2results about How to "Does not interfere with normal use" patented technology

The present application relates to the technical field of automobile steering wheel, and particularly relates to a quick folding multifunctional steering wheel, which comprises a hub and a rim, the side close to the rim of the hub is fixedly connected with a first turnover mechanism, the position close to the first turnover mechanism of the rim is fixedly connected with a second turnover mechanism, and the first turnover mechanism and the second turnover mechanism are rotationally connected with each other to connect the hub and the rim. The first turnover mechanism and the second turnover mechanism are arranged to enable the rim and the hub of the steering wheel to be relatively rotated, and when being manually rotated to a vertical state, more space can be provided for the driver. When being manually rotated to a horizontal state, the expansion structure provided is placed on the rim, including but not limited to providing a platform function for placing a water cup, reading and writing, to provide more comfortable and convenient functions for the driver. When not needed, the expansion structure is taken out from the rim, and the normal use of the steering wheel is not affected.

This invention relates to the field of audio equipment and discloses a multi-speaker anti-interference audio system, comprising an audio body and two loudspeakers installed within the audio body. Each of the two loudspeakers has a honeycomb panel at its front end and a gap-reducing assembly on its outer periphery. A dustproof and cover assembly is located on the side of the audio body near the loudspeakers. Each gap-reducing assembly includes an independent isolation chamber, one side of which is fixedly connected to one side of the honeycomb panel. The independent isolation chamber contains a sound-absorbing pad. By using an independent isolation chamber around the two loudspeakers, the sound-absorbing pad is housed within the isolation chamber and clamped to the rear of the honeycomb panel. Simultaneously, a guide rod within a ring-shaped rotating plate, in conjunction with a first spring on the outer periphery, drives a contact post to elastically abut against the sound-absorbing pad, achieving a clamping and elastic abutment-type gap reduction between the honeycomb panel and the sound-absorbing pad.
