Description

Variable display device {Variable display device}

The present invention relates to a variable display device capable of implementing various screen modes by three-dimensionally transforming the shape of a display portion.

Display technology has made significant progress from CRT to AMOLED technology, and recently, there has been a trend toward larger display devices by applying high-resolution OLED panels.

OLED is a technology that uses organic semiconductor materials to form a screen. Unlike LCD (Liquid Crystal Display), each pixel generates light on its own to form the screen, so there is no need for a backlight on the back of the display panel.

This allows OLEDs to be thinner, lighter, and more flexible than LCDs.

In particular, POLED is a variation of OLED display that can produce more flexible displays by using polymer materials.

Accordingly, various types of display devices, such as curved displays and foldable displays, are being released.

However, most display devices installed in existing vehicles are fixed screens, which not only makes the interior monotonous, but also makes it difficult to provide screens in various modes.

The matters described as background technology above are only intended to enhance understanding of the background of the present invention, and should not be taken as an acknowledgment that they correspond to prior art already known to those skilled in the art.

The present invention has been made to solve the problems described above, and provides a variable display device that can implement various screen modes by three-dimensionally transforming the shape of a display portion.

The present invention for achieving the above purpose may be characterized by including: a display unit for displaying an image; a pusher that moves in the X-axis direction while in contact with a portion of the rear surface of the display unit and selectively moves in the Y-axis direction to partially protrude the display unit in the X-axis direction.

A reinforcing member for reinforcing the rigidity of the display member is fixed to the rear of the display member; the reinforcing member can be arranged at a set interval along the Y-axis movement direction of the pusher.

The rear of the display portion is supported by the vehicle body; and as the display portion is protruded and moved by the pusher, the gap between the protruding rear of the display portion and the vehicle body can be blocked by the blocking means.

The above blocking means comprises a support area provided on a reinforcing member fixed to the rear of the display section, in which an end of the body is supported; a thickness area provided on a portion of the reinforcing member bordering the support area; and the thickness area is formed in a shape extending in the X-axis direction toward the body, so that a gap can be blocked by the thickness area.

A horizontal plane of a thickness region parallel to the X-axis direction can be formed in a shape that maintains constant surface contact with the body facing it.

The above blocking means is formed such that a moving part is fixed to the rear of the display part, the moving part moves together with the display part, and the moving part is formed in a shape that protrudes in the X-axis direction toward the vehicle body, so that the gap can be blocked by the moving part.

The horizontal plane of the moving part parallel to the X-axis can be formed in a shape that maintains constant surface contact with the body facing it.

An operating space is formed inside the above body; and within the operating space, a moving part is guided along the body and can move in the X-axis direction.

It may further include a first return means that provides elastic restoring force in the X-axis movement direction of the above moving part.

The above first return means may be a first return spring connected between the body and the moving part.

It may include an X-axis movement means for converting a rotational motion according to the driving force of the actuator into a linear motion to move the pusher in the X-axis direction; and a Y-axis movement means for converting a rotational motion according to the driving force of the actuator into a linear motion to move the pusher in the Y-axis direction.

The above X-axis moving means may include a first actuator providing a rotational driving force; a cam that is provided with the rotational driving force of the first actuator and rotates eccentrically around a camshaft orthogonal to the X-axis movement direction of the pusher, and has a cam profile on an outer surface that is supported on the rear of the pusher to move the pusher in the X-axis direction according to the eccentric rotation angle.

It may further include a second return means providing elastic restoring force with respect to the X-axis movement direction of the above pusher.

The second return means may include: a support plate arranged parallel to the pusher and guiding movement of the pusher in the X-axis direction; and a second return spring connected between the support plate and the pusher.

The above Y-axis moving means may include: a second actuator providing a rotational driving force; a support plate arranged parallel to the pusher and moved in the Y-axis direction together with the pusher; a screw nut fixed to the support plate; and a lead screw that penetrates the screw nut with a screw fastening structure and is rotated by the rotational driving force of the second actuator.

Through the above-described problem solving means, the present invention not only implements various screen modes by three-dimensionally transforming the shape of the display portion through the protruding operation of the display portion, but also has the effect of designing an interior in a newer and more unique way.

Moreover, it has the advantage of being able to provide various entertainment contents through the implementation of various screens, and also of configuring a user-friendly display environment as autonomous vehicles become activated.

A preferred embodiment of the present invention is described in detail with reference to the attached drawings as follows.

The variable display device of the present invention is configured to include a display unit (100) that displays an image; a pusher (300) that moves in the X-axis direction while in contact with a portion of the rear surface of the display unit (100) and selectively moves in the Y-axis direction to partially protrude the display unit (100) in the X-axis direction.

Referring to FIGS. 1 to 4, the display unit (100) is a very thin POLED display manufactured using a polymer material, and is flexible to deformation and bending.

The pusher (300) is installed on the rear of the display unit (100) and is formed with a left-right length shorter than the left-right length of the display unit (100), thereby overlapping a part of the display unit (100).

In particular, the pusher (300) can move in the X-axis direction, which is the forward/backward direction of the vehicle.

Accordingly, as shown in FIG. 3, by pushing the display unit (100) forward while the pusher (300) is in contact with the rear surface of the display unit (100), the display unit (100) pushed by the pusher (300) can protrude forward.

Additionally, the pusher (300) can move in the Y-axis direction, which is the left-right direction of the vehicle.

Accordingly, as shown in Fig. 4, the pusher (300) moves by pushing the display unit (100) located in the lateral direction from the position of the display unit (100) protruding forward, so that the display unit (100) pushed by the pusher (300) can protrude forward.

Of course, by being able to move the pusher (300) left and right in the state of Fig. 2, the position of the pusher (300) can be moved left and right, and after the pusher (300) is moved left and right, the pusher (300) can be moved forward to protrude the display unit (100).

In this way, the present invention not only implements various screen modes by changing the shape of the display unit (100) into three dimensions through the protruding operation of the display unit (100), but also enables designing interiors in a newer and more unique way.

In addition, it will be possible to provide various entertainment contents and also configure a user-friendly display environment as autonomous vehicles become activated.

In addition, the present invention provides that a reinforcing member (200) for reinforcing the rigidity of the display member (100) is fixed to the rear surface of the display member (100); and the reinforcing members (200) can be arranged at a predetermined interval along the Y-axis movement direction of the pusher (300).

Specifically, the reinforcing material (200) is for reinforcing the rigidity of the display unit (100) and can be attached to the rear surface of the display unit (100) using an adhesive (210) such as double-sided tape.

The above reinforcing material (200) is formed in a belt shape with a short width from left to right and a long length from top to bottom and is attached along the vertical length direction of the display unit (100).

In particular, the reinforcing material (200) is attached in multiple pieces at equal intervals along the left and right sides of the display unit (100) and is continuously and repeatedly attached.

Accordingly, the rear surface of the reinforcing material (200) is pushed by the pusher (300), so that the display part (100) can protrude.

Meanwhile, the present invention is characterized in that the rear surface of the display portion (100) is supported by the body (400); and as the display portion (100) is protruded and moved by the pusher (300), the gap (G) between the protruding rear surface of the display portion (100) and the body (400) can be blocked by a blocking means.

That is, when the display part (100) is protruded toward the passenger by the pusher (300), a gap (G) is formed between the protruding part of the display part (100) and the body (400) as shown in FIG. 7.

Accordingly, the present invention blocks moisture and foreign substances from flowing in through the gap (G) by blocking the above-mentioned gap (G) with a blocking means.

As a first embodiment of the above-mentioned blocking means, the gap (G) can be blocked by deforming the structure of the reinforcing material (200).

Specifically, the blocking means is provided with a support area (200a) in which an end of a body (400) is supported by a reinforcing member (200) fixed to the rear of the display unit (100); a thickness area (200b) is provided in a portion of the reinforcing member (200) bordering the support area (200a); and the thickness area (200b) is formed in a shape that extends in the X-axis direction toward the body (400), so that a gap (G) can be blocked by the thickness area (200b).

Referring to FIGS. 5 and 6, the rear middle portion of the reinforcing member (200) is supported by the front end of a body (400), such as a dashboard or instrument panel of a vehicle, and the rear portion of the reinforcing member (200) supported by the body (400) becomes a support area (200a).

And, the reinforcing material (200) connected to the lower end of the support area (200a) is expanded and formed in a shape that protrudes toward the body (400) to form a thickness area (200b).

That is, the front-back thickness of the thickness region (200b) is formed thicker than the front-back thickness of the support region (200a).

At this time, the pusher (300) can be configured to push the thickness area (200b).

However, the pusher (300) may be configured to push an area corresponding to the upper portion of the support area (200a), and the thickness area (200b) may also be formed at a portion connected to the upper portion of the support area (200a) rather than the lower portion of the support area (200a).

According to this configuration, when a part of the display unit (100) protrudes toward the passenger by the pusher (300) as shown in FIG. 6 and a gap (G) is generated between the display unit (100) and the body (400), the lower part of the gap (G) is blocked by the thickness area (200b) of the reinforcing material (200).

Therefore, foreign substances or moisture, etc. are prevented from entering through the gap (G).

In addition, the present invention can be formed in a shape in which a horizontal plane of a thickness region (200b) parallel to the X-axis direction maintains a constant surface contact state with a body (400) facing it.

Specifically, the front-back thickness of the above thickness region (200b) must be formed longer than the maximum front-back length of the gap (G) that is generated when the display unit (100) protrudes.

And, the horizontal plane at the top of the thickness region (200b) can be provided in a state in which it comes into contact with the horizontal plane at the bottom of the body (400).

Accordingly, even in a situation where the display unit (100) protrudes as in Fig. 6, the horizontal plane at the top of the thickness region (200b) and the horizontal plane at the bottom of the body (400) maintain surface contact with each other, thereby preventing foreign substances and moisture from entering through the gap (G).

Meanwhile, as a second embodiment of the above-mentioned blocking means, the gap (G) can be blocked by adding a configuration of a moving part (410).

Specifically, the blocking means is formed such that a moving part (410) is fixed to the rear of the display part (100) so that the moving part (410) moves together with the display part (100); and the moving part (410) is formed in a shape that protrudes in the X-axis direction toward the body (400), so that the gap (G) can be blocked by the moving part (410).

Referring to FIGS. 8 to 10, a moving part (410) is fixed to the rear middle portion of the reinforcing member (200) in a shape that protrudes toward the body (400), and the moving part (410) moves back and forth together with the display part (100).

And, the rear middle part of the reinforcement (200) is supported on the front end of the vehicle body (400), such as the dashboard or instrument panel of the vehicle.

At this time, the pusher (300) can be configured to push the reinforcing material (200) on the lower rear side of the display portion (100).

However, the pusher (300) may be configured to push the reinforcing material (200) portion at the upper rear of the display portion (100).

According to this configuration, when a part of the display unit (100) protrudes toward the passenger by the pusher (300) as shown in Fig. 10 and a gap (G) is generated between the display unit (100) and the body (400), the moving unit (410) blocks the gap (G) portion.

Therefore, foreign substances or moisture, etc. are prevented from entering through the gap (G).

In addition, the present invention can be formed in a shape in which the horizontal plane of the moving part (410) parallel to the X-axis direction maintains a constant surface contact state with the body (400) facing it.

In addition, an operating space is formed inside the body (400); within the operating space, a moving part (410) can be guided along the body (400) and moved in the X-axis direction.

Specifically, the front-back length of the moving part (410) must be formed longer than the maximum front-back length of the gap (G) generated by the protrusion of the display part (100).

In addition, the horizontal surface of the upper part of the moving part (410) may be provided in a state in which it comes into contact with the inner horizontal surface of the upper part of the operating space of the body (400).

Accordingly, even in a situation where the display unit (100) protrudes as in Fig. 10, the horizontal plane at the top of the moving unit (410) and the inner horizontal plane at the top of the operating space of the body (400) are in surface contact with each other, thereby preventing foreign substances and moisture from entering through the gap (G).

In addition, the present invention may further include a first return means that provides elastic restoring force in the X-axis movement direction of the moving part (410).

Specifically, the first return means may be a first return spring (420) of a coil spring structure connected between the body (400) and the moving part (410).

That is, one end of the first return spring (420) can be fixed to the inside of the operating space of the body (400), and the other end of the first return spring (420) can be fixed to the rear end of the moving part (410).

Accordingly, the moving part (410) moved toward the passenger together with the display part (100) can be restored and moved by the elastic restoring force of the first return spring (420).

Meanwhile, the present invention is configured to include an X-axis movement means that converts a rotational motion according to the driving force of an actuator into a linear motion to move a pusher (300) in the X-axis direction; and a Y-axis movement means that converts a rotational motion according to the driving force of an actuator into a linear motion to move a pusher (300) in the Y-axis direction.

First, the X-axis moving means is configured to include a first actuator (510) that provides a rotational driving force; a cam (530) that is eccentrically rotated around a cam shaft (531) that is orthogonal to the X-axis movement direction of the pusher (300) by providing the rotational driving force of the first actuator (510), and a cam profile on an outer surface of which is supported on the rear of the pusher (300) to move the pusher (300) in the X-axis direction according to the eccentric rotation angle.

Referring to FIGS. 11 to 14, a support plate (500) is provided parallel to the pusher (300) at the rear of the pusher (300).

The above first actuator (510) may be a motor, and the motor is mounted on the support plate (500) to provide rotational driving force.

And, a camshaft (531) is coupled to the support plate (500), and a cam (530) is provided to be able to rotate eccentrically around the camshaft (531).

A pulley is coupled to the camshaft (531), and at least one pulley is coupled between the first actuator (510) and the cam (530).

And, the above pulleys are connected by a belt (520), and the rotational force of the first actuator (510) is provided to one of the pulleys, so that the cam (530) can rotate around the camshaft (531) by belt drive.

In particular, since the cam profile on the outer surface of the cam (530) is in constant contact with the rear surface of the pusher (300) while being supported, the amount of movement of the pusher (300) is determined according to the shape of the cam profile and the angle at which the cam (530) rotates eccentrically when the cam (530) rotates eccentrically.

Accordingly, by controlling the protrusion amount of the display unit (100), various screen modes can be implemented based on the protrusion amount of the display unit (100).

In addition, the present invention may further include a second return means that provides elastic restoring force with respect to the X-axis movement direction of the pusher (300).

Specifically, the second return means is configured to include a support plate (500) arranged parallel to the pusher (300) and guiding the X-axis movement of the pusher (300); and a second return spring (550) of a coil spring structure connected between the support plate (500) and the pusher (300).

However, a pusher guide (540) having a shape that protrudes toward the support plate (500) on both sides of the pusher (300) may be fixed. In this case, a second return spring (550) may be connected to the pusher guide (540).

That is, one end of the second return spring (550) can be fixed to the support plate (500), and the other end of the second return spring (550) can be fixed to the side of the pusher guide (540).

Accordingly, the pusher (300) that pushes the display unit (100) can be restored and moved by the elastic restoring force of the second return spring (550).

Meanwhile, the Y-axis moving means is configured to include a second actuator (560) that provides a rotational driving force; a support plate (500) that is arranged parallel to the pusher (300) and moves in the Y-axis direction together with the pusher (300); a screw nut (580) fixed to the support plate (500); and a lead screw (570) that penetrates the screw nut (580) with a screw fastening structure and is rotated by the rotational driving force of the second actuator (560).

Referring to FIG. 15, the second actuator (560) may be a motor, and a lead screw (570) is coupled to the shaft of the motor to provide rotational driving force to the lead screw (570).

The above lead screw (570) is provided in the left and right longitudinal direction of the support plate (500), and a screw nut (580) is fixed to the lower sides of both sides of the support plate (500), and the lead screw (570) penetrates the screw nut (580) with a screw fastening structure, so that when the lead screw (570) rotates, the screw nut (580) moves along the lead screw (570), causing the support plate (500) to move left and right.

At this time, a linear guide (590) is provided in a shape that wraps around the longitudinal direction of the lead screw (570), and the linear guide (590) serves to guide the left-right linear movement of the support plate (500).

In this way, the present invention not only implements various screen modes by changing the shape of the display unit (100) into three dimensions through the protruding operation of the display unit (100), but also enables designing interiors in a newer and more unique way.

Moreover, through the implementation of various screens, it is possible to provide various entertainment contents and also configure a user-friendly display environment as autonomous vehicles are activated.

Meanwhile, although the present invention has been described in detail only with respect to the above-mentioned specific examples, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and it is natural that such modifications and variations fall within the scope of the appended claims.
