Dust catcher walking device with adjustable height

Abstract

The invention discloses a dust catcher walking device with adjustable height, which comprises a driving plate, a transmission fork, a walking wheel, a guide bracket, a gear box, a walking motor and a chassis. Via toggling the driving plate, a transmission fork with certain height is toggled in and out of the guide bracket so as to restrict the distance of the walking wheel fluctuating up and down and achieve the effect of regulating the height of the dust catcher body away from the ground. The walking device comprises two walking wheel groups arranged at the middle end of the chassis of the dust catcher body. Each of the walking wheel groups can rotate along the axle direction and regulate the rotate speed of a walking motor to regulate the walking speed of the dust catcher. The walking device can enable the dust catcher to adapt to the carpet with different heights, so as to prevent the walking wheel from being blocked. The walking device can be widely applied to various types of autonomous moving dust catchers.

Description

technical field [0001] The invention relates to a walking device of a vacuum cleaner, in particular to a walking device of an autonomous mobile vacuum cleaner capable of adjusting different heights. Background technique [0002] In the 21st century, various service robots are about to enter people's daily life. The International Federation of Robotics has given a preliminary definition of a service robot: a service robot is a semi-automatic or fully autonomous robot that can complete services that are beneficial to human health, but does not include production equipment. The applications of mobile service robots can include household cleaning, hospital care; shopping guides and tour guides in shopping malls; restaurant services, hotel etiquette; community inspections, bank building security, etc. Other robots that are close to people's lives are also included. [0003] With the development of related technologies and the improvement of people's living standards, service rob...

AI Technical Summary

Problems solved by technology

However, in the existing vacuum cleaner support mechanism, although the chassis of the vacuum cleaner body encounters an obstacle, the vacuum cleaner body cannot overcome its own weight to overcome the obstacle, and the vacuum cleaner is stuck at the obstacle and cannot move forward.

But, because the support height of this support mechanism can't be adjusted and chassis and any ground all keep fixed distance, one is: when vacuum cleaner cleans on long-haired carpet, long-haired carpet can bring huge resistance to vacuum cleaner, and vacuum cleaner has It may be blocked and unable to move forward; the second is: the vacuum cleaner can pass through the long-haired carpet, but because the height between the chassis and the ground is too large, when cleaning on a general carpet, the suction of the vacuum cleaner will be small, the cleaning effect is relatively poor, and the cleaning efficiency is low. not tall
