AI Technical Summary

Technical Problem

The existing vehicle flow tank drains lack sound insulation, causing tire noise to be transmitted into the cab through the drain, reducing the NVH value and ride comfort of the entire vehicle.

Method used

A sound insulation device for drain outlet of a vehicle flow tank is designed, including a sealing component, an actuating component and a control component. The sealing component is fixed to the drain outlet position of the flow tank through clamping. The outer ring is equipped with a recessed drainage area and water inlet, and a flow channel and solenoid valve are installed inside. The water sensor senses the water level changes and controls the solenoid valve to open or close, so as to achieve water discharge and seal.

Benefits of technology

Effectively reduce tire noise, improve sound insulation, reduce the NVH value of the entire vehicle, and improve the comfort of the cab.

Abstract

The invention belongs to the technical field of automobile parts, and relates to a sound insulation device for a drainage outlet of an automobile gutter channel. The invention further relates to a sound insulation method of the sound insulation device for the drainage outlet of the automobile gutter channel. The sealing component (A) is fixedly installed at the position of a water outlet (1) of a gutter channel, a drainage area (2) is arranged on the outer ring of the sealing component (A), a water inlet (3) is formed in the drainage area (2), the sealing component (A) is fixedly connected with a framework (5) of the execution component (B), an electromagnetic valve (6) in the framework (5) extends to the position of a water flowing channel (4), and the height position of the electromagnetic valve (6) is lower than that of the water inlet (3). According to the sound insulation device and method for the drainage port of the automobile gutter channel, the drainage port of the gutter channel can be sealed while it is ensured that water gathered in the gutter channel is reliably drained, the tire noise of tires is effectively reduced, the sound insulation effect is improved, and therefore the NVH value of the whole automobile is effectively reduced, and the comfort of a cab is improved.
