[0034] See also Figures 1 to 5 The present invention shows a wearable device, which includes a locking device, which may include a first shell 10, a second shell 20 and a sleeve 30. The first shell 10 includes a plate-like body 11 and a receiving portion 12 formed on one side of the plate-like body 11. The receiving portion 12 is columnar, and the inner cavity of the receiving portion 12 forms a receiving cavity A. The circumferential side wall of the receiving portion 12 is provided with a plurality of through grooves 121, and a movable buckle 40 is provided in the through groove 121. The through groove 121 radially penetrates the inner and outer wall surfaces of the receiving portion 12, and the length of the movable buckle 40 may be greater than the length of the through groove 121.

[0035] The sleeve 30 is generally in the shape of a hollow column, such as a hollow cylinder, and can be sleeved on the outer periphery of the accommodating portion 12, and the inner side wall of the sleeve 30 is provided with a groove 31 arranged opposite to the through groove 121. An elastic member 50 is further provided between the sleeve 30 and the plate-like body 11.

[0036] The second housing 20 may include a plate-shaped portion 21 and an insertion portion 22 formed on one side of the plate-shaped portion 21, the insertion portion 22 being used to be inserted into the accommodating cavity A, the insertion portion 22 being coaxially arranged with the accommodating portion 12, and the insertion portion 22 being rotatable along the axis of the accommodating portion 12. Furthermore, an interface 23 for connecting to a terminal is provided on a side of the plate-shaped portion 21 away from the insertion portion 22. The plate-shaped portion 21 and the housing 30 may be connected via a driving structure.

[0037] Combination Figures 6 to 8 As shown, the locking device may include an unlocked state and a locked state. When the locking device is in the unlocked state, the movable buckle 40 is located in the through groove 121 and the groove 31, and does not press against the outer periphery of the insertion portion 22; when the locking device is in the locked state, the second shell 20 rotates relative to the first shell 10. During the rotation, the driving structure drives the sleeve 30 to press down, so that the movable buckle 40 disengages from the groove 31 and moves toward the outer periphery of the insertion portion 22 to press against the outer periphery of the insertion portion 22, thereby fixing the second shell 20 to the first shell 10.

[0038] The locking device can realize the opening and closing connection between the first shell 10 and the second shell 20. The connection between the two is firm, and the second shell 20 is not easy to escape from the first shell 10. The locking device has high structural reliability, simple assembly and low process cost.

[0039] In some embodiments, a limiting groove 221 is provided on the outer periphery of the insertion portion 22 for partially inserting the movable buckle 40 therein so that the locking device is in a locked state. The limiting groove 221 can be a whole annular groove structure, or the limiting groove 221 can be a plurality of concave groove structures, and the plurality of concave grooves are arranged at intervals along the outer periphery of the insertion portion 22.

[0041] When the locking device is in an unlocked state, the plug-in portion 211 is located in the slot portion 32; when the locking device is in a locked state, the plug-in portion 211 abuts against the flat portion 33 to drive the sleeve 30 to move downward. When the sleeve 30 moves downward, the movable buckle 40 can be driven to move toward the center of the accommodating portion 12, and then can be tightened to the outer periphery of the insertion portion 22.

[0042] Preferably, the number of the slot parts 32 can be two, and the two slot parts 32 are symmetrically arranged at the upper end of the housing 30. Correspondingly, the two plug parts 211 are also arranged accordingly. Of course, the number of the slot parts 32 and the plug parts 211 can also be other numbers, and their arrangement positions can also be adjusted according to actual needs, which is not specifically limited here.

[0043] In some embodiments, both sides of the slot portion 32 along the circumferential direction are inclined surfaces, and both sides of the plug portion 211 along the circumferential direction are inclined surfaces, so that when the second shell 20 rotates circumferentially, the plug portion 211 can smoothly enter and exit the slot portion 32.

[0044] In some embodiments, a first positioning groove 321 is defined in the slot portion 32 , a second positioning groove 331 is defined on the plane portion 33 , and a protrusion 212 matching with the first positioning groove 321 or the second positioning groove 331 is defined on the plug-in portion 211 .

[0045] When the locking device is in an unlocked state, the plug-in portion 211 cooperates with the slot portion 32, and the protrusion 212 is located in the first positioning groove 321. When the locking device is in a locked state, the plug-in portion 211 cooperates with the plane portion 33, and the protrusion 212 is located in the second positioning groove 321.
