[0111] The armrest body 100 has a screen mounting surface 110, the screen mounting surface 110 is provided with a storage groove 120, the posture adjustment component 2 is arranged on the armrest body 100, the display screen 200 has a display surface 210, the posture adjustment component 2 includes a rotating mechanism 800 and a connecting rod mechanism 360, the connecting rod mechanism 360 is rotatably connected to the rotating mechanism 800, the display screen 200 is installed on the connecting rod mechanism 360, the rotating mechanism 800 drives the connecting rod mechanism 360 to move along its circumferential direction 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 storage 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 located outside the storage slot 120, and the edge of the display surface 210 adjacent to the screen mounting surface 110 constitutes a flip edge 211, and the flip edge 211 is flush with the screen mounting surface 110.

[0113] The display screen 200 may have multiple extended positions, so that the display screen 200 can hover at different extended positions, and the angle of the extended position of the display screen 200 can be adjusted according to user needs.

[0114] For example, the screen installation surface 110 may be the upper surface of the armrest body 100, in which case the flip axis of the display screen 200 may extend along the left-right direction of the vehicle, and the rear edge of the display screen 200 along the front-back direction of the vehicle constitutes a flip edge, and the display screen 200 flips from front to back. Alternatively, the screen installation surface 110 may be the side surface of the armrest body 100, in which case the flip axis of the display screen 200 may extend along the up-down direction of the vehicle, and the upper edge of the display screen 200 along the up-down direction of the vehicle constitutes a flip edge, and the display screen 200 flips from bottom to top. Of course, the flip axis and flip direction of the display screen 200 may also be adjusted according to different actual needs.

[0115] According to the chair armrest 1 of the embodiment of the present invention, a screen mounting surface 110 is provided on the armrest body 100, and a storage groove 120 is provided on the screen mounting surface 110, wherein the screen mounting surface 110 of the armrest body 100 can be the upper side surface of the armrest body 100, and the storage groove 120 can store the display screen 200, and the posture adjustment component 2 is provided on the armrest body 100, and the display screen 200 has a display surface 210, and the display screen 200 is installed on the posture adjustment component 2, and 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 be switched between the storage position and the extended position. When the user needs to view the display screen 200, the display screen 200 can be flipped to the extended position through the posture adjustment component 2 to facilitate user viewing and improve the user viewing experience. When the user does not need to view the display screen 200, the display screen 200 can be flipped to the storage position through the posture adjustment component 2. This can reduce the space occupied by the display screen 200 to increase the space inside the vehicle. After the display screen 200 is stored in the storage slot 120, the probability of colliding with the display screen 200 can be reduced when the display screen 200 is not in use, which is beneficial to protecting the display screen 200 and avoiding damage to the display screen 200.

[0117] It should be noted that the display screen 200 is not only able to hover in the extended position, but can hover at any position between the storage 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 may be no less than 60° and no more than 90°. When the display screen 200 is in the storage position, the angle between the screen mounting surface 110 and the display surface 210 may be 0°.

[0118] In addition, when the display screen 200 is in the storage position, it is stored in the storage groove 120, and the display surface 210 is flush with the screen mounting surface 110. In this way, not only can the storage effect of the storage groove 120 on the display screen 200 be improved, the display screen 200 will not protrude from the screen mounting surface 110, further reducing the probability of collision with the display screen 200, better protecting the display screen 200, and the space occupied by the display screen 200 when in the storage position will be reduced as much as possible. Moreover, the transition between the display screen 200 and the screen mounting surface 110 is also smoother, avoiding the height difference between the transition between the display screen 200 and the screen mounting surface 110, thereby avoiding the accumulation of dust at the transition between the display screen 200 and the screen mounting surface 110, making the appearance of the seat armrest 1 more tidy.

[0119] In addition, 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 constitutes a flip edge 211, and the flip edge 211 is flush with the screen mounting surface 110. In this way, when the display screen 200 flips from the storage position to the extended position, the flip edge 211 can always remain flush with the screen mounting surface 110, that is, in the process of flipping the display screen 200 from the storage position to the extended position, the position of the flip edge 211 of the display screen 200 can remain unchanged, which can prevent the entire screen of the display screen 200 from moving forward or downward, and the display screen 200 has better rotation stability, and the space required for movement is also smaller. After rotating to the extended position, it is more convenient for users to watch, which is conducive to improving the viewing experience. In addition, the gap between the display screen 200 and the armrest body 100 will not change or change very little, thereby avoiding dust accumulation at the transition point, making the appearance of the seat armrest 1 more neat, and avoiding the situation of pinching the hand, and providing a better user experience.

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

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

[0122] The posture adjustment assembly 2 includes a rotating mechanism 800 and a connecting rod mechanism 360. The connecting rod mechanism 360 includes a connecting rod 890 and a bracket 300. One end of the connecting rod 890 is rotatably connected to the rotating mechanism 800. The display screen 200 is installed 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, so that the other end of the connecting rod 890 drives the bracket 300 to flip, thereby driving the display screen 200 to flip between the storage position and the extended position. The bracket 300 includes an arc-shaped plate segment 310. The bracket 300 drives the display screen 200 to flip around the central axis of the arc-shaped plate segment 310.

[0123] The posture adjustment assembly 2 for a display screen according to the embodiment of the present invention can store and raise the display screen 200, and the space required for the movement of the display screen 200 is small, and has the advantages of small space occupation, easy viewing and flat appearance.

[0124] The following describes a seat armrest screen according to an embodiment of the present invention 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 an 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 flip between a storage position and an extended position relative to the armrest body 100.

[0125] According to the seat armrest screen of the embodiment of the present invention, by utilizing the posture adjustment component 2 for the display screen according to the above-mentioned embodiment of the present invention, the display screen 200 can be stored and raised, and the space required for the movement of the display screen 200 is small, and it has the advantages of small space occupation, easy viewing and flat appearance.

[0126] According to some specific embodiments of the present invention, Figure 1 , Figure 3 and Figure 4 As shown, the axial direction of the rotating mechanism 800 is arranged parallel to the flip axis of the display screen 200. In this way, the size of the posture adjustment component 2 in the direction perpendicular to the flip axis of the display screen 200 can be reduced, which is conducive to the miniaturization of the posture adjustment component 2, and is suitable for the armrest body 100 with a smaller size in the direction perpendicular to the flip axis of the display screen 200.

[0127] In some specific embodiments of the present invention, Figure 1 , Figure 3 and Figure 4 As shown, 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 posture adjustment component 2 and driven to flip through the posture adjustment component. The display screen 200 can flip around the flip edge 211 of the display surface 210 during the flipping process, and the position of the flip edge 211 can remain unchanged. It can be understood that the flip edge 211 of the display surface 210 is also a side edge of the upper surface of the display screen 200. This setting can avoid the gap change or height difference between the flip edge 211 and the screen mounting surface 110 during the flipping process of the display screen 200, thereby avoiding the height of the display screen 200 from dropping, so that the flip edge 211 and the screen mounting surface 110 can be kept flush, and the rotation stability of the display screen 200 is higher.

[0129] According to some specific embodiments of the present invention, Figure 4 and Figure 8 As shown, the linkage mechanism 360 includes a link 890 and a bracket 300 .

[0130] One end of the connecting rod 890 is rotatably connected to the rotating mechanism 800, the display screen 200 is installed on the bracket 300, and 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, so that the other end of the connecting rod 890 drives the bracket 300 to flip, thereby driving the display screen 200 to flip between the storage position and the extended position.

[0131] By setting the bracket 300, the connection area between the posture adjustment component 2 and the display screen 300 can be increased, thereby ensuring the connection reliability between the posture adjustment component 2 and the display screen 300. By setting the connecting rod 890, the power transmission and displacement between the bracket 300 and the rotating mechanism 800 can be realized, thereby realizing the bracket 300 driving the display screen 200 to switch between the storage position and the extended position.

[0132] According to some specific embodiments of the present invention, Figure 4 and Figure 8 As shown, 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. In this way, the size of the posture adjustment component 2 in the direction of the flip axis of the vertical display screen 200 can be reduced, which is conducive to the miniaturization of the posture adjustment component 2, and is suitable for the armrest body 100 with a smaller size in the direction of the flip axis of the vertical display screen 200.

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

[0134] That is to say, the display screen 200 of the embodiment of the present invention may not rotate around a physical axis, and the rotation axis of the bracket 300 is set to coincide with the flip edge 211 of the display surface 210, so that the bracket 300 can drive the display screen 200 to rotate around the flip edge 211 of the display surface 210 when rotating, and 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, which can not only improve the dustproof and waterproof performance of the seat armrest 1, but also make the connection between the display screen 200 and the screen mounting surface 110 when in the extended position more regular and more beautiful in appearance.

[0135] In addition, it can be understood that the bracket 300 moves in an arc shape during the rotation process. By setting the arc plate segment 310, the area swept by the arc plate segment 310 during rotation can be smaller, which can not only reduce the volume of the bracket 300 and the space required for the bracket 300 when rotating, but also avoid 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, Figure 4 , Figure 8 and Fig. 9 As shown, the bracket 300 further includes a flat plate section 350, which is connected to one side of the arc length direction of the arc plate section 310, the display screen 200 is mounted on the flat plate section 350, and one end of the connecting rod 890 is rotatably connected to the connection between the flat plate section 350 and the arc plate section 310. In this way, the stability of the bracket 300 during movement is improved, thereby improving the stability of the display screen 200 when moving between the storage position and the extended position, and reducing the probability of the display screen 200 falling.

[0137] According to some specific embodiments of the present invention, Figure 5 As shown, 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 in the armrest body 100, of course, the bracket 300 is also located in the armrest body 100. In this way, not only can the armrest body 100 be used to shield the posture adjustment component 2, making the appearance more beautiful, but also the posture adjustment component 2 can be protected to prevent the user from accidentally colliding with the posture adjustment component 2 and damaging the posture adjustment component 2, and the user's riding experience is also better.

[0139] In some specific embodiments of the present invention, Figure 2and Figure 3 , Figure 4 and Figure 5 As shown, the seat armrest 1 further 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 storage position, the cover plate 400 is located in the storage slot 120 . When the display screen 200 is in the extended position, the cover plate 400 blocks the portion of the bracket 300 extending out of the storage slot 120 .

[0141] Among them, the cover plate 400 can be fixedly installed on the display screen 200, that is, the cover plate 400 can be flipped together with the display screen 200, and the cover plate 400 is connected to the side of the display screen 200 that is opposite to the display surface 210, so that when the display screen 200 is in the storage position, the cover plate 400 can also be located in the storage groove 120, and then the display screen 200 can be used to cover the cover plate 400, and the cover plate 400 will not expose the armrest body 100 to ensure the overall appearance of the seat armrest 1. When the display screen 200 is in the extended position, the cover plate 400 can rotate with the display screen 200 to extend out of the storage groove 120, and the cover plate 400 can cover the part of the bracket 300 exposed in the storage groove 120, and the user will not directly observe the bracket 300, the appearance is more beautiful, and the user can be prevented from touching the bracket 300, and the bracket 300 can be prevented from pinching the hand when rotating, which is safer.

[0142] In addition, the cover plate 400 may also be constructed in an arc shape that is compatible with the arc-shaped plate section 310 of the bracket 300 , so that the space occupied by the cover plate 400 may be smaller, which is convenient for layout.

[0143] In some specific embodiments of the present invention, Figure 5 , Figure 6 and Figure 8 As shown, the posture adjustment assembly 2 further includes a slide rail frame 500 .

[0144] The relative positions of the slide rail frame 500 and the armrest body 100 are fixed, and the slide rail frame 500 is configured with an arc-shaped guide cavity 510, and the arc-shaped plate segment 310 of the bracket 300 can be slidably matched with the arc-shaped guide cavity 510 to limit the bracket 300 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 flip edge 211 of the display surface 210, that is, the arc-shaped guide cavity 510 of the slide rail frame 500 limits the bracket 300 to rotate around the arc-shaped plate segment 310 and around the flip edge 211 of the display surface 210.

[0145] That is to say, the position of the slide frame 500 remains unchanged during the flipping process of the display screen 200, and the arc-shaped guide cavity 510 of the slide frame 500 can guide the rotation of the bracket 300. At the same time, the slide frame 500 can also play the role of fixing and supporting the bracket 300, so that the overall structure of the posture adjustment component 2 is more stable, the rotation of the bracket 300 is smoother, and the rotation stability of the display screen 200 is further improved. The flipping edge 211 of the display surface 210 will not be offset, and the display screen 200 will be better fitted with the screen mounting surface 110 during the flipping process.

[0146] Furthermore, if Figure 5 , Figure 6 and Figure 8 As shown, a damping member 320 is provided between the arc plate segment 310 and the inner wall of the arc guide cavity 510, wherein the damping member 320 may be a damping sleeve, a spring or a damper, etc., and the damping member 320 is used to apply a damping force to the rotation of the bracket 300. By adding the damping member 320, the damping force between the bracket 300 and the arc guide cavity 510 can be increased, so that the rotation of the bracket 300 is more stable, and the bracket 300 is prevented from rotating rapidly, thereby making the rotation of the display screen 200 more gentle, and facilitating the user to adjust the rotation position of the display screen 200. At the same time, the damping member 320 can be used to absorb the instantaneous impact on the display screen 200 or the bracket 300, thereby preventing the bracket 300 from being broken or damaged. In addition, the damping member 320 can also eliminate the gap between the bracket 300 and the slide rail frame 500 and the gap between the teeth in the posture adjustment component 2, thereby preventing the bracket 300 and the slide rail frame 500 from colliding and generating noise and vibration noise.

[0147] Furthermore, if Figure 5 , Figure 6 and Figure 8 As shown, the damping member 320 is disposed on both axial sides of the arc-shaped plate segment 310. In this way, there is a damping force between both axial sides of the arc-shaped plate segment 310 and the arc-shaped guide cavity 510, so that the damping force distribution between the arc-shaped plate segment 310 and the inner wall of the arc-shaped guide cavity 510 is more uniform, and the rotation stability of the bracket 300 is further improved, and the flipping of the display screen 200 is more stable and reliable, and the shaking of the display screen 200 is avoided, and the user has a better viewing experience.

[0148] For example, Figure 5 , Figure 6 and Figure 8As shown, the damping member 320 can be a damping sleeve, and a mounting groove 321 can be provided on the side of the damping member 320 facing the arc plate segment 310, and plug blocks 312 are provided on the axial sides of the arc plate segment 310, and the plug blocks 312 can be inserted into the mounting groove 321 of the damping member 320, thereby realizing the fixation of the damping member 320 and the arc plate segment 310, wherein the thickness of the damping member 320 can be greater than the thickness of the arc plate segment 310, and the thickness of the plug block 312 can be less than the thickness of the remaining part of the arc plate segment 310, and the arc guide cavity 210 has a first arc guide wall 511 and a second arc guide wall 512, and the first arc guide wall 511 and the second arc guide wall 512 are respectively arranged on both sides of the arc plate segment 310 in the thickness direction of the arc plate segment 310, and each damping member 320 is in contact with and cooperates with the first arc guide wall 511 and the second arc guide wall 512 respectively.

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

[0150] Furthermore, the arc-shaped guide cavity 510 can guide the two damping members 320 at the same time, thereby reducing the assembly error between the two damping members 320 and facilitating the reduction of the transmission error between the internal gears of the posture adjustment assembly 2 .

[0151] According to some specific embodiments of the present invention, Figure 5 , Figure 6 and Figure 8 As shown, the posture adjustment assembly 2 further includes a housing 600 and a driving mechanism 700 .

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

[0153] Among them, the driving mechanism 700 can be a motor, and the posture adjustment component 2 can automatically drive the bracket 300 to rotate through the driving mechanism 700, thereby realizing automatic flipping of the display screen 200. Compared with manual flipping of the display screen 200, the operation is more convenient and quick, and the user experience is better.

[0154] Furthermore, all components of the posture adjustment assembly 2 can be installed in the shell 600, such as the driving mechanism 700, the rotating mechanism 800 and the bracket 300. The bracket 300 can be located in the shell 600 when the display screen 200 is in the storage position, and can be extended out of the shell 600 when the display screen 200 is in the extended position.

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

[0156] According to some specific embodiments of the present invention, Figure 5 , Figure 6 and Figure 8 As shown, the driving mechanism 700 is arranged at one end of the axial direction of the rotating mechanism 800. In this way, the size of the posture adjustment component 2 in the direction of the flip axis of the vertical display screen 200 can be reduced, which is conducive to the miniaturization of the posture adjustment component 2, and is suitable for the armrest body 100 with a smaller size in the direction of the flip axis of the vertical display screen 200.

[0157] According to some specific embodiments of the present invention, Figure 4 and Figure 8 As shown, the rotation mechanism 800 includes a connecting rod bushing 810 .

[0158] The connecting rod sleeve 810 is provided with a first shaft hole 811 , one end of the connecting rod 890 is provided with a second shaft hole 891 , and one end of the connecting rod 890 is rotatably connected to the connecting rod sleeve 810 via a connecting rod shaft 892 that fits in 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 driving 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 flipping, extension and storage of the display screen 200.

[0160] According to some specific embodiments of the present invention, Figure 4 and Figure 8 As shown, the outer circumferential surface of the connecting rod sleeve 810 is provided with first axial ears 812 arranged at intervals along the axial direction of the connecting rod sleeve 810, each first axial ear 812 is provided with a first axial hole 811, and one end of the connecting rod 890 is located between adjacent first axial ears 812. By arranging one end of the connecting rod 890 between adjacent first axial ears 812, not only can the transmission connection between the connecting rod sleeve 810 and the connecting rod 890 be achieved, but the first axial ear 812 can also position the connecting rod 890 in the axial direction of the connecting rod sleeve, thereby ensuring the relative position between the connecting rod sleeve 810 and the connecting rod 890.

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

[0162] The connecting rod sleeve 810 is connected to the driving mechanism 700 through the transmission shaft 820. The outer peripheral surface of the transmission shaft 820 is provided with a ring piece 830. The connecting rod sleeve 810 is sleeved on the transmission shaft 820 and rotates synchronously with the transmission shaft 820. The fixing piece 840 is installed on the transmission shaft 820. The connecting rod sleeve 810 is confined between the ring piece 830 and the fixing piece 840 in the axial direction of the transmission shaft 820.

[0163] In other words, the annular piece 830 and the fixing piece 840 are respectively located at the two axial ends of the connecting rod sleeve 810, so that the annular piece 830 and the fixing piece 840 can be used to axially limit the connecting rod sleeve 810, so that the relative positions of the connecting rod sleeve 810 and the transmission shaft 820 in the axial direction of the transmission shaft 820 are fixed, and the connecting rod sleeve 810 will not shake, which is conducive to making the power transmission between the connecting rod sleeve 810 and the bracket 300 more stable.

[0164] Furthermore, if Figure 4 and Figure 8 As shown, the rotating mechanism 800 further includes an elastic member 850 , which is sleeved on the transmission shaft 820 and abutted between the connecting rod sleeve 810 and the fixing member 840 .

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

[0166] In some specific embodiments of the present invention, Figure 4 and Figure 8As shown, the rotating mechanism 800 also includes a gasket 860, which is sleeved on the transmission shaft 820 and located between the elastic member 850 and the connecting rod sleeve 810. In this way, the elastic member 850 can be stopped against the connecting rod sleeve 810 through the gasket 860. By adding the gasket 860, it is convenient to stop against the elastic member 850. The abutment between the elastic member 850 and the gasket 860 is more stable, and the contact area between the gasket 860 and the connecting rod sleeve 810 is larger, so that the elastic member 850 can reliably press the connecting rod sleeve 810 against the annular piece 830, further improving the axial fixing effect of the connecting rod sleeve 810.

[0167] In some specific embodiments of the present invention, Figure 4 and Figure 8 As shown, 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 sleeve 810 and the ring plate 830 and rotates synchronously with the transmission shaft 820. The friction plate 880 is arranged between the transmission block 870 and the connecting rod sleeve 810. The transmission block 870 transmits the rotation of the transmission shaft 820 to the connecting rod sleeve 810 through the friction plate 880.

[0169] It should be noted that the friction force between the friction plate 880 and the transmission block 870, and the friction force between the friction plate 880 and the connecting rod sleeve 810 are both greater than the driving force required for flipping the display screen 200. In this way, when the display screen 200 is actively driven to flip through the driving mechanism 700, the transmission block 870 can transmit power to the connecting rod sleeve 810 through the friction plate 880, and then drive the connecting rod sleeve 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, for example, when the user manually turns the display screen 200 or accidentally collides with the display screen 200, if the external force is greater than the friction between the friction plate 880 and the transmission block 870, or the external force is greater than the friction between the friction plate 880 and the connecting rod sleeve 810, relative rotation will occur between the connecting rod sleeve 810 and the friction plate 880 or between the friction plate 880 and the transmission block 870, and the display screen 200 will be pushed to flip by the external force. This arrangement 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, Figure 4 and Figure 8 As shown, one of the ring piece 830 and the transmission block 870 is provided with a slot 831 and the other is provided with a tooth 871 , and 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 piece 830 can be provided with a slot 831 and the transmission block 870 can be provided with a tooth 871. In this way, when the ring piece 830 rotates synchronously with the transmission shaft 820, the power can be transmitted to the transmission block 870 through the cooperation of the slot 831 and the tooth 871, so that the transmission block 870 can rotate synchronously with the transmission shaft 820, and through the transmission cooperation of the slot 831 and the tooth 871, the power transmission between the ring piece 830 and the transmission block 870 is more stable and reliable.

[0173] Furthermore, if Figure 4 and Figure 8 As shown, there are a plurality of slots 831 arranged at intervals along the circumference of the ring piece 830, and a plurality of teeth 871 arranged at intervals along the circumference of the transmission block 870, and the plurality of teeth 871 are inserted into the plurality of slots 831 in a one-to-one correspondence. In this way, when the ring piece 830 transmits power to the transmission block 870, the circumferential force of the ring piece 830 and the transmission block 870 is more uniform, so that the power transmission between the ring piece 830 and the transmission block 870 is more stable and reliable, and the failure of the power transmission between the ring piece 830 and the transmission block 870 is more effectively avoided. For example, when one of the plurality of teeth 871 and the plurality of slots 831 is damaged and fails, the cooperation of the remaining plurality of teeth 871 and the plurality of slots 831 can still ensure the power transmission between the ring piece 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 sleeve 810 and the ring plate 830 and rotates synchronously with the transmission shaft 820. The clutch device is arranged between the transmission block 870 and the connecting rod sleeve 810. The clutch device controls whether power is transmitted between the transmission block 870 and the connecting rod sleeve 810.

[0176] Specifically, when the clutch device is engaged, the clutch device can transmit power, that is, the transmission block 870 can transmit power to the connecting rod sleeve 810 through the clutch device, and then drive the connecting rod sleeve 810 to rotate, so as to realize the driving mechanism 700 driving the display screen 200 to flip; when the clutch device is disengaged, the power transmission of the clutch device is interrupted, that is, no power is transmitted 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 device, thereby protecting the driving mechanism 700.

[0177] In some specific embodiments of the present invention, Figure 4 and Figure 8As shown, the outer peripheral surface of the transmission shaft 820 is provided with a groove 821, and the fixing member 840 is a retaining spring, which is clamped in the groove 821. Thus, the groove 821 can pre-position the retaining spring, and after the retaining spring is clamped in the groove 821, the axial direction of the connecting rod sleeve 810 can be limited.

[0178] In some specific embodiments of the present invention, Figure 4 and Figure 8 As shown, the driving mechanism 700 is a motor, and the posture adjustment component 2 also includes a speed reduction and torque increase mechanism 900. The transmission shaft 820 is connected to the driving mechanism 700 through the speed reduction and torque increase mechanism 900. The speed reduction and torque increase mechanism 900 includes a primary worm 910, a primary gear 920, a secondary worm 930 and a secondary gear 940.

[0179] The first-stage worm 910 is sleeved on the motor shaft of the motor and driven to rotate by the motor shaft, the first-stage gear 920 is installed on the housing 600 and meshes with the first-stage worm 910, the second-stage worm 930 is installed on the housing 600 and rotates synchronously with the first-stage gear 920, the second-stage gear 940 is sleeved on the transmission shaft 820 and rotates synchronously with the transmission shaft 820, and the second-stage gear 940 meshes with the second-stage worm 930.

[0180] In this way, when the user needs to rotate the display screen 200, the driving mechanism 700 can be started, and the driving mechanism 700 can drive the primary worm gear 910 to rotate, and the power can be transmitted to the rotating mechanism 800 through the primary worm gear 910, the primary gear 920, the secondary worm gear 930 and the secondary gear 940 in sequence, and then the display screen 200 is driven to flip through the rotating mechanism 800, and through the gear teeth cooperation of the speed reduction and torque increase mechanism 900, the rotation speed transmitted from the driving mechanism 700 to the rotating mechanism 800 can be effectively reduced, and then the torque transmitted from the driving mechanism 700 to the rotating mechanism 800 can be increased, so that the flipping of the display screen 200 is smoother.

[0181] Furthermore, the central axis of the primary worm 910 coincides with the central axis of the motor shaft, the central axis of the primary gear 920 coincides with the central axis of the secondary worm 930 and is perpendicular to the central axis of the primary worm 910, and the central axis of the secondary gear 940 coincides with the central axis of the transmission shaft 820 and is perpendicular to the secondary worm 930. In this way, the structural layout of the driving mechanism 700, the primary worm 910, the primary gear 920, the secondary worm 930 and the secondary gear 940 is more compact, so that the driving mechanism 700, the primary worm 910, the primary gear 920, the secondary worm 930 and the secondary gear 940 occupy less space and are easy to arrange.

[0182] In some specific embodiments of the present invention, Figure 4 and Figure 8As shown, one of the outer circumference of the transmission shaft 820 and the inner circumference of the secondary gear 940 is provided with a transmission rib 822 and the other is provided with a transmission groove 941, and 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 circumference of the transmission shaft 820 can be provided with a transmission rib 822 and the inner circumference of the secondary gear 940 can be provided with a transmission groove 941. In this way, when the driving mechanism 700 is running, the secondary gear 940 can transmit power to the transmission shaft 820 through the cooperation of the transmission groove 941 and the transmission rib 822, so that the transmission shaft 820 can rotate synchronously with the secondary gear 940, and through the transmission cooperation of the transmission groove 941 and the transmission rib 822, the power transmission between the secondary gear 940 and the transmission shaft 820 is more stable and reliable.

[0184] Furthermore, if Figure 4 and Figure 8 As shown, a plurality of transmission ribs 822 are arranged at intervals along the circumference of the transmission shaft 820 , a plurality of transmission grooves 941 are arranged at intervals along the circumference of the secondary gear 940 , and the plurality of transmission ribs 822 are inserted into the plurality of transmission grooves 941 in a one-to-one correspondence.

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

[0186] In some specific embodiments of the present invention, Figure 4 and Figure 8 As shown, the transmission rib 822 is arranged on the outer circumferential surface of the transmission shaft 820, and the end of the transmission rib 822 facing away from the connecting rod sleeve 810 has a guide portion 823, and the height of the guide portion 823 gradually decreases in the direction away from the connecting rod sleeve 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 is helpful to simplify the assembly steps of the transmission shaft 820 and the secondary gear 940 and make the assembly more convenient.

[0187] In some specific embodiments of the present invention, Figure 5 and Figure 6 , Figure 9-10As shown, the shell 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 stored position, the bracket 600 stops at the first limiting surface 601. When the display screen 200 is flipped from the stored position to the extended position, the bracket 600 stops at the second limiting surface 602.

[0188] In this way, it can be determined that the flipping range of the display screen 200 is from the storage position to the extended position, thereby preventing the display screen 200 from being flipped too much and being damaged.

[0189] According to some specific embodiments of the present invention, Figure 5 and Figure 6 , Figure 9-10 As shown, the housing 600 has a first limiting rib 650 and a second limiting rib 660, the first limiting rib 650 and the second limiting rib 660 are arranged at intervals, the 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 arranged on the mounting frame 640 described below, and the first limiting rib 650 and the second limiting rib 660 are arranged on one side of the mounting frame 640 close to the display screen 200.

[0190] By providing 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 be deflected. In addition, the first limiting rib 650 and the second limiting rib 660 are arranged at intervals to leave sufficient space for the movement of the connecting rod 890, and the first limiting surface 601 will not interfere with the connecting rod 890.

[0191] According to some specific embodiments of the present invention, Figure 5 and Figure 6 , Figure 9-10 As shown, the bracket 300 is structured with a limit block 340. When the display screen 200 is flipped from the extended position to the storage position, the limit block 340 stops at the first limit surface 601. The limit block 340 is arranged on the side of the flat section 350 that faces away from the display screen 200. By arranging the limit block 340 to cooperate with the first limit surface 601, the reliability of the limit can be improved.

[0192] Furthermore, the bracket 300 further includes a limiting folding plate 330, which is connected to a side of the arc-shaped plate segment 310 in the arc length direction 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 330 stops at the second limiting surface 602. This makes positioning more reliable.

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

[0194] The upper cover 610 and the lower cover 620 are connected to each other and jointly define an installation cavity 630. The installation frame 640 is installed on the lower cover 620 and is located in the installation cavity 630. The driving mechanism 700 and the transmission mechanism 800 are installed on the installation frame 640. The slide rail frame 500 is installed on the installation frame 640. The slide rail frame 500 and the lower cover 620 are arranged on opposite sides of the installation frame 640. The arc plate segment 310 cooperates with the slide rail frame 500 to limit the bracket 300 to rotate around the arc plate segment 310 around its central axis.

[0195] In this way, the upper cover 610 and the lower cover 620 can cover components such as the driving mechanism 700, the rotating mechanism 800, the mounting frame 640 and the slide rail frame 500, so as to make the appearance of the posture adjustment component 2 more beautiful, and can prevent users from directly touching the driving mechanism 700 or the transmission mechanism 800, which is safer. At the same time, the posture adjustment component 2 can also use the mounting frame 640 to fix components such as the driving mechanism 700, the transmission mechanism 800 and the slide rail frame 500, so that the connection and fixation of the various components of the posture adjustment component 2 are more stable. In this way, multiple parts are fixed by one mounting frame 640, which reduces assembly errors, has a better effect on controlling the gear center distance, and can appropriately reduce the noise of the gear transmission.

[0196] The lower cover 620 and the mounting frame 640 are installed with a circuit board 950 , and the circuit board 950 is connected to the driving mechanism 700 for controlling the operation of the driving mechanism 700 .

[0197] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the seat armrest 1 also includes a gesture acquisition device 980 .

[0198] The gesture acquisition device 980 is connected to the posture adjustment component 2 , and the posture adjustment component 2 drives the display screen 200 to flip between the storage position and the extended position according to the gesture information collected by the gesture acquisition device 980 .

[0199] For example, the gesture collection device 980 can be an infrared sensing module, so that the gesture collection device 980 can collect the user's gesture information. The user can rely on different gesture information to control the retraction and extension of the posture adjustment component 2, and then control the display screen 200 to be retracted, extended or flipped to different angles. For example, when the user raises his hand, the display screen 200 can rotate upward following the gesture. When the hand drops, the display screen 200 can rotate downward following the gesture, further simplifying the user's operation. The user does not need to switch the position of the display screen 200 by touching the display screen 200 or pressing a button. The operation is more convenient and quick, which is conducive to improving the user's operating experience.

[0200] In some specific embodiments of the present invention, Figure 5 and Figure 6 As shown, the seat armrest 1 further includes a fingerprint collection device 970. The fingerprint collection device 970 may be a touch screen.

[0201] For example, the fingerprint collection device 970 can be exposed from the armrest body 100 to collect the user's fingerprint information. The fingerprint collection device 970 is connected to 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 according to the fingerprint information collected by the fingerprint collection device 970.

[0202] Specifically, when different users save the information of the flip angle of the display screen 200, the fingerprint can be recorded through the fingerprint collection device 970. When the user uses the display screen 200 next time, by pressing the 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 flip to the corresponding position according to the fingerprint information. In other words, the display screen 200 can have multiple memory positions, and the multiple memory positions correspond to different fingerprint information respectively. When different users use the display screen 200, the display screen 200 can be flipped to the flip angle corresponding to the fingerprint information of the user, further improving the user experience.

[0203] Of course, the same user can also enter multiple fingerprints, and the 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 operation of the posture adjustment component 2 according to the collected fingerprint information to drive the display screen 200 to flip to the position corresponding to the fingerprint of the finger. In this way, the same user can also save multiple flip angles of the display screen 200, which more fully meets the usage needs of different users.

[0204] The following is a brief description of the steps of the posture adjustment component 2 driving the display screen 200 to flip:

[0205] First, the user starts the driving mechanism 700, and the driving mechanism 700 drives the primary worm 910 to rotate, and the primary worm 910 transmits power to the primary gear 920, the secondary worm 930 and the secondary gear 940 in sequence, and the secondary gear 940 rotates;

[0206] Then, the secondary gear 940 transmits the power to the transmission shaft 820 and drives the transmission shaft 820 to rotate synchronously, and the ring piece 830 rotates synchronously with the transmission shaft 820;

[0207] Finally, the ring plate 830 drives the connecting rod sleeve 810 to rotate through the friction plate 880 , and the connecting rod sleeve 810 can drive the bracket 300 to rotate, and the display screen 200 rotates along with the bracket 300 , so that the display screen 200 can be flipped.

[0208] The following is a brief description of the assembly steps of the posture adjustment component 2:

[0209] First, connect the drive mechanism 700 and the mounting frame 640 and fix them with two screws;

[0210] Then, after the secondary gear 940 is sleeved onto the transmission shaft 820, the transmission block 870, the friction plate 880, the connecting rod sleeve 810, the gasket 860, and the elastic member 850 are sleeved into the transmission shaft 820 in sequence, and then the fixing member 840 is snapped into the groove 821 of the transmission shaft 820 to form the rotating mechanism 800, and the installed rotating mechanism 800 and the mounting frame 640 are fixed;

[0211] Next, fix the lower cover 620, the first gear 920 and the second gear 940 to the mounting frame 640 respectively;

[0212] Then, two damping sleeves are respectively mounted on opposite axial sides of the bracket 300, installed in the slide rail bracket 500, and then fixed to the mounting bracket 640 by screws;

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

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