Furthermore, an output axis of an output unit of the handheld power tool preferably runs in the plane of the input and output axes. The output axis thus preferably extends in the plane of the input and output axes. In addition, the housing element is preferably provided to accommodate components and / or units of the handheld power tool and / or to surround them and / or to protect them from damage. “Provided” is to be understood in particular to be specially designed and / or specially equipped.

Die Energiespeichervorrichtung ist vorzugsweise in die Energiespeicheraufnahmeschnittstelle einschiebbar oder auf die Energiespeicheraufnahmeschnittstelle aufschiebbar ausgebildet. Somit erfolgt eine Verbindung der Energiespeichervorrichtung und der Energiespeicheraufnahmeschnittstelle insbesondere infolge einer translatorischen Bewegung der Energiespeichervorrichtung relativ zur Energiespeicheraufnahmeschnittstelle. Besonders bevorzugt wird die Energiespeichervorrichtung zu einer Anordnung an der Energiespeicheraufnahmeschnittstelle zumindest mittels des Aufnahmeführungselements entlang der Hauptführungsachse des Aufnahmeführungselements geführt. Somit ist das Aufnahmeführungselement vorzugsweise als Einschubführungselement oder als Aufschubführungselement ausgebildet. Das Aufnahmeführungselement ist bevorzugt schienenförmig oder rippenförmig ausgebildet. Es ist jedoch auch denkbar, dass das Aufnahmeführungselement eine andere, einem Fachmann als sinnvoll erscheinende Ausgestaltung aufweist, wie beispielsweise eine Ausgestaltung als Magnetkraftführungsschiene usw. Mittels der erfindungsgemäßen Ausgestaltung der Schleifmaschinengehäusevorrichtung kann vorteilhaft eine kompakte Anordnung der Energiespeicheraufnahmeschnittstelle am Gehäuseelement ermöglicht werden, insbesondere im Zusammenhang mit einer am Gehäuseelement angeordneten Partikelauffangbehälterschnittstelle der Schleifmaschinengehäusevorrichtung.

Thus, the energy storage receiving interface is preferably provided to receive an energy storage device designed as a storage battery device. The energy storage device can preferably be inserted into the energy storage receiving interface or onto the energy storage receiving interface designed to be pushed open. The energy storage device and the energy storage receiving interface are thus connected, in particular as a result of a translational movement of the energy storage device relative to the energy storage receiving interface. Particularly preferably, the energy storage device is guided to an arrangement at the energy storage receptacle interface at least by means of the receptacle guide element along the main guide axis of the receptacle guide element. Thus, the receiving guide element is preferably designed as an insertion guide element or as a slide-on guide element. The receiving guide element is preferably designed in the form of rails or ribs. However, it is also conceivable that the receiving guide element has a different configuration that appears sensible to a person skilled in the art, such as, for example, a configuration as a magnetic force guide rail, etc. The configuration of the grinding machine housing device according to the invention can advantageously enable a compact arrangement of the energy storage receiving interface on the housing element, in particular in connection with a particle collecting container interface of the grinding machine housing device arranged on the housing element.

Insbesondere schließen die Hochachse und die Aufnahmeführungsebene einen Winkel ein, der kleiner ist als 60°, bevorzugt kleiner ist als 40° und besonders bevorzugt kleiner ist als 32°. Der Winkel wird vorzugsweise auf einer dem Gehäuseelement zugewandten Seite der Aufnahmeführungsebene gemessen. Zudem wird der Winkel vorzugsweise in einem einer Werkzeugaufnahme zugewandten Bereich zwischen der Aufnahmeführungsebene und der Hochachse gemessen. Die Hochachse verläuft vorzugsweise in der An- und Abtriebsachsenebene. Insbesondere erstreckt sich die Hochachse zumindest im Wesentlichen parallel zu einer Haupterstreckungsrichtung des Gehäuseelements. Hierbei verläuft die Hochachse besonders bevorzugt zumindest in einem am Gehäuseelement angeordneten Zustand der Antriebseinheit zumindest im Wesentlichen parallel zur Antriebsachse der Antriebseinheit. Unter "im Wesentlichen parallel" soll hier insbesondere eine Ausrichtung einer Richtung relativ zu einer Bezugsrichtung, insbesondere in einer Ebene, verstanden werden, wobei die Richtung gegenüber der Bezugsrichtung eine Abweichung insbesondere kleiner als 8°, vorteilhaft kleiner als 5° und besonders vorteilhaft kleiner als 2° aufweist. Besonders bevorzugt verläuft die Hauptführungsachse zumindest im Wesentlichen quer zur Hochachse. Hierbei verläuft die Hochachse in einem an einem Werkstück angeordneten Zustand der die Schleifmaschinengehäusevorrichtung umfassenden Handwerkzeugmaschine zumindest im Wesentlichen senkrecht zu einer Werkstückoberfläche des Werkstücks. Der Ausdruck "im Wesentlichen senkrecht" soll hier insbesondere eine Ausrichtung einer Richtung relativ zu einer Bezugsrichtung definieren, wobei die Richtung und die Bezugsrichtung, insbesondere in einer Ebene betrachtet, einen Winkel von 90° einschließen und der Winkel eine maximale Abweichung von insbesondere kleiner als 8°, vorteilhaft kleiner als 5° und besonders vorteilhaft kleiner als 2° aufweist.

Die Grifffläche ist bei einer ordnungsgemäßen Handhabung der Schleifmaschinengehäusevorrichtung, insbesondere der die Schleifmaschinengehäusevorrichtung umfassenden Handwerkzeugmaschine, bevorzugt als Auflagefläche für eine Handfläche eines Bedieners vorgesehen. Somit verläuft die Hochachse insbesondere zumindest im Wesentlichen senkrecht zu einer Tangente der Grifffläche. Mittels der erfindungsgemäßen Ausgestaltung der Schleifmaschinengehäusevorrichtung kann vorteilhaft eine ergonomisch handhabbare Energiespeicheraufnahmeschnittstelle realisiert werden. Zudem kann vorteilhaft eine platzsparende Anordnung der Energiespeicheraufnahmeschnittstelle im Bereich einer Partikelauffangbehälterschnittstelle der Schleifmaschinengehäusevorrichtung erreicht werden. Insbesondere kann besonders vorteilhaft ein komfortables Anordnen einer Partikelauffangvorrichtung an der Partikelauffangbehälterschnittstelle in einem an der Energiespeicheraufnahmeschnittstelle angeordneten Zustand der Energiespeichervorrichtung ermöglicht werden.It is further proposed that the grinding machine housing device comprises at least one vertical axis with which a receiving guide plane of the energy storage receiving interface, in which the main guide axis runs, encloses an angle that is smaller than 80 °. In particular, the vertical axis and the receiving guide plane enclose an angle which is smaller than 60 °, preferably smaller than 40 ° and particularly preferably smaller than 32 °. The angle is preferably measured on a side of the receiving guide plane facing the housing element. In addition, the angle is preferably measured in an area facing a tool holder between the holder guide plane and the vertical axis. The vertical axis preferably runs in the plane of the input and output axes. In particular, the vertical axis extends at least substantially parallel to a main direction of extent of the Housing elements. In this case, the vertical axis particularly preferably runs at least essentially parallel to the drive axis of the drive unit, at least in a state of the drive unit arranged on the housing element. "Essentially parallel" is to be understood here to mean in particular an alignment of a direction relative to a reference direction, in particular in a plane, the direction having a deviation from the reference direction, in particular less than 8 °, advantageously less than 5 ° and particularly advantageously less than 2 °. The main guide axis particularly preferably runs at least substantially transversely to the vertical axis. In this case, in a state of the handheld power tool comprising the grinding machine housing device, which is arranged on a workpiece, the vertical axis runs at least substantially perpendicular to a workpiece surface of the workpiece. The term "essentially perpendicular" is intended here to define, in particular, an alignment of a direction relative to a reference direction, the direction and the reference direction, particularly viewed in a plane, enclosing an angle of 90 ° and the angle including a maximum deviation of, in particular, less than 8 °, advantageously less than 5 ° and particularly advantageously less than 2 °.

When the grinding machine housing device is properly handled, in particular the handheld power tool comprising the grinding machine housing device, the gripping surface is preferably provided as a support surface for the palm of an operator. The vertical axis thus runs in particular at least substantially perpendicular to a tangent of the gripping surface. By means of the design of the grinding machine housing device according to the invention, an ergonomically manageable energy storage receiving interface can advantageously be implemented. In addition, a space-saving arrangement of the energy storage receiving interface in the area of a particle collecting container interface of the grinding machine housing device can advantageously be achieved. In particular, a convenient arrangement of a particle collecting device at the particle collecting container interface can be made possible in a particularly advantageous manner in a state of the energy storage device which is arranged at the energy storage receiving interface.
Ferner wird vorgeschlagen, dass die Energiespeicheraufnahmeschnittstelle an einer Längsseite des Gehäuseelements angeordnet ist. Die Längsseite des Gehäuseelements weist bevorzugt eine Haupterstreckung auf, die entlang einer zumindest im Wesentlichen parallel zur An- und Abtriebsachsenebene verlaufenden Richtung verläuft. Vorzugsweise weist die Längsseite des Gehäuseelements im Vergleich zu weiteren Seiten des Gehäuseelements die größte Gesamterstreckung auf. Mittels der erfindungsgemäßen Ausgestaltung kann besonders vorteilhaft eine Anordnung der Energiespeicheraufnahmeschnittstelle nahe eines Schwerpunkts der Schleifmaschinengehäusevorrichtung, insbesondere eines Schwerpunkts der die Schleifmaschinengehäusevorrichtung umfassenden Handwerkzeugmaschine, erreicht werden. Somit kann vorteilhaft eine komfortable Bedienbarkeit der die Schleifmaschinengehäusevorrichtung umfassenden Handwerkzeugmaschine ermöglicht werden.

Somit weist das Befestigungselement bevorzugt eine Befestigungsachse auf, die zumindest im Wesentlichen parallel zur Hauptführungsachse des Aufnahmeführungselements verläuft. Insbesondere wirkt zumindest ein Großteil einer Befestigungskraft zu einer Befestigung der Energiespeicheraufnahmeschnittstelle am Gehäuseelement entlang der Befestigungsachse des Befestigungselements. Es ist jedoch auch denkbar, dass das Befestigungselement eine Haupterstreckung aufweist, die zumindest im Wesentlichen quer zur Hauptführungsachse des Aufnahmeführungselements verläuft. Mittels der erfindungsgemäßen Ausgestaltung der Schleifmaschinengehäusevorrichtung kann vorteilhaft eine konstruktiv einfache Montierbarkeit der Energiespeicheraufnahmeschnittstelle erreicht werden, insbesondere bei einer Ausgestaltung der Schleifmaschinengehäusevorrichtung in Schalenbauweise. Zudem kann eine vorteilhafte Wirkrichtung einer Befestigungskraft erreicht werden, die entgegen einer Einschubrichtung der Energiespeichervorrichtung gerichtet ist. Somit kann besonders vorteilhaft eine stabile Anordnung der Energiespeicheraufnahmeschnittstelle am Gehäuseelement erreicht werden.It is also proposed that the energy storage receptacle interface comprises at least one assembly area which has at least one fastening element for fastening the energy storage receptacle interface to the housing element, which, viewed in a state mounted on the housing element, has a fastening axis running at least substantially transversely to the plane of the input and output axes. Thus, the fastening element preferably has a fastening axis which runs at least substantially parallel to the main guide axis of the receiving guide element. In particular, at least a large part of a fastening force acts to fasten the energy storage receiving interface on the housing element along the fastening axis of the fastening element. However, it is also conceivable that the fastening element has a main extension which runs at least substantially transversely to the main guide axis of the receiving guide element. By means of the design of the grinding machine housing device according to the invention, it is advantageously possible to achieve a structurally simple assembly of the energy storage receiving interface, in particular when the grinding machine housing device is designed in a shell construction. In addition, an advantageous effective direction of a fastening force can be achieved which is opposite to an insertion direction of the energy storage device is directed.

Mittels der erfindungsgemäßen Ausgestaltung kann vorteilhaft eine weitgehende Schwingungsentkopplung der Energiespeicheraufnahmeschnittstelle erreicht werden, insbesondere von Schwingungen der Antriebseinheit. Somit kann eine bauteilschonende Anordnung einer Energiespeichervorrichtung an der Energiespeicheraufnahmeschnittstelle ermöglicht werden.It is further proposed that the grinding machine housing device comprises at least one damping unit which is arranged at least between the housing element and the energy storage receiving interface. A “damping unit” is to be understood here in particular as a unit which comprises at least one component which is preferably provided to reduce the transmission of vibrations from the housing element to the energy storage receiving interface.
