Problems solved by technology

[0007] In the process of realizing the present invention, the inventor found that the above-mentioned method has the following disadvantages: in the first method, a fixing piece needs to be added, which increases the cost. Specification limitation; the second method and the third method are not suitable for use on TVs with ART structure, because in TVs with ART structure, the rear shell is embedded in the bottom plate of the middle frame, so that there is no correspondence between the bottom plate and the rear shell part of the cable can catch the power cord or the fixing on it

Embodiment 1

[0030] Such as Figure 3 to Figure 8 As shown, this embodiment provides a display device, including a display screen (not shown in the figure), a housing and a power cord 1, such as image 3 As shown, the casing includes a middle frame 1 and a rear case 4, the middle frame 2 wraps the display screen and is fixedly connected with the display screen, and the rear case 4 is fixedly connected with the display screen.

[0031] Among them, such as image 3 As shown, the middle frame 2 includes a side plate and a bottom plate connected with the side plate and having a through hole in the middle, the side plate is wrapped around the periphery of the display screen, and the bottom plate is connected to the back of the display screen The board is fixedly connected, and the rear shell 4 covers the through hole.

[0032] Such as Figure 7 As shown, the base plate is provided with an outlet 213, such as Figure 8 As shown, the power cord 1 is provided with a fixing part 11, such as I...

Embodiment 2

[0051] This embodiment provides a display device. The difference from Embodiment 1 is that in the display device in this embodiment, the middle frame is made of a material with weak strength, such as: plastic material, plastic material The strength of the middle frame is lower than that of the metal material. In this way, when the power cord is subjected to external pulling force, the strength of the middle frame is not enough to resist the external pulling force. Under the action of external pulling force, the middle frame is easy to be deformed or The breakage of the boss causes the power cord to fall off, and the falling off and exposure of the 220V power cord of the display device will cause great danger. Therefore, in this embodiment, the boss needs to be further fixed.

[0052] Preferably, in this embodiment, the boss is connected to the back panel of the display screen.

[0053] further, such as Image 6 As shown, the boss 210 is fixedly connected to the back panel 4 o...

Embodiment 3

[0058] This embodiment provides an ART-structured television, including the display device described in Embodiment 1 or Embodiment 2.

[0059] To sum up, in the display device provided by the above embodiments of the present invention, the outlet of the power cord is set on the bottom plate of the middle frame of the display device, and the power cord is fixed on the bottom plate near the outlet, so that the outlet of the power cord is connected to the outlet. The distance between the fixed points of the power cord is relatively short, and the space for the power cord to expand and contract between the power cord outlet and the fixed point of the power cord is reduced, which effectively prevents the power cord from expanding and contracting to the inside of the display device, and prevents the power cord from collapsing after the power cord is stretched inward. The safety problems caused by the contact and collision of other parts inside the display device; there is a boss on t...

Abstract

The invention provides a display device and a TV, wherein a middle frame of the display device includes a side plate and a bottom plate connected with the side plate and having a through hole in the middle, the side plate wraps the display screen, and the bottom plate is fixedly connected with the display screen, The rear shell covers the through hole of the bottom plate; the bottom plate is provided with a wire outlet, the side wall of the through hole of the bottom plate is provided with a boss, and the power line is fixed on the boss and located between the boss and the rear shell, and the power line is The distance between the fixed position on the boss and the outlet is less than 30mm. In the display device provided by the present invention, the cable outlet is arranged on the bottom plate of the middle frame, and the power cable is fixed on the bottom plate near the cable outlet, which can prevent the power cable from expanding inwardly, and meanwhile the power cable is located in the narrow space between the boss and the rear shell. In the space, the power cord can be further prevented from stretching inwardly, which solves the safety problem caused by the power cord stretching inward; the power cord is fixed in the casing without affecting the appearance of the display device; the power cord fixing method is suitable for TVs with ART structure .

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a display device capable of preventing a power cord from being stretched inward and a television set comprising the display device. Background technique [0002] In LCD TVs, the power cord is usually directly fixed on the LCD screen through the fixed lugs on the power cord, or fixed on the internal bracket, such as figure 1 As shown, then lead out the power cord 1' at the opening of the rear case 4', and finally use the cover plate 41' to seal the opening on the rear case 4'. In the TV with ART structure (referring to no front shell, the middle frame wraps the display screen, and the middle frame includes side panels and bottom panels, the side panels wrap around the sides of the display screen, the bottom panel is fixed on the back of the display screen, the rear shell is embedded in the bottom panel and connected to the bottom panel spliced ​​TV), such as figure 2 As shown...
