First embodiment

The present embodiment provides a link assembly for a wearable link of a wearable device, as shown in fig. 3, the link assembly 30 includes at least two links 31, and a connecting member 32 matching with the number of the links 31, the connecting member 32 is disposed between two adjacent links 31, specifically, the links 31 and the connecting member 32 are connected by pins in a staggered manner, and every two links 31 are connected by the connecting member 32. The link 31 and the connecting member 32 are connected by a pin, that is, a plurality of links 31 are connected by a pin and the connecting member 32, and an overlapping region exists between the connecting member 32 and the link 31 to ensure the stability of the link assembly 30.

The connecting member 32 in this embodiment includes a connecting portion 321, and first extending portions 322 extending along two sides of the connecting portion 321 to the height direction of the connecting portion 321, where the first extending portions 322 include a first limiting hole 322a and a limiting runway hole 322b located above the first limiting hole 322 a; wherein the height direction refers to the longitudinal axis direction of the connecting portion 321; as shown in fig. 4, fig. 4 is a schematic structural diagram of a connecting member provided in this embodiment.

As shown in fig. 5, fig. 5 is a schematic structural view of the chain link provided in this embodiment, the second limiting hole 311a corresponds to the first limiting hole 322a and the limiting runway hole 322b, and specifically, the second limiting hole 311a corresponds to the first limiting hole 322a and the limiting runway hole 322 b.

The movable connection between the chain link 31 and the connecting piece 32 is limited by the matching between the pin and the limiting hole and the limiting runway hole 322 b. Specifically, in this embodiment, the movable connection is a rotating connection. By rotational connection is meant that the connection between adjacent links 31 and connecting members 32 is at least rotational, which also allows a range of allowed translational movements between adjacent links 31 and connecting members 32; as shown in fig. 3, the first limiting hole 322a and the second limiting hole 311a are rotatably connected by a pin, the limiting runway hole 322b is translationally connected with the second limiting hole 311a by a pin, and the pin can move in the limiting runway hole 322b to realize extension and retraction between the connecting plates, so that the link assembly 30 can be changed from a straight state when not being worn to a bent state when being worn, or from the bent state when being worn to the straight state when not being worn; wherein, when the chain link component 30 is bent and limited in the positive direction, the pin moves in the limiting runway hole 322b, and the positive bending and limiting are carried out in the limiting runway hole 322b, and the chain link component is prevented from bending too much; meanwhile, the links 31 do not directly participate in the movement due to the relative movement of the connecting plates, so that the links 31 do not need to be responsible for positive bending.

In some embodiments, the pin may be a component independent from the link 31 and the connecting member 32, or may be fixed on a limiting hole and attached to the link 31 in the form of a limiting post, specifically, the limiting post of the second extension 311 is formed by fixedly connecting the pin in the second limiting hole 311a of the second extension 311 of the link 31, the fixed connection includes but is not limited to gluing, welding, interference fit, and the like, of course, the position of the limiting post corresponds to the first limiting hole 322a and the limiting runway hole 322b, and the size of the limiting runway hole 322b is larger than that of the limiting post, thereby achieving the reach connection with the first limiting hole 322a and the limiting runway hole 322b through the limiting post.

It should be noted that, in the present embodiment, the pin is taken as an example to be described separately from the link 31, as shown in fig. 5, the link 31 further includes a third extending portion 312 extending along the second extending portion 311 toward the inside of the second extending portion 311, and an arc-shaped link plate 313 extending along the third extending portion 312 toward the height direction of the third extending portion 312, the length of the arc-shaped link plate 313 is smaller than the length between the third extending portions 312, and the second extending portion 311, the third extending portion 312, and the arc-shaped link plate 313 are integrally formed to ensure the integrity of the link 31. Specifically, the upper ends of the second extending portions 311 on both sides are bent inward by 90 degrees and then extend for a certain distance to obtain third extending portions 312, and a gap exists between the third extending portions 312 on both sides; since the length of the arc-shaped link plate 313 extending upward from the outermost end of the third extension 312 is smaller than the length of the arc-shaped link plate 313 from the outermost end of the third extension 312, there is a gap between the arc-shaped link plate 313 and the second extension 311, and the gap serves to allow the link 31 to be properly bent forward when the link assembly is bent forward.

The second extending portion 311 includes four second limiting holes 311a with the same size, the four second limiting holes 311a are divided into two rows, the arrangement relationship may be the opposite arrangement, or the staggered arrangement, as shown in fig. 5, and the second limiting holes 311a in the two rows and two columns are arranged opposite to each other up and down, left and right; in some embodiments, as shown in fig. 6, the four second position-limiting holes 311a in two rows and four columns may be disposed in an offset manner.

As shown in fig. 4, the connecting member 32 includes a connecting portion 321, the connecting portion 321 is a straight rectangle, two ends of the connecting portion 321 are bent and extended forward 90 to form a first extending portion 322, and the connecting portion 321 and the first extending portion 322 are integrally formed to ensure the integrity of the connecting member 32; the first extension portion 322 includes two first position-limiting holes 322a with the same size, and also includes two position-limiting runway holes 322b with the same size, and the outermost end of the position-limiting runway hole 322b is located right above the first position-limiting hole 322 a; of course, the specific length of the stop track hole 322b can be flexibly set according to the length of the actual second extension part 311. As shown in fig. 7, fig. 7 is a side view of the link and the connecting member, two first position-limiting holes 322a are corresponding to two second position-limiting holes 311a, and the two second position-limiting holes 311a are respectively located in two position-limiting runway holes 322 b.

In some embodiments, as shown in fig. 8, fig. 8 is another side view of the link and the connecting member of this embodiment, and the connecting member 32 has substantially the same structure as that of fig. 4, except that the first extending portion 322 includes two first position-limiting holes 322a having the same size, and further includes a position-limiting runway hole 322b, and the position-limiting runway hole 322b is located at a middle position right above the two first position-limiting holes 322 a. At this time, the structure of the link 31 is as shown in fig. 6, two first position-limiting holes 322a correspond to two second position-limiting holes 311a, and the two second position-limiting holes 311a are located in the position-limiting runway holes 322 b.

In this embodiment, the heights of the first extension portions 322 and the second extension portions 311 are the same, but the length between the first extension portions 322 is greater than the length between the second extension portions 311, so that the first extension portions 322 are located outside the second extension portions 311, which facilitates the connection of the link 31 supported by the connection member 32 and the connection with other components of the wearable device through the connection portion 321 of the connection member 32. As shown in fig. 9, fig. 9 is a cross-sectional view of the chain link assembly at the pin, the connecting member 32 supports the chain link 31, and as can be seen from fig. 9, in this embodiment, the pin passes through the limiting hole and the limiting channel hole from the inside of the chain link assembly, and the end of the pin is flush with the limiting hole and the limiting channel hole, so that the integrity of the chain link assembly is not damaged, and a good wearing experience is brought to a user.
