1. Technical Field
The present disclosure relates to batteries, particularly, to a battery pack.
2. Description of Related Art
Presently, electronic devices such as portable computers, mobile phones are equipped with an external battery pack to power the electronic devices if a built-in battery of the electronic device has been exhausted. Referring to
Therefore, it is desirable to provide a battery pack to overcome the described limitations.
Many aspects of the present disclosure are better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure.
Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Embodiments of the present disclosure will now be described in detail, with reference to the accompanying drawings.
Referring to
In detail, the power port 102 of the battery port 1 includes a first connection pin P1, a second connection pin P2, and a first power pin S1. The voltage conversion circuit 101 includes a first input terminal 1011, a second input terminal 1012, and an output terminal 1013. The first connection pin P1 is connected to an end (not labeled) of the battery S, the second connection pin P2 is connected to the first input terminal 1011 of the voltage conversion circuit 101, and the second input terminal 1012 of the voltage conversion circuit 101 is connected to the other end (not labeled) of the battery S. The output terminal 1013 is connected to the power pin S1.
When the battery pack 1 is not connected to the electronic device 2, the connection between the first connection pin P1 and the second connection pin P2 is cut off. Then the connection between the battery S and the voltage conversion circuit 10 is cut off accordingly.
The power port 201 of the electronic device 2 includes a third connection pin P3, a fourth connection pin P4, and a second power pin S2. The third connection pin P3 is electrically connected to the fourth connection pin P4. When the battery pack 1 is connected to the electronic device 2, the first connection pin P1, the second connection pin P2, and the first power pin S1 of the power port 102 are respectively connected to the third power pin P3, the fourth power pin P4, and the second power pin S2 of the power port 201. Because the third power pin P3 is electrically connected to the fourth power pin P4, the first connection pin P1 is electrically connected to the second connection pin P2 via the third power pin P3 and the fourth power pin P4. Then the first input terminal 1011 and the second input terminal 1012 of the voltage conversion circuit 20 are respectively connected to the two ends of the battery S. The voltage conversion circuit 20 converts the voltage of the battery S to the predetermined voltage and outputs the predetermined voltage to the electronic device 2 via the first power pin S1 and the second power pin S2. Obviously, the first power pin S1 and the second power pin S2 both includes an anode power pin (not shown) and a cathode power pin (not shown), when the first power pin S1 is connected to the second power pin S2, the voltage conversion circuit 20 and the electronic device 2 form a loop and then the voltage conversion circuit 20 powers the electronic device 2 via the first power pin S1 and the second power pin S2.
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, the examples hereinbefore described merely being exemplary embodiments of the present disclosure.
