[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-2 :

[0022] A lighting structure for a sewing machine includes a sewing head 1 and a lighting assembly arranged on the sewing head 1. The sewing assembly is provided at a first end 2 of the sewing head 1, and an electrical control box is connected to a second end 3 of the sewing head 1. A boss 4 is provided on the side of the sewing head 1, extending from the first end 2 to the second end 3. A cover plate 5 adapted to the shape and size of the boss 4 is provided on the outside of the boss 4. A concealed wiring groove 6 is provided between the cover plate 5 and the boss 4. The lighting assembly includes a lamp 7 and a power cord 8. The lamp 7 is located inside the first end 2 of the sewing head 1, and the power cord 8 is embedded in the concealed wiring groove 6. One end of the power cord 8 is electrically connected to the lamp 7, and the other end is electrically connected to the electrical control box.

[0023] In this embodiment, during wiring, the power cord 8 is first inserted along the direction of the concealed wiring groove 6, with a certain installation length reserved at both ends. Then, the cover plate 5 and the boss 4 are fixedly connected by fasteners or other methods. After that, the two ends of the power cord 8 are electrically connected to the lamp 7 and the electrical control box, respectively. Of course, it can also be used to install a lamp 7 with a power cord 8. The lamp 7 is fixed inside the first end 2, and then the power cord 8 is inserted along the direction of the concealed wiring groove 6 from the lamp 7 end to the electrical control box end. The cover plate 5 and the boss 4 are fixedly connected by fasteners or other methods. Finally, the connector of the power cord 8 is electrically connected to the electrical control box.

[0024] In this embodiment, the boss 4 has an externally open groove structure 9. After the cover plate 5 is connected to the boss 4, it closes the groove structure 9 and forms a hidden wiring groove 6.

[0025] Furthermore, at least one set of limiting structures is provided within the groove structure 9. The limiting structures include a limiting groove 10 on the upper wall of the groove structure 9 and a limiting protrusion 11 on the lower wall of the groove structure 9. When the power cable 8 is arranged between the limiting groove 10 and the limiting protrusion 11, it forms a bent structure 12. Preferably, both the limiting groove 10 and the limiting protrusion 11 are arc-shaped structures. The arc shape can reduce stress at the wiring corners and prevent damage to the line due to excessive bending. The limiting structures can hinder the pulling of the power cable 8, preventing the power cable 8 from sliding along the concealed wiring groove 6, thereby making the installation of the power cable 8 more stable.

[0026] Preferably, the distance between the limiting groove 10 and the limiting protrusion 11 is less than the distance between the upper wall and the lower wall of the groove structure 9.

[0027] Comparison Appendix Figure 2 In this embodiment, a segmented wiring structure is adopted. Specifically, the power cord 8 includes a front exposed wire segment 13 at the front end, a hidden wiring segment 14 in the middle main body, and a rear exposed wire segment 15 at the rear end. The hidden wiring segment 14 is the main body segment. The front exposed wire segment 13 is electrically connected to the lamp 7. The hidden wiring segment 14 is located in the hidden wiring groove 6. The rear exposed wire segment 15 is electrically connected to the electrical control box. In this utility model, the main body segment refers to a segment whose length is more than half of the total length.

[0028] To reduce stress at wiring corners and prevent damage to the wiring due to excessive bending, the corners of the concealed wiring trough 6 are all rounded.

[0029] In this embodiment, the lamp 7 is an LED lamp.

[0030] Furthermore, the inner side of the first end 2 of the machine head 1 is set as a slope 16, the lamp 7 is installed on the slope 16, the outlet end of the hidden wiring groove 6 near the lamp 7 is set as an inclined outlet 17 with the slope of the slope 16, and the front bright line segment 13 is wired along the outer contour of the slope 16.

[0031] Furthermore, the concealed wiring groove 6 is located at the bottom of the boss 4 near the outlet end of the electrical control box and extends downward into an expansion groove 18, and the exposed wire segment 15 is wired along the bottom contour of the boss 4.

[0032] The aforementioned inclined outlet 17 and expansion slot 18 structures can also reduce the stress at wiring corners and prevent the lines from being damaged due to excessive bending.

[0033] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
