Detailed Description

The stabilizer will be further described with reference to the drawings and specific examples.

Referring to fig. 2,3 and 4, the stabilizer 10 of an embodiment includes a handle 100, a first driving device 200, a second driving device 300, a third driving device 400 and a clamping assembly 500. The handle 100 is used for being held by a user, the clamping assembly 500 is used for fixing a photographing apparatus, such as a mobile phone, a camera, etc., and the first driving device 200, the second driving device 300 and the third driving device 400 cooperate to realize stable and multi-angle photographing of the photographing apparatus.

Specifically, the first driving device 200 includes a first fixing portion 210 and a first rotating portion 220 that are connected to each other, the first fixing portion 210 is connected to the handle 100, the first rotating portion 220 is rotatable relative to the first fixing portion 210, and an axis of the first rotating portion 220 extends along a first direction.

The second driving device 300 includes a second fixing portion 310 and a second rotating portion 320 connected to each other, and the second fixing portion 310 is connected to the first rotating portion 220, that is, the second driving device 300 can rotate together with the first rotating portion 220. The second rotating portion 320 is rotatable relative to the second fixing portion 310, and an axis of the second rotating portion 320 extends along a second direction, which is perpendicular to the first direction.

The third driving device 400 includes a third fixing portion 410 and a third rotating portion 420 connected to each other, and the third fixing portion 410 is connected to the second rotating portion 320, that is, the third driving device 400 can rotate together with the second rotating portion 320. The third rotating portion 420 is rotatable relative to the third fixed portion 410, and an axis of the third rotating portion 420 extends along a third direction, and the third direction is perpendicular to the second direction.

The three driving devices are all motors, the fixed part is a stator of the motor, and the rotating part is a rotor of the motor. The rotating part can rotate 360 degrees relative to the fixed part, and the rotating part can automatically rotate under the electric control action, and can be driven to rotate by external force (such as hand stirring) under the state that the motor is closed.

The clamping assembly 500 is connected to the third rotating part 420 such that any one of the first, second and third rotating parts 220, 320 and 420 rotates, and the clamping assembly 500 rotates together to achieve multi-angle photographing. The clamping assembly 500 includes an open end 510 and a closed end 520 disposed opposite to each other, and the open end 510 is configured to be penetrated by a photographing apparatus.

The stabilizer 10 of the present embodiment is foldable, so that the carrying volume of the stabilizer 10 can be reduced. Moreover, when the stabilizer 10 is in the folded state, the open end 510 faces the handle 100, and the first direction is perpendicular to the third direction, that is, when the stabilizer 10 is in the folded state, the axes of the first driving device 200, the second driving device 300 and the third driving device 400 are perpendicular to each other, which further reduces the volume of the stabilizer 10, and makes the stabilizer 10 more portable. In contrast, the conventional triaxial stabilizer cannot achieve this due to the problem of the motion dead point (the axis of the motor 3 coincides with the axis of the motor 1 when the clamping member 4 in fig. 1 faces the handle, and the axis of the motor 3 coincides with the axis of the motor 1, which may cause the program disorder, and thus the axis of the motor 3 coincides with the axis of the motor 1 is the motion dead point of the conventional triaxial stabilizer).

To further reduce the volume of the stabilizer 10, in the present embodiment, the axis of the second rotating portion 320 intersects with the axis of the third rotating portion 420, so that the length of the connection between the second driving device 300 and the third driving device 400 can be maximally reduced. It is understood that in other embodiments, the axis of the second rotating portion 320 and the axis of the third rotating portion 420 are different planes, and the distance between the axis of the second rotating portion 320 and the axis of the third rotating portion 420 is greater than 0cm and less than or equal to 2cm. That is, the axis of the second rotating portion 320 is spatially offset from the axis of the third rotating portion 420 by a distance.

The stabilizer 10 further includes an extension arm 600 connected to the first rotating part 220, the extension arm 600 having a shape matching that of the handle 100. The handle 100 is provided with a first cavity, the first fixing portion 210 is located in the first cavity, the extension arm 600 is provided with a second cavity, the first rotating portion 220 and the second driving device 300 are located in the second cavity, and the extension arm 600 not only can protect the second driving device 400, but also can be matched with the handle 100 to enable the stabilizer 10 to be more attractive.

The first housing 120 protrudes from one side of the handle 100, a portion of the first fixing portion 210 is located in the first housing 120, the second housing 620 matching the first housing 120 protrudes from one side of the extension arm 600, and a portion of the first rotating portion 220 is located in the second housing 620. When the stabilizer 10 is in the folded state, the first housing 120 is docked with the second housing 620, and the clamping assembly 500 is engaged with the second housing 620 to prevent the stabilizer 10 from being scattered.

In terms of control of the three driving devices, the stabilizer 10 of the present embodiment further includes a motion detection device 700 and a control center. The motion detection device 700 is a gyroscope that is connected to the control center and is capable of sending changes in azimuth to the control center. The control center is connected to the first driving device 200, the second driving device 300, and the third driving device 400, respectively, and can control the rotation angle of the first rotating part 220, the rotation angle of the second rotating part 320, and the rotation angle of the third rotating part 420 according to the result transmitted from the motion detection device 700.

Specifically, the control center includes a first sub-plate 810, a second sub-plate 820, and a third sub-plate 830. The first sub-plate 810 is connected to the first driving device 200, and can control the angle at which the first rotating part 220 rotates. The second sub-plate 820 is connected to the second driving device 300 and is capable of controlling the angle at which the second rotating portion 320 rotates. The third sub plate 830 is connected to the third driving device 400, and can control the rotation angle of the third rotation part 420. In this embodiment, each sub-plate is connected to the corresponding driving device by an electric wire.

In using the stabilizer 10, the clamping assembly 500 is manually deployed (assuming the deployed state of fig. 3) and the photographing apparatus is clamped into the clamping assembly 500. Next, the stabilizer 10 is activated (the stabilizer 10 is energized), and the first driving device 200, the second driving device 300, and the third driving device 400 can adjust the position of the photographing apparatus according to the manner in which the user holds the handle 100, so that the entire stabilizer 10 is in a balanced state, and at this time, the lens of the photographing apparatus faces the face of the user. It is assumed that in this equilibrium state, the position of the photographing apparatus is the initial position. In the use process, if the user changes the azimuth of the handle 100, the azimuth of the axis of the motion detection device 700 will also change, meanwhile, the motion detection device 700 will send the azimuth change signal to the first auxiliary plate 810, the second auxiliary plate 820 and the third auxiliary plate 830, the first auxiliary plate 810, the second auxiliary plate 820 and the third auxiliary plate 830 can calculate the rotation angle of the first rotation part 220, the rotation angle of the second rotation part 320 and the rotation angle of the third rotation part 420 according to the algorithm, and the rotation direction of the first rotation part 220, the rotation direction of the second rotation part 320 and the rotation direction of the third rotation part 420 are opposite to the corresponding directions of the azimuth of the axis of the motion detection device 700. In this way, the stabilizer 10 is always in the initial position even when moving, so that the stability of photographing can be ensured.

Of course, the user can also actively decide the shooting angle of the shooting device.

Specifically, the stabilizer 10 further includes a key assembly 840 and a main board 850, where the key assembly 840 is connected to the main board 850, and is capable of sending an action command to the main board 850, and the main board 850 is connected to the first driving device 200, the second driving device 300, and the third driving device 400, respectively, and is capable of controlling the rotation angle of the first rotating portion 220, the rotation angle of the second rotating portion 320, and the rotation angle of the third rotating portion 420 according to the action command.

In this embodiment, the motherboard 850 and the photographing device are wirelessly connected by bluetooth communication, and the key assembly 840 includes a power key 842, a rocker key 844, and a function key 846. The power key 842 is used to control the switching of the stabilizer 10 and is responsible for switching the photographing and image capturing functions of the photographing apparatus. The rocker key 844 is used to control the orientation of the photographing apparatus, such as pitch, roll, and heading of the photographing apparatus. The function keys 846 are provided in plural, some for adjusting the focal length of the photographing apparatus, some for changing the screen direction of the photographing apparatus, i.e., the horizontal and vertical photographing of the photographing apparatus, and some for controlling the operation modes of the respective driving devices, such as the lock and follow modes. It will be appreciated that in other embodiments, the motherboard 850 and the photographing device may be wired through wires, and the number of keys included in the key assembly 840 and the functions of each key may be determined according to the actual situation.

As shown in fig. 4, the stabilizer 10 further includes a battery 900 disposed in the handle 100, the battery 900 is connected to the main board 850, and the battery 900 can provide electric power to the main board 850 and thus to the first driving device 200, the second driving device 300, and the third driving device 400.

The third rotating portion 420 is provided with an interface 422, and the interface 422 is used for connecting the photographing device with the battery 900 to charge the photographing device, so as to ensure sufficient electric quantity of the photographing device.

The battery 900 is a rechargeable battery, and when the electric quantity is insufficient, the battery 900 can be charged through the interface.

As shown in fig. 5 and 6, the clamping assembly 500 further includes a first clamping plate 530, an attachment plate 540, and a second clamping plate 550, wherein the first clamping plate 530 is connected to the third rotating portion 420, the attachment plate 540 forms a closed end 520, one end of the attachment plate 540 is connected to the first clamping plate 530, the other end is movably connected to the second clamping plate 550, and the second clamping plate 550 can be close to or far from the first clamping plate 530 relative to the attachment plate 540, i.e. the distance between the first clamping plate 530 and the second clamping plate 550 is adjustable, so that the clamping assembly can be suitable for photographing devices of various specifications.

When the stabilizer 10 is in the folded state, the directions of the first clamping plate 530 to the second clamping plate 550 are parallel to the first direction. In other embodiments, the direction of the first clamping plate 530 to the second clamping plate 550 may also form an angle with the first direction, i.e. the direction of the first clamping plate 530 to the second clamping plate 550 is deviated from the first direction.

Specifically, a groove 542 is formed at one end of the connection plate 540 near the first clamping plate 530, the groove 542 extends along the direction from the first clamping plate 530 to the second clamping plate 550, and a limiting hole 544 is formed on the bottom wall of the groove 542.

The clamping assembly 500 further includes a limiting post 560, a pull rod 570 and an elastic member 580, wherein the limiting post 560 is accommodated in the groove 542, and the diameter of the limiting post 560 is larger than the diameter of the limiting hole 544, so that the limiting post 560 cannot pass through the groove 542. The pull rod 570 extends in the direction from the first clamping plate 530 to the second clamping plate 550, one end of the pull rod 570 passes through the limiting hole 544 to be connected to the limiting post 560, and the other end is connected to the second clamping plate 550. The elastic member 580 is a spring, and is sleeved on the pull rod 570, and has one end close to the limiting post 560 and the other end connected to the end of the connecting plate 540 close to the second clamping plate 550. In other embodiments, the resilient member 580 may also be directly coupled to the post 560.

When the second clamping plate 550 is pulled out, the limiting post 560 moves toward the limiting hole 544 in the groove 542, and then abuts against the elastic member 580, and the pull rod 570 protrudes out of the connecting plate 540. Continuing to pull the second clamping plate 550, the elastic member 580 is compressed under the compression of the stopper 560. After the photographing apparatus is placed between the first clamping plate 530 and the second clamping plate 550, the second clamping plate 550 is released, and the restoring force of the elastic member 580 can apply a pulling force toward the first clamping plate 530 to the second clamping plate 550, thereby tightly clamping the photographing apparatus between the first clamping plate 530 and the second clamping plate 550.

To further secure the mounting apparatus, the clamping assembly 500 of the present embodiment further includes a catch 590.

The catch 590 can limit the photographing apparatus in a direction from the open end 510 to the closed end 520 to prevent the photographing apparatus from falling from the open end 510.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
