Abstract
The utility model provides a wireless keyboard, it includes wireless module and keyboard module, it still includes singlechip, LED lamp, human infrared sensor, vibrating module and displacement sensor, vibrating module, singlechip, displacement sensor and human infrared sensor all establish inside the keyboard, and just human infrared sensor, vibrating module, displacement sensor all are connected with the singlechip, the LED lamp sets up the surface at the keyboard, and the LED lamp 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 one be grafting USB bluetooth module on host computer, then communicated with host computer by the bluetooth module of Wireless Keyboard, realize 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, LED, infrared sensor of the human body, vibration module and displacement transducer, described vibration module, single-chip microcomputer, displacement transducer and infrared sensor of the human body are all located at keyboard, and infrared sensor of the human body, vibration module, displacement transducer are all connected with single-chip microcomputer, described LED is arranged on the outside surface of keyboard, and LED is connected with single-chip microcomputer, 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, vibrated by Single-chip Controlling vibration module and LED lights and sends warning, until displacement transducer detects that keyboard has movement, then Single-chip Controlling LED is gone out and is controlled vibration module and quits work, adopt this structure, as long as user is near keyboard, the vibration module of keyboard will vibrate the position of pointing out user's keyboard, and when user picks up keyboard or mobile keyboard, the vibration of keyboard just stops, LED also can knock out, 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 vibration module is vibrating motor.
Institute's displacement sensors is linear acceleration transducer.This sensor can detect the movement of object, as long as detect in the present embodiment that keyboard moves just can send a signal to single-chip microcomputer, single-chip microcomputer just controls vibration module and stops vibration, and LED is gone out, simple and convenient.
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, LED, infrared sensor of the human body, vibration module and displacement transducer, described vibration module, single-chip microcomputer, displacement transducer and infrared sensor of the human body are all located at keyboard, and infrared sensor of the human body, vibration module, displacement transducer are all connected with single-chip microcomputer, described LED is arranged on the outside surface of keyboard, and LED is connected with single-chip microcomputer, described wireless module is all connected with single-chip microcomputer with Keysheet module.LED is used for luminous, provides a LED to be arranged on the outside surface of keyboard in the present embodiment.
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, vibrated by Single-chip Controlling vibration module and LED lights and sends warning, until displacement transducer detects that keyboard has movement, then Single-chip Controlling LED is gone out and is controlled vibration module and quits work, adopt this structure, as long as user is near keyboard, the vibration module of keyboard will vibrate the position of pointing out user's keyboard, and when user picks up keyboard or mobile keyboard, the vibration of keyboard just stops, LED also can knock out, 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 vibration module vibration and LED bright, then stop when displacement transducer detects mobile vibration and control LED 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 vibration module is vibrating motor.
Institute's displacement sensors is linear acceleration transducer.This sensor can detect the movement of object, as long as detect in the present embodiment that keyboard moves just can send a signal to single-chip microcomputer, single-chip microcomputer just controls vibration module and stops vibration, and LED is gone out, simple and convenient.Certainly the displacement detection devices such as gyroscope can also be adopted.
