Description

Technical Field

[0001] The utility model relates to the technical field of magic cube, in particular to a portable magnetic positioning magic cube robot. Background Art

[0002] The Rubik's Cube is also called the Rubik's Cube. The existing three-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 three-order Rubik's Cube includes six center blocks, only one side of which has color; eight corner blocks, the three sides of which have different colors; and twelve edge blocks, the two sides of which have different colors. 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. These center blocks, edge blocks and three-order corner blocks enclose an internal space. When one side of the large cube rotates in translation, the single color of its adjacent sides is destroyed, and a new pattern cube is formed. It rotates and changes again, forming a cube with each side made up of small cubes of different colors. The way to play is to restore the scrambled cube to a single color on all six sides as quickly as possible by rotating it.

[0003] Existing Rubik's Cube robots use the movable arm and the rotating mechanism on the machine to rotate the Rubik's Cube to restore the Rubik's Cube. However, since the drive systems in each rotating mechanism operate independently, there are differences in the operation process, resulting in a certain angle deviation of the Rubik's Cube's cooperating claws, causing the rotating side to be misaligned and the next step of restoration to be stuck.

[0036] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0037] When designing a Rubik's Cube robot, the inventor of the present application found that the existing Rubik's Cube robot uses a movable arm and a rotating mechanism on the machine to rotate the Rubik's Cube to achieve the Rubik's Cube restoration work. However, since the drive systems in each rotating mechanism are operated independently, there are differences in the operation process, resulting in a certain angle deviation of the Rubik's Cube mating claws, causing the rotating side to be stuck when executing the next step of restoration without alignment.

[0038] In response to the above problems, an embodiment of the utility model provides a portable magnetic positioning Rubik's Cube robot, in which the magnet 41 can realize coaxial rotation with the rotating mechanism 3, and obtain the rotation angle of the rotating mechanism 3 through the magnetic positioning element 42, so that the Rubik's Cube robot can be fine-tuned during operation, thereby improving the rotation accuracy of the Rubik's Cube robot.

[0039] The technical solution of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] Figure 1 It is a schematic diagram of the overall structure of a portable magnetic positioning Rubik's Cube robot shown in an embodiment of the utility model.

[0042] Figure 2 It is an exploded schematic diagram of the movable arm 2 shown in the embodiment of the utility model.

[0043] Figure 3 It is another exploded schematic diagram of the movable arm 2 shown in the embodiment of the utility model.

[0044] See also Figures 1 to 3 The portable magnetic positioning Rubik's Cube robot provided by the embodiment of the utility model includes:

[0045] Machine 1;

[0046] A plurality of movable arms 2 are disposed around the outer peripheral surface of the machine platform 1;

[0047] A plurality of rotating mechanisms 3 are respectively arranged on the machine platform 1 and each of the movable arms 2;

[0048] The magnetic positioning component 4 includes a magnet 41 and a magnetic positioning element 42. The magnet 41 is arranged on the rotating mechanism 3. The magnet 41 rotates coaxially with the rotating mechanism 3. The magnetic positioning element 42 is arranged opposite to the magnet 41. The magnetic positioning element 42 collects the magnetic pole direction information of the magnet 41.

[0049] A plurality of movable arms 2 are arranged around the outer peripheral surface of the machine 1, forming a workspace for placing the Rubik's Cube. After the Rubik's Cube is placed in the workspace, the Rubik's Cube robot can restore the color blocks of the Rubik's Cube or disrupt the arrangement of the color blocks of the Rubik's Cube. The embodiment of the utility model takes the restoration of the color blocks of the Rubik's Cube as an example to explain the embodiment of the utility model in detail.

[0050] Specifically, when the portable magnetic positioning Rubik's Cube robot restores the color blocks of the Rubik's Cube, its working process is as follows: when the Rubik's Cube is placed in the workspace, the Rubik's Cube robot collects the colors of the current Rubik's Cube center block, edge block and third-order corner block, and drives the rotating mechanism 3 to rotate according to the built-in control logic of the Rubik's Cube robot, thereby driving the Rubik's Cube color blocks to rotate. When the rotating mechanism 3 rotates, the magnetic positioning element 42 collects information about the change in the magnetic pole direction of the magnet 41 that rotates coaxially with the rotating mechanism 3. After the magnetic positioning element 42 collects the magnetic pole direction information, it transmits the magnetic pole direction information to the Rubik's Cube robot. The Rubik's Cube robot controls the rotating mechanism 3 according to the magnetic pole direction information until the magnetic pole direction information collected by the magnetic positioning element 42 can correspond to the preset value. The magnet 41 and the magnetic positioning element 42 are arranged relative to each other, which can ensure that the magnetic positioning element 42 can detect a larger magnetic field of the magnet 41 and improve the accuracy of the detection.

[0051] In this embodiment, by using magnetic positioning detection on the rotating mechanism 3 of the Rubik's Cube machine, the rotation accuracy of the rotating mechanism 3 can be improved, and the fluency and reliability of the Rubik's Cube robot in restoring the Rubik's Cube can be improved.

[0052] The connection method between the movable arm 2 and the machine 1 belongs to the mature existing technology and is not limited in this application.

[0053] In one possible implementation, see Figure 4 The magnetic positioning element 42 of the portable magnetic positioning Rubik's Cube robot includes a Hall angle sensor 420 and a circuit board 421. The circuit board 421 is respectively arranged on the machine 1 and each of the movable arms 2. The Hall angle sensor 420 is connected to the circuit board 421. The Hall angle sensor 420 is located in the magnetic field of the magnet 41.

[0054] In a possible implementation, the Hall angle sensor 420 of the portable magnetic positioning Rubik's Cube robot includes a sensing element and an information processing element, wherein the sensing element is used to sense the magnetic pole direction information of the magnet 41, and the information processing element is used to output the rotation angle of the rotating mechanism 3 according to the magnetic pole direction information; the magnet 41 includes an annular radial magnet.

[0055] Specifically, the sensing element can collect the magnetic field signal of the magnet 41 and convert the magnetic field signal into a digital signal representing the current angle value. A magnetic collecting sheet (I MC) is provided in the sensing element, which can collect the magnetic field acting parallel to the surface of the sensing element and generate a vertical component proportional to the magnetic field at the edge of the I MC structure, and then measure this signal through two pairs of traditional planar magnetic positioning elements 42 located in the lower direction of the I MC. The placement directions of the two pairs of magnetic positioning elements 42 are perpendicular to each other and parallel to the surface of the sensing element (i.e., the X direction and the Y direction). Through such a structure, the actual angle can be encoded into two sinusoidal signals (cos and sin signals) with a phase difference of 90 degrees. The two sensed signals (Vx and Vy) proportional to the magnetic field strength will be amplified, sampled, and converted into digital signals. The two digital signals will calculate the angle through the inverse tangent function, which is realized by looking up a table, and the digital signal representing the current angle value will be converted into an analog signal through an information processing element.

[0056] In one possible implementation, see Figure 5 , the rotating mechanism 3 of the portable magnetic positioning Rubik's cube robot comprises a rotating shaft 31 and a Rubik's cube matching claw 32;

[0057] The magnet 41 and the magic cube matching claw 32 are connected to the axial end of the rotating shaft 31, and the magnet 41 and the magic cube matching claw 32 rotate coaxially with the rotating shaft 31. When the rotating shaft 31 rotates, the magic cube matching claw 32 can be driven to rotate, so as to realize the rotation of the magic cube color block. The magnet 41 and the magic cube matching claw 32 rotate coaxially with the magnet 41, which can ensure that the magnet 41 and the magic cube matching claw 32 have high stability when rotating, and can reduce the space occupied, so that the structure of the magic cube robot is more reasonable.

[0058] In one possible implementation, see Figure 3 The rotating mechanism 3 of the portable magnetic positioning Rubik's cube robot also includes a motor 33, a first gear set 34, a second gear set 35 and a transmission tooth 36. The rotating shaft 31 is provided with the first gear set 34 and the transmission tooth 36. The transmission tooth 36 is connected to the Rubik's cube matching claw 32 by transmission. The second gear set 35 is meshed with the first gear set 34 and the driving teeth of the motor 33 respectively. Specifically, after the Rubik's cube robot drives the motor 33 to rotate, the driving teeth in the motor 33 drive the second gear set 35, the second gear set 35 drives the first gear set 34, and the rotating shaft 31 arranged in the first gear set 34 rotates, thereby driving the magnet 41 and the transmission tooth 36 to rotate, and the Rubik's cube matching claw 32 and the magnetic positioning function are operated. In a preferred embodiment, the first gear set 34 and the second gear set 35 are both composed of a plurality of gear elements. By setting a plurality of gears for transmission, the torque can be increased and the rotation speed can be reduced, thereby ensuring the stability of the rotation of the Rubik's cube matching claw 32. In a preferred embodiment, the first gear set is composed of two first gear units, and the second gear set is composed of two second gear units.

[0059] In a possible implementation, the Rubik's Cube matching claw 32 of the above-mentioned portable magnetic positioning Rubik's Cube robot includes a column 320 and a connecting seat 321 connected to the column 320. The column 320 is transmission-connected to the rotating shaft 31, and the connecting seat 321 is provided with a plug-in part 322 that matches the Rubik's Cube color block.

[0060] Specifically, see Figure 5, the connecting seat 321 has a certain extension length and is elastic, the plug-in portion 322 is arranged on the connecting seat 321, and when the plug-in portion 322 is plugged into the column hole of the Rubik's Cube color block, the elasticity of the connecting seat 321 enables the plug-in portion 322 and the column hole of the Rubik's Cube color block to fit tightly without looseness. In a preferred embodiment, the column 320, the connecting seat 321 and the plug-in portion 322 are an integrally formed part, the production process is simple, and no later installation is required, which saves production costs and time, and the integrally formed part has a firm structure, which extends the service life of the product. In a preferred embodiment, the outer periphery of the plug-in portion 322 is coated with a layer of silicone. Under this setting, the cooperation between the Rubik's Cube matching claw 32 and the Rubik's Cube color block will not slip, which can improve the stability of the Rubik's Cube robot, facilitate the execution of precise rotation movements, and enable the Rubik's Cube color block to rotate to a precise angle.

[0061] In a possible implementation, the movable arm 2 of the portable magnetic positioning Rubik's Cube robot further includes a lower shell 20, an upper shell 21 and an inner shell 22, wherein the lower shell 20 is snapped together with the upper shell 21, and a chamber for placing the inner shell 22 is formed between the lower shell 20 and the upper shell 21, wherein the inner shell 22 is used to accommodate the rotating mechanism 3, and a flange 220 is provided on the top of the inner shell 22, and a rotating seat 221 is provided in the flange 220, wherein the magnet 41 is rotatably accommodated on the rotating seat 221, and the magnetic positioning component 4 is covered on the flange 220.

[0062] The structure of the movable arm 2 is arranged by buckling the lower shell 20 and the upper shell 21. When assembling the movable arm 2, the inner shell 22 is installed on the lower shell 20. The lower shell 20 and the upper shell 21 can be fixed by male and female buckles or bolts.

[0063] In actual application, when the motor 33 rotates, it drives the gear set to rotate, and the gear assembly drives the transmission teeth 36 and the rotating shaft 31 to rotate together. The radial magnet is tightly mounted on the rotating shaft 31, so the magnet 41 and the rotating shaft 31 have the same rotation angle. During the operation of the magic cube machine, the Hall angle sensor 420 arranged opposite to the magnet 41 detects the change in the magnetic pole direction of the radial magnet. The magnetic pole direction change information is processed by the information processing unit to measure the rotation angle of the gear assembly, and the data is fed back to the magic cube robot or terminal for calculation, and then the rotating mechanism 3 is controlled according to the preset program, so as to ensure the consistency of the rotation angle of the rotating mechanism 3 and avoid the abnormal displacement of the magic cube color block. The utility model adopts a method of multiple gears meshing with each other to realize the transmission of the rotating mechanism 3. The multiple gears cooperate with each other to transmit, which can increase the torque of the motor 33, reduce the speed of the motor 33, improve the control of the magic cube robot over the motor 33, and facilitate fine-tuning of the rotating shaft 31 to realize the function of angle correction.

[0064] In one possible implementation, see Figure 6 and Figure 7 , and combined with Figure 1 The machine 1 of the portable magnetic positioning Rubik's Cube robot includes a base 11 and a driving seat 12, wherein the driving seat 12 is located on the top of the base 11, a first through hole 110 is opened on the driving seat 12, and a second through hole 120 is opened on the base 11. The plurality of movable arms 2 are arranged around the outer peripheral surface of the driving seat 12 and are rotatably connected to the driving seat 12.

[0065] In a possible implementation, the Rubik's Cube robot further includes an infrared sensor 5, which is disposed on the driving seat 12. The probe of the infrared sensor 5 can irradiate outward through the first through hole 110, and the infrared sensor 5 is used to collect distance information between the Rubik's Cube and the driving seat 12. In this embodiment, the infrared sensor 5 is disposed on the Rubik's Cube robot. When the user puts the Rubik's Cube into the space, the probe of the infrared sensor 5 irradiates infrared light outward when the power is turned on, and calculates whether the current distance between the Rubik's Cube and the driving seat 12 is a preset value, so as to avoid the Rubik's Cube from running the rotating mechanism 3 when it is not aligned, resulting in an operation error of the Rubik's Cube robot. By introducing the infrared sensor 5 to monitor the installation of the Rubik's Cube, the user experience can be improved.

[0066] In one possible implementation, see Figure 6 and Figure 7 , and combined with Figure 1 The above-mentioned Rubik's Cube robot also includes a light guide ring 6 and a light guide button 7. The top of the driving seat 12 is provided with a groove 121 for the light guide ring 6 to be embedded. The light guide button 7 is arranged in the base 11, and the control end of the light guide button 7 is exposed in the second through hole 120. The light guide button 7 is communicatively connected with the light guide ring 6.

[0067] Specifically, when the Rubik's Cube is loaded into the workspace, the light guide button 7 can be activated, the Rubik's Cube robot controls the light guide ring 6 to start, and the color sensor provided inside the Rubik's Cube robot respectively collects the colors of an edge block and a corner block in the bottom color block of the Rubik's Cube, so that the corresponding control logic can be selected according to the current color of the color block to rotate the rotating mechanism 3. In a preferred embodiment, the color sensor includes a color sensing module, and when the color sensing module collects the color, the light guide ring 6 performs fill light, so as to facilitate the color sensing module to collect the correct color of the Rubik's Cube color block.

[0068] Compared with the prior art, the portable magnetic positioning Rubik's Cube robot provided by the utility model can improve the rotation accuracy of the rotating mechanism 3 by arranging a magnet 41 on the rotating mechanism 3 and using a magnetic positioning element 42 to monitor the change of the magnetic pole direction of the magnet 41, which is beneficial for the Rubik's Cube robot to stably perform the rotation action, and improves the reliability and portability of the Rubik's Cube robot's operation.
