BACKGROUND
[0002] 1. Technical Field
[0003] The present disclosure relates generally to device housings
and, more particularly, to a device housing for an electronic
devices.
[0004] 2. Description of Related Art
[0005] With developments in technology, electronic devices such as
mobile phones are not only required to perform many functions, but
also provide an appearance appealing to the user.
[0006] Referring to FIGS. 9 and 10, a frequently used housing 10
for a mobile phone includes a frame 11 and a glass plate 12
received therein. The frame 11 is substantially rectangular, and
forms a positioning portion 113 on an inner surface. During
assembly of the device housing 10, the adhesive 20 is coated on the
positioning portion 113. The glass plate 12 is received in the
frame 11, and attached to the positioning portion 113. Thus, the
glass plate 12 and the frame 11 are glued together. The adhesive 20
is generally epoxy resin glue, which can only be used once.
[0007] However, a gap may form between the glass plate 12 and the
frame 11, out of which the adhesive 20 may overflow, affecting
appearance. Furthermore, the adhesive 20 may not uniformly cover
the positioning portion 113, such that a top surface of the glass
plate 12 may misalign with a top surface of the frame 11. The
appearance of the device housing 10 is again affected.
[0008] Therefore, a device housing overcoming the described
limitations is desirable.

DETAILED DESCRIPTION
[0020] Referring to FIGS. 1 through 3, a first embodiment of a
device housing 30 is integrally formed by a plastic frame 31, a
glass plate 33, and an adhesive member 35. In the illustrated
embodiment, the device housing 30 is used for an electronic device
(not shown).
[0021] The plastic frame 31 includes a side frame 311 and an
annular positioning portion 312 formed on an inner surface of the
side frame 311. The plastic frame 31 can be formed by molding (not
shown). In the illustrated embodiment, the side frame 311 is
substantially rectangular. The plastic frame 31 is comprised of
nylon and fiberglass.
[0022] The glass plate 33 includes a first surface 331, a second
surface 332 opposite to the first surface 331, and a side surface
333 connecting the first surface 331 with the second surface 332. A
periphery of the first surface 331 is coated with printing ink to
form a light shielding portion 335 and a light guiding portion 336
surrounded by the light shielding portion 335. An end of the glass
plate 33 defines three assembly holes 337 arranged side by side. A
chamfer angle 338 is formed on an edge of the first surface 331 and
the second surface 332 to enhance structural integrity of the glass
plate 33. In the illustrated embodiment, the glass plate 33 is
substantially rectangular.
[0023] The adhesive member 35 is polyurethane glue in this
embodiment. The polyurethane glue can be liquefied to provide
adhesion in damp and high temperature conditions (exceeding about
60 degrees Celcius), and solidified to provide adhesion in dry and
normal temperature conditions. Thus, the adhesive member 35 can be
used repeatedly. In the illustrated embodiment, the adhesive member
35 is substantially a rectangular ring corresponding to the
positioning portion 312 of the plastic frame 31.
[0024] The device housing 30 can be integrally formed by molding as
follows: printing the adhesive member 35 on the edge of the glass
plate 33 and drying the adhesive member 35; positioning the glass
plate 33 in the injection mold; injecting melted plastic material
to the side surface 333 of the glass plate 33 to form the plastic
frame 31, and the adhesive member 35 generating adhesion in damp
and high temperature conditions; cooling the device housing 30 and
the plastic frame 31 contacting the glass plate 33 with no gap,
with the adhesive member 35 sandwiched between the plastic frame 31
and the glass plate 33 to enhance connection strength
therebetween.
[0025] Since the plastic frame 31 and the glass plate 33 are
integrally formed via the injection mold, no gap is formed
therebetween and a top surface of the glass plate 33 can align with
a top surface of the plastic frame 31. Thus, the device housing 30
presents an unspoiled appearance. In addition, the adhesive member
35 is printed on the glass plate 33 and the device housing 30 is
integrally formed, thus manufacturing efficiency is greatly
improved.
[0026] It should be pointed out that the plastic frame 31 and the
glass plate 33 may be other shapes, for example, the glass plate 33
may be an ellipse, and the plastic frame 31 an ellipsular ring. In
addition, the chamfer angle 338 may be formed on an edge of the
first surface 331 or the second surface 332.
[0027] Referring to FIGS. 4 through 6, a second embodiment of a
device housing 50 is integrally formed by a plastic frame 51, a
glass plate 53, an adhesive member 55, and a plurality of fastening
members 57. The plastic frame 51, the glass plate 53, and the
adhesive member 55 have a similar structure to the first embodiment
of the plastic frame 31, the glass plate 33, and the adhesive
member 35 of the device housing 30 respectively.
[0028] Each fastening member 57 includes a main body 571 and a hook
portion 573 extending from an end of the main body 571. Each
fastening member 57 defines one or more connecting holes 575. The
one or more connecting holes 575 is configured for allowing molten
plastic material therethrough in an injection process. The
connecting holes 575 are filled with plastic material after the
melted plastic material cools.
[0029] The device housing 50 can be integrally formed by molding as
follows: printing the adhesive member 55 on the edge of the glass
plate 53 and drying the adhesive member 55; positioning the glass
plate 53 and the fastening members 57 in the injection mold, the
fastening members 57 corresponding to the edge of the glass plate
53, and the hook portion 573 attached to the adhesive member 55;
injecting melted plastic material to the side surface 533 of the
glass plate 53 and the fastening members 57 to form the plastic
frame 51, and the adhesive member 55 generating adhesion in damp
and high temperature conditions; cooling the device housing 30,
with the plastic frame 31 connecting the glass plate 33 and the
fastening members 57 with no gap, and the adhesive member 35
sandwiched between the plastic frame 31, the glass plate 33, and
the fastening members 57 to enhance a connecting strength
therebetween. The device housing 50 also presents an unspoiled
appearance, and is easily manufactured. The fastening members 57
can engage other components of the electronic device.
[0030] In an alternative embodiment, the fastening members 57 can
be positioned in the injection mold with a certain distance between
the adhesive member 55 and the fastening members 57.
[0031] Referring to FIG. 7, a third embodiment of a device housing
70 is integrally formed by a plastic frame 71, a glass plate 73, an
adhesive member 75, and a plurality of fastening members 77. The
device housing 70 differs from the device housing 50 of the second
embodiment only in that the glass plate 73 defines an annular
receiving groove 735 on an edge of a second surface 732. The
adhesive member 75 is received in the receiving groove 735. A
thickness of the device housing 70 can be less than that of the
device housing 50 because the adhesive member 75 is received in the
receiving groove 735. Alternatively, the glass plate 73 can define
the receiving groove 735 in the side surface.
[0032] Referring to FIG. 8, a fourth embodiment of a device housing
90 is integrally formed by a plastic frame 91, a glass plate 93, an
adhesive member 975, and a plurality of fastening members 97. The
device housing 90 differs from the device housing 50 of the second
embodiment only in that the glass plate 93 forms a connecting
surface 935 on an edge of a first surface 931. The plastic frame 91
forms a connecting portion 919 on the connecting surface 935. In
the illustrated embodiment, the connecting surface 935 is angled.
Structural integrity of the device housing 90 is better than that
of housing 50 of the second embodiment because the plastic frame 91
has a connecting portion 919 positioned on the connecting surface
935 of the glass plate 93.
[0033] It is believed that the present embodiments and their
advantages will be understood from the foregoing description, and
it will be apparent that various changes may be made thereto
without departing from the spirit and scope of the disclosure or
sacrificing all of its material advantages.
