Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness tape technology, and in particular to an automotive wiring harness tape with noise reduction properties. Background Technology

[0002] The rapid development of the automotive industry has placed unprecedented demands on vehicle comfort and quietness. Among the many factors affecting the driving experience, the noise, vibration, and harshness performance of the vehicle's interior are particularly critical. In particular, abnormal noises caused by automotive wiring harnesses have become a significant NVH (Noise, Vibration, and Harshness) issue. Automotive wiring harnesses are the "nerve and vascular system" of a vehicle, and the reliability of their fixation and protection directly affects the safety and comfort of the entire vehicle. Currently, the automotive manufacturing industry commonly uses tape to wrap, bundle, and fix wiring harnesses. Its main functions are bundling wires, providing insulation protection, wear and corrosion resistance, and marking areas. In general, automotive wiring harness tape offers the following benefits: Bundling and securing: It bundles disparate wires into a sturdy harness, facilitating wiring, installation, and fixation within the vehicle. Insulation protection: It prevents short circuits between wires and provides basic electrical insulation. Abrasion resistance: It protects the wiring harness sheath from wear when passing through metal holes or rubbing against other components, preventing risks such as short circuits due to insulation damage. Environmental resistance: It possesses certain properties such as high-temperature resistance, low-temperature resistance, moisture resistance, and flame retardancy to adapt to harsh automotive working environments. Identification: Different colored tapes facilitate identification during production line assembly and after-sales maintenance.

[0003] Existing automotive wiring harness tapes lack effective noise reduction structures. During vehicle operation, due to engine running, road bumps, and torsional deformation of the vehicle body, the wiring harness is continuously subjected to broadband vibrations and impacts. This vibration causes the tape-bound wiring harness, as a whole, to continuously collide, rub, and move relative to the surrounding body panels, brackets, or other wiring harnesses, producing unpleasant "clicking" and "squeaking" noises across a wide frequency range. This continuous noise can severely affect the driver's mood. Furthermore, the inability to effectively suppress or reduce noise will affect driving safety, making drivers more susceptible to distraction and creating significant safety hazards. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automotive wiring harness tape with noise reduction properties includes a main body comprising a base adhesive layer, a damping constraint layer, and a friction optimization layer.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example

[0020] A type of automotive wiring harness tape with noise reduction properties, such as Figure 1-2 As shown, the device includes an automotive wiring harness tape body 1. The automotive wiring harness tape body 1 includes a base adhesive layer 101, a damping constraint layer 102, and a friction optimization layer 103. The damping constraint layer 102 is disposed on one side of the fixed shaft 10, and one side of the damping constraint layer 102 is attached to the base adhesive layer 101. The damping constraint layer 102 is bonded and fixed to the base adhesive layer 101. The friction optimization layer 103 is disposed on one side of the damping constraint layer 102, and one side of the friction optimization layer 103 is attached to the damping constraint layer 102. The friction optimization layer 103 is bonded and fixed to the damping constraint layer 102. Several sets of grooves are formed at the bottom of the base adhesive layer 101. The grooves are serrated in shape. The damping constraint layer 102 is a three-layer composite structure. In use, the automotive wiring harness tape body 1 is formed by combining the base adhesive layer 101, the damping constraint layer 102, and the friction optimization layer 103. The automotive wiring harness tape body 1 is then evenly wrapped around the automotive wiring harness for arrangement and fixation. The damping constraint layer 102 is located between the friction optimization layer 103 and the base adhesive layer 101. The base adhesive layer 101 is made of medium-tack acrylic foam adhesive. This layer is the core shock-absorbing layer; its soft foam structure absorbs and disperses the impact energy at the contact points between the wiring harness and the vehicle body, preventing hard contact. Simultaneously, it firmly adheres to the wiring harness surface, but its softness prevents stress on the wiring harness due to excessive tightness. Several sets of serrated grooves at the bottom of the base adhesive layer 101 increase the bonding strength, making the adhesion more secure and preventing accidental detachment that could cause the automotive wiring harness to unravel. The damping constraint layer 102 is a three-layer composite structure. The first and third layers are made of high-damping soft PVC material, while the middle layer is made of… The material is an asphalt-based damping film, which can form a sandwich-like structure. It can quickly convert the mechanical energy of vibration transmitted from the wiring harness into heat energy through molecular friction within the material, thereby suppressing the generation and propagation of vibration from the source. The friction optimization layer 103 is made of non-woven fabric. The outer surface of this layer provides a good coefficient of friction. When in contact with the car body or other parts, it can prevent easy slippage and avoid high-frequency friction noise that may be caused by rough surfaces. The flocked surface can achieve extremely low sliding noise. The combination of the base bonding layer 101, damping constraint layer 102 and friction optimization layer 103 can effectively reduce noise and suppress vibration when fixing the automotive wiring harness. By suppressing the generation of vibration, the generation of noise can be reduced from the source. The friction optimization layer 103 can effectively reduce noise and avoid high-frequency friction noise, which can increase safety when driving and avoid the continuous noise from affecting the driver's mood. At the same time, it can also avoid the situation where the driver is distracted by noise and cause accidents. To enhance the noise reduction effect, such as Figure 2 As shown, the friction optimization layer 103 has several sets of sound-absorbing holes arranged in sequence, and the sound-absorbing holes are hexagonal in shape; When in use, noise reduction can be further achieved by opening several sets of hexagonal sound-absorbing holes on the friction optimization layer 103. When sound waves are introduced, air molecules will rub against each other in the sound-absorbing holes, thereby converting sound energy, especially mid-to-high frequency noise, into heat energy, which plays an effective role in noise reduction. In order to protect, such as Figure 1 , 2 As shown, a protective layer 2 is provided on one side of the main body 1 of the automotive wiring harness tape, and the surface of the protective layer 2 is coated with a wear-resistant coating. When in use, the protective layer 2 is made of PU material, which has good wear resistance. By spraying a wear-resistant coating, the wear resistance and aesthetics can be increased, thereby effectively extending the service life and preventing breakage and cracking. To facilitate the winding of the automotive wiring harness tape body 1, such as Figure 3 , 4 As shown in Figure 5, a protective shell 3 is provided on one side of the main body 1 of the automotive wiring harness tape, and a discharge port is provided on one side of the protective shell 3. The size and position of the main body 1 of the automotive wiring harness tape are adapted to the discharge port. A fixed shaft 10 is rotatably installed on the inner wall of the protective shell 3. A winding wheel 13 is provided on the fixed shaft 10. The winding wheel 13 is arranged in a circle and has several sets of anti-slip protrusions. When in use, one end of the automotive wiring harness tape body 1 can be wound around the take-up reel 13. After winding around the take-up reel 13, the automotive wiring harness tape body 1 can be protected by the protective shell 3 to prevent aging caused by environmental factors, which would affect normal use. At the same time, it can prevent impurities from entering and affecting the bonding effect. The automotive wiring harness tape body 1 can be wound up by rotating the fixed shaft 10. When the automotive wiring harness tape body 1 is needed, pull the automotive wiring harness tape body 1 to pull it out from the discharge port for normal use. The take-up reel 13, which is equipped with several sets of anti-slip protrusions, can prevent the automotive wiring harness tape body 1 from slipping and falling off during winding. In order to cut the main body 1 of the automotive wiring harness tape, such as Figure 3 , 4 As shown, a guide slide 9 is provided on one side of the protective shell 3, and a movable frame 8 is slidably provided through the guide slide 9. A connecting frame 7 is provided on one side of the movable frame 8, and a cutting blade 6 is provided at the bottom of the movable frame 8. When in use, the size and position of the cutting blade 6 are adapted to the discharge port of the protective shell 3. When the automotive wiring harness tape body 1 is pulled out for use, the connecting frame 7 can be controlled to move down after being pulled out to the required length. The moving frame 8 and the cutting blade 6 are moved down synchronously by the moving frame 7. The cutting blade 6 can cut the automotive wiring harness tape body 1 by moving down, so that the automotive wiring harness tape body 1 can be cut quickly for use. The movement trajectory of the cutting blade 6 can be restricted by the moving frame 8 sliding on the guide slide 9. To facilitate control of the rotation of the fixed shaft 10, such as Figure 3 , 5 As shown, a slot is provided on one side of the fixed shaft 10, a handle 5 is provided on one side of the fixed shaft 10, and a block 12 is provided on one side of the handle 5. The size and position of the block 12 are adapted to the slot. When in use, the locking block 12 at one end of the throttle 5 can be inserted into the slot at the end of the fixed shaft 10. After insertion, the connection between the throttle 5 and the fixed shaft 10 can be completed. After connection, the throttle 5 can be controlled to rotate, thereby synchronously controlling the rotation of the fixed shaft 10 and the winding wheel 13 to wind and extend the automotive wiring harness tape body 1. The throttle 5 makes it easier and more convenient to control the rotation of the fixed shaft 10. To prevent the throttle from falling off, such as Figure 4 ,5 As shown, a groove is provided at the end of the fixed shaft 10, and a magnetic block 11 is embedded in the groove. A magnetic sheet is embedded in the block 12. When using the throttle 5, the locking block 12 at the end of the throttle 5 is inserted into the slot for connection. The magnetic sheet and the magnetic block 11 attract each other to reinforce the throttle 5, which can prevent the throttle 5 from falling off accidentally during use. Example

This embodiment makes the following improvements compared to embodiment 1: a transparent observation window 4 is provided on one side of the protective shell 3, and the observation window 4 is made of acrylic material. During use, the remaining amount of automotive wiring harness tape 1 inside the protective shell 3 can be easily observed through the transparent acrylic observation window 4, allowing for timely monitoring of the remaining amount of automotive wiring harness tape 1 and preventing insufficient automotive wiring harness tape 1 during use.
