Description

Technical Field

[0001] This invention relates to a segmented, one-button locking gimbal device. Background Technology

[0002] In photography and projection work, gimbals are often mounted on tripods to install external equipment such as cameras or projectors. To adjust the shooting or projection direction, gimbals are generally equipped with ball joints to achieve angle and position adjustments. A typical gimbal includes a base with an open spherical cavity inside. The ball joint's ball head rotates within this cavity, and the joint extends out through the cavity's opening. A threaded push rod is located on the side of the base, its end abutting against the ball head to lock it in place at the cavity's opening.

[0003] The above-described gimbal structure requires multiple steps when fixing external devices: first, tighten the external device onto the connecting rod; then, after oscillating the external device to its angular position, lock the ball head with the threaded push rod. This structure is not only inconvenient to use and operate, but also, because the ball head, as the driving component, moves towards the opening of the spherical cavity, only a local surface of the ball head in the direction of the push force of the threaded push rod presses against the edge of the opening of the spherical cavity, resulting in a small locking force. When the connecting rod is long, it may become unstable when supporting a large load on the external device, thus creating a reaction force on the ball head and causing it to rotate relative to the spherical cavity. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a segmented one-button locking gimbal device. This gimbal device can fix and connect external devices and lock the ball joint with only one button operation. It can also reliably lock the ball joint and stably support the external device. Moreover, it is very convenient to use, improving user experience and work efficiency.

[0005] A segmented one-button locking gimbal device according to an embodiment of the present invention includes: The system comprises: a base body with an open movable cavity; a ball head rotatably disposed within the movable cavity; a connecting rod connected at one end to the ball head, extending from the opening of the movable cavity, and the other end connected to a mounting base with a mounting stud for connecting an external device; a rotating sleeve movably sleeved on the outside of the base body and the mounting base, capable of rotating and moving up and down relative to the mounting base; a clamping member connected to the inside of the rotating sleeve via a threaded structure, capable of moving up and down relative to the rotating sleeve and the base body; and a torque transmission structure disposed between the rotating sleeve and the mounting base. When the rotating sleeve rotates in a first clockwise direction, the torque transmission structure drives the mounting stud on the mounting base to rotate together to connect the external device. As the rotating sleeve continues to rotate in the first clockwise direction, the rotating sleeve and the clamping member move in opposite directions, and the clamping member pushes the opening edge of the movable cavity to press against the surface of the ball head, with one end of the rotating sleeve pressing against the external device.

[0006] The segmented one-button locking gimbal device according to embodiments of the present invention has at least the following beneficial effects: When connecting to an external device, the above-mentioned gimbal device first rotates the rotating sleeve in the first clockwise direction and drives the mounting stud to tighten onto the external device through the torque transmission structure. When the rotating sleeve continues to rotate in the first clockwise direction, the locking force between the mounting stud and the external device is greater than the torque that the torque transmission structure can transmit. At this time, the rotating sleeve rotates relative to the mounting base, the clamping member, and the base. The rotating sleeve and the clamping member move in opposite directions through the threaded structure. One end of the rotating sleeve can be clamped onto the external device. At the same time, the clamping member pushes the opening edge of the movable cavity to clamp onto the surface of the ball head. Thus, the external device can be fixed, clamped, and the ball head locked with just one button operation, improving the convenience of use and providing a large locking force on the ball and the external device.

[0007] In some embodiments of the present invention, the torque transmission structure includes a compression spring, an abutment member, and a torque ring. The torque ring is disposed on the inner peripheral wall of the rotating sleeve. The outer peripheral wall of the mounting base is recessed with a telescopic groove. The abutment member reciprocates along the telescopic groove to extend or retract relative to the outer peripheral wall of the mounting base. The compression spring is located within the telescopic groove and drives the abutment member to spring against the inner peripheral wall of the torque ring. The force between the inner peripheral wall of the torque ring and the abutment member can drive the rotating sleeve and the mounting base to rotate together. When the rotating sleeve rotates relative to the mounting base, the abutment member moves up and down relative to the torque ring.

[0008] In some embodiments of the present invention, the inner peripheral wall of the torsion ring is recessed and formed with a plurality of snap-fit ​​grooves arranged circumferentially around its axial direction. The snap-fit ​​grooves extend along the height direction of the torsion ring. The compression spring drives the abutment to elastically snap into one of the snap-fit ​​grooves. When the torque applied to the rotating sleeve is greater than the maximum force between the abutment and the snap-fit ​​groove, the rotating sleeve rotates relative to the mounting base so that the abutment sequentially enters and exits each of the snap-fit ​​grooves and moves along the extension direction of the snap-fit ​​groove.

[0009] In some embodiments of the present invention, the abutment is a ball, the cross-section of the snap-fit ​​groove is a semi-circle with the opening facing the ball, the radial dimension of the inner peripheral wall of the snap-fit ​​groove matches the diameter of the ball, and all the snap-fit ​​grooves are connected in sequence to form a quincunx pattern.

[0010] In some embodiments of the present invention, adjacent snap-fit ​​slots are connected by a narrow arc surface, which matches the outer peripheral wall of the mounting base to guide the rotating sleeve and the mounting base to rotate relative to each other.

[0011] In some embodiments of the present invention, the rotating sleeve has an internal threaded hole, the clamping member includes a threaded post that mates with the internal threaded hole, a guide rod hole is provided through the middle of the threaded post along its length, the connecting rod is movably passed through the guide rod hole, and one end of the threaded post is provided with a pressing part that abuts the seat against the ball head.

[0012] In some embodiments of the present invention, the movable cavity has a first spherical concave surface adapted to the ball head, the seat has a spherical convex surface facing the pressing part, the pressing part has a second spherical concave surface cooperating with the spherical convex surface, and the centers of the spherical convex surface, the first spherical concave surface and the second spherical concave surface coincide.

[0013] In some embodiments of the present invention, the middle portion of the rotating sleeve is provided with an installation channel extending through it along its axial direction. The base, the clamping member, and the mounting seat are arranged sequentially along the length direction of the installation channel. When the rotating sleeve rotates relative to the clamping member to move the clamping member closer to the base, the end of the rotating sleeve closer to the mounting seat moves away from the clamping member so that the mounting seat is received within the installation channel.

[0014] In some embodiments of the present invention, the cross-sectional shape of the connecting rod and the cross-sectional shape of the guide rod hole are both non-circular. The two ends of the connecting rod are respectively provided with a first screw portion and a second screw portion. The mounting base is provided with a first threaded mounting hole that mates with the first screw portion. The ball head is provided with a second threaded mounting hole that mates with the second screw portion. The opening of the movable cavity is a frustum-shaped channel that gradually expands away from the ball head.

[0015] In some embodiments of the present invention, a pipe is also included. The seat includes a lower support fixedly disposed inside one end of the pipe and an upper support partially extending outside the pipe. The interior of both the lower support and the upper support has a spherical groove that matches the ball head. The spherical groove of the lower support and the spherical groove of the upper support define the movable cavity. The opening of the movable cavity passes through the portion of the upper support extending out of the pipe and faces the lower support.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] See Figures 1 to 3The segmented one-button locking gimbal device of this invention includes: a base 100, wherein the base 100 has an open movable cavity 101; a ball head 200, rotatably disposed within the movable cavity 101; a connecting rod 300, one end of which is connected to the ball head 200, the connecting rod 300 extending out from the opening of the movable cavity 101, and the other end of the connecting rod 300 connected to a mounting base 400, the mounting base 400 having a mounting stud 410 for connecting an external device; a rotating sleeve 500, movably sleeved on the outside of the base 100 and the mounting base 400, capable of rotating and lifting relative to the mounting base 400; and a clamping member 600, connected to the inside of the rotating sleeve 500 via a threaded structure, capable of relative... The rotating sleeve 500 and the base 100 move up and down; the torque transmission structure 700 is disposed between the rotating sleeve 500 and the mounting base 400; when the rotating sleeve 500 rotates around the first clockwise direction, the torque transmission structure 700 drives the mounting stud 410 on the mounting base 400 to rotate together to connect the external device; when the rotating sleeve 500 continues to rotate around the first clockwise direction, the rotating sleeve 500 and the clamping member 600 move in opposite directions; the clamping member 600 pushes the opening edge of the movable cavity 101 to press against the surface of the ball head 200; one end of the rotating sleeve 500 is pressed against the external device.

[0024] When connecting an external device, the above-mentioned gimbal device first rotates the rotating sleeve 500 around the first clockwise direction and drives the mounting stud 410 to tighten onto the external device through the torque transmission structure 700. That is, the torque transmission structure 700 provides a fixed torque to install the external device. When the rotating sleeve 500 continues to rotate around the first clockwise direction, the locking force between the mounting stud 410 and the external device is greater than the torque that the torque transmission structure 700 can transmit. At this time, the rotating sleeve 500 rotates relative to the mounting base 400, the clamping member 600 and the base 100. The rotating sleeve 500 and the clamping member 600 move in opposite directions through the threaded structure. One end of the rotating sleeve 500 can be clamped onto the external device. At the same time, the clamping member 600 pushes the opening edge of the movable cavity 101 to clamp onto the surface of the ball head 200. Thus, the external device can be fixed, clamped and locked with a single operation, improving the convenience of use, and the locking force on the ball and the external device is large.

[0025] It should be explained that "segmented one-click locking" means that by rotating only one part, the external device can be locked first, and then the ball head 200 can be locked.

[0026] See Figure 1 and Figure 3In some embodiments of the present invention, the torque transmission structure 700 includes a compression spring 710, an abutment member 720, and a torque ring 730. The torque ring 730 is disposed on the inner peripheral wall of the rotating sleeve 500. The outer peripheral wall of the mounting base 400 is recessed and has a telescopic groove. The abutment member 720 reciprocates along the telescopic groove to extend or retract relative to the outer peripheral wall of the mounting base 400. The compression spring 710 is located within the telescopic groove and drives the abutment member 720 to spring against the inner peripheral wall of the torque ring 730. The force between the inner peripheral wall of the torque ring 730 and the abutment member 720 can drive the rotating sleeve 500 and the mounting base 400 to rotate together. When the rotating sleeve 500 rotates relative to the mounting base 400, the abutment member 720 moves up and down relative to the torque ring 730. It should be noted that the rotation center lines of the rotating sleeve 500 and the mounting base 400 are coaxial. The compression spring 710 drives the abutment 720 to extend outward along the telescopic groove and abut against the inner peripheral wall of the torsion ring 730. The user can align the mounting hole on the external device with the mounting stud 410 and pre-tighten it by a certain angle. Then, the user can rotate the rotating sleeve 500 to utilize the friction or locking force between the torsion ring 730 and the abutment 720 to drive the mounting base 400 to rotate together. This allows the mounting stud 410 to be tightened onto the external device until the mounting stud 410 can no longer be tightened onto the external device. At this point, the rotating sleeve 500 can rotate relative to the mounting base 400. Simultaneously, the rotating sleeve 500 and the clamping member 600 move in opposite directions through the threaded structure. One end of the rotating sleeve 500 moves closer to the external device to clamp onto the external device, while the clamping member 600 moves closer to the base 100 to push the opening edge of the movable cavity 101 to clamp onto the surface of the ball head 200.

[0027] See Figure 3In some embodiments of the present invention, the inner peripheral wall of the torsion ring 730 is recessed and formed with a plurality of snap-fit ​​grooves 731 arranged circumferentially around its axial direction. The snap-fit ​​grooves 731 extend along the height direction of the torsion ring 730. The compression spring 710 drives the abutment 720 to elastically snap into one of the snap-fit ​​grooves 731. When the torque applied to the rotating sleeve 500 is greater than the maximum force between the abutment 720 and the snap-fit ​​groove 731, the rotating sleeve 500 rotates relative to the mounting base 400 so that the abutment 720 sequentially enters and exits each of the snap-fit ​​grooves 731 and moves along the extension direction of the snap-fit ​​groove 731. Understandably, under the push of the compression spring 710, the abutment 720 elastically engages in a locking groove 731. When the rotating sleeve 500 is rotated, the side wall of the locking groove 731 exerts a significant force driving the abutment 720 to rotate along with the torque ring 730. This helps prevent the rotating sleeve 500 from slipping relative to the mounting base 400 before the mounting stud 410 is tightened onto the external device. Furthermore, while achieving a large torque transmission, and ensuring that the locking force between the mounting stud 410 and the external device exceeds the maximum transmittable torque, the goal of rotating the rotating sleeve 500 relative to the mounting base 400 is also achieved. Moreover, the abutment 720, elastically engaged in the locking groove 731 under the action of the compression spring 710, provides an audible alert.

[0028] Furthermore, it should be noted that the maximum torque that the torque transmission structure 700 can transmit can be adjusted by adjusting the elastic coefficient of the compression spring 710 or by changing the design depth of the snap-fit ​​groove 731. The structure of the torque transmission structure 700 simplifies the debugging process during manufacturing and product adaptation.

[0029] See Figure 2 and Figure 3In some embodiments of the present invention, the abutment 720 is a ball bearing, the cross-section of the snap-fit ​​groove 731 is a semi-circle with the opening facing the ball bearing, the radial dimension of the inner peripheral wall of the snap-fit ​​groove 731 matches the diameter dimension of the ball bearing, and all the snap-fit ​​grooves 731 are connected in sequence to form a quincunx pattern. It can be imagined that the ball bearing, driven by the compression spring 710, abuts against one of the locking grooves 731. Since the radial dimension of the inner circumferential wall of the locking groove 731 matches the diameter of the ball bearing, the ball bearing can stably engage within the locking groove 731, thus maintaining stability when the rotating sleeve 500 and the mounting base 400 rotate together. When the external device is tightened and fixed to the mounting stud 410, the rotating sleeve 500 continues to rotate in the original clockwise direction. At this time, the ball bearing can move along the circumferential wall of the locking groove 731 to the other locking groove 731. During this process, the compression spring 710 is first compressed and then returns to its original deformation. While the ball bearing generates a circumferential motion relative to the rotating sleeve 500, it also moves slightly upward or downward along the length direction of the locking groove 731, thereby realizing the spiral feed motion of the rotating sleeve 500 relative to the clamping member 600. The shape of the locking groove 731 and the fact that all the locking grooves 731 are connected in sequence to form a quincunx pattern help the ball to smoothly switch into different locking grooves 731, avoiding jamming.

[0030] To ensure smooth switching of the balls into different engagement slots 731 while preventing insufficient mechanical strength between adjacent engagement slots 731, see [reference needed]. Figure 3 In some embodiments of the present invention, adjacent snap-fit ​​grooves 731 are connected by a narrow arc surface 732, which matches the outer peripheral wall of the mounting base 400 to guide the rotating sleeve 500 and the mounting base 400 to rotate relative to each other.

[0031] See Figure 1 and Figure 2 In some embodiments of the present invention, the rotating sleeve 500 has an internal threaded hole 510 inside, and the clamping member 600 includes a threaded post 610 that mates with the internal threaded hole 510. A guide rod hole 620 is provided through the middle of the threaded post 610 along its length. The connecting rod 300 is movably inserted through the guide rod hole 620. One end of the threaded post 610 has a pressing portion 630 that abuts the seat 100 against the ball head 200. It can be understood that, with the cooperation of the internal threaded hole 510 and the threaded post 610, the rotating sleeve 500 moves helically relative to the clamping member 600. Before the rotating sleeve 500 contacts the external device, the connecting rod 300 can move along the guide rod hole 620, thereby achieving opposite movements between the rotating sleeve 500 and the clamping member 600, which in turn drives the clamping member 600 to push the seat 100 against the ball head 200.

[0032] See Figure 2 and Figure 3 In some embodiments of the present invention, the movable cavity 101 has a first spherical concave surface 102 adapted to the ball head 200, the seat 100 has a spherical convex surface 103 facing the pressing part 630, the pressing part 630 has a second spherical concave surface 631 that cooperates with the spherical convex surface 103, and the centers of the spherical convex surface 103, the first spherical concave surface 102 and the second spherical concave surface 631 coincide. It is understandable that the surface of the ball head 200 can rotate freely along the first spherical concave surface 102 to achieve the angle adjustment of the external device on the mounting base 400. If the weight of the external device is large, the pressure between the ball head 200 and the first spherical concave surface 102 is large, which may cause the base 100 to have difficulty in stably pressing the ball head 200. At this time, the cooperation of the second spherical concave surface 631 and the spherical convex surface 103 is conducive to the clamping member 600 abutting against the base 100 on a large area in the direction of the ball head 200, thereby improving the clamping stability.

[0033] See Figure 1 and Figure 2 In some embodiments of the present invention, a mounting channel is provided through the middle of the rotating sleeve 500 along its axial direction. The base 100, the clamping member 600, and the mounting base 400 are arranged sequentially along the length of the mounting channel. When the rotating sleeve 500 rotates relative to the clamping member 600 to move the clamping member 600 closer to the base 100, the end of the rotating sleeve 500 near the mounting base 400 moves away from the clamping member 600 so that the mounting base 400 is accommodated within the mounting channel. This structure allows all components of the gimbal device to be housed within the mounting channel of the rotating sleeve 500, which is beneficial for structural compactness and miniaturization. It also facilitates user operation to simultaneously lock the ball joint 200 and the external device or simultaneously unlock the ball joint 200 and the external device, and allows the external device to be detached from the mounting base 400.

[0034] Specifically, the user first aligns the mounting holes on the external device with the mounting studs 410 and pre-tightens them by a certain angle. Then, the user drives the rotating sleeve 500 to rotate in the first clockwise direction. The rotating sleeve 500 drives the mounting base 400 to rotate together through the torque transmission structure 700 until the locking force between the mounting studs 410 and the external device is greater than the maximum torque that the torque transmission structure 700 can transmit. Then, the rotating sleeve 500 continues to rotate in the first clockwise direction, and the rotating sleeve 500 can rotate relative to the mounting base 400. The end of the rotating sleeve 500 away from the base 100 moves in opposite directions to the clamping member 600. The clamping member 600 moves until the opening edge of the movable cavity 101 of the base 100 abuts against the surface of the ball head 200. The end of the rotating sleeve 500 away from the base 100... The rotating sleeve 500 continues to move away from the base 100 until the mounting base 400 is received within the mounting channel. At this time, the end of the rotating sleeve 500 away from the base 100 can abut against the bottom of the external device. When the rotating sleeve 500 rotates in the second clockwise direction, the end of the rotating sleeve 500 away from the base 100 and the clamping member 600 move towards each other. The clamping member 600 leaves the base 100, and the opening edge of the movable cavity 101 no longer presses against the surface of the ball head 200. The end of the rotating sleeve 500 away from the base 100 separates from the bottom of the external device, and part of the mounting base 400 extends out of the end of the rotating sleeve 500. Then the rotating sleeve 500 continues to rotate in the second clockwise direction. The rotating sleeve 500 can drive the mounting base 400 to rotate together, and the external device is released from the mounting stud 410. Among them, one of the first clockwise direction and the second clockwise direction is clockwise and the other is counterclockwise. The direction of rotation of the internal threaded hole 510 and the threaded post 610 determines whether to lock the ball head 200 and the external device clockwise or counterclockwise.

[0035] See Figure 1 and Figure 2In some embodiments of the present invention, the cross-sectional shape of the connecting rod 300 and the cross-sectional shape of the guide rod hole 620 are both non-circular. The connecting rod 300 has a first screw portion and a second screw portion at both ends. The mounting base 400 has a first threaded mounting hole that mates with the first screw portion. The ball head 200 has a second threaded mounting hole that mates with the second screw portion. The opening of the movable cavity 101 is a frustum-shaped channel 104 that gradually expands away from the ball head 200. In this embodiment, the first screw portion is connected to the first threaded mounting hole at the bottom of the mounting base 400. The ball head 200 has a nut that mates with the second screw portion inside, and the threaded hole of this nut is the second threaded mounting hole, thereby achieving a fixed connection between the ball head 200, the connecting rod 300, and the mounting base 400. The cross-sectional shape of the connecting rod 300 and the cross-sectional shape of the guide rod hole 620 are both regular polygons. When the rotating sleeve 500 rotates relative to the clamping member 600, it guides the clamping member 600 to move up and down. In addition, the opening of the movable cavity 101 is a frustum-shaped channel 104 that gradually widens away from the ball head 200, which allows the connecting rod 300 to swing at a large angle relative to the seat 100.

[0036] See Figure 2 and Figure 3 In some embodiments of the present invention, a tube 800 is further included. The base 100 includes a lower support 110 fixedly disposed inside one end of the tube 800 and an upper support 120 partially extending outside the tube 800. Both the lower support 110 and the upper support 120 have spherical grooves that match the ball head 200. The spherical grooves of the lower support 110 and the upper support 120 define the movable cavity 101. The opening of the movable cavity 101 penetrates the portion of the upper support 120 extending out of the tube 800 and faces the lower support 110. It should be noted that the tube 800 can be connected to a camera bracket or a projection bracket to support the gimbal device. When the external device is a projector, the end of the tube 800 away from the base 100 can be fixed to the ceiling, thereby suspending the gimbal device for use.

[0037] Specifically, in this embodiment, the inner peripheral wall of the pipe 800 is provided with internal threads, and the outer peripheral walls of the lower support 110 and the upper support 120 are provided with external threads to connect to the pipe 800. In order to improve the connection firmness, the external threads of the lower support 110 and the upper support 120 can also be coated with a curable adhesive.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
