Description

Technical Field

[0001] This invention relates to the field of conference display terminal technology, and in particular to an all-in-one LCD conference machine with voice-enabled intelligent AI thermal printing. Background Technology

[0002] With the popularization of smart office scenarios, LCD all-in-one conference machines have become standard equipment in conference rooms, enabling interactive functions such as touch writing, document presentation, and remote conferencing. However, existing all-in-one conference machines still have two significant shortcomings: First, the devices generally only have display and interactive capabilities. If meeting annotations and minutes need to be printed, an external independent printing device is required, which is cumbersome and time-consuming, making it difficult to achieve real-time output of meeting content. Second, the tilt angle of the conference screen mostly uses a damped hinge adjustment. After long-term and frequent use, the damping is prone to decay, and problems such as the screen sliding down on its own, angle deviation, and loosening are likely to occur. The self-locking reliability is insufficient, which cannot meet the needs of long-term stable use. Summary of the Invention

[0003] One objective of this invention is to provide an all-in-one LCD conference machine with voice-enabled intelligent AI thermal printing capabilities.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an all-in-one LCD conference machine with voice-enabled intelligent AI thermal printing, comprising a bracket, connecting frame, rotating rod, connecting plate, snap-fit ​​shaft, connecting block, connecting shaft, thermal printer, and conference screen; two connecting frames are fixedly connected to the top of the bracket, and the rotating rod is rotatably mounted between the two connecting frames. At least two sets of connecting plate assemblies are provided on the outer side of the rotating rod, each set of connecting plate assemblies containing two connecting plates. A bidirectional threaded section is provided on the outer side of the rotating rod corresponding to the position of each set of connecting plate assemblies, and the two connecting plates in the same set are respectively threaded into the positive and negative threaded portions of the corresponding bidirectional threaded section; the snap-fit ​​shaft is fixedly connected to the side of the two connecting plates in the same set that are close to each other, and the opposite ends of the two snap-fit ​​shafts are respectively provided with snap-fit ​​grooves; the side of the conference screen facing the bracket is fixedly connected to the connecting rod. The system comprises at least three connecting blocks, each with several equidistant locking teeth fixed on both sides. These locking teeth are adapted to and engage with the corresponding locking slots on the sides. A connecting shaft is rotatably mounted between two adjacent connecting blocks, and the connecting shaft passes through and rotatably connects to the locking shaft and connecting plate of the corresponding group. A thermal printer is fixedly mounted at the bottom of the conference screen, and the thermal printer is signal-connected to the conference screen, enabling synchronous printing of the conference screen's display content. A tension spring is fixedly connected between two connecting plates in the same group, located on one side of the rotating rod. The tension spring applies opposing tension to the two connecting plates, keeping the locking slots and locking teeth in a self-locking state to prevent the conference screen from shifting or loosening under external force. Rotating the rotating rod drives the two connecting plates in the same group to move in opposite directions along the bidirectional threaded section, thereby disengaging the locking slots from the locking teeth and releasing the self-locking mechanism.

[0005] Furthermore, six connecting plates are provided on the outer side of the rotating rod. The six connecting plates are divided into three groups of connecting plate assemblies along the axial direction of the rotating rod. Three bidirectional threaded sections are correspondingly opened on the outer side of the rotating rod. The three bidirectional threaded sections are arranged at intervals along the axial direction of the rotating rod. Three connecting blocks are fixedly connected to the side of the conference screen facing the bracket. The three connecting blocks are arranged one-to-one with the three groups of connecting plate assemblies. The locking teeth on both sides of each connecting block are respectively engaged with the locking grooves of the corresponding group of locking shafts on both sides.

[0006] Furthermore, the teeth on both sides of each connecting block are equidistantly arranged along the circumferential rotation of the connecting block, and the inner wall contour of the slot is adapted to the shape of the teeth; a tension spring is provided between the two connecting plates of each connecting plate assembly, and the two ends of the tension spring are fixedly connected to the side wall of the corresponding connecting plate, and the extension and retraction direction of the tension spring is parallel to the axis of the rotating rod.

[0007] Furthermore, the outer surface of the thermal printer is equipped with a display screen and mechanical buttons. The mechanical buttons are used to manually control the printing start / stop, paper feed, and printing parameter adjustment. The thermal printer integrates a remote control module and a Bluetooth communication module, which can respectively realize remote printing command reception and direct printing to nearby terminal devices.

[0008] Furthermore, the thermal printer also integrates an AI content processing module. This AI content processing module establishes a data connection with the conference screen and can automatically identify, optimize the layout of handwritten annotations, presentations, and meeting minutes on the conference screen, as well as remove redundant information, before driving the thermal printing unit to complete the paper output.

[0009] Furthermore, the conference screen has a built-in LCD conference system module that supports multi-touch writing, document presentation, simultaneous annotation by multiple users, and local storage of meeting minutes; the thermal printer establishes a data transmission connection with the conference screen via a wired connection, and can retrieve stored files and real-time written content from the conference screen for printing output in real time.

[0010] Furthermore, two fixing plates are fixedly connected to the side of the conference screen facing the bracket. The two ends of the connecting shaft are respectively rotatably mounted on the two fixing plates. The connecting blocks are all fixedly set in the area between the two fixing plates. The connecting shaft passes through the connecting blocks, the snap-fit ​​shaft and the connecting plates, forming a multi-part coordinated rotational support structure.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] (1) The present invention uses a combination structure of bidirectional threaded rotating rod, connecting plate, locking tooth groove and tension spring. Under normal conditions, the tension spring continuously provides opposing tension to keep the locking groove and locking tooth tightly engaged, fundamentally avoiding the problem of angle loosening and self-deflection of the conference screen after long-term use. When adjusting, only rotating the rotating rod is needed to unlock multiple locking structures simultaneously. The operation is convenient and it can automatically reset and lock after releasing. The structural reliability is far higher than that of traditional damping rotating shaft.

[0013] (2) In this invention, the thermal printer is directly integrated into the bottom of the conference screen and linked with the internal data of the conference system. No external printing equipment or additional wiring is required, saving conference room space. The AI ​​content processing module can automatically recognize handwritten annotations, organize the layout, and remove redundant content, directly outputting well-organized paper conference documents, eliminating the need for manual sorting and greatly improving the efficiency of conference recording.

[0019] The present invention will now be further described in conjunction with specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] In the description of this invention, it should be noted that directional terms such as "center," "lateral," "longitudinal," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this invention.

[0021] It should be noted that the terms "first" and "second" in the specification and claims of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0022] One preferred embodiment of the present invention, such as Figures 1 to 4 As shown in the figure, the LCD conference all-in-one machine with intelligent AI thermal printing described in this embodiment consists of three parts: a support and adjustment mechanism, a conference display body, and an intelligent printing unit.

[0023] The support and adjustment mechanism includes a bracket 1, a connecting frame 2, a rotating rod 3, a connecting plate 4, a locking shaft 5, and a tension spring 14. The bracket 1 serves as the bottom load-bearing structure of the entire unit, with two connecting frames 2 symmetrically fixedly mounted on its top. The rotating rod 3 is horizontally mounted between the two connecting frames 2 and can rotate freely around its own axis. The rotating rod 3 has three parallel bidirectional threaded sections, each containing two threads with opposite directions of rotation. Two connecting plates 4 are provided for each bidirectional threaded section, forming a screw-nut transmission engagement with the positive and negative threads of that section. When the rotating rod 3 rotates around its axis, the two connecting plates 4 within the same section will synchronously translate towards or away from each other along the axial direction of the rotating rod 3. A locking shaft 5 is fixedly connected to the side of each connecting plate 4 facing the conference screen 13, and recessed slots 6 are formed on the opposite end faces of the two opposing locking shafts 5. A tension spring 14 is fixedly connected between the two connecting plates 4 in the same group. The extension and retraction direction of the tension spring 14 is parallel to the axis of the rotating rod 3, and it always applies opposing tension forces to the two connecting plates 4.

[0024] The main display unit is the conference screen 13. Two vertically arranged fixing plates are fixed to the back of the screen facing the bracket 1. A connecting shaft 9 is horizontally rotatably mounted between the two fixing plates. Three connecting blocks 7 are fixedly installed on the connecting shaft 9 at positions corresponding to the three sets of connecting plate assemblies. Each connecting block 7 has several equidistant locking teeth 8 on its left and right sides along its own rotational circumference. The outer contour of the locking teeth 8 matches the inner wall contour of the locking groove 6, allowing for a snap-fit ​​connection. The connecting shaft 9 also passes through the corresponding holes of the locking shaft 5 and the connecting plate 4, allowing the conference screen 13 to be tilted around the axis of the connecting shaft 9.

[0025] Under normal conditions, the tension of the spring 14 drives the two connecting plates 4 in the same group to move closer together, so that the groove 6 at the end of the locking shaft 5 and the tooth 8 on the side of the connecting block 7 are tightly engaged, restricting the rotational freedom of the connecting block 7 and the connecting shaft 9, thereby achieving angle self-locking of the conference screen 13. This effectively prevents the screen from deflecting or loosening due to external force or its own weight. When the angle needs to be adjusted, the operator rotates the lever 3. Through the transmission action of the bidirectional thread, the two connecting plates 4 are driven to move axially in opposite directions against the tension of the spring 14, causing the groove 6 to disengage from the tooth 8. At this time, the conference screen 13 can be freely moved to adjust the pitch angle. After adjusting to the target angle, the lever 3 is released, and the contraction tension of the spring 14 drives the two connecting plates 4 to return to their original positions. The groove 6 and the tooth 8 re-engage, thus completing the angle locking.

[0026] The intelligent printing unit is a thermal printer 10, which is fixedly installed on the bottom edge of the conference screen 13 and establishes a wired data connection with the conference screen 13 through an internal cable. The front of the thermal printer 10 is equipped with a display screen 11 and mechanical buttons 12. The display screen 11 is used to display printing status, paper balance, and parameter setting information. The mechanical buttons 12 allow the operator to manually control printing start / stop, paper feed, and printing parameter adjustment locally on the device.

[0027] The thermal printer 10 integrates a Bluetooth communication module, a remote control module, and an AI content processing module. The Bluetooth communication module can connect directly to terminal devices such as mobile phones and laptops at close range to print meeting documents directly from the terminal. The remote control module can connect to the office LAN to receive print jobs issued by the remote meeting system. The AI ​​content processing module is connected to the meeting system data of the meeting screen 13, and can acquire handwritten annotations, presentation pages, meeting minutes, and other content on the meeting screen in real time. It automatically performs text recognition, layout standardization, and redundant content removal to generate standardized print files and drive the thermal printing unit to output paper documents without the need for manual secondary sorting and formatting.

[0028] The conference screen 13 has a built-in LCD conference system module, which has conventional conference functions such as multi-touch writing, multi-format document presentation, multi-person synchronous annotation, and local storage of meeting records. The historical meeting records stored in its internal storage can also be directly retrieved and printed out through the thermal printer 10.

[0029] Working principle:

[0030] In use, under normal conditions, the tension spring (14) is in a contracted state, continuously applying opposing axial tension to the two connecting plates (4) in the same group, causing the two connecting plates (4) to drive their respective locking shafts (5) to move closer to each other. The locking groove (6) at the end of the locking shaft (5) and the locking tooth (8) on the side of the connecting block (7) are tightly engaged. At this time, the rotational freedom of the connecting block (7) is restricted by the locking groove (6), and the connecting shaft (9) fixed to the connecting block (7) cannot rotate freely, thereby keeping the conference screen (13) locked at the current pitch angle, effectively preventing the screen from being touched by external force or from deflecting and loosening due to its own weight, and achieving normal self-locking.

[0031] When the angle of the conference screen (13) needs to be adjusted, the rotating rod (3) is rotated directly. The bidirectional threaded section on the rotating rod (3) drives the two connecting plates (4) in the same group to overcome the tension of the tension spring (14) and move synchronously in opposite directions along the axis of the rotating rod (3). This causes the two locking shafts (5) to separate synchronously, so that the locking groove (6) and the locking tooth (8) disengage, and the rotation restriction on the connecting block (7) is released. At this time, the connecting shaft (9) can rotate freely, and the operator can move the conference screen (13) around the axis of the connecting shaft (9) to adjust the pitch angle.

[0032] After the angle is adjusted to the correct position, release the rotating rod (3). The contraction force of the tension spring (14) will drive the two connecting plates (4) to reset along the axial direction, causing the slot (6) of the locking shaft (5) to re-engage with the corresponding tooth (8), thus completing the angle locking again. The entire adjustment process only requires rotating the rotating rod (3) to simultaneously complete the unlocking and locking, making the operation convenient. Moreover, the rigid locking structure of the tooth and slot has a service life much longer than that of the traditional damping rotating shaft, and there is no problem of attenuation or loosening after long-term use.

[0033] During operation, the built-in LCD conference system module of the conference screen (13) records touch-written content, presentation pages, multi-person annotation information, and meeting minutes in real time and stores them in the local storage unit. The thermal printer (10) and the conference screen (13) establish data interaction through internal wired lines, supporting four types of print triggering methods:

[0034] The conference system is triggered: the operator selects the print command on the system interface of the conference screen (13), and the conference screen transmits the currently displayed content or the specified conference record file to the AI ​​content processing module of the thermal printer (10);

[0035] Local manual trigger: The printing command can be initiated directly through the mechanical button (12) on the surface of the thermal printer (10), and the default meeting record in the conference screen (13) can be retrieved for printing. At the same time, parameters such as print density and paper feed can be adjusted through the mechanical button (12).

[0036] Bluetooth direct connection trigger: The external terminal device establishes a connection with the thermal printer (10) through the Bluetooth communication module and directly sends the meeting files in the terminal for printing;

[0037] Remote control trigger: The remote conference terminal sends a printing task to the remote control module via the network. After receiving the task, the thermal printer (10) retrieves the corresponding file in the conference screen (13) and executes the printing.

[0038] Before being printed, all printed content is processed by the AI ​​content processing module: the module automatically recognizes handwritten annotations, standardizes page layout, removes redundant and altered content, organizes the meeting content into a standardized layout format, and then drives the thermal printing unit to complete thermal printing, finally outputting a neat paper meeting document; the display screen (11) displays the printing progress, paper balance and equipment status in real time, which is convenient for operators to view.

[0039] The basic principles, main features, and advantages of this invention have been described above. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made without departing from the spirit and scope of the invention, and all such changes and modifications fall within the scope of the invention as claimed.
