Lawnmower including electrostatic discharge
A walk-behind lawnmower includes a housing including a metal chassis, a handle coupled to the housing by support beams, a battery pack interface configured to receive a battery pack, a motor housed within the housing, a plurality of wheels attached to the housing, one or more cutting blades configured to be driven by the motor, and a skirt coupled to the metal chassis of the housing. The skirt is configured to provide a conductive path to discharge an electrostatic charge accumulated on the metal chassis.
1 . A walk-behind lawnmower comprising:
a housing including a metal chassis;
a handle coupled to the housing by support beams;
a battery pack interface configured to receive a battery pack;
a motor housed within the housing;
one or more cutting blades configured to be driven by the motor; and
a skirt connected to the metal chassis of the housing, wherein the skirt is configured to provide a conductive path to discharge an electrostatic charge accumulated on the metal chassis, and wherein the conductive path comprises a rigid metal frame placed around a circumference of the skirt.
2 . The walk-behind lawnmower of claim 1 , wherein the skirt comprises a metalized plastic.
3 . The walk-behind lawnmower of claim 1 , wherein the skirt comprises a conductive polymer.
4 . A walk-behind lawnmower comprising:
a housing;
a handle coupled to the housing by support beams;
a battery pack interface configured to receive a battery pack; a motor housed within the housing;
one or more cutting blades configured to be driven by the motor; and
a skirt coupled to the housing, wherein the skirt includes a conductive path molded into an outer surface of the skirt, and the conductive path is configured to discharge an electrostatic charge accumulated on the housing;
wherein the conductive path comprises a first conductive path coupled to a first end of the skirt and a second conductive path coupled to a second end of the skirt spaced apart from the first end of the skirt, and wherein the first conductive path and the second conductive path are separated by a non-conductive portion of the skirt.
5 . The walk-behind lawnmower of claim 4 , wherein the first conductive path and the second conductive path includes a metal strip.
6 . The walk-behind lawnmower of claim 5 , wherein the metal strip is composed of one selected from a group consisting of copper, aluminum, brass, and gold.
7 . The walk-behind lawnmower of claim 4 , wherein the skirt is composed of a non-conductive material.
8 . A method of discharging electrostatic buildup of a walk-behind lawnmower, the lawnmower including a housing including a metal chassis, a motor housed within the housing, and a battery pack interface configured to receive a battery pack, the method comprising:
detecting, via a controller, actuation of an input device;
controlling, via the controller, the motor based on actuation of the input device; and
discharging, via a rear skirt connected to the metal chassis, an electrostatic buildup accumulated on the metal chassis of the lawnmower, wherein the rear skirt comprises a conductive path including a rigid metal frame placed around a circumference of the rear skirt.
9 . The method of claim 8 , wherein the rear skirt comprises a metalized plastic.
10 . The method of claim 8 , wherein the rear skirt comprises a conductive polymer.
11 . The method of claim 8 , wherein the conductive path includes a metal strip.
12 . The method of claim 11 , wherein the metal strip is composed of one selected from a group consisting of copper, aluminum, brass, and gold.
