Description

Technical Field

[0001] This utility model relates to the field of whiteboard technology, specifically to a flip-up and foldable whiteboard. Background Technology

[0002] A whiteboard is a writing surface made of white writable material. Similar to a black and white board, it is a writing tool that can be repeatedly erased and rewritten, typically used for teaching, meetings, personal or family note-taking, etc. Whiteboards are usually rectangular. To maintain writing area while also being easy to carry, current technologies often make them into folding structures using hinges or similar mechanisms. For example, utility model patent CN222246655U discloses a whiteboard including two boards, with hinges on the top and bottom surfaces of the two boards, and the rotation center of the hinges being offset from the two boards.

[0003] While the hinge structure described above can achieve board folding, there is still a smaller gap between the two boards compared to the hinge structure, which affects the aesthetics. Such a hinge can only be placed on the back side of the writing surface, so when folding, the writing surface will face outwards. While this is convenient, it is also easy to scratch and damage the writing surface. If it is placed on the front side of the writing surface, part of the hinge will protrude from the writing surface, affecting writing. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a flip-foldable whiteboard that can be folded to allow for easy turning and turning.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A flip-up and foldable whiteboard includes a first whiteboard and a second whiteboard. Each of the two bottom surfaces of the first whiteboard is hinged to one end of a connecting piece. The other end of the connecting piece is provided with a groove or a slider. The second whiteboard is correspondingly provided with a slider or a groove. While the groove and the slider are slidably connected, the slider can also rotate within the groove. The second whiteboard and the first whiteboard can rotate relative to each other at both ends of the connecting piece, and the second whiteboard can slide along the groove.

[0007] Furthermore, the second whiteboard has the groove, and the connecting piece is rotatably connected to the slider.

[0008] Furthermore, a first fixing rod is provided at the hinge point between the connecting piece and the first whiteboard, passing through the first whiteboard. The first fixing rod connects the two connecting pieces into one unit. A second fixing rod is provided at the hinge point between the connecting piece and the second whiteboard, connecting the two sliders into one unit.

[0009] Furthermore, the mating surfaces of the first whiteboard and the second whiteboard are respectively provided with first magnet groups that attract each other.

[0010] Furthermore, the middle portions of the first whiteboard and the second whiteboard are respectively embedded with mutually attractive second magnet groups, and the side of the second whiteboard near the connecting piece is also provided with a third magnet group with the opposite polarity to the second magnet group of the second whiteboard.

[0011] Furthermore, the back of the first whiteboard and / or the second whiteboard is also hinged with a U-shaped bracket, and the first whiteboard and / or the second whiteboard are provided with an angle adjustment component adapted to the U-shaped bracket.

[0012] Furthermore, the angle adjustment component includes: a locking bolt is provided on the contact surface between the U-shaped bracket and the first whiteboard and / or the second whiteboard, and the locking bolt is provided with a rotating handle.

[0013] Furthermore, the height of the U-shaped bracket is greater than half of the first whiteboard or the second whiteboard. When the U-shaped bracket rotates at a certain angle, the angle adjustment component locks in, forming a bracket. When the U-shaped bracket rotates 180°, the U-shaped bracket will extend beyond the edge of the first whiteboard and / or the second whiteboard to form a handle.

[0014] Preferably, the back of the writing back panel is provided with a buckle adapted to the handle.

[0015] Furthermore, the second whiteboard is also connected to the third whiteboard via the connecting piece, the groove, and the slider.

[0016] Furthermore, an outer frame is provided at the outer edge of the first and second whiteboards, and the outer frame is provided with an opening to avoid interference with the rotation of the connecting piece.

[0017] The advantages and beneficial effects of this utility model are as follows:

[0018] 1. Through the cooperation of the slide and the slider, and the hinged design of the connecting piece between the first and second whiteboards, the two whiteboards can rotate relative to each other or slide along the slide. When only the first whiteboard is needed, the second whiteboard can be rotated to the back of the first whiteboard. At this time, the rotation between the connecting piece and the slider can be used to make the writing surface of the second whiteboard fit against the back of the first whiteboard. When folded, the writing surfaces of the two whiteboards can fit against each other to protect the writing surfaces from contamination and wear.

[0019] 2. The second whiteboard has a groove, and the connecting piece rotates to connect the slider. This avoids the need for the connecting piece to have a groove, which would require the second whiteboard to have a slider, thus improving the aesthetics of the structure. The first and second fixing rods pass through the corresponding whiteboards to connect the connecting piece and the slider as one unit, enhancing the stability of the structure.

[0020] 3. By setting a first group of mutually attractive magnets on the mating surface of the whiteboard and a second group of magnets on the side away from the connecting piece, the whiteboard can be quickly fixed in both unfolded and folded states, improving the convenience and efficiency of use.

[0021] 4. The design of the U-shaped bracket and its angle adjustment components (such as locking bolts and rotating handles) provide additional support and angle adjustment functions for the whiteboard, enabling it to be supported three-dimensionally as a display board and increasing the applicable scenarios of the product.

[0022] 5. Modular expansion capability: The second whiteboard can be connected to a third whiteboard, or even more, through a similar connection mechanism. This modular design allows the product to be easily expanded as needed to meet the usage requirements of different scales and occasions. Attached Figure Description

Detailed Implementation

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0030] Example 1

[0031] Please see Figures 1-5A flip-up and foldable whiteboard includes a first whiteboard 10 and a second whiteboard 20. Each of the two bottom surfaces of the first whiteboard 10 is hinged to one end of a connecting piece 11, and the other end of the connecting piece 11 is provided with a slider 12. The second whiteboard 20 is correspondingly provided with a sliding groove 13. The slider 12 is disc-shaped so that it can also rotate within the sliding groove 13. The second whiteboard 20 and the first whiteboard 10 can rotate relative to each other at both ends of the connecting piece 11, and the second whiteboard 20 can slide along the sliding groove 13. A first fixing rod 14 is provided through the hinge point between the connecting piece 11 and the first whiteboard 10, passing through the first whiteboard 10. The first fixing rod 14 connects the two connecting pieces 11 into one unit, and a second fixing rod 21 passes through the second whiteboard 20, connecting the two sliders 12 into one unit.

[0032] The first whiteboard 10 and the second whiteboard 20 are respectively provided with mutually attractive first magnet groups 15 on their mating surfaces for fixing the two whiteboards together when they are unfolded. The first whiteboard 10 and the second whiteboard 20 are respectively provided with mutually attractive second magnet groups 16 on the side away from the connecting piece 11. The second whiteboard 20 is also provided with a third magnet group 17 on the side closer to the connecting piece 11, with the polarity opposite to that of the second magnet group 16. Both the second magnet group 16 and the third magnet group 17 are used to fix the two whiteboards together when they are folded. The difference is that the second magnet group 16 is used for the writing surface of the second whiteboard 20 to adhere to the first whiteboard 10, while the third magnet group 17 is used for the two back sides to adhere to each other.

[0033] A U-shaped bracket 30 is hinged to the back of the first whiteboard 10 and the second whiteboard 20. An angle adjustment assembly is provided for the first whiteboard 10 and the second whiteboard 20. The angle adjustment assembly includes: a locking bolt 31 on the contact surface between the U-shaped bracket 30 and the first whiteboard 10 and the second whiteboard 20; and a rotating handle 32 on the locking bolt 31. The height of the U-shaped bracket 30 is greater than half the height of the whiteboard. When the U-shaped bracket rotates 0-170°, rotating the rotating handle tightens the locking bolt to lock the angle, forming the bracket. When the U-shaped bracket rotates 180°, it extends beyond the edge of the first whiteboard and / or the second whiteboard to form a handle. A buckle 33 adapted to the handle is also provided on the back of the writing whiteboard. An outer frame 40 is provided at the outer edge of the first whiteboard 10 and the second whiteboard 20, and the outer frame has an opening 41 to avoid interference with the rotation of the connecting piece.

[0034] Example 2

[0035] Please see Figure 4 The difference from Embodiment 1 is that the second whiteboard 20 is also connected to the third whiteboard via a connecting piece 11, a groove 13 and a slider 12.

[0036] Working principle:

[0037] The whiteboard consists of a first whiteboard 10 and a second whiteboard 20, which are hinged together by connecting pieces 11. One end of each connecting piece 11 is hinged to the bottom surface of the first whiteboard 10, and the other end is provided with a slider 12. These sliders 12 are designed in a disc shape to rotate in corresponding grooves 13 on the second whiteboard 20. This design allows the second whiteboard 20 to rotate and slide relative to the first whiteboard 10. To ensure the stability of the two whiteboards in the unfolded state, first magnet groups 15 that attract each other are respectively provided on the mating surfaces of the first whiteboard 10 and the second whiteboard 20. When the two whiteboards are unfolded, these magnet groups can fix each other, keeping the whiteboards flat and stable.

[0038] Rotating the two whiteboards along the connecting piece at two points allows the writing whiteboards to fold into a folded state. In the folded state, the first whiteboard 10 and the second whiteboard 20 have mutually attracting second magnet groups 16 embedded on the side away from the connecting piece 11, while the second whiteboard 20 has a third magnet group 17 with opposite polarity to the second magnet group 16 on the side closer to the connecting piece 11. The design of these magnet groups allows the writing surface or back side of the second whiteboard 20 to fit against the first whiteboard 10 in the folded state.

[0039] To further enhance the functionality of the whiteboard, a U-shaped bracket 30 is hinged to the back of the first whiteboard 10 and the second whiteboard 20. This bracket can be adjusted at its angle to the whiteboard using an angle adjustment assembly. The angle adjustment assembly includes a locking bolt 31 and a rotating handle 32. When the U-shaped bracket 30 rotates to a certain angle, the angle can be locked by rotating the rotating handle and tightening the locking bolt, forming a stable bracket. When the U-shaped bracket 30 rotates to 180°, it extends beyond the edge of the first and / or second whiteboard, forming a handle for easy carrying of the whiteboard in its folded state. Finally, to protect the edges of the whiteboard and prevent interference with the connecting piece 11 during rotation, an outer frame 40 is provided at the outer edge of the first whiteboard 10 and the second whiteboard 20. The outer frame has an opening 41 to avoid interfering with the rotation of the connecting piece.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
