Description

Technical Field

[0001] This invention relates to a method for removing an operating unit of an operating device from a receiving device. Another aspect of the invention relates to a method for installing an operating unit of an operating device into a receiving device. Yet another aspect of the invention relates to an operating device, a cover / decorative panel with the operating device, and a motor vehicle with the operating device. Background Technology

[0002] For vehicle control units (such as volume controls), the unit is fixed to the center console from below via a cover. For example, the unit is clamped to the cover from below. Therefore, the center console cover must first be removed and then reinstalled.

[0003] DE 10 2012 109 607 A1 describes an installation scheme for a touch-sensitive rotary switch. The rotary switch includes a housing with a top cover and a bottom cover. When the housing is inserted, a plurality of resilient locking lugs, each having a pawl, are spaced apart on the outer periphery of the top cover. The housing is inserted into a positioning hole at a predetermined location. At this point, the housing can be locked by the locking lugs to prevent water from seeping into the bottom from the outside through the outer periphery of the top cover.

[0004] DE 20 2004 006 783 U1 describes a rotary switch for installation in the dashboard of a motor vehicle. The rotary switch includes a switch housing, an operating shaft rotatably arranged within the switch housing, a knob sleeved on the end of the operating shaft, and an annular cover surrounding the knob and removably secured to the switch housing. The cover is connected to the switch housing via a locking mechanism that can be released by relative rotation between the cover and the switch housing. Furthermore, the knob is axially movable in a specific rotational position, thereby enabling it to be engaged with the cover in a non-rotatable manner.

[0005] The disadvantage of using such operating units is that the procedures required for their installation and / or removal are particularly complex. Furthermore, specialized tools are often required for installation and / or removal. In maintenance situations, replacing the operating unit, which is secured to the cover, is very complicated and prone to damage due to the removal and installation of the cover. Summary of the Invention

[0006] The purpose of this invention is to provide a method for disassembling and installing an operating unit for operating equipment that is particularly simple and reliable in design.

[0007] This objective is achieved through the subject matter of the independent claims. Advantageous improvements of the invention are described in the dependent claims, the description, and the drawings.

[0008] One aspect of the invention relates to a method for disassembling or removing an operating unit of an operating device from a receiving device. The operating unit includes a housing, an operating element, and a rotating ring. In particular, the operating unit is an operating device having a housing, an operating element, and a rotating ring. The operating unit or operating device is, for example, designed as a volume controller.

[0009] The actuating element can be designed as a button or pushbutton. Alternatively, the actuating element can be designed as a capacitive actuating element. A capacitive actuating element can have an actuating surface that includes a sensor membrane. The actuating element can have a cylindrical shape.

[0010] Here, the rotating ring surrounds the operating element. In other words, the rotating ring encloses or frames the operating element. In particular, the rotating ring is designed as an annular element surrounding the operating element. Specifically, the rotating ring is arranged on the outer peripheral surface of the operating element. The rotating ring can be coupled to and / or connected to the operating element.

[0011] A function can be triggered by manipulating the operating element when the operating device is operated, such as applying a predetermined pressing pressure to the operating element or touching the operating surface of the operating element. Similarly, a function can be triggered by manipulating a rotating ring when the operating device is operated, such as applying rotation to the rotating ring, especially clockwise and / or counterclockwise rotation. For example, if the operating unit or operating device is designed as a volume controller, the volume is adjusted by rotating the rotating ring when the volume controller is operated. In particular, the rotating ring can be moved relative to the operating element. In other words, the rotating ring can perform rotation or relative movement of the actuator relative to the operating element.

[0012] An operating element and a rotating ring are arranged at a first end of the housing, wherein the housing is connected to the rotating ring. Alternatively, the operating element may also be connected to the housing. For example, support components for the rotating ring and / or the operating element may be arranged within the housing. In particular, the rotating ring may be connected to a rotatable operating shaft arranged within the housing.

[0013] In this method, in one step, a pressing force is applied to the operating element, wherein the pressing force acting on the operating element prevents the rotating ring from rotating relative to the operating element. In other words, the rotating ring can be designed to be locked by pressing down on the operating element during disassembly. In other words, the rotating ring can be locked when the operating element is pressed. If the operating element is pressed with a predetermined pressing force, the rotating ring can no longer rotate about the operating element. Preferably, the rotating ring can rotate about the operating element, or can rotate relative to the operating element, as long as no pressing force is applied to it. In particular, the pressing force or predetermined force or pressure is applied perpendicularly to the operating surface or operating area of ​​the operating element, preferably along the longitudinal axis of the operating device. By pressing force, especially by causing axial or linear movement of the operating element, the rotating ring cannot rotate relative to the operating element. By pressing force, especially by pushing or pressing the operating element axially upwards towards or against the first end face of the housing. In particular, the rotating ring can be connected to the operating element in a manner that prevents relative rotation by axial movement of the operating element.

[0014] By applying pressure, the housing, which is in the mounting position and at least partially arranged in the receiving device—especially axially—moves from the mounting position toward the abutment / support surface of the receiving device opposite the receiving opening of the receiving device. Specifically, before applying pressure, the housing of the operating unit is at least partially, i.e., completely or partially, located in the receiving device in the mounting position. "Mounting position" specifically refers to a position where the housing of the operating unit, preferably the operating unit, can be coupled to the receiving device, or is coupled to or locked in the receiving device by a mechanism. If pressure is applied to the operating element, it is preferable to first push the housing or operating unit further into the receiving device, especially axially. At this time, the housing preferably moves away from the receiving opening toward the abutment surface of the receiving device. For example, the abutment surface may form the bottom or base of the receiving device.

[0015] In another step, a rotational motion, particularly a counter-clockwise rotational motion, is applied to the rotating ring, thereby rotating the operating unit and removing the housing from its mounting position. Preferably, by rotating the locked rotating ring, the housing and the operating element rotate together, particularly automatically. In other words, if the rotating ring is locked by pressure applied to the operating element, rotating the rotating ring can cause the entire operating unit, i.e., particularly the housing, the operating element, and the rotating ring, to rotate together.

[0016] Preferably, the application of pressure to the operating element and the rotational movement are performed simultaneously or sequentially. In particular, pressure on the operating element is maintained during the rotational movement. When applying rotation and / or pressure, the housing is moved relative to the inner circumferential surface of the receiving device. Particularly preferably, a predetermined pressure is applied to the operating element, and thus simultaneously the locked rotating ring rotates, particularly counterclockwise. In particular, rotation occurs about the rotation axis of the operating device. In particular, the receiving device is not moved or rotated.

[0017] In another step, the pressing force is released, and the housing is moved toward the receiving opening of the receiving device, particularly by autonomous movement, to disassemble the operating unit. Specifically, the housing or operating unit can be moved vertically upwards, i.e., along the longitudinal axis of the operating device in the opposite direction to the force of the pressing force, from the receiving device. In particular, after the pressing force is released, especially after releasing the operating element and / or the rotating ring, the housing can be moved toward the receiving opening. Preferably, the housing or operating unit is moved axially upwards from the receiving device or pulled out.

[0018] For example, the operating unit or rotating ring is designed such that, during disassembly, the rotating ring can be locked by pressing down on the operating element, thereby allowing the operating unit to be unlocked from the receiving device, especially from the mounting position, without tools, particularly when rotating on the rotating ring. Specifically, the rotating ring can only be locked when the operating element is pressed. The operating unit can then be unscrewed, particularly from the mounting position, by the rotating ring. Particularly preferably, the operating unit can be unlocked, particularly from the receiving device, by applying pressure to the operating element while simultaneously rotating the rotating ring, particularly the locked rotating ring. In particular, the rotating ring can be rotated without applying pressure to the operating area or the operating element. This ensures that the user of the operating device or operating unit cannot "accidentally" unlock the operating element.

[0019] The resulting advantages are that the operating unit can be removed from the receiving device in a particularly simple and reliable manner. Furthermore, this method prevents damage to the operating unit. Additionally, the disassembly process is extremely quick. Moreover, no special tools are required for disassembly. This results in cost savings.

[0020] The present invention also includes embodiments that provide additional advantages.

[0021] One embodiment specifies that the rotating ring has a first profile on its inner surface. In other words, the rotating ring has a first profile on its inner circumferential surface. The inner circumferential surface is particularly arranged opposite to or facing the operating element of the rotating ring. Preferably, the first profile extends entirely along the circumferential direction of the inner circumferential surface. Furthermore, the operating element has a second profile on its lower side facing the housing and / or on its outer circumferential surface. In particular, the second profile extends along the outer radius of the operating element on its lower side and / or along the circumferential direction of the outer circumferential surface of the operating element. When a pressing force is applied to the operating element, the second profile engages with the first profile, preventing the rotating ring from rotating relative to the operating element. Preferably, when a predetermined pressing force is applied to the operating element, the second profile of the operating element engages with the first profile of the rotating ring. In particular, the predetermined pressing force is applied to the operating element perpendicular to the receiving opening. The rotating ring is prevented from rotating relative to the operating element by moving or rotating the operating element, particularly along the longitudinal axis of the operating device, through the pressing force, thereby engaging the second profile of the operating element with the first profile of the rotating ring. Therefore, the rotating ring and the operating element are preferably interconnected or linked in a form-locking and / or force-locking manner and / or in a manner that prevents relative rotation.

[0022] Another aspect of the invention relates to a method for inserting or installing an operating unit of an operating device into a receiving device of the operating device, wherein the operating unit includes a housing, an operating element, and a rotating ring, wherein the rotating ring surrounds the operating element, wherein the operating element and the rotating ring are arranged at a first end of the housing, and wherein the housing is connected to the rotating ring. In one step, the housing of the operating unit is arranged at a receiving opening of the receiving device. In particular, the housing is positioned in the receiving opening such that the operating unit or the housing can be inserted into the receiving device. In particular, a second end of the housing opposite to the first end is positioned at or within the receiving opening of the receiving device. In particular, the operating unit or the housing is inserted, particularly from above, into the receiving device through the receiving opening.

[0023] In another step, a pressing force is applied or loaded onto the operating element of the operating device, wherein the pressing force causes the housing to move through the receiving opening toward the contact surface of the receiving device opposite the receiving opening. If a pressing force is applied to the operating element, the housing or operating unit is preferably pushed, particularly axially, into the receiving device. At this time, the housing preferably moves away from the receiving opening toward the contact surface of the receiving device. For example, the contact surface may form the bottom or base of the receiving device.

[0024] Furthermore, the housing is at least partially received within a receiving device. In particular, the housing is arranged at least partially, i.e., completely or partially, within the receiving device by pressing the operating unit into it.

[0025] In another step, a rotational movement, particularly a clockwise rotation, is performed on the operating unit, thereby moving the housing within the receiving device toward its installation position. Specifically, the operating unit can perform the rotational movement automatically or autonomously. Preferably, the application of pressure and rotation are performed simultaneously or sequentially. During the rotational movement, the operating element and housing rotate accordingly, particularly due to the shape-locking of the rotating ring with the operating element and the connection between the rotating ring and the housing. When the rotational movement and / or the application of pressure are performed, the housing moves relative to the inner circumferential surface of the receiving device. Specifically, the receiving device is not moved or rotated. Specifically, the rotational movement occurs about the rotational axis or longitudinal axis of the operating device.

[0026] In another step, the pressing force is released, and the housing or operating unit is moved, particularly autonomously, into the mounting position within the receiving device. Preferably, after the pressing force is released, particularly after releasing the operating unit or operating element and / or rotating ring, the housing, particularly the operating unit, can slide or move into the mounting position. Subsequently, the operating unit, particularly the housing, can be locked in the mounting position. In the mounting position, particularly the operating unit, preferably the housing of the operating unit, can be coupled to the receiving device, or connected to or locked in the receiving device via a mechanism. Particularly preferably, insertion is performed downwards by applying a predetermined pressure to the operating unit until the operating unit rotates itself into the correct position and locks.

[0027] The resulting advantages are that the operating unit can be installed into the receiving device in a particularly simple and reliable manner. Furthermore, this method prevents damage to the operating unit. Additionally, the installation process is extremely quick. Moreover, no special tools are required for installation. This results in cost savings.

[0028] Additionally or alternatively, it may be specified that during installation, pressure is applied to prevent the rotating ring from rotating relative to the operating element. When the operating element is pressed, the rotating ring can no longer rotate about it. This is achieved, in particular, by moving or rotating the operating element, especially along the longitudinal axis of the operating device, through pressure, thereby engaging the second profile of the operating element with the first profile of the rotating ring. Thus, the rotating ring and the operating element are preferably form-locked and / or force-locked and / or connected to each other in a manner that prevents relative rotation.

[0029] If the operating unit or housing does not, in particular, automatically rotate into the installation position during installation, it may be additionally or alternatively specified that, during installation, a rotation, in particular a clockwise rotation, is applied to or performed on the locked rotating ring of the operating device, thereby rotating the housing and guiding it into the installation position.

[0030] The disassembly and / or installation of the operating unit and / or the application of pressure and / or the execution of rotational movements can be performed by the user and / or by the robot's robotic arm.

[0031] Another aspect of the invention relates to an operating device for a motor vehicle. The operating device includes an operating unit, wherein the operating unit includes an operating element, a rotating ring, and a housing. The operating device or operating unit may be designed, for example, as a volume controller. The operating element may be designed as a button or push button. Alternatively, the operating element may be designed as a capacitive operating element. The capacitive operating element may have an operating surface including a sensor film. The operating element may have a cylindrical shape.

[0032] Here, the rotating ring surrounds the operating element. In other words, the rotating ring encloses or frames the operating element. Specifically, the rotating ring is designed as an annular element surrounding the operating element. Specifically, the rotating ring is designed as an annular element surrounding the operating element. Specifically, the rotating ring is arranged on the outer peripheral surface of the operating element. The rotating ring can be coupled to and / or connected to the operating element.

[0033] Functions can be triggered by manipulating the operating element, such as applying a predetermined pressing pressure to the operating element or touching the operating surface of the operating element. Similarly, functions can be triggered by manipulating the rotating ring, such as applying rotation to the rotating ring, especially clockwise and / or counterclockwise rotation. For example, if the operating unit or operating device is designed as a volume controller, the volume can be adjusted by rotating the rotating ring. In particular, the rotating ring can be moved relative to the operating element. In other words, the rotating ring can perform relative movement with respect to the operating element.

[0034] The housing can have a cylindrical shape. In other words, the housing can have a cylindrical shape, especially a hollow cylindrical shape. An operating element and a rotating ring are arranged at a first end of the housing, wherein the housing is connected to the rotating ring. Additionally, the operating element can be connected to the housing. For example, support members for the rotating ring and / or the operating element can be arranged in the housing. In particular, the rotating ring can be connected to an operating shaft rotatably arranged in the housing.

[0035] At least two locking lugs are arranged on the surface of the housing, spaced apart from each other by a predetermined distance, particularly by a uniform distance. In other words, at least two locking lugs are arranged spaced apart from each other on the outer peripheral surface or outer periphery of the housing. In particular, the surface extends between a first end side and a second end side of the housing. In particular, "end side" refers to the end face, base surface, or top surface of the housing, especially a cylindrical housing. In particular, the corresponding end side extends perpendicular to the longitudinal axis or rotation axis of the housing or operating device. In particular, the rotation axis extends perpendicular to the operating surface and / or extends centrally or centrally through the operating device or operating surface. The operating device, especially the rotating ring and / or operating element and / or housing, is preferably rotatable about the rotation axis.

[0036] Preferably, 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 surface. These three locking lugs can be arranged at an angular distance of 120° from each other. In particular, "locking lug" refers to a protrusion, projection element, or ridge on the surface. In particular, at least two locking lugs are fastened or fixed to the surface. Furthermore, at least two locking lugs are preferably arranged on the same circular line on the surface or outer peripheral surface, or on the same plane or height on the surface or outer peripheral surface, or centrally located between the first end side and the second end side, or arranged at a predetermined distance from the respective end side.

[0037] Furthermore, the operating device includes a receiving device configured to at least partially receive the housing. In other words, the receiving device may at least partially, i.e., especially completely or partially, surround the housing. Preferably, a portion or region of the housing—especially at or through the first end side—extends from the receiving device. Preferably, the housing is arranged in the receiving device through a second end side opposite to the first end side, especially in the direction of the longitudinal axis of the operating device.

[0038] The receiving device has at least two guide grooves on its inner circumferential surface, wherein the guide grooves are configured to receive locking lugs respectively. In particular, the receiving device has at least two guide grooves on its inner side or on the surface facing the housing. Specifically, "guide groove" refers to a groove or recess extending on the inner side of the receiving device. Specifically, the guide grooves are respectively assigned to the locking lugs. The guide grooves extend axially—particularly along the longitudinal axis of the operating device—from the receiving opening of the receiving device toward the contact surface opposite the receiving opening, and transition into an arc-shaped or semi-circular section. Specifically, "contact surface" refers to the bottom of the receiving device.

[0039] In the installation position of the housing within the receiving device, the housing is at least partially received within the receiving device, and locking lugs are respectively arranged in locking positions within the guide grooves. Specifically, "installation position" means that the housing can be coupled to the receiving device, or connected to the receiving device via a mechanism including, in particular, the guide grooves and locking lugs. The locking positions are particularly located at the ends of the arcuate or semi-circular sections of the guide grooves. Particularly preferably, the locking lugs, together with the guide grooves, operate in the form of a locking mechanism, preferably in a snap-locking manner.

[0040] The resulting advantages are that the operating device has a particularly simple and stable structure. Furthermore, it reduces damage and shortens operation time when installing and / or removing the operating unit from the receiving device. Additionally, no special tools are required for installation and / or removal.

[0041] One embodiment specifies that the operating device or operating unit includes at least two spring elements, particularly three spring elements, wherein the spring elements are arranged on a second end side of the housing opposite to the first end side, particularly in the direction of the longitudinal axis of the operating device, and wherein the spring elements are configured to retain the locking lugs in their engaged position. Specifically, in the mounted position of the housing within the receiving device, at least two spring elements generate a reaction force, thereby pressing the locking lugs into their engaged position. The spring elements are particularly arranged between the second end face of the housing and the abutting surface of the receiving device. The resulting advantage is that the housing or operating unit is held in the receiving device in a particularly simple and reliable manner.

[0042] Preferably, at least two spring elements are arranged at the second end side at a predetermined distance from each other, especially a uniform distance—particularly along the outer periphery of the housing. For example, at least two spring elements are arranged at an angular distance of 180° from each other at the second end side. If the operating device includes, for example, three spring elements, these spring elements can be arranged at an angular distance of 120° from each other.

[0043] According to an advantageous improvement, at least two spring elements are designed as arms formed of an elastic material, wherein the arms are oriented toward the second end face at a predetermined angle, particularly at 45°. In other words, the arms are arranged to be inclined or oriented relative to the second end face at a predetermined angle, particularly at 45°. In particular, "arm" refers to a rod, mechanical component, or mechanical element. Preferably, the arms are formed of plastic, particularly of an elastic plastic.

[0044] Particularly preferably, the receiving device has a contact surface facing the second end side of the housing, wherein, in the installed position, at least two spring elements press against this contact surface. Specifically, in the installed position of the housing within the receiving device, one end of each of the at least two spring elements is arranged on the contact surface, while the other end is arranged on the second end side of the housing. The at least two spring elements are particularly arranged between the second end side of the housing and the contact surface of the receiving device. Preferably, in the installed position of the housing or operating unit, the spring elements push the operating unit or housing axially upwards along the vertical direction of the operating device or along the longitudinal axis or rotation axis of the operating device. In particular, the housing or operating unit is anchored in the snap-fit ​​position by locking lugs to prevent it from sliding out of the receiving device. In the installed position, at least two spring elements are particularly clamped. Preferably, in the installed position of the housing within the receiving device, the angle of inclination of the spring elements relative to the second end side is less than 45°. The resulting advantage is that the housing is held in the receiving device in a particularly simple and reliable manner.

[0045] Advantageously, the rotating ring has a first profile on its inner surface. In other words, the rotating ring has a first profile on its inner circumferential surface. The inner circumferential surface is particularly arranged opposite to or facing the operating element from the outer circumferential surface of the rotating ring. Preferably, the first profile extends entirely along the circumferential direction of the inner circumferential surface. For example, the first profile can be designed as a toothed profile, a sawtooth profile, or a wave-shaped profile. Furthermore, the operating element has a second profile on its lower side facing the housing and / or on its outer circumferential surface. In particular, the second profile extends along the outer radius of the operating element on its lower side and / or along the circumferential direction of the outer circumferential surface of the operating element. For example, the second profile can be designed as a toothed profile, a sawtooth profile, or a wave-shaped profile. Furthermore, the second profile can engage with the first profile, particularly preventing the rotating ring from rotating relative to the operating element. Preferably, the first and second profiles are designed to be identical or coincident with each other. For example, if the first and second profiles are designed as toothed profiles, the teeth of the second toothed profile of the operating element can engage or be pushed between the teeth of the first toothed profile of the rotating ring. In particular, the first tooth profile and the second tooth profile can mesh or engage with each other. Preferably, when a predetermined pressing force is applied to the operating element, the second profile of the operating element engages with the first profile of the rotating ring.

[0046] Another embodiment specifies that the rotating ring has a tab on its inner surface, the tab extending circumferentially along the inner surface. In other words, the rotating ring has a tab on its inner circumferential surface, which is particularly arranged opposite to or facing the operating element from the outer circumferential surface of the rotating ring, and the tab extends entirely along the circumferential direction of the inner circumferential surface. In particular, the tab is arranged between a first end of the housing and the operating element. The tab has a first profile on its upper side facing the operating element. The upper side of the tab preferably extends perpendicular to the inner surface of the rotating ring.

[0047] Specific embodiments of a method for installing an operating unit of an operating device into a receiving device of an operating device, and specific embodiments of a method for removing an operating unit of an operating device from a receiving device of an operating device, will be described in more detail below.

[0048] In a method for installing an operating unit of an operating device into a receiving device of the operating device, in one step, a housing may be arranged at a receiving opening of the receiving device, and at least two locking lugs may be arranged in guide grooves of the receiving device. Specifically, the housing is positioned in the receiving opening such that the locking lugs can be inserted into the guide grooves respectively. In particular, the housing is inserted into the receiving device through the receiving opening—especially from above—and the locking lugs are positioned in the guide grooves.

[0049] Subsequently, a pressing force is applied to the operating element of the operating device. In particular, a predetermined pressing force is applied to the operating element perpendicular to the receiving opening. This pressing force prevents the rotating ring from rotating relative to the operating element. The rotating ring cannot rotate about the operating element while it is being pressed. This is achieved, in particular, by moving or rotating the operating element, especially along the longitudinal axis of the operating device, through the pressing force, thereby engaging the second contour of the operating element with the first contour of the rotating ring. Thus, the rotating ring and the operating element are preferably interconnected or connected in a form-locking manner.

[0050] By applying pressure, the locking lug can be moved within the guide groove toward the contact surface opposite the receiving opening. In particular, the locking lug can be moved axially upward within the guide groove. In other words, the locking lug can be pressed into the receiving device in a guided manner within the guide groove, especially toward the contact surface.

[0051] In another step, a rotational movement, particularly a clockwise rotational movement, can be applied to the rotating ring of the operating device, thereby rotating the housing and guiding the locking lug to the engaged position. Preferably, the application of pressure and the rotational movement are performed simultaneously or sequentially. When the rotational movement is applied to the rotating ring, the operating element and the housing rotate accordingly, particularly through the form-locking of the rotating ring and the operating element and the connection between the rotating ring and the housing. When the rotational movement and / or the pressing force are applied, the housing is moved relative to the inner circumferential surface of the receiving device. In particular, the receiving device is not moved or rotated. In particular, the rotational movement is about the rotation axis of the operating device.

[0052] When applying pressure, it is preferable to move the locking lug within the axial section of the guide groove. When applying rotational motion, in particular, the locking lug is moved from this axial section of the guide groove into a semi-circular or arc-shaped section of the guide groove.

[0053] In another step, the pressing force can be released, and the locking lug—particularly autonomously or automatically—can move within the guide groove to the engaged position. Specifically, after the pressing force is released, particularly after releasing the operating element and / or the rotating ring, the locking lug can slide into the engaged position. This movement of the locking lug to the engaged position is caused, in particular, by a spring element—particularly towards the receiving opening—applying a pressing or reaction force to the housing. When a pressing force is applied to the operating element, the spring element can be tensioned and a reaction force applied. This reaction force presses the locking lug into its engaged position within the guide groove.

[0054] In a method for disassembling the operating unit of an operating device from the receiving device of the operating device, in one step, a pressing force can be applied to the operating element, wherein the pressing force acting on the operating element prevents the rotating ring from rotating relative to the operating element. Specifically, the rotating ring is prevented from rotating relative to the operating element by pressing the operating element, particularly by moving or rotating it along the longitudinal axis of the operating device, thereby engaging the second contour of the operating element with the first contour of the rotating ring. Thus, the rotating ring and the operating element are preferably interlocked or connected in a form-locking manner.

[0055] In another step, a rotational motion, particularly a counterclockwise rotational motion, is applied to the rotating ring. Preferably, the housing and operating element rotate accordingly with the rotation of the rotating ring, particularly automatically. Preferably, the application of pressure to the operating element and the rotational motion are performed simultaneously or sequentially. When applying the rotational motion and / or the pressure, the housing or operating element is moved relative to the inner circumferential surface of the receiving device. In particular, the receiving device is not moved or rotated. In particular, the rotational motion is performed about the rotation axis of the operating device.

[0056] By applying pressure, the locking lug can be guided or moved within the guide groove from its engaged position—especially axially—towards the contact surface opposite the receiving opening. By rotational movement, the locking lug can be moved or guided out of its engaged position within the guide groove about the rotation axis of the operating device. In other words, when a rotational movement is applied to the rotating ring, the housing or operating unit is rotated such that the locking lug is moved out of its engaged position within the guide groove. When applying pressure or rotational movement, the locking lug is preferably moved or guided within the semi-circular or arcuate section of the guide groove to its axial section.

[0057] During disassembly, pressure is applied to the operating element while rotating, preferably counterclockwise, the rotating ring that is thus locked. Therefore, the locking lugs can be simultaneously pushed downwards, i.e., along the longitudinal axis, from their engaged position—especially counterclockwise—in the direction of the pressing force.

[0058] In another step, in particular, the pressing force is released, and the locking lug is moved, particularly autonomously, from the receiving device towards the receiving opening within the guide groove—especially axially toward the receiving opening. Specifically, the locking lug can be drawn vertically upwards, i.e., along the longitudinal axis in the opposite direction to the force of the pressing force, from the receiving device. Especially after the pressing force is released, particularly after releasing the operating element and / or the rotating ring, the locking lug can be moved toward the receiving opening.

[0059] The predetermined pressing force or pressing force value applied to the operating element during installation and / or disassembly is preferably greater than the pressing force or pressing force value applied to the operating element when manipulating the operating element.

[0060] When installing the operating unit of the operating device into the receiving device of the operating device, in particular, the housing is arranged together with the operating element and rotating ring disposed on the first end side of the housing in the receiving device. When removing the housing or operating unit of the operating device from the receiving device of the operating device, in particular, the housing is removed together with the operating element and rotating ring disposed on the first end side of the housing from the receiving device.

[0061] Another aspect of the invention relates to a cover or shield for a motor vehicle having an operating device according to the invention.

Attached Figure Description

[0068] Embodiments of the present invention are described below. For this purpose, only the accompanying drawings (…) Figure 1 The diagram shows the operating device 12 arranged on the cover plate 10. Detailed Implementation

[0069] The embodiments described below are preferred embodiments of the present invention. In the embodiments, the components described in the embodiments are individual features of the present invention that can be considered independent of each other, and these features also independently improve the present invention. Therefore, this disclosure should also include feature combinations different from the feature combinations of the illustrated embodiments. Furthermore, the described embodiments can also be supplemented by other features among the features already described in the present invention.

[0070] In the accompanying drawings, the same reference numerals denote elements that have the same function.

[0071] Figure 1An operating device 12 is shown, arranged or installed on a visor 10 for a motor vehicle. For example, the operating device 12 is designed as a volume controller. The operating device 12 includes an operating unit 13. The operating unit 13 has an operating element 14. The operating element 14 has a cylindrical shape. The operating element 14 is designed, for example, as a button or key. The operating element 14 has an operating surface 16, particularly a sensitive operating surface 16. For example, the operating surface 16 has, in particular, a capacitive sensor membrane. The operating surface 16 is divided into different operable areas, which are identified by different symbols. Functions, such as device functions, can be controlled by the user performing an operating action at the corresponding area, such as pressing or touching the corresponding area. The operating element 14 can move or be moved along the longitudinal axis or main axis of the operating device 12. In other words, the operating element 14 can move axially. When pressure is applied to the operating element 14, the operating element 14 can be moved or be moved along the longitudinal axis of the operating device 12. If the operating element 14 is released after the pressure is applied, the operating element can return to its original position in the opposite direction of the pressure.

[0072] Furthermore, the operating unit 13 includes a rotating ring 18. The rotating ring 18 surrounds or frames the operating element 14. In other words, the independent rotating ring 18 can surround the operating element 14. The rotating ring 18 is arranged along the outer peripheral surface of the operating element 14. The rotating ring 18 has an annular shape or a hollow cylindrical shape. Here, the inner surface of the rotating ring 18 faces the operating element 14. In particular, the rotating ring 18 can move relative to the operating element 14. At this time, the rotating ring 18 can be rotated, especially about the rotation axis or longitudinal axis of the operating device 12. In particular, the rotating ring 18 can be rotated about the operating element 14 without applying pressure to the operating element 14. For example, if the operating device 12 or the operating unit 13 is designed as a volume controller, the rotating ring 18 can be used to adjust the volume. Rotating the rotating ring 18 clockwise can increase the volume. Rotating the rotating ring 18 counterclockwise can decrease the volume.

[0073] Furthermore, the operating unit 13 has a housing 20. The rotating ring 18 and / or the operating element 14 are coupled or connected to the housing 20. For example, a support member for the rotating ring 18 and / or the operating element 14 may be received in the housing 20. The rotating ring 18 and / or the operating element 14 are arranged on a first end side 22 of the housing 20. The housing 20 is particularly cylindrical in shape. Preferably, the housing 20 is hollow cylindrical in shape. The housing 20 includes the first end side 22, and particularly includes a second end side 24 opposite to the first end side 22 in the main extending direction or longitudinal axis direction of the operating device 12. A surface 26 of the housing 20 extends between the first end side 22 and the second end side 24.

[0074] As from Figure 1As can be seen, locking lugs 28 are arranged on surface 26 of housing 20. In other words, locking lugs 28 are arranged on the outer peripheral surface of housing 20. Operating device 12 has at least two locking lugs 28, preferably three or four. Preferably, the locking lugs 28 are centrally arranged on surface 26 between the first end side 22 and the second end side 24. At least two locking lugs 28 are arranged at a predetermined distance from each other. For example, the two locking lugs 28 may be arranged on the outer peripheral surface or surface 26 at an angular distance of 180° from each other. For example, if operating device 12 has three locking lugs 28, these three locking lugs may be arranged at an angular distance of 120° from each other. The locking lugs 28 are arranged on the outer peripheral surface or surface 26 at the same height, at the same radius, or along the same circular line.

[0075] Furthermore, the operating device 12 includes a receiving device 30. The receiving device 30 is configured to at least partially, i.e., completely or partially, receive the housing 20 of the operating unit 13. The housing 20—especially in the installation position—is at least partially received or arranged within the internal space or receiving area of ​​the receiving device 30. The shape of the internal space or receiving area of ​​the receiving device 30 is adapted to the shape of the housing 20. Figure 1 In this configuration, the housing 20 or operating unit 13 is positioned within the receiving device 30. The housing 20 can be inserted into the receiving device 30 through the receiving opening 31. The receiving device 30 has a guide groove 32 on the surface 26 facing the housing 20. In particular, the housing 20 has the guide groove 32 on its inner circumferential surface or inner surface. Figure 1 Only one guide groove 32 is shown. The receiving device 30 includes at least two guide grooves 32. The two guide grooves 32 are designed to be identical or the same. Preferably, the receiving device 30 has three guide grooves 32. In particular, the number of guide grooves 32 corresponds to the number of locking lugs 28. The guide grooves 32 are configured to receive the locking lugs 28. The guide grooves 32 are arranged on the inner circumferential surface of the receiving device 30 at a predetermined distance from each other—especially a uniform distance. For example, two guide grooves 32 may be arranged on this surface or inner circumferential surface at an angular distance of 180° from each other. For example, if the operating device 12 has three guide grooves 32, these three guide grooves may be arranged at an angular distance of 120° from each other.

[0076] As from Figure 1 As can be seen, the guide groove 32 has a J-shaped shape. The guide groove 32 extends axially first along the main extension direction, longitudinal axis, or rotation axis of the operating device 12. In other words, the guide groove 32 has an axial section. The guide groove 32, especially the axial section, extends from the receiving opening 31 of the receiving device 30. The axial section transitions into a U-shaped section, a semi-circular section, or an arc-shaped section. Figure 1 In the guide groove 32, the locking lug 28 is located in the locking position 33. The locking position 33 is located at the end or end region of the guide groove 32. The locking position 33 is arranged at the end of the arc-shaped section of the guide groove 32.

[0077] Furthermore, the operating device 12 or operating unit 13 includes at least two, preferably three or four spring elements 34. The spring elements 34 are arranged or fixed to the second end side 24 of the housing 20. The spring elements 34 are arranged on the second end side 24 of the housing 20 at a predetermined distance from each other. The spring elements 34 are arranged along the outer periphery or outer radius of the second end side 24. For example, two spring elements 34 may be arranged on the second end side 24 at an angular distance of 180° from each other. For example, if the operating device 12 has three spring elements 34, these three spring elements 34 may be arranged at an angular distance of 120° from each other. Preferably, the spring elements 34 are made of an elastic material, such as 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 relative to the second end side 24 of the housing 20. For example, the spring elements 34 are arranged at an angle of 45° relative to the second end side 24 of the housing 20 or oriented at a 45° angle relative to the second end side 24. In particular, when the spring element 34 is not tensioned, the angle is 45°. Figure 1 In the installed position, the housing 20 is located within the receiving device 30. In the installed position, the locking lug 28 is in the engaged position 33 and the spring element 34 is tensioned. In the installed position, a pressing force is applied to the spring element 34 in the direction of the rotation axis, longitudinal axis, or main extension direction of the operating device 12, particularly from the first end side 22 towards the second end side 24. To hold the locking lug 28 in the engaged position, the spring element 34 applies a reaction force. This reaction force acts in the direction of the rotation axis, longitudinal axis, or main extension direction of the operating device 12, particularly from the second end side 24 towards the first end side 24.

[0078] Furthermore, the operating device 12 or operating unit 13 includes a connector 38. The connector 38 allows for the supply of electrical power to the operating device 12 or operating unit 13, or for connection to the vehicle's onboard electrical system. The connector 38 is located on the lower side 40 of the receiving device 30. This lower side 40 is opposite to the receiving opening 31 through which the housing 20 can be inserted into the receiving device 30.

[0079] exist Figure 1In the mounting position, the housing 20 or operating unit 13 is located within the receiving device 30. The receiving device 30 has a contact surface 36 facing the second end side 24 of the housing 20. In the mounting position, a spring element 34 presses against the contact surface 36. In the mounting position, the spring element 34 is arranged on the contact surface 36. In particular, in the mounting position, the spring element 34 is tensioned between the second end side 24 and the contact surface 36.

[0080] exist Figure 1 In the mounting position, the housing 20, together with the operating element 14 and the rotating ring 18 arranged on the housing, is located in the receiving device 30. The receiving device 30 is arranged or fixed to the rear side 42 of the cover 10. The operating element 14 and the rotating ring 18 are arranged on the front side 44 of the cover 10 opposite to the rear side 42. The cover 10 can be a cover 10 for a motor vehicle. The cover 10 or cover can be installed in the interior space of a motor vehicle, especially at the center console of a motor vehicle. Thus, the front side 44 of the cover 10 forms the visible side of the cover 10.

[0081] The baffle 10 has a baffle opening 46. The baffle opening 46 is designed to be circular. The receiving device 30 is arranged on the rear side 42 of the baffle 10 such that the baffle opening 46 and the receiving opening 31 of the receiving device 30 are aligned with each other. In particular, the extension range of the receiving opening 31 is the same as the extension range of the baffle opening 46. The receiving opening 31 is also designed to be circular. In particular, the diameter of the receiving opening 31 and the baffle opening 46 is the same.

[0082] The insertion and removal of the operating unit 13 into and from the receiving device 30 will be described more precisely below. To install the operating unit 13, particularly the housing 20 along with the operating element 14 and the rotating ring 18 arranged on the housing, the housing 20 of the operating unit 13 is positioned at the receiving opening 31. Furthermore, a locking lug 28 is arranged on the guide groove 32. Here, the locking lug 28 is positioned at the opening or insertion area of ​​the guide groove 32. Thus, the housing 20 is positioned such that the locking lug 28 can be pushed into or inserted into the guide groove 32. In particular, the housing 20 is guided through the cover opening 46 perpendicular to the front side 44 of the cover 10, and / or the cover is positioned at the receiving opening 31 of the receiving device 30. To allow the locking lug 28 to slide into the guide groove 32, a predetermined pressure or predetermined pressing force is applied to the operating element 14, particularly perpendicular to the front side 44 of the cover 10 or perpendicular to the operating surface 16. Simultaneously, the rotating ring 18 is rotated clockwise. Once a pressing force is applied to the operating element 14, the rotating ring 18 is locked, thus preventing the rotating ring 18 from rotating or moving relative to the operating element 14. That is, if the rotating ring 18 is rotated under the action of the pressing force, the operating element 14, the rotating ring 18, and the housing 20 rotate together about the rotation axis or longitudinal axis of the operating device 12. By this pressing force, the locking lug 28 and / or the housing 20 are guided axially upward from the receiving opening 31 toward the contact surface 36 or toward the lower side 40 of the receiving device 30. By this rotational movement, the locking lug 28 is transferred 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 element 34 presses the locking lug 28 into the locking position 33.

[0083] To remove the housing 20 from the receiving device 30, pressure is applied again to the operating element 14, and the rotating ring 18 is rotated counterclockwise. Pressure is applied perpendicular to the front side 44 of the cover 10 and / or perpendicular to the operating surface 16. This pressure locks the rotating ring 18 again, so that the rotating ring 18 can no longer rotate or move relative to the operating element 14. That is, if rotational movement is applied to the rotating ring 18 under the action of pressure, the operating element 14, the rotating ring 18, and the housing 20 rotate together about the rotation axis or longitudinal axis of the operating device 12. Therefore, the locking lug 28 is pressed downward and simultaneously pushed out of its engaged position 33, and can be moved axially upward again from the guide groove 32.

[0084] To lock the rotating ring 18, the rotating ring 18 has a tab on its inner surface facing the operating element 14. The tab extends circumferentially along the inner surface of the rotating ring 18. In other words, the tab is arranged on the inner circumferential surface of the rotating ring. On the upper side of the tab facing the operating element 14 or arranged opposite the operating surface 16, the tab has a first profile, such as a toothed profile or a serrated profile. The operating element 14 has a second profile, such as a toothed profile or a serrated profile, on its lower side facing the housing 20, wherein the second profile can engage with the first profile.

[0085] In general, the examples demonstrate how operating equipment can be installed and / or disassembled from above without the need for tools.

[0086] This assembly method allows the volume controller to be installed into and / or removed from the center console without disassembling or installing the center console cover. No special tools are required for installation and / or removal. After contacting the connector, installation can be performed by pressing down on the volume controller, operating unit, or operating element until the volume controller or operating unit rotates itself into the correct position and locks or latches therein. For removal, the operating area or surface of the volume controller or the operating element or operating unit can be pressed down while simultaneously rotating the volume rotating ring or rotating ring that is locked therein counterclockwise until the locking lug disengages from the support or snap-in position again, allowing the volume controller or operating unit to be removed upwards. The volume controller or operating unit will not accidentally come loose because it will return to its latched position if the rotating ring is not rotated simultaneously.

[0087] Specifically, the volume controller or operating unit includes three locking lugs that secure the volume controller or operating unit in the guide slots of the retainer or receiving device. After contacting the connector, if the volume controller is inserted into the support or receiving device from above and the three locking lugs are in place, it is only necessary to press the operating surface from above. The three locking lugs can slide into the guide slots, and the volume controller can automatically rotate into place, so that upon release, the volume controller slides up into the locking or engaged position.

[0088] Disassembly can only be performed by applying pressure to the operating area while simultaneously rotating the locked rotating ring or volume ring counterclockwise. The operating unit can be unlocked again without tools by pressing and simultaneously rotating the rotating ring. If the operating element is not pressed, the rotating ring can rotate, preventing the operating unit from being "accidentally" unlocked. The rotating ring is locked only when the operating area is pressed. The operating unit can then be unscrewed using the rotating ring. Therefore, the locking lug can be pressed simultaneously from its fixed position, or snap-in position, to the right or counterclockwise downwards, and can be removed vertically upwards from the support or receiving device.

[0089] Three to four return springs can generate a reaction force.
