TECHNICAL FIELD

Embodiments of the present disclosure relate to the field of a mobile device holding system, and in particular, to a gimbal stabilizer for improved stability for a gimbal.

BACKGROUND

With an increase in demand for cell phone photography and increased photo quality requirements, more people choose to use a mobile device stabilizer as an auxiliary tool for daily photo shooting. However, the existing mobile device stabilizers on the market are generally large, inconvenient to carry, and have very simple functions, which have made people reluctant to use these stabilizers.

Accordingly, there is an unmet need for an improved mobile device stabilizer that is more functional, more compact in size, and convenient to carry.

SUMMARY

Embodiments of the disclosure provide a gimbal stabilizer. The gimbal stabilizer includes a base, a first rotary electric motor, a second rotary electric motor, and an arm. The arm includes a first arm and a second arm. One end of the first arm is pivotally installed on the base through the first rotary electric motor. The second rotary electric motor is connected to the other end of the first arm through a first articulated shaft. The second rotary electric motor is further configured to connect to one end of the second arm to drive the second arm to rotate.

Embodiments of the disclosure also provide another gimbal stabilizer. The another gimbal stabilizer includes a first arm and a first rotary electric motor installed at one end of the first arm. The another gimbal stabilizer further includes a second arm and a second rotary electric motor. The first rotary electric motor is connected to one end of the second arm to drive the second arm to rotate. The second rotary electric motor is connected to the other end of the second arm.

Embodiments of the disclosure provide yet another gimbal stabilizer. The another gimbal stabilizer includes a handle, a stabilizer body, and a first charging interface. The handle includes an accommodating space and a second battery inside the handle. A load is connectable to the stabilizer body. The accommodating space of the handle is configured to accommodate the stabilizer body. The first charging interface is connected to the second battery to charge the load when the load is placed on the first charging interface.

Embodiments of the disclosure provide still another gimbal stabilizer. The another gimbal stabilizer includes a handle that includes an accommodating space therein. The another gimbal stabilizer further includes a first rotary electric motor and a second rotary electric motor, where the first rotary electric motor is mounted on the handle. The another gimbal stabilizer includes a first arm. The first arm includes a first arm body, a first rotation shaft, and a second rotation shaft. The first rotary electric motor is connected to one end of the first arm body through the first rotation shaft to drive the first arm body to rotate by a rotation of the first rotary electric motor around an axis of the first rotary electric motor. The other end of the first arm body is connected to the second rotary electric motor through the second rotation shaft.

EMBODIMENT 1

FIG. 1 illustrates an exploded view of a gimbal stabilizer 100 according to Embodiment 1 of the present disclosure. As shown in FIG. 1, gimbal stabilizer 100 may include a base 30, a first rotary electric motor 22, a second rotary electric motor 23, and an arm portion 21. Arm portion 21 may further include a first arm 211 and a second arm 212. One end (e.g., a lower end) of first arm 211 may be pivotally mounted on base 30 through first rotary electric motor 22. First rotary electric motor 22 may be configured to drive first arm 211 to rotate around a first rotation axis 01 relative to base 30, where first rotation axis 01 may parallel to, for example, a centerline of base 30. Second rotary electric motor 23 may be connected to the other end (e.g., the upper end) of first arm 211 through an articulated shaft 217. One end of second arm 212 may be connected to second rotary electric motor 23 so that second rotary electric motor 23 can drive second arm 212 to rotate around a second rotation axis 02.

FIG. 2 illustrates a schematic diagram of a folded state of gimbal stabilizer 100 according to an embodiment of the present disclosure. As shown in FIG. 2, second arm 212 may rotate around articulated shaft 217 so as to switch between a folded position and an unfolded position. When second arm 212 is in the folded position, second arm 212 may be adjacent to first arm 211 and may be aligned even with first arm 211. That is, in the folded position, second arm 212 and second rotary electric motor 23 may be placed together in a recess of first arm 211. At this point, first arm 211 and second arm 212 may parallel, or an angle between first arm 211 and second arm 212 may be nominal, for example, between 0° and 10°.

In some embodiments, as shown in FIGs. 1-2, first arm 211 may be L-shaped. When second arm 212 rotates closer to first arm 211 around articulated shaft 217, second arm 212 may be in the folded position. Second arm 212 may be then stored in the recess of first arm 211, so that arm portion 21 can be folded into a very compact form for easy storage. Specifically, as shown in FIG. 1, first arm 211 may include a horizontal section 2111 and a vertical section 2112. Horizontal section 2111 may be arranged in the horizontal direction, and vertical section 2112 may be arranged in the vertical direction. An angle between horizontal section 2111 and vertical section 2112 may be between 80° to 100°, for example, 90°. In some embodiments, the length of vertical section 2112 may be greater than the length of horizontal section 2111, so that first arm 211 is L-shaped. First rotary electric motor 22 may be disposed in horizontal section 2111. The output shaft of first rotary electric motor 22 may be positioned vertically, and the housing of first rotary electric motor 22 may be fixed to horizontal section 2111. The output shaft of first rotary electric motor 22 may be fixedly connected to base 30, so that first rotary electric motor 22 may drive first arm 211 to rotate around first rotation axis 01. Vertical section 2112 may be connected to a pitch bracket 213 through articulated shaft 217, so that pitch bracket 213 can rotate around articulated shaft 217 relative to first arm 211. Second arm 212 may include a roll bracket 214. One end of pitch bracket 213 may be connected to vertical section 2112 by articulated shaft 217, and the other end of pitch bracket 213 may be fixedly connected to the housing of second rotary electric motor 23. The output shaft of second rotary electric motor 23 may be fixedly connected to roll bracket 214. Second rotary electric motor 23 may be configured to drive roll bracket 214 to rotate around a second rotation axis 02 relative to pitch bracket 213, where second rotation axis 02 may be perpendicular to articulated shaft 217.

In some embodiments, as shown in FIG. 1, gimbal stabilizer 100 may further include a third rotary electric motor 24. Third rotary electric motor 24 may be connected to the other end of second arm 212. Roll bracket 214 may be fixedly connected to the housing of third rotary electric motor 24. The output shaft of third rotary electric motor 24 may be fixedly connected to a load connection frame 215. Third rotary electric motor 24 may be configured to drive load connection frame 215 to rotate around a third rotation axis 03 relative to roll bracket 214. Third rotation axis 03 and second rotation axis 02 may form an included angle in between. Load connection frame 215 may be configured to connect to a load 60 (as shown in FIG. 3) . The structure shown in FIG. 1 includes a first arm, a second arm, a first rotary electric motor, a second rotary electric motor, and a third rotary electric motor. However, the present disclosure is not limited thereto, and may also include more or fewer arms and rotary electric motors.

In some embodiments, as shown in FIGs. 1-2, gimbal stabilizer 100 may further include a handle 10. Handle 10 may have an accommodating space inside the handle, and base 30 may be stored in the accommodating space. Load 60 may be placed on handle 10 or load 60 may be connected to load connection frame 215. Load 60 may optionally be an electronic device such as a mobile phone, a tablet, or a camera, etc. Gimbal stabilizer 100 may have an extended state and a storage state. FIGs. 3-4 respectively illustrate schematic diagrams of an extended state and a storage state of the gimbal stabilizer according to an embodiment of the present disclosure. In the extended state, as shown in FIG. 3, arm portion 21 may extend out of handle 10 and at least partially extends outside the accommodating space, and load 60 may be connected to arm portion 21 through load connection frame 215 and stably supported by arm portion 21. In this state, gimbal stabilizer 100 may operate to control the load. In the storage state, as shown in FIG. 4, arm portion 21 and base 30 may be completely stored inside the accommodating space. In this state, gimbal stabilizer 100 may be in a non-operating state. By storing arm portion 21 in the accommodating space, the overall size of gimbal stabilizer 100 may be reduced, to make it more portable. As can be seen, by whether or not storing arm portion 21 inside the accommodating place, gimbal stabilizer 100 may be freely switched between an extended state and a storage state. For instance, when gimbal stabilizer 100 is used, arm portion 21 may be pulled out of the accommodating space, to keep arm portion 21 outside handle 10, so as to connect and support load 60. When gimbal stabilizer 100 is not in use, arm portion 21 may be folded and put back into the accommodation space.

FIG. 5 illustrates a cross-sectional view of a handle according to an embodiment of the present disclosure. As shown in FIG. 5, handle 10 may have a hollow structure, where the unoccupied part is the accommodating space. The upper end of handle 10 may be an open end 11, so that arm portion 21 may be put into the interior of handle 10 from open end 11 (as shown in FIG. 2) . The lower end of handle 10 may be provided with an end cap 12, which may cover the lower end of handle 10. The end cap 12 may be connected with handle 10 at one point so that the lower end of handle 10 can be sealed by end cap 12. When gimbal stabilizer 100 is in the extended state, as shown in FIG. 3, arm portion 21 may remain connected with open end 11 of handle 10 due to its connection with base 30. It is to be noted that, in some embodiments, the stabilizer body may also be completely disconnected from handle 10, and then stored inside handle 10 for easy carrying after being folded.

Those skilled in the art may understand that open end 11 may also be located at the lower end of handle 10 so that arm portion 21 is connected to the upper end of handle 10. In this way, when gimbal stabilizer 100 is in an extended state, arm portion 21 may then remain connected with the upper end of handle 10.

Referring back to FIGs. 1 and 2, third rotary electric motor 24 may be connected to the other end of second arm 212. Third rotary electric motor 24 may be configured to connect with load 60, and may drive load 60 to rotate around third rotation axis 03. Arm portion 21 may be folded and unfolded. When arm portion 21 is folded, first arm 211 and second arm 212 are folded so that they can be stored inside handle 10. Gimbal stabilizer 100 is then in the storage state, thereby reducing the overall space occupied by the gimbal stabilizer. When arm portion 21 is unfolded, first arm 211 and second arm 212 may rotate independently and/or cooperatively, so that arm portion 21 can be adjusted with multiple degrees of freedom. This then allows load 60 to be adjusted with multiple degrees of freedom. For example, the yaw angle, pitch angle, and roll angle of load 60 can be freely adjusted. In some embodiments, each of the first, second, or third rotary electric motor may be responsible for one of a yaw angle, pitch angle, and roll angle, respectively.

Referring further to FIGs. 1 and 2, the rotation axis of first arm 211 (i.e., first rotation axis 01) may be perpendicular to articulated shaft 217, articulated shaft 217 may be perpendicular to the rotation axis of second rotary electric motor 23 (i.e., second rotation axis 02) , and the rotation axis of second rotary electric motor 23 may be perpendicular to the rotation axis of third rotary electric motor 24 (i.e., third rotation axis 03) .

FIG. 6 illustrates a schematic diagram of a gimbal stabilizer according to an embodiment of the present disclosure. As shown in FIG. 6, base 30 may slidably fit with the inner wall of handle 10 inside the accommodating space, and may slide between a first position and a second position along the direction of handle 10 in the accommodating space. The cross-sectional shape of base 30 may, for example, generally match or be the same as the cross-sectional shape of the accommodating space, e.g., may be a rectangular shape with rounded corners as shown in FIGs. 1-6. When base 30 is in the first position, arm portion 21 extends outward from open end 11 of handle 10, and gimbal stabilizer 100 may be then in the extended state and may be used to connect a load 60. When base 30 is in the second position, arm portion 21 may be retracted into the accommodating space of handle 10, and gimbal stabilizer 100 is thus in the storage state. The inclusion of a base 30 facilitates and improves the flexibility of organizing arm portion 21 and handle 10.

In some embodiments, handle 10 may have a first locking element and a second locking element, where the first locking element may be configured to lock base 30 in the first position, and the second locking element may be configured to lock base 30 in the second position. Specifically, when base 30 moves, relative to handle 10, to the first locking element, the first locking element may lock base 30 in the first position. When base 30 moves, relative to handle 10, to the second locking element, the second locking element may lock base 30 in the second position. The inclusion of a first locking element and a second locking element may allow base 30 to be optionally locked at different positions, such as the first position or the second position.

FIG. 7 illustrates a schematic diagram of a base according to an embodiment of the present disclosure. As shown in FIG. 7, the first locking element and the second locking element can be either a snap-in plug or a locking hole. Base 30 may then include either a locking hole or snap-in plug that matches the snap-in plug or locking hole in the first locking element and the second locking element. Optionally, referring to FIG. 4, the first locking element may be a locking hole 141 that matches a snap-in plug 31, and the second locking element may be a locking hole 142 that matches snap-in plug 31. The two locking

holes

141 and 142 may respectively correspond to the first position and the second position. The locking holes 141 and 142 may be located on the side wall of handle 10. When snap-in plug 31 slides into locking hole 141, snap-in plug 31 may be locked by the locking hole 141 and locked at the first position. When snap-in plug 31 slides into locking hole 142, snap-in plug 31 may be locked by locking hole 142 at the second position. Base 30 can be unlocked from the first position or the second position by pressing snap-in plug 31. Specifically, when base 30 slides inside handle 10, snap-in plug 31 moves against the inner wall of handle 10. Accordingly, snap-in plug 31 may be elastically deformed due to the compression formed by the inner wall of handle 10. When base 30 moves to the first position, snap-in plug 31 may bounce and be stopped by the peripheral wall of locking hole 141, and thus lock base 30 in the first position. After snap-in plug 31 exits locking hole 141 in the first position, base 30 may continue to slide relative to the inner wall of handle 10. When base 30 slides to the second position, snap-in plug 31 may bounce again and get stuck by the peripheral wall of locking hole 142, and thus lock base 30 in the second position.

In some embodiments, in order to facilitate the locking of snap-in plug 31 by locking

holes

141 and 142, snap-in plug 31 may be an elastic structure, and locking

holes

141 and 142 may be through holes. When snap-in plug 31 slides inside handle 10, snap-in plug 31 may be in a compressed state. When snap-in plug 31 slides to the position of locking hole 141 or locking hole 142, snap-in plug 31 may bounce under the action of elastic force and extend into locking hole 141 or locking hole 142, so that base 30 is locked into handle 10. To slide base 30, snap-in plug 31 may be pressed to eject snap-in plug 31 out of locking

hole

141 or 142. That is, snap-in plug 31 may be released from the lock by locking

hole

141 or 142. Snap-in plug 31 and locking

hole

141 or 142 collectively coordinate the locking or unlocking of base 30 with handle 10.

Those skilled in the art may understand that the arrangement of the snap-in plug and the locking holes can be switched. That is, a snap-in plug can be disposed on the first locking element and the second locking element and base 30 can be provided with a locking hole. This alternative arrangement can still enable the foregoing locking and unlocking mechanism, which will not be repeated here. In some embodiments, base 30 may be alternatively provided with spring ball (s) instead of a snap-in plug, to work with the locking holes in the first locking element and the second locking element. In such embodiments, the locking hole may be a blind hole located on the inner wall of handle 10. After the spring ball (s) on base 30 slides to the locking hole, handle 10 may be locked into base 30.

Further, in order to facilitate the sliding of base 30 with respect to handle 10, one of base 30 and handle 10 may be provided with a guide rail, while the other one is provided with a sliding table matching the guide rail. The guide rail may extend along the length direction of handle 10. The inclusion of the sliding table and the guide rail may guide the sliding of base 30 inside the handle, to allow the base 30 to move stably and flexibly relative to handle 10. FIG. 8 shows a schematic diagram of the internal structure of the handle according to an embodiment of the present disclosure. As shown in FIG. 8, a guide rail 15 may be disposed on the inner wall of handle 10. As shown in FIG. 7, a sliding table 38 matching guide rail 15 may be disposed on the side wall of base 30. Sliding table 38 may be slidingly engaged with guide rail 15.

In some embodiments, the disclosed gimbal stabilizer 100 may further include one or more power supplies and control units. For instance, gimbal stability 100 may further include a first battery 33 and a controller 34. To save space, first battery 33 and controller 34 may be integrated into base 30, as shown in FIG. 1. First battery 33 may be configured to supply power to first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24. Controller 34 may be configured to control operations of first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24. When arm portion 21 is assembled with base 30, first arm 211 may be slidingly fitted into base 30. First battery 33 may be electrically connected to first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24, and provide electrical power to these motors. Controller 34 may be electrically connected with first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24 for controlling the operation of arm portion 21. Controller 34 may be, for example, a PCB circuit board, on which a corresponding chip or circuit may be integrated. Controller 34 may be electrically connected to first battery 33, first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24.

In some embodiments, as shown in FIGs. 1-2, handle 10 may further include a second battery 18, which is configured to charge first battery 33. Second battery 18 may be integrated onto the side wall or the bottom of handle 10.

In some embodiments, handle 10 may include a wireless charging module (not shown in the figure) . The wireless charging module may be coupled to second battery 18 and may be configured to wirelessly charge load 60 placed on handle 10.

In some embodiments, as shown in FIGs. 1 and 5, gimbal stabilizer 100 may further include an operation unit 40 configured to control operations of first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24 through controller 34. Operation unit 40 may be detachably attached to handle 10, and may be wirelessly connected to and communicate with arm portion 21 and load 60 for remote control. Optionally, operation unit 40 may communicate with arm portion 21 and load 60 via

By inclusion of operation unit 40, it is more convenient to remotely control arm portion 21, and thus the operation is more flexible. For example, through operation unit 40, the attitude and orientation of arm portion 21 may be controlled, to adjust the yaw angle, pitch angle, and roll angle of load 60. In addition, operation unit 40 may be detachably attached to handle 10, to facilitate the storage of operation unit 40. In some embodiments, as shown in FIG. 5, operation unit 40 may be mounted on handle 10, and thus can achieve a local control instead. In some embodiments, operation unit 40 is a remote control instead (which may be also referred to remote control 40) . That is, operation unit 40 may be detached from handle 10, and can control arm portion 21 remotely.

In some embodiments, as shown in FIG. 4, when gimbal stabilizer 100 is in the storage state, arm portion 21 may be retracted into the accommodating space. Remote control 40 may then cover open end 11 of handle 10, so as to seal the accommodating space. This also provides protection of arm portion 21 stored in handle 10. In some embodiments, a side wall of handle 10 may further include a mounting slot 16 for holding remote control 40 (as shown in FIG. 10) . Accordingly, when gimbal stabilizer 100 is in the extended state, remote control 40 may be attached to the mounting slot 16 of handle 10. That is, when handle 10 is in use, as shown in FIG. 3, remote control 40 may be mounted to the mounting slot 16, facilitating a user to control arm portion 21 locally.

FIG. 9 illustrates a schematic structural diagram of a handle according to an embodiment of the present disclosure, and FIG. 10 illustrates a schematic diagram of a hand-held use of a gimbal stabilizer according to an embodiment of the present disclosure. As shown in FIGs. 9 and 10, gimbal stabilizer 100 may further include a fixed footpad 120 and movable footpad (s) 13. Fixed footpad 120 and movable footpad (s) 13 may be located at the bottom of handle 10 to support gimbal stabilizer 100. Specifically, fixed footpad 120 may be attached to end cap 12 and protrude from end cap 12. Optionally, there may be two movable footpads 13, which are movably attached to end cap 12. The two movable footpads 13 may be able to rotate relative to handle 10. When the two movable footpads 13 spread out, the two movable footpads 13 and fixed footpad 120 may form a tripod (as shown in FIG. 10) , to stably support handle 10, so that base 30 and arm portion 21 as a whole may stably stand on a desktop or other countertops, such as the surface of a car dashboard. When the two movable footpads 13 are retracted for storage, the contours of the two movable footpads 13 may overlap with the contour of fixed footpad 120, and the contours of the stacked two movable footpads 13 and fixed footpad 120 may match the contour of end cap 12. Optionally, fixed footpad 120 and end cap 12 may be formed through integrated molding, which is convenient for processing and manufacturing.

In some embodiments, the two movable footpads 13 may be symmetrically distributed with respect to end cap 12 when the two movable footpads 13 spread out. Each movable footpad 13 may include one end rotatably connected with end cap 12, and the other end may be a movable end, which may rotate when movable footpads 13 spread out. According to an embodiment of the present disclosure, the connection end of each movable footpad 13 may include a pillow block 131 (as shown in FIG. 6) , and end cap 12 may include two shaft holes 122 corresponding to two pillow blocks 131, as shown in FIG. 9. Pillow block 131 may be inserted into and become rotatable inside shaft hole 122, to allow movable footpads 13 to spread out.

In some embodiments, the lower end of handle 10 may be an open end, while the upper end is a closed end. End cap 12 may be flexibly attached to handle 10. When gimbal stabilizer 100 is switched from a storage state to an extended state, arm portion 21 may be taken out of handle 10 from the lower end opening of handle 10 and then connected to the upper end of handle 10. When gimbal stabilizer 100 is in the extended state, end cap 12 closes the lower end opening of handle 10. The two movable footpads 13 may spread out and together with fixed footpad 120 form a tripod.

In some embodiments, an expansion hole 121 may be further disposed on fixed footpad 120, as shown in FIG. 9. The inclusion of expansion hole 121 may facilitate a connection of handle 10 with a selfie stick or an attachment of handle 10 to another platform such as a vehicle. Optionally, as shown in FIG. 9, expansion hole 121 and the two shaft holes 122 may be respectively located at the two ends of end cap 12, to prevent movable footpad 13 from covering expansion hole 121.

FIG. 11 illustrates a schematic diagram of a load protection case according to an embodiment of the present disclosure. As shown in FIG. 11, gimbal stabilizer 100 may further include a load protection case 50. Load protection case 50 may be used to hold a load 60. Load protection case 50 may include one or more openings 501 for the camera lens on load 60 used for shooting or taking pictures. As shown in FIGs. 1 and 6, arm portion 21 may include a first quick-release fixing structure 216. As shown in FIG. 11, load protection case 50 may be provided with a second quick-release fixing structure 51 for interacting with first quick-release fixing structure 216. Through the interaction between first quick-release fixing structure 216 and second quick-release fixing structure 51, load protection case 50 may be quickly attached to or detached from arm portion 21, thereby improving the attachment/detachment efficiency.

In some embodiments, first quick-release fixing structure 216 may include a first boss. As shown in FIG. 11, second quick-release fixing structure 51 may include a groove 511 corresponding to the first boss. When load protection case 50 is mounted onto gimbal stabilizer 100, the first boss and groove 511 may be interference fit, to allow a quick detachment of second quick-release fixing structure 51 from first quick-release fixing structure 216. Optionally, the cross-sectional shape of the first boss may be a circle, a square, a triangle, or other conventional shapes, or an irregular shape. In some embodiments, as shown in FIG. 6, the cross-sectional shape of the first boss is circular, and the corresponding groove 511 is a round groove.

In some embodiments, as shown in FIG. 11, load protection case 50 may include a case body 52 and a support frame 53. Second quick-release fixing structure 51 may be placed on the back of case body 52 (the front may be used for holding load 60) . Support frame 53 may be rotatably connected to the back of case body 52. Support frame 53 may have a supporting state and a retracted state. When support frame 53 is in the supporting state, support frame 53 and case body 52 may form an angle. When support frame 53 is retracted, support frame 53 is attached to the back surface of case body 52. When load protection case 50 is detached from handle 10, support frame 53 may be used to support case body 52, and thus provide support to load 60.

Optionally, as shown in FIG. 11, second quick-release fixing structure 51 may be an annular boss, and groove 511 may be formed inside the annular boss. Support frame 53 may correspondingly be a ring structure, so that support frame 53 may be sleeved onto the outer circumference of the annular boss when stored. This facilitates the alignment of support frame 53 with second quick-release fixing structure 51, thereby reducing occupied space. When load protection case 50 is to mounted onto gimbal stabilizer 100, support frame 53 may be retracted and sleeved on the outer circumference of the annular boss. This design does not affect the interaction between second quick-release fixing structure 51 and first quick-release fixing structure 216.

In some embodiments, as shown in FIGs. 10-11, handle 10 may further include a third quick-release fixing structure 17, and load protection case 50 is then provided with a fourth quick-release fixing structure 54 for interacting with third quick-release fixing structure 17. By including an additional set of third quick-release fixing structure 17 and fourth quick-release fixing structure 54, attachment/detachment efficiency between load protection case 50 and handle 10 may be further improved.

Optionally, third quick-release fixing structure 17 may be placed at the position of mounting slot 16 on handle 10, or on the opposite side of mounting slot 16 on handle 10. When third quick-release fixing structure 17 is placed on mounting slot 16, there is no need to occupy other sidewalls of handle 10. In some embodiments, a remote control (an example operation unit 40) may be also mounted onto mounting slot 16 when third quick-release fixing structure 17 is not mounted.

In some embodiments, third quick-release fixing structure 17 may be a second boss. In some embodiments, the contour of fourth quick-release fixing structure 54 may match the contour of mounting slot 16, and fourth quick-release fixing structure 54 may include a groove 541 corresponding to the second boss, as shown in FIG. 11. When load protection case 50 is mounted onto gimbal stabilizer 100, the second boss and groove 541 may be interference fit, so as to achieve a quick attachment/detachment between third quick-release fixing structure 17 and fourth quick-release fixing structure 54. In some embodiments, the cross-sectional shape of the second boss may be similar to the cross-sectional shape of the first boss, which may be a conventional shape, such as a circle, a square, a triangle, etc., or an irregular shape. In some embodiments, as shown in FIG. 11, the cross-sectional shape of the second boss is circular, and groove 541 is a round groove.

FIG. 12 illustrates an application scenario of the handle and the load protection case according to an embodiment of the present disclosure. As shown in FIG. 12, when load protection case 50 is mounted onto handle 10, remote control 40 may be put at open end 11 of handle 10, which is convenient for a user to operate locally. Remote control 40 may also be separated from handle 10 (not shown in the figure) , so as to facilitate remote control by a user.

In some embodiments, support frame 53 may match fourth quick-release fixing structure 54. When support frame 53 is retracted, support frame 53 may be sleeved on fourth quick-release fixing structure 54. Alternatively, support frame 53 may cover fourth quick-release fixing structure 54. At this point, when fourth quick-release fixing structure 54 is to be attached to third quick-release fixing structure 17, support frame 53 may be removed from case body 52.

Additionally or alternatively, first quick-release fixing structure 216 may include a first magnet, and second quick-release fixing structure 51 may include a second magnet. First quick-release fixing structure 216 and second quick-release fixing structure 51 may be connected by an attraction force between the first magnet and the second magnet. This connection mode has a simple structure and is easy to disassemble.

EMBODIMENT 2

In some embodiments (Embodiment 2) , the present disclosure further provides another gimbal stabilizer 200. FIG. 13A illustrates a schematic diagram of an extended state of a gimbal stabilizer 200 according to Embodiment 2 of the present disclosure. As shown in FIG. 13A, gimbal stabilizer 200 may include a base 30, a first rotary electric motor 22, a second rotary electric motor 23, and an arm portion 21. Arm portion 21 may further include a first arm 211 and a second arm 212. One end (e.g., the lower end) of first arm 211 may be pivotally mounted on base 30 through first rotary electric motor 22. In Embodiment 2, first rotary electric motor 22 may be optionally mounted on base 30 through a connection element 301. First rotary electric motor 22 may be configured to drive first arm 211 to rotate around a first rotation axis 01 relative to base 30. First rotation axis 01 may, for example, parallel to the centerline of base 30. Second rotary electric motor 23 may be connected to the other end (e.g., the upper end) of first arm 211 through an articulated shaft 217. One end of second arm 212 may be connected to second rotary electric motor 23, to drive second arm 212 to rotate around a second rotation axis 02.

FIG. 14 illustrates a first folded state of the gimbal stabilizer according to Embodiment 2 of the present disclosure. FIGs. 15-17 respectively illustrate schematic diagrams of the gimbal stabilizer in a fully folded state according to Embodiment 2 of the present disclosure. As shown in FIG. 14, second arm 212 may rotate around articulated shaft 217 so as to switch between the first folded position and the unfolded position. As shown in FIGs. 15-17, when gimbal stabilizer 200 is further folded to a completely folded position, second arm 212 may maintain its folded state. First arm 211 may pull second arm 212 and together they may fold to a position adjacent to base 30. As a result, second arm 212 is close to first arm 211 and may flush with first arm 211. That is, in the completely folded position, both second arm 212 and second rotary electric motor 23 may be housed in a recess of first arm 211. Accordingly, first arm 211 may parallel to second arm 212, or an angle may exist between first arm 211 and second arm 212, where the angle may be nominal, for example, between 0°and 10°.

In some embodiments, as shown in FIGs. 13A-17, first arm 211 may be L-shaped. When second arm 212 rotates closer to first arm 211 around articulated shaft 217, second arm 212 may be in a first folding position, and second arm 212 may be stored in the recess of first arm 211, so that arm portion 21 can be folded into a very compact form for easy storage. Specifically, as shown in FIG. 13A, first arm 211 may include a horizontal section 2111 and a vertical section 2112. Horizontal section 2111 may be aligned in the horizontal direction, and vertical section 2112 may be aligned in the vertical direction. First rotary electric motor 22 may be installed in horizontal section 2111, and the output shaft of first rotary electric motor 22 may be vertically aligned. The housing of first rotary electric motor 22 may be fixedly connected to horizontal section 2111. The output shaft of first rotary electric motor 22 may be fixedly connected to base 30 through a connection element 301. First rotary electric motor 22 may drive first arm 211 to rotate around a first rotation axis 01. Vertical section 2112 may be connected to pitch bracket 213 through articulated shaft 217, so that pitch bracket 213 can rotate around articulated shaft 217 relative to first arm 211. Second arm 212 may include a roll bracket 214. One end of pitch bracket 213 may be connected to vertical section 2112 through articulated shaft 217, and the other end of pitch bracket 213 may be fixedly connected to the housing of second rotary electric motor 23. The output shaft of second rotary electric motor 23 may be fixedly connected to roll bracket 214. Second rotary electric motor 23 may be configured to drive roll bracket 214 to rotate around a second rotation axis 02 relative to pitch bracket 213, where second rotation axis 02 may be perpendicular to articulated shaft 217.

In some embodiments, as shown in FIG. 13A, gimbal stabilizer 200 may further include a third rotary electric motor 24. Third rotary electric motor 24 may be connected to the other end of second arm 212. Roll bracket 214 may be fixedly connected to the housing of third rotary electric motor 24. The output shaft of third rotary electric motor 24 may be fixedly connected to a load connection frame 215, and third rotary electric motor 24 may be configured to drive load connection frame 215 to rotate around a third rotation axis 03 relative to the roll bracket 214. Third rotation axis 03 and second rotation axis 02 may form an included angle there-between. Load connection frame 215 may be used to mount a load. The structure shown in FIG. 13A includes a first arm, a second arm, a first rotary electric motor, a second rotary electric motor, and a third rotary electric motor. The present disclosure is not limited thereto, and may also include more or fewer arms and rotary electric motors.

In some embodiments, as shown in FIG. 13A, first arm 211 may be hinged to base 30 through an articulated shaft 218. A rotation axis 04 of articulated shaft 218 may be perpendicular to a rotation axis of first rotary electric motor 22 (i.e., the first rotation axis 01) . In some implementations, first arm 211 may rotate around articulated shaft 218 relative to base 30 within a range of 180 degrees (FIGs. 13A and 15 illustrate two rotation positions of 0 and 180 degrees respectively) .

Similar to Embodiment 1, base 30 of gimbal stabilizer 200 in Embodiment 2 may also include a controller, a first battery, and a second battery, where the first battery may be configured to supply power to first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24, the controller may be configured to control first rotary electric motor 22, second rotary electric motor 23, and the third rotary electric motor 24. The second battery may be configured to charge the first battery. As shown in FIG. 13B, gimbal stabilizer 200 may further include a first charging interface and an operation unit (not shown) . The first charging interface may include a wireless charging module 14 that may be coupled to the second battery and configured to wirelessly charge a load. The operation unit, for example, may be mounted onto the surface of base 30 and is configured to control the operations of first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24 through the controller. In some embodiments, the operation unit is, for example, a remote control. For details, refer to the description of Embodiment 1, which will not be repeated here.

In some embodiments, wireless charging module 14 may be a part of the first charging interface, as shown in FIG. 13B. The first charging interface may be configured to charge the second battery, so as to charge a load coupled to the wireless charging interface. Optionally, wireless charging module 14 may include a transmitting coil 146 and a transmitting circuit board 145. Transmitting circuit board 145 may be electrically connected to second battery 18, and transmitting circuit board 145 may include control circuits and chips required for wireless charging. Transmitting coil 146 may be, for example, placed on transmitting circuit board 145 or electrically connected to transmitting circuit board 145. When a load is close to wireless charging module 14, transmitting circuit board 145 of wireless charging module 14 may receive electric energy from second battery 18. The electric energy may be converted into alternating current, which may be input to transmitting coil 146. After the alternating current is input to transmitting coil 146, a changing magnetic field may be generated. The coil in the load may induce a change in the magnetic field, and an induced current may be then generated, thereby achieving a charging of the load. FIG. 13B illustrates a situation where the first charging interface includes wireless charging module 14. However, the present disclosure is not limited thereto. In some embodiments, the first charging interface may include a wired charging solution. For example, a charging dock may be disposed on the outer surface of handle 10, where the charging dock may have a charging connector matching a charging interface of a load. When the load is docked, the load is charged.

In the foregoing embodiments, a load may be charged through the batter (ies) integrated into the handle of a gimbal stabilizer, which may provide users with great convenience, especially when a load is charged through wireless charging. In such a gimbal stabilizer, a user does not need to carry a separate charging device or power bank when going out to take pictures using a mobile phone or another electronic device.

In some embodiments, gimbal stabilizer 200 may further include a charging switch 19 (as shown in FIG. 3) disposed on handle 10. Charging switch 19 may be configured to turn on or off a charging of load 60 by second battery 18. As shown in FIG. 1, the stabilizer body may further include a first battery 33. First battery 33 may be configured to drive the stabilizer body to move.

In some embodiments, the handle may further include a second charging interface (not shown) located inside the accommodating space. The second charging interface may be connected to second battery 18. When the stabilizer body is placed in the accommodating space, first battery 33 may be electrically connected to second battery 18 through the second charging interface, so that the second battery 18 can charge first battery 33. Optionally, second battery 18 may be electrically connected to first battery 33 through the second charging interface, so that second battery 18 and first battery 33 may collectively charge load 60 coupled to the first charging interface. The second charging interface may be a wired charging interface or a wireless charging interface.

As described elsewhere herein, gimbal stabilizer 200 in Embodiment 2 may further include handle 10 (or the housing) , so that gimbal stabilizer 200 may be stored inside handle 10 after being folded. In addition, the features described with respect to handle 10 in Embodiment 1, including but are not limited to, the first locking element, second locking element, first battery, second battery, controller, wireless charging module, operation unit, fixed footpad, and movable footpads, the quick-release fixing structures, etc., may be also implemented in the technical solution of Embodiment 2 without creative spirits, all of which fall within the protection scope of the present disclosure.

In some embodiments, as shown in FIGs. 11-12, gimbal stabilizer 200 may further include a load protection case 50. Load protection case 50 may be configured to mount a load. Arm portion 21 may include a first quick-release fixing structure 216. A second quick-release fixing structure 51 for connecting with first quick-release fixing structure 216 may be placed on load protection case 50. Load protection case 50 may include a case body and a support frame. Second quick-release fixing structure 51 may be placed on the back of the case body, and the support frame may be rotatably connected to the back of the case body. The support frame may be in a supporting state and a retracted state. When the support frame is in a supporting state, the support frame may form an angle with the case body. When the support frame is retracted, the support frame may be attached to the case body on the back. Optionally, as shown in FIG. 11, second quick-release fixing structure 51 may be an annular boss, and the support frame may be a ring structure. When the support frame is retracted, the support frame may be sleeved on the outer circumference of the annular boss.

Additionally or alternatively, first quick-release fixing structure 216 may include a first magnet, and second quick-release fixing structure 51 may include a second magnet. First quick-release fixing structure 216 and second quick-release fixing structure 51 may be connected through an attraction force between the first magnet and the second magnet, and this connection method has a simple structure and is easy to attach/detach.

In some embodiments, as shown in FIGs. 11 and 13A, a third quick-release fixing structure 17 may be further provided on base 30. A fourth quick-release fixing structure 54 for connecting with third quick-release fixing structure 17 may be also disposed on load protection case 50. The inclusion of third quick-release fixing structure 17 and fourth quick-release fixing structure 54 may allow a quick attachment/detachment of load protection case 50 to/from handle 10, thereby improving the attachment/detachment efficiency.

EMBODIMENT 3

In some embodiments (e.g., Embodiment 3) , the present disclosure provides yet another gimbal stabilizer 300. FIG. 18 illustrates a schematic diagram of a gimbal stabilizer in a fully extended state according to Embodiment 3 of the present disclosure. As shown in the figure, gimbal stabilizer 300 may include a first arm 211, a first rotary electric motor 22, a second arm 212, and a second rotary electric motor 23. First rotary electric motor 22 may be installed at one end of first arm 211. One end (e.g., the lower end shown in the figure) of second arm 212 may be connected to first rotary electric motor 22, and may be driven by first rotary electric motor 22 to rotate. Second rotary electric motor 23 may be disposed at the other end of second arm 212 (e.g., the upper end shown in FIG. 18) .

In some embodiments, as shown in FIG. 18, gimbal stabilizer 300 may further include a third arm 223 and a third rotary electric motor 24. In some embodiments, third arm 223 may have two arms, as shown in FIG. 18. Each arm may be hinged to the exterior of third rotary electric motor 24, respectively. One end (e.g., the left end shown in FIG. 18) of the two third arms 223 may be connected to second rotary electric motor 23, and can be driven to rotate by second rotary electric motor 23. Third rotary electric motor 24 may be disposed at the other ends of the two third arms 223 (e.g., the right ends shown in FIG. 18) . Third rotary electric motor 24 may be connected to a load (not shown) .

FIG. 19 illustrates a schematic diagram of folding the second arm of gimbal stabilizer 300 according to an embodiment of the present disclosure. As shown in FIGs. 18-19, second arm 212 may be hinged to first rotary electric motor 22 through a hinge axis 201, so that second arm 212 can be driven by first rotary electric motor 22 to rotate around hinge axis 201. Hinge axis 201 may be perpendicular to a rotation axis 202 of first rotary electric motor 22. One ends of the two third arms 223 may be hinged to second rotary electric motor 23 and form a rotation axis 203, so that two third arms may be driven to rotate by second rotary electric motor 23 around rotation axis 203. Rotation axis 203 may be perpendicular to a rotation axis 204 of the second rotary electric motor. The other ends of the two third arms 223 may be hinged to third rotary electric motor 24 and form a rotation axis 205, so that third rotary electric motor 24 may rotate around rotation axis 205. The third rotary electric motor may also have a rotation axis 206 (shown more clearly in FIGs. 20-21) , so that a load mounted on the third rotary electric motor may be driven to rotate around rotation axis 206.

FIG. 20 illustrates a schematic diagram of folding the second arm and the third arm according to Embodiment 3 of the present disclosure. FIG. 21 illustrates a schematic diagram of folding the first arm according to Embodiment 3 of the present disclosure. When second arm 212 and third arm 223 are to be folded, for example, starting from the state shown in FIG. 18, first rotary electric motor 22 may be first actuated, so that second arm 212 may rotate around rotation axis 202 to a rear end position (e.g., the position shown in FIG. 19) of first arm 211. Then a rotation of third arm 223 around a rotation axis 203 may pull second rotary electric motor 23, so that second rotary electric motor 23 and third rotary electric motor 24 may be placed in a same plane (e.g., the position shown in FIG. 20) . At this point, third arm 223 and second arm 212 may parallel, and first arm 211 may be perpendicular to second arm 212. Next, rotate second arm 212 (together with third arm 223, second rotary electric motor 23, and third rotary electric motor 24) around rotation axis 201 (as shown in FIG. 18) , so that first arm 211 and second arm 212 may parallel (e.g., positions as shown in FIG. 21) . At this point, first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24 may be approximately located in a same plane.

As shown in FIG. 21, the length of second arm 212 may approximately equal to the sum of the lengths of first arm 211 and third arm 223. That is, the length of second arm 212 may be the same as the sum of the length of first arm 211 and the length of third arm 223. Optionally, the length of second arm 212 may also be slightly larger than the sum of the lengths of first arm 211 and third arm 223, so that first arm 211 and third arm 223 may be folded within the length of second arm 212. As shown in FIGs. 20-21, gimbal stabilizer 300 may further include a housing 35. Housing 35 may have an accommodating space, and first arm 211 is hinged to housing 35 and may be able to rotate around a hinge axis 207 relative to housing 35.

FIGs. 22A-22B illustrate schematic diagrams of an internal structure of the storage state of the gimbal stabilizer according to Embodiment 3 of the present disclosure. FIGs. 23A-23B illustrate schematic diagrams of the storage state of the gimbal stabilizer according to Embodiment 3 of the present disclosure. Gimbal stabilizer 300 may be in an extended state and a storage state. As shown in FIG. 18, in the extended state, first arm 211, second arm 212, and third arm 223 may be located outside housing 35 and may be connected to housing 35. As shown in FIGs. 22A-23B, in the storage state, first arm 211, second arm 212, and third arm 223 may be stored in the accommodation space. Specifically, referring to FIGs. 21 and 22B, first arm 211, second arm 212, and third arm 223 together with first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24 may be arranged in a row in a direction perpendicular to hinge axis 207 in the accommodation space. First arm 211, second arm 212, third arm 223, first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24 previously protruding out of housing 35 may be all stored in the accommodating space of housing 35. This storage method may have a better usage of the volume of the accommodating space, and very cleverly combine all the motors (e.g., first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24) and all the arms (e.g., first arm 211, second arm 212, and third arm 223) into a same accommodating space. This greatly reduces the overall size of the gimbal stabilizer and improves space utilization. The structure shown in FIG. 18 includes a first arm, a second arm, a third arm, a first rotary electric motor, a second rotary electric motor, and a third rotary electric motor. However, the present disclosure is not limited thereto, and may also include more or fewer arms and the rotary electric motors, all of which shall fall into the protection scope of the present disclosure.

In some embodiments, gimbal stabilizer 300 may also include a battery 36 and a controller (not shown) , as shown in FIG. 21. Battery 36 may be configured to provide power to first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24, and the controller may be configured to control first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24.

In some embodiments, housing 35 may further include a wireless charging module (not shown) . The wireless charging module may be coupled to battery 36 and configured to wirelessly charge a load mounted on housing 35. Optionally, the wireless charging module may be disposed, for example, on the back of housing 35 shown in FIGs. 22A and 23A.

In some embodiments, gimbal stabilizer 300 may also include a battery connector (not shown) connected to battery 36. The battery connector may be connected to an external power adaptor for charging the battery. The battery connector may be a Micro USB, Type-C,

connector, or any other connector for connecting to a power adaptor. The port of the battery connector may be located on the external surface of housing 35 at different locations, e.g., on the side, on the back, or in the front, or any other proper location of housing 35. When connected to a power adaptor, battery 36 may be charged, either when gimbal stabilizer 300 is in an extended state and a storage state. In some embodiments, a load (e.g., a cellphone) mounted on housing 35 may be further charged through the aforementioned wireless charging module. In this way, the connected power adaptor may charge both gimbal stabilizer 300 and an amounted load simultaneously, or only charge one of the two. In some embodiments, although not specifically described,

gimbal stabilizer

100 or 200 may also include a battery connector for connecting a battery with an external power adaptor, so as to charge the gimbal stabilizer and/or a load mounted on

gimbal stabilizer

100 or 200.

In some embodiments, as shown in FIGs. 23A-23B, gimbal stabilizer 300 may further include an operation unit 40 configured to control the operations of first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24 through a controller. Optionally, operation unit 40 may be a remote control, which may be detachably attached to housing 35.

In some embodiments, as shown in FIGs. 21-22A, gimbal stabilizer 300 may further include a cover 37, which may be hinged to housing 35. Cover 37 may be able to cover the accommodating place when gimbal stabilizer 300 is in the storage state, as shown in FIGs. 23A-23B. In some embodiments, operation unit 40 may be attached to cover 37. In some embodiments, operation unit 40 may be attached to the back side of housing 35 instead.

FIG. 24 illustrates a schematic diagram of a third rotary electric motor according to Embodiment 3 of the present disclosure. FIG. 25 illustrates a schematic diagram of a load protection case according to Embodiment 3 of the present disclosure. The interaction between a load and the gimbal stabilizer may be similar to those described above for gimbal stabilizer 100, details of which will not be repeated here.

EMBODIMENT 4

In some embodiments (Embodiment 4) , the present disclosure provides still another gimbal stabilizer 400. FIG. 26 illustrates a schematic diagram of an unfolded position of a gimbal stabilizer 400 according to Embodiment 4 of the present disclosure. FIGs. 27A-27B illustrate exploded views of a gimbal stabilizer according to Embodiment 4 of the present disclosure. As shown in FIGs. 26-27B, gimbal stabilizer 400 may include a handle 10, a first rotary electric motor 22, a second rotary electric motor 23, and a first arm 211. Handle 10 may have an accommodating space 101 inside the handle, as shown in FIG. 26. First rotary electric motor 22 may be fixedly installed on handle 10, for example, on one end of handle 10. First arm 211 may include a first arm body 310, a first rotation shaft 311, and a second rotation shaft 312. One end of first arm body 310 may be connected to first rotary electric motor 22 through first rotation shaft 311, so that first arm body 310 may be driven to rotate by the rotation of first rotary electric motor 22 around an axis 401. The other end of first arm 211 may be connected to second rotary electric motor 23 through a second rotation shaft 312.

FIG. 28 illustrates a schematic diagram of a folded state of a gimbal stabilizer according to Embodiment 4 of the present disclosure. Gimbal stabilizer 400 may have an unfolded state and a folded state. As shown in FIGs. 26 and 28, first arm body 310 may rotate around first rotation shaft 311. First rotation shaft 311 may be perpendicular to axis 401 of first rotary electric motor 22, to allow first arm 211 to switch between a folded position and an unfolded position. In the unfolded position, as shown in FIG. 26, first arm 211, first rotary electric motor 22, and second rotary electric motor 23 may be located outside handle 10 and connected to handle 10. For example, when gimbal stabilizer 400 operates in the unfolded position, a load may be connected to second rotary electric motor 23 and stably supported and driven by second rotary electric motor 23. The load may be an electronic device such as a mobile phone, tablet, and camera, etc. In the folded position, first arm 211 and second rotary electric motor 23 may be at least partially stored in the accommodating space. As shown in FIG. 28, first arm body 310 may be moved into the opening area of accommodating space 101 of handle 10 through folding, so that second rotary electric motor 23 may be stored in the accommodating space. Gimbal stabilizer 400 may be in a storage state. By accommodating second rotary electric motor 23 in the accommodating space, the overall size of gimbal stabilizer 400 is reduced, and it is convenient to carry. Gimbal stabilizer 400 may be freely switched between a folded state and an unfolded state as needed. Specifically, when gimbal stabilizer 400 is used, second rotary electric motor 23 may be unfolded from the accommodating space. For example, first arm body 310 may be unfolded so that first arm 211 may move from a position close to the opening area of the accommodating space of handle 10 towards a position away from the opening area of the accommodating space of handle 10. This allows second rotary electric motor 23 to have enough space to connect and support a load. When gimbal stabilizer 400 is not in use, folding first arm 2110 may allow second rotary electric motor 23 to be stored in the accommodating space.

In some embodiments, first rotation shaft 311 and second rotation shaft 312 may not be rotatable by themselves. Taking first rotation shaft 311 as an example, in some embodiments, first rotation shaft 311 itself may be fixed to the first rotary electric motor 22 and housing 102. For instance, first rotation shaft 311 may be fixed to the output part (e.g., the output shaft) of first rotary electric motor 22. Accordingly, first arm body 310 may pivot or rotate around first rotation shaft 311. In some embodiments, first rotation shaft 311 and first arm body 310 may be non-rotatable with respect to each other. In addition to being driven to rotate around axis 401 by first rotary electric motor 22, first rotation shaft 311 and first arm body 310 may also rotate together around the longitudinal axis of first rotation shaft 311. In some embodiments, second rotation shaft 312 and first arm body 310 may also be non-rotatable with respect to each other. In addition to being driven to rotate around axis 402 by first rotary electric motor 23, second rotation shaft 312 and first arm body 310 may also rotate together around the longitudinal axis of second rotation shaft 312.

Optionally, first rotation shaft 311 and second rotation shaft 312 may be a hollow shaft, which further reduces the weight of gimbal stabilizer 400, which makes the gimbal stabilizer lighter and more portable.

In some embodiments, as shown in FIGs. 26-27A, gimbal stabilizer 400 may further include a second arm 32 and a third rotary electric motor 24. Second arm 32 is shown to have two arms in the figure. One ends of second arms 32 may be connected to second rotary electric motor 23, so that second rotary electric motor 23 may drive second arms 32 to rotate around an axis 402 of second rotary electric motor 23. The other ends of second arms 32 may be connected to the outside of third rotary electric motor 24, which may be configured to rotate about its axis 403, to drive a load mounted onto the second arms.

In some embodiments, the diameter of first rotary electric motor 22 may be set to a predefined value (e.g., a value between 20-24 mm) , and the of height first rotary electric motor 22 may be set to another value (e.g., a value between 18-24 mm) . Second rotary electric motor 23 and third rotary electric motor 24 may have a same diameter and height, and the diameter may be set to 22-28 mm and the height may be set to 15-20 mm. The structure shown in FIGs. 27A-27B may include a first arm, a second arm, a first rotary electric motor, a second rotary electric motor, and a third rotary electric motor. The present disclosure is not limited thereto, and may include more or fewer arms and rotary electric motors.

In some embodiments, as shown in FIGs. 26-27A, one end of second arm 32 may be connected to second rotary electric motor 23 through a third rotation shaft 313. Third rotation shaft 313 may be perpendicular to axis 402 of second rotary electric motor 23. Second arm 32 and third rotary electric motor 24 may rotate together around third rotation shaft 313. As shown in FIGs. 26-27A, second arm 32 may have a double-arm structure (e.g., upper and lower arms) , where the two arms may merge in the middle. The two arms may respectively have through holes on the left, through which third rotation shaft 313 may pass. Third rotation shaft 313 may also pass through second rotary electric motor 23. Therefore, second arm 32 may rotate relative to second rotary electric motor 23 around third rotation shaft 313. The right side of second arm 32 may be fixedly connected to third rotary electric motor 24. Optionally, the structure of third rotation shaft 313 may be a hollow shaft, which further reduces the weight of gimbal stabilizer 400 to make the gimbal stabilizer lighter and more portable.

In some embodiments, as shown in FIG. 28, second rotary electric motor 23 may rotate around second rotation shaft 312, and may be driven to rotate around its own axis 402, so that third rotary electric motor 24 and second rotary electric motors 23 may be aligned in parallel. The alignment of third rotary electric motor 24 and second rotary electric motor 23 in parallel may be the arrangement shown in FIG. 27B or the arrangement shown in FIG. 28. As shown in FIG. 27B, third rotary electric motor 24 may rotate around an axis 403 of the third rotary electric motor, to allow axis 403 to be collinear with axis 402 of second rotary electric motor 23. Alternatively, by rotating second arm 32 around third rotation shaft 313, axis 403 of third rotary electric motor 24 may parallel to axis 402 of second rotary electric motor 23. When gimbal stabilizer 400 is switched to a folded position, second arm 32 and third rotary electric motor 24 may be rotated around third rotation shaft 313, so that axis 403 of third rotary electric motor 24 is in parallel with axis 402 of second rotary electric motor 23. Next, second rotary electric motor 23 may be driven to rotate, so that second arm 32 and third rotary electric motor 24 may rotate together around axis 402 of second rotary electric motor 23, as shown in FIGs. 26-27A in a vertical arrangement (second rotary electric motor 23 is at the top and third rotary electric motor 24 is at the bottom) . Next, second rotation shaft 312 may be rotated, so that second rotary electric motor 23 and third rotary electric motor 24 may be both roughly located in a same plane as housing 102. Next, first arm 211 may be rotated around first rotation shaft 311, so that third rotary electric motor 24 is in parallel with second rotary electric motor 23, and the two may be then stored in the accommodating space, as shown in FIG. 28.

In some embodiments, as shown in FIGs. 27A-27B, handle 10 may also be provided with a battery 71 and a controller (not shown in the figure) . Battery 71 may be configured to provide power to first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24, and the controller may be configured to control the operations of first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24. By putting battery 71 and the controller inside handle 10 may allow the structure more compact, and thus save space in assembly. The controller may optionally be a PCB circuit board on which corresponding chips or circuits are integrated, and are electrically connected to first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24. In FIGs. 27A-27B, battery 71 is shown as being located outside housing 102. In some embodiments, battery 71 may be integrated inside housing 102, for example, located at an area above the accommodating space 101.

In some embodiments, as shown in FIG. 27A, handle 10 may include a wireless charging module 72, which may be coupled to battery 71 and configured to wirelessly charge a load. In some embodiments, gimbal stabilizer 400 may also include a power connector for connecting battery 71 with an external power adaptor, so as to charge gimbal stabilizer 400 and/or a load mounted on gimbal stabilizer 400.

FIG. 29 illustrates a schematic diagram of an operation unit according to Embodiment 4 of the present disclosure. As shown in FIGs. 28-29, gimbal stabilizer 400 may further include an operation unit 40 configured to control operations of first rotary electric motor 22, second rotary electric motor 23, and third rotary electric motor 24 through the controller. Optionally, operation unit 40 may be detachably attached to handle 10, and wirelessly connect and communicate with first rotary electric motor 22, second rotary electric motor 23, third rotary electric motor 24, and the load for remote control. As shown in FIG. 29, operation unit 40 may be fixedly mounted on handle 10, which is convenient for a user to operate locally. In some embodiments, operation unit 40 may be a remote control, which is detachably attached to handle 10. That is, the remote control may be removed from handle 10 to allow a user to control remotely.

In some embodiments, as shown in FIG. 27A, gimbal stabilizer 400 may further include movable footpad (s) 110. Optionally, there are two movable footpads 110-1 and 110-2 respectively. The two movable footpads 110-1 and 110-2 may be both disposed in a groove at the bottom of handle 10, and support gimbal stabilizer 400 when they spread out. Specifically, when the two movable footpads 110-1 and 110-2 spread out from the groove at the bottom of handle 10, the two movable footpads 110-1 and 110-2 may rotate around a center, to provide vertical and stable support of handle 10, so as to keep handle 10 stably standing on a desktop or another platform (such as the surface of a car dashboard) . When the two movable footpads 110-1 and 110-2 are retracted, the two movable footpads 110-1 and 110-2 may be placed into the groove at the bottom of handle 10.

FIG. 30 illustrates a schematic diagram of a third rotary electric motor according to Embodiment 4 of the present disclosure. FIG. 31 illustrates a schematic diagram of a load protection case according to Embodiment 4 of the present disclosure.

In some embodiments, as shown in FIG. 30, third rotary electric motor 24 may include a load connection frame 231, where load connection frame 231 may be fixedly connected to the output shaft of third rotary electric motor 24. Third rotary electric motor 24 may be configured to drive load connection frame 231 to rotate around axis 403. Load connection frame 231 may be used for holding a load. As shown in FIG. 31, gimbal stabilizer 400 may further include a load protection case 50, which may be configured to mount a load.

In some embodiments, as shown in FIGs. 30-31, first quick-release fixing structure 232 may be disposed on third rotary electric motor 24. A second quick-release fixing structure 51 for connecting to first quick-release fixing structure 232 may be disposed on load protection case 50. Through the interaction between first quick-release fixing structure 232 and second quick-release fixing structure 51, load protection case 50 may be quickly attached to or detached from third rotary electric motor 24.

In some embodiments, first quick-release fixing structure 232 and second quick-releasing fixing structure 51 may have a similar structure and function as described above for gimbal stabilizer 100. In some embodiments, as shown in FIG. 28, handle 10 of gimbal stabilizer 400 may be provided with a third quick-release fixing structure 234, and load protection case 50 may be also provided with a fourth quick-release fixing structure 54 for connecting with third quick-release fixing structure 234. The structure and function of third quick-release fixing structure 234 and fourth quick-release fixing structure 54 may be similar to those described above for

gimbal stabilizer

100 or 200.

In some embodiments, another different load protection case is also provided in the present disclosure. As shown in FIGs. 32A-32B, a load protection case 600 for mounting and protecting a load may include a case body 61, a second quick-release fixing structure 62 and a support frame 63. The load, such as a mobile phone, may be mounted and fixed to case body 61. Second quick-release fixing structure 62 may be disposed on the back of case body 61 for attaching to first quick-release fixing structure 232. In some embodiments, a snap-in plug (not shown) may be also provided on the back of second quick-release fixing structure 62. Through the interaction between first quick-release fixing structure 232 and second quick-release fixing structure 62, load protection case 600 may be quickly attached to or detached from third rotary electric motor 24.

In some embodiments, first quick-release fixing structure 232 may be an annular groove (not shown) . As shown in FIG. 33, second quick-release fixing structure 62 may include a boss 622 corresponding to the annular groove. When load protection case 600 is mounted on gimbal stabilizer 400, the groove and boss 622 may be interference fit, to allow a quick release of second quick-release fixing structure 62 from first quick-release fixing structure 232. Optionally, the cross-sectional shape of boss 622 may be a regular shape such as a ring, a circle, a square, a triangle, etc., or an irregular shape. Optionally, as shown in FIG. 33, the cross-sectional shape of boss 622 may be circular, and the corresponding groove may be a round groove. In some embodiments, the groove of the first quick-release fixing structure 232 may further include a protrusion (not shown) , and second quick-release fixing structure 62 may further include a groove 621 matching the protrusion (shown more clearly in FIG. 32B) . Accordingly, when load protection case 600 is mounted onto gimbal stabilizer 400, the alignment and attachment of protection case 600 can be achieved more accurately and quickly due to the interference fit connection between boss 622 and groove 621.

In some embodiments, as shown in FIGs. 32A-32B, support frame 63 may be rotatably connected to the back of case body 61. Support frame 63 may have a supporting state and a retracted state. When support frame 63 is in the supporting state, support frame 63 may form an angle with case body 61. When support frame 63 is retracted, support frame 63 may be attached to the back of case body 61. When load protection case 600 is not connected to third rotary electric motor 24, support frame 63 may provide support to case body 61, thereby supporting the load.

Optionally, as shown in FIGs. 32A-32B, support frame 63 may be a ring-shaped structure corresponding to boss 622, so that support frame 63 can be sleeved on the outer circumference of boss 622 when stored. This may facilitate alignment between support frame 63 and second quick-release fixing structure 62, so as to reduce occupied space. When load protection case 600 is mounted onto gimbal stabilizer 400, support frame 63 may be retracted and sleeved on the outer circumference of boss 622, which then does not affect the interaction between second quick-release fixing structure 62 and first quick-release fixing structure 232. In some embodiments, as shown in FIG. 32B, support frame 63 may be a ring buckle, which may be fixed to second quick-release fixing structure 62 through its shaft, so as to provide support to a load like a cell phone.

In some embodiments, as shown in FIGs. 32A-32B, load protection case 600 may further include a guide portion 64. Guide portion 64 may be disposed on case body 61, and an elongated groove 641 matching second quick-release fixing structure 62 may be provided inside guide portion 64. This may allow second quick-release fixing structure 62 to freely slide within elongated groove 641 relative to a load. At least two holding positions may be configured on guide portion 64, namely a first preset holding position 642 and a second preset holding position 643. First preset holding position 642 may be configured at the center of the back of a load (e.g., the rightmost side of elongated groove 641 as shown FIGs. 32A-32B) . Second preset holding position 643 may be configured on the leftmost side of elongated groove 641. In addition, at the non-groove portion of guide portion 64, in the positions corresponding to first preset holding position 642 and second preset holding position 643, a buckle that matches a card slot of second quick-release fixing structure 62 may be disposed at these positions, so as to hold second quick-releasing fixing structure 62 at these positions. As shown in FIG. 33, when second quick-release fixing structure 62 is attached to gimbal stabilizer 400, second quick-release fixing structure 62 may be slid to first preset holding position 642, so as to hold second quick-release fixing structure 62 at first preset holding position 642 through the interaction between the buckle and the card slot. When the load performs some other functions, such as wireless charging, to free the space, second quick-release fixing structure 62 may be slid to second preset holding position 643, so as to hold second quick-release fixing structure 62 at second preset holding position 643 through the interaction between the buckle and the card slot.

Similarly, according to an embodiment of the present disclosure, first quick-release fixing structure 232 may include a first magnet, and second quick-release fixing structure 62 may include a second magnet. First quick-release fixing structure 232 and second quick-release fixing structure 62 may be connected through the attraction force between the first magnet and the second magnet. The first magnet and the second magnet may be made of steel or other magnetically conductive materials. This connection method has a simple structure and is easy to detach.

In various gimbal stabilizers described above in Embodiment 1-Embodiment 4, to prevent misalignment between a transmitting coil in a wireless charging interface and a coil in a load during a wireless charging process, in some embodiments, different positioning mechanisms may be further applied, to improve the alignment between the transmitting coil in a wireless charging interface and the coil in a load. For instance, to facilitating the alignment between the transmitting coil in the wireless charging interface and the coil in a load, a first/third quick-release fixing structure on a gimbal stabilizer and a second/fourth quick-release fixing structure on a load protection case may be designed to serve as a part of a positioning mechanism to position the transmitting coil, so as to align the transmitting coil with the coil in a load for improved wireless charging. For instance, the first/third quick-release fixing structure and the second/fourth quick-release fixing structure may be positioned at locations corresponding to the transmitting coil and the coil in a load, respectively. For example, in FIGs. 34A-34B, a first/third quick-release fixing structure 421 may be positioned in a location corresponding to a transmitting coil 423 in a gimbal stabilizer. Although not shown, the second/fourth quick-release fixing structure on a load protection case may be positioned in a location corresponding to a coil in a load. Accordingly, when the load protection case is attached to the gimbal stabilizer through the first/third quick-release fixing structure and the second/fourth quick-release fixing structure, transmitting coil 423 in the wireless charging interface in the gimbal stabilizer may be aligned well with the coil in a load (e.g., a cell phone, a tablet, etc. ) .

In some embodiments, to prevent misalignment caused by the impact of external force, one or more additional magnets may be further included in the wireless charging interface or in other locations of a gimbal stabilizer. Correspondingly, a same number of magnets may be also disposed on the load protection case. These magnets may be located away from the locations corresponding to the transmitting coil and the coil in a load. FIGs. 34A-34B further show a magnet 422 located on the right side of transmitting coil 423 in the gimbal stabilizer. Although not shown, the load portion case may also have a magnet in a corresponding location. By including the additional magnets, an accurate and firm positioning and fixation under the wireless charging state may be achieved, thereby allowing a stable and efficient wireless charging process. As shown in FIGs. 34A-34B, since magnet 422 is located inside the housing of a gimbal stabilizer, the exterior design of a gimbal stabilizer does not need a change, which may improve the appearance of the gimbal stabilizer.

It is to be noted, magnetic suction is merely one method among many fixing methods for improved alignment. If space is allowed, multiple magnets, instead of only one magnet, may be applied to achieve a more stable multi-point magnetic adsorption. In addition, there are many other methods, including vacuum suction, Velcro, straps, elastic buckles, etc., all of which can be applied to achieve fixed use requirements under wireless charging. These methods may be matched with a load’s appearance, materials, etc., to ensure beautiful appearance, convenient use, and bring a good experience to users.

The above-described gimbal stabilizers in various embodiments show certain advantages. For instance, a folding structure of an arm, a hollow structure of a handle, a base provided with a controller and a battery allow achievement of smaller storage space. A detachable load protection case is set to reduce the overall size of a gimbal stabilizer after storage. Compared with traditional stabilizers, the disclosed gimbal stabilizers have more functional support and support multiple application scenarios. In a storage state, the arm and base may be stored inside a handle to protect the arm, to avoid damage to the motors during daily carrying, and increase the service life of a gimbal stabilizer. A detachable remote control may allow remote control of a load or arm through a wireless connection. A handle is provided with movable footpads that can be opened and closed, and the structure of the handle and load protection case may be configured to expand more application scenarios. A handle is provided with an installation slot to meet the operation requirements of remote control in different positions. The disclosed gimbal stabilizer is not limited to these advantages and other advantages will become obvious in actual applications.

Although the present disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art can make modifications without departing from the protection scope of the present disclosure. It should be noted that the features in the embodiments of the present disclosure may be combined with each other without conflict. For example, certain features of one embodiment can be added to or used to modify another embodiment, without departing from the protection scope of the present disclosure.

The above description is merely for some embodiments of the present disclosure, and is not intended to limit the present disclosure. Any modification, equivalent replacement, improvement, etc., made within the spirit and principles of the present disclosure shall be included in the scope of protection of the present disclosure.
