Embodiment 1

[0024] A keyboard with partially virtual laser keys, such as figure 1 As shown, it includes a keyboard main body 1, and the keyboard main body 1 includes a keyboard upper cover body 2, a circuit board 3, a bottom plate 4 and a virtual laser keyboard assembly 5; a plurality of keyboard keys are embedded on the surface of the keyboard upper cover body 2, and the circuit board 3 is located on the keyboard In the cavity between the cover body 2 and the bottom plate 4;

[0025] The virtual laser keyboard assembly 5 includes a linear motor 6, a projection module 7, a word infrared transmitter 8, a CMOS sensor 9 and a photosensitive module 10; the linear motor 6, the projection module 7, the CMOS sensor 9 and the photosensitive module 10 are arranged on the circuit board in sequence On the upper right side of 3, a word infrared emitter 8 is arranged on the right lower part of the circuit board 3, and correspondingly, the right side of the cover body 2 on the keyboard is provided with...

Embodiment 2

[0027] Such as Figure 4 As shown, a keyboard with partial virtual laser keys, on the basis of Embodiment 1, the physical key area on the cover surface of the keyboard is the main key area and the functional area, and the virtual key area projected by the projection module is the editing key area and numeric keypad.

Embodiment 3

[0029] Such as Figure 5 As shown, a keyboard with partial virtual laser keys, on the basis of Embodiment 2, the physical key area on the surface of the cover body on the keyboard is the main key area and the functional area, and the virtual key area projected by the projection module is the editing key area Or / and the numeric keypad, switch and display the editing keypad and the numeric keypad by setting the keypad selection key 16 on the cover surface of the keyboard, or simultaneously display the editing keypad and the numeric keypad.

Abstract

The invention discloses a keyboard with partial virtual laser key positions, which comprises a keyboard body. The keyboard body comprises a keyboard upper cover body, a circuit board, a bottom plate and a virtual laser keyboard assembly. The virtual laser keyboard assembly comprises a linear motor projection module, a linear infrared emitter and a CMOS sensor. The linear motor, the projection module, the linear infrared emitter and the CMOS sensor are arranged on the same side edge of the circuit board. When part of functions of the virtual keyboard are needed, a virtual keyboard switch is pressed down, the projection module projects a keyboard image on an interface on the right side of the keyboard body, when a finger interacts with a certain key position of the interface, reflected lightcan be captured by the CMOS sensor, so that the input key position is recognized, and meanwhile, the linear motor feeds back each action in a vibration generating mode. The keyboard is simple in structure, convenient to use and practical, the product is more portable and miniaturized, and the keyboard has the functions of all complete key positions.

Description

technical field [0001] The invention belongs to the technical field of keyboards, and in particular relates to a keyboard with partial virtual laser key positions. Background technique [0002] In order to meet the needs of portability, practicality and individualization, the keyboard products currently on the market generally adopt the method of reducing the keys outside the main function area. Although the lack of some keys can be made up by combination keys, the user operation is still not as good as full keys. Bit keyboard is convenient and fast. Portability and functionality cannot be balanced. In order to improve portability, only some keys can be canceled to reduce practical functions, and vice versa. [0003] The virtual laser keyboard uses light projection technology, which can project a virtual keyboard on almost any plane. The applicability technology of the virtual keyboard studies the user's finger movements, decodes and records the keyboard strokes. By addin...
