The technical scheme of the application is described in detail by the following specific embodiments:

as shown in fig. 1 to 14, in this embodiment, the gyroscope of the present invention includes a gyroscope main body and a driving disk 1 that can rotate relative to the gyroscope main body, the gyroscope main body and the driving disk 1 have the same shape, and the gyroscope main body and the driving disk 1 can be overlapped with each other to form an irregular shape of the gyroscope, or the gyroscope main body and the driving disk 1 can complement each other at a specific angle to form a revolving body shape.

In the scheme, the shapes of the gyroscope main body and the driving disc 1 are the same, and both do not have the outline of the revolving body, when the two are completely overlapped in the direction perpendicular to the contact surface of the two, the outline (the impacted appearance surface) of the gyroscope is also not provided with the outline of the revolving body, which is equivalent to forming a convex impact point on the surface of the gyroscope, and when the gyroscope is impacted, the impact point is easier to generate larger attack force; when the two parts are observed in the direction perpendicular to the contact surfaces of the two parts to form complementation, the outline of the gyroscope (the impacted appearance surface) forms the outline of the revolving body, and the outer surface of the outline of the revolving body is not provided with a convex structure, so the impact force is relatively balanced, and the impact effect is relatively weak.

This scheme can reach the attack effect of top when changing the fight through the outward appearance form that changes the top, through the in-process that uses the top to carry out the fight through above-mentioned setting, driving-disc 1 receives striking it can take place to rotate for the top main part, when it rotate with when the top main part is coincident each other, will be able to externally produce great impact, improves attack effect, and when it rotate with when the top main part is complemented each other, its solid of revolution state can guarantee that the stability that the top spiral changes is higher, more does benefit to and realizes the defense. And the conversion of the process is automatically realized in the fighting process completely, and the gyro does not need to be considered to participate in the operation after the gyro starts to operate, so that the fighting randomness can be improved, and the ornamental value and the entertainment value can be enhanced.

Specifically, in this embodiment, the top body has a collision disk, an outline of the collision disk is an outline of the top body, and an outline of the driving disk 1 is the same as an outline of the collision disk.

The collision disc and the driving disc 1 respectively comprise four arc-shaped edges and four straight edges, the arc-shaped edges and the straight edges are arranged in a staggered mode, and the chord length corresponding to each arc-shaped edge is equal to the length of each straight edge.

In the scheme, the collision disk and the driving disk 1 are both arranged in symmetrical and regular shapes, so that the collision disk and the driving disk are mutually in a complementary state to form a revolving body outline.

Specifically, a plurality of driving pieces 11 are arranged on the driving disc 1, a limiting groove 12 is formed between the adjacent driving pieces 11, a plurality of limiting protrusions are arranged on the gyroscope main body and correspond to the limiting groove 12, the limiting groove 12 is matched with the limiting protrusions to achieve temporary locking between the driving disc 1 and the gyroscope main body, and the driving disc 1 and the gyroscope main body are in a superposition state or a complementary state in the temporary locking state.

Preferably, in this embodiment, the gyroscope main body is provided with a first gyroscope tip 2 and a second gyroscope tip 3 which is retractable relative to the first gyroscope tip 2, a reset element 4 which can enable the second gyroscope tip 3 to move in a first direction along an axis of the first gyroscope tip 2 is arranged between the second gyroscope tip 3 and the gyroscope main body, and the driving disc 1 is provided with a driving element 11 which can drive the second gyroscope tip 3 to move in a second direction opposite to the first direction along the axis of the first gyroscope tip 2.

In the running process of the gyroscope, the gyroscope body is supported by the first gyroscope tip 2 in the initial state, at the moment, the gyroscope moves according to the running track corresponding to the first gyroscope tip 2 according to the shape of the first gyroscope tip 2, when the driving disc 1 which can rotate relative to the gyroscope body rotates until the driving element 11 is abutted to the second gyroscope tip 3, the driving element 11 pushes the second gyroscope tip 3 to move towards the second direction along the axis of the first gyroscope tip 2, at the moment, the reset element 4 is compressed, when the action of the driving element 11 on the second gyroscope tip 3 reaches the maximum value, the second gyroscope tip 3 replaces the first gyroscope tip 2 to support the gyroscope body, because the shape of the second gyroscope tip 3 is different from that of the first gyroscope tip 2, and after the second gyroscope tip 3 replaces the first gyroscope tip 2, because the shape of the gyroscope tip is changed, the friction force generated when the gyroscope moves on the combat disc is changed, the gyroscope moves according to the running track corresponding to the second gyroscope tip 3, so that the effect of changing the running track of the gyroscope is achieved.

When the driving disc 1 continues to rotate relative to the gyroscope main body, after the driving element 11 loses the action on the second gyroscope tip 3, the second gyroscope tip 3 moves towards the first direction along the axis of the first gyroscope tip 2 under the action of the reset element 4, the first gyroscope tip 2 replaces the second gyroscope tip 3, the supporting on the gyroscope main body is realized again, and the gyroscope recovers to move according to the running track corresponding to the first gyroscope tip 2.

So, along with driving-disc 1 is for the rotation of top main part, be used for supporting top main part's top point to circulate between first top point 2 and second top point 3 and switch, and then correspond the motion of the orbit of first top point 2 and second top point 3 in turn, the change of top orbit has increased the uncertainty of top motion, has improved practicality, recreational, the object for appreciation nature of top, can satisfy more user's demands.

The external contour dimension of the driving disk 1 is larger than or equal to the external contour dimension of the gyro body, and the rotation of the driving disk 1 relative to the gyro body is realized by the collision of the driving disk 1.

Specifically, in this embodiment, the external dimensions of the driving disc 1 and the external dimensions of the gyroscope main body are the same, and the rotation of the driving disc 1 relative to the gyroscope main body is realized by the collision of the driving disc 1, that is, the outer side surface of the driving disc 1 is flush with the outer surface of the gyroscope main body, at this time, under the condition that the gyroscope collides with a foreign object (a mutually-fighting gyroscope, a wall, etc.), the driving disc 1 rotates relative to the gyroscope main body, so as to realize the function of replacing the gyroscope tip.

In the running process of the gyroscope, the driving disc 1 and the gyroscope main body move synchronously, when collision occurs, if the driving disc 1 is collided independently, the rotating state of the driving disc is affected by the friction force generated by the collision effect, the rotating state of the gyroscope main body which is not collided is kept unchanged, the two rotating states are not consistent, and therefore the driving disc 1 and the gyroscope main body rotate relatively.

Similarly, if the main body of the spinning top is collided alone, the rotation state of the driving disk 1 remains unchanged under the inertia effect, but the motion state of the main body of the spinning top is affected, and the motion states of the driving disk 1 and the main body of the spinning top are not consistent any more, so that the relative motion of the driving disk 1 and the main body of the spinning top can also occur.

It should be noted that, the outline dimension of the driving disk 1 is not limited to be the same as that of the gyro body, and in other embodiments, the outline dimension of the driving disk 1 may also be larger than that of the gyro body, in this case, the driving disk 1 is mainly in contact with an impact object when the gyro is collided during operation, and since the proportion of the driving disk 1 in the gyro relative to the gyro body is small, the collision of the driving disk 1 can more easily cause the driving disk 1 and the gyro body to relatively rotate, so as to generate higher-frequency tip replacement.

In another embodiment, the outline dimension of the driving disk 1 can be set to be smaller than the outline dimension of the gyroscope main body, in this case, when the gyroscope runs and is collided, the gyroscope main body is mainly contacted with the collider to cause the change of the rotating state, and at the moment, the driving disk 1 keeps the original rotating state under the action of inertia, so that the relative rotation between the driving disk 1 and the gyroscope main body is realized, and the gyroscope tip can be replaced as well.

The driving parts 11 are arranged in a plurality, the driving parts 11 are arranged on the surface of the driving disc 1 facing the second gyroscope tip 3 at equal intervals, and a limiting rod 31 matched with the driving parts 11 is arranged on the gyroscope tip.

The specific process that the driving disc 1 drives the second gyroscope tip 3 to move is that, under the condition that the driving disc 1 (gyroscope main body) is subjected to external force and relatively rotates with the gyroscope main body (driving disc 1), the relative position between the driving part 11 positioned on the driving disc 1 and the limiting rod 31 positioned on the second gyroscope tip 3 is also changed, the driving part 11 and the limiting rod 31 are partially overlapped in the horizontal direction in the contraction state of the second gyroscope tip 3, the driving part 11 extrudes the limiting rod 31 to enable the limiting rod 31 to drive the second gyroscope tip 3 to move along the axis direction when the relative position is changed between the driving part 11 and the limiting rod 31, so that the second gyroscope tip 3 is extended, after the driving part 11 is positioned above the limiting rod 31, the limiting part does not extrude the limiting rod 31, and the second gyroscope tip 3 is restored to the contraction state under the action of the resetting element 4.

The number of driving members 11 determines the period of the gyroscopic transition between the first 2 and the second 3 gyroscopic tip.

Specifically, the driving member 11 in this embodiment has the following specific structure: the driving member 11 is provided with a first guide surface, and the limiting rod 31 is provided with a second guide surface matched with the first guide surface.

The movement of the driving disc 1 in the circumferential direction can be converted into the movement of the second gyroscope tip 3 in the axial direction by arranging the first guide surface and the second guide surface, and then the extension and retraction of the second gyroscope tip 3 are realized.
