[0002] Rotation functionality is widely used in modern electronic devices, mechanical devices, and everyday items, such as monitor stands, mobile phone stands, and robotic arms. Existing rotation mechanisms typically employ several fixing principles to achieve angle adjustment and locking functions, such as: screw fixing, where positioning holes are provided on the rotation mechanism and the bracket, and screws are used to fix the two together; or, locking fixing, where a clamping mechanism such as a locking band or clamping rod is used to fix the rotation mechanism and the bracket; or, damping connection, where a damper is placed between the rotation mechanism and the bracket, and the frictional damping provided by the damper achieves the fixation of the rotation mechanism and the bracket.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Please refer to Figures 1-7 One embodiment of this utility model provides a bracket rotation mechanism, including a base 1, a support member 2, and an elastic positioning component 3;

[0046] The base 1 has a boss 11, and the top of the boss 11 is provided with a receiving groove 12; the receiving groove 12 is provided with a first connecting shaft 13, and the bottom of the receiving groove 12 is provided with a mounting groove 14.

[0047] The connecting end 21 of the support member 2 is inserted into the receiving groove 12, and the connecting end 21 is hinged to the protrusion 11 through the first connecting shaft 13;

[0048] The elastic positioning component 3 is disposed in the mounting groove 14. The free end of the elastic positioning component 3 is hinged to the connecting end 21. The elastic positioning component 3 locks the rotated support member 2 in a stowed or unfolded state.

[0049] Understandably, in this embodiment, the connecting end 21 of the support member 2 is inserted into the receiving groove 12 and is hinged to the protrusion 11 through the first connecting shaft 13. The support member 2 is hinged to the base 1, and the support member 2 rotates around the first connecting shaft 13, thereby realizing the switching between the storage and unfolded states. The support member 2 can be flexibly adjusted between the storage state and the unfolded state.

[0050] The elastic locking module can lock the support member in a retracted or extended state using elastic force, ensuring that the bracket maintains a stable angle during use. For example, in the retracted state, when the support member 2 rotates to the retracted position, the elastic force of the elastic positioning component 3 acts on the support member 2, keeping it stable and close to the base 1, reducing the space occupied by the bracket in the retracted state; or, when the bracket needs to be used, an external force is applied to overcome the resistance of the elastic positioning component 3, causing the support member 2 to rotate around the first connecting shaft 13 to the extended position, and the elastic positioning component 3 again locks the support member 2 in the extended state using elastic force, ensuring that the bracket remains stable during use.

[0051] Furthermore, the elastic locking module can absorb some of the vibration energy, reducing the impact of vibration on the support structure.

[0052] Please refer to Figure 2 In one embodiment of the present invention, the bottom of the receiving groove 12 is an inclined surface, and the inclined surface gradually moves away from the base 1 in the vertical direction. The elastic positioning component 3 is disposed in the middle of the inclined surface through the mounting groove 14. The bottom of the receiving groove 12 is provided with a first positioning part 15 and a second positioning part 16. The first positioning part 15 is located at the lower part of the inclined surface, and the second positioning part 16 is located at the higher part of the inclined surface.

[0053] The support member 2 is provided with a first abutting part 22 and abutting part 23, and the first abutting part 22 and the second abutting part 23 are respectively located on both sides of the connecting end 21;

[0054] The first positioning part 15 is located on the rotation path of the first abutting part 22 and is used to interfere with the positioning of the first abutting part 22 so that the support member 2 is positioned in the storage state.

[0055] The second positioning part 16 is located on the rotation path of the second abutment part 23 and is used to interfere with the positioning of the second abutment part 23 so that the support member 2 is positioned in the unfolded state.

[0056] Understandably, in this embodiment, the bottom of the receiving groove 12 is designed as an inclined surface. The inclined surface gradually moves away from the base 1 in the vertical direction, forming an inclined support surface. The bottom of the inclined surface is also provided with a first positioning part 15 and a second positioning part 16, which are located at the low and high points of the inclined surface, respectively. The low point of the inclined surface refers to the starting side of the inclined surface, where the relative distance between the inclined surface and the base 1 is the shortest; the high point of the inclined surface refers to the ending side of the inclined surface, where the relative distance between the inclined surface and the base 1 is the farthest.

[0057] By using the inclined structure and the first and second positioning parts 16, the support member 2 is accurately positioned in the folded and unfolded states. The first positioning part 15 is located at the lower part of the inclined surface. When the support member 2 is rotated into place, the first abutting part 22 is blocked by the first positioning part 15. The interference between the first positioning part 15 and the first abutting part 22 restricts the further rotation of the support member 2, ensuring the stability of the support member 2 when folded.

[0058] The second positioning part 16 is located at the high point of the inclined plane. When the support member 2 is rotated to the unfolded position, the second abutting part 23 and the second positioning part 16 interfere with each other. The cooperation between the second positioning part 16 and the second abutting part 23 ensures the stability of the support member 2 in the unfolded state, so that the support member 2 can be firmly fixed in the unfolded state.

[0059] Therefore, this implementation enables the support member 2 to flexibly switch between the stowed and unfolded states, while the cooperation of the inclined structure and the positioning part ensures stability and reliability in both states.

[0060] Please refer to Figures 4-5 In one embodiment of the present invention, the support member 2 has a bent section 24, and the support end is located at the end of the bent section 24, so that the support member 2 is close to the base 1 when it is in the storage state.

[0061] Understandably, the design of the bending section 24 in this embodiment allows the support member 2 to fit tightly against the base 1 when stored, greatly reducing the overall thickness and space occupation of the bracket in the stored state. In the stored state, the center of gravity of the support member 2 is closer to the base 1, reducing swaying or loosening caused by external forces, improving the stability of the bracket in the stored state, and preventing the support member 2 from being accidentally unfolded due to accidental collisions or vibrations, thereby enhancing the safety of use.

[0062] Please refer to Figure 1 , Figure 4 and Figure 5 In one embodiment of the present invention, through holes are provided on both sides of the protrusion 11, and the first connecting shaft 13 includes a mounting bolt 131 and a mounting nut 132.

[0063] The mounting bolt 131 is disposed in a through hole on one side of the boss 11 and extends through to a through hole on the other side. A limiting block 133 is provided at the end of the mounting bolt 131. The limiting block 133 is fixed to the through hole to fix the mounting bolt 131 to the boss 11. The limiting block 133 is used to limit and fix the mounting bolt 131 and prevent the mounting bolt 131 from rotating with the support 2 due to friction when the support 2 rotates.

[0064] The mounting nut 132 is disposed in the through hole on the other side of the boss 11, and the mounting nut 132 is fixedly connected to the mounting bolt 131 by means of a washer.

[0065] Understandably, the connection method using mounting bolts 131 and mounting nuts 132 in this embodiment can provide high-strength fixation, ensure the connection stability between the support member 2 and the base 1, facilitate users or maintenance personnel to maintain, replace or adjust the support member 2, improve the convenience of use and maintenance, and the gasket can evenly distribute the pressure of the nut on the connection part, avoiding structural deformation or damage to the base 1 due to excessive local pressure.

[0066] Please refer to Figure 1 , Figure 5 and Figure 7 In one embodiment of the present invention, the elastic positioning component 3 includes a connecting card 31 and an elastic element 32;

[0067] A second connecting shaft 25 is provided on the outer side of the connecting end 21, and the connecting card 31 is hinged to the connecting end 21 through the second connecting shaft 25;

[0068] The elastic element 32 is disposed in the mounting groove 14, the elastic element 32 elastically abuts against the connecting card 31, and the elastic element 32 is in a compressed state when switching between the stored state and the unfolded state.

[0069] Understandably, in this embodiment, when the support member 2 switches from the retracted state to the unfolded state (or vice versa), the elastic member 32 is always in a compressed state, so that the elastic member 32 can provide a continuous elastic force for: in the retracted state, pressing the support member 2 tightly with the base 1 by the elastic force to reduce shaking; or in the unfolded state, the elastic force of the elastic member 32 helps the support member 2 to remain stable and prevent angular displacement caused by external force or vibration.

[0070] Furthermore, the connecting card 31 is hinged to the connecting end 21 of the support member 2 via the second connecting shaft 25, so that the connecting card 31 can rotate flexibly under the action of the elastic member 32, thereby realizing the angle adjustment of the support member 2.

[0071] Please refer to Figures 6-7 In one embodiment of the present invention, a connecting slot is provided on the outer side of the connecting end 21, and the connecting card 31 is snapped into the connecting slot;

[0072] The second connecting shaft 25 is disposed on the other side of the connecting end 21 opposite to the support member 2, and the second connecting shaft 25 is arranged parallel to the first connecting shaft 13.

[0073] The elastic element 32 is a helical spring, a gas spring, or a hydraulic spring.

[0074] Understandably, in this embodiment, the hinged design of the second connecting shaft 25 and the connecting card 31 allows the connecting card 31 to rotate freely under the action of the elastic member 32, thereby realizing a smooth switch between the support member 2 in the storage and unfolded states. At the same time, the elastic member 32 can effectively fix the support member 2 in the storage or unfolded state.

[0075] Please refer to Figures 1-7 In one embodiment of the present invention, the support member 2 is provided with weight reduction holes 26 on both sides, and the weight reduction holes 26 are weight reduction hollow holes or weight reduction blind holes.

[0076] Understandably, in this embodiment, weight-reducing hollow holes or weight-reducing blind holes are provided on both sides of the support member 2, which can achieve lightweight design without reducing structural strength, while optimizing the processing technology and improving material utilization.

[0077] In one embodiment of the present invention, a connecting hole is provided on one side of the supporting end of the support member 2, and a sleeve 27 is provided on the other side of the supporting end; the sleeve 27 is coaxial with the connecting hole;

[0078] And / or, the base 1 is provided with a fixing hole 28 on its side, and a fastener is provided in the fixing hole 28 for installing the base 1 to a predetermined installation position.

[0079] Understandably, when multiple support rotation mechanisms are set up simultaneously, the sleeve 27 and connecting hole provided at the support end in this embodiment can be used to connect the multiple support rotation mechanisms in series, thereby achieving synchronous control of the rotation of the multiple support rotation mechanisms.
