Title:
DETECTION DEVICE AND ROBOTIC CLEANER
Document Type and Number:
WIPO Patent Application WO/2023/108880
Kind Code:
A1
Abstract:
A detection device and a robotic cleaner. The detection device comprises: a housing assembly (102), which comprises a lens (104); and a distance detection module (106), which is provided in the housing assembly (102). The distance detection module (106) comprises: an emitting unit (108), which is provided at the bottom of the lens (104) and used for emitting structured light; a receiving unit (110), which is provided at the bottom of the lens (104) and used for receiving reflected light formed by the reflected structured light; a control unit (112), which is provided in the housing assembly (102) and electrically connected to the emitting unit (108) and the receiving unit (110); and a shielding member (114), which is arranged between the emitting unit (108) and the receiving unit (110), at least a part of the shielding member (114) extending into the lens (104). The detection device can shield stray light generated by the structured light passing the surface of the lens (104), and can also shield stray light generated by the structured light passing through the interior of the lens (104), thereby effectively blocking the stray light generated by the structured light passing through the lens (104) from being emitted to the receiving unit (110), and thus improving the detection precision of the distance detection module (106).
