[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] Ball heads are one of the more common types of gimbals, widely used for connecting and oriented cameras and camcorders. However, most current ball heads rotate in three dimensions, making it impossible to achieve stable spatial positioning control, especially in terms of damping during rotation. Summary of the Invention
[0004] Technical problems to be solved
[0005] The gimbal damping adjustment mechanism of this utility model utilizes the structure of the inner bushing itself in conjunction with the horizontal base and damping adjustment components to achieve an adjustable damping effect during the rotation of the gimbal, thus better meeting the needs of uniform and stable camera movement control in the photography and videography process.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a gimbal damping adjustment mechanism, comprising a horizontal base, an inner bushing, and a damping adjustment assembly. The inner bushing has a central shaft hole for coaxial rotation of the horizontal base's shaft. The damping adjustment assembly is disposed between the outer cylindrical surface of the inner bushing and the inner wall of the horizontal base. The damping adjustment assembly includes a slider and an adjusting element. The space between the inner side of the slider and the outer cylindrical surface of the inner bushing is filled with damping oil. By adjusting the slider's movement through the adjusting element, the gap between the inner side of the slider and the outer cylindrical surface of the inner bushing is sequentially changed, thereby achieving damping adjustment.
[0008] In one possible implementation, the adjusting element is an adjusting ring, and the slider is a plurality of sliders evenly distributed circumferentially. The damping magnitude is adjusted by rotating the adjusting ring to drive the sliders to move sequentially or in groups inward and outward.
[0009] In one possible implementation, the inner wall of the adjusting ring is provided with a plurality of recesses corresponding to the number of sliders, and protrusions are formed between adjacent recesses, so that when the adjusting ring rotates, the protrusions abut against the sliders, thereby causing the sliders to move inward.
[0010] In one possible implementation, the adjacent recesses have different lengths.
[0011] In one possible implementation, the slider is a coaxial arc surface slider, and the recessed portion corresponds one-to-one with the outer arc surface of the slider, so that when the recessed portion moves to the position of the outer arc surface, the slider resets.
[0012] In one possible implementation, an elastic element is provided between the slider and the bottom outer wall of the bushing to help the slider reset.
[0013] In one possible implementation, a positioning ball is provided on the outside of one of the sliders.
[0014] In one possible implementation, the adjusting element is an adjusting knob connected to the slider. The adjusting knob drives the slider to move, thereby adjusting the damping magnitude.
[0015] In one possible implementation, a positioning groove is formed on the inner wall of the horizontal base, and a rack that matches the positioning groove is provided on the outer side of the slider, so that the positioning effect is achieved by the rack and the positioning groove cooperating with each other.
[0016] In one possible implementation, an elastic element is also provided between the slider and the locking knob.
[0017] In one possible implementation, the inner bushing extends upward to connect to the bushing. The gimbal damping adjustment mechanism also includes a housing that encloses the bushing and has a first contraction slit. The first contraction slit is contracted or restored by a screw engaging an internal thread, thereby compressing or relaxing the bushing.
[0018] In one possible implementation, the housing is also provided with a damping memory knob.
[0019] In one possible implementation, a sealing ring is also provided between the bushing and the housing.
[0020] In one possible implementation, the bushing has a second shrinkage slit to provide shrinkable space.
[0021] In one possible implementation, a flexible dustproof component is provided inside the second contraction joint.
[0022] To solve the above-mentioned technical problems, the present invention further provides a gimbal, which includes the above-mentioned gimbal damping adjustment mechanism, and further includes a ball, a quick-release plate seat and a bushing. The inner bushing is connected upward to the bushing, and the bushing wraps around the ball to form a universal ball joint. The top of the ball is connected to the quick-release plate seat through the ball diameter.
[0023] In one possible implementation, the spherical gimbal further includes a horizontal orientation component, which includes a horizontal axis, a collar, and a positioning pin. The horizontal axis passes laterally through the sphere and engages with the collars at both ends to form a single unit with the collar, the horizontal axis, and the sphere. The collar has a positioning hole on its outer side. When the positioning pin is inserted into the positioning hole, the sphere is limited to rotating only around the horizontal axis, while the outer shell rotates synchronously along the longitudinal axis.
[0024] In one possible implementation, a piston is supported on the horizontal axis, a compression spring is fitted on the piston, the piston is placed in a central hole coaxial with the longitudinal axis of the sphere, and a compression knob is provided on the top of the compression spring.
[0025] (III) Beneficial Effects
[0026] Compared with the prior art, the present invention provides a gimbal damping adjustment mechanism and a gimbal, which has the following beneficial effects:
[0027] This gimbal damping adjustment mechanism includes a horizontal base, an inner bushing, and a damping adjustment assembly. The inner bushing has a central shaft hole for coaxial rotation of the horizontal base's shaft. The damping adjustment assembly is positioned between the outer cylindrical surface of the inner bushing and the inner wall of the horizontal base. The damping adjustment assembly includes a slider and an adjusting element. The space between the inner side of the slider and the outer cylindrical surface of the inner bushing is filled with damping oil. By adjusting the slider's movement using the adjusting element, the gap between the inner side of the slider and the outer cylindrical surface of the inner bushing is changed sequentially, thereby adjusting the damping magnitude. This damping adjustment mechanism allows for convenient adjustment of the gimbal's damping, better meeting the needs of uniform and stable camera movement control in photography and videography. When this adjustment mechanism is applied to a gimbal, the inner bushing extends upward to connect to a bushing. The bushing's own structure provides positioning and friction for the gimbal's ball, thus achieving integration with the horizontal base. Attached Figure Description

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0053] Example 1
[0054] Please see Figures 1-11 This is a structural schematic diagram of the gimbal damping adjustment mechanism and its components according to Embodiment 1 of this utility model. The gimbal damping adjustment mechanism 010 in Embodiment 1 includes a horizontal base 1, an inner bushing 24, and a damping adjustment component 3. The inner bushing 24 has a central shaft hole for coaxial rotation of the shaft of the horizontal base 1. The damping adjustment component 3 is disposed between the outer cylindrical surface of the inner bushing 24 and the inner wall of the horizontal base 1. The damping adjustment component 3 includes a slider 32 and an adjusting member 31. The space between the inner side of the slider 32 and the cylindrical surface of the inner bushing 24 is filled with damping oil. By adjusting the movement of the slider 32 through the adjusting member 31, the gap between the inner side of the slider 32 and the outer cylindrical surface of the inner bushing is changed sequentially, thereby achieving damping adjustment.
[0055] In this embodiment, the adjusting element 31 is an adjusting ring, and the slider 32 consists of multiple sliders evenly distributed around the circumference. The damping magnitude is adjusted by rotating the adjusting ring to drive the sliders to move sequentially or in groups inside and outside.
[0056] Please refer to Figure 4 As shown, the inner wall of the adjusting ring is provided with multiple recesses 311 corresponding to the number of sliders, and protrusions 312 are formed between adjacent recesses 311 so that when the adjusting ring rotates, the protrusions 312 abut against the sliders, causing the sliders to move inward. For ease of adjustment, the protrusions 312 are annular protrusions.
[0057] Because the inner side of the slider and the outer cylindrical surface of the inner bushing are filled with damping oil, the horizontal base is provided with fluid damping. When the gimbal rotates around the longitudinal axis based on the horizontal plane, the damping oil provides resistance and effectively plays a buffering role, achieving a slow and stable rotation effect.
[0058] In this embodiment, the damping is adjusted by adjusting the gap between the inner side of the slider and the outer cylindrical surface of the inner bushing using an adjusting ring. When the adjusting ring is rotated, the slider is pushed inward, thus the smaller the relative gap between it and the outer cylindrical surface of the inner bushing, the greater the damping, and vice versa.
[0059] In one possible implementation, slider 32 is a coaxial arc-shaped slider, with the recessed portion corresponding one-to-one with the outer arc surface of the slider, so that the slider resets when the recessed portion moves to the position of the outer arc surface. That is, when the outer arc surface of the slider just coincides with the recessed portion, the slider is in the released state. At this time, the gap between the slider and the outer cylindrical surface of the inner bushing is the largest, and it is in a zero-damping state.
[0060] In order to achieve different levels of damping adjustment, the lengths of adjacent recesses 311 are different in this embodiment.
[0061] See details Figure 4 As shown, this embodiment uses six sliders as an example for detailed explanation. Slider ① and slider ② are considered as a group. The recess 311 on the outer arc surface of slider ① is longer than the recess on slider ②. The other two groups of sliders have the same configuration. For further details, please refer to [link to relevant documentation]. Figure 7 As shown, Figure 7 When the adjusting ring is rotated, the three spaced-apart sliders (②, ④, ⑥) are squeezed inward and fully contact the outer cylindrical surface of the inner sleeve. However, the other three sliders (①, ③, ⑤) have relatively longer recesses on their outer arc surfaces. Therefore, when the adjusting ring is rotated, their outer arc surfaces remain aligned with the recesses and are not squeezed, thus preventing inward movement. This state can be understood as a 3x damping state.
[0062] When rotating the adjusting ring further, see... Figure 8As shown, as the outer arc surfaces of the three sliders (①, ③, ⑤) gradually detach from the recessed part, the protrusion of the adjusting ring presses against the outer arc surfaces of the sliders, causing the three sliders (①, ③, ⑤) to be further pressed inward. At this point, all six sliders are pressed inward and in complete contact with the outer cylindrical surface of the inner bushing, which is the state of maximum damping. This can be understood as a 6-times damping state.
[0063] When the adjusting ring is rotated further, as the recessed part of the adjusting ring moves back to the outer arc surface of the slider, it returns to the initial state (zero damping state), and so on.
[0064] Of course, based on actual usage needs, the damping can also be changed by adjusting the state of the rotary adjustment ring, that is, the damping can be changed from 6 times damping to 3 times damping, then to 0 damping, and so on. It should be noted that this embodiment is only used as an example with 6 sliders, but the number of sliders is not limited to this.
[0065] In one possible implementation, to help the slider reset when its outer arc surface coincides with the recessed part of the adjusting ring, an elastic element 33 is provided between the inner side of the slider 32 and the outer cylindrical surface of the inner bushing. In a specific implementation, the elastic element 33 can be a spring.
[0066] In one possible implementation, in order to achieve the positioning effect, a positioning ball 34 is provided on the outside of one of the sliders.
[0067] In one possible implementation, the inner bushing extends upward and is further connected to the horizontal base by passing through the bushing and the inner bushing 24 via the conical ring 4, thereby connecting the bushing, the inner bushing, and the horizontal base into one unit, so that the bushing and the horizontal base can rotate coaxially.
[0068] Please refer to the following: Figure 9 As shown, to facilitate the limiting of the slider, positioning parts 12 are provided circumferentially on the horizontal base 1, and each positioning part 12 is matched with the side of the slider. That is, the slider is locked between two positioning parts from the left and right directions by two adjacent positioning parts, and the positioning parts and the side of the slider are locked together by the interlocking parts.
[0069] For further details, please refer to [link / reference]. Figure 6 The inner bushing extends upward to connect to the bushing 2. The gimbal damping adjustment mechanism of this embodiment 1 further includes a housing 5, which wraps around the bushing 2. The housing 5 is provided with a first contraction slot 51. The first contraction slot 51 is retracted or restored by the screw 52 in conjunction with the internal thread at the other end, thereby achieving the compression or relaxation of the bushing 2.
[0070] The outer shell and bushing are provided with U-shaped slots 54 at corresponding positions. Through the U-shaped slots, the ball head can rotate with a range of ±90 degrees when rotating in the pitch angle.
[0071] In one possible implementation, a sealing ring 6 is provided between the bushing 2 and the outer shell 5 to achieve a tight fit between the bushing 2 and the outer shell 5.
[0072] In one possible implementation, the bushing 2 is further provided with a second contraction slit 22 to provide retractable space. One or more second contraction slits can be provided. By compressing the bushing with the inward contraction of the outer shell, the bushing, due to the retractable space, further tightens the sphere when the outer shell contracts, achieving a positioning and locking effect.
[0073] Furthermore, to prevent dust and sand accumulation within the second contraction joint 22, a flexible dustproof component 23 is installed inside the second contraction joint 22. This flexible dustproof component ensures the overall compactness and aesthetics of the product while not affecting the shrinkage of the bushing. For example, the flexible dustproof component can be made of materials such as rubber, foam rubber, or sponge.
[0074] In Example 1, different degrees of damping effect can be achieved by adjusting the rotation of the ring. The operation is simple and convenient. Furthermore, by utilizing the structure of the inner bushing itself, the connecting bushing extends upward. When used to connect the spherical gimbal, it can provide positioning and friction for the sphere, thereby achieving integration with the horizontal base. This not only achieves a slow and stable rotation effect during the horizontal rotation of the spherical gimbal, but also enables adjustable damping and quick locking.
[0075] Example 2
[0076] Please see Figures 12-16 This is a structural schematic diagram of the gimbal damping adjustment mechanism and its components according to Embodiment 2 of this utility model. The difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the adjusting component 31 is an adjusting knob, which is connected to a slider 32. The damping magnitude is adjusted by rotating the slider through the adjusting knob. The gimbal damping adjustment mechanism of Embodiment 2 will be described below with reference to the accompanying drawings.
[0077] In one embodiment, a gimbal damping adjustment mechanism 010 includes a horizontal base 1, an inner bushing 24, and a damping adjustment assembly 3. The inner bushing 24 is provided with a central shaft hole for the horizontal base 1 to rotate coaxially. A damping adjustment assembly is provided between the outer cylindrical surface of the inner bushing 24 and the inner wall of the horizontal base 1. The damping adjustment assembly 3 includes a slider 32 and an adjusting member 31. The space between the inner side of the slider 32 and the outer cylindrical surface of the inner bushing 24 is filled with damping oil. The slider 32 is moved by adjusting the adjusting member 31, thereby changing the gap between the inner side of the slider 32 and the outer cylindrical surface of the inner bushing 24, thereby realizing the adjustment of the damping magnitude.
[0078] The damping adjustment component of this utility model can be implemented using two different damping adjustment structures. In embodiment 2, the adjustment component 31 is an adjustment knob, which is connected to the slider 32. The slider 32 is moved by the adjustment knob to achieve the adjustment of the damping magnitude.
[0079] Specifically, in this embodiment, the inner surface of the slider 32 is set as an inclined surface, so that the slider can be driven inward by adjusting the knob to achieve a gradual change in damping. Since the inner surface of the slider is set as an inclined surface, and the outer surface of the inner bushing is also set as a cylindrical surface, the gap between the inclined surface and the outer cylindrical surface gradually decreases as the slider moves inward. That is, it provides a slow and gradual change in damping. When the inner surface of the slider 32 is in complete contact with the outer arc surface of the inner bushing, the damping reaches its maximum state, and the slider is driven outward in the opposite direction to achieve a slow and gradual decrease in damping.
[0080] By filling the space between the inner side of the slider and the outer cylindrical surface of the inner bushing with damping oil, fluid damping is provided for the horizontal base. When the gimbal rotates around the longitudinal axis based on the horizontal plane, the damping oil provides resistance, effectively buffering the rotation and achieving a slow and stable rotation effect.
[0081] In this embodiment, specifically, the inner bushing forms a central shaft hole, which is fixed to the central rotating shaft of the horizontal base 1, thereby achieving a connection and allowing the horizontal base and the inner bushing to rotate coaxially. A bushing extends upward from the inner bushing to connect to it, allowing the bushing to rotate relative to the horizontal base. This enables the gimbal connected to the bushing to rotate relative to the horizontal base, thereby achieving horizontal rotation adjustment of the gimbal.
[0082] In this application, the damping adjustment component adjusts the damping magnitude by regulating the gap between the slider and the outer cylindrical surface of the inner bushing. Rotating the knob moves the slider forward and backward; a smaller gap between the inner inclined surface of the slider and the outer cylindrical surface of the inner bushing results in greater damping, and vice versa. The specific method by which the knob moves the slider forward and backward is not specifically limited in this application, and existing related technologies can be used to assist in achieving this.
[0083] In one possible implementation, a positioning groove 11 is formed on the inner wall of the horizontal base 1, and a rack 321 adapted to the positioning groove 11 is provided on the outer side of the slider 32, so that the positioning effect is achieved by the rack 321 cooperating with the positioning groove 11.
[0084] In one possible implementation, such as Figure 16As shown, an elastic element 33 is also provided between the slider 32 and the locking knob 31. Specifically, it can be a spring. The elastic element provides a certain reverse force to the slider, thereby ensuring that the damping adjustment process has a buffering effect.
[0085] The inner bushing extends upwards to connect with the bushing. This bushing, acting as a connector for the gimbal, serves as a structural component of the ball head when connected. It both encloses the ball, providing positioning and good friction to ensure smooth rotation. The inner bushing extends downwards to engage with the horizontal base, creating a unified upper and lower structure. This allows the bushing's rotation to drive the horizontal rotation of the enclosed ball head. Furthermore, the inner bushing, in conjunction with the horizontal base and damping adjustment components, achieves a slow and stable horizontal rotation of the ball head, while also enabling adjustable damping and quick locking.
[0086] In one possible implementation, such as Figure 12 As shown, the inner bushing 24 extends upward to connect to the bushing. The gimbal damping adjustment mechanism further includes a housing 5, which encloses the bushing 2. The housing 5 is provided with a first contraction slot 51. The first contraction slot 51 is retracted or restored by the screw 52 in conjunction with the internal thread at the other end, thereby achieving the compression or relaxation of the bushing 2.
[0087] The outer shell and bushing are provided with U-shaped slots 54 at corresponding positions. Through the U-shaped slots, the ball head can rotate with a range of ±90 degrees when rotating in the pitch angle.
[0088] In one possible implementation, the outer casing 5 is also equipped with a damping memory knob 53. When the ball head is adjusted to the appropriate tightness, the screw engages with the internal thread to retract the first contraction joint, and the damping memory knob follows suit, so that the same damping can be achieved when the same position is adjusted again.
[0089] In one possible implementation, a sealing ring 6 is provided between the bushing 2 and the outer shell 5 to achieve a tight fit between the bushing 2 and the outer shell 5.
[0090] In one possible implementation, the bushing 2 is further provided with a second contraction slit 22 to provide retractable space. One or more second contraction slits can be provided. By compressing the bushing with the inward contraction of the outer shell, the bushing, due to the retractable space, further tightens the sphere when the outer shell contracts, achieving a positioning and locking effect.
[0091] Furthermore, to prevent dust and sand accumulation within the second contraction joint 22, a flexible dustproof component 23 is installed inside the second contraction joint 22. This flexible dustproof component ensures the overall compactness and aesthetics of the product while not affecting the shrinkage of the bushing. For example, the flexible dustproof component can be made of materials such as rubber, foam rubber, or sponge.
[0092] The gimbal damping adjustment mechanism of this embodiment includes a horizontal base, an inner bushing, and a damping adjustment assembly. The inner bushing has a central shaft hole for coaxial rotation of the horizontal base. The damping adjustment assembly is positioned between the outer cylindrical surface of the inner bushing and the inner wall of the horizontal base. The damping adjustment assembly includes a slider and an adjusting element. The space between the inner side of the slider and the outer cylindrical surface of the inner bushing is filled with damping oil. By adjusting the slider's movement through the adjusting element, the gap between the inner side of the slider and the outer cylindrical surface of the inner bushing is changed sequentially, thereby adjusting the damping magnitude. This damping adjustment mechanism allows for convenient adjustment of the gimbal's damping magnitude, better meeting the requirements for uniform and stable camera movement control during photography and videography. When this adjustment mechanism is applied to a gimbal, the inner bushing extends upward to connect with a bushing. Utilizing the bushing's own structure, it provides positioning and friction for the gimbal, enabling smooth rotation of the gimbal. Furthermore, the inner bushing extends downward, becoming integrated with the horizontal base, and in conjunction with the damping adjustment assembly, achieving both a slow and stable horizontal rotation effect for the gimbal and an adjustable damping effect.
[0093] Based on the gimbal damping adjustment mechanism described above, this embodiment further provides a gimbal; please refer to [link / reference]. Figures 17-19 As shown, the gimbal includes the aforementioned gimbal damping adjustment mechanism 010, and further includes a ball 020, a quick-release plate seat 030, and a bushing 2. The inner bushing extends upward to connect with the bushing 2, and the bushing 2 wraps around the ball 020 to form a universal ball joint. The top of the ball 020 is connected to the quick-release plate seat 030 through the ball diameter.
[0094] In one possible implementation, the spherical gimbal also includes a horizontal orientation component 040, which includes a horizontal axis 41, a collar 42, and a positioning pin 43. The horizontal axis 41 passes laterally through the sphere 020 and is engaged with the collars 42 at both ends to form a single unit with the collars 42, the horizontal axis 41, and the sphere 020. The collar 42 has a positioning hole 421 on its outer side. When the positioning pin 43 is inserted into the positioning hole 421, the sphere 020 is limited to rotating only around the horizontal axis 41, while the outer shell 5 rotates synchronously along the longitudinal axis.
[0095] It should be noted that the horizontal axis 41 and one of the collars 42 can be integrally formed, or they can be separate from the two collars 42 for easy installation.
[0096] A horizontal axis is provided inside the sphere, and the axis between the two opposing collars passes through the center of the sphere. Positioning holes, concentric with the axis, are located on the outer sides of the collars. When a positioning pin on the outer shell is inserted into this hole, the sphere can only rotate around the axis (first dimension) or rotate around the longitudinal axis based on the horizontal base (second dimension). This achieves movement in both pitch and horizontal rotation dimensions for the spherical gimbal.
[0097] The bushing is designed to reduce direct frictional loss between the ball and the outer shell, increase the ball's rotational flexibility, and provide self-lubrication and cushioning during rotation. Furthermore, a flexible, wear-resistant ball bushing is preferred. When the locating pin is disengaged and no constraint is applied to the ball, it can rotate freely in three dimensions. The flexible bushing effectively prevents collisions and friction between the ball and the outer shell, providing a rotational cushioning effect. During the process of restricting and constraining the ball, the flexible bushing greatly reduces damage to the ball.
[0098] The positioning pin 43 can be moved forward and backward by a corresponding screw mechanism on the outer casing 5. This application does not limit the specific screw mechanism, as long as it can synchronously rotate and move the positioning pin forward and backward.
[0099] In one possible implementation, a piston 050 is supported on a horizontal axis 41, a compression spring 060 is fitted on the piston 050, the piston 060 is placed in a central hole coaxial with the longitudinal axis of the ball 020, and a compression knob 070 is provided on the top of the compression spring 060.
[0100] In order to adapt to the high-strength elastic effect of the piston, the compression spring 060 can adopt a double-layer compression spring combination to further improve the elastic range and stiffness of the piston.
[0101] When the ball rotates around the axis between the collars, the horizontal axis rotates relative to the ball, pushing the piston to move upward along the central hole, thereby compressing the compression spring and generating a reverse torque, thus forming a dynamic balance effect of the spherical gimbal and improving the dynamic balance performance of the spherical gimbal during rotation.
[0102] Furthermore, a compression knob is provided at the top of the compression spring. The compression degree of the compression spring is controlled by the compression knob, thereby changing the preload on the compression spring and thus changing the elastic force of the compression spring, so as to achieve dynamic balance and adjustability.
[0103] Additionally, it should be noted that the quick-release plate holder in this invention is mainly used for connecting recording equipment such as cameras and camcorders. This invention does not further limit the specific structural form of the quick-release plate holder. Existing conventional quick-release plate holder structures, as long as they can connect to the sphere, do not affect the realization of the specific effects of this invention.
[0104] The quick-release plate holder structure shown in the accompanying drawings of this utility model is only one specific implementation and is not intended to limit the scope. Furthermore, to facilitate the operation and control of the quick-release plate holder, an operating handle 080 is also provided on one side of the quick-release plate holder.
[0105] Based on the above detailed description of the gimbal damping adjustment mechanism and the gimbal itself, combined with the accompanying drawings, it can be understood that the gimbal damping adjustment mechanism includes a horizontal base, an inner bushing, and a damping adjustment assembly. The inner bushing has a central shaft hole for coaxial rotation of the horizontal base's shaft. The damping adjustment assembly is positioned between the outer cylindrical surface of the inner bushing and the inner wall of the horizontal base. The damping adjustment assembly includes a slider and an adjusting element. The space between the inner side of the slider and the outer cylindrical surface of the inner bushing is filled with damping oil. By adjusting the slider's movement using the adjusting element, the gap between the inner side of the slider and the outer cylindrical surface of the inner bushing is changed sequentially, thereby adjusting the damping magnitude. This damping adjustment mechanism allows for convenient adjustment of the gimbal's damping magnitude to adapt to different usage scenarios. When this adjustment mechanism is applied to the gimbal, the inner bushing extends upward to connect with the bushing. Utilizing the bushing's own structure, it provides positioning and friction for the gimbal, enabling smooth rotation of the gimbal. Furthermore, by extending downward through the inner bushing, it integrates with the horizontal base and works in conjunction with the damping adjustment component. This achieves a slow and stable rotation effect during the horizontal rotation of the gimbal, as well as adjustable damping and quick locking.
[0106] Furthermore, by utilizing the damping adjustment mechanism of the spherical gimbal, the rotation of the sphere around the longitudinal axis is restricted through the cooperation of the positioning pin and the positioning hole, and the sphere is quickly positioned by utilizing the retraction of the outer shell contraction seam. Therefore, the ball joint structure of this invention can not only satisfy the free rotation of the spherical gimbal in three dimensions, but also selectively restrict the rotation of the sphere in a certain dimension to adapt to different scenarios. Moreover, based on the damping adjustment mechanism, by utilizing and improving the structural characteristics of the bushing itself, a slow and stable horizontal rotation process of the spherical gimbal is achieved, and the damping is adjustable and can be quickly locked.
[0107] Furthermore, a piston mechanism within the sphere allows the gimbal to rotate around its horizontal axis, pushing the piston upwards along the central hole. This compresses the compression spring, generating a counter-torque and creating a dynamic balance effect, thus improving the gimbal's dynamic balance performance during rotation. The compression knob controls the spring's compression level, altering its preload and elasticity to achieve adjustable dynamic balance.
[0108] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
