Description

Technical Field

[0001] The invention relates to an operating unit, a locking unit and a clamping unit for a handheld power tool. Background Art

[0002] DE 10 2015 226 423 A1 is based on a handheld power tool, in particular a drill and / or a chiseling hammer, which has at least one battery and at least one battery interface for mechanically receiving the battery. The handheld power tool has at least one active clamping unit, which is provided for clamping the battery in the operating position in or on the battery interface. Summary of the invention

[0003] The invention is based on the object of improving a hand-held power tool, in particular an actuating unit, a locking unit and / or a clamping unit, by means of simple structural measures.

[0004] This object is achieved by an actuating unit for releasing a battery device for a handheld power tool, the actuating unit having a blocking element for blocking the actuating unit and having an actuating element which is provided to move the blocking element so that the actuating unit is transferred from a holding state to a released state.

[0005] According to the invention, the blocking element is held in the released state in a form-fitting and / or non-positive manner.

[0006] As a result, the battery device can be released or released from the handheld power tool in a particularly advantageous manner, for example, by actuating the actuating unit by means of an actuating element on the handheld power tool. For example, in the case of a particularly heavy or bulky battery device, it can be expedient to release the battery device before removal. In this case, preparations can be made for removing the battery device from the handheld power tool by moving the actuating unit into a released state in which the battery device is not locked or clamped relative to the handheld power tool. As a result, the operator of the handheld power tool can focus solely on removing the battery device without having to perform any other actuations.

[0007] In order to also be able to supply high-power handheld power tools, battery devices are becoming larger and heavier. Due to the increasing energy demand in battery applications, battery devices may have to be charged and replaced frequently. For example, battery applications can also be set up that require the replacement of battery devices at intervals of 5 minutes. With the help of the present invention, battery devices that are especially heavy, bulky and / or not convenient to hold can be replaced particularly conveniently and can be more advantageous for the operator. For example, if the operator of the handheld power tool can loosen the battery device from the handheld power tool independently of the operation of the operating unit, preferably by one-handed operation, the battery device can be replaced ergonomically and conveniently. This is achieved in the following way: the operating unit can be configured in the released state to keep the battery device clamped or clamped, locked in the relaxed state, unlocked state.

[0008] Thus, the invention allows the actuation of the actuation unit, in particular the locking unit and / or the clamping unit, to be held in the released state. The actuation unit, in particular the locking unit and / or the clamping unit, can transition from the released state to the held state, in particular automatically, in accordance with the receiving process and / or relative movement of the battery device, in particular in order to clamp and / or lock the battery device on the handheld power tool.

[0009] The released state of the operating unit can in particular form a bistable state in which, when the operating unit is operated, the operating unit remains in the released state at least for a limited time.

[0010] Preferably, the operating unit can be designed such that the operating unit can be transferred from the holding state to the release state by, for example, an operator's operation. Most preferably, the operating unit can be designed such that the operating unit can be transferred from the release state to the holding state by an operation of the battery device, in particular during the receiving process of the battery device with the handheld power tool.

[0011] The handheld power tool may be, in particular, a hammer drill, a screwdriver, a circular saw or another machine which appears to be appropriate to a person skilled in the art.

[0012] Other uses of such an actuating unit which appear to be appropriate to a person skilled in the art may also be suitable, for example use in electric bicycles or in dust extraction devices for handheld power tools.

[0013] An “operating element” is to be understood as meaning, in particular, an element which is provided to receive input variables from an operator during an operating process and which is in particular directly contacted by the operator, wherein a touching of the operating element is sensed and / or an operating force applied to the operating element is sensed and / or mechanically transmitted for operating a unit.

[0014] A “holding state” is to be understood as a state which exists in particular in an inoperative state or a non-clamped or partially clamped state of the actuating unit, in particular the blocking element. The holding state can form the bottom dead center of the movement of the actuating unit, in particular the actuating element.

[0015] A “released state” is to be understood as a state in which the operating unit, in particular the blocking element, is arranged in a state moved away from the inoperative state of the operating unit and is in particular in a clamped or at least partially clamped state. The released state can be provided to release the battery device relative to the handheld power tool in that an operator of the handheld power tool blocks the movement of the blocking element.

[0016] The holding state and / or the releasing state constitute, in particular, an actuating state of the actuating unit.

[0017] The blocking element can be configured as a blocking pin. The blocking element can be configured as a blocking pin. The blocking element can be configured to limit, in particular form-lockingly limit or prevent a relative movement of the operating unit, in particular the operating element, at least in the released state. The blocking element can be supported movably relative to the operating element. The blocking element can be supported in or on the operating element in a preloaded or spring-loaded manner. The blocking element can be supported movably along a first direction of movement. The operating element can be supported movably along a second direction of movement. The first direction of movement can be oriented transversely to, in particular perpendicularly to, the second direction of movement.

[0018] The present application also describes expedient further embodiments of the operating unit according to the invention.

[0019] Control unit

[0020] It can be expedient that the actuating element is prestressed in at least the released state, in particular by means of a first spring element, in particular in order to exert a force on the actuating element and / or the blocking element and to adjust the actuating element from the released state into the holding state. The first spring element can be clamped in the released state. The first spring element can be partially clamped or not clamped in the holding state. This can ensure that the actuating unit can be reset in a particularly simple and reliable manner.

[0021] Furthermore, it can be expedient for the blocking element to be prestressed in at least the released state, in particular by means of a second spring element, in particular in order to exert a force on the blocking element and to hold the blocking element in the released state, in particular in a force-locking and / or form-locking manner. In particular, the actuating unit can be held in the released state by means of the force action of the first spring element and the force action of the second spring element. The first spring element and the second spring element can be designed as tension springs or compression springs or other spring elements that are considered suitable by a person skilled in the art. As a result, the blocking element can be held in the released state particularly reliably.

[0022] A “spring element” is to be understood in particular as a macroscopic element which has at least one extension which can change elastically in the normal operating state by at least 10%, in particular by at least 20%, preferably by at least 30% and particularly advantageously by at least 50% and which generates a reaction force which is particularly dependent on the change in the extension and is preferably proportional to the change, and which counteracts the change. The “extension” of an element is to be understood in particular as the maximum distance between two points of the perpendicular projection of the element onto a plane, which is in particular at least 1 mm, in particular at least 5 mm and preferably at least 10 mm.

[0023] In addition, it can be suitable that the operating unit has a control element, which is arranged to hold the blocking element in a released state or a held state by means of a first spring element and / or a second spring element. In addition, it can be suitable that the control element has a stop surface, which is arranged to hold the blocking element in a released state in a form-locked and / or force-locked manner. The control element can form a control contour. The control element can be configured as a control groove or a control protrusion. The control element can be configured as a guide groove, which is particularly arranged to guide the blocking element. The control element can be arranged to limit the relative movement of the blocking element, in particular in a form-locked manner, preferably by means of a stop surface. The control element can be arranged in a housing, in particular in a housing of a handheld power tool or a battery device. The control element can have two guide surfaces. The guide surfaces can be arranged parallel to each other. The guide surfaces can be arranged spaced apart from each other. The guide surfaces can be separated by a stop surface. The stop surface can be arranged transversely to, in particular perpendicularly to, at least one of the guide surfaces. The guide surfaces can be arranged at different height levels. Overcoming the height level from one guide surface to the second guide surface can be achieved in that the blocking element is moved, for example by the battery device, in order to overcome the height difference. As a result, the blocking element can be held in the control element in a particularly compact and reliable manner.

[0024] It is proposed that the blocking element can be transferred from a release state to a retaining state as a function of a relative movement of the battery device, in particular a receiving process. In particular, the battery device can be configured to indirectly or directly actuate or contact the blocking element so that the blocking element is transferred from the release state to the retaining state. As a result, the actuation unit can be transferred from the release state to the retaining state in a particularly advantageous manner during the receiving process of the battery device.

[0025] A “receiving process” is to be understood as a process of receiving, in particular connecting, preferably inserting, the rechargeable battery device on or in the handheld power tool. A receiving process is to be understood in particular as a process of inserting the rechargeable battery device into the handheld power tool.

[0026] It is also proposed that the operating unit has a coupling element, which is arranged to contact the blocking element in the released state. The coupling element can be arranged in the control element in at least one state. The coupling element can be supported movably relative to the blocking element and / or the control element. The coupling element can be supported movably relative to the operating element. The relative movement of the coupling element, in particular the coupling element, can be limited by the blocking element and / or the battery device in the released state. The coupling element can be arranged to directly contact the blocking element and / or the battery device in at least the released state.

[0027] In particular, a first release state can be set, which holds the blocking element in the release state. Preferably, a second release state can be set, which holds the blocking element in the release state. In the first release state, the blocking element can be held in a shape-locked and / or force-locked manner relative to the coupling element. In the first release state, the blocking element can be held in a shape-locked and / or force-locked manner relative to the coupling element. In the first release state, the blocking element can be held in a shape-locked and / or force-locked manner relative to the stop surface of the control element, in particular the control element. The blocking element can be preloaded more strongly in the first release state than in the second release state, in particular by means of the first and / or second spring element.

[0028] The coupling element, in particular the relative movement of the coupling element, can be limited by the storage battery device in the first released state. The coupling element, in particular the relative movement of the coupling element, can be limited by the blocking element in the second released state.

[0029] It is further proposed that the operating unit has a / the coupling element, which is configured to transfer the blocking element from the release state to the holding state. In particular, the coupling element can counteract the second spring element, in particular the spring action of the second spring element, in the receiving state, in particular in order to transfer the blocking element from the release state to the holding state. The "receiving state" is to be understood in particular as a state in which the battery device is received on the handheld power tool. As a result, the operating unit can be automatically transferred to the holding state when the battery device is received by the handheld power tool.

[0030] It can be suitable that the battery device, in particular the trigger element of the battery device, is configured to apply the release force indirectly or directly to the blocking element so that the blocking element can be shifted from the release state to the holding state. In particular, the blocking element can be shifted from the release state to the holding state by the release force acting on the operating element.

[0031] Furthermore, it may be suitable that the coupling element / the coupling element is / are arranged to apply a release force to the blocking element in such a way that the blocking element can be shifted from a released state to a retained state. The release force can in particular counteract the second spring element in order to shift the blocking element from a released state to a retained state. In particular, the blocking element can be shifted from a released state to a retained state by means of a release force acting on the operating element. Furthermore, it may be suitable that the coupling element is / are arranged to move the coupling element by means of a battery device that is movable relative to the coupling element, in particular in such a way that the coupling element applies a release force to the blocking element. Thus, the released state of the operating unit can be provided in a simple and intuitive manner in order to release the battery device from the handheld power tool or to connect it to the handheld power tool.

[0032] Furthermore, it may be expedient for the coupling element to be arranged on a side of the blocking element facing away from the second spring element.

[0033] It can also be expedient for the coupling element to be spherical or conical, wherein the coupling element is supported at least movably relative to the blocking element. The coupling element can have a T-shaped cross section. The coupling element can be at least substantially pin-shaped.

[0034] Furthermore, it can be expedient for the coupling element to protrude at least in sections relative to the handheld power tool. The coupling element can delimit the handheld power tool. The coupling element can protrude from the housing, in particular the housing of the handheld power tool or the battery device, in at least one state. The coupling element can protrude relative to the housing, in particular the housing of the handheld power tool or the battery device.

[0035] The invention further relates to a handheld power tool having an actuation unit and a locking unit for locking a rechargeable battery device on the handheld power tool.

[0036] It may be expedient for the locking unit to have a locking element which is provided for locking the rechargeable battery device relative to the handheld power tool, in particular in a form-fitting manner. The locking element is provided in particular for preventing a movement of the rechargeable battery device in the holding state of the actuation unit.

[0037] The invention further relates to a handheld power tool having an actuation unit and a clamping unit for clamping a rechargeable battery device on the handheld power tool.

[0038] It may be expedient for the clamping unit to have a clamping element which is provided for clamping the rechargeable battery device relative to the handheld power tool, in particular for clamping it in a force-locking manner. The clamping element is provided in particular for preventing a movement of the rechargeable battery device in the holding state of the actuating unit.

[0039] Locking unit

[0040] The present invention also relates to a locking unit for locking a battery device on a handheld machine tool, which has a locking element and an operating element supported movably relative to the locking element, the locking element being used to lock the battery device relative to the handheld machine tool, in particular in a form-fitting manner, and the operating element being arranged to move the locking element from a locked state of the locking unit to an unlocked state.

[0041] It may be expedient for the actuating element to have a first guide element, in particular a guide groove, which is provided for moving the locking element from the locked state into the unlocked state.

[0042] As a result, the rechargeable battery device can be held particularly advantageously on the handheld power tool by being locked by means of the locking element in the held state of the operating unit.

[0043] Thus, the locking element can be coupled to the operating unit, in particular the operating element. The locking element can be supported movably relative to the operating element. The locking element can be coupled to the operating element. The operating unit, in particular the operating element, can be provided for transferring the locking element from the unlocked state to the locked state, or vice versa, in particular by means of the operating unit.

[0044] The guide element is preferably provided for coupling the operating unit, in particular the operating element, to the locking element. The guide element is particularly provided for applying a force to the locking element in order to shift the locking element from the unlocked state to the locked state. When the operating element is operated, it is provided that the locking element is moved by means of the guide element.

[0045] It may be suitable that the locking element is configured as a locking pin. The locking element may have a circular or polygonal, in particular a square or rectangular cross section. This allows for reliable locking in a particularly simple manner.

[0046] Furthermore, it can be expedient for the locking unit to have a locking notch arranged in the battery device. The locking notch can be configured as a locking groove. The locking notch can be configured as a locking recess. The locking notch can be arranged in a housing, in particular in a housing of a handheld power tool or of the battery device. The housing can in particular be configured as an outer housing. The locking notch can extend transversely, in particular vertically, relative to the receiving direction of the battery device. Reliable locking can thereby be achieved.

[0047] Furthermore, it can be expedient for the locking element to be connected to the battery device in a form-fitting manner, in particular to hold the battery device in or on the handheld power tool in a form-fitting manner opposite to the receiving direction of the battery device. The locking element is particularly provided to prevent a movement of the battery device in the locked state of the locking unit. The actuating unit can be provided to lock the locking unit in accordance with a receiving travel, in particular an insertion travel, of the battery device into the handheld power tool.

[0048] Furthermore, it can be suitable that the locking element is supported movably relative to the handheld power tool, in particular the machine housing of the handheld power tool, and relative to the operating element. The locking element can be supported movably relative to the operating element in particular. The locking element can be supported in a manner that it can be moved from the unlocked state to the locked state transversely, in particular perpendicularly, to the receiving plane. The handheld power tool can limit a first relative movement of the locking element. The operating element can limit a second relative movement of the locking element. The first relative movement can be oriented transversely to the second relative movement. In this way, a particularly simple locking element can be constructed.

[0049] It is proposed that the locking element protrudes relative to the handheld power tool, in particular the machine housing of the handheld power tool, at least in the locked state. In an alternative embodiment, the locking element can protrude relative to the battery device, in particular the battery housing of the battery device, at least in the locked state. This can ensure particularly reliable locking.

[0050] In addition, it is proposed that the locking unit has a second guide element, in particular a second guide groove. The second guide element, in particular the second guide groove, can be constructed transversely to, in particular perpendicularly to, the first guide element, in particular the first guide groove. The second guide element, in particular the second guide groove, can be arranged in a hand-held machine tool, in particular in a machine housing of the hand-held machine tool. It is further proposed that the first guide element, in particular the first guide groove, and the second guide element, in particular the second guide groove, are each constructed as an elongated hole. The guide groove extends in a straight line. The second guide groove can extend transversely to, in particular perpendicularly to, the receiving plane of the battery device. The first guide groove can extend substantially in a direction along the receiving plane. Reliable locking can thereby be achieved.

[0051] The receiving plane should form a plane that extends at least substantially along the receiving direction of the battery device for connecting the battery device to the handheld power tool. For this purpose, the handheld power tool can have a guide device that is provided to form an introduction movement of the battery device along the receiving plane with a guide device of the battery device, in particular a guide rail.

[0052] It can be expedient for the locking element to be supported on the first guide groove and the second guide groove by means of a guide pin designed as a transverse securing pin. The guide groove can be provided to cause a relative movement of the locking element relative to the handheld power tool. The guide groove can be provided to exert a forced movement on the guide pin. The guide pin can be supported movably, in particular rotatably, relative to the guide element. The locking element can thereby be controlled particularly advantageously.

[0053] Furthermore, it may be expedient for the locking element to be mounted so that it can move transversely, in particular perpendicularly, to a receiving plane of the rechargeable battery device.

[0054] In addition, it can be suitable that the operating element is configured as an operating button. The operating element can be provided to shift the locking element into the unlocked state in the operating state of the operating unit, especially the released state. The operating element can be provided to shift the locking element into the locked state in the holding state, especially the holding state of the operating unit.

[0055] In an alternative embodiment, the actuation unit and / or the locking unit can be arranged in the battery device, so that the locking unit can connect the battery device to the handheld power tool similarly to the above-described features. As a result, the handheld power tool can be designed to be particularly compact.

[0056] The invention further relates to a handheld power tool having a locking unit and an actuating unit for releasing a battery device for the handheld power tool.

[0057] Clamping unit

[0058] The invention further relates to a clamping unit for clamping a battery device on a handheld power tool, comprising a clamping element for clamping the battery device and an actuating element movably mounted relative to the clamping element, the actuating element being provided for moving the clamping element from a released state of the clamping unit into a clamped state.

[0059] It may be expedient for the actuating element to be provided for transferring the clamping element from the clamped state into the released state by means of a relative movement.

[0060] The relative movement can result in a translational movement and / or a rotational movement.

[0061] As a result, the battery device can be connected to the handheld power tool in a particularly advantageous manner by being clamped to the handheld power tool by means of the operating element. In particular, the battery device can be clamped to the handheld power tool in a particularly reliable manner without gaps. By means of such clamping, it can be ensured that, even when using heavy battery devices, the battery device does not become loose from the handheld power tool or is not subject to high wear due to gaps or vibrations. In particular, the clamping element is provided for movement relative to the battery device in order to bring about a clamping force acting on the battery device and to clamp the battery device in or on the clamping unit.

[0062] As a handheld power tool, a hammer drill is particularly suitable. In particular, a hammer drill is used for processing rock and has a high impact energy in order to locally break and fracture the rock to be processed. The high impact energy not only causes high vibration loads, especially on the parts of the hammer drill that are movably supported or have gaps, such as conventional battery devices. The broken rock can be distributed in the air, especially as drilling dust, and fall onto the parts that are movably supported or have gaps, such as battery devices and handheld power tools, and has an abrasive effect, especially on mechanical contacts and electrical contacts.

[0063] The relative movement can in particular form a rotational movement. The rotational movement can be formed, for example, by an eccentric movement by means of a circular eccentric drive. The rotational movement can be formed, for example, by means of a toggle lever drive. Thus, the drive can be used to amplify the force in order to transfer the clamping unit from the relaxed state into the clamped state.

[0064] In this context, a “clamping element” is to be understood as an element which, in at least one clamped state, has a form fit relative to the battery device, in particular in at least one direction, and is provided to hold the battery device in a force-fitting manner in the clamped state. In addition to the force fit, the battery device can also have a form fit in other directions.

[0065] The clamping element can be arranged on the handheld power tool. The clamping element can be arranged on the battery device. The clamping element can be clamped relative to the battery device by means of a transmission and in particular form a clamped state. The clamping element can directly contact the battery device. The clamping element can be arranged to hold the battery device on the handheld power tool at least in the clamped state. The clamping element can be arranged to extend into the battery device, in particular into a receiving area of ​​the battery device, at least in the clamped state.

[0066] The clamping element can be provided for clamping the rechargeable battery device in a direction transverse to the rechargeable battery device along a / the receiving direction of the handheld power tool.

[0067] In particular, the clamping unit can be designed in addition to the locking unit, so that the clamping unit and the locking unit clamp and lock the rechargeable battery device relative to the handheld power tool in a state.

[0068] A “clamped state” is to be understood as meaning a state in which the clamping element clamps the rechargeable battery device relative to the handheld power tool by, for example, pressing the rechargeable battery device against the handheld power tool.

[0069] A “relaxed state” is to be understood as a state in which the clamping element supports the rechargeable battery device relative to the handheld power tool in such a way that the rechargeable battery device is not clamped relative to the handheld power tool or has a gap.

[0070] It may be expedient if the clamping element is provided to hold the battery device in a clamped state in a form-fitting and / or force-fitting manner on a clamping unit, in particular a clamping unit of a handheld power tool, so that the battery device can be held without play on the handheld power tool.

[0071] Furthermore, it may be expedient for the clamping element to be rotatably supported on the handheld power tool, in particular on the machine housing of the handheld power tool. The operating element may be provided to couple the clamping element to the operating element. The operating element may be coupled by means of the clamping element in such a way that a translational movement of the operating element causes a rotational movement of the clamping element. The clamping unit may have two clamping elements. The clamping elements may be arranged opposite to each other. The clamping elements may be spaced apart from each other. The clamping elements may be provided to at least partially surround the battery device from two opposite sides.

[0072] Furthermore, it can be expedient for the actuating element to be prestressed in the relaxed state and at least partially prestressed in the tightened state by means of a spring element, in particular a compression spring element. This ensures that the battery device is connected to the handheld power tool in the inserted state.

[0073] Furthermore, it may be expedient for the clamping element to be of U-shaped design. The clamping element may have a clamping extension. The clamping extension is provided for surrounding the battery device. As a result, the battery device can be held particularly reliably.

[0074] It is proposed that the clamping element, in particular the clamping extension, is designed in a wedge shape. The clamping element can have a clamping surface, which is arranged transversely to the receiving plane. The clamping surface can be oriented transversely to the receiving direction and / or transversely to an orthogonal line of the receiving direction of the battery device. The clamping surface can be provided for clamping the battery device. The clamping surface can be provided for orienting the battery device and placing it relative to, for example, a guide rail of the battery device. In this way, even in the case of increased wear, it is possible to ensure precise positioning and prestressing of the battery device. In this way, the battery device can also be clamped from three spatial directions.

[0075] In addition, it is proposed that the clamping element is arranged in at least one notch, in particular a guide notch, of the handheld power tool and surrounds the battery device at least in sections. In particular, the clamping extension can be arranged in at least one notch, in particular a receiving notch, of the battery device and surrounds the handheld power tool at least in sections.

[0076] The handheld power tool may have a receiving unit for receiving a battery device. The receiving unit may have a receiving projection configured as a guide rail for receiving the battery unit. The receiving unit may have a receiving notch configured as a guide notch. The receiving notch may be provided for receiving the receiving projection in an inserted state of the battery device. The receiving projection may be provided for holding the battery device on the handheld power tool in a form-locking manner. The receiving notch may be provided in the handheld power tool or the battery device. The receiving projection may be provided in the handheld power tool or the battery device.

[0077] The clamping continuation can form a receiving projection at least in sections.

[0078] It is further proposed that the clamping element at least partially forms a guide projection, in particular designed as a guide rail, for guiding the battery device. The guide projection can at least partially surround the clamping element. The guide projection can delimit the clamping element from two sides facing away from each other. The clamping element can be arranged between two guide projections in order to preferably separate them. The clamping element can serve as an extension of the guide projection.

[0079] Furthermore, it is proposed that the clamping element, in particular the clamping extension, is arranged in a bearing notch of the guide rail in the receiving state. The clamping element, in particular the clamping extension, can be supported movably in the notch of the guide rail. The notch in the guide projection can be designed as a recess. The notch in the guide projection can be provided for separating the first guide projection from the second guide projection. The notch in the guide projection can be provided for receiving the clamping element, in particular the clamping extension, at least in the removal state. This allows the clamping unit to be designed particularly compactly.

[0080] In particular, the receiving projection is provided for guiding the rechargeable battery device from a removed state into a received state.

[0081] Furthermore, it may be expedient if the clamping element, in particular the clamping extension, is provided to enlarge the extent of a / the guide rail in the clamped-in state of the battery device, in particular transversely to the insertion direction of the battery device, thereby enabling secure reception of the battery device.

[0082] In addition, it can be suitable that the clamping element can be shifted from a relaxed state to a clamped state relative to the operating element by means of a toggle unit. The toggle unit can be operatively connected to the operating element. In addition, it can be suitable that the toggle unit has an toggle element, which connects the operating element to the clamping element and is supported movably relative to them. The toggle element can be supported in a manner that can move relative to the clamping element and / or the operating element. The toggle element can be provided to convert the movement of the operating element, especially the translational movement, into the movement of the clamping element, especially the rotational movement and / or the translational movement. The toggle element is rotatable relative to the operating element and / or rotatably supported relative to the clamping element, especially around the first operating rotation axis. The clamping rotation axis and the operating rotation axis can be arranged to be spaced apart from each other and especially parallel to each other. Thus, a large stroke under a small pulling force or pressure can be converted into a short stroke with a large force, or vice versa.

[0083] Also conceivable is a circular eccentric disk which clamps the clamping element relative to the actuating element.

[0084] It is proposed to provide two clamping elements which preferably surround the battery device symmetrically at least in sections and in particular act in opposite directions to one another. Alternatively, it is also possible to provide clamping elements which preferably surround the battery device asymmetrically at least in sections.

[0085] Furthermore, it is proposed that the clamping element clamps the rechargeable battery device in a force-locking manner transversely, in particular perpendicularly, to a receiving direction of the rechargeable battery device.

[0086] The invention further relates to a rechargeable battery device having a locking element, in particular a snap-in element, which has a locking unit and a clamping unit for locking the rechargeable battery device to a handheld power tool.

[0087] The invention further relates to a handheld power tool, in particular a hammer drill, having a receiving unit designed as a receiving rail for releasably receiving a rechargeable battery device and having the above-described clamping unit.

[0088] The invention further relates to a handheld power tool system having a handheld power tool and a rechargeable battery device, comprising a clamping unit and a locking unit for locking the rechargeable battery device to the handheld power tool.
