Flat display remote control angle adjustment system

The invention relates to a remote viewing angle adjustment system applied to a flat panel display

Flat panel displays such as liquid crystal displays (LCDs) and plasma televisions have become increasingly popular and now dominate the market that used to be the traditional cathode ray tube (CRT). Because flat panels are thin in outline, they are often mounted on walls, brackets, or other vertically flat surfaces to save space. In order to obtain a better viewing angle, a flat panel display is often mounted on a support device that can be rotated to a desired angle. There are numerous patents in the art.

US 7,296,774 is a system for viewing angle adjustment that provides a support arm to connect the monitor to a surface such as a wall or ceiling to adjust the viewing angle of the monitor distally. The support arm includes at least one electric motor along the pivot axis in the support arm. The motor can be activated by a processor that receives control signals provided by the remote control. The support arm can include a plurality of pivot axes, wherein the motor is mounted on each of the pivot axes to adjust the viewing angle relative to the vertical and horizontal planes.

US 2007/0125917 A1 relates to an electric mounting system for repositioning a monitor that is capable of extending a monitor from a reference plane and tilting and rotating the monitor about the X, Y and Z axes. The electric mounting system includes a first pair of arms disposed between the bottom plate and the backing plate. The bottom plate is adapted to be attached to a wall and the backing plate is adapted to be attached to the back of the monitor. The first pair of arms includes two pivot arms that are symmetrical to each other. The proximal ends of the two pivot arms are pivotally connected to the base plate, and two The distal ends of the pivot arms are pivotally connected to the pad. At least one of the proximal ends of the first pair of arms can be engaged with the motor to rotate the distal end about its axis, which in turn extends or retracts the distal end of the first pair of arms. Another motor can be coupled to the distal end of the first pair of arms to rotate the monitor to the left and right. Yet another motor can be coupled to the distal end of the first pair of arms to tilt the monitor up and down.

The mechanisms disclosed in the above patents are generally in the form of links or arms. A connecting rod or arm has the advantage of being structurally simple, but is weak or too space-consuming when used to support an object having a large weight, especially when the connecting rod or arm needs to be rotatable. Further, as the display panel becomes larger and heavier, the support device formed by the link or the arm may be too weak in structure to securely support the display panel.

Furthermore, when adjusting the display angle, the center of gravity of the device as disclosed above will be displaced away from the wall or surface on which the device/display is mounted, and the displacement will apply additional stress to the support device, especially in progress When the translational movement is performed, the problem that the structure of the device is weak is more severe.
