Description

rotating mechanism

The present invention relates to a rotating mechanism, and in particular to a rotating mechanism applied to a display device.

Most of the existing display devices are arranged horizontally. When the display device wants to display images, videos or documents in a vertical format, the display device arranged horizontally will generate an invalid area, which is not conducive to viewing. For this reason, a display device with a rotation function has been developed, which can adjust the display angle according to different display requirements. However, most of the existing TVs or display devices with rotation functions mainly rely on manual rotation, which is inconvenient and laborious to use.

The invention provides a rotating mechanism suitable for connecting to a display. The rotating mechanism can automatically turn to the display to adjust to a required viewing angle.

The rotating mechanism of the present invention is suitable for connecting to a display. The rotating mechanism includes a mounting base, a pivot module, a link assembly, a driving motor and a supporting base. The mounting base has a first side and a second side. The pivot module is rotatably arranged on On the first side of the mount, the display is connected to the pivot module. The connecting rod assembly is rotatably and slidably disposed on the mounting base. The drive motor is connected to the connecting rod assembly. The driving motor is fixed on the display. The support base is configured on the second side of the mounting base to cover the connecting rod assembly. An output shaft of the driving motor is adapted to rotate in a rotational direction to drive the connecting rod assembly to rotate and slide relative to the mounting base, thereby driving the display to reciprocate relative to the mounting base.

Based on the above, the rotating mechanism of the present invention is suitable for connecting a display. The rotating mechanism drives the link assembly to rotate and slide relative to the mounting base through the drive motor. At the same time, the link assembly drives the display to reciprocate relative to the mounting base, thereby adjusting the viewing angle of the display. Furthermore, the connecting rod assembly of the present invention is connected to the driving motor, so that the driving motor only needs to continuously rotate in a single rotation direction to achieve the effect of reciprocating rotation of the display, thereby simplifying the operating steps of the rotating mechanism. Therefore, the rotation mechanism of the present invention can achieve the purpose of automatically adjusting the display through the combination of the drive motor and the link assembly, thereby replacing the manual adjustment in the prior art.
