[0027] This application provides a vehicle submersion protection device and a vehicle. The vehicle submersion protection device and vehicle of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0028] Figure 1 The diagram shown is a structural schematic of a vehicle submersion protection device 1 according to an exemplary embodiment of this application. (Reference) Figure 1A vehicle submersion protection device 1 is installed on a vehicle 100. The vehicle submersion protection device 1 includes multiple buoyancy airbags 2, a sensor assembly 3, and a control assembly 4. The multiple buoyancy airbags 2 are located at the top and bottom of the vehicle 100. In this embodiment, the multiple buoyancy airbags 2 are located near the bottom edge of the vehicle 100 at the top and bottom. The sensor assembly 3 is installed on the vehicle 100. Specifically, the sensor assembly 3 can be located around the vehicle 100 to obtain the tilt angle of the vehicle 100. The sensor assembly 3 is used to detect the tilt angle of the vehicle 100 and output a corresponding detection signal. In some embodiments, the current angle value can be calculated using sensors such as gyroscopes and accelerometers to obtain the tilt angle of the vehicle 100. The control assembly 4 is installed on the vehicle 100. In this embodiment, the control assembly 4 can be located in the middle of the vehicle 100 to facilitate wiring harness arrangement; this application does not impose any limitations on this. The control assembly 4 is connected to the sensor assembly 3 and the multiple buoyancy airbags 2. Control component 4 receives detection signals and controls the inflation of some of the multiple buoyancy airbags 2 based on these signals. When the detection signal indicates that the tilt angle of vehicle 100 has exceeded a tilt angle threshold, some of the buoyancy airbags 2 at the top of vehicle 100 are opened to right the overturned vehicle 100. Simultaneously with righting the vehicle 100, all the buoyancy airbags 2 at the bottom of vehicle 100 are opened, allowing the vehicle 100 to float on the water surface. When the detection signal indicates that the tilt angle of vehicle 100 has not exceeded the tilt angle threshold, some of the buoyancy airbags 2 at the bottom of vehicle 100 are opened to right the overturned vehicle 100. Simultaneously with righting the vehicle 100, the remaining buoyancy airbags 2 at the bottom of vehicle 100 are opened, allowing the vehicle 100 to float on the water surface. This configuration solves the problem of vehicle overturning after entering water, resulting in higher safety.

[0029] The sensor assembly 3 receives the signal of the tilt angle of the vehicle 100 and outputs it to the control assembly 4. The control assembly 4 controls multiple buoyancy airbags located at the top and bottom of the vehicle 100 to inflate according to the received tilt angle signal of the vehicle 100 so that the tilted vehicle 100 can be righted and float on the water surface. This can solve the problem of the vehicle 100 flipping after entering the water and improve safety.

[0030] In some embodiments, the sensor assembly 3 includes a balance sensor 30 disposed on the vehicle 100, used to detect the tilt angle of the vehicle 100 and output a first detection signal. In embodiments of this application, the balance sensor 30 is disposed near the control assembly 4 to facilitate wiring harness arrangement. The control assembly 4 is used to receive the first detection signal and, when the first detection signal indicates that the tilt angle of the vehicle 100 has reached a tilt angle threshold, control the inflation of a portion of the multiple buoyancy airbags 2. The control assembly 4 may be disposed in the middle of the vehicle 100 to facilitate wiring harness arrangement; this application does not impose any limitation on this. The balance sensor 30 is used to detect the tilt angle of the vehicle 100. Specifically, when the balance sensor 30 detects that the tilt angle of the vehicle 100 is less than 90 degrees, it outputs a corresponding first detection signal to the control assembly 4. The control assembly 4 receives the first detection signal and controls the inflation of the buoyancy airbags 2 located at the bottom of the vehicle 100. When the balance sensor 30 detects that the tilt angle of the vehicle 100 is greater than 90 degrees, it outputs a corresponding first detection signal to the control component 4. The control component 4 receives the first detection signal and controls the buoyancy airbag 2 located on top of the vehicle 100 to inflate, so that the buoyancy airbag 2 returns to its upright position. This configuration can make the tilted vehicle upright and float on the water surface, solving the problem of the vehicle flipping over after entering the water, thus improving safety.

[0031] In some embodiments, the sensor assembly 3 includes a plurality of radar sensors 31 disposed on the vehicle 100; the vehicle submersion protection device 1 includes a power assembly 5 connected to a plurality of buoyancy airbags 2, the power assembly 5 being used to actuate the buoyancy airbags 2 and control the inflation or deflation of the buoyancy airbags 2. The radar sensors 31 are used to detect the submersion depth of the vehicle 100 and output a second detection signal. The control assembly 4 is also electrically connected to the power assembly 5 and the radar sensors 31, and is used to receive the second detection signal and control the power assembly 5 according to the second detection signal to control the inflation or deflation of the buoyancy airbags 2 according to the tilt angle of the vehicle 100. (Reference) Figure 1In this embodiment, radar sensors 31 are disposed around the vehicle 100 to detect whether the vehicle 100 has fallen into the water and the depth of the vehicle 100 in the water, and output a second detection signal. The control component 4, based on the detected water depth around the vehicle 100, controls the power component to inflate or deflate multiple buoyancy airbags 2 according to the second detection signal. Since the vehicle 100 enters the water at different angles and at different times, the control component 4 controls the buoyancy airbag 2 on the side that enters the water first to open first, followed by the other buoyancy airbags 2, to control the vehicle 100 to return to its upright position. Due to the imbalance of the vehicle 100's center of gravity, the power component 5 needs to inflate the buoyancy airbags 2 on the side with a deeper water depth or deflate the buoyancy airbags 2 on the side with a shallower water depth to maintain the balance of the vehicle 100. In other embodiments, the water surface in the area where the vehicle 100 enters the water is subject to wave changes. By detecting the water depth around the vehicle 100 using radar sensor 31, the changes in wind and waves can be known, allowing for dynamic adjustment of the size of the buoyancy airbags 2 to cope with the changes in wind and waves and prevent the vehicle 100 from being overturned by the waves. Specifically, the vehicle 100 is prevented from overturning by deflating the buoyancy airbags 2 on the windward side and inflating the buoyancy airbags 2 on the leeward side.

[0032] In some embodiments, the control component 4 includes a separately configured vehicle controller 40 and an airbag controller 41, both located in the vehicle 100. The vehicle controller 40 is electrically connected to the radar sensor 31, the balance sensor 30, and the airbag controller 41, respectively. The airbag controller 41 is connected to multiple buoyancy airbags 2 via a power component 5. The vehicle controller 40 receives a first detection signal output by the balance sensor 30 and a second detection signal output by the radar sensor 31, processes the first and second detection signals, and sends them to the airbag controller 41. The airbag controller 41 controls the corresponding power component 5 according to the control command processed by the vehicle controller 40. In the embodiments of this application, the airbag controller 41 is positioned between the vehicle controller 40 and the multiple buoyancy airbags 2. The airbag controller 41 receives the control command from the vehicle controller 40 and controls the corresponding power component 5 according to the control command, so that the vehicle controller 40 does not need to be directly connected to the multiple buoyancy airbags 2. This configuration reduces the number and complexity of the wiring harness between the control component 4 and the power component. Furthermore, the vehicle controller 40 and the airbag controller 41 are separately configured, with the vehicle controller 40 located at the front or rear of the vehicle 100 and the airbag controller 41 located in the middle of the vehicle 100. The airbag controller 41 can serve as a signal adapter board, simplifying the circuit boards of the vehicle controller 40 and the airbag controller 41.

[0033] In some embodiments, the vehicle submersion protection device 1 includes multiple power components 5, which are correspondingly arranged with multiple buoyancy airbags 2. Each power component 5 includes an air replenishment and pressurization pump 50 and an airbag control component 51 connected to the air replenishment and pressurization pump 50. The air replenishment and pressurization pump 50 is connected to the buoyancy airbag 2, and the airbag control component 51 is electrically connected to the airbag controller 41. The airbag control component 51 receives control commands from the vehicle controller 40 and controls the corresponding airbag control component 51 according to the control commands to control the inflation or deflation of the corresponding buoyancy airbag 2. The airbag control component 51 includes an airbag inflation unit (not shown) and an airbag replenishment unit (not shown), with the airbag inflation unit connected to the buoyancy airbag 2. In embodiments of this application, the airbag inflation unit controls the inflation of the buoyancy airbag 2 after receiving a control command. The airbag replenishment unit inflates or deflates the buoyancy airbag 2 connected to the airbag replenishment unit. When sensor assembly 3 detects that vehicle 100 has fallen into water, vehicle controller 40 sends a control command to airbag controller 41. Airbag controller 41 receives the control command and controls the corresponding airbag inflation unit. The airbag inflation unit controls the buoyancy airbag 2 on the side with deeper water depth to inflate first, followed by the other buoyancy airbags 2, so that vehicle 100 is righted and floats on the water surface. When sensor assembly 3 detects that vehicle 100 is tilted due to imbalance, vehicle controller 40 sends a control command to airbag controller 41. Airbag controller 41 receives the control command and controls the corresponding airbag inflation unit. The airbag inflation unit inflates the buoyancy airbag 2 on the side with deeper water depth or deflates the buoyancy airbag 2 on the side with shallower water depth according to the control command sent by vehicle controller 40. When sensor assembly 3 detects changes in the water surface in the area where vehicle 100 has fallen into the water, it dynamically adjusts the size of the buoyancy airbags 2 to cope with changes in wind and waves to prevent vehicle 100 from being capsized by waves. Specifically, the airbag inflation unit deflates the buoyancy airbag 2 on the windward side according to the control command sent by the vehicle controller 40, or inflates the buoyancy airbag 2 on the leeward side according to the control command sent by the vehicle controller 40 to prevent the vehicle 100 from overturning, or the airbag inflation unit simultaneously inflates the buoyancy airbag 2 on the leeward side and deflates the buoyancy airbag 2 on the windward side according to the control command sent by the vehicle controller 40.

[0034] In some embodiments, the vehicle 100 includes a vehicle bottom surface 101, which is located on the chassis of the vehicle 100. The vehicle bottom surface 101 includes a first bottom edge 102 and a second bottom edge 103 disposed opposite to each other, and a plurality of buoyancy airbags 2 are disposed near the first bottom edge 102 and the second bottom edge 103. The vehicle 100 also includes a vehicle top surface (not shown), which is located on the side of the vehicle 100 relatively away from the chassis. The vehicle top surface includes a third bottom edge and a fourth bottom edge disposed opposite to each other, and a plurality of buoyancy airbags 2 are disposed near the third bottom edge and the fourth bottom edge. The first bottom edge 102, the second bottom edge 103, the third bottom edge, and the fourth bottom edge are the bottom edges on both sides of the vehicle 100, extending along the length of the vehicle body. When the vehicle 100 overturns, the multiple buoyancy airbags 2 disposed on the third bottom edge or the fourth bottom edge of the vehicle top surface can restore the vehicle 100 to its upright position. In the embodiments of this application, five buoyancy airbags 2 are respectively arranged near the first bottom edge 102 and the second bottom edge 103. This arrangement allows for precise adjustment of the tilting angle of the vehicle 100, preventing the vehicle 100 from tilting or even overturning due to a shift in the center of gravity or water waves. (Reference) Figure 1 In the embodiments of this application, multiple buoyancy airbags 2 are arranged on the bottom edge along the width direction of the vehicle body, near the front and rear sides of the vehicle 100. The length of the buoyancy airbags 2 arranged along the sides of the vehicle 100 along the length direction of the vehicle body is greater than the length of the buoyancy airbags arranged along the front and rear sides of the vehicle 100 along the length direction of the vehicle body. This arrangement can prevent the vehicle 100 from overturning when the water surface is rough.

[0035] Figure 2 The diagram shown is a partial schematic block diagram of a vehicle submersion protection device according to an exemplary embodiment of this application. (Reference) Figure 2In some embodiments, the vehicle submersion device 1 further includes a distress signal device 6, which is located at the control component 4 and electrically connected to the control component 4. The control component 4 is used to control the distress signal device 6 to send a distress signal when it receives a detection signal indicating that the vehicle 100 has tipped over. Specifically, in one embodiment, the distress signal device 6 has a waterproof exterior and includes a controller 61, a communication module 62, and a GPS positioning module 63 internally. The controller 61 is electrically connected to the vehicle controller 40, the communication module 62, and the GPS positioning module 63. The GPS positioning module 63 sends the vehicle 100's location information to the controller 61. The vehicle controller 40 receives the first and second detection signals from the radar sensor 31 and the balance sensor 30 and sends control commands to the controller 61. After receiving the control commands, the controller 61 controls the communication module 62 to send a distress signal and the vehicle's location information to nearby rescue departments. This can speed up rescue efforts and reduce losses from accidents. In addition, the distress signal device 6 has an independent battery to prevent it from malfunctioning after the vehicle 100 falls into the water.

[0036] Figure 3 The diagram shown is a partial schematic block diagram of a vehicle submersion protection device 1 according to another exemplary embodiment of this application. (Reference) Figure 3 In some embodiments, the vehicle 100 includes a main power supply 7, typically located at the front, rear, or middle of the vehicle 100. The control component 4 is electrically connected to the main power supply 7. The vehicle submersion protection device 1 also includes a backup battery 70, which is positioned close to the main power supply 7. The backup battery 70 is connected to the main power supply 7 and is used to supply power to the vehicle's onboard devices when the main power supply 7 fails. The backup battery 70 is a storage battery; when the main power supply 7 is working normally, it charges the backup battery 70. When the vehicle is partially submerged in water, the main power supply 7 may malfunction and fail to supply power normally; the backup battery 70 can continue to supply power to the vehicle submersion protection device 1. This configuration ensures a power supply, allowing the buoyancy airbag 2 to deploy normally and the power component 5 to inflate the buoyancy airbag 2 to prevent leakage.

[0037] refer to Figure 3The vehicle submersion protection device 1 includes multiple power components 5, located near the first bottom edge 102, second bottom edge 103, third bottom edge, or fourth bottom edge of the vehicle 100. The multiple power components 5 are correspondingly connected to multiple buoyancy airbags 2. The vehicle submersion protection device 1 also includes multiple airbag batteries 71, located within the crossbeam cavity near the first bottom edge 102, second bottom edge 103, third bottom edge, or fourth bottom edge of the vehicle 100. The multiple airbag batteries 71 are respectively connected to the multiple power components 5, and are used to power the power components 5. Each buoyancy airbag 2 is provided with an individual airbag battery 71, thereby ensuring that when some buoyancy airbags 2 malfunction, the remaining buoyancy airbags 2 can still deploy normally when the vehicle 100 falls into the water, allowing the vehicle 100 to float on the surface.

[0038] This application also provides a vehicle including the above-described... Figures 1 to 3 The vehicle submersion protection device 1 shown in the embodiment can, after the vehicle 100 falls into the water, deploy the corresponding buoyancy airbags 2 to allow the vehicle 100 to quickly right itself and float on the water surface. Furthermore, it can dynamically adjust at least some of the buoyancy airbags 2 to prevent the vehicle 100 from overturning when the vehicle 100's center of gravity is unstable or when the waves are large. The distress signal device 6 can promptly signal for help from nearby rescue units after the vehicle 100 falls into the water, thereby accelerating rescue efforts and reducing losses from the accident.
