[0055] Maintaining the balance of the camera equipment is crucial for achieving high-quality images or video capture during photography. Especially when batteries or other accessories are installed, the stabilizer's center of gravity may shift, causing the equipment to tilt or become unstable. Existing center of gravity adjustment technologies typically employ a two-way sliding mechanism, requiring users to repeatedly loosen, push, and lock the slider to adjust the center of gravity. This method is cumbersome, complex, and costly. Therefore, an improved center of gravity adjustment device is proposed, providing a more convenient and efficient method for adjusting the center of gravity. For details, please refer to [link / reference].

[0056] This utility model embodiment proposes a center of gravity adjustment device 20, applied to a camera stabilizer 10. The camera stabilizer 10 includes a support rod 100, which has a first connecting end 101 and a second connecting end 102. The first end is used to mount photographic equipment or camera accessories, and the center of gravity adjustment device is disposed on the second connecting end. The center of gravity adjustment device 20 includes:

[0057] The mounting seat 200 includes opposite first and second ends, and the first end of the mounting seat 200 is configured to connect the photographic device;

[0058] The first counterweight 300 is connected to the second connecting end 102 of the mounting seat 200, and the first counterweight 300 is configured to reciprocate along the first direction F relative to the mounting seat 200.

[0059] The first adjusting assembly 400 is connected to one side of the mounting seat 200 and in contact with the first counterweight, and the first adjusting assembly 400 is configured to drive the first counterweight 300 to reciprocate along the first direction F relative to the mounting seat 200 under the action of an external force.

[0060] The gravity center adjusting device 20 according to the embodiment is applied to the photographic stabilizer 10, and the stabilizer includes a support rod 100 having a first connecting end 101 and a second connecting end 102 for supporting and connecting different photographic devices and accessories. The gravity center adjusting device 20 includes a mounting seat 200 mounted to the second connecting end 102 of the support rod 100 for providing a stable support and mounting platform. The mounting seat 200 can be designed in a square or circular shape according to actual needs, and can be made of lightweight high-strength materials such as aluminum alloy or carbon fiber to reduce the overall weight and enhance stability.

[0061] The first counterweight 300 is mounted on the side of the mounting seat 200 opposite to the second connecting end 102, and functions to adjust the gravity center of the photographic stabilizer 10 by moving in a specific direction. The first counterweight 300 is usually in the shape of a cuboid or a column, and can be made of high-strength metal materials or wear-resistant engineering plastics to ensure durability and stability during adjustment.

[0062] The first adjusting assembly 400 is mounted on the mounting seat 200 and is configured to drive the first counterweight 300 to reciprocate along the first direction F under the action of an external force, thereby achieving adjustment of the gravity center. The first adjusting assembly 400 can adopt a screw structure, and the first counterweight 300 is driven to move relative to the mounting seat 200 by rotating the screw thread, thereby accurately adjusting the gravity center position of the entire photographic stabilizer 10.

[0063] Further, a mounting plate can be detachably mounted on the side of the first counterweight 300 opposite to the mounting seat 200, for mounting other components, for example, further increasing the counterweight, or mounting auxiliary devices such as batteries, lighting equipment, etc., which are not particularly limited here.

[0064] When the user needs to adjust the center of gravity of the camera stabilizer 10, the user only needs to operate the first adjustment assembly 400, which can drive the first counterweight 300 to move relative to the mounting base 200 by rotating the screw rod, so as to realize fine adjustment of the center of gravity. For example, when the battery, lighting equipment or other auxiliary devices (such as an external microphone, a monitor) are installed on the stabilizer, the overall center of gravity may change. At this time, the user can quickly move the first counterweight 300 to the appropriate position by adjusting the first adjustment assembly 400 to rebalance the entire stabilizer and ensure stability and smoothness during shooting. In addition, in actual operation, the user can achieve precise adjustment through the first adjustment assembly 400 without the need for additional tools to easily balance the center of gravity. This simple and intuitive adjustment process is suitable for various shooting scenarios, including outdoor shooting, dynamic motion scenes, and complex shooting environments with multiple accessory combinations, thereby greatly improving the convenience and stability of shooting.

[0065] The beneficial effects of the technical scheme of the utility model lie in that, through the combination of the mounting base 200, the first counterweight 300 and the first adjustment assembly 400, efficient and convenient center of gravity adjustment is realized. The mounting base 200 provides stable support to ensure the accuracy of the counterweight during movement, the first counterweight 300 enables the user to flexibly adjust the center of gravity to adapt to different accessory weights and adjust the center of gravity position, and the first adjustment assembly 400 adopts mechanical transmission, which can be easily adjusted by the user with small external force, avoiding the cumbersome operation in the prior art, improving the adjustment efficiency and reducing the complexity.

[0066] Continuing to refer to Figure 5 In this embodiment, the second end 402b of the mounting base 200 is configured with a receiving cavity 202, the receiving cavity 202 has opposite first and second side walls 204 and 206, and the first counterweight 300 is at least partially located in the receiving cavity 202.

[0067] The first adjustment assembly 400 comprises:

[0068] The transmission rod 402 is in transmission connection with the part of the first counterweight 300 located in the receiving cavity 202 through the side wall of the receiving cavity 202, and the transmission rod 402 is configured to rotate under the action of external force to drive the first counterweight 300 to reciprocate relative to the mounting base 200 along the first direction F.

[0069] In this embodiment, the side of the mounting base 200 opposite to the second connecting end 102 is configured with a receiving cavity 202, the receiving cavity 202 has opposite first and second side walls 204 and 206. The first counterweight 300 is at least partially located in the receiving cavity 202, which ensures that it is limited to a specific path during adjustment, thereby realizing accurate movement.

[0070] The first adjusting assembly 400 comprises a transmission rod 402, which penetrates the first side wall 204, the second side wall 206 and the first counterweight 300 located in the accommodating cavity 202. In this way, the transmission rod 402 is connected with the first counterweight 300 in the accommodating cavity 202, so that the rotation of the transmission rod 402 can directly affect the movement of the first counterweight 300.

[0071] Specifically, the two ends of the transmission rod 402 are arranged on the first side wall 204 and the second side wall 206, respectively. Through the action of external force (for example, manual rotation or motor driving can be used), the transmission rod 402 will rotate. The threaded structure of the transmission rod 402 can form a threaded fitting relationship with the first counterweight 300. When the transmission rod 402 rotates, the first counterweight 300 will reciprocate along the axial direction of the transmission rod 402 due to the action of the thread, thereby realizing movement adjustment in the first direction F relative to the mounting base 200. This way not only improves the accuracy of adjustment, but also through the design of mechanical transmission, the user can realize accurate adjustment of the center of gravity of the stabilizer under the action of small external force.

[0072] In addition, the design of the accommodating cavity 202 ensures that the first counterweight 300 will not deviate during movement and always move in the predetermined direction, avoiding adjustment errors caused by deviation. This stable guiding structure cooperates with the mechanical transmission of the transmission rod 402 to make the whole adjustment process smoother and more efficient. At the same time, the material of the transmission rod 402 can be high-strength alloy material to ensure that it will not wear or deform during long-term use, thereby maintaining the reliability and durability of the adjustment.

[0073] In summary, the embodiment optimizes the cooperation structure of the transmission rod 402 and the first counterweight 300 to realize convenient adjustment of the center of gravity of the photographic stabilizer 10, so that the user can quickly and accurately adjust the center of gravity, reduce unnecessary cumbersome operation, and improve the stability of the entire shooting system and user experience.

[0074] Continuing to refer to Figure 5 In the embodiment, the side of the first counterweight 300 facing the accommodating cavity 202 is configured with a protrusion 302, and the protrusion 302 is configured with a threaded hole 302a, and the transmission rod 402 is threadedly connected with the threaded hole 302a.

[0075] In the embodiment, the side of the first counterweight 300 facing the accommodating cavity 202 is configured with a protrusion 302. The protrusion 302 is designed to have a certain protruding part, so that it can form a firm mechanical connection with the transmission rod 402 in the accommodating cavity 202.

[0076] Specifically, the protrusion 302 is configured with a threaded hole 302a, and the transmission rod 402 is threadedly connected with the threaded hole 302a. Through this threaded connection mode, when the transmission rod 402 rotates, the rotational movement of the thread will be transmitted to the first counterweight 300, so that the counterweight reciprocates along the axial direction of the transmission rod 402. This design not only enhances the stability of transmission, but also greatly improves the accuracy of the gravity center adjustment, ensuring that users can obtain more intuitive and sensitive feedback when operating.

[0077] In addition, the thread matching accuracy between the transmission rod 402 and the threaded hole 302a can be adjusted according to actual needs to achieve different adjustment effects. For example, fine threads can be used to obtain more precise gravity adjustment, which is suitable for scenarios that require high-precision control. Coarse threads can provide relatively fast adjustment, which is suitable for scenarios that require high speed. In addition, in order to reduce the frictional resistance that may be generated during adjustment, the threaded part of the protrusion 302 and the transmission rod 402 can be treated with special lubricating materials to further improve the smoothness of the adjustment process.

[0078] The embodiment realizes high precision and high efficiency of the stabilizer gravity center adjustment through the threaded connection between the protrusion 302 and the transmission rod 402, simplifies the structure design, reduces additional guide components, and thus reduces the manufacturing cost and maintenance difficulty of the overall device.

[0079] Continuing to refer to Figure 5 In the embodiment, the side wall of the accommodating cavity includes oppositely arranged first and second side walls 204 and 206, the first side wall 204 is configured with a first through hole 204a, and the second side wall 206 is configured with a second through hole 206a, the first through hole 204a and the second through hole 206a are opposite, and the transmission rod 402 passes through the second through hole 206a and the first through hole 204a in sequence.

[0080] Among them, the transmission rod can rotate in the first through hole 204a and the second through hole 206a under the action of external force to drive the first counterweight 300 to move.

[0081] In the embodiment, the connection and movement mode of the transmission rod 402 and the first counterweight 300 are further optimized to realize more smooth and accurate gravity center adjustment. Specifically, the first side wall 204 is configured with a first through hole 204a, and the second side wall 206 is configured with a second through hole 206a, the two through holes are opposite to each other and form a through structure. The transmission rod 402 passes through the second through hole 206a and the first through hole 204a in sequence, so as to rotate freely between the two side walls of the mounting seat 200.

[0082] In this way, the transmission rod 402 can freely rotate in the first through hole 204a and the second through hole 206a under the action of an external force. When the transmission rod 402 rotates, the first counterweight 300 moves back and forth along the axial direction of the transmission rod 402 due to the threaded connection between the transmission rod 402 and the first counterweight 300. This design ensures that the counterweight can be smoothly adjusted under the action of the transmission rod 402, avoiding adjustment errors caused by unstable structure.

[0083] To further improve the smoothness and durability of the adjustment, the contact part of the transmission rod 402 with the through hole can be coated with a high-performance lubricating material, such as a Teflon coating, which can effectively reduce friction and improve the smoothness of the transmission rod 402 rotation, thereby making the first counterweight 300 more flexible during movement. In addition, the transmission rod 402 can be made of stainless steel or high-strength alloy material to ensure that it does not deform or wear during long-term use, thereby maintaining the stability and reliability of the system.

[0084] The present embodiment provides through holes in the first side wall 204 and the second side wall 206 of the mounting seat 200, so that the transmission rod 402 can smoothly pass through the two through holes and freely rotate, cooperating with the threaded structure to drive the first counterweight 300 to move. This design makes the gravity adjustment more intuitive and simple, and reduces unnecessary friction and structural obstacles during operation, significantly improving the adjustment efficiency and user experience of the device.

[0085] Continuing to refer to Figure 5 , the transmission rod 402 has a first end 402a located in the first through hole 204a and a second end 402b extending out of the second through hole 206a;

[0086] The first adjustment assembly 400 further includes a first shaft sleeve 404 and a second shaft sleeve 406, the first shaft sleeve 404 being installed in the first through hole 204a, and the second shaft sleeve 406 being installed in the second through hole 206a.

[0087] In the present embodiment, the first adjustment assembly 400 not only includes the transmission rod 402, but also includes the first shaft sleeve 404 and the second shaft sleeve 406. The first shaft sleeve 404 is installed in the first through hole 204a, and the second shaft sleeve 406 is installed in the second through hole 206a. The first shaft sleeve 404 and the second shaft sleeve 406 serve to provide support and guidance for the transmission rod 402, so that the transmission rod 402 can remain stable during rotation and avoid shaking or jamming.

[0088] Specifically, the first shaft sleeve 404 is sleeved on the first end 402a of the transmission rod 402 and located inside the mounting seat 200, which can provide a stable fulcrum for the transmission rod 402. The second shaft sleeve 406 is sleeved on the second end 402b of the transmission rod 402 and extends outside the mounting seat 200, which is convenient for the user to exert an external force on the transmission rod 402 for operation. Under the action of the external force, the transmission rod 402 is configured to rotate in the first shaft sleeve 404 and the second shaft sleeve 406, thereby driving the first counterweight 300 to move back and forth along the axial direction of the transmission rod 402. The first shaft sleeve 404 and the second shaft sleeve 406 can be made of high wear-resistant materials, such as copper-based alloys or composite plastics, to ensure that they are not easily worn out during high-frequency operation and prolong the service life of the overall system.

[0089] The embodiment ensures the stability and flexibility of the transmission rod 402 during operation by providing the first shaft sleeve 404 and the second shaft sleeve 406 at both ends of the transmission rod 402, and effectively reduces the frictional resistance during adjustment. This design allows the user to operate the transmission rod 402 more easily, thereby adjusting the center of gravity of the photographic stabilizer 10.

[0090] Referring to Figure 5 and Figure 6 In the embodiment, the first adjustment assembly 400 further includes:

[0091] The locking member 408 is arranged at the first end 402a of the transmission rod 402.

[0092] The knob 410 is arranged at the second end 402b of the transmission rod 402.

[0093] The locking member 408 and the knob 410 are configured to prevent the transmission rod 402 from moving in the first direction F.

[0094] In the embodiment, the first adjustment assembly 400 further includes the locking member 408 and the knob 410 in addition to the transmission rod 402, the first shaft sleeve 404 and the second shaft sleeve 406, to improve the stability of the transmission system and the safety of user operation.

[0095] Specifically, the locking member 408 is arranged at the first end 402a of the transmission rod 402 and located inside the first through hole 204a. Its main function is to prevent the transmission rod 402 from moving in the first direction F by providing sufficient clamping force, thereby ensuring that the transmission rod 402 does not axially displace due to external force during operation. The locking member 408 can adopt a spring-loaded clamping structure, a mechanical locking structure or a nut, etc., to be adjusted and locked conveniently without tools. Such a design allows the user to quickly lock the transmission rod 402 after completing the center of gravity adjustment, ensuring the stability of its position.

[0096] The knob 410 is arranged at the second end 402b of the transmission rod 402 and extends out of the mounting base 200, so as to facilitate manual operation by the user. The knob 410 is designed to allow the user to easily apply a rotating force to the transmission rod 402, thereby achieving adjustment of the center of gravity. The knob 410 can be provided with an anti-slip design, such as knurling or rubber coating, to increase the comfort and stability of gripping.

[0097] The combination of the locking member 408 and the knob 410 ensures that the transmission rod 402 can be kept in a predetermined position during rotation, while preventing unnecessary movement in the first direction F. This not only improves the safety and stability of the overall structure, but also provides a more intuitive and reliable operation mode in terms of user experience, reduces errors and inconvenience caused by displacement of the transmission rod 402 during center of gravity adjustment, and makes the entire device more suitable for use in complex shooting environments.

[0098] The present embodiment achieves effective control of the transmission rod 402 and enhances the stability and safety of the center of gravity adjustment device 20 during use, greatly reducing the problem of unstable shooting caused by accidental displacement of the transmission rod 402, and improving the convenience of center of gravity adjustment.

[0099] Referring to Figure 7 In the present embodiment, the first counterweight member 300 is configured with a protrusion 302 on the side facing the accommodating cavity 202, the protrusion 302 is configured with a threaded hole 302a, and the transmission rod 402 is threadedly connected with the threaded hole 302a; the first adjustment assembly 400 further comprises at least one guide column 412, one end of the guide column 412 is connected with the first side wall 204, and the other end of the guide column 412 passes through the protrusion 302 and is connected with the second side wall 206, the guide column 412 is used for guiding the movement of the first counterweight member 300.

[0100] In the present embodiment, the guide column 412 is provided to provide a fixed movement track for the first counterweight member 300, ensuring that the counterweight member can move stably and in a predetermined direction when the transmission rod 402 drives the first counterweight member 300 to move in the axial direction, avoiding possible deviation or tilting. Through the guiding action of the guide column 412, the first counterweight member 300 can move in a straight line during movement, thereby ensuring that the entire system maintains high precision and stability during adjustment.

[0101] In addition, the guide column 412 can also enhance the lateral force resistance of the counterweight during movement, reducing the vibration and unnecessary shaking that may be caused by external forces. Among them, the guide column 412 can be made of high-strength alloy steel or other materials with high rigidity and wear resistance to ensure that it is not easily deformed or worn out during long-term use, prolonging the service life of the overall system. In order to further improve the smoothness of movement, the surface of the guide column 412 can be finely surface treated, such as electroplated or coated with a lubricating layer, to reduce friction and make the first counterweight 300 move more smoothly.

[0102] The present embodiment realizes effective guidance of the first counterweight 300 and enhances the stability and lateral interference resistance during movement by adding at least one guide column 412 in the first adjustment assembly 400. This design greatly reduces positional deviation and unnecessary shaking during adjustment, significantly improves the accuracy of gravity center adjustment and the convenience of user operation, and provides a more reliable gravity center control means for users in various complex shooting environments.

[0103] Referring to Figure 2 , Figure 3 and Figure 5 , in the present embodiment, the gravity center adjustment device 20 further includes a second counterweight 500 and a second adjustment assembly 600 disposed on the first adjustment assembly 400, the second counterweight 500 is disposed on the side of the first counterweight 300 opposite the mounting seat 200, and the second counterweight 500 can move relative to the first counterweight 300 along a second direction E.

[0104] Among them, the second adjustment assembly 600 is configured to move the second counterweight 500 relative to the first counterweight 300 along the second direction E under the action of external force.

[0105] In the present embodiment, the gravity center adjustment device 20 further optimizes and expands the function of gravity center adjustment, and realizes bidirectional gravity center adjustment by introducing the second counterweight 500 and the second adjustment assembly 600, thereby providing more comprehensive balance control capability. Among them, the gravity center adjustment device 20 includes the first counterweight 300 and the first adjustment assembly 400 disposed on the mounting seat 200, which is used for gravity center adjustment along the first direction F (e.g. left-right direction). In addition, the present embodiment further includes the second counterweight 500 and the second adjustment assembly 600 to further realize gravity center adjustment along the second direction E (e.g. front-back direction).

[0106] Specifically, the second counterweight 500 is arranged on the side of the first counterweight 300 opposite to the mounting base 200. In this way, the second counterweight 500 can cooperate with the first counterweight 300 to adjust the movement in the second direction E. The second direction E can be perpendicular to the first direction F, so that the overall center of gravity can be adjusted in two dimensions to achieve the best balance effect. The second adjustment assembly 600 is configured to drive the second counterweight 500 to reciprocate relative to the first counterweight 300 in the second direction E under the action of an external force, thereby accurately adjusting the center of gravity.

[0107] In actual operation, when the user needs to adjust the center of gravity of the device, the first adjustment assembly 400 can be used to perform coarse adjustment in the first direction F, such as left-right balance adjustment. After the preliminary adjustment is completed, the user can further adjust the second counterweight 500 through the second adjustment assembly 600 to achieve precise control in the front-back direction. This two-axis adjustment design allows the entire device to adapt to more complex shooting environments. For example, when the device is equipped with various accessories of different weights, the user can accurately find the optimal center of gravity position through two-axis adjustment, thereby effectively improving the shooting stability.

[0108] The structure of the second adjustment assembly 600 can adopt various forms such as threaded transmission and sliding block guide to achieve fine control of the second counterweight 500.

[0109] In summary, the embodiment increases the second counterweight 500 and the second adjustment assembly 600 to achieve accurate adjustment of the center of gravity in two directions, so that the device can quickly adapt and maintain balance in complex use environments. This two-axis adjustment design not only improves the stability and flexibility of the device, but also significantly improves the user experience, making the center of gravity adjustment process more convenient and accurate, and providing users with more efficient shooting control means.

[0110] Further, the second counterweight 500 has the same structure as the first counterweight 300, and the second adjustment assembly 600 has the same structure as the first adjustment assembly 400.
