[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] In the description of the embodiments of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings. The term "connection" in this application, unless otherwise specified, mainly refers to a physical structural connection, and may also include meanings such as direct connection or indirect connection when specified. The terms "first" and "second" in the specification and claims of this application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the term "includes" and any variations thereof are intended to cover non-exclusive inclusions.

[0036] See also Figure 1-Figure 3 , Figure 1 is a schematic block diagram of a car 100 in an embodiment of the present application, Figure 2 is a schematic diagram of the three-dimensional structure of the instrument panel 300 and the display device 200 in the embodiment of the present application, Figure 3 for Figure 2 The cross-sectional schematic diagram of the flexible display screen 22 in the figure is unfolded on the dashboard 300 at the AA position. The automobile 100 comprises a display device 200, a dashboard 300 and a controller 4, wherein the dashboard 300 is located at the front end of the cab of the automobile 100, the display device 200 is located at the back of the dashboard 300, the display device 200 comprises a rolled flexible display screen 22, the dashboard 300 is used to support the unfolded flexible display screen 22 after unrolling, and the controller 4 is used to control the working state of the display device 200.

[0037] Thus, the dashboard 300 supports the flexible display screen 22 that is unfolded after being unrolled, thereby improving the stability and reliability of the flexible display screen 22 during use and better realizing the touch screen operation of the flexible display screen 22. The user can control the display device 200 through the controller 4 to meet driving needs, making the display device 200 more intelligent and improving the user's driving experience.

[0038] In some embodiments, the flexible display screen 22 can output control instructions according to the user's touch screen operation to control the working status of the internal functional devices of the car 100, so the dashboard 300 is used to support the flexible display screen 22 that is unfolded after unrolling to facilitate touch screen operation.

[0039] Please also read Figure 4-Figure 7 , Figure 4 for Figure 3 The enlarged view at B, Figure 5 for Figure 2 A schematic diagram of the back of the instrument panel 300 in FIG. Figure 6 for Figure 2 A schematic diagram of the back of the flexible display screen 22 after it is unfolded, Figure 7 2 is a three-dimensional schematic diagram of a display device 200 in an embodiment of the present application. In some embodiments, the automobile 100 further includes a magnetic member 5, which is disposed at the bottom of the instrument panel 300, and is used to magnetically absorb the fixing member 29 to magnetically fix the flexible display screen 22 on the instrument panel 300.

[0040] Therefore, after the flexible display screen 22 is unfolded, the flexible display screen 22 is fixed on the dashboard 300 by magnetic adsorption, which ensures the fixation reliability of the flexible display screen 22, improves the stability and reliability of the flexible display screen 22 during use, and is more suitable for the operating conditions of the automobile 100.

[0041] In some embodiments, the magnetic attraction member 5 is a magnet, and the magnet is used to generate magnetic force after being energized. The controller 4 is also used to control the energization and de-energization of the magnet to control the generation of magnetic force.

[0042] Thus, the magnet can be used as a magnetic switch to control the generation of magnetic force according to whether it is powered on, so as to cut off the power when magnetic adsorption is not needed to prevent the generation of magnetic force, thereby saving energy and facilitating other operations for users; and, through the controller 4, the power on and off of the magnet can be controlled according to user needs to control the length of the flexible display screen 22 fixed on the dashboard 300, so that the user can adjust the range of the flexible display screen 22 used according to needs.

[0043] In some embodiments, the controller 4 controls the magnetic attraction of the fixing member 29 to the magnetic attraction member 5 , and the magnetic attraction member 5 is made of common magnetic materials, such as magnets, iron alloys, etc.

[0044] In some other embodiments, the controller 4 controls the magnetic attraction of the magnetic attraction member 5 to the fixing member 29, and the fixing member 29 is made of common magnetic materials, such as magnets, iron alloys, etc.

[0045] In some other embodiments, the controller 4 can control the magnetic attraction of the fixing member 29 and the magnetic attraction member 5 at the same time.

[0046] Please also read Figure 8-Figure 10 , Figure 8 for Figure 7 An exploded view of the display device 200 in FIG. Fig. 9 for Figure 7 A cross-sectional perspective diagram of some components of the lifting mechanism 3 combined base 1 at CC, Fig.10 for Figure 7 The display device 200 comprises a base 1, a display mechanism 2 and a fixing member 29. The display mechanism 2 comprises a rotating shaft 21 and a flexible display screen 22. The flexible display screen 22 is wound on the rotating shaft 21. The rotating shaft 21 can be rotated to wind or unwind the flexible display screen 22. The fixing member 29 is connected to the flexible display screen 22 and is used to fix the flexible display screen 22 at a predetermined position.

[0047] Thus, the display device 200 can curl up the flexible display screen 22 when it is not in use to reduce the occupied space area, and the unfolded flexible display screen 22 can be fixed at a predetermined position by the fixing member 29. The setting of the fixing member 29 improves the support reliability of the flexible display screen 22 during touch screen operation, so that the user can more accurately perform touch screen operation on the flexible display screen 22 as needed, making the touch screen operation of the flexible display screen 22 more convenient, and also improving the practicality of the display device 200 and the safety during use.

[0048] It can be understood that the fixing part 29 can be a component such as a buckle to mechanically fix the flexible display screen 22 at a predetermined position. The fixing part 29 can also be a component such as a magnetic part with magnetic force to magnetically fix the flexible display screen 22 at a predetermined position. The specific implementation scheme of the present application selects a component that can generate magnetism to magnetically fix the flexible display screen 22 at a predetermined position.

[0049] In some embodiments, the fixing member 29 is a magnetic strip, and the magnetic strip is used to fix the flexible display screen 22 at a predetermined position by magnetic force after the flexible display screen 22 is unfolded.

[0050] Therefore, the fixing member 29 can fix the flexible display screen 22 at a predetermined position by generating magnetic force, thereby reducing production costs, simplifying the structure and making the control simpler, and improving the user experience.

[0051] In some embodiments, the fixing member 29 is disposed around the edge of the flexible display screen 22 .

[0052] Therefore, the fixing member 29 is arranged around the edge of the flexible display screen 22 so that the edge of the flexible display screen 22 can be fixed at a predetermined position, thereby improving the fixing reliability of the flexible display screen 22 .

[0053] It is understandable that the position where the fixing member 29 is connected to the flexible display screen 22 can be selected according to actual needs. When the fixing member 29 is a magnetic strip, it can also be set around the edge of the flexible display screen 22 for multiple weeks, which is not limited here.

[0054] In some embodiments, Figure 5 and Figure 6 As shown, the magnetic attraction member 5 is disposed at a position corresponding to the fixing member 29 to fix the flexible display screen 22 at a predetermined position of the dashboard 300 with better magnetic force.

[0055] In some embodiments, the display device 200 further includes a lifting mechanism 3 , wherein the lifting mechanism 3 is connected between the base 1 and the display mechanism 2 , and the lifting mechanism 3 is lifted and lowered to drive the display mechanism 2 to lift and lower.

[0056] Thus, the display device 200 can raise and lower the display mechanism 2 through the lifting mechanism 3 according to actual driving needs. When the flexible display screen 22 is needed, it is raised and unfolded for easy use. When the flexible display screen 22 is not needed, it is rolled up and lowered to hide the display mechanism 2 and reduce the occupied space area, which greatly improves the utilization rate of the cab space and greatly enhances the user's driving experience.

[0057] In some embodiments, the dashboard 300 is provided with a display opening 6, and the display device 200 is located at a position of the display opening 6 close to the back of the dashboard 300. When the display mechanism 2 rises, it is exposed from the display opening 6, and the display mechanism 2 unrolls and unfolds the flexible display screen 22 on the dashboard 300. When the display mechanism 2 descends, it sinks from the display opening 6 and is hidden at the back of the dashboard 300.

[0058] In some embodiments, the display opening 6 can also be covered or opened by a cover.

[0059] In some embodiments, the controller 4 can control the lifting mechanism 3 to lift and lower to drive the display mechanism 2 to lift and lower.

[0060] In some embodiments, the lifting mechanism 3 includes a driving member 31, a lifting assembly 32 and a lifting plate 33, the driving member 31 is installed on the base 1, the lifting assembly 32 is connected between the driving member 31 and one side of the lifting plate 33, the display mechanism 2 is installed on the other side of the lifting plate 33, and the driving member 31 drives the lifting plate 33 to rise and fall through the lifting assembly 32.

[0061] Thus, the driving member 31 drives the lifting assembly 32 to make the lifting plate 33 perform lifting movement, and the display mechanism 2 also rises and falls accordingly, so that the display mechanism 2 can be hidden and used as needed, and can be lowered and hidden to the back of the dashboard 300 to reduce the size of the space occupied by the cab, thereby greatly improving the utilization rate of the cab space and greatly improving the user's driving experience.

[0062] The size of the flexible display screen 22 can be designed as needed. Since the flexible display screen 22 can be rolled up and lowered to be hidden, enlarging the flexible display screen 22 will not cause the cab space of the car 100 to be too crowded, thereby improving the driving experience.

[0063] In some embodiments, the driving member 31 drives the lifting assembly 32 to move along the first direction 11 so that the lifting plate 33 performs a lifting movement along the second direction 12 , wherein the first direction 11 is a horizontal direction and the second direction 12 is a height direction.

[0064] Thus, the driving member 31 can drive the lifting plate 33 to move up and down through the lifting assembly 32. The driving member 31 drives the lifting assembly 32 to move along the first direction 11, which can reduce the overall size of the display device 200 in the second direction 12, thereby improving the applicability of the display device 200.

[0065] In some other embodiments, the driving member 31 drives the lifting assembly 32 to move along the second direction 12 so that the lifting plate 33 performs a lifting movement along the second direction 12 .

[0066] Therefore, the driving member 31 and the lifting plate 33 move in the same direction, so that the design of the lifting mechanism 3 is more diversified, which is convenient for application in various environments and improves the applicability of the display device 200.

[0067] In some embodiments, the lifting assembly 32 includes a first connecting rod 321 and a second connecting rod 322, the first connecting rod 321 and the second connecting rod 322 are rotatably cross-connected, the top end of the first connecting rod 321 is rotatably connected to the lifting plate 33, the top end of the second connecting rod 322 is movably connected to the lifting plate 33, the bottom end of the second connecting rod 322 is fixed to the base 1, the bottom end of the first connecting rod 321 is connected to the driving member 31, and the driving member 31 drives the bottom end of the first connecting rod 321 to move along the first direction 11 to change the lifting height of the lifting plate 33 in the second direction 12.

[0068] The lifting and lowering operation of the lifting assembly 32 driven by the driving member 31 is completed by the first connecting rod 321 and the second connecting rod 322. The first connecting rod 321 and the second connecting rod 322 are rotatably cross-connected so that they are fixed at one point and rotated to change the height of the first connecting rod 321 and the second connecting rod 322 in the second direction 12. The bottom of the second connecting rod 322 is fixed, and the top end of the first connecting rod 321 is rotated by moving the bottom end of the first connecting rod 321. The top end of the second connecting rod 322 and the bottom end of the first connecting rod 321 are driven to move in the same direction along the first direction 11 due to the relative movement of the first connecting rod 321 and the second connecting rod 322, so that the lifting plate 33 is stably lifted and lowered in the second direction 12. This design makes the lifting assembly 32 simple in structure, the lifting and lowering movement of the lifting mechanism 3 is smooth and the structure is stable, and the control of the lifting and lowering movement becomes simple and accurate, which improves the transmission accuracy and reduces the production cost.

[0069] In some embodiments, the first connecting rod 321 and the second connecting rod 322 are rotatably cross-connected via the connecting rod pin 326 .

[0070] It can be understood that the top end of the first connecting rod 321 can be rotatably connected to the lifting plate 33 through the connecting rod pin 326. The connection method can be selected according to actual needs, as long as it is ensured that the top end of the first connecting rod 321 can be used as a rotatable fulcrum and rotated around the top end of the first connecting rod 321. The first connecting rod 321 and the second connecting rod 322 can also be rotatably cross-connected through the connecting rod pin 326 axis, which is not limited here.

[0071] In some embodiments, the lifting assembly 32 also includes a first shaft 323 and a second shaft 324, and there are two first connecting rods 321 and two second connecting rods 322 respectively, each of the first connecting rods 321 is rotatably cross-connected with one second connecting rod 322, the first shaft 323 is connected to the bottom ends of the two first connecting rods 321, the second shaft 324 is connected to the bottom ends of the two second connecting rods 322, and the driving member 31 is connected to the first shaft 323.

[0072] Thus, the two second connecting rods 322 are connected by the first shaft 323 so that the driving member 31 can jointly control their movement. The driving member 31 drives the first shaft 323 to move along the first direction 11 to drive the bottom ends of the two first connecting rods 321 to move, so that the lifting plate 33 can be lifted and lowered smoothly in the second direction 12. This design can make the lifting assembly 32 simple in structure, the lifting movement of the lifting mechanism 3 is smooth and reliable, and the control is simple, which also reduces the production cost.

[0073] It can be understood that the number of the first connecting rod 321 and the second connecting rod 322 can be selected according to actual needs, and the first shaft 323 and the second shaft 324 can be but are not limited to connecting rod pins, which are not limited here.

[0074] In some embodiments, the base 1 includes a bottom plate 15 and a first side plate 16, the first side plate 16 is arranged on one side of the bottom plate 15, the first side plate 16 is provided with a first guide portion 17 along the first direction 11, and the end of the first axis 323 cooperates with the first guide portion 17 to guide the movement of the first axis 323 along the first direction 11.

[0075] Thus, the first side plate 16 is provided with the first guide portion 17, and under the drive of the driving member 31, the first guide portion 17 can enable the end of the first shaft 323 to move along the first direction 11 on the first side plate 16. The first guide portion 17 is set to a certain length to limit the moving distance of the first shaft 323 so that the lifting plate 33 stops lifting after reaching a certain height. This design can realize mechanical limiting to control the lifting height of the lifting mechanism 3, and the control is simple.

[0076] In some embodiments, the base 1 includes two first side panels 16, which are relatively arranged on both sides of the bottom plate 15, and each of the first side panels 16 is provided with the first guide portion 17 along the first direction 11, and the two ends of the first axis 323 respectively cooperate with the two first guide portions 17 to guide the movement of the first axis 323 along the first direction 11.

[0077] It is understandable that the number of the first side panels 16 can be set according to actual needs and is not limited here.

[0078] In some embodiments, the first guide portion 17 is disposed on the inner side of the first side panel 16, and the first guide portion 17 is a guide groove, in which a guide rail is installed along the first direction 11, and a roller 327 is installed at the end of the first shaft 323 so that the end of the first shaft 323 moves along the first direction 11 on the guide rail under the action of the roller 327, wherein the roller 327 is interference fit with the end of the first shaft 323.

[0079] In some other embodiments, the first guide portion 17 is arranged on the inner side of the first side panel 16, and the first guide portion 17 is a guide hole, a guide rail is installed in the guide hole along the first direction 11, and a roller 327 is installed at the end of the first shaft 323 so that the end of the first shaft 323 moves along the first direction 11 on the guide rail under the action of the roller 327.

[0080] In some other embodiments, the first guide portion 17 is disposed on the first side plate 16, the first guide portion 17 is a guide rail, and a roller 327 is installed at the end of the first shaft 323 so that the end of the first shaft 323 moves along the first direction 11 on the guide rail under the action of the roller 327.

[0081] It is understandable that the position and style of the first guide portion 17 can be selected according to actual needs, and a slider or the like can be installed at the end of the first shaft 323. The guide rail can be, but is not limited to, a waist-shaped guide rail, which is not limited here.

[0082] In some embodiments, the base further includes a third side plate 18 , and the third side plate 18 is connected between the first side plate 16 and the bottom plate 15 .

[0083] In some embodiments, the lifting assembly 32 also includes a third shaft 325, which is connected between the top end of the second connecting rod 322 and the lifting plate 33, and the lifting plate 33 includes a connecting plate 331 and a second side plate 332, wherein the second side plate 332 is arranged on one side of the connecting plate 331, and a second guide portion 333 is provided on the second side plate 332 along the first direction 11, and the end of the third shaft 325 cooperates with the second guide portion 333 to guide the movement of the third shaft 325 along the first direction 11.

[0084] Thus, the top end of the second connecting rod 322 cooperates with the second guide portion 333 through the third shaft 325 to move along the first direction 11, so that the second connecting rod 322 cooperates with the movement of the first connecting rod 321, so that the top end of the second connecting rod 322 moves in the same direction as the bottom end of the first connecting rod 321, so that the lifting plate 33 can be lifted and lowered smoothly, and the second guide portion 333 will also limit the moving distance of the top end of the second connecting rod 322 to cooperate with the first connecting rod 321 to lift the lifting plate 33 to a certain height position along the second direction 12.

[0085] In some embodiments, the lifting plate 33 includes two second side plates 332, and the two second side plates 332 are relatively arranged on both sides of the connecting plate 331, and each second side plate 332 is provided with a second guide portion 333 along the first direction 11, and the two ends of the third shaft 325 respectively cooperate with the two second guide portions 333 to guide the movement of the third shaft 325 along the first direction 11.

[0086] It can be understood that the number of the second side panels 332 can be set according to actual needs and is not limited here.

[0087] In some other embodiments, there are two first connecting rods 321 and two second connecting rods 322 respectively, each of the first connecting rods 321 is rotatably cross-connected with one second connecting rod 322, the third shaft 325 connects the top ends of the two second connecting rods 322 and the end of the third shaft 325 cooperates with the second guide portion 333.

[0088] As described above, the position and style of the second guide portion 333 can be selected according to actual needs, and a slider or the like can be installed at the end of the third shaft 325, which is not limited here.

[0089] It can be understood that the third shaft 325 can be but is not limited to a connecting rod pin shaft, which is not limited here.

[0090] Please join us Fig.11 and Fig.12 , Fig.11 is a three-dimensional schematic diagram of a display device 200 in another embodiment of the present application. Fig.12 3D is a schematic diagram of a display device 200 in another embodiment of the present application. In some embodiments, the driving member 31 includes a driving end 311 and a fixed end 312, the driving end 311 is connected to the bottom end of the first connecting rod 321, the fixed end 312 is connected to the bottom end of the second connecting rod 322, and the driving end 311 drives the bottom end of the first connecting rod 321 to move along the first direction 11 to change the lifting height of the lifting plate 33 in the second direction 12.

[0091] Thus, the driving member 31 enables the bottom end of the first connecting rod 321 to move along the first direction 11 through the cooperation of the driving end 311 and the fixed end 312. The fixed end 312 cannot move because it is fixedly connected to the bottom end of the second connecting rod 322. The driving end 311 is stably moved along the first direction 11 through the fixing effect of the fixed end 312. This design simplifies the structure of the driving member 31, reduces production costs, and is easy to control.

[0092] In some embodiments, the controller 4 controls the driving end 311 to move along the first direction 11 .

[0093] In some embodiments, the driving member 31 is a hydraulic cylinder, the driving end 311 is a hydraulic cylinder body, and the fixed end 312 is a piston rod, which is inserted into the hydraulic cylinder body. The hydraulic cylinder body moves along the first direction 11 under the drive of the controller 4. When the flexible display screen 22 is needed, the hydraulic cylinder body moves along the first direction 11 close to the bottom end of the second connecting rod 322 to raise the display mechanism 2. When the flexible display screen 22 is not needed, the hydraulic cylinder body moves along the first direction 11 away from the bottom end of the second connecting rod 322 to descend and hide the display mechanism 2. The hydraulic cylinder moves smoothly and reliably, and no noise is generated during the movement.

[0094] It is understandable that the driving member 31 may be but not limited to a hydraulic cylinder, the driving end 311 may be but not limited to a hydraulic cylinder body, and the fixed end 312 may be but not limited to a piston rod, which is not limited here.

[0095] In combination with the above embodiment, the driving end 311 can also be connected to the first shaft 323, and the fixed end 312 is connected to the second shaft 324. The driving end 311 drives the end of the first shaft 323 to cooperate with the first guide portion 17 so that the first shaft 323 moves along the first direction 11, thereby driving the bottom end of the first connecting rod 321 to move along the first direction 11.

[0096] In some embodiments, the driving member 31 includes a motor 313, a gear 314 and a rack 315. The motor 313 is fixedly mounted on the base 1. The output shaft of the motor 313 is connected to the gear 314. The gear 314 is meshed with the rack 315. One end of the rack 315 is connected to the bottom end of the first connecting rod 321. The output shaft drives the gear 314 to rotate. During the rotation, the gear 314 drives the rack 315 to move along the first direction 11. The rack 315 drives the bottom end of the first connecting rod 321 to move along the first direction 11 to change the lifting height of the lifting plate 33 in the second direction 12.

[0097] Thus, since the motor 313 drives the gear 314 to rotate fixedly around the output shaft, the relative movement of the gear 314 and the rack 315 causes the rack 315 to move along the first direction 11 to drive the bottom end of the first connecting rod 321 to move along the first direction 11. This design simplifies the structure of the driving member 31, reduces production costs, and is easy to control.

[0098] In combination with the above embodiment, the rack 315 can also be connected to the first shaft 323, and the rack 315 drives the end of the first shaft 323 to cooperate with the first guide portion 17 so that the first shaft 323 moves along the first direction 11, thereby driving the bottom end of the first connecting rod 321 to move along the first direction 11.

[0099] In some embodiments, the controller 4 controls the direction of rotation of the output shaft of the motor 313 to adjust the movement of the rack 315 along the first direction 11. If the output shaft rotates along the first direction 11 away from the bottom end of the second connecting rod 322, the rack 315 moves along the first direction 11 to approach the bottom end of the second connecting rod 322. If the output shaft rotates along the first direction 11 toward the bottom end of the second connecting rod 322, the rack 315 moves along the first direction 11 away from the bottom end of the second connecting rod 322.

[0100] In some embodiments, the driving member 31 includes a motor 313, a screw rod 316, a nut (not shown in the figure) and a connecting member 317, wherein the connecting member 317 is connected to the bottom end of the first connecting rod 321, and the nut is installed in the connecting member 317. The motor 313 is fixedly installed on the base 1, one end of the screw rod 316 is inserted into the motor 313, and the other end of the screw rod 316 passes through the nut and is connected to the bottom end of the second connecting rod 322. The motor 313 drives the screw rod 316 to rotate so as to move relative to the nut and drive the connecting member 317 to move along the first direction 11. The connecting member 317 drives the bottom end of the first connecting rod 321 to move along the first direction 11 to change the lifting height of the lifting plate 33 in the second direction 12.

[0101] Thus, since the motor 313 drives the screw rod 316 to rotate at a fixed position, the relative movement of the screw rod 316 and the nut causes the connecting member 317 to move along the first direction 11 to drive the bottom end of the first connecting rod 321 to move along the first direction 11. This design simplifies the structure of the driving member 31, reduces production costs, and is easy to control.

[0102] In combination with the above embodiment, there may be two connecting members 317, one connecting member 317 is connected to the first shaft 323, the other end of the screw rod 316 is inserted into the other connecting member 317 and connected to the second shaft 324, and the connecting member 317 drives the end of the first shaft 323 to cooperate with the first guide portion 17 under the action of the relative movement of the screw rod 316 and the nut so that the first shaft 323 moves along the first direction 11, thereby driving the bottom end of the first connecting rod 321 to move along the first direction 11.

[0103] In some embodiments, the controller 4 controls the rotation direction of the screw rod 316 through the motor 313 to adjust the movement of the connecting member 317 along the first direction 11. If the screw rod 316 rotates along the third direction 13 perpendicular to the first direction 11, the connecting member 317 moves along the first direction 11 to approach the bottom end of the second connecting rod 322. If the screw rod 316 rotates along the fourth direction 14 perpendicular to the first direction 11, the connecting member 317 moves along the first direction 11 to move away from the bottom end of the second connecting rod 322. The width direction of the base 1 is defined as the third direction 13 and the fourth direction 14. The third direction 13 and the fourth direction 14 are arranged relative to each other, that is, opposite directions.

[0104] It is understandable that the style of the driving member 31 and the setting of the relative movement within the driving member 31 can be selected according to actual needs and are not limited here.

[0105] In some embodiments, the display mechanism 2 also includes a rotating driving member 23, the rotating shaft 21 is inserted into the rotating driving member 23 to connect the rotating driving member 23, the flexible display screen 22 is wound and connected to the rotating shaft 21, and the rotating driving member 23 drives the rotating shaft 21 to rotate to wind or unwind the flexible display screen 22.

[0106] Thus, the display device 200 can roll or unroll the flexible display screen 22 while realizing automatic lifting, thereby improving the intelligence of the display device 200; and the rotating drive member 23 makes it more convenient to unroll and roll the flexible display screen 22, thereby better realizing the interconnection between the display device 200 and the automobile 100 and improving the transmission accuracy.

[0107] It is understandable that the rotating driving member 23 may be, but is not limited to, a motor 313, and may be selected according to actual needs and is not limited here.

[0108] In some embodiments, an internal spline is provided inside the rotary drive member 23, and an external spline is provided at the end of the rotating shaft 21, and the rotary drive member 23 and the rotating shaft 21 are connected via the spline.

[0109] It is understandable that the rotary drive member 23 and the rotating shaft 21 can be matched through, but not limited to, a spline, and can be configured according to actual needs, which is not limited here.

[0110] When the flexible display screen 22 is needed, the lifting mechanism 3 raises the display mechanism 2, and the rotating drive member 23 drives the rotating shaft 21 to rotate along the third direction 13 to unwind and unfold the flexible display screen 22; when the flexible display screen 22 is not needed, the rotating drive member 23 drives the rotating shaft 21 to rotate along the fourth direction 14 to roll up and curl the flexible display screen 22 around the rotating shaft 21, and the lifting mechanism 3 descends to hide the display mechanism 2.

[0111] In some embodiments, the controller 4 may control the rotation driving member 23 to drive the rotating shaft 21 to rotate, so as to automatically roll up or unroll the flexible display screen 22 according to user needs.

[0112] In some embodiments, the rotating drive member 23 drives the rotating shaft 21 to rotate and drive the flexible display screen 22 to unwind. During the rotation of the rotating shaft 21, the fixing member 29 does not generate magnetic force, that is, the magnetic adsorption function is not turned on. When the flexible display screen 22 is unrolled and unfolded to a fixed position, the rotating drive member 23 stops working. At this time, the fixing member 29 generates magnetic force, that is, the magnetic adsorption function is turned on to magnetically adsorb the magnetic suction member 5. The flexible display screen 22 is fixed on the dashboard 300 because the fixing member 29 and the magnetic suction member 5 are adsorbed together.

[0113] It can be understood that the movement of the lifting mechanism 3 and the display mechanism 2 can also be applied to other compound movements, which is not limited here.

[0114] In some embodiments, the display mechanism 2 also includes a protective shell 27, and the rotating drive member 23 is installed inside the protective shell 27 to protect the rotating drive member 23, and the protective shell 27 and the rotating drive member 23 are fixedly connected by screws 28, wherein the screws 28 can be four hexagon socket screws, which are not limited here.

[0115] In some embodiments, the display mechanism 2 also includes a shell 24 and a bearing 25. The shell 24 is installed on the lifting plate 33. The shell 24 forms a receiving space 241, a reeling port 242, and a bearing port 243. The rotating shaft 21 is located in the receiving space 241. The bearing 25 is installed in the bearing port 243. The end of the rotating shaft 21 extends through the bearing 25 to connect to the rotating drive member 23. The flexible display screen 22 is accommodated in the receiving space 241 and wound on the rotating shaft 21. One end of the flexible display screen 22 extends out of the shell 24 through the reeling port 242.

[0116] Therefore, the setting of the shell 24 can protect the flexible display screen 22 after being rolled up and avoid damage; and the bearing 25 supports the rotating shaft 21 in the accommodating space 241 to fix it axially and radially, so that it can stably unwind and wind the flexible display screen 22 in a fixed position, thereby enhancing the stability of the operation of the display mechanism 2.

[0117] It is understandable that the bottom of the housing 24 may be but is not limited to being welded and fixed to the connecting plate 331 , which is not limited here.

[0118] When the end of the flexible display screen 22 is in contact with the unwinding port during winding, the controller 4 controls the rotary drive member 23 to stop working, the rotating shaft 21 stops rotating, and the flexible display screen 22 finishes winding.

[0119] In some embodiments, a limiting member 26 may be installed on the rotating shaft 21 between the bearing 25 and the flexible display screen 22 to limit and fix the bearing 25 and the flexible display screen 22 .

[0120] It is understandable that the limiting member 26 may be, but is not limited to, a retaining spring, and may be selected according to actual needs and is not limited here.
