Definitions
- the present invention relates to a battery-operated hand machine tool with a battery interface, which is arranged on a housing of the hand machine tool.
- the battery interface is designed to make electrical contact with a battery unit for operating the handheld power tool.
- Handheld power tools of the type mentioned at the outset are generally known from the prior art, for example in the form of cordless rotary hammers, cordless chisel hammers or cordless combination hammers. These are supplied with electrical current by a rechargeable battery unit, which can be detachably received or recorded at the battery interface. The power transmission from the battery unit to the hand tool takes place via the battery interface.
- the invention is achieved in that the battery interface is coupled to the housing so that it can move by at least one degree of freedom with respect to the housing.
- the invention includes the finding that a rechargeable battery unit that is accommodated in a battery-operated hand-held power tool of the prior art is only insufficiently secured against undesired falls. In the event of a fall, the entire effective fall energy must be absorbed by the battery unit itself, which often leads to destruction of the battery unit - or at least to its functional impairment. Battery units are known from the prior art, in which a housing of the battery unit absorbs part of the fall energy.
- a hand-held power tool is provided, the battery interface of which can be moved with respect to the housing of the hand-held power tool, so that a falling energy, at least in the direction of a degree of freedom, is not transmitted to the rechargeable battery unit via a rigid coupling or directly from the housing of the hand-held power tool. This creates the basis for increased operational safety of a battery-operated hand tool.
- the degree of freedom achieved by the decoupling is oriented parallel to a tool axis, in particular parallel to a flapping axis of the hand tool.
- an impact energy desired during operation is advantageously not transmitted to the rechargeable battery unit via a rigid coupling or directly from the housing of the handheld power tool.
- the handheld power tool is particularly preferably designed as a combination hammer, chisel hammer or rotary hammer.
- the battery interface is coupled to the housing via a slide guide. It has proven to be advantageous if the slide guide is designed as a linear slide guide.
- a guide element of the slide guide can be formed in one piece with the housing, for example by injection molding.
- the battery interface is cushioned against the housing, preferably by means of a prestressed spring element.
- the spring element can be designed, for example, as a leaf spring.
- the battery interface can be damped against the housing, preferably by means of a damper element.
- the spring element and the damper element are preferably arranged on opposite sides of the battery interface with respect to the tool axis.
- the handheld power tool has a receiving bay which completely encompasses the battery interface.
- the battery interface according to the invention - as a protective measure for the battery unit - can be accommodated completely within the receiving bay of the handheld power tool intended for the battery unit. This means that external design changes or any increase in installation space for the handheld power tool are not necessary. The battery unit itself can remain unchanged.
- the battery unit can only be mechanically coupled or coupled to the handheld power tool via the movable battery interface. It has proven to be advantageous if the battery interface is coupled to the housing so that it can be moved by exactly one degree of freedom with respect to the housing.
- the battery interface can only be designed to be translationally movable, preferably only parallel to the tool axis.
- the invention is also achieved by a system with a battery-operated hand machine tool of the type described above and with at least one battery unit is designed for releasable recording at the battery interface of the hand tool.
- the handheld power tool can have a receiving bay for receiving the battery unit, wherein battery units of different sizes (capacity) can be received.
- the spatial extent of the receiving bay is preferably fixed, ie in particular the same size for battery units of different sizes.
- FIG Fig. 1 A particularly preferred exemplary embodiment of a battery-operated hand-held power tool 100 according to the invention is shown in FIG Fig. 1 shown.
- Handheld power tool 100 is equipped with a battery interface 10, which is arranged on a housing 90 of handheld power tool 100, which is only partially shown here.
- the battery interface 10 is designed to be releasably received and to make electrical contact with a battery unit 200 for operating the handheld power tool 100.

- the battery interface 10 - due to the battery unit 200 that has been accommodated - can only be recognized in a hint.
- the battery unit 200 in the present case having two stacked battery layers 201, is received in a receiving bay 80 of the handheld power tool 100.
- the battery interface 10 is completely encompassed by the receiving bay 90, more precisely by a receiving volume V defined by the receiving bay 90 (shown in dashed lines).
- Fig. 1 Easy to recognize in Fig. 1 is that the battery unit 200 with its two stacked battery layers 201 does not extend to a lower edge UK of the housing 90, the lower edge UK simultaneously forming a limitation of the already mentioned receiving volume V of the receiving bay 90.
- the hand machine tool 100 of Fig. 1 is an example designed as a chisel hammer. Accordingly, the tool axis WA, which runs horizontally here, is the flapping axis of the hand tool 100 provided as a chisel hammer.
- the battery interface 10 is coupled to the housing 90 by a degree of freedom F with respect to the housing 90.
- the degree of freedom F realized by the decoupling is oriented parallel to the tool axis WA, which in the present case is an impact axis.
- FIG Fig. 2 the battery interface 10 of the handheld power tool 100 Fig. 1 shows in top view.
- a battery unit 200 with three stacked battery layers 201 is accommodated at the battery interface 10.
- the battery interface 10 is coupled to the housing 90 via a linear slide guide 20.

- the battery interface 10 is suspended as a slide in the guide elements 21, as a result of which the battery interface 10 is coupled to the housing 90 so that it can be moved by exactly one degree of freedom F with respect to the housing 90.
- the exactly one degree of freedom F realized by the decoupling is oriented parallel to the tool axis WA. Due to this horizontal, linear guidance of the battery interface 10, the battery unit 200 received at the battery interface 10 "floats" horizontally to the handheld power tool 100.
- a prestressed spring element 30 in the form of a leaf spring.
- the leaf spring can be made of sheet metal.
- damper element 40 is shown, via which the battery interface 10 is damped against the housing 90.
- the spring element 30 and the damper element 40 with respect to the tool axis WA — are arranged on opposite sides of the battery interface 10.
- the battery unit 200 moved to the left in the course of a striking operation of the handheld power tool 100 is pressed against the spring element 30, as a result of which the latter is tensioned.
- the damper element 40 is not absolutely necessary for the solution according to the invention.
- the damper element 40 can be provided as an alternative or in addition to a counter spring element, not shown here.
- Fig. 2 can also be easily removed, the battery unit 200 is only mechanically coupled to the handheld power tool 100 via the movable battery interface 10. In other words, the battery unit 200 hangs freely on the battery interface 10 which can be moved horizontally here.
- Fig. 3 finally shows the battery interface 10 of the Fig. 2 in view from below, the battery interface 10 being free of a battery unit. It can be clearly seen how the battery interface 10 is suspended as a slide in the guide elements 21, as a result of which the battery interface 10 is coupled to the housing 90 so that it can be moved by exactly one degree of freedom F with respect to the housing 90.
- the guide elements 21 encompass the battery interface 10 as pliers like a slide.

Die Akkuschnittstelle ist zum elektrischen Kontaktieren einer Akkueinheit zum Betreiben der Handwerkzeugmaschine ausgebildet.The present invention relates to a battery-operated hand machine tool with a battery interface, which is arranged on a housing of the hand machine tool. The battery interface is designed to make electrical contact with a battery unit for operating the handheld power tool.
Handwerkzeugmaschinen der eingangs genannten Art sind grundsätzlich aus dem Stand der Technik bekannt, beispielsweise in Form von Akku-Bohrhämmern, Akku-Meisselhämmern oder Akku-Kombihämmern. Diese werden durch eine Akkueinheit, die wiederlösbar an der Akkuschnittstelle aufgenommen oder aufzunehmen ist, mit elektrischem Strom versorgt. Die Stromübertragung von der Akkueinheit zur Handwerkzeugmaschine erfolgt dabei über die Akkuschnittstelle.Handheld power tools of the type mentioned at the outset are generally known from the prior art, for example in the form of cordless rotary hammers, cordless chisel hammers or cordless combination hammers. These are supplied with electrical current by a rechargeable battery unit, which can be detachably received or recorded at the battery interface. The power transmission from the battery unit to the hand tool takes place via the battery interface.
Es ist Aufgabe der vorliegenden Erfindung eine akkubetriebene Handwerkzeugmaschine bereitzustellen, die die Grundlage für eine erhöhte Betriebssicherheit schafft.It is an object of the present invention to provide a battery-operated hand-held machine tool which creates the basis for increased operational reliability.
Die Erfindung wird dadurch gelöst, dass die Akkuschnittstelle um wenigstens einen Freiheitsgrad bezüglich des Gehäuse beweglich mit dem Gehäuse gekoppelt ist.The invention is achieved in that the battery interface is coupled to the housing so that it can move by at least one degree of freedom with respect to the housing.
Die Erfindung schließt die Erkenntnis ein, dass eine Akkueinheit, die in einer akkubetriebenen Handwerkzeugmaschine des Standes der Technik aufgenommen ist, nur unzureichend gegen unerwünschte Stürze gesichert ist. Im Sturzfall muss die gesamte wirksame Fallenergie von der Akkueinheit selbst aufgenommen werden, was häufig zu einer Zerstörung der Akkueinheit - zumindest aber zu ihrer funktionellen Beeinträchtigung - führt. Aus dem Stand der Technik sind Akkueinheiten bekannt, bei denen ein Gehäuse der Akkueinheit einen Teil der Sturzenergie aufnimmt.The invention includes the finding that a rechargeable battery unit that is accommodated in a battery-operated hand-held power tool of the prior art is only insufficiently secured against undesired falls. In the event of a fall, the entire effective fall energy must be absorbed by the battery unit itself, which often leads to destruction of the battery unit - or at least to its functional impairment. Battery units are known from the prior art, in which a housing of the battery unit absorbs part of the fall energy.
In Abkehr vom Stand der Technik wir eine Handwerkzeugmaschine bereitgestellt, deren Akkuschnittstelle bezüglich des Gehäuses der Handwerkzeugmaschine beweglich ist, so dass eine in Fallenergie, zumindest in Richtung eines Freiheitsgrads, nicht über eine starre Kopplung oder unmittelbar von dem Gehäuse der Handwerkzeugmaschine auf die Akkueinheit übertragen. Somit wird die Grundlage für eine erhöhte Betriebssicherheit einer akkubetriebenen Handwerkzeugmaschine geschaffen.In a departure from the prior art, a hand-held power tool is provided, the battery interface of which can be moved with respect to the housing of the hand-held power tool, so that a falling energy, at least in the direction of a degree of freedom, is not transmitted to the rechargeable battery unit via a rigid coupling or directly from the housing of the hand-held power tool. This creates the basis for increased operational safety of a battery-operated hand tool.
In einer besonders bevorzugten Ausgestaltung ist der durch die Entkopplung realisierte Freiheitsgrad parallel zu einer Werkzeugachse, insbesondere parallel zu einer Schlagachse Handwerkzeugmaschine orientiert ist. Vorteilhafterweise wird derart eine im Betrieb erwünschte Schlagenergie, zumindest in Richtung eines Freiheitsgrads, nicht über eine starre Kopplung oder unmittelbar von dem Gehäuse der Handwerkzeugmaschine auf die Akkueinheit übertragen. Besonders bevorzugt ist die die Handwerkzeugmaschine als Kombihammer, Meisselhammer oder Bohrhammer ausgebildet ist.In a particularly preferred embodiment, the degree of freedom achieved by the decoupling is oriented parallel to a tool axis, in particular parallel to a flapping axis of the hand tool. In this way, an impact energy desired during operation, at least in the direction of a degree of freedom, is advantageously not transmitted to the rechargeable battery unit via a rigid coupling or directly from the housing of the handheld power tool. The handheld power tool is particularly preferably designed as a combination hammer, chisel hammer or rotary hammer.
In einer weiteren bevorzugten Ausgestaltung ist die Akkuschnittstelle über eine Schlittenführung mit dem Gehäuse gekoppelt.
