Description

Technical Field

[0001] The invention relates to the technical field of photography auxiliary equipment, and in particular to a pan / tilt head spherical structure with damping and dynamic balance and a photography kit. Background Art

[0002] The traditional spherical gimbal is characterized by its small size and flexible rotation, and is deeply favored by consumers. With the rapid development of short videos in recent years, the demand for video gimbals has been increasing. However, due to the limitations of the structure of the traditional spherical gimbal, it is difficult to use the traditional spherical gimbal in the field of video shooting. The more prominent disadvantage of the traditional spherical gimbal is that it does not have dynamic balance and the necessary damping system. Especially when the spherical gimbal moves in the pitch direction, the spherical gimbal can only rotate slowly by the friction between the sphere and the sphere locking mechanism. The hand feel is relatively stiff when moving the lens, and it lacks the dynamic balance required for video shooting.

[0003] In summary, how to solve the problem that the traditional spherical head does not have a dense damping feel and dynamic balance when moving the lens in the pitch direction is the key to making the spherical head compatible with the video head, and is a problem that technical personnel in this field need to solve urgently. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a gimbal spherical structure with damping and dynamic balance, so that the traditional spherical gimbal has a dense damping feel and dynamic balance when moving the lens in the pitch direction, so as to solve the technical problems described in the background technology.

[0005] The present invention is achieved through the following technical solutions:

[0006] A gimbal spherical structure with damping and dynamic balance comprises a sphere and a support pillar integrally formed with the sphere, a strip opening is provided on the spherical surface of the sphere away from the support pillar, the opening extends into the sphere to form a groove, a damping disc with a torsion spring is installed in the groove, when the damping disc is restricted from circumferential rotation and the sphere moves in a circle relative to the damping disc, the torsion spring deforms to generate a restoring torque to provide a reset force for the sphere.

[0007] Furthermore, a mounting hole is provided at the center of the damping disc, and the torsion spring is installed in the mounting hole;

[0008] The two ends of the torsion spring are leg A and leg B respectively, and the side wall of the groove is provided with guide grooves on one side facing the two legs respectively, the two guide grooves are in a quadratic symmetric relationship in space, and the two legs extend into the ends of the two guide grooves respectively;

[0009] When the damping disc is restricted from circumferential rotation and the sphere moves circumferentially relative to the damping disc, one leg of the torsion spring remains stationary, and the other leg is unidirectionally deflected under the push of the groove wall at the end of the guide groove, and the torsion deformation of the torsion spring generates a restoring torque to provide a restoring force for the sphere.

[0010] Furthermore, two fan-shaped grooves are respectively formed on one side of the damping disc facing the guide groove;

[0011] When the groove wall at the end of the guide groove pushes one of the legs of the torsion spring to deflect, the fan-shaped groove provides the required space for the deflection of the torsion spring leg.

[0012] Furthermore, the side surface of the damping disc is tightly fitted with the groove wall of the groove, and the surface of the damping disc is coated with damping material, forming a damping system with the groove wall of the groove;

[0013] The center point of the damping disk, the center line of the support column and the center axis of the sphere coincide with each other, wherein the center point of the damping disk coincides with the center of the sphere.

[0014] Furthermore, a limiting groove is provided on the outer circumferential surface of the damping disc facing the opening, a spherical limiting block for limiting the circumferential rotation of the damping disc is movably inserted in the limiting groove, and a driving mechanism for driving the spherical limiting block to extend into or out of the limiting groove is connected to the spherical limiting block.

[0015] A photography kit comprises a double panoramic spherical head, wherein the double panoramic spherical head adopts the head spherical structure with damping and dynamic balance as described above.

[0016] A photography kit comprises a multifunctional pan head, wherein the multifunctional pan head adopts the pan head spherical structure with damping and dynamic balance as described above.

[0017] A photography kit comprises an inverted pan head, wherein the inverted pan head adopts the pan head spherical structure with damping and dynamic balance as described above.

[0018] The beneficial effects of the present invention are:

[0019] 1. When the ball limit block extends into the limit groove through the groove under the action of the driving mechanism (at this time, it is in the camera mode), on the one hand, the ball limit block limits the vertical freedom of the ball, and the ball can only pitch and rotate along the arc direction of the groove or horizontally rotate along the center point of the ball limit block, thereby avoiding left and right shaking of the picture during video shooting and meeting the needs of video shooting;

[0020] On the other hand, when the spherical limit block extends into the limit groove, the damping disc is restricted from circumferential rotation. At this time, when the sphere moves along the arc direction of the groove (rotates in the pitch direction), the torsion spring torsional deformation generates a restoring torque to provide a reset force for the sphere, thereby maintaining the dynamic balance during the camera movement process; at the same time, the side of the damping disc is tightly fitted with the groove wall of the spherical groove, and the outer surface of the damping disc is coated with damping material, which forms a damping system with the inner wall of the groove. When the sphere rotates in the pitch direction and the torsion spring is deformed and reset, the damping material provides a good and dense damping feel, and the picture is more stable during video camera movement.

[0021] 2. When the spherical limiting block moves downward and out of the groove under the action of the driving mechanism (at this moment it is in photography mode), the sphere can rotate freely without being restricted by the limiting block, and the camera (pan head sphere) can shoot at any angle.

[0022] To sum up, by inventing a gimbal spherical structure with damping and dynamic balance, the traditional spherical gimbal has a good damping feel and dynamic balance function, which clears the technical barriers for the traditional spherical gimbal to enter the video shooting field, and makes the traditional spherical gimbal compatible with the video shooting function, opening up a new application field for the development of spherical gimbals.

[0042] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0043] In the description of the present application, the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0044] See also Figure 1 , an implementation mode provided by the present invention, Example 1: a ball structure of a pan / tilt with damping and dynamic balance, comprising a sphere 1 and a pillar 2 integrally formed with the sphere 1, wherein the pillar 2 has a threaded hole interface at one end away from the sphere 1, for connecting with a pan / tilt clamp or a tripod, a strip opening 3 is provided on the spherical surface of the sphere 1 away from the pillar 2, the opening 3 extends into the sphere 1 to form a groove 4, a damping disc 5 is installed in the groove 4, the center point of the damping disc 5, the center line of the pillar 2, and the center axis of the sphere 1 coincide with each other, wherein the center point of the damping disc 5 coincides with the center of the sphere 1;

[0045] The side surface of the damping disc 5 fits tightly with the groove wall of the groove 4. The surface of the damping disc 5 is coated with damping material, and a damping system is formed with the groove wall of the groove 4. When the sphere 1 rotates circumferentially relative to the damping disc 5, the damping system provides a smooth and dense damping feel, and the picture is more stable when the video is shot.

[0046] See also Figures 1 to 5 A mounting hole 7 is provided at the center of the damping disc 5, a torsion spring 6 is installed in the mounting hole 7, two ends of the torsion spring 6 are respectively a leg A61 and a leg B62, the initial positions of the legs A61 and the legs B62 are parallel to each other, a guide groove 8 is provided on the side wall of the groove 4 facing the two legs, the guide groove 8 is arc-shaped as a whole, the two guide grooves 8 are in a quadratic symmetric relationship on two mutually perpendicular vertical planes passing through the center of the sphere 1, and the two legs extend into the ends (lower ends) of the two guide grooves 8, and two fan-shaped grooves 9 are provided on the side of the damping disc 5 facing the guide groove 8;

[0047] When the damping disc 5 is restricted from circumferential rotation and the sphere 1 moves circumferentially relative to the damping disc 5, one leg of the torsion spring 6 is restricted from moving and remaining stationary under the action of the damping disc 5, and the other leg is unidirectionally deflected under the push of the groove wall at the end of the guide groove 8. The torsion spring 6 torsional deforms to generate a restoring torque, providing a restoring force for the sphere 1 to maintain dynamic balance during the rotation of the sphere, and has better stability.

[0048] See also Figure 1 and Figure 6The damping disc 5 is provided with a limiting groove 10 on the outer circumferential surface facing the opening 3, and also includes a hemispherical base 13, the hemispherical base 13 is close to the groove 4, a spherical limiting block 11 is slidably mounted in the hemispherical base 13, and the spherical limiting block 11 is connected to a driving mechanism 12 for driving the spherical limiting block 11 to slide into or out of the limiting groove 10. In this embodiment, the horizontal cross-section of the spherical limiting block 11 is square. When the spherical limiting block 11 passes through the groove 4 and extends out under the action of the driving mechanism 12, When the ball 1 is inserted into the limiting groove 10, it is in the camera mode. The damping disc 5 is limited by the square ball limiting block 5 to rotate in the circumferential direction, and the ball 1 is limited to rotate horizontally. The ball 1 can only rotate in the pitch direction (one-dimensional movement) along the arc direction of the groove 4, and the ball 1 will not swing left and right in the vertical direction to meet the video shooting requirements (the purpose of limiting the horizontal rotation of the ball is: the horizontal rotation is handed over to the panoramic head above the pan / tilt head. The damping feel of the panoramic head when moving the lens is better than the damping feel of the horizontal rotation of the ball).

[0049] In this state, when the ball 1 moves circumferentially relative to the damping disc 5, the torsion spring 6 torsional deforms to generate a restoring torque, providing a restoring force for the ball 1;

[0050] When the spherical limiting block 11 moves downward and leaves the groove 4, the sphere 1 can rotate freely without restriction. This is the photography mode, and the camera (pan-tilt sphere) can be adjusted to any desired angle for shooting.

[0051] See also Figure 6 The hemispherical base 13 has a mounting groove 125, and the driving mechanism 12 includes a switching rod 121 slidably assembled in the mounting groove 125. A through groove 122 is provided on the horizontal rod body of the switching rod 121, and the ball stop block 11 is installed in the through groove 122. An inclined groove 123 is provided on the side of the ball stop block 11, and a push rod latch 124 is installed in the inclined groove 123. The push rod latch 124 is fixedly connected to the switching rod 121. A sliding groove for limiting the sliding direction of the ball stop block 11 is also vertically provided in the hemispherical base 13, and the ball stop block 11 can only move up and down along the sliding groove;

[0052] When the switch rod 121 moves into the installation groove 125, the push rod pin 124 squeezes the groove wall of the inclined groove 123 that is inclined upward, thereby pushing the ball limit block 11 to move downward and disengage from the groove 4. Conversely, when the switch rod 121 moves out of the installation groove 125, the push rod pin 124 squeezes the groove wall of the inclined groove 123 that is inclined downward, thereby pushing the ball limit block 11 to move upward and extend into the limit groove 10 through the groove 4.

[0053] See also Figure 6 A spring 126 is installed between the inner end of the switching rod 121 and the wall of the mounting groove 125. When the outer end of the switching rod 121 is not subjected to force, the switching rod 121 is automatically pushed outward under the force generated by the deformation of the spring 126, thereby driving the ball limit block 11 to extend into the limit groove 10 through the groove 4, thereby limiting the movement direction of the ball 1;

[0054] An operating component 127 is installed at the outward end of the switching rod 121. The operating component 127 can push the switching rod 121 to move into the installation groove 125 under manual operation, and then move the ball limit block 11 downward to disengage from the groove 4, thereby releasing the restriction on the movement direction of the ball 1.

[0055] See also Figure 6 and Figure 7 The operating component 127 includes a threaded sleeve 1271, in which a locking screw 1272 is threadedly connected, one end of the locking screw 1272 faces the switching rod 121, and the other end faces outward and is fixedly connected with a knob 1273. The locking screw 1272 is rotated by screwing the knob 1273, and the locking screw 1272 and the threaded sleeve 1271 are threadedly matched for transmission, so that the locking screw 1272 can be controlled to push the switching rod 121 to move into the mounting groove 125, and the spherical limit block 11 is pushed downward to disengage from the groove 4, so that the gimbal is switched to the photography mode;

[0056] When the knob 1273 is turned to control the locking screw 1272 to move outward from the mounting slot 125, the outward end of the switching rod 121 is not blocked by the locking screw 1272, and the switching rod 121 is automatically pushed outward under the force generated by the deformation of the spring 126, thereby pushing the ball limit block 11 to extend into the limit slot 10 through the groove 4, limiting the circumferential rotation of the damping disc 5 and limiting the movement direction of the sphere 1, thereby switching the gimbal to the camera mode.

[0057] See also Figure 8, Embodiment 2, which is different from Embodiment 1 in that: in this embodiment, the horizontal cross-section of the spherical limit block 11 is circular. When the spherical limit block 11 passes through the groove 4 and extends into the limit groove 10, on the one hand, the circumferential rotation of the damping disc 5 can be limited. On the other hand, in addition to being able to pitch and rotate along the arc direction of the groove 4, the sphere 1 can also rotate horizontally around the center line of the spherical limit block 11 (movement in two dimensions). This mode can meet the needs of outdoor ecological shooting (bird shooting, animal running) or video shooting, and when the sphere 1 pitches and rotates in the groove 4, the torsion spring 6 is twisted and deformed to generate a restoring torque to provide the sphere 1 with the force required for resetting in the pitch direction.

[0058] See also Figures 9 to 11 A photography kit includes a dual panoramic spherical head 14, wherein the dual panoramic spherical head 14 adopts the head ball structure as described in Example 1 or Example 2, and the dual panoramic spherical head 14 includes a head seat 15, a threaded hole 16 is opened on the side of the head seat 15, and the threaded sleeve 1271 is threadedly connected to the threaded hole 16, and a ball sleeve 17 is clamped in the top opening 3 of the head seat 15, and the ball 1 is rotatably installed in the ball sleeve 17.

[0059] The hemispherical base 13 is vertically slidably installed inside the pan-tilt seat 15, and a push-down member 18 is rotatably installed in the pan-tilt seat 15. The push-down member 18 is located below the hemispherical base 13, and the push-down member 18 and the opposite side of the hemispherical base 13 are respectively integrally formed with a convex block 19 with an inclined surface, and a toggle mechanism 20 is connected to the push-down member 18. The toggle mechanism 20, the push-down member 18 and the hemispherical base 13 cooperate to form a plane thrust device in the publication number CN119467982A;

[0060] By screwing the toggle mechanism 20, the push-down member 18 is rotated clockwise or counterclockwise, and then the hemispherical base 13 can be pushed upward by the action of the upper and lower inclined surfaces of the protrusions 19 to lock the sphere 1 for photography, or moved downward to unlock the sphere 1 to adjust the photography angle or switch the gimbal working mode (when the inclined surfaces of the upper and lower protrusions 19 coincide with each other, the distance between the gimbal seat 15 and the push-down member 18 is minimum. When the push-down member 18 rotates so that the two inclined surfaces are offset from each other, the distance between the hemispherical base 13 and the push-down member 18 increases, and the push-down member 18 pushes the hemispherical base 13 to move upward to lock the sphere 1. Its specific working principle is the same as that of the planar thrust device, which will not be elaborated here).

[0061] When the gimbal is switched from the photography mode to the video recording mode, the sphere 1 is first unlocked, and then the sphere 1 is reset according to the scale mark outside the sphere 1 , and finally the driving mechanism 12 is operated to drive the sphere limit block 11 to extend into the groove 10 .

[0062] See also Fig.12 and Fig.13 A photography kit includes a multifunctional pan-tilt head 21, which adopts the pan-tilt head spherical structure with damping and dynamic balance as described above. The pan-tilt head spherical structure with damping and dynamic balance can be installed in the multifunctional pan-tilt head 21 in a manner similar to the dual panoramic spherical pan-tilt head 14.

[0063] See also Fig.13 and Fig.15 A photography kit includes an inverted gimbal 22, wherein the inverted gimbal 22 adopts the gimbal spherical structure with damping and dynamic balance as described above, and the gimbal spherical structure with damping and dynamic balance can be installed in the inverted gimbal 22 in a manner similar to the dual panoramic spherical gimbal 14.

[0064] Finally, it should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention are within the scope of protection required by the present invention.
