[0049] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0050] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0051] A multi-functional emergency rescue tool, such as Figures 1 to 5 As shown, the device includes a plastic housing 1, a circuit board assembly, a battery 3, an eccentric firing pin mechanism 4, and a cutter 5; the battery 3 powers the circuit board assembly. This invention uses a plastic housing 1, which is sturdy, durable, and lightweight, making it easy to carry and use. It effectively protects the internal circuit board assembly and battery 3, without adding excessive burden to the user.

[0052] The eccentric striking pin mechanism 4 is used to break windows. In an emergency, its unique eccentric design can generate a large impact force with a small force, efficiently breaking obstacles such as car windows and thus quickly opening an escape route.

[0053] A buzzer 16 is mounted on the second circuit board 8, and a corresponding second hole is provided on the first narrow side. It can emit a high-decibel alarm sound to attract the attention of surrounding people at the rescue site or in emergency situations, serving as a warning and call for help, effectively improving rescue efficiency. The buzzer 16 is mounted on the second circuit board 8 in a reasonable layout, facilitating wiring and debugging. The corresponding second hole on the first narrow side ensures that the sound of the buzzer 16 can be transmitted smoothly, guaranteeing sound propagation. Furthermore, the size and position of the second hole are rationally designed so as not to significantly affect the overall structural strength of the casing.

[0054] The eccentric firing pin mechanism 4 and the cutter 5 are mounted side-by-side on the rear end face of the plastic housing 1. This layout makes the functional areas of the entire rescue tool clear, allowing the user to quickly and accurately find and use the required tools during operation, thus improving rescue efficiency. Furthermore, the side-by-side mounting method makes the overall structure of the tool compact and reasonable, facilitating carrying and storage.

[0055] like Figure 1 , Figure 2 As shown, the circuit board assembly includes a first circuit board 7 and a second circuit board 8. The first circuit board 7 and the second circuit board 8 are connected to each other in an L-shaped structure, and the first circuit board 7 and the second circuit board 8 are electrically connected. This L-shaped structure design can make full use of the space inside the plastic shell 1, improve the space utilization rate, and make the entire rescue tool smaller and more compact, making it easier to carry.

[0056] At least one first LED 9 is arranged on the first circuit board 7, and the first circuit board 7 faces the front end of the plastic housing 1. A condenser lens 10 is provided on the front end of the first LED 9. The condenser lens 10 can concentrate and focus the light emitted by the first LED 9 to form a high-intensity beam of light, which can illuminate the target area at a greater distance, such as finding trapped people at the rescue site or transmitting distress signals to a distance, thereby improving the lighting effect and practicality of the rescue tool.

[0057] Multiple second LEDs are arranged on the second circuit board 8; these multiple second LEDs can provide a wider illumination range, meeting the needs of close-range lighting and warning. The second circuit board 8 faces a first narrow side of the plastic housing 1, and a transparent plate 11 is provided on this first narrow side in front of the second LEDs. The transparent plate 11 protects the second LEDs from damage by the external environment, such as dust and rain, while ensuring normal light transmission. The material and thickness of the transparent plate 11 are optimized to provide both good light transmittance and sufficient strength and wear resistance, extending the lifespan of the second LEDs.

[0058] The battery 3 is a rechargeable battery 3, and the charging interface 14 is located on the first wide side. The design of the rechargeable battery 3 allows the rescue tool to be reused, reducing the cost of use, while avoiding the inconvenience and environmental pollution caused by frequent battery replacements. Placing the charging interface 14 on the first wide side makes it easy for users to connect the charging cable when charging is needed, and this location will not be accidentally touched or damaged during normal use, improving the convenience and safety of use.

[0059] The first circuit board 7 is equipped with a laser lamp 15, and the front end face has a first hole for the laser lamp 15 to be exposed. The laser lamp 15 has the characteristics of high brightness, high directionality and high monochromaticity. The laser beam emitted by it can form a clear spot of light at a long distance, which can be used to send out distress signals or indicate directions in emergency situations. It has strong visibility and recognition, especially at night or in environments with obstructed vision. The role of the laser lamp 15 is more significant and can effectively improve the success rate of rescue and the chance of survival.

[0060] The second circuit board 8 is equipped with a first button 17 and a second button 18. The first button 17 is used to control the first LED 9 and the laser light 15; the second button 18 is used to control the second LED. By controlling different lighting and signal functions through the first button 17 and the second button 18, the operation is simple and intuitive. Users can quickly adjust the working status of the tool in emergency situations to meet the needs of different scenarios.

[0061] Furthermore, this invention features a design where clicking the first button 17 causes the front surface of the plastic housing 1 to sequentially emit strong light, weak light, flashing light, SOS signal, laser signal, and then turn off. For example, strong light is used for long-distance illumination and attracting attention, weak light is used for short-distance illumination, flashing light and SOS signal are used to send distress signals, and laser signal is used to indicate or call for help in a specific direction. Different light emission modes can be switched sequentially by clicking the button, making operation simple and quick. This allows users to rapidly adjust the tool's working status in emergencies, improving rescue efficiency and success rate.

[0062] This utility model design, when the second button 18 is clicked, sequentially emits red and blue light, strong light, weak light, flashing light, SOS light, violet light, and then turns off from the first narrow side of the plastic housing 1. Red and blue light are commonly used in some countries and regions as warning lights for emergency rescue vehicles, quickly attracting the attention of those nearby and providing excellent warning effects at night or in low visibility conditions. Violet light can be used for specific signal transmission or to provide unique illumination effects in specific environments. For example, in some rescue scenarios, violet light can be used to excite fluorescent markers to help locate trapped personnel or specific objects. Similarly, by clicking the button to sequentially switch between different light emission modes, the user can quickly adjust the tool's working status according to actual needs, improving the tool's practicality and flexibility.

[0063] Pressing and holding either button 17 or button 18 for 3 seconds will activate buzzer 16, causing it to sound. Pressing either button 17 or button 18 again will turn off buzzer 16. This press-and-hold activation method prevents accidental activation of the buzzer 16, ensuring it sounds frequently. The buzzer 16 effectively attracts attention, especially in situations with obstructed vision or insufficient lighting, allowing for rapid communication of a distress signal and improving rescue efficiency. Pressing any button again will turn off buzzer 16, allowing users to conveniently disable it when not needed, avoiding unnecessary interference or wasted power.

[0064] like Figure 1 , Figure 2As shown, the plastic shell 1 has a flat hexahedral structure, including a front face, a rear face, a first wide side face, a second wide side face, a first narrow side face, and a second narrow side face. This flat hexahedral structure design makes the tool compact and lightweight, easy to carry and store, while its polyhedral structure also provides sufficient space and convenience for the arrangement of various functional modules. A plastic cap 6 is fitted onto the rear end of the plastic shell 1 to enclose and hide the eccentric firing pin mechanism 4 and the cutter 5 on the rear end face. This design not only protects the eccentric firing pin mechanism 4 and the cutter 5 from accidental contact or damage in non-emergency situations, but also increases the overall aesthetics and safety of the tool, avoiding potential accidental injury to the user from exposed sharp parts. The plastic cap 6, when combined with the plastic shell 1, forms a flat hexahedral structure. This combination ensures the consistency and integrity of the tool's overall appearance, preventing the cap from disrupting the overall structural design and making the tool more convenient and comfortable to use and carry.

[0065] The plastic cap 6 has a whistle 31 on its surface, and an airflow channel communicating with the whistle 31 is provided inside the plastic cap 6. Specifically, the whistle 31 is located on one side of the plastic cap 6, and the airflow channel includes a resonance chamber 32 and an air outlet 33. The resonance chamber 32 is located inside the plastic cap 6, and the air outlet 33 is located on the rear end face of the plastic cap 6. Airflow passes through the whistle 31 at high speed, creating vibration within the resonance chamber 32. After resonance amplification, the vibration is transmitted through the air outlet 33, producing a sharp sound. Therefore, in this application, the plastic cap 6 has the function of a whistle.

[0066] The plastic housing 1 includes a first housing 27, a second housing 28, and a front cover 24. The first housing 27 and the second housing 28 are joined together to form the main body of the plastic housing 1. The front cover 24 is connected to the front end of the main body, and the plastic cap 6 is fitted onto the rear end of the main body. This modular housing design makes the tool easier and faster to assemble and repair. Each part can be manufactured and processed separately and then assembled, improving production efficiency and product quality. It also facilitates the inspection and replacement of internal components during use.

[0067] The second narrow side is provided with at least one magnetic element 12. This allows it to adhere to the surface of magnetic objects, such as metal objects like vehicles, for easy storage and retrieval. These designs enhance the product's scalability and flexibility, further increasing its practical value. The first wide side is provided with a back clip 13. This design enhances the tool's portability, allowing users to attach it to clothing or a backpack for easy access.

[0068] like Figure 4 , Figure 5 As shown, the eccentric firing pin mechanism 4 includes a slide cylinder 19, a firing pin 20, a first spring 21, and a second spring 22.

[0069] The slide cylinder 19 is connected to the plastic housing 1 via a first spring 21; the first spring 21 is compressed and applies a force to the slide cylinder 19 to move backward. This design allows the slide cylinder 19 to move freely within a certain range, and the slide cylinder 19 will only move when subjected to an external force, thereby preventing accidental triggering.

[0070] The striking pin 20 is installed inside the slide cylinder 19 and connected to the plastic housing 1 via a second spring 22. The slide cylinder 19 has an end hole 25 on its end face for the tip of the striking pin 20 to extend out, and a side hole 26 on its side. The second spring 22, in a compressed state, applies a force to the striking pin 20, causing it to move towards the end face of the slide cylinder 19. The tip of the striking pin 20 is installed at an angle towards the side hole 26 inside the slide cylinder 19. The positioning and release of the striking pin 20 are achieved through the cooperation of the side hole 26 and the end hole 25. The angled installation of the striking pin 20 towards the side hole 26 allows it to more easily disengage from the side hole 26 when subjected to external force, improving the response speed and efficiency of the striking pin 20.

[0071] A limiting ring 23 protrudes from the outer periphery of the firing pin 20, and the end of the firing pin 20 has a stepped frustum-shaped structure. In the non-working state, the limiting ring of the firing pin 20 is locked at the side hole 26 of the slide cylinder 19. It remains in the side hole 26 in the non-working state and will not move arbitrarily, avoiding accidental triggering due to vibration or other factors. In the working state, the slide cylinder 19 moves under force, compressing the first spring and acting on the firing pin 20. The firing pin 20, under the pressure of the slide cylinder, moves a certain distance with the slide cylinder and then disengages from the side hole 26, and is ejected from the end hole 25 of the slide cylinder 19 under the action of the second spring 22. This rapid release mechanism allows the firing pin 20 to break windows quickly with a large impact force, improving rescue efficiency. When using the eccentric firing pin mechanism 4, the slide cylinder 19 moves under force, further compressing the first spring 21. During the movement of the slide cylinder 19, its inner wall compresses the end of the firing pin 20, causing the firing pin 20 to disengage from the side hole 26 of the slide cylinder 19. This linkage mechanism makes the operation process smoother and more efficient. Only one external force is needed to simultaneously start the movement of the slide 19 and the firing pin 20, reducing operation steps and time, and improving availability in emergency situations.

[0072] When using the eccentric firing pin mechanism 4, the slide cylinder 19 will be moved under force to further compress the first spring 21. During the movement of the slide cylinder 19, its inner wall will compress the end of the firing pin 20, causing the firing pin 20 to move a certain distance to further compress the second spring 22. Finally, under the action of the second spring 22, the firing pin 20 will disengage from the side hole 26 of the slide cylinder 19 and be ejected from the end hole 25.

[0073] Specifically, the rear end face of the plastic housing 11 has a deep cavity for accommodating the slide cylinder 19, the firing pin 20, the first spring 21, and the second spring 22. A corrective inclined surface 29 is arranged at a specific position on the inner wall of this deep cavity, and a mounting member 30 is arranged at the bottom end of the deep cavity. One end of the firing pin 20 is connected to the mounting member 30, which prevents the shank end of the firing pin 20 from dislodging from the through hole of the mounting member 30. The two ends of the first spring 21 respectively abut against the inner edge of the slide cylinder 19 and the mounting member 30, and the two ends of the second spring 22 respectively abut against the limiting ring 23 and the mounting member 30, so that the first spring 21 and the second spring 22 can smoothly store energy during operation. The slide cylinder 19 has a side hole 26, which interacts with the limiting ring 23 of the firing pin 20, causing the slide cylinder 19 to move inward along with the firing pin 20 when it moves. Simultaneously, the sliding cylinder 19, sliding inward, compresses the first spring 21 to store energy, and the firing pin 20 compresses the second spring 22 to store energy. Until the corrective tilting surface 29 contacts and interacts with the limiting ring 23, the corrective tilting surface 29 causes the limiting ring 23 to escape the control of the sliding cylinder 19, and finally, under the potential energy of the second spring 22, the firing pin 20 is ejected from the end hole 25 opened on the sliding cylinder 19 to break the window.

[0074] The cutter 5 is located on one side of the slide cylinder 19, and the cutter 5 covers the side hole 26 of the slide cylinder 19. The design of the cutter 5 makes the tool more compact, improves space utilization, and also enhances the tool's practicality. It allows for quick switching to the cutter 5 function in emergency situations to cut obstacles such as safety belts and ropes, providing more possibilities for rescue operations.
