Description

The present invention relates to an electronic padlock for two-wheelers. The U-lock comprises a lock body and a striker that is movable relative to the lock body between a closed position and an open position, the lock body having a housing, a locking mechanism by means of which the striker can be locked to the lock body in the closed position, and an electrical unit , wherein a molded part is positively inserted into the housing, which has a plurality of receptacles in which a plurality of components of the electrical unit are accommodated in a form-fitting manner.

Such a U-lock is known, for example, as a U-shackle lock which has a substantially U-shaped striker. A U-lock of the type mentioned can also be designed as a hinged lock which has a hinged bar bracket with several hinged bars connected to one another in a pivotable manner. A U-lock of the type mentioned can also be designed as a so-called frame lock, in which a swivel bracket or swivel bracket engages between the spokes of one of the wheels of a bicycle. In another embodiment, such a U-lock is designed as a brake disk lock, which is used to secure, for example, a motorcycle or a scooter against unauthorized use. The US 2015/137975 A1 describes an electronic padlock according to the preamble of claim 1. Another electronic padlock is from the GB 2,533,964 A known.

Such a U-lock is used, for example, to secure a two-wheeler on a bicycle stand or lamp post, or to secure a two-wheeler against unauthorized driving away. When the striker is unlocked, the striker can be brought into an open position in which the striker is released with one end or completely from the lock body in order to form an open loop. Starting from the open position, the striker can, for example be guided around a frame section of the two-wheeler and a bicycle stand, lamp post or the like, or the striker is only guided by a movable part (eg rim, brake disc) of the two-wheeler. The striker can then be (completely) closed and locked to the lock body in order to close the loop and thus secure the two-wheeler against unauthorized removal or unauthorized driving away.

The U-lock can be equipped with an electrical unit for an extended range of functions. Such an electrical unit can comprise various electrical, electronic, optoelectronic, electromechanical and / or electromagnetic components. The electrical unit can, for example, comprise an electronic alarm device which emits an acoustic and / or optical alarm signal as soon as an attempt at manipulation is detected, for example due to a detected change in position. Alternatively or additionally, the electrical unit can comprise a drive device which drives the locking mechanism of the U-lock electromechanically. Alternatively or additionally, the electrical unit can comprise a radio communication device with which radio signals can be transmitted and / or radio signals can be received. Furthermore, the electrical unit can comprise an electronic control circuit for the functions mentioned.

A problem for U-locks of this type are vibrations, as can occur, for example, when driving a two-wheeler. The vibrations can be transmitted to the components of the electrical unit or lead to relative movements of the components of the electrical unit, which can impair the functionality of the U-lock or even lead to a complete malfunction. Another problem is the space required in the lock body for fastening the components, which increases the size of the lock body. In addition, the Fastening the individual components of the electrical unit requires considerable assembly effort, which increases the manufacturing costs for such U-locks.

It is therefore the object of the invention to create an electronic U-lock for a two-wheeler in which the electrical components are protected against vibrations and which is characterized by a compact design and simple manufacture.

The object is achieved by an electronic U-lock according to claim 1, and in particular in that the molded part is designed to be elastic.

The term "molded part" refers here to a component which is preformed and dimensionally stable. Furthermore, the term "elastic" is synonymous with "resiliently flexible" or "flexible, but with the formation of resetting forces". Finally, the term “positive connection” relates to a connection between two connection partners in which the shape of one connection partner is complementary to the shape of the other connection partner in an area of mutual contact. In particular, it can be provided here that the two connection partners are connected to one another without play or essentially without play along a reference plane.

Some or all of the components of the electrical unit can therefore be positively received in a respective receptacle of the elastic molded part, which in turn is positively inserted into a housing of the U-lock (in particular in an inner housing of the lock body) ) be arranged in a predetermined relative position to one another in the housing.

The elastic molded part causes vibration damping of the components of the electrical unit relative to the housing and relative to each other, and thus offers protection against vibrations, for example against shocks that can be transmitted from the outside to the U-lock that is transported while riding the two-wheeler or due to manipulation attempts . If the U-lock, as explained below, has an electrical drive for the locking mechanism, the elastic molded part can also dampen the vibrations or noises caused by the drive and serve to protect neighboring components of the electrical unit, for example an electronic control circuit. In addition, the elastic molded part can seal the electrical unit against the ingress of moisture from outside the housing and thus effect or support efficient moisture protection.

Since the elastic molded part and the components of the electrical unit enter into a form-fitting connection, fewer individual fastening elements are required to fasten the components in the housing of the lock body. In particular, the number of screw connections required can be reduced or the use of screw connections for fastening the components of the electrical unit in the housing can be completely dispensed with. As a result, the space required for mounting the electrical unit can be reduced, which enables the U-lock to be designed in a more compact manner. At the same time, the assembly effort can be reduced, as a result of which the U-lock according to the invention can be manufactured more cost-effectively.

To achieve these advantages, it is not absolutely necessary for all components of the electrical unit to be held exclusively by the elastic molded part. In particular, individual components of the electrical unit can partially or be fastened exclusively to the housing of the lock body, for example to fastening pins provided there.

Preferred embodiments can be found in the dependent claims and the description.

According to one embodiment, the plurality of components of the electrical unit are electrically connected to one another. In particular, the components can be connected to one another in such a way that they can be used together as an assembly and / or in essentially one operation in the multiple receptacles of the elastic molded part in a form-fitting manner. This simplifies and facilitates the manufacturing process, since it allows the electrical unit to be prefabricated as a separate structural unit and its functionality to be checked. In particular, the components are thus already electrically connected before they are inserted into the elastic molded part, as a result of which a complex and cost-intensive formation of electrical connections between components already located in the receptacles of the molded part is avoided. Since the components are mechanically connected to one another, they can easily be inserted as an assembly into the elastic molded part and, if necessary, aligned with one another.

According to one embodiment, the multiple components of the electrical unit can be connected to one another by means of flexible electrical conductors. For example, the flexible electrical conductors can be designed as a flexible conductor track or be formed by cables. The flexible design increases the resistance to breakage of the electrical connection and thus also the service life of the electrical unit. In addition, a flexible configuration of the electrical conductors also offers advantages when assembling the electrical unit during the manufacturing process of the electronic U-lock.

• eine elektrische Antriebseinrichtung, die dazu ausgebildet ist, den Verriegelungsmechanismus des Bügelschlosses anzutreiben;
• eine Funkkommunikationseinrichtung; und/oder
• eine elektrische Energiequelle.

According to one embodiment, the electrical unit of the U-lock comprises at least one of the following devices:

• an electronic alarm device which is designed to detect a manipulation attempt and to output an acoustic and / or visual alarm signal;
• an electric drive device which is designed to drive the locking mechanism of the U-lock;
• a radio communication device; and or
• a source of electrical energy.

The electronic alarm device can for example have a sensor, an acoustic and / or optical alarm signal output device and a control circuit. The sensor can be designed, for example, as an acceleration sensor which detects a static acceleration (gravitation) and / or a dynamic acceleration in order to detect a change in position. When the electronic alarm device is activated, the control circuit can evaluate the signal from the sensor and trigger the output of an alarm signal in the event of unauthorized removal or movement of the two-wheeler (to which the padlock is attached).

According to one embodiment, the electric drive device has an electric motor and a control circuit. The electric motor can in particular be formed by a geared motor which has an electric motor with a reduction gear attached to it. As an alternative to an electric motor, an electromagnet can also be provided. An output of the electric drive device can drive the locking mechanism of the U-lock (for example one locking element or several locking elements) directly or by means of a transmission mechanism. In this way, the locking mechanism can be driven electrically in only one direction (eg unlocking direction), for example when the bolt is spring-loaded in the opposite direction is; or the locking mechanism can be driven in two mutually opposite directions by means of the electric drive device. When there is a corresponding request, for example due to a command received from a remote control unit or due to an actuation of a switch on the lock body, the electric motor or electromagnet is controlled by the control circuit connected to it.

According to one embodiment, the radio communication device of the electrical unit has a radio transmitter and / or a radio receiver and a control circuit. The radio transmitter can, for example, be designed to communicate with an assigned remote control unit, in particular according to Bluetooth, NFC or proprietary protocol. It is also conceivable that the radio transmitter is designed for communication with a public mobile radio network, in particular GPRS, UMTS, HSDPA or LTE, for example to forward a position signal or an alarm signal. The radio receiver can advantageously be designed to communicate in a corresponding manner with an assigned remote control unit and / or with a public mobile radio network. Alternatively or additionally, the radio receiver can be designed to receive position signals from a satellite-supported position detection system, in particular GPS or Galileo.

According to one embodiment, the electrical energy source of the electrical unit has a battery or an electrical accumulator (e.g. lithium-ion accumulator or electrochemical capacitor).

According to one embodiment, the multiple components of the electrical unit are held in the elastic molded part solely by a form fit and without further fastening elements, in particular without the use of screws. The multiple components are therefore only inserted into the receptacles of the elastic molded part and do not have to be replaced by additional fastening means how, for example, screw connections are connected to the elastic molded part. This reduces the assembly effort and the cost of manufacturing the electronic U-lock.

According to one embodiment, at least one (in particular some or all) of the plurality of components of the electrical unit is held in the respective receptacle of the elastic molded part by frictional connection. In particular, by inserting the respective component into the assigned receptacle, the elastic molded part can be stretched slightly apart (e.g. border of a recess) or compressed (e.g. fastening pin), so that the restoring forces of the elastic molded part thus generated support a reliable seating of the component in the receptacle.

According to one embodiment, at least one (in particular some or all) of the plurality of receptacles in the elastic molded part is formed by a respective depression in the elastic molded part. As a result, the respective component of the electrical unit can be particularly well supported flat in several directions and reliably held in the elastic molded part. In addition to the shape of the respective depression, the height of the respective depression can advantageously also be adapted to the corresponding thickness of the respective component.

In particular, the depressions can be designed in such a way that they at least essentially completely accommodate the components of the electrical unit, apart from their respective upper side. After the respective component has been inserted into the elastic molded part, in such an embodiment the elastic molded part thus surrounds the component and also covers an underside of the component facing the elastic molded part. Only an upper side of the respective component facing away from the elastic molded part is not in contact with the molded part.

According to one embodiment, at least one (in particular some or all) of the multiple receptacles of the elastic molded part is designed to encompass the respective component of the electrical unit along a closed circumference of the respective component. In this way, a particularly stable fit of the respective component of the electrical unit within the associated receptacle of the elastic molded part can be achieved. It can be provided here that the receptacle engages around the respective component in a force-locking manner along the closed circumference.

According to one embodiment, the elastic molded part can extend essentially along a main extension plane, at least one of the multiple receptacles of the elastic molded part forming a retaining collar into which one of the components of the electrical unit is inserted along an insertion direction that is parallel to the main extension plane of the elastic molded part runs, the retaining collar surrounding the component with respect to the direction of insertion (and in particular being able to hold it in a non-positive manner). In contrast to the recess mentioned, such a retaining collar can enable a component of the electrical unit to be inserted from the side. This proves to be advantageous, for example, with elongated components (e.g. electric motors), since these can then be accommodated in the molded part in a flat arrangement. Said retaining collar can be completely open along the insertion direction; Alternatively, the retaining collar can be closed at one end (e.g. floor, crossbar).

According to one embodiment, at least one of the multiple receptacles of the elastic molded part has a fastening pin on which one of the multiple components of the electrical unit is placed. Thus, a reliable fit of the component on the elastic molded part can also be brought about by this be that one or more elastic fastening pins engage in a respective opening of the component.

According to one embodiment, the elastic molded part can extend essentially along a main extension plane (in particular the aforementioned main extension plane), wherein the elastic molded part can be structured three-dimensionally with respect to the main extension plane. In other words, the elastic molded part can form a structure relative to a base plane (main plane of extent).

According to one embodiment, the elastic molded part is integrally formed by a single component. As a result, the elastic molded part can be produced quickly and inexpensively, for example as a cast part or injection molded part using a hollow mold or by means of a 3D printing technique. The cohesive design also increases the stability of the elastic molded part.

An advantageous embodiment results from the formation of the elastic molded part from an elastomer. Elastomers can be produced inexpensively, are available in many different variants and can be easily adapted to various requirements with regard to shape, size and specific design of the elastic molded part. The elastic molded part is preferably formed from a silicone.

According to one embodiment, the housing of the lock body (in particular an inner housing of the lock body) can have two housing parts, between which the elastic molded part is caught. As a result, the elastic molded part and the components of the electrical unit received therein can be reliably secured in the housing. In particular, this can prevent the components from being accidentally removed from the recordings of the elastic molding fall out. The two housing parts can be fastened to one another, for example, by screw and / or latching connections.

One embodiment of the invention provides that the housing of the lock body has two identical housing parts which are fastened to one another. In other words, the housing can be formed from two identical parts which are connected to one another by means of suitable connecting elements. This enables a cost-effective production, since it allows the expenditure for the production of the housing parts, for example by means of injection molding, to be reduced.

According to one embodiment, the elastic molded part can have at least one (in particular several) edge region (s) which is held in a force-locking manner between a respective shoulder of the two housing parts. As a result, the respective edge area along a circumferential section of the housing can act as a seal against undesired entry of moisture into the housing. The respective edge area of the elastic molded part can be formed, for example, by a tab section molded onto the outer circumference.

The housing of the lock body preferably has at least one ventilation opening which is closed by a vapor-permeable membrane. The ventilation opening allows moisture to escape from the housing, which can arise, for example, when the ambient temperature changes due to condensation inside the housing and can lead to a malfunction of the electrical or electronic components. The vapor-permeable membrane can for example be formed from a fabric material through which any moisture that may be present can diffuse out. The vapor-permeable membrane can be designed to at least largely prevent the entry of liquid (in particular water in the liquid aggregate state) through the vent opening into the housing. The vapor-permeable membrane can, for example, be on an inside or outside of the housing are glued in such a way that the vapor-permeable membrane surrounds the relevant vent opening circumferentially.

According to one embodiment, said housing is an inner housing that is received in an outer housing of the lock body. The outer housing of the lock body offers additional protection against vibration, impact and / or moisture and, in addition to the inner housing with the electrical unit, can enclose further components of the electronic U-lock, such as the locking mechanism of the lock body.

According to one embodiment, the striker is U-shaped and can be completely detached from the lock body in the open position. In the open position, the striker can thus be removed from the lock body, which can facilitate the handling of the electronic U-lock, in particular if the striker is to be guided around a frame section of the two-wheeler and another object (e.g. bicycle stand, lamp post or the like). The electronic padlock of this embodiment is advantageously designed such that both ends of the U-shaped striker in the lock body can be locked in the closed position by means of the locking mechanism.

According to a further embodiment, the U-lock is a portable lock that is easy to transport and can be used mobile or universally (in particular also for other two-wheelers of the user).

• eine elektrische Antriebseinrichtung, die dazu ausgebildet ist, den Verriegelungsmechanismus des Bügelschlosses anzutreiben;
• eine Funkkommunikationseinrichtung; und/oder

The invention relates, independently of the feature of an elastic molded part, to an electronic U-lock for a two-wheeler, with a lock body and a striker that is movable relative to the lock body between a closed position and an open position, the lock body a housing, a locking mechanism by means of which the striker can be locked in the closed position on the lock body, and an electrical unit, the housing of the lock body having at least one ventilation opening which is closed by a vapor-permeable membrane. The electrical unit can be accommodated in the housing and, for example, have at least one of the following devices:

• an electronic alarm device which is designed to detect a manipulation attempt and to output an acoustic and / or visual alarm signal;
• an electric drive device which is designed to drive the locking mechanism of the U-lock;
• a radio communication device; and or
• a source of electrical energy.

As explained above, moisture can escape from the housing through the vent opening, which can arise, for example, when the ambient temperature changes due to condensation within the housing and can lead to a malfunction of the electrical or electronic components of the electrical unit. The vapor-permeable membrane can for example be formed from a fabric material through which any moisture that may be present can diffuse out. The vapor-permeable membrane can be designed to at least largely prevent the entry of liquid (in particular water in the liquid aggregate state) through the vent opening into the housing. The vapor-permeable membrane can, for example, be glued onto an inside or outside of the housing in such a way that the vapor-permeable membrane circumferentially surrounds the vent opening in question.

Fig. 1 and 2 each show a perspective view of an embodiment of an electronic U-lock 10 according to the invention. The U-lock 10 comprises a lock body 12 and a striker 14. In the exemplary embodiment shown here, the striker 14 is U-shaped and has a first end 14a and a second end 14b which are inserted into locking openings 16 of the lock body 12. The lock body 12 comprises an outer housing 18 (in the illustration according to FIG Fig. 2 removed), a locking mechanism 20 and an inner housing 22. The locking mechanism 20 and the inner housing 22 are arranged inside the outer housing 18 and are protected against damage by this. The outer housing 18 is made of metal and can additionally be surrounded by a plastic casing (not shown).

Fig. 1 and 2 show the striker 14 in the closed position in which the first end 14a and the second end 14b of the striker 14 are locked in the lock body 12 by the locking mechanism 20.

Fig. 3 and Fig. 4 show exploded views of the structure of the inner housing 22 in a front view and a rear view. The inner housing 22 is made up of two housing components, namely a first housing part 24 and a second housing part 26. The first and second housing parts 24, 26 are two identical parts, ie they are at least substantially identical in shape. The first and second housing parts 24, 26 have round recesses 28 at corresponding positions, through which fastening elements (not shown), such as screws, are passed, which fasten the first and second housing parts 24, 26 to one another and thereby an interior space of the inner housing 22 define, which is delimited by the inner sides of the housing parts 24, 26. Here, the two components of the inner housing 22 can be made of die-cast zinc or plastic and, for example, can be manufactured using an injection molding process.

A vent opening 30 is formed on at least one of the housing parts, in the example shown on both housing parts 24, 26, which enables air to be exchanged between the interior of the inner housing 22 and an outside of the inner housing 22. The ventilation opening 30 is covered by a vapor-permeable membrane 31 made of a fabric. The membrane 31 can, for example, be glued onto the outside of the respective housing part 24, 26 or fastened to the housing part 24, 26 in some other way in order to close the ventilation opening 30 in a vapor-permeable manner. Through the vent 30 moisture can thus escape from the inner housing 22, which moisture can arise, for example, in the event of a change in the ambient temperature due to condensation within the inner housing 22. It is generally sufficient if only one ventilation opening 30 is provided with such a membrane 31; on the other housing part 24 or 26, the relevant opening can also be completely closed.

In Fig. 3 and Fig. 4 an elastic molded part 32 is also shown, which is inserted into the interior of the inner housing 22. Show here Fig. 3 the front 34 and Fig. 4 the rear side 36 of the elastic molded part 32. The elastic molded part 32 is integrally formed with a material fit and can be made of silicone, for example. The elastic molded part 32 is positively inserted into one of the housing parts, in the example shown in the first housing part 24, in such a way that the rear side of the elastic molded part 32 is in flat contact with a planar inner side of the first housing part 24 and the elastic molded part 32 is encompassed circumferentially by a border 27 of the first housing part 24. Here, flat edge regions 37 of the elastic molded part 32 lie within the border 27 on a respective shoulder 29 of the first housing part 24.

To further fix the elastic molded part 32 relative to the first housing part 24, the elastic molded part 32 has a plurality of openings 38. The first housing part 24 has a corresponding number of fastening pins 40 which are formed on the inside of the first housing part 24 at positions corresponding to the openings 38. When the elastic molded part 32 is inserted into the first housing part 24, the fastening pins 40 engage in the openings 38 and thereby cause additional centering and positional fixing of the elastic molded part 32.

An electrical unit 44 is in FIGS. 6 and 7 shown obliquely from the front above or obliquely from the rear below. The electrical unit 44 comprises an electronic alarm device with a loudspeaker 46 as well as a sensor, a radio communication device and a control circuit, which are arranged on a control circuit board 48. Furthermore, the electrical unit 44 comprises an electrical drive device which has a gear motor 50 with a downstream potentiometer 52, the rotatable part of which is positively plugged onto an output element 54 of the gear motor 50 (gear output shaft with flat). On the output element 54, above the potentiometer 52, there is also an eccentric 55 which drives the locking mechanism 20 of the electronic U-lock 10. The geared motor 50 comprises an electric motor and a reduction gear that translates the rotational movement of a rotor of the electric motor into slow speed. The potentiometer 52 enables position detection and regulation.

The components 46, 48, 50 of the electrical unit 44 are electrically conductively and mechanically connected to one another via flexible conductor tracks 56. The conductor tracks 56 of the electrical unit 44 give the electrical unit 44 structural stability, as a result of which the components 46, 48, 50 form a common assembly that can be handled as a single component in the further assembly process.

As in Fig. 3 and Fig. 5 As shown, the front side of the elastic molded part 32 has a plurality of receptacles 66, 68, 70 which are designed as depressions in the elastic molded part 32. The shape of the respective receptacle 66, 68, 70 corresponds to the shape of an associated component 46, 48, 50 of the electrical unit 44. The loudspeaker 46 is positively inserted into the receptacle 66 in such a way that its rear side and its periphery are covered by the elastic molded part 32 are enclosed. Here, by a certain undersize of the clear diameter of the essentially cylindrical receptacle 66 relative to the outer diameter of the loudspeaker 46 can be achieved that the loudspeaker 46 is also held in the receptacle 66 with a force fit. The control board 48 is inserted into the receptacle 68 in a form-fitting manner in such a way that the control board 48 is circumferentially enclosed by the elastic molded part 32, a non-positive fit being possible here as well. The geared motor 50 is inserted into the receptacle 70 in a form-fitting manner in such a way that it is circumferentially enclosed by a retaining collar 72 of the elastic molded part 32 and held in a force-fitting manner. The retaining collar 72 is formed projecting frontally on the elastic molded part 32. The retaining collar 72 defines an insertion direction for the geared motor 50 which runs parallel to a main extension plane of the elastic molded part 32.

In order to secure the components 46, 48 of the electrical unit 44 against falling out of the receptacles 66, 68 of the elastic molded part 32, a plurality of fastening pins 60 are provided between the electrical unit 44 and the inside of the second housing part 26. The fastening pins 60 are arranged and dimensioned in such a way that, when the housing parts 24, 26 are fastened to one another, the loudspeaker 46 is held in the receptacle 66 and the control circuit board 48 is held in the receptacle 68. Deviating from the representation according to Fig. 6 For example, the fastening pins 60 can be fastened to the inside of the second housing part 26.

The elastic molded part 32 thus dampens the vibrations of the components 46, 48, 50 of the electrical unit 44 and offers protection against vibrations against shocks that are transmitted from the outside to the inner housing 22, as well as against vibrations that may be generated by the geared motor 50.

In addition, the elastic molded part 32 helps to seal the electrical unit 44 against the ingress of moisture from the outside. For this purpose, it is provided that several edge regions 37 of the elastic molded part 32 are along of the circumference of the elastic molded part 32 between a respective shoulder 29 of the first housing part 24 and a respective shoulder 29 of the second housing part 26 is held in a non-positive and thus sealing manner. It goes without saying that such a circumferential seal between the two housing parts 24, 26 can be interrupted at least at the points at which passages for electrical connections are provided.

The assembly of the in FIGS. 3 to 7 The inner housing 22 of the electronic U-lock 10 according to the invention shown is carried out in a simple manner and requires only a few work steps, for example as follows, with deviations from the following sequence being possible:

1. (1) Initially, the potentiometer 52 is not yet attached to the output element 54 on the top of the geared motor 50, but is loosely connected via the flexible conductor tracks 56 to the underside of the geared motor 50 on the one hand and to the loudspeaker 46 on the other. The geared motor 50 with the laterally protruding potentiometer 52 is now with the output element 54 ahead from below (with respect to the representation according to FIG Fig. 3 and 5 ) is introduced into the receptacle 70 or the retaining collar 72 of the elastic molded part 32, the introduction not yet being completely complete.
2. (2) The potentiometer 52 is now inserted into the elastic molded part 32.
3. (3) The geared motor 50 is then inserted completely, and with its output element 54 through the potentiometer 52, into the retaining collar of the elastic molded part 32. The control board 48 and the loudspeaker 46 are now still loosely attached to the flexible conductor tracks 56.
