Mobile Phone Patent Description
BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone battery, and more
particularly to a mobile phone battery that enables an emergency
charging of the mobile phone simply with a general dry cell without
the need of an additional battery charger.
Mobile communication has been playing an important role in the
rapidly developed technological fields. Consumers place more reliance
on mobile phones than ever. The mobile phone is characterized in
the convenience it provides in electronic communication, and it
enables a user to keep contact with others at any place and at any
time. The mobile phone obtains its operating power from a battery
that might run out of power and requires recharging through a charger.
However, an outlet for an adapter of the charger to plug is not
always available at any place, and a user would usually not carry
an additional battery or batteries along with the mobile phone.
When the mobile phone is battery low, particularly when it is used
outdoors, the user could not help but watching the mobile phone
to shut down automatically.
To solve the above problem, there is developed an emergency charger
for a mobile phone user to charge a mobile phone battery with a
general dry cell. Please refer to FIG. 1 that shows a conventional
emergency charger 1 for charging a mobile phone 2, and to FIG. 2
that shows the use of the emergency charger 1 to charge the mobile
phone 2 with a rectangular dry cell 3. As shown, the emergency charger
1 includes a connector 11 adapted to plug into a socket at a lower
end of the mobile phone 2, and a charging base 12 connected to the
connector 11. The charging base 12 is provided at one side surface
with outward projected positive and negative contacts 121 in the
form of two circles. One of the two contacts 121 is formed from
a plurality of elastic curved segments, so that the two contacts
121 separately correspond to positive and negative contacts of the
rectangular dry cell 3. When the dry cell 3 is attached to the positive
and the negative contacts 121 on the charging base 12 of the emergency
charger 1, the dry cell 3 is securely connected to the charging
base 12. The charging base 12 is internally provided with a step-down
means to change a direct current of 9V supplied by the dry cell
3 into a direct current having a voltage suitable for storing in
the mobile phone battery. Direct current passing through the step-down
means charges the mobile phone battery via the connector 11. In
this manner, a mobile phone battery may be recharged with the emergency
charger 1 and the rectangular dry cell 3 in the event there are
not back-up battery and charger available for charging the mobile
phone.
However, the conventional emergency charger 1 has dimensions almost
equal to that of a normal mobile phone battery. It seemed to be
more convenient to carry an additional mobile phone battery than
an emergency charger 1 because a user carrying the mobile phone
battery needs not to find a store for buying the dry cell 3. In
brief, the conventional emergency charger 1 does not solve the problem
of charging a mobile phone battery conveniently.
It is therefore desirable to develop a mobile phone battery that
could be recharged with a general dry cell in an emergency without
the need of other charger.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a mobile
phone battery that could be recharged simply with a general dry
cell in an emergency without the need of other charger.
To achieve the above and other objects, the mobile phone battery
of the present invention mainly includes a cover being provided
at a predetermined position with an opening, positive and negative
contacts located behind the cover and accessible via the opening
of the cover for electrically connecting to a rectangular dry cell,
and step-down means provided at an inner side of the cover and having
a power output electrically connected to a power input of the mobile
phone battery. With the above arrangements, an emergency charging
of the mobile phone battery is possible simply by attaching a rectangular
dry cell to the positive and the negative contacts of the mobile
phone battery without using other battery charger.
BRIEF DESCRIPTION OF THE DRAWINGS
The structure and the technical means adopted by the present invention
to achieve the above and other objects can be best understood by
referring to the following detailed description of the preferred
embodiments and the accompanying drawings, wherein
FIG. 1 shows a conventional emergency charger for charging a mobile
phone;
FIG. 2 shows the use of the emergency charger of FIG. 1 to charge
the mobile phone with a dry cell;
FIG. 3 is an exploded perspective view of a mobile phone battery
according to the present invention;
FIG. 4 shows the battery of FIG. 3 in an assembled state before
connecting to a mobile phone and a rectangular dry cell; and
FIG. 5 shows the battery of FIG. 3 is connected to a mobile phone
and charged through a rectangular dry cell.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to FIG. 3 that is an exploded perspective view of
a mobile phone battery arrangement 4 according to the present invention.
As shown, the mobile phone battery arrangement 4, which will be
referred to as the battery 4 hereinafter for the purpose of simplicity,
includes a cover 41 having an opening 42 formed at a predetermined
position, round positive and negative contacts 421 located immediately
behind the cover 41 and accessible via the opening 42, and step-down
means 43 provided at an inner side of the cover 41. One of the two
round contacts 421 is formed from a plurality of elastic curved
segments and is electrically connected to the step-down means 43.
The step-down means 43 has a power output electrically connected
to a power input of a battery cell disposed behind the cover.
Please refer to FIG. 4 that shows the battery 4 in an assembled
state. As shown, the assembled battery 4 may be connected to a mobile
phone 2 in a manner as specified by a mobile phone manufacturer,
and a rectangular dry cell 3 may be connected to the battery 4 by
plugging positive and negative contacts of the rectangular dry cell
3 onto positive and negative contacts 421, respectively, of the
battery 4 via the opening 42. FIG. 5 shows the battery 4 has been
attached to the mobile phone 2 with the rectangular dry cell 3 plugged
onto the battery 4 via the opening 42. When the positive and the
negative contacts of the rectangular dry cell 3 are firmly connected
to the positive and the negative contacts 421 of the battery 4,
the rectangular dry cell 3 is securely attached to the battery 4
at the opening 42 to charge the battery 4 immediately. In other
words, the battery 4 may be directly charged with a general dry
cell 3 to enable an emergency charging of the mobile phone 2 without
using devices other than components originally supplied along with
the mobile phone 2. To enable firm connection of the rectangular
dry cell 3 to the battery 4 via the opening 42, the opening 42 is
preferably a rectangular opening.
With the above-described arrangements, a user needs only to buy
a rectangular dry cell 3 at a nearby store to charge the battery
4 when the latter is out of power. The user does not need to carry
a battery charger along with the mobile phone 2 and the latter is
therefore more convenient for use.
