[0031] Existing cars are usually equipped with a sunroof system on the top to improve the ventilation effect inside and outside the car and widen the field of vision. At the same time, in order to make the sunroof able to achieve sunshade, the sunroof system is equipped with a sunshade curtain. Figure 1 As shown, the sunshade is connected to the sunshade rod 400, which is in transmission connection with the flexible shaft 300. The flexible shaft 300 is installed in the guide rail 200 and the front crossbeam plastic tube 101, and the flexible shaft 300 is in transmission connection with the driving mechanism. In this way, the driving mechanism drives the flexible shaft 300 to move back and forth in the guide rail 200 and the front crossbeam plastic tube 101, thereby driving the sunshade rod 400 and the sunshade to move back and forth, thereby realizing the opening and closing of the sunshade. However, in the process of mass production of sunroof systems, due to factors such as the size of component products, assembly dimensions, and other human influences, it is easy for the front crossbeam plastic tube 101 to be misaligned with the guide rail flexible shaft hole, and a step is formed between the front crossbeam plastic tube 101 and the guide rail flexible shaft hole. When the flexible shaft 300 passes through the step, the flexible shaft 300 rubs against the step, generating noise, affecting the user experience. At the same time, the flexible shaft 300 rubs against the step for a long time, which easily causes damage to the flexible shaft 300 and shortens its service life.

[0032] To this end, the utility model provides a connecting device for a car sunroof sunshade flexible shaft, a sunroof system and a vehicle. The connecting device can achieve low-noise and low-wear operation of the flexible shaft, improve user experience and extend the service life of the flexible shaft.

[0033] The first aspect of the utility model provides a connection device for the flexible shaft of a sunroof sunshade curtain of an automobile, Figure 2-Figure 6 As shown, the connecting device includes: a guide rail 200, a front cross beam plastic tube assembly and a connecting assembly 500 connected between the guide rail 200 and the front cross beam plastic tube assembly, the guide rail 200 includes a guide rail flexible shaft mounting groove for mounting the flexible shaft 300, an installation space for the flexible shaft 300 is formed in the front cross beam plastic tube assembly, the connecting assembly 500 includes a connecting body with an accommodating space and a first port 502 and a second port 504 respectively arranged at both ends of the accommodating space, wherein the guide rail flexible shaft mounting groove forms a guide rail flexible shaft hole 202 at one end thereof close to the connecting assembly 500, and a plastic tube port is formed at one end of the front cross beam plastic tube assembly close to the connecting assembly 500, the first port 502 is configured to be able to align and engage with the guide rail flexible shaft hole 202, and the second port 504 is configured to be able to align and engage with the plastic tube port.

[0034] In the connecting device of the automobile sunroof sunshade flexible shaft provided by the present invention, the first port 502 and the second port 504 can be aligned and engaged with the guide rail flexible shaft hole 202 and the plastic tube port respectively. In this way, there is no step between the guide rail flexible shaft hole 202 and the first port 502, and there is no step between the port of the front crossbeam plastic tube assembly and the second port 504, so that the flexible shaft 300 can run between the guide rail flexible shaft mounting groove, the accommodating space and the mounting space, and no noise will be generated when passing through the guide rail flexible shaft hole 202 and the first port 502 and the plastic tube port and the second port 504, and no wear will occur, thereby improving the user experience and extending the service life of the flexible shaft 300.

[0035] In some embodiments, the connecting body can be shaped in a variety of ways, including but not limited to a tapered tube shape, a cylindrical tube shape, etc., and can be selected and adapted based on the actual conditions of the guide rail flexible shaft hole 202 and the plastic tube port. For example, when the inner diameter of the guide rail flexible shaft hole 202 is different from the inner diameter of the plastic tube port, since the inner diameter of the first port 502 is the same as the inner diameter of the guide rail flexible shaft hole 202 and the inner diameter of the second port 504 is the same as the inner diameter of the plastic tube port, the inner diameter of the first port 502 is different from the inner diameter of the second port 504. Therefore, the connecting body can be shaped in a tapered tube, which facilitates connection between the guide rail 200 and the front crossbeam plastic tube assembly, while reducing the manufacturing cost of the connecting body.

[0036] In some embodiments, reference Figure 4 and Figure 5As shown, the connection assembly 500 further includes a positioning post 501 disposed on the side of the connection body, and the guide rail 200 includes a guide rail positioning groove 201 formed on the side of the guide rail flexible shaft hole 202. The positioning post 501 is configured to be pluggable and connected to the guide rail positioning groove 201. When the positioning post 501 is pluggable and connected to the guide rail positioning groove 201, the first port 502 is aligned and engaged with the guide rail flexible shaft hole 202. In this way, when installing the connection assembly 500, the positioning post 501 is plugged into the guide rail positioning groove 201, so that the first port 502 is aligned and engaged with the guide rail flexible shaft hole 202, achieving a self-positioning connection between the connection assembly 500 and the guide rail 200, thereby improving the work efficiency and installation accuracy of the connection assembly 500.

[0037] In some embodiments, reference Figure 4 and Figure 5 As shown, the connection assembly 500 also includes a positioning structure connected to the end face of the second port 504 and extending along the side near the front crossbeam plastic tube assembly. The positioning structure is formed with a positioning slot 503 on one side near the front crossbeam plastic tube assembly. The inner wall of the positioning slot 503 is configured to be fitted and connected with the end of the front crossbeam plastic tube assembly near the guide rail flexible shaft hole 202. When the inner wall of the positioning slot 503 is fitted and connected with the end of the front crossbeam plastic tube assembly near the guide rail flexible shaft hole 202, the second port 504 is aligned and connected with the end of the plastic tube. In this way, when installing the connection assembly 500, when the front crossbeam plastic tube assembly is fitted with the inner wall of the positioning slot 503, the second port 504 is aligned and engaged with the end of the front crossbeam plastic tube assembly, achieving a self-positioning connection between the connection assembly 500 and the front crossbeam plastic tube assembly, thereby improving the work efficiency and installation accuracy of the connection assembly 500.

[0038] In some embodiments, the front crossbeam plastic tube assembly includes the front crossbeam plastic tube 101, and the positioning slot 503 can be directly connected to the front crossbeam plastic tube 101 to achieve a self-positioning connection between the connecting assembly 500 and the front crossbeam plastic tube 101. Alternatively, in combination with Figure 5 As shown, the front crossbeam plastic tube assembly includes a front crossbeam plastic tube 101 and a plastic tube connector 102 connected to one end of the front crossbeam plastic tube 101. The wall thickness of the plastic tube connector 102 is greater than that of the front crossbeam plastic tube 101, and the inner wall of the positioning slot 503 is configured to fit the outer circumferential surface of the plastic tube connector 102. Since the wall thickness of the plastic tube connector 102 is greater than that of the front crossbeam plastic tube 101, the structural strength of the plastic tube connector 102 is greater than that of the front crossbeam plastic tube 101, thereby improving the stability of the connection between the connecting assembly 500 and the front crossbeam plastic tube assembly.

[0039] In some embodiments, the inner diameter of the plastic pipe joint 102 is the same as the inner diameter of the front crossbeam plastic pipe 101, so that the flexible shaft 300 does not generate noise and wear when passing through the plastic pipe joint 102 and the front crossbeam plastic pipe 101. At the same time, since the wall thickness of the plastic pipe joint 102 is greater than the wall thickness of the front crossbeam plastic pipe 101, as shown in FIG. Figure 5 As described, the outer wall of the plastic pipe joint 102 protrudes radially relative to the front crossbeam plastic tube 101, and the positioning structure forms an axial limiting portion 506 at one end of the positioning slot 503 close to the front crossbeam plastic tube 101. The axial limiting portion 506 abuts against the end face of the plastic pipe joint 102 close to the front crossbeam plastic tube 101, thereby preventing the plastic pipe joint 102 from moving axially, further improving the stability of the connection between the connecting assembly 500 and the front crossbeam plastic tube assembly.

[0040] In some embodiments, the connection assembly 500 provided by the present invention also includes a connection structure arranged on the outer wall of the positioning structure, which is used to connect with the front crossbeam 100, further improving the stability of the connection between the connection assembly 500 and the front crossbeam plastic pipe assembly and the guide rail 200.

[0041] The connection structure provided by the present invention has various forms. For example, in some embodiments, referring to Figure 5 and Figure 6 As shown, the connection structure includes a buckle 505 provided on the outer wall of the positioning structure, and the buckle 505 is used to be snap-connected with the slot 103 on the front crossbeam 100 , so that the connection assembly 500 is fixed on the front crossbeam 100 .

[0042] In some embodiments, the connecting structure includes a connecting plate 507 arranged on the outer wall of the positioning structure, a bolt hole 508 is formed on the connecting plate 507, and a corresponding front beam bolt hole is provided on the front beam 100. The bolt 600 is threadedly connected to the bolt hole 508 and the front beam bolt hole, so that the connecting component 500 is fixed to the front beam 100.

[0043] Or as Figure 6 As shown, the connecting structure includes a clip 505 and a connecting plate 507 respectively arranged on both sides of the outer wall of the positioning structure. The clip 505 is snap-connected with the slot 103 on the front crossbeam 100. A bolt hole 508 is formed on the connecting plate 507, and a corresponding front crossbeam bolt hole is provided on the front crossbeam 100. The bolt 600 is threadedly connected with the bolt hole 508 and the front crossbeam bolt hole, thereby further improving the stability of the connection between the connecting component 500 and the front crossbeam 100.

[0044] The second aspect of the present invention provides a skylight system, referring to Figure 2As shown, the sunroof system includes a front crossbeam 100 and a rear crossbeam that are relatively arranged, and the aforementioned connecting assembly 500, the guide rail 200 is arranged between the front crossbeam 100 and the rear crossbeam, the front crossbeam plastic tube assembly is installed on the front crossbeam 100, and the connecting assembly 500 is connected between the guide rail flexible shaft installation groove and the front crossbeam plastic tube assembly.
