Detailed Description
It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be taken as limiting the scope of the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The invention is further described with reference to the following description and embodiments in conjunction with the accompanying drawings.
As shown in fig. 1 to 2, a matching structure of a front carpet assembly, a front floor and a console panel comprises a front carpet assembly 1, a front floor 2 and a console panel 3, wherein the front carpet assembly 1 comprises a plane portion 11 and a slope portion 12, the slope portion 12 of the front carpet assembly 1 is closely attached to a slope 22 of a central channel 21 of the front floor 2, the slope portion 12 of the front carpet assembly 1 comprises a PU (polyurethane) foam layer 121, an EPP (foamed polypropylene) foam layer 122 and a fabric layer 123 which are sequentially stacked from bottom to top, and a lower end of the console panel 3 is pressed against the slope portion 12 of the front carpet assembly 1.
The lower end of the sub dash panel 3 is provided with a bent portion 31 bent toward the center tunnel 21 of the front floor 2.
The lower edge of the bent portion 31 and the slope portion 12 of the front carpet assembly 1 are in a Y-direction (left-right direction of the vehicle) interference fit, i.e. horizontally facing the middle channel 21 direction of the front floor 2, preferably in a Y-direction interference fit of 3.0 mm.
The front carpet assembly 1 is embedded with an EPP at two sides of the matching area of the auxiliary instrument panel 3 to form an EPP foaming layer 122, and the problems of deformation and unevenness of the molded surface of the carpet caused by insufficient strength are solved due to high EPP compression strength and small compression permanent deformation.
In addition, EPP is foamed well in advance, and is pre-embedded into a PU foaming mould when PU of the carpet is foamed subsequently, so that the process defects of insufficient PU foaming density and insufficient foaming at the position are effectively overcome. Meanwhile, the EPP plays a good supporting role for the carpet, and the lower end edge of the auxiliary instrument board is interfered with the carpet in the Y direction by 3.0mm, so that the carpet is ensured to be matched with the auxiliary instrument board without leaving.
Since EPP density (22.5 kg/m) is much less than PU foaming (60 kg/m) when carrying out thin and long-term harvest, the weight of the carpet is effectively reduced. In addition, EPP belongs to compact foaming, and compared with PU loose-hole foaming, the sound insulation effect is achieved to a certain extent, and the NVH performance is improved to a certain extent.
The invention provides a matching structure of a front carpet assembly, a front floor and a sub-dashboard, which has the following improvements:
1. the front carpet assembly is embedded with an EPP foaming material at the middle channel, and the characteristics of high compression strength and small compression permanent deformation of the EPP foam are utilized to support the molded surface of the carpet, so that the problem that the carpet is easy to deform is solved, and the carpet is attached to the middle channel of the front floor;
2. the matching structure of the front carpet assembly and the auxiliary instrument panel is adjusted from fillet matching to the mode that the carpet inclined plane is in line contact with the edge of the auxiliary instrument panel, so that the problem of overlarge visual gap caused by fillet matching is solved, and the appearance perception quality is improved;
3. interference between the fabric layer of the front carpet assembly and the edge of the bottom of the auxiliary instrument panel is designed locally, so that parts are prevented from leaving empty after assembly;
4. EPP foaming density (22.5 kg/m) is lower than PU foaming density (60 kg/m) and is beneficial to weight reduction of the whole vehicle.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
