Description

Technical Field

[0001] The present invention relates to the technical field of lifesaving equipment, and in particular to an anti-drowning lifesaving bracelet that can sense abnormal heart rate and automatically inflate. Background Art

[0002] At present, the mortality rate of drowning in swimming among children and adolescents is very high. The suddenness and unpredictability of the drowning have obvious limitations on traditional protective measures. Most swimmers will not actively wear swimming suits or swimming rings outdoors for portability reasons. Therefore, life-saving bracelets were born. By setting up air tanks and air bags inside the life-saving bracelets, when the user is detected drowning, the air bags are actively inflated and popped out of the bracelet, thereby generating buoyancy to float the user, significantly improving the safety of outdoor swimmers.

[0003] In the aforementioned prior art, the airbag is usually installed inside the life-saving bracelet. In order to minimize the volume and improve portability, the airbag is usually set under the bracelet cover and closely arranged with various components inside the bracelet. Before the airbag pops out, the cover needs to be actively opened and then the airbag is popped out; if the user sinks into a deep water area, the water pressure is relatively high at this time, and the overall area occupied by the bracelet cover is relatively large, so the force required to open the cover may be insufficient, resulting in a slow response speed of the cover and a reduction in the user's floating speed; if the initial driving force of the cover is increased, although the opening speed can be increased, the water pressure is relatively low in shallow water areas, and the cover opening forcefully and the rapid popping out of the airbag will cause the bracelet to vibrate strongly, which may easily damage the internal components of the bracelet and even affect the inflation of the airbag; therefore, the currently existing life-saving bracelets cannot take into account both the stability and speed of the airbag popping out. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-drowning life-saving bracelet that senses abnormal heart rate and automatically inflates, so as to solve the problem in the prior art that if a user sinks into a deep water area, the water pressure is relatively high.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] See also Figures 1 to 11The present invention provides an anti-drowning lifesaving bracelet that senses abnormal heart rate and automatically inflates, comprising a bracelet housing 1, an operation panel 2, a central control chip 3, an air chamber 4, an air bag 5 and a pop-up assembly, wherein the pop-up assembly comprises a pop-up plate 6, multiple pop-up springs 7, multiple rollers 8, a mini abutment plate 9 and two torsion springs 10. The bracelet housing 1 is ring-shaped and has a wearing groove 11 and a storage compartment 12. The pop-up assembly further comprises a battery pack 13 and a sealing gasket 14. The bracelet housing 1 has a charging port 15. The pop-up assembly further comprises an inflation valve 16 and a pressure sensor 17. The pop-up assembly further comprises two limit units, two pop-up reinforcement units and two inflation units. The limit unit comprises a metal limit bevel 18, a strong electromagnet 19 and a limit spring 20. The mini supporting plate 9 has a limiting groove 21, the storage bin 12 has a groove 22, the pop-up reinforcement unit includes a winding component 23, a winding shaft 24 and a reinforcement connecting rope 25, the inflation unit includes a high-pressure air pump 26, a fixed pipe 27, a telescopic hose 28 and multiple small sealing rings 29, the pop-up assembly also includes a wristband mounting unit, the wristband mounting unit includes two wrist side contact pads 30, two wrist upper and lower contact pads 31 and two mounting adjustment mechanisms, the wristband mounting unit also includes two swimming posture detection sensors 32, two heart rate detection sensors 33 and two large sealing rings 34, the mounting adjustment mechanism includes an adjustment slider 35, a threaded rod 36, a rotating slide shaft 37 and a turning handle 38, and the adjustment slider 35 has multiple threaded holes 39.

[0034] Among them, the operation panel 2 is arranged on the outer wall of the wristband shell 1, the central control chip 3 is arranged on the inner wall of the wristband shell 1, the air chamber 4 and the airbag 5 are both arranged inside the wristband shell 1, the wristband shell 1 is ring-shaped, and the wristband shell 1 has a wearing groove 11 and a storage chamber 12. The airbag 5 is placed inside the storage chamber 12, and the two ends of the multiple pop-up springs 7 are respectively movably connected to the inner wall of the storage chamber 12 and the pop-up plate 6, and the multiple rollers 8 are sequentially arranged on the inner side wall of the storage chamber 12, and the two ends of the mini support plate 9 are rotatably connected to the storage chamber 12. The pop-up plate 6 and the airbag 5 support each other, and the two ends of the mini support plate 9 are respectively provided with corresponding torsion springs 10. When the airbag 5 is ejected, the roller 8 can reduce the resistance of the ejection, increase the ejection speed, and avoid the friction between the airbag 5 and the inner wall of the storage bin 12, thereby increasing the service life of the airbag 5; during normal swimming, the time and the swimmer's heart rate can be viewed through the operation panel 2, so that the user can understand his or her swimming situation; when it is detected that the user's heart rate drops to a preset value and the swimming posture is in a free fall state, the central control chip 3 releases the limit on the mini abutment plate 9, and the two torsion springs 10 drive the mini abutment plate 9 to rotate and open, and the ejection The spring 7 drives the pop-up plate 6 to move, popping out the airbag 5 in the storage compartment 12, and then the air compartment 4 starts to inflate the airbag 5 to make the user float up; the airbag 5 of the present application can provide 200N of buoyancy after being filled with air, which can meet the buoyancy requirements of a 70KG adult; at the same time, relying on the ring shape of the bracelet shell 1, it can ensure that the internal space is utilized to the maximum extent while being small in size, so that the airbag 5, the air compartment 4 and the battery pack 13 inside the present application are greatly increased in size compared to traditional wristband bracelets, significantly increasing buoyancy and battery life.

[0035] Secondly, the wristband housing 1 has a charging port 15. The battery pack 13 is disposed inside the wristband housing 1 and is located on one side of the storage compartment 12. The sealing gasket 14 is disposed on the outside of the wristband housing 1 and is adapted to fit the charging port 15. The battery pack 13 is used to improve the battery life of the entire wristband, the charging port 15 is used for charging, and the sealing gasket 14 is used to protect the charging port 15.

[0036] At the same time, the inflation valve 16 passes through the wristband housing 1 and is arranged on the air chamber 4, and the pressure sensor 17 is arranged inside the air chamber 4. The inflation valve 16 is used to replenish the air in the air chamber 4, and the pressure sensor 17 is used to detect the air pressure inside the air chamber 4.

[0037] In addition, two limiting units are symmetrically arranged inside the storage compartment 12, and two pop-up reinforcement units and two inflation units are symmetrically arranged inside the bracelet housing 1 and are all connected to the airbag 5. The limiting units limit the position of the mini-holding plate 9, and the pop-up reinforcement units reinforce the pop-up of the airbag 5 to improve stability; the inflation units are used to inflate the airbag 5.

[0038] Then, the mini supporting plate 9 has a limiting groove 21, the storage bin 12 has a groove 22, the metal limiting bevel 18 is slidably connected to the groove 22, one end of the metal limiting bevel 18 is adapted to the limiting groove 21, and the two ends of the limiting spring 20 are respectively movably connected to the metal limiting bevel 18 and the inner wall of the groove 22, and the strong electromagnet 19 is arranged inside the groove 22. When the mini supporting plate 9 is closed, it first contacts the inclined surface of the metal limiting bevel 18, causing it to rebound, and then snaps into the limiting groove 21 to complete the limiting of the mini supporting plate 9. When the mini supporting plate 9 needs to be released from the limiting, the powerful electromagnet 19 is energized to generate magnetic force, driving the metal limiting bevel 18 to retract and disengage from the limiting groove 21. At this time, under the action of the torsion spring 10, the mini supporting plate 9 rotates to open, and at the same time, the pop-up plate 6 drives the airbag 5 to pop out. Relying on the action of the airbag 5, the mini supporting plate 9 can also be pushed to open quickly, significantly improving the pop-up speed.

[0039] Again, the reeling component 23 is disposed inside the bracelet housing 1, and the output end of the reeling component 23 is fixedly connected to the reeling shaft 24. One end of the reinforcement connecting rope 25 is wound around the reeling shaft 24, and the other end of the reinforcement connecting rope 25 passes through the storage bin 12 and is fixedly connected to the airbag 5. The reeling component 23 is a driving motor. When the reeling component 23 is started, it drives the reeling shaft 24 to rotate, thereby reeling the reinforcement connecting rope 25 so that the airbag 5 can be stored in the storage bin 12 after being deflated. When the airbag 5 is pushed out, the reinforcement connecting rope 25 is driven to unwind and extend along with the airbag 5, thereby reinforcing the airbag 5 and preventing the telescopic hose 28 from breaking or falling off due to insufficient support.

[0040] In addition, the high-pressure air pump 26 is arranged inside the air chamber 4, and the fixed pipe 27 is fixedly connected to the inside of the wristband housing 1. The two ends of the fixed pipe 27 are respectively connected to the high-pressure air pump 26 and one end of the telescopic hose 28. The other end of the telescopic hose 28 passes through the wristband housing 1 and is connected to the airbag 5. The small sealing ring 29 is provided at the penetration point of the reinforced connecting rope 25 and the telescopic hose 28. When inflation is required, the central control chip 3 controls the start of the high-pressure air pump 26 to pump gas from the air chamber 4, into the fixed pipe 27, through the telescopic hose 28 to the airbag 5, and the small sealing ring 29 seals the sliding and telescopic point of the telescopic hose 28 and the reinforced connecting rope 25 to prevent water from entering the interior of the wristband housing 1.

[0041] Thus, the wristband mounting unit is provided on the wristband housing 1; the two wrist side contact pads 30 and the two wrist upper and lower contact pads 31 are sequentially provided inside the wearing slot 11; the two mounting adjustment mechanisms are symmetrically provided inside the wristband housing 1; and the two wrist upper and lower contact pads 31 are respectively fixedly connected to the corresponding mounting adjustment mechanisms. When wearing the wristband, the user passes the hand through the wearing slot 11, with the wrist positioned therein. At this time, the wrist side contact pads 30 provide contact support to the side of the wrist, improving comfort, while the wrist upper and lower contact pads 31 provide contact to the upper and lower parts of the wrist, improving comfort; at the same time, the mounting adjustment mechanism can drive the wrist upper and lower contact pads 31 to move, clamping the wrist and improving wearing security.

[0042] Furthermore, the two swimming posture detection sensors 32 are respectively arranged inside the corresponding wrist side contact pads 30, and the two heart rate detection sensors 33 are respectively arranged on the corresponding wrist upper and lower contact pads 31, and the two large sealing rings 34 are fixedly connected to the inner wall of the wearing groove 11, and are symmetrically distributed on both sides of the wrist side contact pads 30 and the wrist upper and lower contact pads 31. The swimming posture detection sensor 32 can detect the user's current swimming posture. The heart rate detection sensor 33 is used to detect the user's heart rate and set a preset heart rate value. When the heart rate drops below the preset value, it indicates that the user is at risk of drowning. When it is detected that the user is in free fall and the heart rate also drops to the preset value, it indicates that the user is drowning. The mini support plate 9 can be released, and then the airbag 5 is popped out and inflated to make the user float. At the same time, the operation panel 2 is equipped with an audible and visual alarm, which is activated at this time to alert surrounding personnel for rescue. The central control chip 3 also has an Internet connection function and is connected to the server background. When a drowning situation is triggered, the upper system automatically alarms and sends the drowning location to ensure user safety to the greatest extent. Among them, the model of the heart rate detection sensor 33 is: GH3011 / GH3018; the model of the swimming posture detection sensor 32 is: BMA456; the large sealing ring 34 can seal the sliding part of the adjustment slider 35 to prevent water from entering the inside of the wristband housing 1.

[0043] Finally, the adjustment slider 35 is slidably connected to the bracelet housing 1. One end of the adjustment slider 35 is fixedly connected to the upper and lower wrist contact pads 31. The threaded rod 36 and the threaded hole 39 are adapted to each other. One end of the rotating slide 37 is fixedly connected to the turning handle 38. The other end of the rotating slide 37 passes through the bracelet housing 1 and is fixedly connected to the threaded rod 36. The small sealing ring 29 is provided at the connection between the rotating slide 37 and the bracelet housing 1. When the bracelet housing 1 needs to be fixed to the wrist, the adjustment slider 35 is first moved to the wrist to fit it. Then, the turning handle 38 is held and moved toward the inside of the bracelet housing 1. The threaded rod 36 is inserted and close to the threaded hole 39. At this time, the turning handle 38 is rotated. Through the connection of the rotating slide 37, the threaded rod 36 is driven to screw into the threaded hole 39, completing the limiting of the adjustment slider 35, thereby completing the installation and fixation of the bracelet housing 1.

[0044] When using the anti-drowning life-saving bracelet of the present embodiment that senses abnormal heart rate and automatically inflates, during normal swimming, the time and the swimmer's heart rate can be viewed through the operation panel 2, so that the user can understand his or her swimming situation; when it is detected that the user's heart rate drops to a preset value and the swimming posture is in a free fall state, the strong electromagnet 19 is energized to generate magnetic force, driving the metal limiting bevel 18 to retract and disengage from the limiting groove 21. At this time, under the action of the torsion spring 10, the mini holding plate 9 rotates to open, and at the same time, the pop-up plate 6 drives the airbag 5 to pop out. The function of the airbag 5 can also push the mini holding plate 9 to open quickly, significantly increasing the ejection speed. Then the central control chip 3 controls the high-pressure air pump 26 to start, extracting gas from the air chamber 4, entering the fixed pipe 27, and passing through the telescopic hose 28 to reach the airbag 5 to inflate, so that the user floats up. In addition, after use, the valve of the airbag 5 is opened to discharge the internal gas, and then the reeling component 23 is started, driving the reeling shaft 24 to rotate, thereby reeling the reinforcement connecting rope 25, so that the airbag 5 can be stored in the storage compartment 12 after being deflated.

[0045] Through the above-mentioned structural setting, the resistance of the water flow can be reduced by the mini holding plate 9. At the same time, the cooperation of the torsion spring 10 and the pop-up spring 7 can accelerate the opening of the mini holding plate 9 and increase the pop-up speed of the airbag 5. In addition, relying on the separately arranged storage compartment 12, the airbag 5 is separated from the components inside the bracelet housing 1, avoiding damage to the bracelet as a whole and internal components during rapid pop-up, thereby improving the service life and stability of the bracelet while ensuring the pop-up speed.

[0046] The above disclosure is merely one or more preferred embodiments of the present application and is not intended to limit the scope of the present application. A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
