Split type stay wire window breaker and automobile

Abstract

The invention discloses a split type stay wire window breaker and an automobile. The problem that manual window breaking efficiency is low is solved. When receiving an external trigger signal, the controller immediately controls the stay wire motor to start. The stay wire motor firstly pulls out the safety clamp spring through the safety clamp spring stay wire, so that the safety pin is not fixed. And then, the stay wire motor enables the safety pin to rotate through the safety pin stay wire. Rotation of the safety pin triggers the limiting mechanism to be unlocked and enables the limiting mechanism to be separated from the side groove of the window breaking ejector pin. At the moment, the window breaking ejector pin rapidly impacts the automobile window glass through the first through hole in the top of the shell under the action of the window breaking spring (the window breaking spring is in a compressed state), and people in the automobile can escape conveniently or people outside the automobile can be rescued conveniently due to breaking of the automobile tempered glass. And the quick window breaking function under the emergency condition is achieved. The limiting mechanism can effectively prevent the safety pin from being released under the bumpy road condition, so that glass is broken, and the window breaker provides precious escape time for people in a vehicle.

Technical Field

[0001] The present application relates to the field of vehicle accessories, and in particular to a split-type pull-wire window breaker and a vehicle. Background Art

[0002] Cars play an important role in our daily lives. A collision or fire can cause car doors to deform and become unable to open, making escape extremely difficult. Emergency escape devices can quickly break windows, giving those inside the car the golden escape window, allowing them to save themselves or be rescued by those outside.

[0003] With the development of intelligent automobiles, most models use laminated glass. Due to the presence of polyvinyl butyral resin (PVB), it is difficult to break the side window glass. Therefore, the window breaking device is required to have a large impact force to break the laminated glass. It takes a lot of force to use a safety hammer to break the car window glass. At the same time, the driver needs to be in a sober state to use the safety hammer to break the car window glass.

[0004] It can be seen that how to solve the problem of low efficiency of manual window breaking is a technical problem that needs to be solved urgently by people in this field. Summary of the Invention

[0015] The safety pin is provided with a limiting pit that cooperates with the safety ball. When the safety pin is in the locked position, the safety ball is partially embedded in the limiting pit under the elastic force of the safety ball spring; when the safety pin is rotated by the traction of the safety pin cable, the edge of the limiting pit of the safety pin squeezes the safety ball, and after overcoming the elastic force of the safety ball spring, the safety ball is completely compressed back into the first groove.

[0016] As an alternative, in the above-mentioned split-type cable-breaking window breaker, it further includes: a lower cover;

[0017] The lower cover is detachably connected to the bottom of the housing; the lower cover is provided with a second through hole, and the diameter of the second through hole is larger than the diameter of the window-breaking thimble.

Subsequently, the wire-pulling motor rotates the safety pin through the safety pin wire. The rotation of the safety pin will trigger the unlocking of the limit mechanism and cause it to disengage from the side groove of the window-breaking thimble. At this time, the window-breaking thimble, under the action of the window-breaking spring (the window-breaking spring is in a compressed state), quickly impacts the window glass through the first through hole at the top of the housing, facilitating the escape of the vehicle occupants or the rescue of external personnel by breaking the tempered glass of the vehicle.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0045] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0046] The core of this application is to provide a split-type pull-wire window breaker and a car.

[0047] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0048] Figure 1 A schematic diagram of a split-type pull-wire window breaker is provided for an embodiment of the present application, as shown in FIG. Figure 1 As shown, it includes: a wire-pulling motor 11, a safety spring wire 12, a safety pin wire 13, a safety spring 14, a safety pin 15, a limiting mechanism, a window-breaking ejector pin 16, a window-breaking spring 17, a housing 18, and a controller; the limiting mechanism is provided on the top outer wall of the housing 18, and a first through hole is provided on the top of the housing 18; the output end of the wire-pulling motor 11 is connected to the safety spring wire 12 and the safety pin wire 13;

[0049] One end of the safety pin 15 is rotatably fixed to the top outer wall of the housing 18, and the other end is connected to the safety pin cable 13; the safety clip 14 is used to fix the safety pin 15 and is connected to the safety clip cable 12;

[0050] A side groove is provided on the top side of the window breaking ejector pin 16, and a limit block is provided in the middle. The side groove extends through the first through hole; the safety pin 15 is located between the side groove and the limit mechanism; the window breaking spring 17 is sleeved on the window breaking ejector pin 16, with both ends abutting against the limit block and the inner wall of the housing 18;

[0051] The controller triggers the wire pulling motor 11, first pulling out the safety spring 14 through the safety spring pull wire 12, and then rotating the safety pin 15 through the safety pin pull wire 13, triggering the limit mechanism to unlock and disengage the safety pin 15 from the side groove, and the tip of the window breaking pin 16 impacts the car window glass under the action of the window breaking spring 17.

[0052] In this embodiment, the cable pulling motor 11 serves as the power source, and drives the entire window breaking process by retracting and extending the cable. Its output end is connected to the safety snap ring cable 12 and the safety pin cable 13 at the same time. The safety snap ring cable 12 and the safety pin cable 13 are connected to the window breaking actuator 20. The cable pulling motor 11 is one of the common electric motors, and its principle is to utilize the interaction between the magnetic field generated by the current passing through the wire and the magnetic field, thereby generating a torque to drive the motor to move. Different types of motors (such as DC brushed motors, DC brushless motors, etc.) can be selected for the cable pulling motor 11 to adapt to different working environments and performance requirements.

[0053] Figure 2 It is a schematic diagram of a window breaking actuator provided by an embodiment of the present application. Figure 3 It is an exploded schematic diagram of a window breaking actuator provided by an embodiment of the present application. As Figure 2 、 3 shown, a first through hole is provided at the top of the housing 18 of the window breaking actuator 20 for the window breaking thimble 16 to protrude; all core components are accommodated inside.

[0054] The safety snap ring cable 12 and the safety pin cable 13 are respectively used to pull the safety snap ring 14 and the safety pin 15, transmit the pulling force of the motor, and realize the release of the safety snap ring 14 and the rotation of the safety pin 15. They can be directly connected or indirectly connected through a cable support. As Figure 1 shown, the safety snap ring cable 12 is shorter than the safety pin cable 13, so the safety snap ring cable 12 will be pulled first, and then the safety pin cable 13 will be pulled; in addition, as Figure 1 shown, the safety pin cable 13 realizes the pulling and rotation from the side of the safety pin 15 through the cable support 21.

[0055] Figure 4 It is a front cross-sectional view of a window breaking actuator provided by an embodiment of the present application. Figure 5 It is a side cross-sectional view of a window breaking actuator provided by an embodiment of the present application. As Figure 4 、 5 shown, the safety snap ring 14 is used to fix the safety pin 15 to prevent it from being accidentally released in non-emergency situations. One end of the safety pin 15 is rotatably fixed to the top of the housing 18, and the other end is connected to the safety pin cable 13. During the window breaking process, the safety pin 15 triggers the unlocking of the limit mechanism through rotation.

[0056] The limit mechanism is provided on the outer wall of the top of the housing 18, and locks the window breaking thimble 16 under normal circumstances to prevent it from accidentally impacting the window glass. In an emergency, the unlocking is triggered by the rotation of the safety pin 15, allowing the window breaking thimble 16 to pop out.

[0057] A side groove is provided on the side surface of the top of the window-breaking pin 16, and a limit block is provided in the middle. The side groove is used to accommodate the safety pin 15, and the limit block is used to limit the range of motion of the window-breaking pin 16 and compress the window-breaking spring 17. Under the action of the window-breaking spring 17, the window-breaking pin 16 quickly impacts the car window glass to break the window. In this embodiment, the bottom of the window-breaking pin 16 is a pointed end, and the column of the window-breaking pin 16 is not limited to a specific shape in this embodiment, and can be in the form of a cylinder, a prism, etc. The side groove can also be of any shape as long as it can accommodate the safety pin 15, and when the safety pin 15 is not rotated, the window-breaking pin 16 can be stuck by the safety pin 15 through the side groove.

[0058] Window breaker spring 17 fits over window breaker pin 16, with its ends abutting against the stopper and the inner wall of housing 18, respectively. This provides a powerful impact force to window breaker pin 16, ensuring it quickly shatters the window glass. When safety pin 15 rotates and no longer retains window breaker pin 16 through the side groove, the compression of window breaker spring 17 allows it to eject.

[0059] It should be noted that the compression force and stroke of the window breaking spring 17 need to be reasonably designed according to the mass of the window breaking ejector pin 16 and the thickness of the vehicle window glass to ensure sufficient impact force.

[0060] The controller receives an external trigger signal (such as a collision sensor, a water level sensor, etc.) and controls the start of the wire-pulling motor 11 .

[0061] Initial state: Safety retaining spring 14 secures safety pin 15, which is located in the side groove of window breaker pin 16. Window breaker spring 17 is compressed, providing preload force for window breaker pin 16. The limiter locks window breaker pin 16 to prevent it from accidentally popping out.

[0062] Triggering process: The controller receives a trigger signal (such as a collision sensor signal or water level signal). The controller activates the cable-pulling motor 11. Cable-pulling motor 11 first pulls out the safety spring 14 via the safety spring cable 12, releasing the safety pin 15. Then, cable-pulling motor 11 rotates the safety pin 15 via the safety pin cable 13, triggering the release mechanism to unlock.

[0063] Window breaking action: After the limiter mechanism is unlocked, the safety pin 15 disengages from the side groove of the window breaking pin 16. The window breaking spring 17 releases energy, pushing the tip of the window breaking pin 16 into the vehicle window at high speed. The window glass shatters under the impact, providing an escape route for the occupants.

[0064] With the split-type cable-breaking window breaker provided by the embodiments of the present application, when the controller receives an external trigger signal, it will immediately control the cable-pulling motor 11 to start. First, the cable-pulling motor 11 pulls out the safety spring clip 14 through the safety spring clip cable 12, so that the safety pin 15 loses its fixation. Subsequently, the cable-pulling motor 11 rotates the safety pin 15 through the safety pin cable 13. The rotation of the safety pin 15 triggers the unlocking of the limit mechanism and causes it to disengage from the side groove of the window-breaking thimble 16. At this time, under the action of the window-breaking spring 17 (the window-breaking spring 17 is in a compressed state), the window-breaking thimble 16 quickly impacts the vehicle window glass through the first through hole at the top of the housing 18, and the breaking of the automotive tempered glass facilitates the escape of the people inside the vehicle or the rescue of the people outside the vehicle. The rapid window-breaking function in an emergency is realized. The limit mechanism can effectively prevent the safety pin 15 from being released on bumpy road conditions, thus preventing the glass from being broken. This window breaker not only provides valuable escape time for the people inside the vehicle, but also improves the overall safety of the vehicle.

[0065] According to the above embodiments, in a specific embodiment, Figure 6 A schematic diagram of manual triggering provided by the embodiments of the present application is shown in Figure 6 and further includes: a manual cable 22;

[0066] One end of the manual cable 22 is fixed to the manual operation end;

[0067] The other end of the manual cable 22 branches into two branches. The first branch is connected to the safety spring clip 14, and the second branch is connected to the safety pin 15; among them, the first branch is shorter than the second branch.

[0068] On the basis of the original split-type cable-breaking window breaker, this embodiment adds the function of the manual cable 22, aiming to provide a device that can still achieve window-breaking escape through manual operation in case of automatic trigger failure or emergency.

[0069] One end of the manual cable 22 is fixed to the manual operation end, and the other end branches into two branches, which are respectively connected to the safety spring clip 14 and the safety pin 15. When the automatic trigger system fails, the user can pull the manual operation end to sequentially pull the safety spring clip 14 and the safety pin 15 by using the manual cable 22, so as to realize the ejection and window-breaking of the window-breaking thimble 16.

[0070] Before being triggered, the manual cable 22 is in a relaxed state; when triggered, the user needs to pull the manual operation end forcefully to realize the window-breaking action through the transmission of the cable.

[0071] The first branch line is connected to the safety circlip 14, and the second branch line is connected to the safety pin 15, and the first branch line is shorter than the second branch line. When the manual pull wire 22 is pulled, it ensures that the safety circlip 14 is pulled out first, and then the safety pin 15 is pulled and rotated. The short first branch line ensures that the safety pin 15 will not be accidentally triggered under bumpy road conditions or improper operations. By controlling the length difference between the two branch lines, the sequence of the window-breaking action is realized, enhancing the safety and stability of the device.

[0072] The function of the manual pull wire 22 can be replaced by other manual triggering mechanisms, such as manual knobs, buttons, etc., as long as the purpose of pulling the safety circlip 14 and the safety pin 15 in sequence can be achieved. The function of the manual pull wire 22 is particularly important in the case of unstable power supply or failure of the automatic trigger system. In addition, in extreme environments (such as high temperature, low temperature, humidity, etc.), it is necessary to ensure the durability and reliability of the manual pull wire 22 and its connecting components.

[0073] The manual pull wire 22 needs to be made of high-strength and corrosion-resistant materials to ensure reliability under long-term use and harsh environments. At the same time, the design of the manual operation end should be convenient for users to operate quickly and accurately.

[0074] In this embodiment, by introducing the function of the manual pull wire 22, the reliability and flexibility of the split-type pull-wire window breaker are significantly improved. In the case of the failure of the automatic trigger system or in an emergency, users can still achieve rapid window breaking and escape through manual operation. In addition, this solution also retains the advantages of the original automatic trigger system, enabling the device to perform excellently in various scenarios.

[0075] According to the above embodiment, in a specific embodiment, the limiting mechanism includes: a safety ball 23 and a safety ball spring 24; a first groove is provided at the top of the housing 18;

[0076] The safety ball 23 and the safety ball spring 24 are arranged in the first groove from top to bottom. Among them, the bottom end of the safety ball spring 24 is fixedly connected to the bottom of the first groove, and the top end of the safety ball spring 24 elastically supports the safety ball 23;

[0077] The safety pin 15 is provided with a limiting pit that cooperates with the safety ball 23. When the safety pin 15 is in the locked position, the safety ball 23 is partially embedded in the limiting pit under the elastic force of the safety ball spring 24; when the safety pin 15 is pulled and rotated by the safety pin pull wire 13, the edge of the limiting pit of the safety pin 15 presses the safety ball 23, and after overcoming the elastic force of the safety ball spring 24, the safety ball 23 is completely compressed back into the first groove.

[0078] The limit mechanism in this embodiment is composed of components such as a safety ball 23, a safety ball spring 24, a first groove, and a safety pin 15, which realizes the stable locking of the safety pin 15 when the window breaker is not triggered and can be reliably unlocked when triggered. This mechanism plays a key role in ensuring that the window breaker can respond quickly and accurately in an emergency.

[0079] As Figure 4 , 5 shown, the safety ball 23 and the safety ball spring 24 are arranged in the first groove of the housing 18 from top to bottom. The bottom end of the safety ball spring 24 is fixedly connected to the bottom of the first groove, and the top end elastically supports the safety ball 23.

[0080] The safety ball spring 24 provides a continuous upward elastic force for the safety ball 23, so that it partially embeds into the limit pit of the safety pin 15 in the untriggered state, thereby locking the safety pin 15. When not triggered, the safety ball 23 remains locked under the elastic force of the safety ball spring 24; when triggered, the safety pin 15 rotates under the traction of the wire, squeezing the safety ball 23 so that it is completely compressed back into the first groove, unlocking the safety pin 15.

[0081] The safety pin 15 is provided with a limit pit that cooperates with the safety ball 23. The limit pit provides a space for the safety ball 23 to embed, thereby realizing the locking of the safety pin 15. In one embodiment, this limit pit may not be provided.

[0082] When not triggered, the safety ball 23 partially embeds into the limit pit to lock the safety pin 15; when triggered, the safety pin 15 rotates, and the edge of the limit pit squeezes the safety ball 23 to make it exit, realizing unlocking.

[0083] The first groove not only fixes the bottom end of the safety ball spring 24, but also provides limits for the up and down movement of the safety ball 23, ensuring the stability and reliability of the mechanism.

[0084] The cooperation between the safety ball 23, the safety ball spring 24 and the limit pit of the safety pin 15 realizes the reliable locking and unlocking of the safety pin 15. This design ensures the stability of the window breaker in the untriggered state and can respond quickly when triggered. By defining the shapes, sizes of the safety ball 23 and the limit pit, and the elastic force of the safety ball spring 24, the accidental triggering of the safety pin 15 under bumpy road conditions or improper operations can be effectively prevented.

[0085] The limit mechanism in this embodiment realizes the reliable locking and unlocking of the safety pin 15 through a clever design, improving the stability and reliability of the window breaker.

[0086] According to the above embodiment, in a specific embodiment, it further includes: a lower cover 25;

[0087] The lower cover 25 is detachably connected to the bottom of the housing 18; the lower cover 25 is provided with a second through hole, the diameter of the second through hole is larger than the diameter of the window-breaking thimble 16, and the tip of the window-breaking thimble 16 impacts the window glass through the second through hole under the action of the window-breaking spring 17.

[0088] The split-type cable-pulling window breaker in this embodiment includes a lower cover 25. The lower cover 25 is detachably connected to the bottom of the housing 18 and is provided with a second through hole for the window-breaking thimble 16 to pass through. This design not only facilitates the installation and maintenance of the window breaker, but also ensures that the window-breaking thimble 16 can smoothly impact the window glass to achieve the window-breaking function, and can also prevent the window-breaking thimble 16 from being lost.

[0089] The lower cover 25 and the bottom of the housing 18 adopt a detachable connection method, such as screw connection, snap connection, etc. It is convenient for the assembly, disassembly and repair of the window breaker, and improves the maintainability of the product.

[0090] The lower cover 25 is provided with a second through hole, the diameter of which is larger than the diameter of the window-breaking thimble 16, ensuring that the window-breaking thimble 16 can pass through smoothly.

[0091] The connection method between the lower cover 25 and the housing 18, the position and size of the second through hole, etc. need to be specifically designed according to the actual use environment and requirements. The material of the lower cover 25 should have a certain strength and stiffness to withstand the reaction force generated when the window-breaking thimble 16 impacts.

[0092] The structure of the lower cover 25 in this embodiment realizes the easy maintainability of the window breaker and the guarantee of the window-breaking effect through the detachable connection method and the design of the second through hole. This design not only improves the reliability and service life of the product, but also reduces the maintenance cost and time cost, providing a more convenient and efficient use experience for users.

[0093] According to the above embodiment, in a specific embodiment, it further includes: a pin 26;

[0094] One end of the safety pin 15 is rotatably fixed to the outer wall of the top of the housing 18 through the pin 26.

[0095] One end of the safety pin 15 is rotatably fixed to the outer wall of the top of the housing 18 through the pin 26. This connection form allows the safety pin 15 to rotate around the pin 26 when subjected to an external force. In the safe state, the safety pin 15 is fixed by the pin 26 to prevent the accidental release of the window-breaking thimble 16. When window breaking is required, the safety pin 15 is pulled by the cable to rotate around the pin 26 and disengage from the groove of the window-breaking thimble 16, thereby releasing the window-breaking thimble 16.

[0096] Under normal circumstances, the safety pin 15 is fixed to the housing 18 by a pin 26 to ensure that the window-breaking thimble 16 will not be released due to accidental touch or vibration. When a window-breaking signal is received, the wire-pulling motor 11 is activated, and the safety pin 15 is pulled by the wire to rotate around the pin 26, releasing the window-breaking thimble 16, which impacts the vehicle window glass under the action of the window-breaking spring 17.

[0097] According to the above embodiment, in a specific embodiment, the limiting block is a circular retaining plate;

[0098] The diameter of the circular retaining plate is greater than the diameter of the window-breaking spring 17 and the diameter of the second through-hole.

[0099] The split-type wire-pulling window breaker adopts a circular retaining plate as the limiting block. The diameter of the circular retaining plate is designed to be greater than the diameter of the window-breaking spring 17 and the diameter of the second through-hole. This design not only realizes the window-breaking function but also enhances the stability and safety of the window breaker, preventing the window-breaking thimble 16 from being lost after window breaking.

[0100] As Figure 4 、 5 shown, the diameter of the window-breaking spring 17 is smaller than the diameter of the circular retaining plate. Therefore, the window-breaking spring 17 can be compressed between the circular retaining plate and the top of the housing 18. At the same time, the diameter of the circular retaining plate is also greater than the diameter of the second through-hole on the housing 18, ensuring that the window-breaking thimble 16 will not be lost through the second through-hole after popping out.

[0101] The main function of the circular retaining plate is to limit the compression range of the window-breaking spring 17, preventing it from being overcompressed or accidentally released when not triggered. At the same time, it also prevents the window-breaking thimble 16 from popping out of the housing 18 after the window-breaking action.

[0102] In case of emergencies such as vehicle collision or falling into water, even if the entire vehicle loses power, the window breaker still needs to work properly. Preferably, it further includes: a super capacitor;

[0103] The automotive battery is connected to the super capacitor to charge the super capacitor;

[0104] The super capacitor is connected to the wire-pulling motor 11, and the controller controls the super capacitor to discharge to the wire-pulling motor 11.

[0105] Using a super capacitor as a backup power source ensures that the wire-pulling motor 11 can still obtain sufficient power in case of power failure.

[0106] The automotive battery is connected to the super capacitor through a charging circuit to provide a charging power source for the super capacitor. This connection usually uses wires or cables to ensure that the current can be stably transmitted to the super capacitor. The super capacitor is connected to the wire-pulling motor 11 through a discharging circuit. When window breaking is required, the controller controls the super capacitor to discharge to the wire-pulling motor 11 to provide the required power.

[0107] In addition to supercapacitors, other types of energy storage devices can also be considered, such as lithium-ion batteries, nickel-metal hydride batteries, etc. However, these alternative solutions may vary in terms of energy density, charge and discharge speed, or cost.

[0108] Preferably, it further includes: a voltage buck circuit and a voltage boost circuit;

[0109] The automotive battery charges the supercapacitor through the voltage buck circuit;

[0110] The supercapacitor discharges to the wire-pulling motor through the voltage boost circuit.

[0111] Figure 7 A power supply schematic diagram provided for the embodiment of the present application is as Figure 7 shown. During normal operation, the automotive battery supplies power to the motor of the wire-pulling window breaker and simultaneously charges the supercapacitor, and the controller is powered by a voltage of 5V; during abnormal power-off, the single-chip microcomputer is directly powered by the supercapacitor at this time. The single-chip microcomputer communicates with the outside through the LIN communication interface to confirm the current state. If the communication is abnormal, it controls the supercapacitor to boost and discharge to supply power to the motor of the wire-pulling window breaker.

[0112] According to the above embodiment, in a specific embodiment, it further includes a trigger sensor;

[0113] The controller is connected to the trigger sensor; the trigger sensor includes: one or more of a collision sensor, a water level sensor, a smoke sensor, an SOS button, and a camera;

[0114] After the controller receives the collision trigger signal sent by the collision sensor, it triggers the wire-pulling motor 11; after the controller receives the water level overlimit signal sent by the water level sensor, it triggers the wire-pulling motor 11; after the controller receives the smoke alarm signal sent by the smoke sensor, it triggers the wire-pulling motor 11; after the controller receives the alarm signal of the SOS button, it triggers the wire-pulling motor 11; after the controller receives the image information sent by the camera, it judges whether the abnormal condition is met. If so, it triggers the wire-pulling motor 11.

[0115] The split-type wire-pulling window breaker system in this embodiment integrates a variety of trigger sensors and realizes the automatic window-breaking function in case of emergency through the controller. The system mainly includes key components such as a trigger sensor, a controller, a wire-pulling motor 11, and a window-breaking actuator.

[0116] The trigger sensor (such as a collision sensor, a water level sensor, a smoke sensor, an SOS button, and a camera) is connected to the controller through electrical signal lines or wireless signals. This connection allows the sensor to send a signal to the controller when an emergency is detected. The controller is connected to the wire-pulling motor 11 through an electrical signal line to control its start and stop.

[0117] The trigger sensor is responsible for monitoring various emergency situations of the vehicle, such as collisions, water ingress, fires, etc. When the sensor detects an emergency, it sends an electrical signal or a wireless signal to the controller. After receiving the signal, the controller decides whether to initiate the window-breaking action through internal logic processing. Once the controller decides to initiate the window-breaking, it controls the wire-pulling motor 11 to work through an electrical signal, thereby pulling the window-breaking actuator to complete the window-breaking action.

[0118] In this embodiment, the specific installation positions and quantities of the collision sensor, water level sensor, smoke sensor, SOS button, and camera are not limited and can be specifically set according to actual needs.

[0119] In addition to the listed trigger sensors, other types of sensors, such as temperature sensors, gas sensors, etc., can also be added according to actual requirements to monitor different types of emergency situations.

[0120] By integrating multiple trigger sensors and an intelligent controller, the split-type wire-pulling window breaker system in this embodiment can quickly and accurately perform the window-breaking action in an emergency, providing valuable escape time for the people inside the vehicle.

[0121] Finally, the embodiment of the present application also provides a vehicle, including the above-mentioned split-type wire-pulling window breaker, and the split-type wire-pulling window breaker is fixed on the inner sheet metal of the car door through fixed screw holes.

[0122] Figure 8 This is an installation schematic diagram of a split-type wire-pulling window breaker provided by the embodiment of the present application. As Figure 8 shown, the split-type wire-pulling window breaker is connected to the inner sheet metal of the car door through fixed screw holes. This connection method is firm and reliable, which can ensure that the window breaker remains stable during the vehicle's driving process and can also effectively play its role in an emergency.

[0123] The window breaker is fixed on the inner sheet metal of the car door through fixed screw holes, and the window breaker cannot affect the lifting function of the door and window glass. No matter where the automotive glass is located, the window-breaking thimble 16 can break the tempered or laminated glass. The installation point is generally the edge position after the glass is fully raised.

[0124] To ensure the firm connection between the split-type wire-pulling window breaker and the inner sheet metal of the car door, parameters such as the position, quantity, and size of the fixed screw holes need to be defined. These parameters should be reasonably designed according to the actual size and weight of the window breaker and the structural characteristics of the car door.
