Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and preferred embodiments.

[0016] Such as figure 1 As shown, the five-bar motion mechanism of the mouth of the robot includes a frame 1, which is characterized in that: two motors 2 are installed on the frame; the output shaft of the motor 2 is connected to the mouth module; the mouth module is a Five-bar movement mechanism: the mouth module is composed of upper lip fixed sheet 3, upper lip left moving sheet 4 and upper lip right moving sheet 5, lower lip left moving sheet 6 and lower lip right moving sheet 7; upper lip fixed sheet 3 two The ends are rotationally connected with the output shafts of the two motors (2) through two bearings respectively, and the output shafts of the two motors 2 are respectively keyed to connect the upper lip left moving sheet 4 and the upper lip right moving sheet 5, and the lower lip left moving sheet 6 and The lower lip right...

Abstract

The invention discloses a robot mouth five-rod moving mechanism which comprises a machine frame. Two motors are arranged on the machine frame, output shafts of the motors are connected with a mouth module which is a five-rod moving mechanism body. The mouth module is composed of an upper lip fixing flake, an upper lip left moving flake, an upper lip right moving flake, a lower lip left moving flake and a lower lip left moving flake. The upper lip fixing flake is supported on the output shafts of the two motors through bearings. The output shafts of the two motors are in key connection with the upper lip left moving flake and the upper lip right moving flake respectively. The whole mouth mechanism can move through output of the motors. The lower lip left moving flake and the lower lip right moving flake are hinged to the upper lip left moving flake and the upper lip right moving flake respectively. The five-rod moving mechanism is simple in structure, can well achieve opening and closing motions of the mouth of a robot, and accordingly various mouth shape motions are achieved.

Description

technical field [0001] The invention relates to a motion mechanism of a humanoid robot, which belongs to the technical field of robots, in particular to a five-bar motion mechanism of a robot mouth. Background technique [0002] The movement of the robot's mouth is inseparable from the robot's emotional expression. It is still an important topic in the field of robotics to explore the most reasonable design scheme that is closest to the structural characteristics of the human mouth. At present, the movement of the mouth mechanism of many humanoid robots is limited to the opening and closing of the upper and lower plates. Although this solution is easy to control, it is less realistic. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcoming of poor anthropomorphic fidelity of the mouth movement of existing robots, and provide a five-bar movement mechanism for the mouth of a robot, which can realistically imitate the mouth of a ...
