A magnetic fluid damping joint for camera support

Abstract

The invention provides a magnetic fluid vibration reduction joint applied to camera brackets. The magnetic fluid vibration reduction joint comprises an upper limb mechanism, elastic sealing parts anda lower limb mechanism, wherein the upper limb mechanism comprises an upper column body and positioning mechanisms; each positioning mechanism is provided with a sliding way; a coil, a spring and a soft magnet sliding block are mounted in each sliding way; one end of each soft magnet sliding block is a large-diameter cylindrical body; each large-diameter cylindrical body is inserted into each sliding way; the other end of each soft magnet sliding block is a small-diameter cylindrical body; the lower limb mechanism comprises a shell and a lower column body; a receiving chamber is formed in themiddle part of the shell; sliding grooves are formed in the inner wall of the shell; the small-diameter cylindrical bodies of the soft magnet sliding blocks extend into the sliding grooves; the positioning mechanisms extend into the receiving chamber; the elastic sealing parts are arranged between the edge of an opening part of the receiving chamber and the upper column body; the receiving chamberis filled with magnetic fluid. According to the magnetic fluid vibration reduction joint, the upper limb mechanism is in colloidal magnetic fluid connected with the lower limb mechanism; the vibration propagation of the mechanism is effectively reduced.

Description

technical field [0001] The invention relates to a damping device, in particular to a magnetic fluid damping joint used for a camera bracket. Background technique [0002] At present, the mechanical component installed on the UAV to mount the camera is called the pan / tilt, which is a supporting device for installing and fixing the camera. It is divided into two types: fixed and electric pan / tilt. After installing the camera on the fixed platform, you can adjust the horizontal and pitch angles of the camera. After reaching the best working posture, you only need to lock the adjustment mechanism. The advantage of the fixed gimbal is that it can reduce costs, reduce weight, and save power, thereby increasing the flight time, but the disadvantages are also very obvious. During the flight of the drone, the fuselage will generate high-frequency vibrations and transmit them to the camera components. In addition, when the UAV changes the flight direction or changes the tilt angle of...
