[0033] The sunroof drain pipe joint 100 according to the embodiments of the present application is described below with reference to the drawings.
[0034] As Figure 1As shown, the sunroof drain pipe joint 100 according to the embodiment of the utility model is used for a sunroof, the sunroof comprises a sunroof body, the sunroof body is equipped with a water guide groove, and the sunroof drain pipe joint 100 comprises a joint body 1.
[0035] Specifically, referring to the accompanying drawings Figure 2 As shown, the joint body 1 comprises a first section 11, the first section 11 has a first channel 111, and two ends of the first section 11 are a first end 112 and a second end 113 respectively; the first end 112 is connected with the sunroof body, the first channel 111 is communicated with the water guide groove, and it can be understood that because the sunroof is not completely closed, a small amount of rainwater, car washing water and the like may seep into the sunroof from the gap of the rubber strip of the sunroof; the seeped water first flows into the water guide groove and flows to the first end 112 of the first section 11 along the extension direction of the water guide groove, flows towards the second end 113 of the first section 11 after entering the first channel 111, and finally flows to the drain pipe and then to the bottom of the vehicle through the drain pipe, thereby achieving effective drainage.
[0036] Further, referring to the accompanying drawings Figure 2 As shown, the cross-sectional area of the first channel 111 gradually decreases in the direction from the first end 112 to the second end 113, and by relatively increasing the cross-sectional area of the one end of the first channel 111 communicated with the water guide groove, the area of the water inlet of the joint body 1 can be significantly increased, the drainage efficiency of the sunroof drain pipe joint 100 is improved, the water in the water guide groove can be quickly drained, the risk of water overflow in the water guide groove is reduced, the sunroof seepage or leakage is avoided, thereby reducing the possibility of affecting the window lifter and the sound box system, avoiding the interior trim panel of the vehicle from being damp, and the case that bacteria breed due to long-term water accumulation in the water guide groove can be avoided, and the use experience of the user is improved.
[0037] According to the sunroof drain pipe joint 100 of the embodiment of the utility model, by limiting that the cross-sectional area of the first channel 111 gradually decreases in the direction from the first end 112 to the second end 113, the cross-sectional area of the one end of the first channel 111 communicated with the water guide groove can be relatively increased, the area of the water inlet of the joint body 1 can be significantly increased, the drainage efficiency of the sunroof drain pipe joint 100 is improved, the water in the water guide groove can be quickly drained, the risk of water overflow in the water guide groove is reduced, the sunroof seepage or leakage is avoided, thereby reducing the possibility of affecting the window lifter and the sound box system, avoiding the interior trim panel of the vehicle from being damp, and the case that bacteria breed due to long-term water accumulation in the water guide groove can be avoided, and the use experience of the user is improved.
[0038] In some embodiments of the utility model, referring to the accompanying drawings Figure 2 As shown, in the axial direction perpendicular to the first section 11 (referring to the accompanying drawings Figure 2As shown in the third direction, the cross-section of the first channel 111 is circular or elliptical. Specifically, the maximum length of the first channel 111 in the first direction (the vertical direction of the vehicle) is a, and the length of the first channel 111 in the second direction is b. The first direction, the second direction and the axial direction of the first segment 11 are perpendicular to each other, and a≤b, which can satisfy the size of the first channel 111 in the first direction. Furthermore, by increasing the length of the first channel 111 in the second direction, the cross-sectional area of the first channel 111 is further increased, ensuring the drainage efficiency of the sunroof drain pipe joint 100.
[0039] When the cross-section of the first channel 111 is circular, such as Figure 2 As shown, this can reduce the manufacturing difficulty of the first segment 11 and facilitate the manufacturing of the connector body 1. When the cross-section of the first channel 111 is elliptical, the space of the skylight in the vertical direction is limited, so the length of the first channel 111 in the vertical direction cannot be extended too much. However, the cross-sectional area of the first channel 111 can be further increased by increasing the length of the first channel 111 in the horizontal direction, thus ensuring the drainage efficiency of the skylight drain pipe connector 100.
[0040] In some embodiments of this utility model, reference is made to the appendix. Figure 3 As shown, the connector body 1 also includes a second segment 12, which is connected to the second end 113 of the first segment 11. The second segment 12 has a second channel 121, which runs along the axial direction of the second segment 12 (see attached diagram). Figure 3 As shown, the third segment (extending in the direction of the sunroof) connects to the first channel 111. It can be understood that water seeping into the sunroof's rubber seal first flows into the water guide channel and then along the extension direction of the water guide channel to the first end 112 of the first segment 11. After entering the first channel 111, it flows towards the second end 113 of the first segment 11, and then flows into the second channel 121 of the second segment 12. Finally, it flows from the end of the second segment 12 away from the first segment 11 to the drain pipe, and from the drain pipe to the bottom of the vehicle, achieving effective drainage. It should be noted that the design of the second segment 12 facilitates the connection of the sunroof drain pipe connector 100 with the original specification drain pipe, enhancing the applicability and compatibility of the sunroof drain pipe connector 100 and improving the user experience.
