Description

Technical Field

[0001] The present invention relates to the technical field of educational toys, and in particular to a three-dimensional smart ring and an unlocking method and a locking method thereof. Background Art

[0002] Educational toys are toys that develop intelligence and increase wisdom during play. For example, unlocking educational toys contain multiple parts. In the unlocked state, all parts are separated and independent of each other. In the locked state, all parts are assembled together to form an inseparable whole. Users need to have good logical thinking ability and hand-eye coordination ability to complete the unlocking, and experience a sense of accomplishment after successfully unlocking. Although there are many types of educational toys on the market, their shapes are relatively monotonous, lacking novelty, and it is difficult to stimulate users' interest in unlocking.

[0003] Therefore, how to design unlocking educational toys with novel shapes and high fun is a technical problem that the industry needs to solve urgently. Summary of the invention

[0004] In order to solve the deficiencies in the prior art, the present invention proposes a three-dimensional smart ring and an unlocking method and a locking method thereof. The three-dimensional smart ring has a lock core and a lock ring. The two columns of the lock core are confined in the cross-shaped through hole of the lock ring. The posture of the lock core is adjusted by rotating to achieve unlocking and locking of the lock core and the lock ring. The three-dimensional smart ring has a novel shape and is more interesting.

[0005] The technical solution adopted by the present invention is to design a three-dimensional smart ring, including:

[0006] The lock core has three columns arranged crosswise at the midpoint, any two columns are perpendicular to each other, the main body of the column is a rectangular parallelepiped, and each column is provided with two protrusions located on different sides;

[0007] The lock ring has a cross-shaped through hole, and the two upright posts of the lock core are confined in the cross-shaped through hole. The hole wall of the cross-shaped through hole is provided with a groove group that allows the lock core to rotate. The groove group penetrates the front and back sides of the lock ring to form a plurality of notches, and among all the notches, only one unlocking notch allows the protrusion to escape from the lock ring;

[0008] With the plane perpendicular to the central axis of the cross-shaped through hole as the projection plane, the lock core can be rotated to an unlocking posture in which the projection plane is cross-shaped with only one protrusion, or to a locking posture in which the projection plane is cross-shaped with three protrusions;

[0009] When the lock core is in an unlocking posture and the protrusion is aligned with the unlocking notch in the axial direction of the lock ring, the lock core is pushed out of the lock ring to release the lock. When the lock core is in a locking posture and a protrusion is aligned with the unlocking notch in the axial direction of the lock ring, the lock core and the lock ring are completely locked.

[0010] Further, one end of the protruding portion is close to the center of the lock core, and the other end of the protruding portion arches towards the end of the column where it is located to form an arc-shaped end face. Both the front and back sides of the lock ring are provided with more than two limiting notches. The limiting notches allow the protruding portion to rotate through and prevent the protruding portion from disengaging from the lock ring.

[0011] Further, the side of the protruding portion away from the column where it is located arches outwards to form an arc-shaped side surface; when the protruding portion rotates through the limiting notch, the outermost side of the arc-shaped side surface is close to the limiting notch.

[0012] Further, each column is composed of a rectangular main body and spherical parts located at both ends of the main body. The centers of the spheres of all the spherical parts coincide as the center point of the lock core. The axes of the arc-shaped side surfaces and the axes of the arc-shaped end faces of the respective protruding portions all pass through the center point of the lock core.

[0013] In some embodiments, the three columns are respectively the first column, the second column, and the third column; the two protruding portions of the first column are respectively located on two opposite side surfaces, and one protruding portion is located at one end of the first column and the other protruding portion is located at the other end of the first column; the two protruding portions of the second column are respectively located on two adjacent side surfaces, and one protruding portion is located at one end of the second column and the other protruding portion is located at the other end of the second column; the two protruding portions of the third column are respectively located on two adjacent side surfaces, and the two protruding portions are located at the same end of the third column.

[0014] Further, notches are provided at all four intersections of the cross-shaped through hole; on the back side of the lock ring, an unlocking notch, a stepped limiting notch, a stepped limiting notch, and a first limiting notch are sequentially arranged in the clockwise direction. On the front side of the lock ring, a second limiting notch, a stepped limiting notch, a stepped limiting notch, and a first limiting notch are sequentially arranged in the clockwise direction; the length direction of the unlocking notch is parallel to the length direction of the first limiting notch, the length directions of the first limiting notch and the second limiting notch are perpendicular to each other, the stepped limiting notch is formed by connecting the first limiting notch and the second limiting notch, and the unlocking notch and the second limiting notch are aligned in the axial direction of the lock ring.

[0015] The present invention also proposes an unlocking method for the three-dimensional intelligent ring. This unlocking method is applied to the above-mentioned three-dimensional intelligent ring. When the lock core and the lock ring are completely locked, the unlocking method includes the following steps:

[0016] Taking the third column as the rotation axis, rotate the lock core towards the back side of the lock ring until the lock core can no longer rotate;

[0017] Taking the second column as the rotation axis, rotate the lock core towards the back side of the lock ring until the lock core can no longer rotate;

[0018] With the first upright post as the rotation axis, rotate the lock core towards the front of the lock ring until the lock core rotates to the unlocked position, and then push the lock core out of the lock ring along the axial direction of the lock ring to release the lock.

[0019] The present invention also proposes a locking method for the three-dimensional intelligent ring. This locking method is applied to the above-mentioned three-dimensional intelligent ring, where the lock core and the lock ring are separated from each other. The locking method includes the following steps:

[0020] Adjust the lock core to the unlocked position so that the protruding part is aligned with the unlocking notch, and then push the lock core into the cross-shaped through hole along the axial direction of the lock ring;

[0021] With the first upright post as the rotation axis, rotate the lock core towards the back of the lock ring until the lock core cannot rotate further;

[0022] With the second upright post as the rotation axis, rotate the lock core towards the back of the lock ring until the lock core cannot rotate further;

[0023] With the third upright post as the rotation axis, rotate the lock core towards the front of the lock ring until the lock core rotates to the locked position, and the lock core and the lock ring are completely locked.

[0024] Compared with the prior art, the lock core of the present invention has three upright posts perpendicular to each other, the lock ring has a cross-shaped through hole, and the lock ring has only one unlocking notch. The lock core can rotate to the unlocked position or the locked position in the cross-shaped through hole. By adjusting the position of the lock core in the cross-shaped through hole, the unlocking and locking of the lock core and the lock ring can be achieved. The design of the three-dimensional intelligent ring is unique, attracting users to explore the unlocking and locking solutions. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this patent and are not used to limit this patent.

[0037] As Figures 1 to 6 shown, the three-dimensional intelligent ring proposed by the present invention is composed of a lock core 1 and a lock ring 2. The lock core 1 has three upright columns 11 with midpoint intersections. The three upright columns 11 have the same size, and any two upright columns 11 are perpendicular to each other. The main body of the upright column 11 is in the shape of a cuboid. The lock ring 2 has a cross-shaped through hole 21, which is composed of two linear through holes intersecting at the center. The two linear through holes have the same size and are perpendicular to each other. The size of the cross-shaped through hole 21 just allows any two upright columns 11 to move axially through the lock ring 2. The axial direction of the lock ring 2 refers to the central axis direction of the cross-shaped through hole 21.

[0038] Each upright column 11 is provided with two protruding parts 111 on different sides. Since the protruding parts 111 protrude beyond the side surface of the upright column 11, any two upright columns 11 of the lock core 1 are restricted in the cross-shaped through hole 21. The hole wall of the cross-shaped through hole 21 is provided with a groove group allowing the lock core 1 to rotate. Taking the plane perpendicular to the central axis of the cross-shaped through hole 21 as the projection plane, the lock core 1 can rotate to an unlocking posture in which it is in a cross shape and has only one protruding part 111 in the projection plane, or rotate to a locking posture in which it is in a cross shape and has three protruding parts 111 in the projection plane. After the lock core 1 and the lock ring 2 are locked, the lock core 1 can rotate in the cross-shaped through hole 21, and it must rotate to the unlocking posture to have a chance to escape from the cross-shaped through hole 21.

[0039] Specifically, as Figures 7 to 10As shown, one end of the protruding part 111 is close to the center of the lock core 1, and the other end of the protruding part 111 arches towards the end of the column 11 where it is located to form an arc-shaped end face. The maximum length of the protruding part 111 along the length direction of the column 11 where it is located is L1, and the maximum thickness of the protruding part 111 protruding outwards from the side of the column 11 where it is located is H1. The groove group penetrates through the front and back of the lock ring 2 to form a number of notches. Only one of all the notches is an unlocking notch 211 that allows the protruding part 111 to escape from the lock ring. The unlocking notch 211 is provided on the front or back of the lock ring 2. The unlocking notch 211 is rectangular. The length of the unlocking notch 211 is slightly greater than L1, and the width of the unlocking notch 211 is slightly greater than H1. The design standard of the unlocking notch 211 is to allow the protruding part 111 to escape from the lock ring 2 along the axial direction of the lock ring 2. Both the front and back of the lock ring 2 are provided with more than two limiting notches. The limiting notches are rectangular. The first limiting notch 212_2 and the second limiting notch 212_3 in the following text both belong to the limiting notches. The length of the limiting notch is less than L1, and the width of the limiting notch is slightly greater than H1. The design standard of the limiting notch is to allow the protruding part 111 to rotate through and block the protruding part 111 from escaping from the lock ring 2 along the axial direction of the lock ring 2. In some embodiments of the present invention, in order to make the rotation of the lock core 1 smoother, the side of the protruding part 111 away from the column 11 where it is located arches outwards to form an arc-shaped side surface. When the protruding part 111 rotates through the limiting notch 212, the outermost side of the arc-shaped side surface is close to the limiting notch, and the width of the limiting notch and the thickness H1 of the protruding part are in clearance fit.

[0040] After the lock core 1 and the lock ring 2 are locked, the two columns 11 of the lock core 1 are restricted in the cross-shaped through hole 21. Rotate the lock core 1 to adjust its posture. When the lock core 1 is in the unlocking posture and the protruding part 111 is axially aligned with the unlocking notch in the lock ring 2, push the lock core 1 outwards along the axial direction of the lock ring 2 to unlock it. After the lock core 1 and the lock ring 2 are unlocked, adjust the lock core 1 to the unlocking posture so that the protruding part 111 is aligned with the unlocking notch 211. Push the lock core 1 into the cross-shaped through hole 21 along the axial direction of the lock ring 2. Rotate the lock core 1 to adjust its posture. When the lock core 1 is in the locking posture and one of the protruding parts 111 is axially aligned with the unlocking notch 211 in the lock ring 2, the lock core 1 and the lock ring 2 are completely locked.

[0041] It should be understood that since the lock core 1 can only be unlocked when it is in the unlocking posture and the protruding part 111 is axially aligned with the unlocking notch 211 in the lock ring 2, the lock core 1 is in the locked state when it does not reach this unlocking condition, that is, the lock core 1 cannot escape from the lock ring 2. The user can complete the unlocking of the lock core 1 and the lock ring 2 through rotational operation, or further deepen the sleeved relationship between the lock core 1 and the lock ring 2 to make the unlocking difficulty between the lock core 1 and the lock ring 2 reach the highest level, that is, the lock core 1 and the lock ring 2 are completely locked, and the user needs to perform complex rotational operations to complete the unlocking of the lock core 1 and the lock ring 2.

[0042] To make the matching relationship between the lock core 1 and the lock ring 2 closer, each column 11 is composed of a rectangular main body and spherical parts located at both ends of the main body. The centers of the spherical parts of all spherical parts coincide as the center point of the lock core 1. The axes of the arc-shaped sides and the axes of the arc-shaped end faces of each protruding part 111 pass through the center point of the lock core 1. The shape of the cross-shaped through hole 21 and the groove group is designed according to the outer shape of the lock core 1. After the lock core 1 and the lock ring 2 are locked, there is less vacancy between the lock core 1 and the cross-shaped through hole 21, and the three-dimensional intelligent ring looks complete and coordinated.

[0043] As Figures 7 to 10 shown, a detailed description is given with an application example of the present invention. The three columns 11 are respectively the first column 11_1, the second column 11_2 and the third column 11_3; the two protruding parts 111 of the first column 11_1 are respectively located on two opposite side faces, and one protruding part 111 is located at one end of the first column 11_1 and the other protruding part 111 is located at the other end of the first column 11_1; the two protruding parts 111 of the second column 11_2 are respectively located on two adjacent side faces, and one protruding part 111 is located at one end of the second column 11_2 and the other protruding part 111 is located at the other end of the second column 11_2; the two protruding parts 111 of the third column 11_3 are respectively located on two adjacent side faces, and the two protruding parts 111 are located at the same end of the third column 11_3. When the lock core 1 is in the unlocked position, the third column 11_3 is parallel to the central axis of the cross-shaped through hole 21. When the lock core 1 is in the locked position, the second column 11_2 is parallel to the central axis of the cross-shaped through hole 21.

[0044] Notches are provided at the four intersections of the cross-shaped through hole 21. The front and back surfaces of the lock ring 2 are both flat, and the front and back surfaces of the lock ring 2 are both perpendicular to the central axis of the cross-shaped through hole 21. The unlocking notch 211, the stepped limiting notch 212_1, the stepped limiting notch 212_1 and the first limiting notch 212_2 are successively arranged on the back surface of the lock ring 2 in the clockwise direction. The second limiting notch 212_3, the stepped limiting notch 212_1, the stepped limiting notch 212_1 and the first limiting notch 212_2 are successively arranged on the front surface of the lock ring 2 in the clockwise direction. The length direction of the unlocking notch 211 is parallel to the length direction of the first limiting notch 212_2. The length directions of the first limiting notch 212_2 and the second limiting notch 212_3 are perpendicular to each other. The stepped limiting notch 212_1 is formed by connecting the first limiting notch 212_2 and the second limiting notch 212_3. The unlocking notch 211 and the second limiting notch 212_3 are axially aligned on the lock ring 2.

[0045] As Figure 1 、 2 shown, based on this application example, the unlocking method of the three-dimensional intelligent ring includes the following steps:

[0046] The lock core 1 and the lock ring 2 are completely locked, that is, when the lock core 1 is in the unlocked position, the lock core 1 is rotated toward the opposite side of the lock ring 2 with the third column 11_3 as the rotation axis until the lock core 1 can no longer rotate;

[0047] With the second column 11_2 as the rotation axis, rotate the lock core toward the opposite side of the lock ring 2 until the lock core 1 can no longer rotate;

[0048] With the first column 11_1 as the rotation axis, the lock core is rotated toward the front of the lock ring 2 until the lock core 1 is rotated to an unlocking posture, and the lock core 1 is pushed out of the lock ring 2 along the axial direction of the lock ring 2 to release the lock.

[0049] like Figure 5 , 6 As shown, the present invention also proposes a locking method for a three-dimensional smart ring, which is applied to the above-mentioned three-dimensional smart ring, wherein the lock core 1 and the lock ring 2 are separated from each other, and the locking method comprises the following steps:

[0050] Adjust the lock core 1 to the unlocking position, align the protrusion 111 with the unlocking notch 211, and push the lock core 1 into the cross-shaped through hole 21 along the axial direction of the lock ring 2;

[0051] With the first column 11_1 as the rotation axis, rotate the lock core 1 toward the opposite side of the lock ring 2 until the lock core 1 can no longer rotate;

[0052] With the second column 11_2 as the rotation axis, rotate the lock core 1 toward the opposite side of the lock ring 2 until the lock core 1 can no longer rotate;

[0053] With the third column 11_3 as the rotation axis, the lock core 1 is rotated toward the front of the lock ring 2 until the lock core 1 is rotated to a locked position, and the lock core 1 and the lock ring 2 are completely locked.

[0054] It can be seen from the above unlocking process or locking process that the rotation direction of the corresponding steps of the unlocking process is opposite to that of the locking process. The three-dimensional smart ring changes its state from unlocking to completely locked, and the degree of locking changes according to the progress of the unlocking action. The three-dimensional smart ring has a unique design, which attracts users to explore unlocking and locking solutions.
