[0031] Please refer to the following: Figures 1 to 3The first embodiment of this application provides a deformation-resistant plastic frame 10, including an iron frame 20 and a plastic frame 30. The iron frame 20 has a base plate 21 and side iron plates 22. The side iron plates 22 are disposed on the outer peripheral edge of the base plate 21. The side iron plates 22 have an outer peripheral surface 23 and a top surface 24 facing away from the base plate 21. A plurality of side locking blocks 25 are disposed on the outer peripheral surface 23, and a plurality of top locking blocks 26 are disposed on the top surface 24. The plastic frame 30 has a plastic frame body 31, and a top inner expansion plate 32 and an outer frame plate 33, both disposed on the plastic frame body 31. The frame is arranged in an L-shape. The top inner expansion plate 32 is provided with several top slots 34, and the outer frame plate 33 is provided with several outer peripheral slots 35. The side locking blocks 25 are engaged with the outer peripheral slots 35 one by one to limit the iron frame 20 and the plastic frame 30 in the vertical (thickness direction). The top locking blocks 26 are engaged with the top slots 34 one by one to limit the iron frame 20 and the plastic frame 30 in the horizontal (inward) direction (with the centroid of the iron frame 20 as the inside), thereby preventing the plastic frame 30 and the iron frame 20 from separating and deforming in the four directions of horizontal, vertical, and horizontal.

[0032] In some embodiments, several side locking blocks 25 and several top locking blocks 26 are arranged facing each other, and several top locking slots 34 and outer peripheral locking slots 35 are also arranged facing each other. That is to say, when the glue iron 10 is cut along the vertical direction, the four structures of top locking block 26, top locking slot 34, side locking block 25 and outer peripheral locking slot 35 can be cut at the same time. This can further enhance the limiting and anti-detachment effect of the four structures of top locking block 26, top locking slot 34, side locking block 25 and outer peripheral locking slot 35 on the glue frame 30 and iron frame 20 in four directions, and further enhance the anti-deformation capability of the anti-deformation glue iron 10.

[0033] In some embodiments, the side locking blocks 25 and the top locking blocks 26 are alternately arranged at intervals. At the same time, the top locking slots 34 and the outer peripheral locking slots 35 are also alternately arranged at intervals. That is to say, when cutting the glue frame 10 in the vertical direction, it is only possible to cut the top locking block 26 and the top locking slot 34, or the side locking block 25 and the outer peripheral locking slot 35 at the same time. There is no possibility of cutting the four structures of the top locking block 26, the top locking slot 34, the side locking block 25 and the outer peripheral locking slot 35 at the same time. Thus, after the four structures of the top locking block 26, the top locking slot 34, the side locking block 25 and the outer peripheral locking slot 35 are combined, the glue frame 30 and the iron frame 20 are limited and prevented from falling off in four directions. At the same time, the problem of local structural weakness caused by the groove in the same area of ​​the glue frame 30 is prevented.

[0034] Please refer to the following: Figure 4In some embodiments, each of the side locking blocks 25 has a first upper surface 251 facing the frame body 31. The first upper surface 251 is configured as an arc surface or a beveled surface, and the distance between it and the frame body 31 increases in the direction away from the side iron plate 22. This can prevent the side locking blocks 25 from colliding with the outer peripheral locking groove 35 near the groove wall of the frame body 31 when assembling the iron frame 20 and the frame 30, thus preventing damage to the iron frame 10 structure.

[0035] Please refer to the following: Figure 5 and Figure 6 In some embodiments, each of the top locking blocks 26 has four edges, and the edges are all set as rounded edges or beveled edges 261; thereby preventing the top locking blocks 26 from colliding with the groove wall of the top locking groove 34 when assembling the iron frame 20 and the plastic frame 30, thus preventing damage to the plastic iron 10 structure.

[0036] Please refer to the reference again. Figure 4 In some embodiments, a plurality of peripheral slots 35 are provided with peripheral slot openings 351 for engaging the side block 25. The peripheral slot openings 351 are all flared guide structures, which further facilitates the engagement of the side block 25 into the peripheral slot 35 and further prevents the side block 25 from colliding with the groove wall of the peripheral slot 35 near the glue frame body 31 when assembling the iron frame 20 and the glue frame 30, thus preventing damage to the glue frame 10 structure.

[0037] Please refer to the reference again. Figure 6 In some embodiments, several top slots 34 are provided with top slot openings 341 for engaging the top block 26, and several top slot openings 341 are flared guide structures; thereby further facilitating the engagement of the top block 26 into the top slot 34, and further preventing the top block 26 from colliding with the groove wall of the top slot 34 during the assembly of the iron frame 20 and the plastic frame 30, which would cause damage to the plastic frame 10 structure.

[0038] The second embodiment of this application also provides a backlight source, which includes the anti-deformation plastic iron as provided in the first embodiment of this application, thereby effectively avoiding light leakage or poor display problems caused by deformation of the plastic iron. See the first embodiment of this application for details.

[0039] The third embodiment of this application also provides a display device, which includes a backlight source as provided in the second embodiment of this application, thereby effectively avoiding problems such as light leakage or poor display in the display device.

[0040] The fourth embodiment of this application also provides a smart mobile terminal, which includes a backlight as provided in the second embodiment of this application, thereby effectively avoiding problems such as light leakage or poor display of the display device.

[0041] In summary, this application provides an anti-deformation plastic frame, a backlight, a display device, and a smart mobile terminal. The anti-deformation plastic frame includes: an iron frame having a base plate and side iron plates, the side iron plates being disposed at the outer peripheral edge of the base plate, the side iron plates having an outer peripheral surface and a top surface facing away from the base plate, the outer peripheral surface having a plurality of side locking blocks, and the top surface having a plurality of top locking blocks; and a plastic frame having a plastic frame body, and a top inner expansion plate and an outer frame plate both disposed on the plastic frame body, the top inner expansion plate having an L-shaped structure, the top inner expansion plate having a plurality of top locking slots, and the outer frame plate having a plurality of outer peripheral locking slots; wherein, the plurality of side locking blocks and the plurality of outer peripheral locking slots are engaged one-to-one to limit the vertical movement of the iron frame and the plastic frame; the plurality of top locking blocks and the plurality of top locking slots are engaged one-to-one to limit the internal and external movement of the iron frame and the plastic frame. The square variable-resin frame is equipped with several side locking blocks on its outer peripheral surface, several top locking blocks on its top surface, several top locking slots on its inner top expansion plate, and several outer peripheral locking slots on its outer frame plate. This allows the side locking blocks to engage with the outer peripheral locking slots in a one-to-one correspondence, limiting the vertical movement of the iron frame and the plastic frame. Similarly, the top locking blocks and top locking slots engage with each other in a one-to-one correspondence, limiting the internal and external movement of the iron frame and the plastic frame, thus preventing them from separating or deforming in all four directions (up, down, and external).
