Referring to fig. 1 and 2, in some embodiments, axle assembly 200 includes a pitch axle assembly 203, a roll shaft assembly 204, and a yaw axle assembly 205. The pitch shaft assembly 203 includes a pitch shaft arm 2031 and a pitch shaft motor 2032, the roll shaft assembly 204 includes a roll shaft arm 2041 and a roll shaft motor 2042, and the yaw shaft assembly 205 includes a yaw shaft arm 2051 and a yaw shaft motor 2052. One end of the tilt shaft arm 2031 is connected to the rotor of the tilt shaft motor 2032, and the other end is connected to the imaging apparatus 2000. One end of the tilting shaft arm 2041 is connected to the rotor of the tilting shaft motor 2042, and the other end is connected to the stator of the pitch shaft motor 2032. One end of the yaw axis shaft arm 2051 is connected to a rotor of the yaw axis motor 2052, the other end is connected to a stator of the turning axis shaft motor 2042, and the stator of the yaw axis shaft motor 2052 is used for connecting external elements. Wherein the weight assembly 100 is detachably clamped to at least one of the pitch axis motor 2032, the roll axis motor 2042, and the yaw axis motor 2052 by the clamping structure 10.

So, can install counter weight component 100 on pitch axis motor 2032, roll axis motor 2042 and yaw axis motor 2052 at least to make counter weight component 100 can adjust the focus of cloud platform 1000, thereby can carry out balanced regulation to cloud platform 1000 and shooting device 2000, so that cloud platform 1000 can carry out stable increase steady and the gesture is adjusted to shooting device 2000, in order to obtain better shooting effect.

Referring to fig. 1, in an example, the camera 2000 is mounted on the pan/tilt head 1000, the camera 2000 is a camera, and the tilting roller motor 2042 rotates to sink the side of the pan/tilt head 1000 on which the camera 2000 is mounted due to the heavy weight of the camera, so that the pan/tilt head 1000 and the camera 2000 need to be balanced and adjusted by the counterweight assembly 100. In fig. 2, the weight assembly 100 is clamped on the pitch axis motor 2032 to perform balance adjustment on the roll axis motor 2042, so that the cradle head 1000 and the photographing device 2000 are in a balance position, and stable stability augmentation and posture adjustment can be provided for the photographing device 2000 after the cradle head 1000 is powered on and started. It can be seen that the distance from the counterweight assembly 100 disposed on the tilting shaft arm 2041 to the tilting shaft motor 2042 is smaller than the distance from the counterweight assembly 100 disposed on the tilting shaft motor 2032 to the tilting shaft, so that the moment arm of the counterweight assembly 100 disposed on the tilting shaft motor 2032 is larger for the counterweight assembly 100 of the same weight, and a larger adjusting force can be provided to perform balance adjustment on the photographing device 2000 and the pan/tilt head 1000. That is, in the case where the same amount of adjustment force is required, the weight assembly 100 provided at the pitch axis motor 2032 may have a smaller weight than the weight assembly 100 provided at the roll axis arm 2041. Therefore, the arrangement of the counterweight assembly 100 at the motor 202 of the cradle head 1000 is beneficial to improving the effect of adjusting the balance of the counterweight assembly 100, i.e. reducing the weight of the counterweight assembly 100, so as to reduce the overall weight of the cradle head 1000, and especially when the cradle head 1000 is a handheld cradle head, the weight of the cradle head 1000 is reduced to improve the user experience. Therefore, in the present embodiment, the weight assembly 100 is preferably mounted on the motor 202 of the platform 1000.

In addition, it should be noted that the pan/tilt head 1000 according to the embodiment of the present invention may be an orthogonal pan/tilt head or a non-orthogonal pan/tilt head, and is not limited herein. Specifically, when the pan/tilt head 1000 is an orthogonal cloud platform, the rotation axes of the pitch axis arm 2031, the roll axis arm 2041, and the yaw axis arm 2051 are orthogonal in pairs, and when the pan/tilt head 1000 is an orthogonal cloud platform, the rotation axes of the pitch axis arm 2031, the roll axis arm 2041, and the yaw axis arm 2051 are non-orthogonal in pairs, or the rotation axes of two of the two of.

In the above embodiment, the pan/tilt head 1000 is a three-axis pan/tilt head, and the shaft arms of the three shaft assemblies of the pan/tilt head 1000 can rotate, so as to drive the shooting device 2000 to move freely in the space, and thus, when the pan/tilt head 1000 is balanced, the counterweight assembly 100 can be installed at least in the pitch shaft motor 2032, the roll shaft motor 2042, and the yaw shaft motor 2052 according to practical situations. It is understood that in other embodiments, the pan/tilt head 1000 may be a two-axis pan/tilt head, for example, the pan/tilt head 1000 may have at least two of the pitch axis assembly 203, the roll axis assembly 204, and the yaw axis assembly 205, or in the illustrated pan/tilt head, only two axis assemblies may move, the counterweight assembly 100 may be clamped on the motor of at least one axis assembly to adjust the center of gravity, and the specific installation manner may be determined according to actual circumstances, for example, in the illustrated embodiment, the yaw axis motor 2052 may be locked, and the pan/tilt head 1000 may drive the shooting device to move through the pitch axis motor 2032 and the roll axis motor 2042, so that the counterweight assembly 200 may be installed on the pitch axis motor 2032 and/or the roll axis motor 2042 to adjust the center of gravity.

Of course, in some embodiments, the pan/tilt head 1000 may also be a single-axis pan/tilt head, that is, the pan/tilt head 1000 only has one of the pitch axis assembly 203, the roll axis assembly 204, and the yaw axis assembly 205, or in the illustrated pan/tilt head, only one of the axis assemblies may move, for example, in the illustrated embodiment, the roll axis motor 2042 and the yaw axis motor 2052 may be locked, and the pan/tilt head 1000 may only drive the camera to move through the pitch axis motor 2032, so that the counterweight assembly 200 may be mounted on the pitch axis motor 2032 to adjust the center of gravity.

Referring to fig. 1-3, in some embodiments, a clamping structure 10 includes a body 11 and a locking mechanism 12. The weight member 20 is detachably connected to the body 11, and the locking mechanism 12 is disposed on one side of the body 11 and movably connected to the body 11. Wherein the locking mechanism 12 is capable of cooperating with the body 11 when moving towards the side of the body 11 to lock the holding structure 10 on the motor 202, and the locking mechanism 12 is further capable of moving towards the side of the body 11 to unlock the holding structure 10 from the motor 202.

In this manner, the clamping structure 10 can be mounted on the motor 202 or the clamping structure 10 can be dismounted from the motor 202 by the action of the locking mechanism 12, so as to facilitate the dismounting of the weight assembly 100.

Specifically, in the process of installing the counterweight assembly 100 to the motor 202, the clamping structure 10 can be locked on the motor 202 through the locking mechanism 12, and then the counterweight block 20 is installed on the body 11, when the counterweight assembly 100 needs to be disassembled from the motor 202, only the clamping structure 10 and the motor 202 need to be unlocked through the locking mechanism 12, and the dismounting is simple and convenient.

Further, referring to fig. 3 and 4, in some embodiments, locking mechanism 12 includes a tightening block 121 and a locking member 122. The tightening block 121 is located on one side of the body 11 and can move relative to the body 11, and the locking member 122 is located on one side of the tightening block 121 facing away from the body 11. Wherein, the locking member 122 can move towards the side where the body 11 is located to drive the tightening block 121 to move so that the tightening block 121 tightens against the motor 202, so that the tightening block 121 cooperates with the body 11 to lock the clamping structure 10 on the motor 202. The locking member 122 is also movable to release the jacking blocks 121 towards the side facing away from the body 11, so that the jacking blocks 121 can be separated from the motor 202 to unlock the clamp structure 10 from the motor 202.

In this way, the movement of the tightening block 121 can be controlled by the movement of the locking member 122, so that the tightening block 121 cooperates with the body 11 to lock the clamping structure 10 on the motor 202, or unlock the clamping structure 10 from the motor 202.

Still further, referring to fig. 4, in some embodiments, a through hole 1211 is formed on the tightening block 121, and the body 11 is formed with a first mounting hole 111. The locker 122 includes a screw portion 1221 and a knob portion 1222, the screw portion 1221 is inserted through the through hole 1211 and is screw-coupled to the first mounting hole 111, the knob portion 1222 is mounted on the screw portion 1221 and is screw-coupled to the screw portion 1221, and the knob portion 1222 is movable on the screw portion 1221. Wherein, when the knob portion 1222 moves towards the side of the body 11, the knob portion 1222 can drive the tightening block 121 to move so that the tightening block 121 tightens against the motor 202, and when the knob portion 1222 moves towards the side away from the body 11, the knob portion 1222 releases the tightening block 121 so that the tightening block 121 can be separated from the motor 202.

Thus, the tightening block 121 can be tightened against the motor 202 to cooperate with the body 11 to lock the clamping structure 10 on the motor 202 by rotating the knob portion 1222 to move the knob portion 1222 on the threaded portion 1221 toward the side of the body 11 to further drive the tightening block 121 against the motor 202 to move toward the side of the body 11, and the tightening block 121 can be released by rotating the knob portion 1222 to move the knob portion 1222 on the threaded portion 1221 toward the side away from the body 11 to release the tightening block 121 to allow the tightening block 121 to be separated from the motor 202 to unlock the clamping structure 10 from the motor 202.

Specifically, in such an embodiment, the threaded portion 1221 and the first mounting hole 111 are threaded and fixed with respect to the body 11, the knob portion 1222 is sleeved on the threaded portion 1221 and threaded with the threaded portion 1221, when it is required to lock the clamping structure 10 on the motor 202, the knob portion 1222 can be rotated to make the knob portion 1222 move on the threaded portion 1221 to one side of the body 11 along the axial direction of the first mounting hole 111, during the movement, the knob portion 1222 gradually approaches the tightening block 121 and then abuts against the tightening block 121, and further drives the tightening block 121 to move to one side of the body 11 to tighten the motor 202, so that the tightening block 121 and the body 11 cooperate to lock the clamping structure 10 on the motor 202, and in such a state, the tightening block 121 is fixed with the body 11.

When the clamping structure 10 needs to be unlocked from the motor 202, the knob portion 1222 can be rotated reversely to move the knob portion 1222 toward the side away from the body 11 at the threaded portion 1221, so that the knob portion 1222 gradually releases the tightening block 121, and in such a state, the tightening block 121 can move relative to the body 11, so that the tightening block 121 can be separated from the motor 202 by pushing the tightening block 121 toward the side away from the body 11, thereby unlocking the clamping structure 10 from the motor 202.

In addition, in some embodiments, the periphery of the knob portion 1222 may be formed with a non-slip region for increasing friction between the knob portion 1222 and the knob portion 1222 when the knob portion 1222 is rotated, which may facilitate easier rotation of the knob portion 1222 by a user.

Referring to fig. 4, in some embodiments, the thread portion 1221 may be a screw, and the knob portion 1222 may be a threaded portion that is sleeved on and threadedly connected to the threaded portion of the screw, but in other embodiments, the thread portion 1221 may also be a threaded element such as a bolt, and the like, and the threaded portion 1221 is not limited thereto, and only the knob portion 1222 can move on the thread cloth 1221 when the knob portion 1222 is rotated.

In some embodiments, a flat washer and a resilient washer may be further disposed between the knob portion 1222 and the top block 121, so that when the knob portion 1222 locks the top block 121, the resilient washer has a certain elasticity to abut against the threaded portion 1222 and the top block 121 to effectively prevent the knob portion 1222 from being loosened when being vibrated by the outside.

It is understood that in other embodiments, the threaded portion 1221 may be fixedly disposed with the knob portion 1222, that is, when the knob portion 1222 is rotated, the threaded portion 1221 follows the knob portion 1222 to move the threaded portion 1221 and the knob portion 1222 integrally along the axial direction of the first mounting hole 111. Therefore, when the threaded portion 1221 and the knob portion 1222 are rotated to move toward the side of the body 11, the knob portion 1222 gradually approaches the tightening block 121, and then abuts against the tightening block 121 to move the tightening block 121 toward the side of the body 11, so that the tightening block 121 presses against the motor 202, thereby locking the clamping structure 10 on the motor 202. When the screw portion 1221 and the knob portion 1222 are rotated to move away from the side of the body 11, the knob portion 1222 releases the tightening block 121, so that the tightening block 121 can move away from the side of the body 11 by an external force, thereby separating from the motor 202 to release the locking of the clamping structure 10 and the motor 202.

In addition, in the above embodiment, during the locking process, the knob portion 1222 moves first, and then abuts against the tightening block 121 to drive the tightening block 121 to move, so that the tightening block 121 tightens against the motor 202 to achieve the locking, and during the unlocking process, the knob portion 1222 releases the tightening block 121, so that the user can push the tightening block 121 to separate from the motor 202, thereby achieving the unlocking.
