[0025] Referring Figure 1-6 as shown, it is a preferred embodiment provided by the present utility model.

[0026] A 90° flip self-locking rotating shaft mechanism for a smart watch, comprising a rotating shaft member 1 and a locking member 2. The rotating shaft member 1 passes through the locking member 2. The locking member 2 has a locking flat surface 211, and the rotating shaft member 1 has a shaft convex portion 11. The shaft convex portion 11 is arranged in an arc-shaped protrusion outward. The rotating shaft member 1 is arranged to rotate under the action of a driving force. When the shaft convex portion 11 abuts against the locking flat surface 211, the locking member 2 is in an elastic deformation state, and the locking member 2 elastically deforms to lock the rotating shaft member 1 in the reverse direction. When the shaft convex portion 11 is misaligned with the locking flat surface 211, the rotating shaft member 1 is in a hovering state.

[0027] For the above-mentioned 90° flip self-locking rotating shaft mechanism for a smart watch, when the user flips the smart watch by 90°, the user applies a rotational force to cause the rotating shaft member 1 to be arranged to rotate. When the shaft convex portion 11 abuts against the locking flat surface 211, the shaft convex portion 11 causes the locking member 2 to be in an elastic deformation state, and the locking member 2 elastically deforms to lock the rotating shaft member 1 in the reverse direction, achieving a self-locking effect. When the shaft convex portion 11 is misaligned with the locking flat surface 211, the rotating shaft member 1 is in a hovering state, which is convenient for the use of the smart watch. In this way, through the interference fit between the rotating shaft member 1 and the locking member 2, the smart watch flip has a self-locking function, meeting the different usage requirements of users, improving the practicality of the smart watch, and facilitating the use of the smart watch.

[0028] The locking member 2 has two locking flat surfaces 211, and the two locking flat surfaces 211 are symmetrically arranged along the center; along the radial direction of the rotating shaft member 1, shaft convex portions 11 are respectively formed at both ends of the rotating shaft member 1; in the locked state, the two shaft convex portions 11 respectively abut against the two locking flat surfaces 211.

[0029] In this way, in the locked state, under the combined action of the two shaft convex portions 11 and the two locking flat surfaces 211, the locking effect of self-locking is enhanced, and the self-locking effect is improved.

[0030] The locking member 2 includes two locking plates, which are symmetrically arranged and elastically deformed under force. The locking plates have a locking flat surface 211 and a locking arc surface 212, which are butt-jointed. When in the hovering state, the shaft protrusion 11 is in contact with the locking arc surface 212.

[0031] In this way, under the cooperation of the shaft protrusion 11 and the locking arc surface 212, the hovering stability in the hovering state is improved, ensuring the use of the smart watch.

[0032] The locking member 2 includes a main locking part, the two ends of which are respectively connected to the two locking plates and are arranged as an integral unit; the main locking part has a main locking surface 213, and the main locking surface 213 is arranged in an arc shape along a direction away from the locking arc surface 212; when in the hovering state, the two axial protrusions 11 are respectively arranged in contact with one of their locking arc surfaces 212 and the main locking surface 213.

[0033] In this way, under the cooperation of the locking arc surface 212 and the main locking surface 213, the hovering stability in the hovering state is improved, ensuring the use of the smart watch.

[0034] The locking member 2 includes a plurality of locking blocks 21 , each of which is arranged in an overlapping manner. The rotating shaft member 1 is synchronously provided with each of the locking blocks 21 . The locking blocks 21 have locking flat surfaces 211 , and the shaft protrusions 11 are synchronously arranged in abutment with each of the locking flat surfaces 211 .

[0035] In this way, under the cooperation of each locking block 21, the axial protrusion 11 facilitates each locking block 21 to be transformed into an elastic deformation state, thereby facilitating the flipping and self-locking of the smart watch.

[0036] The self-locking shaft mechanism for 90° flipping of the smart watch includes a flip member 3, which is used for flipping at 90°. The flip member 3 is docked with the shaft member 1, and the flip member 3 is used for causing the shaft protrusion 11 to conflict with or be misaligned with the locking flat surface 211.

[0037] In this way, under the action of the flip member 3, it is convenient to apply the driving force, thereby facilitating the driving of the rotating shaft member 1, thereby realizing the flipping of the smart watch.

[0038] The flip member 3 includes a flip plate 31 and an axis fixing plate 32. The axis fixing plate 32 is passed through the rotating shaft member 1, and the axis fixing plate 32 is arranged parallel to the rotating shaft member 1 in the radial direction. The inner end of the flip plate 31 is connected to the axis fixing plate 32, and the outer end of the flip plate 31 is vertically extended in a direction perpendicular to the axis fixing plate 32. When self-locking, the flip plate 31 is used to flip 90°; in this way, under the action of the flip plate 31, it is easy to flip 90°, thereby facilitating the use of the self-locking function.

[0039] The 90° flip self-locking rotating shaft mechanism for a smart watch includes a rotating shaft housing, two rotating shaft members 1, and two locking members 2. The two rotating shaft members 1 and the two locking members 2 are arranged in a one-to-one correspondence and assembled, and the two rotating shaft members 1 and the two locking members 2 are respectively installed at both ends of the rotating shaft housing.

[0040] In this way, under the cooperation of the two rotating shaft members 1 and the two locking members 2, the flip of the smart watch is more stable, and self-locking is performed on both sides to improve the self-locking effect and the hovering stability.

[0041] A housing cavity is formed in the middle of the rotating shaft housing, and the outer end of the rotating shaft member 1 penetrates the rotating shaft housing and extends into the housing cavity; in this way, it is convenient for the assembly of the rotating shaft member 1 and the external structure, so as to facilitate the flip and hovering of the smart watch.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
