Abstract

The flocked skylight stay wire comprises a wire layer and a fluff layer, the wire layer comprises a shaft core and an externally-wound steel wire, the externally-wound steel wire is spirally wound on the shaft core, and the peripheral surface of the wire layer is a first concave-convex surface; the fluff layer comprises a plurality of fluff erected on the peripheral face of the thread layer through electrostatic flocking, the fluff is evenly distributed in the circumferential direction of the first concave-convex face, and the peripheral face of the fluff layer is a second concave-convex face. Noise caused by hard friction between the skylight gear and the outer winding steel wire is reduced through the fluff fully covering the outer peripheral surface of the wire layer; and the fluff formed by electrostatic flocking is uniformly distributed, so that the phenomenon of non-uniform fluff distribution caused by winding operation loss is avoided, the resistance fluctuation of the skylight system is effectively reduced, and the operation stability of the skylight system is improved.

Description

Technical Field

[0001] The utility model patent relates to the technical field of automobile accessories and is a flocking sunroof pull wire. Background Art

[0002] The skylight pull wire or flexible shaft with flocking is usually fixed between the spiral gaps of the outer winding steel wire by winding the finished flocking wire and rubber wire, such as the automobile electric skylight flexible shaft device disclosed in CN 201507537 U. The flocking wire or flocking strip set by winding has the following disadvantages: the outer peripheral surface of the outer winding steel wire is not covered with fluff, and the friction sound between the gear and the pull wire is relatively loud during the operation of the skylight; the processing quality and efficiency are low, and the fluff on the flocking wire or flocking strip is easily lost during the winding process, resulting in uneven distribution of the fluff on the outer periphery of the wire layer, causing fluctuations in the resistance of the skylight system, thereby affecting the stability of the product. Utility Model Content

[0003] The utility model aims to solve the existing technical problems and proposes a flocking skylight pull cord.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a flocked skylight pull wire, including a wire layer and a fluff layer, the wire layer includes an axis core and an outer winding steel wire, the outer winding steel wire is spirally wound on the axis core, and the outer peripheral surface of the wire layer is a first concave-convex surface; the fluff layer includes a plurality of fluffs standing upright on the outer peripheral surface of the wire layer through electrostatic flocking, the plurality of fluffs are evenly distributed along the circumference of the first concave-convex surface, and the outer peripheral surface of the fluff layer is a second concave-convex surface; the outer peripheral surface of the wire layer is also provided with a glue layer for curing the fluff.

[0005] Preferably, the fluff is selected from nylon staple fibers with a fineness of 8-10 dtex.

[0006] Preferably, the length of the villi is 0.4-0.6 mm.

[0007] Preferably, the shaft core includes a core wire, a first reinforcement layer and a second reinforcement layer, the first reinforcement layer includes a plurality of first steel wires spirally wound side by side on the core wire, and the second reinforcement layer includes a plurality of second steel wires spirally wound side by side on the periphery of the first reinforcement layer.

[0008] Preferably, the winding spacing of the outer winding steel wire on the shaft core is 2-3 mm.

[0009] The beneficial effects of the utility model are: the noise caused by the hard friction between the sunroof gear and the outer winding steel wire is reduced by the fluff that fully covers the outer circumference of the wire layer; the fluff formed by electrostatic flocking is evenly distributed, avoiding the uneven distribution of fluff caused by winding operation wear, effectively reducing the resistance fluctuation of the sunroof system, and improving the operating stability of the sunroof system.

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0014] Combined with the embodiments and Figure 1-3 A flocked skylight pull wire includes a wire layer and a fluff layer. The wire layer includes an axis core 11 and an outer winding steel wire 12. The outer winding steel wire 12 is spirally wound on the axis core 11. The outer peripheral surface of the wire layer is a first concave-convex surface. The fluff layer includes a plurality of fluffs 2 standing upright on the outer peripheral surface of the wire layer by electrostatic flocking. The plurality of fluffs 2 are evenly distributed along the circumference of the first concave-convex surface. The outer peripheral surface of the fluff layer is a second concave-convex surface 20. The wire layers are all made of metal material.

[0015] The outer peripheral surface of the thread layer is coated or sprayed with a glue layer for curing the fluff 2 to improve the anti-shedding performance of the fluff.

[0016] The fluff 2 is selected from nylon 66 staple fibers with a fineness of 8-10 dtex, and the length of the fluff is 0.4-0.6 mm.

[0017] The shaft core includes a core wire 111, a first reinforcement layer and a second reinforcement layer. The first reinforcement layer includes a plurality of first steel wires 112 spirally wound side by side on the core wire, and the number of the first steel wires 112 is 4-6; the second reinforcement layer includes a plurality of second steel wires 113 spirally wound side by side on the outer periphery of the first reinforcement layer, and the number of the second steel wires 113 is 4-6. The spiral winding direction of the first steel wire is the same as the spiral winding direction of the outer winding steel wire, and the spiral winding direction of the second steel wire is opposite to the spiral winding direction of the first steel wire.
