Method for Operating a Gardening Appliance, and Gardening Appliance
20220117155 · 2022-04-21 ·

A gardening appliance has a traction drive system with a clutch, an electric motor drive system and a user-triggerable signalling device. The clutch is designed to, as a result of forward rotation, automatically engage for forward drive of the gardening appliance and, as a result of backward rotation, automatically disengage for freewheeling of the gardening appliance. The electric motor drive system is designed to effect the forward rotation and the backward rotation of the clutch. A method of operating the appliance includes: a) in a user-triggered manner by way of a change in a signal state of the signalling device, operating the electric motor drive system in a running-down and/or braking operating mode in order to lower a motor rotational speed of the forward-rotating electric motor drive system; b) acquiring whether a back electromotive force caused by the electric motor drive system or a variable based on the back electromotive force satisfies a standstill criterion, wherein the standstill criterion is characteristic of an attainment of a standstill state of the electric motor drive system; and c) when the standstill criterion is satisfied, operating the electric motor drive system in a backward-rotation operating mode to effect the backward rotation of the electric motor drive system for disengaging the clutch for freewheeling of the gardening appliance.

INTELLIGENT HARVESTER WITH INSTANTANEOUS STOP FUNCTIONS, AND INSTANTANEOUS STOP METHOD THEREOF
20220017083 · 2022-01-20 ·

An intelligent harvester with instantaneous stop functions includes a harvester body, a detecting system for detecting a human body within an area range on a traveling route of the harvester body, and a brake system arranged on the harvester body and operatively connected to the detecting system. When the detecting system detects a human body present within the area range on a traveling path of the harvester body, the brake system controls the harvester body to brake.

Gardening tool

A gardening tool, such as a mower, has a main body having an accessory, such as a mowing blade, and a motor for driving the accessory. A handle is rotatably connected to the main body. At least one operation assembly is associated with the handle for being operated by a user to control the motor when the handle is located in a predetermined position. A control system prevents the motor from being controlled by the operation assembly and halts the motor when the handle is located out of the predetermined position.
