[0051] By referring to the following Figure 1 The advantages and features of the present invention and the methods for achieving these advantages and features will become apparent from the detailed description of the embodiments. However, the present invention is not limited to the embodiments described below, but will be implemented in various forms, and these embodiments only make the disclosure of the present invention more complete.

[0052] The embodiments are provided to fully inform those skilled in the art of the scope of the present invention, to which the present invention belongs, and to which the present invention is defined by the description of the appended claims. At the same time, the terms used in this specification are intended to describe the embodiments and are not intended to limit the present invention. In this specification, the singular also includes the plural, unless specifically stated otherwise in the phrase. The terms "comprise" or "include" as used herein do not exclude the presence or addition of one or more other components, steps, operations and / or elements other than the components, steps, operations and / or elements described above.

[0053] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0054] First embodiment

[0055] Figure 1 and Figure 2 1 and 2 are schematic front and rear views showing a vehicle display device according to a first embodiment of the present invention.

[0056] According to the first embodiment of the present invention Figure 1 and Figure 2 The vehicle display device 100 is shown to be located between a driver's seat and a passenger seat in a cockpit. The vehicle display device 100 includes a display 110, a knob 120, a guide rail 130, and a guide portion 140.

[0057] The basic concept of the vehicle display device 100 is a structure in which the knob body 120 and the display 110 are interlocked with each other, and the display 110 switches and displays images for functions of various vehicle operation information according to left and right movement of the knob body 120 .

[0058] In this case, since display 110 is located as a large screen in the center fascia, it is difficult to provide space for surrounding electronic units. Therefore, instead of existing physical buttons with functions for vehicle operation information, display 110 displays the corresponding functions as widget images.

[0059] Therefore, the display 110 can improve intuitiveness and operability by reducing the depth and operation steps of menus for corresponding functions (which are displayed as widgets).

[0060] The button body 120 can be electrically interlocked with the display 110 to selectively operate various functions of the display 110 according to left and right movement. The button body 120 has a structural mechanism that can slide at the lower end of the display 110.

[0061] The guide rail 130 provides a movement path for the knob body 120. In this case, the guide rail 130 divides a plurality of functional areas, which are interlocked with controls of functions displayed on the display 110. Here, as long as the knob body 120 is located in a functional area, the display 110 switches and displays an image of the corresponding function for vehicle operation information.

[0062] The guide rail 130 may include a plurality of position sensors 131 arranged at regular intervals along a length direction and arranged in respective functional areas.

[0063] Here, when the button body 120 moves leftward or rightward in the length direction of the guide rail 130 , the position sensor 131 detects the position of the button body 120 and transmits the detected data to the electronic control unit (ECU) 10 .

[0064] The ECU 10 may compare the reference data with the data of the detected knob body 120 received from the position sensor 131 and control the display 110 to display a control of a corresponding function as an image based on the comparison value.

[0065] In a state where magnets with different polarities are alternately arranged along the longitudinal direction of the guide rail 130 , the guide portion 140 has a function of automatically guiding the position of the button body 120 .

[0066] Figure 3 It is along Figure 2 The cross-sectional view taken along the straight line A-A' is Figure 4 It shows Figure 3 An enlarged view of part B, Figure 5 It shows Figure 3 An enlarged view of part C of Figure 6 is a schematic illustration showing a state in which the position of the button body is corrected due to the effects of the attractive force and the repulsive force of the magnetic field, Figure 7 is a schematic cross-sectional view showing the structure of a ball plunger.

[0067] refer to Figures 3 to 7 , the guide portion 140 includes a first magnet 141 and a second magnet 142 .

[0068] The first magnet 141 is provided in each functional area of ​​the guide rail 130 .

[0069] The second magnet 142 is disposed near the first magnet 141, and the polarity of the portion of the second magnet 142 that contacts the button body 120 is different from that of the first magnet 141. Here, the button body 120 may include a magnetic body 122 in which the portion that contacts the guide portion 140 has a polarity that is different from that of the first magnet 141 but the same as that of the second magnet 142, such that an attractive force acts between the first magnet 141 and the magnetic body 122, and a repulsive force acts between the second magnet 142 and the magnetic body 122.

[0070] For example, Figure 4 As shown, the north pole of the first magnet 141 is positioned so as to contact or be in contact with the magnetic body 122 of the button body 120. Here, the polarity of the portion of the magnetic body 122 of the button body 120 that contacts or is in contact with the first magnet 141 is the south pole. Conversely, the south pole of the second magnet 142 is positioned so as to contact or be in contact with the south pole of the magnetic body 122. Consequently, an attractive force acts between the first magnet 141 and the magnetic body 122 of the button body 120, while a repulsive force acts between the second magnet 142 and the magnetic body 122 of the button body 120. This structural mechanism between the button body 120 and the guide portion 140 allows the position of the button body 120 to be automatically corrected for each functional area. Therefore, even if the user stops moving the button body 120 midway, the position of the button body 120 can be identified, thereby preventing malfunctions.

[0071] The guide portion 140 may further include a cover plate 143 having a first seating groove 143 a on which the first magnet 141 is seated and a second seating groove 143 b on which the second magnet 142 is seated.

[0072] The first and second seating grooves 143 a and 143 b are formed at regular intervals in the length direction of the guide rail 130 .

[0073] The first seating groove 143a and the second seating groove 143b have an open surface, the open surface of the first seating groove 143a may be formed on the outside of the guide rail 130, and the open surface of the second seating groove 143b may be formed on the inside of the guide rail 130.

[0074] For example, the first seating groove 143 a and the second seating groove 143 b may have an “S” structure in which different open surfaces are arranged.

[0075] In this case, the first seating groove 143a may have a size corresponding to the first magnet 141, and the second seating groove 143b may have a size corresponding to the second magnet 142. Here, it is preferred that the areas of the first and second seating grooves 143a and 143b correspond to the sizes of the first and second magnets 141 and 142, and the areas of the first and second seating grooves 143a and 143b may be relatively larger than the areas of the first and second magnets 141 and 142.

[0076] The guide portion 140 includes a locking groove 144 recessed in each functional area positioned at regular intervals along the length direction of the guide rail 130 , and the locking groove 144 may partition a position area of ​​the button body 120 interlocked with a function of the display 110 .

[0077] The knob body 120 may include a ball plunger 121 of a ball spring type that fits into the locking groove 144 when the knob body 120 moves along the length direction of the guide rail 130 .

[0078] The button body 120 may be spaced apart by a preset predetermined gap from the first magnet 141. Here, the predetermined gap may correspond to a thickness of the first seating groove 143a on which the first magnet 141 is seated.

[0079] The magnetic body 122 of the button body 120 may not be in direct contact with the first magnet 141, but may be in contact with the closed surface of the first seating groove 143a. This is because when the button body 120 moves, and when the button body 120 and the first magnet 141 are in direct contact, the movement itself may become a problem due to the attraction between them.

[0080] Conversely, when the button body 120 moves, a repulsive force acts between the magnetic body 122 and the second magnet 142. Therefore, to prevent the second magnet 142 from separating 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 can be greater than the thickness of the first seating groove 143a.

[0081] Changed structure of the UI of the display (Example of each function operated by the button)

[0082] Figure 8 and Figure 9 1 is a schematic diagram showing a structure in which a user interface (UI) is changed according to an operation intention of a knob body in a vehicle display device according to a first embodiment of the present invention.

[0083] Reference Figure 8 and Figure 9 When the user operates the button body 120, the display 110 displays functions related to vehicle operation information as a UI.

[0084] In this case, five functions are divided according to positions in the function control 111 displayed at the lower end of the display 110. When the knob 120 moves to a position corresponding to each function divided in the function control 111, as the function control 111 interlocked with the knob 120 is activated, an image for the corresponding function is displayed on the display 110.

[0085] Figure 10 1 is an exemplary diagram showing a state in which each function is displayed on a display by operating a knob body in the vehicle display device according to the first embodiment of the present invention.

[0086] refer to Figure 10 , in the display 110 , the function controls 111 , the lower display 112 , and the upper display 113 basically display images for the area.

[0087] The function control 111 may display a plurality of functions related to vehicle operation information as control icons, and the lower display 112 and the upper display 113 may display detailed contents related to the function control 111 as images.

[0088] like Figure 10 As shown, five functions are divided and displayed according to positions in the function control 111. This is just an example, but the present invention is not limited thereto, and a plurality of N functions may be displayed in the function control 111.

[0089] Figure 11 1 is a schematic diagram illustrating a state in which the temperature inside a vehicle is adjusted by operating a knob body of the vehicle display device according to the first embodiment of the present invention.

[0090] refer to Figure 11 , the button body 120 moves to a position for a corresponding function (the functions are divided in the function control 111 of the display 110) and is used as an arrow key so that the user can execute a desired function.

[0091] In this case, the liquid crystal display (LCD) 127 of the knob body 120 displays an image of the function control 111 interlocked with the current position of the knob body 120. Controls for functions displayed on the function control 111 can be selected according to the left and right movement of the knob body 120, and detailed function execution of each function can be adjusted by rotating the knob body 120.

[0092] Here, the LCD 127 of the knob body 120 basically displays a watch screen. The LCD 127 can display images for various functions by positional movement, rotation, pushing, or the like of the knob body 120.

[0093] Figure 12 1 is an exemplary diagram showing a state in which the volume of a sound source in a vehicle is adjusted by operating a knob in the vehicle display device according to the first embodiment of the present invention.

[0094] refer to Figure 12 , the user moves the button body 120 to the left to adjust the volume of the sound source in the car. In this case, when the corresponding function image is displayed on the LCD 127, the user can specifically operate the corresponding function by rotating the button body 120.

[0095] Figure 13 1 is an exemplary diagram illustrating a state in which an Advanced Smart Cruise Control (ASCC) function is executed by operating a knob in the vehicle display device according to the first embodiment of the present invention.

[0096] refer to Figure 13 , when the button body 120 moves to the left, the ASCC mode can be executed.

[0097] Here, the LCD 127 of the knob body 120 displays an image related to the ASCC mode, and when the user rotates the knob body 120 or presses a button of the LCD 127 , an image of the LCD 127 is displayed according to a corresponding function.

[0098] In this case, a corresponding function is displayed on the display 110 according to the operation of the button body 120, and the integrated controller interlocked with the button body 120 performs the corresponding function.

[0099] Figure 14 1 is an exemplary diagram showing a state in which a user-specified function is executed by operating a knob body in the vehicle display device according to the first embodiment of the present invention.

[0100] refer to Figure 14 A shortcut key can be set in a specific area of ​​the function control 111. The shortcut key is used to allow the user to quickly access a specified menu. The shortcut key can be set according to the user's needs. As shown in the figure, the shortcut key can be set to navigation mode, volume mode, battery mode, music mode, and surround view monitor (SVM) mode.

[0101] In this case, when the button body 120 may be rotated or pushed in a state where the button body 120 moves to the corresponding shortcut key, a desired mode is executed.

[0102] Here, the screen layout of the display 110 or the control setting for each function may be conveniently controlled by the user in the setting mode.

[0103] The change structure of the UI of the display 110 is achieved by Figures 8 to 14 It is noted that it is not limited to the first embodiment and can be applied to all embodiments described in this specification.

[0104] Second embodiment

[0105] Figure 15 is a schematic diagram showing a vehicle display device according to a second embodiment of the present invention, Figure 16 is shown along Figure 15 An exemplary operation diagram of a cross-sectional view taken along the straight line D-D '.

[0106] Reference Figure 15 and Figure 16 In the vehicle display device 200 , due to the attraction between the magnetic body 221 of the button body 220 and the first magnet 241 of the guide portion 240 arranged in each functional area of ​​the display 210 , the position of the magnetic body 221 of the button body 220 can be corrected.

[0107] The display 210 and the LCD 223 of the button body 220 are basically made into a capacitive type, thereby improving touch sensitivity.

[0108] When the user allows a conductor (including a body and an object through which current flows) to approach a preset approach distance to hold the button body 220, the LCD 223 or the display 210 recognizes this state and interlocks the system.

[0109] In this case, an infrared (IR) sensor or a time-of-flight (ToF) sensor 250 is provided at a lower end of the button body 220 to recognize a user's motion.

[0110] Of course, the installation position of the IR sensor or ToF sensor 350 is not limited to the lower end of the button body 220, and the IR sensor or ToF sensor 350 can be installed at any position as long as the position is not obstructed by the front viewing angle.

[0111] At the same time, the grip portion of the edge of the button body 220 can be connected to the internal electrostatic touch sensor by applying a conductive material to recognize the touch. In this case, a flexible printed circuit board (FPCB) type touch film can be applied to the inner periphery of the edge of the button body 220.

[0112] Third embodiment

[0113] Figures 17 to 20 A vehicle display device according to a third embodiment of the present invention is shown.

[0114] Reference Figures 17 to 20 , the vehicle display device 300 according to the third embodiment includes a display 310, a knob body 320, a guide rail 330, and a guide portion 340. Descriptions of components that overlap with those in the above-described embodiment will be omitted.

[0115] The guide portion 340 is spaced apart from the upper end of the guide rail 330 and provides a guide path in a zigzag-like curved shape along the length direction. Such a guide path divides a plurality of functional areas that are interlocked with respective functions displayed on the display 310.

[0116] The guide path of the guide portion 340 is formed by alternately arranging protruding portions and recessed portions having an inclined structure.

[0117] Here, it is preferred that the uppermost end of the concave portion is a fixed position of the button body 320 , which corresponds to a functional area interlocked with each function displayed on the display 310 .

[0118] Here, the button body 320 includes a spring roller 322 including a roller part 322a rotationally adjustable along a guide path of the guide part 340 and an elastic part 322b provided at a lower end of the roller part 322a and vertically adjustable.

[0119] The guide path of guide portion 340 has a structure with alternating protrusions and recesses, as described above, forming an inclined surface. Using the spring's elastic force, spring roller 322 of knob body 320 slides downward from its bending point to its fixed point on the inclined surface. This automatically adjusts the knob body 320 to its functional area.

[0120] Meanwhile, the guide portion 340 may include a locking groove 341 recessed in each functional region positioned at regular intervals in the length direction of the guide rail 330 .

[0126] refer to Figure 21 , the button body 420 can be wirelessly connected to the display 410 in an ultra-wideband (UWB) manner.

[0127] UWB is a technology that uses ToF technology to calculate the distance between communicating objects by multiplying the signal arrival time between the communicating objects by the speed of light.

[0128] Unlike Wi-Fi and Bluetooth, UWB uses a wide frequency band and can transmit large amounts of information at high transmission speeds using low power.

[0129] The advantages of using UWB technology for positioning are that the error rate is as low as about 20 cm, the transmittance to obstacles is high, and positioning is not affected by other signals such as Wi-Fi.

[0130] Therefore, in a state where the display 410 and the knob 420 are wirelessly connected in the UWB manner, integrated control can be performed by the ECU 10 .

[0131] For example, when the knob body 420 moves along the guide rail 430 , the display 410 interlocked with the knob body 420 displays a control for each function interlocked with the position of the knob body 420 .

[0132] When the user sets the displayed controls, corresponding functions may be executed according to commands of the ECU 10 .

[0133] Fifth embodiment

[0134] Figures 22 to 251 is a schematic diagram showing a vehicle display device according to a fifth embodiment of the present invention.

[0135] Reference Figures 22 to 25 The vehicle display device 500 according to the fifth embodiment of the present invention is located between the driver's seat and the passenger seat in the cockpit. The vehicle display device 500 includes a display 510, a knob 520, a guide rail 530, and a power supply unit 540.

[0136] The basic concept of the vehicle display device 500 is a structure in which a knob body 520 and a display 510 are interlocked with each other, and the display 510 switches and displays images of functions for various vehicle operation information according to left and right movement of the knob body 520 .

[0137] In this case, since display 510 is located in the center as a large screen, it is difficult to provide space in which to arrange surrounding electronic units. Therefore, instead of existing physical buttons for functions of vehicle operation information, display 510 displays the corresponding functions as control images.

[0138] Therefore, the display 510 can improve intuitiveness and operability by reducing the depth and operation steps of menus for corresponding functions (which are displayed as widgets).

[0139] The button 520 can be electrically interlocked with the display 510 to selectively operate various functions of the display 510 according to left and right movement. The button 520 has a structural mechanism that can slide at the lower end of the display 510.

[0140] The guide rail 530 provides a movement path for the button body 520. In this case, the guide rail 530 divides a plurality of functional areas, which are interlocked with controls of functions displayed on the display 510.

[0141] Here, whenever the knob body 520 is located in the function area, the display 510 switches and displays images for respective functions of the vehicle operation information.

[0142] The power supply unit 540 supplies power to the display 510 and the button 520 .

[0143] The button body 520 may include a ground pin 522 electrically connected to the ground portion 541 of the power supply unit 540 .

[0144] The guide rail 530 includes a plurality of position sensors 531 arranged at regular intervals along a length direction and arranged in respective functional areas.

[0145] The position sensor 531 may detect the position of the button body 520 through the ground pin 522 to transmit the detected position to the ECU 10 .

[0146] The lower end of the ground pin 522 may be fixed to the upper end of the button body 520 , and the upper end of the ground pin 522 may be in contact with the ground portion 541 of the power supply unit 540 while having physical freedom.

[0147] A partial cross-section of a portion of the ground pin 522 may be formed in a bent shape, and the portion contacts the ground portion 541 of the power supply unit 540 .

[0148] When the button body 520 moves, the ground pin 522 may come into contact with the ground portion 541 of the power supply unit 540 while being elastically deformed.

[0149] The ground portion 541 of the power supply unit 540 may have a pin locking portion 541 a recessed at each portion corresponding to one of the functional areas located at regular intervals along the length direction of the guide rail 530 .

[0150] Here, the pin locking portion 541 a may contact the ground pin 522 of the button body 520 and partition a position area of ​​the button body 520 interlocked with various functions of the display 510 .

[0151] Whenever the knob body 520 is located in the function area, the display 510 may switch and display images for respective functions of vehicle operation information.

[0152] Sixth embodiment

[0153] Figures 26 to 28 1 is a schematic diagram showing a vehicle display device according to a sixth embodiment of the present invention.

[0154] First, refer to Figure 26 and Figure 27 The vehicle display device 600 includes a display 610 , a button body 620 and a driving control unit 640 .

[0155] The display 610 and the button body 620 can be electrically interlocked with each other, so the user can selectively operate the corresponding function of the display 210 by moving the button body 620 left and right, rotating, and pushing.

[0156] The driving control unit 640 controls the display 610 to display corresponding functions according to the position movement of the button body 620.

[0157] Here, the driving control unit 640 includes a guide rail 630 , a position sensor 631 , and a controller 641 .

[0158] The guide rail 630 may provide a left-right movement path of the knob body 620 and have components embedded therein and associated with the electronic unit. Therefore, the guide rail 630 may be covered by a separate cover forming an outer shape.

[0159] Position sensors 631 , which are optical sensors, are arranged at regular intervals in the guide rail 630 to detect the position of the button body 620 .

[0160] The controller 641 can compare the preset data value with the position value of the button body 620 detected by the position sensor 631, and control the display 610 to display the corresponding function according to the result of the comparison. In this case, the controller 641 can perform the functions of the ECU 10 itself or can be connected to the ECU 10.

[0161] Meanwhile, the button body 620 may store a graphical user interface (GUI) by using a flash memory 642 and a graphic integrated circuit (IC) 643 and transmit the stored (preset) GUI according to a signal state.

[0162] Next, refer to Figure 28 , the button body 620 can be wirelessly connected to the display 610 in an ultra-wideband (UWB) manner.

[0163] UWB is a technology that uses ToF technology to calculate the distance between communicating objects by multiplying the signal arrival time between the communicating objects by the speed of light.

[0164] Unlike Wi-Fi and Bluetooth, UWB uses a wide frequency band and can transmit large amounts of information at high transmission speeds using low power.

[0165] The advantages of using UWB technology for positioning are that the error rate is as low as about 20 centimeters, the penetration rate of obstacles is high, and positioning is not affected by other signals such as Wi-Fi.

[0166] Therefore, in a state where the display 610 and the knob 620 are wirelessly connected in the UWB manner, integrated control can be performed by the ECU 10 .

[0167] For example, when the button body 620 moves along the guide rail 630 , the display 610 interlocked with the button body 620 displays controls for each function interlocked with the position of the button body 620 .

[0168] When the user sets the displayed controls, corresponding functions may be executed according to commands of the ECU 10 .

[0169] According to the present invention, a slide knob body and a display are integrated in a vehicle display device, thereby ensuring a degree of freedom in a narrow cabin space and achieving intuitive operational convenience.

[0170] In particular, when a button body moves in the left-right direction, the menu can be effectively selected and displayed through corresponding interlocking operations, and since the number of operation steps is reduced, the intuitiveness and operability can be improved.

[0171] Furthermore, by forming a guide portion for correcting the position of the sliding button body, the position recognition rate of the button body can be improved.

[0172] In addition, since the button body and the display are connected by an elastically deformable ground pin, the problem of disconnection caused by connecting with a wire can be solved.

[0173] The present invention is not limited to the above-described embodiments, and various modifications and implementations may be made to the present invention without departing from the permissible scope of the technical spirit of the present invention.
