An upper skirt plate structure comprises a top plate 1 and a base 2 attached to the top plate 1, wherein the top plate and the base are both of composite material pultrusion structures; the top plate 1 comprises a smooth plate body 11 and a bent plate body 12 positioned on the inner side of the smooth plate body 11, and a first cavity 13 is formed between the bent plate body 12 and the smooth plate body 11; the base 2 comprises a bottom plate 21, a connecting plate 22 connected to the bent plate 12, and at least one supporting plate 23, wherein a second cavity 24 is formed between the supporting plate 23 and the bottom plate 21 and the connecting plate 22.
As shown in figure 1, the top plate 1 forms the outer contour of the vehicle body, and the bent plate body 12 realizes the reinforcing function of the smooth plate body 11 while realizing the installation of the base 2, thereby ensuring the rigidity requirement of the structure. The bottom plate 21 in the base 2 is used for mounting the whole upper skirt structure, wherein the second cavity 24 formed by the support plate 23 effectively reinforces the strength of the whole base 2.
The bent plate body 12 includes a flat plate 12a and side plates 12b located at two sides of the flat plate 12a, and an included angle between the flat plate 12a and the side plates 12b is greater than or equal to 90 °. In fig. 2, a bent plate body 12 is shown, and as an optimization, as shown in fig. 3, it is preferable that the side plates 12b on both sides are symmetrically arranged, so that the first cavity 13 forms an isosceles trapezoid or an approximate isosceles trapezoid, wherein the selection of the two trapezoids depends on whether the inside of the smooth plate body 11 is in a plane structure. Dull and stereotyped 12 a's setting for base 2's installation is more convenient, and carries out better laminating with base 2 more easily, and the angle set up between dull and stereotyped 12a and the curb plate 12b mainly from the technology angle, and bigger angle can make the pultrusion quality obtain promoting.
In order to improve the strength of the top plate 1, at least one reinforcing rib 14 is arranged in the first cavity 13, and the reinforcing rib 14 connects the smooth plate body 11 and the flat plate 12 a. With continued reference to fig. 3, the first cavity 13 is further reinforced by the arrangement of the reinforcing rib 14, so that the area of the flat plate 12a can be further increased, and the installation of the base 2 is more convenient.
As a preference of the above embodiment, one end of the support plate 23 is connected to the middle or edge of the connection plate 22, and the other end of the support plate 23 is connected to the middle or edge of the bottom plate 21. As shown in fig. 4, a backup pad 23 one end and connecting plate 22 middle part connection have been demonstrated, the form of the other end and bottom plate 21 edge connection, as shown in fig. 5, a backup pad 23 one end and connecting plate 22 edge connection have been demonstrated, the form of the other end and bottom plate 21 edge connection, as shown in fig. 6, two backup pad 23 one ends have all been in bottom plate 21 edge connection, the form that the other end all is connected with the different positions in middle part of connecting plate 22, thereby form two second cavities 24, of course two second cavities 24's cross-sectional form is different, other combination forms do not show here, but all are in the utility model discloses a protection range. Wherein, the convex edge formed when the supporting plate 23 is connected with the middle part of the connecting plate 22 or the bottom plate 21 is used for fixing the connecting piece, which is more convenient and easy. Wherein the pultrusion process can be optimized in the form of a chamfer when two or more support plates 23 are provided with a sharp corner at their ends, as shown in the lower right hand corner in figure 6.
As an optimized form of the bottom plate 21, the bottom plate 21 comprises two parts arranged at an obtuse angle, one of which is connected to the connecting plate 22. With continued reference to fig. 4 and 5, by providing the bottom plate 21 in two parts, a smoother transition pattern more suitable for pultrusion can be formed after the connection of the connecting plates 22, the occurrence of sharp corner positions can be avoided, and the pultrusion quality can be ensured.
As a preference of the above embodiment, in order to further increase the strength of the entire upper skirt structure, the connecting plate 22 has a bent section 22a, so as to form the third cavity 3 with the bent plate body 12. As shown in fig. 7 and 8, the rigidity of the contact area between the top plate 1 and the base plate 2 is effectively enhanced by the formation of the third cavity 3.
Because above-mentioned roof 1 and base 2 are combined material's integral structure, at the in-process of connecting the two, the connecting piece need reach the hookup location through corresponding cavity, because the narrowness nature of position for the operation degree of difficulty increases, in order to solve above-mentioned problem, is provided with notch 21a on the bottom plate 21. As shown in fig. 9, by providing the notch 21a, a mounting position can be provided, so that the connecting plate 22 and the bent plate body 12 can be connected to the connecting position more conveniently and accurately by using a structure such as a rivet, and the operation of the rivet gun is facilitated, thereby reducing the difficulty of assembly.
Fig. 10 shows a schematic view of the installation of the base 2 relative to the top plate 1, wherein the length of the base 2 in the pultrusion direction and the number of the base 2 arranged relative to each top plate 1 can be selected according to actual needs. The installation position of the whole upper skirt plate structure can be adjusted more conveniently by arranging the waist-shaped holes on the bottom plate 21.
It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
