[0041] Through the above-mentioned drawings, specific embodiments of the present invention have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the inventive concept in any way, but to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiment

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention.

[0043] All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0044] The existing manufacturing processes of backplanes often use injection molding and stamping. Among them, injection molding is a molding method that combines injection and molding. However, due to the characteristics of plastics and the limitations of injection molds, its application range is relatively narrow and is generally used for small-sized backplanes;

[0045] In addition, stamping refers to a processing and forming method in which an external force is applied to plates, strips, tubes, profiles, etc. by a press and a die, causing them to undergo plastic deformation or separation, thereby obtaining workpieces with the required shapes and dimensions. However, the cost of the required die is high, the amortization cost of a single material die is high, and the die opening cycle is relatively long. Moreover, the strength of the backplane can only be improved through the material thickness and structural design, and its heat dissipation performance is average. Additionally, when processing backplanes with extremely large dimensions, not only is the processing difficult, but it is also very difficult to ensure its flatness.

[0046] In view of this, multiple small-sized substrates 1 can be provided, and the substrates 1 form a backplane by splicing, so as to overcome the problem of difficult processing of large-sized backplanes. Additionally, the substrates 1 can be manufactured by an extrusion molding method, thereby reducing the cost and difficulty required for processing. Furthermore, reinforcing ribs 12 can be integrally formed on the substrates 1 to improve the strength of the backplane.

[0047] Figure 1 A three-dimensional schematic diagram of a substrate 1 provided for an exemplary embodiment, Figure 2 A cross-sectional view of a substrate 1 provided for an exemplary embodiment, Figure 3 A three-dimensional schematic diagram of a bottom plate provided for an exemplary embodiment, as Figures 1 - 3 shown, a backplane includes: multiple substrates 1, and the multiple substrates 1 are spliced in the same layer to form a bottom plate; a connection assembly, at least part of the connection assembly is arranged at the splicing position of two adjacent substrates 1, and the connection assembly is respectively connected to the two adjacent substrates 1 to connect the two adjacent substrates 1.

[0048] It should be noted that the multiple substrates 1 can be spliced into a bottom plate arranged in a rectangular shape as Figure 3 shown, or can be spliced into other shapes. The shape of the bottom plate is only an example here, and those skilled in the art can design according to the specific structure of the backplane without specific constraints.

[0049] Next, taking Figure 3 the shape of the bottom plate shown, that is, the bottom plate is arranged in a rectangular shape, to describe this solution. Among them, for the convenience of description, the direction indicated by arrow A in the figure is set as the length direction of the substrate 1, the direction indicated by arrow B is set as the width direction of the substrate 1, and the direction indicated by arrow C is set as the thickness direction of the substrate 1. Exemplarily, in Figure 1 and Figure 3 , the multiple substrates 1 are spliced side by side along their width directions to form a bottom plate arranged in a long direction, the width of the bottom plate is equal to the length of the substrate 1, and the length of the bottom plate is the sum of the widths of the multiple substrates 1. A

[0050] Optionally, before fixing two adjacent substrates 1 through the connection assembly, the two substrates 1 can be pre-fixed by inserting, so as to make the connection between the two substrates 1 more stable.

[0051] Understandably, for the base plate provided by the present invention, by providing a plurality of substrates 1, and forming the base plate by splicing the plurality of substrates 1, and connecting adjacent two substrates 1 through a connecting component, the plurality of substrates 1 can form base plates of multiple sizes, which is beneficial to reducing the processing difficulty and processing cost.

[0052] Next, the structure of the substrate 1 will be described.

[0053] Optionally, the substrate 1 is manufactured by an extrusion molding process. Extrusion molding is also known as extrusion forming and plastic forming method. Extrusion molding is also called extrusion in plastic processing. In non-rubber extrusion processing, extrusion using the pressure of a hydraulic press on the mold itself is called pressing out. It refers to a processing method in which materials are plastically melted by the action between the barrel and the screw of an extruder, and are continuously pushed forward by the screw and pass through the die head to form various cross-section products or semi-products.

[0054] Among them, extrusion forming is suitable for producing long-sized rods, tubes, columns, plate-shaped products and other products with consistent cross-sections. The extrusion length is almost unlimited, and various shaped products can be extruded by replacing the extrusion nozzle. Understandably, compared with stamping forming, extrusion forming has the advantages of lower cost and easier processing.

[0055] Optionally, after the substrate 1 is extrusion molded, it can be determined whether to perform additional processing according to actual needs. Such as processing avoidance grooves or threaded holes, etc. It should be noted that when opening threaded holes, as Figure 7 shown, an installation post 14 is provided on the substrate 1, and the installation post 14 extends in a direction away from the substrate 1, and the threaded hole can be provided on the installation post 14 to increase the connection length between the fastener and the substrate 1.

[0056] Optionally, continue to refer to Figures 1 - 3 , one side in the thickness direction of the substrate 1 may be provided with a reinforcing rib 12 to enhance the strength of the substrate 1. Optionally, as Figure 3 shown, the axial direction of the reinforcing rib 12 may be parallel to the length direction of the substrate 1. Among them, a plurality of reinforcing ribs 12 may be provided, and the plurality of reinforcing ribs 12 may be evenly distributed along the width direction of the substrate 1 to further enhance the strength of the substrate 1. In addition, the plurality of reinforcing ribs 12 form a grid structure to facilitate the heat dissipation of the substrate 1. Of course, the axial direction of the reinforcing rib 12 may also be parallel to the width direction of the substrate 1, and the plurality of reinforcing ribs 12 may be evenly distributed along the length direction of the substrate 1. In addition, the reinforcing rib 12 may also be annular or other shapes, and the plurality of reinforcing ribs 12 may also have other various setting methods. Here is just an example and is not specifically limited.

[0057] Optionally, the reinforcing ribs 12 can be provided on one or both sides of the substrate 1, that is, the reinforcing ribs 12 can be provided on both sides in the thickness direction of the substrate 1, or only on one side in the thickness direction of the substrate 1. It should be noted that when the reinforcing ribs 12 are provided on both sides of the substrate 1, the reinforcing ribs 12 on both sides can be arranged in a staggered manner to improve the strength and heat dissipation efficiency of the substrate 1. Optionally, the reinforcing ribs 12 and the substrate 1 can be integrally formed. That is to say, the substrate 1 provided with the reinforcing ribs 12 can be manufactured together by an extrusion process. In this way, compared with injection molding, the substrate 1 formed by extrusion molding has higher strength.

[0058] Optionally, as Figure 1 and Figure 3 shown, the substrate 1 includes a first end and a second end, and a first mounting protrusion 11 is provided at the first end of the substrate 1. The first mounting protrusion 11 is provided on one side in the thickness direction of the substrate 1. Figure 1 and Figure 3 In, the axial direction of the first mounting protrusion 11 extends along the thickness direction of the bottom plate.

[0059] It can be understood that when operating such as wall mounting that requires drilling holes in the backplane, the depth of the holes needs to be long enough to ensure the connection depth and strength. Thus, the thickness of the backplane needs to be greater than or equal to the depth of the holes. And a first mounting protrusion 11 is provided on the substrate 1 to facilitate increasing the local thickness of the backplane, and a threaded hole or a through hole is provided in the first mounting protrusion 11.

[0060] Optionally, the first mounting protrusion 11 and the substrate 1 can also be formed by extrusion and integrally manufactured.

[0061] Optionally, only one first mounting protrusion 11 can be provided on the substrate 1, and the first mounting protrusion 11 can be arranged at one end in the width direction of the substrate 1 as Figure 1 shown; two first mounting protrusions 11 can be provided on the substrate 1, and the two first mounting protrusions 11 can be arranged at the first end and the second end of the substrate 1 respectively; three or more first mounting protrusions 11 can also be provided on the substrate 1. Here is just an example, and the number and arrangement method of the first mounting protrusions 11 are not specifically limited.

[0062] It should be noted that the following uses Figure 1 the arrangement method of the first mounting protrusion 11 shown for illustration, that is, a first mounting protrusion 11 is provided at one end in the width direction of the substrate 1, and the axial direction of the first mounting protrusion 11 is arranged along the length direction of the substrate 1. For other arrangements of the first mounting protrusion 11, reference can be made to the following, and details will not be elaborated here.

[0063] Continuing as Figure 3 shown, the splicing methods of multiple substrates 1 include but are not limited to the following possible implementation methods:

[0064] In one possible implementation, as Figure 3 shown, the second ends of two adjacent substrates 1 are in abutting contact. That is to say, the first end of the substrate 1 is provided with a first mounting protrusion 11, the second end of the substrate 1 is not provided with the first mounting protrusion 11, and the ends of two adjacent substrates 1 without the first mounting protrusion 11 are in abutting contact. Optionally, as Figure 5 shown, the connecting component includes a first connecting member 2, and the first connecting member 2 covers the second ends of two adjacent substrates 1 and is respectively connected to the second ends of two adjacent substrates 1.

[0065] Exemplarily, both ends of the first connecting member 2 respectively cover above the second ends of two adjacent substrates 1, and the first connecting member 2 can be respectively connected to two adjacent substrates 1 through fasteners. It can be understood that the connection between two adjacent substrates 1 is realized by means of the first connecting member 2 and fasteners, and the structure is more stable, which is convenient for disassembly and installation.

[0066] Optionally, the first end of the substrate 1 is provided with a first mounting protrusion 11, the second end of the substrate 1 may be provided with a reinforcing rib 12, and the second end of the substrate 1 may also not be provided with the reinforcing rib 12. Figure 5 Taking the example that the second end of the substrate 1 is provided with a reinforcing rib 12, exemplarily, when the second ends of two adjacent substrates 1 are in abutting contact, the two reinforcing ribs 12 of two adjacent substrates 1 are in abutting contact.

[0067] Figure 6 For Figure 5 a cross-sectional view at the first connecting member, as Figure 8 shown, the first connecting member 2 may include a first connecting section 21 and limiting sections 22 provided at both ends of the first connecting section 21, and the limiting sections 22 can be bent relative to the first connecting section 21 towards the substrate 1. Wherein, the first connecting section 21 covers two adjacent reinforcing ribs 12, and the limiting sections 22 are arranged outside two adjacent reinforcing ribs 12 so as to be used for restricting the displacement of two reinforcing ribs 12 in the width direction of the substrate 1.

[0068] Optionally, Figure 7 For Figure 5 a partial schematic diagram of Figure 7As shown, the first connecting section 21 is respectively provided with second connecting sections 23 at both ends in the length direction of the substrate 1. The second connecting sections 23 respectively cover two abutting reinforcing ribs 12 and are respectively connected to the two reinforcing ribs 12 through fasteners. Exemplarily, when installing the first connecting member 2 onto two adjacent substrates 1, first install the two second connecting sections 23 onto the two adjacent reinforcing ribs 12 through fasteners to determine both ends in the length direction of the first connecting member 2. Then install the first connecting member 21 onto the two adjacent reinforcing ribs 12 through fasteners to enhance the connection between the first connecting member 2 and the two adjacent reinforcing ribs 12. Of course, before connecting the second ends of two adjacent substrates 1 through the first connecting member 2, the two adjacent substrates 1 can be simply pre-fixed by means such as plugging, clamping or bonding first.

[0069] In another possible implementation, as Figure 3 shown, the first mounting protrusions 11 of two adjacent substrates 1 are arranged in abutment. That is to say, when splicing two substrates 1, the ends of the two substrates 1 provided with the first mounting protrusions 11 can be arranged in abutment, and the ends of the two substrates 1 not provided with the first mounting protrusions 11 are arranged in opposite directions.

[0070] Optionally, as Figure 8 shown, the connecting assembly further includes a second connecting member 3. The second connecting member 3 covers the two abutting first mounting protrusions 11, and the second connecting member 3 is respectively connected to the two abutting first mounting protrusions 11. Optionally, the second connecting member 3 can be respectively connected to the two first mounting protrusions 11 by means such as fasteners, bonding, clamping, etc. Figure 3 The connection of the second connecting member 3 to the first mounting protrusion 11 by means of fasteners is shown in

[0071] In yet another possible implementation, as Figure 3 shown, when a plurality of substrates 1 are spliced to form a bottom plate, at least one group of adjacent substrates 1 have their first ends in abutment, and at least one group of adjacent substrates 1 have their second ends in abutment.

[0072] Exemplarily, Figure 3Taking the example of forming a bottom plate by splicing six substrate 1s, the first substrate 1, the second substrate 1, the third substrate 1, the fourth substrate 1, the fifth substrate 1, and the sixth substrate 1 are arranged in sequence along the direction of arrow B. Among them, the second ends (the ends without the first mounting protrusion 11) of the first substrate 1 and the second substrate 1 are spliced; the first ends (the ends with the first mounting protrusion 11) of the second substrate 1 and the third substrate 1 are spliced; the second ends (the ends without the first mounting protrusion 11) of the third substrate 1 and the fourth substrate 1 are spliced; the first ends (the ends with the first mounting protrusion 11) of the fourth substrate 1 and the fifth substrate 1 are spliced; the second ends (the ends without the first mounting protrusion 11) of the fifth substrate 1 and the sixth substrate 1 are spliced.

[0073] It can be understood that through Figure 3 the forming method of the bottom plate shown, there are two columns of structures in the middle position of the bottom plate, and each column is formed by splicing two first mounting protrusions 11. In addition, the bottom plate is symmetrically arranged to ensure the uniformity and aesthetics of the back plate.

[0074] In addition, as Figure 5 shown, the second ends of the first substrate 1 and the second substrate 1, and the second ends of the fifth substrate 1 and the sixth substrate 1 are all connected together by the first connecting member 2. For the second ends of the third substrate 1 and the fourth substrate 1, they can be connected together by the first connecting member 2, as Figure 8 and Figure 9 shown, and can be connected by the second connecting member 3 (specifically refer to the description of the second connecting member 3 below), or the third substrate 1 and the fourth substrate 1 can also be integrally formed by an extrusion process. As Figure 4 shown, the back plate further includes a plurality of side plates 4. The side plates 4 are spliced end to end to form a frame, and the frame is sleeved on the outside of the bottom plate. One end of the side plate 4 is provided with a second mounting protrusion 41. The first mounting protrusion 11 and the second mounting protrusion 41 are in abutting contact.

[0075] Exemplarily, the side plate 4 can be provided with one second mounting protrusion 41, and the second mounting protrusion 41 can be arranged on the side of the side plate 4 close to the bottom plate to be connected with the outer frame 311 mentioned below or the first mounting protrusion 11 mentioned above; Another exemplarily, as Figure 4 shown, the side plate 4 can also be provided with two second mounting protrusions 41. One of the second mounting protrusions 41 can be arranged on the side of the side plate 4 close to the bottom plate. The other second mounting protrusion 41 can be arranged on the side of the side plate 4 away from the bottom plate to improve the uniformity of the side plate 4; Of course, the number of the second mounting protrusions 41 can be three or more. Here is just an example, and the number and arrangement method of the second mounting protrusions 41 are not specifically limited.

[0076] In the following, taking Figure 4The structure of the back panel will be described by taking the arrangement of the second mounting protrusions 41 in it as an example, that is, there are two second mounting protrusions 41, and the two second mounting protrusions 41 are arranged on both sides of the side plate 4 respectively. For other arrangement ways of the second mounting protrusions 41, reference can be made to the following text and will not be elaborated here.

[0077] In addition, "the head and tail splicing of the side plates 4" means that the side plate 4 includes a first end and a second end. Among two adjacent side plates 4, the first end of one side plate 4 is connected to the second end of the other side plate 4. Multiple side plates 4 form a ring so as to surround the outside of the bottom plate.

[0078] Optionally, the cross-section of the side plate 4 is trapezoidally arranged, and the length of the side plate 4 on the side close to the bottom plate is less than the length of the side plate 4 on the side far from the bottom plate. Optionally, two adjacent side plates 4 can be connected together by a third connecting member 5. The third connecting member 5 includes a plate body. The plate body is arranged between the two second mounting protrusions 41. The plate body covers the splicing part of the two adjacent side plates 4 and is respectively connected to the two side plates 4. The third connecting member 5 can be connected to the two adjacent side plates 4 respectively by fasteners.

[0079] Figure 5 In, there is an included angle between two adjacent side plates 4, and the splicing part between the two side plates 4 is arranged at the corner. Thus, the two adjacent second mounting protrusions 41 are arranged at an included angle at the splicing part, and one end of the third connecting member 5 can be arranged in a shape matching the included angle part for the positioning of the third connecting member 5.

[0080] Such as Figures 8 - 11 shown, the second connecting member 3 includes a first part 31 and a second part 32. The first part 31 covers the first mounting protrusion 11 and the second mounting protrusion 41. The second part 32 is connected to the side wall of the first part 31. The second part 32 covers and is connected to the side plate 4 and the base plate 1.

[0081] It can be understood that the first part 31 is higher than the second part 32. The first part 31 is used to connect two adjacent first mounting protrusions 11 (such as Figure 11 shown) or an adjacent first mounting protrusion 11 and a second mounting protrusion 41 (such as Figure 10 shown); the second part 32 is used to connect two adjacent base plates 1 or an adjacent base plate 1 and a side plate 4 to improve the connection strength. Optionally, the first part 31 includes an outer frame 311 and a bearing beam 312. The outer frame 311 covers the abutted first mounting protrusion 11 and the second mounting protrusion 41. The bearing beam 312 is arranged inside the outer frame 311 and covers the two abutted first mounting protrusions 11. It can be understood that the outer frame 311 is arranged in a ring shape and is used to connect the base plate 1 and the side plate 4 together; the bearing beam 312 is arranged at the middle position of the bottom plate and is used to connect the two base plates 1 together.

[0082] Optionally, there are two load-bearing beams 312, which are arranged in the middle of the outer frame 311, and there is a preset distance between the two load-bearing beams 312. It can be understood that the two load-bearing beams 312 respectively correspond to covering the joints of the two first mounting protrusions 11 of the fourth substrate 1 and the fifth substrate 1, and the second substrate 1 and the third substrate 1 mentioned above. It should be noted that Figure 5 In, one end in the width direction of the substrate 1 is provided with a first mounting protrusion 11, and the two sides in the length direction of the substrate 1 are not provided with first mounting protrusions 11. Therefore, on the two sides in the length direction of the substrate 1, the outer frame 311 only covers the second mounting protrusion 41, and the two sides of the outer frame 311 here can both be provided with second parts 32, and the two second parts 32 can be respectively connected to the side plate 4 and the substrate 1.

[0083] In addition, the load-bearing beam 312 can have threaded holes or through holes for wall mounting of the backboard. Optionally, the load-bearing beam 312 is provided with connecting protrusions, and the connecting protrusions extend in a direction away from the substrate 1. The connecting protrusion is provided with a threaded hole or a through hole coaxially arranged with the load-bearing beam 312 to increase the length of the connection between the fastener and the backboard.

[0084] Optionally, as Figure 12 shown, each of the two abutting first mounting protrusions 11 has a first threaded hole 71. When fixing the two abutting first mounting protrusions 11, the second connecting member 3 is covered on the two first mounting protrusions 11, and the two fasteners can respectively pass through the second connecting member 3 and be threadedly connected to the two first threaded holes 71;

[0085] Optionally, as Figure 12 shown, in the two abutting first mounting protrusions 11, each of the two first mounting protrusions 11 has a part of the same second threaded hole 72. Exemplarily, in the two abutting first mounting protrusions 11, one of the first mounting protrusions 11 has half of the second threaded hole 72, and the other first mounting protrusion 11 has half of the second threaded hole 72. The two half second threaded holes 72 can be opposite to form a complete second threaded hole 72. When fixing the two abutting first mounting protrusions 11, the second connecting member 3 is covered on the two first mounting protrusions 11, and the fastener can be threadedly connected to the complete second threaded hole 72 formed by the two opposite half second threaded holes 72. It should be noted that the abutting first mounting protrusion 11 and the second mounting protrusion 41 can also each have a part of the same second threaded hole 72.

[0086] Optionally, the outer frame 311 and the load-bearing beam 312 can be integrally provided to improve the strength of the second connecting member 3.
