DETAILED DESCRIPTION

[0073] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0074] In the drawings, the size of the constituent elements, the thickness of the layer or the area may be exaggerated for the sake of clarity. Therefore, any implementation of the present disclosure is not necessarily limited to the size shown in the drawings, and the shapes and sizes of the components in the drawings do not reflect the true proportions. In addition, the drawings schematically show ideal examples, and any implementation of the present disclosure is not limited to the shapes or values ​​shown in the drawings.

[0075] Naked-eye 3D display is a new type of display carrier that has emerged recently. The objects in the picture can be protruding from the screen or hidden deep in the screen. It has the characteristics of bright colors, distinct layers, vividness and lifelikeness. It is a true three-dimensional stereoscopic image. Naked-eye stereoscopic images are deeply favored by consumers for their real and vivid expression, beautiful and elegant environmental appeal, and strong and shocking visual impact. However, due to the large size of naked-eye 3D display products, the total weight can reach a maximum of 45kg, which makes the structural strength requirements of naked-eye 3D display modules higher, and requires a higher backplane strength to support the naked-eye 3D display module.

[0076] In view of this, an embodiment of the present application proposes a backplane assembly. Figure 1 FIG. 1 shows a schematic diagram of the top view distribution of the bottom plate reinforcement ribs on the second surface of the bottom plate proposed in one embodiment of the present application, such as Figure 1 As shown, the backplane assembly includes a backplane body, and the backplane body is used to support other functional structures in the backplane assembly. The backplane body includes a bottom plate, and the bottom plate includes a first surface and a second surface arranged opposite to each other, the first surface is a side surface of the bottom plate close to the functional structure, and the second surface is a side surface of the bottom plate away from the functional structure. Since the backplane body needs to provide sufficient supporting strength for the backplane assembly and the display device, a plurality of bottom plate reinforcing ribs are arranged on the second surface of the bottom plate, and the bottom plate reinforcing ribs are formed by protruding from the first surface to the second surface. In order to maximize the strength of the backplane assembly, the bottom plate reinforcing ribs extend in two different directions to form a cross distribution. Specifically, the bottom plate reinforcing ribs include first reinforcing ribs and second reinforcing ribs, the first reinforcing ribs are arranged at intervals along the first direction, and the second reinforcing ribs are arranged at intervals along the second direction, and the second direction intersects with the first direction. Optionally, in order to ensure the strength of the bottom plate reinforcing ribs, the extension direction of the bottom plate reinforcing ribs is consistent with the transmission direction of the force on the bottom plate. Exemplarily, the backplane body is a rectangular structure, and the first direction is the width direction of the rectangle (with Figure 1 For example, the first direction is the vertical direction), and the second direction is the length direction of the rectangle (in Figure 1 For example, the second direction is a vertical direction), thereby ensuring that the first reinforcing ribs and the second reinforcing ribs are distributed perpendicular to each other.

[0077] In the embodiment of the present application, the first reinforcing rib extends on the bottom plate to the edge of the second plane of the bottom plate along the second direction; the second reinforcing rib extends on the bottom plate to the edge of the second plane of the bottom plate along the first direction.

[0078] Since the first reinforcing ribs and the second reinforcing ribs are arranged crosswise, the first reinforcing ribs will divide the second reinforcing ribs into multiple rows of sub-reinforcing ribs. When the two adjacent rows of sub-reinforcing ribs corresponding to the same second reinforcing rib coincide with the intersection of the first reinforcing ribs between the two adjacent rows of sub-reinforcing ribs (i.e., the two adjacent rows of sub-reinforcing ribs are aligned), the strength of the backboard body (e.g., safety factor, normal stress, and deformation, etc.) is relatively low. Therefore, in the embodiment of the present application, the two adjacent rows of sub-reinforcing ribs are arranged in a staggered distribution, and the two adjacent rows of sub-reinforcing ribs corresponding to the same second reinforcing rib do not coincide with the intersection of the first reinforcing ribs between the two adjacent rows of sub-reinforcing ribs, thereby further improving the strength of the backboard body.

[0079] In an embodiment of the present application, under the premise of the same material, the same thickness, and the same bottom plate reinforcement rib height / width, the back plate strength corresponding to the second reinforcement ribs with aligned sub-reinforcements and the second reinforcement ribs with staggered sub-reinforcements are tested respectively, and the back plate strength is evaluated by the minimum safety factor, the maximum paradigm stress, and the maximum deformation. Table 1 shows a back plate strength data table with different arrangements of sub-reinforcements. As shown in Table 1, the second reinforcement ribs with staggered sub-reinforcements are optimized by 253.72% / 254.40% / 227.17% in the three dimensions of safety factor / paradigm stress / deformation compared to the second reinforcement ribs with aligned sub-reinforcements, and the optimization range is significant. Therefore, by setting the distribution of the sub-reinforcements to a staggered distribution, the back plate strength can be significantly improved.

[0080] Table 1 Backboard strength data with different arrangements of sub-reinforcement ribs

[0081] Sub-reinforcement rib arrangement Minimum safety factor Maximum Paradigm Stress (MP) Maximum deformation (mm) Alignment 1.88 99.65 2.09 Dislocation 4.77 39.17 0.92 Optimization range 253.72％ 254.40％ 227.17％

[0082] In some optional embodiments, in order to ensure that the bottom plate reinforcement ribs can evenly transmit the stress borne on the bottom plate, the bottom plate reinforcement ribs are evenly distributed on the bottom plate. Specifically, since the first direction and the second direction are the transmission directions of the force on the backplane assembly, the straight line passing through the center of the bottom plate and extending along the first direction is taken as the first symmetry axis, and the straight line passing through the center of the bottom plate and extending along the second direction is taken as the second symmetry axis. The first reinforcement ribs are respectively arranged in an axisymmetric manner about the first symmetry axis and the second symmetry axis; the multiple rows of sub-reinforcement ribs included in the second reinforcement ribs are respectively arranged in an axisymmetric manner about the first symmetry axis and the second symmetry axis.

[0083] In some optional embodiments, the multiple rows of sub-reinforcement ribs corresponding to each second reinforcement rib include sub-reinforcement ribs located in odd rows and sub-reinforcement ribs located in even rows, wherein, for the same second reinforcement rib, the sub-reinforcement ribs located in odd rows all extend along the second direction on the first straight line, and the sub-reinforcement ribs located in even rows all extend along the second direction on the second straight line, and the first straight line does not overlap with the second straight line.

[0084] In some optional embodiments, in order to prevent the bottom plate reinforcing ribs from excessively compressing the positions of other structures on the back plate assembly, the number of the bottom plate reinforcing ribs on the second surface cannot be too large. Figure 1 As shown, the bottom plate reinforcement ribs include two first reinforcement ribs and four second reinforcement ribs, the number of the first reinforcement ribs is less than the number of the second reinforcement ribs, and the spacing width between adjacent first reinforcement ribs is greater than the spacing width between adjacent second reinforcement ribs. The first reinforcement rib divides each second reinforcement rib into a first sub-reinforcement rib, a second sub-reinforcement rib and a third sub-reinforcement rib, wherein, for multiple sub-reinforcements corresponding to the same second reinforcement rib, the extension direction of the first sub-reinforcement rib and the extension direction of the third sub-reinforcement rib are on the same straight line, and the second sub-reinforcement rib is staggered relative to the first sub-reinforcement rib in the direction away from the center of the bottom plate, that is, the second sub-reinforcement rib is arranged between the first sub-reinforcement rib and the target edge, and the target edge is the bottom plate edge close to the first sub-reinforcement rib and extending along the first direction. It should be noted that, for multiple second reinforcement ribs with the same target edge, the corresponding second sub-reinforcements are arranged in sequence according to the arrangement order of the first sub-reinforcement ribs, and the spacing width between adjacent first sub-reinforcements is the same as the spacing width between adjacent second sub-reinforcements.

[0085] In addition, at least one wall-mounted column is provided on the second surface of the bottom plate provided in the embodiment of the present application, and the wall-mounted column is used to fix the back plate assembly on the wall. In order to ensure the strength of the back plate assembly, each of the wall-mounted columns is connected to a second reinforcing rib.

[0086] In some optional embodiments, in order to maximize the optimization range of the deformation of the bottom plate reinforcement rib, the width of the bottom plate reinforcement rib along the second direction is greater than or equal to 25mm. The corresponding relationship between the width of the bottom plate reinforcement rib and the optimization range of the deformation in the embodiment of the present application is determined according to the following scheme: select a plate with an area of ​​440mm×300mm, set a 1.2t EGI plate, evenly distribute three bottom plate reinforcement ribs extending in the vertical direction along the force transmission direction, ensure that the center position of the bottom plate reinforcement rib remains unchanged, and change the width of the bottom plate reinforcement rib in turn; take the bottom plate reinforcement ribs of each width as the target model in turn, ensure that one end of the target model is fixedly constrained, and load 10N positive pressure on the other end of the target model to obtain the corresponding relationship between the plate deformation and the reinforcement rib width corresponding to each width of the bottom plate reinforcement rib. Table 2 shows a data table of simulation results of the relationship between the bottom plate reinforcement rib width and deformation. As shown in Table 2, when the width of the bottom plate reinforcement rib along the second direction is greater than or equal to 25 mm, the optimization amplitude of the reinforcement rib deformation is stabilized at more than 98%, and the optimization amplitude slows down, thereby determining that the optimal width range of the bottom plate reinforcement rib is greater than or equal to 25 mm.

[0087] Table 2 Simulation results of the relationship between the width of the bottom plate reinforcement and the deformation

[0088]

[0089] In some optional embodiments, in order to maximize the optimization range of the deformation of the bottom plate reinforcement rib, the height of the bottom plate reinforcement rib along the third direction is greater than or equal to 5mm, and the third direction is a direction perpendicular to the second surface. The corresponding relationship between the height of the bottom plate reinforcement rib and the optimization range of the deformation in the embodiment of the present application is determined according to the following scheme: select a plate with an area of ​​440mm×300mm, set a 1.2t EGI plate, evenly distribute three bottom plate reinforcement ribs extending in the vertical direction along the force transmission direction, ensure that the center position of the bottom plate reinforcement rib remains unchanged, and change the height of the bottom plate reinforcement rib in turn; take the bottom plate reinforcement ribs of each height as the target model in turn, ensure that one end of the target model is fixedly constrained, and load 10N positive pressure on the other end of the target model to obtain the corresponding relationship between the plate deformation and the reinforcement rib height corresponding to each height of the bottom plate reinforcement rib. Table 3 shows a data table of simulation results of the relationship between the bottom plate reinforcement rib height and deformation. As shown in Table 3, when the height of the bottom plate reinforcement rib along the third direction is greater than or equal to 5 mm, the optimization range of the reinforcement rib deformation is stabilized at more than 99%, and the optimization range slows down, thereby determining that the optimal height range of the bottom plate reinforcement rib is greater than or equal to 5 mm.

[0091]

[0092] In the embodiment of the present application, Figure 2 FIG. 1 shows a top view of the distribution of the upper side plate reinforcement ribs of a back plate body proposed in an embodiment of the present application. Figure 2 As shown, the back panel body also includes a side panel surrounding the periphery of the bottom panel, the side panel includes a first side panel, a second side panel, a third side panel and a fourth side panel, the first side panel is arranged opposite to the second side panel, the third side panel is arranged opposite to the fourth side panel, Figure 2 For example, the first side panel is the left side panel, the second side panel is the right side panel, the third side panel is the upper side panel, and the fourth side panel is the lower side panel. The bottom panel and the side panel cooperate to form a receiving space, and the receiving space is used to prevent other functional structures of the back panel assembly (such as optical films, etc.), the first surface of the bottom panel faces the receiving space, and the bottom panel reinforcement rib protrudes toward the side away from the receiving space.

[0093] In order to further improve the backplane strength of the backplane assembly and prevent the side panels from becoming the bottleneck of the strength of the entire backplane assembly, the present application sets side panel reinforcement ribs on the side panels, such as Figure 2 As shown, the position of the side panel reinforcement rib corresponds to the bottom panel reinforcement rib on the second surface one by one, as the bottom panel reinforcement rib is extended on the side panel, wherein, since the bottom panel reinforcement rib extends to the bottom panel edge along the first direction and the second direction, the first side panel, the second side panel, the third side panel and the fourth side panel are all provided with side panel reinforcement ribs at positions corresponding to the end points of the extension of the bottom panel reinforcement ribs. Specifically, the side panel includes a first edge close to the periphery of the bottom panel and a second edge opposite to the first edge, the side panel reinforcement rib includes a first end and a second end, the first end is connected to the bottom panel reinforcement rib at the first edge, and the height of the side panel reinforcement rib along the fourth direction gradually decreases from the first end to the second end, and the fourth direction is a direction perpendicular to the side panel plane where the side panel reinforcement rib is located.

[0094] In the embodiment of the present application, at least one limiting portion is provided on the fourth side panel, and the limiting portion is used to mark the position of the XPCB fixing foam, so the side panel reinforcement ribs of the first side panel, the second side panel and the third side panel are arranged in the same manner, and are different from the side panel reinforcement ribs of the fourth side panel. In the embodiment of the present application, the side panel reinforcement ribs of the first side panel, the second side panel and the third side panel are arranged in detail by taking the first side panel as an example, and the second side panel and the third side panel can refer to the arrangement of the first side panel.

[0095] Figure 3 A schematic diagram of the regional structure of the side panel reinforcement ribs on a first side panel proposed in an embodiment of the present application is shown. Figure 3As shown, on the first side panel, the second side panel and the third side panel, the first end of the side panel reinforcement rib is connected to the bottom panel reinforcement rib, the first end of the side panel reinforcement rib is located at the position corresponding to the bottom panel reinforcement rib on the first edge, and the second end is located at the second edge, so that the side panel reinforcement rib extends from one side of the side panel to the other side. Since there is no size restriction of other structures on the first side panel, the second side panel and the third side panel, in order to improve the supporting strength of the side panel, the height of the first end of the side panel reinforcement rib along the fourth direction is the same as the height of the bottom panel reinforcement rib along the third direction, and the third direction is a direction perpendicular to the second surface. For example, on the first side panel, the second side panel and the third side panel, the height of the first end of the side panel reinforcement rib along the fourth direction is 5mm. The height of the side panel reinforcement rib along the fourth direction gradually decreases from the first end to the second end with a first variation range until the height of the second end along the fourth direction is 0. Optionally, the first variation range is a linear variation range, so that on the first side panel, the second side panel and the third side panel, the surface of the side panel reinforcement rib away from the side panel is a plane.

[0096] In some optional embodiments, the back panel assembly further includes a support plate, which is used to support the rubber frame. The support plate surrounds the second edge of the side panel, is arranged parallel to the bottom panel, and protrudes from the second edge in a direction away from the bottom panel. Wherein, on the first side panel, the second side panel, and the third side panel, the second end of the side panel reinforcement rib is located at the connection between the support plate and the side panel, and is arranged tangent to the support plate.

[0097] Figure 4 A schematic diagram of the regional structure of the side plate reinforcement ribs on a fourth side plate proposed in an embodiment of the present application is shown, Figure 4 As shown, the fourth side panel is provided with a plurality of limiting parts. Since there is a limiting part among the plurality of limiting parts that at least partially corresponds to the bottom plate reinforcement rib, the extension of the side panel reinforcement rib on the fourth side panel needs to consider avoiding the limiting part. The limiting part described in the embodiment of the present application corresponds to at least partially the bottom plate reinforcement rib, which means that when the bottom plate reinforcement rib continues to extend on the fourth side panel in the extension direction of the bottom plate, it overlaps with the limiting part. Specifically, the side panel reinforcement rib on the fourth side panel includes a third reinforcement rib and a fourth reinforcement rib. The third reinforcement rib is a side panel reinforcement rib on the fourth side panel that extends from the bottom plate reinforcement rib that does not correspond to the limiting part. Since the third reinforcement rib does not need to avoid the limiting part, the third reinforcement rib can extend from the first edge of the side panel to the second edge. Therefore, the second end of the third reinforcement rib is located at the second edge.

[0098] Since the third reinforcing rib is located on the fourth side panel, and other functional structures need to be arranged on the fourth side panel, the height of the third reinforcing rib along the fourth direction cannot be too high to prevent the contour size of the functional structure from being affected. Therefore, the height of the first end of the third reinforcing rib along the fourth direction is less than the height of the bottom plate reinforcing rib along the third direction. Exemplarily, the height of the first end of the third reinforcing rib along the fourth direction is 1.5 mm. The height of the third reinforcing rib along the fourth direction gradually decreases from the first end to the second end with a second variation amplitude until the height of the second end along the fourth direction is 0. Since the height of the first end of the third reinforcing rib is smaller than the height of the first end of the side plate reinforcing rib on the first side panel, the second variation amplitude is less than the first variation amplitude. Optionally, the second variation amplitude is a linear variation amplitude, so that on the fourth side panel, the surface of the third reinforcing rib away from the side panel is a plane.

[0099] In the embodiment of the present application, the fourth reinforcing rib is a side plate reinforcing rib extending from the bottom plate reinforcing rib on the fourth side plate which at least partially corresponds to the limiting portion, so the extension direction of the fourth reinforcing rib on the side plate is occupied by the limiting portion, so in order to protect the structure of the limiting portion, the second end of the fourth reinforcing rib is located on the side of the limiting portion close to the first edge. The height of the first end of the fourth reinforcing rib along the fourth direction is equal to the height of the bottom plate reinforcing rib along the third direction; the height of the fourth reinforcing rib along the fourth direction gradually decreases from the first end to the second end, and the height variation of the fourth reinforcing rib along the fourth direction from the first end to the second end is the same as the first variation. Since the height variation of the fourth reinforcing rib is the same as that of the side plate reinforcing rib of the first side plate, and the extension length (the distance from the first end to the second end) of the fourth reinforcing rib is smaller, the height of the second end of the fourth reinforcing rib along the fourth direction is greater than 0.

[0100] In the embodiment of the present application, by respectively setting side plate reinforcing ribs on each side plate corresponding to the bottom plate reinforcing ribs, the strength of the side plate in the back plate assembly is effectively improved, while ensuring the feasibility of mass production of stamping; at the same time, considering the limiter and other functional structures on the fourth side plate, the structures of the third reinforcing rib and the fourth reinforcing rib on the fourth side plate are designed differently, effectively ensuring the requirements of the product outline size.

When the rivet column is subjected to shear force, it will stretch the bottom plate. In order to protect the bottom plate from deformation due to the shear force, in the embodiment of the present application, the pressure riveting structure is set as a step-type structure protruding away from the second surface. Specifically, the pressure riveting structure includes a first pressure riveting plane and a second pressure riveting plane arranged parallel to the second surface, the first pressure riveting plane is arranged away from the second surface, the first pressure riveting plane and the second pressure riveting plane are connected by a first pressure riveting inclined plane to form a first step; the second pressure riveting plane and the second surface are connected by the second pressure riveting inclined plane to form a second step, and the mounting hole is arranged on the first pressure riveting plane. The present application weakens the stretching effect of the rivet column in the mounting hole on the bottom plate through the second step structure of the pressure riveting structure.

[0102] In the embodiment of the present application, Figure 6 A schematic diagram of a side view of a riveting structure on a back plate body proposed in an embodiment of the present application is shown. Figure 7 FIG. 1 shows an enlarged schematic diagram of an area b on a backplane body proposed in an embodiment of the present application. Figure 6-Figure 7 As shown, when the rivet column is subjected to shear force, in order to disperse the supporting effect of the bottom plate on the rivet column and avoid that the shear force is supported only by the material thickness of the bottom plate, the first pressure riveting plane protrudes toward the side away from the bottom plate at the edge close to the rivet column to form a first flange structure, and the first flange structure fits the side surface of the second part. The first part of the rivet column is arranged between the first pressure riveting plane and the second pressure riveting plane, and the side of the first part close to the first pressure riveting plane fits the first pressure riveting plane, so that the first part protrudes toward the side of the second surface compared with the first pressure riveting plane.

[0103] In some optional embodiments, Figure 8 FIG. 1 shows a schematic diagram of a top view of a first surface of a bottom plate of a back plate body proposed in an embodiment of the present application. Fig. 9 FIG. 1 shows an enlarged schematic diagram of a backplane body region c proposed in an embodiment of the present application. Figure 8-Figure 9 As shown, in order to prevent the bottom plate from being locally deformed due to the shear force borne by the rivet stud at the support of the riveting structure, and to provide a space for the first part of the rivet stud, a first reinforcing plate is provided on the first surface at a position corresponding to the riveting structure, and the orthographic projection of the first riveting plane on the bottom plate is located inside the orthographic projection of the first reinforcing plate on the bottom plate. Figure 5 and Fig. 9 As shown, the first reinforcing plate is arranged on the second riveting plane, and cooperates with the riveting structure and the first part to form a cavity, and the cavity is used to accommodate the first part of the rivet column. Optionally, the first reinforcing plate is fixedly connected to the second riveting plane by a reinforcing plate fastener, and the reinforcing plate fastener can be a threaded fastener, etc.

[0104] In some optional embodiments, Fig.10 A schematic diagram of the structure of a back panel body and a frame assembly proposed in an embodiment of the present application is shown. Fig.11 FIG. 1 shows an enlarged schematic diagram of a back panel body and a frame component area d proposed in an embodiment of the present application, such as Figure 10-11 As shown, the back panel assembly also includes a frame assembly, and the frame assembly is used to be fixedly connected to the back panel body and the display module respectively to fix the display device as a whole. In view of the large base weight of the display device, the frame assembly is connected to the display module and the back panel body by providing a plurality of fasteners. Specifically, the frame assembly is provided with a plurality of first fasteners and a plurality of second fasteners, the first fasteners connect the side panels and the frame assembly, and the second fasteners connect the display module and the frame assembly. Since the first fastener and the second fastener are both arranged on the frame assembly, and the first fastener and the second fastener are devices for connecting different components, the specifications of the first fastener and the second fastener corresponding to the same side panel on the frame assembly are the same, thereby avoiding mixing of fasteners on the frame assembly. It should be noted that the specifications of the first fastener and the second fastener refer to the structure and size of the fasteners, which can also be understood as the first fastener and the second fastener are of the same type, and the models corresponding to this type in the field are also the same. Exemplarily, the first fastener and the second fastener are both rivet structures, and the rivet specifications of the first fastener and the second fastener are both M3*2.9 rivets. The above example is only an optional implementation example. The specific specifications of the first fastener and the second fastener can be determined according to actual conditions, and this application is not limited here.

[0105] In some optional embodiments, since the first fastener and the second fastener on the same side panel of the frame assembly are identical, when the frame assembly is fixedly connected to the back panel body and the display module, the first fastener and the second fastener cannot be distinguished, which may cause the fasteners to be missed or mixed. Fig.11As shown, in the embodiment of the present application, a plurality of fool-proofing structures corresponding one to one with the plurality of first fasteners are arranged on the frame assembly, and the fool-proofing structures are arranged close to the first fasteners. Since the fool-proofing structures are only arranged around the first fasteners, during the installation process, technicians can distinguish the first fasteners and the second fasteners of the same specification according to the positions of the fool-proofing structures, thereby avoiding the risk of mixed installation.

[0106] In some optional embodiments, since no other functional structures are provided on the first side panel, the second side panel and the third side panel, a functional structure needs to be provided on the fourth side panel, so the specifications of the first fasteners on the frame assembly corresponding to the first side panel, the second side panel and the third side panel are the same, and are different from the specifications of the first fasteners corresponding to the fourth side panel. The number of the first fasteners on the frame assembly corresponding to the first side panel, the second side panel and the third side panel is the same, and is less than the number of the first fasteners on the fourth side panel. For example, the number of the first fasteners on the frame assembly corresponding to the first side panel, the second side panel and the third side panel is 8, and the number of the first fasteners corresponding to the fourth side panel is 14.
