[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. For example, those skilled in the art will understand that the features in the various embodiments of the present disclosure can be combined with each other, and the combined implementation methods still fall within the scope of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by people with ordinary skills in the field to which this disclosure belongs. The words "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0037] Figure 1 shows a schematic diagram of a screen assembly according to the present application. The screen assembly 1 is mounted to the truss of an escalator. The escalator includes a head section located at each end of the escalator, an inclined section located in the middle of the escalator, and a transition section connecting the inclined and head sections. The screen assembly is mounted to the inclined, transition, and head sections to face outward and display images. The screen assembly includes a plurality of first screens 11 having a rectangular shape. Each first screen has a first dimension along a first direction and a second dimension along a second direction. The first direction is the direction of extension of the escalator's inclined section, represented by the x-axis in the figure, and the second direction is perpendicular to the first direction, represented by the y-axis in Figure 1. In this example, the first screens 11 have a rectangular shape, with the first dimension being larger than the second dimension. For example, the first dimension is 320 mm and the second dimension is 160 mm. The first screens may be curved screens. However, the first screens may also be square in shape, with the first dimension equal to the second dimension. The first screens may be selected based on the dimensions of the escalator's inclined section. Some of the plurality of first screens 11 are arranged along the first and second directions to form a first screen pattern. This first screen pattern is disposed within the inclined section of the escalator and is preferably configured to completely fill the entire inclined section. However, it is also conceivable that, if the first screen pattern does not completely fill the entire inclined section, a screen smaller than the first screen can be used to occupy the remaining portion of the inclined section, thereby completely filling the inclined section together with the first screen. In other words, the inclined section includes at least the plurality of first screens, in which case the plurality of first screens completely fill the entire inclined section.

[0038] The screen arrangement also includes a plurality of second screens 12 having a rectangular shape, each second screen having a third dimension along the first direction and a fourth dimension along the second direction, the third dimension being smaller than the first dimension, and the fourth dimension being smaller than the second dimension. In this example, the second screens are square in shape, and therefore the third dimension is equal to the fourth dimension. For example, the third dimension and the fourth dimension are 80 mm. However, the second screens may also be rectangular in shape, with the third dimension being larger than the fourth dimension. The selection of the second screens can be based on the dimensions of the transition section and the head section of the escalator, as well as the dimensions of the first screens.

[0039] The remaining first screens from the plurality of first screens 11 and the plurality of second screens are arranged along the first and second directions to form a second screen pattern. This second screen pattern is provided in the transition section and the head section of the escalator, leaving a plurality of blank corner areas 13 in the transition section and the head section. Each blank corner area 13 is inaccessible to second screens along the first and second directions. In other words, in the transition section and the head section of the escalator, the first and second screens, combined, occupy the majority of the transition section and the head section, leaving only blank corner areas inaccessible to second screens along the first and second directions. It should be understood that the location and size of the blank corner areas may vary depending on the size of the first and second screens, but in either case, the blank corner areas are inaccessible to second screens.

[0040] In addition, there may be a plurality of third screens having irregular shapes, and the shape of each third screen is configured to match the shape of the corresponding blank corner area, thereby covering the blank corner area.

[0041] Furthermore, a fourth screen can be included. This fourth screen also has a rectangular shape, but its dimensions along the first and second directions are smaller than the third and fourth dimensions of the second screen, respectively. This allows the fourth screen to be installed in the empty corner area. However, some empty corner areas along the first and second directions will still remain, where the fourth screen cannot be installed. Therefore, those skilled in the art can envision smaller screens to occupy the empty corner areas as needed.

[0042] The screen assembly 1 also includes a support mechanism configured to support a plurality of first screens and a plurality of second screens. The support mechanism is spaced apart from the truss and fixedly mounted to the truss. The support mechanism includes an inclined support mechanism 14, as shown in FIG2 . The shape of the inclined support mechanism 14 corresponds to the shape of the inclined segment and supports the first screen pattern. The inclined support mechanism 14 includes a first inclined portion 141, fixedly mounted to the truss. The mechanism comprises a first rectangular frame 1411 and a plurality of support tubes 1412 extending along a second direction within the first rectangular frame. The tubes of the first rectangular frame are smaller than the dimensions of each support tube, however, this is merely exemplary. A second inclined portion 142, covering the first inclined portion and fixedly mounted to the first inclined portion 141, includes a plurality of mounting openings 1424, the number of which is equal to the number of first screens in the first screen pattern, so that each first screen can be mounted in a corresponding mounting opening. In one example, the second inclined portion is in the form of a planar plate with the plurality of mounting openings 1424 formed therein. In other words, the plurality of mounting openings is hollowed out in the planar plate. The flat plate is preferably metal, with each screen attached to the metal flat plate via magnets at the corresponding mounting opening. However, the flat plate can also be non-metallic, with each screen attached to the non-metallic flat plate via other fixing methods (e.g., bolts). Alternatively, if the flat plate is non-metallic, mounting openings can be cut out of the non-metallic flat plate and the screens can be mounted within the mounting openings, but the screens can be attached to the metal tubes of the first rectangular frame using magnets. In another example, the second inclined portion comprises a second rectangular frame 1421 and a plurality of horizontal tubes 1422 and a plurality of vertical tubes 1423 within the second rectangular frame. The horizontal tubes extend in a first direction, and the vertical tubes extend in a second direction. The horizontal tubes and vertical tubes intersect to form a plurality of mounting openings 1424, the number of which equals the number of first screens in the first screen pattern, so that each first screen can be mounted in a corresponding mounting opening. For example, the first screens may have magnetic members and are supported and mounted in the mounting openings by the magnetic members. Figure 2 illustrates the tilt support mechanism in conjunction with the above two examples.

[0043] An example of the first inclined portion and the second inclined portion is described above, but it should be understood that the inclined support mechanism including the first inclined portion and the second inclined portion is only used to mount the screen to the truss. Those skilled in the art may also conceive of other forms of inclined support mechanisms as long as the screen can be mounted.

[0044] The support structure also includes an end support mechanism 15. As shown in Figure 3, the shape of this end support mechanism 15 corresponds to that of the transition section and the head section, and supports the second screen pattern. End support mechanism 15 includes a first end portion 151, fixedly mounted to the truss. It has a first end frame 1511, within which are arranged a plurality of support tubes 1512 extending in the second direction. The tubes in first end frame 1511 are smaller than the dimensions of each support tube within the first end frame, however, this is merely exemplary. First end frame 1511 is spliced ​​and fixed to the first rectangular frame, with the tubes of the first end frame spliced ​​and fixed to the first rectangular frame extending parallel to the second direction. A second end portion 152, covering first end portion 151 and fixedly mounted thereto, has a plurality of first mounting openings 1524 and a plurality of second mounting openings 1525. The number of the first mounting openings is equal to the number of first screens, so that each first screen can be mounted in a corresponding first mounting opening. The second mounting openings are configured to accommodate multiple second screens. In one example, the second end portion is in the form of a planar plate with a plurality of first and second mounting openings formed therein. That is, the first and second mounting openings are hollowed out in the planar plate. The planar plate is preferably metal, with each screen attached to the metal planar plate at the corresponding mounting opening via magnets. However, the planar plate may also be non-metallic, with each screen secured to the non-metallic planar plate via other fixing methods (e.g., bolts). Furthermore, if the planar plate is non-metallic, mounting openings may be hollowed out in the non-metallic planar plate, with the screens mounted within the mounting openings, but magnets may be used to attach the screens to the metal tubes of the first end frame. In another example, the second end portion 152 includes a second end frame 1521 and, within the second end frame, a plurality of horizontal tubes 1522 and a plurality of vertical tubes 1523. The horizontal tubes 1522 extend in a first direction, while the vertical tubes 1523 extend in a second direction. The horizontal and vertical tubes intersect to form a plurality of first mounting openings 1524. In this example, multiple tubes are further arranged within the second end frame to form multiple second mounting openings. These tubes extend in the first direction and the second direction, are spliced ​​together, and are fixed to adjacent horizontal tubes and / or vertical tubes. FIG3 illustrates the end support mechanism in combination with the above two examples.

[0045] An example of the first end portion and the second end portion is described above, but it should be understood that the end support mechanism including the first end portion and the second end portion is only used to mount the screen to the truss. Those skilled in the art can also conceive of other forms of end support mechanisms as long as the screen can be mounted.

[0046] As shown in Figure 4, the support mechanism is fixedly mounted to the truss of the escalator via a plurality of bracket mechanisms 16, each bracket mechanism is accommodated in the space between the truss and the support mechanism, so that no additional space is required to install the bracket mechanism, each bracket mechanism 16 includes a C-shaped member 161, which is fixedly mounted to the truss and extends along a first direction; a first bracket 162 is fixedly mounted in the C-shaped opening of the C-shaped member; a second bracket 163 is fixedly mounted to the first bracket 162 on the one hand, and fixedly mounted to the support mechanism on the other hand, preferably mounted to the first inclined portion 141 and the first end portion 151.

[0047] FIG. 5 is a schematic diagram showing the C-shaped member 161 fixedly mounted to the truss 2 , and FIG. 6 is a cross-sectional view taken along line X1 - X1 of FIG. 5 .

[0048] As shown in Figures 7(a) and 7(b), the first bracket 162 has a first flat plate 1621 in a first plane and a second flat plate 1622 in a second plane perpendicular to the first plane. The first plane is parallel to the first direction and the second direction, the second plane is parallel to the second direction and the third direction, and the third direction is perpendicular to the first direction and the second direction. In Figure 7, axis z indicates that a first elongated hole 1623 is provided on the second flat plate.

[0049] As shown in FIG8( a ) and FIG8 ( b ), the second bracket 163 has a third flat plate 1631 in the second plane. The third flat plate is parallel to the second flat plate. A second elongated hole 1632 is provided on the third plane.

[0050] One of the first elongated hole 1623 and the second elongated hole 1632 extends along the second direction, and the other of the first elongated hole and the second elongated hole extends along the third direction. In this example, the first elongated hole 1623 extends along the third direction, and the second elongated hole 1632 extends along the second direction.

[0051] The third plate 1631 and the second plate 1622 are fixed together by bolts passing through the first elongated hole 1623 and the second elongated hole 1632, thereby enabling the position of the support mechanism to be adjusted in the second and third directions. In addition, since the C-shaped member extends along the first direction, the position of the support mechanism can also be adjusted in the first direction.

[0052] The screen device also includes a plurality of power supply boxes 17, as shown in Figure 9, each power supply box 17 is fixedly mounted to a support mechanism, such as the first inclined portion 141 and the first end portion 151, via a box bracket 171. As shown in Figure 10, the power supply box 17 is disposed in the space between the truss 2 and the support mechanism. In the case where a dustproof plate is mounted to the truss, the power supply box 17 is disposed between the dustproof plate and the support mechanism. In this case, the truss in Figure 10 is replaced by the dustproof plate. Each power supply box 17 is configured to supply power to a predetermined number of first screens and / or second screens, as shown in Figure 12. Those skilled in the art should understand that what is shown in Figure 12 is merely exemplary, and that a suitable number of power supply boxes can be used to supply power to the first screen and / or second screen as needed.

[0053] The screen device also includes multiple receiving cards 18. Similar to a power supply box, each receiving card 18 is fixedly mounted to a support structure, such as the first inclined portion 141 and the first end portion 151, via a card bracket 181. Each receiving card 18 is positioned in the space between the truss 2 and the support structure. As shown in Figure 11, if a dust shield is attached to the truss, the receiving card 18 is positioned between the dust shield and the support structure. In this case, the truss in Figure 11 is replaced by the dust shield. Each receiving card is connected to a predetermined number of first and / or second screens and is configured to provide the screens with images to be displayed.

[0054] The screen device further includes a plurality of decorative panels (not shown) configured to respectively cover the plurality of blank corner areas, and the decorative panels are flush with the screen to provide an aesthetically pleasing appearance.
