The pitching shaft structure 1 can be used for mounting the camera 4, and the motor in the pitching shaft structure 1 drives the camera 4 to perform pitching motion around a pitching shaft; the pitching shaft structure 1 is arranged on the transverse rolling shaft structure 3, and the camera 4 is driven to make transverse rolling motion around the transverse rolling shaft by a motor in the transverse rolling shaft structure 3; the transverse rolling shaft structure 3 is arranged on the translation shaft structure 2, and the movement of the camera 4 around the translation shaft is controlled by a motor in the translation shaft structure 2.

The platform 100 further comprises at least one locking structure 5, in this embodiment, the locking structure 5 is disposed on the pitch axis structure 2, and can limit the rotation of the camera 4 around the pitch axis (hereinafter, referred to as pitch axis locking) of the platform 100 in the non-operating state. In another embodiment, the locking structure 5 is disposed on the roll shaft structure 3, and can limit the rotation of the pitch shaft structure 1 around the roll shaft (hereinafter, referred to as roll shaft locking) when the pan/tilt head 100 is in a non-operating state. In another embodiment, the cradle head 100 includes two locking structures 5 respectively disposed on the pitch axis structure 2 and the roll axis structure 3, for locking the pitch axis and the roll axis of the cradle head 100 in the non-operating state.

Although the three-axis pan-tilt is shown in the drawings, the solution provided in the embodiment of the present invention is also applicable to a two-axis pan-tilt, that is, a locking structure 5 is provided on the pitch axis structure of the two-axis pan-tilt, and the pitch axis of the two-axis pan-tilt is locked in the non-operating state by the locking structure 5.

Referring to fig. 2-3, the central axis of rotation of the roller structure 3 is indicated by the letter "Z". Fig. 2 illustrates an embodiment in which the pitch axis structure 1 is operated at an angle ranging from-45 degrees (i.e., counterclockwise to 45 degrees) to +45 degrees (i.e., clockwise to 45 degrees) about the roll axis. Fig. 4 illustrates an embodiment in which the tilt axis structure 1 rotates around the roll axis to an angle of-90 degrees (i.e., rotates counterclockwise to 90 degrees) when the roll axis is locked in the non-operating state of the pan/tilt head 100.

Referring to fig. 4-5, the pitch axis of the rotation center of the pitch axis structure 1 is indicated by the letter "X". Fig. 4 illustrates an embodiment in which the camera 4 is operated at an angle ranging from-135 degrees (i.e., counterclockwise to 135 degrees) to +45 degrees (i.e., clockwise to 45 degrees) about the pitch axis. Fig. 5 illustrates an embodiment in which the camera 4 rotates around the pitch axis to an angle of +90 degrees (i.e., rotates clockwise to 90 degrees) when the tilt axis is locked in the non-operating state of the pan/tilt head 100.

The present invention will be described below by taking an example in which the lock structure 5 is provided on the pitch axis structure 1.

Referring to fig. 6 to 11, a detailed structure diagram of an embodiment of the locking structure 5 is illustrated. As shown in the figure, the locking structure 5 includes a limiting member 51, and the limiting member 51 is sleeved and fixed on the pitch axis (i.e. the rotation axis of the pitch axis structure 1, i.e. the motor axis) of the pitch axis structure 1, and the two cooperate to enable the limiting member 51 and the pitch axis to rotate with each other. Specifically, referring to fig. 11, the inner hole of the limiting member 51 is D-shaped, and the cross section of the front end shaft section of the pitch shaft 12 is also D-shaped, so that the limiting member 51 and the pitch shaft 12 can rotate with each other in cooperation. In other embodiments, the inner hole of the limiting member 51 and the cross section of the front end shaft section of the pitch shaft 12 may be configured to have other non-circular shapes, such as a triangle or a polygon, so that the limiting member 51 and the pitch shaft 12 can rotate together after being engaged. A protrusion 511 extends outward from the periphery of the limiting member 51.

The locking structure 5 further includes a pressing cover 52, wherein the pressing cover 52 is fixed on a predetermined position of the motor base 11 of the pitch shaft structure 1, and forms a receiving groove 53 in cooperation with the motor base 11. The locking structure 5 further includes an elastic member 54 and a stop member 55 disposed in the receiving groove 53 and capable of moving up and down in the receiving groove 53. Specifically, the upper end of the elastic element 54 is fixed on the inner wall of the accommodating groove 53, and the lower end is connected with the stop element 55. When the limiting member 51 rotates and the protrusion 511 passes the position of the stopping member 55, the protrusion 511 presses the stopping member 55, the stopping member 55 compresses the elastic member 54 again, so that the stopping member 55 moves into the receiving groove 53, and after the protrusion 511 passes, the stopping member 55 returns to its initial position under the action of the elastic member 54. In one embodiment, the resilient member 54 is a spring.

In another embodiment, the limiting member 51 is provided with a limiting groove (not shown), and the stopper 55 is provided with a stopper post (not shown) for cooperating with the limiting groove of the limiting member 51. Alternatively, the limiting member 51 is provided with a limiting post (not shown in the figure), and the stopping member 55 is provided with a stopping groove (not shown in the figure) for matching with the limiting post on the limiting member 51.

In the above manner, the limiting member 51 and the pitch axis may be detachably connected. In other embodiments, the limiting member 51 and the pitch shaft are integrally formed, for example, the limiting member 51 is a slot formed on the pitch shaft, and the stop member is a stop spring engageable with the slot.

In the present embodiment, the position of the cover 52 on the motor base 11 determines the angle to which the camera 4 rotates around the tilt axis 12 when the tilt axis is locked in the non-operating state of the pan/tilt head 100. In some embodiments, the position of the cover 52 on the motor base 11 is outside the range of the operating angle of the camera 4 around the pitch axis 12 during the normal operation of the head 100, for example, as shown in the previous example, the operating angle of the camera 4 around the pitch axis 11 during the normal operation is-135 degrees to +45 degrees, the angle to which the camera 4 rotates when the preset pitch axis is locked is +90 degrees (i.e., clockwise to 90 degrees), and the position of the cover 52 on the motor base 11 is also set accordingly according to the angle (+90 degrees).

The process of implementing the pitch axis locking of the head 100 will be described in detail below.

In the operating state of the head 100, the camera 4 can rotate within its operating angle range (e.g., -135 degrees to +45 degrees in the previous example). When the pan/tilt head 100 is in the non-operating state, the camera 4 rotates to a predetermined position (for example, at +90 degrees in the previous example) along the direction indicated by the arrow in fig. 7, the camera 4 drives the pitch shaft 12 to rotate synchronously, the pitch shaft 12 drives the stopper 51 to rotate synchronously, when the protrusion 511 of the stopper 51 rotates to the position of the stopper 55, the protrusion 511 presses against the stopper 55, the stopper 55 compresses the elastic member 54, the stopper 55 moves backwards, and after the protrusion 511 passes the position of the stopper 55, the stopper 55 returns to its initial position under the action of the elastic member 54. The camera 4 is locked in this position against rotation by the force of the stop 55.

In the above embodiment, the stopper 55 is capable of extending and contracting relative to the stopper 51 due to the elastic member 54, and the stopper 51 can be positioned by the stopper 55 when the stopper 55 is extended, and can rotate freely when the stopper 55 is retracted. In another embodiment, the elastic member 54 is connected to the limiting member 51, so that the limiting member 51 can extend and contract relative to the stopper 55. The stopper 51 is positioned by the stopper 55 when extended, and is freely rotatable together with the pitch shaft when the elastic member 54 is retracted. Specifically, when the pitch shaft drives the limiting member 51 to rotate to the preset position, the limiting member 51 abuts against the stopper 55, and the limiting member 51 compresses the elastic member 54 to retract until the limiting member 51 passes over the stopper 55, and the limiting member 51 extends out and is blocked by the stopper 55.

In another embodiment, the position limiting member 51 includes an elastic position limiting portion (not shown), the position limiting member rotates to a predetermined position, and the elastic position limiting portion abuts against the stopper to generate elastic deformation until the elastic position limiting portion passes over the stopper to recover the elastic deformation.

In another embodiment, the stopper includes a stopper elastic portion (not shown), and the limiting member rotates to the predetermined position to abut against the stopper elastic portion, so as to urge the stopper elastic portion to deform until the limiting member passes over the stopper, and the stopper elastic portion recovers elastic deformation.

In other embodiments, when the locking structure 5 is disposed on the roll shaft structure 3, the pitch shaft structure 1 can rotate within the range of the operating angle thereof (e.g., -45 degrees to +45 degrees in the previous example) in the operating state of the pan/tilt head 100. When the pan/tilt head 100 is in a non-operating state, the pitch axis structure 1 is rotated to a predetermined position (for example, -90 degrees in the previous example), the pitch axis structure 1 drives the roll shaft to rotate synchronously, the roll shaft drives the stop member 51 to rotate synchronously, when the stop member 51 rotates to the position of the stop member 55, the stop member 51 presses against the stop member 55, the stop member 55 compresses the elastic member 54, the stop member 55 is driven to move backwards, and after the stop member 51 passes through the position of the stop member 55, the stop member 55 returns to its initial position under the action of the elastic member 54. Under the force of the stop 55, the pitch axis structure 1 is positioned/locked in this position and no longer rotates. In other embodiments, when the limiting member 51 rotates to the position of the stopping member 55, the limiting member 51 presses against the stopping member 55 and thus compresses the elastic member 54 connected to the limiting member 51, so as to urge the limiting member 51 to retract backward, and after the limiting member 51 passes through the position of the stopping member 55, the elastic member 54 provides an elastic restoring force to the limiting member 51, and the limiting member 51 is restored to extend and is stopped by the stopping member 55.

According to the cloud platform 100 and the locking structure 5 thereof provided by the invention, when the cloud platform 100 is in a non-working state, the rotating shaft of the cloud platform, such as the pitching shaft and/or the rolling shaft, is locked through the locking structure 5, so that the cloud platform does not swing randomly, and the cloud platform is convenient to store and carry and use by a user.

It should be noted that the locking angle of the roll axis structure 3 and the locking angle of the pitch axis structure 1 may also be within a preset working angle range, and at this time, the locking structure 5 does not play a role of limiting when the cradle head 100 is in a working state, and plays a role of limiting when the cradle head 100 is in a non-working state. For example, the roll axis structure 3 and/or the pitch axis structure 1 of the pan/tilt head 100 is provided with an accommodating groove for accommodating the locking structure 5, when the pan/tilt head 100 is in the non-operating state, the locking structure 5 protrudes out of the accommodating groove to perform the limiting function, and when the pan/tilt head 100 is in the operating state, the locking structure 5 retracts into the accommodating groove to perform the limiting function.

In addition, when the motor is in a power-off state, the rotating shaft freely rotates within a preset angle range, and is positioned by the locking structure to be in a locking state when exceeding the preset angle range. The motor drives the rotating shaft to rotate within a preset working angle range, and the preset angle range is larger than the preset working angle range.

Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
