[0027] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0028] like Figure 1-8 As shown, the utility model provides an angle-adjustable lifting conference screen, including a chassis 10, a display mechanism 20, a lifting mechanism 30 and a controller 40. The chassis 10 is vertically arranged and hollow inside. The upper end of the chassis 10 is provided with an opening that penetrates the inside thereof. The lifting mechanism 30 is installed in the chassis 10. The display mechanism 20 includes a display screen 200 and a support frame 201 for supporting the display screen 200. A swing shaft 202 is rotatably arranged on the upper end of the support frame 201. The swing shaft 202 is horizontally arranged and can rotate at the opening. The display screen 20 0 is fixedly connected to the swing shaft 202, a swing assembly for driving the swing shaft 202 to rotate is provided on the support frame 201, an output end of the lifting mechanism 30 is connected to the support frame 201, when the lifting mechanism 30 drives the display screen 200 to rise above the chassis 10 through the opening, the swing assembly can drive the swing shaft 202 to rotate, so that the display screen 200 swings about the horizontal axis of the swing shaft 202, and the controller 40 is electrically connected to the lifting mechanism 30 and the swing assembly respectively to control the operation of the lifting mechanism 30 and the swing assembly.

[0029] In this embodiment, when the display screen 200 is not needed, the display mechanism 20 is driven to descend to the inside of the chassis 10 by the lifting mechanism 30, so that the display mechanism 20 is stored in the chassis 10 for easy arrangement and storage; when the display screen 200 is needed, the display screen 200 is driven to rise to the top of the chassis 10 through the opening by the lifting mechanism 30, so as to facilitate the use of the display screen 200. After the display screen 200 rises to the top of the chassis 10, when the angle of the display screen 200 needs to be adjusted, the operation of the swing assembly is controlled by the controller 40, and the swing assembly drives the swing shaft 202 to rotate, and the swing shaft 202 rotates at the opening, and then the display screen 200 swings left and right about the horizontal axis of the swing shaft 202, thereby realizing the adjustment of the angle of the display screen 200 to meet the needs of users. The operation of the lifting mechanism 30 and the swing assembly is controlled by the controller 40, so as to realize the intelligent control of the lifting and swinging of the display screen 200, and the operation is more convenient.

[0030] It should be noted that the controller 40 of this embodiment can be composed of a control module and a remote control module. The control module is electrically connected to the lifting mechanism 30 and the swing assembly, respectively, to control the operation of the lifting mechanism 30 and the swing assembly. The remote control module can be connected to the control module in a wired manner or in a wireless manner. The operator can control the operation of the lifting mechanism 30 and the swing assembly through the remote control module. As another optional embodiment, the controller 40 can be a control module and a navigation module installed in the chassis 10, and a predetermined written program is used for full-automatic, unmanned and autonomous control.

[0031] As a preferred embodiment, the display mechanism 20 also includes a magnetic part 206 and a Hall component, the swing component includes a rotating part 204 and a rotating driving part 203 that drives the rotating part 204 to rotate, the rotating part 204 is connected to the swing shaft 202 through a transmission mechanism, the magnetic part 206 is arranged on the rotating part 204, the Hall component is arranged on the support frame 201, the Hall component is aligned with the rotation path of the magnetic part 206, when the magnetic part 206 moves to align with the Hall component, the Hall component can receive the signal of the magnetic part 206, the Hall component is electrically connected to the controller 40, and the controller 40 is used to adjust the output or rotation direction of the rotating driving part 203 according to the signal detected by the Hall component.

[0032] In this embodiment, the Hall component is used to detect the signal of the magnetic member 206, which is specifically the magnetic field signal of the magnetic member 206. Since the magnetic member 206 is arranged on the rotating member 204, when the rotating driving member 203 drives the rotating member 204 to rotate, the magnetic member 206 rotates with the rotating member 204. When the magnetic member 206 rotates to align with the Hall component, the Hall component detects the signal of the magnetic member 206 and sends the signal to the controller 40. The controller 40 adjusts the output or rotation direction of the rotating driving member 203 according to the signal detected by the Hall component, and then accurately positions the display screen 200 at the preset swing position. Therefore, by detecting the signal of the magnetic member 206 by the Hall component, the in-place information of the magnetic member 206 can be accurately determined, so as to accurately position and lock the swing of the display screen 200, and at the same time, the display screen 200 can be swung within the set angle range, with high control accuracy and high flexibility.

[0033] Of course, those skilled in the art may also dispose the magnetic member 206 on the support frame 201 and dispose the Hall component on the rotating member 204 as required.

[0034] As a preferred embodiment, the transmission mechanism includes a fixed block 210 and a connecting rod 205, the fixed block 210 is fixedly connected to the swing shaft 202, one end of the connecting rod 205 is rotatably connected to the fixed block 210, and the other end of the connecting rod 205 is rotatably connected to the rotating member 204, and the connecting rod 205 is driven to move by the rotating member 204, so as to pull the swing shaft 202 to rotate through the connecting rod 205.

[0035] In this embodiment, the rotating driving member 203 provides power to the rotating member 204 to rotate the rotating member 204. After the connecting rod 205 is subjected to the rotational force of the rotating member 204, it pulls the fixed block 210 to rotate the swing shaft 202, thereby causing the display screen 200 to swing about the horizontal axis of the swing shaft 202. The driving method using the connecting rod 205 has lower cost and simple and reliable connection.

[0036] As a preferred embodiment, the Hall component includes a Hall plate 207 and a first Hall element 208 and a second Hall element 209 installed on the Hall plate 207. The support frame 201 is provided with a fixing seat 211 for fixing the Hall plate 207. The first Hall element 208 and the second Hall element 209 are located in the same plane. The first Hall element 208 serves as the starting point of the angle response, and the second Hall element 209 serves as the end point of the angle response.

[0037] In this embodiment, when the rotating member 204 drives the magnetic member 206 to rotate to align with the first Hall element 208, the first Hall element 208 sends a detection signal to the controller 40, and the controller 40 controls the rotating driving member 203 to stop running. At this time, the display screen 200 is positioned at the starting position, such as Figure 7 As shown; when the rotating member 204 drives the magnetic member 206 to rotate to align with the second Hall element 209, the second Hall element 209 sends a detection signal to the controller 40, and the controller 40 controls the rotating driving member 203 to stop running. At this time, the display screen 200 is positioned at the end position, as shown Figure 8 Therefore, by setting the first Hall element 208 and the second Hall element 209, the display screen 200 can be accurately positioned at different positions.

[0038] It is understandable that those skilled in the art may further provide three, four or more Hall elements on the Hall plate 207 as required to meet positioning requirements at different angles.

[0039] It should be noted that in order to facilitate the control of the swing angle of the display screen 200, adjustment buttons + and - can be set on the chassis 10, and the swing angle of the display screen 200 can be controlled by using buttons + and -; when there is no operation on the adjustment buttons + and -, the maximum swing angle of the display screen 200 after the reset is completed is preferably 30 degrees. Of course, the maximum swing angle can be set according to actual needs; by adjusting buttons + and -, a control signal is sent to the controller 40, and the controller 40 receives the control signal and sends a signal to control the rotating drive member 203 to rotate the set angle (such as 1 degree), and drives the display screen 200 to swing to the corresponding angle through the connecting rod 205.

[0040] As a preferred embodiment, the magnetic member 206 is a magnet. Those skilled in the art will appreciate that the magnetic member 206 can be any form of component capable of releasing a magnetic field, such as a permanent magnet, an electromagnet, an electromagnetic coil, and the like.

[0041] As a preferred embodiment, the rotating member 204 is a transmission wheel, and a groove for accommodating the magnetic member 206 is provided on the transmission wheel. Figure 5 , the magnetic member 206 is fixed in the groove of the transmission wheel for easy installation; it should be noted that the above-mentioned rotation path is the track of the magnetic member 206 as the transmission wheel rotates one circle. In addition, those skilled in the art should understand that the setting position of the magnetic member 206 on the transmission wheel is not limited to Figure 5The position shown in the figure can be any position on the transmission wheel. It can be understood by those skilled in the art that the detection accuracy of the rotation angle of the magnetic member 206 by the Hall assembly can be improved by placing the magnetic member 206 at a position close to the rim of the transmission wheel, compared with placing the magnetic member 206 at a position far from the rim of the transmission wheel. This is because when the magnetic member 206 rotates through the same angle, the travel path of the position far from the rotation center is longer.

[0042] As a preferred embodiment, the rotating drive member 203 uses a DC reduction motor. The DC reduction motor is a micro reduction motor, which has the advantages of saving space, being reliable and durable, having high overload capacity, low vibration, low noise, and high energy saving. Of course, the rotating drive member 203 can also select other drive members, such as a rotary cylinder, which is not specifically limited here.

[0043] As a preferred embodiment, the display mechanism 20 further includes at least two support plates 212, one end of at least two support plates 212 is respectively fixedly connected to the support frame 201, and the other end of at least two support plates 212 is provided with a pivot hole, and the swing shaft 202 is provided with an axis section matched with the pivot hole, and the axis section of the swing shaft 202 is pivotally connected to the pivot hole of the support plate 212. The swing shaft 202 and the support frame 201 are rotatably installed through the support plate 212, which has a simple structure and is easy to install.

[0044] As a preferred embodiment, the lifting mechanism 30 includes a lifting drive member 301, a synchronous conveyor belt 302 and a synchronous wheel, the synchronous wheel is installed at the output end of the lifting drive member 301, a synchronous belt connecting plate 213 is provided on the support frame 201, and the synchronous conveyor belt 302 is connected between the synchronous wheel and the synchronous belt connecting plate 213.

[0045] As a preferred embodiment, the chassis 10 is provided with a vertically arranged guide rod 101 and a guide rail 103, the support frame 201 is provided with a slider 214 that slides with the guide rod 101, and a buffer member 102 is provided at the bottom end of the guide rod 101. The support frame 201 is slidably connected with the guide rail 103 to guide the support frame 201 to move up and down along the guide rail 103.

[0046] In this embodiment, the slider 214 cooperates with the guide rod 101, and a buffer member is provided on the guide rail 103, so as to guide and buffer the lifting and lowering of the support frame 201, so that the lifting and lowering of the display mechanism 20 is smoother and more stable; through the design of the guide rail 103, the support frame 201 can be stably supported in the chassis 10, ensuring the normal use of the display screen 200.

[0047] It should be noted that all electronic components involved in the present invention adopt the existing technology, and the above-mentioned components are electrically connected to the controller 40, and the control circuit between the controller 40 and each component is the existing technology.
