixing seat 222.

Specifically, one end of the rope may be located on the side of the spoke 22 facing the movable blade 3, and the other end of the rope may be located on the side of the movable blade 3 facing the spoke 22. This allows the movable blade 3 to be restrained by the stretched rope after being expanded by the inflated airbag 4 and rotating a certain angle about the rotation axis 225. The maximum opening and closing angle can be changed by adjusting the length of the rope and the relative positions of the two ends of the rope to the movable blade 3 and the spoke 22.

[0060] In one possible embodiment, the number of movable blades 3 may be at least two, the number of airbags 4 may be at least two, and the movable blades 3 and airbags 4 may be arranged one-to-one. By providing at least two movable blades 3 and at least two airbags 4, and by providing a one-to-one arrangement of movable blades 3 and airbags 4, after a vehicle falls into water, at least two movable blades 3 can be inflated by the one-to-one arrangement of inflated airbags 4, and together provide driving force for the vehicle to move underwater, thereby enhancing the underwater driving force of the vehicle and facilitating the vehicle's self-rescue underwater.

[0061] Figure 7 This is a structural diagram of the rim assembly 1 from another perspective of the embodiment of the present application. Figure 7 、 Figure 3 and Figure 5 As shown, in a possible embodiment, the at least two airbags 4 may include a first airbag 41 and a second airbag 42. The first airbag 41 may be connected to the air inlet pipe 5 and the air outlet pipe 6 through the through hole 2213. The rim assembly 1 may further include a connecting pipe 82. The inner wall of the groove 221 corresponding to the first airbag 41 is provided with an air hole 2212. The first airbag 41 may be connected to the connecting pipe 82 through the air hole 2212. The connecting pipe 82 may be connected to the second airbag 42. This allows the air inlet pipe 5 to inject gas into the first airbag 41 through the through hole 2213. The fluid in the airbag 41 can be synchronously injected into the second airbag 42 through the connecting tube 82; when the air outlet pipe 6 discharges the gas in the first airbag 41 through the through hole 2213, the gas in the second airbag 42 can be synchronously discharged through the connecting tube 82 and the air outlet pipe 6, which makes the air pressure of the first airbag 41 and the second airbag 42 increase or decrease synchronously, and the air pressure of all the airbags 4 can be equal, that is, the opening and closing angles of all the movable blades 3 relative to the spokes 22 can be equal, so that all the movable blades 3 can provide uniform driving force for the vehicle, which is beneficial to the self-rescue of the vehicle underwater.

[0062] In a possible implementation, the communication pipe 82 can be part of the communication member 8, the communication member 8 can further include a communication ring 81, and the communication pipe 82 can be provided on the communication ring 81. The communication pipe 82 can be in communication with the communication ring 81, and any two communication pipes 82 can be in communication through the communication ring 81, that is, the gas in any two communication pipes 82 can be transmitted to each other through the communication ring 81.

[0063] Figure 9 is a structural schematic diagram of the rim assembly 1 when the movable blade 3 is working. As shown in Figure 9 and Figure 3 In a possible implementation, the rim assembly 1 can further include a controller 9, and the controller 9 can be arranged on the outer wall of the rim body 21. The controller 9 can be used to control the valve 7 to open and close the air inlet pipe 5 and the air outlet pipe 6. By arranging the controller 9 in the rim assembly 1, and arranging the controller 9 on the outer wall of the rim body 21, the controller 9 can control the valve 7 to open and close the air inlet pipe 5 and the air outlet pipe 6, so that the valve 7 can be quickly controlled by the controller 9 receiving the command, and the air inlet pipe 5 and the air outlet pipe 6 can be quickly opened and closed, so that the air bag 4 can quickly expand the movable blade 3 and adjust the opening and closing angle of the movable blade 3 relative to the spoke 22, which is beneficial to the self-rescue of the vehicle under water.

[0064] As shown in Figure 4 and Figure 7 In a possible implementation, the rim body 21 can include an air valve 212, and the controller 9 and the air valve 212 can be symmetrically arranged on opposite sides of the rim body 21, that is, the controller 9 and the air valve 212 can be symmetrically distributed on the rim 2, which can make the gravity of the rim 2 uniformly distributed, that is, the center of gravity of the rim 2 can be close to the geometric center of the rim 2, which is beneficial to the dynamic balance of the rim 2. In addition, the rim body 21 can further include an air pipe 211, the air pipe 211 can penetrate the recess inner wall 2211 of the recess 221 on the spoke 22 and be in communication with the through hole 2213 on the recess inner wall 2211, that is, one end of the air pipe 211 can be in communication with the air bag 4. The other end of the air pipe 211 away from the air bag 4 can be in communication with the valve 7, the gas flowing through the air inlet pipe 5 and the valve 7 can be injected into the air bag 4 through the air pipe 211, and the gas in the air bag 4 can flow through the valve 7 and the air outlet pipe 6 and be discharged.

[0065] The detailed structure of the rim assembly 1 of the present application is introduced above, and the schematic structure diagram of the rim assembly 1 of the present application assembled on the vehicle will be described in detail below.

[0066] Figure 10 is a structural schematic diagram of the vehicle 10 provided by the embodiment of the present application. Referring to Figure 10, the vehicle 10 can include a vehicle body 11, a driving member (not shown in the figure), a tire 12, a hub 13 and a wheel rim assembly 1, the wheel rim assembly 1 can be connected to the vehicle body 11 through the hub 13, the driving member can drive the hub 13 to rotate, and the tire 12 can be fitted on the wheel rim 2; the tire 12 can have a gas outlet hole, the gas outlet hole can be in communication with the gas inlet pipe 5 and the inner cavity of the tire 12, and the gas outlet pipe 6 can be in communication with the outside of the tire 12, i.e., with the outside world.

[0067] By arranging the vehicle body 11, the driving member, the tire 12, the hub 13 and the wheel rim assembly 1 in the vehicle 10, the driving member can drive the hub 13 to drive the tire 12 and the wheel rim 2 to rotate, when the valve 7 opens the gas inlet pipe 5, the gas in the tire 12 can enter the air bag 4 through the gas outlet hole, the gas inlet pipe 5 and the through hole 2213 in sequence, so that the air bag 4 can open the movable vane 3 and increase the opening and closing angle of the movable vane 3 relative to the spoke 22, when the valve 7 opens the gas outlet pipe 6, the gas in the air bag 4 can be discharged to the outside of the tire 12 through the through hole 2213 and the gas outlet pipe 6 in sequence, so that the air bag 4 with reduced volume can reduce the opening and closing angle of the movable vane 3 relative to the spoke 22, and finally the vehicle 10 can realize self-rescue after falling into water.

[0068] The schematic structure of the vehicle 10 of the present application is introduced above, and a vehicle 10 control method proposed by the present application will be described in detail below.

[0069] Figure 11 is a flowchart of the vehicle 10 control method provided by the embodiment of the present application Figure 1 . Referring to Figure 11 , the vehicle 10 control method can include:

[0070] Step S100: receiving an inflation signal;

[0071] Step S200: controlling the valve to open the gas inlet pipe and close the gas outlet pipe.

[0072] The steps of the vehicle 10 control method of the present embodiment can be as follows: receiving an inflation signal, controlling the valve 7 to open the gas inlet pipe 5, so that the tire 12 can inflate the air bag 4, and closing the gas outlet pipe 6 to limit the air bag 4 to discharge gas outward, so that when the valve 7 opens the gas inlet pipe 5, the gas in the tire 12 can enter the air bag 4 through the gas outlet hole, the gas inlet pipe 5 and the through hole 2213 in sequence, so that the air bag 4 can open the movable vane 3, and as the air pressure of the air bag 4 increases, the air bag 4 can increase the working opening and closing angle of the movable vane 3 under the resistance of the outside world, such as water, so that the movable vane 3 following the rotation of the vehicle wheel can provide the required driving force for the vehicle 10 under water, and finally the self-rescue of the vehicle 10 after falling into water can be realized.

[0073] It should be noted that when there is no external force acting on the movable blades 3, for example, when the vehicle 10 is traveling on land, the movable blades 3 are expanded by the airbag 4, that is, the connection between the connecting member 31 and the fixing seat 222 is cancelled, for example, the buckle 311 may be pushed away from the slot 2221, and the different air pressures of the airbag 4 will basically have no effect on the opening and closing angles of the movable blades 3. At this time, the opening and closing angles of the movable blades 3 may have a maximum value, and the opening and closing angle corresponding to the maximum value may be referred to as a full opening and closing angle; when the movable blades 3 are subjected to external force, for example, when the vehicle 10 is moving in water, the movable blades 3 may be expanded by the airbag 4 and may be driven as a propeller. At this time, due to the resistance of water, the higher the air pressure of the airbag 4 at the same speed, the larger the opening and closing angle of the movable blades 3 may be. The opening and closing angle of the movable blades 3 when driven underwater may be referred to as a working opening and closing angle, and the maximum value of the working opening and closing angle is always smaller than the full opening and closing angle. When the vehicle 10 moves in the water, the working opening and closing angle of the movable blade 3 can be changed in two ways. One is to control the time when the valve 7 opens the air inlet pipe 5, that is, to control the total air intake of the airbag 4, thereby increasing the air pressure of the airbag 4 from the initial pressure value to the tire pressure value of the tire 12; the other is to control the valve 7 to open the air outlet pipe 6 to discharge the gas from the airbag 4 when the air pressure of the airbag 4 exceeds the required value.

[0074] Figure 12 This is a flow chart of the vehicle 10 control method provided in the embodiment of the present application. Figure 2 See also Figure 12 In one possible implementation, the vehicle 10 control method may include:

[0075] Step S100: receiving an inflation signal;

[0076] Step S200: Control the valve to open the air inlet pipe and close the air outlet pipe;

[0077] Step S300: receiving an exhaust signal;

[0078] Step S400: Control the valve to open the air outlet pipe and close the air inlet pipe.

[0079] The steps of the vehicle 10 control method of the embodiment can be as follows: receiving an inflation signal, controlling the valve 7 to open the air inlet pipe 5 so that the tire 12 can inflate the air bag 4, and closing the air outlet pipe 6 to limit the air bag 4 to exhaust outward, so that the movable blade 3 can reach the working opening and closing angle required for the underwater driving of the vehicle 10. Then receive the exhaust signal, control the valve 7 to open the air outlet pipe 6, so that the air bag 4 can exhaust outward, and close the air inlet pipe 5 to isolate the cavity in the tire 12 and the air bag 4. By adding the steps of controlling the valve 7 to open the air outlet pipe 6 and close the air inlet pipe 5 after the steps of opening the air inlet pipe 5 and closing the air outlet pipe 6, the cavity in the tire 12 and the air bag 4 can be isolated, and the gas in the air bag 4 can be sequentially discharged to the outside of the tire 12 through the through hole 2213 and the air outlet pipe 6, so that the air bag 4 with reduced volume can reduce the working opening and closing angle of the movable blade 3 under the resistance of water, and then the relative force of the rotating movable blade 3 and the water can be adjusted, which can be beneficial to the self-rescue of the vehicle 10 after falling into the water.

[0080] Figure 13 is a flowchart of the vehicle 10 control method provided by the embodiment of the application Figure 3 . Referring to Figure 13 , in a possible implementation, the vehicle 10 control method can include:

[0081] Step S100: receiving an inflation signal;

[0082] Step S200: controlling the valve to open the air inlet pipe and close the air outlet pipe;

[0083] Step S500: receiving a closing signal;

[0084] Step S600: controlling the valve to close the air inlet pipe.

[0085] The steps of the vehicle 10 control method of the embodiment can be as follows: receiving an inflation signal, controlling the valve 7 to open the air inlet pipe 5 so that the tire 12 can inflate the air bag 4, and closing the air outlet pipe 6 to limit the air bag 4 to exhaust outward, so that the movable blade 3 can reach the working opening and closing angle required for the underwater driving of the vehicle 10. Then receive the exhaust signal, control the valve 7 to open the air outlet pipe 6, so that the air bag 4 can exhaust outward, and close the air inlet pipe 5 to isolate the cavity in the tire 12 and the air bag 4. By adding the steps of controlling the valve 7 to open the air outlet pipe 6 and close the air inlet pipe 5 after the steps of opening the air inlet pipe 5 and closing the air outlet pipe 6, the cavity in the tire 12 and the air bag 4 can be isolated, and the gas in the air bag 4 can be sequentially discharged to the outside of the tire 12 through the through hole 2213 and the air outlet pipe 6, so that the air bag 4 with reduced volume can reduce the working opening and closing angle of the movable blade 3 under the resistance of water, and then the relative force of the rotating movable blade 3 and the water can be adjusted, which can be beneficial to the self-rescue of the vehicle 10 after falling into the water.

[0086] Figure 14 is a flowchart of a vehicle 10 control method provided by an embodiment of the present application Figure 4 . Referring to Figure 14 In a possible implementation, the vehicle 10 control method can include:

[0087] Step S100: receiving an inflation signal;

[0088] Step S200: controlling the valve to open the intake pipe and close the exhaust pipe;

[0089] Step S300: receiving an exhaust signal;

[0090] Step S400: controlling the valve to open the exhaust pipe and close the intake pipe;

[0091] Step S500: receiving a closure signal;

[0092] Step S600: controlling the valve to close the intake pipe.

[0093] The steps of the vehicle 10 control method of the present embodiment can be as follows: receiving an inflation signal, controlling the valve 7 to open the intake pipe 5 so that the tire 12 can inflate the air bag 4, and closing the exhaust pipe 6 to limit the air bag 4 to exhaust outward, so that the movable blade 3 can reach the working opening and closing angle required for the vehicle 10 to drive underwater. Then receive an exhaust signal, control the valve 7 to open the exhaust pipe 6, so that the air bag 4 can exhaust outward, and close the intake pipe 5 to isolate the cavity inside the tire 12 and the air bag 4, so that the gas in the air bag 4 can be sequentially discharged to the outside of the tire 12 through the through hole 2213 and the exhaust pipe 6, so that the air bag 4 with reduced volume can reduce the working opening and closing angle of the movable blade 3 under the resistance of water, and then the relative force of the rotating movable blade 3 and the water can be adjusted. Then receive a closure signal, control the valve 7 to close the intake pipe 5 to isolate the cavity inside the tire 12 and the air bag 4. By adding the step of controlling the valve 7 to close the exhaust pipe 6 after the step of opening the exhaust pipe 6 and closing the intake pipe 5, the air bag 4 can be isolated from the cavity inside the tire 12 and the outside, so that the air pressure of the air bag 4 can be maintained unchanged, so that the working opening and closing angle of the movable blade 3 relative to the spoke 22 under the resistance of water can be fixed, which can be beneficial to the self-rescue of the vehicle 10 after falling into the water.

[0094] Figure 15 is a flowchart of a vehicle 10 control method provided by an embodiment of the present application Figure 5 . Referring to Figure 15 In a possible implementation, the vehicle 10 control method can include:

[0095] Step S100: receiving an inflation signal;

[0096] Step S200: Control the valve to open the air inlet pipe and close the air outlet pipe;

[0097] Step S210: receiving tire pressure values;

[0098] Step S220: Determine whether the tire pressure value is less than or equal to a threshold value. If yes, execute step S230; if no, execute step S210 again.

[0099] Step S230: Control the valve to close the air intake pipe.

[0100] The control method for vehicle 10 of this embodiment may proceed as follows: receiving an inflation signal, controlling valve 7 to open air inlet pipe 5, allowing tire 12 to inflate air into airbag 4, and closing air outlet pipe 6 to restrict airbag 4 from exhausting air outward, allowing movable blades 3 to reach the required operating opening and closing angle for underwater driving of vehicle 10. Subsequently, the tire pressure of tire 12 may be received, and a determination may be made as to whether the tire pressure is less than a threshold value, the threshold being the minimum tire pressure value at which tire 12 can maintain normal wheel rotation. If the tire pressure is less than the threshold value, valve 7 may be controlled to close air inlet pipe 5. If the tire pressure is greater than the threshold value, the open state of air inlet pipe 5 and the closed state of air outlet pipe 6 may be maintained, and step S210 and subsequent step S220 may be executed again to repeat the determination. After opening the air intake pipe 5 and closing the air outlet pipe 6, by receiving the tire pressure value of the tire 12 and determining that the tire pressure value is lower than the threshold value, the valve 7 can be controlled to close the air intake pipe 5, so that the gas in the tire 12 will not be injected into the airbag 4 without restriction, that is, the tire pressure value of the tire 12 can have a lower limit, which is the lowest tire pressure value that can maintain normal rotation of the wheel. This can be beneficial to self-rescue after the vehicle 10 falls into the water.

[0101] Figure 16 This is a flow chart of the vehicle 10 control method provided in the embodiment of the present application. Figure 6 See also Figure 16 In one possible implementation, the vehicle 10 control method may include:

[0102] Step S100: receiving an inflation signal;

[0103] Step S200: Control the valve to open the air inlet pipe and close the air outlet pipe;

[0104] Step S210: receiving tire pressure values;

[0105] Step S220: Determine whether the tire pressure value is less than or equal to a threshold value. If yes, go to step S230; if no, go to step S500.

[0106] Step S230: Control the valve to close the air intake pipe;

[0107] Step S500: receiving a closing signal;

[0108] Step S600: controlling the valve to close the air inlet pipe.

[0109] The steps of the vehicle 10 control method of the present embodiment can be as follows: receiving an inflating signal, controlling the valve 7 to open the air inlet pipe 5 so that the tire 12 can inflate the air bag 4, and controlling the valve 7 to close the air outlet pipe 6 to limit the air bag 4 from discharging air to the outside, so that the movable vane 3 can reach the working opening and closing angle required for the vehicle 10 to drive underwater. Then the tire pressure value of the tire 12 can be received, and it is determined whether the tire pressure value is less than a threshold value, which is the minimum tire pressure value that the tire 12 can maintain normal rotation of the wheel, if the tire pressure value is less than the threshold value, the valve 7 can be controlled to close the air inlet pipe 5, if the tire pressure value is greater than the threshold value, the state of the air inlet pipe 5 being open and the air outlet pipe 6 being closed can be maintained unchanged; after waiting for a period of time, step S500 and the subsequent step S600 can be continued to be executed, that is, receiving a closing signal from the signal chamber, and controlling the valve 7 to close the air inlet pipe 5 to isolate the cavity in the tire 12 and the air bag 4. By adding the step of controlling the valve 7 to close the air outlet pipe 6 after the step of opening the air outlet pipe 6 and closing the air inlet pipe 5, the air bag 4 can be isolated from the cavity in the tire 12 and the outside, and the air pressure of the air bag 4 can be maintained unchanged, so that the working opening and closing angle of the movable vane 3 relative to the spoke 22 can be fixed, which can be beneficial to the self-rescue of the vehicle 10 after falling into water. The vehicle 10 control method is described in detail above, and the self-rescue principle of the vehicle falling into water will be described in detail below with reference to the accompanying drawings.

[0110] Figure 17 is a schematic view of the cooperation structure of the rim assembly 1 and the vehicle body 11 of the present embodiment. Referring to Figure 17 , the vehicle body 11 can include a vehicle frame 111, a steering gear 112, a suspension swing arm 113, and a steering knuckle 114. The vehicle frame 111 can have sufficient strength and rigidity to bear the load of the vehicle 10 and the impact from the wheels. The vehicle frame 111 can support and connect various assemblies of the vehicle, maintain the relative correct positions of the assemblies, and bear various loads inside and outside the vehicle 10. The steering gear 112 can be arranged on the vehicle frame 111, and the steering gear 112 can appropriately transform the steering torque and the steering angle from the steering wheel, that is, decelerate and increase the torque, and then output the steering torque and the steering angle to the steering link mechanism, so as to make the vehicle 10 turn. Illustratively, the steering gear 112 can be a rack-and-pinion type, a recirculating ball type, a worm-and-crank-pin type, a power steering gear, etc. The suspension swing arm 113 can be connected with the wheel through the steering knuckle 114, and in combination with Figure 10 and Figure 16 , the wheel can include the rim assembly 1, the tire 12, and the hub 13, and the suspension swing arm 113 can ensure the stability of the wheel during the driving of the vehicle 10.

[0111] Figure 18 is a schematic diagram of the working principle of the movable vane 3 of the embodiment of the present application. Referring to Figure 18 When the wheel rim 2 rotates counterclockwise, the movable vane 3 can rotate with it, and since the movable vane 3 can be pried open by the inflated air bag 4, the movable vane 3 can form a certain opening angle with respect to the spoke 22, so that the contact area of the rotating movable vane 3 with air or liquid can be increased, which can make the air or liquid flow from the inside of the wheel rim 2 to the outside of the wheel rim 2. When the wheel rim 2 rotates clockwise, the rotation of the movable vane 3 can make the air or liquid flow from the outside of the wheel rim to the inside of the wheel rim. Similarly, the movable vane 3 can be designed reversely, i.e., the positions of the second support 223 and the fixed seat 222 on the spoke can be transposed, and the position of the connecting piece 31 on the movable vane 3 can be changed accordingly, so that when the wheel rim 2 rotates clockwise, the air or liquid can flow from the inside of the wheel rim to the outside of the wheel rim; and when the wheel rim 2 rotates counterclockwise, the air or liquid can flow from the outside of the wheel rim to the inside of the wheel rim.

[0112] Figure 19 is a schematic diagram of the underwater self-rescue of the vehicle 10 of the embodiment of the present application. In combination with Figure 19 , Figure 10 and Figure 18 , under the perspective plane shown in Figure 19 , the top view of the vehicle 10 when driving straight to the right front in water is shown in Figure 19 , at this time, the front axle wheel rim assembly 1 can be offset to the left with respect to the vehicle body 11 and rotate clockwise, the right front wheel rim assembly 1 can inflate the air bag 4, so that the air pressure of the air bag 4 reaches the maximum, i.e., can be equal to the air pressure of the tire 12, at this time, the right front wheel thrust F2 can reach the maximum, the direction of the right front wheel thrust F2 can be toward the right front, the length of the force arm of the center of gravity of the vehicle 10 in water to the right front wheel thrust F2 can be L2; similarly, the length of the force arm of the center of gravity of the vehicle 10 to the left front wheel thrust F1 can be L1, wherein the direction of the left front wheel thrust F1 can be toward the left rear; then the inflation amount of the left front wheel air bag 4, i.e., the air pressure value, can be controlled to adjust the left front wheel thrust F1, so that F1=F2×L2 / L1, so that the thrusts F1 and F2 generated by the left and right wheels can not make the vehicle 10 rotate in water, i.e., the torques of the left and right wheels can be in a balanced state. Since L2 is less than L1, F2 can be greater than F1, and finally the resultant force F of the vehicle 10 can be toward the vector sum of F1 and F2, i.e., the direction of the right front wheel thrust F2, and finally the vehicle 10 can drive to the right front. It should be pointed out that when the front axle wheel turns to the limit, the value of the resultant force F of the vehicle 10 is the maximum, and the speed of the vehicle 10 driving in water is the fastest.

[0113] In one possible implementation, the vehicle 10 can travel straight in water towards the left rear, at this time the front axle wheel rim assembly 1 can be offset to the left relative to the vehicle body 11 and rotate counterclockwise, the right front wheel rim assembly 1 can inflate the air bag 4, so that the air pressure of the air bag 4 reaches the maximum, that is, can be equal to the air pressure of the tire 12, at this time the right front wheel thrust F2 can reach the maximum, the direction of the right front wheel thrust F2 can be towards the left rear, the length of the force arm of the vehicle 10 center of gravity in water to the right front wheel thrust F2 can be L2; Similarly, the length of the force arm of the vehicle 10 center of gravity to the left front wheel thrust F1 can be L1, wherein the direction of the left front wheel thrust F1 can be towards the right front; Then the inflation amount of the left front wheel air bag 4, that is, the air pressure value can be controlled to adjust the left front wheel thrust F1, so that F1=F2xL2 / L1, so that the thrust F1 and F2 generated by the left and right wheels can not make the vehicle 10 rotate in water, that is, the torque of the left and right wheels can be in a balanced state. Since L2 is less than L1, F2 can be greater than F1, and finally the resultant force F of the vehicle 10 can be towards the vector sum of F1 and F2, that is, the resultant force F can be towards the direction of the right front wheel thrust F2, and finally the vehicle 10 can travel towards the left rear.

[0114] In one possible implementation, the vehicle 10 can travel straight in water towards the left rear, at this time the front axle wheel rim assembly 1 can be offset to the left relative to the vehicle body 11 and rotate counterclockwise, the right front wheel rim assembly 1 can inflate the air bag 4, so that the air pressure of the air bag 4 reaches the maximum, that is, can be equal to the air pressure of the tire 12, at this time the right front wheel thrust F2 can reach the maximum, the direction of the right front wheel thrust F2 can be towards the left rear, the length of the force arm of the vehicle 10 center of gravity in water to the right front wheel thrust F2 can be L2; Similarly, the length of the force arm of the vehicle 10 center of gravity to the left front wheel thrust F1 can be L1, wherein the direction of the left front wheel thrust F1 can be towards the right front; Then the inflation amount of the left front wheel air bag 4, that is, the air pressure value can be controlled to adjust the left front wheel thrust F1, so that F1=F2xL2 / L1, so that the thrust F1 and F2 generated by the left and right wheels can not make the vehicle 10 rotate in water, that is, the torque of the left and right wheels can be in a balanced state. Since L2 is less than L1, F2 can be greater than F1, and finally the resultant force F of the vehicle 10 can be towards the vector sum of F1 and F2, that is, the resultant force F can be towards the direction of the right front wheel thrust F2, and finally the vehicle 10 can travel towards the left rear.

[0115] In one possible embodiment, the vehicle 10 can travel straight toward the right rear in the water. At this time, the front axle rim assembly 1 can be offset to the right relative to the vehicle body 11 and rotate counterclockwise. The right front wheel rim assembly 1 can inflate the airbag 4 so that the air pressure of the airbag 4 reaches the maximum, that is, it can be equal to the air pressure of the tire 12. At this time, the right front wheel thrust F2 can reach the maximum, and the direction of the right front wheel thrust F2 can be toward the left front. The length of the lever arm from the force center of the vehicle 10 in the water to the right front wheel thrust F2 can be L2; similarly, the length of the lever arm from the force center of the vehicle 10 to the left front wheel thrust F1 can be L1, where the direction of the left front wheel thrust F1 can be toward the right rear; then the inflation amount of the left front wheel airbag 4, that is, the air pressure value, can be controlled to adjust the left front wheel thrust F1, so that F1=F2×L2 / L1, so that the thrusts F1 and F2 generated by the left and right wheels can not cause the vehicle 10 to rotate in the water, that is, the torque of the left and right wheels can be in a balanced state. Since L2 is greater than L1, F1 can be greater than F2, and finally the resultant force F of the vehicle 10 can be toward the vector sum of F1 and F2, that is, the resultant force F can be toward the direction of the left front wheel thrust F1, that is, the right rear, and finally the vehicle 10 can move toward the right rear.
