Description

Technical Field

[0001] The present invention relates to the technical field of skylight machinery, and particularly relates to a sunshade curtain reel with a torsion spring for energy storage and capable of reducing noise and eliminating noise. Background Art

[0002] With the rapid development of the automotive industry, more and more cars are equipped with skylights. The presence of skylights can effectively improve the air circulation rate inside the vehicle, bringing comfortable enjoyment to the passengers inside the vehicle. At the same time, the presence of skylights can also provide an open view, enabling the passengers inside the vehicle to enjoy better. In order to avoid direct sunlight entering the vehicle, a sunshade curtain is usually installed on the skylight.

[0003] Before installing the sunshade curtain into the automotive skylight system, it is necessary to pre-tighten the torsion spring inside the sunshade curtain reel first. The length of the torsion spring will become longer and more twisted, resulting in a relatively large noise generated by the reel structure during use, affecting the feelings of the passengers inside the vehicle. Secondly, at present, there are many types of sunshade curtain reels, with complex structures and many parts, requiring high skills of personnel. At the same time, it increases the product mold cost, production cost of changing production lines, etc. Summary of the Invention

The length of the rubber noise reduction tube is designed to be longer than the natural state of the torsion spring, ensuring that the entire torsion spring can be covered during use to reduce noise and eliminate noise. The entire spring pin group assembly is optimized to reduce the volume of the parts of this assembly. At the same time, the installation position and the O-ring direction guiding structure on the installation and reset spring pin are optimized. Through this structure, the O-ring can be guided in place and in full interference contact with the spring pin fixing seat, which can increase the damping during pressing and reduce the installation difficulty and noise of personnel. Finally, the internal design of the general-purpose reel without an iron core is optimized and can be installed with a skylight with an iron core structure. By transforming the structures of the O-ring and the noise reduction tube, the strong stiffness and flexibility of the O-ring and the noise reduction and shock absorption effect of the noise reduction tube are significantly improved.

[0046] During operation, first install the sunshade curtain scroll Figure 1Assemble as shown. Install the scroll spring pin 2, return spring 4, and scroll O-ring 5 from the opening direction at one end of the scroll, and combine them with the spring pin fixing seat 3 to form a damping elastic component; the torsion spring L-shaped hooks 10-1 at both ends of the scroll torsion spring 10 are aligned with the torsion spring tail fixing seat 6 and the rotating end cap 9 respectively in the middle of the scroll torsion spring 10. The torsion spring L-shaped hook 10-1 is clamped in the L-shaped hook clamping groove to realize the clamping connection between the torsion spring tail fixing seat 6 and the scroll torsion spring 10. The torsion spring L-shaped hook 10-1 is inserted into the L-shaped hook installation hole to realize the clamping connection between the rotating end cap 9 or the rotating iron core module 12 and the scroll torsion spring 10, forming a moving component; the damping elastic component and the rotating end fixing seat 8 are installed and fixed in the internal groove of the scroll inner tube 1 to limit and form a static component; install the rubber sound-absorbing tube 7 on the moving component and install it with the static component to form a scroll; rotate the rotating end of the scroll to store corresponding energy, and control the noise generated by the scroll torsion spring 10 during the energy storage process of the rubber sound-absorbing tube 7 when it becomes longer and twisted. After completing the energy storage, insert the fixing pin 11 to fix the rotating end fixing seat 8 and the rotating end cap 9 or the rotating iron core module 12. Rotate the rotating end cap 9 or the rotating iron core module 12. The rotating end cap 9 or the rotating iron core module 12 drives the scroll torsion spring 10 to rotate. The scroll torsion spring 10 becomes longer due to rotation to form energy storage. The fixing pin 11 is inserted into the rotating end cap 9 or the rotating iron core module 12, so that the rotating end cap 9 or the rotating iron core module 12 is fixed on the rotating end fixing seat 8. Therefore, the rotating end cap 9 or the rotating iron core module 12 cannot move. At this time, there is spring torsion energy storage in the scroll torsion spring 10. The O-ring reinforcing rib 5-2 of the O-ring body 5-1 and the metal rubber cylinder 5-8 embedded therein can supplement and enhance the stiffness of the scroll O-ring 5, improve the service life of the scroll O-ring 5. The O-ring installation convex 5-3 can enhance the installation firmness of the scroll O-ring 5 and prevent the scroll O-ring 5 from falling off due to vibration. The metal rubber sleeve 5-5, flexible ceramic sleeve 5-6, and metal support cylinder 5-7 can significantly enhance the stiffness and flexibility of the scroll O-ring 5 and greatly improve the performance of the scroll O-ring 5. The sound-absorbing tube support 7-4 of the sound-absorbing tube body 7-1 plays a supporting role for the sound-absorbing tube body 7-1. The flexible ceramic sound-absorbing plate 7-5 embedded inside the sound-absorbing tube support 7-4 significantly enhances the stiffness and flexibility of the sound-absorbing tube body 7-1. The sound-absorbing tube outer sound-absorbing pad 7-6 and sound-absorbing tube inner sound-absorbing pad 7-7 attached to the inner and outer surfaces of the sound-absorbing tube body 7-1 significantly enhance the sound-absorbing and shock-absorbing effects of the sound-absorbing tube body 7-1. The sound-absorbing tube sound-absorbing holes 7-8 on the sound-absorbing tube body 7-1 and the sound-absorbing hole sound-absorbing pads 7-9 attached to the inner wall surfaces of the sound-absorbing tube sound-absorbing holes 7-8 can supplement the sound-absorbing and shock-absorbing effects of the sound-absorbing tube outer sound-absorbing pad 7-6 and sound-absorbing tube inner sound-absorbing pad 7-7.

[0048] In the present invention, the length of the rubber sound insulation tube in the sunshade curtain scroll is designed to be longer than the natural state of the torsion spring, so as to ensure that the whole torsion spring can be covered during use for noise reduction. The whole spring pin group assembly is optimized to reduce the volume of the components of this assembly. At the same time, the direction guiding structure and installation position of the O-ring installed on the installation reset spring pin are optimized. Through this structure, the O-ring can be guided in place and in full interference contact with the spring pin fixing seat, which can increase the damping during pressing and reduce the installation difficulty and noise of personnel. Finally, the internal use of a coreless structure universal scroll is optimized and can be installed with a skylight with an installed iron core structure. By transforming the structures of the O-ring and the sound insulation tube, the strong stiffness and flexibility of the O-ring and the sound insulation and shock absorption effect of the sound insulation tube are significantly improved, thereby significantly improving the actual use effect of the whole scroll, having obvious technical advantages and market application value.
