Description

Technical Field

[0001] This utility model relates to the field of LED lighting, specifically to a pin-type LED flashlight for breaking windows as an alarm. Background Technology

[0002] Currently, most mainstream LED flashlights on the market focus on a single lighting function, with design primarily emphasizing optimized lighting performance and portability. Features include high-brightness LEDs, multiple brightness levels (strong / weak / strobe), long battery life (lithium battery / Type-C charging), lightweight design, compact size, and non-slip handles. However, these LED flashlights lack functionality in emergency safety scenarios such as fires, car accidents, and drownings, most notably the absence of a window-breaking function. According to data from the Ministry of Emergency Management in 2024, the fatality rate in domestic traffic accidents due to the inability to break windows in time reached 32%, while less than 15% of car owners carry a dedicated window breaker. Furthermore, these LED flashlights have significant shortcomings in expanding safety protection functions, with the lack of an audible alarm being particularly prominent. For example, during outdoor adventures, one might encounter severe weather, wild animal attacks, or accidental injuries, leaving them isolated and helpless, urgently needing to send out a distress signal to receive rescue. In these emergency situations, existing LED flashlights can only provide illumination and cannot attract the attention of those around them or deter threats by emitting high-decibel sounds, making it difficult to meet users' needs for self-protection and emergency assistance.

[0003] Therefore, it is both necessary and urgent to develop an LED flashlight with window-breaking and sound alarm functions. Utility Model Content

[0004] The purpose of this utility model is to overcome the deficiency that there are currently no products on the market that simultaneously have LED lighting and window breaking functions, and to provide a pin-type LED flashlight with window breaking alarm.

[0005] This utility model is achieved through the following technical solution: a pin-type window-breaking alarm LED flashlight, including a cylinder, an LED lighting component disposed at one end of the cylinder, a window-breaking hole disposed at the other end of the cylinder, an installation cavity disposed inside the cylinder and communicating with the window-breaking hole, and a connecting hole disposed on the inner wall of the installation cavity; a pin and a window-breaking component are disposed inside the installation cavity, and a sound alarm module is disposed on the cylinder; the tip of the pin passes through the window-breaking hole and extends to the outside of the cylinder, and the tail end of the pin is in contact with the window-breaking component.

[0006] Depending on actual needs, the sound alarm module can be any one or more combinations of a buzzer, an alarm horn, or a voice alarm.

[0007] The connecting hole divides the mounting cavity into a front cavity and a rear cavity. The window-breaking assembly consists of a movable rod and a return spring located inside the front cavity, and an impact hammer and a main spring located inside the rear cavity. One end of the return spring is fitted onto the end of the movable rod, and the other end is located at the bottom of the front cavity. The tail end of the ejector pin is in contact with the end of the movable rod. One end of the main spring is in contact with the bottom of the rear cavity, and the other end is in contact with the impact hammer. The tail end of the movable rod is in contact with the end face of the impact hammer.

[0008] The impact hammer has an impact hole inside, and the opening of the impact hole is located at the center of the end face of the impact hammer; a contact surface is formed between the outer edge of the opening of the impact hole and the edge of the end face of the impact hammer.

[0009] To ensure the normal operation of this utility model, the tail end of the movable rod is biased towards the side wall of the front cavity under the action of the return spring.

[0010] Furthermore, the movable rod is composed of a thick rod and a thin rod, with the end of the thick rod being the end of the movable rod and the tail end of the thin rod being the tail end of the movable rod; the diameter of the thin rod is smaller than the diameter of the impact hole, and when the thick rod is located inside the connecting hole, the central axis of the movable rod and the central axis of the impact hole are on the same straight line.

[0011] The LED lighting assembly consists of a mirror cover located at the end of the cylinder, a PCB board located inside the cylinder, LED beads located inside the cylinder and connected to the PCB board, a convex lens located inside the mirror cover, and a button and a USB interface located on the cylinder; the button and the USB interface are both connected to the PCB board.

[0012] The lens cap can slide along the end of the barrel to achieve zoom functionality.

[0013] To facilitate observation and understanding of the power consumption, this invention also includes a display connected to a PCB board on the cylinder body.

[0014] To facilitate cutting seat belts, this utility model has a seat belt cutting opening on the cylinder, and a blade for cutting seat belts is provided inside the seat belt cutting opening.

[0015] To prevent the pin from piercing the object when the window-breaking function is not used, a telescopic inner cylinder located inside the window-breaking hole and an auxiliary spring set between the cylinder and the telescopic inner cylinder are provided on the cylinder body; the end face of the telescopic inner cylinder is provided with a pin hole for the pin to pass through, and the telescopic inner cylinder can slide along the inner wall of the window-breaking hole. Under the action of the auxiliary spring, the telescopic inner cylinder extends to the outside of the window-breaking hole and wraps the pin inside it.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] (1) This utility model innovatively integrates LED lighting function, sound alarm function and window breaking function into one flashlight, so that the product has lighting, window breaking and sound alarm functions. Compared with traditional single-function flashlights, it can meet the user's alarm needs in response to sudden dangerous situations in outdoor adventure, emergency rescue and other scenarios, and greatly improve the practicality and applicability of the product.

[0018] (2) In traffic accidents or when windows need to be broken, this utility model can quickly break windows and avoid delaying escape time by switching between multiple tools. Compared with the time required for traditional cutting of seat belts and breaking of windows, this utility model takes less time and only takes 3 to 5 seconds to complete cutting of seat belts and breaking of windows, which is more efficient.

[0019] (3) This utility model does not require a strong impact on the glass during use; only a small pushing force is needed to break the window. At the same time, the window-breaking impact force of this utility model is stable, and it can automatically reset and be reused.

[0020] (4) This utility model is easy to operate and responds quickly. Users can quickly switch between lighting mode, alarm mode and off mode by pressing the button. The sound alarm module can emit an alarm sound of 60 to 120 decibels, which can attract the attention of others in time, effectively improve the alarm efficiency, and save users valuable emergency response time.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0028] Example

[0029] like Figure 1 , 2 As shown, the pin-type window-breaking alarm LED flashlight described in this embodiment mainly consists of a cylinder 1, an LED lighting component set at one end of the cylinder 1, a window-breaking hole 2 set at the other end of the cylinder 1, an installation cavity 3 set inside the cylinder 1 and connected to the window-breaking hole 2, a pin 5 and a window-breaking component 6 set inside the installation cavity 3, and a sound alarm module 17 set on the side wall of the cylinder 1.

[0030] The cylinder body 1, serving as the carrier of the entire device, can be made of either high-strength, waterproof ABS engineering plastic or metal. Waterproof sealing rings are installed at all component connections to effectively prevent moisture and dust from entering the interior, ensuring the flashlight functions normally in harsh environments such as dampness and wading. Its shape is designed to conform to ergonomic principles, providing a comfortable grip for extended use. For ease of description, one end and the other end of the cylinder body 1 in this invention are referred to as the left and right ends, respectively, and these ends can be interchanged depending on the orientation of the cylinder body 1.

[0031] A connecting hole 4 is provided on the inner wall of the mounting cavity 3, which divides the mounting cavity 3 into two parts: a front cavity 71 and a rear cavity 72, and the front cavity 71 and the rear cavity 72 are connected through the connecting hole 4. The connecting hole 4 is formed by protruding inward from the inner wall of the mounting cavity 3, and inclined surfaces 7 are formed between its left and right sides and the inner wall of the mounting cavity 3. The internal thickness of the connecting hole 4 is 0.5 to 3 cm.

[0032] The ejector pin 5 is disposed inside the front cavity 71 and is made of metal. The ejector pin 5 has a pointed tip and a tail end. The pointed tip passes through the window breaker hole 2 and extends to the outside of the cylinder 1, while the tail end of the ejector pin 5 is in contact with the window breaker assembly 6. When breaking the window, the pointed tip is used to pierce the outer glass, while the tail end is used to restrict the movement of the ejector pin 5, preventing it from detaching from the cylinder 1 after passing through the window breaker hole 2.

[0033] The window-breaking assembly consists of a movable rod 61 and a return spring 63 disposed inside the front cavity 71, and an impact hammer 62 and a main spring 64 disposed inside the rear cavity 72. The movable rod 61 is composed of a thick rod 611 and a thin rod 612. The end of the thick rod 611 is the end of the entire movable rod 61, and the tail end of the thin rod 612 is the tail end of the entire movable rod 61. The diameter of the end of the thick rod 611 is larger than its own diameter. This facilitates the fixation of the return spring 63 at the end of the thick rod 611 and increases the contact area between the ejector pin 5 and the movable rod 61, preventing poor contact between the ejector pin 5 and the movable rod 61.

[0034] The diameter of the thin rod 612 must be smaller than the diameter of the connecting hole 4 so that the thin rod 612 can slide freely inside the connecting hole 4. The diameter of the thick rod 611 must match the diameter of the connecting hole 4 to ensure that when the thick rod 611 moves inside, the central axis of the connecting hole 4 and the central axis of the thick rod 611 are on the same straight line.

[0035] The impact hammer 62 is preferably made of metal material into a cylinder. An impact hole 621 is provided on the impact hammer 62. The opening of the impact hole 621 is on the same plane as the end face of the impact hammer 62, and the central axis of the impact hole 621 is on the same straight line as the central axis of the impact hammer 62.

[0036] The plane between the outer edge of the opening of the impact hole 621 and the edge of the end face of the impact hammer 62 is the contact surface 622, which is used to connect with the tail end of the movable rod 61. The diameter of the thin rod 612 is smaller than the inner diameter of the impact hole 621 to ensure that the tail end of the thin rod 612 can slide into the interior of the impact hole 621.

[0037] During connection, one end of the return spring 63 is fitted onto the end of the movable rod 61, while the other end is located at the bottom of the front cavity 71. At this time, the tail end of the ejector pin 5 is in contact with the end of the movable rod 61. One end of the main spring 64 is in contact with the bottom of the rear cavity 72, while the other end is in contact with the bottom surface of the impact hammer 62.

[0038] When the return spring 63 is fixedly connected to the end of the thick rod 611, the contact end of the return spring 63 needs to be tilted to ensure that there is an angle between the central axis of the entire movable rod 61 and the central axis of the mounting cavity 3, so that the tail end of the movable rod 61 (i.e. the tail end of the thin rod 612) is biased toward the side wall of the front cavity 71 and maintains this state.

[0039] The contact connection described in this embodiment refers to two components that are only in contact but not fixed together, and force can be transmitted between the two contacting components.

[0040] The principle of the window-breaking mechanism described above is as follows: when both the return spring 63 and the main spring 64 are in a free state, the end of the movable rod 61 contacts the tail end of the ejector pin 5, and the tip of the ejector pin 5 is located outside the window-breaking hole 2. Under the action of the main spring 64, the impact hammer 62 is located at the connection position between the rear cavity 72 and the connecting hole 4.

[0041] When the user grips the cylinder 1 and applies force with the tip of the ejector pin 5 toward the glass to be broken, the ejector pin 5 moves toward the interior of the mounting cavity 3 under the reaction force of the glass, pushing the movable rod 61 toward the impact hammer 62. Since the tail end of the movable rod 61 is biased toward the side wall of the front cavity 71, the tail end of the thin rod 612 is not in a straight line with the impact hole 621. At this time, the tail end of the thin rod 612 will pass through the connecting hole 4 under the guidance of the inclined surface 7 and contact the contact surface 622 of the impact hammer 62, causing the impact hammer 62 to move away from the connecting hole 4, and the main spring 64 is continuously compressed.

[0042] With continued force, the thick rod 611 is guided into the connecting hole 4 by the inclined surface 7. Since the connecting hole 4 has a certain thickness, it forcibly corrects the position of the entire movable rod 61, making the central axis of the movable rod 61 and the central axis of the mounting cavity 3 lie on the same straight line. At this time, the thin rod 612 is forcibly driven to slide into the impact hole 621 from the contact surface 622. Since the main spring 64 has a large elastic force when compressed, and the impact hole 621 has a certain depth, the impact hammer 62 and the thin rod 612 will form a new impact. This impact force will then react on the movable rod 61 again and push the pin 5 to move quickly toward the window breaking hole 2, thereby piercing the glass and achieving the purpose of breaking the window.

[0043] Since the ejector pin 5 always extends outside the window hole 2, to ensure that the user is not accidentally injured, this embodiment can also provide a telescopic inner cylinder 14 located inside the window hole 2 and an auxiliary spring 15 on the cylinder body 1, and the structure is as follows: Figure 3 As shown. At this time, the entire telescopic inner cylinder 14 can slide along the inner wall of the broken window hole 2, and a corresponding ejector hole for the ejector pin 5 to pass through needs to be provided on the end face of the telescopic inner cylinder 14.

[0044] The telescopic inner cylinder 14 encloses the entire ejector pin 5 within it, while the auxiliary spring 15 needs to be constantly compressed to provide a constant elastic force to the telescopic inner cylinder 14 towards the outside of the window breaker hole 2. In use, the telescopic inner cylinder 14 is pressed against the glass to be broken, and then pressed firmly. The telescopic inner cylinder 14 will then retract into the window breaker hole 2, and the ejector pin 5 will protrude from the hole. The subsequent working principle is the same as described above and will not be repeated.

[0045] The LED lighting assembly described in this embodiment consists of a mirror cover 8 located at the end of the cylindrical body 1, a PCB board located inside the cylindrical body 1, LED beads located inside the cylindrical body 1 and connected to the PCB board, a convex lens located inside the mirror cover 8, and a button 9 and a USB interface 10 located on the cylindrical body 1. Additionally, a rechargeable battery connected to the PCB board is also located inside the cylindrical body 1.

[0046] Both the button 9 and the USB interface 10 are connected to the PCB board to facilitate control of related circuits on the PCB board via the button 9, thereby controlling the lighting and extinguishing of the LED beads and the sound alarm module 17. To ensure the normal operation of the LED beads and the sound alarm module 17, corresponding LED lighting driver circuits, sound alarm driver circuits, and charging circuits need to be integrated on the PCB board.

[0047] To facilitate the focusing and divergence of light, the lens cover 8 needs to be fitted onto the front end of the cylinder 1, and the lens cover 8 can slide along the end of the cylinder 1. To facilitate real-time display of battery level, this embodiment also includes a display 11 connected to the PCB board on the cylinder 1.

[0048] To facilitate cutting seat belts, this embodiment can also provide a seat belt cutting opening 12 on the cylinder 1, and a blade 13 for cutting seat belts is provided inside the seat belt cutting opening 12. When it is necessary to cut the seat belt, simply place the seat belt into the seat belt cutting opening 12 and pull it forcefully to cut the seat belt.

[0049] The sound alarm module 17 can be any one or more combinations of a buzzer, an alarm horn, or a voice alarm. When a buzzer is selected, an electromagnetic buzzer of model SF-12055 can be used, with an operating voltage of 3-12V, a sound frequency of 2800Hz, and a clear, loud sound, reaching up to 85 decibels. If an alarm horn is selected, a high-decibel alarm horn of model YX-12065 can be used, with an operating voltage of 12V and a sound intensity of up to 110 decibels, capable of attracting attention in noisy environments. For the voice alarm, a voice chip of model WT588D-20SS can be used with a speaker, which can pre-record various voice alarm messages, such as "Help!" or "Danger!", and trigger playback through the control module to achieve a more intuitive alarm effect.

[0050] The sound alarm driver circuit is specifically designed to drive the sound alarm module 17 to emit sound, and it can be implemented using various circuit structures. Figure 4 The image shown is one type of driving circuit.

[0051] like Figure 4 As shown, the sound alarm driving circuit consists of a switch K1, a control chip U, a transistor VT1, resistors R1 and R2, a capacitor C1, and an inductor L. The switch K1 is controlled by button 9 to open and close. When connected, one end of switch K1 is connected to the positive terminal of the rechargeable battery, and the other end is grounded via resistors R1 and R2. The control chip U is implemented using a CX55 chip. Its pin 1 is grounded, its pin 2 is connected to the junction of resistors R1 and R2, its pin 3 is grounded via capacitor C1, and its pin 4 is connected to the emitter of transistor VT1. Simultaneously, pin 3 of the control chip U is connected to the base of transistor VT1. The collector of transistor VT1 is connected to the positive terminal of the rechargeable battery 41 via inductor L. The sound alarm module 17 is connected to inductor L and the collector of transistor VT1.

[0052] As can be seen from the above circuit, when button 9 drives switch K1 to close, control chip U is in working state. It will provide current to the base of transistor VT1 through its pin 3 to make transistor VT1 conduct, thereby powering on the sound alarm module 17 and emitting an alarm sound.

[0053] As described above, this utility model can be implemented well.
