Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The embodiment of the application provides a display device, which may be a television, a computer display, an advertisement player, a conference board, or the like, and the embodiment of the application is not limited thereto.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present disclosure. The display device may include a base 100, a first driving part 200, a supporter 300, a second driving part 400, a connector 500, and a display screen 600.

The first driving part 200 is disposed at the base 100. The supporter 300 is rotatably installed to the base 100. The support 300 is in driving connection with the first driving part 200 to be driven by the first driving part 200 to rotate around the first axis. The second driving part 400 is disposed on the supporter 300. The connection member 500 is rotatably mounted to the supporter 300. The connection member 500 is in driving connection with the second driving part 400 to be driven by the second driving part 400 to rotate along a second axis, and the second axis is perpendicular to the first axis. The display screen 600 is fixedly connected with the connector 500.

In the actual use process, the first axis may extend in the vertical direction, and the second axis may extend in the horizontal direction, so that the display screen 600 may be driven to rotate left and right by the first driving component 200, and the display screen 600 may be driven to rotate back and forth by the second driving component 400. Thus, according to the actual position of the user, the first driving part 200 and the second driving part 400 can adjust the orientation of the display screen 600, so that the normal line of the display screen 600 can be oriented to the user, and the viewing experience of the user is improved.

Of course, the first axis may extend in a horizontal direction, and the second axis may extend in a vertical direction, which is not limited in the embodiment of the present application.

In actual use, the display device may be placed on a support surface such as a television cabinet via the base 100.

With continued reference to fig. 2, fig. 2 is a schematic diagram illustrating an assembly of parts of the display device shown in fig. 1. Optionally, the display device may also be hung from a wall. For example, the base 100 is further connected to a bracket 11, and the bracket 11 is used for hanging to a wall. Then, the user can put the display device on the television cabinet through the base 100 according to the actual practical use requirement, or hang the display device on the wall through the bracket 11, so as to improve the use experience of the user.

Specifically, the bracket 11 may be directly screwed and fixed to the wall; for example, the bracket 11 is provided with a plurality of screw holes, so that the bracket 11 can be directly locked and fixed to the wall body by expansion screws or the like.

Alternatively, the bracket 11 may be fixed to the wall by a display hanger hung on the wall. For example, the bracket 11 is provided with a first clamping structure and a first screw structure, and the display device hanging frame is provided with a second clamping structure and a second screw structure. The first clamping structure and the second clamping structure are clamped, so that the support 11 and the display device hanging frame are preliminarily fixed. The first screw structure and the second screw structure are screw-fixed, thereby realizing the locking of the bracket 11 and the display device hanging frame.

The bracket 11 may be integrally formed with the base 100, thereby enhancing the strength of the connection of the bracket 11 with the base 100 to prevent the display screen 600 from falling off during use.

The bracket 11 may be formed separately from the base 100. For example, the stand 11 may be detachably connected to the base 100, so that the stand 11 may be removed when a user wants to directly place the display device in a television cabinet. In addition, according to the size change of the display screen 600, the bracket 11 with different sizes can be selected to be connected with the base 100, so that more reliable installation of the display screen 600 is improved.

In some embodiments, the stand 11 may be slidably connected to the base 100, and the display device further includes a third driving part (not shown) for driving the base 100 to slide along a third axis. The third axis is parallel to the horizontal direction and perpendicular to the first axis.

It will be appreciated that the display 600 is typically wall-mounted during actual use. The angle at which the first driving part 200 drives the display screen 600 to rotate left and right is limited, and the angle between the user and the normal line of the display screen 600, mainly in the left and right direction, may be large. Then, when the user is positioned at the left or right side of the display screen 600, the base 100 may be driven to move left or right by a certain distance as a whole by the third driving part, and then the display screen 600 may be driven to rotate left or right by the first driving part 200.

The foregoing is illustrative of some of the base 100 embodiments of the present application, and the following description is illustrative of some of the alternative configurations of the support 300.

The supporter 300 may be provided with a first tooth portion 313. The first tooth 313 meshes with the first drive member 200 to form a drive connection.

It will be appreciated that as the display screen 600 progresses toward larger screens, the weight of the display screen 600 increases. Therefore, the bearing member 300 and the first driving member 200 are driven by means of gear engagement, so that the advantages of large bearing force and high transmission efficiency of the gear transmission can be fully utilized to adjust the angle of the display screen 600, and the gear transmission mode can also enable the display device to have the advantage of high adjustment precision.

The first driving part 200 may include a first motor 21 and a first worm 22, for example. The first motor 21 is fixedly disposed on the base 100. The first worm 22 is fixedly connected with the output shaft of the first motor 21, and the first worm 22 is also meshed with the first tooth portion 313. Thus, the first motor 21 may drive the supporter 300 to rotate through the first worm 22.

Alternatively, the first driving part 200 may further include a first motor 21 and a first gear shaft. The first motor 21 is fixedly disposed on the base 100. The first gear shaft is fixedly connected with the output shaft of the first motor 21, and the first gear shaft is also meshed with the first tooth portion 313. Accordingly, the first motor 21 may rotate the supporter 300 through the first gear shaft, which is not limited in the embodiment of the present application.

The first motor 21 may be a stepper motor or a servo motor, which is not limited in the embodiment of the present application.

In some embodiments, the supporter 300 may include a cross plate 31, a riser 32, and a first rotation shaft 33.

The cross plate 31 includes a transmission portion 311 and a connection portion 312 connected. The transmission part 311 is in a sector shape, the axial lead of the transmission part 311 is overlapped with the first axial lead, and the first tooth part 313 is arranged on the outer periphery side of the transmission part 311 in a surrounding way. Thus, after the first driving member 200 is engaged with the first teeth 313, the supporter 300 may be driven to rotate about the first axis direction.

The standing plate 32 is vertically connected to the connection portion 312. The first rotating shaft 33 is fixedly connected with the vertical plate 32. The axis of the first rotating shaft 33 coincides with the second axis, and the connection member 500 is rotatably mounted to the first rotating shaft 33, so that the connection member 500 and the display screen 600 mounted on the connection member 500 can rotate around the second axis.

In some embodiments, the riser 32 may comprise two, with the two risers 32 disposed opposite. Each end of the first rotation shaft 33 is fixedly connected to one of the vertical plates 32, respectively, so that the connection member 500 and the display screen 600 mounted on the connection member 500 can be rotated about the second axis.

In some embodiments, the retainer 300 may also be provided with a first end bearing (not shown). The first end bearing is sandwiched between the riser 32 and the connector 500. Thus, the first end bearing can make the connection member 500 and the display screen 600 mounted on the connection member 500 more stable and reliable.

Specifically, the first end bearing may be sleeved on the first shaft 33.

In some embodiments, the base 100 may be provided with a second rotation shaft 12, the second rotation shaft 12 coinciding with the first axis, and the supporter 300, such as the transverse plate 31 of the supporter 300, is rotatably disposed on the second rotation shaft 12. Thereby enabling the support 300 to be rotatably mounted on the base 100 about a first axis.

In some embodiments, the base 100 may be provided with a second end bearing (not shown). The second end bearing abuts against the supporter 300, such as the cross plate 31 of the supporter 300, to provide support to the supporter 300, thereby making the supporter 300 and the connection member 500 and the display 600 provided on the supporter 300 more stably and reliably installed.

Specifically, the second end bearing may be sleeved on the second rotating shaft 12.

The foregoing is illustrative of some of the support members 300 of the present embodiments, and the following description is directed to alternative configurations of the connector 500.

In some embodiments, the connection 500 is provided with a second tooth 51, the second tooth 51 being engaged with the second drive member 400 to form a transmission connection.

It will be appreciated that as the display screen 600 progresses toward larger screens, the weight of the display screen 600 increases. Therefore, the connection piece 500 and the second driving component 400 are driven by means of gear engagement, so that the advantages of large bearing capacity and high transmission efficiency of the gear transmission can be fully utilized to adjust the angle of the display screen 600, and the gear transmission mode can also enable the display device to have the advantage of high adjustment precision.

The second driving part 400 may include a second motor 41 and a second worm 42, for example. The second motor 41 is fixedly provided to the supporter 300 such as the cross plate 31 of the supporter 300. The second worm 42 is fixedly connected to the output shaft of the second motor 41, and the second worm 42 is further meshed with the second tooth portion 51. Thus, the second motor 41 may drive the connection 500 to rotate through the second worm 42.

Alternatively, the second driving part 400 may further include a second motor 41 and a second gear shaft. The second motor 41 is fixedly disposed on the supporter 300. The second gear shaft is fixedly connected to the output shaft of the second motor 41, and the second gear shaft is also meshed with the second tooth portion 51. Accordingly, the second motor 41 may rotate through the second gear shaft driving connection 500, which is not limited in the embodiment of the present application.

Specifically, the second motor 41 may be a stepper motor or a servo motor, which is not limited in the embodiment of the present application.
