Description

Technical Field

[0001] This invention relates to a synchronous bidirectional locking gimbal device. Background Technology

[0002] In photography and projection work, pan-tilt heads are often used on tripods to mount external devices such as cameras or projectors. Pan-tilt heads come in various structures, generally offering multiple adjustable degrees of freedom to meet the needs of video recording or projection. Some pan-tilt heads incorporate quick-release mounts for rapid assembly of external devices. The external device is first fixed to the quick-release plate, which is then slidably fitted onto the quick-release mount. A first locking mechanism on the quick-release mount secures the plate in place. Additionally, to allow for angle adjustment of the external device, ball joints or rotating components that rotate around a fixed axis are often included on the pan-tilt head. These ball joints or rotating components connect to the camera tripod, and the pan-tilt head also needs a second locking mechanism to lock the ball joints or rotating components in place.

[0003] Installing and fixing the external device requires operating both the first and second locking mechanisms separately, making the installation and angle fixing procedures extremely cumbersome and inconvenient. Furthermore, adjusting the device's position also necessitates unlocking both mechanisms, adding to the inconvenience. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one of the objectives of the present invention is to provide a synchronous bidirectional locking gimbal device, which requires only one operation to lock or unlock the installation position and angle position of the external device, thereby simplifying the operation steps of installing and positioning the external device to the greatest extent and greatly improving the ease of use.

[0005] According to an embodiment of the present invention, a synchronous bidirectional locking gimbal device includes: a gimbal body; a first connector movably disposed on the gimbal body for connecting an external device; a second connector rotatably disposed on the gimbal body for connecting an external bracket to adjust the angle position of the external device; a first locking member movably disposed on the gimbal body and movable to lock or unlock the first connector; a second locking member movably disposed on the gimbal body, opposite to the first locking member, and movable to lock or unlock the second connector; and an operating component disposed on the gimbal body, simultaneously directly or indirectly contacting the first locking member and the second locking member, the operating component having a first working position and a second working position relative to the gimbal body; when the operating component is in the first working position, the operating component drives the first locking member to lock the first connector and drives the second locking member to lock the second connector; when the operating component is in the second working position, the operating component drives the first locking member to unlock from the first connector and drives the second locking member to unlock from the second connector.

[0006] The synchronous bidirectional locking gimbal device according to embodiments of the present invention has at least the following beneficial effects:

[0007] When the operating components of the above-mentioned gimbal device move to the first working position relative to the gimbal body, the operating components drive the first locking member to lock the first connecting member and drive the second locking member to lock the second connecting member, thereby achieving a synchronous bidirectional locking effect, and simultaneously locking the installation position and angle position of the external device; similarly, when the operating components move to the second working position relative to the gimbal body, the operating components drive the first locking member to unlock the first connecting member and drive the second locking member to unlock the second connecting member, thereby achieving a synchronous bidirectional unlocking effect, greatly simplifying the operation steps of installing and positioning the external device, and significantly improving the ease of use.

[0008] In some embodiments of the present invention, the gimbal body has a first channel inside, with both ends of the first channel extending through it. The first connector and the second connector are respectively located at both ends of the first channel. The first locking member and the second locking member are respectively located at the two ports of the first channel. The operating component includes a rod that can move relative to the gimbal body. One end of the rod extends into the side of the first channel. A wedge structure is provided between the end of the rod extending into the first channel and the first locking member, and between the end of the rod extending into the first channel and the second locking member. When the rod moves relative to the gimbal body, the wedge structure drives the first locking member to extend out of the first channel to press against the first connector and drives the second locking member to extend out of the first channel to press against the second connector.

[0009] In some embodiments of the present invention, the rod is a threaded push rod that is threadedly connected to the gimbal body, and the wedge structure is a frustum formed on the end of the threaded push rod that extends into the first channel. The frustum gradually narrows along the direction in which the threaded push rod extends into the first channel, and the upper and lower sides of the frustum abut against a first sphere and a second sphere, respectively.

[0010] In some embodiments of the present invention, the first sphere abuts against the third sphere via a first elastic component, and the third sphere and the second sphere respectively constitute the first locking member and the second locking member; or, the first sphere abuts against the third sphere via a first elastic component, and the second sphere abuts against the fourth sphere via a second elastic component, and the third sphere and the fourth sphere respectively constitute the first locking member and the second locking member.

[0011] In some embodiments of the present invention, the gimbal body is provided with a second channel that intersects with and penetrates the first channel. The second channel has a threaded hole inside on one side of the first channel. The threaded push rod has a threaded column portion that mates with the threaded hole. The larger end of the frustum surface is connected to the end of the threaded column portion. The smaller end of the frustum surface is connected to a cylindrical portion that extends out of the second channel on the other side of the first channel. The end of the cylindrical portion is provided with a spherical protrusion that can contact the first sphere or the second sphere.

[0012] In some embodiments of the present invention, the first connector is a quick-release plate located above the gimbal body. The gimbal body is provided with a quick-release seat for slidingly mounting the quick-release plate. The first channel is arranged vertically and extends upward through the quick-release seat. The lower part of the gimbal body is provided with a mounting cavity with an opening facing downward. The second connector includes a ball head rotatably disposed in the mounting cavity. The ball head is connected to a connecting rod extending out of the opening of the mounting cavity. A pressing member is movably raised and lowered in the mounting cavity toward the lower end of the first channel. When the first locking member extends out of the upper end of the first channel and presses the quick-release plate against the quick-release seat, the second locking member extends out of the lower end of the first channel and presses the pressing member against the ball head.

[0013] In some embodiments of the present invention, the first connecting member is a quick-release plate located above the gimbal body. The gimbal body is provided with a quick-release seat for the quick-release plate to be slidably fitted. The first channel is arranged vertically and extends upward through the quick-release seat. The second connecting member includes a pivot member rotatably disposed at the lower part of the gimbal body about a horizontal axis. The outer peripheral wall of the pivot member faces the lower end of the first channel. The side wall of the pivot member is connected to a threaded rod or threaded sleeve for connecting an external bracket. When the first locking member extends out from the upper end of the first channel and presses the quick-release plate against the quick-release seat, the second locking member extends out from the lower end of the first channel and presses against the pivot member.

[0014] In some embodiments of the present invention, the sidewall of the rotating shaft is provided with a rotating channel recessed in its radial direction, the threaded rod or the threaded sleeve is axially rotatable about the rotating channel, and the gimbal body is provided with an angle positioning mechanism capable of locking the threaded rod or the threaded sleeve onto the rotating shaft.

[0015] In some embodiments of the present invention, the outer peripheral wall of one end of the threaded sleeve that extends into the rotating channel is provided with a first annular groove, the rotating shaft is axially provided with a third channel communicating with the rotating channel, and the angle positioning mechanism includes a first threaded push rod that can move along the third channel to abut against the first annular groove.

[0016] In some embodiments of the present invention, the third channel is provided with a ball bearing disposed opposite to the end of the first threaded push rod, the shape and size of the cross-section of the first annular groove are matched with the diameter of the ball bearing, and the ball bearing is connected to a third elastic component that drives it to abut against the first annular groove.

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.

[0033] See Figures 1 to 5 , or see Figures 6 to 8 An embodiment of the present invention provides a synchronous bidirectional locking gimbal device, comprising: a gimbal body 100; a first connector 200 movably disposed on the gimbal body 100 for connecting an external device; a second connector 300 rotatably disposed on the gimbal body 100 for connecting an external bracket to adjust the angle and position of the external device; a first locking member 400 movably disposed on the gimbal body 100 and movable to lock or unlock the first connector 200; a second locking member 500 movably disposed on the gimbal body 100, opposite to the first locking member 400, and movable to lock or unlock the second connector 300; and an operating component 600 disposed on the gimbal body 100. Simultaneously, the operating component 600 directly or indirectly contacts the first locking member 400 and the second locking member 500, and has a first working position and a second working position relative to the gimbal body 100; when the operating component 600 is in the first working position, the operating component 600 drives the first locking member 400 to lock the first connecting member 200 and drives the second locking member 500 to lock the second connecting member 300; when the operating component 600 is in the second working position, the operating component 600 drives the first locking member 400 to unlock from the first connecting member 200 and drives the second locking member 500 to unlock from the second connecting member 300.

[0034] When the operating component 600 of the above-mentioned gimbal device moves to the first working position relative to the gimbal body 100, the operating component 600 drives the first locking component 400 to lock the first connecting component 200 and drives the second locking component 500 to lock the second connecting component 300, thereby achieving a synchronous bidirectional locking effect, and simultaneously locking the installation position and angle position of the external device; similarly, when the operating component 600 moves to the second working position relative to the gimbal body 100, the operating component 600 drives the first locking component 400 to unlock the first connecting component 200 and drives the second locking component 500 to unlock the second connecting component 300, thereby achieving a synchronous bidirectional unlocking effect, greatly simplifying the operation steps of installing and positioning the external device, and significantly improving the ease of use.

[0035] See Figure 3 and Figure 4 , or see Figure 7 and Figure 8In some embodiments of the present invention, the gimbal body 100 has a first channel 110 inside, with both ends of the first channel 110 extending through it. The first connector 200 and the second connector 300 are respectively located at both ends of the first channel 110. The first locking member 400 and the second locking member 500 are respectively located at the two ports of the first channel 110. The operating component 600 includes a rod that can move relative to the gimbal body 100. One end of the rod extends into the side of the first channel 110, and the other end extends out of the channel. The gimbal body 100 has wedge-shaped structures 610 between the end of the rod extending into the first channel 110 and the first locking member 400, and between the end of the rod extending into the first channel 110 and the second locking member 500. When the rod moves relative to the gimbal body 100, the wedge-shaped structures 610 drive the first locking member 400 to extend partially out of the first channel 110 to press against the first connecting member 200, and drive the second locking member 500 to extend partially out of the first channel 110 to press against the second connecting member 300. It can be understood that when the end of the rod extending into the first channel 110 moves along the length of the rod, the wedge-shaped structures 610 can drive the first locking member 400 and the second locking member 500 to move away from each other, thereby synchronously driving the first locking member 400 and the second locking member 500 to extend out of the two ends of the first channel 110 respectively, pressing against the first connecting member 200 and the second connecting member 300 by pushing outwards. In other embodiments, the rod can also be replaced by a method that rotates only relative to the gimbal body 100, and two eccentric parts are provided at the end of the rod. When the rod rotates to the point where the two eccentric parts abut against the first locking member 400 and the second locking member 500 respectively, the first connecting member 200 and the second connecting member 300 are tightened. When the rod rotates to the point where the two eccentric parts are misaligned with the first locking member 400 and the second locking member 500, the first connecting member 200 and the second connecting member 300 are no longer tightened.

[0036] See Figure 2 , Figure 3 and Figure 4 , or see Figure 7 and Figure 8In some embodiments of the present invention, the rod is a threaded push rod that is threadedly connected to the gimbal body 100, and the wedge structure 610 is a frustum formed on one end of the threaded push rod that extends into the first channel 110. The frustum gradually narrows along the direction in which the threaded push rod extends into the first channel 110, and the upper and lower sides of the frustum abut against the first sphere 710 and the second sphere, respectively. It should be noted that when the first ball 710 moves upward, it can lock the first connector 200, and when the second ball moves downward, it can lock the second connector 300. When neither the first connector 200 nor the second connector 300 is locked, the outer peripheral wall of the smaller end of the frustum surface is in contact with the first ball 710 and the second ball. As the threaded push rod is screwed in, both the first ball 710 and the second ball move from the smaller end to the larger end of the frustum surface, thus moving the first ball 710 and the second ball away from each other. Similarly, as the threaded push rod is screwed out, the first ball 710 and the second ball can also move from the larger end to the smaller end of the frustum surface, thus moving the first ball 710 and the second ball closer to each other. That is, by rotating the threaded push rod in both directions, the first connector 200 and the second connector 300 can be locked and unlocked simultaneously. The structure is very simple and very convenient to use. Of course, in other embodiments, the first sphere 710 and the second sphere can also be replaced by the first slider and the second slider, respectively. The wedge structure 610 consists of a first inclined surface on the first slider and a second inclined surface on the second slider that is opposite to the first inclined surface. The second inclined surface and the first inclined surface are symmetrically distributed about the axis of the rod. When the threaded push rod is screwed in, it can drive the first slider and the second slider to move away from each other.

[0037] See Figures 2 to 4 In some embodiments of the present invention, the first sphere 710 abuts against a third sphere via a first elastic component 720, and the third sphere and the second sphere respectively constitute the first locking member 400 and the second locking member 500. In this embodiment, the first elastic component 720 includes a first spring and a first elastic compression block abutting between the first sphere 710 and the third sphere. The first elastic compression block is generally made of rubber and can transmit a large thrust, which helps to ensure that the first locking member 400 is tightened while the second locking member 500 is tightened. In addition, if the first sphere 710 and the third sphere are in rigid contact, the manufacturing precision requirements between the components are extremely high, and defective products are likely to occur. The combination of the first spring and the first elastic compression block can realize the transmission of the thrust, reduce the requirements for the manufacturing precision of the components, and the first elastic compression block has a large elastic coefficient, avoiding insufficient force transmitted by the first spring.

[0038] Or see Figure 7 and Figure 8The first sphere 710 abuts against the third sphere via the first elastic component 720, and the second sphere abuts against the fourth sphere via the second elastic component 730. The third sphere and the fourth sphere respectively constitute the first locking member 400 and the second locking member 500. In this embodiment, the second elastic component 730 includes a second spring and a second elastic compression block abutting between the second sphere and the fourth sphere. The second elastic compression block is generally made of rubber and can transmit a large thrust, which helps to ensure that the first locking member 400 is tightened while the second locking member 500 is tightened. In addition, if the second sphere and the fourth sphere are in rigid contact, the manufacturing precision requirements between the components are extremely high, which can easily lead to defective products. The second spring can realize the transmission of the thrust, which can reduce the requirements for the manufacturing precision of the components. The second elastic compression block has a large elastic coefficient, which avoids insufficient force transmitted by the second spring.

[0039] See Figure 4 Or see Figure 8 In some embodiments of the present invention, the gimbal body 100 is provided with a second channel 120 that intersects with and penetrates the first channel 110. The second channel 120 has a threaded hole 121 inside on one side of the first channel 110. The threaded push rod has a threaded column portion that mates with the threaded hole 121. The larger end of the frustum surface is connected to the end of the threaded column portion. The smaller end of the frustum surface is connected to a cylindrical portion 620 that extends out of the second channel 120 on the other side of the first channel 110. The end of the cylindrical portion 620 is provided with a spherical protrusion 630 that can contact the first sphere 710 or the second sphere. Understandably, when the threaded push rod is rotated, the threaded column rotates relative to the threaded hole 121 and moves forward. The first ball 710 and the second ball move from the position of contacting the cylindrical part 620 along the smaller end to the larger end of the frustum surface. When the first ball 710 and the second ball are in contact with the cylindrical part 620 and the spherical protrusion 630 at the same time, the first connector 200 and the second connector 300 are in the unlocked state.

[0040] See Figure 7 and Figure 8In some embodiments of the present invention, the first connector 200 is a quick-release plate located above the gimbal body 100. The gimbal body 100 is provided with a quick-release seat 130 for slidingly mounting the quick-release plate. The first channel 110 is arranged vertically and extends upward through the quick-release seat 130. The lower part of the gimbal body 100 is provided with a mounting cavity 140 with an opening facing downward. The second connector 300 includes a ball head rotatably disposed in the mounting cavity 140. The ball head is connected to a connecting rod extending out of the opening of the mounting cavity 140. A pressing member 150 is movably and vertically disposed in the mounting cavity 140 toward the lower end of the first channel 110. When the gimbal device with the above structure needs to be connected to and fixed with external equipment, the external equipment is first connected to the quick-release plate, and then the quick-release plate is slidably embedded in the quick-release base 130. Then, the operating component 600 is driven to move relative to the gimbal body 100. One end of the rod extending into the first channel 110 drives the first locking component 400 and the second locking component 500 to move away from each other through the wedge structure 610. The first locking component 400 extends out of the upper end of the first channel 110 and presses the quick-release plate against the quick-release base 130. At the same time, the second locking component 500 extends out of the lower end of the first channel 110 and presses the pressing component 150 against the ball head, thereby fixing the position of the quick-release plate and the angle of the ball head. It is widely applicable to multi-degree-of-freedom shooting needs.

[0041] See Figures 2 to 4In some embodiments of the present invention, the first connecting member 200 is a quick-release plate located above the gimbal body 100. The gimbal body 100 is provided with a quick-release seat 130 for the quick-release plate to be slidably fitted. The first channel 110 is arranged vertically and passes through the quick-release seat 130 upward. The second connecting member 300 includes a pivot member 310 rotatably disposed at the lower part of the gimbal body 100 about a horizontal axis. The outer peripheral wall of the pivot member 310 faces the lower end of the first channel 110. The side wall of the pivot member 310 is connected to a threaded rod or threaded sleeve 320 for connecting an external bracket. When the first locking member 400 extends out of the upper end of the first channel 110 and presses the quick-release plate against the quick-release seat 130, the second locking member 500 extends out of the lower end of the first channel 110 and presses against the pivot member 310. When the gimbal device with the above structure needs to be connected to an external device, the external device is first connected to the quick-release plate. Then, the quick-release plate is slidably mounted on the quick-release base 130. The operating component 600 is then driven to move relative to the gimbal body 100. One end of the rod extending into the first channel 110 drives the first locking member 400 and the second locking member 500 to move away from each other via the wedge structure 610. The first locking member 400 extends from the upper end of the first channel 110 and presses the quick-release plate against the quick-release base 130. Simultaneously, the second locking member 500 extends from the lower end of the first channel 110 and locks the rotating shaft 310, thereby fixing the position of the quick-release plate and the tilt angle of the external device on the quick-release plate. This is widely applicable to shooting needs requiring adjustment of the tilt angle. Furthermore, in this embodiment, a return spring is provided between the rotating shaft 310 and the gimbal body 100, which can drive the rotating shaft 310 to rotate up and down and then return to its original position, providing a positive effect for wide-angle shooting in the vertical direction.

[0042] See Figures 3 to 5 In some embodiments of the present invention, in order to add left and right angle adjustment function on the basis of tilt angle adjustment, thereby meeting the needs of panoramic shooting, the side wall of the pivot 310 is provided with a rotation channel 330 radially recessed. The threaded rod or the threaded sleeve 320 is rotatably arranged around the rotation channel 330. The gimbal body 100 is provided with an angle positioning mechanism 340 capable of locking the threaded rod or the threaded sleeve 320 onto the pivot 310. It can be understood that when it is necessary to realize the left and right deflection of the external device, the angle positioning mechanism 340 does not lock the threaded rod or the threaded sleeve 320; when it is necessary to fix the angular position of the external device in the left and right directions, the angle positioning mechanism 340 locks the threaded rod or the threaded sleeve 320.

[0043] See Figure 5In some embodiments of the present invention, the outer peripheral wall of one end of the threaded sleeve 320 extending into the rotation channel 330 is provided with a first annular groove 321, and the axially penetrating shaft 310 is provided with a third channel 350 communicating with the rotation channel 330. The angle positioning mechanism 340 includes a first threaded push rod that can move along the third channel 350 to abut against the first annular groove 321. It can be understood that the threaded sleeve 320 is connected to the external bracket. When the end of the first threaded push rod is not abutting against the first annular groove 321, the entire gimbal device can rotate relative to the external bracket around the axial direction of the threaded sleeve 320. When the end of the first threaded push rod is pressed against the bottom of the first annular groove 321, the angular position of the external device in the left and right directions can be fixed. The angle positioning mechanism 340 has a very simple structure and is very convenient to use.

[0044] See Figure 2 and Figure 5 In some embodiments of the present invention, the third channel 350 is provided with a ball 360 disposed opposite to the end of the first threaded push rod. The shape and size of the cross-section of the first annular groove 321 match the diameter of the ball 360. The ball 360 is connected to a third elastic component 370 that drives it to abut against the first annular groove 321. It should be noted that when the end of the first threaded push rod is not abutting against the first annular groove 321, the ball 360 abuts against the first annular groove 321 under the action of the third elastic component. This not only guides the rotation of the threaded sleeve 320 but also prevents the threaded sleeve 320 from disengaging from the rotating component along the third channel 350. Moreover, when the end of the first threaded push rod abuts against the first annular groove 321, the ball 360 also abuts against the first annular groove 321, achieving a force balance and reducing the load on the first threaded push rod.

[0045] 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.

[0046] 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.
