Abstract
The utility model discloses an intermittent-split repeated folding-expanding and locking-unlocking mechanism of articulated joint. The mechanism includes two pairs of intermittent gear pairs to achieve intermittent splitting of the folding, expanding, locking and unlocking. The power inputted to a joint shaft by a power source is intermittently split by the two pairs of intermittent gear pairs and is then outputted to each function mechanism. The intermittent-split repeated folding-expanding and locking-unlocking mechanism can fully utilize the space of articulated joints, and has the advantages of compact structure, centralized power and easy implementation of high-accuracy, high-reliability and large-load operation, and the intermittent-split design can obviate centralization of the mechanical structures. The intermittent-split repeated folding-expanding and locking-unlocking mechanism can be used for multi-folding-expanding spatial mechanism and multi-folding-expanding ground mechanism.
