Cursor control button and luminous keyboard thereof

Abstract

The invention provides a cursor control button and a luminous keyboard of the cursor control button. The luminous keyboard comprises a base plate, a backlight module, a plurality of input buttons and a lightproof piece. The backlight module and the input buttons are placed on the two sides of the base plate respectively, and the lightproof piece is arranged between the base plate and the backlight module. The cursor control button comprises a bearing structure, an opening structure and at least one lightproof portion. At least one blow hole is formed in the bearing structure and the bearing structure is placed on the base plate. The opening structure is formed in the position, corresponding to the bearing structure, of the lightproof piece, and the bearing structure is embedded into the backlight module through the opening structure. The at least one lightproof portion is connected to the position, corresponding to the at least one blow hole, of the periphery of the opening structure, and when the bearing structure is embedded into the backlight module through the opening structure, the lightproof portion is attached to the bearing structure in a bent mode so as to cover the blow hole. According to the cursor control button and the luminous keyboard, the lightproof portion is attached to the bearing structure in the bent mode so as to cover the blow hole in the lateral wall portion of the bearing structure, and therefore light leakage of the luminous keyboard at the position for bearing the cursor control button is reduced.

Description

technical field [0001] The invention relates to a cursor control key and its luminous keyboard, in particular to a cursor control key and its luminous keyboard which can reduce the light leakage of the luminous keyboard at the place where the cursor control key is loaded. Background technique [0002] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Recently, with the improvement of consumers' visual demands, a luminous keyboard has become a new development direction of the industry. In addition, in order to improve the user's pleasure in operating the keyboard, a cursor control key (pointing stick cursor key) that can be used to operate the mouse cursor has emerged as the times require. The known cursor control buttons, such as U.S. Publication No. 5568987, include a force sensing module and a rod coupled to the force sensing module. When the rod is toggled, ...

AI Technical Summary

Problems solved by technology

Therefore, the light generated by the backlight module of the luminous keyboard can be transmitted to the outside of the luminous keyboard through the above-mentioned holes, resulting in light leakage of the luminous keyboard at the load-bearing structure for carrying the force sensing module, and further causing the problem of the luminous keyboard.
