In order to make those skilled in the art more fully understand application scheme, below in conjunction in the embodiment of the present application
Attached drawing, the technical scheme in the embodiment of the application is clearly and completely described.Obviously, described embodiment is only
Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those skilled in the art are not having
Every other embodiment obtained under the premise of creative work is made, shall fall in the protection scope of this application.
First embodiment
FIG. 1 to FIG. 4 is please referred to, the housing unit 100 that the application first embodiment provides includes shell 10 and waterproof convex ribs
20, the housing parts of mobile terminal are formed suitable for being assembled together with metal shell 60.Housing unit 100 and metal shell 60
Assembly method can be glued, buckle and combine etc..
Shell 10 includes positioned at the plastic layer 101 of 10 periphery of shell and positioned at 10 inside of shell and and 101 phase of plastic layer
The alloy-layer 102 of fitting.It should be understood that in the present embodiment, " periphery " and " inside " phase of shell 10 of shell 10
It is corresponding, it is the peripheral wall portions of shell 10.Specifically, plastic layer 101 and alloy-layer 102 are collectively formed shell 10, and shell
Body 10 has inner space, and the periphery of shell 10 is then shell 10 away from the part of the inner space and/or surface and/or edge
The circumferentially extending of shell 10/circular peripheral wall portions.
Shell 10 include outer end face 12, outer end face 12 include seam allowance side wall 121 and be connected with seam allowance side wall 121 first
Mating surface 122, the first mating surface 122 include the outer end face of plastic layer 101, also include the outer end face of alloy-layer 102.
Seam allowance side wall 121 refers to a die joint of injecting products, the cooperation often matched with other fit structures
Face.
Waterproof convex ribs 20 are formed in seam allowance side wall 13 by quadric injection mould (also referred to as double-shot moulding) molding mode, that is,
Waterproof convex ribs 20 and plastic layer 101 are double-shot moulding integral structure.Waterproof convex ribs 20 can use TPU (Thermoplastic
Polyurethanes, thermoplastic polyurethane elastomer rubber) material manufacture, therefore, waterproof convex ribs 20 are rendered as the shape of rubber ring
Formula, with good bearing capacity and impact resistance.Waterproof convex ribs 20 are projected on its attachment surface, in the present embodiment, waterproof
Convex ribs 20 are projected on seam allowance side wall 121, and waterproof convex ribs 20 include top 201, and top 201 includes vertex A.Top 201 be used for
Metal shell 60 offsets.In the present embodiment, top 201 is set to one end that waterproof convex ribs 20 deviate from seam allowance side wall 121,
The surface on top 201 is curved surface so that the surface on top 201 is smooth continuous, make top 201 and metal shell 60 in assembly more
It is smooth.Further, top 201 is part spherical structure, and cross-sectional profiles are circular arc.In other embodiments, prevent
The section of water convex ribs 20 can be other shapes, such as triangle, rectangle, irregular shape etc..
Metal shell 60 is covered on shell 10 comprising the second mating surface 62 matched with seam allowance side wall 121 works as shell
10 with metal shell 60 when fitting together, and 121 second mating surface 62 of seam allowance side wall is opposite, passes through assembly force squeezing from the outside to the core
Pressure, waterproof convex ribs 20 and metal shell 60 are interference fitted, specifically, the of the tops 201 of waterproof convex ribs 20 and metal shell 60
Two mating surfaces 62 are offseted and then are pressed together tightly, and are formed an airtightness waterproof construction, are avoided in shell 10 and metal
There are gaps between shell 60, therefore liquid can not enter housing unit from cooperation place of waterproof convex ribs 20 and metal shell 60
100 inside.
Since seam allowance side wall 121 is close to the outer rim of entire plastic layer 101, can give when water just enters shell 10
Stop, rather than waterproof is carried out by setting foam sealing element in the position inside housing unit, therefore, the present embodiment mentions
The waterproof performance of the housing unit 100 of confession greatly improves.
In order to reinforce waterproofness, waterproof convex ribs 20 were arranged around shell 10 1 weeks, thus with the interference everywhere of metal shell 60
Cooperation.
Further, in some embodiments, metal shell includes side wall 601 and bottom wall 603, and side wall 601 connects
In bottom wall 603, simultaneously opposing bottom wall 603 is bent, and an accommodating space is collectively formed in side wall 601 and bottom wall 603, and shell 10 is partly received
It is dissolved in the accommodating space；Outer end face 12 and side wall 601 are opposite, and waterproof convex ribs 50 and side wall 601 are interference fitted.At this point, waterproof
Protrusion direction of the convex ribs 50 relative to outer end face 12 are as follows: extend from outer end face 12 towards side wall 601, that is, waterproof convex ribs 20 are horizontal
The width direction that the extending direction in section moves along terminal 400 (hereafter addressing) extends, and does not need to occupy mobile terminal
The space of 400 thickness direction is conducive to the slimming design of mobile terminal 400.Meanwhile waterproof convex ribs 20 are set to side wall
In 601, it is interference fitted using assembly preset between original shell 10 and metal shell 60 gap, is also hardly needed
The space of 400 width direction of mobile terminal is occupied, does not need additional bonded structure more, is conducive to the narrow side of mobile terminal 400
Frame design.
In the present embodiment, plastic layer 101 includes outer edge 1011, and outer edge 1011 protrudes from seam allowance side wall 121, and only
The position that mouth side wall 121 connects forms the turning close to right angle.Outer edge 1011 is relative to the plane where seam allowance side wall 121
Including a distalmost end B, the vertex A on top 201 is concordant with distalmost end B.
In other embodiments, vertex A can also than distalmost end B closer to seam allowance side wall 121, i.e. waterproof convex ribs 20 most
Far extend to concordant with distalmost end B, the size of such waterproof convex ribs 20 is suitable, can both guarantee waterproof convex ribs 20 and gold
Belong to shell 60 can be interference fitted, be also unlikely to make between shell 10 and metal shell 60 because waterproof convex ribs 20 and there are larger
Gap.
Metal shell 60 further includes the third mating surface 63 being connected with the second mating surface 62.Third mating surface 63 and first
Mating surface 122 is moved towards with the structure of metal shell 60 and shell 10 and changes the extending direction of each part, the two phase always
To setting.
In the present embodiment, there are gaps between third mating surface 63 and the first mating surface 122.
To sum up, housing unit 100 provided in this embodiment is provided with waterproof convex ribs 20 in the seam allowance side wall 121 of shell 10,
Waterproof convex ribs 20 can form interference fit with other assembling structures to improve sealing performance.
