Description

Display device for vehicle

Technical Field

The present invention relates to a display device for a vehicle, and more particularly, to a display device which changes its position when necessary and is drawn in or out.

Background

The vehicle includes various input and output portions as means for a user interface. In the related art, the input unit is mainly constituted by a mechanical input unit such as a button, a knob, or a lever, but in recent years, there has been an increasing trend in vehicles in which a method that allows a user to input more intuitively has been applied from a voice input unit, a touch input unit, to a gesture input unit.

As the output portion, the most basic output portion is a cluster including an instrument panel that provides information about the speed, RPM, and fuel injection amount of the vehicle, but as the display technology improves and the functions of the vehicle become more accurate and diversified, vehicles including the display portion for outputting various contents are increasing.

In the related art, a small-sized liquid crystal panel for outputting sound is all of them, but in recent years, a large-sized display section for displaying navigation and a state of a vehicle is applied to a center instrument panel between a driver's seat and a passenger's seat. In addition, clusters of dashboards can also provide various information by applying displays that are not needle-like.

In addition, in order to enable a user to see main information without diverting the line of sight, HUDs (head up displays) that are output on a front windshield have been popular, so that a driver can confirm guidance of speed or navigation while looking ahead.

The display not only simply outputs information, but also has a touch sensor that can simultaneously perform touch input, and thus can simultaneously function as an output portion and an input portion, and thus the size of the display applied to a vehicle tends to be gradually larger.

However, since the dial including the dashboard and the center dashboard is located on the front surface of the vehicle, there is a problem that the front view is blocked when the size of the dial increases. In addition, in recent years, as the autopilot function has become advanced, there is also a case where the function of a dial panel that provides information to a user is not required or reduced at the time of autopilot, and thus the size of the dial panel is not unconditionally large.

Fig. 1 is a front perspective view showing a first state of a display device 10 of an embodiment of the present invention, and fig. 2 is a front perspective view showing a second state of the display device 10 of an embodiment of the present invention.

To realize a large screen in a limited space, the display device 10 of the present invention can be used. The display device 10 of the present invention can be provided at a position where space utilization can be improved by changing the position as necessary. For example, the display device 10 of the present invention may be used as a dial panel located on the front surface of a vehicle.

The display device 10 of the present invention may transition from the first state of fig. 1 to the second state of fig. 2. When switching from the first state to the second state, the display portion 100 can switch to a state of bending deformation as shown in fig. 2 while moving to the lower portion.

The display part 100 may include a display panel at a front surface thereof and a rear structure at a rear surface thereof to cover the display part 100. The display device 10 may include: a fixing unit 310 that fixes the display device 10 to a vehicle or a specific place (e.g., an instrument panel); and a driving part 330 and a moving unit attached to the rear structure of the display part 100 to change the position and shape of the display part 100.

The display panel may display graphic objects corresponding to various information. The display panel may include at least one of a liquid crystal display (liquid crystal display, LCD), a thin film transistor liquid crystal display (thin film transistor-liquid crystal display, TFT LCD), an organic light-emitting diode (OLED), a flexible display (flexible display), a three-dimensional display (3D display), and an electronic ink display (e-ink display). The display panel may be formed in a stacked structure with the touch input portion or formed as an integral type, thereby realizing a touch screen.

In order to realize the bending deformation as shown in fig. 2, a flexible display such as an organic light-emitting diode (OLED) may be used. Even if a flexible display panel is used, it is difficult to maintain rigidity in the case of bending deformation of all sections, and therefore, as shown in fig. 2, a part of sections is a variable portion B where bending deformation occurs, and planar portions F1, F2 may be included on upper and lower sides of the variable portion B.

When the overall curvature of the display unit 100 is changed, it is difficult to realize the combination with the moving units 320 and 340 for the deformation and the positional change of the display unit 100 shown in fig. 2. Further, the flexibility of the shape change increases due to the flexible structure, and thus, there is a possibility that the shape may be deformed into an unexpected shape.

The upper plane portion F1 moves only in the vertical direction based on the variable portion B, and the lower plane portion F2 protrudes obliquely forward while moving downward. The moving directions of the upper plane portion F1 and the lower plane portion F2 are different, and therefore, the curvature of the variable portion B located between the upper plane portion F1 and the lower plane portion F2 will change.

Fig. 3 is a rear perspective view showing a first state of the display device 10 of the embodiment of the present invention, and fig. 4 is a rear view showing the first state of the display device 10 of the embodiment of the present invention.

A structure for changing the position and shape of the display unit 100 and for mounting is provided on the back surface of the display unit 100 of the display device 10 of the present invention.

The structure may mainly include a fixed unit 310, a moving unit, and a driving part 330. The fixing unit 310 is a member for fixing the display device 10 to a vehicle or the like, and the driving part 330 is located at the fixing unit 310 and provides power for moving the moving unit relative to the fixing unit 310.

The moving unit is a member that moves by receiving power of the driving part 330, and is coupled with the plane parts F1, F2 of the display part 100 and guides movement and deformation of the display part 100. The moving unit may be mainly composed of a linear moving unit 320 coupled to the upper plane portion F1 and a curved moving unit 340 coupled to the lower plane portion F2.

The linear moving unit 320 may include a moving plate 321, a first front bracket 322, a rear bracket 323, a first guide block 324, and a second guide block 325. The curved moving unit 340 may include a lower arm 341, an upper arm 342, guide protrusions 343, 344, and a second front bracket 345.

The fixing unit 310 may include: a horizontal base 316 fixed to a bottom surface; and a vertical base 311 extending in a vertical direction from the horizontal base 316. The vertical base 311 may be formed with rails 312, 314, 315 for slidingly moving the moving units 320, 340, and the moving units 320, 340 may move with respect to the vertical base 311 and change the position of the display part 100.

As shown in fig. 3, the vertical bases 311 may be provided in pairs on the left and right, and the moving units 320 and 340 may be provided in pairs on the left and right. The display unit 100 can be stably moved without shaking by the moving units 320 and 340 provided in pairs on the left and right sides.

The mobile unit may include: a linear movement unit 320 for moving the upper plane F1 of the display unit 100 in the vertical direction; and a curved moving unit 340 that projects forward and moves when the lower plane portion F2 of the guide display portion 100 moves in the downward direction.

The linear moving unit 320 may move up and down along a linear rail formed at the vertical base 311, and the curved moving unit 340 may move along a curved rail.

The vertical base 311 may include a straight rail extending in a vertical direction, and may include: a first linear rail 314, shown in fig. 2, is positioned in front of the vertical base 311; and a second linear rail 315, shown in fig. 3 at the back side. The linear rail may be provided only on one side, but may be provided in pairs in front and rear in order to support the weight of the display unit 100 and move it without twisting.

The linear moving unit 320 may include: the first guide block 324 moves along the first linear rail 314 formed at the vertical base 311; and a second guide block 325 moving along the second linear rail 315.

The first guide block 324 may be fastened to the first front bracket 322, and the second guide block 325 may be fastened to the rear bracket 323. In order to move the first guide block 324 and the second guide block 325 at the same time, a moving plate 321 between the first front bracket 322 and the rear bracket 323 may be provided.

As shown in fig. 3, the moving plate 321 may be located inside in the direction opposite to each other as a pair of vertical bases 311. The moving plate 321 may be configured to form a predetermined interval with the vertical base 311.

Fig. 5 is a top view showing a moving unit of the display device 10 of the embodiment of the present invention, the moving plate 321 is not directly coupled with the linear rails 314, 315, but coupled with the first front bracket 322 and the rear bracket 323, and a space may be formed between the moving plate 321 and the vertical base 311.

As shown in fig. 5, the curved moving unit 340 may be located between the vertical base 311 and the moving plate 321. The curved moving unit 340 may include a lower arm 341, a lower portion of which lower arm 341 is coupled to a rear surface of the lower plane portion F2 and extends in an upper direction. The lower portion of the lower arm 341 is coupled to the lower flat surface portion F2 by a second front bracket 345 (fig. 3).

The curved moving unit 340 may further provide an upper arm 342 at an upper side of the lower arm 341. The upper arm 342 may include guide protrusions 343, 344 that move along the curved tracks 312, 326.

The lower arm 341 may receive the power of the driving part 330 and push the lower plane part F2 forward, and as the guide protrusions 343, 344 of the upper arm 342 move along the curved rails 312, 326, the moving path of the curved moving unit 340 may be set. The lower arm 341 may include a curved rack gear 341a in a rear direction thereof to receive power from the driving part 330.

The fixed part (fixed part) of fig. 5 may correspond to the fixed unit 310, and the moving part (moving part) may include the moving units 320, 340 and the display part 100 moving together with the moving units 320, 340.

The driving part 330 that provides power to the moving units 320, 340 may include a motor 331 and a pinion gear 334 that transmits power of the motor 331. The motor 331 may be fixed to the horizontal base 316. As shown in fig. 3, in order to transmit force to the moving units 320, 340 arranged in pairs in a bilateral symmetry manner, a horizontal shaft 333 may be included to transmit power of one motor 331 to the left and right.

In the case where two motors 331 are provided, the component cost increases, and in order to drive the pair of moving units 320, 340 synchronously, it is preferable to use one motor 331. As shown in fig. 4, the motor 331 is located between a pair of vertical bases 311, and a horizontal shaft 333 extends in the left-right direction and incorporates pinion gears 334 at end portions, respectively.

In order to disperse the force of the motor 331 to the pair of horizontal shafts 333 and change the rotation direction of the motor 331, a plurality of gears may be used, and a gear box 332 in which the gears are located may be located at a lower portion of the motor 331.

The pinion gear 334 may be engaged with a curved rack gear 341a formed at a lower arm 341 of the curved moving unit 340, and the curved rack gear 341a may draw a curve and move when the pinion gear 334 rotates. The rear surface of the lower arm 341, on which the curved rack gear 341a is formed, is projected in the rear direction so that a curved trajectory can be drawn instead of a straight line and moved when the pinion gear 334 rotates.

Fig. 6 is a rear perspective view showing a second state of the display device 10 of the embodiment of the present invention, and fig. 7 is a rear view of the second state of the display device 10 of the embodiment of the present invention.

If the driving part 330 is operated to switch from the first state to the second state, the curved moving unit 340 pushes the lower end of the display part 100 forward, and the upper plane part F1 of the display part 100 coupled with the straight moving unit 320 is moved in the vertical direction apart from the lower plane part F2, and is maintained in the forward direction.

The lower flat surface portion F2 of the display portion 100 may move further downward of the horizontal base 316 as shown in fig. 7, and may protrude forward as shown in fig. 6. The variable portion B may be curved, and a rear surface structure of the display portion located at a rear surface of the variable portion B may have a living hinge 365 to be bendable and deformable in an up-down direction.

The living hinge 365 may be formed by attaching each bar member in the form of a bar member extending in the horizontal direction aligned in the vertical direction, or may be formed by forming a groove 3652 extending in the horizontal direction in the back surface of the member having elasticity.

The upper and lower flat portions F1 and F2 are guided in combination with the moving units 320 and 340, but the shape of the variable portion B is changed, so it is difficult to provide brackets fastened to the moving units 320 and 340. The variable part B is not coupled to the moving units 320 and 340, but may be fastened to the side rail 313 guiding the moving path as shown in fig. 6, so as to move along the curved rails 312 and 326 along predetermined curved rails.

Fig. 8 is a diagram showing a rear structure of the display section 100 of the display device 10 according to the embodiment of the present invention. As described above, the display unit 100 of the present invention may be constituted by the upper flat surface portion F1, the variable portion B, and the lower flat surface portion F2, and the back plates 361 and 362 having rigidity may be coupled to the upper flat surface portion F1 and the lower flat surface portion F2.

The back plate may be divided into a first back plate 361 coupled to the upper side plane portion F1 and a second back plate 362 coupled to the lower side plane portion F2, a portion corresponding to the variable portion B may be omitted from a solid back plate to be bendable and deformable, and a movable hinge 365 may be provided.

The back plates 361, 362 may include extension portions 361a, 362a extending toward the variable portion B, and the extension portions 361a, 362a may not be coupled to the display portion 100, and thus may be spaced apart from the rear surface of the display portion 100 in the second state in which the variable portion B is bent (refer to fig. 15).

The end of the extension portion 361a of the first back plate 361 and the end of the extension portion 362a of the second back plate 362 may meet in the middle of the variable portion so as not to overlap.

If the motor 331 is driven in the first state, when the curved moving unit 340 moves forward downward, the upper end of the extension portion 362a of the second back plate 362 positioned at the lower portion is spaced apart from the rear surface of the display part 100, and then the lower end of the extension portion 361a of the first back plate 361 is spaced apart from the rear surface of the display part 100.

As the display part 100 moves to the lower side, the curved surface of the lower part of the variable part B becomes a plane again, and as shown in fig. 15, the interval between the second back plate 362 and the display panel 151 may become small.

The living hinge 365 may be covered by the extension portions 361a, 362a, and as shown in fig. 8, a hinge wing 368 for guiding a moving path of the variable portion B may protrude from a rear surface of the living hinge 365.

The hinge wing 368 may be constructed of a metallic material to be rigid, and in order to secure the hinge wing 368 to the living hinge 365, a wing securing portion 3681 covering the back of the living hinge 365 may be included.

Fig. 9 is a diagram showing the side rail 313 and hinge wing 368 of the display device 10 of the embodiment of the invention. (a) Is an enlarged view of the third guide projection 3683 inserted into the side rail 313, and (b) is a side view showing the second state.

As shown in fig. 9 (a), the hinge wing 368 may include a third guide protrusion 3683, which is inserted into the side rail 313 in such a manner that the third guide protrusion 3683 moves along the side rail 313 formed in a lateral direction perpendicular to the base 311.

As shown in fig. 9 (b), the upper side of the side rail 313 is straight in the vertical direction, but may include a curved line curved in the front direction at the lower side. In the first state, the third guide projection 3683 of the hinge wing 368 may be located at an upper straight section of the side rail 313, but may move toward a curved section of the side rail 313 when switching to the second state, and a lower portion of the display portion may be projected as shown in (b) of fig. 9.

As shown in fig. 8, the hinge wings 368 may be symmetrically disposed. At this time, the third guide protrusions 3683 may be disposed opposite to each other.

The hinge wings 368 are constructed of a rigid material, and thus the portions of the hinge wings 368 where the wing fixing portions 3681 are located may omit the extensions 361a, 362a, with only the extensions 361a, 362a being provided between the hinge wings 368.

Fig. 10 is an exploded perspective view of the display panel 151 and its rear structure of the display device 10 according to the embodiment of the present invention. The display part 100 may be composed of a display panel 151, a movable hinge 365 positioned at the rear surface of the display panel 151, and rear plates 361 and 362. The living hinge 365 may include: a front panel 367 for attaching to the display panel 151; and a non-elastic plate 366 covering the groove 3652 of the back surface of the living hinge 365 and setting a limit of changing curvature of the variable portion B.

As described above, the hinge wing portions 368 exposed outward may be located on the left and right of the rear surface of the living hinge 365, respectively. The portion overlapping the extensions 361a, 362a of the back plate may be covered by a non-elastic plate 366.

A panel substrate 182 controlling driving of the display panel 151 may be disposed at a lower portion of the display panel 151, and in order to connect the panel substrate 182 and the main substrate, as shown in fig. 8, the second back plate 362 may include an opening portion exposing a portion of the panel substrate.

Fig. 11 is a diagram illustrating a living hinge 365 of the display device 10 of an embodiment of the present invention. The living hinge 365 may be configured to be bendable by using a member 3651 of an elastic material, and may have a predetermined thickness so as to be capable of having rigidity to support the rear surface of the flexible display panel 151.

However, if the thickness of the living hinge 365 is thick, bending deformation is difficult, and thus the living hinge 365 may include the groove 3652 extending in the horizontal direction at the rear surface, so that bending deformation toward the front surface is easy. As shown in fig. 11, the groove 3652 may be cut in a V-shape.

The grooves 3652 are arranged side by side in the vertical direction, and the cross section between the grooves 3652 is in a trapezoid bar shape. For rigidity of the living hinge 365, a rigid rib 3653 may be interposed between the plurality of grooves 3652. The rigid ribs 3653 may comprise a metallic material. The rigid rib 3653 may be inserted into the elastic member 3651 of the living hinge 365 by forming a groove therein, or may be integrally formed with the elastic member 3651 by double injection molding.

The rigid ribs 3653 may have a length corresponding to the horizontal length of the display panel 151, but may be configured by arranging a plurality of rigid ribs 3653 cut to a predetermined length in the horizontal direction as shown in fig. 11 (b). At this time, if the ends of the rigid ribs 3653 are arranged to be offset from the rigid ribs 3653 adjacent in the vertical direction, the degree of freedom of the length variation in the vertical direction is increased, so that the bending deformation of the display panel 151 can be more smoothly performed.

Fig. 12 is a diagram illustrating a living hinge 365, a front panel 367, and a non-elastic panel 366 of a display device 10 of an embodiment of the present invention. (a) The first state is shown in which the variable portion B is planar, and the second state is shown in which the variable portion B is curved and bent.

The living hinge 365 has a prescribed thickness, and the radius of curvature of the front and back sides of the living hinge 365 are different. The front surface of the living hinge 365 is coupled with the display panel 151, and thus the length variation of the rear surface of the living hinge 365 is significantly greater than that of the front surface of the living hinge 365.

The front panel 367 may be combined with the display panel 151, may have adhesiveness, and may be hardly deformed or slightly expanded. Because of the large deformation of the living hinge 365, the length of the back-lying inelastic plate 366 should also vary widely.

Thus, a plate located on the back of the living hinge 365 may use a material having greater elasticity, but a non-elastic plate 366 of constant length may be used to limit the maximum bending deformation curvature.

As shown in fig. 12 (B), the length in the vertical direction of the inelastic plate 366 is determined in correspondence with the curvature of the second state, and is closely attached to the back surface of the movable hinge 365 in a state where the variable portion B is bent.

At this time, it may not be partially adhered to the grooves 3652, but only adhere to the strips (rigid ribs 3653) between the grooves 3652. As shown in (a), if converted to the first state, the width of the groove 3652 on the back side of the living hinge 365 is narrowed, and thus the portion of the inelastic plate 366 corresponding to the unbonded groove 3652 is bent, and may bulge in the back side direction (or enter between the grooves 3652) and form wrinkles.

When switching to the second state again, even if force is applied from the front face to deform the curvature of the variable portion B more greatly, the inelastic plate 366 does not elongate, so that the variable portion B can be supported without further bending.

Fig. 13 is a plan view showing the moving units 320, 340 of the display device 10 of the embodiment of the present invention. The vertical base 311 of the fixed unit 310, the moving plate 321 of the linear moving unit 320, the first front bracket 322, and the rear bracket 323 are shown. The curve moving unit 340 may include: a lower arm 341 having a curved rack gear 341a formed on the back surface thereof; and an upper arm 342 rotatably coupled to an upper side of the lower arm 341.

The curved moving unit 340 is located in a spaced-apart space between the moving plate 321 and the vertical base 311. Curved rails 312, 326 toward the upper arm 342 are formed at both the vertical base 311 and the moving plate 321, and the upper arm 342 of the curved moving unit 340 is coupled to both the vertical base 311 and the moving plate 321 by guide protrusions 343, 344 protruding at both sides thereof.

Fig. 14 is a sectional view A-A of fig. 4, and fig. 15 is a sectional view a '-a' of fig. 7. Fig. 14 and 15 are views from the outside of the moving plate 321. If the motor 331 is driven and the pinion 334 rotates, the curved rack gear 341a is pushed out toward the lower side forward so that the lower side planar portion F2 protrudes toward the lower side forward as shown in fig. 15.

The lower flat surface portion F2 moves downward, and therefore the variable portion B and the upper flat surface portion F1 are also pulled downward, and as shown in fig. 15, the linear movement unit 320 can also move downward.

Fig. 16 is a B-B cross-sectional view of fig. 4, and fig. 17 is a B '-B' cross-sectional view of fig. 7. Fig. 16 and 17 are views of the upper arm 342 viewed from the inside of the moving plate 321. The upper arm 342 and the first curved track 312 formed at the vertical base 311 are shown, and the first guide protrusion 343 formed at the upper arm 342 may be inserted into the first curved track 312 and moved. The first curved track 312 functions to guide the moving direction of the curved moving unit 340.

As shown in fig. 16 and 17, the first curved track 312 may be arranged in a pair in the front-rear direction, and the rear first curved track 312b located at the rear may be longer than the front first curved track 312a located at the front. This is because the curve moving unit 340 draws a curve and rotates, and thus the radius of rotation of the rear first guide protrusion 343b located at the end of the upper arm 342 is larger than that of the front first guide protrusion 343a, thereby moving a longer distance.

The angle of the upper arm 342 in fig. 17 is inclined further downward rearward than the angle of the upper arm 342 in fig. 16, and the positions of the lower ends of the pair of first curved rails 312 may be different from the positions of the upper ends.

If the curved moving unit 340 moves forward downward ((1)), the lower flat surface portion F2 moves downward ((2)), and the variable portion B and the upper flat surface portion F1 also move downward ((3)). The driving force of the upper plane portion F1 and the linear movement unit 320 is transmitted through the display portion 100 to apply a load to the display portion 100, and thus the display panel may be damaged. In addition, when the transition from the second state to the first state is made, the linear-motion unit 320 needs to be pushed up, and therefore, the transmission of the driving force of the motor 331 cannot be smoothly achieved as compared with the transition from the first state to the second state.

Thereby, a second curved track 326 may be formed at the moving plate 321, and a second guide protrusion 344 inserted into the second curved track 326 from the upper arm 342 may be further provided to transmit a driving force applied to the curved moving unit 340 to the straight moving unit 320 by directly fastening the curved moving unit 340 and the straight moving unit 320. The second guide protrusion 344 may be formed at an opposite side of the first guide protrusion 343.

Fig. 18 to 20 are diagrams showing the sliding actions of the linear movement unit 320 and the curved movement unit 340 of the display device 10 according to the embodiment of the present invention. Fig. 18 is a C-C sectional view of fig. 4, fig. 20 is a C '-C' sectional view of fig. 7, and fig. 19 is a sectional view showing the linear moving unit 320 and the curved moving unit 340 at intermediate positions of the first state and the second state.

The upper arm 342 connected to the upper side of the lower arm 341 is fastened by the moving plate 321, the second guide projection 344, and the second curved rail 326, which are the linear moving units 320, so that the upper arm 342 can transmit a force pulling the moving plate 321 downward.

However, since the curved moving unit 340 draws a curve and moves, and the linear moving unit 320 moves linearly in the up-down direction, the second curved path 326 may be designed such that the horizontal movement of the curved moving unit 340 performing the curved movement is offset by the second curved path 326 and the vertical force is transmitted to the moving plate 321.

As shown in fig. 18, a pair of second curved tracks 326 may be included, and a front second curved track 326a located at the front and a rear second curved track 326b may be included. The second guide protrusions 344 formed at the upper arm 342 may also include a front second guide protrusion 344a moving along the front second curved track 326a, and a rear second guide protrusion 344b moving along the rear second curved track 326b.

The curved moving unit 340 rotates and moves, and thus, as shown in fig. 18 and 20, the upper arm 342 is inclined at a different angle in the first state and the second state. In the second state, the curved moving unit 340 is inclined forward and protruded, and therefore, the upper arm 342 constituting the upper side of the curved moving unit 340 is inclined in the vertical direction more than in the first state.

Accordingly, the angle of the line B connecting the lower end of the front second curved track 326a and the lower end of the rear second curved track 326B is steeper than the angle of the line a connecting the upper end of the front second curved track 326a and the upper end of the rear second curved track 326B, corresponding to the angular change of the upper arm 342.

Both the linear moving unit 320 and the curved moving unit 340 move up and down, but the moving distances of the upper side and the lower side of the curved moving unit 340 are different. The lower side of the curved moving unit 340 moves a shorter distance in the vertical direction than the straight moving unit 320, but protrudes forward. The vertical direction moving distance of the upper side of the curved moving unit 340 may be greater than that of the straight moving unit 320.

This is because the curve moving unit 340 performs a vertical movement and a rotational movement with reference to a point of engagement with the pinion gear 334, and thus the vertical movement distances of the lower end and the upper end thereof are different.

Accordingly, the second curved path 326 reflects the difference in the movement trajectories of the linear moving unit 320 and the curved moving unit 340 to have a convex shape toward the rear. The first curved track 312 is formed at the vertical base 311 to have a longer length, but the second curved track 326 is formed at the moving plate 321 moving in the vertical direction to have a shorter length than the first curved track 312.

The peak points P1, P2 (or bending points) of the front second curved track 326a and the rear second curved track 326b protruding in the rear direction of the second curved track 326 are different. If the peak point P1 of the front second curved track 326a and the peak point P2 of the rear second curved track 326b are the same, it is difficult to shift the direction (shift to the front) when the second guide protrusion 344 reaches the peak points P1, P2.

In the case where the rear second guide protrusion 344b reaches the peak of the rear second curved track 326b, the front second curved track 326a is also during the downward movement, and thus, the rear second guide protrusion 344b may pass through the peak point P2 in the rear second curved track 326b and move along the rear second curved track 326b inclined forward.

As shown in fig. 19, in the case where the front second guide protrusion 344a reaches the peak point P1 of the front second curved track 326a, the upper arm 342 may move downward by the force of the rear second curved track 326b moving downward, and the front second guide protrusion 344a may continue to move downward along the front second curved track 326 a.

In addition, the curvature of the front second curved track 326a is greater than the curvature of the rear second curved track 326b, and the distance between the upper end and the lower end is short. That is, the radius of curvature of the rear second curved track 326b is greater than the radius of curvature of the front second curved track 326a, and the length of the rear second curved track 326b is longer than the length of the front second curved track 326 a. This is because the movement locus of the upper arm 342 is different from the portion and end portion where the lower arm 341 is joined.

When the second guide protrusion 344 reaches the lower end of the second curved track 326, the first guide protrusion 343 also reaches the lower end of the first curved track 312 and transitions to the second state. In the second state, the upper arm 342 may be disposed at a steeper angle than in the first state, and the lower arm 341 may be disposed so as to protrude forward, with the angle being inclined from the vertical direction.

In contrast, when the display part 100 moves upward in the opposite direction, the lower arm 341 moves upward and changes angle, and the upper arm 342 can move along the second curved track 326 and push the moving plate 321 upward, so that the upper part of the display part 100 moves upward.

As described above, the driving force of the curved moving unit 340 can be directly transmitted to the linear moving unit 320 through the second curved track 326 to guide the display part 100 to move upward, so that the movement can be more stably performed than the structure in which the force is transmitted to the linear moving unit 320 through the display part 100.

The present invention aims to provide a display device 10, which can be drawn in or out in a changeable position, can be drawn out when necessary, and can be stored when not necessary, thereby reducing the size of an exposed screen.

In addition, the shape of the display device 10 of the present invention can be changed, so that there is an advantage in that it can be drawn in or out even if the accommodation space of the instrument panel and the drawing direction are not uniform. The receiving space in the instrument panel may be formed to be recessed lower than the horizontal base of the fixing unit so that the display device 10 whose lower portion is protruded forward is smoothly received.

By the moving unit transmitting the force of the motor 331, the lower curved motion and the upper straight motion of the display part 100 can be simultaneously performed by the force of one motor 331.

The motor 331 may receive signals related to forward movement, reverse movement, parking, autonomous driving, etc. of the vehicle from the detection portion of the vehicle, and may maintain the display device 10 in the first state or the second state.

Specifically, when the vehicle is traveling forward, the second state may be switched so as not to obstruct the view of the driver, and the second state may be maintained in the parked state to prevent the display device 10 from being accidentally damaged. In autonomous driving, the first state may be maintained in order to provide other information such as navigation information to the rider including the driver, and in reverse driving, the first state may be maintained so that a rear image captured by a rear camera of the vehicle is displayed largely on the display device 10.

The first state or the second state may be automatically changed by the motor receiving the vehicle state-related signal from the detection portion, but may be manually changed by touching an input portion provided to the display device 10.

Even in a bent state, it has rigidity, so that touch input or the like can be realized, and durability can be ensured by preventing deformation in the opposite direction.

Fig. 21 to 22 show a flat or selectively bendable display device for a vehicle according to another embodiment of the present invention. In this embodiment, in order to connect the rear surface of the display assembly to the driving unit, i.e., the motor, a plurality of connection parts and at least one shaft are used. One of the connection portions is connected with the bendable portion of the display assembly, and the other of the connection portions is connected with the non-bendable portion of the display assembly. According to the action of the driving part, a link (link) connected to the curved portion of the display assembly has a relatively longer moving distance than another link connected to the non-curved portion of the display assembly. Therefore, as shown in fig. 4, the bendable portion is convexly bent rearward by the operation of the driving portion. The vertical movement range of the display assembly of this embodiment is much smaller than the embodiment of fig. 21 to 22. In particular, in fig. 1 to 20, the lower end portion of the display assembly does not substantially move in the vertical direction.

Fig. 23 is a block diagram for explaining a vehicle to which the display device of the present invention can be applied.

The vehicle 1000 may include a user interface device 200. The user interface device 200 may receive user input and provide information generated within the vehicle to the user.

The user interface device 200 may include an input 210, a built-in camera 220, a biometric detection 230, an output 250, and a processor 270.

The user interface device 200 may include a plurality of processors 270 or may not include a processor 270. On the other hand, the user interface device 200 may operate under the control of the control unit 170.

The display device of the present invention may operate in response to an input signal provided from the control unit 170 or at least one other device or unit in the vehicle, corresponding to the user interface device 200.

The vehicle may further include a detection portion 120 capable of detecting various states of the vehicle. The detection part 120 may include various types of sensors. The detection unit 120 may acquire detection signals regarding vehicle-related information such as attitude, collision, direction, position (GPS information), angle, speed, acceleration, inclination, forward and reverse, and the like.

Input signals indicating the state of the vehicle detected by the detection portion 120, such as movement, battery, fuel, tire, lamp, internal temperature, internal humidity, rotation angle of the steering wheel, external illumination, pressure applied to the accelerator pedal, pressure applied to the brake pedal, and the like, may be provided to the display device.

The vehicle may further include a control portion 170. The control unit 170 may control the vehicle driving device 600 that electrically controls operations of various devices in the vehicle, or may control the operation system 700 that controls various running modes of the vehicle.

Input signals representing states of the vehicle based on actions of various devices within the vehicle and/or various travel modes of the vehicle may also be provided to the display device.

The form of the display device of the present invention may be changed according to the received input signal.

As an example, in a case where the display device receives an input signal indicating that the vehicle is in use (for example, a case where a door of the vehicle is opened, a person sits on a driver's seat, or a case where an engine or a motor of the vehicle is running, or a case where the vehicle is moving), the display device may be curved, otherwise the display device may be flattened.

The display device changes its form according to the state of the vehicle, and therefore, the user can easily and intuitively understand the current state of the vehicle through the form of the display device. In addition, this curved configuration of the display device provides the advantage of not obstructing the driver's forward vision through the windshield.

In addition, a specific area within the screen of the curved display device can provide a driver with a convenient viewing angle, and thus, as long as the driver glances at the display device, the corresponding area can be effectively applied to transfer information about the current state of the vehicle.

As still another embodiment, the display device of the present invention may change its form according to an input signal representing a driving mode. For example, the display device may bend if it receives an input signal indicating that the vehicle is in manual mode, or otherwise (e.g., autonomous mode or auxiliary mode) the display device may flatten.

In the manual mode, the driver needs to look at the display device while closely observing the front through the windshield to quickly acquire the running information. The curved display device does not obstruct the view of the driver and a specific area of the curved display device can provide a more convenient viewing angle to the driver and thus may be more advantageous in the manual mode.

As a variant and vice versa. That is, if the display device receives an input signal prompting that the vehicle is in the manual mode, the display device may become flat, otherwise may bend. This variant also provides the advantage that the driver can quickly recognize and cope with a change from autonomous or auxiliary mode to manual mode based on the shape of the display device.

As a further embodiment, the display device of the present invention may change its form according to an input signal representing the state of the gearbox. For example, if the display device receives an input signal indicating that the gearbox is in the "driving" D state, the display device may bend, otherwise in the "reversing" R state the display device may flatten. Partial deformation is also possible. As an example, the display device may be curved when the gearbox is in the "park" P or "reverse" R state. Such an alternative embodiment provides the advantage that the driver can quickly and intuitively perceive the state of the gearbox without having to look at a screen or gear selector that provides information about the state of the gearbox.

The foregoing detailed description is not to be construed in all aspects as limiting, but rather as exemplary. The scope of the invention should be determined based on a fair interpretation of the accompanying claims, and all changes that come within the meaning and range of equivalency of the invention are intended to be embraced therein.
