Background technology

Keyboard is modal computer entry device, and it is widely used on microcomputer and various terminal unit.Computer operation person passes through keyboard to the various instruction of computer input, data, the work of command computer, it may be said that keyboard is one of equipment most frequently used in computer equipment.User's life-time service keyboard works, and especially needs to carry out for a long time the staff of official documents and correspondence editor, symptom that long-time operation keyboard can cause that hand is ached etc..

For the problems referred to above; at present; the Chinese patent of Publication No. CN104423600A discloses a kind of keyboard structure meeting ergonomics; its drip irrigation device is: include a keyboard; described keyboard includes that key part and hand rest part, described hand rest part are made up of lower base and top memory body, and described top memory body is removably mounted in described lower base; described top memory body is made up of memory sponge and protective layer, and described hand rest part is removably mounted on described keyboard.

Although this keyboard reduces the fatigue strength of user by arranging hand rest, but the hand rest of this keyboard cannot draw in so that user is not when using keyboard, and hand rest occupies the area that desktop is bigger, causes user's not aspect to carry out other work before computer.

It is thus desirable to propose a kind of new scheme to solve this problem.

Utility model content

The deficiency existed for prior art, the purpose of this utility model is to provide a kind of keyboard, by hand rest is slidably connected at the bottom of keyboard matrix, and makes hand rest skid off and draw in matrix by the way of rack and pinion engagement.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of keyboard, including matrix and the button being arranged on matrix, described base bottom slidably connects hand rest, described hand rest connects to be had drive mechanism and skids off and draw in base bottom by drive mechanism driving, and described drive mechanism includes that the tooth bar being fixedly connected on hand rest engages the gear with driving tooth bar sliding and is fixedly connected on matrix the motor driving pinion rotation with tooth bar；Being provided with range sensor in described matrix, described range sensor is connected with timer, controller, driver and motor in turn；When staff enters into the induction range of described range sensor, described range sensor sends an induced signal to timer, described timer response is in induced signal and starts timing, reaching when described timer to send a forward control signal to controller during Preset Time, controller makes hand rest skid off matrix in response to forward control signal and by the rotating forward of driver control motor；When staff departs from the induction range of described range sensor, described range sensor sends an induced signal again, described timer response is in induced signal and starts timing, reaching when described timer to send a reverse control signal to controller during Preset Time, described controller makes hand rest draw in response to reverse control signal and by driver control motor reversal.

By using technique scheme, by the way of rack and pinion engagement, make hand rest can skid off and draw in matrix under the drive of motor, and without people's Manual push-pull hand rest；Range sensor, timer and controller are set, it is achieved that automatically the skidding off and draw in of hand rest.

This utility model is further arranged to: described matrix be provided be connected with described controller one for control motor rotate forward so that the start button and that skids off of hand rest for controlling motor reversal so that the close key that draws in of hand rest.

By using technique scheme, start button and close key are set, skidding off and drawing in of hand rest can also be realized by operation start button and close key, it is to avoid when range sensor breaks down, hand rest cannot skid off or draw in.

This utility model is further arranged to: described hand rest includes substrate and the flexible support portion being fixedly connected on substrate.

By using technique scheme, flexible support portion is fabricated from a flexible material, and is used for supporting user's hand, improves user and uses the comfort of keyboard.

This utility model is further arranged to: described hand rest is provided with the heating plate electrically connected with power module, and described matrix is provided with the regulation switch being connected for regulating heating plate temperature and keying with heating plate.

By using technique scheme, heating plate is set, when winter, temperature was relatively low, unlatching heating plate heats, keeping user's hand warm, opening and closing of regulation on-off control heating plate can control the maximum temperature that heating plate heats simultaneously, and user can regulate voluntarily to oneself comfortable temperature.

This utility model is further arranged to: described heating plate uses PTC heating plate.

In sum, this utility model has the advantages that

One, by hand rest is slidably connected at the bottom of keyboard matrix, and makes hand rest skid off and draw in matrix by the way of rack and pinion engagement, reduces the area of keyboard grabbing；

Its two, range sensor, timer and controller are set, it is achieved the automatic gathering of hand rest；

Its three, heating plate is set, when temperature is relatively low keep hand warm.
