[0055] Optionally, the counterweight portion 7 and the base plate portion 311 may also be designed to be detachable, so that the counterweight portion 7 can be flexibly replaced.

[0056] In some embodiments, the counterweight portion 7 may not be additionally provided, and the vehicle logo base 31 may be divided into zones and injection molded using materials of different weights, so that the upper portion of the vehicle logo base 31 is lighter and the lower portion is heavier.

[0057] See also Figure 6 to Figure 7 and Fig.11 As shown, the mounting base 8 has a plurality of first buckles 84 extending from the main body 81 , the first buckles 84 being used to buckle and fix with the second buckles 101 on the wheel 10 , and the plurality of first buckles 84 enclose a limiting space.

[0058] See also Fig. 9 As shown, the wheel decorative cover also includes an elastic member 9, which is located in the limited space and fixed to the first buckle 84, and the elastic member 9 pushes against the first buckle 84 toward the outside of the limited space. The elastic member 9 provides a force toward the outside of the limited space for the first buckle 84, thereby improving the stability of the first buckle 84 and the second buckle 101 after being buckled, and improving the stability of the fixation between the wheel decorative cover and the wheel 10.

[0059] Optionally, there are multiple first buckles 84, and the elastic member 9 is a wire ring having multiple protrusions protruding toward the outside of the limiting space.

[0060] In some embodiments, a groove 841 is provided on the first buckle 84, and the wire ring is received in the groove 841. The wire ring generates a resisting force toward the outside of the limiting space to prevent the first buckle 84 from loosening after being installed with the wheel 10.

[0061] In some embodiments, the number of the first buckles 84 can be determined according to installation requirements, and the number of the protrusions of the elastic member 9 is the same as the number of the first buckles 84 .

[0062] In some embodiments, the elastic member 9 may be made of materials such as a wire ring, rubber, silicone or some polymers to achieve the function of fastening the first buckle 84 and the second buckle 101 of the wheel 10 .
