[0004] This utility model provides a sheet metal replacement for vehicle-mounted electrical appliances. The composite board is used in vehicle-mounted appliances, such as vehicle refrigerators and air conditioners, to replace the sheet metal used in existing vehicle-mounted appliance inner or outer casings. The composite board comprises a flame-retardant aluminum foil layer and a flame-retardant cardboard layer, which are bonded and pressed together via a flame-retardant adhesive layer to form the composite board. The cardboard surface of the composite board is bonded to the mounting location via a foam adhesive layer.

[0005] Preferably, the aluminum foil surface of the composite plate is embossed to form an embossed surface.

[0006] Preferably, the foamed rubber layer is a flame retardant and heat insulating foamed rubber layer.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] This utility model proposes a composite sheet metal replacement for vehicle-mounted electrical appliances. It is used in vehicle-mounted appliances, such as vehicle refrigerators and air conditioners, to replace the sheet metal used in existing vehicle appliance inner or outer casings. The composite sheet includes a flame-retardant aluminum foil layer and a flame-retardant cardboard layer, which are bonded and pressed together with a flame-retardant adhesive layer to form a flame-retardant composite sheet, providing both flame retardancy and heat insulation.

[0009] The flame-retardant aluminum foil layer provides the composite board with metallic texture and appearance, the flame-retardant cardboard layer provides the composite board with hardness and thickness, and the cardboard surface of the composite board is bonded to the installation position through the foam layer. After the foam layer hardens, it can further increase the hardness of the composite board, making the composite board meet the requirements of the vehicle electrical housing, and is lighter and has a lower production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a schematic structural diagram of a sheet metal thin plate replacement component for vehicle-mounted electrical appliances according to an embodiment of the present utility model.

[0011] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0012] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout identify the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0014] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0015] Reference Figure 1The embodiment of the present utility model provides a sheet metal thin plate replacement for vehicle-mounted electrical appliances, which is a composite plate used in vehicle-mounted electrical appliances, such as vehicle-mounted refrigerators, vehicle-mounted air conditioners, etc., to replace the sheet metal thin plates used in the inner shell or outer shell of vehicle-mounted electrical appliances in the prior art. The composite plate includes a flame-retardant aluminum foil layer 1 and a flame-retardant cardboard layer 2. The flame-retardant aluminum foil layer 1 and the flame-retardant cardboard layer 2 are bonded and pressed together by a flame-retardant adhesive layer 3 to form a composite plate, which has flame-retardant and heat-insulating effects. The lower surface of the flame-retardant cardboard layer 2 on the composite plate is the cardboard surface of the composite plate, and the upper surface of the flame-retardant aluminum foil layer 1 on the composite plate is the cardboard surface of the composite plate. The flame-retardant aluminum foil layer 1 provides the composite plate with a metallic texture and a metallic appearance, and the flame-retardant cardboard layer 2 provides the composite plate with hardness and thickness. The cardboard surface of the composite plate is bonded to the installation position 5 by a foam layer 4. After the foam layer 4 hardens, it can further increase the hardness of the composite plate, so that the composite plate meets the requirements of the vehicle-mounted electrical appliance housing, and is more lightweight and has a lower production cost.

[0016] The foamed rubber layer 4 is a flame retardant and heat insulating foamed rubber layer, which further improves the flame retardant and heat insulating properties of the composite board.

[0017] The aluminum foil surface of the composite board is embossed to create a textured surface. This process further bonds the flame-retardant aluminum foil layer to the flame-retardant paperboard layer. This embossed surface enhances the decorative qualities of the composite board, while the aluminum oxide film formed on the surface prevents further oxidation, forming a natural protective film and extending its service life.

[0018] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments. Based on these embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope to be protected by the present invention. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in this field can still combine, add, delete or make other adjustments to the features in the various embodiments of the present invention according to the circumstances without conflict, without making any creative work, so as to obtain different other technical solutions that do not deviate from the concept of the present invention in essence, and these technical solutions also fall within the scope to be protected by the present invention.
