Examples

The embodiments of the present invention will be described in detail below, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.

Example 1

A rolling curtain mechanism with isolator damping is structurally shown in figures 1-5 and comprises a mirror frame 1, a cosmetic mirror 4 and a rolling curtain 2 with isolator damping, wherein the cosmetic mirror 4 is assembled on the mirror frame 1.

The structure of the rolling screen 2 is shown in fig. 4, and comprises an upper cover plate 19, an upper cover plate 20 and a toggle button 21, wherein one end of the rolling screen 2 is welded between the upper cover plate 19 and the upper cover plate 20, and the other end is pasted on the scroll unit 3. Two cushions 23 are installed at one side of the upper cover plate 20. A plurality of magnets 22 are arranged between the upper cover plate 19 and the upper cover plate 20 to provide attraction force between the roller blind 2 and the mirror frame 1 when the roller blind is closed.

The structure of the reel unit 3 is shown in fig. 2, and comprises an aluminum sleeve 6, and a first fixed shaft sleeve 7 and a second fixed shaft sleeve 12 are respectively arranged at two ends of the sleeve 6. Notches 17 are arranged on the side walls of two ends of the sleeve 6, and a boss 18 matched with one notch 17 is arranged on the outer wall of the first fixed shaft sleeve 7. The first fixed boss 7 is opened at both ends, one end of the isolator 8 passes through the first fixed boss 7, and the isolator 8 and the damper 9 are connected by a connecting pin 28. The damper 9 is connected with a torsion spring 10, the other end of the torsion spring 10 is connected with a second fixing shaft sleeve 12, a boss 18 is also arranged outside the locking shaft tube 11 and is matched with another gap 17 of the sleeve 6, the locking shaft tube 11 is also provided with openings at two ends, and the second fixing shaft sleeve 12 penetrates through the inside of the locking shaft tube 11. One end of the isolator 8 is provided with a riveting column 13, one end of the second fixed shaft sleeve 12 is provided with an installation block 14, the outer wall of the damper 9 is provided with a positioning bulge 16, and the inside of the sleeve 6 is provided with a positioning groove 15 matched with the positioning bulge 16.

The frame 1 comprises a plurality of magnets 22, and the magnets 22 on the roller blind 2 form an adsorption force. The frame 1 is provided with a metal strip 5 to prevent abnormal noise during the recovery of the roller shutter 2. The lenses are assembled in the slots of the frame 1. As shown in fig. 5, the side of the frame 1 is provided with a riveting hole 24 and a mounting hole 25 which are opposite to each other and are respectively matched with the riveting column 13 and the mounting block 14.

The isolator 8 of the present embodiment is a bearing type isolator, and the structure of the isolator and the damper 9 is as shown in fig. 3, the isolator 8 includes an outer bearing 26 and an inner bearing 27, and one end of the outer bearing 26 is provided with a rivet post 13 and fixed to the frame 1 by riveting. The rotation between the outer bearing 26 and the inner bearing 27 can occur in only one direction, and the locking is caused when the rotation is reversed, which is a characteristic principle of the isolator 8 itself. The damper 9 includes a damping outer sleeve 30, a damping inner rotor 29 and damping oil 31 filled therebetween, wherein the damping inner rotor 29 is connected with the inner bearing 27 by the connecting pin 28, and one end of the torsion spring 10 is fixed with the damping outer sleeve 30. The outer wall of the damping housing 30 is provided with positioning projections 16 (not shown in fig. 3).

The working principle of the structure is as follows:

when the roller shutter 2 needs to be opened (i.e. the cosmetic mirror 4 is covered), the toggle button 21 is pulled, at this time, the roller shutter 2 drives the sleeve 6 to rotate, so as to drive the locking shaft tube 11, the damper outer sleeve 30, the first fixing shaft sleeve 7 and the locking shaft tube 11 to rotate together, at this time, the second fixing shaft sleeve 12 and the outer bearing 26 of the isolator 8 are fixed with the mirror frame, so that the second fixing shaft sleeve 12 cannot rotate, so that one end of the torsion spring 10 cannot rotate; the damper housing 30 rotates to rotate the other end of the torsion spring 10, so that the torsion spring 10 is deformed to start storing force while pulling the roll screen 2. During this time, the rotation of the damping outer sleeve 30, due to the presence of the damping oil 31, also brings about a synchronous rotation of the damping inner rotor 29 and, via the connecting pin 28, the inner bearing 27, in the direction of rotation in which a relative rotation between the outer bearing 26 and the inner bearing 27 can take place. When the roller blind 2 is completely opened, one end of the roller blind 2 is attracted to the mirror frame 1 by the magnet 22.

When the cosmetic mirror 4 is required to be used, the roller shutter 2 is closed (even if the cosmetic mirror 4 is exposed). At this time, the knob 21 is manually pulled to separate the magnet 22 from the frame 1, and then the knob 21 is released, so that the movable end of the roll screen 2 loses tension and can be freely retracted. The torsion spring 10 releases its elasticity, that is, the torsion spring 10 rotates reversely, because one end of the torsion spring 10 is fixed to the second fixing shaft sleeve 12 and cannot rotate, the damping outer sleeve 30 can be driven to rotate reversely when the torsion spring 10 releases the elasticity, so as to drive the sleeve 6 to rotate reversely, and the sleeve 6 rotates reversely, so that the roller blind 2 is rolled on the sleeve 6. Since the inner bearing 27 cannot rotate oppositely to the outer bearing 26, the inner bearing 27 cannot rotate in the process, and the damping inner rotor 29 cannot rotate due to the existence of the connecting pin, so that the damping inner rotor 29 and the damping outer sleeve 30 can rotate relatively, and the relative rotation speed between the damping inner rotor 29 and the damping outer sleeve 30 cannot be very high due to the existence of the damping oil 31, so that the rotation speed of the damping outer sleeve 30 cannot be very high, the rolling speed of the roller shutter 2 is reduced, and the rolling noise is reduced. When the roll screen 2 is completely rolled up, the impact force is further reduced by the cushion pad 23.

The embodiments described above are presented to enable a person having ordinary skill in the art to make and use the present application. It will be readily apparent to those skilled in the art that various modifications to these embodiments may be made, and the generic principles described herein may be applied to other embodiments without the use of the inventive faculty. Therefore, the present application is not limited to the embodiments herein, and those skilled in the art, in light of the present disclosure, will recognize that changes may be made in the form and detail of the embodiments without departing from the scope or spirit of the application.
