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

Embodiment Construction

[0020] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] Such as Figure 1-4 As shown, a pan-tilt shock-absorbing mechanism of a mobile robot is characterized in that the mechanism includes an embedded upper shock-absorbing connecting plate 1, a lower shock-absorbing connecting plate 2, a transfer plate 3, a wire rope reducer assembly and a flexible support assembly 18;

[0022] The wire rope reducer assembly includes a wire rope shock absorber 17 and a spring support member 19; the wire rope shock absorbers 17 are arranged in three groups, evenly distributed along the circumference of the upper shock absorbing connecting plate 1, and their center angles are spaced at 120°. The wire rope shock absorber 17 is rigidly connected with the upper shock-absorbing connecting plate 1 by screws through the upper connector 7, and is rigidly connected with the transfer plate 3 through the lo...

Abstract

The invention discloses a pan-tilt damping mechanism of a mobile robot. The pan-tilt damping mechanism comprises an upper damping connecting plate, a lower damping connecting plate, a transfer plate and a steel wire rope speed reducer assembly which are embedded. The steel wire rope reducer assembly comprises steel wire rope dampers and a spring supporting piece. The spring supporting piece is formed by connecting a supporting rod and a spring in a nested mode, and the two ends of the supporting rod are fixedly connected with the transfer plate and the lower damping connecting plate respectively. The upper damping connecting plate, the lower damping connecting plate and the transfer plate form a multi-stage damping support; three groups of upper ball bearing supporting seats are fixedly mounted on the upper damping connecting plate; three sets of lower ball bearing supporting bases are fixedly installed on the lower damping connecting plate, and the upper damping connecting plate, thelower damping connecting plate and the flexible supporting assembly are assembled to form a first-stage damping mechanism. The upper damping connecting plate is fixedly connected with the three sets of steel wire rope dampers at the same time, and the transfer plate, the upper damping connecting plate and the steel wire rope dampers are assembled into a second-stage damping 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...
