Three-degree-of-freedom bionic neck movement mechanism

Abstract

The invention provides a three-degree-of-freedom bionic neck movement mechanism. The three-degree-of-freedom bionic neck movement mechanism comprises a base, and further comprises a torsion mechanism,a pitching mechanism, a side swing mechanism and a connecting sliding block which are arranged on the base; the connecting sliding block comprises a support, rolling wheels and a head and neck connecting part; the rolling wheels are arranged at one end of the support, and one end of the head and neck connecting part is movably arranged at other end of the support in a penetrating mode; the side swing mechanism comprises a pitching track used in cooperation with the rolling wheels and a side swing assembly arranged on the base and capable of driving the pitching track to swing, the connectingsliding block is connected with the pitching track through the rolling wheels in a rolling mode, and the pitching mechanism comprises a side swing head and a pitching assembly capable of driving the side swing head to swing; the swing plane of the side swing head is perpendicular to the swing plane of the pitching track; and one end of the torsion mechanism is connected with the base, and the other end of the torsion mechanism penetrates through the side swing head to be connected with the head and neck connecting part. According to the three-degree-of-freedom bionic neck movement mechanism, the pitching mechanism, the side swing mechanism and the torsion mechanism cooperate with one another, the bionic degree is high, the rotation flexibility is higher, and the operation is more flexible.

Description

technical field [0001] The invention relates to the field of bionic neck joints of robots, and more specifically, to a three-degree-of-freedom bionic neck motion mechanism. Background technique [0002] The components of robots are already common in daily life. In actual production, the control and manipulation of the neck movement of the robot often occurs. The neck movement is mainly performed in three orthogonal planes, namely, pitching movement, lateral movement and horizontal movement. rotational movement; [0003] At present, there are many cylinder-driven or steering gears connected in series to realize the movement of three orthogonal planes of the mechanical neck. However, these equipment mechanisms have a neck motion trajectory that is not bionic, and the operation is not smooth enough, the degree of bionics is not high, and the operation is not flexible enough; for example, Chinese patent CN201210574544. The mechanism can provide tilting, pitching and swaying mo...

AI Technical Summary

Problems solved by technology

[0004] The present invention overcomes the above-mentioned background technology by changing the length of each support to realize the change of the angle to complete the tilting, pitching and yaw movements; the degree of bionics is still not high in operation, and the three degrees of freedom are insufficient in compliance and coordination. To solve the problem of insufficient flexibility in operation and use, a three-degree-of-freedom bionic neck movement mechanism is provided
