[0032] In order to further understand the present application, a further description will be provided in connection with the embodiments.

[0033] In the description and claims of the application, each of the words "comprise" "include" and the like are to be understood in its

[0034] Please refer to Figure 1 and Figure 2 , Figure 1 Exploded view of the light shielding device 10 according to an embodiment of the present application, Figure 2 Assembled view of the light shielding device 10 according to an embodiment of the present application. The light shielding device 10 can include a display screen 12 and a light shielding device 14. The display screen 12 can be a multi-screen combination formed by multiple screens assembled together; Figure 1 The display screen 12 of the shown embodiment includes a first screen 16 and a second screen 18 which can be assembled together by the light shielding device 14. It is to be noted that the number of screens is not limited to two, and can be determined according to actual requirements. The multiple screens of the display screen 12 can be assembled together at any assembly angle, and the light shielding device 14 can be adjusted adaptively according to the assembly angle of the multiple screens of the display screen 12.

[0035] The light shielding device 14 can include a first light shielding member 20, a second light shielding member 22, and a light shielding cover 24. The first light shielding member 20 can be disposed on the left side of the first screen 16, and the second light shielding member 22 can be disposed on the right side of the second screen 18 relative to the first screen 16. The first light shielding member 20 and the second light shielding member 22 are standard light shielding members, each having a side light shielding area 26 and a top light shielding area 28. The side light shielding area 26 can be disposed on the side of the display screen 12, and the top light shielding area 28 is connected between the side light shielding area 26 and the light shielding cover 24. The light shielding cover 24 can be disposed between the first screen 16 and the second screen 18 and connected with the first light shielding member 20 and the second light shielding member 22 to form a complete light shielding device 14. Regardless of the joining angle of the first screen 16 and the second screen 18, the light shielding device 14 can correctly shield the top and both sides of the display screen 12, effectively avoiding the influence of ambient light on the display screen 12 and reducing the image quality.

[0036] Referring to FIG. 1, Figure 3 , Figure 3 FIG. 1 is a schematic diagram of the assembly of a light shielding device 10 according to an embodiment of the present application. The display screen 12 of the light shielding device 10 can include a first screen 16, a second screen 18, and a third screen 30 that are spliced with each other. The third screen 30 can be located between the first screen 16 and the second screen 18. Accordingly, the light shielding device 14 can further include a first light shielding member 20, a second light shielding member 22, a light shielding cover 24, and a third light shielding member 32. The third light shielding member 32 can be disposed on the third screen 30, and thus the third light shielding member 32 is a special light shielding member having only a top light shielding area 28.

[0037] It can be understood that the number of light shielding covers 24 increases with the number of screens of the display screen 12. For example, in the embodiment shown in FIG. 1, the light shielding cover 24 can be disposed between the first screen 16 and the third screen 30 and between the second screen 18 and the third screen 30, so the light shielding device 10 includes two light shielding covers 24. Regardless of the number of screens of the display screen 12 or the joining angle of the adjacent screens of the display screen 12, the light shielding cover 24 of the present application can completely cover the top and both sides of the display screen 12, avoiding the influence of ambient light on the display screen 12 and reducing the image quality. Figure 3 Referring to FIG. 1,

[0038] , Figures 4 to 9 FIG. 2 is a schematic diagram of the appearance of a light shielding cover 24 according to an embodiment of the present application, Figure 4 FIG. 3 is a schematic diagram of the appearance of the light shielding cover 24 in another view according to an embodiment of the present application, and Figure 5 Figure 6 ​This is a schematic diagram of the appearance of a light shield 24 provided in another embodiment of the present invention. Figure 7 This is a schematic diagram of the assembly of the light shield 24 and the display screen 12 provided in an embodiment of the present invention. Figure 8 This is a partial exploded view of the light shield 24 provided in an embodiment of the present invention. Figure 9 This is a schematic diagram of a portion of the structure of the light shield 24 provided in an embodiment of the present invention from other perspectives.

[0039] The light shield 24 may include a bridging member 34, a first top plate 36, and a second top plate 38. The bridging member 34, serving as a structural component connecting two adjacent screens of the display screen 12, may be further divided into a first side plate 40 and a second side plate 42. Figure 1 and Figure 2 Taking the illustrated embodiment as an example, the first side plate 40 and the second side plate 42 are rotatably combined and detachably connected to the first screen 16 and the second screen 18, respectively. The first top plate 36 can be disposed at the top of the first side plate 40, and the second top plate 38 can be disposed at the top of the second side plate 42. Therefore, the first top plate 36 and the second top plate 38 are fixed to different structural components (i.e., the first side plate 40 and the second side plate 42), so the first top plate 36 can move closer to or further away from the second top plate 38 as the first side plate 40 and the second side plate 42 rotate relative to each other.

[0040] Furthermore, the second top plate 38 can be a stepped structure composed of a first segment 44 and a second segment 46. The second top plate 38 can overlap the first top plate 36 with the first segment 44 so that the second segment 46 can be flush with the first top plate 36. Therefore, the second top plate 38 can partially overlap the first top plate 36 to accommodate the relative rotation between the first side plate 40 and the second side plate 42. It should be noted that the shape, area ratio, and stepped depth of the first segment 44 and the second segment 46 are not limited to the form shown in this embodiment, and can be determined according to design requirements. Other possible variations will not be described separately here.

[0041] like Figure 5 As shown, the first side plate 40 may include multiple first engaging portions 48, and the second side plate 42 may include multiple second engaging portions 50. The first engaging portions 48 may have protruding structures, while the second engaging portions 50 may have corresponding recessed structures; alternatively, the first engaging portions 48 may have recessed structures, while the second engaging portions 50 may have corresponding protruding structures. It should be noted that the style, size, and connection method of the protruding and recessed structures can be determined according to design requirements. For example, the first engaging portion 48 may be designed with a pin as a protruding structure, while the second engaging portion 50 may be designed with a shaft hole as a recessed structure. The first engaging portion 48 is rotatably inserted into the shaft hole (recessed structure) via the pin (protruding structure) to movably engage with the adjacent second engaging portion 50, thereby allowing the first side plate 40 and the second side plate 42 to rotate freely relative to each other.

[0042] It is worth mentioning that when the first engaging portion 48 is engaged with the second engaging portion 50, the first engaging portion 48 is spaced apart from the second engaging portion 50 by a predetermined distance D, i.e. the width of the first engaging portion 48 is slightly less than the width of the second engaging portion 50, so that the first side plate 40 and the second side plate 42 can be relatively rotated and translated. The width refers to the dimension of the first engaging portion 48 and the second engaging portion 50 along the arrangement direction thereof (or the length direction of the first side plate 40 and the second side plate 42). In other words, the first side plate 40 and the second side plate 42 can be rotated along the first direction Dl and translated along the second direction D2 by the combination of the first engaging portion 48 and the second engaging portion 50.

[0043] Alternatively, as shown in another embodiment, Figure 6 each first engaging portion 48 can have a first through hole 52, and each second engaging portion 50 can have a second through hole 54. The bridge 34 can further include a connecting shaft 56. The connecting shaft 56 is used to pass through the first through hole 52 and the second through hole 54, so that the first engaging portion 48 can be engaged with the adjacent second engaging portion 50. In this embodiment, the width of the first engaging portion 48 is preferably still slightly less than the width of the second engaging portion 50, so that the first side plate 40 and the second side plate 42 can be relatively rotated along the first direction Dl and translated along the second direction D2.

[0044] As shown in Figure 7 , the first side plate 40 and the second side plate 42 can each have a hook portion 58, and the display screen 12 has a corresponding recess portion 60. The structural height of the first side plate 40 (and / or the second side plate 42) is approximately equal to the structural height of the display screen 12, so that the position of the hook portion 58 corresponds to the position of the recess portion 60, so that when the first side plate 40 (and / or the second side plate 42) is assembled to the display screen 12 by using the hook portion 58 to hold the recess portion 60, the upper and lower ends of the first side plate 40 (and / or the second side plate 42) can be approximately aligned with the upper and lower sides of the display screen 12, avoiding that the light shield 24 excessively protrudes from the first screen 16 and the second screen 18 and affecting the overall appearance of the light shielding device 10.

[0045] It is worth mentioning that the hook portion 58 of the first side plate 40 (and / or the second side plate 42) is a protruding structure extending downwards. The hook portion 58 is inserted downwards into the recessed portion 60, and the light shield 24 is stably attached to the display screen 12 by the gravity of the first side plate 40 (and / or the second side plate 42). If the first side plate 40 and the second side plate 42 each have a recessed portion (not shown in the figure), and the display screen 12 has a corresponding hook portion (not shown in the figure), the hook portion of the display screen 12 is a protruding structure extending upwards; in this way, the recessed portion of the first side plate 40 (and / or the second side plate 42) is inserted downwards into the hook portion of the display screen 12, and the light shield 24 can also be stably attached to the display screen 12 by the gravity of the first side plate 40 (and / or the second side plate 42).

[0046] like Figure 8 As shown, the first top plate 36 and the first side plate 40 (or the second top plate 38 and the second side plate 42) may each have a first fixing part 62 and a second fixing part 64. The first fixing part 62 may be a columnar structure and / or an L-shaped structure, and is disposed at the edge of the first top plate 36 adjacent to the first side plate 40 (or the edge of the second top plate 38 adjacent to the second side plate 42). The second fixing part 64 may be a straight hole and / or a directional hole, and is disposed at the edge of the first side plate 40 adjacent to the first top plate 36 (or the edge of the second side plate 42 adjacent to the second top plate 38). One set of the first fixing part 62 and the second fixing part 64 are designed as an L-shaped structure and a directional hole, respectively, which can simultaneously restrict the degrees of freedom of the first top plate 36 relative to the first side plate 40 (or the second top plate 38 relative to the second side plate 42) in different directions, such as restricting longitudinal and lateral movement. The other set of first fixing part 62 and second fixing part 64 are designed as columnar structures and straight holes, respectively, which can only restrict the first top plate 36 relative to the first side plate 40 (or the second top plate 38 relative to the second side plate 42) along a single direction of freedom, such as restricting lateral movement, and are auxiliary limiting components.

[0047] like Figure 9 As shown, the first side panel 40 may selectively include a first light-shielding portion 66, disposed on the outer surface of the first side panel 40 facing the second side panel 42; the second side panel 42 may selectively include a second light-shielding portion 68, disposed on the outer surface of the second side panel 42 facing the first side panel 40. Since the first side panel 40 and the second side panel 42 are rotatably connected through the first engaging portion 48 and the second engaging portion 50, there must be a gap between the first engaging portion 48 and the second engaging portion 50 to avoid interference; in order to prevent ambient light from penetrating this gap and affecting the image quality of the display screen 12, the light shield 24 blocks ambient light from outside the first side panel 40 and the second side panel 42 through the first light-shielding portion 66 and the second light-shielding portion 68.

[0048] To improve the light shielding efficiency of the first light shielding portion 66 and the second light shielding portion 68, the first light shielding portion 66 is preferably adjacent to the first engaging portion 48, and the height of the first light shielding portion 66 is equal to or less than the height of the first engaging portion 48; the second light shielding portion 68 is preferably adjacent to the second engaging portion 50, and the height of the second light shielding portion 68 is equal to or less than the height of the second engaging portion 50. If the height of the first light shielding portion 66 is higher than the height of the first engaging portion 48 (or the height of the second light shielding portion 68 is higher than the height of the second engaging portion 50), the first side plate 40 and the second side plate 42 are likely to interfere with each other when closed, so the height of the first light shielding portion 66 is equal to or less than the height of the first engaging portion 48 (or the height of the second light shielding portion 68 is less than the height of the second engaging portion 50), and the partial overlap between the first light shielding portion 66 and the second light shielding portion 68 effectively shields ambient light from the outside of the first side plate 40 and the second side plate 42.

[0049] Please also refer to Figure 9 The first top plate 36 can be provided with a first stop portion 70 adjacent to the outer edge of the second top plate 38, and the second top plate 38 can be provided with a second stop portion 72 adjacent to the outer edge of the first top plate 36. The first stop portion 70 and the second stop portion 72 are used to shield ambient light passing through the gap between the first engaging portion 48 and the second engaging portion 50, so the positions of the first stop portion 70 and the second stop portion 72 can be adjacent to the first engaging portion 48 of the first side plate 40 and the second engaging portion 50 of the second side plate 42, respectively. Generally, the first stop portion 70 is an outward protruding structure, and the second stop portion 72 is a different inward recessed structure; when the first top plate 36 moves relative to the second top plate 38, the first stop portion 70 (outward protruding structure) and the second stop portion 72 (inward recessed structure) can partially interleave with each other, thus shielding ambient light from the outside of the first side plate 40 and the second side plate 42.

[0050] Alternatively, the first stop portion 70 can also be designed as an inward recessed structure, and the second stop portion 72 is designed as a corresponding outward protruding structure; or the first stop portion 70 and the second stop portion 72 are both designed as outward protruding structures. It should be noted that the style, size and combination of the first stop portion 70 and the second stop portion 72 are not limited to the illustrated embodiments, and can be determined according to design requirements. As long as the first stop portion 70 and the second stop portion 72 partially interleave with each other, it belongs to the design scope of the present application.

[0051] In summary, the light shielding cover, the light shielding device and the light shielding equipment provided by the present application shield the upper sides of two adjacent screens by the first top plate and the second top plate respectively, and the bridging piece is connected between the first top plate and the second top plate. The bridging piece is combined by the first side plate and the second side plate which can rotate freely, and the first side plate and the second side plate are connected to the first top plate and the second top plate respectively. Therefore, when the user adjusts the included angle between the two adjacent screens, the first side plate and the second side plate of the bridging piece can be expanded or closed accordingly, and the rotation angle of the two side plates can be adjusted completely according to the change of the included angle between the two adjacent screens. The light shielding cover provided by the present application can be arbitrarily matched with various multi-screen combinations with different numbers of screens and different screen angles, so that the light shielding device and the light shielding equipment can change the screen included angle according to the user's needs.

[0052] The present application has been described by the above-mentioned related embodiments, however, the above-mentioned embodiments are only examples for implementing the present application. It must be pointed out that the disclosed embodiments do not limit the scope of the present application. On the contrary, modifications and improvements made without departing from the spirit and scope of the present application are within the scope of the patent protection of the present application.
