[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] This embodiment provides an automatic protection airbag belt mechanism for preventing the elderly from falling, including a belt 10, as Figure 1 shown

[0029] When the above-mentioned belt 10 is in a circular shape, foldable airbags 1 are provided at both sides, the airbags 1 on both sides are communicated, and a fixing plate 12 is provided in the middle of the airbags on both sides;

[0030] Male buckle 9-1 and female buckle 9-2 which cooperate with each other are respectively provided at both ends of the belt 10. A power supply charging socket is provided in the male buckle 9-1, and a power-on safety switch 6 is provided in the female buckle 9-2. The power supply is turned on by the cooperation of the male buckle and the female buckle;

[0031] The above-mentioned fixing plate 12 is provided with a gas cylinder 2, a gas cylinder opening fixator 3, a telescopic electromagnetic clutch 4, an on-off switch 5, a power supply 7, and a 9-axis inclination sensor 8;

[0032] The structure of the telescopic electromagnetic clutch 4 includes a "T"-shaped movable center 4-1, a housing 4-2, a sealing thread 4-3, a power cord 4-4, a sealing plug 4-5, a sealing thread 4-6, a spring 4-7, a circlip 4-8, and a coil 4-9; the housing 4-2 is cylindrical, and a small cylinder is integrally connected inward at one end of the cylindrical housing 4-2. A coil 4-9 is provided between the outer wall of the small cylinder and the inner wall of the housing 4-2. A power cord 4-4 is connected to the coil 4-9. A circlip 4-8 for pressing against the coil 4-9 is provided on the circumferential outer wall of the small cylinder. A movable center 4-1 is provided in the small cylinder. A spring 4-7 is provided between the extending end of the movable center 4-1 and the coil 4-9; the movable center 4-1 and the gas cylinder 2 are arranged on the same axis, as Figure 2 andFigure 4 as shown;

[0033] The structure of the cylinder opening fixator 3 described above is a stepped ring shape, and a balloon inflation port 15 is radially arranged in the middle of the stepped ring. As Figure 3 shown, the telescopic electromagnetic clutch 4 and the gas cylinder 2 are respectively connected to both ends of the cylinder opening fixator 3 of the stepped ring shape. The moving center point 4-1 displaces and contacts the nozzle of the gas cylinder 2, and breaks through the nozzle of the gas cylinder. The gas cylinder 2 releases gas and fills the safety balloon 1 through the balloon inflation port 15;

[0034] Under normal circumstances, the moving center point 4-1 and the gas cylinder 2 are arranged on the same axis and do not contact the nozzle of the gas cylinder 2. When the elderly person falls, the 9-axis inclination sensor 8 transmits a signal to the telescopic electromagnetic clutch 4. When the moving center point 4-1 of the telescopic electromagnetic clutch 4 moves rapidly, in the case of triggering and breaking through the nozzle of the gas cylinder 2, the moving center point contacts and breaks through the nozzle of the gas cylinder, and the gas cylinder releases high-pressure gas to inflate the safety balloon 1 through the balloon inflation port 15 of the cylinder opening fixator 3.

[0035] The bottle mouth end of the above-mentioned gas cylinder 2 extends into the cylinder opening fixator 3 and is threadedly connected to the cylinder opening fixator 3.

[0036] The above-mentioned 9-axis inclination sensor 8 is respectively connected to the power supply 7 and the on-off switch 5. The other end of the on-off switch 5 is connected to the power supply wire 4-4 of the telescopic electromagnetic clutch 4, and the power supply 7 is connected to the power-on safety switch 6 in the female buckle through the power supply connection wire 11.

[0037] The other end of the above-mentioned outer shell 4-2 is provided with a sealing plug 4-5. A second sealing thread 4-6 is arranged between the sealing plug 4-5 and the outer shell 4-2, which plays a role in connection and fixation and also plays a sealing role, ensuring that the gas in the fixed mechanism cavity does not leak.

[0038] A first sealing thread 4-3 is arranged on the outer circumference of the moving center point end of the above-mentioned outer shell 4-2, which plays a role in connection and sealing. Since there is a gap between the moving center point and the inner ring of the outer shell, the gas can only be inside the telescopic electromagnetic clutch and cannot leak out.

[0039] The above-mentioned 9-axis inclination sensor is a prior art.

[0040] The working process of the present invention: First, when the elderly person stands, fasten the waistband, connect through the cooperation of the female buckle 9-2 and the male buckle 9-1, and turn on the power supply. When the elderly person falls, the 9-axis inclination sensor 8 (3 dimensions of acceleration, 3 dimensions of angular velocity, 3 dimensions of attitude angle) transmits a signal to the telescopic electromagnetic clutch 4. The telescopic electromagnetic clutch will trigger and break through the nozzle of the gas cylinder 2, and the gas will fill the entire balloon through the balloon inflation port 15 of the cylinder opening fixator 3 to form a protective balloon. As Figure 5As shown, it can protect the waist and hip of the elderly, avoid fractures in the legs and hips of the elderly, loosen the belt buckle when not in use, disconnect the power supply, and the attitude sensor stops working.

[0041] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
