FIELD OF THE INVENTION

The present invention relates to a stabilizer for shooting equipment, more particular to a stabilizer applicable for moving shooting.

BACKGROUND OF THE INVENTION

The existing stabilizers, which render a smooth motion video, are important accessory for video shooting. The stabilizers include mechanical stabilizers and electronic stabilizers, among which the electronic stabilizer has a small size and is easy to carry. As sport fans have more and more various outdoor sports, their demands for small size and good portability are increasing. For example, some sport fans would like to attach the stabilizers to racing cars, helmets or their wrists, so that the stabilizers will not interfere with their movements. However, the existing stabilizers are hard to install and are not convenient to use.

A control circuit is provided. The control circuit comprises an X-axis motor control circuit, a Y-axis motor control circuit and a Z-axis motor control circuit. The X-axis control circuit is electrically connected with the Y-axis control circuit, and the Y-axis control circuit is electrically connected with the Z-axis control circuit. The X-axis control circuit is also connected with a pose estimator circuit, and the Z-axis control circuit is also connected with the Bluetooth module.

A control box is also provided. The Bluetooth module is arranged inside the control box. A stator of the Z-axis motor is arranged on the control box. The battery is installed inside the control box to provide power supply for the whole stabilizer.

The X-axis motor, the Y-axis motor and the Z-axis motor of the stabilizer are respectively arranged with a motor drive circuit and a detection circuit. The detection circuit respectively detects an angle of the motor on three respective axes by means of a magnetic encoder. Based on the pose estimated by the pose estimator and the angle of the motor detected by the magnetic encoder, the target object may be stabilized and the rotating angle may be controlled.

The stabilizer may be controlled by a wired remote or via wireless App (short for Application). The remote is communicated with the Z-axis control circuit via serial connection, and the remote may be capable of controlling X-axis movement and Y-axis movement of the stabilizer. The Bluetooth module inside the control box is communicated with the Z-axis control circuit via serial connection under the control of the wireless App. In this way, via App, the stabilizer may be controlled by the Bluetooth module, the pitch axis and yaw axis of the stabilizer, i.e. X-axis and Z-axis, may be controlled, and also operating modes of the stabilizer may be set and debugged.

The technical solutions of the present invention have advantages as follows: the stabilizer according to the present invention is easy to install and may be controlled by a remote or via app, thereby allowing sport fans to shoot during moving. It has a simple structure with small size and has good portability.
