Intelligent mowing machine with improved assembly with automatic charging pin plugging-in and pulling-out contact sheets

Abstract

The improved intelligent lawn mower with automatic charging pin insertion and extraction of the contact piece assembly can be automatically plugged and unplugged for charging; the pin ball (233a) provided at the root of the charging pin (233) is provided with a cross pin on the spherical seat, It solves the problem of reliable plug-in and plug-in charging with micro-volume follow-up. Just as a car needs a gas station, an electric lawnmower also needs a charging station. The curve section of each guide rail of the base plate laid on the ground surface is a cubic curve, so as to reduce the impact; the contact surface of the contact sheet (234) (234b) A section of curve is a logarithmic spiral, because the logarithmic spiral is that the equiangular spiral has the characteristics that the pressure angle is equal everywhere, which is beneficial to contact insertion. There are four contact pieces (234), pressure sheet torsion springs (234a) and rotating shafts. Form face-to-face double doors, corresponding to the charging pin ((233) standing on the front wall in front, so that the charging pin is inserted and pulled out, reciprocating in this way; the guide rail uses a cubic curve and the contact surface uses a logarithmic spiral .

Description

technical field [0001] The invention relates to a lawn mower used for mowing lawns in courtyards, parks, roadsides 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 the anti-collision safety device at the front of the lawn mower chassis, the logarithmic spiral brake with anti-collision safety and self-stopping, and the low-vibration leaf blower and dust bag. The bracket and the tie-in and the dust outlet of the main body shell are added with soft sheets, the blowing impeller is added with a blade, the circuit is added with insurance and double switches, and the inside and outside of the blower and suction machine are equipped with sound-absorbing and vibration-reducing materials and honeycombs, and the rollers are changed to steerable, and On the basis of a multifunctional lawn mower that changes the single extension tube into multiple extension tubes or flexi...

AI Technical Summary

Problems solved by technology

If you put the blower on the lawn mower, it is a technological progress from carrying it to rolling on wheels. It not only reduces the burden on people, but also the grass bag on the lawn mower can be much larger, and the continuous working time is longer.
