Problems solved by technology

[0002] During the use of existing electric tools, a tool host can usually only use a battery pack with a specific output voltage. For example, when the rated voltage of the tool host is 18V at rated power, the tool host can only use A battery pack with an output voltage of 18V, while a battery pack with an output voltage of 56V, 36V cannot usually be used
In this way, when a tool host with a rated voltage of 18V needs a battery pack to supply power, and is limited by working conditions, there is only a battery pack with an output voltage of 36V. At this time, the battery pack cannot supply power to the tool host, affecting work continuation

Embodiment Construction

[0029] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0030] The invention provides an electric tool. figure 1 Shown is a schematic structural view of the electric tool of the present invention. Please refer to figure 1 , the electric tool 10 of the present invention includes a main tool 100 and a battery pack 200 .

[0031] In the present invention, the tool host 100 includes an electrical device ( figure 1 unmarked), the electric device can use the electric energy of the battery pack 200 to realize the tool function, that is to say, the electric device is the main part of the tool host 100, which can convert electric energy into mechanical energy, and realize the tool function in a mechanical form. In this embodiment, the electrical device also has a rated voltage under normal working conditions.

[0032] The battery pack 200 includes a cell unit ( figure 1 (not numbered in) or a plur...

Abstract

The invention discloses an electric tool. The electric tool comprises a tool host and a battery pack. The tool host comprises a power device. The power device possesses a rated voltage. The battery pack comprises an electrical core unit and an output terminal. The electrical core unit possesses an electrical core voltage and the output terminal possesses one output voltage. The battery pack provides power for the tool host through the output terminal. The tool host also comprises a main identification module capable of identifying the battery pack, a main adjusting module which adjusts electric energy output by the output terminal into electric energy adapted to the power device and a main control module controlling the main adjusting module. The battery pack also comprises a secondary identification module capable of identifying the power device, a secondary adjusting module which adjusts the electric energy output by the output terminal of the battery pack and makes the electric energy match with the power device and a secondary control module controlling the secondary adjusting module. The power device in the electric tool can use various kinds of battery packs possessing different output voltages to provide power for the power device.

Description

technical field [0001] The invention relates to a power tool, in particular to a power tool whose output voltage of a battery pack can be converted. Background technique [0002] During the use of existing electric tools, a tool host can usually only use a battery pack with a specific output voltage. For example, when the rated voltage of the tool host is 18V at rated power, the tool host can only use A battery pack with an output voltage of 18V, while a battery pack with an output voltage of 56V, 36V cannot usually be used. In this way, when a tool host with a rated voltage of 18V needs a battery pack to supply power, and is limited by working conditions, there is only one battery pack with an output voltage of 36V. At this time, the battery pack cannot supply power to the tool host, affecting Work continues. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide an electric tool in which...
