For example, if the wiring harness through-hole is an oblong hole, if an existing product is used to guide the wire downward, and the wire through-line direction required by the project is to pass the wire to the left, then in this case, a new automotive rubber part needs to be redesigned and developed, or if the project requires the wire to be diagonally downward at 45 degrees, then a new rubber part needs to be opened. In this way, a large number of automotive rubber parts will be newly opened due to different wire through-line directions, resulting in low platform utilization of rubber parts, and thus a certain waste of the cost of the wiring harness assembly.

[0005] Therefore, there is an urgent need for a wire harness guide that can meet the requirements of wire harness passing in any direction, is conducive to platform use, and effectively reduces the cost of wire harness assembly. Utility Model Content

[0034] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 7As shown, a wire harness guide provided in an embodiment of the utility model comprises a body 1, at least one wire guide duct 2 for the wire harness to enter and exit, and at least one guide structure 3; wherein,

[0036] The body 1 is made of rubber and is provided with at least one through hole 11, and a corresponding guide structure 3 is fixed in each through hole 11;

[0037] Each wire guide tube 2 is made of rubber;

[0038] Each guide structure 3 is made of rubber and is ring-shaped, and its outer ring is fixed to a corresponding through hole 11, and the inner ring is sleeved on the outer wall of a corresponding wire guide tube 2 and fixed, and a deformation part 31 is formed between the inner and outer rings to provide a displacement deformation amount when the wire guide tube 2 is sleeved when an external force acts in any direction, that is, external forces such as stretching, compression and bending act on the wire guide tube 2, so that the wire harness outlet of the wire guide tube 2 can be flexibly changed in multiple directions.

[0039] It should be noted that the deformation portion 31 of each guide structure 3 has a certain deformation margin, and its outer contour cross section includes but is not limited to a U-shape, an inverted U-shape (such as Figure 2 As shown), Z-shaped, S-shaped or wavy folds, etc.

[0040] It is understandable that the number of wire guides 2 assembled on the body 1 can be designed according to actual conditions (such as 2 or more), and the number of guide structures 3 must match the number of wire guides 2, so that different wire harnesses can have different exit directions after entering the corresponding wire guides 2. At this time, the guide structure 3 can realize the exit of the wire harness in the wire guide 2 in any direction according to the needs, and can absorb a certain manufacturing tolerance of the wire harness, which is more convenient for assembly.

[0041] In the embodiment of the utility model, in order to facilitate the wiring harness to enter conveniently and the wiring direction is substantially the same, the inner ring of each guide structure 3 can be set to be fixed on the outer wall of the end of the wire guide tube 2 facing the body 1, and as close to the end surface outer wall as possible. At the same time, the end of each wire guide tube 3 away from the connected guide structure 2 is located on the same side of the body 1, so that all the wiring directions are substantially the same and the angle or length can be adjusted by the guide structure 3.

[0042] In the embodiment of the utility model, each guide structure 3 can be fixed to the wire guide 2 connected to it by adhesive or other means, but considering the phenomenon of fatigue or falling off of both due to excessive use, it is best that each guide structure 3 is integrally formed with the wire guide 2 connected to it. Similarly, each guide structure 3 can also be fixed to the body 1 by adhesive or other means, but it is best that all guide structures 3, all wire guides 2 and the body 1 are integrally formed. In this case, the guide structure 3 can reduce the stress on the body 1 when the wire harness is bent, ensuring the stability of the installation of the body 1.

[0043] In the embodiment of the utility model, the wire harness guide is often applied to the car after the frame is assembled. Therefore, the wire harness guide also includes: a frame 4 matched with the body 1; wherein the frame 4 is a box body made of plastic with an opening (such as an opening facing upward), and an annular flange 41 is formed around the opening of the box body; the body 1 extends a certain length on the circumferential outer edge in the direction away from each wire guide 2 to form an annular brim 12, and at least one protrusion 121 is provided on the inner wall of the brim 12; wherein, when the body 1 and the frame 4 are assembled together, the brim 12 is covered and installed on the flange 41, and the protrusion 121 of the brim 12 is abutted on the side of the flange 41 away from each wire guide 2, so as to lock the body 1 and the frame 4. Of course, when the body 1 and the frame 4 are disassembled, the brim 12 is forced outward to break open, so that the protrusion 121 of the brim 12 is separated from the flange 41, and the body 1 and the frame 4 are separated by force.

[0044] It can be understood that in order to make the assembly of the main body 1 and the skeleton 4 more compact and reliable, at this time, the wiring harness guide also includes: an inner ring 5; wherein the inner ring 5 is made of rubber, installed in the brim 12 and located on the side of the protrusion 121 away from the flange 41 (that is, above the protrusion 121), and it forms an interference fit with the flange 41 of the skeleton 4, that is, when the main body 1 and the skeleton 4 are locked, the inner ring of the inner ring 5 is sleeved on the outer wall of the flange 41, and the outer ring of the inner ring 5 is pressed against the inner wall of the brim 12.

[0045] In the embodiment of the utility model, the frame 4 is usually installed on the body sheet metal (not shown), so the outer wall of the box body of the frame 4 is provided with a plurality of locks 42 for cooperating with the body sheet metal, and the plurality of locks 42 are all arranged away from the flange 41 (that is, away from the main body 1 and located below the flange 41); wherein, when the frame 4 is assembled on the body sheet metal, the plurality of locks 42 are locked with the body sheet metal.

[0046] In the embodiment of the utility model, the assembly process of the wire harness guide and the frame is specifically as follows: first, the hole diameter of the wire guide 2 on the main body 1 is expanded to the required size using a hole expander to allow all the main wire harnesses to pass through the wire guide 2; then, an appropriate amount of waterproof cement is added between the internal wires at the two end ports of all the wire guides 2; after the waterproof cement is added, PVC tape is wrapped around the outlet wires of all the wire guides 2, and then the assembly of the main body 1 and the frame 2 is completed; finally, the locking buckle 42 on the frame 4 is used to complete the installation and matching with the body sheet metal.

[0047] Figure 5 This is a cross-sectional view of the compressed state of the wire outlet after the wire harness guide is assembled with the frame provided in the embodiment of the utility model. At this time, when the main body of the wire harness guide is assembled with the frame, if there is a positive tolerance between the positioning dimension of the next fixed point of the wire harness, that is, the wire harness is too long, the wire outlet of the wire guide 2 of the main trunk of the wire harness needs to be compressed inwards so that the excessively long part of the wire harness is compressed in the frame 4 by the pressure plate.

[0048] Figure 6 This is a plan view of the wire outlet in the stretched state after the wire harness guide and the frame are assembled in the embodiment of the utility model. At this time, when the main body of the wire harness guide is assembled with the frame, if there is a negative tolerance between the positioning dimension and the next fixed point of the wire harness, that is, the wire harness is short, the wire outlet of the wire guide 2 of the main trunk of the wire harness needs to be stretched outward to pull the wire harness to the next fixed point.

[0049] Figure 7 This is a plan view of the bending state of the wire outlet after the wire harness guide is assembled with the frame provided in the embodiment of the utility model. At this time, after the main body of the wire harness guide is assembled with the frame, the wire harness can be directed out in any direction according to actual needs. When the wire harness is bent, when stress is applied to the wire outlet of the wire guide 2, the guide structure 3 is compressed near the bending direction and stretched away from the bending direction, so that the stress on the wire outlet of the wire guide 2 is absorbed by the guide structure 3, and will not be transmitted to the main body 1 to affect the stability.
