Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to an electromagnetic window break alarm LED flashlight. 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 invention is to overcome the shortcomings of the current market products that do not have LED lighting, window breaking, and sound alarm functions at the same time, and to provide an electromagnetic window breaking alarm LED flashlight.

[0005] This utility model is achieved through the following technical solution: an electromagnetic window-breaking alarm LED flashlight, mainly composed of a tube body, an LED lighting component disposed on the left side of the tube body, a PCB board disposed inside the tube body, a battery disposed inside the tube body, a window-breaking component disposed on the right side of the tube body, a control switch component disposed on the tube body, and a sound alarm module disposed on the tube body; the LED lighting component, window-breaking component, battery, control switch component, and sound alarm module are all connected to the PCB board.

[0006] Furthermore, the sound alarm module is any one or more combinations of a buzzer, an alarm horn, or a voice alarm.

[0007] The window-breaking assembly includes a window-breaking hole located on the right end face of the cylinder, a ferromagnetic push plate, an electromagnet, and a main spring located inside the cylinder. The front of the ferromagnetic push plate has a striker facing the window-breaking hole. The electromagnet is fixed inside the cylinder, and the ferromagnetic push plate is located between the electromagnet and the window-breaking hole and can slide along the inner wall of the cylinder. When compressed, the main spring provides a spring force to the ferromagnetic push plate to move towards the window-breaking hole. The electromagnet is connected to a control switch assembly.

[0008] The control switch assembly includes a first switch, a second switch, a third switch, and a fourth switch. The first and second switches are used to control the electromagnet to turn on or off. The third switch is connected to the PCB board and is used to control the LED lighting assembly to turn on or off. The fourth switch is used to control the sound alarm module to turn on or off.

[0009] As a preferred embodiment, a return spring and a window housing with a closed end and an open end are provided inside the window opening; the closed end of the window housing extends to the outside of the window opening and is provided with a through hole corresponding to the striker, and the open end of the window housing is located inside the window opening, and the entire window housing can slide along the inner wall of the window opening; the return spring is used to provide elastic force to the window housing to move in the direction of the window opening when compressed.

[0010] The LED lighting assembly consists of a mirror cover located at the end of the cylinder, LED beads located inside the cylinder, and a light-transmitting plate located inside the mirror cover; the LED beads are connected to the PCB board via wires.

[0011] The light-transmitting plate is a convex lens, and the distance between the light-transmitting plate and the LED beads can change as the lens cover rotates or slides.

[0012] To facilitate the display of power and other relevant information, a display connected to the PCB board is also provided on the cylinder.

[0013] To facilitate cutting seat belts, a seat belt cutting opening is provided on the cylinder, and a blade for cutting seat belts is provided inside the seat belt cutting opening.

[0014] The electromagnet's attraction force is greater than the spring force of the main spring.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] (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.

[0017] (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.

[0018] (3) This utility model uses an electromagnet as the core component for breaking windows. When it is energized, it can generate a stable adsorption force to hold the ferromagnetic push plate and compress the spring to the maximum extent. When it is de-energized, under the action of the spring, it can instantly push the ferromagnetic push plate towards the window hole, so that the impact pin on the ferromagnetic push plate can break the glass and realize the window breaking function. Not only is its window breaking impact force stable, but it can also be reused.

[0019] (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 electromagnetic window-breaking alarm LED flashlight described in this embodiment mainly consists of a cylinder 1, an LED lighting component 2 disposed on the left side of the cylinder 1, a PCB board 3 disposed inside the cylinder 1, a battery 4 disposed inside the cylinder 1, a window-breaking component 5 disposed on the right side of the cylinder 1, a control switch component 6 disposed on the cylinder 1, and a sound alarm module 12 disposed on the cylinder 1. The cylinder 1 can be made of materials such as metal or engineering plastics. The left and right sides of the cylinder 1 are determined by its placement. For example, if the LED lighting component 2 is disposed on the left side of the cylinder 1, it will be located on the right side when the cylinder 1 is placed in a different orientation. Therefore, the left and right sides of the cylinder 1 in this embodiment are interchangeable.

[0030] The aforementioned window-breaking assembly 5 is a device for breaking windows, comprising a window-breaking hole 51 located on the right end face of the cylinder 1, a ferromagnetic push plate 52, an electromagnet 53, and a main spring 54 disposed inside the cylinder 1. The ferromagnetic push plate 52 is an iron plate whose shape matches the internal shape of the cylinder 1, and it has two sides. For ease of description and explanation, in this embodiment, the side facing the window-breaking hole 51 is referred to as the front side, and the side facing away from the window-breaking hole 51 is referred to as the back side. The entire ferromagnetic push plate 52 can slide freely along the inner wall of the cylinder 1. A striking pin 55 is provided on the front side of the ferromagnetic push plate 52, and the striking pin 55 is positioned directly opposite the window-breaking hole 51 to ensure that the ferromagnetic push plate 52, under the action of the main spring 54, can drive the striking pin 55 through the window-breaking hole 51 and act on the external glass.

[0031] The electromagnet 53 is fixed inside the cylinder 1, while the ferromagnetic pusher plate 52 is located between the electromagnet 53 and the window hole 51. The main spring 54, when compressed, provides a spring force to the ferromagnetic pusher plate 52, causing it to move towards the window hole 51. In a specific connection, one end of the main spring 54 is fixed to the electromagnet 53, and the other end is fixedly connected to the back of the ferromagnetic pusher plate 52. Alternatively, the main spring 54 can simply be positioned between the electromagnet 53 and the back of the ferromagnetic pusher plate 52 without being fixed, as long as the main spring 54 can be compressed by the ferromagnetic pusher plate 52 under the attraction of the electromagnet 53.

[0032] The electromagnet 53 consists of an iron core and a coil wound around the iron core. The coil needs to be connected to the control switch assembly 6 to ensure that the electromagnet 53 can be turned on and off by controlling the switch assembly 6.

[0033] The control switch assembly 6 includes a first switch 61, a second switch 62, a third switch 63, and a fourth switch 64. The first and second switches 61 and 62 control the on / off state of the electromagnet 53, the third switch 63 controls the on / off state of the LED lighting assembly 2, and the fourth switch 64 controls the on / off state of the sound alarm module 12. Specifically, the first and second switches 61 and 62 can be directly connected in series in the coil circuit, or they can be connected to the PCB board 3 to control the on / off state of the electromagnet 53 through relevant circuit structures on the PCB board 3. The third switch 63 is connected to the PCB board 3 to control the LED lighting assembly 2. The fourth switch 64 is set in... Figure 5 The sound alarm drive circuit shown is used in this circuit.

[0034] As a preferred embodiment, the first switch 61 is a normally open switch, preferably located inside the cylinder 1 and within the travel path of the ferromagnetic push plate 52; the second switch 62 is a normally closed switch, located on the outer surface of the cylinder 1. The first switch 61 and the second switch 62 are connected in series and integrally connected to the coil circuit of the electromagnet 53, or the first switch 61 and the second switch 62 are respectively connected to the relevant functional circuits on the PCB board 3, thereby realizing the function of controlling the opening or closing of the electromagnet 53.

[0035] The working principle of the above structure is as follows: when the window-breaking function is not used, the main spring 54 is in a free state, the ferromagnetic push plate 52 is located on one side of the window-breaking hole 51, and the striker 55 is located outside the window-breaking hole 51. When the striker 55 is pressed against the glass to be broken, the striker 55, under the reaction force of the glass, will drive the ferromagnetic push plate 52 to the side of the electromagnet 53, and the main spring 54 will be gradually compressed. When the ferromagnetic push plate 52 presses against the first switch 61, the circuit between the coil of the electromagnet 53, the first switch 61, the second switch 62 and the battery 4 is turned on, the electromagnet 53 is energized, and a strong attraction force is generated, thereby overcoming the elastic force of the main spring 54 and attracting the ferromagnetic push plate 52 to the electromagnet 53, and the main spring 54 is compressed to its maximum extent. When the user presses or touches the second switch 62, the circuit between the coil of the electromagnet 53, the first switch 61, the second switch 62 and the battery 4 is disconnected. The electromagnet 53 loses power, and the strong attraction force it generates disappears instantly. The ferromagnetic push plate 52 moves instantly toward the window breaking hole 51 under the elastic force of the main spring 54, thereby driving the striker 55 to pass through the window breaking hole 51 and act on the glass, thus realizing the window breaking function.

[0036] As a second preferred embodiment, the first switch 61 is a normally open switch and the second switch 62 is a normally closed switch. Both the first switch 61 and the second switch 62 are located on the outer side of the cylinder 1, so that the user can manually control the first switch 61 and the second switch 62 respectively.

[0037] The working principle of the above-mentioned priority mode two is as follows: when the window-breaking function is not used, the main spring 54 is in a free state, the ferromagnetic push plate 52 is located on one side of the window-breaking hole 51, and the striker 55 is located outside the window-breaking hole 51. When the first switch 61 is pressed, the circuit between the coil of the electromagnet 53, the first switch 61, the second switch 62 and the battery 4 is turned on, the electromagnet 53 is energized, and a strong attraction force is generated, thereby overcoming the elastic force of the main spring 54 and attracting the ferromagnetic push plate 52 onto the electromagnet 53, and the main spring 54 is compressed to its maximum extent. When the user presses or touches the second switch 62, the circuit between the coil of the electromagnet 53, the first switch 61, the second switch 62 and the battery 4 is disconnected, the electromagnet 53 is de-energized, and the strong attraction force it generated disappears instantly. Under the elastic force of the main spring 54, the ferromagnetic push plate 52 moves instantaneously towards the window-breaking hole 51, thereby driving the striker 55 to pass through the window-breaking hole 51 and act on the glass, thus realizing the window-breaking function.

[0038] Since the ferromagnetic push plate 52 may be pressed tightly against the window hole 51 when the electromagnet 53 is not energized, causing the striking pin 55 to protrude outside the window hole 51 and potentially leading to an accident, a protective device can also be installed inside the window hole 51 in this embodiment. This protective device consists of a return spring 7 and a window hole housing 8, and its overall structure is as follows: Figure 4As shown. The window-breaking housing 8 has a closed end and an open end, with a through hole 81 corresponding to the striking pin 55 on the closed end. The closed end of the window-breaking housing 8 extends outside the window hole 51, while its open end is located inside the window hole 51 and close to the front of the ferromagnetic push plate 52. The entire window-breaking housing 8 can slide along the inner wall of the window hole 51. The function of the return spring 7 is to provide a spring force to the window-breaking housing 8 towards the window hole 51 when compressed. Specifically, one end of the return spring 7 is connected to the inner wall of the cylinder 1, and the other end is connected to the open end of the window-breaking housing 8, thereby providing a continuous thrust towards the outside of the window hole 51 to ensure that the window-breaking housing 8 can enclose the striking pin 55 when not in use, preventing accidental injury to the user. Alternatively, one end of the return spring 7 is connected to the front of the ferromagnetic push plate 52, and the other end is connected to the open end of the broken window housing 8. In this case, the elastic force of the main spring 54 is greater than the elastic force of the return spring 7.

[0039] With the protective device in place, the working principle is as follows: when the window-breaking function is not used, the window-breaking housing 8, under the action of the return spring 7, always encloses the striker 55 inside, preventing the striker 55 from being outside the through hole 81. When the window-breaking function is to be used, the window-breaking housing 8 is pressed firmly against the glass to be broken. At this time, under the reaction force of the glass, the window-breaking housing 8 will move towards the inside of the window-breaking hole 51, so that the striker 55 passes through the through hole 81 and contacts the glass. Under the reaction force of the glass, the striker 55 will drive the ferromagnetic push plate 52 to move towards the electromagnet 53. The subsequent working principle is the same as described above and will not be repeated. After the window is broken, when the user removes the applied force, under the action of the return spring 7, the window-breaking housing 8 will be pushed back to the outside of the window-breaking hole 51, enclosing the striker 55 inside again.

[0040] The battery 4 is preferably a rechargeable battery, while the PCB board 3 serves as a carrier integrating several functional circuits. The battery 4 is connected to the PCB board 3, meaning the battery 4 is connected to the relevant functional circuits integrated on the PCB board 3 to provide operating current and voltage for the normal operation of each functional circuit. In this embodiment, the PCB board 3 needs to be equipped with at least an LED driving circuit for driving the LED lighting component 2 to turn on or off, a charging circuit for charging and protecting the battery 4, and a sound alarm driving circuit for driving the sound alarm module 12 to start or stop. When a display 9 is installed on the cylinder 1, a corresponding display driving circuit for the display 9 also needs to be installed on the PCB board 3. The overall circuit structure of the PCB board 3 is as follows: Figure 3 As shown.

[0041] The sound alarm module 12 can be any one or a combination 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.

[0042] The LED lighting assembly 2 consists of a mirror cover 21 located at the end of the cylindrical body 1, LED beads 22 located inside the cylindrical body 1, and a light-transmitting plate 23 located inside the mirror cover 21. The LED beads 22 are used to emit light and are connected to the LED driving circuit in the PCB board 3 through wires.

[0043] The sound alarm driving circuit is as follows Figure 5 As shown, it consists of switch K1, control chip U, transistor VT1, resistors R1 and R2, capacitor C1, and inductor L. Switch K1 is the fourth switch 64. When connected, one end of switch K1 is connected to the positive terminal of battery 4, and the other end is grounded after passing through resistors R1 and R2. Control chip U is implemented using a CX55 chip. Its pin 1 is grounded, pin 2 is connected to the junction of resistors R1 and R2, pin 3 is grounded after passing through capacitor C1, and pin 4 is connected to the emitter of transistor VT1. Simultaneously, pin 3 of control chip U is connected to the base of transistor VT1. The collector of transistor VT1 is connected to the positive terminal of battery 4 after passing through inductor L. The sound alarm module 12 is connected to inductor L and the collector of transistor VT1.

[0044] As can be seen from the above circuit, when the fourth switch 64 (switch K1) is closed, the control chip U is in working state. It will provide current to the base of the transistor VT1 through its pin 3 to make the transistor VT1 conduct, thereby energizing the sound alarm module 12 and emitting an alarm sound.

[0045] To better achieve the zoom function, the light-transmitting plate 23 is implemented using a convex lens, and the lens cover 21 can slide along the end of the cylinder 1, meaning the lens cover 21 can move relative to the end of the cylinder 1. Since the light-transmitting plate 23 is fixedly connected to the lens cover 21, when the distance between the lens cover 21 and the end of the cylinder 1 changes, the distance between the convex lens and the LED bead 22 can be changed, thereby achieving light focusing and divergence. Similarly, the lens cover 21 can also be connected to the end of the cylinder 1 by rotation. That is, after the lens cover 21 is connected to the end of the cylinder 1, the lens cover 21 or its components can rotate relative to the cylinder 1, thereby changing the distance between the light-transmitting plate 23 and the LED bead 22, achieving the zoom function. This technology is mature and will not be elaborated further.

[0046] Meanwhile, to facilitate cutting the seat belt, a seat belt cutting slot 10 is provided on the cylinder 1, and a blade 11 for cutting the seat belt is provided inside the seat belt cutting slot 10. When it is necessary to cut the seat belt, simply put the seat belt into the seat belt cutting slot 10 and pull it forcefully to cut the seat belt.

[0047] As described above, this utility model can be implemented well.
