Description

Rocker arm trajectory compensation mechanism for electric side window sunshade

The present invention relates to an electric side window sunshade for a motor vehicle, especially the electric side window sunshade, which assists the driving of the cloth curtain to unfold and expand, so that the unfolded cloth curtain can extend the triangle covering the rear end of the side window of the motor vehicle. The rocking arm movement trajectory compensation mechanism of the window part.

At present, a laterally moving electric side window sunshade applied to a rear side window of a motor vehicle is mainly fixed to a front side position of a side window glass by a cloth curtain base having a cloth curtain retractor, and is further installed on a side door. The electric motor unit in the drive can pull the curtain connected to the curtain retractor to expand and close by the swing arm that moves linearly along the lateral guide rail.

The shape of the side window of the rear side door of a general motor vehicle is provided with a triangular window portion on the rear side of the side window of the rear side door in order to match the design of the body shape of the motor vehicle. Therefore, in order to achieve a better performance in shielding sunlight, the cloth curtain of the laterally moving electric side window sunshade must cover the rear side window itself and the triangular window portion on the rear side as much as possible. However, in the existing structure of the laterally-moving electric side window sunshade, the lateral guide grooves of the lateral guide rail are used to guide the rocker arm connected to the edge panel of the curtain to move along the horizontal straight line. Due to the length of the lateral guide rail due to the limitation of the side door The rear end of the lateral guide rail cannot extend below the triangular window portion, and the motion trajectory of the rocker arm that pulls the curtain moves is a horizontal straight line pattern, so the curtain cannot completely cover the triangular window portion after deployment, affecting its performance of shielding the sun .

The purpose of the present invention is to provide a rocking arm movement trajectory compensation mechanism for an electric side window sunshade, which solves the problem that the cloth curtain of the existing electric side window sunshade is difficult to completely cover the triangular window portion at the rear end of the side window.

In order to achieve the foregoing object, the rocker arm movement trajectory compensation mechanism of the electric side window sunshade provided by the present invention is a rocker arm for connecting an electric drive assembly of an electric side window sunshade, and a pivot joint at the lower end of the rocker arm The electric side window sunshade is provided with a driving block capable of moving along a lateral guide rail.
