Description

Technical Field

[0001] The utility model relates to the technical field of sun visors, in particular to an electric rolling curtain structure used for a mirror glass of a car sun visor. Background Art

[0002] Cars are generally equipped with a sun visor to block light. It is installed under the front crossbeam of the car's roof and behind the car's front windshield. When the driver is driving, it can prevent the glare of the sun from interfering with the driver and protect the driver's eyes.

[0003] The sun visor currently in use includes a frame body and a mirror glass fixedly installed on the frame body. In order to better reduce the dust adhering to the mirror glass, it is necessary to cover the mirror glass. Then, a roller blind capable of covering the mirror glass has emerged. The roller blind is rolled up by a motor, and when covering is needed, the roller blind is driven down by the gravity of the counterweight block. When the sun visor is in a tilted state, the gravity of the counterweight block is insufficient, and the roller blind cannot be driven down to cover the mirror glass, which cannot meet the use requirements. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide an electric roller blind structure for automobile sun visor mirror glass that can improve the retraction and extension stability of the roller blind and is simple, convenient and highly reliable.

When the mirror body needs to be used, the power structure drives the scroll to rotate, and the scroll winds the rolling curtain, then the mirror body can be used normally. After the mirror body is used, the power structure drives the scroll to rotate in the reverse direction, and drives the rolling curtain to reset through the reset structure to shield the mirror body.

[0010] The skeleton body and the mirror structure both belong to existing structures.

[0011] Among them, the power structure includes a servo motor fixedly installed inside the upper frame. The output shaft of the servo motor is fixedly connected to the scroll. Two supports are fixedly installed inside the upper frame. The scroll is rotatably connected to the supports. The servo motor is electrically connected to a circuit board installed inside the skeleton body. The circuit board is connected to a switch button, and the switch button is fixedly installed on the upper frame.

[0012] Among them, limiting disks are fixed at both ends of the scroll, and the rolling curtain is located between the two limiting disks.

[0013] Among them, the counterweight block is provided with a chute, and sliding rails that are slidably matched with the chute are fixed on both sides of the upper frame.

[0014] Among them, the cross section of the sliding rail is T-shaped.

[0015] Among them, the reset structure includes a wire winding disk. A pin shaft is fixed on the upper frame. The wire winding disk is coaxially and rotatably connected to the pin shaft. The wire winding disk is provided with a placement groove. A torsion spring is arranged in the placement groove. One end of the torsion spring is fixedly connected to the pin shaft, and the other end of the torsion spring is fixedly connected to the wire winding disk. The wire winding disk is fixedly connected to one end of a pull rope, and the other end of the pull rope is fixedly connected to the counterweight block.

[0016] Among them, a guide wheel for guiding the pull rope is rotatably installed inside the upper frame, and a guide ring groove is provided on the circumference of the guide wheel.

[0017] In summary, the electric rolling curtain structure for the automotive sun visor mirror glass of the present invention has the advantages of being able to improve the winding and unwinding stability of the rolling curtain, being simple and convenient, and having high reliability.
