Description
Technical field
The present invention relates to fields of measurement, particularly a kind of electronic scale with laser virtual keyboard.
Background technology
Electronic scale is a kind of electronic weighing device using modern electronic technology, can meet and solve to propose in actual life
Quick, accurate, automatic weighing requirement, while the error caused by artificial weigh can be effectively eliminated, so electronic scale exists
It is widely used in people's life, and traditional electronic scale generally use is mechanical key or touch key-press, it is lacked
Point is the usable floor area that keyboard occupies scale body, and push button longevity is not grown.
The content of the invention
In order to solve the above technical problems, the object of the present invention is to provide a kind of electronic scale with laser virtual keyboard.
The technical solution adopted by the present invention is：
A kind of electronic scale with laser virtual keyboard, including weighing platform, are provided with weighing sensor on the weighing platform
The weight information born for detection weighing platform；
Display, the display are arranged on weighing platform；
Laser keyboard maker, the laser keyboard maker are set over the display；
Master control borad, the master control borad are electrically connected with weighing sensor, display and laser keyboard maker respectively.
The laser keyboard maker includes photographing module, laser emitter and receiver, the laser be used for
Outside projection virtual laser keyboard, the receiver is used to receive to be believed using the laser reflected when touching virtual laser keyboard
Number, the photographing module is for the position for the virtual key position for judging to use on virtual laser keyboard.
Present invention additionally comprises stent, one end of the stent is fixed at weighing platform, the other end and display and is hinged.
The weighing platform bottom is provided with the leg being used to support.
Beneficial effects of the present invention：
The present invention sets laser keyboard maker on weighing platform, instead of traditional keyboard, reduces and occupies scale body
Usable floor area, service life length, practicality are good.
Brief description of the drawings
The embodiment of the present invention is described further below in conjunction with the accompanying drawings.
Fig. 1 is the stereoscopic figure of the present invention.
Fig. 2 is the sectional view of the present invention.
Fig. 3 is the use principle figure of the present invention.
Fig. 4 is the principle of the present invention block diagram.
Embodiment
As Figure 1-Figure 4, a kind of electronic scale with laser virtual keyboard, including weighing platform 1, display 2, laser key
Disk maker 3 and master control borad 6, are provided with what weighing sensor 7 bore for detection weighing platform 1 on the weighing platform 1
Weight information, the display 2 are arranged on weighing platform 1, which is set on a display 2, the master control borad
6 are electrically connected with weighing sensor 7, display 2 and laser keyboard maker 3 respectively, and the present invention is generated using laser keyboard
Device 3 replaces traditional keyboard, reduces the usable floor area for occupying scale body, and service life is grown, and practicality is good.
The laser keyboard maker 3 includes photographing module 31, laser emitter 32 and receiver 33, the laser
For projecting virtual laser keyboard to outside, the receiver 33 is used to receive to be reflected using when touching virtual laser keyboard
Laser signal, the photographing module 31 is used to judge the position of virtual key position used on virtual laser keyboard, Laser emission
The laser that device 32 produces is projected on desktop according to certain keyboard layout, and laser pickoff 33 can identify that hair desktop reflects
Signal, with reference to the imaging of photographing module 31, when finger touches on the virtual keyboard, just can recognize that finger by which
On button, so as to be successfully entered information.
Present invention additionally comprises stent 4, one end of the stent 4 is fixed at weighing platform 1, the other end and display 2 and cuts with scissors
Connect in order to which display 2 moves, so that laser keyboard maker 3 moves, flexibly change the projection side of laser keyboard maker 3
To user-friendly.
The weighing platform bottom is provided with the leg 5 being used to support, and has pooling feature.
The foregoing is merely the present invention preferred embodiments, the present invention is not limited to the above embodiment, if with
Essentially identical means realize that the technical solution of the object of the invention is belonged within protection scope of the present invention.
