[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for a pad material to be mounted in a vehicle, and more particularly to a mounting structure for a vehicle pad material capable of easily and accurately fixing the pad material.

[0002]

[Prior art]

 Conventionally, in order to prevent the sound or vibration of the driving part installed under the vehicle floor from being transmitted to the inside of the vehicle, a foamed pad material 27 is formed on the panel-like base material inside the vehicle, especially on the floor base material 21. Is attached. At this time, as shown in FIG. 4, the double-sided tape 28 is previously attached to the back surface of the pad material 27, and the release paper of the double-sided tape 28 is peeled off at the time of the attachment work to be fixed and attached at a predetermined position ( (See FIG. 5).

[0003]

[Problems to be solved by the device]

 However, there is a drawback in that the number of steps increases due to the work of attaching the double-sided tape 28 to the pad material 27 and the work of peeling off the release paper. Further, it is difficult to remove the double-sided tape 28 once it is attached. For this reason, careful positioning adjustment is required to attach the pad material 27 to the surface of the base material 21 formed with irregularities, which requires time and effort.

Therefore, it is an object of the present invention to provide a vehicle pad material mounting structure capable of easily and accurately attaching the pad material to a panel-shaped base material in a vehicle.

【Example】

 An embodiment of the present invention will be described below with reference to FIG. 1 and FIG. 3 for the panel-shaped base material 1 and the pad material 7. FIG. 1 is a perspective view showing a state in which the pad material 7 is attached to the floor base material 1. The floor base material 1 constitutes a part of the vehicle as in the conventional case, and serves as a floor material that separates the drive portion and the passenger space. Recesses 2 are formed on the floor base material 1 at regular intervals, and a plurality of pad materials 7 having vibration and soundproof effects are attached.

Of these mounting recesses 2, two stud bolts 3 are formed in an upright shape at a predetermined position of the recess 2 corresponding to one pad member 7 so as to be directed upward. The stud bolt 3 is formed of a flange-shaped head portion 4 and a short rod-shaped base portion 5, and the lower end of the base portion 5 is fixed to the floor base material 1. The shape of the head 4 is not particularly limited to a disc shape, but may be a conical shape or a spherical shape, for example. A screw groove 5a is formed on the outer periphery of the base 5 in the axial direction (see FIG. 2A). The method of attaching the stud bolt 3 to the floor base material 1 may be adhesive, welding, or screwing, and is not particularly limited.

As shown in FIG. 2, the pad material 7 made of a foam molding base material such as polyethylene is foam-molded into a three-dimensional shape that follows the shape of the mounting recess 2. A female member 8 is integrally molded at a predetermined position on the lower surface side of the pad material 7, that is, on the side corresponding to the surface of the pad material mounting recess 2 (see FIG. 3).

The female member 8 is formed into a substantially container shape having a recessed portion 8 a including an insertion portion 9 for opening the head portion 4 of the stud bolt 3 so that the head portion 4 can be inserted therein and a surrounding portion 10 in which the head portion 4 can be built. It is made of an elastic material such as resin and is elastically deformable as a whole. The insertion portion 9 has a diameter that allows the head 4 to be inserted by elastic deformation and a depth corresponding to the length of the shaft, and the surrounding portion 10 at the back has a diameter of the head 4. Since the space is larger than the above, a step 8b is formed as a result between the insertion portion 9 and the surrounding portion 10. The step 8b can lock the head 4 (see FIG. 2 (a)).

Further, as shown in FIG. 2B, two claws 11 are formed so as to project from the step 8b so as to face each other. The tip end side of the claw 11 is partially cut out to form a substantially bifurcated shape, and the notched inner crotch side can be engaged with the thread groove 5a of the base portion 5 of the stud bolt 3 described above. Further, the claw 11 can be elastically deformed like the female member 8.

The female member 8 as described above is integrally molded in an embedded shape when the pad material 7 is foam-molded so that the opening portion of the insertion portion 9 is located on the floor side surface of the pad material 7. As a result, the concave portion 8a is formed by the female member 8 on the floor base material 1 side of the pad material 7.

The effects of the structures of the floor base material 1 and the pad material 7 configured as described above in the work of attaching the pad material 7 will be described below. First, unlike the prior art, the structure for attaching the floor base material 1 is integrally formed on the pad material 7 itself. For this reason, it is not necessary to attach the double-sided tape to the pad material 7 as in the conventional case. Further, since the female member 8 is integrally formed with the pad material 7, it does not take time and effort to attach the female member 8 using an adhesive.

Then, the stud bolt 3 formed on the floor base material 1 side is covered with the female member 8 formed on the pad material 7 so that the pad material 7 is positioned and the pad material 7 is pressed down. By doing so, the pad material 7 can be attached accurately and in a short time without complicated positioning adjustment.

That is, when the female member 8 is applied to the stud bolt 3 and pressed down from above, the head 4 of the stud bolt 3 is inserted into the insertion portion 9 and abuts on the claw 11. 11 is elastically deformed, the head 4 reaches the surrounding portion 10 and is locked by the step 8b, and at the same time, the entire female member 8 covers the stud bolt 3 and the surface of the pad base 7 is the floor base 1. Reach the surface. On the other hand, the claw 11 is restored to its original position by its elasticity, and the tip side is locked and fixed in the screw groove 5a so as to sandwich the base portion 5 inserted in the insertion portion 9 from both sides.

As a result, the pad material 7 is positioned in close contact with the surface of the mounting recess 2 while closely following the surface of the mounting recess 2, and is fixed to the recess 2 at the same time. Therefore, the pad material 7 can absorb noise and vibration from the drive means under the floor base material 1 in the mounting recess 2 as in the conventional case. In addition, since it is always installed in an appropriate position, there is no failure or failure in installation, and it is possible to always obtain a certain soundproof and vibration-proof effect. Further, since the floor mat or the like is further laid on the pad material 7 being fixed, the surface of the floor base material 1 and the pad material 7 are surely brought into close contact with each other, and a soundproof effect or the like is exhibited.

Further, when removing the pad member 7, if the pad member 7 is moved left and right, up and down to elastically deform the female member 8, the claws 11 and the head 4 formed in the female member 8 will be elastic. The stud bolt 3 is deformed to release the engagement between the stud bolt 3 and the female member 8, and the pad material 7 can be separated from the floor base material 1. Therefore, unlike the conventional case, the back surface of the pad material 7 is not damaged by peeling of the double-sided tape, can be easily and cleanly attached and detached, and can be easily attached again.

In this way, the pad member 7 can be attached accurately and easily along the entire surface of the mounting recess 2 by the female member 8 and the stud bolt 3. In addition, it is more effective in terms of effect that the female member 8 and the stud bolt 3 themselves are formed of a material having a property of absorbing sound and vibration. Further, the present invention is not limited to the floor base material 1 and the pad material 7 in a vehicle, and the present example can be applied to the case where the foam-molded base material is attached and fixed using a double-sided tape.
