Description

Technical Field

[0001] The utility model relates to the technical field of protective cases, and particularly relates to a magnetic separation type protective case for a tablet computer. Background Technique

[0002] Tablet computers are commonly used electronic devices for people's life, entertainment and mobile office. Their bending resistance is poor. When some people place them on the table or bed and accidentally press on the tablet computer, it is very likely to bend the tablet computer. In recent years, with the progress of the times and the continuous development of technology, tablet computers are constantly pursuing extreme thinness and lightness, which also means that the risk of being bent during daily use of tablet computers is increasing. The expensive devices have made the vast majority of people develop the habit of wearing protective cases.

[0003] Currently, the protective cases applied to tablet computers on the market are classified as follows:

[0004] From the perspective of structure:

[0005] 1. Full-wrap protective case: The main form of this type of protective case is similar to the outer shell of a tablet computer, which will wrap the sides and back of the tablet computer entirely. Generally, there is a pen slot at its long side, and the front cover is usually connected to the back panel. The advantages of this type of protective case are wide protection area and many additional functions, but the disadvantages are that it is relatively bulky, difficult to disassemble, and at the same time, the manufacturing process and steps are relatively more complex, and the cost is relatively high.

[0006] 2. Double-sided clip protective case: The form of this type of protective case is like a book page that can be folded in half. The back panel and the front cover are connected together through the long side, without a pen slot, and the surface is usually treated with leather. The advantages of this type of protective case are fashionable and beautiful, and light in weight. The disadvantages are that the protection strength is insufficient, and for some usage scenarios where the front cover is not needed, the whole case still needs to be removed to use.

[0007] From the perspective of materials:

[0008] 1. Protective case made of acrylic material: Acrylic material is easy to process, has good transparency and low density, so it has good decorative properties and is light in weight. However, hardness is an important parameter in the production process and technology of acrylic plates. The hardness of ordinary acrylic plates is average and cannot meet the anti-bending needs of users.

[0009] 2. Protective case made of manganese steel material: Manganese steel material is resistant to impact, pressure and wear, and the made back panel has good anti-bending performance, but its density is relatively large, and the holding feel is relatively heavy, which will bring a burden to users when using.

[0010] 3. Protective case made of PC material: PC material is energy-saving, light in weight and has good transparency. Generally, it is also made into a transparent case. However, this material itself has a certain degree of bendability and poor anti-bending performance.

[0011] In summary, the protective cases currently applied to tablets generally have the disadvantages of inconvenient use and poor anti-bending performance, and there is a need for a protective case that is light in weight, convenient to use, and has good anti-bending performance.
