Hand-held impact power tool with pressing force-adapted power regulation

Abstract

A hand-held impact power tool having an electric motor drive unit for generating a rotary drive movement, which converts a subsequent impact mechanism unit into an alternating linear impact movement, which impacts a percussion drill or chisel hammer releasably locked in a subsequent tool receiving unit. A housing assembly composed of an outer housing with a handle and a base housing resiliently mounted in the impact force direction accommodates the impact mechanism unit, wherein an electronic control unit is also provided for the pressing force-adapted power regulation of the electric motor drive unit based on a current pressing force determined by means of a sensor on the percussion drill or chisel hammer when machining a workpiece, wherein the sensor is arranged on an electronic circuit board that at least partially forms the electronic control unit and is accommodated within the outer housing in such a way that the sensor is positioned adjacent to a detection element arranged on the base housing side.
