[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0025] Reference Figure 1 , an anti-fall warning device for the elderly, comprising a waist support belt 1, an anti-fall mechanism 2 and an early warning mechanism 3. The early warning mechanism 3 is fixedly arranged at one end of the waist support belt 1 along its length direction, and the early warning mechanism 3 controls the anti-fall mechanism 2 through an electrical connection. When the elderly body tilts, the early warning mechanism 3 is triggered, and then the anti-fall mechanism 2 is triggered, so as to protect the human body and reduce the harm to the elderly body.
[0026] Reference Figure 1 The waist support belt 1 is in a ring shape and includes a belt body 11. The belt body 11 is respectively provided with elastic bands 12 at both ends along its length direction. The two elastic bands 12 can be fixed by Velcro 13. Moreover, a plurality of ventilation holes 14 are evenly opened on the side of the waist support belt 1 close to the human body.
[0027] Reference Figure 1 and Figure 2 The anti-fall mechanism 2 includes an airbag component 21 and a shock absorbing component 22. Figure 1 and Figure 3 The airbag assembly 21 includes an airbag 211, an air circuit 212 and a gas cylinder 213. The airbag 211 is evenly spaced and arranged in two layers and in a spring shape. The air circuit 212 is located in the belt body 11. The gas cylinder 213 is fixedly arranged at one end of the belt body 11 away from the warning mechanism 3. The airbag 211 and the gas cylinder 213 are fixedly connected by the air circuit 212 and the airbag 211, the air circuit 212 and the gas cylinder 213 are connected. Figure 4 The belt body 11 is provided with a protruding opening 15 for the airbag 211 to pop out along the side away from the human body.
[0028] Reference Figure 2 and Figure 3 , there are multiple shock absorbing components 22, and multiple shock absorbing components 22 are evenly fixed on the belt body 11 below the airbag 211. The shock absorbing component 22 includes a fixing plate 221 and a shock absorbing spring 222. There are two fixing plates 221, wherein the two fixing plates 221 are symmetrically fixed on the belt body 11 along the thickness direction of the belt body 11, and both ends of the shock absorbing spring 222 along the length direction thereof are perpendicular to the two fixing plates 221 and fixedly connected thereto, and a sponge 223 is fixed on the side of the fixing plate 221 away from the airbag 211, and the length of the shock absorbing spring 222 when not compressed is longer than the thickness of the airbag 211 when not folded in use.
[0029] When an elderly person falls, the anti-fall mechanism 2 will be triggered. Due to the inertia of the human body when falling, the part close to the buttocks will touch the ground first. Therefore, the sponge 223 will touch the ground first and then compress the shock-absorbing spring 222. At the same time, the airbag 211 will also be quickly inflated and popped out from the extension port 15, providing multiple cushioning for the human body and thus protecting the elderly.

The input end of the processor 31 is connected to the acceleration sensor and the gyroscope sensor 34 respectively, and the output end of the processor 31 is connected to the gas cylinder 213 and the buzzer 32 respectively. The processor 31 can make the compressed gas in the gas cylinder 213 continuously enter the airbag 211 to inflate it. The processor 31 is also electrically connected to the mobile terminal. The GPS locator 35 and the heart rate sensor 36 are electrically connected to the processor 31 respectively. A protective box 37 is also fixed to the outside of the early warning mechanism 3.
[0031] When in use, the elderly put the waist support belt 1 on the waist and fix the elastic band 12 with Velcro 13 so that the waist support belt 1 is worn on the waist. When the elderly fall, the acceleration sensor 33 will sense the change in human body speed, and the gyroscope sensor 34 will sense the tilt of the human body angle, which can be immediately synchronized to the processor 31. The processor 31 will trigger the buzzer 32 to sound an alarm, and at the same time, the gas in the gas cylinder 213 will be quickly filled into the airbag 211 to protect the human body. At the same time, the shock-absorbing spring 222 and the sponge 223 can also play a buffering role for the human body. In addition, when a fall occurs, the wearer's caregiver can know the wearer's specific position and heart rate changes through the mobile terminal, which is convenient for quickly understanding and rescuing the wearer's situation.
[0032] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments.
