The metal plate 32 is disposed in the recess 314 and the back surface of the metal plate 32 is flush with the back surface of the plastic case 31, so that the entire rear case 3 has a small thickness.

The thickness of the metal plate 32 is smaller than that of the back plate 312 of the plastic shell 31, and in the embodiment, the thickness of the metal plate 32 is less than or equal to 0.6 mm.

Fig. 5 is a schematic diagram of a back structure of a second embodiment of the display device of the present invention. Fig. 6 is a schematic diagram of a back structure of a third embodiment of the display device of the present invention. Fig. 7 is a schematic diagram of a back structure of a fourth embodiment of the display device of the present invention.

Referring to fig. 5 to 7, the metal plate 32 may have a polygonal shape such as a rectangular shape or a rectangular shape, or may have another irregular shape.

In some embodiments, the metal plate 32 and the plastic housing 31 are integrally injection molded. Specifically, when the plastic housing 31 is injection molded, the metal plate 32 is placed as an insert in a corresponding injection mold, so that the metal plate 32 and the plastic housing 31 are injection molded to form an integral structure.

In other embodiments, the plastic housing 31 is injection molded, and the corresponding mounting position is reserved on the injection molded plastic housing 31, and then the metal plate 32 is adhered to the plastic housing 31.

The insulating pad 33 is fixed and attached to the side of the metal plate 32 facing the power supply board 2, and is made of an insulating material for blocking the metal plate 32 and the power supply board 2, thereby playing an insulating role. In some embodiments, the insulating pad 33 may be adhered to the metal plate 32.

The insulating spacer 33 may be a PET insulating spacer, a nylon insulating spacer, a PC insulating spacer, or highland barley paper. The insulating spacer 33 is in the window 311.

Referring to fig. 4, in some embodiments, the thickness of the insulating pad 33 is smaller than the depth of the window 311, the thinner the thickness of the insulating pad 33 is, the thinner the total thickness of the insulating pad 33 and the metal plate 32 is, and the smaller the distance between the back surface of the metal plate 32 and the power plate 2 is when the gap between the insulating pad 33 and the power plate 2 is constant.

In this embodiment, the thickness of the insulating spacer 33 is 0.5mm, the size and shape of the insulating spacer 33 are adapted to the size and shape of the window 311, and the edge of the insulating spacer 33 abuts against the edge of the window 311. In some embodiments, the edge of the insulating gasket 33 is larger than the edge of the window 311, so that the insulating gasket 33 can better close the window 311.

In one embodiment, the thickness of the back plate 312 of the plastic housing 31 is 3mm, and when the metal plate 32 is not used, the shortest distance from the power supply board 2 to the back plate 312 of the plastic housing 31 is 6mm, which is the safety distance, plus the thickness of the plastic housing 31 is 3mm, and the total thickness is 9 mm. When the metal plate 32 of 0.6mm and the insulating pad 33 of 0.5mm are used, the distance from the power supply plate 2 to the insulating pad 33 is controlled to be 1 mm; at this time, when the distance from the power board 2 to the back surface of the metal plate 32 is 2.1mm, and the back surface of the metal plate 32 is flush with the back surface of the plastic housing 31, compared with the rear housing 3 completely made of plastic, the thickness of the rear housing 3 made of the plastic housing 31, the metal plate 32 and the insulating spacer 33 can be reduced by 6.9mm, and the thickness is greatly reduced, so that the thickness of the whole display device 100 is greatly reduced.

According to the technical scheme, the invention has at least the following advantages and positive effects:

the utility model discloses in the display device 100 embodiment, power strip 2 is fixed in the back of display device main part 1, the back of display device main part 1 is fitted to plastic housing 31 lid, and cover this power strip 2, counterpoint power strip 2 has seted up the window 311 that link up on the plastic housing 31, metal sheet 32 is fixed in the back of plastic housing 31, and seal this window 311, make power strip 2 to the shortest distance between plastic housing 31 (the distance of the peak of power strip 2 to the back plate 312 of plastic housing 31), become the distance between power strip 2 to metal sheet 32, do not stipulate corresponding safe distance between metal sheet 32 to power strip 2 peak. The provision of the metal plate 32 eliminates the problem that since the plastic case 31 is made of plastic, a safety distance needs to be provided between the plastic case 31 and the power supply board 2. The insulating pad 33 is disposed in the window 311 and attached to the metal plate 32, so that the distance between the metal plate 32 and the power board 2 can be designed to be small enough, the plastic shell 31 and the power board 2 are closer, the thickness of the whole display device 100 is smaller, the electronic device is more attractive, and the carrying and the transportation are convenient.

Wherein, because metal has better radiating effect for plastics, metal sheet 32 sets up power strip 2 counterpoint for power strip 2 has better radiating effect.

In addition, the peripheral edge of the metal plate 32 exceeds the edge of the window 311, so that the metal plate 32 covers and closes the window 311, the metal plate 32 and the plastic shell 31 have larger contact area and attachment area, and the metal plate 32 is ensured to be fixed on the plastic shell 31 more firmly. Meanwhile, the arrangement of the metal plate 32 enhances the structural strength of the whole rear case 3, so that the rear case 3 is not easily damaged.

Compared with a metal rear shell, the plastic shell 31 can be processed into a complex shape and is low in cost. By using the plastic housing 31, the metal plate 32 and the insulating spacer 33, the thickness of the display device 100 is reduced on the premise of saving cost, and the economic benefit is improved.
