SECURED SCREW-NUT INTERFACE FOR A ROBOTIC MOWER

摘要

A robotic mower may include a chassis, a cutting motor driving at least one cutting blade, and a height adjustment assembly. The cutting motor may be mounted on a motor bracket. The motor bracket may provide structural support for the cutting motor at an adjustable level relative to the chassis. The height adjustment assembly may include a biasing element, a screw engagement nut, and a height adjustment screw. The screw engagement nut may be operably coupled to the motor bracket to enable adjustment of a height of the motor bracket via rotation of the height adjustment screw. The height adjustment screw may rotate to translate the screw engagement nut vertically along the height adjustment screw based on an engagement of teeth on the screw engagement nut with threads of the height adjustment screw. The teeth of the screw engagement nut may be urged toward the threads of the height adjustment screw via the biasing element.
