Incline sensing module for an automatic cleaner
First Claim
1. An incline sensing module of an automatic cleaner, disposed on a main body of the automatic cleaner, wherein the opposite ends of the main body are defined as a head portion and a tail portion;
- the sensing escape device of an automatic cleaner including;
a control module;
a motion module, which is coupled to the control module, where the motion module is equipped with a motor-driven wheel unit, disposed on a bottom of the main body, for controlling the movement of the automatic cleaner in mode between a forward mode taking the head portion as a head or a backward mode taking the tail portion as a head; and
an inclination limitation sensing module, coupled to the control module, where the inclination limitation sensing module includes a critical inclination angle sensing unit and an actuating element, which are outward disposed on a rear bottom of the main body, wherein the critical inclination angle sensing unit includes;
a bracket, including a top plate, a fastener and two locating blades, wherein the fastener and the two locating blades are disposed on the opposite surface of the top plate, the fastener is assembled on the main body, and the top plate faces the actuating element exactly; and
an auxiliary wheel, which is pivotally connected to the two locating blades, wherein the top plate pushes the actuating element when the auxiliary wheel is externally contacted,wherein the distance between the critical inclination angle sensing unit and the bottom of the main body is smaller than the distance between the motor-driven wheel unit and the bottom of the main body, and the inclination limitation sensing module generating a signal and transferring the signal to the control module when the critical inclination angle sensing unit is externally contacted, to make the control module drive the motion module and to switch into the backward mode.

Abstract
A sensing escape device of an automatic cleaner includes a control module, a motion module and an inclination limitation sensing module. The control module controls the motion module to drive the movement of the automatic cleaner in mode between a forward mode with head portion as a head and a backward mode with tail portion as a head. The inclination limitation sensing module coupled to the control module includes a critical inclination angle sensing unit outward disposed on a rear bottom of the main body. When the critical inclination angle sensing unit is externally contacted, the inclination limitation sensing module generates a signal and transfers the signal to the control module, to make the control module drive the motion module to switch into the backward mode. The automatic cleaner moves backward immediately when climbing a ramp, to avoid misjudging actions such as a suspension of the motor-driven wheel unit.
