  • Publication number: 20260225217
    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.

  • Publication number: 20260216853
    Abstract: An electric hand tool, in particular an impact hammer, with a tool receiving unit (1) for a tool arranged along an impact axis (X), a drive unit for the tool subsequently accommodated in a machine housing (2) and a handle (3) arranged opposite the tool receiving unit (1) on the machine housing (2), wherein at least one accumulator unit (8a; 8b) detachably fastened to the machine housing (2) is provided for the electrical power supply, wherein at least one housing recess (7a; 7b) extending transversely to the impact axis (X) is provided in the region of the machine housing (2) for the exchangeable accommodation of the accumulator unit (8a; 8b), in which the accumulator unit (8a; 8b) is arranged in such a way that the overall center of gravity with respect to the impact axis (X) in the radial direction lies within the lateral dimension of the drive unit.
