Referring to fig. 1 and 7, a photographing head includes: the self-balancing mechanism comprises a shell 100, a mounting seat 200, a connecting seat 300, a self-balancing mechanism 700 and a conversion mechanism 400; the mounting seat 200 is disposed in the housing 100; a hollow connecting ball head 500 is arranged on the connecting seat 300, and an opening 530 is arranged at the bottom of the connecting ball head 500; self-balancing mechanism 700 is disposed on mounting base 200, and mounting base 200 passes through opening 530 and extends self-balancing mechanism 700 into connecting ball 500; conversion mechanism 400 is provided on connection holder 300, connection ball 500 has a first state in which it can perform universal rotation with respect to housing 100, connection ball 500 has a second state in which it can perform only pitch rotation with respect to housing 100, and conversion mechanism 400 can convert connection ball 500 between the first state and the second state. The docking cradle 300 may be used to couple with a photographing apparatus. The connection ball 500 sleeved outside the mounting seat 200 can perform universal movement relative to the mounting seat 200, thereby realizing adjustment of orientation angles of the connection seat 300 in multiple directions. In the process of adjusting the angle of the connection base 300, the universal motion of the connection ball 500 may be converted into the rotation only in the pitch direction using the conversion mechanism 400. By using the conversion mechanism 400, the angle adjustment process of the connection socket 300 can be divided into horizontal angle adjustment and pitch angle adjustment, and thus the connection socket 300 can be adjusted to a target angle more intuitively and effectively. Meanwhile, when the horizontal angle of the connecting seat 300 is adjusted, the connecting ball 500 can obtain the supporting effect of the self-balancing mechanism 700, so that the self weight of the photographing device is hard to influence the horizontal rotation of the connecting ball 500, and thus more accurate adjustment effect can be realized.

In some embodiments, referring to fig. 2, the connection holder 300 is provided with a connection structure 350 for connecting with the photographing apparatus. The connection structure 350 may achieve connection between the connection holder 300 and the photographing apparatus, or release the connection effect between the connection holder 300 and the connection apparatus, so that the connection apparatus is fixed on the connection holder 300 and supported by the photographing head.

After the connecting base 300 drives the camera device to adjust the pitch angle, the connecting ball 500 will receive the moment caused by the self-weight of the device, and the moment will easily cause the connecting ball 500 to automatically sag, bend or even break. The elastic reset assembly can apply a balancing force to the connecting ball head 500, so that the moment caused by the self weight of the photographic equipment is balanced, the damage to the connecting ball head 500 is relieved, and the problem that the connecting ball head 500 automatically sags, bends or even breaks is avoided.

After the connecting block 420 is connected with the connecting ball head 500, when the connecting ball head 500 drives the connecting block 420 to turn over relative to the mandrel 710, the torsional spring 720 applies reverse elastic force to the connecting block 420, so that the moment caused by the dead weight of the photographic equipment is relieved or offset, and the problem that the connecting ball head 500 automatically sags, bends or even breaks is effectively avoided.

It is contemplated that self-balancing mechanism 700 may be comprised of other components, such as springs, not shown, disposed on both sides of connecting block 420, which compress connecting ball 500 when connecting ball 500 rotates, and which provide a counter-support force for connecting ball 500. Of course, the specific configuration of the self-balancing mechanism 700 is not exclusive, and other modifications may be made according to the actual situation, and is not limited herein.

In some embodiments, referring to fig. 8, two torsion springs 720 are respectively disposed on two sides of the connection block 420, and the two torsion springs 720 are respectively capable of applying an elastic force to the connection block 420 from the forward and reverse rotation directions of the connection block 420. The torsional spring 720 of both sides can be respectively from the both sides of connecting block 420 to apply elastic force to connecting block 420, consequently, no matter connect bulb 500 drive connecting block 420 and bow the direction or pitch over the rotation of direction, torsional spring 720 all can be for alleviating or offsetting of connecting bulb 500 and bringing power to realize the self-balancing effect, and then avoid connecting bulb 500 effectively and take place automatic flagging, buckle or even cracked problem.

Thereby, a locking effect in a horizontal direction is obtained between the mounting socket 200 and the coupling socket 300, thereby allowing an individual adjustment of a pitch direction.

In some embodiments, referring to fig. 4, the connection holder 300 is provided with a rotary plate 450 only capable of rotating, and a threaded hole is formed in the middle of the rotary plate 450; a passage 550 is arranged on the connecting ball head 500, and the connecting block 420 is positioned inside the connecting ball head 500; the pins 410 are threaded into the threaded holes and the pins 410 can be inserted through the passageways 550 and into the slots 425. The rotation of the dial 450 will cause the pin 410 to rotate in a spiral motion through the threaded hole, thereby directly and efficiently allowing the pin 410 to move relative to the passageway 550 and be inserted into the slot 425. Therefore, the connecting block 420 can drive the connecting ball 500 to rotate in the pitch direction through the pin 410, and the effect of limiting the horizontal rotation of the connecting ball 500 is achieved.

Specifically, the turntable 450 is provided with knurling on its peripheral side wall. The knurling may effectively increase the friction of the turntable 450, thereby making the turntable 450 easier to be carried along.

After the first clamping assembly 630 clamps the connecting ball 500, the connecting ball 500 is fixed relative to the housing 100. At this time, the housing 100 can be driven to horizontally rotate relative to the base 190, so as to drive the clamped connecting ball 500 to horizontally rotate together, and further achieve the effect of adjusting the horizontal angle of the connecting ball 500 under the condition of locking the pitching rotation of the connecting ball 500. And the second clamping assembly 670 can clamp the housing 100 and the base 190, so that the connecting ball 500 is completely fixed, and thus a stable photographing operation is performed.

In the process that the first control end 631 drives the turbine worm gear pair 634 to rotate, the pushing seat 635 is pushed up by the turbine worm gear pair 634, so as to push the first limiting ring 633 or the second limiting ring 637, and further the first limiting ring 633 and the second limiting ring 637 are relatively close to each other, thereby clamping the connecting ball 500. When the first control end 631 moves reversely, the pushing seat 635 will automatically sink under its own weight, thereby releasing the connecting ball 500. Thus, connecting ball 500 is effectively clamped or loosened, thereby effectively achieving a securing effect between connecting ball 500 and base 190.

Specifically, first control end 631 includes a second knob, and turbine-worm pair 634 includes a turbine and a worm that intermesh and are coupled to the second knob. The turbine is provided with a boss, the pushing seat 635 is provided with a groove, and the boss extends into the groove and can drive the groove to rotate.

Specifically, the radial dimension of the middle portion of the connecting ball head 500 is greater than the radial dimensions of the upper and lower ends thereof, and the radial dimensions of the first and second retaining rings 633 and 637 are both less than the radial dimension of the middle portion of the connecting ball head 500. When the first and second stop rings 633, 637 approach each other relatively, they will gradually approach the middle of the connecting ball 500 and clamp the middle of the connecting ball 500, so that the connecting ball 500 and the pushing seat 635 are fixed relatively.

In the process that the wedge-shaped block 678 gradually extends into, the wedge-shaped block 678 and the wedge-shaped gap 679 are pushed against each other, so that the horizontal seat 676 and the base 190 are pressed against each other, and further the horizontal seat 676 and the base 190 cannot move relative to each other, and therefore the fixing effect between the connecting ball head 500 and the base 190 can be effectively achieved.

Specifically, the second control end 671 includes a first knob, which abuts against the outer wall of the housing 100; a knob screw 672 is attached to the first knob, and the knob screw 672 is threaded into the housing 100 and is connected to the wedge 678. When the first knob is rotated, the knob screw 672 is driven to rotate together, and when the knob screw 672 rotates, the axial movement is carried out relative to the shell 100, so that the wedge-shaped block 678 is driven to move relative to the wedge-shaped notch 679 effectively.
