[0002] As the proportion of the elderly population in my country increases, their numbers increase, and the problems brought about by an aging population become increasingly serious, increasing awareness of the issues facing the elderly population. Due to their aging bodies, the elderly are highly susceptible to falls, resulting in injuries and fractures, and are also prone to developing acute illnesses that can threaten their health. Therefore, research into protective equipment that reduces the harm caused by falls in the elderly is of great significance to elderly care. A fall in the elderly often occurs within 1 to 3 seconds. Falls severely impact the health of the elderly and can lead to serious complications such as cerebral hemorrhage and fractures. Therefore, fall protection belts for the elderly are now available on the market, protecting the hip, femur, and lower spine in the event of a fall.

[0003] Current protective belts generally have a gas generator and an airbag that can surround the elderly person's waist along their length. When an elderly person falls, the gas generator inflates the airbag from one end until the airbag is fully inflated. However, the inflation is uneven during use and the elderly person cannot be protected in time. Moreover, the airbag is used to cushion instantaneous impact injuries. After a fall, the continuously inflated airbag will support the elderly person's waist, and the waist will continue to be stressed, causing back pain. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Example 1

[0022] Reference Figure 1-3 This embodiment provides an intelligent anti-fall airbag belt, comprising a belt body 1, a sensing module 2 and an inflation module 3. The belt body 1 is provided with the sensing module 2 and the inflation module 3.

[0023] The sensing module 2 is used to monitor falls and send control instructions to the inflation module 3;

[0024] The inflation module 3 includes an air tank 31, a main pipe 32, an electric control valve 33, a conduit 34, an airbag 35 and a pressure relief valve 36. The air tank 31, the main pipe 32 and the airbag 35 are fixedly connected to the outside of the belt body 1. The air tank 31 is fixedly connected to the main pipe 32, and the main pipe 32 is connected to the airbag 35 through the conduit 34. The conduit 34 is provided with an electric control valve 33, which is used to receive the control instruction and open according to the control instruction. The airbags 35 are respectively provided with pressure relief valves 36.

[0025] In this embodiment, preferably, the sensing module 2 can monitor the elderly when they fall. When the elderly are detected to have fallen, a control instruction is sent to the electric control valve 33 on the inflation module 3. The electric control valve 33 receives the control instruction and opens according to the control instruction. At this time, the gas can pass through the conduit 34 and open the gas tank 31 at the same time. The gas in the gas tank 31 can enter the main pipe 32 and then enter the airbag 35 through the conduit 34. The airbag 35 expands to play a protective role. The pressure relief valve 36 can prevent the elderly from falling and pressing their body on the airbag 35 to make the internal pressure of the airbag 35 too high, thereby automatically discharging part of the gas to prevent the airbag from continuously inflating after the fall, which will prop up the elderly's waist and cause continuous stress on the waist, while the shoulders and buttocks are close to the ground, making the posture uncomfortable and causing low back pain.

[0026] Example 2

[0027] Reference Figure 1-4 , This embodiment is based on the previous embodiment, and differs from the previous embodiment in that.

[0028] There are more than one airbag 35 and they are evenly distributed on the outside of the belt body 1. Each airbag 35 is connected to the main pipe 32 via a conduit 34.

[0029] In this embodiment, it is preferred that multiple airbags 35 are provided. After the elderly person falls, the electric control valve 33 on the corresponding airbag 35 is opened, and the gas can pass through the conduit 34. At the same time, the gas storage tank 31 is opened, and the gas in the gas storage tank 31 can enter the main pipe 32, and then enter the corresponding airbag 35 through the conduit 34. The airbag 35 expands to play a protective role.

[0030] The airbag 35 is made of non-elastic material.

[0031] In this embodiment, it is preferred to avoid that when the airbag 35 is squeezed, the surface of the airbag 35 expands, thereby affecting the protective effect.

[0032] The sensing module 2 includes a six-axis gyroscope 21, a judgment unit 22 and an instruction sending unit 23. The six-axis gyroscope 21 monitors the acceleration information and the inclination information of the human body relative to the ground, and inputs the acceleration information and the inclination information into the judgment unit 22. The judgment unit 22 is used to determine whether a fall occurs. If a fall occurs, the instruction sending unit 23 is activated, and the instruction sending unit 23 sends a control instruction to the electric control valve 33.

[0033] In this embodiment, the judgment unit 22 preferably adopts an existing controller, and a preset acceleration threshold and inclination threshold are set inside the controller. If the acceleration information and the inclination information are both greater than the preset acceleration threshold and inclination threshold, indicating that a fall has occurred, the instruction sending unit 23 is activated, and the instruction sending unit 23 sends a control instruction to the electric control valve 33. The instruction sending unit 23 is an existing instruction transmitter.

[0034] In one embodiment, after being activated, the instruction sending unit 23 sends control instructions to the electric control valve 33 and the gas storage tank 31 at the same time. After receiving the control instructions, the gas storage tank 31 opens and releases gas.

[0035] The pressure relief valve 36 includes a fixed cylinder 361 and a movable plate 362 . The fixed cylinder 361 is fixedly connected to the airbag 35 and has a through hole 3611 . The inner wall of the fixed cylinder 361 is slidably connected to the movable plate 362 .

[0036] Preferably in this embodiment, the movable plate 362 can slide on the inner wall of the fixed tube 361. When the movable plate 362 moves to above the through hole 3611, the gas inside the airbag 35 can be released from the through hole 3611 to prevent the continuously inflated airbag from supporting the elderly's waist after a fall, causing continuous stress on the waist and causing back pain.

[0037] The inner wall of the fixed cylinder 361 is fixedly connected to the fixed ring 3612 . The fixed ring 3612 is fixedly connected to one end of the spring 363 . The other end of the spring 363 is fixedly connected to the movable plate 362 .

[0038] In this embodiment, the movable plate 362 is preferably positioned below the through hole 3611 under the action of the elastic force of the spring 363. When an elderly person falls, their body presses against the airbag 35, causing excessive pressure inside the airbag 35. This pressure pushes the movable plate 362 upward, compressing the spring 363, causing the movable plate 362 to move above the through hole 3611, thereby automatically discharging some of the gas inside the airbag 35. This prevents the airbag, which continues to be inflated after a fall, from supporting the elderly person's waist, causing continuous pressure on the waist and causing back pain.

[0039] The movable plate 362 is fixedly connected to the movable tube 364 . The outer wall of the movable tube 364 is slidably connected to the inner side of the fixed ring 3612 . The spring 363 is sleeved on the movable tube 364 .

[0040] In this embodiment, preferably, when the movable plate 362 moves, it drives the movable tube 364 to slide inside the fixed ring 3612 , thereby improving the stability of the movable plate 362 when moving.

[0041] The inner end wall of the fixed cylinder 361 is fixedly connected to the accommodating capsule 365 , and the accommodating capsule 365 is filled with a non-Newtonian fluid 366 .

[0042] In the preferred embodiment of the present invention, after the elderly person falls, the airbag 35 first hits the ground, and the airbag 35 acts as a buffer. At this time, the airbag 35 is instantly squeezed by the impact force, and the air pressure inside the airbag 35 instantly increases, and the instantaneous triggering pushes the movable plate 362 to push the movable tube 364 to hit the accommodating bag 365. The non-Newtonian fluid 366 inside the accommodating bag 365 is hit and maintains its original shape, supporting the movable tube 364, so that the movable plate 362 cannot move to the top of the through hole 3611, thereby preventing the gas inside the airbag 35 from being discharged and affecting the protective effect.

[0043] When the elderly person falls to the ground completely, the elderly person's body presses on the airbag 35, and the pressure inside the airbag 35 is too high. The air pressure pushes the movable plate 362 to move upward, compressing the spring 363. The movable tube 364 slowly applies pressure to the non-Newtonian fluid 366 inside the accommodating bag 365. The non-Newtonian fluid 366 cannot support the movable tube 364, and the accommodating bag 365 is squeezed and deformed. The movable plate 362 moves to the top of the through hole 3611, thereby automatically discharging part of the gas inside the airbag 35, preventing the airbag from continuously inflating after a fall, which will prop up the elderly person's waist. The waist is continuously under pressure, while the shoulders and buttocks are close to the ground, making the posture uncomfortable and causing back pain.
