Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0060] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0061] The following is for reference. Figures 1-14 A display device 100 according to an embodiment of the present invention is described.

[0062] like Figures 1-13 As shown, a display device 100 according to some embodiments of the present invention includes: a base 10, a display component 20 and a driving mechanism 30. The display component 20 is disposed on the base 10 and is used to display image information.

[0063] The driving mechanism 30 is mounted on the base 10. The driving mechanism 30 includes a driving component, a sliding member 34, and a transmission component 35. The sliding member 34 is connected to the display component 20 via the transmission component 35. The driving component, mounted on the base 10, drives the sliding member 34 to move, thereby switching the display component 20 between a convex state, a planar state, and a concave state. In other words, the driving mechanism 30 can deform the display component 20, changing its radius of curvature, so that the display component 20 can switch between a convex state (…). Figure 1 As shown), planar state ( Figure 2 (as shown) and concave state ( Figure 3 Switch between (as shown).

[0064] Display component 20 can be used to display navigation information, multimedia entertainment, and vehicle information (e.g., vehicle speed, fuel level, and coolant temperature). Display component 20 can be a flexible display component, allowing it to change its radius of curvature through deformation.

[0065] The display component 20 extends along the first direction F1. The display component 20 can be in a planar state that is completely parallel to the first direction F1, or it can be in a curved state that extends approximately along the first direction F1, such as in a convex state or a concave state.

[0066] like Figure 2 and Figure 5 As shown, when the display component 20 is in a planar state, all positions of the display component 20 are parallel to a mounting plane, and the display component 20 is suitable for displaying navigation and traffic information, etc. Figure 3 and Figure 6 As shown, when the display component 20 is in a recessed state, in the thickness direction of the display device 100 (e.g., ... Figure 6 As shown in the third direction (F3), the two ends of the display component 20 are farther away from the driving mechanism 30 than the middle position of the display component 20. The display component 20 can effectively reduce screen reflection, improve screen clarity and readability, and provide a better user experience; such as Figure 1 and Figure 4 As shown, when the display component 20 is in a convex state, in the thickness direction of the display device 100 (e.g., ... Figure 4 On the third-party F3 shown, the two sides of the display component 20 are closer to the drive mechanism 30 than the center of the display component 20. This allows the display component 20 to expand the user's field of vision, making it easier for the user to view vehicle information. At the same time, with the display component 20 protruding outward, it can highlight some important information (such as vehicle speed and fuel level), improving user readability and reducing the risk of distraction while driving.

[0067] Therefore, the display component 20 can change its radius of curvature according to the user's different visual preferences and the needs of different scenarios, so as to switch between convex, planar and concave states.

[0068] Here, the driving component drives the slider 34 to move, that is, the slider 34 moves in a straight line. The movement of the slider 34 drives the transmission component 35 to move or deform, switching the state of the display component 20. The movement of the slider 34 is easy to control and can improve the reliability of the display component 20 when switching states.

[0069] According to an embodiment of the present invention, the display device 100 is mounted on the base 10 via a drive mechanism 30 and connected to the display component 20. The drive mechanism drives the slider 34 to move, thereby causing the display component 20 to deform via the transmission component 35, thus changing the state of the display component 20. The display component 20 can change its radius of curvature according to different scenarios, and the display component 20 can be applied to a wide range of scenarios, improving the user's sensory comfort and user experience. Moreover, the overall structure is simple, and the slider 34 can be driven by the drive mechanism, improving the convenience of use and further enhancing the user experience.

[0070] like Figures 4-6 As shown, in some embodiments, the two ends of the display component 20 in the first direction F1 are movably connected to the base 10, and the middle part of the display component 20 is connected to the transmission component 35. The driving component drives the sliding member 34 to move, thereby moving the middle part of the display component 20 to switch the state of the display component 20. Here, the middle part includes any position between the two ends of the display component 20, which can be the exact center or any position off the exact center. Thus, the base 10 can provide a stable support point for the entire display component 20, ensuring stability and reliability during the driving process. For example, when the display component 20 is in a planar state, under the action of the driving component, the middle part of the display component 20 moves forward along the third direction F3, causing the display component 20 to switch to an outward convex state. The middle part of the display component 20 moves backward along the third direction F3, causing the display component 20 to switch to an inward concave state.

[0071] like Figures 1-7 As shown, the first direction F1 is the left-right direction, the second direction F2 is the up-down direction, and the third direction F3 is the front-back direction. The left and right ends of the display component 20 are connected to the base 10, and the middle part in the left-right direction can move back and forth, thereby realizing the switching between various display states such as convex, flat or concave.

[0072] like Figure 4 As shown, in some embodiments, the slider 34 includes two sliders symmetrically arranged along the centerline of the display assembly 20 in the first direction F1, thereby maintaining the balance and stability of the display assembly 20 during deformation. Additionally, the transmission assembly includes two corresponding transmission assemblies arranged opposite each other, where the projections of the two transmission assemblies along the second direction F2 can be symmetrical. The slider 34 here can be a slider, which has a simple structure and is easy to manufacture and install.

[0073] like Figure 4As shown, in some embodiments, the driving assembly includes a driving member 31 and a lead screw 33. The lead screw 33 is rotatably mounted on the base 10. A sliding member 34 is threadedly engaged with the lead screw 33. The driving member 31 drives the lead screw 33 to rotate, thereby moving the sliding member 34. When the display assembly 20 is in a planar state, the rotation axis of the display assembly 20 and the lead screw 33 are parallel. The rotation axis of the lead screw 33 is parallel to the first direction F1, that is, the lead screw 33 extends along the first direction F1. The sliding member 34 is threadedly engaged with the lead screw 33, thereby allowing the sliding member 34 to move along the first direction F1. This ensures that the direction and stroke of the sliding member 34 do not occupy the thickness direction of the display assembly 20 (i.e., the thickness direction). Figure 4 The space on the third direction (F3) shown can be reduced, thereby reducing the space occupied by the thickness of the whole device and making the thickness of the entire display device 100 thinner.

[0074] like Figure 4 and Figure 5 As shown, in some embodiments, the lead screw 33 is provided with a first threaded section 331 and a second threaded section 332. The first threaded section 331 and the second threaded section 332 rotate in opposite directions. The sliding member 34 includes two members, one of which is threadedly engaged with the first threaded section 331 and the other is threadedly engaged with the second threaded section 332. The driving member 31 drives the lead screw 33 to rotate, causing the two sliding members 34 to move closer or further away from each other. The transmission component 35 moves or deforms, causing the display component 20 to switch states. By providing two threaded sections with opposite rotation directions on the lead screw 33, the two sliding members 34 can move synchronously, and the movement of the two sliding members 34 can be symmetrical with respect to the center of the display component 20, thereby further maintaining the balance and stability of the display component 20 during the deformation process.

[0075] like Figure 5 and Figure 6 As shown, in some embodiments, the base 10 is provided with at least one optical rod 11, which is arranged parallel to the lead screw 33. The slider 34 also has a smooth hole, and the slider 34 slides with the optical rod 11 through the smooth hole, thereby preventing the slider 34 from rotating and improving the stability of the slider 34's movement. Of course, a slide rail can also be provided on the base 10, and the slider 34 slides on the slide rail.

[0076] like Figure 6 As shown, a guide rod 11 is provided on each of the opposite sides of the lead screw 11 in the radial direction. The slider 34 slides with the two guide rods 11, thereby further improving the sliding stability of the slider 34.

[0077] like Figure 4As shown, in some embodiments, the lead screw 33 is provided with a rotating gear 333, and the driving component 31 includes a driving motor 311 and a driving gear 312. The driving gear 312 meshes with the rotating gear 333. When the driving motor 311 works, it causes the driving gear 312 to rotate, thereby driving the lead screw 33 with the rotating gear 333 to rotate. This realizes the driving of the lead screw 33 to rotate. The overall structure is simple, and with the cooperation of the driving gear 312 and the rotating gear 333, it is easy to control the rotation speed of the lead screw 33.

[0078] Of course, the output shaft of the drive motor 311 can also directly drive the lead screw 33 to rotate, for example, the two can be connected by a coupling.

[0079] like Figure 4 As shown, in some embodiments, the rotating gear 333 is located at one end of the lead screw 33, the drive motor 311 is located on one side of the lead screw 33 in its axial direction, and the drive gear 312 is located on one side of the rotating gear 333 in its radial direction. Thus, the drive motor 31 and the lead screw 33 are arranged along the first direction F1, thereby ensuring that the arrangement of the drive motor 31 does not occupy the thickness direction of the display component 20 (i.e.,...). Figure 4 The space on the third direction (F3) shown can be reduced, thereby reducing the space occupied by the thickness of the whole device and making the thickness of the entire display device 100 thinner.

[0080] like Figure 14 As shown, in some embodiments, the transmission assembly 35 includes a first movable member 354, which is rotatably connected to the sliding member 34 and the display assembly 20. The first movable member 354 can be a rod, a plate, or other structures. The sliding member 34 is connected to the display assembly 20 through the first movable member 354, which can simplify the overall structure and reduce the number of parts. This can reduce costs and also reduce the space occupied by the transmission assembly 35, which can reduce the thickness of the entire machine to a certain extent, making the entire display device 100 thinner.

[0081] like Figure 14 As shown, in some embodiments, the first movable member 354 is rotatably connected to the slider 34 via a first movable shaft 3541. The first movable shaft 3541 includes two shafts arranged opposite each other along a second direction F2. The two first movable shafts 3541 are located on both sides of the slider 34 in the second direction F2, where the second direction F2 is the axial direction of the first movable shaft 3541. Thus, each slider 34 is connected to the display assembly 20 via a first movable member 354, and the first movable member 354 can be rotatably connected to the upper and lower sides of the slider 34, improving the reliability of the connection between the first movable member 354 and the slider 34. At the same time, it can avoid rotational interference between the first movable member 354 and the slider 34, thereby improving the reliability and stability of the display assembly 20 during deformation.

[0082] In some embodiments, the first movable member 354 is rotatably connected to the display component 20 via a second movable shaft. The second movable shaft includes two members arranged opposite each other along a second direction F2, where the second direction F2 is the axial direction of the second movable shaft. Thus, each sliding member 34 is connected to the display component 20 via a first movable member 354, and the first movable member 354 can have two rotatable connection points with the display component 20, thereby improving the reliability of the connection between the first movable member 354 and the display component 20, and further improving the reliability and stability of the display component 20 during deformation.

[0083] In some examples, the display component 20 is connected to two sliders 34 via two first movable members 354. The two first movable members 354 can be rotatably connected to the display component 30 via their corresponding second movable axes, and the axes of the two second movable axes are collinear. Alternatively, the two first movable members 354 can be rotatably connected to the display component 30 via a second movable axis, thereby further simplifying the structure and reducing manufacturing costs.

[0084] like Figure 14 As shown, in some embodiments, the display component 20 extends along the first direction F1, and the first movable member 354 includes two members. The two first movable members 354 are arranged opposite each other along the center line of the display component 20 in the first direction F1. The second direction F2 is perpendicular to the first direction F1. That is, the display component 20 is connected to two sliding members 34 through the two first movable members 354. The two sliding members 34 move closer to each other or further away from each other, causing the display component 20 to deform, thereby improving the stability of the display component 20 during the deformation process.

[0085] In some embodiments, the transmission assembly 35 further includes a second movable member, which is arranged opposite to the first movable member 354 along the second direction F2, and the second movable member is rotatably connected to the slider 34 and the display assembly 20 respectively. That is, each slider 34 is connected to the display assembly 20 through the first movable member 354 and the second movable member. By providing two movable members arranged opposite to each other in the second direction F2, interference between the two movable members and the slider 34 can be avoided, and the stability of the display assembly 20 during deformation can be improved.

[0086] like Figures 4-6As shown, in some embodiments, the transmission assembly 35 includes a first transmission member 351, a second transmission member 352, and a third transmission member 353. The first end of the first transmission member 351 is rotatably connected to the base 10, the second end of the first transmission member 351 is rotatably connected to the first end of the second transmission member 352, the second end of the second transmission member 352 is rotatably connected to the display assembly 20, the first end of the third transmission member 353 is rotatably connected to the slider 34, and the second end of the third transmission member 353 is rotatably connected to the first transmission member 351. Thus, the slider 34 is connected to the display assembly 20 through three transmission members, and the display assembly 20 can be connected to the base 10 through two transmission members. Therefore, with the cooperation of multiple transmission members, the probability of the display assembly 20 shaking during deformation can be reduced, and the stability during deformation can be improved.

[0087] like Figure 8 As shown, in some embodiments, the first transmission member 351 is U-shaped and includes a connecting rod 3511 and two support rods 3512. The two support rods 3512 are connected to both ends of the connecting rod 3511. The connecting rod 3511 is provided with a first connecting portion 3513, which is connected to the base 10. Here, the connection between the first connecting portion 3513 and the base 10 is a rotatable connection. The free end of each support rod 3512 is provided with a second connecting portion 3514, which is connected to the second transmission member 352. Here, the second connecting portion 3514 and the second transmission member 352 are connected. The connection is a rotatable connection. Each support rod 3512 has a third connecting part 3515 at the end near the connecting rod 3511. The third connecting part 3515 is connected to the third transmission member 353. Here, the connection between the third connecting part 3515 and the third transmission member 353 is a rotatable connection. This realizes the connection between the first transmission member 351 and the second transmission member 352 and the third transmission member 353. The transmission member is connected through the two support rods 3512 of the first transmission member 351. This can increase the connection points of the transmission assembly, improve the reliability of the structure, and reduce the number of parts to a certain extent, which is convenient for manufacturing and assembly.

[0088] like Figure 5 and Figure 9 As shown, in some embodiments, the base 10 includes two opposing support frames 12, and the lead screw 33 is rotatably mounted on the support frame 12. The support frame 12 has a first mating part 121, which is rotatably connected to the first transmission component 351. By setting the support frame 12, the lead screw 33 and the transmission component 35 are respectively connected to the support frame 12, so that the components can be installed on the base 10. The installation is convenient and the assembly operation is easy.

[0089] Among them, such as Figure 9As shown, the support frame 12 may include a support plate, which has a guide rod hole 122 and a lead screw hole 123. The end of the lead screw 33 is located in the lead screw hole 123, and the end of the guide rod 11 is installed in the guide rod hole 122. The first mating part 121 may be located on the edge of the support plate, making the overall structure more compact.

[0090] like Figure 5 and Figure 10 As shown, in some embodiments, the base 10 has a shaft hole 131 and the display component 20 has a connecting shaft 211, or the base 10 has a connecting shaft 211 and the display component 20 has a shaft hole 131, with the connecting shaft 211 passing through the shaft hole 131, thereby making the display component 20 movably connected to the base 10.

[0091] like Figure 5 and Figure 10 As shown, in some examples, the base 10 includes a mounting base 13, and a shaft hole 131 is disposed on the mounting base 13. The shaft hole 131 is an elongated oval hole, wherein the extending direction of the shaft hole 311 is perpendicular to the extending direction of the connecting shaft 211. When the driving member 31 drives the two sliding members 34 to move closer to each other, it drives the middle part of the display component 20 to move forward. At this time, the connecting shaft 211 can rotate and slide inward within the shaft hole 131, so that the display component 20 forms a convex surface, that is, the display component 20 switches to an outward convex state. When the driving member 31 drives the two sliding members 34 to move away from each other, the middle part of the display component 20 moves backward. At this time, the connecting shaft 211 can rotate and slide outward within the shaft hole 131, so that the display component 20 forms a concave surface, that is, the display component 20 switches to an inward concave state.

[0092] Therefore, the connecting shaft 211 can slide relative to the shaft hole 311, which provides a certain degree of freedom. This ensures that the connecting shaft 211 is not restricted when the display component 20 is deformed, and thus the display component 20 can move with the drive mechanism. This reduces the interference between the connecting shaft 211 and the shaft hole 311, improves the rotational flexibility of the display component 20, and ensures that the connecting shaft 211 is always located in the shaft hole 311, thus guaranteeing the reliability of the connection between the display component 20 and the base 10.

[0093] like Figure 6 and Figure 7As shown, in some embodiments, the display device 100 further includes a detection device 50, which is disposed on the base 10. The display component 20 has a detection unit 23. The detection device 50 obtains the state of the display component 20 by detecting the information of the detection unit 23, including the deformation state of the display component (such as convex state, planar state, concave state). This allows the display device 100 to dynamically monitor its own state and may make self-adjustments based on this information. For example, the detection device 50 can ensure that the display component 20 is always kept in the required state, or make necessary adjustments when the state changes, thereby improving the reliability and performance of the display device 100. It can also predict and prevent potential problems by continuously monitoring the state of the display component 20, for fault diagnosis and preventive maintenance, etc.

[0094] like Figure 11 As shown, in some examples, the detection device 50 includes a plurality of photoelectric switches 51, which are spaced apart along the third direction F3. The detection unit 23 is a detection plate connected to the display component 20, which extends along the third direction F3 and moves with the switching of the state of the display component 20.

[0095] For example, there are three photoelectric switches 51, which correspond to the three limiting positions of the display component 20: concave, planar, and convex. The probe can extend into the location where the three photoelectric switches 51 are fixed. The shield moves synchronously with the deformation of the display component 20. When the shield moves to the position of the first photoelectric switch, the display component 20 is in the maximum concave state. When the shield moves between the first and second photoelectric switches, the curvature deformation of the concave shape can be adjusted. When the shield moves to the position of the second photoelectric switch, the display component is in the planar state. When the shield moves between the second and third photoelectric switches, the curvature deformation of the convex shape can be adjusted. When the shield moves to the position of the third photoelectric switch, the display component is in the maximum convex state.

[0096] Therefore, by using the shielding plate in conjunction with the photoelectric switch, the curvature of the display component can be arbitrarily adjusted between the maximum concave state and the maximum convex state.

[0097] like Figure 6As shown, in some examples, the base 10 is provided with a receiving cavity 101, which is located on one side of the drive mechanism 30 in the second direction F2. The detection device 50 is provided in the receiving cavity 101. The display component 20 is provided with a detection part 23 on the side near the drive mechanism 30. A part of the detection part 23 extends into the receiving cavity 101. The detection part 23 cooperates with the detection device 50, thereby hiding the detection device 50 inside the base 10, realizing the protection of electrical components. At the same time, when the detection part 23 moves with the display component 20, it can cooperate with the detection device 50, improving the compactness of the structure and helping to reduce the thickness of the entire display device 100.

[0098] like Figure 12 and Figure 13 As shown, in some embodiments, the display component 20 includes a display screen 201 and a support plate 202. The support plate 202 is disposed on the base 10 and is connected to the transmission component 35. The display screen 201 is disposed on the side of the support plate 202 away from the base 10. The support plate 202 serves to support the display screen 201, and the support plate 202 can also be bent and deformed. For example, the support plate 202 can be a thin metal plate or a plastic plate, etc. The display screen 201 can be glued to the support plate 202.

[0099] The support plate 202 is connected to the transmission assembly 35. The support plate 202 is provided with a first connector 21 and a second connector 22. The first connector 21 and the second connector 22 are installed on the side of the support plate 202 away from the display screen 201. There are two first connectors 21, which are arranged at intervals along the first direction F1. The second connector 21 is located between the two first connectors 21. The second connector 22 is connected to the transmission assembly 35. The first connector 21 is connected to the base 10 through a rotating shaft 211 to fix the display assembly 20 on the base 10.

[0100] The display screen 201 may include a flexible screen and a cover plate. The flexible screen is used to display image information and can deform under external force. The cover plate is used to protect the display surface of the flexible screen and may be made of glass or other materials with high light transmittance. The support plate 202 may be made of a flexible material, so that the support plate 202 can deform together with the display screen 201.

[0101] like Figure 13As shown, in some embodiments, the display component 20 further includes a back plate 203, which is disposed on the side of the support plate 202 near the base 10. The support plate 202 and the base 10 are connected by a first connector 21, and the support plate 202 and the transmission component 35 are connected by a second connector 22. The back plate 203 is provided with a through hole 2031. The first connector 21 is disposed on the support plate 202, and at least a portion of the first connector 21 passes through the corresponding through hole 2031 to cooperate with the base 10. The second connector 22 is disposed on the support plate 202, and a portion of the second connector 22 passes through the corresponding through hole 2031 to connect with the transmission component 35.

[0102] The back plate 203 serves to support and protect the display screen 201 and the support plate 202. The back plate 203 may be made of a deformable material, including but not limited to silicone, thermoplastic polyurethanes (TPU), and polyurethane (PU).

[0103] As shown in the figure, in some embodiments, the display device 100 further includes a housing 40, which has a housing body 41 and a frame 42. The housing body 41 is located on the side of the base 10 away from the display component 20 and covers the drive mechanism 30. The housing body 41 can also cover the back of the display component 20, thereby protecting the entire drive mechanism 30 and the display component 20. The frame 42 is located on the side of the housing body 41 close to the display component 20 and extends circumferentially along the display component 20, thereby also protecting the display component 20.

[0104] Among them, such as Figure 1 As shown, when the display component 20 is in the convex state, the outer periphery of the display component 20 matches the frame 42, with only a small gap between them, thereby improving the aesthetics of the appearance. Of course, the outer periphery of the display component 20 can also match the frame 42 when the display component 20 is in the flat or concave state. That is, the shape of the frame 42 can be designed according to a more commonly used state of the display component 20, so that the overall appearance of the display component 20 is more beautiful when it is in this state. It can also prevent external debris and dust from falling into the drive mechanism 30, affecting the movement of the slider 34, the activity or deformation of the transmission component 35, and thus affecting the service life of the display device 100 and the user experience.

[0105] The vehicle-mounted device 1000 according to an embodiment of the present invention includes a display device 100 according to an embodiment of the present invention. Thus, the vehicle-mounted device 1000 can change the radius of curvature of the display component 20 according to different scenarios. The display component 20 can be applied to a wide range of scenarios, improving the user's sensory comfort and user experience. Moreover, the structure is simple, which can reduce manufacturing costs. The mechanical structure is more reliable. The display device 100 occupies little thickness space, which is convenient for installation.

[0106] The vehicle 10000 according to an embodiment of the present invention includes an in-vehicle device 1000 according to an embodiment of the present invention.

Moreover, the structure is simple, which can reduce manufacturing costs. The mechanical structure is more reliable. The display device 100 occupies little thickness space, which is convenient for installation.

[0107] The display device 100 can be used for multimedia display on the center console, instrument display, and armrest display in vehicle 10000. By inputting commands to the display device 100, the radius of curvature of the display component 20 can be changed to adapt to the user's needs in different scenarios. For example, the user can send signals to the display device 100 via voice control, gesture control, touch button control, screen touch control, or other switches, thereby enabling the drive mechanism 30 of the display device 100 to deform the display component 20, so that the display component 20 is in a planar state relative to the base 10. Figure 2 As shown), concave state ( Figure 3 (as shown) or in an outward convex state ( Figure 1 As shown, by changing the radius of curvature of the display component 20, the technological feel of the vehicle 10000 can be enhanced, the sensory comfort of the user can be improved, and the user experience can be better.
