Problems solved by technology

But there are still problems. It is difficult to set the time for this setting. If the time is set short, some bumps and weightlessness will also cause misjudgment. If the time is set for a long time, if the person really leaves and the car is still moving, this will cause danger.

Abstract

The invention discloses a mowing machine with a seat detection mechanism. The mowing machine comprises a chassis, a seat and a proximity switch are arranged on the chassis, and one end of the seat isrotatably connected to the chassis; a spring is arranged at the bottom of the other end of the seat, the proximity switch is located at the bottom of the seat, and the mowing machine further comprisesa weighing device and a computer; the weighing device moves along with the seat and is provided with a mass with known weight, the weighing device sends the weight obtained through real-time measurement to the computer, the computer compares the weight obtained through real-time measurement with the weight of the mass, and if the ratio of the weight obtained through real-time measurement to the weight of the mass is smaller than 0.5, when the seat is not in contact with the proximity switch, it is also judged that a person sits on the seat.

Description

technical field [0001] The present invention relates to a lawnmower. Background technique [0002] For the sake of safety, the seat detection mechanism is installed on the lawn mower at present. The main function of the seat detection mechanism is to detect whether there is anyone on the seat. The safety standard stipulates that when there is no one on the lawn mower seat, the engine will automatically closed. [0003] The current seat detection mechanism mainly includes a proximity switch arranged under the seat. The bottom of the seat is provided with a spring support. When there is someone on the seat, the weight of the seat itself plus the weight of the person can make the seat contact the proximity switch. There is a problem that when the lawn mower is in a bumpy state, even if there are people on the seat, sometimes it will Because of the weightlessness, the proximity switch cannot contact the bottom of the seat. At this time, misjudgment will occur. [0004] A sol...
