Sun-shading equipment of vehicle

Abstract

The invention relates to a sunshade device for an automobile, wherein a first connecting rod and a second connecting rod which stretch or shrink a first arm unit and a second arm unit which are combined with a sunshade rod are actuated by a first rack and a second rack; the first rack and the second rack are meshed with a first driving pinion and a second driving pinion which are driven by a motor and perform rectilinear movement in opposite directions; further more, a torsional spring is matched above a corresponding pivot which combines upper arm members of the first arm unit and the secondarm unit to the sunshade rod, so that the torsional spring can accelerate stretch of various upper arm members. The torsional arm can be easily assembled into the device, does not generate vibration or noise, and has light weight, so that the power required for moving the sunshade rod up and down is reduced. Therefore, the invention realizes miniaturization of driving units and light weight of the sunshade device.

Description

Sunshade equipment for cars technical field The present invention relates generally to sunshade devices for automobiles, and more particularly to such a sunshade device for automobiles that is installed in the automobile near the rear window and that uses a motor to extend the sunshade screen from the reel out, thereby shading the interior of the car from sunlight. Background technique An electric sunshade device for an automobile is typically mounted on a rear shelf between a rear seat and a rear window in a passenger compartment of the automobile, and the rear shelf has low structural strength. Due to the low structural strength of the rear shelf, the motorized sun protection device must therefore be characterized in that it does not generate vibrations or vibrations when starting and stopping operation, is light in weight and generates low operating noise, and also requires high operating reliability. U.S. Patent No. 6,216,762 discloses a sunshade device in which a tu...
