Embodiment Construction

[0176] Build the computer 3D model first, then engrave the mold; then add anti-collision and brakes to the lawn mower. The technical equation and modeling method are:

[0177] Using PRO / ENGINEER WILDFIRE drawing software, set up a new working directory, create new parts, and sketch 2 concentric circles.

[0178] Open the variable section sweep (Var Sect Sweep) command, select the above 2 circles as the sweep trajectory and the reference trajectory.

[0179] Draw a straight line parallel to the plane of 2 circles, the length L=(D-d) / 2, and the projection line corresponding to the edge of the circle.

[0180] Establish parameter (PARAMETER) 1: C is a real number (real number), which can be assigned a value between 0.01-1 according to specific working conditions, such as 0.3; C is also called wave height. Establish parameter (PARAMETER) 2: N integer (integer), select a value between 2-100 according to specific working conditions, such as 13; N is also called wave number. Establ...

Abstract

Provided is a method for using ultrasonic waves to perceive sequential formation charging of multiple intelligent lawn mowers. Multiple lawn mowers are placed in a siege ring of lead wires with electromagnetic pulse covering the ground along the border of a mowing work area, each lawn mower is provided with a compass, each compass is used for orientating to maintain order and arrange the multipleintelligent lawn mowers into a team; radars which use ultrasonic waves to perceive the multiple intelligent lawn mowers are built between a power supply assembly and each lawn mower, the ultrasonic waves are transmitted and received by an emitter and a receiver, the ultrasonic waves are converted into processing signals, a local area network is used to communicate with the multiple intelligent lawn mowers, and a beidou system is used to position sites, the sites are communicated with each other to be arranged in order for charging; the intelligent lawn mowers adopt an intelligent charging management scheme, according to the actual power status of a battery pack, different charging strategies are adopted, it is ensured that the system work reliably, and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to a lawn mower used for mowing lawns in courtyards, parks, roads and other places, and is an intelligent lawn mower with a charging assembly for automatically inserting and pulling out a contact piece with a charging pin. It includes an anti-collision fuse located at the front of the lawn mower chassis, a logarithmic spiral brake with an anti-collision insurance that can self-stop, a low-vibration leaf blower, and an additional dust bag. Brackets, tie openings and dust outlet of the main body are equipped with soft blades, blades for blowing impellers, safety circuits and double switches for circuits, noise reduction and vibration reduction and honeycombs, the rollers can be changed to steerable, and integrated blowing suction and grass cutting Based on the multifunctional lawn mower with hose reel for watering and fertilizing and spraying liquid lines and the intelligent lawn mower with automatic charging pin insertion and extract...
