AI Technical Summary

Technical Problem

The existing single-axis hinge structure of the control joystick and main unit of the floor scrubber results in poor walking stability, difficult operation, and inability to achieve adaptive tilting on inclined surfaces and multi-dimensional steering in narrow spaces.

Method used

The automatic locking mechanism works in conjunction with the hinge assembly to achieve multi-degree-of-freedom adjustment and locking functions of the control lever. The angle is fixed or unlocked by driving the connecting pin through a linear drive motor or drive cylinder.

Benefits of technology

It reduces the difficulty of operation, reduces the continuous force applied to the wrist, and improves the flexibility and effortlessness of the joystick, making it suitable for cleaning complicated corners.
