[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or at least two of the related listed items.

[0041] As Figures 1 to 4As shown in the figure, the wire harness through-hole sealing structure 100 provided by the present application includes a sheet metal 10, a seal 20, a fixing member 30, and a wire harness 40. A wire passing hole 11 is formed in the sheet metal 10, and a connecting rod 12 is provided around the wire passing hole 11 of the sheet metal 10. The seal 20 is abutted against the sheet metal 10 and is inserted and matched with the connecting rod 12. The seal 20 includes a sealing lip 21 and an extension portion 22. The sealing lip 21 is disposed around the wire passing hole 11 and is in abutting seal with the sheet metal 10. The extension portion 22 is disposed at the position where the wire passing hole 11 is located and is communicated with the wire passing hole 11. The fixing member 30 abuts against the seal 20 and is connected to a portion of the connecting rod 12 passing through the seal 20 for fixing the seal 20 to the sheet metal 10. The wire harness 40 passes through the extension portion 22. Among them, the portion of the wire harness 40 located within the extension portion 22 is assembled and sealed with the extension portion 22 in a tight fit manner. That is to say, the seal 20 can use the sealing lip 21 to achieve the assembly seal between it and the sheet metal 10, use the extension portion 22 to achieve the assembly seal between it and the wire harness 40, and achieve the assembly seal between the wire harness 40 and the sheet metal 10. Here, the sheet metal 10 is specifically the front apron of an automobile.

[0042] As can be seen from the above, the seal 20 is fixed to the sheet metal 10 by the pressing of the fixing member 30 connected to the connecting rod 12, and the assembly seal between the seal 20 and the sheet metal 10 is achieved by deforming the sealing lip 21 by extrusion. When the seal 20 is assembled on the sheet metal 10, it is not necessary to overcome the deformation of the seal 20 itself, the installation difficulty is small, the probability of violent installation by workers is reduced, and thus damage to the wire harness 40 can be avoided.

[0043] As Figure 3 、 Figure 4 shown, the sealing lip 21 is annular. That is to say, the sealing lip 21 forms a sealing ring after being deformed under pressure on the sheet metal 10, so that the assembly seal between the seal 20 and the sheet metal 10 can be achieved after the sealing lip 21 is deformed under pressure, which can simplify the structure of the sealing lip 21. It can be understood that in other embodiments, the sealing lip 21 can also achieve the assembly seal between the seal 20 and the sheet metal 10 in a labyrinth manner, which will not be elaborated here.

[0044] As Figure 4 shown, the number of the sealing lips 21 is configured to be at least two, and at least two sealing lips 21 are independently arranged from each other. That is to say, the seal 20 and the sheet metal 10 can be multi-sealed with at least two sealing lips 21, which can ensure the sealing performance of the assembly between the seal 20 and the sheet metal 10. Here, the number of the sealing lips 21 is configured to be two. It can be understood that in other embodiments, the number of the sealing lips 21 can also be three, four, or even at least two, which will not be elaborated here.

[0045] AsFigure 2 As shown, the extension part 22 extends outward through the wire threading hole 11; wherein, the extension part 22 is conical. In this way, by using the conical structure of the extension part 22, it is convenient for the wire harness 40 to thread through the extension part 22, and it can also increase the contact area between the wire harness 40 and the extension part 22 to ensure the sealing performance of the assembly between the extension part 22 and the wire harness 40.

[0046] As Figure 2 , Figure 4 shown, the extension part 22 has an extension head 221, and the extension head 221 is arranged at one end of the extension part 22 far from the sheet metal 10; wherein, the thickness of the extension head 221 is greater than the thickness of other parts of the extension part 22. It should be noted that since the extension part 22 is conical, the aperture of the extension head 221 on the extension part 22 can be minimized, which can prevent the extension part 22 from being bent during the wire threading process of the wire harness 40. In this way, it is further convenient for the wire harness 40 to thread through the extension part 22 and ensure the sealing performance of the assembly between the wire harness 40 and the extension part 22.

[0047] As Figure 3 , Figure 4 shown, the sealing member 20 is provided with a through hole 23, the through hole 23 is arranged corresponding to the connecting rod 12, and the connecting rod 12 can pass through the corresponding through hole 23 and then be connected to the fixing member 30; wherein, the number of the through holes 23 is configured to be at least two, and at least two through holes 23 are arranged at intervals along the circumferential direction of the sealing member 20. That is to say, there are at least two fixing points between the sealing member 20 and the sheet metal 10, which can meet the use requirements of the assembly of the sealing member 20 on the sheet metal 10 and ensure the assembly stability of the sealing member 20 when assembled on the sheet metal 10. Here, the number of the through holes 23 is configured to be four, and the four through holes 23 are arranged symmetrically in pairs. It can be understood that the number of the through holes 23 is not limited to the four shown in the figure. In other embodiments, the number of the through holes 23 can also be two, three, five, or even more, and will not be elaborated here.

[0048] As Figure 2 , Figure 3 shown, the fixing member 30 is connected to the connecting rod 12 in a threaded manner. In this way, by using the threaded fit structure between the fixing member 30 and the connecting rod 12, on the one hand, it is convenient to connect the fixing member 30 to the connecting rod 12, so as to facilitate the assembly and fixing of the sealing member 20 on the sheet metal 10; on the other hand, it can also adjust the pressing force when the sealing member 20 is pressed on the sheet metal 10 to ensure the sealing performance of the assembly between the sealing member 20 and the sheet metal 10. It can be understood that the connection manner between the fixing member 30 and the connecting rod 12 is not limited to the threaded fit structure shown above. In other embodiments, the connection manner between the fixing member 30 and the connecting rod 12 can also be tight fitting, snap connection, welding, etc., and will not be elaborated here.

[0049] As Figure 3 shown, the connecting rod 12 is configured as a screw; and / or, the fixing member 30 is configured as a nut. When the connecting rod 12 is a screw and the fixing member 30 is a nut, the structural characteristics of the screw and the nut are utilized, so that the connecting rod 12 and the fixing member 30 can use local materials, which has the effect of reducing costs. It can be understood that in other embodiments, the connecting rod 12 can also be a screw, and the fixing member 30 can also be a screw sleeve, etc., which will not be elaborated here.

[0050] As Figure 2 、 Figure 3 shown, the connecting rod 12 penetrates through the sheet metal 10 and is connected to the sheet metal 10 by welding, so that the assembly connection of the connecting rod 12 on the sheet metal 10 can be realized to meet the use requirement that the seal 20 abuts against the sheet metal 10. Here, the connecting rod 12 has a limiting head 121. After the connecting rod 12 passes through the sheet metal 10, the limiting head 121 can be used to abut against the sheet metal 10, so that the assembly limit of the connecting rod 12 on the sheet metal 10 can be realized. After that, the connecting rod 12 can be fixed to the sheet metal 10 by welding.

[0051] In addition, the present application also provides an automobile, including the wire harness through-hole sealing structure 100 described above.

[0052] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered that the scope described in this specification.
