Description

Technical Field

[0001] The utility model relates to the technical field of computer keyboards, and more specifically, to a multifunctional keyboard which is easy to splice. Background Art

[0002] As an input device that matches the computer, the keyboard is the most commonly used and most important input device in computer control. It can input information such as English letters, numbers, punctuation marks, etc. into the computer.

[0003] Most of the most common keyboards are long and inconvenient to carry, so some manufacturers reduce the size of the keyboard by reducing the number of keys. However, the lack of functions will affect people's use. Therefore, detachable keyboards have begun to appear on the market, which meet the needs of easy portability and full functionality.

[0004] Most common spliced ​​keyboards are divided into only two parts: the main keyboard area and the numeric keypad area. However, the main keyboard area is still large in size, and the need for portability is still high. Moreover, most common spliced ​​keyboards are connected through data interfaces, and can be spliced ​​by simple insertion. Early use makes the interface tight, which can ensure the stability of the keyboard splicing. However, with the increase of usage time, the simple splicing structure ages and begins to loosen, affecting the stability of the assembled keyboard and affecting its use. In addition, after splitting, each area of ​​the keyboard exists independently, which is easy to be confused, collided or lost. Moreover, most common keyboards lack protective structures, and are easily damaged by dust when stacked together. Utility Model Content
