The shoelace elastic assembly 100 is used to contract or loosen shoelaces. The shoelace elastic assembly 100 includes a shoelace base 10 and a shoelace elastic module 20. The shoelace elastic module 20 is arranged on the outer side of the shoelace base 10.

[0040] In the embodiment of the present application, the shoelace base 10 serves as a supporting component of the shoelace tensioning assembly 100. The shoelace base 10 is used to support the shoelace tensioning module 20. The shoelace base 10 is used to fit or sew the wearable body so that the shoelace base 10 is fixed to the wearable body, thereby facilitating the connection of the entire shoelace tensioning assembly 100 with the wearable body through the shoelace base 10.

[0041] In the embodiment of the present application, the shoelace tensioning module 20 includes a snap-fit ​​seat 21, a shoelace tensioning wheel 22, and a rotating cover 23; the snap-fit ​​seat 21 is snap-fitted to the shoelace base 10, and supports the shoelace tensioning wheel 22 and the rotating cover 23, so that the shoelace tensioning module 20 is snap-fitted and connected with the shoelace base 10 through the snap-fit ​​seat 21; the shoelace tensioning wheel 22 is in the snap-fit ​​seat 21, and is rotatably mounted on the snap-fit ​​seat 21, so as to adjust the position of the shoelace tensioning wheel 22 relative to the snap-fit ​​seat 21; the shoelace tensioning wheel 22 is respectively connected to the two ends of the shoelace that is passed through the snap-fit ​​seat 21, and the shoelace is wound around the peripheral side wall of the shoelace tensioning wheel 22 as the shoelace tensioning wheel 22 rotates, and the shoelace is collected, so as to tighten the shoelace;

[0042] At this time, the rotating cover 23 is on the outer peripheral side of the snap-fit ​​seat 21 and can be rotatably connected to the snap-fit ​​seat 21 to facilitate the adjustment of the rotating cover 23 relative to the snap-fit ​​seat 21; the rotating cover 23 is provided with a first annular rack 231 and a first inner tooth portion 232; the first annular rack 231 is plugged into the shoelace tensioning wheel 22 and meshes with the shoelace tensioning wheel 22, so that the shoelace tensioning wheel 22 rotates with the rotation of the rotating cover 23, and the shoelaces are wound around the peripheral side wall of the shoelace tensioning wheel 22 with the rotation of the shoelace tensioning wheel 22, and the shoelaces are wound around the peripheral side wall of the shoelace tensioning wheel 22, thereby achieving the shoelace winding effect.

[0043] At the same time, the first inner tooth portion 232 is located outside the first annular rack 231 and is elastically engaged with the engaging seat 21 to prevent the rotating cover 23 from reversing and avoids the line returning due to the reversal, thereby further ensuring the shoelace winding effect.

[0044] At this time, the locking seat 21 includes a locking seat body 211 and an elastic thorn wheel 212; the elastic thorn wheel 212 is arranged along the annular direction of the locking seat 21; the elastic thorn wheel 212 is elastically connected to the locking seat body 211, and meshes with the first inner tooth portion 232 to limit the reversal of the first inner tooth portion 232, so that the rotating cover 23 can be meshed and connected with the first inner tooth portion 232 through the elastic thorn wheel 212, thereby preventing the reversal of the rotating cover 23, avoiding the return of the line due to the reversal, and further ensuring the shoelace winding effect.

[0045] Among them, there are multiple elastic thorn wheels 212, and the multiple elastic thorn wheels 212 are arranged in sequence along the annular direction of the snap-fit ​​seat 21. By arranging multiple elastic thorn wheels 212, the meshing stability of the elastic thorn wheels 212 relative to the first inner tooth portion 232 is increased, thereby facilitating the increase of the traction force of the snap-fit ​​seat 21 relative to the rotating cover 23; the shoelace tensioner 22 is rotatably connected to the snap-fit ​​seat body 211 and is located at the lower side of the multiple elastic thorn wheels 212, so as to facilitate the adjustment of the position of the shoelace tensioner 22 relative to the snap-fit ​​seat body 211. As the shoelace tensioner 22 rotates, the shoelaces are wound around the peripheral side wall of the shoelace tensioner 22, and the shoelaces are wound up, thereby achieving the shoelace winding effect.

[0046] At this time, the shoelace tensioner 22 is provided with a second annular rack 221, and the second annular rack 221 is located in the middle of the multiple elastic spur wheels 212 and meshed with the first annular rack 231, so that the shoelace tensioner 22 can be meshed and connected with the rotating cover 23 through the second annular rack 221 and the first annular rack 231, so that the shoelace tensioner 22 can rotate with the rotation of the rotating cover 23, and the shoelaces can be wound around the peripheral side wall of the shoelace tensioner 22 with the rotation of the shoelace tensioner 22, and the shoelaces can be taken up, thereby achieving the shoelace taking-up effect.

[0047] Among them, the elastic ratchet 212 includes an elastic arm 2121 and a ratchet portion 2122, the elastic arm 2121 extends along the arc direction, one end of the elastic arm 2121 is connected to the snap-fit ​​seat body 211, so that the elastic ratchet 212 is fixedly connected to the snap-fit ​​seat body 211 through the elastic arm 2121, and the other end of the elastic arm 2121 is connected to the ratchet portion 2122, and the ratchet portion 2122 is meshed with the first inner tooth portion 232, so that the elastic ratchet 212 is meshed and connected with the first inner tooth portion 232 through the ratchet portion 2122.

[0048] There is a swing gap between the outer wall of the elastic arm 2121 and the inner wall of the snap-fit ​​seat body 211, so that the first inner tooth portion 232 can pass through the swing gap. The ratchet portion 2122 faces the inner wall of the snap-fit ​​seat body 211, so that the ratchet portion 2122 and the first inner tooth portion 232 can be meshed to avoid reversal of the rotating cover 23, avoid back-threading due to reversal, and further ensure the shoelace winding effect.

[0049] When the rotating cover 23 rotates relative to the locking seat 21, the first inner tooth portion 232 rotates with the rotation of the rotating cover 23, and different positions of the first inner tooth portion 232 contact the ratchet portion 2122 in sequence, so that the first inner tooth portion 232 rotates clockwise to avoid reversal of the rotating cover 23, avoid back-threading due to reversal, and further ensure the lace winding effect.

[0050] The snap-fit ​​seat body 211 is provided with a accommodating cavity 211a, and the shoelace tensioner 22 is located in the accommodating cavity 211a and rotates in the accommodating cavity 211a. The inner contour of the accommodating cavity 211a is gap-matched with the outer contour of the shoelace tensioner 22, so that the shoelace tensioner 22 can rotate through the gap between the inner contour of the accommodating cavity 211a and the outer contour of the shoelace tensioner 22, thereby facilitating the shoelace tensioner 22 to wind up the shoelace during the rotation process.

[0051] A supporting arm 2111 is protruding from the bottom of the snap-fit ​​seat body 211. The supporting arm 2111 is located at the lower side of the shoelace tensioner 22 and supports the shoelace tensioner 22, so that the snap-fit ​​seat body 211 supports the shoelace tensioner 22 through the supporting arm 2111, thereby facilitating the shoelace tensioner 22 to be located on the inner side of the snap-fit ​​seat body 211.

[0052] The outer wall of the snap-fit ​​seat body 211 is provided with a snap-fit ​​boss 2112, which is detachably engaged with the shoelace base 10 so that the snap-fit ​​boss 2112 can be connected to or detached from the shoelace base 10. The shoelace base 10 is provided with a snap-fit ​​groove 10a, and the snap-fit ​​boss 2112 is engaged with the snap-fit ​​groove 10a so that the snap-fit ​​seat body 211 can be snap-fitted and connected with the shoelace base 10 through the snap-fit ​​boss 2112 and the snap-fit ​​groove 10a.

[0053] The elastic arm 2121 is connected to a fixed block 2123, which is engaged with the rotating cover 23 so that the fixed block 2123 limits the position of the rotating cover 23 and prevents the rotating cover 23 from shaking. There are multiple fixed blocks 2123, and the multiple fixed blocks 2123 are arranged at intervals in a circular direction. By arranging multiple fixed blocks 2123, the fixing effect of the fixed block 2123 relative to the rotating cover 23 is increased.
