Description

TECHNICAL FIELD

[0001] The application is suitable for the technical field of mechanical design and electronic equipment integration, in particular to a new type of turnover structure of a display screen. BACKGROUND

[0002] The existing turnover screen is designed and produced by adopting the traditional back folding turnover mode when turning over. The back folding mode has the following problems: when the screen structure is single column and multi-row, that is, the number of rows is greater than or equal to 7 after the screen is completely unfolded, the number of each section is 2-3-2 when adopting A-B-C structure, the structure of turning over to the back of the screen can at most turn over once on the left and right sides respectively, and cannot turn over multiple times. When the single box screen is single column and multi-row and the number of rows is greater than or equal to 7, the size of the middle section B is greater than or equal to 3 after the screen is folded in a three-section structure, and the size after folding is relatively too long. When the single box screen is single column and multi-row and the number of rows is greater than or equal to 7, the size of the two side sections A and C is greater than or equal to 2 after the screen is folded in a three-section structure, and the size is relatively too high. As can be seen from the above, the traditional back folding hinge structure is limited by the "stacking backward" idea. The back folding mode of the traditional turnover screen faces the problems of limited turnover times, too large folding size and human-machine engineering defects in the application of single column and multi-row (≥7 rows) screen due to the single rotation design of "stacking backward". With the development of display technology towards large size and flexibility, it is urgent to develop a new type of turnover structure to break through the technical bottleneck of the existing technology and meet the needs of modern display devices for compact folding, convenient operation and reliable structure.

A fixed support shaft is installed between a pair of the mounting seats. A pair of rotating arms are installed on the fixed support shaft. A rotating arm shaft is installed at the other end of a pair of the rotating arms. A pair of butt joint mounting blocks are installed at both ends of the rotating arm shaft. A pair of the butt joint mounting blocks are connected with a pair of the moving auxiliary modules through a pair of large straight line guides.

[0004] Further provided in the application is that a pair of rotating limit blocks are installed on the rotating arm shaft and located at the rotating position of the rotating arm.

[0005] Further provided in the application is that the contact part of the rotating limit block and the rotating arm is in the form of arc and plane combination.

[0006] The docking mounting block is provided with two docking channels, the two docking channels are opposite and perpendicular to each other, one of the two docking channels is matched with the rotating arm rotating shaft, and the other of the two docking channels is matched with the large linear guide rail.

[0007] The lower wall surface of the turnover body is further provided with a pair of movable docking modules, and the pair of movable docking modules are connected with the pair of mounting seats through a pair of movable front-end linear guide rails.

[0008] The rotating arm is in a special U-shaped structure, the contact part of the rotating arm and the rotating limiting block is also in a combined form of an arc and a plane, the end of the rotating arm close to the rotating limiting block is perpendicular to the middle part of the rotating arm, and the other end close to the mounting seat is in an arc structure with the middle part of the rotating arm.

[0009] The present application has the beneficial technical effects that the present application is specially designed to solve the problems, and the screen can be separated from the splicing and turned forward after being turned over, and the screen after being turned over can be used in combination with a backward turning hinge. Therefore, the folding effect can be achieved unlimitedly (usually three to four times, and theoretically unlimitedly), and the number of rows of the screen after being folded is not limited by the overall height, so that the folding frequency limitation, size out of control and man-machine engineering defects of the traditional backward turning structure are fundamentally solved.

[0014] The present application is composed of a plane body 1 (fixed display unit), a turnover body 2 (movable display unit) and a turnover structure 3 (core transmission system), which realizes the controllable forward rotation and folding of two display screens. It is different from the one-way stacking logic of the traditional rear turnover structure, that is, the controllable rotary motion of the turnover body 2 relative to the plane body 1 is realized through a plurality of mechanical connecting members. The turnover structure 3 as the core transmission component integrates the shaft, rotating arm, guide rail and limiting device, The overall turnover structure mainly includes a fixed support shaft part, a large swing arm and shaft part, a swing arm shaft part and a forward butt joint part, wherein: Fixed support pivot part: composed of mounting seat 4 and fixed support pivot 5, the fixed support pivot part is a primary reference component of the turnover structure 3, and is the cornerstone of the entire transmission system, and the technical boundary is clearly defined as: through the rigid coupling of the mounting seat 4 and the fixed support pivot 5, the fixed rotation axis of the rotating arm 6 is constructed.
