[0038] In some embodiments, this application provides a display device 100 that can be used in a vehicle. The embodiments of this application do not specifically limit the type of vehicle; for example, the display device 100 provided in this application can be used in fuel-powered vehicles, electric vehicles, hybrid vehicles, or solar-powered vehicles. Furthermore, the display device 100 provided in this application can also be used in different types of vehicles. For example, the vehicle provided in this application can be a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV).

[0039] The display device 100 provides the driver with various information display and control functions required for operating the vehicle and is also an important part of the vehicle's interior design. For example, the display device 100 can integrate basic information displays such as a speedometer, tachometer, fuel gauge, and thermometer, and can also display advanced information such as navigation information, entertainment system status, multimedia information, and vehicle health status. For example, the display device 100 can also integrate function buttons for vehicle air conditioning adjustment, audio control, and lighting control. Furthermore, functions such as seat heating / ventilation and driving mode selection can also be integrated into the display device 100.

[0040] Next, we will refer to Figures 1-4 The present application will describe some embodiments of the display device 100.

[0041] See Figures 1-4 In some embodiments, this application provides a display device 100 that can be used in a vehicle. The display device 100 includes a decorative housing 1 and a display component 2 rotatably disposed within the decorative housing 1. The display component 2 is rotatable relative to the decorative housing 1 to switch between a first display position and a second display position. The rotation axis of the display component 2 extends vertically, which is consistent with the height direction of the vehicle. This means that during the rotation of the display component 2, it primarily occupies space in the width direction of the vehicle, thereby reducing the requirements for the length direction of the vehicle. Furthermore, the ability of the display component 2 to switch between the first and second display positions allows it to meet more diverse user needs.

[0042] Display component 2 includes at least two displays 21, which are arranged side by side on the front side of the rotation axis.

[0043] It should be noted that the front side of the rotation axis refers to the side of the rotation axis facing the passenger compartment of the vehicle.

[0044] The display component 2 includes at least two displays 21, which may include the following situations: for example, the display component 2 includes two displays 21; or for example, the display component 2 includes more than two displays 21, such as three or four displays 21.

[0045] The display screen 21 can be an organic light-emitting diode (OLED) screen, a micro organic light-emitting diode (MOLED) screen, a quantum dot light-emitting diode (QLED) screen, a liquid crystal display (LCD) screen, etc.

[0046] The display screen 21 has a display area for displaying image information, and the display area of ​​the display screen 21 is exposed to facilitate the presentation of images, videos and other information to the user.

[0047] The decorative shell 1 has a display area. Optionally, when the display component 2 is in the first display position, a portion of the at least two displays 21 are opposite to the display area. When the display component 2 switches to the second display position, the remaining displays 21 are opposite to the display area. Optionally, when the display component 2 is in the first display position, both at least two displays 21 are opposite to the display area. When the display component 2 switches to the second display position, both at least two displays 21 are also opposite to the display area, but the positions of each display 21 relative to the display area change.

[0048] If the display area 11 can only display information from a portion of the display screens 21 of at least two display screens 21, the display area can switch between displaying information from different display screens 21 as the display component 2 rotates between the first display position and the second display position; if the display area can display information from all display screens 21, the information from one of the display screens 21 of the display component 2 can be displayed through different parts of the display area as the display component 2 rotates between the first display position and the second display position.

[0049] For example, the decorative shell 1 may have a light-transmitting window, which is the display area 11 of the decorative shell 1. During the rotation of the display component 2 between the first display position and the second display position, different displays 21 are switched to be opposite the light-transmitting window, so that the information displayed on the displays 21 can be observed by the user through the light-transmitting window. When the user needs to view different information through the displays 21, this can be achieved by switching different displays 21 to positions opposite the light-transmitting window of the decorative shell 1.

[0050] For example, during the rotation of the display component 2 between the first display position and the second display position, at least two displays 21 of the display component are respectively opposite to different positions of the display area of ​​the decorative shell 1, so that the user can observe the information displayed by the at least two displays 21 through different positions of the decorative shell 1.

[0051] Optionally, the display component 2 can be rotated relative to the decorative shell 1 manually or by a motor. For example, when a user wants to view different information on different displays 21, they can manually rotate the display component 2 relative to the decorative shell 1. For example, the vehicle can automatically control the rotation of the display component 2 relative to the decorative shell 1 via a motor according to different vehicle states, so that the display component 2 switches between a first display position and a second display position.

[0052] Optionally, the display component 2 may also have a third display position, which may be located between the first and second display positions. This application does not impose any specific restrictions on this.

[0053] It should be noted that at least two displays 21 are arranged side by side on the front side of the rotation axis. The at least two displays 21 can be arranged side by side along a straight line or along a curve. For example, at least two displays 21 are arranged in a row along an arc. This application does not impose any specific restrictions on this.

[0054] Optionally, see Figure 2 and Figure 4 At least two displays 21 can be arranged to follow the rotation trajectory of the display component 2. This ensures a smooth switching effect of the displays 21 when the display component 2 switches between the first and second display positions, and also ensures accurate alignment between the displays 21 and the display area 11, avoiding partial obstruction or overlap caused by inaccurate screen positioning.

[0055] If at least two displays 21 are arranged circumferentially along the axis of rotation, then when the display component 2 rotates in the first display position and the second display position, in order to enable each display 21 to switch to the display area position, the display component 2 needs a large space to rotate. When the space size that the vehicle can provide to the display device 100 is fixed, the size design of the display 21 needs to be reduced accordingly to avoid collisions or interference between the display component 2 and other parts of the vehicle.

[0056] By arranging at least two displays 21 side-by-side on the front side of the rotation axis, the circumferential angle that the display component 2 needs to rotate during the switching between the first and second display positions relative to the decorative shell 1 is relatively small. This reduces the space requirement of the display component 2, especially the space requirement along the longitudinal direction of the vehicle. Thus, when the space available for the display device 100 in the vehicle is fixed, the limitation on the area size of the display 21 can be reduced, allowing for a corresponding increase in the area size of the display 21 to optimize its display effect, improve its clarity, and enhance the user experience.

[0057] In addition, by arranging at least two displays 21 side by side on the front side of the rotation axis, enough space can be left on the other side of the displays 21 for installing other components, such as the drive assembly 3, the circuit board assembly 5, etc., which can effectively avoid mutual interference between internal structures and is conducive to the overall compact design.

[0058] For example, the display component 2 has at least two displays 21, including a first display 211 and a second display 212. When the display device 100 is applied to a vehicle, the vehicle will have various different working states, such as a parking state and a starting state. When the vehicle is in a parking state, the first display 211 of the display component 2 is opposite to the display area 11. The first display 211 is a secondary display. The first display 211 can be used to display information preferred by the driver, such as the status of the entertainment system and multimedia information. When the vehicle switches from the parking state to the starting state, the display component 2 can rotate relative to the decorative shell 1 to switch to the second display 212 being opposite to the display area 11. The second display 212 can be used to display navigation information or vehicle speed information required by the driver during driving.

[0059] According to the embodiments of this application, the display device 100, by arranging at least two displays 21 side by side on the front side of the rotation axis, requires less space when switching between different displays 21 and the display area 11. This helps to reduce the limitation on the arrangement of the display device 100 by the size of the vehicle along its front-rear direction, thereby allowing the area size of the displays 21 to be increased accordingly, so as to optimize the display effect of the displays 21 and improve its display clarity and user experience.

[0060] In some alternative embodiments, the display device 100 is located at the dashboard of the vehicle, and the decorative housing 1 of the display device 100 may be formed as part of the dashboard.

[0061] See Figure 4In some optional embodiments, the display component 2 has at least two displays 21 including a first display 211 and a second display 212. The display area of ​​the second display 212 is larger than that of the first display 211. The first display 211 is a secondary display and can be used to display the status of the entertainment system and multimedia information. The second display 212 is the main display and can be used to display navigation information or vehicle speed and other information.

[0062] See Figures 1-4 In some embodiments, the decorative shell 1 includes a main display area, and at least two displays 21 include a main display and a secondary display. In a first display position, the main display and the main display area are offset; in a second display position, the main display and the main display area are opposite to each other, and the secondary display and the main display area are offset.

[0063] It should be noted that the main display area can be understood as the area where information is shown to the driver. For example, display area 11 and the part directly in front of the driver.

[0064] Optionally, the display area 11 of the decorative shell 1 may only include the main display area, or the display area 11 of the decorative shell 1 may also include the remaining display area outside the main display area. For example, when in the second display position, the sub-display can display information through the remaining display area.

[0065] Optionally, in the first display position, the main display screen and the main display area can be completely or partially offset, and the secondary display screen can be completely or partially opposite to the main display area. Of course, the secondary display screen can also be not opposite to the main display area. This application does not impose specific restrictions on this.

[0066] For example, when the display device 100 is applied to a vehicle, when the driver gets into the vehicle, the display component 2 is in the first display position, and the main display screen and the secondary display screen can display "welcome information" at the same time. Then, after the vehicle is started, the display component 2 switches from the first display position to the second display position according to the driver's status, so that the main display area can provide the driver with the required vehicle status and other information through the main display screen.

[0067] For example, when the display device 100 is applied to a vehicle, during the operation of the vehicle, if the vehicle is in motion, the display component 2 is in the second display position, and the main display area provides the driver with the required navigation information, etc. When the vehicle is parked, the display component 2 switches from the second display position to the first display position, and the main display area can display other preferred information for the driver, such as multimedia information, etc.

[0068] For example, when the display device 100 is applied to a vehicle, in the second display position, the main display area can provide the driver with the required vehicle status and other information through the main display area. The secondary display screen can be in a blocked state at this time, or the secondary display screen can be opposite to the other areas next to the main display area to display the multimedia information required by the front passenger, or the secondary display screen can be opposite to the other areas next to the main display area, but the secondary display screen is in a screen-off state.

[0069] By adjusting the relative positions of the main display area, the main display screen, and the secondary display screen, the display components can precisely control the information display range in different display positions to meet diverse user needs. Furthermore, different information displayed in the main display area can also assist the driver in judging the vehicle's status, such as whether the vehicle is currently parked.

[0070] See Figures 1-4 In some embodiments, the decorative shell 1 further includes a covering area 12 located around the main display area. In a first display position, the main display screen and the covering area 12 are opposite each other; and / or, in a second display position, the secondary display screen and the covering area 12 are opposite each other.

[0071] In the first display position, the main display screen and the covering area 12 are opposite each other; and / or, in the second display position, the secondary display screen and the covering area 12 are opposite each other, which may include the following situations:

[0072] For example, in the first display position, the main display screen and the cover area 12 are opposite each other, and in the second display position, the sub-display screen and the cover area 12 are opposite each other.

[0073] For example, in the first display position, the main display screen and the covering area 12 are opposite each other, while in the second display position, the positional relationship between the secondary display screen and the covering area 12 is not specifically limited in this application.

[0074] For example, in the second display position, the sub-display and the covering area 12 are opposite each other, while in the first display position, the positional relationship between the main display and the covering area 12 is not specifically limited in this application.

[0075] Optionally, if the main display screen or the secondary display screen is not completely blocked by the covered area 12 when it is in a certain display position, the main display screen or the secondary display screen can also be adjusted to the off state to ensure the single-screen display effect of the main display area.

[0076] In this way, the display device 100 can achieve single-screen display functionality, allowing the user to see only one main information interface at any given time, reducing distraction. For example, while driving, the display device 100 is in the second display position, with the main display area only showing vehicle status information from the main display screen, while the secondary display screen is obscured; and when parked, the display component 2 rotates and switches to the first display position, with the main display area showing multimedia information from the secondary display screen, while the main display screen is obscured.

[0077] In some embodiments, the decorative shell 1 further includes a first sub-display area and a second sub-display area arranged side by side on both sides of the main display area. In a first display position, the main display screen and the first sub-display area are opposite to each other; in a second display position, the sub-display screen and the second sub-display area are opposite to each other.

[0078] For example, when the display device 100 is applied to a vehicle, when the driver gets into the vehicle, the display component 2 is in a first display position, with the main display screen and the first secondary display area facing each other, and the secondary display screen and the main display area facing each other. The main display screen and the secondary display screen can simultaneously display a "welcome message" through the first secondary display area and the main display area. Then, after the vehicle is started, the display component 2 switches from the first display position to the second display position according to the driver's status, with the main display screen and the main display area facing each other, and the secondary display screen and the second secondary display area facing each other, so that the main display area can provide the driver with the required vehicle status and other information through the main display screen, while the secondary display screen can display other information preferred by the driver through the second secondary display area, or the secondary display screen can display multimedia information for the front passenger through the second secondary display area, or the secondary display screen can be in a screen-off state to reduce energy consumption.

[0079] By dividing the display area 11 of the decorative shell 1 into sections, different displays 21 can be aligned with different display areas 11, achieving partitioned display and on-demand switching. Users see the corresponding information interface at different rotation angles. This method allows the displayed content to be dynamically adjusted according to scene requirements, improving interaction efficiency.

[0080] See Figure 2 and Figure 4 In some embodiments, at least two displays 21 are curved screens. When the arrangement space of the displays 21 is fixed, the curved screens are beneficial to increasing the display area of ​​the displays 21 and further improving the display effect of the displays 21.

[0081] See Figure 2 and Figure 4 In some embodiments, at least two displays 21 are flat screens, which are easy to form and install, thus improving the production efficiency of the display device.

[0082] See Figure 2 and Figure 4In some embodiments, the display assembly 2 includes a mounting housing 22, on which at least two displays 21 are disposed. The mounting housing 22 is rotatably disposed within the decorative shell 1. The mounting housing 22 provides effective support for the displays 21 and can drive at least two displays 21 to rotate synchronously relative to the decorative shell 1, so as to achieve accurate switching of the relative positions of the different displays 21 and the display area 11 of the decorative shell 1.

[0083] For example, at least two displays 21 can be disposed on the inner wall surface of the mounting housing 22 or on the outer wall surface of the mounting housing 22.

[0084] See Figure 2 and Figure 4 In some embodiments, at least two displays 21 are disposed within the mounting housing 22. The mounting housing 22 and the at least two displays 21 have light-transmitting holes 223 at opposite positions, allowing the content displayed on the displays 21 to be shown through the mounting housing 22. Thus, with at least two displays 21 housed within the mounting housing 22, the mounting housing 22 effectively protects the displays 21. Furthermore, the light-transmitting holes 223 on the mounting housing 22, opposite to the displays 21, prevent the mounting housing 22 from obstructing the display content of the displays 21.

[0085] See Figure 4 In some optional embodiments, the display component 2 further includes a transparent cover plate 23 disposed within the mounting housing 22 and located at the light-transmitting hole 223, the transparent cover plate 23 being used to cover the light-transmitting hole 223. For example, the transparent cover plate 23 may be a glass cover plate 2221.

[0086] See Figure 4 In some embodiments, the mounting housing 22 includes a front housing 221 and a rear cover 222 connected to the front housing 221, with a light-transmitting hole 223 provided in the front housing 221. By configuring the mounting housing 22 into two detachably connected parts, the front housing 221 and the rear cover 222, it is convenient for the inspection and maintenance of the internal components of the mounting housing 22.

[0087] For example, the assembly process of the display device 100 may include the following steps: first, placing at least two displays 21 inside the mounting housing 22, and then connecting the rear cover 222 to the front housing 221 to cover the front housing 221.

[0088] For example, the front shell 221 and the rear cover 222 can be connected together by snap-fit ​​connection, fastening connection or other connection methods.

[0089] See Figure 2 and Figure 4In some embodiments, the display device 100 further includes a driving component 3, which includes a fixed base 31 and a driving member 32 disposed on the fixed base 31. The fixed base 31 and the decorative shell 1 are fixed relative to each other. The rear cover 222 is tractively connected to the driving member 32. The driving member 32 can drive the rear cover 222 to rotate relative to the decorative shell 1, so as to drive the front shell 221 and at least two display screens 21 to rotate relative to the decorative shell 1.

[0090] The fixed base 31 and the decorative shell 1 are fixed relative to each other, so that the fixed base 31 can serve as the installation base for the entire drive system. For example, the fixed base 31 can provide a stable support for the drive component 32.

[0091] For example, the drive unit 32 can be a drive motor, such as a stepper motor or a servo motor, used to output rotational driving force.

[0092] Optionally, the rotation axis of the output shaft of the drive component 32 coincides with the rotation axis of the display component 2, that is, the axis of the output shaft coincides with the first axis. This can reduce the number of transmission components between the drive component 3 and the display component 2, thereby simplifying the assembly steps and reducing production costs.

[0093] By setting the driving component 3, the driving component 3 enables the display component 2 to automatically switch the display screen 21 relative to the decorative shell 1, which is beneficial to improving the interactive convenience and user experience of the display device 100; it can also precisely control the rotation angle of the display component 2 to ensure accurate alignment of the display screen 21 and the display area 11 of the decorative shell 1.

[0094] See Figure 2 and Figure 4 In some embodiments, the fixed base 31 includes a base substrate 311 and a columnar housing 312 disposed on the base substrate 311. The mounting housing 22 is supported on the base substrate 311, and the driving member 32 is disposed in the columnar housing 312. The base substrate 311 can provide a stable mounting surface for the display component 2.

[0095] The rear cover 222 includes a cover plate 2221 and a central housing 2222. The central housing 2222 covers the cylindrical housing 312. The driving member 32 can drive the rear cover 222 to rotate around the cylindrical housing 312 relative to the decorative housing 1, so as to drive the front housing 221 and at least two displays 21 to rotate around the cylindrical housing 312 relative to the decorative housing 1.

[0096] It should be noted that the cylindrical shell 312 can be a closed shell or a semi-closed shell, that is, the cylindrical shell 312 can have an opening. Correspondingly, the central shell 2222 is a semi-closed shell, and the central shell 2222 has an opening so that the center of gravity shell can cover the cylindrical shell 312.

[0097] In this way, the central housing 2222 of the back cover 222 is directly fitted onto the cylindrical housing 312, forming a compact rotating structure, saving space and improving structural strength. In addition, the cylindrical housing 312 can serve as the rotation center of the back cover 222, and thus as the rotation center of the display component 2, so that the torque transmitted from the driving component 32 to the display component 2 is uniform, which is beneficial to improving the rotational stability of the display component 2.

[0098] See Figure 4 In some optional embodiments, the front shell 221 has a clearance notch at one end facing the rear cover 222. The clearance notch can accommodate the central shell 2222, so that the front shell 221 and the rear cover 222 can be fitted together to avoid a large gap between them.

[0099] See Figure 4 In some embodiments, the display device 100 further includes a ball bearing slide rail 4, which is disposed between the base substrate 311 and the mounting housing 22. The extending direction of the ball bearing slide rail 4 is consistent with the rotation direction of the display component 2. The ball bearing slide rail 4 is disposed between the base substrate 311 and the mounting housing 22, and the balls of the ball bearing slide rail 4 are distributed along the rotation trajectory of the display component 2, thereby forming a rolling guide path for the ball bearing slide rail 4 to guide and assist the display component 2 in rotating relative to the base substrate 311.

[0100] By setting the ball slide rail 4, the ball slide rail 4 can provide additional rolling support for the display component 2, and use rolling contact instead of sliding friction to significantly reduce frictional resistance during rotation and improve the smoothness of rotation of the display component 2.

[0101] See Figure 4 In some embodiments, the display device 100 further includes a circuit board assembly 5 and a flexible electrical connector 6, the flexible electrical connector 6 being connected between the circuit board assembly 5 and at least two display screens 21. The circuit board assembly 5 and the fixed base 31 are fixed relative to each other, and the rear cover 222 is provided with a clearance hole 2223, through which the flexible electrical connector 6 passes.

[0102] The circuit board assembly 5 serves as the core control unit of the entire display device 100. It processes various data from the vehicle (such as speed and navigation information) and converts this data into visual images, which are then output to the corresponding display screen 21. It may also include power management and communication interface modules, forming the basis for ensuring the normal operation of the display device 100.

[0103] Furthermore, since the display assembly 2 needs to rotate around the cylindrical housing 312 relative to the decorative housing 1, traditional rigid wires cannot meet such movement requirements. The flexible electrical connector 6 can not only withstand multiple bends without damage, but also provide a reliable electrical connection in a limited space, ensuring unimpeded communication between each display screen 21 and the circuit board assembly 5 even in a rotating state.

[0104] For example, the flexible electrical connector 6 can be a flexible printed circuit (FPC).

[0105] By setting up the flexible electrical connector 6, the flexible electrical connector 6 can bend naturally according to the rotation trajectory of the display component 2, reducing the need for additional support structures and making the overall design simpler and more compact; and the flexible electrical connector 6 can maintain a stable electrical connection during rotation, ensuring stable and reliable signal transmission.

[0106] For example, the assembly process of the display device 100 may include the following steps:

[0107] First, fix the circuit board assembly 5 onto the mounting base 31, ensuring that it is correctly positioned and securely installed;

[0108] Next, install the drive unit 32 (such as a motor) into the cylindrical housing 312 and ensure that it can operate normally;

[0109] Next, the ball bearing slide rail 4 is installed on the base plate 311;

[0110] Next, at least two displays 21 are installed into the front housing 221, ensuring that each display 21 is accurately aligned with its corresponding light-transmitting hole 223, and one end of the flexible electrical connector 6 is connected to the display 21.

[0111] Next, the front shell 221 and the rear cover 222 are combined to form a complete mounting housing 22, and the other end of the flexible electrical connector 6 is made to pass through the clearance hole 2223 of the rear cover 222.

[0112] Next, the integrated mounting housing 22, display screen 21 and flexible electrical connector 6 are installed onto the fixed base 31, and the other end of the flexible electrical connector 6 is connected to the circuit board assembly 5.

[0113] Finally, the decorative shell 1 is placed over the mounting shell 22 and the fixed base 31, and one of the display screens 21 and the display area 11 of the decorative shell 1 are opposite each other;

[0114] Thus, the display device 100 is assembled.

[0115] For example, the display device 100 is applied to a vehicle that has multiple operating states. In these multiple operating states, the display component 2 switches between a first display position and a second display position so that different displays 21 and display areas 11 are opposite each other.

[0116] Specifically, the at least two displays 21 of the display component 2 may include a first display 211 and a second display 212. When the display device 100 is applied to a vehicle, the vehicle's various operating states may include a parking state and a starting state. For example, when the vehicle is in a parking state, the display component 2 is in a second display position, with the first display 211 of the display component 2 facing the display area 11. The first display 211 can be used to display information preferred by the driver, such as the entertainment system status and multimedia information. When the vehicle switches from a parking state to a starting state, the display component 2 can rotate relative to the decorative shell 1 to switch from the second display position to the first display position. The second display 212 faces the display area 11, and the second display 212 can be used to display navigation information or vehicle speed information required by the driver during driving. In this way, the display device 100 can meet the diverse display needs of users. Furthermore, during vehicle operation, the driver can also determine the vehicle's current status through the information displayed on the corresponding displays 21 in the display area 11.

[0117] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
