[0033] See also Figure 1 , Figure 8 , Fig. 9 , Fig.10The full-mirror automobile sun visor with a rolling curtain described in the present invention, its retractor 8 includes a rotating sleeve 8-1, a first fixed shaft 8-3, a first fixed shaft seat 8-2, a compression spring 8-5, a sleeve connecting seat 8-6, a winding spring 8-7, a second fixed shaft 8-8 and a second fixed shaft seat 8-9; the first fixed shaft seat 8-2 and the second fixed shaft seat 8-9 are embedded at both ends of the rotating sleeve 8-1, and the three form an integrated structure; the first fixed shaft 8-3 and the first fixed shaft seat 8-2 are assembled in a clearance fit manner, and the outer end of the first fixed shaft 8-3 is tightly fixed to the side wall of one end of the rolling curtain box 7; the second fixed shaft 8-8 and the second fixed shaft seat 8-9 are assembled in a clearance fit manner, and the outer end of the second fixed shaft 8-8 is tightly fixed to the side wall of the other end of the rolling curtain box 7; the The compression spring 8-5, the sleeve connecting seat 8-6 and the winding spring 8-7 are all arranged inside the rotating sleeve 8-1, and the compression spring 8-5 is located between the first fixed shaft 8-3 and the sleeve connecting seat 8-6. The first fixed shaft 8-3 and the outer end are pressed against the side wall of one end of the rolling box 7 by the compression spring 8-5. A spring baffle 8-4 is provided at the outer end of the compression spring 8-5, and a flange baffle 8-3-1 is provided at the inner end of the first fixed shaft 8-3. Lubricating grease is applied to the contact surface between the spring baffle 8-4 and the flange baffle 8-3-1 at the inner end of the first fixed shaft 8-3; the sleeve connecting seat 8-6 is fixedly connected to the rotating sleeve 8-1 as a whole; one end of the winding spring 8-7 is fixed on the sleeve connecting seat 8-6, and the other end is fixed on the second fixed shaft 8-8.

[0034] See also Figure 1 , Figure 8 , Fig. 9 , Fig.10The full-mirror automobile sun visor with a rolling curtain described in the present invention has a working principle of the retractor 8 as follows: when the mirror effect of the sun visor is not needed, the curtain 4 can be pulled down by the curtain pull bar 10 at the end edge of the curtain 4, and then the clamping foot 10-2 on the curtain pull bar 10 cooperates with the lower frame of the frame 1 to fix the curtain 4 to block the LED light source and the light reflecting film. During this process, the rotating sleeve 8-1 rotates under the drive of the curtain 4, and drives one end of the winding spring 8-7 to rotate through the sleeve connecting seat 8-6 fixedly connected to the rotating sleeve 8-1. The other end of the winding spring 8-7 is fixed on the second fixed shaft 8-9, and the winding spring 8-7 produces elastic deformation and stores energy; when the mirror effect of the sun visor is required, the clamping foot 10-2 on the roller blind pull strip 10 is separated from the lower frame of the frame 1, and the pulling force of the curtain 4 on the rotating sleeve 8-1 is released. At this time, the winding spring 8-7 returns to its initial state and releases energy. The winding spring 8-7 drives the sleeve connecting seat 8-6 and the rotating sleeve 8-1 to rotate in the opposite direction, and the curtain 4 is wound around the rotating sleeve 8-1, thereby releasing the shielding effect on the LED light source and the light reflecting film. During the operation of the reel 8, the sleeve connecting seat 8-6 drives the spring baffle 8-4 to rotate through the compression spring 8-5, so that the spring baffle 8-4 and the flange baffle 8-3-1 at the inner end of the first fixed shaft 8-3 rotate relative to each other. In order to reduce the friction between the spring baffle 8-4 and the flange baffle 8-3-1 and avoid jamming during the reeling process, lubricating grease is applied to the contact surface of the spring baffle 8-4 and the flange baffle 8-3-1, thereby ensuring the smoothness of the reeling process.

[0035] See also Figure 8 , Fig. 9 , Fig.10 The full-mirror automobile sun visor with a rolling curtain described in the present invention is provided with a pre-tightening pin assembly hole 8-10 that can penetrate each other on the second fixed shaft 8-8 of the retractor 8, the second fixed shaft seat 8-9 and the rotating sleeve 8-1, and its function is: during the assembly process of the retractor 8, after the rotating sleeve 8-1 and the first fixed shaft 8-3, the first fixed shaft seat 8-2, the compression spring 8-5, the sleeve connecting seat 8-6, the winding spring 8-7, the second fixed shaft 8-8 and the second fixed shaft seat 8-9 are assembled, the second fixed shaft 8-8 is rotated to provide a pre-tightening force for the winding spring 8-7, and then the pre-tightening pin is inserted into the pre-tightening pin assembly hole 8-10, and the winding spring 8-7 is fixed by rotating the sleeve 8-1 to maintain the pre-tightening force of the winding spring 8-7.

[0036] See also Figure 1 , Figure 8 , Fig. 9 , Fig.10When the retractor 8 and the shutter box 7 in the rolling curtain assembly of the present invention are assembled, the compression spring 8-5 can be compressed by squeezing the first fixed shaft 8-3 inward. After the overall length of the retractor 8 is shortened, the outer end of the second fixed shaft 8-8 can be placed in the shutter box 7, and then the squeezing force applied to the first fixed shaft 8-3 is removed, and the elastic force of the compression spring 8-5 is released, so that the first fixed shaft 8-3 and the second fixed shaft 8-8 are respectively tightened and fixed to the two ends of the shutter box 7, and finally the pre-tightening pin inserted into the pre-tightening pin assembly hole 8-10 is removed to complete the assembly of the retractor 8.
