The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] See Figures 1-3 A preferred embodiment of the present invention provides a film shooting device for film and television production, comprising: a camera stand 1, a support base 2, a first universal joint device 3, a leveling mechanism 4, a real-time detection mechanism 5, and a control system.

[0033] The camera stand 1 is used to support the camera equipment;

[0034] The two ends of the first universal joint device 3 are respectively connected to the camera frame 1 and the support base 2;

[0035] The leveling mechanism 4 includes a telescopic leveling component 41 and two drive components 42; the two drive components 42 are slidably disposed on the support base 2 and the camera frame 1 respectively, and both drive components 42 are rotatable around the axis of the first universal joint device 3; the two ends of the telescopic leveling component 41 are respectively connected to one of the drive components 42, and the telescopic leveling component 41 is used to adjust the camera frame 1 to be parallel to the horizontal plane;

[0036] The real-time detection mechanism 5 is installed on the camera stand 1, and the real-time detection mechanism 5 is used to detect the change of the angle between the camera stand 1 and the ground on which the camera stand 1 is located in real time;

[0037] The control system is electrically connected to the leveling mechanism 4 and the real-time detection mechanism 5. The control system is used to control the operation of the telescopic leveling component 41 and the drive component 42 in the leveling mechanism 4 according to the feedback signal of the real-time detection mechanism 5.

[0038] The working principle of this invention is as follows: During operation, the photographic equipment is first installed and fixed on the camera stand 1. A flexible connection between the camera stand 1 and the support base 2 is achieved through the first universal joint device 3, allowing for flexible rotation around the axis of the first universal joint device 3. A real-time detection mechanism 5 is installed on the camera stand 1, continuously and in real-time detecting changes in the angle between the camera stand 1 and the ground, and transmitting the detected angle signal to the control system in real time. After receiving the signal, the control system quickly analyzes and determines whether the camera stand 1 is in a horizontal state. If tilt is detected, an adjustment command is immediately sent to the leveling mechanism 4. Two drive components 42 in the leveling mechanism 4 are slidably disposed on the support base 2 and the camera stand 1, respectively, and can rotate synchronously around the axis of the first universal joint device 3, forming a linkage adjustment structure with the telescopic leveling component 41. Based on the magnitude and direction of the tilt angle, the control system controls the telescopic leveling component 41 to precisely extend or shorten, while simultaneously driving the two drive components 42 to adaptively slide and adjust their positions, jointly applying a counter-compensation force to the camera stand 1 to gradually counteract the tilt deviation. Throughout the process, the real-time detection mechanism 5 continuously collects attitude signals, the control system continuously calculates adjustment commands, and the leveling mechanism 4 continuously executes adjustment actions, forming a closed-loop feedback to ensure that the camera stand 1 returns to a horizontal state in a very short time. Regardless of camera position movement, ground bumps, or external disturbances during shooting, this device can respond in real time and dynamically level, always maintaining the horizontal attitude of the camera equipment, effectively preventing tilting and shaking of the shooting image, improving the stability and smoothness of the film and television shooting, meeting the dynamic shooting needs of various complex scenarios, with a compact overall structure, rapid response, and adaptability to various film and television shooting scenarios (wherein, the control system can be a microcomputer, PLC, or single-chip microcomputer).

[0039] Obviously, based on the real-time detection mechanism 5 installed on the camera rig 1, the real-time detection mechanism 5 is used to detect the change in the angle between the camera rig 1 and the ground on which the camera rig 1 is located in real time; the control system is electrically connected to the leveling mechanism 4 and the real-time detection mechanism 5, and the control system is used to control the operation of the telescopic leveling component 41 and the drive component 42 in the leveling mechanism 4 according to the feedback signal of the real-time detection mechanism 5. This invention continuously captures the tilt angle change of the camera rig 1 through the real-time detection mechanism 5, and combines this with the control system to quickly analyze the signal and issue adjustment commands, achieving an instantaneous response to the leveling action. It can quickly capture tilt deviations during the shooting process, avoiding tilting of the shooting image due to detection lag, effectively ensuring the timeliness of real-time dynamic leveling, and improving the continuity of the shooting image.

[0040] The camera stand 1 and the support base 2 are respectively connected at both ends of the first universal joint device 3; the leveling mechanism 4 includes a telescopic leveling component 41 and two drive components 42; the two drive components 42 are slidably disposed on the support base 2 and the camera stand 1 respectively, and both drive components 42 can rotate around the axis of the first universal joint device 3; one of the drive components 42 is connected to each end of the telescopic leveling component 41, and the telescopic leveling component 41 is used to adjust the camera stand 1 to be parallel to the horizontal plane; the present invention provides a flexible posture adjustment basis through universal joint, and the telescopic leveling component 41 and the drive components 42 slide and rotate together to form a multi-degree-of-freedom linkage leveling structure, which can accurately offset tilt deviations of different directions and amplitudes, realize high-precision real-time dynamic leveling, ensure that the camera stand 1 always remains horizontal, and ensure the stability of the shooting image.

[0041] The camera stand 1 is used to support the camera equipment. The control system is electrically connected to the leveling mechanism 4 and the real-time detection mechanism 5. The control system controls the operation of the telescopic leveling component 41 and the drive component 42 in the leveling mechanism 4 based on the feedback signal from the real-time detection mechanism 5. This invention, through a closed-loop linkage structural design, achieves uninterrupted real-time dynamic leveling throughout the entire operation of the camera equipment. It can adaptively cope with various disturbances such as camera movement and ground bumps without manual intervention, reducing the workload of operators, avoiding the lag and errors of manual leveling, effectively protecting the camera equipment, adapting to various complex film and television shooting scenarios, meeting the needs of high-quality dynamic shooting, and improving shooting efficiency and work quality.

[0042] refer to Figure 1Preferably, at least two leveling mechanisms 4 are provided, and the two leveling mechanisms 4 are respectively arranged on opposite horizontal sides of the first universal joint device 3. This arrangement enables bidirectional balanced adjustment of the horizontal posture of the camera stand 1, improving the stability and accuracy of real-time dynamic leveling, and avoiding uneven force and posture deviation caused by unilateral leveling. The symmetrical arrangement can distribute the leveling load, reduce the stress on a single leveling mechanism 4, reduce the wear of the telescopic leveling component 41 and the drive component 42, and extend the service life of the device. The dual-sided leveling provides double protection. Even if one leveling mechanism 4 fails, the other can still temporarily achieve basic leveling, avoiding interruption of shooting work, adapting to the continuous operation requirements in complex shooting scenarios, and further enhancing the reliability of real-time dynamic leveling.

[0043] refer to Figure 1 Preferably, the first universal joint device 3 includes a first spherical hinge seat 31 and a first spherical hinge rod 32; one of the first spherical hinge seat 31 and the first spherical hinge rod 32 is mounted on the camera frame 1, and the other is mounted on the support base 2, with the first spherical hinge seat 31 and the first spherical hinge rod 32 spherically hinged. This arrangement allows the camera frame 1 to rotate flexibly in multiple directions without dead angles, providing more ample space for posture adjustment for real-time dynamic leveling, and avoiding the problem of incomplete leveling caused by the rotation limit of traditional hinge structures. The spherical hinge fits tightly and rotates smoothly, ensuring that the camera frame 1 can flexibly deflect around the hinge point when tilted, making the extension and drive actions of the leveling mechanism 4 smoother, reducing mechanical jamming, and improving the sensitivity of the leveling response. At the same time, the spherical contact can distribute the force at the hinge point, reduce local wear, enhance the load-bearing capacity of the hinge structure, adapt to the weight load of the photography equipment, and prevent loosening and deformation after long-term use. Wear-resistant bushings or lubricating layers can be installed at the spherical hinge to further reduce rotational friction, improve structural stability and service life, and ensure long-term reliable operation of the real-time dynamic leveling function.

[0044] refer to Figure 1 and Figure 2Preferably, the drive assembly 42 includes a movable support frame 421, a drive motor 422, and a drive wheel 423. The support base 2 and the camera stand 1 are each provided with a circular guide groove 6, the center of which coincides with the axis of the first spherical hinge rod 32. The telescopic leveling assembly 41 is connected to the movable support frame 421. The drive motor 422 is mounted on the movable support frame 421 and drives the drive wheel 423, which is located within the circular guide groove 6 and rolls in contact with it. This configuration allows for precise and smooth rotation of the drive assembly 42 around the axis of the first spherical hinge rod 32, ensuring coordinated operation between the drive assembly 42 and the leveling mechanism 4, providing a stable motion foundation for real-time dynamic leveling. The circular guide groove 6 is coaxially arranged with the first spherical hinge rod 32, strictly limiting the movement trajectory of the drive wheel 423, preventing leveling deviations caused by drive assembly 42 offset, and improving leveling accuracy. The rolling mechanism significantly reduces driving resistance, enabling efficient power transmission from the drive motor 422, accelerating the adjustment speed of the drive assembly 42, and improving leveling response efficiency. The movable support frame 421 stably supports the telescopic leveling assembly 41 and the drive motor 422, distributing the force and preventing local structural overload damage. The drive wheel 423 can be made of wear-resistant rubber or metal rollers; the drive motor 422 can be a stepper motor or a servo motor.

[0045] refer to Figure 2 Preferably, the drive wheel 423 is a gear, and the wall of the circular guide groove 6 is provided with grooved teeth 61, which mesh with each other. This arrangement enables precise transmission and positioning of the drive assembly 42 around the axis of the first spherical hinge rod 32, completely eliminating the slippage and offset problems that are prone to occur in traditional rolling fits, and providing a stable and reliable power transmission guarantee for real-time dynamic leveling. The meshing of the gear and the grooved teeth 61 can strictly limit the rotation trajectory and angle of the drive assembly 42, ensuring precise and controllable drive action, greatly improving the accuracy of real-time dynamic leveling, and avoiding untimely or incomplete leveling due to drive deviation. The meshing structure is evenly stressed, which can effectively distribute the drive load, reduce local wear of the gear and the grooved teeth 61, and extend the service life of the drive assembly 42. Among them, the gear and the grooved teeth 61 can be made of high-strength wear-resistant alloy material, and the meshing surface can be carburized and lubricated to further improve the smoothness of transmission and structural stability, ensuring the long-term stable operation of the real-time dynamic leveling function.

[0046] refer to Figure 1 and Figure 2Preferably, the telescopic leveling assembly 41 includes an adjusting motor 411, an adjusting lead screw 412, and an adjusting sleeve 413. The adjusting motor 411 and the adjusting sleeve 413 are respectively connected to the movable support frame 421 of the two drive assemblies 42. The output shaft of the adjusting motor 411 drives the adjusting lead screw 412, which can rotate with the output shaft of the adjusting motor 411. The adjusting sleeve 413 is sleeved on the adjusting lead screw 412 and is threadedly connected to the adjusting lead screw 412. The adjusting sleeve 413 can move as the adjusting lead screw 412 rotates. This configuration enables precise telescopic adjustment of the telescopic leveling assembly 41, providing stable and controllable adjustment power for real-time dynamic leveling, ensuring that the leveling action accurately adapts to the tilt deviation of the camera stand 1. The adjusting motor 411 drives the adjusting screw 412 to rotate. Through the cooperation between the screw and the sleeve, the rotational motion is converted into linear telescopic motion, resulting in high adjustment precision and controllable stroke. The telescopic length can be precisely adjusted according to the instructions of the control system, achieving accurate compensation for the tilt deviation of the camera stand 1. The cooperation between the adjusting screw 412 and the adjusting sleeve 413 has a self-locking function, which can stably maintain the telescopic length after leveling, preventing leveling failure due to external disturbances and ensuring the stability of the horizontal posture of the camera stand 1. The telescopic leveling assembly 41 also includes a guide mechanism for guiding the adjusting sleeve 413 to move along the adjusting screw 412. Specifically, the guide mechanism can be a structure of sliding cooperation between a guide rail and a slider, or a structure of sliding cooperation between a guide post and a guide sleeve. The adjusting screw 412 can be a high-precision ball screw; the inner wall of the adjusting sleeve 413 can be provided with wear-resistant threads; and the adjusting motor 411 can be a stepper motor or a servo motor.

[0047] refer to Figure 1 and Figure 2Preferably, the adjusting motor 411 and the adjusting sleeve 413 are respectively hinged to the movable support frame 421 in one of the drive components 42. This arrangement enables a flexible connection between the telescopic leveling component 41 and the movable support frame 421, effectively adapting to the rotation of the drive component 42 around the first spherical hinge rod 32, and avoiding structural interference or jamming between components during the leveling process. The adjusting motor 411 and the adjusting sleeve 413 are respectively hinged to the corresponding movable support frame 421, allowing for flexible adaptation to the rotational posture of the movable support frame 421. Simultaneously, it allows the telescopic leveling component 41 to adaptively adjust its angle according to the tilt angle of the camera stand 1 during telescopic adjustment, ensuring that the adjusting screw 412 and the adjusting sleeve 413 always maintain precise fit, guaranteeing smooth power transmission, and preventing component wear or leveling failure due to angular deviation. The hinged structure effectively disperses the radial load generated during leveling, reducing the stress on the connection between the movable support frame 421 and the telescopic leveling component 41, lowering the risk of structural damage, and improving the overall operational stability of the mechanism. The hinge can be a universal hinge or a pin hinge structure. Wear-resistant bushings can be installed at the hinge and lubricated to reduce frictional resistance and reduce component wear.

[0048] refer to Figure 3Preferably, the real-time detection mechanism 5 includes a mounting plate 51, a second universal joint device 52, a movable plate 53, and a detection sensor 54. The mounting plate 51 is mounted on the camera stand 1. The two ends of the second universal joint device 52 are respectively connected to the mounting plate 51 and the movable plate 53. The movable plate 53 has a pointing rod 531, the pointing direction of which always coincides with the direction of gravity. The detection sensor 54 is provided on one of the mounting plate 51 and the movable plate 53, and an annular sensing layer 55 that cooperates with the detection sensor 54 is provided on the other. The center of the annular sensing layer 55 coincides with the axis of the second universal joint device 52. When the end face of the mounting plate 51 is parallel to the end face of the movable plate 53, the detection sensor 54 can detect the annular sensing layer 55. This configuration enables precise and real-time detection of the tilt angle of the camera stand 1, providing reliable signal support for real-time dynamic leveling and effectively ensuring the accuracy and timeliness of the detection results. The second universal joint device 52 allows the movable plate 53 to rotate flexibly around the mounting plate 51. Combined with the characteristic that the pointing rod 531 always points in the direction of gravity, this ensures that the movable plate 53 maintains a stable posture, unaffected by the tilt of the camera stand 1. This, in turn, ensures precise coordination between the annular sensing layer 55 and the detection sensor 54. The coordination between the detection sensor 54 and the annular sensing layer 55 can quickly capture the angular deviation between the mounting plate 51 and the movable plate 53, i.e., the tilt deviation of the camera stand 1. Furthermore, the annular sensing layer 55 and the second universal joint device 52 are coaxially arranged, allowing for accurate detection of tilt in different directions and avoiding blind spots. The detection sensor 54 can be an infrared sensor or a Hall sensor, and the annular sensing layer 55 can be a conductive sensing layer, further improving detection accuracy and stability and ensuring reliable real-time dynamic leveling.

[0049] refer to Figure 3Preferably, the second universal joint device 52 includes a second spherical hinge seat 521 and a second spherical hinge rod 522; one of the second spherical hinge seat 521 and the second spherical hinge rod 522 is mounted on the mounting plate 51, and the other is mounted on the movable plate 53, and the second spherical hinge seat 521 and the second spherical hinge rod 522 are spherically hinged; the second spherical hinge seat 521 is provided with an injection port 523, which is used to inject lubricating fluid or lubricating oil. This arrangement allows the movable plate 53 to rotate flexibly and smoothly in multiple directions around the mounting plate 51, providing a stable hinge foundation for the real-time detection mechanism 5 to accurately capture the tilt deviation of the camera stand 1, and effectively avoiding hinge jamming that affects detection accuracy. The spherical hinge of the second spherical hinge seat 521 and the second spherical hinge rod 522 allows the movable plate 53 to tilt flexibly with the camera stand 1, ensuring that the pointing rod 531 always points precisely in the direction of gravity, guaranteeing the matching accuracy of the detection sensor 54 and the annular sensing layer 55, thereby improving the accuracy of real-time detection. The injection port 523 allows for convenient injection of lubricant or oil into the hinge area, continuously reducing frictional resistance at the spherical hinge, preventing wear and jamming over long-term use, and extending the service life of the second universal hinge device 52. Simultaneously, regular lubrication maintains the flexibility and stability of the hinge structure, ensuring smooth adjustment of the movable plate 53's posture, timely transmission of detection signals, and providing reliable detection assurance for real-time dynamic leveling. The injection port 523 can be fitted with a sealing plug to prevent lubricant leakage, further improving the structure's sealing and practicality.

[0050] refer to Figure 1Preferably, the support base 2 is connected to a shock-absorbing device 7; the shock-absorbing device 7 includes a telescopic sleeve 71, a connecting plate 72, and multiple shock-absorbing springs 73; the telescopic sleeve 71 is installed on the support base 2; the telescopic sleeve 71 connects to the connecting plate 72 and supports the connecting plate 72; the two ends of the shock-absorbing springs 73 are respectively connected to the support base 2 and the connecting plate 72, and the multiple shock-absorbing springs 73 are distributed circumferentially at intervals around the axis of the telescopic sleeve 71; the first universal hinge device 3 and the leveling mechanism 4 are respectively installed on the connecting plate 72; the support base 2 is also pivotally connected to multiple universal wheels 8. This arrangement can effectively buffer the vibrations caused by ground bumps and external impacts during shooting, provide a stable installation foundation for real-time dynamic leveling, and avoid vibrations causing the camera stand 1 to tilt, the detection signal to be distorted, or the leveling mechanism 4 to malfunction. The telescopic sleeve 71, in conjunction with multiple circumferentially distributed shock-absorbing springs 73, provides stable support for the connecting plate 72 and absorbs vibrations from all directions, reducing the transmission of vibrations to the first universal joint device 3 and the leveling mechanism 4 on the connecting plate 72. This ensures smooth operation of all leveling components and improves the accuracy and reliability of real-time dynamic leveling. The casters 8 allow for flexible movement of the entire shooting device, facilitating adjustments to the camera position to adapt to different shooting scenarios. The pivot design does not affect the cushioning effect of the shock-absorbing device 7, balancing mobility and operational stability. The shock-absorbing springs 73 can be high-strength compression springs, the inner wall of the telescopic sleeve 71 can be coated with a wear-resistant coating, and the casters 8 can be casters with brakes.
