Referring to fig. 1 to 3, a pan/tilt head 10 according to an embodiment of the present invention includes a motor 11, a rotating housing 12, and a motor base 13. The motor 11 is used for driving the load device 20 to rotate around an axis within a certain range, and the motor 11 comprises a stator 112 and a rotor 114. The rotor 114 of the motor 11 is at least partially accommodated in the rotating case 12, and the stator 112 of the motor 11 is at least partially accommodated in the motor mount 13. The motor mount 13 includes a first annular wall 1312 surrounding the stator 112 of the motor 11, the rotary case 12 includes a second annular wall 1222 surrounding the rotor 114 of the motor 11, the first annular wall 1312 and the second annular wall 1222 are at least partially overlapped to form a covering portion 132 having an annular shape disposed along a circumferential direction of the axis, and the covering portion 132 covers a space between the stator 112 and the rotor 114 of the motor 11.

The cloud platform 10 of the embodiment of the invention can drive the load device 20 to rotate through the motor 11, the covering part 132 formed by the two annular walls can change the interval path between the stator 112 and the rotor 114 which enter the motor 11 from the outside of the cloud platform 10, gravel or small stones are not easy to enter the interval between the stator 112 and the rotor 114 of the motor 11, and meanwhile, the interval between the stator 112 and the rotor 114 of the motor 11 can be made smaller, so that the reliability of the motor 11 and the cloud platform 10 is improved.

It should be noted that the pan/tilt head 10 may be a two-axis pan/tilt head or a three-axis pan/tilt head. In this manner, the pan/tilt head 10 can provide stability augmentation for the load device 20 connected to the pan/tilt head 10, so that the load device 20 can operate at a preferred attitude. In the illustrated embodiment, the head 10 is a two-axis head, in particular a two-axis quadrature head. Wherein the load device 20 may be one of a sensor, an imaging apparatus, and a mobile terminal.

The sensor may be an attitude sensor (e.g., an acceleration sensor, an angle sensor, an inertial measurement unit, etc.). The imaging device can be imaging devices such as a camera and a video camera, and the mobile terminal can be a mobile phone, a tablet personal computer, intelligent wearable equipment and the like. It is understood that the imaging apparatus may also be some mobile terminals, for example, the imaging apparatus is a mobile phone, a tablet computer, a smart wearable device, etc. with a function of taking pictures and recording videos, or the mobile terminal may also be some imaging apparatuses, which is not limited herein.

Referring to fig. 4 to 9, in particular, the covering portion 132 may be formed by partially overlapping a first annular wall 1312 and a second annular wall 1222 with different diameters in a cylindrical shape, or by overlapping and matching two annular wall portions with complementary stepped shapes at one end, or by matching one annular wall with one stepped shape at one end and another annular wall in a cylindrical shape.

Specifically, when the covering portion 132 is formed by partially overlapping the first annular wall 1312 and the second annular wall 1222 having different diameters in a cylindrical shape, the diameter of the first annular wall 1312 may be larger than that of the second annular wall 1222, and the second annular wall 1222 may at least partially protrude into the first annular wall 1312 to form the covering portion 132 (see fig. 4), whereas, the diameter of the second annular wall 1222 may be larger than that of the first annular wall 1312, and the first annular wall 1312 may at least partially protrude into the second annular wall 1222 to form the covering portion 132 (see fig. 5).

When the covering portion 132 is formed by partially overlapping and fitting the first annular wall 1312 and the second annular wall 1222 with one end having a complementary annular step shape, the step (notch portion) at one end of the first annular wall 1312 may be on the outer side while the step at one end of the second annular wall 1222 may be on the inner side so as to be complementary to fit to form the covering portion 132 (see fig. 6); it is also possible that the step at one end of the first annular wall 1312 is on the inside and the step at one end of the second annular wall 1222 is on the outside so that they can be complementarily fitted to form the covering portion 132 (see fig. 7), which is not particularly limited herein.

When the covering portion 132 is formed by fitting one annular wall having one stepped end and another annular wall having a cylindrical shape, it may be that one end of the first annular wall 1312 is stepped and the second annular wall 1222 is cylindrical, and one end of the second annular wall 1222 is fitted with the step of the first annular wall 1312 to form the covering portion 132 (see fig. 8); it is also possible that the first annular wall 1312 has a cylindrical shape and one end of the second annular wall 1222 has an annular step shape, and the one end of the first annular wall 1312 cooperates with the step of the second annular wall 1222 to form the covering portion 132 (see fig. 9). Further, the step may be located inside or outside the annular wall, and is not particularly limited herein.

The rotor 114 of the motor 11 is at least partially accommodated in the rotating casing 12, and the rotor 114 of the motor 11 may be partially accommodated in the rotating casing 12, or the rotor 114 of the motor 11 may be completely accommodated in the rotating casing 12. The stator 112 of the motor 11 is at least partially housed within the motor mount 13, as similarly understood.

Referring to fig. 1 to 3 again, in some embodiments, the motor 11 includes a first motor 116, the motor base 13 includes a first motor base 131, the rotating casing 12 includes a first casing 122, the stator 112 of the first motor 116 is at least partially accommodated in the first motor base 131, and the rotor 114 of the first motor 116 is fixedly connected to the first casing 122.

As such, the first housing 122 rotates with the rotor 114 of the first motor 116 to rotate the rotating housing 12, so that the motor 11 can drive the rotating housing 12 to rotate. Specifically, in one embodiment, as the first motor 116 drives the rotating housing 12, the rotating housing 12 rotates about the axis X of the first motor 116. The covering portion 132 formed by the first casing 122 and the first motor base 131 is circumferentially arranged along the axis X. The axis X of the first motor 116 is a driving shaft of the first motor 116.

Wherein, the first motor 116 may be a pitch axis motor 11 of the pan/tilt head 10, and the pan/tilt head 10 drives the load device 20 to rotate in the pitch direction through the first motor 116 so as to provide stability augmentation for the pan/tilt head 10 in the pitch direction.

Further, in some embodiments, the head 10 includes a load housing 14, and the first shell 122 is disposed in the load housing 14. That is, the load housing 14 can be rotated by the first motor 116 driving the rotating housing 12. Of course, the rotor 114 of the first electric machine 116 can also be fastened directly to the load housing 14.

In this way, the first shell 122 is connected to the load housing 14, and the first motor 116 can drive the first shell 122 to rotate, so as to drive the load device 20 to rotate, so that the load device 20 can work in a preferred posture. The first motor 116 may also directly drive the load housing 14 to rotate, and the first shell 122 disposed on the load housing 14 may also rotate in unison.

In one example, the pitch axis motor of pan/tilt head 10 may be directly coupled to load housing 14 to drive load device 20 in a pitch direction.

In some embodiments, the end of first annular wall 1312 of first motor mount 131 is formed with an annular first stepped structure 1314, the end of second annular wall 1222 of first casing 122 is formed with an annular second stepped structure 1224, and first stepped structure 1314 and second stepped structure 1224 complimentarily fit to form cover 132.

In this way, the covering portion 132 formed by the two annular walls can change the spacing path between the stator 112 and the rotor 114 of the first motor 116 from the outside of the head 10, and become tortuous, so that gravel or small stones are not easy to enter the spacing between the stator 112 and the rotor 114 of the first motor 116, and meanwhile, the spacing between the stator 112 and the rotor 114 of the first motor 116 can be made smaller, thereby improving the reliability of the first motor 116 and the head 10. In the illustrated embodiment, the step of the first annular wall 1312 of the first motor mount 131 is on the inside and the step of the second annular wall 1222 of the first casing 122 is on the outside.

In some embodiments, the platform 10 includes a motor cover 134 mounted on the first motor base 131, and the motor cover 134 and the first shell 122 are respectively disposed on two opposite sides of the first motor base 131.

Thus, the first motor base 131 can provide support and sealing for the first motor 116, and the motor cover 134 can facilitate the detachment and installation of the first motor 116. Meanwhile, the first motor 116 may be disposed in a relatively sealed space formed by the cooperation of the first casing 122, the motor base 13 and the motor cover 134, which is beneficial to protecting the first motor 116 from being easily interfered by the external environment, thereby improving the reliability of the first motor 116.

In some embodiments, the motor 11 includes a second motor 118, the motor base 13 includes a second motor base 133, the head 10 includes a first shaft arm 15, the rotating shell 12 includes a second shell 124, the first shaft arm 15 connects the second shell 124 and the first motor base 131, the stator 112 of the second motor 118 is at least partially accommodated in the second motor base 133, and the rotor 114 of the second motor 118 is fixedly connected to the second shell 124.

It is understood that the second motor 118 may be a yaw axis motor of the pan/tilt head 10, the second casing 124 may rotate with the rotor 114 of the second motor 118, and the second motor 118 drives the second casing 124 to rotate the first axis arm 15 and the first motor base 131, and further drives the load device 20 to rotate around the axis Y of the second motor 118. Wherein the axis Y of the second motor 118 is a driving shaft of the second motor 118. As such, the second motor 118 may provide stability to the load device 20 in a different direction of rotation than the first motor 116, and the second motor mount 133 may provide support for the second motor 118. Specifically, the first shaft arm 15 and the second housing 124 are fixedly connected (e.g., may be made as an integral structure), and the first shaft arm 15 and the first motor base 131 are detachably connected (e.g., fixed by screws).

Specifically, when the second motor 118 drives the load device 20 to rotate, the load device 20 rotates around the axis Y of the second motor 118. In one example, the head 10 may be an orthogonal head, with the axis Y of the second motor 118 being perpendicular to the axis X of the first motor 116. Of course, in other examples, the head 10 may be a non-orthogonal head, and the axis Y of the second motor 118 is not perpendicular and parallel to the axis X of the first motor 116.

In some embodiments, the head 10 includes a first cover 135 mounted on an outer side of the second housing 124 and a second cover 136 mounted on an outer side of the second motor mount 133, the outer side of the second housing 124 and the outer side of the second motor mount 133 facing away from each other.

So, first lid 135 and second lid 136 are favorable to the dismouting and the sealed of second motor 118 and second motor cabinet 133, and simultaneously, second motor 118 can set up in the relatively inclosed space that first lid 135, second shell 124, second motor cabinet 133 and second lid 136 cooperation formed, is favorable to protecting second motor 118 and is difficult to receive external environment's interference to improve second motor 118's reliability.

In some embodiments, the end of the first annular wall 1312 of the second motor mount 133 is formed with an annular third step structure 1242 (see fig. 3), and the third step structure 1242 at least partially extends into the space surrounded by the second annular wall 1222 of the second case 124 to form the covering portion 132.

In this embodiment, the second annular wall 1222 of the second casing 124 is cylindrical, and the second annular wall 1222 of the second casing 124 and the third step structure 1242 cooperate to form the covering portion 132, so that the covering portion 132 formed by the two annular walls can change the distance between the stator 112 and the rotor 114 entering the second motor 118 from the outside of the tripod head 10, and gravel or small stones cannot easily enter the distance between the stator 112 and the rotor 114 of the second motor 118, and at the same time, the distance between the stator 112 and the rotor 114 of the second motor 118 can be made smaller, thereby improving the reliability of the second motor 118 and the tripod head 10. In the illustrated embodiment, the step of the first annular wall 1312 of the second motor mount 133 is disposed outside.

In some embodiments, first axis arm 15 has a channel 151 formed therein, and head 10 includes a line connection 152, where line connection 152 is located within channel 151 and connects stator 112 of first motor 116 and rotor 114 of second motor 118.

Thus, the first motor 116 and the second motor 118 can control and supply power to the first motor 116, the circuit connecting portion 152 is disposed in the first shaft arm 15 to prevent the circuit from being exposed outside the cradle head 10, and the circuit connecting portion 152 is not easily interfered by external rings to ensure reliability.

In some embodiments, the first axle arm 15 includes a first arm body 153 and a first side cover 154, the first axle arm 15 is formed with a first groove 155, and the first side cover 154 covers the first groove 155 to form the channel 151. In this manner, the head 10 can inspect and disassemble the line connection portion 152 in the channel 151 by disassembling the first side cover 154. The first arm 153 and the first side cover 154 may be detachably connected. In one example, the first arm 153 and the first side cover 154 are detachably connected by a snap structure.

In some embodiments, the head 10 includes a second arm 16, the first arm 15 and the second arm 16 are symmetrically coupled to a second housing 124 along an axis Y of the second motor 118, the head 10 includes a load housing 14, the first housing 122 is disposed on the load housing 14, and the second arm 16 is rotatably coupled to the load housing 14.

Thus, the first shaft arm 15 and the second shaft arm 16 are connected with the load shell 14, so that the load of a single shaft arm can be reduced, meanwhile, the balance of the holder 10 can be kept, the structural stability of the holder 10 is improved, and the stability-enhancing performance of the load equipment 20 can also be improved.

In some embodiments, the platform 10 includes a support shaft 17, the first shell 122 and the support shaft 17 are disposed on opposite sides of the load housing 14, and the second arm 16 is rotatably connected to the support shaft 17.

In this way, the second shaft arms 16 are symmetrically arranged with respect to the first shaft arms 15 on both sides of the load device 20, and the structural stability of the pan/tilt head 10 can be maintained. The support shaft 17 ensures that the load housing 14 can be smoothly rotated by the support of the first shaft arm 15.

In some embodiments, the head 10 includes a third annular wall 142 and a connecting seat 18 rotatably connected, the third annular wall 142 is disposed on the load housing 14 and surrounds the support rotation shaft 17, the second shaft arm 16 connects the second housing 124 and the connecting seat 18, the connecting seat 18 includes a fourth annular wall 182 surrounding the support rotation shaft 17, an end surface of the fourth annular wall 182 is formed with an annular groove 1822, and the third annular wall 142 is at least partially received in the annular groove 1822.

Thus, the third annular wall 142 and the fourth annular wall 182 cooperate to change the path from the outside of the cradle head 10 to the inside of the connecting seat 18, and gravel or small stones are not easy to enter the connecting seat 18 to affect the rotation of the supporting rotating shaft 17, thereby improving the reliability of the supporting rotating shaft 17 and the cradle head 10.

In addition, the load housing 14 is further provided with a first limiting portion 144, the annular groove 1822 is provided with a second limiting portion (not shown), and the first limiting portion 144 and the second limiting portion have an interference position on the circumference of the load housing 14, so that when the load housing 14 rotates to an angle at which the first limiting portion 144 interferes with the second limiting portion, the load housing 14 stops rotating due to interference of the first limiting portion 144 and the second limiting portion, and further, the damage of components caused by excessive rotation of the cradle head 10 can be avoided. In the illustrated embodiment, the first stopper 144 is located in the space surrounded by the third annular wall 142 and connects the inner wall of the third annular wall 142 and the support shaft 17.

In some embodiments, head 10 includes a weight 19, and weight 19 is mounted within connecting base 18.

It can be understood that connecting seat 18 and the cooperation of supporting pivot 17 make load device 20 can steadily rotate to can not set up the motor in connecting seat 18, so, balancing weight 19 can replace the motor, makes the focus of cloud platform 10 balanced, is favorable to further keeping cloud platform 10 stable, improves user experience.

In some embodiments, the head 10 includes a control circuit 162, the second shaft arm 16 is formed with a receiving space 161, and the control circuit 162 is disposed in the receiving space 161 and mounted on the rotor 114 of the second motor 118.

It can be understood that the rotor 114 of the second motor 118 is fixedly connected to the second housing 124, and the second shaft arm 16 is fixedly connected to the second housing 124, such that the control circuit 162 is installed on the rotor 114 of the second motor 118, the control circuit 162 can rotate with the rotor 114 of the second motor 118, and the control circuit 162 is disposed in the second shaft arm 16, which can maintain the connection stability between the control circuit 162 and the second motor 118, and the control circuit 162 is not easily affected by the external environment to ensure the reliability, and at the same time, the space and weight configuration of the pan/tilt head 10 can be optimized.

Specifically, the second arm 16 includes a second arm body 163 and a second side cover 164, the second arm 16 is formed with a second groove 165, and the second side cover 164 covers the second groove 165 to form an accommodating space 161.
