Embodiment Construction

[0028] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0029] In this embodiment, the stretching reel is composed of a mandrel 1, a rubber tube 2, a torsion spring 3, a shock-absorbing and sound-insulating tube 4, and an aluminum tube 5 from the inside to the outside. The rod 1 and the rubber tube 2 are relatively fixed, while the torsion spring 3, the shock-absorbing and sound-insulating tube 4 and the aluminum tube 5 can rotate relative to the mandrel 1. One end of the mandrel 1 is a flat structure, which can be matched with the external car sunroof.

[0030] like Figure 1 to Figure 4 As shown, a compression and stretching reel, the compression and stretching reel includes a mandrel 1, a torsi...

Abstract

The invention discloses a companding scroll and an assembly method thereof. The companding scroll comprises a core rod, a torsion spring, and an aluminum tube, wherein the core rod, the torsion spring, and the aluminum tube are sequentially arranged from the inside to the outside; the core rod is provided with an opening, a limiting block, and an end part slotting, and the limiting block is a telescopic arc-shaped block; a rotor is arranged at one end of the torsion spring, a stator is arranged at the other end of the torsion spring, the rotor is provided with a plurality of protrusions, the rotor can drive the torsion spring to rotate to deform the torsion spring, and the stator fixes the other end of the torsion spring and stores the elastic potential energy of the torsion spring; and aplurality of grooves are formed in the aluminum tube, and the protrusions on the rotor can cooperate with the grooves in the aluminum tube. According to the companding scroll and the assembly method thereof, the structure is simple, a sunshade curtain can be quickly retracted under the action of the core rod, the torsion spring, and the aluminum tube, the noise generated when the sunshade curtainis retracted can be greatly reduced, and the performance is stable.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a stretching reel and an assembly method thereof. Background technique [0002] With the rapid development of the automobile industry, more and more cars are equipped with sunroofs. The existence of sunroofs can effectively improve the air circulation rate in the car and bring comfortable enjoyment to the people in the car. At the same time, the existence of sunroofs also A wide view can be obtained, so that the occupants in the car can get better enjoyment. In order to prevent direct sunlight from entering the car, it is usually necessary to install a sunshade on the sunroof. [0003] During the installation process of the sunshade, it is usually necessary to pre-tighten the reel structure in the sunshade, but the existing reel structure of the sunshade has problems such as complex structure, unstable performance, short service life and high noise, which seriously...
