Description

safety lock

The present invention relates to a security lock for a provided with an electrical energy storage means of transport, in particular an e-bike or motorcycle, wherein the security lock has a lock housing to which a securing means, in particular in the form of a security chain, a securing bracket, a safety rope or a rigid member a folding lock, fastened and / or releasably attachable, and the lock housing also has a securing device for locking or locking the security lock.

A lock for connecting electric bicycles is from the

DE 102012025083 AI previously known. This lock is part of a charging device for the battery-powered electric bicycle. The charging device has a stationary installed carrier structure, which has a holding eye, in which a transmitting induction coil for inductive energy transmission is arranged. The lock has a aufschließbaren ring in which a receiving coil is arranged. The open-circuit ring is pulled through the retaining lug of the stationary installed carrier structure and then completed. A voltage which is conducted via a charging cable to the rechargeable battery of the electric bicycle is induced in the receiving coil integrated in the unlockable ring via the transmitting induction coil arranged in the holding eye. A disadvantage of this embodiment is the low coupling between the transmitting induction coil and the receiving coil. In addition, both the receiving coil and the transmitting induction coil are each part of the mechanical fuse. This requires training in the mechani- Fuse consideration to be taken to the inductive energy transfer device, which inevitably not optimal mechanical protection can be achieved.

A stationary securing device for an electric bicycle is known from EP 0 741 441 A2, in which a pivotable arm is arranged on a stationary station and can be fastened with its free end to the bicycle frame in the region of the saddle mount. The free end encompasses the saddle seat by an angular range of about 270 ° and carries a primary winding. In the saddle a secondary winding is arranged. If the electric bicycle is attached to the securing device by means of the pivotable arm, a voltage in the secondary winding can be induced by means of the primary winding, by means of which a battery of the electric bicycle is chargeable. The disadvantage is that the securing device is mechanically complex and is also stationary, and thus the bike can not be mechanically secured against theft at any location.

Object of the present invention is to provide a security lock with which a means of transport as with any mechanical lock on trees, piles, fences, etc. can be mechanically secured against theft and beyond a secure way to inductive energy transfer with good coupling of a primary-side Loading device on the means of transport permits.

This object is achieved with a security lock according to claim 1. Advantageous embodiments of the security lock according to claim 1 result from the features of the subclaims.

The invention is advantageously characterized in that a secondary winding for inductively receiving electrical energy is arranged in the lock housing itself or in a winding housing fastened or arranged on the lock housing. By arranging the secondary winding in the lock housing or in a, in particular arranged thereon, the winding housing is optimally protected against external damage. The housing surrounding the secondary winding can optimally be used for the inductive Be formed energy transfer, ie that the secondary winding and a possibly be provided in the housing part spool core is arranged in the housing, that there is an optimal coupling between the arranged in the housing coil assembly and the primary coil arrangement fed by a source, so that the charging time as short as possible is and only very low energy losses occur. To achieve this, the coil assembly is so arranged in the lock or winding housing, which results in the smallest possible gap or air gap between the magnetic poles of the secondary and primary coil arrangements, as soon as the Schlossbzw. Winding housing has been brought to the primary-side charging station in the correct position.

Advantageously, the lock or winding housing is designed such that it can be arranged or fastened only in one position on the charging station, so that optimum orientation of the primary and secondary coil arrangements is guaranteed by the shape and / or provided fastening devices.

The components for inductive energy transfer are functionally separated from each other by the components for mechanical securing and formation of the actual lock, even if they can be arranged in a housing. As a result, the security lock can be optimally formed, both with regard to the safety aspects and with regard to a good inductive energy transfer.

In the lock housing or the winding housing, at least one coil core can be arranged, around which the secondary winding is wound. Of course, instead of a wound coil core, a plate-shaped arrangement of ferrite may be provided, to which the secondary side winding for energy transmission is arranged in parallel, as is already known from pickups for motor vehicles.

The secondary housing receiving the lock housing or the winding housing is preferably formed of a hard material and / or torsionally rigid. If a separate winding housing is used, this can be achieved, for example, by means of a latching connection releasably attached to the lock housing. be taken, so that if necessary, against another winding housing, which, for example, another secondary winding, for. B. for another line voltage, has, can be replaced or replaced. It is also conceivable that the winding housing is permanently attached to the lock housing, so that it can only be separated again by destruction of this. It is also optionally possible for the winding housing and the lock housing to have mutually corresponding contacts for energy transmission and optionally for data transmission. The data transmission can also be done by radio between the winding housing and lock housing.

Advantageously, the lock housing by means of a first securing means, in particular in the form of a security chain, a securing bracket, a safety rope or a rigid member of a folding lock, fastened to the charging station. With the securing means can also be secured at the same time the means of transport, in which z. As the circlip, the safety rope, the safety chain or the rigid members of the folding lock are pulled through the frame or the spokes and thus securely surround the frame or the wheel. In the case of the securing bracket this is inserted with two free ends in corresponding receptacles of the lock housing and locked by means of the lock. When using a security chain, a safety rope or rigid links of a folding lock is always or at least in the locked state of the castle one end of the safety chain, the safety rope or a rigid member inextricably linked to the lock housing, in the sense that it only by destroying the connection Lock housing is separable. The other end of the safety chain, the safety rope or the folding chain formed from the rigid links is detachable and lockable fastened to the lock housing, as is known from commercial chain rope and folding locks ago.

It is also possible that in addition to the first securing means described above, which is provided for safe attachment of the lock housing to the charging station, another securing means, for. B. in the form of a safety chain, a safety rope or rigid folding members, at least with one end is permanently attached to the lock housing, in the sense that it is separable only by destruction of the lock housing. The other end the safety chain, the safety rope or the folding chain formed from the rigid links is releasably and lockable fastened to the lock housing, as is known from commercial chain rope and folding locks ago. It is also conceivable that the further securing means is a U-shaped bracket, which can be secured against being pulled out with its two ends in the lock housing. The further securing means serves to secure the means of transport, in particular an electric bicycle, on

Lock housing and / or the charging station.

It is also possible that the first securing means is at least one securing bolt. The securing bolt may e.g. be pushed out of the lock housing or swung out to intervene in an undercut or a recess of the charging station, so that a positive connection between the lock housing and charging station, and thus the lock housing without the corresponding key or code only by force and concomitant destruction of the charging station or Lock housing is removable.

If the first end of the further securing means is secured to the lock housing in particular insoluble, the free end of the further securing means may comprise an eyelet whose window-like opening is particularly adapted to the outer contour of the lock housing and designed such that the lock housing is hindurchschiebbar through the eyelet. If the first securing means is then fastened to the lock housing or moved out of the lock housing or swung out, the lock housing can no longer be pushed through the eyelet. The further securing means thus forms a loop, which is unauthorized to open and with which a means of transport can thus be attached to any stationary objects.

It is also possible that the lock housing by means of the winding housing or an additional securing means to the charging station is lockable fastened. By attaching the winding housing or the additional securing means on the lock housing a unit is formed by their formation at the same time a positive connection is formed by the unit can be locked at a primary-side stationary charging station, whereby unauthorized removal of the lock housing is prevented by the charging station. It is of course important to ensure that the individual components are sufficiently stable and formed against external destruction. By means of the further locking means arranged on the lock housing, the means of transport can then be completed or fastened to a stationary object.

The security device for locking the security lock can be a cylinder lock, a combination lock or an electric

Locking device, in particular with a keyboard or a wireless communication interface, be.

The charging station can also optionally communicate with the security lock. Thus, via the security lock, an identification with respect to the charging station or a remotely located data processing device can take place and e.g. the withdrawn electrical power is billed or booked. The communication between the charging station and the security lock can take place via the primary and secondary windings and / or via radio.

It is also possible that a communication between an external mobile communication device, such as e.g. a mobile phone or a smartphone, and the charging station or the remote data processing device, in particular for identification and power billing takes place. Thus, in a development of the invention z. B. the charging status via the charging station or the data processing device are queried. Also, the owner or owner of the means of transport and / or a security authority or company may be notified of an attempted, attempted and / or successful theft.

It is also possible as an alternative or in combination with the previously described embodiments that the security lock itself has a communication device. About this can, for example, unlocking the security lock by means of an external mobile communication device such. As a mobile phone or a smartphone, done. Also can in particular the charging status or the state of the security lock of the external mobile communication device can be transmitted via the communication device.

Various possible embodiments of the security lock according to the invention will be explained in more detail below with reference to drawings.

FIG. 1 shows on the left an electric bicycle 2, which is connected to a safety lock 4, 5, 6 according to the invention at a pile 1. Right in FIG. 1 shows the security lock 4, 5, 6, the charging station 3 and the pole 1 without the electric bicycle 2. At the pile 1 itself, a charging station 3 is arranged, which has a safety bar 6, which is fixed with its one strap end 6a fixed to the charging station 3. The other strap end 6b can either also be fastened to the loading station 3 or the pole 1, as shown in FIGS. 2a and 2b. The fasteners are designed such that the charging station 3 and / or the bracket 6 can be solved only by special tools or destruction. The security lock has a lock housing 4, a first security means 7, with which the lock housing 4 can be fastened securely to the charging station 3. The first safety means 7 is designed as a bracket and engages around the bracket 6 of the charging station 3 around and is anchored with its two free bracket ends 7a, in the lock housing 4, as shown in Figure 2c. Of course, it is possible to replace the bracket 7 by a chain or other fastening means. In the lock housing 4, as shown in Figure 2c, a cylinder lock 15 is arranged, by means of which the free strap ends 7a are lockable, so that the cylinder lock 15 is not opened without the corresponding key and thus the lock housing 4 can not be removed from the charging station 3.

At the lock housing 4, a further securing means 5 is attached in the form of a chain with its first end 5a on the lock housing 4, wherein at the free end 5b of the chain 5, a rectangular eyelet 24 is attached. The cross section of the eyelet 24 is dimensioned and designed so that the lock housing 4 can be inserted through the eyelet 24 just as long, if previously the bracket 7 has been removed from the lock housing 4. The chain 5 then forms a loop which can be placed around a frame bar 2 a of the electric bicycle 2. Once the lock housing 4 is secured in the charging station 3 against unauthorized removal by means of the first securing means 7, and the electric bicycle 2 is securely fastened to the charging station 3 and the pile 1.

FIGS. 2a and 2b show schematic illustrations of the charging station once without the lock housing 4 inserted in the charging station (FIG. 2a) and with the lock housing 4 (FIG. 2b) inserted. In the lock housing is a primary coil assembly 10, 11 is arranged, wherein the coil arrangement has a U- or C-shaped coil core 10 and a wound around the coil core 10 coil winding 11, which is connected via a feed line 12 with a ballast 9 in combination. The charging station 3 is supplied via the arranged in the pile 1 electric cable 8 with electrical energy. The cable 8 may additionally include data lines. However, it is of course also possible to provide separate data and power cables for supply and connection to the charging station. It is also possible that the charging station 3 communicates by means of wireless communication with a central data processing system.

The coil arrangement 10, 11 is arranged above a window opening 15 and around the cavity of the housing 3a adjoining it, the magnetic poles 13, 14 of the primary-side coil arrangement 10, 11 being arranged laterally next to the window opening 15. At the bottom of the housing 3a of the securing bracket 6 is arranged such that the lock housing 4, as shown in Figure 2b, is still inserted from below the bracket 6 in the opening 3b of the housing 3a of the charging station 3. The bracket 6 is fastened with its one end 6a to the housing 3a of the charging station 3 and with its other end 6b to the pile 1.

As can be seen in Figure 2b, the lock housing 4 is pushed with its upper portion 4a in the cavity formed by the opening 3b of the housing 3a of the charging station 3 and can then be secured with the first securing means in the form of a bracket 7 on the bracket 6 against unauthorized removal , For this purpose, a cylinder lock 15, which is arranged in the lock housing 4 for locking and opening the padlock 7.

FIG. 2 c shows a schematic representation of the lock housing 4, on whose upper side a coil arrangement 16, 17 is arranged in the upper section 4 a. The coil assembly consists of a coil core 16 and a cylindrical winding 17 which is formed as a secondary winding. The coil core 16 forms with its lateral end faces 16a, 16b magnetic poles, which are arranged opposite the poles 13, 14 of the coil assembly 10,11 of the charging station 3, provided the lock housing 4 in the charging station 3 is used. As soon as a current flows through the winding 11 of the charging station 3, this current generates a magnetic flux which induces a voltage in the secondary winding 17, which is supplied either directly via the charging cable 18, 20, 21 to the electric bicycle 2 or first to a downstream electronic unit 19 is, which generates a DC voltage from the induced AC voltage, which is then supplied via the cables 20, 21 and the plug 22 to the electric bicycle 2. It is important to ensure that the poles 16a, 16b of the secondary coil assembly are arranged as close as possible to the poles 13, 14 of the primary coil assembly, so that the air gaps between the poles are as small as possible and thus the magnetic losses are kept small.

At the portion 4a of the lock housing 4, in which the secondary coil assembly 16, 17 is arranged, locking lugs 25 are provided outside, which engage in corresponding (not shown) recesses in the opening 15 of the housing 3a of the charging station, so that the lock housing 4 without Secured by means of the first securing means 7 is provisionally held. As a result, the fastening of the bracket 7 is facilitated on the lock housing 4, since the lock housing 4 does not have to be held relative to the loading station 3 when mounting the bracket 7.

At the rear of the lock housing 4, the cylindrical recesses 26 are arranged, in which the strap ends 7a of the bracket 7 can be inserted. The exact design of the latching and locking of the bracket 7 in the openings 26 is not described at this point, since they are well known from the prior art, in particular of U-locks.

As can be seen from FIG. 2 c, the secondary-side coil arrangement 16, 17 is spatially separated from the bracket attachment 26, 15 in the lock housing 4, so that the individual lock housing areas can each be designed optimally for their respective function, ie energy transmission and mechanical security , Of course, it is also possible to arrange the secondary-side coil assembly in a separate winding housing, which z. B. by means of locking, on the

Lock housing 4 can be fastened. Also, electrical contacts to the electrical connection of the arranged in the winding housing coil assembly may be provided with the arranged in the lock housing electronics both on the winding housing and on the lock housing.

It is of course also possible to integrate the secondary-side coil arrangement 16, 17 together with the bracket attachment 26, 15 in a housing part.

On the underside of the lock housing 4, a further second securing means 5 is attached in the form of a chain with its first end 5a. At the second free end 5b of the chain 5, the eyelet 24 is fixed, which is formed by their dimensions forth so that the lock housing 4 can be pushed through the eyelet 24, provided that the bracket 7 is separated from the lock housing. The charging cable 21 may be guided at least partially through the chain links of the chain 5. However, it is of course also possible that the charging cable 21 ^{'is led out} freely from the lock housing 4, as shown in dashed lines.

Of course, instead of the chain 5, the further securing means may also be a bow, rope or a folding chain consisting of rigid elongated members. It is also possible that instead of the eyelet 24 in the lock housing 4 latched and lockable lock member is arranged on the chain 5, as is the case in the embodiment described below.

Figures 3a to 3c show an alternative embodiment of the security lock and the required charging station. As can be seen from FIG. 3 a, the housing of the charging station 3 has a recess 30 on its underside into which the lock housing 40 can be inserted. In the charging station 3, the primary coil assembly 10, 11 is arranged above the recess 30. The primary-side coil core 10 is U-shaped, wherein windings 11 are wound around the free legs, which are fed via the supply line 12 from the ballast electronics 9. The coil core 10 forms, with its lower end faces, magnetic poles 13 which cooperate with the magnetic poles 41a of the coil arrangement 41, 42 of the lock housing as soon as the lock housing is inserted in the recess 30. In the lock housing is also a U-shaped coil core 41 with cylindrical Winding 42 arranged, the magnetic poles 41a facing the poles 13. The distance between the magnetic poles 13, 41a should be as small as possible.

On the lock housing 40, a chain 45 is attached as a further securing means, at the free end of a lock part 48 is arranged, which in the lock receptacle 49 of the lock housing 40 in the arrow direction can be inserted. The lock housing has a lock cylinder 44 with which the bolts 43 can be pushed laterally out of the lock housing into corresponding recesses 30a of the housing of the charging station 3, as shown in FIG. 3c. This creates a positive connection against the arrow direction, whereby the lock housing 40 is not removable without the key 49 or destruction of the charging station. With the drive out of the bolt 43, the lock body 48 is also secured in the receptacle 49 so that on the one hand by means of bolts 43, the lock housing is securely attached to the charging station 3 and on the other hand by means of the chain 45, for example, an electric bicycle on the lock housing 40 can be fastened. It is of course possible that the locking mechanism is designed such that the lock body is still inserted into the receptacle 49 even after completing the cylinder lock 44, so that first the lock housing in the charging station can be anchored and locked, after which the chain 45 through the Bicycle frame pulled through and the lock body 48 in the receptacle 49 einklick- bar is. Instead of the chain 45, of course, a rope or rigid members of a folding lock can be provided.

The safety lock according to the invention can be used in the prescribed embodiments without the charging station as a security lock, as by means of the further securing means in the form of chain 5, and 45 a closed and lockable loop can be formed by means of which, for example, an electric bike safely on a bicycle stand, tree , Railing, etc. is attachable.

If, as shown in Figures 1 and 2c, on the chain 5, 45, an eyelet 24 is fixed, which can be pushed over the lock housing 4, a non-openable loop can also be formed here, if after Pushing through the lock housing 4 through the eyelet 24 of the bracket 7 has been inserted and completed in the lock housing.

FIG. 4 shows an alternative embodiment in which the secondary winding 17 and the associated coil core 16 are arranged in a separate winding housing 50. Of course, it is also possible that in the winding housing 50 further electronic components are arranged, such as. As a rectifier or additional electrical components, so that no further electrical components are to be arranged in the lock housing 4 except the necessary connection cable. The winding housing 50 is fastened or attachable to the lock housing 4. The attachment can z. B. by means of a latching or snap connection 51, 51 a done, which z. B. on the underside of the winding housing 50 and the top 4b of the lock housing 4 are arranged correspondingly. This compound can be designed such that it can be solved only with special tools. For electrical connection of the secondary winding 17 and arranged in the lock housing 4 electronics 19 and cable contacts 52, 53 are provided on the winding housing 50 and the lock housing 4. The arrangement of the secondary winding and optionally the downstream electronics in a separate winding housing can be used, inter alia, to use a winding housing for different lock housing. Likewise, different winding housing 50 may be provided with different secondary windings, electrical components and / or outer contour, all of which can be fastened or connected to a standardized lock housing 4. The different winding housings 50 can each be adapted to differently configured charging stations.
