An embodiment of the present utility model provides a bracket 200 (refer to fig. 10) including a rotating shaft structure 100. Referring to fig. 1, the rotary shaft structure 100 includes a first connector 10 and a second connector 20, and the second connector 20 is stacked on the first connector 10. Referring to fig. 2 and 3, the first connector 10 specifically includes a fixing portion 11, an elastic connection portion 12, and a boss 13. The elastic connection 12 and the sleeve 13 are provided between the fixing portion 11 and the second connection member 20. Wherein, referring to fig. 4, the fixing portion 11 has a first surface 111 and a second surface 112 opposite in a first direction. The second connector 20 is specifically stacked on the first surface 111, and the second surface 112 is located on a side of the first surface 111 away from the second connector 20. One end of the elastic connection portion 12 is connected to the fixing portion 11, and the opposite end is connected to the boss 13. The boss 13 is formed with, for example, a shaft hole 131 (see fig. 8). The shaft core 30 is inserted into the shaft hole 131 of the shaft sleeve 13. The second connector 20 is connected to the shaft core 30 and is rotatably connected to the first connector 10 through the shaft core 30. Wherein, the shaft core 30 is fixedly connected with the shaft sleeve 13, and the second connecting piece 20 is rotationally connected with the shaft core 30; alternatively, the shaft core 30 may be rotatably connected to the shaft sleeve 13, and the second connecting member 20 may be fixedly connected to the shaft core 30. Wherein, the elastic connection portion 12 can be elastically deformed to open or close with respect to the fixing portion 11. The sleeve 13 is movable toward and away from the first surface 111 upon elastic deformation of the elastic connection 12. For example, the elastic connection 12 is switched from the movement state in fig. 3 to fig. 4 in that the sleeve 13 moves away from the first surface 111 in the first direction. Wherein the state of the elastic connection 12 in fig. 3 may be referred to as a closed state of the elastic connection 12, and the state of the elastic connection 20 in fig. 4 may be referred to as an open state of the elastic connection 12. The end of the second connecting member 20 remote from the elastic connecting portion 12 is rotatable about the sleeve 13 such that an angle is formed between the second connecting member 20 and the first surface 111.

When the rotating shaft structure 100 provided in the present embodiment is applied to the bracket 200, the second connecting piece 20 is stacked on the first surface 111 corresponding to the storage state of the bracket 200, and the second connecting piece 20 rotates relative to the first connecting piece 10 to form an included angle with the first surface 111 corresponding to the unfolding state of the bracket 200.

Fig. 1 and 3 show the state of the rotating shaft structure 100 when the bracket 200 is in the storage state, and fig. 2 and 4 show the state of the rotating shaft structure 100 when the bracket 200 is in the unfolding state.

The use principle of the spindle structure 100 provided in this embodiment is as follows: first, when the rotary shaft structure 100 is in the state shown in fig. 1, the elastic connection portion 12 and the sleeve 13 are sandwiched between the fixing portion 11 and the second connection member 20, and at this time, the elastic connection portion 12 is in the closed state. Since the shaft core 30 is inserted into the shaft sleeve 13, the elastic connection portion 12, the shaft sleeve 13 and the shaft core 30 are all hidden between the fixing portion 11 and the second connection member 20, so that dust is not easy to enter, and a longer service life of the rotating shaft structure 100 can be ensured. In addition, compared with the problem that two connecting pieces of the traditional rotating shaft structure are respectively located on two sides of the shaft core and occupy large areas, in the embodiment, the rotating shaft structure 100 is in a storage state, namely, the first connecting piece 10 and the second connecting piece 20 are stacked on the same side, so that the occupied area is smaller, and the structure is more compact.

When the second connecting piece 10 is rotated to form an included angle with the first surface 111, the elastic connecting portion 12 is close to one end of the shaft sleeve 13, and the shaft sleeve 13 can be away from the first surface 111 along with the movement of the second connecting piece 20, at this time, the elastic connecting portion 12 is elastically deformed to be in an open state, so that the displacement lifting of the second connecting piece 20 can be realized, and the large-angle unfolding of the second connecting piece 20 can be realized, so that the supporting effect can be realized. When the supporting function is not needed, the second connecting piece 20 is rotated to be close to the first surface 111 and finally stacked on the first surface 111, the elastic connecting portion 12 is restored to be elastically deformed to be switched to the closed state, in the process, one end of the elastic connecting portion 12 close to the shaft sleeve 13 and the shaft sleeve 13 moves close to the first surface 111 to be displaced, and compared with the open state, the height occupied by the elastic connecting portion 12 and the shaft sleeve 13 in the closed state is lower, and the elastic connecting portion and the shaft sleeve can be better stored.

The fixing portion 11 is provided with a plurality of fixing holes 113 (see fig. 7), and the first connector 10 can be connected to an external structure such as a support sheet, a mobile phone case, or the like through the plurality of fixing holes 113, for example, a fixing column can be provided on the external structure, and the fixing of the first connector 10 can be achieved by caulking the fixing column and the fixing holes 113. The plurality of fixing holes 113 are arranged in a staggered manner, that is, the plurality of fixing holes 113 are not in a straight line, so that the stability of the connection between the first connecting piece 10 and the external structure can be improved.

Similarly, the second connector 20 is provided with a plurality of connection holes 23 (see fig. 4), for example, and the second connector 20 can be connected to an external structure through the plurality of connection holes 23. The bracket 200 includes, for example, a support member 40 (refer to fig. 9 and 10) connected to the second connection member 20, the support member 40 may be connected to the second connection member 20 through the plurality of connection holes 23, for example, connection posts may be provided on a corresponding external structure (for example, the support member 40), and the second connection member 20 may be fixed by riveting the connection posts and the connection holes 23. Wherein the plurality of connecting holes 23 are arranged in a staggered manner, that is, the plurality of connecting holes 23 are not aligned, the stability of the connection between the second connecting member 20 and the external structure can be increased.

In some embodiments, referring to fig. 4, a receiving groove 21 is formed on a side of the second connection member 20 adjacent to the first surface 111, and the elastic connection portion 12 and the sleeve 13 may be received in the receiving groove 21 when the second connection member 20 is stacked on the first surface 111. So that the overall thickness of the spindle structure 100 is thinner in the stowed condition.

In some embodiments, referring to fig. 1 and 2, a boss 22 is formed at an end of the second connector 20 connected to the shaft core 30, the boss 22 can rotate with rotation of the second connector 20 relative to the first connector 10, and the boss 22 is supported between the first surface 111 and the shaft core 30 when an angle is formed between the second connector 20 and the first surface 111. Referring to the state shown in fig. 1, in the storage state of the rotating shaft structure 100, the protruding portion 22 may be separated from the first surface 111 or contact with the first surface 111, and when the second connecting member 20 is rotated, the protruding portion 22 gradually abuts against the first surface 111 and supports the shaft core 30 to move in a direction away from the first surface 111, and simultaneously drives the shaft sleeve 13 to move in a direction away from the first surface 111, so as to drive the elastic connecting portion 12 to elastically deform and expand. So that the boss 22 can serve as a tilting fulcrum when the hinge structure 100 is operated, so that the stand 200 can be easily switched to the unfolded state.

In some embodiments, as shown in fig. 5, the fixing portion 11 and the elastic connecting portion 13 may be formed integrally, for example, by integral injection molding, so that the connection between the fixing portion 11 and the elastic connecting portion 12 is more firm, and the processing steps are fewer. Or in some embodiments, as shown in fig. 6, the fixing portion 11 and the elastic connection portion 12 may be separately arranged, and may be formed separately during preparation, and then connected into a whole by welding, bolting or riveting, so that the processing difficulty is lower. The sleeve 13 may be integrally formed with the elastic connection portion 12, for example, by crimping one end of a metal sheet to form the sleeve 13.

In some embodiments, as in the structures shown in fig. 2 to 6, the elastic connection portion 12 is formed with a plurality of through holes 121. In one specific example, the plurality of through holes 121 extend through the elastic connection portion 12 in the first direction, but in other embodiments, the through holes 121 may extend through the elastic connection portion 12 in other directions. However, in other embodiments, the elastic connection portion 12 may be specifically configured as shown in fig. 7, and it may be understood that the number of through holes 121 on the elastic connection portion 12 is 0.

Fig. 8 is a schematic view of section A-A of fig. 7, wherein the elastic connection portion 12 further includes an elastic arm 122 and a connection portion 123, the connection portion 123 is connected to the fixing portion 11, and the elastic arm 122 is connected between the connection portion 123 and the sleeve 13. Referring to fig. 7, the elastic connection portion 12 has an elastic arm width L1 and an elastic stroke L2, and when the elastic arm width L1 is larger than the elastic stroke L2 as shown in fig. 7, the angle at which the elastic connection portion 12 can be opened is small. When the plurality of through holes 121 are provided, the plurality of through holes 121 allow the plurality of elastic arms 122 of the elastic connection portion 12 to travel at intervals, and the elastic arm width of each elastic arm 122 becomes smaller, so that the elastic deformability of the elastic connection portion 12 can be increased, and thus the expandable angle of the elastic connection portion 12 can be increased.

With continued reference to fig. 8, the resilient arm 122 has opposite first and second ends, the first end being connected to the connecting portion 123 and the second end being connected to the sleeve 13. In the storage state of the stand 200, the elastic connection portion 12 is in a closed state, a first included angle is formed between the elastic arm 122 and the first surface 111, and the second end is closer to the second surface 112 than the first end. As shown in fig. 8, the elastic arm 122 forms a first angle α1 with the first surface 111, and the angle α1 ranges from 0 ° to 10 °. Referring to the orientation shown in fig. 8, i.e., the right end of the elastic arm 122 is lower than the left end, a structure is formed to incline from the upper left to the lower right.

In the storage state of the stand 200, the elastic arm 122 is in a closed state, and the shaft hole 131 is at least partially located between the first surface 111 and the second surface 112. The notch or the opening may be provided at the corresponding position of the fixing portion 11, so that the sleeve 13 partially sinks between the first surface 111 and the second surface 112 in the closed state, so that the height occupied by the elastic connection portion 12 and the sleeve 13 on the side of the first surface 111 away from the second surface 112 in the closed state is smaller, and the overall structure of the rotating shaft structure 100 is thinner in the storage state of the bracket 200.

The inclination direction of the tangential plane 132 is opposite to the inclination direction of the elastic arm 122, i.e. the direction shown in fig. 8, the inclination direction of the elastic arm 122 is from top left to bottom right, the shaft sleeve 13 is curled upwards to form the shaft hole 131 in a direction away from the first surface 111, the tangential plane 132 is located at one side of the first surface 111 facing away from the second surface 112, and the inclination direction of the tangential plane 132 is from top right to bottom left. Wherein, be provided with the plane that corresponds with tangent plane 132 on the axle core 30, can realize damping rotation effect. The oblique direction of the tangential plane 132 and the elastic arm 122 is opposite, so that the elastic connection portion 12 can be closed and clamped in a self-locking manner in the storage state of the bracket 200, and cannot be opened at will.

The structure of the bracket 200 applied to the protective case 300 is shown in fig. 9 and 10. In some embodiments, the bracket 200 further includes a fixing member 50, where the fixing member 50 is connected to the first connector 10, specifically, the fixing portion 11, and the fixing member 50 may be fixed to the back plate 301 of the protective case 300. The supporting member 40 is connected to the second connecting member 20, and the supporting member 40 can form an included angle with the fixing member 50 or the back plate 301 along with the rotation of the second connecting member 20, so that the electronic device sleeved in the protective case 300 can be placed obliquely by supporting the supporting member 40 on a table top or the like, and is convenient for viewing. Of course, in some embodiments, the stand 200 may be bonded to the back of the electronic device by adhesion, and the embodiment is not limited to the above example.
