Detailed Description

As shown in fig. 1, a display device according to an embodiment of the present invention includes a transparent cover plate 1, a display screen 2, a decoration 3, a metal bracket 4, a PCB 5, and a rear cover 6.

In this embodiment, the transparent cover plate 1 is a glass cover plate, or a plastic cover plate in other embodiments, and the display screen 2 is attached to the inner side of the transparent cover plate 1.

As shown in fig. 2, the decoration 3 includes a body 31, the body 31 is a hollow sheet structure, the hollow portion corresponds to the display screen 2, the outer edge of the body 32 is provided with a first protrusion 32, the first protrusion 32 is an appearance piece, that is, a so-called silver ring, and a second surface of the first surface and/or the second surface of the outer side of the first protrusion 32, which is away from the metal bracket 4, is an appearance surface, and is subjected to a painting process, such as spraying silver paint.

The body 31 and the metal bracket 4 are connected by riveting or bonding, in this embodiment, the body 31 and the metal bracket 4 are connected by riveting, and in other embodiments, the body 31 and the metal bracket 4 may be connected by bonding.

The edge of the hollow portion of the body 31 is provided with a plurality of riveting columns 33 extending towards the metal support 4, the corresponding position of the metal support 4 is provided with a first through hole 412, as shown in fig. 5, the riveting columns 33 pass through the first through hole 412, as shown in fig. 6, and the body 31 and the metal support 4 are fixedly connected together through hot riveting.

As shown in fig. 4, the stud 33 includes three segments: the rivet comprises a first section 331, a second section 332 and a third section 333, wherein the second section 332 is a bending portion so that the rivet column 33 is bent inward, the first end of the rivet column 33 is located at the inner side of the second end, the first end is a riveting portion, and the second end is a connecting portion between the rivet column 33 and the body 31.

Such a structure can ensure that there is enough space outside the first through-hole 412 of the metal bracket 4 to ensure the strength of the rivet connection. As shown in fig. 3, the metal bracket 4 protrudes outward from the side wall 411 of the first through hole 412, so that the space between the first through hole 412 and the side wall 411 is further increased, and the strength of the caulking connection is ensured.

In order to ensure the strength of the rivet column 33, the rivet column 33 is provided with a plurality of reinforcing ribs, and the two sides of the first section 331 are provided with first reinforcing ribs 3311, as shown in fig. 5; the third section 333 is provided with second reinforcing ribs 3331 on the inner side, as shown in fig. 4, and third reinforcing ribs 3332 on the outer side, as shown in fig. 5.
