Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
A door pencil protector for narrow and small space, as shown in fig. 1-3, door panel beating hole 1 and automobile body panel beating hole 2 of car are connected respectively at both ends for the protection passes door panel beating hole 1 with the pencil 3 in automobile body panel beating hole 2, as shown in fig. 1, include: a rubber tube 4 having a passage for accommodating a wire harness, including a first end 41, a protective section 43, and a second end 42 connected in this order; the first sealing piece 5 is connected with the first end 41 and is in interference fit with the door sheet metal hole 1; a second sealing member 6 connected with the second end 42 and in interference fit with the sheet metal hole 2 of the vehicle body; the middle of the protective section 43 is at least partially constructed as a corrugated pipe structure 7, and the plane of the wave crest 71 of the corrugated pipe structure 7 and the axial extending direction of the protective section 43 form an included angle which is 30-85 degrees.
The first sealing piece 5 and the second sealing piece 6 are respectively connected with the door sheet metal hole 1 on the door and the body sheet metal hole 2 on the body, play a sealing role and prevent dust or water vapor from entering the inside of the door or the inside of the body. The first end 41 of the rubber tube 4 is connected with the first sealing element 5, the second end 42 is connected with the second sealing element 6, and the wire harness 3 passes through the rubber tube 4 to realize electric transmission and electric signal transmission of the vehicle body and the vehicle door internal devices. At least part of the protective section 43 is a bellows structure 7, and the bellows structure 7 can increase the protective capability of the rubber tube 4 to the wire harness 3 and can also increase the elasticity so as to be easy to keep flexibility in the process of opening and closing the door. The height of the wave crest 71 in the corrugated pipe structure 7 is increased by making the corrugated pipe structure 7 and the rubber pipe 4 have a certain angle, namely the thickness of the corrugated pipe structure 7 can be increased, so that the fatigue resistance of the rubber pipe 4 is increased, and the service life of the rubber pipe is prolonged. Experiments prove that when the included angle between the plane of the peak 71 and the axial extending direction of the protection section 43 is smaller, the larger the cross-sectional area of the plane of the peak 71 is, the better the protection of the wire harness 3 can be provided. If the angle between the plane of the peak 71 and the axial extending direction of the protecting section 43 is greater than 85 °, the cross-sectional area of the plane of the peak 71 is not significantly increased, and if the angle between the plane of the peak 71 and the axial extending direction of the protecting section 43 is less than 30 °, the support of the protecting section 43 by the bellows is not significantly increased, so that the inventors preferably have an angle of 30 ° -85 °.
Further, the protecting section 43 is integrally formed with the bellows structure 7. The integrally formed design is not only convenient to process, but also increases stability to prevent the bellows 7 from falling off the protective section 43.
Further, the protecting section 43 is integrally formed with the first end 41 and the second end 42. The rubber tube 4 integrated into one piece's design can reduce the link of connecting, further increases leakproofness and stability.

In some embodiments, the rubber tube 4 is made of ethylene propylene diene monomer rubber. The ethylene propylene diene monomer rubber has low density, good ageing resistance, corrosion resistance, steam resistance, overheat resistance, elasticity and adhesiveness, and the rubber tube manufactured by the ethylene propylene diene monomer rubber is suitable for ensuring enough elasticity and damage resistance between a vehicle door sheet metal and a vehicle body sheet metal.
In some embodiments, the bellows structure 7 has a length of at least 50% of the length of the guard section 43. If the length of the bellows structure 7 is too short, it is difficult to achieve a sufficient protection, and when the length of the bellows structure 7 is at least 50% of the length of the protection section, the requirements of more vehicle types on the rubber member can be satisfied.
In some embodiments, the first end 41 is disposed at a spatial angle to the second end 42. In order to adapt to the installation environments of different vehicle types, in practical design, the first end 41 and the second end 41 have a space included angle to meet the requirements of vehicle doors with various orientations.
In some embodiments, the connection between the first end 41 and the protection section 43 and the connection between the second end 42 and the protection section 43 are both provided with a reinforcement portion 44. In the process of opening and closing the vehicle door, the connection part between the first end 41 and the protection section 43 and the connection part between the second end 42 and the protection section 43 can be repeatedly bent, and the reinforcing part is added at the connection part, so that the strength of the rubber tube 4 can be effectively increased, and the service life is prolonged.
The utility model also provides a door harness protection structure for a narrow space, which comprises the harness 3 and the door harness protection piece for the narrow space, wherein the harness 3 passes through the rubber tube 4, and the harness 3 is in sealing connection with the first end 41 and the second end 42. The wire harness 3 is in sealing connection with the first end 41 and the second end 42, so that dust or water vapor can be prevented from entering the rubber tube 4, and the purpose of protecting the wire harness 3 is achieved.
Further, the wire harness 3 includes a bent section, which is located inside the rubber tube 4. In the process of opening and closing the door, the rubber tube 4 deforms and the wire harness 3 stretches, enough bending sections remain in the rubber tube 4 to provide stretching allowance for the wire harness 3, and the wire harness 3 is prevented from breaking when the door is opened to the limit position.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the utility model.
