[0026] As Figures 1 to 8As shown in the figure, a wearable airbag connecting device includes an airbag garment 1, the airbag garment 1 is provided with an inflator bottle 2, one end of the inflator bottle 2 is provided with a striker 3, the striker 3 is fixedly connected with a first pull rope 4 away from one end of the inflator bottle 2, one end of the first pull rope 4 is fixedly connected with a sliding rod 5, the sliding rod 5 is slidably connected with a sliding sleeve 6, one end of the sliding rod 5 in the sliding sleeve 6 is fixedly connected with an opening and closing piece, one end of the sliding sleeve 6 close to the first pull rope 4 is symmetrically rotatably connected with a rotary fixing mechanism, each rotary fixing mechanism is sleeved with a second pull rope 7, the other end of the second pull rope 7 is fixedly connected with a connecting rope 8, the connecting rope 8 is fixedly connected with a fixed buckle 9, wherein the gap between the sliding rod 5 and the sliding sleeve 6 is provided with a liquid medium.

[0027] When using the device, the fixed buckle 9 is fixed on the car, the fixed buckle 9 makes the sliding sleeve 6 relative fixed through the connecting rope 8 and the second pull rope 7, the driver wears the airbag garment 1 on the body, when the driver forgets to take off the fixed buckle 9 from the car when getting off the car, the driver will move the first pull rope 4, the first pull rope 4 moves to drive the sliding rod 5 to move, the sliding rod 5 moves to drive the opening and closing piece to move, when the opening and closing piece moves to the rotary fixing mechanism, it will drive the second pull rope 7 to separate from the rotary fixing mechanism, so as to avoid the situation that the first pull rope 4 drives the striker 3 to make the inflator bottle 2 inflate the airbag garment 1 when the driver forgets to take off the fixed buckle 9, prevent mis-triggering, avoid invalid use of the inflator bottle 2, reduce waste, when an accident occurs, the liquid medium will make the opening and closing piece close, the sliding rod 5 and the sliding sleeve do not move relative to each other, the second pull rope is fixed with the rotary fixing mechanism, so that the first pull rope triggers the striker to make the inflator bottle inflate the airbag garment, ensuring the safety of the driver.

[0028] In one embodiment, as shown in Figure 7 and Figure 8 The opening and closing piece includes a sliding plate 10 fixedly connected to the sliding rod 5, a plurality of through holes 11 are formed in the sliding plate 10, mounting grooves 12 are formed in positions close to the through holes 11 of the sliding plate 10, springs 13 are fixedly connected in the mounting grooves 12, fixed seats 14 are fixedly connected in positions away from the mounting grooves 12 of the through holes 11, rotating shafts 15 are rotatably connected to the fixed seats 14, opening and closing plates 16 are fixedly connected to the rotating shafts 15, and the other ends of the springs 13 are fixedly connected with the opening and closing plates 16.

[0029] When the driver gets off the vehicle and forgets to take off the fixing buckle 9, the moving speed is slow, at this time, the pressure of the liquid medium on the opening and closing plate 16 is less than the elastic force of the spring 13, so that the opening and closing plate 16 does not close the through hole 11, the sliding plate 10 will be moved by the sliding rod 5, the sliding plate 10 moves so that the liquid medium can smoothly pass through the through hole 11, when the sliding plate 10 moves to the rotating fixing mechanism, the rotating fixing mechanism will be separated from the second pull rope 7, avoiding triggering the inflator 2 to inflate the airbag 1. When an accident occurs, the driver will move away from the vehicle at a faster speed, at this time, the pressure of the liquid medium on the opening and closing plate 16 is greater than the elastic force of the spring 13, the liquid medium will push the opening and closing plate 16 to close the through hole 11, the sliding plate 10 will not move to the rotating fixing mechanism, the connecting rope 8, the second pull rope 7 and the first pull rope 4 will be straightened, so as to trigger the striker 3 to inflate the airbag 1 by the inflator 2, ensuring the safety of the driver.

[0030] In an embodiment, as shown in Figures 3 to 6 The rotating fixing mechanism comprises a rotating sleeve 17 rotatably connected to the sliding sleeve 6, a sliding groove 18 is formed in the inner wall of the rotating sleeve 17, a placing groove 19 is formed in the outer wall of the rotating sleeve 17, a push rod 20 is slidably connected to the position of the sliding sleeve 6 in the rotating sleeve 17, a connecting rod 21 is fixedly connected to one end of the push rod 20 in the rotating sleeve 17, the other end of the connecting rod 21 is located in the sliding groove 18 and is slidably connected with the rotating sleeve 17, and a push block 22 is fixedly connected to the outer wall of the rotating sleeve 17.

[0031] In an embodiment, as shown in Figure 4 The width of the push block 22 gradually decreases from the end close to the sliding sleeve 6 to the end away from the sliding sleeve 6.

[0032] In an embodiment, as shown in Figure 3 The side of the sliding sleeve 6 close to the rotating sleeve 17 is fixedly connected with a blocking plate 23, and the position of the blocking plate 23 close to the rotating sleeve 17 is provided with a notch 24.

[0033] In an embodiment, as shown in Figure 3 and Figure 4 The second pull rope 7 is elastic, one end of the second pull rope 7 is annular and located in the placing groove 19, and the other end of the second pull rope 7 is fixedly connected with the connecting rope 8 through the notch 24.

[0034] When the sliding plate 10 moves, the push rod 20 will be moved, the push rod 20 moves to drive the connecting rod 21 to move, the connecting rod 21 slides in the sliding groove 18 and will drive the rotating sleeve 17 to rotate, the rotating sleeve 17 rotates to drive the push block 22 to rotate, the push block 22 rotates to make the second pull rope 7 located in the placement groove 19 rotate, when one end of the second pull rope 7 is in contact with the notch 24 of the blocking plate 23, the blocking plate 23 prevents the second pull rope 7 from continuing to rotate, at this time, the push block 22 moves the second pull rope 7 out of the placement groove 19, and finally the second pull rope 7 is separated from the rotating sleeve 17, so that the mis-triggering is prevented, the invalid use of the inflating bottle 2 is avoided, and waste is reduced.

[0035] In one embodiment, as shown in Figure 8 The diameter of the opening and closing plate 16 is greater than the diameter of the through hole 11, so that the opening and closing plate 16 can completely close the through hole 11.
