In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0060] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0061] Unless otherwise specified, the front-to-back direction in this application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0062] Reference below Figures 1-15 The screen assembly 102 according to an embodiment of the present invention is described. The screen assembly 102 can realize flexible and stable bending deformation of the screen component 2, is not prone to shaking or damage, and improves the user experience. In addition, the thickness of the entire screen assembly 102 is very small, does not require a lot of space, has a compact structure, and is easy to arrange on the vehicle. The screen assembly 102 is in good stress condition and is not prone to damage.

[0063] like Figures 1-15 As shown, a screen assembly 102 according to one embodiment of the present invention includes: a mounting housing 1, a screen assembly 2, a drive assembly 3, and a connecting rod assembly 4. It should be noted that the screen assembly 102 of the present invention can be applied to the back of a vehicle seat 100 for viewing by rear passengers, or to the vehicle's central control screen for viewing by the driver and front passenger. Of course, it can also be applied to other locations in the vehicle, thus having a wide range of uses.

[0064] The mounting housing 1 serves as the support and mounting base for the entire screen assembly 2, ensuring stable installation and use of the screen assembly 2 and protecting the screen assembly 2. When the screen assembly 2 is not in use, the screen assembly 2 can be stored in the mounting housing 1 to avoid damage to the screen assembly 2. A storage slot is provided on the side of the mounting housing 1 facing the screen assembly 2. The shape and size of the storage slot match those of the screen assembly 2, so that the screen assembly 2 can be embedded in the storage slot to store the screen assembly 2.

[0065] The mounting housing 1 is provided with a sliding guide 5 extending along a first direction.

[0066] Specifically, the first direction is the extension direction of the screen assembly 2, that is, the length direction. When the screen assembly 102 is installed on the vehicle, refer to the attached Figure 15 As shown, the first direction can be the left and right direction of the vehicle, so that a sliding guide 5 extending along the first direction, i.e., the left and right direction, is provided inside the mounting shell 1, so that the first sliding member 41 can slide stably on the sliding guide 5 along the length direction of the screen assembly 2, i.e., the left and right direction.

[0067] The screen assembly 2 has a first area 21 and a second area 22 distributed along a first direction, and the first area 21 is connected to the mounting housing 1 .

[0068] That is, the first area 21 and the second area 22 can be distributed along the length direction of the screen assembly 2, that is, the left and right directions. Figure 1 As shown, the first area 21 can be located on the left or right side of the second area 22. The first area 21 is connected to the mounting shell 1, that is, the first area 21 of the screen assembly 2 is fixedly connected to the mounting shell 1. The first area 21 is used to ensure the connection stability and display function of the screen assembly 2. It is a non-deformable area. The second area 22 can be set as a variable area, which can bend and deform, providing the screen assembly 2 with more display forms and interaction possibilities, thereby improving the user experience.

[0069] Furthermore, the connecting rod assembly 4 includes a sliding structure and a rotating connecting rod 43. The sliding structure and the sliding guide 5 slide in cooperation along the first direction, that is, the sliding structure can slide along the extending direction of the sliding guide 5. The extending direction of the sliding guide 5 is the first direction. Figure 3 As shown, the first direction is the length direction of the screen, that is, the left-right direction of the screen, that is, the sliding guide 5 is extended along the left-right direction of the screen, and the sliding structure slides along the left-right direction of the screen.

[0070] Among them, the two ends of the rotating link 43 are rotatably connected to the sliding structure and the second area 22 respectively, and the driving component 3 is used to drive the sliding structure to slide along the sliding guide 5 to drive the second area 22 to bend and deform in the second direction relative to the first area 21 through the rotating link 43, and the second direction intersects with the first direction.

[0071] Specifically, the first direction may or may not intersect the second direction perpendicularly. Figure 1 and attached Figure 15 As shown, when the first direction is the left-right direction of the vehicle or the length direction of the screen, the second direction may be other directions intersecting with the left-right direction of the screen, for example, referring to the attached Figure 15 As shown, when they intersect vertically, the second direction can be the front-to-back direction of the vehicle, that is, the thickness direction of the screen. The two ends of the rotating link 43 are rotatably connected to the sliding structure and the second area 22 respectively, that is, the rotating link 43 can rotate relative to the sliding structure and the second area 22. In practice, when the driving assembly 3 is working, it provides power to the sliding structure to drive the sliding structure to slide along the sliding guide 5, and drives the second area 22 to bend and deform in the second direction, that is, the front-to-back direction, relative to the first area 21 through the rotating link 43, so that the screen assembly 2 can be stably bent into various shapes to meet the user's usage needs and enhance the user experience.

[0072] And reference Figure 1 As shown, the sliding guide 5, the driving assembly 3 and the connecting rod assembly 4 can all be installed in the installation shell 1. The connecting rod assembly 4 is arranged and moves along the Y direction, that is, the left and right direction, so that the X-direction dimension of the entire screen assembly 102, that is, the thickness dimension in the front and rear direction is very small, does not need to occupy a lot of space, and has a compact structure, which makes it easy to be arranged on the vehicle. When arranged on the back of the seat 100, it can reduce the space occupied by the back row, and the driving assembly 3 drives the connecting rod assembly 4 to move in coordination, so that the power of the driving assembly 3 is transmitted from the sliding structure to the rotating link 43. Through the rotation of the rotating link 43, the stable bending deformation of the screen assembly 2 is achieved, the deformation stability of the screen assembly 2 is ensured, and it is not easy to shake or damage, thereby improving the user's usage experience, and the force applied to the screen assembly 2 is basically borne by the sliding structure and the sliding guide 5, and the rotating link 43 is subjected to very little force, so that the screen assembly 102 is in good force condition and is not easy to be damaged, thereby ensuring the stability and reliability of the screen assembly 2, the bending deformation is stable, and the service life is improved.

[0073] According to the screen assembly 102 of an embodiment of the present invention, the first area 21 of the screen assembly 2 is connected to the mounting shell 1 to fix the screen assembly 2, so that the first area 21 cannot be deformed. Through the cooperation of the driving assembly 3 and the connecting rod assembly 4, while ensuring the stability of the screen assembly 2, the second area 22 of the screen assembly 2 can be flexibly and stably bent and deformed, and is not prone to shaking or damage, thereby improving the user experience. In addition, the thickness of the entire screen assembly 102 is very small, does not require a lot of space, has a compact structure, and is easy to arrange on a vehicle. The screen assembly 102 is in good stress condition and is not prone to damage.

[0074] In some embodiments, refer to the attached Figure 1 and attached Figure 3 As shown, the sliding structure includes a first sliding member 41 and a sliding link 42. The first sliding member 41 is a bridge connecting the drive assembly 3 and the screen assembly 2. Figure 3 As shown, the first sliding member 41 can slide along the extension direction of the sliding guide member 5 , that is, the length of the sliding guide member 5 is the sliding displacement range of the first sliding member 41 .

[0075] Furthermore, one end of the first link sliding link 42 is connected to the drive assembly 3 and the other end is connected to the first sliding member 41. One end of the second link rotating link 43 is rotatably connected to the first sliding member 41, and the other end of the second link rotating link 43 is rotatably connected to the second region 22. In other words, the drive assembly 3 can provide power to transmit to the sliding link 42, so that the sliding link 42 can drive the first sliding member 41 to slide linearly along the sliding guide 5, thereby transmitting power to the first sliding member 41. As the first sliding member 41 slides, it can drive the rotating link 43 to rotate, so that one end of the rotating link 43 can rotate relative to the first sliding member 41, and the other end of the rotating link 43 can rotate relative to the second region 22.

[0076] Among them, the driving component 3 is suitable for driving the first connecting rod sliding link 42 to move along the first direction, and driving the first sliding member 41 to slide along the sliding guide member 5, and the first sliding member 41 pushes the second connecting rod rotating link 43 to drive the screen component 2 to bend and deform in the second direction.

[0077] Specifically, refer to the attached Figure 1 and attached Figure 3 As shown, the first direction is Figure 1 The left and right directions of the screen are shown in the , and the second direction is Figure 1The thickness direction of the screen shown is the front direction. In practice, when the drive assembly 3 is working, the sliding link 42 is driven to move in a first direction, that is, the left-right direction. The sliding link 42 moves to drive the first sliding member 41 to slide on the sliding guide 5. Then, when the first sliding member 41 slides, it can push the rotating link 43 to rotate. That is, through the rotation of the rotating link 43, the force is transmitted to the second area 22 of the screen assembly 2, so that the rotating link 43 can drive the second area 22 of the screen assembly 2 to bend and deform in the second direction, that is, the front-back direction, so that the screen assembly 2 can be stably bent into various shapes to meet the user's usage needs and enhance the user experience.

[0078] In this embodiment, the force exerted on the screen assembly 2 is basically borne by the first sliding member 41 and the sliding guide member 5, and the rotating connecting rod 43 is subjected to very little force, thereby reducing the force exerted on the second area 22 and improving the service life of the screen assembly 2.

[0079] In some embodiments, there are two second regions 22 , the two second regions 22 are spaced apart along the first direction, and the first region 21 is located between the two second regions 22 .

[0080] That is, the second regions 22 are located on either side of the first region 21, and the second regions 22 on either side can bend and deform to the same or different degrees, that is, the second regions 22 can deform uniformly or inconsistently, thereby achieving more precise deformation. In practice, the rotating connecting rod 43 can push the two second regions 22 of the screen assembly 2 to move on both sides, for example, closer to or away from the housing assembly, to achieve bending deformation of the screen assembly 2 in the second direction, which is applicable to more scenarios.

[0081] like Figure 1 and Figure 8 As shown, the first direction corresponds to Figure 8 In the left and right directions shown in , the second areas 22 are located on the left and right sides of the first area 21 , and the rotating connecting rod 43 can push the two second areas 22 of the screen assembly 2 to move forward or back and forth.

[0082] There are two connecting rod assemblies 4 , and the driving assembly 3 is adapted to drive the sliding connecting rods 42 of the two connecting rod assemblies 4 to move toward or away from each other along a first direction.

[0083] Specifically, if Figure 1As shown, two connecting rod assemblies 4 are provided, and both connecting rods include a first sliding member 41, a sliding connecting rod 42, and a rotating connecting rod 43. The rotating connecting rod 43 can be constructed into a slightly bent shape to facilitate connection with the first sliding member 41 and the rotating connecting rod 43, and to move along the first direction. The two rotating connecting rods 43 are rotatably connected to the two second areas 22, respectively, so that the two connecting rod assemblies 4 can respectively control the second areas 22 on the screen assembly 2. When the driving assembly 3 is started, the driving assembly 3 drives the sliding connecting rods 42 of the two connecting rod assemblies 4 to move toward or away from each other along the first direction, that is, the sliding connecting rods 42 can move toward or away from each other in the left and right directions, so that the second areas 22 can bend inwards to approach the mounting shell 1, or expand outwards to move away from the mounting shell 1.

[0084] It should be noted that the bending deformation of the screen assembly 2 can be set to three forms, for example, a convex state, a concave state and a flat state.

[0085] like Figure 4 、 Figure 6 and Figure 7 As shown, when the two sliding links 42 move along the first direction toward each other, the two sliding links 42 can respectively drive the two first sliding members 41 to slide on the sliding guide member 5 toward each other, that is, move inward. At the same time, the first sliding member 41 pulls the rotating link 43 to move inward, so that the rotating link 43 drives the screen assembly 2 to move backward to pull the screen assembly 2 closer to the mounting shell 1, realizing the change of the screen assembly 2 from concave to straight, and from flat to convex, that is, the change of the second area 22 from being away from the mounting shell 1 to being close to the mounting shell 1.

[0086] When the two sliding links 42 move away from each other along the first direction, the two sliding links 42 can respectively drive the two first sliding members 41 to slide on the sliding guide 5 in the direction away from each other, that is, move inward. At the same time, the first sliding member 41 pushes the rotating link 43 to move outward, so that the rotating link 43 drives the screen assembly 2 to move forward to push the screen assembly 2 away from the mounting shell 1, realizing the change of the screen assembly 2 from convex to flat, and from flat to concave, that is, the change of the second area 22 from close to the mounting shell 1 to away from the mounting shell 1.

[0087] In some embodiments, the first region 21 is a middle region of the screen assembly 2 in the first direction, and the two second regions 22 are two end regions of the screen assembly 2 in the first direction.

[0088] Specifically, if Figure 8 As shown, the first direction corresponds to Figure 8As shown in the left and right directions, the screen assembly 2 can be divided into three areas, a middle area and two end areas. The middle area is located in the middle of the screen assembly 2, and the two end areas are located at both ends of the screen assembly 2, that is, the left and right sides of the middle area.

[0089] Thus, when the driving assembly 3 drives the sliding link 42 to move, the middle region remains stationary, and the movement of the rotating link 43 can drive the two end regions to bend inward to approach the mounting housing 1, or to expand outward to move away from the mounting housing 1. The two end regions are controlled by the two link assemblies 4, thereby achieving synchronous deformation of the two end regions, so that the left and right ends of the screen assembly 2 deform uniformly and stably.

[0090] In some embodiments, in the first direction, the driving assembly 3 is located in the middle of the screen assembly 2 , and the two connecting rod assemblies 4 are symmetrically distributed relative to the driving assembly 3 .

[0091] Specifically, if Figure 8 As shown, the first direction corresponds to Figure 8 In the left and right directions shown in the figure, the driving assembly 3 is located in the middle, and the two connecting rod assemblies 4 are symmetrically distributed on the left and right sides relative to the driving assembly 3. In this way, the entire screen assembly 2 can maintain balance during bending deformation, reducing distortion or instability caused by uneven force, further improving the deformation consistency of the left and right ends of the screen assembly 2, and can more easily use one driving assembly 3 to drive the two connecting rod assemblies 4 to move. There is no need to set up two groups of driving assemblies 3 to drive the two connecting rod assemblies 4 to move respectively, which simplifies the structure and helps to reduce the thickness of the screen assembly 102.

[0092] In some embodiments, the mounting housing 1 is provided with a mounting bracket 13, and the mounting bracket 13 is used to mount and support the drive assembly 3, such as Figure 1 As shown, the mounting bracket 13 may be constructed in a cross shape, extending upward, downward, leftward, and rightward directions respectively.

[0093] The driving assembly 3 includes a driving member 31, a transmission structure 32 and a second sliding member 33. The second sliding member 33 can slide relative to the mounting bracket 13 along a first direction. The driving member 31 is connected to the second sliding member 33 through the transmission structure 32. The driving member 31 is suitable for driving the second sliding member 33 to move along the first direction relative to the mounting bracket 13 through the transmission structure 32. The second sliding member 33 is connected to one end of the sliding link 42.

[0094] Specifically, if Figure 8 As shown, the first direction corresponds to Figure 8As shown in the left-right direction, the second sliding member 33 is mounted on the mounting bracket 13 and can slide stably in the left-right direction. The driving member 31 is used to provide power to the transmission structure 32. The driving member 31 can be configured as a motor, etc. The transmission structure 32 then transmits the power to the second sliding member 33 to drive the sliding member to move in the left-right direction relative to the mounting bracket 13. The second sliding member 33 is connected to one end of the sliding link 42, so that when the second sliding member 33 slides, it can drive the sliding link 42 to move.

[0095] In some embodiments, the transmission structure 32 includes a transmission worm 321, a transmission gear 322 and a transmission screw 323. The transmission worm 321 is installed at the output end of the driving member 31, the transmission worm 321 is meshed with the transmission gear 322, the transmission gear 322 is coaxially connected with the transmission screw 323, the axial direction of the transmission screw 323 is along the first direction, the transmission screw 323 is rotatably installed on the mounting bracket 13, and the second sliding member 33 is sleeved on the outside of the transmission screw 323 and is threadedly engaged with the transmission screw 323.

[0096] Specifically, if Figure 1 As shown, the transmission structure 32 includes a transmission worm 321, a transmission gear 322 and a transmission screw 323. The first direction corresponds to Figure 1 As shown in the left and right directions, the transmission worm 321 is installed at the output end of the driving member 31, so that the power of the driving member 31 can be transmitted to the transmission worm 321 to drive the transmission worm 321 to rotate. When the transmission worm 321 rotates, it can drive the transmission gear 322 meshing with it to rotate, thereby realizing power transmission from the driving member 31 to the transmission gear 322.

[0097] The transmission screw 323 is mounted on the mounting bracket 13 along the axial direction of the transmission screw 323 in the left-right direction. The transmission gear 322 is located along the transmission screw 323 and in the middle of the transmission screw 323 and is coaxially connected to one end of the transmission screw 323. The other end of the transmission screw 323 is rotatably connected to the mounting bracket 13. The second sliding member 33 is provided with an internal thread for the transmission screw 323 to pass through. The transmission screw 323 is provided with an external thread that matches the second sliding member 33. Thus, the second sliding member 33 can be sleeved on the outside of the transmission screw 323 and threadedly engaged with the transmission screw 323. In this way, when the transmission worm 321 drives the transmission gear 322 to rotate, the transmission gear 322 can simultaneously drive the transmission screws 323 on both sides to rotate. The rotation of the transmission screw 323 then drives the second sliding member 33 to slide along the axial direction of the transmission screw 323, thereby converting the rotational motion into the linear motion of the second sliding member 33.

[0098] It should be noted that the second sliding member 33 has a self-locking function. When the driving member 31 stops moving, the second sliding member 33 can be stationary and self-locked on the transmission screw 323, preventing further movement. This ensures that the sliding link 42 and the rotating link 43 remain stationary, and thus the screen assembly 2 remains stationary. In practice, the travel of the second sliding member 33 can be set so that the second sliding member 33 self-locks when it moves to a specific position, allowing the screen to be stably maintained in a convex, flat, or concave state.

[0099] In some embodiments, the axial direction of the transmission worm 321 is perpendicular to the axial direction of the transmission screw 323 .

[0100] Specifically, if Figure 4 As shown, the driving member 31 is installed on the mounting bracket 13 in the up and down direction, the axial direction of the transmission worm 321 is in the up and down direction, and the axial direction of the transmission screw 323 is in the left and right direction, so that the axial direction of the transmission worm 321 is perpendicular to the axial direction of the transmission screw 323. In this way, the transmission screw 323 and the transmission worm 321 can be arranged in the Z direction, that is, the up and down direction, reducing the space occupied by the driving member 31, the transmission worm 321 and the transmission screw 323 in the X direction, that is, the front and back direction, which is conducive to further realizing the lightness and thinness of the screen assembly 102 and reducing the thickness. The axial verticality can also improve the transmission efficiency and reduce the generation of transmission noise.

[0101] In some embodiments, the mounting bracket 13 further includes at least one guide rod 131 . The guide rod 131 is parallel to and spaced apart from the transmission screw 323 . The second sliding member 33 is sleeved outside the guide rod 131 and is slidable along the guide rod 131 .

[0102] That is to say, the mounting bracket 13 may be provided with two, three or more guide rods 131, which are used to guide the second sliding member 33, thereby improving the movement smoothness of the second sliding member 33, and avoiding shaking and offsetting of the second sliding member 33 during linear movement, thereby facilitating accurate and stable control of the bending deformation of the screen assembly 2.

[0103] Specifically, if Figure 2 As shown, the mounting bracket 13 is provided with four guide rods 131, and the four guide rods 131 guide the two second sliding members 33 respectively. Every two guide rods 131 are distributed on the upper and lower sides of the transmission screw 323 in parallel and spaced apart in the up and down directions. The second sliding member 33 is provided with a through hole for the guide rod 131 to pass through, so that the two guide rods 131 can pass through the through hole, so that the second sleeve is arranged outside the guide rod 131 and the second sliding member 33 can slide stably along the two guide rods 131, thereby reducing the noise generated by the unstable movement of the second sliding member 33 and the inconsistent deformation of the two ends of the screen assembly 2.

[0104] In some embodiments, the screen assembly 102 also includes a connecting rope 61, the second sliding member 33 is equipped with a pulley 62, the pulley 62 is equipped with a pre-tensioning spring 63, and the screen assembly 2 is also provided with a pull rope fixing point 23 in the second area 22, one end of the connecting rope 61 is connected to the pre-tensioning spring 63 and the other end is connected to the pull rope fixing point 23.

[0105] Specifically, if Figure 1 、 Figure 4-Figure 7 As shown, the screen assembly 102 is also provided with a connecting rope 61, and a pulley 62 is provided on the side of the second sliding member 33 facing the screen component 2. The pulley 62 can move along the left and right directions together with the second sliding member 33. The pulley 62 is installed with a pre-tensioning spring 63. The pre-tensioning spring 63 can provide continuous tension to the connecting rope 61, keeping the rope taut, thereby facilitating the adjustment of the position and shape of the screen component 2.

[0106] The screen assembly 2 is provided with a drawstring fixing point 23 in the second region 22. The drawstring fixing point 23 is used to fix the end of a connecting drawstring 61 so that the drawstring can pull the screen assembly 2. One end of the connecting drawstring 61 is connected to a pre-tensioned coil spring 63 and the other end is connected to the drawstring fixing point 23. Thus, the connecting drawstring 61 is connected between the second sliding member 33 and the screen assembly 2. The length of the connecting drawstring 61 can be changed by the movement of the second sliding member 33, so that the connecting drawstring 61 can maintain tension to pull the screen assembly 2, maintain good bending deformation of the screen assembly 2, and avoid twisting.

[0107] In practice, if Figure 4 and Figure 8 As shown, when the screen assembly 2 is in a convex state, the connecting rope 61 is stretched to produce elastic deformation and is in a tensioned state. The pulling force applied to the screen assembly 2 is greater than the deformation force of the outward arch of the screen assembly 2. The screen assembly 2 can be tightened to fit tightly against the installation shell 1 and embedded in the storage groove of the installation shell 1, preventing the screen assembly 2 from arching outward beyond the contour surface of the installation shell 1, thereby making the installation shell 1 flush with the surface of the screen assembly 2.

[0108] like Figure 6 and Figure 9 As shown, when the screen assembly 2 is in a straight state, the connecting rope 61 is in a natural state. At this time, the torque of the pre-tightening coil spring 63 is small, and it is only necessary to ensure that the connecting rope 61 does not sag. Therefore, the tension applied by the connecting rope 61 to the screen assembly 2 is very small, and the screen assembly 2 will not be deformed. The screen assembly 2 can remain straight. Figure 8 and Figure 9As shown, during the transformation of the screen assembly 2 from the flat state to the convex state, the two second sliding members 33 gradually approach the transmission gear 322, and the connecting rope 61 gradually stretches from the natural state, pulling the screen assembly 2 closer to the mounting housing 1, thereby preventing the second area 22 of the screen assembly 2 from arching outward beyond the front side of the mounting housing 1 when being bent and deformed ( Figure 8 The screen assembly 2 is in an outwardly arched state (marked in the middle), affecting the user experience. As the screen assembly 2 transitions from the convex state to the flat state, the two second sliding members 33 gradually move away from the transmission gear 322, and the connecting rope 61 gradually returns to its natural state. Driven by the pre-tensioned coil spring 63, it is then retracted into the rope pulley 62, preventing the connecting rope 61 from becoming loose and drooping.

[0109] like Figure 9 and Figure 10 As shown, during the process of the screen assembly 2 transforming from a flat state to a concave state, the two second sliding members 33 continue to move away from the transmission gear 322. At this time, the connecting rope 61 continues to be curled and recovered to the pulley 62 under the drive of the pre-tensioned coil spring 63, and the connecting rope 61 does not apply any pulling force to the screen assembly 2.

[0110] Therefore, by tightening the screen assembly 2 when the connecting rope 61 is in the convex state, it is possible to effectively prevent the screen assembly 2 from arching outward in the X direction and protruding from the front side of the mounting shell 1 when in the convex state, causing obvious step.

[0111] In actual design, Figure 5 As shown, a sliding bone position 68 can also be set on the second sliding member 33. At the same time, a pulley bone position 69 can be set on the pulley 62. When the pulley 62 on the left side rotates (clockwise rotation as shown in the figure) until the pulley 62 bone position contacts and presses against the sliding bone position 68, the sliding bone position 68 prevents the pulley 62 from continuing to rotate. At this time, the screen assembly 2 is in the initial state (convex state), and the connecting rope 61 is in a tensioned state, which can apply tension to the screen assembly 2. When the pulley 62 rotates (counterclockwise rotation as shown in the figure), the pulley 62 bone position is away from the sliding bone position 68 and can continue to rotate, so that the screen assembly 2 can be in a straight state or a concave state.

[0112] It can be understood that the rotation direction of the pulley 62 corresponds to the sliding direction of the second sliding member 33. Taking the pulley 62 on the left as an example, when the second sliding member 33 on the left moves close to the transmission gear 322, the pulley 62 on the left rotates clockwise, and when the second sliding member 33 on the left moves away from the transmission gear 322, the pulley 62 on the left rotates counterclockwise.

[0113] It should be noted that the clockwise and counterclockwise rotation of the rope pulley 62 can realize the contraction and extension of the connecting rope 61 to adapt to the movement of the second sliding member 33 and the screen assembly 2.

[0114] In some embodiments, the mounting bracket 13 is further provided with at least one rotatable roller 132 , and the connecting rope 61 is wound around the roller 132 .

[0115] That is, the mounting bracket 13 can be provided with two, three, four or even more rollers 132. By winding the connecting rope 61 around the rollers 132, the rollers 132 can rotate as the connecting rope 61 moves. The connecting rope 61 turns and moves around the rollers 132 to maintain the flatness of the connecting rope 61 and prevent the connecting rope 61 from twisting or entangled during movement, thereby maintaining the tension of the connecting rope 61.

[0116] Specifically, if Figure 1 、 Figure 4-Figure 7 As shown, two rollers 132 are respectively provided at the left and right ends of the mounting bracket 13. The two connecting ropes 61 on the left and right sides can be respectively wound around the two rollers 132 in turn and then connected to the screen assembly 2, effectively avoiding twisting or entanglement of the connecting ropes 61.

[0117] In some embodiments, the mounting bracket 13 is detachably mounted on the mounting housing 1 .

[0118] Specifically, the mounting bracket 13 can be installed on the mounting shell 1 by a detachable connection method such as a snap connection, a bolt connection, etc. This arrangement can facilitate the installation and disassembly of the mounting bracket 13 and the mounting shell 1. When the mounting bracket 13 or the mounting shell 1 is damaged and needs to be replaced and repaired, it is easy to remove, which is flexible and convenient.

[0119] In other embodiments, the mounting bracket 13 is detachably connected to the first area 21 via a connecting piece.

[0120] Specifically, the mounting bracket 13 and the first area 21, i.e., the middle area, of the screen assembly 2 can be detachably connected by bolts, screws and other connectors. This arrangement makes it convenient to install and disassemble the mounting bracket 13 and the screen assembly 2. When the mounting bracket 13 or the screen assembly 2 is damaged and needs to be replaced and repaired, it is easy to remove, which is flexible and convenient.

[0121] like Figure 1 As shown, three screw columns 70 are provided on the back side of the first area 21 of the screen assembly 2, that is, the surface facing the mounting shell 1, and three screw holes are provided at corresponding positions of the mounting shell 1. The screw columns 70 can be passed through the screw holes to be fixed to the mounting bracket 13 by screws, thereby realizing a fixed connection between the mounting bracket 13 and the first area 21.

[0122] In this way, when the screen assembly 2 is bent and deformed, the first area 21 can always remain stationary, thereby effectively fixing the screen assembly 2, ensuring that the screen assembly 2 does not rotate, and improving the deformation stability of the screen assembly 2.

[0123] In some embodiments, the sliding guide member 5 is constructed as a sliding guide rail, the first sliding member 41 is constructed as a sliding block, the first sliding member 41 is formed with a sliding groove 411, the sliding guide rail is passed through the sliding groove 411, and a sliding ball is provided between the inner wall of the sliding groove 411 and the sliding guide rail.

[0124] Specifically, if Figure 3 As shown, the sliding guide member 5 is constructed as a sliding guide rail, which extends in the left-right direction and can be fixedly mounted on the mounting housing 1 to maintain its stability. The first sliding member 41 is constructed as a sliding block, the center of which is concave to form a sliding groove 411 that is compatible with the shape and size of the sliding guide rail. The sliding guide rail can be inserted into the sliding groove 411, achieving smooth sliding of the sliding block on the sliding rail. Sliding balls are provided between the inner wall of the sliding groove 411 and the sliding guide rail. The sliding balls can reduce friction between the sliding block and the guide rail, improve sliding efficiency, and extend the service life of the sliding block and the sliding guide member 5.

[0125] In practice, when the sliding block slides on the sliding guide rail, the sliding balls roll in the sliding groove 411, converting the sliding friction into rolling friction, thereby greatly reducing friction and wear, improving the movement accuracy of the sliding block, and reducing the generation of noise.

[0126] In some embodiments, the rotation axis of the sliding link 42 and the first sliding member 41 coincides with the rotation axis of the rotating link 43 and the first sliding member 41 .

[0127] That is to say, the sliding link 42 and the rotating link 43 are both rotatably connected to the first sliding member 41 around the same rotation axis, so that the sliding link 42, the first sliding member 41 and the rotating link 43 can be connected by a rotating shaft to achieve relative movement of the sliding link 42, the first sliding member 41 and the rotating link 43.

[0128] Specifically, if Figure 3 As shown, rotating shafts are provided on the upper and lower end surfaces of the first sliding member 41, and a rotating shaft hole adapted to the rotating shaft is provided on the end of the sliding link 42 close to the first sliding member 41, and a rotating shaft hole adapted to the rotating shaft is also provided on the end of the rotating link 43 close to the first sliding member 41. Thus, the rotating shaft on the first sliding member 41 can pass through the rotating shaft holes of the sliding link 42 and the rotating link 43, so that the rotating axis of the sliding link 42 and the first sliding member 41 and the rotating axis of the rotating link 43 and the first sliding member 41 coincide with each other.

[0129] In this way, when the sliding link 42 and the rotating link 43 rotate around the same axis, that is, around the rotating shaft on the first sliding member 41, the movement of the sliding link 42 and the rotating link 43 can be accurately controlled, which helps to enhance the stability and reliability of the entire transmission structure 32.

[0130] In some embodiments, the sliding link 42 and the first sliding member 41 form two sets of first connection points 64 that are symmetrically distributed.

[0131] Specifically, if Figure 3 As shown, the sliding link 42 and the first sliding member 41 form two groups of first connection points 64 symmetrically distributed along the upper and lower sides, and the two groups of first connection points 64 correspond to the rotating shafts on the upper and lower end surfaces of the first sliding member 41. In this way, when assembling the sliding link 42 and the first sliding member 41, the first connection point 64 can form an assembly surface with the rotating shaft, that is, the first connection point 64 can be constructed as a rotating shaft hole, so that the rotating shaft can be inserted into the first connection point 64, thereby realizing the relative rotation between the sliding link 42 and the first sliding member 41. Setting two groups of first connection points 64 can increase the stability and flexibility of the structure, thereby making the bending deformation of the screen assembly 2 more stable and reliable.

[0132] In other embodiments, the rotating connecting rod 43 and the first sliding member 41 form two sets of symmetrically distributed second connection points 65 .

[0133] Specifically, if Figure 3 As shown, the rotating link 43 and the first sliding member 41 form two groups of second connection points 65 symmetrically distributed along the upper and lower sides, and the two groups of second connection points 65 correspond to the rotating shafts on the upper and lower end surfaces of the first sliding member 41. In this way, when assembling the rotating link 43 and the first sliding member 41, the second connection point 65 can form an assembly surface with the rotating shaft, that is, the second connection point 65 can be constructed as a rotating shaft hole, so that the rotating shaft can be inserted into the second connection point 65, thereby realizing the relative rotation between the rotating link 43 and the first sliding member 41. Setting two groups of second connection points 65 can increase the stability and flexibility of the structure, thereby making the bending deformation of the screen assembly 2 more stable and reliable.

[0134] In some embodiments, one of the second region 22 and the other end of the rotating link 43 is provided with a connecting shaft 66 and another rotating sleeve 67 , and the connecting shaft 66 is rotatably passed through the rotating sleeve 67 .

[0135] That is to say, a connecting shaft 66 can be set on the second area 22, and a rotating sleeve 67 can be set on the rotating link 43, or a rotating sleeve 67 can be set on the second area 22, and a connecting shaft 66 can be set on the rotating link 43, and the connecting shaft 66 can be passed through the rotating sleeve 67 and can rotate relative to the rotating sleeve 67, so that relative rotation between the rotating link 43 and the connecting shaft 66 can be achieved.

[0136] Specifically, if Figure 1As shown, a connecting shaft 66 is provided on the two second areas 22 at the left and right ends of the screen assembly 2, and a connecting sleeve is provided on the end of the rotating link 43 away from the first sliding member 41. The connecting shaft 66 can be passed through the rotating sleeve 67 and can be rotated relative to the rotating sleeve 67. In this way, when the rotating link 43 moves, it can rotatably pull or push the second area 22 forward or backward to bend and deform.

[0137] In some embodiments, an installation cavity 133 is formed in the installation shell 1, the screen assembly 2 is located outside the installation cavity 133, the driving assembly 3, the first sliding member 41 and the sliding link 42 are located in the installation cavity 133, one end of the rotating link 43 extends into the installation cavity 133 and is connected to the first sliding member 41, and the other end extends outside the installation cavity 133 and is connected to the screen assembly 2.

[0138] Specifically, if Figure 13 and Figure 14 As shown, the interior of the mounting housing 1 is hollow to form a mounting cavity 133. The drive assembly 3, the first sliding member 41, and the sliding link 42 can be installed in the mounting cavity 133 to prevent exposure to the external environment and damage. Among them, the rotating link 43 is partially installed in the mounting cavity 133. The end of the rotating link 43 near the first sliding member 41 extends into the mounting cavity 133 and is rotationally connected to the first sliding member 41. The other end is even outside the mounting cavity 133 and is rotationally connected to the screen assembly 2. Therefore, the rotating link 43 can transmit the movement in the mounting cavity 133 to the screen assembly 2, thereby achieving bending deformation of the second area 22 of the screen assembly 2.

[0139] In practice, when the screen assembly 2 is hit by external force, the external force is transmitted from the screen assembly 2 to the rotating link 43. The force applied to the first sliding member 41 by the rotating link 43 can be shared by the sliding link 42 and the sliding guide 5, so that the mounting shell 1 and the sliding guide rail bear most of the component force. Therefore, the component force transmitted by the sliding link 42 to the second sliding member 33 is very small, and the sliding link 42 and the second sliding member 33 are not easily damaged, so that the force state is good.

[0140] In some embodiments, the mounting shell 1 includes a front shell 11 and a rear shell 12 , which are detachably connected and jointly define a mounting cavity 133 , and the screen assembly 2 is mounted on a side of the front shell 11 facing away from the rear shell 12 .

[0141] Specifically, if Figure 1As shown, the mounting shell 1 includes a front shell 11 and a rear shell 12. The shapes of the front shell 11 and the rear shell 12 are the same as those of the screen assembly 2, and are constructed into a curved convex shape. The front shell 11 and the rear shell 12 are connected to define a mounting cavity 133. The front shell 11 and the rear shell 12 can be connected by detachable connection methods such as snap connection and bolt connection. In this way, it is convenient to install the drive assembly 3 and the transmission structure 32 in the mounting cavity 133, and when the front shell 11, the rear shell 12 or the internal components are damaged and need to be replaced and repaired, they can be easily disassembled and replaced, which is flexible and convenient.

[0142] Among them, a storage groove is provided on the side of the front shell 11 facing the screen assembly 2, and the shape and size of the storage groove are adapted to the shape and size of the screen assembly 2, so that the screen assembly 2 can be embedded in the storage groove to realize the storage of the screen assembly 2, that is, when the screen assembly 2 is in a convex state, it can be embedded in the storage groove, and when the screen assembly 2 is in a flat state or a concave state, the second areas 22 at both ends of the screen assembly 2 can be away from the front shell 11.

[0143] The present invention also provides a seat 100 .

[0144] The seat 100 according to the embodiment of the present invention includes a seat body 101 and a screen assembly 102 according to any one of the above embodiments, wherein the screen assembly 102 is mounted on the seat body 101 .

[0145] Specifically, if Figure 15 As shown, the seat 100 includes a seat body 101 , and a screen assembly 102 can be installed on the seat body 101 to meet the user's usage requirements.

[0146] In the screen assembly 102, the first area 21 of the screen assembly 2 is connected to the mounting shell 1 to fix the screen assembly 2, so that the first area 21 cannot be deformed. Through the cooperation of the driving assembly 3 and the connecting rod assembly 4, while ensuring the stability of the screen assembly 2, the second area 22 of the screen assembly 2 can be flexibly and stably bent and deformed, and is not prone to shaking or damage, thereby improving the user experience. In addition, the thickness of the entire screen assembly 102 is very small, does not require a lot of space, and has a compact structure, which is easy to arrange on the seat 100, reducing the space occupied by the seat 100 and increasing the use function of the seat 100. The screen assembly 102 is in good stress condition and is not prone to damage, thereby increasing the service life of the seat 100.

[0147] In some embodiments, a mounting groove 1011 is provided on the back of the seat body 101 , and at least a portion of the mounting shell 1 is mounted in the mounting groove 1011 .

[0148] Specifically, if Figure 15As shown, a mounting groove 1011 can be provided on the back of the seat body 101. The mounting groove 1011 has a certain depth, which can be adapted to the thickness of the screen assembly 102, and the mounting groove 1011 has the same shape as the mounting shell 1. The mounting shell 1 is a square shell with a certain curvature, and the mounting groove 1011 is constructed as a square groove, so that the mounting shell 1 can be installed in the mounting groove 1011, so that the screen assembly 102 is flush with the surface of the seat 100, and the overall coordination is consistent, thereby improving the aesthetics of the seat 100.

[0149] When the screen assembly 2 is not in use, the entire screen assembly 2 is embedded in the seat body 101, does not occupy the rear space, and does not affect the activities of the rear passengers. When the screen assembly 2 is in use, its convex state is located in the installation groove 1011, which is convenient for use. In the flat state and the concave state, the second area 22 at both ends of the screen assembly 2 extends outward from the installation groove 1011 for a certain distance to meet the user's usage needs.

[0150] The present invention also provides a functional device.

[0151] The functional device according to an embodiment of the present invention includes a device body and the screen assembly 102 of any one of the above embodiments, and the screen assembly 102 is installed on the device body.

[0152] Specifically, by installing the above-mentioned screen assembly 102 on the device body, the thickness of the device body can be reduced due to the small overall thickness of the screen assembly 102, which is conducive to achieving the lightness and thinness of the device body, and the bending deformation of the two ends of the screen component 2 is consistent, which can improve the performance of the device body.

[0153] Functional devices may be devices that may contain screens, such as computers, televisions, sofas, chairs, dashboards, etc. The screen assembly 102 of the present invention may be provided on these devices to meet user needs and improve user convenience.

[0154] The present invention also provides a vehicle.

[0155] The vehicle according to the embodiment of the present invention includes the screen assembly 102 according to any one of the above embodiments or includes the seat 100 according to any one of the above embodiments.

[0156] According to the vehicle of an embodiment of the present invention, the first area 21 of the screen assembly 2 is connected to the mounting shell 1 to fix the screen assembly 2, so that the first area 21 cannot be deformed. Through the cooperation of the driving assembly 3 and the connecting rod assembly 4, while ensuring the stability of the screen assembly 2, the second area 22 of the screen assembly 2 can be flexibly and stably bent and deformed, and is not prone to shaking or damage, thereby improving the user experience.
