Abstract

The invention discloses a sound insulation cushion which comprises an upper load-supporting seat, an elastic body, fiber cotton batting and a lower load-supporting seat and takes the fiber cotton batting and the elastic body as a sound insulation cushion body. A load-supporting spring on a vehicle transfers load to the upper load-supporting seat, the upper load-supporting seat divides the load into two paths and transfers the load, one path of the load is transferred to the elastic body, the other path of the load is transferred to the fiber cotton batting, and the lower load-supporting seat receives the load transferred from the elastic body and the fiber cotton batting. According to the sound insulation cushion, the elastic body and the fiber cotton batting parallelly bear all load force. The elastic body shares part of the load force, the fiber cotton batting no longer deforms when the load force shared by the elastic body and load force for continuing deformation of the fiber cotton batting are balanced, so that the whole sound insulation cushion can bear large load force and can also effectively function in sound insulation and cushioning.

Description

technical field [0001] The invention relates to a sound-insulating and shock-absorbing pad, in particular to a sound-insulating and shock-absorbing pad for a vehicle. Background technique [0002] The existing sound-proof and shock-absorbing pads with a certain load-bearing capacity are basically directly placed on or under the spring by rubber. This method has the disadvantages of poor sound-proof and shock-absorbing effect and easy failure. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings in the prior art, the present invention provides a load-bearing sound-insulating and shock-absorbing pad, which is durable and has good sound-insulating and shock-absorbing effects. [0004] The technical solution adopted in the present invention is: a sound-insulating and shock-absorbing pad composed of an upper bearing seat, an elastic body, fiber batting, and a lower bearing seat, with fiber cotton and elastic body as the main body of sound ins...
