Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to a mounting structure for an insulator/dutch which is attached to a dashboard panel surface in a vehicle interior.

《Prior art and its problems》 As is well known, in order to maintain quietness in the vehicle interior,
Various insulators are installed inside the car.

For example, as shown in Figure 4, the insulator
A darts 1 is attached on a darts panel 3 in front of the front seat so as not to transmit engine noise and vibrations from an engine room 2 into the vehicle interior.

The mounting structure of this insulator/dash will be explained based on FIGS. 5 and 6.

In FIG. 5, a bracket 4 made of iron plate is welded and fixed at an appropriate position on the dash panel 3. After this bracket 4 is inserted into the mounting hole 5 of the insulator dash 1, the tip of the bracket 4 is bent. As a result, the insulator/dash 1 is fixed on the surface of the dash panel 3.

Next, in FIG. 6, stud bolts 6 are welded and fixed at appropriate positions on the surface of the dash panel 3, and as in FIG.
After inserting the stud bolt 6 into the insulator dash 1, the resin clip 7 is fitted and fixed to the stud bolt 6 from the front side of the insulator dash 1, thereby placing the insulator dash 1 on the dash panel 3 surface. I'm trying to fix it.

However, in the case of the mounting structure using the bracket 4 shown in Fig. 5, the work of bending the bracket 4 is troublesome, and the edge portion of the bracket 4 is exposed, which leads to problems in terms of workability and safety. It was not desirable.

In addition, in the type that uses the clip 7 shown in Fig. 6, the tip of the stud bolt is hidden in the mounting hole 5 of the insulator/dutch 1 and is not exposed on the surface when the insulator/dash 1 is installed. Because the clip 7 is not attached, the work of installing the clip 7 becomes a blind work, and in addition, the clip 7 bites into the skin 1a of the insulator/dash 1.
Since smooth fitting and fixing cannot be achieved, there is a drawback that work efficiency is reduced.

<<Purpose of the invention>> This invention was made in view of the above-mentioned circumstances, and the purpose of this invention is to safely and smoothly perform the installation work when installing an insulator/dutch on the surface of the darts panel. This significantly improves work efficiency, and
It is an object of the present invention to provide a mounting structure for an insulator/dutch which achieves a good sealing effect.

《Structure and Effects of the Invention》 In order to achieve the above object, the present invention installs a stud bolt, which is installed upright on the interior side surface of the darts panel that separates the engine room and the passenger compartment, into the mounting hole of the insulator darts. The insulator/dutch around the mounting hole is crimped and held by the head flange by inserting the clip through the stud and engaging and fixing the leg of the clip consisting of a cylindrical leg and a head flange to the stud bolt. In the attachment structure of the dash, a sealing flange is provided around the cylindrical leg of the clip, and an embossed portion is recessed around the mounting hole of the insulator/dutch, so that the sealing flange can be , the embossed part of the insulator dash is sealed, and the head flange further seals the outer peripheral part of the insulator dash, so that it has a double sealing function.

That is, according to the above configuration, the stud bolts installed on the indoor side of the darts panel are inserted into the mounting holes of the insulator/dashboard and protrude into the embossed portions formed around the mounting holes. When attaching the clip, the person can visually see the stud bolt and attach the clip easily, and the sealing flange provided around the tip of the cylindrical leg of the clip presses and seals the embossed part. Therefore, the skin material of the insulator/dash will not get caught in the clip, and smooth installation work can be expected.

Furthermore, this clip has a head flange portion and a sealing flange portion that allow the insulator to be
Since the dowel mounting hole is double-sealed, the sealing performance is significantly improved, and this has the effect of greatly contributing to quietness in the vehicle interior.

<Description of Embodiments> Hereinafter, one embodiment of the insulator/dash mounting structure according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a sectional view illustrating the installed state of the insulator/dashion according to the present invention, Fig. 2 is a sectional view showing the insulator/dashion after installation, and Fig. 3 is a sectional view showing a modified example of the clip. It is.

In Fig. 1, insulator needle 1
0 is a sound absorbing layer 1 such as felt or urethane foam.
1 and a sound insulating skin layer 12 such as a PVC sheet or a rubber sheet, and is attached to the interior side of the dash panel 13.

Stud bolts 14 are erected and fixed at appropriate locations on the indoor side of the dash panel 13 by means such as welding, and the insulator darts 1 correspond to the locations where the stud bolts 14 are set.
A mounting hole 15 is provided on the 0 side.

Furthermore, in this application, this insulator
The embossed part 16 is located around the mounting hole 15 of the dash 10.
It is molded so that it is recessed.

On the other hand, the clip 17 that engages with the stud bolt 14 has a disk-shaped head flange portion 18,
A hollow cylindrical leg 19 protrudes from approximately the center of the head flange 18, and a hollow cylindrical leg 19.
9, and a sealing flange portion 20 provided around the tip of the sealing flange portion 2.
The outer peripheral edge 20a of the cylindrical leg 19 is bent downward, and a pair of locking claws 21 are formed protruding from the inner peripheral surface of the cylindrical leg 19.

Next, the insulator/dash 1 according to the present application
0 installation work will be explained in detail.

First, the insulator dash 10 is positioned on the dash panel 13 surface. At this time, if the stud bolt 14 erected on the surface of the dash panel 13 is inserted into the mounting hole 15 of the insulator dash 10, the tip of the stud bolt 14 is set to protrude into the embossed part 16. .

Therefore, when engaging the clip 17 with the stud bolt 14, the operator can visually check the position and protrusion amount of the stud bolt 14, and can easily perform the locking operation of the clip 17.

Then, the cylindrical leg portion 19 of the clip 17 may be fitted onto the outer periphery of the stud bolt 14 and fixed, but the skin layer 12 around the mounting hole 15 should be
6 is molded, and the sealing flange portion 20 of the clip 17 pushes the skin layer 12 outward, so the conventional problem of the skin layer 12 being caught is effectively solved, and the work of fitting the clip 17 is simplified. is carried out smoothly.

Furthermore, as shown in FIG. 2, when the clip 17 is attached, the cylindrical leg portion 19 of the clip 17
The locking pawl 21 provided on the inner circumference engages in the thread groove 14a of the stud bolt 14, and the stud bolt 1
4, the clip 17 is securely and firmly fixed to the insulator dash 10, and the upper surface of the insulator dash 10 is sealed by the seal flange 20 at the lower position of the clip 17 and the head flange 18 at the upper part. Therefore, this double sealing action can prevent noise from the engine room from propagating into the vehicle interior through the dash panel 13 and the mounting hole 15 as much as possible.

In the above embodiment, the outer circumferential edge 20a of the sealing flange portion 20 formed on the clip 17 is bent downward in order to provide a reliable sealing property. As shown, the sealing flange portion 20 may be formed into a curved shape to provide sealing properties through a spring effect.

Further, the shape of this sealing flange portion 20 is not limited to a disk shape, but may be formed into a rectangular shape.
may be provided on the outer peripheral surface of the cylindrical leg 19 instead of at the tip of the cylindrical leg 19.
