[0047] The writing whiteboard in the related art has the problem of occupying a large area and being inconvenient to store and transport. The inventor has found that the reason for this problem is that the writing whiteboard is usually configured as a complete rectangular board. In order to increase the writing area, the length of the writing whiteboard is longer, resulting in it occupying a large area and being inconvenient to store and transport.

[0048] In response to the above technical problems, an embodiment of the present application provides a writing whiteboard, which is achieved by splicing two whiteboards using a hinge assembly. The two whiteboards are rotatably connected through the hinge assembly to form a hinge point, and the hinge point is located on the outside of the side of the writing whiteboard. The two whiteboards can be flipped relative to each other so that the writing whiteboard is in an unfolded state or a folded state.

[0049] Furthermore, when the writing whiteboard is in an unfolded state, the two whiteboards are in the same plane, and the joint surfaces of the two whiteboards fit each other, that is, a flat writing surface with no gaps at the joint is formed; and when the writing whiteboard is in a folded state, the plurality of whiteboards at least partially overlap. With such an arrangement, when the writing whiteboard is stored, the two whiteboards can be folded, which reduces the occupied area and facilitates storage, packaging and transportation.

[0050] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0051] To facilitate the description of the writing whiteboard provided in the embodiment of the present application, the coordinate system in the accompanying drawings is first explained, wherein the X-axis direction is the first direction, which may be the width direction of the writing whiteboard, the Y-axis direction is the second direction, which may be the length direction of the writing whiteboard, and the Z-axis direction is the third direction, which may be the thickness direction of the writing whiteboard.

[0052] like Figures 1 to 5 As shown, the writing whiteboard 100 provided in the embodiment of the present application is used for writing on the blackboard in teaching, conference and other scenes to facilitate communication and exchange. The writing whiteboard 100 includes two whiteboards 10 and a hinge assembly 20 connecting the two whiteboards 10, wherein each whiteboard 10 is configured as a rectangular board, and the whiteboard 10 includes a board body 11 and a panel 12, wherein the panel 12 is laid on the surface of the board body 11 and is used for writing.

[0053] For example, the panel 12 may include a magnetic plate or a non-magnetic plate. For example, the magnetic plate includes a substrate and a paint coating. The substrate may be made of a metal plate and can be adsorbed by magnetic force; the paint coating is made of a material that is easy to write on. The non-magnetic plate includes but is not limited to a melamine plate, a ceramic plate, etc., and the embodiments of the present application are not limited thereto.

[0054] Furthermore, the board body 11 may be made of plastic material, wood material, paper material or other materials with a certain hardness. For example, the board body may be a honeycomb board made of paper material, which is not limited in the embodiment of the present application.

[0055] Along the first direction, a group of hinge components 20 are respectively provided on the two bottom surfaces of the two whiteboards 10, and the two whiteboards 10 are rotatably connected by the two hinge components 20, and hinge points are respectively formed. The two hinge points are located on the same straight line, and each hinge point is located on the outer side of the writing whiteboard 100, so that the two whiteboards 10 can be flipped to one side, and, along the second direction, the hinge components 20 do not occupy the space at the joint of the two whiteboards 10.

[0056] like Figure 6 As shown, each whiteboard 10 includes a first bottom surface 111, a second bottom surface 112, a first end surface 113, a second end surface 114, a first side surface 115, and a second side surface 116; wherein along the first direction, the first bottom surface 111 and the second bottom surface 112 are arranged opposite to each other and are used to install hinge components respectively. Along the second direction, the first end surface 113 and the second end surface 114 are arranged opposite to each other, wherein the second end surface 114 is a right-angle surface, and the second end surface 114 is configured as a splicing surface of the whiteboard; along the third direction, the first side surface 115 and the second side surface 116 are arranged opposite to each other.

[0057] The panel 12 is a rectangular plate, and the panel 12 covers the board body 11, and the two are combined to form a writable whiteboard. Specifically, the middle part of the panel 12 is bent at a right angle, and a right-angled surface with a certain width is formed in the middle part, and the width matches the thickness of the board body 11, that is, the right-angled surface is matched with the second end face 114. When the panel 12 covers the board body 11, the right-angled surface of the panel 12 is in contact with the second end face 114, and the other parts of the panel 12 cover the first side surface 115 and the second side surface 116 respectively.

[0058] like Figure 7 As shown, the panel 12 includes a first covering surface 121, a second covering surface 122 and a third covering surface 123, wherein along the third direction, the first covering surface 121 and the second covering surface 122 are arranged opposite to each other, and the first covering surface 121 and the second covering surface 122 are parallel to the plane formed by the first direction and the second direction, that is, the first covering surface 121 and the second covering surface 122 are parallel to the XY plane.

[0059] The third covering surface 123 is the middle part of the panel 12, and the third covering surface 123 is parallel to the plane formed by the first direction and the third direction, that is, the third covering surface 123 is parallel to the XZ plane. The third covering surface 123 is located at the edge of the first covering surface 121 and the second covering surface 122 along the second direction, and along the third direction, the third covering surface 123 is vertically connected to the first covering surface 121 and the second covering surface 122 respectively, and forms a right angle.

[0060] Furthermore, the space enclosed by the first covering surface 121, the second covering surface 122, and the third covering surface 123 is defined as a filling space 124, and the filling space 124 is used to accommodate the board body 11. When the panel 12 is covered on the board body 11, the board body 11 is located in the filling space 124, the first covering surface 121 and the second covering surface 122 cover the first side surface 115 and the second side surface 116 respectively, and the third covering surface 123 covers the second end surface 114 and fits with the second end surface 114.

[0061] In the embodiment of the present application, the overlapping area of ​​the panel 12 and the first side surface 115 and / or the second side surface 116 is configured as a writing surface, that is, the first covering surface and the second covering surface of the panel 12 are configured as writing surfaces.

[0062] Preferably, in the embodiment of the present application, both the first cover surface 121 and the second cover surface 122 are writing surfaces, that is, the whiteboard 10 can be written on both sides. In the two whiteboards 10, the second end surfaces 114 of both are splicing surfaces. When the writing whiteboard 100 is switched from the folded state to the unfolded state, the two whiteboards 10 rotate relative to each other, and the second end surfaces 114 of the two whiteboards 10 are close to each other and attached together.

[0063] See also Figure 1 and Figure 2 Among the two hinge assemblies 20, one hinge assembly 20 connects the first bottom surfaces 111 of the two whiteboards 10, and the other hinge assembly 20 connects the second bottom surfaces 112 of the two whiteboards 10, so that the two whiteboards 10 can be rotatably connected through the hinge assembly 20 to achieve relative flipping of the two whiteboards 10, so that the writing whiteboard 100 can switch between an unfolded state or a folded state.

[0064] like Figure 8 As shown, each hinge assembly 20 includes a first hinge 21 and a second hinge 22 which are symmetrically arranged. The first end of the first hinge 21 is connected to the first whiteboard 10, and the second end of the first hinge 21 extends to the joint. The first end of the second hinge 22 is connected to the second whiteboard 10, and the second end of the second hinge 22 is hinged to the second end of the first hinge 21 through a connecting pin 23 to form a hinge point.

[0065] Further, the second end of the first hinge 21 and the second end of the second hinge 22 both have connecting ears. The connecting ears are configured as arc-shaped ear pieces, and along the third direction, the connecting ears are provided with hinge holes and positioning holes at intervals, wherein when the writing whiteboard is in the unfolded state, the hinge holes are located outside the positioning holes, and further, the hinge holes are located outside the side of the writing whiteboard 100, and the first hinge 21 and the second hinge 22 are respectively inserted with connecting pins 23 in their hinge holes to form hinge points.

[0066] It is understandable that the writing whiteboard 100 provided in the embodiment of the present application further includes positioning pins 24, which are used to lock the writing whiteboard 100 in the unfolded state to prevent the writing whiteboard 100 from folding in the unfolded state, thereby facilitating writing by users.

[0067] For example, in the embodiment of the present application, when the writing whiteboard 100 is in the unfolded state, the positioning pins 24 can be installed in the positioning holes of the first hinge 21 and the second hinge 22 to achieve locking of the writing whiteboard 100. When the writing whiteboard 100 is in the folded state, there is no need to install the positioning pins 24 on the first hinge 21 and the second hinge 22. In other words, when the writing whiteboard 100 is in the folded state, the positioning pins 24 are in a loose position and the first hinge 21 and the second hinge 22 are not connected.

[0068] Preferably, the hinge point formed by the hinge assembly 20 is located outside the first side surface 115 or the second side surface 116, and the hinge points of the two hinge assemblies 20 are located on the same straight line, and the straight line is located outside the first side surface 115 or the second side surface 116 along the third direction. This arrangement allows the two whiteboards 10 to rotate toward one side, which is more convenient for the writing whiteboard 100 to be unfolded in the same plane than the whiteboard that can rotate toward both sides.

[0069] In the embodiment of the present application, when the writing whiteboard 100 is in the unfolded state, the straight line is centered along the second direction at the middle position of the writing whiteboard 100, that is, along the second direction, the hinge assembly 20 does not occupy the space at the joint of the two whiteboards 10, so that the unfolded writing whiteboard 100 has a good joint surface fit and no gap at the joint between the two, thereby forming a complete writing surface for easy writing.

[0070] Furthermore, when the writing whiteboard 100 is in the folded state, the two whiteboards 10 at least partially overlap. For example, the two whiteboards 10 are flipped in the opposite direction so that the whiteboards 10 at least partially overlap. Preferably, the two whiteboards of the writing whiteboard can be the same size, and the two whiteboards can be completely folded and attached together. In this way, the occupied area of ​​the writing whiteboard 100 can be reduced, so as to facilitate storage, packaging and transportation, thereby achieving the purpose of cost saving.

[0071] In the related art, the writing whiteboard cannot be folded or unfolded, and it occupies a large area, which is inconvenient to store and transport. The writing whiteboard 100 in the embodiment of the present application includes two foldable or unfoldable whiteboards 10. When in use, the writing whiteboard 100 is unfolded, and a seamless and flat writing surface is formed between the two whiteboards 10, which is convenient for writing and improves the user experience. In addition, when stored, the two whiteboards 10 can be folded, which reduces the occupied area and facilitates storage, packaging and transportation.

[0072] like Figures 9 to 11 As shown, the writing whiteboard 100 in the embodiment of the present application further includes a plurality of frames 30 , which are respectively engaged with the edges of the whiteboard 10 and cover the first bottom surface 111 , the second bottom surface 112 and at least a portion of the first end surface 113 .

[0073] For example, the frame 30 can be a metal frame. Along the first direction, the frame 30 is respectively arranged on both sides of the whiteboard 10 and covers the first bottom surface 111 and the second bottom surface 112. Along the second direction, the frame 30 is arranged on the side of the whiteboard 10 away from the splicing part, and the frame 30 covers the first end surface 113, and the second end surface 114 is not covered by the frame 30, that is, there is no frame 30 on the splicing surface.

[0074] When the frame 30 is installed on the edge of the whiteboard 10, the frame 30 at least covers a portion of the first side surface and the second side surface, so that the frame 30 presses the panel 12. In this way, the frame 30 is arranged on the edge of the whiteboard in the embodiment of the present application, which can protect the edge of the whiteboard 10, prevent the whiteboard 10 from being damaged due to collision, and reduce the probability of damage.

[0075] It is understandable that the second end face 114 of the whiteboard 10 in the embodiment of the present application is a splicing face, and the second end face 114 is not provided with a frame 30, that is, the frame 30 does not cover the second end face 114, so that the writing whiteboard has no frame 30 at its splicing. Such a setting can avoid the existence of a frame 30 at the splicing of two whiteboards 10, which leads to a larger splicing gap, so that when the writing whiteboard is in the unfolded state, a seamless and flat writing surface is formed between the two whiteboards 10 for easy writing.

[0076] The writing whiteboard 100 provided in the embodiment of the present application also includes a corner protector 40, and the corner protector 40 is arranged at the corner of each whiteboard 10, and the corner protector 40 is not only used to protect the corner of the whiteboard 10, but also can connect the two frames 30 extending in different directions of the corner together.

[0077] Furthermore, each corner protector 40 is a right-angled corner protector and is L-shaped as a whole, and the corner protector 40 is connected to the ends of the two frames 30 adjacent thereto. For example, each whiteboard 10 may be provided with two corner protectors 40, the two corner protectors 40 being a first corner protector and a second corner protector, wherein the first corner protector is provided at a corner formed between the first bottom surface 111 and the first end surface 113, and the first corner protector can connect the frames 30 provided on the first bottom surface 111 and the first end surface 113 together. The second corner protector is provided at a corner formed between the second bottom surface 112 and the first end surface 113, and the second corner protector can connect the frames 30 provided on the second bottom surface 112 and the first end surface 113 together.

[0078] In some embodiments, the entire cross-section of the frame 30 is U-shaped, and the frame 30 includes an end wall and two side walls, and the two side walls are located on both sides of the end wall and protrude from the end wall. When the frame 30 is installed to the edge of the whiteboard 10, the two side walls of the frame 30 are clamped on the first side surface 115 and the second side surface 116 of the board body 11, and the end wall is opposite to the end surface or bottom surface of the whiteboard 10.

[0079] The end of the frame 30 is connected to the corner protector 40, and the connection method includes but is not limited to a snap-fit ​​connection. In order to facilitate the snap-fitting of the frame 30 and the corner protector 40, the frame 30 is provided with a through hole, which is located on the end wall of the frame 30 and is arranged close to the edge of the frame 30. In this way, when the frame 30 and the corner protector 40 are snap-fitted, the frame 30 can have a certain amount of deformation, so that the corner protector 40 can be snap-fitted into the frame 30.

[0080] In order to improve the structural strength of the frame 30, in the embodiment of the present application, the end wall and the two side walls of the frame 30 are respectively provided with grooves, and the extension direction of the grooves is consistent with the extension direction of the frame 30. For example, the end wall and the two side wall parts of the frame 30 are recessed inward relative to the surrounding parts to form a groove. In this way, the groove structure can improve the impact resistance of the frame 30, thereby improving the protective effect of the frame 30.

[0081] Furthermore, the writing whiteboard 100 provided in the embodiment of the present application also includes two support blocks 50, which are arranged between the frame 30 and the edge of the board body 11. The support blocks 50 can support the frame 30, improve the impact resistance of the edge of the whiteboard 10, and prevent the edge of the whiteboard 10 from being damaged.

[0082] For example, each support block 50 corresponds to a frame 30 and is arranged in cooperation with the frame 30. When the frame 30 is installed at the edge of the whiteboard 10, a filling space is formed between the frame 30 and the edge of the whiteboard 10, and the support block 50 is embedded in the filling space, and one side of the support block 50 abuts against the end wall of the frame 30, and the other side abuts against the bottom surface or end surface of the board body 11. Preferably, part of the support block 50 abuts against the two side walls of the frame 30, so that the support effect of the support block 50 on the frame 30 can be improved.
