Description

Technical Field

[0001] This utility model relates to the field of wire harness rubber parts technology, specifically a self-locking plastic skeleton rubber part for automotive front bulkhead. Background Technology

[0002] Wiring harness rubber parts refer to elastic rubber components used at the perforations in automotive sheet metal to provide good protection and smooth transitions during the process of wiring harnesses passing through or being assembled into sheet metal. Because the engine (electric motor) in the front engine compartment generates noise during operation, and a quiet cabin is required, the wiring harness in the front engine compartment passes through corresponding perforations in the sheet metal. Therefore, the rubber parts at these perforations must protect the engine compartment wiring harness while also providing sound insulation and noise reduction. In traditional designs of perforated rubber parts, this sound insulation and noise reduction is achieved by increasing the thickness of the external structure. However, this traditional design has a drawback: the large external thickness results in a heavy product, higher cost, and more time-consuming and labor-intensive installation, with less than ideal sound insulation and noise reduction performance.

[0008] Preferably, the rubber component adapter structure on the self-locking rubber skeleton corresponds one-to-one with the skeleton adapter on the sealing end rubber component.

[0009] Preferably, a sealing ring is provided inside the self-locking rubber skeleton.

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

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] Please see Figure 1 , Figure 2 and Figure 3 A self-locking plastic skeleton rubber component for automotive front bulkhead includes a silent end rubber component 1. The lower end of the silent end rubber component 1 is connected to two symmetrically arranged self-locking rubber skeletons 2, which are interconnected. The lower end of the silent end rubber component 1 is secured with a sealing end rubber component 3. The two self-locking rubber skeletons 2 are self-locking and self-assembled, and then the silent end rubber component 1 is assembled onto the assembled self-locking rubber skeleton 2. Finally, the sealing end rubber component 3 is assembled together to form a combined rubber component consisting of four parts. This combined rubber component is then assembled onto the flanged sheet metal opening in the front engine compartment of the vehicle. This product solves the problem of difficult assembly of traditional rubber components in environments with limited space in the front engine compartment. The combined rubber component provides protection for wiring harnesses, separation of dry and wet areas, sealing, superior installation performance, and sound insulation and noise reduction in its functional area.

[0020] Please see Figure 1 , Figure 2 and Figure 3The silent end rubber component 1 includes a flexible corrugated structure 102. By setting the flexible corrugated structure 102 on the silent end rubber component 1, the cabin wiring harness can achieve a flexible exit effect after passing through the silent end rubber component 1. The upper end of the flexible corrugated structure 102 is provided with a wiring harness adapter structure 101, and the lower end of the flexible corrugated structure 102 is provided with a cavity sound insulation structure 103. By setting the cavity sound insulation structure 103, the cavity structure can achieve a sound insulation and noise reduction effect, reducing noise during the propagation of noise. The lower end of the cavity sound insulation structure 103 is provided with an outwardly bent edge, and a skeleton adapter structure 104 is provided on the bent edge.

[0021] Please see Figure 2 , Figure 3 and Figure 4 The self-locking rubber skeleton 2 is arc-shaped. One end of the self-locking rubber skeleton 2 is fixed with a self-locking fixing structure 204. Limiting guide structures 203, which are fixedly connected to the self-locking rubber skeleton 2, are respectively provided on the upper and lower sides of the self-locking fixing structure 204. The other end of the self-locking rubber skeleton 2 is provided with a guide hole corresponding to the limiting guide structure 203 and a snap-fit ​​interface corresponding to the self-locking fixing structure 204. The self-locking fixing structure 204 on the self-locking rubber skeleton 2 snaps into place with the snap-fit ​​interface on the other self-locking rubber skeleton 2, completing the mutual docking and snapping of the two self-locking rubber skeletons 2. Simultaneously, the limiting guide structure 203 on the self-locking rubber skeleton 2 corresponds to the guide hole on the other self-locking rubber skeleton 2, facilitating the quick docking of the two self-locking rubber skeletons 2. The self-locking rubber skeleton 2 has several flanged sheet metal hole adapter structures 201 on its outer side. The flanged sheet metal hole adapter structures 201 overlap the skeleton adapter structure 104. The lower end of the self-locking rubber skeleton 2 has a folded edge, on which a rubber component adapter structure 202 is provided. The rubber component adapter structure 202 corresponds one-to-one with the skeleton adapter 303 on the sealing end rubber component 3, ensuring the connection between the sealing end rubber component 3 and the self-locking rubber skeleton 2. The self-locking rubber skeleton 2 has a sealing ring 205 inside. After two self-locking rubber skeletons 2 are connected to each other, the sealing ring 205 on the self-locking rubber skeleton 2 will tightly fit against the outer side of the cavity sound insulation structure 103, thereby achieving a seal and ensuring the sealing performance between the silent end rubber component 1 and the self-locking rubber skeleton 2.

[0022] Please see Figure 1 , Figure 2 and Figure 3The sealing end rubber component 3 includes a flexible corrugated component 304. By providing the flexible corrugated component 304 on the sealing end rubber component 3, the cabin wiring harness can achieve a flexible exit effect after passing through the sealing end rubber component 3. A wiring harness adapter 305 is provided at the lower end of the flexible corrugated component 304, and an outer ring sealing rib structure 301 and an inner ring sealing rib structure 302 are provided at the upper end of the flexible corrugated component 304. The outer ring sealing rib structure 301 is located outside the inner ring sealing rib structure 302. The outer ring sealing rib structure 301 and the inner ring sealing rib structure 302 are arc-shaped and tilt outward from bottom to top. By providing the outer ring sealing rib structure 301 and the inner ring sealing rib structure 302, a flexible exit effect can be achieved. The sealing rib structure 302 has high sealing strength and can better achieve dry and wet area separation. At the same time, the outer sealing rib structure 301 and the inner sealing rib structure 302 are set at an angle. After the outer sealing rib structure 301 and the inner sealing rib structure 302 come into contact with the body sheet metal and are squeezed, they form a suction cup-like property. The device is fixed to the body sheet metal for further sealing and achieve the effect of dry and wet area separation. The lower end of the outer sealing rib structure 301 and the inner sealing rib structure 302 is provided with several skeleton adapters 303. The rubber adapter structure 202 on the self-locking rubber skeleton 2 corresponds one-to-one with the skeleton adapter 303 on the sealing end rubber part 3.

[0023] When using this utility model:

[0024] The first assembly is completed by two self-locking rubber skeletons 2 fastening together. Then, the silent end rubber component 1 is inserted through the middle space of the self-locking rubber skeleton 2, and the skeleton adapter structure 104 is aligned with the corresponding position of the self-locking rubber skeleton 2. The self-locking rubber skeleton 2 and the silent end rubber component 1 are combined to complete the second assembly. Then, the second assembly is inserted into the sealing end rubber component 3. During this process, the adapter anti-misalignment structure of the sealing end rubber component 3 and the self-locking rubber skeleton 2 needs to be aligned one by one to complete the third assembly. This completes the assembly of the self-locking plastic skeleton combined with the rubber component. Completed by self-locking two rubber skeletons 2 and then assembling the silent end rubber component 1 onto the assembled skeleton, and then assembling the sealing end rubber component 3 together, a combined rubber component consisting of 4 products is formed. The combined rubber component is then assembled onto the sheet metal position of the flange opening in the front engine compartment of the car. This product can solve the problem of the difficulty in assembling traditional rubber components in the environment of small assembly space in the front engine compartment. The combined rubber component plays a role in protecting the wiring harness, separating dry and wet areas, sealing, and providing superior installation performance and sound insulation and noise reduction in the functional area.
