[0022] It should be further explained that the drawings and implementation modes of the present invention mainly describe the concept of the present invention. On the basis of this concept, some specific forms and settings of connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can implement the above-mentioned specific forms and settings in a well-known manner.

[0023] When an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element.

[0024] The directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself. The directions or positional relationships indicated by the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0025] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below".

[0026] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, and "several" means one or more, unless otherwise clearly and specifically defined.

[0027] The intelligent lifting flat-panel interconnected writing board provided by the utility model is now described.

[0028] like Figures 1 to 3 As shown, one embodiment of the utility model provides an intelligent liftable flat-screen interconnected writing board, including a frame 1 and a plurality of writing boards 2 that slide and lift on the frame 1, sliding members 21 are provided at both ends of the writing boards 2, and a plurality of groups of linear rails 3 are provided in the frame 1 for corresponding sliding members 21 to lift and lower therein; at least one group of linear rails 3 is connected to a track changing rail 4 at its end, and after the sliding member 21 moves to the track changing rail 4, the front of this writing board 2 is flush with the front of the adjacent writing board 2.

[0029] Specifically, in the present embodiment, there are two writing boards 2, and the interior of the frame 1 is divided into three areas: upper, middle and lower. The area of ​​the writing board 2 is consistent with the area of ​​a single area.

[0030] When using the writing board 2, after sliding the linearly lifted writing board 2 to the specified position, slide the writing board 2 with the track change track 4 to lift it up and down, and the sliding member 21 of the writing board 2 enters the track change track 4 from the linear track 3 to realize the front and rear position change of the writing board 2, and the intersection of two adjacent writing boards 2 is flush.

[0031] Compared with the prior art, the intelligent lifting flat-panel interconnected writing board provided in this embodiment has a straight track 3 and a track-changing track 4. When the writing board 2 is slid so that the sliding member 21 enters the track-changing track 4 from the straight track 3, the writing board 2 changes its front and rear position until it is flush with the front of the adjacent writing board 2, making the junction of the adjacent writing boards 2 clearer and more convenient to view, thereby improving the use effect of the writing board 2.

[0032] like Figure 1 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0033] According to the ratio between human body height and the height of the writing board 2, the two writing boards 2 in this embodiment mainly include three states during use. The first state is that the two writing boards 2 are all located in the lower area. At this time, the upper and middle areas are vacant and are mainly used for displaying screens or projections, and no writing is done. The second state is that the two writing boards 2 are respectively located in the middle and lower areas. The writing board 2 located in the lower area is too low to be convenient for writing. At this time, writing is mainly done on the writing board 2 located in the middle area, and the front sides of the two writing boards 2 may not be in a flush state. The third state is that the two writing boards 2 are respectively located in the upper and middle areas. This state is that after the middle writing board 2 in the second state is full, it is raised to the upper area, and the unused writing board 2 in the lower area is raised to the middle area for use in writing. After this state, the front sides of the two writing boards 2 are flush, making the handwriting at the junction of the two writing boards 2 clearer to see.

[0034] like Figure 2 and Figure 4 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0035] The track change track 4 is an arc track, and the frame 1 is provided with a driving mechanism 5 for driving the corresponding writing board 2 to slide. The arc-shaped track change track 4 can make the sliding member 21 enter the track change track 4 from the straight track 3 more smoothly, and the driving mechanism 5 drives instead of manual pushing, thereby improving the operation effect.

[0036] Specifically, in this embodiment, a plurality of sliding members 21 may be provided on both sides of each writing board 2, and pulleys may be used as the sliding members 21 to reduce sliding friction.

[0037] Optionally, in another modified embodiment, the angle between the track-changing track 4 and the linear track 3 can be a right angle. In this modified embodiment, the driving mechanism 5 is not used. For manual lifting, a handle is installed at the front edge of the writing board 2 with the track-changing track 4. After the sliding member 21 on the writing board 2 is manually slid to the end of the linear track 3, the handle is pulled forward or the writing board 2 is pressed backward to make the sliding member 21 enter the track-changing track 4 to achieve the coplanarity of the two writing boards 2. This modified embodiment can reduce the overall cost on the basis of achieving the coplanarity function of the two lifting writing boards 2.

[0038] like Figures 4 to 5 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0039] The driving mechanism 5 includes a driving member 51, two groups of balancing components 52 and two groups of counterweights 53. The two groups of balancing components 52 are respectively located on the frame 1 at both ends of the writing board 2; one end of the balancing component 52 is connected to the writing board 2, and the other end of the balancing component 52 is connected to the counterweight 53; the writing board 2 and the counterweight 53 have the same weight, and the balancing component 52 is used to maintain the balance between the writing board 2 and the counterweight 53; the driving member 51 is set on the frame 1 and connected to one of the groups of balancing components 52, and the driving member 51 is used to break the balance between the writing board 2 and the counterweight 53.

[0040] When it is necessary to raise or lower the writing board 2, the balance of the single balancing component 52 is broken by the driving member 51, driving the writing board 2 to rise or fall, and the counterweight block 53 follows the descent or rise. At the same time, the counterweight block 53 located at the other end of the writing board 2 automatically drives the writing board 2 to rise or fall through the balancing component 52. Each writing board 2 only needs to install the driving member 51 at one end, and the stable lifting of the other end of the writing board 2 can also be achieved, and the problem of one end of the writing board 2 rising and the other end failing to follow is avoided.

[0041] like Figures 4 to 5 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0042] The balancing assembly 52 includes a sprocket 521 and a chain 522. The sprocket 521 is arranged on the top of the frame 1 and connected to the driving member 51. The chain 522 is engaged with the sprocket 521. One end of the chain 522 is connected to the writing board 2, and the other end of the chain 522 is connected to the counterweight 53. The sprocket 521 is the fulcrum.

[0043] Optionally, in this embodiment, the balancing component 52 may also connect the writing board 2 and the counterweight 53 by means of a rope and a pulley, and the pulley is the fulcrum.

[0044] Specifically, in this embodiment, the driving member 51 is a motor, the driving member 51 body is fixed on the top of the frame 1, and the output shaft of the driving member 51 is coaxially fixed with the sprocket 521 or the pulley.

[0045] When the writing board 2 needs to be raised or lowered, the driving member 51 is started to rotate the sprocket 521 or the pulley, and the sprocket 521 or the pulley drives the chain 522 or the rope to realize stable raising and lowering of both ends of the writing board 2.

[0046] Optionally, in this embodiment, the computer can be used to perform signal control on the driving members 51 that respectively drive the two writing boards 2 to rise and fall, and the three states of the writing board 2 can be switched during use by manual buttons or computer operations, further improving ease of use.

[0047] like Figure 4 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0048] The chain 522 and the writing board 2, and the chain 522 and the counterweight 53 are all detachably connected. Specifically, in this embodiment, the chain 522 and the writing board 2, and the chain 522 and the counterweight 53 can be detachably connected through a hook and a ring, a bolt and a nut, or a transverse insertion rod. It is convenient to equip the counterweight 53 with different weights according to the writing board 2 of different weights.

[0049] like Figure 1 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0050] A chalk groove (not shown) is provided inside the frame 1, and the chalk groove is not on the sliding track of the writing board 2. Specifically, in this embodiment, the chalk groove is arranged behind the two writing boards 2, and the chalk groove is located in the lower area of ​​the frame 1 near the middle area, which is more convenient to use in combination with the three states of the writing board 2 when in use.
