[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0025] This application provides a front frame assembly, a backlight module, and a display device, which improve structural reliability and aesthetic appearance. The following description, in conjunction with the accompanying drawings, provides a detailed explanation.

[0026] Please see Figure 1 as well as Figure 2 , Figure 1 This is a schematic diagram of the structure of the front frame assembly provided in an embodiment of this application. Figure 2 for Figure 1 An enlarged schematic diagram of part A. This application provides a front frame assembly 100, which includes a first front frame member 10, a second front frame member 20, and a corner connector 30. The first front frame member 10 has a first receiving cavity 11, and a first limiting groove is provided on the cavity wall of the first receiving cavity 11.

[0027] Please see Figure 3 , Figure 3 This is a schematic diagram of a first structure of the corner connector provided in an embodiment of this application. The corner connector 30 includes a corner portion 31, a first cantilever 32, and a second cantilever 33. The first cantilever 32 and the second cantilever 33 are respectively connected to the corner portion 31. The first cantilever 32 is connected to the first front frame 10, and the second cantilever 33 is connected to the second front frame 20. The first cantilever 32 is disposed in the first receiving cavity 11, and a first limiting protrusion 321 is provided on the first cantilever 32. The first limiting protrusion 321 is engaged in the first limiting groove.

[0028] The first front frame 10 and the second front frame 20 extend in different directions. For example, the first front frame 10 extends along a first direction, while the second front frame 20 extends along a second direction. The first direction is perpendicular to the second direction.

[0029] The depth direction of the first receiving cavity 11 on the first front frame 10 is the same as the extension direction of the first front frame 10.

[0030] The first cantilever 32 and the second cantilever 33 extend in different directions. For example, the first cantilever 32 extends along a first direction, and the second cantilever 33 extends along a second direction. The first cantilever 32 can be disposed in the first receiving cavity 11 along the first direction, and the second cantilever 33 can be connected to the second front frame 20. For example, the second cantilever 33 can also be disposed in the second receiving cavity 21 of the second front frame 20 along the second direction. The first cantilever 32 and the second cantilever 33 can fix the relative positions of the first front frame 10 and the second front frame 20.

[0031] The first limiting groove on the cavity wall of the first receiving cavity 11 communicates with the first receiving cavity 11. The first limiting protrusion 321 on the first cantilever 32 is arranged along the length direction of the first cantilever 32, and the shape of the first limiting protrusion 321 corresponds to the shape of the first limiting groove. When the first cantilever 32 is placed in the first receiving cavity 11, the first limiting groove can engage with the first limiting protrusion 321 on the first cantilever 32 to prevent the first front frame 10 from rotating around its own length direction and causing it to flip inward or outward, thereby improving the reliability of the structure.

[0032] The first limiting protrusion 321 is a rib, which not only serves as a limiting element but also strengthens the structure of the first cantilever 32.

[0033] After the first front frame 10 and the second front frame 20 are connected to the corner connector 30, the corner part 31 is located between the first front frame 10 and the second front frame 20, which can fill the gap between the first front frame 10 and the second front frame 20 and improve the aesthetics.

[0034] The distance between the first cantilever 32 and the cavity wall of the first receiving cavity 11 is 0.1mm to 0.5mm, for example, 0.25mm. This will prevent the gap between the first cantilever 32 and the first receiving cavity 11 from being too large when the first cantilever 32 is inserted into the first receiving cavity 11, thus preventing loosening.

[0035] In one case, please refer to Figure 4 as well as Figure 5 , Figure 4 This is a schematic diagram of a second structure of the corner connector provided in an embodiment of this application. Figure 5 for Figure 1A magnified schematic diagram of part B. The front frame assembly 100 also includes a third cantilever 34, which is connected to the corner portion 31, parallel to the second cantilever 33, and connected to the second front frame member 20. It can be understood that the second cantilever 33 and the third cantilever 34 together connect to the second front frame member 20, serving a reinforcing function. Simultaneously, since both the second cantilever 33 and the third cantilever 34 can restrain the second front frame member 20, they strengthen the overall structure of the second front frame member 20, preventing it from folding inward or outward and creating step differences, thus improving structural reliability.

[0036] In another case, please refer to [link / reference needed]. Figure 2 The second front frame 20 has a second receiving cavity 21, and a second cantilever 33 is disposed within the second receiving cavity 21. A second limiting groove is provided on the cavity wall of the second receiving cavity 21, and a second limiting protrusion 331 is provided on the second cantilever 33. The second limiting protrusion 331 engages with the second limiting groove. The second limiting groove on the cavity wall of the second receiving cavity 21 communicates with the second receiving cavity 21. The second limiting protrusion 331 on the second cantilever 33 is arranged along the length direction of the second cantilever 33, and the shape of the second limiting protrusion 331 corresponds to the shape of the second limiting groove. When the second cantilever 33 is disposed within the second receiving cavity 21, the second limiting groove can engage with the second limiting protrusion 331 on the second cantilever 33, thereby preventing the second front frame 20 from rotating inward or outward around its own length direction and improving the reliability of the structure.

[0037] The second limiting protrusion 331 is a rib, which not only serves as a limiting element but also strengthens the structure of the second cantilever 33.

[0038] Please continue reading. Figure 3 The corner connector 30 also includes a boss 35, which connects to the corner portion 31. The direction in which the boss 35 protrudes from the corner portion 31 is perpendicular to the plane containing the first front frame member 10, the second front frame member 20, and the corner portion 31. When the back panel 200 is fixed to the front frame assembly 100, the boss 35 is located between the back panel 200, the first front frame member 10, and the second front frame member 20, effectively blocking the internal structure and preventing issues such as poor sealing, light leakage, and / or poor appearance. The boss 35 can be fixed to the corner portion 31 along a third direction, so that after the front frame assembly 100 and the back panel are assembled, the boss 35 corresponds to the corner of the back panel 200, and the side of the boss 35 closest to the back panel corresponds to the side shape of the back panel to fill gaps and improve sealing. The first direction, the second direction, and the third direction are perpendicular to each other.

[0039] Please see Figure 6 , Figure 6This is a schematic diagram of a first structure of a backlight module provided in an embodiment of this application. This application also provides a backlight module 1, which includes a front frame assembly 100 and a back panel 200. The front frame assembly 100 is the same as the one described in the previous embodiment. The back panel 200 is connected to a first front frame member 10, a second front frame member 20, and a corner connector 30, respectively, to be fixed to the front frame assembly 100. The front frame assembly 100 surrounds the periphery of the back panel 200, and the front frame assembly 100 and the back panel 200 together form a receiving space to accommodate optical components.

[0040] Please see Figure 7 as well as Figure 8 , Figure 7 This is a schematic diagram of a second structure of the backlight module provided in an embodiment of this application. Figure 8 for Figure 7 An enlarged schematic diagram of part C is shown. This application also provides a backlight module 1, which includes a first front frame 10, a second front frame 20, a corner connector 30, and a back plate 200. The corner connector 30 includes a corner portion 31, a boss 35, a first cantilever 32, and a second cantilever 33. The first cantilever 32 and the second cantilever 33 are respectively disposed on both sides of the corner portion 31. The first front frame 10 is connected to the first cantilever 32, and the second front frame 20 is connected to the second cantilever 33. The boss 35 protrudes from the corner portion 31. The back plate 200 overlaps the corner portion 31, and the boss 35, the first front frame 10, and the second front frame 20 surround the periphery of the back plate 200.

[0041] The boss 35 is located between the back plate 200, the first front frame 10, and the second front frame 20, and can block the internal structure of the backlight module 1 to avoid problems such as poor sealing, light leakage, and / or poor appearance. The boss 35 can be fixed to the corner 31 along a third direction, so that after the front frame assembly 100 and the back plate 200 are assembled, the boss 35 corresponds to the corner of the back plate 200, and the side of the boss 35 near the back plate 200 corresponds to the side shape of the back plate 200 to fill the gap and improve the sealing. The first direction, the second direction, and the third direction are perpendicular to each other.

[0042] This application provides a display device including a backlight module 1 and a liquid crystal module, wherein the light generated by the backlight module 1 is used to illuminate the liquid crystal module.

The first cantilever 32 and the second cantilever 33 of the corner connector 30 can fix the relative positions of the first front frame member 10 and the second front frame member 20. The limiting rib on the first cantilever 32 can prevent the first front frame member 10 from rotating, thereby preventing the first front frame member 10 from flipping and causing a step difference, which is beneficial to improving the reliability of the structure. After the first front frame member 10 and the second front frame member 20 are respectively connected to the corner connector 30, the corner portion 31 is disposed between the first front frame member 10 and the second front frame member 20, which can fill the gap between the first front frame member 10 and the second front frame member 20, which is beneficial to improving the aesthetics.
