[0110] like Figure 1-Figure 13 As shown, the chair armrest 1 according to the embodiment of the present invention includes an armrest body 100 , a posture adjustment component 2 and a display screen 200 .

[0111] The armrest body 100 has a screen mounting surface 110, and the screen mounting surface 110 is provided with a storage groove 120. The posture adjustment component 2 is provided on the armrest body 100. The posture adjustment component 2 includes a screw mechanism 300 and a connecting rod mechanism 400. The connecting rod mechanism 400 is rotatably connected to the screw mechanism 300. The display screen 200 has a display surface 210. The display screen 200 is mounted on the connecting rod mechanism 400. The screw mechanism 300 drives the connecting rod mechanism 400 to move along its axial direction to drive the display screen 200 to flip between the storage position and the extended position. In particular, 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; when the display screen 200 is in the extended position, at least a portion of the display screen 200 is located outside the storage groove 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.

[0112] 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.

[0113] 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 forms a flip edge 211, 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 forms a flip edge 211, 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.

[0114] 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 the screen mounting surface 110 is provided with a storage groove 120, 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 posture adjustment component 2 includes a screw mechanism 300 and a connecting rod mechanism 400, and the connecting rod mechanism 400 is rotatably connected to the screw mechanism 300, and the display screen 200 has a display surface 210, and the display screen 200 is installed on the connecting rod mechanism 400, and the screw mechanism 300 drives the connecting rod mechanism 400 to move along its axial direction, so as to drive the display screen 200 to flip between the storage position and the extended position.

[0115] 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.

[0116] Furthermore, by driving the display screen 200 to flip through the cooperation of the screw mechanism 300 and the connecting rod mechanism 400, the transmission is more stable, and the space occupied by the screw mechanism 300 and the connecting rod mechanism 400 can be smaller, which is convenient for installing the posture adjustment component 2 in the seat armrest 1, and the overall volume of the seat armrest 1 will not increase or the increase ratio is small, which is convenient for layout.

[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, so that the appearance of the seat armrest 1 is neater.

[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 from entering the transition point, making the appearance of the seat armrest 1 more neat, and avoiding the situation of pinching the hand, and the user experience is better.

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

[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.

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

[0123] The posture adjustment assembly 2 includes a screw mechanism 300 and a connecting rod mechanism 400, the connecting rod mechanism 400 includes a connecting rod 410 and a bracket 420, one end of the connecting rod 410 is rotatably connected to the screw mechanism 300, the display screen 200 is installed on the bracket 420, and the other end of the connecting rod 410 is rotatably connected to the bracket 420. The screw mechanism 300 drives one end of the connecting rod 410 to move, so that the other end of the connecting rod 410 drives the bracket 420 to flip, thereby driving the display screen 200 to flip between the storage position and the extended position.

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

[0125] The following describes 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.

[0126] 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, not only can the display screen 200 be stored and raised, but also 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.

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

[0128] Specifically, the connecting rod mechanism 400 is connected to the lead screw mechanism 300 in a transmission manner, and the connecting rod mechanism 400 can move along the axial direction of the lead screw mechanism 300. When the connecting rod mechanism 400 moves toward one axial end of the lead screw mechanism 300, the connecting rod mechanism 400 can push one end of the display screen 200 to move upward, thereby causing the display screen 200 to flip from the storage position to the extended position. When the connecting rod mechanism 400 moves toward the other axial end of the lead screw mechanism 300, the connecting rod mechanism 400 can drive one end of the display screen 200 to move downward, thereby causing the display screen 200 to flip from the extended position to the storage position. In addition, such a configuration can reduce the space required for the lead screw mechanism 300 and the connecting rod mechanism 400 to move, thereby reducing the space required for the movement of the posture adjustment component 2, making it easier to assemble the posture adjustment component 2 into the armrest body 100, and further reducing the volume of the armrest body 100.

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

[0130] Thus, the display screen 200 can be fixed to the posture adjustment component 2 and driven to flip through the screw mechanism 300 and the connecting rod mechanism 400, and 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 always remain flush, and the rotation stability of the display screen 200 is higher.

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

[0132] One end of the connecting rod 410 is rotatably connected to the screw mechanism 300, the display screen 200 is installed on the bracket 420, and the other end of the connecting rod 410 is rotatably connected to the bracket 420. The screw mechanism 300 drives one end of the connecting rod 410 to move, so that the other end of the connecting rod 410 drives the bracket 420 to flip, thereby driving the display screen 200 to flip between the storage position and the extended position.

[0133] That is to say, the display screen 200 of the embodiment of the present invention may not rotate around a physical axis. Specifically, the display screen 200 may be fixedly connected to the bracket 420, and one end of the connecting rod 410 may be transmission-connected to the screw mechanism 300. When one end of the connecting rod 410 moves along the axial direction of the screw mechanism 300, the other end of the connecting rod 410 may also move radially relative to the screw mechanism 300. That is to say, the other end of the connecting rod 410 may approach or move away from the screw mechanism 300 along the radial direction of the screw mechanism 300, and then the bracket 420 may be driven by the other end of the connecting rod 410 to move in a direction approaching or moving away from the screw mechanism 300, thereby driving the display screen 200 to flip between the storage position and the extended position.

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

[0135] Among them, the rotation axes at both ends of the connecting rod 410 are parallel to the flipping axis of the display screen 200, that is, the rotation axes at both ends of the connecting rod 410 are parallel to the flipping edge 211 of the display surface 210, so that the connecting rod 410 itself will not twist, and the connecting rod 410 can drive the bracket 420 to rotate more stably, thereby improving the stability of the bracket 420 driving the display screen 200 to rotate, and the display screen 200 rotates more smoothly.

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

[0137] By setting the rotation axis of the arc-shaped plate segment 421 to coincide with the flip edge 211 of the display surface 210, the bracket 420 can rotate around the flip edge 211, thereby driving the display screen 200 to rotate around the flip edge 211 of the display surface 210, and the position of the flip edge 211 will not change, thereby avoiding or minimizing the change 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 more regular when in the extended position, and the appearance is more beautiful.

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

[0139] Furthermore, if Figure 6-Figure 10 As shown, the bracket 420 also includes a flat section 422, which is connected to one side of the arc length direction of the arc-shaped plate section 421, and the display screen 200 is installed on the flat section 422. It can be understood that the display screen 200 is usually also planar. By setting the bracket 420 to connect the flat section 422 and the display screen 200, the contact area between the flat section 422 and the display screen 200 is larger, which is easier to connect, and the connection between the flat section 422 and the display screen 200 can be more stable.

[0140] In addition, the other end of the connecting rod 410 is rotatably connected to the connection between the flat plate segment 422 and the arc-shaped plate segment 421. This not only facilitates the connection between the connecting rod 410 and the bracket 420, but also allows the connecting rod 410 to be connected to a position close to the center of the bracket 420, making the supporting force more uniform, thereby further improving the stability of the posture adjustment component 2 in driving the display screen 200 to flip.

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

[0142] Specifically, the bracket 420 is connected to the side of the display screen 200 facing away from the display surface 210. When the display screen 200 is in the storage position, the display screen 200 will cover the posture adjustment component 2, that is, the posture adjustment component 2 will be located in the armrest body 100, of course, the bracket 420 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 armrest body 100 can be used to protect the posture adjustment component 2, thereby preventing 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.

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

[0144] The cover plate 500 is installed on the display screen 200 . When the display screen 200 is in the storage position, the cover plate 500 is located in the storage slot 120 . When the display screen 200 is in the extended position, the cover plate 500 blocks the portion of the bracket 420 extending out of the storage slot 120 .

[0145] Among them, the cover plate 500 can be fixedly connected to the side of the display screen 200 that is opposite to the display surface 210, and the cover plate 500 can be flipped together with the display screen 200, so that when the display screen 200 is in the storage position, the cover plate 500 can also be located in the storage groove 120, and then the display screen 200 can be used to cover the cover plate 500, and the cover plate 500 will not expose the armrest body 100 to ensure the overall neatness of the appearance of the seat armrest 1, and when the display screen 200 is in the extended position, the cover plate 500 can rotate with the display screen 200 to extend out of the storage groove 120, and the cover plate 500 can cover the part of the bracket 420 exposed in the storage groove 120, the user will not directly observe the bracket 420, the appearance is more beautiful, and the user can be prevented from touching the bracket 420, and the bracket 420 can be prevented from pinching the hand when rotating, which is safer.

[0146] In addition, the cover plate 500 may also be configured in an arc shape, so that the space occupied by the cover plate 500 may be smaller, which is convenient for layout.

[0147] In some specific embodiments of the present invention, Figure 5-Figure 7 As shown, the posture adjustment assembly 2 further includes a slide rail frame 600 .

[0148] The relative positions of the slide rail frame 600 and the armrest body 100 are fixed, and the slide rail frame 600 is configured with an arc-shaped guide cavity 610, and the arc-shaped plate segment 421 can be slidably matched with the arc-shaped guide cavity 610 to limit the bracket 420 to rotate around the arc-shaped plate segment 421 around its central axis. The central axis of the arc-shaped guide cavity 610 coincides with the flip edge 211 of the display surface 210, and the arc-shaped guide cavity 610 limits the bracket 420 to rotate around the flip edge 211 of the display surface 210.

[0149] That is to say, the position of the slide frame 600 remains unchanged during the flipping process of the display screen 200, and the arc-shaped guide cavity 610 of the slide frame 600 can guide the rotation of the bracket 420 to make the rotation of the bracket 420 more stable. At the same time, the slide frame 600 can also play a role in fixing and supporting the bracket 420, so that the overall structure of the posture adjustment component 2 is more stable, and the rotation of the bracket 420 is smoother, which further improves the stability of the rotation of the display screen 200. The flipping edge 211 of the display surface 210 will not be offset, and the display screen 200 will better fit the screen mounting surface 110 during the flipping process.

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

[0151] Among them, the damping member 430 can be a damping sleeve, a spring or a damper, etc. By adding the damping member 430, the damping force between the bracket 420 and the inner wall of the arc-shaped guide cavity 610 can be increased, so that the rotation of the bracket 420 is smoother, and the bracket 420 is prevented from rotating rapidly, thereby making the rotation of the display screen 200 smoother, and it is convenient for users to adjust the rotation position of the display screen 200. At the same time, the damping member 430 can be used to absorb the instantaneous impact on the display screen 200 or the bracket 420, thereby avoiding the bracket 420 from breaking and damaging. In addition, the damping member 430 can also eliminate the gap between the bracket 420 and the slide rail frame 600 and the gap between the teeth in the posture adjustment component 2, thereby avoiding the noise and vibration noise generated by the collision between the bracket 420 and the slide rail frame 600.

[0152] In some specific embodiments of the present invention, Figure 5 and Fig.12 As shown, the damping members 430 are disposed on two axial sides of the arc-shaped plate segment 421 .

[0153] In this way, there is damping force between the axial sides of the arc plate segment 421 and the arc guide cavity 610, so that the damping force distribution between the arc plate segment 421 and the inner wall of the arc guide cavity 610 is more uniform, further improving the rotation stability of the bracket 420, and the flipping of the display screen 200 is more stable and reliable, avoiding the shaking of the display screen 200, and the user has a better viewing experience.

[0154] For example, the damping member 430 can be a damping sleeve, and a mounting groove 431 can be provided on the side of the damping member 430 facing the arc plate segment 421, and plug blocks 426 are provided on the axial sides of the arc plate segment 421, and the plug blocks 426 can be inserted into the mounting groove 431 of the damping member 430, thereby realizing the fixation of the damping member 430 and the arc plate segment 421, wherein the thickness of the damping member 430 can be greater than the thickness of the arc plate segment 421, and the thickness of the plug block 426 can be less than the thickness of the rest of the arc plate segment 421, and the arc guide cavity 610 has a first arc guide wall 611 and a second arc guide wall 612, and the first arc guide wall 611 and the second arc guide wall 612 are respectively arranged on both sides of the arc plate segment 421 in the thickness direction of the arc plate segment 421, and each damping member 430 is in contact with and cooperates with the first arc guide wall 611 and the second arc guide wall 612 respectively.

[0155] This facilitates the assembly of the arc-shaped plate segment 421 and the damping member 430. Moreover, after the damping member 430 contacts the first arc-shaped guide wall 611 and the second arc-shaped guide wall 612, the arc-shaped plate segment 421 will not contact the first arc-shaped guide wall 611 and the second arc-shaped guide wall 612, thereby avoiding wear between the arc-shaped plate segment 421 and the first arc-shaped guide wall 611 and the second arc-shaped guide wall 612, and reducing the friction between the bracket 420 and the slide rail frame 600, so as to facilitate the rotation of the bracket 420. In addition, the arc-shaped guide cavity 610 can guide the two damping members 430 at the same time, reducing the assembly error between the two damping members 430, which is conducive to reducing the transmission error between the gears in the posture adjustment assembly 2.

[0156] In some specific embodiments of the present invention, Figure 5 As shown, the posture adjustment assembly 2 further includes a housing 700 and a driving mechanism 800 .

[0157] The shell 700 is installed on the armrest body 100, the driving mechanism 800 is installed on the shell 700, the screw mechanism 300 is transmission-connected to the driving mechanism 800, and the driving mechanism 800 drives the bracket 420 to rotate around the central axis of the arc-shaped plate segment 421 through the screw mechanism 300 and the connecting rod 410, so that the display screen 200 is flipped between the storage position and the extended position.

[0158] Among them, the driving mechanism 800 can be a motor, and the posture adjustment component 2 can automatically drive the bracket 420 to rotate through the driving mechanism 800, 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.

[0159] Furthermore, the components of the posture adjustment assembly 2 can all be installed in the shell 700, such as the drive mechanism 800, the screw mechanism 300 and the connecting rod mechanism 400, wherein the bracket 420 can be located in the shell 700 when the display screen 200 is in the storage position, and can extend out of the shell 700 when the display screen 200 is in the extended position.

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

[0161] In some specific embodiments of the present invention, Figure 5 As shown, the drive mechanism 800 is arranged on one side of the radial direction of the screw mechanism 300. Thus, the drive mechanism 800 and the screw mechanism 300 can be arranged along the radial direction of the screw mechanism 300, and the drive mechanism 800 and the screw mechanism 300 can overlap in the axial direction of the screw mechanism 300. It can be understood that the axial length of the screw mechanism 300 will be greater than its radial length. Such an arrangement can avoid the axial overall length of the drive mechanism 800 and the screw mechanism 300 being too large, which is conducive to reducing the occupied space of the posture adjustment component 2, and the volume of the posture adjustment component 2 can be smaller, which is convenient for arrangement and installation.

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

[0163] The screw rod 310 is in transmission connection with the driving mechanism 800, the first nut 320 is sleeved on the screw rod 310 and threadedly matched with the screw rod 310, and one end of the connecting rod 410 is rotatably connected with the first nut 320. In this way, when the driving mechanism 800 drives the screw rod 310 to rotate, the rotation of the screw rod 310 can be converted into a linear movement of the first nut 320 through the threaded match between the first nut 320 and the screw rod 310, and then the first nut 320 can be driven by the driving mechanism 800 to rotate forward and reversely to move back and forth along the axial direction of the screw rod 310, and the end of the connecting rod 410 connected to the display screen 200 can be rotated relative to the end of the connecting rod 410 connected to the nut, and then the display screen 200 can be driven to flip between the storage position and the extended position.

[0164] Furthermore, if Fig.13As shown, one of the first nut 320 and one end of the connecting rod 410 is provided with a first connecting rod shaft 321 , and the other is provided with a first shaft hole 413 , and the first connecting rod shaft 321 is rotatably matched with the first shaft hole 413 .

[0165] For example, the first nut 320 may be provided with a first connecting rod shaft 321 and the connecting rod 410 may be provided with a first shaft hole 413, so that the first connecting rod shaft 321 may extend into the first shaft hole 413, so that the connecting rod 410 may rotate relative to the first nut 320. When the driving mechanism 800 drives the screw rod 310 to rotate, the first nut 320 moves along the axial direction of the screw rod 310, and the connecting rod 410 may rotate relative to the first nut 320 while following the first nut 320 to move along the axial direction of the screw rod 310, and then the end of the connecting rod 410 away from the first nut 320 may be used to push the bracket 420 to rotate, so as to realize the flipping of the display screen 200. Moreover, with such a configuration, the connection structure between the first nut 320 and the connecting rod 410 is simpler, which can realize the connection and fixation between the first nut 320 and the connecting rod 410 to prevent the first nut 320 and the connecting rod 410 from being separated, and also enable the connecting rod 410 to rotate relative to the first nut 320.

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

[0167] The first connecting plate 411 and the second connecting plate 412 are respectively arranged on two opposite radial sides of the first nut 320 . The first connecting plate 411 and the second connecting plate 412 are respectively provided with first axial holes 413 . The first nut 320 is respectively provided with first connecting rod shafts 321 inserted into the corresponding first axial holes 413 on two opposite radial sides.

[0168] In this way, the first connecting plate 411 and the second connecting plate 412 can respectively stop at the radially opposite sides of the first nut 320. The first connecting plate 411 stops at one radial side of the first nut 320, thereby preventing the connecting rod 410 from shifting toward the direction close to the second connecting plate 412, and the second connecting plate 412 stops at the other radial side of the first nut 320, thereby preventing the connecting rod 410 from shifting toward the direction close to the first connecting plate 411, thereby making the fit between the first connecting rod shaft 321 and the first shaft hole 413 more stable, preventing the connecting rod 410 from detaching from the first nut 320, and making the connection between the connecting rod 410 and the first nut 320 more stable.

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

[0170] In some specific embodiments of the present invention, Fig.13 As shown, a bearing 330 is provided between the outer circumference of the first connecting rod shaft 321 and the inner circumference of the first shaft hole 413. The bearing 330 may be a ball bearing. By adding the bearing 330, the friction between the first connecting rod shaft 321 and the first shaft hole 413 can be reduced, and the resistance of the connecting rod 410 relative to the first nut 320 when rotating is smaller, which can not only reduce the wear of the connecting rod 410 and the wear of the first nut 320, but also make the rotation of the connecting rod 410 easier, further improve the stability of the rotation of the connecting rod 410, and the posture adjustment component 2 can drive the display screen 200 to flip more smoothly.

[0171] In some specific embodiments of the present invention, Figure 5-Figure 7 , Fig.13 As shown, the screw mechanism 300 further includes a second nut 340 and an elastic member 350 .

[0172] The second nut 340 is sleeved on the screw rod 310 and threadably matched with the screw rod 310 . The elastic member 350 is sleeved on the screw rod 310 and abuts between the first nut 320 and the second nut 340 .

[0173] It is understandable that during the production process, in order to ensure that the first nut 320 can be sleeved onto the screw rod 310 and avoid excessive friction resistance between the first nut 320 and the screw rod 310, there usually needs to be a little gap between the threads of the first nut 320 and the screw rod 310. By adding the second nut 340, and after the first nut 320 and the second nut 340 are stopped by the elastic member 350, the elastic force of the elastic member 350 can make the internal threads of the first nut 320 and the second nut 340 always press against the threads on the screw rod 310, thereby achieving the purpose of eliminating the transmission gap between the screw rod 310 and the first nut 320, thereby avoiding the first nut 320 from shaking in the radial and axial directions relative to the screw rod 310, more effectively avoiding the shaking of the display screen 200, and the fixing and flipping of the display screen 200 are more stable.

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

[0175] The nut body 341 is sleeved on the screw rod 310 and threadedly matched with the screw rod 310 , the elastic member 350 stops between the first nut 320 and the nut body 341 , and the accommodating ring 342 is connected to the side of the nut body 341 facing the first nut 320 and surrounds the elastic member 350 and the first nut 320 .

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

[0177] In addition, a notch 343 extending axially along the accommodating ring 342 is provided on the peripheral wall of the accommodating ring 342 , and the first connecting rod shaft 321 is movably engaged with the notch 343 , so that the second nut 340 can use the notch 343 to avoid positional interference between the accommodating ring 342 and the first connecting rod shaft 321 .

[0178] Moreover, after the first connecting rod shaft 321 extends into the notch 343, the opposite sides of the notch 343 along the circumference of the accommodating ring 342 can respectively stop at the opposite sides of the radial direction of the first connecting rod shaft 321. When the driving mechanism 800 drives the screw rod 310 to rotate and move the first nut 320 toward the direction close to the second nut 340, the first nut 320 can push the second nut 340 to move together through the elastic member 350, thereby realizing the flipping of the display screen 200 from the storage position to the extended position (or the flipping of the display screen 200 from the extended position to the storage position). When 310 rotates to move the first nut 320 away from the second nut 340, since the radially opposite sides of the first connecting rod shaft 321 respectively stop on the side walls of the notch 343, the first connecting rod shaft 321 and the second nut 340 cannot rotate relative to each other, that is, the first nut 320 and the second nut 340 will not rotate relative to each other, so that the second nut 340 follows the first nut 320 to rotate relative to the screw rod 310, thereby realizing the flipping of the display screen 200 from the extended position to the storage position (or the flipping of the display screen 200 from the storage position to the extended position).

[0179] In some specific embodiments of the present invention, Figure 5 As shown, the driving mechanism 800 is a motor, and the posture adjustment component 2 also includes a deceleration and torque-increasing mechanism 900. The screw rod 310 is transmission-connected to the driving mechanism 800 via the deceleration and torque-increasing mechanism 900. The deceleration and torque-increasing mechanism 900 includes a primary worm 910, a primary gear 920, a secondary worm 930 and a secondary gear 940.

[0180] 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 700 and meshes with the first-stage worm 910, the second-stage worm 930 is installed on the housing 700 and rotates synchronously with the first-stage gear 920, the second-stage gear 940 is sleeved on the lead screw 310 and rotates synchronously with the gear shaft, and the second-stage gear 940 meshes with the second-stage worm 930.

[0181] In this way, when the user needs to rotate the display screen 200, the driving mechanism 800 can be started, and the driving mechanism 800 can drive the first-stage worm gear 910 to rotate, and the power can be transmitted to the screw mechanism 300 through the first-stage worm gear 910, the first-stage gear 920, the second-stage worm gear 930 and the second-stage gear 940 in sequence, and then the display screen 200 is driven to flip through the screw mechanism 300 and the connecting rod mechanism 400. In addition, through the gear tooth cooperation of the speed reduction and torque increase mechanism 900, the rotation speed transmitted from the driving mechanism 800 to the screw mechanism 300 can be effectively reduced, and then the torque transmitted from the driving mechanism 800 to the screw mechanism 300 can be increased, so that the flipping of the display screen 200 is smoother.

[0182] Furthermore, if Figure 5-Figure 7 As shown, 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 lead screw 310 and is perpendicular to the secondary worm 930. In this way, the structural layout of the driving mechanism 800, 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 800, 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.

[0183] In some specific embodiments of the present invention, Fig.13 As shown, the screw rod 310 includes a threaded section 311 and a connecting section 312 connected to each other, the cross-sectional area of ​​the connecting section 312 is larger than the cross-sectional area of ​​the threaded section 311, and the first nut 320 is sleeved on the threaded section 311 and threadedly engaged with the threaded section 311. In this way, the end of the connecting section 312 facing the threaded section 311 can stop and limit the first nut 320, preventing the first nut 320 from moving to the connecting section 312 or even detaching from the screw rod 310, so that the first nut 320 and the screw rod 310 can cooperate more stably and reliably.

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

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

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

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

[0188] In some specific embodiments of the present invention, Fig.13 As shown, the transmission rib 313 is arranged on the outer peripheral surface of the connecting section 312, and the end of the transmission rib 313 facing away from the threaded section 311 has a guide portion, and the height of the guide portion gradually decreases in the direction away from the threaded section 311, so that when assembling the connecting section 312 and the secondary gear 940, the guide portion can guide the assembly of the transmission rib 313 and the transmission groove 941, which is helpful to simplify the assembly steps of the connecting section 312 and the secondary gear 940 and make the assembly more convenient.

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

[0190] When the display screen 200 is flipped from the extended position to the storage position, the bracket 420 stops at the first limit surface 710, and when the display screen 200 is flipped from the storage position to the extended position, the bracket 420 stops at the second limit surface 720. 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, so as to avoid the display screen 200 being flipped too much and damaged.

[0191] In some specific embodiments of the present invention, Fig.11 As shown, the shell 700 has a first limiting rib 730 and a second limiting rib 740, the first limiting rib 730 and the second limiting rib 740 are arranged at intervals, the connecting rod 410 is located between the first limiting rib 730 and the second limiting rib 740, the first limiting rib 730 forms a first limiting surface 710 and a second limiting surface 720, and the second limiting rib 740 forms a first limiting surface 710 and a second limiting surface 720.

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

[0193] Furthermore, by setting two limiting ribs to limit the bracket 420, it is possible to prevent the bracket 420 from deflecting or shaking after it stops at a single limiting rib, which is beneficial to improving the limiting effect of the bracket 420 and allowing the display screen 200 to remain stable in the stored position and the extended position.

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

[0195] In addition, when the display screen 200 is flipped from the extended position to the storage position, the axial ear 423 stops at the first limiting surface 710. In this way, the axial ear 423 can be used to connect the bracket 420 and the connecting rod 410 to achieve relative rotation of the bracket 420 and the connecting rod 410, and the axial ear 423 can be used to limit the bracket 420 to achieve the limitation of the display screen 200 in the storage position. Therefore, there is no need to set up an additional structure for limiting the first limiting surface 710, which is conducive to simplifying the structure of the bracket 420.

[0196] Furthermore, if Fig.12As shown, the bracket 420 also includes a limiting folding plate 425, which is connected to the side of the arc-shaped plate segment 421 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 425 stops at the first limiting surface 710, thereby limiting the display screen 200 in the extended position, and the positioning is more accurate and reliable to avoid excessive rotation of the display screen 200.

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

[0198] The upper cover 750 and the lower cover 760 are connected to each other and jointly define an installation cavity 770. The mounting frame 780 and the circuit board are installed on the lower cover 760 and are located in the installation cavity 770. The driving mechanism 800 and the screw mechanism 300 are installed on the mounting frame 780. The slide rail frame 600 is installed on the mounting frame 780. The slide rail frame 600 and the lower cover 760 are arranged on opposite sides of the mounting frame 780. The arc plate segment 421 cooperates with the slide rail to limit the rotation of the bracket 420 around the central axis of the arc plate segment 421.

[0199] In this way, the upper cover 750 and the lower cover 760 can cover components such as the drive mechanism 800, the screw mechanism 300, the connecting rod mechanism 400, the mounting frame 780 and the slide rail frame 600, so as to make the appearance of the posture adjustment component 2 more beautiful, and can prevent users from directly touching the drive mechanism 800 or the screw mechanism 300 and the connecting rod mechanism 400, which is safer. At the same time, the posture adjustment component 2 can also use the mounting frame 780 to fix components such as the drive mechanism 800, the screw mechanism 300 and the slide rail frame 600, so as to make the connection and fixation of the components of the posture adjustment component 2 more stable. In this way, multiple parts are fixed by one mounting frame 780, which reduces assembly errors, has a better effect on controlling the center distance of the gears, and can appropriately reduce the noise of the gear transmission.

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

[0201] The gesture acquisition device 950 is connected to the posture adjustment component 2 , and the posture adjustment component 2 drives the display screen 200 to switch between the storage position and the extended position according to the gesture information collected by the gesture acquisition device 950 .

[0202] For example, the gesture collection device 950 can be an infrared sensing module, so that the gesture collection device 950 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.

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

[0204] The fingerprint collection device is connected to the posture adjustment component 2, and the posture adjustment component 2 drives the display screen 200 to switch between the storage position and the extended position according to the fingerprint information collected by the fingerprint collection device.

[0205] 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. When the user uses the display screen 200 next time, by pressing the finger to the fingerprint collection device, the fingerprint collection device can control the posture adjustment component 2 to drive the display screen 200 to flip to the corresponding position according to the fingerprint information. That is to say, 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.

[0206] 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 with different fingers, the fingerprint collection device 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.

[0207] The following is a brief description of the steps of the posture adjustment component 2 driving the display screen 200 to flip:

[0208] First, the user starts the driving mechanism 800, and the driving mechanism 800 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;

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

[0210] Finally, the connecting rod 410 follows the first nut 320 to move along the axial direction of the screw rod 310 and rotate relative to the first nut 320. The connecting rod 410 pushes the bracket 420 to rotate while moving, and the display screen 200 follows the bracket 420 to rotate, so that the display screen 200 can be flipped.

[0211] The following is a brief description of the assembly steps of the posture adjustment component 2:

[0212] First, connect the primary worm 910 to the drive mechanism 800, and then connect the drive mechanism 800 to the mounting bracket 780, and then fix them with two screws;

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

[0214] Next, the connecting rod 410 is fixed to the first nut 320 through two bearings 330, and then connected to the mounting frame 780, and the lower cover 760, the first gear 920 and the second worm 930 are fixed to the mounting frame 780 in sequence;

[0215] Then, two damping sleeves are respectively mounted on opposite axial sides of the bracket 420, installed in the slide rail bracket 600, and then fixed to the mounting bracket 780 by screws;

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