Abstract
A hand-held power tool, in particular a demolition hammer, includes an outer housing in which an electric motor for actuating an insert tool and an electronic unit for controlling the electric motor are accommodated. The outer housing has an opening into which a first interface module with an electromechanical interface for accommodating an exchangeable, rechargeable battery pack or at least a second interface module with a mains cable can be inserted as desired, in particular by a manufacturer of the hand-held power tool, to supply power to the electric motor and the electronic unit. Furthermore, a system including the hand-held power tool and the at least two interface modules is disclosed.
Claims12
A hand-held power tool, comprising:
- an electric motor configured to actuate an insert tool;
- an electronic unit configured to control the electric motor;
- and
- an outer housing in which the electric motor and the electronic unit are accommodated,
- a first interface module with an electromechanical interface for accommodating an exchangeable rechargeable battery pack;
- and
- at least a second interface module with a mains cable, wherein;
- the outer housing defines an opening configured for insertion of one of said first interface module and said at least a second interface module to supply power to the electric motor and the electronic unit,
- the outer housing comprises two half-shells, and
- the opening is formed by two partial openings of the two half-shells such that the first interface module or the at least one second interface module is held in one of the two partial openings of a corresponding one of the two half-shells in a form-fitting manner by way of a tongue-and-groove connection when the two half-shells are not yet assembled.
A hand-held power tool, comprising:
- an electric motor configured to actuate an insert tool;
- an electronic unit configured to control the electric motor;
- and
- an outer housing in which the electric motor and the electronic unit are accommodated,
- a first interface module with an electromechanical interface for accommodating an exchangeable rechargeable battery pack;
- at least a second interface module with a mains cable, wherein the outer housing defines an opening configured for insertion of one of said first interface module and said at least a second interface module to supply power to the electric motor and the electronic unit;
- and
- a mechanical percussion mechanism having a linearly oscillating percussion piston, wherein;
- the electric motor and the mechanical percussion mechanism form a percussion mechanism assembly that is accommodated at least partially in the outer housing,
- the electric motor has a motor shaft along a motor axis which drives the linearly oscillating percussion piston along a percussion mechanism axis, and
- the motor axis and the percussion mechanism axis are arranged at an angle of 45° to 135° to one another, and span a plane which extends substantially at right angles to the opening.
