[0012]
FIG. 2 is an enlarged perspective view showing a fitting structure of each of the parts A to D in FIG. FIG. 2A shows a fitting structure of the airbag bracket 6 of the part A in FIG. 1 to the CCB 1. In this case, the male-shaped part 100 is formed in the bracket 6 for airbags, and the female-shaped part 200 is formed in CCB1. By pushing this bracket 6 as shown by the arrow in the figure, the bracket 6 Male and female are fitted with CCB1. The CCB 1 is provided with an intermediate plate portion 14 in which the upper plate portion 11 is partially removed to form the female shape portion 200.
FIG. 2B shows a fitting structure of the center 7 of the part B in FIG. 1 to the CCB 1. In this case, the male part 100 is formed on the center 7 and the female part 200 is formed on the CCB 1, and the center 7 and the CCB 1 are pressed by pushing the center 7 as shown by arrows in the drawing. And male and female are fitted. Note that the CCB 1 is provided with an intermediate plate portion 14 in which the lower plate portion 12 is partially removed to form the female shape portion 200.
[0013]
FIG. 2C shows a structure in which the steering support bracket 5 of the portion C in FIG. 1 is fitted to the CCB 1. Also in this case, the male-shaped part 100 is formed on the steering support bracket 5 and the female-shaped part 200 is formed on the CCB1, and the steering support 5 and the CCB1 are pushed together as shown by arrows in the figure. Male and female are mated.
FIG. 2D shows a fitting structure of the side bracket 2 of the portion D in FIG. 1 to the CCB 1. Also in this case, the male-shaped part 100 is formed on the side bracket 2 and the female-shaped part 200 is formed on the CCB1, and the side bracket 2 and the CCB1 are male-female-fitted by being pushed in as indicated by arrows in the drawing. Are combined.
[0014]
FIG. 3 is an enlarged view showing a male and female fitting structure of the male shape part 100 and the female shape part 200. The male-shaped part 100 has two protruding parts 110 extending in parallel at an interval, and a claw part 120 protruding outward is formed near the tips of these protruding parts 110. The female shaped portion 200 has extensions 210 extending in parallel at a slightly wider interval than the two projections 110, and receives the claw 120 of the projection 110 near the base of these extensions 210. Receiving portion 220 is formed. Therefore, when the male-shaped part 100 is pushed into the female-shaped part 200, the protruding part 110 pushes into the extension part 210 and the claw part 120 enters into the claw receiving part 220, so that the two are firmly fitted together.

Therefore, when the male-shaped part 100 and the female-shaped part 200 are fitted, the fitting surfaces of the protruding part 110 and the extending part 210 are connected in an engaged state as shown in an enlarged cross section in FIG. . The depth and shape of these grooves 140 and 240 can be arbitrarily determined according to each condition. In this way, the fitting can be favorably performed by the fitting force or the frictional resistance due to the groove.
[0017]
FIG. 6 illustrates three combinations of a strength member and various members of the strength member structure for a vehicle according to the embodiment of the present invention. FIG. 6A shows a case where the CCB 1 and the air conditioning passage 8 having the air outlet 81 of the vehicle air conditioner are vertically combined. In this case, the fitting structure is such that the center 7 and the steering support bracket 5 are pushed into the CCB 1 arranged below from below. The two protrusions 110 of the male-shaped portion 100 of the side bracket 2 are provided in parallel in the lateral direction.
FIG. 6B shows a case where the CCB 1 and the air conditioning passage 8 having the air outlet 81 are combined in the lateral direction (left-right direction).

In this case, the CCB1 uses a strength member that is extruded and formed as a tubular body having a rectangular cross section, and the CCB1 has an outlet 81 opened. The center 7 is attached to the CCB 1 by male and female fitting, and the steering support bracket 5 has a fitting structure that is pushed in from below. The male shape portion 100 of the side bracket 2 has a shape that wraps the CCB 1 at four corners.
[0018]
FIG. 7 shows another embodiment of the automotive strength member structure of the present invention. In the present embodiment, an electronic control unit board (ECU board) 9 is incorporated in a hollow portion between the partition walls 13 of the CCB 1 made of an extruded aluminum block material. That is, as shown in the enlarged view of the portion E in FIG. In this way, the hollow portion of the strength member can be effectively used.
[0019]
FIG. 8 shows still another embodiment of the automotive strength member structure of the present invention. In the present embodiment, the CCB 1 is constituted by a combination of a plurality of extruded aluminum block materials 1A, 1B and 1C. Naturally, these block materials (1A, 1B, 1C) are also fitted together. In this embodiment, since the hollow portion of the central block 1A of the CCB 1 is used as the face duct passage 8a which is a part of the air conditioning passage 8, the block 1A is formed in a different shape from the other blocks 1B and 1C. . As shown in an exploded view of a portion F in FIG. 7, a heat insulating material 15 is lined in the face duct passage 8a of the central block 1A, and a casing portion of the vehicle air conditioner is provided in one of the face duct passages 8a. 82 is connected, and the other side is provided with a grill 83 for blowing out the face. The center block 7 is fitted and coupled to the center block 1A of the CCB 1 from below, and the airbag bracket 6 is coupled to the block 1B from above. The side bracket 2 is fitted to the block 1C from the side. Further, an air conditioning passage 8 having an air outlet 81 is disposed above the CCB 1 and is connected to a casing 82 of the vehicle air conditioner.
[0020]
In the present invention, a structure in which CCB1, which is a strength member for automobiles, and various members including various brackets attached to the CCB1 are basically basically combined using an extruded aluminum product, It is also possible to combine components of different materials by using molded products of a material such as resin for various members.
[0021]
Further, when the CCB 1 is configured by a combination of a plurality of block materials, for example, when it is desired to partially increase the strength of the strength member such as a steering attachment portion, the plate thickness and shape of the block material corresponding to the portion are required. Just by changing, it is possible to easily increase the partial strength.
Furthermore, even when the shape of the CCB 1 and the mounting posture of the parts are not uniform according to various vehicles, the shape of the CCB and the mounting structure of various members can be easily changed as shown in FIGS. Can be adjusted to
[0022]
As described above, according to the present invention, not only conventionally, the processing of the brackets is performed by press working, but also various members including the CCB as the strength member and the attached brackets can be easily processed by extrusion. In addition, since screwing and welding are not required for assembling various members to the CCB, the number of assembling steps can be reduced. In addition, after assembling each block material, another part can be added by welding or the like to increase the strength. Further, welding or the like may be added to the fitting portion to increase the strength.
