Locking cylinder for a storage compartment

Description

[0001] The invention relates to a lockable storage compartment, in particular a battery compartment of an electric bicycle, with a locking cylinder, according to the preamble of claim 1.

[0002] An electrically powered bicycle, particularly an e-bike or pedelec, is typically equipped with a replaceable accumulator, i.e., a rechargeable electric battery. Such a accumulator can be mounted, for example, on a luggage rack or on a frame tube of the electric bicycle. To protect the accumulator against theft, the accumulator can be housed in a lockable storage compartment having an access opening on a wall through which the accumulator can be accessed. The access opening can be optionally closed by means of a lid. The lid can be movable, for example, pivotable like a flap, or sliding, or completely detachable.

[0003] The storage compartment and lid can generally take a variety of forms, for example, to form a substantially closed enclosure or to merely enclose the interior of the storage compartment in a cage-like manner, i.e., with remaining openings. When used on an electric bicycle, the storage compartment may also be referred to as a battery compartment, and the storage compartment may also be partially or fully integrated into the frame of the bicycle.

[0004] In order to lock the closed lid of the storage compartment, a locking cylinder can be provided which can be operated by means of a key.

[0005] Many applications, particularly the battery compartment of an electric bicycle, face the problem of limited space available for the locking mechanism. This can make it difficult to accommodate a locking mechanism with a locking cylinder that has a certain axial length and radial extension. Especially with the battery compartment of an electric bicycle, there is the additional problem that the locking cylinder should not protrude beyond the installation area on the outside to avoid a risk of injury to the user. The battery compartments of electric bicycles often have thin walls, which inevitably results in a certain axial projection of the locking cylinder into the interior.

[0006] DE 10 2005 014 899 A1 shows a storage compartment according to the preamble of claim 1. FR 2 386 670 A1, GB 2 432 881 A, US 6 523 381 B1 and EP 2 500 246 A1 show similar storage compartments and / or locking cylinders therefor.

[0007] It is an object of the invention to provide a lockable storage compartment, in particular a battery compartment of an electric bicycle, with a locking cylinder which, when actuating the locking cylinder, provides the user with haptic feedback about the reaching of a locking position of the bolt and a mechanical stabilization of the bolt in the locking position.

[0008] This object is achieved by a storage compartment having the features of claim 1.

[0009] The invention thus relates to a lockable storage compartment, in particular a battery compartment of an electric bicycle, which has at least one wall with an access opening, furthermore a movable lid for closing the access opening, and a locking cylinder for locking the lid.

[0010] According to the invention, the locking cylinder of the storage compartment comprises a cylinder housing, a rotor, and a bolt. The rotor is mounted in the cylinder housing for rotation about a cylinder axis. At the rear of the locking cylinder, the rotor has a drive section to which the bolt is mounted in a rotationally fixed manner. The bolt projects radially beyond the cylinder housing relative to the cylinder axis. Starting from the drive section of the rotor, the bolt is angled toward the front of the locking cylinder.

[0011] According to the invention, the locking cylinder is mounted on the movable lid of the storage compartment in order to be able to selectively lock or unlock the lid in a closed position, in which the lid closes an access opening in the storage compartment. The locking cylinder can have a key insertion opening on its front side in order to be able to insert an assigned key. By rotating the rotor using the assigned key, the bolt can be pivoted directly between a locking position and an unlocking position. In the locking position, the bolt engages with its free end behind an adjacent laterally located wall section of the storage compartment in order to lock the lid against opening. In the unlocking position, the bolt can be pivoted away from the surrounding wall of the storage compartment orbe aligned with a section of the lid to allow the lid to be opened or removed.

[0012] The locking cylinder thus has a bolt that is firmly connected to the rotor and that extends from the rear drive section of the rotor not only in the radial direction relative to the cylinder axis, but also towards the front of the locking cylinder. Overall, this results in an angled shape of the bolt, which, compared to a bolt that only extends transversely, runs relatively closely along the cylinder housing to the area - in particular to the adjacent wall section of the storage compartment - where the bolt is intended to fulfill its locking function. Thus, only minimal installation space is required for the bolt's movement path in the vicinity of the locking cylinder for the locking mechanism (locking cylinder with bolt).Furthermore, such a design of the locking cylinder can, in optional embodiments, ensure that the fastening plane of the locking cylinder is located close to the front of the locking cylinder and the locking cylinder therefore projects at most slightly beyond the fastening plane, wherein the bolt can extend within the storage compartment up to close to the fastening plane in order to be able to engage behind an adjacent wall section of the storage compartment.

[0013] In the following, various embodiments are explained, which can also be advantageously combined with one another.

[0014] In some embodiments, the cylinder housing can have a specific longitudinal extension along the cylinder axis, wherein the bolt, starting from the drive section of the rotor, extends along the cylinder housing over at least 60%, in particular over at least 70% or 80%, of the longitudinal extension of the cylinder housing in the direction of the front side of the locking cylinder.

[0015] In some embodiments, the locking cylinder may have a stop collar on its front side, which is designed to bear against an outer side of the lid of the storage compartment when the locking cylinder is in the assembled state. The locking cylinder further comprises a securing element, in particular a lock nut or a snap ring, which is designed to bear against an inner side of the lid of the storage compartment when the locking cylinder is in the assembled state in order to secure the locking cylinder to the lid. In such embodiments, the bolt can protrude from the drive section of the rotor along the cylinder axis at least to the level of the securing element, or even to the level of the stop collar of the locking cylinder (adjacent or overlapping).

[0016] In the aforementioned embodiments, the bolt can therefore have a far-reaching axial extension along the cylinder axis in the direction of the front of the locking cylinder in order to fulfil the required locking function there with its free end, whereby only little radial installation space is required for the pivoting movement of the bolt (between the locking position and the unlocking position) in the rear area of ​​the locking cylinder.

[0017] According to the invention, the latch is cranked and, extending from the drive section of the rotor, has a fastening section with which the latch is fastened to the drive section; furthermore, a connecting section running along the cylinder axis and oriented obliquely with respect to the cylinder axis; and, at its free end, a locking section for the required locking function. The locking section extends perpendicular to the cylinder axis. The locking section has—as will be explained below—a detent elevation.

[0018] The fastening section of the latch can be positively connected to the drive section of the rotor with respect to the rotational movement around the cylinder axis. This ensures that the latch is securely attached to the rotor for the pivoting movement (between the locking position and the unlocking position). The fastening section of the latch can be fixed to the drive section, in particular by means of an axially aligned fastening screw, in order to also ensure stable axial fixation.

[0019] In some embodiments, the latch may have a respective stiffening bead between the fastening portion and the connecting portion, and / or between the connecting portion and the locking portion. This achieves high stability despite the angled shape of the latch, particularly with respect to axial loads (i.e., along the cylinder axis) in the event of a forced opening attempt on the storage compartment or the lid.

[0020] According to the invention, the locking portion of the bolt has a detent protrusion. This allows a simple locking of the bolt with the installation environment when the bolt is in an end position, in particular in the locking position or in the unlocking position. Thus, when operating the locking cylinder, the user can receive haptic feedback about reaching the respective end position of the bolt, and the bolt can be mechanically stabilized in a specific position, for example, in a zero position of the locking cylinder, in order to easily remove the assigned key from the locking cylinder.

[0021] Due to its angled shape, the bolt can have such inherent elasticity that it allows sufficient temporary deflection and thus pre-tensioning along the cylinder axis so that the locking section of the bolt can enter into a snap-fit ​​connection with the installation environment.

[0022] According to the invention, the storage compartment has on the inside a recess complementary to the locking elevation of the bolt for the locking connection with the bolt.

[0023] The latch can engage, particularly as a result of a pivoting movement after reaching the locking position, into the complementary recess on the inside of the storage compartment. In the case of the engaging protrusion, the latch can apply a certain contact force to the inside of the storage compartment during the pivoting movement due to a certain preload.

[0024] The locking protrusion of the bolt forms a protrusion along the cylinder axis.

[0025] According to the invention, the engagement elevation forms a convex elevation in the direction of the front side of the locking cylinder relative to a base surface of the locking section.

[0026] In some embodiments, the engagement protrusion may have a longitudinal shape extending along a radial direction relative to the cylinder axis. Such a shape and orientation of the engagement protrusion are easily achieved on the elongated latch with tight tolerances.

[0027] As for the further design of the locking cylinder, the rotor can have a keyway with a key insertion opening at the front. The locking cylinder can generally be constructed according to different locking principles.

[0028] Particularly advantageous in combination with the angled bolt is an embodiment in which the locking cylinder is a disc cylinder having a plurality of disc tumblers rotatable about the cylinder axis and a locking pin aligned parallel to the cylinder axis and displaceable radially to the cylinder axis, wherein each disc tumbler has a central receiving opening for receiving the associated key and a circumferential recess for receiving the locking pin. In such a locking cylinder, the individual tumblers are designed as flat discs arranged closely one behind the other along the cylinder axis, so that the locking cylinder can have a short axial length. The cylinder thus protrudes only minimally into the interior of the storage compartment, and the angled part of the bolt - in particular the aforementioned connecting section - can have a correspondingly short length with high stability.

[0029] In such a disc cylinder, the locking pin can block the rotor against rotational movement in a radially outer blocking position and release the rotor for rotational movement in a radially inner release position, wherein the disc tumblers can be rotated between a locking position and an unlocking position, and wherein the locking pin can only be moved into the release position if (after sorting the disc tumblers by means of the associated key) all disc tumblers are in their unlocking position, in which the circumferential recess of the respective disc tumbler is aligned radially to the locking pin.

[0030] As explained, the storage compartment and the lid can take on a variety of forms (e.g. closed or grid-like) and can be at least partially integrated into another installation environment (e.g. bicycle frame).

[0031] In some embodiments, the cylinder housing may have a non-circular cross-section, allowing the locking cylinder to be held in the cover in a form-fitting and thus rotationally fixed manner. In particular, the cylinder housing may be flattened on two sides, at least in an axial section near the front of the locking cylinder.

[0032] In some embodiments, on an outer side of the storage compartment, the wall and the lid can extend coplanarly in a common (flat or curved) extension plane along a parting line formed between the wall and the lid, wherein the lid has a fastening portion with a fastening opening in which the locking cylinder is received. In such embodiments, the fastening portion of the lid can be recessed relative to the common extension plane of the wall and lid such that the front side of the locking cylinder is arranged substantially flush with the common extension plane of the wall and lid. This minimizes the risk of injury from the part of the locking cylinder protruding on the outer side of the storage compartment.

[0033] According to the invention, the storage compartment has a recess on its inside for engagement with the latch. This allows the latch to engage with the recess in the locked position and thus be stabilized in the end position. Thus, a latching connection with the aforementioned latching protrusion, which is formed at the free end of the latch, is provided on the inside of the storage compartment.

[0034] On the inside of the storage compartment, the wall and the lid can extend coplanarly in a common plane of extension along a joint formed between the wall and the lid, at least in the area of ​​the bolt's path of movement. The bolt can thus easily traverse the joint in both directions, even in the event of pre-tensioning toward the front of the locking cylinder and a corresponding force being applied to the inside of the storage compartment.

[0035] The invention also relates to an electric bicycle with a lockable storage compartment of the type described.

[0036] The invention is explained below by way of example with reference to the drawings, wherein identical or similar elements are identified by the same reference numerals.

Figs. 10 and 11 show perspective views of a bolt of a second embodiment of the locking cylinder according to the invention. Fig. 12 shows the inside of a wall section of the storage compartment without a lid. Fig. 13 shows a sectional view of the storage compartment with the lid locked. Fig. 14 shows a perspective view of the inside of the lid of the storage compartment without a locking cylinder.

[0037] In Fig. 1an electric bicycle 11 is shown, which has an electrical energy storage device in the form of an accumulator 17 ( Fig. 2 ) which is housed in a lockable storage compartment 15. The storage compartment 15 thus forms a so-called battery compartment and can be arranged, for example, on a frame section 19 of the electric bicycle 11. The storage compartment 15 does not necessarily have to form a completely enclosed enclosure, but can also be partially or completely integrated into the frame section 19.

[0038] For example, the storage compartment 15 can be designed in the manner of a hood that surrounds the accumulator 17 on several sides and is mounted with an open bottom on the frame section 19. Such a storage compartment 15 is shown in Fig. 2 and 3 shown, wherein the storage compartment 15 is detached from the frame section 19 and in Fig. 2 the viewing direction points from below into the interior of the storage compartment 15. Fig. 3 shows the outside of the storage compartment 15. In this embodiment, the storage compartment 15 has the shape of a housing that is open at the bottom.

[0039] The storage compartment 15 has an access opening 21 closed by a movable lid 23. A separating joint 27 runs between the curved lid 23 and the curved wall 25 of the storage compartment 15. When the lid 23 is open or removed, the accumulator 17 can be removed or inserted through the access opening 21.

[0040] By means of a locking cylinder 31 which can be rotated by a key 29, the cover 23 can be locked in the Fig. 2 and 3shown closed position. For this purpose, the locking cylinder 31 has a bolt 33 which rests against the inside of a wall section 35 of the storage compartment 15 adjacent to the lid 23.

[0041] As from Fig. 3 As can be seen, the wall 25 and the lid 23 extend along the separating joint 27 coplanar to one another on the upper side of the storage compartment 15, wherein the lid 23 has a fastening section 37 with a fastening opening 39 in which the locking cylinder 31 is received. The lid 23 has a recess 41 on the fastening section 37, in which the fastening opening 39 is arranged and on which the locking cylinder 31 is mounted such that the Fig. 3 visible front side 43 of the locking cylinder 31 is arranged substantially flush with the common extension plane of the wall 25 and the lid 23 on the upper side of the storage compartment 15.

[0042] Based on the Fig. 4 to 9 The locking cylinder 31 according to a first embodiment will now be explained in more detail (not an embodiment of the invention).

[0043] The locking cylinder 31 has a cylinder housing 51 and a rotor 53 mounted in the cylinder housing 51 for rotation about a cylinder axis A. On the front side 43, the locking cylinder 31 has a key insertion opening 55 through which the associated key 29 can be inserted in order to rotate the rotor 53 relative to the cylinder housing 51. For fastening the locking cylinder 31 to the fastening section 37 of the cover 23 ( Fig. 3 ), the locking cylinder 31 has on its front side 43 a stop collar 59 covered by a cylinder cap 57, which in the assembled state of the locking cylinder 31 within the recess 41 ( Fig. 3) on the outside of the cover 23. Furthermore, the locking cylinder has a securing element in the form of a lock nut 61, which in the assembled state of the locking cylinder 31 rests on the inside of the cover 23 ( Fig. 2 ) to fix the locking cylinder 31 to the cover 23. The cylinder housing 57 has two flattened portions 63 distributed around the circumference, on which the locking cylinder 31 is inserted into the fastening opening 39 of the cover 23 ( Fig. 3 ) is held in a form-fitting manner and is therefore non-rotatable.

[0044] The rotor 53 has a drive section 67 on the rear side 65 of the locking cylinder 31. The bolt 33 is mounted on the drive section 67 in a rotationally fixed manner. For this purpose, a fastening section 69 of the bolt 33 is positively connected to the drive section 67 of the rotor 53 and fixed to the drive section 67 by means of an axially aligned fastening screw 71.

[0045] Starting from the drive section 67 of the rotor 53, the bolt 33 is angled towards the front side 43 of the locking cylinder 31, so that the bolt 33 not only projects beyond the cylinder housing 51 in the radial direction with respect to the cylinder axis A, but also extends towards the front side 43 of the locking cylinder 31. Overall, this results in an angled shape of the bolt 33 with a partially oblique course with respect to the cylinder axis A, wherein the bolt 33 runs at a small radial distance along the cylinder housing 51 and closely adjacent to the locking nut 61 up to the level of the cover 23 or the wall section 35 of the storage compartment 15, at which the bolt 33 is intended to fulfill its locking function.

[0046] In relation to the longitudinal extent L of the cylinder housing 51 along the cylinder axis A, the bolt 33, starting from the drive section 67 of the rotor 53, can extend, for example, over approximately 85% of the longitudinal extent L of the cylinder housing 51 in the direction of the front side 43 of the locking cylinder 31 ( Fig. 8 ). As a result, the bolt 33 projects from the drive section 67 along the cylinder axis A beyond the locking nut 61 to the level of the stop collar 59 of the locking cylinder 31.

[0047] Viewed in side view, the latch 33 is cranked and, starting from the drive section 67 of the rotor 53, has the fastening section 69 with which the latch 33 is fastened to the drive section 67; furthermore, a connecting section 73 extending obliquely with respect to the cylinder axis A; and a flat locking section 75 which extends at least substantially perpendicular to the cylinder axis A.

[0048] Due to this shape of the bolt 33, only minimal installation space is required in the vicinity of the locking cylinder 31 for the movement path of the bolt 33. Furthermore, such a design of the locking cylinder 31 can ensure that the fastening plane of the locking cylinder 31 is located near its front side 43 and the locking cylinder 31 thus protrudes at most slightly beyond the fastening plane, wherein the bolt 33 can extend close to the fastening plane in order to be able to engage behind an adjacent wall section 35 of the storage compartment 15 in the locked position.

[0049] In order to achieve high stability, particularly with regard to axial loads in the event of a violent opening attempt on the storage compartment 15 or the lid 23, despite the angled shape of the latch 33, the latch 33 has a respective stiffening bead 77 between the fastening section 69 and the connecting section 73 and between the connecting section 73 and the locking section 75.

[0050] In the embodiment shown, the locking cylinder 31 is designed as a disc cylinder (cf. Fig. 9). For this purpose, the locking cylinder 31 has, along the cylinder axis A, a plurality of disc tumblers 81 rotatable about the cylinder axis A and a locking pin 83 aligned parallel to the cylinder axis A and displaceable radially to the cylinder axis A. The disc tumblers 81 are rotatably mounted axially closely adjacent to one another within a rotor sleeve 85, which is positively and thus non-rotatably connected to a drive part 87 on which the drive section 67 is formed. As a result of this configuration, the locking cylinder 31 has only a small axial depth in the direction of the storage compartment 15.

[0051] Based on the Fig. 10 to 13 An advantageous further development of the locking cylinder 31 will now be explained.

[0052] In this embodiment, the bolt 33 has a locking protrusion 91 on the locking portion 75. The locking protrusion 91 forms a convex protrusion in the direction of the front side 43 of the locking cylinder 31 relative to a base surface of the locking portion 75. In the embodiment shown, the locking protrusion 91 has a longitudinal shape that runs along a radial direction with respect to the cylinder axis A ( Figs. 10 and 11 ). In the locking position of the latch 33, the latch 30 engages by means of the engagement protrusion 91 with a complementary recess 93 formed on the inside of the wall section 35 of the storage compartment 15 adjacent to the lid 23 ( Fig. 12 and 13 ).

[0053] Thus, upon reaching the locking position, the bolt 33 slides into the recess 93 of the wall section 35, and the user can sense the reaching of the locking position of the bolt 33 upon actuation of the locking cylinder 31 using the key 29. Furthermore, the bolt 33 can thus be mechanically stabilized in the locking position, whereby in the so-called zero position of the locking cylinder 31, which corresponds to the locking position of the bolt 33, the key 29 can be easily removed from the locking cylinder 31.

[0054] Due to its angled shape, the latch 33 can have such inherent elasticity that the latch 33 experiences a temporary deflection while traveling along the inside of the wall section 35 of the storage compartment 15 and, when the locking position is reached, engages in the recess 93 in a force-fitting manner.

[0055] A recess corresponding to the recess 93 can also be provided on the inside of the cover 23 for the unlocking position of the latch 33 (not shown).

[0056] Fig. 14 shows the non-circular cross-section of the fastening opening 39 of the cover 23, in which the cylinder housing 51 with the lateral flattenings 63 ( Fig. 9 ) can be positively and thus non-rotatably received. List of reference symbols
