Please in conjunction with consulting shown in Fig. 4 to 8, the utility model provides a kind of car body component, it comprises body rail member 1 and installing component 2, similarly, body rail member 1 arranges attachment rail 10, installing component 2 is fixed in the attachment rail 10, attachment rail 10 is for running through the elongated slot of body rail member 1, installing component 2 comprises with the first 21 of elongated slot free-running fit with greater than the second portion 22 of elongated slot, first 21 is fixing with second portion 22, and second portion 22 is resisted against around the elongated slot of body rail member 1.
Car body component comprises a plurality of installing components 2, and each of a plurality of described installing components 2 can be fixed in the attachment rail 10 respectively, and the installing component 2 that is fixed in the attachment rail 10 is one of them of described a plurality of described installing components 2.For example, Fig. 4 to 6 shows an installing component 2, and Fig. 8 shows another installing component 2 '.Below by for instance bright a plurality of installing component 2 of this another installing component 2 ', 2 ' composition situation.In Fig. 4 to 6, the distance B between two mounting hole 20A, the 20B
ABBe a0, it is a fixed value, and the center of the mounting hole 20A on the left side is to the distance B at the left end edge of installing component 2
LBe b1, the center of the mounting hole 20B on the right is to the distance B at the right-hand member edge of installing component 2
RBe c1.In Fig. 8, the distance B between two mounting hole 20A ' and the 20B '
AB' also be fixed value a0, the center of the mounting hole 20A ' on the left side is to the distance B at the left end edge of installing component 2 '
L' be b2, the center of the mounting hole 20B ' on the right is to the distance B at the right-hand member edge of installing component 2 '
R' be c2.B1 is not equal to b2, and c1 is not equal to c2, but b1+c1=b2+c2 that is to say that a0, the b1 of the installing component 2 shown in Fig. 4 to 6 and c1 sum equate with a0, b2 and the c2 sum of installing component 2 ' shown in Figure 8.
In the utility model, car body component comprises a plurality of installing components 2,2 ', and each installing component 2,2 ' first 21,21 ' profile are identical, thereby a plurality of installing component 2,2 ' can match with attachment rail 10 interchangeably.Each installing component 2,2 ' arranges two mounting hole 20A, 20B, 20A ', 20B ', separately two mounting hole 20A, 20B of a plurality of installing components 2,2 ', the distance between 20A ', the 20B ' all equate, but two mounting hole 20A, 20B, 20A ', the 20B ' position on a plurality of installing components 2 are different.Owing to the distance B between two mounting holes
AB, D
AB' etc. remain unchanged, be always a0, can be well be complementary with the installation dimension that requires that suspends of dynamic assembly.Provide the mounting hole on the left side of a plurality of installing components to the distance B at installing component left end edge
L, D
L' etc. be respectively b1, b2 etc., the distance B at the mounting hole installing component right-hand member edge on the right simultaneously
R, D
R' etc. also will change thereupon, be designed to respectively c1, c2 etc., only need b1+c1=b2+c2=bn+cn(wherein n represent that a plurality of installing components can be a plurality of arbitrarily for what determine as required.), in other words, distance between the edges at two ends on a plurality of installing component 2 each comfortable longitudinally is definite value, perhaps the first 21 of each installing component, 21 ' etc. profile are identical, thereby, can satisfy the variation of installation site of the length direction that is suspended at attachment rail 10 of different configuration dynamic assemblies, provide suitable installing component to install and suspend.Therefore, can realize the installation site variable adjustment within the specific limits that suspends, satisfy the demand of high decoupling zero rate, thereby obtain better NVH performance.
The beneficial effect that the utility model has is: stamp out attachment rail 10 by the adjustable interval, the installation site that suspends on body rail member 1, designing simultaneously installing component 2 cooperates with it, thereby so that mounting hole 20A, 20B can change the position on installing component 2 continuously, form thus the assembly of a series of different models, can satisfy well the demand of the suspended position adjustment of supporting power assembly system.Such design not only can solve the design problem of a cover vehicle body different dynamic assembly suspended position demand well, also can solve well and make the technical barrier that processing differences causes actual position off-design required value.
The above specific embodiment only is used for explanation the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that does not break away from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
