Title: SAFETY DEVICE FOR CLEANING ROBOT AND CLEANING ROBOT SYSTEM USING SAME
Abstract:
Disclosed is a safety device for a cleaning robot and a cleaning robot system using the safety device. The safety device comprises a main body (100). One side of the main body (100) is provided with a holding member (11) for adsorbing the safety device onto a fixed surface. The main body is provided with a rotor (4), a safety rope (5) is fixed to and wound around the rotor (4), and a free end of the safety rope (5) is connected to the cleaning robot. The rotor (4) is provided with a stop swing arm (9), and the main body (100) is correspondingly provided with a stop groove (13), with the opening of the stop groove (13) being in opposite direction of the rotating direction of the rotor (4). The rotor (4) is connected to a reset spring (3). The safety device, in a self-locking way, enables locking immediately when a window-cleaning robot falls off, so that the operation safety of the window-cleaning robot is not limited by the length of the safety rope, so that the window-cleaning robot is more reliable, has a simple structure with few components and parts, has low maintenance costs, is flexible in movement, and is effectively optimized in both product costs and operating efficiency.
