A window breaker

Abstract

This utility model discloses a window breaker, comprising: an outer shell, within which are disposed a sensing module, a control module, and an execution module. The sensing module is electrically connected to the control module, and the control module is electrically connected to the execution module. The execution module includes a cylinder, a piston head, and a gas generator. The gas generator is located at one end of the cylinder, and the piston head is slidably disposed within the cylinder. The control module includes a relay connected to the gas generator. When the relay is energized, the gas generator ignites to generate high-pressure gas, which pushes the piston head to move axially along the cylinder to impact the vehicle window. The execution module adopts a "gas generator + cylinder + piston head" structural design. The high-pressure gas generated by the ignition of the gas generator can instantly push the piston head to move axially along the cylinder, forming a powerful impact force. This power method is more labor-saving than traditional manual window breakers, and the impact force is concentrated and stable, effectively shattering the vehicle's reinforced glass and ensuring a high success rate in breaking the window.

Description

Technical Field

[0001] This utility model relates to the field of vehicle safety protection equipment, and in particular to a window breaker. Background Technology

[0002] Currently, most vehicle window breaking devices are traditional mechanical structures, such as window breaker hammers and portable pin-type window breaker, which have obvious structural defects. Simple execution structure: Traditional window breakers rely on manual impact or pressing, and have no high-pressure gas drive structure. They require a lot of manpower to break tempered glass, making them unsuitable for the elderly, children, or injured occupants. Lack of protection and unlocking structure: The manually triggered parts lack an unlocking mechanism, making them prone to accidental triggering and posing a safety hazard. Some products also lack waterproof and accidental trigger prevention structures, resulting in poor reliability in humid or bumpy environments. Power supply structure defects: Most window breakers do not have independent power supply and rely solely on the vehicle's power supply. If the vehicle is involved in a collision or falls into water and causes a power outage, the window breaking function will be completely ineffective.

[0003] To address the above problems, a window breaker is proposed for solution. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides a window breaker.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a window breaker, comprising: an outer shell, wherein a sensing module, a control module and an execution module are disposed within the outer shell, the sensing module is electrically connected to the control module, the control module is electrically connected to the execution module, the sensing module collects vehicle environmental parameters and transmits them to the control module, and the control module controls the execution module to work according to the parameter values; The execution module includes a cylinder body, a piston head, and a gas generator. The gas generator is located at one end of the cylinder body, and the piston head is slidably located within the cylinder body. The control module includes a relay connected to the gas generator. The relay controls the power supply to the gas generator. When the relay is energized, the gas generator ignites to generate high-pressure gas, which pushes the piston head to move axially along the cylinder body to impact the car window.

[0006] In a preferred embodiment of the present invention, the execution module further includes a spring assembly, which includes a return spring. The return spring is sleeved on the end of the piston head away from the window. After the piston head completes the window-breaking action, the return spring can push the piston head back to its initial position.

[0007] In a preferred embodiment of this invention, the free end of the piston head has a conical structure.

[0008] In a preferred embodiment of this utility model, the sensing module includes a water level sensor, a collision sensor, a temperature and humidity sensor, and a gas concentration sensor. The gas concentration sensor is disposed on one side of the water level sensor, and the temperature and humidity sensor is disposed on the other side of the water level sensor.

[0009] In a preferred embodiment of this utility model, a breadboard is provided inside the outer casing, and the water level sensor, collision sensor, temperature and humidity sensor, and gas concentration sensor are all disposed on the breadboard.

[0010] In a preferred embodiment of this utility model, the execution module further includes a manual triggering component, which includes an unlocking knob and a manual switch. The unlocking knob is connected to the manual switch to unlock it. The manual switch is connected to the control module to control the operation of the control module.

[0011] In a preferred embodiment of this utility model, the control module includes a microcontroller, which is an STM32 microcontroller.

[0012] In a preferred embodiment of this utility model, a power module is disposed within the outer casing. The power module includes a charging interface and a battery, and the charging interface is a vehicle power interface.

[0013] In a preferred embodiment of this utility model, a communication module is provided inside the outer shell, and the communication module includes an Internet of Things (IoT) model box, which is disposed on the breadboard.

[0014] In a preferred embodiment of the present invention, the outer shell surface is provided with a fixing member, and there are at least two fixing members, which are respectively disposed on different sides of the outer shell and are of different sizes.

[0015] This utility model solves the defects existing in the background technology, and has the following beneficial effects: This invention establishes a complete automatic control chain of "environmental monitoring - signal processing - action execution" through the electrical connection of the sensing module, control module, and execution module. When a vehicle encounters danger (such as a collision or wading), the environmental parameters collected in real time by the sensing module trigger the control module, automatically activating the execution module without manual operation. This solves the problem of people being unable to manually break windows due to panic or injury in emergency situations, thus buying crucial time for escape.

[0016] In addition, the execution module adopts a structural design of "gas generator + cylinder block + piston striker". The high-pressure gas generated by the ignition of the gas generator can instantly push the piston striker to move axially along the cylinder block, forming a powerful impact force. This power method is more labor-saving than traditional manual window breakers, and the impact force is concentrated and stable, which can effectively shatter the vehicle's tempered glass and ensure a high success rate of window breaking.

[0017] The control module directly controls the power supply to the gas generator via relays. The switching characteristics of the relays enable instantaneous triggering of the gas generator, reducing the delay from "hazard identification" to "window breaking action" and improving emergency response speed.

[0018] All functional modules (sensing, control, and execution) are integrated into the housing, resulting in a compact overall structure that facilitates installation and fixation within the vehicle without taking up too much space. At the same time, the housing can protect the internal modules and adapt to complex environments such as vibration and temperature changes during vehicle operation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

When a component is said to be "connected to" another component, it can be directly connected to the other component or it may be fixed through another intermediate component.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figures 1 to 6 As shown, a window breaker includes: a housing 1, within which a sensing module 2, a control module 3, and an execution module 4 are disposed. The sensing module 2 is electrically connected to the control module 3, and the control module 3 is electrically connected to the execution module 4. The sensing module 2 collects vehicle environmental parameters and transmits them to the control module 3. The control module 3 controls the execution module 4 to operate based on the parameter values. The execution module 4 includes a cylinder 40, a piston head 41, and a gas generator 42. The gas generator 42 is located at one end of the cylinder 40, and the piston head 41 is slidably disposed within the cylinder 40. The control module 3 includes a relay 31, which is connected to the gas generator 42. The relay 31 controls the power supply to the gas generator 42. When the relay 31 is energized, the gas generator 42 ignites to generate high-pressure gas, which pushes the piston head 41 to move axially along the cylinder 40 to impact the window.

[0025] Through the electrical connection of sensor module 2, control module 3, and execution module 4, a complete automatic control link of "environmental monitoring - signal processing - action execution" is constructed. When the vehicle encounters danger (such as collision, water crossing, etc.), the environmental parameters collected in real time by sensor module 2 will trigger control module 3, and execution module 4 will be automatically started without manual operation. This solves the problem of people being unable to manually break windows in emergency situations due to panic or injury, and buys critical time for escape.

[0026] In addition, the execution module 4 adopts a structural design of "gas generator 42 + cylinder 40 + piston impact head 41". The high-pressure gas generated by the ignition of the gas generator 42 can instantly push the piston impact head 41 to move axially along the cylinder 40, forming a powerful impact force. This power method is more labor-saving than traditional manual window breakers, and the impact force is concentrated and stable, which can effectively shatter the vehicle's tempered glass and ensure the success rate of window breaking.

[0027] The control module 3 directly controls the power supply of the gas generator 42 through the relay 31. The switching characteristics of the relay 31 can realize the instantaneous triggering of the gas generator 42, reduce the delay from "hazard identification" to "window breaking action", and improve the emergency response speed.

[0028] All functional modules (sensing, control, and execution) are integrated into the housing 1, resulting in a compact overall structure that facilitates installation and fixation within the vehicle without taking up too much space. At the same time, the housing 1 can protect the internal modules and adapt to complex environments such as vibration and temperature changes during vehicle operation.

[0029] In a preferred embodiment of this utility model, the execution module 4 further includes a spring assembly 43, which includes a return spring. The return spring is sleeved on the end of the piston head 41 away from the window. After the piston head 41 completes the window breaking action, the return spring can push the piston head 41 back to the initial position. The return spring is sleeved on the piston head 41, and after breaking the window, it can automatically push the piston back to the initial position without disassembling and replacing the core components, which greatly reduces equipment wear and meets the long-term emergency reserve needs of vehicles.

[0030] In a preferred embodiment of this utility model, the free end of the piston head 41 is a conical structure. The gas generator 42 pushes the piston to cooperate with the conical piston head 41. The high-pressure gas can push the piston instantly. The conical structure concentrates the impact force at one point, avoiding the dispersion of force. Even when facing a reinforced car window, it can be quickly broken, reducing the time spent breaking the window.

[0031] In a preferred embodiment of this utility model, the sensing module 2 includes a water level sensor 21, a collision sensor, a temperature and humidity sensor 22, and a gas concentration sensor 20. The gas concentration sensor 20 is disposed on one side of the water level sensor 21, and the temperature and humidity sensor 22 is disposed on the other side of the water level sensor 21. A breadboard 5 is disposed inside the outer casing 1, and the water level sensor 21, the collision sensor, the temperature and humidity sensor 22, and the gas concentration sensor 20 are all disposed on the breadboard 5.

[0032] In a preferred embodiment of the present invention, the execution module 4 further includes a manual triggering component, which includes an unlocking knob 6 and a manual switch 7. The unlocking knob 6 is connected to the manual switch 7 to unlock the manual switch 7. The manual switch 7 is connected to the control module 3 to control the operation of the control module 3.

[0033] In a preferred embodiment of this utility model, the control module 3 includes a microcontroller, specifically an STM32 microcontroller 30. The STM32 microcontroller serves as the control core, enabling it to quickly process the parameter data of the sensing module 2, accurately determine the danger threshold, and trigger the relay 31, thereby shortening the delay of "danger identification - window breaking activation" and providing more time for escape.

[0034] In a preferred embodiment of this utility model, a power module 8 is provided inside the outer casing 1. The power module 8 includes a charging interface 80 and a battery 81. The charging interface 80 is a vehicle power interface, which can be charged in real time through the vehicle power supply. The battery 81 serves as a backup power source to prevent the device from failing when the vehicle loses power.

[0035] In a preferred embodiment of this utility model, a communication module 9 is provided inside the outer casing 1. The communication module 9 includes an Internet of Things (IoT) model box 90, which is mounted on a breadboard 5. The breadboard 5 integrates sensors and the IoT model box 90, thus centralizing the scattered electronic components for easier wiring, maintenance, and future upgrades (such as sensor replacement). This reduces the complexity of disassembling the outer casing. Simultaneously, the IoT model box 90 enables data interaction between the window breaker and the outside world: for example, automatically uploading the vehicle location and hazard type to the emergency platform when a hazard is triggered, or remotely providing feedback on the device status (such as battery level and sensor functionality), helping rescue personnel quickly locate the device. It also allows vehicle owners to regularly check the device's reliability, overcoming the limitations of a "single window breaker function" and forming an "emergency-rescue" linkage closed loop.

[0036] In a preferred embodiment of this utility model, a fixing member 10 is provided on the surface of the outer shell 1. There are at least two fixing members 10, which are respectively provided on different sides of the outer shell 1 and are of different sizes. They can be adapted to different installation positions in the vehicle (such as the dashboard and the inside of the door). The installation is firm and no additional customized accessories are required, making it suitable for various vehicle models.

[0037] When using this utility model: Depending on the installation requirements inside the vehicle (such as the side of the dashboard, the inside of the door, etc.), select a suitable fastener 10 on the surface of the outer casing 1, and secure the window breaker firmly with screws or clips, ensuring that the free end of the piston head 41 is aligned with the window glass.

[0038] Connect the device to a mobile phone or management platform via communication module 9, and check whether the sensor module 2 (water level, collision, temperature and humidity, gas concentration sensor 20), control module 3 (STM32 microcontroller), and execution module 4 are responding normally to confirm that the device is in standby mode.

[0039] Automatic mode (automatically triggered in emergencies) When a vehicle encounters danger (such as a collision, water damage, high temperature, or toxic gas leak), the device automatically activates to break the window. The sensor module 2 collects vehicle environmental parameters in real time (excessive water level, severe collision, abnormal temperature / humidity, excessive concentration of harmful gases, etc.) and transmits the data to the control module 3.

[0040] The STM32 microcontroller quickly analyzes parameters and, if they exceed a preset danger threshold, immediately controls relay 31 to be energized.

[0041] Relay 31 triggers gas generator 42 to ignite, generating high-pressure gas that pushes piston head 41 to move rapidly along the cylinder body 40 axially. The conical free end concentrates the impact force to shatter the car window. After the window is broken, the return spring automatically pushes piston head 41 back to its initial position without manual intervention.

[0042] Manual mode (forced to activate when automatic mode fails) If automatic mode is not activated (e.g., due to sensor malfunction), manual window breaking is required: Rotate the unlocking knob 6 on the outer casing 1 to release the locked state of the manual switch 7 (to prevent accidental activation).

[0043] Pressing the manual switch 7 sends a signal to the control module 3, which energizes the relay 31. The subsequent window-breaking process is the same as in the automatic mode (gas generator 42 works → piston head 41 impacts → return spring returns to its original position).

[0044] This utility model window breaker, through its dual "automatic + manual" triggering, efficient window breaking design, flexible adaptability, and intelligent monitoring function, buys users escape time in emergency scenarios while reducing maintenance costs in daily use, thus balancing safety and practicality.

[0045] Through the above operations, the window breaker can respond quickly in the event of a sudden danger to the vehicle, taking into account both automatic emergency response and manual control, adapting to various emergency escape scenarios, and facilitating long-term maintenance to ensure reliability.

[0046] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
