[0003] For example, the utility model with application number CN202021464062.5 discloses an electrically controlled automatic sunshade for a front windshield and a car. The utility model drives the sunshade to move to the sunshade position by an executive motor. Compared with the mechanical flip-up solution of manually pulling the sun visor in the prior art, the opening operation of the sunshade in this solution is more convenient, which is conducive to ensuring safety during driving. However, in the actual use of such devices, since the front windshield is relatively wide, the traction rod needs to move more positions during the opening or winding process, which affects the opening and closing time of the sunshade. At the same time, when winding, due to the excessive winding of the sunshade on the outside of the reel, the radius of the wound sunshade is too large, and the overall space is occupied.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a car sunshade with electric control is provided. Utility Model Content

[0012] Furthermore, the guide plate is U-shaped, and the guide plate fits the roller.

[0013] Furthermore, the width of the guide groove is equal to the width of the counterweight block, and the guide groove is rectangular.

[0014] The utility model provides an electric-controlled automobile sunshade, which has the following beneficial effects:

[0015] 1. The utility model can make the winding shaft reel in the rolling curtain by setting the control component, and the servo motor drives the driven gear to rotate through the reducer and the driving gear, and when the output shaft of the servo motor rotates in the opposite direction, the bottom plate will pull the rolling curtain under the action of gravity, so when the winding shaft unwinds, the rolling curtain will automatically unfold, so as to cover the front windshield of the car. Compared with horizontal rewinding, the vertical rewinding method can reduce the rewinding distance, thereby reducing the waiting time. At the same time, after rewinding, the rolling curtain will be located at the top of the car, and will not affect the driver's observation of the road condition due to its large volume on both sides of the car, which is safer. The servo motor, reducer, driving gear, driven gear, and rewinding shaft form a U-shaped structure, which makes the whole more compact and reduces the space occupied.

[0016] 2. The utility model provides a guide assembly. When the base plate moves downward under the action of gravity, the guide plate and the counterweight block can be used to guide the moving direction of the base plate, so that the roller blind can adapt to the inclined windshield. At the same time, the friction loss between the guide plate and the counterweight block can be reduced by the roller to avoid jamming during movement, thereby improving the smoothness during use.
