Description

Technical Field

[0001] The utility model relates to the field of three-axis pan-tilt platforms, in particular to a three-axis pan-tilt platform for a security inspection face recognition module. Background Art

[0002] The gimbal is a supporting device for installing and fixing mobile phones, cameras, and camcorders. It is divided into two types: fixed and electric. The gimbal can be rotated at will, which is convenient for users to use.

[0003] With the advancement of pan-tilt technology, its application areas are becoming more and more extensive, but there are still some problems in its actual use: the pan-tilts on the market are mostly used to carry cameras and other equipment, and their adjustment range is small. For example, face recognition modules in hospitals, communities, security checks and other locations require a larger wide-angle to obtain information, while traditional pan-tilts cannot be well adapted, which easily leads to video blind spots. Therefore, in view of the above situation, it is urgent to develop a three-axis pan-tilt for security face recognition modules to overcome the shortcomings in current practical applications and meet current needs.

The top end of the main shaft is embedded in the housing and rotatably connected with the housing. The motor B and the protective housing are vertically installed on the side wall of the housing. The wheel disc A is horizontally arranged in the middle position inside the protective housing, and the wheel disc A is drivingly connected with the output shaft of the motor B. The wheel disc B is nested at the top end of the main shaft, and the wheel disc B is connected with the wheel disc A through a belt drive.

The positioning frame is horizontally welded to the bottom end of the main shaft, the mounting frame is horizontally arranged at the inner middle position of the positioning frame and is rotatably connected to the positioning frame, and the motor C is horizontally mounted on one side of the positioning frame.

[0011] As a further solution of the utility model: the inner diameter of the slide groove is slightly larger than the through groove, and can cooperate with the ball to slide and limit it.

[0012] As a further solution of the utility model: the top end of the connecting shaft passes through the through groove and extends to the top thereof, the ball is slidably connected with the slide groove, and the ball cooperates with the connecting shaft to realize longitudinal traction of the upper arm.

[0015] Beneficial effects: The three-axis gimbal of the security inspection facial recognition module uses a fan-shaped adjustable distance disk and an extra-long rotating part as the gimbal base. Compared with the traditional gimbal, it has a very wide activity angle, so the installed facial recognition module has a larger wide angle. At the same time, the end of the arm is equipped with a sliding ball and connecting shaft for load-bearing, which can prevent the weight of the facial recognition module from causing the arm to tilt and shake, effectively improving the stability of the gimbal.
