detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Fig. 1 to Fig. 3, an embodiment of the present utility model, a kind of automobile pedal mounting structure, it comprises dash board 1, mounting bracket 2, sound insulation pad 3 and pedal 4, and described pedal 4 is connected on the described On the dash panel 1, the mounting bracket 2 is fixed on the dash panel 1, and the mounting bracket 2 includes two separate bracket members; the sound insulation pad 3 is arranged on the dash panel 1 and the dash panel 1. Between the pedals 4, the soundproof pad 3 is provided with an avoidance hole 31 for the mounting bracket 2 to be embedded without gap; the thickness of the soundproof pad 3 is greater than the height of the mounting bracket 2, and its thickness is preferably the 1.2 times the height of the bracket 2, when the pedal 4 is connected to the dash panel 1, the sound insulation pad 3 is pressed against the dash panel 1 by the pedal 4. When installing, first weld the mounting bracket 2 on the dash panel 1, then align the mounting bracket 2 with the avoidance hole 31 of the sound insulation pad 3 and insert it, so that the sound insulation pad 3 can be quickly fixed on the dash panel 1 Finally, the pedal 4 is connected to the dash panel 1 by bolts. At this time, it should be noted that the sound insulation pad 3 should be pressed by the pedal 4 to be in a compressed state. It can be seen that the utility model adds a separate mounting bracket 2 between the dash panel 1 and the pedal 4, and the sound insulation pad 3 is opened according to the shape of the pedal 4 bracket (that is, the avoidance hole 31), thereby reducing the noise insulation pad 3 to the greatest extent. The opening area ensures the coverage of the sound insulation pad 3; at the same time, since the thickness of the sound insulation pad 3 is greater than the height of the mounting bracket 2, the sound insulation pad 3 is compressed by connecting the pedal 4 with the dash panel 1, which improves the connection between the sound insulation pad 3 and the height of the mounting bracket 2. The degree of fit of the sheet metal of the dash panel 1 improves the sound insulation performance of the dash system.

In order to further reduce the opening area of the sound insulation pad 3, the two ends of the support member are respectively provided with first through holes 21; the dash panel 1 is provided with first mounting holes corresponding to the first through holes 21 11 ; the pedals 4 are respectively provided with second mounting holes 41 corresponding to the first through holes 21 . The pedal 4 is fixedly connected to the dash panel 1 through the first installation hole 11 , the first through hole 21 and the second installation hole 41 through bolts. In this way, the pre-set avoidance hole 31 for accommodating the mounting bracket 2 on the sound-insulating pad 3 is fully utilized, and there is no need to open holes in other areas of the sound-insulating pad 3, effectively reducing the opening settings of the sound-insulating pad 3, and further improving the sound insulation. Pad 3 coverage.

A reinforcing rib 22 is connected between the two first through holes 21 . When the mounting bracket 2 is welded on the dash panel 1 , the stiffening rib 22 can strengthen the compression resistance of the dash panel 1 .

According to the requirement of laying the sound insulation mat, the coverage area of the sound insulation mat 3 should be consistent with the area of the dash panel 1 . Thus, the area of the soundproof pad 3 must be greater than the contact area between the pedal 4 and the soundproof pad 3. When the pedal 4 pressed the soundproof pad 3, since the material of the soundproof pad 3 itself has elastic deformation characteristics, the pedal 4 and the soundproof pad 3 will be pressed into the sound insulation pad 3 to form a surrounding state (as shown in Figure 2), thereby further improving the fit between the sound insulation pad 3 located in the area of the pedal 4 and the dash panel 1, and further improving Improve the sound insulation performance of the front wall system.

Due to the functional requirements of the pedal 4, the dash panel 1, the sound insulation pad 3 and the pedal 4 are all provided with a second through hole 5 through which the resistance pump can pass.

The above disclosures are only preferred embodiments of the present utility model, and of course the scope of rights of the present utility model cannot be limited with this. Therefore, equivalent changes made according to the patent scope of the utility model are still covered by the utility model. scope.
