Description

Technical Field

[0001] This invention relates to the field of automotive in-vehicle emergency safety equipment technology, specifically an adaptive graded window-breaking rescue control method for vehicle submersion and car accident scenarios. Background Technology

[0002] With the continuous increase in the number of motor vehicles, vehicle submersion and traffic accidents have become frequent types of safety incidents. Existing vehicle-mounted escape devices have the following technical shortcomings: Insufficient power supply reliability: Traditional electronic window breakers rely on vehicle power. When a vehicle falls into water, the circuit is prone to short circuit and power failure, causing the equipment to malfunction and fail to work properly. The false triggering rate is high. Most existing products use a single water level sensor, which is prone to false triggering in scenarios such as car washing, wading through water in heavy rain, and rain showers, which can break car windows and cause unnecessary property damage. The lack of anti-sinking design means that a large amount of water entering after the window is broken will accelerate the sinking speed of the vehicle. Existing technology does not consider a graded delayed triggering mechanism, making it impossible to strike a balance between delaying sinking and timely escape. Poor adaptability to extreme working conditions. Under extreme working conditions such as vehicle rollover, roof falling into water first, and the whole vehicle overturning, the vehicle body posture is complex, conventional sensors fail to recognize it, and after overturning, the interior of the vehicle forms an inverted space, which greatly increases the probability of people being injured or losing consciousness. Existing technologies cannot effectively deal with such scenarios. Lacking a coma rescue function, in the event of a serious car accident, the vehicle body is deformed and the doors are jammed, and the driver and passengers often fall into a coma due to the impact and are unable to escape on their own; the existing escape devices only focus on the self-rescue of people inside the vehicle and have not designed automatic rescue channels for scenarios of disability, making it difficult for external rescuers to enter quickly and delaying the best rescue opportunity. Secondary injury risk: After the window breaks, shards of glass fly everywhere without protection, which can easily cut the face, eyes, and hands of the driver and passengers, aggravating their injuries. Traditional window-breaking rescue control methods suffer from poor environmental adaptability, poor waterproofing, susceptibility to mud and sand accumulation, and a tendency to jam in low-temperature environments. They also have high standby power consumption requiring frequent charging and maintenance, and often involve drilling for installation, damaging the original vehicle structure and lacking versatility. Therefore, this invention provides an adaptive, tiered window-breaking rescue control method for vehicle submersion and accident scenarios. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an adaptive graded window-breaking rescue control method for vehicle submersion and traffic accident scenarios, in order to solve the aforementioned problems.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: an adaptive graded window breaking rescue control method for vehicle submersion and car accident scenarios, wherein the adaptive graded window breaking rescue control method is based on an automatic window breaking escape rescue device for both vehicle submersion and car accident scenarios, wherein the device includes a main control sensing module, a lithium battery, an instantaneous impact window breaking mechanism, a hidden manual trigger button, a flexible anti-glass splash buffer curtain, and a waterproof shell. The main control sensing module is connected to an external detection sensor assembly. The main control sensing module has a dual start-up mode: fully automatic sensing trigger and manual button trigger inside the vehicle. The lithium battery provides independent power for the device. The instantaneous impact window breaking mechanism targets the weak stress points at the four corners of the window for precise impact, achieving rapid window breaking. The flexible anti-glass shard buffer curtain is a retractable flexible mesh structure. The waterproof shell is located on the outside of the main control sensing module to protect the components, and the hidden manual trigger button is located inside the waterproof shell.

[0005] Preferably, the detection sensor assembly includes a water level sensor, a tilt sensor, a collision sensor, and a human body state recognition module; wherein, the water level sensor is deployed at multiple points at different locations on the vehicle to detect water ingress at different locations; the tilt sensor achieves 0-180° full-angle detection to identify various vehicle postures, including normal posture, rollover, overturned, roof-first water ingress, and overturned posture; the collision sensor is used to detect severe vehicle impact signals; and the human body state recognition module continuously detects the micro-movements and activity states of the occupants inside the vehicle. The human body state recognition module has a built-in delay judgment program to distinguish between normal sitting, short rest, and unconscious / disabled states, avoiding accidental activation in non-accident scenarios.

[0006] Preferably, the detection sensor assembly detects the following conditions: falling into water and vehicle accident rescue. The falling into water condition includes a regular vehicle falling into water and the roof falling into water first, and the whole vehicle overturning / rolling over. The vehicle accident rescue condition includes a vehicle collision, a jammed door, and a person being unconscious and trapped.

[0007] Preferably, the triggering logics for the water-falling condition and the vehicle accident rescue condition are independent of each other but work together.

[0008] Preferably, the instant impact window breaking mechanism uses a high-hardness alloy striker combined with a powerful spring or a flameless ejection structure to achieve instant impact window breaking.

[0009] Preferably, the flexible glass-breaking buffer curtain is normally stored inside the device, and pops out partially when the window breaks, covering only the inner area of ​​the glass to block the shards; it is made of thin, flexible nylon material.

[0010] Preferably, the lithium battery is a rechargeable lithium battery that operates in a microampere-level ultra-low power sleep mode under normal conditions, and has a standby time of ≥2 years on a single full charge.

[0011] Preferably, the waterproof outer shell adopts a fully sealed waterproof potting structure, and the waterproof outer shell is a non-drilling adhesive structure, which is fixed to the inside of the vehicle window.

[0012] An adaptive hierarchical window-breaking rescue control method for vehicle submersion and traffic accident scenarios includes the following steps: S1. Independent power supply and normal sleep mode: The built-in backup lithium battery provides independent power to the device, which does not rely on the vehicle's on-board battery. It can still standby and trigger work normally when the vehicle is submerged in water and short-circuited or the entire vehicle is powered off. The device is in a micro-ampere-level ultra-low power sleep state under normal conditions, with the built-in lithium battery providing independent power. Long-term standby does not require frequent charging and maintenance. S2. Adaptive Tiered Window Breaking in Water Scenarios: Employing both water level and tilt angle as criteria, a true water-falling accident is determined only when the water level data detected by multi-point water level sensors and the vehicle posture data detected by the full-angle tilt angle sensor simultaneously reach a preset danger threshold. A tiered delayed triggering mechanism is implemented: When the vehicle has just entered the water, only the chassis or roof is submerged, the vehicle posture is stable, or the tilt angle has not reached the threshold, the device delays window breaking, utilizing the sealed air chamber inside the vehicle to slow the vehicle's descent. When both the water level and tilt angle reach the danger threshold, the window breaking mechanism is activated immediately. When sensors detect that the top of the vehicle has fallen into the water first, and the entire vehicle is upside down, the system prioritizes controlling the lower-position windows to break, utilizing the inverted air chamber to enhance escape and rescue safety. S3. Car Accident Scene Unconscious Rescue Window Breaking: When the collision sensor detects a severe impact signal and the vehicle door is locked or deformed and jammed, and the human body state recognition module determines after a preset delay that the driver and passengers have not moved their limbs for a long time and have lost the ability to move independently, the main control sensing module automatically drives the window breaking mechanism to break the window and open a channel for external rescue; the human body state recognition module has a built-in delay judgment program to distinguish between normal sitting, short rest and unconscious state, avoiding accidental activation in non-accident scenarios; S4. Dual Start-up Protection: The device features a dual start-up mode with fully automatic sensor triggering and a hidden manual button triggering inside the vehicle. Regardless of whether the automatic sensor system is working, occupants can directly press the hidden manual triggering button to forcefully start the window-breaking mechanism with one click, enabling emergency self-rescue. S5. Anti-splash and escape route protection: The window breaking point is aimed at the four weak stress points of the window for targeted impact to achieve rapid window breaking; the matching flexible anti-splash buffer curtain is a retractable flexible soft net structure that provides shielding and protection when broken glass splashes. The soft net can be deformed by external force without blocking the window passage or affecting personnel entry and exit. S6. Fully Sealed and Environmentally Adaptable: The whole machine adopts a fully sealed waterproof potting structure, which has the properties of moisture-proof, waterproof, anti-siltation, and anti-low temperature freezing, and can be immersed in water for a long time to work normally.

[0013] Beneficial effects Compared with the prior art, the present invention has the following advantages: Powered by an independent lithium battery, it effectively solves the problem of vehicle circuit failure due to water immersion, significantly improving reliability and ensuring normal operation of the equipment under extreme conditions, with strong power supply safety. It is compatible with three major accident scenarios: common water submersion, overturned water submersion, and vehicle entrapment, offering versatility and wide applicability. Hierarchical delay logic slows down the descent, and a flexible mesh prevents glass scratches, eliminating multiple safety hazards and improving escape safety. Multiple sensor linkages and delay judgments effectively prevent false triggering in scenarios such as rain, wading, and normal rest, reducing the error rate and ensuring accurate recognition. It supports autonomous escape for occupants and can automatically open windows when someone is unconscious, assisting external rescue efforts and improving rescue efficiency. It supports 0–180° full-angle attitude recognition, accurately responding to vehicle rollovers, roof-first water entry, and overturned situations, prioritizing the opening of low-position windows to improve survival rates in extreme scenarios. It features drill-free adhesive installation, causing no damage to the vehicle, ultra-low power consumption, waterproofing, durability, and long-term maintenance-free operation, reducing operating costs and facilitating easy installation and maintenance.

[0014] Figure 1 This is a system architecture diagram of the present invention; Figure 2 This is a flowchart of the process of the present invention. Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1An adaptive graded window-breaking rescue control method for vehicle submersion and car accident scenarios is presented. This method is based on a dual-purpose automatic window-breaking escape and rescue device for both submersion and accidents. The device includes a main control sensing module, a lithium battery, an instantaneous impact window-breaking mechanism, a hidden manual trigger button, a flexible anti-glass-splash buffer curtain, and a waterproof shell. The main control sensing module is externally connected to a sensor assembly and features both fully automatic sensor triggering and in-vehicle manual button triggering modes. The lithium battery provides independent power to the device, independent of the vehicle's onboard battery, and can still operate normally in standby and triggering states even when the vehicle is submerged, short-circuited, or experiencing a power outage. The instantaneous impact window-breaking mechanism targets the weakest points at the four corners of the window for precise impact, achieving rapid... The device features a quick-break window mechanism and a flexible, retractable soft mesh buffer curtain. This mesh acts as a shield when broken glass shards fly, and can be deformed by external force without obstructing the window passage or hindering entry and exit. A waterproof outer shell is located on the outside of the main control sensor module to protect the components, while a hidden manual trigger button is located inside. This waterproof shell protects the internal components, ensuring performance and lifespan. The hidden manual trigger button effectively prevents accidental activation during normal vehicle operation. Furthermore, in the event of sensor malfunction or other abnormalities in the fully automatic sensing mode, passengers can manually initiate the window-breaking process, adding an extra layer of reliability to the device.

[0017] Specifically, the detection sensor assembly includes a water level sensor, a tilt sensor, a collision sensor, and a human body state recognition module. The water level sensor is deployed at multiple points at different locations on the vehicle to detect water ingress at various locations. The tilt sensor achieves 0–180° omnidirectional detection, identifying various vehicle postures including normal, rollover, overturned, roof-first water ingress, and overturned. The collision sensor detects severe impact signals. The human body state recognition module continuously monitors the subtle movements and activity states of occupants, incorporating a built-in delay judgment program to distinguish between normal sitting, brief rest, and unconscious / disabled states, preventing accidental activation in non-accident scenarios. Through the effective coordination of these sensors, a comprehensive perception of accident scenarios can be achieved, accurately identifying the accident type, severity, and occupant status, avoiding false triggering or missed triggering caused by single sensor detection bias, and providing accurate data support for subsequent adaptive graded triggering decisions.

[0018] Specifically, the detection sensor components detect conditions including water-falling conditions and vehicle accident rescue conditions. Water-falling conditions include regular vehicle falling into water, vehicle roof falling into water first, and the entire vehicle overturning / rolling over. Vehicle accident rescue conditions include vehicle collision, vehicle door jamming, and unconscious and trapped personnel. By classifying the conditions according to different situations, differentiated triggering decisions can be made, ensuring rapid response in extremely dangerous scenarios while avoiding interference from accidental window breaking in normal driving or low-risk scenarios.

[0019] Specifically, the triggering logics for the water-falling scenario and the car accident rescue scenario are independent of each other but work together; if the unconsciousness of the driver and passengers is detected simultaneously in the water-falling scenario, the device will normally perform the window-breaking action, taking into account both escape and external rescue.

[0020] Specifically, the instant impact window breaking mechanism uses a high-hardness alloy striker combined with a powerful spring or a flameless ejection structure to achieve instant impact window breaking; thus, it can output a sufficiently strong instantaneous impact force without relying on external power or generating open flame safety hazards, and can efficiently break the high-strength tempered glass commonly used in vehicles, meeting the window breaking needs for emergency escape.

[0021] Specifically, the flexible glass-breaking buffer curtain is normally stored inside the device, but it pops out partially when the window breaks, covering only the inner area of ​​the glass to block the debris. It is made of thin, flexible nylon material, without a rigid frame or taut ropes, so it will not entangle people's hands or feet, and will not affect personnel entry and exit or rescue operations, ensuring its effectiveness.

[0022] Specifically, the lithium battery is a rechargeable lithium battery that operates in a microampere-level ultra-low power sleep mode under normal conditions, and can last for ≥2 years on a single full charge; thus ensuring long-term use performance.

[0023] Specifically, the waterproof shell adopts a fully sealed waterproof potting structure, and the waterproof shell is a non-drilling adhesive structure that is fixed to the inside of the car window. This structure and adhesive method enable the device to meet the waterproof requirements after the vehicle falls into water, while not causing drilling damage to the original interior structure or body sheet metal of the vehicle. There is no need to modify the original vehicle wiring and sealing structure, and the installation process is simple and quick.

[0024] Working principle: During normal vehicle operation, the device maintains a microampere-level ultra-low power sleep state. Each detection sensor collects vehicle status, environmental status, and occupant status data at set intervals and transmits them to the main control sensing module. The main control sensing module performs data calculation and condition determination in real time, without consuming additional power or interfering with normal vehicle operation.

[0025] In the event of an accident, multiple sensors will simultaneously transmit data on water level, tilt angle, collision, and personnel activity status to the main control sensing module. The main control sensing module, combined with preset adaptive grading judgment logic, identifies the accident conditions and danger levels: if the conditions for breaking the window are met, a drive signal will be immediately output to activate the instantaneous impact window breaking mechanism, driving a high-hardness alloy striker to complete an instantaneous impact on the weakest point of the window. At the same time, a flexible anti-glass shard buffer curtain will be triggered to pop out and cover the inside of the glass, achieving rapid window breaking while preventing glass shards from flying and avoiding injuries to personnel. If the fully automatic sensing mode cannot be triggered normally due to sensor malfunction or other abnormalities, conscious occupants can open the waterproof shell and operate the hidden manual trigger button to manually start the window breaking process.

[0026] Regardless of whether the vehicle experiences a short circuit or power outage after falling into water, the independently powered lithium battery can stably output power to ensure the normal execution of the entire window-breaking process, ultimately quickly opening an escape route. This facilitates self-rescue and escape for those trapped inside the vehicle and also provides convenience for subsequent external rescue operations.

[0027] Example 1: A conventional vehicle falls into water (entering the water in its normal posture) As soon as the vehicle entered the water, only the chassis was slightly submerged. The water level sensor and tilt sensor did not reach the danger threshold. The graded delay logic was activated, and the device delayed breaking the window, using the sealed air cavity inside the vehicle to slow down the vehicle's sinking speed. As the water level continued to rise and the vehicle tilted, both the water level and tilt angle data simultaneously reached the preset danger threshold, and the main control sensing module determined that it was a formal water-falling danger. The main control sensor module immediately drives the instantaneous impact window-breaking mechanism to quickly shatter the glass at the four weak points of the window; at the same time, a flexible anti-glass shard buffer curtain pops out to catch the flying glass shards and prevent people from being cut. After the window is broken, the internal and external air pressures are balanced, completely releasing the water pressure from locking the doors and windows, allowing passengers to climb out directly through the window to escape; the flexible mesh is soft and can be easily squeezed open by the human body without obstructing passage. If the device detects that the driver or passengers have been inactive for an extended period and are unconscious when the vehicle or passenger falls into the water, it will still break the window as usual, and the window will be used as an external rescue channel.

[0028] Example 2: The roof falls into the water first, and the whole vehicle overturns / rolls over (extreme water-falling condition) The vehicle overturned and the top entered the water first. Multi-point water level sensors quickly detected the water ingress signal, and the all-angle tilt sensor identified the vehicle's overturned posture. When the water level does not reach the threshold in the initial stage of water entry, the device maintains a delay to prevent the window from breaking, and an inverted air cavity is formed inside the vehicle, which effectively slows down the sinking of the entire vehicle. When the water level continues to rise and both judgment conditions are triggered, the system will prioritize the lower window to perform the window breaking operation (air retention area). After the window is broken, the water pressure inside and outside is balanced. The low-positioned window facilitates personnel evacuation and external rescue. The buffer mesh plays its normal role in preventing glass from flying. There is no obstruction throughout the process.

[0029] Example 3: Car accident, door jammed, occupants unconscious and trapped. The vehicle was involved in a severe collision. The collision sensors captured the impact signal and detected that the doors were deformed and locked, making them unable to be opened. The human body status recognition module continuously monitors the status of the people inside the vehicle. After a preset delay, it determines whether the driver or passenger has been without limb movement for a long time and has lost the ability to move independently due to unconsciousness caused by the impact. The main control sensor module automatically activates the instantaneous impact window-breaking mechanism to shatter the car window and quickly open a rescue channel, allowing external rescuers to enter the vehicle through the window to carry out rescue operations. When a person is briefly still, resting normally, or engaging in normal activities inside the vehicle, the delayed judgment logic will not trigger the window breaking mechanism, thus preventing accidental operation.

[0030] Please see Figure 2 An adaptive hierarchical window-breaking rescue control method for vehicle submersion and traffic accident scenarios includes the following steps: S1. Independent power supply and normal sleep mode: The built-in backup lithium battery provides independent power to the device, which does not rely on the vehicle's on-board battery. It can still standby and trigger work normally when the vehicle is submerged in water and short-circuited or the entire vehicle is powered off. The device is in a micro-ampere-level ultra-low power sleep state under normal conditions, with the built-in lithium battery providing independent power. Long-term standby does not require frequent charging and maintenance. S2. Adaptive Tiered Window Breaking in Water Scenarios: Employing both water level and tilt angle as criteria, a true water-falling accident is determined only when the water level data detected by multi-point water level sensors and the vehicle posture data detected by the full-angle tilt angle sensor simultaneously reach a preset danger threshold. A tiered delayed triggering mechanism is implemented: When the vehicle has just entered the water, only the chassis or roof is submerged, the vehicle posture is stable, or the tilt angle has not reached the threshold, the device delays window breaking, utilizing the sealed air chamber inside the vehicle to slow the vehicle's descent. When both the water level and tilt angle reach the danger threshold, the window breaking mechanism is activated immediately. When sensors detect that the top of the vehicle has fallen into the water first, and the entire vehicle is upside down, the system prioritizes controlling the lower-position windows to break, utilizing the inverted air chamber to enhance escape and rescue safety.

Anti-splash and escape route protection: The window breaking point is aimed at the four weak stress points of the window for targeted impact to achieve rapid window breaking; the matching flexible anti-splash buffer curtain is a retractable flexible soft net structure that provides shielding and protection when broken glass splashes. The soft net can be deformed by external force without blocking the window passage or affecting personnel entry and exit. S6.
