【Detailed ways】

Please refer to FIG. 1 to FIG. 3 . FIG. 1 is a schematic structural view of an embodiment of a rotating mechanism for rotating an angle according to the present application. FIG. 2 is a schematic diagram of a disassembled structure of an embodiment of a rotating mechanism for angle rotation of the present application, and FIG. 1 is a schematic cross-sectional structure diagram of a rotating mechanism of a fixed angle rotation along an AA axis.

The rotating structure in the present embodiment includes a rotating shaft 11, at least one convex member 12, at least one groove member 13, and a rotating member 14.

At least one protruding member 12 is sleeved on the rotating shaft 11, and the protruding member 12 includes a protrusion 121.

The protruding member 12 may have any shape, for example, may be a circular ring, and the inner diameter of the circular inner ring is the same as the diameter of the rotating shaft 11, and is disposed on the rotating shaft 11 through the inner circumference; of course, it can also be sleeved. Any other shape on the rotating shaft 11, such as a foreign inner circle or the like. The number of the protruding members 12 may be one, and may be disposed on one side of the rotating shaft 11; or a plurality of the protruding members 12 may be provided at a plurality of positions corresponding to the rotating shaft 11 corresponding to the groove member 13, and may be specifically set according to requirements.

At least one groove member 13 is sleeved on the rotating shaft 11, and is disposed corresponding to the protruding member 12. The groove member 13 is evenly spaced apart in the circumferential direction of the rotating shaft 11 with a plurality of grooves 131 matching the protrusions 121.

The shape of the groove member 13 is not limited. The position of the groove member 13 is located on one side of the convex member 12, and the groove 131 is disposed opposite to the protrusion 121. The groove 131 may be a through groove or a non-through groove, and the specific shape satisfies the matching with the protrusion 121. For example, when the groove member 131 and the protruding member 121 are relatively displaced in the circumferential direction of the rotating shaft 11, the protrusion may be raised. 121 can slide out from the groove 131 and slide into the other groove 131. In an application scenario, the protrusion 121 is a diagonal trapezoidal table with a bottom area larger than the top area, and the groove 131 can be a rectangular groove. . The specific number of the grooves 131 can then be set according to the angular requirement of the fixed angle rotation. For example, when a fixed angle rotation of 15° is required, twenty four grooves can be evenly spaced along the circumferential direction of the rotating shaft 11.

The end portion of the rotating member 14 includes an elastic rotating arm 141 in the axial direction of the rotating shaft, and the rotating member 14 is sleeved on the rotating shaft 11 via the elastic rotating arm 141, and is further sleeved on the protruding member 12 and/or the groove member 13 Near the side of the end of the shaft 11.

Wherein, when the rotating member 14 is not rotated, the protrusion 121 is embedded in a groove 131, and when the rotating member 14 is axially rotated about the rotating shaft 11, under the pressing of the groove member 13 and/or the protruding member 12, The elastic rotating arm 141 is deformed outward in the axial direction of the rotating shaft 11, so that the projection slides from one groove 131 to the other groove 131 under the rotation of the rotating member 14.

The rotating member 14 is a member that can rotate at a fixed angle around the rotating shaft 11 in the rotating mechanism, and the rotating member 14 is fixedly or non-fixedly connected with the rotating shaft 11. A circular hole may be formed in the elastic rotating arm 141, and the rotating member 14 is sleeved on the rotating shaft 11 through the circular hole. When the elastic rotating arm 141 is sleeved on the side of the protruding member 12 and/or the groove member 13 near the end of the rotating shaft 11, the elastic rotating arm 141 is fixedly connected with the protruding member 12 and/or the groove member 13 at Together, or directly on the rotating shaft when the rotating member 14 and the rotating shaft 11 are non-fixedly connected, such that the rotating member is located on the side of the elastic rotating arm 141 when the rotating member 14 is axially rotated about the rotating shaft 11 The 12 and/or groove members 13 rotate with the rotating member 14. It should be noted that the protruding member 12 and/or the groove member 13 away from the elastic rotating arm 141 can be disposed according to the fixing manner of the protruding member 12, and can revolve with the protruding member 12 when the rotating member 14 rotates. The relative displacement of 11 weeks can be used, and is not limited here. In one application scenario, the resilient rotating arm 141 of the rotating member 14 is disposed on the side of the raised member 12 near the end of the rotating shaft 11, and the two are detachably or non-detachably coupled together, and the groove member 13 is fixed to the outside. In the component, when the rotating member 14 rotates, the relative displacement between the protruding member 12 and the groove member 13 occurs, and the rotating member 14 can be rotated at a fixed angle.

The material of the elastic rotating arm 141 is an elastic material, which can be deformed by an external force and returned to the original shape after the external force is released, and may be, for example, silicone rubber or rubber.

When the rotating mechanism in the present embodiment is assembled, the rotating shaft 11 may be sequentially sleeved according to the positional relationship between the respective components, and then the rotating shaft 11 is limited by riveting or the like to the components sleeved at both ends of the rotating shaft 11. .

The rotating mechanism that rotates at an angle in the present embodiment includes: a rotating shaft 11, at least one convex member 12, at least one groove member 13, and a rotating member 14; wherein, when the rotating member 14 is not rotated, the convex portion of the convex member 12 121 is embedded in a recess 131 of the recess member 13, and when the rotary member 14 is rotated about the rotary shaft 11, the elastic rotary arm 141 of the rotary member 14 is pressed by the recess member 13 and/or the projection member 12. The axial direction of the rotary shaft 11 is deformed outward, so that the projection 121 slides from one groove 131a to the other groove 131b under the rotation of the rotary member 14. In the above manner, the elastic rotating arm 141 is deformed outward when rotating, so that the protrusion 121 slides from one groove 131 to the other groove 131 to achieve a fixed angle rotation, and the entire rotating mechanism can be reduced without using a compression spring. At the same time, it is not necessary to reserve the stroke of the compression spring in the axial direction. Therefore, when the rotary member 14 is axially rotated about the rotary shaft 11, the amplitude of the sway of the rotating mechanism can be reduced, and the stability of the mechanism can be improved.

Wherein, the number of the elastic rotating arms 141 can be set according to requirements. In an embodiment, the rotating component 14 includes two elastic rotating arms 141, and the rotating component 14 is sleeved on the protruding component 12 by two elastic rotating arms 141 and/or The groove member 13 is adjacent to the side of the end of the rotating shaft 11.

In the present embodiment, the rotating member 14 includes two elastic rotating arms 141, so that the rotating member 14 can be more stably sleeved on the rotating shaft 11, which is advantageous for improving the stability of the structure.

In one embodiment, the raised member 12 is a washer that includes a protrusion 121.

In one embodiment, the rotating member 14 is sleeved on the side of the protruding member 12 near the end of the rotating shaft 11 by the elastic rotating arm 141, and the elastic rotating arm 141 is disposed first on the side close to the protruding member 12. a boss 142; a side of the protruding member 12 adjacent to the elastic rotating arm 141 is provided with a first recess 122 matching the first boss 142; wherein, when the first boss 142 is received in the first recess 122, When the rotating member 14 is rotated about the rotating shaft 11, the relative displacement of the rotating shaft 11 in the circumferential direction does not occur between the elastic rotating arm 141 and the protruding member 12.

The shape of the first boss 142 and the first recess 122 is not limited. For example, the first boss 142 may be a cylindrical boss, and the first recess 122 is a circular shape that penetrates or does not penetrate the protruding member 12. The hole, when assembling the rotating mechanism, accommodates the first boss 142 in the first recess 122, thereby connecting the elastic rotating arm 141 and the protruding member 12.

The number of the first bosses 142 and the first recessed holes 122 is not limited. In one application scenario, the number of both is four and is evenly distributed along the circumferential direction of the rotating shaft 11.

With the present embodiment, the elastic rotating arm 141 and the protruding member 12 can be detachably coupled together such that when the rotating member 14 rotates, no relative displacement occurs between the two, further causing the protruding member 12 and the groove Relative displacement occurs between the components 13, thereby effecting a fixed angular rotation of the rotating component 14.

Wherein, in one embodiment, the groove member 13 is a toothed washer, and the groove 131 is a rectangular groove uniformly distributed along the outer edge of the toothed washer.

Similarly, by designing the groove member 13 as a gasket, the rotating mechanism can be made lighter without affecting its functionality, especially when used in a portable device, while at the same time reducing the cost of the rotating mechanism to a certain extent.

In one embodiment, the rotating mechanism further includes: a rotating bracket 15 that is sleeved on the rotating shaft 11 and fixed to an end of the groove member 13 away from the protruding member 12.

In one application scenario, the swivel bracket 15 can be the same component as the recess member 13, having both the function of the recess member 13 and the function of the swivel bracket 15.

In this embodiment, the rotating bracket 15 can be sleeved on the rotating shaft 11 through a circular hole at one end of the rotating bracket 15 , and the other end can be fixedly disposed at a certain position according to requirements. Since the rotating bracket 15 is fixed, the groove member 13 is also fixed. Thereby, it is possible to facilitate the rotation of the rotating member 14 about the rotating shaft 11; the rotating bracket 15 can also be connected to the other member at the other end, so that the rotating member 14 and the other member can be rotated at a fixed angle around the rotating shaft 11.

Wherein, when the second boss 151 is received in the second recess 132, when the rotating member 14 rotates around the rotating shaft 11, the relative displacement of the rotating shaft 11 in the circumferential direction does not occur between the rotating bracket 15 and the groove member 13.

In the present embodiment, the second boss 151 and the second recess 132 are similar to the shape and arrangement of the first boss 142 and the first recess 122 in the foregoing embodiment. For details, refer to the above embodiment. I won't go into details here.

Wherein, in one embodiment, the rotating member 14 includes two elastic rotating arms 141, and the number of the protruding members 12 and the groove members 13 are two; the two groove members 13 are symmetrically disposed on both sides of the rotating bracket 15 The rotating member 14 is sleeved on the side of the two convex members 12 near the end of the rotating shaft 11 by the two elastic rotating arms 141.

Wherein, when the rotating member 14 is not rotated, the two protrusions 121 are respectively embedded in the two grooves 131.
