Description

Technical Field

[0001] This utility model relates to the field of automotive main carpet technology, and in particular to an automotive sound insulation main carpet that facilitates wiring. Background Technology

[0002] In today's society, cars are a common means of transportation, bringing great convenience to human travel. When driving a car, in order to further block noise and vibration from the engine, chassis, and road surface, a large area of ​​sound-absorbing carpet is usually laid on the car floor. However, the following problems still exist: In actual use, in order to further enhance the driving experience, audio equipment, large-screen tablets and dashcams are usually added to cars. However, the wiring of the newly added equipment is difficult to hide, which can easily lead to a messy wiring layout, greatly reducing the aesthetics of the interior. In addition, the messy wiring layout can easily damage the wiring during use, and it is also difficult to sort out the wiring during later maintenance, increasing the maintenance difficulty. Therefore, a car soundproofing main carpet that facilitates wiring is proposed. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of existing technologies where it is difficult to hide the wiring of added equipment and the layout is messy, and to propose a car sound insulation main carpet that facilitates wiring.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A car soundproofing main carpet with convenient wiring includes a rubber pad, the top perimeter of which is integrally formed with wiring. The wiring mechanism includes an Ω-shaped groove on the top of the wiring line, and multiple equally spaced square grooves on the top of the wiring line. The top of the Ω-shaped groove has an arc-shaped opening, and the wiring line is made of flexible and deformable rubber. The arc-shaped opening is smaller than the width of the wire harness in its natural state. When the wire harness is pressed into the Ω-shaped groove, the arc-shaped opening can expand elastically to facilitate the wire harness entering the Ω-shaped groove.

[0005] In one possible design, the top of the rubber pad is fixedly connected with multiple anti-slip protrusions and multiple equidistant anti-slip strips.

[0006] In one possible design, a sound-absorbing pad is adhered to the bottom of the rubber pad.

[0007] In one possible design, the sound insulation pad consists of polyester fleece, EVA, PE film, and needled cotton, which are bonded and fixed together from top to bottom.

[0008] In one possible design, multiple damping struts are bonded to the bottom of the sound insulation pad.

[0009] In one possible design, the square slot is connected to the Ω-shaped slot.

[0010] In this application: When wiring harnesses need to be laid, simply align the harness with the arc-shaped opening of the Ω-shaped groove on the wiring harness and press down. Since the wiring harness is made of flexible and deformable rubber, the applied pressure will cause the arc-shaped opening to expand elastically, allowing the harness to enter the Ω-shaped groove. The arc-shaped opening is rounded, which facilitates the entry and exit of the harness and is not easy to scratch the surface of the harness. When the pressure is released, the arc-shaped opening retracts to its natural state. Its opening size is smaller than the diameter of the harness, which effectively prevents it from coming loose during vehicle vibration. For the branch joints or ends of the harness, it can be embedded or passed through the nearest square groove. The square groove provides a limit, making the harness layout neater and more orderly. The rubber pad itself has a certain mass and damping characteristics, which can effectively absorb and isolate some mid-to-high frequency noise. The composite structure sound insulation pad has good sound insulation and shock absorption performance through multiple layers of materials, including polyester fleece and EVA layer, which can further block the transmission of noise. The PE film forms a reliable waterproof barrier to prevent chassis moisture from corroding the carpet and wiring harness. The bottom layer of needle-like cotton provides soft support to ensure that the carpet fits tightly with the body sheet metal and eliminates gaps that may cause abnormal noise.

[0011] Beneficial effects: In this utility model, the car sound insulation main carpet that facilitates wiring uses components such as Ω-shaped grooves, arc-shaped openings, wiring lines, and square grooves in combination. The pressure applied to the wiring harness causes the arc-shaped opening to expand elastically, sending the wiring harness into the Ω-shaped groove for fixation. This makes the wiring harness hidden and fixed in the Ω-shaped groove, resulting in a neater and more orderly wiring harness layout. It also effectively protects the wiring harness from damage and improves the service life of the wiring harness. In this utility model, the car sound insulation main carpet that facilitates wiring uses a combination of components such as Ω-shaped grooves, arc-shaped openings, wiring lines, and square grooves. For branch joints or both ends of the wiring harness, the wires can be embedded or passed through the nearest square groove. The square groove provides a limit, making the wiring harness more orderly, facilitating later maintenance, and making it easier to replace the wiring harness. In this invention, the pressure applied to the wire harness causes the arc-shaped opening to expand elastically, feeding the wire harness into the Ω-shaped groove for fixation. This makes the wire harness layout neater and more orderly, effectively protects the wire harness from damage, and improves the service life of the wire harness. Attached Figure Description
