[0006] In the aforementioned combined car wall, the positioning seat is provided with a positioning hole whose radius increases continuously toward the opening direction, and a rubber pad is provided in the positioning hole.

[0007] In the aforementioned combined car wall, the second reinforcing ribs are staggered with the first reinforcing ribs.

[0008] In the aforementioned combined car wall, the outer car wall plate is provided with a mounting groove corresponding to the nut.

[0009] Compared with the prior art, the utility model arranges a positioning seat and a positioning block to make the positioning of the outer car wall panel and the first reinforcing rib faster and more convenient, and the first reinforcing rib and the second reinforcing rib are staggered, so that the first sound insulation sponge and the second sound insulation sponge are staggered, and the sound absorption effect is better.

DETAILED DESCRIPTION

[0013] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0014] Embodiment. A combined car wall is composed of Figure 1-2 As shown, it includes an inner car wall panel 1, wherein a plurality of first reinforcing ribs 2 are provided in the length direction of the inner car wall panel 1, a first sound insulation sponge 3 is provided between the first reinforcing ribs 2, a plurality of nuts 5 for connecting the outer car wall panel 4 are provided on the first reinforcing ribs 2, positioning seats 6 are provided on the upper and lower sides of the nuts 5, a positioning block 7 corresponding to the positioning seat 6 is provided on the rear side of the outer car wall panel 4, a second reinforcing rib 11 is provided inside the outer car wall panel 4, and a second sound insulation sponge 8 is provided between the second reinforcing ribs 11.

[0015] The positioning seat 6 is provided with a positioning hole 9 whose radius increases continuously toward the opening direction, and a rubber pad 10 is provided in the positioning hole 9 .

[0016] The second reinforcing rib 11 and the first reinforcing rib 2 are staggered in distribution.

[0017] The outer car wall plate 4 is provided with a mounting groove 12 corresponding to the nut 5 .

[0018] Principle of the utility model: The inner car wall panel 1 of the present application is provided with a bolt hole for fixing the first reinforcing rib 2. The first reinforcing rib 2 is fixed by the joint action of glue and bolts during installation, and then the first sound insulation sponge 3 is bonded between the first reinforcing ribs 2 with glue. The first reinforcing rib 2 is provided with a nut 5, which can be a flat-head rivet nut, and the outer car wall panel 4 can be connected to the first reinforcing rib 2 by bolts. The positioning block 7 is fixed to the rear side of the outer car wall panel 4 by welding. The position of the positioning block needs to be determined before welding. This can be done by customizing a template, in which a through hole corresponding to the position of the positioning block is provided, and the position of the positioning block 7 can be determined by tracing points. When the inner car wall panel 1 and the outer car wall panel 4 are connected, the outer car wall panel 4 and the first reinforcing rib 2 can be quickly positioned by the cooperation of the positioning seat 6 and the positioning block 7. The positioning seat 6 is provided with a positioning hole 9 with a radius that increases continuously in the opening direction, so that the positioning block 7 can slide into the positioning hole 9, and then the installation of the outer car wall panel 4 is completed by tightening the bolts. In addition, the arrangement of the positioning seat 6 and the positioning block 7 can increase the contact area between the outer car wall panel 4 and the inner car wall panel 1, making the operation more stable. The outer car wall panel 4 is provided with a second reinforcing rib 11 that is staggered with the first reinforcing rib 2. The second reinforcing rib 11 is installed through the fixing holes at the upper and lower ends of the front side of the outer car wall panel 4. The outer car wall panel 4 and the inner car wall panel 1 have relatively staggered positions of the fixing holes, and a second sound insulation sponge 8 is arranged between the second reinforcing rib 11. The first sound insulation sponge 3 and the second sound insulation sponge 8 are staggered, and the sound insulation effect is better. The second sound insulation sponge 8 or the first sound insulation sponge 3 can also be replaced with a sound insulation board to increase the weight of the car.
