Technical Field
The present disclosure relates generally to lock devices for electronic locking systems. Specifically provided are: a lock device for an electronic locking system, wherein the lock device comprises an energy harvesting device; an electronic locking system including the lock device; and a method for operating a lock device of an electronic locking system.
Background
Various types of electronic locking systems are known. Instead of utilizing a purely mechanical lock, some locking systems include an electronic driver of a lock member (e.g., a latch) to, for example, unlock the door for access to the rear area of the door.
Furthermore, instead of unlocking the door with a conventional key, various types of electronic communication methods are known for authorizing personnel to access the area behind the door. For example, a Radio Frequency Identification (RFID) system may be used, in which case a reader of the RFID system is mounted in a door and a tag is carried by or attached to an object to be identified.
In order to power electronic locking systems, so-called "self-powered" electronic locking systems have been proposed, in which electricity is generated by mechanical actuation of the door handle and used to power the electronic locking system. This concept is also referred to as energy harvesting.
US 2014/0225375 a1 discloses a power supply device for a door handle. The latch is moved by turning the door handle, the rotating shaft of which is driven to turn the driving gear. The rotation of the drive gear is transmitted as rotation of the generator shaft to generate power for the electronic lock.
Further, some locking assemblies include a latch shaft that is blocked by a blocking device. If the latch shaft can only assume two states, a blocking state or an unblocking state, the handle shaft cannot be used for energy harvesting when blocked. Such locking assemblies typically require an additional source of electrical power to operate the blocking device.

It is an object of the present disclosure to provide a lock device for an electronic locking system that is capable of energy harvesting when the lock device is locked.
A more specific object of the present disclosure is to provide a lock device for an electronic locking system that enables energy harvesting when a latch shaft is blocked or when the latch shaft is decoupled from a handle shaft.
It is another object of the present disclosure to provide a lock device for an electronic locking system that is capable of harvesting energy and rotating an output member with one single rotation of the input member, i.e., that provides seamless access.
It is a further object of the present disclosure to provide a lock device for an electronic locking system that has a simple (e.g., with few parts), compact, reliable, and/or inexpensive design.
It is a further object of the present disclosure to provide a lock device for an electronic locking system that has a low power consumption.

It is a further object of the present disclosure to provide a lock device for an electronic locking system that addresses some or all of the aforementioned objects.
It is a further object of the present disclosure to provide an electronic locking system including a lock device that addresses one, several, or all of the aforementioned objects.
It is a further object of the present disclosure to provide a method for operating a lock arrangement of an electronic locking system that addresses one, several or all of the aforementioned objects.
According to one aspect, there is provided a lock device for an electronic locking system, the lock device comprising: an input member arranged to rotate about an input rotation axis; an output member arranged to rotate about an output rotation axis; an energy harvesting device configured to generate electrical energy from rotation of the input member in a first direction about the input rotation axis; and selective transmission means movable between a locked state in which the output member is not rotatable about the output rotation axis by rotation of the input member about the input rotation axis and an unlocked state in which the output member is rotatable about the output rotation axis by rotation of the input member about the input rotation axis in a first direction; wherein the transfer device is powered by the energy harvesting device. Throughout the present disclosure, the locked state and the unlocked state of the transmission device may be constituted by the locked position and the unlocked position, respectively.
The lock device may be referred to as locked and unlocked, respectively, when the transfer device assumes the locked and unlocked states, respectively. Thus, the lock arrangement may be configured such that the input member may be rotated (e.g. rotated about the input rotation axis or continuously rotated, e.g. 45 ° to 135 °, such as 80 ° to I00 °, such as 90 °) when the transfer device assumes the locked state. In the locked state of the transmission device, the transmission device may, for example, block and/or decouple the output member from the input member. Conversely, in the unlocked state of the transmission, the transmission may, for example, unblock the output member and/or couple the output member to the input member. Throughout the present disclosure, the locked state of the transfer device may be referred to as a first position, and the unlocked state of the transfer device may be referred to as a second position.
With this lock arrangement, regardless of whether access is granted or not, the input member may be rotated about the input rotation axis while the transmission device is in the locked state and energy from this rotation may be collected, and the transmission device is subsequently moved to the unlocked state. The transmission device may be moved from the locked state to the unlocked state once sufficient energy for activating the transmission device has been generated by the energy harvesting device.
When the input member is rotated in a first direction about the input rotation axis by a first angular distance, the collected energy may be used to wake up the access control device, execute an access control program through the access control device, and move the delivery device from the locked state to the unlocked state (if access is granted) and then back to the locked state. If access is granted, the input member may be rotated about the input rotation axis a first direction followed by a first angular distance for a second angular distance to manipulate the output member, e.g. the latch shaft, to open the lock device. The rotation of the input member may be continuous through the first and second angular distances in the first direction about the input rotation axis. Thus, based on one single rotation of the input member, the lock device may perform the access control procedure using energy collected by the rotation, the transmission device may move from the locked state to the unlocked state using energy collected by the rotation, and the output member may be rotated, e.g. the latch shaft, from the locked state to the unlocked state. In other words, the same single movement can be used to generate energy and unlock the lock device. The energy collected by this same rotation can also be used to move the transmission from the unlocked state back to the locked state.
The transfer device may be powered directly by the energy harvesting device. Alternatively or additionally, the energy harvesting device may comprise an electrical power storage unit. In this case, the transfer device may be powered indirectly by the collecting device, for example via a power storage unit. Examples of power storage units according to the present disclosure are capacitors and supercapacitors.
The transfer device may be powered solely by the energy harvesting device. A lock device according to the present disclosure may alternatively be referred to as a lock assembly.
The input and output axes of rotation may be substantially concentric or concentric. Alternatively, the input and output axes of rotation may be offset relative to each other. Alternatively, the input and output axes of rotation may be angled with respect to each other.
According to one variant, the input member comprises an engagement structure; the output member comprises an engageable structure arranged to be engaged by the engagement structure; the transmission means is constituted by blocking means movable between a blocking state in which the blocking means blocks rotation of the output member about the output rotation axis and a release blocking state in which the output member is allowed to rotate about the output rotation axis; and the engagement structure is rotatable through an angular gap about the input rotation axis prior to engagement with the engageable structure. With this variation, energy harvesting can be performed while rotating the input member through the angular gap. Throughout the present disclosure, the blocking state and the unblocking state of the blocking device may be constituted by a blocking position and a unblocking position, respectively.
In this variant, the locked state of the transmission means is constituted by the blocked state of the blocking means, and the unlocked state of the transmission means is constituted by the unblocked state of the blocking means. When the blocking device assumes the blocking state, the output member is blocked from rotating about the output rotation axis. Even if the output member is blocked, the input member may rotate through the angular gap and energy may be harvested from this rotation of the input member.
Accordingly, the present disclosure provides a lock device for an electronic locking system, the lock device comprising: an input member arranged to rotate about an input rotation axis, the input member comprising an engagement formation; an output member arranged to rotate about an output rotation axis, the output member comprising an engageable structure arranged to be engaged by an engagement structure; an energy harvesting device configured to generate electrical energy from rotation of the input member in a first direction about the input rotation axis; and an inhibiting device movable with energy from the energy-collecting device between an inhibiting state in which the inhibiting device inhibits rotation of the output member about the output rotation axis and a release inhibiting state in which the output member is permitted to rotate about the output rotation axis; wherein the engagement structure is rotatable in the first direction about the input rotation axis through the angular gap prior to engagement with the engageable structure.
The blocking means may for example comprise a movable blocking member which is moved into a recess in the output member when the blocking state is assumed and which is moved out of the recess when the unblocking state is assumed.
The angular gap may be 45 ° to 135 °, such as 80 ° to 100 °, such as 90 ° about the input rotation axis. Throughout this disclosure, the angular gap may alternatively be referred to as a sector or a free sector.
The engagement structure may comprise at least one engagement projection. The at least one engagement protrusion may be constituted by a pin. The engageable structure may comprise at least one engageable protrusion. The at least one engageable protrusion is constituted by a stop.
According to another variant, the transmission means are constituted by coupling means movable between a uncoupled state, in which the input member is uncoupled from the output member, and a coupled state, in which the input member is coupled to the output member. In the coupled state of the coupling device, the input member may be fixedly coupled to the output member, for example so as to rotate jointly about the input rotation axis. Throughout the present disclosure, the uncoupled state and the coupled state of the coupling device may be constituted by the uncoupled position and the coupled position, respectively.
Energy may be harvested from the rotation of the input member even if the rotation of the input member is not transferred to the output member. Thus, with this variation, energy harvesting may be performed prior to coupling the input member to the output member.
In this variant, the locked state of the transmission means is constituted by the uncoupled state of the coupling means, and the unlocked state of the transmission means is constituted by the coupled state of the coupling means. The lock device of this variant can be arranged in a lock housing.
Accordingly, the present disclosure provides a lock device for an electronic locking system, the lock device comprising: an input member arranged to rotate about an input rotation axis; an output member arranged to rotate about an output rotation axis; an energy harvesting device configured to generate electrical energy from rotation of the input member in a first direction about the input rotation axis; and a coupling device movable between a decoupled state in which the input member is decoupled from the output member and a coupled state in which the input member is coupled to the output member; and wherein the coupling device is powered by the energy harvesting device.
According to another variant, the transmission means are constituted by blocking and coupling means comprising: a blocking portion movable between a blocking state in which the blocking portion blocks rotation of the output member about the output rotation axis and a release blocking state in which the output member is allowed to rotate about the output rotation axis; and a coupling portion movable between a decoupled state in which the input member is decoupled from the output member and a coupled state in which the input member is coupled to the output member; wherein the coupling portion is arranged to move between the uncoupled state and the coupled state in conjunction with movement of the blocking portion between the blocking state and the unblocking state. Throughout the present disclosure, the blocking state and the unblocking state of the blocking portion may be constituted by a blocking position and an unblocking position, respectively. Also, throughout the present disclosure, the uncoupled state and the coupled state of the coupling portion may be constituted by the uncoupled position and the coupled position, respectively.
In this variant, the locked state of the transmission means is constituted by the locked state of the blocking and coupling means, and the unlocked state of the transmission means is constituted by the unlocked state of the blocking and coupling means. The locked state of the blocking and coupling means is in turn constituted by the blocking state of the blocking portion and by the uncoupled state of the coupling portion. Further, the unlocked state of the blocking and coupling means is constituted by the unblocked state of the blocking portion and by the coupled state of the coupling portion.
Accordingly, the present disclosure provides a lock device for an electronic locking system, the lock device comprising: an input member arranged to rotate about an input rotation axis; an output member arranged to rotate about an output rotation axis; an energy harvesting device configured to generate electrical energy from rotation of the input member in a first direction about the input rotation axis; and a blocking and coupling device including a blocking portion and a coupling portion, the blocking portion being movable between a blocking state in which the blocking portion blocks rotation of the output member about the output rotation axis and a release blocking state in which the output member is allowed to rotate about the output rotation axis; and a coupling portion movable between a decoupled state in which the input member is decoupled from the output member and a coupled state in which the input member is coupled to the output member; wherein the coupling portion is arranged to be moved between the uncoupled state and the coupled state by means of movement of the blocking portion between the blocking state and the unblocking state.
When the coupling portion assumes the uncoupled state, the input member is free to rotate about the input rotation axis. Thus, energy from this rotation can be collected by the energy harvesting device. The lock device of this variation may include an actuator powered by the energy harvesting device. The actuator may be arranged to push the blocking portion from the blocking state to the unblocking state and to pull the blocking portion from the unblocking state back to the blocking state.
When the lock device comprises a blocking and coupling device according to the present disclosure, the input and output rotation axes may be concentric. In this case, the input member and the output member may be coupled to rotate together about a common axis of rotation, for example about the input axis of rotation and the output axis of rotation, in the coupled state of the coupling portion.
The coupling portion may be moved from the uncoupled state to the coupled state by movement (e.g., by pushing and/or pulling) of the blocking portion from the blocked state to the unblocked state. Conversely, the coupling portion may be moved from the coupled condition to the uncoupled condition by movement (e.g., by pushing and/or pulling) of the blocking portion from the unblocking condition to the blocking condition.
The movement of the coupling portion between the uncoupled and coupled conditions and the consequent movement of the blocking portion between the blocked and unblocked conditions may be in a direction substantially perpendicular or perpendicular to the input rotation axis. When the coupling portion assumes the coupled state, rotation of the input member about the input rotation axis may be transmitted as movement of the coupling portion in a direction substantially perpendicular or perpendicular to movement of the blocking portion between the blocking state and the unblocking state. Movement of the coupling portion in a direction substantially perpendicular or perpendicular to movement of the blocking portion between the blocking state and the unblocking state may be transferred as a rotation of the output member about the output rotation axis. In this way, the input member is coupled to the output member.
The prevention portion may include a frame. In this case, the coupling portion may be constituted by a slider member movable within the frame. The slider member may for example be guided along a track in the frame.
The slider member may comprise a plate, for example a plate oriented substantially perpendicular or perpendicular to the input rotation axis. The slide member may further comprise an input member engagement profile on a side of the plate facing the input member and an output member engagement profile on an opposite side of the plate facing the output member. The input member may comprise an input member engageable profile for engagement by the input member engagement profile when the coupling portion assumes the coupled condition. The output member may comprise an output member engageable profile for engagement by the output member engaging profile when the coupling portion assumes the coupled condition. The input member engagement profile and/or the output member engagement profile may be constituted by or comprise one or more pins. The input member engageable profile and/or the output member engageable profile may be constituted by or comprise one or more teeth for being engaged by respective pins when the coupling section assumes the coupled condition. The one or more pins of the input member engagement profile and the output member engagement profile may be arranged substantially perpendicular or perpendicular to the frame.
According to another variant, the lock device further comprises a geneva gear having a rotatable drive wheel and a rotatable driven wheel, wherein the drive wheel is rotatable by rotation of the input member about the first axis of rotation when the transmitting means assumes the unlocked state, wherein the drive wheel is not rotatable by rotation of the input member about the first axis of rotation when the transmitting means assumes the locked state, and wherein the output member is constituted by the driven wheel. There are various types of geneva mechanisms. The sheave mechanism according to the present disclosure is configured to transmit continuous rotation of the drive wheel to intermittent rotation of the driven wheel. To this end, the drive wheel may include a pin, while the driven wheel may include one or more slots for engagement by the pin. In this variant, the lock device may further comprise a blocking device configured to selectively block the driven wheel.
The drive wheel may include a blocking disc. The driven wheel may include a plurality of web portions and arcuate recesses between the web portions. In this case, each of the arc-shaped recesses has a curvature that conforms to a curvature of the catch disk. Thus, a latch connected to or integrally formed with the driven wheel cannot be rotated by manipulation of the latch when the blocking disk is received in one of the arcuate recesses.
The lock arrangement may further comprise a differential, the differential comprising: a rotatable differential input connected to, coupled to, integrally formed with, or comprised of the input member; a rotatable differential output connected to, coupled to, integrally formed with, or comprised of a drive wheel; and a rotatable ring gear; wherein the differential is configured to transmit rotation of the differential input as rotation of the differential output when the ring gear is blocked and not transmit rotation of the differential input as rotation of the differential output when the ring gear is unblocked; and wherein the transmission means is constituted by blocking means movable between a blocking state in which the blocking means blocks the ring gear and a unblocking state in which the blocking means unblocks the ring gear. Throughout the present disclosure, the blocking state and the unblocking state of the blocking device may be constituted by a blocking position and a unblocking position, respectively. The differential may be constituted by a ball differential, for example.
A lock device including a geneva gear according to the present disclosure need not necessarily include a differential. Alternatively or additionally, the lock arrangement may comprise a blocking arrangement configured to selectively block the driven wheel in order to cause the lock arrangement to adopt the locked state and the unlocked state.
The unblocked state of the blocking device thus constitutes the locked state of the transmission device, and the blocked state of the blocking device thus constitutes the unlocked state of the transmission device.
The lock device may further comprise a handle connected to or integrally formed with the input member. The handle may for example be constituted by an elongated handle or by a knob. Thus, throughout the present disclosure, the input member may be constituted by a handle shaft.
Alternatively or additionally, the lock arrangement may further comprise a latch connected to or integrally formed with the output member. Thus, throughout the present disclosure, the output member may be constituted by a latch shaft.
The energy harvesting device may include: a generator; a drive member arranged to drive the generator, the drive member being displaceable from a starting position to a release position by means of an input member; a resilient element arranged to store mechanical energy resulting from displacement of the drive member from the home position to the release position; and a release mechanism arranged to release the mechanical energy stored in the resilient element to cause the drive member to perform a return displacement when the drive member reaches the release position.
The release mechanism is a mechanism configured to release the drive member. The release mechanism may be configured to release the drive member at a specific position of the drive member, i.e. at a release position. In case the drive member is movable in a rotational manner about the drive member rotation axis between a starting position and a release position, the release mechanism may be configured to release the drive member at a specific rotational position of the drive member, i.e. at the release position.
The release mechanism may for example comprise a release member connected to the drive member and a fixed release member activator such as a stop. In this case, when the drive member has been moved from the start position to the release position, the release member may be brought into contact with the release member activator, for example by means of a drive pin fixed to the input member, such that the release member activator activates the release member. The actuation may consist of pushing the release member from the extended position to the retracted position. Thus, the engagement between the drive pin and the release member disappears, and the release mechanism is released.
The drive member is displaceable by means of rotation about an input rotation axis. In this case, the angular distance about the input rotation axis between the starting position and the release position may be less than 90 °, such as 80 °.
However, the energy harvesting device according to the present disclosure is not limited to the above type nor to an energy harvesting device including a release mechanism. As an alternative example, the energy harvesting device may comprise a generator that is continuously driven by rotation of the input member about the input rotation axis, i.e. a direct drive energy harvesting device. This may be achieved, for example, by means of a drive gear attached to the input member and a driven gear connected to the rotor of the generator, wherein the drive gear is always in meshing engagement with the driven gear. That is, the drive gear is always coupled to the driven gear.
According to another aspect, there is provided an electronic locking system comprising a lock device according to the present disclosure and an electronic access control device capable of being powered by an energy harvesting device.
