Solution is limitation of the present invention.
Referring to Figure 1 to Fig. 4, mobile terminal 100 includes graphite flake mounting structure 1 and device 2, graphite flake mounting structure 1
Including graphite flake 11 and bond 12, the bond 12 includes several colloids 121, several described colloids 121 are adhered to
On the graphite flake 11, the two neighboring interval of colloid 121 setting forms groove 122, and the graphite flake 11 is through the bonding
Part 12 is adhered on the device 2, and after the bond 12 is squeezed, several described 121 overflows of colloid enter the groove
In 122, so that the groove 122 fills the full colloid 121.
By the way that several colloids 121 are arranged on graphite flake 11, and the interval of two neighboring colloid 121 forms groove 122, makes
Graphite flake 11 when being bonded on device 2 through bond 12, due to there is the presence of groove 122, in bond 12 colloid 121 to
When groove 122 is filled, the bubble that bonding process generates can also reach then to be discharged in groove 122, can effectively reduce bubble,
To guarantee that graphite flake 11 and device 2 have preferable cementability.
In one embodiment, referring to figure 2., graphite flake 11 has the bonding plane 11a and back side 11b being disposed opposite to each other, bonding plane
Bond 12 is arranged so that graphite flake 11 to be adhered on device 2 in 11a.Graphite flake 11 is rectangular configuration, corresponding graphite flake 11
Bonding plane 11a is square surface.Certainly, in other embodiments, graphite flake 11 can be such as trapezoidal, round with other shapes
Deng.
In one embodiment, referring to figure 3. and Fig. 4, several colloids 121 of bond 12 are arranged in the bonding of graphite flake 11
On the 11a of face, graphite flake 11 is adhered on device 2 through several colloids 121, in the bonding process of graphite flake 11 and device 2, if
Dry colloid 121 is moved closer to and is extruded, effect of several colloids 121 in extruding force with graphite flake 11 and device 2
Under, it can be flowed towards the direction of groove 122, and during this, the bubble of several colloids 121 can also be moved to groove 122
In, due in groove 122 there is colloid 121 to flow, the bubble being moved in groove 122 also can be with the flowing of colloid 121
And be discharged among graphite flake 11 and device 2, so as to effectively reduce the gas generated during graphite flake 11 and the fitting of device 2
Bubble, and then guarantee that graphite flake 11 and device 2 have preferable cementability.
It should be understood that referring to figure 3. and Fig. 4, the edge of the bond 12 is adjacent to the edge of the graphite flake 11.Tool
Body, several colloids 121 form rectangle identical with bonding plane 11a shape, and the area of the rectangle is slightly less than bonding plane
The area of 11a, the i.e. edge of bond 12 and the edge of bonding plane 11a are there are at a distance from 0.5mm~1mm, so that bond 12
When being squeezed flowing, most of colloid 121 is avoided to overflow from the edge of bonding plane 11a.
In one embodiment, referring to figure 3., the colloid 121 is in rectangle, and each 121 structure of colloid is identical.Specifically
, the identical colloid 121 of several shape sizes is arranged on the bonding plane 11a of graphite flake 11.It sets each colloid 121 to
The identical structure of structure, conducive to the size of the spacing between the arrangement and control colloid 121 of several colloids 121.Certainly, at it

The length direction Y and width direction X of ink sheet 11 are arranged, and the groove 122 to be formed so then is made to be located at the length side of graphite flake 11
To Y and width direction X, so that bubble can be discharged in the length direction Y and width direction X of graphite flake 11.
In one embodiment, referring to figure 3., a part of groove 122 along the graphite flake 11 extending direction successively
Perforation, another part groove 122 are successively penetrated through along the width direction X of the graphite flake 11.Specifically, several colloids
121 along graphite flake 11 length direction Y and width direction X proper alignment so that in the ditch of 11 length direction Y of graphite flake
Slot 122 successively penetrates through, it is possible to understand that, groove 122 is strip.Fall into length direction Y (or the width direction of graphite flake 11
X groove 122) can be moved to the edge of graphite flake 11 and be discharged, to be further reduced the generation of bubble, stone is effectively ensured
The adhesive property of ink sheet 11 and device 2.
When mobile terminal 100 provided in an embodiment of the present invention starts attachment, set on the bonding plane 11a of graphite flake 11 first
Set several colloids 121, be then pasted on graphite flake 11 on device 2 through several colloids 121, several colloids 121 with
Graphite flake 11 and device 2 are moved closer to and are extruded, several colloids 121, can be towards groove 122 under the action of extruding force
Direction flowing, and during this, the bubble of several colloids 121 can be also moved in groove 122, due in groove 122
It is being flowed with colloid 121, also 11 He of graphite flake can be discharged with the flowing of colloid 121 in the bubble being moved in groove 122
Among device 2, so as to effectively reduce the bubble generated during graphite flake 11 and the fitting of device 2, and then guarantee graphite flake
11 have preferable cementability with device 2.
If graphite flake mounting structure 1 provided in an embodiment of the present invention and mobile terminal 100 on graphite flake 11 by being arranged
Dry colloid 121, and the interval of two neighboring colloid 121 forms groove 122, so that graphite flake 11 is bonded in device through bond 12
When on 2, due to there is the presence of groove 122, colloid 121 to groove 122 when filling in bond 12, the gas of bonding process generation
Bubble can also be reached and is then discharged in groove 122, can effectively reduce bubble, thus guarantee graphite flake 11 and device 2 have compared with
Good cementability.
