Description

[0001] The invention relates to a method for disassembling a control element of an operating device from a receiving device of the operating device. A further aspect of the invention relates to a method for installing a control element of an operating device into a receiving device of the operating device. A further aspect of the invention relates to an operating device, a cover with an operating device, and a motor vehicle with an operating device.

[0002] For vehicle controls, such as a volume control, the controls are attached from below to a panel on the vehicle's center console. For example, the controls are clipped onto the panel from below. This requires first removing and then reinstalling the center console panel.

[0003] German patent DE 10 2012 109 607 A1 describes a possible installation method for a touch-sensitive rotary knob switch. The rotary knob switch comprises a housing with a top cover and a bottom cover. When the housing is inserted, a multitude of elastic locking lugs with ratchets are spaced apart around the outer circumference of the top cover. The housing is inserted into a positioning hole at a predetermined location. The locking lugs secure the housing in place, preventing water from penetrating the ground from the outside via the outer circumference of the top cover.

[0004] German patent application DE 20 2004 006 783 U1 describes a rotary switch for installation in the instrument panel of a motor vehicle. The rotary switch comprises a switch housing, an actuating shaft rotatably arranged within the switch housing, a rotary knob mounted on one end of the actuating shaft, and an annular cover surrounding the rotary knob and detachably attached to the switch housing. The cover is connected to the switch housing by a detent mechanism that can be released by relative rotation between the cover and the switch housing. Furthermore, the rotary knob is axially displaceable in a specific rotational position and can thus be coupled to the cover in a rotationally fixed manner.

[0005] The disadvantage of using such control units is that the necessary steps for their installation and / or removal are particularly complex. Furthermore, special tools are usually required for installation and / or removal. Replacing a control unit attached to a cover plate is also time-consuming and prone to damage during servicing due to the removal and reinstallation of the cover plate.

[0006] EP 2 955 735 A1 describes a switching device. The switching device comprises an operating unit, a switching unit, and a rotary drive section. The operating unit and the switching unit can be connected and disconnected. The operating unit and the switching unit are coupled via the rotary drive section. To connect the operating unit and the switching unit, the operating unit is aligned with the switching unit and inserted or pressed in. As the operating unit is pressed into the switching unit, a projection of the rotary drive section engages in the engagement groove of the operating unit through a rotational movement.

[0007] German patent DE 10 2020 124 463 A1 describes an operating device. The operating device comprises a rotary knob arranged on a receptacle and a housing part. A locking element and a counter-locking element are arranged between the receptacle located in the housing part and the housing part itself. The receptacle is held on the housing part by the locking elements and the counter-locking element. The locking element is designed as a spring element and the counter-locking element as a tab.

[0008] The invention is based on the objective of providing a method for disassembling and assembling a control element of an operating device, which is designed to be particularly simple and reliable.

[0009] The problem is solved by the subject matter of the independent patent claims. Advantageous embodiments of the invention are described in the dependent patent claims, the description, and the figures.

[0010] One aspect of the invention relates to a method for disassembling or removing a control element of an operating device from a receiving device of the operating device. The control element comprises a housing, a control element, and a rotary ring. In particular, the control element is an operating device comprising the housing, the control element, and the rotary ring. The control element or operating device is, for example, configured as a volume control.

[0011] The control element can be a button or a knob. Alternatively, it can be a capacitive control element. The capacitive control element can have a surface that includes a sensor film. The control element can have a cylindrical shape.

[0012] The rotary ring surrounds the control element. In other words, the rotary ring encloses or frames the control element. Specifically, the rotary ring is designed as an annular element that surrounds the control element. In particular, the rotary ring is arranged on an outer circumferential surface of the control element. The rotary ring can be coupled and / or connected to the control element.

[0013] A function can be triggered by actuating the control element while operating the control device, such as by applying a predetermined pressure force to the control element or by touching its operating surface. Similarly, a function can be triggered by actuating the rotary ring while operating the control device, such as by rotating the rotary ring, particularly clockwise and / or counterclockwise. If the control element or control device is designed, for example, as a volume control, the volume can be adjusted by rotating the rotary ring. The rotary ring can be moved relative to the control element. In other words, the rotary ring can perform a relative movement or a rotation relative to the control element.

[0014] The control element and the rotary ring are arranged on a first end face of the housing, with the housing being coupled to the rotary ring. The control element can also be coupled to the housing. For example, the housing can contain a bearing for the rotary ring and / or the control element. In particular, the rotary ring can be coupled to a rotatable actuating shaft arranged in the housing.

[0015] In this method, a pressure force is applied to the operating element in one process step, whereby the pressure force blocks any rotational movement of the rotating ring relative to the operating element. In other words, the rotating ring can be designed such that it can be locked during disassembly by pressing down on the operating element. In other words, the rotating ring can only be locked when the operating element is pressed. When the operating element is pressed with a predetermined pressure force, the rotating ring can no longer be rotated around the operating element. As long as no pressure force is applied to the operating element, the rotating ring is preferably rotatable around the operating element or can rotate relative to the operating element.In particular, the pressure force, or a predetermined force, is exerted perpendicularly on a control surface or operating area of ​​the control element, preferably in the direction of a longitudinal axis of the control device. The pressure force displaces the control element axially or linearly, thereby blocking the rotational movement of the rotary ring relative to the control element. The pressure force also displaces or pushes the control element axially in the direction of the first end face of the housing. In particular, the axial displacement of the control element allows the rotary ring to be coupled to the control element in a rotationally fixed manner.

[0016] The pressure force displaces the housing, which is in an installation position and at least partially arranged in the receiving device, particularly axially, from its installation position towards a contact surface of the receiving device opposite a receiving opening of the receiving device. Before the pressure force is applied, the housing of the control element is located at least partially, i.e., completely or partially, in the receiving device in its installation position. "Installation position" means, in particular, that the control element, preferably its housing, can be coupled to the receiving device, is connected to the receiving device by a mechanism, or is locked in the receiving device. When the pressure force is applied to the control element, the housing or the control element is preferably first pushed further into the receiving device, particularly axially.In this process, the housing preferably moves away from the receiving opening towards a contact surface of the receiving device. For example, the contact surface can form a base or a bottom surface of the receiving device.

[0017] In a further process step, a rotational movement, particularly counterclockwise, is applied to the rotating ring, thereby rotating the control element such that the housing is dislodged from its installation position. Preferably, the housing and the control element rotate along with the locked rotating ring, particularly automatically. In other words, if the rotating ring is locked by the pressure force on the control element and the rotating ring is turned, the entire control element, i.e., in particular the housing, the control element, and the rotating ring, can be rotated.

[0018] Applying the pressure force to the control element and the rotary movement are preferably performed simultaneously or sequentially. In particular, the control element remains pressed during the rotary movement. When applying the rotary movement and / or the pressure force, the housing is moved relative to an inner circumferential surface of the receiving device. A predetermined pressure is preferably applied to the control element, and simultaneously the locking ring is rotated, particularly counterclockwise. The rotary movement is performed about a rotational axis of the control device. The receiving device is not moved or rotated.

[0019] In a further process step, the pressing force is released and the housing is moved, in particular automatically, to the receiving opening of the receiving device for the purpose of removing the control element. Specifically, the housing or the control element can be guided vertically upwards, i.e., in the direction of the longitudinal axis of the operating device against the direction of the pressing force, out of the receiving device. In particular, after the pressing force is released, especially after the control element and / or the rotating ring is released, the housing can be moved to the receiving opening. The housing or the control element is preferably moved or pulled axially out of the receiving device.

[0020] For example, the control element or the rotary ring is designed such that the rotary ring can be locked during disassembly by pressing down on the control element, so that the control element can be unlocked from the receiving device, particularly from its installed position, without tools when rotated, especially by rotating the rotary ring. In particular, the rotary ring is only locked when the control element is pressed. The control element can then be rotated out, particularly from its installed position, using the rotary ring. Preferably, the control element can be unlocked by pressing on the control element and simultaneously by rotating the (in particular, locked) rotary ring, particularly within the receiving device. In particular, the rotary ring can be rotated without pressing on the control panel or the control element. This ensures that no user of the control device or control element can unlock the control element "accidentally".

[0021] This offers the advantage that the control unit can be removed from the mounting device in a particularly simple and reliable manner. Furthermore, this method prevents damage to the control unit. In addition, disassembly takes very little time. Moreover, no special tools are required for disassembly. This results in cost savings.

[0022] The invention also includes embodiments that offer additional advantages.

[0023] One embodiment provides that the rotary ring has a first profile on an inner circumferential surface. In other words, the rotary ring has a first profile on an inner circumferential surface. The inner circumferential surface is preferably located opposite an outer circumferential surface of the rotary ring or facing the control element. The first profile preferably extends completely in a circumferential direction along the inner circumferential surface. Furthermore, the control element has a second profile on an underside facing the housing and / or on an outer circumferential surface. The second profile extends, in particular, along an outer radius of the control element on the underside of the control element and / or in a circumferential direction along the outer circumferential surface of the control element. When a pressure force is applied to the control element, the second profile engages with the first profile to block the rotational movement of the rotary ring relative to the control element.Preferably, the second profile of the control element engages with the first profile of the rotary ring when a predetermined pressure force is applied to the control element. In particular, a predetermined pressure force is applied to the control element perpendicular to the receiving opening. The blocked rotational movement of the rotary ring relative to the control element is achieved, in particular, by the pressure force displacing or moving the control element, especially in the direction of a longitudinal axis of the operating device, thus causing the second profile of the control element to engage with the first profile of the rotary ring. This preferably results in the rotary ring and the control element being positively locked and / or force-locked and / or rotationally fixed to each other.

[0024] Another aspect of the invention relates to a method for installing or mounting a control element of an operating device into a receiving device of the operating device, wherein the control element comprises a housing, a control element, and a rotating ring, the rotating ring surrounding the control element, the control element and the rotating ring being arranged on a first end face of the housing, and the housing being coupled to the rotating ring. In a method step, the housing of the control element is arranged on a receiving opening of the receiving device. In particular, the housing is positioned in the receiving opening such that the control element or the housing can be inserted into the receiving device. In particular, the housing is positioned on or in the receiving opening of the receiving device with a second end face opposite the first end face.In particular, the control unit or the housing is inserted into the receiving device via the receiving opening, especially from above.

[0025] In a further process step, a pressure force is exerted or applied to the operating element of the control device, whereby the pressure force displaces the housing through the receiving opening in the direction of a contact surface of the receiving device opposite the receiving opening. When the pressure force is exerted on the operating element, the housing or the operating element is preferably inserted into the receiving device, particularly axially. In this process, the housing preferably moves away from the receiving opening in the direction of the contact surface of the receiving device. For example, the contact surface can form a base or a bottom surface of the receiving device.

[0026] Furthermore, the housing is at least partially received in the receiving device. In particular, pressing the control unit into the receiving device places the housing at least partially, i.e., completely or partially, within the receiving device.

[0027] In a further process step, the control element is rotated, particularly clockwise, thereby moving the housing within the receiving device towards an installation position. The control element can perform this rotation automatically. The application of the pressure force and the rotation are preferably performed simultaneously and sequentially. During the execution or application of the rotation, the control element and the housing rotate together, particularly due to the positive locking of the rotating ring and the control element and the coupling of the rotating ring to the housing. During the execution of the rotation and / or the application of the pressure force, the housing is moved relative to the inner circumferential surface of the receiving device. The receiving device itself is not moved or rotated. The rotation occurs, in particular, about a rotational axis or a longitudinal axis of the control device.

[0028] In a further process step, the pressure is released and the housing or control element is moved, particularly automatically, into the installation position in the receiving device. Preferably, after the pressure is released, particularly after the control element or operating element and / or the rotary ring is released, the housing, particularly the control element, can slide or glide into the installation position. In the installation position, the control element, particularly the housing, can then lock into place. In the installation position, the control element, preferably the housing of the control element, can be coupled to the receiving device or connected to the receiving device by a mechanism, or locked into the receiving device. Particularly preferably, installation is achieved by applying a predetermined downward pressure to the control element until the control element rotates itself into the correct position and locks into place.

[0029] This offers the advantage that the control unit can be mounted into the mounting device in a particularly simple and reliable manner. Furthermore, this method prevents damage to the control unit. Assembly time is also significantly reduced, and no special tools are required. This results in cost savings.

[0030] According to the invention, during assembly, the pressure applied to the control element blocks the rotary ring from rotating relative to the control element. When the control element is pressed, the rotary ring can no longer rotate around it. This blocked rotation of the rotary ring relative to the control element is achieved, in particular, by the pressure force displacing or moving the control element, especially along a longitudinal axis of the operating device, causing the second profile of the control element to engage with the first profile of the rotary ring. This preferably results in a positive-locking, force-locking, and / or rotationally fixed coupling or connection between the rotary ring and the control element.

[0031] If, for example, the control unit or the housing does not rotate into the installation position during assembly, particularly automatically, it may be additionally or alternatively provided that a rotational movement of the blocked rotary ring of the control device, particularly clockwise, is then exerted or carried out during assembly, whereby the housing is rotated in such a way that the housing is guided into the installation position.

[0032] The disassembly and / or assembly of the control unit and / or the application of the pressure force and / or the execution of the rotary movement can be performed by a user and / or by a robot arm of a robot.

[0033] Another aspect of the invention relates to an operating device for a motor vehicle. The operating device comprises a control element, which includes a control component, a rotary ring, and a housing. The operating device or the control component can, for example, be configured as a volume control. The control component can be configured as a button or a knob. Alternatively, the control component can be configured as a capacitive control component. The capacitive control component can have a user surface comprising a sensor film. The control component can have a cylindrical shape.

[0034] The rotary ring surrounds the control element. In other words, the rotary ring encloses or frames the control element. Specifically, the rotary ring is designed as an annular element that surrounds the control element. In particular, the rotary ring is arranged on an outer circumferential surface of the control element. The rotary ring can be coupled and / or connected to the control element.

[0035] A function can be triggered by actuating the control element, such as by applying a predetermined pressure force to the control element or by touching its surface. Similarly, a function can be triggered by actuating the rotary ring, such as by rotating it, particularly clockwise and / or counterclockwise. If the control device or operating element is designed as a volume control, for example, the volume can be adjusted by rotating the rotary ring. The rotary ring can be moved relative to the control element. In other words, the rotary ring can perform a relative movement to the control element.

[0036] The housing can have a cylindrical shape. In other words, the housing can have the shape of a cylinder, in particular a hollow cylinder. The control element and the rotary ring are arranged on a first end face of the housing, with the housing being coupled to the rotary ring. Additionally, the control element can be coupled to the housing. For example, a bearing for the rotary ring and / or for the control element can be arranged in the housing. In particular, the rotary ring can be coupled to a rotatable actuating shaft arranged in the housing.

[0037] At least two locking lugs are arranged at a predetermined distance, particularly at a uniform distance, from one another on a lateral surface of the housing. In other words, the at least two locking lugs are spaced apart from one another on an outer circumferential surface of the housing. The lateral surface extends, in particular, between the first end face and a second end face of the housing. "End face" refers, in particular, to an end face, base face, or top face of the housing, especially a cylindrical housing. The respective end face extends, in particular, perpendicular to a longitudinal axis or axis of rotation of the housing or the operating device. The axis of rotation extends, in particular, perpendicular to the operating surface and / or runs centrally through the operating device or operating surface.The operating device, in particular the rotary ring and / or the control element and / or the housing, is preferably rotatable about the axis of rotation.

[0038] Preferably, the at least two locking lugs are arranged at an angular distance of 180° from each other. Preferably, three locking lugs can be arranged on the lateral surface. The three locking lugs can be arranged at an angular distance of 120° from each other. "Locking lug" refers in particular to a projection, a protruding element, or a raised feature on the lateral surface. In particular, the at least two locking lugs are attached or fixed to the lateral surface. Furthermore, the at least two locking lugs are preferably arranged on the same circular path on the lateral surface or the outer circumferential surface, or on the same plane or at the same height on the lateral surface or the outer circumferential surface, or centrally between the first end face and the second end face, or at a predetermined distance from the respective end face.

[0039] Furthermore, the operating device includes a receiving device configured to at least partially receive the housing. In other words, the receiving device can enclose the housing at least partially, i.e., completely or partially. Preferably, the housing projects out of the receiving device with a portion or area, particularly at or with the first end face. Preferably, the housing is arranged in the receiving device with its second end face opposite the first end face, particularly in the direction of the longitudinal axis of the operating device.

[0040] The receiving device has at least two guide grooves on an inner circumferential surface, each guide groove being configured to receive a locking lug. In particular, the receiving device has at least two guide grooves on an inner surface or on a surface facing the outer surface of the housing. "Guide groove" refers in particular to a groove or recess extending along the inner surface of the receiving device. In particular, each guide groove is associated with a locking lug. The guide grooves extend axially, in particular in the direction of a longitudinal axis of the operating device, from a receiving opening of the receiving device towards a contact surface of the receiving device opposite the receiving opening and transition into an arcuate or semicircular section. "Contact surface" refers in particular to a base of the receiving device.

[0041] In an installed position of the housing in the receiving device, the housing is at least partially received in the receiving device, and a locking lug is arranged in an engagement position within the guide groove. "Installed position" means, in particular, that the housing can be coupled to the receiving device or is connected by a mechanism that includes, in particular, the guide grooves and the locking lugs. The engagement position is located, in particular, at the end of the arcuate or semicircular section of the guide groove. Preferably, the locking lugs engage with the guide grooves in the manner of a latching mechanism, more preferably in the manner of a bayonet fitting.

[0042] This results in the advantage that the operating device is particularly simple and robust in design. Furthermore, damage and working time during the assembly and / or disassembly of the operating unit into its installation position in the mounting device are reduced. Moreover, no special tools are required for assembly and / or disassembly.

[0043] One embodiment provides that the operating device or control element comprises at least two spring elements, in particular three spring elements, wherein the spring elements are arranged on a second end face of the housing opposite the first end face, particularly in the direction of a longitudinal axis of the operating device, and wherein the spring elements are configured to hold the locking lugs in their engaged position. In particular, the at least two spring elements generate a counter-pressure in the installation position of the housing in the receiving device, so that the locking lugs are pressed into their engaged position. The spring elements are arranged, in particular, between the second end face of the housing and the contact surface of the receiving device. This has the advantage that the housing or the control element is held in the receiving device in a particularly simple and reliable manner.

[0044] Preferably, the at least two spring elements are arranged at a predetermined distance, particularly a uniform distance, from each other, especially along an outer circumference of the housing, on the second end face. For example, the at least two spring elements are arranged at an angular distance of 180° from each other on the second end face. If the operating device comprises, for example, three spring elements, these can be arranged at an angular distance of 120° from each other.

[0045] According to an advantageous embodiment, the at least two spring elements are designed as arms formed from an elastic material, wherein the arms are oriented at a predetermined angle, in particular 45°, to the second end face. In other words, the arms are arranged or oriented at a predetermined angle, in particular 45°, inclined to the second end face. "Arm" refers in particular to a lever or a mechanical link or element. Preferably, the arms are made of plastic, in particular an elastic plastic.

[0046] The receiving device preferably has a contact surface facing the second end face of the housing, with the at least two spring elements pressing against this contact surface in the installed position. In particular, the at least two spring elements are arranged in the receiving device with one end against the contact surface and the other end against the second end face of the housing when the housing is installed. The at least two spring elements are preferably arranged between the second end face of the housing and the contact surface of the receiving device. Preferably, in the installed position of the housing or the control unit, the spring elements press the control unit or the housing axially in a vertical direction or in the direction of a longitudinal or rotational axis of the control unit.In particular, the housing or control unit is prevented from slipping out of the mounting device by anchoring the locking lugs in the engaged position. In the installed position, the at least two spring elements are under tension. Preferably, the angle at which the spring elements are inclined relative to the second end face is less than 45° in the housing's installed position in the mounting device. This offers the advantage of holding the housing in the mounting device in a particularly simple and reliable manner.

[0047] Advantageously, the rotary ring has a first profile on an inner circumferential surface. In other words, the rotary ring has a first profile on an inner circumferential surface. The inner circumferential surface is preferably arranged opposite an outer circumferential surface of the rotary ring or facing the operating element. The first profile preferably extends completely in a circumferential direction along the inner circumferential surface. For example, the first profile can be designed as a gear profile, a zigzag profile, or a wave profile. Furthermore, the operating element has a second profile on an underside facing the housing and / or on an outer circumferential surface. The second profile extends, in particular, along an outer radius of the operating element on the underside of the operating element and / or in a circumferential direction along the outer circumferential surface.For example, the second profile can be configured as a gear profile, a zigzag profile, or a wave profile. Furthermore, the second profile can engage with the first profile, particularly to block rotation of the rotary ring relative to the control element. Preferably, the first and second profiles are identical or congruent to each other. If, for example, the first and second profiles are configured as gear profiles, the teeth of the second gear profile of the control element can engage or be inserted between the teeth of the first gear profile of the rotary ring. In particular, the first gear profile and the second gear profile can mesh or interlock. Preferably, the second profile of the control element engages with the first profile of the rotary ring when a predetermined pressure force is applied to the control element.

[0048] Another embodiment provides that the rotating ring has a rib on an inner circumferential surface, which extends in a ring-like fashion along the inner circumferential surface. In other words, the rotating ring has a rib on an inner circumferential surface, which is preferably located opposite an outer circumferential surface of the rotating ring or facing the operating element, and which extends completely in a circumferential direction along the inner circumferential surface. In particular, the rib is arranged between the first end face of the housing and the operating element. The rib has the first profile on its upper surface, which faces the operating element. The upper surface of the rib preferably extends perpendicular to the inner circumferential surface of the rotating ring.

[0049] In the following, a specific embodiment of the method for mounting the control element of an operating device into the receiving device of the operating device and a specific embodiment of the method for dismantling the control element of an operating device from the receiving device of the operating device will be discussed in more detail by way of example.

[0050] In the method for mounting the control element of the operating device into the receiving device's receiving unit, the housing can be positioned at the receiving opening of the receiving unit and the at least two locking lugs can be arranged in a single process step, each in a guide groove of the receiving unit. In particular, the housing is positioned in the receiving opening such that the locking lugs can be inserted into a guide groove. Specifically, the housing is inserted into the receiving unit through the receiving opening, particularly from above, and the locking lugs are brought into position on the guide grooves.

[0051] A pressure force is then applied to the operating element of the control device. In particular, a predetermined pressure force is applied to the operating element perpendicular to the receiving opening. This pressure force blocks the rotational movement of the rotary ring relative to the operating element. When pressure is applied to the operating element, the rotary ring cannot be rotated around it. The blocked rotational movement of the rotary ring relative to the operating element is achieved, in particular, by the pressure force displacing or moving the operating element, especially along a longitudinal axis of the control device, thus causing the second profile of the operating element to engage with the first profile of the rotary ring. This preferably results in a positive-locking coupling or connection between the rotary ring and the operating element.

[0052] The pressure force allows the locking lugs in the guide groove to be displaced towards a contact surface opposite the receiving opening. Specifically, the locking lugs are displaced axially within the guide groove. In other words, the locking lugs, guided in the guide grooves, can be pressed into the receiving device, particularly towards the contact surface.

[0053] In a further process step, a rotary movement, particularly clockwise, can be applied to the rotating ring of the operating device, thereby rotating the housing such that the locking lugs are guided into a locking position. The application of the pressure force and the rotary movement are preferably performed simultaneously and sequentially. When the rotary movement is applied to the rotating ring, the operating element and the housing rotate together, particularly due to the positive locking of the rotating ring and the operating element and the coupling of the rotating ring to the housing. When the rotary movement and / or the pressure force is applied, the housing is moved relative to the inner circumferential surface of the receiving device. The receiving device itself is not moved or rotated. The rotary movement occurs, in particular, about the axis of rotation of the operating device.

[0054] When a pressing force is applied, the locking lugs are preferably displaced in the axial section of the guide grooves. When a rotational movement is applied, the locking lugs are transferred, in particular, from the axial section of the guide grooves to the semicircular or arcuate section of the guide groove.

[0055] In a further process step, the pressure force can be released, and the locking lugs can be moved, particularly automatically, within the guide groove into the locking position. Specifically, after the pressure force is released, especially after the operating element and / or the rotary ring is released, the locking lugs can slide into the locking position. The movement of the locking lugs into the locking position is effected, in particular, by the spring elements, which apply a pressure force or counter-pressure, especially in the direction of the receiving opening, to the housing. When the pressure force is applied to the operating element, the spring elements can be tensioned and exert a counter-pressure. This counter-pressure allows the locking lugs to be pressed into their locking position in the guide groove.

[0056] In the method for disassembling the control element of the operating device into the receiving device of the operating device, a pressure force can be applied to the control element in one process step, whereby the pressure force blocks any rotational movement of the rotary ring relative to the control element. The blocked rotational movement of the rotary ring relative to the control element is achieved in particular by the pressure force displacing or moving the control element, especially in the direction of a longitudinal axis of the operating device, and thus causing the second profile of the control element to engage with the first profile of the rotary ring. This preferably results in a positive-locking coupling or connection between the rotary ring and the control element.

[0057] In a further process step, a rotary movement, particularly counterclockwise, is applied to the rotating ring. Preferably, the housing and the operating element rotate with the rotating ring, particularly automatically. The application of the pressure force to the operating element and the rotary movement are preferably performed simultaneously or sequentially. During the application of the rotary movement and / or the pressure force, the housing or the operating element is moved relative to the inner circumferential surface of the receiving device. The receiving device is not moved or rotated. The rotary movement is performed, in particular, about a rotational axis of the operating device.

[0058] The pressure force allows the locking lugs within the guide grooves to be moved or displaced from their engaged position, particularly axially, towards a contact surface opposite the receiving opening. The rotational movement allows the locking lugs to be moved or guided around a rotational axis of the operating device from their engaged position within the guide grooves. In other words, when the rotary movement of the rotating ring is applied, the housing or operating element is rotated such that the locking lugs are moved or displaced from their engaged position within the guide grooves. When the pressure force and the rotational movement are applied, the locking lugs are preferably moved or guided in the semicircular or arcuate section of the guide grooves towards the axial section of the guide grooves.

[0059] During disassembly, pressure is applied to the operating element, and simultaneously the locking ring is rotated, preferably counterclockwise. This allows the locking tabs to be pushed downwards, i.e., in the direction of the longitudinal axis in the direction of the pressure force, and simultaneously out of their locked position, particularly counterclockwise.

[0060] In a further process step, the pressing force is released and the locking lugs within the guide groove are moved, particularly axially towards the receiving opening, out of the receiving device, especially automatically. Specifically, the locking lugs can be guided vertically upwards, i.e., in the direction of the longitudinal axis opposite to the direction of the pressing force, out of the receiving device. Specifically, after the pressing force is released, particularly after the operating element and / or the rotary ring is released, the locking lugs can be moved towards the receiving opening.

[0061] The predetermined pressure force or a value of the pressure force exerted on the control element during assembly and / or disassembly is preferably greater than a pressure force or a value of a pressure force exerted on the control element when the control element is actuated.

[0062] When mounting the control unit of the operating device into the receiving device, the housing, together with the control element and rotating ring located on the first end face of the housing, is positioned in the receiving device. When removing the housing or the control unit of the operating device from the receiving device, the housing, together with the control element and rotating ring located on the first end face of the housing, is removed from the receiving device.

[0070] Exemplary embodiments of the invention are described below. The single figure, Fig., shows an operating device 12 arranged on a panel 10.

[0071] The exemplary embodiments described below are preferred embodiments of the invention. In these exemplary embodiments, the described components each represent individual features of the invention, which can be considered independently of one another and each further develops the invention independently. Therefore, the disclosure is intended to include combinations of features of the embodiments other than those shown. Furthermore, the described embodiments can also be supplemented by further features of the invention already described.

[0072] In the figure, identical reference symbols denote functionally equivalent elements.

[0073] Figure 12 shows an operating device 12 arranged or mounted on a panel 10 for a motor vehicle. The operating device 12 is, for example, designed as a volume control. The operating device 12 comprises a control unit 13. The control unit 13 has a control element 14. The control element 14 has a cylindrical shape. The control element 14 is, for example, designed as a knob or a button. The control element 14 has a user interface 16, in particular a sensitive user interface 16. The user interface 16 has, for example, a sensor film, in particular a capacitive one. The user interface 16 is divided into various operable areas, which are identified by different symbols. By performing an action on a respective area, such as pressing or touching the respective area by a user, a function, such as a device function, can be controlled.The control element 14 is movable or displaceable in the direction of a longitudinal or principal axis of the control device 12. In other words, the control element 14 is axially displaceable. When a pressure force is applied to the control element 14, it can be displaced or moved in the direction of the longitudinal axis of the control device 12. If the control element 14 is released after being subjected to a pressure force, it can move back to its original position in the opposite direction to the pressure force.

[0074] Furthermore, the control element 13 includes a rotary ring 18. The rotary ring 18 encompasses or surrounds the control element 14. In other words, the rotary ring 18 can enclose the control element 14. The rotary ring 18 is arranged along an outer circumferential surface of the control element 14. The rotary ring 18 has an annular shape or the shape of a hollow cylinder. An inner surface of the rotary ring 18 faces the control element 14. In particular, the rotary ring 18 can be moved relative to the control element 14. The rotary ring 18 can be rotated, in particular about a rotational or longitudinal axis of the control device 12. The rotary ring 18 can be rotated around the control element 14, especially when no pressure force is exerted on the control element 14. If the control device 12 or the control element 13 is designed, for example, as a volume control, the rotary ring 18 can be used to adjust the volume.Turning the rotating ring 18 clockwise increases the volume. Turning the rotating ring 18 counterclockwise decreases the volume.

[0075] Furthermore, the control unit 13 has a housing 20. The rotary ring 18 and / or the control element 14 is coupled or connected to the housing 20. For example, the housing 20 may contain a bearing for the rotary ring 18 and / or the control element 14. The rotary ring 18 and / or the control element 14 are arranged on a first end face 22 of the housing 20. The housing 20 has a cylindrical shape. Preferably, the housing 20 has the shape of a hollow cylinder. The housing 20 comprises the first end face 22 and, particularly in the direction of a principal extension direction or longitudinal axis of the control device 12, a second end face 24 opposite the first end face 22. A lateral surface 26 of the housing 20 extends between the first end face 22 and the second end face 24.

[0076] As can be seen in the figure, a locking lug 28 is arranged on the outer surface 26 of the housing 20. In other words, a locking lug 28 is arranged on an outer circumferential surface of the housing 20. The operating device 12 has at least two locking lugs 28, preferably three or four. The locking lugs 28 are preferably arranged centrally between the first end face 22 and the second end face 24 on the outer surface 26. The at least two locking lugs 28 are arranged at a predetermined distance from each other. For example, the two locking lugs 28 can be arranged at an angular distance of 180° from each other on the outer circumferential surface or the outer surface 26. If the operating device 12 has, for example, three locking lugs 28, the three locking lugs can be arranged at an angular distance of 120° from each other.The locking lugs 28 are arranged at the same height or on the same radius or along the same circle on the outer circumferential surface or lateral surface 26.

[0077] Furthermore, the operating device 12 comprises a receiving device 30. The receiving device 30 is configured to receive the housing 20 of the control element 13 at least partially, i.e., completely or partially. The housing 20 is, particularly in an installation position, at least partially received or arranged in an interior or receiving area of ​​the receiving device 30. The shape of the interior or receiving area of ​​the receiving device 30 is adapted to a shape of the housing 20. In the figure, the housing 20 or the control element 13 is located in an installation position within the receiving device 30. The housing 20 can be inserted into the receiving device 30 via a receiving opening 31. The receiving device 30 has a guide groove 32 on a surface facing the outer surface 26 of the housing 20. In particular, the housing 20 has a guide groove 32 on an inner circumferential surface or inner outer surface. In the figureOnly one guide groove 32 is shown. The receiving device 30 comprises at least two guide grooves 32. The two guide grooves 32 are identical or the same. Preferably, the receiving device 30 has three guide grooves 32. In particular, a number of the guide grooves 32 correspond to a number of the locking lugs 28. The guide grooves 32 are configured to receive the locking lugs 28. The guide grooves 32 are arranged at a predetermined distance, in particular a uniform distance, from one another on the inner circumferential surface of the receiving device 30. For example, the two guide grooves 32 can be arranged at an angular distance of 180° from one another on the surface or inner circumferential surface. If the operating device 12 has, for example, three guide grooves 32, the three guide grooves can be arranged at an angular distance of 120° from one another.

[0078] As can be seen in the figure, the guide groove 32 has a J-shape. The guide groove 32 extends axially in a principal direction of extension, or in the direction of a longitudinal axis, or in the direction of a rotational axis of the operating device 12. In other words, the guide groove 32 has an axial section. The guide groove 32, and in particular the axial section, extends from the receiving opening 31 of the receiving device 30. The axial section transitions into a U-shaped, semicircular, or arcuate section. In the figure, the locking lugs 28 are in a locking position 33. The locking position 33 is located at the end or at an end region of the guide groove 32. The locking position 33 is arranged at the end of the arcuate section of the guide groove 32.

[0079] Furthermore, the operating device 12 or the control element 13 comprises at least two, preferably three or four, spring elements 34. The spring elements 34 are arranged or attached to the second end face 24 of the housing 20. The spring elements 34 are arranged at a predetermined distance from each other on the second end face 24 of the housing 20. The spring elements 34 are arranged along an outer circumference or radius on the second end face 24. For example, the two spring elements 34 can be arranged at an angular distance of 180° from each other on the second end face 24. If the operating device 12 has, for example, three spring elements 34, the three spring elements 34 can be arranged at an angular distance of 120° from each other. The spring elements 34 are preferably made of an elastic material, for example, an elastic plastic. The spring elements 34 are designed as arms.The spring elements 34, each designed as an arm, are arranged at a predetermined angle to the second end face 24 of the housing 20. For example, the spring elements 34 are arranged at an angle of 45° to the second end face 24 of the housing 20 or aligned at an angle of 45° to the second end face 24. In particular, the angle is 45° when the spring elements 34 are not tensioned. In the figure, the housing 20 is in an installation position in the receiving device 30. In the installation position, the locking lugs 28 are in the locking position 33 and the spring elements 34 are tensioned. In the installation position, a compressive force acts on the spring elements 34 in the direction of the axis of rotation, in the direction of a longitudinal axis, or in a principal extension direction of the operating device 12, in particular from the first end face 22 towards the second end face 24.To keep the locking lugs 28 in the locked position, the spring elements 34 exert a counter-pressure. The counter-pressure acts in the direction of the axis of rotation, or in the direction of a longitudinal axis, or in a main extension direction of the operating device 12, in particular from the second end face 24 towards the first end face 22.

[0080] Furthermore, the operating device 12 or the control unit 13 includes a connector 38. The connector 38 allows the operating device 12 or the control unit 13 to be supplied with electrical energy or connected to the electrical system of a motor vehicle. The connector 38 is located on an underside 40 of the receiving device 30. The underside 40 is located opposite the receiving opening 31, through which the housing 20 can be inserted into the receiving device 30.

[0081] In the figure, the housing 20 or the control element 13 is located in the installation position in the receiving device 30. The receiving device 30 has a contact surface 36 facing the second end face 24 of the housing 20. In the installation position, the spring elements 34 press against the contact surface 36. In the installation position, the spring elements 34 are arranged on the contact surface 36. In particular, in the installation position, the spring elements 34 are tensioned between the second end face 24 and the contact surface 36.

[0082] In the figure, the housing 20 with the control element 14 and the rotary ring 18 attached to it is located in its installed position in the receiving device 30. The receiving device 30 is arranged or attached to a rear side 42 of the cover 10. The control element 14 and the rotary ring 18 are arranged on a front side 44 of the cover 10 opposite the rear side 42. The cover 10 can be a cover 10 for a motor vehicle. The cover 10 can be mounted in an interior of the motor vehicle, in particular on a center console of the motor vehicle. The front side 44 of the cover 10 then forms a visible side of the cover 10.

[0083] The aperture 10 has an aperture opening 46. The aperture opening 46 is round. The receiving device 30 is arranged on the rear side 42 of the aperture 10 such that the aperture opening 46 and the receiving opening 31 of the receiving device 30 are aligned. In particular, the dimensions of the receiving opening 31 and the aperture opening 46 are identical. The receiving opening 31 is also round. In particular, the diameters of the receiving opening 31 and the aperture opening 46 are the same.

[0084] The following section describes in more detail the installation and removal of the control unit 13 from the receiving device 30. For mounting the control unit 13, in particular the housing 20 with the operating element 14 and rotary ring 18 attached to it, the housing 20 of the control unit 13 is positioned at the receiving opening 31. Furthermore, the locking lugs 28 are positioned on the guide grooves 32. The locking lugs 28 are positioned on the opening or insertion area of ​​the guide groove 32. The housing 20 is thus positioned so that the locking lugs 28 can be inserted into the guide grooves 32. The housing 20 is guided, in particular perpendicular to the front face 44 of the aperture 10, through the aperture opening 46 and / or positioned at the receiving opening 31 of the receiving device 30.To cause the locking lugs 28 to slide into the guide groove 32, a predetermined pressure or force is applied to the control element 14, in particular perpendicular to the front face 44 of the aperture 10 or perpendicular to the operating surface 16. Simultaneously, the rotary ring 18 is rotated clockwise. As soon as a pressure force is applied to the control element 14, the rotary ring 18 is locked, preventing it from rotating or moving relative to the control element 14. Therefore, if the rotary ring 18 is rotated under pressure, the control element 14, the rotary ring 18, and the housing 20 rotate about a rotational axis of the operating device 12 or about a longitudinal axis of the operating device 12. The pressure force guides the locking lugs 28 and / or the housing 20 axially from the receiving opening 31 toward the contact surface 36 or toward the underside 40 of the receiving device 30.The rotational movement transfers the locking lugs 28 from the axial section into the arcuate section of the guide groove 32 and slides into the locking position 33. In the locking position 33, the spring elements 34 press the locking lugs 28 into the locking position 33.

[0085] To remove the housing 20 from the receiving device 30, a pressure force is again applied to the control element 14, and the rotating ring 18 is turned counterclockwise. The pressure force is applied perpendicular to the front face 44 of the aperture 10 and / or perpendicular to the operating surface 16. The pressure force again blocks the rotating ring 18, preventing it from rotating or moving relative to the control element 14. Therefore, if the rotating ring 18 is rotated under pressure, the control element 14, the rotating ring 18, and the housing 20 rotate about the axis of rotation of the operating device 12 or about a longitudinal axis of the operating device 12. This pushes the locking lugs 28 downwards and simultaneously out of their detent position 33, allowing them to be guided axially upwards again out of the guide groove 32.

[0086] To enable the rotating ring 18 to be locked, the rotating ring 18 has a ridge on its inner surface facing the control element 14. The ridge extends in a ring-like shape along the inner surface of the rotating ring 18. In other words, the ridge is located on an inner circumferential surface of the rotating ring. On an upper surface of the ridge, which faces the control element 14 or is located opposite the operating surface 16, the ridge has a first profile, such as a gear profile or a zigzag profile. The control element 14 has a second profile, such as a gear profile or a zigzag profile, on an underside facing the housing 20, the second profile being capable of engaging with the first profile.

[0087] Overall, the examples show how an operating device can be assembled and / or disassembled from above without tools.

[0088] This mounting system allows a volume control to be installed and / or removed from the center console trim without having to remove and reinstall it. No special tools are required for installation or removal. Installation is achieved by pressing down on the volume control or control unit after connecting the plug until it rotates into the correct position and clicks into place. To remove the control, press down on the control panel or surface and simultaneously turn the locked volume ring counterclockwise until the locking tabs release from their position and the control can be lifted out.The volume control or operating element cannot be accidentally released, as it would return to its detent position without simultaneous rotation of the rotary ring.

[0089] The volume control or operating element includes, in particular, three locking tabs that secure the volume control or operating element in guide grooves of the mounting bracket or receptacle. Once the connector is in place, the volume control is inserted from above into the bracket or receptacle and the three locking tabs are engaged. Then, simply pressing down on the control surface is sufficient. The three locking tabs slide into the guide grooves, and the volume control automatically rotates into position, so that when released, the volume control slides up into the locked position.

[0090] Disassembly is only possible when pressure is applied to the control panel and the locking rotary ring or volume control ring is simultaneously turned counterclockwise. The control unit can be unlocked without tools by pressing and simultaneously turning the rotary ring. Without pressure on the control element, the rotary ring can be turned, preventing the control unit from accidentally unlocking. Only when the control panel is pressed can the rotary ring be locked. Only then can the control unit be unscrewed using the rotary ring. This simultaneously pushes the locking tabs downwards from their locking position to the right or counterclockwise, allowing the control unit to be removed vertically upwards from its holder or mounting device.

[0091] The three to four return springs can generate the counter-pressure.
