[0030] It should be noted that, when in use, the soft magnetic blackboard body 10 is adsorbed on the blackboard, and the teacher can write words on the grid area 1011 or write letters on the letter area 1012, and the letter area 1012 is composed of three equidistant horizontal grids.

[0031] Furthermore, in order to prevent the soft magnetic blackboard body 10 from wrinkling and causing inconvenience in writing, Figure 2As shown, the framed soft magnetic blackboard also includes a frame assembly 20, which is located on the outside of the soft magnetic blackboard body 10, and the frame assembly 20 is connected to the four sides of the soft magnetic blackboard body 10, and the frame assembly 20 is made of hard material, such as hard plastic.

[0032] It should be noted that, by connecting the four sides of the flexible soft magnetic blackboard body 10 to the frame assembly 20, the soft magnetic blackboard body 10 is in a straight state and is not easy to wrinkle under the action of external force. Compared with the prior art, it has the advantage of not being easy to wrinkle.

[0033] It should also be noted that in the prior art, since the soft magnetic blackboard body 10 is an integrated design, the grid area 1011 and the letter area 1012 need to be displayed at the same time. Therefore, when practicing letters in English class, the grid area 1011 located above the letter area 1012 appears abrupt and occupies blackboard space.

[0034] In view of this, in the embodiments of the present application, Figure 2 As shown, the soft magnetic blackboard body 10 includes two soft magnetic blackboard structures 101, one of the soft magnetic blackboard structures 101 has the grid area 1011, and the other soft magnetic blackboard structure 101 has the letter area 1012, the frame assembly 20 includes a first frame 201 and a second frame 202, one side of the first frame 201 and the second frame 202 has an opening 2014, the opening 2014 makes the first frame 201 and the second frame 202 U-shaped, the first frame 201 and the second frame 202 are hinged to each other on one side of the opening 2014, the three sides of one soft magnetic blackboard structure 101 are connected to the first frame 201, and the three sides of the other soft magnetic blackboard structure 101 are connected to the second frame 202.

[0035] It should be noted that, by splitting the soft magnetic blackboard body 10 into two soft magnetic blackboard structures 101, and splitting the frame assembly 20 into the first frame 201 and the second frame 202, and making the first frame 201 rotatably connected to the second frame 202, when only the letter area 1012 is needed, or when storing, the first frame 201 and the second frame 202 can be folded to display only the letter area 1012 and reduce the space occupied. Compared with the prior art, it has the advantage of easy storage.

[0036] Furthermore, in order to realize the connection between the soft magnetic blackboard structure 101 and the first frame 201 or the second frame 202, as Figure 2 and Figure 3As shown, the three sides of the first frame 201 and the second frame 202 have a through connection groove 2011, and the three sides of each soft magnetic blackboard structure 101 have an extension portion 1013, each of the extension portions 1013 extends into the corresponding connection groove 2011, and the extension portion 1013 is adhesively connected to the groove wall of the connection groove 2011.

[0037] Specifically, in order to allow the glue to fully fill the groove surface of the extension portion 1013 and the connecting groove 2011, as shown in FIG. Figure 2 and Figure 3 As shown, the first frame 201 and the second frame 202 have three sides of the connection groove 2011 and also have a glue injection groove 2012 , the glue injection groove 2012 is vertically arranged with the connection groove 2011 , and the glue injection groove 2012 is connected with the connection groove 2011 .

[0038] Furthermore, in order to achieve that the two soft magnetic blackboard structures 101 can be completely overlapped, as Figure 5 and Figure 6 As shown, the side ends of the first frame 201 and the second frame 202 located on both sides of the opening 2014 are arc surfaces, and the first frame 201 and the second frame 202 have a slide groove 2013 in the thickness direction, and the frame assembly 20 also includes a first sliding member 203 and a second sliding member 204, one end of the first sliding member 203 and the second sliding member 204 has a boss 2031, each of the slide grooves 2013 is slidably provided with a boss 2031, and the ends of the first sliding member 203 and the second sliding member 204 away from the boss 2031 are hinged to each other after bending at a predetermined angle, and when the first sliding member 203 and the second sliding member 204 slide a predetermined distance, refer to Figure 5 and Figure 7 The ends of the first sliding member 203 and the second sliding member 204 facing away from the boss 2031 are flush with the back side of the soft magnetic blackboard structure 101 or extend out of the back side of the soft magnetic blackboard structure 101 by a predetermined distance.

[0039] It should be noted that, refer to Figure 5 and Figure 7When it is necessary to simultaneously adsorb the two soft magnetic blackboard structures 101 to the external blackboard, the ends of the first sliding member 203 and the second sliding member 204 that are away from the boss 2031 are flush with the back of the soft magnetic blackboard structure 101 to ensure the flatness of the two soft magnetic blackboard structures 101. When it is necessary to fold the two soft magnetic blackboard structures 101, the ends of the first sliding member 203 and the second sliding member 204 that are away from the boss 2031 are extended out of the back of the soft magnetic blackboard structure 101 by a predetermined distance, and the central axis of the hinge between the first sliding member 203 and the second sliding member 204 is flush with the back of the soft magnetic blackboard structure 101. At this time, the first frame 201 can be flipped.
