Detailed Description
In order to reduce the problem that the edge of the plate body of the auxiliary blackboard cuts a user. The embodiment of the invention provides a sub-blackboard and an intelligent blackboard. In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the following embodiments.
Fig. 1 is a schematic structural view of an auxiliary blackboard according to an embodiment of the present invention, and as shown in fig. 1, an intelligent blackboard is formed by the auxiliary blackboard provided in an embodiment of the present invention and a main screen, the auxiliary blackboard being installed at an edge of the main screen. The auxiliary blackboard comprises a board body 1, a backboard 2 and a guard 3. The backboard 2 includes a backboard body 21 and a support portion 22. The supporting portion 22 is located at the edge of the backboard body 21 and perpendicular to the backboard body 21, and the supporting portion 22 is used for supporting the board body 1. The plate body 1 is mounted on one end of the support portion 22 away from the backboard body 21. The protecting piece 3 covers the edge of the plate body 1, and the protecting piece 3 is used for shielding the edge of the plate body 1, so that the user is prevented from being cut by the edge of the plate body 1.
In the above embodiment, the support portion 22 supports the plate body 1, and thus the plate body 1 can be less bent. The plate body 1 is manufactured by adopting a cutting and forming process method, so the edge is sharp. The protective part 3 covers the sharp edge, so that the situation that a user is cut can be reduced.
In an alternative embodiment, the supporting portion 22 may include a supporting body 221 and a supporting plate 222, and the supporting plate 222 is located on a side of the supporting body 221 away from the backboard body 21 and is parallel to the backboard body 21. The support plate 222 increases the contact area between the support part 22 and the plate body 1, so that the plate body 1 and the back plate 2 are combined more firmly. When the backboard 2 is slightly deformed by an external force, the contact area between the support plate 222 and the backboard body 1 is large, so that the connection is firm, and the backboard body 1 and the backboard 2 are not easy to be dislocated.
When the back plate 2 is specifically manufactured, the edges of the periphery of the back plate 2 may be bent to form the support body 221, and then the support body 221 may be bent to form the support plate 222. The support part 22 and the backboard 2 are integrated, so that the strength is higher, and the auxiliary blackboard is firmer.
With continued reference to fig. 1, in an alternative embodiment, the side of the plate body 1 facing away from the backing plate 2 is coated with an enamel material to form an enamel layer 4, and the enamel layer 4 can serve as a writing surface. Compared with the baking varnish material in the prior art, the enamel material is more wear-resistant, and the service life of the auxiliary blackboard can be prolonged.
FIG. 2 is a schematic cross-sectional view of an enamel layer in an embodiment of the present invention. With reference to fig. 1 and 2, in an alternative embodiment, the surface of the enamel layer 4 on the side facing away from the plate body 1 is provided with particles 41. The particles 41 are used to cut the chalk so that the chalk can leave the powder on the enamel layer 4 to form a writing trace when writing. The particles 41 make the surface of the enamel layer 4 uneven, increase the friction force between the chalk and the enamel layer 4, and more easily leave writing marks, thereby reducing the slipping condition of the chalk during writing.
Referring to fig. 1, in an alternative embodiment, the sub-blackboard may further include a core material 5, and the core material 5 is installed between the backboard body 21 and the board body 1 to support the middle area of the board body 1. When the size of the plate body 1 is large, the supporting strength by the supporting portion 22 located at the edge of the back plate 2 is insufficient, and the middle area of the plate body 1 is deformed. The deformation of the panel body 1 can be reduced by supporting the core material 5 in the middle region of the panel body 1.
In an alternative embodiment, the thickness of the core material 5 may be the same as the height of the support portion 22, so that after the core material 5 is mounted on the backplane body 21, the support plate 222 and the upper surface of the core material 5 are at the same level, so as to improve the support effect.

As shown in fig. 6, when the support 52 is specifically prepared, the support 52 may have a honeycomb structure. In a specific embodiment, the support body 52 of the honeycomb structure may be specifically: the support body 52 includes a plurality of cylindrical bodies 522, and the plurality of cylindrical bodies 522 are closely arranged to constitute the support body 52.
Specifically, when the material of the core material 5 is selected, a material such as paper, foamed PVC, or aluminum may be selected as the material of the core material 5. The weight of the core material 5 can be made lighter, the whole weight of the auxiliary blackboard is reduced, and the auxiliary blackboard is convenient to install.
With continued reference to fig. 1, in an alternative embodiment, the sub-blackboard may further include a first glue layer 6 and a second glue layer 7. The first adhesive layer 6 is located between the core material 5 and the board body 1, and the second adhesive layer 7 is located between the core material 5 and the back board body 21. The core material 5 is fixed with the plate body 1 and the back plate 2 in a bonding mode, so that the installation is simple and the cost is saved.
With continued reference to fig. 1, when the plate body 1, the core material 5 and the back plate 2 are specifically assembled, the lower surface of the plate body 1 may be coated with a first adhesive layer 6, and the upper surface of the back plate body 21 may be coated with a second adhesive layer 7. The plate body 1 and the back plate 2 are positioned and placed by adopting a jig.
