An embodiment of the present invention provides a display device. As shown inFIG.1,FIG.1is a schematic structural diagram of a display device provided by an embodiment of the present invention. The display device1includes a rear shell2and a support plate3.

The rear shell2includes a first rear shell21, a second rear shell22, and a third rear shell23. Two ends of the third rear shell23are rotatably connected to the first rear shell21and the second rear shell22, respectively.

As shown inFIG.1, the first rear shell21includes a first bottom surface211and two first side surfaces212and213respectively connected to the first bottom surface211. In an embodiment, the first rear shell2further includes a side surface214. The first side surface212and the first side surface213are oppositely arranged. The side surface214connects not only the first side surface212and the first side surface213but also the first bottom surface211. The side surface214, the first side surface212, and the first side surface213form a three-sided surrounding structure of the first rear shell21. The first side surfaces212and213are each provided with a first chute215. The first chute215may be a linear chute or an arc-shaped chute, which is specifically set according to a folding angle of the display device1. It should be noted that the first chute215can be replaced with a sliding rail or similar sliding mechanism. The first side surfaces212and213are each provided with a first through hole216.

As shown inFIG.1, the second rear shell22includes a second bottom surface221and two second side surfaces222and223respectively connected to the first bottom surface221. In an embodiment, the second rear shell22further includes a side surface224. The second side surfaces222and223are oppositely arranged. The side surface224is not only connected to the second side surfaces222and223but also connected to the second bottom surface221. A second chute225is also provided on the second side surfaces222and223respectively. The second chute225may be a linear chute or an arc-shaped chute, which is specifically set according to a folding angle of the display device1. In order to allow the first rear shell21and the second rear shell22to rotate at an equal angle, the first chute215and the second chute225may be provided as chutes of the same shape. It should be noted that the second chute225can be replaced by a sliding mechanism such as a sliding rail. The second side surfaces222and223are each provided with a second through hole226.

The third rear shell23includes a third bottom surface231and third side surfaces232and233connected to the third bottom surface231respectively. The third side surfaces232and233are oppositely arranged. Each of the third side surfaces232and233is provided with a first rotating shaft groove234and a second rotating shaft groove235. The third side surface232and the side surface233are each provided with a third through hole236and a fourth through hole237. The third through hole236and the first through hole216are dimensionally matched. The fourth through hole237and the second through hole226are dimensionally matched.

In an embodiment, the display device1further includes a plurality of rotating shafts. The first through hole216and a corresponding third through hole236are fixed together by a corresponding rotating shaft. The second through hole226and a corresponding fourth through hole237are fixed together by a corresponding rotating shaft.

When the first rear shell21, the second rear shell22, and the third rear shell23are at a same horizontal plane, the first rear shell21and the second rear shell22completely house the third rear shell23.

As shown inFIG.2, a corner a of the first side surfaces212and213of the first rear shell21close to the second rear shell22is rounded. A corner b of the second side surfaces222and223of the second rear shell22close to the first rear shell21is rounded. This arrangement can prevent the first rear shell21and the second rear shell22from coming into contact with each other.

The support plate3plays a supporting role, and its constituent materials may use one or more of the following materials with high hardness and light weight: aluminum alloy, iron-nickel alloy, stainless steel, and amorphous material.

As shown inFIG.1toFIG.3, the support plate3includes a first support plate31and a second support plate32. The first support plate31is provided on the first rear shell21. An end of the first support plate31is rotatably connected to the third rear shell23, and another end of the first support plate31is slidingly connected to the first rear shell21.

Referring toFIG.1andFIG.2, a first slider311is provided on each side of the first support plate31. The first slider31is inserted into a corresponding first chute215, so that an end of the first support plate31is slidingly connected to the first rear shell21. A first rotating shaft312is provided on each side of the first support plate31. The first rotating shaft312is inserted into a corresponding first rotating shaft groove234so that an end of the first support plate31is rotatably connected to the third rear shell23.

A second slider321is provided on each side of the second support plate32. The second slider321is inserted into a corresponding second chute225, so that an end of the second support plate32is slidingly connected to the second rear shell22. A second rotating shaft322is provided on each side of the second support plate32. The second rotating shaft322is inserted into a corresponding second rotating shaft groove235so that an end of the second support plate32is rotatably connected to the third rear shell23.

In an embodiment, as shown inFIG.4andFIG.5, the display device1further includes a display screen4. The display screen4is disposed on a side of the support plate3away from the rear shell2. The display screen4includes a bending area and a non-bending area. The display screen located in the bending area is opposite to the support plate3and is not fixed with the support plate3.

A process of the rear shell2, the support plate3, and the display screen4cooperating with each other during a bending process of the display device1will be described in detail below.

As shown inFIG.3andFIG.5, the display device1is in a flat state, and at this time, the support plate3can be used to support the display screen4provided thereon. The first slider311is at the top of the first chute215, and the second slider321is at the top of the second chute225.

The first rear shell21and the second rear shell22completely house the third rear shell23, so that there is only one gap on the back of the display device1, and only the gap can be treated to prevent invasion of water and oxygen.

As shown inFIG.2, the display device1is in a folded state. During a folding process fromFIGS.3-5toFIG.2, the rotating shaft inserted through the first through hole216and the third through hole236drives the first rear shell21to rotate toward the second rear shell22. The rotating shaft inserted through the second through hole226and the fourth through hole237drives the second rear shell22to rotate toward21. That is, the first rear shell21and the second rear shell22are close to each other.

The first slider311slides along the top of the first chute215to the bottom. The first rotating shaft312inserted in the first rotating shaft groove234rotates. The first slider311and the first rotating shaft312cooperate with each other to slide the first support plate31to the outside. Similarly, the second slider321slides along the top of the second chute225toward the bottom. The second rotating shaft322inserted in the second rotating shaft groove235rotates. The second slider321and the second rotating shaft322cooperate with each other, so that the second support plate32also slides outward. As shown inFIG.2, an accommodating space with an upward opening larger than a downward opening is formed between the first support plate31and the second support plate32. The above-mentioned accommodating space is large enough, so that the display screen4in the bending area can form a water drop shape, and the display screen4is prevented from being damaged during the bending process.

In the display device of embodiments of the present invention, the support plate is rotatably connected to the third rear shell, and the support plate is slidingly connected to the first rear shell and the second rear shell respectively. This allows the display device to form a folded structure, which improves portability of the display device. Further, during the bending process, the first support plate and the second support plate move outward, which can give the display screen enough bending space and improve a bending performance of the display screen.

In summary, although the present invention has been disclosed as the preferred embodiments above, the above preferred embodiments are not intended to limit the present invention. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is subject to the scope defined by the claims.
