[0034] Please refer to Figures 1 to 7In the first embodiment of the present application, a lightweight plastic iron 10 is provided, comprising an iron frame 20 and a plastic frame 30. The iron frame 20 comprises a bottom plate 21 and a side frame 22. The bottom plate 21 is provided with a load-bearing area 211 and a weight-reducing area 212. The weight-reducing area 212 is located inside the load-bearing area 211. The area of the weight-reducing area 212 is no more than 50% of the area of the bottom plate 21. The weight of the weight-reducing area 212 is 40%-60% of the weight of the load-bearing area 211. The side frame 22 is provided at the edge of the load-bearing area 211 away from the weight-reducing area 212. The plastic frame 30 is provided on the inner surface of the side frame 22. Thus, while ensuring the structural strength of the plastic iron, the weight of the plastic iron is reduced, providing a guarantee for the lightweighting of the backlight source 1.
[0035] Please refer to Figure 2 In some embodiments, the weight-reducing region 212 is configured as a single through-hole, and the area of the single through-hole is no greater than 50% of the area of the base plate 21. This effectively reduces the weight of the rubber-iron while retaining sufficient load-bearing area 211 and ensuring that the rubber-iron has the required structural strength. Specifically, the through-hole is configured as a square hole, a diamond hole, a rectangular hole, etc., which can reduce the weight of the rubber-iron by 45%-60%. Preferably, the single-hole weight-reducing region 212 can also be embedded with a heat sink, such as a graphene sheet, copper foil, aluminum foil, etc., to improve the heat dissipation efficiency of the rubber-iron.
[0036] Please refer to Figure 3 In some embodiments, the weight-reducing region 212 is configured as a plurality of through-holes, spaced apart, with the area of the through-holes no greater than 50% of the area of the base plate 21. Specifically, the through-holes can be configured as round, square, diamond-shaped, or rectangular holes, which can reduce the weight of the rubber-iron by 40%-50%. This effectively reduces the weight of the rubber-iron while ensuring sufficient structural strength.
[0037] In some embodiments, the thickness of the weight-reducing region 212 is less than the thickness of the load-bearing region 211. By thinning the weight-reducing region 212, weight reduction is achieved, thereby effectively reducing the weight of the rubber-iron while ensuring sufficient structural strength of the rubber-iron.
[0038] In some embodiments, the thickness of the weight-reducing region 212 is 60%-75% of the thickness of the load-bearing region 211, thereby ensuring that the rubber-iron has sufficient structural strength. Specifically, the thickness of the load-bearing region 211 and the side frame is set to 0.25-0.4 mm, and the thickness of the weight-reducing region 212 is 0.15-0.3 mm, thereby reducing the weight of the rubber-iron by approximately 40%-50%.
[0039] Please refer to Figure 4-Figure 7 In some embodiments, the side frame 22 includes a side frame body 221 and a bent portion 222. One end of the side frame body 221 is disposed at an edge of the load-bearing region 211 away from the weight-reducing region 212. The bent portion 222 is disposed at the end of the side frame body 221 away from the load-bearing region 211. The bent portion 222 is bent toward the plastic frame 30 and embedded in the plastic frame 30. This effectively enhances the structural strength of the plastic-iron, ensuring that the plastic-iron has sufficient structural strength while reducing its weight.
[0040] In some embodiments, the thickness of the weight-reducing region 212 is 60%-75% of the thickness of the load-bearing region 211. This ensures that the rubber-iron has sufficient structural strength. Specifically, the thickness of the load-bearing region 211 and the side frame is set to 0.25-0.4 mm, and the thickness of the weight-reducing region 212 is 0.15-0.3 mm, thereby reducing the weight of the rubber-iron by approximately 40%-50%. The side frame 22 includes a side frame body 221 and a bent portion 222. One end of the side frame body 221 is disposed at an edge of the load-bearing region 211 away from the weight-reducing region 212. The bent portion 222 is disposed at an end of the side frame body 221 away from the load-bearing region 211. The bent portion 222 is bent toward the rubber frame 30 and embedded in the rubber frame 30. This effectively enhances the structural strength of the rubber-iron, ensuring that the rubber-iron has sufficient structural strength while reducing its weight.
[0041] In some embodiments, the bent portion 222 and the side frame body 221 form an angle toward the plastic frame 30, and the angle is no greater than 90 degrees. This can further enhance the connection strength between the bent portion 222 and the plastic frame 30, thereby ensuring the structural strength of the plastic-iron.
[0042] Please refer to Figure 8 In the second embodiment of the present application, a backlight source 1 is also provided, which includes the lightweight rubber iron 10 provided in the first embodiment of the present application, thereby reducing the weight of the backlight source 1 to meet the requirements of the lightness and thinness of the backlight source 1; please refer to the first embodiment of the present application for details.
[0043] A display device is further provided in the third embodiment of the present application, which includes the backlight source 1 provided in the second embodiment of the present application, thereby reducing the weight of the display device to meet the demand for thinness and lightness of the display device.
[0044] The fourth embodiment of the present application further provides a smart mobile terminal, which includes the backlight source 1 provided in the second embodiment of the present application, thereby reducing the weight of the display device to meet the lightweight and thin requirements of the smart mobile terminal.
[0045] In summary, the present application provides a lightweight plastic iron, a backlight source, a display device and a smart mobile terminal, wherein the lightweight plastic iron comprises: an iron frame, wherein the iron frame comprises a bottom plate and a side frame, wherein the bottom plate is provided with a load-bearing area, and a weight-reducing area located inside the load-bearing area, wherein the area of the weight-reducing area is not greater than 50% of the area of the bottom plate, and the weight of the weight-reducing area is 40%-60% of the weight of the load-bearing area, and the side frame is provided at the edge of the load-bearing area away from the weight-reducing area; and a plastic frame, wherein the plastic frame is provided at the inner surface of the side frame. By providing a weight-reducing area on the bottom plate of the iron frame, and controlling the area ratio of the weight-reducing area, and controlling the weight of the weight-reducing area to be less than the weight of the load-bearing area, the bottom plate is partially reduced in weight, thereby reducing the weight of the plastic iron while ensuring the structural strength of the plastic iron, thereby providing a guarantee for the lightweighting of the backlight source.
