Driving vehicle, specially cleaning robot, in particular for swimming pools with means for automatically changing the driving direction in front of an obstacle

摘要

The robot has two independent rear driving wheels (1). It has two obstacle detection arms (2) located on each of its front sides. Each driving wheel is driven from a drive shaft (8) through a rotation inverter. A connector (7) is interposed between each detector and the wheel drive. The obstacle detectors and the connector are arranged so that, when the vehicle encounters an obstacle, the detector activated by the obstacle activates the inverter so as to change rotation of the drive wheel from forwards to rearwards. Each obstacle detector arm is in the shape of a moustache. It has an active edge (3) projecting frontwards and extending over the vehicle half-width and the corresponding corner of the vehicle is opposite the drive wheel to which the arm is functionally associated. The arm opposite end (6) is located near the drive wheel which it controls and is supported to rotate freely on a vertical rotational axis (5).
