Connecting rod rocker arm mechanism for air door of automobile air handling unit

Abstract

The invention discloses a connecting rod rocker arm mechanism for an air door of an automobile air handling unit. The connecting rod rocker arm mechanism comprises a rotatable connecting rod and a rocker arm arranged on the air door of the automobile air handling unit, wherein the connecting rod is provided with track grooves; the rocker arm is provided with swing posts capable of moving in the track grooves; the rocker arm is used for driving the connecting rod to rotate through the swing posts while rotating; the connecting rod is provided with a left track groove and a right track groove; the rocker arm is correspondingly provided with a swing post I moving in the left track groove and a swing post II moving in the right track groove; when the swing post I and the swing post II move in the left and right track grooves, the swing posts which are far away from the rotating center of the connecting rod are used for driving the connecting rod to rotate. By adopting the connecting rod rocker arm mechanism, the air door rotation control accuracy is increased, and the shaking degree of a hybrid air door is lowered.

Description

technical field [0001] The invention belongs to the field of a transmission mechanism for an air door of an automobile air-conditioning box, and in particular relates to a double-track link rocker mechanism. Background technique [0002] The transmission mechanism of the automobile air-conditioning box damper in the prior art is as figure 1 The shown includes the connecting rod and the rocker arm, wherein the connecting rod is provided with a track groove, and the rocker arm is provided with a rocker column, and the rocker column on the rocker arm moves in the track groove in the connecting rod, and the rocker arm turns from the left to the middle position Then turn to the right in these two processes so that the same trajectory is used twice in one trip. Disadvantages: 1. Adjust the linearity of the temperature rise of the air-conditioning box by adjusting the opening of the mixing damper of the air-conditioning box. It is difficult to control the opening of the damper by ...

AI Technical Summary

Problems solved by technology

Disadvantages: 1. Adjust the linearity of the temperature rise of the air-conditioning box by adjusting the opening of the mixing damper of the air-conditioning box. It is not easy to control the opening of the damper by using the same track back and forth; 2. When the rocker arm and the connecting rod are in the collinear position, the whole mechanism is easy In addition, due to the existence of production errors, the vibration of the damper at this position will increase
