Referring to Fig.1, the structure chart of novel totally-enclosed one embodiment of battery compartment of the utility model is proposed, it is described novel totally-enclosed
Battery compartment 100 includes totally-enclosed plastic pan 10, and the totally-enclosed plastic pan 10 is equipped with the thin glue region for fixing battery
20, stress relief hole 30 is equipped in the thin glue region 20.
It should be noted that the stress relief hole 30 have preset shape, in the present embodiment, with it is rectangular be it is best,
Under normal circumstances, the stress relief hole 30 and the shape of totally-enclosed plastic pan 10 are same or similar, such as totally-enclosed
Plastic pan 10 is in rectangular situation, and the stress relief hole 30 for being located at thin glue region 20 is set as rectangle, with Full-closed plastic
The shape of glue bottom case 10 is identical, thus when the thin glue region 20 of totally-enclosed battery compartment forms because with totally-enclosed plastic pan 10
Shape it is identical, guarantee molding when thin glue region 20 stress equalization.
Internal stress force diagram when existing totally-enclosed plastic pan as shown in Figure 2 forms.
Carry out totally-enclosed plastic pan 10 molding when, stress concentration in the center in thin glue region 20, thus due to
The reason of stress, stress concentration region 60, which has been easy to appear, bulging or recessed etc. to cause to deform.
The direction of arrow is expressed as the direction of internal stress in figure, by figure it is found that totally-enclosed plastic pan 10 form when
Internal stress is mainly concentrated to the center in thin glue region 20, to cause discontinuity equalization, center by interior due to being answered
Deformation is easily caused under the action of power.
The structural schematic diagram of existing totally-enclosed plastic pan deformation as shown in Figure 3.
Deformed in the molding of totally-enclosed plastic pan 10, above battery compartment increased thin glue region 20 because of glue position too
Thin and plastic cement autogenous shrinkage rate influence causes battery compartment top middle position internal stress after molding excessive, and arch or recessed
Seriously, arch area 70 or recessed area 80 in appearance, under normal circumstances, big shape changeable is in 1mm or more, and product is normal
Degree of deformation is required in 0.25 ± 0.05mm or so.
The structural schematic diagram of existing totally-enclosed plastic pan as shown in Figure 4 causes electricity since thin glue position is pushed up to battery
The security risk and battery in pond build drum, while the rubberizing face NFC injustice being made to be not easy to paste, and NFC is jacked up and done with battery cover
It relates to and influences the factors such as NFC performance, now in production generally can be by adjusting localized mode temperature, firing rate or dwell time etc. are because usually
Optimization improves arch camber, but improved space is very limited, and need to spend a large amount of tune machine die trial time that structure function is not achieved again
With the requirement of quality, the production time is given, production cost and product quality are affected and lost.Mold high temperature water route in such as figure
90, in the molding of totally-enclosed plastic pan 10, since localized mode temperature increases, product surface temperature is increased, and is shunk and is accelerated, thus compared with
Small convex table deformation.
The phenomenon that being deformed when in order to reduce molding, the totally-enclosed plastic pan 10 with stress relief hole as shown in Figure 5
Internal stress force diagram when molding.
The direction of arrow is expressed as the direction of internal stress in figure, by figure it is found that in the full envelope with stress relief hole 30
Internal stress when plastic pan 10 forms is closed to answer in original mainly from the center in thin glue region 20 to external diffusion to change
The Impact direction of power changes product shrinkage direction by stress relief hole 30, draws due to central reduction after reducing formed product
The stress concentration risen leads to local deformation of arching upward, the phenomenon that being easily deformed in molding so as to improve thin glue region 20.
The stress relief hole 30 is located at the center in the thin glue region 20.It should be noted that described answer
The position that power relief hole 30 is located at the thin glue region 20 can also be other positions, and the present embodiment is not intended to limit this, but
The center in thin glue region 20 be it is best, due to totally-enclosed plastic pan 10 molding when internal stress mainly from thin glue region 20
Center, so that stress relief hole 30 be located to the center in the thin glue region 20, to change the collection of internal stress
Middle Impact direction, the phenomenon that being easily deformed when can effectively reduce the molding of totally-enclosed plastic pan 10.
The stress relief hole 30 has preset shape.
When the stress relief hole 30 is rectangular, the length of the stress relief hole 30 is 15-28mm, width 6-
15mm。
The scale diagrams of stress relief hole as shown in FIG. 6.
Wherein, a indicates the length of the stress relief hole 30 in figure, and b identifies the width of the stress relief hole 30, described
Stress relief hole 30 can be via design, to be more conducive to change the Impact direction of internal stress.It applies in 4.7 inch display screens
For the length of the totally-enclosed plastic pan 10 of mobile phone in 15-18mm, width applies the mobile phone in 5.0 inch display screens in 6-8mm
For the length of totally-enclosed plastic pan 10 in 18-20mm, width applies the full envelope in the mobile phone of 5.5 inch display screens in 8-10mm
The length of plastic pan 10 is closed in 20-25mm, width applies the Full-closed plastic in the mobile phone of 6.0 inch display screens in 10-12mm
The length of glue bottom case 10 is in 25-28mm, and width is in 12-15mm, so as to meet the application demand of different size mobile phones.
In order to effectively change the direction of the internal stress in the molding of totally-enclosed plastic pan 10, correspond to stress relief hole
It is 67-78mm that the size of the 30 totally-enclosed plastic pan 10, which is width, the glue position thickness of the novel totally-enclosed battery compartment
Within 0.4-0.6mm.By giving the totally-enclosed thin glue battery compartment of bottom case, center increases a stress relief hole 30, thus
The contraction ratio and shrinkage direction of thin glue position are effectively reduced, so that the deformation of the thin glue position of totally-enclosed battery compartment is improved,
Top battery and top NFC risk are deformed to thin glue, play prevention improvement result.
Novel totally-enclosed battery compartment provided in this embodiment includes totally-enclosed plastic pan 10, the totally-enclosed plastic pan
10 are equipped with the thin glue region 20 for fixing battery, stress relief hole 30 are equipped in the thin glue region 20, by described thin
Glue region 20 is equipped with stress relief hole 30, thus bulging or recessed technical problem from when reducing thin glue position molding above battery compartment.
In addition, the utility model also proposes that a kind of mobile phone 200, the mobile phone 200 include novel full envelope as described above
Battery compartment 100 is closed, the mobile phone further includes the battery and low coverage for being fixed on the novel totally-enclosed thin glue region 20 of battery compartment
From wireless communication device, the near field communication device fits in the battery surface.
The structural schematic diagram of mobile phone as shown in Figure 7, the mobile phone 200 include novel totally-enclosed battery as described above
Storehouse 100 further includes the battery 40 and wireless near field communication dress for being fixed on the novel totally-enclosed thin glue region 20 of battery compartment
50 are set, the near field communication device 50 fits in 40 surface of battery.
The above is only the preferred embodiments of the utility model, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
