TECHNICAL FIELD

[0001] The present application relates to automobile parts, in particular to a wheel hub centrifugal decoration device. BACKGROUND

[0002] The automobile wheel hub decoration cover is mainly used for external decoration of the wheel hub, so that the rotating line of the wheel hub during the driving of the automobile is more beautiful. The existing wheel hub large disc decoration cover is generally a plastic injection molded body. For example, a wheel hub decoration cover disclosed in Chinese Patent Publication No. CN211441839U includes a large disc and a mounting bracket. The large disc is fixed on the wheel hub through the mounting bracket. The mounting bracket includes a connecting plate, connecting arms arranged on both sides of the connecting plate, and connecting ears arranged at the lower ends of the connecting arms. The connecting plate is provided with a first mounting hole. The large disc is connected with the first mounting hole of the connecting plate through a bolt. The connecting ears are provided with second mounting holes. The connecting ears are connected with the wheel hub through a bolt. This kind of decoration cover does not have a changing effect. It is necessary to design a device capable of changing the shape of the decoration part through centrifugal force. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a wheel hub centrifugal decoration device capable of realizing lifting change through centrifugal force, changing the shape of the decoration device, and helping to reduce the wind resistance of the decoration device when the wheel hub rotates at high speed.

[0004] To solve the above technical problems, the present invention provides a centrifugal decoration device for a wheel hub, comprising a reset mechanism, a plurality of inserts distributed circumferentially around the reset mechanism, a strip disposed between adjacent inserts, and a centrifugal mechanism disposed below each insert; the side surfaces of the inserts are connected to the strip; the reset mechanism comprises a base fixed to the center of the wheel hub and an upper cover disposed above the base; the base is provided with a plurality of guide rods distributed circumferentially; the upper cover is provided with guide holes for the guide rods to extend; a plate fixed to the guide rods is disposed above the upper cover; a spring is disposed between the base and the upper cover and is sleeved on the guide rods; a support platform is disposed at the lower end of the guide rod; one end of the spring is fixed to the support platform; and the upper end of the spring is connected to the upper cover; the centrifugal mechanism comprises a limiter fixed to the bottom of the insert, a hinge seat fixed to the wheel hub, a rocker, and a roller; one end of the rocker is hinged to the hinge seat; the roller is pivotally connected to the other end of the rocker; the limiter is provided with a limit slot, and the roller is disposed within the limit slot. The principle of the present invention is as follows: when the centrifugal mechanism is in a low-speed rotation state, the centrifugal force is not enough to drive the pendulum rod, the pendulum rod sticks to the wheel hub, the insert is in the lowest position, and the upper cover is in the lowest position. At this time, the insert is basically in an inwardly tilted state; when the centrifugal mechanism is in a high-speed rotation state, the pendulum rod swings upward under the influence of centrifugal force, and the pendulum rod uses the roller to push the corresponding insert upward. The angle of the pendulum rod changes with the speed of the wheel hub. When the wheel hub speed reaches the preset speed, the swing angle of the pendulum rod is the largest, the insert is in the highest position, and the upper cover is in the highest position. At this time, the outer end of the insert is basically flush with the inner end, and the wind resistance is minimized; when the wheel hub speed decreases, the upper cover decreases under the action of the spring, the upper cover drives the inlay strip, and the inlay strip drives the inlay strip.

[0005] As an improvement, the base is provided with a mounting hole corresponding to the guide rod, the guide rod includes a threaded section, a support platform and a light rod section, the spring is sleeved on the light rod section, the threaded section passes through the mounting hole and is threadedly connected to the wheel hub, and the support platform presses the base onto the wheel hub.

[0007] As an improvement, an annular protrusion is provided at the bottom of the upper cover corresponding to the guide hole, and the upper end of the spring is arranged in a receiving groove formed by the annular protrusion.

[0008] As an improvement, one end of the inlay is hinged to the upper cover, and the other end of the inlay is hinged to the outer side of the wheel hub.

[0009] As an improvement, the insert is fan-shaped.

[0010] As an improvement, the limiting member and the insert are connected via a snap fastener.

[0011] As an improvement, the articulated seat is connected to the wheel hub via bolts.

[0012] As an improvement, the roller is a bearing.

[0013] The beneficial effects brought about by the present invention compared with the prior art are:

[0014] The centrifugal lifting mechanism is applied on the wheel hub. The centrifugal force is transmitted to the centrifugal mechanism through the rotation of the wheel hub. The centrifugal mechanism can drive the inserts on the wheel hub, thereby changing the shape of the inserts. At high speed, each insert is basically in a plane, which helps to reduce the wind resistance of the inserts. BRIEF DESCRIPTION OF THE DRAWINGS

The slat 3 comprises a plastic body and a metal rod disposed within the body. One end of the metal rod is hinged to the reset mechanism 4, and the other end is hinged to the outside of the wheel hub 1. The outer end of the slat 3 is fixed, while the inner end of the slat 3 rises and falls according to the centrifugal force. The sides of the inserts 2 are connected to the plastic body via snaps, and the slat 3 and inserts 2 are linked.
