室Ｂ内に伝わり易くなつている。 By the way, in the darth lower panel 1,
Although it is necessary to fix the component mounting bracket 6 for supporting the brake pedal 5, the conventional component mounting portion has a structure as shown in the second figure. That is, the component mounting portion 4a of the inner panel 4 is attached to the outer panel 3.
is embossed toward the outer panel 3, and is superimposed on the component attachment portion 3a of the outer panel 3, so that both component attachment portions 3a, 4
Insert the threaded portion 8 of the weld bolt 8 into the hole 7 formed in a.
a and insert a cylindrical spacer 9 into the threaded portion 8a.
, and the component mounting bracket 6 is fixed to the dart lower panel 1 using nuts 10 (for example, Japanese Patent Laid-Open No. 53-30525). However, in such a component mounting structure, since the holes 7 are bored in both panels 3 and 4, rainwater etc. in the engine room A can easily enter the passenger compartment B through the holes 7, and the component mounting parts overlapped with each other. 3a and 4a where there is no Melseat 2, mechanical vibrations and heat in the engine compartment A are easily transmitted to the interior of the vehicle compartment B.

ることを提案するものである。 In view of the conventional parts mounting structure as described above, an object of the present invention is to obtain a structure in which damping material can be disposed throughout the entire sanderch panel without the need to drill a hole through it. A reinforcing bracket with a hat-shaped cross section is placed between the outer panel and the inner panel, the base of the reinforcing bracket is welded to the inner surface of the outer panel, and a part of the inner panel corresponding to the reinforcing bracket is inserted into the passenger compartment. An embossed part is formed to protrude inward, and the embossed part and the reinforcing bracket form a highly rigid closed cross-sectional structure, and the fastening member of the attached part is fixed to the upper side of the reinforcing bracket corresponding to the embossed part. This is what we propose to do.

を介装できる。 FIG. 3 is a sectional view corresponding to FIG. 2 showing a dart lower panel 1A according to the present invention, and the same structural parts as those in FIG. 2 are designated by the same reference numerals.
The illustrated embodiment is characterized by a hat-shaped reinforcing bracket 11 interposed between the outer panel 3 and the inner panel 4, and the inner panel 4 in which a portion corresponding to the reinforcing bracket 11 is embossed on the interior side of the vehicle. That is, both leg bases 11 of the reinforcing bracket 11
a and 11b are spot welded to the inner surface of the outer panel 3, and on the upper side 11c there is a head 8b of a weld bolt 8 for fastening the component mounting bracket 6.
However, the threaded portion 8a is inserted into the mounting hole 12 and welded in advance. The threaded portion 8b of the weld bolt 8 passes through the hole 13 of the inner panel 4, which is embossed in the opposite direction to the outer panel 3, into the passenger compartment B.
Since it is pulled out to the side, when the component mounting bracket 6 is fixed to the lower dashboard panel 1A using the cylindrical spacer 9 and nut 10, a highly rigid closed cross-sectional structure is created by the embossed part of the inner panel 4 and the reinforcing bracket 11. is obtained. Of course, for the Mel sheet 2 interposed between the outer panel 3 and the inner panel 4, there are slots 14 for receiving both leg bases 11a and 11b of the reinforcing bracket 11.
15, the outer panel 3
and Melsheet 2 over the entire inner panel 4.

ボルトに限定されることなく、ナツトでも良い。 In the illustrated embodiment, the present invention is applied to a dart lower panel, but the present invention can also be applied to other automotive sandwich panels. Further, the fastening member fixed to the reinforcing bracket 11 is not limited to the weld bolt of the above embodiment, but may also be a nut.

ある。 As is clear from the above description, according to the present invention, since holes are not drilled through the sanderch panel as in the conventional method, airtightness and liquidtightness can be maintained inside and outside the panel, and parts installation is possible. Since damping material can also be placed on the parts, sound insulation and heat insulation properties are further improved.Since the inner panel and the outer panel are connected with a reinforcing bracket, the input to the parts mounting part can also be applied to both the inner and outer panels. distributed in panels,
This also has the effect of improving the rigidity of the parts mounting section.
In addition, in the component mounting structure of the present invention, a highly rigid support portion with a closed cross section is formed by the embossed portion of the inner panel protruding toward the interior of the vehicle and the reinforcing bracket whose base is welded to the outer panel. This has the effect of making the installation condition very stable.
