Abstract

Disclosed in the present invention is a combined portable power supply, comprising an upper housing and a lower housing which are detachably connected, wherein the upper housing is integrated with a charger, an input port of the charger is electrically connected to a charging plug, an output port of the charger is electrically connected to a battery pack by means of a charging circuit, and the battery pack is detachably connected to the upper housing; an inverter is integrated in the lower housing, the battery is electrically connected to an input end of the inverter by means of a discharging circuit, and an output end of the inverter is connected to a load for working. During the combined use of the present application, the upper housing and the lower housing are electrically connected by means of an aviation plug, then an alternating current can be used and output; when the present invention is used in a split manner, the battery pack can be independently charged by the upper housing, and the use is convenient.

Description

A combined portable power supply

Technical field

The invention belongs to the technical field of portable power supplies, and specifically relates to a combined portable power supply.

Background technique

Existing portable power supplies include battery packs, chargers, and inverters. The chargers and inverters are integrated together and built into the equipment power supply. There is another portable power supply that uses an external charger to control For charging the battery pack, the defect of the first structure is that the product is large in size and inconvenient to transport; the defect of the second is that it requires an additional charger, which is troublesome to carry.

Summary of the invention

The purpose of the present invention is to provide a combined portable power supply, which solves the defects of the above-mentioned portable power supply in the prior art.

In order to achieve the above objectives, the present invention provides the following technical solutions:

A combined portable power supply, comprising a detachable upper shell and a lower shell, the upper shell integrates a charger and other auxiliary circuits, the input port of the charger is electrically connected to a charging plug, and the charger The output port is electrically connected to the battery pack through the charging circuit, and the battery pack is detachably connected to the upper housing;

An inverter is integrated in the lower casing, the battery pack is electrically connected to the input end of the inverter through a discharge circuit, and the output end of the inverter is connected to a load to be operated.

Among them, other auxiliary circuits are related technical solutions that can be easily obtained by those skilled in the art, and will not be repeated here. The inverter may also be other devices that convert direct current into alternating current;

Preferably, the upper shell and the lower shell are electrically connected by an aviation plug.

Preferably, the cross section of the upper casing is polygonal, and each side is provided with a battery pack corresponding to it.

Preferably, a flexible anti-collision structure is provided at the bottom of the lower shell.

The six-sided edges and corners of the bottom of the lower shell are covered with rubber to form the flexible anti-collision structure.

Wherein, the upper shell is provided with a ventilation window to form a charging natural heat dissipation structure, and the lower shell is provided with an air duct, and a fan is provided in the air duct to dissipate heat from the inverter. The above structure is a conventional design in the field and will not be repeated here .

Compared with the prior art, the beneficial effects of the present invention are:

When the present application is used in combination, the upper and lower shells can be electrically connected through the aviation plug to use the output AC power. When split, the upper shell can separately charge the battery pack, which is convenient to use.
