Description

State of the art

[0001] From DE 10 2018 103 350 A1 a control element for a vehicle interior is known. Disclosure of the invention

[0002] A proposed input device for entering a command comprises one or more control elements with a first surface facing the user and a second surface opposite the first surface, facing away from the user. The input device further comprises one or more piezoelectric motors with a threaded rod for moving one or more of the control elements between a starting position and an end position, the threaded rod being located on or extending along the second surface of the control element and along a direction of movement of the control element.Furthermore, the input device has a receiving element with a user-facing surface for receiving one or more control elements and one or more piezo motors, wherein the user-facing surface of the receiving element and the first surface of the one or more control elements are arranged on the same plane in the initial position, and wherein the first surface of the control element is extended or lowered relative to the receiving element in the end position.

[0003] The advantage lies in the fact that the proposed input device enables the operation of one or more functions, for example, in a vehicle. For instance, one or more displays in a vehicle can be controlled using the proposed input device. The input device becomes visible particularly when needed. Preferably, the input device or control element is then extended or retracted and can, in particular, receive a command if this is necessary and / or desired by a user. This prevents the user from being distracted by too many elements on a user interface. If the input device is located in a vehicle, the user could, for example, be a vehicle occupant, such as the driver. This allows the vehicle occupant to...The driver is not distracted by too many elements in the vehicle interior, thus increasing road safety. Furthermore, the removal of the control element when not in use can reduce injuries, for example, from bumping into or getting caught on the input device.

[0004] The advantage of piezoelectric motors, or piezomotors for short, lies in their small size, which utilizes the piezoelectric effect to generate linear or rotary motion. This advantageously reduces the required installation space, allowing for flexible integration of the input device in areas with limited space. In other words, the proposed input device saves installation space. Furthermore, it can advantageously reduce costs, optimize noise levels, and / or increase temperature resistance. Another benefit is improved durability and thus cycle stability.

[0005] Another advantage is that morphing out of and into the surface is possible. In other words, concave and convex shape changes of the surface can be achieved using piezoelectric motors. A further advantage is that piezoelectric motors can move to defined positions. This eliminates the need for additional components that would otherwise be required for precise positioning. Advantageously, a high-resolution piezoelectric motor cluster can be generated to create freeform surfaces. A piezoelectric motor cluster can be understood as a large number of piezoelectric motors arranged, for example, in rows and columns on a surface with minimal spacing and / or high resolution, to move the control elements or surface segments mounted on the motors independently up and down, thereby creating a kind of freeform surface.Advantageously, this allows for quiet, precise and / or reproducible shape changes of surfaces.

[0006] In an advantageous embodiment, the receiving element can have a recess or cavity in the shape of the control element, wherein the control element, in its initial position, partially or completely fills the recess. Alternatively or additionally, the receiving element can have one or more stops, wherein the control element can be lowered / extended to the stop in the end position and raised / lowered to a stop in the initial position. This allows the different positions to be approached easily and / or safely. Advantageously, the control element can disappear into the receiving element in its initial position, making it invisible to an observer or user. This can increase road safety.

[0007] In one exemplary implementation, the piezoelectric motor can be controlled at a high frequency to generate feedback. This allows the user to receive haptic feedback. Advantageously, the user can keep their eyes on the road and have their commands confirmed by haptic feedback, thus increasing road safety.

[0008] In an advantageous embodiment, the input device can have an elastic layer, wherein the elastic layer is arranged on the receiving element on a user-facing side of the input device such that at least part of the control element is covered with the elastic layer, that the elastic layer forms a flat surface in the starting position, and that the elastic layer is deformable when the control element is moved to or towards the end position. An advantage is that the area under the control element is protected, as the ingress of dust, dirt particles, and / or water or moisture into crevices and / or into the area where the actuator is located can be prevented or reduced. Advantageously, this makes the input device easier to clean.

[0009] In a further development, the elastic layer can be attached to the receiving element. For example, the elastic layer can be attached to the receiving element by means of a material-bonded connection. In an advantageous embodiment, the elastic layer can be attached to the receiving element by means of an adhesive bond. This attachment ensures that the elastic layer is formed as a flat surface in its initial position. Furthermore, it ensures that the elastic layer deforms in its final position in such a way that it adapts to the control element or its shape. This allows the user to clearly perceive the control element, particularly in its predetermined shape. This ensures the functionality of the input device. It also prevents the elastic layer from slipping.The elastic design of the layer allows, in particular, the restoration of a previously flat surface after deformation by the operating element.

[0010] Advantageously, the area of ​​the elastic layer located above the control element can be designed as a touch-sensitive layer. This allows a user to enter commands or make inputs via the touch-sensitive layer safely and / or reliably.

[0011] In a further development, the input device can have an elastic layer, wherein the elastic layer is arranged on the receiving element and on the second surface of the control element facing away from the user, and wherein the elastic layer is deformable when the control element is moved to or towards its end position. An advantage is that the area under the control element is protected, as the ingress of dust, dirt particles, and / or water or moisture into crevices and / or into the area where the actuator is located can be prevented or reduced.

[0012] Preferably, the first surface of the control element can be designed as a touch-sensitive surface. This allows a user to enter commands via the touch-sensitive surface in a particularly safe and / or reliable manner.

[0013] In one exemplary embodiment, a command can be determined by moving the control element and / or by pressing on it. Advantageously, the control element can be moved, particularly in a vertical direction, and / or pressure can be applied to it. This allows a command to be issued via the control element, and thus the input device, to be recognized reliably and / or securely. This enables the corresponding action to be carried out in response to the command.

[0014] In a further development, the input device can have a sensor for detecting a user's approach, whereby the control element moves to its end position when the sensor detects the user's approach. Furthermore, the input device can, in particular, have a sensor for detecting a user's departure from the input device, whereby the control element moves to its starting position when the sensor detects the user's departure. This allows the device to detect when a user intends to use it, with the control element then moving to its end position as soon as a user's approach is detected. Subsequently, after use and / or when a user moves away from the input device, the control element can be moved back to its starting position.This allows the control element to be available when needed, thus preventing user distraction when the user does not require it. If the input device is located in a vehicle, the reduced distraction of the user, especially a vehicle occupant or driver, increases road safety.

[0015] Furthermore, a method for moving a control element of an input device according to one of the preceding claims is proposed, comprising the steps of controlling the piezo motor to move the control element, wherein the control element is moved from the starting position to the end position by means of the piezo motor, Controlling the piezo motor to move the control element, whereby the control element is moved from the end position to the starting position by means of the piezo motor.

[0016] In a further development, the method includes a step of detecting a user's approach using a sensor, whereby the control element is then moved to its end position when the sensor detects the user's approach, and a step of detecting a user's departure using the sensor, whereby the control element is then moved back to its starting position when the sensor detects the user's departure. This allows the control element to be available when needed, thereby increasing road safety in particular.

[0017] Furthermore, a method for entering a command by means of an input device is proposed, comprising the steps of controlling the piezo motor to move the control element, wherein the control element is moved from the starting position to the end position by means of the piezo motor, Capturing an input of a command by a movement of the control element performed by a user and / or by means of a touch-sensitive surface of the control element and / or by means of a touch-sensitive surface of the elastic layer.

Embodiments of the invention:

[0019] Fig. Figure 1 shows a schematic representation of an input device 20. The input device 20 is designed for inputting a command. The input device 20 can, for example, be arranged in a vehicle, for instance according to Fig. 5.

[0020] The input device 20 has one or more control elements 22, each with a first surface 24 facing the user and a second surface 25 opposite the first surface 24 and facing away from the user. In this advantageous embodiment, the input device 20 has only one control element 22. However, the input device 20 can also have two or more control elements 22. The control element 22 can, in particular, be round, oval, rectangular, or rectangular with rounded corners or with multiple corners, as viewed from the user's perspective.

[0021] The input device 20 has one or more piezoelectric motors 26 with a threaded rod 27 for moving one or more of the control elements 22 between a starting position and an end position. The threaded rod 27 is arranged on the second surface 25 of the control element 22 and extends along a direction of movement of the control element 22. In this advantageous embodiment, the input device 20 has only one piezoelectric motor 26. However, the input device 20 can also have, for example, two or more piezoelectric motors 26. Advantageously, the piezoelectric motor 26 moves the control element 22 back and forth between different positions, preferably the starting position and the end position. The movement can be performed in two stages, several stages, and / or continuously. In other words, the control element 22 can be moved from the starting position to the end position by means of the piezoelectric motor 26.The control element 22 can be moved and returned to its original position. It can be moved or traversed perpendicular to the operating surface. In this advantageous embodiment according to... Fig. Figure 1 shows the control element 22 in its initial position. The arrangement of the control element 22 in its final position can be described below. Fig. 3 and / or Fig. 4 trained.

[0022] The threaded rod 27 is arranged, in particular, along and / or parallel to the direction of movement of the control element, or extends along and / or parallel to the direction of movement of the control element. In an advantageous embodiment, the threaded rod 27 has an axis of symmetry. Preferably, the axis of symmetry of the threaded rod 27 is arranged parallel to a direction of movement of the control element 22. Preferably, the axis of symmetry of the threaded rod 27 is arranged approximately perpendicular to the first surface 24 of the control element 22.

[0023] The piezoelectric motor 26 converts a rotary movement via the threaded rod 27 into a vertical movement of the threaded rod along arrow 31. The attached control element 22 is moved accordingly by means of this vertical movement of the threaded rod 27. In other words, the piezoelectric motor 26 moves the threaded rod 27 vertically along arrow 31, specifically along the axis of symmetry of the threaded rod 27, thereby moving the control element 22. This allows the control element 22 to be extended or retracted. The positions, especially the end position and / or the starting position, of the control element 22 can be precisely controlled or assumed by means of the piezoelectric motor 26.

[0024] Preferably, small piezoelectric motors or miniature piezoelectric actuators can be used, which are quiet and require little installation space. Furthermore, these small piezoelectric motors must generate only minimal forces, advantageously just enough to deform a surface in vehicle interiors by a few millimeters, or, if no elastic layer is applied over the control element, just enough to lift the weight of the control element.

[0025] The input device 20 further comprises a receiving element 28 with a user-facing surface 29 for receiving one or more control elements 22 and one or more piezo motors 26, wherein the user-facing surface 29 of the receiving element 28 and the first surface 24 of the one or more control elements 22 are arranged on the same plane in the initial position, and wherein the first surface 24 of the control element 22 is extended in the end position relative to the receiving element 28, see Fig. 3, or lowered, see Fig. 4. In other words, the control element 22 is arranged in the receiving element 28 or within the receiving element 28 in its initial position. In particular, the control element 22 thus disappears within the receiving element 28. As a result, in the initial position, there is no protrusion or indentation by the control element 22 out of or into the receiving element 28. The receiving element 28 can, for example, be designed as a housing or support, wherein the housing or support in particular receives the control element 22 and the piezoelectric motor 26. In an exemplary embodiment, the receiving element 28 can be part of an instrument panel, a storage compartment and / or an armrest, in particular a center console, of a vehicle, or be arranged in or on an instrument panel, a storage compartment and / or an armrest, in particular in a center console, of a vehicle, see Fig. 5.

[0026] In this advantageous embodiment, the receiving element 28 has a recess 34 or a cavity 34 in the form of the operating element 22. Advantageously, the recess 34 is designed such that the operating element 22 can move into the recess 34 for the end position. Advantageously, the receiving element 28 can have a stop 36, wherein the operating element can be lowered to the stop 36 in the end position. In an alternative embodiment, the operating element 22, arranged in the initial position, can partially or completely fill the recess.

[0027] The input device 20 advantageously has a side 32 facing the user. In particular, the first surface 24 of the control element 22 is arranged in the direction of the first side 32. Preferably, a user or a user's hand is located on the first side 32 of the input device 20, especially for operating the input device 20.

[0028] Advantageously, a command can be determined or entered by moving the control element 22 and / or by pressing on the control element 22, in particular by means of a control unit and / or processing unit and / or computing module on the circuit board. In other words, pressure applied to the control element 22 can be interpreted and evaluated as a user command. Preferably, the control element 22 can be moved in a vertical direction for actuation. In particular, pressure can be applied to the control element 22 for actuation and / or for entering a command, preferably by a user or their finger or hand. Advantageously, this pressure can be measured. The sensor(s) for detecting the pressure applied by the user can be...For example, a classic push button, a pressure sensor, a piezoelectric sensor, an electroactive polymer, optical, resistive, or other suitable sensors can be used. In a further development, push buttons can be arranged or integrated.

[0029] Alternatively or additionally, the first surface 24 of the control element 22 can be designed as a touch-sensitive surface, for example by means of capacitive or resistive area sensors. Preferably, input can be made by touching the touch-sensitive surface.

[0030] A function for entering a command can be activated, in particular, when the control element 22 is in its end position. Preferably, a function for entering a command can be deactivated when the control element 22 is in its home position. In an alternative embodiment, the function can also be activated in the home position. In this case, a command can also be entered in the home position.

[0031] In a further development, the input device 20 can have a sensor 50 for detecting a user's approach to the input device 20. In other words, a user's approach can be detected by means of a sensor 50. In this advantageous embodiment, the sensor 50 is arranged in or on the control element 22. In a further development, the sensor 50 can also be arranged at a different position in the input device 20. The input device 20 can have one or more sensors 50, which are, for example, distributed, particularly around the control element 22. Alternatively or additionally, the sensor 50 can be arranged in or on the receiving element 28.In other words, one or more proximity sensors 50, in particular capacitive proximity sensors 50, can be arranged in the receiving element 28, for example around the control element 22, or in the control element 22 itself, to detect the approach of the user, for example a hand and / or one or more of the user's fingers, from different directions. Preferably, the one or more proximity sensors 50 can be configured as radar sensors, ultrasonic sensors, capacitive sensors, and / or optical sensors. When the sensor 50 detects the approach of the user, in particular a hand or one or more fingers, the control element 22 is moved to its end position, in particular by means of the piezoelectric motor. In other words, the input device 20 can be activated by the system or by the user themselves, for example by bringing their hand close.

[0032] The sensor 50 can further be configured to detect when a user moves away from the input device 20. In other words, the sensor 50 can also detect when the user moves away from the control element 22 and thus away from the input device 20. If the sensor 50 detects that the user has moved away, then the control element 22 can be moved back to its initial position.

[0033] Alternatively or additionally, the movement of the control element 22 to the end position can also be triggered by a function or the occurrence of a specific situation. For example, the control element 22 can be moved to the end position when a user is required to provide a specific input, when such input is necessary, and / or is expected. If the input device 20 is located in a vehicle, for example, the control element 22 can be moved to the end position when a vehicle occupant is required to provide an input, when such input is necessary, and / or is expected. Alternatively or additionally, the system can move the control element 22 back to its initial position when an input has been made or completed, and / or when no input has been provided by the user for a defined period of time, thus indicating an unintended activation.

[0034] In a further development, the input device 20 can include a lighting device or backlighting. For example, the lighting device can illuminate the control element 22 and / or the area between the control element 22 and the receiving element 28 and / or the area between two or more control elements 22. The lighting device can be designed, for example, as an LED, light guide, or luminous surface. Alternatively or additionally, lighting can be arranged in the receiving element 28.

[0035] In an alternative embodiment, additional electronics can be arranged or integrated in or beneath the control element 22. For example, electrode surfaces can be applied. This allows, for instance, the integration of touch sensors close to the surface. In a further development, the control element 22 itself can be designed as a printed circuit board (PCB) with electronics and / or sensors and / or piezoelectric motors to implement, for example, haptic feedback, illumination, or even simple displays for showing dynamic content, icons, etc., on the surface.

[0036] In a further development, the piezoelectric motor 26 can be controlled to generate feedback via a high frequency. In other words, the piezoelectric motor 26 can be controlled to generate a vibration and thus, in particular, to generate haptic feedback for a user via a high frequency.

[0037] Fig. Figure 2 shows a schematic representation of an input device 20 according to an embodiment of the present invention. The input device 20 is configured for inputting a command. The input device 20 can, for example, be arranged in a vehicle, for instance according to Fig. 5. The input device 20 according to Fig. 2 is according to the input device 20 according to Fig. 1. The input device 20 has according to Fig. 1 the control element 22, the piezo motor 26 with the threaded rod 27 for moving the control element 22 between the starting position and the end position and the receiving element 28.

[0038] In contrast to the input device 20 according to Fig. 1 indicates the input device 20 according to Fig. 2. An elastic layer 30 is further arranged on the receiving element 28 on a user-facing side 32 of the input device 20 such that at least part of the control element 22 is covered by the elastic layer 30. In its initial position, the elastic layer 30 forms a flat surface. In other words, the elastic layer 30 is flat in its initial position, so that no bulge or indentation of the elastic layer 30 is formed or will be formed by the control element 22. Thus, the elastic layer 30 is undeformed in its initial position, i.e., not deformed by the control element 22. Preferably, the elastic layer 30 can be stretched over the control element 22 in an undeformed state in its initial position. Preferably, this renders the control element 22 invisible or non-visible to a user in its initial position.The elastic layer 30 can be designed to be deformable when the control element 22 is moved into its end position. Deformation can occur, for example, in the end position of the control element 22 as shown in [reference]. Fig. 3 and / or Fig. 4. When the control element 22 is moved back from the end position to the starting position, the elastically deformable layer 30 can, in particular, deform back. Elastic deformation of the elastic layer 30 can, in particular, be an elongation of the elastic layer 30.

[0039] In an advantageous embodiment, the elastic layer 30 is attached to the receiving element 28. In particular, the elastic layer 30 is attached to a side 32 of the receiving element 28 facing the user. Specifically, the elastic layer 30 is attached to the user-facing surface 29 of the receiving element 28. For example, the elastic layer 30 can be attached to the receiving element 28 by means of a material-bonded connection. The material-bonded connection can, for example, be an adhesive bond. In this way, the elastic layer 30 can be attached to the receiving element 28, in particular by means of an adhesive bond. Furthermore, in a further development, the elastic layer 30 can be attached, at least partially, to the operating element 22.

[0040] In one exemplary embodiment, the area of ​​the elastic layer 30 arranged above the control element 22 can be designed as a touch-sensitive layer. Preferably, input can be made by a user by touching the touch-sensitive layer. For example, touch-sensitive textile fibers can be incorporated into the elastic layer 30. In a further development, one or more proximity sensors 50 can be integrated into the elastic layer 30. The one or more proximity sensors 50 can, for example, be configured according to Fig. 1. Be trained.

[0041] In a further development, alternatively or additionally to the according to Fig. The lighting described in section 1 can be provided, for example, by means of luminous filaments arranged or implemented in the elastic layer 30. Alternatively or additionally, lighting can be provided, for example, by means of luminous filaments arranged in the flexible or elastic layer 30.

[0042] In an alternative embodiment, the elastic layer 30 can be arranged on the receiving element 28 and on the second surface 25 of the control element 22 facing away from the user, wherein the elastic layer 30 is deformable when the control element 22 is moved into its end position. This means that the elastic layer 30 may not be visible, or only visible in the small gap between the control element 22 and the receiving element 28.

[0043] Fig. Figure 3 shows a schematic representation of an input device 20 according to an embodiment of the present invention. The input device 20 is configured for inputting a command. The input device 20 can, for example, be arranged in a vehicle, for instance according to Fig. 5. The input device 20 according to Fig. 3 is according to the input device 20 according to Fig. 1 and / or Fig. 2. The input device 20 has according to Fig. 1 and / or Fig. 2 the control element 22, the piezo motor 26 with the threaded rod 27 for moving the control element 22 between the starting position and the end position, and the receiving element 28. In this advantageous embodiment, the input device 20 further comprises the elastic layer 30 according to Fig. 2. Alternatively, the input device 20 can also be without an elastic layer according to Fig. exhibit 1.

[0044] In contrast to the input device 20 according to Fig. 1 and / or Fig. 2 is the input device 20 according to Fig. 3 in the end position. The control element 22 is extended in the end position. The control element 22 is extended in the end position such that it protrudes at least partially beyond the receiving element 28. This results in a bulge from the receiving element 28 in the end position. In other words, in an alternative embodiment, the control element 22 can be extended or raised relative to the receiving element 28 in the end position. In this advantageous embodiment, the piezoelectric motor 26 moves the threaded rod 27 in a vertical direction. Advantageously, this also moves the control element 22 in a vertical direction. In other words, the piezoelectric motor 26 moves the control element 22 in a vertical direction. Alternatively, the control element 22 can be, see Fig. 4, will be lowered.

[0045] In this alternative embodiment, the elastic layer 30 can form a bulge in its final position, the bulge being particularly capable of assuming the shape of the control element 22. In other words, the elastic layer 30 is deformed in its final position so that a bulge is formed by the control element 22. Preferably, this makes the shape of the control element 22 visible to a user through the elastic layer 30 in its final position.

[0046] A function for entering a command using the input device 20 can be activated, in particular, when the control element 22 is in its end position. In other words, the function for activating an input according to Fig. 3 is activated because the control element 22 is in the end position.

[0047] Preferably, pressure applied to the control element 22 can be measured. In particular, a command can be entered by means of pressure on the control element 22. In other words, a command can be given via the input device by applying pressure to the control element 22. Advantageously, this pressure can be measured. For example, a classic push button, a pressure sensor, a piezoelectric sensor, an electroactive polymer, optical, resistive, or other suitable sensors can be used as a sensor for detecting the pressure applied by the user.

[0048] In a further development, the input device 20 can be equipped with a sensor 50 according to Fig. 1 and / or Fig. 2. The sensor 50 is configured to detect when a user approaches the input device 20. In other words, a sensor 50 can detect when a user approaches. When the sensor 50 detects that a user, in particular a hand, one or more fingers, is approaching, the control element 22 is moved to its end position by means of the piezoelectric motor. The sensor 50 can also be configured to detect when a user moves away from the input device 20. In other words, the sensor 50 can also detect when the user moves away from the control element 22 and thus away from the input device 20. When the sensor 50 detects that the user is moving away, the control element 22 can be moved back to its initial position. Alternatively or additionally, the control element 22 can be moved to its end position when user input is expected.The control element 22 can be moved back to its starting position, in particular by means of the piezo motor 26.

[0049] In other words, the input device 20 can be designed as a push button, which in its final position either protrudes from the receiving element 28 or retracts when operation by a user is necessary or desired. In the initial state, the area in which the push button or input device 20 is located is a flat surface.

[0050] In other words, the morphing of the control element 22 into or out of the surface is based on a piezoelectric motor 26 located below the surface to be deformed or the elastic layer 30, which can pull the correspondingly shaped control element 22 downwards or push it upwards, thereby deforming the elastic layer 30. The elastic layer 30 can, for example, be designed as a decorative layer, such as a textile covering, synthetic leather, or other suitable materials.

[0051] The elastic layer 30 must be designed to be sufficiently elastic and have a sufficient restoring force to be able to reproduce the desired degree of deformation, in particular depending on the dimensions of the control element 22 and the travel path of the control element 22, without damage and to form a smooth, wrinkle-free surface again when the control element 22 is retracted.

[0052] In an alternative embodiment, the area of ​​the elastic layer 30 arranged above the control element 22 can be designed as a touch-sensitive layer. Preferably, input can be made by touching the touch-sensitive layer. For example, touch-sensitive textile fibers can be incorporated into the elastic layer 30.

[0053] In a further development, the control element 22 can provide haptic feedback. For example, the control element 22 can vibrate, especially in different vibration patterns. For this purpose, the piezoelectric motor 26 can be controlled with a corresponding frequency.

[0054] Fig. Figure 4 shows a schematic representation of an input device 20 according to an embodiment of the present invention. The input device 20 is configured for inputting a command.
