[0031] Please refer to Figures 1 to 5 , shows a magnetic attraction structure for a toy provided by one embodiment of the present invention, comprising a base 10, a housing 20, and a cover 30 mounted therebetween. A magnet 40 is connected to the cover 30. In this embodiment, the magnet 40 has two magnetic poles with opposite magnetic properties. In other embodiments of the present invention, the magnet 40 may also have a single magnetic pole.

[0032] The base 10 is provided with a groove 11 for fixing and installing the housing 20 so that a sealed receiving space can be formed between the groove 11 and the housing 20 to install the cover 30 and the magnet 40 in the receiving space.

[0033] In this embodiment, a supporting block 12 protrudes from the inner wall of the groove 11 at a position directly opposite the magnet 40. The supporting block 12 and the magnet 40 can be connected in a contacting manner to limit the lowest position of the magnet 40 in the groove 11, thereby preventing the magnet 40 from directly contacting the bottom wall of the groove 11. The supporting block 12 can also be used to position and connect the cover 30 in the groove 11. It should be noted that the sum of the heights of the supporting block 12 and the magnet 40 is less than the depth of the groove 11, so that the magnet 40 can move up and down in the groove 11 when subjected to magnetic force or gravity.

[0034] A stop ring 13 protrudes from the outer side of the open end of the base 10. This stop ring 13 limits the placement of the magnetic structure within the toy, speeding up installation. Specifically, the stop ring 13 can be fixedly connected to the outer wall of the toy, allowing the open end of the base 10 to be exposed on the outer wall of the building block. In other embodiments of the present invention, the base 10 may not be provided with the support block 12 and / or the stop ring 13.

[0035] The shell 20 is provided with a first cylinder 21 and a second cylinder 22, and the first cylinder 21 is located in the second cylinder 22. In this embodiment, the first cylinder 21 and the second cylinder 22 are concentrically arranged on the shell 20, and the first cylinder 21 extends upward along the bottom wall of the second cylinder 22. The first cylinder 21 is an axial through structure, and a sliding opening 211 is provided on the side wall of the first cylinder 21. The axial height of the second cylinder 22 is equal to the depth of the groove 11, and the second cylinder 22 is fixedly connected to the groove 11 by a buckling structure. With the above arrangement, when the second cylinder 22 is fixed in the groove 11 by the buckling structure, the open end of the first cylinder 21 and the open end of the groove 11 are basically located on the same plane, so as to ensure that when the two magnetic structures are connected, the gap between the two is small enough.

[0036] In other embodiments of the present invention, one end of the first cylinder 21 can be protruded outside the end wall of the first cylinder 22. With this structural arrangement, when the second cylinder 22 is fixed in the groove 11 through the buckling structure, the open end surface of the first cylinder 21 is parallel to the open end surface of the groove 11.

[0037] In this embodiment, the bottom wall of the second barrel 22 is formed with at least one insertion port 221, located on the outer ring of the first barrel 21. This insertion port 221 is used to connect securely to an external toy's plug-in rod. This arrangement allows the magnetic attraction structure to securely connect two toys (e.g., two toy building blocks) without the magnetic force of the magnet 40. In other embodiments of the present invention, the second barrel 20 may not have the insertion port 221.

[0038] The snap-fit ​​structure includes a snap body and an interface disposed between the second cylindrical body 22 and the groove 11. The snap body can be snapped into the interface. The snap-fit ​​structure allows the housing 20 to be quickly secured to the groove 11 during assembly by pressing the housing 20 into the groove 11. This provides a convenient and fast installation method, which helps to increase the installation speed of the magnetic structure.

[0039] In this embodiment, the buckle body includes a first buckle body 51 extending upward along the bottom wall of the groove 11. The interface includes a first interface 52 formed on the side wall of the second cylindrical body 22, corresponding to the first buckle body 51. The first buckle body 51 can be inserted between the first cylindrical body 21 and the second cylindrical body 22, so that the first buckle body 51 can be fastened to the first interface 52. It should be noted that the first buckle body 51 is provided with a protrusion 500 that protrudes toward the first interface 52. The protrusion 500 is an arcuate (or wedge-shaped) body and is used to snap the first buckle body 51 into the first interface 52. Specifically, because the first buckle body 51 includes a rod extending upward along the bottom wall of the groove 11, the rod can slightly deform when subjected to a compressive force until the protrusion 500 is aligned with the first interface 52, at which point the rod returns to its original position, completing the fastening operation.

[0040] In other embodiments of the present invention, for example Figure 6 and Figure 7In the second embodiment shown, the buckle body includes a second buckle body 53 disposed on the outer wall of the second cylindrical body 22, and the interface includes a second interface 54 formed on the side wall of the groove 11 corresponding to the second buckle body 53. When the second cylindrical body 22 is fully received in the groove 11, the second buckle body 53 can be buckled into the second interface 54. In the second embodiment, the entire second buckle body 53 is a protrusion 500, which is configured in a wedge-shaped structure to enable the second buckle body 53 to be more securely connected to the second interface 54. In other embodiments, the buckle body includes both a first buckle body 51 and a second buckle body 53, and the interface includes both a first interface 52 and a second interface 54.

[0041] It should be noted that the length of the protruding portion 500 in the first buckle body 51 is equal to or approximately equal to the length of the opening of the first interface 52, and the length of the protruding portion 500 in the second buckle body 53 is equal to or approximately equal to the length of the opening of the second interface 54. The above arrangement can limit the relative rotation of the housing 20 within the groove 11.

[0042] The cover body 30 is a hollow structure with at least one end open, so that the magnet 40 can enter the inner cavity of the cover body 30 through the open end of the cover body 30. In this embodiment, the inner cavity size of the cover body 30 is equal to or larger than the outer diameter of the magnet 40, so that the magnet 40 can be freely flipped in the inner cavity of the cover body 30, so that the magnetic pole of the magnet 40 facing the outer end can be flipped and transformed accordingly according to the different magnetic properties of the other magnet 40 connected to it. In other embodiments of the present invention, the inner cavity size of the cover body 30 can be smaller than the outer diameter of the magnet 40, so that the magnet 40 is fastened in the cover body 30. The magnetic attraction structure of this structure has only a single magnetic property and can only be magnetically fixed to another magnetic attraction structure with opposite magnetic properties.

[0043] The side wall of the cover body 30 protrudes with a slider 31 that is movably connected to the sliding port 211, so that the cover body 30 can move up and down in the first cylinder 21. A gear ring 32 is provided on one end wall of the cover body 30. The gear ring 32 can be pushed by the magnet 40 and exposed outside the first cylinder 21. The gear ring 32 can engage with the gear ring of another magnetic structure to achieve a tight connection between the two magnetic structures and prevent dislocation. It can be understood that the gear ring 32 is fixedly provided on the end wall of the cover body 30 and can move up and down with the cover body 30. On the one hand, when the two magnetic structures are separated, the gear ring 32 can be caused by gravity to fall back into the first cylinder 21, which can reduce the speed at which the gear ring 32 is damaged by wear and tear, thereby increasing the service life of the magnetic structure. On the other hand, it can also optimize the structure of the cover body 30, reduce the number of assembly parts of the magnetic structure, and help improve production and assembly efficiency.

[0044] In this embodiment, the cover 30 further defines a through hole 33 in the middle of the gear ring 32. The opening of the through hole 33 is smaller than the size of the magnet 40. This serves to increase the magnet 40's ability to sense external magnetic forces while preventing the magnet 40 from escaping the cover 30. In other embodiments of the present invention, the end wall of the cover 30 where the gear ring 32 is located may also be a closed structure.

[0045] To increase the tightness of the connection between the base 10 and the housing 20 and further prevent the housing 20 from rotating circumferentially within the base 10, in this embodiment, the base 10 and the second cylindrical body 22 are connected by a positioning structure. The positioning structure includes a positioning bar 61 and a positioning opening 62, which are respectively provided between the groove 11 and the second cylindrical body 22. The positioning bar 61 and the positioning opening 62 are shaped to match each other and can be plugged into each other. In other embodiments of the present invention, the positioning structure between the base 10 and the second cylindrical body 22 may not be provided.

[0046] When assembling the magnetic structure provided by the present invention, it is only necessary to place the magnet 40 in the cover body 30, place the cover body 30 in the first cylinder 21, and then press the base 10 and the second cylinder 22 toward each other to make the two buckle together. Compared with the existing structure, the assembly steps are fewer and the assembly process is simple and convenient, thereby effectively improving the production and assembly efficiency of the magnetic structure.

[0047] For clarity, certain features of the present invention described in the context of separate embodiments may be combined in a single embodiment. Furthermore, various features of the present invention described in the context of a single embodiment may also be used individually or in any suitable subcombination.
