Description

Technical Field

[0001] The utility model relates to the technical field of sun visors, in particular to a rolling curtain device 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 a rolling curtain device for automobile sun visor mirror glass that can improve the retraction and extension stability of the rolling curtain and is simple, convenient and highly reliable.

[0007] A rolling shutter groove is formed between the mounting frame and the upper frame, a rolling shutter is arranged in the rolling shutter groove, one end of the rolling shutter is fixedly connected to a reel, both ends of the reel are connected to the upper frame via a winding structure, both sides of the other end of the reel pass through the mounting frame and are fixed with connecting rods, and the connecting rods are connected to the electric drive structure.

[0008] In this way, the rolling curtain is set in the rolling curtain groove, which is located between the mirror body and the upper frame. When the mirror body needs to be used, the rolling structure drives the reel to rotate, and the reel winds the rolling curtain to expose the mirror body. After the mirror body is used, the electric drive structure drives the connecting rod to move, and then drives the rolling curtain to reset and cover the mirror body.

[0009] The skeleton body and the mirror structure both belong to existing structures.

[0010] Among them, the winding structure includes a support fixed on the upper skeleton, a sleeve fixed to the support, a reel inserted into the sleeve, and both ends of the reel and the sleeve are fixedly connected to both ends of a torsion spring.

[0011] Among them, limiting disks are fixed at both ends of the reel, and the rolling curtain is located between the two limiting disks.

[0012] Among them, the electric drive structure includes a motor bracket fixed on the upper skeleton, a servo motor fixed on the motor bracket, a rotating shaft fixed to the output shaft of the servo motor, two winding disks fixed on the rotating shaft, one end of a pulling rope is fixedly connected to the winding disk, and the other end of the pulling rope is fixedly connected to a connecting rod.

In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the protection scope of the present utility model; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0029] Embodiment:

[0030] As Figures 1-12 shown, a rolling curtain device for an automotive sun visor mirror glass includes a skeleton body and a mirror glass 1. The skeleton body includes an upper skeleton 2 and a lower skeleton 3 which are snap-connected. The mirror glass is located between the upper skeleton and the lower skeleton. The upper skeleton is provided with a relief area 4 facing the mirror glass. An installation frame 5 is bonded to the inner side of the upper skeleton. The installation frame is arranged outside the relief area. The mirror glass is bonded to the installation frame;

[0031] A rolling curtain groove is formed between the installation frame and the upper skeleton. A rolling curtain 6 is arranged in the rolling curtain groove. One end of the rolling curtain is fixedly connected to a reel 7. Both ends of the reel are connected to the upper skeleton through a winding structure. The two sides of the other end of the reel pass through the installation frame and are fixed with a connecting rod 8. The connecting rod is connected to an electric drive structure.

[0032] In this way, the rolling curtain is arranged in the rolling curtain slot, which is located between the mirror body and the upper skeleton. When the mirror body needs to be used, the winding structure drives the reel to rotate, and the reel winds the rolling curtain to expose the mirror body; after the mirror body is used up, the electric drive structure drives the connecting rod to move, and then drives the rolling curtain to reset to cover the mirror body.

[0033] The skeleton body and the mirror structure both belong to existing structures.

[0034] During implementation, the winding structure includes a support 11 fixedly installed on the upper skeleton. A sleeve 12 is fixed to the support. The reel is inserted into the sleeve, and the reel and the sleeve are respectively fixedly connected to both ends of a torsion spring. Through the setting of the torsion spring, the reel has a force to wind the rolling curtain.

[0035] During implementation, limit discs 13 are fixed to both ends of the reel, and the rolling curtain is located between the two limit discs. This facilitates the limitation of the wound rolling curtain.

[0036] During implementation, the electric drive structure includes a motor bracket fixedly installed on the upper skeleton. A servo motor 14 is fixed to the motor bracket. A rotating shaft 15 is fixed to the output shaft of the servo motor. Two wire winding discs 16 are fixed to the rotating shaft. One end of a pull rope 17 is fixedly connected to the wire winding disc, and the other end of the pull rope is fixedly connected to the connecting rod. The servo motor drives the rotating shaft to rotate, thereby realizing the winding and relaxation of the pull rope. When the mirror body needs to be used, the servo motor drives the rotating shaft and the wire winding disc to rotate to relax the pull rope; conversely, after the mirror body is used up, the servo motor drives the rotating shaft and the wire winding disc to rotate in the reverse direction to wind the pull rope.

[0037] Of course, wire guiding wheels are rotatably arranged on the inner side of the upper skeleton corresponding to the wire winding discs to better deflect the pull rope.

[0038] During implementation, two supports 18 are fixed to the upper skeleton, and the rotating shaft is connected to the support through a bearing. This better supports the rotating shaft.

[0039] During implementation, a support seat 19 is also fixed to the upper skeleton. The support seat is located between the two supports, and the rotating shaft is connected to the support seat through a bearing. This improves the stability of the rotating shaft.

[0040] Specifically, a PCB board is fixed inside the skeleton body, and the switch button and the servo motor are both electrically connected to the PCB board.

[0041] Embodiment 1:

[0042] As Figures 3-8 , the rolling curtain is wound in the vertical direction.

[0043] Embodiment 2:

[0044] As Figures 9-12 , the rolling curtain is wound horizontally.

[0045] Specifically, a PCB board is fixed inside the framework body, and both the switch button and the servo motor are electrically connected to the PCB board.

[0046] Finally, it should be noted that those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. In this way, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalents, then the present utility model also intends to include these modifications and variations.
