[0111] The armrest body 100 has a screen mounting surface 110 with a storage groove 120. A posture adjustment component 2 is located on the armrest body 100 and includes a lead screw mechanism 300 and a linkage mechanism 400. The linkage mechanism 400 is rotatably connected to the lead screw mechanism 300. A display screen 200 has a display surface 210 and is mounted on the linkage mechanism 400. The lead screw mechanism 300 drives the linkage mechanism 400 to move along its axial direction, thereby causing the display screen 200 to flip between a retracted position and an extended position. When the display screen 200 is in the retracted position, it is retracted into the storage groove 120, and the display surface 210 is flush with the screen mounting surface 110. When the display screen 200 is in the extended position, at least a portion of the display screen 200 is outside the storage groove 120, and the edge of the display surface 210 adjacent to the screen mounting surface 110 forms a flipping edge 211, which is flush with the screen mounting surface 110.

[0112] The display screen 200 can extend to multiple positions, allowing it to hover at different positions and adjust the angle of its extension position according to user needs.

[0113] For example, the screen mounting surface 110 can be the upper surface of the armrest body 100. In this case, the rotation axis of the display screen 200 can extend along the left-right direction of the vehicle, and the rear edge of the display screen 200 along the front-rear direction of the vehicle forms a rotation edge 211, allowing the display screen 200 to rotate from front to back. Alternatively, the screen mounting surface 110 can be the side surface of the armrest body 100. In this case, the rotation axis of the display screen 200 can extend along the vertical direction of the vehicle, and the upper edge of the display screen 200 along the vertical direction of the vehicle forms a rotation edge 211, allowing the display screen 200 to rotate from bottom to top. Of course, the rotation axis and rotation direction of the display screen 200 can also be adjusted according to different actual needs.

[0114] According to an embodiment of the present invention, the armrest 1 of the seat has a screen mounting surface 110 on the armrest body 100, and the screen mounting surface 110 has a storage groove 120. The screen mounting surface 110 of the armrest body 100 can be the upper side of the armrest body 100. The storage groove 120 can store the display screen 200. The posture adjustment component 2 is provided on the armrest body 100. The posture adjustment component 2 includes a lead screw mechanism 300 and a linkage mechanism 400. The linkage mechanism 400 is rotatably connected to the lead screw mechanism 300. The display screen 200 has a display surface 210. The display screen 200 is mounted on the linkage mechanism 400. The lead screw mechanism 300 drives the linkage mechanism 400 to move along its axial direction, so as to drive the display screen 200 to flip between the storage position and the extension position.

[0115] In this way, the display screen 200 can switch between a retracted position and an extended position. When the user needs to view the display screen 200, the posture adjustment component 2 flips the display screen 200 to the extended position for easy viewing and improved viewing experience. When the user does not need to view the display screen 200, the posture adjustment component 2 flips the display screen 200 to the retracted position, which reduces the space occupied by the display screen 200 and increases the interior space. Furthermore, when the display screen 200 is retracted into the storage slot 120, the probability of collision with the display screen 200 is reduced when it is not in use, which helps protect the display screen 200 and prevents damage.

[0116] Furthermore, the display screen 200 is driven to rotate by the cooperation of the lead screw mechanism 300 and the linkage mechanism 400, making the transmission more stable. The lead screw mechanism 300 and the linkage mechanism 400 occupy less space, which makes it easier to install the posture adjustment component 2 inside the seat armrest 1. The overall volume of the seat armrest 1 will not increase or the increase will be small, which makes it easy to arrange.

[0117] It should be noted that the display screen 200 is not limited to the extended position. The display screen 200 can be suspended at any position between the retracted position and the extended position. When the display screen 200 is in the extended position, the angle between the screen mounting surface 110 and the display surface 210 can be no less than 60° and no more than 90°. When the display screen 200 is in the retracted position, the angle between the screen mounting surface 110 and the display surface 210 can be 0°.

[0118] In addition, when the display screen 200 is in the storage position, it is stored in the storage slot 120, with the display surface 210 flush with the screen mounting surface 110. This not only improves the storage effect of the storage slot 120 on the display screen 200, but also prevents the display screen 200 from protruding from the screen mounting surface 110, further reducing the chance of collision with the display screen 200 and better protecting it. The space occupied by the display screen 200 in the storage position is also minimized. Moreover, the transition between the display screen 200 and the screen mounting surface 110 is also smoother, avoiding any height difference between the two surfaces. This prevents dust from accumulating at the transition point, resulting in a cleaner appearance for the seat armrest 1.

[0119] Furthermore, when the display screen 200 is in the extended position, at least a portion of the display screen 200 is located outside the storage slot 120, and the edge of the display surface 210 adjacent to the screen mounting surface 110 forms a flip edge 211, which is flush with the screen mounting surface 110. Thus, when the display screen 200 flips from the storage position to the extended position, the flip edge 211 remains flush with the screen mounting surface 110. In other words, the position of the flip edge 211 of the display screen 200 remains unchanged during the flipping process, preventing the screen from moving forward or downward. This improves the rotational stability of the display screen 200, reduces the space required for movement, and makes it easier for the user to view the screen after it reaches the extended position, thus enhancing the viewing experience. Moreover, the gap between the display screen 200 and the armrest body 100 remains unchanged or changes very little, preventing dust from entering at the transition point and making the seat armrest 1 look cleaner, while also preventing hand pinching and improving the user experience.

[0120] Thus, the seat armrest 1 according to the present invention can not only store and raise the display screen 200, but also requires less space for the movement of the display screen 200, and has the advantages of small space occupation, easy viewing and flat appearance.

[0121] The posture adjustment component 2 for a display screen according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0122] The posture adjustment component 2 is installed on the component to be installed. The posture adjustment component 2 drives the display screen 200 to flip between the retracted position and the extended position relative to the component to be installed. When the display screen 200 is in the extended position, the edge of the display surface 210 adjacent to the armrest body 100 forms the flipping edge 211.

[0123] The attitude adjustment assembly 2 includes a lead screw mechanism 300 and a linkage mechanism 400. The linkage mechanism 400 includes a connecting rod 410 and a bracket 420. One end of the connecting rod 410 is rotatably connected to the lead screw mechanism 300. The display screen 200 is mounted on the bracket 420. The other end of the connecting rod 410 is rotatably connected to the bracket 420. The lead screw mechanism 300 drives one end of the connecting rod 410 to move, causing the other end of the connecting rod 410 to drive the bracket 420 to rotate, thereby driving the display screen 200 to rotate between a retracted position and an extended position.

[0124] The posture adjustment component 2 according to the embodiment of the present invention can not only store and raise the display screen 200, but also requires less space for the movement of the display screen 200, and has the advantages of small space occupation, easy viewing and flat appearance.

[0125] The following describes an embodiment of the seat armrest screen with reference to the accompanying drawings. The seat armrest screen includes a display screen 200 and a posture adjustment component 2 for the display screen according to the above embodiment of the present invention. The component to be installed is the armrest body 100. The posture adjustment component 2 is installed on the armrest body 100. The posture adjustment component 2 drives the display screen 200 to rotate relative to the armrest body 100 in a stowed position and an extended position.

[0126] According to the embodiments of the present invention, the seat armrest screen, by utilizing the posture adjustment component 2 for the display screen according to the above embodiments of the present invention, can not only store and raise the display screen 200, but also requires less space for the movement of the display screen 200, and has the advantages of small space occupation, easy viewing and flat appearance.

[0127] In some specific embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the axis of the lead screw mechanism 300 is set perpendicular to the flip axis of the display screen 200.

[0128] Specifically, the linkage mechanism 400 is connected to the lead screw mechanism 300, and the linkage mechanism 400 can move along the axial direction of the lead screw mechanism 300. When the linkage mechanism 400 moves towards one end of the axial direction of the lead screw mechanism 300, it can push one end of the display screen 200 upward, thereby causing the display screen 200 to flip from the retracted position to the extended position. When the linkage mechanism 400 moves towards the other end of the axial direction of the lead screw mechanism 300, it can drive one end of the display screen 200 downward, thereby causing the display screen 200 to flip from the extended position to the retracted position. Furthermore, this arrangement reduces the space required for the lead screw mechanism 300 and the linkage mechanism 400 during movement, thereby reducing the space required for the movement of the posture adjustment component 2, making it easier to assemble the posture adjustment component 2 into the handrail body 100, and further reducing the volume of the handrail body 100.

[0129] In some specific embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the flip axis of the display screen 200 coincides with the flip edge 211 of the display surface 210.

[0130] Therefore, the display screen 200 can be fixed to the attitude adjustment component 2 and driven to rotate by the lead screw mechanism 300 and the linkage mechanism 400. During the rotation process, the display screen 200 can rotate around the rotation edge 211 of the display surface 210. The position of the rotation edge 211 can remain unchanged. It can be understood that the rotation edge 211 of the display surface 210 is also a side of the upper surface of the display screen 200. This setting can avoid the gap change or height difference between the rotation edge 211 and the screen mounting surface 110 during the rotation process, thereby preventing the height of the display screen 200 from dropping, so that the rotation edge 211 and the screen mounting surface 110 can always remain flush, and the rotation stability of the display screen 200 is higher.

[0131] In some specific embodiments of the present invention, such as Figures 5-7 As shown, the linkage mechanism 400 includes a link 410 and a bracket 420.

[0132] One end of the connecting rod 410 is rotatably connected to the lead screw mechanism 300. The display screen 200 is mounted on the bracket 420. The other end of the connecting rod 410 is rotatably connected to the bracket 420. The lead screw mechanism 300 drives one end of the connecting rod 410 to move, causing the other end of the connecting rod 410 to drive the bracket 420 to rotate, thereby driving the display screen 200 to rotate between the retracted position and the extended position.

[0133] In other words, the display screen 200 in this embodiment of the invention can be rotated without rotating around a physical axis. Specifically, the display screen 200 can be fixedly connected to the bracket 420, and one end of the connecting rod 410 is connected to the lead screw mechanism 300 for transmission. When one end of the connecting rod 410 moves along the axial direction of the lead screw mechanism 300, the other end of the connecting rod 410 will also move radially relative to the lead screw mechanism 300. That is, the other end of the connecting rod 410 will move closer to or further away from the lead screw mechanism 300 along the radial direction of the lead screw mechanism 300. Thus, the bracket 420 can be moved closer to or further away from the lead screw mechanism 300 through the other end of the connecting rod 410, thereby driving the display screen 200 to flip between the retracted position and the extended position.

[0134] In some specific embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the rotation axes at both ends of the connecting rod 410 are arranged in parallel and perpendicular to the axial direction of the lead screw mechanism 300.

[0135] The rotation axes at both ends of the connecting rod 410 are parallel to the flip axis of the display screen 200, that is, the rotation axes at both ends of the connecting rod 410 are parallel to the flip edge 211 of the display surface 210. In this way, the connecting rod 410 itself will not twist, and the connecting rod 410 can drive the bracket 420 to rotate more stably, thereby improving the stability of the bracket 420 driving the display screen 200 to rotate, and making the rotation of the display screen 200 more stable.

[0136] In some specific embodiments of the present invention, such as Figures 6-10 As shown, the bracket 420 includes an arc-shaped plate segment 421. The bracket 420 drives the display screen 200 to rotate around the central axis of the arc-shaped plate segment 421. The central axis of the arc-shaped plate segment 421 coincides with the rotating edge 211 of the display surface 210.

[0137] By aligning the rotation axis of the arc-shaped plate segment 421 with the flip edge 211 of the display surface 210, the bracket 420 can rotate around the flip edge 211, thereby driving the display screen 200 to rotate around the flip edge 211 of the display surface 210. The position of the flip edge 211 will not change, thus preventing changes or minimal changes in the gap between the flip edge 211 and the screen mounting surface 110 of the seat armrest 1. This not only improves the dustproof and waterproof performance of the seat armrest 1, but also makes the connection between the display screen 200 and the screen mounting surface 110 more regular and aesthetically pleasing when the display screen 200 is extended.

[0138] In addition, it is understandable that the bracket 420 moves in an arc shape during rotation. By setting the arc-shaped plate segment 421, the area swept by the arc-shaped plate segment 421 during rotation can be smaller. This not only reduces the volume of the bracket 420 and the space required for the bracket 420 to rotate, but also avoids positional interference between the bracket 420 and other components, making the rotation of the bracket 420 more convenient.

[0139] Furthermore, such as Figures 6-10 As shown, the bracket 420 also includes a flat plate segment 422, which is connected to one side of the arc length direction of the arc plate segment 421. The display screen 200 is mounted on the flat plate segment 422. It can be understood that the display screen 200 is usually also flat. By setting the bracket 420 to connect the flat plate segment 422 and the display screen 200, the contact area between the flat plate segment 422 and the display screen 200 is larger, making it easier to connect. The connection between the flat plate segment 422 and the display screen 200 can be more stable.

[0140] In addition, the other end of the connecting rod 410 is rotatably connected to the connection between the flat plate segment 422 and the arc-shaped plate segment 421. This not only facilitates the connection between the connecting rod 410 and the bracket 420, but also allows the connecting rod 410 to be connected to the bracket 420 near the center, resulting in more even force distribution and further improving the stability of the attitude adjustment component 2 driving the display screen 200 to rotate.

[0141] In some specific embodiments of the present invention, such as Figure 6 As shown, when the display screen 200 is in the retracted position, the curved plate segment 421 is located inside the armrest body 100.

[0142] Specifically, the bracket 420 is connected to the side of the display screen 200 facing away from the display surface 210. When the display screen 200 is in the storage position, the display screen 200 will cover the posture adjustment component 2. That is, the posture adjustment component 2 will be located inside the armrest body 100, including the bracket 420. This not only allows the armrest body 100 to cover the posture adjustment component 2, making the appearance more beautiful, but also allows the armrest body 100 to protect the posture adjustment component 2, preventing users from accidentally bumping into the posture adjustment component 2 and damaging it. In addition, the user's riding experience is also better.

[0143] In some specific embodiments of the present invention, such as Figures 1-7 As shown, the seat armrest 1 also includes a cover plate 500.

[0144] The cover plate 500 is installed on the display screen 200. When the display screen 200 is in the retracted position, the cover plate 500 is located in the storage groove 120. When the display screen 200 is in the extended position, the cover plate 500 covers the part of the bracket 420 that extends out of the storage groove 120.

[0145] The cover plate 500 can be fixedly connected to the side of the display screen 200 facing away from the display surface 210. The cover plate 500 can rotate together with the display screen 200. When the display screen 200 is in the storage position, the cover plate 500 can also be located in the storage slot 120. The display screen 200 can then cover the cover plate 500, so that the armrest body 100 is not exposed, thus ensuring the overall neat appearance of the seat armrest 1. When the display screen 200 is in the extended position, the cover plate 500 can rotate and extend out of the storage slot 120 with the display screen 200. The cover plate 500 can also cover the part of the bracket 420 that is exposed in the storage slot 120. The user will not be able to directly see the bracket 420, making the appearance more aesthetically pleasing. It can also prevent the user from touching the bracket 420 and prevent the bracket 420 from pinching fingers when rotating, thus improving safety.

[0146] Alternatively, the cover plate 500 can also be constructed in an arc shape, which would reduce the space occupied by the cover plate 500 and make it easier to arrange.

[0147] In some specific embodiments of the present invention, such as Figures 5-7 As shown, the attitude adjustment component 2 also includes a slide rail 600.

[0148] The relative position of the slide rail 600 and the handrail body 100 is fixed. The slide rail 600 is constructed with an arc-shaped guide cavity 610. The arc-shaped plate segment 421 is slidably fitted into the arc-shaped guide cavity 610 to limit the rotation of the support 420 around the arc-shaped plate segment 421 around its central axis. The central axis of the arc-shaped guide cavity 610 coincides with the flip edge 211 of the display surface 210, and the arc-shaped guide cavity 610 limits the rotation of the support 420 around the flip edge 211 of the display surface 210.

[0149] In other words, the position of the slide rail 600 remains unchanged during the flipping process of the display screen 200. The arc-shaped guide cavity 610 of the slide rail 600 can guide the rotation of the bracket 420, making the rotation of the bracket 420 more stable. At the same time, the slide rail 600 can also play the role of fixing and supporting the bracket 420, making the overall structure of the attitude adjustment component 2 more stable and the rotation of the bracket 420 smoother, further improving the rotation stability of the display screen 200. The flipping edge 211 of the display surface 210 will not shift, and the fit between the display screen 200 and the screen mounting surface 110 is better during the flipping process.

[0150] Furthermore, such as Figure 5 and Figure 12 As shown, a damping element 430 is provided between the arc-shaped plate segment 421 and the inner wall of the guide cavity. The damping element 430 is used to apply damping force to the rotation of the bracket 420.

[0151] The damping component 430 can be a damping sleeve, spring, or damper, etc. By adding the damping component 430, the damping force between the bracket 420 and the inner wall of the arc-shaped guide cavity 610 can be increased, making the rotation of the bracket 420 more stable and preventing the bracket 420 from rotating rapidly. This allows the display screen 200 to rotate more smoothly, making it easier for the user to adjust the rotation position of the display screen 200. At the same time, the damping component 430 can absorb the instantaneous impact on the display screen 200 or the bracket 420, thereby preventing the bracket 420 from breaking or being damaged. In addition, the damping component 430 can also eliminate the gap between the bracket 420 and the slide rail 600 and the tooth gap in the attitude adjustment component 2, thereby preventing noise and vibration noise generated by the collision between the bracket 420 and the slide rail 600.

[0152] In some specific embodiments of the present invention, such as Figure 5 and Figure 12 As shown, damping elements 430 are distributed on both sides of the arc-shaped plate segment 421 along the axial direction.

[0153] In this way, there is damping force on both sides of the arc-shaped plate segment 421 and between the arc-shaped guide cavity 610, so that the damping force distribution between the arc-shaped plate segment 421 and the inner wall of the arc-shaped guide cavity 610 is more uniform, which further improves the rotational stability of the bracket 420, makes the display screen 200 flip more stably and reliably, avoids the display screen 200 from shaking, and provides a better viewing experience for the user.

[0154] For example, the damping element 430 can be a damping sleeve. The side of the damping element 430 facing the arc-shaped plate segment 421 can be provided with a mounting groove 431. The axial sides of the arc-shaped plate segment 421 are provided with inserts 426. The inserts 426 can be inserted into the mounting groove 431 of the damping element 430, thereby fixing the damping element 430 and the arc-shaped plate segment 421. The thickness of the damping element 430 can be greater than the thickness of the arc-shaped plate segment 421, and the thickness of the inserts 426 can be less than the thickness of the rest of the arc-shaped plate segment 421. The arc-shaped guide cavity 610 has a first arc-shaped guide wall 611 and a second arc-shaped guide wall 612. The first arc-shaped guide wall 611 and the second arc-shaped guide wall 612 are respectively provided on both sides of the arc-shaped plate segment 421 in the thickness direction. Each damping element 430 is in contact with the first arc-shaped guide wall 611 and the second arc-shaped guide wall 612 respectively.

[0155] This facilitates the assembly of the arc-shaped plate segment 421 and the damping element 430. Furthermore, after the damping element 430 contacts the first arc-shaped guide wall 611 and the second arc-shaped guide wall 612, the arc-shaped plate segment 421 will not contact the first arc-shaped guide wall 611 and the second arc-shaped guide wall 612, thus preventing wear between them. Simultaneously, it reduces the friction between the bracket 420 and the slide rail frame 600, facilitating the rotation of the bracket 420. Moreover, the arc-shaped guide cavity 610 can simultaneously guide both damping elements 430, reducing assembly errors between them and helping to minimize transmission errors between gears within the attitude adjustment assembly 2.

[0156] In some specific embodiments of the present invention, such as Figure 5 As shown, the attitude adjustment assembly 2 also includes a housing 700 and a drive mechanism 800.

[0157] The housing 700 is mounted on the armrest body 100, the drive mechanism 800 is mounted on the housing 700, the lead screw mechanism 300 is connected to the drive mechanism 800 for transmission, and the drive mechanism 800 drives the bracket 420 to rotate around the central axis of the arc plate segment 421 through the lead screw mechanism 300 and the connecting rod 410, so that the display screen 200 flips between the retracted position and the extended position.

[0158] Among them, the drive mechanism 800 can be a motor. The attitude adjustment component 2 can automatically drive the bracket 420 to rotate through the drive mechanism 800, thereby realizing the automatic flipping of the display screen 200. Compared with manually flipping the display screen 200, the operation is more convenient and faster, and the user experience is better.

[0159] Furthermore, all components of the attitude adjustment assembly 2 can be installed inside the housing 700, such as the drive mechanism 800, the lead screw mechanism 300, and the linkage mechanism 400. The bracket 420 can be located inside the housing 700 when the display screen 200 is in the retracted position, and can extend out of the housing 700 when the display screen 200 is in the extended position.

[0160] For example, the attitude adjustment component 2 may have a power-off reset function. When the vehicle is powered off, the attitude adjustment component 2 will cause the display screen 200 to automatically return to the horizontal state of the storage position.

[0161] In some specific embodiments of the present invention, such as Figure 5 As shown, the drive mechanism 800 is arranged on one radial side of the lead screw mechanism 300. Therefore, the drive mechanism 800 and the lead screw mechanism 300 can be arranged along the radial direction of the lead screw mechanism 300, and they can overlap in the axial direction of the lead screw mechanism 300. It is understood that the axial length of the lead screw mechanism 300 will be greater than its radial length. This arrangement avoids an excessively large overall axial length for the drive mechanism 800 and the lead screw mechanism 300, thereby reducing the space occupied by the attitude adjustment component 2. The attitude adjustment component 2 can be smaller and easier to install.

[0162] In some specific embodiments of the present invention, such as Figures 5-7 , Figure 13 As shown, the lead screw mechanism 300 includes a lead screw 310 and a first nut 320.

[0163] The lead screw 310 is connected to the drive mechanism 800. The first nut 320 is sleeved on the lead screw 310 and threadedly engaged with it. One end of the connecting rod 410 is rotatably connected to the first nut 320. Thus, when the drive mechanism 800 drives the lead screw 310 to rotate, the threaded engagement between the first nut 320 and the lead screw 310 converts the rotation of the lead screw 310 into linear movement of the first nut 320. Furthermore, the drive mechanism 800 can drive the lead screw 310 to rotate forward and backward, causing the first nut 320 to move back and forth along the axial direction of the lead screw 310. The end of the connecting rod 410 connected to the display screen 200 can rotate relative to the end of the connecting rod 410 connected to the nut, thereby driving the display screen 200 to flip between a retracted position and an extended position.

[0164] Furthermore, such as Figure 13As shown, one end of the first nut 320 and the connecting rod 410 is provided with a first connecting rod shaft 321, and the other end is provided with a first shaft hole 413. The first connecting rod shaft 321 is rotatably fitted into the first shaft hole 413.

[0165] For example, the first nut 320 may have a first connecting rod shaft 321 and the connecting rod 410 may have a first shaft hole 413. The first connecting rod shaft 321 can extend into the first shaft hole 413, allowing the connecting rod 410 to rotate relative to the first nut 320. When the drive mechanism 800 drives the lead screw 310 to rotate, the first nut 320 moves axially along the lead screw 310. The connecting rod 410, while following the axial movement of the first nut 320 along the lead screw 310, can rotate relative to the first nut 320. This allows the end of the connecting rod 410 away from the first nut 320 to push the bracket 420 to rotate, thus achieving the flipping of the display screen 200. Furthermore, this configuration simplifies the connection structure between the first nut 320 and the connecting rod 410, ensuring a secure connection and preventing separation, while also allowing the connecting rod 410 to rotate relative to the first nut 320.

[0166] In some specific embodiments of the present invention, such as Figure 13 As shown, one end of the connecting rod 410 is constructed with a first connecting plate 411 and a second connecting plate 412 spaced apart.

[0167] The first connecting plate 411 and the second connecting plate 412 are respectively disposed on the radially opposite sides of the first nut 320. The first connecting plate 411 and the second connecting plate 412 are respectively provided with the first shaft hole 413. The radially opposite sides of the first nut 320 are respectively provided with the first connecting rod shaft 321 inserted into the corresponding first shaft hole 413.

[0168] In this way, the first connecting plate 411 and the second connecting plate 412 can respectively abut against the radially opposite sides of the first nut 320. The first connecting plate 411 abuts against one radial side of the first nut 320, thereby preventing the connecting rod 410 from shifting towards the second connecting plate 412. The second connecting plate 412 abuts against the other radial side of the first nut 320, thereby preventing the connecting rod 410 from shifting towards the first connecting plate 411. This makes the fit between the first connecting rod shaft 321 and the first shaft hole 413 more stable, preventing the connecting rod 410 from disengaging from the first nut 320, and making the connection between the connecting rod 410 and the first nut 320 more stable.

[0169] Additionally, it should be noted that the first connecting plate 411 and the second connecting plate 412 have a certain elastic deformation capability, so that when the connecting rod 410 and the first nut 320 are assembled, the first connecting plate 411 and the second connecting plate 412 can be moved to increase the distance between the first connecting plate 411 and the second connecting plate 412, making it easier to insert the first connecting rod shaft 321 into the first shaft hole 413 of the first connecting plate 411 and the first shaft hole 413 of the second connecting plate 412 respectively.

[0170] In some specific embodiments of the present invention, such as Figure 13 As shown, a bearing 330 is provided between the outer peripheral surface of the first connecting rod shaft 321 and the inner peripheral surface of the first shaft hole 413. The bearing 330 can be a ball bearing. By adding the bearing 330, the friction between the first connecting rod shaft 321 and the first shaft hole 413 can be reduced, resulting in less resistance when the connecting rod 410 rotates relative to the first nut 320. This not only reduces the wear of the connecting rod 410 and the first nut 320, but also makes the rotation of the connecting rod 410 easier, further improving the stability of the connecting rod 410's rotation. The attitude adjustment component 2 can then drive the display screen 200 to rotate more smoothly.

[0171] In some specific embodiments of the present invention, such as Figures 5-7 , Figure 13 As shown, the lead screw mechanism 300 also includes a second nut 340 and an elastic element 350.

[0172] The second nut 340 is sleeved on the lead screw 310 and threadedly engaged with the lead screw 310, and the elastic element 350 is sleeved on the lead screw 310 and abuts against the first nut 320 and the second nut 340.

[0173] Understandably, during the production process, in order to ensure that the first nut 320 can be fitted onto the lead screw 310 and to avoid excessive frictional resistance between the first nut 320 and the lead screw 310, there usually needs to be a small gap in the threaded fit between the first nut 320 and the lead screw 310. However, by adding a second nut 340, and with the first nut 320 and the second nut 340 being stopped by the elastic element 350, the elastic force of the elastic element 350 can ensure that the internal threads of the first nut 320 and the second nut 340 are always tightly pressed against the threads on the lead screw 310, thereby eliminating the transmission gap between the lead screw 310 and the first nut 320. This prevents the first nut 320 from wobbling in the radial and axial directions relative to the lead screw 310, and more effectively prevents the display screen 200 from wobbling. The fixing and flipping of the display screen 200 are also more stable.

[0174] In some specific embodiments of the present invention, such as Figure 13 As shown, the second nut 340 includes a nut body 341 and a receiving ring 342.

[0175] The nut body 341 is sleeved on the lead screw 310 and threaded with the lead screw 310. The elastic element 350 abuts between the first nut 320 and the nut body 341. The receiving ring 342 is connected to the side of the nut body 341 facing the first nut 320 and surrounds the elastic element 350 and the first nut 320.

[0176] By providing a receiving ring 342 on the second nut 340, the receiving ring 342 can accommodate the elastic element 350 and the first nut 320. That is, the first nut 320 and the elastic element 350 can both be located inside the second nut 340. In this way, the second nut 340 can cover the elastic element 350 and the first nut 320 to protect the elastic element 350 and the first nut 320 and prevent the elastic element 350 from colliding with other components and failing.

[0177] In addition, the periphery of the receiving ring 342 is provided with a notch 343 extending along the axial direction of the receiving ring 342. The first connecting rod shaft 321 is movably fitted into the notch 343. In this way, the second nut 340 can use the notch 343 to avoid positional interference between the receiving ring 342 and the first connecting rod shaft 321.

[0178] Furthermore, after the first connecting rod shaft 321 extends into the notch 343, the notch 343 can abut against the radially opposite sides of the first connecting rod shaft 321 on opposite sides of the circumferential direction along the receiving ring 342. When the drive mechanism 800 drives the lead screw 310 to rotate, causing the first nut 320 to move closer to the second nut 340, the first nut 320 can push the second nut 340 to move together through the elastic element 350, thereby realizing the flipping of the display screen 200 from the retracted position to the extended position (or the flipping of the display screen 200 from the extended position to the retracted position). When the drive mechanism 800 drives the lead screw... When the first nut 320 moves away from the second nut 340 by rotating 310, the first connecting rod shaft 321 is stopped on the side wall of the notch 343 on its radially opposite sides. Therefore, the first connecting rod shaft 321 and the second nut 340 cannot rotate relative to each other. In other words, the first nut 320 and the second nut 340 will not rotate relative to each other. As a result, the second nut 340 rotates with the first nut 320 relative to the lead screw 310, thereby enabling the display screen 200 to flip from the extended position to the retracted position (or the display screen 200 to flip from the retracted position to the extended position).

[0179] In some specific embodiments of the present invention, such as Figure 5 As shown, the drive mechanism 800 is a motor, and the attitude adjustment component 2 also includes a speed reduction and torque amplification mechanism 900. The lead screw 310 is connected to the drive mechanism 800 through the speed reduction and torque amplification mechanism 900. The speed reduction and torque amplification mechanism 900 includes a first-stage worm 910, a first-stage gear 920, a second-stage worm 930, and a second-stage gear 940.

[0180] The first-stage worm 910 is mounted on the motor shaft of the motor and is driven to rotate by the motor shaft. The first-stage gear 920 is mounted on the housing 700 and meshes with the first-stage worm 910. The second-stage worm 930 is mounted on the housing 700 and rotates synchronously with the first-stage gear 920. The second-stage gear 940 is mounted on the lead screw 310 and rotates synchronously with the gear shaft. The second-stage gear 940 meshes with the second-stage worm 930.

[0181] Thus, when the user needs to rotate the display screen 200, the drive mechanism 800 can be activated. The drive mechanism 800 can drive the first-stage worm gear 910 to rotate, and the power can be transmitted sequentially through the first-stage worm gear 910, the first-stage gear 920, the second-stage worm gear 930, and the second-stage gear 940 to the lead screw mechanism 300. Then, through the lead screw mechanism 300 and the linkage mechanism 400, the display screen 200 is rotated. Furthermore, through the gear meshing of the speed reduction and torque amplification mechanism 900, the rotational speed transmitted from the drive mechanism 800 to the lead screw mechanism 300 can be effectively reduced, thereby increasing the torque transmitted from the drive mechanism 800 to the lead screw mechanism 300, so that the rotation of the display screen 200 is more stable.

[0182] Furthermore, such as Figures 5-7 As shown, the central axis of the first-stage worm 910 coincides with the central axis of the motor shaft; the central axis of the first-stage gear 920 coincides with and is perpendicular to the central axis of the second-stage worm 930; and the central axis of the second-stage gear 940 coincides with and is perpendicular to the central axis of the lead screw 310. This arrangement results in a more compact structural layout for the drive mechanism 800, the first-stage worm 910, the first-stage gear 920, the second-stage worm 930, and the second-stage gear 940, accommodating less space and facilitating their arrangement.

[0183] In some specific embodiments of the present invention, such as Figure 13 As shown, the lead screw 310 includes a threaded section 311 and a connecting section 312 connected to each other. The cross-sectional area of ​​the connecting section 312 is larger than that of the threaded section 311. The first nut 320 is fitted onto the threaded section 311 and threadedly engaged with it. In this way, the end of the connecting section 312 facing the threaded section 311 can stop and limit the first nut 320, preventing it from moving to the connecting section 312 or even disengaging from the lead screw 310, thus making the engagement between the first nut 320 and the lead screw 310 more stable and reliable.

[0184] Furthermore, one of the outer peripheral surface of the connecting section 312 and the inner peripheral surface of the secondary gear 940 is provided with a transmission rib 313 and the other is provided with a transmission groove 941. The transmission rib 313 is inserted into the transmission groove 941 so that the secondary gear 940 rotates synchronously with the gear shaft.

[0185] For example, the outer circumferential surface of the connecting section 312 may be provided with a transmission rib 313 and the inner circumferential surface of the secondary gear 940 may be provided with a transmission groove 941. In this way, when the drive mechanism 800 is running, the secondary gear 940 can transmit power to the lead screw 310 through the cooperation of the transmission groove 941 and the transmission rib 313, so that the lead screw 310 can rotate synchronously with the secondary gear 940. Furthermore, through the transmission cooperation of the transmission groove 941 and the transmission rib 313, the power transmission between the secondary gear 940 and the lead screw 310 is more stable and reliable.

[0186] Furthermore, such as Figure 13 As shown, there are multiple transmission ribs 313 arranged at intervals along the circumference of the connecting section 312, and multiple transmission grooves 941 arranged at intervals along the circumference of the secondary gear 940. The multiple transmission ribs 313 are inserted into the multiple transmission grooves 941 in a one-to-one correspondence.

[0187] In this way, when the secondary gear 940 transmits power to the lead screw 310, the circumferential force on the secondary gear 940 and the lead screw 310 is more uniform, making the power transmission between the secondary gear 940 and the lead screw 310 more stable and reliable, and more effectively avoiding the failure of power transmission between the secondary gear 940 and the lead screw 310. For example, when one of the multiple transmission ribs 313 and multiple transmission grooves 941 is damaged and fails, the cooperation of the remaining multiple transmission ribs 313 and multiple transmission grooves 941 can still ensure the power transmission between the secondary gear 940 and the lead screw 310.

[0188] In some specific embodiments of the present invention, such as Figure 13 As shown, the transmission rib 313 is provided on the outer peripheral surface of the connecting section 312. One end of the transmission rib 313 facing away from the threaded section 311 has a guide portion. The height of the guide portion gradually decreases in the direction away from the threaded section 311. In this way, when assembling the connecting section 312 and the secondary gear 940, the guide portion can guide the assembly of the transmission rib 313 and the transmission groove 941, which helps to simplify the assembly steps of the connecting section 312 and the secondary gear 940 and makes the assembly more convenient.

[0189] In some specific embodiments of the present invention, such as Figure 11 As shown, the housing 700 is constructed with a first limiting surface 710 and a second limiting surface 720.

[0190] When the display screen 200 flips from the extended position to the retracted position, the bracket 420 abuts against the first limiting surface 710; when the display screen 200 flips from the retracted position to the extended position, the bracket 420 abuts against the second limiting surface 720. This ensures that the flipping range of the display screen 200 is limited to the retracted position to the extended position, preventing damage from excessive flipping of the display screen 200.

[0191] In some specific embodiments of the present invention, such as Figure 11 As shown, the housing 700 has a first limiting rib 730 and a second limiting rib 740, which are spaced apart. The connecting rod 410 is located between the first limiting rib 730 and the second limiting rib 740. The first limiting rib 730 has a first limiting surface 710 and a second limiting surface 720, and the second limiting rib 740 has a first limiting surface 710 and a second limiting surface 720.

[0192] Specifically, the first limiting rib 730 and the second limiting rib 740 are located on opposite radial sides of the lead screw 310. When the display screen 200 is in the retracted position, the bracket 420 can simultaneously abut against the first limiting surface 710 of the first limiting rib 730 and the first limiting surface 710 of the second limiting rib 740. When the display screen 200 is flipped to the extended position, the bracket 420 can simultaneously abut against the second limiting surface 720 of the first limiting rib 730 and the second limiting surface 720 of the second limiting rib 740, so as to limit the display screen 200 in the retracted position and the extended position.

[0193] Furthermore, by setting two limiting ribs to limit the bracket 420, it is possible to prevent the bracket 420 from shifting or shaking after it comes into contact with a single limiting rib. This helps to improve the limiting effect of the bracket 420 and ensures that the display screen 200 remains stable in both the retracted and extended positions.

[0194] In some specific embodiments of the present invention, such as Figure 12 As shown, the bracket 420 is constructed with a lug 423, the lug 423 is provided with a second shaft hole 424, the other end of the connecting rod 410 is provided with a third shaft hole 414, and the other end of the connecting rod 410 is rotatably connected to the bracket 420 through a second connecting rod shaft 440 that is engaged with the second shaft hole 424 and the third shaft hole 414. Thus, the bracket 420 can be pushed to rotate along the rotation axis of the arc plate segment 421 by the rotation of the connecting rod 410, so that the display screen 200 can be flipped along the flip edge 211 of the display surface 210.

[0195] In addition, when the display screen 200 is flipped from the extended position to the retracted position, the lug 423 abuts against the first limiting surface 710. In this way, the lug 423 can be used to connect the bracket 420 and the connecting rod 410 to realize the relative rotation of the bracket 420 and the connecting rod 410, and the lug 423 can also be used to limit the bracket 420 to realize the limitation of the display screen 200 in the retracted position. Therefore, there is no need to set up an additional structure for limiting with the first limiting surface 710, which helps to simplify the structure of the bracket 420.

[0196] Furthermore, such as Figure 12As shown, the bracket 420 also includes a limiting folding plate 425. The limiting folding plate 425 is connected to the side of the arc length direction of the arc-shaped plate segment 421 away from the display screen 200. When the display screen 200 is flipped from the storage position to the extended position, the limiting folding plate 425 abuts against the first limiting surface 710, thereby limiting the display screen 200 when it is in the extended position, making the positioning more accurate and reliable and preventing the display screen 200 from rotating excessively.

[0197] In some specific embodiments of the present invention, such as Figures 5-7 As shown, the housing 700 includes an upper cover 750, a lower cover 760, a mounting bracket 780, and a slide rail bracket 600.

[0198] The upper cover 750 and the lower cover 760 are connected to each other and together define the mounting cavity 770. The mounting bracket 780 and the circuit board are mounted on the lower cover 760 and located in the mounting cavity 770. The drive mechanism 800 and the lead screw mechanism 300 are mounted on the mounting bracket 780. The slide rail bracket 600 is mounted on the mounting bracket 780. The slide rail bracket 600 and the lower cover 760 are respectively located on opposite sides of the mounting bracket 780. The arc-shaped plate segment 421 cooperates with the slide rail to limit the bracket 420 to rotate around the central axis of the arc-shaped plate segment 421.

[0199] In this way, the upper cover 750 and the lower cover 760 can cover the drive mechanism 800, the lead screw mechanism 300, the linkage mechanism 400, the mounting bracket 780, and the slide rail bracket 600, making the appearance of the attitude adjustment assembly 2 more aesthetically pleasing and preventing users from directly touching the drive mechanism 800, the lead screw mechanism 300, and the linkage mechanism 400, thus improving safety. At the same time, the attitude adjustment assembly 2 can also use the mounting bracket 780 to fix the drive mechanism 800, the lead screw mechanism 300, and the slide rail bracket 600, making the connection and fixation of each component of the attitude adjustment assembly 2 more stable. By fixing multiple parts with one mounting bracket 780, assembly errors are reduced, which has a better effect on controlling the center distance of the gears and can appropriately reduce the noise of the gear transmission.

[0200] In some specific embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the seat armrest 1 also includes a gesture collection device 950.

[0201] The gesture acquisition device 950 is connected to the posture adjustment component 2. The posture adjustment component 2 drives the display screen 200 to switch between the retracted position and the extended position based on the gesture information acquired by the gesture acquisition device 950.

[0202] For example, the gesture acquisition device 950 can be an infrared sensing module. In this way, the gesture acquisition device 950 can collect the user's gesture information. The user can use different gesture information to control the posture adjustment component 2 to retract and extend, and then control the display screen 200 to retract, extend, or flip to different angles. For example, when the user raises their hand, the display screen 200 can rotate upwards following the gesture; when the hand lowers, the display screen 200 can rotate downwards following the gesture. This further simplifies the user's operation, eliminating the need for the user to switch the position of the display screen 200 by touching it or pressing buttons. The operation is more convenient and faster, which helps to improve the user's operating experience.

[0203] In some specific embodiments of the present invention, the seat armrest 1 further includes a fingerprint collection device. The fingerprint collection device may be a touchscreen.

[0204] The fingerprint acquisition device is connected to the posture adjustment component 2. The posture adjustment component 2 drives the display screen 200 to switch between the retracted position and the extended position based on the fingerprint information acquired by the fingerprint acquisition device.

[0205] Specifically, when different users save the information of the flip angle of the display screen 200, they can register their fingerprints through the fingerprint collection device. When the user uses the display screen 200 again, after pressing their finger on the fingerprint collection device, the fingerprint collection device can control the posture adjustment component 2 to drive the display screen 200 to the corresponding position according to the fingerprint information. In other words, the display screen 200 can have multiple memory positions, and each memory position corresponds to different fingerprint information. When different users use the display screen 200, the display screen 200 can flip to the flip angle corresponding to the user's fingerprint information, further improving the user experience.

[0206] Of course, the same user can also register multiple fingerprints. Multiple fingerprints can correspond to different flip angles of the display screen 200. When the user presses the fingerprint collection device with different fingers, the fingerprint collection device can control the posture adjustment component 2 to operate according to the collected fingerprint information, so as to drive the display screen 200 to flip to the position corresponding to the fingerprint. In this way, the same user can also save multiple flip angles of the display screen 200, which can better meet the usage needs of different users.

[0207] The following is a brief description of the steps by which the attitude adjustment component 2 drives the display screen 200 to flip:

[0208] First, the user starts the drive mechanism 800, which drives the first-stage worm gear 910 to rotate. The first-stage worm gear 910 transmits power sequentially to the first-stage gear 920, the second-stage worm gear 930, and the second-stage gear 940, causing the second-stage gear 940 to rotate.

[0209] Then, the secondary gear 940 transmits power to the lead screw 310 and drives the lead screw 310 to rotate synchronously, and the first nut 320 moves along the axial direction of the lead screw 310;

[0210] Finally, the connecting rod 410 moves along the axis of the lead screw 310 following the first nut 320 and rotates relative to the first nut 320. While moving, the connecting rod 410 pushes the bracket 420 to rotate, and the display screen 200 rotates with the bracket 420, thereby enabling the display screen 200 to be flipped.

[0211] The assembly steps of attitude adjustment component 2 are briefly described below:

[0212] First, connect the first-stage worm gear 910 and the drive mechanism 800. After connecting the drive mechanism 800 and the mounting bracket 780, fix them with two screws.

[0213] Then, the secondary gear 940 is fitted onto the lead screw 310, and the first nut 320, the elastic element 350 and the second nut 340 are fitted onto the lead screw 310 in sequence. At this time, the elastic element 350 needs to be in a certain amount of compression. Then, the first nut 320, the elastic element 350 and the second nut 340 are screwed into the lead screw 310 together.

[0214] Next, the connecting rod 410 is fixed to the first nut 320 by two bearings 330, and then connected to the mounting bracket 780. The lower cover 760, the first-stage gear 920 and the second-stage worm gear 930 are then fixed to the mounting bracket 780 in sequence.

[0215] Then, the two damping sleeves are respectively fitted onto the opposite sides of the bracket 420 along the axial direction and installed into the slide rail bracket 600, and then fixed to the mounting bracket 780 with screws.

[0216] Finally, fix the upper cover 750 and the lower cover 760, and then connect the bracket 420 and the cover plate 500 to the display screen 200 in sequence.
