|1. (WO2018064810) MOBILE ROBOT AUTONOMOUS CHARGING DEVICE|
|Applicants:||ZHEJIANG GUOZI ROBOT TECHNOLOGY CO., LTD.
|Title:||MOBILE ROBOT AUTONOMOUS CHARGING DEVICE|
Provided is a mobile robot autonomous charging device, comprising a charging base (1) and a charging contact piece (21). The charging base comprises a charging contact (11) and a first elastic element (13) connected with the charging contact. The charging contact piece is used to contact with the charging contact for charging. The charging base further comprises a buffer block (14), a second elastic member (15) and a mounting box (16). The charging contact is connected with the buffer block through the first elastic member. The buffer block is arranged in the mounting box. One end of the second elastic member is connected with the buffer block, and the other end is connected with the mounting box. The device can offset a deflection angle caused by misalignment during charging of the mobile robot and buffer the impact generated when the charging contact is docked with the charging contact piece, which prolongs the life of the charging device, improves charging efficiency, makes the charging more stable, and enables charging with a high current.
