[0034] In a first aspect, please refer to Figure 1 and Figure 2 , an embodiment of this application provides a decorative shell 10. The decorative shell 10 includes a decorative panel 11 and a reinforcing boss 12. The decorative panel 11 has a decorative surface and a back surface that are oppositely arranged. The reinforcing boss 12 is provided on the back surface, and a first glue-stealing hole 121 is provided on the side of the reinforcing boss 12 close to the decorative panel 11.

[0035] It should be noted that the glue-stealing hole is formed by the glue-stealing process. The glue-stealing process is to adjust the structure of the mold during the mold manufacturing process, so that the plastic can form a thinner wall thickness in certain areas during the injection molding process, thereby achieving the purpose of reducing material usage, lowering costs, and improving production efficiency. It is mainly used to prevent the plastic finished product from being accidentally deformed due to thermal expansion and contraction during the cooling and forming stage, which may affect the appearance.

[0036] For the decorative shell 10 provided in this application, a reinforcing boss 12 is provided on the back surface of the decorative panel 11. The reinforcing boss 12 can play a role in structural reinforcement, effectively restricting the displacement between the decorative panel 11 and the middle frame 20, and preventing the decorative panel 11 from being indented inward to scratch the middle frame 20. In addition, a glue-stealing design is carried out on the reinforcing boss 12, which can prevent the appearance surface of the decorative panel 11 from shrinking and affecting the appearance beauty, and can reduce material usage, lower costs, and improve production efficiency.

[0037] In some embodiments, please refer to Figure 3 and Figure 4, the height H of the first glue-stealing hole 121 is 4.5 mm to 5.5 mm, for example, it can be 4.6 mm, 4.7 mm, 4.8 mm, 4.9 mm, 5.0 mm, 5.1 mm, 5.2 mm, 5.3 mm, 5.4 mm or the range between any two values, etc. It should be noted that the height H of the first glue-stealing hole 121 is the distance from the back side to the side far from the back side of the first glue-stealing hole 121.

[0038] In some embodiments, the wall thickness of the first glue-stealing hole 121 is 1 / 8 to 3 / 8 of the thickness of the decorative panel 11, for example, it can be 1 / 4. When the wall thickness of the first glue-stealing hole 121 is within this range, it can effectively prevent the decorative panel 11 from shrinking and affecting the appearance.

[0039] In some embodiments, a second glue-stealing hole 122 is provided on the side of the reinforcing boss 12 away from the decorative panel 11. Further, the extending direction of the second glue-stealing hole 122 is inclined or perpendicular to the extending direction of the first glue-stealing hole 121.

[0040] Exemplarily, the extending direction of the first glue-stealing hole 121 can be a direction parallel to the plane where the decorative panel 11 is located, and the extending direction of the second glue-stealing hole 122 can be a direction perpendicular to the plane where the decorative panel 11 is located. In other words, the second glue-stealing hole 122 can extend from the side close to the decorative panel 11 to the side far from the decorative panel 11.

[0041] In some embodiments, please continue to refer to Figure 3 , the thickness L of the second glue-stealing hole 122 is 1 / 4 to 3 / 4 of the thickness of the reinforcing boss 12, for example, it can be 1 / 2. It should be noted that the thickness L of the second glue-stealing hole 122 is the distance in its extending direction, that is, the distance in the direction perpendicular to the plane where the decorative panel 11 is located.

[0042] In some embodiments, there are multiple second glue-stealing holes 122, and the multiple second glue-stealing holes 122 are symmetrically distributed on the side of the reinforcing boss 12 away from the decorative panel 11.

[0043] Exemplarily, there are four second glue-stealing holes 122, and the four second glue-stealing holes 122 are distributed in a cross shape on the side of the reinforcing boss 12 away from the decorative panel 11.
