[0004] Energy storage assembly for a two-wheeler with two swiveling locking elements for holding an energy storage unit on a holder of the two-wheeler.

[0005] Description

[0006] The proposed solution concerns an energy storage assembly for a two-wheeler, in particular an electric bicycle and thus a so-called e-bike or pedelec.

[0007] Particularly in connection with electric bicycles, it is widely known to provide a holder on the frame of the electric bicycle for holding an energy storage unit, to which the energy storage unit can be detachably attached and locked. A locking device with at least one locking element adjustable to a locking position is provided to lock the energy storage unit held on the holder to the holder. Typically, the locking device is equipped with a lock so that a user can adjust the locking element to its locking position by turning a key for the lock. Furthermore, it is known to additionally provide a locking device that mechanically secures the energy storage unit to the holder independently of the at least one locking element.The locking device can thus hold the energy storage unit on the holder even after the locking device has been actuated to release the lock. Conversely, the locking device can already hold the energy storage unit on the holder before a lock has been engaged using the at least one [function / function].

[0008] 2024461 P BRG196 Page 2

[0009] The locking element ensures that the energy storage unit does not fall off the frame of an e-bike due to gravity when only the locking mechanism is activated, and conversely, it is already held in place by the locking device on the frame before a user activates the locking mechanism.

[0010] For example, DE 20 2016 104 156 U1 discloses an energy storage assembly for an electric bicycle in which a locking device has a spring-loaded locking bolt. When a lock is actuated, this bolt only allows the energy storage unit to pivot to an intermediate position, thus preventing it from being fully folded out. The user must then adjust the locking bolt separately to detach the energy storage unit from the holder and thus from the frame of the electric bicycle. Consequently, a user must first actuate the locking device and then the locking mechanism to remove the energy storage unit.

[0011] Regardless of the method used to mount an energy storage unit to a bicycle bracket, a key consideration for any energy storage assembly is that it is securely and rattle-free attached to the bracket. This is especially important for sporty bicycle models, particularly mountain bikes. The energy storage unit should not detach from the bracket or rattle, even under significant vibrations. Even when subjected to hard impacts from the bicycle frame and strong acceleration forces, the energy storage unit should remain reliably locked in its operating position on the bracket.

[0012] In light of the aforementioned requirements, there is therefore still a need for improved energy storage modules for two-wheelers, especially electric bicycles.

[0013] An energy storage assembly for a two-wheeled vehicle is now proposed, comprising an energy storage unit with at least one energy storage device for providing energy to power the two-wheeled vehicle. For example, the energy storage unit includes at least one battery, in particular a rechargeable battery. Furthermore, a bracket is part of the energy storage assembly, designed to hold the energy storage unit on the two-wheeled vehicle. The energy storage unit can be detachably fixed to the bracket, allowing the energy storage unit to be easily removed by the user.

[0014] 2024 461 P BRG196 Page 3 of the two-wheeler can be separated from the holder and thus from the two-wheeler without tools once the energy storage assembly has been mounted on the two-wheeler. The proposed energy storage assembly further comprises a locking device with at least one locking element adjustable into a locking position, wherein the locking device is designed to lock the energy storage unit held on the holder to the holder. Consequently, the locking device allows the energy storage unit, held on the holder in a working position, to be locked to the holder against accidental, improper, or unauthorized removal from the holder.

[0015] A proposed energy storage assembly further comprises a locking device for mechanically securing the energy storage unit to the holder independently of the at least one locking element, wherein the locking device comprises a first locking element and a second locking element. The first locking element is pivotable about a first pivot axis, while the second locking element is pivotable about a second pivot axis. The first and second pivot axes can, in particular, be parallel or coaxial to each other. The first and second locking elements are each pivotable from a locking position to a release position, wherein the first and second locking elements are designed to hold the energy storage unit to the holder in their locking positions and only release the energy storage unit from the holder for separation when pivoted into the release positions.Only when both locking elements, the first and second, are pivoted into the release positions can the energy storage unit be removed from the holder.

[0016] By incorporating two pivoting locking elements into the locking device, significant advantages can be achieved compared to solutions known from the prior art. Not only can the mechanical locking and thus securing of the energy storage unit to the holder be made redundant and therefore more secure, but two locking elements also offer further advantages that improve user convenience when locking and releasing the energy storage unit to the holder. This is particularly relevant when the energy storage unit is detached from the holder and needs to be (re)attached, and the locking mechanism should engage automatically before the user operates the locking device. Furthermore, it is easier to integrate a [missing information - likely a specific component or feature] into the locking device.

[0017] 2024 461 P BRG196 Page 4

[0018] Play-free mechanism for the play-free mounting of the energy storage unit on the holder can be integrated.

[0019] In particular, it can be provided that the first and second locking elements are each pivotable from the locked position to an intermediate position and from the intermediate position to the release position, and that the first and second locking elements are designed to jointly hold the energy storage unit on the holder in their intermediate positions even when the at least one locking element is moved from the locked position to an unlocked position. The locking elements then only release the energy storage unit from the holder after pivoting from their intermediate positions to the release positions. In this embodiment, the energy storage unit therefore remains held on the holder by the first and second locking elements, which are pivoted into their intermediate positions, even after the locking mechanism has been released via the at least one locking element.The energy storage unit therefore does not fall out of its operating position on the bicycle due to gravity as soon as a locking mechanism is released. Releasing the lock merely allows the first and second locking elements to be moved from their locked positions to intermediate positions. In these intermediate positions, the energy storage unit remains held in place on the holder. From these intermediate positions, the locking elements can be moved further into their release positions, thus allowing the energy storage unit to be removed from the holder.

[0020] In principle, it is possible that releasing the locking mechanism via at least one locking element allows the energy storage unit to shift from its operating position to an intermediate position relative to the holder, possibly due to gravity, thereby moving the first and second locking elements from their locked positions to these intermediate positions. However, this is not mandatory. For example, moving at least one locking element into its unlocked position can also exert a force on the first and second locking elements to move them from their locked positions to these intermediate positions.Alternatively, to remove the energy storage unit, the locking elements can be moved from their locked positions to the released positions by a user-applied adjusting force after the energy storage unit has been released via the locking device. For this purpose, at least one handle section can be provided for external user access.

[0021] 2024 461 P BRG196 Page 5 the adjusting force can be applied to pivot one or both locking elements into the respective release position when the locking has been released via the locking device.

[0022] It is also not necessarily the case that pivoting the first and second locking elements into their intermediate positions results in a shift of the energy storage unit from its operating position to an intermediate position. The energy storage unit can remain in its operating position when the locking elements are moved from their locked positions to their intermediate positions. The shift to the intermediate position may simply mean that the locking mechanism of the energy storage unit on the holder is at least partially released, and the energy storage unit may no longer be held securely on the holder, but rather with some play.

[0023] In one embodiment, the first and second locking elements are pivotable from their locked positions to their released positions along opposing directions. Two first and second locking elements that pivot in opposite directions can prove advantageous, for example, for eliminating play when securing the energy storage unit to the holder. Furthermore, two first and second locking elements that pivot in opposite directions can facilitate manual adjustment of both locking elements by a single user. For instance, users would only need to press two accessible sections of the locking elements towards each other to pivot both locking elements in opposite directions toward their released positions.

[0024] In one embodiment, at least one of the locking elements is pivotally mounted on the energy storage unit. This includes, in particular, an embodiment in which both the first and second locking elements are pivotally mounted on the energy storage unit. In such a case, the first and second locking elements are therefore located on the energy storage unit. By locating the locking elements on the energy storage unit, which can be removed from the holder, they can be more easily maintained and, if necessary, replaced than would be the case if they were integrated into the holder, which is fixed to the two-wheeler.

[0025] 2024 461 P BRG196 Page 6

[0026] For example, the locking elements can be pivotally mounted on a first end face of a longitudinally extended energy storage unit. This first end face of the energy storage unit is intended for the detachable, mechanical fastening of the energy storage unit to the holder. A second end face of the energy storage unit, on the other hand, serves, for example, to attach the energy storage unit to the holder and support it against the holder (e.g., at a connecting part of the holder) when the first end face is pivoted into its operating position around a pivot axis defined in the area of ​​the second end face, as is the case, for example, with previously known battery solutions for e-bikes that are attached to a down tube or seat tube of the e-bike.

[0027] If the first and second locking elements are pivotably mounted on the energy storage unit, the holder may be provided with a first counterpart for interaction with the first locking element and a second counterpart for interaction with the second locking element. The respective first or second locking element engages with its corresponding first or second counterpart in the locking position, in particular in a positive-locking and / or frictional engagement. If the first and second locking elements are each pivotable into an intermediate position, it may also be provided that a positive-locking and / or frictional engagement exists between a locking element and its corresponding counterpart on the holder in the respective intermediate position.

[0028] A first and / or second counterpart can project axially from the holder, relative to the respective first or second pivot axis of the associated locking element, in the direction of the energy storage unit, when the energy storage unit is fixed to the holder and the locking elements are in their locked positions. For example, a counterpart can be pin-shaped or conical. The projecting counterpart is provided, for example, on a locking part of the holder and projects axially from this part, relative to a direction of extension of the holder from the locking part to a connecting part opposite the locking part, with the energy storage unit being arranged on the holder between the locking part and the connecting part.

[0029] As an alternative to the above-described design variants, which provide at least one locking element pivotably mounted on the energy storage unit, it is of course also possible that one of the first and second

[0030] 2024 461 P BRG196 Page 7

[0031] Locking elements, or both locking elements, are pivotally mounted on the bracket, which is fixed to the frame when the energy storage assembly is properly installed on the bicycle. In this case, a counterpart of the energy storage unit would engage with a locking element on the bracket to secure the energy storage unit to the bracket.

[0032] In principle, both the first and second locking elements can be pre-tensioned into their respective locking positions. Pre-tensioning into the locking position can primarily serve the purpose of automatically and conveniently locking the energy storage unit, which has been detached from and attached to the holder, to the holder when the energy storage unit is brought into a specific relative position to the holder.This includes, for example, an embodiment in which the first locking element and the second locking element are each pre-tensioned in their locking position and arranged on the energy storage unit in such a way that, when the energy storage unit, which is (still) separate from the holder, is attached to the holder along an attachment direction, the first and second locking elements are initially moved out of their locking position by contact with the first and second counterparts of the holder, and, under the influence of the pre-tension of the first and second locking elements, the locking elements are moved back towards their locking positions to their intermediate positions as the energy storage unit (and thus the part of the energy storage unit carrying the first and second locking elements) is further moved along the attachment direction.In the intermediate positions, the first and second locking elements engage with their corresponding counterparts, whereby by assuming the intermediate positions the energy storage unit is held on the holder and mechanically secured against unintentional removal from the holder.

[0033] To displace the first and second locking elements against the preload force applied to them (e.g., by at least one spring element), the first and / or second locking element can have an insertion ramp. When the energy storage unit is attached to the holder, the corresponding first or second counterpart of the holder slides along this ramp, displacing the section of the first or second locking element that forms the insertion ramp. This displacement causes the respective locking element to pivot against the preload about its (first or second) pivot axis. The insertion ramp is configured and dimensioned such that attaching the energy storage unit to the holder causes the respective pivoting element to pivot.

[0034] 2024 461 P BRG196 Page 8 until it is forced beyond the respective intermediate position. Once a section of an energy storage-side locking element having the insertion ramp has passed a counterpart on the holder side, the locking element, pre-tensioned in the direction of its locking position, can snap back into the intermediate position and thereby engage with the counterpart.

[0035] In a possible further development, it is proposed that the first and second locking elements must be manually adjusted from intermediate positions to their locked positions before the at least one locking element can be moved into its locked position. Consequently, the first and second locking elements must first be deliberately applied by a user with an adjustment force to move them into their locked positions. Only then is locking via the at least one locking element possible. This ensures that, before locking via the at least one locking element, the energy storage unit's operating position is already mechanically secured as intended by the first and second locking elements. Locking via the at least one locking element is thus blocked beforehand.

[0036] To adjust a locking element from an intermediate position to the locked position, a user-accessible handle section can be provided, at which the necessary adjustment force must be applied manually. Such a handle section can, for example, be radially further away from the respective first or second pivot axis than a locking section of a locking element, via which a positive-locking and / or friction-locking engagement with a counterpart occurs in the locked position. The resulting leverage effect allows a user to adjust a locking element to its locked position with comparatively little manual effort.

[0037] In one design variant, the first and second locking elements can be configured to axially clamp the energy storage unit to the holder relative to a clamping axis running parallel to the first and second pivot axes when adjusted to their locking positions. This eliminates play along the clamping axis. The aim is to secure the energy storage unit to the holder, and thus to the bicycle, without any play using the pivotable first and second locking elements. The axial clamping force applied by the first and second locking elements can compensate for tolerances and any size differences in the available components.

[0038] 2024 461 P BRG196 Page 9 standing receiving space for an energy storage unit on the holder and / or any size differences between different energy storage units. By applying an axial clamping force and thereby eliminating play, it can also be ensured that the energy storage unit is held rattle-free on the holder, even when strong acceleration forces act on the two-wheeler.

[0039] To generate the axial clamping force, at least one clamping ramp can be provided on the first locking element and / or on the second locking element. When the respective locking element is adjusted, this ramp engages a bearing surface, and the axial clamping force is applied via this bearing surface in conjunction with the at least one clamping ramp. One or more bearing surfaces can be provided on the energy storage unit and / or the holder. The clamping ramp preferably runs inclined to the pivoting direction of the respective locking element, so that the axially acting clamping force can be generated by the pivoting movement of the first or second locking element into its locking position, with the clamping ramp sliding along the bearing surface.

[0040] Alternatively or additionally, a variant embodiment provides that the first locking element has a first body with a first locking opening for the at least one locking element, and the second locking element has a second body with a second locking opening for the at least one locking element. In its locking position, the at least one locking element must then engage at least in one of the first and second locking openings, or, in a further development, in both the first and second locking openings, in order to lock the energy storage unit to the holder.By making such engagement in at least one or both locking openings of the first and second locking elements possible only in a specific relative position of the first and second locking elements to each other and to the holder, it can be ensured, for example, that locking via the at least one locking element can only occur when the first and second locking elements are in their locked positions. For example, the first and second bodies are arranged to overlap each other at least partially. The first and second locking openings then only partially overlap each other in the locked positions of the first and second locking elements, such that the at least one locking element can engage both the first and second locking openings. Only when the first and second locking elements are moved into their locked positions is there thus no locking between the first and second locking elements.

[0041] 2024 461 P BRG196 Page 10 Sufficient overlap is provided between the second locking openings so that the at least one locking element can be moved from an unlocked position to the locked position in which the at least one locking element engages in both locking openings. In the locked position of the at least one locking element, the first and second locking elements are thus each blocked against movement from their locked positions. In other words, neither of the locking elements can be moved from its locked position as long as the at least one locking element is in its locked position when the energy storage unit is held on the holder.The at least one locking element thus secures the first and second locking elements in the locked positions and thereby secures the mechanical locking of the energy storage unit on the holder, which is provided via the first and second locking elements.

[0042] One design variant, intended to facilitate the removal of the energy storage unit from the holder, provides a user-accessible grip section for both the first and second locking elements in the release position (or, if necessary, an intermediate position). This grip section allows the user to apply force to detach the energy storage unit from the holder. Thus, the user can manually grasp the grip sections for the first and second locking elements to permanently separate the energy storage unit from the holder. These grip sections can be designed for one-handed operation, enabling the user to grasp the grip sections for the first and second locking elements with one hand and apply the necessary force to detach the energy storage unit.

[0043] In particular, these grip sections can also allow a user to apply the adjusting force to the first and second locking elements, enabling them to pivot from intermediate positions to release positions. Especially if the first and second locking elements are not intended to assume an intermediate position for removing the energy storage unit from the holder, a grip section accessible to a user in the locked position can also be provided on the energy storage unit. This grip section allows the user to apply an adjusting force to the respective first or second locking element to pivot it from the locked position to the release position. The grip sections for the first and second locking elements can thus be designed and attached to the energy storage unit in this manner.

[0044] 2024 461 P BRG196 Page 11 arranged so that a user can grasp both handle sections with one hand and push the handle sections towards each other - in the case of opposing pivoting locking elements - in order to pivot the locking elements together into the release positions.

[0045] In a further training session, the storage unit can then be separated from the holder by pulling on the compressed handle sections of the energy storage unit. This makes separating the energy storage unit from the holder particularly intuitive for the user. At the same time, a high level of safety is achieved by specifying a particular procedure for removing the energy storage unit.

[0046] The proposed solution further relates to an electric bicycle with an embodiment of a proposed energy storage assembly, in which the energy storage is set up and provided for the supply of electrical energy to power the electric bicycle and for this purpose comprises at least one energy storage device with a - preferably rechargeable - battery.

[0074] Lower tube of figure 12.

[0075] Figure 13 illustrates an electric bicycle 1 with an electric motor drive unit A. The electric bicycle 1 has a frame 10, which here by way of example comprises a top tube 10.1, a down tube 10.2 and a seat tube 10.3, and on which, in the area of ​​a point where the seat tube 10.3 and the down tube 10.2 intersect, the

[0076] 2024 461 P BRG196 Page 14

[0077] The drive unit A is attached. Part of the drive unit A is a control electronics unit SE and a sensor device 15, for example, equipped with a torque sensor and a position sensor, for the sensory detection of a torque applied to a drive shaft in the form of a bottom bracket shaft AT of the drive unit A by muscle power. The sensor device 15 can alternatively or additionally include a speed sensor, via which the rotational speed of the bottom bracket shaft AT can be detected.

[0078] A drive element of the drive unit A, for example a hollow output shaft mounted coaxially to the bottom bracket axle AT, is connected to a rear wheel 12 of the electric bicycle 1 via a belt or chain 13 as a power transmission link, in order to drive the electric bicycle 1. This rear wheel 12 is equipped, for example, with a wheel sensor 14 for determining the speed of the electric bicycle. Of course, the wheel sensor 14 could instead be located on a front wheel 11 of the electric bicycle 1.

[0079] The drive unit A is part of a drive system of the electric bicycle 1, which further comprises a control unit 2. In Figure 13, for example, the control unit 2 is attached in the area of ​​the handlebars of the electric bicycle 1 and connected to the control electronics SE of the drive unit A, typically via one or more cables 41.1 41.2. User input can be detected via the control unit 2 and used to control the drive unit A. For example, the control unit 2 further comprises at least one display to inform a user of the electric bicycle 1 about

[0080] - the current operating status of drive unit A, for example with regard to a set support level,

[0081] - a state of charge of a battery unit 3 that supplies the drive unit A with electrical energy and contains at least one (rechargeable) battery, and / or

[0082] - to inform a set gear which specifies the translation with which a drive torque initiated by muscle power at the bottom bracket shaft AT is transmitted to the output element of the drive unit A.

[0083] Cables 41.1 and 41.2 are schematically shown in Figure 13 for connecting the battery unit 3 to the control unit 2 and for signal transmission between the control unit 2 and the control unit SE of the drive unit A. Cables 41.1 and 41.2 connect the control unit 2 to a connection part 43 of a holder in the form of a battery holder 4, which is provided on the down tube 10.2 for holding the battery unit 3.

[0084] 2024 461 P BRG196 Page 15

[0085] The downtube 10.2 with the battery holder 4 is shown in section in Figure 12. The battery holder 4 is mounted here in a battery compartment 1020 of the downtube 10.2. The battery unit 3 is to be received in the battery compartment 1020, which is open at the bottom. Within the battery compartment 1020, the battery holder 4 defines a receiving space for the elongated and, in this case, cuboid-shaped battery unit 3 between the connecting part 43 and a locking part 41. The locking part 41 and the connecting part 43 are connected to each other via a central part 42 of the battery holder 4.

[0086] A connector 430 is provided on the connection part 43 to connect the cables 41.1 and 41.2 to the battery unit 3 when the battery unit 3 is mounted on the battery holder 4 as intended. The locking part 41 of the battery holder 4 ensures that the battery unit 3 remains mechanically secured to the battery holder 4, and thus to the down tube 10.2 of the electric bicycle 1, in a predetermined operating position and, in particular, cannot be improperly removed from the sub-tube 10.2.

[0087] To attach the battery unit 3 to the battery holder 4, the battery unit 3 is positioned with a second end face 3B against the connection part 43, in this case along a first mounting direction AR1. Subsequently, the battery unit 3 is pivoted into the battery compartment 1020 about a pivot axis defined in the area of ​​the connection part 43 along a second mounting direction AR2. This brings a first end face 3A of the battery unit 3 into contact with the locking part 41, which mechanically locks the pivoted battery unit 3 into place. A locking device 5 with a lock cylinder is part of the locking part 41, specifically for this purpose. The battery unit 3, which is attached to the down tube 10.2 as specified, can be locked to the battery holder 4 using a key 6 via the locking device 5. Without the key 6, the battery unit 3 can no longer be removed from the subfolder 10.2.2 will be removed.

[0088] In one embodiment of the proposed solution, a locking device is provided in addition to the locking device 5 to mechanically secure and lock the battery unit 3 to the battery holder 4 independently of the locking device 5, so that, on the one hand, the battery unit 3 does not remain on the battery holder 4 only when the locking device 5 is actuated by turning the key 6, and on the other hand, the battery unit 3 does not fall out of the battery compartment 1020 of the down tube 10.2 due to gravity as soon as the locking device 5 is released.

[0090] Figures 1A to 11 show further details of the locking device 5 and its interaction with an additional locking device provided, which in the illustrated embodiment comprises two locking elements in the form of locking levers 71, 72 pivotably mounted on the first end face 3A.

[0091] Figures 1A and 1B show the first end face 3A of the battery unit 3 with the locking levers 71 and 72 pivotably mounted thereon about parallel pivot axes S1 and S2 in a locked position. A first locking lever 71 is pivotally mounted about a first pivot axis S1 on the first end face 3A and has a locking section in the form of a locking hook 711. In the depicted locked position, the locking hook 711 closes a retaining element opening in the form of a pin opening 341A on the first end face 3A. Looking at the rectangular first end face 3A, the locking hook 711 is located in the region of an upper right corner of the first end face 3A. Diagonally spaced from this, i.e., in the region of a lower left corner of the first end face 3A, the locking lever 71 has a grip section 712. A user can manually grasp the handle section 712 to pivot the first locking lever 71 into a release position around the first pivot axis S1.This will be explained in more detail below.

[0092] As further illustrated in Figure 4, the first pivot axis S1 is defined by a pivot bearing pin projecting from the first end face 3A. The first locking lever 71 is pivotally mounted on this pivot bearing pin via a pivot bearing section 71 OS of a body 710 of the first locking lever 71. The pivot bearing section 71 OS has a through-opening into which the pivot bearing pin of the first end face 3A engages in a form-fitting manner. The radial distance of the handle section 712 to the first pivot axis S1 is, in this case, many times greater than the radial distance of the locking hook 711 to the pivot axis S1, so that, given the resulting leverage, a user can apply a comparatively large adjusting force to the locking hook 711 via the handle section 712.

[0093] The second locking lever 72 is designed identically to the first locking lever 71, in particular essentially as a mirror image. The second locking lever 72 thus has a body 720 with a pivot bearing section 720S for defining the second pivot axis S2. A (further) pivot bearing pin projecting from the first end face 3A also engages positively in an opening of the pivot bearing section 720S.

[0094] 2024 461 P BRG196 page 17. Furthermore, the second locking lever 72 also forms a locking section in the form of a locking hook 721, which, in its locked position, closes a pin opening 342A in the area of ​​the upper left corner of the first end face 3A. Diagonally opposite the (second) locking hook 721, a (second) handle section 722 of the second locking lever 72 is formed on its body 720.

[0095] Figures 1A and 1B each show a cover 8 attached to the first end face 3A of the battery unit 3, which at least partially covers the locking levers 71, 72 for protection. However, the cover 8 does not cover the handle sections 712, 722 and the locking hooks 711, 721. Furthermore, the cover 8 has two adjacent through-openings 87.1 and 87.2 which, in the locking positions of the locking levers 71, 72, are aligned with locking openings 7100, 7200 and 7101, 7201 respectively of the two locking levers 71, 72, so that a locking bolt 56 of the locking device 5 can be guided through a through-opening 87.1 or 87.2 and a pair of successive locking openings 7200 / 7100 or 72001 / 7101 behind it (see also Figures 3 and 11).

[0096] Figure 1B shows the battery unit 3 with a bearing element of the locking part 41 in the form of a bearing block 410. Two axially projecting counterparts or retaining elements in the form of locking pins 411 and 412 are formed on the bearing block 410. In the respective locking position, a locking pin 41 or 412 engages an associated locking hook 711 or 721 of a locking lever 71 or 72. A locking lever 71 or 72 thereby positively locks the battery unit 3 to the locking part 41 and, if necessary, also frictionally locks it when the locking levers 71 and 72 are in their respective locking positions. A locking pin 411 or 412 then engages in the pin opening 341 A or 342A on the first end face 3A and is secured in the pin opening 341 , 342A by the respective associated locking lever 71 , 72 which is in its locking position.Without adjusting the locking levers 71, 72 about their pivot axis S1, S2 into a release position shown in Figures 2A and 2B, the battery unit 3 cannot be separated from the locking part 41 and thus removed from the battery compartment 1020.

[0097] In the release positions of the locking levers 71, 72 shown in Figures 2A and 2B, the locking hooks 711 and 721 release the respective pin openings 341A, 342A. For this purpose, the two locking levers 71, 72 are pivoted in two opposing directions about their pivot axes S1, S2. A user can operate this mechanism by gripping the handle sections 412 and 422 projecting from the battery unit 3 with one hand.

[0098] 2024 461 P BRG196 Page 18. By pressing the handle sections 712 and 722 together, the locking levers 71, 72 on the first end face 3A are pivoted in opposite directions to each other, i.e., the first locking lever 71 counterclockwise around the first pivot axis S1 and the second locking lever 72 clockwise around the second pivot axis S2. When the handle sections 712 and 722 with contact surfaces 7120, 7220 are in contact with each other, the locking levers 71, 72 are pivoted maximally into their release positions. This completely releases the mechanical locking of the battery unit 3 on the locking part 41 or its locking pins 411, 422.

[0099] Before the locking levers 71, 72 can pivot into their release positions, a lock must first be released via the locking device 5. As shown in Figure 3, the locking device 5 has a lock cylinder for the key 6 on the locking part 41. Using the key 6, the lock pin 56 can be moved from the locked position shown in Figure 3 to an unlocked position on the locking part 41. When the lock pin 56 is in the axially projecting locking position shown in Figure 3, with the battery unit 3 inserted into the battery holder 4 as specified and the locking levers 71, 72 in their locked positions, the lock pin 56 engages through the through-opening 87.2 of the cover 8 into the locking openings 7201, 7101 of the two locking levers 71, 72, which are arranged one behind the other.This secures the two locking levers 71, 72 in the locked positions and blocks them against movement towards their release positions by the locking pin 56.

[0100] As illustrated in particular by Figure 4, the bodies 710, 720 of the two locking levers 71, 72 overlap each other at least partially, so that in the locking positions of the two locking levers 71, 72 a pair of locking openings 7200, 7100 or 7201, 7101 overlap each other at least partially, and the locking bolt 56 can engage in both overlapping and thus successive locking openings 7200, 7100 or 7201, 7101.

[0101] The provision of two pairs of locking openings 7200 / 7100 and 7201 / 7101 on the bodies 710, 720 of the two locking levers 71, 72 allows the battery holder 3 to be combined with different locking devices 5. For example, if it is desired that the lock cylinder of the locking device 5 be accessible on the other longitudinal side of the lower tube 10.2, the lock pin 56 would not, as in the illustrated embodiment, be connected to one pair of locking openings in the

[0102] 2024 461 P BRG196 Page 19

[0103] The locking positions of the locking levers 71, 72 behind the through-opening 87.2 are brought into engagement with the locking openings 7201, 7101 accessible, but - through the other through-opening 87.1 of the cover 8 - with the other pair of locking openings 7200, 7100.

[0104] As illustrated in Figure 5A, the handle sections 712, 722, which pivot the locking levers 71, 72 into their release positions when brought close together, not only allow one-handed operation by a user to disconnect the battery unit 3 from the battery holder 4. Rather, a user can also pull both of the pressed-together handle sections 712, 722 along a removal direction E with one hand H to pivot the battery unit 3 out of the battery compartment 1020 of the down tube 10.2. The removal direction E thus points downwards in the intended installed state of the illustrated energy storage assembly.

[0105] As illustrated in Figure 5B, it may also be necessary to pull the battery unit 3 upwards out of a battery compartment. In this case, a user can simply use one hand H to pull the pressed-together grip sections 712, 722 along the removal direction E (then upwards) to remove the battery unit 3 from the battery holder 4. Of course, pulling it out laterally via the grip sections 712, 722 is also possible, for example, if the battery unit 3 is located on the seat tube 10.3.

[0106] In the illustrated energy storage assembly, not only can the battery unit 3 be easily and securely mechanically fixed to the battery holder 4 using the two locking levers 71, 72 and secured by the locking device 5, nor can the removal of the battery unit 3 from the battery holder 4 be facilitated. Rather, in the illustrated embodiment of the energy storage assembly, attaching the battery unit 3 to the battery holder 4 is also considerably easier. For example, the battery unit 3 can be removed from the bicycle frame 10 as explained above for charging at least one rechargeable battery provided in the battery unit 3.If the battery unit 3 is then to be reattached to the bicycle frame 10, as shown for example in Figure 12, it is sufficient to first press the first end face 3A with the locking levers 71 , 72 pivotably mounted on it against the locking part 41 in order to pre-fix the battery unit 3 to the battery holder 4.

[0107] 2024 461 P BRG196 Page 20

[0108] In this case, the two locking levers 71, 72 are elastically pre-tensioned in their locking positions, for example by means of torsion springs, each of which is arranged on a pivot bearing pin defining the pivot axis S1, S2. When the battery unit 3 is folded along the second mounting direction AR2 of Figure 12, the circular cylindrical locking pins 411 and 412 each come into contact with an inclined ramp surface of a guide section 371A, 372A of the first end face 3A, which laterally borders the associated pin opening 341A, 342A. The locking pin 411, 412 is thus guided in the direction of the pin opening 341A, 342A when the battery unit 3 is moved further along the second mounting direction AR2 by a user. In addition, each locking pin 411 , 412 comes into contact with an insertion chamfer 711 E or 721 E of an associated locking hook 711 , 721.As a locking pin 411, 412 slides along the insertion ramp 711E, 721E of the associated locking hook 711 or 721, the locking hook 711, 721, and thus the associated locking lever 71 or 72, which is spring-loaded into its locking position, is displaced against the applied preload force. In this case, the locking hooks 711, 721 and the locking pins 411, 412 are dimensioned and arranged such that, when the battery unit 3 is attached to the battery holder 4, the locking levers 71, 72 are pivoted beyond an intermediate position and then snap back into this intermediate position shown in Figure 6 as soon as the locking pins 411 and 412 have passed a respective locking hook 711, 721.

[0109] In the intermediate position shown in Figure 6, a respective locking hook 711, 721, with a clamping area 711 K or 721 K formed at its hook end, engages at least frictionally and thus clampingly, and optionally also positively, on an outer surface of the associated locking pin 411 or 412, so that the battery unit 3 is already held on the battery holder 4 and thus pre-fixed by means of the two locking levers 71, 72 in their intermediate positions. The battery unit 3 can therefore no longer fall out of the battery compartment 1020 without user intervention, with the locking levers 71, 72 having snapped back into their intermediate positions.

[0110] To move the locking levers 71, 72 from their intermediate positions into the locked positions, in which a locking hook 711, 721 partially engages the corresponding locking pin 411, 412 and closes the pin opening 341A, 342A, a user simply needs to grasp the protruding handle section 712, 722 – located here on the underside of the battery unit 3 – and adjust it towards the battery unit 3, i.e., push it away from each other. This causes the locking levers 71, 72 to rotate in opposite directions around the pivot axes S1, S2 into their respective positions.

[0111] 2024 461 P BRG196 Page 21

[0112] The locking positions are adjusted. With the corresponding pivoting movements, the locking openings 7200, 7100 and 7201, 7101 of the two partially overlapping bodies 710, 720 are also brought into paired alignment, so that the locking pin 56 can then lock the locking levers 71, 72 in their locking positions and thus also lock the battery unit 3 to the battery holder unit 4. Due to the sequence provided by the spring-loaded locking levers 71, 72, the mounting of the battery unit 3 to the battery holder 4 is comparatively simple, intuitive and ergonomic for the user.

[0113] To remove the battery unit 3, the handle sections 712, 722 can be grasped from the outside by a user in the locked positions of the locking levers 71, 72, in order to pivot the handle sections 712, 722 towards each other and thus the locking levers 71, 72 into their release positions when the locking mechanism has been released via the locking device 5. Due to an axial clamping of the battery unit 3 to the battery holder unit 4 via the locking levers 71, 72 in their locked positions, which is provided for tolerance compensation and will be explained in more detail below, the locking levers 71, 72 remain in their locked positions even when the locking mechanism is released. A user must therefore grasp the handle sections 712, 722 in order to pivot the locking levers 71, 72 from the locked positions to their release positions and thus be able to separate the battery unit 3 from the battery holder unit 4.

[0114] As illustrated in Figures 7, 8, and 9A-9B, the locking hooks 711, 721 and the locking levers 71, 72, in the illustrated embodiment, additionally serve to axially clamp the battery unit 3 to the battery holder 4, thus eliminating play. This axial clamping, relative to the longitudinal direction of the battery unit 3 and relative to the direction of the receiving space defined between the locking part 41 and the connecting part 43, is intended to ensure that the battery unit 4 remains permanently fixed to the battery holder 4 without play or rattling, in particular without relative movement to the connecting connector 430, which ensures the electrical contact of the battery unit 3. Furthermore, this allows battery units 3 of different sizes or manufactured with different tolerances to be fixed to the same battery holder 4 without rattling.Therefore, an axial distance between the locking part 41 and the connection part 43 does not need to be adjusted during the assembly of the battery holder 4.

[0115] 2024 461 P BRG196 Page 22

[0116] In the present case, a locking hook 711, 721 each has two lateral clamping ramps 7213, 7214. When a locking lever 71, 72 is moved from an intermediate position, which is shown, for example, in Figure 7 on an enlarged scale for the first locking lever 71, a clamping ramp 7213 facing the first end face 3A slides onto an inclined ramp surface of the first end face 3A in the form of a ramp 341 OA or 3420A. This results in a clamping force F1 acting parallel to the pivot axis S1 or S2 in the direction of the battery unit 3. A further clamping ramp 7214 opposite and facing the bearing block 410 of the locking part 41 on a locking hook 711, 721 slides simultaneously on a further ramp 4110 or 4120 when the locking lever 71, 72 pivots into its locking position. This ramp is formed facing a locking hook 711, 721 in the area of ​​a locking pin 411, 412 on the bearing block 410.By sliding along the further clamping ramp 7214 on the locking-part-side ramp 4110 or 4120, the locking lever 71 or 72, which is in its locked position, generates a clamping force F2 acting axially towards the locking part 41. The two locking levers 71 and 72 thus clamp the battery unit 3 axially against the battery holder unit 4 at two spaced-apart points by clamping forces F1 and F2, respectively. This secures the battery unit 3 to the battery holder unit 4 without rattling and also ensures that the battery unit 3 remains in its operating position on the battery holder 4 even under high acceleration forces on the bicycle frame 10.The ramps 3410A, 3420A and 4110, 4120 each extend in a circumferential direction to an associated pivot axis S1 or S2 and project ramp-like in relation to the respective pivot axis, so that the respective ramp 3410A, 3420A and 4110, 4120 projects further axially in a ramp-like manner in the respective pivot direction.

[0117] Figures 10A, 10B, and 11 illustrate in detail the interaction of the lock bolt with the locking lever-side locking openings 7201, 7101. In the release position of the locking levers 71, 72, as shown in Figure 10A, a pair of locking openings 7201, 7101 of the two locking levers 71, 72 do not overlap. Consequently, engagement of the lock bolt 56 is not possible in this position. Such engagement is only possible when both locking levers 71, 72 are in the locked position shown in Figure 10B. Now, the lock bolt 56 can be moved along an adjustment direction R5 by turning the key 6 in the lock cylinder of the locking device 5 into the two consecutive locking openings.

[0118] 2024 461 P BRG196 Page 23

[0119] 7201 and 7101 (through the opening 87.2 of the cover 8) engage and thus finally lock the battery unit 3 with the battery holder unit 4.

[0120] In a deviation from the illustrated embodiment, it can also be provided that the locking bolt 56, in its locking position, engages only in one locking opening 7201. This allows both locking levers 71, 72 to still be secured against pivoting into their release positions if the movements of the locking levers 71, 72 are coupled to each other. As soon as one locking lever 71, 72 is in the locked or release position, such a mechanical coupling ensures that the other locking lever 72, 71 is also in the respective position.
