Problems solved by technology
[0013] When the up-and-down distance of the second fender member 4 is relatively short, the fixed rod is hardly adopted due to the problem that the actuating rod 3 collides with the bracket 14.
[0015] The current technology is that the up and down distance of the second fender member is short, if a rotary rod type actuating rod is used, as figure 2 As shown, when the actuating rod moves from state ① to state ②, the position of the actuating rod changes in the downward bending state. In this state, when the actuating rod moves downward to state ③, the strike The problem that the action sound becomes louder due to the lower bracket

The present invention provides a noise reducing type airvent which comprises the following components: a first fender component which is equipped in pipeline and can move vertically; a fender button which is equipped on the first fender component, can slide and is provided with an actuating rod at the back part; a second fender component which is provided with a hinge shaft for insertion of the actuating rod on an upper bracket and a lower bracket and moves in the left-and-right direction through left-and-right sliding of the fender button; and a spacing block which is equipped on the bracket for preventing simultaneous contact between the actuating rods and the bracket in vertical movement.
Description
technical field [0001] The invention relates to a sound-attenuating air hole, specifically, there is a limit block on the bracket supporting the rotation shaft of the fender, which is used to prevent the actuating rod from directly hitting the bracket to reduce the sound-attenuating air hole of the action sound. Background technique [0002] Vehicle interiors generally have vents for hot and cold air. The air duct outlet portion of the vent engages a fender member that adjusts the air up and down, with the cover securing the fender to the duct. [0003] figure 1 is a traditional vent oblique view, figure 2 It is a state diagram of the up and down movement of the actuating rod of the fender in the traditional air vent. [0004] The traditional fender member 2 generally includes a first fender member 6 arranged horizontally at the outlet of the duct, together with the fender knob 1, to adjust the air supply direction up and down, vertically arranged at the outlet of the du...
