Description

Technical Field

[0001] The present invention relates to the technical field of Rubik's Cubes, and in particular to a second-order six-axis Rubik's Cube learning machine. Background Art

[0002] A Rubik's Cube, also known as a Rubik's Cube. Common Rubik's Cubes include second-order Rubik's Cubes and third-order Rubik's Cubes. The existing third-order Rubik's Cube is a six-sided cube made of elastic hard plastic. The core is six axes and is composed of 26 small cubes. The third-order Rubik's Cube includes six center blocks, each with only one side colored; eight third-order corner blocks, with three different colors on three sides of the third-order corner blocks; and twelve edge blocks, with two different colors on two sides of the edge blocks. When the toy is in the initial position, the arrangement of the small cubes makes each side of the large cube have the same color, and these center blocks, edge blocks, and third-order corner blocks enclose an internal space. When a certain side of the large cube rotates translationally, the single color of its adjacent sides is destroyed, forming a new pattern cube, and further rotation results in further changes, forming a cube with each side composed of small squares of different colors. The gameplay is to quickly restore the scrambled cube to a single color on all six sides by rotating.

[0003] The existing second-order Rubik's Cube includes eight second-order corner blocks, with three different colors on three sides of the second-order corner blocks.

[0004] For existing second-order Rubik's Cubes, they all need to be manually scrambled and restored, and it is not conducive to Rubik's Cube learning to perform the actions of automatically displaying the Rubik's Cube. Therefore, when conducting Rubik's Cube teaching demonstrations, it hinders viewers from clearly observing the Rubik's Cube restoration process intuitively. The existing second-order Rubik's Cube structure is also not suitable for being controlled through an internal rotating shaft. Summary of the Invention

[0036] Now, example embodiments will be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0037] As Figures 1 to 9 shown, an embodiment of the present invention discloses a second-order six-axis Rubik's Cube learning machine. The second-order six-axis Rubik's Cube learning machine can automatically rotate under the control of an operator, so as to realize the automatic display of Rubik's Cube actions.

[0038] The second-order six-axis Rubik's Cube learning machine includes a third-order Rubik's Cube body 1, and also includes an installation base 2, an internal drive device, an inner support 4, an outer rotating shaft 5, eight second-order corner blocks 6 and a control system.

[0039] As Figure 2 shown, the structure of the third-order Rubik's Cube body 1 is the same as the related structure of the existing third-order Rubik's Cube, including six center blocks 11, twelve edge blocks 12 and eight third-order corner blocks 13. These center blocks, edge blocks and third-order corner blocks enclose an internal space in the shape of a sphere. The six center blocks 11 include five regular center blocks and one connecting center block.

[0040] As Figure 2 and Figure 3 shown, the installation base 2 is located outside the third-order Rubik's Cube body 1, and an external drive unit 21 is provided on the installation base 1. In this embodiment, the installation base 2 is located below the third-order Rubik's Cube body 1, and the inner support member 4 and the outer rotating shaft 5 are arranged vertically. In this embodiment, the inner support member 4 has a hollow channel that penetrates up and down and allows wires to pass through. The installation base 2 and the inner support member 4 can support the third-order Rubik's Cube body 1.

[0041] In addition to the setting method where the installation base 2 in this embodiment is located below the third-order Rubik's Cube body 1, the inner support member 4 can also be set in a horizontal state or above the third-order Rubik's Cube body 1 and other setting methods. When the manufacturing size of this second-order six-axis Rubik's Cube learning machine is small, it can be placed on a table. When the manufacturing size of this second-order six-axis Rubik's Cube learning machine is large, it can be placed in places such as a science and technology exhibition hall. At this time, the installation base 2 can be a movable or fixed base, or it can be a building structure such as a foundation, a wall, or a ceiling beam.

[0042] The internal drive device is arranged in the internal space of the third-order Rubik's Cube body 1 and includes a central frame 31 and five internal drive units 32. The five internal drive units 32 are arranged on the central frame 31; each internal drive unit 32 is connected to one of the conventional center blocks and can drive the conventional center block connected to the internal drive unit 32 to rotate. These five internal drive units 32 can include one or more of a servo motor, a stepper motor, or a continuously rotatable servo, and can drive the five conventional center blocks to rotate under the control of a control system. For example, referring to Figure 3 , the internal drive unit located at the top can drive the conventional center block located at the top to rotate, realizing the rotation of the center block, edge block, and third-order corner block on the top layer plane of the Rubik's Cube. The internal drive unit located on the right can drive the conventional center block located on the right to rotate, realizing the rotation of the center block, edge block, and third-order corner block on the right plane of the Rubik's Cube.

[0043] As Figure 3 shown, the central frame 31 includes an upper hemispherical shell 311 and a lower hemispherical shell 312 that are spliced and fixed together. Five installation slots for accommodating the internal drive units 32 are provided on the central frame 31. The upper hemispherical shell 311 and the lower hemispherical shell 312 can be connected together by buckles, screws, etc. The setting method of the five installation slots is that one is opened at the top of the upper hemispherical shell 311, and the remaining four are evenly distributed at the joint of the upper hemispherical shell 311 and the lower hemispherical shell 312. The central frame 31 can also be other structures such as a rectangular frame.

[0044] The first end of the inner support member 4 passes through and connects to the center block and is fixedly connected to the central frame 31, and the second end of the inner support member 4 is fixedly connected to the installation base 2.

[0045] The outer rotating shaft 5 is a hollow tubular structure sleeved on the inner support member 4. The first end of the outer rotating shaft is fixedly connected to the connecting center block; the second end of the outer rotating shaft 5 is power-connected to the outer driving unit 21 and can rotate under the drive of the outer driving unit 21. As Figure 3 shown, in this embodiment, the outer driving unit 21 is power-connected to the second end of the outer rotating shaft 5 through gear transmission. A driving gear 22 is provided on the rotating shaft of the outer driving unit 21, and a driven gear 23 is provided at the second end of the outer rotating shaft 5. In other embodiments of the present invention, the outer rotating shaft 5 and the outer driving unit 21 can also be connected by other known connection methods, such as through a belt, a coupling, etc. When the inner support member 4 is fixed, when the outer rotating shaft 5 rotates, it can drive the connecting center block located in the lower layer to rotate, thereby realizing the rotation of the central hole, edge block, and third-order corner block in the lower layer.

[0046] Each second-order corner block 6 is fixedly connected to one of the third-order corner blocks 13 to form a second-order six-axis Rubik's Cube. A gap for avoiding interference with the outer rotating shaft 5 is formed between two adjacent second-order corner blocks 6.

[0047] The control system is electrically connected to the outer driving unit 21 and the inner driving unit 32, and can control the outer driving unit 21 and the inner driving unit 32 to rotate by a specified angle to drive the center block to rotate, and drive the corresponding edge block and third-order corner block to rotate through the center block. When the third-order corner block 13 rotates, it can drive the second-order corner block 6 to rotate simultaneously, thus realizing the rotation of the second-order Rubik's Cube.

[0048] In this embodiment, the control system includes a touch screen 7 provided on the mounting base 2 and a controller provided in the mounting base 2. The touch screen 7 is electrically connected to the controller. The user can control this second-order six-axis Rubik's Cube learning machine through the touch screen 7. This second-order six-axis Rubik's Cube learning machine realizes the control of the second-order Rubik's Cube by driving the third-order Rubik's Cube body to rotate. Compared with the situation where the traditional second-order Rubik's Cube structure is not suitable for internal rotating shaft control, this second-order six-axis Rubik's Cube learning machine realizes the rotation of the second-order Rubik's Cube through the form of driving the third-order Rubik's Cube body to rotate by the inner driving device and the outer driving device, which can simplify the control method and structure, can automatically display the actions of the Rubik's Cube, and the solution is easy to implement.

[0049] As Figure 1 、 Figure 2 and Figure 9 shown, in this embodiment, the eight second-order corner blocks 6 are detachably connected to the eight third-order corner blocks 13. In this way, after removing the eight second-order corner blocks 6, this second-order six-axis Rubik's Cube learning machine can also be used as a third-order six-axis Rubik's Cube learning machine for teaching and demonstrating the third-order six-axis Rubik's Cube.

[0050] AsFigures 3 to 8 As shown in the figure, the third-order corner block 13 includes a corner block body 131 and a third-order right-angled cover plate 132 that are detachably connected by a magnetic connection assembly. The third-order right-angled cover plate 132 is located outside the corner block body 131; the second-order corner block 6 is connected to the corner block body 131 by a magnetic connection assembly. The magnetic connection assembly can include two magnetic blocks, or can include one magnetic block and one iron block. After removing the third-order right-angled cover plate 132 and connecting the second-order corner block 6 to the corner block body 131, the appearance of the third-order Rubik's Cube can be maintained beautifully.

[0051] The edge block 12 includes an inner-layer arc block 121 and an outer-layer right-angled block 122 that are detachably connected by a magnetic connection assembly. The top surface of the inner-layer arc block 121 is an arc surface, and this arc surface is lower than the third-order corner block 13. In this way, the second-order corner block 6 can be made as close as possible to the rotation axis of the center block 11 without interfering with the edge block 12. Of course, when the second-order corner block 6 is far from the rotation axis of the center block 11, it will not interfere with the edge block 12. At this time, the edge block 12 does not need to be set as the inner-layer arc block 121 and the outer-layer right-angled block 122.

[0052] On the side walls of the edge block 12 and the side walls of the third-order corner block 13, there can be magnetic blocks with corresponding positions that can attract each other. When the edge block 12 and the third-order corner block 13 approach each other, they can be automatically aligned through the mutual attraction of the magnetic blocks.

[0053] As Figures 3 to 6 shown in the figure, on the peripheral side walls of the center block 11, there are outwardly extending and surrounding the center block 11 flank skirt plates 111; the edge blocks 12 and the third-order corner blocks 13 around each center block 11 form a sliding fit with the flank skirt plates 111. A sliding groove 123 is provided on the inner-layer arc block 121 of the edge block 12, and a sliding plate 133 is provided at the lower end of the corner block body 131 of the third-order corner block 13, and a sliding groove 134 is formed above the sliding plate 133. The flank skirt plates 111 of the center block 11 and the edge block 12 and the third-order corner block 13 achieve a sliding fit through the sliding groove 123 and the sliding groove 134. By providing the flank skirt plates 111, when the center block 11 rotates, it can drive the edge block 12 and the third-order corner block 13 to rotate through the flank skirt plates 111, so that it is easier to overcome the resistance of the edge block 12 and the third-order corner block 13 and improve the reliability of rotation. When the size of this second-order six-axis Rubik's Cube learning machine is small, the resistance of the edge block 12 and the third-order corner block 13 is relatively small, and the flank skirt plates 111 can be cancelled, and only the contact effect between the side walls of the center block 11 and the edge block 12 and the third-order corner block 13 can be used to drive the rotation of the side walls and the edge block 12 and the third-order corner block 13.

[0054] In the two - order six - axis Rubik's Cube learning machine of this embodiment, the inner driving unit 32, the outer driving unit 21 and the control system can be powered by batteries, or the alternating current can be converted into direct current by the power module for power supply. The power module can be arranged in the installation base 2. Corresponding hollow channels or wire grooves and other structures are opened on the inner support member 4 to introduce the power line and the signal line from the installation base 2 into the internal driving device. When powered by batteries, the batteries can be arranged in the installation base 2 or in the internal driving device. The batteries can be rechargeable batteries and can be charged by wired or wireless charging methods.

[0055] The control system can use a single - chip microcomputer as the controller, or can also use control devices such as a tablet computer or an industrial control computer. The control system can be integrated on the installation base 2, or can be separately arranged from the installation base 2, and controls the outer driving unit and the inner driving unit through a cable or through a wireless transmission method such as WIFI. In addition, the touch screen can also be replaced by a touch - enabled device such as a smart phone or a tablet computer.

[0056] When the two - order six - axis Rubik's Cube learning machine of the embodiment of the present invention is in use, the operator can, by manipulating the control system, make the five inner driving units 32 and the outer driving unit 21 of the internal driving device rotate under the control of the control system, so as to realize the rotation of the two - order Rubik's Cube and automatically display the actions of the Rubik's Cube for the user to learn the operation method of the two - order Rubik's Cube.

[0057] The above specifically illustrates and describes the exemplary embodiments of the present invention. It should be understood that the present invention is not limited to the disclosed embodiments. On the contrary, the present invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
