As shown in fig. 1 to 6, in order to improve the operation and visual experience of a user using an intelligent wearable device, especially an intelligent watch and an intelligent bracelet, the present embodiment provides an intelligent wearable device with a telescopic function of a screen 20, the intelligent wearable device is mainly for wearing a wrist, and includes a wrist ring 10 worn by the user, the wrist ring 10 has a first ring body 12 in a planar structure and a second ring body 13 fixed at one end of the first ring body 12, a sliding groove 11 is formed on a surface of the wrist ring 10 along a circumferential direction of the wrist ring, the screen 20 is movably fitted on the sliding groove 11, in practical applications, when the user lifts his hand to observe the screen 20 placed on the sliding groove 11, a part of the sliding groove 11 faces the user, another part extends along a length direction of the wrist ring 10, and a lower part refers to a direction in which the user is located at a lower part of the intelligent device when lifting his hand to observe, so that the same part of the screen 20, the other part is arranged in the sliding groove 11 at the lower part, in the state, the intelligent wearable device is in a small screen 20 mode, and can be set through a program, in the mode, only the screen 20 facing to the user part carries out the visualization work, and the screen 20 at the lower part is in a dormant state, so that the energy consumption of the intelligent wearable device is reduced.

In this example, the use state refers to a state where the user performs an action similar to looking at a watch or a bracelet while raising the hand.

An opening 111 is formed at one end of the sliding chute 11, in a use state, the opening 111 is located at the upper portions of the sliding chute 11 and the screen 20, the screen 20 can move in a reciprocating manner in the setting direction of the sliding chute 11, and at the same time, a part of the screen extends out of the sliding chute 11 from the opening 111, the setting range of the screen 20 on the wrist ring 10 can at least cover all the first ring body 12 and part of the second ring body 13, so that a part of the screen 20 originally placed on the sliding chute 11 extends out of the wrist ring 10 from the opening 111, and the screen 20 originally placed at the lower portion of the wrist ring 10 moves towards the opening 111 along with the movement of the screen 20 to a position close to the opening 111, so that the screen 20 extends out of the wrist ring 10 partially and is placed in a moving portion facing towards a user, the screen 20 extending out of the opening 111 is preferably parallel to the screen 20 still placed in the moving portion, thereby ensuring that the screen 20 faces towards the user, and increasing the area of the screen 20 facing the user, switch into large screen 20 mode, for the scheme that the tradition adopted folding mode to increase screen 20 towards user's area, this scheme need not fold screen 20, consequently under large screen 20, also can not have crease or frame, clearance between screen 20 and the screen 20 on the screen 20, thereby improved this intelligence wearing equipment's an organic whole nature, improve user's use, the operation impression, and under large screen 20 mode state, the screen 20 that stretches out uncovered 111 part and the screen 20 part that is in on first ring body 12 realize the function of developing jointly, reach the effect of large screen 20.

As a specific embodiment of the above solution, the chute 11 includes a first section 112 and a second section 113, the first section 112 is connected to and communicated with one end of the second section 113, and the opening 111 is disposed on the first section 112 and is located at one end of the first section 112 far from the second section 113.

In this example, in the use state of the smart wearable device, the first ring 12 faces the user, and accordingly, the first segment 112 also faces the user, and both the second ring 13 and the second segment 113 are located at the lower portion of the support wearable device.

The ring body generally has two structures, and for the convenience of understanding, the two structures are used as references of relative positions in a use state:

in the structure 1, one end of a first ring body 12 is connected with one end of a second ring body 13, the second ring body 13 is connected with the lower part of the first ring body 12, the other end of the second ring body extends to the other end of the first ring body 12 in an annular shape, and a gap is formed between the other end of the first ring body 12 and the other end of the second ring body 13;

the structure 2 and the two opposite ends of the first ring body 12 are connected with the two ends of the second ring body 13 to form a closed ring structure, which is adopted by the wrist ring 10 in this example.

First ring member 12 is formed with kink 14 between the second ring member 13, and one side that spout 11 was kept away from to first ring member 12 is buckled towards second ring member 13 direction along kink 14 to make form corresponding contained angle between first section 112 and the second section 113, through above-mentioned structure, can let unable complete annular structure of formation between first end and the second section 113, avoid it rotatory around user's wrist under wearing state, lead to the unable user that faces of screen 20 under the user state, need dial the condition with the hand.

In addition, in order to keep the screen 20 facing the user in the use state, the first ring body 12 in this embodiment is a straight plate structure, so that the screen 20 on the first ring body 12 is not deformed and bent, thereby providing a better visual effect, and the first ring body 12 can also function to fit the back of the wrist of the user, thereby further stabilizing the state of the wrist ring 10 on the wrist.

The screen 20 of the present scheme includes, but is not limited to, two schemes:

in the scheme 1, the screen 20 is a flexible screen as a whole, and the screen 20 is arranged in the sliding groove 11 along the surfaces of the first ring body 12 and the second ring body 13 as a whole;

scheme 2, the screen 20 comprises a hard screen section 22 and a flexible screen section 23, the hard screen section 22 is arranged on a first section 112, the flexible screen section 23 can move back and forth between the first section 112 and a second section 113, so as to drive the hard screen section 22 to move back and forth between a convex opening or a concave opening 111, in the small screen 20 mode, the hard screen section 22 is disposed in the sliding groove 11 of the first ring body 12, the flexible screen section 23 is disposed in the sliding groove 11 of the second ring body 13, since the first ring segment is preferably a straight plate structure, the rigid screen segment 22 is also selected to be a straight plate screen, when the screen 20 extends out of the opening 111, the hard screen segments 22 partially protrude out of the opening 111, because the hard screen is adopted, the extending part can keep a straight state and is ensured to face the user, the flexible screen 23 is also well adapted to the different structural characteristics of the first ring 12 and the second ring 13, and this is the preferred embodiment.
