Technical Field
[0001] This utility model relates to the technical field of automotive sunroof components, and in particular to a roller assembly snap-fit structure for a direct-drive sunshade. Background Technology
[0002] Car sunshades are used to block sunlight from the left, right, front, and rear windows of a car. The roller assembly's reset component is a device used to rewind and reset the sunshade cloth when it is in the unfolded state.
[0003] A search revealed Chinese patent application CN 217994073 U, which discloses a reset component for an anti-deformation car sunshade roller assembly. The component includes a main body with a light-blocking cloth wound around its surface. Mounting seats are located at both ends of the main body. Symmetrically arranged torsion springs are arranged on the inner side of the main body, and shafts penetrate the inner sides of each torsion spring. One end of each torsion spring is fixed to the surface of the shaft, and the other end is fixed to the inner wall of the main body. One end of each symmetrically arranged shaft is fixed to the side of the mounting seat. By designing a support seat, limiting rotating block, limiting rotating groove, limiting groove, and ball bearings, the invention improves upon the insufficient support found in existing car sunshades during use. By adding a support seat inside the main body of the car sunshade, support is provided to the main body while ensuring normal and flexible use, preventing deformation after long-term use and thus ensuring the service life of the car sunshade.
[0004] In existing technologies, the winding wheel of a sunshade is engaged with the roller tube. Due to space limitations caused by the reinforcing ribs of the winding wheel, the overlap in the Y direction between the winding wheel engagement structure and the roller tube is insufficient. Furthermore, the engagement between the outer surface of the winding wheel engagement structure and the inner surface of the aluminum tube is subject to manufacturing tolerances, preventing a secure connection. During the opening and closing of the sunshade, the roller and aluminum tube exhibit misalignment. During operation, the roller assembly is subjected to tension from the tension cable and the curtain fabric, resulting in vertical jumping noises and curtain wrinkling. Therefore, we propose a roller assembly engagement structure for a direct-drive sunshade. Utility Model Content

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.
[0025] Example 1
[0026] Please see Figures 1-5This utility model provides a roller assembly snap-fit structure for a direct-drive sunshade, including a frame assembly 1. The frame assembly 1 includes an assembly composed of a front beam, a rear beam, etc., which together form a complete skylight frame. A roller assembly 2 is provided on the inner surface of the frame assembly 1. The roller assembly 2 includes a motor 21, which is fixedly connected to the inner surface of the frame assembly 1. The output shaft of the motor 21 is fixedly connected to a winding wheel 22. An aluminum tube 23 is fixedly connected to the inner surface of the winding wheel 22. A roller tube 25 is snap-fitted onto the inner surface of the winding wheel 22. Two sets of winding wheels 22 are provided and symmetrically arranged with the center line of the roller tube 25 as the axis of symmetry. Meanwhile, the outer side of the snap-fit structure of the winding wheel 22 is provided with multiple limiting ribs, which correspond one-to-one with the limiting grooves 24. This setting facilitates the installation of the spool tube 25. The inner arc surface of the winding wheel 22 is fixedly connected with reinforcing ribs 26 in a circumferential array. The overall shape of the reinforcing ribs 26 is flower-shaped. This shape design cleverly avoids the spool tube 25, allowing the spool tube 25 to be better inserted into the root of the winding wheel 22. At the same time, the reinforcing ribs 26 surround the spool tube 25, which serves to limit the spool tube 25 and increase the coaxiality between the winding wheel 22 and the spool tube 25. The inner surface of the reinforcing ribs 26 is fixedly connected with U-shaped ribs 27. The inner surface of the spool tube 25 has a U-shaped slot 211. The U-shaped slot 211 is used to limit the assembly angle of the winding wheels 22 on both sides of the spool tube 25. The inner arc surface of the aluminum tube 23 has a limit groove 24 in a linear array. The outer arc surface of the aluminum tube 23 has an installation groove 28. The winding groove of the winding wheel 22 is spiral. The outer arc surface of the winding wheel 22 has a wire release groove 29. The wire release groove 29 on the outer arc surface of the winding wheel 22 can hold the pull rope 34 in the wire release groove 29, making the whole device more stable. The inner surface of the frame assembly 1 is provided with a pull plate assembly 3. The pull plate assembly 3 includes a guide rail 31. The guide rail 31 is fixed to the frame assembly 1. The inner surface of the guide rail 31 is slidably connected to a slider 32, and the inner surface of the frame assembly 1 is rotatably connected to a roller 33. A pull rope 34 is wound around the outer arc surface of the roller 33. The slider 32 is fixedly connected to one end of the sunshade body 36, and the inner surface of the frame assembly 1 is fixedly connected to the other end of the sunshade body 36. The slider 32 slides in the guide rail 31. This setting ensures the stability of the entire device. The inner surface of the frame assembly 1 is fixedly connected to a pressure plate 35. One end of the pull rope 34 is fixedly connected to the pressure plate 35, and the other end of the pull rope 34 is fixedly connected to the winding wheel 22. The setting of the pressure plate 35 ensures that the pull rope 34 always remains taut.
[0027] In this embodiment, multiple reinforcing ribs 26 are provided inside the winding wheel 22. The multiple reinforcing ribs 26 are arranged in a flower shape to avoid the spool tube 25, so that the spool tube 25 can be better inserted into the root of the winding wheel 22. At the same time, the flower-shaped ribs surround the spool tube 25, which serves to limit the spool tube 25 and increase the coaxiality between the winding wheel 22 and the spool tube 25. By adding a U-shaped rib 27 to the reinforcing rib 26 of the winding wheel 22, and opening a U-shaped slot 211 on the U-shaped rib 27, the assembly angle of the winding wheels 22 on both sides of the spool is limited. With the arrangement of the motor 21, the sunshade body 36 and the pull plate assembly 3, the operation is achieved without jumping up and down and producing abnormal noise.
[0028] The working principle of the roller assembly snap-fit structure of the direct-drive sunshade curtain of this utility model is as follows:
[0029] When assembling the roller assembly 2, the aluminum tube 23 is fixed inside the winding wheel 22. After the aluminum tube 23 is secured inside the winding wheel 22 by the mounting groove 28 on the outer arc surface of the aluminum tube 23, the roller tube 25 is aligned with the multiple limiting grooves 24 of the aluminum tube 23 and inserted into the aluminum tube 23 until the root of the winding wheel 22. At the same time, the outer arc surface of the roller tube 25 is surrounded by the reinforcing ribs 26 to ensure the stability of the roller tube 25 and the winding wheel 22. Then, the output shaft of the motor 21 is inserted into the winding wheel 22. The motor 21, the winding wheel 22 and the roller tube 25 are installed in the frame assembly 1. At the same time, the pull rope 34 is passed through the pressure plate 35 and wound around the roller 33. After the pull rope 34 is connected to the winding wheel 22, the problem of abnormal noise caused by the up-and-down jumping of the sunshade body 36 during winding and unfolding can be reduced.
[0030] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
