Problems solved by technology
Therefore, electrical devices or equipment such as garden tools, electric tools, and home appliances all need to be equipped with separate power supplies. If you encounter electric tools that need to work in different voltage modes, you need to provide two or more sets of power supplies, which is not only time-consuming and laborious. , but also caused great inconvenience to users

The invention relates to the field of power supply systems of electric tools, in particular to a power supply system and an electric tool system. The power supply system comprises a shell, a battery pack and an adapter, the shell is internally provided with a first battery pack cavity and a second battery pack cavity which are used for installing the battery pack, the adapter comprises an input end, a first adaptation interface, a second adaptation interface, a first switching structure and a second switching structure, the input end is electrically connected with the battery pack, and the second switching structure is electrically connected with the battery pack. The first adaptation interface and the second adaptation interface are configured to be matched with the first tool interface and the second tool interface respectively, the first switching structure and the second switching structure are electrically connected with the input end respectively, and the first switching structure and the second switching structure can be switched between a first state and a second state; different voltages can be output by adjusting the states of the first switching structure and the second switching structure. The power supply system can output two different working voltages and can be applied to electric tools with different working voltages, and the cost is saved.
Description
technical field [0001] The invention relates to the field of electric tools, in particular to a power supply system and an electric tool system. Background technique [0002] Most of the existing power supply components adopt a fixed power supply mode, that is, the connection mode between the battery packs is fixed, and in this case, the power supply components can only provide one output voltage. Therefore, electrical devices or equipment such as garden tools, electric tools, and home appliances all need to be equipped with separate power supplies. If you encounter electric tools that need to work in different voltage modes, you need to provide two or more sets of power supplies, which is not only time-consuming and laborious. , but also caused great inconvenience to users. Contents of the invention [0003] In view of the above shortcomings of the prior art, the present invention provides a power supply system and an electric tool system, so that a group of power supply...
