[0001] This invention relates to the field of automotive design, and in particular to a modular wiring harness sealing method for automobiles. Background Technology

[0002] Currently, due to design and layout requirements, automotive wiring harnesses need to pass through holes in the body panels while also meeting waterproof and dustproof requirements, thus giving rise to the need for sealing.

[0003] Currently, common sealing materials are usually made of rubber, but it is difficult to achieve sealing requirements for large radial dimensions. Another type is pure foam sealing, but its manufacturing process requires specialized large-scale equipment, occupies too much space, and is not conducive to sealing the wire harness; therefore, it needs improvement. Summary of the Invention

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 , Figure 2 As shown, a modular wiring harness seal for automobiles includes a sealing ring 1, a sealing ring 2, a sealing plate 3, and a foaming agent reactor 4.

[0033] like Figure 1 , Figure 2 As shown, the sealing ring 1 is fitted onto the wire harness. A raised ring 11 is coaxially arranged on the outer wall of the sealing ring 1. The raised ring 11 is used to embed into the sheet metal holes in the vehicle body, thereby sealing the holes. The outer wall of the raised ring 11 and the outer wall of the sealing ring 1 have an inclined stepped surface 12 to facilitate compression deformation, increasing the sealing performance between the sealing ring 1 and the sheet metal, achieving dustproof and waterproof effects. Alternatively, the sealing ring 1 can be composed of two semi-circular rubber rings with a snap-fit ​​structure, made of high-temperature and high-pressure resistant rubber.

[0034] like Figure 1 , Figure 2 As shown, the sealing ring 2 is fitted onto the wire harness, and a filling space 5 is left between the inner side of the sealing ring 2 and the outer wall of the wire harness. The sealing plate 3 is fixed to the outer side of the sealing ring 2 and fitted onto the wire harness, and is used to seal the filling space 5. The foaming agent reactor 4 is used to fill the entire filling space 5 after a chemical reaction, so as to achieve a seal between the sealing ring 1 and the wire harness.

[0035] like Figure 1 , Figure 2As shown, the sealing ring 2 is formed by the interlocking of a pair of semi-circular ring bodies, and a locking mechanism 21 is provided between the pair of ring bodies to achieve the assembly and fixation of the sealing ring 2. The sealing plate 3 is formed by the interlocking of a pair of semi-circular ring plates, and the sealing plate 3 is fixed to the sealing ring 2, realizing the synchronous and rapid assembly of the sealing ring 2 and the sealing plate 3. Several vent holes 31 are provided through the sealing plate 3. The vent holes are used to allow the air in the filling space 5 to be quickly discharged when the foaming agent reactor 4 undergoes a chemical reaction, ensuring the stable sealing of the wire harness.

[0036] Therefore, when sealing the wire harness, the sealing ring 1 is installed on the wire harness, and then the protruding ring 11 on the sealing ring 1 is embedded into the sheet metal hole to seal the sheet metal hole. Then, the sealing ring 2 and the sealing plate 3 are fastened onto the wire harness, and the locking clip 21 is used to fix the sealing ring 2 and the sealing plate 3, so that a relatively sealed filling space 5 is formed between the sealing ring 2, the sealing plate 3 and the sealing ring 1.

[0037] Finally, the foaming agent reactor 4 is used to inject foam into the filling space 5. As the foam increases, it will firmly fix the wire harness, sealing ring 2, sealing plate 3 and sealing ring 1 together, and fill the gaps between the four to achieve a sealing effect.

[0038] Therefore, by using a sealing method with built-in foam filling function, the wire harness location that needs to be sealed can be sealed anytime, anywhere and accurately. It is easy to install, requires no special equipment, has reliable sealing, saves time and effort, reduces manufacturing costs, solves the sealing needs of large radial wire harnesses, and also solves the problems of complex installation and multiple manufacturing sites.

[0039] like Figure 2 , Figure 3 As shown, the foaming agent reactor 4 includes a reaction bag 41, a drive plate 42, and a needle 43. There are two reaction bags 41, both of which are semi-circular and embedded in the sealing ring 2. The inner diameter of the reaction bag 41 is smaller than the inner diameter of the sealing ring 2, and it abuts against the outer wall of the wire harness.

[0040] like Figure 2 , Figure 3 As shown, two drive plates 42 are provided, both of which are arc-shaped. The two ends of the drive plates 42 are connected to the outside of the sealing ring 2 by elastic elements 44, which are springs or elastic ropes, and serve to fix the drive plates 42. The outer wall of the sealing ring 2 is provided with a limiting groove 22 for the drive plates 42 to be inserted, so as to restrict the drive plates 42 to move only along the depth direction of the limiting groove 22.

[0041] like Figure 2 , Figure 3As shown, a locking plate 45 is provided between each end of a pair of drive plates 42, and the two ends of the locking plate 45 are fixed to the sealing ring 2 by connecting posts 46. The connecting posts 46 can be broken off, and after breaking off, the locking plate 45 can be removed to release the restriction on the drive plates 42.

[0042] like Figure 2 , Figure 3 As shown, the drive plate 42 has an internal cavity 47 filled with a reactant 48. The cavity also has a certain pressure to ensure that the reactant 48 can be quickly discharged. The needle 43 is tubularly disposed inside the drive plate 42. One end of the needle 43 is connected to the cavity 47, and the other end is sealed.

[0043] like Figure 2 , Figure 3 As shown, a through hole 23 is passed through the sealing ring 2, and an elastic membrane 24 is disposed inside the through hole 23. The lower end of the needle 43 is bent and has a certain curvature. At the same time, a folding groove 49 is provided at the bent position of the needle 43. Therefore, when the control drive plate 42 moves, the needle 43 abuts against the elastic membrane 24 without directly piercing the elastic membrane 24. At this time, the sealing end of the needle 43 breaks off, and then pierces the elastic membrane 24 and the reaction bag 41, so that the reactant 48 comes into contact with the substance in the reaction bag 41 and a chemical reaction occurs to form foam.

[0044] After the sealing is installed, twist the locking plate 45 to break it at the connecting post 46 to release the restriction on the drive plate 42. Then press the drive plate 42 to move along the depth of the limiting groove 22. The needle 43 on the drive plate 42 passes through the through hole 23 on the sealing ring 2 and abuts against the elastic membrane 24. Since the elastic membrane 24 has a certain toughness and the end of the needle 43 has a folding groove 49, the needle 43 will break at the folding groove 49.

[0045] Then, continue pressing the drive plate 42 so that the needle 43 pierces the elastic membrane 24 and then the reaction bag 41. At this time, the reactant 48 flowing out of the needle 43 comes into contact with the substance in the reaction bag 41 and produces foam, which causes the foam to expand rapidly. Therefore, at the same time, under the venting action of the vent hole 31 on the sealing plate 3, the foam can quickly and stably fill the entire filling space 5, thus achieving the sealing of the wire harness.

[0046] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
