Lighting keyboard

Abstract

The invention relates to a lighting keyboard. The lighting keyboard comprises at least one lighting element, a film circuit board, a plurality of keys, a fixing plate and a proximity sensor; the fixing plate comprises a plurality of holes, a plurality of connecting areas and a plurality of fixing areas; the plurality of fixing areas are positioned among the plurality of holes to fix a plurality of elastic elements of the plurality of keys; the proximity sensor comprises an induction antenna circuit which is arranged in each connecting area or each fixing area of the fixing sheet to sense a sensing distance of a sensed object entering. According to the lighting keyboard, the proximity sensor is arranged to achieve the purpose of automatically turning on or turning off the lighting function of the lighting keyboard; in addition, the induction antenna circuit is arranged on the fixing sheet to expand the arrangement range of the induction antenna circuit; therefore, the lighting keyboard meets the development trend of lightweight, thin, short and small keyboards.

Description

technical field [0001] The present invention relates to a luminous keyboard, in particular to a luminous keyboard with the function of sensing a sensed object entering a sensing distance. Background technique [0002] A keyboard is an interface device commonly used to input text or commands to information devices such as desktop computers, notebook computers, mobile phones, and tablet computers. Please refer to figure 1 , figure 1 It is a diagram showing the appearance of an existing keyboard. The existing keyboard 1 has a plurality of keys 10. When the user touches these keys 10 with his fingers, a corresponding signal will be generated to the information device to make it perform key functions. For example, when the key 101 is pressed, symbols such as English letters can be input. , when the key 102 is pressed, numbers can be input, and when the key 103 is pressed, various functions can be quickly executed. [0003] When the user uses the keyboard in a low-light enviro...

Problems solved by technology

However, in the Chinese Utility Model Patent No. 201440241, the induction antenna 27 is arranged on the film circuit board 24 or is arranged around the casing 28. When the induction antenna 27 is arranged on the film circuit board 24, the induction antenna 27 needs to avoid Open the circuit on the film circuit board 24, so the installation position of the induction antenna 27 is greatly restricted, and when the induction antenna 27 is arranged around the housing 28, the housing 28 must be enlarged to accommodate the induction antenna 27 , so that it does not conform to the trend of light-emitting keyboards towards lightness, thinness, and miniaturization, and in the above two cases, the distance between the sensing antenna 27 and the metal shrapnel layer 23 is too close, which is prone to signal interference problems
