[0003] The current rubber sleeves for the front door harnesses of automobiles are not designed to consider the installation environment on the vehicle. The natural shape of the main body of the rubber sleeves when they are not installed is mostly in a straight state, and they have been squeezed after they are installed on the car together with the door harness In the state of pressing or pulling, the rubber sleeve does not play a guiding role for the wire harness, and being squeezed or pulled for a long time not only reduces the life of the rubber sleeve, but also is not conducive to the protection of the wire harness.
[0004] Especially for light trucks or heavy trucks, when the door is opened, the wiring harness and the rubber sleeve just rub against and interfere with the headlight angle plate on the side or under the headlight. If the sealing strip is rubbed off, on the other hand, the rubber sleeve will be worn through by the corner plate of the headlight, which will cause the wiring harness to be directly exposed

Embodiment Construction
[0034] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0035] Such as figure 1 The rubber sleeve for the front door harness of a car shown includes a first connecting part 6, a second connecting part 7 and a telescopic section; firstly, in order to prevent the wiring harness and the rubber sleeve from being squeezed when the door is closed, and the wiring harness and the rubber sleeve when the door is opened Considering that the headlight gusset 4 of some models has a serious impact on the rubber cover when the door is opened, the rubber cover of the present invention no longer adopts a vertical shape when designing, but opens according to the various designs of the car door. degree and any number of calibration angles to simulate the direction of the wiring harness and rubber sleeve.
[0036] The shape of the rubber sleeve completed according to the above design ideas ...

The invention provides a wiring harness rubber sleeve for a front door of an automobile and a design method thereof. The rubber sleeve comprises a first connecting part, a second connecting part and a telescopic segment, wherein the telescopic segment is arranged between the first connecting part and the second connecting part; the first connecting part is connected with a side body metal plate in a matching way; the second connecting part is connected with a door metal plate; the structural parameters of the telescopic segment comprise an obliquely upward degree, a maximum tensile length and a maximum compression length. Through opening of the trends of an angle simulation wiring harness and the rubber sleeve on each design opening and check angle, smooth trend of the wiring harness of the front door at any angle is realized when the door is opened or closed or during opening of the automobile door, and extruding or tensioning of the wiring harness of the front door and the rubber sleeve or friction and interference with other parts is avoided, so that the wiring harness of the front door is protected from being damaged.
Description
technical field [0001] The invention relates to an automobile connecting part, in particular to a rubber sleeve of an automobile front door wiring harness and a design method thereof. Background technique [0002] The wire harness rubber sleeve is a molded rubber product that is coated outside the wire harness and used to protect the wire harness from abrasion when the wire harness passes through the sheet metal. Therefore, the function of the rubber sleeve of the front door harness of the car is to make the door harness between the front door and the side wall of the body reliable, protect the door harness from damage, and prevent water stains and oil stains from entering the interior of the harness. [0003] The current rubber sleeves for the front door harnesses of automobiles are not designed to consider the installation environment on the vehicle. The natural shape of the main body of the rubber sleeves when they are not installed is mostly in a straight state, and they...
