Description

Technical Field

[0001] The utility model belongs to the technical field of automobile wire speed protection, and in particular relates to a noise-reducing and wear-resistant automobile wire harness protective cover. Background Art

[0002] The automotive wiring harness is the network body of the automotive circuit. Without the wiring harness, there would be no automotive circuit. Due to the importance of the automotive wiring harness, it is generally necessary to ensure the safety and durability of the automotive wiring harness during subsequent use as much as possible during its production. Due to the complex internal structure of the car, the automotive wiring harness needs to be distributed inside the car. For some empty and simple spaces, the automotive wiring harness can be safely used for a long time after installation and fixation. However, after long-term use, the line speed will be severely worn, which will cause the line to be damaged and disconnected. Therefore, it is necessary to protect the automotive wiring harness. The commonly used protection structure of the existing automotive wiring harness is just a layer of cortical protective layer wrapped around the outside of the wiring harness. When it is squeezed and worn for a long time, the cortical protective layer is easy to wear and break. Therefore, the wiring harness is also easily damaged. Moreover, when the wiring harness is in use, the relative movement between the wiring harness and the protective leather tube often produces friction sound, which will bring a bad experience to the car owner. Therefore, the existing automotive wiring harness protective cover generates a large noise when in use and has a short service life due to wear and other reasons. Utility Model Content

[0003] In order to solve the technical problem that the existing automobile wiring harness protective cover is easy to wear and produces a large noise, the utility model provides a noise-reducing and wear-resistant automobile wiring harness protective cover, including an outer bellows, a first clamping joint is provided at the left end of the outer bellows, and a second clamping joint is provided at the right end of the outer bellows. The first clamping joint and the second clamping joint are adapted to the wire outlet hole of the automobile body, and the first clamping joint and the second clamping joint can be detachably clamped on the automobile body. An outer connecting pipe is provided between the first clamping joint and the second clamping joint and the outer bellows, an inner bellows is provided inside the outer bellows, and inner connecting pipes are provided at both ends of the inner bellows, and a plurality of support rods for fixed support are provided between the inner connecting pipe and the outer connecting pipe, and the support rods play a supporting role, and the gaps between the support rods can allow heat to dissipate. Silencing cotton is filled between the outer bellows and the inner bellows, and the silencer cotton plays a role in reducing noise. The silencer cotton is made of polyester fiber sound-absorbing cotton.

[0004] Preferably, the support rods are evenly spaced apart.

[0005] Preferably, the wave distance of the outer bellows is 10≤t≤20 mm.

[0006] Preferably, the wave distance of the inner bellows is 20≤t≤30 mm.

[0007] Preferably, both the outer bellows and the inner bellows are made of nylon material.

[0008] The above solution has the following advantages:

[0009] The setting of the outer bellows and the inner bellows can enhance the service life of the wiring harness protective cover. When the outer bellows is worn, the inner bellows can still protect the automobile wiring harness; the setting of the first clamping connector and the second clamping connector both play a role of clamping and fixing; the setting of the sound-absorbing cotton can reduce noise.
