Detailed Description

In order to make the objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. Several embodiments of the invention are given in the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical," "horizontal," "left," "right," "up," "down," and the like are for illustrative purposes only and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, a first embodiment of the present invention provides a decorative board, which includes a hard layer 2 and a covering layer 1, wherein the hard layer 2 is a conventional hard plastic part, and the covering layer 1 is a conventional flexible covering part.

Specifically, the coating layer 1 is made of a flexible material, the coating layer 1 covers the hard layer 2, a plurality of sequentially arranged convex ribs 3 are arranged between the coating layer 1 and the hard layer 2, and the convex ribs 3 and the hard layer 2 are integrally formed, in this embodiment, integrally injection-molded;

in addition, the cross section of the convex rib 3 is triangular, the triangular tip of the cross section of the convex rib 3 is in contact with the coating layer 1, and the convex ribs 3 are separated from each other.

The utility model has the advantages that:

firstly, the convex ribs 3 are utilized to greatly reduce the contact area between the hard layer 2 and the coating layer 1, reduce the friction force between the hard layer and the coating layer, and reduce the abnormal sound;

secondly, the cross section of the convex rib 3 is triangular, and the contact area between the cross section and the coating layer 1 is smaller than that between the cross sections in other shapes;

finally, mutual separation between the convex ribs 3 can prevent the convex ribs 3 from being damaged due to mutual extrusion when deforming, and the service life of the convex ribs 3 is prolonged.

In this embodiment, the thickness of the ribs 3 is 5mm, the distance between the ribs 3 is 5mm, and the internal angle of the triangular tip of the cross section of the ribs 3 is 60 degrees. In other embodiments, the thickness of the ribs 3 can be any value of 5-10 mm according to practical conditions, the distance between the ribs 3 can be any value of 2-20 mm, and the internal angle of the triangular tip of the cross section of the rib 3 can be any value of 10-120 degrees.

It should be noted that, the thicker the rib 3, the thicker the decorative plate, the larger the occupied space, the smaller the triangular tip of the cross section of the rib 3, the smaller the contact area between the cladding 1 and the rib 3, and the smaller the contact area when the cladding 1 deforms.

In this embodiment, the rib 3 is a long strip structure, which is convenient for injection molding with the hard layer 2. In other embodiments, the 3 sheets of the ribs can be in a cone-shaped structure, but the long-strip-shaped structure is adopted, so that the production is easier, and the production cost is saved.

Preferably, the rib 3 is a hollow structure, and the rib 3 and the hard layer 2 form a cavity.

It can be understood that the convex rib 3 is of a hollow structure, so that the whole weight of the decorative plate can be reduced, and the whole vehicle is light.

In addition, the cavity is filled with filler 31, and the density of the filler 31 is smaller than that of the convex rib 3.

It should be noted that, the rib 3 may be made of the same plastic material as the hard layer 2, and when the rib 3 is of a hollow structure, the strength of the rib 3 is inevitably reduced, and the filler 31 is disposed in the rib 3 to improve the strength of the rib 3. Wherein, the filler 31 can select the plastics that intensity reduces, density are lower, realizes the support to 3 inner walls of protruding muscle, improves the intensity of protruding muscle 3, reduces the whole weight of decorative board simultaneously.

Preferably, a plurality of protrusions 11 are uniformly arranged on the surface of the coating layer 1 away from the hard layer 2, and the protrusions 11 are of a spherical structure.

It should be noted that when the coating layer 1 is pressed, the spherical protrusions 11 can disperse the pressure, so that the point pressure becomes the surface pressure, the pressure applied to the ribs 3 is reduced, and the service life of the ribs 3 is prolonged.

A second embodiment of the present invention provides an automobile, which comprises at least a decorative panel of the first embodiment.

In the description herein, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
