The sliding guide rail 3 is slidably arranged at the top end of the fixed guide rail 2. A sliding groove 6 is opened on the side of the sliding guide rail 3 facing the drainage groove 5. A shielding plate 7 is slidably arranged inside the sliding groove 6. Two positioning shafts 8 are provided at one end of the shielding plate 7. A sliding hole 9 is provided at a position corresponding to the positioning shaft 8 on the fixed groove 1.
[0034] In this embodiment, the fixed guide rail 2 is installed at the top end of the vehicle body through the setting of the fixed groove 1, and the sliding guide rail 3 is clamped into the fixed guide rail 2. At this time, the sliding guide rail 3 can slide along the direction of the fixed guide rail 2. One end of the shielding plate 7 is connected to the fixed groove 1 through the cooperation of the positioning shaft 8 and the sliding hole 9. When the sliding guide rail 3 moves, the shielding plate 7 is limited by the positioning shaft 8 to prevent the shielding plate 7 from following the sliding guide rail 3. When the sliding guide rail 3 moves to open the sunroof, the shielding plate 7 will fall on the upper surface of the fixed guide rail 2 under the influence of gravity, as Figure 6 shown. By shielding the upper surface of the fixed guide rail 2 with the shielding plate 7, it can effectively prevent dust from falling on the upper surface of the fixed guide rail 2, effectively avoid dust accumulation, and further effectively reduce the wear of the sliding guide rail 3 and the fixed guide rail 2 during sliding friction, achieving the purpose of improving the service life of the sliding guide rail 3 and the fixed guide rail 2;
[0035] On the other hand, when the sliding guide rail 3 moves to close the sunroof, since the shielding plate 7 is inside the sliding groove 6, when the sliding guide rail 3 gradually closes, the shielding plate 7 will still slide into the inside of the sliding groove 6, which can effectively prevent the dust on the surface of the shielding plate 7 from falling between the sliding guide rail 3 and the fixed guide rail 2.
[0036] In a further preferred embodiment of the present utility model, as Figures 1 - 8 shown, a dust removal mechanism 10 is provided at one end of the side wall of the sliding groove 6 corresponding to the positioning shaft 8.
[0037] In this embodiment, through the arrangement of the dust removal mechanism 10, when the sliding guide rail 3 moves to close the skylight, the dust removal mechanism 10 rolls on the upper surface of the shielding plate 7, so that the dust falling on the upper surface of the shielding plate 7 is pushed into the interior of the drainage groove 5. During rainy days or car washes, this dust will be discharged from the vehicle body through the drainage groove 5.
[0038] In a further preferred embodiment of the present utility model, as Figures 1 - 8 shown, a trapezoidal clamping block 11 is provided on the inner groove wall of the installation groove 4.
[0039] In this embodiment, the trapezoidal clamping block 11 is provided to limit the fixed guide rail 2, so as to improve the stability of the fixed guide rail 2, effectively prevent the fixed guide rail 2 from tilting when the sliding guide rail 3 moves, and enable the fixed guide rail 2 to be quickly disassembled and installed, effectively achieving the purpose of facilitating the replacement of the fixed guide rail 2.
[0040] In a further preferred embodiment of the present utility model, as Figures 1 - 8 shown, clamping grooves 12 matching the trapezoidal clamping block 11 are provided on both sides of the fixed guide rail 2.
[0041] In this embodiment, through the arrangement of the clamping grooves 12, when in use, they cooperate with the trapezoidal clamping block 11 to connect the fixed guide rail 2 and the fixed groove 1, and achieve the purpose of facilitating the installation of the fixed guide rail 2;
[0042] Specifically, when connecting the fixed guide rail 2 and the fixed groove 1, one end of the fixed guide rail 2 is inserted into the installation groove 4, and the position of the clamping groove 12 is made to correspond to the position of the trapezoidal clamping block 11. At this time, the fixed guide rail 2 is inserted into the interior of the installation groove 4 until the two ends of the fixed guide rail 2 and the fixed groove 1 are aligned.
[0043] In a further preferred embodiment of the present utility model, as Figures 1 - 8 shown, positioning grooves 13 are formed at positions of the fixed guide rail 2 and the sliding guide rail 3 corresponding to the positioning shaft 8.
[0044] In this embodiment, the positioning groove 13 is provided for positioning to fix the installation directions of the guide rail 2 and the sliding guide rail 3. During installation, one end with the installation groove 13 corresponds to the position of the positioning shaft 8. Furthermore, through the setting of the positioning groove 13, one end of the shielding plate 7 is connected to the fixed groove 1 while being parallel to the sliding guide rail 3 and the fixed guide rail 2, so as to facilitate the shielding plate 7 to shield the fixed guide rail 2 and achieve the purpose of dust prevention.
[0045] In a further preferred embodiment of the present utility model, as Figures 1 - 8 shown, the dust removal mechanism 10 includes a connecting shaft 101.

A plurality of threaded grooves 103 are formed on the outer surface of the dust removal roller 102, and the outer wall of the dust removal roller 102 is in contact with the upper end of the shielding plate 7.
[0046] In this embodiment, the connecting shaft 101 is provided for installing the dust removal roller 102, and as Figure 7 shown, one end of the dust removal roller 102 is in contact with the upper end wall of the fixed groove 1. Furthermore, during the movement of the sliding guide rail 3, the dust removal roller 102 will rotate under the influence of the fixed groove 1, so as to flatten the shielding plate 7 while scraping off the dust accumulated on the surface area of the shielding plate 7 through the threaded grooves 103.
[0047] In a further preferred embodiment of the present utility model, as Figures 1 - 8 shown, the shielding plate 7 is flexibly arranged, and the side wall of the shielding plate 7 is attached to the wall of the installation groove 4.
[0048] In this embodiment, through the flexibly arranged shielding plate 7, after the sliding guide rail 3 moves, the shielding plate 7 will fall under the influence of gravity. At this time, the bottom wall of the shielding plate 7 is fixedly connected to the fixed guide rail 2, which can effectively avoid the problem that dust contacts the fixed guide rail 2 and adheres to the surface of the fixed guide rail 2. At the same time, the side wall of the shielding plate 7 is attached to the wall of the installation groove 4, further reducing the possibility of dust contacting the fixed guide rail 2, thereby achieving the purpose of extending the service lives of the fixed guide rail 2 and the sliding guide rail 3.
[0049] In a further preferred embodiment of the present utility model, as Figures 1 - 8 shown, an extension plate 14 is provided on the side wall of the fixed groove 1, and a plurality of bolt holes 15 are formed inside the extension plate 14 for connecting the fixed groove 1 and the vehicle body.
