[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0037] To address the technical problem of manually unfolding and stacking multiple screens sequentially during use, this invention provides a multi-screen communication command box that can flip up the main screen, automatically unfold the two side sub-screens, cover the main screen, and actively fold the sub-screens.

[0038] Please see Figure 1 , Figure 1 This is a three-dimensional view of the multi-screen communication command box in a second position according to an embodiment of the present invention. The multi-screen communication command box includes a box body 1, a main screen 2, a flexible pivot seat 3, a secondary screen 4, and a side panel 5. The main screen 2 is hinged to the top surface of the box body 1. Similar to a conventional multi-screen communication command box, the main screen 2 is flipped upwards for use and flipped downwards to close and store on top of the box body 1. There are two flexible pivot seats 3, which are respectively installed on the bottom sides of the main screen 2 and move with the main screen 2. Each flexible pivot seat 3 is provided with a rotating end 31, which is used to elastically push the corresponding rotating end 31 to rotate in a circle. There are two secondary screens 4, which are connected to the rotating end 31 one by one and have a first position that overlaps the back of the main screen 2. The main screen 2 has two positions: a first position (folded down) and a second position (expanded to one side). The first position is the storage position, and the second position is the usage position. Through the elastic push of the elastic pivot 3, when the main screen 2 is flipped upwards, the two secondary screens 4 automatically flip to the sides, stacking on the back of the main screen 2. When flipped to the sides, they rotate from back to front. That is, the elastic pivot 3 is not elastically compressed in the second position, but elastically compressed in the first position. There are two side rails 5, both fixedly connected to the housing 1 and positioned on either side of the main screen 2. When the main screen 2 rotates to fit against the top surface of the housing 1, they push the secondary screens 4 in the second position to rotate to a third position forming a 90-degree angle with the main screen 2. A cover 101 is hinged to the top of the housing 1 for covering the housing 1.

[0039] Understandably, the first position can be limited by the cover 101. When the cover 101 is opened, the secondary screen 4 can be switched from the first position to the third position by the elastic push of the elastic pivot 3. Then, the main screen 2 is flipped up, and the elastic pivot 3 continues to push, which will automatically switch to the second position, making it easier to unfold the secondary screen. In addition, when storing, both secondary screens 4 can be quickly stored to a 90-degree position by the side cover 5, which is convenient for subsequent folding.

[0040] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The number of secondary screens 4 is two, namely a first secondary screen 41 and a second secondary screen 42. The first secondary screen 41 and the second secondary screen 42 are respectively connected to the rotating ends 31 on the elastic rotating shaft seats 3 on both sides. In the first position state, the first secondary screen 41 and the second secondary screen 42 are stacked on the back of the main screen 2 one after the other, that is, the first secondary screen 41 is folded first and then the second secondary screen 42 is folded to form a three-fold storage.

[0041] For further details, please refer to Figure 1 , Figure 4 and Figure 5 In order to actively distinguish the order of stacking, the side panel 5 near the first sub-screen 41 is provided with an elastic telescopic pusher 6, which is used to push the first sub-screen 41 to stack on the back of the main screen 2 in the third position state, thereby distinguishing the sub-screen 4 that needs to be folded first, and forming the fold of the side sub-screen 4 when the main screen 2 is flipped down, simplifying the storage steps.

[0042] For further details, please refer to Figure 3 The elastic telescopic push seat 6 is provided with two latching protrusions 61. One latching protrusion 61 is used to push the first sub-screen 41 to overlap the back of the main screen 2 in the third position state. The other latching protrusion 61 is used to engage and position the second sub-screen 42 that overlaps the first sub-screen 41 in the first position state. Thus, in the first position state, both the first sub-screen 41 and the second sub-screen 42 are positioned, providing another layer of limiting in addition to the cover 101, making it more convenient to use. The main screen 2 will only switch to the third position state after the cover 101 is opened.

[0043] Understandably, during the downward folding process, the cam 61 is compressed first. When the main screen 2 rotates to below the cam 61 and the rotation axis between the first sub-screen 41 and the main screen 2 is below the cam 61, the cam 61 elastically pushes back, which can push the first sub-screen 41 to rotate in the folding direction.

[0044] In one embodiment, please refer to Figure 6 and Figure 7The elastic pivot seat 3 includes a linear cylinder 32, a first spring 33, a circumferential cylinder 34, and a circular slider 35. The rotating end 31 is rotatably connected inside the circumferential cylinder 34. The circumferential cylinder 34 has an annular cavity 3401 coaxial with it. The linear cylinder 32 is tangentially connected to the circumferential cylinder 34 and communicates with the annular cavity 3401. One end of the first spring 33 is connected to the inner wall of the linear cylinder 32, and the other end is connected to the circular slider 35, for elastically pushing the circular slider 35 to slide within the annular cavity 3401. A shaft 36 extends from the circular slider 35 and is rotatably connected to the rotating end 31. Figure 6 In the second position, both sub-screens 4 are in the unfolded state with the first spring 33 in its natural state, folded backward. The rotating end 31 rotates, driving the shaft 36 to make the circular slider 35 slide along the annular cavity 3401, compressing the first spring 33 and switching to the third position, as well as the first position. After losing the limiting position of the elastic telescopic push seat 6 with the locking protrusion 61, the first spring 33 elastically pushes back, switching to the third position. After losing the limiting position of the side block 5, the first spring 33 continues to elastically push back, switching to the second position.

[0045] Furthermore, in order to make the rotation slow and smooth, a friction layer is provided in the annular cavity 3401 to provide sliding damping for the circular slider 35 to slide along the annular cavity 3401.

[0046] In one embodiment, please refer to Figure 5 The elastic telescopic push seat 6 includes a second spring 62 and a block 63. A groove 501 is provided on the side block 5. One end of the second spring 62 is connected to the groove 501, and the other end is connected to the block 63. Both of the two latches 61 are fixedly connected to the block 63. During the movement, the latches 61 are pushed, causing the block 63 to slide along the groove 501, forming a telescopic movement. The upper and lower surfaces of the latches 61 are both inclined, so that when the edge of the sub-screen 4 is pushed against the latches 61, it has a component force that pushes towards the groove 501.

[0047] Furthermore, the second sub-screen 42 is provided with an extension plate 4201 on the side away from the main screen 2. When the extension plate 4201 is in the first position, it is engaged between the two protrusions 61 to form a second sub-screen 42 mounting position.

[0048] To better understand this utility model, the following is combined with... Figures 1 to 7The technical solution of this utility model is described in detail as follows: In the first position state, the screen is not unfolded. At this time, it is only necessary to flip the main screen 2 upward. Under the action of the elastic pivot seat 3, the two sub-screens 4 are gradually switched to the third position state. When the main screen 2 is fully flipped up, it switches to the second position state with the two sub-screens 4 unfolded. The entire screen unfolding process only requires one flipping action. The unfolding of the sub-screens 4 is automatically achieved during the flipping of the main screen 2. To store the folded screen, the main screen 2 is flipped downward. Under the pushing action of the side block 5, the two sub-screens 4 form a 90-degree angle with the main screen 2, forming a semi-folded storage. With the help of the elastic telescopic pushing seat 6, the first sub-screen 41 is pushed to fold. At this time, it is only necessary to manually fold the second sub-screen 42, which simplifies the folding and storage operation.

[0049] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
