Embodiment
A kind of multistage energy absorbing vehicle bumper, thick stick 11 is joined directly together with hydraulic bjuffer 21 before the bumper, so as to realize
The function of one-level energy-absorbing buffering；The Qian Gang left and right ends corner is added with reinforcement 22, and the preceding thick stick 11 is provided with guide groove
12；Reinforcement 22 and hydraulic bjuffer 21 are connected with energy-absorbing plate respectively, and EPP (Expanded are accompanied in energy-absorbing plate
polypropylene)33；Its energy-absorbing plate is connected with telescoping hydraulic cylinder 41, and pressure check valve 42 is set on oil pipe line,
Pressure oil flows into oil return cylinder 43, so as to realize multistage energy-absorbing function；Its last telescoping hydraulic cylinder 41 and body of a motor car side arm 5 are solid
Fixed connection.The hydraulic bjuffer 21 is connected with preceding thick stick 11 and energy-absorbing plate, number be 2 and more than.The retainer ring 31 rises
To clamp EPP and fix 34 numbers of preceding energy-absorbing plate 32 and rear energy-absorbing plate be 3 and more than.The preceding energy-absorbing plate 32 and rear energy-absorbing plate
EPP33 is filled up between 34, three forms energy-absorbing plate.The telescoping hydraulic cylinder 41 is connected with body of a motor car side arm 5 and energy-absorbing plate,
Number be 2 and more than.The check valve 42 has pressure sensitive function, when oil pressure reaches setting value in oil cylinder, unidirectionally
Valve is opened, conversely, being then in normal off status.Its number is equal with the number of telescoping hydraulic cylinder 41.Described 11 liang of side ends of preceding thick stick
Be equipped with groove 12, its role is to when 21 forced compression of hydraulic bjuffer as its movement locus.At the reinforcement 22
It is connected in Qian Gang corners, and with energy-absorbing plate, plays the effect of increase bulk strength.The oil return cylinder 43 be in energy-absorbing plate and
Between body of a motor car side arm 5, play a part of reclaiming hydraulic oil.
1 pair of the utility model is further elaborated below in conjunction with the accompanying drawings.
Before being acted on without external force during thick stick 11, hydraulic bjuffer 21, energy-absorbing plate and telescoping hydraulic cylinder 41 are in normality.
Have external force F act on before thick stick 11 when.When external force F is not very big, thick stick 11 and hydraulic bjuffer 21 before the bumper
And reinforcement is joined directly together, so as to realize the function of one-level energy-absorbing buffering, the reinforcement 22 of both ends corner improves entirety
Intensity；When external force F is bigger, because hydraulic bjuffer 21 and preceding energy-absorbing plate 32 are joined directly together, therefore promote before energy-absorbing plate 32 to
EPP energy-absorbings band 33 is extruded afterwards, and to absorb above unnecessary energy, at this moment energy-absorbing plate can move along groove 12；When external force F is very big
When, if preceding two-stage energy absorption device can not absorb its collision energy, energy-absorbing plate promotes oil cylinder inner carrier motion compresses backward
Hydraulic oil, when oil pressure reaches the set point pressure value of check valve 42 in cylinder, then check valve 42 is opened, telescoping hydraulic cylinder 41
Interior hydraulic oil is pressed into oil inlet and oil return cylinder 43, to buffer and absorb excess energy above.
The utility model principle is clearly simple, has a multistage energy-absorbing function, and all linked with one another between every grade, function is flexibly more
Become, energy caused by car collision the moment of fault can be rapidly and efficiently absorbed, so as to efficiently mitigate or
Avoid driver and crew and automobile body is damaged.
It is described above, only it is the utility model preferred embodiment, does not make scope limitation to the utility model, it is all not de-
From the content of the technical scheme of the utility model, and simply change and improve according to the essence work of technical solutions of the utility model etc.,
Belong to patent protection category of the present utility model.
