Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Referring to fig. 1, 2, 3, 6, 7 and 8, an embodiment of the present invention provides a magnetic building block, including a block body formed by splicing a plurality of magnetic polyhedrons 1, where each magnetic polyhedron 1 has an inner end face 11, an outer end face 12 and a plurality of splicing side faces 13, the inner end face 11 is disposed opposite to the outer end face 12, the inner end face 11 has a plurality of sequentially connected first edges 111, the outer end face 12 has a plurality of sequentially connected second edges 121, the splicing side faces 13 are connected between the first edges 111 and the second edges 121, the polarity of the inside end face 11 is opposite to the polarity of the outside end face 12, the polarity of the splicing side face 13 close to the first edge 111 is the same as that of the inside end face 11, the polarity of the splicing side face 13 close to the second edge 121 is the same as that of the outside end face 12, and two adjacent magnetic polyhedrons 1 are bonded to each other by the corresponding splicing side faces 13.

In the embodiment of the present application, the shape of the magnetic building block may be a cube, a cuboid, or a polyhedron (such as a triangular prism, a hexagonal prism, etc.) with other shapes, which are not specifically limited, and for convenience of description, the embodiment of the present application explains the shape of the magnetic building block as a cube.

In this embodiment, since the inner end face 11 and the outer end face 12 of the magnetic polyhedrons 1 have opposite polarities (that is, the inner end face 11 is an N pole, the outer end face 12 is an S pole, or the inner end face 11 is an S pole, and the outer end face 12 is an N pole), and the inner end face 11 and the outer end face 12 which are oppositely arranged are connected by the splicing side face 13, so that the splicing side face 13 can simultaneously have both polarities of an N pole and an S pole, and thus the adjacent magnetic polyhedrons 1 can simultaneously have both polarities of an N pole and an S pole by using the splicing side face 13, and splicing is realized by the principle of "opposite attraction" (that when the polarity distribution of one of the magnetic polyhedrons 1 is that the inner end face 11 is an N pole and the outer end face 12 is an S pole, the polarity distribution of the other magnetic polyhedron 1 can be designed such that the inner end face 11 is an S pole, a magnetic polyhedron 1, The outer side end face 12 is N-pole as shown in fig. 7), and finally a complete building block body can be spliced, for convenience of explanation, as shown in fig. 8 for example, in some embodiments, when the polarity distribution of the six outer surfaces (i.e. the six outer side end faces 12) of the building block body is "3N 3S", the building block body can be spliced by six independent magnetic polyhedrons 1 in a "six-in-one" combination manner, and the assembly is very convenient, it should be noted that, in this manner, the finally spliced building block body has four "edge slits" (two of which are shown in fig. 8) because the "opposite attraction" logarithm of the spliced side faces 13 is greater than the "opposite attraction" logarithm of the spliced side faces 13 (as shown in fig. 8, the "opposite attraction" logarithm of the spliced side faces 13 is 8 pairs, the number of pairs of "like poles repel" is 4 pairs), so that the stability of the block main body is not affected even if the finally spliced block main body has the "edge gap", and in some embodiments, in order to make the final magnetic block more compact and beautiful, the "edge gap" of the block main body can be eliminated by means of a binding tape and the like on the outer surface of the block main body.

In this embodiment, this magnetic building block is opposite through designing a plurality of "inside and outside terminal surface polarity that possess, concatenation side 13 has the magnetism polyhedron 1 of the characteristic of two kinds of polarities" concurrently, during the equipment, only need utilize the magnetism of magnetism polyhedron 1 itself, laminate through the concatenation side 13 that corresponds between two liang of adjacent magnetism polyhedrons 1, can assemble the magnetic building block that forms and satisfy the user demand, need not extra spare part, also need not to be in the building block main part or building block main part edge waiting position setting is used for inlaying or installing the mounting structure of permanent magnet, therefore this magnetic building block is convenient not only to assemble, moreover, the steam generator is simple in structure, and is low in cost.

Referring to fig. 1, 9 and 10, in an alternative embodiment, the magnetic building block further includes a connecting member 2 disposed in the block main body and detachably connected to the block main body, the plurality of inner side end faces 11 are provided with first connecting holes 112, the connecting member 2 has a plurality of first connecting heads 21 matched with the first connecting holes 112, and two adjacent and/or oppositely disposed magnetic polyhedrons 1 are connected into a whole through the matching between the first connecting holes 112 and the first connecting heads 21.

In this embodiment, a mode of disposing a connecting element 2 in a building block main body can be used to overcome a phenomenon of mutual repulsion between magnetic polyhedrons 1 during an assembly process, and obtain a magnetic building block with more diverse polarity distribution and a more compact structure, wherein the first connecting head 21 and the first connecting hole 112 may be square, circular or other shapes, which is not specifically limited, as long as the first connecting head 21 and the first connecting hole 112 can overcome a magnetic repulsion possibly existing between two adjacent or oppositely disposed magnetic polyhedrons 1 after being matched; in some embodiments, the first connection holes 112 may be formed in the inner side end surface 11 of each magnetic polyhedron 1 regardless of the polarity distribution of each magnetic polyhedron 1, and accordingly, the first connection joints 21 of the connection member 2 are adaptively designed according to the position distribution of the first connection holes 112, as shown in fig. 1 and 10, if the number of the first connection holes 112 is six, six first connection joints 21 may be designed on the connection member 2, and each first connection joint 21 corresponds to one first connection hole 112, so that, no matter what type the polarity distribution of the magnetic building block is as in fig. 9a to 9j, six independent magnetic polyhedrons 1 may be assembled into a compact and aesthetic magnetic building block; in other embodiments, the polarity distribution of each magnetic polyhedron 1 may also be considered, and only the inner side end faces 11 of at least two magnetic polyhedrons 1 that need to overcome the magnetic repulsion force are provided with the first connection holes 112, for convenience of description, taking fig. 8 as an example, the first connection holes 112 may be provided on the inner side end faces 11 of the upper and lower magnetic polyhedrons 1, and the first connection holes 112 may not be provided on the inner side end faces 11 of the remaining four magnetic polyhedrons 1, and accordingly, the connection member 2 may be designed with two corresponding first connection joints 21, so that not only "edge gaps" between the magnetic polyhedrons 1 due to the magnetic repulsion force may be eliminated, and a magnetic building block with a more compact and attractive structure may be obtained, but also the structure of the connection member 2 may be simplified and the number of processed first connection holes 112 may be reduced, thereby facilitating reduction; in addition, in other embodiments, by arranging the connecting pieces 2 in the block main body, not only the phenomenon of mutual repulsion possibly existing between the magnetic polyhedrons 1 in the assembling process can be overcome, and the magnetic block with more diversified polarity distribution and more compact structure can be obtained, but also the assembling manner can be more flexible, as shown in fig. 2 and 3, three of the magnetic polyhedrons 1 which are connected in sequence or two of the magnetic polyhedrons 1 can be considered to be integrated, and then the block main body is spliced in a 3+1 combining manner, of course, based on the inventive concept that the magnetic blocks are formed by splicing a plurality of the magnetic polyhedrons 1 in the block main body, in other embodiments, similar to the 3+1 combining manner, a 2+1 combining manner can be considered (i.e., after four of the magnetic polyhedrons 1 which are connected in sequence or two of the magnetic polyhedrons 1 are integrated, and then spliced with the other two separate magnetic polyhedrons 1), even in a combination manner of "1 + 1" (i.e., five of the two connected magnetic polyhedrons 1 are integrated and then spliced with the other one separate magnetic polyhedron 1), the principle and process thereof are similar to the combination manner of "3 + 1", and those skilled in the art can understand that details are not repeated here.

It should be noted here that, in the field of permanent magnet manufacturing, in order to obtain the largest possible magnetic performance of the permanent magnet, when manufacturing the permanent magnet, the selection of the magnetizing direction needs to be considered (i.e. the orientation problem needs to be considered, such as thickness orientation, radial orientation, etc.), therefore, when a plurality of connected magnetic polyhedrons 1 are made into a magnet of an integrated structure, the polarity of each outer side end face 12 of the obtained magnet is the same (such as all S poles or all N poles), and the situation that the polarities of the outer side end faces 12 are different does not occur, for example, when 3 connected magnetic polyhedrons 1 are made into a magnet of an integrated structure, the polarities of 3 outer side end faces 12 of the obtained magnet are all S poles or all N poles, and the situation that the polarity of the outer side end faces 12 is "2N 1S" or "2S 1N" does not occur (because it is still difficult to achieve with the level of the current permanent magnet manufacturing process), therefore, when a plurality of connected magnetic polyhedrons 1 are made into a magnet with an integrated structure, the polarity of each outer side end face 12 of the magnet is not determined at will according to requirements, which has limitations of the technical level and needs to consider the orientation problem, and those skilled in the art can understand that the description is not repeated.

It should be noted that, in other embodiments, in order to overcome the phenomenon of mutual repulsion between the magnetic polyhedrons 1 during the assembly process and obtain a magnetic building block with more diverse polarity distributions and a more compact structure, a manner of providing the connecting member 2 in the building block body and combining the connecting hole and the connecting head on the splicing side 13 may also be adopted, and those skilled in the art will understand that the description is omitted here.
