Description

Technical Field

[0001] This invention belongs to the field of electronic whiteboard technology, specifically relating to an Internet of Things (IoT) smart whiteboard. Background Technology

[0002] An IoT smart whiteboard is a modern whiteboard system integrating IoT technology, typically used in education, corporate meetings, and remote collaboration. It combines the writing function of a traditional whiteboard with the interactivity of modern digital technology, enabling real-time sharing, saving, editing, and remote access of content via internet connectivity. Its features include: Real-time interaction: Users can write, draw, and manipulate graphics on the whiteboard via touch, with real-time feedback from the system, supporting multiple participants simultaneously; Remote collaboration: Through IoT technology, participants can connect to the smart whiteboard from different locations via network for remote collaboration and discussion; Multiple input methods: In addition to touchscreen input, it also supports input methods such as electronic pens, mobile phones, and tablets; Intelligent recognition and processing: Some high-end smart whiteboards also have text recognition and image processing functions, automatically converting handwritten content into text, and automatically recognizing and saving graphics or data.

[0003] Due to their numerous performance advantages, IoT smart whiteboards are being adopted by an increasing number of educational institutions and enterprises, especially in distance education and online meetings, where they greatly improve interactivity and work efficiency. Currently, there are various types of IoT smart whiteboards on the market, but most have certain shortcomings in use. Most existing smart whiteboards use a fixed installation structure, limiting their use to fixed positions and angles, significantly impacting the presentation effect. Secondly, existing smart whiteboards have poor adjustability; their extension whiteboards are usually only for auxiliary writing and display, lacking synchronization and adjustability for different presentation needs based on the speaker's and participants' positions and heights, thus affecting the user experience to some extent. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an Internet of Things smart whiteboard.

[0005] The technical solution adopted to solve the above technical problems is: an Internet of Things smart whiteboard, including a whiteboard body, a mounting and fixing mechanism for fixing the whiteboard is fixedly installed at the rear end of the whiteboard body, an installation adjustment mechanism is installed in the middle of the rear end of the mounting and fixing mechanism, and the rear end of the installation adjustment mechanism is fixed to the wall;

[0006] A set of horizontally arranged sliding support mechanisms is fixedly installed on the rear end face of the whiteboard body and the mounting and fixing mechanism, and a rotating support mechanism is slidably installed on both sets of sliding support mechanisms.

[0007] Both sets of rotating support mechanisms are rotatably connected to auxiliary whiteboards. With the support of the sliding support mechanism and the rotating support mechanism, the two sets of auxiliary whiteboards can slide, unfold, and store. The rear ends of both sets of auxiliary whiteboards are rotatably connected to auxiliary support mechanisms.

[0008] Furthermore, the whiteboard body includes a main display screen, an intelligent camera recognition module is provided at the top front end of the main display screen, an operation component is fixedly connected to the bottom of the main display screen, the operation component is provided with a switch module and a data external module, and a power cord is connected to the rear end of the operation component.

[0009] Through the above technical solution, the main display screen is a large-size industrial-grade LCD screen, which adopts infrared sensing technology and is equipped with an intelligent camera recognition module. It supports functions such as handwriting, multi-touch, gesture recognition, and voice recognition, making it convenient for operators to use in actual use. At the same time, the bottom of the main display screen is equipped with operating components, which allows operators to quickly connect to various types of data terminals to realize functions such as data transmission, data sharing, and screen sharing.

[0010] Furthermore, the mounting and fixing mechanism includes a mounting bracket, with connecting parts on both the top and bottom sides of the mounting bracket. The middle part of the mounting bracket is provided with multiple mounting holes and a positioning circular hole. A wall-adjusting knob is rotatably connected to the rear corner of the mounting bracket.

[0011] Through the above technical solution, the mounting and fixing mechanism is mainly used for supporting and fixing the whiteboard body. During use, the whiteboard body needs to be stably fixed between multiple connecting parts. In addition, multiple mounting holes are opened in the middle of the mounting bracket, so as to facilitate quick fixing with screws and the mounting adjustment mechanism. The rear corners of the mounting bracket are all rotatably connected to the wall-mounting adjustment knobs. When the whiteboard body needs to be adjusted to use in landscape or portrait mode, after the adjustment is completed, the support state between the corners of the mounting bracket and the wall can be adjusted using multiple wall-mounting adjustment knobs to ensure the stability and reliability of the whiteboard body during use, and to prevent shaking or wobbling.

[0012] Furthermore, all of the aforementioned connecting parts are fixedly connected to the whiteboard body by screws.

[0013] The above technical solution not only facilitates quick installation and fixation, ensuring the firmness and stability of the connection, but also facilitates quick disassembly and repair in case of failure.

[0014] Furthermore, the installation and adjustment mechanism includes a fixed plate fixed to the wall, a positioning shaft provided at the center of the front end of the fixed plate, a rotating bearing sleeved on the positioning shaft, an installation plate installed on the outer side of the rotating bearing, four fixed magnetic disks embedded on the periphery of the front end face of the fixed plate, and four corresponding rotating magnetic disks embedded on the rear end face of the installation plate.

[0015] Through the above technical solution, the installation and adjustment mechanism is mainly used to connect and fix the entire whiteboard to the wall. It also facilitates the adjustment and switching of the whiteboard between landscape and portrait modes. During installation, the fixing plate needs to be stably fixed to the wall or other mounting surface using multiple expansion screws. The mounting plate is fixed on the mounting bracket. Since there is a rotating bearing between the fixing plate and the mounting plate, the two can rotate freely, which makes it convenient for operators to adjust the usage state of the whiteboard according to actual needs.

[0016] Furthermore, both the fixed magnetic disk and the rotating magnetic disk are arranged in a cross shape.

[0017] Through the above technical solution, the fixed magnetic disks and rotating magnetic disks arranged in a cross shape have a fixed-point magnetic attraction function. When it is necessary to adjust the usage state of the whiteboard body, the mounting bracket can be directly pried open and rotated around the positioning axis. The whiteboard body can be adjusted within a range of 90 degrees to the left and right. When the adjustment is in place, the fixed magnetic disks and rotating magnetic disks at the corresponding positions will magnetically attract and fix each other, thereby locking the state of the whiteboard body. By using multiple sets of fixed magnetic disks and rotating magnetic disks to fix each other, it is not only convenient to adjust the angle, but also easy to quickly fix and position, thus ensuring flexibility in actual use.

[0018] Furthermore, the sliding support mechanism includes a sliding bracket fixed to the whiteboard body or the mounting and fixing mechanism, and a through sliding guide rail is provided in the middle of the sliding bracket.

[0019] Through the above technical solution, the sliding bracket mainly serves as a support structure, which is used for the sliding support of the rotating support mechanism and the auxiliary whiteboard. When the auxiliary whiteboard is needed, it can be pulled horizontally to allow the corresponding rotating support mechanism to slide on the two sliding brackets, thereby allowing the auxiliary whiteboard to be horizontally unfolded from the rear end of the whiteboard body. When it is not needed, it can simply be pushed back.

[0020] Furthermore, the rotating support mechanism includes a rotating support frame, with limiting sliders at the top and bottom of the rotating support frame, and limiting pulleys installed on both limiting sliders. The two limiting pulleys are respectively slidably limited within the corresponding sliding guide rails, and a mounting slot is provided on one side of the rotating support frame.

[0021] Through the above technical solution, the rotating support mechanism is mainly used to assist in the installation and fixation of the whiteboard. The rotating support frame is perpendicular to the two sliding brackets. Since the two limiting pulleys are respectively limited to the corresponding sliding guide rails, the rotating support mechanism and the entire auxiliary whiteboard can slide freely on the two sliding brackets, ensuring stability and reliability during the sliding process. At the same time, the auxiliary whiteboard can also rotate in the mounting slot, which makes it convenient for operators to adjust the display angle of the auxiliary whiteboard according to actual needs.

[0022] Furthermore, the auxiliary whiteboard includes a support plate rotatably connected to the mounting slot. The front end of the support plate has a lifting slide groove, and both sides of the lifting slide groove have limit slide grooves. An IoT synchronous whiteboard is slidably connected in the lifting slide groove. The bottom of the IoT synchronous whiteboard has a storage slot. One side of the rear end of the support plate has a handle slot, and the other side of the rear end of the support plate has a wire hole. The rear end of the IoT synchronous whiteboard has a data interface for connecting a data cable.

[0023] Through the above technical solution, the auxiliary whiteboard serves as an auxiliary writing mechanism. The text and images written by the operator on the IoT synchronous whiteboard can be synchronously displayed on the main display screen through data transmission. This is convenient for operation and ensures that the display of text and images is not affected by the operator's position, thus guaranteeing the presentation effect. In addition, the front end of the support plate has a lifting slide, which allows the IoT synchronous whiteboard to be freely raised and lowered within the slide. For operators of different heights, it can be flexibly adjusted according to their actual needs, thereby ensuring the smoothness of operation throughout the presentation and explanation process, while also reducing the fatigue intensity of the operator during use, eliminating the need for tiptoeing or bending over.

[0024] Furthermore, the auxiliary support mechanism includes a storage groove at the rear end of the support plate, an auxiliary bracket is rotatably connected in the storage groove, and a silicone pad is installed at the end of the auxiliary bracket away from the hinge point.

[0025] With the above technical solution, in order to ensure the stability of the auxiliary whiteboard during use and prevent it from shaking, the auxiliary bracket can be opened during use so that the silicone pad at the rear of the auxiliary bracket can fit against the wall. The auxiliary bracket can then provide auxiliary support for the auxiliary whiteboard, thus ensuring that the auxiliary whiteboard will not shake or vibrate during writing or touching.

[0026] The beneficial effects of the present invention are as follows: (1) By designing a variety of flexible and adjustable multi-functional adjustment mechanisms, the present invention enables the smart whiteboard to have a better display function and can also be used by operators of different heights and operating habits, thus significantly improving its overall applicability and usability; (2) By designing a sliding support mechanism and a rotating support mechanism, the present invention can easily unfold or store the auxiliary whiteboard, and the auxiliary whiteboard can also rotate in the mounting slot, thus making it convenient for operators to adjust the display angle of the auxiliary whiteboard according to actual needs to adapt to the viewing of people in different positions; (3) By designing a multi-functional auxiliary whiteboard, the present invention enables operators to use the Internet of Things (IoT) The text and images written on the synchronous whiteboard can be synchronously displayed on the main display screen through data transmission, which is convenient to operate and will not affect the display of text and images due to the operator's position; at the same time, the IoT synchronous whiteboard can be freely raised and lowered in the lifting slide, and operators of different heights can be flexibly adjusted according to their actual needs, thereby ensuring the smoothness of operation during the entire presentation and explanation process; (4) By designing the installation and fixing mechanism and the installation and adjustment mechanism, this invention can not only achieve stable installation and fixing of the smart whiteboard, but also quickly realize the free adjustment and switching between horizontal and vertical screens according to actual needs, so as to facilitate the display of different formats of content.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 and not intended to limit the invention.

[0045] like Figures 1-16As shown in the figure, an IoT smart whiteboard of this embodiment includes a whiteboard body 1, which includes a main display screen 101. A smart camera recognition module 102 is provided at the top front end of the main display screen 101, and an operation component 103 is fixedly connected to the bottom of the main display screen 101. The operation component 103 is provided with a switch module 104 and a data external module 105, and a power cord 106 is connected to the rear end of the operation component 103. The main display screen 101 is a large-size industrial-grade LCD screen that uses infrared sensing technology. In conjunction with the smart camera recognition module 102, it supports functions such as handwriting, multi-touch, gesture recognition, and voice recognition, making it convenient for operators to use in actual use. At the same time, the operation component 103 at the bottom of the main display screen 101 allows operators to quickly connect to various types of data terminals to realize functions such as data transmission, data sharing, and screen sharing.

[0046] Regarding the installation and fixing mechanism 2, please refer to... Figures 1-11 The whiteboard body 1 has a mounting mechanism 2 fixedly installed at its rear end for securing the whiteboard. The mounting mechanism 2 includes a mounting bracket 201, with connecting parts 202 on both the top and bottom sides. The middle section of the mounting bracket 201 has multiple mounting holes 203 and a positioning hole 204. Wall-mounting adjustment knobs 205 are rotatably connected to the rear corners of the mounting bracket 201. The mounting mechanism 2 is mainly used for supporting and securing the whiteboard body 1. During use, the whiteboard body 1 needs to be stably fixed to the multiple connecting parts. Between parts 202, in addition, multiple mounting holes 203 are provided in the middle of the mounting bracket 201, so as to facilitate quick fixation with screws and mounting adjustment mechanism 3; the rear corners of the mounting bracket 201 are rotatably connected to wall-mounted adjustment knobs 205. When the whiteboard body 1 needs to be adjusted to use in landscape or portrait mode, after the adjustment is completed, the support state between the corners of the mounting bracket 201 and the wall can be adjusted by using multiple wall-mounted adjustment knobs 205 to ensure the stability and reliability of the whiteboard body 1 during use, and to prevent shaking or wobbling.

[0047] In this embodiment, multiple connecting parts 202 are fixedly connected to the whiteboard body 1 by screws, which not only facilitates quick installation and fixation, ensuring the firmness and stability of the connection, but also facilitates quick disassembly and repair in case of failure.

[0048] Regarding the installation and adjustment mechanism 3, please refer to... Figures 15-16The installation and fixing mechanism 2 has an installation adjustment mechanism 3 installed at the rear center. The rear end of the installation adjustment mechanism 3 is fixed to the wall. The installation adjustment mechanism 3 includes a fixing plate 301 fixed to the wall. The front center of the fixing plate 301 has a positioning shaft 302. A rotating bearing 303 is sleeved on the positioning shaft 302. An installation plate 304 is installed on the outside of the rotating bearing 303. Four fixed magnetic disks 305 are embedded in the periphery of the front surface of the fixing plate 301. Four corresponding rotating magnetic disks 306 are embedded in the rear surface of the installation plate 304. The installation adjustment mechanism 3 is mainly used for connecting and fixing the entire whiteboard to the wall. It also facilitates the adjustment and switching of the whiteboard between horizontal and vertical screens. During installation, the fixing plate 301 needs to be stably fixed to the wall or other mounting surface using multiple expansion screws. The installation plate 304 is fixed to the mounting bracket 201. Since the rotating bearing 303 is installed between the fixing plate 301 and the installation plate 304, the two can rotate freely, which makes it convenient for the operator to adjust the usage state of the whiteboard body 1 according to actual needs.

[0049] In this embodiment, both the fixed magnetic disk 305 and the rotating magnetic disk 306 are arranged in a cross shape. The fixed magnetic disk 305 and the rotating magnetic disk 306 arranged in a cross shape have a fixed-point magnetic attraction function. When it is necessary to adjust the usage state of the whiteboard body 1, the mounting bracket 201 can be directly bent and rotated around the positioning shaft 302 as the axis. The whiteboard body 1 can be adjusted within a range of 90 degrees to the left and right. When the adjustment is in place, the fixed magnetic disk 305 and the rotating magnetic disk 306 at the corresponding positions will be magnetically attracted to each other and fixed, thereby locking the state of the whiteboard body 1. By using multiple sets of fixed magnetic disks 305 and rotating magnetic disks 306 to be fixed by mutual magnetic attraction, it is not only convenient to adjust the angle, but also easy to quickly achieve fixation and positioning, thus ensuring flexibility in actual use.

[0050] Regarding sliding support mechanism 4, refer to... Figures 1-13 A set of horizontally arranged sliding support mechanisms 4 are fixedly installed on the rear end face of the whiteboard body 1 and the mounting and fixing mechanism 2. The sliding support mechanism 4 includes a sliding bracket 401 fixed to the whiteboard body 1 or the mounting and fixing mechanism 2. A through sliding guide rail 402 is provided in the middle of the sliding bracket 401. The sliding bracket 401 mainly serves as a support structure, which is used for the sliding support of the rotating support mechanism 5 and the auxiliary whiteboard 6. When the auxiliary whiteboard 6 is needed, it can be pulled horizontally, so that the corresponding rotating support mechanism 5 can slide on the two sliding brackets 401, thereby allowing the auxiliary whiteboard 6 to be horizontally unfolded from the rear end of the whiteboard body 1. When it is not needed, it can simply be pushed back.

[0051] Regarding the rotary support mechanism 5, refer to... Figures 12-14Two sets of sliding support mechanisms 4 are each slidably mounted with a rotating support mechanism 5. The rotating support mechanism 5 includes a rotating support frame 501. The top and bottom of the rotating support frame 501 are provided with limiting sliders 502, and each of the two limiting sliders 502 is equipped with a limiting pulley 503. The two limiting pulleys 503 are respectively slidably limited within the corresponding sliding guide rails 402. A mounting slot 504 is opened on one side of the rotating support frame 501. The rotating support mechanism 5 is mainly used to assist in the installation and fixation of the whiteboard 6. The rotating support frame 501 is perpendicular to the two sliding supports 401. Since the two limiting pulleys 503 are respectively slidably limited within the corresponding sliding guide rails 402, the rotating support mechanism 5 and the entire auxiliary whiteboard 6 can slide freely on the two sliding supports 401, ensuring stability and reliability during the sliding process. At the same time, the auxiliary whiteboard 6 can also rotate within the mounting slot 504, so that the operator can easily adjust the display angle of the auxiliary whiteboard 6 according to actual needs.

[0052] Regarding the auxiliary whiteboard 6, please refer to... Figures 1-10 Each of the two sets of rotating support mechanisms 5 is rotatably connected to an auxiliary whiteboard 6. Supported by the sliding support mechanism 4 and the rotating support mechanism 5, the two sets of auxiliary whiteboards 6 can slide open and retract. Each auxiliary whiteboard 6 includes a support plate 601 rotatably connected to a mounting slot 504. A lifting slide groove 602 is provided at the front end of the support plate 601, and limit slide grooves 603 are provided on both sides of the lifting slide groove 602. An IoT synchronous whiteboard 604 is slidably connected within the lifting slide groove 602. A storage slot 605 is provided at the bottom of the IoT synchronous whiteboard 604. A handle groove 606 is provided on one side of the rear end of the support plate 601, and a cable threading hole 607 is provided on the other side of the rear end of the IoT synchronous whiteboard 604. A data interface for connecting a data cable is provided at the rear end of the IoT synchronous whiteboard 604. The auxiliary whiteboard 608 serves as an auxiliary writing mechanism. The text and images written by the operator on the IoT synchronous whiteboard 604 can be synchronously displayed on the main display screen 101 via data transmission. This facilitates operation and ensures that the display of text and images is not affected by the operator's position, thus guaranteeing the presentation effect. In addition, the front end of the support plate 601 is provided with a lifting slide 602, which allows the IoT synchronous whiteboard 604 to be freely raised and lowered within the lifting slide 602. For operators of different heights, it can be flexibly adjusted according to their actual needs, thereby ensuring the smoothness of operation during the entire presentation and explanation process, while also reducing the fatigue intensity of the operator during use, eliminating the need for tiptoeing or bending over.

[0053] Regarding auxiliary support mechanism 7, please refer to... Figures 1-8Both sets of auxiliary whiteboards 6 are rotatably connected to an auxiliary support mechanism 7 at their rear ends. The auxiliary support mechanism 7 includes a storage slot 701 opened at the rear end of the support plate 601. An auxiliary bracket 702 is rotatably connected in the storage slot 701. A silicone pad 703 is installed at the end of the auxiliary bracket 702 away from the hinge point. In order to ensure the stability of the auxiliary whiteboard 6 during use and prevent it from shaking, the auxiliary bracket 702 can be opened during use so that the silicone pad 703 at the rear end of the auxiliary bracket 702 can be attached to the wall. The auxiliary bracket 702 is used to provide auxiliary support for the auxiliary whiteboard 6, thereby ensuring that the auxiliary whiteboard 6 will not shake or vibrate during writing or touching.

[0054] The working principle of this embodiment is as follows: When in use, first connect the power cord 106 to the power supply, and then turn on the main display screen 101 through the switch module 104. The main display screen 101 is provided with an operation component 103 at the bottom, and the operation component 103 is provided with a data external module 105. Operators can quickly connect to various types of data terminals to realize functions such as data transmission, data sharing and screen sharing. During the display process, the display content of the main display screen 101 can be controlled by handwriting, multi-touch, gesture recognition, voice recognition and other methods.

[0055] When the main display screen 101 needs to be adjusted to portrait mode, the mounting bracket 201 can be bent directly and rotated around the positioning axis 302. The whiteboard body 1 can be adjusted within a range of 90 degrees to the left and right. When the adjustment is in place, the fixed magnetic disk 305 and the rotating magnetic disk 306 at the corresponding positions will be magnetically attracted to each other, thereby locking the state of the whiteboard body 1.

[0056] When the auxiliary whiteboard 6 is needed, it can be pulled horizontally to allow the corresponding rotating support mechanism 5 to slide on the two sliding brackets 401, thereby allowing the auxiliary whiteboard 6 to unfold horizontally from the rear end of the whiteboard body 1. At the same time, the auxiliary whiteboard 6 can also rotate within the mounting slot 504, so that the operator can adjust the display angle of the auxiliary whiteboard 6 according to actual needs.

[0057] As an auxiliary writing mechanism, the auxiliary whiteboard 6 allows the text and graphics written by the operator on the IoT synchronous whiteboard 604 to be synchronously displayed on the main display screen 101 via data transmission. At the same time, the display of text and graphics information will not be affected by the operator's position, thus ensuring the display effect. In addition, the front end of the support plate 601 is provided with a lifting slide 602, which allows the IoT synchronous whiteboard 604 to be freely raised and lowered within the lifting slide 602. For operators of different heights, it can be flexibly adjusted according to their actual needs, thus ensuring the smoothness of operation throughout the entire presentation and explanation process.

[0058] Both sets of auxiliary whiteboards 6 are rotatably connected to auxiliary support mechanisms 7 at their rear ends. When in use, the auxiliary brackets 702 can be opened so that the silicone pads 703 at the rear end of the auxiliary brackets 702 can fit against the wall. The auxiliary brackets 702 can then provide auxiliary support for the auxiliary whiteboards 6, thus ensuring that the auxiliary whiteboards 6 will not shake or vibrate during writing or touching.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
