[0022] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0023] This utility model discloses a wiring harness sheath for vehicles.

[0024] Reference Figure 1 , Figure 2 , Figure 3A vehicle wiring harness sheath includes a flexible sheath body 1 and a bracket 2. The flexible sheath body 1 has a wiring harness conduit 4 for the wiring harness to pass through. The bracket 2 is used to support the flexible sheath body 1 and install the flexible sheath body 1 at a corresponding position on the vehicle body. The side of the flexible sheath body 1 that contacts the vehicle body is integrally formed into a waterproof structure. By installing the flexible sheath body 1 at the corresponding position on the vehicle body and using the waterproof structure and the vehicle body in an interference fit, there is no need to rely on additional fillers such as waterproof cement, simplifying the waterproofing process, improving waterproofing performance, and effectively avoiding the water intrusion problems caused by traditional waterproof structures.

[0025] In this embodiment, the flexible sheath 1 is a rubber sleeve. The wire harness conduit 4 is integrally formed and inclinedly disposed on the flexible sheath 1. The wire harness conduit 4 has a through hole for the wire harness to pass through. The wire harness passes through the through hole and enters the wire harness hole in the vehicle body. Utilizing the extensibility of the rubber sleeve, the through hole and the rubber sleeve form an interference fit, which can effectively prevent moisture, dust, etc. from entering the vehicle body interior, improve waterproof performance and sealing performance. In addition, the rubber sleeve can meet the installation requirements of wire harnesses of different diameters, improving applicability.

[0026] The wire harness conduit 4 has a sheath installation direction indicator 3, which is an indicator arrow integrally formed on the outside of the wire harness conduit 4. During installation, workers can identify the installation direction of the rubber sleeve through the sheath installation direction indicator 3. Workers can avoid installing it backwards or incorrectly, reduce rework and wasted time caused by incorrect installation, reduce the complexity of worker operation, and thus improve overall production efficiency.

[0027] In this embodiment, the bracket 2 can be made of metal, alloy and plastic materials, and the rubber sleeve is installed on the bracket 2. Specifically, the flexible sheath body 1 is provided with a sheath fixing member 5, which is integrally formed on the flexible sheath body 1.

[0028] The sheath fastener 5 is approximately cylindrical, and it has a fastener limiting part 6. The diameter of the fastener limiting part 6 is larger than the diameter of the sheath fastener 5, while the diameter of the sheath fastener 5 is slightly smaller than the diameter of the wire harness. The bracket 2 has a bracket hole. The fastener limiting part 6 passes through the bracket hole sheath, allowing the sheath fastener 5 to snap into the bracket hole. The sheath fastener 5 and the bracket hole have an interference fit. Because the fastener limiting part 6 is made of rubber, it is elastic and can completely pass through the bracket hole and snap into it. The rubber fastener limiting part 6 can be easily compressed during installation and returns to its original shape after passing through the bracket hole, achieving quick snap-in. The interference fit design ensures that the sheath fastener 5 is stable and reliable after snap-in and can also effectively prevent loosening caused by vibration. The elasticity of the rubber material can absorb vibration and impact, reduce wear between the fastener and the bracket hole, and extend service life.

[0029] In this embodiment, the bracket 2 is provided with a bracket mounting component 7, which passes through the flexible sheath 1 and is fixed to the corresponding installation position on the vehicle body. Specifically, the bracket mounting component 7 is a bolt, which is rectangularly distributed on the bracket 2. After the four bolts are tightened, the flexible sheath 1 is compressed and makes an interference fit with the vehicle body, so that the waterproof structure is interference-fitted with the corresponding position on the vehicle body, thereby achieving a waterproof effect.

[0030] In this embodiment, the waterproof structure includes an edge waterproof strip 10 disposed on the edge of the flexible sheath 1 and extending towards the vehicle body. The edge waterproof strip 10 is disposed on the edge of the flexible sheath 1 and protrudes outward to form a physical barrier. When the bracket mounting component 7 fixes the flexible sheath 1 to the corresponding installation position on the vehicle body, it squeezes the edge waterproof strip 10 to achieve an interference fit between the edge waterproof strip 10 and the vehicle body, which can effectively prevent water vapor or liquid from seeping in.

[0031] In this embodiment, the edge waterproof strip 10 is inclined outward. Specifically, the outward inclination means that the edge waterproof strip 10 is inclined towards the outer periphery of the flexible sheath 1. The inclined setting can increase the contact area between the edge waterproof strip 10 and the vehicle body, and can further improve the waterproof effect when the interference fit is used.

[0032] In this embodiment, the waterproof structure includes an arc-shaped waterproof strip 11 that is provided on the outward arc protrusion of the flexible sheath 1. The arc-shaped waterproof strip 11 is located inside the edge waterproof strip 10. When the bracket mounting component 7 fixes the flexible sheath 1 to the corresponding installation position on the vehicle body, the edge waterproof strip 10 is pressed against the vehicle body to achieve an interference fit, thereby improving the waterproof effect.

[0033] In this embodiment, a sleeve mounting component 8 is provided on the side of the flexible sleeve body 1 that contacts the vehicle body. This mounting component 8 is interference-fitted with the pre-drilled wiring harness hole on the vehicle body. The sleeve mounting component 8 is integrally formed on the flexible sleeve body 1 and conforms to the shape of the pre-drilled wiring harness hole on the vehicle body. The interference fit between the sleeve mounting component 8 and the pre-drilled wiring harness hole on the vehicle body ensures that the rubber sleeve will not fall off during installation and facilitates installation. The head of the sleeve mounting component 8 is provided with a snap-fit ​​part 9. The snap-fit ​​part 9 completely passes through the pre-drilled wiring harness hole on the vehicle body, allowing the sleeve mounting component 8 to snap into the pre-drilled wiring harness hole on the vehicle body, further improving the stability of the installation.

[0034] In this embodiment, the waterproof structure includes a waterproof part 12 disposed at the root of the outer periphery of the sheath mounting part 8. The waterproof part 12 is interference-fitted with the edge of the reserved wiring harness hole of the vehicle body. The waterproof part 12 is a chamfer opened at the root of the outer periphery of the sheath mounting part 8 to form a waterproof barrier. It can also achieve close contact by utilizing the extensibility of the elastic material, effectively preventing water from seeping in.

[0035] In this embodiment, when the bracket 2 is installed at the corresponding installation position on the vehicle body, the edge waterproof strip 10 and the arc-shaped waterproof strip 11 are pressed against the horizontal plane of the vehicle body installation position, and the edge of the reserved wire harness hole of the waterproof part 12 on the vehicle body (the two right-angle sides of the hole) is pressed against it, thus realizing a three-layer waterproof structure and improving the waterproof effect.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
