[0002] A pan-tilt head is a support device for video recording equipment such as cameras and camcorders. During the shooting process, it is necessary to quickly install and fix the video recording equipment.

[0003] To meet different shooting needs, such as tilting or rotating to shoot at different angles in different horizontal directions, the gimbal needs to be able to adjust in various directions during use. However, the gimbal adjustment structure of some existing camera equipment is complex and cumbersome to operate, making the adjustment process inflexible and inefficient, and unable to achieve dynamic balance during the adjustment process.

[0010] In one possible implementation, the angle adjustment mechanism includes a worm gear, a worm, and a knob. One end of the worm is connected to the knob, and the other end of the worm meshes with the worm gear. The worm gear is fixed to the outer wall of the connecting ring, thereby rotating the swashplate by rotating the worm gear to drive the worm gear to rotate.

[0011] In one possible implementation, the pitch mount includes a support ring, a support plate, and a plate base arranged opposite to each other. The plate base is disposed on top of the support ring and the support plate. The support plate is fixedly connected to the rotor of the swashplate dynamic balance adjustment assembly, thereby constituting the pitch motion of the gimbal and supporting the camera / video recording equipment.

[0012] In one possible implementation, the stator has a coaxial ring sleeve with a notch at one end near the support plate, and a first damping adjustment component is provided inside the ring sleeve. The rotor has a first concentric ring groove at one end near the support plate. The first damping adjustment component includes a first movable concentric ring and a first adjusting ring. The first movable concentric ring has a protrusion that matches the notch, and the outer contour of the protrusion is a coaxial cylindrical surface with external threads. The first adjusting ring has internal threads that cooperate with the protrusion. The space between the first movable concentric ring and the wall of the first concentric ring groove is filled with damping oil. The first movable concentric ring is driven to insert into or move away from the first concentric ring groove by the first adjusting ring to realize the damping adjustment during the pitch adjustment process of the pitch frame.

[0013] In one possible implementation, a stator end cover is provided between the support plate and the stator, and a locking knob ring is provided on the support plate.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a swashplate dynamic balance adjustment component and a stepless adjustment gimbal, which has the following beneficial effects:

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-4This is a structural schematic diagram of the swashplate dynamic balance adjustment assembly and its specific components in this invention. The swashplate dynamic balance adjustment assembly includes a stator 20, a rotor 21, a swashplate assembly 22, and an angle adjustment mechanism 23. The rotor 21 is disposed in the cavity of the stator 20 and can rotate within the stator 20. An eccentric hole 201 extending along its axial direction is provided in the stator 20. The swashplate assembly 22 includes a swashplate 220, a universal joint slide 221, and an elastic element 222. The fixed end of the elastic element 222 is disposed in the eccentric hole 201, and the movable end of the elastic element 222 extends out of the eccentric hole 201 and is connected to the universal joint slide 221. The bottom surface of the universal joint slide 221 abuts against the surface of the swashplate. The swashplate 220 is rotatably fixed in the stator 20 by a horizontal rotating shaft 223 perpendicular to the rotor shaft. One side of the swashplate 220 is connected to the angle adjustment mechanism 23, which adjusts the angle between the swashplate 220 and the rotating end face of the rotor.

[0032] In one possible implementation, the universal joint slide 221 includes a ball seat 211, a ball 212, and a connecting rod 213. The ball seat 211 is movably provided with the ball 212. The ball 212 is inserted into and fixed to the piston 2B through the connecting rod 213. The bottom surface of the ball seat 211 abuts against the swashplate surface.

[0033] Based on the structural design of the swashplate dynamic balance adjustment component of this invention, the ball of the universal joint slide can rotate freely within the ball seat, while the bottom surface of the ball seat slides and rubs against the inner surface of the swashplate. When the swashplate and the rotor end face are at a certain angle (i.e., non-parallel), when the rotor starts to rotate from the lower equilibrium position (zero degrees), it drives the universal joint slide to make a circular motion along the surface of the swashplate. Since the swashplate and the rotor rotation end face are at a certain angle, the distance between the universal joint slide and the rotor end face gradually decreases, causing the elastic element to be compressed. Thus, under the reaction force of the elastic element, the eccentric distance of the elastic element provides a reverse torque. When the swashplate and the rotor rotation end face are parallel (the angle is zero), the distance between the swashplate and the rotor rotation end face is constant. No matter how the rotor rotates, it will not compress the elastic element, and the reverse torque is zero at this time. When the angle between the swashplate and the rotor rotation end face is adjusted to the maximum, when rotating to the limit value ±90 degrees, the compression difference of the elastic element reaches the maximum, the reverse torque reaches the maximum, and the dynamic balance capability also reaches the maximum.

[0034] However, in practical applications, if it is necessary to selectively achieve the reverse torque to act only upwards or only downwards, then a limiting mechanism needs to be set in the angle adjustment of the swashplate. For example, it can be limited to rotating only upwards to form a maximum of +90 degrees, or rotating only downwards to form a maximum of -90 degrees. This patent does not limit the specific setting of the limiting mechanism.

[0035] The elastic element in this invention can be any existing elastic element, such as a gas spring or a spring group composed of multiple springs. It is acceptable as long as it can work in conjunction with the adjusting component of this invention to achieve the desired effect. For example, it can be a nitrogen spring or a hydropneumatic spring. The accompanying drawings of this invention primarily illustrate a gas spring as the elastic element, but this is not a limitation.

[0036] When the elastic element is a gas spring, the cylinder 2A of the gas spring is set in the eccentric hole 201, the piston 2B of the gas spring is slidably connected to the inner cavity of the cylinder 2A, and the other end of the piston 2B extends out of the eccentric hole 201 and is connected to the universal joint slide 221.

[0037] In one possible implementation, the swash plate 220 is connected to two connecting rings 224 on both sides. The connecting rings 224 are provided with shaft holes. The swash plate 220 is rotated and fixed in the stator 20 by the cooperation of the horizontal rotating shaft 223 with the shaft hole 225.

[0038] The swash plate can be welded to connecting rings on both sides, or it can be manufactured into a single integrated structure. Its main purpose is to provide a connecting component for the swash plate to rotatably connect with the stator. Alternatively, the connecting rings can be omitted, and the two sides of the swash plate can be machined into shafts, with one shaft having a threaded outer wall. Specific structural implementations are not the focus of this invention and will not be listed here.

[0039] The angle between the swashplate and the rotor's rotating end face can be adjusted by an angle adjustment mechanism. This angle adjustment mechanism can be any existing mechanism used to drive the swashplate to rotate. The specific structural form of the angle adjustment mechanism is not limited, as long as it can drive the swashplate to rotate and thus change the angle between the swashplate and the rotor's rotating end face.

[0040] However, to further clarify the technical implementation of this application, the embodiments of this application further provide a specific structure of one angle adjustment mechanism. In one possible implementation, the angle adjustment mechanism 23 includes a worm gear 311, a worm 312, and a knob 313. One end of the worm 312 is connected to the knob 313, and the other end of the worm 312 is engaged with the worm gear 311. The worm gear 311 is fixedly connected to the outer wall of the connecting ring 224, thereby rotating the swashplate 220 by rotating the worm gear 312 to drive the worm gear 311 to rotate.

[0041] Specifically, the outer ring of the connecting ring on one side is designed with a hexagonal thread, which engages with the hexagonal through hole in the inner wall of the worm gear, thereby enabling the worm gear to rotate, driving the connecting ring to rotate, and in turn driving the swashplate to rotate. Of course, this is not the only structural design method; other types of threaded structures can also be applied to this solution.

[0042] Based on the structural design of this swashplate dynamic balancing assembly, during rotor rotation, the angle adjustment mechanism drives the swashplate to rotate, causing it to tilt at a certain angle to the rotor's rotating end face. As the rotor rotates, this causes the universal joint slide to move in a circular motion along the swashplate surface. Because the swashplate and the rotor's rotating end face are at a certain angle, as the rotor rotates, the distance between the universal joint ball seat and the rotor's rotating end face gradually decreases, and the elastic element is compressed accordingly. The reverse force of the elastic element, combined with its eccentric distance, provides a reverse torque, maintaining the dynamic balance of the rotor's rotation. Based on this structural design, the dynamic balance effect during rotor rotation can be adjusted by controlling the angle adjustment mechanism (i.e., adjusting the angle between the swashplate and the rotor's rotating end face).

[0043] Based on the structural design of the swashplate dynamic balancing component of the present invention, the swashplate dynamic balancing component can be further applied to the pitch adjustment component of the camera pan-tilt unit, which can realize dynamic balance during the pan-tilt adjustment process and is flexible and convenient to operate.

[0044] Specifically, in one possible implementation, the present invention further provides a continuously adjustable gimbal, which includes a gimbal base 24, the aforementioned swashplate dynamic balance adjustment assembly 100, and a pitch frame 25 that rotates around the stator shaft of the swashplate dynamic balance adjustment assembly 100. The swashplate dynamic balance adjustment assembly 100 is disposed above the gimbal base 24 and fixedly connected to the gimbal base 24.

[0045] The gimbal base and the swashplate dynamic balance adjustment assembly can be fixedly connected using various existing connection methods. For example, the gimbal base can be fixedly connected to the stator frame at the bottom of the swashplate dynamic balance adjustment assembly (specifically the sub-bottom end) by screws via a connecting plate with screw holes.

[0046] The specific structure and function of the swashplate dynamic balance adjustment component are detailed in the above embodiments and will not be repeated here.

[0047] In one possible implementation, the pitch mount 25 includes a support ring 252, a support plate 251, and a plate base 253 arranged opposite to each other. The plate base 253 is located on top of the support ring 252 and the support plate 251. The support plate 251 is fixedly connected to the rotor of the swashplate dynamic balance adjustment assembly, thus constituting the pitch motion of the pan-tilt unit and supporting the camera / video recording equipment. To facilitate the coordinated operation of the plate base and the rotor, the surface of the plate base that abuts against the rotor is designed as a concave arc surface, which allows for better assembly with the rotor, resulting in a more compact overall structure and better cooperation between the components.

[0048] In one possible implementation, the stator 20 is provided with a notched coaxial ring sleeve 201 at one end near the support plate 251, and a first damping adjustment component 202 is provided inside the ring sleeve 201. The rotor 21 is provided with a first concentric ring groove 021 at one end near the support plate 251. The first damping adjustment component 202 includes a first movable concentric ring 022 and a first adjusting ring 023. The first movable concentric ring 022 has a protrusion adapted to the notch, and the outer contour of the protrusion is a coaxial cylindrical surface with an external thread. The first adjusting ring 023 has an internal thread and cooperates with the protrusion. The ring wall between the first movable concentric ring 022 and the first concentric ring groove 021 is filled with damping oil. The first movable concentric ring 022 is driven to insert into or move away from the first concentric ring groove 021 by the first adjusting ring 023 to realize the damping adjustment during the pitch adjustment process of the pitch frame 25.

[0049] In this design, the first concentric ring groove and the first movable concentric ring are alternately positioned, meaning they are interlocking rings. The wall of the first movable concentric ring can move towards the first concentric ring groove and insert into its groove wall. Simultaneously, the surfaces of the groove walls of both concentric rings are coated with viscous damping oil. The first movable concentric ring is driven to move left and right by a first adjusting ring with internal threads. When the first movable concentric ring moves towards the first concentric ring groove, its wall gradually inserts into the groove wall, increasing the contact area and thus enhancing the damping effect of the oil. Conversely, when the first adjusting ring drives the first movable concentric ring away from the groove, disengaging it, the contact area decreases, and the damping effect of the oil diminishes. This structural design enables stepless damping adjustment during the pitch adjustment process of the pitch mount. By utilizing the specific structural design between the first damping adjustment component and the gimbal assembly, the overall structural design is simplified while achieving stepless pitch damping adjustment.

[0050] In one possible implementation, a stator end cover 27 is provided between the support plate 251 and the stator 20. A locking knob ring 28 is provided on the support plate 251, and a screw 29 is connected inside the locking knob ring 28. The locking knob ring 28 drives the screw 29 to move closer to or away from the stator end cover 27, so as to lock or release the pitch frame.

[0051] In this invention, as a specific implementation and application, the locking knob has an internal thread, and the locking knob ring has an externally threaded screw. The screw and the screw hole are designed to prevent rotation.

[0052] Since the first movable concentric ring 022, the first adjusting ring groove 023, and the support plate 251 are all connected to the rotor as a whole, they can all rotate relative to the stator along with the rotor. The stator end cover is located between the support plate 251 and the first movable concentric ring 022. By driving the screw inward through the locking knob ring, the stator end cover can be squeezed, which increases the friction between the surfaces of the stator end cover 27 and the stator 20, thereby restricting the rotation of the first movable concentric ring 022, that is, limiting the relative rotation of the entire rotor, thus realizing the overall locking of the pitching frame.

[0053] In one possible implementation, a locking wrench 26 is provided at the bottom of the swashplate dynamic balance adjustment component 100, which is used to lock the rotation of the gimbal base 25.

[0054] Since the gimbal base can rotate relative to other components on it, the locking wrench only needs to be able to lock the gimbal base and the components connected to it (specifically, the stator) from rotating relative to each other. The specific implementation structure of the locking wrench is not specifically limited. Of course, for a clearer explanation of the technical solution of this invention, please refer to [link to relevant documentation]. Figure 9 This invention is illustrated by a specific locking wrench structure. As shown in the figure, the locking wrench 26 may include a wrench 261, a screw 262, and a trapezoidal wedge 263. The screw 262 is connected to the inner end of the wrench 261, and the other end of the screw 262 is connected to the long side face of the trapezoidal wedge 263. The short side face of the trapezoidal wedge 263 faces inward. By rotating the wrench, the screw moves inward, which in turn pushes the trapezoidal wedge 263 inward. As the cross-section of the trapezoidal wedge gradually widens, the contact area between the wedge and the stator above it, as well as the gimbal base below it, gradually increases, and the frictional force also gradually increases, thereby achieving the effect of friction locking. At this time, the gimbal base can no longer rotate relative to the stator.

[0055] In one possible implementation, the gimbal base includes a turntable 242 and a second damping adjustment component 241. The second damping adjustment component 241 is disposed below the turntable 242 and includes a second concentric ring 041, a second movable concentric ring 042, and a second adjusting ring 043. The ring wall of the second movable concentric ring 042 is inserted between the ring walls of the second concentric ring 041. The ring walls of the second movable concentric ring 042 and the second concentric ring 041 are filled with damping oil. The second adjusting ring 043 has an internal thread and is sleeved on the second movable concentric ring 042. The second movable concentric ring 042 is driven to move up and down by the second adjusting ring 043 to achieve damping adjustment during horizontal rotation.

[0056] By designing a second damping adjustment component, stepless damping adjustment can be achieved during the horizontal rotation of the gimbal base simply by rotating the second adjustment ring. Furthermore, the overall structure is compact, truly achieving a small size and multiple functions.

[0057] In one possible implementation, a washer 30 is provided between the gimbal base 24 and the swash plate dynamic balance adjustment component 100.

[0058] In one possible implementation, a sealing plate 31 is also provided on the outside of the support plate.

[0059] From the above detailed description of the continuously variable gimbal in conjunction with the accompanying drawings, it can be understood that the continuously variable gimbal utilizes a swashplate dynamic balance adjustment assembly. Through an angle adjustment mechanism, the swashplate is driven to rotate, thereby making the swashplate and the rotor's rotating end face form a certain angle. When the pitch mount is adjusting its pitch (i.e., the pitch rotor rotates), for example, when the rotor starts rotating from the lower equilibrium position (zero degrees), it drives the universal joint slide to make a circular motion along the surface of the swashplate. Since the swashplate and the rotor's rotating end face form a certain angle, the distance between the universal joint slide and the rotor end face gradually decreases, causing the elastic element to be compressed. Thus, under the reaction force of the elastic element, the eccentric distance of the elastic element provides a reverse torque. When the swashplate is parallel to the rotor's rotating end face (i.e., the angle is zero), the distance between the swashplate and the rotor end face is constant. Therefore, when the pitching frame (i.e., the pitching rotor) pitches, it will not compress the elastic element, and the reverse torque is zero. When the angle between the swashplate and the rotor's rotating end face reaches the limit +90 degrees, the compression difference of the elastic element reaches its maximum, the reverse torque reaches its maximum, and the dynamic balancing ability also reaches its maximum, so as to achieve adjustable dynamic balancing effect of the pitching rotor.

[0060] By further designing the second damping adjustment component, stepless damping adjustment in the horizontal rotation direction of the gimbal can be achieved. The structure is simple and the functions are diversified.

[0061] Furthermore, by designing a first damping adjustment component on one side of the pitch mount, stepless damping adjustment can be achieved during the pitch adjustment process simply by controlling the rotation of the adjustment ring, thereby ensuring the convenience and safety of the entire gimbal adjustment process.

[0062] The continuously adjustable gimbal design based on the present invention is a two-dimensional adjustable gimbal with dynamic balancing capability. Through the second damping adjustment component, continuous damping adjustment in the horizontal direction of the entire gimbal is achieved. Based on the first damping adjustment component, continuous damping adjustment in the pitch direction can be achieved. The pitch mount can be fixed at any position through the control of the first damping adjustment component, realizing continuous damping adjustment during the pitch adjustment process. When the pitch mount rotates, the swashplate can be adjusted to rotate, thereby pushing the piston to compress the elastic element, providing a reverse rotational torque, and achieving dynamic balance.
