Mobile Phone Patent Abstract
A mobile phone may be recharged from a set of batteries contained
in a battery box. A power transforming box mechanically and electrically
connected to the battery box is used to transform a voltage of the
batteries in the battery box into the applicable voltage of a mobile
phone. The power transforming box is equipped with a voltage switch
for selecting the applicable charging voltage from the charger.
The power input of the mobile phone is connected to the output of
the charger through a connecting wire. The charging device is suitable
for mobile phones of various types and can be used conveniently.
Furthermore, the charger has a function of displaying an incoming
phone number and may be equipped with a vibrator, flashers or sound
transducers to alert the user of the incoming call.
Mobile Phone Patent Claims
What is claimed is:
1. A charging device of a mobile phone suitable for mobile phones
of various types comprising: a battery box for retaining a plurality
of batteries; a power transforming box mechanically and electrically
connected to said battery box for transforming a voltage of said
plurality of batteries in said battery box into a voltage of the
mobile phone; and a voltage switch installed on said power transforming
box for selecting an output charging voltage from the charging device.
2. A charging device of a mobile phone suitable for mobile phones
of various types comprising: a battery box for placing batteries;
a power transforming box mechanically and electrically connected
to said battery box for transforming a voltage of said batteries
in said battery box into a voltage of a mobile phone, said power
transforming box being installed with a voltage switch, wherein
by said voltage switch, a charging voltage outputted from a charger
can be changed; and an antenna coupled to a circuit for displaying
an incoming phone number, for generating vibrations and for emitting
light or sound.
3. The charging device of a mobile phone suitable for mobile phones
of various types as recited in claim 1, wherein each of said plurality
of batteries in said battery box is a AA or AAA size battery.
4. The charging device of a mobile phone suitable for mobile phones
of various types as recited in claim 1, wherein the mobile phone
is directly inserted to said power transforming box.
5. The charging device of a mobile phone suitable for mobile phones
of various types as recited in claim 1, wherein a power input of
the mobile phone is connected to an output of the charging device
through a connecting cable.
6. The charging device of a mobile phone suitable for mobile phones
of various types as recited in claim 5, wherein one end of said
connecting cable is connected to an adapter of the mobile phone.
7. The charging device of a mobile phone suitable for mobile phones
of various types as recited in claim 5, wherein one end of said
connecting cable is installed with a DC connector coupled to the
charging device.
Mobile Phone Patent Description
FIELD OF THE INVENTION
The present invention relates to a portable charging device of
a mobile phone suitable for mobile phones of various types for charging
when no other charging source is available.
BACKGROUND OF THE INVENTION
Currently, the prior art chargers charge a mobile phone through
a car power source, a home power source and an office power source
as shown in FIGS. 6, 7, and 8. The chargers supply power through
an AC power source or a car cigar-lighter (12V 24V). The utilization
is restrictive. Namely, when away from the power supplies from the
car power source, home power source or office power source, the
mobile phone user may not recharge his battery.
To cause a mobile phone to be available even when the power of
a battery is exhausted, in general, standby batteries are carried
by users. However, it is possible |
