Description

Technical Field

[0001] This invention relates to the field of automotive technology, specifically providing a seat display device and a vehicle. Background Technology

[0002] Currently, there are several solutions for car seatback displays. The first is a floating design, whether a fixed structure or a temporary connector, which is quite intrusive to the interior and requires sufficient rear legroom to avoid obstructing passenger entry and exit. The second is an embedded design, such as the screen directly embedded in the seatback or using an optical curved mirror for magnification. This solution is integrated into the seatback, occupying significant space, and the constant presence of the display poses a safety hazard. Furthermore, it lacks angle adjustment; the screen changes angle with the seatback, affecting the viewing angle and overall passenger experience. None of these solutions offer the experience of a large-size display.

[0003] Therefore, the present invention needs to provide a new seat display device and vehicle to solve the above-mentioned technical problems. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problems that existing car seat back display screens are too intrusive to the interior, occupy a lot of space in the rear seats and seat backs, and cannot be adjusted according to the angle of the seat back, thus affecting the viewing angle and thus affecting the passenger experience.

[0005] To this end, in a first aspect, the present invention provides a seat display device, the seat display device comprising a flexible display module and a first angle adjustment mechanism, both the flexible display module and the first angle adjustment mechanism being disposed inside the seat back, the flexible display module comprising a flexible display, the back of the seat back being provided with an inlet / outlet for extending the flexible display to the outside of the seat back or retracting it into the seat back, and the first angle adjustment mechanism being configured to adjust the tilt angle of the flexible display relative to the seat back to adapt to different reclining angles of the seat back.

[0006] With the above technical solution, the flexible display screen designed in this invention can be pulled out when in use and hidden in the seat back when not in use, so as not to cause intrusion into the interior space of the vehicle and reduce space occupation. Moreover, the first angle adjustment mechanism can adjust the tilt angle of the flexible display screen relative to the seat back, so that passengers have a better viewing experience when the seat back is reclined at different angles and when the passenger sits in different positions.

[0007] In a specific embodiment of the above-mentioned seat display device, the flexible display module further includes a support member and a scroll. The support member is rotatably connected inside the seat back, and the scroll is rotatably connected to the support member. The scroll is configured to automatically wind up the flexible display.

[0008] In a specific embodiment of the above-mentioned seat display device, the first angle adjustment mechanism includes a motor and a gear assembly. The motor is fixed inside the seat back and drives the support member to rotate through the gear assembly.

[0009] In a specific embodiment of the above-mentioned seat display device, the seat display device further includes a damping mechanism, which is configured to generate different amounts of pressure on the flexible display screen to limit the extension and retraction speed of the flexible display screen with different forces.

[0010] With the above technical solution, the damping mechanism designed in this invention can apply pressure to the flexible display screen, so that the flexible display screen will not roll back too quickly during automatic rewinding, thus improving safety. It can also press the flexible display screen into a suspended state at any position, making it more convenient to use.

[0011] In a specific embodiment of the aforementioned seat display device, the damping mechanism is disposed on the support member. The damping mechanism includes two pressure columns and an elastic member. The two pressure columns are disposed on the support member, and at least one pressure column is connected to the support member through the elastic member. The flexible display screen passes between the two pressure columns. At least one pressure column is made of an electromagnet. When energized, the two pressure columns repel each other to allow the flexible display screen to extend and retract. When de-energized, the two pressure columns press the flexible display screen together under the action of the elastic member to stop it from extending and retracting.

[0012] With the above technical solution, the flexible display screen passes between the two pressure columns. When the power is off, the elastic force of the elastic element causes the two pressure columns to clamp the flexible display screen, allowing it to hover at any position. When the power is on, the two pressure columns repel each other, allowing the flexible display screen to pass between them. By controlling the gap between the two pressure columns, the pressure on the flexible display screen can be adjusted, thus achieving both slow retraction and hovering. The operation is simple and convenient, and the manufacturing cost is low.

[0013] In a specific embodiment of the above-mentioned seat display device, the seat display device further includes a telescopic mechanism located on the back side of the flexible display screen inside the seat back. The telescopic mechanism can extend and retract with the flexible display screen to provide back support for the extended flexible display screen.

[0014] With the above technical solution, the present invention provides a telescopic mechanism on the back side of the flexible display screen. The telescopic mechanism can extend and retract with the flexible display screen, providing stable back support after the flexible display screen is extended and unfolded. It has good stability and is conducive to improving the user experience.

[0015] In a specific embodiment of the above-mentioned seat display device, the telescopic mechanism is a telescopic grille structure. The first end of the telescopic mechanism is fixedly connected to the first end of the flexible display screen, and the second end of the telescopic mechanism is fixed with a stop mechanism to limit the movement position of the second end of the telescopic mechanism so that the telescopic mechanism can automatically follow the flexible display screen to extend and retract.

[0016] In a specific embodiment of the above-mentioned seat display device, a first connector is fixed to the first end of the flexible display screen, and a second connector is provided on the back of the seat back. The first connector and the second connector are detachably connected to limit the length of the flexible display screen extending to the outside of the seat back. The size of the first connector is larger than the size of the inlet and outlet.

[0017] When the above technical solution is adopted, the detachable connection between the first connector and the second connector can fix or loosen the extended flexible display screen, making it easy to use and hide.

[0018] In a specific embodiment of the above-mentioned seat display device, a second angle adjustment mechanism is also provided inside the seat back. The inlet and outlet and the second connector are both connected to a second angle adjustment mechanism. The second angle adjustment mechanism is configured to adjust the tilt angle of the corresponding inlet or outlet or the second connector relative to the seat back to adapt to the flexible display screen with different tilt angles.

[0019] In a second aspect, the present invention also provides a vehicle comprising at least two seat backs arranged side by side, wherein one of the seat backs is provided with a seat display device as described in any one of the above technical solutions, and the remaining seat backs are provided with a second connector and a second angle adjustment mechanism as described in any one of the above technical solutions.

[0041] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0042] It should be noted that in the description of this invention, terms such as "upper," "lower," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the relevant devices or elements must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation" and "connection" 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. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0044] To solve the technical problems described in the background section above, first refer to... Figure 5 , Figure 10 and Figure 11 The present invention provides a seat display device, which includes a flexible display module 8 and a first angle adjustment mechanism 6. Both the flexible display module 8 and the first angle adjustment mechanism 6 are disposed inside the seat back 1. The flexible display module 8 includes a flexible display 81. The back of the seat back 1 is provided with an inlet 4 for extending the flexible display 81 to the outside of the seat back or retracting it into the seat back. The first angle adjustment mechanism 6 is configured to adjust the tilt angle of the flexible display 81 relative to the seat back 1 to adapt to different reclining angles of the seat back 1.

[0045] In the above embodiments, the flexible display screen 81 is flexible and can be bent at will, thereby meeting the requirements for winding. The flexible display screen 81 can be, but is not limited to, organic light-emitting LEDs, micro-light-emitting LEDs, and liquid crystal displays. It is understood that the present invention does not specifically limit the type of flexible display screen 81 used, and can flexibly set according to actual usage requirements without departing from the basic principles of the present invention. For example, because different types of flexible display screens 81 have different costs, their installation on a vehicle will result in different overall vehicle costs; the overall vehicle cost can be considered as one of the factors in selecting the type of flexible display screen 81.

[0046] In one embodiment, see further. Figure 5 , Figure 10 and Figure 11 The flexible display module 8 also includes a support member 83 and a scroll 82. The support member 83 is rotatably connected inside the seat back 1 and is located near the inlet / outlet on the seat to facilitate the extension or retraction of the flexible display from the inlet / outlet. To make the scroll and flexible display components clearer, in Figure 5 The middle support component is not shown; the scroll 82 is rotatably connected to the support component 83. Figure 10 and Figure 11 The image is not shown due to the angle issue. The scroll 82 is configured to automatically rewind the flexible display screen 81. The first angle adjustment mechanism 6 drives the support member 83 to rotate to adjust the tilt angle of the flexible display screen 81 relative to the seat back 1.

[0047] Specifically, the flexible display module 8 also includes a rewinder 12, which is configured to apply a rewinding force to the reel 82 to wind the flexible display 81 onto the reel 82. The rewinder 12 can be a spiral spring, which applies a rewinding force to the reel 82, thus enabling the reel 82 to automatically retract the flexible display 81. Of course, it is understood that the rewinder 12 is not limited to a spiral spring; it can also be a motor 62, which directly drives the reel 82 to rotate, thereby achieving the automatic retraction and extension of the flexible display 81, which is also within the scope of protection of this application. However, in this application, designing the rewinder 12 as a spiral spring is a preferred embodiment, which has the advantage of low cost.

[0048] The specific shape of the support member 83 is not specifically limited in this invention; it can be flexibly set according to the usage requirements without departing from the basic principles of this invention. For example, as shown... Figure 10 As shown, the support member 83 has a groove structure, and the roller 82 is rotatably connected inside the support member 83, so that the flexible display screen 81 is wound up on the roller 82. The groove of the support member 83 faces the back of the seat back 1, which makes it easy for the flexible display screen 81 to extend or retract from the inlet and outlet 4.

[0049] The flexible display screen 81 designed in this invention can be pulled out when in use and hidden inside the seat back 1 when not in use, thus avoiding intrusion into the vehicle's interior space and reducing space occupation. Furthermore, the first angle adjustment mechanism 6 can adjust the tilt angle of the flexible display screen 81 relative to the seat back 1. Figures 8 to 9 As shown, the flexible display screen 81 is positioned relative to the seat back 1 from... Figure 8 Adjust the angle as shown. Figure 9 The angle shown allows passengers to have a good viewing experience regardless of the angle at which the seat back is reclined or the passenger's posture.

[0050] In this invention, the flexible display screen 81 is communicatively connected to the drive circuit board 11 via a flexible circuit board. The drive circuit board 11 may be, but is not limited to, being located at the end of the roll 82. The drive circuit board 11 is connected to an external power supply device via a rotary joint.

[0051] In one embodiment, see Figure 10 and Figure 11 The first angle adjustment mechanism 6 includes a motor 62 and a gear assembly 61. The motor 62 is fixed inside the seat back 1. The motor 62 drives the support member 83 to rotate through the gear assembly 61 to adjust the tilt angle of the flexible display screen 81 relative to the seat back 1.

[0052] Specifically, such as Figure 10 and 11 As shown, the motor 62 is located on the back side of the support member 83, that is, on the side of the support member 83 away from the inlet / outlet 4. The gear assembly 61 includes a first gear 611 and a second gear 612 that mesh with each other. The first gear 611 is fixedly connected to the output shaft of the motor 62, and the second gear 612 is fixed to the support member 83. The motor 62 drives the first gear 611 to rotate, thereby causing the second gear 612 to rotate. The meshing of the first gear 611 and the second gear 612 enables the second gear 612 to rotate while the motor 62 drives the first gear 611 to rotate, thus realizing the angle adjustment of the flexible display screen 81 driven by the support member 83.

[0053] For example, such as Figure 11 As shown, the support member 83 has a slotted structure, and the second gear 612 is fixed to the outer top end of the support member 83. The second gear 612 can be, but is not limited to, a sector gear. Of course, the second gear 612 is not limited to being fixed to the outer top end of the support member 83; it can also be fixed to the outer bottom end or the middle part of the support member 83, etc. However, the center of the second gear 612 needs to be on the same straight line as the rotation axis of the support member 83. Without deviating from the basic principles of this invention, the setting position of the second gear 612 can be flexibly set according to the actual usage.

[0054] Additionally, it should be noted that the support member 83 can be rotatably connected to the inside of the seat back 1 via a rotating shaft. At this time, the second gear 612 can also be fixed on the rotating shaft. By driving the rotating shaft, the support member 83 can be rotated to adjust the tilt angle of the flexible display screen 81, which is also within the protection scope of this invention.

[0055] In the above embodiment, the motor 62 drives the first gear 611 to rotate the second gear 612, thereby causing the support member 83 to rotate the flexible display screen 81. This realizes the automatic adjustment of the tilt angle of the flexible display screen 81 relative to the seat back 1, making it more convenient to use. Moreover, the gear has multiple teeth, making the adjustment more precise.

[0056] Furthermore, it should be noted that although the first angle adjustment mechanism 6 described above uses a motor 62 to drive the first gear 611 to drive the second gear 612 to rotate the support member 83, this is not limiting. Other structures are also possible, such as directly using a motor 62 to drive the support member 83 to rotate, or using a cylinder to drive a rack and pinion to rotate the gears. All of these are within the scope of protection of this invention. Therefore, without departing from the basic principles of this invention, the first angle adjustment mechanism 6 can be flexibly configured according to actual usage conditions.

[0057] In one embodiment, the seat display device further includes a damping mechanism 9, which is disposed on the support member 83. The damping mechanism 9 is configured to apply different levels of pressure to the flexible display screen 81 to limit the extension and retraction speed of the flexible display screen 81 to varying degrees. When the support member 83 has a groove structure, the damping mechanism 9 is disposed on the inner side of the support member 83.

[0058] In the above embodiments, the damping mechanism 9 designed by the present invention can exert pressure on the flexible display screen 81, limiting the extension and retraction speed of the flexible display screen 81. Due to different pressure magnitudes, the retraction speed of the flexible display screen 81 is different, thereby adjusting the pressure magnitude to adjust the retraction speed, so that the flexible display screen 81 will not be too fast when automatically rewinding, improving safety, and the flexible display screen 81 can be pressed into a suspended state at any position, making it more convenient to use.

[0059] In one embodiment, see Figure 5 , Figure 6 and Figure 7The damping mechanism 9 includes two pressure columns 92 and an elastic element 91. The two pressure columns 92 are mounted on the support member 83, and at least one pressure column 92 is connected to the support member 83 via the elastic element 91. The flexible display screen 81 passes between the two pressure columns 92. At least one pressure column 92 is made of an electromagnet. When energized, the two pressure columns 92 repel each other, allowing the flexible display screen 81 to extend and retract. When de-energized, the two pressure columns 92, under the action of the elastic element 91, press the flexible display screen 81 to stop its extension and retraction. When the electromagnet is energized, the two pressure columns 92 repel each other, and the pressure column 92 connected to the elastic element 91 moves away from the flexible display screen 81, thereby reducing the pressure on the flexible display screen 81. This ensures that the flexible display screen 81 passes between the two pressure columns 92 at a slower speed, allowing it to retract slowly. When the electromagnet is de-energized, the elastic force of the elastic element 91 causes the two pressure columns 92 to press the flexible display screen 81, preventing it from extending and retracting, thus achieving the purpose of suspension.

[0060] Specifically, in the first embodiment, one pressure column 92 is fixedly connected to the support member 83, and the other pressure column 92 is connected to the support member 83 via an elastic member 91, wherein at least one pressure column 92 is made of an electromagnet; in the second embodiment, two pressure columns 92 are respectively connected to the support member 83 via elastic members 91, wherein at least one pressure column 92 is made of an electromagnet. In both embodiments, the pressure column 92 cannot rotate relative to the support member 83. However, the present invention is not limited to the method in which the pressure column 92 cannot rotate relative to the support member 83; the pressure column 92 can also rotate relative to the support member 83, that is, the pressure column 92 can rotate along the extension and retraction direction of the flexible display screen 81, which is also within the protection scope of the present invention.

[0061] It should be noted that although the damping mechanism 9 is constructed using two pressure columns 92 and an elastic element 91 as described above, this does not limit the scope of protection of the present invention. The damping mechanism 9 can also have other structures. For example, the damping mechanism 9 includes two pressure columns 92 and an electric push rod. One pressure column 92 is connected to the support member 83, and the other pressure column 92 is connected to the electric push rod. The electric push rod is fixed to the support member 83. The electric push rod drives the pressure column 92 and the other pressure column 92 to jointly apply pressure to the flexible display screen 81, thereby achieving the ability to suspend or reduce the contraction speed at any time during the extension and retraction process. However, the structure of the damping mechanism 9 described above, consisting of two pressure columns 92 and an elastic element 91, is considered a preferred embodiment of the present invention and has the advantages of simple structure and low cost.

[0062] Of course, in this invention, the number of damping mechanisms 9 is not specifically limited; it can be one or two, and can be flexibly set according to actual usage without departing from the basic principles of this invention. Figure 6 In the middle, there is one damping mechanism 9.

[0063] In the above embodiment, the flexible display screen 81 passes between the two pressure columns 92. When the power is off, the elastic force of the elastic element 91 causes the two pressure columns 92 to clamp the flexible display screen 81, allowing it to suspend at any position. When the power is on, the two pressure columns 92 repel each other, allowing the flexible display screen 81 to pass between the two pressure columns 92. By controlling the gap between the two pressure columns 92, the pressure on the flexible display screen 81 can be adjusted, thus achieving both slow retraction and suspension. The operation is simple and convenient, and the manufacturing cost is low.

[0064] In one embodiment, see Figure 5 A guide rod 10 is fixed on the support member 83 at the part corresponding to the inlet / outlet 4. The flexible display screen 81 extends from the inlet / outlet 4 perpendicularly to the inlet / outlet 4, bypassing the guide rod 10. The damping mechanism 9 is located between the guide rod 10 and the reel 82. When the rewinder 12 is a spiral spring, one end of the spiral spring hooks onto the guide rod 10, and the other end of the spiral spring is installed on the reel 82, thereby realizing the automatic winding function of the reel 82 by utilizing the winding force of the spiral spring.

[0065] In the above embodiments, the guide rod 10 enables the flexible display screen 81 to extend or retract vertically from the inlet / outlet 4, making the process simpler and minimizing friction between the flexible display screen 81 and its surroundings. This helps to prevent damage to the flexible display screen 81 and provides a mounting position for the telescopic mechanism 5 to be installed later.

[0066] In one embodiment, see Figure 5 and Figure 13 The seat display device also includes a telescopic mechanism 5, which is located on the back side of the flexible display screen 81 between the guide rod 10 and the inlet / outlet 4. The telescopic mechanism 5 can extend and retract with the flexible display screen 81 to provide back support for the extended flexible display screen 81.

[0067] The present invention provides a telescopic mechanism 5 on the back side of the flexible display screen 81, such as... Figure 15-18 The telescopic mechanism 5 can extend and retract along with the flexible display screen 81, providing stable back support after the flexible display screen 81 is extended and unfolded. It has good stability and helps to improve the user experience.

[0068] In one embodiment, see Figure 14 The telescopic mechanism 5 is a telescopic grid structure. The first end of the telescopic mechanism 5 is fixedly connected to the first end of the flexible display screen 81. The second end of the telescopic mechanism 5 is fixed with a stop mechanism 7 to limit the movement position of the second end of the telescopic mechanism 5 so that the telescopic mechanism 5 can automatically follow the flexible display screen 81 to extend and retract.

[0069] Specifically, the telescopic mechanism 5 may, but is not limited to, be made of plastic. See also Figure 13 A guide rail 13 is fixed to the support member 83 on the back side of the flexible display screen 81, and the telescopic mechanism 5 retracts along the trajectory of the guide rail 13. (See reference...) Figure 14 The stopping mechanism 7 includes a stopping member 72 and a third connecting member 71. One end of the third connecting member 71 is connected to the second end of the telescopic mechanism 5, and the other end of the third connecting member 71 is connected to the stopping member 72. The stopping member 72 is slidably connected to the guide rail 13. The size of the stopping member 72 is larger than the size of the inlet and outlet 4 so that when the telescopic mechanism 5 extends to the outside of the seat, the stopping member 72 is locked inside the seat back 1, allowing the telescopic grille structure to open smoothly. At the same time, the stopping member 72 supports the third connecting member 71, thereby indirectly supporting the second end of the telescopic mechanism 5 and ensuring that the telescopic mechanism 5 does not fall off. The movement of the stopping member 72 along the guide rail 13 ensures that the telescopic mechanism 5 and the flexible display screen 81 do not shift when retracting.

[0070] Additionally, the third connector 71 is flexible, allowing it to bend along with the flexible display screen 81. This facilitates the extension of the telescopic grille beyond the inlet / outlet 4, enabling it to bend along with the flexible display screen 81. The flexible display screen 81 bends and connects to the seat back 1 for passenger viewing. Exemplarily, the third connector 71 includes multiple side-by-side connecting rods, with adjacent connecting rods hinged together.

[0071] In one embodiment, see Figure 1 and 5 The first end of the flexible display screen 81 is fixed with a first connector 3, and the back of the seat back 1 is provided with a second connector 2. The first connector 3 and the second connector 2 are detachably connected to limit the length of the flexible display screen 81 extending to the outside of the seat back 1. The size of the first connector 3 is larger than the size of the inlet and outlet 4.

[0072] Specifically, see Figure 12 Both the first connector 3 and the second connector 2 are hook-shaped structures, such as an L-shape. The first connector 3 and the second connector 2 hook each other to achieve a detachable connection between the first end of the flexible display screen 81 and the seat back 1. The bottom end of the second connector 2 is fixed with a stop 72 to prevent the first connector 3 from falling off, thus ensuring that the flexible display screen 81 will not fall off after being hooked. When the flexible display screen 81 is in the retracted state, the first connector 3 is stuck on the outside of the inlet and outlet 4, which facilitates the subsequent stretching of the flexible display screen 81.

[0073] Of course, it is understood that the detachable connection between the first connector 3 and the second connector 2 is not limited to a hook-and-loop connection; other methods can also be used, such as magnetic attraction. The first connector 3 and the second connector 2 are magnetic, and they are connected by mutual attraction. They can also be detached under external force, which is also within the scope of this invention. Therefore, without departing from the basic principles of this invention, the connection structure of the first connector 3 and the second connector 2 can be flexibly designed according to actual usage.

[0074] The first connector 3 and the second connector 2 of this invention are detachably connected, which can fix or loosen the extended flexible display screen 81, making it easy to use and hide.

[0075] In one embodiment, a second angle adjustment mechanism is also provided in the seat back 1. The inlet / outlet 4 and the second connector 2 are both connected to a second angle adjustment mechanism. The second angle adjustment mechanism is configured to adjust the tilt angle of the corresponding inlet / outlet 4 or the second connector 2 relative to the seat back 1 to adapt to the flexible display screen 81 with different tilt angles.

[0076] Specifically, the second angle adjustment mechanism can be the same as the first angle adjustment structure. In this invention, it is preferable that the second angle adjustment mechanism and the first angle adjustment mechanism 6 adopt an electric adjustment method, which helps to ensure the consistency of the adjustment angle.

[0077] Furthermore, it is understood that this application does not specifically limit the number of second connecting members 2 provided on the back of the seat back 1, and can flexibly set according to actual usage.

[0078] On the other hand, the present invention also provides a vehicle including at least two seat backs 1 arranged side by side, one of which is provided with a seat display device as described in any of the above technical solutions, and the remaining seat backs 1 are provided with a second connector 2 and a second angle adjustment mechanism as described in any of the above technical solutions.

[0079] See Figure 1 The flexible display screen 81 is in a retracted state. One of the seat backrests 1 has an inlet / outlet 4 and a second connector 2 on its back. The other seat backrest 1 has two second connectors 2 on its back. These two connectors are distributed at both ends of the seat backrest 1. The flexible display screen 81 is stored and hidden inside the seat backrest 1, so as not to affect passengers getting on and off the vehicle or occupy space.

[0080] See Figure 2 The flexible display screen 81 is pulled out from the inlet / outlet 4 into a private state, that is, after the flexible display screen 81 is pulled out, it is connected to the back of the same seat back 1, which is suitable for one person to watch.

[0081] See Figure 3 The flexible display screen 81 is in the sharing state. At this time, the first connector 3 on the flexible display screen 81 is connected to the second connector 2 on the second seat back 1 near the entrance / exit 4.

[0082] See Figure 4 The flexible display screen 81 is in the giant screen state. At this time, the first connector 3 on the flexible display screen 81 is connected to the second connector 2 on the second seat back 1 away from the entrance and exit 4. At this time, the flexible screen is pulled out to present its maximum state.

[0083] The flexible display screen 81 designed in this invention can be in various forms, from completely hidden, private, shared to giant screen, offering diverse usage options. This allows the flexible display screen 81 to freely expand and contract to a specific size to adapt to different scenarios. When not in use, it can be completely hidden, without intruding on the vehicle's interior space, while still achieving a super-large screen display effect. It also features a first angle adjustment mechanism 6 that adjusts the tilt angle of the flexible display screen 81 relative to the seat back 1, allowing for angle adjustment to ensure a better experience for passengers in different seating postures.

[0084] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
