Description

Technical Field

[0001] This utility model relates to the field of wire harness fixing technology, and in particular to an automotive wire harness fixing bracket. Background Technology

[0002] In the automotive manufacturing industry, the secure fixing of wiring harnesses is crucial. Traditional wiring harness fixing mostly uses disposable cable ties or pipe clamps. However, disposable cable ties are inconvenient to remove and have poor stability. After prolonged use, the cable ties may deform, break, or fall off due to vibration, leading to wire harness displacement and wear. Pipe clamps can only restrict the wire harness from large movements, but pipe clamps are generally larger than the wire harness, allowing the harness to wobble inside the clamp. Over time, this can cause wire harness wear and affect the normal operation of the vehicle's electrical system. Furthermore, existing new energy vehicles have a large number of wiring harnesses, making it impossible to secure multiple strands of wire harness at once, resulting in a messy wiring harness. Utility Model Content

[0003] To address the aforementioned issues, this invention provides an automotive wiring harness fixing bracket that can simultaneously secure multiple wiring harnesses, effectively preventing harness wear and meeting the usage requirements of automotive electrical systems.

[0004] Therefore, the technical solution of this utility model is: an automotive wiring harness fixing bracket, including a metal bracket and a protective sleeve. The metal bracket is provided with at least two longitudinally stacked C-shaped fixing parts. The bottom of the metal bracket extends into a mounting surface, which is provided with mounting holes and anti-rotation hooks at the edge of the mounting surface. A protective sleeve is provided inside each C-shaped fixing part, and the protective sleeve has an axially penetrating opening groove on the side away from the C-shaped fixing part. A strap is fixed to the upper end of the protective sleeve, and the free end of the strap is provided with Velcro. The bottom mounting surface of the metal bracket and the common surface of the two adjacent C-shaped fixing parts are provided with strap through holes for the strap to pass through.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: a short rod is provided in the middle of the strap through hole, the free end of the strap is inserted into the strap through hole, and passes around the short rod from below and then comes out, and the free end of the strap is fixed to the strap itself by Velcro.

[0006] Based on the above solution and as a preferred embodiment of the above solution: the protective sleeve is made of rubber, and the inner wall of the protective sleeve is provided with a fleece layer.

[0007] Based on the above solution and as a preferred solution: the metal bracket is provided with an L-shaped hook, which is located on the back of the uppermost C-shaped fixing part.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the protective sleeve has limiting protrusions at both ends, which work in conjunction with the C-shaped fixing part.

[0009] Based on the above solution and as a preferred solution: the protective sleeve is provided with a strip magnet embedded on the side facing the C-shaped fixing part, and is fixed to the C-shaped fixing part by magnetic attraction.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention, by setting at least two vertically stacked C-shaped fixing parts, can simultaneously fix multiple wire harnesses, effectively solving the problem of existing new energy vehicles having a large number of wire harnesses and being unable to fix multiple wire harnesses at once, resulting in messy wire harnesses. This makes the layout of the wire harnesses inside the vehicle more orderly and facilitates the management and maintenance of the wire harnesses.

[0012] This invention uses a cable tie with Velcro to secure the wiring harness, which is more convenient to remove than disposable cable ties. When adjustment or repair of the wiring harness is needed, the Velcro can be easily unfastened, making operation convenient. Furthermore, the design of the cable tie's perforation and short rod allows the free end of the cable tie to pass through the perforation, wrap around the short rod, and then exit before being secured to itself with Velcro. This method enhances the stability of the cable tie, preventing it from loosening or shifting due to vehicle vibration, ensuring the wiring harness remains in a stable, fixed state.

[0013] The protective sleeve of this utility model is made of rubber, which has good flexibility and cushioning performance, and can reduce the impact of external factors on the wiring harness. The fluff layer on the inner wall further reduces the friction between the wiring harness and the protective sleeve, preventing the wiring harness from wearing out due to long-term friction, effectively protecting the outer sheath of the wiring harness, extending the service life of the wiring harness, and ensuring the normal operation of the automotive electrical system.

[0014] This utility model features an anti-rotation hook at the edge of the mounting surface at the bottom of the metal bracket, which can tightly engage with the mounting surface to effectively prevent the bracket from rotating due to vibration during vehicle operation. At the same time, an L-shaped hook is provided on the back of the metal bracket to ensure that the entire wire harness fixing bracket is installed more firmly, maintain the fixed position of the wire harness, and further ensure the safety and stability of the wire harness.

[0015] This invention features a strip magnet embedded in the side of the protective sleeve facing the C-shaped fixing part, which is magnetically fixed to the C-shaped fixing part. This makes it easier and faster to install the protective sleeve into the C-shaped fixing part without the need for additional installation tools or complicated installation steps, thereby improving the assembly efficiency of the wire harness fixing bracket and reducing installation costs.

[0025] Example 1

[0026] The automotive wiring harness fixing bracket described in this embodiment includes a metal bracket 1 and a protective sleeve 2. The metal bracket 1 has two longitudinally stacked C-shaped fixing parts 11. A mounting surface 12 extends from the bottom of the metal bracket 1, and the mounting surface 12 has mounting holes 13. An anti-rotation hook 14 is provided at the edge of the mounting surface 12. The metal bracket 1 has an L-shaped hook 15, which is located on the back of the uppermost C-shaped fixing part 11. The L-shaped hook 15 can be hung on the automotive sheet metal part 4, making the metal bracket 1 less prone to tipping over.

[0027] Each C-shaped fixing part 11 is provided with a protective sleeve 2. The protective sleeve 2 has limiting protrusions 21 at both ends, which work together with the C-shaped fixing part 11 to effectively prevent the protective sleeve 2 from axial displacement. At the same time, in order to better fix the protective sleeve 2, a bar magnet is embedded on the side of the protective sleeve 2 facing the C-shaped fixing part 11 (the bar magnet is located on the opposite side of the opening slot and will not interfere with the opening and closing of the protective sleeve). It is magnetically fixed to the C-shaped fixing part 11 of the metal bracket 1, and the material of the metal bracket 1 can be attracted by the magnet.

[0028] The protective sleeve 2 is made of rubber, and the inner wall of the protective sleeve 2 is provided with a fleece layer 22, which can reduce the friction between the wire harness 5 and the protective sleeve 2 and prevent the wire harness 5 from being worn due to long-term friction. The protective sleeve 2 has an axially through opening groove 23 on the side away from the C-shaped fixing part 11, which facilitates the insertion of the wire harness 5.

[0029] The upper end of the protective sleeve 2 is fixed with a strap 3, and the free end of the strap 3 is provided with a Velcro 31. The bottom mounting surface 12 of the metal bracket 1 and the common surface 16 of the two adjacent C-shaped fixing parts 11 are provided with strap holes 17 for the strap to pass through. A short rod 18 is provided in the middle of the strap hole 17. The free end of the strap 3 passes through the strap hole 17, goes around the short rod 18 and then comes out. The free end of the strap 3 is fixed to the strap itself by the Velcro 31. The size of the opening slot of the protective sleeve 2 can be reduced by the strap 3, so that the protective sleeve 2 fits the wire harness 5 more closely.

[0030] This embodiment is suitable for installation in areas with limited space and available space in the vertical direction, such as under car seats or other locations with limited space but some leeway in the vertical direction. The wiring harness can be arranged in this vertical manner, which can effectively utilize the vertical space inside the car, making the wiring harness layout more compact, avoiding the wiring harness from being squeezed against each other in a limited space, and reducing the risk of wiring harness damage.

[0031] Example 2

[0032] The automotive wiring harness fixing bracket described in this embodiment includes a metal bracket 1 and a protective sleeve 2. The metal bracket 1 has three longitudinally stacked C-shaped fixing parts 11, and the rest of the structure is similar to that of Embodiment 1. This embodiment can be applied to scenarios with more wiring harnesses, stacking and fixing three wire harnesses to make the wiring harness layout more compact.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
