Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 The present invention will be further described in detail below:

[0022] This utility model discloses a novel automotive wiring harness sealing structure, such as... Figure 1 As shown, this utility model discloses a novel automotive wiring harness sealing structure, including a wire groove 1 with an upper opening. A top cover 2 is rotatably connected to the upper opening of the wire groove 1. A rotating assembly for fixing the opening and closing position of the top cover 2 is provided on the side wall of the top cover 2. Both ends of the wire groove 1 have through-holes 11 for the wiring harness to pass through. The interior of the wire groove 1 is provided with several wiring harness fixing mechanisms for securing the wiring harness. In this embodiment, the two ends of the wire groove 1 have openings for the wiring harness to enter. The wiring harness is placed inside the wire groove 1. When the wiring harness needs to be connected to other wiring harnesses, the different wiring harnesses are connected through interfaces, and the connection position is placed inside the wire groove 1. By providing a rotatable top cover 2 at the upper opening of the wire groove 1, and cooperating with the rotating assembly to achieve a stable closure of the top cover 2, the corrosion of the wiring harness by external environmental factors such as moisture and dust is effectively prevented, improving the sealing performance of the wiring harness. The rotating assembly makes the opening and closing operation of the top cover 2 simple and quick, requiring no complex tools, facilitating the inspection, repair, and replacement of the wiring harness, and reducing maintenance costs. By installing a wire harness fixing mechanism within the wire harness trough 1, the wire harness can be kept from shaking, reducing the risk of damage. After the wire harness is placed, the gap between the wire harness trough 1 and the top cover 2 is sealed with adhesive, and the openings at both ends of the wire harness 1 are also sealed to increase its airtightness. During maintenance, a special adhesive remover is used to remove the sealant, and then the rotating component can be used to open the top cover 2.

[0023] like Figure 2 , Figure 3 , Figure 4 As shown, the rotating assembly includes a slide rod 31, a first spring 32, and a cap 33; the slide rod 31 is fixedly connected to the side wall of the upper cover 2, the cap 33 is slidably connected to the outer side wall of the slide rod 31, one end of the first spring 32 is fixedly connected to the outer side wall of the cap 33, and the other end of the first spring 32 is fixedly connected to the side wall of the upper cover 2. A groove 34 is formed through the side wall of the wire groove 1, and the cap 33 can slide within the groove 34; in this embodiment, the positions of the slide rod 31 and the spring are as follows. Figure 2As shown, the shape of the groove 34 is as follows Figure 3 As shown. The spring is sleeved on the outside of the slide rod 31. By providing the slide groove 34, the slide rod 31 and the cap 33 can cooperate with the slide groove 34, thereby allowing the upper cover 2 to be in a vertical open state and a horizontal closed state.

[0024] like Figure 4 As shown, the bolt cap 33 includes a first pin portion 331 and a second pin portion 332, which are integrally formed. The diameter of the first pin portion 331 is smaller than the diameter of the second pin portion 332. The width of the sliding groove 34 is smaller than the diameter of the second pin portion 332 but larger than the diameter of the first pin portion 331. Pin holes 341 are respectively provided at both ends of the sliding groove 34. The second pin portion 332 can cooperate with the pin holes 341 to fix the position of the upper cover 2. In this embodiment, the specific shape of the bolt cap 33 is as follows: Figure 4 As shown, both the first pin portion 331 and the second pin portion 332 are cylindrical, with a frustum-shaped transition between them. The diameter of the pin hole 341 is slightly larger than the diameter of the second pin portion 332, and the diameter of the second pin portion 332 is larger than the width of the slide groove 34. The width of the slide groove 34 is larger than the diameter of the first pin portion 331. Therefore, the second pin portion 332 cannot slide within the slide groove 34. When the second pin portion 332 enters the pin hole 341, it will be fixed in the pin hole 341, thus fixing the upper cover 2 in a fixed position.

[0025] like Figure 1 , Figure 5 As shown, the wire harness fixing mechanism includes a limiting block 41, a second spring 42, and a sliding post 43. The sliding post 43 is fixedly connected to the inner wall of the wire groove 1. A sliding hole 44 is provided on the side wall of the limiting block 41. The limiting block 41 is slidably connected to the sliding post 43 through the sliding hole 44. One end of the second spring 42 is fixedly connected to the side wall of the limiting block 41, and the other end of the second spring 42 is fixedly connected to the inner wall of the wire groove 1. In this embodiment, the limiting block 41 includes a limiting part 411. The end of the limiting part 411 is bent towards the bottom wall of the wire groove 1 and rounded. In use, the wire harness is pressed down from the upper side of the limiting part 411. Due to the shape of the limiting part 411, the limiting block 41 will slide towards the sliding post 43 and compress the second spring 42. After the wire harness enters the interior of the limiting block 41, the limiting block 41 will move towards the wire harness position under the push of the second spring 42 and finally abut against the inner wall of the wire groove 1. Preferably, the number of wire harness fixing mechanisms is N, where N≥2.

[0026] like Figure 6 As shown, a reinforcing rib 12 is provided at the bottom of the wire trough 1; in this embodiment, the structural strength of the wire trough 1 is improved by providing the reinforcing rib 12.

[0027] The implementation principle of this utility model embodiment is as follows:

[0028] In use, the wire harness is pressed down from the upper side of the limiting part 411. Due to the shape of the limiting part 411, the limiting block 41 will slide towards the sliding post 43 and compress the second spring 42. After the wire harness enters the inside of the limiting block 41, the limiting block 41 will move towards the wire harness position under the push of the second spring 42 and finally abut against the inner wall of the wire groove 1.

[0029] When closing the top cover 2, press the cap 33 to allow the first pin 331 to enter the pin hole 341. Rotate the top cover 2, and when the first pin 331 moves along the slide groove 34 to the pin hole 341 at the other end, the spring will push the second pin 332 into the pin hole 341, thus closing the top cover 2. After the wire harness is placed, seal the gap between the wire groove 1 and the top cover 2 by applying glue, and seal the openings at both ends of the wire groove 1.
