DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0020] Referring to FIG. 1, a wheel cover unit A in accordance with a preferred embodiment of the present invention can be assembled to a wheel rim C of a front wheel B of a truck or bus as shown in FIG. 2, the wheel rim C has an inner concave surface C1 (as shown in FIG. 5) and an outer convex surface C2 located on an outer side of the wheel rim C. The wheel rim C is defined with an intermediate hole C3 and a plurality of perforating holes C4 on the outer convex surface C2, and between the intermediate hole C3 and the perforating holes C4 is annularly assembled a plurality of bolts C5. The wheel cover unit A includes a wheel cover 1, two bearing members 2 and a cover 3.

[0021] The wheel cover 1 is provided with an outer convex platform 11 having a central hole 12 in the center thereof, and the periphery of the central hole 12 is annularly provided with a plurality of nut convex covers 13. In a periphery of the outer convex platform 11 is defined a plurality of through holes 14, each through hole 14 is backwardly provided with a protruding seat 141 at the inner edge thereof (as shown in FIGS. 3-4), such that when the wheel cover 1 is assembled to the wheel rim C, the protruding seats 141 can be assembled into the perforating holes C4 of the wheel rim C (as shown in FIG. 5). In addition, the inner edge of the central hole 12 is vertically and backwardly provided with a hole ring 15 having corresponding two pairs of slots 151 (as shown in FIG. 3), and each slot 151 extends to the central hole 12 with a lock sheet 16. Viewed from the external side, the lock sheet 16 is lower than the edge of the central hole 12 (as shown in FIGS. 5-6) and is vertical to the hole ring 15. Moreover, on the inner side of the outer convex platform 11 is protruded with a plurality of ribs 17 that are located between the nut convex covers 13 (as shown in FIG. 3), the ribs 17 also can increase the structural strength of the wheel cover 1 and reduce the thickness of the wheel cover 1, saving the material cost.

[0022] Referring to FIG. 2, each bearing member 2 is provided with a connecting portion 21 and two connecting pieces 22. The connecting portion 21 is defined with a penetrating hole 211 for passing through the bolt C5 of the wheel rim C, the connecting piece 22 is locked with the lock sheet 16 via a screwed element 23, so as to assemble the wheel cover 1 to the wheel rim C. The connecting piece 22 is lower than the connecting portion 21 and is engaged in the slot 151 of the hole ring 15. When the connecting piece 22 is locked with the lock sheet 16 via the screwed element 23, there is a distance G between the connecting piece 22 and the lock sheet 16 (as shown in FIG. 6), so that the locking tightness can be increased when the screwed element 23 is used.

[0023] Referring to FIGS. 2-3, a cover ring 31 is backwardly extended from the cover 3 and is defined with a slot 311 corresponding to the lock sheet 16 of the wheel cover 1, so that the cover 3 can be engaged in the central hole 12 of the wheel cover 1. Also, the cover ring 31 of the hole cover 3 is provided with an engaging portion 32 on the bottom side thereof. When the cover 3 is engaged in the central hole 12, the engaging portion 32 is engaged in the hole ring 15 (as shown in FIG. 6). The cover ring 31 of the cover 3 also has a plurality of grooves 312, which makes the cover ring 31 have an appropriate elastic margin for engaging in the central hole 12.

[0024] In operation, the wheel cover unit A is firstly locked with the C5 of the wheel rim C of the front wheel B by the connecting portion 21 of the bearing member 2 (as shown in FIGS. 5-6), and then the central hole 12 of the wheel cover 1 is aligned to the intermediate hole C3 of the wheel rim C and the lock sheet 16 is aligned to the connecting piece 22. At that time, since the connecting piece 22 is engaged in the slot 151 of the hole ring 15, and the protruding seat 141 of the wheel cover 1 is fitted in the perforating hole C4 of the wheel rim C, the lock sheet 16 can be locked with the connecting piece 22 via the screwed element 23. In addition, due to the distance G between the connecting piece 22 and the lock sheet 16, the locking tightness can be increased when the screwed element 23 is used, which can avoid the movement and the shedding of the wheel cover 1 when driving or the brake stops. Finally, the cover 3 is engaged in the central hole 12, and the engaging portion 32 is engaged in the hole ring 15.

[0025] It can be seen from the above structure that main idea of the invention lies in: the lock sheets 16 are added at the central holes 12 of the wheel cover 1, and by the connection of the bearing member 2, the wheel cover 1 can be locked to the wheel rim C of the front wheel B, and the larger ring cover 1 can also be applied to the front wheel B of a large truck or bus, so that the practicability of the invention is higher. Moreover, the wheel cover 1 and the cover 3 are plastic injection molding, which is light and strong, and more three-dimensional.

[0026] While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
