[0009] In one embodiment, the upper pressure cover has an upper sliding groove on the side near the rotating rod, and the lower pressure cover has a lower sliding groove on the side near the rotating rod. The upper sliding groove, the lower sliding groove, and the middle sliding groove are connected to form a closed groove, and the reset member and the elastic limiting member are disposed in the closed groove.

[0010] In one embodiment, the number of closed slots is at least two, and each of the closed slots is symmetrically distributed relative to the rotation axis.

[0011] In one embodiment, the upper pressure cover forms an upper limit boss on the outer periphery of the upper sliding groove, the lower pressure cover forms a lower limit boss on the outer periphery of the lower sliding groove, and the opposite sides of the rotating rod form stepped grooves on the outer periphery of the middle sliding groove.

[0026] A rotating bracket is a mechanical structure design widely used in scenarios requiring precise control of rotation angles, clear feedback, and structural stability. For example, rotating brackets can be used to adjust the angle and height of a monitor, providing stable support and flexible rotation; they can be used in gimbals, tripods, etc., requiring precise control of rotation angles and clear feedback for photographers to quickly position themselves; and they can be used in vehicle mounts, requiring a stable rotating structure and clear positioning feedback. In existing technologies, some traditional rotating mechanisms lack clear feedback mechanisms, making it impossible for users to perceive the rotation angle, resulting in a poor user experience. Some rotating mechanisms are also complex in structure, high in manufacturing costs, and difficult to maintain; frequent rotation can lead to component wear and affect their lifespan.

[0027] refer to Figures 1-5 To address the aforementioned issues, this application provides a rotating bracket 10, comprising a base 20, a rotating rod 30, and a feedback component 40. A rotating shaft 21 protrudes from the base 20. The rotating rod 30 is sleeved on the rotating shaft 21 and can rotate relative to the rotating shaft 21. The rotating rod 30 is rotatably connected to the base 20. The outer peripheral wall 211 of the rotating shaft 21 forms multiple locking structures 212 along the circumferential direction. The feedback component 40 is fixed to the rotating rod 30 and movably abuts against the outer peripheral wall 211 of the rotating shaft 21. The feedback component 40 is located on the radial periphery of the rotating shaft 21. The feedback component 40 can engage or disengage from the locking structures 212 as the rotating rod 30 rotates relative to the base 20.

[0028] See Figure 2 and Figure 3 The rotating bracket 10 includes a base 20, a rotating rod 30, and a feedback component 40. The base 20 forms the mounting part of the rotating bracket 10, and a rotating shaft 21 structure protrudes from the base 20. The rotating rod 30 can rotate relative to the rotating shaft 21 of the base 20. Specifically, the rotating rod 30 is sleeved on the rotating shaft 21 and can rotate relative to the rotating shaft 21. In some embodiments, the base 20 can be set as a circular structure, with the rotating shaft 21 structure protruding at the center of the circular base 20. The outer peripheral wall 211 of the rotating shaft 21 forms multiple locking structures 212 along the circumferential direction. The locking structures 212 cooperate with the feedback component 40 to generate obvious tactile feedback of "locking in" and "unlocking out" during rotation. When the user rotates the rotating rod 30, they can clearly perceive the position of each locking point, thereby achieving precise positioning and control. The locking structures 212 are distributed circumferentially to form multiple fixed positioning points, allowing the rotating rod 30 to stop at a specific angle. In some embodiments, the feedback component 40 is fixed to the rotating rod 30 and movably abuts against the outer peripheral wall 211 of the rotating shaft 21. The feedback component 40 can engage or disengage from the locking structure 212 as the rotating rod 30 rotates relative to the base 20. When the user rotates the rotating rod 30, they can clearly perceive the position of each locking point, thus achieving precise positioning and control. The feedback component 40's ability to engage or disengage from the locking structure 212 allows the rotating rod 30 to stop at a specific angle, achieving step-by-step positioning. The user can fix the rotating rod 30 at a preset angle position, avoiding accidental displacement due to external force or vibration. In some embodiments, the locking structure 212 can be a locking groove, in which case the elastic limiting member 42 is a ball; the locking structure can also be a protruding structure, in which case the elastic limiting member 42 is a slider with a locking groove. The cooperation between the feedback component 40 and the locking structure 212 forms a mechanical locking mechanism, achieving positioning without additional electronic or hydraulic devices. This enables precise rotational feedback, step-by-step positioning, enhanced structural stability, and improved operational convenience.

[0029] In some embodiments, the locking structure 212 includes a locking groove. The feedback assembly 40 includes a reset member 41 and an elastic limiting member 42. The reset member 41 and the elastic limiting member 42 are disposed on the rotating rod 30. The elastic limiting member 42 is slidably connected between the reset member 41 and the outer peripheral wall 211 of the rotating shaft 21 along the radial direction of the rotating shaft 21. A spring can be used as the reset member 41. Specifically, one end of the spring is fixed inside the rotating rod 30, and the other end contacts the elastic limiting member 42. This structure is simple and low-cost, while enabling the elastic force of the feedback assembly 40 to be adjustable. In some embodiments, depending on actual needs, if the structure of the rotating bracket 10 needs to be smaller, an elastic sheet can be used as the reset member 41. An elastic metal sheet can be used as the reset member 41. One end of the elastic sheet is fixed inside the rotating rod 30, and the other end contacts the elastic limiting member 42. Compared with a spring, the elastic metal sheet has the advantages of compact structure and small space occupation. In some embodiments, a rubber block can be used as the reset element 41. The rubber block is fixed inside the rotating rod 30 and contacts the elastic limiting element 42. Rubber has good cushioning and shock absorption effects. The elastic limiting element 42 can be made of steel balls, ceramic balls, or plastic balls. Steel balls have better wear resistance and a longer service life. Ceramic balls have better corrosion resistance and are suitable for harsh environments. When plastic balls are used as the elastic limiting element 42, the cost of the rotating bracket 10 can be reduced, and their lighter weight can reduce the overall weight of the rotating bracket 10.

[0030] See Figure 2 and Figure 3 A central groove 51 is provided in the rotating rod 30 along the radial direction of the rotating shaft 21. An elastic limiting member 42 and a resetting member 41 are disposed in the central groove 51. Specifically, the central groove 51 can be a straight groove, with the elastic limiting member 42 and the resetting member 41 sliding linearly within the groove. This design is simple and easy to manufacture and install. In some embodiments, the central groove 51 can also be arc-shaped, with the elastic limiting member 42 and the resetting member 41 sliding arc-shaped within the groove, resulting in smoother sliding and reduced jamming. Alternatively, the central groove 51 can be divided into multiple segments, each corresponding to a locking structure 212. The elastic limiting member 42 and the resetting member 41 slide segmentally within the groove, providing clearer rotational feedback and achieving a step-by-step positioning function. When machining the central groove 51, milling can be used. A milling machine can be used to mill the central groove 51 radially along the rotating shaft 21 in the rotating rod 30, which has high machining accuracy. Alternatively, the central groove 51 can be formed directly in the central groove 51 during the injection molding process, which has high machining efficiency and can reduce manufacturing costs.

[0031] The feedback assembly 40 includes an upper cover 43 and a lower cover 44, which can be connected by threads. For example, threaded holes 442 are provided on the upper cover 43 and the lower cover 44, and screws are used to fix the upper cover 43 and the lower cover 44 to opposite sides of the rotating rod 30. This ensures a stable connection between the upper cover 43 and the lower cover 44 of the feedback assembly 40, and facilitates disassembly and maintenance. In some embodiments, the upper cover 43 and the lower cover 44 can also be connected by snap-fit ​​fasteners, which engage with opposite sides of the rotating rod 30. This allows for quick installation of the upper cover 43 and the lower cover 44 of the feedback assembly 40, enabling the installation and removal of the upper cover 43 and the lower cover 44 without tools. The upper pressure cover 43 and the lower pressure cover 44 are fitted onto the rotating shaft 21 and are respectively fixedly connected to opposite sides of the rotating rod 30. The upper pressure cover 43 and the lower pressure cover 44 restrict the reset member 41 and the elastic limiting member 42 within the rotating rod 30, so that the reset member 41 and the elastic limiting member 42 are stably restricted within the rotating rod 30. In some embodiments, the upper pressure cover 43 and the lower pressure cover 44 may have a planar structure. In some embodiments, the upper pressure cover 43 and the lower pressure cover 44 may have a boss structure on the side near the rotating rod 30. The boss engages with opposite sides of the rotating rod 30, which can increase the stability of the connection and reduce the risk of loosening and falling off.

[0032] The upper pressure cover 43 has an upper sliding groove 52 on the side near the rotating rod 30, and the lower pressure cover 44 has a lower sliding groove 53 on the side near the rotating rod 30. The upper sliding groove 52, the lower sliding groove 53, and the middle sliding groove 51 are connected to form a closed groove 50. The reset member 41 and the elastic limiting member 42 are disposed in the closed groove 50. The upper pressure cover 43 and the lower pressure cover 44 seal the closed groove 50, which can prevent dust and debris from entering. There are at least two closed grooves 50, and each closed groove 50 is symmetrically distributed relative to the rotating shaft 21. The upper sliding groove 52, the lower sliding groove 53, and the middle sliding groove 51 can all be straight lines, connected to form a straight closed groove 50. The reset member 41 and the elastic limiting member 42 slide linearly in the closed groove 50. In some embodiments, the upper slide groove 52, the lower slide groove 53, and the middle slide groove 51 are arc-shaped, connecting to form an arc-shaped closed groove 50. The reset member 41 and the elastic limiting member 42 slide arc-shaped within the closed groove 50, resulting in smoother sliding and reduced jamming. In some embodiments, the upper slide groove 52, the lower slide groove 53, and the middle slide groove 51 are divided into multiple segments, each corresponding to a locking structure 212. The reset member 41 and the elastic limiting member 42 slide segmentally within the closed groove 50, providing clearer rotational feedback and achieving step-by-step positioning. In some embodiments, a sealing ring can be provided at the opening of the closed groove 50, providing a good seal, preventing dust and debris from entering, and extending the service life of the rotating bracket 10. In some embodiments, glue can be used to seal the opening of the closed groove 50 to prevent dust and debris from entering, reducing the manufacturing cost of the rotating bracket 10. The closed groove 50 can be made of metal materials, such as aluminum alloy or stainless steel, which have the advantages of high strength and durability. High-strength plastic material can also be used for the closing groove 50. The plastic closing groove 50 is lightweight, which can reduce the overall weight of the rotating bracket 10. Alternatively, composite materials can be used to make the closing groove 50. Composite materials combine the advantages of metal and plastic, and have the effects of high strength, light weight, and corrosion resistance.

[0033] The upper pressure cover 43 forms an upper limit boss on the outer periphery of the upper sliding groove 52, and the lower pressure cover 44 forms a lower limit boss 441 on the outer periphery of the lower sliding groove 53. For example, the upper limit boss and the lower limit boss 441 are annular structures, forming around the outer periphery of the upper sliding groove 52 and the lower sliding groove 53 respectively. The structure is symmetrical, which can make the rotating bracket 10 uniformly stressed and securely installed. In some embodiments, the upper limit boss and the lower limit boss 441 are segmented structures, forming multiple boss segments around the outer periphery of the upper sliding groove 52 and the lower sliding groove 53 respectively, which can reduce material usage and reduce the weight of the rotating bracket 10. The upper limit boss and the lower limit boss 441 can be made of elastic material. Elastic material has a certain elastic deformation capacity, which can absorb vibration and impact, and improve the durability of the rotating bracket 10. When the rotating bracket 10 is used in automobiles, the elastic material can improve the buffering and shock absorption capacity of the rotating bracket 10. The opposite sides of the rotating rod 30 form stepped grooves 31 on the outer periphery of the central sliding groove 51. The upper limit boss and the lower limit boss 441 are both engaged in the stepped grooves 31. In some embodiments, the upper limit boss and the lower limit boss 441 are interference-fitted with the stepped grooves 31 to ensure the stability of the connection, so that the rotating bracket 10 is firmly connected and the risk of loosening and falling off is reduced.

[0034] See Figure 3 The rotating bracket 10 includes fasteners 60. The upper pressure cover 43 has a first through hole, the rotating rod 30 has a second through hole 32, and the lower pressure cover 44 has a threaded hole 442. The fasteners 60 pass through the first and second through holes 32 sequentially and are threaded into the threaded hole 442. The first through hole, second through hole 32, and threaded hole 442 are coaxially arranged to ensure that the fasteners 60 can pass smoothly and be threadedly connected. The structure is simple and easy to process and install. Multiple sets of first through holes, second through holes 32, and threaded holes 442 are respectively provided on the upper pressure cover 43, the rotating rod 30, and the lower pressure cover 44, and are connected by multiple sets of fasteners 60. For example, four sets of through holes and fasteners 60 can be provided, distributed in four directions on the upper pressure cover 43. The angle between each pair of adjacent fasteners 60 and the axis is 90 degrees to ensure even force distribution and make the rotating bracket 10 connection more stable. In some embodiments, a screw can be used as a fastener 60, passing sequentially through the first through hole of the upper pressure cover 43 and the second through hole 32 of the rotating rod 30, and threadedly connected to the threaded hole 442 of the lower pressure cover 44. In some embodiments, a bolt and nut can be used as fasteners 60, with the bolt passing sequentially through the first through hole of the upper pressure cover 43 and the second through hole 32 of the rotating rod 30, and threadedly connected to the threaded hole 442 of the lower pressure cover 44, and the nut fixed to the other end of the bolt.

[0035] The rotating bracket 10 also includes a top cover 70, which is fixed to the end of the rotating shaft 21. Specifically, an external thread can be opened at the end of the rotating shaft 21, and an internal thread can be opened inside the top cover 70. The top cover 70 is fixed to the end of the rotating shaft 21 through the threaded connection. The rotating rod 30, the upper pressure cover 43, and the lower pressure cover 44 are clamped between the top cover 70 and the base 20. The clamping force between the top cover 70 and the base 20 clamps the rotating rod 30, the upper pressure cover 43, and the lower pressure cover 44 in the middle to ensure the stability of the connection.

[0036] In some embodiments, the number and distribution of the locking structures 212 can be adjusted according to actual needs to determine the adjustable angle range of the rotating rod 30. By rationally designing the number and spacing of the locking structures 212, multi-angle adjustment functions can be achieved. Simultaneously, the design of the locking structures 212 can disperse the contact pressure between the feedback component 40 and the rotating shaft 21, reducing localized wear, extending the service life of the rotating shaft 21 and the feedback component 40, and improving the durability of the equipment. In some embodiments, multiple locking structures 212 are provided, with multiple locking slots on the rotating shaft 21 continuously distributed circumferentially to form a staggered pattern. The depth and width of each locking structure 212 are consistent, ensuring that the feedback component 40 can be evenly engaged and disengaged, resulting in uniform rotational feedback. Furthermore, the depth and width of each locking structure 212 can be adjusted as needed to achieve specific positioning functions.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
