Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in further detail with reference to the accompanying drawings. Further, in the drawings herein, there are cases where the sizes of components are not uniform or some components are omitted for convenience of explanation.
As shown in fig. 2, the noise reduction reinforcing plate 10 of the top cover of the present invention is substantially rectangular, and mainly comprises a corrugated cardboard 1, a plurality of bonding portions 2, and a damping pad 3, and is mounted at the rear portion of the top cover 4 and below the top cover 4 by the plurality of bonding portions 2 as shown in fig. 1 and 3.
Specifically, the corrugated cardboard 1 is a double-corrugated cardboard, which is composed of 5 layers of moisture-proof and flame-retardant kraft paper, and has a thickness of 5-9mm and an areal density of 900-2And thus is lightweight. And as shown in fig. 4, has a large and small double W-shaped structure. Further, a depression into which a damper pad 3 described later is fitted is provided in a substantially middle portion of the corrugated cardboard 1, and the shape and area of the depression are the same as those of the damper pad 3 described later, and the depth is the same as the thickness of the damper pad 3 described later.
The adhesive portions 2 are foam double-sided tapes, and are unevenly distributed on one surface of the corrugated cardboard sheet 1 (in the illustrated example, extending in the longitudinal direction and arranged in the lateral direction) so as to extend in the lateral direction (corresponding to the vehicle width direction) or the longitudinal direction (corresponding to the vehicle body front-rear direction) of the corrugated cardboard sheet 1 and be arranged in the longitudinal direction or the lateral direction, and preferably have a thickness of 0.8 to 1.5mm and a width of 10 to 20mm, and the interval between the plurality of adhesive portions 2 is 100mm to 200 mm. In addition, it is preferable that the total area of the plurality of bonding portions 2 accounts for 8% to 15% of the surface area of the corrugated cardboard 1. If the number of the bonded portions 2 is too large, the cost increases; if the adhesive portion 2 is too small, the reinforcing effect cannot be achieved.
The damping pad 3 is, for example, a butyl damping pad, has a thickness of 1 to 3mm, and can be just embedded in the concave of the corrugated cardboard 1, so that the damping pad 3 does not protrude from the corrugated cardboard 1 when being embedded in the concave of the corrugated cardboard 1, and when the noise reduction reinforcing plate for roof cover 10 is attached to the roof cover 4 of the automobile, the plane of the connecting surface between the corrugated cardboard 1 and the roof cover 4 is ensured.
In this case, adhesive portions 2 that are continuous with the adhesive portions 2 extending over the surface of the corrugated cardboard 1 can be provided in the depressions of the corrugated cardboard 1 for fixing the damping mat 3 when it is inserted.
In the drawings, the damping pad has a pentagonal shape in which one corner of a square is slightly cut, and the cut portion can be set as a mounting direction mark when the damping pad is mounted on the top cover 4, thereby facilitating the mounting of the top cover noise reduction reinforcing plate 10.
The damping pad 3 has self-adhesiveness or high magnetic property, and when attached to the top cover, the damping pad 3 is fixed to the lower surface of the top cover 4 by the self-adhesiveness or high magnetic property.
Further, the damping pad 3 has damping performance, and noise generated from the top cover can be further reduced.
As shown in fig. 5, the half-cut lines (transverse half-cut line 5, longitudinal half-cut line 6) may be provided on the surface of the cardboard sheet 1 so as to extend in the longitudinal and transverse directions of the cardboard sheet 1. Through setting up half tangent line 5, 6, can make corrugated container board 1 form certain radian easily, when installing to top cap 4, can make corrugated container board 1 and the lower surface laminating of top cap 4 of automobile body better.
Further, the side of the corrugated cardboard sheet 1 provided with the adhesive portion 2 may be covered with a release paper (not shown), preferably a single-sided release paper, which serves to hold the adhesive portion 2 before assembly.
The structure of the noise reduction reinforcing plate 10 for a top cover of the present invention has been described above, but the present invention is not limited thereto. For example, the outer dimensions of the top noise reduction reinforcing plate 10 are not limited to the substantially rectangular shape, and may be determined by CAE analysis and real vehicle verification, and the distribution of the half-tangents may be designed according to the top shape or the like. The bonding portion is not limited to the double-sided foam adhesive tape, and may be a glass adhesive tape or the like as long as the corrugated cardboard 1 can be bonded and fixed to the top cover 4. In addition, the corrugated cardboard 1 is not limited to the double corrugated cardboard, and a single corrugated cardboard or other multi-ply corrugated cardboard may be appropriately selected. In addition, the damping pad can be omitted or made of other materials.
With the above structure, when the top cover noise reduction reinforcing plate 10 is assembled in the final assembly, the release paper is torn off and stuck according to the installation direction marks. Simultaneously, according to the radian of roof, with corrugated container board along horizontal vertical half tangent line bending for corrugated container board better laminating in top cap lower surface. In addition, in order to ensure the connection of the top cover noise reduction reinforcing plate and the top cover, pre-pressing is preferably performed at the position of each bonding portion. In addition, in order to ensure the consistency of the assembly positions, a special tool is preferably used.
According to the utility model discloses a reinforcing plate of making an uproar falls in top cap because corrugated container board has bursting strength and edge crush strength height, area density is low, waterproof not moisture absorption, fall make an uproar, fire-retardant, characteristics such as molding freedom, consequently, falls the reinforcing plate of making an uproar through at the top cap and adopts corrugated container board as the main material, can solve the top cap rigidity difference simultaneously and the noise problem to the quality is light, easy to process.
Further, the adhesive portion is fixed to the corrugated cardboard in advance in a self-adhesive manner and held by a release paper. On the other hand, tear off during assembly and paste on the top cap after the release paper, from this, can be fixed in the top cap with simple process with the reinforcing plate that makes an uproar that falls of top cap. The operation is simple and the cost is low.
Moreover, the damping pad is arranged, so that the noise reduction effect can be further improved.
While particular embodiments of the present invention have been described above, it will be understood by those skilled in the art that these are by way of example only and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments can be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications all fall within the scope of the present invention.
