Abstract
Description
Technical Field
[0001] The present invention relates to a vehicle sunroof system, in particular to a sunroof drainage structure and a vehicle. Background Art
[0002] There are generally two commonly used skylight drainage structures. One is to install the skylight drain on the skylight sheet metal structure. This structure is relatively simple and cannot be used as a debris-blocking structure. It is easy for external debris such as leaves and debris to enter the skylight drain. When the skylight drain pipe is twisted, these external impurities accumulate at the twisted part, which can easily clog the drain pipe. The other is to make the skylight drain directly on the plastic frame. Multiple filter teeth are distributed at intervals to filter external debris such as leaves and debris. However, this structure is not easy to transplant. The sunroofs of different car models must be designed separately. It is easy to have the filter teeth positioned improperly, resulting in filtration failure. At the same time, the existing skylight drain pipe layout has certain requirements on curvature, otherwise local collapse will occur, resulting in poor drainage. Summary of the Invention
[0003] In view of this, the purpose of the present invention is to provide a sunroof drainage structure and a car, which can drain the water on the sunroof assembly to the outside of the car, can keep external debris such as leaves and debris in the water outside the drain, and is not prone to distortion caused by the rotation of the drainage bellows, thereby avoiding blockage of the pipe body caused by the combined effects of the distortion of the drainage bellows and the entry of external debris.

[0031] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and embodiments.
[0032] like Figure 1-Figure 7As shown, a sunroof drainage structure in this embodiment includes a drainer 1 and a drainage bellows 2; the drainer 1 includes a water collecting bowl 11 and a water outlet pipe 12, the water outlet pipe 12 is connected to the interior of the water collecting bowl 11, and the water collecting bowl 11 is provided with a filtering water inlet structure and a sunroof connection structure; the head end of the drainage bellows 2 is connected to the water outlet pipe 12 in a non-rotatable manner, and the tail end of the drainage bellows 2 is provided with an anti-rotation connector 21. An automobile in this embodiment includes a sunroof assembly 3, an automobile sheet metal 4, and a sunroof drainage structure, the sunroof assembly 3 is provided with a connection hole, the water collecting bowl 11 is connected to the connection hole via the sunroof connection structure, and the tail end of the drainage bellows 2 is connected to the automobile sheet metal 4 via an anti-rotation connector 21. The water collecting bowl 11 passes through the connection hole of the sunroof assembly 3 from bottom to top, and is then connected to the connection hole. It can introduce water on the sunroof assembly 3 into the interior of the water collecting bowl 11 through the filtered water inlet structure, and then the water is discharged through the outlet pipe 12 and the drainage bellows 2, thereby draining the water on the sunroof assembly 3 to the outside of the vehicle. While draining the water, the filtered water inlet structure can block external debris such as leaves and debris in the water outside the drain 1. At the same time, the head and tail ends of the drainage bellows 2 are not rotatable, and are not prone to distortion caused by the rotation of the drainage bellows 2, thereby avoiding blockage of the pipe body caused by the combined effects of the distortion of the drainage bellows 2 and the entry of external debris. In addition, the drainage bellows 2 is flexible, and the bending radius of the drainage bellows 2 is varied, which improves adaptability and flexibility and reduces the difficulty of arranging the sunroof drainage structure.
[0033] In this embodiment, an anti-rotation boss 121 is provided on the outer wall of the outlet pipe 12, and an anti-rotation groove 22 is provided at the head end of the drain bellows 2. The anti-rotation boss 121 is connected to the anti-rotation groove 22. Preferably, the anti-rotation boss 121 is provided on the outer wall of the outlet pipe 12 on the side corresponding to the water collection bowl 11. Multiple anti-rotation bosses 121 may be provided at intervals along the circumference of the outlet pipe 12, for example, two or three. The insertion of the anti-rotation boss 121 into the anti-rotation groove 22 prevents the outlet pipe 12 and the drain bellows 2 from rotating relative to each other, thereby preventing the head end of the drain bellows 2 from rotating.
[0034] In this embodiment, the anti-rotation connector 21 is a non-disc-shaped body and is circumferentially provided with an annular snap-fitting groove 24. The anti-rotation connector 21 may be a special-shaped disc with one side larger than the other, or may be an elliptical disc, a pentagonal disc, a hexagonal disc, or other shapes. The automobile sheet metal 4 is also provided with a snap-fitting hole of a corresponding shape. After the anti-rotation connector 21 is inserted into the snap-fitting hole on the automobile sheet metal 4, the annular snap-fitting groove 24 snaps into the snap-fitting hole, thereby connecting the tail end of the drainage bellows 2 to the automobile sheet metal 4 via the anti-rotation connector 21. Since the anti-rotation connector 21 is a non-disc-shaped body, it can prevent the tail end of the drainage bellows 2 from rotating.
[0035] In this embodiment, a retaining projection 122 is provided on the outer wall of the outlet pipe 12. Multiple sealing tooth rings 23 are provided inside the head end of the drain bellows 2. The retaining projection 122 passes through the plurality of sealing tooth rings 23. The plurality of sealing tooth rings 23 are spaced apart along the axis of the central hole of the drain bellows 2. The retaining projection 122 is a barbed hook with a guiding slope. Passing through the plurality of sealing tooth rings 23, the retaining projection 122 prevents the outlet pipe 12 from separating from the drain bellows 2.
[0036] In this embodiment, the outer wall of the water collecting bowl 11 is provided with a protruding sealing lip 111. The water collecting bowl 11 is also provided with a water collecting upper flange 112 that protrudes upward from the sealing lip 111. The water collecting upper flange 112 is annular. After the water collecting bowl 11 is connected to the skylight assembly 3 through the connection hole of the skylight connection structure, the sealing lip 111 abuts against the lower surface of the skylight assembly 3, preventing water leakage and improving the sealing performance of the skylight drainage structure. After the water collecting bowl 11 is connected to the skylight assembly 3 through the connection hole of the skylight connection structure, the water collecting upper flange 112 protrudes upward from the skylight assembly 3, forming an annular water retaining structure.
[0037] In this embodiment, the skylight connection structure includes a plurality of engaging teeth 113 spaced apart on the water trap upper flange 112; these engaging teeth 113 facilitate assembly and disassembly. The filtered water inlet structure includes a plurality of filtered water inlet holes 114 spaced apart on the water trap upper flange 112. The water trap upper flange 112 forms an annular water retaining structure. When water flows into the skylight assembly 3 and the liquid level reaches the filtered water inlet holes 114, it can flow into the interior of the water trap bowl 11 through the filtered water inlet holes 114.
[0038] In this embodiment, the interior of the water-collecting upper flange 112 forms an upwardly opening; the water-filtering inlet structure further includes a filter grille disposed within the opening. The water-collecting upper flange 112 forms an annular water retaining structure. When water flows onto the skylight assembly 3 and the liquid level exceeds the water-collecting upper flange 112, it can flow through the opening into the water-collecting bowl 11. The filter grille can retain foreign debris, such as leaves and debris, from the drain 1 during the water inflow process.
[0039] In this embodiment, the filter grille includes a connecting rod 115 and a plurality of partitions 116 connected to the connecting rod 115; the outlet pipe 12 is arranged on the side of the water collecting bowl 11, and the axial direction of the outlet pipe 12 is perpendicular to the up and down direction; the length direction of the connecting rod 115 is along the axial direction of the outlet pipe 12, and the plurality of partitions 116 are arranged at intervals along the axial direction, and the lower parts of the plurality of partitions 116 are all provided with water holes 117 that pass through along the axial direction. The connecting rod 115 connects the plurality of partitions 116 into a whole, ensuring the overall strength. At the same time, the shape of the combination of the connecting rod 115 and the partitions 116 is simple and easy to injection mold. The water holes 117 can ensure that water passes through each partition 116 in sequence and flows into the outlet pipe 12.
[0040] In this embodiment, the plurality of partitions 116 are gradually inclined from top to bottom toward the water outlet pipe 12. The inclined partitions 116 can give the water a certain initial velocity, which is directed toward the water outlet pipe 12, making the water flow toward the water outlet pipe 12 smoother.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
