Description

Technical Field

[0001] This utility model relates to the field of automotive sunroof technology, and in particular to a sunroof sunshade assembly for vehicles. 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 publication CN 208053066U, which discloses an automotive sunroof sunshade assembly mechanism. The mechanism includes a frame for mounting to the vehicle body sheet metal, a curtain fabric disposed within the frame, and a slide rail on each of the left and right sides of the frame. Edge strips are fixed to the left and right sides of the curtain fabric, and guide strips are provided along the outer edges of the edge strips for housing within the slide rails. Multiple guide particles, evenly spaced along the length of the guide strips, are used for sliding connection with the slide rails. In use, when the guide strips along the outer edges of the edge strips slide against the slide rails, only the guide particles contact the slide rails. Even after prolonged use, the guide particles themselves do not exhibit severe deformation, and their operating state is not significantly different from that of new parts, demonstrating good stability. This design is also readily available in production.

[0004] However, existing sunshade curtain cables are taut on the frame, and the cables lack Z- and Y-axis limiting from the winding wheel to the front pulley. Vibration causes the cables to hit the frame, the cables are suspended in the air, the cables extend out from the top of the winding wheel at the rear of the frame, there is a lack of cable pressing structure, and the safety distance between the cables and the roof reinforcement sheet metal is insufficient. In view of this, we propose a sunroof sunshade curtain assembly for vehicles. Utility Model Content

[0005] The purpose of this utility model is to provide a sunroof sunshade assembly for vehicles, which at least solves the technical problems of existing car sunroofs lacking a pressure line structure, making it easy for the pull line to knock against the frame, causing abnormal noise, and affecting the stability of the sunshade over a long period of time.

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1-5This utility model provides a sunroof sunshade assembly for vehicles, including a frame assembly body 1. A roller assembly 2 is mounted on the upper surface of the frame assembly body 1. The roller assembly 2 includes a motor 21, which is fixedly connected to the inner surface of the frame assembly body 1. The frame assembly body 1 includes a front beam, guide rails, and a rear beam. A slider slides within the guide rails, fixing one end of the sunshade to the slider. The frame assembly body 1 is also fixed to the other end of the sunshade. Limiting guide blocks are installed on the guide rails at the guide rail's arc height and at the rear end of the frame. The rear beam is integrally injection molded with an integrated pressure line structure at the middle position of the guide rails. The cross-section of the frame assembly body 1... The frame assembly body 1 is arc-shaped, with multiple sets of mounting holes on its upper surface. These holes facilitate installation. The limiting and guiding structures define the direction of the pull cable, preventing knocking noises. A winding wheel 22 is fixedly connected to the output shaft of the motor 21. A spool tube 23 is fixedly connected to the inner surface of the winding wheel 22, and the spool tube 23 is rotatably connected to the inner surface of the frame assembly body 1. A wire wheel 24 is rotatably connected to the inner surface of the frame assembly body 1. A pull rope 25 is wound around the outer arc surface of the wire wheel 24, and the outer arc surface of the pull rope 25 is coated with a plastic layer. Hexagonal metal fittings are pressed together at both ends of the pull rope 25. By pressing a metal alloy onto both ends of the draw rope 25, the stability of the draw rope 25 during use can be effectively ensured. The wire rope is coated with a plastic layer, which greatly improves its performance. Simultaneously, the plastic layer effectively prevents corrosion from harmful external substances, extending its service life. The plastic coating also effectively smooths the outer arc surface of the wire rope, improving its fatigue resistance. The main material of the plastic layer can be polyethylene, polypropylene, polyvinyl chloride, or polyamide, etc. The outer arc surface of the draw rope 25 is coated, and the outer arc surface of the winding reel 22 is wound around the side of the draw rope 25 away from the reel 24. The inner surface of the frame assembly body 1 is fixedly connected with pressure plates 26 in a linear array. The inner surface of the pressure plates 26 is slidably connected to the pull rope 25. The inner surface of the frame assembly body 1 is fixedly connected with H-shaped limiting blocks 27 in a linear array. The inner surface of the H-shaped limiting blocks 27 is slidably connected to the pull rope 25. The top of the H-shaped limiting blocks 27 is rotatably connected to limiting rollers 28. There are two limiting rollers 28, which are symmetrically arranged. The inner surface of the frame assembly body 1 is provided with a curtain 29. One end of the curtain 29 is fixedly connected to the roller tube 23. The inner surface of the frame assembly body 1 is provided with a pull rod assembly. The other end of the curtain 29 is fixedly connected to the pull rod assembly.

[0026] In this embodiment, a pull-wire pressing structure is integrated on the rear beam of the frame assembly body 1, with hexagonal metal alloys pressed at both ends of the pull wire to restrict the movement of the pull wire in the Z and Y directions, thereby achieving smooth operation of the sunroof sunshade assembly. At the same time, the pull wire direction is limited by H-shaped limiting blocks 27 and pressure plates 26, which solves the problems of pull wire knocking noise and pulley derailment, and more effectively improves the stability of the entire sunroof sunshade assembly, making the overall effect more comfortable when the vehicle is in use.

[0027] The working principle of the sunroof sunshade assembly for vehicles provided by this utility model is as follows:

[0028] When the sunshade needs to be unfolded, the motor 21 is started. The motor 21 drives the winding wheel 22 and the roller tube 23 to rotate simultaneously. Through the cooperation of the wheel 24 and the pull cord 25, the slider inside the frame assembly body 1 slides in the guide rail, which drives the sunshade to unfold. At the same time, when the pull cord 25 moves with the slider, the pulley 34 rotates due to the friction between it and the pull cord 25. At the same time, the H-shaped limit block 27, the limit roller 28, and the pressure plate 26 limit the pull cord 25, so that the pull cord 25 will not hit the frame assembly body 1 when the curtain is pulled, making the whole device more stable.

[0029] 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.
