Advantageous effect of the invention
The present invention the mobile brain wave acquisition device with screw electrode, as a result of helical support member, thus into
When row brain wave acquisition, helical support member slowly rotates under the drive of motor, to effectively pass through hair so that screw electrode
Piece is in direct contact with scalp, effectively prevents influence of the hair to eeg signal acquisition.
Further, since the number of turns of screw electrode piece is greater than or equal to a circle, when worn, headband presses to screw motor
When, the electrode slice that spiral one is enclosed can be contacted with maximum area with scalp, improve contact area, be conducive to eliminate noise.
Description of the drawings
Fig. 1 is the overall structure diagram of the mobile brain wave acquisition device with screw electrode；
Fig. 2 is the structural schematic diagram of screw electrode.
Specific implementation mode
Illustrate the specific implementation mode of the present invention below in conjunction with attached drawing.
As depicted in figs. 1 and 2, the mobile brain wave acquisition device of screw electrode is carried, including：It is head band 11, multigroup
Electrode supporting bar 13, motor 14, helical support member 16 and screw electrode piece 17.
There is head band 11 elasticity, when use to be stuck in the head of user.
Multi-group electrode supporting rod 13 is arranged in the both sides of head band 11, electrode supporting bar 13 arch upward upwards it is arc-shaped,
One end of electrode supporting bar 13 is rotatablely connected with headband, and the other end is free end, is fixedly connected with motor 14.
Motor 14 is arranged on each electrode supporting bar 13,
Helical support member 16, the output axis connection of one end and motor 14, the other end are free end, the number of helical support member 16
Amount is consistent with the quantity of electrode supporting bar 13, and corresponds.The working face of helical support member 16 is plane, in order to spiral
Electrode slice is fixed in the above, while can increase the contact area with scalp.The working face of helical support member 16 refers to spiral branch
The spiral of support member 16 is towards the side in scalp direction, the i.e. downside at the visual angles Fig. 2.
As shown in Fig. 2, screw electrode piece 17, is arranged on the working face of helical support member 16, shape and helical support member
16 match.The starting point of screw electrode piece 17 is arranged on the free end of helical support member 16, then along helical support member 16
Spiral upwardly extend.It is to be fixedly connected between screw electrode piece 17 and helical support member 16.
The number of turns of screw electrode piece 17 is greater than or equal to a circle.So that when wearing, when headband presses to helical support member 16,
Screw electrode piece 17 is also compressed therewith, and compressed screw electrode piece 17 forms annular, can be with maximum area and scalp
Contact, improves contact area, is conducive to eliminate noise.
In some embodiments, the output axis connection that one end of helical support member 16 passes through connecting rod 15 and motor 14.
The effect of connecting rod 15 is can to extend the length of electrode, and hair is allowed to be lacked from what connecting rod 15 and helical support member 16 were formed
It is skidded off in mouthful, hair is prevented to be sandwiched between helical support member 16 and motor 14.
Motor 14 is stepper motor, so that the rotation of helical support member 16 is slower, it will not damaged scalp.
Mobile brain wave acquisition device with screw electrode also has first to accommodate storehouse 12 and second and accommodates storehouse 18, setting
At the both ends of headband.First accommodates in storehouse 12 with charged lithium cells.Second accommodates in storehouse 18 with control module, control brain electricity
The movement of the acquisition and motor 14 of signal.
When in use, the mobile brain wave acquisition device with screw electrode to be worn on to the head of user first so that
Helical support member 16 is compressed.Then start motor 14, drive helical support member 16 slowly to rotate several circles, at this time spiral support
The front end of part 16 can pass through hair, and due to the effect of spiral so that drive and be all located at for one section before helical support member 16
Below hair, contacted with scalp.Third step starts brain wave acquisition process, carries out brain wave acquisition.
