The utility model is described in further detail with specific embodiment with reference to the accompanying drawing.
The installation leg structure of controller, is still illustrated by taking gearbox control TCU1 as an example in the utility model.Such as
Shown in Fig. 1, the TCU1 has encapsulating housing, and the surrounding of shell is formed there are five installation foot 2, and installation foot 2 is in the form of a column, Mei Gean
It is provided with the screw hole passed through for the screw 7 of connection TCU1 and gearbox 3 on dress foot 2, the screw hole that installation foot uses at present is
Round hole.Can be from fixed position when the unidirectional external force that if controller is subject to when frontal impact occurs is more than given threshold power
It completely disengages
If frontal impact occurs for vehicle, the unidirectional external force N in front that TCU1 is subject to be more than or equal to given threshold power (such as
30kN), the requirement being smoothly detached to can satisfy TCU1 with gearbox 3, this just needs to play connection when TCU1 stress and makees
Screw 7 can be cut, and such TCU1 can integrally be detached from gearbox 3, and screw is cut suffered shearing
No more than given threshold power 30kN.In this case, if the screw 7 in five round holes is allowed to be cut simultaneously,
The unidirectional external force that TCU1 is subject to generally requires very big (frontal impact situation very serious), experiments verify that being far longer than setting
Threshold force (such as 30kN).
In view of the foregoing, in the present embodiment, the screw hole on five installation feet 2 is using round hole 6+ kidney slot 4+ half
The composite structure of open bore 5, and the long axis of kidney slot 4, on the action direction of the unidirectional external force of frontal impact, half-open discharge hole 5 is opened
Mouth is contrary with the unidirectional external force of frontal impact, can thus allow five screws 7 to be sheared stage by stage, to be cut one by one
It is disconnected.If Fig. 3 to Fig. 7 show the schematic diagram of one to No. five installation foot, a screw hole is half-open discharge hole 5 on five installation feet 2,
One screw hole is round hole 6, and three screw holes are kidney slot 4, wherein the length of two kidney slots is identical in three kidney slots 4
And it is greater than the length of another kidney slot.
Since the aperture of round hole 6 is smaller, the gap between screw 7 and hole wall is small, therefore, when the screw 7 in round hole 6
Hole wall contact start stress with round hole is during cutting, and half-open discharge hole 5 or kidney slot 4 are due to screw 7 to hole
The gap of wall is larger, therefore encounters not yet, therefore unidirectional external force N largely can be with screw 7 of the independent role in round hole 6
On, guarantee that the screw 7 can be taken the lead in cutting in this way.And half-open discharge hole 5 is since side is unclosed, and is open and frontal impact list
Outward force it is contrary, installation screw 7 inside it, which does not need to be cut, in this way can be detached from TCU1.

Show, be the first to the 5th installation foot by sequence numbers five installation feet 2 in figure, be described as follows:
When the non-stress of TCU1, as shown in step1, all screws 7 are not contacted with the hole wall of place screw hole；
Screw 7 and round hole after TCU1 starts stress, as shown in step2, in the 5th installation foot first in round hole 6
Hole wall contact, and gradually by shearing action until final round hole 6 in screw 7 cut, screw 7 is broken when institute
It is F by shearing1, shearing F1Less than given threshold power 30kN；
After the screw 7 of 5th installation foot is broken, the spiral shell as shown in step3, in the first installation foot in the short kidney slot 4 of length
Nail 7 takes the lead in contacting with right side hole wall, since the screw 7 on the second to the 4th installation foot is not contacted with hole wall, therefore the first installation
Screw 7 in foot bears most shearing action until finally being cut, and screw 7 is suffered when being broken to be sheared less than setting
Threshold force 30kN；
Next, the screw in third installation foot and the 4th installation foot in kidney slot 4 connects with hole wall as shown in step4
Touching, the two is jointly by shearing action until finally cut, and suffered shearing is F when screw is broken in each kidney slot2If
Threshold force is determined greater than 2F2, as shown in step5, since the second installation foot is using half-open discharge hole, and it is open and frontal impact list
Outward force it is contrary, so screw therein be not necessarily to by cut can be detached from TCU1.
It should be noted that in the above-described embodiments, the screw installed in usual screw hole is identical, round hole in screw hole
Quantity be m, suffered shearing is F when screw is broken in a round hole1, screw occurs suffered by fracture simultaneously in round hole
The shearing mF arrived1Less than given threshold power；The quantity of kidney slot is n in the screw hole, and screw occurs disconnected in a kidney slot
Suffered shearing is F when splitting2, screw is broken suffered shearing nF simultaneously in kidney slot2Less than given threshold power.Due to spiral shell
Nail Stage loading is simultaneously cut, therefore under normal conditions, is cut the unidirectional external force that the screw in all round holes is applied and wanted
The unidirectional external force applied greater than the screw cut in all kidney slots.
Although in the present embodiment, the screw hole of five installation feet is using a round hole, a half-open discharge hole and three
The combining form of kidney slot, but those skilled in the art can change installation foot with effect is connected and fixed with coupling disengaging condition
