[ detailed description ] embodiments

The technical solutions of the embodiments of the present invention are explained and explained below with reference to the drawings of the embodiments of the present invention, but the embodiments described below are only preferred embodiments of the present invention, and not all embodiments. Based on the embodiments in the embodiment, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

In the following description, the terms such as "inner", "outer", "upper", "lower", "left", "right", etc., which indicate orientations or positional relationships, are used for convenience in describing embodiments and simplifying description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

The first embodiment is as follows:

as shown in fig. 1 to 3, the present embodiment shows an inertia wheel for use in fitness equipment, which includes a wheel main body 1 and a weight member 2, wherein the wheel main body 1 is an injection molded body, an annular positioning groove 11 is formed in a circumferential outer ring of the wheel main body 1, the weight member 2 is an annular metal ring, the wheel main body 1 and the weight member 2 are integrally formed by an integral injection molding process, and the annular metal ring is embedded in the annular positioning groove 11.

Firstly, in the embodiment, the traditional all-metal inertia wheel is changed into the inertia wheel comprising the wheel main body 1 and the counterweight component 2, wherein the wheel main body 1 is made of plastic, so that the weight of the whole inertia wheel is greatly reduced, at least under the same size specification, the weight of the inertia wheel in the embodiment is far lower than that of the all-metal inertia wheel, and meanwhile, the counterweight component 2 is specially assembled for ensuring certain weight of the inertia wheel.

Secondly, in this embodiment, the weight member 2 is directly integrated with the wheel main body 1 through an integral injection molding process, so that the step of manual subsequent installation is omitted, obviously, the assembly process is simplified, and the weight member 2 after injection molding is embedded in the annular positioning groove 11, so that the positioning is stable and is not easy to separate.

Finally, because this embodiment adopts the injection molding on the material for the majority, the material cost can be reduced, simultaneously because the counter weight component 2 is directly moulded plastics on wheel main part 1, simplifies the installation step again, so the assembly cost is also lower, and the cost can fine control on the whole.

In addition, in order to further ensure the connection stability between the weight member 2 and the wheel main body 1, in this embodiment, the inertia wheel further includes an outer race 3, and the outer race 3 covers the weight member 2, so that a layer of protection limit is added to the radial outer portion of the weight member 2, in this embodiment, the outer race 3 is preferably an aluminum race, and is in interference fit with the weight member 2 during installation. In other embodiments, the outer race 3 may be interference-fitted to the wheel main body 1.

In order to further prevent the weight member 2 from radially escaping from the annular positioning groove 11, in the present embodiment, a stopper member for preventing the weight member 2 from radially escaping is provided on the annular positioning groove 11.

The limit member has various embodiments, and the present embodiment adopts a structure with lower cost, that is, the outer ring edge of the annular metal ring is provided with a chamfer, and the wheel body 1 is filled in the chamfer area during injection molding to form the limit member. Because the wheel main body 1 is formed by injection molding, when the edge of the outer ring of the annular metal ring is provided with a chamfer, the chamfer area can be filled with fluid plastic raw materials, and a circle of annular limiting convex ring is naturally formed.

Of course, the stop member may be in other forms, such as a groove on the end surface of the annular metal ring, and the wheel body 1 is formed by filling the groove area during injection molding to form the stop member, so that the annular metal ring can be radially stopped.

For the specific structure of the wheel main body 1, in order to simplify the structure of the wheel main body 1, the wheel main body 1 includes a wheel outer ring 12, a wheel inner ring 13 and a plurality of radially arranged connecting strips 14, and two ends of the connecting strips 14 are respectively connected with the wheel outer ring 12 and the wheel inner ring 13. Such structural design for the structural strength of wheel main part 1 can be guaranteed, and the lightweight degree also makes better simultaneously.

In order to make the end face of the inertia wheel more flat, the inertia wheel further comprises at least one end cap 4, the end cap 4 being mounted on the end face of the wheel body 1. With such a design, the internal structure of the wheel body 1 can be designed to be hollow, for example, the wheel body outer ring 12 and the wheel body inner ring 13 can be designed to be more freely designed, and the end face can be shielded as long as the upper end cover 4 is covered, so that the appearance looks neater. The end cap 4 is detachably connected to the wheel body 1, preferably by a snap connection.

The end cover 4 is provided with a mounting groove 41, and a decoration block 42 is mounted in the mounting groove 41. There are many designs for the decoration blocks 42, and the decoration blocks 42 in this embodiment are designed in a radial shape uniformly distributed in a radial direction.

Because the center of the inertia wheel is generally connected with the driving shaft, in order to ensure that the connection between the inertia wheel and the driving shaft is more stable, the inertia wheel also comprises a central shaft body 5, the center of the wheel main body 1 is provided with a central shaft hole 15 matched with the central shaft body 5, and the wheel main body 1 and the central shaft body 5 are integrated through secondary injection molding. The central shaft body 5 is arranged, so that the strength of the wheel main body 1 in the central position can be enhanced, the wheel main body can be connected with a driving shaft more stably, and larger torque can be borne.

In order to further improve the connection stability between the wheel main body 1 and the center shaft body 5 and to prevent the relative rotational slip between the wheel main body 1 and the center shaft body 5, a plurality of fitting grooves are formed in the outer wall of the center shaft body 5, and a plurality of insert blocks 16 are respectively fitted in the fitting grooves in the wheel main body 1. So just form the structure similar to the spline between the two, simultaneously because form through the secondary injection moulding between wheel main part 1 and the central axis body 5, both are similar to the spline connection, but both do not need follow-up equipment, so both guarantee to connect stably, make the simplification installation step again.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
