It should be noted that, in the prior art, a screw hole is generally reserved on a positioning convex hull of a back plate, when a main board of a display device (for example, a television) is assembled, a mounting hole on the main board needs to be aligned with a corresponding screw hole on the back plate, then a special screw is prepared, if an electric screw driver is used, a standard torsion needs to be adjusted, and then the screw is locked into the screw hole of the corresponding convex hull.

The embodiment of the application provides a backboard assembly, which has a simple structure and can improve the assembly efficiency of a backboard and a main board, and the backboard assembly and the main board are respectively described in detail below.

Referring to fig. 1 to 5, a back plate 100 assembly according to an embodiment of the present application includes a back plate 100 and a plurality of convex hulls 200. It should be noted that the number of the convex hulls 200 may be one, two or more, and the number of the convex hulls 200 is 4 by way of example, and the specific number of the convex hulls 200 may be set according to need, which is not limited herein. The structure of the back plate 100 is not a major improvement of the present application, and is not limited herein. Specifically, the back plate 100 and the convex hull 200 may be an integral structure, and the convex hull 200 is integrally formed on the back plate 100 by using a stamping process, which is beneficial to increase the connection strength between the back plate 100 and the convex hull 200. Of course, in other embodiments of the present application, the convex hull 200 may be prepared separately, and then the convex hull 200 may be fixed (e.g., welded or screwed) to the back plate 100.

Referring to fig. 4 and 5, the convex hull 200 includes a body 210, a connecting portion 220, and an elastic portion 230 sequentially disposed along a length direction thereof, the elastic portion 230 and the body 210 are fixedly connected through the connecting portion 220, one end of the body 210 away from the connecting portion 220 is fixedly connected with the back plate 100, a limit groove 240 is disposed between the elastic portion 230 and the body 210, and the limit groove 240 is used for accommodating the main plate 300; the elastic portion 230 and the main body 210 are respectively in abutment and limit with the main board located in the limit groove 240, that is, one surface of the main board 300 facing the elastic portion 230 is in abutment and limit with the elastic portion 230, and one surface of the main board 300 facing the main body 210 is in abutment and limit with the main body 210.

Wherein the elastic part 230 has an initial state (as shown in fig. 3 to 5) and an elastic state (not shown) deformed by being pressed by an external force; the elastic portion 230 is configured to pass through the mounting hole in the elastic state, and to abut against and limit with a surface of the main board, which faces away from the convex hull 200, in the initial state. Illustratively, the back plate 100 is a planar plate structure, and the convex hulls 200 are disposed on the same side of the back plate 100, and each convex hull 200 extends in a direction substantially perpendicular to the back plate 100. The initial state of the elastic portion 230 refers to an initial state in which the elastic portion is not deformed by an external force, that is, a state other than the elastic state. The shape and material of the elastic portion 230 are not particularly limited in the present application, and the elastic portion 230 only needs to be elastically deformed (the volume becomes smaller) through the mounting hole on the main board under the action of external force extrusion, and can be restored to the initial state (the volume becomes larger) after the external force is removed, so that the elastic portion 230 can be abutted against one surface of the main board facing away from the body 210 of the convex hull 200, for example, the elastic portion 230 can be made of a metal material, a rubber material, or a fiber composite material. The appearance of the elastic portion 230 may be an elastic boss, an elastic ball, an elastic cone, an elastic sheet, or the like.

It can be appreciated that, according to the present application, the elastic portion 230 is controlled to elastically deform under the extrusion action of the external force so as to pass through the mounting hole, and the elastic portion 230 is restored to the initial state to be in abutment with and limit with the side of the main board facing away from the convex hull 200, and the main board 300 can be fixedly mounted in the limiting groove 240 by abutment and limit between the main body 210 of the convex hull and the side of the main board 300 facing away from the elastic portion 230. Compared with the prior art, the assembly of the main board 300 can be realized only by enabling the elastic part 230 to pass through the mounting hole under the action of external force, and screws and screwdrivers are not needed in the assembly process of the main board 300 and the back board 100, so that the assembly efficiency of the back board 100 and the main board 300 is improved.

In some embodiments of the present application, the elastic portion 230 has an inverted conical structure, and the cross-sectional area of the cross-section of the elastic portion 230 (i.e., the cross-section perpendicular to the length direction of the convex hull) gradually decreases along the direction away from the back plate 100. This configuration allows the elastic portion 230 to pass through a mounting hole (not shown) in the main board 300 more conveniently. To facilitate understanding, an end of the elastic portion 230 away from the back plate 100 is defined as an insertion end of the elastic portion 230, an end of the elastic portion 230 near the back plate 100 is defined as an abutting end of the elastic portion 230, that is, a size of the insertion end of the elastic portion 230 is minimum, a size of the abutting end of the elastic portion 230 is maximum, and illustratively, a size of the insertion end of the elastic portion 230 is smaller than a size of the mounting hole, and a size of the abutting end of the elastic portion 230 is larger than the size of the mounting hole. When the main board 300 is assembled, the insertion end of the elastic portion 230 is first aligned with the mounting hole of the main board 300, and then the back board 100 and the main board 300 are driven to move in a direction approaching each other, the insertion end of the elastic portion 230 passes through the mounting hole, and since the abutting end of the elastic portion 230 has a size larger than the size of the mounting hole, the elastic portion 230 is pressed by the wall surface of the mounting hole during the process of passing the elastic portion 230 through the mounting hole, and the elastic portion 230 is elastically deformed under the pressing action to reduce the cross-sectional area of the elastic portion 230, so that the elastic portion 230 can smoothly pass through the mounting hole. After the abutting end of the elastic portion 230 passes through the mounting hole, the elastic portion 230 is separated from the extrusion of the wall surface of the mounting hole, so as to restore to the initial state, and since the size of the elastic portion 230 in the initial state is larger than the size of the mounting hole, the elastic portion 230 and the surface of the main board 300 facing away from the convex hull 200 body 210 can be abutted and limited.

Further, the abutting end of the elastic portion 230 is adapted to the structure of the main board 300. Specifically, the abutting end of the elastic portion 230 has a planar structure, and the main board 300 has a planar structure, so that the abutting end of the elastic portion 230 has a larger contact area with the main board 300 when abutted against the main board 300, which is beneficial to increasing the acting force between the elastic portion 230 and the main board 300.

In some embodiments of the present application, referring to fig. 5, the body 210, the connecting portion 220, and the elastic portion 230 are all made of metal materials, the elastic portion 230 is provided with a through hole 270, and the through hole 270 penetrates through an end of the elastic portion 230 near the connecting portion 220 (i.e., a supporting end of the elastic portion 230) and extends to an end of the connecting portion 220 near the body 210. Specifically, the body 210 of the convex hull 200 is generally in a inverted "bowl" structure, the connecting portion 220 is generally in a cylindrical structure, the convex hull 200 is in an inverted cone structure, and the back plate 100, the body 210, the connecting portion 220 and the elastic portion 230 are metal members in an integral structure, which is beneficial to increasing the strength of the convex hull 200 and the connection strength between the back plate 100 and the convex hull 200. Meanwhile, in this embodiment, since the through hole 270 is formed in the elastic portion 230, the through hole 270 penetrates through an end of the elastic portion 230 near the connecting portion 220 and extends to an end of the connecting portion 220 near the body 210, so that the elastic portion 230 and the connecting portion 220 shrink inwards under the action of external force extrusion to enable the elastic portion 230 to enter into and exit from the mounting hole, and further improving the assembly and disassembly efficiency of the back plate 100 and the motherboard 300.

Of course, in other embodiments of the present application, the back plate 100 may be a metal plate or a fiber composite plate, the convex hull 200 is an integrally formed rubber structural member, and the convex hull 200 is fixed on the back plate 100, where the convex hull 200 may be fixed on the back plate 100 by an adhesive layer, or may be fixed on the back plate 100 by a threaded fastener, which is not limited herein.

In some embodiments of the present application, the cross-sectional shape of the connection portion 220 is adapted to the shape of the mounting hole. Specifically, the cross-sectional shape of the connection portion 220 is circular, the mounting hole is a circular hole, and the size of the connection portion 220 is similar to that of the mounting hole, and this structure is beneficial to further improving the connection stability between the motherboard and the back plate 100. Of course, in other embodiments of the present application, the cross-sectional shape of the connecting portion 220 may be triangular, square, polygonal, etc., which is not limited herein.

In some embodiments of the present application, referring to fig. 1, 3 to 5, the back plate assembly further includes an elastic member 280, where the elastic member 280 is sleeved on the connecting portion 220, that is, the elastic member 280 is located in the limiting slot 240 (for example, the elastic member 280 is located at an end of the limiting slot 240 near the body 210); when the main board 300 is located in the limiting groove 240, one end of the elastic member 280, which is close to the body 210, abuts against the body 210, and the other end of the elastic member 280 (i.e., the end facing away from the body 210) abuts against one surface of the main board 300 facing away from the elastic portion 230. Illustratively, the elastic member 280 may be a compression spring or an elastic block (e.g., a rubber block). In this implementation, the elastic piece 280 is disposed in the backboard assembly, and the body 210 of the convex hull 200 is abutted and limited with the main board 300 through the elastic piece 280, so that the backboard assembly in the application can be adapted to the main boards 300 with different thicknesses. Of course, in other embodiments of the present application, the back plate assembly may not be provided with the elastic member 280, and the body 210 of the convex hull 200 directly abuts against the main board 300, which is not limited herein.

In this embodiment, the elastic member 280 abuts against the main board 300 through the first spacer 250, so as to increase the contact area between the elastic member 280 and the main board 300, which is beneficial to improving the connection stability between the elastic member 280 and the main board.

Further, the first spacer 250 may be a metal spacer, the elastic member 280 is a metal spring, and the main board 300 is a metal plate (e.g. copper-clad plate). It can be appreciated that, due to the copper leakage at the mounting hole of the motherboard 300, and the first pad 250 and the elastic member 280 are electrically connected with the copper leakage of the motherboard 300, the motherboard and the back plate can share the same grounding signal, so that the stability and reliability of the circuit are improved.

In some embodiments of the present application, the back plate assembly further includes a second spacer 260, the second spacer 260 is sleeved on the connection portion 220, and the second spacer 260 is disposed between the elastic member 280 and the body 210.
