An intelligent lawn mower with front universal wheels and half-side guide grooves to expand the mowing area

Abstract

The invention discloses an improved intelligent mower with universal wheels matched with half-side guide grooves to expand mowing area. A pin ball (233a) arranged at the root of a charging pin (233) is mounted on a concave hemisphere seat, and left and right pins on a same axis of the pin ball are located in left and right U-shaped grooves respectively for the convenience of micro follow-up and impact resisting; a middle groove of narrow guide rails (233c) symmetric according to an advancing line of a unilateral front universal wheel is arranged on a single side of a bottom plate horizontally laid on the ground and can only contain the front universal wheel, left-right width of the narrow guide rails is less than half of width of the mower, and each guide rail is bell-mouthed with a cubic curve section of function curve of advanced mathematics for the convenience of relieving impact, guiding and expanding mowing area, so that the circumstance that a half close to the left is a mowing missed area or a half close to the left is a knife damaging area or a half close to the left between two guide rails which are wide originally is a guide rail damaging area is avoided, and the problem of reliable plug-pull charging in a micro follow-up manner is solved.
