technical field

The present invention relates to a multi-directional support structure for a flat panel display device, especially a flat panel display device that can be adjusted to different tilt and flip angles, and can be combined with different functional chassis as required to meet different needs. support structure.

Background technique

The bracket or sheath structure commonly used in tablet computers is disclosed in the new patent case of Taiwan Patent Publication No. M411501 "Structure Improvement of Tablet Computer Support Frame". The support frame is mainly composed of a fixed plate body and a pivot joint The fixed plate body is composed of a bracket, and the fixed plate body is combined by a front cover and a rear cover, wherein a plurality of positioning parts extend in the direction of the front cover on the rear cover, and the rear cover is combined with a plurality of clamping plates, and each clamping plate Then, a guide groove corresponding to the sliding of the positioning member is formed, and the mutual restraint between the guide groove and the positioning member can effectively limit the position of the clamping plate. In addition, at the guide groove, a telescopic piece is set for the clamping plate to clamp against the tablet computer, so that each clamping plate can change the clamping range and achieve effective clamping for various tablet computers of different sizes through the telescopic piece. maintain a fixed effect. This structure only has the support effect of clamping the tablet computer and forming a fixed display angle, lacks variability in application, and cannot meet diverse usage requirements.

In addition, there is a new patent case of Taiwan Patent Announcement No. M414799 "Structure of supporting box frame for tablet computer", which mainly has a box body with a 100-leaf box cover, and the box body is a storage slot that can be inserted and combined with a Bluetooth wireless transmission keyboard , there is an interlayer in the lid, a bracket plate is pivoted on the base of the interlayer, and a support foot is pivoted behind the bracket plate; when the lid is unfolded and placed flat, the support foot supports the bracket plate to protrude at an inclination , to provide tablet placement, so that the tablet can be used on a table in response to the design of the tablet without a stand, and it conforms to a familiar operation pattern for those who are generally used to a physical keyboard. Although this kind of structure can make the tablet computer support with different fixed inclination angles, it is difficult to make the keyboard have an easy-to-operate inclination angle, and the tablet computer is not easy to operate and adjust to produce a horizontal display effect, and there are limitations in use .

China Taiwan Patent Announcement No. M414855 "Tablet PC Sheath" new patent case mainly includes a top cover and a base, a second turning portion is formed between the top cover and the base, so that the top cover and the base can be combined When folded, another first turning portion is formed near the middle of the base, so that the base can be bent at an angle. The upper cover is provided with magnets at several intervals. With the above-mentioned structural design, the base can be used for fixing the tablet computer on the On it, the tablet computer can be attracted by its existing iron core hidden in its periphery and the magnet of the upper cover, and cooperate with the bendable characteristics of the first and second bending parts, so that it can be used in different positions The magnets are attracted to each other, the tablet computer can be adjusted in more different viewing angles, and at the same time, the tablet computer can be protected to prevent the tablet computer from being scratched. This kind of structure basically also enables the tablet computer to be supported with different fixed inclination angles, but it cannot be combined with the keyboard, which is a change application of a sheath.

In view of the above-mentioned shortcomings in the application of the bracket or sheath structure of the common tablet computer, the inventors researched ways to improve these shortcomings, and finally came up with the present invention.
