Description

Technical Field

[0001] This application relates to the field of vehicle escape system technology, and in particular to a window breaking control system and vehicle. Background Technology

[0002] With the widespread use of vehicles, vehicle accidents are becoming increasingly common. These accidents are characterized by their suddenness, frequency, and wide impact. Accidents causing severe personal injury can have a significant impact on the safety of passengers and their property, resulting in a strong negative social impact. Therefore, major automobile manufacturers and parts suppliers are continuously researching and optimizing vehicle escape systems. Vehicle window-breaking systems are one common type of vehicle escape system, used to quickly break windows, open escape routes, and buy precious time for occupants to escape.

[0003] Currently, most vehicle window breaking systems explode immediately upon triggering, and the fragments from the broken window can easily cause serious injury to people inside and outside the vehicle who are unable to dodge in time. Utility Model Content

[0004] This application at least partially solves the technical problem that fragments from a broken car window can easily cause serious injury to people inside and outside the vehicle who are unable to dodge in time.

[0005] Therefore, this application aims to provide a window breaking control system and vehicle, which breaks the vehicle window glass in two stages through a first detonation module and a second detonation module. The slight explosion of the first detonation module serves as a warning, giving people inside and outside the vehicle time to move away from the window and reducing the possibility of injury to people inside and outside the vehicle caused by the flying glass fragments when the second detonation module is triggered.

[0006] To achieve the above objectives, in a first aspect, this application provides a window breaking control system, comprising: a central control unit with a timing module, an input unit, and a window breaking unit; the input unit includes, electrically connected to the central control unit, an accident sensing unit for sensing whether the vehicle is in an abnormal state, a door monitoring unit for monitoring the opening and closing status of the doors, an in-vehicle detection unit for detecting the status of the occupants, and a manually triggered detonation switch; The vehicle window blasting unit includes a first detonation module and a second detonation module that are electrically connected to the main control unit; both the first detonation module and the second detonation module are used to blast the vehicle window glass; after the first detonation module detonates, the vehicle window glass remains intact but develops cracks; after the second detonation module detonates, the vehicle window glass shatters completely.

[0007] The technical solution involves breaking the car window in two stages. The first, minor explosion serves as a warning, giving people inside and outside the vehicle time to move away from the window and reducing the possibility of injury from the flying glass shards during the second explosion.

[0008] In some embodiments of this application, the window breaking control system further includes a side curtain triggering unit that is electrically connected to the main control unit.

[0009] In the technical solution, by deploying side curtain airbags to block the space between the occupants and the windows, the possibility of injury to the occupants from flying glass shards during an explosion can be reduced, as can the possibility of occupants being injured by flying glass shards due to limited space for maneuver.

[0010] In some embodiments of this application, the window breaking control system further includes a door lock opening and closing unit electrically connected to the main control unit, the door lock opening and closing unit being used to control the opening and closing of the vehicle door lock.

[0011] In the technical solution, for serious land accidents, the vehicle doors can be automatically unlocked when the occupants are mobile, so as to minimize damage to the vehicle and avoid unnecessary property loss while ensuring rapid escape.

[0012] In some embodiments of this application, the accident sensing unit includes: a collision sensing unit that senses the intensity of a vehicle collision, a water immersion sensing unit that senses the degree of immersion of a vehicle, and a fire sensing unit that senses whether a vehicle is on fire, all of which are electrically connected to the central control unit.

[0013] The technical solution categorizes accidents into three types: collision, fire, and falling into water. This allows the central control unit to determine whether to break a window based on different conditions for each type of accident.

[0014] In some embodiments of this application, the window breaking control system further includes a countdown reminder unit electrically connected to the main control unit, the countdown reminder unit emitting sound and / or light representing a countdown.

[0015] In this technical solution, occupants inside and outside the vehicle can predict the timing of the window explosion based on the sound and / or light emitted by the countdown reminder unit, allowing them to prepare for escape or rescue. In the event of a drowning accident, this design helps increase the survival rate of occupants.

[0016] In some embodiments of this application, the window breaking control system further includes an indicator module electrically connected to the main control unit; the indicator module issues an indicator signal to guide personnel to open the vehicle door and / or trigger the detonation switch; the indicator signal is a voice signal and / or a light signal.

[0017] In the technical solution, personnel can clearly and explicitly trigger the detonation switch based on voice signals, and personnel can clearly and explicitly determine the location of the detonation switch based on light signals.

[0018] In some embodiments of this application, multiple first detonation modules are evenly arranged around the vehicle window, and multiple second detonation modules are evenly arranged around the vehicle window; both the first and second detonation modules are equipped with a detonator and a combustible explosive substance electrically connected to the main control unit, and the combustible explosive substance in the first detonation module is less than the combustible explosive substance in the second detonation module.

[0019] In this technical solution, the shock wave generated by the detonation of the first detonation module propagates at extremely high speed into the glass, creating strong tensile stress and causing microcracks within the glass. Due to the low energy and uniform distribution, these cracks connect without causing the glass to disintegrate, and the glass remains largely intact. The shock wave generated by the detonation of the first detonation module has even higher energy, rapidly expanding and connecting existing microcracks while simultaneously generating new cracks. These cracks rapidly expand and intersect within the glass, ultimately causing the glass to shatter into small pieces, completely breaking the car window.

[0020] In some embodiments of this application, the in-vehicle detection unit includes multiple in-vehicle cameras with different perspectives for monitoring the in-vehicle scene, and an image analysis module electrically connected to all the in-vehicle cameras; both the in-vehicle cameras and the image analysis module are electrically connected to the central control unit.

[0021] In the technical solution, the image analysis module determines the category and activity of occupants based on multiple in-vehicle cameras. Age recognition is primarily achieved by analyzing human features in the images. Mobility assessment is mainly determined by tracking key points of the head and limbs, as well as the direction of gaze, to comprehensively evaluate the mobility status of the occupants.

[0022] In some embodiments of this application, the detonation switch is provided both inside and outside the vehicle.

[0023] In the technical solution, the detonation switch is installed both inside and outside the vehicle to facilitate rescuers outside the vehicle in rescuing people inside the vehicle, thereby improving rescue efficiency.

[0024] Secondly, this application provides a vehicle whose body is equipped with the window breaking control system described in any of the above claims.

[0025] The technical solution provides a vehicle with a warning system for window breakage. By slightly breaking the window, it buys time for people inside and outside the vehicle to move away from the window, reducing the possibility of injury to people inside and outside the vehicle from the flying glass shards from a second breakage.

[0026] The beneficial effects of the window breaking control system and vehicle provided in this application include at least the following: 1. This application proposes a window-breaking control system and vehicle, which breaks the vehicle window glass in two stages through a first detonation module and a second detonation module. The slight explosion of the first detonation module serves as a warning, giving occupants inside and outside the vehicle time to move away from the window and reducing the possibility of injury to occupants from flying glass shards when the second detonation module is triggered. This application at least partially solves the technical problem that shards from a broken window can easily cause serious injury to occupants inside and outside the vehicle who are unable to react in time.

[0027] 2. By deploying side curtain airbags and placing them between the occupants and the windows, the possibility of injury to occupants from flying glass shards during an explosion can be reduced, as can the possibility of occupants being injured by flying glass shards due to limited space for maneuver.

[0028] 3. For ground accidents, such as fires and collisions, where the difficulty of escaping is relatively small, the vehicle doors can be automatically unlocked to open an escape route for the occupants without triggering the window breaking unit and the side curtain airbags, thus avoiding unnecessary property damage.

[0029] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0032] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. It should be noted that with the widespread use of vehicles, vehicle accidents are also increasing. These accidents are characterized by their suddenness, frequency, and wide impact. Once an accident results in serious personal injury, it will have a significant impact on the safety of passengers' lives and property, and will have a strong negative social impact. Therefore, major automobile manufacturers and parts manufacturers are constantly researching and developing vehicle escape systems, continuously optimizing them. Vehicle window breaking systems are one of the common vehicle escape systems. They are used to quickly break car windows, open escape routes, and buy precious time for occupants to escape.

[0033] In existing technologies, most vehicle window breaking systems explode immediately upon triggering, and the fragments from the broken window can easily cause serious injury to people inside and outside the vehicle who are unable to dodge in time.

[0034] Based on this, this application proposes a window-breaking control system and vehicle. The system breaks the vehicle window glass in two stages: a first detonation module and a second detonation module. The slight breakage of the first detonation module serves as a warning, giving occupants inside and outside the vehicle time to move away from the window and reducing the possibility of injury from flying glass shards when the second detonation module is triggered. This application at least partially solves the technical problem that shards from a broken window can easily cause serious injury to occupants inside and outside the vehicle who are unable to react in time.

[0035] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0036] like Figures 1-3 As shown in an illustrative embodiment of the window breaking control system and vehicle of this application, the window breaking control system includes: a central control unit 1 with a timing module, an input unit, and a window breaking unit; the input unit includes an accident sensing unit that senses whether the vehicle is in an abnormal state, a door monitoring unit 4 that monitors the opening and closing status of the doors, an in-vehicle detection unit that detects the status of the people inside the vehicle, and a manually triggered detonation switch 6, which is electrically connected to the central control unit 1. The vehicle window blasting unit includes a first detonation module 21 and a second detonation module 22 that are electrically connected to the main control unit 1; both the first detonation module 21 and the second detonation module 22 are used to blast the vehicle window glass; after the first detonation module 21 detonates, the vehicle window glass remains intact but develops cracks; after the second detonation module 22 detonates, the vehicle window glass shatters completely.

[0037] The main control unit 1 determines whether it is necessary to break the window based on the signal from the input unit. When the main control unit 1 determines that it is necessary to break the window, it controls the window breaking unit to perform the first explosion so that the window glass remains intact but develops cracks. After the first explosion, a timer is started, and after a preset time, the window breaking unit is controlled to perform the second explosion to break the window glass.

[0038] In the technical solution, the vehicle window glass is broken in two stages by the first detonation module 21 and the second detonation module 22. The slight explosion of the first detonation module 21 serves as a warning, giving people inside and outside the vehicle time to move away from the window and reducing the possibility of injury to people inside and outside the vehicle caused by the flying glass fragments when the second detonation module 22 is triggered.

[0039] Furthermore, the interval between the first explosion triggered by the first detonation module 21 and the second explosion triggered by the second detonation module 22 should be within 3 to 10 seconds, in order to allow for reaction time and preparation time for personnel inside and outside the vehicle. On this basis, the escape route should be opened in a timely manner so that the personnel inside the vehicle can be evacuated from the accident vehicle within the golden time.

[0040] In some embodiments of this application, the central control unit 1 classifies the vehicle status into severe land accidents, water accidents, and minor accidents based on the signals from the accident perception unit; in the case of a minor accident, it is determined that no window needs to be broken; in the case of water accidents, it is determined whether a window needs to be broken based on the detonation switch 6; in the case of severe land accidents, it is determined whether a window needs to be broken based on the signals from the door monitoring unit 4, the in-vehicle detection unit, and the detonation switch 6; severe land accidents include severe collisions and fires.

[0041] The technical solution employs different conditions to determine whether breaking a window is necessary for different accident types. For collisions posing minimal threat to personal safety, breaking a window is unnecessary to minimize damage to the vehicle and avoid unnecessary property loss. For serious land accidents and drowning accidents, which pose a significant threat to personal safety, different preconditions for breaking a window are set based on the characteristics of the accident. For ground accidents, such as serious land accidents, where escape is relatively easy, damage to the vehicle and unnecessary property loss can be minimized while ensuring personal safety. For drowning accidents, where escape is extremely difficult, the best time to break a window must be chosen by those present, based on the on-site conditions, to maximize the probability of survival.

[0042] Furthermore, the accident detection unit includes a collision detection unit 31 for detecting the intensity of a vehicle collision, a water immersion detection unit 32 for detecting the degree of immersion of a vehicle, and a fire detection unit 33 for detecting whether a vehicle is on fire.

[0043] Furthermore, the collision sensing unit 31 has a collision sensor for detecting deceleration or inertial force, and also has a threshold for determining the degree of collision accident based on deceleration or inertial force. When the signal of the collision sensor exceeds the threshold corresponding to a serious land accident, the vehicle is determined to be in a serious land accident state. When the signal of the collision sensor does not exceed the threshold corresponding to a serious land accident, the vehicle is determined to be in a minor accident state.

[0044] Vehicles are typically equipped with multiple collision sensors that operate on the principle of piezoelectric effect or strain gauge: when a vehicle collides, the vibrating block or piezoelectric crystal inside the sensor deforms due to inertial force, causing a change in resistance or output voltage, thereby generating an electrical signal.

[0045] Collision accidents are classified into minor, moderate, and severe collisions, each corresponding to a different threshold.

[0046] Minor collision: The deceleration is low and the signal strength does not reach the airbag trigger threshold, which may only trigger the seat belt pretensioner or warning light.

[0047] Moderate collision: When the deceleration reaches a certain value and the signal strength is sufficient to determine that protection is needed, the airbags will be deployed and the fuel pump power will be cut off.

[0048] Severe collision: Extremely high deceleration, signal strength exceeding the corresponding threshold, immediately triggering all safety actions such as airbag deployment, seatbelt pretensioning, fuel cut-off, and may automatically call for rescue.

[0049] Furthermore, the collision perception unit 31 also has an external camera that assists the collision sensor in sensing the collision intensity. It analyzes vehicle deformation and motion trajectory through image processing technology to determine the degree of collision. For example, it calculates the intersection-over-union (IoU) ratio of vehicle detection boxes in consecutive frames. If the IoU ratio exceeds a threshold, a collision is determined.

[0050] Furthermore, the water-sensing unit 32 has a water-sensing sensor that detects changes in water pressure, humidity, or water level. The signals detected by the water-sensing sensor are ultimately transmitted to the control module. The control module makes judgments based on preset logic and executes corresponding operations, such as: illuminating warning lights to alert the driver; limiting engine power to prevent damage; triggering safety devices, such as automatic window closing and seatbelt release, to create conditions for escape; and even activating airbags to provide buoyancy and breathing air for the occupants.

[0051] Furthermore, the water-sensing sensor is a pressure sensor. The water-sensing unit 32 includes multiple pressure sensors installed around the vehicle body. The signals from these pressure sensors determine whether the vehicle has submerged, whether the water depth exceeds the vehicle's level, and whether the vehicle body is submerged after a rollover. At least one of these pressure sensors is installed at each of the four corners of the front and rear bumpers, the four corners of the vehicle's roof, and between adjacent doors on the side of the vehicle.

[0052] Furthermore, the fire detection unit 33 has a temperature sensor for detecting whether the vehicle is on fire, and determines whether a fire has occurred by real-time monitoring and anomaly analysis of the temperature of key parts of the vehicle.

[0053] Temperature sensors are typically installed in areas of a vehicle prone to high temperatures, such as the engine compartment, battery pack (for new energy vehicles), exhaust system, tires, and wheel hubs. These locations are high-risk areas for fire, and the sensors can promptly detect temperature changes.

[0054] Temperature sensors continuously collect temperature data and transmit it to the central control unit 1 via the vehicle network. Data collection is performed at a high frequency, such as once per second, to ensure timeliness.

[0055] For critical components, such as power batteries, temperature sensors need to have high accuracy and fast response capabilities, for example, they should be able to immediately trigger an alarm when the temperature exceeds 120°C.

[0056] The central control unit 1 has preset normal temperature ranges, for example, the normal temperature of the engine compartment is below 150°C and the battery pack is below 60°C, and the thresholds are dynamically adjusted based on historical data or standard values.

[0057] When the temperature sensor detects an abnormal temperature rise, such as exceeding the material's ignition point (180°C for rubber, 427°C for gasoline), or an abnormal rate of temperature change (such as a temperature spike of over 200°C within one minute), the main control unit 1 determines that the vehicle is on fire.

[0058] To improve the accuracy of fire detection, the temperature of multiple locations can be monitored simultaneously to avoid false alarms.

[0059] When the temperature sensor reading exceeds the preset temperature threshold in the central control unit 1, the vehicle's instrument panel will display a warning, such as the temperature gauge entering zone H, the malfunction indicator light flashing, and an audible alarm triggered, reminding the driver to stop the vehicle immediately.

[0060] In the event of a serious risk, such as overheating of the power battery, the main control unit 1 can automatically activate the vehicle's fire extinguishing device and spray continuously for more than 10 minutes to prevent reignition.

[0061] Furthermore, the fire detection unit 33 also has an image analysis component that assists the temperature sensor in determining whether a vehicle is on fire. Cameras are installed inside and outside the vehicle. After the cameras capture images, the image analysis component analyzes the video stream obtained by the cameras in real time using AI algorithms. Based on the unique color, flickering frequency, irregular shape of the flame, as well as the diffusion pattern and concentration changes of the smoke, it determines whether a vehicle is on fire.

[0062] In some embodiments of this application, the in-vehicle detection unit includes multiple in-vehicle cameras 51 with different perspectives for monitoring the in-vehicle scene. The in-vehicle detection unit also has an image analysis module 52 electrically connected to all the in-vehicle cameras 51. The image analysis module 52 determines the category and activity of the people in the vehicle based on the monitoring of the multiple in-vehicle cameras 51.

[0063] Age recognition for occupants in vehicles is primarily determined by analyzing human features in images. Mobility recognition for occupants is mainly achieved by tracking key points on the head and limbs, as well as the direction of their gaze, to comprehensively assess their mobility.

[0064] The working principle of image analysis module 52 is as follows: In-vehicle cameras capture images of occupants, requiring sufficient lighting to improve recognition accuracy. In low-light conditions, infrared illumination can be used to enhance image quality. The original image undergoes grayscale conversion, histogram equalization, and size normalization to eliminate noise interference. For example, the OpenCV library can be used for fast face detection and facial region localization.

[0065] Analysis of the categories of people inside the vehicle The model uses a neural network to detect the position of facial features, eye opening and closing, and head orientation. Adult facial features are generally more three-dimensional, while children's are relatively rounder; these differences provide a basis for age classification. Further analysis of height-to-head ratio is conducted. An adult's head accounts for approximately 1 / 8 to 1 / 7 of their height, while children's heads are proportionally larger. Using vehicle seats as a reference, height range can be estimated, aiding in age determination. A convolutional neural network is used to construct an age classification model, with preprocessed facial images as input and adult or child as output. The model learns features through extensive labeled data, such as the difference between adult facial wrinkles and infantile chubby cheeks.

[0066] Analysis of the activities of people inside the vehicle This study uses a neural network model to track key points on the head and limbs, analyzing changes in joint angles and the smoothness of movement. Individuals with limited mobility may exhibit limb stiffness, reduced range of motion, or balance problems. By combining eye tracking and gesture recognition, the study verifies an individual's ability to interact with their environment. For example, it detects whether an individual can independently adjust their seat, operate in-vehicle equipment, or respond to external commands. Facial expressions and head orientation are analyzed to identify states such as fatigue or confusion, indirectly inferring mobility. For instance, persistently closed eyes or a drooping head may indicate decreased mobility. A convolutional neural network is trained, taking a preprocessed image sequence as input and outputting a mobility category: normal or comatose. The model learns features through extensive labeled data, such as the continuity of movement in a normal state and the near-static range of motion in a comatose state.

[0067] Furthermore, all the in-vehicle cameras 51 of the in-vehicle detection unit can completely cover every seat in the vehicle, so as to realize the analysis and monitoring of all people in the vehicle.

[0068] In some embodiments of this application, the window breaking control system further includes a door lock opening and closing unit 7 electrically connected to the main control unit 1. The door lock opening and closing unit 7 is used to control the opening and closing of the vehicle door lock. In the event of a serious land accident, the main control unit 1 controls the door lock opening and closing unit 7 to unlock the vehicle door.

[0069] In the technical solution, for severe land-based accidents, the vehicle doors can be automatically unlocked while the occupants have the mobility to escape quickly, minimizing damage to the vehicle and avoiding unnecessary property loss. For accidents involving falling into water, where escape is extremely difficult, the door unlocking step can be eliminated, increasing window breaking efficiency, buying time for escape, and improving the probability of survival.

[0070] Furthermore, each door is equipped with the door lock opening and closing unit 7. In the event of a serious land accident, the central control unit 1 controls the door lock opening and closing units 7 of all doors to unlock synchronously, so that people in all positions inside the vehicle can evacuate the vehicle at the same time.

[0071] In some embodiments of this application, during a severe land accident, the process by which the central control unit 1 determines whether a window needs to be broken is as follows: based on the detection results of the in-vehicle detection unit, the type and activity status of the people inside the vehicle are determined; if there is no adult activity signal inside the vehicle, it is determined that a window needs to be broken; if there is an adult activity signal inside the vehicle, the opening and closing status of the vehicle door is determined; if the vehicle door is open, it is determined that a window does not need to be broken; if the vehicle door is not open, the triggering status of the detonation switch 6 is determined, and after the detonation switch 6 is triggered, it is determined that a window needs to be broken. When the window falls into the water, the main control unit 1 determines the triggering status of the detonation switch 6. If the detonation switch 6 is triggered, it is determined that the window needs to be broken; if the detonation switch 6 is not triggered, it is determined that the window does not need to be broken.

[0072] In the technical solution, for severe land accidents where escape is relatively easy, a conscious adult inside the vehicle can determine whether to break a window. If there are no conscious individuals inside, or if the only conscious individual is a young child, then the window must be broken to increase the probability of rescue. For drowning accidents, which are extremely difficult to escape from, the best time to break a window must be chosen based on the conditions at the scene to maximize the chances of survival.

[0073] In some embodiments of this application, the window breaking control system further includes a side curtain airbag triggering unit 8 that is electrically connected to the main control unit 1; after the main control unit 1 determines that the window needs to be broken, it determines whether the side curtain airbag needs to be deployed based on the signals from the in-vehicle detection unit and the accident perception unit; when the main control unit 1 determines that the side curtain airbag needs to be deployed, it controls the side curtain airbag triggering unit 8 to deploy the side curtain airbag before controlling the window breaking unit to perform the first explosion.

[0074] In the technical solution, by deploying side curtain airbags to block the space between the occupants and the windows, the possibility of injury to the occupants from flying glass shards during an explosion can be reduced, as can the possibility of occupants being injured by flying glass shards due to limited space for maneuver.

[0075] In some embodiments of this application, when there is an adult activity signal in the vehicle, it is determined that the side curtain airbags do not need to be deployed; when there is no adult activity signal in the vehicle, it is determined that the side curtain airbags need to be deployed.

[0076] In the technical solution, the need to deploy side curtain airbags is determined based on the type and mobility of the occupants. When the occupants include mobile adults, who possess the ability to protect themselves and others, a secondary explosion of the window can be carried out without deploying the side curtain airbags. This preserves the airbags, reduces unnecessary property damage, and the absence of deployed airbags does not interfere with the escape of the occupants, thus improving escape efficiency. When the occupants are immobile adults or young children who lack self-protection capabilities, the side curtain airbags must be deployed. This reduces the likelihood of injury from flying glass shards during the window explosion, increasing their chances of survival.

[0077] Furthermore, each door is equipped with a side curtain airbag and a side curtain airbag triggering unit 8.

[0078] Furthermore, side curtain airbags are a common existing design in automobiles and are one of the core components of a vehicle's passive safety system. They can quickly deploy from the roof lining to cover the window area, forming a flexible air cushion barrier that effectively reduces the possibility of occupants being cut by flying shards of glass from a collision. Side curtain airbags are disposable devices and must be replaced promptly after a collision.

[0079] Side curtain airbag inflation principle: Solid chemical substances (such as sodium azide) inside the gas generator rapidly decompose, releasing a large amount of nitrogen gas. High-pressure gas is delivered to the roof curtain airbag through a dedicated pipeline, completing inflation within 0.1 seconds to form an airbag approximately 30 cm thick. The airbag is made of high-strength polyester fiber material, capable of withstanding pressures exceeding 2000 Pa, ensuring it does not rupture in a collision.

[0080] In some embodiments of this application, the window breaking control system further includes a countdown reminder unit 9 electrically connected to the main control unit 1. After the main control unit 1 determines that the window needs to be broken, before controlling the window breaking unit to perform the first break, the main control unit 1 controls the countdown reminder unit 9 to emit a sound and / or light representing a countdown to remind people inside and outside the vehicle that the window is about to be broken.

[0081] In this technical solution, occupants inside and outside the vehicle can predict the timing of the window explosion based on the sound and / or light emitted by the countdown reminder unit 9, allowing them to prepare for escape or rescue. This design is particularly beneficial in water-related accidents, increasing the survival rate of occupants.

[0082] Furthermore, the time between the start of sound and / or light from the countdown reminder unit 9 and the first explosion is 5 to 20 seconds, to allow for reaction time for people inside and outside the vehicle, escape preparation time for people inside the vehicle, protection preparation time for people inside the vehicle, and rescue preparation time for people outside the vehicle. Based on this, the escape route is opened in a timely manner to evacuate people inside the vehicle from the accident vehicle within the golden time and improve the survival probability of people inside the vehicle.

[0083] In some embodiments of this application, the detonation switch 6 is provided both inside and outside the vehicle.

[0084] In the technical solution, the detonation switch 6 is installed both inside and outside the vehicle to facilitate rescuers outside the vehicle in rescuing people inside the vehicle and improve rescue efficiency.

[0085] Furthermore, the detonation switch 6 is installed on both the inner and outer sides of each door.

[0086] Furthermore, each of the aforementioned detonation switches 6 can mechanically trigger the corresponding window-breaking unit to break the window in the event of a power outage in the window-breaking control system, thereby reducing the impact of a power outage in the window-breaking control system on escape efficiency.

[0087] In some embodiments of this application, the window breaking control system further includes a detonation request indication module 10 electrically connected to the main control unit 1; the detonation request indication module 10 is located inside the vehicle; when there is an adult activity signal inside the vehicle, if the detonation switch 6 outside the vehicle is triggered before the detonation switch 6 inside the vehicle, the main control unit 1 controls the detonation request indication module 10 to emit sound and / or light to instruct the people inside the vehicle to trigger the detonation switch 6 inside the vehicle; after the detonation switch 6 inside the vehicle is triggered, the main control unit 1 determines that the window needs to be broken.

[0088] In this technical solution, a mobile adult inside the vehicle can be aware of external rescue intentions through the explosion request indication module 10. After ensuring the safety of passengers inside the vehicle, the adult can then confirm the window explosion, reducing the likelihood of injury from flying glass shards during a second explosion. This method, where a mobile adult inside the vehicle confirms the window explosion, effectively reduces the possibility of passengers being injured by flying glass shards due to insufficient space and time for preparation.

[0089] Furthermore, each door is equipped with an explosion request indication module 10 on its inner side. The explosion request indication module 10 emits sound and light simultaneously. The location where the explosion request indication module 10 emits sound and light is near the detonation switch 6 inside the door.

[0090] In some embodiments of this application, the window breaking control system further includes an indicator module 11 electrically connected to the central control unit 1; the central control unit 1 determines whether to issue an indicator signal based on the signals from the accident sensing unit and the in-vehicle detection unit; after determining that an indicator signal needs to be issued, the central control unit 1 issues an indicator signal through the indicator module 11 to guide personnel to open the vehicle door and / or trigger the detonation switch 6. The indicator signal is a voice signal and / or a light signal.

[0091] Furthermore, the instruction signal includes a voice signal so that the person can clearly and explicitly perform actions based on the voice signal instruction.

[0092] Furthermore, the indication signals also include light signals located at the door handle and at the detonation switch 6. When the voice signal instructs a person to open the door, the light signal at the door handle illuminates simultaneously, while the light signal at the detonation switch 6 remains off. When the voice signal instructs a person to trigger the detonation switch 6, the light signal at the detonation switch 6 illuminates simultaneously, while the light signal at the door handle remains off. These light signals help trapped occupants quickly locate the door handle and the detonation switch 6, improving escape efficiency.

[0093] In the technical solution, an indicator signal guides personnel to open the vehicle door and / or trigger the detonation switch 6 to improve escape or rescue efficiency.

[0094] Furthermore, the step of the central control unit 1 in determining whether to issue an indication signal is as follows: The central control unit 1 determines the vehicle status based on the signals from the accident perception unit.

[0095] In the event of a minor accident, the indicator module 11 may issue an indicator signal under the control of the central control unit 1 to guide personnel to open the vehicle door, or the indicator module 11 may not issue an indicator signal.

[0096] In the event of a serious land accident, the central control unit 1 determines the type and activity status of the occupants based on signals from the in-vehicle detection unit. If there is no adult activity signal inside the vehicle, no indication signal is issued; alternatively, the central control unit 1 controls the indication module 11 to issue an indication signal to instruct personnel outside the vehicle to trigger the detonation switch 6 outside the vehicle. If there is an adult activity signal inside the vehicle, the central control unit 1 controls the indication module 11 to issue a first indication signal to instruct personnel inside and outside the vehicle to open the doors. Within a set time period after the first indication signal is issued, if any door is opened, the first indication signal is either stopped or played repeatedly. If all doors remain closed within the set time period after the first indication signal is issued, it indicates that door unlocking has failed, or all doors are jammed and cannot be opened. In this case, the central control unit 1 controls the indication module 11 to issue a second indication signal to instruct personnel inside and outside the vehicle to trigger the detonation switch 6 inside and outside the vehicle.

[0097] When the vehicle falls into the water, the control unit 1 controls the instruction module 11 to send an instruction signal to guide the personnel inside the vehicle to trigger the detonation switch 6 inside the vehicle, and to guide the personnel outside the vehicle to trigger the detonation switch 6 outside the vehicle.

[0098] Furthermore, in the event of a serious land accident, the interval between the first and second indication signals should be 3 to 30 seconds to allow for reaction time and door opening time for the occupants. Based on this, the occupants inside and outside the vehicle should be promptly alerted to trigger the detonation switch 6 so that they can be evacuated from the accident vehicle within the golden time.

[0099] In some embodiments of this application, the window breaking control system further includes a door lock monitoring unit 12 for monitoring the opening and closing status of the door locks; in the event of a serious land accident, the central control unit 1 determines whether the door has been successfully unlocked based on the signal from the door lock monitoring unit 12, and controls the first indication signal issued by the indication module 11 after all doors have been successfully unlocked, so as to avoid people inside and outside the vehicle blindly rushing or pulling on the door before the door is unlocked, reduce unnecessary panic and physical exertion, and conserve more physical strength for escape or rescue.

[0100] Each door is equipped with one of the aforementioned door lock monitoring units 12.

[0101] In some embodiments of this application, each window glass is equipped with an independently usable backup power supply 13 capable of storing electrical energy, a controller, a switch, and warning devices. The backup power supply is normally supplied by the vehicle's main power supply. When the vehicle experiences a power outage due to a collision or other reasons, the backup power supply 13 can provide sufficient electrical energy to withstand two explosions.

[0102] In some embodiments of this application, multiple first detonation modules 21 are evenly arranged around the vehicle window, and multiple second detonation modules 22 are evenly arranged around the vehicle window; both the first detonation module 21 and the second detonation module 22 are provided with a detonator and a combustible explosive material electrically connected to the main control unit 1, and the combustible explosive material in the first detonation module 21 is less than the combustible explosive material in the second detonation module 22.

[0103] To achieve a two-stage explosion of a car window, the first explosion can be initiated by a small amount of high-energy flammable and explosive material evenly distributed around the perimeter of the window, using a low-yield detonation. The shockwave generated by this first explosion propagates at extremely high speeds, approximately 5000-6000 m / s, into the glass, creating strong tensile stress and causing microcracks within the glass. Due to the low energy and uniform distribution, these cracks will connect without causing the glass to disintegrate, and the glass will remain largely intact. The second explosion can be initiated by a larger-yield flammable and explosive material placed at the same location or slightly further away. This explosion generates a higher-energy shockwave that rapidly expands and connects the existing microcracks, while simultaneously creating new cracks. These cracks rapidly expand and intersect within the glass, ultimately causing the glass to shatter into small pieces, completely breaking the window.

[0104] Furthermore, to ensure the second blast fully utilizes the cracks created by the first blast while preventing energy dispersion, the interval between the first and second blasts can be set to 3 to 5 seconds. Simultaneously, the flammable and explosive materials used in the first and second blasts should be placed in the same area, with a protective structure installed outside the flammable and explosive materials used in the second blast to prevent them from being ignited by the impact and heat of the first blast, thus ensuring the time interval between the first and second blasts meets the preset duration.

[0105] Furthermore, each door window is equipped with a window-breaking unit, and all the window-breaking units explode simultaneously to allow people in different positions inside the vehicle to evacuate at the same time.

[0106] In some embodiments of this application, the central control unit is signal-connected to the vehicle control system to perform safety protection actions in the event of a serious land accident. These safety protection actions include, but are not limited to, triggering the airbags, issuing an emergency call, and emitting an audible and visual alarm for the entire vehicle.

[0107] In some embodiments of this application, the countdown reminder unit 9, the explosion request indication module 10, and the indication module 11 are interlocked and run sequentially based on the triggering order. Only one of the countdown reminder unit 9, the explosion request indication module 10, and the indication module 11 runs at the same time period, avoiding mutual interference between their signals and causing guidance confusion, reducing unnecessary panic among the people in the vehicle, improving the operational accuracy of the people in the vehicle, and improving the evacuation efficiency of the people in the vehicle.

[0108] In some embodiments of this application, if the in-vehicle detection unit fails and cannot detect the situation inside the vehicle, the central control unit 1 assumes that there is no adult activity signal inside the vehicle and further determines whether it is necessary to break the window.

[0109] In some embodiments of this application, a vehicle is also provided, the body of which is equipped with the window breaking control system described in any of the above embodiments or any combination of embodiments.

[0110] The technical solution provides a vehicle with a warning system for window breakage. By slightly breaking the window, it buys time for people inside and outside the vehicle to move away from the window, reducing the possibility of injury to people inside and outside the vehicle from the flying glass shards from a second breakage.

[0111] The window-breaking control system described in the preferred embodiment of this application includes all the features of the window-breaking control systems described in all the above embodiments, and its workflow is as follows: The central control unit 1 classifies the vehicle status into serious land accidents, water falls, and minor accidents based on signals from the collision sensing unit 31, the water fall sensing unit 32, and the fire sensing unit 33.

[0112] minor accidents Collisions posing minimal threat to personal safety are classified as minor accidents, eliminating the need to break windows to minimize vehicle damage and avoid unnecessary property loss. Under the control of the central control unit 1, the indicator module 11 can emit voice signals to guide personnel to open the vehicle doors, with the light signal at the door handle illuminating simultaneously, while the light signal at the detonation switch 6 remains off, guiding occupants to evacuate and preventing potential secondary injuries. Alternatively, the indicator module 11 may not emit any indicator signals to conserve energy.

[0113] When falling into the water The control unit 1 and the control instruction module 11 send out voice signals to guide personnel inside and outside the vehicle to trigger the detonation switches 6 inside and outside the vehicle. The light signals at the detonation switches 6 inside and outside the vehicle light up simultaneously, while the light signals at the door handles inside and outside the vehicle remain off. This helps personnel inside and outside the vehicle to quickly identify the location of the detonation switches 6 that they can trigger, so that personnel inside and outside the vehicle can choose the best time to break the window based on the on-site conditions, thereby increasing the survival probability of the people inside the vehicle.

[0114] When the vehicle falls into the water, if the detonation switch 6 outside the vehicle is triggered first, the central control unit 1 determines the type and activity of the people inside the vehicle based on the signals from the in-vehicle detection unit. Different determination procedures are adopted based on whether there are signals of adult activity inside the vehicle: When an adult activity signal is detected inside the vehicle, it indicates the presence of individuals capable of self-protection and protecting others. In this case, it is determined that the side curtain airbags do not need to be deployed, thus preserving them and minimizing unnecessary property damage. Furthermore, the absence of deployed side curtain airbags improves escape efficiency. The central control unit 1 controls the explosion request indication module 10 to emit sound and / or light, instructing occupants to trigger the detonation switch 6 inside the vehicle. An adult capable of movement inside the vehicle, through the explosion request indication module 10, learns of external rescue intentions, quickly identifies the location of the detonation switch 6 that they can trigger, and, after preparing for protection, triggers the detonation switch 6 to confirm the window explosion, reducing the possibility of injury from flying glass shards due to insufficient space and preparation time. After the detonation switch 6 is triggered, the side curtain airbags do not need to be deployed. The central control unit 1 controls the countdown reminder unit 9 to emit sound and / or light, alerting occupants inside and outside the vehicle that the window is about to explode, allowing them to prepare for escape or rescue. Finally, the main control unit 1 controls the window breaking unit to perform the first explosion, keeping the window glass intact but with cracks. After the first explosion, a timer is started, and after a preset time, the window breaking unit is controlled to perform the second explosion to break the window glass.

[0115] When there is no sign of adult activity inside the vehicle, it means there are no individuals inside capable of self-protection or protecting others. In this case, it is determined that the side curtain airbags need to be deployed. The central control unit 1 controls all the side curtain airbag triggering units 8 to deploy all side curtain airbags, protecting all occupants and reducing the possibility of injury from flying glass shards during the explosion, thus increasing their survival rate. The central control unit 1 also controls the countdown reminder unit 9 to emit sound and / or light to alert occupants inside and outside the vehicle that the window is about to explode, allowing them to prepare for escape or rescue. Finally, the central control unit 1 controls the window explosion unit to perform the first explosion, leaving the window intact but with a crack. A timer begins after the first explosion, and after a preset time, the window explosion unit is controlled to perform a second explosion to completely shatter the window.

[0116] When the vehicle falls into the water, if the detonation switch 6 inside the vehicle is triggered first, without deploying the side curtain airbags, the main control unit 1 controls the countdown reminder unit 9 to emit sound and / or light to alert occupants inside and outside the vehicle that the window is about to explode, allowing them to prepare for escape or rescue. Finally, the main control unit 1 controls the window explosion unit to perform the first explosion, leaving the window glass intact but with cracks. After the first explosion, a timer begins, and after a preset duration, the window explosion unit is controlled to perform a second explosion to shatter the window glass.

[0117] In the event of a serious land accident (severe collision, fire) The central control unit 1 controls the door lock opening / closing unit 7 to unlock the vehicle door. The central control unit 1 determines the type and activity of occupants based on signals from the in-vehicle detection unit. Different determination procedures are adopted based on whether there are signals of adult activity inside the vehicle: In a severe land accident, the absence of any adult activity signals inside the vehicle indicates the absence of anyone capable of self-protection or protecting others. In this situation, it is determined that the side curtain airbags need to be deployed. The central control unit 1 controls all side curtain airbag triggering units 8 to deploy all side curtain airbags, protecting all occupants and reducing the possibility of injury from flying glass shards during the explosion, thus increasing their survival rate. Finally, the central control unit 1 controls the window breaking unit to perform a first explosion, leaving the window intact but with a crack. A timer begins after the first explosion, and after a preset time, the window breaking unit is controlled to perform a second explosion to completely shatter the window.

[0118] In a serious land accident, the presence of adult activity signals inside the vehicle indicates the presence of individuals capable of self-protection and protecting others. In this case, it is determined that the side curtain airbags do not need to be deployed to preserve them, minimizing unnecessary property damage. Furthermore, keeping the side curtain airbags in place also improves escape efficiency. After all doors are successfully unlocked, the central control unit 1 controls the indicator module 11 to issue the first instruction signal, guiding occupants inside and outside the vehicle to open the doors. Simultaneously, the light signals at the door handles inside and outside the vehicle illuminate, while the light signals at the detonation switches 6 inside and outside the vehicle remain off. Within a set timeframe following the issuance of the first voice signal, if any door is opened, the first voice signal either stops being issued or loops, indicating that breaking a window is unnecessary. If all doors remain closed within the set time after the first voice signal is issued, it means that the door unlocking has failed or all doors are jammed and cannot be opened. At this time, the control unit 1 and the control instruction module 11 issue a second voice signal to guide the personnel inside and outside the vehicle to trigger the detonation switch 6 inside and outside the vehicle. The light signals at the detonation switch 6 inside and outside the vehicle light up simultaneously, while the light signals at the door handles inside and outside the vehicle remain off.

[0119] If the external detonator switch 6 is triggered first, the central control unit 1 controls the explosion request indication module 10 to emit sound and / or light to instruct occupants to trigger the internal detonator switch 6. Mobile adults inside the vehicle, through the explosion request indication module 10, are aware of external rescue intentions, quickly confirm the location of the triggerable detonator switch 6, and, after preparing for occupant protection, trigger the internal detonator switch 6 to confirm the window explosion, reducing the possibility of occupants being injured by flying window shards due to insufficient space and time for preparation. After the internal detonator switch 6 is triggered, without deploying the side curtain airbags, the central control unit 1 controls the countdown reminder unit 9 to emit sound and / or light to alert occupants inside and outside the vehicle that the window is about to explode, allowing them to prepare for escape or rescue. Finally, the central control unit 1 controls the window explosion unit to perform a first explosion, leaving the window glass intact but with cracks, buying time for occupants inside and outside the vehicle to move away from the window and reducing the possibility of injury from flying window shards during a second explosion. The timing begins after the first explosion, and after a preset time, the window breaking unit is controlled to perform a second explosion to break the window glass.

[0120] Through the description of several embodiments of the window-breaking control system and vehicle provided in this application, it can be seen that the embodiments of the window-breaking control system and vehicle provided in this application have at least the following advantages: 1. This application proposes a window-breaking control system and vehicle, which breaks the car window glass in two stages. The first, minor break serves as a warning, giving occupants inside and outside the vehicle time to move away from the window and reducing the possibility of injury from the flying glass shards during the second break. This application at least partially solves the technical problem that shards from a broken car window can easily cause serious injury to occupants inside and outside the vehicle who are unable to react in time.

[0121] 2. By deploying side curtain airbags and placing them between the occupants and the windows, the possibility of injury to occupants from flying glass shards during an explosion can be reduced, as can the possibility of occupants being injured by flying glass shards due to limited space for maneuver.

[0122] 3. For ground accidents, such as fires and collisions, where the difficulty of escaping is relatively small, the vehicle doors can be automatically unlocked to open an escape route for the occupants without triggering the window breaking unit and the side curtain airbags, thus avoiding unnecessary property damage.

[0123] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
