Description

Technical Field

[0001] This application relates to an operating unit for controlling machine functions, and a method for operating the operating unit for controlling machine functions. Background Technology

[0002] The user interfaces of machines (such as vehicles) are becoming increasingly compact, which reduces the space available within the machine for arranging operating elements. Furthermore, the number of operating elements continues to increase. On the one hand, the limited available space within the machine makes the arrangement of operating elements more difficult; on the other hand, the large number of operating element choices makes operating the machine more complex and confusing for the user.

[0006] Therefore, it is necessary to mitigate at least some of the above-mentioned disadvantages and to provide an operating unit that occupies very little space and simplifies machine operation for the user.

[0007] This requirement is met by the features of the independent claim. The dependent claims describe embodiments of the invention.

[0008] According to an embodiment of the present invention, an operating unit is provided for controlling the functions of a machine (particularly a vehicle, such as an agricultural or construction vehicle, like a tractor or harvester). The operating unit includes: an operating module comprising one or more operating elements; and a drive mechanism. The operating module and the drive mechanism are configured to be disposed within a recess of the machine, and the drive mechanism is controllable to move the operating module at least from a retracted position to an extended position, in which at least one operating element of the operating module is positioned within the recess, and in the extended position, in which at least one operating element of the operating module is positioned outside the recess.

[0009] Space available in machines and vehicles is becoming increasingly limited. The proposed solution allows for more efficient use of available space in machines, particularly in vehicles. Operating units can be arranged in recesses already present in the machine, or recesses specifically designed for this purpose. Preferably, the recess is a machine armrest.

[0010] Furthermore, by moving the operating module between the retracted and extended positions via a drive mechanism, the operating unit allows the user to use only specific operating elements. That is, in the extended position, the operating element positioned inside the recess in the retracted position is positioned outside the recess. Specifically, the operating unit is configured such that the operating module moves to either the retracted or extended position depending on the acquired (e.g., selected) operating mode. The fact that not all operating elements are always located outside the recess and are therefore available to the user simplifies the operability of the operating unit and its operating elements. In particular, only the operating elements positioned outside the recess are currently needed, i.e., for the selected operating mode. Therefore, the user is not confused by multiple operating elements that are not needed for the current operating mode.

[0011] The operating element is preferably an element that, when actuated, causes a specific function in the machine to be performed. Preferably, the operating unit has a controller connected to the operating module, and particularly to the operating element, and configured to control / perform the functions of the vehicle when the operating element is actuated. Preferably, the operating element is a mechanically actuated element (i.e., without a touchpad or touchscreen), such as a (mechanical) knob, particularly a rotary knob, a lever, a slider, a switch, etc.

[0012] An operating element positioned outside or located within a recess may mean that the operating element is outside the recess and can be accessed and operated by the user. An operating element positioned within or located within a recess preferably means that the operating element cannot be accessed by the user and is therefore inoperable.

[0013] In the retracted position, all operating elements can be positioned within the recess (except for the operating elements optionally arranged on the cover element of the operating module as described below). In the fully extended position, all operating elements can be positioned outside the recess.

[0014] The recess preferably has an opening. Depending on the position of the operating module, the operating element can be positioned inside or outside the opening. Preferably, the opening of the recess is adapted to the external shape of the operating module.

[0015] The opening can be on a side surface, such as on a top surface or a vertical surface. The operating module is preferably movable in a (substantially) vertical or (substantially) horizontal direction.

[0016] In an alternative embodiment, the drive mechanism is controlled to move the operating module to at least one intermediate position between a retracted position and an extended position, wherein, in the at least one intermediate position, at least one operating element located inside the recess in the retracted position is located outside the recess, and wherein, in the extended position, at least one more operating element is located outside the recess than in the at least one intermediate position.

[0017] When the drive mechanism moves the operating module to at least one intermediate position, the operating module preferably remains or is maintained in at least one intermediate position. In the intermediate position, at least one operating element is preferably operable to control the function of the machine.

[0018] In an optional instance, at least one intermediate position is an operating position in which at least one operating element located outside the recess is operable.

[0019] At least one intermediate position may also be referred to as "at least one first extended position", and the extended position may also be referred to as "fully extended position".

[0020] At least one intermediate position may include a first intermediate position and a second intermediate position, wherein the second intermediate position is located between the first intermediate position and the extended position, wherein in the second intermediate position, the operating element located outside the recess has at least one more operating element than in the first intermediate position and at least one less operating element than in the extended position. The first intermediate position may also be referred to as the "first extended position", the second intermediate position may also be referred to as the "second extended position", and the extended position may also be referred to as the "fully extended position" of the operating module.

[0021] The fact that not all operating elements are always located outside the recess and are therefore available to the user simplifies the operability of the operating unit and its operating elements. In particular, only operating elements located outside the recess are currently required, i.e., for the acquired operating mode. Therefore, the user will not be confused by operating elements located outside the recess that are not needed for the current operating mode.

[0022] Preferably, the first intermediate position is located between the retracted position and the second intermediate position, and the second intermediate position is located between the first intermediate position and the fully extended position.

[0023] If, for example, a third intermediate position is provided, this third intermediate position can be located between the second intermediate position and the fully extended position.

[0024] The travel length (e.g., vertical or horizontal distance) of the operating modules between two adjacent positions can be equal or different.

[0025] Preferably, the operating unit includes a cover element configured to cover (close) the opening of the recess in a retracted position. Preferably, the operating module includes a cover element disposed at its end section, or the operating unit includes a cover element configured to be disposed at the opening of the recess, for example as part of a handrail.

[0026] In the retracted position, the cover element protects the interior of the recess from dust and other contaminants, and prevents damage to the drive mechanism and / or operating module.

[0027] When the cover element is arranged on the operating module, the controller can be configured to move the operating module to a retracted position, wherein the cover element arranged on the operating module covers (closes) the opening of the recess. That is, in the retracted position, the opening of the recess can be covered by the operating module itself. In the retracted position, at least one operating element arranged on the cover element can be positioned outside the recess.

[0028] Alternatively, in this retracted position, none of these operating elements can be positioned outside the recess; that is, all operating elements of the operating module are positioned inside the recess. For example, if no operating elements of the operating module are needed in the selected operating mode, the operating module can be retracted into the recess so that no operating elements are located outside the recess of the machine.

[0029] When the cover element is included in the operating unit and is arranged at the opening of the recess (i.e., not on the operating module), the controller can be configured to move the operating module to the retracted position and move the cover element arranged at the opening of the recess so that the recess cover element is closed.

[0030] The cover element simplifies operability because the user cannot access operating elements that are not currently needed. Furthermore, the operating module does not occupy any space within the machine (i.e., it is outside the recess), meaning the user has more space inside the machine. If the operating unit is arranged in the armrest, the armrest can be used to rest the arm when the operating module is in the retracted position.

[0031] If intermediate positions are provided, the operating module may include at least one intermediate cover element configured to close the opening of the recess in at least one intermediate position. Preferably, the operating module includes one intermediate cover element for each intermediate position. For example, the operating module may include a first intermediate cover element configured to close the opening of the recess in a first intermediate position. Alternatively, the operating module may include a second intermediate cover element (closed) configured to close the opening of the recess in a second intermediate position.

[0032] The operating module may include an end cap element configured to close the opening of the recess in the (fully) extended position.

[0033] The first intermediate cover element can be positioned between the end cover element and the second intermediate cover element. The second intermediate cover element can be positioned between the first intermediate cover element and the cover element.

[0034] In at least one intermediate position, at least one intermediate cover element (and in the extended position, the end cover element) protects the interior of the recess from dust and other contaminants and prevents damage to the drive mechanism and / or the operating module of the operating unit.

[0035] Preferably, one or more operating elements include at least one joystick having a base and a handle movably connected to the base, wherein, in an extended position of the operating module, the joystick is at least partially positioned outside the recess such that the handle is pivotable in at least one direction.

[0036] Specifically, in the retracted position, the joystick is positioned within the recess such that the handle cannot pivot, and in the extended position, the joystick is positioned at least partially outside the recess such that the handle can pivot in at least one direction.

[0037] Preferably, the handle can pivot in at least two directions perpendicular to each other. The handle of the joystick can be cylindrical.

[0038] At least some of the operating elements can be arranged on the handle of the joystick.

[0039] The joystick may include additional operating elements disposed on the base of the joystick (i.e., not on the handle). The operating elements on the handle and optionally on the base are preferably positioned outside the recess in the extended position of the operating module.

[0040] If the joystick does not need to be pivoted in at least one direction in the obtained operating mode of the machine, the pivotable portion of the joystick is preferably positioned in a recess so that the handle is not pivotable.

[0041] The end cap element configured to close the opening of the recess in the extended position of the operating module may be at least partially constituted or formed by the base of the joystick.

[0042] Preferably, the handle includes at least one or two operating elements, such as knobs. A first operating element, positioned within a recess in the retracted position, may be positioned outside the recess in a first intermediate position. Optionally, a second operating element, positioned within the recess in the first intermediate position, may be positioned outside the recess in a second intermediate position.

[0043] Preferably, the first and / or second intermediate cover element is disposed on the handle of the joystick. Preferably, the first operating element (e.g., a knob) is positioned between the first intermediate cover element and the second operating element (e.g., a knob) (or the second intermediate cover element). The second operating element (e.g., a knob) may be positioned between the first operating element (or the first intermediate cover element) and the second intermediate cover element.

[0044] The first rotary knob and / or the second rotary knob can rotate about a rotation axis corresponding to the longitudinal axis of the handle.

[0045] Preferably, the cover element covers the end section of the handle. Optionally, at least one of the operating elements is arranged on the cover element. In the retracted position of the operating module, the at least one operating element arranged on the cover element may be positioned outside the recess.

[0046] More preferably, in the retracted position of the operating module, only at least one operating element arranged on the cover element is positioned outside the recess.

[0047] Preferably, the operating unit includes a controller, wherein the controller is configured to control the drive mechanism to selectively move the operating module at least between a retracted position and an extended position.

[0048] If at least one intermediate position is provided, the controller is configured to control the drive mechanism to move the operating module between a retracted position, at least one intermediate position, and an extended position. Preferably, the controller is configured to control the drive mechanism to move the operating module to any intermediate position between the retracted position and the extended position.

[0049] Preferably, the controller is configured to acquire the operating mode of the machine and move the operating module to at least a retracted position, optionally at least one intermediate position (if configured), or a (fully) extended position according to the acquired operating mode.

[0050] The controller can obtain the operating mode from input via the user or from a higher-level controller of the machine. For example, the operating mode can be selected by the user by actuating the control element.

[0051] By positioning different operating elements outside the recess according to the acquired operating mode, it becomes clear to the user which operating elements are associated with the acquired operating mode. Therefore, the machine's operability is simplified, and the user is not confused by operating elements unrelated to the current operating mode.

[0052] For example, when a first operating mode is acquired, the controller can be configured to move the operating module to the retracted position, and when a second operating mode different from the first operating mode is acquired, the controller can be configured to move the operating module to the extended position.

[0053] If at least one intermediate position is provided, particularly the first and second intermediate positions, the controller may be configured to move the operation module to the first intermediate position when a third operating mode is acquired, and / or the controller may be configured to move the operation module to the second intermediate position if a fourth operating mode is acquired.

[0054] For example, the controller may acquire a first operating mode (e.g., when disconnecting or connecting the device to the machine), and the controller may be configured to move the operating module to any position—a retracted position, an intermediate position (if provided), and a (fully) extended position—in response to the acquired first operating mode. Furthermore, the controller may acquire a second operating mode (such as a mode for operating a component of the machine), and the controller may be configured to move the operating module to a position different from the position the operating module had moved to in response to the first operating mode, in response to the acquired second operating mode. If the operating element includes a joystick, the joystick may be used in the first operating mode to move the machine or operate a device connected to the machine, wherein in the second operating mode, the joystick is positioned within a recess and is inaccessible to the user.

[0055] Each position, or at least each extended position (e.g., a first and / or second intermediate position and a fully extended position), can be an operating position of the operating module, in which the operating element located outside the recess is operable, and can correspond to an operating mode of the machine. The operating unit can be controlled to hold the operating module in the corresponding operating position when the machine is operating in the relevant operating mode. The operating element within the recess in the corresponding operating position may be inoperable.

[0056] Preferably, the operating unit includes a position detection device configured to detect (e.g., without contact) the current (absolute) position of the operating module and transmit a position signal indicating the detected position to the controller.

[0057] The position detection device can detect the current position of the operating module along its direction of movement. The direction of movement of the operating module can be vertical, horizontal, or any direction in between. Preferably, the direction of movement is vertical or substantially vertical.

[0058] The position detection device may include a position sensor disposed on the operating module or within a recess. The position detection device may be configured to detect the absolute position of the operating module within the recess. Preferably, the position detection device includes an inductive sensor, an optical sensor, or a resistive sensor for detecting the current position of the operating module.

[0059] Preferably, the controller is configured to move the operating module to a retracted position, an extended position, or at least an intermediate position based on a detected position signal. The controller can use feedback from a position sensor to bring the operating module to a corresponding predetermined absolute position. The predetermined absolute position can be assigned to each of the operating module's retracted position, at least an intermediate position (if provided), and (fully) extended position. Preferably, each position of the operating module—the retracted position, the extended position, or at least an intermediate position—corresponds to a specific absolute position.

[0060] This allows for high-precision access to various positions of the operating module. When, for example, the machine is disconnected and reconnected, the position detection device can detect the current position of the operating module, and based on the current position, the controller can move the operating module to a specific position corresponding to one of a retracted position, an extended position, and optionally at least one intermediate position.

[0061] Preferably, the drive mechanism includes a guide device adapted to guide the operating module between a retracted position and an extended position. More preferably, the guide device includes at least two guide elements that, in the installed state, extend (substantially) parallel to the direction of movement of the operating module.

[0062] Preferably, the operating module includes a rolling or sliding element attached to the operating module, wherein the rolling or sliding element is received by a guiding device, wherein the rolling or sliding element is movably arranged on the guiding device, and wherein the operating module can be moved from a retracted position to an extended position (or to any intermediate position therebetween) by moving the rolling or sliding element on the guiding device.

[0063] The rolling or sliding element may be at least partially surrounded by guide elements (e.g., guide rails), or the rolling or sliding element may at least partially surround these guide elements or guide rails from the outside. The rolling element may be, for example, a roller that rolls on the guide element during movement. The sliding element may be an element that slides on the guide element during movement. Compared to the rolling element, the sliding element does not roll on the guide element; that is, the sliding element is preferably a non-rotatable element that can slide on a rigid guide element.

[0064] The operating module is preferably arranged on a support structure, and the support structure is movable between a retracted position and an extended position. A rolling or sliding element is preferably arranged on the support structure such that the support structure is guided in a guide element by the rolling or sliding element. The rolling or sliding element is preferably arranged in the edge region of the operating module or the support structure. Preferably, the support structure is a plate element. The base of the joystick may be arranged on or connected to the support structure, or the base of the joystick may be part of or form part of the support structure.

[0065] Preferably, the rolling or sliding element and the driven element are arranged on opposite sides of the support structure.

[0066] The guiding device may have at least two guiding elements designed as rods, wherein each of the rolling or sliding elements is movable on a corresponding rod. The rolling or sliding element is configured to (at least partially) surround the corresponding rod. Specifically, the sliding element is formed as a sleeve, which is configured to slide on the corresponding rod.

[0067] Preferably, the drive mechanism may include an actuator configured to mechanically drive the drive mechanism to move the operating module between a retracted position and an extended position. The actuator may be, for example, an electric motor, a pneumatic actuator, a hydraulic actuator, a hydraulic piston, a hydraulic motor, etc.

[0068] The drive mechanism may include a drive element driven by an actuator, and the drive element is configured to be rotatably supported in a recess (e.g., a threaded rod or a gear / pinion), and the drive mechanism also includes a driven element disposed on an operating module (e.g., a threaded sleeve or a rack), the drive element engaging with the driven element such that by operating the actuator, the operating module can be moved from a retracted position to an extended position via the driven element (optionally from the retracted position to at least one intermediate position and from at least one intermediate position to the extended position).

[0069] More preferably, the driving element is a threaded rod or a toothed gear, and the driven element is a threaded sleeve or a toothed rack.

[0070] The threaded rod can have a trapezoidal thread or it can be a recirculating ball screw.

[0071] The axis of rotation of the threaded rod or the extension of the rack is preferably aligned parallel to the guide element.

[0072] Preferably, the drive mechanism includes a transmission assembly disposed within the recess and configured to transmit torque from the actuator to the operating module. The transmission assembly may include a first gear rotatably connected to the actuator and a second gear rotatably connected to a drive element (e.g., a threaded rod or gear / pinion), the first gear engaging the second gear such that by operating the actuator, the operating module is moved between a retracted position and an extended position by torque transmitted from the actuator to a driven element of the operating module via the first and second gears and the drive element.

[0073] The transmission assembly allows the actuator to be positioned close to the drive element, resulting in a more compact overall operating unit. Therefore, the operating unit can be installed in recesses with limited space. Furthermore, the operating module can be moved within a small space.

[0074] Preferably, the transmission assembly is configured to provide a reduction in the rotational speed of the actuator. This results in low torque for moving the drive element, which also means that almost no braking torque is needed when a force is applied to the operating module in the direction of movement of the operating module (e.g., the force when a user operates the operating module).

[0075] The drive mechanism can be self-locking and / or backlash-free.

[0076] Preferably, if no driving torque is applied to the drive mechanism, i.e., if the operating module is stationary, the operating module remains in its current position and does not move, even if a force (e.g., a force applied by the user) is applied to the operating module in the direction of its movement. This also preferably applies when the machine and therefore the operating unit are disconnected.

[0077] The holding force of the drive mechanism (i.e., the force that must be applied to move the operating module) is preferably greater than the normal force applied by the user to the operating module or its operating elements (excluding misuse). This ensures that the operating module does not change its position when used by the user, which enables reliable operation of the machine via the operating unit.

[0078] According to another embodiment of the invention, a machine is provided, such as a mobile machine, particularly an agricultural vehicle, construction vehicle, or industrial vehicle. The machine includes a recess having any of the configurations described herein and an operating unit having any of the configurations described herein, wherein the operating unit is mounted to or disposed within the recess.

[0079] According to another embodiment of the present invention, a method is provided for operating an operating unit for controlling a machine, particularly an operating unit as described herein. The operating unit includes: an operating module comprising one or more operating elements; and a drive mechanism; wherein the operating module and the drive mechanism are arranged in a recess of the machine. The method includes moving the operating module from a retracted position to an extended position via the drive mechanism, wherein in the retracted position at least one operating element of the operating module is positioned within the recess, and in the extended position at least one operating element of the operating module is positioned outside the recess.

[0080] The method may also include moving the operating module from a retracted position or an extended position to any intermediate position between the retracted and extended positions (as described above). The movement of the operating module may occur depending on the acquired operating mode of the machine.

[0081] This method may include any of the steps described herein with respect to the operating unit and the machine. Furthermore, the operating unit and the machine may be configured to perform any of the disclosed method steps.

[0082] It should be understood that the features mentioned above, as well as those to be described below, can be used not only in the indicated corresponding combinations, but also in other combinations or individually, without departing from the scope of the invention. Specifically, features of different aspects and embodiments of the invention can be combined with each other, unless otherwise indicated. Attached Figure Description

[0091] In the following, embodiments of the invention will be described in detail with reference to the accompanying drawings. It should be understood that the following description of the embodiments is given for illustrative purposes only and should not be construed as limiting. It should be noted that the drawings are to be regarded as schematic representations only, and the elements in the drawings are not necessarily to scale. Rather, various representations of elements have been chosen such that their function and general purpose will become apparent to those skilled in the art. As used herein, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well. Unless otherwise indicated, the terms “comprising,” “having,” “including,” and “containing” should be interpreted as open-ended terms (i.e., meaning “including but not limited to”).

[0092] Figure 1 This is a schematic side view illustrating the operation unit 10 used for controlling the machine. The operation unit 10 includes: an operation module 12, comprising one or more operation elements 14a-c; and a drive mechanism 16. Figure 1 As shown, the operation module 12 and the drive mechanism 16 are configured to be disposed in the recess 20 of the machine.

[0093] The drive mechanism 16 can be controlled to move the operating module 12 at least from the retracted position P0 (e.g., Figure 1 (As shown) Move to the extended positions P1, P2 (see) Figure 2 and 3 In the retracted position, at least one operating element 14b, 14c of the operating module 12 is positioned inside the recess 20; in the extended position, at least one operating element 14b, 14c of the operating module 12 is positioned outside the recess 20. The direction of movement of the operating module 12 is determined by... Figure 1 The arrows in the diagram indicate this. Specifically, the operating module 12 is movable through the opening 22 of the recess 20. Therefore, it is possible that only the operating elements 14a-c required for the selected operating mode are located outside the recess 20 and are thus operable by the user. Thus, user operability is simplified because operating elements unrelated to the current operating mode are inaccessible (i.e., located inside the recess), and therefore the user is not confused when operating the operating module.

[0094] For example, and as Figures 1 to 3As shown, the operating module 12 is preferably movable in a vertical or substantially vertical direction. However, it should be understood that, alternatively, the operating module 12 can be moved in a horizontal direction or any other direction. For example, the opening 22 of the recess can be arranged on the side surface of the machine component where the recess is provided. Regardless of the direction of movement of the operating module 12, in each extended position, at least one more external operating element is positioned in the recess 20 compared to the previous extended or retracted position.

[0095] The drive mechanism 16 may include a guide device 50 adapted to guide the operation module 12 from the retracted position P0 to the extended positions P1, P2. Figure 4 (Exemplary embodiments are shown). The guiding device 50 may include at least two guiding elements 52 that, in the installed state, extend parallel to or substantially parallel to the direction of movement of the operating module 12. For example, the guiding elements 52 extend vertically from the bottom of the recess to the top region of the recess 20. The drive mechanism 16 preferably includes a drive element 64 (e.g., a threaded rod) driven by an actuator 56 (e.g., an electric motor) and configured to be rotatably supported in the recess 20. The drive mechanism 16 may also include a driven element 66 (e.g., a threaded sleeve) disposed on the operating module 12, wherein the drive element 64 engages with the driven element 66 such that, by operating the actuator 56, the operating module 12 can be moved from a retracted position P0 to an extended position P1, P2 by means of the driven element 66.

[0096] The drive mechanism 16 may further include a transmission assembly 58 disposed within the recess 20 and configured to transmit torque from the actuator 56 to the operating module. The transmission assembly 58 may include a first gear 60 rotatably connected to the actuator 56 and a second gear 62 rotatably connected to a threaded rod 64. The first gear 60 engages with the second gear 62 such that, by operating the actuator 56, the operating module 12 moves between a retracted position P0 and extended positions P1, P2 by torque transmitted from the actuator to the threaded sleeve 66 of the operating module via the first and second gears 60, 62 and the drive element 64. Preferably, the drive mechanism 16 is self-retaining and / or backlash-free. Therefore, when a force is applied (e.g., by a user) in the direction of movement of the operating module 12, the operating module 12 remains in place.

[0097] The operating module 12 may include a support structure 40, which can be moved by actuation of the threaded rod 64. The support structure 40 may be a plate element. Preferably, the driven element 66 (e.g., a threaded sleeve) is included in the support structure 40, such as... Figure 1As shown. Preferably, the support structure 40 includes a rolling or sliding element (not shown), wherein the rolling or sliding element is received by the guide device 50, wherein the rolling or sliding element is movably arranged on the guide device 50, and wherein, by moving the rolling or sliding element on the guide device 50, the operation module 12 can move from the retracted position P0 to the extended positions P1, P2.

[0098] like Figure 1 As shown, the operation module 12 may include three operation elements 14a-c, each arranged at a different vertical position. However, the number of operation elements at the same or different vertical positions is arbitrary. Figure 1 In the retracted position P0, operation module 12 has operation elements 14b and 14c positioned within the recess, while operation element 14a is positioned outside the recess. In this position, only operation element 14a is accessible and therefore operable by the user.

[0099] Furthermore, the operation module 12 may include a cover element 36 disposed at its end section, wherein the cover element 36 is configured to... Figure 1 The opening 22 of the recess is closed in the retracted position P0. An operating element 14a may be arranged on a cover element 36, which is located outside the recess 20 in the retracted position P0. Therefore, in the retracted position P0, the cover element 36 protects the interior of the recess from dust and other contaminants, and prevents damage to the drive mechanism 16 and / or the operating module 12.

[0100] like Figures 1 to 3 As shown, the operation module 12 can be selectively moved from the retracted position P0 via the drive mechanism 16 (see...). Figure 1 Move to the first extended position P1 (see) Figure 2 ) or move to the second extended position P2 (see Figure 3 The first extended position P1 corresponds to the intermediate position of the operating module between the retracted position P0 and the fully extended position P2.

[0101] In the first extended position P1, compared to the retracted position P0, one or more operating elements (i.e., operating element 14b) are positioned outside the recess 20. Operating element 14b is therefore operable by the user.

[0102] In the second extended position P2, compared to the first extended position P1, one or more operating elements (i.e., operating elements 14c) are positioned outside the recess 20. Operating elements 14c are therefore operable by the user.

[0103] The operating unit 10 may include a controller 68, wherein the controller is configured to control the drive mechanism 16 to selectively move the operating module 12 at least between a retracted position P0 and a first extended position P1 and a second extended position P2. For simplicity, the controller 68 only... Figure 1 As shown in and Figures 2 to 4 The middle part is omitted. However, the features of controller 68 are also applicable to... Figures 2 to 4 .

[0104] The controller 68 can be configured to obtain the machine's operating mode from the machine's superior controller or from user input (not shown), and move the operating module 12 to the retracted position P0 or the first extended position P1 or the second extended position P2 according to the obtained operating mode.

[0105] The operating unit 10 may include a position detection device 70 configured to detect (preferably non-contact) the current (absolute) position of the operating module 12 and transmit a position signal indicating the detected position to the controller 68. The controller 68 may use feedback from the position sensor 72 of the position detection device 70 to move the operating module 12 to a corresponding predetermined absolute position, i.e., to move the operating module 12 to a retracted position P0, a first extended position P1, or a second extended position P2 based on the detected position signal. The sensor 72 may be arranged in a manner such as... Figure 1 The operation module 12 shown is located thereon. However, alternatively, the sensor 72 may be arranged within the recess (i.e., not on the operation module 12).

[0106] Therefore, the controller 68 is preferably connected to the drive mechanism 16, the operating elements 14a-c, and preferably to the position sensor 72.

[0107] Controller 68 may be a separate controller connected to receive user input (e.g., disposed within the recess) and / or a higher-level controller connected to the machine. Alternatively, controller 68 may be integrally formed within the controller of the machine or may be formed by the controller disposed outside the recess within the machine.

[0108] Figure 4 This is a schematic cross-sectional side view showing an operation unit 10 with an operation module 13 according to an embodiment, wherein the operation module 13 is in a fully extended position. The operation unit 10 is similar to... Figures 1 to 3 The operation unit shown is the same as that of operation module 12, but operation module 13 is a variation of operation module 12. In the following description, only the differences in operation module 13 will be described. Regarding... Figures 1 to 3 All other features described in the implementation method can also be applied to Figure 4 The implementation shown is illustrated.

[0109] Similar to Figures 1 to 3 The operation module 12 shown is shown. Figure 4 The operating module 13 shown includes three operating elements 14a-c arranged in different (e.g., vertical) positions. However, the number of operating elements in the same or different vertical positions is arbitrary. Figures 1 to 3 Compared to the operation module 12 shown, Figure 4 The illustrated operating module 13 includes an additional operating element, namely a joystick 30. The joystick 30 includes a base 32 and a handle 34 movably connected to the base 32. Figure 4 As shown, the operating elements 14a-c are arranged on the handle 34 of the joystick 30.

[0110] For example, the operating module 13 may include only the joystick 30 (i.e., operating elements 14a, 14b, 14c are optional and may not be provided), wherein in the retracted position P0, no operating element is positioned outside the recess 20, and in the fully extended position, the joystick 30 is positioned outside the recess such that the handle 34 is pivotable in at least one direction (movement of the handle 34 is indicated by arrows). In another example, the operating module 13 may include the joystick 30 and operating element 14a (i.e., operating elements 14b, 14c are optional and may not be provided), wherein in the retracted position P0, only operating element 14a is positioned outside the recess, and in the fully extended position, both operating element 14a and the joystick 30 are positioned outside the recess such that the handle 34 is pivotable in at least one direction.

[0111] The base 32 is preferably arranged on the support structure 40, or the base 32 forms or includes the support structure 40 which can be moved by the drive element 64.

[0112] The cover element 36 of the operating module 13 can cover the end section of the handle 34. The operating element 14a can be arranged on the cover element 36. The cover element 36 can be configured to cover the opening 22 of the recess in the retracted position P0. Therefore, in the retracted position P0, the cover element 36 protects the interior of the recess from dust and other contaminants, and prevents damage to the drive mechanism 16 and / or the operating module 12.

[0113] The drive mechanism 16 is preferably controllable to move the operation module 13 from the retracted position P0 to at least one extended position P1, P2, P3. In the retracted position, the operation elements 14b, 14c and the joystick 30 of the operation module 12 are located within the recess 20. In the extended position, one or more of the operation elements 14b, 14c and / or the joystick 30 are located outside the recess 20.

[0114] Figure 4 The fully extended position P3 of the operating module 13 is shown, but not shown. Figure 4The other positions P0, P1, and P2 of the operation module 13 indicated in the text. However, positions P0, P1, and P2 correspond to... Figures 1 to 3 The positions P0, P1, and P2 of the operation module 12 shown are referenced to the information about Figures 1 to 3 The features described in the embodiments shown are as follows.

[0115] For example, in the retracted position P0, the operating elements 14b, 14c and the joystick 30 are positioned within the recess 20. In this position, the operating element 14a, arranged on the cover element, is positioned outside the recess 20 and is therefore operable by the user. The operating elements 14b, 14c and the joystick 30 located within the recess 20 are not accessible / operable by the user.

[0116] In the first extended position P1 (corresponding to a first intermediate position between the retracted position P0 and the fully extended position P3), the operating element 14b is positioned outside the recess 20 compared to the retracted position P0. The operating element 14b is therefore operable by the user. The user cannot access / operate the operating element 14c and the joystick 30 (partially) located within the recess 20.

[0117] In the second extended position P2 (corresponding to a second intermediate position between the retracted position P0 and the fully extended position P3 of the operating module), the operating element 14c is positioned outside the recess 20 compared to the first extended position P1. The operating element 14c is therefore operable by the user. The user-inaccessible / operable joystick 30 is (partially) positioned within the recess 20.

[0118] In the third extended position P3 (corresponding to the fully extended position of the operating module), the handle of the joystick 30 is positioned outside the recess 20, such that the handle 34 of the joystick can pivot in at least one direction. Therefore, the joystick 30 can be operated by the user. In this position, all operating elements 14a-c and the handle 34 of the joystick are located outside the recess 20 and are therefore accessible / operable by the user.

[0119] The controller can be configured to control the drive mechanism 16 so that the operation module 12 selectively moves between the retracted position P0 and the first extended position P1, the second extended position P2 and the third extended position P3 (i.e., the first intermediate position, the second intermediate position and the fully extended position) in particular, according to the acquired operation mode.

[0120] Figure 5 This is a schematic perspective view showing the operating elements of the operating module according to an embodiment. The operating module 13 includes a joystick 30 having a handle 34 and a base 32, as shown in [reference needed]. Figure 4 As described. The handle 34 is shown as cylindrical, but can be ergonomically shaped.

[0121] like Figure 5 As shown, operating elements 14a-c are arranged on the handle 34 of the joystick 30. Specifically, operating element 14a is arranged on a cover element 36, which covers the end section of the handle 34 on the side opposite to the base 32. The cover element 36 can be configured to cover the opening of the recess in the retracted position P0 of the operating module (see...). Figures 1 to 4 ).

[0122] The operating elements 14b and 14c can be formed as knobs, particularly rotating rings, which are arranged at different positions along the longitudinal axis of the handle 34.

[0123] In addition to or as a substitute for cover element 36, one or more cover elements may be provided at the operation module 13.

[0124] If multiple intermediate positions are provided, the operation module 13 may include at least one intermediate cover element 37, 39, which is configured to close the opening of the recess in at least one intermediate position. Preferably, the operation module 13 includes one intermediate cover element 37, 39 for each intermediate position.

[0125] The first intermediate cover element 37 may be disposed on the handle 34, wherein preferably, the first intermediate cover element 37 is disposed on the end section of the handle 34 opposite to the cover element 36. The first intermediate cover element 37 may also cover the end section. The first intermediate cover element 37 may be configured to close the opening 22 of the recess in the first intermediate position P1 of the operating module (see...). Figure 2 ).

[0126] The second intermediate cover element 39 may be disposed on the handle 34, wherein preferably, the second intermediate cover element 39 is disposed between the operating elements 14b, 14c (and thus between the cover element 36 and the first intermediate cover element 37). The second intermediate cover element 39 may be configured to close the opening 22 of the recess in the second intermediate position P2 of the operating module.

[0127] End cap element 41 may be disposed on the base 32 of the lever 30, wherein, preferably, end cap element 41 is disposed on the side of the base 32 facing the handle 34 and specifically facing the first intermediate cap element 37. End cap element 41 may be configured to close the opening 22 of the recess in the fully extended position P3 of the operating module (see... Figure 4 or Figure 6 Preferably, the end cap element 41 is included in or formed from the base 32 of the lever 30.

[0128] In the first and second intermediate positions, the intermediate cover elements 37, 39 (and in the fully extended position, the end cover element 41) protect the interior of the recess 20 from dust and other contaminants and prevent damage to the drive mechanism and / or the operating module of the operating unit.

[0129] Regarding the intermediate cover elements 37, 39 and the end cover 41 Figure 4 and Figure 5 The joystick 30 shown is disclosed. However, it should be clear that these components are also applicable to... Figures 1 to 3 Other embodiments not shown include the joystick. Intermediate cover elements 37, 39 and end cap 41 may be arranged on the operating module 12 and may have the functions described above.

[0130] exist Figures 1 to 4 In the diagram, recess 20 is shown as a general recess. For example... Figure 6 As shown, the recess in which the operating unit 10 described herein is arranged can preferably be disposed in the machine's armrest 74. Specifically, in Figure 6 In the diagram, the operation module 13 is shown in the fully extended position P3.

[0131] like Figures 1 to 4 As shown, an operating module and an operating element 14a-c are arranged at each different vertical position. However, it should be understood that more than one operating element 14a-c can also be arranged at all different vertical positions. Furthermore, additional operating elements can be arranged at other vertical positions. Therefore, more than... Figure 3 The first and second extension positions P1, P2 and Figure 4 The first, second, and third extension positions P1, P2, and P3 in the middle.

[0132] Preferably, the drive mechanism 16 can move the operation modules 12 and 13 to any position where the operation elements are assigned (e.g., such as...). Figures 1 to 4 (As shown in the vertical position), when the operating modules 12, 13 are moved from the retracted position P0 to the extended position, at least one operating element is positioned further outward outside the recess 20 than in the retracted position. Therefore, it is possible that only the operating elements 14a-c (and / or the joystick 30) required for the selected operating mode are positioned outside the recess 20 and are thus user-operable. User operability is thus simplified because operating elements unrelated to the current operating mode are inaccessible (i.e., positioned within the recess), and therefore the user is not confused when operating the operating modules.

[0133] In addition, operation modules 12 and 13 can be used only Figure 4 In the implementation method, it moves from the retracted position P0 to the fully extended position P3, or in Figure 3In this embodiment, the movement proceeds from the retracted position P0 to the fully extended position P2, meaning there is no intermediate position between the retracted and fully extended positions. In this case, in the retracted position P0, at least one of the operating elements is positioned within the recess 20, and in the fully extended position, the at least one operating element positioned within the recess 20 in the retracted position P0, preferably all operating elements, are positioned outside the recess.

[0134] Figure 7 This is a flowchart illustrating a method for operating the operation unit according to an embodiment.

[0135] In the first method step S1, the controller 68 acquires the machine's first operating mode. For example, the controller 68 acquires the operating mode from user input or from the machine's superior controller.

[0136] In the second method step S2, operation modules 12 and 13 (in Figures 1 to 4 (As shown in the diagram) The operation module moves from a retracted position P0 to an extended position (e.g., a first extended position P1) via a drive mechanism. In the retracted position, at least one operating element of the operation module is located within the recess 20, and in the extended position, at least one operating element of the operation module is located outside the recess. Therefore, only those operating elements are positioned outside the recess 20, which is currently required, i.e., necessary for the acquired operating mode. Thus, the user will not be confused by operating elements positioned outside the recess that are not necessary for the current operating mode.

[0137] In the third method step S3, the controller 68 can acquire user input for controlling the machine by operating at least one of the operating elements located outside the recess. Depending on the user input (i.e., actuating the control element), a specific function of the machine is controlled / executed.

[0138] This method can be repeated. For example, controller 68 can obtain a second operating mode from user input or from a higher-level controller of the machine. According to the second operating mode, operating modules 12 and 13 can move from a current extended position (e.g., a first extended position P1) to another position, wherein the number of operating elements positioned outside the recess differs from the number of operating elements outside the recess in the previous position. For example, the operating module moves from the (first) extended position to another extended position (e.g., a second or third extended position P2, P3), in which at least one more operating element is positioned outside the recess compared to the previous (first) extended position P1. In another example, the operating module moves from the (first) extended position P1 to a retracted position P0, in which at least one fewer operating element is positioned outside the recess compared to the previous extended position.

[0139] Therefore, depending on the first and second operating modes, the operating module moves to different positions, for example, to a first extended position in the first operating mode and to a second extended position in the second operating mode (i.e., the first extended position is positioned between the retracted position and the second extended position). Thus, only the operating element required for the acquired operating mode is located outside the recess, and therefore the user can access and operate it. However, it should be understood that different operating modes may also exist, which cause the operating module to move to the same position, such that the same operating element can be positioned outside the recess in different operating modes.

[0140] Preferably, when the machine is turned off, the controller 68 is configured to automatically move the operation modules 12 and 13 to the retracted position P0.

[0141] While specific embodiments have been disclosed herein, various changes and modifications may be made without departing from the scope of the invention. These embodiments are to be considered illustrative in all respects and not restrictive, and all variations falling within the meaning and equivalents of the appended claims are intended to be included therein.
