The present application claims benefit of Chinese Patent Application No. 201810232961.3, filed on Mar. 21, 2018, the contents of which are hereby incorporated by reference in its entirety.
Automobiles have evolved into important products for people's daily lives. People are increasingly demanding automotive aesthetics while pursuing performance. As an important part of an automobile, the automobile hub is not only related to the driving safety and comfort of the automobile, but also has an important influence on the aesthetics of the entire vehicle. As an important safety part and appearance part of the automobile, the aluminum alloy hub plays an important role in good comprehensive performance of safety, aesthetics, recyclability and light weight (at least 30% of the weight reduced), especially wins the favor of the market in the attractive appearance, and has become the best choice for people.
However, as people's demands for the appearance and personalization of automobiles are increasing, it is hoped that the wheel disc surface of the wheel also has a better decorative and display function, thereby providing a better body appearance. At present, the wheel disc surface of the wheel is generally decorated by color or color register coating thereof. This method only can produce a static decorative effect on the wheel disc surface.

The shape of the eccentric weight is selected from the group consisting of a pear shape, an ellipse, a non-full cylinder or a rounded corner triangle. A decorative cover is mounted on the decorative cap and encloses the magnetic power generation portion and the battery inside the decorative cap. The hub for displaying dynamic images further includes a rotational speed detecting portion, the rotational speed detecting portion includes a rotational speed sensor, and the rotational speed sensor is in data connection with the circuit board. The rotational speed sensor is mounted on the decorative cap and connected to the FPC, and the rotational speed sensor is configured to transmit the detected rotational speed to the circuit board through the FPC. The hub for displaying dynamic images further includes a control portion which includes a memory and a processor. The memory stores imaging data, and the processor is configured to read the current speed of the automobile from the rotational speed sensor of the rotational speed detecting portion and analyze same, and control the turn-on time, frequency, strength and color of the beads of the LED light bars; and the magnetic power generation part is electrically connected with the dazzling imaging portion by a wire. The middle fastening portion of the decorative cap is an elastic tensioning mechanism.
During normal driving of the automobile, the hub drives the circuit board, the battery bushing and the magnetic coil to rotate; since the eccentric weight is a non-full cylinder, the center of gravity is lower, the eccentric weight, the strong magnet and the rotating shaft do not rotate under the co-action of the bearing system and the eccentric weight, the magnetic coil continuously cuts the magnetic lines to generate current, and power is supplied to the LED lights through the connecting wires. The hub and a brake disc are mounted on a load-bearing shaft of the automobile, and a brake drum can be frictionally engaged with the brake disc to brake the automobile. The battery is connected to the magnetic coil and the circuit board via connecting wires respectively. The battery supplies power to the LED lights when the rotational speed of the automobile is low; and the magnetic power generation portion supplies power to the LED lights during normal driving, and stores redundant power to the battery. The control system is mounted in the circuit board, the rotational speed sensor detects the rotational speed of the hub and transmits the detected data to the control system, and the control system controls the parameters such as color, strength and frequency of a series of LED lights mounted in the FPC via a pre-written program according to the rotational speed of the hub, so that the front of the hub presents different dynamic images. The principle of imaging is to calculate the change frequency of the LED lights by means of the rotational speed. It is supposed that the rotational speed of the hub is 60 rpm, that is, 60 revolutions per minute, and one revolution per second. A string of LED lights is arranged in the radial direction on the decorative cap of the hub. It is assumed to be 10 LED lights which are numbered from 1 to 10 from the axle center to the edge of the hub. Then it is assumed that the LED lights are 0 degrees just above the hub at 0 second; if the effect of 6:00 is desired to be displayed on the hub, No. 1-10 lights are lightened at 0 second to display the minute hand, No. 1-5 lights are lightened at 0.5 second to display the hour hand, then No. 1-10 lights are lightened at 1 second to display the minute hand, No. 1-5 lights are lightened at 1.5 second to display the hour hand, and so on. Thus, a complete 6:00 full-clock image will be displayed through visual persistence of human eyes. Complex patterns are also deduced by analogy, as long as 3 points are accurately calculated: 1, initial phase of the LED lights; 2, rotational speed of the hub 1; and 3, current time. It is possible to know the positions of the LED lights at certain moment. As long as the different LED lights are lightened at different positions, a complete pattern can be finally formed. As the number of the LED lights increases, the image effect is clearer.
The shape of the eccentric weight of the magnetic power generation portion can be selected from various structures, and three kinds are listed in the present disclosure and compared by experiments. The comparison method is to mount the eccentric weights of the three structures on a tester respectively, and detect the rotational speed of the wheel when the eccentric weights deflect 30 degrees. The test data and results are shown in Table 1.
It can be seen from the above table that the pear-shaped structure in the A scheme is optimal.
