DETAILED DESCRIPTION
Please refer to FIG. 3. FIG. 3 is a diagram of a mobile phone 50
according to the present invention. A mobile phone 50 comprises
a housing 51, a side button 52, a battery 54, a lower case 56, an
elastic member 58, and a circuit board 60. The circuit board 60
is installed in the housing 51, and a control circuit (not shown)
on the circuit board 60 can control the operation of the mobile
phone 50. The side button 52 is installed on the housing 51 in a
slidable manner for producing a control signal when it is pressed.
The battery 54 is installed in the housing 51 for supplying power
to the mobile phone 50. The elastic member 58, in which one end
is fixed to the housing 51 and the other end is connected to the
side button 52, can be a spring.
Please refer to FIG. 3 in conjunction with FIG. 4. FIG. 4 is a
diagram of the battery 54 depicted in the FIG. 3. The mobile phone
50 further comprises a connector 68. The side button 52 comprises
a monolithic engaging hook 66, which moves along with the side button
52. The battery 54 has a recess 64 and a plurality of fixing hooks
78 in its housing, the recess 64 can be a groove or a dimple for
accommodating the engaging hook 66 of the side button 52 to fix
the battery 52 on the housing 51. The lower case 56 is installed
between the battery 54 and the circuit board 60 to separate the
battery 54 and the circuit board 60. The lower case 56 includes
an opening 72 and a plurality of engaging sinks 74 to engage a plurality
of fixing hooks 78 of the battery 54 to strengthen the integration
between the battery 54 and the lower case 56. In another preferred
embodiment, however, the lower case 56 does not necessarily require
engaging sinks 74, and the battery 54 does not necessarily have
fixing hooks 78 as well, the engaging hook 66 of the side button
52 and the recess 64 of the battery 54 can fix the battery 54 on
the housing effectively.
The manner of installing the battery 54 on the housing 51 of the
mobile phone 50 is introduced as follows. Please refer to FIG. 3
in conjunction with FIG. 5 and FIG. 6. FIG. 5 and FIG. 6 show the
relative position of the side button 52 and the elastic member 58
when installing the battery 54. From FIG. 3, the lower case 56 must
be installed on the housing 51 to separate the battery 54 and the
circuit board 60. The engaging hook 66 can protrude out of an opening
72 of the lower case 56. In order to depict the process of installing
the battery 54 on the housing 51 of the mobile phone 50, the battery
54 and the lower case 56 are not shown in FIG. 5 and FIG. 6; but
the relative positions of the side button 52, the elastic member
58, the circuit board 60, and the connector 68 are shown. Apply
a pushing force on the side button 52 in a first direction 101 from
a first position shown in FIG. 5 to a second position shown in FIG.
6 before installing the battery 54, and the engaging hook 66 will
move along the first direction 101 as the side button 52 moves.
At this time, press the battery 54 toward the housing 51 when the
position of the recess 64 is aligning correspondingly to the engaging
hook 66. Then, release the force and the elastic member 58 will
push the side button 52 along with the engaging hook 66 from the
second position shown in FIG. 6 back to the first position shown
in FIG. 5. Consequently, the engaging hook 66 of the side button
52 can engage the recess 64 of the battery 54 to achieve the purpose
of fixing the battery 54. Of course, the engagement of the fixing
hooks 78 on the battery 54 with the engaging sinks 74 on the lower
case 56 can enhance the fixing effect of the battery 54. In addition,
because the side button 52 disengages from the connector 68 and
thus loses electrical connection with the connector 68, the side
button 52 at the second position shown in FIG. 6 is under the invalid
status. Once the side button 52 returns to the first position after
the battery 54 is fixed, the side button 52 can connect electrically
with the connector 68. At this time, the signal produced by triggering
the side button 52 can be delivered through the connector 68 to
the control circuit of the circuit board 60 to adjust the output
volume of the mobile phone 50.
Please refer to FIG. 7. FIG. 7 is a perspective view of installing
the battery 54, the lower case 56, and the housing 51 according
to the present invention. As shown in FIG. 7, fixing hook 78 on
the battery 54 fits with the engaging sink 74 of the lower case
56, and the engaging hook 66 engages with the recess 64 of the battery
54 through the lower case 56. Hence, it prevents the battery 54
from being removed from the housing 51 and the lower case 56.
Please refer to FIG. 8. FIG. 8 is a diagram of removing the battery
54 from the housing 51 according to the present invention. Similarly
to the above-mentioned process, when intending to remove the battery
54, a force is applied on the side button 52, moving the side button
52 from the first position shown in FIG. 5 to the second position
shown in FIG. 6. At this moment, the engaging hook 66 will come
off from the recess 64, leading to the battery 54 to be disassembled
from the housing 51 in a third direction 103.
Please notice that the function of the side button 52 is not only
limited to adjusting the volume but also can be used for other relative
operations of the mobile phone 50.
Compared with the prior art, the side button of the present invention
not only controls the volume of the mobile phone but also fixes
the battery. Such design will decrease additional steps of casting
molds and outward performance on the fixing member in the prior
art, and it leads to reduced risk in manufacturing and to consistency
in the performance of the mobile phone.
Those skilled in the art will readily observe that numerous modifications
and alterations of the device and method may be made while retaining
the teachings of the invention. Accordingly, the above disclosure
should be construed as limited only by the metes and bounds of the
appended claims.
