For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0043] Reference is made below Figures 1-4 The driving assembly 10 according to the embodiments of the utility model is described.

[0044] As Figures 1-4 shown, the driving assembly 10 according to the embodiments of the utility model comprises: a base plate 1, a sliding plate 2 and a driving mechanism 3.

[0045] Specifically, referring to Figures 1-4 , the driving assembly 10 is used to drive the folding of the display screen 20, the base plate 1 is two, and one end of the two base plates 1 in the width direction is rotatably connected, wherein the two base plates 1 are connected with the display screen 20, one end of the two base plates 1 in the width direction is rotatably connected, so that the display screen 20 can be driven to fold (for example, connected with the display screen 20 through a connecting structure), the display screen 20 is arranged on one side of the two base plates 1 in the thickness direction, and is spaced apart from the two base plates 1, so that when the two base plates 1 rotate relatively, the folding of the display screen 20 is avoided.

[0046] Further, as Figures 1-4 shown, the sliding plate 2 is two, and the two sliding plates 2 are arranged on the same side of the two base plates 1 in the thickness direction, and the two sliding plates 2 are movable along the width direction of the two base plates 1 respectively.

[0047] Two sliding plates 2 are respectively disposed on the side of the two substrates 1 facing the display screen 20 in the thickness direction. Both sliding plates 2 abut against the display screen 20, thereby allowing the sliding plates 2 to support the display screen 20. The two sliding plates 2 are movable along the width direction of the two substrates 1, for example... Figure 3 As shown, when the two sliding plates 2 move towards each other, the display screen 20 changes from a folded state to a flat state. Simultaneously, one side of the two sliding plates 2 abuts against each other in the width direction, thereby reducing the gap between the two sliding plates 2 and preventing the display screen 20 from collapsing in the gap, thus ensuring the display effect of the display screen 20. For example... Figure 4 As shown, when the two slide plates 2 move away from each other, the display screen 20 changes from a flat state to a folded state. At this time, the gap between the two slide plates 2 increases, thereby providing space for the folding of the display screen 20 and thus avoiding interference with the folding of the display screen 20.

[0048] Furthermore, such as Figures 1-4 As shown, the driving mechanism 3 includes a driving shaft 31 that extends along the length of the substrate 1. The driving shaft 31 is used to simultaneously drive the two sliding plates 2 to move and drive the two substrates 1 to rotate relative to each other. It can be understood that by using a single driving shaft 31 to simultaneously drive the two sliding plates 2 to move and drive the two substrates 1 to rotate relative to each other, the structure can be simplified and the cost reduced while achieving the folding of the display screen 20 by the driving component 10.

[0049] According to the embodiment of the present invention, the driving component 10 is rotatably connected at one end of the width direction of two substrates 1, and two sliding plates 2 are respectively disposed on the same side of the thickness direction of the two substrates 1. The two sliding plates 2 are movable along the width direction of the two substrates 1, and the driving shaft 31 extends along the length direction of the substrate 1. One driving shaft 31 is used to simultaneously drive the two sliding plates 2 to move and drive the two substrates 1 to rotate relative to each other. This allows the structure to be simplified and the cost to be reduced while realizing the folding of the display screen 20 by the driving component 10.

[0050] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a first pin 11 is connected to the substrate 1, and a first sliding hole 21 is provided on the corresponding slide plate 2. The first sliding hole 21 extends along the width direction of the substrate 1, and the first pin 11 is movably disposed in the first sliding hole 21 along the length direction of the first sliding hole 21.

[0051] It can be understood that the arrangement of the first sliding hole 21 and the first pin 11 can limit the movement of the sliding plate 2 in the length direction of the base plate 1, and on the other hand, by the length direction movement of the first pin 11 relative to the first sliding hole 21, the sliding plate 2 can be moved in the width direction of the base plate 1, thereby avoiding the folding of the display screen 20 and achieving better support for the display screen 20.

[0052] In some embodiments of the utility model, as shown in Figure 1 and Figure 2 , the first pin 11 is spaced apart on the same base plate 1, and the first sliding hole 21 on the corresponding sliding plate 2 is one-to-one corresponding to the plurality of first pins 11. Therefore, the relative rotation of the sliding plate 2 and the base plate 1 can be avoided, and the installation of the driving assembly 10 is more stable and reliable. At the same time, the base plate 1 can also better limit the sliding plate 2, avoid the movement of the sliding plate 2 in the length direction of the base plate 1, and make the sliding of the sliding plate 2 more stable and smooth.

[0053] For example, in the examples shown in Figure 1 and Figure 2 , the first pin 11 is spaced apart along the length direction of the sliding plate 2 on the same base plate 1, and the first sliding hole 21 is also one-to-one corresponding to the two, but the utility model is not limited thereto, the first pin 11 can also be spaced apart in any direction, for example, spaced apart along the width direction of the sliding plate 2, and the first pin 11 and the first sliding hole 21 can also be more, for example, 3, 4, 5 or 6, etc.

[0054] In some embodiments of the utility model, as shown in Figure 1 and Figure 2 , the driving mechanism 3 further comprises: two transmission assemblies 32, the two transmission assemblies 32 are respectively arranged between the two base plates 1 and the two sliding plates 2, and are respectively connected with the two base plates 1, the two transmission assemblies 32 are all in transmission connection with the driving shaft 31, and are respectively used for driving the two sliding plates 2 to move along the width direction of the base plate 1.

[0055] It can be understood that the driving shaft 31 can drive the two transmission assemblies 32 to move respectively, and the two transmission assemblies 32 are respectively used for driving the two sliding plates 2 to move along the width direction of the base plate 1, so that one driving shaft 31 can drive the two sliding plates 2 to move along the width direction of the base plate 1 simultaneously.

[0056] In some embodiments of the utility model, as shown in Figure 1 and Figure 2As shown, the transmission assembly 32 comprises a rotating member 321 rotatably arranged on the base plate 1, the axis of the rotating member 321 extends along the thickness direction of the base plate 1, one end of the length direction of the rotating member 321 is in transmission connection with the driving shaft 31, and the rotating member 321 is provided with a second sliding hole 3211 extending along the length direction of the rotating member 321, and the side of the sliding plate 2 facing the base plate 1 is connected with a second pin 22, and the second pin 22 is movably arranged in the second sliding hole 3211 along the length direction of the rotating member 321.

[0057] It should be noted that the transmission assembly 32 further comprises a fixed member 322 fixedly arranged on the base plate 1, and the rotating member 321 is rotatably arranged on the fixed member 322, so that the rotating member 321 is rotatably arranged on the base plate 1.

[0058] It can be understood that, as shown in Figure 1 and Figure 2 , the base plate 1 is connected with a first pin 11, and the corresponding sliding plate 2 has a first sliding hole 21 extending along the width direction of the base plate 1, and the first pin 11 is movably arranged in the first sliding hole 21 along the length direction of the first sliding hole 21, so as to limit the movement of the sliding plate 2 along the width direction of the base plate 1. One end of the length direction of the rotating member 321 is in transmission connection with the driving shaft 31, that is, the driving shaft 31 rotates, so as to drive the rotating member 321 to rotate, and with the rotation of the rotating member 321, the second pin 22 is driven to move in the second sliding hole 3211. Since the sliding plate 2 moves along the width direction of the base plate 1, that is, the freedom degree of the sliding plate 2 along the length direction of the base plate 1 is locked, so as to realize that the driving shaft 31 drives the sliding plate 2 to move along the width direction of the base plate 1.

[0059] Therefore, through the above arrangement, the transmission assembly 32, the sliding plate 2 and the base plate 1 form a crank slider structure, so as to realize that one driving shaft 31 drives two sliding plates 2 to move along the width direction of the base plate 1 at the same time.

[0060] In some embodiments of the utility model, as shown in Figure 1 and Figure 2 , the driving shaft 31 is provided with a worm gear, and the rotating member 321 is provided with a worm, or the driving shaft 31 is provided with a worm, and the rotating member 321 is provided with a worm gear. Therefore, the transmission between the driving shaft 31 and the rotating member 321 is realized. For example, as shown in Figures 1-4 and Figure 1 , the driving shaft 31 is provided with a worm gear, and the rotating member 321 is provided with a worm, wherein the extension direction of the worm on the rotating member 321 is parallel to the thickness direction of the base plate 1.

[0061] In some embodiments of the utility model, as shown in Figure 2As shown, the two substrates 1 are a first substrate 12 and a second substrate 13, respectively. A drive shaft 31 is disposed between the first substrate 12 and the second substrate 13. The first substrate 12 and the second substrate 13 are rotatably connected by the drive shaft 31 (that is, the first substrate 12 and the second substrate 13 rotate around the drive shaft 31, and the rotation axis of the first substrate 12 and the second substrate 13 coincides with the axis of the drive shaft 31). The first substrate 12 is fixedly connected to the drive shaft 31, and the second substrate 13 is sleeved on the drive shaft 31 and rotatably connected to the drive shaft 31.

[0062] It is understandable that, since the first substrate 12 is fixedly connected to the drive shaft 31, the drive shaft 31 can drive the first substrate 12 to rotate around the drive shaft 31 when it rotates. Since the second substrate 13 is sleeved on the drive shaft 31 and is rotatably connected to the drive shaft 31, the second substrate 13 will not rotate with the drive shaft 31 when it rotates, thus realizing the rotation between the first substrate 12 and the second substrate 13.

[0063] In some embodiments of this utility model, such as Figures 1-4 and Figures 1-4 As shown, a first gear 311 is sleeved on the drive shaft 31. The drive mechanism 3 also includes a drive motor 33 and a second gear 34. The drive motor 33 is fixed on the second base plate 13. The second gear 34 is connected to the output shaft of the drive motor 33 and meshes with the first gear 311.

[0064] It is understandable that the output shaft of the drive motor 33 drives the second gear 34 to rotate, the second gear 34 drives the first gear 311 to rotate, and the first gear 311 drives the drive shaft 31 to rotate. Thus, the rotation of the drive shaft 31 is achieved.

[0065] The following is for reference. Figures 1-4 Description of a display assembly 100 according to an embodiment of the present utility model.

[0066] like Figure 3 As shown, the display assembly 100 according to an embodiment of the present invention includes: a display 20 and the aforementioned driving assembly 10.

[0067] Specifically, refer to Figure 4 The display screen 20 is located on the side of the slide plate 2 away from the substrate 1. The slide plate 2 abuts against the display screen 20. At least one substrate 1 is connected to the display screen 20 to drive the display screen 20 to fold. At least one substrate 1 is connected to the display screen 20, and two substrates 1 are rotatably connected at one end in the width direction, thereby driving the display screen 20 to fold (e.g., connected to the display screen 20 via a connecting structure). The display screen 20 is located on one side of the two substrates 1 in the thickness direction and is spaced apart from both substrates 1. Therefore, when the two substrates 1 rotate relative to each other, interference with the folding of the display screen 20 is avoided.

[0068] It can be understood that the two sliding plates 2 are respectively arranged on the side of the two substrates 1 in the thickness direction and face the display screen 20, and the two sliding plates 2 are in abutment with the display screen 20, so that the sliding plate 2 can support the display screen 20. The two sliding plates 2 are movable along the width direction of the two substrates 1, for example, as shown in Figure 5 When the two sliding plates 2 move towards each other, the display screen 20 changes from the folded state to the flat state, and the side of the two sliding plates 2 in the width direction is in abutment, so that the gap between the two sliding plates 2 is reduced, avoiding the display screen 20 from collapsing in the gap between the two sliding plates 2, and ensuring the display effect of the display screen 20. For example, as shown in Figure 5 When the two sliding plates 2 move away from each other, the display screen 20 changes from the flat state to the folded state, and the gap between the two sliding plates 2 is increased, thereby providing space for the folding of the display screen 20, so that the folding of the display screen 20 can be avoided.

[0069] According to the display screen assembly 100 of the embodiment of the present application, by arranging the driving assembly 10, one end of the two substrates 1 is rotationally connected in the width direction, the two sliding plates 2 are arranged on the same side of the two substrates 1 in the thickness direction, the two sliding plates 2 are movable along the width direction of the two substrates 1, the driving shaft 31 extends along the length direction of the substrate 1, and one driving shaft 31 is used to simultaneously drive the two sliding plates 2 to move and drive the two substrates 1 to relatively rotate, so that the structure can be simplified and the cost can be reduced in the case of realizing the driving of the display screen 20 by the driving assembly 10.

[0070] The seat 1000 according to the embodiment of the present application will be described below with reference to Figure 5 .

[0071] As shown in Figure 5 , the seat 1000 according to the embodiment of the present application comprises a seat body 200 and the above-mentioned display screen assembly 100. The seat body 200 is provided with an armrest, and the display screen assembly 100 is arranged on the armrest. It can be understood that the display screen 20 is arranged on the armrest, so that the user can be facilitated to enjoy and adjust the seat 1000, and the user's riding experience is improved. In the prior art, the display screen on the armrest cannot be folded, but in order to enable the user to better watch the display screen, the display screen is usually adjusted by rotating the display screen to enable the user to better watch the display screen. However, the rotation of the display screen will cause a large gap and a gap to be formed between the display screen and the armrest after the display screen is rotated, and the angle of the display screen is limited.

[0072] In the utility model, the angle adjustment of the display screen 20 is realized by folding the display screen 20, so that a large gap is not formed between the display screen 20 and the armrest, the angle of the display screen 20 is more free, and the angle of the display screen 20 is adjusted, so that the display screen 20 is better adapted to different users.

[0073] In some embodiments of the utility model, as shown in the figure, ​ It can be understood that, by the constant ratio of the folding angle of the display screen 20 to the angle adjustment of the backrest 300, when the display screen 20 is folded, the linkage of the angle adjustment of the backrest 300 can be triggered, so that the user can better view and use the display screen 20, for example, in the example shown in the figure, ​ As shown in the figure, the position of the display screen 20 is a1, the position of the backrest 300 is b1, when the display screen 20 is folded to the position a2, the position of the backrest 300 is b2.

[0074] For example, in the utility model, the ratio of the folding angle of the display screen 20 to the angle adjustment of the backrest 300 is 3:1, for example, when the folding angle of the display screen 20 is 60°, the angle adjustment of the backrest 300 is 20°.

[0075] When the display screen 20 and the seat body 200 are in the linkage mode, the user can operate any of the display screen 20 and the seat body 200 to complete the linkage control of the display screen 20 and the seat body 200, so that the operation distance and the line of sight distance are relatively consistent, and the purpose of improving the user experience is achieved. In the linkage mode, when the user operates the display screen 20 to control, the signal is sent to the driving assembly 10 and the seat area controller through the display screen 20 processor, the seat area controller controls the backrest 300 adjustment motor to realize adjustment. Similarly, when the user operates the seat physical button to control, the linkage signal is sent to the backrest 300 adjustment motor and the display screen 20 processor through the seat area controller, and the display screen 20 processor controls the driving assembly 10 to realize adjustment.

[0076] According to the seat 1000 of the utility model embodiment, by setting the display screen assembly 100, setting the driving assembly 10, the two base plates 1 are rotatably connected at one end in the width direction, the two sliding plates 2 are arranged on the same side in the thickness direction of the two base plates 1, the two sliding plates 2 are movable along the width direction of the two base plates 1, the driving shaft 31 extends along the length direction of the base plate 1, and one driving shaft 31 is used for simultaneously driving the two sliding plates 2 to move and driving the two base plates 1 to relatively rotate, so that the structure is simplified and the cost is reduced in the case that the driving assembly 10 drives the display screen 20 to fold.
