Description

Technical Field

[0001] This utility model belongs to the field of outdoor equipment technology, and in particular relates to a wind rope light based on a composite braided structure. Background Technology

[0002] Among outdoor gear, tarps, tents, and other similar items are secured with guy lines to create spaces that provide shade and shelter from the rain, making them highly popular among outdoor enthusiasts.

[0003] Traditional wind ropes are mostly single-layer nylon or polyester braided structures, with limited functionality and lack of light-emitting or reflective features, making them prone to tripping pedestrians in low-light conditions. To address these issues, Chinese Utility Model Patent Publication No. CN218623640U discloses an LED luminous camping windproof rope. LED beads, a first conductor, and a second conductor are respectively wrapped with first and second insulating fibers, and a PVC pipe is wrapped with a braided mesh. LED strings and bulletproof wires are arranged side-by-side inside the PVC pipe. However, this design has the following drawbacks: although it possesses a certain tensile strength, the multi-layered structure of the LED beads causes difficulties in heat dissipation and poor light transmission; and in the absence of power, the reflective function is lost, failing to provide passive safety warnings. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a wind rope light based on a composite braided structure.

[0005] The purpose of this utility model can be achieved through the following technical solution: a wind rope light based on a composite braided structure, including a flexible load-bearing unit and a functional braided layer. The flexible load-bearing unit is formed by multiple strands of polypropylene yarn and LED drop lights arranged side by side to form a central composite cable core. The functional braided layer is formed by at least three sets of polyester yarn and reflective yarn using a twill braided structure to cover the outer periphery of the central composite cable core, wherein the reflective yarn is woven between the polyester yarn at equal intervals along the warp direction.

[0006] Preferably, the polyester yarn includes at least two colors, with two sets of black polyester yarns woven along the warp direction on both sides of the reflective yarn.

[0007] Preferably, the twill weave structure of the functional braided layer is a 2 / 2 twill weave structure.

[0008] Preferably, the polyester filament is a 210D high-strength, low-elongation fiber with a weaving density of 8-12 mesh / cm. 2 .

[0009] Preferably, the reflective filament is composed of a prism reflective film coated on the surface of a glass fiber substrate.

[0010] Preferably, the wind rope light is fixed at both ends with adhesive and has end sleeves fitted on the outside.

[0011] Preferably, the LED cord light includes an insulated wire and LED beads, with a plurality of LED beads being equidistantly distributed on the insulated wire.

[0012] Preferably, the spacing between the LED beads is 10-15cm.

[0013] Preferably, one end of the wind rope light is connected to a wind rope buckle, and the other end is connected to a ring buckle.

[0014] Preferably, the insulated wire extends to the outside of the end sleeve and is electrically connected to the power supply unit. This outdoor wind rope light also includes a remote control that is wirelessly connected to the power supply unit.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. Multiple strands of polypropylene yarn are arranged side by side with LED drop lights to form a central composite cable core. The polypropylene yarn serves as the main load-bearing skeleton, realizing the physical integration of mechanical tensile force and circuit function, significantly improving the overall tensile strength and durability.

[0017] 2. Polyester yarn has good light transmittance, which ensures the light-emitting warning performance of LED beads. The heat emitted by LED beads can be dissipated through the warp and weft weave holes of the functional braided layer, which effectively improves the service life of the wind rope light.

[0018] 3. Dual-mode warning mechanism: When powered on, the LED beads emit light evenly, providing a high-visibility warning; when powered off, the reflective filaments embedded in the functional braided layer can reflect the light source, achieving a passive warning without energy consumption.

[0019] 4. Black polyester filaments are arranged on both sides of the reflective yarn to form a "black-reflective-black" sandwich structure. The principle of contrasting colors is used to improve the reflective visibility under low light conditions and eliminate the blind spot problem of traditional reflective materials that rely on directional light sources.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1-3 As shown, this embodiment discloses a wind rope light based on a composite braided structure, including a flexible load-bearing unit 1 and a functional braided layer 2. The flexible load-bearing unit 1 is formed by multiple strands of polypropylene filaments 11 and LED drop lights 12 arranged side by side to form a central composite cable core. The functional braided layer 2 is formed by at least three sets of polyester filaments 21 and reflective filaments 22 using a twill braided structure to cover the outer periphery of the central composite cable core, wherein the reflective filaments 22 are woven at equal intervals between the polyester filaments 21 along the warp direction.

[0027] The central composite cable core is formed by multiple strands of high-tensile-strength polypropylene filaments 11. LED drop lights 12 and polypropylene filaments 11 are arranged side-by-side to form the central composite cable core. Multiple sets of highly weather-resistant polyester filaments 21 and reflective filaments 22 are wrapped around the central composite cable core in a twill braid structure, forming a high-strength composite braid structure. Reflective filaments 22 serve as an outer auxiliary warning material. The ductility of polypropylene filaments 11 is far lower than that of the conductive metal wires inside the LED drop lights 12. Therefore, polypropylene filaments 11 and polyester filaments 21 primarily bear the mechanical tension, while the light string only needs to meet the requirements of flexible circuitry, avoiding the problem of circuit breakage due to insufficient tension or separation of the load-bearing structure in traditional light ropes. When powered on, the LED beads on the LED drop lights 12 emit light as a warning; when powered off, the reflective filaments 22 reflect light sources such as car lights, flashlights, and natural light. This active and passive dual-mode warning solves the single-warning defect of existing wind ropes and effectively improves safety. Polyester filament 21 has good light transmittance, ensuring the light-emitting warning performance of the LED beads on the LED cord light 12. The heat emitted by the LED beads can be dissipated through the warp and weft weave gaps of the functional braided layer 2, effectively improving the service life of the cord light.

[0028] Furthermore, the polyester filaments 21 include at least two colors, with two sets of black polyester filaments 21 woven along the warp direction on both sides of the reflective filaments 22. The reflective filaments 22 are used for passive reflection, forming a "black-reflective-black" sandwich structure. The black polyester filaments 21, as a contrasting color, can enhance the reflective effect, especially under low light conditions.

[0029] The functional woven layer 2 has a 2 / 2 twill weave structure. The twill weave is formed by the float length of the warp and weft yarns (i.e., the number of times the yarn continuously floats on the fabric surface).

[0030] In a 2 / 2 twill weave, the numerator "2" indicates that the warp yarns continuously float above two weft yarns; the denominator "2" indicates that the weft yarns continuously float below two warp yarns. This alternating structure creates a clear diagonal pattern, typically around 45°, with evenly spaced warp and weft interlacing points and a symmetrical structure. The advantages of a 2 / 2 twill weave include resistance to deformation, strong structural stability, maintaining a certain level of tightness while enhancing abrasion resistance, moderate breathability, and a clear and aesthetically pleasing surface texture.

[0031] The polyester filament 21 is made of 210D high-strength, low-elongation fiber with a weaving density of 8-12 mesh / cm². 2 210D high-strength, low-elongation fiber with 8-12 mesh / cm 2 The combination of weaving densities, through multi-scale matching of materials, structure, and function, achieves breakthrough optimization in terms of lightweighting, environmental stability, and process feasibility, making it particularly suitable for complex outdoor scenarios that require long-term tolerance to high humidity and heat and multiple bends.

[0032] like Figure 2 , Figure 4 As shown, in this embodiment, the reflective filament 22 is composed of a glass fiber substrate 22a coated with a prism reflective film 22b. The glass fiber substrate 22a has high strength and load-bearing capacity, and the prism reflective film 22b achieves multiple total internal reflections based on the refraction and reflection of microprisms, with uniform reflective brightness and no blind spots, significantly improving the outdoor safety warning effect.

[0033] Furthermore, the two ends of the wind rope light are fixed with adhesive and end sleeves 3 are sleeved on the outside.

[0034] Adhesive fixing is used to prevent the ends of the wind rope light from loosening. The end sleeve 3 not only achieves reliable fixing and protection of the ends of the rope body and improves the durability of the rope body, but also can integrate various modular interfaces for connecting to the LED wind rope light 12, such as the interface for connecting to the matching power supply, USB power supply interface, etc., and the functions can be effectively expanded.

[0035] The LED drop light 12 includes an insulated wire 12a and LED beads 13, with a plurality of LED beads 13 evenly distributed on the insulated wire 12a. This ensures uniform light while avoiding overly dense LED beads 13 that could cause heat dissipation problems or overly sparse LED beads that could affect brightness. This ensures structural reliability while achieving a precise balance between optical performance and energy efficiency.

[0036] The LED beads 13 are spaced 10-15cm apart.

[0037] One end of the guy line light is connected to a guy line buckle 4, and the other end is connected to a ring buckle 5. The function of the guy line buckle 4 is to adjust the tension of the guy line and fix the tent or tarp, thereby achieving stable wind resistance and structural support. The main function of the ring buckle 5 is to quickly connect outdoor equipment such as tents and tarps, ensuring that they remain stable in the wind.

[0038] The insulated wire 12a extends to the outside of the end sleeve 3 and is electrically connected to the power supply unit 6. This outdoor wind rope light also includes a remote control 7 that is wirelessly connected to the power supply unit 6. The power supply unit 6 and the wind rope light are integrated into one design, making it convenient for outdoor storage and carrying. The remote control 7 is wirelessly connected to the power supply unit 6, improving the ease of operation.

[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
