The structure and lifting process of the lifting assembly 2 are known. The lifting motor 22 adopts a 60KTYZ small claw pole synchronous motor. For the other structural details, please refer to Chinese Patent CN2024209943607, which will not be described in detail here.

[0043] In a preferred embodiment, the flipping assembly 6 includes a limiting seat plate 60, a flipping limiting strip 61, a flipping pull strip 62, a flipping seat 63, a flipping plate 64, and a guide bearing 65. The limiting seat plate 60 is fixed inside the housing 1. The flipping limiting strip 61 is installed on the limiting seat plate 60 and connected to the flipping pull strip 62. The flipping limiting strip 61 has two strip-shaped holes 66 and is connected to the limiting seat plate 60 by screws. The flipping limiting strip 61 can move up and down within the stroke of the strip-shaped holes 66. The lower end of the flipping pull strip 62 is provided with an elongated hole 67 and is connected to the flipping limiting strip 61 by screws. The flipping pull strip 62 can move up and down within the stroke of the elongated hole 67.

[0044] A first tension spring (not shown) is also provided between the flipping limiting strip 61 and the flipping pulling strip 62. The end of the flipping limiting strip 61 extends outward to form a protrusion 68. A first spring hole 611 is provided adjacent to the protrusion 68. A first spring hook 612 is provided at the lower end of the flipping pulling strip 62. The first tension spring is connected between the first spring hole 611 and the second spring hook 622. Under the force of the first tension spring, the flipping limiting strip 61 remains in an upward state.

[0045] The flip base 63 is provided with a second spring hole 621, and the flip pull bar 62 is also provided with a second spring hook 622 on both sides. A second tension spring (not shown) is provided between the flip base 63 and the flip pull bar 62. Under the action of the second tension spring, the flip pull bar 62 remains in an upward state.

[0046] The flip pull bar 62 is swayably mounted on the flip base 63 and connected to one end of the flip plate 64. Specifically, the flip plate 64 is rotatably mounted on the flip base 63 by the first bolt 69. The flip base 63 is also provided with an arc-shaped hole 631. One end of the flip plate 64 is rotatably connected to the flip pull bar 62 by the second bolt 691. The second bolt 691 connecting the two is inserted into and passes through the arc-shaped hole 631 so that the two are rotatably connected, and the two swing along the arc-shaped hole 631.

[0047] The other end of the flip plate 64 is provided with a guide bearing 65, and the end of the flip plate 64 is provided with an outwardly protruding post 641. The post 641 is sleeved on the guide bearing 65, and the guide bearing 65 is in contact with the back of the flip door 3. When the flip plate 64 extends to the back of the flip door 3 and the post 641 rotates with the flip plate 64, the guide bearing 65 installed on the post 641 is always in contact with the back of the flip door 3, thereby closing the flip door 3.

[0048] In a preferred embodiment, when the first and second tension springs are not under force, the flipping limit bar 61 and the flipping pull bar 62 remain in an upward state, so the flipping plate 64 is not under force, and the bolt 69 connecting the flipping plate 64 and the flipping pull bar 62 is at the top of the arc-shaped hole 631. At this time, when the guide bearing 65 installed on the protrusion 641 abuts against the back of the flipping door 3, no force is generated, and the flipping door 3 is in the open state.

[0049] When the screen 9 moves downward, the bottom of the mounting base 50 will abut against the protrusion 68 of the flip limit bar 61, causing the first tension spring on the flip limit bar 61 to be stressed and move downward. The downward-moving flip limit bar 61 will simultaneously pull the second tension spring, causing the flip pull bar 62 to be stressed and move downward. The downward-moving flip pull bar 62 will drive the flip plate 64 to swing, so that the bolt 69 connecting the flip plate 64 and the flip pull bar 62 is at the bottom of the arc-shaped hole 631. At this time, when the guide bearing 65 installed on the protrusion 641 abuts against the back of the flip door 3, it generates force, and the flip door 3 is in the closed state.

[0050] In a preferred embodiment, the electronic component group 4 includes a component cover plate 40, a wiring board 41, and a circuit board 42. It also includes known display driver boards, power boards, control boards, etc. The circuit board 42, display driver boards, power boards, and control boards are disposed inside the component cover plate 40, and the wiring board 41 is disposed on one side of the component cover plate 40 for mounting and fixing the power interface.

[0051] In a preferred embodiment, the screen holder 5 includes a mounting base 50 and a screen protective cover 51. The screen protective cover 51 is disposed at the upper end of the mounting base 50, and the interior of the screen protective cover 51 is used to install the screen 9.

[0052] In a preferred embodiment, the upper end face of the mounting base 50 is provided with a mounting platform 52, which fixes the screen protector 51 with bolts 69. The lower end face of the mounting base 50 is provided with two rotating connection holes 53. The rotating connection holes 53 are blind holes and are provided with strip-shaped grooves 54 for rotating the rotating connector 7. Screw holes 55 are provided on both sides of the strip-shaped grooves 54 to install and fix the shaft 71 with screws. In addition, an elevation angle limiting plate 56 is provided between the two rotating connection holes 53. Spring hangers 57 are also provided on both sides of the elevation angle limiting plate 56 for auxiliary limiting.

[0053] In a preferred embodiment, the rotating connector 7 includes a connecting plate 70 and a fixed shaft 71. One end of the connecting plate 70 is mounted on the lifting assembly 2, and the other end of the connecting plate 70 is inserted into the strip groove 54 of the rotating connecting hole 53 and rotatably connected to the fixed shaft 71. Both ends of the fixed shaft 71 are fixed in the screw holes 55 of the rotating connecting hole 53 by screws. Specifically, the fixed shaft 71 is installed in the rotating connecting hole 53 and rotatably inserted into the connecting plate 70 for connection. During the lifting process, it rotates with the change of the angle adjustment module 8 to match the change of the screen 9's tilt angle. Specifically, the sliding wheel 82 moves upward along the inclined surface of the tilt angle top plate 80, and the lifting support plate 81 tilts the screen base 5 towards the rear of the screen 9. During the tilting process, the fixed shaft 71 rotates with the rotation of the mounting base 50; when the screen 9 descends, it rotates in the opposite direction.

[0054] In a preferred embodiment, the angle adjustment module 8 consists of two sets, respectively arranged on both sides of the lifting assembly 2. The angle adjustment module 8 includes an elevation top plate 80, a lifting support plate 81, and a sliding wheel 82. The elevation top plate 80 is fixed on the housing 1, and the lower end of the lifting support plate 81 is provided with a sliding wheel 82. The lifting support plate 81 is arc-shaped. During the upward movement of the lifting support plate 81, the sliding wheel 82 will contact the elevation top plate 80 fixed on the housing 1 and move upward along the inclined surface of the elevation top plate 80. The inclined elevation top plate 80 will cooperate with the lifting support plate 81 to tilt the screen cover 51 backward until the highest point of the lifting assembly 2. Conversely, the change is reversed during the downward movement. In this application, the inclined surface angle of the elevation top plate 80 is 65 to 75°. This embodiment takes 70° as an example.

[0055] In summary, the multimedia screen is housed within a screen holder, and a lifting assembly drives the screen on the screen holder to move up and down. During the lifting process, the rotating connector between the lifting assembly and the screen holder rotates according to the lifting state to cooperate with the angle adjustment module to adapt to changes in the screen's tilt angle. The angle adjustment module controls the change in the screen's tilt angle during the rising or falling process to adjust the screen's tilt angle state to adapt to the mutual changes between the tilt angle and the no tilt angle state. Compared with the prior art, the angle adjustment of this application adopts a mechanical control method for tilt angle, which is more stable and will not easily lead to the weakening of support force after long-term use, resulting in poor screen angle during use and causing discomfort to the user.

[0056] Although embodiments of the present invention have been shown above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention.
