Problems solved by technology

However, whether it is magnesium alloy, aluminum alloy or hard plastic, its hardness and rigidity are not very ideal, which makes it easy for users to cause bending and deformation of the tablet during use.
At present, some tablet computers adopt the method of using reinforcement blocks inside the shell, but the reinforcement blocks are mostly made of stainless steel or ordinary titanium alloy, which is difficult to ensure the dual requirements of rigidity and thinness
There are also some technologies that use amorphous alloys as reinforcement blocks, but this greatly increases the overall cost

Abstract

The invention relates to a tablet computer. The tablet computer comprises a tablet computer body, a battery and a shell. By arranging a reinforcing block on the shell of the tablet computer and improving the component content of the reinforcing block and a preparation method, the properties such as the elasticity modulus and the strength of the shell of the tablet computer are greatly improved, and the requirements of the table computer on the comprehensive properties such as the strength and the light weight of the shell are met.

Description

technical field [0001] The invention belongs to the field of mobile communication and the field of alloys, in particular to a reinforcement block of a titanium alloy shell of a tablet computer. Background technique [0002] At present, smart devices are extremely popular. Tablet PCs are gradually replacing PCs due to their light weight and convenience. The appearance, compression resistance, and impact resistance of tablet PCs are getting more and more attention. Currently, the shells of tablet PCs are mostly made of magnesium alloy. , aluminum alloy, titanium alloy or plastic. However, whether it is magnesium alloy, aluminum alloy or hard plastic, its hardness and rigidity are not very ideal, which makes it easy for the user to cause bending and deformation of the tablet computer during use. At present, some tablet computers adopt the method of using reinforcement blocks inside the shell, but the reinforcement blocks are mostly made of stainless steel or ordinary titanium ...
