The wheel body 1 and the wheel core 2 are assembled into a whole, in different embodiments, three assembly modes of the wheel body 1 and the wheel core 2 are adopted, one of the assembly modes is that special glue is used for bonding, the wheel body 1 and the wheel core 2 are adhered to each other by a holding surface in the bonding mode, and are pressed and fixed after being glued on the adhering surface, the assembly mode has simple process, and has lower structural requirements on the wheel body 1 and the wheel core 2, and the wheel body 1 is assembled into a low-cost implementation mode, and the other embodiment is that an embedded structure is arranged, the wheel body 1 is embedded and molded by a hot-pressing method, the assembly mode can bear multidirectional force, has good durability and slightly complex process, and the embodiment adopts a third assembly molding mode, and the mode is the combination of the two modes:
In this embodiment, the wheel core 2 is provided with an annular insertion groove on two sides of the outer edge of the corresponding disc surface, the annular insertion groove is used as an assembly structure, the wheel body 1 is integrally assembled at the outer disc surface position of the wheel core 2, the wheel body 1 is provided with an insertion seat 10 which is annular and matched with the annular insertion groove, during assembly, a layer of YH-818 adhesive is coated in the annular insertion groove of the wheel core 2, then the wheel body 1 is assembled in an embedded manner at the annular insertion groove position in a hot press assembly mode by taking the wheel core 2 as a base, the insertion seat 10 is pressed into the annular insertion groove with the adhesive, and the wheel structure for the sliding plate assembled into a whole is obtained after the adhesive is cured.
The wheel body 1 is made of polyurethane materials with the hardness of 80-88A in an integral mode, the wheel body 1 is assembled and connected with the outer disc surface of the wheel core 2 into a whole, three layers of cavity structures are respectively formed on the annular surface of the wheel body 1 through the first diaphragm 4 and the second diaphragm 11 from inside to outside, the inner layer cavity is a separation cavity, the separation cavity is located between the outer disc surface of the wheel core 2 and the second diaphragm 11 after the assembly and connection of the wheel body 1 and the wheel core 2 are achieved, the separation cavity is of an annular flat cavity structure, the cavity thickness of the flat cavity continuously decreases from the middle to two sides on the cavity section, and in the assembly and molding process of the wheel body 1 and the wheel core 2, single-component liquid silicone rubber with the viscosity range of 25000-30000 Pa.S is filled in the flat cavity as a buffer medium.
The structure of the middle layer cavity in the wheel body 1 is shown in fig. 2, the middle layer cavity is positioned between the first diaphragm 4 and the second diaphragm 11 and corresponds to 45% of the ring diameter of the wheel body, the middle layer cavity area comprises eight preset air bag cavities 5 which are annularly arranged, the preset air bag cavities 5 adjacent to each other in position are separated by ribs 12 integrally formed with the wheel body 1, and high-pressure gas of 2.0+/-0.1 bar is filled in the eight preset air bag cavities 5, so that each preset air bag cavity 5 has independent buffer performance. The outer layer cavity structure in the wheel body 1 comprises a plurality of independent capsule cavities 3, the structural style of the capsule cavities 3 after being tiled on a plane is shown as a figure 3, the capsule cavities 3 are long water drop-shaped capsule cavities, the thickness of the cavity corresponds to 17% of the ring diameter of the wheel body, and the capsule cavities are staggered on the ring surface corresponding to the outer layer cavity according to the style shown as the figure 3.
Under the technical condition of the embodiment, when the wheel body 1 receives the front impact force, the wheel body can sequentially pass through the capsule cavity 3, the preset air bag cavity 5 and the non-Newtonian fluid 6 for three times to buffer, the impact resistance of the wheel surface can be effectively improved by matching with the integrally formed wheel body structure, and the elastic output is also more stable.

Compared with the buffer capsule cavity structures with other regular structures, the long water drop-shaped structure of the capsule cavity 3 is more suitable for absorbing side impact force, so that the long water drop-shaped structure can buffer the side force of the wheel body 1 under the condition that the outer edge side force of the wheel body 1 is possibly caused in the swinging process of the sliding plate body, the stressed state is shown in fig. 4, when the side force of one side acts on the big head side of the capsule cavity 3, the acting force can absorb a part of kinetic energy by a cavity medium (such as air or other elastic materials) of the capsule cavity 3, and the kinetic energy generated by the other part of stress is outwards expanded at two sides of the small head side of the corresponding capsule cavity 3 in the arrow direction as shown in the figure and is secondarily absorbed by two capsule cavities 3 adjacent to the position, and the stressed state of the side of the capsule cavity 3 can be effectively reduced, so that the probability of side turning of the sliding plate in the large swing process of the plate surface is reduced.
In summary, the wheel for skateboards of the embodiment has the advantage that the wheel is more suitable for realizing high-difficulty and high-precision skateboard actions due to the stress characteristics of the wheel which is obviously due to the usability of the traditional polyurethane potting wheel or other integrally formed solid wheels on the market, so that the wheel is more suitable for the depth customization improvement of middle-end skateboard players and high-end skateboard players or professional players.
In this embodiment, the corresponding capsule cavity 3 is a normal pressure hollow cavity to accommodate a ground structure having a flexible layer or a plastic layer, such as a wooden ground, a plastic ground, an asphalt ground, etc. In yet other embodiments, the corresponding capsule 3 is filled with butyl rubber blocks of the same size as the capsule to accommodate rigid floor structures such as cement floors.
In this embodiment, considering that the outer edge portion of the wheel core 2 may be deformed by compression when the side face of the wheel body 1 is stressed, the wheel body 1 of this embodiment is provided with an outer wrapping edge 9 at the outer edge of the base portion to wrap the wheel core 2 structurally, so as to reduce impact damage and friction damage caused when the side edge of the wheel core 2 collides.
