Description

Technical Field

[0001] This utility model relates to the field of tape technology, and in particular to a thick fleece wiring harness tape for automobiles. Background Technology

[0002] Wire harness tape is a material used for the insulation and protection of wires and cables. It is mainly made of polyester fiber (PET) as the base material and coated with pressure-sensitive adhesive. It has the characteristics of high strength, high adhesion, heat resistance, wear resistance and chemical corrosion resistance, and can firmly fix and protect the wire harness, preventing it from loosening or coming apart.

[0003] Fleece-type tape is a type of wire harness tape, typically made with polyester non-woven fleece as the base material, onto which a layer of pressure-sensitive adhesive is coated using a specialized applicator. Its surface is covered with high-quality polyester fleece, offering good flexibility and strength. Fleece-type tape plays a crucial role in the automotive industry for ensuring the safe and stable operation of wire harnesses and enhancing the driving experience.

[0004] A search revealed Chinese patent publication number CN208776638U, which discloses a wire harness tape. The tape body includes a tape base, a double-sided adhesive strip, and an easy-tear strip. The double-sided adhesive strip is positioned on the front of the left end of the tape base and extends along the length of the tape base. The easy-tear strip is positioned on the outer surface of the double-sided adhesive strip. An anti-slip strip is provided on the back of the right end of the tape base. The anti-slip strip has several first anti-slip grooves with a circular cross-section and a shape that is smaller at the top and larger at the bottom. An anti-slip protrusion is provided on the inner wall of the first anti-slip groove, consisting of a first annular boss, a second annular boss, and an annular stop strip. The outer ends of the first and second annular bosses are fixedly connected to the inner wall of the first anti-slip groove. The purpose of this invention is to provide a wire harness tape that provides stable adhesion, prevents separation at the joint, has strong anti-slip properties, and a long service life.

[0005] The aforementioned patent specification mentions that "when using this wire harness tape, the front side is wrapped around multiple wires, the Easy strip is torn open, and the double-sided adhesive strip is pasted onto the anti-slip strip on the back." While this does provide a fixing effect, and the anti-slip strips and grooves enhance the anti-slip effect and prevent the adhesive from separating due to expansion or vibration, the pre-set cuts during the cutting process result in a fixed length of tape. This makes it difficult to effectively adapt to the user's needs when specific length requirements are present. Utility Model Content

[0006] The purpose of this application is to provide a thick fleece wiring harness tape for automobiles, which aims to improve the problem that some tapes in the prior art cannot be effectively cut when special length requirements are needed.

[0007] The thick fleece wiring harness tape for automobiles provided in this application adopts the following technical solution: A thick fleece wiring harness tape for automobiles includes a tape body, an inner lining mechanism provided on the inner wall of the tape body, a cutting mechanism provided on one side of the inner lining mechanism, the cutting mechanism including a mounting shaft, the mounting shaft being rotatably connected to the inside of the inner lining mechanism, a nut being threadedly connected to one side of the mounting shaft, a cutting frame being fixedly connected to the outside of the mounting shaft, and reset components being provided on both sides of the cutting frame. Through the above solution: the thick fleece cable bundle tape has an inner lining mechanism on the inner wall of the tape body, which can support and protect the tape, improving its stability and reliability during use. In the cutting mechanism set on one side, the mounting shaft is externally rotatably connected to the inner lining mechanism, which facilitates the flexible rotation of the cutting mechanism. The nut threaded on one side of the mounting shaft can be quickly installed and disassembled, which is convenient for maintenance and replacement. The cutting frame fixedly connected to the mounting shaft, together with the reset components on both sides, can automatically reset after cutting, improving the convenience and efficiency of cutting.

[0008] As a further description of the above technical solution: The reset assembly includes a fixing plate, with one outer side of the fixing plate fixedly connected to the outer side of the cutting frame. A fixing rod is fixedly connected to the top of the fixing plate, and a sliding outer cylinder is slidably connected to the outside of the fixing rod. A connecting rod is fixedly connected to the top of the sliding outer cylinder, and a spring is provided inside the sliding outer cylinder.

[0009] The above solution involves a fixed plate in the reset assembly, which is fixedly connected to the outside of the cutting frame on one side, ensuring a stable connection between the reset assembly and the cutting frame. The fixed rod fixedly connected to the top of the fixed plate and the sliding outer cylinder slidably connected to the outside form a sliding guide structure, allowing the sliding outer cylinder to slide stably along the fixed rod. The connecting rod fixedly connected to the top of the sliding outer cylinder can be linked with the external structure. The spring inside the sliding outer cylinder generates an elastic reset force after being compressed. When the cutting operation is completed, the spring pushes the sliding outer cylinder downward along the fixed rod through elastic deformation, driving the connecting rod and the cutting frame to reset. This structural design utilizes the elastic potential energy of the spring to achieve automatic reset, ensuring that the cutting frame quickly returns to its initial position after use, thus improving the operational continuity and practicality of the cutting mechanism.

[0010] As a further description of the above technical solution: One end of the spring is fixedly connected to the top of the inner wall of the sliding outer cylinder, and the other end of the spring is fixedly connected to the top of the fixed rod.

[0011] The above solution ensures that the sliding outer cylinder remains under force at both ends as it slides up and down along the fixed rod. When the sliding outer cylinder moves upward, the spring is compressed and accumulates elastic potential energy. When the external force is removed, the spring releases its elastic potential energy to generate a downward thrust, pushing the sliding outer cylinder down along the fixed rod to reset. This connection method with both ends fixed ensures the stable transmission of the spring's elastic force, preventing the spring from shifting or falling off during operation. It also ensures the reliability and stability of the reset component's reset action, allowing the cutting frame to return to its initial position accurately and smoothly after cutting.

[0012] As a further description of the above technical solution: The tape body includes an abrasion-resistant layer, a high-temperature resistant layer on the inner wall of the abrasion-resistant layer, a fleece layer on the inner wall of the high-temperature resistant layer, an insulating layer on the inner wall of the fleece layer, and an adhesive layer on the inner wall of the insulating layer.

[0013] Through the above solution: the tape body adopts a multi-layer structure design. The outermost wear-resistant layer can effectively resist physical damage such as external friction and scratches, extending the service life of the tape. The high-temperature resistant layer on the inner wall of the wear-resistant layer can maintain stable performance in high-temperature environments, preventing the tape from deforming or melting due to high temperatures, ensuring its normal use in the complex temperature environment of automobiles. The soft fleece layer on the inner wall of the high-temperature resistant layer can effectively buffer external impacts, protect the wiring harness from damage, and provide good flexibility for easy tape winding. The insulation layer on the inner wall of the fleece layer can isolate current, avoid safety hazards caused by wire harness leakage, and ensure the safety of the automotive electrical system. The adhesive layer on the inner wall of the insulation layer has good adhesion and can firmly stick to the surface of the wiring harness, ensuring the fixation effect of the tape. The layers work together to improve the tape's protective performance for automotive wiring harnesses in terms of wear resistance, high-temperature resistance, buffer protection, insulation, and adhesion.

[0014] As a further description of the above technical solution: The lining mechanism includes a collar tube, the outer side of which is disposed on the inner wall of the adhesive layer. Mounting grooves are provided on both sides of the collar tube. The outer side of the mounting shaft passes through the inside of the collar tube and is rotatably connected. The diameter of the mounting shaft is smaller than the diameter of the mounting groove.

[0015] The above solution involves the outer ring tube of the inner lining mechanism being set on the inner wall of the adhesive layer, providing internal support for the tape body and enhancing the overall structural stability of the tape. The mounting grooves on both sides of the ring tube facilitate the insertion and rotation of the mounting shaft inside the ring tube, enabling the cutting mechanism to rotate flexibly and meet the cutting requirements at different angles. Furthermore, the diameter of the mounting shaft is smaller than the diameter of the mounting groove, ensuring that the mounting shaft will not jam due to excessively small gaps or wobble due to excessively large gaps when rotating within the mounting groove. This guarantees the smoothness and accuracy of the cutting mechanism's rotation and also facilitates the installation and removal of the mounting shaft, making future maintenance and replacement easier.

[0016] As a further description of the above technical solution: The top of the cutting frame has a wide hole for the tape to pass through, the bottom of the inner wall of the cutting frame is designed to be arc-shaped for the tape to pass through smoothly, and the bottom of the inner wall of the cutting frame has a knife groove.

[0017] The above solution provides a wide passage for the tape through the wide hole at the top of the cutting frame, allowing the tape to enter the cutting area smoothly and reducing jamming. The bottom of the inner wall is designed to be curved, which keeps the tape stable when passing through and avoids scratching or damage to the tape caused by right angles or sharp edges, thus ensuring the integrity of the tape surface. The knife groove at the bottom of the inner wall provides a precise position for installing the cutting knife, ensuring that the knife is installed firmly and can cut the tape accurately and efficiently during cutting.

[0018] As a further description of the above technical solution: A cutting blade is slidably connected inside the cutting frame, and the shape of the cutting blade head is consistent with the groove of the blade slot.

[0019] The above solution ensures that the shape of the cutting blade head is consistent with the groove of the blade slot, allowing the cutting blade to be precisely embedded in the groove. This guarantees that the cutting blade is in a stable position during operation, preventing shaking or deviation, thereby achieving precise and efficient cutting, reducing cutting errors, ensuring that each cut is clean and neat, and improving cutting quality and effect.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, a cutting mechanism is provided on the product. The cutting mechanism is equipped with a reset component to drive the cutting blade to reset. It is also equipped with manual pressing of the blade head. The blade head is designed with a pointed tip in the middle section, which makes it easier for the blade head to cut the tape, so that the tape will not stick due to incomplete cutting.

[0021] 2. In this utility model, the fleece adhesive tape structure consists of an adhesive tape body, a wear-resistant and high-temperature resistant fleece layer, and an insulating layer. It offers excellent overall protection; the wear-resistant layer resists friction, the high-temperature resistant layer prevents high-temperature deformation, and the insulating layer ensures electrical safety. It has wide applicability; the fleece layer is soft and conforms to irregular surfaces without scratching items, and combined with the various functional layers, it is suitable for the automotive industry.

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0024] Example: A thick fleece wiring harness tape for automobiles, see reference. Figure 1 , Figure 2 and Figure 4 The tape body 1 includes an inner lining mechanism 2 on its inner wall, a cutting mechanism 3 on one side of the inner lining mechanism 2, and a mounting shaft 31 rotatably connected to the inside of the inner lining mechanism 2.

Specifically, the thick fleece wiring harness tape for automobiles uses an inner lining mechanism 2 located on the inner wall of the tape body 1 to provide stable support for the tape, enhancing the overall structural strength and facilitating installation and use. In the cutting mechanism 3 on one side of the inner lining mechanism 2, a mounting shaft 31 is externally rotatably connected to the inside of the inner lining mechanism 2, allowing the cutting frame 33 to rotate flexibly to meet multi-angle cutting requirements. A nut 32 threaded to one side of the mounting shaft 31 facilitates quick disassembly and assembly / fixing of the mounting shaft 31, improving maintenance convenience. The reset components 34 on both sides of the cutting frame 33 are used for fixing... Plate 3401 is fixed to the outside of the cutting frame 33 to ensure a stable connection. The fixing rod 3402 fixed to the top of the fixing plate 3401 and the sliding outer cylinder 3403 slidably connected to the outside form a sliding guide structure. The connecting rod 3404 at the top of the sliding outer cylinder 3403 can be linked to the external structure. One end of the spring 3405 inside the sliding outer cylinder 3403 is fixed to the top of the inner wall of the sliding outer cylinder 3403, and the other end is fixed to the top of the fixing rod 3402. After being compressed, it generates an elastic restoring force, so that the cutting frame 33 can quickly and automatically return to its original position after cutting.

[0025] Reference Figure 1 , Figure 5 The tape body 1 includes an abrasion-resistant layer 11, a high-temperature resistant layer 12 is provided on the inner wall of the abrasion-resistant layer 11, a fleece layer 13 is provided on the inner wall of the high-temperature resistant layer 12, an insulation layer 14 is provided on the inner wall of the fleece layer 13, and an adhesive layer 15 is provided on the inner wall of the insulation layer 14. Specifically, the tape body 1 adopts a multi-layer composite structure. The outermost wear-resistant layer 11 can effectively resist physical damage caused by wire harness friction and scratches during automotive use, extending the tape's service life. The high-temperature resistant layer 12 on the inner wall of the wear-resistant layer 11 can withstand high-temperature environments such as automotive engines, preventing the tape from deforming or melting due to high temperatures, ensuring stable tape performance. The fleece layer 13 on the inner wall of the high-temperature resistant layer 12 is soft and has good cushioning properties, protecting the wire harness from impacts. Its flexibility also allows the tape to fit the wire harness more closely when wrapped. The insulation layer 14 on the inner wall of the fleece layer 13 can effectively isolate current, preventing wire harness leakage and safety hazards, and ensuring the safe operation of the automotive electrical system. The innermost adhesive layer 15 has strong adhesion, firmly adhering to the wire harness surface, making the tape and wire harness tightly bonded and not easy to fall off. It provides comprehensive and reliable protection for automotive wire harnesses from multiple aspects such as wear resistance, high temperature resistance, cushioning protection, insulation safety, and firm adhesion.

[0026] Reference Figure 1 , Figure 3The inner lining mechanism 2 includes a collar tube 21. The outer side of the collar tube 21 is set on the inner wall of the adhesive layer 15. The collar tube 21 has mounting grooves 22 on both sides. The outer side of the mounting shaft 31 passes through the inside of the collar tube 21 and is rotatably connected. The diameter of the mounting shaft 31 is smaller than the diameter of the mounting groove 22. The top of the cutting frame 33 has a wide hole 35 for the tape to pass through. The bottom of the inner wall of the cutting frame 33 is designed to be arc-shaped for the tape to pass through smoothly. The bottom of the inner wall of the cutting frame 33 has a knife groove 36. The cutting blade 37 is slidably connected inside the cutting frame 33. The shape of the blade head of the cutting blade 37 is consistent with the groove of the knife groove 36. Specifically, the collar tube 21 of the inner lining mechanism 2 is externally set on the inner wall of the adhesive layer 15, providing internal support for the tape body 1 and enhancing the overall structural stability. The mounting grooves 22 on both sides of the collar tube 21 facilitate the passage and rotation of the mounting shaft 31, allowing the cutting mechanism 3 to rotate flexibly to meet the cutting needs of different angles. The diameter of the mounting shaft 31 is smaller than the diameter of the mounting groove 22, ensuring smooth rotation without shaking. The tape at the top of the cutting frame 33 has a wide hole 35 to provide a spacious channel for the tape, reducing jamming during passage. The arc design at the bottom of the inner wall allows the tape to pass through smoothly, avoiding damage. The knife groove 36 at the bottom of the inner wall provides a precise installation position for the cutting knife 37. The cutting knife 37, which is slidably connected inside the cutting frame 33, has a blade head shape that matches the groove of the knife groove 36, ensuring that the cutting knife 37 is stably embedded in the knife groove 36 during operation, achieving precise and efficient cutting and effectively reducing errors.

[0027] The implementation principle of this application embodiment is as follows: When using the automotive thick fleece wiring harness tape, the adhesive layer 15 of the tape body 1 adheres to the automotive wiring harness, and the multi-layer structure (wear-resistant layer 11, high-temperature resistant layer 12, fleece layer 13, insulation layer 14, adhesive layer 15) plays a protective role. The collar tube 21 of the inner lining mechanism 2 provides internal support. The mounting shaft 31 passes through the mounting grooves 22 on both sides of the collar tube 21 and is fixed by the nut 32. Rotating the mounting shaft 31 can adjust the angle of the cutting mechanism 3. The tape passes through the tape through the wide hole 35 at the top of the cutting frame 33 and is smoothly conveyed along the arc-shaped structure at the bottom of the inner wall. When cutting is required, the cutting blade 37 inside the cutting frame 33 is pushed so that its blade head is embedded in the blade groove 36 to cut the tape. After cutting is completed, the spring 3405 of the reset assembly 34 releases elastic potential energy, pushes the sliding outer cylinder 3403 to slide along the fixed rod 3402, and drives the cutting frame 33 to reset.
