AI Technical Summary
The plastic shell of existing tablets requires a built-in metal roll cage in equipment over 10 inches, resulting in increased overall weight, complicated process and increased costs.
Using modified plastic injection molding technology, the shell is made of PPS+CF composite material or PC+ABS+30% GF composite material, and a grid-like reinforcement is formed on the inside of the shell to replace the traditional built-in roll cage design.
This achieves stronger rigidity and toughness of the shell, while reducing weight and manufacturing costs to meet application requirements.

Abstract
Description
Technical Field
[0001] The utility model relates to a tablet computer, in particular to a plastic shell of the tablet computer. Background Art
[0002] Tablet computers need to use front and back shells to support, fix and protect the screen. The front and back shells of existing tablet computers are both plastic shells. For tablet computers larger than 10 inches, a metal roll cage must be installed in the plastic shell by fixing or secondary injection molding. For related structures, please refer to Figure 1 The roll cage 100 is a mechanical reinforcement component, which is a plate-like or sheet-like structure. The roll cage 100 is combined with the injection-molded shell 101 by secondary injection molding or later assembly. Although this component can improve the overall strength of the tablet computer, it will increase the weight of the tablet computer, complicate the process and increase the cost, so improvements are needed. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a tablet computer plastic shell with stronger rigidity and toughness, lighter weight and lower manufacturing cost in view of the deficiencies of the prior art.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions.
[0005] A tablet computer plastic shell comprises a shell, wherein the shell is injection-molded by modified plastic, and the modified plastic is a PPS+CF composite material or a PC+ABS+30% GF composite material.
[0006] Preferably, reinforcing ribs are formed on the inner side of the shell.
[0007] Preferably, the reinforcing ribs are lattice-shaped.
[0008] Preferably, anti-collision corners are respectively provided at the four corners of the shell.
[0009] Preferably, the housing is used to install a screen larger than 10 inches.
[0010] In the plastic shell of a tablet computer disclosed in the utility model, the shell is injection molded by using a preset modified plastic, and the modified plastic is a PPS+CF composite material or a PC+ABS+30% GF composite material. The PPS+CF composite material is a composite material made of polyphenylene sulfide and carbon fiber, and the PC+ABS+30% GF composite material is a composite material made of polycarbonate, ABS material and 30% glass fiber. The shell injection-molded based on the above materials can replace the shell of a traditional built-in roll cage. Compared with the existing shell, the utility model not only has the characteristics of stronger rigidity and toughness, but also has a lighter component weight and a lower manufacturing cost, which better meets the application requirements. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 The structure diagram of the existing tablet computer housing and roll cage;
[0012] Figure 2 This is a structural diagram of the plastic shell of a tablet computer of the present utility model. DETAILED DESCRIPTION
[0013] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.
[0014] The utility model discloses a plastic shell for a tablet computer, see Figure 2 It includes a shell 1, which is injection-molded by modified plastic, and the modified plastic is a PPS+CF composite material or a PC+ABS+30% GF composite material.
[0015] In the above structure, the shell 1 is injection molded using a preset modified plastic, and the modified plastic is a PPS+CF composite material or a PC+ABS+30% GF composite material. The PPS+CF composite material is a composite material made of polyphenylene sulfide and carbon fiber, and the PC+ABS+30% GF composite material is a composite material made of polycarbonate, ABS material and 30% glass fiber. The proportions and manufacturing processes of these two materials are all prior art, and this embodiment does not limit them. The shell 1 injection molded based on the above materials can replace the traditional shell with a built-in roll cage. Compared with the existing shell, the utility model not only has the characteristics of stronger rigidity and toughness, but also has a lighter component weight and a lower manufacturing cost, which better meets the application requirements.
[0016] In order to further improve the physical strength of the shell 1 , in this embodiment, a reinforcing rib 10 is formed on the inner side of the shell 1 .
[0017] Specifically, the reinforcing ribs 10 are lattice-shaped. Of course, in practical applications, the reinforcing ribs 10 can also be set in other shapes. The present invention does not limit the setting of the reinforcing ribs 10 or the shape of the reinforcing ribs 10. That is, as long as the housing 1 is made of the above-mentioned modified plastic, it belongs to the protection scope of the present invention.
[0018] As an application example, anti-collision corners 11 are respectively provided at the four corners of the housing 1 .
[0019] In practical applications, the housing 1 is used to install a screen larger than 10 inches, thereby meeting the application requirements of a large-size tablet computer.
[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
