Problems solved by technology

The maximum weight that can realize six-degree-of-freedom high-precision control is 15000N / m 2 , but the existing display screens that can realize six-degree-of-freedom movement are small in weight, so the maximum effective display area can only reach more than a dozen square meters. In long-distance viewing places such as grand theaters, the viewing effect is not good.
In addition, in the prior art, the large-screen LED display cannot achieve six degrees of freedom movement, let alone the combination of multiple screens to coordinate the movement

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0015] Depend on Figure 1 to Figure 3 ( image 3 A and B represent the states of the mechanical arms when the display is at two different points in the space), as shown in the above, the large-scale six-degree-of-freedom display screen coordination device includes three mechanical arms arranged in parallel at equal distances, and the structure of the three mechanical arms Similarly, each of the mechanical arms includes a column 2 , a stretching arm 5 , a first rotating arm 9 , a second rotating arm 11 and a third rotating arm 14 . specifically:

[0016] The column 2 is arranged vertically, and the upper bottom surface and the lower bottom surface of the column 2 are respectively provided with a column rotary motion pair 1 that rotates around the Y axis. The column rotary motion pair 1 is driven by a motor reducer, so that the column 2 can go ...

Abstract

The invention discloses a large-sized display screen coordinating device in six degrees of freedom. It comprises three identical mechanical arms disposed equidistantly and parallelly to one another. In each mechanical arm, a column (2) pivoting kinematic pair that can pivot about axis Y is provided respectively at the top and bottom ends of the vertically provided support column; one end of a tension arm (5) is provided on a side face of the vertical support column via a tension arm pivoting kinematic pair (4); a first pivoted arm (9) is fitted and connected to the free end of the tension arm via a first pivoting kinematic pair (8); a second pivoted arm (11) is fitted and connected to the free end of the first pivoted arm via a second pivoting kinematic pair (10); a third pivoted arm (14) is fitted and connected to the free end of the second pivoted arm via a third pivoting kinematic pair (12); and the third pivoted arm is fitted and connected to a display screen via a display screen pivoting kinematic pair (13).

Description

technical field [0001] The invention relates to a display screen coordination device, in particular to a large-scale six-degree-of-freedom display screen coordination device. Background technique [0002] At present, there is no large-screen, large-scale six-degree-of-freedom video display on the market, and three display screens can cooperate with each other with high precision at the same time, and complete various multi-difficulty combined actions. The maximum weight that can realize six-degree-of-freedom high-precision control is 15000N / m 2 , but the existing display screens that can realize six-degree-of-freedom motion are small in weight, so the maximum effective display area can only reach more than a dozen square meters. In places such as grand theaters and other long-distance viewing venues, the viewing effect is not good. In addition, in the prior art, large-screen LED display screens cannot achieve six-degree-of-freedom motion, let alone a combination of multiple...
