[0023] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0024] An assembly structure of the upper and lower iron frames of a display module, referring to Figure 1 , includes a display screen 10 and a backlight 20, and the display screen 10 is accommodated in the backlight 20. The backlight 20 is provided with an upper iron frame 21 and a lower iron frame 22, and the upper iron frame 21 and the lower iron frame 22 are assembled and fixed. The upper iron frame 21 is provided with a hollow, and the side of the lower iron frame 22 facing the upper iron frame 21 is provided with an opening, and the display screen 10 is accommodated in the lower iron frame 22. The upper iron frame 21 is buckled to the periphery of the lower iron frame 22, and a screw fixing structure for assembling and fixing is provided between the upper iron frame 21 and the lower iron frame 22.

[0025] Referring to Figure 1 , since the upper iron frame 21 and the lower iron frame 22 in the prior art are buckled and fixed by a buckle, and the buckle needs to reserve a certain safety gap, which causes a certain looseness in the buckling of the upper iron frame 21 and the lower iron frame 22. Therefore, in this embodiment, a screw fixing structure is provided, and the upper iron frame 21 and the lower iron frame 22 are fixed by screws, ensuring the assembly stability of the upper iron frame 21 and the lower iron frame 22.

[0026] Referring to Figure 2 and Figure 3 , the screw fixing structure is arranged between the periphery of the upper iron frame 21 and the periphery of the lower iron frame 22. The screw fixing structure includes a circular hole 211 opened on the periphery of the upper iron frame 21, a screw hole 221 opened on the periphery of the lower iron frame 22, and an anti-slip screw 30 passing through between the circular hole 211 and the screw hole 221. The circular hole 211 is circularly opened on the periphery of the upper iron frame 21, the screw hole 221 is opened at a position corresponding to the circular hole 211, and the screw hole 221 and the circular hole 211 are arranged oppositely. The inner wall of the screw hole 221 is provided with a thread for threadedly connecting with the anti-slip screw 30. Among them, the size of the circular hole 211 is slightly larger than the size of the screw hole 221 for the anti-slip screw 30 to pass through. The anti-slip screw 30 sequentially passes through the circular hole 211 and the screw hole 221 from the outside of the upper iron frame 21 and is threadedly connected with the thread on the inner wall of the screw hole 221 to achieve locking.

[0027] Furthermore, referring to Figure 2 and Figure 3 , the aperture of the circular hole 211 is 1.8 mm, and the aperture of the screw hole 221 is 1.6 mm.

[0028] Further, referring to Figure 4 and Figure 5 , the backlight 20 further includes a rubber holder 23. The rubber holder 23 is assembled and fixed to the lower iron holder 22. The rubber holder 23 is hollow and is located inside the lower iron holder 22. The rubber holder 23 is used to limit the display screen 10 to prevent the display screen 10 from shifting within the backlight 20. An avoidance groove 231 is formed at the position of the rubber holder 23 relative to the screw hole 221. The avoidance groove 231 is used to allow the anti-slip screw 30 to pass through the circular hole 211 and the screw hole 221 and then be locked into the rubber holder 23 for fixation.

[0029] Referring to Figure 4 and Figure 5 , in this embodiment, there are multiple screw fixing structures. The multiple screw fixing structures are arranged along the circumferential direction of the outer periphery of the upper iron holder 21 and the lower iron holder 22. The number of screw fixing structures can be determined according to the size of the display module to ensure the connection stability between the upper iron holder 21 and the lower iron holder 22.

[0030] Further, referring to Figure 4 and Figure 5 , a washer 40 is sleeved on the anti-slip screw 30. The washer 40 is made of rubber material. One side of the washer 40 abuts against the anti-slip screw 30, and the other side of the washer 40 abuts against the outer periphery of the upper iron holder 21. The washer 40 is used to play a buffering role when the anti-slip screw 30 is locked with the upper iron holder 21, and can limit the anti-slip screw 30 so that the anti-slip screw 30 can be locked between the upper iron holder 21 and the lower iron holder 22.

[0031] Further, referring to Figure 4 and Figure 5 , the number of washers 40 can be set to one or more according to actual needs.

[0032] Referring to Figure 4 and Figure 5 , this assembly structure sets screw fixing structures to replace the assembly method of the buckles of the upper iron holder 21 and the lower iron holder 22. By sequentially passing the anti-slip screw 30 through the circular hole 211 of the upper iron holder 21 and the screw hole 221 of the lower iron holder 22 and locking it into the rubber holder 23 of the backlight 20, the upper iron holder 21 and the lower iron holder 22 are fixed, thereby ensuring the assembly stability of the upper iron holder 21 and the lower iron holder 22.

[0033] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
