Description

Technical Field

[0001] This invention relates to a belt, specifically a modular multifunctional emergency safety belt, belonging to the field of emergency safety equipment technology. Background Technology

[0002] With the increase in daily travel, water-based operations, and outdoor adventures, the probability of sudden safety accidents such as falling into water has also increased. In such accidents, obtaining buoyancy support in the first instance is crucial to ensuring the safety of people's lives. Therefore, portable and efficient emergency rescue equipment has become an important research and development direction in the field of emergency safety. Belts, as essential items worn daily, are convenient to wear, fit the body closely, and are not easy to fall off, making them an ideal carrier for integrating emergency rescue functions. However, ordinary belts in existing technology only have basic functions such as waist tightening and decoration, without any emergency safety protection structure, and cannot play a role in dangerous scenarios such as sudden falling into water. Conventional rescue equipment, such as life rings and life jackets, are bulky and inconvenient to carry around daily, and can only be prepared in advance for specific water scenarios. Small inflatable rescue equipment such as life bracelets have limited airbag capacity and insufficient buoyancy support. Moreover, most of them require manual inflation, which is difficult to complete quickly in the panic and loss of limb control after falling into the water, and can easily delay the best rescue opportunity. Summary of the Invention

[0003] The purpose of this invention is to provide a modular, multifunctional emergency safety belt. This invention integrates a rescue airbag module into a belt worn daily. Through a modular air supply mechanism that is automatically triggered upon contact with water, it can quickly form a surrounding buoyancy support without human intervention when the person falls into water, thereby significantly improving the success rate of self-rescue and emergency safety in water-related emergencies.

[0004] The technical solution of the present invention is as follows: A modular multifunctional emergency safety belt includes a belt body, with male and female buckles connected to both ends of the belt body, which cooperate with each other; the belt body has a receiving cavity extending along its length, and an inflatable foldable airbag is provided in the receiving cavity; the belt body is provided with an air supply interface for communicating with the foldable airbag; an air supply unit containing a high-pressure air source is detachably connected to the belt body, and the air supply unit has a connection end that mates with the air supply interface; the air supply unit integrates a triggering mechanism, which is configured to conduct the air supply channel from its internal high-pressure air source to the connection end when the air supply unit is immersed in water.

[0005] The aforementioned modular multi-functional emergency safety belt has an air outlet valve core at the air outlet end of the air supply unit, which is located above the connection end.

[0006] The aforementioned modular multi-functional emergency safety belt includes a triggering mechanism comprising a cavity disposed between the exhaust valve core and the connecting end, the front side of which is connected to the outside; a rebound plate located below the exhaust valve core is provided inside the cavity, the rebound plate is provided with multiple first springs, the other end of which is connected to the upper wall of the cavity; a pin is provided on the rebound plate, the pin corresponding to the exhaust valve core; and a release mechanism for limiting the rise of the rebound plate is provided at the front end of the cavity.

[0007] The aforementioned modular multi-functional emergency safety belt includes a release mechanism comprising a water-soluble block at the front end of the cavity, a movable block at the rear end of the water-soluble block, a convex plate on the movable block, a second spring horizontally placed on the convex plate, and the other end of the second spring connected to the inner wall of the cavity; the lower end of the movable block is provided with a groove, which abuts against the upper part of the rebound plate.

[0008] The aforementioned modular multi-functional emergency safety belt has multiple ventilation holes on its rebound plate.

[0009] The aforementioned modular multi-functional emergency safety belt has a storage box at the front end with a female buckle, and a lid is rotatably connected to the top of the storage box.

[0010] The aforementioned modular multi-functional emergency safety belt has multiple vertical strips at the rear end of the air supply unit, and hooks at the lower ends of the vertical strips.

[0011] The aforementioned modular multi-functional emergency safety belt has its upper wall openings of the receiving cavity connected by Velcro.

[0012] The aforementioned modular multi-functional emergency safety belt has a connecting protrusion on one end of the belt body near the buckle; the air supply interface is located on the connecting protrusion.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, by setting a receiving cavity inside the belt body and arranging multiple folded airbags within the receiving cavity, the belt, which originally only had a waist-cinching function, is given an emergency life-saving function, achieving functional expansion without affecting daily wearing comfort. Simultaneously, by concealing the folded airbags within the receiving cavity, the overall structure is compact and aesthetically pleasing, avoiding the inconvenience of exposed structures. Furthermore, by setting a matching structure between the air supply interface and the connection end, the air supply unit can achieve modular and rapid connection and disassembly, facilitating replacement and maintenance, and improving the flexibility and reusability of the device. Simultaneous air supply from the air supply unit to multiple folded airbags allows for rapid inflation to generate sufficient buoyancy in a short time, significantly improving self-rescue capabilities in the event of falling into water. In particular, the inclusion of a triggering mechanism allows the device to automatically trigger the inflation process upon contact with water, eliminating the need for manual operation and effectively avoiding the problem of panic and inability to manually trigger the device in an emergency, thereby greatly improving emergency response speed and safety reliability.

[0014] 2. This invention establishes a stable and reliable gas control and triggering structure by setting an outlet valve core at the outlet end of the gas supply unit, combined with a rebound plate, a ejector pin, and a first spring located below it. This structure effectively seals the gas in the non-triggered state, preventing accidental leakage and improving the safety and airtightness of the device. Simultaneously, by setting a cavity between the outlet valve core and the connecting end, and connecting the front of the cavity to the outside, a channel is provided for external water to enter, thus providing conditions for automatic triggering. Furthermore, by setting a release mechanism composed of a water-soluble block, a moving block, a convex plate, and a second spring, in a dry environment, the water-soluble block limits the moving block, causing it to press the rebound plate through a groove, preventing it from moving upwards, thereby ensuring that the ejector pin will not open the outlet valve core, achieving stable locking. When the device encounters water, the water-soluble block dissolves and becomes ineffective, the moving block moves under the action of the second spring, releasing the restriction on the rebound plate. The rebound plate then rapidly moves upwards under the elastic force of the first spring, driving the ejector pin to open the outlet valve core, achieving rapid gas release and completing the automatic inflation process. This structure combines the principles of water-soluble triggering and elastic reset, resulting in sensitive triggering, rapid response, and a simple and reliable structure. Furthermore, by incorporating multiple vents on the rebound plate, gas can pass more smoothly through the rebound plate area during release, reducing airflow resistance, improving inflation efficiency, and ensuring that multiple folded airbags can fully deploy in a short time, thereby further enhancing buoyancy formation speed and stability.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example: A modular multi-functional emergency safety belt, as shown in Figures 1-5, includes a belt body 1. The belt body 1 preferably employs a composite structure of a closed-cell EVA foam core layer, high-strength nylon webbing, and a flexible TPU outer layer. The EVA core layer is fully laid along the length to provide basic buoyancy, while the outer layer is waterproof and anti-aging treated, possessing good wear resistance, tensile strength, and flexibility, suitable for daily wear and use in complex environments. The two ends of the belt body 1 are respectively connected to a male buckle 2 and a female buckle 3. The male buckle 2 and female buckle 3 cooperate with each other, preferably using a metal and engineering plastic composite structure, ensuring connection strength while reducing overall weight, facilitating quick donning and undoing. As shown in Figure 5, the belt body 1 has an internal receiving cavity 4 extending along its length. The inner wall of the receiving cavity 4 is preferably treated with a waterproof coating to prevent moisture intrusion from affecting the internal structure. The upper part of the receiving cavity 4 is connected to the outside, and the two walls are detachably connected by Velcro, allowing the receiving cavity 4 to be quickly opened and closed, facilitating the installation, replacement, and maintenance of the internal structure. The receiving cavity 4 contains an inflatable, deployable foldable airbag 5. The foldable airbag 5 is preferably made of TPU airtight material, possessing excellent airtightness and pressure resistance. In its folded state, it fits snugly within the receiving cavity 4, ensuring the overall compactness of the belt body 1 and not affecting daily wear comfort. The inner wall of the receiving cavity 4 has a waterproof coating, and the EVA foam core layer is integrated with the receiving cavity 4. When folded, the foldable airbag 5 fits snugly against the core layer, not affecting daily wear, as shown in Figure 2. The belt body 1 has a connecting protrusion 6 near the buckle 3. The connecting protrusion 6 is integrally formed or fixed to the belt body 1 by a hot-pressing process. The connecting protrusion 6 has an air supply interface 7 for communication with the foldable airbag 5. The air supply interface 7 is preferably made of pressure-resistant plastic or metal material and is connected to the foldable airbag 5 via a pressure-resistant hose to achieve stable gas delivery. As shown in Figure 3, the belt body 1 is detachably connected to an air supply unit 8 containing a high-pressure air source. The air supply unit 8 is preferably made of aluminum alloy or high-strength steel, which has good pressure resistance and lightweight characteristics. The air supply unit 8 is provided with a connection end 9 that mates with the air supply interface 7. The connection end 9 and the air supply interface 7 preferably adopt a plug-in sealed connection structure, and an aging-resistant rubber sealing ring is provided at the connection to ensure airtightness after connection, realizing modular quick connection and disassembly of the air supply unit 8 and the belt body 1. The rear end of the air supply unit 8 is provided with multiple vertical bars 25, which are preferably made of metal or high-strength plastic. The lower end of each bar has an integrally formed hook block 26, which is adapted to the corresponding snap-fit ​​structure on the belt body 1. After snap-fit ​​engagement, the air supply unit 8 can be stably fixed to prevent it from shaking or falling off during daily wear or emergency situations.The front end of the unit with the female buckle 3 is integrally formed with a storage box 23 having a waterproof and sealed structure. The storage box 23 is preferably made of lightweight engineering plastic. A box cover 24 is rotatably connected to the top of the storage box 23 via a pivot. A snap-fit ​​closure structure can be provided between the box cover 24 and the storage box 23. The storage box 23 has an inner compartment for storing small emergency items, further enhancing the product's multifunctionality and practicality. As shown in Figure 4, the air outlet end of the air chamber of the air supply unit 8 is equipped with an air outlet valve core 11. The air outlet valve core 11 is located above the connecting end 9. The air outlet valve core 11 is preferably made of corrosion-resistant metal material and achieves high-pressure gas sealing and opening control through precise fit, ensuring the airtightness of the air supply unit 8 in the non-triggered state. The air supply unit 8 is equipped with a manual hidden button. Pressing it will directly open the air outlet valve core 11 to conduct the air source. The air supply unit 8 integrates a triggering mechanism 10, which is configured to connect the internal high-pressure air source to the air supply channel of the connecting end 9 when the air supply unit 8 is immersed in water. The triggering mechanism 10 includes a cavity 12 disposed between the air outlet valve core 11 and the connecting end 9. The front side of the cavity 12 is connected to the outside, providing a channel for external water to enter and realizing the structural conditions for water immersion triggering. The cavity 12 is provided with a rebound plate 13 located below the air outlet valve core 11. The rebound plate 13 is preferably made of lightweight high-strength engineering plastic, and multiple first springs 14 are evenly arranged on it. The first springs 14 are preferably made of 304 stainless steel, which has good elastic recovery performance and corrosion resistance. One end of the first spring 14 is fixedly connected to the rebound plate 13, and the other end is fixedly connected to the upper wall of the cavity 12. A push pin 15 is integrally formed on the spring plate 13 at the position corresponding to the air outlet valve core 11. The push pin 15 is coaxial with the air outlet valve core 11 and is used to push open the air outlet valve core 11 when the spring plate 13 moves upward, so as to realize the conduction of the high pressure gas source. The spring plate 13 is also provided with a plurality of evenly distributed vent holes 22. The vent holes 22 are set through the spring plate 13 to reduce the airflow resistance during the gas release process, so that the high pressure gas can quickly pass through the area of ​​the spring plate 13 to the connecting end 9, thereby improving the inflation efficiency.The front end of the cavity 12 is provided with a release mechanism 16 for limiting the rise of the rebound plate 13. The release mechanism 16 includes a water-soluble block 17 disposed at the front end of the cavity 12. The water-soluble block 17 is preferably made of water-soluble PVA material that can be completely dissolved within 3-5 seconds after falling into water, so as to achieve sensitivity and timeliness of triggering. The rear end of the water-soluble block 17 abuts against a moving block 18. The moving block 18 is preferably made of wear-resistant engineering plastic, and a protruding plate 19 is integrally formed on it. A second spring 20 is horizontally placed on the protruding plate 19. One end of the second spring 20 is fixedly connected to the protruding plate 19, and the other end is fixedly connected to the inner wall of the cavity 12, so as to provide the resetting and moving power for the moving block 18. The lower end of the moving block 18 is provided with a groove 21. The groove 21 is adapted to the upper edge of the rebound plate 13, and the groove 21 abuts against the top of the rebound plate 13, thereby limiting the rebound plate 13 in a dry and non-triggered state and preventing it from moving upward under the elastic force of the first spring 14. In a dry environment, the water-soluble block 17 provides lateral restraint to the moving block 18, allowing the moving block 18 to stably press the rebound plate 13 through the groove 21. The ejector pin 15 maintains a distance from the air outlet valve core 11 and will not push open the air outlet valve core 11, keeping the high-pressure air source of the air supply unit 8 in a sealed state. When the air supply unit 8 is immersed in water, the water enters through the connecting port on the front side of the cavity 12 and comes into contact with the water-soluble block 17. The water-soluble block 17 quickly dissolves and loses its restraining effect on the moving block 18. Under the elastic restoring force of the second spring 20, the moving block 18 moves laterally along the cavity 12, and the groove 21 separates from the rebound plate 13, releasing the pressure restraint on the rebound plate 13. Subsequently, the rebound plate 13 quickly bounces upward under the elastic force of the first spring 14, causing the ejector pin 15 to quickly push open the air outlet valve core 11, connecting the high-pressure air source inside the air supply unit 8 to the air supply channel of the connecting end 9, realizing the rapid release of high-pressure gas and completing the automatic triggering action of immersion. The buckle 3 integrates a concealed hard alloy window breaker and an anti-accidental rope-cutting blade, allowing for quick opening in emergencies. The belt body 1 is equipped with an intelligent monitoring module, a waterproof and detachable structure electrically connected to the belt body 1 via a standardized intelligent module interface. The module incorporates a microprocessor, a water-sensing sensor, a heart rate monitoring sensor, a Bluetooth communication module, and a micro-rechargeable battery. It enables real-time monitoring of human vital signs, data transmission to a mobile terminal via Bluetooth, and intelligent sensing of water ingress, triggering the mechanism 10 for automatic inflation, compatible with advanced intelligent models. The air supply unit 8 has a threaded hole at its rear; the belt body 1 has a knob corresponding to the threaded hole, with a threaded post at its front. After connecting the air supply unit 8 to the belt body 1, rotating the knob engages the threaded post in the threaded hole, further strengthening the connection and preventing separation due to the instantaneous large reaction force and impact during inflation.

[0019] Working principle: During daily wear, the air supply unit 8 is connected to the air supply interface 7 on the connecting protrusion 6 of the belt body 1 via the connecting end 9 to achieve a plug-in sealed connection. The hook block 26 at the rear end of the air supply unit 8 is engaged with the corresponding snap-fit ​​structure of the belt body 1, thus completing the double fixation of the air supply unit 8 and preventing it from shaking or falling off during daily wear. At this time, the folded airbag 5 is folded and stored in the receiving cavity 4 of the belt body 1. The trigger mechanism 10 is in the locked state. Under the limitation of the water-soluble block 17, the moving block 18 presses the rebound plate 13 through the groove 21. The first spring 14 is in a compressed state. The pin 15 and the air valve core 11 maintain a distance. The high-pressure air source inside the air supply unit 8 is sealed. The whole device maintains a compact daily wear form and does not affect normal use.

[0020] When a user accidentally falls into water, after the air supply unit 8 comes into contact with the water, the water enters the trigger mechanism 10 through the connecting port on the front side of the cavity 12 and quickly comes into contact with the water-soluble block 17. The water-soluble block 17 dissolves in the water and loses its limiting function. At this time, the moving block 18 moves laterally along the cavity 12 under the elastic restoring force of the second spring 20, and its lower end groove 21 separates from the rebound plate 13, releasing the pressure restriction on the rebound plate 13.

[0021] The rebound plate 13 quickly bounces upward under the elastic force of the first spring 14, which drives the ejector pin 15 on it to quickly open the air valve core 11, and conducts the high-pressure air source inside the air supply unit 8 to the air supply channel of the connection end 9. The high-pressure gas is released quickly and is delivered to the folding airbag 5 through the connection end 9, the air supply interface 7 and the pressure-resistant hose in sequence.

[0022] After receiving high-pressure gas, the folding airbag 5 quickly inflates and unfolds, breaking through the Velcro connection of the receiving cavity 4 to the upper wall. Because of its split inflatable structure, it can effectively avoid the restriction of the waistband loop of pants and fully unfold to form a surrounding buoyancy structure, providing reliable buoyancy support for users who fall into the water. No manual operation is required throughout the process, and it can automatically and quickly inflate after immersion in water, greatly improving the efficiency and safety of self-rescue in water-related emergencies.
