[0032] See Figures 1 to 5 As shown in the figure, in a first aspect, an embodiment of the present invention provides a wrapping mechanism for a wire harness, including: a wrapping member 1, the wrapping member 1 is provided with a plurality of incisions 2, the plurality of incisions 2 are linearly distributed and there is a gap between two adjacent incisions 2; when the wrapping member 1 wraps around the outer periphery of the wire harness body 3, the distribution direction of the incisions 2 is parallel to the axis direction of the wire harness body 3.

[0033] Specifically, the wrapping mechanism of this embodiment breaks the continuity of the wrapping member 1 by providing a plurality of incisions 2 which are linearly distributed and have gaps between adjacent ones on the wrapping member 1, and making the distribution direction of the incisions 2 parallel to the axis direction of the wire harness body 3. When the wrapping member 1 bends around the wire harness body 3, small deformations can occur at the incisions 2, so as to disperse the stress generated during the wrapping process to each incision 2 area, and avoid stress concentration at a certain place to cause damage to the wrapping member 1.

[0034] During actual operation, the operator wraps the wrapping member 1 around the wire harness body 3. Since the distribution direction of the incisions 2 is consistent with the axis direction of the wire harness body 3, as the wrapping member 1 gradually fits the wire harness, the incisions 2 will open or close at a certain angle as the wrapping member 1 bends. These small deformations continuously adjust the stress distribution inside the wrapping member 1, so that the wrapping member 1 can wrap more smoothly around the outer periphery of the wire harness.

[0035] This structural design effectively reduces the stress generated during the wrapping process, significantly reducing the probability of damage to the package 1 due to stress concentration and remarkably improving the service life of the package 1. At the same time, the package 1 can better conform to the wire harness, enhancing the protection effect on the wire harness and ensuring stable protection of the wire harness during use.

[0036] In a specific embodiment, when the package 1 is in the unfolded state, the two side regions of the package 1 are respectively the first overlapping region 1a and the second overlapping region 1b, and the middle region is the base fitting region 1c, and the incision 2 is provided in the base fitting region 1c; when the package 1 is wrapped around the outer periphery of the wire harness body 3, the first overlapping region 1a fits onto the second overlapping region 1b, and the base fitting region 1c fits onto the outer periphery of the wire harness body 3.

[0037] Specifically, when the package 1 is in the unfolded state, it is divided into the first overlapping region 1a, the second overlapping region 1b, and the base fitting region 1c, clarifying the functions of each region. The base fitting region 1c is used to directly fit onto the wire harness body 3 to tightly wrap the wire harness body 3; the first overlapping region 1a and the second overlapping region 1b on both sides cooperate with each other during wrapping to achieve fixation and sealing. The incision 2 is provided in the base fitting region 1c because the base fitting region 1c is in direct contact with the wire harness, and the stress generated during wrapping is concentrated in this region. By providing the incision 2 in the base fitting region 1c, the stress can be dispersed, avoiding the failure of the fit between the base fitting region 1c and the wire harness due to excessive stress.

[0038] In addition, the present application also provides two wrapping structures, namely the folded wrapping and the winding wrapping, to meet different usage requirements.

[0039] Folded wrapping structure: The base fitting region 1c is folded around the wire harness and wraps the outer periphery of the wire harness body 3, the inner side of the first overlapping region 1a fits onto the inner side of the second overlapping region 1b, and neither the first overlapping region 1a nor the second overlapping region 1b contacts the wire harness body 3. Through this structural design, wrapping fixation is achieved without increasing the number of wrapping layers on the outer periphery of the wire harness. When using this structure to wrap the wire harness body 3, the operator first aligns the base fitting region 1c with the wire harness body 3 to make it tightly fit on the surface of the wire harness. Then, the base fitting region 1c is folded along the middle, and the inner side of the first overlapping region 1a is made to fit onto the inner side of the second overlapping region 1b, finally achieving that the outer periphery of the wire harness body 3 is only wrapped by the base fitting region 1c, and the first overlapping region 1a and the second overlapping region 1b only play a fixing role and do not contact the wire harness body 3.

[0040] Winding wrapping structure: The inner sides of the second overlapping area 1b and the base fitting area 1c are jointly attached to the outer periphery of the wire harness body 3, and the inner side of the first overlapping area 1a is attached to the outer side of the second overlapping area 1b. The incision 2 can be linearly distributed longitudinally at any position in the base fitting area 1c to adapt to the stress conditions at different positions during the winding process. When wrapping the wire harness body 3 with this structure, the second overlapping area 1b and the base fitting area 1c are successively wound and attached to the outer periphery of the wire harness body 3 to jointly wrap the wire harness, and finally the first overlapping area 1a is attached to the outer side of the second overlapping area 1b to complete the wrapping.

[0041] Through these two wrapping structure designs, the wrapping mechanism can be applied to different demand scenarios. The folding wrapping structure reduces the number of wrapping layers and lowers the material cost; the winding wrapping structure increases the number of wrapping layers, improves the sealing performance and firmness, and the flexible distribution of the incision 2 adapts to the complex wire harness shape and enhances the wrapping stability. At the same time, the incision 2 is provided in the base fitting area 1c, which effectively disperses the wrapping stress and improves the wrapping reliability and the wire harness protection effect.

[0042] In a specific embodiment, the incision 2 is provided at the middle position of the base fitting area 1c.

[0043] Specifically, setting the incision 2 at the middle position of the base fitting area 1c can flexibly adapt to the two wrapping structures of folding wrapping and winding wrapping. In the folding wrapping structure, the position of the incision 2 is at the diagonal of the connection between the first overlapping area 1a and the second overlapping area 1b, that is, the folding position. Such a setting can form a symmetric stress-bearing structure with the incision 2 as the center line when the wrapping piece 1 is folded. When the wrapping piece 1 undergoes bending deformation, the incision 2 is like the balance point of stress dispersion, prompting the two sides of the wrapping piece 1 to deform evenly, efficiently dispersing the stress to the entire wrapping piece 1, and avoiding wrinkles and breakage caused by unilateral stress concentration; in the winding wrapping structure, the incision 2 located in the middle of the base fitting area 1c can serve as the "hub" of stress dispersion, cooperating with the base fitting area 1c and the overlapping area structure to evenly spread the stress to each part of the base fitting area 1c and prevent local stress from being too high. Compared with the structure where the incision 2 is at the edge of the base fitting area 1c, the incision 2 located in the middle position can ensure the flatness of the wrapping piece 1 during folding and better handle complex stresses during winding.

[0044] In the folded wrapping structure, taking the packaging of the harness body 3 inside the car dashboard as an example, the operator aligns the base fitting area 1c with the harness body 3, and then folds it in half. Since the cutout 2 is located at the diagonal position where the first overlapping area 1a and the second overlapping area 1b are connected, that is, the folding position, the two sides of the wrapping piece 1 are highly synchronized when deformed by force. Even if the harness body 3 has a certain curvature, the wrapping piece 1 can fit tightly, and the surface is flat and wrinkle-free. When winding and wrapping the complex harness of the industrial robot, first fit the base fitting area 1c to the harness body 3. As the wrapping piece 1 is gradually wound, the cutout 2 in the middle position guides the wrapping piece 1 to deform evenly, effectively dispersing the complex stress caused by the bending and turning of the harness body 3, ensuring that the wrapping piece 1 is firmly fitted to the harness body 3, and is not prone to loosening or breakage even after long-term use.

[0045] The position design of the cutout 2 enables the wrapping mechanism to show excellent performance under both wrapping structures. When folded in half, the flatness and aesthetics of the wrapping are significantly improved, meeting the appearance requirements of high-demand scenes such as electronic equipment; when wound and wrapped, the wrapping piece 1 is more adaptable to the complex shape of the wiring harness body 3, and the wrapping stability and reliability are improved, which is suitable for protecting the wiring harness body 3 in complex environments such as industrial machinery. At the same time, the uniform stress distribution greatly reduces the material fatigue of the wrapping piece 1, effectively reducing the cost of later maintenance and replacement, and providing a high-quality solution for the packaging of the wiring harness body 3 that combines efficiency, stability and economy.

[0046] It is understandable that, in other embodiments, the cutout 2 may also be disposed at any other position of the substrate bonding area 1 c to accommodate different stress distribution conditions.

[0047] In a specific embodiment, the cutout 2 is arranged in a strip shape, and the length direction is parallel to the axial direction of the wire harness body 3 .

[0048] Specifically, the strip cutout 2 provides a clear guide path, so that when the wrapping layer is bent, the stress is evenly dispersed along the edge of the entire length of the cutout 2, avoiding extreme stress concentration. The length direction of the cutout 2 is parallel to the axial direction of the harness body 3, ensuring that the bending is performed along the bend or fork of the harness body 3 and other locations where deformation is required, making full use of the length of the cutout 2 to disperse the stress, forming an efficient stress release structure, and effectively coping with stress problems during folding and winding.

[0049] In the folded wrapping structure, the strip-shaped incision 2 located at the middle position of the base fitting area 1c serves as a folding line. When the wrapping 1 is folded, it guides the wrapping 1 to bend and forms a symmetric stress-bearing structure centered on itself, prompting the two sides of the wrapping 1 to deform uniformly, dispersing the stress efficiently throughout the wrapping 1, and avoiding wrinkles and breakages caused by unilateral stress concentration. In the winding wrapping structure, the strip-shaped incision 2 can undergo tensile or compressive deformation circumferentially according to the stress conditions at different positions of the wire harness body 3, flexibly adapting to the complex stress distribution during the winding process and ensuring that the wrapping 1 closely adheres to the wire harness body 3.

[0050] By designing the incision 2 as strip-shaped, the stress dispersion ability of the wrapping 1 in the two wrapping structures is significantly improved, effectively coping with the wrapping situation with large stress. Through the circumferential deformation, the local stress concentration problem caused by the bending of the wrapping 1 is alleviated, reducing the risk of material fatigue and damage. At the same time, its regular shape is convenient for processing and manufacturing, reducing the production difficulty and cost, improving the production efficiency, and enhancing the practicability and economy of the present invention while ensuring the wrapping effect.

[0051] More specifically, the length range of the incision 2 is 4 - 5 mm, the width range is 0.8 - 2.2 mm, and the interval length between the incisions 2 is 5 - 8 mm. The length of the incision 2 is set to 4 - 5 mm. This range can effectively guide the release of pressure in the stress concentration area when the protective layer 11 bends, avoiding insufficient stress dispersion due to too short a length, and can also prevent the overall structural strength of the protective layer 11 from being weakened due to too long a length, maintaining the material's load-bearing capacity. The width is controlled within 0.8 - 2.2 mm, which not only meets the extension space requirements during material deformation, avoiding the incision 2 from closing or having limited deformation due to being too narrow, but also can maintain the wrapping tightness through an appropriate width, preventing the protective layer 11 from becoming loose or the wire harness body 3 from shaking due to being too wide. The interval length between the incisions 2 is 5 - 8 mm, which can balance the stress dispersion effect, avoiding a sudden drop in local strength or the risk of material tearing due to too short an interval. At the same time, through a reasonable spacing, an effective stress conduction path is ensured between adjacent incisions 2, enhancing the overall stability of the protective layer 11 in scenarios such as bending and stretching, enabling the protective layer 11 to achieve an optimal balance between stress release and structural strength while adapting to the specifications of the wire harness body 3.

[0052] It can be understood that in other embodiments, the length range, width range, and interval length of the incision 2 can also be set to other values as needed to adapt to the size changes of the wire harness body 3.

[0053] In a specific embodiment, the wrapping 1 includes a protective layer 11 and an adhesive layer 12 provided on the inner side of the protective layer 11, and the adhesive layer 12 is used to adhere to the outer periphery of the wire harness body 3.

[0054] Specifically, the package 1 is designed with a double-layer structure of a protective layer 11 and an adhesive layer 12. The protective layer 11 is located on the outside and can resist the influence of external physical impacts, friction, and environmental factors on the wire harness body 3, providing a physical protection barrier for the wire harness body 3. The adhesive layer 12 is located inside the protective layer 11 and realizes a firm connection between the package 1 and the wire harness body 3 through its own viscosity, ensuring that the package 1 is stably wrapped around the wire harness body 3. Whether it is folded wrapping or winding wrapping, this double-layer structure can play its corresponding role to ensure the wrapping effect.

[0055] During use, align the adhesive layer 12 of the package 1 with the wire harness body 3, gently press the package 1 to make the adhesive layer 12 fully contact the surface of the wire harness body 3, and use the viscosity of the adhesive layer 12 to closely fit the package 1 around the outer circumference of the wire harness body 3. After wrapping is completed, the protective layer 11 continues to play its role, blocking various damage factors from the outside and protecting the wire harness body 3. During the processes of folded wrapping and winding wrapping, the adhesive layer 12 can ensure the connection between the package 1 and the wire harness body 3, and the protective layer 11 always provides protection.

[0056] This double-layer structure design not only ensures the firmness of the connection between the package 1 and the wire harness body 3, making the package 1 not easily fall off, but also effectively improves the protection ability for the wire harness body 3 through the setting of the protective layer 11, extends the service life of the wire harness body 3, meets the protection requirements of the wire harness body 3 in different usage scenarios, and is applicable to the two wrapping structures.

[0057] In a specific embodiment, the incision 2 is provided on the protective layer 11.

[0058] By setting the incision 2 on the protective layer 11 and utilizing the deformability of the protective layer 11, the protective layer 11 can better bend and deform along with the shape of the wire harness body 3 during the wrapping process. The deformation of the protective layer 11 drives the entire package 1 to adapt to the contour of the wire harness body 3. At the same time, since the incision 2 does not involve the adhesive layer 12, it can ensure that the viscosity of the adhesive layer 12 is not affected and guarantee the connection stability between the package 1 and the wire harness body 3. Under the two wrapping structures, this design can achieve the balance of stress dispersion and stable connection.

[0059] When wrapping the wire harness body 3, the incision 2 on the protective layer 11 deforms as the package 1 bends, and the material of the protective layer 11 generates a small displacement at the incision 2, enabling the protective layer 11 to closely fit the irregular surface of the wire harness body 3. And the adhesive layer 12 always maintains good viscosity, firmly fixing the package 1 on the wire harness body 3 to achieve stable wrapping. Whether it is folded wrapping or winding wrapping, the deformation of the protective layer 11 and the viscosity of the adhesive layer 12 can work together.

[0060] This setting scheme of the incision 2 maintains the stability of the connection between the package 1 and the wire harness body 3 while ensuring the stress dispersion effect of the package 1, ensuring that the package 1 will not fail due to connection problems during the process of protecting the wire harness body 3, and improving the overall performance of the wrapping mechanism under the two wrapping structures.

[0061] In a specific embodiment, the depth of the incision 2 is the same as the thickness of the protective layer 11.

[0062] Specifically, making the depth of the incision 2 the same as the thickness of the protective layer 11 maximizes the stress dispersion effect of the incision 2 on the basis of ensuring the structural strength of the protective layer 11. When the protective layer 11 is deformed under force during the wrapping process, the incision 2 with the same depth as the thickness of the protective layer 11 can fully participate in the deformation process, disperse the stress sufficiently, and at the same time avoid weakening the strength of the protective layer 11 due to the excessive depth of the incision 2. During the folding wrapping and winding wrapping processes, this depth design can ensure the performance of the protective layer 11.

[0063] During the wrapping operation, when the protective layer 11 is stressed by the wire harness body 3 being wrapped, the material at the incision 2 moves with the deformation of the protective layer 11. Since the depth of the incision 2 is the same as the thickness of the protective layer 11, the incision 2 can fully absorb and disperse the stress, enabling the protective layer 11 to deform uniformly while maintaining sufficient strength to resist external physical effects. Regardless of which wrapping structure, the balance between stress dispersion and the strength of the protective layer 11 can be achieved.

[0064] This design of the depth of the incision 2 achieves the best stress dispersion effect on the premise of ensuring that the protective layer 11 has sufficient strength to cope with the influence of the external environment, enabling the package 1 to effectively protect the wire harness body 3 while having a stable and reliable self-structure, and extending the service life of the package 1 under the two wrapping structures.

[0065] In a specific embodiment, a release paper layer 4 is detachably connected to the inner side of the adhesive layer 12.

[0066] Specifically, a detachable release paper layer 4 is provided on the inner side of the adhesive layer 12. Using its low adhesiveness to the adhesive layer 12, the adhesive layer 12 is isolated when the package 1 is not in use, preventing the isolation layer from contacting external objects, effectively protecting the adhesiveness of the adhesive layer 12, and ensuring its normal fixing function during use.

[0067] When using the package 1, the operator first carefully tears off the release paper layer 4 from the inner side of the adhesive layer 12 to expose the sticky surface of the adhesive layer 12, and then, according to the folding wrapping or winding wrapping method, adheres the adhesive layer 12 of the package 1 to the wire harness body 3 to complete the wrapping operation through the adhesiveness of the adhesive layer 12.

[0068] The setting of the release paper layer 4 effectively protects the adhesiveness of the adhesive layer 12, avoids the failure of the package 1 caused by the accidental adhesion of the adhesive layer 12, improves the convenience and reliability of the package 1 used in the two package structures, and makes the packaging operation more convenient and efficient.

[0069] In a specific embodiment, the protective layer 11 is made of sponge.

[0070] Specifically, sponge is selected as the material of the protective layer 11. Based on the good elasticity and buffering performance of the sponge, when the wire harness body 3 is subjected to an external impact, the sponge can absorb the impact energy through its own compression and rebound, reducing the impact on the wire harness body 3. At the same time, the flexibility of the sponge enables it to easily adapt to various shapes of the wire harness body 3, facilitating the bending and fitting of the package 1. During the folding and winding packaging processes, the sponge protective layer 11 can play its unique advantages.

[0071] When wrapping the wire harness body 3, the sponge protective layer 11 is attached to the surface of the wire harness body 3. The sponge can closely fill the uneven parts on the surface of the wire harness body 3, forming a good package. When the wire harness body 3 encounters external collisions, squeezes and other situations, the sponge protective layer 11 absorbs the impact energy and protects the internal structure of the wire harness body 3 from damage. Regardless of which packaging structure, the sponge protective layer 11 can provide good buffering and fitting effects.

[0072] The sponge protective layer 11 significantly improves the protection performance of the wire harness body 3, can effectively cope with various external impacts and vibrations, and ensures the normal operation of the wire harness body 3 in a complex environment. At the same time, due to the soft characteristics of the sponge, the packaging process is smoother, reducing the packaging operation difficulty of the two packaging structures.

[0073] It can be understood that in other embodiments, the protective layer 11 can also be made of materials such as rubber, polyurethane, polyvinyl chloride (PVC), silicone rubber, metal braided mesh, etc., and all can adapt to the design of setting the incision 2 on the protective layer 11. Rubber has good elasticity, and the incision 2 can effectively disperse stress, and the deformation at the incision 2 is coordinated during bending; polyurethane has high strength, and the incision 2 can guide deformation to avoid material damage caused by stress concentration; PVC has good processability, and the incision 2 is conducive to its deformation in a predetermined direction during packaging; silicone rubber has strong heat resistance, and the incision 2 enables it to still release stress through deformation at high and low temperatures; metal braided mesh has high hardness, and the reasonably designed incision 2 can make it moderately deform at the turning of the wire harness body 3 during packaging, while maintaining the structural strength and shielding performance. After setting the incision 2 on these materials, they can all cooperate with the overall structure to achieve stress dispersion during the folding and winding packaging processes, adapt to the shape change of the wire harness body 3, and ensure the protection effect of the wire harness body 3.

[0074] In a second aspect, an embodiment of the present invention further provides a wire harness, including a wire harness body 3, and the outer periphery of the wire harness body 3 is covered with the above-mentioned wrapping mechanism for the wire harness.

[0075] Applying the above-mentioned wrapping mechanism with various innovative structures and functions to the wire harness body 3, through the unique design of the wrapping mechanism, comprehensive protection and performance improvement are provided for the wire harness. Multiple innovation points such as the stress dispersion design, zoned wrapping design, and multi-layer structure design of the wrapping mechanism work together, combined with two wrapping structures, to meet the requirements of the wire harness in different usage scenarios.

[0076] When producing the wire harness, according to the specifications, shape, and usage environment of the wire harness body 3, select a suitable wrapping mechanism, and determine to use the folded wrapping or winding wrapping structure to tightly cover the wrapping mechanism around the outer periphery of the wire harness body 3 to complete the production process of the wire harness.

[0077] Through the application of the wrapping mechanism and the selection of two wrapping structures, the stress resistance of the wire harness is effectively improved, making it not easily damaged during operations such as bending and stretching; the sealing and firmness of the wire harness are enhanced to prevent external factors from eroding the wire harness; the protection performance of the wire harness is improved, the service life of the wire harness is extended, the production cost is reduced, and the market competitiveness of the wire harness product in different application scenarios is improved.

[0078] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways.
