Description

Technical Field

[0001] The patent involves the fields of automobile spontaneous combustion warning, falling into water warning, warning and rescue of children left in the car. Background Art

[0002] Under scorching sun, when flammable materials inside a car, or a fire in the fuel tank or battery, catch fire, and a car spontaneously combusts while the owner is away, uncontrolled combustion can result in the entire vehicle being written off. In the first quarter of 2023, the number of spontaneous vehicle fires nationwide reached 18,000, with a total for the entire year reaching approximately 72,000. In 2020, there were 209,000 vehicle fires in the United States. Prompt reporting of spontaneous fires is crucial for rescuing the vehicle and its occupants. When a car owner or child is trapped, being able to open the doors and windows and escape successfully is a matter of life and death. Children are the future of our nation, and every loss of a child devastates a family and represents a significant loss to the nation's future. However, reports of children suffocating in cars are frequent worldwide. For example, cn.bing.com has 93,200 posts about "Child suffocated after owner left the vehicle," demonstrating that child suffocation is a common tragedy. For example, an article on Phoenix.com on March 17, 2025, titled "Struggling for Nearly 30 Minutes!" A six-year-old girl in the United States suffocated to death on a school bus; her caregiver, oblivious to her phone, was sentenced to three years in prison. This patented vehicle spontaneous combustion alarm and rescue module provides emergency warnings and assistance in various scenarios. It is crucial for protecting children's lives and has significant application prospects.

[0003] When a car sinks into water during heavy rain or flooding, the water intrusion alarm and rescue module sounds an audible alarm and uses an infrared detector to determine if anyone is inside. If not, the alarm system remotely connects to the owner's mobile phone to notify them of the car's submersion and its location. If infrared detection indicates a person is trapped inside the submerged vehicle, an audible and blue light alarm sounds. Based on the water depth, the module determines whether a window can be opened. If not, it automatically breaks the sunroof. For vehicles without a sunroof, the rescue module's laser cutting function allows escape by slicing through the roof. An alert text message is also automatically sent, providing the car's location. If the car loses power after flooding at night, the solar-powered rechargeable battery provides power to the water intrusion alarm and rescue module, activating the emergency lighting. The rechargeable battery is normally charged by solar energy. The water intrusion alarm and rescue module's oxygen content detection and self-oxygenation function electrolyzes water to release oxygen to assist trapped people.

[0004] Every summer, there are frequent tragedies of infants and young children suffocating after being left in cars. When the car is locked, the child alarm module's sound sensor detects a crying child or a movement inside the car. It automatically sends a phone call, text message, and WeChat message to the remote vehicle owner's phone, dials 110, sends an alert text message, and provides the car's location. It also opens or breaks a window to prevent oxygen depletion in the car, potentially leading to hypoxia in the child. When the car is locked and the power is cut off, the solar-powered battery, powered by the child alarm and rescue module, activates the emergency lighting. The battery is normally charged by solar energy. If the oxygen level is low, the self-oxygen function activates by electrolyzing water to release oxygen to help trapped children.

[0005] When harmful molecules such as NO, CO, and CO2 from automobile exhaust are drawn into the room through the air conditioner, and when the indoor content exceeds the standard, the gas sensor will sound an alarm. When it detects that the car owner is trapped in the car, it will sound an alarm and a green light alarm to remind the owner to open the window. If the window cannot be opened, it will automatically break the window glass. At the same time, it will automatically dial the police and provide the car's location. Summary of the Invention

[0006] If flammable materials, the fuel tank, or the battery catch fire inside a vehicle, and the vehicle spontaneously combusts, the smoke sensor in the vehicle fire alarm and rescue module detects smoke, sounds an audible alarm, and outputs a high level. This activates the infrared detector and determines if anyone is inside the vehicle. If no one is inside, the output is level 1, and the alarm system automatically sends a phone call, text message, and WeChat message to the remote vehicle owner's mobile phone, alerting them to the fire. The fire extinguisher is automatically activated to put out the fire, and depending on whether the fire is controllable and extinguishable, the system dials the fire emergency number 119 and provides the vehicle's location. If the infrared detector detects that the vehicle owner is trapped inside the burning vehicle, it outputs level 2, triggering the audible alarm module to sound an audible alarm and a light alarm. The vehicle spontaneously combusts and rescue module issues a voice reminder to open the window. The window opening should be limited to 5 cm to ensure air circulation and prevent children from falling. If the window cannot be opened, the vehicle spontaneously combusts and rescue module automatically breaks the window glass with a pressure hammer, automatically dials the fire emergency number 119, and provides the vehicle's location. If the smoke sensor encounters strong smoke, it issues a voice reminder to wear a mask.

[0007] This patent uses a smoke sensor to detect fires. The smoke concentration is used to determine whether a fire is controllable and extinguishable. If the fire is controllable, the smoke concentration will not increase. If the fire is extinguished, the smoke will dissipate. The automatic window-breaking device has a strong magnet on its back that attaches to the metal window frame. Its power comes from compressed air. The front end of the window-breaking component is made of high-strength alloy steel with a sharp tip. When the switch is triggered, the compressed air rapidly pushes the sharp tip of the alloy steel, shattering the glass. The window to be broken is located on the front passenger seat, away from children in the back seat. To prevent children from being injured by broken window fragments, safety film can be applied to ordinary glass. This film will hold the glass fragments together when it shatters, preventing them from flying and causing harm.

[0008] When a car enters water, the water detector emits an audible alarm and outputs a high level, activating the infrared detector to determine if anyone is inside. If no one is inside, the output is level 1, and the alarm system remotely connects to the owner's mobile phone to alert them to the car's entry. If the car detects that the owner is trapped inside the flooded vehicle, the output is level 2, emitting an audible alarm and a blue light alarm. This prompts the owner to open a window. If the water level is too high and the window cannot be opened, the system automatically breaks the sunroof. If the car lacks a sunroof or is difficult to open, a laser is used to cut the roof to create an escape route. If the window fails to open, the system monitors the oxygen level. When the level falls below the warning level, the system releases self-produced oxygen to assist trapped passengers. An alarm text message is also automatically sent, providing the vehicle's location. If a car enters water at night and loses power, the rescue module's solar-powered rechargeable battery, which is normally charged by solar energy, activates the emergency lighting. In an emergency, the rechargeable battery provides power for the water alarm and rescue module.

[0009] When the car is locked, the child-left-behind alarm module's sound sensor detects a crying child inside, or its motion sensor detects movement. The alarm module initiates an automatic phone call, text message, and WeChat message to the remote vehicle owner's phone. The module automatically dials 110, sends an alert text message, and provides the car's location. The alarm module automatically opens a window or uses a pressure hammer to break the window in an emergency to prevent hypoxia in the child. If the window fails to open, the module monitors the oxygen level. If it falls below the warning level, the self-controlled oxygen function releases oxygen to assist the trapped child. The module also monitors temperature, respiration, heart rate, and other parameters. If the car loses power after being locked, the rescue module's solar-powered rechargeable battery provides power for the child-left-behind alarm and rescue module.

[0010] When the content of harmful molecules such as NO, CO, and CO2 in the car's interior exceeds the standard, the gas sensor of the car's indoor harmful gas excessive alarm module will sound an alarm. When it detects that someone is trapped in the car, the alarm module will issue an audible alarm and a green light alarm reminder, and on the one hand, it will remind you to open the window. If the window cannot be opened, it will automatically impact the pressure hammer to break the window. The excessive alarm module will automatically dial the alarm number and provide the car's location.

The water electrolysis device is usually fixed in the trunk, and the oxygen tube passes through the hole between the rear seat and the trunk and is usually fixed to the child seat or the child's usual sitting position. The hydrogen released by water is harmful and flammable. Activated carbon has a rich pore structure and a large specific surface area, and can physically adsorb hydrogen. Activated carbon is low-cost and non-toxic, or magnesium-nickel alloy (Mg2Ni) can adsorb hydrogen.

[0012] Claims 2 and 4 involve a method for automatically breaking window glass if the window cannot be opened, and a specific explanation includes, but is not limited to: breaking the window by an electrically controlled pressure hammer pre-fixed on the front passenger window; specifically, the electrically controlled pressure hammer is normally in an energy storage state, and when the intelligent device senses that the window cannot be opened, the electrically controlled pressure hammer instantly stores energy and breaks the window.
