Abstract
The utility model provides a wireless keyboard, it includes wireless module and keyboard module, it still includes singlechip, human infrared sensor, LED lamp and establishes the touch sensor on the keyboard surface, singlechip and human infrared sensor establish inside the keyboard, and just human infrared sensor is connected with the singlechip, the LED lamp is established on the surface of keyboard and is connected with the singlechip, is used for giving out light, touch sensor establishes on the surface of keyboard and is connected with the singlechip, wireless module and keyboard module all are connected with the singlechip. Adopt this kind of structure, the keyboard is difficult to lose, and under black environment, the user finds the keyboard easily moreover.
Description
Technical field
The utility model relates to computer fittings technical field, is specifically a kind of Wireless Keyboard.
Background technology
The Wireless Keyboard of prior art is generally grafting USB bluetooth module on host computer, is then communicated with host computer by the bluetooth module of Wireless Keyboard, realizes the controlled in wireless of keyboard.Because keyboard is controlled in wireless, and be not connected with computer, therefore keyboard can easily be lost, or user forgets where keyboard is placed on, and uses inconvenience, and if be under night or more black environment, finds keyboard to be more not easy.
Utility model content
The technical problems to be solved in the utility model is, overcomes the defect of prior art, provides one to be not easy to lose, and under more black environment, easily finds the Wireless Keyboard of keyboard.
For solving the problems of the technologies described above, the utility model provides a kind of Wireless Keyboard, it comprises wireless module and Keysheet module, it also comprises single-chip microcomputer, infrared sensor of the human body, LED and is located at the touch sensor of surface of keyboard, described single-chip microcomputer and infrared sensor of the human body are located at keyboard, and infrared sensor of the human body is connected with single-chip microcomputer, described LED is located at the surface of keyboard and is connected with single-chip microcomputer, for luminescence, described touch sensor is located at the surface of keyboard and is connected with single-chip microcomputer, and described wireless module is all connected with single-chip microcomputer with Keysheet module.
After adopting said structure, the utility model has the following advantages: the utility model detects in certain limit whether have people by arranging infrared sensor of the human body, if someone, lighted by Single-chip Controlling LED or glimmer, until touch sensor has detected people's touch keyboard, then Single-chip Controlling LED is gone out, adopt this structure, as long as user is near keyboard, keyboard will inform the position of user's keyboard by LED, and when user is when using keyboard, then keyboard would not bright light, do not affect user to use, keyboard is not easy to lose, and under more black environment, user easily finds keyboard.
Described infrared sensor of the human body is human body pyroelectricity infrared sensor.
Described LED has multiple, and the outer Monday being arranged in keyboard encloses.Adopt this structure, lamp lights the profile that can be shown to keyboard, and convenient user finds keyboard.
Described touch sensor is capacitive touch sensors, and described touch sensor is arranged on the surface of the space bar of keyboard.General user in use, is more prone to the space bar touching keyboard, is therefore located at herein, more hommization.
Accompanying drawing explanation
Fig. 1 is block diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail:
As shown in Figure 1, the utility model provides a kind of Wireless Keyboard, it comprises wireless module and Keysheet module, it also comprises single-chip microcomputer, infrared sensor of the human body, LED and is located at the touch sensor of surface of keyboard, described single-chip microcomputer and infrared sensor of the human body are located at keyboard, and infrared sensor of the human body is connected with single-chip microcomputer, described LED is located at the surface of keyboard and is connected with single-chip microcomputer, for luminescence, described touch sensor is located at the surface of keyboard and is connected with single-chip microcomputer, and described wireless module is all connected with single-chip microcomputer with Keysheet module.
After adopting said structure, the utility model has the following advantages: the utility model detects in certain limit whether have people by arranging infrared sensor of the human body, if someone, lighted by Single-chip Controlling LED or glimmer, until touch sensor has detected people's touch keyboard, then Single-chip Controlling LED is gone out, adopt this structure, as long as user is near keyboard, keyboard will inform the position of user's keyboard by LED, and when user is when using keyboard, then keyboard would not bright light, do not affect user to use, keyboard is not easy to lose, and under more black environment, user easily finds keyboard.
Described infrared sensor of the human body is human body pyroelectricity infrared sensor.In the present embodiment, when keyboard is in holding state, the sensing range of human body pyroelectricity infrared sensor is 2 meters, when detect in 2 meters have people time, then control LED bright or flicker, then control LED when displacement transducer detects mobile and go out, keyboard is in running order, until when human body pyroelectricity infrared sensor detects no one within the scope of 2 meters, then keyboard is in holding state again.
Described LED has multiple, and the outer Monday being arranged in keyboard encloses.Adopt this structure, lamp lights the profile that can be shown to keyboard, and convenient user finds keyboard.LED can according to the outside surface of certain pitch arrangement at keyboard.
Described touch sensor is capacitive touch sensors.Generally touch sensor can be arranged on the outside surface of the space bar of keyboard, when people sees keyboard, generally all can touch the space bar of keyboard, now touch sensor sends a signal to single-chip microcomputer, and single-chip microcomputer just can control lamp and go out, simple and convenient.
