[0002] To meet the design requirements of high-end televisions for aesthetics, thinness, and efficient heat dissipation, more and more manufacturers are using metal back covers, such as aluminum alloy back covers. These back covers are usually manufactured through a stamping process. However, during the stamping process, the metal material undergoes elastic deformation before plastic deformation. When the stamping pressure is unloaded, the metal material will spring back due to elastic recovery, resulting in a bouncing phenomenon. This causes the actual shape of the back cover to deviate from the design dimensions of the mold cavity. Specifically, this manifests as critical dimensional problems such as substandard bending angles, excessive flatness tolerances, or misalignment of assembly interfaces. These issues directly affect the assembly accuracy of the back cover and the entire television, ultimately impacting the overall quality of the television. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] This utility model discloses a back cover, including a back plate 1. The edge of the back plate 1 is provided with elastic buckles that engage with the snap-fit ​​grooves of the panel, enabling quick assembly of the back plate 1 and the panel. After the back plate 1 is snapped into place with the panel, an internal cavity is formed to prevent the display screen, circuit board, etc., from being impacted by external forces or from dust intrusion. It should be noted that the outer surface of the back plate 1 in this document refers to the surface of the back plate 1 away from the panel.

[0043] As attached Figures 1 to 4 As shown, the outer surface of the back plate 1 is provided with a number of first ribs 11 and a number of second ribs 12. All the first ribs 11 and all the second ribs 12 are arranged intersectingly, that is, the intersecting rib design is adopted. This can not only enhance the bending resistance of the back plate 1 in different directions, effectively suppress uneven deformation during the stamping process, and reduce the risk of warping caused by stress concentration, but also use the intersecting structure to disperse the forming stress, reduce the elastic recovery after stamping, and reduce the risk of the back plate 1 bouncing when demolding.

[0044] Along the thickness direction of the back plate 1, the first rib 11 and the second rib 12 maintain a set height difference relative to the outer surface, i.e., a stepped rib design is adopted to achieve differentiated adjustment of the deformation resistance of different areas. The higher rib acts as the main load-bearing structure to resist overall bending deformation, while the lower rib helps to suppress local rebound. The synergistic effect of the two can effectively constrain material flow and reduce the bouncing problem caused by uneven plastic deformation. Specifically, the preferred height difference is 2mm, but it is not limited to this.

[0045] This utility model adopts a combination of cross layout and height difference control to reduce the risk of back plate 1 bouncing during stamping, improve the dimensional stability of back plate 1 during the stamping stage, reduce the error between the outer dimensions of back plate 1 and the design dimensions of mold cavity, effectively improve the assembly accuracy of back cover and whole machine, thereby improving the overall quality of machine.

[0046] As a preferred embodiment, as shown in the appendix Figure 1 and 2 As shown, the first rib 11 includes a first left diagonal rib 111, a first right diagonal rib 112, and a first longitudinal rib 113. The first left diagonal rib 111 and the first right diagonal rib 112 are distributed along the length of the back plate 1 and are set at an angle to form a figure-eight structure. The first longitudinal rib 113 extends along the length of the back plate 1 and is integrally connected between the first left diagonal rib 111 and the right diagonal rib. The first left diagonal rib 111 and the first longitudinal rib 113, as well as the first right diagonal rib 112 and the first longitudinal rib 113, are all intersected and connected, so that the first rib 11 also adopts a cross-rib design, which improves the bending strength of the back plate 1.

[0047] As a preferred embodiment, as shown in the appendix Figure 1 and 2 As shown, the second rib 12 includes a second left diagonal rib 121 and a second right diagonal rib 122. The second left diagonal rib 121 and the second right diagonal rib 122 are distributed along the length of the back plate 1 and are set at an angle to form a figure-eight structure. The second left diagonal rib 121 and the second right diagonal rib 122 are located between the first left diagonal rib 111 and the first right diagonal rib 112. The second left diagonal rib 121 is parallel to the first left diagonal rib 111, and the second right diagonal rib 122 is parallel to the first right diagonal rib 112. In this way, the first rib 11 acts as the main load-bearing structure to resist the bending deformation of the back plate 1, while the second rib 12 assists in suppressing the local rebound of the back plate 1. The first rib 11 and the second rib 12 work together to effectively reduce the bouncing problem caused by uneven plastic deformation of the back plate 1. In addition, the vertical distance between the first left oblique rib 111 and the second left oblique rib 121 is equal to the vertical distance between the first right oblique rib 112 and the second right oblique rib 122, ensuring that the ribs on the outer surface of the back plate 1 are evenly distributed.

[0048] As a preferred embodiment, as shown in the appendix Figure 1 and 2 As shown, the second left diagonal rib 121 and the second right diagonal rib 122 intersect the first longitudinal rib 113. The outer surfaces of the second left diagonal rib 121 and the second right diagonal rib 122 are flush, and both are lower than the outer surface of the first longitudinal rib 113. Furthermore, the outer surfaces of the second left diagonal rib 121 and the second right diagonal rib 122 maintain a set height difference with the outer surface of the first longitudinal rib 113, thus achieving differentiated adjustment of the deformation resistance of different areas of the back plate 1. In this text, the outer surfaces of the second left diagonal rib 121 and the second right diagonal rib 122 refer to the sides away from the back plate 1, and the outer surface of the first longitudinal rib 113 refers to the side of the first longitudinal rib 113 away from the back plate 1.

[0049] As a preferred embodiment, as shown in the appendix Figure 1 and 2 As shown, the outer surface edge of the back plate 1 is also provided with edge ribs 13. The edge ribs 13 are closed rectangular structures, which reduce the risk of warping caused by edge deformation of the back plate 1 during stamping and effectively improve the bending strength of the back plate 1. The first rib 11 and the second rib 12 are both located inside the edge ribs 13, and the outer surfaces of the first rib 11 and the second rib 12 are flush with the outer surface of the edge ribs 13, so that any two of the edge ribs 13, the first rib 11 and the second rib 12 form a cross rib structure, which effectively suppresses the back plate 1 from bouncing during demolding.

[0050] As a preferred embodiment, as shown in the appendix Figure 1 and 2 As shown, the edge rib 13 includes a left rib 131, an upper rib 132, a right rib 133, and a lower rib 134 connected vertically end to end. The left rib 131 is parallel to the right rib 133, and the upper rib 132 is parallel to the lower rib 134. The two ends of the first left oblique rib 111 are respectively connected to the left rib 131 and the upper rib 132; the two ends of the first right oblique rib 112 are respectively connected to the right rib 133 and the upper rib 132; the two ends of the second left oblique rib 121 are respectively connected to the upper rib 132 and the lower rib 134; the two ends of the second right oblique rib 122 are respectively connected to the upper rib 132 and the upper rib 134, so that the edge rib 13, the first rib 11, and the second rib 12 form a cross rib structure.

[0051] As a preferred embodiment, as shown in the appendix Figure 3 and 4As shown, the back cover also includes a back shell 2. The outer surface of the back panel 1 is provided with a mounting groove 14, and the back shell 2 is fastened into the mounting groove 14. The groove edge of the mounting groove 14 is raised to form a shielding rib 15, which is used to shield the gap between the mounting groove 14 and the back shell 2 to prevent the back cover from leaking light.

[0052] As a preferred embodiment, as shown in the appendix Figure 1 and 2 As shown, the shielding rib 15 has a U-shaped structure and includes a left shielding rib 151, an upper shielding rib 152, and a right shielding rib 153 connected vertically in sequence. The upper shielding rib 152 extends along the length of the back plate 1. The two ends of the upper shielding rib 152 are respectively connected to the second left oblique rib 121 and the second right oblique rib 122. The two ends of the left shielding rib 151 are respectively connected to the second left oblique rib 121 and the lower rib 134. The two ends of the right shielding rib 153 are respectively connected to the second right oblique rib 122 and the lower rib 134, so that the shielding rib 15 and the second rib 12 form a cross rib structure.

[0053] In a preferred embodiment, the outer side of the shielding rib 15 is flush with the outer side of the second rib 12. This flush design ensures that the two ribs work together to withstand external pressure or impact, avoiding stress concentration at a single point, reducing the risk of localized breakage of the shielding rib 15 or the second rib 12 during drop impacts, extending the service life of the back cover, and improving the bending strength of the back cover. It should be noted that the outer side of the shielding rib 15 refers to the side of the shielding rib 15 away from the back panel 1, and the outer side of the second rib 12 refers to the side of the second rib 12 away from the back panel 1.
