Description

Panel, interior part and car

Technical Field

The utility model relates to a panel, interior trim part and car.

Background

For panels of interior trim systems, the panel is typically mounted to a base frame. As shown in fig. 1 and 2, for example, in a door module, if a panel 10 formed by injection molding of rigid plastic is attached to a sheet metal member as a base 30 via a skirt portion 20 thereof, vibration is likely to occur due to unevenness of a road surface or the like during vehicle running, and as shown in a region B of fig. 2, a hard contact collision occurs between the skirt portion 20 of the panel 10 and the base 30, which causes noise during vehicle running to affect the experience of a person in the vehicle, and also causes fatigue life of the panel 10 and the base 30 to be affected by alternating vibration load.

In this regard, as shown in fig. 3 and 4, a conventional solution is to provide a felt strip 40 or a foam strip between the skirt portion 20 and the base 30 so as to be spaced apart from each other, and to cushion the vibration between the skirt portion 20 and the base 30 with the felt strip 40 or the foam strip.

However, in the above method, the inventor found in long-term practice that, since the gap between the skirt portion 20 and the base 30 is small and the edge of the panel body has a curved shape, the felt or foam strip is difficult to be adhered to the skirt portion, which results in a complicated manufacturing process, and a space where the felt or foam strip is partially separated from the panel cover is also present, which affects the overall appearance of the interior trim component.

Additionally, reference numerals and/or letters may be repeated among the various examples throughout this disclosure. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

In addition, it is to be understood that references to "one embodiment", "an embodiment", and/or "some embodiments" mean that a particular feature, structure, or characteristic described in connection with at least one embodiment of the application is included. Therefore, it is emphasized and should be appreciated that two or more references to "an embodiment" or "one embodiment" or "an alternative embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, some features, structures, or characteristics of one or more embodiments of the present application may be combined as appropriate.

The panel of the embodiments described below may be provided in an interior part, such as a door panel assembly provided in an interior system of an automobile, or an interior part such as an instrument panel assembly. The following embodiments are described taking the door panel assembly as an example, but not limited thereto.

Referring to fig. 5 to 8, in one or more embodiments, the panel 1 includes a panel body 2 and a skirt portion 3, the skirt portion 3 is used for being connected with a base 4 for mounting the panel, and the base 4 is a sheet metal part, but not limited thereto. The skirt part 3 is arranged at the edge of the panel body 1 and is in contact with the base 4 to buffer the vibration of the panel body 1 and the base 4; the panel body 2 and the skirt portion 3 are one piece. The panel main body 2 and the skirt edge part 3 with the buffering function are integrated, so that the vibration between the panel 1 and the base 4 is reduced, the noise caused in the process is reduced, and the experience of passengers in the vehicle is optimized; meanwhile, the processing technology of subsequent interior parts such as the vehicle door panel assembly is simplified, and the processing cost is reduced. Specifically, the panel body 2 is made of a hard material, and the skirt portion 3 is made of a soft material, and vibration is damped by contact between the soft material and the base 4.

Further, in some embodiments, the hard material may be a hard injection molding material, such as ABS plastic (Acrylonitrile Butadiene Styrene plastic), PPMD15-20 (15% -20% talc modified polypropylene (PP) plastic), and the soft material may be a soft injection molding material, such as EPDM (Ethylene Propylene Diene Monomer), TPE (Thermoplastic Elastomer), and the like. Correspondingly, the molding method of the panel 1 is obtained by secondary injection molding. Referring to fig. 6 to 8, as shown in fig. 6, the secondary injection molding apparatus includes a mold cavity 5, a mold core 6 and a slider 7, wherein a hard injection material 8 is injected into the mold cavity 5 for the first injection to perform injection molding of the panel body 2, and then the slider is moved away to provide an injection space for the second injection, and a soft injection material 9 is injected into the injection space to form the skirt portion 3 with a function of buffering vibration of the panel and the base, so that the panel body 2 made of the hard material and the skirt portion 3 made of the soft material are subjected to the secondary injection molding, so that the panel body 2 and the skirt portion 3 are an integral piece.

With continued reference to fig. 5, in one or more embodiments, an example of a specific structure of the panel body 2 may be that the panel body 2 includes a main body surface 21 and a transition section 22, and the main body surface 21 and the transition section 22 are an integral piece. The transition section 22 is located at the edge of the panel body and extends from the edge of the main body surface 21 along a first direction L, and the first direction L is a direction away from the plane where the edge of the main body surface 21 is located; the skirt portion 3 extends from an end 221 of said transition section 22 remote from the body surface 21. As can be seen from the above description of the secondary injection molding process of the panel 1, the transition section 22 and the main body surface 21 are integrally formed in the primary injection molding process to form the integrated panel body 2, and the skirt portion 3 is secondarily injection molded on the basis of the transition section 22, so that the skirt portion 3 and the panel body 2 are integrally formed to form the panel 1. It will be understood by those skilled in the art that the number of times of injection molding of the panel body and the skirt portion is not limited to the above-disclosed two-shot molding process, but may be more, for example, it may be necessary to inject different soft injection molding materials in the extending direction of the skirt portion.

With continued reference to fig. 5, in some embodiments, the skirt portion 3 may also be configured such that the skirt portion 3 extends in the first direction L from an end of the transition section 22 remote from the body surface 21. The beneficial effect of this arrangement is that the overall look and feel of the panel 1 is further improved. The reason is that, for example, in the secondary injection molding process, because the skirt portion 3 and the panel main body 2 may have a seam when integrally processed, because the skirt portion 3 is made of a soft injection molding material different from the hard injection molding material used for the panel main body 2, a seam may occur at a boundary therebetween, and the skirt portion 3 also extends in the first direction L, so that the panel main body 2 can cover the seam that may occur, and the appearance of the interior part is ensured. The skirt portion 3 may have an extension length of about 2mm, which facilitates processing and ensures good cushioning properties and a good appearance of the interior trim part.

In summary, the panel, the interior part and the automobile adopting the embodiment have the advantages that the skirt edge part which has a buffering effect and is integrated with the panel main body is arranged, so that the processing technology of the panel and the interior part is simplified, the vibration between the panel and the base body is reduced, the noise caused by the vibration in the driving process of the automobile is reduced when the panel, the interior part and the automobile are applied to the automobile, and the riding experience of people in the automobile is optimized; meanwhile, the skirt edge part and the panel main body are integrated, so that the influence on the overall appearance of the interior trim part due to local separation caused by the adoption of the felt strip or the foam strip is avoided, and the riding experience of personnel in an automobile is improved.

Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention.
