[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0061] Please refer to Figure 1 and Figure 2 This application provides a display device, comprising:

[0062] The first display screen 1 includes a first housing 11 and a first display module 12 housed within the first housing 11.

[0063] At least one second display screen 2 is located on one side of the first display screen 1 along a first direction, the first direction being parallel to the extension surface of the display surface of the first display module 12. The second display screen 2 includes a second housing 21 and a second display module 22 housed within the second housing 21. The second display module 22 is signal-connected to the first display module 12.

[0064] At least one set of rotating components, the second housing 21 is rotatably connected to the first housing 11 via the rotating components.

[0065] The display device provided in this application embodiment can be applied to the field of intelligent vehicles. It includes a first display screen 1, at least one second display screen 2, and at least one set of rotating components. The second display screen 2 is located on one side of the first display screen 1. The second display module 22 of the second display screen 2 is signal-connected to the first display module 12 of the first display screen 1. The second housing 21 of the second display screen 2 is rotatably connected to the first housing 11 of the first display screen 1 through the rotating components. That is, the second display screen 2 is assembled on the first display screen 1 and can rotate on the first display screen 1. In this way, the first display screen 1 can be used as the main screen and the second display screen 2 can be used as an auxiliary screen. This allows the driver to flexibly adjust the screen angle of the second display screen 2 and customize various personalized functions according to their own needs, thereby ensuring the driver's best vision and operation convenience, and ensuring the driver's safe driving.

[0066] It should be noted that the first direction mentioned above is any direction parallel to the extension surface of the display surface of the first display module. The specific position of the second display screen is not limited here and depends on the actual situation.

[0067] Specifically, the aforementioned display device can be applied in the field of intelligent vehicles, such as... Figure 3 The diagram shown illustrates the installation of the display device a inside a vehicle in this embodiment; alternatively, the display device can also be applied to other display fields, without limitation, depending on the actual situation.

[0068] The first display screen 1 and the second display screen 2 can both be touch screens, and passengers can control different functions of the vehicle by touching the first display screen 1 and the second display screen 2.

[0069] Specifically, the display device may have one or more second display screens 2; if the display device includes multiple second display screens 2, the multiple second display screens 2 may be located on one or more sides of the first display screen 1, without limitation, depending on the actual situation.

[0070] The second display screen 2 can be smaller than the first display screen 1, providing auxiliary display. The design of the auxiliary screen takes into account the needs of different drivers and passengers. They can be independently adjusted at multiple angles to adapt to various sitting postures, heights, and viewing habits, achieving a comfortable human-machine integrated operating experience, making operation more convenient and safer.

[0071] For example, the tilt state of the first display screen 1 when installed inside the vehicle can be as follows: Figure 4As shown, the orientation of the display panel of the second display screen 2 can be the same as the orientation of the display surface of the first display screen 1. To accommodate the needs of different drivers and passengers, the rotation angle of the second display screen 2 can be adjusted, such as... Figure 5 As shown, the second display screen 2 can be rotated upwards, or as... Figure 6 As shown, the second display screen 2 is rotated downwards so that the orientation of the display surface of the second display screen 2 is different from that of the display surface of the first display screen 1, which can adapt to various sitting postures, heights and viewing habits, and achieve a comfortable human-computer integrated operation experience.

[0072] Specifically, such as Figure 2 and Figure 3 As shown, in the display device, the first display screen 1 can be located in the center of the vehicle's dashboard and used as the main screen. Multiple second display screens 2 can be arranged side-by-side below the first display screen 1 and used as auxiliary small screens; alternatively, the multiple second display screens 2 can be located above, to the left, or to the right of the first display screen 1; or, the multiple second display screens 2 can be positioned on different sides of the first display screen 1. The specific location of the second display screens 2 is not limited here and depends on the actual situation.

[0073] It should be noted that the top, bottom, left and right sides of the first display screen 1 are the positions relative to the first display screen 1 when it is in normal use.

[0074] The first display screen 1 can comprehensively display icons for different functions, such as music, maps, settings, and weather. To further enhance the user experience, the second display screen 2 can be configured to perform specific in-vehicle infotainment shortcuts, such as any one of the following modules: clock, weather forecast, emergency alarm, music, and radio. Different second displays 2 can be configured to perform different in-vehicle infotainment shortcuts. This personalized setting avoids the inconvenience of searching for scattered function buttons on traditional in-vehicle infotainment interfaces, thereby reducing the possibility of driver distraction and improving driving safety.

[0075] In this embodiment, the display device may include only one set of rotating components, and the second housing 21 of one or more second display screens 2 may be rotatably connected to the first housing 11 of the first display screen 1 through one set of rotating components; alternatively, the display device may include multiple rotating components, with multiple second display screens 2 corresponding one-to-one with multiple rotating components, and the second housing 21 of the second display screen 2 rotatably connected to the first housing 11 of the first display screen 1 through the corresponding rotating components, enabling independent rotation of each second display screen 2 on the first display screen 1; alternatively, some of the second display screens 2 may be rotatably connected to the first display screen 1 through corresponding rotating components, while other parts of the second display screens 2 may be rotatably connected to the first display screen 1 through the same set of rotating components. In this embodiment, the number of rotating components is not limited and depends on the actual situation.

[0076] In the embodiments of this application, such as Figures 7 to 10 As shown, the rotating assembly 3 may include a rotating shaft 31 and at least one rotating plate 32. The rotating shaft 31 is fixedly connected to the first housing 11. The rotating plate 32 can rotate around the axis of the rotating shaft 31. The rotating plate 32 may include a connecting part 320 and a supporting part 322. The connecting part 320 is connected to the rotating shaft 31, and the supporting part 322 is connected to the second housing 21 of the second display screen 2.

[0077] In the above-mentioned display device, a rotating shaft 31 can be connected to the first housing 11 of the first display screen 1. A rotating plate 32 can be provided on the rotating shaft 31. The connecting part 320 of the rotating plate 32 is connected to the rotating shaft 31. The bearing part 322 of the rotating plate 32 can support the second display screen 2. The structure is simple and easy to manufacture.

[0078] Specifically, if the display device includes a set of rotating components 3, the rotating components 3 may include a rotating shaft 31, and one or more rotating plates 32 may be provided on the rotating shaft 31. Each rotating plate 32 may carry a second display screen 2, so that one or more second display screens 2 can be rotatably connected to the first display screen 1 through a set of rotating components 3, and each second display screen 2 can rotate independently.

[0079] like Figure 7 and Figure 8 As shown, a rotating shaft 31 is mounted on the lower side of the first housing 11 of the first display screen 1. Multiple rotating plates 32 are connected to the rotating shaft 31. Multiple second display screens 2 are rotatably connected to the rotating shaft 31 through corresponding rotating plates 32, enabling each second display screen 2 to rotate independently on the first display screen 1. The overall design integrates the main screen of the vehicle infotainment system with a set of auxiliary small screens, realizing the stable construction of the entire in-vehicle intelligent control system.

[0080] Optionally, if the display device includes multiple second display screens 2, and the rotating component 3 corresponds one-to-one with each of the second display screens 2, then it can be configured as follows: Figure 9 and Figure 10 As shown, the rotating assembly 3 includes a rotating shaft 31 and a rotating plate 32. The rotating shaft 31 can be fixed on the first housing 11 of the first display screen 1. The rotating plate 32 can be rotatably connected to the rotating shaft 31. The second display screen 2 can be set on the rotating plate 32 in the corresponding rotating assembly 3, so that the second display screen 2 can be rotatably connected to the first display screen 1 through the corresponding rotating assembly. Furthermore, each second display screen 2 can rotate independently.

[0081] The number of rotating plates 32 on the rotating assembly 3 is not limited here and can be determined according to the actual situation.

[0082] In the embodiments of this application, such as Figures 7 to 10 As shown, the first housing 11 may include multiple side plates arranged around the first display module 12; the rotating shaft 31 can be connected to any one of the side plates, and the extension direction of the rotating shaft 31 can be the same as the extension direction of the side plate it is connected to. The structure is simple and can facilitate the second display screen 2 to be set on one side of the first display screen 1.

[0083] For example, such as Figure 7 and Figure 8 As shown, the first housing 11 of the first display screen 1 may include four side plates, namely an upper side plate, a lower side plate, a left side plate and a right side plate. The rotating shaft 31 may be located on the lower side of the first display screen 1. The rotating shaft 31 is connected to the lower side plate. The extension direction of the rotating shaft 31 is the same as the extension direction of the lower side plate. Multiple rotating plates 32 are rotatably connected to the rotating shaft 31. The rotating plates 32 carry the second display screen 2, thereby realizing the rotatable connection between the second display screen 2 and the lower side of the first display screen 1.

[0084] Optionally, the extension direction of the rotating shaft 31 can also be parallel to the first direction and perpendicular to the extension direction of the side plate connected to it. The structure is simple and can facilitate the second display screen 2 to be set on one side of the first display screen 1.

[0085] For example, such as Figure 11 As shown, multiple rotating shafts 31 can be connected to the left side plate of the first housing 11. The extension direction of each rotating shaft 31 can be parallel to the first direction and perpendicular to the extension direction of the left side plate. A rotating plate 32 is connected to each rotating shaft 31. The second display screen 2 can be rotatably connected to the rotating shaft 31 through the rotating plate 32, thereby realizing the rotatable connection between each second display screen 2 and the left side of the first display screen 1.

[0086] Optionally, the connection position of the rotating shaft 31 in the rotating assembly and the extension direction of the rotating shaft 31 can also be other structures, which are not limited here and can be determined according to the actual situation.

[0087] In the embodiments of this application, such as Figure 12 As shown, the rotating assembly 3 may also include at least one fixed seat 33, and the end of the rotating shaft 31 can be connected to the first housing 11 through the fixed seat 33. The structure is simple and easy to set up.

[0088] Specifically, one end of the rotating shaft 31 is fixedly connected to the first housing 11 via a fixing seat 33, or both ends of the rotating shaft 31 are fixedly connected to the first housing 11 via fixing seats 33. No limitation is imposed here; it depends on the actual situation. Figure 7 and Figure 9 As shown, the extension direction of the rotating shaft 31 is parallel to the extension direction of the lower side plate of the first housing 11, and the two ends of the rotating shaft 31 can be connected to the lower side plate of the first housing 11 through the connecting seat.

[0089] Specifically, such as Figure 12 and Figure 13 As shown, the fixing base 33 may include a fixing plate 331 and a fixing rod 332. One side of the fixing plate 331 is connected to the first housing 11, the other side of the fixing plate 331 is connected to the first end of the fixing rod 332, and the second end of the fixing rod 332 is connected to the end of the rotating shaft 31. The structure is simple and easy to manufacture.

[0090] Specifically, both ends of the rotating shaft 31 are connected to the first housing 11 via the fixing seat 33. The fixing plate 331 can be connected to the side plate of the first housing 11 via bolts. The first end of the fixing rod 332 can be connected to the side of the fixing plate 331 away from the side plate, and the second end of the fixing rod 332 can be connected to the end of the rotating shaft 31.

[0091] The second end of the fixing rod 332 may have a bolt hole 333, and the second end of the fixing rod 332 may be fixedly connected to the end of the rotating shaft 31 by a bolt passing through the bolt hole 333.

[0092] The fixing base 33 can be designed as a single piece, which is simple in structure and easy to implement.

[0093] Specifically, in order to enhance the overall structural strength, the area where the fixing plate 331 connects to the fixing rod 332 in the fixing seat 33 can be provided with reinforcing ribs 334.

[0094] In the embodiments of this application, Figure 12 and Figure 14 As shown, the connecting part 320 of the rotating plate 32 can be a sleeve part 321. The sleeve part 321 is sleeved on the rotating shaft 31. The sleeve part 321 can rotate around the axis of the rotating shaft 31. The structure is simple and easy to manufacture, and can realize the stepless rotation of the second display screen 2.

[0095] Specifically, the inner wall of the sleeve portion 321 of the rotating plate 32 can be interference-fitted with the outer wall of the rotating shaft 31, which can both enable the second display screen 2 on the rotating plate 32 to rotate around the rotating shaft 31 and ensure that the second display screen 2 on the rotating plate 32 stops rotating after rotating to the required angle.

[0096] Alternatively, the connecting part 320 of the rotating plate 32 can also be other structures, which are not limited here and depend on the actual situation.

[0097] Specifically, Figure 15 and Figure 16 As shown, the inner wall of the sleeve portion 321 may have a first limiting groove 3211, and the outer wall of the rotating shaft 31 may have a limiting tooth 311. The limiting tooth 311 can be inserted into the first limiting groove 3211 to limit the rotation angle range of the rotating plate 32. This can ensure the stepless rotation of the second display screen 2 while limiting the rotation angle of the second display screen 2.

[0098] like Figure 15 The limiting teeth 311 on the rotating shaft 31 are inserted into the first limiting groove 3211 of the sleeve portion 321, and the limiting teeth 311 abut against the first side wall of the first limiting groove 3211; when the second display screen 2 is manually rotated, the limiting teeth 311 can move within the first limiting groove 3211 until they abut against the second side wall of the first limiting groove 3211, as described above. Figure 17 As shown, the second sidewall is opposite to the first sidewall. The rotation angle range of the rotating plate 32 can be limited by the cooperation between the limiting tooth 311 and the first limiting groove 3211.

[0099] In the embodiments of this application, such as Figure 14 As shown, the support portion 322 of the rotating plate 32 may have at least one weight-reducing hole 3221, which can reduce the weight of the display device and achieve a lightweight effect.

[0100] like Figure 14 As shown, a weight-reducing hole 3221 can be provided in the edge region of the support part 322 to achieve a lightweight effect. Alternatively, a weight-reducing hole can also be provided in the middle region of the support part 322; there is no limitation here, and it depends on the actual situation. The shape of the weight-reducing hole 3221 can be U-shaped or other shapes; there is no limitation here.

[0101] Specifically, the rotating plate 32 can be made of materials such as aluminum and stainless steel, which can achieve a lightweight effect.

[0102] In this embodiment of the application, the second display module 22 and the first display module 12 can be connected by a transmission line to realize signal transmission between the second display module 22 and the first display module 12.

[0103] To achieve the connection between the second display module 22 and the first display module 12, such as Figure 12 , Figure 14 , Figure 17 , Figure 18 The first housing 11 may have a wire harness hole, the fixing base 33 may have a wire harness groove 335, the rotating shaft 31 has a wiring cavity 312, the rotating plate 32 has a first wiring hole 3212, and the second housing 21 has a second wiring hole 211. The wire harness hole, wire harness groove 335, wiring cavity 312, first wiring hole 3212 and second wiring hole 211 are sequentially connected and can cooperate to form a wiring channel. The transmission line is routed along the wiring channel, so that the connection between the first display module 12 and the second display module 22 can realize the hidden wiring of the transmission line, which is beneficial to improving the aesthetics of the display device.

[0104] In the above-mentioned display device, the first end of the transmission line is connected to the first display module 12, and the second end of the transmission line first passes through the wire harness hole of the first housing 11, then runs along the wire harness groove 335 on the fixed base 33, enters one end of the wiring cavity 312 of the rotating shaft 31, and then passes out from the other end of the wiring cavity 312, passes through the first wiring hole 3212 on the rotating plate 32 and the second wiring hole 211 on the second housing 21, and connects to the second display module 22.

[0105] Specifically, the transmission line can be a single signal transmission line or multiple interconnected signal transmission lines; there are no restrictions here, and it depends on the actual situation.

[0106] In addition, the first display module 12 can supply power to the second display module 22. The first display module 12 can supply power to the second display module 22 through a power supply line, which can also be routed along the wiring channel.

[0107] Specifically, the first display module 12 and the second display module 22 can be liquid crystal display modules (LCD), organic light-emitting diode display modules (OLED), or micro diode display modules, etc. There are no restrictions here, and it depends on the actual situation.

[0108] Specifically, such as Figure 19 and Figure 20As shown, the first display module 12 can be an organic electroluminescent display module. The first display module 12 may include a back plate 121, a first display panel 122, a first polarizer 123, a first printed circuit board 124, a second printed circuit board 125, a first flexible circuit board 126, and a second flexible circuit board 127. The back plate 121 is located on the non-light-emitting side of the first display panel 122, the first polarizer 123 is located on the light-emitting side of the first display panel 122, the first printed circuit board 124 and the second printed circuit board 125 are located on the side of the back plate 121 away from the first display panel 122, the first end of the first flexible circuit board 126 is connected to the first display panel 122, the second end of the first flexible circuit board 126 is connected to the first printed circuit board 124, the first end of the second flexible circuit board 127 is connected to a connector on the first printed circuit board 124, and the second end of the second flexible circuit board 127 is connected to a connector 128 on the second printed circuit board 125.

[0109] Specifically, the first display screen 1 may also include a first cover plate 13, which can cooperate with the first housing 11 to form a first accommodating cavity. The first display module 12 is located in the first accommodating cavity, and the first polarizer 123 of the first display module 12 can be connected to the first cover plate 13 through the first optical adhesive layer 129.

[0110] Alternatively, the first display screen 1 can also have other structures, which are not limited here and depend on the actual situation.

[0111] like Figure 19 and Figure 21 As shown, the second display module 22 can be an organic electroluminescent display module, and its structure is similar to that of the first display module 12.

[0117] When the second display screen 2 is located at the second work position relative to the button 5, the second display screen 2 can press the button 5.

[0118] In the aforementioned display device, a physical button 5 can be provided on the support part 322, and the second display screen 2 can be located above the physical button 5. The user can press the button 5 by pressing the second display screen 2, which can trigger the function of the corresponding button 5. That is, a hidden button is provided, which allows the user to perform mechanical blind operation. The traditional physical button is intelligently combined with the modern technological display and rotation structure, providing the best touch angle operation experience for drivers and passengers, and avoiding safety accidents caused by the driver looking down at the screen to operate and analyze.

[0119] Specifically, different areas of the support unit 322 may have physical buttons 5, allowing users to perform mechanical blind operation of different button 5 functions by pressing different areas of the second display screen 2. The functions of the physical buttons 5 can be customized and are not limited here, depending on the actual situation.

[0120] For example, each of the left and right areas of the support unit 322 has a button 5. When the left side of the second display screen 2 is pressed, the left button 5 can be pressed, and when the right side of the second display screen 2 is pressed, the right button 5 can be pressed.

[0126] Specifically, the second display screen 2 and the support unit 322 can be connected by multiple sets of elastic components. These elastic components can be arranged in different areas. When the user is not pressing the second display screen 2, the multiple sets of elastic components can support the second display screen 2, preventing the second display screen 2 from pressing the button 5 and ensuring the stability of the connection between the second display screen 2 and the support unit 322. When the second display screen 2 is manually pressed, the multiple sets of elastic components can return the second display screen 2 to its first working position. In addition, the elastic components can improve the feel when the user presses the second display screen 2, thus enhancing the user experience.

[0127] When the second display screen 2 is not pressed by external force, the second display screen 2 can contact the button 5 without pressing the button 5. This reduces the distance between the second display screen 2 and the button 5, making it easier for the user to press the button 5 after pressing the second display screen.

[0128] Specifically, in order to ensure the connection between the support part 322 and the second display screen 2, the support part 322 can be connected to the second housing 21 of the second display screen 2 through an elastic component.
