Description

Technical Field

[0001] This disclosure relates to the field of gyroscope toy technology, and more particularly to a ratchet-type split-shell gyroscope structure. Background Technology

[0002] As a handheld entertainment toy with stress-relieving functions, a fidget spinner consists of a bidirectional or multidirectional symmetrical body as its main body, with a ball bearing embedded in the center, forming a planar rotating object. It is rotated by grasping and flicking with a few fingers; the rapid rotation of the ball bearing causes the symmetrical body of the spinner to spin rapidly as well. This provides visual feedback and a tactile vibration, achieving the purpose of stress relief. Existing fidget spinners are usually symmetrical bodies with cool designs, essentially improvements to the product's appearance. Their limited functional structure results in a monotonous gameplay experience limited to flicking to produce rapid rotation, failing to meet diverse consumer needs. Therefore, this solution aims to optimize and improve existing fidget spinner toys. Utility Model Content

[0003] In view of this, this technical solution proposes a ratchet-operated open-armor gyroscope structure. The ratchet structure is designed to include two rotation modes: one is the rapid rotation of a normal bearing, during which the side armor will be inertially thrown out and open; the other is the unidirectional rotation of the ratchet, during which the collision of the ratchet teeth produces an impact sound.

[0004] According to one aspect of this disclosure, a ratchet-type open-shell gyroscope structure is provided, including a gyroscope body, a ball bearing, a bottom cap, and a top cap. The gyroscope body has a mounting cavity at its center, and the ball bearing is embedded in the mounting cavity. The bottom of the mounting cavity has a through hole, and the bottom cap is installed at the through hole. The bottom cap has a first internally threaded connecting post protruding upwards at its center, and the top cap has a second internally threaded connecting post protruding downwards at its center. The first and second internally threaded connecting posts are connected by a screw. The outer wall of the first internally threaded connecting post is tightly fitted to the inner ring of the ball bearing. A first ratchet disc is sleeved around the periphery of the mounting cavity, and a second ratchet disc is sleeved around the periphery of the second internally threaded connecting post. An elastic component is provided between the back of the second ratchet disc and the bottom of the top cap. Both the first and second ratchet discs are annular structures. The second ratchet disc abuts against the second ratchet disc elastically, and the contact surfaces are provided with meshing ratchet teeth. A first connector is provided at the bottom of the second ratchet disc, and a second connector is provided at the top of the top cap. The first and second connectors are used to adjust the tightness of the second ratchet disc. The gyroscope body has at least one pair of symmetrical side bodies along the mounting cavity. Each symmetrical side body has a side cavity with an opening facing outwards. A side wing armor is provided in the side cavity, and the side wing armor is connected to the rotating shaft of the side cavity.

[0005] In one preferred embodiment, the first connector includes an annular portion, with an externally threaded connecting portion extending upward symmetrically along the inner annular hole wall of the annular portion. The ratchet teeth of the second ratchet disc have a stepped hole on their inner side, and the annular portion enters from the bottom of the stepped hole and hooks into the stepped hole. The top of the top cap has an annular groove along the periphery of the second internally threaded connecting post, and the bottom of the annular groove has a corresponding hole through which the externally threaded connecting portion passes. The second connector is an internally threaded annular component, which is threadedly connected to the externally threaded connecting portion, and the top surface of the internally threaded annular component has a screwing structure for screwing the internally threaded annular component.

[0006] Furthermore, the screwing structure adopts a screwing handle set on the top of the internal threaded annular part, or adopts a notch provided at a symmetrical position on the top of the internal threaded annular part, the notch being used for screwing the second connector with fingers or tools.

[0007] Preferably, the outer wall of the internally threaded annular component is provided with a first annular groove, and an O-ring is fitted inside the first annular groove. The O-ring and the inner wall of the annular groove form a damping effect.

[0008] Preferably, the elastic component is a compression spring or a spring sheet, and at least two compression springs or spring sheets are respectively disposed at symmetrical positions on the top surface of the second ratchet disc.

[0009] Furthermore, the top cap is shaped like a frustum of a cone with a top outer diameter smaller than the bottom outer diameter. The upper and lower surfaces of the symmetrical sides of the gyroscope body and the upper and lower surfaces of the side wing armor are provided with grooves, which are used for decoration or for installing fluorescent strips.

[0010] Furthermore, the sidewall of the mounting cavity protrudes upward at the center of the gyroscope body, and the outer periphery of the sidewall of the mounting cavity forms a ratchet mounting cavity for mounting the first ratchet disc with the gyroscope body. The outer side of the first ratchet disc is provided with a limiting protrusion protruding outward, and a limiting groove is provided corresponding to the ratchet mounting cavity for inserting the limiting protrusion.

[0011] Furthermore, a second annular groove is provided on the inner side wall of the top cavity of the mounting cavity, and a retaining spring is provided in the second annular groove for locking the ball bearing.

[0012] In one embodiment, the gyroscope body has a pair of symmetrical side bodies. One of the symmetrical side bodies has a shaft connection hole on the upper side of its side cavity, and the other symmetrical side body has a shaft connection hole on the lower side of its side cavity. The rotating shaft has a smooth rod at the upper end and an externally threaded connection at the lower end. The side wing armor has a screw hole corresponding to the externally threaded connection, and the smooth rod of the rotating shaft is rotatably connected to the shaft connection hole.

[0013] Furthermore, a first magnet is embedded on the inner side of the end of the side wing armor with a screw hole, and a second magnet that is magnetically attracted to the first magnet is embedded on the inner wall of the side cavity. When the gyroscope body rotates, the side wing armor opens outward with the rotational inertia around the axis of rotation. When the gyroscope body rotates in the opposite direction, the side wing armor retracts towards the side cavity with the rotational inertia, and the inner side of the side wing armor away from the screw hole strikes the inner wall of the side cavity, producing an impact sound.

[0014] The ratchet-driven open-shell gyroscope structure disclosed in this technical solution has the following advantages: The core innovative design of this gyroscope structure lies in the ingenious design of a ratchet disk structure, which includes a first ratchet disk and a second ratchet disk with meshing upper and lower ratchet teeth, and can adjust the tension or loosening of the second ratchet disk and the top cap. An elastic component is designed between the second ratchet disk and the top cap. In the untensioned and untensioned state of the second ratchet disk, the upper and lower elastic force provided by the elastic component causes the ratchet teeth of the second and first ratchet disks to mesh with each other, but can rotate circumferentially. When rotating, the ratchet teeth of the first ratchet disk rotate relative to the ratchet teeth of the second ratchet disk. Due to the upper and lower elastic force provided by the elastic component, the ratchet teeth of the first and second ratchet disks collide and produce a "click-click-click" sound when rotating. When the first and second connectors on the top cap pull the second ratchet towards the top of the top cap, the ratchet teeth of the second ratchet completely separate from those of the first ratchet. This allows the gyroscope to rotate rapidly along the ball bearings when the main body is rotated. This design provides two usage modes for this solution, increasing the ways consumers can play with the gyroscope. Simultaneously, side armor is designed into the symmetrical sides of the gyroscope's main body. During high-speed rotation, the side armor can be "thrown out" ("opening the armor") by rotational inertia, and "closed" ("closing the armor") by inertia during high-speed rotation in the opposite direction, enhancing the user experience.

[0023] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this disclosure.

[0024] Please refer to Figures 1 to 8 This is a specific embodiment of a ratchet-driven split-shell gyroscope structure disclosed in this technical solution. In this embodiment, it includes a gyroscope body 1, a ball bearing 2, a bottom cap 3, and a top cap 4. The gyroscope body 1 has a mounting cavity 101 at its center, and the ball bearing 2 is embedded in the mounting cavity 101. The bottom of the mounting cavity 101 has a through hole, and the bottom cap 3 is installed at the through hole. The bottom cap 3 has a first internally threaded connecting post protruding upward at its center, and the top cap 4 has a second internally threaded connecting post protruding downward at its center. The first internally threaded connecting post and the second internally threaded connecting post are connected by a screw. The outer wall of the first internally threaded connecting post is tightly fitted to the inner ring of the ball bearing 2. A first ratchet disc 7 is sleeved around the mounting cavity 101, and the second internally threaded connecting post... A second ratchet disc 8 is fitted around the outer edge, and an elastic component is provided between the back of the second ratchet disc 8 and the bottom of the top cap 4; both the first ratchet disc 7 and the second ratchet disc 8 are annular structures, and the second ratchet disc 8 is elastically abutted against the second ratchet disc 8, with meshing ratchet teeth on the contact surface; a first connector 9 is provided at the bottom of the second ratchet disc 8, and a second connector 10 is provided at the top of the top cap 4, the first connector 9 and the second connector 10 are used to adjust the tightness of the second ratchet disc 8; the gyroscope body 1 is provided with at least a pair of symmetrical side bodies along the mounting cavity 101, and each symmetrical side body is provided with a side cavity 102 with an opening facing outward, and a side wing armor 12 is provided in the side cavity 102, the side wing armor 12 being connected to the rotating shaft 1201 of the side cavity 102.

[0025] Please refer to Figure 1The first connector 9 includes an annular portion 901, and an externally threaded connecting portion 902 extends upward symmetrically along the inner annular hole wall of the annular portion 901. The ratchet tooth of the second ratchet disc 8 is provided with a stepped hole, and the annular portion 901 enters from the bottom of the stepped hole and hooks into the stepped hole. The top of the top cap 4 is provided with an annular groove along the periphery of the second internally threaded connecting post, and the bottom of the annular groove is provided with a hole corresponding to the externally threaded connecting portion 902. The second connector 10 is an internally threaded annular component 1001, which is threadedly connected to the externally threaded connecting portion 902. The top surface of the internally threaded annular component 1001 is provided with a screwing structure for screwing the internally threaded annular component 1001.

[0026] Please refer to Figure 3 , Figure 4 , Figures 6 to 8 The ratchet-driven gyroscope structure disclosed in this embodiment includes two modes of play. One mode is the ratchet mode, where the first connecting member 9 and the second connecting member 10 are not tightened. The ratchet teeth of the first ratchet disc 7 and the second ratchet disc 8 are abutted by the elastic component. When rotating, the gear of the first ratchet disc 7 can push the second ratchet disc 8 upward, while the second ratchet disc 8 is pushed downward by the elastic component. When the first ratchet disc 7 and the second ratchet disc 8 rotate circumferentially, the ratchet teeth emit a "click-click-click" impact sound, thus providing the user with impact sound and impact vibration feedback. This auditory and tactile feedback can relieve pressure. Another type is the non-ratchet mode, which is also the traditional fidget spinner mode. The second connector 10 is screwed on to tighten the first connector 9. As the first connector 9 rises, it pulls the second ratchet disk 8 upward, thus completely separating it from the ratchet teeth of the first ratchet disk 7. When the fingers pinch the top cap 4 and the bottom cap 3, the spinner body 1 is quickly spun. The spinner body 1 can rotate rapidly under the rotation of the ball bearing 2. Due to the high rotation speed, the side armor 12 can be thrown out of the open armor, or when it is rotated in the opposite direction, the already opened side armor 12 can be thrown into the side cavity 102.

[0027] As a preferred embodiment, the screwing structure adopts a screwing handle set on the top of the internal threaded annular part 1001, or adopts a notch 1002 provided at a symmetrical position on the top of the internal threaded annular part 1001, the notch 1002 being used for screwing the second connector 10 with fingers or tools.

[0028] As a preferred embodiment, the outer wall of the internally threaded annular component 1001 is provided with a first annular groove, and an O-ring 1003 is sleeved in the first annular groove. The O-ring 1003 and the inner wall of the annular groove form a damping effect.

[0029] As a preferred embodiment, the elastic component is a compression spring 11 or a spring sheet, and at least two compression springs 11 or spring sheets are respectively disposed at symmetrical positions on the top surface of the second ratchet disk 8.

[0030] As a preferred embodiment, the top cap 4 is shaped like a frustum of a cone with a top outer diameter smaller than the bottom outer diameter. The frustum-shaped top cap 4, together with the overall shape of the gyroscope body 1, forms a cool "flying saucer"-like design. The upper and lower surfaces of the symmetrical sides of the gyroscope body 1 and the upper and lower surfaces of the side wing armor 12 are provided with grooves, which are used for decoration or for installing fluorescent strips.

[0031] Furthermore, the sidewall of the mounting cavity 101 protrudes upward at the center of the gyroscope body 1, and the outer periphery of the sidewall of the mounting cavity 101 forms a ratchet mounting cavity 105 for mounting the first ratchet disk 7 with the gyroscope body 1. The outer side of the first ratchet disk 7 is provided with a limiting protrusion 701 protruding outward, and a limiting groove 106 is provided corresponding to the ratchet mounting cavity 105 for inserting the limiting protrusion 701.

[0032] As a preferred embodiment, the inner side wall of the top cavity of the mounting cavity 101 is provided with a second annular groove, and a retaining spring 13 is provided in the second annular groove for locking the ball bearing 2.

[0033] In this embodiment, as an example, the gyroscope body 1 is provided with a pair of symmetrical side bodies. The upper side of the side cavity 102 of one symmetrical side body is provided with a shaft connection hole 103, and the lower side of the side cavity 102 of the other symmetrical side body is provided with a shaft connection hole 103. The rotating shaft 1201 has a smooth rod part at the upper end and an external threaded connection part 902 at the lower end. The side wing armor 12 is provided with a screw hole position that is threaded to the external threaded connection part 902. The smooth rod part of the rotating shaft 1201 is rotatably connected to the shaft connection hole 103.

[0034] As a preferred embodiment, a first magnet 14 is embedded on the inner side of the end of the side wing armor 12 with screw holes, and a second magnet 15, which is magnetically attracted to the first magnet 14, is embedded on the inner wall of the side cavity 102. When the gyroscope body 1 rotates, the side wing armor 12 opens outward with the rotational inertia around the axis of rotation. When the gyroscope body 1 rotates in the opposite direction, the side wing armor 12 retracts into the side cavity 102 with the rotational inertia, and the inner side of the side wing armor 12 away from the screw holes strikes the inner wall of the side cavity 102, producing an impact sound. When the side wing armor 12 retracts into the side cavity 102, the magnetic attraction helps prevent the side wing armor 12 from opening arbitrarily within the side cavity 102. The magnetic attraction has an inertial force of attraction, which can provide a better tactile experience when using the product.

[0035] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
