Detailed implementation manners

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , Embodiment 1, a jigsaw puzzle board with a multifunctional bracket, including a jigsaw puzzle board body 10, wherein a rotatable bracket assembly 70 is arranged on the jigsaw puzzle board body 10, and the bracket assembly 70 includes a first movable bracket 71 and a second movable bracket 72 that can rotate independently or relatively. The first movable bracket 71 is used to support the jigsaw puzzle board body 10 so that the jigsaw puzzle board body 10 is in an inclined support state relative to the placement plane, and the second movable bracket 72 is used to form an article placement position 80, or cooperate with the jigsaw puzzle board body 10 to form an article placement position 80.

[0030] When using traditional jigsaw puzzle products, users usually place the jigsaw puzzle board body 10 on a horizontal table, which requires them to lower their heads for a long time, easily causing neck fatigue, and the light reflection in the horizontal state will interfere with the observation of the details of the jigsaw puzzle. To solve this problem, the jigsaw puzzle board with a multifunctional bracket is designed with a rotatable first movable bracket 71. The first movable bracket 71 and the jigsaw puzzle board body 10 can be connected by a common shaft connection method. The shaft serves as a fulcrum. According to the lever principle, when the first movable bracket 71 rotates, one end rotates around the fulcrum, and the other end lifts upward, applying an upward supporting force to the jigsaw puzzle board body 10, thereby changing the included angle between the jigsaw puzzle board body 10 and the placement plane. In a possible implementation manner, a plurality of preset card slots can be arranged on the first movable bracket 71 to cooperate with the corresponding card blocks on the jigsaw puzzle board body 10 to achieve fixation at different inclination angles; or a rotating shaft with damping can be used. The user manually adjusts it, and relying on the damping characteristics of the rotating shaft, the jigsaw puzzle board body 10 is stabilized at the desired inclination angle. By adjusting the rotation angle of the first movable bracket 71, the jigsaw puzzle board body 10 can reach different inclination degrees, meeting the diverse needs of users for the observation angle, effectively improving the light reflection situation, and reducing visual interference. Considering that people often need to refer to external materials during the jigsaw puzzle process, such as pictures and video tutorials in mobile phones and tablets, but existing jigsaw puzzle products lack the corresponding convenient placement function. To address this issue, the puzzle board with a multi-functional bracket is provided with a second movable bracket 72 that can rotate independently or relatively. The second movable bracket 72 and the puzzle board body 10 can be flexibly rotated through common shaft connection methods. When a reference device needs to be placed, rotate the second movable bracket 72. At the end of the second movable bracket 72, a feasible design is to set a clamping groove made of elastic rubber material. If it fits the edge of the puzzle board body 10, the edge of the puzzle board body 10 can be clamped through the clamping groove. If the corresponding part of the puzzle board body 10 is made of metal, a magnetic patch can also be used to nest with the corresponding part of the puzzle board body 10 by magnetic attraction, so that the two are combined to form an item placement position 80. This way of using rotatable components to combine and construct a new functional structure in different positions provides a dedicated area for users to place devices. In summary, the first movable bracket 71 makes the puzzle board body 10 in an inclined support state. Users do not need to continuously lower their heads excessively, and the pressure on the neck muscles is reduced, alleviating neck fatigue to a certain extent. At the same time, the inclined puzzle board body 10 changes the reflection path of light, so that the light is no longer concentrated and reflected into the user's eyes, reducing the impact of glare on the observation of puzzle details. Users can more clearly distinguish the patterns, colors, and splicing gaps of the puzzles on the puzzle board body 10, thereby improving the operation efficiency of the puzzle. The item placement position 80 formed or cooperated by the second movable bracket 72 provides a stable placement space for devices such as mobile phones and tablets. Compared with placing them randomly beside the puzzle board body 10, placing the devices in a dedicated placement position reduces the possibility of slipping and damage due to collision. Moreover, concentrating the devices in the placement position near the puzzle board body 10 saves desktop space, and users can conveniently and quickly view materials during the puzzle process, enhancing the convenience of the puzzle experience.

[0031] In Embodiment 1 of the present invention, the bracket assembly 70 further includes a connecting member 73 connected to the puzzle board body 10. The first movable bracket 71 and the second movable bracket 72 are respectively movably connected to the connecting member 73 and can rotate around the connection point. Among them, a connecting shaft 74 is provided on the connecting member 73. The first movable bracket 71 is sleeved on the connecting shaft 74 and is rotationally connected to the connecting shaft 74. The second movable bracket 72 is sleeved on the connecting shaft 74 and is located between the first movable bracket 71 and the connecting member 73, and is rotationally connected to the connecting shaft 74. The first movable bracket 71 and the second movable bracket 72 can respectively rotate relative to the connecting member 73 around the connecting shaft 74, and the first movable bracket 71 and the second movable bracket 72 can also rotate relative to each other around the connecting shaft 74.

[0032] The connecting member 73 is provided to connect the puzzle board body 10. The first movable bracket 71 and the second movable bracket 72 are respectively movably connected to the connecting member 73 and are rotated by a connecting shaft 74 sleeved on the connecting member 73. This design utilizes the stability of shaft connection. As the core rotating component, the connecting shaft 74 closely cooperates with the first movable bracket 71 and the second movable bracket 72. Since the first movable bracket 71 is sleeved on the connecting shaft 74 and rotatably connected to the connecting shaft 74, and the second movable bracket 72 is also sleeved on the connecting shaft 74 and is between the first movable bracket 71 and the connecting member 73, in this nested structure, when the first movable bracket 71 and the second movable bracket 72 are stressed, the connecting shaft 74 can evenly disperse the force to the connecting member 73 and then transmit it to the puzzle board body 10, ensuring the stability of the connection and avoiding loosening or damage of components due to uneven stress during use. The first movable bracket 71 and the second movable bracket 72 can respectively rotate relative to the connecting member 73 around the connecting shaft 74, and they can also rotate relative to each other around the connecting shaft 74. By setting the relative positions and rotational freedoms of different movable brackets on the same connecting shaft 74, the bracket assembly 70 is given a variety of combined rotation modes. For example, when it is necessary to adjust the tilt angle of the puzzle board body 10, the first movable bracket 71 can rotate alone around the connecting shaft 74, and when adjusting the item placement position 80, the second movable bracket 72 can rotate relative to the connecting member 73 or the first movable bracket 71, or they can rotate in cooperation to meet the diverse requirements for the functions of the puzzle board in different scenarios. That is, the separate or combined rotation modes of the first movable bracket 71 and the second movable bracket 72 greatly enrich the function adjustment dimension of the puzzle board.

[0033] In Embodiment 1 of the present invention, a slot 81 corresponding to the connecting member 73 is provided at the top of the puzzle board body 10, and the bracket assembly 70 is connected to the puzzle board body 10 by inserting the connecting member 73 into the slot 81. Among them, the connecting member 73 is of an insertion plate structure.

[0034] Setting a slot 81 corresponding to the connecting member 73 at the top of the puzzle board body 10 and inserting the connecting member 73 of the insertion plate structure into the slot 81 to realize the connection between the bracket assembly 70 and the puzzle board body 10 is a modular connection design concept. The shapes and sizes of the slot 81 and the insertion plate match, and a stable connection structure is formed by the tight fit after the insertion plate is inserted into the slot 81. This design takes the bracket assembly 70 as an independent module, and through a simple plugging and unplugging action, the assembly or disassembly with the puzzle board body 10 can be realized, which is convenient for the component assembly in the production process and is also beneficial for the subsequent separate maintenance or replacement of the bracket assembly 70. The position of the slot 81 is set at the top of the puzzle board body 10, providing a clear insertion position and direction guidance for the plug board. When the plug board structure is inserted into the slot 81, the edge of the slot 81 plays a guiding role to ensure that the plug board can be inserted accurately. And after being inserted in place, the cooperation between the slot 81 and the plug board can position the bracket assembly 70, so that the first movable bracket 71 and the second movable bracket 72 are in the correct positions in the initial state, facilitating subsequent operations such as angle adjustment and ensuring the normal functioning of the overall function of the puzzle board.

[0035] In Embodiment 1 of the present invention, after the connecting member 73 is inserted into the slot 81 of the puzzle board body 10, the first movable bracket 71 and the second movable bracket 72 are fixed to the top of the puzzle board body 10; Wherein, the first movable bracket 71 can support the puzzle board body 10 after rotation, and the second movable bracket 72 forms an article placement position 80 in cooperation with the top of the puzzle board body 10 after rotation.

[0036] After the connecting member 73 is inserted into the slot 81 of the puzzle board body 10, the first movable bracket 71 and the second movable bracket 72 are fixed to the top of the puzzle board body 10. This design constructs an integrated structural system. The fixation of the connecting member 73 in the slot 81 ensures a stable connection relationship between the first movable bracket 71 and the second movable bracket 72 and the top of the puzzle board body 10, making them a whole. The first movable bracket 71 can support the puzzle board body 10 after rotation, and the second movable bracket 72 forms an article placement position 80 in cooperation with the top of the puzzle board body 10 after rotation. This is based on the design idea of functional coordination. Under the fixation of the same connecting member 73, the first movable bracket 71 and the second movable bracket 72 each undertake different functions. The first movable bracket 71 changes the placement angle of the puzzle board body 10 by rotation. Using the lever principle, with the connection point with the connecting member 73 as the fulcrum, the inclination degree of the puzzle board body 10 is adjusted. The second movable bracket 72 uses rotation to cooperate with the top of the puzzle board body 10 at a specific position, such as by complementary shapes, position fitting, etc., to construct a space suitable for placing articles (such as a mobile phone holder), meeting different needs of users during the puzzle process. Specifically, for example, the second movable bracket 72 rotates upward to form an article placement position 80 that can support devices such as mobile phones with the edge or corresponding groove position at the top of the puzzle board body 10.

[0037] In Embodiment 1 of the present invention, the puzzle board body 10 can be folded in half, and the slot 81 corresponds to the folding position of the puzzle board body 10.

[0038] Specifically, for example, the puzzle board body 10 is provided with a hinge structure (hinge) along its central axis so that the puzzle board body 10 can be folded in half.

[0039] The puzzle board body 10 can be folded in half, and the slot 81 corresponds to the folded position of the puzzle board body 10. This design fully considers the convenience of disassembling the bracket assembly 70 before folding. The slot 81 is set at the folded position. When the puzzle board body 10 needs to be folded, the user can easily pull out the connecting piece 73 of the plug-in structure from the slot 81, and then remove the bracket assembly 70. This design utilizes the ease of plugging and unplugging the slot 81 and the connecting piece 73, so that the disassembly operation does not require the help of complex tools, reduces the difficulty of user operation, ensures that the folding process proceeds smoothly, and avoids the obstruction of the folding action by the bracket assembly 70; The slot 81 is set in the folding position. When the puzzle board body 10 is in the unfolded state, the position can be fully utilized to install the bracket assembly 70, thereby realizing efficient use of space. From the perspective of spatial layout, the folding position is relatively flat when unfolded, providing a suitable foundation for the installation of the bracket assembly 70. When folding is required, after the bracket assembly 70 is removed, the folding position can fit naturally, and there will be no large gaps or unevenness after folding due to the slot 81 or other structures, thereby ensuring the compactness of the puzzle board body 10 after folding and effectively saving storage space.

[0040] In Embodiment 1 of the present invention, after the connecting member 73 is connected to the puzzle board body 10 , when the puzzle board body 10 is in the unfolded state, constraints are imposed on the puzzle board body 10 to suppress its rotational freedom around the folding axis to maintain the unfolding stability of the puzzle board body 10 .

[0041] After the connecting piece 73 is connected to the puzzle board body 10, when the puzzle board body 10 is in the unfolded state, a constraint is imposed on it to inhibit the rotational freedom around the folding axis; after the connecting piece 73 is inserted into the slot 81 corresponding to the folding position, through its own shape, size and close fit with the slot 81, a resistance is formed in the direction in which the puzzle board body 10 may rotate around the folding axis. For example, the connecting piece 73 of the plug-in structure is in the slot 81, and its side surface is closely fitted with the inner wall of the slot 81. When there is an external force that causes the puzzle board body 10 to rotate around the folding axis, the friction between the connecting piece 73 and the slot 81 and the structural resistance of the two cooperate with each other, jointly prevent the rotation of the puzzle board body 10, thereby maintaining its unfolding stability; From a structural perspective, when the jigsaw board body 10 is unfolded for use, especially when the support assembly 70 plays a supporting role or constructs the article placement position 80, there may be a tendency to rotate in the folding direction due to uneven force. At this time, the connecting member 73 plays a role in stabilizing the structure. Its connection with the jigsaw board body 10 is like adding a solid defense line at the folding axis. By restricting the rotation of the jigsaw board body 10 around the folding axis, the rigidity of the entire jigsaw board structure in the unfolded state is ensured, avoiding deformation of the jigsaw board or malfunction due to accidental rotation. Thus, the jigsaw board body 10 can always maintain a stable working plane, preventing the jigsaw pieces from shifting due to the shaking or rotation of the jigsaw board during the jigsaw process, and also avoiding the slipping of the placed articles, enhancing the safety and reliability of the user experience.

[0042] In Embodiment 1 of the present invention, a storage groove 82 is further provided at the top of the jigsaw board body 10. The storage groove 82 is used to store the first movable support 71 and the second movable support 72. Among them, the slot 81 is located in the storage groove 82.

[0043] The provision of the storage groove 82 at the top of the jigsaw board body 10 for storing the first movable support 71 and the second movable support 72, and the slot 81 being located in the storage groove 82 is based on the design concept of space integration and utilization; the storage groove 82 makes full use of the idle space at the top of the jigsaw board body 10 to centrally store the originally scattered support assembly 70 and the connecting member 73. When the jigsaw board is not in use, or only one of the first movable support 71 and the second movable support 72 is used, or neither of them is used, the user can orderly put the corresponding idle parts into the storage groove 82; for example, if only the first movable support 71 is used to support the jigsaw board, the second movable support 72 can be stored in the storage groove 82; at the same time, setting the slot 81 in the storage groove 82 realizes the integration of the storage and connection functional areas, and the operation space is concentrated when installing and disassembling the support assembly 70, which is convenient for the user to operate.

[0044] Please refer to Figure 7 , in an embodiment of the present invention, a first connection position 83 and a second connection position 84 are provided on the jigsaw board body 10. The first movable support 71 is movably connected to the first connection position 83, and the second movable support 72 is movably connected to the second connection position.

[0045] Different from the way that the first movable bracket 71 and the second movable bracket 72 are jointly connected to the same connecting piece 73, in this design, a first connecting position 83 and a second connecting position 84 are provided on the puzzle board body 10 to realize their separate installation; the second movable bracket 72 is still arranged at the top of the puzzle board body 10 and can be movably connected to the puzzle board body 10 by a common shaft connection method. After rotation, it cooperates with the puzzle board body 10 to form an article placement position 80. The first movable bracket 71 is arranged at the middle position (or other suitable positions) on the back of the puzzle board body 10 and adopts a shaft connection method to enable the first movable bracket 71 to rotate around the shaft and support the puzzle board body 10; due to the characteristics of the connection positions and structural designs of the components under this connection method, the puzzle board body 10 cannot be folded in half, but it has unique advantages in terms of bracket installation, function realization, and structural stability. For example, the independent installation of each bracket reduces mutual interference, and the connection design at specific positions is more suitable for the exertion of its functions, etc.

[0046] Please refer to Figures 8-12 , Embodiment 2, a puzzle board with a magnetic frame, comprising a puzzle board body 10 and a frame 30 detachably connected to the puzzle board body 10. A working layer 40 for assisting in puzzle assembly is provided on the surface of the puzzle board body 10, and the frame 30 is used to press the working layer 40 to achieve its fixation.

[0047] In the technical solution of this Embodiment 2, the working layer 40 is arranged on the surface of the puzzle board body 10 and is a key part that directly contacts the puzzle pieces and assists in the puzzle operation; from the perspective of the material, common materials for the working layer 40 such as felt have unique surface characteristics. The fiber structure on the surface of the felt can provide a certain frictional force for the puzzle pieces, enabling the pieces to stay relatively stably on the surface of the working layer 40 during the splicing process and not easily slide randomly, which is crucial for the smooth progress of the puzzle; furthermore, the working layer 40, the puzzle board body 10, and the frame 30 form an organic overall structure. It is placed on the surface of the puzzle board body 10, and the frame 30 surrounds the edge of the working layer 40 and presses and fixes it. This structural design ensures that the working layer 40 always maintains a stable position during the puzzle process and will not be displaced or wrinkled due to factors such as vibration and collision during the operation, thereby providing a stable basis for the puzzle operation; By adopting a frame 30 that is detachably connected to the puzzle board body 10, a flexible structural system is constructed. This design allows users to conveniently separate the frame 30 from the puzzle board body 10 when needed, and then can easily reach and operate the working layer 40 on the surface of the puzzle board body 10. The principle lies in using the detachable connection method to break the fixed mode of the integration of the traditional puzzle board frame 30 and the working layer 40, creating conditions for operations such as replacing the working layer 40. The function of the frame 30 is not only for decoration or simple enclosure, but more importantly, it is used to press the working layer 40. When the frame 30 is connected to the puzzle board body 10, through appropriate pressure application methods (such as the weight of the frame 30 itself, the pressure generated by the connection structure, the acting force, etc.), it ensures that the working layer 40 firmly adheres to the surface of the puzzle board body 10, preventing the working layer 40 from shifting, wrinkling, etc. during use, which may affect the puzzle operation, and ensuring the stability of the working layer 40 during the puzzle process.

[0048] In summary, Embodiment 2 of the present invention can effectively: Solve the problem of non-replaceable working layer 40: Aiming at the pain point that the felt of the traditional felt puzzle board cannot be replaced due to glue adhesion, the detachable frame 30 of this design enables users to easily remove the frame 30 when the felt is adhered to the puzzle or the felt has other unusable conditions, remove the old working layer 40 and replace it with a new one. This design effectively avoids the situation of having to discard the entire puzzle board due to damage or adhesion of the working layer 40 to the puzzle, greatly saving resources and reducing the user's usage cost; Improve the problem of decreasing friction: As the usage time increases, the friction of the working layer 40 will gradually decrease. In this design, when the friction of the working layer 40 (such as felt) decreases and affects the puzzle operation, the user can replace the new working layer 40 by removing the frame 30. The new working layer 40 has good initial friction, which can provide stable support for the puzzle pieces, significantly improving the stability and operation experience of the puzzle. Especially for complex puzzles with a large number of pieces, it ensures that the pieces are not easy to slide or shift during the splicing process; Cope with the problem of difficult cleaning: Since the felt material is easy to adsorb dust and hair and is difficult to clean, this design enables users to regularly remove the working layer 40 alone for cleaning or directly replace it with a new one through the detachable frame 30. This not only keeps the puzzle board beautiful, but also always maintains good friction between the puzzle pieces and the surface of the working layer 40, ensuring the smooth progress of the puzzle operation and improving the overall usage effect of the puzzle board.

[0049] In Embodiment 2 of the present invention, the frame 30 and the puzzle board body 10 are magnetically coupled; A magnetic connection component is provided between the puzzle board body 10 and the frame 30, and stable magnetic coupling between the frame 30 and the puzzle board body 10 is achieved through the magnetic connection component; The magnetic connection assembly includes a permanent magnet component arranged at the edge of the puzzle board body 10, and a magnetic matching component arranged at a corresponding position of the frame 30; The permanent magnet component is a permanent magnet block or distributed permanent magnet particles, and the magnetic matching component is a metal sheet or a magnetic rubber sheet that can be attracted by the permanent magnet, or another magnetic component with a magnetic pole opposite to that of the permanent magnet component.

[0050] By utilizing the attraction of opposite poles of magnetic materials, magnetic connection components are respectively arranged at the corresponding positions of the frame 30 and the puzzle board body 10, such as embedding a permanent magnet at the edge of the puzzle board body 10, and installing an attractable metal patch or a magnet with opposite magnetic poles at the corresponding position of the frame 30. This design constructs a connection method that does not require a complex mechanical structure. The user only needs to bring the frame 30 close to the puzzle board body 10, and the magnetic force can automatically guide and realize the quick connection between the two, which greatly simplifies the installation process of the frame 30 and improves the convenience of user operation. Furthermore, the magnetic attraction can, to a certain extent, adapt to the slight size deviations or position errors generated by the puzzle board body 10 and the frame 30 during the manufacturing and installation process. Since the range of magnetic action has a certain elasticity, when the positions of the two deviate slightly, the magnetic force will automatically adjust the position of the frame 30 to make it fit the puzzle board body 10 precisely, ensuring that the working layer 40 is evenly compressed and maintains a good working state.

[0051] Preferably, the detachable connection between the puzzle board body 10 and the frame 30 can also be a snap, screw or other connection method, which is not limited here; the present invention preferably adopts a magnetic attraction matching method, so that during use, the user can quickly complete the loading and unloading operations of the frame 30 with bare hands without the aid of additional tools. For users who frequently change the working layer 40, this feature greatly saves operation time and significantly improves the use efficiency.

[0052] In Embodiment 2 of the present invention, the working layer 40 is a felt layer, and the felt layer covers the surface of the area of ​​the jigsaw puzzle body 10 used for splicing puzzle pieces.

[0053] As mentioned above, the working layer 40 is a felt layer, which has a unique fiber structure. These fibers are interwoven to form an irregular surface. When the puzzle pieces are placed on the surface of the felt layer, a large friction force will be generated between the pieces and the felt fibers. The felt layer is covered on the surface of the area of ​​the puzzle board body 10 for splicing puzzle pieces, which utilizes this friction characteristic to provide a stable placement basis for the puzzle pieces. The area of the jigsaw board body 10 for piecing together the jigsaw puzzles is the core part for jigsaw operations. Precisely covering the felt layer on this area can closely fit the surface contour of the jigsaw board body 10, make full use of the space of this area, and provide a complete and adaptable working plane for the jigsaw puzzles. At the same time, due to the certain flexibility of the felt material, it can better adapt to the possible slight unevenness on the surface of the jigsaw board body 10, further ensuring good contact with the jigsaw puzzle pieces, enhancing the friction effect, and ensuring the smoothness of the jigsaw process.

[0054] In Embodiment 2 of the present invention, the jigsaw board body 10 is provided with a hinge structure along its central axis, so that the jigsaw board body 10 can be folded in half. The border 30 is correspondingly divided into a first half-border 301 and a second half-border 302 along the central axis of the jigsaw board body 10.

[0055] The hinge structure (such as a hinge) is provided along the central axis of the jigsaw board body 10 to achieve the folding in half of the jigsaw board body 10. This design draws on the principle of common folding furniture, and realizes the rotational folding of components through the hinge points. When the jigsaw board is not in use or needs to be stored, the user can fold the jigsaw board body 10 in half along the hinge structure, effectively reducing its occupied area in space. For users with limited home space or who need to frequently move the jigsaw board, this design can flexibly adjust the spatial form of the jigsaw board to meet the spatial requirements in different scenarios. To cooperate with the folding function of the jigsaw board body 10, the border 30 is correspondingly divided into a first half-border 301 and a second half-border 302 along the central axis of the jigsaw board body 10. Such a design ensures that when the jigsaw board body 10 is folded, the border 30 can also be adapted accordingly. When the jigsaw board body 10 is folded in half, the first half-border 301 and the second half-border 302 can approach and dock with each other, continuing to play the role of pressing and fixing the working layer 40 by the border 30, while maintaining the integrity of the overall structure. The design principle is to make the folding action of the border 30 synchronous and coordinated with that of the jigsaw board body 10, and maintain the functional consistency of the product in different states.

[0056] Preferably, at the docking joint of both the first half frame 301 and the second half frame 302, a corresponding connection mechanism can be designed. For example, mutually matching magnetic attraction strips can be respectively arranged on the opposite edges of the first half frame 301 and the second half frame 302. Using the principle of magnetic attraction, when the puzzle board body 10 is folded in half, the magnetic attraction strips are automatically attracted, tightly connecting the two half frames 30. The operation is simple and the connection is stable. It can also be designed as a snap - type docking structure. A convex snap is arranged on the first half frame 301, and a groove and card slot are arranged at the corresponding position of the second half frame 302. When folding, the convex snap is accurately inserted into the groove and card slot to achieve a reliable connection and prevent the two half frames 30 from accidentally separating during movement or use. A design method with a gap can also be adopted. When the puzzle board body 10 is folded, the first half frame 301 and the second half frame 302 approach each other but do not completely fit, and a gap with a certain width is reserved in the middle. This design is mainly based on the considerations of the thermal expansion and contraction of materials and manufacturing tolerances. At different ambient temperatures, the puzzle board material may undergo thermal expansion and contraction. The gap can provide space for the expansion and contraction of the frame 30 material, preventing the deformation or damage of the docking joint of the frame 30 due to thermal expansion. At the same time, during the manufacturing process, due to process limitations, there may be slight deviations in the dimensions of the half frame 30. The existence of the gap can effectively accommodate these tolerances, enabling the two half frames 30 to be relatively smoothly docked in the folded state, maintaining the stability of the product structure. And when folding, the gap will not affect the pressing and fixing effect of the frame 30 on the working layer 40, maintaining the integrity of the overall structure, enabling the folding actions of the frame 30 and the puzzle board body 10 to be synchronized and coordinated, and maintaining the functional consistency of the product in different states.

[0057] In Embodiment 2 of the present invention, a boss structure 50 is provided on the surface of the puzzle board body 10. The upper surface of the boss structure 50 constitutes the placement plane of the working layer 40, and a step groove 501 adapted to the frame 30 is arranged around the periphery of the boss. The frame 30 can be embedded in the step groove 501.

[0058] A boss structure 50 is provided on the surface of the puzzle board body 10, and its upper surface serves as the placement area for the working layer 40. The boss separates the working layer 40 from other parts of the puzzle board body 10, reducing the influence of structural changes in other parts of the body on the flatness of the working layer 40, providing stable support for the working layer 40, and ensuring that the working layer 40 always remains flat. A step groove 501 is provided around the boss. The step groove 501 is adapted in size and shape to the frame 30. When installing the frame 30, the frame 30 is inserted (which can also be regarded as snapped in or placed) into the step groove 501. The step groove 501 positions the frame 30. For a puzzle board using magnetic attraction connection, the frame 30 is first positioned through the step groove 501, and then the magnetic attraction connection component is used to connect the puzzle board body 10 and the frame 30. The step groove 501 ensures that the frame 30 is accurately in place during installation, enabling the magnetic poles of the magnetic attraction component to be correctly aligned, thereby enhancing the stability of the magnetic attraction connection and further ensuring the pressing effect of the frame 30 on the working layer 40.

[0059] In Embodiment 2 of the present invention, the frame 30 has a pressing part 303 and a connecting part 304 that are an integral structure. The pressing part 303 corresponds to the placement plane of the boss structure 50 on the surface of the puzzle board body 10 and is used to press the working layer 40 provided on the placement plane. The connecting part 304 corresponds to the step groove 501 around the circumferential side of the boss structure 50 and is used to be inserted into the step groove 501 to achieve a firm connection between the frame 30 and the puzzle board body 10.

[0060] The pressing part 303 corresponds to the placement plane of the boss structure 50 on the surface of the puzzle board body 10. Its design purpose is to provide a uniform and stable pressing force for the working layer 40. When the frame 30 is installed on the puzzle board body 10, the pressing part 303 directly acts on the edge position of the working layer 40, and uses its own gravity and the elastic deformation pressure generated after installation to tightly press the working layer 40 on the placement plane of the boss structure 50. The connecting part 304 is adapted to the step groove 501 around the circumferential side of the boss structure 50. During installation, it can be embedded therein to achieve preliminary positioning. Preferably, the magnetic attraction connecting component can be arranged on the connecting part 304. For example, small magnets or magnetic materials are distributed on the inner surface of the connecting part 304. Correspondingly, metal sheets or magnetic materials that attract each other are embedded in the groove wall of the step groove 501 of the jigsaw board body 10. When the connecting part 304 is embedded in the step groove 501, the magnetic attraction components attract each other to generate a magnetic connection force. During this process, the connecting part 304 is firmly attached to the step groove 501 under the action of the magnetic force, and at the same time, this stable acting force will be transmitted. Since the connecting part 304 and the pressing part 303 are of an integral structure, the stability of the connecting part 304 will drive the pressing part 303 to act on the working layer 40 more closely, giving the pressing part 303 an additional pressure, so that the pressing part 303 can better press the working layer 40 tightly on the placement plane of the boss structure 50, preventing the working layer 40 from shifting or wrinkling.

[0061] In Embodiment 2 of the present invention, the frame 30 encloses to form a slot 502 corresponding to the working layer 40, and a cover plate 60 detachably connected to the jigsaw board body 10 is arranged on the slot 502; When no jigsaw operation is carried out, the cover plate 60 is tightly pressed on the working layer 40 in the slot 502 to fix the jigsaw on the working layer 40. Preferably, the cover plate 60 is magnetically matched with the jigsaw board body 10.

[0062] The main purpose of arranging the detachably connected cover plate 60 on the slot 502 formed by the frame 30 enclosing the corresponding working layer 40 is to protect the assembled jigsaw on the working layer 40 when no jigsaw operation is carried out. When the cover plate 60 is placed on the slot 502, it will exert a certain pressure on the working layer 40 by virtue of its own gravity and the magnetic force generated by the magnetic matching with the jigsaw board body 10. This pressure can effectively prevent the jigsaw pieces from shifting or scattering due to external force collision, vibration or accidental touch, and will not damage the jigsaw or the working layer 40 due to excessive pressure. The cover plate 60 is designed to be magnetically matched with the jigsaw board body 10, making use of the convenience and stability of the magnetic force. When the cover plate 60 needs to be covered or removed, the user only needs to approach or move away gently, and the magnetic force can achieve quick connection and separation. At the same time, the magnetic force can ensure that the cover plate 60 is accurately aligned with the slot 502 when placed, and maintains a stable pressure application state during use, continuously providing reliable protection for the jigsaw. Among them, the cover plate 60 can be a flexible plate with magnetic ability, and corresponding magnetic components for cooperating with the cover plate 60 are arranged inside the position of the inner slot of the jigsaw board body 10 (distinguished from the permanent magnet components at the edge of the jigsaw board body 10 in terms of spatial position, so as to avoid magnetic attraction conflict).

[0063] This design is closely adapted to the puzzle operation process. During the puzzle-solving process, users can easily remove the cover plate 60 and place it aside without causing any obstruction to the puzzle operation. When the puzzle is temporarily interrupted or a part needs to be saved during the process, the cover plate 60 can be quickly magnetically installed on the slot 502 to apply appropriate pressure to the puzzle on the working layer 40 for proper protection, seamlessly connecting different stages of the puzzle and providing users with a convenient and efficient puzzle experience.

[0064] Please refer to Figures 13-17 , Embodiment 3, a puzzle board with a rotatable drawer, comprising a puzzle board body 10, wherein a rotatably connected drawer 20 is provided on the puzzle board body 10, and the drawer 20 can extend out of the puzzle board body 10 or be received into the puzzle board body 10 during rotation.

[0065] In the technical solution of this Embodiment 3, a rotatably connected drawer 20 is added to the puzzle board body 10. From the perspective of mechanical structure principle, through a specific rotary connection device, such as a hinge or a rotating shaft 102, etc., the drawer 20 is connected to the puzzle board body 10, enabling the drawer 20 to perform circular motion around the connection point. This design allows the drawer 20 to flexibly switch positions between the inside and outside of the puzzle board body 10, providing a spatial basis for fragment storage; The drawer 20 is designed to be rotatable rather than the traditional straight-pull type to better adapt to the puzzle scenario. Specifically, during the puzzle-solving process, the space around the player may be limited, and the straight-pull drawer 20 may not be fully opened due to space obstruction, affecting the convenience of accessing the fragments. However, the rotatable drawer 20 only occupies a small arc space during rotation and can smoothly extend out in a limited space, facilitating the player to pick up the fragments. At the same time, the rotation action is more flexible than the straight pull. The player can easily open the drawer 20 from different angles, which conforms to the ergonomic principle and reduces the operation difficulty; In summary, this Embodiment 3 can effectively: Solve the problem of fragment storage: This puzzle board effectively solves the problem that traditional puzzle boards lack the function of fragment storage. Players no longer need to find additional containers to hold the puzzle fragments. They can directly place the fragments in the drawer 20 in categories. The storage in the drawer 20 makes the fragments concentrated, greatly reducing the risk of fragment scattering and loss, and avoiding the situation where the puzzle cannot be completed due to missing fragments; for example, during a family gathering, when multiple people participate in a puzzle game, the puzzle board with the rotatable drawer 20 allows everyone to conveniently store the fragments in it. Even if the game is interrupted, there is no need to worry about the fragments being in a mess and getting lost; Enhance the puzzle operation experience: During the puzzle-solving process, the drawer 20 can be rotated to facilitate players in quickly locating the required pieces. Players can classify the pieces according to their shapes, colors and other characteristics and place them in different areas of the drawer 20 or different drawers 20. When needed, they can quickly find the corresponding pieces without rummaging through a large number of disordered pieces one by one, saving time, maintaining the coherence of the puzzle-solving train of thought, and enhancing the smooth experience and fun of the puzzle. For example, when completing a complex puzzle of thousands of pieces, rotating the drawer 20 allows players to quickly find the edge pieces or specific pattern pieces, accelerating the puzzle-solving process. Save space and convenient storage: After the puzzle game is over, the rotatable drawer 20 can be stored inside the puzzle board body 10, reducing the overall space occupied. Compared with the traditional way of using a puzzle board with an additional storage container, this integrated design is more convenient for daily storage, especially suitable for users with limited living space. Whether placed on a bookshelf, in a cabinet or under a table, it can effectively save space and make the home environment more tidy and orderly.

[0066] In Embodiment 3 of the present invention, the puzzle board body 10 is provided with an internal slot 101 for storing the drawer 20. The drawer 20 is rotatably connected to the puzzle board body 10 through a rotating shaft 102 so as to be able to extend out of the internal slot 101 around the rotating shaft 102 or be stored in the internal slot 101.

[0067] The internal slot 101 for storing the drawer 20 is considered based on the efficient use of space and the storage stability of the drawer 20. From the perspective of space design, the sizes of the internal slot 101 and the drawer 20 are precisely adapted to ensure that when the drawer 20 is in the storage state, it can perfectly fit with the puzzle board body 10. This not only makes the overall appearance of the puzzle board more regular, but also effectively prevents the drawer 20 from shaking randomly when not in use, affecting the placement stability of the puzzle board. At the same time, the existence of the internal slot 101 provides a dedicated storage space for the drawer 20, so that when the puzzle board is not in use, the overall occupied space is only the area of the puzzle board body 10, achieving the maximization of space utilization. The drawer 20 is rotatably connected to the puzzle board body 10 by using the rotating shaft 102 to achieve stable and flexible rotation operation of the drawer 20. As the core connecting component, the rotating shaft 102 has good rotating performance and can bear the weight and external force of the drawer 20 during the rotation process. By installing the rotating shaft 102 at a preset position, the drawer 20 can make a circular motion around the rotating shaft 102 and smoothly extend out of or be stored back into the internal slot 101. Compared with other connection methods, such as simple hinge connection, this connection method can better ensure the stability of the drawer 20 during the rotation process, reduce shaking and deviation, and provide a reliable operation experience for users.

[0068] In Embodiment 3 of the present invention, a central hole 201 is provided at the center of the drawer 20. At both ends of the built-in groove 101 corresponding to the position of the central hole 201 of the drawer 20, shaft holes 104 adapted to the rotating shaft 102 are respectively opened, and the rotating shaft 102 sequentially passes through the shaft hole 104 at one end, the central hole 201 of the drawer 20, and the shaft hole 104 at the other end.

[0069] Shaft holes 104 adapted to the rotating shaft 102 are opened at both ends of the built-in groove 101 corresponding to the central position of the drawer 20 to achieve precise positioning of the installation of the drawer 20. From the perspective of the mechanical installation principle, the precise matching of the shaft hole 104 and the rotating shaft 102 ensures that the rotating shaft 102 can be installed along a specific trajectory, enabling the drawer 20 to rotate stably around a predetermined central axis after installation; by setting the shaft holes 104 at the positions corresponding to the center of the drawer 20, the force on the drawer 20 during rotation is ensured to be uniform, avoiding shaking or jamming of the drawer 20 during rotation due to installation deviation, laying a foundation for the stable operation of the drawer 20; the rotating shaft 102 sequentially passes through the shaft hole 104 at one end, the central hole 201 of the drawer 20, and the shaft hole 104 at the other end, forming a stable rotating support structure. The tight fit between the shaft hole 104 and the rotating shaft 102 not only provides a rotating fulcrum for the drawer 20 but also can withstand various forces generated during the rotation of the drawer 20, including gravity, inertia force, and external force applied by the player during operation. This design enables the drawer 20 to always maintain a stable rotating state during frequent opening and closing processes, ensuring the normal use of the puzzle board.

[0070] In Embodiment 3 of the present invention, the drawer 20 is a semi-circular structure rotatable about the rotating shaft 102; The built-in groove 101 is in a semi-circular shape adapted to the drawer 20.

[0071] Designing the drawer 20 as a semi-circular structure rotatable about the rotating shaft 102 and making the built-in groove 101 in a semi-circular shape adapted thereto is based on considerations of efficient space utilization and structural matching. Specifically, from the perspective of the space design principle, the semi-circular structure can maximize the use of the area of the built-in groove 101 for fragment storage within the limited space of the puzzle board body 10. Compared with the designs of square or other-shaped drawers 20 and built-in grooves 101, the semi-circular structure can better fit the internal space contour of the puzzle board, reducing space waste. Moreover, this adapted shape design makes the contact between the drawer 20 and the built-in groove 101 closer and smoother during rotation, ensuring the stability and smoothness of the rotation of the drawer 20; The semi-circular drawer 20 designed with the rotating shaft 102 as the center conforms to the principle of rotational dynamics. Specifically, the center of gravity distribution of the semi-circular shape is relatively uniform. When rotating around the rotating shaft 102, it can reduce the shaking and resistance caused by the center of gravity offset. When the player pushes the drawer 20 to rotate, the semi-circular structure makes the force more concentrated on the rotating shaft 102, reducing the force required for operation and improving the convenience of operation. At the same time, the semi-circular design of the built-in groove 101 also provides a suitable space range and guidance for the rotation of the drawer 20, further optimizing the rotation performance of the drawer 20.

[0072] In Embodiment 3 of the present invention, an arc-shaped track 103 is provided on the inner wall of the built-in groove 101, and the outer contour of the drawer 20 fits with the arc-shaped track 103, so that the drawer 20 can slide smoothly along the arc-shaped track 103 when rotating around the rotating shaft 102.

[0073] The purpose of setting the arc-shaped track 103 on the inner wall of the built-in groove 101 is to provide precise sliding guidance and stable support for the rotation of the drawer 20. From the perspective of the principle of mechanical motion, the arc-shaped track 103 fits with the outer contour of the drawer 20, which can ensure that the drawer 20 always moves along the established arc trajectory during the rotation around the rotating shaft 102. This guiding effect avoids the deviation or shaking of the drawer 20 during rotation, ensuring the stability of the operation of the drawer 20. At the same time, the arc-shaped track 103 can disperse the pressure borne by the drawer 20 during rotation, providing continuous and uniform support force, making the drawer 20 rotate more smoothly and effectively reducing the jamming phenomenon caused by uneven local stress. When the outer contour of the drawer 20 fits and slides with the arc-shaped track 103, the friction force formed between the two is more stable and controllable compared with the situation without a track. A reasonably designed arc-shaped track 103 can reduce the friction coefficient and the resistance during the rotation of the drawer 20, making it easier for the player to push the drawer 20. From the perspective of the friction force principle, the surface contact method between the arc-shaped track 103 and the drawer 20 can distribute the friction force better than point contact or line contact, avoiding excessive local friction and wear on the drawer 20 and the track, thus improving the overall motion performance and service life of the drawer 20.

[0074] In Embodiment 3 of the present invention, a hinge structure 105 is provided along the central axis of the jigsaw board body 10, so that the jigsaw board body 10 can be folded in half. Among them, there are two drawers 20, which are respectively arranged in the built-in grooves 101 at both ends of the jigsaw board body 10. When the jigsaw board body 10 is folded in half through the hinge structure 105, the two drawers 20 are received with the corresponding built-in grooves 101 and approach each other.

[0075] An articulated structure 105 is provided along the central axis of the puzzle board body 10 to meet the user's requirement for the portability of the puzzle board. Starting from the product design concept, through the articulated structure 105 (such as a hinge), the puzzle board can be folded in half, significantly reducing its floor area when not in use. When the user needs to carry the puzzle board out, such as for an outdoor picnic, a parent-child activity, or a trip, the foldable design allows it to be easily placed in a backpack, a handbag, etc., facilitating transportation and storage. At the same time, two drawers 20 are respectively arranged in the built-in slots 101 at both ends of the puzzle board body 10, and they are close to each other for storage when the puzzle board is folded in half, further optimizing the space utilization. This design fully considers the storage needs of the puzzle pieces. Within the limited space of the puzzle board, by reasonably arranging the positions of the drawers 20, the storage capacity is maximized, and at the same time, the stability of the drawers 20 and the internal pieces is ensured in the folded state.

[0076] In Embodiment 3 of the present invention, a plurality of partition structures 202 are arranged inside the drawer 20 to divide the interior of the drawer 20 into a plurality of independent material placement areas 203 through the plurality of partition structures 202.

[0077] The arrangement of a plurality of partition structures 202 inside the drawer 20 is to meet the actual needs of classifying and managing the pieces during the puzzle-solving process. Puzzle pieces usually have different shapes, colors, and patterns. During the puzzle-solving process, players need to quickly find specific pieces. By dividing the interior of the drawer 20 into a plurality of independent material placement areas 203 through the partition structures 202, players can store the pieces according to their characteristics. This design draws on the zoning concept in warehouse management, reasonably planning the originally chaotic piece storage space, so that each area has its specific use, thereby improving the efficiency of piece management. From the perspective of space utilization, the arrangement of the partition structures 202 optimizes the internal space layout of the drawer 20. Puzzle pieces of different sizes and shapes can be adaptively placed according to the size of the partitioned areas, avoiding the messy accumulation of pieces in the drawer 20. Each partitioned area becomes a relatively independent storage unit, making full and reasonable use of the internal space of the drawer 20. This orderly space planning not only helps improve the storage efficiency but also reduces the mutual extrusion and collision between the pieces, protecting the pieces from damage.

[0078] In Embodiment 3 of the present invention, the partition structure 202 is a placement tray, and the shape of the placement tray is adapted to the internal contour of the drawer 20. Among them, the placement tray can be taken out from the drawer 20.

[0079] The partition structure 202 is designed as a placement tray with a shape adapted to the inner contour of the drawer 20 and can be taken out of the drawer 20, aiming to meet the flexible needs and personalized customization of users for storage methods. Different users have different criteria for sorting puzzle pieces when doing puzzles. The removable placement tray allows users to freely adjust the size and layout of each feeding area 203 according to their own habits. For example, for a complex portrait puzzle, some users may hope to place the pieces of different figures in separate placement trays, while some users may classify the pieces according to color. This design gives users the right to decide independently, greatly improving the flexibility of the storage method and better fitting the personalized puzzle-solving habits of users. From the perspectives of product use convenience and maintenance, the design of the removable placement tray makes the cleaning work easier. During the puzzle-solving process, the placement tray is prone to being contaminated with dust, stains, etc. Especially in a home use scenario, when children are involved in puzzle-solving, the placement tray may be soiled with food residues, etc. The removable design allows users to directly take out the placement tray from the drawer 20 for separate cleaning, avoiding the inconvenience of cleaning the inside of the drawer 20 and ensuring that the storage space always remains clean and tidy, providing a good storage environment for puzzle pieces.

[0080] At the same time, the feature that the placement tray can be taken out separately can greatly improve the instant use convenience of the puzzle board. Specifically, when players are doing puzzles, they can directly hold the placement tray loaded with the corresponding puzzle pieces to play the puzzle game.

While each plays its own advantages, it will not interfere with other functions, jointly creating a puzzle tool with both convenience and functionality for users, and comprehensively meeting the diverse needs of modern users for puzzles in different scenarios; Furthermore: The core design that can be folded around the puzzle board body 10 realizes the perfect coordination of the three major functional modules: the bracket assembly 70, the magnetic border 30, and the rotating drawer 20. Specifically, the puzzle board body 10 can be folded in half along the central axis, greatly improving portability and storage convenience. The slot 81 of the bracket assembly 70 corresponds to the folding position, which is easy to disassemble when folding to avoid obstruction. When unfolded, the connecting piece 73 is inserted into the slot 81 to inhibit rotation around the folding axis, ensuring that the first movable bracket 71 adjusts the angle to improve light and relieve neck fatigue. The second movable bracket 72 constructs a placement position, and is firmly connected and easy to maintain. The magnetic border 30 is divided into two halves along the central axis. When folding, the docking continuously presses the felt working layer 40 to maintain stable function. At the same time, the magnetic component ensures quick connection, and the boss cooperates with the border 30 to press firmly. The magnetic cover 60 protects the assembled part. The rotating drawer 20 is located at both ends (left and right sides) of the puzzle board. When folding in half, they approach each other to optimize space utilization. The semi-circular design cooperates with the arc track 103 to rotate smoothly. The internal removable partition placement tray facilitates the classification of pieces, does not affect folding, and improves storage and cleaning convenience. Each module is linked by the folding design of the puzzle board, complementing each other in different states, bringing users a convenient and feature-rich puzzle experience, highly meeting the needs of modern diverse scenarios.
