[0003] In order to solve the above-mentioned technical problems in the prior art, the purpose of this utility model is to provide a universal wire harness clip installation structure.

[0004] This utility model discloses a universal wiring harness clip installation structure, including a bumper cover, a wiring harness, a wiring harness strip, a wiring harness clip, and a fixing bracket. The wiring harness is connected to the wiring harness clip via the clamping surface of the wiring harness strip. The wiring harness clip is a rigid plastic part with an embedded spring steel sheet. The fixing bracket includes a bracket panel and a snap-fit ​​rib provided on the bracket panel. The bracket panel is bonded to the bumper cover, and the spring steel sheet is snap-fitted to the snap-fit ​​rib. The back of the bracket panel is provided with a transverse groove structure and a longitudinal groove structure.

[0005] The interference fit between the spring steel sheet and the snap-fit ​​rib is 0.5mm to 0.8mm.

[0006] The bracket panel is bonded to the first adhesive surface of 3M adhesive, while the second adhesive surface of 3M adhesive is bonded to the bumper skin.

[0007] The local thickness of the bracket panel is reduced to 0.6mm to 0.7mm through the transverse groove structure and the longitudinal groove structure.

[0008] The bumper skin is an injection-molded plastic part.

[0009] The fixing bracket is a rigid plastic component.

[0010] The snap-fit ​​rib has a thin sheet-like structure.

[0011] The snap-fit ​​rib has triangular reinforcing ribs on both sides that connect to the support panel.

[0012] Compared with the prior art, the universal wire harness clip mounting structure of this utility model has the following advantages:

[0013] ① Using independent fixed brackets to install wire harnesses can avoid the problems of poor product qualification rate and poor appearance due to injection molding defects (shrinkage marks);

[0014] ② The fixed bracket is used for both front and rear bumpers as well as parts with high appearance requirements, achieving standardization and reducing the development cost of parts. Attached Figure Description

[0024] The following will further elaborate on the universal wire harness clip installation structure of this utility model with reference to specific embodiments, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the technical solution of this utility model.

[0025] Example 1

[0026] like Figure 2-9 As shown, the generalized wire harness clip mounting structure of this embodiment is mainly used for mounting wire harnesses on bumpers or other exterior parts. Specifically, the wire harness clip mounting structure includes a bumper skin 1, a wire harness 2, a wire harness strip 3, a wire harness clip 4, and a fixing bracket 5. The bumper skin 1 is an injection-molded plastic part, the wire harness clip 4 is a rigid plastic part with an embedded spring steel sheet 410, and the fixing bracket 5 is a rigid plastic part. The fixing bracket 5 includes a bracket panel 550 and a snap-fit ​​rib 510 disposed on the bracket panel. The snap-fit ​​rib 510 is in the shape of a thin sheet, and triangular reinforcing ribs 540 connected to the bracket panel are provided on both sides of the snap-fit ​​rib 510. The bracket panel 550 is bonded to the first bonding surface 610 of 3M adhesive 6, while the second bonding surface 620 of the 3M adhesive 6 is bonded to the bumper skin 1. The back of the bracket panel 550 is provided with a transverse groove structure 530 and a longitudinal groove structure 520, which makes the local thickness of the bracket panel 550 thinner, such as... Figure 7-8 As shown, the local thickness of the bracket panel 550 is f and g, where f and g can be set to 0.6–0.7 mm. This allows for adaptation to different curvature surfaces of bumper skins or other exterior parts even with a relatively thin material thickness. Utilizing the excellent adhesive properties of 3M adhesive, effective connections to different locations on the bumper skin or other exterior parts are achieved, maintaining good stability. The wire harness 2 is connected to the wire harness clip 4 via the clamping surface 310 of the wire harness strip 3. The wire harness clip 4 has an embedded spring steel sheet 410, which is engaged with the locking rib 510. The interference fit c between the spring steel sheet 410 and the locking rib 510 is 0.5 mm–0.8 mm. The triangular reinforcing rib 540 effectively strengthens the fixed bracket, improving the locking strength of the wire harness bracket.

[0027] For those skilled in the art, the specific embodiments are merely exemplary descriptions of the present invention. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention are within the protection scope of the present invention.
