Die Handwerkzeugmaschine, insbesondere der Akkuschrauber, umfasst die Energieversorgungseinheit zur Energieversorgung der Antriebseinheit, insbesondere des Antriebsmotors. Bevorzugt handelt es sich bei der Handwerkzeugmaschine um eine akkubetriebene Handwerkzeugmaschine, welche mittels zumindest eines Akkus, insbesondere mittels eines Handwerkzeugmaschinenakkupacks, betreibbar ist. Hierdurch findet dann die Bereitstellung der Energie durch die Energieversorgungseinheit mittels des zumindest einen Akkus statt. Im Rahmen der vorliegenden Erfindung soll unter einem "Handwerkzeugmaschinenakkupack" ein Zusammenschluss von zumindest einer Akkuzelle und einem Akkupackgehäuse verstanden werden. Der Handwerkzeugmaschinenakkupack ist vorteilhafter Weise zur Energieversorgung von handelsüblichen akkubetriebenen Handwerkzeugmaschinen ausgebildet. Die zumindest eine Akkuzelle kann beispielsweise als eine Li-lon-Akkuzelle mit einer Nennspannung von 3,6 V ausgebildet sein. In dieser Ausführungsform der Erfindung ist der zumindest eine Akku gehäusefest im Wesentlichen innerhalb des Handwerkzeugmaschinengehäuses angeordnet, insbesondere angebracht, ganz insbesondere montiert. In einer alternativen Ausführungsform ist es jedoch auch möglich, dass der zumindest eine Akku als ein wechselbarer Akku, insbesondere als ein wechselbarer Handwerkzeugmaschinenakkupack, ausgebildet ist. Alternativ kann es sich bei der Handwerkzeugmaschine um eine netzbetriebene Handwerkzeugmaschine handeln, welche mittels einem Stromversorgungskabel an eine externe Netzsteckdose verbindbar ist. Dabei kann die externe Netzsteckdose eine Spannung von beispielsweise 100 V, 110 V, 120 V, 127 V, 220 V, 230 V oder 240 V mit 50 Hz oder 60 Hz bereitstellen, aber auch eine Dreiphasenwechselspannung. Die möglichen Ausgestaltungen der externen Netzsteckdose und die damit verbundenen verfügbaren Spannungen sind dem Fachmann hinlänglich bekannt. Somit ist die vorliegende Erfindung nicht auf die Art der Energieversorgungseinheit beschränkt.The hand-held power tool, in particular the cordless screwdriver, includes the energy supply unit for supplying energy to the drive unit, in particular the drive motor. The hand-held power tool is preferably a battery-operated hand-held power tool, which can be operated by means of at least one battery, in particular by means of a hand-held power tool battery pack. As a result, the energy is then provided by the energy supply unit using the at least one battery. In the context of the present invention, a “handheld power tool battery pack” is to be understood as a combination of at least one battery cell and a battery pack housing. The handheld power tool battery pack is advantageously designed to supply energy to commercially available battery-operated handheld power tools. The at least one battery cell can be designed, for example, as a Li-ion battery cell with a nominal voltage of 3.6 V. In this Embodiment of the invention, the at least one battery is arranged, in particular attached, most particularly mounted, in a fixed manner essentially within the hand-held power tool housing. In an alternative embodiment, however, it is also possible for the at least one battery to be designed as a replaceable battery, in particular as a replaceable hand-held power tool battery pack. Alternatively, the hand-held power tool can be a mains-operated hand-held power tool, which can be connected to an external power socket using a power supply cable.

The possible configurations of the external power socket and the associated available voltages are well known to those skilled in the art.

The direction of rotation selection element is also intended to forward a signal to the control unit for selecting the clockwise direction of rotation, the counterclockwise direction of rotation and the neutral position of the direction of rotation.
Die Steuereinheit der Handwerkzeugmaschine ist dazu vorgesehen, die Antriebseinheit, insbesondere den Antriebsmotor, zu steuern und/oder zu regeln. Hierzu empfängt die Steuereinheit Signale von der Signalgebereinheit. Die Betätigungseinheit ist dazu ausgebildet, von einem Benutzer betätigt zu werden und eine mechanische Betätigung an die Signalgebereinheit weiterzuleiten. Die Signalgebereinheit wandelt die mechanische Betätigung in ein Signal, insbesondere ein elektrisches Signal, um. Anschließend übermittelt die Signalgebereinheit das Signal an die Steuereinheit. Die Steuereinheit empfängt dieses Signal, verarbeitet es und steuert und/oder regelt die Antriebseinheit auf Basis des Signals der Signalgebereinheit.The control unit of the hand-held power tool is intended to control and/or regulate the drive unit, in particular the drive motor. For this purpose, the control unit receives signals from the signal generator unit. The actuation unit is designed to be actuated by a user and to forward a mechanical actuation to the signal transmitter unit. The signal generator unit converts the mechanical actuation into a signal, in particular an electrical signal. The signal generator unit then transmits the signal to the control unit. The control unit receives this signal, processes it and controls and/or regulates the drive unit based on the signal from the signal generator unit.

Der Benutzer kann das Betätigungselement mittels zumindest eines Fingers in die erste Richtung betätigen, um die Handwerkzeugmaschine zu steuern und/oder zu regeln. Die erste Richtung ist hierbei relativ zur Werkzeugachse und ist erfindungsgemäß parallel zur Werkzeugachse.The actuating element of the actuating unit is mounted movably relative to the hand-held power tool housing and can be actuated by the user in the first direction. The user can operate the actuating element in the first direction using at least one finger in order to control and/or regulate the hand-held power tool. The first direction is relative to the tool axis and, according to the invention, is parallel to the tool axis.

Das Signalgeberelement der Signalgebereinheit ist relativ zu dem Handwerkzeugmaschinengehäuse bewegbar gelagert und wird über die Betätigungseinheit in die zweite Richtung betätigt. Die zweite Richtung ist hierbei relativ zur Werkzeugachse und kann in einer Ausführungsform quer zur Werkzeugachse sein. Es ist auch denkbar, dass die zweite Richtung im Wesentlichen senkrecht zur Werkzeugachse ist.The signal generator element of the signal generator unit is mounted movably relative to the hand-held power tool housing and is actuated in the second direction via the actuation unit. The second direction is relative to the tool axis and in one embodiment can be transverse to the tool axis. It is also conceivable that the second direction is essentially perpendicular to the tool axis.
In einer Ausführungsform ist die zweite Richtung winklig zur ersten Richtung ausgebildet. Weiter ist die erste Richtung in einem Winkel im Bereich von 1° bis 15°, insbesondere im Bereich von 2° bis 10°, ganz insbesondere im Bereich von 3° bis 8°, zur zweiten Richtung angeordnet. Aufgrund der winkligen Anordnung der zweiten Richtung zur ersten Richtung kann die Handwerkzeugmaschine, insbesondere das Handwerkzeugmaschinengehäuse, kompakter ausgebildet werden. Gleichzeitig wird mittels der winklige Anordnung eine zuverlässige Betätigung der Signalgebereinheit durch die Betätigungseinheit ermöglicht.In one embodiment, the second direction is formed at an angle to the first direction. Furthermore, the first direction is arranged at an angle in the range of 1° to 15°, in particular in the range of 2° to 10°, most particularly in the range of 3° to 8°, to the second direction. Due to the angular arrangement of the second direction relative to the first direction, the hand-held power tool, in particular the hand-held power tool housing, can be designed to be more compact. At the same time, the angled arrangement enables reliable actuation of the signal generator unit by the actuation unit.
In einer Ausführungsform weist das Betätigungselement zumindest eine Betätigungsfläche auf, wobei die Betätigungsfläche in einem Winkel im Bereich von 60° bis 90°, insbesondere im Bereich von 65° bis 85°, ganz insbesondere im Bereich von 70° bis 80°, zur Werkzeugachse angeordnet ist.

Mittels dem Federelement wird ermöglicht, dass nach der Betätigung der Betätigungseinheit und der Signalgebereinheit die Betätigungseinheit, insbesondere das Betätigungselement, in eine Neutralstellung gebracht wird. In der Neutralstellung kann das Betätigungselement erneut durch den Benutzer betätigt werden. Es ist auch denkbar, dass die Betätigungseinheit zumindest ein Federelement zur Rückführung des Betätigungselements in die Neutralstellung aufweist. Bei einer Ausgestaltung, bei der das Signalgeberelement an dem Aufnahmeelement anliegt oder sich abstützt, ist es möglich, dass die Aufnahmefläche zumindest teilweise poliert ist, um eine Reibung zwischen dem Signalgeberelement und dem Aufnahmeelement über die Aufnahmefläche zumindest zu reduzieren, insbesondere zu minimieren. Das Aufnahmeelement kann im Wesentlichen parallel zum Betätigungselement angeordnet sein, wobei die Anordnung von dem Aufnahmeelement im Wesentlichen gegenüberliegend zu dem Betätigungselement in axialer Richtung zur Werkzeugachse sein kann. Erfindungsgemäß ist das Betätigungselement und das Aufnahmeelement einstückig ausgebildet.According to the invention, the actuation unit has at least one receiving element for receiving the signal transmitter element, the receiving element comprising a receiving surface and the receiving surface at an angle in the range of 70° to 110°, in particular in the range of 80° to 105°, most particularly in the range of 90° ° to 100°, is arranged to the tool axis. The receiving element is designed to establish an operative connection between the actuation unit and the signal generator unit, in particular the signal generator element. The recording of the signal transmitter element by the receiving element can be positive, non-positive and/or material. In addition, it is conceivable that the signal generator unit has at least one spring element for acting on the signal generator element. The signal transmitter element can rest on the receiving element via the receiving surface or can be supported on the receiving surface. The spring element makes it possible for the actuation unit, in particular the actuation element, to be brought into a neutral position after the actuation of the actuation unit and the signal generator unit. In the neutral position, the actuating element can be actuated again by the user. It is also conceivable that the actuation unit has at least one spring element for returning the actuation element to the neutral position. In an embodiment in which the signal transmitter element rests or is supported on the receiving element, it is possible for the receiving surface to be at least partially polished in order to at least reduce, in particular minimize, friction between the signal transmitter element and the receiving element via the receiving surface. The receiving element can be arranged essentially parallel to the actuating element, wherein the arrangement of the receiving element can be essentially opposite to the actuating element in the axial direction to the tool axis. According to the invention, the actuating element and the receiving element are designed in one piece.

Der erste Führungssteg und die Führungsnut ermöglichen eine sichere und zuverlässige Führung der Betätigungseinheit während der Betätigung der Betätigungseinheit.In one embodiment, the actuation unit has at least a first guide web and the hand-held power tool housing comprises at least one guide groove, wherein the guide groove supports the first guide web for, in particular axial, guidance of the actuation unit. The first guide web is formed essentially transversely to the tool axis on the actuation unit. The first guide web is preferably formed in one piece with the actuation unit, it being also conceivable that the first guide web forms a positive, non-positive and/or material connection with the actuation unit. It is also possible for two first guide bars to be provided. The guide groove is formed essentially parallel to the tool axis on the hand-held power tool housing, in particular on one of the housing elements. Furthermore, the guide groove is shaped in such a way that it receives and movably supports the first guide web, in particular in a form-fitting manner. The movable mounting of the first guide web through the guide groove enables the actuation unit to be guided, in particular axially. The guide groove is formed on the hand-held power tool housing, in particular on one of the housing elements, by at least two guide groove elements. Here, the guide groove elements can be formed in one piece with the hand-held power tool housing. It is conceivable that four guide groove elements are designed for, in particular axial, guidance of the first guide web. Furthermore, it is conceivable that the guide groove elements are formed on one of the housing elements. The first guide web and the guide groove enable safe and reliable guidance of the actuation unit during operation of the actuation unit.
In einer Ausführungsform weist die Betätigungseinheit zumindest einen zweiten Führungssteg auf und das Handwerkzeugmaschinengehäuse umfasst zumindest eine Führungsschiene, wobei der zweite Führungssteg an der Führungsschiene zur, insbesondere axialen, Führung der Betätigungseinheit anliegt. Der zweite Führungssteg ist im Wesentlichen quer zur Werkzeugachse an der Betätigungseinheit ausgebildet. Bevorzugt ist der zweite Führungssteg einstückig mit der Betätigungseinheit ausgebildet. Es ist auch möglich, dass der zweite Führungssteg mit der Betätigungseinheit eine form-, kraft- und/oder stoffschlüssige Verbindung ausformt. Weiter ist es denkbar, dass zwei zweite Führungsstege ausgebildet sind. Die Führungsschiene ist im Wesentlichen parallel zur Werkzeugachse an dem Handwerkzeugmaschinengehäuse, insbesondere an einem der Gehäuseelemente, ausgeformt. Zudem ist die Führungsschiene derart ausgeformt, dass der zweite Führungssteg an der Führungsschiene anliegt und bewegbar gelagert ist. Die bewegbare Lagerung des zweiten Führungsstegs durch die Führungsschiene ermöglicht die, insbesondere axiale, Führung der Betätigungseinheit. Zusätzlich ermöglicht die Führungsschiene eine sichere und zuverlässige axiale Bewegung der Betätigungseinheit und verhindert eine rotatorische Bewegung der Betätigungseinheit, insbesondere des Betätigungselements. Die Führungsschiene ist an dem Handwerkzeugmaschinengehäuse, insbesondere an einem der Gehäuseelemente, ausgeformt und in einer Ausführungsform einstückig mit dem Handwerkzeugmaschinengehäuse, insbesondere einem der Gehäuseelemente, ausgebildet. Es ist denkbar, dass die Führungsschiene an jeweils einem der Gehäuseelemente ausgebildet ist. Der zweite Führungssteg und die Führungsschiene ermöglichen eine sichere und zuverlässige, insbesondere axiale, Führung der Betätigungseinheit während der Betätigung der Betätigungseinheit.In one embodiment, the actuation unit has at least one second guide web and the hand-held power tool housing comprises at least one guide rail, the second guide web resting on the guide rail for, in particular axial, guidance of the actuation unit.

In addition, the guide rail is shaped in such a way that the second guide web rests on the guide rail and is movably mounted. The movable mounting of the second guide web by the guide rail enables the actuation unit to be guided, in particular axially. In addition, the guide rail enables safe and reliable axial movement of the actuation unit and prevents rotational movement of the actuation unit, in particular of the actuation element. The guide rail is formed on the hand-held power tool housing, in particular on one of the housing elements, and in one embodiment is formed in one piece with the hand-held power tool housing, in particular one of the housing elements. It is conceivable that the guide rail is formed on one of the housing elements. The second guide web and the guide rail enable safe and reliable, in particular axial, guidance of the actuation unit during actuation of the actuation unit.
Hierbei weist der erste Führungssteg einen geringeren radialen Abstand zur Werkzeugachse auf, als der zweite Führungssteg. Durch verschiedene radiale Abstände des ersten und zweiten Führungsstegs zur Werkzeugachse wird eine sichere und zuverlässige axiale Führung der Betätigungseinheit sichergestellt.The first guide web has a smaller radial distance from the tool axis than the second guide web. Different radial distances between the first and second guide webs from the tool axis ensure safe and reliable axial guidance of the actuation unit.
