A cloud-tilt damping mechanism for a mobile robot

Abstract

The invention discloses a pan-tilt damping mechanism of a mobile robot. The mechanism comprises an embedded upper shock-absorbing connecting plate, a lower shock-absorbing connecting plate, a transfer plate and a wire rope reducer assembly; the wire rope reducer assembly includes a wire rope shock absorber and a spring support; the spring support is composed of a support rod and a spring nested connection, and both ends of the support rod are fixedly connected to the transfer plate and the lower shock-absorbing connecting plate; the upper shock-absorbing connecting plate, the lower shock-absorbing connecting plate and the transfer The plate constitutes multi-stage shock absorption support; the upper shock absorption connecting plate is fixedly installed with three sets of upper ball bearing support seats; the lower shock absorption connecting plate is fixedly installed with three groups of lower ball bearing support seats, the upper shock absorption connecting plate and the lower shock absorption connecting plate and The flexible support assembly is assembled into a first-stage damping mechanism. The upper shock absorbing connecting plate is fixedly connected with three sets of wire rope shock absorbers at the same time, and the intermediate transfer plate, the upper shock absorbing connecting plate and the wire rope shock absorbers are assembled into a second-stage shock absorbing mechanism.

Description

technical field [0001] The invention relates to the field of robot pan-tilts, in particular to a pan-tilt shock absorbing mechanism of a mobile robot. Background technique [0002] With the widespread application of mobile robots, gimbals equipped with multiple cameras also play an important role. The working environment of mobile robots is complex and diverse, and it needs to overcome various road conditions. Although there is a shock absorbing mechanism for the robot chassis, the vibration transmitted to the gimbal will still cause the gimbal to be unstable. Most of the existing mobile robot gimbals do not use it. shock absorber. Referring to the shock-absorbing mechanism of the UAV gimbal, the traditional shock-absorbing mechanism can only provide damping in the vertical direction, resulting in that the rotary vibration of the gimbal cannot be effectively filtered, resulting in fatigue damage to the mechanical structure of the connection loosening agent. There are follo...

AI Technical Summary

Problems solved by technology

[0003] 1. The space vertical distribution of the damping mechanism in the prior art is relatively large, and it is difficult to embed it in the pan-tilt structure

[0004] 2. The existing pan / tilt shock absorbing mechanism is difficult to meet the requirements of complex working environment

[0005] 3. The existing gimbal shock-absorbing mechanism can only provide damping in a single direction, and cannot provide rotation damping
