Tire with self-generation, sound absorption, and electronic unit
A recently granted patent (Publication Number: US11993107B2) discloses a tire design that incorporates self-generation and sound absorption features. The tire includes a wall structure attached to the inner liner, a sound absorber positioned above the inner liner to block sound from treads and road surfaces, and an electronic unit between the inner liner and the sound absorber. The wall structure consists of bodies with insertion grooves for the sound absorber, which can be made of a porous sponge material to enhance sound absorption capabilities. Additionally, the wall structure may contain wires for generating electrical energy through frictional electrification with the porous sponge material.
Furthermore, the tire design includes an electronic unit with sensors for monitoring tire conditions and a power module for supplying power. The sound absorber is made of a polymer film with couplers at both ends for attachment to the wall structure, and wires within the couplers for generating electrical energy through frictional electrification. The design also features specific thickness variations in the sound absorber at different sections for optimized performance. Overall, this patented tire design aims to provide improved sound absorption capabilities while also incorporating self-generation features for enhanced functionality and performance on the road.
