The plug body of the present invention has a small overall size, is easy to carry, has low manufacturing cost, and has the function of a mobile power source, and is used as a temporary charging power source for emergency standby. The mobile power adapter plug is equipped with a rechargeable battery unit in the existing structure. Therefore, under the existing plug body volume, the size or number of the rechargeable battery unit can be increased as much as possible to increase the charging capacity of the rechargeable battery unit.

The detailed description and technical content of the present invention are described below with reference to the drawings, but the drawings are only for reference and explanation, and are not intended to limit the creation.

As shown in FIGS. 1 and 2, the present invention provides a mobile power adapter plug 1 including a plug body 11. The plug body 11 as shown in the figure has a small overall size, is easy to carry, and has low manufacturing cost. The plug body 11 includes a variable voltage charging management module 12, a rechargeable battery unit 15 electrically connected to the variable voltage charging management module 12, and a separate battery. A pair of plugs 13 and at least one USB socket 14 of the variable voltage charging management module 12 are connected. The transformer charging management module 12 receives an AC voltage from the pair of plugs 13, converts the voltage into a DC voltage for storage in the rechargeable battery unit 15, or boosts the voltage into a suitable DC voltage to output power from the USB outlet 14.

The transformer charging management module 12 shown in FIG. 1 includes a control chip 121 and a circuit board 122 electrically coupled to the control chip 121. Generally, the control wafer 121 and/or the circuit board 122 are equipped with at least a buck-boost conversion circuit and a charge and discharge management circuit. The buck-boost conversion circuit includes a DC voltage that is stepped down and converted into an AC voltage of 110 to 220 V, stored in the rechargeable battery unit 15, and converted into a 5V or other corresponding USB peripheral device by using a charge and discharge management circuit. / Suitable power supply.

Specifically, when the mobile power transfer socket 1 of the present embodiment is plugged into the commercial power through the pair of plugs 13, the power supply/charging can be directly provided through the device (not shown) plugged into the USB socket 14. When the device connected to the USB socket 14 is not fully charged, the mobile power adapter plug 1 of the present embodiment is removed (ie, separated from the mains slot), and the device can still be continuously charged. Therefore, the mobile power adapter plug 1 can be used as a stand-alone mobile power source, and can also be used as a dual-function plug for charging directly into a commercial power socket.

In addition, the plug body 11 further includes a slot 16 , and the pair of plugs 13 are rotatably received in the slot 16 , so that the mobile power adapter plug 1 of the embodiment is more convenient to carry and carry, and the pair of plugs 13 are also less susceptible to Damaged by collision. The pair of plugs 13 as shown in the figure are preferably one-piece conductor portions 131 so as to be correspondingly inserted into the slots of the mains (not shown).

The rechargeable battery unit 15 of the present embodiment is selected from the group consisting of a nickel-cadmium battery (Ni-Cd), a nickel-hydrogen battery (Ni-MH), a lithium ion battery (Li-ion), a lithium ion polymer battery (Li-Poly), Lithium iron phosphate battery (Li-Fe), lithium titanate battery (Li-Ti) and alkaline battery (Alkaline). In addition, the number of the USB sockets 14 is preferably two or more, and the connection interface of the USB socket 14 can be a USB 2.0, a USB 3.0, a USB 3.1 or a USB Type-C interface as needed. Since the USB (Universal Serial Bus) connection interface has the characteristics of hot swapping/Hot plugging, it can directly directly remove the USB adapter plug 1 (power off). Inserting or removing each USB electronic peripheral product will not cause the USB electronic peripheral products to burn out.

In particular, the control chip 121 and/or the circuit board 122 of the present embodiment further has, for example, a connection interface for identifying the different USB peripheral devices and their use for performing the charging definition automatic identification function. By means of a buck-boost conversion circuit, a charge and discharge management circuit or other protection circuit, it is possible to control the detection and switching of the insertion and abnormal circuit protection of different devices, and perform overcharge/overdischarge/overcurrent/short circuit on the rechargeable battery unit 15. Important protection. The charge and discharge management circuit can also set corresponding voltage/current protection values for the different batteries to protect the functions of over-discharge/over-voltage/over-current of the rechargeable battery unit 15. Therefore, the mobile power transmission plug 1 of the present invention can automatically output corresponding current and voltage and ensure good power supply/charging quality.

Furthermore, the embodiment further includes a display lamp 17 electrically connected to the transformer charging management module 12. The display lamp 17 described herein is preferably an LED display lamp 17 controlled by the control chip 121, and the LED display lamp 17 is disposed adjacent to the USB socket 14 for illuminating the connection to charge, energize, and charge the battery unit 15 or Other status.

It should be noted that the mobile power adapter plug 1 of the present embodiment is basically equipped with the rechargeable battery unit 15 in the conventional structure, so that the plug body 11 is small in size, easy to carry, and low in cost. The charging capacity of the rechargeable battery unit 15 is limited by the overall volume of the plug body 11, so that the size or number of the rechargeable battery cells 15 is maximized under the volume of the existing plug body 11.
