Description

Technical Field

[0001] This utility model relates to the field of spheres, and in particular to a land-based sphere cake. Background Technology

[0002] Ice hockey, also known as ice hockey, originated in Canada in the mid-19th century. It was originally created by moving hockey to ice and combining the characteristics of "lacrosse". Ice hockey is a competitive team sport played on ice using ice skates and hockey sticks.

[0003] Ice hockey requires playing on ice, which demands high precision. Due to limitations of the playing surface, land hockey was developed, a variation of ice hockey played on land. Currently, specific land hockey pucks have been developed specifically for this sport.

[0004] In addition, hockey is a ball sport played on different surfaces, mainly including ice hockey, grass hockey, and roller hockey. In grass hockey and roller hockey, land-based ball pie can also be used for corresponding training.

[0005] Currently, commercially available land-based sports beanbags have several problems. First, excessive friction with the ground results in short travel distances and significant resistance during ground movement, leading to a less smooth and fluid motion. Second, their center of gravity is unstable, causing instability in flight and a tendency to tilt to one side, resulting in a rapid landing. These issues all negatively impact the smoothness and controllability of the movement when using land-based sports beanbags, significantly reducing the overall experience.

[0006] Against this background, the present invention proposes a new technical solution. Utility Model Content

[0007] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a land-based earth-shaped cake, and the technical solution adopted is as follows:

[0008] A type of earth-shaped pastry includes a central pastry block, with side pastry blocks connected to both sides of the central pastry block. A plurality of ball bearings are sandwiched between the central pastry block and the side pastry blocks. Each ball bearing has at least a portion extending through the side pastry block and protruding outside the side pastry block, and each ball bearing can rotate freely when subjected to force.

[0009] According to an embodiment of the present invention, a land-based earth cake has a counterweight block in the middle of the middle cake block.

[0010] According to an embodiment of the present invention, a plurality of rolling balls are arranged in a ring on both sides of a middle cake block and are distributed in a ring on the outer circumference of the middle cake block.

[0011] According to an embodiment of the present invention, a type of earth-shaped cake has multiple grooves for placing ball bearings on both end faces of the middle cake block.

[0012] According to an embodiment of the present invention, a land-based earth cake has multiple through holes on the side cake block, each through hole corresponding to a groove, and the through holes allow the ball bearing portion to be exposed outside the side cake block.

[0013] According to an embodiment of the present invention, a type of earth-shaped cake is provided, wherein the side of the through hole facing the middle cake block is defined as the inner diameter, and the side away from the middle cake block is defined as the outer diameter.

[0032] This utility model provides a land-based earth cake, such as Figure 1 , 2 As shown in Figures 3 and 4, the device includes a central disc block 10, with side disc blocks 20 connected to both sides of the central disc block 10. A plurality of ball bearings 30 are clamped between the central disc block 10 and the side disc blocks 20. Each ball bearing 30 has at least a portion extending through the side disc block 20 and protruding outside the side disc block 20. Each ball bearing 30 can rotate freely after being subjected to force.

[0033] This invention features ball bearings 30 positioned between the central disc block and the side disc blocks. These ball bearings 30 are partially exposed and directly contact the ground during impact. The ball bearings 30 can rotate freely, converting sliding friction into rolling friction, significantly reducing ground resistance, increasing gliding distance and smoothness, and avoiding the sluggishness caused by the rigid friction of traditional discs. Furthermore, the ball bearings 30 are evenly distributed between the central disc block 10 and the side disc blocks 20, forming a multi-point support structure. During movement, the ball bearings 30 can balance the center of gravity, reducing the risk of tilting and enhancing flight stability. The land-based disc provided by this invention effectively improves the smoothness and controllability of the movement, significantly enhancing the sports experience.

[0034] Furthermore, in the embodiments of this utility model application, such as Figure 3 , 4 As shown, a counterweight 40 is provided in the middle of the intermediate disc 10. In this embodiment, the design of adding a counterweight 40 in the middle of the intermediate disc 10 further optimizes the dynamic stability and motion performance of the land disc, significantly improving its flight stability. It has the advantages of centralized center of gravity and inertial control. The counterweight 40 concentrates the mass at the geometric center of the land disc, reducing torque imbalance (such as tilting or tumbling) caused by uneven mass distribution during flight. It is especially suitable for high-speed rotation scenarios. By adjusting the mass of the counterweight 40, the angular momentum of the disc can be controlled, allowing it to maintain axial stability after being thrown.

[0035] Furthermore, in the embodiments of this utility model application, such as Figure 1 , 2As shown in Figures 3 and 4, multiple balls 30 arranged in a ring on both sides of the central disc 10 are distributed on the outer circumference of the central disc 10. This design further optimizes the mechanical properties and motion stability of the land disc: the ring arrangement of the balls 30 ensures that when the disc rolls on the ground, the contact point is always shared by multiple balls 30, avoiding local overload and significantly reducing friction loss; the ring layout ensures that the disc is supported by balls 30 when rolling in any direction, which is suitable for complex terrain (such as slopes and uneven ground); the symmetrical distribution of the balls 30 offsets the centrifugal force deviation during rotation, preventing the disc from swaying or tilting due to uneven mass during flight; the ring array of balls 30 can disperse the impact force during collision (similar to a "bearing buffer structure"), reducing the risk of deformation of the side discs 20.

[0036] Furthermore, in the embodiments of this utility model application, such as Figure 1 , 2 As shown in Figures 3 and 4, multiple grooves 11 for placing ball bearings 30 are respectively provided on both end faces of the middle block 10. Multiple through holes 21 are provided on the side block 20, each through hole 21 corresponding to each groove 11. The through holes 21 allow a portion of the ball bearing 30 to be exposed outside the side block 20. The above design achieves precise positioning of the ball bearing 30. The middle block 10 and the side block 20 are assembled through the grooves 11-ball bearings 30-through holes 21, which facilitates separate injection molding during production and reduces mold complexity.

[0037] Furthermore, in the embodiments of this utility model application, the side of the through hole 21 facing the middle pie block 10 is defined as the inner diameter, and the side away from the middle pie block 10 is defined as the outer diameter. The inner diameter of the through hole 21 is larger than the outer diameter to limit the ball 30 between the side pie block 20 and the middle pie block 10. This can both limit the ball 30 between the side pie block 20 and the middle pie block 10 and allow the ball 30 to rotate freely.

[0038] Furthermore, in the embodiments of this utility model application, such as Figure 1 , 2 As shown in Figures 3 and 4, the outer end face of the side block 20 is provided with a raised platform 22 at the position corresponding to each through hole 21.

[0039] Furthermore, in the embodiments of this utility model application, such as Figure 3 , 4As shown, a central through hole 12 is provided in the middle of the central disc 10, and the counterweight 40 is disposed in the central through hole 12. The inner diameter of the central through hole 12 is larger than the outer diameter of the counterweight 40, and the distance from the outer end face of both sides of the central through hole 12 to the inner end face of the side disc 20 is greater than the height of the counterweight 40. This allows the counterweight 40 to move slightly within the central through hole 12 and also to move slightly between the side discs 20. Thus, when the land-based earth disc is in flight, the counterweight 40 can perform small-amplitude dynamic balance, greatly improving flight stability and further optimizing the dynamic stability and motion performance of the land-based earth disc.

[0040] Furthermore, in an embodiment of this utility model application, the two side pieces 20 are connected and fixed by a rubber layer.

[0041] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
