Description

[0001] The invention relates to a mobile lock for securing a mobile object, wherein the lock can be wirelessly controlled by a mobile device, wherein the lock has a base body and a connecting body that can be locked to the base body, wherein the base body comprises: a housing, an electric motor, a processing unit for controlling the electric motor, wherein the processing unit is configured to control the electric motor depending on a signal received by a mobile device, an energy conversion unit for converting electromagnetic energy transmittable via a mobile device, in particular electromagnetic energy transmittable via NFC technology or QI technology, into an electrical voltage for supplying the electric motor and the processing unit, and a mechanical locking system comprising a locking unit that is displaceable with respect to the housing and at least one locking element coupled thereto.

[0002] Locks that can be activated by electromagnetic energy are known from the prior art. For example, there are locks that have a processing unit and a battery or accumulator to power the processing unit, and the lock can be locked and unlocked using an app, e.g., via a smartphone. The batteries must be replaced at certain intervals, or the accumulators must be recharged via cable at certain intervals. Such locks are also available as portable locks, for example, as bicycle locks. A disadvantage of such locks is that if the battery or accumulator is completely discharged, the lock can no longer be controlled because it lacks the necessary electrical energy.To avoid this problem, attempts have been made to increase energy efficiency and / or the amount of energy stored in the lock, thereby extending the time intervals until complete discharge. Additionally, early warning systems can be implemented that, for example, alert the user via an app when the lock's battery is low and suggest replacing or recharging the energy storage device.

[0003] One objective of the invention is therefore to create a lock that offers increased user-friendliness.

[0004] This problem is solved with a lock of the type mentioned at the outset, in which, according to the invention, the locking unit comprises the following: at least one locking bolt, a first force means for exerting a force, in particular a spring element, which acts on the at least one locking bolt and exerts a force on it, pressing the at least one locking bolt towards an end position, a cam disk rotatably connected to the electric motor, wherein the at least one locking bolt is mechanically coupled to the cam disk, so that by a rotational movement of the cam disk the at least one locking bolt can be moved away from the end position towards a release position against the force of the first force means, wherein in the release position of the at least one locking bolt the locking unit is displaceable with respect to the housing, namely from a closed position to an open position and vice versa.and wherein in the end position of the at least one locking bolt the locking unit is fixed in the closed position, and wherein the locking unit has a guide section which is in mechanical engagement with the locking element, such that in the closed position of the locking unit the at least one locking element is secured against displacement with respect to the housing, such that a connecting body mechanically coupled to the base body, in particular one pushed onto it, is closed to the base body and secured against opening by mechanical engagement of the at least one locking element in the connecting body, and in an open position of the locking unit the at least one locking element is displaceable with respect to the housing along the guide section, so that the mechanical engagement with the connecting body can be released.

[0005] This solution according to the invention creates a lock that can be controlled by an external device, such as a smartphone, and simultaneously supplied with electrical energy wirelessly. A cable connection for charging the lock and / or a battery compartment for replacing the energy storage device are therefore completely unnecessary. The energy can be transferred to the lock electromagnetically.

[0006] The force source can be implemented as a spring element, a magnet, or by other suitable means. The electric motor can be, but does not have to be, part of the locking unit. An embodiment is conceivable in which the motor is fixed to the housing and the locking unit moves without the motor as long as a rotary motion generated by the motor is transmitted to the cam. The mobile lock according to the invention can be used for a wide variety of applications where high mobility and wireless control are particularly advantageous. For example, it can be used to secure mobile objects such as bicycles, motorcycles, etc. The lock can therefore be used, for example, as a bicycle lock, a motorcycle lock, or even as a lock to secure mobile furniture.

[0007] In particular, it may be provided that a second force means is provided within the housing, which exerts a force on the locking unit that pushes the locking unit in the direction of the open position.

[0008] Furthermore, it may be provided that, in order to minimize the electrical energy consumption of the lock, the computing unit for controlling the electric motor is configured in such a way that the electric motor is controlled exclusively for moving at least one locking bolt from the end position to the release position, and wherein the second force means is dimensioned such that, by moving the locking bolt to the release position, the locking unit is pressed into the open position from the closed position solely by the force of the second force means.

[0009] In particular, the connecting body may be provided with a coupling section, especially in the form of a projection, which coupling section is designed to contact the locking unit when the connecting body is manually slid onto the base body and to move the locking unit from the open position to the closed position against the force of the second force means. This can be done, for example, by manual sliding by the user.

[0010] Furthermore, it may be provided that the electric motor is equipped with a gearbox which is self-locking.

[0011] In particular, the cam disc may be provided with at least one mechanical stop that limits the rotational movement required to move the at least one locking bolt from the end position to the release position. This establishes a defined position of the cam disc after the rotational movement has been completed.

[0012] Furthermore, it can be provided that the stop is designed in such a way that a rotational movement to be carried out is limited and at the same time, after the rotational movement has been completed, the transition of the at least one locking bolt from the release position to the end position is released by the cam disc, so that when the locking unit is in the closed position, the at least one locking bolt is pressed into the end position by means of the first force means.

[0013] In particular, it may be provided that the cam disc has four sections, each with a stop, which sections are offset from each other by 90° and are otherwise identical, so that a rotary movement to transfer the at least one locking bolt from the release position to the end position takes place over an angle range of 90°.

[0014] Furthermore, the lock may be designed to have exactly two locking bolts arranged opposite each other, with the first force being a compression spring positioned between these locking bolts, which pushes the locking bolts apart. The advantage of using two opposing locking bolts is that successful manipulation by striking the lock from the outside can be countered, since if one bolt is struck inwards, the other bolt is pushed even further outwards, thus blocking the lock.

[0015] In particular, the lock may be provided with three locking elements, each designed as a ball, wherein the housing is cylindrical in the area of ​​the locking elements and the balls are arranged on the circumference of the housing such that they are offset from each other by 120° along the circumference and are arranged within a common plane. This plane is oriented orthogonally to the longitudinal axis of a cylindrical extension of the housing in this area.

[0016] Furthermore, it can be provided that the guide section for guiding the at least one locking element is designed in the form of a cylindrical section extending along the locking unit such that, in the closed position of the locking unit, the at least one locking element is secured against displacement towards the center of the cylindrical section by bearing against its surface. The cylindrical section has a taper in a certain area, particularly in the form of a groove, arranged such that, in the open position of the locking unit, the at least one locking element can be moved towards the center of the cylindrical section, thus disengaging from the connecting body. The transition is preferably smooth, and in particular continuous.

[0017] In particular, the lock may also have a mechanically movable connection, especially in the form of a chain, which inseparably connects one end of the base body to one end of the connecting body, so that a closed loop is formed when the connecting body is closed with the base body. The term "inseparable" means that separation can only occur by destroying or damaging the component in question.

[0018] Furthermore, it can be provided that the computing unit is configured to receive the signal from the energy conversion unit and evaluate it after receipt, whereby, if it matches a predefinable reference signal, an opening process is triggered by waiting a period of time until a target amount of energy has been received by a mobile device via the energy conversion unit, wherein the opening process is triggered by the computing unit by controlling the electric motor to rotate the cam disc into the release position.

[0019] In particular, it can be provided that the electric motor and the locking unit are arranged in the housing, wherein the housing has a cylindrical opening in which the second force means followed by the electric motor and the locking unit is inserted, wherein the at least one locking element is also held between the housing and the locking unit.

[0020] Furthermore, it can be provided that the target energy quantity is chosen to be at least high enough to supply the electric motor 5 with sufficient energy to carry out the rotation of the cam disc into the release position, whereby the lock is preferably free of external charging connections.

[0021] The invention is explained in more detail below with reference to an exemplary and non-limiting embodiment, which is illustrated in the figures. These show Figure 1 a schematic representation of a lock according to the invention including the chain connected thereto, Figure 2 a representation of the castle according to Fig. 1 without an external casing and without a chain, Figure 3A another view of the castle in an open state, Figure 3B a sectional view of the castle according to section line AA from Fig. 3A , Figure 4A another view of the castle in a closed state, Figure 4B a sectional view of the castle according to section line AA from Fig. 4A , Figure 4C and 4D a process by which the lock is opened, Figure 5A a detailed view of the base body of the lock, showing a locking unit in a closed position, Figure 5B a detailed view of the base body of the lock, showing a locking unit in an open position, Figure 6 a detailed representation of components of the locking unit, Figure 7 an exploded view of components of the locking unit, Figure 8 another schematic exploded view of components of the locking unit, Figure 9A a detailed representation of a cam disc that can be used in the locking unit, specifically in a closed position, Figure 9B and 9C a rotational movement of this cam disc towards an open position, and Figure 9Da rotational movement of the cam disc until it reaches a stop.

[0022] In the following figures, unless otherwise stated, the same reference symbols denote the same features.

[0023] Fig. 1 Figure 1 shows a schematic representation of a mobile lock 1 according to the invention, including the chain 14 connected to it, which is indicated here only by individual chain links, but in practical use is of course designed as a single continuous strand. The chain 14 connects an end 3' of the base body 3 with an end 4' of the connecting body 4 in an inseparable manner, so that by closing the connecting body 4 with the base body 3 a (in Fig. 1 (not shown) a closed loop is formed.

[0024] The lock 1 can be wirelessly controlled by a mobile device 2. It comprises a base body 3 and a connecting body 4 that can be locked to the base body 3. The base body 3 has a housing 11, which is partially enclosed by an outer housing 16. In conjunction with Fig. 3B It should be noted that the base unit 3 also includes an electric motor 5, a processing unit 6 for controlling the electric motor 5, and an energy conversion unit 7 for converting electromagnetic energy transmitted via a mobile device 2. This energy can be transmitted, for example, via NFC or Qi technology. The energy conversion unit 7 converts this energy into an electrical voltage to supply the electric motor 5 and the processing unit 6. The electromagnetic energy emitted by the mobile device contains the subset or signal S in , which is received and converted by the energy conversion unit 7.

[0025] The processing unit 6 is configured to control the electric motor 5 depending on a signal S received by a mobile device 2. This means that this signal S can contain not only energy but also identification and / or control information, which can be used to configure the lock 1, identify the mobile device 2, and, if the identification is correct, control the electric motor 5 in such a way that the lock 1 is moved from a closed state to an open state.

[0026] The lock 1 also includes a mechanical locking system 8 (see Fig. 6 ). The locking system in turn comprises a locking unit 9 which is movable with respect to the housing 11 and at least one locking element 10 coupled thereto.

[0027] The locking unit 9 comprises the following: at least one locking bolt 9a, a first force means 9b (see Fig. 7 ) for exerting a force, in particular a spring element that acts on the at least one locking bolt 9a and exerts a force on it, which moves the at least one locking bolt 9a towards an end position 9aP1 (see e.g. Fig. 3B and 4B ) presses.

[0028] A cam disk 9c is designed to guide the bolts 9a and is rotatably connected to the electric motor 5. Figures 9A to 9D The figures clearly show that the locking bolt 9a is mechanically coupled to the cam disk 9c, such that a rotational movement of the cam disk 9c allows at least one locking bolt 9a to be moved away from the end position 9aP1 towards a release position 9aP2 against the force of the first force means 9b. This mechanical coupling is achieved via a pin 9a' of the respective locking bolt 9a, which is guided in a guide track 9c" of the cam disk 9c.

[0029] The cam disk 9c has at least one mechanical stop 9c' that limits the rotational movement required to move the at least one locking bolt 9a from the end position 9aP1 to the release position 9aP2. In this case, the stop 9c' can be designed such that it limits the rotational movement and, at the same time, after the rotational movement has ended, the cam disk 9c releases the transition of the at least one locking bolt 9a from the release position 9aP2 to the end position 9aP1, so that when the locking unit 9 is in the closed position 9aP1, the at least one locking bolt 9a is pressed into the end position 9aP1 by means of the first force 9b.

[0030] The cam disc 9c can have four sections, each with a stop 9c', which sections are offset from each other by 90° and are otherwise identical, so that a

[0031] A rotary movement is performed to move at least one locking bolt 9a from the release position 9aP2 to the end position 9aP1 over an angle range of 90°.

[0032] It can be provided that the lock 1 has exactly two locking bolts 9a, which are arranged opposite each other, and that the first force means 9b is designed in the form of a compression spring arranged between these locking bolts 9a, which pushes the locking bolts 9a apart. In this way, manipulation from the outside is made even more difficult.

[0033] With regard to Fig. 5B It should be mentioned that in the release position 9aP2 of at least one locking bolt 9a, the locking unit 9 is displaceable in relation to the housing 11, from a closed position 9P1 (see Fig. 5A) into an open position 9P2 and vice versa, and wherein in the end position 9aP1 of the at least one locking bolt 9a the locking unit 9 is fixed in the closed position 9P1.

[0034] This fixing is achieved by engaging a groove 11a, whereby one in Fig. 6 The spring 13 shown can be provided, which pushes the locking unit 9 towards the end of the groove 11a and thus firmly positions the locking unit 9. As soon as the locking bolts 9a retract by rotating the rotary disc 9c, the engagement of the bolts 9a in the groove 11a is released and the locking unit 9 can be moved into the open position 9P2 by means of the spring force of the spring 13.

[0035] The locking unit 9 has a guide section 12 along which locking elements 10, which are designed as balls in this case, are guided. The guide section 12 is designed as a cylindrical section extending along the locking unit 9 such that the at least one locking element 10 is secured against displacement towards the center of the cylindrical section in the closed position 9P1 of the locking unit 9 by bearing against the surface of the cylindrical section. The cylindrical section has a taper 12' in a region, in particular in the form of a groove, which is arranged such that in the open position 9P2 of the locking unit 9, the at least one locking element 10 is moved towards the center of the cylindrical section. In this way, engagement with a connecting body 4 pushed onto the base body 3 (see, for example, in [reference]) is prevented. Fig. 4Bin the closed position 9P1) can be released, since a corresponding engagement area 4b of the connecting body 4 is no longer blocked by the locking elements 10, but can now be released from the base section 3 by sliding along the base section. This process is shown in the figures. Fig. 4B to Fig. 4D shown.

[0036] The lock 1 may be provided to have three locking elements 10, each designed as a ball, wherein the housing 11 is cylindrical in the area of ​​the locking elements 10 and the balls are arranged on the circumference of the housing 11 such that they are offset from each other by 120° along the circumference and are arranged within a common plane. This plane may be oriented orthogonally to the longitudinal axis of a cylindrical extension of the housing in this area.

[0037] As already mentioned, the locking unit 9 has a guide section 12 which is in mechanical engagement with the locking element 10, such that in the closed position 9P1 of the locking unit 9, the at least one locking element 10 is secured against displacement with respect to the housing 11, so that a connecting body 4, which is mechanically coupled to the base body 3, in particular slid onto it, is closed to the base body 3 by the mechanical engagement of the at least one locking element 10 with the connecting body 4 and secured against opening. In an open position 9P2, however, the at least one locking element 10 is displaceable with respect to the housing 11 along the guide section 12 or can be moved into the groove 12', so that the mechanical engagement with the connecting body 4 can be released.

[0038] Figure 9Ashows a detailed representation of a cam disc 9c, which can be used in the locking unit 9, in a closed position 9P1, Figure 9B and 9C show a rotational movement of this cam disk 9c towards an open position 9P2 and Figure 9D shows a rotational movement of the cam disc 9c up to the stop 9c'.

[0039] In Fig. 6It is evident that the lock has a second force means 13, which is arranged within the housing 11, wherein the force means 13 exerts a force on the locking unit 9, which pushes the locking unit 9 towards the open position 9P2. To minimize the electrical energy consumption of the lock 1, the control unit 6 for controlling the electric motor is configured such that the electric motor 5 is controlled exclusively for moving the at least one locking bolt 9a from the end position 9aP1 to the release position 9aP2, and wherein the second force means 13 is dimensioned such that, by moving the locking bolt 9a to the release position 9aP2, the locking unit 9 is pushed from the closed position 9P1 to the open position 9P2 solely by the force of the second force means. With regard to Fig. 3B and 4BIt should be noted that the connecting body 4 has a coupling section 4a, in particular in the form of a projection 4a', which coupling section 4a is designed to contact the locking unit 9 when the connecting body 4 is manually slid onto the base body 3 and to move the locking unit from the open position 9P2 to the closed position 9P1 against the force of the second force means 13. This can be done, for example, by a user manually sliding the connecting body 4 onto the base body 3.

[0040] It may be provided that the electric motor 5 is equipped with a gearbox which is designed to be self-locking.

[0041] With regard to Fig. 5AIt should be noted that the processing unit 6 is configured to receive the signal S from the energy conversion unit 7 and evaluate it upon receipt. If the signal matches a predefined reference signal, an opening process is triggered by waiting a certain period of time until a target amount of energy has been received by a mobile device via the energy conversion unit 7. The opening process is then triggered by the processing unit 6 by controlling the electric motor 5 to rotate the cam 9c into the release position 9aP2. If, for example, a user has paired their smartphone with the lock 1, the identification of the smartphone in question can be used to unlock the lock 1.In the exemplary technical setup shown here, the bolts 9a would release the locking unit 9, which in turn causes the spring 13 to move the locking unit 9, thus releasing the locking element 10 and causing the front end of the locking unit 9 to abut the projection 4a' of the connecting body 4, at least partially pushing it off the base body 3. Opening is thus clearly identifiable for a user and can be reversed by manually sliding the connecting body 4 onto the base body 3 against the force of the spring 13, without consuming any electrical energy. Closing can be performed entirely manually and without establishing a connection to a mobile device 2.

[0042] The target energy quantity is chosen to be at least high enough to supply the electric motor 5 with sufficient energy to rotate the cam disc 9c into the release position 9aP2, with the lock 1 preferably being free of external charging connections.

[0043] In Fig. 3B and 4B It can be seen that the electric motor 5 and the locking unit 9 are arranged in the housing 11, the housing 11 having a cylindrical opening 11b. The second force means 13 (not shown) is contained therein, followed by the electric motor 5 and the locking unit 9, and the at least one locking element 10 is held between the housing 11 and the locking unit 9, so that the locking element 10 cannot detach from the base body 3 even when removed from the connecting body 4.

[0044] The invention is not limited to the embodiments shown, but is defined by the entire scope of protection of the claims. Individual aspects of the invention or the embodiments may also be adopted and combined. Any reference numerals in the claims are exemplary and serve only to improve the readability of the claims, without limiting them.
