Left front volume bioelectrical signals, the electrode sensor on right side gather right forehead bioelectrical signals.Described telecommunication circuit 4 and 2 electricity
Pole sensor 3 is connected, and the bioelectrical signals that 2 electrode sensors 3 gather are transferred to signal processing unit 5 by telecommunication circuit 4.Institute
The signal processing unit 5 stated is connected with telecommunication circuit 4, and receive that telecommunication circuit 4 transmits is gathered by 2 electrode sensors 3
Bioelectrical signals, and signal is handled.
Described head hoop is worn on the head of user, and at least part of and wearer head when in use
Skin contact.Fig. 2 is to wear the schematic diagram overlooked downwards from crown direction after head hoop.Described head hoop can also be one complete
Annular, referring to Fig. 3.
In this example, described support ring 1 can head with flexural deformation, the adhered shape of the support ring 1 after flexural deformation
The profile of portion's forehead.Described buffer bar 2 can follow the flexural deformation of support ring 1.Described electrode sensor 3 can be can
Bending, deformation or it is non-deformable.Because buffer bar 2 is fixed on the inner side of support ring 1, so support ring 1 is curved
Song deformation can synchronous drive buffer bar 2 flexural deformation, the electrode sensor that the deformation and then drive of buffer bar 2 are fixed thereon
3 deformation or movement.As shown in figure 4, because external force acts on, if support ring 1 inwardly puts on power 10 (towards cephalad direction)
Buffer bar 2, then head simultaneously can give buffer bar 2 certain resistance 11, the quilt under the interaction of power 10 and power 11 of buffer bar 2
Crimp, buffer bar 2 are extruded, and the electrode sensor 3 that is fixed thereon can be driven to oppress wearer's head, so as to wearing
Person's skin of head 12 keeps good direct contact, simultaneously because the deformation of buffer bar absorbs partial pressure, can mitigate head
The external pressure that portion is subject to；Or opposite situation, as shown in figure 5, in the case where external pressure diminishes, support ring 1 is due to certainly
The outwards deformation (backwards to cephalad direction) of the elasticity of body, buffer bar 2 is because the elasticity of itself is also to both sides spread apart, and it is to head side
To unfold and drive the electrode sensor 3 that is fixed thereon to oppress wearer's head, so as to be kept with wearer's head skin 12
Good direct contact.
Further, in the case that support ring 1 does not deform, buffer bar 2 also can because with head contact stress
And occur bending and deformation, and drive electrode sensor 3 to keep good with wearer's head and directly contact.It is curved described by above-mentioned
Bent, deformation can be described as the opening of random direction, close up, distorts, the compression of random direction or unfold.
In this example, support ring 1 is made using the mode and material of metal bag silica gel.As shown in fig. 6, wherein support ring 1
Interior metal piece 22 uses manganese steel quenching technical, then using the method for mixed injection molding, in manganese steel surrounded a layer thickness 1mm
± 1mm support ring external flexible pro-skin silica gel 21, silica gel select the material of inclined flexibility.The support ring 1 such as Fig. 7 finally manufactured
It is shown, possess good elasticity and portability, weight can accomplish 30g ± 10g or so, can be very good to be bonded the wheel on head
It is wide.It is gently soft during pro-skin silica gel contact head skin.The inner side of support ring 1 (face contacted with buffer bar) structure design is fluted
23, for assisting to fix buffer bar 2.
In this example, buffer bar 2 is made using flexible pro-skin silica gel strip, as shown in figure 8, buffer bar 2 is shaped as arc, it is interior
Portion's structure is hollow shape, lumen width 8mm ± 2mm, and silica gel selects the material of inclined flexibility.As shown in figure 9, silica gel back is opened
There is gap 32, available for installing telecommunication circuit；(face on patch head) reserves the gap of 4 fixed electrode sensors 3 on the inside of silica gel
31；Simultaneously to ensure silica gel favorable elasticity, M shapes hollow cavity 33 is designed in the sidewall symmetry of silica gel, when buffer bar 2 is being propped up
When pushing out ring 1 and the Bidirectional-squeezing on head, M shape structures can ensure that buffer bar 2 is quickly compressed, when support ring 1 is away from head, M
Font cavity body structure spread apart, therefore the pressure of wearer's head can be alleviated.Its internal M shapes hollow cavity 33 is also used for hiding
Telecommunication circuit 4.
In this example, 2 electrode sensors 3 as shown in Figure 10 are devised, gather forehead FP1 and forehead FP2 areas respectively
The brain electrical biological signals in domain.Its material uses 1mm ± 0.5mm flexible FPC, outside plating layer of metal film.Flexible FPC can
Ensuring electrode sensor 3 has good toughness, when electrode slice contacts the forehead skin of wearer, the sense that does not stimulate and oppress
Feel, top layer electroplating metal film has good electric conductivity, the aggregation of minimizing electrostatic, can collect the head life of high quality
Thing electric signal.Electrode sensor 3 passes through pad 41 and the connection communication circuit 4 of pad 42.
In this example, telecommunication circuit 4 using 0.5mm ± 0.3mm flexible FPC, as shown in figure 11, wherein pad 43 and weldering
Disk 44 is respectively used to pad 41 and pad 42 on connection electrode sensor 3,4 flexible FPC of telecommunication circuit end connection letter
Number processor unit 5.In this example, telecommunication circuit 4 is than 1 long 20mm ± 5mm of support ring, and when support ring 1 deforms, flexible FPC can
Elongated with the deformation with support ring 1, to avoid damaging flexible FPC.Beautiful and clean to reach, the flexible FPC's grown is remaining
Amount is partly hidden in buffer bar 2, as shown in figure 14.In alternate embodiment, as shown in figure 12, telecommunication circuit also can edge
Buffer bar outer surface 201 to fix, the electrode sensor 3 welded thereon directly contacts with forehead.
In this example, the assembling of each part is carried out in the following manner：As shown in figure 13, respectively by 2 electrode sensors 3
2 ends insertion buffer bar 2 electrode gap in and fix, then electrode sensor is had into one end of pad and telecommunication circuit 4
On pad solder together.As shown in figure 14, telecommunication circuit 4 (flexible FPC) is placed into the cavity of buffer bar 2, cavity
It is interior to be provided with fixed lobe, and the flexible FPC grown is fixed in cavity.Finally, electrode sensor 3 will be fixed with and led to
Believe that the buffer bar 2 of circuit 4 is glued on the inboard groove of support ring 1 with environmentally friendly strength.Figure 15 is the signal that head hoop is completed
Figure.
In this example, signal processing unit 5 regards the EEG Processing module of friend's science and technology using Beijing, with telecommunication circuit 4
Connection, obtain the brain electricity bioelectrical signals that electrode sensor 3 gathers and carry out signal transacting.Figure 16 is the present embodiment intact form
Head hoop wear schematic diagram.
Above-described is only a kind of embodiment of the present utility model, it is noted that is not departing from the utility model
On the premise of principle, some modification, equivalent substitution or improvement can also be made, these should be regarded as belonging to protection of the present utility model
