Photographic assembly and unmanned aerial vehicle
First Claim
1. A photographic assembly, comprising:
- a pitch motor, comprising a first stator portion and a first rotor portion coupled to the first stator portion, wherein the first rotor portion is capable of rotating around a pitch axis relative to the first stator portion;
a roll motor, comprising a second stator portion and a second rotor portion coupled to the second stator portion, wherein the second rotor portion is capable of rotating around a roll axis relative to the second stator portion; and
a camera, the camera being coupled to the second rotor portion of the roll motor, an optical axis of the camera being coincides with or parallel to the roll axis;
wherein the first rotor portion of the pitch motor is coupled to the second stator portion of the roll motor by a pitch axis connection arm;
wherein the pitch axis connection arm comprises a first arm and a second arm connected to the second arm;
wherein the first arm is connected to the first rotor portion of the pitch motor and the first arm is substantially parallel to the roll axis;
wherein the second arm is connected to the second stator portion of the roll motor and the second arm is substantially perpendicular to the roll axis;
wherein a distance between, the first arm and the roll axis is greater than a maximum radius that the camera rotates around the roll axis.

Abstract
The present invention provides a photographic assembly, including a pitch motor, a roll motor and a camera. A second rotor portion of the pitch motor is coupled to the third stator portion of the roll motor and a third rotor portion of the roll motor is coupled to the camera, so that a connection manner of the photographic assembly is a pitch-roll manner. When the roll motor is working, a displacement variation of the camera along a pitch axis is small. That is, a rotation interference phenomenon is weakened, so that a rotation space that needs to be reserved between the camera and the roll motor is correspondingly reduced. That is, distances between the centre of gravity of the camera and the motors are also decreased. Therefore, the photographic assembly becomes more compact at some portions, thereby achieving an objective that the volume, the weight, and the moment of inertia of the photographic assembly are reduced.
