Embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
Fig. 1 is the schematic diagram of the side switch fixed form of waterproof mobile terminal in prior art.
With reference to Fig. 1, according to the waterproof mobile terminal of embodiment of the present utility model, comprise fore shell 20, back cover 30 and side switch 10, side switch 10 is fitted on fore shell 20 by back cover 30.
On back cover 30, be formed with pilot hole, side switch 10 is installed to fore shell 20 through this pilot hole.Side switch 10 can comprise the outer press section 11 being formed by hard material and the elastic buffer member 12 being formed by elasticity or flexible material.Outer press section 11 is substantially in the pilot hole in back cover 30, and elastic buffer member 12 is the lower part of side switch 10, and in the processing technology of side switch 10, outer press section 11 can form by dijection injection mo(u)lding with elastic buffer member 12.The periphery of elastic buffer member 12 is formed with shirt rim 13, and this shirt rim 13 is between fore shell 20 and back cover 30, and certain strain can occur between the two in shirt rim 13 when pressing side switch 10.
On the upper surface 21 of fore shell 20, can be formed with a plurality of shrinkproof grooves 22, to prevent that fore shell 20 thickness from shrinking when excessive.As shown in Figure 1, the shirt rim 13 of side switch 10 is the top in shrinkproof groove 22 substantially, thereby is convenient to have enough deformation spaces.
In addition, also offer closed hole 23 on fore shell 2, adopt the mode of interference fit that sealing shroud 40 is installed in sealing hole 23, sealing cover 40 has certain elasticity, can be made by materials such as silica gel, to carry out water-proof function.Also between sealing shroud 40 and the closed hole 23 of fore shell 20, sealing ring 60 is set, further to improve sealing.In addition,, for the waterproof sealing at side switch 10 places, the sealing ring (not shown) that also can be aided with between fore shell 20 and back cover 30 is realized.
The downward outstanding part of the elastic buffer member 12 of side switch 10 can be inserted in sealing shroud 40, and between the lower surface 121 of elastic buffer member 12 and sealing shroud 40, conductive base 50 is installed, to carry out the transmission of power, thereby when pressing side switch 10, user triggers corresponding function.
In order to prevent that side switch 10 is anti-loaded when side switch 10 is installed,, reversed left to right, bottom at elastic buffer member 12 also can be formed with fool proof member 14, this fool proof member 14 is outstanding towards fore shell 20 from the lower surface 15 of elastic buffer member 12, and extend in one of them shrinkproof groove 22 of fore shell 20, as shown in Figure 1.
In the side switch 10 of waterproof mobile terminal provided by the utility model and the one in fore shell 20, can be formed with projection, this projection is extended towards another one, and in described another one, be formed with recessed, make projection can be fixed on this recessed in, thereby prevent that side switch 10 from departing from from fore shell 20.
In the utility model, projection can be formed on side switch 10, recessed can being formed in fore shell 20, or projection can be formed on fore shell 20, and recessed can being formed in side switch 10.Below, the projection of take is formed on fore shell 20 and recessed being formed in side switch 10 as preferred embodiment is specifically described.
Fig. 2 is according to the schematic diagram of the side switch fixed form of the waterproof mobile terminal of exemplary embodiment of the present utility model, and Fig. 3 is the vertical view of the side switch shown in Fig. 2.
With reference to Fig. 2 and Fig. 3, can be in the upper formation of upper surface 21 (upper surface 221 that the comprises shrinkproof groove 22) projection 24 of fore shell 20, this projection 24 is extended towards side switch 10.In the bottom corresponding with projection 24 of the elastic buffer member 12 of side switch 10, form recessed.Recessed size can determine according to actual installation situation, as long as can keep projection and recessed bond strength to avoid side switch 10 to come off.
Projection 24 can be formed on the upper surface in installing hole 23 outsides of fore shell 20, thus the waterproof sealing that can not interfere side switch 10 places, recessed corresponding lower surface 15 places that are formed on elastic buffer member 12.For example, projection 24 can be formed on the upper surface 221 of shrinkproof groove 22 and extend upward, and recessed can being formed in the shirt rim 13 of side switch 10.Recessed concrete form can be groove or hole, and preferably, being recessed into can be for being formed on the through hole 131 in shirt rim 13, as shown in Figure 2.
As shown in Figure 3, the cross section that is formed on the through hole 131 on shirt rim 13 is square, and now, the shape of cross section of projection 24 also can be square, or can be circle.Yet the utility model is not limited to this, mutually combine ground projection and recessed shape can arrange arbitrarily, if can secure bond together.
In addition, in the situation that projection 24 is formed in the upper surface 221 of shrinkproof groove 22, because shrinkproof groove 22 quantity on fore shell 20 are more, some shrinkproof groove 22 is not corresponding with shirt rim 13, so at this moment, recessed other positions that can be formed on elastic buffer member 12, are recessed into as long as projection 24 can be attached to this.
In addition,, the in the situation that of limited space, except the upper surface 221 of the shrinkproof groove 22 of the upper surface 21 of fore shell 20, projection 24 is other positions of upper surface 21 also.For example, can form near position closed hole 23 that is positioned at of the position of cardinal principle central authorities of upper surface 21 or upper surface 21.
In another preferred embodiment, projection also can be formed on the side surface of fore shell 20, the recessed elastic buffer member 12 that can be formed on side switch 10 in the face of on the side surface of projection 24.Can suitably arrange projection and recessed particular location, prevent from affecting the normal running of side switch 10.
It should be noted that, in above each embodiment, no matter projection and recessed position are on which parts, projection all can utilize hard material to form, and form recessed part, can utilize flexibility or elastomeric material to form, in other words, the hardness that forms the material of projection is greater than the hardness of the material that forms recessed part, with the combination between facilitating projection and being recessed into, fixes.
For example, if projection is formed on fore shell 20, projection can adopt the material identical with fore shell 20 and form with fore shell 20 so.Can adopt particularly the manufacture of dijection injection molding process.
In addition, projection and recessed between combination more, in a preferred embodiment, projection can adopt the mode of interference fit to realize fixing with recessed.In addition, also can utilize adhesive and be bonded together, as long as bond strength enough.
If adopt the combination of interference fit, the size of the cross section that is attached to the part 241 in being recessed into of projection is less than the size of recessed cross section, to increase bond strength.
In addition, projection and recessed quantity can specifically arrange according to concrete installing space situation, projection that pair of matched closes and recessed can be only set, the multipair projection matching and recessed also can be set when thering is enough spaces, to improve the installation stability of side switch.
Waterproof mobile terminal provided by the utility model, by the projection that cooperatively interacts and recessed, has improved the stability maintenance of side switch, has reduced the possibility that side switch comes off, and can not affect the water resistance at side switch place.In addition, can not increase extraly parts, contribute to save cost.
Above embodiment of the present utility model be have been described in detail; although represented and described some embodiment; but those skilled in the art should understand that; in the situation that do not depart from principle of the present utility model and the spirit that is limited its scope by claim and equivalent thereof; can modify and perfect to these embodiment, these modifications and improve also should be in protection range of the present utility model.
