The following describes the pan/tilt/pivot arm assembly, the pan/tilt apparatus, and the photographing apparatus in detail with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.

Referring to fig. 1 to 4, an embodiment of the present application provides a pan/tilt/pivot arm assembly 100, which includes a first connecting arm 10, a second connecting arm 20 rotatably connected to the first connecting arm 10, and a limiting assembly. The pan/tilt/pivot arm assembly 100 can carry a camera, and when the pan/tilt/pivot arm assembly 100 works, the second connecting arm 20 can rotate relative to the first connecting arm 10 to adjust the shooting angle of the camera. Alternatively, the second connecting arm 20 may be a shaft arm, and the first connecting arm 10 may be a power assembly for driving the shaft arm to rotate, and the camera is mounted on the shaft arm.

The limiting assembly comprises a first limiting member 31 and a second limiting member 32, the first limiting member 31 is disposed on one of the first connecting arm 10 and the second connecting arm 20, and the second limiting member 32 is disposed on the other of the first connecting arm 10 and the second connecting arm 20. The first limiting member 31 and the second limiting member 32 are located on the same circumferential track, and at least partially overlap each other along the rotational axis of the second connecting arm 20. It can be understood that the first limiting member 31 and the second limiting member 32 are located on the same circumferential track, which can ensure that the first limiting member 31 and the second limiting member 32 can contact each other during the rotation process of the second connecting arm 20 relative to the first connecting arm 10. In the example shown in the drawings, the rotation axis of the second connecting arm 20 is along the vertical direction, and the first limiting member 31 and the second limiting member 32 at least partially overlap along the rotation axis of the second connecting arm 20, which can be understood that the first limiting member 31 and the second limiting member 32 at least partially overlap along the vertical direction, so that the second limiting member 32 can contact the first limiting member 31 during the rotation of the second connecting arm 20 relative to the first connecting arm 10. In the embodiment, the first limiting member 31 is a boss structure and is disposed on the first connecting arm 10, and the second limiting member 32 is a boss structure and is disposed on the second connecting arm 20.

The pan/tilt/pivot arm assembly 100 includes a locked state and a free state. When the pan/tilt/pivot arm assembly 100 is in the locked state, the second connecting arm 20 rotates to the first position relative to the first connecting arm 10, as shown in fig. 1 and 3, the first limiting member 31 abuts against the second limiting member 32, so that the second connecting arm 20 is in the locked state relative to the first connecting arm 10. It can be understood that the cradle head shaft arm assembly 100 does not need to be used or is not easy to damage when being used in a storage state, and the cradle head shaft arm assembly 100 cannot rotate randomly by mutually locking the first connecting arm 10 and the second connecting arm 20.

When the pan/tilt/pivot arm assembly 100 is in the free state, the second connecting arm 20 rotates to the second position relative to the first connecting arm 10, and drives the second limiting member 32 to move in the direction away from the first limiting member 31, so that the first limiting member 31 and the second limiting member 32 are separated from each other, as shown in fig. 2 and 4, the second connecting arm 20 is in the free state relative to the first connecting arm 10, and the pan/tilt/pivot arm assembly 100 can be normally used.

Through the arrangement, when the holder shaft arm assembly 100 is not required to be used, the second connecting arm 20 is rotated to the first position, and the first limiting part 31 and the second limiting part 32 are matched to lock the first connecting arm 10 and the second connecting arm 20 mutually, so that the product is stable in shape, cannot rotate randomly and is not easy to damage. When the holder arm assembly 100 needs to be used, the second connecting arm 20 is rotated to the second position, so that the first connecting arm 10 and the second connecting arm 20 are separated from each other, and the holder arm assembly 100 is in a free state, so that the holder arm assembly 100 can be normally used.

In some alternative embodiments, the first limiting member 31 and the second limiting member 32 may be locked or unlocked by a mechanical structure, may be locked or unlocked by a magnetic attraction, or may be locked or unlocked by a combination of a mechanical structure and a magnetic attraction.

As shown in fig. 1 to 4, in some alternative embodiments, the first limiting member 31 and the second limiting member 32 are locked or unlocked with each other in a magnetic attraction manner. One of an end (shown as a right end surface in the figure) of the second limiting member 32, which is used for abutting against the first limiting member 31, and an end (shown as a left end surface in the figure) of the first limiting member 31, which is used for abutting against the second limiting member 32, is provided with a third magnet, and the other of an end of the second limiting member 32, which is used for abutting against the first limiting member 31, and an end of the first limiting member 31, which is used for abutting against the second limiting member 32, is provided with a magnet material. Alternatively, the third magnet may be a magnet, and the magnetic material member may be a material capable of being attracted by the magnet, such as iron, copper, or the like. In other embodiments, the piece of magnet material may be replaced with a fourth magnet that is magnetically opposite the third magnet, enhancing the magnetic attraction with the third magnet.

When the pan/tilt/pivot arm assembly 100 is not needed to be used, the second connecting arm 20 can rotate to the first position relative to the first connecting arm 10, as shown in fig. 1 and 3, the third magnet and the magnetic material are attracted to each other, and the first limiting member 31 and the second limiting member 32 are abutted to each other by the magnetic attraction between the third magnet and the magnetic material, so that the second connecting arm 20 is in a locked state relative to the first connecting arm 10, and the pan/tilt/pivot arm assembly 100 is in a locked state.

When the pan/tilt/pivot arm assembly 100 needs to be used, the second connecting arm 20 can overcome the magnetic attraction between the third magnet and the magnetic material, and rotate to the second position relative to the first connecting arm 10, so as to drive the second limiting member 32 to move in the direction away from the first limiting member 31, as shown in fig. 2 and 4, so that the first limiting member 31 and the second limiting member 32 are separated from each other, and thus the second connecting arm 20 is in a free state relative to the first connecting arm 10, and the pan/tilt/pivot arm assembly 100 is in a free state, so that the pan/tilt/pivot arm assembly 100 can be normally used.

Referring to fig. 5 to 9, in some alternative embodiments, the first limiting member 31 and the second limiting member 32 are locked or unlocked with each other in a mechanical structure manner. The limiting assembly may further include a third limiting member 33, wherein the third limiting member 33 and the first limiting member 31 are disposed on the same one of the first connecting arm 10 and the second connecting arm 20, and are located on the same circumferential track as the first limiting member 31. In the present embodiment, the first limiting member 31 and the third limiting member 33 are disposed on the first connecting arm 10, and the second limiting member 32 is disposed on the second connecting arm 20. The first limiting part 31, the second limiting part 32 and the third limiting part 33 are located on the same circumferential track, so that the second limiting part 32, the first limiting part 31 and the third limiting part 33 can contact with each other in the process that the second connecting arm 20 rotates relative to the first connecting arm 10.

When the pan/tilt/pivot arm assembly 100 is not needed to be used, the second connecting arm 20 can rotate to a first position relative to the first connecting arm 10, the second limiting member 32 is located between the first limiting member 31 and the third limiting member 33, and two ends of the second limiting member 32 are respectively abutted against the first limiting member 31 and the third limiting member 33, as shown in fig. 5 and 7, the third limiting member 33 provides an acting force to the second limiting member 32 in a direction toward the first limiting member 31, so that the first limiting member 31 and the second limiting member 32 are abutted against each other, and thus the second connecting arm 20 is in a locked state relative to the first connecting arm 10, and the pan/tilt/pivot arm assembly 100 is in a locked state.

When the cradle head shaft-arm assembly 100 needs to be used, the second connecting arm 20 can overcome the action force between the third limiting part 33 and the second limiting part 32, and the action force is opposite to that of the first connecting arm 10, so as to drive the second limiting part 32 to move in the direction away from the first limiting part 31, so that the first limiting part 31 and the second limiting part 32 are separated from each other, and the second connecting arm 20 rotates to the second position, as shown in fig. 6 and 9, so that the second connecting arm 20 is in a free state relative to the first connecting arm 10, and the cradle head shaft-arm assembly 100 is in a free state, so that the cradle head shaft-arm assembly 100 can be normally used.

In some alternative embodiments, the third limiting member 33 includes a main body portion 34 and an elastic portion 35, and the main body portion 34 and the first limiting member 31 are disposed on the same one of the first connecting arm 10 and the second connecting arm 20, and are located on the same circumferential track as the first limiting member 31. The elastic portion 35 is connected to a side of the main body portion 34 close to the first limiting member 31, and the elastic portion 35 and the second limiting member 32 at least partially overlap in the rotation axial direction of the second connecting arm 20. In the present embodiment, the first limiting member 31 and the main body 34 are disposed on the first connecting arm 10, and the second limiting member 32 is disposed on the second connecting arm 20. Alternatively, the body portion 34 may be connected to the first connecting arm 10 by screwing, welding, bonding, interference fit, or the like. The elastic portion 35 may be connected to the main body portion 34 by welding, bonding, interference fit, or the like. The elastic portion 35 may be made of a flexible material such as plastic or rubber. The elastic portion 35 may include at least one of an elastic sheet, a plastic member and a rubber member.

In the examples shown in fig. 7 to 9, the rotation axis of the second connecting arm 20 is along the vertical direction, and the elastic portion 35 and the second limiting member 32 at least partially overlap along the rotation axis of the second connecting arm 20, which can be understood as that the elastic portion 35 and the second limiting member 32 at least partially overlap along the vertical direction, so that the second limiting member 32 can contact the elastic portion 35 and deform the elastic portion 35 during the rotation of the second connecting arm 20 relative to the first connecting arm 10.

When the pan/tilt/pivot arm assembly 100 is not used, the second connecting arm 20 can rotate to a first position relative to the first connecting arm 10, a first end of the second limiting member 32 abuts against the first limiting member 31, a second end of the second limiting member 32 abuts against the elastic portion 35, as shown in fig. 5 and 7, the elastic portion 35 provides an acting force towards the first limiting member 31 to the second limiting member 32, so that the first limiting member 31 abuts against the second limiting member 32, the elastic portion 35 performs a limiting function on the second limiting member 32, and the second limiting member 32 is prevented from being disengaged from the first limiting member 31, so that the second connecting arm 20 is in a locking state relative to the first connecting arm 10, and the pan/tilt/pivot arm assembly 100 is in a locking state.

When the holder shaft-arm assembly 100 needs to be used, the second connecting arm 20 can overcome the action force between the elastic portion 35 and the second limiting member 32, and rotate relative to the first connecting arm 10, so as to drive the second limiting member 32 to move in the direction away from the first limiting member 31, and thus the first limiting member 31 and the second limiting member 32 are separated from each other. During the rotation of the second connecting arm 20 from the first position to the second position, the elastic portion 35 is pressed by the second limiting member 32 and deformed upward, as shown in fig. 8. After the second connecting arm 20 rotates to the second position, as shown in fig. 6 and 9, the second limiting member 32 is located on one side of the elastic portion 35 away from the first limiting member 31, the elastic portion 35 returns to the reset state, and no acting force exists between the elastic portion 35 and the second limiting member 32, so that the second connecting arm 20 is in a free state relative to the first connecting arm 10, and the pan/tilt/pivot arm assembly 100 is in a free state, so that the pan/tilt/pivot arm assembly 100 can be normally used.

In an embodiment, when the second connecting arm 20 is located at the first position, the elastic portion 35 is in a deformed state and abuts against the second limiting member 32, and the elastic portion 35 provides the acting force to the second limiting member 32 through an elastic force generated by the deformation, so as to press the second limiting member 32 against the first limiting member 31, thereby locking the two members with each other.

Alternatively, the third magnet may be a magnet, and the magnetic material member may be a material capable of being attracted by the magnet, such as iron, copper, or the like. In other embodiments, the piece of magnet material may be replaced with a fourth magnet that is magnetically opposite the third magnet, enhancing the magnetic attraction with the third magnet.

When the second connecting arm 20 is located at the first position, the elastic portion 35 is in a deformed state and abuts against the second limiting member 32, and the third magnet and the magnetic material are attracted to each other. The elastic portion 35 provides the acting force to the second limiting member 32 through the elastic force generated by deformation and the magnetic attraction between the third magnet and the magnetic material, so as to strengthen the acting force of the third limiting member 33 to the second limiting member 32, so that the second limiting member 32 compresses the first limiting member 31, and thus the first limiting member 31 and the second limiting member 32 are locked with each other.

In another embodiment, a first magnet is disposed at one end (shown as a right end surface) of the elastic portion 35 close to the first limiting member 31, and a second magnet is disposed at one end (shown as a left end surface) of the second limiting member 32, which is used for abutting against the elastic portion 35, and the second magnet has the same magnetism as the first magnet.

The elastic portion 35 provides the acting force to the second limiting member 32 by the repulsive force between the second magnet and the first magnet, and presses the second limiting member 32 against the first limiting member 31, thereby locking the two members to each other.

Further, in order to achieve a better locking effect, one of an end of the second limiting member 32 abutting against the first limiting member 31 and an end of the first limiting member 31 abutting against the second limiting member 32 is provided with a third magnet, and the other of an end of the second limiting member 32 abutting against the first limiting member 31 and an end of the first limiting member 31 abutting against the second limiting member 32 is provided with a magnetic material. Alternatively, the third magnet may be a magnet, and the magnetic material member may be a material capable of being attracted by the magnet, such as iron, copper, or the like. In other embodiments, the piece of magnet material may be replaced with a fourth magnet that is magnetically opposite the third magnet, enhancing the magnetic attraction with the third magnet.

When the second connecting arm 20 is at the first position, the elastic portion 35 is in a reset state and abuts against the second limiting member 32, the second magnet and the first magnet repel each other, and the third magnet and the magnetic material attract each other. The elastic portion 35 provides the acting force to the second limiting member 32 through the repulsive force between the second magnet and the first magnet and the magnetic attractive force between the third magnet and the magnetic material, so as to strengthen the acting force of the third limiting member 33 to the second limiting member 32, so that the second limiting member 32 presses the first limiting member 31, and thus the first limiting member 31 and the second limiting member 32 are locked to each other.

In another embodiment, a first magnet is disposed at one end (shown as a right end surface) of the elastic portion 35 close to the first limiting member 31, and a second magnet is disposed at one end (shown as a left end surface) of the second limiting member 32, which is used for abutting against the elastic portion 35, and the second magnet has the same magnetism as the first magnet. Alternatively, the second magnet and the first magnet may adopt magnets with opposite magnetism.

When the second connecting arm 20 is located at the first position, the elastic portion is in a deformed state and abuts against the second limiting member 32, and the second magnet and the first magnet repel each other. The elastic portion 35 provides the acting force to the second limiting member 32 through the elastic force generated by the deformation and the repulsive force between the second magnet and the first magnet, and presses the second limiting member 32 against the first limiting member 31, so as to lock the two members to each other.

Further, in order to achieve a better locking effect, one of an end of the second limiting member 32 abutting against the first limiting member 31 and an end of the first limiting member 31 abutting against the second limiting member 32 is provided with a third magnet, and the other of an end of the second limiting member 32 abutting against the first limiting member 31 and an end of the first limiting member 31 abutting against the second limiting member 32 is provided with a magnetic material. Alternatively, the third magnet may be a magnet, and the magnetic material member may be a material capable of being attracted by the magnet, such as iron, copper, or the like. In other embodiments, the piece of magnet material may be replaced with a fourth magnet that is magnetically opposite the third magnet, enhancing the magnetic attraction with the third magnet.

When the second connecting arm 20 is located at the first position, the elastic portion 35 is in a deformed state and abuts against the second limiting member 32, the second magnet and the first magnet repel each other, and the third magnet and the magnetic material member attract each other. The elastic portion 35 provides the acting force to the second limiting member 32 through the elastic force generated by deformation, the repulsive force between the second magnet and the first magnet, and the magnetic attractive force between the third magnet and the magnetic material member, so as to strengthen the acting force of the third limiting member 33 to the second limiting member 32, so that the second limiting member 32 compresses the first limiting member 31, and thus the first limiting member 31 and the second limiting member 32 are locked to each other.

In some alternative embodiments, the elastic part 35 includes a first elastic member 351 connected to the body part 34 and a second elastic member 352 connected to the first elastic member 351 in a bent manner. Alternatively, both the first elastic member 351 and the second elastic member 352 may be integrally formed. When the second connecting arm 20 is at the first position, the second end of the second limiting member 32 abuts against the second elastic member 352, as shown in fig. 5 and 7. When the second connecting arm 20 is at the second position, the second limiting member 32 is located on a side of the second elastic member 352 away from the first limiting member 31, as shown in fig. 6 and 9.
