First embodiment

Referring to fig. 2 to 8, the chain assembly composed of a plurality of first connecting links 41 and second connecting links 42 is used for wearing connection of wearable equipment, and is disposed below the flexible screen assembly; the first connecting links 41 and the second connecting links 42 are arranged at intervals, and each second connecting link 42 is positioned at the top of the first connecting link 41 and movably connected with the adjacent first connecting link 41; the two ends of the first connecting link 41 along the length direction of the chain assembly are respectively provided with a boss and a groove, and the shapes of the boss and the groove are matched; the projection of a first connecting link 41 projects into the recess of an adjacent first connecting link 41.

The chain assembly in this embodiment is arranged below the flexible display screen and is used for achieving a wearing function and bearing the flexible display screen. The parameters such as the length and the width of the whole chain assembly can be set according to specific requirements during production, for example, a longer and wider chain assembly can be set for a male user so as to be convenient to wear, or the sizes of the chain assemblies matched with different age groups can be produced and designed. The size of the chain assembly can be set according to the size and the number of the connecting links.

In this embodiment, the chain assembly is implemented by the composition between two connecting links. The two types of connecting links are divided into a first connecting link 41 and a second connecting link 42, the first connecting link 41 and the second connecting link 42 are distributed at intervals, that is, the second connecting link 42 is arranged between the adjacent first connecting links 41 and connected with the first connecting link 41, and the first connecting link 41 is arranged between the second connecting links 42 and connected with the first connecting link 41. The first connecting link 41 and the second connecting link 42 in the present embodiment are spaced apart from each other only by the connecting relationship between the first connecting link 41 and the second connecting link 42, and not by the spatial position relationship therebetween, which is not completely consistent although the spatial position relationship has some relation with the connecting relationship. Specifically, the first connecting link 41 is located at a spatial position substantially at the bottom of the completed chain assembly, while the second connecting link 42 is located at the top of the chain assembly; equivalently, the first connecting link 41 is disposed at a lower portion of the second connecting link 42, and an upper portion of the first connecting link 41 is movably connected to the second connecting link 42. The length direction referred to in this embodiment refers to the length direction of the chain assembly, the width direction refers to the width direction of the chain assembly, and the height direction refers to the height direction of the chain assembly, the length direction refers to the extending direction of the chain assembly when not in use, and the width direction refers to the direction perpendicular to the length direction on the chain assembly, and the plane formed by the length direction is parallel to the chain assembly and the flexible screen assembly 2 located above the chain assembly, and the size in the direction does not change along with the bending and unfolding of the chain assembly; the height direction is the direction representing the thickness of the chain assembly.

The connecting direction between the adjacent first connecting link 41 and second connecting link 42 is consistent and corresponds to the length direction of the chain assembly. The movable connection between the first connecting link 41 and the second connecting link 42 is to allow the chain assembly to be switched between a straight state and a bent state, that is, the first connecting link 41 and the second connecting link 42 can be bent, and further drive the chain assembly and even the flexible screen assembly 2 located on the chain assembly to also be bent correspondingly; during the bending process, the position relationship between the adjacent first connecting link 41 and the second connecting link 42 may be changed, and specifically, the distance between the adjacent first connecting link 41 and the adjacent second connecting link 42 in the bent state may be smaller than the distance between the adjacent first connecting link 41 and the adjacent second connecting link 42 in the flat state. This is because the flexible screen assembly 2 is disposed above the chain assembly, so that when the flexible screen assembly 2 is bent, the size of the flexible screen assembly 2 is actually elongated to a certain extent compared to a straight state, and accordingly, the chain assembly carrying the flexible screen assembly 2 is shortened to a certain extent, which is reflected on the first connecting link 41 and the second connecting link 42, that is, the adjacent first connecting link 41 and the second connecting link 42 are close to each other in relative position.

In the use process of the wearable device, considering the bending limit of the flexible screen module 21 in the flexible screen assembly 2, damage of the flexible screen module 21 due to excessive bending is avoided, or damage of other components in the wearable device due to scenes such as excessive bending and abnormal bending angles is avoided, in this embodiment, on the first connecting link 41, two ends in the length direction of the chain assembly are respectively provided with a boss 413 and a groove 414, and the shape of the boss 413 is matched with that of the groove 414; boss 413 of a first connecting link 41 extends into recess 414 of an adjacent first connecting link 41. The shape of the boss 413 is matched with that of the groove 414, referring to the drawings, the boss 413 in the present embodiment is a trapezoidal protrusion, and the groove 414 is also a trapezoidal groove; in the straight state, each boss 413 and the groove 414 are arranged with equal gaps, and in the bending state, the adjacent bosses 413 are close to the grooves 414, and the bosses 413 extend into the adjacent grooves 414. In the flat state, a certain distance is provided between the adjacent first connecting links 41 and between the boss 413 and the groove 414, and the size of the distance determines the limit distance of the wearable device in the bent state, in other words, when the wearable device is bent to the limit state, the boss 413 extends into the groove 414 and is tightly attached to the wall of the groove 414 between the adjacent first connecting links 41, so as to prevent the wearable device from being bent further; in addition, the arrangement of the boss 413 and the groove 414 can also prevent the chain assembly, or the wearable device, from bending in the width direction, in this scenario, the boss 413 may directly contact the side wall of the groove 414 to prevent the groove 414 from bending, that is, the anti-twisting function may be performed. These two kinds of effects can all be followed the angle of avoiding chain subassembly to take place abnormal buckling, further protect flexible screen module 21 to the life of wearable equipment is prolonged.

In some embodiments, the first connecting links 41 are hollow structures, and the hollow structures of the first connecting links 41 are through; the first connecting link 41 is further provided with a partition 415 therein, and the partition 415 divides the first connecting link 41 into a first chamber and a second chamber in the height direction.

The power steel sheet 3 is a thin steel sheet, also called as a snap ring, and generally has two states, one of which is a straight state, in which the cross section of the power steel sheet 3 is arc-shaped, and once the balance in the straight state is broken, for example, a user beats through knocking, and then beats on a wrist, the balance can be broken to bend the power steel sheet 3, the bending direction is bending towards the arc-shaped direction of the cross section of the power steel sheet 3, after bending, the arc-shaped form of the power steel sheet 3 is weakened and becomes more flat, and the closer to the center of the power steel sheet 3 in the length direction, the more so. Through setting up power steel sheet 3, can promote the convenience that the user wore, also can promote the taste of wearing, and utilize power steel sheet 3's straight state, operation such as can be better shoot again. In this embodiment, the outer surface of the power steel sheet 3 is coated with a layer of silica gel, which is used to protect the power steel sheet 3 from scratching the inner walls of the first connecting link 41 and the second connecting link 42, and prolong the service life of the power steel sheet.

In some embodiments, the first connecting link 41 and the second connecting link 42 form a rotation connection through a pin and a pin hole, and the rotation axis of the rotation connection is adjustable. Specifically, in some embodiments, the first connecting link 41 is provided with first pin holes 411 at two ends along the width direction of the chain assembly, and the first pin holes 411 are runway holes; the second connecting link 42 is provided with a second pin hole; the pin 412 sequentially passes through the first pin hole 411 at one end of the first connecting link 41, the second pin hole of the second connecting link 42, and the first pin hole 411 at the other end of the first connecting link 41 to form a rotary connection. The hole shaft matching through setting up runway hole and pin 412 forms to rotate to be connected, and the center of rotation that should rotate to connect can change along with pin 412 downthehole translation of runway to can guarantee that the buckling of chain subassembly is smooth and easy.
