Description

Technical Field

[0001] This disclosure relates to a display device for use in vehicles. Background Technology

[0002] Display devices used in vehicles provide content that matches the driving conditions.

[0003] Recently, with the advancement of autonomous driving technology, the development of infotainment functions in vehicles has become active. Therefore, large display devices should be driven separately to ensure a clear field of view.

[0004] One way to do this is to use a method of selectively exposing the display device, but this is disadvantageous because it makes it impossible to check road guidance and basic information while driving with the display device hidden.

[0005] In particular, when the display device is hidden to ensure the driver's clear view, the operation of infotainment functions may be restricted, which may actually distract the driver from driving. Summary of the Invention

[0006] To address the aforementioned issues, this disclosure aims to provide a display device for vehicles that can selectively control the exposure of the display area of ​​a screen unit to ensure convenience and safety.

[0007] The aspects of this disclosure are not limited thereto, and other aspects not described herein will be apparent to those skilled in the art from the following description.

[0008] A display device for a vehicle according to an embodiment of the present disclosure includes: a screen unit configured to output vehicle operation information and images of each function; and a drive unit configured to adjust the position of the screen unit by a rotary pop-up.

[0009] By adjusting the position of the screen unit through the driving unit, the exposure range of the display area can be selectively adjusted, and a predetermined image can be output according to the exposure range of the display area.

[0010] The drive unit may include an actuator, a rotating shaft configured to rotate and connected to the actuator, a first pinion gear connected to one end of the rotating shaft to rotate in connection with the rotating shaft, a first rack forming an upwardly inclined arch shape in the cockpit module of the vehicle and engaging with the first pinion gear, a second pinion gear connected to the other end of the rotating shaft to rotate in connection with the rotating shaft, and a second rack engaging with the second pinion gear, the second rack being symmetrical to the first rack and spaced apart from the first rack.

[0011] The drive unit may also include a cover, which includes a rotating shaft and a first pinion and a second pinion connected to the screen unit.

[0018] In this case, when a load is applied to the drive motor due to an external force during the adjustment of the position of the screen unit, the drive unit can control the drive motor's drive based on the current measured based on the load.

[0019] The screen unit may include hooks on its front and rear sides to engage with the cockpit module latches in a specific mode to ensure rigidity.

[0020] In off mode, the screen unit can output images containing only relatively simple information related to vehicle speed, direction of travel, and sound source.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concepts of this disclosure to those skilled in the art, and the scope of this disclosure should be defined by the claims. The terminology used herein is for the purpose of describing embodiments only and is not intended to limit this disclosure. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise. As used herein, the terms “comprising” or “including” specify the presence of the said components, steps, operations, and / or elements, but do not exclude the presence or addition of one or more other components, steps, operations, and / or elements. As used herein, the term “and / or” includes any and all combinations of one or more of the listed items.

[0040] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0041] Coordinate system display

[0042] In the accompanying drawings of this disclosure, the X-axis, Y-axis, and Z-axis represent a three-dimensional (3D) orthogonal coordinate system, which displays the coordinates of a point or vector relative to linear coordinate axes that intersect each other perpendicularly. For ease of description, in the 3D orthogonal coordinate system, the X-axis can be described as the axis facing the side of the vehicle in the width direction, the Y-axis can be described as the axis facing the side of the vehicle in the longitudinal direction, and the Z-axis can be described as the axis facing the top and bottom (top panel and bottom panel) of the vehicle.

[0043] Each of the X-axis, Y-axis, and Z-axis directions includes both positive and negative directions.

[0044] The positive X-axis direction is towards the right horizontally, while the negative X-axis direction is towards the left horizontally.

[0045] The positive Y-axis direction is the direction towards the front of the vehicle in the longitudinal direction, while the negative Y-axis direction is the direction towards the rear of the vehicle in the longitudinal direction.

[0046] The positive Z-axis direction is towards the roof of the vehicle, and the negative Z-axis direction is towards the bottom of the vehicle.

[0047] For ease of description, the positive and negative directions of each axis can be described based on the same or different reference points.

[0048] For example, in this disclosure, the positive X-axis direction and the negative X-axis direction are directions toward the right and left, respectively, but these directions can be determined relative to a reference point that may vary depending on the system.

[0049] First Implementation Method (Basic Structure)

[0050] Figure 1 This is a schematic front view of a display device for a vehicle according to a first embodiment of the present disclosure.

[0051] Reference Figure 1 The display device 1000 for a vehicle according to the first embodiment of the present disclosure includes a screen unit 1100, a driving unit 1200 and a control unit 1300.

[0052] Screen unit 1100 outputs vehicle operation information and images of each function. Screen unit 1100 is a large-screen display whose basic size and performance exceed those of existing displays (not shown) that only provide vehicle operation information.

[0053] In other words, when using autonomous mode, which has become widely used due to technological advancements, the screen unit 1100 can provide occupants with more comfortable and convenient information (e.g., entertainment information) in the form of images.

[0054] However, when the occupant does not use autonomous driving and must drive the vehicle himself, the large screen of the screen unit 1100 may obstruct the occupant's view, thus increasing the risk of a safety accident.

[0055] Therefore, the screen unit 1100 of this disclosure can provide the convenience of a large screen in autonomous driving mode (on mode), and control the degree of screen exposure in driving mode (off mode) to ensure the driver's field of vision.

[0056] Therefore, the position of the screen unit 1100 is adjusted by the driving unit 1200 to selectively control the exposure range of the display area, and a predetermined image can be output according to the exposure range of the display area.

[0057] The drive unit 1200 adjusts the position of the screen unit 1100 by rotating and popping it out.

[0058] The control unit 1300 can control the drive unit 1200 via predetermined commands or by operating a switch. The control unit 1300 may have control logic limited to the corresponding function, or it may be an electronic control unit (ECU) of the vehicle.

[0059] First implementation method (operating mechanism)

[0060] Figures 2 to 11 The components of a display device for a vehicle according to a first embodiment of the present disclosure and the relationship between the operation of the components are shown.

[0061] Reference Figure 2 and Figure 3 The position of the screen unit 1100 above the second rack 1270 can be adjusted by the drive unit 1200. Here, when the screen unit 1100 is in... Figure 1 The first rack 1250 and Figure 2 and Figure 3 When the second rack 1270 moves in the positive Y-axis direction, the screen unit 1100 can enter the open mode.

[0062] Conversely, when screen unit 1100 is in Figure 1 The first rack 1250 and Figure 2 and Figure 3 When the second rack 1270 moves in the negative Y-axis direction, the screen unit 1100 can enter the off mode.

[0063] Reference Figure 4As a basic function, the drive unit 1200 transmits driving force to the rotating shaft 1230 through the actuator 1210, so that the first pinion 1240 connected to one end of the rotating shaft 1230 engages with the first rack 1250 and rotates in connection with the rotating shaft 1230.

[0064] Therefore, the rotating shaft 1230 rotates in the direction of transmitting driving force from the actuator 1210, thereby causing the first pinion 1240, which rotates in connection with the rotating shaft 1230, to move while engaging with the first rack 1250.

[0065] When the first pinion 1240 rotates in the positive Y-axis direction, it is connected to Figures 1 to 3 The cover 1220 of the screen unit 1100 moves along the path of the first rack 1250 in the positive Y-axis direction.

[0066] Reference Figure 5 and Figure 6 The actuator 1210 includes a housing 1211, a drive motor 1212, a helical gear 1214, a spur gear 1215, an on switch 1216, and an off switch 1217.

[0067] The housing 1211 is located above the rotation axis 1230 and is also connected to the rear surface of the screen unit 1100.

[0068] The drive motor 1212 is located in the housing 1211 and has a drive shaft 1213.

[0069] The helical gear 1214 is connected to the drive shaft 1213 to rotate in connection with the drive shaft 1213.

[0070] The spur gear 1215 includes a first sawtooth 1215a that rotates in connection with the helical gear 1214, and a second sawtooth 1215b that rotates in connection with the first sawtooth 1215a and is connected to the rotating shaft 1230.

[0071] The switch 1216 is located on the upper end of the housing 1211 and detects the open position of the screen unit 1100.

[0072] The off switch 1217 is located at the lower end of the housing 1211 and detects the off position of the screen unit 1100.

[0073] The actuator 1210 can detect the current position of the screen unit 1100 by means of a magnet 1218 connected to the second sawtooth 1215b and a magnet sensor 1219 located in the area of ​​the housing 1211 and detecting the number of rotations of the magnet 1218.

[0074] As another example, such as Figure 7As shown, actuator 1210' may include an open switch 1216, an open switch 1217, a magnet 1218, and a magnet sensor 1219 to induce stable drive.

[0075] When a user initiates a reset via a separate switch (not shown) and / or a predetermined command, the drive unit 1200 moves the screen unit 1100 in the direction of either the off mode or the on mode.

[0076] Therefore, turning on switch 1216, turning off switch 1217, magnet 1218 and magnet sensor 1219 can detect the current reset position of screen unit 1100.

[0077] exist Figure 8 In the middle, the screen unit 1100 is in the off mode, so it outputs an image with only relatively simple information related to vehicle speed, operating direction and sound source.

[0078] On the other hand, Figure 9 In the middle, the screen unit 1100 is in the open mode, so it outputs a combination of vehicle operation information and entertainment information through multiple graphical user interfaces (GUIs).

[0079] exist Figure 10 and Figure 11 In the display device 1000' for vehicles, there are first hooks 1110 and second hooks 1120 to ensure rigidity.

[0080] The first hook 1110 and the second hook 1120 can be respectively located on the front and rear sides of the screen unit 1100, and when the screen unit 1100 is switched to the open mode, they are fastened together with the cockpit module 10.

[0081] For example, the first hook 1110 can be fixed to the lower fixed end 12 of the cockpit module 10, and the second hook 1120 can be fixed to the upper fixed end 11 of the cockpit module 10.

[0082] Second implementation method (basic structure and operating mechanism)

[0085] The screen unit 2100 outputs the corresponding image based on the closed mode where some areas of the screen unit 2100 are exposed on the cockpit module 10 or the open mode where all areas of the screen unit 2100 are exposed on the cockpit module 10.

[0086] In this case, the position of the screen unit 1100 is adjusted by the driving unit 2200 to selectively control the exposure range of the display area, and a predetermined image can be output according to the exposure range of the display area.

[0087] The drive unit 2200 can adjust the position of the screen unit 2100 according to the mode, and rotate it in the cockpit module 10 according to predetermined logic.

[0088] The drive unit 2200 includes an actuator 2210, a connecting rod 2220, and a hinge shaft 2230.

[0089] Actuator 2210 has a drive shaft (not shown).

[0090] Link 2220 connects the drive shaft and the screen unit 2100.

[0091] Hinge shaft 2230 connects the drive shaft of actuator 2210 and link 2220.

[0092] The hinge axis 2230 can be fixed at a predetermined angle to adjust the position of the screen unit 2100.

[0093] The screen unit 2100 may also include a first hook 2110 and a second hook 2120 on its front and rear sides to engage with the cockpit module 10 in the open mode for fastening, thereby ensuring rigidity.

[0094] According to this disclosure, the display device for vehicles can selectively control the exposure of the display area of ​​the screen unit, thereby ensuring convenience and safety.

[0095] In particular, according to this disclosure, different operational and entertainment information can be provided based on the degree of exposure of the display area of ​​the screen unit.

[0096] Furthermore, according to this disclosure, when shaking occurs due to external forces, durability can be maintained by using a reinforcing structure of the hook.

[0097] This disclosure is not limited to the above-described embodiments, and can be implemented in various forms within the permissible scope of the technical concept of this disclosure.
