[0001] This utility model relates to the field of automotive parts technology, and in particular to a bending wire harness protection device. Background Technology

[0002] In traditional automotive design, wiring harnesses are typically bundled and secured with cable ties before being mounted to the vehicle body. However, due to limitations in vehicle body strength and surrounding components, it's often impossible to design a structure for mounting the wiring harness at the designated mounting points, leading to interference between harnesses or situations where the harnesses are suspended in mid-air. This design is not only aesthetically unpleasing but also has low reliability, making it susceptible to external interference and even vulnerable to being chewed through by rodents, causing serious safety issues. With the development of the automotive industry, especially the emergence of electric and hybrid vehicles, the number of high-voltage wiring harnesses has increased significantly, making the need for wiring harness protection even more urgent. Existing wiring harness protection boxes mostly use an upper and lower cover structure, fixed to the vehicle body by clips or bolts.

[0003] For example, CN203326512U, published on December 4, 2013, discloses a vehicle wiring harness protection box, including a main channel cavity that matches the profile of the center channel. The side wall of the main channel cavity also has a wiring harness branch channel communicating with the main channel cavity; the side wall of the main channel cavity has multiple mounting brackets for fixing. The aforementioned wiring harness protection box cannot be stably connected to the A-pillar of a car, thus failing to provide stable protection for the wiring harness on the A-pillar side.

The side wall of the housing 1 is provided with a wire harness connector 4 and a video cable connector 5. In this embodiment, there are two wire harness connectors 4 and two video cable connectors 5, and the wire harness connectors 4 and the video cable connectors 5 are located on the same side of the side wall of the housing 1.

[0023] In use, the box 1 is installed at the A-pillar of the car. The shape of the box 1 is adapted to the A-pillar of the car, thus ensuring the stable installation of the box 1 on the A-pillar of the car. The wire harness inside the car passes through the channel 2 in the box 1. The cable tie passes through the cable tie fixing hole 3 in the channel 2 to fix the wire harness stably in the channel 2. The wire harness is connected to the wire harness connector 4 and the video cable connector 5 on the side wall of the box 1, thus realizing the connection of the wire harness. The box 1 protects the wire harness and prevents the wire harness from being worn due to vibration during vehicle operation or chemical corrosion, thus extending the service life of the wire harness and ensuring the stable operation of the wire harness.

[0024] The box 1 includes a base plate 101 and side plates 102 disposed on both sides of the base plate 101. The base plate 101 and the side plates 102 are integrally molded parts. The box 1 has a U-shaped cross-section, and the channel 2 is disposed between the two side plates 102. The U-shaped box 1 protects the wiring harness and facilitates the connection of the box 1 to the A-pillar of the car, thereby achieving stable installation of the box 1. Specifically, the base plate 101 and the side plates 102 are integrally injection molded, thereby increasing the strength of the entire box 1 and increasing the service life of the box 1, thus achieving stable protection of the wiring harness on the A-pillar of the car.

[0025] Box 1 is L-shaped to ensure that it matches the shape of the car's A-pillar, thus ensuring accurate installation of box 1 on the car and providing precise protection for the wiring harness.

[0026] The wire harness connector 4 and the video cable connector 5 are mounted on the side plate 102.
