Enough understand, mutually extruded by external force between the first crumple part 1 and the second crumple part 2 in the case of can disconnecting,
First crumple part 1 and the second crumple part 2 can also use other connection modes to be attached, such as will by way of spot welding
First crumple part 1 is connected together with the second crumple part 2.
As shown in Figure 1, Figure 2 with two the first rivets as locating part shown in Fig. 6, are provided with the right end of the first crumple part 1
11, for the distance that when the first crumple part 1 and the second crumple part 2 disconnect, the second crumple part 2 of limitation is moved to the left, make
Second crumple part 2 is moved relative to the first crumple part 1 in pre-determined distance.Specifically, the right end of the first crumple part 1 is provided with two
A through hole, two the first rivets 11 are riveted together through the through hole with the first crumple part 1.In addition, those skilled in the art are also
Appropriate adjustment can be carried out to the quantity of the first rivet 11 on the premise of locating part intensity is ensured, it is specific to be applicable in
Application scenario.Further, those skilled in the art can also be as needed, uses locating part (such as the column of other structures form
Shape structure), and by setting at the right end position of the first crumple part 1.Or those skilled in the art can also be by locating part
It is arranged to an entirety with the first crumple part 1.
As shown in Figure 4 and Figure 5, the first crumple part 1 is provided with warp architecture 12 at the position close to the first rivet 11, uses
In making direction (Fig. 4 shown under of the first crumple part 1 when the extruding force on by longitudinal direction reaches preset value along setting
Side) flexural deformation.In addition, those skilled in the art can also be as needed, corresponding bending knot is set on the second crumple part 2
Structure so that the second crumple part 2 also can be along the direction flexural deformation of setting in stress.Skilled artisans appreciate that
It is, when the second cross beam 5 of right end in the first crossbeam 4 and Fig. 4 of left end in Fig. 4, when mutually being extruded by collision, the first crumple part 1
The energy of collision process generation can be absorbed by the process of warp architecture 12 along the direction flexural deformation of setting.
In addition, as shown in Figure 1, the utility model additionally provides a kind of stent of high-tension distribution box for electric vehicle, the stent
It is located at cabin of electric automobile including first crossbeam 4, second cross beam 5 and above-mentioned induction type crumple energy absorption device, first crossbeam 4
Front portion, second cross beam 5 are located at the rear portion of cabin of electric automobile, and the length direction of first crossbeam 4 and second cross beam 5 with it is electronic
The width of automobile is parallel.It will be appreciated to those of skill in the art that first crossbeam 4 and second cross beam 5 can be used for fixing
Or other parts such as the air-conditioner controller, electric machine controller, entire car controller of electric automobile are installed.
Fig. 1 is continued to participate in, the first crumple part 1 is bolted on first crossbeam 4, and the second crumple part 2 passes through bolt
Fixed on second cross beam 5.The PDU (not shown)s of electric automobile are fixed to two induction type crumples shown in Fig. 1
On energy absorption device (such as first crumple part 1).
As shown in Figures 4 to 6, when head-on crash occurs for electric automobile, the front deck stress of electric automobile deforms, and makes
The first crossbeam 4 obtained inside front deck is mobile (close to the direction of second cross beam 2) backward.In the process that first crossbeam 4 is moved rearwards
In, the first crumple part 1 and 2 stress of the second crumple part mutually extrude, and under this force, the second rivet 3 is by relative motion
Shearing force cut-out between first crumple part 1 and the second crumple part 2.First crossbeam 4 drives the first crumple part 1 to continue to be moved back
It is dynamic so that the left end of the second crumple part 2 offsets with two the first rivets 11.At this time, the first crumple part 1 first crossbeam 4 into
It can be bent under the compression of one step at warp architecture 12 along vertically downward direction (lower section of Fig. 4).Therefore, sent out in electric automobile
During raw head-on crash, the induction type crumple energy absorption device of the utility model can make the PDU of electric automobile first in the horizontal direction to
After move, then move vertically downwards again, so as to avoid electric automobile occur head-on crash when PDU touched with front
The parts of the part and top of hitting deformation collide impaired phenomenon.
