Abstract: A rotary imaging device for wheels and an automobile are disclosed. The rotary imaging device for wheels includes a housing matched with the wheels, and a processing component, a display component and a power supply that are installed in the housing, the processing component being electrically connected with the display component and the processing component and the display component being both electrically connected with the power supply. The processing component is configured to send received or read to-be-displayed content to the display component after preset processing, and the display component is configured to display the to-be-displayed content sent by the processing component. According to the rotary imaging device for wheels and the automobile, images or videos can be formed through rotation of the wheels.

Abstract: The present disclosure relates to a sound absorber and a wheel having the same. The sound absorber is configured as a rectangular hexahedral box and forms a porous double-layer Helmholtz resonance sound absorbing structure, at the same time, the sound absorber in the form of a box forms a structural resonance sound absorbing device itself, and the first-order natural mode frequency of the device is identical to that of a wheel air chamber. When the box-type sound absorbing structure is assembled in a wheel, double functions of absorbing acoustic resonance of the wheel air chamber under the organic combination of Helmholtz resonance sound absorption and structural resonance sound absorption can be realized.
