Description

Technical Field

[0001] The utility model relates to the technical field of automobile safety airbags, in particular to a buffer type automobile safety airbag. Background Art

[0002] Existing cushioning automobile airbags are mainly used to protect the safety of passengers in the event of a car collision. When a car collides violently, the collision sensor installed on the car will detect the sudden change in vehicle acceleration. The sensor will send a signal to the airbag control unit. After receiving the signal, the airbag control unit will quickly trigger the gas generator. The chemical substances in the gas generator will produce a large amount of nitrogen in a short period of time to fill the airbag and provide collision protection for the driver.

[0003] However, when in use, the existing airbag will deflate immediately after inflation, and cannot continue to provide cushioning protection for the occupants in the car, which will increase the risk of secondary injury. It also does not have a multi-level cushioning effect and cannot more effectively reduce the transfer of collision energy to the human body. The human body will directly collide with the popped-out airbag, and the collision energy will be transferred to the human body in a more concentrated manner. Utility Model Content

[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide a cushioning automobile airbag. When the airbag is inflated, since the cylindrical airbag is closer to the output end of the gas generator, it will be filled with the airflow first, which can first provide a preliminary cushioning protection for the occupants in the car and reduce the risk of injury. During this period, the sealing piece will be pushed to the top of the cylindrical airbag by the airflow, and the gas will continue to rise, which will push up the sealing plate to open the inflation hole 1 and inflate the inside of the plane airbag. After the inflation of the plane airbag is completed, due to the continued increase of gas, the sealing piece will be pushed back to the bottom of the cylindrical airbag to close the bottom, and then the sealing plate will be re-attached to the inflation hole 1 under the action of air pressure, thereby The air inside the cylindrical airbag is simply sealed to slow down the deflation rate, which means that for a period of time after the collision, it can continue to provide cushioning protection for the occupants in the car to prevent secondary injuries. The cushioning automobile airbag forms a graded cushioning mechanism by setting up an external airbag and an internal flat airbag and a cylindrical airbag. First, the cylindrical airbag and the flat airbag are filled with air first, which will absorb and disperse part of the collision energy. Then, after the outer airbag is filled with air, it will further cushion the remaining impact force. This graded cushioning method can more effectively reduce the transmission of collision energy to the human body, so that the impact force borne by the occupants is more evenly distributed on various parts of the body, reducing serious injuries caused by excessive local force.

[0013] Beneficial effects

[0014] 1. Compared with the existing technology, when the cushioning automobile airbag is inflated, the cylindrical airbag is closer to the output end of the gas generator and will be filled with air first. It can provide a preliminary cushioning protection for the occupants in the car first and reduce the risk of injury. During this period, the sealing piece will be pushed to the top of the cylindrical airbag by the airflow. The gas continues to rise, which will push up the sealing plate to open the inflation hole 1 and inflate the interior of the planar airbag. After the inflation of the planar airbag is completed, due to the continued increase of gas, the sealing piece will be pushed back to the bottom of the cylindrical airbag to close the bottom. Then, the sealing plate will be re-attached to the inflation hole 1 under the action of air pressure, thereby simply sealing the air inside the planar airbag and the cylindrical airbag, slowing down the deflation speed. This means that for a period of time after the collision, it can continue to provide cushioning protection for the occupants in the car to prevent secondary injuries.

[0015] 2. Compared with the existing technology, this cushioning automobile airbag forms a graded cushioning mechanism by setting up an external airbag and an internal flat airbag and cylindrical airbag. First, after the cylindrical airbag and the flat airbag are filled with air, they will absorb and disperse part of the collision energy. Then, after the outer airbag is filled with air, it will further cushion the remaining impact force. This graded cushioning method can more effectively reduce the transmission of collision energy to the human body, so that the impact force borne by the occupants is more evenly distributed among various parts of the body, reducing serious injuries caused by excessive local force.
