Description

Technical Field

[0001] The present invention relates to the technical field of automobile safety, and in particular to a water-damaged window breaking device, method and automobile. Background Art

[0002] In recent years, with the improvement of people's living standards, people's demand for cars has also increased, but people's awareness of vehicle safety is relatively weak. Due to the complexity of vehicle driving roads, the severe and changeable traffic weather, and the improper operation of drivers, accidents of cars falling into water occur frequently, so most cars are equipped with window breaking devices.

[0003] Existing window breaking devices are mostly spring-type window breakers, window breaking hammers and combined window breaking devices. These window breaking devices are not restricted. For example, spring-type window breakers and combined window breaking devices are easily activated due to misoperation, and window breaking hammers may be taken away by others or used as toys by children, causing unnecessary damage to the car window glass. Summary of the Invention

[0004] The main purpose of the present invention is to provide a water-flooded window-breaking device, which aims to limit the window-breaking device from being triggered at will and causing damage to the vehicle window glass.

[0005] To achieve the above-mentioned purpose, the present invention provides a water-flooded window breaking device, comprising:

[0006] a linkage rod disposed in the window frame of the automobile, wherein a first rotation connection hole portion, a second rotation connection hole portion, and an operating portion are sequentially provided on the linkage rod, wherein the first rotation connection hole portion and the second rotation connection hole portion both enable the linkage rod to rotate relative to the window frame, and the operating portion can be used to pass through the window frame to be exposed to the passenger compartment of the automobile;

[0007] a window breaking rod, mounted on the linkage rod and arranged corresponding to the second rotation connection hole portion, the window breaking rod extending toward the side of the glass window panel of the automobile; and

[0008] A limiting structure includes a limiting drive device, a first latch and a second latch, wherein the first latch and the second latch are movably mounted in the window frame of the vehicle, and the first latch and the second latch are respectively arranged corresponding to the first rotation connection hole portion and the second rotation connection hole portion;

[0009] When the limit drive device drives the first latch to be inserted into the first rotating connection hole, the second latch avoids the second rotating connection hole, so that when the operating part is operated by external force, the linkage rod rotates with the first rotating connection hole as the rotation center, thereby driving the window breaking rod to move and hit the side of the glass window panel;

[0010] The limit drive device drives the first latch to avoid the first rotating connection hole. When the second latch is inserted into the second rotating connection hole, the linkage rod rotates with the second rotating connection hole as the rotation center to drive the window breaking rod to rotate ineffectively.

[0011] Preferably, the limit drive device includes:

[0012] a motor mounted in a window frame of the automobile;

[0013] A rotating rod, drivingly connected to an output end of the motor;

[0014] Two hinged frames are respectively installed at both ends of the rotating rod; and

[0015] The first latch and the second latch are respectively installed on the two hinge frames.

[0016] Preferably, the first latch and the second latch are both provided with a limit block, and the limit block is slidably connected to the window frame of the car to limit the movement direction of the first latch and the second latch.

[0017] In addition, to achieve the above-mentioned purpose, the present invention also proposes a method for breaking windows by flooding, which comprises:

[0018] Obtaining the water level outside the vehicle door;

[0019] After determining that the water level meets the warning condition, the motor is controlled to drive the first latch to be inserted into the first rotating connection hole, and the warning device is controlled to start, so that the user can operate the operating part to break the window.

[0020] Preferably, a water level associated image outside the car window is obtained, wherein the water level associated image includes a water level height line image and a water level warning line image;

[0021] When the water level height line image is above the water level warning line image, it is determined that the water level meets the warning condition.

[0022] Preferably, a plurality of water level-related images outside the car window within a preset time period are acquired, wherein the water level-related images include a water level height line image, a water level warning line image, and a water level safety line image;

[0023] When, among the multiple water level associated images, each water level height line image is partially above the water level safety line image and partially between the water level safety line image and the water level warning line image, it is determined that the water level height meets the warning condition.

[0024] Preferably, a warning light is controlled to light up to guide people in the car to focus on the button position of the water-flooded window breaking device;

[0025] The control alarm sounds to remind the people in the car that they need to quickly save themselves, and at the same time notify people outside the car to rescue the people in the car.

[0026] In addition, to achieve the above-mentioned object, the present invention further provides a vehicle, comprising:

[0027] multiple doors;

[0028] A plurality of camera devices are respectively arranged on the outside of each vehicle door and located at the top of the window frame of the vehicle door.

[0029] Preferably, a glass window panel and a water-flooded window-breaking device located on a side of the glass window panel are provided in the window frame, and the water-flooded window-breaking device is the water-flooded window-breaking device according to any one of claims 1-3.

[0030] Preferably, a warning device is provided on the inner side of the vehicle door for reminding people in the vehicle to activate the water flooding window breaking device.

[0031] In the technical solution provided by the present invention, the position-limiting structure includes a position-limiting drive device, a first latch, and a second latch. Both the first latch and the second latch are movably mounted within the vehicle's window frame. The first latch and the second latch are respectively positioned corresponding to the first and second rotating connection holes. When the position-limiting drive device drives the first latch to be inserted into the first rotating connection hole, the second latch clears the second rotating connection hole. This allows the linkage lever to rotate about the first rotating connection hole when an external force is applied to the operating portion, driving the window breaker rod to move and strike the side of the glass window panel. The position-limiting drive device drives the first latch to clear the first rotating connection hole. When the second latch is inserted into the second rotating connection hole, the linkage lever rotates about the second rotating connection hole, causing the window breaker rod to rotate in an ineffective manner. In non-emergency situations, the ineffective movement trajectory of the window breaker rod is locked, effectively preventing false triggering caused by vehicle vibration or accidental contact. The exposed operating portion, combined with the warning system, significantly shortens response time in emergencies. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The present invention provides a water-flooded window breaking device. Figures 1 to 2 This is an embodiment of the water-flooded window breaking device provided by the present invention.

[0045] Car window-breaking devices commonly use mechanical mechanisms such as spring-loaded window breakers or window-breaking hammers. These devices require active operation from the vehicle occupant and lack a warning mechanism. When a vehicle accidentally falls into water, the doors become difficult to open due to water pressure. If the window-breaking device is inactive or the operator fails to detect the danger in time, the window can be broken too late, leading to serious consequences. For example, some window-breaking hammers require manual aiming at the edge of the glass, making accurate positioning difficult when the vehicle is tilted or in low light.

[0046] Please also refer to Figures 1 to 2The water-flooded window-breaking device includes a linkage rod 4, a window-breaking rod 1 and a limiting structure, and is applied to a car having a window frame and a glass window panel arranged in the window frame, wherein the linkage rod 4 is arranged in the window frame of the car, and a first rotating connection hole portion 2, a second rotating connection hole portion 3 and an operating portion are sequentially provided on the linkage rod 4, and the first rotating connection hole portion 2 and the second rotating connection hole portion 3 can both enable the linkage rod 4 to rotate relative to the window frame, and the operating portion can be used to pass through the window frame to reveal the interior of the car, the window-breaking rod 1 is installed on the linkage rod 4 and is arranged corresponding to the second rotating connection hole portion 3, the window-breaking rod 1 extends toward the side of the glass window panel of the car, and the limiting structure includes a limiting driving device, a first latch 9 and a second latch 6, the first latch 9 and the second latch The pins 6 are movably installed in the window frame of the car, and the first latch 9 and the second latch 6 are respectively arranged corresponding to the first rotating connection hole portion 2 and the second rotating connection hole portion 3. When the limit driving device drives the first latch 9 to be inserted into the first rotating connection hole portion 2, the second latch 6 avoids the second rotating connection hole portion 3, so that when the operating portion is operated by external force, the linkage rod 4 rotates with the first rotating connection hole portion 2 as the rotation center to drive the window breaking rod 1 to move and hit the side of the glass window panel. The limit driving device drives the first latch 9 to avoid the first rotating connection hole portion 2. When the second latch 6 is inserted into the second rotating connection hole portion 3, the linkage rod 4 rotates with the second rotating connection hole portion 3 as the rotation center to drive the window breaking rod 1 to rotate ineffectively.

[0047] This application proposes a linkage rod 4 disposed within a vehicle window frame. The linkage rod 4 is sequentially provided with two rotational connection holes and an operating portion. A window-breaking rod 1 is mounted on the linkage rod 4 at a position corresponding to the second rotational connection hole 3 and extends toward the side of the glass window panel. A position-limiting structure includes a latch set that can be alternately inserted into the two rotational connection holes. When a first latch 9 is inserted into the first rotational connection hole 2, the operating portion drives the linkage rod 4, using the first hole as a fulcrum, to drive the window-breaking rod 1 against the side of the glass. When a second latch 6 is inserted into the second rotational connection hole 3, the linkage rod 4 rotates about the second hole, causing the window-breaking rod 1 to deviate from its effective window-breaking trajectory.

[0048] The linkage rod 4 refers to a rigid rod with two independent rotational fulcrums, which can be specifically formed from stainless steel and provided with bearing bushings of different diameters in the two rotating connection holes. The window breaking rod 1 refers to an impact component with a tungsten carbide alloy tip at the end, which can be designed as a detachable structure to facilitate the replacement of worn parts. The limit drive device refers to an actuator capable of controlling the axial movement of the latch, which can specifically be implemented by using a micro linear motor 7 in conjunction with a position sensor to achieve precise positioning. The first latch 9 and the second latch 6 refer to cylindrical locking parts with diameters matching the rotating connection holes, and can specifically be provided with a polytetrafluoroethylene coating on the surface to reduce the friction system.

[0049] When the water level monitoring system detects a dangerous water level, the limit drive mechanism pushes the first latch 9 into the first rotation hole 2, exposing the operating unit to the passenger compartment. When the user pushes the operating unit, the linkage rod 4 rotates around the axis of the first rotation hole 2, driving the window breaker rod 1 along a predetermined trajectory to strike the stress concentration area on the side of the glass window panel. When the system detects no dangerous conditions, the second latch 6 is inserted into the second rotation hole 3. Operating the linkage rod 4 only allows the window breaker rod 1 to idle within a safe range, preventing accidental window breaking.

[0050] Therefore, the limiting structure includes a limiting driving device, a first latch 9 and a second latch 6. The first latch 9 and the second latch 6 are both movably installed in the window frame of the car. The first latch 9 and the second latch 6 are respectively arranged corresponding to the first rotating connection hole portion 2 and the second rotating connection hole portion 3. When the limiting driving device drives the first latch 9 to be inserted into the first rotating connection hole portion 2, the second latch 6 avoids the second rotating connection hole portion 3, so that when the operating portion is operated by external force, the linkage rod 4 rotates with the first rotating connection hole portion 2 as the rotation center to drive the window breaking rod 1 to movably hit the side of the glass window panel. The limiting driving device drives the first latch 9 to avoid the first rotating connection hole portion 2. When the second latch 6 is inserted into the second rotating connection hole portion 3, the linkage rod 4 rotates with the second rotating connection hole portion 3 as the rotation center to drive the window breaking rod 1 to rotate ineffectively. In non-emergency situations, the invalid motion trajectory of the window breaker rod 1 is locked, effectively avoiding false triggering caused by driving vibration or accidental touch. The exposed design of the operating part and the warning system significantly shorten the response time in emergency situations.

[0051] Traditional limit devices mostly use a single pin with a spring return structure, which has problems such as slow response speed and low linkage accuracy. This application realizes the synchronous reverse movement of the double pins by driving the combined structure of the rotating rod 8 and the articulated frame 11 through the motor 7.

[0052] Specifically, in an embodiment of the present invention, the limit drive device includes a motor 7, a rotating rod 8 and two articulated frames 11, the motor 7 is installed in the window frame of the car, the rotating rod 8 is driven and connected to the output end of the motor 7, the two articulated frames 11 are respectively installed at both ends of the rotating rod 8, and the first pin 9 and the second pin 6 are respectively installed on the two articulated frames 11.

[0053] Motor 7 is the power source that drives the rotating rod 8, specifically a micro DC motor 7, to provide the torque required for the rotation of the rotating rod 8. Rotating rod 8 is the transmission component that connects the output of motor 7 to the articulated frame 11. Specifically, it can be a metal rod or a composite rod, and is used to convert the rotational motion of motor 7 into linear displacement of the articulated frame 11. Articulated frame 11 is the mechanical structure that connects rotating rod 8 to the latch, specifically a U-shaped bracket or L-shaped connecting rod. It converts the rotational motion of rotating rod 8 into linear motion of the latch, while ensuring the synchronous linkage of the two latches.

[0054] When motor 7 receives a control signal, its output drives rotating rod 8 to rotate, which in turn drives the articulated frames 11 at both ends to swing about their axes. The motion trajectory of articulated frames 11 is controlled by the rotation angle of rotating rod 8. For example, when rotating rod 8 rotates clockwise, the first articulated frame 11 pushes the first latch 9 into the first rotation connection hole 2 of linkage rod 4, while the second articulated frame 11 simultaneously drives the second latch 6 out of the second rotation connection hole 3. At this point, linkage rod 4 rotates around the first rotation connection hole 2, effectively impacting the side of the glass window panel with the window-breaking rod 1. Conversely, when rotating rod 8 rotates counterclockwise, the second latch 6 inserts into the second rotation connection hole 3, shifting the rotation fulcrum of linkage rod 4 to the second rotation connection hole 3. The motion trajectory of window-breaking rod 1 deviates from the glass window panel, resulting in ineffective rotation.

[0055] Furthermore, a limit block 10 is provided on each of the first latch 9 and the second latch 6 . The limit block 10 is slidably connected to the window frame of the car to limit the movement direction of the first latch 9 and the second latch 6 .

[0056] The stopper 10 is a raised structure on the latch. Specifically, it can be made of a metal or plastic block welded to the latch body or integrally molded. Its dimensions are adapted to fit within the pre-set sliding groove within the window frame. This stopper 10, by sliding with the window frame, constrains the latch to a single axial direction. Directional restriction involves guiding the latch's movement through a guide rail or sliding groove. Specifically, this can be achieved by providing a linear groove within the window frame, into which the stopper 10 fits and along which it slides. This structure ensures that the latch, under the action of the drive mechanism, can only be inserted into or exited from the rotating connection hole along a straight path.

[0057] When motor 7 rotates lever 8, articulated bracket 11 drives the latch pin in lateral motion. A stopper 10 slides within the window frame's slot, preventing the latch pin from radially deflecting or rotating, allowing it to move linearly along the slot's extension. For example, when first latch pin 9 needs to be inserted into first pivoting hole 2, stopper 10 slides forward within the slot, precisely aligning the latch pin with the hole. When second latch pin 6 needs to clear second pivoting hole 3, stopper 10 slides in the opposite direction, guiding the latch pin out along a fixed path.

[0059] Step S10: Obtain the water level outside the car door.

[0060] It should be noted that obtaining the water level outside the car door refers to real-time monitoring of the water level changes outside the car through sensors or image recognition devices. Specifically, this can be achieved by using a camera installed on the outside of the car door to collect water level image data to determine whether the water level has reached the critical condition for triggering the window breaking operation; the warning condition refers to the preset water level safety threshold, which can be specifically achieved by analyzing the relative position relationship between the water level height line and the warning line through an image processing algorithm. When the water level line exceeds the warning line, it is determined that the conditions are met to ensure that the early warning mechanism is triggered in time.

[0061] Step S11: Obtain a water level associated image outside the car window, wherein the water level associated image includes a water level height line image and a water level warning line image; when the water level height line image is above the water level warning line image, determine that the water level height meets the warning condition.

[0062] It should be noted that the water level associated image refers to an image obtained by an image acquisition device that includes a water level height line, a water level warning line and a water level safety line. Specifically, it can be achieved by using a camera or water level sensor installed on the outside of the vehicle door, and is used to monitor changes in the water level outside the vehicle in real time. The water level safety line image refers to the marking line corresponding to a pre-set safety water level threshold. Specifically, it can be divided by setting identification lines of different colors or electronic virtual markings on the outside of the vehicle door, and is used to define the range where the water level has not reached a dangerous state. The water level warning line image refers to the marking line corresponding to the pre-set critical water level threshold that triggers the window breaking warning. Specifically, it can be distinguished by a color or position different from the safety line, and is used to determine whether to start the window breaking operation. Determining whether the water level meets the warning conditions means analyzing the relative position changes of the water level height lines, safety lines and warning lines in multiple water level associated images. Specifically, it can be achieved by using image processing algorithms or sensor data analysis modules, and is used to dynamically evaluate the rising trend of the water level and avoid misjudgment.

[0063] Specifically, multiple water-level-related images are continuously collected within a preset time period, and the positional relationship between the water level height line, the safety line, and the warning line in each image is compared. If the water level height line is higher than the safety line in some images and between the safety line and the warning line in other images, it indicates that the water level is showing a fluctuating upward trend and is approaching the danger threshold. At this time, the system determines that the warning conditions are met and triggers the subsequent window-breaking device startup process. For example, 10 groups of images are collected within 30 seconds. If 5 groups of them show that the water level is higher than the safety line and the other 5 groups show that the water level is between the safety line and the warning line, it is comprehensively judged that there is a risk of continued water level rise, and it is necessary to promptly remind the people in the car to take action.

[0064] Furthermore, multiple water level-related images outside the car window within a preset time period are obtained, wherein the water level-related images include a water level height line image, a water level warning line image and a water level safety line image; among the multiple water level-related images, when each of the water level height line images is partially above the water level safety line image and partially between the water level safety line image and the water level warning line image, it is determined that the water level height meets the warning condition.

[0065] The preset duration refers to a pre-set time range, such as 15 seconds, which is used to collect dynamic data on water level changes. The water level associated image refers to an image of the water level status outside the vehicle window taken by a camera device. Specifically, it can be achieved by using a vehicle-mounted camera to capture an image containing a water level height line, a warning line, and a safety line in real time. The water level height line image refers to an image mark reflecting the current actual water level position, such as generated by identifying the boundary line between water and air through an image processing algorithm. The water level warning line image refers to a preset water level critical position mark that triggers a window breaking operation, such as one-third of the vehicle window height. The water level safety line image refers to a reference position mark below the water level warning line, such as one-quarter of the vehicle window height, which is used to distinguish between a safe water level and a potentially dangerous water level.

[0066] By continuously collecting water-level correlation images at multiple time points, the system analyzes the distribution of water level lines between the safety and warning lines. For example, if the water level exceeds the safety line but does not reach the warning line in some images, but is between the safety and warning lines in other images, it indicates that the water level is fluctuating and rising. In this case, the system determines that the water level may continue to rise and triggers the warning condition. This method avoids misjudgments caused by short-term water level fluctuations (such as splashing caused by vehicle bumps) and ensures that the warning condition is only activated in the event of a real danger.

[0067] Step S20: After determining that the water level meets the warning condition, the motor 7 is controlled to operate to drive the first latch 9 to be inserted into the first rotating connection hole 2, and the warning device 5 is controlled to start so that the user can operate the operating part to break the window.

[0068] It should be noted that controlling the action of the motor 7 refers to driving the rotating rod 8 to rotate through an electrical signal, thereby driving the articulated frame 11 to adjust the position of the pin. Specifically, a stepper motor 7 or a servo motor 7 can be used to achieve precise displacement control, so that the first pin 9 is accurately inserted into the first rotating connection hole 2 of the linkage rod 4, thereby locking the rotation fulcrum of the linkage rod 4; controlling the start of the warning device 5 refers to activating the sound and light alarm device, which can be specifically implemented by a combination of an LED warning light and a buzzer, guiding the occupants of the vehicle to quickly locate the operating part and perform the window breaking action through visual and auditory dual prompts.

[0069] Specifically, when the car falls into the water, the camera on the outside of the car door continuously collects water level images and identifies the positional relationship between the water level height line and the preset warning line through the image processing module. If the water level exceeds the warning line, the control module sends an instruction to the motor 7 to drive the rotating rod 8 to rotate, so that the first pin 9 is inserted into the first rotating connection hole portion 2 of the linkage rod 4, and the second pin 6 is disengaged from the second rotating connection hole portion 3. At this time, the linkage rod 4 forms an effective rotation path with the first rotating connection hole portion 2 as the fulcrum, and the window breaking rod 1 can hit the side of the glass window panel. At the same time, the warning light and the buzzer are started synchronously to guide the people in the car to operate the operating part of the linkage rod 4 to complete the window breaking.

[0070] Step S21: Control the warning light to light up to guide the people in the car to focus on the button position of the water-flooded window breaking device; control the alarm to sound to remind the people in the car to quickly save themselves, and at the same time notify the people outside the car to rescue the people in the car.

[0071] It should be noted that a warning light refers to a device used to emit visual signals, which can be specifically implemented by an LED light or a high-brightness light source. Its function is to guide people in the car to quickly locate the operating position of the window breaking device through directional light emission; a warning device refers to a device used to emit sound signals, which can be specifically implemented by a buzzer or a loudspeaker. Its function is to synchronously trigger the self-rescue awareness of people in the car through continuous or intermittent sounds, and transmit rescue signals to the outside of the car.

[0072] Specifically, when the vehicle detects that the external water level has reached a preset threshold, the warning light will immediately activate and project a light beam to the operating part of the water-flooded window-breaking device, so that people in the car can quickly identify the operating position even when their vision is obstructed or in an emergency. At the same time, the alarm will emit a high-frequency alarm sound, which covers the space inside the car through the penetration of sound waves, forcibly awakening the emergency response of the trapped people, and penetrating the car window to transmit a distress message to the outside world. The dual effects of light and sound form a synergistic mechanism to ensure that the linkage response of self-rescue and rescue is completed within a limited time.

[0073] The present invention provides a car.

[0074] The car comprises a plurality of doors and a plurality of camera devices, wherein the plurality of camera devices are respectively arranged on the outside of each of the doors and located at the top of the window frame of the door.

[0075] Each door is equipped with an independent camera, mounted flush with the top of the door window frame. If the vehicle accidentally enters water, the camera continuously captures images of the water level outside the door and transmits the image data to the onboard control system. By analyzing the relative position of the water level and the window, the system determines whether the preset warning conditions have been met and activates the flood-proof window-breaking device. For example, when the water level approaches the bottom edge of the window, the camera captures the contact line between the water surface and the window frame, triggering the window-breaking device's preparatory action.

[0076] Furthermore, a glass window panel and a water-flooded window-breaking device located at the side of the glass window panel are provided in the window frame, the water-flooded window-breaking device includes a linkage rod 4, a window-breaking rod 1 and a limiting structure, and is applied to a car having a window frame and a glass window panel provided in the window frame, wherein the linkage rod 4 is provided in the window frame of the car, and a first rotating connection hole portion 2, a second rotating connection hole portion 3 and an operating portion are provided on the linkage rod 4 in sequence, the first rotating connection hole portion 2 and the second rotating connection hole portion 3 both enable the linkage rod 4 to rotate relative to the window frame, and the operating portion can be used to pass through the window frame to reveal to the passenger compartment of the car, the window-breaking rod 1 is installed on the linkage rod 4 and is provided corresponding to the second rotating connection hole portion 3, the window-breaking rod 1 is extended toward the side of the glass window panel of the car, and the limiting structure includes a limiting drive device, a first latch 9 and a second The latch 6, the first latch 9 and the second latch 6 are all movably installed in the window frame of the car, and the first latch 9 and the second latch 6 are respectively arranged corresponding to the first rotating connection hole portion 2 and the second rotating connection hole portion 3. When the limit driving device drives the first latch 9 to be inserted into the first rotating connection hole portion 2, the second latch 6 avoids the second rotating connection hole portion 3, so that when the operating portion is operated by external force, the linkage rod 4 rotates with the first rotating connection hole portion 2 as the rotation center to drive the window breaking rod 1 to move and hit the side of the glass window panel. The limit driving device drives the first latch 9 to avoid the first rotating connection hole portion 2. When the second latch 6 is inserted into the second rotating connection hole portion 3, the linkage rod 4 rotates with the second rotating connection hole portion 3 as the rotation center to drive the window breaking rod 1 to rotate invalidly.

[0077] When the vehicle is flooded, after the camera device captures that the external water level reaches a preset threshold, the limit drive device drives the first pin 9 to be inserted into the first rotating connecting hole 2. At this time, the linkage rod 4 rotates with the first rotating hole as the fulcrum, and the window breaking rod 1 hits the side of the glass window panel under the drive of the linkage rod 4 to break the window. If the operating part is touched by mistake, the limit drive device can switch the second pin 6 to be inserted into the second rotating hole, and the linkage rod 4 rotates with the second hole as the fulcrum. At this time, the movement trajectory of the window breaking rod 1 deviates from the glass window panel to avoid accidental window breaking. The warning device 5 is started synchronously, and the sound and light signals are used to guide the people in the car to correctly operate the window breaking device.

[0078] Furthermore, a warning device 5 is provided on the inner side of the vehicle door for reminding people in the vehicle to activate the water-flooding window-breaking device.

[0079] When the vehicle detects that the external water level has reached a preset threshold, the LED strip within warning device 5 flashes, creating a circular light effect surrounding the operating unit, while a buzzer emits an intermittent high-frequency sound. This dual light and sound alert penetrates fog or dim lighting inside the vehicle, ensuring that passengers in all positions are aware of the alarm. The location of the operating unit is quickly identified by the light, and passengers simply apply force in the direction of the light to trigger the rotation of linkage lever 4 to break the window.

[0080] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
