Intelligent mower

Abstract

The invention discloses an intelligent hay mower. The intelligent hay mower comprises a machine shell; the moving assembly is used for driving the intelligent mower to move; the cutting device comprises a cutterhead assembly provided with a cutterhead, a blade assembly movably connected to the cutterhead assembly, a connecting assembly used for connecting the blade assembly and the cutterhead assembly, and a cutting motor used for driving the cutterhead assembly to rotate; the blade assembly comprises a blade provided with a cutting edge part, when the cutting motor does not drive the cutter head to rotate, the blade is in a first state, and when the blade is in the first state, at least part of the projection of the cutting edge part in the horizontal direction is overlapped with the projection of the cutter head in the horizontal direction; the connecting assembly comprises a return part, the return part has an initial state and a deformation state, when the return part is in the deformation state, the return part can generate return force enabling the return part to return to the initial state, one end of the return part is connected with the cutterhead assembly, and the other end of the return part is connected with the blade assembly. The intelligent mower provided by the invention has relatively high safety.

Description

technical field [0001] The invention relates to the technical field of electric garden tools, in particular to an intelligent lawn mower. Background technique [0002] The smart lawn mower is an electric garden tool for mowing lawns, vegetation, etc. It has functions such as automatic walking, anti-collision, preventing out-of-line within a specified range, automatic return to charging, safety detection and battery level detection. On the whole, the intelligent lawn mower can independently complete the work of mowing the lawn, without direct control and operation by humans, and has low power, low noise, and exquisite and beautiful appearance. [0003] The intelligent lawn mower mainly includes: a control unit, which is used to control its automatic walking and perform cutting work; a casing, a mobile component used to drive the intelligent lawn mower to move, and a cutting device used to perform cutting operations, etc. In terms of use, users are more concerned about the mo...

AI Technical Summary

Problems solved by technology

If an obstacle with a low height (for example, a child's arm lying on the lawn, a small animal, etc.) enters the blind spot, the intelligent lawn mower will still maintain its direction because the ultrasonic sensor 52 cannot detect the obstacle. state of forward travel, which may cause safety accidents

If the installation position of the ultrasonic sensor 52 is lowered so that the sensing area covers the above-mentioned detection blind area, the ultrasonic sensor 52 will take the grass that normally needs to be cut ahead as an obstacle, resulting in misjudgment, and even the intelligent mowing. machine not working
