[0004] It is proposed that the holding device has at least one variable unit arranged at least partially on the support element for variably arranging the locking unit at different positions of the support element, in particular viewed along the longitudinal axis of the support element. Due to the configuration of the holding device according to the invention, a high degree of flexibility can be advantageously achieved when mounting the battery on the holding device.

In particular, the holding device is configured to achieve at least temporary positioning of the battery in and / or on the bicycle. In particular, the battery can be simply, preferably tool-free, assembled into or removed from the holding device. In particular, the holding device is configured to be fixed on a bicycle frame, preferably in a bicycle frame, for example in an upper tube, a seat tube, a steering tube or preferably a lower tube of the bicycle frame. In order to be fixed in or on the bicycle frame, the holding device particularly includes a fastening element, such as a screw, a plug-in element or a locking element. Alternatively or additionally, it is conceivable that the holding device, preferably a bracket unit or a bracket element is at least partially configured integrally with the bicycle frame, or that at least a portion of the holding device, preferably a bracket unit or a bracket element is integrally connected to the bicycle frame, for example welded or bonded.

[0006] Preferably, the variation unit is arranged to fix the locking unit at different positions on the support element. Preferably, the variation unit fixes the locking unit on the support element in at least one direction. Preferably, the variation unit fixes the locking unit in a fixed position on the support element. Particularly preferably, the variation unit fixes the locking unit on the support element in a rotationally fixed manner and / or in a fixed position. In particular, the variation unit is arranged to arrange locking units of different configurations on the support element. It is conceivable that the variation unit has a plurality of positions for arranging the locking unit. Preferably, the variation unit comprises at least one element, which is arranged to be connected to the locking unit and / or the support element in a form-locking and / or force-locking manner so as to arrange at least the locking unit position variably on the support element. The elements of the variation unit can be configured as form-locking grooves, as clamping elements, as latching elements or as other elements that seem meaningful to those skilled in the art. Preferably, the variation unit is arranged to cooperate with form-locking elements, such as, for example, latching elements or the like, which are fixedly or movably arranged on the locking unit, in particular, arranged on the base of the locking unit. Preferably, the displacement unit is designed in such a way that the locking unit and / or the stop unit of the holding device can be arranged at different positions on the carrier element.

[0007] In particular, the locking unit is provided for fixing the battery to the support unit. It is conceivable that the locking unit is fastened to the support element. It is also conceivable that the locking unit is fixedly connected to the battery. Preferably, the locking unit fixes the battery to the support element in at least one direction. Preferably, the locking unit fixes the battery in a fixed position on a displacement unit arranged on the support element. Particularly preferably, the locking unit fixes the battery to the support element in a rotationally fixed and / or positionally fixed manner.

[0008] The variable unit can be configured as a locking unit, as a clamping unit, as a tightening unit, as a rail slide unit or as other units that seem meaningful to a person skilled in the art, which are configured to be used to arrange at least the locking unit positionally variably on the support unit by means of a form-locking and / or force-locking connection. Preferably, at least a portion of the variable unit is arranged on the support element, especially constructed in one piece with the support element. It is also conceivable that the variable unit is at least partially arranged on the locking unit. In the configuration of the variable unit as a rail slide unit, the variable unit preferably includes at least one rail slide, which is movably supported on the support element along the longitudinal axis of the support element. Particularly preferably, the variable unit configured as a rail slide unit has at least one locking element arranged on the rail slide, and the locking element is under spring tension. For example, the locking element is configured as a pin or the like. It is also conceivable that the variable unit configured as a rail slide unit has at least one tightening element or clamping element arranged on the rail slide. In particular, the latching element arranged on the rail slide can engage in a corresponding form-fitting element, in particular a latching recess, of the change unit in a defined position of the rail slide on the carrier element. In particular, the change unit configured as a rail slide unit has an actuating unit, which is configured to release the latching element from a locked state when the actuating unit is actuated.

[0009] In addition, it is proposed that the variable unit has at least two form-locking elements, in order to variably arrange the locking unit, in particular along the longitudinal axis of the support element, at different positions of the support element. Thus, a simple and space-saving holding device can be advantageously realized. Particularly advantageously, the locking unit can be arranged at different positions by the configuration according to the present invention. In particular, the form-locking element of the variable unit is arranged for arranging the locking unit. In particular, the form-locking element is arranged for establishing a form lock with at least a part of the locking unit in an operating state. In particular, the form-locking element forms a form-locking groove, which is arranged for receiving a part of the locking unit, in particular a form-locking mating element of the locking unit, in order to establish a form-locking connection. Preferably, the form-locking element is configured as a groove or depression in the variable unit, in particular a groove or depression arranged on the support element. Particularly preferably, the form-locking element of the variable unit is configured as a polygonal, in particular a rectangular groove. It is also conceivable that the form-locking element of the variable unit is configured as an elongated hole, as a circular, egg-shaped, elliptical or other grooves or depressions that seem meaningful to those skilled in the art. It is also conceivable that the form-locking element of the change unit is configured as a groove with different shapes. In particular, the form-locking element can be arranged on any side of the support element or the frame, for example on the right side, left side, top side or bottom side, relative to the placement direction of the frame, in particular the bicycle frame.

[0010] In addition, it is proposed that at least two form-locking elements are arranged along the longitudinal axis of the support element at different spacings from the stop unit of the holding device, especially arranged on the end of the support element. Thus, a holding device that allows the assembly of batteries of different lengths can be advantageously provided. Particularly advantageously, a space-saving holding device can be realized by the configuration according to the present invention. In particular, the stop unit is arranged to limit at least one axial movement of the battery relative to the support unit in the assembly direction or the push-in direction during assembly and / or in an operating state. Preferably, the stop element is connected to the support unit, especially to the support element of the support unit in a force-locked, form-locked and / or material-locked manner. In particular, the battery is clamped, especially clamped and / or stuck between the locking unit and the stop unit in the operating state arranged on the support element. Preferably, the battery is clamped between the stop unit and the locking unit so that the locking unit applies pressure to the battery in the clamped operating state, and the pressure acts toward the stop unit, especially parallel to the longitudinal axis of the support element. Alternatively or additionally, it is conceivable that the holding device comprises an adapter element, which is provided for being clamped between the stop element and the rechargeable battery. Preferably, the adapter element is plated through here to ensure an electrically conductive connection between the rechargeable battery and the stop element.

[0011] It is further proposed that the holding device comprises a locking unit, in particular the locking unit already mentioned above, which is variably arranged on the support unit by means of a displacement unit, wherein the locking unit is provided for removably fastening the battery to the support unit. In particular, it is conceivable that the locking unit is fastened to the displacement unit of the support element and that the battery is clamped, in particular clamped and / or snapped in between the stop unit and the locking unit by radial displacement of the battery. However, it is also conceivable that the locking unit is fixedly arranged on the battery and that the locking unit is arranged in one step on the displacement unit for removably holding the battery on the frame, in particular on the bicycle frame.

[0012] It is further proposed that the holding device comprises, in particular, the previously mentioned battery, wherein the battery has a locking unit for removably fastening the battery to a variable unit arranged on the support element. This advantageously enables the battery to be axially mounted and removed from the holding device. Particularly advantageously, removable holding of batteries of different lengths is achieved by the holding device according to the invention. Preferably, the locking unit is arranged on one side of the battery, in particular on the battery side opposite to the battery side facing the stop unit. Preferably, the locking unit has a clamping unit, which is configured to fix the battery to the support unit in a clamping operating state and to clamp, in particular clamp and / or snap the battery between the locking unit and the stop unit in an operating position, so that in the clamping operating state the clamping unit applies a pressure to the battery, which acts toward the stop unit, in particular parallel to the longitudinal axis of the support element. A "clamped operating state" is to be understood in particular as a state of the holding device in which the clamping unit is clamped, in which the battery is fixed in the holding device and / or in which the battery is in an operating position, that is, in particular, in which the battery outputs energy, for example to an auxiliary motor. It is conceivable that the clamping unit has an operating element which is designed to be operable without tools, in particular in addition to a key for operating the lock. This advantageously allows a particularly simple assembly, a particularly simple removal or a particularly simple replacement of the battery. In particular, the clamping unit can be operated purely by hand via the operating element. This advantageously allows a particularly high degree of user-friendliness. An "operating element" is to be understood in particular as an element which has an operating surface for adjusting the operating state of the clamping unit, in particular the clamped operating state and the loosened operating state, by an operator. In particular, the operating element is designed as a lever, for example as a rocker, as a drawbar or as a torsion bar or as a knob, for example a key or a pushbutton. In particular, in the case of an operating element designed as a rocker, simple ergonomics can be advantageously achieved, in particular because in this case the actuation direction of the rocker overlaps with the insertion direction of the battery into the holding device predetermined by the support element. In particular, it is conceivable that the clamping unit has a bending lever, wherein preferably the operating element forms at least a part of the bending lever, in particular a leg. By using a bending lever, high clamping forces can be advantageously achieved during the clamping process when the operator performs manual actuation using a substantially constant tensioning force. In particular, the actuation force for actuating the operating element is at least substantially constant or linear, while the pressure generated by the clamping element of the bending lever, in particular the other leg of the bending lever, increases or decreases exponentially. In addition, it can be advantageously achieved by the bending lever that the operating element is supported at least substantially free of force in the clamped state, because the pressure acts in particular on the other leg of the bending lever.Thus, a long service life of the clamping unit can be advantageously achieved. Alternatively or in addition to the bending lever, the clamping unit can have a rotary locking pin, a screw closure, a bayonet joint or the like as a clamping mechanism. In particular, the operating element simultaneously forms a handle element, which is at least arranged to facilitate the removal of the battery. In particular, the handle element is configured as a tension pressure plate. The tension pressure plate can be advantageously grasped by the operator's hand and can be used to pull the battery out of the holding device. Particularly preferably, the clamping unit has a clamping element, which is arranged to support at least a large part of the pressure that occurs on the support element or the frame in the clamping operating state. Thus, a reliable retention of the battery can be advantageously achieved. In particular, when the distance between the point of action of the clamping force on the battery and the point of action of the clamping force on the support element perpendicular to the intermediate force direction is small, a higher force can be received by the clamping unit. In particular, the clamping element forms at least a part of the bending lever, in particular a leg, which is preferably different from the operating element. In particular, the clamping element is connected to the operating element by a hinge. Alternatively, however, it is also conceivable that the clamping unit has only a simple rocker without a bent lever geometry. In this case, the operating element can also be designed in one piece with the clamping element. In particular, the clamping element is provided to grip with a part of the support unit or with a part of the vehicle frame in order to generate pressure during the clamping process. It is conceivable that the locking unit is fastened to the support element by means of the clamping unit as described above, so that the battery which moves radially between the locking unit and the stop unit can be clamped between the locking unit and the stop unit, for example, by means of a latching element or clamping element arranged on the locking unit. It is also conceivable that the locking unit is screwed to the support unit.

[0013] It is further proposed that the support element has at least one side wall which is bent or folded relative to the main extension plane of the support element, which side wall at least partially covers the battery laterally at least when the battery is arranged on the support unit. It is conceivable that in order to achieve the task according to the invention, in an alternative configuration, the holding device is constructed independently of the change unit. Preferably, in an alternative configuration, in particular in a configuration constructed independently of the change unit, the holding device comprises at least a support unit, which has at least one support element, in particular a guide rail, for at least partially receiving and / or guiding the battery, wherein the support element has at least one side wall which is bent or folded relative to the main extension plane of the support element, which side wall at least partially covers the battery laterally at least when the battery is arranged on the support unit. As a result, at least partial guidance of the battery can be advantageously achieved. In particular, the battery is at least partially guided by the side wall during assembly. In particular, the battery is at least partially supported by the side wall in an operating state. It is conceivable that the side wall has a sliding element. Thus, damage to the battery and / or the support element, such as scratches, can be advantageously avoided to the greatest extent. It is also conceivable that the side wall has a plurality of sliding elements. For example, the sliding element can be constructed as a sliding roller or a sliding film. "Lateral coverage" should be understood in particular as meaning that an imaginary axis perpendicular to the outer wall of the battery intersects not only the side wall of the battery but also its outer wall, wherein the maximum extension dimension of the side wall is preferably smaller than the maximum extension dimension of the outer wall of the battery, in particular along a direction extending perpendicular to the longitudinal axis of the support element and parallel to the outer wall of the battery. Particularly preferably, the side wall is constructed integrally with the support element. Preferably, the side wall is arranged on the support element in such a way that the main extension direction of the side wall extends parallel to the longitudinal axis of the support element. It is conceivable that the maximum length of the side wall, in particular the maximum length along the main extension direction of the side wall, corresponds to the maximum length of the support element, in particular the maximum length along the longitudinal axis of the support element. The "main extension direction" of the structural unit should be understood in particular as a direction that extends parallel to the longest side of the smallest geometric cuboid that just still completely encloses the object. A "main extension plane" of a structural unit is to be understood in particular as a plane which is parallel to the largest side plane of the smallest possible imaginary cuboid which still completely encloses the structural unit and which in particular extends through the center of the cuboid. Preferably, the side walls of the support element enclose an angle of less than 180°, preferably less than 120° and very preferably more than 90° with the main extension plane of the support element. It is also conceivable that the side walls completely cover the battery in the lateral direction.

[0014] It is further proposed that the support element has at least one side wall bent or angled relative to the main extension plane of the support element and at least one further side wall bent or angled relative to the main extension plane of the support element, wherein the variable unit is arranged at least in the region between the side wall and the further side wall. This advantageously enables a two-sided guidance of the battery, in particular a two-sided guidance during assembly and / or removal. Preferably, the locking unit is guided at least partially by the side wall and / or the further side wall when arranged on the support element. In particular, in the operating state, the battery can be at least partially supported by the side wall and / or the further side wall. In particular, the side wall can protect the battery from damage. It is conceivable that the locking unit is at least partially supported by the side wall and the further side wall. This advantageously enables a high stability of the holding device. It is conceivable that the further side wall has a sliding element. This advantageously avoids damage to the battery and / or the support element, for example scratches. It is also conceivable that the further side wall has a plurality of sliding elements. In particular, the further side wall is constructed integrally with the support element. Preferably, the additional side wall is arranged on the support element in such a way that the main extension direction of the additional side wall extends parallel to the longitudinal axis of the support element. It is conceivable that the maximum length of the additional side wall, in particular the maximum length along the main extension direction of the additional side wall, corresponds to the maximum length of the support element, in particular the maximum length along the longitudinal axis of the support element. Preferably, the additional side wall of the support element encloses an angle of in particular less than 180°, preferably less than 120° and quite preferably more than 90° with the main extension plane of the support element. The side wall and the additional side wall are in particular arranged in such a way that the main extension directions of the side wall and the additional side wall are parallel to each other. It is conceivable that the side wall and the additional side wall have the same size. It is also conceivable that the side wall and the additional side wall have different sizes. It is conceivable that the angles, in particular multiple values ​​of the angle, in particular a certain value of the angle, bent at least relative to the main extension plane of the support element of the side wall and the additional side wall are the same. It is also conceivable that the angles, in particular the values ​​of the angle, bent at least relative to the main extension plane of the support element of the side wall and the additional side wall are different. It is also conceivable that the further side wall completely covers the battery in the laterally direction.

[0015] Furthermore, it is proposed that the support element has at least one side wall, in particular the previously mentioned side wall which is bent or angled relative to the main extension plane of the support element, in particular the previously mentioned side wall, and at least one further side wall, in particular the previously mentioned further side wall which is bent or angled relative to the main extension plane of the support element, wherein the variable unit is at least partially arranged on the side wall and / or on the further side wall. As a result, the holding strength of the holding device can be advantageously improved. It is conceivable that the side wall and / or the further side wall have a form-locking element. As a result, a high stability of the holding device can be advantageously achieved. Advantageously, the variability of the arrangement of the locking unit on the support element can be increased. It is conceivable that the side wall and / or the further side wall have a form-locking element or a plurality of form-locking elements of the variable unit. It is conceivable that the form-locking element of the side wall and / or the further side wall is provided for arranging the locking unit. In particular, the form-locking element of the side wall and / or the further side wall can establish a form lock with at least a part of the locking unit in an operating state. Preferably, the form-locking element of the side wall and / or the further side wall forms a form-locking groove, which is provided for receiving a part of the locking unit, in particular a form-locking mating element of the locking unit, in order to establish a form-locking connection. Preferably, the form-locking element is configured as a groove or depression in the side wall and / or the further side wall of the support element. Particularly preferably, the form-locking element of the side wall and / or the further side wall is configured as a polygonal, in particular rectangular groove. It is also conceivable that the form-locking element of the side wall and / or the further side wall is configured as an elongated hole, as a circular, oval or other groove or depression that seems meaningful to a person skilled in the art. It is also conceivable that the form-locking element of the side wall and / or the further side wall is configured as a groove with different shapes. It is conceivable that the variable unit has one or more sliding elements.

[0016] Furthermore, a frame, in particular a bicycle frame, is proposed, which has at least one holding device according to the invention. Preferably, the frame has at least one elongated element, and particularly advantageously, the frame is completely composed of elongated elements. In this case, "elongated element" is to be understood in particular as an element in which the smallest possible imaginary cuboid that can just accommodate the element has a length of at least five times, advantageously at least ten times and particularly advantageously at least fifteen times the width and height of the cuboid. In particular, the frame can have at least one recess for accommodating a holding device, in particular a support element and a battery. The recess can be configured, for example, as a depression or cavity of the frame. By arranging the holding device, in particular the support element, at least partially inside the cavity of the frame, the appearance of the frame in the state where the battery is arranged on the support element can be improved, and / or the wall thickness of the frame can be reduced, and / or foreign dirt and / or liquid can be prevented from entering the battery. In the case where the holding device and / or the support element are arranged inside the cavity, it is particularly advantageous in the configuration of the frame as a lightweight frame, for example a carbon fiber frame.

[0017] In addition, it is proposed that the frame comprises a tubular frame element, which is arranged to receive at least a large part of the holding device and at least a large part of the battery held by the holding device in its interior. As a result, a particularly space-saving loading of the battery can be advantageously achieved. In addition, the loading possibility for particularly long batteries and thus having a high energy storage capacity can be advantageously obtained. The "large part" of the component is particularly to be understood as at least 30%, preferably at least 50% and particularly preferably at least 70% of the total volume of the component. Preferably, the battery is pushed into the frame element along its longitudinal axis. In particular, the support element extends parallel to the frame element. In particular, during assembly, the battery is pushed in guided along the support element until the battery impacts on a stop unit fixed to the support element. However, it is also conceivable as an alternative to introduce the battery into the interior of the frame element through a lateral opening of the frame element. It is also conceivable to radially mount the battery on the support element when introducing the battery via the lateral opening of the frame element.

[0018] The holding device according to the invention and / or the frame according to the invention are not to be restricted to the applications and embodiments described above. In particular, in order to implement the functional principle described here, the holding device according to the invention and / or the frame according to the invention can have a number of individual elements, components and units that differs from the number mentioned here. Furthermore, with regard to the numerical ranges specified in the disclosure, values ​​within the mentioned limits are also to be regarded as disclosed and as being freely usable.

The stop unit 18a is fixedly connected to the support unit 14a, in particular to the support element 16a, in at least one fixed state, in particular by means of a displacement unit 104a. Preferably, the stop unit 18a can be arranged at different positions on the support element 16a, in particular by means of form-fitting elements 32a, 34a, by means of a displacement unit 104a arranged on the support element 16a. The stop unit 18a has a spring device 38a. The stop unit 18a has a stop member 76a. The spring device 38a is provided for prestressing the stop member 76a. The spring device 38a is provided for contributing to a clamping force for holding the battery 10a. The spring device 38a presses the stop member 76a in a direction parallel to the longitudinal axis 24a and pointing to a receiving area 78a of the support element 16a. The stop unit 18a has a plug element 44a. The plug element 44a is used for making electrical contacts of the battery 10a introduced into the receiving area 78a. The plug element 44a is arranged on the side 42a of the stop unit 18a facing the receiving area 78a. In the clamping operating state 22a, the plug element 44a is arranged on the side 42a of the clamping unit 20a facing the locking unit 106a. The stop unit 18a has a matching element 80a. The matching element 80a is configured to be embedded in a corresponding groove (not shown) of the battery 10a. As a result, an advantageous retention of the battery 10a can be achieved and / or an unsuitable battery 10a can be prevented from being pressed into the receiving area 78a to the greatest extent and from being damaged by the plug element 44a.

[0037] Figure 4 A schematic representation of a holding device 48a is shown, which has a locking unit 106a arranged on a support unit 14a for radially mounting a battery 10a on the holding device 48a. Preferably, the locking unit 106a is arranged at a position of the support element 16a. In particular, the locking unit 106a is arranged at a position on the support element 16a by means of a displacement unit 104a. Preferably, the locking unit 106a has form-fitting elements corresponding to the form-fitting elements 32a, 34a, which can be inserted into the form-fitting elements 32a, 34a for fixing. It is conceivable that a clamping unit 20a similar to the clamping unit 20b of the locking unit 106b is used to fix the locking unit 106a on the support unit 16a. After the locking unit 106a has been arranged on the support element 16a, the battery 10a can be pushed on radially and fixed on the support element 16a by the locking unit 106a. In particular, the rechargeable battery 10a is fixed to the carrier element 16a by means of latching elements, retaining elements or other fastening elements which are obvious to a person skilled in the art and which are arranged on the locking unit 106a.

[0038] Figure 5 A side view of a holding device 48a with an alternative battery 10a' is shown. The alternative battery 10a' is shorter than the previously shown battery 10a. Viewed along the longitudinal axis 24a, the alternative battery 10a' is shorter than the receiving area 78a. In addition, Figure 5 An alternative clamping unit 20a' is shown. The alternative clamping unit 20a' is fixedly connected to the support element 16a. The alternative clamping unit 20a' is configured to be separate from the alternative battery 10a'. The holding device 48a has an adapter element 58a. The adapter element 58a is configured to fill the gap 102a that occurs between the stop unit 18a and the alternative battery 10a'. The adapter element 58a has a longitudinal extension that is comparable to the longitudinal extension of the gap 102a. The adapter element 58a has at least one plug element 94a, 96a on two opposite sides. The first plug element 94a of the adapter element 58a is configured to be connected to the plug element 44a of the stop unit 18a. The second plug element 96a of the adapter element 58a is configured to be connected to the plug element 98a of the alternative battery 10a'. The plug elements 94a, 96a of the adapter element 58a are connected to each other via an electrical conductor 100a. The adapter element 58a is plated through.

[0039] exist Figures 6 to 10 A further embodiment of the invention is shown in FIG. The following description and drawings are essentially limited to the differences between the embodiments, wherein for identically labeled components, in particular for components with the same reference numerals, reference can essentially also be made to the drawings and / or to other embodiments, in particular Figures 1 to 5 In order to distinguish these embodiments, the letter a is placed in Figures 1 to 5 The reference numerals of the embodiments are shown in the figure. Figures 6 to 10 In the embodiment, the letter a is replaced by the letter b.

[0040] Figure 6 A schematic representation of a holding device 48b is shown, which has a locking unit 106b arranged on a battery 10b for axially mounting the battery 10b on the holding device 48b. The battery 10b has a clamping unit 20b, which is provided for arranging the locking unit 106b on a displacement unit 104b, which is arranged on a support element 16b of a support unit 14b. During axial mounting, the battery 10b is pushed onto the support element 16b along a longitudinal axis 24b and is guided at least partially by the side walls 110b, 112b until the battery 10b strikes the stop unit 18b. In this position, the clamping unit 20b can be brought from a relaxed state into a clamping operating state 22b for fixing the battery 10b on the support element 16b.

[0041] Figure 7a Another part of the holding device 48b is shown with a battery 10b and a locking unit 106b in a clamping operating state 22b. The locking unit 106b has a clamping unit 20b. The clamping unit 20b is provided for fixing the battery 10b on the bracket unit 14b in the clamping operating state 22b. The clamping unit 20b is provided for clamping the battery 10b between the clamping unit 20b and the stop unit 18b in the operating position in such a way that the clamping unit 20b applies a pressure to the battery 10b in the clamping operating state 22b, which pressure acts in the direction of the stop unit 18b. The pressure applied by the clamping unit 20b to the battery 10b in the clamping operating state 22b acts parallel to the longitudinal axis 24b of the bracket element 16. Figure 6 The spring device 38b shown in the clamping operating state 22b generates a spring force that counteracts the clamping force of the clamping unit 20b. The clamping unit 20b is fixedly connected to the battery 10b. The clamping unit 20b is mounted on the battery 10b. The clamping unit 20b has a housing 54b. The housing 54b closes the clamping unit 20b outwardly at least on the side facing away from the battery 10b. The clamping unit 20b has an operating element 26b. The operating element 26b is configured as a rocker. The operating element 26b is configured to be operable without tools. The clamping unit 20b has a locking device 36b. The locking device 36b locks the operating element 26b in the clamping operating state 22b. The locking unit 36b has another operating element 66b. The other operating element 66b is configured as a button. The other operating element 66b is at least configured to release the lock of the locking device 36b when it is operated. In the closed state, that is, in the clamping operating state 22b, the operating element 26b is flush with the front side of the clamping unit 20b, in particular with the housing 54b of the clamping unit 20b. Unwanted manipulation (e.g. theft) can thus be advantageously excluded. In addition, a clear indication can thus be advantageously provided to the operator of the operating element 26b that the operating element 26b and thus the battery 10b are correctly fastened.

[0042] Figure 7b Show Figure 7a4. A vertical cross section of another part of the holding device 48b in the locking unit 106b. The clamping unit 20b of the locking unit 106b has a clamping element 28b. The clamping unit 20b has a bending lever 82b. The operating element 26b constitutes a leg of the bending lever 82b. The clamping element 28b constitutes another leg of the bending lever 82b. The swinging of the operating element 26b causes the swinging of the clamping element 28b. The clamping element 28b is configured to support at least a large part of the pressure occurring on the support element 16b in the clamping operating state 22b. Alternatively, the clamping element 28b can be configured to support the pressure directly acting on the frame 12b in the clamping operating state 22b. The clamping element 28b has a shape locking element 30b. The shape locking element 30b is constructed in a clamping manner. The clamping unit 20b is configured to maintain pressure in the clamping operating state 22b. The displacement unit 104b of the support element 16b has corresponding form-locking elements 32b, 34b. The corresponding form-locking elements 32b, 34b are provided for engaging with the clamping element 28b of the clamping unit 20b in order to establish the clamping operating state 22b. The corresponding form-locking elements 32b, 34b are constructed as grooves in the support element 16b. The clamp-like form-locking element 30b is embedded in the corresponding form-locking element 32b, 34b in the clamping operating state 22b and is thereby gripped with the corresponding form-locking element 32b, 34b. Due to the bending lever geometry of the bending lever 82b, when the operating element 26b is closed, the clamping unit 20b is pressed in the direction of the battery 10b. Similar to Figure 3 In the embodiment of the change unit 104a in the holding device 48b, the change unit 104b of the holding device 48b has a plurality of corresponding form-fitting elements 32b, 34b. Different corresponding form-fitting elements 32b, 34b are arranged at different distances from the stop unit 18b along the longitudinal axis 24b of the support element 16b. Different corresponding form-fitting elements 32b, 34b are used to enable the assembly of storage batteries 10b of different lengths.

[0043] Figure 8a and 8b A section of a holding device 48b with a locking unit 106b is shown in a relaxed operating state 84b. The operating element 26b is completely flipped outwards. Due to the bent lever geometry, the clamping element 28b is flipped out of the corresponding form-fitting elements 32b, 34b of the adjustment unit 104b of the support unit 14b. The operating element 26b and the clamping element 28b are not in contact with the support unit 14b. In the relaxed operating state 84b, the battery 10b with the locking unit 106b with the clamping unit 20b can be removed from the receiving area 78b along the longitudinal axis 24b of the support element 16b. In the relaxed operating state 84b, the operating element 26b constitutes a handle element, in particular a tension pressure plate. For reasons of clarity, in Figure 7a and 7b The locking device 36 is omitted.

[0044] Fig. 9 A horizontal section of a portion of a clamping unit 20b is shown with a locking unit 106 having a locking device 36b. Fig. 9 In the position shown in, in the clamping operating state 22b, the operating element 26b is locked by the locking device 36b. The locking device 36b has a locking element 60b. The locking element 60b is configured as a locking hook. The locking device 36b has a locking element 62b. The locking element 62b is inserted into the operating element 26b. The locking element 62b has another operating element 66b. The locking element 62b has a counterpart 86b. In the clamping operating state 22b locked by the locking device 36b, the counterpart 86b is abutted against the locking hook. The locking element 62b is locked with the locking hook by the counterpart 86b. The locking of the counterpart 86b of the locking element 62b with the locking hook prevents the movement of the operating element 26b connected to the locking element 62b at least in the swinging direction of the operating element 26b, especially in the direction parallel to the longitudinal axis 24b of the support element 16b. The locking device 36b has a spring element 88b. The spring element 88b supports the locking element 62b relative to the operating element 26b. The locking element 62b is supported on the operating element 26b by the spring element 88b in the direction of the actuation direction 90b of the locking element 62b, in particular the other operating element 66b. Due to the pressure acting on the other operating element 66b, the spring element 88b is compressed and the counterpart 86b is removed from the engagement with the latch element 60b. Therefore, the storage battery 10b is pressed out of the receiving area 78b by the spring device 38b of the stop unit 18b. As a result, the operating element 26b is slightly swung, so that the locking element 62b can no longer be locked with the latch element 60b again. As a result, the storage battery 10b is released and can be taken out from the receiving area 78b along the longitudinal axis 24b. The locking element 62b has a positioning element 92b. The positioning element 92b is arranged to prevent the locking element 62b from being released from the operating element 26b. Furthermore, the positioning element 92b is provided to limit a maximum extension of the spring element 88b.

[0045] Fig.10 An exploded view of a portion of the clamping unit 20b is shown. Figures 6 to 9 In comparison, Fig.10 The individual components of the clamping unit 20b shown in FIG. 1 have slightly different shapes, but the functions are substantially the same. Components with the same designations or reference numerals in the following description and drawings correspond to the previously mentioned components and have their functions. Figures 6 to 9 In addition to the configuration, Fig.10The holding device 48b in the embodiment has a lock 40b. The lock 40b is provided for locking and / or unlocking the clamping unit 20b. The lock 40b is integrated into a housing 54b of the clamping unit 20b.
