The first screen is formed on the screen frame of the display screen installation belt, the first screen comprises a screen frame 200 formed by a plurality of fan-shaped frameworks 100, the fan-shaped frameworks 100 are provided with LED screens, and the first screen can be folded, and the folded structure of the first screen is not involved in the patent, so that the description is omitted.
The screen frame 200 comprises a bearing frame 201 and a rotating shaft 202, wherein the bearing frame 201 is provided with two rotating shafts 202, the sector-shaped framework 100 is arranged on the rotating shafts 202, the mounting bracket 400 is arranged on the bearing frame 201, and the second screen 300 is arranged on the mounting bracket 400. It is because the first screen is foldable, and if the LED screen is also installed near the center of the fan-shaped skeleton 100, there is a possibility that the skeleton may wear the LED screen. Therefore, the LED screen is not installed at the center of the first screen, the first screen of the folded portion is shielded by installing the second screen 300 at the center, and the picture is complete by overlapping the first screen and the second screen 300, so that the effect is better.
The whole foldable screen is hoisted on the top beam through a mounting bracket 400, the mounting bracket 400 comprises a bottom plate 401, a supporting column 402 and a supporting plate 403, the bottom plate 401 is mounted on the bearing frame 201, a sliding mechanism 404 is mounted on the bottom plate 401, and the supporting plate 403 is mounted on the sliding mechanism 404. In order to control more precisely, the sliding mechanism 404 may be a linear sliding table of a servo motor, and the type of the linear sliding table driven by the servo motor may be Z-Mod-SE-44, so long as the second screen 300 can be realized up and down. In order to prevent the second screen 300 from being lowered too much, a sensor bracket 413 is installed at the rear of the base plate 401, a third sensor 414 is installed on the sensor bracket 413, the second screen 300 is detected by the third sensor 414, and when the third sensor 414 cannot detect a signal during the lowering process, the linear sliding table of the servo motor stops moving, and similarly, the third sensor 414 may be installed at the top.
The rear part of the linear sliding table of the servo motor is provided with a back plate 405, the back plate 405 is connected with the support column 402 through a pull plate 406, and the bottom of the back plate 405 is connected with the bottom plate 401. Since the rotation shaft 202 is to be installed on the base plate 401, the width of the base plate 401 is relatively large, but the servo linear slide table needs to be installed at the forefront of the base plate 401 so that the up and down of the second screen 300 can be realized. The support column 402 is installed at the rear of the bottom plate 401, so in order to fix the linear sliding table of the servo motor, a first reinforcing plate 407 is arranged between the back plate 405 and the support column 402, and triangular second reinforcing plates 408 are arranged at two sides of the linear sliding table of the servo motor.
The entire foldable screen is also relatively heavy, and the cross section of the support plate 403 is U-shaped in order to reduce unnecessary weight, so that the weight of the support plate 403 can be reduced. The third connecting block 409 is installed to the lateral part of backup pad 403, and third connecting block 409 has first connecting plate 410 through bolted connection, and whole device is connected with the back timber mainly by first connecting plate 410, does not connect between first connecting plate 410 and the support column 402, conveniently adjusts holistic height. A second connection plate 411 is mounted at the rear of the support plate 403, and a bar-shaped adjustment hole 412 is provided on the second connection plate 411. The second connection plate 411 is fixed to the whole body in cooperation with the first connection plate 410.
The working process comprises the following steps: when the device is used, the winding shaft 501 rotates, the second connecting rope is loosened a little, the bottom fan-shaped framework is turned to the lower point, the top of the chute 126 of the lower fan-shaped framework is blocked by the limit bolt 124 of the upper fan-shaped framework, the fan-shaped framework moves in place, and the position of the fan-shaped framework at the top is controlled by the length of the first connecting rope. When the second detection sensors on the fan-shaped frameworks at the bottoms of the two sides detect signals, the second detection sensors indicate that the movement is in place, and the winding shaft 501 stops rotating. The second screen 200 is driven to descend by the sliding mechanism 404 until the third sensor 414 detects no signal, and the second screen 200 stops descending. When the whole screen is folded, the winding shaft 501 drives the second connecting ropes to be folded, the fan-shaped frameworks at the bottom move upwards, each fan-shaped framework moves upwards integrally after being contacted with the pull-up limiting block 130, and when the first detecting sensor 503 detects a signal, the winding shaft 501 stops rotating.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
