A 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.

Sound absorber and wheel having same

The present application relates to a wheel with a sound absorber, the sound absorber being mounted in a wheel air chamber to reduce acoustic resonance, wherein the sound absorber is configured as a flat hexahedral box resonator and fastened to a wheel hub through a band, a first positioning mechanism is provided between the hub and the box resonator to fix the relative positions of the hub and the box resonator, and a second positioning mechanism is provided between the box resonator and the band to fix the relative positions of the box resonator and the band. According to the technical solution of the present disclosure, the resonator is positioned and fixed more reliably on the wheel, and the wheel is simple and economical in manufacturing, and convenient and controllable in installation and operation.

Wheel with sound absorber

The present application provides a wheel rotation imaging device and a wheel rotation imaging intelligent advertising system. In the wheel rotation imaging device, power can be supplied by means of rotation of a wheel with the use of a self-powered unit, so an external power supply is not required; texts, images and videos can be displayed; in addition, a variety of sensors are integrated to acquire operation information of the device in real time, which facilitates the wheel rotation imaging device to adjust the imaging angle and brightness.

Wheel rotation imaging device and wheel rotation imaging intelligent advertising system

A display method for a wheel rotation imaging device includes: acquiring operation information, the operation information comprising ambient light intensity, wheel speed, vehicle acceleration, current time, current location, and current power; identifying a situational mode of vehicle driving according to the operation information, the situational mode being in one-to-one correspondence with a power consumption mode; and selecting a power consumption mode of the wheel rotation imaging device according to the situational mode, so that the wheel rotation imaging device completes display according to the power consumption mode. The wheel rotation imaging device is mounted on a wheel and can display texts, images or videos as the wheel rotates.
