Description

Technical Field

[0001] The present disclosure generally relates to actuating devices. In particular, an actuating device for a locking device and a locking device including the actuating device are provided. Background Art

[0002] Some electromechanical lock cylinders include a core housing, a locking member rotatably arranged in the core housing, a rotatable knob, and an electromechanical coupling device for selectively coupling the knob to the locking member. When the user is authorized, the coupling device couples the knob to the locking member, and the lock can be opened by manually rotating the knob.

[0003] Some of these lock cylinders include a battery for powering the coupling and electronics housed in the knob, such as the credential evaluation electronics. The battery and electronics are typically housed in a rotatable knob to prevent cables from becoming tangled or disconnected. When the knob is rotated, the battery, electronics, and coupling rotate. This results in the product relying on the coupling housing to absorb most of the force during use. Furthermore, if the knob is broken by a criminal in a so-called brute-force attack, the electronics inside the knob could be exposed due to unauthorized tampering.

[0004] DE 102014105432 A1 discloses an electromechanical lock cylinder comprising a cylinder housing, a rotary knob, a clutch and an electric motor serving as a generator. Summary of the Invention

[0005] An object of the present disclosure is to provide an actuating device for a locking device which is safe.

[0006] Another object of the present disclosure is to provide an actuating device for a locking device that has a less complicated design and / or operation.

[0007] Yet another object of the present disclosure is to provide an actuating device for a locking device, which actuating device has a reliable design and / or operation.

[0008] It is a further object of the present disclosure to provide an actuating device for a locking device which has a cost-effective design and / or operation.

[0009] Yet another object of the present disclosure is to provide an actuating device for a locking device, which actuating device solves several or all of the aforementioned objects in combination.

[0010] Yet another object of the present disclosure is to provide a locking device comprising an actuating device, which solves one, several or all of the aforementioned objects.

[0011] According to one aspect, an actuating device for a locking device is provided, the actuating device comprising: a fixed structure; an actuating element capable of rotating relative to the fixed structure; an electric power source; a main shaft arranged to rotate by rotation of the actuating element; a locking member capable of moving between a locked position and an unlocked position; an electromechanical transmission device arranged in the main shaft, the transmission device being configured to adopt a locked state and an unlocked state, in which, in the locked state, the locking member cannot be moved from the locked position to the unlocked position by rotation of the actuating element, and in the unlocked state, the locking member can be moved from the locked position to the unlocked position by rotation of the actuating element; a receiver device fixed relative to the main shaft, the receiver device being electrically connected to the transmission device; and a transmitter device fixed relative to the fixed structure and arranged to be powered by the electric power source, the transmitter device being configured to wirelessly transmit power to the receiver device.

[0012] Thus, the fixed transmitter device is arranged to wirelessly transfer power to the rotatable receiver device.In addition, since the main shaft is arranged to be rotated by rotation of the actuating element, mechanical energy can be transferred from the actuating element to the main shaft by manual rotation of the actuating element.

[0013] By arranging the transmission device in the spindle, unauthorized access to the transmission device becomes more difficult. As a result, the actuation device becomes more secure.

[0014] The actuating element may be rotatable about an actuating axis.The actuating element may be a knob.

[0015] The main shaft may be arranged to rotate co-rotatingly with the actuating element. Alternatively or additionally, the main shaft may be arranged to rotate about an actuation axis. Alternatively or additionally, the actuating device may further include a transmission arranged to transmit rotation of the actuating element to rotation of the main shaft. The transmission may include a gear train. The main shaft may include a plug.

[0016] The power source may be fixed relative to the fixed structure. A cable may be provided between the power source and the transmitter device. The locking member may be rotatable between a locked position and an unlocked position.

[0017] The transmission device may be completely arranged within the fixed structure. Alternatively or additionally, the transmission device may be fixed to the main shaft. In this way, the transmission device rotates together with the main shaft.

[0018] The transmission device may include a coupling device configured to couple the spindle to the locking member when in the locked state and to decouple the spindle from the locking member when in the unlocked state. In this case, the spindle and the locking member can rotate together when the coupling device is in the locked state. When the coupling device is in the unlocked state, the actuating element can rotate, but this rotation is not transmitted to any movement of the locking member.

[0019] Alternatively, the transmission device may include a blocking device configured to block rotation of the spindle when in the locked state and to not block rotation of the spindle when in the unlocked state. In this case, the spindle and the locking member may be fixedly connected or integrally formed. When the blocking device is in the locked state, the actuating element cannot rotate. When the blocking device is in the unlocked state, rotation of the actuating element is transmitted to the joint rotation of the spindle and the locking member.

[0020] The power source may include an electromagnetic generator arranged to be driven by rotation of the actuating element to generate electrical energy. The actuating device including the generator is an energy harvesting actuating device. The generator may include a stator and a rotor, wherein the rotor is arranged to be rotationally driven relative to the stator by rotation of the actuating element to generate electrical energy.

[0021] The actuation device may, for example, include power management electronics configured to manage energy harvesting and control the supply of power to the transfer device. To this end, the power management electronics may include energy harvesting electronics, such as diodes for rectifying the voltage from the power generator, and passive, non-chemical electrical energy storage devices, such as capacitors. Thus, electrical energy can be harvested by rotating the actuation element in either direction about the actuation axis. The electrical energy storage device may or may not include a battery.

[0022] The energy storage device can be fixed relative to a fixed structure, i.e., located "externally." Alternatively, the energy storage device can be fixed relative to the main shaft, i.e., located "internally." In the former case, the collected energy can initially be stored in the energy storage device before being transferred from the transmitter device to the receiver device. In the latter case, the collected energy can be transferred directly from the transmitter device to the receiver device and then stored in the energy storage device located "internally."

[0023] Alternatively or additionally, the source of electrical power may comprise batteries rather than a generator.

[0024] The transmitter device may be configured to inductively transmit power to the receiver device. The transmitter device may include an electromagnetic wave transmitting coil, and the receiver device may include an electromagnetic wave receiving coil. The electromagnetic wave transmitting coil and the electromagnetic wave receiving coil may be near field communication (NFC) transmitting coils. Each of the transmitter device and the receiver device may include a resonant capacitor. Power may be transferred from the transmitter device to the receiver device through magnetic field resonance between the electromagnetic wave transmitting coil and the electromagnetic wave receiving coil. The transmitter device may further include an amplifier unit having a switching circuit. The receiver device may further include a power receiving unit having a rectification circuit and a smoothing circuit. The electromagnetic wave transmitting coil and the electromagnetic wave receiving coil together form a transformer. Alternating current passing through the electromagnetic wave transmitting coil generates an oscillating magnetic field according to Ampere's law. The magnetic field passes through the electromagnetic wave receiving coil, where an alternating electromotive force (EMF) (voltage) is induced according to Faraday's law of induction, which generates an alternating current in the electromagnetic wave receiving coil.

[0025] The main shaft may be rotatable about a rotational axis. In this case, each of the transmitter and receiver devices may be approximately centered or centrally positioned relative to the rotational axis. In this manner, the transmitter and receiver devices are always coaxially arranged. Furthermore, the transmitter and receiver devices may be arranged at a fixed distance. In these manners, the efficiency of energy transfer between the transmitter and receiver devices can be maximized. The rotational axis may be concentric with the actuation axis.

[0026] The spindle can be arranged inside the fixed structure. In this way, the fixed structure protects the transmission device from unauthorized tampering in the event that the actuating element is removed during a brute force attack.

[0027] The actuator may also include a connecting member that functionally connects the actuating element to the spindle. In this case, the connecting member can be arranged to release when the actuating element is removed. Functionally connected means that the rotation of the actuating element is at least partially transmitted to the rotation of the spindle via the connecting member. If the actuator is subjected to a forceful attack that causes the actuating element to be removed, the release of the connecting member makes it difficult to rotate the spindle. Furthermore, once the connecting member is released, the force from the forceful attack is not transmitted to the transmission mechanism. In this way, the safety of the actuator is further improved.

[0028] The transmitter device may include a transmitter device opening, and the receiver device may include a receiver device opening. In this case, the connecting member may pass through the transmitter device opening and the receiver device opening.

[0029] The connecting member may be connected to the spindle by a form-locking mechanism. A first end of the connecting member may be connected to the spindle by a form-locking mechanism. A second end of the connecting member may be fixed to the actuating element, for example, integrally formed therewith. Alternatively, the second end of the connecting member may be fixed to a portion of a transmission of the actuating device.

[0030] The connecting member may comprise a polygonal cross-sectional profile and the main shaft may comprise an opening having a corresponding polygonal cross-sectional profile.An example of such a polygonal cross-sectional profile is a square shape.

[0031] The connecting member may be a rod. Alternatively or additionally, the connecting member may be made of metal.

[0032] The transmitter device can be configured to wirelessly transmit the signal to the receiver device. Alternatively or additionally, the receiver device can be configured to wirelessly transmit the signal to the transmitter device. In these ways, data can be wirelessly transmitted between the receiver device and the transmitter device.

[0033] The actuating device may further include credential evaluation electronics and credential reading electronics disposed in the spindle. In this case, the credential evaluation electronics may be configured to evaluate an access signal from the credential reading electronics and, upon approval of the access signal, to issue an authorization signal to the transfer device to adopt the unlocked state. The access signal may include credential data associated with the user.

[0034] The credential reading electronics may include a receiving unit, such as an antenna, for receiving an input signal, and a reading unit. The credential reading electronics may be configured to send an access signal to the credential evaluation electronics. The credential evaluation electronics may be configured to determine whether authorization should be granted based on the access signal. If access is granted, for example, upon presentation of a valid credential, the credential evaluation electronics may issue an authorization signal. If access is not granted, for example, upon presentation of an invalid credential or if no credential is presented, the credential evaluation electronics may not issue an authorization signal.

[0035] The power management electronics and the credential reading electronics can be arranged inside the actuating element, and the credential evaluation electronics can be arranged inside the spindle. The credential reading electronics can be arranged to communicate wirelessly with an external device, such as a mobile phone. Wireless communication can be performed, for example, via BLE (Bluetooth Low Energy) or RFID (Radio Frequency Identification). As an alternative to wireless communication, the user can enter a code into the credential reading electronics, for example, via a keyboard. If the authorization request is denied, the transmission device is not switched, i.e., it remains in the locked state.

[0036] By arranging the credential evaluation electronics in the spindle, unauthorized access to the credential evaluation electronics becomes more difficult. Consequently, the credential evaluation electronics are arranged deep inside the actuating device. Consequently, the actuating device becomes more secure.

[0037] The actuator may further include a feedback indicator. The actuator may be configured to provide a feedback indication to the user via the feedback indicator based on the evaluation result of the access signal. Examples of feedback indicators include a speaker for audible indication, a light source for visual indication, and a vibration device for tactile indication. The feedback indication may be of a first type when the access signal grants authorization, and of a second type different from the first type when the access signal denies authorization.

[0038] Where the actuation means comprises a feedback indicator, the receiver means may be configured to wirelessly transmit the feedback signal to the transmitter means.The feedback signal may be emitted by the credential evaluation electronics.

[0039] The credential reading electronics may be fixed relative to the fixed structure. In this case, the transmitter device may be configured to transmit the access signal wirelessly, such as inductively, to the receiver device. Alternatively, the credential reading electronics may be fixed relative to the main shaft, such as being arranged in the main shaft.

[0040] The power source may be fixed relative to the fixed structure.

[0041] According to another aspect, a locking device comprising an actuating device according to the present disclosure is provided. The locking device may further comprise a core housing. The locking member may be rotatably arranged within the core housing.

[0042] The locking device may further comprise a driver. In this case, movement of the locking member from the locked position to the unlocked position may cause the driver to move from the driver locked position to the driver unlocked position. Conversely, movement of the locking member from the unlocked position to the locked position may cause the driver to move from the driver unlocked position to the driver locked position.

[0052] Hereinafter, an actuating device for a locking device and a locking device comprising the actuating device will be described. The same or similar reference numerals will be used to denote the same or similar structural features.

[0053] Figure 1 A side view of a locking device 10 is schematically shown. The locking device 10 includes an actuating device 12. The locking device 10 of this particular example further includes a first core half 14, a second core half 16, and a driver 18. The first core half 14 and the second core half 16 form an example of a core housing. The driver 18 can actuate a bolt (not shown) of the locking device 10.

[0054] Figure 2 Schematically shown is an exploded perspective view of the actuating device 12. The actuating device 12 comprises a fixing structure 20, an actuating element 22, an electromagnetic generator 24, a spindle 26, a locking member 28 and an electromechanical coupling device 30. The actuating element 22 of the present example is a knob.

[0055] The generator 24 is an example of an electric power source according to the present disclosure. The coupling device 30 is an example of an electromechanical transmission device according to the present disclosure. The coupling device 30 of this example includes an actuator having an actuator pin (not shown).

[0056] The actuator device 12 further includes a transmitter device 32 and a receiver device 34. The transmitter device 32 includes a transmitter device opening 36. The receiver device 34 includes a receiver device opening 38.

[0057] The fixing structure 20 of this particular example includes a body 40 and a through hole 42. The through hole 42 extends through the body 40.

[0058] The actuator 12 of this specific example further includes a first gear 44 and a second gear 46. The first gear 44 meshes with the second gear 46. The first gear 44 includes a square through hole 48.

[0059] The actuator 12 of this particular example further comprises a credential reading electronic device 50 and a power management electronic device 52. The credential reading electronic device 50 comprises a receiving unit (not shown), such as an antenna, for receiving an input signal, and a reading unit (not shown). The credential reading electronic device 50 is arranged to wirelessly communicate with an external device, such as a mobile phone, for example, via BLE.

[0060] The actuator 12 further comprises a feedback indicator 54. The feedback indicator 54 is configured to provide feedback to the user. The feedback indicator 54 may be, for example, a speaker, a light source or a vibration device.

[0061] The actuating device 12 of this particular example also includes a connecting member 56. The connecting member 56 of this example is a rod formed integrally with the actuating element 22. The connecting member 56 protrudes distally from an end 58 of the actuating element 22 into the interior of the actuating element 22. As used herein, a distal direction is a direction away from the user (e.g., toward the locking member 28), and a proximal direction is a direction toward the user.

[0062] Figure 3 A perspective cross-sectional view of the actuator 12 is schematically shown, and Figure 4 A cross-sectional side view of the actuator 12 is schematically shown. Figure 3 and Figure 4 The main shaft 26 is arranged inside the body 40 of the fixed structure 20. The fixed structure 20 can be fixed to the lock housing (not shown) of the locking device 10 by bolts. The generator 24 is fixed to the fixed structure 20.

[0063] The connecting member 56 engages the first gear 44 and the main shaft 26. In addition, the connecting member 56 passes through the transmitter device opening 36 and the receiver device opening 38. The connecting member 56 of this example includes a square cross-sectional profile. The square cross-sectional profile of the connecting member 56 engages the square through-hole 48 of the first gear 44. The square cross-sectional profile of the connecting member 56 also engages the main shaft 26. To this end, the main shaft 26 includes a proximal opening that receives the end of the connecting member 56. The connecting member 56 engages the main shaft 26 via a form lock 60. Due to the form lock 60, the rotation of the connecting member 56 is transmitted to the rotation of the main shaft 26. However, the connecting member 56 can be retracted proximally away from the main shaft 26. One or more bearings (not shown) are provided between the fixed structure 20 and the actuating element 22.

[0064] The coupling device 30 is arranged in the spindle 26 and fixed to the spindle 26. Thus, the fixing structure 20 protects the coupling device 30 from unauthorized tampering. The spindle 26 is arranged to be rotated about the actuation axis 62 by manual rotation of the actuation element 22.

[0065] The locking member 28 comprises a recess 64 for receiving an actuator pin of the coupling device 30. The recess 64 faces in the proximal direction.

[0066] The locking member 28 is rotatable between a locked position 66 and an unlocked position. Figure 3 and Figure 4 , the locking member 28 is in the locked position 66. The locking member 28 is rotatably arranged in the core housing (see Figure 1 ).

[0067] The coupling device 30 is configured to adopt a locked state 68 and an unlocked state. Figure 3 and Figure 4 , the coupling device 30 is in the locked state 68. In the locked state 68 of the coupling device 30, the spindle 26 can be rotated by manual rotation of the actuating element 22, but the rotation of the spindle 26 is not transmitted to the rotation of the locking member 28 via the coupling device 30. In the unlocked state of the coupling device 30, the spindle 26 is coupled to the locking member 28 via the coupling device 30. Thus, the spindle 26 and the locking member 28 rotate together, and the locking member 28 can be rotated from the locked position 66 to the unlocked position by manual rotation of the actuating element 22. When the transmission means is constituted by the coupling device 30, the locked state 68 and the unlocked state thus consist of an uncoupled state and a coupled state, respectively.

[0068] The receiver device 34 is fixed to the main shaft 26. Therefore, the receiver device 34 and the main shaft 26 rotate together. The receiver device 34 is electrically connected to the coupling device 30. The transmitter device 32 is fixed to the fixed structure 20. The transmitter device 32 is powered by the generator 24.

[0069] In this particular example, rotation of the actuating element 22 about the actuating axis 62 causes the first gear 44 to rotate via the engagement between the connecting member 56 and the first gear 44. The rotation of the first gear 44 is transmitted to the rotation of the second gear 46 via the meshing engagement between the first gear 44 and the second gear 46. The rotation of the second gear 46 drives the rotor (not shown) relative to the stator (not shown) of the generator 24, thereby generating electrical energy. Thus, the generator 24 is arranged to be driven by manual rotation of the actuating element 22 to collect electrical energy.

[0070] Furthermore, in this particular example, rotation of the actuating element 22 about the actuation axis 62 causes the spindle 26 to rotate due to the engagement between the connecting member 56 and the spindle 26 via the form lock 60. This is one of many implementations in which the spindle 26 may be arranged to rotate by rotation of the actuating element 22. Thus, the connecting member 56 is functionally connected between the actuating element 22 and the spindle 26.

[0071] The power management electronics 52 are configured to manage energy harvesting and control the supply of power to the coupling device 30. To this end, the power management electronics 52 include energy harvesting electronics (not shown), such as diodes for rectifying the voltage from the generator 24, and passive, non-chemical electrical energy storage devices (not shown), such as capacitors. Thus, electrical energy can be harvested by rotating the actuating element 22 in either direction about the actuation axis 62. In this example, the power management electronics 52 are fixed relative to the fixed structure 20.

[0072] When the actuating element 22 is manually rotated relative to the fixed structure 20 about the actuation axis 62, the receiver device 34 rotates but the transmitter device 32 is fixed. The transmitter device 32 and the receiver device 34 are arranged at a fixed distance. The transmitter device 32 and the receiver device 34 are separated by an air gap 70.

[0073] Transmitter device 32 is configured to wirelessly and inductively transmit power and signals to receiver device 34. To this end, transmitter device 32 includes an electromagnetic wave transmitting coil, and receiver device 34 includes an electromagnetic wave receiving coil. Receiver device 34 is also configured to wirelessly and inductively transmit signals to transmitter device 32. The transmitting coil and the receiving coil are concentric with respect to the axis of rotation of spindle 26. In this non-limiting example, the axis of rotation of spindle 26 is concentric with actuation axis 62.

[0074] The actuating device 12 also includes credential evaluation electronics 72. These are arranged in the spindle 26. Unauthorized access to the credential evaluation electronics 72 is thus made more difficult. The credential reading electronics 50 are arranged "externally," i.e., fixed relative to the fixed structure 20. In this example, the power management electronics 52 and the credential reading electronics 50 are arranged inside the actuating element 22 but outside the spindle 26, while the credential evaluation electronics 72 are arranged inside the spindle 26.

[0075] The credential reading electronics 50 is configured to send an access signal 74 to the credential evaluation electronics 72. The access signal 74 includes credential data associated with the user. Figure 3 and Figure 4 As shown, access signal 74 is wirelessly transmitted from transmitter device 32 to receiver device 34. Credential evaluation electronics 72 is configured to evaluate access signal 74. In addition to authorization, credential evaluation electronics 72 can be configured to verify access signal 74, i.e., determine the authenticity of the user based on access signal 74.

[0076] If access is denied, that is, if the access signal 74 contains invalid credentials or no credentials, the credential evaluation electronics 72 sends a denied feedback signal to the feedback indicator 54. In response to the denied feedback signal, the feedback indicator 54 emits a denied feedback indication, such as a first type of sound. The denied feedback signal is wirelessly transmitted from the receiver device 34 to the transmitter device 32.

[0077] If access is granted, that is, if the access signal 74 includes valid credentials, the credential evaluation electronics 72 transmits an authorization signal 76 to the coupling device 30. In response to the authorization signal 76, the coupling device 30 moves from the locked state 68 to the unlocked state. Furthermore, the credential evaluation electronics 72 transmits a granted feedback signal to the feedback indicator 54. In response to the granted feedback signal, the feedback indicator 54 emits a granted feedback indication, such as a second type of sound different from the first type. The granted feedback signal is wirelessly transmitted from the receiver device 34 to the transmitter device 32.

[0078] Figure 5 Schematically shown is a cross-sectional side view of the actuating device 12 when the coupling device 30 has adopted the unlocked state 78. Figure 5, an actuator pin 80 of the coupling device 30 can be seen. In the unlocked state 78, the actuator pin 80 is driven to protrude to engage the recess 64 of the locking member 28. When the coupling device 30 has adopted the unlocked state 78, manual rotation of the actuating element 22 is transmitted to the rotation of the locking member 28 from the locked position 66 to the unlocked position. The rotation of the locking member 28 from the locked position 66 to the unlocked position causes the driver 18 to move from the driver locked position to the driver unlocked position to open the locking device 10.

[0079] In the event that the actuator device 12 is subjected to a forceful attack, for example, if the actuator element 22 is broken by a hammer, the removal of the actuator element 22 will cause the connecting member 56 to fall out of the form lock 60. In this way, the generation of electrical energy and the rotation of the spindle 26 are made difficult. In addition, even if the actuator element 22 is removed, the credential evaluation electronics 72 are not exposed.

[0080] Figure 6 A cross-sectional side view of another example of an actuator 12 is schematically shown. Figures 2 to 5 Instead of generator 24, Figure 6 The actuating device 12 in the embodiment includes a battery 82. Furthermore, the actuating device 12 includes a blocking device 84 instead of the coupling device 30. According to the present disclosure, the battery 82 and the blocking device 84 are another example of an electric power source and a transmission device, respectively.

[0081] exist Figure 6 In FIG, the locking member 28 is fixed to the spindle 26. The actuator pin 80 is arranged to selectively engage the recess 64 in the fixing structure 20. Figure 6 , the actuator pin 80 engages the recess 64 and the blocking device 84 thus adopts the locked state 68. When the blocking device 84 adopts the locked state 68, the spindle 26 cannot rotate. Therefore, the actuating element 22 cannot rotate either.

[0082] If access is granted, that is, if access signal 74 includes a valid credential, credential evaluation electronics 72 transmits an authorization signal 76 to blocking device 84. In response to authorization signal 76, blocking device 84 moves from locked state 68 to unlocked state 78. Furthermore, credential evaluation electronics 72 transmits a granted feedback signal to feedback indicator 54. In response to the granted feedback signal, feedback indicator 54 emits a granted feedback indication, such as an audible tone. The granted feedback signal is wirelessly transmitted from receiver device 34 to transmitter device 32.

[0083] Figure 7 The blocking device 84 is schematically shown in the unlocked state 78. Figure 6FIG. 7 is a cross-sectional side view of the actuator 12 in FIG. In the unlocked state 78, the actuator pin 80 is retracted from the recess 64, and thus the rotation of the spindle 26 is unblocked. The spindle 26 and the locking member 28 can thus be rotated together by manual rotation of the actuating element 22. When the transmission means is constituted by the blocking means 84, the locked state 68 and the unlocked state 78 thus constitute a blocked state and an unblocked state, respectively.

[0084] Figure 8 The locking member 28 is schematically shown in the unlocked position 86. Figure 6 and Figure 7 1. A cross-sectional side view of the actuator 12 in FIG.

[0085] Although the present disclosure has been described with reference to exemplary embodiments, it will be understood that the present invention is not limited to what has been described above. For example, it will be understood that the dimensions of the components may be varied as desired. Accordingly, this means that the present invention may be limited only by the scope of the claims appended hereto.
