[0002] Currently, electronic devices such as mobile phones, tablet computers, desktop computers, televisions, cash registers, etc. all require the use of display screens.

[0003] However, in the prior art, most display screens of computers do not have the function of splicing screens. The rotation of the display screen is realized through a hinge structure with a single rotating shaft. For a computer with dual-screen display, it is impossible to splice the main screen and the secondary screen on the same hinge structure by adjusting the support. Therefore, it cannot meet the usage requirements in different scenarios and limits the application range of the display screen.

[0093] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts fall within the protection scope of the present invention.

[0094] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0095] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0096] As Figure 1 and Figure 2 shown, this embodiment provides a rotating split-screen bracket mechanism, which includes a fixed bracket 1, a first bracket 2, a second bracket 3, a flipping assembly 4, and a rotating bracket 5.

[0097] Among them, the first bracket 2 is used to connect with the first display screen 100, and the second bracket 3 is used to connect with the second display screen 200. One end of the flipping assembly 4 is rotatably connected to the first bracket 2 around the first axis, and the other end of the flipping assembly 4 is rotatably connected to the second bracket 3 around the first axis. Both the first bracket 2 and the second bracket 3 can rotate relative to the flipping assembly 4 to a preset angle so that the first display screen 100 and the second display screen 200 can be split-screened or combined. The rotating bracket 5 is rotatably connected to the flipping assembly 4 around the first axis, and the rotating bracket 5 is rotatably connected to the fixed bracket 1 around the second axis, so that after the first display screen 100 and the second display screen 200 are combined, they can be switched between the landscape screen state and the portrait screen state, and the first axis is perpendicular to the second axis.

[0098] In this embodiment, the first axis extends along Figure 1 the direction parallel to the first display screen 100 (the second display screen 200), and the second axis extends along Figure 1 the direction perpendicular to the first display screen 100 (the second display screen 200).

[0099] The rotating split-screen support mechanism provided in this embodiment enables the first display screen 100 and the second display screen 200 to be used separately. By adjusting the rotation angles of the first support 2 and the second support 3 relative to the flipping assembly 4, the first display screen 100 and the second display screen 200 can be disposed on both sides of the fixed frame 1 for two people to operate. When the first display screen 100 and the second display screen 200 need to be used for split-screen, by adjusting the rotation angles of the first support 2 and the second support 3 relative to the flipping assembly 4, the three can be rotated to the same plane so that the first display screen 100 and the second display screen 200 are spliced and used as a large display screen. In addition, by adjusting the rotation angle of the rotating support 5 around the second axis, the first display screen 100 and the second display screen 200 after split-screen can be displayed horizontally or vertically to meet different usage requirements. That is, the rotating split-screen support mechanism can not only enable the first display screen 100 and the second display screen 200 to be used separately, but also enable the first display screen 100 and the second display screen 200 to be used for split-screen, and at the same time can switch between horizontal and vertical screens, which is applicable to a variety of usage scenarios, has a wide application range, and can effectively save the input cost of the display screen.

[0100] Optionally, referring to Figure 1 and Figure 2 , the fixed frame 1 includes a base 11 and a mounting housing 12 provided on the base 11. An installation cavity 121 (as shown in Figure 11 ) is provided in the mounting housing 12 for accommodating the host computer. That is, the first display screen 100 and the second display screen 200 can share a plug-and-play host computer, saving the usage cost. Moreover, placing the host computer in the installation cavity 121 saves floor space and is convenient to use.

[0101] Furthermore, a rubber gasket is provided at the bottom of the base 11, and the rubber gasket can increase the friction between the base and the desktop or the ground so that the base 11 can be stably placed on a bearing platform such as a desktop or the ground.

[0102] Optionally, referring to Figure 2 , the rotating split-screen support mechanism further includes a first rotating assembly 6 and a second rotating assembly 7. The first support 2 is rotatably connected to the first display screen 100 through the first rotating assembly 6, and the second support 3 is rotatably connected to the second display screen 200 through the second rotating assembly 7. By providing the first rotating assembly 6 and the second rotating assembly 7, the angle between the first display screen 100 and the first support 2 can be adjusted, and the angle between the second display screen 200 and the second support 3 can also be adjusted, so that the display angle, display height of the first display screen 100 and the second display screen 200, and the distance from the fixed frame 1 can be adjusted to meet the usage requirements of different users.

[0103] As shown in Figure 14As shown, at this time, the first bracket 2 is parallel to the first display screen 100, the second bracket 3 is parallel to the second display screen 200, and the first display screen 100 and the second display screen 200 are closely attached to the installation housing 12, and it can be used in the case of a small installation space. As Figure 15 shown, at this time, the angles between the first bracket 2 and the first display screen 100 and between the second bracket 3 and the second display screen 200 are both acute angles. The first display screen 100 and the second display screen 200 both maintain a certain distance from the installation housing 12, and the heights of the first display screen 100 and the second display screen 200 are raised, which can meet the needs of users of different heights. As Figure 16 shown, at this time, the first bracket 2 is perpendicular to the first display screen 100, the second bracket 3 is perpendicular to the second display screen 200, the display heights of the two display screens reach the highest, and the distances from the installation housing 12 reach the farthest. As Figure 17 shown, at this time, the angle between the first bracket 2 and the first display screen 100 is adjusted to 0 degree again, the angle between the second bracket 3 and the second display screen 200 is also 0 degree, the first bracket 2, the second bracket 3 and the flipping assembly 4 are in the same plane, and the first display screen 100 and the second display screen 200 are docked.

[0104] Optionally, referring to Figure 3 and Figure 4 , both the first rotating assembly 6 and the second rotating assembly 7 include a rotating seat 61 and a first rotating shaft 62. The rotating seat 61 is fixed on the first display screen 100 or the second display screen 200, and a first rotating hole 611 is provided on the rotating seat 61. The first rotating shaft 62 is arranged at one end of the first bracket 2 or the second bracket 3 away from the flipping assembly 4. The first rotating shaft 62 can penetrate into the first rotating hole 611 and is rotationally matched with the first rotating hole 611 within a first preset angle range. That is, the structures of the first rotating assembly 6 and the second rotating assembly 7 are the same. The rotating seat 61 of the first rotating assembly 6 is fixed on the first display screen 100, the rotating seat 61 of the second rotating assembly 7 is fixed on the second display screen 200, the first rotating shaft 62 of the first rotating assembly 6 is arranged on the first bracket 2, and the first rotating shaft 62 of the second rotating assembly 7 is arranged on the second bracket 3. The rotational connection between the first display screen 100 and the first bracket 2 and the rotational connection between the second display screen 200 and the second bracket 3 are realized through the rotational cooperation between the first rotating shaft 61 and the first rotating hole 611.

[0105] Optionally, referring to Figure 4, a first arc-shaped notch 621 is provided on the first rotating shaft 62, and a first limiting protrusion 612 is provided on the rotating seat 61 at the first rotating hole 611. When the first rotating shaft 62 rotates in the first rotating hole 611, the first limiting protrusion 612 can move in the first arc-shaped notch 621 to limit the rotation of the first rotating shaft 62 within a first preset angle range. That is, the angle range within which the first limiting protrusion 612 can move in the first arc-shaped notch 621 is the first preset angle range, and the first rotating shaft 62 can only rotate within the first preset angle range to limit the angle between the first display screen 100 and the first bracket 2 and the angle between the second display screen 200 and the second bracket 3, ensuring that the first bracket 2 and the second bracket 3 can stably support the first display screen 100 and the second display screen 200 within the first preset angle range.

[0106] Exemplarily, the range of the first preset angle is from 0 degree to 90 degrees. Between the first display screen 100 and the first bracket 2 and between the second display screen 200 and the second bracket 3, they can stay at any angle between 0 degree and 90 degrees.

[0107] Specifically, when driving the first display screen 100 or the second display screen 200 to move, it drives the rotating seat 61 to move, and then makes the first rotating shaft 62 rotate relative to the first rotating hole 611. During the rotation process, a frictional force will be generated between the first rotating shaft 62 and the hole wall of the first rotating hole 611, so that the first display screen 100 and the second display screen 200 can stay at any angle. Additionally, taking the first rotating assembly 6 as an example, refer to Figure 4 , the hole wall of the first rotating hole 611 has a plane. Correspondingly, a plane is also provided on the first rotating shaft 62, as Figure 14 and Figure 17 shown. When the angle between the first display screen 100 and the first bracket 2 is 0 degree (the first bracket 2 is parallel to the first display screen 100), the plane of the first rotating hole 611 fits with the plane on the first rotating shaft 62, making the first bracket 2 and the first display screen 100 automatically close, saving floor space. When the first display screen 100 rotates 90 degrees relative to the first bracket 2, the first limiting protrusion 612 is engaged with the first arc-shaped notch 621 to achieve limiting (as Figure 16 shown).

[0108] Preferably, refer to Figure 4 , the rotating seat 61 is an L-shaped plate structure. One of the plates of the L-shaped plate is used to be connected and fixed to the first display screen 100 or the second display screen 200 (in this embodiment, this plate is embedded in the screen frame at the rear side of the display screen), and the other plate of the L-shaped plate curls inward to form the above-mentioned first rotating hole 611.

[0109] Further, refer to Figure 3, both the first rotating assembly 6 and the second rotating assembly 7 further include a protective housing 63. The protective housing 63 is snap-connected to the screen frame on the rear side of the first display screen 100 or the second display screen 200, and covers the exposed parts of the first rotating shaft 62 and the rotating seat 61 to protect the rotating connection between the first rotating shaft 62 and the first rotating hole 611, preventing foreign objects from entering and affecting rotation. At the same time, it can make the outside of the first display screen 100 and the second display screen 200 neat and beautiful.

[0110] In this embodiment, two first rotating assemblies 6 and two second rotating assemblies 7 are provided to improve the rotational stability of the first display screen 100 relative to the first bracket 2 and the rotational stability of the second display screen 200 relative to the second bracket 3.

[0111] Optionally, referring to Figure 5 , Figure 6 and Figure 7 , the flipping assembly 4 includes a first flipping structure 41 and a second flipping structure 42. Both the first flipping structure 41 and the second flipping structure 42 include a first connecting shaft 411, a second connecting shaft 412, and a first locking assembly 413. The first connecting shaft 411 extends along the first axis, and the first connecting shaft 411 is connected to the first bracket 2. The second connecting shaft 412 extends along the first axis, and the second connecting shaft 412 is connected to the rotating bracket 5. The first connecting shaft 411 passes through and is rotatably connected to one end of the first locking assembly 413, and the second connecting shaft 412 passes through and is rotatably connected to the other end of the first locking assembly 413. The first locking assembly 413 can limit the rotation of the first connecting shaft 411 around the first axis within a second preset angle range, and the first locking assembly 413 can limit the rotation of the second connecting shaft 412 around the first axis within a third preset angle range.

[0112] By providing the first flipping structure 41 and the second flipping structure 42, the angle between the first bracket 2 and the flipping assembly 4 can be adjusted within a certain angle range, and the angle between the rotating bracket 5 and the flipping assembly 4 can also be adjusted within a certain range. Thus, the relative positions of the first bracket 2, the rotating bracket 5, and the flipping assembly 4 can be adjusted to make the first display screen 100 and the second display screen 200 in a split-screen or combined-screen state. As Figure 18 shown, at this time, the first bracket 2 and the second bracket 3 are respectively located on both sides of the installation housing 12, the flipping assembly 4 is located above the installation housing 12, and the first display screen 100 and the second display screen 200 are located on both sides of the installation housing 12. As Figure 21 shown, at this time, the first bracket 2 is flipped 90 degrees counterclockwise and is in the same plane as the flipping assembly 4, and the first display screen 100 is perpendicular to the installation housing 12. As Figure 24As shown, at this time, the flipping component 4 and the first bracket 2 are simultaneously flipped counterclockwise by 90 degrees. The first bracket 2, the flipping component 4, and the second bracket 3 are located in the same vertical plane. The first display screen 100 and the second display screen 200 are spliced and in a vertical screen state.

[0113] In this embodiment, referring to Figure 2 and Figure 5 , the first connecting shaft 411 is fixedly connected to the first bracket 2, the second connecting shaft 412 is fixedly connected to the rotating bracket 5, and the rotating bracket 5 can only rotate relative to the fixed frame 1 around the second axis. When the first bracket 2 is driven by the first display screen 100 to rotate relative to the flipping component 4, the first bracket 2 drives the first connecting shaft 411 to rotate relative to the first locking component 413. When the first bracket 2 rotates relative to the flipping component 4 to the first preset angle, the first connecting shaft 411 is locked by the first locking component 413, and the first bracket 2 can no longer rotate relative to the flipping component 4. Similarly, when the flipping component 4 rotates relative to the rotating bracket 5, since the second connecting shaft 412 is fixed to the rotating bracket 5 and the second connecting shaft 412 does not move, the first locking component 413 will rotate relative to the second connecting shaft 412 with the flipping component 4. When the second connecting shaft 412 and the first locking component 413 rotate relative to each other to the second preset angle, the second connecting shaft 412 and the first locking component 413 are locked, and the flipping component 4 and the rotating bracket 5 can no longer rotate relative to each other.

[0114] Optionally, referring to Figure 6 and Figure 7 , the first locking component 413 includes a first limiting plate 4131, a second limiting plate 4132, a limiting sliding plate 4133, a first card 4134, and a second card 4135. The first connecting shaft 411 sequentially passes through one end of the first limiting plate 4131, the first card 4134, and one end of the second limiting plate 4132, and the second connecting shaft 412 sequentially passes through the other end of the first limiting plate 4131, the second card 4135, and the other end of the second limiting plate 4132. Among them, both ends of the first limiting plate 4131 and the second limiting plate 4132 are respectively rotatably connected to the first connecting shaft 411 and the second connecting shaft 412. The limiting sliding plate 4133 is located between the first limiting plate 4131 and the second limiting plate 4132 and can slide along the extending direction of the first limiting plate 4131. The first card 4134 is fixed to the first connecting shaft 411, and a first notch 41341 is provided on the first card 4134. The second card 4135 is fixed to the second connecting shaft 412, and a second notch 41351 is provided on the second card 4135. The limiting sliding plate 4133 can switch between a first position where it is engaged with the first notch 41341 and a second position where it is engaged with the second notch 41351 to lock the rotation of the first connecting shaft 411 or lock the rotation of the second connecting shaft 412.

[0115] AsFigure 18 and Figure 19 As shown in Figure 19 , the first display screen 100 and the second display screen 200 are respectively located on opposite sides of the fixing frame 1. At this time, the left end of the limit slide plate 4133 faces the second notch 41351 of the second card 4135, and the right end of the limit slide plate 4133 abuts against the outer edge of the first card 4134. When the first display screen 100 is adjusted from the state of Figure 18 to the state of Figure 21 , the first bracket 2 rotates counterclockwise relative to the flipping assembly 4, so that the first connecting shaft 411 drives the first card 4134 to rotate counterclockwise around the first axis. During this process, the outer edge of the first card 4134 will squeeze and push the limit slide plate 4133 to slide to the left, so that the limit slide plate 4133 is clamped with the first notch 41341 (as shown in Figure 22 ), thereby restricting the rotation of the second connecting shaft 412.

[0116] When the first display screen 100 is adjusted from the state of Figure 21 to the state of Figure 24 , the flipping assembly 4 rotates counterclockwise relative to the rotating bracket 5 and the second bracket 3. During this process, the first limiting plate 4131 and the second limiting plate 4132 drive the limit slide plate 4133 to rotate relative to the second connecting shaft 412. Since the second card 4135 is fixed to the second connecting shaft 412, the limit slide plate 4133 will slide to the right in Figure 22 under the action of the extrusion force on the outer edge of the second card 4135, so that the limit slide plate 4133 is clamped with the first notch 41341 of the first card 4134 (as shown in Figure 25 ), thereby restricting the rotation of the first connecting shaft 411. That is, when adjusting the positional relationship among the first bracket 2, the flipping assembly 4 and the rotating bracket 5 (the second bracket 3), only one of the first connecting shaft 411 and the second connecting shaft 412 can rotate, so as to ensure the support stability of the first display screen 100 and the second display screen 200 after screen splicing and splitting.

[0117] It can be understood that by rotating the first display screen 100 in the reverse direction from the state of Figure 24 , the flipping assembly 4, the first bracket 2 and the first display screen 100 can be sequentially switched to the states of Figure 21 and Figure 18 , changing from using the screen in a spliced manner to using the screen in a split manner, meeting the usage requirements in different scenarios.

[0118] Optionally, referring to Figure 7, on the first limiting plate 4131 and the second limiting plate 4132, strip-shaped holes 41321 are arranged along their length directions. On the opposite sides of the limiting sliding plate 4133, convex strips 41331 are arranged. The length of the convex strips 41331 is less than the length of the strip-shaped holes 41321. The two convex strips 41331 are correspondingly clamped into the two strip-shaped holes 41321 and can be slidably matched with the strip-shaped holes 41321. When the first connecting shaft 411 or the second connecting shaft 412 rotates, the limiting sliding plate 4133 can slide between the first card 4134 and the second card 4135 through the sliding match between the convex strips 41331 and the strip-shaped holes 41321, so that the limiting sliding plate 4133 is clamped with the first card 4134 or clamped with the second card 4135, thereby restricting the rotation of the first connecting shaft 411 or the second connecting shaft 412. At the same time, the cooperation between the strip-shaped holes 41321 and the convex strips 41331 can also prevent the limiting sliding plate 4133 from detaching from the first limiting plate 4131 and the second limiting plate 4132, ensuring that the limiting sliding plate 4133 slides between the first limiting plate 4131 and the second limiting plate 4132 along the preset direction.

[0119] Refer to Figure 6 and Figure 7 , optionally, the first locking assembly 413 further includes a first limiting piece 4136, a second limiting piece 4137, a first stopping piece 4138 and a second stopping piece 4139. The first limiting piece 4136 is fixed to the first connecting shaft 411 and abuts against the first limiting plate 4131. The second limiting piece 4137 is fixed to the second connecting shaft 412 and abuts against the first limiting plate 4131. The first stopping piece 4138 is fixed to the first connecting shaft 411 and abuts against the second limiting plate 4132. The second stopping piece 4139 is fixed to the second connecting shaft 412 and abuts against the second limiting plate 4132. The first stopping piece 4138 is used to limit the first limiting piece 4136, one end of the first limiting plate 4131, the first card 4134 and one end of the second limiting plate 4132 on the first connecting shaft 411. The second stopping piece 4139 is used to limit the second limiting piece 4137, the other end of the first limiting plate 4131, the second card 4135 and the other end of the second limiting plate 4132 on the second connecting shaft 412.

[0120] Preferably, both the first stopping piece 4138 and the second stopping piece 4139 include a first nut and a first pressing gasket. External threads are arranged at the ends of the first connecting shaft 411 and the second connecting shaft 412. When assembling the first flipping structure 41 and the second flipping structure 42, the first pressing gasket is sleeved on the first connecting shaft 411 (the second connecting shaft 412), and then the first nut is screwed onto the first connecting shaft 411 (the second connecting shaft 412) through the external thread.

[0121] Further, both the first connecting shaft 411 and the second connecting shaft 412 are square shafts. Square holes are provided on the first card 4134, the second card 4135, the first limiting piece 4136, and the second limiting piece 4137. The cooperation between the square holes and the square shafts fixes both the first card 4134 and the first limiting piece 4136 to the first connecting shaft 411, and fixes both the second card 4135 and the second limiting piece 4137 to the second connecting shaft 412, thus ensuring that the first card 4134 and the first limiting piece 4136 cannot rotate relative to the first connecting shaft 411, and the second card 4135 and the second limiting piece 4137 cannot rotate relative to the second connecting shaft 412.

[0122] Optionally, referring to Figure 7 , a second arc-shaped notch 41361 is circumferentially provided on the first limiting piece 4136, and a third arc-shaped notch 41371 is circumferentially provided on the second limiting piece 4137. Referring to Figure 6 , two ends of the first limiting plate 4131 are respectively provided with a second limiting protrusion 41311 and a third limiting protrusion 41312. When the first connecting shaft 411 rotates relative to the first limiting plate 4131, the second limiting protrusion 41311 moves within the second arc-shaped notch 41361, so that the first connecting shaft 411 rotates within a second preset angle range. When the second connecting shaft 412 rotates relative to the first limiting plate 4131, the third limiting protrusion 41312 rotates within the third arc-shaped notch 41371, so that the second connecting shaft 412 rotates within a third preset angle range.

[0123] As Figure 18 and Figure 20 shown, the first display screen 100 and the second display screen 200 are respectively located on opposite sides of the fixing frame 1. The lower end of the second arc-shaped notch 41361 of the first limiting piece 4136 is clamped with the second limiting protrusion 41311, and the lower end of the third arc-shaped notch 41371 of the second limiting piece 4137 is clamped with the third limiting protrusion 41312. During the process of the first display screen 100 being adjusted from the state of Figure 18 to the state of Figure 21 , the first bracket 2 drives the first connecting shaft 411 to rotate counterclockwise relative to the first limiting plate 4131 and the second limiting plate 4132. At the same time, the second limiting protrusion 41311 moves within the second arc-shaped notch 41361 until the second limiting protrusion 41311 is clamped with the upper end of the second arc-shaped notch 41361 (as shown in Figure 23 ), and at this time, the first bracket 2 rotates to the second preset angle.

[0124] During the process of the first display screen 100 being adjusted from the state of Figure 21 to Figure 24During the process of the state, the first limiting plate 4131 and the second limiting plate 4132 rotate counterclockwise relative to the second connecting shaft 412. At the same time, the third limiting protrusion 41312 moves within the third arc-shaped notch 41371 until the third limiting protrusion 41312 engages with the upper end of the third arc-shaped notch 41371 (as Figure 26 shown), at this time, the flipping assembly 4 rotates relative to the rotating bracket 5 to a third preset angle.

[0125] Optionally, referring to Figure 2 and Figure 3 , the flipping assembly 4 further includes a first housing 43 and a second housing 44 which are buckled and connected. The first housing 43 and the second housing 44 enclose a receiving cavity, and both the first flipping structure 41 and the second flipping structure 42 are located within the receiving cavity. The arrangement of the first housing 43 and the second housing 44 can wrap the first flipping structure 41 and the second flipping structure 42 within the receiving cavity, ensuring a neat and beautiful exterior. In this embodiment, referring to Figure 5 and Figure 6 , the first connecting shaft 411 and the second connecting shaft 412 of the first flipping structure 41 and the first connecting shaft 411 and the second connecting shaft 412 of the second flipping structure 42 are all rotatably connected to the first housing 43 and the second housing 44. Semi-circular holes are provided at the positions of the first connecting shaft 411 and the second connecting shaft 412 on the first housing 43 and the second housing 44. After the first housing 43 and the second housing 44 are buckled and connected, the two semi-circular holes form a first circular through-hole. A section of circular column (as Figure 7 shown) is provided on both the first connecting shaft 411 and the second connecting shaft 412, and this section of circular column is in rotational fit with the corresponding first circular through-hole to achieve the rotational connection between the first connecting shaft 411 and the second connecting shaft 412 and the first housing 43 and the second housing 44, avoiding interference between the first housing 43 and the second housing 44 and the relative rotation of the first bracket 2 and the first flipping structure 41 and the second flipping structure 42, and also avoiding interference between the rotating bracket 5 and the first flipping structure 41 and the second flipping structure 42.

[0126] In addition, the first housing 43 and the second housing 44 are also used for rotatably connecting to the first bracket 2, the second bracket 3, and the rotating bracket 5. Taking the first bracket 2 as an example, specifically, semi-circular holes are provided at both ends of the first housing 43 and the second housing 44 close to the first bracket 2. After the first housing 43 and the second housing 44 are buckled and connected, a second circular through-hole is formed. Referring to Figure 5 , the first bracket 2 includes a first horizontal plate 21 and a first vertical plate 22 and a second vertical plate 23 respectively arranged at both ends of the first horizontal plate 21. A first connecting portion 211 is provided in the middle of the first horizontal plate 21 (referring to Figure 3 and Figure 6), both ends of the first connecting portion 211 are respectively connected and fixed to the first connecting shaft 411 of the first flipping structure 41 and the first connecting shaft 411 of the second flipping structure 42 (e.g., fixed by screws). Both ends of the first horizontal plate 21 are provided with second connecting portions 212. A third rotating shaft 2121 is provided on the second connecting portion 212. The third rotating shaft 2121 penetrates into the corresponding second circular through-hole and is rotationally matched with the second circular through-hole to realize the rotational connection between the first bracket 2 and the first housing 43 and the second housing 44. At the ends of the first vertical plate 22 and the second vertical plate 23 away from the first horizontal plate 21, third connecting portions 221 are provided. The third connecting portion 221 is used to mount the first rotating shaft 62 of the first rotating assembly 6.

[0127] Continue to refer to Figure 5 , the second bracket 3 includes a second horizontal plate 31, and a third vertical plate 32 and a fourth vertical plate 33 respectively provided at both ends of the second horizontal plate 31. At the ends of the third vertical plate 32 and the fourth vertical plate 33 away from the second horizontal plate 31, fourth connecting portions 321 are provided. The fourth connecting portion 321 is used to mount the first rotating shaft 62 of the second rotating assembly 7. Refer to Figure 8 , a fifth connecting portion 53 is provided on the rotating bracket 5. Both ends of the fifth connecting portion 53 are respectively connected and fixed to the second connecting shaft 412 of the first flipping structure 41 and the second connecting shaft 412 of the second flipping structure 42 (e.g., fixed by screws).

[0128] Further, the first housing 43 and the second housing 44 are detachably connected by fasteners such as screws. Refer to Figure 5 , a plurality of connection holes are provided on the first housing 43 along the circumferential direction. Correspondingly, a plurality of connection columns with threaded holes are provided on the inner wall of the second housing 44. The plurality of connection holes correspond to the plurality of connection columns one by one. The first housing 43 and the second housing 44 can be connected and fixed by screwing the screws through the connection holes and into the threaded holes. In other embodiments, a snap structure can also be provided on the first housing 43 and the second housing 44, and the two are detachably connected through the snap structure.

[0129] Optionally, refer to Figure 8 , the rotating and splicing screen bracket mechanism further includes a third rotating assembly 8. The second bracket 3 is rotatably connected to the flipping assembly 4 through the third rotating assembly 8. The third rotating assembly 8 includes a second rotating shaft 81 and a second locking assembly 82. Wherein, one end of the second rotating shaft 81 is rotationally connected to the flipping assembly 4 (e.g., Figure 5 shown), the other end is fixedly connected to the rotating bracket 5 and is rotatably connected to the second bracket 3. The second locking assembly 82 is sleeved and connected to the second rotating shaft 81. The second locking assembly 82 can limit the rotation of the second rotating shaft 81 around the first axis within a fourth preset angle range. As Figure 5As shown, in this embodiment, semi-circular holes are provided at both ends of the first housing 43 and the second housing 44 on the side close to the second bracket 3. After the first housing 43 and the second housing 44 are snap-connected, a third circular through-hole is formed. One end of the second rotating shaft 81 extends into the third circular through-hole and is rotationally engaged therewith, so as to realize the rotational connection between the second rotating shaft 81 and the flipping assembly 4. Since the rotating bracket 5 is fixedly connected to the second rotating shaft 81, the flipping assembly 4 and the rotating bracket 5 can relatively rotate through the rotational engagement between the second rotating shaft 81 and the third circular through-hole. By providing the second locking assembly 82, the second bracket 3 can adjust the angle within a fourth preset angle range, thereby adjusting the display angle of the second display screen 200.

[0130] Optionally, referring to Figure 9 and Figure 10 , the second locking assembly 82 includes a first gasket 821, a second gasket 822, a third limiting piece 823 and a third stop 824. The second rotating shaft 81 sequentially passes through the first gasket 821, the second gasket 822, the third limiting piece 823 and the third stop 824. As Figure 8 shown, a first bushing 52 extending in the first axis direction is provided on the rotating bracket 5. A first clamping protrusion 521 protrudes from the inner wall of the first bushing 52. The first gasket 821 can be rotationally engaged with the second rotating shaft 81, and a first clamping groove 8211 is provided on the first gasket 821. The first clamping protrusion 521 is clamped with the first clamping groove 8211.

[0131] As Figure 5 and Figure 8 shown, a second bushing 311 extending in the first axis direction is provided on the second bracket 3. A second clamping protrusion 3111 protrudes from the inner wall of the second bushing 311. As Figure 9 shown, the second gasket 822 can be rotationally engaged with the second rotating shaft 81, and a second clamping groove 8221 is provided on the second gasket 822. The second clamping protrusion 3111 is clamped with the second clamping groove 8221.

[0132] Furthermore, referring to Figure 9 , the third limiting piece 823 is fixedly connected to the second rotating shaft 81, and a fourth arc-shaped notch 8231 is provided on the third limiting piece 823 along the circumferential direction. When the second bushing 311 rotates relative to the second rotating shaft 81, the second clamping protrusion 3111 can move within the fourth arc-shaped notch 8231, so that the second rotating shaft 81 rotates within a fourth preset angle range.

[0133] In this embodiment, two second rotating shafts 81 and two second locking assemblies 82 are provided to improve the stability of the rotational connection. Correspondingly, second bushings 311 are provided at both ends of the second cross plate 31 of the second bracket 3, and first bushings 52 are provided at both ends of the rotating bracket 5.

[0134] In this embodiment, the third stopper 824 is used to limit the first gasket 821, the second gasket 822 and the third limiting piece 823 on the second rotating shaft 81, ensuring reliable connection between the second bracket 3 and the flipping assembly 4 and enabling stable support for the second display screen 200 at a preset position. Preferably, the third stopper 824 includes a second nut and a second pressing gasket. The second pressing gasket is sleeved on the second rotating shaft 81, and an external thread is provided at the end of the second rotating shaft 81. By screwing the second nut onto the second rotating shaft 81 to press the second pressing gasket against the third limiting piece 823, reliable connection between the second bracket 3, the rotating bracket 5 and the second rotating shaft 81 can be ensured.

[0135] Refer to Figure 9 and Figure 10 , preferably, there are two second gaskets 822, and the two second gaskets 822 are respectively arranged at both ends of the second convex 3111. When specifically assembling the flipping assembly 4, the rotating bracket 5 and the second bracket 3, the two ends of the fifth connecting portion 53 of the rotating bracket 5 are respectively connected and fixed to the second connecting shafts 412 of the first flipping structure 41 and the second flipping structure 42. Then, the second rotating shaft 81 is sequentially passed through the first bushing 52, the first gasket 821, one second gasket 822, the second bushing 311, the other second gasket 822, the third limiting piece 823 and the second pressing gasket, and then the second nut is screwed onto the second rotating shaft 81 to make the first bushing 52 dock with the second bushing 311, the first gasket 821 close to the adjacent second gasket 822, the third limiting piece 823 close to the adjacent second gasket 822, and the second pressing gasket close to the third limiting piece 823. When the second bracket 3 rotates relative to the rotating bracket 5, frictional forces can be generated between the closely attached first gasket 821 and second gasket 822 and between the adjacent third limiting piece 823 and second gasket 822, enabling the second bracket 3 to stay at any angle.

[0136] Such as Figure 14 , Figure 15 and Figure 16 shown, the second bracket 3 can respectively stay in three different states to support the second display screen 200, enabling the second display screen 200 to be displayed at different display heights. Preferably, the fourth preset angle range is from 0 degrees to 90 degrees, that is, the second bracket 3 can stay at any angle within the range parallel to and perpendicular to the fixing frame 1.

[0137] Further, one end of the second rotating shaft 81 sleeving the first gasket 821, the second gasket 822 and the third limiting piece 823 is also a square shaft. Correspondingly, square holes are formed in the first gasket 821, the second gasket 822 and the third limiting piece 823. The cooperation between the square holes and the square shaft enables the first gasket 821, the second gasket 822 and the third limiting piece 823 to be fixed to the second rotating shaft 81, thereby ensuring that the first gasket 821, the second gasket 822 and the third limiting piece 823 cannot rotate relative to the second rotating shaft 81.

[0138] Optionally, referring to Figure 10 , a plugging member is provided at one end of the second bushing 311 close to the third stop member 824. After the second nut is screwed in place, the opening of the second bushing 311 is plugged with the plugging member, which can prevent dust and impurities from entering the second bushing 311.

[0139] Optionally, referring to Figure 2 and Figure 11 , the rotating split-screen bracket mechanism further includes a fourth rotating assembly 9. The rotating bracket 5 is rotatably connected to the fixed frame 1 through the fourth rotating assembly 9. Referring to Figure 12 and Figure 13 , the fourth rotating assembly 9 includes a fixed seat 91 and a third locking assembly 92. Among them, the fixed seat 91 is installed on the fixed frame 1, and a rotating shaft 911 protrudes from the fixed seat 91. The rotating bracket 5 includes a fixing plate 51 (the two first bushings 52 are located at both ends of the fixing plate 51). A second rotating hole 511 is provided on the fixing plate 51. The rotating shaft 911 passes through the second rotating hole 511 and can rotate in cooperation with the second rotating hole 511. The third locking assembly 92 is sleeved and connected to the rotating shaft 911, and the third locking assembly 92 can limit the rotation of the rotating bracket 5 around the second axis within a fifth preset angle range.

[0140] That is, the fixed seat 91 is fixed on the fixed frame 1 and does not move. When driving the fixing plate 51 to rotate relative to the fixed frame 1 around the second axis, the second rotating hole 511 rotates in cooperation with the rotating shaft 911. When the fixing plate 51 rotates relative to the fixed frame 1 to the fifth preset angle, the fixing plate 51 and the rotating shaft 911 are locked by the third locking assembly 92, and the fixing plate 51 cannot rotate relative to the rotating shaft 911 anymore, so as to stably support the first display screen 100 and the second display screen 200.

[0141] In this embodiment, the fifth preset angle range is from 0 degree to 90 degrees. As Figure 27 and Figure 28 shown, when the first display screen 100 and the second display screen 200 are in a vertical screen state after being split-screened, it is defined that the rotation angle at this time is 0 degree. Along Figure 27Rotate the first display screen 100 and the second display screen 200 in the direction of the arrow. When the fixing plate 51 rotates 90 degrees relative to the fixing frame 1, the third locking component 92 locks the fixing plate 51 and the rotating shaft 911, and the first display screen 100 and the second display screen 200 are switched from the vertical screen state to the horizontal screen state. Of course, if you want to switch from the horizontal screen to the vertical screen, just rotate the first display screen 100 and the second display screen 200 in the opposite direction.

[0142] Optionally, refer to Figure 12 and Figure 13 , the third locking component 92 includes a fourth limiting piece 921, a third gasket 922 and a fourth gasket 923. Among them, the fourth limiting piece 921 is arranged at one end of the rotating shaft 911 extending out of the second rotating hole 511. A limiting groove 512 is concavely arranged on the fixing plate 51 in the circumferential direction of the second rotating hole 511, and the fourth limiting piece 921 is located in the limiting groove 512. The third gasket 922 is sleeved on the rotating shaft 911 and is located between the fixed seat 91 and the fixing plate 51. The fourth gasket 923 is sleeved on the rotating shaft 911 and is located between the bottom wall of the limiting groove 512 and the fourth limiting piece 921. In this embodiment, the fixed seat 91 is fixed to the fixing frame 1 by fasteners such as screws. After the third gasket 922 is sleeved on the rotating shaft 911, it is fixed to the fixed seat 91 by screws. After the fourth gasket 923 is sleeved on the rotating shaft 911, it is fixed to the bottom wall of the limiting groove 512 by screws, and the fourth limiting piece 921 is fixed to the end face of the rotating shaft 911 by screws. When the fixing plate 51 rotates relative to the rotating shaft 911, frictional forces can be generated between the third gasket 922 and the fixing plate 51 and between the fourth limiting piece 921 and the fourth gasket 923, so that the fixing plate 51 can stay at any angle.

[0143] Further, refer to Figure 12 , a fourth limiting protrusion 5121 protrudes from the side wall of the limiting groove 512. A third card slot 9231 is arranged on the fourth gasket 923. The third card slot 9231 can be clamped with the fourth limiting protrusion 5121. A fifth arc-shaped notch 9211 is arranged on the circumferential edge of the fourth limiting piece 921. When the rotating bracket 5 rotates relative to the rotating shaft 911, the fourth limiting protrusion 5121 can move in the fifth arc-shaped notch 9211, so that the rotating bracket 5 rotates within a fifth preset angle range. As [[ID={124]]Figure 1 and Figure 11 shown, in the vertical screen state, the fourth limiting protrusion 5121 is clamped with the upper end of the fifth arc-shaped notch 9211. When the first display screen 100 and the second display screen 200 are Figure 27 rotated from the vertical screen state in the direction of the arrow to the horizontal screen state as shown in Figure 28 , the fourth limiting protrusion 5121 is clamped with the lower end of the fifth arc-shaped notch 9211. That is, the fourth limiting protrusion 5121 and the fifth arc-shaped notch 9211 are switched from the vertical screen locking state to the horizontal screen locking state.
