A steel wire rope damper has characteristics of nonlinear stiffness and nonlinear damping. As compared with conventional rubber dampers, a steel wire rope damper has advantages such as strong environment adaptability, a long service life, diversified mounting manners, good buffering and anti-shock performance, great damping, and convenient mounting. Thus, the aforementioned damping device exhibits good performance in different vibration situations, and a good shooting can be achieved by effectively mitigating influences brought about to the gimbal by external vibration to reduce a vibration frequency.

In an implementation, manner of the present disclosure, another damping device for a gimbal is provided for damping vibration of the gimbal by using a composite damper including a one-dimensional damper and a three-dimensional damper. For example, the composite damper includes a gimbal damper used to be fixedly connected with the gimbal and a carrying damper fixedly connected with the gimbal damper. The gimbal damper is a three-dimensional damper that damps vibration in a three-dimensional space, and the carrying damper is a one-dimensional damper that damps vibration along a one-dimensional straight line. External vibration is transferred from the carrying damper to the gimbal damper, and then transferred to the gimbal through the gimbal damper.

The composite damper uses a one-dimensional damper and a three-dimensional damper to damp vibration jointly. The one-dimensional damper can concentrate on damping in a direction in which the vibration is more intense, so as to produce a good damping effect while keeping the cost relatively low.

Based on the aforementioned damping device, in an implementation manner of the present disclosure, a vehicle-mounted gimbal using the damping device is further provided. The vehicle-mounted gimbal includes die damping device and a gimbal connected with a vehicle-mounted hanging component through the damping device. The vibration produced by a vehicle is transferred from the vehicle-mounted hanging component to the damping device and, after passing through the damping device, is then transferred to the gimbal, so as to effectively damp vibration of the gimbal.

Referring toFIG. 9, a damping device200according to a second implementation manner of the present disclosure is basically similar to the damping device100according to the first implementation manner. Their difference lies in that a carrying damper240of the damping device200according to the second implementation manner is an elastic ball damper.

Referring toFIG. 10toFIG. 12, specifically, in the embodiment illustrated, the carrying damper240includes a base241, a mounting seat242, and at least one damping elastic member243.

In order to increase the amount of stretching of the damping elastic member243, the supporting portion2443may also have a certain elasticity, as long as a binding force between the first abutment portion2441, the second abutment portion2442, and the supporting portion2443is greater than a stretching force of the damping elastic member243.

In the implementation manner, the second abutment portion2442also movably abuts against an outer surface of the mounting seat242away from the base241. In other optional implementation manners, the second abutment portion2442fixedly abuts against the mounting set242.

Here, the supporting portion2443has elasticity. By means of the elasticity of the supporting portion2443, the damping effect of the damping elastic member243can be realized. By means of the binding force between the first abutment portion2441, the supporting portion2443, and the second abutment portion2442, the amount of movement of the damping elastic member243is restricted, and the damping elastic member243is prevented from dropping from the base241and/or the mounting seat242.
