Problems solved by technology

[0004] At present, under different working conditions, tools driven by the same AC and DC power supply need to be matched with battery packs of different voltages, and battery packs of each voltage need to be powered by corresponding power adapters for tools driven by AC and DC power sources. Therefore, consumers are using For tools driven by AC and DC power sources, it is necessary to purchase a variety of battery packs with different voltages and corresponding power adapters, which leads to high follow-up maintenance costs and use costs for tools driven by AC and DC power sources.

Embodiment Construction

[0055] Taking a pruning tool as an example, the pruning tool is usually used in two working conditions, one of which requires an operating voltage of 18V, and the other requires an operating voltage of 36V.

[0056] At present, when using the above-mentioned pruning tools, consumers usually purchase 18V and 36V battery packs and power adapters compatible with the battery packs to meet the use of the above-mentioned pruning tools under different working conditions, resulting in the above-mentioned pruning tools. The follow-up maintenance cost and use cost are very high.

[0057] In view of the above problems, an embodiment of the present invention provides a power adapter, the power adapter includes a DC power adapter, by setting an interface connection module group in the DC power adapter, and making the interface connection modules in the interface connection module group One-to-one correspondence and coupling with the battery pack interface, the interface connection modules ...

Abstract

The invention relates to a power adapter and an AC / DC power supply driving tool. The power adapter comprises a DC power adapter suitable for being coupled to a DC power supply. The DC power adapter comprises a battery pack interface unit and an interface connection module group, wherein the battery pack interface unit comprises a plurality of battery pack interfaces, and the battery pack interfaces are suitable for accessing battery packs with corresponding voltage; and the interface connection module group comprises an input end, an output end and more than two interface connection modules coupled between the input end and the output end, the interface connection modules respectively correspond and are coupled to the battery pack interfaces, and the interface connection modules are coupled according to a preset connection mode. The application of the scheme can reduce the use cost and follow-up maintenance cost of the AC / DC power supply driving tool.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a power adapter and a tool driven by an AC or DC power supply. Background technique [0002] Tools driven by alternating current and direct current power, that is, electric tools that can use alternating current (AC) power or direct current (DC) power as the working power supply, including but not limited to air compressors, pressure washers, lawn mowers, chain saws, Cleaning tools, pruning tools, handheld power tools, snow blowers, backpack power tools and more. [0003] Typically, dual purpose power tools operate on AC power when AC power is available. Combination power tools operate on DC power when AC power is not available. By inserting a battery pack into the tool driven by AC and DC power, the tool driven by AC and DC power can obtain DC power for working. [0004] At present, under different working conditions, tools driven by the same AC and DC power supply nee...
