Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.
[0026] Such as figure 1 As shown, what the present invention described is the front double air chamber safety airbag, which can be stored in the steering wheel after being folded according to different automobile structures. Including driver's side airbag 1, steering wheel side airbag 2, one-way inflation valve between airbags 3, airbag inflation device 4, steering wheel side airbag exhaust valve 5, driver's side airbag exhaust valve 6 and PLC. The airbag 1 on the driver's side and the airbag 2 on the steering wheel side can be made of a single layer of woven fabric. The steering wheel side airbag 1 and the driver's side airbag 2 form a series structure, and are not connected when the airbag is not working. The steering wheel side airbag 2 is connected to the airbag infl...

The invention discloses an anti-breakdown front double air chamber airbag and a control method thereof. The airbag comprises a steering wheel side safety airbag, a driver side safety airbag, an airbaginflating device and a PLC control device, wherein the steering wheel side safety airbag and the driver side safety airbag are connected in series, a one-way valve is arranged between the steering wheel side safety airbag and the driver side safety airbag, the one-way valve is opened when the airbag is inflated, the steering wheel side safety airbag and the driver side safety airbag are communicated with each other, the one-way valve is closed after the air bag is inflated, and the steering wheel side safety airbag and the driver side safety airbag are relatively independent; the driver sidesafety airbag and the steering wheel side safety airbag are both inflated by the airbag inflating device, the PLC is connected with the airbag inflating device, and when a collision occurs, the airbaginflating device is controlled to inflate the steering wheel side safety airbag and the driver side safety airbag. The anti-breakdown front double air chamber airbag and the control method thereof have the advantages that the front and back airbags are arranged, the collision can be buffered from light to heavy when the collision occurs, the driver side safety airbag performs first collision buffering on a driver, and the steering wheel side safety airbag performs second collision buffering so that the collision energy of a human body can be absorbed as much as possible, thereby achieving thebest safety protection.
Description
technical field [0001] The invention belongs to the technical field of vehicle driving safety, and in particular relates to a puncture-proof safety airbag with front and rear double air chambers. Background technique [0002] In recent years, with the gradual popularization of automobiles in families, the safety of drivers and occupants of automobiles has attracted increasing attention. In our country, the improvement of automobile safety has become an important factor in the development of the transportation industry and the automobile industry. Further research on automobile safety is very important and necessary for the development of automobile industry. [0003] There are many kinds of automobile collision accidents, which can be divided into several main types such as frontal collision, side collision, rear-end collision and rollover (or rollover). Frontal collision accounts for the largest proportion, so it is the focus of our research on automobile passive safety. ...
