Description

Technical Field

[0001] The utility model relates to the technical field of tablet computers, in particular to a fixing structure for assembling front and rear shells of a tablet computer. Background Art

[0002] A tablet computer, also known as a portable computer, is a small, portable personal computer that uses a touch screen as the basic input device. The touch screen (also known as digital tablet technology) allows users to perform operations through a stylus or digital pen instead of a traditional keyboard or mouse. Users can input through built-in handwriting recognition, an on-screen soft keyboard, voice recognition, or a real keyboard (if the model is equipped with it). Tablet computers are highly integrated, with the front and rear shells wrapping the internal circuit board and display, so the connection of the shell is particularly important.

[0003] The inventor has found in his daily work that most of the existing tablet computers abandon traditional bolt connections and use adhesive fixation in pursuit of aesthetics, which makes it easy for glue to overflow when the tablet is installed. When the tablet computer fails and needs to be repaired, it is difficult to quickly disassemble and assemble it. At the same time, when the adhesive is heated, it is easy to cause the circuit board components to become desoldered or fall off, which poses certain hidden dangers and requires improved operations.
