Background
In recent years, automobiles are developed more and more rapidly, the control requirement on the comfort of the automobiles is more and more strict, and particularly, the NVH (noise, vibration and harshness) of new energy automobiles is more strict.
In the process of implementing the present invention, the inventor finds that the prior art has at least the following problems:
the scheme of making an uproar falls in current new forms of energy car cavity is the gluey piece of traditional skeleton style EVA inflation, and this type of structure volume is great, inconvenient installation during the use, and easy the dropout leads to the sound absorption effect of cavity unstable. The structural defects are as follows: the turnover and storage occupy large space; the framework type structural mould has high cost; the installation back easily drops, and the cavity can't guarantee to fill completely, and whole car NVH performance is difficult to guarantee.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a, the structure of making an uproar falls in the cavity of the new forms of energy car that does not drop in the use, and shortens the assemble duration and increase efficiency is provided.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a structure of making an uproar falls in cavity of new forms of energy car which characterized in that has:
the expansion film component is provided with a film mounting hole;
the first end of the assembling block is provided with a clamping pin, and the clamping pin is matched with the film mounting hole; the second end of the assembling block is provided with an assembling block mounting hole;
and the first end of the mounting buckle is matched with the mounting hole of the assembling block.
The expansion film component comprises a first expansion film, an interlayer aluminum plate and a second expansion film which are sequentially attached, wherein the interlayer aluminum plate is positioned between the first expansion film and the second expansion film.
The first end of installation buckle is equipped with the baffle, the baffle size is greater than the size of equipment piece mounting hole, the second end of buckle is the link.
And a vertical plate is arranged near the middle part of the assembling block and is attached to the surface of the expansion film component.
The expansion film component is at least provided with two groups of assembling blocks and mounting buckles.
One of the technical schemes has the advantages or beneficial effects that the structure is small in size, and the packaging and transportation cost is greatly reduced; and replacing the injection molding material with a sheet-shaped expansion material, clamping the buckle into the expansion film after the hole is formed in the new film, and assembling the buckle and the film in the cavity in a combined manner. This film structure goes out piece and uses the moulded die to replace traditional injection mould, not only reduces manufacturing cost, prevents slow-witted when the installation, and more importantly guarantees after the buckle aggregate erection that the part can not drop, has guaranteed the noise reduction effect that gives sound insulation of cavity, promotes whole car NVH.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1-4, a cavity noise reduction structure of a new energy vehicle is characterized by having:
the expansion film component is provided with a film mounting hole;
the first end of the assembling block is provided with a clamping pin, and the clamping pin is matched with the film mounting hole; the second end of the assembling block is provided with an assembling block mounting hole;
and the first end of the mounting buckle is matched with the mounting hole of the assembling block.
The expansion film component comprises a first expansion film, an interlayer aluminum plate and a second expansion film which are sequentially attached, wherein the interlayer aluminum plate is positioned between the first expansion film and the second expansion film.
The first end of installation buckle is equipped with the baffle, and the baffle size is greater than the size of equipment piece mounting hole, and the second end of buckle is the link.
The vertical plate is arranged near the middle part of the assembling block and is attached to the surface of the expansion film component.
The expansion film component is at least provided with two groups of assembling blocks and mounting buckles.
This structure of making an uproar falls in cavity is formed by EVA expansion film subassembly and PA66 buckle subassembly equipment, and EVA expansion film subassembly is formed by the punching press behind EVA expansion film and the laminating of intermediate layer aluminum plate, and PA66 buckle subassembly comprises equipment piece and assembly buckle joint. Firstly, clamping an assembly buckle into an assembly block mounting hole of an assembly block, and clamping the assembly buckle into the assembly block mounting hole of the assembly block; and then respectively clamping the mounting buckle of the assembly block into the film mounting hole of the EVA expansion film, and clamping the mounting buckle of the assembly block into the film mounting hole of the EVA expansion film. After the structure is assembled, the structure can be used in a welding workshop, and after the structure enters an electrophoresis process, the EVA expansion film can expand at high temperature, so that the filling of a cavity gap is realized.
One of the technical schemes has the advantages or beneficial effects that the structure is small in size, and the packaging and transportation cost is greatly reduced; and replacing the injection molding material with a sheet-shaped expansion material, clamping the buckle into the expansion film after the hole is formed in the new film, and assembling the buckle and the film in the cavity in a combined manner. This film structure goes out piece and uses the moulded die to replace traditional injection mould, not only reduces manufacturing cost, prevents slow-witted when the installation, and more importantly guarantees after the buckle aggregate erection that the part can not drop, has guaranteed the noise reduction effect that gives sound insulation of cavity, promotes whole car NVH.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
