[0001] References to related applications

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2020-0083360, filed on Jul. 7, 2020, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to a display apparatus for a vehicle, and more particularly, to a display apparatus for a vehicle that is positioned flush with an interior portion of a vehicle and has a display unit that is folded or unfolded by a drive unit provided in the display apparatus. Background Art

[0004] Recently, as an outside rearview mirror of a vehicle, an electronic CMS (camera-based monitoring system) is commercially available, and the electronic CMS has an inherent function of showing an area behind the vehicle, and has a camera configured to capture an image of the area behind the vehicle, and a display device configured to display the image, thereby improving the performance of the vehicle and realizing a high-end design.

[0005] A limitation of the outside rearview mirror to which the electronic CMS is applied is that a structure for showing the external environment around the vehicle to the driver needs to be provided in the interior space of the vehicle, which reduces the degree of freedom in designing the interior of the vehicle.

[0006] Therefore, due to the small space in the vehicle, the outside rearview mirror in the related art to which the CMS is applied adopts a display with a small area. In addition, if the display is installed at a position where the display blocks the front window of the vehicle, it may block the driver's field of view.

[0007] The outside rearview mirror in the related art to which the CMS is applied is configured so that the display is installed in a space portion that is otherwise formed in the interior space of the vehicle, or is installed in the interior space whose shape has changed. As a result, there is a concern that unexpected problems may occur in the interior structure of the vehicle.

[0008] If the display is mounted on the outside of the vehicle, there is no great difference in function from the function of ensuring the rearward field of view of the visor-type outside rearview mirror in the related art, and as a result, the necessity of applying the CMS is reduced. Summary of the Invention

[0009] The present disclosure provides an outside mirror type display device for a vehicle, wherein a display unit is installed in an interior space of the vehicle to show an area behind the vehicle, the display device occupies a small interior space of the vehicle, the display device is kept at a position that is the same as that of a mirror type outside rearview mirror in the related art to the greatest extent possible, does not cause unnecessary rejection by the driver, and can be adjusted to provide an optimal viewing angle of the external environment around the vehicle by tilting the display unit according to the driver's viewing angle.

[0010] Exemplary embodiments of the present disclosure provide a side mirror type display apparatus for a vehicle, wherein the display apparatus is positioned flush with an interior portion of the vehicle, and a display unit is folded or unfolded by a driving unit provided in the display apparatus.

[0011] According to the exterior rearview mirror type display device for a vehicle according to the present disclosure configured as described above, the display device occupies a small interior space of the vehicle because it has a structure in which the display device is installed at the same position as that of a visor-type exterior rearview mirror in the related art and the display unit is variously arranged. As a result, it is possible to provide an exterior rearview mirror to which a CMS is applied without compromising the degree of freedom in designing the interior of the vehicle.

[0012] Since the display unit is configured to be tilted in the left-right direction, the rearward field of view required for driving the vehicle can be ensured to the greatest extent.

[0013] The display unit can display an image of an area in front of the vehicle and an image of an area beside the vehicle, so that various fields of view of the driver can be ensured, thereby contributing to safe driving. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] Hereinafter, the configuration and operation of the outside rearview mirror type display apparatus for a vehicle according to the present disclosure will be described in detail with reference to the accompanying drawings.

[0025] However, the disclosed drawings are provided as examples to fully convey the spirit of the present disclosure to those skilled in the art. Therefore, the present disclosure is not limited to the drawings disclosed below, and may be specified as other aspects.

[0026] Unless otherwise defined, the terms used in the description of the present disclosure have the meanings that are commonly understood by those of ordinary skill in the art to which the present disclosure belongs, and in the following description and drawings, detailed descriptions of well-known functions and configurations will be omitted to avoid unnecessarily obscuring the subject matter of the present disclosure.

[0027] Referring to related art, Korean Patent Publication No. 10-1998-3522 discloses a layout structure for a vehicle display in which a display panel can be extended and retracted upward, allowing the screen on the display to be easily viewed without obstructing the driver's field of vision while driving the vehicle. However, since the display panel can only be operated upward or downward, there are limitations in ensuring the driver's field of vision. As a result, there is a disadvantage in that a separate space must be provided to ensure the structure for installing the display inside the vehicle.

[0028] Korean Patent Application Publication No. 10-2019-1082 discloses a vehicle without side mirrors, which has a configuration of a side mirror provided with a reflector that reflects the rear appearance and displays images captured by left and right cameras in real time. However, there is a problem in that since two cameras are used, it is difficult to secure space for installing the cameras and the rearview mirror installed in the vehicle, and the manufacturing cost increases.

[0029] Japanese Patent Application Publication No. JP2010-116125 discloses a driving support device equipped with a rearview assist device. The device includes a moving mechanism that moves an electronic display system between the interior and exterior of a vehicle, thereby enabling rearview recognition in the event of a malfunction of the electronic display system. However, the need to provide storage space within the vehicle body for the device poses structural limitations when designing the vehicle interior.

[0030] Japanese Patent Application Publication No. JP2016-037109 discloses a rearview camera system designed to improve aerodynamics and identify the area behind the vehicle in the event of camera failure. However, the mirror portion protrudes outward, and the mirror is angled toward the driver's seat. As a result, there are concerns about light blinding due to light reflection, which could hinder safe driving. Furthermore, since the device is mounted on the side of the vehicle, there are concerns that the driver's forward and lateral vision may be obstructed.

[0031] U.S. Patent Application Publication No. US2019-161014 discloses an apparatus and method for controlling a vehicle's side-view mirror system. In this system, a side-view mirror camera system is fixed to the vehicle's exterior, and a reflective plate protrudes by moving between the vehicle's interior and exterior as needed, thereby ensuring an external field of view through the use of the reflector. However, the need for a separate mounting space within the vehicle's interior creates structural limitations when designing the vehicle's interior. Furthermore, there are concerns that the structure for mounting the auxiliary mirror on a portion of the exterior cover may violate regulations.

[0032] Figures 1A to 1C is a configuration diagram of a side rearview mirror type display device for a vehicle according to the present disclosure, wherein Figure 1A is a three-dimensional diagram of the display device, Figure 1B is a perspective view showing a state in which a display unit of a display device is disposed, and Figure 1C It is a view showing a state in which a display device is installed.

[0033] refer to Figure 1A , a side rearview mirror type display apparatus 1 for a vehicle according to the present disclosure includes: a display unit 20 configured to show an external environment around the vehicle; and a housing 10 configured to support the display unit 20 .

[0034] The display unit 20 of the display apparatus 1 according to the present disclosure employs a variable display member having a flexible panel. The variable display member is a well-known member currently employed in mobile communication devices such as smartphones.

[0035] Therefore, if Figure 1B As shown, in the display device according to the present disclosure, the display unit 20 having a variable display member is configured to be folded or unfolded. The operation of folding or unfolding the display unit 20 can be performed by the driving unit 100 embedded in the housing 10, and will be described below.

[0036] In the display apparatus 1 according to the present disclosure, when the vehicle starts, the display unit 20 may be unfolded and deployed.

[0037] like Figure 1C As shown, the display device 1 according to the present disclosure can be positioned flush with the interior portion of the vehicle. In particular, the display device 1 can be installed at the intersection of the front lower portion of the window frame 3 at the driver's seat and the auxiliary seat of the vehicle and the upper portion 2 of the door.

[0038] This position corresponds to the quarter glass trim of the front door, where conventional mirror-type outside rearview mirrors are typically attached to the exterior of window frame 3. Specifically, this position is as close as possible to the mounting location of conventional mirror-type outside rearview mirrors, thereby ensuring the same level of outside vision as conventional mirror-type outside rearview mirrors without causing unnecessary driver discomfort. Specifically, this position allows the display unit 20 to be easily tilted according to the driver's viewing angle.

[0039] Figure 2 is a perspective view showing the interior of a display device according to the present disclosure, Figure 3 is an exploded perspective view of a display device according to the present disclosure.

[0040] First, refer to Figure 2 In the display device 1 according to the present disclosure, a flexible display unit 20 is connected to the outside of the shell 10, the display unit 20 is mounted on the surface of an auxiliary mount 40 and the surface of a main mount 30, the auxiliary mount 40 is positioned on the front surface 12 of the shell 10, the main mount 30 is positioned on the side surface 15 of the shell 10, and the main mount 30 and the auxiliary mount 40 are moved by the operation of a driving unit 100 installed in a space portion 14 in the shell 10, so that the display unit 20 is unfolded or folded.

[0041] Housing 10 has a triangular box shape and includes a bottom surface 11, a front surface 12, a rear surface 13, and side surfaces 15 formed on the left and right sides of front surface 12. Rear surface 13 extends obliquely from the upper portion of front surface 12 toward bottom surface 11, allowing bottom surface 11 to be integrally mounted on a triangular window glass trim portion of a front door portion. A vacant space 14 is provided in housing 10, and a drive unit 100 configured to operate main mount 30 and auxiliary mount 40 is mounted in space 14.

[0042] The display unit 20 having an area capable of covering the front surface 12 and one side surface 15 of the housing 10 may be mounted on the housing 10 so as to be deployable or foldable.

[0043] In this case, the display unit 20 is mounted on the surface of the main mount 30 and the surface of the auxiliary mount 40, and the main mount 30 and the auxiliary mount 40 are connected to the housing 10 by a hinge that is inserted into two slits 16 formed at one edge of the front surface 12 of the housing 10.

[0044] refer to Figure 3The main mount 30 has a flat plate-shaped body 30a having a front surface 31 on which the display unit 20 is mounted and a rear surface 32 in contact with the side surface 15 of the housing 10. An upper hinge 33, a central hinge 35, and a lower hinge 34 are sequentially provided on the side surface of the body 30a in a direction from the upper side to the lower side of the side surface of the body 30a.

[0045] The auxiliary mount 40 has a main body 40a having a front surface to which a front cover 41 is attached and a rear surface to which a rear cover 42 is attached. Long holes 47 are formed in the upper and lower portions of the main body 40a, and springs 48 are inserted into the long holes 47.

[0046] A pusher 49 is provided on the front cover 41 and is inserted into the long hole 47 to push the spring 48 to one side. The rear cover 42 is attached to the main body 40a so as to shield the rear surface of the main body 40a.

[0047] On the side surface of the main body 40a of the auxiliary mount 40, the upper connecting hinge 43 and the central upper connecting hinge 45 are provided to be connected to the upper hinge 33 of the main mount 30, the central lower connecting hinge 35 is provided to be connected to the central hinge 35 of the main mount 30, and the lower connecting hinge 44 is provided to be connected to the lower hinge 34 of the main mount 30.

[0048] In this case, the main mount 30 and the auxiliary mount 40 are folded or unfolded relative to the hinge connection portion to perform an operation of unfolding (deploying) and folding the display unit 20 mounted on the surface of the main mount 30 and the surface of the auxiliary mount 40. To perform this operation, a driving unit 100 configured to operate the main mount 30 and the auxiliary mount 40 is installed in the space portion 14 inside the housing 10.

[0049] Figures 4A to 4C is a detailed view of a driving unit of a display device according to the present disclosure, wherein Figure 4A This is a three-dimensional diagram of the drive unit. Figure 4B is a view showing a state in which the first motor of the drive unit operates, and Figure 4C is a view showing a state in which the second motor of the driving unit operates.

[0050] First, refer to Figure 4A The drive unit 100 includes a first motor 110 and a second motor 120, the first motor 110 is configured to provide power for moving the auxiliary mount 40 forward or backward, and the second motor 120 is configured to provide power for moving the main mount 30 forward or backward.

[0051] The drive unit 100 includes: a first driving gear 111 connected to the shaft of the first motor 110; a pair of first driven gears 112 and 113 that are meshed with the first driving gear 111 and are configured to transmit rotational force; and an upper driven gear 60 that is inserted between the central upper connecting hinge 45 and the central lower connecting hinge 46 of the auxiliary mounting base 40 and is meshed with the first driven gear 113 at the rear end.

[0052] In this case, the upper driven gear 60 rotates about the shaft 50 by the rotational force transmitted from the first driven gears 112 and 113 and rotates both the central upper coupling hinge 45 and the central lower coupling hinge 46 passed by the shaft 50, thereby moving the auxiliary mount 40 forward or backward.

[0053] Specifically, if Figure 4B As shown, Figure 4B Shown Figure 4A In the top plan view of portion A in FIG, when the first driving gear 111 of the first motor 110 rotates clockwise, rotational force is transmitted, causing the upper driven gear 60 to rotate counterclockwise and the auxiliary mount 40 to move forward (in the direction indicated by 1). When the first driving gear 111 of the first motor 110 rotates counterclockwise, rotational force is transmitted, causing the upper driven gear 60 to rotate clockwise and the auxiliary mount 40 to move backward (in the direction indicated by 2).

[0054] At the same time, in order to reliably transmit the rotational force from the upper driven gear 60, a gear train (not shown) meshing with the upper driven gear 60 can be set on the side wall of the auxiliary mounting base 40 between the central upper connecting hinge 45 and the central lower connecting hinge 46 of the auxiliary mounting base 40.

[0055] The drive unit 100 includes: a second driving gear 121 connected to the shaft of the second motor 120; a pair of second driven gears 122 and 123 that are meshed with the second driving gear 121 and are configured to transmit rotational force; and a lower driven gear 70 that is inserted between the central hinge 35 and the lower hinge 36 of the main mount 30 and meshed with the second driven gear 123 at the rear end.

[0056] In this case, the lower driven gear 70 rotates about the shaft 50 by the rotational force transmitted from the second driven gears 122 and 123 and rotates both the central hinge 35 and the lower hinge 34 passed through by the shaft 50 , thereby moving the main mount 30 forward or backward.

[0057] Specifically, if Figure 4C As shown, Figure 4C Shown Figure 4AIn the top plan view of portion B in FIG, when the second driving gear 121 of the second motor 120 rotates clockwise, rotational force is transmitted, causing the lower driven gear 70 to rotate counterclockwise and the main mount 30 to move forward (in the direction indicated by 1). When the second driving gear 121 of the second motor 120 rotates counterclockwise, rotational force is transmitted, causing the lower driven gear 70 to rotate clockwise and the main mount 30 to move backward (in the direction indicated by 2).

[0058] Meanwhile, in order to reliably transmit the rotational force from the lower driven gear 70 , a gear train (not shown) meshing with the lower driven gear 70 may be provided on a side wall of the main mount 30 between the central hinge 35 and the lower hinge 34 of the main mount 30 .

[0059] Figures 5A to 5C is an operational state diagram illustrating a process in which a display unit of a display device according to the present disclosure is deployed. Figures 5A to 5C It is shown that the above reference Figure 4B and Figure 4C The state where the main mount 30 and the auxiliary mount 40 are unfolded and deployed is described by rotating the first motor 110 and the second motor 120 of the driving unit 100 .

[0060] That is, when the vehicle is in the left state ( Figure 5A ) is started in a state where the main mount 30 and the auxiliary mount 40 are folded on the front surface 12 and the side surface 15 of the housing 10, the first motor 110 and the second motor 120 are rotated by automatic control or manual manipulation of the driver, so that the first driving gear 111 and the second driving gear 121 rotate clockwise, and the main mount 30 and the auxiliary mount 40 are deployed forward, as in the center state ( Figure 5B ) as indicated below.

[0061] Next, when the first motor 110 and the second motor 120 are continuously operated, and as in the right state ( Figure 5C ), when a flat state in which the angle between the main mount 30 and the auxiliary mount 40 is 180 degrees is formed, the operation of the motors 110 and 120 is stopped, and the display unit 20 mounted on the main mount 30 and the auxiliary mount 40 is maintained in the expanded state so that the environment outside the vehicle is displayed in this state.

[0062] As described above, the display apparatus 1 according to the present disclosure may perform a tilting operation of adjusting the angle of the display unit 20 in a state in which the display unit 20 is fully unfolded.

[0063] Figure 6A 、 Figure 6B 、 Figure 7A and Figure 7Bis an operational state diagram showing a state in which the display unit of the display device according to the present disclosure is tilted, wherein Figure 6A is a view showing a state in which the display unit is tilted to the left, Figure 6B is a view showing a state in which the drive unit is operated by tilting leftward, Figure 7A is a view showing a state in which the drive unit is tilted to the right, and Figure 7B It is a view showing a state in which the driving unit is operated by tilting to the right.

[0064] First, refer to Figure 6A and Figure 6B , in order to make the fully unfolded display unit 20 as Figure 6A As indicated, to tilt in the left direction, the first motor 110 rotates clockwise to rotate the auxiliary mount 40 forward, and the second motor 120 rotates counterclockwise to rotate the main mount 30 backward, so that the auxiliary mount 40 and the main mount 30 rotate to the left at the same time, and the display unit 20 mounted on the auxiliary mount 40 and the main mount 30 also tilts to the left along the auxiliary mount 40 and the main mount 30.

[0065] refer to Figure 7A and Figure 7B , in order to make the fully unfolded display unit 20 as Figure 7A As indicated, the display unit 20 mounted on the auxiliary mount 40 and the main mount 30 is tilted to the right along the auxiliary mount 40 and the main mount 30.

[0066] When the display unit 20 is fully deployed as the auxiliary mounting seat 40 and the main mounting seat 30 are unfolded, the display unit 20 of the display device 1 according to the present disclosure performs an operation of pushing the front cover 41 of the auxiliary mounting seat 40 outward to prevent the boundary portion between a portion of the display unit 20 mounted on the auxiliary mounting seat 40 and a portion of the display unit 20 mounted on the main mounting seat 30 from wrinkling.

[0067] Figure 8A and Figure 8B 1 is a perspective view showing a state in which a spring operates when the display unit of the display device according to the present disclosure is folded and deployed. Figure 8A and Figure 8B As shown, when the display unit 20 is folded as indicated in the left portion ( Figure 8A), the front cover 41 of the auxiliary mount 40 receives a force in the direction toward the main mount 30, so that the pusher 49 inserted into the long hole 47 compresses the spring 48. However, when the display unit 20 is deployed as indicated in the right portion ( Figure 8B ), the display unit 40 is unfolded, and the front cover 41 of the auxiliary mount 40 moves in a direction opposite to the direction toward the main mount 30, so that the spring 49 compressed by the pusher 49 inserted into the long hole 47 extends together with the movement of the front cover 41, applies tension to the pusher 49 inserted into the long hole 47, and tensioningly unfolds the display unit 20 mounted on the front cover 41 of the auxiliary mount 40. As a result, wrinkles in the boundary portion between the portion of the display unit 20 mounted on the auxiliary mount 40 and the portion of the display unit 20 mounted on the main mount 30 can be minimized.

[0068] Figure 9 An example is shown in which the display device 1 is applied to show the area behind the vehicle. When the vehicle starts, when the main mount 30 and the auxiliary mount 40 move forward by the operation of the first motor 110 and the second motor 120 of the drive unit 100, the display unit 20 folded in the housing 10 of the display device 1 according to the present disclosure is unfolded and deployed from the housing 10, wherein the display device is mounted on each of the two decorative triangular window glass decorative parts of the front door part in the interior space of the vehicle. At the same time, the auxiliary mount 40 is moved by the tension of the spring 48, and thus the display unit 20 is tensionedly unfolded. In this state, the display unit 20 tilts to the left or right to ensure the viewing angle required by the driver. Thereafter, the electronic control unit (ECU) of the vehicle displays the data of the rear image generated by the rear camera 200 installed on the vehicle on the display unit 20, thereby providing the driver with a rear view.

[0069] At the same time, the display device 1 according to the present disclosure uses different colors to display different vehicles on the display unit 20 according to the distance between the vehicles, allowing the driver to intuitively identify the perspective view of the vehicle approaching from the rear. For example, when the distance between a vehicle equipped with the display device according to the present disclosure and another vehicle is 0m to 5m, the boundary between the corresponding vehicles may be colored red. When the distance between the vehicles is 5m to 10m, the boundary between the corresponding vehicles may be colored blue.

[0070] The display device 1 according to the present disclosure can display a front image and a side image of a vehicle as well as a rear image of the vehicle. Figure 10 As shown, Figure 10An example is shown in which the display device is applied to display a front or side image of a vehicle. When a signal for instructing an electronic control unit (ECU) of the vehicle to display both the front and side images is input, the electronic control unit (ECU) of the vehicle can display image data of the front and side images generated by the front camera 210 and the side camera 220 installed on the vehicle on the folded display unit 20 or the deployed display unit 20, as shown in FIG. Figure 10 As shown, this provides the driver with forward and side views.

[0071] Figure 11 and Figure 12 is a flowchart of a method for controlling a display device according to the present disclosure, wherein Figure 11 is a flowchart of a control method when a display unit of a display device is deployed, and Figure 12 is a flowchart of a control method when a display unit of a display device is tilted.

[0072] First, refer to Figure 11 A control method when the display unit 20 according to the present disclosure is deployed is described. The electronic control unit (ECU) of the vehicle determines whether the key of the vehicle is turned on (for example, whether the key of the vehicle is inserted into the key box and positioned in the key-on position, or whether the electronic control unit (ECU) recognizes the smart key of the vehicle (S1), and the electronic control unit (ECU) determines whether the vehicle is started in the key-on state (start-on) (S2).

[0073] Next, when the vehicle starts, the electronic control unit (ECU) operates the driving unit 100 of the display apparatus 1 to unfold and deploy the display unit 20 ( S3 ), and displays a rear image of the vehicle generated by the rear camera 210 on the display unit 20 ( S4 ).

[0074] The electronic control unit (ECU) monitors the vehicle's status (S5). When the vehicle is turned off, the ECU operates the drive unit 100 of the display device 1 to fold the deployed display unit 20 (S6). Thereafter, the rear image is displayed for a predetermined time (in the exemplary embodiment of the present disclosure, the display of the rear image is maintained for approximately 30 seconds) (S7), and then the display of the rear image on the display unit 20 stops (S8).

[0075] When the window of the vehicle's front door is detected to be open during the monitoring in step S5 (S9), the electronic control unit (ECU) operates the drive unit 100 to fold the display unit 20 (S10). The electronic control unit (ECU) determines whether an input signal requesting the display of the front and side images of the vehicle has been input (e.g., a front and side display input switch mounted on the vehicle's console or door frame) (S11). When an input signal requesting the display of the front and side images has been input, the electronic control unit (ECU) displays the front and side images generated by the front camera 210 and the side camera 220 on the folded display unit 20 (S12), and the process returns to the vehicle monitoring step (S5).

[0076] However, in step S9, if the window of the vehicle front door is not detected to be open (S9), the electronic control unit (ECU) determines in step S11 whether an input signal requesting the display of the front and side images of the vehicle (for example, a front and side display input switch mounted on the console or door frame of the vehicle) is input (S11). When the input signal requesting the display of the front and side images is input, the electronic control unit (ECU) displays the front and side images generated by the front camera 210 and the side camera 220 on the deployed display unit 20 (S12), and the process returns to the vehicle monitoring step (S5).

[0077] Next, we will refer to Figure 12 The control method for tilting the display unit 20 according to the present disclosure is described. The electronic control unit (ECU) of the vehicle determines whether the display unit 20 is tilted in automatic mode or manual mode (S20). In the case of automatic mode, the electronic control unit (ECU) reads setting information about the tilt angle predetermined by the driver and stored in a memory (not shown) (S21), operates the drive unit 100 to deploy and unfold the display unit 20 (S22), and then operates the drive unit 100 to adjust the tilt angle of the display unit 20 to an angle consistent with the read setting information (S23).

[0078] In contrast, in step S20, when the display unit 20 is tilted in manual mode, the electronic control unit (ECU) receives an angle adjustment input signal (S24) from the outside rearview mirror angle adjustment switch 300 mounted on the vehicle door frame as shown in the figure, and operates the drive unit 100 to adjust the tilt angle of the display unit 20 based on the input signal (S25).
