Abstract
The utility model relates to a waterproof structure and an electronic device with the same. The waterproof structure comprises a housing and a cover. The cover is assembled on the housing. The housing is provided with a groove. The cover comprises a projected bone position and a flexible material structure. The flexible material structure coats the projected bone position and is formed integrally with the projected bone position. The flexible material structure is in interference fit with the groove. Because of arrangement of the projected bone position, when the flexible material structure is in interference fit with the groove, supporting of the projected bone position can make the flexible material deform reliably, thereby realizing a good waterproof effect. Simultaneously, the flexible material structure and the cover are formed integrally, and additional assembling of waterproof soft glue is not required. Consideration of the waterproof soft glue in setting an interference amount is not required. Therefore good waterproof performance can be realized through a smaller interference amount, thereby reducing requirement for structure strength of a battery cover. The utility model further relates to an electronic device with the waterproof structure provided by the utility model, such as a mobile phone. Besides better waterproof effect, the electronic device has advantages of assembling step reduction and production efficiency increase.
Description
Technical field
The utility model relates to a kind of waterproof construction, and a kind of electronic installation that uses this waterproof construction.
Background technology
In recent years, along with the increase of people's outdoor activities, various waterproof electronic devices emerged in an endless stream, and in the waterproof link of this type of electronic installation, the waterproof of battery cover is technological difficulties all the time.In prior art, battery cover waterproof mostly adopts side pressure waterproof type, please refer to Fig. 1 and Fig. 2, described electronic installation waterproof construction comprises a back cover 100, one battery cover flexible glue 200 and a battery cover 300, described back cover 100 comprises a plane 101 side vertical with described plane with one 102, described plane 101 and side 102 connect into " L " shape, on described battery cover 300, correspondence comprises the side 302 that a plane 301 is vertical with described plane 301 with, described plane 301 and side 302 connect into handstand " L " shape, described battery cover 300 is assembled on back cover 100, described plane 101 is relative with plane 301, described side 102 is relative with side 302, a rectangle clearance spaces of common formation, described battery cover flexible glue 200 is fixed in described plane 301, as adopt gum to paste, and be filled in described rectangle clearance spaces, described two sides 102, the described battery cover flexible glue 200 of 302 extruding forms interference fit 400 and carries out waterproof.In above-mentioned waterproof construction, the independent processing and manufacturing of battery cover waterproof flexible glue 200, in the time that battery cover waterproof flexible glue 200 is fixed on battery cover 300, need special assembling station, simultaneously, adopt the fixing packaging technology operational consistency of stickup poor, there is larger assembling deviation, and be difficult to guarantee that assembling puts in place, separately please refer to Fig. 3, A is described back cover side 102 interplanar distances, B is described battery cap lateral 302 interplanar distances, the accuracy of manufacture of A and B directly affects the interference waterproof of battery cover flexible glue 200, and due to A and B size larger, tolerance is difficult to control, thereby strengthen the manufacture difficulty of battery cover 300 and housing 100, simultaneously for battery cover flexible glue 200, the manufacturing tolerance of itself adds that assembling deviation causes interference fit deflection everywhere inconsistent, reach reliable waterproof effect, need to strengthen the magnitude of interference, the larger magnitude of interference has higher requirement to back cover 100 and the structural strength of battery cover 300, thereby need to structurally gain in strength design, must have influence on the design size of back cover 100 and battery cover 300 entirety, in addition, side pressure interference waterproof type of the prior art, its waterproof effect depends on the pressure force of 102,302 pairs of battery cover flexible glues 200 of described two planes completely, under same pressure force effect, inconsistent according to above analysis battery cover flexible glue 200 interference fit deflection everywhere, therefore waterproof effect is poor, in addition, because back cover 100, a battery cover flexible glue 200 and a battery cover 300 are manufactured and are assembled respectively, need consideration back cover 100 and battery cover flexible glue 200 and battery cover flexible glue 200 and 300 liang of battery covers to locate the sealing of anti-water level, increased waterproof difficulty.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of waterproof construction, and described waterproof construction can reduce assembling procedure, reduces simultaneously the structural strength of lid is required and accuracy of manufacture requirement, realizes good waterproof effect.
Another technical problem to be solved in the utility model is, a kind of electronic installation that uses above-mentioned waterproof construction is provided, and this electronic installation can be realized sealed waterproof effect good between lid and housing, simplifies assembling procedure, improving production efficiency simultaneously.
A kind of waterproof construction, it comprises a housing and a lid, described lid is assembled on housing, one groove is set on described housing, described lid comprises a protruding position of bone and a flexible material structure, described flexible material structure is coated the described protruding position of bone, and one-body molded with the described protruding position of bone, described flexible material structure and described groove interference fit.
A kind of electronic installation, uses above-mentioned waterproof construction.
The beneficial effect that the utility model produces is: because described lid is provided with the protruding position of bone, described flexible material structure is coated the described protruding position of bone, and one-body molded with the described protruding position of bone, described flexible material structure and described groove interference fit, in this structure, due to the setting of the described protruding position of bone, in the time that described flexible material structure and described groove interference fit are subject to lateral pressure, stop and can make described flexible material distortion reliably by the support of the described protruding position of bone, realize good waterproof effect, simultaneously, described flexible material structure and described lid are one-body molded, without the assembling of carrying out battery cover waterproof flexible glue in prior art, reduce flow chart, packaging efficiency and yield are promoted, and without the sealing between waterproof flexible glue and lid in consideration prior art, reduce anti-water level, promoted waterproof reliability, in addition, the utility model flexible material structure and lid are one-body molded and be assembled in housing groove, its waterproof reliability only depends on the described protruding position of bone and the integrated manufacturing tolerance of described flexible material structure, compare A and B described in prior art, because the size of the described position of bone and described flexible material and described groove is less, tolerance is easy to guarantee, reduce the manufacture difficulty of housing and battery cover, there is no the assembling deviation of battery cover waterproof flexible glue in prior art simultaneously, thereby cumulative limit is relatively little, design the good result that the less magnitude of interference can meet water-tight, reduce the structural strength requirement to battery cover.
