Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model provides a cradle head which is small in size and light in weight. The utility model further provides an unmanned aerial vehicle comprising the cradle head, which can be applied to occasions with severe weight requirements and has a wide application range.

Referring to fig. 1, an embodiment of the present utility model provides a cradle head, which is applied to an unmanned aerial vehicle, and includes a cradle head bracket 1, a cradle head body 2, a stepping motor 3 and a decelerator 4, wherein the cradle head bracket 1 is used for connecting with the unmanned aerial vehicle; the cradle head body 2 is rotationally connected with the cradle head bracket 1; the stepping motor 3 and the decelerator 4 are connected between the pan-tilt body 2 and the pan-tilt bracket 1 to drive the pan-tilt body 2 to rotate relative to the pan-tilt bracket 1.

It can be understood that the input end of the speed reducer 4 is connected with the stepper motor 3, and the output end of the speed reducer 4 is connected with the pan-tilt body 2 or the pan-tilt bracket 1, so that when the stepper motor 3 works, the pan-tilt body 2 rotates relative to the pan-tilt bracket 1 via the speed reducer 4.

Because the stepping motor 3 and the speed reducer 4 are combined to serve as the actuating mechanism, the output torque can be greatly improved, the size and the weight of the stepping motor 3 are reduced, the size and the weight of the whole cradle head are reduced, the cradle head is compact in structure, the cradle head is applied to an unmanned aerial vehicle, the unmanned aerial vehicle can be applied to occasions with severe weight requirements, and the application range of the unmanned aerial vehicle is enlarged.

Further, please refer to fig. 1 and 2, in order to reduce the overall size of the pan-tilt, in some embodiments, the pan-tilt body 2 includes a first lens module 5 and a second lens module 6, the length of the first lens module 5 is greater than that of the second lens module 6, a recess is formed at a position of the pan-tilt body 2 corresponding to the second lens module 6, and the stepper motor 3 and the decelerator 4 are disposed at the recess. That is, the first lens module 5 and the second lens module 6 in this embodiment have a length difference, when the lens ends of the first lens module 5 and the second lens module 6 are flush, the non-lens ends of the first lens module 5 and the second lens module 6 are staggered, so that the position of the pan-tilt body 2 corresponding to the second lens module 6 forms a recess, the stepper motor 3 and the decelerator 4 are arranged at the recess, that is, the stepper motor 3 and the decelerator 4 are hidden behind the second lens module 6, so that the stepper motor 3 and the decelerator 4 occupy other position spaces, and the pan-tilt is prevented from occupying excessive volume as a whole.

In addition, the specific structure of the speed reducer 4 is not limited in the above embodiment, and the speed reducer 4 may have one-stage speed reduction or may have two or more stages of speed reduction. In some embodiments, the speed reducer 4 is a two-stage or more speed reducer. For example, the speed reducer 4 is a two-stage speed reducer 4 or a three-stage speed reducer 4, which can greatly increase the output torque, and can further reduce the size and weight of the stepping motor 3 without changing the load.

With continued reference to fig. 1, in view of the accuracy of the control of the stepper motor 3, in some embodiments, the holder support 1 is provided with a detecting device 7, and the detecting device 7 is configured to detect whether the holder body 2 rotates to a limit position, so as to perform feedback control on the stepper motor 3. It can be understood that, due to the nature of the stepper motor 3, the given number of steps can enable the holder to rotate by a specified angle, and the accuracy of the control of the stepper motor 3 can be improved by setting the detecting device 7 to detect whether the holder body 2 rotates to the limit position.

Further, in some embodiments, the detecting device 7 and the stepper motor 3 are both connected to a controller, and the controller controls the stepper motor 3 to reversely rotate or stop according to the detecting signal of the detecting device 7. That is, in operation, when the detecting device 7 detects that the pan-tilt body 2 rotates to the limit position, the detecting device 7 transmits a detection signal thereof to the controller, and the controller controls the stepping motor 3 to reversely rotate or stop according to the signal.

Referring to fig. 3 and 4, in some embodiments, the detecting device 7 includes a first detecting device 71 and a second detecting device 72, where the first detecting device 71 is configured to detect whether the pan-tilt body 2 rotates to a first limit position; the second detecting device 72 is configured to detect whether the pan-tilt body 2 rotates to the second limit position, and the pan-tilt body 2 can rotate between the first limit position and the second limit position. That is, when the first detecting device 71 detects that the pan-tilt body 2 rotates to the first limit position, the step motor 3 is turned in place, and at this time, the step motor 3 can be controlled to stop moving or rotate reversely; similarly, when the second detecting device 72 detects that the pan-tilt body 2 rotates to the second limit position, it indicates that the stepper motor 3 rotates in place, and at this time, the stepper motor 3 can be controlled to stop moving or rotate reversely.

In addition, the specific structure of the detecting device 7 and the detecting principle thereof are not limited in the above embodiment, as long as it can detect whether the pan-tilt body 2 is rotated to the extreme limit. In some embodiments, the detection device 7 is an infrared detection device 7. That is, when the pan-tilt body 2 rotates to the limit position, the pan-tilt body 2 shields the infrared light of the infrared detection device 7, so that the electric signal output by the infrared detection device 7 is changed, and the purpose of detecting the rotation of the pan-tilt body 2 to the limit position is achieved.

In addition, referring to fig. 1, in order to dissipate heat of the lens module, in some embodiments, the pan-tilt body 2 includes a front shell 21 and a rear cover 22, and the rear cover 22 is a heat dissipating member. That is, the present embodiment provides the rear cover 22 as a heat sink, and uses the rear cover 22 to dissipate heat from the lens module. For example, the rear cover 22 is a metal material, and/or the rear cover 22 is provided with heat radiating fins or the like.

With continued reference to fig. 1, in view of ease of installation, in some embodiments the stepper motor 3 and the decelerator 4 are integrated. That is, the stepping motor 3 and the decelerator 4 are integrated, and when assembled, the stepping motor 3 and the decelerator 4 are integrally mounted on the holder body 2 or the holder bracket 1, so that the installation is convenient.

In addition, to protect the stepper motor 3 and the decelerator 4, please continue to refer to fig. 1, in some embodiments, the stepper motor 3 and the decelerator 4 are provided on the rear cover 22 of the pan-tilt body 2, and the rear cover 22 is connected to the cover 8 for shielding the stepper motor 3 and the decelerator 4. That is, the present embodiment shields the stepping motor 3 and the decelerator 4 with the cover 8, thereby playing a dust-proof role for the stepping motor 3 and the decelerator 4.

Further, to limit the output shaft of the speed reducer 4, please continue to refer to fig. 1, in some embodiments, the cradle head support 1 is provided with a mounting bracket 9 for rotatably supporting the output shaft of the speed reducer 4. That is, the present embodiment rotatably supports the output shaft of the speed reducer 4 with the mounting bracket 9 so that the output shaft has only one degree of rotational freedom.

In addition, referring to fig. 1, in the foregoing embodiments, in order to facilitate connection between the pan-tilt-head stand 1 and the unmanned aerial vehicle, in some embodiments, the pan-tilt-head further includes a shock-absorbing ball 10 for connecting the pan-tilt-head stand 1 and the unmanned aerial vehicle.
