Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1 to Fig. 2 is referred to, the invention provides a kind of housing unit 100, the housing unit 100 includes first shell
Body 10 and the second housing 20 for being fixed on first housing 10, first housing 10 have positioning hole 11, the second shell
Body 20 has the locating piece 21 being engaged with the positioning hole 11, and the week side of boss of the locating piece 21 is provided with deformation projection 30, described
Deformation projection 30 is extruded by the madial wall of the positioning hole 11 and produces deformation, and closely contacts at the interior of the positioning hole 11
Side wall, to coordinate the tolerance clearance between the locating piece 21 and the positioning hole 11.It is understood that the housing unit
100 are used in the equipment of mobile terminal 200, and the equipment of mobile terminal 200 can be mobile phone, tablet personal computer, notebook computer, electronics
The electronic equipment such as book reader and music player.
In the present embodiment, first housing 10 has the first assembling side wall 101, the locating piece 21 to described the
One assembling side wall 101 has the first location dimension, and second housing 20 has the second assembling side wall 201, the positioning hole 11
There is the second location dimension to the described second assembling side wall 201, the deformation projection 30 is to be adapted to first location dimension
And the difference of second location dimension.It is described because first housing 10 is different with the manufacture of second housing 20
The form and position tolerance of first housing 10 and second housing 20 is also differed, i.e., described first location dimension and second positioning
The numerical value of size is simultaneously differed, between the two in the presence of a difference.When first location dimension is more than second positioning rule
When very little, the locating piece 21 coordinates with the positioning hole 11, the first assembling side wall 101 and the described second assembling side wall 201
Between gap occurs；When first location dimension be less than second location dimension when, the locating piece 21 with it is described fixed
When position hole 11 coordinates, excessive interference occurs between the first assembling side wall 101 and the second assembling side wall 201；It is based on
This, sets deformation projection 30 between the locating piece 21 and the positioning hole 11, to be adapted to first location dimension with
The difference of second location dimension.Wherein, deformation projection 30 is by elastomeric material, plastic material or other force-applied generation deformation
Material be made, deformation projection 30 interference be arranged between the locating piece 21 and the positioning hole 11, the deformation projection 30
Deformation can be produced due to stress, the deformation of the deformation projection 30 drives second housing 20 to close to first housing 10
Direction is moved, so ensure the reasonable fit clearance between first housing 10 and second housing 20.It is excellent as one kind
The embodiment of choosing, the positioning hole 11 is rectangular opening, and the locating piece 21 is rectangular cam, and the deformation projection 30 is fixedly arranged on
The week side of boss of rectangular cam, the deformation projection 30 is extruded by rectangular opening madial wall and produces deformation, and then rectangular cam drives
Second housing 20 is moved to close to the direction of the first housing 10.In other embodiments, first housing 10 is set
The locating piece 21 is put, second housing 20 sets the positioning hole 11, and the deformation projection 30 can also be fixedly arranged on described
The week side of boss of positioning hole 11, the deformation projection 30 is extruded by the lateral wall of locating piece 21 and produces deformation, and the deformation is convex
30 are played in order to reply deformation, applies a restoring force close to second housing 20 to the locating piece 21, it is basic to reach
Identical technique effect.
The housing unit of the present invention, by setting deformation raised in the locating piece the week side of boss, the deformation it is raised with it is described
Positioning hole madial wall is closely contradicted, and the deformation is raised to be produced deformation by positioning hole madial wall extruding, to be adapted to
The tolerance clearance between locating piece and the positioning hole is stated, and then ensures the conjunction between first housing and second housing
Fit clearance is managed, the appearance property of housing unit is improved.
Further, first housing 10 also has the cushion hole 12 adjacent with the positioning hole 11, the positioning hole
It is spaced between 11 and the cushion hole 12 by dividing plate 40, the deformation projection 30 contacts at the dividing plate 40, the buffering
Hole 12 is that the dividing plate 40 provides deformation space, to reduce the structural stress of the dividing plate 40.
Fig. 3 to Fig. 4 is referred to, in the present embodiment, in order to prevent the deflection for reducing the deformation projection 30, is prevented
The deformation projection 30 produces big plastic deformation, or even occurs being collapsed shearing situation, in the adjacent position of positioning hole 11
The cushion hole 12 is opened up, dividing plate 40 is set between the positioning hole 11 and the cushion hole 12, the dividing plate 40 can be along described
The direction of cushion hole 12 produces slight deformation, to reduce indirectly at the deformation projection 30 and the madial wall conflict of positioning hole 11
Contact strength.As a kind of preferably embodiment, the cushion hole 12 is rectangular opening, the cushion hole 12 and the deformation
Raised 30 protrusion directions are parallel to each other, i.e., described cushion hole 12 is located at the side of the vertical direction of positioning hole 11.It is described
The dividing plate 40 is formed between cushion hole 12 and the positioning hole 11, the deformation projection 30 is not supported directly with the dividing plate 40
Touch, but contacted by the side wall of locating piece 21 with the dividing plate 40, when in deformation projection 30 and the positioning hole 11
When side wall is contradicted, triangular shape is shaped as due to the deformation projection 30, one can be produced the side wall of locating piece 21 is squeezed
The component of the dividing plate 40 is pressed, and then the contact reduced between the deformation projection 30 and the madial wall of positioning hole 11 should
Power.Fig. 4 is referred to, as a preferred embodiment, the cushion hole 12 is dimensioned slightly smaller than the positioning hole 11, it is described
