Description

Technical Field

[0001] This utility model relates to the field of photographic auxiliary equipment technology, specifically to a gimbal sphere structure with damping and dynamic balance and a photographic kit. Background Technology

[0002] Traditional ball heads are popular among consumers due to their compact size and flexible rotation. 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 traditional ball head structure, it is difficult to use in the field of video shooting. The most prominent drawback of traditional ball heads is the lack of dynamic balance and necessary damping systems. Especially when moving the camera in the pitch direction, the ball head can only rotate slowly by the friction between the ball and the ball locking mechanism, resulting in a stiff feel and a lack of dynamic balance required for video shooting.

[0003] In summary, the key to ensuring compatibility of ball heads with video pan / tilt heads lies in addressing the lack of smooth damping and dynamic balance during tilting movements, a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a gimbal spherical structure with damping and dynamic balance, so that the traditional spherical gimbal has a smooth damping feel and dynamic balance when moving the camera in the pitch direction, so as to solve the technical problems described in the background art.

[0005] This utility model is achieved through the following technical solution:

[0006] A gimbal spherical structure with damping and dynamic balance includes a sphere and a support column integrally formed with the sphere. The sphere has a strip-shaped opening on its surface away from the support column. The opening extends into the sphere to form a groove. A damping disk with a torsion spring is installed in the groove. When the damping disk is restricted from circumferential rotation, and the sphere moves circumferentially relative to the damping disk, the deformation of the torsion spring generates a restoring torque to provide a restoring force for the sphere.

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

[0008] The two ends of the torsion spring are support legs A and support legs B, respectively. The sidewall of the groove is provided with guide grooves on the side facing the two support legs. The two guide grooves are spatially symmetrical, and the two support legs extend into the ends of the two guide grooves respectively.

[0009] When the damping disk is restricted from circumferential rotation, and the sphere moves circumferentially relative to the damping disk, one leg of the torsion spring remains stationary, while the other leg is offset unidirectionally by the push of the groove wall at the end of the guide groove. The torsion spring's torsional deformation generates a restoring torque, providing a reset force for the sphere.

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

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

[0012] Furthermore, the side of the damping disk is in close contact with the groove wall, and the surface of the damping disk is coated with damping material, forming a damping system with the groove wall;

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

[0014] Furthermore, a limiting groove is formed on the outer circumferential surface of the damping disk facing the opening, and a spherical limiting block for limiting the circumferential rotation of the damping disk is movably inserted in the limiting groove. 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 includes a dual panoramic ball head, the dual panoramic ball head employing a ball head structure with damping and dynamic balance as described above.

[0016] A photography kit includes a multi-functional gimbal, the multi-functional gimbal employing a gimbal spherical structure with damping and dynamic balance as described above.

[0017] A photography kit includes an inverted gimbal employing a damped and dynamically balanced spherical gimbal structure as described above.

[0018] The beneficial effects of this utility model are as follows:

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

[0020] On the other hand, when the sphere limiting block extends into the limiting groove, the damping disk is restricted from circumferential rotation. At this time, when the sphere moves along the arc of the groove (rotating in the pitch direction), the torsion spring torsional deformation generates a restoring torque to provide a reset force for the sphere, thereby maintaining dynamic balance during camera movement. At the same time, the side of the damping disk is in close contact with the groove wall of the sphere, and the outer surface of the damping disk is coated with damping material, forming a damping system with the inner wall of the groove. When the sphere rotates in the pitch direction and the torsion spring deforms and resets, the damping material provides a good and dense damping feel, making the image more stable during video camera movement.

[0021] 2. When the ball limiting block moves downward and disengages from the groove under the action of the driving mechanism (at this moment, it is in photography mode), the ball can rotate freely without being restricted by the limiting block, and the camera (gimbal ball) can take pictures at any angle.

[0022] In summary, this utility model provides a gimbal spherical structure with damping and dynamic balance, which enables traditional spherical gimbals to possess excellent damping feel and dynamic balance function. This removes the technical obstacles for traditional spherical gimbals to enter the video shooting field, allowing them to also be compatible with video shooting functions and opening up a completely new application area for the development of spherical gimbals.

[0042] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0043] In the description of this application, the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0044] Please see Figure 1 The present invention provides one embodiment, Example 1: A gimbal spherical structure with damping and dynamic balance, comprising a sphere 1 and a support column 2 integrally formed with the sphere 1. The end of the support column 2 away from the sphere 1 has a threaded hole interface for connecting to a gimbal clamp or a tripod. The spherical surface of the sphere 1 away from the support column 2 is provided with a strip-shaped opening 3. The opening 3 extends into the sphere 1 to form a groove 4. A damping disk 5 is installed in the groove 4. The center point of the damping disk 5, the center line of the support column 2, and the central axis of the sphere 1 coincide, wherein the center point of the damping disk 5 coincides with the center of the sphere 1.

[0045] The side of the damping disk 5 is in close contact with the groove wall of the groove 4. The surface of the damping disk 5 is coated with damping material, which together with the groove wall of the groove 4 forms a damping system. When the ball 1 rotates circumferentially relative to the damping disk 5, the damping system provides a smooth and dense damping feel, making the picture more stable when shooting video.

[0046] Please see Figures 1 to 5 The damping disc 5 has a mounting hole 7 at its center, in which a torsion spring 6 is installed. The two ends of the torsion spring 6 are support legs A61 and B62, respectively. The support legs A61 and B62 are initially parallel to each other. The sidewall of the groove 4 has guide grooves 8 on the side facing the two support legs. The guide grooves 8 are arc-shaped. The two guide grooves 8 are symmetrical on two mutually perpendicular vertical planes passing through the center of the sphere 1. The two support legs extend into the ends (lower ends) of the two guide grooves 8. The damping disc 5 has two fan-shaped grooves 9 on the side facing the guide grooves 8.

[0047] When the damping disk 5 is restricted from circumferential rotation, and the sphere 1 moves circumferentially relative to the damping disk 5, one leg of the torsion spring 6 is kept stationary under the action of the damping disk 5, while the other leg is offset in one direction under the push of the end wall of the guide groove 8. The torsion spring 6 generates a restoring torque through torsional deformation, providing a reset force for the sphere 1 to maintain the dynamic balance of the sphere during rotation, resulting in better stability.

[0048] Please see Figure 1 and Figure 6 The damping disk 5 has a limiting groove 10 on its outer circumferential surface facing the opening 3, and also includes a hemispherical base 13. The hemispherical base 13 is close to the groove 4, and a spherical limiting block 11 is slidably fitted in the hemispherical base 13. A driving mechanism 12 is connected to the spherical limiting block 11 to drive it 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 is driven by the driving mechanism 12, it passes through the groove 4 and extends... When the ball enters the limiting groove 10, it is in camera mode. The damping disc 5 is restricted to rotate circumferentially by the square ball limiting block 5, and the ball 1 is restricted to rotate horizontally. The ball 1 can only rotate in pitch (one-dimensional movement) along the arc direction of the groove 4. The ball 1 will not sway left and right in the vertical direction to meet the video shooting requirements (the purpose of restricting the horizontal rotation of the ball is: the horizontal rotation is handled by the panoramic gimbal above the gimbal, and the damping feel of the panoramic gimbal when moving the camera is better than the damping feel of the ball rotating horizontally).

[0049] Furthermore, when the sphere 1 moves circumferentially relative to the damping disk 5 in this state, the torsion spring 6 undergoes torsional deformation to generate a restoring torque, providing a restoring force for the sphere 1;

[0050] When the ball limiting block 11 moves downward and disengages from the groove 4, the ball 1 can rotate freely without restriction. At this time, it is in photography mode, and the camera (gimbal ball) can be adjusted to any desired angle for shooting.

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

[0052] When the switching rod 121 moves into the mounting groove 125, the push rod pin 124 presses against the upward-sloping wall of the inclined groove 123, thereby causing the ball limiting block 11 to move downward and disengage from the groove 4. Conversely, when the switching rod 121 moves out of the mounting groove 125, the push rod pin 124 presses against the downward-sloping wall of the inclined groove 123, thereby causing the ball limiting block 11 to move upward and extend into the limiting groove 10 through the groove 4.

[0053] Please see Figure 6 A spring 126 is installed between the inward end of the switching rod 121 and the wall of the mounting groove 125. When the outward end of the switching rod 121 is not under force, the switching rod 121 is automatically pushed outward under the force generated by the deformation of the spring 126, thereby driving the ball limiting block 11 to extend into the limiting groove 10 through the groove 4, thus restricting 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 be manually operated to push the switching rod 121 into the mounting groove 125, thereby causing the ball limiting block 11 to move downward and disengage from the groove 4, thus releasing the restriction on the movement direction of the ball 1.

[0055] Please see 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 to a knob 1273. By turning the knob 1273, the locking screw 1272 is rotated. The locking screw 1272 and the threaded sleeve 1271 engage in a threaded transmission, thereby controlling the locking screw 1272 to push the switching rod 121 into the mounting groove 125, and to move the ball limiting block 11 downward away from the groove 4, thus switching the gimbal to photography mode.

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

[0057] Please see Figure 8 In Embodiment Two, unlike Embodiment One, the horizontal cross-section of the spherical limiting block 11 is circular. When the spherical limiting block 11 passes through the groove 4 and extends into the limiting groove 10, it can restrict the circumferential rotation of the damping disk 5. In addition, the sphere 1 can not only pitch along the arc of the groove 4, but also rotate horizontally around the center line of the spherical limiting block 11 (two-dimensional movement). This mode can meet the needs of wildlife photography (birding, animal running) or video shooting. Furthermore, when the sphere 1 pitches in the groove 4, the torsion spring 6 is torsional deformed to generate a restoring torque, providing the force required for the sphere 1 to reset its pitch direction.

[0058] Please see Figures 9 to 11 A photography kit includes a dual panoramic ball head 14, wherein the dual panoramic ball head 14 adopts a ball head structure as described in Embodiment 1 or Embodiment 2, the dual panoramic ball head 14 includes a ball head base 15, the side of the ball head base 15 is provided with a threaded hole 16, the threaded sleeve 1271 is threadedly connected to the threaded hole 16, a ball sleeve 17 is fitted in the top opening 3 of the ball head base 15, and the ball 1 is rotatably installed in the ball sleeve 17.

[0059] The hemispherical base 13 is vertically slidably installed inside the gimbal base 15. A pusher 18 is rotatably installed in the gimbal base 15. The pusher 18 is located below the hemispherical base 13. The pusher 18 and the hemispherical base 13 are respectively integrally formed with inclined protrusions 19 on opposite sides. A toggle mechanism 20 is connected to the pusher 18. The toggle mechanism 20, the pusher 18 and the hemispherical base 13 cooperate to form the planar thrust device disclosed in CN119467982A.

[0060] By turning the actuating mechanism 20, the pusher 18 is rotated clockwise and counterclockwise. This allows the hemispherical base 13 to move upward and lock the sphere 1 for photography through the action of the inclined surfaces of the upper and lower protrusions 19. Alternatively, it can move 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 overlap, the distance between the gimbal base 15 and the pusher 18 is the smallest. When the pusher 18 rotates so that the two inclined surfaces are offset, the distance between the hemispherical base 13 and the pusher 18 increases. The pusher 18 pushes the hemispherical base 13 upward to lock the sphere 1. Its specific working principle is the same as that of the planar thrust device, and will not be elaborated further here.)

[0061] When the gimbal switches from photography mode to video mode, first unlock the ball 1, then reset the ball 1 according to the scale markings on the outside of the ball 1, and finally operate the drive mechanism 12 to drive the ball limiting block 11 into the groove 10.

[0062] Please see Figure 12 and Figure 13 A photography kit includes a multi-functional gimbal 21, which employs a damped and dynamically balanced gimbal sphere structure as described above. The damped and dynamically balanced gimbal sphere structure can be mounted in the multi-functional gimbal 21 in a manner similar to that of the dual panoramic gimbal 14.

[0063] Please see Figure 13 and Figure 15 A photography kit includes an inverted gimbal 22, which employs a damped and dynamically balanced gimbal sphere structure as described above. The damped and dynamically balanced gimbal sphere structure can be mounted in the inverted gimbal 22 in a manner similar to that of the dual panoramic ball head 14.

[0064] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
