Description

Technical Field

[0002] In the event of an emergency, the seatbelts may malfunction and become unusable, and the doors and power windows may also be unable to open. In such cases, an emergency tool needs to be stored in the vehicle for immediate use. However, existing emergency sticks are mainly used for lighting and have a limited function. Although some multi-section emergency sticks integrate tools such as cutting knives and window breaker hammers, the integration method involves integrating the cutting knife and window breaker hammer into different sections of the stick. This not only results in a long overall structure that is difficult to store, but also makes it difficult for users to accurately locate the required tool from the multiple sections in an emergency, potentially wasting valuable escape time.

[0067] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0068] When a component is considered to be "located" on another component, it can be directly on the other component or may also be interspersed with other components. When a component is considered to be "connected" to another component, it can be directly connected to the other component or may also be interspersed with other components.

[0069] It's understandable that the term "perpendicular" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately perpendicular. For example, combined with numerical descriptions, perpendicularity can refer to the angle between two straight lines within the range of 90° ± 10°, the dihedral angle between two planes within the range of 90° ± 10°, or the angle between a straight line and a plane within the range of 90° ± 10°. The two components described as "perpendicular" do not have to be absolutely straight lines or planes; they can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is straight or plane, the component can be considered a "straight line" or "plane."

[0070] Unless otherwise defined, the term "multiple" in this document, when used to describe the number of components, specifically means that the component is two or more.

[0071] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0072] In the field of vehicle emergency tools, there has long been a contradiction between limited functionality and complex operation. Traditional emergency sticks typically employ a multi-section, serially connected structure, distributing tools such as window breakers and cutting knives across different segments, resulting in an overall length exceeding portability. When encountering dangerous situations such as locked doors or windows that cannot be opened, users must disassemble the stick section by section to obtain the necessary tools. This not only delays rescue efforts but also increases the risk of tool misselection in dark environments.

[0073] Example 1

[0074] Please refer to Figures 1-8 This application proposes a multi-functional emergency stick comprising three functional modules: the first module 10 integrates a power supply component 11 and a safety warning component 12; the second module 20 has a built-in water treatment component 21; and the third module 30 is provided with a demolition component 31 and an expansion component 32. The first module 10 forms a detachable combination structure through the second module 20 and the third module 30. The first module 10 is provided with a connection port corresponding to the expansion component 32, so that the power supply component 11 and the expansion component 32 are electrically connected.

[0075] Among them, the power supply component 11 refers to a device that provides power conversion and distribution functions, which can be implemented by a combination of energy storage battery and circuit control board; this component provides a stable power supply to each module functional unit through centralized power supply, solving the energy redundancy problem caused by multiple power supply systems in traditional equipment; the safety warning component 12 refers to a device with audible and visual alarm functions, which can be implemented by a combination of LED light source 1211 and piezoelectric ceramic buzzer 122; this component enhances the environmental perception capability in emergency scenarios through visual and audible warning signals; the water treatment component 21 refers to a device that achieves water filtration and purification, which can be implemented by a combination of activated carbon adsorption and physical filtration. The modular design ensures independent operation of the drinking water acquisition function. The demolition component 31 is a device for performing mechanical demolition operations, specifically a combination of a spring-loaded impact head and a high-hardness alloy blade. This component avoids interference through its independent module layout. The expansion component 32 is a device for power replenishment and external power supply, specifically a combination of a multi-interface charging cable 321 and an external power adapter. This component establishes an extended power supply channel through connection ports. The detachable assembly structure refers to the mechanical connection between modules using threaded connections and snap-fit ​​fixings. This structure allows for on-demand configuration of functional modules through a quick assembly / disassembly mechanism.

[0076] Specifically, the three functional modules are connected axially to form a rod-shaped main body; the first module 10 serves as the power supply hub, and its internal battery pack outputs power to other modules through the connection port; when a window breaking operation is required, the third module 30 forms an emergency tool with breaking and dismantling functions; when drinking water is needed, the second module 20 can be disassembled independently as a portable water filtration device; the connection ports between the modules adopt a standard interface design to ensure that the expansion component 32 can be used across modules; this modular layout allows each functional unit to operate independently and to form functional synergy through combination.

[0077] Compared with existing technologies, traditional emergency tools use a linearly arranged rod structure, and the linear distribution of each tool unit results in an excessively long operating distance. This solution uses a modular reconfiguration design to concentrate frequently used functions in the first module 10. Furthermore, the fixed connection method of traditional emergency sticks limits their functional expandability. This solution uses a detachable interface design to expand the functional modules.

[0078] Through the above technical solutions, this application effectively solves the problems of difficult tool positioning and slow function switching in emergency scenarios; the modular structure design makes the physical location of each functional unit clear, and the target module can be quickly identified by touch in a dark environment; the detachable connection mechanism allows the selection of core functional modules according to the type of danger, avoiding the waste of space caused by carrying redundant components; the power supply component 11, together with the expansion interface, can not only ensure the stable operation of basic functions, but also expand external devices as needed, significantly improving the scenario adaptability of emergency equipment.

[0079] Example 2

[0080] Please refer to Figures 1-4 This application further proposes a power supply component 11 including a fixed bracket 111, an energy storage unit 112, a PCB control board 113, and a charging / discharging interface 114; the energy storage unit 112 is fixedly installed in the first module 10 via the fixed bracket 111; the PCB control board 113 is fixedly disposed on one side of the fixed bracket 111, and the energy storage unit 112 is configured to be charged and discharged through the PCB control board 113; the charging / discharging interface 114 is disposed on the PCB control board 113, and the charging / discharging interface 114 is configured to be connected to the safety warning component 12 or the expansion component 32 for power supply; or, the charging / discharging interface 114 is configured to charge a high-density battery.

[0081] Among them, the fixed bracket 111 refers to the structural component used to support and fix the energy storage unit 112, which can be implemented by an aluminum alloy frame or an injection-molded support skeleton. Its function is to prevent the energy storage unit 112 from shifting under vibration. The energy storage unit 112 refers to the device for storing electrical energy, which can be implemented by a lithium-ion battery or a nickel-metal hydride battery pack. Its function is to provide power supply for the core functional module. The PCB control board 113 refers to the substrate that integrates the charging and discharging management circuit. It can be implemented by surface mount technology to solder the control chip and protection circuit. Its function is to realize power distribution and load balancing. The charging and discharging interface 114 refers to the connector used to connect external devices or chargers. It can be implemented by a USB-C interface or a spring pin contact. Its function is to expand the power supply function and be compatible with various external devices.

[0082] Compared to existing technologies, traditional emergency power supply modules typically use loose wiring, with the battery and control circuit connected only by wires, posing a risk of poor contact. This solution, however, uses a mounting bracket 111 to rigidly fix the energy storage unit 112 to the PCB control board 113, eliminating the risk of wires coming loose due to vibration. Existing technologies have single-function charging interfaces that cannot simultaneously meet the needs of device power supply and battery charging. This solution utilizes a reused charging / discharging interface 114 to enable bidirectional current transmission from a single interface.

[0083] Through the above technical solution, this application solves the problem of the emergency stick's power supply system being loosely structured and easily damaged. The integrated layout of the fixed bracket 111 and the PCB control board 113 improves the stability of power supply. The bidirectional current design of the charging and discharging interface 114 enables the emergency stick to be used as a mobile power source and to quickly replenish its own power, allowing for flexible switching between multiple power supply modes in emergency scenarios.

[0084] Example 3

[0085] Please refer to Figures 1-4 This application further proposes a safety warning component 12 including a lighting device 121 and a buzzer 122. The lighting device 121 is located at the front end of the first module 10, and the buzzer 122 is located at the rear end of the first module 10. The lighting device 121 and the buzzer 122 are electrically connected to the PCB control board 113 respectively.

[0086] The lighting device 121 refers to the component used to provide a visible light source 1211, which can be implemented by encapsulating LED beads on a fixed bracket 111. Its placement at the front end enables directional beam projection. The buzzer 122 refers to the component used to emit an alarm sound, which can be implemented by installing a piezoelectric buzzer 122 in the rear cavity. Its placement at opposite ends from the lighting device 121 avoids sound and light interference. The PCB control board 113 refers to the circuit board used for power distribution and function control. It can be implemented by connecting to the functional components by soldering wires, and it can synchronously control the lighting brightness and buzzer frequency.

[0087] Specifically, the front-end lighting device 121 is independently powered by the PCB control board 113 and can provide continuous lighting or flashing warning in emergency situations; the rear-end buzzer 122 is connected to the PCB control board 113 through an independent circuit and can emit intermittent or continuous alarm sounds according to instructions; the design of placing the two at opposite ends of the module optimizes the spatial layout, so that the sound and light signals of the warning function do not interfere with each other; when the operator holds the first module 10, the front-end lighting can be aimed at the target area, and the sound waves generated by the rear-end buzzer 122 spread towards the back of the holder, forming a 360-degree warning coverage range.

[0088] Compared with existing technologies, traditional emergency tools often integrate lighting and sound devices in the same location, which can easily lead to mutual interference between sound and light signals. However, by placing the lighting device 121 and the buzzer 122 at opposite ends of the module, the impact of sound wave vibration on the stability of the light source 1211 is avoided, and the sound and light signals are propagated in different directions, which significantly improves the reliability and coverage of the warning function. In addition, the independent circuit design of the PCB control board 113 allows the sound and light warnings to be activated individually or in combination to meet the emergency needs of different scenarios.

[0089] Through the above technical solution, this application effectively solves the problems of single warning function and mutual interference between sound and light signals in traditional emergency tools. The separate layout of the front-end lighting and the rear-end buzzer 122 allows the operator to control the direction of the sound and light warning with one hand. In enclosed spaces such as vehicle accidents, it can simultaneously provide escape route lighting and location distress signals. The power distribution function of the PCB control board 113 ensures that the core warning function is maintained first when the power is low, significantly improving the chances of survival in emergency situations.

[0090] Example 4

[0091] Please refer to Figures 1-4 This application further proposes a lighting device 121 including a light source 1211, a condenser lens 1213, and a reflector 1215. The light source 1211 is encapsulated on a fixed bracket 111. The front end of the first module 10 is provided with a light-emitting hole 1213 corresponding to the light source 1211. A receiving recess 1214 is provided along the outer side of the light-emitting hole 1213. The condenser lens 1213 is disposed in the receiving recess 1214, and the optical axis of the condenser lens 1213 coincides with the optical axis of the light source 1211. The reflector 1215 is threaded to the inner side of the front end of the first module 10. The bottom of the reflector 1215 abuts against the condenser lens 1213 to fix the condenser lens 1213 in the receiving recess 1214.

[0092] The light source 1211 refers to the light-emitting element, which can be implemented using LED beads or halogen bulbs. Its stable position is ensured by being encapsulated on the mounting bracket 111. The condenser lens 1213 is a transparent optical element used to focus the light beam, which can be implemented using a convex lens or Fresnel lens. The light is collimated and output through an optical axis coincidence design. The reflector cup 1215 is a cup-shaped structure with a reflective surface, which can be implemented using a metal plating or vacuum coating process. It is connected to the front end of the module via a threaded connection, forming a detachable and fixed structure that ensures the installation stability of the condenser lens 1213 and facilitates maintenance and replacement.

[0093] Specifically, the light source 1211 is precisely mounted at a predetermined position on the fixed bracket 111, and the light emission aperture 1213 is aligned with the light source 1211 to ensure light emission efficiency. The condenser lens 1213 achieves rapid positioning through the limiting structure of the receiving recess 1214, and the optical axis coincidence design prevents beam deviation. The reflector cup 1215 is connected to the front end of the module by a threaded insertion method. During tightening, the bottom end face presses against the condenser lens 1213, forming a three-point fixing structure. This assembly method requires no additional fasteners and can maintain the structural stability of the optical components even in emergency situations.

[0094] Example 5

[0095] Please refer to Figures 1-4This application further proposes that the first module 10 of the multifunctional emergency stick has a cylindrical structure, and the front end of the first module 10 is provided with several positioning protrusions 14, and the rear end of the first module 10 is provided with a threaded connection structure.

[0096] The cylindrical structure refers to a hollow cylindrical shell, which can be injection molded from metal or high-strength plastic. Its internal space is configured to accommodate the power supply component 11 and the safety warning component 12. This structure improves the docking accuracy between modules by maintaining axial symmetry. The positioning protrusion 14 refers to a trapezoidal protrusion evenly distributed along the circumference. It can be implemented by a reinforcing rib structure integrally formed with the first module 10. Its height can be set to the range of 0.5-2 mm. It is used to form a mechanical interlock with the inner wall groove of the adjacent module. The threaded connection structure refers to a spiral groove set on the outer surface. It can be implemented by a single-thread or double-thread design. The thread angle can be set to 55 degrees or 60 degrees. It is used to achieve axial fixation between the second module 20 and the first module 10.

[0097] Specifically, the cylindrical structure is configured to form a standardized docking base through axial extension. Its front positioning protrusion 14 cooperates with the limiting groove of the protective shell 33 to achieve phase positioning during rotation. When the first module 10 is assembled with the protective shell 33, the positioning protrusion 14 guides the protective shell 33 to align at a preset angle, and then the protective shell 33 is locked to the first module 10 by rotation. This structure allows the modules to be fastened by rotating only 90-180 degrees, which significantly improves the assembly efficiency compared to the traditional multi-segment rod that requires multiple rotations.

[0098] Example 6

[0099] Please refer to Figures 1-4 This application further proposes that the first module 10 includes a heating component 13, which includes a heating layer 131 and a heat storage layer 132. The heating layer 131 is disposed on the outer periphery of the first module 10 and connected to the power supply component 11. The heat storage layer 132 covers the outer side of the heating layer 131. The heating structure of the hand warmer uses an electric heating wire, which generates heat after being powered on and is transferred to the heat storage layer 132.

[0100] Among them, the heating layer 131 refers to the component used to convert electrical energy into heat energy, which can be implemented by metal resistance wire or semiconductor heating element. After being connected to the power supply component 11, it can generate heat through current. The heat storage layer 132 refers to the component used to store and slowly release heat, which can be implemented by phase change material or metal shell with high specific heat capacity. It covers the outside of the heating layer 131 and can evenly transfer heat to the outside. The electric heating wire refers to the linear or strip conductor that works on the principle of resistance heating. It can be made of nickel-chromium alloy or iron-chromium-aluminum alloy material. After being energized, it generates heat through the Joule effect.

[0101] Specifically, a heating layer 131 is installed around the outer periphery of the first module 10. The heating layer 131 is electrically connected to the internal power supply component 11. When the user needs heating, the heating layer 131 is activated, and electrical energy is converted into heat energy through the electric heating wire. The heat is transferred to the heat storage layer 132 covering the outside of the heating layer 131. After absorbing the heat, the heat storage layer 132 slowly releases it through its surface, forming a continuous heating effect. The heating layer 131 is arranged in a ring around the outer periphery of the first module 10, which does not affect the layout of other components inside the module and can form a surrounding heat radiation. The outer layer of the heat storage layer 132 may be provided with a heat insulation layer to prevent heat from being lost too quickly.

[0102] Compared with existing technologies, traditional emergency sticks only have lighting and demolition functions and cannot provide warmth support in cold environments. This solution integrates a heating layer 131 and a heat storage layer 132 on the outer periphery of the first module 10, and achieves rapid heating through the power supply component 11, expanding the temperature regulation capability while ensuring the basic functions of the emergency tool. Compared with external heating devices, this solution adopts an integrated structural design, with the heating layer 131 sharing the power supply system with the main body of the emergency stick, avoiding the need to carry additional equipment.

[0103] Through the above technical solution, this application can provide emergency heating function when the vehicle breaks down or encounters danger in the wild. The heat storage layer 132 extends the heating duration. The integrated design of the heating layer 131 and the power supply component 11 avoids the expansion of the functional module and ensures that the emergency rod maintains a compact shape. The heat conversion efficiency of the electric heating wire can meet the requirements of rapid heating. At the same time, the temperature buffering effect of the heat storage layer 132 prevents the surface from overheating and causing burns.

[0104] Example 7

[0105] Please refer to Figures 5-6 This application further proposes that the second module 20 is configured as a variable diameter sleeve with a gradually decreasing outer diameter, and the inner side of the front end of the variable diameter sleeve is provided with a connecting thread;

[0106] The water treatment component 21 includes a filter element 211 and a water collection pipe 212. The filter element 211 is fixed by a sleeve 213 and the water collection pipe 212. The outer wall of the sleeve 213 is provided with several protruding ridges, which elastically abut against the inner wall of the second module 20.

[0107] Among them, filter element 211 refers to the component used to filter impurities in water, which can be implemented by activated carbon filter element or ceramic filter element. Activated carbon filter element removes odor and organic matter through adsorption, while ceramic filter element intercepts suspended particles through microporous structure; water collection pipe 212 refers to the component used to collect and transport filtered water flow, which can be implemented by hollow tubular structure. Its internal channel is connected to filter element 211 to ensure that water flows into water collection pipe 212 after filtration; sleeve 213 refers to the connecting component used to fix filter element 211 and water collection pipe 212, which can be implemented by cylindrical structure with open ends. Filter element 211 is inserted into one end of sleeve 213, and water collection pipe 212 is inserted into the other end of sleeve 213. Quick assembly is achieved by sleeve connection; ridge refers to the strip-shaped raised structure set on the outer wall of sleeve 213, which can be implemented by ring or spiral arrangement of raised strips. The ridge forms elastic contact with the inner wall of the second module 20 to provide radial support force to prevent sleeve 213 from loosening.

[0108] Furthermore, the filter element 211 is any one or a combination of PP cotton filter element, activated carbon filter element, hollow fiber filter element, and ceramic filter element; wherein, the PP cotton filter element removes large particulate impurities in the water, such as silt, rust, and suspended solids, through the physical interception effect of polypropylene fibers, and can effectively protect subsequent filter elements from clogging and damage by large particulate impurities; the activated carbon filter element refers to a filter structure made of activated carbon material, specifically it can be realized by compressed molding or granular filled activated carbon blocks, and its internal pore structure can adsorb odors, discoloration, organic matter, and salt in the water; the hollow fiber filter element removes bacteria, viruses, colloids, and other tiny particles in the water through the principle of microporous filtration; the ceramic filter element refers to a porous filter structure formed by sintering diatomaceous earth or ceramic powder, specifically it can be realized by using ceramic filter elements with a pore size of 0.1-0.5 microns, and its physical interception effect can remove salt, suspended particles, and bacteria in the water.

[0110] Please refer to Figure 1 , Figures 7-8 This application further proposes that the demolition component 31 includes a window breaker 311, which is fixedly mounted on the third module 30, and the elastic trigger part of the window breaker 311 protrudes from the third module 30.

[0111] Among them, the window breaker 311 refers to a device that breaks glass by mechanical impact. Specifically, it can be achieved by using an impact pin with a spring energy storage structure. The impact pin is locked by a buckling mechanism in the pre-pressed state and releases impact energy when the elastic trigger part is pressed. The elastic trigger part protruding from the third module 30 means that the operating end of the trigger mechanism extends beyond the surface of the module protective shell 33. The protruding design allows the operator to quickly activate the window breaking function in an emergency without having to accurately locate the trigger position.

[0112] Specifically, the window breaker 311 is mounted at the end of the third module 30 via a fixed base, with its impact direction parallel to the module's axis. The elastic trigger protrudes approximately 10-15 mm from the module surface, forming a perceptible physical protrusion. When breaking the window, the operator directly presses the elastic trigger against the window glass, releasing the internal spring locking mechanism. The spring then releases energy to drive the impact pin, shattering the glass. This design aligns the trigger action with the module's grip direction, facilitating one-handed operation.

[0113] This solution integrates the window breaker 311 directly into the end of the module with the trigger exposed. The operator does not need to disassemble the component or search for the tool. In emergency situations such as vehicle rollover or flooding, blind operation triggering can be achieved. This application solves the problem of difficult positioning of the window breaker 311 caused by the dispersed structure of existing emergency tools. The exposed elastic trigger structure realizes rapid window breaking operation, avoiding delays in escape opportunities due to tool search and unlocking steps in emergency escape scenarios, and significantly improving the functional integration and operational reliability of emergency equipment.

[0114] Example 9

[0115] Please refer to Figure 1 , Figures 7-8 This application further proposes that the demolition component 31 includes a cutting blade 312, which is disposed in the barb 313 of the third module 30. The barb 313 has a guide surface 314 in the opening direction, which is used to guide the object to be cut to slide toward the cutting blade 312.

[0116] Among them, the barb 313 refers to the hook-shaped structure that bends inward at the end of the third module 30. It can be made of metal or high-strength plastic in one piece. Its internal space is configured to accommodate the cutting blade 312. The guide surface 314 refers to the inclined surface that extends from the opening edge of the barb 313 toward the cutting blade 312. It can be made of arc or wedge structure. It guides the object being cut to move along a predetermined path through physical contact.

[0117] Specifically, the cutting blade 312 is fixed inside the barb 313, and the opening direction of the barb 313 is consistent with the external operating direction. When the user uses the demolition component 31 to cut an object, the object contacts the guide surface 314 at the opening of the barb 313. Under the action of the tilt angle of the guide surface 314, the object is guided to slide towards the cutting blade 312. The cutting blade 312 is fixed in position, and the user does not need to manually adjust the cutting angle. Through the cooperation of the barb 313 and the guide surface 314, the cutting operation is constrained to a single direction, avoiding the risk of reduced cutting efficiency or tool slippage due to operation deviation. The guiding effect of the guide surface 314 reduces the dependence on operating precision, making the cutting action easier to execute, especially improving the reliability of operation in emergency situations.

[0118] Example 10

[0119] Please refer to Figure 1 , Figures 7-8 This application further proposes that the expansion component 32 includes a charging cable 321 and an igniter 322; the charging cable 321 is snapped into the receiving groove on the side of the barb 313, and the interface of the charging cable 321 includes one or more of a Type-C interface, a Lightning interface or a MicroUSB interface; the igniter 322 is snapped into the arc-shaped guide groove of the third module 30.

[0120] The receiving groove on the side of the barb 313 refers to the groove structure set on the outside of the barb 313. Specifically, it can be integrally processed with the barb 313 using injection molding process, and is used to limit the displacement of the charging cable 321 in the groove. The multi-type interface of the charging cable 321 refers to the charging connectors of different specifications integrated at the end of the cable. Specifically, the connectors can be fixed to the cable using in-mold injection molding process, and is used to adapt to the charging needs of different electronic devices. The arc-shaped guide groove refers to the curved groove opened on the surface of the third module 30. Specifically, it can be manufactured simultaneously with the module shell using hot pressing molding process, and is used to constrain the placement angle and access path of the igniter 322.

[0121] Specifically, the charging cable 321 is confined within the receiving groove on the side of the barb 313, and a physical snap-fit ​​is achieved by matching the depth of the groove with the diameter of the cable, so that the cable remains in a fixed position when the emergency stick is shaken; multiple types of interfaces are integrated by integrating multiple standard connectors, such as Type-C and Lightning dual interfaces, so that cross-device compatibility can be achieved on a single charging cable 321; after the igniter 322 is embedded in the arc-shaped guide groove, its arc-shaped contour and the inner wall of the guide groove form a three-point positioning, ensuring that the igniter 322 slides out along a preset trajectory when pulled out with one hand in an emergency.

[0122] Example 11

[0123] Please refer to Figure 1 , Figures 7-8 This application further proposes that the third module 30 also includes a protective shell 33, which is sleeved on the outside of the demolition component 31 and the expansion component 32. The bottom inner side of the protective shell 33 is snapped and fixed to the rear outer side of the second module 20. The top of the protective shell 33 is provided with a north arrow 34 for indicating due north when the protective shell 33 is placed vertically.

[0124] The protective shell 33 refers to the shell structure that encloses the demolition component 31 and the expansion component 32. It can be injection molded from a high-toughness plastic material, integrating the functional components internally through an encapsulated layout to avoid positioning difficulties caused by scattered tools. The snap-fit ​​fixing refers to the connection between the bottom of the protective shell 33 and the second module 20 via a snap-fit ​​structure. This can be achieved using a combination of elastic protrusions and grooves to enhance the connection stability between modules and prevent components from falling off. The compass 34 is a freely rotatable magnetic needle-type direction indicator. It can be embedded in a groove at the top of the protective shell 33 and sealed with a transparent protective cover. It automatically calibrates to point to true north in a vertical position using gravity. It can be implemented using a magnetic needle or an electronic compass, for example, by embedding a sealed cavity with a magnetized pointer at the top of the protective shell 33.

[0125] Furthermore, the protective shell 33 is made of a semi-transparent material and is fixed to the front end of the first module 10 by a snap-fit ​​method, so that the lighting device 121 and the protective shell 33 together form a warning light structure. The light is scattered by the semi-transparent material. At the same time, a compass 34 is integrated on the top of the protective shell 33, which automatically displays the direction when the protective shell 33 is placed vertically.

[0126] Among them, the semi-transparent structure refers to a material form with a light transmittance between transparent and opaque, which can be made of polycarbonate or acrylic materials. Its internal light scattering characteristics can transform the point light source 1211 into a surface light source 1211. The snap-fit ​​structure refers to a quick assembly method achieved by mechanical snap-fit ​​or sliding rail structure, such as using elastic claws and limiting grooves to achieve tool-free disassembly and assembly of the protective shell 33 and the first module 10. The warning light structure refers to an optical system that converts the direct light of the lighting device 121 into scattered light through the semi-transparent protective shell 33, for example, by using the frosted treatment or ribbed structure on the inner surface of the protective shell 33 to make the light diffuse evenly.

[0127] Specifically, when the lighting device 121 is activated, the light beam undergoes diffuse reflection through the inner surface of the translucent protective shell 33, and the originally concentrated light is dispersed to a wider angle range, forming a uniform halo around the emergency stick, which can enhance warning visibility in smoke or rain and fog environments; the snap-fit ​​structure between the protective shell 33 and the first module 10 achieves axial fixation through the cooperation of the limiting protrusion and the groove, ensuring that the protective shell 33 will not fall off when impacted; in the vertical placement state, the compass 34 on the top of the protective shell 33 automatically calibrates the orientation by gravity, providing directional reference for the user without manual adjustment.

[0128] Compared with existing technologies, the warning function of traditional emergency tools relies on independent LED light groups, which require separate circuits and lampshade structures. In contrast, this solution achieves the dual functions of protective structure and optical diffusion in the same space through the reuse design of semi-transparent protective shell 33 and lighting device 121.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
