Description
Technical Field
[0001] This utility model belongs to the technical field of gimbal balance adjustment mechanism, specifically relating to a gimbal balance adjustment mechanism with fine adjustment function. Background Technology
[0002] Gimbals are commonly used in photography and videography auxiliary equipment. The gimbal support structure has a gimbal balance adjustment mechanism, which is used to adjust the balance of the gimbal. Specifically, after the camera or video camera is mounted on the gimbal support structure, the gimbal balance adjustment mechanism is needed to balance the weight of the camera, video camera, and other equipment. The most perfect balance is to just balance the weight of the load at every angle of pitch, thus providing a better foundation for the photographer's artistic creation.
[0003] In the prior art, the gimbal balancing mechanism generally has a main shaft, multiple torque discs mounted on the main shaft, and an adjustment knob. The adjustment knob controls the hook structure to lock onto the torque discs, so that the outer circumference of the torque disc cannot rotate, while the inner circumference continues to rotate with the main shaft. This causes the torque disc to generate torque force, which is fed back into the balancing operation to counteract the weight of the camera and camera, so that the whole can maintain balance.
[0004] The adjustment knobs in the prior art are generally coarse adjustment knobs, which cannot obtain very small adjustment torque. Therefore, when a small torque is required to achieve fine adjustment function, it is difficult to meet the requirements. Based on this, this application has further designed and improved the existing gimbal balance adjustment mechanism. Utility Model Content
[0005] To address the shortcomings of the existing technology, this utility model provides a gimbal balance adjustment mechanism with fine-tuning function. In addition to the existing adjustment knob, a fine-tuning knob is set up to control the corresponding fine-tuning torque disc, thereby obtaining smaller torque feedback and making up for the inability of existing products to achieve fine-tuning function.
[0006] The present invention is solved by the following technical solution.
[0007] A gimbal balancing adjustment mechanism with fine-tuning function includes a main body, a main shaft, and several synchronously rotating torque discs on the main shaft. The main shaft also includes several limiting members that can engage with corresponding torque discs to restrict the outer rotation of those discs. The main body has a coarse-adjustment knob that controls whether the corresponding limiting member engages with or disengages from the corresponding torque disc. The main body also has a fine-adjustment knob that controls whether the corresponding limiting member engages with or disengages from the corresponding torque disc. The torque of the torque disc matched with the fine-adjustment knob is less than the torque of the torque disc matched with the coarse-adjustment knob.
[0008] In the gimbal balancing mechanism of this application, in addition to the existing products which only have one coarse adjustment knob, a fine adjustment knob is additionally set. Furthermore, the torque of the torque disc corresponding to the fine adjustment knob is less than that of the other torque discs. Therefore, when adjusting, the fine adjustment knob can obtain a smaller torque force, thus enabling fine adjustment.
[0009] In a preferred embodiment, if the torque of the torque disc matching the coarse adjustment knob is N, then the torque of the torque disc matching the fine adjustment knob is 1 / 4N to 1 / 2N.
[0010] In a preferred embodiment, the number of torque discs matching the fine-tuning knob is 2 to 4.
[0011] In a preferred embodiment, the torque disc is a rubber disc. When the outer ring of the rubber disc is restricted from rotating, its inner ring will rotate synchronously with the main shaft. At the same time, the rubber layer between the outer ring and the inner ring will be stretched, generating torque force.
[0012] In a preferred embodiment, the limiting member is a hook located on the side of the torque disc, which is rotatably mounted on the assembly rod. One end of the hook is a snap-in end that can snap into a slot on the torque disc to limit the torque disc. The other end of the hook is a lifting section. When a force is applied to the lifting section, the hook can rotate around the assembly rod and the snap-in end can be disengaged from the slot. An elastic member is also provided, whose elastic force acts on the hook to make the snap-in end abut against the torque disc.
[0013] In a preferred embodiment, the main body is provided with at least one fine-tuning rod at a position corresponding to the fine-tuning knob. The fine-tuning knob, during rotation, drives the fine-tuning rod to move. When the fine-tuning rod moves, it acts on the lifting section to unlock the corresponding hook. In the default state, almost all the locking ends of the limiting components are pressed against the corresponding torque disc by the elastic force of the elastic element and locked into the slot. At this time, the torque is very large. The coarse-tuning knob and / or the fine-tuning knob can be used to control the movement of the corresponding coarse-tuning rod and / or fine-tuning rod to unlock the corresponding limiting component, reduce the torque, and then adjust.
[0014] In a preferred embodiment, the inner surface of the fine-tuning knob is provided with a fine-tuning boss and a corresponding fine-tuning ramp. When the fine-tuning knob is rotated, the corresponding fine-tuning push rod can be pushed out through the fine-tuning ramp and the fine-tuning boss, thereby unlocking the corresponding torque disc.
[0015] In a preferred embodiment, an angle limiting rod is provided on the main body at a position corresponding to the fine-tuning knob, and a sliding groove is provided on the fine-tuning knob. After assembly, the angle limiting rod is placed in the sliding groove to limit the rotation angle of the fine-tuning knob and prevent excessive rotation.
[0016] In a preferred embodiment, the torque discs matching the fine-tuning knob have a torque of 1 / 3N, and there are two discs, corresponding to two fine-tuning levers. In this structure, rotating the fine-tuning knob activates one corresponding fine-tuning lever while the other does not, meaning only one corresponding torque disc generates torque, thus obtaining 1 / 3N of torque. Continuing to rotate the knob, after both corresponding torque discs are deactivated, a torque of 2 / 3N can be obtained, achieving fine-tuning of the corresponding gear.
[0017] In a preferred embodiment, the elastic element is fixed to the inner frame in the main body, and the elastic element is provided with a plurality of spring pieces, which press against the limiting element to provide elastic force.
[0018] Compared with the prior art, the present invention has the following advantages: it provides a gimbal balance adjustment mechanism with fine adjustment function. On the basis of the existing adjustment knob, a fine adjustment knob is set up to control the corresponding fine adjustment torque disc, thereby obtaining smaller torque feedback and making up for the inability of existing products to achieve fine adjustment function.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0032] In the following embodiments, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0033] In the description of this utility model, it should be understood that the terms such as center, longitudinal, transverse, length, width, thickness, upper, lower, front, back, left, right, vertical, horizontal, top, bottom, inner, outer, clockwise, and counterclockwise, indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description; therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features shown. In the description of this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0034] See Figures 1 to 12 This utility model relates to a gimbal balancing adjustment mechanism with fine-tuning function, comprising a main body 1, a main shaft 5, and several synchronously rotating torque discs 4 on the main shaft 5. The main shaft 5 also includes several limiting members 62, which can be engaged with corresponding torque discs 4 to restrict the rotation of their outer rings 42. The main body 1 is provided with a coarse adjustment knob 2, which can control the corresponding limiting member 62 to engage or disengage from the corresponding torque disc 4. The main body 1 is also provided with a fine adjustment knob 3, which can control the corresponding limiting member 62 to engage or disengage from the corresponding torque disc 4. The torque of the torque disc 4 matched with the fine adjustment knob 3 is less than the torque of the torque disc matched with the coarse adjustment knob 2.
[0035] As can be seen from the accompanying drawings, in this application, the limiting member 62 is a hook located on the side of the torque disc 4. The hook is rotatably mounted on the assembly rod 6. One end of the hook is a snap-in end 621, which can snap into the slot 41 on the torque disc 4 to limit the torque disc 4. The other end of the hook is a lifting section 622. When a force is applied to the lifting section 622, the hook can rotate around the assembly rod 6 and the snap-in end 621 can be disengaged from the slot 41. An elastic member 63 is also provided. The elastic force of the elastic member 63 acts on the hook to make the snap-in end 621 abut against the torque disc 4.
[0036] Furthermore, in this application, the main body 1 is provided with at least one fine-adjustment rod 34 at the position corresponding to the fine-adjustment knob 3. During rotation, the fine-adjustment knob 3 can drive the fine-adjustment rod 34 to move. When the fine-adjustment rod 34 moves, it acts on the lifting section 622 to unlock the corresponding hook. In the default state, almost all the retaining members 62's locking ends 621 are pressed against the corresponding torque disc 4 by the elastic force of the elastic member 63 and locked into the slot 41. At this time, the torque is very large. The coarse adjustment knob 2 and / or the fine adjustment knob 3 can be used to control the movement of the corresponding coarse adjustment rod 24 and / or the fine adjustment rod 34 to unlock the corresponding retaining member 62, reduce the torque, and then adjust. The inner surface of the fine adjustment knob 3 is provided with a fine-adjustment boss 35 and a corresponding fine-adjustment ramp 351. When the fine adjustment knob 3 rotates, the fine adjustment ramp 351 and the fine adjustment boss 35 can push out the corresponding fine-adjustment rod 34, thereby unlocking the corresponding torque disc 4.
[0037] In this application, the elastic element 63 is fixed on the inner frame 61 in the main body 1. The elastic element 63 is provided with a plurality of spring pieces 631, which press against the limiting element 62 to provide elastic force.
[0038] Furthermore, in this application, the main body 1 is provided with an angle limiting rod 381 at the position corresponding to the fine-tuning knob 3, and the fine-tuning knob 3 is provided with a sliding groove 38. After assembly, the angle limiting rod 381 is placed in the sliding groove 38 to limit the rotation angle of the fine-tuning knob 3 and avoid excessive rotation.
[0039] In this application, the torque disc 4 is a rubber disc. When the outer ring 42 of the rubber disc is restricted from rotating, its inner ring 44 will rotate synchronously with the main shaft 5. At the same time, the rubber layer 43 between the outer ring 42 and the inner ring 44 will be stretched, generating torque force. In the specific structure, the inner ring 44 is provided with an inner ring groove 441, and the main shaft 5 is provided with a protrusion 54. After assembly, the inner ring groove 441 is engaged with the protrusion 54 to achieve synchronous rotation.
[0040] Furthermore, in this application, if the torque of the torque disc 4 matching the coarse adjustment knob 2 is N, then the torque of the torque disc 4 matching the fine adjustment knob 3 is 1 / 4N to 1 / 2N. Correspondingly, the number of torque discs 4 matching the fine adjustment knob 3 is 2 to 4. In the preferred embodiment shown in the accompanying drawings, the torque of the torque discs 4 matching the fine adjustment knob 3 is 1 / 3N, and there are two discs, corresponding to two fine adjustment levers 34. In this structure, rotating the fine adjustment knob 3 activates one corresponding fine adjustment lever 34, while the other does not, meaning only one corresponding torque disc 4 generates torque, obtaining 1 / 3N of torque. Continuing to rotate the fine adjustment knob 3, after both corresponding torque discs 4 are restricted, 2 / 3N of torque can be obtained, achieving fine adjustment of the corresponding gear.
[0041] As can be seen from the attached drawings, the main body 1 has a coarse adjustment knob mounting position 12 and a fine adjustment knob mounting position 13. The coarse adjustment knob mounting position 12 has a row of coarse adjustment holes 121 for mounting the coarse adjustment push rod 24, and correspondingly, the fine adjustment knob mounting position 13 has two fine adjustment holes 131 for mounting the fine adjustment push rod 34. The main body 1 has an assembly structure for mounting the internal structure, which can be integrally formed.
[0042] The coarse adjustment knob 2 in this application has multiple coarse adjustment bosses 25 and corresponding coarse adjustment ramps 251 inside, which are staggered in length to ensure that the coarse adjustment bosses 24 can be pushed out in sequence during rotation.
[0043] As can be seen from the above description, the gimbal balancing mechanism in this application, based on the existing product which only has a coarse adjustment knob 2, additionally includes a fine adjustment knob 3. Furthermore, the torque of the torque disc 4 corresponding to this fine adjustment knob 3 is less than that of the other torque discs 4. Therefore, the fine adjustment knob 3 can obtain a smaller torque force during adjustment, enabling fine-tuning. In other words, during the specific balancing operation, a smaller torque setting can be selected to counteract the gravity of the camera and receiver, resulting in more precise balance adjustment and maintaining overall balance.
[0044] As described above, this utility model provides a gimbal balance adjustment mechanism with fine-tuning function. Based on the existing adjustment knob, an additional fine-tuning knob is set up, which can control the corresponding fine-tuning torque disc, thereby obtaining smaller torque feedback and making up for the inability of existing products to achieve fine-tuning function.
[0045] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
