Description
Technical Field
The utility model relates to the field of manufacturing of vehicle body sheet metal sound insulation parts, in particular to a sheet metal opening-free sound insulation support connecting structure.
Background
In the running of an automobile, a lot of noise is generated on the road surface, and a soundproof rubber block is added to a lower Body of a White Body (Body in White refers to a Body which is not yet coated after the welding) to perform soundproof and noise reduction. In order to improve the soundproof performance, it is necessary to dispose the soundproof rubber block at a lower position. At present, the sound insulation support generally adopts a clamping mode, but holes are formed in a metal plate, the cavity is sealed by foaming glue after foaming, the foaming glue flows with uncertainty, the sealing stability of the hole is poor, when a vehicle is subjected to wading experiments, the sealing failure is easily caused by overlarge water pressure at the holes of the metal plate, the wading stability cannot be ensured, and the failure is often caused. In order to solve the problem of wading failure, a connection structure without sheet metal opening is urgently needed.
Disclosure of Invention
The utility model aims to provide a metal plate perforating-free sound insulation support connecting structure, which solves the problems that a metal plate needs to be perforated and welded with studs during installation of the existing sound insulation support, the stability of the involved water is poor, the cost is high and the like. According to the connecting structure, the sound insulation support can be installed under the condition that the metal plate is not perforated, water is isolated outside the metal plate, and the wading sealing stability of the vehicle is greatly improved.
The above object of the present utility model is achieved by the following technical solutions:
The metal plate opening-free sound insulation support connecting structure is characterized in that a nylon support 5 is arranged in the inner space of a lower reinforcing plate 3 of a column A of a vehicle body, the shape of the nylon support is matched with that of the lower reinforcing plate 3 of the column A of the vehicle body, a first foaming material 1 is connected with the nylon support 5 through a connecting column 2, and a second foaming material 4 is connected with the nylon support 5 through the connecting column 2; the nylon bracket 5 is provided with holes for inserting 2 bolt structures, and is fixedly connected with the lower inner plate 8 of the A column in a threaded manner through the first bolt 6 and the second bolt 7.
The foaming materials I and II are EVA foaming materials.
The nylon bracket 5 is a PA66 nylon bracket.
The utility model has the beneficial effects that: the novel design, simple structure does not need the panel beating trompil both can realize the installation of sound insulation piece and panel beating, has greatly improved vehicle sealing stability that wades. Convenient use and low cost. The practicability is strong.
