The airbag can quickly inflate to form a buffer during a vehicle collision, reducing the force of the occupants colliding with the vehicle interior structure, thereby reducing the degree of injury to the occupants.

[0003] In the prior art, during the use of an escape airbag, an internal power-on explosion of a gas generator generates gas to quickly fill the inside of the airbag, causing the airbag to expand. There is still a certain impact force at the moment when the airbag expands rapidly, which may cause impact injuries to the face of the driver. Therefore, the present application designs a structure of an escape airbag. Summary of the Utility Model

Specific embodiments

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the accompanying drawings.

[0024] An embodiment of the present utility model discloses a structure of an escape airbag.

[0025] The present utility model provides an escape airbag structure as shown in Figures 1-3 which includes a box body 1, a connecting plate 2, a gas generator 3, a pressure relief box 4 and an airbag 5. The connecting plate 2 is fixedly connected to the top end of the box body 1. The gas generator 3 is fixedly connected to the inner wall of the bottom end of the box body 1. The pressure relief box 4 is fixedly connected to the upper surface of the gas generator 3. The airbag 5 is fixedly connected to the top end of the pressure relief box 4. An opening is provided in the inner wall of the connecting plate 2. An exhaust port is provided on the side wall of the pressure relief box 4. A pressure relief cylinder 10 is fixedly connected to the side wall of the pressure relief box 4 at the exhaust port. A piston block 11 is slidably arranged in the inner wall of the pressure relief cylinder 10. A spring 13 is fixedly connected to the side wall of the piston block 11. The end of the spring 13 away from the piston block 11 is fixedly connected to the inner wall of the pressure relief cylinder 10. A guiding rod 12 is fixedly connected to the side wall of the piston block 11. The rod wall of the guiding rod 12 is slidably arranged in the inner wall of the pressure relief cylinder 10. A pressure relief hole is provided on the cylinder wall of the pressure relief cylinder 10.

[0026] A fixing rod 6 is fixedly connected to the inner wall of the connecting plate 2 located at the opening, a rotating plate 7 is rotatably connected to the rod wall of the fixing rod 6, a side wall of the rotating plate 7 is slidingly set on the inner wall of the connecting plate 2 located at the opening, a crushing block 8 is fixedly connected to the side wall of the rotating plate 7, and one end of the crushing block 8 facing away from the rotating plate 7 is fixedly pasted on the inner wall of the connecting plate 2 located at the opening, and a baffle 9 is fixedly connected to the inner wall of the box body 1, and the baffle 9 is inclined.

[0027] When in use, the connecting plate 2 can make the box body 1 fixedly installed on the vehicle body. When an accident occurs, the powder grinder inside the gas generator 3 is energized and explodes to produce excessive gas. The gas enters the airbag 5 through the pressure relief box 4, causing the airbag 5 to expand and push up the rotating plate 7 to rotate along the rod wall of the fixed rod 6. When the rotating plate 7 rotates, the crushing block 8 is pulled and crushed by the rotating plate 7 so that the rotating plate 7 can rotate normally, thereby allowing the airbag 5 to be removed to the outside of the box body 1. When the human body contacts and collides with the airbag 5, the air pressure inside the airbag 5 increases. In order to allow the airbag 5 to provide further buffering treatment to the human body, the over-pressure gas will push the piston block 11 to slide along the inner wall of the pressure relief cylinder 10 to push the spring 13 to compress, so that the guide rod 12 moves, and the piston block 11 moves stably, so that the gas can be discharged through the pressure relief hole on the pressure relief cylinder 10, which can improve the buffering effect of the airbag 5.

[0028] In order to improve the damping effect of the movement of the guide rod 12, as Figures 1-3 As shown, one end of the guide rod 12 facing away from the piston block 11 extends to the outside of the pressure relief cylinder 10 and is fixedly connected to a transfer block 14, the inner wall of the box body 1 is fixedly connected to a transfer seat 15, a power supply 16 and an alarm 17 are fixedly connected to the side wall of the box body 1, and the connection terminals of the power supply 16 and the alarm 17 extend to the inside of the transfer seat 15 respectively, the transfer block 14 is plugged into the inside of the transfer seat 15, and a rubber damping ring 18 is fixedly connected to the inner wall of the pressure relief cylinder 10, and the inner wall of the rubber damping ring 18 is fitted on the rod wall of the guide rod 12.

[0029] The guide rod 12 continuously moves to push the adapter block 14 to move and extend to the inside of the adapter seat 15, so that the alarm 17 and the power supply 16 can be powered on to alarm, which is convenient for recording the pressure relief situation. The rubber damping ring 18 can improve the damping effect of the movement of the guide rod 12 to prevent the guide rod 12 from excessive movement.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
