Description
Technical Field
[0001] This utility model relates to the field of assembly toy technology, and in particular to a magnetic building block. Background Technology
[0002] Traditional building block toys typically connect through physical assembly. While simple, this method limits creativity and flexibility. To enhance the interactivity and creativity of building block toys, magnetic building blocks were developed. Magnetic building blocks use embedded magnets to connect and assemble the blocks using magnetic force, thus providing a new interactive experience.
[0003] However, existing magnetic building block designs have some problems. Specifically, in current magnetic structures, the magnet is generally fixedly embedded inside the block. This design requires a relatively large magnet to ensure sufficient magnetic force to maintain a stable connection between the blocks. Large magnets not only occupy more space but also increase material usage and production costs, thus requiring further improvement. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that magnets are generally fixed and embedded inside the building blocks, which requires the magnets to be large and take up a lot of space. Therefore, this invention proposes a magnetic building block.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] Design a magnetic building block, comprising at least one block;
[0007] The block has an opening on at least one end face, and a cover plate is connected to the block to cover the opening;
[0008] A connecting limiting frame is formed in the opening, and the connecting limiting frame and each corner of the block form an accommodating space, and a lifting part is formed in the accommodating space;
[0009] A magnetic suction element is placed in the accommodating space. The magnetic suction element moves above the lifting part. The connecting limiting frame, the lifting part and the cover plate form an active area for the magnetic suction element to move in space.
[0010] Furthermore, the connecting limiting frame includes multiple arc-shaped portions and multiple connecting portions, which are staggered and distributed in a ring shape.
[0011] The arc-shaped portion and the corner of the block form an accommodating space.
[0012] Furthermore, the end of the connecting part is provided with a hole, and the inner end of the cover plate is formed with a coupling post, which is tightly inserted into the hole.
[0013] Furthermore, the outer end of the connecting limiting frame is a predetermined distance from the side of the block to form an insertion port, and a positioning piece is also formed on the end face of the cover plate. The positioning piece is inserted into the insertion port and contacts the outer end of the connecting limiting frame.
[0014] The outer end face of the cover plate is flush with the side face of the block.
[0015] Furthermore, the two ends of the arc-shaped portion are respectively formed with a first stop portion and a second stop portion;
[0016] The first stop is used to limit the movement position of the magnetic attractor in the first direction;
[0017] The second stop is used to limit the movement of the magnetic member in the second direction.
[0018] Furthermore, the cover plate is used to restrict the movement of the magnetic member in a third direction, and the first direction, the second direction, and the third direction constitute the active domain.
[0019] Furthermore, in the first direction, the spacing between the magnetic elements in two adjacent blocks is smaller than the spacing between two adjacent first stops in a single block;
[0020] In the second direction, the spacing between the magnetic elements in two adjacent blocks is smaller than the spacing between two adjacent second stops in a single block.
[0021] Furthermore, the opening is configured in two parts and is located on two opposite end faces of the block, respectively;
[0022] In the third direction, the spacing between the magnetic elements in two adjacent blocks is smaller than the spacing between two opposing lifting parts in a single block.
[0023] Furthermore, the lifting part has a columnar structure and a lifting edge is formed at the upper end through a slot, and the magnetic suction component has a cuboid structure and is movably connected to the lifting edge.
[0024] Furthermore, the block is a cube with a side length of 1 cm.
[0025] The present invention proposes a magnetic building block with the following advantages: The design of the movable area allows for the spatial movement and rotation of the magnetic components, ensuring that when assembling another block in different orientations, the magnetic components can attract each other to achieve a magnetic connection. Simultaneously, the internal components of the block are separated by a connecting limiting frame and a lifting part, ensuring that the magnetic components in adjacent blocks can easily attract and connect when two or more blocks are magnetically assembled. Furthermore, the cover plate adopts a detachable connection design, further improving the convenience of assembly and subsequent maintenance. Because the magnetic components are movable, a smaller size can be designed while ensuring connection stability. The overall design is material-saving and ingenious, optimizing the applicability of existing building blocks. Attached Figure Description

Detailed Implementation
[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0033] Reference Figure 1-5 As one embodiment of this utility model, a magnetic building block is disclosed. Specifically, the building block includes at least one block 100. Obviously, those skilled in the art can assemble and splice multiple blocks 100 according to their needs to achieve the desired shape.
[0034] The block 100 has an opening 110 on at least one end face, and a cover plate 120 covering the opening 110 is connected to the block 100.
[0035] A connecting limiting frame 130 is formed in the opening 110, and the connecting limiting frame 130 and each corner of the block 100 form a receiving space 140. A lifting part 150 is formed in the receiving space 140.
[0036] Reference Figure 4 A magnetic suction component 160 is placed in the accommodating space 140. The magnetic suction component 160 moves above the lifting part 150. The connecting limiting frame 130, the lifting part 150 and the cover plate 120 form an active area for the magnetic suction component 160 to move in space. Specifically, in this embodiment, the design of the active area can be used to realize the spatial movement and rotation of the magnetic suction component 160, so as to ensure that when splicing another block 100 in different positions, the magnetic suction components 160 can attract each other to achieve magnetic connection.
[0037] In some embodiments, the connecting limiting frame 130 of this utility model includes a plurality of arc-shaped portions 131 and a plurality of connecting portions 132. The plurality of arc-shaped portions 131 and the plurality of connecting portions 132 are arranged in a staggered and circular pattern. The arc-shaped portions 131 and the connecting portions 132 adopt an integral molding structure design, which can improve the convenience of production by directly injection molding. Optionally, in this embodiment, four arc-shaped portions 131 and four connecting portions 132 are provided. The four arc-shaped portions 131 and the four corners of the block 100 constitute four accommodating spaces 140. Obviously, four magnetic suction components 160 should also be provided, so that free magnetic splicing can be achieved in multiple directions.
[0038] The curved portion 131 and the corner of the block 100 form an accommodating space 140.
[0039] Reference Figure 2 , Figure 3 Specifically, the end of the connecting part 132 in this utility model is provided with a hole, and the inner end of the cover plate 120 is formed with a coupling post 121. The number of coupling posts 121 is set to four. The coupling posts 121 are tightly inserted into the hole and are used to connect and fix the cover plate 120 by interference fit. The assembly and disassembly are simple and convenient.
[0040] Preferably, in this embodiment, the outer end of the connecting limiting frame 130 is a predetermined distance from the side of the block 100 to form an insertion port. A positioning piece 122 is also formed on the end face of the cover plate 120. The positioning piece 122 is inserted into the insertion port and contacts the outer end of the connecting limiting frame 130. In this embodiment, the positioning piece 122 is designed to guide and position the insertion position of the cover plate 120 when it is inserted. That is, when assembling the cover plate 120, the cover plate 120 can be fixed by aligning multiple positioning pieces 122 with the inside of the opening 110 and inserting them, and by interlocking the coupling post 121 with the above-mentioned hole. This improves the ease of installation of the cover plate 120.
[0041] The outer end face of the cover plate 120 is flush with the side face of the block 100. The flush design ensures the overall appearance consistency, thus achieving better aesthetics.
[0042] Based on the above embodiments, the two ends of the arc-shaped portion 131 in this utility model are respectively formed with a first stop portion 133 and a second stop portion 134. It should be noted that the first stop portion 133 and the second stop portion 134 in this embodiment are integrally formed with the arc-shaped portion 131 and protrude from one side of the connecting portion 132.
[0043] In this embodiment, the first stop 133 is used to limit the movement of the magnetic member 160 in the first direction, such as... Figure 4 As shown, the first direction in this embodiment is the length direction in the figure;
[0044] The second stop 134 is used to limit the movement of the magnetic member 160 in the second direction, of course, as Figure 4 As shown in the figure, the second direction in this embodiment is the height direction. The first direction and the second direction are perpendicular to each other, so as to limit the movement range of the magnetic suction member 160 in the plane.
[0045] Of course, in order to limit the magnetic chuck 160 in another direction within space, the cover plate 120 in this embodiment is used to restrict the movement of the magnetic chuck 160 in a third direction, such as... Figure 5 The third direction described in this embodiment, the first direction, the second direction, and the third direction constitute the activity domain.
[0046] It should be further explained that in this embodiment:
[0047] In the first direction, the distance between the magnetic elements 160 in two adjacent blocks 100 is smaller than the distance between two adjacent first stops 133 in a single block 100;
[0048] Specific examples Figure 4 As shown, in this embodiment, when two blocks 100 are magnetically joined, the distance between the two opposing magnetic members 160 in the first direction is L1, and the distance between the two adjacent first stop portions 133 in a single block 100 is L2. In this embodiment, the value of L1 is less than L2. This structural design is adopted to ensure that the magnetic members 160 in two adjacent blocks 100 can overcome the attraction of the two magnetic members 160 in a single block 100, so as to achieve the effect of mutual movement and adsorption. That is, when two blocks 100 are joined together, the magnetic members 160 on their opposing surfaces are smaller in distance, so they can attract each other to move and thus achieve magnetic fixation. This completes the magnetic assembly between two or more blocks 100.
[0049] In the second direction, the distance between the magnetic attractors 160 in two adjacent blocks 100 is less than the distance between two adjacent second stop portions 134 in a single block 100. Similarly, in this embodiment, when two blocks 100 are spliced together, the distance between the magnetic attractors 160 in the two blocks 100 in the second direction is W1, and the distance between the two second stop portions 134 in a single block 100 is W2. The value of W1 is less than that of W2. Thus, when two or more blocks 100 are spliced together, the magnetic attractors 160 on their opposite surfaces are more closely spaced, which allows them to attract each other and move, thereby achieving magnetic fixation.
[0050] The above is an example of magnetically assembling multiple blocks 100 along the first and second directions on a plane. Considering that magnetic assembly will also be performed in the third direction during actual assembly, the opening 110 in this embodiment is configured in two places and is located on two opposite end faces of the block 100 respectively.
[0051] In the third direction, the spacing between the magnetic elements 160 in two adjacent blocks 100 is smaller than the spacing between two opposing lifting portions 150 in a single block 100, such as... Figure 5 As shown, similarly in this embodiment, when two blocks 100 are spliced together, the distance between the magnetic suction members 160 in the two blocks 100 on the third direction is H1, and the distance between the two lifting parts 150 in a single block 100 is H2. The value of H1 is less than that of H2. Thus, when two or more blocks 100 are spliced together, the magnetic suction members 160 on their opposite surfaces are smaller in distance, so they can attract each other to move and thus achieve magnetic fixation.
[0052] Reference Figure 3It should be noted that, in this embodiment, the lifting part 150 has a columnar structure and a lifting edge 151 is formed at the upper end through a slot. The magnetic suction member 160 has a cuboid structure and is movably connected to the lifting edge 151. By designing the lifting edge 151, the contact area between the lifting part 150 and the magnetic suction member 160 can be reduced to reduce friction. This ensures that the magnetic suction member 160 can move and slide more conveniently and improves the action response efficiency of the magnetic suction member 160 during the magnetic suction process. Furthermore, preferably, in this embodiment, the magnetic suction member 160 is set as a cube permanent magnet. The length of the apex angle of the permanent magnet is less than or equal to the radius of the circular interval defined by the arc-shaped part 131. This ensures that the permanent magnet can rotate and rotate in the receiving space 140.
[0053] Furthermore, in this embodiment, the block 100 is a cube with a side length of 1 cm. By adopting a 1 cm size design, the overall size is smaller, which can achieve more detailed model mesh assembly. For example, in image assembly, since the size of the block 100 is small, smaller pixels can be achieved. The overall design saves materials and is ingenious.
[0054] In summary, the design of the movable area in this utility model allows for the spatial movement and rotation of the magnetic components 160. This ensures that when another block 100 is assembled in different positions, the magnetic components 160 can attract each other to achieve magnetic connection. At the same time, the internal connection limit frame 130 and lifting part 150 of the block 100 block act as a barrier between adjacent magnetic components 160, thus ensuring that when two or more blocks 100 are magnetically assembled, the magnetic components 160 in adjacent blocks 100 can be easily attracted and connected. Furthermore, the cover plate 120 adopts a detachable connection design, which further improves the convenience of assembly and subsequent maintenance. The overall design is material-saving and ingenious, optimizing the applicability of existing building blocks.
[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
