Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, the present embodiment provides a display device, which includes a base 10, a rotating shaft assembly 11 is disposed on one side of the base 10, and the base 10 is hinged to a display screen 12 and a supporting member 13 through the rotating shaft assembly 11.

As a specific application scenario of the embodiment, the display 12 may be understood as an extended screen, which displays a picture on a computer through a data line (e.g., a high definition line).

As an alternative, the other side of the base 10 is provided with a data interface, which includes but is not limited to: high-definition data interface, USB data interface and power interface.

In normal use, the display screen 12 can be opened, so that the display screen 12 is approximately in a vertical state or a backward state (inclined to the right in fig. 1); at this time, the display 12 is supported by the torsional force provided by the hinge between the hinge assembly 11 and the display 12. Since the center of gravity of the display 12 is located on the base 10, the display 12 can be supported by only the base 10 without opening the support 13, and the support 13 can be accommodated in the accommodating groove 101.

When the display 12 needs to be tilted forward (tilted to the left in fig. 1), the center of gravity of the display 12 falls outside the base 10, and in order to prevent or partially prevent the display 12 from tilting, the supporting member 13 may be opened, so that the supporting member 13 is unfolded as shown in fig. 1, and is supported on a table top by the supporting inclined surface 131 of the supporting member 13, thereby assisting the base 10 to support the display 12.

In this embodiment, support piece 13 and display screen 12 are articulated with base 10 respectively, and display device not only can fold, conveniently carries, when display screen 12 leans forward, can also support through support piece 13 moreover, prevents that display screen 12 from empting. Meanwhile, the supporting piece 13 and the display screen 12 are hinged with the base 10 through the same rotating shaft assembly 11, so that the number of parts of the rotating shaft assembly 11 is reduced, and the processing cost and the assembling cost are reduced.

Referring to fig. 2 to 4, in another embodiment of the present application, a specific structure of the rotating shaft assembly 11 is disclosed, which includes:

a pair of first mandrels 111 respectively located at two ends of one side of the base 10, and two ends of the bottom of the display screen 12 are respectively fixedly connected with the pair of first mandrels 111 through a rotating frame 115;

a pair of second mandrels 112, the pair of second mandrels 112 is arranged between the pair of first mandrels 111, and two ends of the supporting piece 13 are respectively fixedly connected with the pair of second mandrels 112;

a pair of fixing frames 113, wherein the pair of fixing frames 113 are fixedly connected with the base 10 through a connecting sheet 114 respectively; the pair of fixing frames 113 are respectively sleeved on the pair of first mandrels 111 and are in interference fit with the pair of first mandrels 111; the pair of fixing frames 113 are further respectively sleeved on the pair of second mandrels 112 and are in interference fit with the pair of second mandrels 112.

The connecting piece 114 can increase the strength of the housing, and can change the original metal alloy material of the housing into a plastic material, thereby reducing the cost.

In this embodiment, when the operation display screen 12 rotates, the rotating frame 115 rotates along with the rotation and drives the first spindle 111 to rotate, and the first spindle 111 and the fixing frame 113 are in interference fit with each other and provide a torque force for supporting the display screen 12.

When the supporting member 13 is needed to be used, the operation supporting member 13 rotates, and the second spindle 112 and the fixing frame 113 are in interference fit and provide torsion.

In this embodiment, the supporting member 13 and the display 12 are hinged to the base 10 through the same fixing frame 113, so that the number of parts of the rotating shaft assembly 11 is reduced, and the processing cost and the assembling cost are reduced.

As an optional manner of this embodiment, the pair of fixing frames 113 are further respectively provided with a first sleeve 1131 for being sleeved on the pair of first mandrels 111, the first sleeve 1131 is connected to a first limiting block 1132 for limiting a tilt angle range of the display screen 12 in an extending manner, and the pair of first mandrels 111 are further respectively provided with a first protrusion 1111 matched with the first limiting block 1132.

Optionally, when the display screen 12 tilts forward, the maximum angle at which the display screen 12 tilts forward can be limited by the cooperation of the first limiting block 1132 and the first protrusion 1111.

As an optional manner of this embodiment, the pair of fixing frames 113 are further respectively provided with a second sleeve 1134 for being sleeved on the pair of second mandrels 112, the second sleeve 1134 is connected to a second limiting block 1135 for limiting the expansion angle range of the supporting member 13 in an extending manner, and the pair of second mandrels 112 are further respectively provided with a second protrusion 1121 matched with the second limiting block 1135.

Optionally, the second limiting block 1135 is matched with the second protrusion 1121, so that the maximum unfolding angle of the supporting member 13 can be limited, and the supporting member 13 can achieve the purpose of supporting the display screen 12.

Further, the outer surfaces of the pair of first mandrels 111 are respectively provided with a first plane 1112 along the axial direction thereof, and the inner surface of the first sleeve 1131 is provided with a second plane 1133 along the axial direction thereof;
