Amount, can complete the figure that can not be drawn by hand in some respects.Professional for study civil engineering and Machine Design manufacture
For student, CAD courses are its compulsory course.
At present, the teaching of CAD courses is that teacher is demonstrated and explained before computer mostly, teacher operation when only
Computer and keyboard can be watched attentively, it is impossible to carry out study situation that is interactive and observing student with classmate during operation, seriously
It has impact on teaching efficiency.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of CAD drawing keyboard special, can be in CAD drawing courses
In it is more convenient.
The utility model solves above-mentioned technical problem by following technological means：
A kind of CAD drawing keyboard special, including keyboard body and wrist strap, the supporting plate of the middle part setting of the wrist strap are described
The front end of supporting plate and the back side of keyboard body are connected, and mode switching key module, CAD drawing are provided with the keyboard body soon
Prompt key module and wireless signal transceiver module, in addition to power module and the processor that is connected with the power module,
The processor is electrically connected with mode switching key module, CAD drawing shortcut key-press modules and wireless signal transceiver module respectively
Connect, the processor is using 8 8051 architecture processor chips.
What is reached is had the technical effect that, wrist strap can be enclosed in wrist, and the front of keyboard body is relative with the centre of the palm, and finger can
To tap keyboard, when teacher carries out CAD teaching, the use of the keyboard compared with conventional keyboard flexibly, forms aerial keyboard, Jiao Shiwu
Need to only rest on before computer and be demonstrated, teacher no matter stand where, it is only necessary to finger tapping keyboard can complete operation,
It is remarkably improved teaching efficiency.Transmitted a signal to after mode switching key module, CAD drawing shortcut key-press modules is touched
Processor, processor transmits a signal to computer by wireless signal transceiver module, and then controls computer.
Further, the mode switching key module includes AutoCAD classical modes switch key, three-dimensional modeling pattern switching
Key, isometric mode switching key.In CAD teaching processes, one in three switch keys is tapped as needed, you can to realize
AutoCAD classics, three-dimensional modeling, the switching of isometric mode of operation.
Further, the CAD drawing shortcuts key-press module includes being identified with representing difference on multiple buttons, each button
The figure of drawing function.Keypress function includes the shortcut key of picture rectangle, circle, ellipse, straight line, camber line, SPL etc.
With the shortcut key of the assisted mapping such as duplication, movement, rotation, mirror image, array, scaling.The need for according to drawing, it is only necessary to tap
The corresponding shortcut key of order.
Further.The length of the keyboard body is 10-15cm, and the width of the keyboard body is 6-8cm.Keyboard body
Size match with hand size, be easy to operation.
Further, the supporting plate afterbody is curved, and the intrados of arc pallet can be bonded to each other with wrist portion.
Further, be provided with elastomer on the intrados, it is described can be bonded to each other with wrist.
Further, the supporting plate is anterior is slidably matched between keyboard body back.Wrist is adjusted according to user's hand-type
Between band and keyboard body
The beneficial effects of the utility model：CAD drawing keyboard specials can be enclosed in wrist by wrist strap, keyboard body
Front is relative with the centre of the palm, and finger can tap keyboard, and when teacher carries out CAD teaching, the keyboard is flexible compared with conventional keyboard, simultaneously
Coordinate air mouse to use, then teacher is demonstrated without only resting on before computer, teacher no matter stand where, it is only necessary to
Finger tapping keyboard can complete operation, and teaching effect can be remarkably improved with the situation of close observation student while operation
Really.
