Background With the increasingly abundant appearance of housings of electronic devices such as mobile phones and flat panels, the housings made of glass, PU and the like are difficult to meet the requirements of consumers on the appearance of the mobile phones. The fiber composite material is gradually widely used in battery covers because of its high strength, light weight, and no shielding effect on antenna signals. However, the current shell made of fiber composite material has a single shape and a small design space. Disclosure of Invention The application provides a shell, electronic equipment and a preparation method of the shell, which can increase the design space of the appearance design of the shell. In order to achieve the above purpose, the application adopts the following technical scheme: The application provides a shell, which comprises a first material layer and a plurality of fiber composite layers stacked along a first direction, wherein the fiber composite layers comprise a first fiber composite layer and a second fiber composite layer which are sequentially connected along a second direction, the second direction is perpendicular to the first direction, the first fiber composite layer comprises a first fiber layer and a first polymer material attached to the first fiber layer, the second fiber composite layer comprises a second fiber layer and a second polymer material attached to the second fiber layer, the first material layer comprises a third polymer material, at least one layer of first fiber composite layer is connected with the first material layer, and the sum of the thicknesses of the first material layer and the first fiber composite layer is larger than that of the second fiber composite layer. Therefore, the thickness of the shell in the first fiber composite layer area is larger than that of the shell in the second fiber composite layer area, so that the appearance surface of the shell has different thicknesses, a three-dimensional appearance effect is achieved, diversification in modeling is achieved, and the design space of the appearance design of the shell is increased. In a possible implementation manner of the first aspect, the thickness of the third polymer material gradually decreases in a direction approaching the second fiber composite layer. Therefore, the appearance height difference of the shell is gradually changed, the curve transition effect on modeling can be achieved, and the design space of the shell is increased. Meanwhile, the thickness of the shell changes gradually, so that local stress concentration caused by thickness mutation can be avoided, and the overall structural strength of the shell is improved. In a possible implementation manner of the first aspect, the first material layer further includes a third fiber layer, the third polymer material is attached to the third fiber layer, and the third fiber layer and the first fiber composite layer are stacked. Therefore, the third fiber layers and the third polymer material layers attached to the third fiber layers can be added between the first fiber composite layers in multiple layers, so that the thickness of the shell in the first fiber composite layer area is larger than that of the shell in the second fiber composite layer area, namely, the appearance surface of the shell can have different thicknesses, the three-dimensional appearance effect can be displayed, the diversification of modeling is realized, and the design space of the appearance design of the shell is increased. In a possible implementation manner of the first aspect, when the first material layer further includes a third fiber layer, the third fiber layer is a plurality of layers, and the number of layers of the third fiber layer gradually decreases in a direction approaching the second fiber composite layer. Therefore, the thickness of the shell is gradually changed, a curve transition effect on modeling can be achieved, and the design space of the shell is increased. In one possible implementation of the first aspect, the first material layer is arranged between two adjacent first fiber composite layers. Therefore, a first material layer can be added between two adjacent first fiber composite layers in the preparation process, so that the thickness of the shell in the first fiber composite layer area is uniformly increased, and the uniformity of the structural strength of the shell is ensured. In one possible implementation of the first aspect, the first material layer is arranged on one side of the first fibre composite layer in the first direction. In this way, a first material layer may be added between two adjacent first fiber composite layers during the manufacturing process to increase the thickness of t
