And optionally, the hinge shaft between the two second links 360, the hinge shaft between the second link 360 and the second slider 322, and the hinge shaft between the second link 360 and the third slider 351 may all be solid shafts or virtual shafts, and the hinge shaft between the two second links 360, the hinge shaft between the second link 360 and the second slider 322, and the hinge shaft between the second link 360 and the third slider 351 are parallel to each other and may all be perpendicular to the plane where the second guide rail 321 and the third guide rail 350 are located.

Alternatively, if the pressure information detected by the sensor 420 indicates that the pressure experienced by the third joint 400 is low or no pressure, and the entire watchband 10 is relatively open with respect to the wrist of the user, the driving assembly 300 may be controlled to drive one of the first joint 100 and the second joint 200 to rotate toward the main surface of the other, so as to put the watchband 10 into the folded state. If the pressure information detected by the sensor 420 indicates that the entire wristband 10 is relatively tight against the user's wrist when the pressure experienced by the third joint 400 is relatively high, the driving assembly 300 may be controlled to drive one of the first joint 100 and the second joint 200 to rotate away from the main surface of the other, so as to bring the wristband 10 into an open state.

In the above embodiment, by providing the matching among the driving member 370, the first guiding rail 311, the first slider 312, the second guiding rail 321, the second slider 322 and the first link 340, the first joint 100 can rotate relative to the second joint 200 by converting the translational motion into the rotational motion, which has good stability and is convenient for reducing the volume. Furthermore, by arranging the third guide rail 350, the third slider 351 and the second connecting rod 360, the third joint 400 can rotate relative to the second joint 200, so that one driving part can drive a plurality of joint units to rotate, which is beneficial to saving cost and simplifying structure.

Alternatively, based on the principle of the above embodiment, the watch band 10 may further include a fourth joint, and the fourth joint unit may be rotatably connected to the first joint 100 or the third joint 400 in a manner similar to the first joint 100 and the second joint 200 in the above embodiment.

As shown in fig. 3 and 4, the first abutting portion 120 includes a first receiving groove 121, the second abutting portion 220 includes a second receiving groove 221, and the driving assembly 300 is at least partially located in the first receiving groove 121 and the second receiving groove 221.

Optionally, the first abutting portion 120 includes two first abutting strips 122 arranged at intervals, the two first abutting strips 122 cooperate to form the first receiving groove 121, and two ends of the first guide rail 311 abut against the two first abutting strips 122 respectively; the second abutting portion 220 includes two second abutting strips 222 arranged at intervals, the two second abutting strips 222 cooperate to form a second receiving groove 221, and two ends of the second guide rail 321 abut against the two second abutting strips 220, respectively.

Optionally, the first guide rail 311 and the two first sliders 312 may be located in the first receiving groove 121, the second guide rail 321 and the two second sliders 322 may be located in the second receiving groove 221, and the main bodies of the two first links 340 may be located in the first receiving groove 121. The bodies of the two second connecting rods 360 may be located in the second receiving grooves 221, which is not limited herein.

In the above embodiment, the first receiving groove 121 is formed by the first abutting portion 120, and the second receiving groove 221 is formed by the second abutting portion 220, so that a part of the driving assembly 300 can be effectively received, which is beneficial to the overall appearance and can protect the driving assembly 300.

In an alternative embodiment, as shown in fig. 1 and 2, the first joint 100 and the second joint 200 are both arcuate joints and the major surface 110 of the first joint 100 and the major surface 210 of the second joint 200 are both inner curved surfaces. By setting the first joint 100 and the second joint 200 as arc joints, the beauty of the entire band 10 can be improved, so that the entire band 10 is more adapted to the wrist of the user.

As shown in fig. 5, the present application also provides a wearable device 1, where the wearable device 1 includes a main unit 20 and the watch band 10 described in any of the above embodiments. Two watchbands 10 are respectively provided at both ends of the body unit 20.

Alternatively, the driving element in the driving assembly 300 may be disposed on the watch band 10, or may be disposed on the main unit 20, which is not limited herein.

To sum up, this application is through setting up drive assembly 300 for one of drive first joint 100 and second joint 200 rotates towards another's main surface, so that watchband 10 gets into the folded state, or drive one of second joint 100 and second joint 200 and keep away from another's main surface and rotate, so that watchband 10 gets into the open state, thereby can automize and adjust the elasticity of watchband, thereby improve user experience. And through the cooperation that sets up between driving piece 370, first guide rail 311, first slider 312, second guide rail 321, second slider 322 and the first connecting rod 340, can convert translational motion into rotary motion to make first joint 100 rotatory relative to second joint 200, compare and adopt the rotating electrical machines direct drive first joint 100 to rotate relative to second joint 200, have better steadiness, and be convenient for reduce the volume. Furthermore, by arranging the third guide rail 350, the third slider 351 and the second connecting rod 360, the third joint 400 can rotate relative to the second joint 200, so that one driving part can drive a plurality of joint units to rotate, which is beneficial to saving cost and simplifying structure. Furthermore, the first abutting portion 120 and the second abutting portion 220 are arranged to limit the rotation range of the first joint 100 to the second joint 200, so that on one hand, the driving assembly 300 can be effectively protected to prevent the driving assembly 300 from being damaged by too large range, and on the other hand, the wrist of the user can be protected to prevent the first joint 100 from rotating too much towards the second joint 200, which results in the fact that the whole watchband 10 is excessively folded and hurt the user.
