Description

Technical Field

[0001] The utility model relates to the field of Rubik's cube toys, in particular to a Rubik's cube center block and a Rubik's cube. Background Art

[0002] The traditional three-stage Rubik's Cube is a cube made of elastic hard plastic. The core of the Rubik's Cube is an axis and consists of 26 blocks, including 12 edge blocks, 8 corner blocks and 6 center blocks. Only one side of the center block has color, and the edge blocks and corner blocks can rotate. When the product is sold, the blocks are arranged so that each side of the Rubik's Cube has the same color. When one side of the Rubik's Cube rotates horizontally, the single color of the adjacent sides is destroyed, and a new pattern of cubes is formed. After turning and changing again, each side of the Rubik's Cube can eventually be made up of blocks of different colors. The way to play the Rubik's Cube is to restore the scrambled cube to a single color on all six sides as quickly as possible by rotating it.

[0003] Common Rubik's Cube structures such as Figure 1 As shown, the four corners of the Rubik's Cube center block respectively form four gaps with the Rubik's Cube corner blocks, edge blocks, etc. The four gaps are distributed in a circular array. In order to form these gaps, the four corners of the Rubik's Cube center block are usually designed to be similar to rounded corners or chamfered shapes. The outer shell of the Rubik's Cube center block usually includes two parts: the center block bottom shell and the center block top cover. The bottom shell has four corner side walls, and the corner side walls are designed to be similar to rounded corners or chamfered shapes. Similarly, the four corners of the top cover are also designed to be similar to rounded corners or chamfered shapes. The gaps in the four corners of the Rubik's Cube center block have an important function, which is to provide users with a certain amount of space to facilitate the disassembly of the Rubik's Cube center block top cover.

[0004] The inside of the Rubik's Cube center block will be equipped with a magnetic dial, an elastic dial or a wheelbase dial, etc., so that the user can adjust the magnetic force, elastic force or wheelbase of the Rubik's Cube center block. Obviously, the top cover of the Rubik's Cube center block needs to be removed before adjustment.

[0005] The existing Rubik's Cube center block mainly relies on friction to achieve assembly and fixation between the bottom shell and the top cover. However, in many cases, in order to facilitate the removal of the top cover, the fit between the top cover and the bottom shell is not very tight, and the fit between the two is prone to be too loose. As a result, the top cover of the center block is prone to fall off during the rotation of the Rubik's Cube, which is very unfriendly to the experience of professional players who pursue speed.

[0037] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0038] refer to Figure 1-Figure 7 The embodiment of the utility model provides a Rubik's Cube center block 1 and a Rubik's Cube 2. Figure 1 The appearance structure of the magic cube 2 is as follows Figure 1 As shown, in the Rubik's Cube 2, four gaps 3 are formed in the directions of the four corner ends of the Rubik's Cube center block 1, and these gaps 3 can facilitate the disassembly of the top cover of the Rubik's Cube center block 1.

[0039] refer to Figure 2-Figure 7 The magic cube center block 1 of the embodiment of the utility model comprises a bottom shell 100 and a top cover 200. The bottom shell 100 and the top cover 200 can be made of elastic hard plastic.

[0040] The bottom shell 100 of the Rubik's Cube center block 1 includes a center block bottom wall 101 and a center block side wall 102 fixedly connected to the center block bottom wall 101. The center block side wall 102 includes four corner end side walls 103. These corner end side walls 103 are provided with snap holes 104, and the snap holes 104 penetrate the inner and outer sides of the bottom shell 100.

[0041] The top cover 200 of the center block 1 of the Rubik's Cube includes a center block top wall 201 and four elastic rods 202 corresponding to the four corner side walls 103, and the top ends of the elastic rods 202 are fixed to the bottom surface of the center block top wall 201. The corner side walls 103 correspond to the elastic rods 202, which means that when the bottom shell 100 and the top cover 200 are assembled and fixed together, the positions of the corner side walls 103 correspond to the positions of the elastic rods 202.

[0042] When the bottom shell 100 and the top cover 200 are assembled and fixed together, the elastic rod 202 is located on the inner side of the corner end side wall 103; in addition, the elastic rod 202 is fixed with a snap block 203, and the snap block 203 is snapped into the snap hole 104; the bottom shell 100 and the top cover 200 are assembled and fixed in a snap-fit ​​manner through the snap hole 104 and the snap block 203, and the top end of the hole wall of the snap hole 104 (i.e., a part of the corner end side wall 103) can snap the snap block 203, thereby effectively preventing the top cover 200 from detaching from the bottom shell 100.

[0043] The Rubik's Cube center block 1 of the embodiment of the present invention is assembled and fixed with its bottom shell 100 and top cover 200 by the above-mentioned snap-fit ​​method, which can effectively prevent the top cover from falling off during the rotation of the Rubik's Cube, and helps to improve the player experience.

[0044] In the Rubik's Cube center block 1 of the embodiment of the utility model, the buckle hole 104 is located at the bottom of the corner end side wall 103, and the elastic rod 202 is fixed with a force-bearing boss 204, which is buckled into the buckle hole 104. The force-bearing boss 204 and the buckle block 203 are part of the elastic rod 202, and are exposed through the buckle hole 104 to facilitate the disassembly of the top cover 200. In addition, the buckle hole 104 is located at the bottom of the corner end side wall 103, so that the buckle structure of the Rubik's Cube center block 1 can be well hidden visually (the buckle hole 104, the buckle block 203 and other structures are located at a relatively deep position in the gap 3), and do not affect the appearance of the Rubik's Cube.

[0045] In the Rubik's Cube center block 1 of the embodiment of the utility model, the buckle block 203 and the force-bearing boss 204 are both located on the side of the elastic rod 202 facing the buckle hole 104, and the buckle block 203 is located at the top of the force-bearing boss 204; the side of the elastic rod 202 facing away from the buckle hole 104 is provided with a reinforcing rib 205. By providing the force-bearing boss 204, the disassembly tool can more easily squeeze the elastic rod 202, which facilitates the disassembly of the top cover.

[0046] In the Rubik's Cube center block 1 of the embodiment of the present invention, the four corner side walls 103 of the bottom shell 100 are distributed in a circular array, and the center block side wall 102 of the bottom shell 100 also includes four main side walls 105; these four main side walls 105 and the four corner side walls 103 are arranged in a staggered manner, and together constitute the center block side wall 102.

[0047] The four elastic rods 202 of the top cover 200 are distributed in a circular array, and the orientations of the four elastic rods 202 correspond to the four corners of the center block top wall 201. The four corner side walls 103 of the bottom shell 100 are chamfered or rounded, and the four corners of the center block top wall 201 are chamfered or rounded. Figure 1 The design of these chamfered or rounded structures helps to form gaps 3 at the four corner ends of the Rubik's Cube center block 1. These gaps 3 have an important function, which is to provide users with a certain space to facilitate the disassembly of the top cover 200.

[0048] In the Rubik's Cube center block 1 of the embodiment of the present invention, the top cover 200 also includes four connecting plates 206, which are fixed to the bottom surface of the top wall 201 of the center block and are arranged in a staggered manner with the four elastic rods 202 of the top cover 200; the bottom surface of the top wall 201 of the center block has an edge area 207 on the outside direction of the connecting plates 206 and the elastic rods 202; when the bottom shell 100 and the top cover 200 are assembled and fixed together, the edge area 207 overlaps with the top surface of the side wall 102 of the center block.

[0049] In the Rubik's Cube center block 1 of the embodiment of the present invention, a first transition slope 208 is provided on the lower side of the top cover 200, and the first transition slope 208 gradually descends toward the direction of the force-bearing boss 204; a second transition slope 209 is provided on the lower side of the force-bearing boss 204, and the second transition slope 209 gradually descends toward the direction of the elastic rod 202. The first transition slope 208 and the second transition slope 209 are provided to facilitate the installation of the top cover 200 on the bottom shell 100 by buckling; and because the positions of the elastic rod 202, the corner end side wall 103, the buckle hole 104, etc. all correspond to the four corner ends of the Rubik's Cube center block 1, when installing the top cover 200, the four corner ends of the top cover 200 are aligned with the four corner ends of the bottom shell 100 (or the center block side wall 102), and then the top cover 200 is buckled into the bottom shell 100 until the buckle block 203 is buckled into the buckle hole 104, thus completing the assembly and fixation of the outer shell of the Rubik's Cube center block 1.

[0050] In the Rubik's Cube center block 1 of the embodiment of the present invention, the four corner ends of the center block top wall 201 are provided with guide slopes 210, which are located on the top surface of the center block top wall 201 and gradually descend toward the periphery of the center block top wall 201.

[0051] by Figure 8 and Fig. 9 Taking the disassembly tool shown as an example, how to disassemble the top cover of the Rubik's Cube center block 1 of the embodiment of the utility model is explained. The disassembly tool includes a positioning seat, a pressing key and a reset spring. Four positioning tracks are fixed at the bottom end of the positioning seat. The pressing key is slidably assembled on the inner side of the positioning seat and can move up and down relative to the positioning seat. Four disassembly claws are fixed at the bottom end of the pressing key. The four disassembly claws correspond to the four positioning tracks of the positioning seat respectively.

[0052] Taking the above disassembly tool as an example, the disassembly process of the top cover 200 of the Rubik's Cube center block 1 of the embodiment of the utility model is as follows:

[0053] 1)Reference Fig.10 and Fig.11 First, the positioning seat of the disassembly tool needs to be placed on the surface of the Rubik's Cube 2, wherein the four positioning rails of the positioning seat need to be lowered to the gaps 3 in the four corners of the Rubik's Cube center block 1 respectively. After the positioning is completed (i.e., after the positioning seat is placed), the position of the bottom end of the positioning rail corresponds to the position of the buckle hole 104 of the bottom shell 100;

[0054] 2)Reference Fig.12 After the positioning is completed, the push button of the disassembly tool is pressed downward. At this time, the four disassembly claws of the push button move downward along the four positioning tracks of the positioning seat respectively. The bottom ends of the disassembly claws will be squeezed by the bottom ends of the positioning tracks, and then move along the extension direction of the bottom ends of the positioning tracks. At this time, the bottom ends of the disassembly claws squeeze the elastic rods 202 through the buckle holes 104 of the bottom shell 100, causing the top cover 200 to be deformed into an arch shape and then bounce up. Then, the disassembly tool and the top cover 200 can be taken out.

[0055] 3) After the top cover 200 of the Rubik's Cube center block 1 pops up, release the push button of the disassembly tool. Under the action of the reset spring, the push button rebounds. At this time, the disassembly tool is taken out from the Rubik's Cube 2, and the top cover 200 is separated from the bottom shell 100 along with the disassembly tool. Then, press the push button of the disassembly tool again to remove the top cover 200. At this point, the disassembly and removal of the top cover 200 is completed.

[0056] During the disassembly process of the top cover 200, the guide slope 210 on the top cover 200 can cause the disassembly claw to descend along the guide slope 210 when the push button of the disassembly tool is pressed, thereby facilitating the disassembly work; the edge area 207 of the top cover 200 can be hooked by the disassembly claw when the button is pressed to reset after the top cover 200 pops up, and then the disassembly claw drives the top cover 200 to separate from the bottom shell 100.

[0057] refer to Fig.13 , which shows another embodiment of the Rubik's Cube center block 1. Fig.13The center block shown is Figure 2 The main differences of the center blocks shown are: Fig.13 In the center block, four corners of the bottom wall 101 of the center block are respectively formed with four convex corners 106, and the convex corners 106 protrude toward the outer side of the corner end side wall 103. The arrangement of the convex corners 106 helps to prevent the center block from rotating at high speed and causing restoration errors due to self-rotation.

[0058] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
