I. Product Function

1. Emergency Escape Function
   • The primary function of this device is its role as a car safety hammer. It is equipped with a hardened steel tip, which is designed to break car windows in case of an emergency. In situations such as car accidents, floods, or fires, passengers can use the hammer to quickly shatter the window glass, creating an escape route. The force - concentrated design of the tip ensures that even with relatively little strength, users can effectively break through tempered glass, which is a common type of glass used in car windows.
2. Seat Belt Cutter
   • Integrated within the body of the safety hammer is a sharp seat belt cutter. In an emergency where the seat belt becomes jammed or difficult to release, this cutter can be used to quickly cut through the seat belt. This feature is crucial as it allows passengers to free themselves from the restraint of the seat belt when traditional release mechanisms fail, enabling a faster evacuation from the vehicle.
3. Flashlight Function
   • The yellow multi - functional car safety hammer also doubles as a flashlight. It is equipped with a bright LED light source. This flashlight can be used in various low - light situations, such as when changing a tire at night, searching for items in the car in the dark, or signaling for help during an emergency. The LED light is energy - efficient and provides a focused beam of light, illuminating the surrounding area clearly.

II. Product Application Scenarios

1. Car - related Emergencies
   • In the event of a car accident, especially when the doors are jammed and the windows need to be broken to escape, the safety hammer function is immediately put to use. For example, if a vehicle rolls over or is involved in a collision where the doors are deformed, passengers can grab the safety hammer and break the window to get out. The seat belt cutter can also be used if the seat belt is stuck, preventing the occupants from leaving the vehicle.
   • In case of a flood, when water starts to fill the car, time is of the essence. The multi - functional device can be used to break the window and cut the seat belt, allowing passengers to swim out safely. Similarly, during a car fire, where smoke and heat can quickly make the situation life - threatening, the safety hammer and seat belt cutter are essential tools for a quick escape.
2. Daily Car Use
   • The flashlight function of the device is useful during daily car - related activities. When a driver needs to check the engine at night, the flashlight can provide the necessary illumination. If a passenger drops something under the seat and it's dark inside the car, the flashlight can be used to locate the item. Additionally, when changing a flat tire on the side of the road at night, the flashlight helps the driver to see the tools and the tire - changing process clearly.
3. Outdoor and Travel Situations
   • When traveling in remote areas, especially at night, the multi - functional device can be used as a general safety and lighting tool. If the car breaks down in an isolated area, the flashlight can be used to signal for help, either by flashing it in a Morse - code pattern or simply to make the vehicle more visible to passing traffic. The safety hammer can also be used as a self - defense tool in case of any unexpected threats in the outdoors.

III. Product Specifications

1. Physical Dimensions
   • Length: The device typically has a length of approximately 8.26in. This length is designed to provide a comfortable grip for users of different hand sizes, allowing for effective use of both the hammering and cutting functions.
   • Width: It has a width of around 3 in at its widest point. The width is carefully designed to house the various components, such as the seat belt cutter and the flashlight components, while still maintaining a compact and easy - to - handle profile.
   • Weight: The multi - functional car safety hammer with flashlight weighs approximately 180 grams. This weight is balanced, ensuring that it is not too heavy to carry around in the car but heavy enough to generate sufficient force when used as a hammer to break glass.
2. Hammer Component
   • Hammer Tip Material: The tip of the safety hammer is made of high - quality hardened steel. This steel has a high hardness rating, typically around [hardness value] on the Rockwell hardness scale. This ensures that it can withstand the impact required to break car windows without deforming or breaking itself.
   • Hammer Head Design: The head of the hammer is designed with a conical shape to concentrate the force at the tip. The angle of the cone is optimized to maximize the impact energy transfer to the glass surface, making it easier to break through the glass.
3. Seat Belt Cutter Component
   • Blade Material: The seat belt cutter is made of a sharp and durable stainless - steel blade. The blade has a thickness of [blade thickness value] mm, which provides the necessary strength to cut through the seat belt fabric while remaining sharp over time.
   • Cutter Mechanism: The cutter is designed in a way that it can be easily accessed and used. It is usually located on the side of the device, and a simple sliding or flipping motion can expose the blade for use. The cutter is designed to cut through standard automotive seat belts with minimal effort.
4. Flashlight Component
   • LED Type: The flashlight uses a high - brightness LED, such as a CREE LED. This type of LED provides a high lumen output, typically around [lumen value] lumens. The high lumen output ensures that the flashlight can provide sufficient illumination in low - light conditions.
   • Battery Type and Capacity: It is powered by [battery type, e.g., AAA] batteries. The device usually has a battery capacity that allows for continuous operation of the flashlight for approximately [operating time value] hours on a single set of batteries. The battery compartment is designed to be easily accessible for battery replacement.
   • Light Modes: Some models may offer multiple light modes, such as a high - beam mode for maximum illumination, a low - beam mode for longer - lasting use, and a strobe mode, which can be used for signaling in emergency situations.
