[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] Reference Figure 1A light-emitting edging strip includes: a core strip 500, a fabric layer 100 and a reference structure 200, wherein the core strip 500 can guide light; the fabric layer 100 includes a covering portion 130 and an extension portion 150, wherein the covering portion 130 surrounds and covers the outer periphery of the core strip 500, and the extension portion 150 is arranged on the outer periphery of the covering portion 130 and extends in a direction away from the core strip 500; at least part of the end of the core strip 500 extends out of the covering portion 130, and the covering portion 130 is light-transmissive; the reference structure 200 is arranged on the surface of the extension portion 150, and the reference structure 200 can form a visible outer contour on the surface of the extension portion 150. After the light source 900 illuminates the portion of the core strip 500 extending out of the covering portion 130, the core strip 500 will transmit the light irradiated by the light source 900 through its light-guiding ability, so that the core strip 500 as a whole emits light. Since the covering portion 130 is light-transmissive, when the core strip 500 is luminous, the light it transmits can penetrate the covering portion 130 and be observed by the operator performing the sewing operation. Therefore, the operator performing the sewing operation can clearly and accurately grasp the position and shape relationship of the edging strip during the sewing operation, thereby ensuring that the sewing operation can be carried out smoothly and accurately. Since the reference structure 200 forms a visible outer contour on the surface of the edge portion, during the sewing process, the edging strip can be positioned for sewing connection by using the visible portion of the reference structure 200, thereby ensuring that the connection operation between the edging strip and other parts of the seat can be carried out more smoothly and effectively.

[0027] In certain embodiments, reference Figure 2 The covering portion 130 and the extension portion 150 are an integrated structure. The middle portion of the fabric layer 100 is bent relative to the core strip 500 to form the covering portion 130, and the two ends of the fabric layer 100 are welded or glued to form the extension portion 150. The covering portion 130 and the extension portion 150 are integrally formed under the bending and welding of the fabric layer 100, so the formed covering portion 130 and the extension portion 150 have better integrity and stability, and can effectively avoid the problem of misalignment between the two during the sewing process.

[0028] It is conceivable that the covering portion 130 and the extension portion 150 may be independent components, and after the covering portion 130 surrounds the core strip 500, the extension portion 150 is connected to the periphery of the covering portion 130. The specific composition of the fabric layer 100 is not unique, but can be adjusted accordingly according to actual conditions, and is not limited here.

[0029] In certain embodiments, reference Figure 3The fabric layer 100 is welded or glued at the junction of the covering portion 130 and the extension portion 150. The fabric layer 100 is welded at the junction of the covering portion 130 and the extension portion 150, which can not only effectively ensure that the covering portion 130 after welding can firmly surround the core strip 500, but also can relatively divide the covering portion 130 and the extension portion 150 by the welding position, so as to facilitate the identification and separate use of the covering portion 130 and the extension portion 150 during sewing.

[0030] Specifically, the fabric layer 100 is connected by ultrasonic welding at the junction of the covering portion 130 and the extension portion 150. Of course, the fabric layer 100 can also be connected between the covering portion 130 and the extension portion 150 by other methods, such as adhesive connection or high-frequency welding. The specific connection method is not unique, but can be adjusted accordingly according to actual conditions, and is not limited here.

[0031] In certain embodiments, reference Figure 3 The reference structure 200 includes a welding mark 250 formed between the covering portion 130 and the extension portion 150, and the welding mark 250 is recessed relative to the surface of the extension portion 150. The welding mark 250 recessed relative to the surface of the extension portion 150 can smoothly and effectively form a visible contour on the surface of the extension portion 150 through ups and downs. Therefore, the operator of the sewing work can distinguish between the covering portion 130 and the extension portion 150 through the welding mark 250, which makes it easier for the operator to sew the two separately during the sewing operation.

[0032] It is conceivable that the reference structure 200 may also be composed of other components, such as a strip-shaped protrusion having a color different from that of the extension portion 150. The specific implementation method may be adjusted accordingly according to actual needs and is not limited here.

[0033] In certain embodiments, reference Figure 3 There are multiple welding marks 250, and each welding mark 250 is separated from each other by the extension part 150. Multiple welding marks 250 can make the fabric layer 100 as a whole obtain welding effects at multiple locations, thereby ensuring that the edge strip after welding has better stability and avoiding the loosening phenomenon.

[0034] In certain embodiments, reference Figure 3 The welding marks 250 are arranged equidistantly in a horizontal row parallel to the center line of the core bar 500. The horizontal row formed by the welding marks 250 is parallel to the center line of the core bar 500, so the covering part 130 can be smoothly limited to be flush with the core bar 500, thereby ensuring that the covering part 130 and the core bar 500 are not prone to relative shaking, thereby improving the installation stability of the core bar 500.

[0035] In certain embodiments, reference Figure 3 The fabric layer 100 is bent to form extensions 150 at both ends, and the two extensions 150 are welded or glued together at the edges away from the core strip 500. The welding or gluing between the two extensions 150 can effectively improve the overall firmness of the edge strip, and the welding or gluing effect at the edge can effectively seal the gap between the two extensions 150, thereby preventing problems such as foreign matter and contamination.

[0036] Specifically, the two extensions 150 are connected by ultrasonic welding. Of course, the two extensions 150 can also be connected by other methods, such as adhesive connection or high-frequency welding. The specific connection method is not unique, but can be adjusted accordingly according to actual conditions, and is not limited here.

[0037] In certain embodiments, reference Figure 2 , the edge of the extension part 150 away from the core strip 500 is provided with a cutout 300, and the two extension parts 150 are flush with each other at the cutout 300. When the edging strip is bent along the curved contour of the seat, the edging strip will bend along with it. During the bending process of the edging strip, the edging strip will deform at the cutout 300 and shrink or expand the cutout 300. The existence of the cutout 300 makes the edging strip have a clear deformation point when deformed, and the deformation at the cutout 300 will hardly produce wrinkles, so it can effectively improve the wear resistance of the edging strip and its connecting part 100, and beautify the overall appearance.

[0038] In certain embodiments, reference Figure 2 The cutout 300 is in a sawtooth shape or a wave shape. The sawtooth or wave shape cutout 300 has a plurality of avoidance positions for the edge strip to be deformed, so the bending deformation of the edge strip can be effectively guided and wrinkles on the edge of the edge strip can be avoided.

[0039] In certain embodiments, reference Figure 2 The core strip 500 is flexible. The flexible core strip 500 can be smoothly bent and deformed along the position where the edge strip needs to be surrounded, such as the car seat, so that the edge strip can be smoothly sewn to the car seat and increase its appearance and fixing effect.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
