Replacing the Y-axis motor in the traditional arrangement with the motor arranged obliquely, that is, replacing the arrangement of the roll motor in the conventional equipment, avoiding the Y-axis motor (rolling motor) blocking the imaging device, and improving the stability of the user. The quality of the shot.

Based on the above technical solution, a stabilizer is provided in the embodiment, including a first motor 10, a second motor 20, and a third motor 30 that are sequentially connected by a connecting arm. The first motor 10 is fixedly mounted on the first motor mount. The stage 1 is connected to the rotating shaft of the third motor 30. Wherein, the first motor 10 is equivalent to a level motor in the conventional stabilizer device, which controls the rotation angle of the level direction; the second motor 20 is equivalent to the roll motor in the conventional stabilizer device, which controls the rotation angle in the roll direction. The third motor 30 is equivalent to a pitch motor in a conventional stabilizer device that controls the angle of rotation in the pitch direction.

Specifically, the first motor 10 is used to control the angles in the horizontal direction of the second motor 20 and the third motor 30 to achieve simultaneous rotation of the second motor 20 and the third motor 30 in the horizontal direction.

Wherein, the rotation center line α and the rotation center line β are intersected at the point a such that the rotation center line α and the rotation center line β are in the same plane. Meanwhile, as shown in FIG. 1, the angle between the rotation center line β of the second motor 20 and the rotation center line α of the first motor 10 is an acute angle, and the acute angle between the rotation center line β and the rotation center line α is shown in FIG. In the most commonly used state shown, the handle 50 is located below the first motor 10, and the second motor 20 is located below the imaging device on the stage in the height direction, which prevents the second motor 20 from obscuring the imaging device. That is, the problem that the imaging device of the conventional motor orthogonal dispersion stabilizer is blocked is avoided.

At the same time, the rotation center line α of the second motor 20 and the rotation center line γ of the third motor 30 are perpendicular to each other. Compared with the conventional stabilizer device, the stabilizer only changes the arrangement of the rotating shaft of the Y-axis motor. According to the synthesis and decomposition of the motion, the stabilizer can also realize the X-axis and the Y-axis of the stabilizer at the same time. The Z axis simultaneously adjusts the angle of each direction of the stage. At the same time, only the arrangement of the center line of the Y-axis motor in the traditional stabilizer is changed, and compared with the orthogonal arrangement method of the motor of the conventional stabilizer device, the angle adjustment of the stage is also facilitated in the algorithm implementation of the control element. .
