Description

Double-axis pivoting device of frame assembly for stabilizer, frame assembly and stabilizer

Technical Field

The present invention relates to the technical field of stabilizers, and in particular to a dual-axis pivot device of a frame assembly for a stabilizer. Further, the present invention also relates to a frame assembly using the dual-axis pivot device and a stabilizer with the frame assembly.

Background Art

It is known that the existing handheld stabilizer generally consists of a pan head that can fix the shooting device and a frame connected to the pan head at one end for supporting the pan head, wherein the frame is generally an upright rod-shaped structure that can be held by the shooter to hold the shooting unit during shooting. The frame with a slender rod-shaped structure has the following problems: in actual use, when shooting an object in a special position, for example, when the target is low, the stabilizer needs to be tilted downward, and when the target is high, the stabilizer needs to be tilted upward. In these two shooting situations, for a straight-bar handheld stabilizer, the tilt angle of the stabilizer with the shooting device is large, which is easy to cause discomfort to the wrist. During the shooting process that lasts for a long time, the wrist will quickly feel muscle fatigue and easily shake, thereby affecting the shooting effect. In addition, people who perform shooting activities with a large pitch tilt angle for a long time are also prone to damage to the wrist joints and muscles.

Therefore, there is still a demand in the industry to provide a stabilizer and a frame assembly thereof that is ergonomic, has variable operating postures, and has an adjustable tilt angle during use.

Summary of the invention

The present invention aims to provide a dual-axis pivoting device of a frame assembly for a stabilizer, a frame assembly and a stabilizer which can at least partially solve the above-mentioned deficiencies of the prior art.

According to one aspect of the present invention, a dual-axis pivot device of a frame assembly for a stabilizer is provided, the dual-axis pivot device being used to pivotally connect a first component and a second component of the frame assembly, and characterized in that the dual-axis pivot device comprises: a first rotating shaft fixedly connected to the first component; a pivot seat, one end of which is rotatably supported on the first rotating shaft to pivot around a first rotating axis relative to the first component; a pivot body fixedly connected to the second component, wherein the pivot body is pivotally supported at an opposite end of the pivot seat around a second rotating axis, and wherein the second rotating axis is orthogonal to the first rotating axis.

Thus, compared with the prior art, by providing the dual-axis pivot device according to the present invention, the design of the frame of the existing stabilizer is changed from the fundamental functional principle, and the existing single straight rod frame is modified into a frame assembly composed of multiple components extending upward in different operating postures. Thus, by providing the dual-axis pivot device according to the present invention, a high-quality stabilizer with excellent design characteristics and multiple operating postures can be provided, which greatly improves the ergonomic friendliness and user experience.

In a preferred embodiment, the pivot seat includes: a first accommodation portion located at one end thereof for accommodating the first rotating shaft, wherein the first accommodation portion is provided with a bearing portion for rotatably supporting the first rotating shaft; a second accommodation portion located at the opposite end thereof for accommodating the pivot body; and a base, wherein the base is provided with a pair of connecting arms at the opposite ends, wherein an internal space is defined between the pair of connecting arms; wherein the first accommodation portion is a countersunk hole located at one end of the pivot seat, and the second accommodation portion is the internal space located between the pair of connecting arms. Thus, by providing the pivot seat with an accommodation portion for inserting the first rotating shaft and the second rotating shaft, the first rotating shaft and the pivot body can be accommodated in a concealed manner, thereby preventing the dual-axis pivot device from having exposed moving parts, thereby improving the aesthetics and texture of the stabilizer.

In a preferred embodiment, the first component is a frame of a frame assembly, and the frame is connected to the pivot seat in a pivotable manner about the first rotation axis via a connecting plate fixedly connected to the first rotation axis. Thus, the connection between the two-axis pivot device and the frame assembly of the stabilizer is achieved in a simple and reliable manner.

In a preferred embodiment, a first component limiting mechanism is further included, which is configured to limit the pivoting angle range of the pivot seat relative to the first component around the first rotation axis, and includes: a limiting groove disposed in the counterbore and extending along the circumference of the first rotation axis on the pivot seat; and a stopper fixedly connected to the end of the first rotation axis, the stopper having a stopper protrusion extending into the limiting groove. Thus, the pivoting angle range of the pivot seat relative to the first component is limited in a simple and reliable manner.

In a preferred embodiment, it further includes a first component locking mechanism, which is configured to lock the pivot seat at a predetermined angular position relative to the first component, and includes: a clamping block arranged around the first rotation axis and capable of moving between a clamping position and a loosening position, wherein when the clamping block is in the clamping position, the clamping block prevents the pivot seat from rotating around the first rotation axis relative to the first component via frictional engagement and/or shape fit between the clamping block and the first rotation axis; and a threaded member, wherein the threaded member is configured to drive the clamping block to move between the clamping position and the loosening position via its own rotation. Thus, the setting of the angle between the first component and the pivot seat is achieved in a simple and reliable manner.

In a preferred embodiment, the second component is a handle bar with a connecting ring, and the pivot body is a ball joint or a rotating shaft arranged in and connected to the connecting ring, wherein the connecting ring and the pivot body are clamped in the second receiving portion so that the handle bar is pivotable relative to the pivot seat around the second rotation axis. Thus, the handle bar is prevented from having an undesirable interference with the pivot seat during the pivoting process, and the stable operation of the dual-axis pivot device is ensured.

In a preferred embodiment, a second component limiting mechanism is further included, which is configured to limit the pivot angle range of the second component relative to the pivot seat around the second rotation axis, and includes: a limiting groove defined by the pivot body or the connecting ring, the limiting groove being configured to rotate with the second component and limit the pivot angle range of the second component; and a stopper fixedly disposed on the pivot seat, the stopper extending into the limiting groove to prevent the second component from rotating beyond the pivot angle range via the stopper. Thus, the pivot angle range of the second component relative to the pivot seat is limited in a simple and reliable manner.

In a preferred embodiment, the pivoting body is a ball joint fixedly connected to the second component via a plurality of fasteners, wherein the limiting groove is surrounded by the outer periphery of the ball joint and two of the fasteners, and a support pin inserted into the limiting groove and serving as the stopper is provided between the pair of connecting arms, wherein the support pin is configured to prevent the second component from rotating beyond the pivot angle range. Thus, the pivot angle range of the second component relative to the pivot seat is defined in a more stable and reliable manner.

In a preferred embodiment, two adjacent fasteners among the plurality of fasteners are spaced apart at the same angle along the periphery of the ball joint, wherein the two fasteners are used to cooperate with the periphery of the ball joint to enclose the limiting groove to limit the pivot angle range.

In a preferred embodiment, the pivoting body is a shaft with a shoulder on one side, wherein the shaft is fixedly connected to the second component via the shoulder, the shoulder defines the limiting groove along at least part of the outer circumference of the shaft, and at least one connecting arm is provided with a limiting protrusion extending into the limiting groove and serving as the stopper, wherein the limiting protrusion prevents the second component from rotating beyond the pivoting angle range. Thus, the pivoting angle range of the second component relative to the pivot seat is defined in a simple and reliable manner.

In a preferred embodiment, a second component locking mechanism is further included, which is configured to lock the second component at a predetermined angular position relative to the pivot seat, and includes: a locking member, which is configured to move between a clamping position and a release position along the second rotation axis direction, wherein the locking member is configured to lock the second component at a predetermined angular position relative to the pivot seat in a frictional engagement and/or form-fitting manner when in the clamping position; and an adjusting member, which is configured to drive the locking member to move between the clamping position and the release position via its own rotation. Thus, locking the second component at a predetermined angular position relative to the pivot seat is achieved in a simple and reliable manner.

In a preferred embodiment, the locking member comprises a pair of clamping seats respectively arranged on both sides of the ball joint along the second rotation axis direction, wherein the pair of clamping seats have a spherical concave surface conforming to the outer spherical surface of the ball joint so as to stop the ball joint in a frictional engagement and/or form-fitting manner when the clamping seats are pressed. Thus, the second component is locked at a predetermined angular position relative to the pivot seat in a more stable and reliable manner by increasing the contact area.

In a preferred embodiment, at least one of the pair of clamping seats is configured to be expandable when compressed. Thus, the contact area between the ball joint and the clamping seat is increased in a simple and reliable manner.

In a preferred embodiment, the locking member includes a locking block located on one side of the rotating shaft in the direction of the second rotation axis, and the locking block is conformed to a recess provided at the end side of the rotating shaft to stop the rotating shaft in a frictional engagement and/or form-fitting manner when the locking block is pressed. Thus, locking the second component at a predetermined angular position relative to the pivot seat is achieved in a simple and reliable manner.

In a preferred embodiment, the adjusting member includes a threaded member that matches the threaded hole on the pivot seat, one end of the threaded member is fixedly connected to a torque wrench disposed outside the pivot seat, and the other end of the threaded member is connected to the locking member. Thus, it is convenient for the user to apply torque to the locking mechanism of the second component, thereby achieving more convenient and faster adjustment and locking.

In a preferred embodiment, the second component locking mechanism further comprises: a guide sleeve fixedly connected to the pivot seat; a wedge block slidable in the guide sleeve, the wedge block being arranged between the adjusting member and the locking member and being configured to wedge the locking member at its pressed position in a manner of forming a wedge surface fit with the locking member when pressed. Thus, due to the wedge surface fit and compression to prevent rebound, the second component is locked at a predetermined angular position relative to the pivot seat in a more stable and reliable manner.

In a preferred embodiment, the wedge block has a first concave-convex matching structure, and the locking member has a second concave-convex matching structure that matches the first concave-convex matching structure, so that the wedge block cannot rotate relative to the locking member. In this way, effective wedge surface matching and compression are ensured in a simple and reliable manner to prevent rebound.

In a preferred embodiment, at least one of the pivoting body, the locking member and the wedge block is at least partially made of a material selected from the following group: nylon, aluminum alloy, steel and polyoxymethylene resin. Thus, the locking mechanism can work more stably and reliably through material selection and pairing.

Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

In conjunction with FIG. 1 , a stabilizer 101 of an embodiment of a rack assembly 100 of the present invention is shown. The stabilizer 101 includes a gimbal 102 for fixing a shooting device such as a SLR camera, a video camera, a mobile phone, or a VR camera. As shown in FIG. 1 , the gimbal 102 shown therein is a three-axis gimbal, including three rotating shaft structures, namely a pitch axis structure, a roll axis structure, and a pan axis structure. The pitch axis structure can be used to install the shooting device. As an example, the shooting device can be driven to perform a pitch motion around the pitch axis by a motor in the pitch axis structure; the pitch axis structure is installed on the roll axis structure, and the shooting device is driven to perform a roll motion around the roll axis by a motor in the roll axis structure; the roll axis structure is installed on the pan axis structure, and the rotation of the shooting device camera around the pan axis is controlled by a motor in the pan axis structure. It should be noted that although a three-axis gimbal is shown in the figure, the solution provided in the embodiment of the present invention is also applicable to a two-axis gimbal.

Further, as shown in FIG1 , the stabilizer further includes a frame assembly 100 for supporting the gimbal 102. The frame assembly 100 includes: a first frame portion 1 extending in the direction of the pan axis of the gimbal 102, the first frame portion 1 being generally cylindrical as an example, wherein the first frame portion supports the gimbal 102 at one end thereof. It is understood that the first frame portion 1 is made of engineering plastic or metal with a certain strength. In order to facilitate the user's holding, the outer peripheral surface of the first frame portion 1 may be frosted, for example, to prevent the first frame portion 1 from accidentally slipping out of the user's hand.

As shown in FIG1 , the frame assembly 100 further includes a second component 2 extending laterally from the first frame portion 1, and the second component may also be referred to as the second frame portion of the frame assembly. The second component 2 has one end connected to the first frame portion and the other end away from the first frame portion 1. As shown in FIG1 , as a preferred example, the first frame portion 1 and the first frame portion 2 may be constructed as an integral part, which may be produced by molding when the first frame portion 1 and the second frame portion 2 are made of plastic. It will be appreciated by those skilled in the art that when the first frame portion 1 and the second frame portion 2 are formed in an integral part, the number of parts and components in manufacturing the stabilizer or the frame assembly may be reduced and the assembly cost may be reduced accordingly. Of course, it will be appreciated by those skilled in the art that the first frame portion 1 and the second frame portion 2 may also be independent components connected to each other.

As an example, the cross-section of the second frame part 2 is generally a rectangular cylindrical structure with an axis A1, which is rounded at both ends. Preferably, the second frame part 2 is a cylindrical structure that is axially symmetrical about its own axis A2. The width of the second frame part 2 is roughly the same as the diameter of the first frame part 1 to allow it to be connected to the first frame part 1 in a roughly smooth transition manner, which avoids the existence of a sudden change or step on the outer surface of the frame assembly 100, so that the frame assembly 100 has a good grip feel or product texture. Preferably, the second frame part 2 is provided with soft rubber on the upper and lower end surfaces of its cylindrical structure for increasing the friction between the user's hand and the user's hand when the user holds it. As an alternative, a texture that increases friction can also be formed on the outer peripheral surface of the second frame part 2.

As a non-limiting example, the second frame portion 2 is configured as a battery compartment of the stabilizer 101 for accommodating batteries. The battery compartment can be designed to allow the user to open it from the outside to replace the battery, or it can be designed to prohibit the user from opening it and only charge the accommodated battery with the charging interface. Of course, those skilled in the art will understand that the second frame portion can also be configured to be used for other purposes such as arranging function buttons. It is understandable that the second frame portion 2 can be made of the same material as the first frame portion 1, such as but not limited to plastic or metal.

As shown in FIG. 1 , the frame assembly 100 further includes a second component 3 that can be arranged at an angle with the second frame part 2, and the second component can also be called a gripping rod. The gripping rod 3 has a connection end connected to the second frame part 2 and a gripping end that is away from the second frame part 2 and is shown in FIG. 1 as being located above the connection end. Specifically, as shown in FIG. 1 , the gripping rod 3 can be constructed as a cylindrical structure that extends upward from the connection end and has a generally circular cross-section. The gripping end of the gripping rod 3 is preferably provided with an arc surface that fits the shape of the user's hand surface to increase the contact surface between the gripping rod 3 and the user's hand surface. Further preferably, at least one operating member of the stabilizer 101 is provided along its outer peripheral surface at the gripping end 32, and the operating member can be, for example, a button, a dial or a finger pressure switch. Through such an arrangement, the user is allowed to operate the operating member of the stabilizer 101 with an idle finger when holding the stabilizer at the gripping end 32, thereby improving the user experience when the user uses it.

Further, as shown in FIG1 , the handle bar 3 according to the present invention can be connected to the end of the second frame part 2 in a pivotable manner around the first rotation axis A1 of the second frame part 2 via a dual-axis pivot device 4 disposed between the handle bar 3 and the second frame part 2, thereby allowing the user to adjust the angle of the handle bar 3 relative to the first frame part 1, thereby allowing the user to flexibly adjust the form of the frame assembly according to the actual application environment to ensure that the stabilizer is operated in an ergonomic manner. Further, the dual-axis pivot device 4 also allows the handle bar 3 to pivot relative to the second frame part 2 around a second rotation axis A2 orthogonal to the first rotation axis A1 to adjust the angle between the handle bar 3 and the second frame part 2.

FIG2 shows an example of the dual-axis pivot device 4. The dual-axis pivot device 4 is used to dual-axis pivotally connect the second frame part 2 as the first component and the handle bar 3 as the second component of the frame assembly 100. As shown in FIG2, the dual-axis pivot device 4 includes: a connecting plate 41 fixedly connected to the first component; wherein the connecting plate 41 is provided with a plurality of through holes for fasteners to pass through, so that the connecting plate is fixedly connected to the first component of the frame assembly 100 via the fasteners arranged in the holes. A first rotating shaft 42 fixedly connected to the connecting plate 41, wherein the first rotating shaft 42 is supported on the connecting plate 41 in an integrally formed manner, and of course the first rotating shaft 42 can also be supported on the connecting plate 41 by, for example, bonding or welding and rotated therewith. It is also understandable that the connecting plate 41 can be omitted, that is, the first rotating shaft 42 can be directly fixedly connected to the first component. The dual-axis pivot device 4 also includes a pivot seat 43, wherein one end of the pivot seat 43 is rotatably supported on the first rotation axis 42 so as to pivot relative to the first component with the first rotation axis as the rotation center axis A1. Further, it also includes a pivot body 44 fixedly connected to the handle bar 3 as the second component, and in this embodiment, the pivot body is configured as a rotation axis. The pivot body 44 is pivotally supported on the other end of the pivot seat 43 around a second rotation axis A2, wherein the second rotation axis A2 is orthogonal to the first rotation axis A1.

Further, as shown in FIG. 2 , the pivot seat 43 includes: a first accommodation portion 431 located at one end thereof for accommodating the first rotating shaft 42, wherein a bearing portion (not shown) for rotatably supporting the first rotating shaft 42 is disposed in the accommodation portion; and a second accommodation portion 432 located at the other end thereof for accommodating the pivot body 44; and a base portion 433, wherein the base portion 433 is provided at the other end thereof with a pair of connecting arms 434, wherein an internal space 435 is defined between the pair of connecting arms; in this embodiment, the first accommodation portion is a countersunk hole located at one end of the base portion 433, and the second accommodation portion is an internal space 435 located between the pair of connecting arms 434. Through the first accommodation portion and the second accommodation portion, the pivot seat 43 is made possible to pivot around the first rotating axis A1 via the first rotating shaft 42 and the second component 3 is made possible to pivot around the second rotating axis A2 via the pivot body 44.

As shown in FIG. 2 , one end of the second component (i.e., the handle bar 3) is provided with a fixedly connected connecting ring 31, wherein the handle bar 3 is accommodated in an internal space 435 between a pair of connecting arms 434 in a manner of being fixedly sleeved on the pivot body 44 via the connecting ring 31. The clamping action of the pair of connecting arms 434 on the connecting ring 31 can prevent the connecting ring 31 and the pivot body 44 from undesired movement in the direction of the second rotation axis A2, thereby allowing the handle bar 3 to pivot only around the second rotation axis A2 relative to the pivot seat 43. In this embodiment, the above-mentioned pivot seat 43 is, for example, integrally formed by injection molding, and then the first rotating shaft 42 and the pivot body 44 are respectively inserted into the pivot seat 43 to realize the dual-axis pivoting function. Thus, the adjustment of the operating posture of the frame assembly is achieved in a simple and reliable manner.

In order to limit the pivot angle range of the holding rod 3 relative to the pivot seat around the second rotation axis A2, preferably, the dual-axis pivot device 4 also includes a second component limiting mechanism for limiting the pivot angle range of the second component (i.e., the holding rod 3) relative to the pivot seat 43, wherein as shown in FIG2 , the second component limiting mechanism includes: a shoulder 51 provided at the end of the pivot body 44, wherein the shoulder 51 extends on a portion of the outer periphery of the pivot body to define a limiting groove 52. As a preferred example, a plurality of threaded holes are provided on the shoulder 51, thereby the holding rod 3 can be fixedly connected to the rotating shaft of the pivot body 44 by passing a fastener such as a screw through the threaded hole and a corresponding threaded hole provided on the connecting ring 31. As an example, the limiting groove 52 is formed by the shoulder 51 not extending along the entire periphery of the pivot body, wherein the angle range of the central angle corresponding to the limiting groove 52 corresponds to the pivot angle range of the second component relative to the pivot seat 43, that is, the two side walls of the limiting groove 52 are formed as stop end walls when the pivot body 44 rotates around the second rotation axis A2. Of course, it is feasible to form a shoulder on the entire periphery of the entire pivot body 44, and then use machining to make the desired limiting groove 52. Further, the second component limiting mechanism also includes a limiting protrusion 53 as a stopper provided on the pivot seat corresponding to the limiting groove, wherein the limiting protrusion extends into the limiting groove 52 defined by the shoulder 51. The limiting protrusion 53 is, for example but not limited to, a cylinder extending into the limiting groove 52, so that the holding rod 3 is prevented from rotating beyond its pivot angle range through the cooperation between the cylinder and the stop end walls at both ends of the limiting groove 52, thereby limiting the pivot angle range of the second component relative to the pivot seat 43. As a non-limiting angle range, in this embodiment, the holding rod 3 pivots within an angle range of about 120 degrees relative to the pivot seat 43. Furthermore, the holding rod 3 pivots within an angle range of about 90 degrees relative to the pivot seat 43.

In a more advantageous aspect, in order to keep the handle bar 3 at an angular position relative to the pivot seat 43 adjusted by the user, the dual-axis pivot device 4 of the present application also includes a second component locking mechanism for locking the handle bar 3 (i.e., the second component) at a predetermined angular position relative to the pivot seat 43, which includes: a recess 61 provided at the end of the pivot body 44, wherein the recess 61 can be formed by machining an opening at one end of the pivot body 44, and of course, the recess 61 can also be formed integrally when the pivot body 44 is injection molded; and a second component locking mechanism relative to the recess 61 along the second component locking mechanism. A locking block 62 that moves between the clamping position and the releasing position in the direction of the rotation axis A2, as shown in FIG2, wherein the locking block 62 is generally truncated cone-shaped and its outer contour is sized to form frictional engagement and/or shape fit with the recess 61 when it is in the locking position, thereby locking the pivoting of the second component 3 relative to the pivot seat 43 through the frictional engagement and/or shape fit between the locking block 62 and the recess 61 of the pivot body 44; and an adjusting member 63, which is configured to make the locking block 62 move between the clamping position and the releasing position through its own rotation. For frictional engagement and/or shape fit, it can be achieved by selecting the friction coefficient of the material pair of the locking block 62 and the recess 61 or by providing a corresponding shape fit structure on the locking block 62 and the recess 61, which are all known to those skilled in the art and will not be repeated here.

As shown in FIG. 2 , the adjusting member is a threaded member that matches with the threaded hole on the pivot seat 43, wherein one end of the threaded member is fixedly connected with a torque wrench 64 disposed outside the pivot seat 43, and the other end thereof is connected to the locking block 63. When in use, the user drives the adjusting member 63 to rotate via the torque wrench 64 disposed outside the pivot seat 43, and when the adjusting member 63 rotates, the adjusting member 63 is reciprocated linearly moved in the axial direction of the second rotation axis A2 via the threaded cooperation between the adjusting member 63 and the threaded portion (not shown) in the pivot seat 43, thereby causing the locking block 62 to move between its locking position and its loosening position.

Further preferably, in order to prevent the pair of connecting arms 434 in the pivot seat 43 from expanding outward due to their own stress during use, thereby affecting the normal pivoting of the pivot body 44 and the frictional engagement between the locking block 62 and the notch 61, a support pin 9 connected between the pair of connecting arms 434 is provided to prevent the pair of connecting arms 434 from expanding outward, wherein the support pin 9 can be, for example, a connecting column that is screwed into the pair of connecting arms 434. In the case where the support pin 9 is provided, the holding rod 3 is provided with a groove for avoiding the support pin 9, so that the holding rod 3 does not interfere with the support pin 9 within the pivoting angle range of the holding rod 3. Further, the support pin 9 can also be provided on the limiting protrusion 53 of the pivot seat 3, which can enable the support pin 9 to be directly accommodated in the inner hollow part of the connecting ring 31, so that the support pin 9 can be prevented from interfering with the holding rod 3 within the pivoting angle range of the holding rod 3 without the need for additional slotting.

Furthermore, in order to prevent the influence of external dust and moisture on the pivot body 44, when the pivot body 44 is inserted and located in the pivot seat 43, it also includes a cover 10 for sealing from the outside the hole and the second accommodation portion on the connecting arm 434 for the pivot body to be inserted when assembling the dual-axis pivot device, wherein the cover 10 is, for example, a cover with a clamping foot, wherein the clamping foot is engaged with a clamping groove provided in the connecting arm 434 of the pivot seat 43, thereby being fixedly connected to the pivot seat 43. Preferably, a sealing ring is provided on the cover 10 to improve the sealing performance against the influence of the external environment.

In order to limit the pivoting angle range of the pivot seat 43 relative to the frame part as the first component 2, preferably, the dual-axis pivot device 4 also includes a first component limiting mechanism for limiting the pivoting angle range of the pivot seat relative to the first component, wherein the first component limiting mechanism includes: a limiting groove extending along the circumferential direction of the first rotating shaft 42 and arranged in the aforementioned counterbore of the pivot seat 43; and a stopper 71 fixedly sleeved at the end of the first rotating shaft 42, wherein the stopper 71 is, for example, a collar that matches the shape of the first rotating shaft 42 and rotates synchronously with the first rotating shaft 42, wherein the stopper 71 has a stopper protrusion 72 extending into the limit groove. Thus, the pivoting angle range of the pivot seat 43 relative to the first component 2 is limited by the limiting action between the stopper protrusion 72 and the two end walls of the limit groove. As a non-limiting angle range, in this embodiment, the pivot seat 43 pivots within an angle range of 180 degrees relative to the first component 2. Furthermore, the pivot seat 43 pivots relative to the first component 2 within an angular range of 120 degrees.

In a more favorable aspect, in order to enable the pivot seat 43 to remain at an angular position relative to the first component 2 adjusted by the user, a first component locking mechanism for setting the angle between the first component 2 and the pivot seat 43 is also included, wherein the first component locking mechanism includes: a clamping block 81 arranged around the first rotating shaft 42 and capable of moving between a clamping position and a release position, as shown in Figure 2, the clamping block 81 is, for example, a dovetail-shaped structure with an open end, which is partially arranged around the first rotating shaft 42, so that it can move between a release position and a clamping position under the action of an external force. Specifically, when the clamping block 81 is in the loosened position, the clamping block 81 is stretched outward under the action of its own tensioning force so as not to have frictional engagement with the first rotating shaft 42, which allows the pivot seat 43 to freely rotate relative to the first component 2; and when the clamping block 81 is in the clamped position under the action of external force to overcome its own tensioning force, the clamping block 81 prevents the pivot seat 43 from rotating relative to the first component 2 around the first rotating shaft through frictional engagement with the first rotating shaft 42, thereby setting the angular position of the first component 2 and the pivot seat 43. Further, the mechanism for applying external force can be, for example, a threaded member 82, wherein the threaded member 82 can be matched with a threaded hole provided on the pivot seat 43, wherein one end of the threaded member 82 is fixedly connected to a knob 83 provided on the outside of the pivot seat 43 for user operation, and the other end of the threaded member 82 abuts against the clamping block 81. Thus, by operating the knob, the user can selectively apply external force to the clamping block 81 so that it moves between the clamping position and the loosening position, which ultimately achieves the goal of keeping the pivot seat 43 at the angular position relative to the first component 2 adjusted by the user.

Further, another example of the dual-axis pivot device 4 is shown in FIG3 . The dual-axis pivot device 4 is also used to dual-axis pivotally connect the second frame portion as the first component of the frame assembly 100 and the handle bar 3 'as the second component. As shown in FIG2 , the dual-axis pivot device 4 includes: a connecting plate 41 'fixedly connected to the first component. A first rotating shaft 42 'fixedly connected to the connecting plate 41 ', wherein the first rotating shaft 42 is supported on the connecting plate 41 in an integrally formed manner, for example. It is also understandable that the connecting plate 41 'can be omitted, that is, the first rotating shaft 42 'can be directly fixedly connected to the first component. The dual-axis pivot device 4 also includes a pivot seat 43 ', wherein one end of the pivot seat 43 'is rotatably supported on the first rotating shaft 42 'so as to pivot relative to the first component with the first rotating shaft as the rotation center axis A1. Furthermore, it also includes a pivot body 44' fixedly connected to the handle bar 3 as the second component. In the present embodiment, the pivot body is constructed as a ball joint 44' as shown in FIG3. The ball joint 44' is pivotally supported on the other end of the pivot seat 43 around a second rotation axis A2, wherein the second rotation axis A2 is orthogonal to the first rotation axis A1. In the present embodiment, the ball joint 44' can be a complete sphere, or a spherical segment with a spherical surface partially, as long as it can form a spherical contact with the corresponding clamping seat (described in detail below). Preferably, the ball joint 44' is at least partially made of a material selected from the following group: nylon, aluminum alloy, steel and polyoxymethylene resin (POM).

Further, as shown in FIG3 , the pivot seat 43′ comprises: a first receiving portion 431′ located at one end thereof for receiving the first rotating shaft 42′, wherein the first receiving portion 431′ is provided with a bearing portion (not shown) for rotatably supporting the first rotating shaft 42′; and a second receiving portion located at the other end thereof for receiving the ball joint 44′; and a base 433′, wherein the base 433′ is provided with a pair of connecting arms 434′ at the other end thereof, wherein an internal space 435′ is defined between the pair of connecting arms; in this embodiment, the first receiving portion is a countersunk hole located at one end of the base 433, and the second receiving portion is an internal space 435′ located between the pair of connecting arms 434. Through the first receiving portion and the second receiving portion, the pivot seat 43′ is made possible to pivot around the first rotating axis A1 via the first rotating shaft 42′ and the second component 3′ is made possible to pivot around the second rotating axis A2 via the ball joint 44′.

As shown in FIG3 , one end of the second component (i.e., the handle bar 3′) is provided with a fixedly connected connecting ring 31′, wherein the handle bar 3′ is accommodated in the internal space 435 between a pair of connecting arms 434 in a manner of being fixedly sleeved on the ball joint 44′ via the connecting ring 31′. The clamping action of the pair of connecting arms 434′ on the connecting ring 31′ can prevent the connecting ring 31′ and the ball joint 44′ from undesired movement in the direction of the second rotation axis A2, thereby allowing the handle bar 3′ to pivot only around the second rotation axis A2 relative to the pivot seat 43′. In this embodiment, the pivot seat 43′ is integrally formed, for example, by injection molding, and then the first rotating shaft 42′ and the ball joint 44′ are respectively inserted into the pivot seat 43′ to realize the dual-axis pivoting function. Thus, the adjustment of the operating posture of the frame assembly is achieved in a simple and reliable manner.

In this embodiment, as a non-limiting example, when assembling the dual-axis pivot device 4, the connecting ring 31' is first inserted into the internal space 435' between the pair of connecting arms as the second accommodation portion, and then the ball joint 44' is placed in the connecting ring 31' located in the internal space 435' from one side along the second rotation axis A2. A plurality of threaded holes are provided on the outer periphery of the ball joint 44', preferably but not limited to three threaded holes evenly spaced at an angle of 120 degrees. Accordingly, the same number of threaded holes are provided along the outer periphery of the connecting ring 31' corresponding to the above-mentioned threaded holes (as shown in Figure 3), so that the connecting ring 31' is fixedly connected to the ball joint 44' by fasteners such as screws that are inserted into the connecting ring 31' and the ball joint 44', thereby allowing the handle bar 3' to be able to pivot around the second rotation axis A2 relative to the pivot seat 43' via the ball joint 44'.

In order to limit the pivot angle range of the handle bar 3' relative to the pivot seat around the second rotation axis A2, preferably, the dual-axis pivot device 4 also includes a second component limiting mechanism for limiting the pivot angle range of the second component (i.e., the handle bar 3') relative to the pivot seat 43', wherein as shown in FIG3, the second component limiting mechanism includes: a limiting groove defined by the above-mentioned multiple fasteners and the outer periphery of the ball joint 44'. Specifically, preferably but not limited to, when three fasteners are evenly spaced at an angle of 120 degrees on the outer periphery of the ball joint 44', the limiting groove within an angle range of 120 degrees can be defined by two of the fasteners and the outer periphery of the ball joint. As a variation, three protrusions for fasteners to penetrate can also be evenly spaced at an angle of 120 degrees on the outer periphery of the connecting ring 31', so that the limiting groove within an angle range of 120 degrees can be defined by two of the protrusions and the outer periphery of the ball joint. Those skilled in the art will know that the pivot angle range corresponding to the limit slot can be adjusted by adjusting the angle between the two fasteners or the protrusions through which the fasteners are inserted. Furthermore, the second component limit mechanism also includes a support pin 9' fixedly disposed at the opposite end of the pivot seat 43' as a stopper, and the support pin 9' is fixedly disposed in the limit slot relative to the pivot seat 43', so that the support pin 9' can prevent the handle bar 3' from rotating beyond the above-mentioned pivot angle range. It should be pointed out that the pivoting of the handle bar 3' within an angle range of about 120 degrees relative to the pivot seat 43' is only an exemplary angle range. In the present embodiment, it is also conceivable that the handle bar 3' is pivoted within an angle range of about 90 degrees relative to the pivot seat 43'.

In a more favorable aspect, in order to enable the holding rod 3’ to be maintained at the angular position relative to the pivot seat 43’ adjusted by the user, the dual-axis pivot device 4 of the present application also includes a second component locking mechanism for locking the holding rod 3’ at a predetermined angular position relative to the pivot seat 43’, as shown in Figure 3, which includes: a pair of clamping seats 661 and 662 as locking members respectively arranged on both sides of the ball joint 44’ along the second rotation axis A2 direction, wherein the pair of clamping seats 661 and 662 are configured to move between a clamping position and a released position along the second rotation axis A2 direction shown in the figure, and when the locking member is in the clamping position, the holding rod 3’ is locked at a predetermined angular position relative to the pivot seat 43’ in a frictionally engaged/shape-fitting manner. Specifically, the pair of clamping seats 661 and 662 have spherical concave surfaces conforming to the outer spherical surface of the ball joint 44' to stop the ball joint 44' in a frictional engagement/form fit manner when the pair of clamping seats 661 and 662 are pressed. The frictional engagement/form fit manner has been described above and will not be repeated here. Further, the second component locking mechanism also includes an adjusting member configured to drive the locking member to move between the pressing position and the releasing position through its own rotation.

Preferably, one of the pair of clamping seats 661 and 662 is configured to be expandable when pressed. Specifically, this can be achieved by making the clamping seat 662 have an open periphery, that is, the clamping seat 662 has an opening. Since the clamping seat 662 is expandable, when the ball joint 44' presses the clamping seat 662, the clamping seat 662 can further expand to accommodate the ball joint 44' with a larger contact area, which can better lock the ball joint 44' to prevent the handle bar 3' from deviating from the predetermined angle position when an unexpected external action occurs.

As shown in Fig. 3, the adjusting member includes a threaded member 63' that matches with the threaded hole on the pivot seat 43', wherein one end of the threaded member is fixedly connected to a torque wrench 64' disposed outside the pivot seat 43', and the other end thereof is connected to the locking member. When in use, the user drives the threaded member 63' to rotate via the torque wrench 64' disposed outside the pivot seat 43'. When the threaded member 63' rotates, the threaded member 63' is threadedly matched with the threaded hole (not shown) in the pivot seat 43' to achieve reciprocating linear motion in the axial direction of the second rotation axis A2, thereby causing the locking member to move between its compression position and release position.

Further preferably, the second component locking mechanism shown in FIG. 3 further includes: a guide sleeve 65 connected to the pivot seat 43' via a fastener and a wedge block 663 slidable in the guide sleeve 65, wherein one end of the wedge block 663 is connected to the threaded member 63' as an adjusting member, and the other end thereof is pressed against the clamping seat 661 as a locking member in a wedge-face matching manner, so that when the threaded member 63' is axially guided and moves inward in the guide sleeve 65 in the axial direction of the second rotation axis A2, the threaded member 63' presses the wedge block 663, and then the wedge block 663 presses the clamping seat 661. Due to the wedge-face matching between the wedge block 663 and the clamping seat 661, the clamping seat 661 can be wedged in its pressed position without being prone to rebound. When the clamping seat 661 is pressed by the wedge block 663, the ball joint 44' is locked in a frictional engagement/form fit manner via the spherical concave surfaces of the clamping seats 661 and 662, thereby locking the handle bar 3' relative to the pivot seat 43' at a predetermined angle. Further, as described above, when pressed, the clamping seat 662 is expandable, so that a larger contact area can be used to accommodate the ball joint 44', which can better lock the ball joint 44' to prevent the handle bar 3' from deviating from the predetermined angle position when an unexpected external action occurs.

More preferably, as shown in FIG3 , there is a concave-convex matching structure 67 between the wedge block 663 and the clamping seat 661, which is composed of a first concave-convex matching structure and a second concave-convex matching structure that matches the first concave-convex matching structure. The concave-convex matching structure 67 is configured so that the wedge block 663 cannot rotate relative to the clamping seat 661. As an example, as shown in FIG3 , the second concave-convex matching structure on the clamping seat 663 is a convex strip protruding from the inclined surface of the clamping seat 661 that forms the wedge surface matching, and the first concave-convex matching structure on the wedge block 663 is a groove that matches the first concave-convex matching structure on the inclined surface of the wedge block 663. Therefore, the wedge block 663 and the clamping seat 661 cannot rotate relative to each other, thereby ensuring that the wedge surface matching will not be misaligned or misaligned due to the rotation of the wedge block 663. As a result, it is ensured that the second component locking mechanism can more stably and reliably lock the second component at a predetermined angle relative to the pivot seat.

It should be noted that, in the embodiment shown in FIG3 , it is preferred that at least one of the ball joint 44 ′, the pair of clamping seats 661 and 662, and the wedge block 663 is at least partially made of a material selected from the following group: nylon, aluminum alloy, steel, and polyoxymethylene resin (POM). Thus, through such material selection and pairing, the friction coefficient on the contact surface between the ball joint 44 ′, the pair of clamping seats 661 and 662, and the wedge block 663 is increased, so that the locking mechanism works more stably and reliably.

More preferably, in order to prevent the influence of external dust and moisture on the ball joint 44', when the ball joint 44' is inserted and positioned in the pivot seat 43', a cover 10' for sealing from the outside is further included, wherein the cover 10' is, for example, a cover with a clamping foot, wherein the clamping foot is engaged with a clamping groove provided in the connecting arm 434' of the pivot seat 43', thereby being fixedly connected to the pivot seat 43'. Preferably, a sealing ring is provided on the cover 10' to improve the sealing performance against the influence of the external environment.

In order to limit the pivoting angle range of the pivot seat 43' relative to the frame part as the first component, preferably, the dual-axis pivot device 4 also includes a first component limiting mechanism for limiting the pivoting angle range of the pivot seat relative to the first component, wherein the first component limiting mechanism includes: a limiting groove extending along the circumferential direction of the first rotating shaft 42' arranged in the counterbore of the pivot seat 43'; and a stopper 71' fixedly sleeved at the end of the first rotating shaft 42', wherein the stopper 71' is, for example, a collar that matches the shape of the first rotating shaft 42' and rotates synchronously with the first rotating shaft 42', wherein the stopper 71' has a stopper protrusion 72' extending into the limit groove. Thus, the pivoting angle range of the pivot seat 43' relative to the first component is limited by the limiting action between the stopper protrusion 72' and the two end walls of the limit groove. As a non-limiting angle range, in this embodiment, the pivot seat 43' pivots within an angle range of 180 degrees relative to the first component. Furthermore, the pivot seat 43' is pivotable relative to the first component within an angular range of 120 degrees.

In a more advantageous aspect, in order to enable the pivot seat 43' to remain at an angular position relative to the first component adjusted by the user, a first component locking mechanism for setting the angle between the first component and the pivot seat 43' is also included, wherein the first component locking mechanism includes: a clamping block 81' arranged around the first rotating shaft 42' and capable of moving between a clamped position and a released position, as shown in Figure 3, the clamping block 81' is, for example, a dovetail-shaped structure with one end open, which is partially arranged around the first rotating shaft 42', so that it can move between a released position and a clamped position under the action of an external force. Specifically, when the clamping block 81' is in the loosened position, the clamping block 81' is stretched outward under the action of its own tensioning force so as not to have frictional engagement with the first rotating shaft 42', which allows the pivot seat 43' to freely rotate relative to the first component; and when the clamping block 81' is in the clamped position under the action of external force to overcome its own tensioning force, the clamping block 81' is frictionally engaged with the first rotating shaft 42' and/or prevents the pivot seat 43' from rotating relative to the first component around the first rotating shaft, thereby setting the angular position of the first component and the pivot seat 43'. Further, the mechanism for applying external force can be, for example, a threaded member 82', wherein the threaded member 82' can be matched with a threaded hole provided on the pivot seat 43', wherein one end of the threaded member 82' is fixedly connected to a knob 83' provided on the outside of the pivot seat 43' for user operation, and the other end of the threaded member 82 abuts against the clamping block 81'. Thus, by operating the knob by the user, external force can be selectively applied to the clamping block 81, so that it moves between the clamping position and the loosening position, which ultimately achieves the goal of maintaining the pivot seat 43' at the angular position adjusted by the user relative to the first component.

It should be noted that, although the adjustment of the first component locking mechanism and the second component locking mechanism, etc., is described in the above text in the form of manual adjustment by the user, those skilled in the art will understand that manual adjustment is only an example, and the above functions can also be achieved by automatic adjustment and should therefore be considered to fall within the protection scope of the present invention.

The frame assembly with the double-axis pivoting device according to the present invention and the stable operation of the frame assembly will be described below with reference to FIG. 1 .

As mentioned above, in the prior art, in actual use, when shooting an object in a special position, for example, when the target is low, the stabilizer needs to be tilted downward, and when the target is high, the stabilizer needs to be tilted upward. In these two shooting situations, for a straight-stick handheld stabilizer, the tilt angle of the stabilizer with a shooting device is relatively large, which brings ergonomic discomfort.

As shown in Figure 1, the stabilizer according to the present invention, through the description of the above-mentioned multiple embodiments, transforms the existing straight rod-shaped frame into a multi-section frame assembly with a dual-axis pivot device according to the present invention, which allows the holding angle to be adjusted via the holding rod relative to the second frame part 2 in a manner that is pivotable around the second rotation axis A2, and allows the angle between the holding rod 3 and the first frame part 1 to be changed in a manner that is pivotable around the first rotation axis A1 relative to the first frame part 1, thereby achieving a change in the operating posture of the stabilizer and an adjustable holding angle during use, which greatly improves the ergonomics of the stabilizer and enhances the user experience.

Specifically, when a stabilizer with a multi-stage frame assembly with a dual-axis pivot device according to the present invention is used for low-position shooting, the stabilizer can be first placed flat so that the first frame part 1 is roughly parallel to the ground at a certain height, and the second frame part 2 is roughly vertically oriented and the handle bar 3 is roughly horizontally oriented. At this time, the user can carry the stabilizer by hand on the handle bar 3 (that is, hold the stabilizer in a manner that is roughly vertically aligned with the overall center of gravity of the stabilizer and the shooting device). After determining the appropriate position of the user's hand on the handle bar 3, the user can straighten his arm so that the arm, wrist and the overall center of gravity of the stabilizer and the shooting device are aligned. In this case, since there is basically no distance between the overall center of gravity of the stabilizer and the shooting device and the arm and wrist, the user can hold the stabilizer 101 in a labor-saving manner to shoot, which greatly improves the ergonomic friendliness of the stabilizer and improves the user experience of the user. At this time, the holding angle of the holding rod 3 can be adjusted relative to the second frame part 2 in a pivotable manner around the second rotation axis A2, so that the user can hold the stabilizer with the shooting device in the most comfortable and labor-saving position, which further improves the user experience.

Furthermore, when a stabilizer with a multi-stage frame assembly having a dual-axis pivot device according to the present invention is used for high-position shooting, the pivot seat and the handle bar can first be pivoted relative to the second frame part 2 to such an angle via the dual-axis pivot device: the handle bar is pivoted to a position substantially perpendicular to the first frame part 1. In such a posture, the user is allowed to support the stabilizer with the user's shoulder by holding the first frame part 1 and placing the second frame part and the handle bar on the user's shoulder. Therefore, it can be ensured that in the case of long-term high-position shooting, the user's shoulder is fully utilized to share the overall weight of the stabilizer with the shooting device, thereby greatly improving the ergonomic friendliness of the stabilizer and enhancing the user experience.

It should be pointed out that although the operating posture of the stabilizer in this article is explained above in terms of manual support by a user, it can be understood that the above-mentioned stabilizer can also be mounted on a machine such as a drone for support, which should also be regarded as part of the protection scope of the present invention.

Further, although the operations of the stabilizer of the multi-section frame assembly with the dual-axis pivot device according to the present invention in two postures of low-position shooting and high-position shooting are introduced above, those skilled in the art know that the operations in the above two postures are only given as examples, and the stabilizer according to the present invention can also be operated in other postures that can be achieved via the dual-axis pivot device, and is not limited to the two postures given as examples in the embodiment.

It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in the various embodiments may also be combined to form other implementation methods that can be understood by those skilled in the art.

The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Without departing from the concept and principle of the present invention, equivalent changes, modifications and combinations that can be made by those skilled in the art should all fall within the scope of protection of the present invention.
