Driving wheel module and self-moving robot

Abstract

The invention provides a driving wheel module and a self-moving robot, the driving wheel module is arranged on the self-moving robot, and the self-moving robot comprises a rack; the driving wheel module comprises a body part, a driving wheel and an elastic element; one end of the body part is connected to the rack; the driving wheel is arranged on the body part and is driven by the driving motor;the elastic element is connected between the body part and the rack, and the elastic element is configured to provide elastic force between the rack and the body part. By means of the design, the driving wheel module provides elastic force between the rack and the body part through the elastic element, so that certain landing force is provided for the driving wheel module to maintain contact and traction with the ground, and a buffering and damping function can be provided for the driving wheel module in the walking process of the self-moving robot; therefore, the driving wheel module providedwith the elastic element forms a set of bias falling type suspension system, effective driving of the driving wheel module is ensured, and the driving wheel module has good trafficability.

[0001] Cross References to Related Applications [0002] This disclosure claims priority based on Chinese application number 201910932385.8 filed on September 29, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to the technical field of cleaning equipment, in particular to a driving wheel module and a self-moving robot. Background technique [0004] Self-moving robots currently mainly include two types: self-moving robots and mopping robots. The functions of self-moving robots and mopping robots are relatively simple. If you want to sweep and mop the floor at the same time, you must prepare two sets of equipment at the same time, which takes up double the space; There is also a combination of self-moving robot and mopping robot, and a mop is added at the end of the robot to achieve integrated sweeping and mopping.

[0004] Self-moving robots currently mainly include self-moving robots and mopping robots. The functions of self-moving robots and mopping robots are relatively simple. If you want to sweep and mop the floor at the same time, you must prepare two sets of equipment at the same time, which takes up double the space; There is also a combination of a self-moving robot and a mopping robot, and a mop is added at the end of the robot to achieve integrated sweeping and mopping. However, the mopping function in this integrated cleaning only uses a mop to move on the ground, and the mopping effect and efficiency are greatly reduced.

Among them, the driving wheels of the existing self-mobile robots are directly arranged on the chassis. When the flatness of the ground is not good, or because the driving wheels move upward relative to the chassis due to their own weight or pressure, the part of the lower end of the driving wheels exposed to the chassis is relatively small. If it is too small, it will affect the passability, and even cause the drive wheel to retract to the chassis and cause the drive to fail
