Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to automotive wiring harnesses, and more particularly to adaptive wiring harness sleeves. Background Technology

[0002] As a key component of automotive electrical systems, wiring harnesses play a crucial role in connecting various electrical components and ensuring the reliable transmission of electrical signals and energy. The rationality and safety of their arrangement directly affect the stability, reliability, and safety performance of the entire vehicle's electrical system.

[0003] In modern automobiles, especially in the engine compartment of traditional fuel vehicles and hybrid vehicles, the internal space is compact and the environment is complex. Wiring harnesses often need to pass through narrow areas and be routed along complex three-dimensional paths. Specifically, their paths often have sharp turns in multiple directions, need to bypass sharp edges of sheet metal to avoid cuts, cross various structural supports, and stay away from high heat sources such as the engine to avoid the effects of high temperatures. Such complex working conditions place extremely high demands on the physical protection of wiring harnesses.

[0004] Currently, conventional protection methods mainly involve using tubular materials such as corrugated pipes, polyurethane sleeves, or braided mesh tubes to wrap the wire harness. To prevent the wire harness from shifting due to vehicle vibration, it is often necessary to tightly bind the wire harness inside the sleeve. This tight binding structure severely restricts the heat exchange between the wire harness and the surrounding air, causing the heat generated by the resistance heat of the wires and the heat radiation from the environment during operation to be unable to dissipate in time. This results in the accumulation of "volume heat" inside the wire harness. This heat accumulation not only accelerates the aging of the insulation layer and increases resistance, leading to voltage drop and affecting the performance of electrical equipment, but may also cause local overheating in extreme cases, posing a potential electrical fire hazard.

[0005] Therefore, how to avoid heat buildup in the wiring harness inside the casing is a technical problem that urgently needs to be solved in this field.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0007] This disclosure provides at least one adaptive wire harness sleeve to solve the technical problem of easy sleeve displacement under complex three-dimensional wiring paths.

[0008] In a first aspect, embodiments of this disclosure provide an adaptive wire harness sleeve, comprising: a plurality of rigid sleeves having at least one through hole on their outer peripheral wall; and a plurality of flexible sleeves, wherein the rigid sleeves and flexible sleeves are alternately spaced along their axial direction, and the inner wall of each flexible sleeve has at least one protrusion corresponding to the position of the through hole, and the flexible sleeve is detachably fitted onto the outer periphery of the rigid sleeve through the protrusion; wherein the rigid sleeve is used to tighten the wire harness, and the flexible sleeve wraps around the port of the rigid sleeve, so that a movable gap is formed between the inner wall of the flexible sleeve and the wire harness; after the rigid sleeve and the flexible sleeve are combined, the wire harness is tightened in a segmented manner.

[0009] In one alternative embodiment, the rigid sleeve is an open 1.5-turn spring-like structure.

[0010] In one optional embodiment, a stop strip is provided on the free end of the outer ring of the spring-shaped rigid sleeve. After the rigid sleeve tightens the wire harness, the stop strip is inserted into the through hole to fix the ring opening.

[0011] In one alternative embodiment, the rigid sleeve is a ring-shaped structure with a fixed opening.

[0012] In one optional embodiment, the surface of the flexible sleeve is provided with multiple through holes or has a mesh structure. In one alternative embodiment, the flexible sleeve is made of rubber, silicone, polyurethane, thermoplastic elastomer (TPE), or polyvinyl chloride (PVC).

[0013] Secondly, this disclosure also provides an adaptive wire harness sleeve, comprising: a plurality of rigid sleeves, which are open 1.5-turn spring-like structures, the outer peripheral wall of the rigid sleeves having at least one through hole; a plurality of flexible sleeves, the rigid sleeves and flexible sleeves being alternately spaced along their axial direction, the inner wall of the flexible sleeves having at least one protrusion corresponding to the position of the through hole, the flexible sleeves being detachably fitted onto the outer periphery of the rigid sleeves through the protrusions; wherein, the rigid sleeves are used to tighten the wire harness, the flexible sleeves are wrapped around the ports of the rigid sleeves, so that a movable gap is formed between the inner wall of the flexible sleeves and the wire harness; after the rigid sleeves and flexible sleeves are combined, the wire harness is tightened in a segmented manner.

[0014] In one optional embodiment, a stop strip is provided on the free end of the outer ring of the spring-shaped rigid sleeve. After the rigid sleeve tightens the wire harness, the stop strip is inserted into the through hole to fix the ring opening.

[0017] The beneficial effects of this utility model are that it provides an adaptive wire harness sleeve, which uses rigid sleeves and flexible sleeves alternately spaced along the axial direction and has a detachable combination structure. This allows for flexible adjustment of the number, installation position, and spacing of the rigid and flexible sleeves according to actual wiring needs, forming an alternating "fixed-relaxed-fixed" constraint mode on the wire harness path.

[0028] Research has revealed that in the engine compartment of modern automobiles, especially traditional gasoline and hybrid vehicles, the internal space is compact and the environment is complex. Wiring harnesses often need to pass through narrow areas and be routed along complex three-dimensional paths. Specifically, their paths often involve sharp turns in multiple directions, need to avoid sharp edges of sheet metal to prevent cuts, cross various structural supports, and stay away from high heat sources such as the engine to avoid the effects of high temperatures. Such complex operating conditions place extremely high demands on the physical protection of wiring harnesses.

[0029] Currently, conventional protection methods mainly involve using tubular materials such as corrugated pipes, polyurethane sleeves, or braided mesh tubes to wrap the wire harness. To prevent the wire harness from shifting due to vehicle vibration, it is often necessary to tightly bind the wire harness inside the sleeve. This tight binding structure severely restricts the heat exchange between the wire harness and the surrounding air, causing the heat generated by the resistance heat of the wires and the heat radiation from the environment during operation to be unable to dissipate in time. This results in the accumulation of "volume heat" inside the wire harness. This heat accumulation not only accelerates the aging of the insulation layer and increases resistance, leading to voltage drop and affecting the performance of electrical equipment, but may also cause local overheating in extreme cases, posing a potential electrical fire hazard.

[0030] Therefore, how to avoid heat buildup in the wiring harness inside the casing is a technical problem that urgently needs to be solved in this field.

[0031] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] like Figures 1 to 3 As shown, some embodiments provide an adaptive wire harness sleeve, including: a plurality of rigid sleeves 1, the outer peripheral wall of which is provided with at least one through hole 11; the rigid sleeve 1 is the main support and fixing component of the sleeve, and its "rigidity" ensures that the wire harness 3 can be firmly clamped and positioned at key points (such as crossing the bracket or going around the sharp edge) to prevent displacement and wear caused by vehicle vibration.

[0035] The through holes 11 on the outer peripheral wall of the rigid sleeve 1 firstly serve as heat dissipation holes, allowing the heat generated by the bound wire harness to directly convect and exchange with the outside air through these holes, greatly improving the problem of heat accumulation; secondly, the holes serve as connection interfaces, providing a position for the protrusion 21 of the flexible sleeve 2 to be inserted and locked, realizing a modular and detachable connection between the rigid and flexible components.

[0036] This design makes the entire pipe system easy to assemble and maintain, and allows for individual replacement of damaged sections, reducing costs.

[0037] As a preferred embodiment, the rigid sleeve 1 can be made of a material with high mechanical strength and stiffness and good heat resistance, such as nylon (PA6, PA66), polypropylene (PP) or engineering plastics such as PBT, to ensure that it maintains its shape and function under long-term vibration and high temperature.

[0038] A plurality of flexible sleeves 2, rigid sleeves 1 and flexible sleeves 2 are alternately spaced along their axial direction. The inner wall of the flexible sleeve 2 is provided with at least one protrusion 21 corresponding to the position of the through hole 11. The flexible sleeve 2 is detachably sleeved on the outer periphery of the rigid sleeve 1 through the protrusion 21. Among them, the rigid sleeve 1 is used to tighten the wire harness, and the flexible sleeve 2 is wrapped around the end of the rigid sleeve 1, so that the inner wall of the flexible sleeve 2 and the wire harness form an movable gap; after the rigid sleeve 1 and the flexible sleeve 2 are combined, the wire harness is tightened in a segmented manner.

[0039] Rigid sleeve 1 and flexible sleeve 2 are alternately spaced along their axial direction. The inner wall of flexible sleeve 2 is provided with at least one protrusion 21 corresponding to the position of through hole 11. Flexible sleeve 2 is detachably sleeved on the outer periphery of rigid sleeve 1 through protrusion 21.

[0040] Specifically, the flexible sleeve 2 is the key to achieving "segmented tightening" and "forming a movable gap". It is alternately set with the rigid sleeve 1, breaking the state of tight binding throughout the traditional sleeve.

[0041] The flexible sleeve precisely engages with the through hole 11 of the rigid sleeve via the protrusion 21 on its inner wall (which can be designed as spherical, wedge-shaped, etc.), achieving quick insertion and fixation. This detachable connection method gives the sleeve great assembly flexibility.

[0042] The main function of the flexible sleeve 2 is to wrap and protect the port of the rigid sleeve 1, preventing the wire harness from being cut or excessively worn at the edge of the rigid sleeve 1. At the same time, its flexibility allows it to bend within a certain range to adapt to complex wiring paths.

[0043] As a preferred embodiment, the flexible sleeve 2 is made of a material with excellent flexibility, temperature resistance, high elasticity, wear resistance and weather resistance (resistance to ozone and ultraviolet aging), including rubber (such as EPDM), silicone (VMQ), polyurethane (PU), thermoplastic elastomer (TPE) or polyvinyl chloride (PVC).

[0044] "Segmented clamping" means that the wire harness 3 is only firmly clamped at the position of the rigid sleeve 1 to ensure fixation, while in the long area covered by the flexible sleeve 2, the wire harness 3 is in the "moving gap" and does not make close contact with the inner wall of the sleeve; this gap forms a natural air flow channel; when the vehicle is moving, the air in the engine compartment can circulate in this gap, effectively carrying away the heat generated when the wire harness is working, fundamentally solving the "volume heat" problem; at the same time, the "point" fixation provided by the rigid sleeve 1 is sufficient to meet the requirements for fixing the wire harness 3.

[0045] The rigid sleeve 1 is an open, 1.5-turn spring-like structure. A stop strip 12 is provided on the free end of the outer ring of the spring-like rigid sleeve 1. After the rigid sleeve 1 tightens the wire harness, the stop strip 12 is inserted into the through hole 11 to fix the ring opening. The spring-like structure makes the rigid sleeve itself elastic, which can be opened like a spring clip and put on the wire harness 3. The operation is extremely simple, without the need to put it through the end of the wire harness 3, making it particularly suitable for after-sales maintenance and partial modification.

[0046] The engagement of the stop bar 12 and the through hole 11 forms a self-locking mechanism: after the stop bar is inserted into the hole, it prevents the rigid sleeve 1 from accidentally springing open during vibration, ensuring the reliability of the fixation; in addition, this design reuses the function of the heat dissipation hole (through hole 11) as a mechanical locking hole. The rigid sleeve 1 is a ring-shaped structure with a fixed opening; the rigid sleeve 1 with a fixed opening is suitable for assembly scenarios where it is directly inserted into the production line bundle 3; the ring-shaped structure with a fixed opening can provide stronger and more uniform clamping force and circumferential support, resulting in higher mechanical strength and better protection. It is also connected to the flexible sleeve through the through hole 11 to achieve heat dissipation.

[0047] The surface of the flexible sleeve 2 is provided with multiple through holes or a mesh structure. Opening through holes or directly using a mesh braided structure on the surface of the flexible sleeve 2 can greatly increase the overall air permeability and heat dissipation surface area of ​​the sleeve. This not only facilitates the exhaust of internal hot air, but also allows external cooling air to come into more direct contact with the wire harness 3. It can even use the airflow to generate a "suction" effect during driving to actively enhance heat dissipation. The mesh structure achieves maximum heat dissipation optimization while ensuring sufficient flexibility and protection.

[0048] The flexible sleeve 2 is made of rubber, silicone, polyurethane, thermoplastic elastomer (TPE), or polyvinyl chloride (PVC).

[0049] Experiment 1: Temperature Rise Comparison Experiment Method: Select a section of wire harness 3 of the same length and with the same load (current) in the engine compartment of the same vehicle model; one group uses a traditional fully enclosed corrugated tube (Φ20mm), and the other group uses the rigid-flexible alternating sleeve provided by this invention (the rigid sleeve has an inner diameter of Φ18mm to tighten, and the flexible sleeve has an inner diameter of Φ22mm to form a gap); in a constant temperature chamber at an ambient temperature of 85°C, apply a rated current of 25A to wire harness 3 and continue to work for 2 hours, and use a thermocouple to measure the temperature at the midpoint of wire harness 3.

[0050] Experimental results: Traditional corrugated conduit harness group 3: final stable temperature 127.5°C; harness 3 shows significant heat accumulation, far exceeding the long-term heat resistance temperature of PVC insulation material (usually 105°C).

[0051] In this embodiment, there are 3 sets of tubular wire harnesses: the final stable temperature is 98.3°C; the temperature is effectively controlled, which is about 29.2°C lower than the traditional solution, and is within the safe range.

[0052] Test 2: Vibration durability and heat dissipation sustainability test Method: Two sets of samples were fixed on a vibration test bench to simulate engine compartment vibration conditions (frequency 20-2000Hz, acceleration 10g) and vibrated continuously for 500 hours; the temperature rise test of test one was repeated every 100 hours during this period.

[0053] Experimental results: Traditional corrugated pipe assembly: The temperature rise curve increases slowly with the increase of vibration time. Due to the vibration, the wire harness 3 is squeezed more tightly with the tube sleeve, which worsens heat dissipation. After 500 hours, the temperature rises to 132.1°C.

[0054] In this embodiment, the sleeve assembly maintains a stable temperature rise curve, and the segmented fixing effectively prevents the overall creep and compression of the wire harness 3, thus maintaining the movement gap. After 500 hours, the temperature remains stable at around 99.0°C, demonstrating excellent durability and stability.

[0055] Test 3: Comparative Test of Protective Performance (Dustproof and Waterproof) Methods: In accordance with the IP protection rating standards, the two groups of samples were tested for IP5X (dustproof) and IPX4 (splashproof).

[0056] Experimental results: Traditional bellows assembly: easily passes IP5X and IPX4 tests.

[0057] In this embodiment, the sleeve assembly (mesh flexible sleeve) only passed the IP5X (dustproof) test due to its mesh design, but not the IPX4 (splashproof) test. This indicates that the full mesh design is suitable for dry areas where waterproofing requirements are not high. If waterproofing is required, a flexible material with a non-porous surface but breathable material (such as microporous polyurethane) can be selected, or an additional layer of waterproof tape can be wrapped around the water-contaminated areas of the structure. This demonstrates the significant advantage of this solution, which allows for flexible selection based on the environmental needs of different areas.

[0058] Some embodiments provide an adaptive wire harness sleeve, comprising: a plurality of rigid sleeves 1, which are open 1.5-turn spring-like structures, with at least one through hole 11 on the outer peripheral wall of the rigid sleeve 1; a plurality of flexible sleeves 2, the rigid sleeves 1 and the flexible sleeves 2 being alternately spaced along their axial direction, the inner wall of the flexible sleeve 2 having at least one protrusion 21 corresponding to the position of the through hole 11, and the flexible sleeve 2 being detachably fitted onto the outer periphery of the rigid sleeve 1 through the protrusion 21; wherein, the rigid sleeve 1 is used to tighten the wire harness, and the flexible sleeve 2 wraps around the port of the rigid sleeve 1, so that an movable gap is formed between the inner wall of the flexible sleeve 2 and the wire harness; after the rigid sleeve 1 and the flexible sleeve 2 are combined, the wire harness is tightened in a segmented manner.

[0059] A stop strip 12 is provided on the free end of the outer ring of the spring-shaped rigid sleeve 1. After the rigid sleeve 1 tightens the wire harness, the stop strip 12 is inserted into the through hole 11 to fix the ring opening. The surface of the flexible sleeve 2 is provided with multiple through holes or a mesh structure. The material of the flexible sleeve 2 is rubber, silicone, polyurethane, thermoplastic elastomer TPE or polyvinyl chloride PVC.
