Abstract

A hand tool operating unit includes at least one operating member, and an electronic operating unit that has a position sensor configured to ascertain a position of the operating member. The hand tool operating unit additionally includes at least one further sensor that is configured to ascertain at least one characteristic variable.

Claims

1. A hand tool operating unit comprising:

at least one operating member;

an electronic operating unit that includes a position sensor configured to ascertain a position of the operating member; and

at least one further sensor configured to ascertain at least one characteristic variable.

2. The hand tool operating until according to claim 1, wherein the electronic operating unit includes the at least one further sensor.

3. The hand tool operating until according to claim 1, wherein the at least one further sensor is configured to ascertain at least one characteristic variable of a movement of an uncontrolled blocking incident.

4. The hand tool operating until according to claim 1, wherein the at least one further sensor includes an acceleration sensor.

5. The hand tool operating until according to claim 1, further comprising an evaluating device configured to as least one of influence and generate a motor control signal based at least in part upon a signal from the at least one further sensor.

6. The hand tool operating until according to claim 5, wherein the evaluating device is configured to interrupt an output of a driving power based at least in part upon a signal from the at least one further sensor.

7. The hand tool operating until according to claim 5, wherein the evaluating device includes a microcontroller.

8. The hand tool operating until according to claim 5, wherein at least the evaluating device is formed with analogue technology.

9. The hand tool operating until according to claim 1, further comprising a power control element configured to control a driving power.

10. The hand tool operating until according to claim 9, further comprising at least one motor connector configured to output the driving power.

11. The hand tool operating until according to claim 1, further comprising an operating unit housing element that connects the operating member and the electronic operating unit to form an assembly.

12. The hand tool operating until according to claim 11, wherein the operating unit housing element is configured to be installed in a hand tool housing that is at least substantially defined by at least one of a pistol-shaped and D-shaped grip.

13. A hand-held drilling machine, comprising:

a hand tool operating unit that includes;

at least one operating member;

an electronic operating unit that has a position sensor configured to ascertain a position of the operating member; and

at least one further sensor configured to ascertain at least one characteristic variable.
