Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0024] Firstly, the application scenarios applicable to the present application are introduced. The present application can be applied to the field of vehicle technology. It is found through research that, with the continuous growth of the number of cars and the increasing complexity of road transportation scenarios, the probability of vehicle falling into water accidents is on the rise. Such accidents are often accompanied by emergency situations such as difficulty in opening the doors and windows due to water pressure, and the escape time of the driver and passengers is greatly compressed, and their life safety is seriously threatened. At present, the solution to the vehicle falling into water is to equip the vehicle with a manual window breaker. The manual window breaker is stored in the storage compartment, glove box, etc. of the vehicle, and needs to be manually operated by the driver and passengers to break the window after the accident occurs, so as to open an escape channel.

[0025] However, the driver and passengers are easy to panic after the vehicle falls into water, especially in chaotic environments such as darkness and water flowing in, it is difficult to quickly locate and use the window breaker, and manual window breaking needs to consume a lot of physical strength under the condition of water pressure locking the doors and windows, further prolonging the escape time. In addition, for the weak groups such as the elderly, children, and the disabled, their physiological functions and emergency response abilities are weak, and they may not be able to escape independently due to their inability to operate the window breaker. And the existing technology only relies on a single window breaking escape path, once the main escape path fails, the driver and passengers will have no escape channel available, resulting in insufficient reliability and safety of the overall escape.

[0026] Based on this, the embodiments of the present application provide a vehicle falling into water intelligent escape system, which helps to improve the efficiency and safety of personnel escape after falling into water. Please refer to Figure 1 , Figure 1 is a structural schematic diagram of a vehicle falling into water intelligent escape system provided by an embodiment of the present application. As shown in Figure 1 and Figure 2As shown in the above embodiments, the vehicle falling into water intelligent escape system provided by the embodiments of the present application comprises an automatic window breaking module, a buoyancy assisting module and a control module, the automatic window breaking module and the buoyancy assisting module are connected with the control module respectively, the automatic window breaking module is installed at the corner positions of the front and rear windshields and the four side windows of the vehicle; the automatic window breaking module comprises a water pressure sensor and a miniature window breaking driving assembly 20, and the water pressure sensor and the miniature window breaking driving assembly 20 are connected with the control module respectively; the buoyancy assisting module comprises a gas generating device, an inflatable buoyancy guiding bag 10 and a buoyancy guiding carpet 60, the gas generating device is built-in the inflatable buoyancy guiding bag 10, the gas generating device is connected with the control module, the inflatable buoyancy guiding bag 10 is pre-installed inside the window frame of the four side windows, and the buoyancy guiding carpet 60 is laid on the vehicle compartment floor near the vehicle door; wherein, when the water pressure sensor detects that the water pressure reaches a preset threshold, the control module controls the miniature window breaking driving assembly 20 to trigger window breaking, and after the window breaking, the control module controls the gas generating device to inflate the inflatable buoyancy guiding bag 10 to provide buoyancy guidance.

[0027] The automatic window breaking module is an integrated assembly with water pressure sensing triggering function and can automatically break the window, which can respond to the water pressure signal in real time and perform the window breaking action without manual intervention. After the vehicle falls into water, the window breaking can be triggered without manual operation, thereby providing an escape channel for the passengers. In an optional embodiment, the automatic window breaking module can be designed in a modular manner and can be adapted to the window size of different vehicle models. The installation position of the automatic window breaking module avoids the field of view of the window, thereby ensuring that the normal driving field of view of the driver is not affected. For example, one automatic window breaking module is embedded at the corner of the front windshield and the upper and lower corners of the four side windows of a sedan, respectively. The outer dimension of each module can match the corner radius of the window, and after installation, the module is flush with the surface of the window, so as not to affect the normal appearance and use of the window. The buoyancy assisting module is a combined assembly with inflatable buoyancy function and escape guiding function, which forms buoyancy support and visual guidance at the same time of window breaking, thereby slowing down the water inflow speed and helping the passengers to quickly locate the escape exit. In an optional embodiment, the buoyancy assisting module can be composed of the inflatable buoyancy guiding bag 10, the buoyancy guiding carpet 60 and the matched gas generating device, and the overall design takes into account the practicability and concealment, thereby not affecting the normal use of the vehicle. For example, the inflatable buoyancy guiding bag 10 is hidden inside the window frame after being folded, and the buoyancy guiding carpet 60 is laid on the vehicle compartment floor near the vehicle door. Both of them do not occupy extra space and do not affect the passengers to get on and off the vehicle and the window lifting in the non-working state. The control module is a core control unit of the vehicle falling into water intelligent escape system, has signal receiving, logic judging and instruction sending functions, is used for receiving detection signals of each module and controlling each execution component to work cooperatively according to a preset logic, and a core role thereof is to coordinate working time sequences of the automatic window breaking module and the buoyancy auxiliary module, and to ensure that each module is triggered in order according to the preset logic. Exemplarily, the control module can adopt a vehicle-mounted MCU chip, has a waterproof and dustproof design, is installed in a waterproof box in the vehicle center console, and is in communication connection with the automatic window breaking module and the buoyancy auxiliary module through a CAN bus. For example, the control module can receive a water pressure sensor signal of the automatic window breaking module, judge whether a window breaking triggering condition is reached, and send an inflation instruction to the buoyancy auxiliary module, so as to realize synchronous starting of window breaking and inflation. Here, the installation position of the automatic window breaking module is a corner position of front and rear windshields and four side windows of the vehicle. The position can avoid a visual field area and a stress core area of the vehicle window, ensures normal driving, and guarantees the window breaking effect. Specifically, the corner position refers to a region 5-10 cm away from an edge of the vehicle window. The region neither blocks the front and side views of the driver, nor makes the glass fragments more likely to fall off after window breaking, so that an overall blockage is avoided. For example, on the four side windows of an SUV, the automatic window breaking module is installed at a lower corner position of the vehicle window. The position is close to the door, and an escape channel close to the door is formed after window breaking, so that passengers can quickly evacuate. Optionally, the water pressure sensor is a high-precision sensing element with a water pressure detection function, is used for monitoring water pressure changes around the vehicle in real time, sends a triggering signal to the control module when the water pressure reaches a preset threshold, and serves as a judgment basis for a window breaking instruction. Exemplarily, the water pressure sensor can adopt a waterproof level IP68 piezoresistive sensor, the measurement range is 0-0.1 MPa, the accuracy can reach ±0.001 MPa, the water level change after the vehicle falls into water can be accurately identified, and the best window breaking opportunity is avoided due to detection delay. For example, the water pressure sensor is integrated at a front end of the automatic window breaking module, and an inductive surface thereof faces outward. When the vehicle falls into water, the water level rises, the water pressure gradually increases, the sensor converts the water pressure signal into an electric signal and transmits the electric signal to the control module, and whether the window breaking triggering condition is reached is judged by the control module. Optionally, the miniature window breaking driving assembly 20 refers to a driving unit with energy release function and capable of breaking the vehicle window glass. Its core function is to receive the window breaking instruction from the control module and quickly release energy to break the glass, ensuring no risk of flying debris. For example, the miniature window breaking driving assembly 20 can adopt a miniature explosive driving mode. The explosive charge is precisely calculated to generate only the impact force to break the glass. At the same time, the buffer structure absorbs the explosion impact force to avoid glass fragments flying and injuring people. For example, the explosive charge in the miniature window breaking driving assembly 20 is 0.5g, and the special explosive is treated by passivation. When the explosive is detonated, the impact force is concentrated on the local glass, causing the glass to form a network of cracks and then fall off. The edges of the fragments are passivated and will not cause scratches to the human body. Further, the buoyancy auxiliary module includes a gas generating device, an inflatable buoyancy guide bag 10, and a buoyancy guide carpet 60. The gas generating device is built into the inflatable buoyancy guide bag 10, and the gas generating device is connected to the control module. The inflatable buoyancy guide bag 10 is pre-installed on the inner side of the window frame of the four side windows. The buoyancy guide carpet 60 is laid on the vehicle compartment floor near the vehicle door. Here, the buoyancy auxiliary module is linked with the automatic window breaking module. The inflation and guide functions are triggered at the same time as the window breaking action is started, ensuring the timeliness of the escape guidance.

[0028] The gas generating device is a component with gas storage and release control function. Its core function is to provide the inflatable buoyancy guide bag 10 with a source of inflation gas and quickly release the gas to achieve instant inflation of the guide bag after receiving the instruction from the control module. Specifically, the gas generating device adopts a high-pressure sealed design and has the ability to quickly deflate and inflate. It can make the guide bag expand and form in a short time. For example, the gas generating device includes a miniature CO2 cylinder, an electromagnetic valve, and a pressure release channel. The cylinder capacity can be 500ml, and the working pressure is 10MPa. The inflation of the guide bag can be completed in 0.5 seconds, and the response time of the electromagnetic valve is not more than 10ms. For example, the CO2 cylinder is made of seamless stainless steel and contains liquid CO2. When the control module sends an inflation instruction, the electromagnetic valve opens, and the CO2 gas is quickly injected into the inflatable buoyancy guide bag 10 through the pressure release channel, causing it to quickly expand and form. Here, the inflatable buoyancy guide bag 10 is a flexible buoyancy component with folding storage and automatic inflation function, such as Figure 2As shown, after inflation, the annular buoyancy ring is formed, which can not only block the rapid influx of water flow, but also provide passengers with escape guidance through fluorescent identification. In an optional embodiment, the thickness of the inflatable buoyancy guide bag 10 in the folded state is between 4 mm and 6 mm. Preferably, the folded thickness of the inflatable buoyancy guide bag 10 can be selected as 4 mm, 5 mm or 6 mm, which can be flexibly adjusted according to the installation space of the vehicle window. For example, for compact cars with small window lifting track gap, a 4 mm thick guide bag is selected to ensure that the window does not jam during lifting; for SUVs and other vehicles with ample space, a 6 mm thick guide bag can be selected to improve the structural stability after inflation. The thickness range design not only ensures the concealment of the guide bag, but also ensures the buoyancy effect and structural strength after inflation, avoiding breakage due to too thin thickness or affecting the normal use of the window due to too thick thickness. For example, the inflatable buoyancy guide bag 10 is pre-installed on the inner side of the window frame of the four side windows, and is fixed by magic tape in the folded state without affecting the normal lifting of the window. When receiving the inflation instruction, it is quickly unfolded and inflated to surround the edge of the broken window to form a buffer barrier to block the water flow. For example, three fluorescent strips with a width of 2 cm are evenly sewn on the outer surface of the inflatable buoyancy guide bag 10, and the fluorescent strips are made of light-storing fluorescent materials that can emit light in the dark environment without power supply, with a light-emitting duration of not less than 30 minutes. For example, the fluorescent strips are distributed along the circumference of the annular guide bag, and the included angle between adjacent fluorescent strips is 120°, ensuring that the light-emitting identification can be observed from various angles in the vehicle cabin. Even under water or in a dark environment, passengers can quickly find the escape exit through the fluorescent guide. Optionally, the buoyancy guide carpet 60 refers to a ground laying component with floating function and guide identification, such as Figure 2 As shown, it can automatically float after the vehicle sinks, and can guide passengers to find the escape exit in the correct direction through the surface identification, especially suitable for chaotic or dark environments. In an optional embodiment, the material of the buoyancy guide carpet 60 is a lightweight sealing material, specifically a closed-cell foam material with a density less than water, which can automatically float after sinking, and the surface is printed with guide identification and the edge is treated with anti-slip. For example, the size of the buoyancy guide carpet 60 is 100 cm x 50 cm, which is laid in the area near the door of the vehicle floor, covering the path from under the seat to the door, ensuring that passengers can step on the carpet when getting up. The surface of the buoyancy guide carpet 60 is printed with fluorescent arrows. Here, the surface of the buoyancy guide carpet 60 is printed with fluorescent arrows by a silk screen printing process, the arrow direction points to the nearest window escape exit, and the fluorescent arrows use the same light-storing fluorescent material as the guide bag to ensure underwater visibility; at the same time, the buoyancy guide carpet 60 is made of light-weight closed-cell EVA material, which is a light-weight sealing material, does not absorb water, has strong buoyancy, and has certain elasticity and slip resistance. For example, the length of the fluorescent arrow is 15 cm, the width is 5 cm, the arrow spacing is 20 cm, and the arrows are continuously distributed along the length direction of the carpet. When the vehicle cabin is flooded, the carpet floats on the water surface, and passengers can move to the broken window position in the correct direction guided by the fluorescent arrows without visual observation, which is especially suitable for the escape guidance of the elderly, children and others in a panic state.

[0029] Further, the buoyancy guide is realized by the fluorescent identification of the annular buoyancy ring and the arrow guidance of the buoyancy guide carpet 60, which is suitable for complex environments such as darkness and underwater, and can guide passengers to move to the broken window position in the correct direction.

[0030] In actual application, when the water pressure sensor detects that the water pressure reaches the preset threshold value, the control module controls the miniature broken window driving assembly 20 to trigger the broken window, and after the broken window, the control module controls the gas generating device to inflate the inflatable buoyancy guide bag 10 to provide buoyancy guidance.

[0031] The preset threshold value is a water pressure critical value preset by the control module to trigger the broken window action, and the setting needs to consider the timeliness of triggering and false triggering protection. For example, the preset threshold value can be determined according to the water pressure value corresponding to the height of the vehicle door lower edge to ensure that the broken window is triggered before the water level rises to lock the vehicle door, while avoiding false triggering caused by a small amount of water or splashing. For example, the preset threshold value is set to 0.03 MPa, which corresponds to a water depth of about 30 cm. At this time, the water level is close to the lower edge of the vehicle door, and the vehicle door will be locked by water pressure. It is the best time to start the broken window.

[0032] Here, when triggering the broken window, the area farthest from the driver's operation area is preferred, which avoids false triggering and interference with driving operation. For example, after the control module issues a broken window instruction, the automatic broken window module of the rear two side windows is preferentially triggered, and if no complete broken window is detected within 3 seconds, the broken window of other windows is continuously triggered to ensure that at least two or more escape exits are formed.

[0033] For example, when the vehicle accidentally falls into the water, the automatic breaking window module installed on the corner of the vehicle window starts to work, and the built-in water pressure sensor monitors the water pressure in real time. When the water level rises to about 30 cm, the water pressure reaches the preset threshold of 0.03 MPa, the water pressure sensor transmits the signal to the control module, and the control module immediately issues an instruction to the miniature breaking window driving assembly 20, and preferentially triggers the breaking window action of the rear two sides of the vehicle window. The impact force of the miniature explosive releases to break the vehicle window to form an escape exit. If the vehicle window is not completely broken within 3 seconds, the control module continues to trigger the breaking window of other vehicle windows to ensure the number of escape exits. At the same time of breaking the window, the control module sends an inflation instruction to the gas generating device, and the built-in gas generating device (CO2 gas cylinder) quickly releases gas to make the inflatable buoyancy guiding bag 10 inflate to form a ring-shaped buoyancy ring within 1 second. The fluorescent strip on the surface emits light underwater, clearly marking the escape exit, while blocking the rapid inflow of external water flow and slowing down the rise of water level in the vehicle. At the same time, the closed-cell foam buoyancy guiding carpet 60 on the floor of the vehicle cabin automatically floats to the water surface, and the fluorescent arrow on the surface clearly points to the broken vehicle window position. Even in a dark, chaotic or underwater environment, passengers can quickly find the escape exit along the arrow direction, effectively solving the problem that passengers cannot quickly locate the exit in the traditional manual breaking window mode, and significantly improving the escape efficiency and safety.

[0034] In this way, the automatic breaking window module realizes intelligent triggering of breaking window after falling into the water, without the need for the driver and passenger to manually find the breaking window tool, effectively solving the problem of water pressure locking the doors and windows, preventing the breaking window. At the same time, the buoyancy auxiliary module blocks the inflow of water flow through the ring-shaped buoyancy ring and provides fluorescent identification, and cooperates with the arrow direction of the buoyancy guiding carpet 60 to help passengers quickly locate the escape exit in a dark, chaotic environment, significantly improving the safety and reliability of escape, giving the driver and passenger more escape time, and greatly improving the success rate of escape after falling into the water.

[0035] In an alternative embodiment, the application also includes an emergency breaking window module, which includes a manual breaking window assembly and an audible and visual reminder unit, and the audible and visual reminder unit is connected with the control module. When the automatic breaking window module fails, the control module controls the audible and visual reminder unit to issue a prompt to guide the user to trigger the breaking window of all vehicle windows through the manual breaking window assembly.

[0036] Here, the emergency window breaking module has a manual window breaking function and a failure prompting function. When the automatic window breaking module fails or does not completely break the vehicle window, a manual triggering mode and an audible and visual prompt are provided to ensure that an escape exit is still formed in an extreme situation, thereby ensuring the reliability of the escape channel. Optionally, the emergency window breaking module is integrated in the cockpit. The manual window breaking assembly can adopt a button type design, and the audible and visual prompting unit can adopt a combination of a buzzer and an LED indicator light, and communicates with the control module in real time. For example, the manual window breaking assembly of the emergency window breaking module is installed at the door armrest position on the left side of the driver's seat, and the audible and visual prompting unit is integrated above the button. When the control module detects that the automatic window breaking is not successful, the audible and visual prompting unit is immediately triggered to work. The manual window breaking assembly is an operating part that has a manual triggering function and can start the window breaking of the entire vehicle. When the automatic window breaking fails, the driver manually triggers it to ensure at least two or more escape exits. Here, the manual window breaking assembly can adopt a false touch prevention design and can be triggered only after being pressed for more than 3 seconds to avoid false operation in an emergency. For example, the manual window breaking assembly is a red protruding button with anti-slip lines on the surface. After being pressed, the internal contact is closed, a full-vehicle window breaking instruction is sent to the control module, the control module starts all the miniature window breaking drive assemblies 20 of the vehicle windows after receiving the instruction, and at least one of the front and rear rows of vehicle windows is broken to form multiple escape channels. The audible and visual prompting unit is a warning part that has a sound prompt and a light prompt function. When the automatic window breaking fails, it can quickly remind the driver to start the manual window breaking to avoid delaying the escape opportunity. For example, the buzzer of the audible and visual prompting unit emits a continuous buzzer sound with a frequency of 1 kHz, and the LED indicator light is in a red flashing state with a flashing frequency of 2 times per second to ensure that the driver can quickly perceive in a noisy or chaotic environment. For example, when the automatic window breaking module is started, if the control module does not detect a feedback signal of the vehicle window breaking (judged by the pressure feedback sensor built in the window breaker) within 3 seconds, the audible and visual prompting unit is immediately controlled to start and work continuously until the driver triggers the manual window breaking or the system is reset. In actual application, if the vehicle falls into water and the automatic window breaking module fails to break the vehicle window due to a fault, the control module detects that the window breaking action is not completed after 3 seconds, immediately determines that the automatic window breaking module is faulty, and starts the audible and visual prompting unit. After the driver sees the high-frequency flashing red light and hears the buzzer alarm, the protective cover of the manual window breaking button on the left side of the driver's seat is quickly opened, the button is pressed to trigger the window breaking of the entire vehicle, at least two escape exits are ensured, the escape dilemma caused by the failure of the automatic window breaking is avoided, and the reliability of the system is further improved.

[0037] The setting of the emergency window breaking module enables the system to have double window breaking guarantee of automatic and manual, when the automatic window breaking mechanism fails due to failure, the driver can be quickly guided to start the manual window breaking through the sound and light prompt, so as to avoid the escape channel being blocked due to single mechanism failure, further improve the reliability and safety of the system, and ensure that the passengers can still have an effective escape way under complex emergency conditions.

[0038] In an optional embodiment, the system provided by the embodiment of the application further includes a posture monitoring module connected with the control module; the posture monitoring module includes a pressure sensor, a posture sensor and a seat belt unlocking unit, the pressure sensor, the posture sensor and the seat belt unlocking unit are respectively connected with the control module, and the pressure sensor and the posture sensor are installed on the rear seats of the vehicle; wherein the pressure sensor is used to detect whether there is a passenger on the rear seats, the posture sensor is used to detect the body posture change condition of the passenger on the rear seats, and when it is detected that the body posture change condition of the passenger is abnormal, the control module controls the seat belt unlocking unit to unlock the rear seat belt.

[0039] The posture monitoring module is a protection module with passenger posture detection and emergency linkage functions, and is used for real-time monitoring of the posture state of the weak people in the rear row after falling into water, triggering linkage protection measures when an abnormality occurs, and reducing the difficulty of escape. Optionally, the posture monitoring module can be integrated in the rear seats, the sensors are installed in the seat sponge, the seat belt unlocking unit is connected with the lock buckle mechanism of the seat belt, and the control module works cooperatively with other systems. Specifically, the pressure sensor and the posture sensor of the posture monitoring module are installed in the seat cushion and the backrest of the seats on both sides of the rear row, and the seat belt unlocking unit is integrated in the seat belt lock buckle on the side of the seat. Specifically, the pressure sensor is a sensing component with pressure detection function and capable of judging whether there is a passenger on the seat, and its core role is to identify the seating state of the rear seat and provide a basis for judging the posture monitoring. For example, the pressure sensor can be a thin film pressure sensor, which is laid on the stress area of the seat cushion, the detection range is 0-100 kg, the accuracy can reach ±0.5 kg, and different weights of passengers such as adults and children can be accurately identified. For example, when the pressure sensor detects that the pressure value on the seat is greater than 5 kg, it is determined that there is a passenger on the seat, and the control module starts real-time monitoring of the posture sensor; if the pressure value is less than 5 kg, it is determined that there is no passenger, and the posture sensor is in a dormant state to reduce energy consumption. Specifically, the posture sensor is a sensing component with posture detection function and passenger abnormal posture recognition function. Its core function is to monitor the body posture of passengers after falling into water and determine whether there is a difficult escape situation. For example, the posture sensor can be a combination of a six-axis gyroscope and an acceleration sensor, installed at the connection between the backrest and the cushion of the rear seat, with a sampling frequency of 10 Hz, which can identify abnormal postures such as tilting, curling, and long-term stillness. For example, after the vehicle falls into water, the posture sensor collects the body angle and motion state of the passenger in real time. If the passenger's body tilt angle exceeds 45°, or there is no significant motion change within 10 seconds, or the posture data shows a curled posture, an abnormal signal is immediately sent to the control module. Among them, the body posture change situation is the posture state of the passenger detected by the posture sensor that cannot escape independently, including tilting, curling, and long-term immobility. Here, the determination standard of the body posture abnormality is based on the normal escape posture of the human body. When the detection parameter exceeds the preset normal range, it is determined to be abnormal. For example, the passenger's body tilt angle exceeds 45 degrees (may be due to nervousness and slipping), the curling degree reaches the preset threshold (may be unable to act due to panic), or there is no movement for 10 seconds (may be entangled by the safety belt), which are all determined to be posture abnormalities.

[0040] Here, the safety belt unlocking unit refers to an execution component with automatic unlocking function and can release the safety belt. When the passenger has an abnormal posture, the safety belt can be automatically unlocked to avoid being unable to manually unlock due to panic or limited limbs. Optionally, the safety belt unlocking unit can adopt an electromagnetic drive mode, with a response time of not more than 0.5 seconds. After unlocking, it can be re-locked manually without affecting normal use. For example, when the control module receives the abnormal signal of the posture sensor, it immediately sends an unlocking instruction to the safety belt unlocking unit, and the electromagnetic mechanism drives the safety belt lock to release. The action is smooth and has no impact. The passenger can directly escape from the safety belt restraint without the need to manually press the unlock button, which is especially suitable for the elderly and children who cannot accurately operate in panic. In practical application, after the vehicle falls into water, the pressure sensor in the cushion of the rear seat first detects a continuous pressure of more than 20 kg, and determines that there is a passenger in the rear seat. Then the posture sensor monitors in real time. If it is detected that the passenger's body tilt angle reaches 50 degrees (exceeding the normal range of 45 degrees) due to nervousness and slipping, it is immediately determined to be a posture abnormality and the signal is transmitted to the control module. The control module quickly issues an instruction to the safety belt unlocking unit, and the electromagnetic drive device instantly opens the safety belt lock to release the restraint, avoiding the passenger's inability to manually unlock due to panic and missing the escape opportunity, providing key protection for vulnerable groups.

[0041] In view of the characteristics of weak self-rescue ability and easy panic of the vulnerable groups such as the elderly, children and the disabled, the posture monitoring module is set up, the posture state is monitored in real time and the safety belt is automatically unlocked, so as to reduce the escape operation threshold of the vulnerable groups, avoid the situation that the safety belt binds the vulnerable groups and they cannot evacuate in time, provide exclusive evacuation guarantee for the vulnerable groups, further expand the scope of the applicable groups of the system, and improve the overall evacuation success rate.

[0042] Further, as shown in Figure 1 and Figure 2 , the system can also include an in-vehicle camera 50 for monitoring the state of the people in the vehicle to assist in the posture monitoring of the vulnerable groups. In this way, the in-vehicle camera 50 cooperates with the pressure sensor and the posture sensor of the rear seat to further accurately determine the state of the passengers, such as whether a child is wrapped in a safety belt or whether an old person cannot get up due to panic and falling down, so as to make up for the blind area of the pure physical sensor and ensure the accuracy of the determination of the evacuation difficulty.

[0043] In addition, in an environment such as darkness or underwater where the physical sensor is easily disturbed, the image acquisition of the in-vehicle camera 50 assists in confirming the position and state of the passengers, provides supplementary basis for the control module to trigger the safety belt unlocking, seat lifting and other linkage measures, and avoids false triggering or missed triggering.

[0044] The in-vehicle camera 50 and the posture sensor form a dual monitoring mechanism of physical sensing and image recognition, which not only ensures the accuracy of the posture determination of the vulnerable groups, but also further enhances the adaptability of the evacuation system to complex scenes and helps to improve the overall evacuation success rate.

[0045] In an optional embodiment, the posture monitoring module further includes a seat lifting device 30, the seat lifting device 30 is connected with the control module, and the seat lifting device 30 is installed between the bottom support of the rear seat of the vehicle and the floor of the vehicle compartment; wherein the seat lifting device 30 is used to raise the height of the rear seat under the control of the control module after the vehicle falls into water, so as to improve the evacuation height of the rear passengers.

[0046] The seat lifting device 30 is a mechanical device with height adjustment function, which can lift the passengers to the height of the window, so as to reduce the action of bending and climbing of the vulnerable groups, reduce the difficulty of evacuation, and enable them to quickly evacuate from the window.

[0047] Optionally, the seat lifting device 30 can adopt an electric push rod and load-bearing bracket combination structure, with stable lifting performance and sufficient load-bearing capacity, and the lifting process is smooth and free of impact. Specifically, the lifting stroke is 0-30 cm, the lifting speed is 5 cm / s, and the load-bearing weight is not less than 150 kg, ensuring that it is suitable for passengers of different weights, and can be accurately adjusted according to the height of the window, so that passengers can directly escape from the window without bending over or climbing. Specifically, the seat lifting device 30 is installed between the bottom bracket of the rear seat and the compartment floor, supported by four electric push rods, and controlled by a control module to lift synchronously, avoiding the inclination of the seat during lifting. When the control module determines that the passenger is in a difficult escape state, it sends a seat belt unlocking instruction at the same time, and starts the seat lifting device 30 to slowly lift the seat to a height level with the window, so that the passenger can reach the escape exit position without bending over or climbing. For example, for children who are relatively short or the elderly who have difficulty moving, after the seat is lifted, as shown in the figure, their body position is at the same level as the broken window, and they can directly escape from the window to the outside, reducing the physical exertion and operation difficulty during escape, and further improving the convenience and safety of escape for vulnerable groups. Figure 2

[0048] In an optional embodiment, the posture monitoring module further includes a rear-row assistance alarm unit, which is integrated in the vehicle infotainment system and connected with the control module; wherein the rear-row assistance alarm unit is used to send an assistance alarm to the cockpit or outside the vehicle through the vehicle infotainment system when it is detected that the rear-row passenger has not successfully escaped.

[0049] Specifically, the rear-row assistance alarm unit is a functional component for sending an assistance request signal, which is used to remind other passengers in the cockpit or rescue personnel outside the vehicle to provide help when the rear-row passenger is in difficulty.

[0050] Optionally, the rear-row assistance alarm unit is integrated in the vehicle infotainment system, and can send alarm signals through the vehicle audio, display screen and external light system in multiple channels. For example, after the alarm unit is started, the vehicle audio plays a voice prompt of "rear-row needs assistance" in a loop, the display screen can display a red and eye-catching alarm symbol, and the external turn signal or emergency light flashes synchronously, delivering the rescue demand in all directions.

[0051] The determination of whether the rear-row passenger has successfully escaped is achieved through the cooperation of the pressure sensor and the posture sensor. For example, within 10 seconds after the window is broken, if the pressure sensor still detects a passenger in the rear row and the posture sensor detects that the passenger has not moved, the control module determines that the passenger has not successfully escaped, and immediately triggers the rear-row assistance alarm unit to remind the front-row passengers to assist the vulnerable people in the rear row first, and at the same time, it is convenient for rescue personnel outside the vehicle to locate.

[0052] ​In an alternative embodiment, an openable escape passage is provided between the trunk and the cabin of the vehicle. The system provided by the present embodiment further comprises an escape cabin module 40, which is arranged at one side of the trunk of the vehicle close to the rear door.

[0053] Here, the openable escape passage refers to a passage structure connecting the cabin and the trunk, which is used to provide a backup path for passengers to enter the trunk from the cabin. When the window escape exit is blocked, the passage can be used to go to the trunk to escape using the escape cabin module 40. Specifically, the escape passage is arranged between the rear seats and the trunk, and the passage is formed by folding down the backrest of the rear seats. The opening size of the passage is not less than 60cm x 40cm, which ensures that an adult can pass through smoothly. For example, the backrest of the rear seat of the vehicle is designed as a foldable structure. The partition plate between the backrest and the trunk is provided with a removable or openable cover plate. The cover plate is in a locked state in normal times to ensure the safety of the storage of the trunk. After falling into the water, the passenger can manually fold down the seat backrest and open the cover plate to form an escape passage connecting the cabin and the trunk. The escape cabin module 40 refers to an integrated device with independent escape function. Its core function is to provide a sealed escape space for passengers who cannot escape through the window. The survival safety of the passengers in the water is ensured by providing buoyancy support and oxygen supply until they are rescued. Optionally, the escape cabin module 40 can adopt a folding design, which is normally stored in the trunk without occupying too much storage space. When triggered, it can be quickly unfolded and formed, having multiple functions such as waterproof, impact resistance, and buoyancy support. For example, the escape cabin module 40 has a rectangular cuboid structure, and the folded size is 50cm x 30cm x 25cm. It is arranged at the left side of the trunk close to the rear door. This position is convenient for passengers to quickly reach from the escape passage, and does not affect the normal storage use of the trunk. The escape cabin module 40 is arranged at one side of the trunk of the vehicle close to the rear door. In this way, the moving distance of the passengers from the cabin to the escape cabin can be shortened, and the escape cabin can be quickly popped out of the trunk after being triggered, avoiding being blocked by other objects. Here, the escape cabin module 40 can be fixed to the floor of the trunk through a slide rail. The side close to the rear door is provided with a pop-up mechanism. When the escape cabin is started, the slide rail can assist the escape cabin to slide towards the door, and the trunk cover is automatically popped open to ensure that the escape cabin enters the water smoothly. For example, a special installation area is reserved at the left side of the trunk close to the rear door. The escape cabin module 40 is fixed to the slide rail in the area by bolts. After installation, it is attached to the side wall of the trunk, which does not affect the use of other storage space of the trunk. When the passenger pulls the starting pull ring, the locking mechanism of the slide rail is unlocked, and the escape cabin moves towards the door under the action of the pop-up mechanism and is pushed out of the trunk. The combination of the escape cabin module 40 and the escape passage provides a dual path of window escape and cabin escape for vehicle water escape. When the window cannot be used due to excessive water pressure or window breaking failure, the passenger can enter the trunk through the escape passage and use the escape cabin module 40 to achieve independent escape. This design is especially suitable for extreme situations such as complete sinking of the vehicle or blockage of the window by foreign objects, further improving the coverage and reliability of the system.

[0054] In an optional embodiment, the escape cabin module 40 includes a foldable cabin, an automatic inflation buoyancy bag, and an oxygen generator. The foldable cabin is provided with an activation member, and the automatic inflation buoyancy bag and the oxygen generator are arranged in the foldable cabin. When the activation member is triggered, the foldable cabin is unfolded, the automatic inflation buoyancy bag is inflated, and the oxygen generator is started to provide oxygen.

[0055] The foldable cabin is a cabin structure with folding storage and unfolding forming functions. In a non-working state, the foldable cabin can reduce the occupied space, and in a working state, the foldable cabin can be quickly unfolded to form a sealed escape space, with impact resistance and waterproof performance to protect the passenger from water flow impact and drowning risk. Optionally, the foldable cabin can be a foldable frame structure designed with high-strength flexible materials and rigid support skeletons. The skeletons are made of lightweight aluminum alloy materials and can be folded and contracted. The cabin fabric is made of waterproof and tear-resistant nylon cloth with excellent sealing performance. For example, the unfolded foldable cabin is a cylindrical sealed cabin with a diameter of 80 cm and a length of 120 cm, which can accommodate 2 adults or 3 children. The thickness of the folded cabin is only 15 cm, which does not occupy much trunk space. The folded cabin is fixed by magic tape and buckle, and the volume is compressed to 1 / 5 of the original volume, which is convenient for storage. The automatic inflation buoyancy bag is a buoyancy component with automatic inflation function, which is used to provide buoyancy support for the foldable cabin to ensure that the cabin carries the passengers to float on the water surface and avoid sinking. Specifically, the automatic inflation buoyancy bag is built-in around the foldable cabin and is made of high-strength waterproof cloth. After inflation, it forms a ring-shaped buoyancy structure with sufficient buoyancy. Specifically, the automatic inflation buoyancy bag is built-in with a high-pressure gas storage device and a trigger mechanism, which is linked with the unfolding mechanism of the foldable cabin. When the cabin is unfolded, the inflation is triggered synchronously, and the inflation time is not more than 1 second. The buoyancy can bear a weight of not less than 200 kg. For example, the automatic inflation buoyancy bag is arranged at the top and both sides of the foldable cabin, adopts a double-layer air bag structure, and is built-in with a CO2 high-pressure cylinder. When the activation member is triggered, the cylinder valve is automatically opened, the gas is quickly injected into the air bag, the cabin is quickly floated and kept in a stable floating posture. The oxygen generator is a device with oxygen generation function. Its core function is to provide continuous oxygen supply for passengers in the folding cabin to avoid suffocation caused by cabin sealing or underwater oxygen deficiency. Specifically, the oxygen generator can use chemical oxygen generation technology to slowly release oxygen through chemical reaction, without external power supply or gas source, with long service life and high safety. For example, the oxygen generator is internally provided with a mixed chemical agent of sodium chlorate and iron. When it comes into contact with water, it will react chemically to continuously release oxygen and absorb carbon dioxide in the cabin. After starting, it can provide sufficient oxygen for 15 minutes to meet the breathing needs of two passengers in the closed cabin. Here, the starting piece refers to a manual operating component with the functions of triggering the unfolding, inflation and oxygen supply of the escape cabin. It is used for passengers to quickly start the unfolding, inflation and oxygen supply functions of the cabin. Its core function is to provide a simple and intuitive triggering method for passengers, so that they can operate quickly even in a panic state. Specifically, the starting piece can adopt a pull ring design and have anti-misoperation protection. The surface of the pull ring is provided with anti-slip patterns to facilitate passengers to hold it in water or in an emergency. For example, the starting piece can be a red ring-shaped pull ring arranged on the outer surface of the folding cabin. An insurance pin is arranged below the pull ring. The insurance pin is in an inserted state at ordinary times to prevent misoperation. When in use, the passenger only needs to pull out the insurance pin and pull the pull ring to start the linkage of the pull ring, the unfolding mechanism of the cabin, the inflation device and the oxygen generator. Only the pull ring needs to be pulled to start multiple functions simultaneously, without complex operation. Optionally, the working process of the escape cabin module 40 is as follows: after the passengers enter the trunk through the escape channel, the insurance pin of the starting piece is pulled out, the pull ring is pulled, the support skeleton of the folding cabin is automatically unfolded under the action of the spring mechanism, the gas cylinder valve of the automatic inflation buoyancy bag is opened and quickly inflated, the oxygen generator starts to release oxygen after coming into contact with the water in the cabin, the automatic pop-up mechanism of the trunk cover is triggered synchronously (the trunk lock is unlocked and popped out by the control module), and the passengers enter the unfolded cabin. The cabin floats to the water surface under the action of the buoyancy. For example, when the vehicle sinks and the windows are blocked by underwater debris and cannot be broken, the rear passengers can lower the backrest of the rear seat, open the cover plate of the escape channel, enter the trunk, and quickly trigger the escape cabin module 40. The unfolded cabin can accommodate two passengers and float in the water to wait for rescue, effectively solving the escape problem in extreme situations.

[0056] In actual application, when the vehicle sinks and the door and window escape path is blocked, the passengers can enter the trunk through the escape channel formed by folding the rear seat, find the folding escape cabin near the left rear door, and pull the red starting pull ring. At this time, the folding cabin is quickly unfolded, the automatic inflation buoyancy bag is instantly inflated to form a buoyancy structure, the oxygen generator is started synchronously to supply oxygen, the trunk cover is automatically popped up, the passengers enter the cabin, and the cabin floats to the water surface to wait for rescue.

[0057] In an alternative embodiment, the folding cabin is made of transparent and impact-resistant material, and the surface of the folding cabin is printed with a reflective strip and a rescue mark; the escape cabin module 40 further comprises an audible and visual alarm, and the audible and visual alarm is arranged in the folding cabin.

[0058] Here, the folding cabin is made of transparent and impact-resistant material, which is a high-molecular material with light transmission and impact resistance, capable of ensuring that the passengers inside the cabin can observe the external environment, while resisting the impact of water debris and protecting the safety of the passengers. For example, the main material of the folding cabin is a high-strength transparent PC (polycarbonate) plate with a thickness of 5 mm, which has the characteristics of high impact resistance, high light transmission, and water resistance. For example, the impact resistance of the transparent PC plate is 200 times that of ordinary glass, and the light transmission rate is more than 90%. Even if it is hit by a stone or other hard object underwater, it will not break, and at the same time, passengers can observe the external rescue situation through the transparent cabin, reducing panic. Here, the reflective strip refers to a marking component with light reflection function, which can produce strong reflection under light irradiation, facilitating rescue personnel to quickly locate the position of the escape cabin during the day or at night. Specifically, the reflective strip can be made of high-brightness micro-prism reflective material, with a width of 5 cm, evenly pasted along the circumference of the folding cabin, and the pasting position avoids the observation area of the cabin, without affecting the passenger's field of vision. For example, the reflective strip is pasted at the intersection of the top and side of the folding cabin, a total of 4 strips, with an angle of 90° between adjacent reflective strips. When the rescue personnel use a flashlight or the searchlight of the rescue ship to irradiate, the reflective strip can produce strong reflected light, which can be quickly identified even in complex water areas. Here, the rescue mark can be a graphic mark with clear rescue prompt function, which can convey the information that there are trapped persons in the cabin to the rescue personnel, while indicating the safety area of the cabin. For example, the rescue mark can be printed with red waterproof ink, including the text mark "Someone is trapped" and the internationally recognized distress signal mark (SOS), and the printing position is located on the front and back of the folding cabin, with moderate font size to ensure visibility at a distance. For example, the text of the rescue mark is designed with bold black font, with a font height of 10 cm, and the SOS mark has a size of 20 cm x 20 cm, printed in the center of the front of the cabin. Even in foggy or insufficient light environments, rescue personnel can quickly identify the rescue needs of the cabin. Here, the sound and light alarm refers to a warning device with sound alarm and light alarm functions, which can actively send high-frequency alarm signals to improve the probability of being discovered in complex water areas, such as night, fog, and open water. Specifically, the sound and light alarm can be built-in high-energy lithium battery (waterproof design), with two alarm modes: high-frequency buzzer alarm and red light flashing alarm, with alarm duration not less than 2 hours, ensuring sufficient rescue response time. For example, the sound and light alarm is installed on the inside top of the folding cabin, isolated from the outside by a sealing cover plate. When the escape cabin module 40 is activated, the sound and light alarm is automatically activated, emitting continuous buzzer sound with a frequency of 2kHz, with a volume not less than 100dB, and emitting red flashing light with a flashing frequency of 3 times per second. The buzzer sound and flashing light work synchronously, and even rescue ships several kilometers away can detect them. Alternatively, the power supply of the sound and light alarm can be provided by the built-in lithium battery of the escape cabin module 40, with a capacity of 5000mAh, only powering the sound and light alarm and the trigger mechanism of the oxygen generator, ensuring the continuous and stable alarm function. For example, when the escape cabin module 40 is activated, the lithium battery automatically powers the sound and light alarm, the buzzer sound is emitted through the waterproof speaker on the top of the cabin, and the red light is emitted through the transparent window on the top of the cabin. The two alarm methods work together to greatly improve the probability of being rescued in harsh environments.

[0059] In this way, through the multiple designs of transparent protection, reflective positioning, and active alarm, the passengers in the escape cabin are provided with all-round safety protection, further improving the success rate of rescue in extreme situations.

[0060] The embodiments of the present application greatly improve the success rate of personnel escape after the vehicle falls into water through the design of intelligent trigger window breaking, buoyancy auxiliary positioning, attitude monitoring and warning, and independent escape cabin protection, providing all-round and multi-level escape protection.

[0061] Finally, it should be noted that the above-described embodiments are merely specific implementations of the present application, which are used to illustrate the technical solutions of the present application, but not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can make modifications or easily think of changes to the technical solutions described in the foregoing embodiments within the technical scope disclosed by the present application, or make equivalent replacements to some technical features.
