In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.
The specific structure of the spin ball 1 according to the embodiment of the present application is described below with reference to fig. 1 to 10.
As shown in fig. 2, the spin ball 1 according to the embodiment of the present application includes a ball body 10, a disc body 20, a fixed core 30, and an elastic energy storage member 40. The ball 10 is provided with a rotary cavity 140, the fixed core 30 is arranged in the rotary cavity 140, two ends of the fixed core 30 are respectively connected with the ball 10, the rotation angular speed of the fixed core 30 relative to the ball 10 is zero, that is, no relative rotation exists between the fixed core 30 and the ball 10, and therefore no friction resistance exists between the fixed core 30 and the ball 10.
The tray 20 is located in the rotary cavity 140, a movable cavity 230 is provided in the tray 20, through holes are provided on opposite side walls of the tray 20, and the tray 20 is rotatably sleeved on the fixed core 30 through the through holes on both sides. It can be said that the fixed core 30 is provided in the tray body 20, both ends of the fixed core 30 protrude from two through holes of the tray body 20, respectively, and both ends of the fixed core 30 are connected to the ball 10, respectively, and are configured to be synchronized with the ball 10 in the circumferential direction.
Wherein, the inner peripheral wall of at least one through hole on the tray 20 is in point contact or line contact with the outer peripheral wall of the fixed core 30. It will be appreciated that, according to the foregoing, there is a contact between the inner peripheral wall of the through hole and the outer peripheral wall of the stationary core 30 where friction exists during rotation of the disc 20, and therefore, the friction force can be reduced by making the inner peripheral wall of the disc 20 with one through hole or two through holes in point contact or line contact with the outer peripheral wall of the stationary core 30, thereby enabling the disc 20 to rotate more smoothly.
In the present application, the elastic energy storage member 40 is disposed in the movable cavity 230, the elastic energy storage member 40 is respectively connected with the fixed core 30 and the tray body 20, and the elastic energy storage member 40 stores energy or releases energy when the tray body 20 rotates relative to the fixed core 30. For example, when the tray 20 rotates forward relative to the fixed core 30 under the action of an external force, the external force can be converted into the force of the elastic energy storage member 40. When the elastic energy storage member 40 releases energy, the elastic energy storage member 40 can drive the disk body 20 to rotate reversely relative to the fixed core 30, and the potential energy is converted into kinetic energy of the disk body 20.
It will be appreciated that since the two ends of the fixed core 30 are respectively connected to the ball 10 and are configured to be circumferentially synchronized with the ball 10, that is, a rotational friction force cannot exist between the end surface of the fixed core 30 and the ball 10, during the rotation of the disk 20 of the swivel ball 1, only a friction surface exists between the fixed core 30 and the disk 20, thus greatly reducing the friction force to which the disk 20 is subjected. In the playing process of the spin 1 according to the embodiment of the present application, when a user throws out the spin 1, the disc 20 rotates relative to the fixed core 30, and the disc 20 is spaced from the inner wall of the ball 10. Therefore, in the rotating process of the spin 1, the contact surface with friction is the contact surface between the outer peripheral surface of the fixed core 30 and the inner wall surface of the through hole of the disk body 20, so that friction resistance of the disk body 20 during rotation is greatly reduced, a player feels smoother during playing, more actions can be completed, and the spin 1 of the embodiment of the application is easier for a primary player to get on hand. In addition, since the fixed core 30 and the ball 10 are relatively fixed, the ball 10 has better integrity and more stable structure in the process of rotating the spin 1, and the playability of the spin 1 is further improved.
According to the spin 1 of the embodiment of the present application, since the fixed core 30 is fixed relative to the ball body 10, the disk body 20 only receives the friction resistance from the fixed core 30 during the rotation process, so that the spin 1 can rotate more smoothly, the player feel more smoothly during playing, more actions can be completed, and the spin 1 of the embodiment of the present application is easier for the primary player to get on hand.
In addition, since the fixed core 30 and the ball 10 are relatively fixed, the ball 10 is more stable during the rotation of the spin 1, and the playability of the spin 1 is further improved.
It should be noted that the elastic energy storage member 40 may be a coil spring, a disc spring, or the like, and the elastic energy storage member 40 is not particularly limited in the embodiment of the present application.
In some embodiments, as shown in fig. 3, the axial cross-section of at least one through hole has the shape of two circular arcs protruding toward each other, the protruding circular arc portions being tangential to the stationary core 30. Thus, the inner peripheral walls of the two through holes on the tray 20 and the outer peripheral wall of the fixed core 30 are in line contact. Of course, a plurality of circular arc-shaped protrusions can be arranged on the inner peripheral wall of the through hole at intervals, or a plurality of zigzag spines are arranged on the inner peripheral wall of the through hole at intervals, so that point contact between the inner peripheral wall of one through hole or two through holes on the tray body 20 and the outer peripheral wall of the fixed core 30 can be realized. It should be noted that the above-mentioned forms are only examples for realizing the point contact or the line contact between the inner peripheral walls of the two through holes on the tray body 20 and the outer peripheral wall of the fixed core 30, and are not limited to the shape of the through holes, and any through hole structure that ensures the point contact or the line contact between the inner peripheral wall of at least one through hole on the tray body 20 and the outer peripheral wall of the fixed core 30 is within the scope of the present application.
In some embodiments, as shown in fig. 3, the disc 20 is provided with a chamfer or rounded corner at each end of at least one through hole. It will be appreciated that when the disc 20 is stationary, the end surface of the through-hole of the disc 20 will be in contact with the axial surface of the stationary core 30, and the magnitude of this contact surface will affect the magnitude of the maximum static friction between the disc 20 and the stationary core 30, that is, the magnitude of this contact surface will be directed to the magnitude of the initial driving force for driving the disc 20 to rotate. Therefore, the two ends of each through hole on the disc body 20 can be provided with chamfers or fillets, so that the contact surface area between the end surface of the through hole of the disc body 20 and the axial surface of the fixed core 30 can be reduced, the static friction force between the end surface of the through hole and the axial surface of the fixed core 30 is further reduced, the initial driving force for driving the disc body 20 to rotate is reduced, and a player can drive the spin ball 1 to rotate more conveniently.
In some embodiments, the tray 20 is sleeved on the fixed core 30 and has a certain space from two ends of the fixed core 30 in the axial direction, so that the tray 20 can slide in the axial direction of the fixed core 30, and the tray 20 contacts with the fixed core 30 only at the inner peripheral wall of the through hole when the tray 20 rotates relative to the fixed core 30, but not with two ends of the fixed core 30. Specifically, as shown in fig. 4, the S1 end surface on the fixed core 30 is separated from the S2 end surface of one through hole of the disc body, and the S3 end surface on the fixed core 30 is separated from the S4 end surface of the other through hole of the disc body 20, which means that if a radial contact surface exists between the disc body 20 and the fixed core 30 during rotation of the disc body 20, the fixed core 30 will apply a friction moment to the disc body 20, and this friction moment will prevent rotation of the disc body 20, so that when the disc body 20 rotates relative to the fixed core 30, the disc body 20 contacts with the fixed core 30 only at the inner peripheral wall of the through hole, that is, the fixed core 30 does not contact with the disc body 20 in the radial direction during rotation of the disc body 20, so that the friction force suffered by the disc body 20 can be further reduced, and the hand feeling of a player during playing is improved.
In some embodiments, grooves are formed on opposite sidewalls of the rotating cavity 140, and two ends of the fixed core 30 are respectively fitted into the corresponding grooves. The connection between the fixed core 30 and the sphere 10 can thus be achieved, which is relatively simple in construction and does not require additional connectors.
Specifically, at least one groove is configured to be non-circular, and the end of the stationary core 30 conforms to the shape of the groove. Therefore, the ball 10 and the fixed core 30 can be mutually fixed, the structure for limiting the relative rotation of the fixed core 30 and the ball 10 by adopting the noncircular grooves is very simple, other limiting parts are not needed, the structure of the ball 10 is simplified, and the production cost of the spin ball 1 is reduced. Of course, the fixed core 30 may be connected to the ball 10 by other connection means such as screw connection.

The latch 321 is inserted into the latch groove 3141 to latch the elastic energy storage member 40. Thereby, the elastic energy storage member 40 can be prevented from being separated from the clamping groove 3141, and the normal rotation of the spin ball 1 can be ensured.
Specifically, as shown in fig. 2, the fixed core 30 includes a fixed disk 320, the fixed disk 320 is sleeved on the main core 310, and the latch 321 is provided on the fixed disk 320. It should be noted that, the fixing plate 320 may be integrally formed on the fixing core 30, or may be a single member having a connection relationship with the fixing core 30.
