Description

Technical Field

[0001] This application relates to the field of Rubik's Cube technology, and more particularly to a magnetic second-order Rubik's Cube. Background Technology

[0002] The Rubik's Cube, a classic puzzle toy, has been loved by people of all ages worldwide since its inception. It not only tests players' spatial reasoning and finger dexterity but also subtly cultivates logical thinking and problem-solving skills. The 2x2 Rubik's Cube, as a basic member of the Rubik's Cube family, with its simple structure and moderate difficulty, has become the first choice for many Rubik's Cube enthusiasts, whether starting out or progressing.

[0003] To improve the smoothness of operation and overall stability of the Rubik's Cube, magnetic components are embedded inside. The interaction between these magnetic components optimizes the feel and positioning accuracy during rotation. Although some existing 2x2 Rubik's Cubes have magnetic components that attract between the corner pieces and the center, they still suffer from slow reset speeds and inaccurate reset positions, significantly diminishing the playing experience.

[0004] Adding more magnets will inevitably improve the performance of the Rubik's Cube, but it will also significantly increase the selling price, which may not meet the purchasing standards of some people. Alternatively, the effect of magnets in certain parts may not suit the preferences of some users. However, changing the structure of the same Rubik's Cube simply by adjusting the presence or absence of magnets in a few areas will increase costs significantly in terms of design, plastic coating, and production lines.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0063] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0064] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0065] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0066] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0067] like Figures 1 to 10 As shown, this application provides a magnetic 2x2 Rubik's Cube, including a central body 1, multiple center blocks 2, multiple hidden edges 3, and eight corner blocks 4. The central body 1 is provided with multiple first magnetic components 5, and multiple long axes 11 are provided on the central body 1. Each center block 2 is respectively disposed on a corresponding long axis 11. Each hidden edge 3 is located around the central body 1, and each hidden edge 3 includes a main shell 31 and a locking foot 32. The locking foot 32 and the main shell 31 are detachably connected. The locking foot 32 includes a locking foot 32 with a second magnetic component 6 and a locking foot 32 without a second magnetic component 6. The locking foot 32 with the second magnetic component 6 and the locking foot 32 without the second magnetic component 6 are selectively connected to the main shell 31. Each corner block 4 is located outside the center blocks 2 and the hidden edges 3, and each corner block 4 is provided with a third magnetic component 7.

[0068] When the edge piece clip 32 used has a second magnetic component 6, in the reset state of the magnetic 2x2 Rubik's Cube, each first magnetic component 5 is positioned opposite the corresponding third magnetic component 7, and they are magnetically attracted to each other. During the rotation of the magnetic 2x2 Rubik's Cube, the second magnetic component 6 on the corresponding hidden edge 3 can be brought closer to the corresponding first magnetic component 5, and the first magnetic component 5 and the adjacent second magnetic component 6 are magnetically repelled.

[0069] The magnetic 2x2 Rubik's Cube provided in this application can be designed by setting multiple first magnetic components 5 on the center body 1 and third magnetic components 7 on the corner pieces 4. When the Rubik's Cube is in its reset state, each first magnetic component 5 is opposite to and magnetically attracted to the corresponding third magnetic component 7. This design can greatly improve the speed and accuracy of the Rubik's Cube's reset. At the same time, the magnetic repulsion between the second magnetic component 6 on the hidden edge 3 and the first magnetic component 5 during the rotation of the Rubik's Cube further enhances the reset of the corner pieces 4 during the rotation, further improving the speed and accuracy of the Rubik's Cube's reset and avoiding the rotational jamming phenomenon caused by excessive magnetic attraction.

[0070] Furthermore, the edge piece shell 31 and edge piece feet 32 ​​of the hidden edge 3 are detachably connected, and the edge piece feet 32 ​​include edge piece feet 32 ​​with a second magnetic component 6 and edge piece feet 32 ​​without a second magnetic component 6, and either one can be connected to the edge piece shell 31. This design allows players to flexibly choose whether to set magnetic components on the hidden edge 3 according to their personal preferences and actual needs, thus ensuring the smoothness and stability of the Rubik's Cube operation while also meeting the personalized needs of different players for magnetic settings. Moreover, since it is not necessary to replace a large structure due to whether or not magnets are set in some parts, there is no need to increase the cost in design, molding, and production line, making it more economical and efficient.

[0071] In some possible implementations, the main housing 31 of the prism block has an inner cavity 313, and a communicating groove 311 is formed on the main housing 311 communicating with the inner cavity 313. The prism block retainer 32 has a retainer body 321 and a retainer claw 322 connected to the retainer body 321. The retainer claw 322 passes through the communicating groove 311 and engages with the inner wall of the main housing 31. This structure allows the prism block retainer 32 to be securely connected to the main housing 31 of the prism block, while also facilitating disassembly and replacement. In actual operation, the prism block retainer 32 with or without the second magnetic component 6 can be easily installed onto the main housing 31 of the prism block through the communicating groove 311 as needed, thereby achieving personalized magnetic settings and different types of production.

[0072] In some possible implementations, the edge piece locking foot 32 includes two locking claws 322, each of which includes an extension body 3221 and a locking protrusion 3222 disposed at the end of the extension body 3221. The extension body 3221 is connected to the locking foot body 321, and the locking protrusions 3222 of the two locking claws 322 protrude in opposite directions. The locking protrusions 3222 on both locking claws 322 pass through the connecting groove 311 and respectively engage with the inner wall of the edge piece main shell 31. This double-claw design not only enhances the connection stability between the edge piece locking foot 32 and the edge piece main shell 31, but also effectively disperses the stress generated during engagement, avoiding loosening or damage that may be caused by single-point engagement. In practical applications, this structure can better withstand the various forces generated when the Rubik's Cube is rotated, ensuring a tight connection between the edge piece locking foot 32 and the edge piece main shell 31.

[0073] In some possible implementations, the inner wall of the edge piece shell 31 has a slot 312 that connects to the connecting groove 311. The slot 312 is an elongated opening, and the protrusions 3222 of the two claws 322 are located at both ends of the elongated opening along its length. This design allows the protrusions 3222 sufficient room to move within the slot 312, facilitating the installation and removal of the claws 322. Simultaneously, the elongated opening effectively prevents the protrusions 3222 from accidentally falling off during the Rubik's Cube's rotation.

[0074] In some possible implementations, the locking body 321 includes a first body 3211 and a second body 3212, with the claw 322 connected to the second body 3212. The first body 3211 is connected to the end of the second body 3212 opposite to the claw 322. The second body 3212 is inserted into the connecting groove 311, and the protrusion 3222 of the claw 322 extends out of the connecting groove 311 and engages with the inner wall of the edge block shell 31. If the edge block locking foot 32 has a second magnetic component 6, the second magnetic component 6 is disposed on the first body 3211. The second body 3212 is inserted into the connecting groove 311, and the outer wall of the second body 3212 fits against the inner wall of the connecting groove 311. This fitting design further enhances the stability of the connection between the edge block locking foot 32 and the edge block shell 31, reducing the possibility of noise and instability caused by component shaking during the rotation of the Rubik's Cube. Meanwhile, the second magnetic component 6 is placed on the first main body 3211, which not only facilitates the installation and replacement of the magnetic component, but also ensures its reasonable layout in the Rubik's Cube structure, so that the magnetic effect can be exerted more accurately, and the magnetic attraction and repulsion functions can be better realized during the Rubik's Cube reset and rotation, thereby improving the overall performance of the Rubik's Cube.

[0075] Furthermore, the first body 3211 has a mounting groove on the side opposite to the second body 3212, and the third magnetic component 7 is embedded in the mounting groove and is firmly bonded to the mounting groove with adhesive.

[0076] In some possible implementations, a flared groove 314 is provided on the outer wall of the main shell 31 of the prism block, and a connecting groove 311 is provided on the bottom wall of the flared groove 314. The cross-section of the flared groove 314 is larger than that of the connecting groove 311. The second body 3212 includes an insertion part 32121 and a insert 32122. The claw 322 is connected to the insertion part 32121, and the insert 32122 is located between the insertion part 32121 and the first body 3211. The insertion part 32121 is inserted into the connecting groove 311, and the insert 32122 is embedded in the flared groove 314. The design of the flared groove 314 provides a larger entry space for the installation of the insertion part 32121 and the claw 322 of the prism block foot 32, and plays a certain guiding role, so that the insertion part 32121 and the insert 32122 can enter the connecting groove 311 and the flared groove 314 more smoothly, improving the convenience and efficiency of installation. Meanwhile, the tight fit between the insert 32122 and the flared groove 314 can also play a limiting role, improving assembly accuracy. The fit between the insert 32122 and the claw 322 prevents the insertion part 32121 from shaking unnecessarily in the connecting groove 311, further enhancing the stability of the connection between the prism block claw 32 and the prism block main shell 31.

[0077] In some possible implementations, the center block 2 includes a central main block 22 and an annular rib 21 disposed on the side of the central main block 22 opposite to the central block 1. The annular rib 21 includes four main segments 211, which are arranged sequentially around the long axis 11, and adjacent main segments 211 are connected by an arc segment 212. During the rotation of the Rubik's Cube, the inner surface of the corner piece 4 slides into contact with the arc segment 212. The corner of the central main block 22 near the corner piece 4 is designed as an inward arc transition towards the side opposite to the corner piece 4. This arc transition design makes the contact between the corner piece 4 and the central main block 22 smoother during rotation, preventing the corner piece 4 from getting stuck when rotating through this point, preventing the cube from falling apart, and improving the player's experience.

[0078] In some possible implementations, the corner piece 4 has a corner piece shell 41 and a corner piece foot 42, which are connected. The third magnetic component 7 is mounted on the corner piece foot 42. The corner piece shell 41 has a recessed surface 411 on the side facing the center body 1. During the rotation of the Rubik's Cube, the recessed surface 411 of the corner piece 4 slides into contact with the arc segment 212. The design of the recessed surface 411 allows the corner piece 4 to better engage with the arc segment 212 of the ring rib 21 during rotation, reducing friction and resistance during rotation and improving the smoothness and stability of the Rubik's Cube's rotation.

[0079] In some possible implementations, the central main piece 22 has four right-angled portions 221, each of which protrudes a corresponding arc segment 212 radially along its major axis 11. Each right-angled portion 221 has two perpendicular planes 2211. The arc segment 212 protruding from the right-angled portion 221 ensures that the recessed corner piece 4 fits snugly with the arc segment 212, thus ensuring the stability and accuracy of the Rubik's Cube's rotation. Simultaneously, the right-angled portions 221 provide stronger structural support for the central main piece 22, making the entire Rubik's Cube more stable and less prone to deformation or damage when subjected to external forces.

[0080] In some possible implementations, the right-angled portion 221 has an inclined surface 222 on the side opposite to the central body 1. One side of the inclined surface 222 is close to the corresponding arc segment 212, and the other end of the inclined surface 222 extends to the end of the right-angled portion 221. The inclined surface 222 is configured to smoothly transition from the right-angled portion 221, avoiding the concave surface 411, and ensuring that the concave surface 411 is in contact with the arc segment 212, thus ensuring smooth rotation.

[0081] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
