Background technique

Flat-panel monitors, such as LCD monitors, LCD TVs, or plasma TVs, etc., have gradually replaced traditional picture tube (CRT) monitors due to their advantages of light weight, thinness, and no radiation. In order to allow the flat monitor to stand, a connecting component is used to connect the flat monitor to a base on its back side, and a hinge is arranged between the connecting component and the flat monitor, so that the flat monitor has the ability to adjust the inclination angle. Function.

In order to provide a variety of viewing styles for flat-panel monitors, for example, the CN 1244852C patent "monitor with improved tilting structure" issued by China on March 8, 2006 (corresponding to U.S. Patent No. 6,822,857 as an example, The monitoring includes a monitor main body, a monitor bracket is fixedly arranged on its back, and a base hinge on the top of a base assembly is pivotally connected to the lower end of a connecting assembly, and the upper end of the connecting assembly has a main hinge, and the hinge Connected to a main bracket, the monitor bracket and the main bracket are pivotally connected with a pivot part, so that the monitor main body and the monitor bracket can be rotated in a plane on the main bracket by the pivot part. Since the monitor main body There is a height between the bottom edge and the base assembly, if the height is less than the distance from a corner of the bottom edge of the monitor body to the pivot member, then when the plane is rotated, the bottom edge corner of the monitor body will touch the desktop, and there is It may damage the main body of the monitor, and in order to improve this serious deficiency, the connecting component must have the function of height adjustment, so as to rotate in a plane, the height between the main body of the monitor and the base component must be adjusted to be greater than the bottom of the main body of the monitor The distance from the edge corner to the pivot part can make the monitor main body carry out plane rotation. However, as the size of the flat monitor becomes larger and larger, or the aspect ratio, such as the specification of 16:9, the bottom of the monitor main body The distance from the corner to the pivot member is greatly increased, which makes it difficult for the above-mentioned planar rotation mechanism to cope.

In fact, this patent uses a mobile phone as an example. When the plane rotates, the sliding member moves up along the main body and gradually tilts until it slides to a fixed position, so that the sliding member is arranged horizontally on the main body. Because this patent is not used for monitors, it does not need to consider the height between the monitor body and the base assembly, and when rotating and sliding, the sliding member first moves up and then rotates, and there is no translation stroke.
