The rotating mechanism 800 drives the linkage mechanism 360 to move along its circumference, so as to drive the display screen 200 to flip between the storage position and the extended position.

[0112] When the display screen 200 is in the retracted position, it is stored in the storage slot 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 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.

[0113] 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.

[0114] 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 the rotation edge, 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 the rotation edge, 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.

[0115] 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 a storage groove 120 on the screen mounting surface 110. 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 disposed on the armrest body 100. The display screen 200 has a display surface 210. The display screen 200 is mounted on the posture adjustment component 2. The posture adjustment component 2 drives the display screen 200 to flip between the storage position and the extended position.

[0116] 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.

[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, making the seat armrest 1 look cleaner.

[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 accumulation at the transition point and maintaining a cleaner appearance for the seat armrest 1, while also preventing hand pinching and improving the user experience.

[0120] Thus, the seat armrest 1 according to the present invention can store and raise the display screen 200, and the movement of the display screen 200 requires less space, which has the advantages of small space occupation, easy viewing and flat appearance.

[0121] The following description, with reference to the accompanying drawings, describes a posture adjustment assembly 2 for a display screen according to an embodiment of the present invention. The posture adjustment assembly 2 drives the display screen 200 to rotate relative to the armrest body 100 between a retracted position and an extended position.

[0122] The attitude adjustment assembly 2 includes a rotation mechanism 800 and a linkage mechanism 360. The linkage mechanism 360 includes a link 890 and a bracket 300. One end of the link 890 is rotatably connected to the rotation mechanism 800. The display screen 200 is mounted on the bracket 300. The other end of the link 890 is rotatably connected to the bracket 300. The rotation mechanism 800 drives one end of the link 890 to rotate, causing the other end of the link 890 to rotate the bracket 300, thereby driving the display screen 200 to rotate between a retracted position and an extended position. The bracket 300 includes an arc-shaped plate segment 310. The bracket 300 drives the display screen 200 to rotate around the central axis of the arc-shaped plate segment 310.

[0123] The posture adjustment component 2 for the display screen according to the embodiment of the present invention can accommodate and raise the display screen 200, and the movement of the display screen 200 requires less space, which has the advantages of small space occupation, easy viewing and flat appearance.

[0124] The following description, with reference to the accompanying drawings, describes a seat armrest screen according to an embodiment of the present invention. 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 retracted position and an extended position.

[0125] According to the embodiments of the present invention, the armrest screen of the seat can be used to store and raise the display screen 200 by utilizing the posture adjustment component 2 for the display screen according to the above embodiments of the present invention. Moreover, the movement of the display screen 200 requires less space, and has the advantages of small space occupation, easy viewing and flat appearance.

[0126] According to some specific embodiments of the present invention, as shown in Figures 1, 3, and 4, the axial direction of the rotating mechanism 800 is arranged parallel to the flip axis of the display screen 200. This reduces the size of the posture adjustment component 2 in the direction perpendicular to the flip axis of the display screen 200, facilitating miniaturization of the posture adjustment component 2 and making it suitable for use with a smaller armrest body 100 in the direction perpendicular to the flip axis of the display screen 200.

[0127] In some specific embodiments of the present invention, as shown in Figures 1, 3 and 4, the flip axis of the display screen 200 coincides with the flip edge 211 of the display surface 210.

[0128] Specifically, the display screen 200 can be fixed to the attitude adjustment component 2 and driven to flip through the configuration adjustment component. During the flipping process, the display screen 200 can flip around the flipping edge 211 of the display surface 210. The position of the flipping edge 211 can remain unchanged. It can be understood that the flipping edge 211 of the display surface 210 is also a side of the upper surface of the display screen 200. This setting can prevent the gap change or height difference between the flipping edge 211 and the screen mounting surface 110 during the flipping process, thereby preventing the height of the display screen 200 from dropping, so that the flipping edge 211 and the screen mounting surface 110 can remain flush, and the rotation stability of the display screen 200 is higher.

[0129] According to some specific embodiments of the present invention, as shown in Figures 4 and 8, the linkage mechanism 360 includes a link 890 and a support 300.

[0130] One end of the connecting rod 890 is rotatably connected to the rotating mechanism 800. The display screen 200 is mounted on the bracket 300. The other end of the connecting rod 890 is rotatably connected to the bracket 300. The rotating mechanism 800 drives one end of the connecting rod 890 to rotate, causing the other end of the connecting rod 890 to rotate the bracket 300, thereby driving the display screen 200 to rotate between the retracted position and the extended position.

[0131] By setting the bracket 300, the connection area between the attitude adjustment component 2 and the display screen 300 can be increased, ensuring the reliability of the connection between the attitude adjustment component 2 and the display screen 300. By setting the connecting rod 890, the power and displacement between the bracket 300 and the rotating mechanism 800 can be realized, thereby enabling the bracket 300 to drive the display screen 200 to switch between the retracted position and the extended position.

[0132] According to some specific embodiments of the present invention, as shown in Figures 4 and 8, the rotation axes at both ends of the connecting rod 890 are arranged in parallel and parallel to the axial direction of the rotating mechanism 800. This reduces the size of the posture adjustment component 2 in the direction of the flip axis of the vertical display screen 200, facilitating the miniaturization of the posture adjustment component 2 and making it suitable for use with a smaller armrest body 100 in the direction of the flip axis of the vertical display screen 200.

[0133] According to some specific embodiments of the present invention, as shown in Figures 4, 8 and 9, the bracket 300 includes an arc-shaped plate segment 310. The bracket 300 drives the display screen 200 to rotate around the central axis of the arc-shaped plate segment 310. The central axis of the arc-shaped plate segment 310 coincides with the rotating edge 211 of the display surface 210.

[0134] In other words, the display screen 200 in this embodiment of the invention does not need to rotate around a solid axis, and the rotation axis of the bracket 300 is set to coincide with the flip edge 211 of the display surface 210. In this way, when the bracket 300 rotates, it can drive 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, thereby avoiding 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 when the display screen 200 is in the extended position, resulting in a more aesthetically pleasing appearance.

[0135] In addition, it is understandable that the bracket 300 moves in an arc shape during rotation. By setting the arc-shaped plate segment 310, the area swept by the arc-shaped plate segment 310 during rotation can be smaller. This not only reduces the volume of the bracket 300 and the space required for the bracket 300 to rotate, but also avoids positional interference between the bracket 300 and other components, making the rotation of the bracket 300 more convenient.

[0136] According to some specific embodiments of the present invention, as shown in Figures 4, 8, and 9, the bracket 300 further includes a flat plate segment 350, which is connected to one side of the arcuate plate segment 310 along its arc length direction. The display screen 200 is mounted on the flat plate segment 350, and one end of the connecting rod 890 is rotatably connected to the connection between the flat plate segment 350 and the arcuate plate segment 310. This improves the stability of the bracket 300 during movement, thereby increasing the stability of the display screen 200 moving between its retracted and extended positions, and reducing the probability of damage to the display screen 200.

[0137] According to some specific embodiments of the present invention, as shown in FIG5, when the display screen 200 is in the storage position, the arc-shaped plate segment 310 is located inside the armrest body 100.

[0138] Specifically, the bracket 300 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 300. This not only allows the armrest body 100 to cover the posture adjustment component 2, making the appearance more aesthetically pleasing, but also protects the posture adjustment component 2, preventing users from accidentally bumping into it and damaging it, and also improving the user's riding experience.

[0139] In some specific embodiments of the present invention, as shown in Figures 2 and 3, 4 and 5, the seat armrest 1 also includes a cover plate 400.

[0140] The cover plate 400 is installed on the display screen 200. When the display screen 200 is in the retracted position, the cover plate 400 is located in the storage groove 120. When the display screen 200 is in the extended position, the cover plate 400 covers the part of the bracket 300 that extends out of the storage groove 120.

[0141] The cover plate 400 can be fixedly installed on the display screen 200, meaning the cover plate 400 can rotate together with the display screen 200. The cover plate 400 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 cover plate 400 can also be located in the storage slot 120, thus the display screen 200 can cover the cover plate 400, preventing the armrest body 100 from being exposed, ensuring the overall neat appearance of the seat armrest 1. When the display screen 200 is in the extended position, the cover plate 400 can rotate and extend out of the storage slot 120 along with the display screen 200, and the cover plate 400 can cover the part of the bracket 300 exposed in the storage slot 120. The user will not be able to directly see the bracket 300, making the appearance more aesthetically pleasing and preventing the user from touching the bracket 300, thus preventing the bracket 300 from pinching fingers when rotating, and improving safety.

[0142] Alternatively, the cover plate 400 can be constructed as an arc shape that adapts to the arc-shaped plate segment 310 of the support 300, so that the space occupied by the cover plate 400 can be smaller and easier to arrange.

[0143] In some specific embodiments of the present invention, as shown in Figures 5, 6 and 8, the attitude adjustment component 2 further includes a slide rail 500.

[0144] The relative position of the slide rail frame 500 and the handrail body 100 is fixed. The slide rail frame 500 is constructed with an arc-shaped guide cavity 510. The arc-shaped plate segment 310 of the support 300 is slidably fitted into the arc-shaped guide cavity 510 to limit the rotation of the support 300 around the central axis of the arc-shaped plate segment 310. The central axis of the arc-shaped plate segment 310 coincides with the flip edge 211 of the display surface 210, that is, the arc-shaped guide cavity 510 of the slide rail frame 500 limits the rotation of the support 300 around the arc-shaped plate segment 310 around the flip edge 211 of the display surface 210.

[0145] In other words, the position of the slide rail 500 remains unchanged during the flipping process of the display screen 200. The arc-shaped guide cavity 510 of the slide rail 500 can guide the rotation of the bracket 300. At the same time, the slide rail 500 can also play a role in fixing and supporting the bracket 300, so that the overall structure of the attitude adjustment component 2 is more stable, the rotation of the bracket 300 is more stable, and the rotation stability of the display screen 200 is further improved. 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.

[0146] Furthermore, as shown in Figures 5, 6, and 8, a damping element 320 is provided between the arc-shaped plate segment 310 and the inner wall of the arc-shaped guide cavity 510. The damping element 320 can be a damping sleeve, spring, or damper, etc., and is used to apply damping force to the rotation of the bracket 300. By adding the damping element 320, the damping force between the bracket 300 and the arc-shaped guide cavity 510 can be increased, making the rotation of the bracket 300 more stable and preventing the bracket 300 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 element 320 can absorb the instantaneous impact on the display screen 200 or the bracket 300, thereby preventing the bracket 300 from breaking or being damaged. In addition, the damping element 320 can also eliminate the gap between the bracket 300 and the slide rail 500 and the tooth gap in the attitude adjustment component 2, thereby preventing noise and vibration noise generated by collisions between the bracket 300 and the slide rail 500.

[0147] Furthermore, as shown in Figures 5, 6, and 8, the damping elements 320 are distributed on both axial sides of the arc-shaped plate segment 310. This ensures that there is damping force between both axial sides of the arc-shaped plate segment 310 and the arc-shaped guide cavity 510, resulting in a more uniform distribution of damping force between the inner walls of the arc-shaped plate segment 310 and the arc-shaped guide cavity 510. This further improves the rotational stability of the bracket 300, making the rotation of the display screen 200 more stable and reliable, preventing the display screen 200 from shaking, and providing a better user experience.

[0148] For example, as shown in Figures 5, 6, and 8, the damping element 320 can be a damping sleeve. The side of the damping element 320 facing the arc-shaped plate segment 310 can be provided with a mounting groove 321. The arc-shaped plate segment 310 has inserts 312 on both axial sides. The inserts 312 can be inserted into the mounting groove 321 of the damping element 320, thereby fixing the damping element 320 and the arc-shaped plate segment 310. The thickness of the damping element 320 can be greater than the thickness of the arc-shaped plate segment 310, and the thickness of the inserts 312 can be less than the thickness of the rest of the arc-shaped plate segment 310. The arc-shaped guide cavity 210 has a first arc-shaped guide wall 511 and a second arc-shaped guide wall 512. The first arc-shaped guide wall 511 and the second arc-shaped guide wall 512 are respectively provided on both sides of the arc-shaped plate segment 310 in the thickness direction. Each damping element 320 is in contact with the first arc-shaped guide wall 511 and the second arc-shaped guide wall 512 respectively.

[0149] This facilitates the assembly of the arc-shaped plate segment 310 and the damping component 320. Moreover, after the damping component 320 contacts the inner wall of the arc-shaped guide cavity 510, the arc-shaped plate segment 310 will not contact the inner wall of the arc-shaped guide cavity 510, thereby avoiding wear between the arc-shaped plate segment 310 and the arc-shaped guide cavity 510. At the same time, it can reduce the friction between the bracket 300 and the slide rail 500, so as to facilitate the rotation of the bracket 300.

[0150] Furthermore, the arc-shaped guide cavity 510 can guide the two damping elements 320 simultaneously, reducing the assembly error between the two damping elements 320 and helping to reduce the transmission error between the gears in the attitude adjustment assembly 2.

[0151] According to some specific embodiments of the present invention, as shown in FIG5, FIG6 and FIG8, the attitude adjustment assembly 2 further includes a housing 600 and a drive mechanism 700.

[0152] The housing 600 is installed on the armrest body 100, the drive mechanism 700 is installed on the housing 600, and the rotating mechanism 800 is connected to the drive mechanism 700 and the bracket 300 respectively. The drive mechanism 700 drives the bracket 300 to rotate around the central axis of the arc plate segment 310 through the rotating mechanism 800, so as to drive the display screen 200 to flip between the retracted position and the extended position.

[0153] Among them, the drive mechanism 700 can be a motor. The attitude adjustment component 2 can automatically drive the bracket 300 to rotate through the drive mechanism 700, 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.

[0154] Furthermore, all components of the attitude adjustment assembly 2 can be installed inside the housing 600, such as the drive mechanism 700, the rotation mechanism 800, and the bracket 300. The bracket 300 can be located inside the housing 600 when the display screen 200 is in the retracted position, and can extend out of the housing 600 when the display screen 200 is in the extended position.

[0155] For example, the attitude adjustment component 2 may have a power-off reset function. When the vehicle is powered off, the transmission mechanism 800 will drive the display screen 200 to automatically return to the horizontal position of the storage position.

[0156] According to some specific embodiments of the present invention, as shown in Figures 5, 6 and 8, the drive mechanism 700 is arranged at one end of the axial direction of the rotation mechanism 800. This reduces the size of the posture adjustment component 2 in the direction of the rotation axis of the vertical display screen 200, facilitating the miniaturization of the posture adjustment component 2, and thus making it suitable for use with a smaller armrest body 100 in the direction of the rotation axis of the vertical display screen 200.

[0157] According to some specific embodiments of the present invention, as shown in Figures 4 and 8, the rotating mechanism 800 includes a connecting rod bushing 810.

[0158] The connecting rod bushing 810 is provided with a first shaft hole 811, and one end of the connecting rod 890 is provided with a second shaft hole 891. One end of the connecting rod 890 is rotatably connected to the connecting rod bushing 810 through a connecting rod shaft 892 that is fitted into the first shaft hole 811 and the second shaft hole 891.

[0159] In this way, the posture adjustment component 2 can transmit power to the connecting rod sleeve 810 through the drive mechanism 700 to drive the connecting rod sleeve 810 to rotate. The connecting rod sleeve 810 then transmits power to the arc plate segment 310 through the connecting rod 890, which can drive the bracket 300 to rotate, so as to realize the flip extension and storage of the display screen 200.

[0160] According to some specific embodiments of the present invention, as shown in Figures 4 and 8, the outer peripheral surface of the connecting rod bushing 810 is provided with first lugs 812 spaced apart along the axial direction of the connecting rod bushing 810. Each first lug 812 is provided with a first shaft hole 811, and one end of the connecting rod 890 is located between adjacent first lugs 812. By placing one end of the connecting rod 890 between adjacent first lugs 812, not only can the transmission connection between the connecting rod bushing 810 and the connecting rod 890 be realized, but the first lugs 812 can also position the connecting rod 890 in the axial direction of the connecting rod bushing, ensuring the relative position between the connecting rod bushing 810 and the connecting rod 890.

[0161] In some specific embodiments of the present invention, as shown in Figures 4 and 8, the rotating mechanism 800 further includes a transmission shaft 820 and a fixing member 840.

[0162] The connecting rod bushing 810 is connected to the drive mechanism 700 via the drive shaft 820. The outer circumferential surface of the drive shaft 820 is provided with an annular piece 830. The connecting rod bushing 810 is sleeved on the drive shaft 820 and rotates synchronously with the drive shaft 820. The fixing member 840 is installed on the drive shaft 820. The connecting rod bushing 810 is constrained in the axial direction of the drive shaft 820 between the annular piece 830 and the fixing member 840.

[0163] In other words, the ring plate 830 and the fixing member 840 are located at the two axial ends of the connecting rod bushing 810, respectively. This allows the ring plate 830 and the fixing member 840 to axially limit the connecting rod bushing 810, thereby fixing the relative position of the connecting rod bushing 810 and the transmission shaft 820 in the axial direction of the transmission shaft 820. The connecting rod bushing 810 will not wobble, which helps to make the power transmission between the connecting rod bushing 810 and the bracket 300 more stable.

[0164] Furthermore, as shown in Figures 4 and 8, the rotating mechanism 800 also includes an elastic element 850, which is sleeved on the transmission shaft 820 and abuts against the connecting rod bushing 810 and the fixing element 840.

[0165] For example, the elastic element 850 can be a spring, which is sleeved on the drive shaft 820 and located between the connecting rod sleeve 810 and the fixing member 840. After the transmission mechanism 800 is assembled, the elastic element 850 can be in a compressed state, so that the fixing member 840 can press the connecting rod sleeve 810 through the elastic element 850, thereby pressing the connecting rod sleeve 810 between the fixing member 840 and the ring plate 830, further improving the stability of the position fixation of the connecting rod sleeve 810. The connecting rod sleeve 810 is less likely to wobble along the axial direction of the drive shaft 820, and the fit between the connecting rod sleeve 810 and the bracket 300 is more stable. The transmission mechanism 800 can stably transmit power to the bracket 300, thereby driving the display screen 200 to rotate stably.

[0166] In some specific embodiments of the present invention, as shown in Figures 4 and 8, the rotating mechanism 800 further includes a washer 860. The washer 860 is sleeved on the transmission shaft 820 and located between the elastic member 850 and the connecting rod bushing 810. In this way, the elastic member 850 can abut against the connecting rod bushing 810 through the washer 860. By adding the washer 860, it is easier for the elastic member 850 to abut against the elastic member 850. The abutment between the elastic member 850 and the washer 860 is more stable, and the contact area between the washer 860 and the connecting rod bushing 810 is larger, so that the elastic member 850 can reliably press the connecting rod bushing 810 against the ring piece 830, further improving the axial fixing effect of the connecting rod bushing 810.

[0167] In some specific embodiments of the present invention, as shown in Figures 4 and 8, the rotating mechanism 800 further includes a transmission block 870 and a friction plate 880.

[0168] The transmission block 870 is sleeved on the transmission shaft 820. The transmission block 870 is located between the connecting rod bushing 810 and the ring plate 830 and rotates synchronously with the transmission shaft 820. The friction plate 880 is located between the transmission block 870 and the connecting rod bushing 810. The transmission block 870 transmits the rotation of the transmission shaft 820 to the connecting rod bushing 810 through the friction plate 880.

[0169] It should be noted that the friction between the friction plate 880 and the transmission block 870, as well as the friction between the friction plate 880 and the connecting rod bushing 810, are both greater than the driving force required for the display screen 200 to flip. Thus, when the display screen 200 is actively driven to flip by the drive mechanism 700, the transmission block 870 can transmit power to the connecting rod bushing 810 through the friction plate 880, thereby driving the connecting rod bushing 810 to rotate, so as to realize the flipping of the display screen 200.

[0170] When an external force causes the display screen 200 to tend to flip, such as when a user manually moves the display screen 200 or accidentally bumps it, if the external force is greater than the friction between the friction plate 880 and the transmission block 870, or greater than the friction between the friction plate 880 and the connecting rod bushing 810, then the connecting rod bushing 810 and the friction plate 880 or the friction plate 880 and the transmission block 870 will rotate relative to each other, which will cause the display screen 200 to be pushed to flip by the external force. This setting can prevent the display screen 200 from breaking or cracking due to excessive external force after the transmission mechanism 800 locks the display screen 200.

[0171] In some specific embodiments of the present invention, as shown in Figures 4 and 8, one of the ring plate 830 and the transmission block 870 is provided with a slot 831 and the other is provided with a tooth 871. The tooth 871 is inserted into the slot 831 so that the transmission block 870 rotates synchronously with the transmission shaft 820.

[0172] For example, the ring plate 830 may be provided with a groove 831 and the transmission block 870 may be provided with a tooth 871. In this way, when the ring plate 830 rotates synchronously with the transmission shaft 820, the power can be transmitted to the transmission block 870 through the cooperation of the groove 831 and the tooth 871, so that the transmission block 870 can rotate synchronously with the transmission shaft 820. Furthermore, through the transmission cooperation of the groove 831 and the tooth 871, the power transmission between the ring plate 830 and the transmission block 870 is more stable and reliable.

[0173] Furthermore, as shown in Figures 4 and 8, multiple slots 831 are spaced apart circumferentially along the ring plate 830, and multiple teeth 871 are spaced apart circumferentially along the transmission block 870. Each tooth 871 is inserted into a corresponding slot 831. In this way, when the ring plate 830 transmits power to the transmission block 870, the circumferential force on both the ring plate 830 and the transmission block 870 is more evenly distributed, making the power transmission between them more stable and reliable. This more effectively prevents power transmission failure between the ring plate 830 and the transmission block 870. For example, if one of the teeth 871 or slots 831 fails, the remaining teeth 871 and slots 831 can still ensure power transmission between the ring plate 830 and the transmission block 870.

[0174] In some other specific embodiments of the present invention, the rotating mechanism 800 further includes a transmission block 870 and a clutch device (not shown in the figure).

[0175] The transmission block 870 is sleeved on the transmission shaft 820. The transmission block 870 is located between the connecting rod bushing 810 and the ring plate 830 and rotates synchronously with the transmission shaft 820. The clutch device is located between the transmission block 870 and the connecting rod bushing 810. The clutch device controls whether power is transmitted between the transmission block 870 and the connecting rod bushing 810.

[0176] Specifically, when the clutch is engaged, it can transmit power, meaning the transmission block 870 can transmit power to the connecting rod sleeve 810 through the clutch, thereby driving the connecting rod sleeve 810 to rotate, so that the drive mechanism 700 can drive the display screen 200 to flip. When the clutch is disengaged, the power transmission is interrupted, meaning there is no power transmission between the transmission block 870 and the connecting rod sleeve 810. When the display screen 200 is manually flipped, the rotational force of the display screen 200 will not be transmitted to the transmission block 870 through the clutch, thus protecting the drive mechanism 700.

[0177] In some specific embodiments of the present invention, as shown in Figures 4 and 8, the outer peripheral surface of the transmission shaft 820 is provided with a groove 821, and the fixing member 840 is a retaining ring. The retaining ring is engaged in the groove 821. Thus, the groove 821 can pre-position the retaining ring, and after the retaining ring is engaged in the groove 821, it can limit the axial movement of the connecting rod bushing 810.

[0178] In some specific embodiments of the present invention, as shown in Figures 4 and 8, the drive mechanism 700 is a motor, and the attitude adjustment component 2 further includes a speed reduction and torque amplification mechanism 900. The transmission shaft 820 is connected to the drive mechanism 700 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.

[0179] 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 600 and meshes with the first-stage worm 910. The second-stage worm 930 is mounted on the housing 600 and rotates synchronously with the first-stage gear 920. The second-stage gear 940 is mounted on the transmission shaft 820 and rotates synchronously with the transmission shaft 820. The second-stage gear 940 meshes with the second-stage worm 930.

[0180] Thus, when the user needs to rotate the display screen 200, the drive mechanism 700 can be activated. The drive mechanism 700 can drive the first-stage worm gear 910 to rotate, and the power can be transmitted to the rotation mechanism 800 in sequence through the first-stage worm gear 910, the first-stage gear 920, the second-stage worm gear 930, and the second-stage gear 940. The rotation mechanism 800 then drives the display screen 200 to rotate. Furthermore, through the gear meshing of the speed reduction and torque amplification mechanism 900, the rotational speed transmitted from the drive mechanism 700 to the rotation mechanism 800 can be effectively reduced, thereby increasing the torque transmitted from the drive mechanism 700 to the rotation mechanism 800, so that the rotation of the display screen 200 is more stable.

[0181] Furthermore, 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 transmission shaft 820. This results in a more compact structural layout for the drive mechanism 700, 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.

[0182] In some specific embodiments of the present invention, as shown in Figures 4 and 8, one of the outer peripheral surface of the transmission shaft 820 and the inner peripheral surface of the secondary gear 940 is provided with a transmission rib 822 and the other is provided with a transmission groove 941. The transmission rib 822 is inserted into the transmission groove 941 so that the secondary gear 940 rotates synchronously with the transmission shaft 820.

[0183] For example, the outer circumferential surface of the drive shaft 820 may be provided with a transmission rib 822 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 700 is running, the secondary gear 940 can transmit power to the drive shaft 820 through the cooperation of the transmission groove 941 and the transmission rib 822, so that the drive shaft 820 and the secondary gear 940 can rotate synchronously. Furthermore, through the transmission cooperation of the transmission groove 941 and the transmission rib 822, the power transmission between the secondary gear 940 and the drive shaft 820 is more stable and reliable.

[0184] Furthermore, as shown in Figures 4 and 8, there are multiple transmission ribs 822 spaced apart circumferentially along the transmission shaft 820, and multiple transmission grooves 941 spaced apart circumferentially along the secondary gear 940, with the multiple transmission ribs 822 inserted into the multiple transmission grooves 941 in a one-to-one correspondence.

[0185] In this way, when the secondary gear 940 transmits power to the drive shaft 820, the circumferential force on the secondary gear 940 and the drive shaft 820 is more uniform, making the power transmission between the secondary gear 940 and the drive shaft 820 more stable and reliable, and more effectively avoiding the failure of power transmission between the secondary gear 940 and the drive shaft 820. For example, when one of the multiple transmission ribs 822 and multiple transmission grooves 941 is damaged and fails, the cooperation of the remaining multiple transmission ribs 822 and multiple transmission grooves 941 can still ensure the power transmission between the secondary gear 940 and the drive shaft 820.

[0186] In some specific embodiments of the present invention, as shown in Figures 4 and 8, a transmission rib 822 is provided on the outer peripheral surface of the transmission shaft 820. One end of the transmission rib 822 facing away from the connecting rod bushing 810 has a guide portion 823. The height of the guide portion 823 gradually decreases in the direction away from the connecting rod bushing 810. In this way, when assembling the transmission shaft 820 and the secondary gear 940, the guide portion 823 can guide the assembly of the transmission rib 822 and the transmission groove 941, which helps to simplify the assembly steps of the transmission shaft 820 and the secondary gear 940 and makes the assembly more convenient.

[0187] In some specific embodiments of the present invention, as shown in Figures 5 and 6, and Figures 9-10, the housing 600 is constructed with a first limiting surface 601 and a second limiting surface 602. When the display screen 200 is flipped from the extended position to the retracted position, the bracket 600 abuts against the first limiting surface 601. When the display screen 200 is flipped from the retracted position to the extended position, the bracket 600 abuts against the second limiting surface 602.

[0188] In this way, the rotation range of the display screen 200 can be determined to be from the retracted position to the extended position, thus avoiding damage to the display screen 200 due to excessive rotation.

[0189] According to some specific embodiments of the present invention, as shown in Figures 5 and 6, and Figures 9-10, the housing 600 has a first limiting rib 650 and a second limiting rib 660, which are spaced apart. A connecting rod 890 is located between the first limiting rib 650 and the second limiting rib 660, and the first limiting rib 650 and the second limiting rib 660 form a first limiting surface 601. The first limiting rib 650 and the second limiting rib 660 can be provided in the mounting bracket 640 described below, with the first limiting rib 650 and the second limiting rib 660 provided on the side of the mounting bracket 640 near the display screen 200.

[0190] By setting the first limiting rib 650 and the second limiting rib 660, it can be ensured that the stopping force on the bracket 600 in its axial direction is uniform, and the bracket 600 will not deflect. Furthermore, the first limiting rib 650 and the second limiting rib 660 are spaced apart, leaving sufficient space for the movement of the connecting rod 890, and preventing interference between the first limiting surface 601 and the connecting rod 890.

[0191] According to some specific embodiments of the present invention, as shown in Figures 5 and 6, and Figures 9-10, the bracket 300 is constructed with a limiting block 340. When the display screen 200 is flipped from the extended position to the retracted position, the limiting block 340 abuts against the first limiting surface 601. The limiting block 340 is disposed on the side of the flat plate segment 350 facing away from the display screen 200. By setting the limiting block 340 to cooperate with the first limiting surface 601, the reliability of the limiting can be improved.

[0192] Furthermore, the bracket 300 also includes a limiting folding plate 330, which is connected to the side of the arc-length section 310 away from the display screen 200. When the display screen 200 is flipped from the retracted position to the extended position, the limiting folding plate 330 abuts against the second limiting surface 602. This makes the positioning more reliable.

[0193] According to some specific embodiments of the present invention, as shown in Figures 4 and 8, the housing 600 includes an upper cover 610, a lower cover 620, a mounting bracket 640, and a slide rail bracket 500.

[0194] The upper cover 610 and the lower cover 620 are connected to each other and together define the mounting cavity 630. The mounting bracket 640 is mounted on the lower cover 620 and located in the mounting cavity 630. The drive mechanism 700 and the transmission mechanism 800 are mounted on the mounting bracket 640. The slide rail bracket 500 is mounted on the mounting bracket 640. The slide rail bracket 500 and the lower cover 620 are respectively located on opposite sides of the mounting bracket 640. The arc-shaped plate segment 310 cooperates with the slide rail bracket 500 to limit the bracket 300 to rotate around the arc-shaped plate segment 310 around its central axis.

[0195] In this way, the upper cover 610 and the lower cover 620 can cover the drive mechanism 700, the rotating mechanism 800, the mounting bracket 640, and the slide rail bracket 500, making the appearance of the attitude adjustment assembly 2 more aesthetically pleasing and preventing users from directly touching the drive mechanism 700 or the transmission mechanism 800, thus improving safety. At the same time, the attitude adjustment assembly 2 can also use the mounting bracket 640 to fix the drive mechanism 700, the transmission mechanism 800, and the slide rail bracket 500, making the connection and fixation of each component of the attitude adjustment assembly 2 more stable. By fixing multiple parts with one mounting bracket 640, 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.

[0196] The lower cover 620 and the mounting bracket 640 are equipped with a circuit board 950, which is connected to the drive mechanism 700 and is used to control the operation of the drive mechanism 700.

[0197] In some specific embodiments of the present invention, as shown in Figures 2 and 3, the seat armrest 1 also includes a gesture collection device 980.

[0198] The gesture acquisition device 980 is connected to the posture adjustment component 2. The posture adjustment component 2 drives the display screen 200 to flip between the retracted position and the extended position based on the gesture information acquired by the gesture acquisition device 980.

[0199] For example, the gesture acquisition device 980 can be an infrared sensing module. In this way, the gesture acquisition device 980 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.

[0200] In some specific embodiments of the present invention, as shown in Figures 5 and 6, the seat armrest 1 further includes a fingerprint collection device 970. The fingerprint collection device 970 can be a touchscreen.

[0201] For example, the fingerprint acquisition device 970 can be exposed from the armrest body 100 to collect the user's fingerprint information. The fingerprint acquisition device 970 is connected to the posture adjustment component 2, which drives the display screen 200 to flip between the retracted position and the extended position based on the fingerprint information collected by the fingerprint acquisition device 970.

[0202] 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 970. When the user uses the display screen 200 again, after pressing their finger on the fingerprint collection device 970, the fingerprint collection device 970 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.

[0203] 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 970 with different fingers, the fingerprint collection device 970 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.

[0204] The following is a brief description of the steps by which the attitude adjustment component 2 drives the display screen 200 to flip:

[0205] First, the user starts the drive mechanism 700, 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.

[0206] Then, the secondary gear 940 transmits power to the drive shaft 820 and drives the drive shaft 820 to rotate synchronously, and the ring plate 830 rotates synchronously with the drive shaft 820.

[0207] Finally, the ring plate 830 drives the connecting rod bushing 810 to rotate through the friction plate 880. The connecting rod bushing 810 can drive the bracket 300 to rotate, and the display screen 200 follows the bracket 300 to rotate, thereby realizing the flipping of the display screen 200.

[0208] The assembly steps of attitude adjustment component 2 are briefly described below:

[0209] First, connect the drive mechanism 700 and the mounting bracket 640, and then secure them with two screws;

[0210] Then, after the secondary gear 940 is fitted onto the drive shaft 820, the transmission block 870, friction plate 880, connecting rod bushing 810, washer 860, and elastic element 850 are sequentially fitted onto the drive shaft 820. Then, the fixing element 840 is snapped into the groove 821 of the drive shaft 820 to form the rotating mechanism 800. The rotating mechanism 800 and the mounting bracket 640 are then fixed.

[0211] Next, the lower cover 620, the first-stage gear 920, and the second-stage gear 940 are fixed to the mounting bracket 640 respectively;

[0212] Then, the two damping sleeves are respectively fitted onto the opposite sides of the bracket 300 along the axial direction and installed into the slide rail bracket 500, and then fixed to the mounting bracket 640 with screws.

[0213] Finally, fix the upper cover 610 and the lower cover 620, and then connect the bracket 300 and the cover plate 400 to the display screen 200 in sequence.

[0214] The following description, with reference to the accompanying drawings, describes a seat according to an embodiment of the present invention, the seat including a seat armrest 1 according to the above embodiment of the present invention.

[0215] According to an embodiment of the present invention, the seat can accommodate and raise the display screen 200 by utilizing the seat armrest 1 of the above embodiment of the present invention. Moreover, the movement of the display screen 200 requires less space, and it has the advantages of small space occupation, easy viewing and flat appearance.
