Embodiment
Below against accompanying drawing, by the description to embodiment, the embodiment to the present invention makees further details of
Explanation, it is therefore an objective to help those skilled in the art to have more complete, accurate and deep reason to design of the invention, technical scheme
Solution, and contribute to it to implement.
As shown in Figures 1 to 4, the present invention is a kind of electronic blackboard note taking device, is protected in time in the form of notes
The content that teacher attends class is deposited, is easy to student's review and consolidation.
Show the embodiment of the present invention as shown in Figure 1 to Figure 3：A kind of electronic blackboard note taking device, it is special
Levy and be：Including blackboard 1, electromagnetism range sensor 2, data wire 3, computer 4 and the magnetic powder pen cap 5, the electromagnetism Distance-sensing
Device 2 is arranged on blackboard 1, and the data wire 3 one is realized with four electromagnetism range sensors 2 to be electrically connected with, other end and electricity
Brain 4 is electrically connected with, and the magnetic powder pen cap 5 is adsorbed on blackboard 1.
In the present embodiment, the blackboard 1 is provided with stainless steel frame 11, facilitates the magnetic powder pen cap 5 to adsorb on blackboard 1.
In the present embodiment, 2 points of the electromagnetism range sensor is an electromagnetism range sensor 21, No. two electromagnetism distance biographies
Sensor 22, No. three electromagnetism range sensors 33 and No. four electromagnetism range sensors 24, four electromagnetism range sensors 2 are installed
At four angles of blackboard 1, and relative position is fixed, determined simultaneously using four electromagnetism range sensors 2 target magnet 53 away from
From the multiple position that target magnet 53 is determined with triangle polyester fibre principle improves positioning precision, so as to preferably record teacher
With the handwriting trace of chalk, reach the purpose of note taking.
In the present embodiment, the magnetic powder pen cap 5 is by plastic casing 51, rubber pneumatic bag 52, target magnet 53 and plastic movable
Stopper rod 54 is constituted, and the rubber pneumatic bag 52 is fixedly connected with plastic casing 51, and the target magnet 53 is interior with plastic casing 51
Wall is fixedly connected, and the plastic movable stopper rod 54 is threadedly coupled through target magnet 53, the plastic movable stopper rod 54, plastic casing 51
The sealing of the inner chamber constituted with rubber pneumatic bag 52 is good, and the structure well can clamp chalk, by chalk sleeve in magnetic
In chalk sleeve 5.
In the present embodiment, some raised 521, described raised 521 are uniformly provided with the rubber pneumatic bag 52 can increase rubber
Frictional force between glue air bag 52 and chalk, makes clamping more firm.
Specific works mode is illustrated with specific embodiment below：
Embodiment 1：
Raised 521 structural representation of rubber pneumatic bag 52 shown in the sectional view and Fig. 4 of the magnetic powder pen cap 5 as shown in Figure 3
Figure, the process of the clamping chalk of the magnetic powder pen cap 5 is as follows：Inserted when chalk tail end in the magnetic powder pen cap 5, twist plastic movable stopper rod
54, the gas of compression inner chamber can be such that rubber pneumatic bag 52 expands outward, and the rubber pneumatic bag 52 now with projection 521 can be chalk clamp
That holds is increasingly tighter, because plastic movable stopper rod 54 with target magnet 53 is to be threadedly coupled, plastic movable stopper rod 54 will not active back
Move back, chalk can be always maintained at the state clamped, when changing chalk, it is only necessary to twist plastic movable stopper rod 54 and shrink back, just can pine
Open chalk.
Embodiment 2：
