Embodiment Construction
[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. A preferred embodiment of the invention is shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.
[0031] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," "horizontal," "vertical," and similar expressions are used herein for purposes of des...

The invention relates to a charging system for a cleaning robot. The charging system comprises a charging station and a cleaning robot, wherein the charging station comprises a charging end, a signal source containing part and a signal source arranged within the signal source containing part, the signal source containing part comprises an upper part and a lower par, a plurality of emission windows distributed around an outer wall are arranged on an outer wall of the containing part, and the upper-part emission windows and the lower-part emission windows are transversely and vertically distributed in a staggered way; the cleaning robot comprises a connecting terminal, a receiving part and a control part; the connecting terminal is connected with the charging end to charge rechargeable batteries; the receiving part is used for receiving an upper-part signal and a lower-part signal emitted from the signal source; and the control part is used for controlling the cleaning robot to return back to the charging station to be charged according to the upper-part signal and the lower-part signal. The invention further relates to a charging station and a method for controlling the cleaning robot to automatically return back to the station to be charged. According to the invention, a position signal emitted from the signal source is divided into the upper-part signal and the lower-part signal, so that a very large range can be covered by the position signal, and an overlapping region is hard to generate.
Description
technical field [0001] The invention relates to vacuum cleaner technology, in particular to a charging system for a cleaning robot, a method for a cleaning robot to automatically return to a station for charging, and a charging station. Background technique [0002] A cleaning robot usually refers to a device that automatically moves in a predetermined working area and performs specified cleaning work without operator operation. [0003] The cleaning robot is usually equipped with a rechargeable battery for its power and forms a system with an external charging station (charging device), and the cleaning robot can return to the charging station to recharge the rechargeable battery when necessary. Therefore, the cleaning robot must know where the charging station is. [0004] When the traditional cleaning robot goes back to the station to charge, it needs the charging station to emit position signals, usually by emitting infrared rays through multiple infrared emission sourc...
