Hereinafter, exemplary embodiments of the invention will be described in detail with reference to the accompanying drawings.

<FIG> and <FIG> are schematic front and rear views illustrating a vehicle display device according to a first embodiment of the invention.

A vehicle display device <NUM> illustrated in <FIG> and <FIG> is located between a driver seat and a passenger seat in a cockpit. The vehicle display device <NUM> includes a display <NUM>, a knob <NUM>, a guide rail <NUM>, and a guide part <NUM>.

A basic concept of the vehicle display device <NUM> is a structure in which the knob <NUM> and the display <NUM> are interlocked with each other, and the display <NUM> switches and displays images for functions for various pieces of vehicle operation information according to left-right movement of the knob <NUM>.

In this case, since the display <NUM> is located on a center fascia as a large screen, it is difficult to provide a space in which surrounding electronic units are arranged. Thus, instead of an existing physical button having a function for the vehicle operation information, the display <NUM> displays the corresponding function as a widget image.

Accordingly, the display <NUM> may improve intuitiveness and operability by reducing a depth and an operation step of a menu for the corresponding function displayed as a widget.

The knob <NUM> may be electrically interlocked with the display <NUM> to selectively operate various functions of the display <NUM> according to the left-right movement. This knob <NUM> has a structural mechanism that may slide at a lower end of the display <NUM>.

The guide rail <NUM> provides a movement path of the knob <NUM>. In this case, the guide rail <NUM> divides a plurality of functional areas that are interlocked with the widgets of the functions displayed on the display <NUM>. Here, the display <NUM> switches and displays images for the respective functions for the vehicle operation information whenever the knob <NUM> is located in the functional areas.

The guide rail <NUM> may include a plurality of position sensors <NUM> arranged at regular intervals in a lengthwise direction and arranged in the respective functional areas.

Here, the position sensors <NUM> detect a location of the knob <NUM> when the knob <NUM> moves leftward or rightward in the lengthwise direction of the guide rail <NUM> and transmit the detected data to an electronic control unit (ECU) <NUM>.

The ECU <NUM> may compare reference data with the detected data of the knob <NUM> received from the position sensors <NUM> and control, on the basis of the compared value, the display <NUM> to display the widget of the corresponding function as an image.

The guide part <NUM> has a function of automatically guiding the location of the knob <NUM> in a state in which magnets having different polarities are alternately arranged in the lengthwise direction of the guide rail <NUM>.

<FIG> is a cross-sectional view taken along line A-A' of <FIG>, <FIG> is an enlarged view illustrating portion B of <FIG>, <FIG> is an enlarged view illustrating portion C of <FIG>, <FIG> is a schematic exemplary view illustrating a state in which a location of a knob is corrected due to an action of an attractive force and a repulsive force of a magnetic field, and <FIG> is a schematic cross-sectional view illustrating a structure of a ball plunger.

Referring to <FIG>, the guide part <NUM> includes a first magnet <NUM> and a second magnet <NUM>.

The first magnet <NUM> is disposed in each functional area of the guide rail <NUM>.

The second magnet <NUM> is disposed near the first magnet <NUM>, and the polarity of a portion of the second magnet <NUM> in contact with the knob <NUM> is different from that of the first magnet <NUM>. Here, the knob <NUM> includes a magnetic body <NUM> in which a section in contact with the guide part <NUM> has a polarity different from that of the first magnet <NUM> and equal to that of the second magnet <NUM> so that an attractive force acts between the first magnet <NUM> and the magnetic body <NUM> and a repulsive force acts between the second magnet <NUM> and the magnetic body <NUM>.

For example, as illustrated in <FIG>, an N pole of the first magnet <NUM> is located in contact with the magnetic body <NUM> of the knob <NUM>. Here, the polarity of a portion the magnetic body <NUM> of the knob <NUM> in contact with the first magnet <NUM> is an S pole. In contrast, an S pole of the second magnet <NUM> is located in a section in contact with the S pole of the magnetic body <NUM>. Thus, the attractive force acts between the first magnet <NUM> and the magnetic body <NUM> of the knob <NUM>, and the repulsive force acts between the second magnet <NUM> and the magnetic body <NUM> of the knob <NUM>. Through this structural mechanism between the knob <NUM> and the guide part <NUM>, the location of the knob <NUM> is automatically corrected for each functional area. Thus, even when a user stops moving the knob <NUM> in the middle, the location of the knob <NUM> is recognized, and thus malfunction can be prevented.

The guide part <NUM> may further include a cover plate <NUM> having a first seating groove 143a on which the first magnet <NUM> is seated and a second seating groove 143b on which the second magnet <NUM> is seated.

The first and second seating grooves 143a and 143b are formed at regular intervals in the lengthwise direction of the guide rail <NUM>.

The first and second seating grooves 143a and 143b have one open surfaces, the open surface of the first seating groove 143a may be formed outside the guide rail <NUM>, and the open surface of the second seating groove 143b may be formed inside the guide rail <NUM>.

For example, the first and second seating grooves 143a and 143b may have an "S" structure in which different open surfaces are arranged.

In this case, the first seating groove 143a may have a size corresponding to the first magnet <NUM>, and the second seating groove 143b may have a size corresponding to the second magnet <NUM>. Here, it is preferable that the area of the first and second seating grooves 143a and 143b corresponds to the size of the first and second magnet <NUM> and <NUM>, and the area of the first and second seating grooves 143a and 143b may be relatively larger than the area of the first and second magnets <NUM> and <NUM>.

The guide part <NUM> includes a locking groove <NUM> that is recessed in each of the functional areas located at regular intervals in the lengthwise direction of the guide rail <NUM>, and the locking groove <NUM> may divide location areas of the knob <NUM> interlocked with the functions of the display <NUM>.

The knob <NUM> may include a ball plunger <NUM> of a ball spring type that is fitted in the locking groove <NUM> when the knob <NUM> moves in the lengthwise direction of the guide rail <NUM>.

The knob <NUM> may be spaced apart from the first magnet <NUM> by a preset predetermined gap. Here, the predetermined gap may correspond to the thickness of the first seating groove 143a on which the first magnet <NUM> is seated.

The magnetic body <NUM> of the knob <NUM> may not be in direct contact with the first magnet <NUM> but may be in contact with a closed surface of the first seating groove 143a. This is because, when the knob <NUM> moves, and when the knob <NUM> comes into direct contact with the first magnet <NUM>, the movement itself may be a problem due to the attractive force therebetween.

In contrast, when the knob <NUM> moves, the repulsive force acts between the magnetic body <NUM> and the second magnet <NUM>. Thus, in order to prevent the second magnet <NUM> from being separated to the outside due to the repulsive force, the second groove 143b has an open inner side and a closed outer side. In this case, the thickness of the second seating groove 143b may be greater than the thickness of the first seating groove 143a.

<FIG> are schematic views illustrating a change structure of a user interface (UI) according to an operation intention of the knob in the vehicle display device according to the first embodiment of the invention.

As illustrated in <FIG>, in the function widget <NUM>, the five functions are partitioned and displayed according to locations. This is merely one example, but the invention is not limited thereto, and in the function widget <NUM>, a plurality of N functions may be displayed.

<FIG> is an exemplary view illustrating a state in which a vehicle indoor temperature is adjusted by operating the knob in the vehicle display device according to the first embodiment of the invention.

Referring to <FIG>, the knob <NUM> moves to locations for the respective functions partitioned in the function widget <NUM> of the display <NUM> and serves as an arrow key so that the user may perform a desired function.

In this case, a liquid crystal display (LCD) <NUM> of the knob <NUM> displays an image of the function widget <NUM> interlocked with a current location of the knob <NUM>. Widgets for the functions displayed on the function widget <NUM> may be selected according to the left-right movement of the knob <NUM>, and detailed function execution for each function may be adjusted by rotating the knob <NUM>.

Here, the LCD <NUM> of the knob <NUM> basically displays a watch screen. The LCD <NUM> may display images for the various functions through location movement, rotation, pushing, and the like of the knob <NUM>.

<FIG> is an exemplary view illustrating a state in which the volume of a vehicle indoor sound source is adjusted by operating the knob in the vehicle display device according to the first embodiment of the invention.

Referring to <FIG>, the user moves the knob <NUM> leftward to adjust the volume of the vehicle indoor sound source. In this case, when a corresponding function image is displayed on the LCD <NUM>, the user may specifically operate the corresponding function by rotating the knob <NUM>.

<FIG> is an exemplary view illustrating a state in which an advanced smart cruise control (ASCC) function is performed by operating the knob in the vehicle display device according to the first embodiment of the invention.

Referring to <FIG>, when the knob <NUM> is moved leftward, an ASCC mode may be performed.

Here, the LCD <NUM> of the knob <NUM> displays an image related to the ASCC mode, and when the user rotates the knob <NUM> or pushes a button of the LCD <NUM>, the image of the LCD <NUM> is displayed in accordance with the corresponding function.

In this case, the corresponding function is displayed on the display <NUM> according to the operation of the knob <NUM>, and an integrated controller interlocked with the knob <NUM> performs the corresponding function.

<FIG> is an exemplary view illustrating a state in which a user-specified function is performed by operating the knob in the vehicle display device according to the first embodiment of the invention.

Referring to <FIG>, a shortcut key provided so that the user may quickly access a specified menu may be disposed in a specific area of the function widget <NUM>. Setting of the shortcut key may be implemented as desired by the user, and as illustrated, the shortcut key may be set to a navigation mode, a volume mode, a battery mode, a music mode, and a surround view monitor (SVM) mode.

In this case, when the knob <NUM> may be rotated or pushed in a state in which the knob <NUM> is moved to the corresponding shortcut key, the desired mode is performed.

Here, the screen layout of the display <NUM> or widget setting for each function may be conveniently controlled by the user in a setting mode.

<FIG> is a schematic view illustrating a vehicle display device according to a second embodiment of the invention, and <FIG> is an exemplary operation view illustrating a cross-section taken along line D-D' of <FIG>.

Referring to <FIG> and <FIG>, in a vehicle display device <NUM>, the location of a magnetic body <NUM> of a knob <NUM> is corrected due to an attractive force between the magnetic body <NUM> and a first magnet <NUM> of a guide part <NUM> arranged in each functional area of a display <NUM>.

The display <NUM> and an LCD <NUM> of the knob <NUM> are basically made as a capacitive type, and thus touch sensitivity is improved.

When the user allows a conductor (including a body and an object through which a current flows) to approach a preset proximity distance to grip the knob <NUM>, the LCD <NUM> or the display <NUM> recognizes this state and interlocks a system.

In this case, an infrared ray (IR) sensor or a time-of-flight (ToF) sensor <NUM> is provided at a lower end of the knob <NUM> to recognize a motion of the user.

Of course, the installation location of the IR sensor or the ToF sensor <NUM> is not limited to the lower end of the knob <NUM>, and the IR sensor or the ToF sensor <NUM> may be mounted at any location as long as the location is not obstructed by the front view angle.

Meanwhile, a grip part of a rim of the knob <NUM> may recognize a touch by being connected to an inner electrostatic touch sensor by applying a conductive material. In this case, a flexible printed circuit board (FPCB)-type touch film may be applied to an inner periphery of the rim of the knob <NUM>.

<FIG> illustrate a vehicle display device according to a third embodiment of the invention, not falling into the scope of claim <NUM>.

Referring to <FIG>, the vehicle display device <NUM> according to the third embodiment includes a display <NUM>, a knob <NUM>, a guide rail <NUM>, and a guide part <NUM>. Among the above components, a description of the components overlapping components in the above-described embodiment will be omitted.

The guide part <NUM> is spaced apart from an upper end of the guide rail <NUM> and provides a guide path in the form of a zigzag-curved shape in a lengthwise direction. Such a guide path divides a plurality of functional areas interlocked with the respective functions displayed on the display <NUM>.

The guide path of the guide part <NUM> is formed by alternately arranging a protrusion section and a recessed section having an inclined structure.

Here, it is preferable that the uppermost end of the recessed section is a fixed position of the knob <NUM> corresponding to the functional areas interlocked with the respective functions displayed on the display <NUM>.

Here, the knob <NUM> includes a spring roller <NUM> including a roller part 322a that is rotationally adjusted along the guide path of the guide part <NUM> and an elastic part 322b that is disposed at a lower end of the roller part 322a and may be vertically adjusted.

The guide path of the guide part <NUM> has a structure in which the protrusion section and the recessed section are alternately arranged as described above, and the protrusion section and the recessed section are formed in an inclined surface structure. The spring roller <NUM> of the knob <NUM> may slide down from a curved point to a fixed point of the inclined surface by a pushing force using spring elasticity. Therefore, the location of the knob <NUM> is automatically corrected to the functional area.

Meanwhile, the guide part <NUM> may include a locking groove <NUM> recessed in each of the functional areas located at regular intervals in the lengthwise direction of the guide rail <NUM>.

Here, the locking groove <NUM> divides location areas of the knob <NUM> interlocked with the functions of the display <NUM>.

The knob <NUM> may additionally include a ball plunger <NUM> of a ball spring type that is fitted in the locking groove <NUM> when the knob <NUM> moves in the lengthwise direction of the guide rail <NUM>.

The ball plunger <NUM> may fix the knob <NUM> to each of the functional areas linked to the functions of the display <NUM> with a predetermined force.

<FIG> is a schematic block diagram illustrating a vehicle display device according to a fourth embodiment of the invention, not falling into the scope of claim <NUM>.

Referring to <FIG>, a knob <NUM> may be wirelessly connected to a display <NUM> in an ultra-wide band (UWB) manner.

The UWB is a technology which calculates a distance between subjects by multiplying a signal arrival time between communication subjects by the speed of light using a ToF technology.

Unlike Wi-Fi and Bluetooth, the UWB uses a wide frequency band and may transmit a large amount of information with a high transmission speed using low power.

Positioning using the UWB technology has the advantage in that an error rate is as low as about <NUM> centimeters, transmittance to an obstacle is high, and the positioning is not affected by other signals such as Wi-Fi.

Accordingly, in a state in which the display <NUM> and the knob <NUM> are wirelessly connected in the UWB manner, integrated control can be performed by the ECU <NUM>.

For example, when the knob <NUM> moves along a guide rail <NUM>, the display <NUM> interlocked with the knob <NUM> displays a widget for each of the functions interlocked with the location of the knob <NUM>.

When the user sets the displayed widget, the corresponding function may be performed according to a command of the ECU <NUM>.

<FIG> are schematic views illustrating a vehicle display device according to a fifth embodiment of the invention, not falling into the scope of claim <NUM>.

Referring to <FIG>, a vehicle display device <NUM> is located between the driver seat and the passenger seat in a cockpit. The vehicle display device <NUM> includes a display <NUM>, a knob <NUM>, a guide rail <NUM>, and a power supply unit <NUM>.

A basic concept of the vehicle display device <NUM> is a structure in which the knob <NUM> and the display <NUM> are interlocked with each other, and the display <NUM> switches and displays images for the functions for various pieces of vehicle operation information according to left-right movement of the knob <NUM>.

In this case, as the display <NUM> is located on a center fascia as a large screen, it is difficult to provide a space in which surrounding electronic units are arranged. Thus, instead of an existing physical button having a function for the vehicle operation information, the display <NUM> displays the corresponding function as a widget image.

The knob <NUM> may be electrically interlocked with the display <NUM> to selectively operate the various functions of the display <NUM> according to the left-right movement. This knob <NUM> has a structural mechanism that may slide at a lower end of the display <NUM>.

The guide rail <NUM> provides a movement path of the knob <NUM>. In this case, the guide rail <NUM> divides a plurality of functional areas that are interlocked with the widgets of the functions displayed on the display <NUM>.

Here, the display <NUM> switches and displays images for the respective functions for the vehicle operation information whenever the knob <NUM> is located in the functional areas.

The power supply unit <NUM> supplies power to the display <NUM> and the knob <NUM>.

The knob <NUM> may include a ground pin <NUM> electrically connected to a ground part <NUM> of the power supply unit <NUM>.

The guide rail <NUM> includes a plurality of position sensors <NUM> arranged at regular intervals in a lengthwise direction and arranged in the respective functional areas.

The position sensor <NUM> may detect a location of the knob <NUM> through the ground pin <NUM> to transmit the detected location to the ECU <NUM>.

A lower end of the ground pin <NUM> may be fixed to an upper end of the knob <NUM>, and an upper end of the ground pin <NUM> may be in contact with the ground part <NUM> of the power supply unit <NUM> while physically having a degree of freedom.

A partial section of a portion of the ground pin <NUM>, the portion being in contact with the ground part <NUM> of the power supply unit <NUM>, may be formed in a curved shape.

When the knob <NUM> moves, the ground pin <NUM> may come into contact with the ground part <NUM> of the power supply unit <NUM> while being elastically deformed.

The ground part <NUM> of the power supply unit <NUM> may have a pin locking section 541a that is recessed at each portion corresponding to one of the functional areas located at regular intervals in the lengthwise direction of the guide rail <NUM>.

Here, the pin locking section 541a may be in contact with the ground pin <NUM> of the knob <NUM> and divide location areas of the knob <NUM> interlocked with the respective functions of the display <NUM>.

The display <NUM> may switch and display images for the respective functions for the vehicle operation information whenever the knob <NUM> is located in the functional areas.

<FIG> are schematic views illustrating a vehicle display device according to a sixth embodiment of the invention, not falling into the scope of claim <NUM>.

First, referring to <FIG> and <FIG>, a vehicle display device <NUM> includes a display <NUM>, a knob <NUM>, and a drive control unit <NUM>.

The display <NUM> and the knob <NUM> may be electrically interlocked with each other, and thus the user may selectively operate the corresponding function of the display <NUM> through left-right movement, rotation, and pushing of the knob <NUM>.

The drive control unit <NUM> controls the display <NUM> to display the corresponding function according to the location movement of the knob <NUM>.

Here, the drive control unit <NUM> includes a guide rail <NUM>, a position sensor <NUM>, and a controller <NUM>.

The guide rail <NUM> may provide a left-right movement path of the knob <NUM> and have components embedded therein and related to electronic units. Accordingly, the guide rail <NUM> may be covered with a separate cover forming an external shape.

The position sensors <NUM>, which are photo sensors, are arranged in the guide rail <NUM> at regular intervals to detect the location of the knob <NUM>.

The controller <NUM> may compare a preset data value with a value of the location of the knob <NUM> detected by the position sensor <NUM> and control, according to a result value of the comparison, the display <NUM> to display the corresponding function. In this case, the controller <NUM> may perform the function of the ECU <NUM> itself or may be connected to the ECU <NUM>.

Meanwhile, the knob <NUM> may store a graphical user interface (GUI) by applying a flash memory <NUM> and a graphic integrated circuit (IC) <NUM> and transmit the stored (preset) GUI according to a signal state.

Next, referring to <FIG>, the knob <NUM> may be wirelessly connected to the display <NUM> in an ultra-wide band (UWB) manner.

For example, when the knob <NUM> moves along the guide rail <NUM>, the display <NUM> interlocked with the knob <NUM> displays a widget for each of the functions interlocked with the location of the knob <NUM>.

According to the invention, in a vehicle display device, a sliding knob and a display are integrated, and thus the degree of freedom of a slimmed cockpit room can be secured, and intuitive operation convenience can be realized.

In particular, as one knob is moved in a left-right direction, a display menu can be efficiently selected through a corresponding interlocking operation, and as operation steps are reduced, intuitiveness and operability can be improved.

Moreover, a location recognition rate of the knob can be improved by forming a guide part that corrects the location of the sliding knob.
