[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0028] According to a first aspect of the invention, such as Figure 1 As shown, a vehicle floating system that has fallen into water is provided, comprising: A buoyancy airbag 40 is adapted to deploy to make the vehicle float when it falls into water; The tire pressure regulation system 30 is used to inflate the water-floating airbag 40.

[0029] By inflating the water-floating airbag 40 through the tire pressure regulation system 30, the vehicle can float on the water, ensuring sufficient time for self-rescue or waiting for rescue after the vehicle falls into the water.

[0030] In some embodiments, a water-fall detection module 10 is further included for collecting water-falling information of the vehicle. The water-fall detection module 10 includes one or more of a wading sensor, a radar sensor, a vision sensor, a water pressure sensor, and a water level sensor. The radar sensor includes one or more of ultrasonic radar, millimeter-wave radar, and lidar. The wading sensor sends a signal to the control system 20 when the water level reaches the sensor's position, providing wading information to the control system 20. The radar sensor sends scanning information to the control system 20, providing wading information to the control system 20. The vision sensor identifies the vehicle's wading status using a visual method, providing wading information to the control system 20. The water pressure sensor collects water pressure data, providing wading information to the control system 20. The water level sensor collects water level data, providing wading information to the control system 20. The control system 20 determines whether the vehicle is wading normally or has fallen into water based on the wading information, which includes one or more of water depth, water level, and water pressure.

[0031] In some embodiments, a control system 20 is also included, which, after identifying that the vehicle has fallen into the water based on wading information, controls the tire pressure regulation system 30 to inflate the buoyancy airbag 40 to make the vehicle float. like Figure 2 As shown, in some embodiments, the tire pressure regulation system 30 includes an air source, a main air passage 380, and a tire 340. The air source and the tire 340 are connected to the main air passage 380, and the floating airbag 40 is connected to the main air passage 380.

[0032] In some embodiments, the tire pressure regulation system 30 inflates the float airbag 40 through a first inflation mode, wherein the first inflation mode is to inflate the float airbag 40 through an air source.

[0033] In some embodiments, the tire pressure regulation system 30 inflates the water-floating airbag 40 through a second inflation mode, wherein the second inflation mode is to inflate the water-floating airbag 40 through an air source and the tire 340.

[0034] In some embodiments, the tire pressure regulation system 30 inflates the water-floating airbag 40 via a third inflation mode, wherein the fourth inflation mode is to inflate the water-floating airbag 40 via the tire 340.

[0035] In some embodiments, the air source includes an air pump 320 and an air tank 330, the air pump 320 being adapted to supply air to the air tank 330, and / or the tire 340, and / or the floating airbag 40.

[0036] In some embodiments, the air outlet of the air pump 320 is connected to the main air circuit 380, the air tank 330 is connected to the main air circuit 380, the tire 340 is connected to the main air circuit 380, and the water-floating airbag 40 is connected to the main air circuit 380. The tire pressure regulation system is a system originally equipped in the vehicle, used to inflate and deflate the tire 40 during normal driving. Adding the water-floating airbag 40 to this system results in a relatively low additional cost.

[0037] In some embodiments, the tire pressure regulation system 30 further includes a control valve group, which controls the connection and disconnection between the air tank 330 and the main air passage 380, the connection and disconnection between the tire 340 and the main air passage 380, and the connection and disconnection between the floating airbag 40 and the main air passage 380.

[0038] In some embodiments, the control valve assembly includes a tire control valve 355, and the tire 340 is connected to the main air passage 380 through the tire control valve 355.

[0039] In some embodiments, the control valve assembly includes a wheel-side control valve 361, which is located at the air inlet of the tire 340. The wheel-side control valve 361 has a high accuracy in opening and closing, and controls the opening and closing of the air inlet by opening and closing, so as to inflate and deflate the tire to meet the different tire pressure requirements under different road conditions. In addition, when the vehicle falls into water, the air passage is opened to inflate the floatation airbag 40 with the tire 340, and the high-pressure gas of the tire 340 can be accurately controlled to be injected into the floatation airbag 40, so that the vehicle floats on the water surface.

[0040] In some embodiments, the control valve assembly includes an airbag control valve 356, and the floating airbag 40 is connected to the main air passage 380 through the airbag control valve 356. The airbag control valve 356 is adapted to control the on / off connection between the airbag and the main air passage 380.

[0041] In some embodiments, a gas pressure sensor 393 is provided inside the gas storage tank 330 to detect the gas pressure inside the gas storage tank 330.

[0042] The first inflation mode inflates the floating airbag 40 through an air source. The air source can output high-pressure gas, resulting in high inflation efficiency.

[0043] The second inflation mode inflates the floating airbag 40 simultaneously through the air source and the tire 340. It has the highest inflation efficiency, but it consumes the gas stored in the air tank 330 and the tire 340, and needs to be re-inflated later.

[0044] The third inflation mode inflates the floating airbag 40 through the tire 340. The air tank 330 may not always contain enough gas. When the gas in the air tank 330 is insufficient, the floating airbag 40 is inflated only through the tire 340.

[0045] In some embodiments, the tire pressure regulation system 30 further includes a controller 310 for controlling the opening and closing of each valve in the control valve group and the operation of the air pump 320.

[0046] In some embodiments, the gas storage tank 330 is connected to the main gas line 380 via a first control valve 351.

[0047] In some embodiments, when the first inflation mode is running, if the power supply to the air pump 320 is normal and the air inlet of the air pump 320 is higher than the water surface, the air pump 320 can work normally. The controller 310 controls the air pump 320 to start, the first control valve 351 opens, the tire control valve 355 and the wheel-side control valve 360 ​​close, the airbag control valve 356 opens, and gas is filled into the floating airbag 40 from the air pump 320 and the air tank 330.

[0048] In some embodiments, when the first inflation mode is running, if the air pump 320 loses power and / or water enters the air inlet of the air pump 320, the air pump 320 cannot work normally. The controller 310 controls the first control valve 351 to open, the tire control valve 355 and the wheel-side control valve 360 ​​to close, and the airbag control valve 356 to open, so that gas is filled from the air tank 330 into the floating airbag 40.

[0049] In some embodiments, when the second inflation mode is running, if the power supply to the air pump 320 is normal and the air inlet of the air pump 320 is higher than the water surface, the air pump 320 can work normally. The controller 310 controls the air pump 320 to start, and the first control valve 351, the tire control valve 355, the wheel side control valve 360 ​​and the airbag control valve 356 are all opened, and gas is inflated from the air pump 320, the air tank 330 and the tire 340 into the floating airbag 40.

[0050] In some embodiments, when the second inflation mode is running, if the air pump 320 loses power and / or water enters the air inlet of the air pump 320, the air pump 320 cannot work normally. The controller 310 controls the first control valve 351, the tire control valve 355, the wheel-side control valve 360 ​​and the airbag control valve 356 to open, and gas is inflated from the air tank 330 and the tire 340 into the floating airbag 40.

[0051] In some embodiments, when the third inflation mode is running, the air pump 320 is not started, the controller 310 controls the first control valve 351 to close, the tire control valve 355 and the wheel-side control valve 360 ​​to open, the airbag control valve 356 to open, and gas is inflated from the tire 340 into the floating airbag 40.

[0052] The air pump 320 is powered by the vehicle's high-voltage power supply system. In the event of a vehicle falling into water, the vehicle may shut down the high-voltage power supply system to ensure safety. However, the controller 310, first control valve 351, tire control valve 355, wheel-side control valve 360, and airbag control valve 356 are all powered by a low-voltage system. In the event of a vehicle falling into water, the vehicle will not shut down the low-voltage system. Therefore, when the air pump 320 loses power, the controller 310, first control valve 351, tire control valve 355, wheel-side control valve 360, and airbag control valve 356 can still operate normally.

[0053] In some embodiments, the vehicle has four tires 340, including a first tire 341, a second tire 342, a third tire 343, and a fourth tire 344. A first wheel-side control valve 361 is provided at the air passage interface of the first tire 341, a second wheel-side control valve 362 is provided at the air passage interface of the second tire 342, a third wheel-side control valve 363 is provided at the air passage interface of the third tire 343, and a fourth wheel-side control valve 364 is provided at the air passage interface of the fourth tire 344. The first tire 341 is connected to the main air passage 380 via the first tire control valve 3551, the second tire 342 is connected to the main air passage 380 via the second tire control valve 3552, the third tire 343 is connected to the main air passage 380 via the third tire control valve 3553, and the fourth tire 344 is connected to the main air passage 380 via the fourth tire control valve 3554.

[0054] In some embodiments, a drying tank 370 is provided between the outlet of the air pump 310 and the main air passage 380. After the gas is pumped out from the outlet of the air pump 310, it passes through the drying tank 370 and enters the main air passage 380. Water is produced when air is compressed under high pressure by the air pump 20. This water can affect the operation of the control valve and corrode metal components. The drying tank 370 absorbs the water produced after the air pump 20 compresses under high pressure, thus protecting the control valve and its components.

[0055] In some embodiments, the main gas path 380 is also connected to the exhaust port 353 via a second control valve 352, and the exhaust port 353 is used to discharge excess gas in the main gas path 380 to the outside.

[0056] In some embodiments, the air inlet of the air pump 320 is provided with a water immersion sensor to detect the water immersion status of the air inlet of the air pump 320.

[0057] In some embodiments, a main air pressure sensor 392 is provided in the main air passage 380 to detect the air pressure in the main air passage 380. When the tire pressure regulation system 30 inflates the floating airbag 40 until the air pressure in the main air passage 380 reaches a preset value or no longer changes, the controller 310 closes the airbag control valve 356.

[0058] In some embodiments, the central charging and discharging system 30 further includes a third control valve 354, which serves as an expansion interface for supplying gas to other gas-using devices.

[0059] In some embodiments, the buoyancy airbag 40 includes a first buoyancy airbag 41 and a second buoyancy airbag 42. The first buoyancy airbag 41 is connected to the main air passage 380 through a first airbag control valve 3561, and the second buoyancy airbag 42 is connected to the main air passage 380 through a second airbag control valve 3562.

[0060] In some embodiments, such as Figure 3 As shown, the first control valve 351, the second control valve 352, the third control valve 354, the main air circuit pressure sensor 392, the first tire control valve 3551, the second tire control valve 3552, the third tire control valve 3553, the fourth tire control valve 3554, the first airbag control valve 3561 and the second airbag control valve 3562 are integrated into the control valve integration module 350.

[0061] In some embodiments, such as Figure 4 As shown, the wheel-side control valve 360 ​​includes a valve core 3601 and a control module 3602. The valve core 3601 controls the opening and closing of the air passage by opening and closing, allowing the tires to inflate and deflate, meeting the different tire pressure requirements under different road conditions. Furthermore, when the vehicle falls into water, the air passage is opened to inflate the floating airbag 40 using the tires 340. The control module 3602 includes a wireless transceiver module, a power supply module, and a tire pressure detection module. The wireless transceiver module is used to communicate with the controller 310, the power supply module provides power to the wheel-side control valve 360, and the tire pressure detection module is used to detect the tire pressure of the tires 340.

[0062] In some embodiments, the maximum displacement of the inflatable airbag 40 after inflation is not less than the weight of the vehicle, thereby enabling the vehicle to achieve a good buoyancy.

[0063] In some embodiments, the vehicle is provided with a plurality of buoyancy airbags 40, which, when inflated, are adapted to make the vehicle float stably on the water surface, and the sum of the maximum displacement of the plurality of buoyancy airbags 40 is not less than the weight of the vehicle.

[0064] In some embodiments, such as Figures 5-6 As shown, multiple water-floating airbags are respectively installed in the front and rear compartments of the vehicle chassis.
