Description

Technical Field

[0001] The present invention relates to the field of toys, in particular to a spinning top. Background Art

[0002] As a competitive and entertaining toy, spinning tops are popular among children for their diverse gameplay. The basic gameplay of existing toy spinning tops is to launch them onto a flat surface using a gyro launcher, which then spins them, or to install a motor inside the top to drive the spin. Further gameplay involves two players spinning and attacking each other, creating a competitive atmosphere and enhancing the fun. The key to victory in a competition lies in the top's speed, its stability, and the angle of attack.

[0003] However, the existing spinning tops generally have only one top, and during use, their running track is relatively simple and less interesting, which can no longer meet the requirements of current children in games or competitions. Moreover, since the top is fixedly mounted on the spindle seat or on the central axis body in the spindle seat, the extended length and shape of the top are fixed during the rotation on the plane or when the top rotates and attacks each other, and the running track is simple. Therefore, when the spinning top is hit, the stability is poor and the attack force is not strong, which reduces the interest of consumers in playing. Summary of the Invention

[0004] The object of the present invention is to provide a gyroscope to solve the technical problems in the prior art of a single running track of the gyroscope tip and poor impact stability.

[0005] As conceived above, the technical solution adopted by the present invention is:

[0006] A gyroscope comprises a central shaft that can slide along an axial hole and is configured to switch from a freely rotatable first gyroscope tip to a second gyroscope tip, and a rod that slidably cooperates with the central shaft; the lower end of the central shaft is the first gyroscope tip, and the outer edge of the lower end of the axial hole is the second gyroscope tip; in the absence of external force, the gyroscope rotates with the first gyroscope tip or the second gyroscope tip; when an external force strikes the first end of the rod, the rod pushes the central shaft to slide in a first direction, causing the first gyroscope tip to retract into the axial hole, thereby rotating the gyroscope with the second gyroscope tip; when an external force strikes the second end of the rod, the rod pushes the central shaft to slide in a direction opposite to the first direction, causing the first gyroscope tip to extend out of the axial hole, thereby rotating the gyroscope with the first gyroscope tip.

[0007] The extending direction of the shaft hole coincides with the first direction, and the rod can slide along the second direction under the action of an external force, and the first direction is perpendicular to the second direction.

[0008] The gyroscope further comprises a fixed surface cover and a bottom cover, the central axis is arranged at the center of the surface cover and the shaft sleeve, and the rod is arranged between the surface cover and the bottom cover.

[0009] Wherein, a shaft sleeve is detachably provided at the center of the bottom cover, and the shaft hole is opened on the shaft sleeve.

[0010] In which, a accommodating cavity is opened in the middle of the rod, and a limiting surface is set in the accommodating cavity. The limiting surface includes a first plane and a second plane arranged in a step with the first plane, and the first plane and the second plane are smoothly transitioned by an inclined surface; a protrusion is provided on the central axis, and the end face of the protrusion abuts and cooperates with the limiting surface.

[0011] Wherein, the lower end surface of the protrusion is in abutment with the limiting surface, and a first spring is provided between the protrusion and the surface cover.

[0012] Wherein, the upper end surface of the protrusion is in abutment with the limiting surface, and a second spring is provided between the protrusion and the shaft sleeve.

[0013] Wherein, at least one end of the rod is exposed from the outer surface of the gyroscope.

[0014] Wherein, the first tip is a spherical tip.

[0015] The surface of the second tip is one of a flat cylindrical surface, an oblique cylindrical surface or a curved surface.

[0016] Beneficial effects of the present invention:

[0017] The gyroscope proposed by the present invention, in a combat collision, when the gyroscope is rotating, when the rod is hit, it drives the central axis to slide, thereby causing the tip of the gyroscope to switch between a first tip and a second tip; through continuous collisions, the tip of the gyroscope changes irregularly, thereby changing the motion trajectory of the gyroscope on the spherical combat disk; when the first tip extends out of the shaft hole, the gyroscope rotates on the bottom of the spherical combat disk and is in a defensive state; when the first tip is retracted into the shaft hole, the outer edge of the lower end of the shaft hole becomes the tip of the gyroscope, and due to the change in the contact point between the spherical combat disk and the second tip, the gyroscope wanders on the wall of the spherical combat disk and is in an attacking state; the variable motion trajectory makes the gyroscope more exciting and vivid during the battle on the spherical combat disk, enhancing the interest and entertainment.

[0048] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the drawings only show portions relevant to the present invention, not all of them.

[0049] Example 1

[0050] See also Figures 1 to 15An embodiment of the present invention provides a gyroscope, comprising a fixed surface cover 1 and a bottom cover 2, wherein a central axis 4 that can slide along a first direction is provided at the center of the surface cover 1 and the bottom cover 2, and an axis hole is provided at the center of the bottom cover 2. The central axis 4 is inserted into the axis hole and can slide along the axis hole. The first direction is the extension direction of the axis hole, and the lower end of the central axis 4 is a first gyroscope tip 41; a rod 5 is provided between the surface cover 1 and the bottom cover 2, and the rod 5 can slide along a second direction under the action of an external force and slidably cooperate with the central axis 4. The rod 5 slides along the second direction to push the central axis 4 to slide along the first direction, so that the first gyroscope tip 41 extends out of or retracts into the axis hole, and the gyroscope tip switches between the first gyroscope tip 41 and the second gyroscope tip 31, and the first direction is perpendicular to the second direction.

[0051] During a combat collision, when the gyroscope is rotating, when the rod 5 is hit, the rod 5 slides in the second direction, driving the central axis 4 to slide in the first direction, thereby causing the tip of the gyroscope to switch between the first tip 41 and the second tip 31; through continuous collisions, the tip of the gyroscope changes irregularly, thereby changing the motion trajectory of the gyroscope on the spherical combat disk 10; when the first tip 41 extends out of the shaft hole, the gyroscope rotates on the bottom of the spherical combat disk 10 and is in a defensive state; when the first tip 41 retracts into the shaft hole, the outer edge of the lower end of the shaft hole becomes the tip of the gyroscope, and due to the change in the contact point between the spherical combat disk 10 and the second tip 31, the gyroscope wanders on the wall of the spherical combat disk 10 and is in an attacking state; the changeable motion trajectory makes the gyroscope more exciting and vivid during the battle in the spherical combat disk 10, enhancing the fun and entertainment.

[0052] Of course, a shaft sleeve 3 may also be provided at the center of the bottom cover 2 , with the shaft hole being opened on the shaft sleeve 3 .

[0053] After installation, at least one end of the rod 5 is exposed from the outer surface of the gyroscope, allowing the rod 5 to be impacted. When the first end 51 of the rod 5 is exposed from the outer surface of the gyroscope, if the first end 51 is impacted, the rod 5 slides in the second direction, causing the second end 52 of the rod 5 to be exposed from the outer surface of the gyroscope. If the second end 52 is impacted, the rod 5 slides in the opposite direction of the second direction. This cycle repeats, with the rod 5 sliding in the second direction, thereby causing the central shaft 4 to retract or extend from the sleeve 3.

[0054] A release member 6 is connected to the top of the cover 1 to facilitate the rotation of the top. A flywheel 7 is located between the cover 1 and the bottom cover 2 to enhance the stability and durability of the top. During launch, the flywheel 7 rotates synchronously with the top. Due to its large moment of inertia, it stores the kinetic energy of the top's rotation. When the top's tip strikes the ground, the flywheel 7 releases this energy, allowing the top to continue rotating due to inertia.

[0055] See also Figures 6 to 9The front cover 1 is provided with a plurality of protrusions 11 around its center. The bottom cover 2 is provided with engaging holes 21 at positions corresponding to the protrusions 11. A protrusion 71 is provided on the flywheel 7 at a position corresponding to the protrusion 11. The protrusion 71 has a through hole 72 formed therein. The protrusion 11 passes through the through hole 72 and engages with the engaging hole 21, thereby sandwiching the protrusion 71 between the front cover 1 and the bottom cover 2. In this embodiment, four protrusions 11 are provided around its center on the front cover 1.

[0056] See also Figure 4 and Figure 8 The bottom cover 2 is provided with a slideway 22 for accommodating the rod 5. Limiting flanges 23 are provided on both sides of the slideway 22. The lower end of the rod 5 contacts the bottom cover 2. When the end of the rod 5 is hit, the limiting flanges 23 limit the rod 5 and allow it to slide within the slideway 22.

[0057] See also Figure 1 and Figure 7 The upper end of the cover 1 is symmetrically provided with two spiral surfaces 12 for easy installation of the release member 6. By rotating the release member 6, the gyroscope is driven to rotate. The release member 6 can be released manually or by a releaser, which is not limited here.

[0058] See also Figure 10 and Figure 11 A accommodating cavity is opened in the middle of the rod 5, and a limited position surface is set in the accommodating cavity. The limited position surface includes a first plane 53 and a second plane 54 which is stepped with the first plane 53. The first plane 53 and the second plane 54 are smoothly transitioned by an inclined surface 55.

[0059] A protrusion 42 is formed around the central axis 4, and the end surface of the protrusion 42 abuts against the limiting surface. The end surface of the protrusion 42 can abut against the first flat surface 53. When the rod 5 slides in the second direction, the limiting surface pushes the central axis 4 to move, causing the protrusion 42 to slide along the inclined surface 55 until the end surface of the protrusion 42 abuts against the second flat surface 54.

[0060] In this embodiment, the lower end surface 421 of the protrusion 42 abuts the limiting surface, and a first spring 8 is disposed between the protrusion 42 and the cover 1. A first step is provided within the cover 1. One end of the first spring 8 abuts the upper end surface 422 of the protrusion 42, while the other end abuts the first step. The lower end surface 421 of the protrusion 42 is the end surface of the protrusion 42 that is closest to the first tip 41.

[0061] When the first tip 41 of the central shaft 4 extends out of the sleeve 3, the lower end surface 421 of the protrusion 42 abuts the first flat surface 53. When the first end 51 of the rod 5 is struck and slides in the second direction, the limiting surface pushes the central shaft 4 to slide in the first direction, causing the protrusion 42 to slide along the inclined surface 55 until the end surface of the protrusion 42 abuts the second flat surface 54. The first spring 8 is compressed, and the first tip 41 of the central shaft 4 retracts into the sleeve 3. The second tip 31 replaces the first tip 41. When the second end 52 of the rod 5 is struck, the restoring force of the first spring 8 causes the protrusion 42 to slide along the inclined surface 55 until the end surface of the protrusion 42 abuts the first flat surface 53, and the first tip 41 of the central shaft 4 extends out of the sleeve 3. The provision of the first flat surface 53 and the second flat surface 54 facilitates limiting the position of the central shaft 4 in the first direction.

[0062] The first top 41 is a spherical top. When the spherical top is in the position of the top, the top can rotate quietly at the bottom of the spherical battle disk 10 and is in a defensive state.

[0063] When the first top 41 contacts the spherical battle disk 10 , since the first top 41 is a spherical top, the contact point between the gyroscope and the concave spherical surface of the spherical battle disk 10 is located on the center line of the central axis 4 , so that the gyroscope will only rotate quietly at the bottom end of the spherical battle disk 10 .

[0064] See also Figure 4 、 Figures 12 to 15 The shaft sleeve 3 is detachably connected to the bottom cover 2, facilitating installation and replacement. A protrusion 32 is provided on the side of the shaft sleeve 3. The lower end of the protrusion 32 abuts the bottom cover 2, while the upper end of the shaft sleeve 3 abuts the rod 5. The shaft sleeve 3 is detachably connected to the bottom cover 2, facilitating installation and replacement. Of course, the shaft sleeve 3 can also be integrally formed with the bottom cover 2.

[0065] The outer edge of the lower end of the sleeve 3 serves as the second top 31, and its shape can be customized according to actual needs. Different shapes of the second top 31 allow the gyroscope to have different motion trajectories, enriching the gyroscope's functionality and adding more fun. When the second top 31 wears out, or if you want to change the gyroscope's trajectory, the sleeve 3 can be replaced.

[0066] The surface of the second tip 31 is a flat cylindrical surface, an oblique cylindrical surface, or a curved surface. When the second tip 31 is a curved surface, it can be a concave cylindrical surface. Of course, the surface of the second tip 31 can also be other shapes, which are not limited here.

[0067] When the second top tip 31 contacts the spherical battle disk 10, since the outer edge of the lower end of the sleeve 3 deviates from the center line of the central axis 4, the gyroscope becomes a gyroscope with its top tip deviating from the center line of the gyroscope, thereby causing the gyroscope to rotate around the center line of the spherical battle disk 10 within the concave spherical surface of the spherical battle disk 10.

[0068] Example 2

[0069] Figures 16 to 19 A second embodiment is shown, wherein components identical or corresponding to those in the first embodiment are numbered accordingly. For simplicity, only the differences between the second embodiment and the first embodiment are described. These differences are that the upper end surface 422 of the protrusion 42 abuts against the stop surface, and a second spring 9 is provided between the protrusion 42 and the shaft sleeve 3.

[0070] A second step portion is provided in the shaft sleeve 3 , and one end of the second spring 9 abuts against the lower end surface 421 of the protrusion 42 , and the other end abuts against the second step portion.

[0071] When the first tip 41 of the central shaft 4 is retracted into the sleeve 3, the upper end surface 422 of the protrusion 42 abuts against the first plane 53; when the first end 51 of the rod 5 is hit and slides along the second direction, the limiting surface pushes the central shaft 4 to slide along the first direction, so that the protrusion 42 slides along the inclined surface 55 until the end surface of the protrusion 42 abuts against the second plane 54, the second spring 9 is compressed, and the first tip 41 of the central shaft 4 extends out of the sleeve 3; when the second end 52 of the rod 5 is hit, under the action of the restoring force of the second spring 9, the protrusion 42 slides along the inclined surface 55 until the end surface of the protrusion 42 abuts against the first plane 53, the first tip 41 of the central shaft 4 is retracted into the sleeve 3, and the second tip 31 replaces the first tip 41.
