[0020] like Figure 1 As shown, the support structure of the flat-panel TV disclosed in the utility model comprises a back panel module 100, a diffuser 200, a membrane 300 and a support base 400. The back panel module 100 is an L-shaped structure consisting of a back panel body 110 and a side 120 fixed to the back panel body 110; the diffuser 200 is installed between the back panel body 110 and the membrane 300; the membrane 300 is assembled by providing a hanging ear and a hanging ear opening 310 on the hanging ear.

[0021] The utility model realizes the positioning of the diffuser plate 200 and the assembly of the diaphragm 300 by adding a support base 400; Figure 3As shown, the support base 400 is composed of a connecting portion 410, a first step portion 420 and a second step portion 430. The connecting portion 410 is a portion where the support base 400 is directly connected to the back plate body 110. The connecting portion 410 adopts a plate structure with a certain thickness, and the connecting portion 410 can be fixed to the back plate body 110 in a detachable connection manner. The first step portion 420 and the second step portion 430 are plate structures with different lengths. The first step portion 420 and the second step portion 430 are both vertically arranged. The first step portion 420 is fixed on the connecting portion 410, and the second step portion 430 is fixed on the first step portion 420. The length of the first step portion 420 is greater than the length of the second step portion 430 so that the support base 400 presents a stepped shape.

[0022] like Figure 1 and Figure 2 As shown, the support base 400 used in the present invention is provided with a first step portion 420 as a positioning component of the diffuser plate 200, and a second step portion 430 as an assembly component of the diaphragm 300. The first step portion 420 cooperates with the diffuser plate 200 in a limiting matching manner, and a positioning notch 210 is provided at the edge of the diffuser plate 200 close to the side edge 120. The length of the positioning notch 210 is adapted to the length of the first step portion 420 so that the first step portion 420 can be just inserted into the positioning notch 210. The edge of the diffuser plate 200 abuts against the side edge 120 of the back plate module 100, and the three inner walls of the positioning notch 210 abut against the two side surfaces of the first step portion 420 and a surface away from the side edge 120, thereby forming four different position limits for the diffuser plate 200, and accurately positioning the diffuser plate 200 during assembly. The second step portion 430 also realizes the installation of the diaphragm 300 by limiting the fit; a protruding ear is provided on the edge of the diaphragm 300, and the middle part of the ear is an ear opening 310. The size of the ear opening 310 is slightly larger than the cross-sectional size of the second step portion 430 and slightly smaller than the cross-sectional size of the first step portion 420. The second step portion 430 can be inserted into the ear opening 310, so that the diaphragm 300 is hung on the second step portion 430 of the bracket base 400, and the diaphragm 300 can be placed on the top surface of the first step portion 420 to form support for the diaphragm 300 and position it in a direction perpendicular to the diaphragm 300. The utility model realizes positioning of the diffuser plate 200 and assembly of the diaphragm 300 at the same time by setting a stepped bracket base 400, thereby effectively reducing the difficulty of assembly and improving the assembly accuracy and efficiency; and there is no need to process holes on the back panel module 100, thereby effectively ensuring the integrity and strength of the structure of the back panel module 100. At the same time, the bracket base 400 can support the diaphragm 300 and the side 120 to reinforce the assembly position, effectively solving the problem of poor stress conditions at the assembly position, thereby further improving the strength.

[0023] like Figure 3 and Figure 4 As shown, the detachable connection between the support base 400 and the back panel module 100 in the present invention is achieved by the threaded connection of the screw 500. A connecting through hole 440 is provided on the connecting portion 410 of the support base 400 and penetrates the connecting portion 410 longitudinally. At the same time, a connecting hole 111 which is connected to the connecting through hole 440 is provided at a corresponding position of the back panel body 110. The connecting hole 111 is an internal threaded hole. After the screw 500 penetrates the connecting through hole 440 on the connecting portion 410 and then is threadedly connected to the connecting hole 111 on the back panel body 110, the connection and fixation of the support base 400 and the back panel module 100 can be completed. In order to ensure the accuracy of the positioning of the bracket base 400, a positioning structure composed of a limiting hole 112 and a limiting protrusion 450 is also provided in the utility model; a protruding limiting protrusion 450 is fixed at the bottom of the connecting portion 410, and a limiting hole 112 matched with the limiting protrusion 450 is provided at a corresponding position on the back plate body 110. The shape of the limiting protrusion 450 is not limited, and a rectangular column and other angular structures are used as the preferred solution, because the rectangular column can achieve circumferential limitation and the positioning effect is better; during assembly, the limiting protrusion 450 can be first inserted into the limiting hole 112 to achieve positioning and then the screw 500 can be connected.

[0024] Furthermore, a sinking portion 113 adapted to the connecting portion 410 may be provided on the back plate body 110, and the sinking portion 113 is formed by partially sinking the connecting portion 410 to a certain height, and the connecting hole 111 and the limiting hole 112 are both provided on the sinking portion 113. The sinking height of the sinking portion 113 is equal to the thickness of the connecting portion 410, so that the connecting portion 410 can be flush with other parts of the back plate body 110 after being installed at the sinking portion 113 of the back plate body 110, thereby improving the utilization of space while ensuring the levelness and stability of the diffuser 200.

[0025] In order to provide installation space for the screw 500 and ensure that the diffuser plate 200 located above the screw 500 remains flat after assembly, the utility model provides an avoidance step 460 on the connecting portion 410 as the installation position of the screw 500. Figure 3 and Figure 4As shown, a portion of the connecting portion 410 connected to the first step portion 420 is sunken to form an avoidance step 460, the first step portion 420 is fixed on the non-sunk portion of the connecting portion 410 and the two sides of the first step portion 420 are flush with the two sides of the non-sunk portion of the connecting portion 410; the positioning notch 210 of the diffuser plate 200 is in contact with the two sides of the first step portion 420 and the two sides of the non-sunk portion of the connecting portion 410; the connecting hole 111 is provided on the avoidance step 460. The sinking height of the avoidance step 460 should be equal to the thickness of the pan head of the screw 500 to prevent the top of the diffuser plate 200 from being deflected due to the excessive thickness of the pan head of the screw 500.
