Shared portable power supply circuit and shared portable power supply device capable of realizing forward and reverse insertion

Abstract

The invention discloses a shared portable power supply circuit which comprises a main circuit and a control circuit. The control circuit is connected with the main circuit. The shared portable power supply circuit is characterized in that a first connection pin, a common end pin and a second connection pin are arranged on the control circuit. The control circuit further comprises a power supply module; a signal pin which includes a first signal pin and a second signal pin, wherein one end of the first signal pin and one end of the second signal pin are connected with the main circuit; and a control module. The other end of the first signal pin is connected with the first connection pin, and the other end of the second signal pin is connected with the second connection pin. The power supplymodule is connected with the first connection pin through the first control module. The power supply module is connected with the second connection pin through the second control module. The invention also discloses a shared portable power supply device capable of realizing forward and reverse insertion. The shared portable power supply circuit is ingenious in design, the use material of the shared portable power supply device is effectively reduced and the structure design is more reasonable and safer.

Description

technical field [0001] The invention relates to the field of shared charging treasures, in particular to a shared charging treasure circuit and a shared charging treasure device that can be reversibly inserted. Background technique [0002] As a common charging device in daily life, charging treasure is widely used because it is easy to carry out and can charge mobile phones and other equipment at any time; the charging treasure device that appears on the market at present is placed inside the cavity used to charge the charging treasure On the bottom, there are generally five contact plugs or seven contact plugs, the middle contact plug is a common contact plug (grounding plug), and the left and right sides are symmetrical, that is, the five contact plugs are generally set as power supply. Contact plugs, signal contact plugs, public end contact plugs, signal contact plugs, power contact plugs; seven contact plugs are generally set as power contact plugs, signal sending conta...

[0002] As a common charging device in daily life, charging treasure is widely used because it is easy to carry out and can charge mobile phones and other equipment at any time; the charging treasure device that appears on the market at present is placed inside the cavity used to charge the charging treasure On the bottom, there are generally five contact plugs or seven contact plugs, the middle contact plug is a common contact plug (grounding plug), and the left and right sides are symmetrical, that is, the five contact plugs are generally set as power supply. Contact plugs, signal contact plugs, public end contact plugs, signal contact plugs, power contact plugs; seven contact plugs are generally set as power contact plugs, signal sending contact plugs, and signal receiving contact plugs , public end contact plug, signal receiving contact plug, signal sending contact plug, and power contact plug; the purpose of this setting can realize that when the power bank is plugged in front and back, the corresponding sockets on the power bank (symmetrical connection) holes) can correspond to the contact plugs one by one so as to realize the charging of the power bank and the signal connection, but this setting method is a waste of materials and increases the production cost of the enterprise, and urgently needs to be improved

[0003] In addition, there are shared charging treasures on the market. Users can scan the shared charging treasure cabinet to pay for the shared charging treasure. It is located at the bottom of the shared power bank cabinet. Due to the high voltage of the power module, once water seeps into the power module through the cavity of the power bank, it will be extremely dangerous.
