The invention discloses an automobile crash buffer device. The automobile crash buffer device is used for being mounted at the position where an automobile is likely to be crashed. The automobile crash buffer device comprises a first buffer air bag (1), a second buffer air bag (2), a third buffer air bag (3) and a pressure relief air bag (4) which are sequentially and adjacently arranged from front to back. The first buffer air bag (1) is communicated with the second buffer air bag (2) through a first buffer hole (11). The second buffer air bag (2) is communicated with the third buffer air bag (3) through a second buffer hole (21). The third buffer air bag (3) is communicated with the pressure relief air bag (4) through a third buffer hole (31). The pressure relief air bag (4) is communicated with the outside through a pressure relief hole (41). The first buffer hole (11), the second buffer hole (21) and the third buffer hole (31) are each provided with a pressure limiting opening mechanism (5). The pressure limiting opening mechanisms (5) enable the corresponding buffer holes to be opened only after the pressure in the buffer air bags at the front ends of the pressure limiting opening mechanisms reaches the set value. The automobile crash buffer device has the advantages that when the automobile is crashed, the safety of a driver and passengers can be guaranteed, and the damage to the automobile is also small.
