[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0019] Please refer to Figure 2 The embodiment of the present utility model provides a buckling structure of a backlight plastic frame and a metal frame, including a metal frame 1 and a backlight plastic frame 2. The following is a detailed description of the various components of this embodiment in conjunction with the accompanying drawings.

[0020] like Figure 2 and Figure 3 As shown, in this embodiment, the metal frame 1 can be covered on the two outer sides of the backlight plastic frame 2, and the outer edges of the two end portions on both sides of the metal frame 1 that are in contact with the outer walls of the backlight plastic frame 2 are respectively provided with opening grooves 11 inward.

[0021] like Figure 4 As shown, the surface of the backlight plastic frame 2 may be recessed at one side edge corresponding to each opening groove 11 to form a relief groove 21 , and a rib 3 is provided at one side edge of the opening groove 11 close to the corresponding relief groove 21 .

[0022] like Figure 5 As described above, in a specific implementation, the ribs 3 can be engaged with the corresponding avoidance grooves 21 by bending inwards, thereby achieving mutual engagement between the metal frame 1 and the backlight plastic frame 2 .

[0023] Among them, the metal frame 1 can be used to support and fix the backlight source plastic frame 2, providing structural strength and stability for the backlight source plastic frame 2, and also helping to dissipate heat, thereby extending the service life of the backlight source. The backlight source plastic frame 2 is used to fix the backlight source and combine it with other components of the display.

[0024] Furthermore, when the metal frame 1 is covered on the backlight plastic frame 2, the two inner walls of the metal frame 1 are in contact with the two outer walls of the backlight plastic frame 2. A recessed avoidance groove 21 is provided on the backlight plastic frame 2 to cooperate with the open groove 11 on the metal frame 1. The rib 3 is located on one side of the avoidance groove 21. The rib 3 is bent inward and engaged with the avoidance groove 21, thereby enhancing the connection stability between the metal 1 and the backlight plastic frame 2 and preventing loosening between the two.

[0025] In addition, the avoidance groove 21 of the backlight plastic frame 2 cooperates with the opening groove 11 of the metal frame 1 to prevent the metal frame 1 and the backlight plastic frame 2 from being misaligned during assembly, thereby guiding the installation of the metal frame 2 .

[0026] Specifically, the horizontal height of the top of the rib 3 is less than or equal to the horizontal height of the top of the backlight frame 2, so that the rib 3 will not protrude from the backlight frame 2, ensuring the smoothness and consistency of the overall appearance of the component and facilitating the subsequent installation of the display device.

[0027] Preferably, the longitudinal cross-section of the metal frame 1 can be set to be in a “]” shape.

[0028] The metal frame 1 can be preferably made of metal iron. Metal iron has high strength and rigidity, can provide good structural support, can maintain good stability and durability during use, and also has good thermal conductivity, can help dissipate heat, is easy to process and low cost, and is suitable for large-scale production.

[0029] The material of the backlight plastic frame 2 can be set to polypropylene, polycarbonate or polyester.

[0030] The backlight frame 2 of this embodiment is preferably made of polycarbonate. Compared with polypropylene and polyester, polycarbonate has higher mechanical strength and impact toughness, can effectively protect the backlight, reduce the risk of physical damage, and is easy to process and shape. It also exhibits good stability at higher temperatures, making it suitable for most working environments of backlights. Of course, in other embodiments, the material of the backlight frame 2 is not limited according to actual needs.

[0031] Preferably, the horizontal height of the top of the metal frame 1 can be equal to the horizontal height of the top of the backlight plastic frame 2. Of course, in other embodiments, the horizontal height of the top of the metal frame 1 can be higher than the horizontal height of the top of the backlight plastic frame 2, and this embodiment does not limit it.

[0032] To sum up, the ribs of the present invention can clamp the backlight source rubber frame and prevent it from loosening. Compared with the traditional backlight source rubber frame being buckled into the metal frame, which generates powder chips entering the backlight and causing defects, this embodiment can avoid the problem of powder chips entering the backlight source caused by the traditional connection method. It not only enhances the stability of the connection between the metal frame and the backlight source rubber frame, improves the assembly efficiency of the components, but also helps to reduce the defective rate.

[0033] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
