Description

Display devices and vehicles

[0001] The present invention relates to a retractable display device and a vehicle equipped with the same.

[0002] A vehicle is a device that drives in the direction desired by the user, and recently, it is equipped not only with an engine and wheels for driving but also with various devices for the user's safety and convenience.

[0003] Vehicle convenience features are driven by development motives related to driver convenience, such as providing infotainment (information + entertainment) functions to the vehicle, supporting partial autonomous driving functions, or helping to secure the driver's visibility, such as night vision or blind spots. Examples include active cruise control (ACC), smart parking assist system (SPAS), night vision (NV), head-up display (HUD), around view monitor (AVM), and adaptive headlight system (AHS).

[0004] In addition, vehicle safety features are technologies that ensure the safety of drivers and / or pedestrians, such as the lane departure warning system (LDWS), lane keeping assist system (LKAS), and autonomous emergency braking (AEB).

[0005] Instrument clusters, which were used to provide information about the vehicle's status, are becoming digitized and are increasingly being replaced by display devices. Additionally, the center fascia, located between the driver and passenger seats, which previously only had output functions, now functions as an input device with the addition of touch capabilities.

[0006] Displays not only output information but are also equipped with touch sensors to enable simultaneous touch input, allowing them to function as both output and input units; consequently, the size of display devices applied to vehicles is trending upwards.

[0007] While increasing the size of the display panel for ease of use is desirable, it occupies a large area when not in use, and if it takes up too much space when turned off, it can detract from the vehicle's interior design.

[0008] There is a need for a display device that can be pulled out only when necessary to provide a screen of sufficient size without compromising the vehicle's interior design elements.

[0009] The objective of the present invention is to provide a display device having a door capable of opening and closing an opening through which an inlet / outlet display module passes without power, and a vehicle equipped with the same.

[0010] A display device is provided that includes: a display module; a driving frame connected to the display module; a driving unit that slides the driving frame in a first direction and in a second direction opposite to the first direction; a door guide formed on the driving frame and having an inclined portion that curves in a third direction perpendicular to the first direction as it approaches the end of the first direction; a door panel positioned adjacent to the end of the first direction of the display module; and a door lever that includes a first arm having a first lever roller that moves along the door guide and a second arm that contacts the door panel, and rotates around a lever shaft between the first arm and the second arm as an axis, wherein when the driving unit slides the driving frame in the first direction, the lever roller of the door lever moves along the door guide in a fourth direction opposite to the third direction, and the second arm of the door lever moves the door panel in the third direction to switch to an open state.

[0011] The above door panel includes a door panel extended in the third direction; and a door back bracket extended in the second direction from the door panel, and

[0012] It may further include a second lever roller located at the end of the second arm and moving in the first direction or the second direction on the lower surface of the door back bracket.

[0013] The length of the first arm may be shorter than the length of the second arm.

[0014] The first arm and the second arm may extend obliquely from the lever shaft toward the fourth direction at a predetermined angle.

[0015] The above door guide may include a straight section; and an inclined section located in the first direction of the straight section and protruding in the third direction.

[0016] The above-mentioned inclined portion may include a locking portion in which the lever roller is caught and fixed at the first direction end.

[0017] It may include a curved section connecting the straight section and the inclined section.

[0018] The display module includes a rear plate located on the back and connected to the drive link, and the length of the first direction of the inclined portion may be equal to or shorter than the distance from the door panel to the rear plate.

[0019] The door elastic member that pulls the door panel in the third direction is further included, and the door lever can apply force to the door panel in a direction that resists the elasticity of the door elastic member when in a closed state.

[0020] The display module includes a first planar section, a second planar section, and a bendable part located between the first planar section and the second planar section, and the bendable part bends in the third direction when passing through the door panel and can be located in the first direction of the door panel.

[0021] A housing in which the display module, the driving unit, the door guide, the door panel, and the door lever are housed; and a panel opening formed in a first direction of the housing and through which the display module passes when moving in the first direction, wherein the door panel can open and close at least a portion of the panel opening.

[0022] The panel opening may include a first opening corresponding to the thickness of the display module and through which the display module passes; and a second opening located in the third direction from the first opening and through which the door panel opens and closes.

[0023] The third direction size of the second opening may be larger than the thickness of the backplate located on the back surface of the display module and connected to the drive link.

[0024]

[0025] The size of the second opening may be smaller than that of the first opening in the fourth direction perpendicular to the first direction and the third direction.

[0026] The device comprises a dashboard having a panel opening formed therein; and a display device mounted inside the dashboard, wherein the panel opening may include a first opening corresponding to the thickness of the display module; and a second opening located in the third direction from the first opening, through which the door panel opens and closes.

[0027] The display device of the present invention can withdraw the display module when needed and store it when not in use.

[0028] In addition, the display device of the present invention can be covered so that the driving part is not exposed to the outside when stored, thereby providing excellent aesthetics and preventing the ingress of foreign substances.

[0029] In addition, the display device of the present invention has the advantage of a simple configuration as it does not require a separate motor for the door and is synchronized with the movement of the display module.

[0047] FIG. 1 is a drawing showing the exterior of a vehicle according to an embodiment of the present invention, and FIG. 2 is a drawing showing the interior of a vehicle according to an embodiment of the present invention.

[0048] The vehicle includes wheels (70) that rotate by a power source and may be constructed with glass that is open at the front so that a user located inside can see the front. The interior of the vehicle may include a steering input device (51) for controlling the direction of travel of the vehicle, and an acceleration input device (53) and a brake input device (57) for controlling the speed of the vehicle.

[0049] The steering input device (51) can receive input regarding the direction of travel of the vehicle (10) from the user. The steering input device (51) is preferably formed in the shape of a steering wheel so that steering input is possible by rotation. According to an embodiment, the steering input device may be formed in the shape of a touch screen, a touch pad, or a button.

[0050] The acceleration input device (50) can receive input from a user for accelerating the vehicle (10). The brake input device (57) can receive input from a user for decelerating the vehicle (10). The acceleration input device (53) and the brake input device (57) are preferably formed in the form of pedals. According to an embodiment, the acceleration input device or the brake input device may be formed in the form of a touch screen, a touch pad, or a button.

[0051] The vehicle may operate in a manual mode in which the user controls the vehicle's driving direction by operating the steering device, acceleration input device, and brake input device, or it may switch to an autonomous driving mode based on information, data, and information about surrounding objects provided by external devices, allowing the driving system to perform autonomous driving without user operation.

[0052] It may include a communication device to receive information and data provided from an external device. The communication device is a device for performing communication with an external device. Here, the external device may be another vehicle, a mobile terminal, or a server.

[0053] A communication device may include at least one of a transmitting antenna, a receiving antenna, an RF (Radio Frequency) circuit capable of implementing various communication protocols, and an RF element to perform communication.

[0054] The communication device may include a short-range communication unit, a location information unit, a V2X communication unit, an optical communication unit, a broadcast transmission and reception unit, and a processor.

[0055] The vehicle may include an object detection device to obtain information about surrounding objects.

[0056] Objects may include lanes, other vehicles, pedestrians, motorcycles, traffic signals, lights, roads, structures, speed bumps, terrain features, animals, etc. Object detection devices may include cameras, radar, lidar, ultrasonic sensors, and infrared sensors.

[0057] The driving system is a system that controls various operations of the vehicle and can operate in autonomous driving mode; in manual mode, the driving system can assist the user with auxiliary operations.

[0058] The driving system may include a processor and can control the power source and wheels (70) based on information received from an object detection device and a communication device.

[0059] The vehicle may include a user interface device for communicating with a user. The user interface device may receive user input and provide the user with information generated in the vehicle (10).

[0060] The user interface device may include an input unit, an internal camera, a bio-sensing unit, an output unit (25), and a processor. Depending on the embodiment, the user interface device may include additional components other than the components described, or may not include some of the components described.

[0061] The output unit (25) is intended to generate output related to sight, hearing, or touch. The output unit (25) may include at least one of a display device and an audio output unit, and may display graphics corresponding to various information through the display device. The display device may include a display panel comprising one of a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), and a flexible display.

[0062] As display panels become thinner and their shapes become more diverse, the size of the output section can increase and its placement location can become more varied. Additionally, the display device can form a layer with a touch sensor that recognizes touch, allowing the output section to function as an input section as well.

[0063] Display devices can be installed in locations traditionally used for inputs, such as the steering wheel, instrument panel, seats, pillars, doors, center console, headlining, sun visor, and windshield. Accordingly, the size of display devices applied to vehicles is trending upwards.

[0064] While it is good for the size of the display panel (410) to increase for ease of use, if it takes up a large area when not in use and takes up too much area when turned off, it can be a factor that harms the interior design of the vehicle.

[0065] There is a need for a display device that can be pulled out only when necessary to provide a screen of sufficient size without compromising the vehicle's interior design elements.

[0066] Accordingly, the present invention provides a display device that can reduce the size of the exposed screen by being pulled out when necessary and retracted when unnecessary. Although the display device of the present invention is described based on being mounted in a vehicle, it may also be installed in moving driving devices other than vehicles and in fixed locations.

[0067] FIG. 3 is a perspective view illustrating a first state of a display device (1000) according to one embodiment of the present invention, and FIG. 4 is a perspective view illustrating a second state of a display device (1000) according to one embodiment of the present invention.

[0068] FIG. 5 is a perspective view illustrating a third state of a display device (1000) according to an embodiment of the present invention. FIG. 3 to FIG. 5 are perspective views taken obliquely from the upper side, and the lower left corner of the drawing is the front, and the front can be described as the first direction below.

[0069] The display device (1000) of the present invention may include a base module (100) fixed to a vehicle, etc. and a display module (400) movable on the base module (100). The display module (400) may include a flexible display panel (410) and may be bent and deformed as shown in FIGS. 4 and 5.

[0070] The display module (400) includes a first planar section (401) and a second planar section (402) that maintain a flat state, and may include a variable section (403) located between them. The planar section located in the first direction is called the first planar section (401), and the planar section located in the opposite direction is called the second planar section (402).

[0071] To implement the variable portion (403), the display module (400) may use a flexible display panel (410), such as an organic light-emitting diode panel capable of bending deformation, and the distinction between the first flat portion (401), the second flat portion (402), and the variable portion (403) may be determined by the back structure of the display panel (410).

[0072] The first planar section (401) and the second planar section (402) may include a flat back support structure for connecting a drive unit or guide structure that provides power for driving the display module (400). As shown in FIG. 3, the variable section (403) has a plurality of bending bars (423) extended in a horizontal direction that support the back of the display panel (410), and the angle between the bending bars (423) changes, and the curvature of the variable section (403) can change.

[0073] A housing (600, see FIG. 7) in which a display device (1000) is housed may be included, and the housing (600) may have a panel opening (610, FIG. 7) formed in a first direction of the display device (1000) through which a display module (400) can pass. The display device (1000) of the present invention is inserted and removed through the panel opening (610) and may optionally be exposed to a user.

[0074] The first state illustrated in FIG. 3 may be a state in which the display module (400) is housed inside a housing and is not in use. The second state illustrated in FIG. 4 is a state in which only a part of the display module (400), including the first planar portion (401), is exposed through the opening (610), and unlike the first state, the first planar portion (401) faces downward.

[0075] Here, the downward direction can be referred to as the second direction to distinguish it from the first direction mentioned above, and the second direction may be an angle close to 90° with respect to the first direction, but is not necessarily limited thereto, and means bending toward a direction different from the first direction.

[0076] The second state is a state in which the angle between the first planar part (401) and the second planar part (402) becomes smaller than in the first state, and the variable part (403) can move in the first direction so that the display module (400) is drawn out through the panel opening (610) as bending deformation occurs with a predetermined curvature.

[0077] The third state is a state in which the display module (400) is further withdrawn from the second state, resulting in a larger area facing the second direction. The second state in which only a portion of the display module (400) is withdrawn can be called a half screen, and the state in which the display module (400) is withdrawn to the maximum can be called a full screen. FIG. 6 is an exploded perspective view of a display device (1000) according to an embodiment of the present invention. The display device (1000) of the present invention may include a base module (100), a bending module (200), a slide module (300), and a display module (400).

[0078] The base module (100) is fixed to a vehicle, etc. and may include a guide wall (110) formed with rails (120, 130) to guide the movement of the bending module (200) and the slide module (300) as a driving part. A single guide wall (110) may be provided, but a pair may be arranged spaced apart laterally so that the display module (400) can move in a balanced manner.

[0079] A base plate (150) connecting the guide walls (110) forms the bottom surface of the display device (1000), and a first driving part (210) of the bending module (200) can be seated on the base plate (150).

[0080] The rails (120, 130) formed on the guide wall (110) may include a plurality of rails, and may be composed of a first guide wall (111) and a second guide wall (112) so that the plurality of rails (120, 130) do not overlap each other.

[0081] The display module (400) may include a bending module (200) and a slide module (300) for switching from a first state to a second state and from a second state to a third state, or vice versa.

[0082] The bending module (200) induces bending deformation of the variable part (403) by pushing the first flat part (401) of the display module (400) in a first direction to switch from a first state to a second state, while simultaneously changing the angle of the first flat part (401). The bending module (200) may include a rear plate (240), a rotating arm (230), a bending link (220), and a first driving part (210).

[0083] The rear plate (240) can be attached to the back surface of the first flat portion (401) of the display module (400). The rear plate (240) transmits the driving force of the bending module (200) to the first flat portion (401) through a pin-slot connection to the first flat portion (401) without interfering with the driving of the slide module (300).

[0084] When the bending module (200) is driven, the first planar portion (401) can be switched in the arrangement direction, and when the slide module (300) is driven, the display module (400) can be slid independently of the rear plate (240) to switch from the second state to the third state.

[0085] The rotating arm (230) can be extended at a predetermined angle with respect to the rear plate (240). When the rotating arm (230) rotates and the arrangement changes, the arrangement of the rear plate (240) changes, and the first state can be switched to the second state.

[0086] The rotating arm (230) may include a plurality of bending guide pins. A bending guide pin is a protrusion that is inserted into a bending guide rail (120) formed in a guide wall (110) and moves along the bending guide rail (120). It may include a rotating bearing or roller on the outer surface to facilitate movement along the bending guide rail (120).

[0087] The rotating arm (230) can be rotatably connected to one end of the bending link (220) through the rotating shaft (250), and the rotating arm (230) receives power from the first driving unit (210) through the bending link (220) and rotates independently of the bending link (220) and can induce bending deformation of the variable unit (403).

[0088] The first drive unit (210) can be fixed to the base module (100) and, referring to FIG. 10, may be composed of a first motor (211), a first gear block (212), a first ball screw (213), and a first drive nut (214). It may include a first gear block that transmits the rotational force of the first motor (211) to the first ball screw (213). When the first ball screw (213) extended in the first direction rotates, the first drive nut (214) through which the first ball screw (213) passes moves along the extension direction of the first ball screw (213), and the position in the first direction may change.

[0089] The first drive nut (214) is fastened to the drive frame (225), and the drive frame (225) may include a second slide pin (270) fastened to a slide rail (130) formed on the guide wall (110) so as to enable driving only in the first direction.

[0090] The slide rail (130) along which the second slide pin (270) moves can be configured to move along the same slide rail (130) as the first slide pin (370) that guides the first direction slide movement of the slide module (300).

[0091] The bending link (220) provides a driving force to the rotating arm (230) that moves in the first direction of the first driving unit (210) or in the third direction which is the opposite direction. The rotating arm (230) can convert the driving force of the first driving unit (210), which is provided in a linear direction, into rotational motion through the bending guide rail (120) and the bending guide pin.

[0092] The slide module (300) may include a first slide pin (370) that moves along a slide rail (130). The slide rail (130) may be formed on a second guide wall (112) so that the path of the slide pin (370) does not overlap with the drive of the rotating arm (230).

[0093] When the slide module (300) switches from the second state to the third state, it pushes the second flat portion (402) of the display module (400) in the first direction, causing the first flat portion (401) to move further in the second direction, thereby increasing the exposed area of ​​the display module (400).

[0094] The slide module (300) may include a slide frame (320) connected to the bending link (220) of the bending module (200) and the rotating shaft (250), and a second drive unit (310) fixed to the slide frame (320).

[0095] The display panel (410) is composed of a first flat section (401), a second flat section (402), and a variable section (403) located between them, and the bending module (200) provides power to the first flat section (401) and the slide module (300) provides power to the second flat section (402).

[0096] A panel cover (420) located on the back surface of a flexible display panel (410) may be composed of a flat cover (421, 422) on the back surface of a first flat portion (401) and a second flat portion (402), and a plurality of supporting bending bars (423) located on the back surface of a variable portion (403).

[0097] The variable portion (403) has a plurality of bending bars (423) extended in the horizontal direction that support the back surface of the display panel (410), and the angle between the bending bars (423) changes, and the curvature of the variable portion (403) can change. The bending bars (423) can be connected to adjacent bending bars (423) with a flexible material.

[0098] FIG. 7 is a perspective view illustrating an embodiment in which a display device (1000) according to one embodiment of the present invention is mounted inside a vehicle.

[0099] The display device (1000) of the present invention may include a housing (600) in which a display module (400) and a driving component (100-300) are accommodated. The display module (400) may be moved in and out from the inside of the housing (600) to the outside, and may include a panel opening (610) that is extended horizontally to allow the display module (400) to be moved in and out.

[0100] When the display module (400) is withdrawn, the first direction (D1) in which the drive frame (225) moves may be forward, facing the user, and the third direction (D3) and fourth direction (D4) may be downward and upward directions perpendicular to the first direction, or the first direction (D1) may be extended upward and the third direction may be extended horizontally. Depending on the arrangement of the display module (400), the direction of the panel opening (610) may also vary.

[0101] For convenience of explanation, the following description will be based on a display device (1000) mounted in a vehicle. The housing of the display device (1000) mounted in the vehicle may be a dashboard (600) located in front of the driver.

[0102] The display device (1000) can be inserted and removed through a panel opening (610) formed in the dashboard (600). In the first state, the display device (1000) is located inside the dashboard (600) so as not to be seen by the user as in FIG. 6 (a), and in the second and third states, it can be removed to switch to a state as in FIG. 6 (b).

[0103] As shown in FIG. 3, the display device (1000) of the present invention has the display module (400) positioned in a flat state in the first state, and to switch to the second state, the variable part (403) is bent, and the display module (400) is pulled forward and can be exposed to the outside through the panel opening (610) of the dashboard (600). In the third state, the display module (400) is driven, the bent position of the variable part (403) changes, and the area of ​​the display module (400) exposed to the front increases.

[0104] The display device (1000) of the present invention has a variable part that is bent and pulled out, and the thickness direction length of the panel opening (610) must be large so that a configuration such as a rear plate (240) coupled to the back surface of a display module (400) for sliding drive of the display device (1000) can pass through.

[0105] FIG. 8 is a drawing illustrating the location of the door and panel opening (610) of the dashboard (600) of a vehicle according to one embodiment of the present invention. As shown in FIG. 8 (a), the panel opening (610) is larger than the thickness of the display module (400), so there is a problem in that the driving structure on the rear of the display device (1000) and the interior of the dashboard (600) are visible.

[0106] Accordingly, the present invention may include a door module (500) including a door panel (510) that covers a panel opening (610) as shown in FIG. 8 (b). The door panel (510) of the present invention may cover only a part of the panel opening (610).

[0107] Since the display module (400) and the panel opening (610) must be aligned to enable the display module (400) to be inserted and withdrawn, the first direction (D1) end of the display module (400) can be positioned at the panel opening (610) even in the first state.

[0108] The door module (500) of the present embodiment is configured to cover only a part of the panel opening (610), and the display module (400) can penetrate the panel opening (610) while inserted into the panel opening (610).

[0109] The panel opening (610) may include a first opening (611) through which the display module (400) passes and a second opening (612) located in a third direction of the first opening (611). The second opening (612) may allow a rear plate (240) bending link and a hinge arm located on the back of the display module (400) to pass through.

[0110] The size of the first opening (611) corresponds to the width and thickness of the display module (400), and the second opening (612) may have the same width as the first opening (611), but may have a width corresponding to the width of the rear plate (240). The sizes of the first opening (611) and the second opening (612) may differ from each other. For convenience of explanation, the first opening (611) and the second opening (612) have been described separately, but the first opening (611) and the second opening (612) are connected to form a single opening (panel opening (610)).

[0111] The door panel (510) is not limited to the present embodiment, and the door module (500) may also be in a form that covers the entire panel opening (610).

[0112] The display device (1000) of the present invention may be mounted on a device other than the dashboard (600), and the housing forming the exterior of the display device (1000) may have a shape different from that of the dashboard (600), although it is the same in that it includes a panel opening (610) that is opened and closed by a door panel (510).

[0113] The door module (500) may include a door drive unit that moves the door panel (510) in a third direction to open the second opening (612) of the panel opening (610). The door drive unit may be moved vertically using a motor, but if a separate motor is added, the cost increases and the volume of the display device (1000) may increase.

[0114] In addition, since it must be driven simultaneously with the driving of the display module (400), it must operate in synchronization with the driving unit (210) that drives the display module (400).

[0115] In order to reduce volume and enable synchronization with the driving unit (210) of the display device (1000), the present invention can drive the door panel (510) by receiving power from the first driving unit that moves the display module (400) without an additional motor.

[0116] FIG. 9 is a perspective view illustrating a door module (500) of a display device (1000) according to one embodiment of the present invention, and FIG. 10 is an exploded perspective view illustrating a door module (500) of a display device (1000) according to one embodiment of the present invention.

[0117] The door module (500) of the present invention may include a door panel (510), a door lever (520), and a door guide (530) that guides the movement of the door lever (520).

[0118] As shown in FIG. 9, the door guide (530) is formed on the drive frame (225), and in this embodiment, the door guide (530) is formed on the lower side wall of the drive frame (225). It may also be configured in the form of a rail on the side wall of the drive frame (225).

[0119] The door guide (530) may include an inclined portion (531) protruding in a third direction (lower side in the drawing) at the end of the first direction (D1) and a straight portion (534) extending horizontally in a second direction from the top of the inclined portion (531).

[0120] The door lever (520) may include a first arm (521) extended in a second direction (D2) and a second arm (522) extended in a second direction (D2), which are rotatably fixed to a lever fixing part (540) fixed to a base (100) by a lever shaft (525). The first arm (521) and the second arm (522) may be straight or may have a V-shaped bend as shown in FIG. 9.

[0121] The end of the first arm (521) includes a first lever roller (523) that moves along the door guide (530), and when the first lever roller (523) is positioned on the inclined portion (531), the end of the second arm (522) can move in the opposite direction to the movement of the first lever roller (523).

[0122] The end of the second arm (522) is connected to the door panel (510) and may be hinge-coupled to the door panel (510), but the end of the second arm (522) moves in an arc around the lever shaft (525), so it may include a second lever roller (524) to allow it to slide on the door panel (510) so that only vertical force is transmitted to the door panel (510).

[0123] The second lever roller (524) may include a door back bracket (512) that protrudes horizontally in a second direction (D2) from the door panel (510). The second lever roller (524) moves in a first direction (D1) or a second direction (D2) along the lower surface of the door back bracket (512), and the vertical movement of the second arm (522) is transmitted to the drive of the door panel (510), while the horizontal movement induces a change in position on the back bracket (512).

[0124] A pair of door levers (520) are connected to the left and right sides of the door panel (510), and since the first lever rollers (523) both move along the door guide (530) formed on the drive frame (225), they can move simultaneously in synchronization.

[0125] The drive frame (225) having the door guide (530) formed in this embodiment moves in a first direction when the display module (400) is pulled out and moves the display module (400), so the movement of the door panel (510) can be synchronized with the movement of the display module (400).

[0126] FIGS. 11 to 14 are side views illustrating the driving process of a display device (1000) according to an embodiment of the present invention. Hereinafter, with reference to FIGS. 11 to 14, the driving method of the door module according to the movement of the display module (400) and the driving frame (225) will be explained step by step.

[0127] FIG. 11 illustrates a first state in which a display module (400) is arranged in a flat state, FIG. 14 illustrates a second state in which a variable part (403) is bent so that the first flat part (401) of the display module (400) faces forward, FIG. 12 and FIG. 13 illustrate the state of a door module (500) while transitioning from the first state to the second state.

[0128] As illustrated in FIG. 11, in the first state, the display module (400) is located inside the housing (dashboard (600)), and the door panel (510) covers the panel opening (610).

[0129] The drive frame (225) is located in the second direction (D2), and the first lever roller (523) of the door lever (520) is located at the end of the first direction (D1) of the door guide (530). The end of the first direction (D1) of the door guide (530) protrudes in the third direction, so the first arm (521) of the door lever (520) is pressed downward, and the second lever roller (524) located at the end of the second arm (522) pushes the door panel (510) upward to support it.

[0130] As shown in FIG. 11, the door lever (520) may have a length of the first arm (521) greater than that of the second arm (522), and since the protrusion amount of the inclined portion (531) of the door guide (530) is limited, the movement of the door panel (510) is made greater than the movement of the first arm (521).

[0131] As the first motor (211) begins to move, the drive frame (225) slides in the first direction (D1). As shown in FIG. 12, the first lever roller (523) moves past the inclined portion (531) of the door guide (530) to the straight portion (534), and the end of the first arm (521) moves upward (D4) and the second end moves downward (D3).

[0132] A door elastic member (550) that pulls the door panel (510) in a third direction (D3) may be further included. The door elastic member (550) provides elasticity in the direction of pulling the door panel (510) in a third direction to open the panel opening (610). The door lever (520) supports the door panel (510) in a direction that resists the elasticity of the door elastic member (550), and when the drive frame (225) moves in a first direction (D1), it rotates as shown in FIG. 12, and the door panel (510) moves in a third direction (D3) by the elasticity of the door elastic member (550).

[0133] When the door guide (530) is in the form of a rail, the movement of the door lever (520) is determined by the height of the door guide (530), but the door guide (530) of this embodiment is formed on the lower surface of the drive frame (225) and has an open bottom.

[0134] Accordingly, the end of the second arm (522) of the door lever (520) is pressed downward by the force of the door panel (510) being pressed in the third direction by the door elastic part (550), and the first arm (521) and the first lever roller (523) are attached to the door guide (530) and can move according to the height of the door guide (530).

[0135] Referring to FIG. 12, the area between the inclined section (531) and the straight section (534) may include a curved surface (533) for stable movement of the first lever roller (523). The end of the inclined section (531) may include a horizontally bent locking section (531) to stably fix the door lever (520) so that the door panel (510) can be maintained in a closed state in the first state.

[0136] The first lever roller (523) disengages from the locking part (531) and moves through the inclined part (531) to the straight part (534) when the drive frame (225) begins to move in the first direction (D1). The inclined part (531) has a steep slope and the horizontal length (d) may be longer than the vertical length (c).

[0137] The door panel (510) must move in a third direction before the rear plate (240), which passes through the second opening (612) covered by the door panel (510), comes into contact with the door panel (510). In the first state of FIG. 11, the length (d) of the first direction (D1) of the inclined portion (531) may be equal to or smaller than the distance (b) between the door panel (510) and the rear plate (240).

[0138] As shown in FIG. 13, the variable portion (403) of the display module (400) is bent so that the display module (400) protrudes outward from the dashboard (600), and the first lever roller (523) can move along the straight portion (534). However, since the length of the drive frame (225) is limited, the first lever roller (523) can be separated from the door guide (530) as shown in FIG. 14.

[0139] When the display module (400) switches from the second state to the first state, the lower side of the door guide (530) is open, so the first door lever (520) can easily come into contact with the straight portion (534) of the door guide (530) again and move along the door guide (530).

[0140] However, if the first lever roller (523) is disengaged from the door guide (530), and the door elastic part (550) pulls the door panel (510) further down than the state of FIG. 13, it may be difficult for the first lever roller (523) to re-enter the door guide (530).

[0141] Accordingly, the elasticity of the door elastic part (550) may be limited to limit the movement distance of the door panel (510) in the third direction (D3), or a door stopper (not shown) located at the bottom of the door panel (510) may be further included.

[0142] As described above, the display device (1000) of the present invention can withdraw the display module (400) when needed and store it when not in use.

[0143] In addition, the display device (1000) of the present invention can be covered so that the driving part is not exposed to the outside when stored, thereby providing excellent aesthetics and preventing foreign substances from entering.

[0144] In addition, the display device (1000) of the present invention has the advantage of being simple in configuration as it does not require a separate motor for the door module (500) and is synchronized with the movement of the display module (400).

[0145] The foregoing detailed description should not be interpreted restrictively in all respects and should be considered exemplary. The scope of the invention shall be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention are included within the scope of the invention.

[0146] Regarding various embodiments for implementing the present invention, descriptions that are redundant with those described above in the previous section on the best mode for carrying out the invention are omitted.

[0147] Since the present invention is applicable to display devices and vehicles in various fields, its industrial applicability is recognized.
