[0039] like Figure 1As shown, an embodiment of this utility model provides a back wall support structure 1, including a base 11 and an upper frame 12. The base 11 includes a lower connecting plate 111 and a first connecting portion 113 disposed on both sides of the lower connecting plate 111 along a first direction. The lower connecting plate 111 is used to connect a tabletop 3. The first connecting portion 113 is located above the lower connecting plate 111, and the first direction is perpendicular to the vertical direction. The upper frame 12 includes an upper connecting plate 121 located above the lower connecting plate 111 and a second connecting portion 123 disposed on both sides of the upper connecting plate 121 along the first direction. The upper connecting plate 121 is used to connect a back wall body 2. The second connecting portion 123 is located below the upper connecting plate 121. The first connecting portion 113 and the second connecting portion 123 located on the same side of the base 11 in the first direction are connected.

[0040] The base 11 is connected to the upper frame 12 through the first connecting part 113 and the second connecting part 123. The lower connecting plate 111 can provide support for the upper connecting plate 121 through the first connecting part 113 and the second connecting part 123. The lower connecting plate 111 is connected to the table 3, and the upper connecting plate 121 is connected to the back wall body 2. The table 3 provides basic support for the lower connecting plate 111. The lower connecting plate 111 supports the upper connecting plate 121, and the upper connecting plate 121 provides support for the back wall body 2. This not only prevents the back wall from deforming due to insufficient support, improves the flatness of the back wall, and extends the service life of the back wall, but also connects the back wall body 2 and the back wall support structure 1 to form a whole, which can prevent the back wall from shifting or shaking during use, and greatly improves the stability of the back wall.

[0041] For example, the first connecting portion 113 and the second connecting portion 123 can be a welded integral structure.

[0042] Furthermore, the lower connecting plate 111 is provided with support plates 114 on both sides along the second direction, and the upper connecting plate 121 is provided with support grooves 124 corresponding to the support plates 114. The upper end of the support plate 114 is provided with a support protrusion, which passes through the support groove 124 and supports the lower surface of the upper connecting plate 121 by the support plate 114; the second direction is perpendicular to the first direction and the vertical direction.

[0043] For example, the opening direction of the support groove 124 is the second direction, the support protrusion of the support plate 114 abuts against the bottom wall of the support groove 124 along the second direction, and the upper connecting plate 121 is sandwiched between the two support plates 114 along the second direction. The support plate 114 can limit the upper connecting plate 121, effectively preventing the upper connecting plate 121 from moving along the second direction, and ensuring that the lower connecting plate 111 and the upper connecting plate 121 are always aligned.

[0044] like Figure 1As shown, the top of the support plate 114 is provided with clearance spaces on both sides along the second direction. The support protrusion protrudes vertically from the side wall of the clearance space and passes through the support groove 124. The bottom wall of the clearance space supports the lower surface of the upper connecting plate 121, which not only avoids interference between the support plate 114 and the upper connecting plate 121, but also provides support for the upper connecting plate 121. In turn, the upper connecting plate 121 provides support for the back wall body 2, improving the flatness and stability of the back wall.

[0045] In other embodiments, the upper connecting plate 121 has support plates 114 on both sides along the second direction, and the lower connecting plate 111 has support grooves 124 corresponding to the support plates 114. The lower end of the support plate 114 has a support protrusion that passes through the support groove 124 and is supported by the lower connecting plate 111. The lower connecting plate 111 supports the upper connecting plate 121 through the support plates 114, and the upper connecting plate 121 supports the back wall body 2, thereby improving the flatness and stability of the back wall.

[0046] Furthermore, the first connecting portion 113 is integrally formed on the lower connecting plate 111, the second connecting portion 123 is integrally formed on the upper connecting plate 121, and the support plate 114 is integrally formed on the upper connecting plate 121 or the lower connecting plate 111 connected thereto. This integral forming facilitates processing and saves costs. For example, the first connecting portion 113 is formed by bending the lower connecting plate 111 upwards, the second connecting portion 123 is formed by bending the upper connecting plate 121 downwards, and the support plate 114 is formed by bending the upper connecting plate 121 downwards at both ends in a second direction.

[0047] Furthermore, the first connecting portion 113 and the second connecting portion 123, located on the same side of the base 11 in the first direction, are connected by fasteners.

[0048] like Figure 1 As shown, the first connecting part 113 is provided with a first connecting hole, and the second connecting part 123 is provided with a second connecting hole. The base 11 and the upper frame 12 are fixed by fasteners passing through the first connecting hole and the second connecting hole. The base 11 is provided with a first connecting part 113 and a second connecting part 123 on both sides in the first direction, which can improve the overall connection stability of the back wall support structure 1.

[0049] Furthermore, the support plate 114 is connected to the lower connecting plate 111, and the top surface of the support protrusion is higher than the top surface of the upper connecting plate 121.

[0050] like Figure 1As shown, the top surface of the support plate 114 is higher than the top surface of the upper connecting plate 121, that is, the support protrusion of the support plate 114 can abut against the back wall body 2. The support plate 114 supports the back wall body 2, avoids the upper frame 12 from bearing the back wall body 2 under force, and prevents the fasteners passing through the first connecting hole and the second connecting hole from being damaged by shear force, which would affect the connection and fixation of the lower connecting plate 111 to the upper connecting plate 121.

[0051] In other embodiments, the support plate 114 is connected to the upper connecting plate 121, the bottom surface of the support protrusion is lower than the bottom surface of the lower connecting plate 111, the support protrusion can abut against the table board 3, and the support plate 114 supports the back wall body 2.

[0052] Furthermore, the first connecting parts 113 are all located on the side of the second connecting parts 123 closest to the other side of the second connecting parts 123, ensuring that all fasteners are installed from one side, making installation convenient. The second mounting hole adopts an elongated oval hole structure, with a certain amount of adjustment reserved, which can avoid interference or other abnormalities after the back wall is assembled due to processing or installation errors.

[0053] Furthermore, the lower connecting plate 111 is provided with a first mounting hole, which is used to connect the tabletop 3 with fasteners, thus serving to fix the overall foundation of the back wall support structure 1. Specifically, as shown... Figure 2 As shown, the tabletop 3 is provided with a first threaded hole 31, and a fastener is threaded into the first threaded hole 31 after passing through the first mounting hole.

[0054] Furthermore, the upper connecting plate 121 is provided with a second mounting hole, which is used to connect the back wall body 2 with fasteners, thereby supporting and fixing the back wall support structure 1 to the back wall body 2 as a whole. This prevents displacement under external force and avoids damage to the accessories on the back wall body 2. Specifically, such as... Figure 3 As shown, the bottom of the back wall body 2 is provided with a sliding groove 21, and a first nut is provided in the sliding groove 21. After the first nut is slid along the inner wall of the sliding groove 21 to a suitable position, it is then threaded onto the first nut by a fastener passing through the second connecting hole.

[0055] The fasteners mentioned in this embodiment are commonly used bolts, nuts, or screws.

[0056] During the installation of the back wall support structure, firstly, the lower connecting plate 111 is fixed to the table 3 by threading bolts through the first mounting holes on the lower connecting plate 111 and then threading them into the first threaded holes 31 on the table 3; secondly, the upper connecting plate 121 is fixed to the back wall body 2 by threading bolts through the second mounting holes on the upper connecting plate 121 and then threading them into the first nut at the bottom of the back wall body 2; finally, the base 11 and the upper frame 12 are connected and fixed by threading bolts through the first connecting holes on the first connecting part 113 and then threading them into the second connecting holes on the second connecting part 123.

[0057] Furthermore, the lower connecting plate 111 is provided with a first cable routing channel 112 extending vertically, and the upper connecting plate 121 is provided with a second cable routing channel 122 extending vertically. A third cable routing channel is formed between the base 11 and the upper frame 12, and the first cable routing channel 112 is connected to the second cable routing channel 122 through the third cable routing channel. The cable routing channels allow cables to pass through, thus concealing the cables and improving the overall neatness and aesthetics of the back wall.

[0058] Furthermore, the back wall support structure 1 also includes an outer shell, which has an installation channel running vertically through it. The first connecting part 113 and the second connecting part 123 are located within the installation channel, and the outer shell is sandwiched between the upper connecting plate 121 and the lower connecting plate 111 in a vertical direction.

[0059] After the first connecting part 113 and the second connecting part 123 are assembled, the outer shell is sandwiched between the upper connecting plate 121 and the lower connecting plate 111. The upper connecting plate 121 and the lower connecting plate 111 limit the outer shell to ensure that there is no significant shaking between the outer shell and the internal support structure. The outer shell is fitted on the outside of the first connecting part 113, the second connecting part 123 and the support plate 114, which can play a role in decoration and hiding cables, and improve the overall neatness and aesthetics of the back wall.

[0060] Furthermore, the outer casing includes a male outer casing connector 13 and a female outer casing connector 14. The inner wall of one of the male outer casing connector 13 and the female outer casing connector 14 is provided with a slot 141, and the inner wall of the other end is provided with a protrusion 131 corresponding to the slot 141. The protrusion 131 is engaged with the corresponding slot 141 and is located inside the corresponding slot 141. The male outer casing connector 13 and the female outer casing connector 14 form an installation channel. The connection position of the male outer casing connector 13 and the female outer casing connector 14 is located on opposite sides of the outer casing in the second direction, and is spaced apart from the support plate 114 in the second direction and arranged directly opposite each other.

[0061] When the outer casing needs to be disassembled according to actual needs, simply pinch the male connector 13 or female connector 14 with the locking protrusion 131. The male connector 13 or female connector 14 with the locking protrusion 131 will deform under external force and indent inward, causing the locking protrusion 131 to separate from the locking groove 141. Then, the male connector 13 and female connector 14 can be disassembled easily. The locking protrusion 131 is located inside the corresponding locking groove 141, which is more aesthetically pleasing.

[0062] For example, such as Figure 1 As shown, the male connector 13 of the outer shell has a locking protrusion 131, and the female connector 14 of the outer shell has a locking groove 141. The locking protrusion 131 and the locking groove 141 engage in a locking fit, making disassembly and assembly convenient. Inner grooves are provided on both sides of the lower connecting plate 111 in the second direction. One end of the support plate 114 is located within an inner groove. The inner groove provides deformation space for the outer shell, and the connection position of the male connector 13 and the female connector 14 of the outer shell is directly opposite the inner groove. In other embodiments, the male connector 13 of the outer shell may also have a locking groove 141, and the female connector 14 of the outer shell may have a locking protrusion 131, which engages in a locking fit with the locking groove 141.

[0063] In other embodiments, the connection positions of the male housing connector 13 and the female housing connector 14 are located on opposite sides of the housing in the first direction, and are spaced apart from and directly opposite the first connecting portion 113 along the first direction. Inner grooves are provided on both sides of the lower connecting plate 111 in the first direction, and the first connecting portion 113 is disposed in one of these inner grooves, with the connection positions of the male housing connector 13 and the female housing connector 14 directly opposite these inner grooves. In other embodiments, the first connecting portion 113 and the connection position are spaced apart along the second direction.

[0064] Furthermore, one end face of the male connector 13 and the female connector 14 of the outer casing has a protrusion, and the other end face has a groove. The protrusion and the groove engage with each other, which can play a positioning role during the assembly of the male connector 13 and the female connector 14 of the outer casing, making installation quick.

[0065] Specifically, the protrusion includes a first protrusion and a second protrusion, and the groove includes a first notch and a second notch. The end face of the male housing 13 facing the female housing 14 is provided with a first notch, which is arranged vertically and extends to the outer wall of the male housing 13, so that the male housing 13 forms a first protrusion. The end face of the female housing 14 facing the male housing 13 is provided with a second notch, which is arranged vertically and extends to the inner wall of the female housing 14, so that the female housing 14 forms a second protrusion. When the male housing 13 and the female housing 14 are assembled, the first protrusion is inserted into the second notch, and the second protrusion is inserted into the first notch.

[0066] Furthermore, the outer walls of the male connector 13 and the female connector 14 of the outer casing are flush, and there are no obvious gaps at the joint of the male connector 13 and the female connector 14 of the outer casing, making it more aesthetically pleasing.

[0067] Furthermore, the upper and lower edges of the male housing 13 are provided with inwardly folded flanges, and the upper and lower edges of the female housing 14 are also provided with inwardly folded flanges. The flanges on the upper edges of the male housing 13 and the female housing 14 abut against the lower surface of the upper connecting plate 121, and the flanges on the lower edges of the male housing 13 and the female housing 14 abut against the upper surface of the lower connecting plate 111. The flanges increase the contact area between the housing and the lower connecting plate 111 and the upper connecting plate 121, thereby improving the overall strength of the housing and making it less prone to deformation.

[0068] For example, the flanges on the upper and lower edges of the male housing 13 and the upper and lower edges of the female housing 14 are all set as inward flanges, which can improve the aesthetic effect of the housing.

[0069] like Figure 4 As shown, an embodiment of this utility model provides a back wall, including multiple back wall bodies 2, a table 3, and a back wall support structure 1. The multiple back wall bodies 2 are connected sequentially along a preset direction. The table 3 is located below the back wall bodies 2. Each back wall body 2 is equipped with at least one back wall support structure 1. The back wall support structure 1 is located vertically between the corresponding back wall body 2 and the table 3. An upper connecting plate 121 is connected to the back wall body 2, and a lower connecting plate 111 is connected to the table 3.

[0070] The tabletop 3 provides basic support for the back wall support structure 1, and the back wall support structure 1 provides support for the back wall main body 2, so that the back wall is subjected to uniform force and is not easily deformed, thereby improving the flatness and stability of the back wall and extending its service life.

[0071] By fixing the upper and lower ends of the back wall support structure 1 to the back wall body 2 and the table 3 respectively, the table 3 can not only provide basic support for the back wall support structure 1 and the back wall body 2, but also connect the back wall body 2 and the back wall support structure 1 to form a whole, which can prevent the back wall from shifting or shaking during use and improve the stability of the back wall.

[0072] Furthermore, the tabletop 3 is provided with a cable tray 32, which is connected to the first cable routing channel 112 on the lower connecting plate 111, providing cable routing space for internal electrical components such as the back wall acrylic light strip and flexible screen.

[0073] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
