Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Embodiment one
The utility model relates to a kind of vehicle collision energy absorber, it comprises the crumple assembly be connected between chassis runner and collision prevention girders, described crumple assembly is connected in series by several crumple portions that can be nested in successively together and forms, and two crumple portion one of arbitrary neighborhood are circumferentially with multiple reduction hole along it.This vehicle collision energy absorber, to be connected in series by several crumple portions that can be nested in successively together to form by making to be connected to crumple assembly between collision prevention girders and chassis runner, and is provided with on two crumple portion one of arbitrary neighborhood and weakens hole.When colliding generation, crumple assembly can carry out controlled crumple nested one by one, can, on the basis of carrying out crumple energy-absorbing, avoid the uncontrollable distortion of crumple assembly to cause damage to surrounding vehicles parts.
Based on design philosophy as above, a kind of example arrangement of the vehicle collision energy absorber of the present embodiment as shown in Figures 1 and 2, wherein for ease of the connection of crumple assembly 3 between collision prevention girders 1 and chassis runner 2, be connected to front mounting plate 4 and rear adapter plate 5 at the two ends of crumple assembly 3.Front mounting plate 4 and collision prevention girders 1 removably connect, and rear adapter plate 5 and chassis runner 2 removably connect.
The structure of front mounting plate 4 as shown in Figure 3, front mounting plate 4 is formed with through hole, is connected in collision prevention girders 1 via bolt 8 to make front mounting plate 4.For ease of the installation of bolt 8, the position that front mounting plate 4 corresponds to each through hole can arrange project-welding nut, and the installation place corresponding to each bolt 8 in collision prevention girders 1 also can be formed with groove, thinks that mounting tools provides operational space.Also be formed with front mounting plate flange 41 at the edge of front mounting plate 4 in the present embodiment, when front mounting plate 4 is connected with crumple assembly 3, front mounting plate flange 41 points to the side of crumple assembly 3.
The structure of rear adapter plate 5 as shown in Figure 4, adapter plate flange 51 after the edge of rear adapter plate 5 is also provided with, rear adapter plate flange 51 points to the side of crumple assembly 3 equally, and be also connected with in box-like connecting portion 6 on a side end face of rear adapter plate 5, connecting portion 6 can and chassis runner 2 between be socketed, and removably connecting between adapter plate 5 and chassis runner 2 after can being realized by the attaching parts be located between rear adapter plate 5 and chassis runner 2.On connecting portion 6, be provided with connecting bore 61 in the present embodiment, and above-mentioned attaching parts can be the tie bolt 7 be arranged between rear adapter plate 5 and chassis runner 2.Certainly except tie bolt 7, attaching parts also can adopt other structure such as bearing pin or pin.
Except the edge at front mounting plate 4 and rear adapter plate 5 as above all arranges turnup structure in the present embodiment, certainly also only flange can be provided with on front mounting plate 4 and rear adapter plate 5 one.And when front mounting plate 4 and after adapter plate 5 is provided with flange, and front mounting plate 4 and rear adapter plate 5 are when being connected to the two ends of crumple parts 3, the projection of rear adapter plate 5 on front mounting plate 4 in the present embodiment, is also made to be positioned within the front mounting plate flange 41 on front mounting plate 4.At crumple assembly 3, crumple can occur thus, and when front mounting plate 4 is contacted with rear adapter plate 5, rear adapter plate 5 can insert in front mounting plate 4, to limit the distortion 3 of crumple assembly.
The structure of crumple assembly 3 as shown in Figure 5, the crumple portion of crumple assembly 3 is formed by tapered taper crumple unit in the present embodiment, and be connected to the isometrical crumple unit composition of taper crumple unit one end, be connected with taper crumple unit by adjacent isometrical crumple unit between each crumple portion, can realize the nested one by one of each crumple portion thus, and aforesaid reduction Kong Ze is arranged on taper crumple unit.For ease of statement, each taper crumple unit and isometrical crumple unit are referred to as the first taper crumple unit 31, first isometrical crumple unit 32, second taper crumple unit 33 and the second isometrical crumple unit 34, wherein be provided with on the first taper crumple unit 31 and the second taper crumple unit 33 and weaken hole 35, the sectional dimension of the second taper crumple unit 33 is greater than the first taper crumple unit 31, and the quantity in now crumple portion is only the use of exemplary statement, in actual design, the quantity in crumple portion can freely be chosen as required.Certainly, except being made up of taper crumple unit and isometrical crumple unit, also can make the taper crumple unit that crumple portion is only tapered in the present embodiment, each taper crumple unit composes in series crumple assembly 3 mutually, and on two taper crumple unit one of arbitrary neighborhood, arrange reduction hole 35.Also or the gauge structure such as crumple portion also can be made in the present embodiment to be only, make whole crumple assembly 3 in step-like.
For the crumple portion be made up of taper crumple unit and isometrical crumple unit, the crumple process of crumple assembly 3 as shown in Figure 6, when collision prevention girders 1 is subject to extraneous shock, second taper crumple unit 33 can crumple distortion enter in the second isometrical crumple zones 34, first isometrical crumple zones 32 can enter in the space that the second taper crumple unit 33 and the second isometrical crumple unit surround, and the first taper crumple unit 31 can enter in the first isometrical crumple unit 32 in crumple distortion.In whole crumple process, the first taper crumple unit 31 and the second taper crumple unit 33 are main crumple zones, and the first isometrical crumple unit 32 and the second isometrical crumple unit 34 also can deform absorption collision energy.Due in collision process, each crumple unit is for nest together one by one, thus stacking crumple portion does not take whole crumple distance, stacking crumple portion also can be limited in certain scope, and due to the turnup structure on front mounting plate 4 and rear adapter plate 5, and rear adapter plate 5 can insert within the front mounting plate flange 41 of front mounting plate 4, also can limit the distortion of stacking crumple assembly 3, thus avoid impacting the vehicle part of surrounding.
