The clamping portion 105 is formed on the outer peripheral wall of the plug body 101. When the plug body 101 is installed in the drainage hole 201 opened on the vehicle body 200, the clamping portion 105 is returned to the drainage hole 201. The part of the car body 200 at the location is pressed to prevent the plug body 101 from moving along the drainage hole 201, and the annular portion 106 is arranged on the inner wall surface of the plug body 101. The through holes of all the annular portions 106 are suitable for forming the plug-in channel 102 on the above-mentioned plug body 101. When the water pipe 300 is plugged into the plug-in channel 102, the inner wall surface of the through hole of each annular portion 106 can be pressed against the outer wall surface of the water pipe 300 to apply extrusion force to the water pipe 300.

[0060] By forming an insertion channel 102 with openings at both ends on the plug body 101, one end of the water pipe 300 is inserted into the insertion channel 102, and at the same time, a clamping portion 105 is formed on the outer peripheral wall surface of the plug body 101. The clamping portion 105 is used to abut against the body 200 at the drainage hole 201, which can prevent the plug body 101 from moving along the drainage hole 201, thereby ensuring the assembly stability when one end of the water pipe 300 is inserted into the insertion channel 102 on the plug body 101. By forming an annular portion 106 on the inner wall surface of the plug body 101, all the through holes of the annular portion 106 can form the above-mentioned insertion channel 102, so that The outer wall surface of the water pipe 300 is pressed against the inner wall surface of the through hole of the annular portion 106, thereby applying an extrusion force to the water pipe 300 to ensure that the water pipe 300 can be stably plugged into the plug-in channel 102, ensuring the installation stability of the water pipe 300 and the vehicle body 200. At the same time, the annular portion 106 can also be used to ensure the sealing between the water pipe 300 and the plug body 101, thereby reducing the risk of water leakage, reducing the damage rate to the car sunroof, and extending the service life of the car sunroof. The overall structure of the plug is simple and easy to form, which can effectively reduce the production cost and subsequent assembly difficulty, and is conducive to improving the assembly efficiency in actual vehicle production.

[0061] In this embodiment, the annular portion 106 is an annular boss, and the through hole of the annular boss is used to form the plug-in channel 102. In actual setting, the inner diameter of the through hole of the annular boss is set equal to the outer diameter of the outer wall of the water pipe 300, thereby ensuring that after the water pipe 300 is plugged into the plug-in channel 102, the outer wall of the water pipe 300 can be fitted with the inner wall of the annular boss.

[0062] The number of the annular portion 106 may be one, or two or more.

[0063] In actual use, in order to further improve the installation stability of the plug relative to the vehicle body 200 after the plug is installed in the drain hole 201, the above-mentioned clamping portion 105 can be continuously formed on the outer peripheral wall surface of the plug body 101. This arrangement can increase the contact area between the clamping portion 105 and the vehicle body 200, thereby increasing the contact area between the plug body 101 and the vehicle body 200, and further improving the installation stability.

[0064] The above-mentioned clamping portion 105 is of an annular structure. Of course, a plurality of discontinuous arc-shaped bosses may also be provided on the outer peripheral wall surface of the plug body 101 , and all the arc-shaped bosses together form the clamping portion 105 .

[0065] See also Figure 3Taking the example of setting the above-mentioned clamping part 105 in a ring structure, an opening groove 107 is formed between the above-mentioned clamping part 105 and the outer wall surface of the plug body 101, and the part of the vehicle body 200 is located in the opening groove 107, which can prevent the vehicle body 200 from detaching from the plug body 101, and further improve the installation stability between the plug body 101 and the vehicle body 200.

[0066] In actual use, in order to further improve the installation stability between the plug body 101 and the vehicle body 200 , a tip recess may be provided at the bottom end of the opening groove 107 , which can further prevent the vehicle body 200 from detaching from the plug body 101 .

[0067] Specifically, the above-mentioned pointed recess can be set as a groove with a pointed shape, wherein the bottom of the groove is pointed. When the plug body 101 is installed in the drain hole 201, the inner wall surface of the drain hole 201 can extend into the groove to prevent the vehicle body 200 and the plug body 101 from detaching, thereby further improving the installation stability between the plug body 101 and the vehicle body 200.

[0068] In the skylight water pipe plug structure of the present embodiment, the inner wall surface of the above-mentioned drainage hole 201 is abutted against the bottom wall surface of the opening groove 107. In actual use, the opening groove 107 is arranged in a U-shaped structure. It should be noted that the radial dimension of the ring formed by the groove bottom of the U-shaped groove is equal to the inner diameter dimension of the drainage hole 201, thereby ensuring that the inner wall surface of the drainage hole 201 and the bottom wall surface of the opening groove 107 can be abutted, thereby achieving the sealing between the plug body 101 and the water pipe 300.

[0069] In order to improve the sealing performance between the clamping portion 105 and the vehicle body 200 , the clamping portion 105 may be tilted relative to the plug body 101 along the extending direction from the first end toward the second end of the plug body 101 .

[0070] By tilting the snap-on portion 105 relative to the plug body 101 along the extension direction from the first end toward the second end of the plug body 101, the interference between the snap-on portion 105 and the vehicle body 200 can be increased, ensuring reliable sealing and preventing curling of the snap-on portion 105.

When the water pipe 300 is inserted into the insertion channel 102, the convex rib 108 is pressed against the outer wall surface of the water pipe 300.

[0073] In actual use, the outer surface of any of the above-mentioned ribs 108 can be set to a circular arc surface. By setting the outer surface of the rib 108 to a circular arc surface, the friction coefficient when the water pipe 300 is assembled through the plug channel 102 on the plug body 101 can be reduced, thereby reducing the assembly force, and ensuring sufficient sealing. The inner diameter of the inner wall surface of the rib 108 is set to be slightly smaller than the plug channel 102, that is, the inner diameter of the annular portion 106, so as to ensure that the water pipe 300 can be inserted into the plug channel 102 while ensuring the sealing between the plug body 101 and the water pipe 300.

[0074] In this embodiment, two convex ribs 108 are provided, and one convex rib 108 is provided at both ends of the annular portion 106 , with a gap between the two convex ribs 108 .

[0075] In order to reduce the difficulty of assembly, a countersunk hole 103 may be provided at the end of the plug body 101 . The countersunk hole 103 is coaxially arranged with the plug channel 102 , and the inner diameter of the countersunk hole 103 is larger than the inner diameter of the plug channel 102 .

[0076] By setting a countersunk hole 103 at the end of the plug body 101, the countersunk hole 103 is coaxial and connected with the plug channel 102, and the inner diameter of the countersunk hole 103 is larger than the inner diameter of the plug channel 102, the annular portion 106 is pressed through the countersunk hole 103 during assembly, and force is easily applied during assembly, so easy assembly can be achieved.

[0077] In actual use, the depth of the countersunk hole 103 is set to be about half the depth of a thumb, about 3 cm, so that the thumb can be inserted into the countersunk hole 103 and apply force.

[0078] In this embodiment, a guiding bevel 104 can be formed on the outer wall surface of the plug body 101. By forming the guiding bevel 104 on the outer wall surface of the plug body 101, it plays a guiding role in the process of installing the plug body 101 into the drainage hole 201, which is conducive to assembling the plug body 101 into the drainage hole 201 on the vehicle body 200, and further reduces the assembly force.

[0079] In actual use, the plug is made of rubber material, so that the plug body 101, the clamping portion 105, the annular portion 106 and the convex rib 108 can be integrally formed, and the rubber material can be EPDM soft material.
