[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 5 A plate for lightweight automobile interior parts, comprising a bottom plate 4 and a top plate 1 arranged parallel to the bottom plate 4, such as Figure 1 and Figure 4 As shown, the top plate 1 and the bottom plate 4 both include an outer layer 5, a middle layer 6, and an inner layer 7. The inner layer 7 is arranged close to the first support member 2. The inner layer 7 and the outer layer 5 are both aluminum alloy plates, and the middle layer 6 is a hard polyurethane foam plate. The aluminum alloy plate reduces the weight while ensuring the hardness of the top plate 1 and the bottom plate 4, and the hard polyurethane foam plate improves the sound insulation effect of the plate.

[0025] like Figure 2 and Figure 3 As shown, there is a gap between the top plate 1 and the bottom plate 4, and a plurality of first support members 2 and a plurality of second support members 3 are arranged in the gap, the upper and lower ends of the first support member 2 are connected to the top plate 1 and the bottom plate 4 respectively, and the upper and lower ends of the second support member 3 are connected to the top plate 1 and the bottom plate 4 respectively (that is, the first support member 2 and the second support member 3 are fixed to the inner layer 7), the first support member 2 and the second support member 3 are arranged one by one in a staggered manner and arranged along the length direction of the top plate 1, and the first support member 2 and the second support member 3 are fixedly connected; the first support member 2 and the second support member 3 are both support plates with wavy cross sections, and the first support member 2 and the second support member 3 are fixedly connected to each other; 2 is arranged perpendicularly to the axis of the second support member 3, wherein the first support member 2 and the second support member 3 each include a plurality of arc-shaped strip plates 8, the concave surfaces of adjacent strip plates 8 are arranged opposite to each other, and the strip plates 8 are connected end to end. In actual use, adjacent strip plates 8 are welded to form a continuous arch shape of the strip plates 8, that is, an arched support surface is formed between the top plate 1 and the bottom plate 4. When the top plate 1 and the bottom plate 4 are subjected to force, the support member will provide stress support for the top plate 1 and the bottom plate 4, so that the pressure exerted on the top plate 1 and the bottom plate 4 is dispersed through the arched structure of the support member, thereby improving the force strength of the plate.

[0026] Specifically, a continuous wavy support member is placed between the bottom plate 4 and the top plate 1, replacing the solid structure of the original plate, which can reduce the overall weight of the plate and achieve lightweighting of the plate. The staggered first support member 2 and the second support member 3 are distributed vertically and horizontally between the top plate 1 and the bottom plate 4 to avoid the support members being arranged in the same direction on the top plate 1 and the bottom plate 4, resulting in a larger hollow gap between the top plate 1 and the bottom plate 4, so that when the top plate 1 or the bottom plate 4 is subjected to force, only the top plate 1 or the bottom plate 4 is subjected to force, and the top plate 1 and the bottom plate 4 themselves have limited thickness and are prone to bending and breaking after being subjected to force. Therefore, the first support member 2 and the second support member 3 are staggered vertically and horizontally arranged, reducing the size of the hollow gap between the top plate 1 and the bottom plate 4, so that the top plate 1 and the bottom plate 4 have a fulcrum for force transmission and dispersion after being subjected to force, thereby effectively improving the force strength of the plate.

[0027] Further, such as Figure 5 As shown, a plurality of spaced reinforcing ribs 9 are provided on the surface of the strip plate 8, and the reinforcing ribs 9 are provided along the axial direction of the strip plate 8, thereby improving the stress-bearing strength of the strip plate 8 and thus improving the stress-bearing strength of the plate.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
