[0012] In one possible implementation of the intelligent sliding blackboard for preventing cable tangling provided by this utility model, the automatic cable winder is disposed within the limiting frame and connected to the limiting frame, and the mounting frame further includes:

[0013] The four corner frames are the four corners of the mounting frame, and each corner frame is connected to one end of the limiting frame and one end of the guide frame.

[0014] A guide roller is located inside the corner frame and connected to the corner frame. The connecting wire extending from the automatic winding device passes through the guide roller and enters the guide frame.

[0037] Please refer to the following: Figures 1 to 6 The present invention provides an intelligent sliding blackboard with anti-tangling connector wires. The intelligent sliding blackboard with anti-tangling connector wires includes a mounting frame, a blackboard 20, an automatic wire winder 30, and a connector wire 40. The mounting frame has two limiting frames 11 and two guide frames 12. The two guide frames 12 are parallel and spaced apart. The two limiting frames 11 are parallel and respectively located at both ends of the guide frames 12, forming a rectangular frame. The blackboard 20 is located between the two guide frames 12 and slides with them. The automatic wire winder 30 is located inside the limiting frames 11 or guide frames 12 and is connected to them. The connector wire 40 is wound inside the automatic wire winder 30, with one end being a fixed end and the other a retractable end. The retractable end is inserted into the blackboard 20 and moves with it. The fixed end is fixedly set and used to connect to external devices, such as all-in-one machines, computers, power supply equipment, etc.

[0038] It should be noted that the blackboard 20 is the existing infrared smart blackboard 20, which can synchronize the written content on the blackboard 20 to designated electronic devices such as computers and all-in-one machines via data cable.

[0039] The connecting cable 40 can be a power cable, data cable, or a data cable with power supply function, used to supply power or transmit data. Both the retractable end and the fixed end of the connecting cable 40 are equipped with plugs, and the blackboard 20 has corresponding interfaces for connecting to the plugs of the retractable end of the connecting cable 40. The plug of the fixed end of the connecting cable 40 is connected to the interface of an external device (such as an all-in-one computer, a computer, or a power supply device) to realize data transmission and power supply between the blackboard 20 and the external device.

[0040] The automatic cable winder 30 is an existing device; specifically, the automatic cable winder 30 is a self-rebound cable winder with a spring. Furthermore, the tension applied by the automatic cable winder 30 to the connecting cable 40 is less than the sliding resistance of the blackboard 20.

[0041] The beneficial effects of the intelligent sliding blackboard with anti-tangling connection cable provided by this utility model are as follows: Compared with the prior art, the intelligent sliding blackboard with anti-tangling connection cable provided by this utility model has an automatic cable winder 30 that automatically winds up and unwinds the connection cable 40 as the blackboard 20 slides, maintaining the synchronous movement of the connection cable 40 and the blackboard 20; that is, when the blackboard 20 moves away from the automatic winder, the automatic winder releases the connection cable 40 under the drag of the blackboard 20, and when the blackboard 20 moves closer to the automatic winder, the automatic winder automatically retracts the connection cable 40, so that the length of the connection cable 40 extending out of the automatic winder matches the distance between the blackboard 20 and the automatic winder, thereby effectively avoiding problems such as data cable damage and scattering, and ensuring a stable connection between the blackboard 20 and external devices.

[0042] like Figure 3 and Figure 6 As shown, in a specific embodiment of the intelligent sliding blackboard with anti-tangling connecting wires provided in this utility model embodiment, a limiting plate 60 is also included. The limiting plate 60 is connected to the side of the blackboard 20 facing the guide frame 12. The limiting plate 60 is provided with a limiting hole, and the telescopic end of the connecting wire 40 passes through the limiting hole and is inserted into the blackboard 20.

[0043] Specifically, the limiting plate 60 is located on the side of the blackboard 20 facing the guide frame 12 through which the connecting wire 40 passes, and is fixedly connected to the blackboard 20. The connecting wire 40 passes through the limiting hole on the limiting plate 60 and is plugged into the corresponding connector on the blackboard 20, thereby limiting the position of the connecting wire 40 relative to the blackboard 20.

[0044] Furthermore, such as Figure 3 and Figure 6 As shown, in a specific embodiment of the intelligent sliding blackboard with anti-tangling connection wire provided in this utility model, a fixing member is also included. The fixing member is connected to the limiting plate 60 and is used to fix the connection wire 40 on the limiting plate 60 to prevent the connection wire 40 from being loosened due to tension at the insertion position of the blackboard 20.

[0045] Specifically, such as Figure 3 and Figure 6 As shown, in a specific embodiment of the intelligent sliding blackboard for preventing tangling of connecting wires provided in this utility model, the fixing component includes an R-shaped wire clamp 71 and a fastener 72. The R-shaped wire clamp 71 is disposed on the upper side of the limiting plate 60 and clamps the connecting wire 40. The fastener 72 passes through the R-shaped wire clamp 71 and connects to the limiting plate 60, fixing the R-shaped wire clamp 71 on the limiting plate 60.

[0046] It should be noted that the R-type wire clamp 71 is interference-fitted with the connecting wire 40, and the frictional resistance between the R-type wire clamp 71 and the connecting wire 40 is greater than the pulling force of the automatic cable reel 30 on the connecting wire 40, so as to achieve relative fixation of the connecting wire 40. The fastener 72 is a screw, bolt, rivet, etc. Preferably, the fastener 72 is a pop rivet.

[0047] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown in the embodiment of the intelligent sliding blackboard for preventing tangling of connecting wires provided in this utility model, the automatic wire winder 30 is disposed inside the limiting frame 11 and connected to the limiting frame 11. The mounting frame also includes four corner frames 13 and guide rollers 50. The four corner frames 13 are respectively installed at the four corners of the frame, and each corner frame 13 is respectively connected to one end of the limiting frame 11 and one end of the guide frame 12. The guide rollers 50 are disposed inside the corner frames 13 and connected to the corner frames 13. The connecting wire 40 extending from the automatic wire winder 30 passes through the guide rollers 50 and enters the guide frame 12.

[0048] It should be noted that the corner ends of the mounting frame are the most vulnerable parts of the entire frame system, most susceptible to bumps and damage. Corner frame 13, as a separate, more robust component, wraps around or fits into this joint, forming a physical protective layer; and corner frame 13 provides a precise reference point. During installation, corner frame 13 is first fixed to the wall or supporting structure, or the two frame sections are first connected and fixed using corner frame 13, and then the entire frame is installed. This method makes it easier to control diagonal and angular accuracy (90 degrees), avoiding the cumulative errors caused by minor deviations when directly splicing the frame, which could lead to overall frame deformation or installation difficulties.

[0049] The rollers can effectively guide and change the direction of movement of the connecting wire 40, thereby allowing the automatic winding device 30 to be placed in a larger space, such as within the limiting frame 11.

[0050] like Figure 3 and Figure 3As shown in the embodiment of the intelligent sliding blackboard for preventing tangling of connecting wires provided in this utility model, the surface of the guide roller 50 is provided with an anti-slip rubber layer to increase the friction with the connecting wire 40 and prevent the connecting wire 40 from frequently slipping on the guide roller 50 and wearing out the connecting wire 40.

[0051] like Figures 1 to 3 As shown, in a specific embodiment of the intelligent sliding blackboard for preventing tangling of connecting wires provided in this utility model, two guide frames 12 are arranged horizontally, and two limiting frames 11 are arranged vertically.

[0052] There are two blackboards 20, two automatic cable winders 30, and two connecting cables 40. The two blackboards 20 are staggered and slide with the guide frame 12, which is suitable for sliding left and right along the guide frame 12. The two automatic cable winders 30 are connected to the limiting frame 11 or the guide frame 12. The two connecting cables 40 are respectively wound into the two automatic cable winders 30, and the telescopic ends of the two connecting cables 40 are respectively connected to the two blackboards 20.

[0053] Specifically, in this embodiment, the intelligent sliding blackboard with anti-tangling connecting wires is a left-right push-pull type blackboard 20. The automatic wire winder 30 is fixedly installed inside the limiting frame 11, and the connecting wire 40 passes through the guide frame 12 located on the lower side. The telescopic end is inserted into the blackboard 20 and moves synchronously with the blackboard 20.

[0054] like Figures 4 to 6 As shown, in a specific embodiment of the intelligent sliding blackboard for preventing tangling of connecting wires provided in this utility model, two guide frames 12 are arranged vertically and two limiting frames 11 are arranged horizontally.

[0055] There are two blackboards 20, two automatic cable winders 30, and two connecting cables 40. The two blackboards 20 are staggered and slide with the guide frame 12, which is suitable for sliding up and down along the guide frame 12. The two automatic cable winders 30 are connected to the limiting frame 11 or the guide frame 12. The two connecting cables 40 are respectively wound into the two automatic cable winders 30, and the telescopic ends of the two connecting cables 40 are respectively connected to the two blackboards 20.

[0056] Specifically, in this embodiment, the intelligent sliding blackboard with anti-tangling connecting wires is a vertically lifting blackboard 20. The automatic wire winder 30 is fixedly installed inside the lower limiting frame 11, and the connecting wire 40 passes through the guide frame 12 located on the left side. The telescopic end is inserted into the blackboard 20 and moves synchronously with the blackboard 20.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
